This purpose of this study is to analyze the pursuit of current fashion trends and fashion image types of middle-aged women in Korea. This study attempted to investigate the standards and properties of these different types of fashion images. The overall characteristics of middle-aged women and the concepts of personal image and fashion image were investigated through literature research. Survey and analysis based on Q methodology was conducted. Factors of personal image, fashion image and components of fashion image were analyzed by collecting information from in-depth workshops and focus group interview of an expert group. The results of this study are as follows: 1) The main factors influencing the current fashion image of women in their forties and fifties in Korea are classified into six types. 2) The elements of fashion image that Korean women in their 40s and 50s pursue are divide into four types. 3) Each type can be recognized by specific fashion image components and colors. 4) This shows that middle-aged Korean women are highly conscious of how others perceive them and have a desire to not stand out from others. It also shows that they are very active in pursuing fashion and following trends, which is the image of an active and dignified woman. This study provides the framework that enables sorting of the fashion images types that middle-aged Korean women want to pursue. The results from analyzing the factors can be used to recognize specific fashion images, and can be used in the planning and designing of fashion items for middle-aged Korean women.

Small-scale household digesters have been promoted across Asia as a sustainable way of handling manure. The major advantages are that they produce biogas and reduce odor. However their disadvantages include the low recycling of nutrients, because digestate is dilute and therefore difficult to transport, and the loss of biogas as a result of cracks and the intentional release of excess biogas. In this study, life cycle assessment (LCA) methodology was used to assess the environmental impacts associated with biogas digesters in Vietnam. Handling 1,000 kg of liquid manure and 100 kg of solid manure in a system with a biogas digester reduced the impact potential from 4.4 kg carbon dioxide ($CO_2$) equivalents to 3.2 kg $CO_2$ equivalents compared with traditional manure management. However, this advantage could easily be compromised if digester construction is considered in the LCA or in situations where there is an excess of biogas which is intentionally released. A sensitivity analysis showed that biogas digesters could be a means of reducing global warming if methane emissions can be kept low. In terms of eutrophication, farms with biogas digesters had 3 to 4 times greater impacts. In order to make biogas digesters sustainable, methods for recycling digestates are urgently required.

The purpose of the study was to divide social commerce websites' information into components of product, price, service, and seller information, and to systematically analyze each component of information. A content analysis was used as a research methodology, and 100 webpages from social commerce websites were analyzed. As results, the social commerce websites provided basic information (front view, fabric contents, country of origin, care, color, size) for product information and emphasized price information, including discount rates, sales dues, product quantity, and the amount of products sold. They basically provided expected delivery date, delivery company, Q&A, and return/refund service for service information. In addition, they basically presented brand logo and brand name but need to add information about brand concepts, history and volume as seller information. This study suggested diverse theoretical and practical implications of social commerce information.

Objectives : This study uses meta-analysis methodology to examine the statistical consistency and importance of random variation among results of epidemiologic studies of occupational electromagnetic field exposure and leukemia. Methods : Studies for this meta-analysis were identified from previous reviews and by asking researcher active in this field for recommendations. Overall, 27 studies of occupational electromagnetic field exposures and leukemia were reviewed. A variety of meta-analysis statistical methods have been used to assess combined effects, to identify heterogeneity, and to provide a single summary risk estimate based on a set of simiar epidemiologic studies. In this study, classification of exposure metircs on occupational epidemiologic studies are reported for (1) job classification (20 individual studies); (2) leukemia subtypes (13 individual studies); and (3) country (27 individual studies). Results : Results of this study, an inverse-variance weighted pooling of all the data leads to a small but significant elevation in risk of f 1% (OR=1.11, 95% CI : $1.06\sim1.16$) among 27 occupational epidemiologic studies. Publication bias was assessed by the 'fail-safe n' that may be not influence for all combined results exception a few categories, ie, 'power station operators' and 'electric utility workers' by job classification on occupational study. And ail combined odds ratio results were similar for fixed-effects models and random-effects models, with slightly higher risk estimates for the random-effects model in situations where there was significant heterogeneity, ie, Q-statistic significant (p<.05). Conclusions : We found a small elevation in risk of leukemia, but the ubiquitous nature of exposure to electromagnetic fields from workplace makes even a weak association a public health issue of substantial power to influence the present overall conclusion about relationship between electromagnetic fields exposure and leukemia.

The purpose of this study is to define the tastes of middle-aged Korean men by analyzing their characteristics, such as self-image, and fashion style. This study was carried out by using the Q methodology for survey research. The results of this study are as follows; First, the self-images of middle-aged men were classified into 'comfortable, calm, neat, and gentle,' 'realistic, active, sociable, and familiar,' 'sensible, emotional, romantic, and rational,' 'refined, emotional, luxurious, and sophisticated,' and 'aggressive, sensible, realistic, and rational.' Second, by analyzing the congruity of clothing form, fashion accessory, and fashion color types, this study was classified into the following 10 fashion styles: 'modern classic,' 'sophisticated,' 'town casual,' 'traditional casual,' 'comfortable,' 'chic casual,' 'contemporary,' 'gentle classic,' 'classic sporty,' and 'soft classic.' Third, this study analyzed the self-images and fashion styles of the men, and produced the following personal tastes of middle-aged men: 'success-oriented,' 'ability possession,' 'internal stability-oriented,' 'freedom-oriented,' 'self-satisfaction,' 'individuality compromise,' 'emotional release,' 'stability-oriented,' 'practicability-oriented,' and 'youth effort' types. By combining those types with social dimensions, this study produced the following tastes of middle-aged men: 'stabilized traditions,' 'achievements with high sociality,' 'youthful individuality,' 'active self-realization,' and 'realistic, logical pursuit.' The results of this study can be used as a meaningful data for developing the marketing strategy, which reflects the middle-aged men's changed tastes.

Purpose Among various psychosocial factors, negative social comparison, attention blocking to stimuli, and cognitive interference via information overload are considered most critical in hindering the effective performance improvement of computer-based idea generation. Given that the effect of negative social comparison along with a plausible solution based on the notion of performance feedback and goal setting has been successfully addressed, this study focused on the remaining issues of "attention blocking to stimuli and cognitive interference via information overload" and attempted to find a way to alleviate the effect of such process losses on performance. Design/methodology/approach A 2 × 4 between-subjects design was used, crossing cognitive ability (high and low) and personality (extroversion and introversion). Five subjects per each treatment were randomly selected to make the sample size equal. The group simulator was used to measure individual-level performance. The dependent variables were the quantity of and quality score of ideas. The manner by which these performance measures were operationalized was consistent with prior studies. An additional analysis using the number of diverse ideas was also conducted. Findings Three arguments were made in this study: (1) high cognitive individuals would perform better than low cognitive individuals, (2) extraverted individuals would perform better than introverted individuals, and (3) cognitive ability and personality would interact such that individuals in Q1 would have the highest performance. Cognitive ability had an effect on quality not quantity. Personality had an effect on both quantity and quality. An interaction between cognitive ability and personality was not found due to small sample size despite the use of the group simulator.

The purpose of this study is to find out the operant factors, or types of skin care, and, more importantly, to propose the intervention for more effective skin care and marketing strategies in this business. That is the main reason that the study employes Q methodology which measures human subjectivity objectively and scientifically. This study finally revealed three distinctive factors : Type I, The Passive Follower, Type II, The Active Needs, and Type III, The Independent Judgment. The first type includes people who show passive recognition. They want to be put in charge of experts in the skin care center and to buy cosmetics recommended by experts, and are deep interest in the reaction of other people. The second type contains people who desire things actively. To live delightfully and fashionably, they think of the necessity of skin and body care as an important thing, and feel that it is necessary to take care of the skin beauty actively and regularly for the aging resistance. The third type includes people who judge independently. In general, they recognize and desire the necessity of the skin care, but they think of the skin care as a part of the health care more widely rather than a special thing. These three types are not fixed, but continuously changed in the accordance with the condition and interaction with the circumstance, the results will be utilized as basic materials for the skin and health care through the application according to the characteristic of each type they belong.

Nutrigenomics refers to research that investigates the interaction between nutrition and the human genome. Caffeine in tea and coffee is widely and routinely consumed by people. This study was performed to confirm the effect of caffeine treatment on the gene expression and cytokine profiling in 3T3-L1 adipocyte cells using microarray and protein array methodology. Treatment of caffeine in 3T3-L1 adipocyte cells increased expression of several genes related with obesity including adipocyte C1Q and collagen domain containing (ACDC), Adipsin (ADN), uncoupling protein 3(UCP3), while glyceraldehyde-3-phosphate dehydrogenase (GAPDH), which is known as lipid storage enzyme, was decreased by caffeine treatment. Furthermore, cytokines, such as interleukin-3 (IL-3), interleukin-12(IL-12), interleukin-13 (IL-13), granulocyte colony stimulating factor (GCSF), granulocyte macrophage colony stimulating factor (GM-CSF) and vascular endothelial growth factor (VEGF), were decreased in caffeine treated 3T3-L1 adipocyte cells. These results provided interesting information about the genes related with caffeine and cytokine expression profiling in obesity.

Distribution channel decisions involve long-term commitments with other firms that are very difficult to change or replace. In particular, marketing channel decisions in emerging markets are much more complicated due to unfamiliar conditions and problems such as lack of market data and distribution systems. Therefore, when a company considers changing or introducing a marketing channel in an area, it is much more difficult to judge its effectiveness in an emerging market than in a developed market. In this study, we investigate the development process of a new direct marketing channel of Hongfu Fertilizer Company (hereafter Hongfu), a medium-sized Chinese fertilizer manufacturer, and propose an approach to test the feasibility of this new marketing channel in the Chinese rural market. We measure the effectiveness of Hongfu's new marketing channel from two perspectives: i) from customers' perspective through direct responses of farmers, which showed that a new channel can increase the convenience and lower the purchasing costs for the farmers, and ii) from the company's perspective, by calculating the incremental profit of the company using the expansion factor (T/Q) method, which suggested that the execution of Hongfu's strategy to expand a new marketing channel will result in an increase in profits. The results of this study contribute to the development of a methodology to test the feasibility of a new direct marketing channel in the emerging markets such as the Chinese rural market. Traditional and indirect distribution channels in emerging markets are generally not very efficient and difficult to change. Especially, in emerging markets, like the Chinese rural market, the methods of testing channel feasibility must be different from that of developed markets. Considering market situations, market experiments can be more effective then systematic market surveys in testing channel feasibility in emerging markets. This study implies that managers must learn to cope with a transition from the traditional marketing channels in emerging markets. With the development in farmers' understanding of marketing concept, the transition from traditional marketing channel is unavoidable for all firms. Farmers in China are generally very conservative, however, their buying behaviors are changing. Therefore, fertilizer companies should try to adjust in accordance with farmers' demand characteristics that the efforts to meet the economic needs of farmers with new marketing channels as well as trust building are critical in the near future.
