This study evaluated the perception, consumption behavior, and optional attributes of Korean, Chinese, and U.S. consumers of energy bar products. Data were compared and analyzed by surveying 300 consumers in each country. Significant differences were observed in preference for energy bars according to their nationality, in the order China, the U.S., and Korea. Perception of taste, types and dietary suitability of the products ranked lower for Korean consumers, as compared to consumers of the United States and China. The order dietary fiber, protein, and calcium were the sought-after nutritional requirements of the products. The demand for protein was significantly higher in the U.S. Calcium demand was low in the United States and China, but was very high in Korea, which could be attributed to the low calcium intake of Koreans. Other optional attributes which were closely associated with the purchase and re-purchase decision, included price, taste and delivery period. All three factors were recognized as important options in Korea, whereas awareness of packaging/appearance and brand was not. The taste, nutrients and price in the U.S. ranked high as important optional attributes, while the packaging, external and expiration dates were recognized as low. Unlike Korea and the U.S., important optional attributes for Chinese consumers were determined in the order expiration date, taste, and nutrients, and showed low perception for packaging, appearance, weight, counts, and prices. Evaluating the preference for the main and secondary ingredients, Koreans preferred nuts over grains, Americans preferred dried fruits over nuts, and Chinese preferred nuts and grains; both Korean and American consumers had low preference for dried vegetables. The preference for chocolate was low in Korea and China, whereas preference for jelly was high in China as compared to Korea and the U.S. The intention of purchasing energy bars was significantly lower in Korea than in the U.S. and China. A variety of nutritious functional bars have recently been distributed and sold in Korea, but they are mostly produced in the U.S., which is the largest producer and consumer worldwide. Taken together, results of this study indicate that the demand for nutritional enhancement and preferred materials vary according to the nationality. Hence, it is necessary to develop products that reflect these criteria. Further research is required to analyze the relationship between preference and consumption behavior for each material product developed in the future.

Elderly population has increased rapidly and adjusting the environment is in demand to support their health. To improve the living environment of elderly, an appropriate plan for customized home modification is needed upon the personal contexts. The purpose of this study is to explain the sequence and to build an insight on customized home modification for vulnerable single elderly. It is a case study based on single target that includes 6 months of execution period deeply seeking the appropriate plan for implementation. The target is a male elderly aged 74 living in a single story detached house. The various research methods are applied in this study including exploratory, participatory, action and trade-off preference researches. The result shows that plan for home modification is complex outcome of interlocking uniqueness between residence environment and resident situation. If customized modification is targeted for residentially vulnerable social group, more sensitive approach aiming for the highest result is required due to financial constraint. To conclude, comprehensive understanding of overall circumstances of a dwelling, a resident and various stakeholder is essential throughout the process. Since the aging-in-place of elderly cannot be achieved without self-sustaining living environment, customized home modification should be a tool to meet housing suitability. It is important to strengthen the experts and future workforce with networks of local residents to share opinions and appropriate plans.

The purpose of this study is to identify the design features appropriate for the altered physical characteristics of pregnant women and formulate the direction of future design and development of maternity wear. A Delphi research method based on a panel of experts and pregnant women was used and the survey was conducted to determine the suitability of maternity wear. The survey found that A-line silhouette outerwear with round necklines, with wide sleeves and snap-button fastening on the front with a formal and decent look was considered appropriate as maternity and postpartum wear. Shirts and blouses long enough to cover the hip area to complement women's curvy and full figures, especially around the bust, waist, and hip areas during the later stages of pregnancy were found to be appropriate. Calf-length pleated skirts were comfortable to wear during pregnancy due to the abundant freedom of movement and space offered by pleats. Ankle-length straight leg pants were rated appropriate in terms of comfort and style both during late stages of pregnancy and at work postpartum. Dresses decorated with pleats from the armholes all the way down to the knees were found to provide high levels of comfort at the abdomen, chest, and hips, and considered appropriate. Based on this study results, a follow-up study will be conducted to examine the design of maternity wear during pregnancy as well as at work after pregnancy.

Kimchi is the most well-known Korean traditional food, but it is also the main leftover of school lunch and dinner menus. This study aimed to familiarize teenagers with kimchi through school meals and to increase their daily kimchi intake, ultimately by appealing to the young generation's taste. A questionnaire survey was conducted in the Ansan area to examine student's acceptability of kimchi and their attitudes toward kimchi. Approximately 65% of males and 67% of female students liked the moderately fermented and pungent taste of kimchi. Kimchi served in school meals was regarded as nutritional but cheap. Approximately 72% of male and 82% of female students responded that they liked menu items using kimchi. Approximately 48% of students responded that menu items using kimchi in schools are not diverse. Students preferred meat as an ingredient in kimchi. The preferred cooking methods were stir-frying and frying, whereas boiling was the least favorite. Based on the survey results, ten kimchi menu items had been developed. The suitability of the menu was evaluated by students and cooks. Six kimchi items, including Kimchi mixed with rice, chicken, soybean sprouts, Kimchi cheese rice, stewed beef ribs with kimchi, rice topped with kimchi curry, kimchi cheese meat roast, and kimchi udong were considered appropriate for school meals, whereas kimchi kangchong, kimchi topokki, kimchi stew with surimi, and frozen Pollack kimchi soup were not suitable as menu items. Kimchi topokki was not accepted by students, while kimchi kangchong was not accepted by cooks. Cooks judged the suitability of a menu item by the cooking process and cooking times, whereas students judged an item by its sensory preference. Approximately 63% of students responded that kimchi intake has increased by participating in the development of kimchi dishes.

The purpose of this study is to investigate consumers' knowledge and preference towards functional cosmetics. Through the beauty advisors' surveys, their own selling styles and consumer behaviors recognized by beauty advisors were analyzed. It was intended to help extend and strengthen the functional cosmetic market which has continued to grow rapidly since the approved goods under cosmetic law in 2001. For this study, the data was collected through questionnaires the professional consumer counselors confirmed from Korean women over the age. of twenty old living in the Seoul and Kyoungki areas. After pre-research was implemented on 45 women, 328 samples were analyzed as final samples. In addition,46 samples, which were collected through the questionnaires from beauty advisors were analyzed. Samples were analyzed by frequency, percentage, T-test, ANOVA using the SPSS program. The results of study were as follows: First consumers recognized whether functional cosmetics or not. According to the beauty advisor's surveys, consumers regard the functional cosmetic boundary as being wider than real functional cosmetic boundary according to cosmetic law. So, there is a gap between consumers' opinions and real law. Second, regarding the purchasing channels, the largest channel is the cosmetic store. As far as consumers are concerned the most important factor when buying cosmetics, is the suitability of their own skin types. The second factor is product quality and the third factor is price. Functional cosmetics non-experienced group are more concerned with price compared to experienced group. Related to purchasing products, functional cosmetics experienced group buy set products compared to non-experienced group buy one product. Third, the ultraviolet filter cosmetics portion is the largest in the functional cosmetics market the second largest portion is bleaching cosmetics and the third largest portion is the anti-senility cosmetics. However, Most preferred by consumers is the anti-senility cosmetics. Moreover, preference for ultraviolet filter cosmetics is the least. Finally, the level of satisfaction for functional cosmetics is high and dissatisfaction is low. Consumers feel that beauty advisors are simply pushing high priced products without recognizing the consumers' real needs. In conclusion, to develop the functional cosmetic market continually in the future, it needs to extend various products and advertise them until consumers are more aware.

The experiment was conducted to examine the varietal variation in gelatinization of rice flour and adaptability to rice bread processing, and the interrelation among the relevant properties. IR 44 showed the lowest temperature of gelatinization onset(T$_{o}$ ) and the highest gelatinization enthalphy(ㅿH) measured by differential scanning calorimetry (DSC). The following lower T$_{o}$ was found with the order of Suweon 230＜Pusa-33-30＜T(N) 1, Daeribbyeo 1 and the next higher ㅿ.H was followed by the order of Pusa-33-30＞Suweon 230. IRAT 177 revealed the highest temperature of gelatinization onset and conclusion(T$_{c}$) and the following higher T$_{c}$ was found with the order of Pusa-33-30＞AC 27＞Nonganbyeo. The varietal range of T$_{o}$ and T$_{c}$ was 50.0~72.5$^{\circ}C$ and 70.2~87.4$^{\circ}C$, respectively. The rice materials tested can be classified by scatter diagram on the plane of upper two principal components contracted from DSC thermogram and various characteristics relevant to processing and sensory preference of rice bread by principal component analysis. AC27, Suweonjo and IR 44 among high-amylose rices showed better suitability to rice bread processing. The temperatures of gelatinization peak and conclusion of rice flour checked by DSC were significantly negatively associated with springiness of rice bread. The most properties relevant to processing and sensory preference of rice bread such as hardness, moistness, springiness, cohesiveness, specific loaf volume and distribution or size of air cell revealed the close correlation between each other.other.

This study is to understand the preferences of pilots, flight engineers and crew who work in the same aircraft but are exposed to different working environments and perform different mission operations in order to develop an ergonomic flight jacket. Based on a preliminary investigation, a survey of 107 pilots and 36 flight engineers and crew was conducted. The results are as follows; Pilots can control the temperature inside the cockpit, so they are less exposed to the cold when working, while flight engineers and crew are exposed to the cold more because they have many external tasks. The reason for the problem of the current flight jacket was a difference in ranking between two groups, but the highest ranking was poor dimensional suitability due to the habit of wearing layers of clothing. As a result of preferred design, there were significant differences between groups in the item of overall style. Pilots preferred a bomber jacket style(P:68.2%, E&C:44.4%), on the other hand, flight engineers and crew preferred a field jacket style(P:26.2%, E&C:55.6%)(p<.01). They preferred a stand collar(P:71.0%, E&C:86.1%), a fastener slider for a front fastening(P:62.6%, E&C:61.1%), fastener tape cuffs(P:54.2%, E&C:47.2%), a jacket with a softshell(P:86.9%, E&C:83.3%), fleece as softshell material(P:88.8%, E&C:69.4%), and fastener sliders as a attaching method(P:69.2%, E&C:61.1%). A hem fastening will be selected differently according to the overall style of outshell. Additionally, they preferred more than 5ea pockets(P:51.4%, E&C:44.4%), fastener sliders as pocket's fastenings(P:48.6%, E&C:61.1%), armpit ventilations(P:62.9%, E&C:58.5%). The results of above will be considered to design an ergonomic flight jacket.

The objective of this study was to analyze characteristics of distribution of amphibian species and the affecting ecological factors. For the study, habitat environment factors were determined and applied to a habitat suitability model for the data collected from the Seom River in Hoengseong County and Wonju City, Gangwon Province, Korea between March 2013 to October 2013. The analyzed amphibian species were Rana nigromaculata, Hyla japonica, Rana dybowski, and Rana rugosa Temminck and Schlegel, and a logistic regression model was used with the pseudo-absence data. The result of the model analysis suggests that the major factors for Rana nigromaculata are distance to vegetation and rock and that for Hyla japonica is waterway. Rana dybowski and Rana rugosa Temminck and Schlegel have similar habitat characteristics, but the latter is shown to be dominant due to its wider habitat preference. According to the species richness model, the analyzed amphibian species are shown to have tendency to move between valleys or streams. This study quantitatively analyzed habitat environment characteristics using species distribution model, however, there is a limitation in terms of analysis on food factor and connectivity with other species. Combined with additional density or habitat analysis on birds or fish, this study can lead to more comprehensive analysis on biological environment factors.
