곤충은 지구상의 생물 중에서 가장 많은 종을 차지하고 있다. 또 인류보다도 훨씬 오래 된 지구의 선점자이며, 환경에 대한 적응력이 뛰어나 전 세계적으로 서식하고 있다. 현대 에 접어들면서 곤충은 사람들에게 식품(식용 곤충), 치유(소리, 정서곤충) 등의 다양한 효 과를 제공하고 있지만, 사람들은 그 효과에 대해서 잘 알지 못하고 징그럽다고 생각하는 것이 대부분이다. 그래서 우리는 곤충 중에서도 울음소리로 사람들의 마음을 치유하는 소 리곤충(귀뚜라미, 여치)를 주제로 본 연구를 하였다. 본 연구는 무작위의 성인 30명을 대 상으로 소리곤충(귀뚜라미, 여치)에 대한 인지 정도를 알아보고 실제 성인들이 소리곤충 (귀뚜라미, 여치) 울음소리의 효능에 대해서 알고 있는지, 알지 못한다면 그 효능에 대해 서 알리기 위한 것이 목적이다. 이에, 본 연구를 위하여 설문지 법을 사용하였으며, 대상 자는 무작위 대상의 남녀 30명(여:18, 남:12) 이었다. 설문조사 결과로는 응답자의 과반 수가 소리곤충 울음소리에 대해서 긍정적인 답변을 보였다. 하지만 소리의 호감도에 비해 직접 소리곤충을 키울 의향이 있다는 사람은 5명(20%)밖에 되지 않았다. 이에 성인들을 대상으로 귀뚜라미나 여치 등을 키우는 체험이 활성화된다면 더욱 긍정적인 결과가 나올 것으로 판단한다.

Recently, halogen lamps for vehicle exterior lamp systems are being replaced by LEDs (Light Emitting Diode) in consideration of miniaturization, power consumption, life, luminance, and eco-friendliness. Due to regulations on the amount of light required, luminance, light uniformity, and glare prevention, it is required to develop a light guide for controlling a light source of an LED lamp for a vehicle. For the development of the light guides, the development of machining technology that can cut micro patterns of hundreds of micrometers scale into surface roughness of tens of nanometers scale must be preceded. In this study, the effect of variations in cutting conditions on surface roughness was analyzed through experiments. The micro patterns was manufactured by cutting into STAVAX material, and the surface of the micro patterns was super-finished using a ball-shaped PCD (polycrystalline diamond) tool without flutes. In experiments, the cutting conditions of the super-finishing process were varied, and the varied cutting conditions were feed rate, radial depth of cut, and spindle speed

Society’s emphasis on a thin body ideal may intensify an individual’s negative perceptions of fatness. The purpose of the present study was to examine the relationship between sociocultural attitudes toward appearance (awareness and internalization of the female ideal) and anti-fat attitudes among middle-aged Korean women. In addition, the aim was to examine whether the body internalization of female ideals was a mediator in the proposed model. Participants included a sample of 264 middle-aged Korean women who completed a series of measures online. The following information was collected through online questionnaires: awareness and internalization of the female ideal, attitudes toward fat, body weight perception, and demographics. Data were analyzed using correlation analysis, descriptive analysis, factor analysis, and structural equation modeling. The measurement model and the structural model testing provided an acceptable fit to the data, and all proposed pathways in the research model were statistically significant. Awareness of the female ideal was significantly and positively associated with internalization, and it significantly and positively predicted both constructs of anti-fat attitudes. Additionally, awareness of the female ideal was significantly and positively indirectly associated with attitudes toward fat peopledislike and willpower mediated by internalization. Overall, these findings suggest that society’s emphasis on female appearance and a thin body can ultimately result in significant stigmatization of overweight/obese individuals. This study emphasizes the importance of establishing a healthy appearance standard to reduce anti-fat prejudice.

Fashion companies and brands’ marketing activities focus on resolving environmental problems; however, these companies’ efforts, there are some examples of so-called “greenwashing”. This paper aims to analyze different perceptions of brand authenticity, green marketing, and purchase intention toward the brand before and after exposure to case information about greenwashing. A total of 211 data were gathered and analyzed using SPSS 25.0. Respondents were asked to respond to same questionnaires related to green marketing and the brand authenticity before and after their exposure to greenwashing information. The study participants’ perceptions of green marketing from the brand were statistically significantly negatively changed after exposure compared to before exposure. Similar patterns in results were found in the context of consumers’ perception of brand authenticity (genuineness, originality, and consistency), and purchase intention. The originality of this study is in evaluating consumers’ perception of greenwashing focused on brand authenticity. The findings of the study suggest that if a fashion brand’s green marketing activity is perceived as greenwashing by consumers, the perceptions of green marketing, brand authenticity, and purchase intention can all decline. It is suggested that fashion brands need to develop a sincere and truthful green marketing campaigns to keep and enhance their brand authenticity.

The objectives of this study were: (1) to identify differences in consumer attitudes and intentions to recycle fashion products using three types of recycling (including resale, reform, and donation), and (2) to examine the moderating effects of consumer prosocialness on the relationships between attitude and intention for each type of fashion product recycling. Men and women aged 20 years and over were recruited from a marketing research firm panel. Participants completed an online questionnaire incorporating measures for attitudes and intentions to resale, reform, and donate fashion products, prosocialness, frequency of purchasing fashion products, monthly amount of spending on fashion products, and demographic information. Data from 224 participants were analyzed using SPSS 25.0 and PROCESS macro. The results demonstrated that consumers had significantly different attitudes and intentions depending on type of fashion product recycling. Consumers had more positive attitudes toward donation compared to resale and reform types of recycling. Consumer intentions toward resale and donation were significantly higher than their intention to reform. Furthermore, this study confirmed that the attitude-intention gap in fashion product recycling can be explained by individual prosocialness. The moderating effects of prosocialness on the associations between attitude and intention to recycle were significant. The implications of increasing consumers’ behavior intention to recycle fashion products was discussed and future research suggestions are provided.

The Internet of Things (IoT) has gained enormous popularity in various fields of industry. An IoT shopping environment is considered an effective tool for convenient use by consumers. Perceived values (including convenience and privacy risks) of IoT shopping can be the main factors that influence consumers’ shopping intentions. The current study proposed a research model based on a value-based adoption model, which integrated perceived benefit and sacrifice, shopping attitude, and shopping intention in an IoT shopping environment. As potential customers, participants in their 20s and 30s were recruited through a marketing research firm. Responses collected via an online questionnaire validated the proposed research model and hypothesis. The results confirmed significant, positive relationships between perceived benefit, including both remote control and access convenience, and consumers’ positive attitudes toward IoT shopping. The association between perceived privacy risk and consumers’ shopping attitudes was not significant. The indirect effects of two benefits of IoT shopping on shopping intention were also significant and positive. From a practical perspective, this study can help marketers and service providers manage their IoT shopping platforms or applications more effectively to attract consumers. The implications and limitations of this study are discussed. Directions for future research and development of IoT shopping environment are suggested.

Consumers want to express their original unique personality, and even are willing to endure high expenses in order to do this. One noticeable strategy in the market, used by companies to suit for this consumer sentiment, is that of employing limited edition marketing and limited free gifts. This study investigated the effects of limited free gifts on consumer response. Specifically, the present study examined how the need for uniqueness moderated the effects of limited free gifts on brand commitment and attitudes. The online survey method was used to gather the data and a total of 224 data were used to analyze data. The results of the research were as follows. The findings revealed four dimensions of limited free gifts: scarcity/specialty, not for sale, complementarity, and risk. Complementarity positively affected brand commitment, while all four dimensions of limited free gifts positively influenced brand attitude. In addition, the need for uniqueness was proven to be the strongest variable which positively influenced brand commitment and attitudes. Also, when the need for uniqueness was applied as a moderating variable, depending on the levels of the need for uniqueness, the effects of riskiness on the consumer’s response were shown to be different. The findings of this study infer various academic and practical applications.

The present study investigated fashion Instagram marketing, applying the concept of gamification. It set out to examine the following specific issues: 1) perceptions of flow, pleasures, dimensions of game dynamics (challenge, competition, achievement, reward, relationships among participants, and relationships between brands and consumers), and consumer responses based on frequency and involvement in exercise; 2) the effects of game dynamics dimensions on flow and pleasure; and 3) the effects of flow and pleasure on consumer responses. An online survey was used to gather data and the study analyzed a total of 200 responses. The results of the study were as follows. Perception differences were found only in relation to exercise involvement. Competition, relationships among participants, and relationships between brands and customers positively predicted flow. Among the dimensions of game dynamics, challenge, competition, reward, relationships among participants, and relationships between brands and consumers positively influenced pleasure. In addition, the study also found that pleasure and flow had positive effects on intention to participate and brand loyalty. Meanwhile, only pleasure predicted word-of-mouth. These findings suggest that fashion brands implementing Instagram as a marketing channel should seek to stimulate pleasure and fun to provoke positive consumer responses. Furthermore, the findings of the study provide practical and useful insights for fashion brands implementing Instagram marketing.

This study investigated how the image congruity of social commerce and fashion brand types affects purchase intention and how trust and price sensitivity moderate this relationship. National brands, private brands, and non-brands were used as brand types in the present study. The online survey method was used to gather the data, and 232 data samples were analyzed. The results of the research were as follows. Consumers perceived greater image congruity between social commerce and nonbrands, followed by private brands and national brands. The significant perception differences were examined by comparing the mean values. There was a significant positive effect of image congruity of social commerce and non-brands on purchase intention. However, insignificant effects were found for image congruity between social commerce and private brands and national brands. In addition, trust and price sensitivity positively predicted social commerce purchase intention. A significant moderating effect of trust was found on the relationship between purchase intention and image congruity of social commerce and non-brands. A moderating effect of price sensitivity was found on the relationship between purchase intention and image congruity of social commerce and private brands. The findings of the present study offer valuable insights into social commerce concerning implementing diverse fashion brands as well as academic and practical implications.

Digital signage in a smart store would engage and invoke responses from consumers because good in-store experiences are more important than ever. Thus, the present study investigates consumer perceptions of interactive digital signage integrating technology acceptance model. Specifically, the current study examined 1) the effects of personal and fashion innovativeness on interactivity; 2) the effect of interactivity on perceived usefulness, ease of use, and enjoyment; and 3) the effects of perceived usefulness, ease of use, and enjoyment on intentions to use the products and the store, visit the store, and engage in word-of-mouth. As a pre-study, two researchers visited the smart stores of six brands in Seoul, all of which integrate various technologies in the fashion field. A video clip was developed as a stimulus to the study. A total of 214 responses were gathered and analyzed. The results were as follows. Personal innovativeness has a significantly positive effect on interactivity, whereas fashion innovativeness has no significant effect. Interactivity had positive effects on the perceived usefulness, ease of use, and enjoyment. Consumer responses (i.e., intentions to use, visit, and engage in word-of-mouth) were predicted by usefulness and enjoyment, but not by ease of use. The findings of this study could provide the fashion industry and retailers practical and valuable insights into enhancing consumers’ in-store experiences through the use of interactive digital signage.

The study aims to investigate the effects of media and self-image congruity of ideal body image on the dieting and exercising behaviors of Korean and U.S. female college students. This study focuses on the concept of self-image congruity in order to examine how respondents perceive actual and desired self-images compared to an ideal female body image selected by respondents. A self-administered survey was conducted, resulting in 331 total responses (194 from Korean students and 137 from U.S. students). The data were analyzed through descriptive analysis, t-test, exploratory factor analysis, and regression analysis using SPSS 23.0. The findings revealed significant differences between Korean and U.S. female college students. U.S. students were more exposed to body image ideals in the media than Korean students; however, Korean female students valued the information regarding ideal body image conveyed by the media more than U.S. respondents. Among Korean female students, exposure to media messages regarding ideal body image and media importance had significant effects on desired self-image congruity, while these factors were not significant among U.S. students. However, there was a negative effect of media exposure on actual self-image congruity among U.S. respondents only. Additionally, the study uncovered that Korean students manage their body image through dieting behaviors while U.S. respondents manage body image through exercise behaviors (weight training as well as cardiovascular exercise). The study provides further support for self-image congruity, which extends its applications to the body image field.

Recently, some fashion retailers have initiated sustainable actions in the form of corporate social responsibility (CSR) activities to address consumers’ social concerns. This study intends to combine the concept of CSR motivation attributions with brand extension literature in order to examine how consumers’ trust of a parent brand affects their CSR motivation attributions and ultimately their attitudes towards parent-brand CSR activities and sustainable extension lines. A self-administered online survey was conducted using scenarios describing a fast fashion retailer introducing a sustainable line. Data from 303 female U.S. consumers, aged between 18 and 34 years, were used for the statistical analysis. Data analyses were conducted using SPSS 21.0 for descriptive analysis, exploratory factor analysis, and regression analysis. The results revealed that all hypotheses were supported. The findings show that consumers’ trust of a parent brand has an indirect impact on positive attitudes towards the parent brand’s CSR activities as well as the sustainable extension product line, mediating positive evaluations of the brand’s social CSR motivations. In addition, this study suggests consumers’ prior trust of the parent brand is a variable that affects consumers’ evaluation of CSR motivation sincerity. Marketing suggestions and thoughts based on the findings of this study were provided.

Mechanical Biological Treatment (MBT), widely spread in Europe, is a process combined with mechanical separation and biological treatment. This is an alternative technology that can accomplish WtE (Waste-to-Energy) and landfill diversion. Bio-drying, aimed to produce high quality SRF, focused on removing moisture of waste through generated heat when biodegradable organic material is partially degraded by micro-organism. However, most of SRF production facilities in Korea consist of mechanical treatment. In those, 40% of input waste have been generated as residue disposed of in landfill. As a result of physico-chemical characteristic analysis of residue from target facilities, composition of food wastes, papers and plastics ranged 6.7 ~ 18.3%, 9.1 ~ 17.3%, and 5.8 ~ 12.2%, respectively. The moisture content of residue was about 43%, and low heating value was analyzed a range of 1,300 up to 1,900 kcal/kg. Results showed that combustible material having potential to produce SRF is discarded and the amount of biodegradable material such as food waste is still large. Therefore, we assumed it may cause pollution in terms of landfill gas emission and high concentrated leachate generation. In this study, recent trends of Bio-drying is discussed as the alternative technology to solve problems at SRF production facilities in South Korea.

This study was carried out in order to determine the biological activities such as antioxidant activities in nine cultivars of Momordica charantia L. (Korea, China, Japan and Philippine native cultivars). Their antioxidant activities were measured using DPPH free radical scavenging, ABTS cation radical scavenging, and Nitrite scavenging ability. The highest total polyphenol content (16.82 μg/ml) measured in the native Korea cultivar, and this value was 4.0 μg/ml higher than that of the 'Verde Beuhas' cultivar (12.82 μg/ml). The 'Peacock' cultivar had the highest total flavonoid amount which was 4.38 μg/ml. The free radical scavenging activity using DPPH method was the highest in the native China cultivar (RC50 = 102.6 μg/ml). ABTS cation radical scavenging activity according to cultivars was significantly higher in 'Peacock'. Nitrite scavenging ability showed the most remarkable effect at the pH 1.2, exhibited to 81.5~86.9% by addition of ethanol extract 1μg/ml from Momordica charantia L. These results suggest that Momordica charantia L. had the potent biological activities, and that their activities exhibited differently depending on cultivars.

Some studies of dandelion have been carried out on bioactivities, however, no comparative analysis on antioxidant and cytotoxic activities in the Korean dandelion (T. coreanum NAKAI.; KD) and dandelion (T. officinale WEB.) have been reported. In this study, the extracts of KD and dandelion analyzed relative phenolic contents and free radical scavenging, antioxidant enzyme and cytotoxic activities. The extract of Korean dandelion leaves (KDL) exhibited a higher phenolics content (368±11.5 mg/l00 g) and a strong free radical scavenging activity (RC50value;87.89 ug/ml) than other parts and BHT (120.12 ug/ml), synthetic antioxidant. At ascorbate peroxidase (APX) activity, the dandelion root (DR) had a greater (38.8 U/mg protein) antioxidant enzyme compare to the dandelion leaves (12.2 U/mg protein). The catalase (CAT) and superoxide dismutase (SOD) followed higher enzyme activity in Korean dandelion root (KDR) than other parts. In a cytotoxic activity against human cancer cell, the extracts of KDR was found to be active against Calu-6, HCT-116, and SNU-601 cell lines, with IC50 values of 522.34, 532.74 and 614.85 ug/ml, respectively. These results suggest that KD and dandelion would be an alternative antioxidant source, based on natural plant resources.

한국의 전통적인 민간 약재로 사용되어져온 흰민들레의 잎절편체로 부터 기관형성을 통한 재분화를 시도하였다. 잎 절편체를 BA (0-4mg/L)와 2,4-D (0-1mg/L)가 혼합 첨가된 MS 기본 배지에 치상하여 배양한 결과, 배양 3주후부터 신초가 발생되었다. 신초 분화율은 2mg/L BA 첨가된 조건에서 가장 높았으며, 배양 4주째 4mg/L BA 첨가된 조건에서는 캘러스가 유기되었다. 잎령에 따른 부정아 형성율, 발생빈도, 건량, 생중량을 조사한 결과, 발아 후 7주된 잎 절편체에서 평균 11.5개의 신초를 형성하였다. 유도된 신초는 0.5mg/L NAA가 첨가된 배지에서 발근되었으며, 화분에 옮겨 완전한 식물체로 재분화 되었다.

여주의 부위별 항산화 활성 및 비타민 C의 함량을 조사하였다. 각 부위별 비타민 C의 함량을 보면 미성숙과에서 92.2mg/100 g으로 가장 높게 나타났는데, 이는 줄기에서의 2.5mg/100 g 보다 40배 이상 높은 함량이다. 여주의 각 부위별 메탄올 추출물을 TBA 방법으로 항산화효과를 측정한 결과 잎 추출물에서 0,05로 가장 높은 항산화 효능을 나타냈으며, 이는 추출물이 ascorbic acid와 BHT보다도 항산화력이 우수함을 알 수 있었다. 또한 각 부위별 건조시료와 생체시료에서의 SOD, APX 그리고 CAT의 활성을 비교한 결과 건조시료인 경우가 생체시료에서보다 활성이 더 높게 나타났다. 이러한 결과들은 여주가 식물유래 천연 항산화제로서의 높은 가치를 지니고 있으며 앞으로 이에 대한 개발 가능성이 매우 높음을 시사해 주고 있다.

본 연구에서는 탱자의 미성숙배로부터 캘러스 유도와 재분화에 관하여 연구하였다. 탱자 배발생 캘러스들은 3% sucrose와 44.4 μm BA로 처리된 ½MS배지에서 광조사(2,000 1x, 16h)시에 미성숙종자의 배로부터 유도되었으며 식물체 재분화는 MS배지에 5.0 μm BA를 첨가하였을 때 가장 양호하였다. 탱자는 배양2~3주경에 담황색의 캘러스가 유도되었으며 배양5~6주경부터는 딱딱한 녹색의 캘러스로 변하였다. 기내 재분화는 3% sucrose와 5.0 μm BA가 첨가된 MS배지에서 배발생 캘러스로부터 직접 유도되었다. 또한 배양 12주 후에 Multishoot가 재분화되었으며, 배양 16주 후에 뿌리가 형성되었다. 또한 뿌리가 형성된 식물체들은 토양으로 옮겨져 완전한 식물체로 잘 자랐다. 광학 현미경 관찰시 탱자에서는 배양4주경에 하얀색의 조밀한 배양된 세포들이 나타났다. 배양6주경부터는 세포들이 신장되면서 배발생 돌기가 나타났으며 주변의 세포들은 액포화 되었다. 또한 배양12주경에는 미성숙 잎에서 발달된 유낭과 전형성층을 관찰하였다.
