The current study examined the influence of individual trait such as Need-For-Touch level (NFT; high vs. low) and swiping orientation (vertical vs. horizontal) on product evaluation and preference when using touch-screen interface like a smart phone and a tablet. Swiping is one of the most common interaction techniques for changing pages or searching some aligned pictures on touch-screen interface and it can be used in vertical and horizontal orientations. The experiment revealed a significant interaction between swiping orientation and NFT on preference, however the interaction on change-in-price of given products was only marginally significant. To be specific, high NFT participants reported higher preference for horizontal-swipe than vertical-swipe products, but such difference did not occur with low NFT participants. The current study illustrates the influence of swiping orientation and NFT on product preference and it provides a new perspective of design principles especially for online shopping websites.

The purpose of this study is to investigate the possibility of using the simulation landscape image by analyzing the landscape characteristics of the Landscape image and the simulation landscape image among the methods to grasp the quantitative relationship between the physical change of the user and the human response. The research subjects were set as Cheongnyang-ri station square, and the research method is as follows. A survey was conducted based on the extracted landscape adjectives for comparison of actual landscape image and simulated landscape images. In addition, image analysis, preference and complexity analysis, and decision factor of landscape preference were analyzed to Comparison analysis the characteristics of actual landscape image and simulated landscape images. The results of comparative analysis are as follows. First, it can be seen that there is no difference in the factors that affect the specificity and openness in using the simulation landscape image. Second, preference analysis shows that both the Landscape image and the simulation landscape image are the most preferred at 10% of users. Third, the complexity is low at 0% in both the Landscape image and the simulation landscape image, and 35% is high in complexity. Fourth, the comparative analysis of the decision factor of landscape preference by 'visual complexity and preference', 'User fluctuation and preference', 'User fluctuation and visual complexity' were analyzed. Therefore, it can be seen that the method using the simulation landscape image rather than the actual landscape image is more efficient when analyzing the visual cognitive characteristics.

Elderly with dementia in geriatric hospitals (EDGH) are highly dependent on hospital meals. This study evaluated the foodservices satisfaction and food preference of the EDGH. The survey was conducted on 104 elderly with dementia (21 males and 83 females) in 4 geriatric hospitals in Seoul and Incheon in November, 2016. Data were collected from interviews using a questionnaire that consisted of 6 questions for foodservice satisfaction and 24 questions (10 categories) for food preference. The data were analyzed using SPSS ver. 20.0. The satisfaction with taste, saltiness, texture, and variety in foodservices was good, but the satisfaction with the amount was not, and the reason for leaving food was its large serving size. The subjects preferred soft boiled rice, noodles, porridges, meats, fish, seafood, vegetables, and fruits. Among them, they preferred more janchiguksu, red bean porridge, beef, croaker, oyster, spinach, and banana. Regarding the cooking methods, they preferred soup, grill, and boiling, but not frying. The also preferred Chinese cabbage kimchi, but they did not prefer hard kkakdugi. They did not prefer milk because of diarrhea, but they preferred yogurt. Therefore, to provide a satisfying meal for EDGH, it is necessary to develop a friendly diet considering their food preferences.

This study surveyed the recognition, image, preference, attributes, satisfaction and revisit intention for Korean food of local Vietnamese to facilitate the globalization of Korean food. Most participants had recognized Korean food. and, they were especially aware of kimchi (김치), bulgogi (불고기) and bibimbab (비빔밥), Additionally, most repondents thought these foods represent Korean traditions and culture very well. The image of local Vietnamese for Korean food was good. Which was reflected in Korean food having “a good reputation” and a high possibility for “globalization” were high. This study also investigated 16 kinds of Korean food and found the highest preferences to be for bulgogi (불고기), followed by galbitang (갈비탕), whereas that for doenjangchigae (된장찌개) was lowest. Some of the top choice attributes of Vietnamese for Korean food were found to be in “because it is ‘colorful’, ‘prepared sincerely’, ‘plated neatly’, ‘fresh’ and ‘comes with a variety of banchans (side dishes). This is a very meaningful result, making this an important reference for the globalization of Korean food. The local Vietnamese had high satisfaction and reuse intention degree for Korean food, and especially high satisfaction with the colorfulness of Korean food. In addition, the local Vietnamese showed a very high revisit intention for Korean food.

갈색날개매미충은 발육단계별로 선호하는 기주에 차이가 있었다. 약충기간에는 수목류에 서식하기 보다는 바람과 비 등의 환경적 요인에 의해 바닥으로 떨어진 약충들이 1년생 초종부터 관목류에 이르기 까지 다양한 식물체를 섭식하였으며 특히 공주시 팔봉산 산림 속의 경우 노린재 나무, 노박덩굴, 화살나무, 엄나무, 두릅나무, 때죽나무, 멍석딸기, 복분자, 산딸기, 상수리나무, 산수유, 싸리나무, 자귀나무, 조록싸리, 철쭉, 영 산홍을 선호하였다. 성충 출현 이후 홍성군 용봉산 조사에서 산란전기간의 성충은 주로 해바라기, 달맞이꽃, 까마중을 가장 선호하였고 산란기에 접어 들면서 이들 해바라기, 달맞이꽃, 까마중 같은 1년생 초종에서의 거의 볼 수 없었고 대부분은 산란을 위하여 수목류나 관목류의 목본류로 이 동하는 양상을 보였다. 공주시 팔봉산 조사에서 산란기주는 주로 병꽃나무, 가죽나무, 갈참나무, 개모시, 고욤나무, 대추나무, 때죽나무, 매실나 무, 벚나무, 조팝나무, 산딸기, 버드나무, 산철쭉, 층층나무 였다. 갈색날개매미충의 산란정도, 산란수, 성충수는 산림 속 음지보다는 양지에서 월 등히 밀도가 높았으며 산란정도와 산란수의 경우 고도에 따른 차이는 없었으나 성충수는 고도가 낮을수록 발생량이 많았다. 본 결과는 갈색날개 매미충의 발육단계별 선호기주에 관한 보고로서 특정 시기에 선호하기는 기주를 선발하였고 이러한 결과는 추후 갈색날개매미충 유인트랩식물 개발에 도움을 줄 것으로 기대된다.

Indiscriminately installed signboards are messy in out of harmony with the urban environment. In such a case, improving signage project is needed to improve significantly the urban environment. Signboards are installed to give good perceptional effect through communication with the customer. Also, Signboards are designed to make harmonize well with the urban environment because signboards are installed in virtually every place, such as the residential environment, the natural environment, the commercial environment of the city. The design of signboards should consider functional elements as a perceptual media and the user interface communication in order to provide customers with various services such as traffic information and life safety. In this study, we analysis design and functionality the customer is seeking, and suggest design elements of signboards which can well harmonized with the urban environment.

Environmental temperature has strong impacts on the rate and efficiency of nutrient use in insects, but little is knownabout how changes in temperature influence their nutrient preference. Here we examined the effect of temperature onthe nutrient preferences of mealworm beetles (Tenebrio molitor L.) by offering them a choice between two nutritionallycomplementary diets (P:C 1:5 vs. 5:1) at four different temperatures (20, 25, 30, or 35 ̊C). Beetles selected protein andcarbohydrate in a 1:1 ratio at 25 and 30 ̊C, but exhibited a significant preference for carbohydrate at 20 and 35 ̊C. Theseresults indicate that nutrient preference can shift plastically to match the altered nutrient requirement of beetles underchanging thermal conditions. The present findings have implications for the impacts of climate warming on diet selectionin insects.

Vertical transmission of symbiont is known as the most effective way to deliver their offspring. However, it has beenreported that the bean bug, Riptortus pedestris, acquires its gut symbiont, Burkholderia sp., from its environment (e.g.soil) during the 2nd instar nymphal stage. Nevertheless, it is not unknown how they locate their symbiont. For this reason,dual-choice experiments were conducted in both solitary (a nymph) and group conditions (100 nymphs) to investigatewhether or not R. pedestris has preference on Burkholderia sp. treated or untreated solution in laboratory conditions. Inthese experiments, there was no significant difference in the preference between the two treatments. We are testing inthe Y-tube olfactometer system to evaluate the response of R. pedestris on possible chemical cues from Burkholderia sp..

Lentinula edodes shows atypical mating behaviors deviated from tetrapolar mating in outcrossing. To better understand the mating behavior, we investigated variations in the mating type genes, residing in A and B mating loci, of 129 dikaryotic strains from East Asia. Through sequence analysis of A locus, we found that hypervariable region spanning N-term of HD2-intergenic region-N-term of HD1 could represent A mating type of L. edodes. Mating and hypervariable region analyses revealed 50 unique A mating types: 27 from 98 cultivated strains, 33 from 31 wild strains, and 10 commonly found. It was also revealed that only a few A mating type alleles such as A1, A4, A5, and A7 were prevalent in cultivated strains. The A mating type in wild strains were highly diverse: 23 unique A alleles were discovered in small mountainous area in Korean peninsula. The B locus was assessed by allelic variations in pheromone (PHB) and pheromone receptor (RCB) pairs. Sequence analyses revealed 5 alleles of RCB1 with 9 associated PHBs in B sublocus and 3 alleles of RCB2 with 5 associated PHBs in B sublocus. Each RCB was primarily associated with two PHBs. This allowed us to propose 15 B mating types via combinations of five B and three B subloci. Thus, the total number of mating types in L. edodes became 750 through a combination of 50 A and 15 B. This number will further increase because of rapid diversification of A mating type and possible emergence of variants of RCBs and PHB-RCB combinations.

The purpose of this study is to investigate and characterize the visual preferences of Rural Housing Standard Plans, which are expected to increase in demand as the number of households grows, and the effects of those characterizations on people’s choices in selecting home plans. In this study, Munsell values were extracted and analyzed using color analysis, and I.R.I image adjective analysis was performed to identify the color characteristics of each model type. To analyze the effect of the most influential colors among the visual elements in the plans, questionnaires were carried out according to whether color was present or not. There was a correlation between pre-selected frequency of preference and preference of visual preference. The study tallied the number of downloads for each model provided for the site of the farmers’ village and applied a t-test to confirm whether there was a difference in visual preferences. The results were as follows. First, the colors of Rural Housing Standard Plans were N and YR series, and the image analysis results were “Oriental” and “Rural”. Second, analyzing the number of model downloads and visual preferences on the homepage (www.returnfarm.com). Third, in the results of visual preference, the wooden house ranked 2.98-5.13 and the reinforced concrete house ranked 3.68-4.48. Fourth, comparative analysis of selection frequency and visual preference showed that the rankings of the top-ranked plans were similar; all were wooden houses and had similar roof forms. Fifth, the t-test conducted to analyze preferences in the visual elements of the standard design model of rural housing revealed significant differences in preferences for the color, roof form, and size, but no statistically significant differences (at .111) between preferences for structural wooden and reinforced concrete. The reason for this was that the types of wooden and reinforced concrete were not clearly distinguished from each other by photographs. Therefore, analysis suggested that the visual factors influenced the preference of Rural Housing Standard design model. In conclusion, it is necessary to present a model considering visual factors when providing models to urban and rural residents.

In this study, we conducted an empirical analysis using structural equation modeling (SEM) by distributing questionnaires to 208 Chinese tourists who constitute the largest proportion of foreign tourists visiting South Korea. The survey was conducted in a face to face (FTF) manner with the aim to contribute to globalization of Korean cuisine through comprehensive analysis of the effects of preference characteristics of Korean wave dramas on the relationship among images, attitudes, and purchase intentions for Korean cuisine. The main actor characteristics among the preference characteristics of Korean wave dramas had a significant effect on the attitudes and purchase intentions for Korean cuisine. However, the thematic characteristics among the preference characteristics of Korean wave dramas did not have a significant effect on the purchase intentions for Korean cuisine; in addition, the production characteristics did not have a significant effect on the attitudes and purchase intentions for Korean cuisine. The eco-friendly and health images of Korean cuisine had a significant effect on the purchase intentions for Korean cuisine, and the attitudes toward Korean cuisine significantly affected the purchase intentions for Korean cuisine. Based on the results of this study, it is considered necessary to continuously publicize Korean cuisine through Korean wave dramas to build positive attitudes toward Korean cuisine through enhanced images of Korean cuisine.

이 연구는 완전 기생성 침입종인 미국실새삼(Cuscuta pentagona)의 기주선호도와 기생부위를 야외현장과 기생유도 실험 통하여 확인하여 이들 식물의 기주다양성을 알아보고 잠재적인 위해성을 제시하고자 시도하였다. 미국실새삼의 기생은 구상나무와 신갈나무와 같은 목본성 식물종(12.1%)의 목질화가 되지 않은 소지나 잎에서도 관찰되었다. 미국실 새삼의 기주식물종은 국화과에 속하는 종이 가장 많았고, 과내 차지하는 기주식물종의 비율은 사초과, 마디풀과 그리고 콩과 등의 것에서 높았다. 기생 유도 실험을 통해 미국실새삼은 1종을 제외한 모든 식물에 기생할 수 있음이 확인됨으로 써 이 침입식물의 분포의 제한 요인은 분산과정이라는 것을 알 수 있었다. 기주식물의 감염된 부위는 줄기와 잎 두 곳에서 대부분 나타났고, 드물게 잎이나 줄기에만 나타나기도 하였다. 이 연구로 12개 과의 기숙식물 45종(12개 과의 초본식물 33종과 목본식물 12종)을 새롭게 추가하였다. 그 중에는 조와 같은 농작물뿐만 아니라 멸종위기야생식물 6종에도 기생하였고, 특히 후자의 경우에는 미국실새삼의 기생으로 식물체가 고사까지 당하는 경우도 있었다. 이는 미국실새삼이 잠재적으로 야생식물에게도 확산될 가능성이 높다는 것을 의미한다.

This study aimed to investigate the perception and preferences related to Korean food according to the ethnicity of university students in Yanbian, China. Korean food was preferred by Korean-Chinese as compared with Chinese students, and Korean-Chinese students preferred Korean food more than Chinese food. Both Korean-Chinese and Chinese preferred Korean food more than traditional Chosun food. More Korean-Chinese than Chinese students had positive perceptions of Korean food, which included foods made with jang, kimchi smell, and healthiness due to diversity. For evaluation of Korean food taste, more Chinese than Korean-Chinese subjects thought Korean food is not greasy and hoped salty taste. Both awareness and preferences related to Korean food were significantly higher in Korean-Chinese than Chinese students. Meat foods (so-galbi, dak-galbi, jang-jorim) were relatively high in terms of preference in both Korean-Chinese and Chinese students. Moreover, Chinese students preferred Korean traditional foods (sujeonggwa, yakgwa, gangjeong). In Korean- Chinese students, Korean representative traditional foods (kimchi, jangajji) and Korean traditional holiday foods (tteokguk, mandu-guk) were relatively low in terms of preference. This study found that the traditional food culture of Korean-Chinese has been maintained in Yanbian, whereas there is a change in the young generation.

This study aimed to investigate the perception and preferences related to Korean food of university students in Yanbian, China. Self-administered questionnaires were collected from 306 (124 males and 182 females) students. The preferences for Chinese food (44.7%) and a combination of Korean (32.0%) and Chosun food (12.4%) were similar, and Korean food was more preferred than traditional Chosun food. The main reason for preferences for Korean food was taste. The perception of Korean hot spices and kimchi smell was not good, whereas positive perceptions where held for foods made with jang, new Korean food experience and healthiness of Korean food. Awareness of Korean food was in the order of bibimbap, kimchibokkeum- bap, gimbap, baechi-kimchi and ttoe-bbokki. Preference order was bulgogi, so-galbi, jang-jorim, dak-galbi and dewaeji-galbil. Meat foods and Korean traditional foods were relatively high, whereas kimchi, ttoe-bbokki and bibimbap were relatively low in terms of preference. More female than male students preferred Korean food, and the perception of new food experience and healthiness of Korean food were positive. Moreover, both awareness and preference related to Korean food were significantly higher in female than male students. These results can be used as a foundation to prepare a localization strategy of Korean food to China.

식량 부족 문제가 대두되고 있는 요즘 하나의 해결 방안으로 곤충 사업이 크게 주목받고 있다. 곤충이 미래 식량으로 주목받는 이유는 짧은 시간 안에 대량사육이 가능 하며, 인수공통전염병이 없으므로, 질병, 전염병 우려에서 비교적 자유로우며 사육으로 인한 환경 파괴가 적다는 장점을 가지고 있다. 또한, 식용곤충을 사육하는 농가는 8백 곳으로, 1년 만에 5배 넘게 늘었으며 농촌진흥청은 곤충산업 규모가 2020년 2조~3조 원에 이를 것으로 전망했다. 이렇게 커져가는 식용 곤충 산업에 대해 사람들의 곤충에 대한 인식과 선호도를 알아볼 필요성을 느껴 설문을 실시하였다. 설문조사는 10대부터 40대 이상의 연령층을 조사하여 다양한 연령의 선호도에 대해 조사하였고 유년기 시절 지역을 조사하여 지역에 따른 곤충의 선호도 정도를 조사하였다. 온라인 400명 오프라인 400명으로 표본 집단의 크기를 충분히 하였다. 해당 설문 조사에서는 유년기 지역보다는 성별로 식용 곤충 섭취 경험이 나뉘어 졌다. 향후 식용 곤충 섭취에 대해서는 부정적인 응답이 많았지만 가공된 식품으로 대중화 한다면 긍정적인 방향으로 나아갈 것으로 판단한다.
