The purpose of the present study was to evaluate if main domestic vector mosquitoes, Aedes albopictus as a diurnal species and Culex pipiens as a nocturnal species, have color preference for blood feeding activity. Laboratory evaluations were performed and compared to assess color attractiveness using seven fundamental colors including black, white, red, yellow, green, blue, and purple. The test bodies selected for these experiments were BioGents Sentinel traps (BG traps) with 20g dry ice in each falcon tube, which covered outside of the traps attached with each different color of vinyl sheets. In each experiment, a pair of BG traps was placed 0.6 m away from each other in a 1.8 m x 3.7 m x 1.8 m screened enclosure. The enclosure maintained at 26±2℃, 65±5% RH, and 100 lux illumination. Evaluations were performed for two hours between 10:00 and 16:00 for each 25 Ae. ablopictus females and 15 hours from 18:00 to 9:00 for each 25 Cx. pipiens females. The attraction rates were determined by a series of 42 simultaneous pairs of sample counts of the number of mosquitoes caught in the traps at every 30 minutes. As a result, black traps collected the largest number of Ae. albopictus as a mean 0.7 of 1.0 for Mosquito Preference Index (MPI), followed closely by red, blue, and purple (MPIs, 0.6) that were significantly higher (p<0.05) than those of green (MPI, 0.5), white (MPI, 0.3), and yellow (MPI, 0.2). Similarly, the MPIs for Cx. pipiens were significantly higher at black and red traps (MPIs, 0.7) but the MPIs (0.3) at white and yellow traps were significantly lower than those of the other colors.

In general, hemipteran insects transmit either obligate or facultative symbionts to their offspring using various transmission mechanisms. Riptortus pedestris (Hemiptera: Alydidae) also have facultative symbiosis with Burkholderia sp. which is acquired from the soil every generation especially during 2nd instar nymphal period. This environmental symbiont transmission makes R. pedestris face a great risk of missing their symbionts, however, previous studies showed that they have intimate associations with their symbionts. Therefore, we suspected that R. pedestris 2nd instar nymphs may have a preference toward Burkholderia sp. to achieve an efficient symbiont acquisition during the limited time of window. In order to identify the preference of 2nd instar nymph, we first conducted dual-choice experiments varying with the number of 2nd instar nymphs (a nymph and 100 nymphs) in plastic cages. Furthermore, Y-tube olfactometer experiments varying with the presence of soil as medium of Burkholderia sp. were performed to determine if the insects respond to bacterial volatile induced from the symbiont. Based on our results, we observed that R. pedestris 2nd instar nymphs may not show any specific behavioral preference or response to chemical volatile from Burkholderia sp. in laboratory conditions (P >0.24). Therefore, we will further conduct a dual-choice experiment in a semi-field condition to investigate if such patterns can be detected in a larger arena simulating a more natural environment.

최근 전세계적으로 건강기능식품에 대한 사람들의 관심이 증가함에 따라 식용곤충에 대한 활발한 연구가 진행되고 있다. 국내에서도 식용곤충에 대한 활발한 연구가 진행되고 있으며, 그 중 흰점박이꽃무지는 동의보감에서 효능을 인정받아 식량자원으로써 연구되고 있다. 이에 근거하여 본 연구에서는 흰점박이꽃무지 성충의 먹이에 대한 선호도 조사와 사육키트 설계를 통해 생산성 증대를 꾀하고자 하였다. 흰점박이꽃무지 성충에 대한 먹이 선호도 조사는 단백질의 함량과 당도, 그리고 알부민의 함량을 달리하며 실험을 수행하였다. 단백질 함량의 실험의 경우 0 %, 1 %, 5 %, 10 %에 대한 연구를 진행하여 이 실험을 통해 단백질의 함량은 흰점박이 꽃무지의 먹이 선호도에 영향을 미치지 않는다는 것을 알 수 있었다. 당도의 경우 과일의 당도범위를 기준으로 하여 15 brix, 20 brix, 25 brix, 30 brix에 대한 실험을 진행한 결과, 20 brix가 흰점박이꽃무지가 가장 선호한다는 결론을 얻을 수 있었다. 또한 계란 흰자의 주요 단백질 성분인 알부민의 경우 0 %, 10 %, 15 %, 20 %에 대한 실험을 진행하여 알부민의 함량이 적을수록 선호도가 더 높다는 것을 알 수 있었다. 먹이에 대한 선호도조사를 사육키트 설계에 반영하여 흰점박이꽃무지 성충의 사육키트는 실제 사육장의 인터뷰를 참고하여 온도 28 °C와 습도 40%로 자동으로 조절되도록 설계하였다. 사육키트의 온도는 사육키트의 바닥에 부착된 전기 매트를 통해 조절하고 습도는 사육키트의 측면에 위치한 팬을 통해 조절된다. 또한 먹이를 간편하게 제공할 수 있도록 먹이배급장치를 별도로 설계하였다. 본 연구의 의의는 흰점박이꽃무지의 성충에 대한 먹이 선호도 조사와 사육키트의 설계를 통해 미래 식량자원으로 이용될 수 있는 흰점박이꽃무지의 생산성에 대한 연구를 제안한다는 점에 있다.

도마뱀부치(Gekko japonicus) 성체와 유체의 주야간에 있어 서로 다른 은신처에 대한 선호 및 경쟁 양상을 알아보기 위하여 실내 사육장에서 성체 9개체(암컷 3, 수컷 6), 유체 4개체를 47일간 사육하면서 연구를 수행하였다. 실험결과, 사육장 내에 설치된 은신처 내부의 온도와 내부에서 발견된 도마뱀부치의 체온은 높은 양의 상관을 보였으며, 야간에 은신처 내부보다 외부에서 더 많은 성체와 유체가 관찰되었다. 성체와 유체 모두 특정 은신처에 대한 선호를 보였는데, 특별히 성체는 주간에 온도가 높은 은신처를 더 높은 비율로 선호하였다. 유체가 가장 선호한 은신처는 주야간에 동일한 은신처였다. 최대비율로 이용한 특정 은신처의 이용률은 성체의 경우 주야 간 차이가 유의한 반면, 유체는 차이가 없었다. 체온의 경우 성체와 유생 모두 야간에 은신처 외부에서 발견된 개체가 내부에서 발견된 개체들보다 더 높았다. 성체와 유생 사이의 체온 비교결과, 주간에 성체의 체온이 유체보다 높았으나, 야간에는 차이가 없었다. 이러한 결과는 도마뱀부치가 야행성으로 나은 온도조건을 가진 은신처를 선호하고 성체와 유체 간에는 은신처 이용경쟁이 있음을 보여주며, 더불어 도마뱀부치의 체온과 활동성에 관한 기초정보를 제공해 준다.

This research was conducted to examine factors affecting tweens´ brand preference for mobile network choice decisions. The results suggest that mobile network providers’ attributes, satisfaction and perceived risk have significant impact on brand preference. Further, tweens´ choices are more likely to be affected by the choices of other people within their local (district) geographic area.

People prefer a certain gain over an uncertain one (e.g., Kahneman and Tversky 1979; Gneezy, List, and Wu 2006), and uncertainty threatens the perception of personal control (e.g., Simonsohn 2009; Sonsino 2008; Gaucher, Hafer, Kay, & Davidenko, 2010). Nevertheless, research has also showed that under certain circumstances people love uncertainties as “surprises” can add unexpected pleasures to our life (Goldsmith and Amir 2010; Shen, Fishbach, and Hsee 2015). In this research, we examine consumers’ preference for surprise in the subscription services. A typical subscription business offers a “surprise-me” option, where customers receive the package without knowing what items are included, in addition to (or instead of) customers making their own selections (referred to as the “self-selection” option hereafter). Despite the surging popularity of this business model, little is known whether consumers prefer making their own selections or are willingly let providers surprise them. Theoretically, it offers an opportunity to examine consumers’ willingness to relent their control in choice when there are risks involved. Managerially, answers to these questions can help service providers better design the surprise-me option for both operational efficiencies and customer satisfactions. Our key hypothesis is that a sense of personal control is an important condition for consumers’ preference of the surprise-me option in subscription services. Feeling of control serves as a safeguard and thus allows consumers to attend to the pleasures of uncertainty. This also means that in situations where consumers do not feel in control, their preference for the surprise-me option decreases (relative to the in-control condition). This is because, the compensatory control theory (Whitson & Galinsky, 2008; Kay et al., 2008; 2009) suggests that when consumers feel not in control, they tend to compensate by trying to take things into their own hands (e.g., self-select) to regain control rather than relenting control to others (e.g., to be surprised). However, when it is difficult to regain control through self-selection due to choice difficulty (e.g., lack of topical knowledge), they may again prefer surprise as a way to simply delegate the choice (Aggarwal and Mazumdar 2008; Steffel and Williams 2017). Thus, we expect feeling of control to play an important role in preference of a surprise-me option. We conducted three studies to test this prediction. Overall, the set of studies supported the expected important role of feeling of control. The surprise option is valued only when consumers do not lack the sense of control hence do not need to regain it through choice or the chance of regaining control through choice is low due to choice difficulty (expertise or product assortment characteristics). Our research provides important theoretical contributions.

In recent times of global turbulence, democracies in many countries have been tested for their resilience and there is a need to focus on determinants of political brand preference. For political parties, from political marketing strategy point of view, analyzing factors impacting voters’ party preference is becoming important for better understanding of voters to influence and predict voting behavior. Research studies propagate that consumers can experience a feeling of love for their brand (Albert et al., 2008; Batra et al., 2012). Carroll and Ahuvia, (2006) view that consumer feels love for the brand when a brand reaches both high real and desired level of integration with the consumer’s sense of self. Brand love is the degree of strong emotional attachment a satisfied consumer has for a particular brand. Brand love includes passion and declarations of love for the brand. Though brand love has been studied in the context of consumer market, we still know little about whether voters feeling of brand love for the political party they prefer. In this backdrop, in this study, we have examined impact of political brand love on voters’ preference of the political party. As brand love is a relational construct, objective is to investigate the type of causal relationship exists among brand love and the related constructs. In this study, we have taken India, largest democracy of the world, as our focal point of study. In this paper we propose to study the mediation effects of inner self (IS) and social self (SS) while estimating the relationship between brand love (BL) and brand preference (BP) and brand trust (BT) and BP. Additionally we also look at the relationship between BL and BT. The results as a whole shows that both brand trust and brand love have significant positive impact on brand preference. Higher brand trust leads to higher brand preference both directly and when both direct and indirect effects are considered as a whole. On the other hand there is no statistically significant indirect effect of brand trust on brand preference through inner self or social self. In case of brand love on the other hand all the effects are statistically significant. Higher brand love increases brand preference directly and also indirectly through inner self and social self. This implies that higher brand inner self and social self enhances the impact of brand love on brand preference.

Consumers tend to anthropomorphize brands and treat products under the anthropomorphized brands as if they were human beings. Previous research has pointed out that there could be two kinds of anthropomorphized brands, i.e., servant and partner brands and claimed that typical consumers (non-materialists) prefer brands-as-partner, whereas materialists prefer brands-as-servant. However, there is room for improvement: (1) Previous studies have examined only brands-as-servant and brands-as-partner and brands-as-master have been ignored; and (2) they have regarded materialists as a unidimensional construct, though it can be divided into instrumental and terminal materialists. Thus, we conducted multiple comparison tests among the three kinds of anthropomorphized brands with a dataset of three kinds of consumers. The results showed that non-materialists, instrumental materialists, and terminal materialists prefer, brands-as-partner, brands-as-servant, and brands-as-master, respectively.

Introduction The concept of “processing fluency” has been widely discussed in various areas, including marketing and consumer behavior (Janiszewski and Meyvis, 2001; Labroo et al., 2008; Herrmann et al., 2013; Shen and Rao, 2016). Processing fluency is defined as the ease with which people process information, and it has been found that experiencing fluency while processing information has a positive effect on decision making. Many researchers have shown that fluency elicits positive evaluation. For example, the mere-exposure effect has been explained by processing fluency; repeated exposure to a stimulus increases processing fluency and the fluency, in turn, increases positive affect (Arkes, 2013; Janiszewski and Meyvis, 2001). Many factors have been examined in fluency studies. Among them, the most common method to affect fluency is font manipulation (e.g., Alter et al., 2007; Alter and Oppenheimer, 2008). In these studies, researchers examined processing fluency of objects with clear fonts or unclear fonts and found the former enhanced processing fluency and thus caused positive evaluation for the objects. There are many other factors related to visual perceptual fluency, such as contrast of letters and background, exposure time, and so on. Processing fluency can be influenced by eye movement. For example, Shen and Rao (2016) focused on the relation between fluency of eye movements and product evaluation. They found that repetition of an eye movement could enhance perceived fluency and that this perceived fluency could increase product evaluation. In their second experiment, they manipulated participants’ eye movement by moving a ball on the computer screen and found that the consistency between the direction of eye movement and the direction of products (pen and sports shoe) could enhance processing fluency and product evaluation. Similar to the study of Shen and Rao, we focus on the relation between the direction of products and processing fluency. Shen and Rao focused on eye movement, whereas our study concentrated on human body movement—namely, walking and riding. There are many advertisements in stores, trains, buses and on the roads. Consumers often see these advertisements while walking or riding. In these cases, they move to certain directions, and sometimes products in advertisements convey direction (e.g., automobiles, shoes, pens, and so on). At the time of exposure, consistency between two directions (consumer’s movement and product) may influence processing fluency and product evaluation. In a walking condition, the direction of physical body movement of the participants can be related to their eye movements. However, in a riding condition, the moving direction of a vehicle the participant rides does not always coincide with the direction of participant’s eye movement. We can therefore assume that if consistency of the two directions affects the product evaluation positively not only in a walking condition but in a riding condition, it is possible to verify the existence of the effects of human body movement. Based on the above considerations, we conducted two experiments. Empirical Studies In two experiments, all participants were undergraduate students at a major university in Tokyo. They were recruited at a university campus or via social network services. The experiments were conducted in two conditions: participants looking at the advertisement while walking or riding on the bus. In prior research focused on eye movement (Shen and Rao, 2016), the researchers examined the relation between eye movement and product location (left side or right side on the advertisements) as well as product direction (directed toward the left or toward the right). They showed that the participants preferred the product directed toward the right (pen or sports shoe) or located on the right side (cupcake) when their eyes moved from left to right. Conversely, the participants liked the product directed toward the left or located on the left better when their eyes moved from right to left. Based on their study, we also chose two types of products, sports shoe and bottled water. Sports shoe has a horizontal direction, so we can place the product in the advertisement with a particular direction (toward the left or toward the right). On the other hand, bottled water does not have horizontal direction, thus we use the product with a particular location (placed on the left side or right side in the advertisements). We hypothesize that the participants will experience processing fluency and express a greater preference towards the products in the advertisement when its direction or location matches the moving direction of the participants. Experiment 1 One-hundred-and-twenty students participated in a 2 × 2 between-subjects factorial design. Participants were randomly assigned into four groups: 2 moving direction × 2 product layouts. The experiment was set up in a classroom where the advertisements were displayed on the walls. On the wall to the left side of the classroom, the advertisement for sports shoe was displayed with the direction either toward the left or the right. On the wall to the right, the advertisement for bottled water was displayed with the product location either on the left or right side. On the front wall of the classroom, an advertisement for hamburger which had neither particular direction nor location was displayed as a dummy stimulus. The participants were asked to walk around the classroom either clockwise or counter-clockwise. They walked by the wall without stopping while looking at an advertisement and then rated preference and processing fluency regarding the product shown in the advertisement immediately afterwards one by one. For the participants who walked around the classroom clockwise, the products directed toward the right (or located on the right side) might appear more natural and thus enhance their processing fluency. On the other hand, the participants who walked counter-clockwise felt fluency regarding the products directed toward the left (or located on the left side). The results supported our hypotheses. There were significant differences between matched groups and unmatched groups in both preference and processing fluency. Participants who walked around the classroom clockwise showed a higher preference and fluency regarding sports shoe directed toward the right and bottled water located on the right side in the advertisements. Similarly, participants who walked around the classroom counter-clockwise presented a higher preference and fluency regarding sports shoe directed toward the left and bottled water located on the left side. Experiment 2 In experiment 2, we used school buses running between campuses as the vehicle in which the participants looked at the advertisements. We set up two situations of placing the advertisements for considering the effect of the moving scenery outside the bus window on the perception of the participants. We placed one near the ceiling, where participants can barely see the scenery outside the window, and the other on the window, where the participants can easily see scenery moving right behind the advertisement. The participants either stood or sat on the buses and then rated preference and processing fluency regarding the products on the advertisements right after getting off the bus. One-hundred-and-two students participated in a 2 × 2 between-subjects factorial design. The participants were randomly assigned into matched-above, unmatched-above, matched-window, and unmatched-window groups. The matched condition meant that the moving direction and product layouts were consistent. When the moving direction of the bus and the product layout (direction of sports shoe and location of bottled water) were consistent, we defined matched condition. Otherwise, we defined unmatched condition. The results supported our hypotheses. For the advertisements placed near the ceiling, there were significant differences between matched and unmatched groups in both preference and processing fluency for both sports shoe and bottled water. On the other hand, for the advertisements placed on the window, there were no significant differences between matched and unmatched groups. When the advertisements were placed on the window, the direction of the moving scenery outside the bus window was opposite to the direction of the bus. This might have cancelled out the effects of moving direction. Discussion and Conclusion The empirical studies showed that for the condition of participants walking, the orientation and the location of the product pointing in the same direction as the moving direction of the participants resulted in higher processing fluency, and led to higher product preference. Meanwhile, for the condition of participants moving towards a certain direction by passive means, such as taking a bus, product preference and processing fluency increase when the advertisement is placed up near to the ceiling, and the orientation or the location of the product match the moving direction of the participants. At the same time, there is no significant difference in product preference or processing fluency when the advertisement is placed on the window. In closing, our research has provided an initial look at how consistency between two directions (consumer’s movement and product) can have significant effects on consumers’ processing fluency and product evaluation. Consumers often look at the advertisements while walking or riding and advertisers can know the main direction of consumers’ movement. In these cases, they can determine the direction or the location of the products in the advertisements considering the consistency with the moving direction of consumers. Recently, digital signage in trains and buses has become popular and advertisers can easily adjust the direction or the location of the products in the advertisements on it. Therefore, the knowledge extracted from our research may be readily available for advertisers.

Lee, Josephine. 2018. “Preference Organization as a Characterization Device in TV Sitcoms.” The Sociolinguistics Journal of Korea 26(2), 167~193. This study employs conversation analysis to examine how preference organization is exploited as a characterization device in the American sitcom, The Big Bang Theory. The analysis shows that by enacting exaggerated and overt forms of preferred actions, the relationship and personalities of the main characters are constructed in a particular light. By focusing on dispreferred turns, and especially the violations of them, the analysis also demonstrates that preference organization is used to configure the main characters as “funnily abnormal nerds” while achieving the sitcom's purpose of providing entertainment and humor. These findings shed light on the workings of fictional dialogue and the specific resources used to accomplish different identity displays of sitcom characters.

The main materials composing the outdoor space are the landscape plant materials. Even though grass plants out of landscape plant materials are efficient for water consumption and management, still, the types of grass used for landscape are extremely few. Thus, this study explores the preference on grass plants in apartment complexes to provide basic information for grass planting plan and design in the future. For this study, 171 questionnaires of two sites in Daegu and one site in Seoul were used for final analysis and the results are as follows. First, in the results of the awareness of grass plants, “do not know” (80.7%) was considerably higher than “do know” (19.3%). Second, in the results of the most preferred place for planting grass plants in apartment complexes, “trail” (31.2%) was the highest, followed by “space around the apartment building” (17.5%) and “waterscape” (15.4%). Third, for the preference on the shape of grass plants, “Upright-arching” (38.0%) was the highest, followed by “Upright-divergent” (29.2%), “Tufted” (19.9%), and “Mounded” (12.9%). Fourth, for the preferred height of grass plants, “Short size” (50.3%) was the highest, followed by “Medium size” (36.8%), and “Tall size” (12.9%). Fifth, for the preferred color of grass plants, “white” (27.7%) was the highest, followed by “green” (25.7%), “red” (20.5%), “yellow” (17.2%), and “blue” (9.0%). This information could be used as reference in case when planning and designing of grass plants in apartment complexes and further research including different regions is needed.

This study examined the potential of export items in Malaysia by investigating the awareness and preference for Korean food products. A high potential product list developed from the literature, included reports about the food export status in Korea and Malaysian food trends. An online survey was carried out with 600 consumers in Malaysia. With 435 valid responses, the average awareness of the Korean food products was 3.13, and the preference was 3.48 on a 5-point scale. The awareness and preference of Korean food products were higher in the 20s-30s group than in the older groups. In particular, the Muslim group had a higher awareness for ‘ramyon’ than the other groups, and the Buddhist group had a higher preference for ‘ginseng beverage’ than the other groups. The most well-known and preferred products were ramyon, hot noodles, kimchi, biscuits, fruits & vegetable beverage, and sauce (with Korean traditional sauce)’. Based on these results, the marketing implications of the study findings are discussed.

Each municipality is promoting signboard improvement projects, but the effectiveness is not great. The main reason for this is that when the signboard is manufactured the location of the shop is only dependent on the visual aspiration effect and it is not harmonized with the building by applying uniform design. The signboard are installed almost everywhere in the city, such as residential, natural and commercial environments. And the signboard provides various services such as traffic information and life safety to customers. Also, by applying design and functional elements, we can enhance the competitiveness of companies and improve the urban environment by enhancing the mutual connection effect of customers and space. The purpose of this study is to investigate the effect of design elements and functional elements of the signboard on customer preference. In other words, we conducted surveys and analyzes of 152 specialists and non-experts (customers, self-employed). As a result of the study, the following conclusions were drawn. First, the functions and design elements of signboards are important factors that have a positive effect on customer preference. Second, the function of the signboard has a positive(+) influence on the customer preference, and the information providing function and the corporate image side function directly affect the customer preference. Third, color elements have a positive(+) meaningful effect on customer preference. Especially, similar color sign affects customer preference positively. Fourth, the signboard design component has a positive(+) significant effect on customer preference. In particular, typefaces have a positive effect on customer preference.

본 연구는 소비자의 선호 촉감을 고려한 세면용 타월 개발에 도움을 주고자 수행되었다. 타월의 바탕조직은 동일하지만(면섬유), 파일을 구성하는 섬유의 종류가 서로 다른 3종(면 100%, 면 50% / 대나무 50%, 대나무 100%)을 시료로 선정하였다. 타월을 표준 세탁조건으로 반복세탁을 실시하였으며, 10회 세탁한 타월에 대하여 섬유유연제를 처리하여, 세탁에 따른 유연성과 흡수성(흡수속도와 흡수율) 등의 성능 변화를 고찰하고 대학생 남녀 소비자를 대상으로 주관적 감각과 촉감 선호도를 평가시켰다. 세탁횟수와 파일섬유의 종류에 따라 타월의 유연성은 유의한 차이를 보이지 않았다. 타월의 흡수성은 세탁에 따른 파일섬유의 종류에 따라 유의한 차이를 보여, 흡수속도는 대나무섬유 100%로 된 타월에서 높았으나, 흡수율은 면섬유로 된 타월이 높았다. 세탁 전 타월의 파일섬유 종류에 따른 주관적 감각 평가는 유의한 차이가 없었다. 세탁이 반복될수록 파일섬유의 종류에 따른 주관적 감각은 유의한 차이를 보였으며, 섬유유연제 처리시 더 부드럽고 매끄러우며 촉촉해진다고 평가하였다. 세탁 전 타월에 대한 촉감 선호도는 선호하는 편이었으나, 파일섬유 종류에 따른 유의한 차이는 없었다. 세탁횟수가 증가함에 따라 타월에 대한 촉감 선호도는 다소 저하되었으며, 대나무섬유로 된 타월의 촉감을 가장 선호하였다. 타월의 촉감 선호도에는 평활감, 유연감 등의 주관적 감각과 섬유유연제 처리가 영향을 주었다

The purpose of this study was to investigate dietary habits, health lifestyle, preference and intake of beverages of Chinese students in Gyeonggi area. Therefore, we try to identify the factors that affect beverage consumption. According to the analysis of the demographic characteristics of male and female Chinese students, there were 155 male students (49.7%) and 157 female students (50.3%). There were statistically significant differences between the residence period and the time of coming to Korea according to sex (p<0.05), but there was no statistically significant difference between the education level, residence type and Korean ability (p>0.05). Analysis of the differences in health-related lifestyle among Chinese students of both sexes showed statistically significant difference in alcohol drinking, smoking, and exercise according to sex (p<0.05), but no statistically significant difference in computer use time (p>0.05). According to the analysis of the dietary habits of the Chinese students, there was a statistically significant difference in the number of meals per day, breakfast, lunch, dinner, snack frequency and number of midnight snacks, but no statistically significant difference in eating out frequency. As a result of the preference test for general beverages, 4.11 points of water, 3.81 points of milk, 3.64 points of fruit and vegetable juice, 3.58 points of tea, 3.25 points of coffee, 3.22 points of carbonated drinks, 2.92 points of functional drinks, respectively. Male students were more likely to prefer water, tea, and health functional drinks while female students had higher preference for fruit, vegetable juice and vinegar drinks (p<0.05). In general, consumption of regular drinks was 4.95 in water, 3.58 in milk, 3.03 in coffee, 2.92 in carbonated drink, 2.91 in fruit and vegetable juice, 2.63 in tea, 2.07 in functional drink, and 1.44 in vinegar appear. Male students had higher intake of water, tea, carbonated drinks, and health functional drinks while female students had higher intake of fruit and vegetable juice (p<0.05). The results of correlation analysis of factors affecting the general drinking of Chinese students are as follows. The intake of tea was related to the period of residence and dietary habits, the intake of milk for breakfast, the number of snacks and midnight snacks for carbonated drinks, and the fruit vegetable juice were related to dietary habits (p<0.01, p<0.05). Key words: Chinese students, dietary habits, life habits, preference and intake of beverages

The Sasang constitution typology was analyzed through SCAT2 and a specialist to examine the correlation between the Sasang constitution and dietary pattern, and the difference in BMI and food preference according to Sasang constitution was determined. The Sasang constitution typology of the subjects was classified by SCAT2 and a specialist. Seventy-four subjects were screened by SCAT2 (SC), and 18 of them were judged by the specialist (SP). The results of SCAT2 and the specialist were consistent in 13 subjects (SS). BMI and food preference among these groups were compared. The concordance rate of SCAT2 and the specialist classification was 72.2%. The BMI in SC was significantly lower in the order of Taeeumin, Soyangin, and Soeumin, but no significant difference was observed between Taeeumin and Soyangin in SP and SS. To analyze the preference of food and the constitutional suitability, the ‘Yin-Yang food preference index’ was developed and compared with the data classified by constitutional food according to existing ideological medical theory. As a result, there were 33 food items that matched in the SP-SS, which was more than that in the SC-SP (4 items), SC-SS (6 items), and SCSP- SS (4 items). Twenty-four of the 33 matched food items were consistent with the existing constitutional food data. In conclusion, SCAT2 is a very useful tool for Sasang constitutional research, but for more objective research, it is recommended that subjects who show consistent results by different methods be targeted.

In this study, Folsomia octoculata and Folsomia quadrioculata which is common and representative Collembola species in temperate forests of Korea, were selected as potential bioindicator species. Through three years of survey of the density of the two Folsomia species and environmental factors of the sampling sites, the distribution and habitat preference of the two Folsomia species was investigated. The habitats of the two species were highly distinguished, mainly due to differences in preference for temperature, organic matter content, pH, available phosphorus. In addition, these two-species showed different preferences for vegetation. F. quadrioculata and F. octoculata were mainly found in habitat which Quercus and Pinus sp. live, respectively. This is because the distributions of two tree species are the result of interaction with temperature, available phosphoric acid, and soil organic matter content.

A native minute pirate bug, Orius minutus (L.), is a generalist predator of small insect pests such as thrips, mites, scale, etc. By comparing with Tetranychus urticae Koch in choice test, we evaluated the prey preference by counting number of prey killed for 4 hours on Amphitetranychus vienensis (Zacher), Frankliniella intonsa (Trybom), Stephanitis pyrioides Scott, and Eriococcus sp. nymph. Among them F. intonsa was the only one killed more than T. urticae by O. minutus. In no choice test, mean number of prey killed was highest in F. intonsa (7.2) followed by T. urticae (3.0), A. vienensis (2.4), Eriococcus sp. (2.0), and S. pyrioides (0.0) for 4 hours. This experiment shows that O. minutus could be a good predator for F. intonsa and T. urticae.

The purpose of this study is to reveal concrete evidence on how aesthetic preference is applied in product design by countries. Since the 19th century, the proportion has been examined various times, and the conclusions consistently showed the strong preference for the golden ratio (1:1.618). However, previous studies are mainly focused on western products that were designed by western designers, so when the same experiment conducted for the first time in Asia with the question of ‘Is the Asian subjects also likes the golden ratio?’, the result clearly revealed that Korean subjects have a significant preference for the root ratio (1:1.414) and perfect square (1:1). It demonstrates that proportion preference might be different by countries, and it also influences on everyday products. Moreover, there is not enough evidence of Asian product proportions. For this reason, this study will strive to expand the knowledge on Asian aesthetic preference by focusing on Japanese automobiles that were designed and produced in Japan. 55 iconic Japanese automobiles were analyzed for proportion and compared with 50 iconic German automobiles. The result shows that Japanese automobiles have a shorter length of 7:10 (1:1.414) ratio than German automobiles with 13:23 (1:1.769) ratio. This result proves that there is the difference in preference for the proportion of Japan and Germany, and it has already influenced on automobile proportions. This result has a strong value that finding the most appropriate proportion of automotive design is a major issue in new product development, so this can be adapted to various fields of the design process where strong cultural value exists.

This study aims to gather precise information on the real fabric color and texture, and purchasing intention of mobile shoppers buying clothes. Eighty volunteers participated in the sensory test on three smartphones with four colors and two fabricssmooth taffeta and hairy doeskin. This study carried out the posteriori test using the one-way ANOVA and Duncan test by SPSS21.0. In the analysis’ results of color preference, there were no differences among the four colors of taffeta between the smartphones, but different preferences between the red and yellow doeskin exist. In the case of the Samsung phone, which has an immense color distortion, the red fabric has a low color preference. In contrast, on the Apple phone yellow fabric had the highest preference because of its brightness. The Apple phone also has the highest purchasing intention of yellow colored taffeta, which is similar to the color preference results, although the real fabric has the opposite result. For doeskin, the real red and blue colored fabric has the highest purchasing intention. The Samsung phone has the biggest color mismatch with the real fabric. It also has the lowest purchasing intention of red taffeta fabric, while the LG phone has the lowest purchasing intention of blue fabric. Using the paired comparison method of the similarity between ‘real’ fabrics and the mobile version of fabric colors has a low similarity on all four colors of taffeta and doeskin fabrics. Therefore it can be concluded that phones do not represent the ‘real’ fabric color.
