  • This study aims to redefine people's attitudes about well-being trend LOHAS(Lifestyles Of Health And Sustainability) by a systematic research on diners' perspectives about LOHAS and menu-selecting behavior since well-being trend has been a main interest of the media and the food service industry. Also, this study has focused on understanding customers' menu-selecting behavior through a customer interest survey and on customers' interests and verifying factors for healthy food inclination and satisfaction level to give basic information and marketing suggestions for healthful menu. SPSS 12.0 was used for the data analysis, and $x^$-test was carried to make clear the different perspectives about well-being trend LOHAS according to the general characteristics of those polled. Factor analysis was done to menu-selecting behavior. Differences between sampling menu-selecting factors and general characteristics(t-test & ANOVA) were inspected and multiple regression analysis between health inclination and satisfaction level was also conducted. According to the survey, customers' well-being menu selecting behavior showed highly in married women, relatively older people, those with higher general income and higher education. Regression analysis showed that menu-selecting behavior influenced customers' inclination toward health and satisfaction level. Therefore, the food service industry should target those groups and improve its promotional communication strategy with proper menu development and an improved concept.

  • Objectives: Employee exposure record refers to a record containing information about environmental (workplace) monitoring or measuring of a toxic substance or harmful physical agent. The aims of this study were to examine problems related to exposure records and provide some amendments to the Korean Industrial Safety & Health Act for the effective management of chemical substances under the law. Methods: This study performed a literature search and review on legal provisions related to exposure records of a number of different countries, including Korea, the USA, Japan, EU, Germany, and the UK. They were compared and investigated and the amendment of articles was suggested. Results: The results of this study were provided as suggested amendments to the related act. There were a variety of ways of improvement, including a 30-year retention period and the introduction of new access methods, contents, transfer, and maintenance methods. All exposure data elements have to be standardized, including reference to a similar exposure group (SEG), sampling strategy, and circumstances of exposure (e.g., date, shift length, use of personal protective equipment, etc.). The SEGs are described by process, job, task, and environmental agent. Conclusions: This study is expected to provide for the amendment of the related act in order to ensure effective management of exposure records and is helpful for solving the cause and result of occupational disease by keeping exposure records according to the Industrial Safety & Health Act.

  • Postpartum depression is one of the most serious problems in maternal health because it affects not only the mother but also her family. Postpartum depression disturbs the maternal-infant interaction and attachment. However, most postpartum depression patients ignore this problem and do not seek treatment. Many clinicians and researchers realiza there is a need to develop a postpartum depression scale. Thus, this study has been designed to development of a postpartum depression scale. Data were collected through a survey over a period of three months. Subjects who participated in the study were 167 Korean mothers in their postpartum period. The author used a convenience sampling method. The analysis of the data was done with SPSS PC/sup +/ for descriptive statistics, item analysis and factor analysis. Initially 62 items were generated from the interview data of eight postpartum depression patients and from a literature review. This preliminary scale was analyzed for reliability and validity. The results of this analysis are as follows. 1. Initially 62 items were analyzed through the Index of Content Validity(CVI) and 48 items were selected. 2. Seven factors were extracted through the principal component analysis, and these contributed 61% of the variance in the total score. Finally 46 items in the scale loaded .41∼ .84 on one of seven factors. 3. Each factor was labeled. Factor 1 was labeled 'emotional phenomena-emotional upset' and included 13 items, factor 2 was labeled' cognitive phenomena-self concept disturbance' and included seven items, factor 3 was labeled 'relationship to baby-negative feeling' and included six items, factor 4 was labeled 'relationship to baby- overload' and included eight items, factor 5 was labeled 'negative maternal identity' and included five items, factor 6 was labeled 'biophysiological phenomena-disturbance of physical functioning' and included four items, and factor 7 was labeled' interpersonal relationship phenomena-blamed others' and included three items. 4. Cronbach Coefficient Alpha for internal consistency was .95 for the total 46 items. Finally, the author suggests that this scale could be adequately applied in assessing the postpartum depression of mothers during the postpartum period. The results of this study can contribute to designing an appropriate postpartum depression prevention strategy.

  • This study has been done by giving the guide when development of menu or doing marketing strategy in Hotel Restaurant. All products and service has a regular course from induction in market to disappear, so it shall be come out Products Life Cycle theory. In eating business, under the tendency and existing cycle to change menu by taste of customers, liking variation, change of periodic status (environment), MLC(Menu Life Cycle) shall be advised by application PLC(Products Life Cycle) in the process of induction of some menu first and spreading the same business field and then deletion (disappearance) from menu because of no popular. In Emergence Stage, it shall be tried to inform new menu through Cooking Contest, presentation of new menu, free sampling party and others. In Growth Stage, it shall be changed package menu or set menu. In Maturity Stage, it shall be provided complimentary ticket, gift coupon or discount for the customers with some degree of selling record in order to increase using frequency and selling amount after insure new customers. In Decline Stage, it shall be groped for entry underdeveloped country or less advance nation, but there is no possibility to devote in enterprise, it shall be planned substitute menu development in order to withdraw. By inducting MLC concept, it shall be provided the available informations such as“how could some menu be circulate in some restaurant”“Accordingly do strengthen promotion activities or go to low developed area or overseas, or delete it from menuitems and so on”. In the time of decline some menu, it is judged to the time of plan(preparation) of new menu development. In the broad view, when consideration of the concept of menu life cycle, it shall be possible to know which menu is decayed and which menu is developed newly or grown-up, so it shall be provided the important information to estimate the tendency of changing menu and set-up a menu development plan.

  • Purpose: This study was carried out in order to examine organizational commitment in dental technicians and turnover intention level according to it, and to analyze its effects. Methods: A self-reported questionnaire survey was carried out by having convenience sampling as 200 dental technicians. An analysis of the collected data was computationally processed by using SPSS Win 19.0 program. An analytical technique was made by using statistical techniques such as frequency & percentage, t-test, One-way ANOVA analysis. The following are the analytical results of the collected materials. Results: In consequence of analyzing organizational commitment level in research subjects, there was a significant difference in the items for age, task field, job position in charge, career in dental laboratory technology, and monthly income(p<.05). The average of the item for organizational commitment level stood at 3.29, thereby having been indicated to be high. As a result of analyzing turnover intention level in research subjects, there was a significant difference in the items for task field, job position in charge, career in dental laboratory technology, and monthly income(p<.05). The average of the item for turnover intention reached 3.04, thereby having appeared to be relatively high. As for a correlation between organizational commitment and turnover intention, all variables were shown to have inverse correlation at a significant level. In consequence of conducting regression analysis in order to analyze the influence of organizational commitment upon turnover intention, a factor of having the most impact on turnover intention appeared to be normative commitment. The test value of the model was statistically significant. The explanation power about this was indicated to be 26.9%. Conclusion : In the above findings, the dental technicians are considered to need to be immersed in work with a sense of mission in performing job in charge, to strive to possibly have an opportunity of achievement and self-growth, and to perform a research and development in a manpower management strategy such as turnover prevention.

  • There are differences in preference according to the brand signal explicitness when selecting fashion luxury brand, and the purpose of this study is to verify the moderating effects of self-construal and implicit theory in relation to those preferences. This study divided the experiment design into two $2{\times}2$ mixed design studies: Study 1 and Study 2. The study 1 was composed of the following factors: brand signal explicitness(subtle vs. explicit signal) and self-construal(independent vs. interdependent self-construal). Study 2 was composed of the following factors: brand signal explicitness( subtle vs. explicit signal) and Implicit theory(entity vs. incremental theorist). Convenience sampling was conducted to find the subjects of study 1 and study 2. Study 1 analyzed data from 172 women in Seoul, Gyeonggi-do and Busan who prefer luxury brand, and study 2 used data from 138 women. The results of this study are as follows. 1) Independent self-construal primed group was shown to prefer subtle signal product to explicit signal product, whereas interdependent self-construal priming group preferred explicit signal product to subtle signal product. 2) The entity theorist to prefer explicit signal product to subtle signal product. On the other hand, the incremental theorist did not show significant difference in the preference between subtle and explicit signal products. Therefore, the results of the present study shown the importance of understanding consumers through the difference depending on consumer inclination and psychology, recommending preferred luxury brand according to the inclination of the target customers, and establishing segmented marketing strategy to captivate consumers with these various characteristics.

  • The purpose of this study was to identify the significant predictors of drinking problem among college students attending health and welfare department. A total of 538 college students attending health and welfare department were selected through convenient sampling. Data were collected using self-reporting questionnaires, which were constructed to include depression, anxiety, abstinence self-efficacy, and drinking behavior. SPSS 18.0 was used for data analysis and descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson Correlation coefficients, and multiple regression were done. Drinking problem was positively correlated to the depression and anger while negatively correlated to the abstinence self-efficacy. The significant predictors of drinking behavior were sex, grade, anxiety, and abstinence self-efficacy. The result of this study suggest that drinking problem prevention program should consider improving self management skills by effective management of negative emotions along with enhancing self-efficacy as a cognitive strategy.

  • Sesame (Sesamum indicum L.) is one of the most important oilseed crops with high oil contents and rich nutrient value. The development of a core collection could facilitate easier access to sesame genetic resources for their use in crop improvement programs and simplify the genebank management. The present study was initiated to the development and evaluation of a core collection of sesame based on 5 qualitative and 10 quantitative trait descriptors on 2,751 sesame accessions. The accessions were different countries of origin. About 10.1 percent of accessions were selected by using the power core program to constitute a core collection consisting of 278 accessions. Mean comparisons using t-test, Nei's diversity index of 10 morphological descriptors and correlation coefficients among traits indicated that the existing genetic variation for these traits in the entire collection has been preserved in the core collection. The results from this study will provide effective information for future germplasm conservation and improvement programs in sesame.

  • The purpose of this study was to assess biological river water quality by using epilithic diatoms at 40 selected sites in Geum, Youngsan, and Seomjin River systems. The sampling and analyses were performed during three seasons including January, April and June in 2005. Various water quality parameters also were analyzed. We attempted to classify the water quality condition by epilithic diatom indices (DAIpo and TDI) with the results of corresponding analyses of various chemical water quality parameters. A five class system was delivered to describe the water quality condition ranged from "very good" to "very poor." We also proposed a way of classifying water quality condition by combining two diatom indices of DAIpo and TDI. Our results showed that biomass of epilithic diatoms varied not only seasonally but spatially; it was not likely that winter diatoms represent average water quality condition, due to high concentration of nutrients. Water quality status assessed by diatom indices was generally worse than that assessed by BOD, indicating that BOD standard likely underestimates the biological condition of the water body. Importantly, nutrient-based diatom index (TDI) generally overestimated organic matter-based index (DAIpo) at most study sites, indicating that diatoms in studied rivers were likely more affected by nutrients than organic matter. Thus, management strategy to improve river water quality in Korea is suggested to emphasize more on the nutrients than organic matters.

  • The objectives of soil investigation in risk assessment of contaminated sites are to characterize the level and area of contamination, and provide the important physical and chemical properties of contaminated sites for later exposure assessment. This study suggests two soil investigation strategies to be considered in the soil risk assessment in Korea. First, soil investigation for characterizing soil properties is additionally required to the current investigation method that has focused on chemical analysis. Second, application of statistical concepts to soil investigation plan and soil data analysis are required for confidential decison-making on contamination and determining the exposure soil concentration. This study provides a practical soil investigation strategy to involve the current Korean soil analysis guidance with the minimum sample number required for satisfying statistical limits.
