Organizations of airport continue to invest heavily in the acquisition of self-esteem. Because, it is that self-esteem will become more productive. In this article, We verify to influence in the operation performance by the air navigation system and moderated effect of self-esteem. A survey of Incheon International Airport and Gimpo International Airport was conducted to better understand the factors that affect air navigation system to explain operation performance of airport perspective on air navigation system operator. The findings indicate that the positively moderated self-esteem affects operation performance of airports. We also confirmed that air navigation policy, maintenance, and promotion activities of air navigation system factors are affecting the operation performance of airports. The results of this study suggest that self-esteem could be the basis for a strong measurement tool to evaluate whether self-esteem in a given organization of airport are meeting enhancement of operation performance.

The present investigation was undertaken to study the effects of non-genetic factors and association among replacement and lifetime production traits. The data on 542 Holstein Friesian cows maintained during 1975-98 at State Cattle Breeding Project, Sector III, Hisar, were utilized. The average sex-ratio, abnormal births, mortality, culling and replacement rates on total calf born and total female calf born basis were 51.62, 8.50, 17.52, 31.05, 22.78 and 51.41 per cent, respectively. The study revealed that a minimum of 4 to 5 progenies are required per cow over its lifetime to replace itself. It indicated that each cow should produce a minimum of 2 female calves during its life so as to replace herself before being lost. The least-squares means for productive herd life, longevity and lifetime production were $1439.32{\pm}87.64$ and $2419.18{\pm}8.25$ days and $11317.95{\pm}913.15kg$, respectively. The heritability estimates for all replacement traits were very low indicating that sire selection may bring no desirable change in these traits. Heritability estimates were $0.178{\pm}0.157$, $0.288{\pm}0.184$ and $0.096{\pm}0.195$ for corresponding lifetime production traits. Breeding values and ranking of sires were generated for replacement and lifetime production traits to estimate the rank correlations between these traits. Moderate desirable rank correlations were obtained between replacement rate and lifetime production traits indicating that sires proven on the basis of milk production are also expected to have better replacement rate.

We analyzed the questionnaire survey for the current maintenance of Incheon port's loading and unloading equipments and the possibility of TPM(Total Productive Maintenance) application. And also, We certificated Structural Equation Model with computer packages. Results of the survey indicated that the current maintenance of Incheon port's loading and unloading equipments was not good. We recognized the relationship of contextual factors about the productivity of the loading and unloading equipments The productivity of the loading and unloading equipment positively depends on maintenance management of equipments, but the organization and personnel management does not have a influence on the productivity of the loading and unloading equipment. So we suggest TPM as the future maintenance methodology of equipments. Using TPM to the loading and unloading equipments, we will try to improve the methodology of the organization and personnel management.

The purpose of this study was to investigate the factors influencing social adaptation of chronic mental illness. The subjects of this study were 190 patients, over the age of 20 with chronic mental illness diagnosed by a physician, and living in Seoul, Korea during May, 2000 to December 2000. The instruments for this study were the social adaptation scale by Wallace (1979), the self-esteem scale by Rogenberg (1965), social support scale by ParkJiWon (1985), coping behavior scale by Shirley Zeitlin (1978), self efficacy scale by Sherer et. al (1982), and Rand mental health inventory(1979). The data were analyzed using descriptive statistics, pearson correlation coefficients, and stepwise multiple regression. The results of this study are as follows: 1. The level of social adaptation showed moderate (M=3.43). 2. The social adaptation showed significant positive correlation with self-esteem (r=0.39, p=0.00), self-efficacy (r=0.31, p=0.00), social support (r=0.47, p=0.00), self-productive coping (r=0.14, p=0.05), self-flexible coping (r=0.22, p=0.00), environment-active coping (r=0.21, p=0.00), and environment-flexible coping (r=0.14, p=0.04). The social adaptation showed significant negative correlation with anxiety (r=-0.16, p=0.02), and emotional problems (r=-0.18, p=-0.00). 3. The stepwise multiple regression analysis revealed that the most powerful predictor of social adaptation was social support (21%). A combination of social support, depression, behavioral controllability, self-efficacy, and environmental coping behavior accounted for 39% of the variance in social adaptation in chronic mental illness. From the results of this study, it is suggested to develop and apply a social adaptation training program for chronic mental illness.

Although Korea is short of capital technology, and natural resources, she has achieved an outstanding progress by the export-drive policies by Korean government and the creative endeavor of Korean firms. As a result of that, Korean economy and enterprises are in the same file of newly industrialized countries and Korea is ready for an economic take-off as a developed country. But in the early 1980s, each country strengthens protective trade theory and resources nationalism, and this has a great influence on the field of international trade environment. In spite of that, to continue the same high development as that of the past. Korea must try to secure and find export markets, solve trade barriers, make sure of the long-term security of resources, develop technology, and strengthen economic cooperations. To satisfy these desires by 2000s, we must try to make Korean enterprises have the global competitive power and them grow strongly among world wide firm through capital and technology accumulated during the passed years, and to do so, there must be a foreign production and marketing management, too, this can be achieved only through foreign overseas direct investment. This investment has various forms, to say, verifical integrated, horizontal integrated. conglomerate integrated forms, and the amount of investment in each country from 18 century to today reaches 500 billion dollars. This investment is done by strategic, behavioral economic, and financial motives. So I am going to approach the fields of like these; in spite of the differences among political, economical, caltural, and social systems, and many risk compared with domestic enterprises, why do Korean firms witsh to transfer the productive facilities to overseas countries and run them there? What is the comparative advantage of foreign direct investment compared with domestic investment ?. why is the factor of comparative advantage transferred through foreign direct investment?, what is the motive of foreign overseas direct investment?, and last the ownership-specific factors and the theory of internalization, and the location specific factors were analysed chiefly. But in consideration of the given condition in Korea, Korean overseas direct investment must be propelled rationally on the basis of the above mentioned theory.

The purpose of this research is to investigate and analyze food allergy labelling for the arrangement of improvement plans. Survey was done as a quantitative research targeting food industry employees with 399 random workers in Seoul and Gyonggi area. The data was analyzed using SPSS windows (ver. 12.0) for frequency analysis, t-test and factor analysis. The importance and performance of the food allergen labelling were divided by 15 items. Only 43.1% of the workers understood the operation allergic food labels. The first improvement on allergic food labels was "using boldface for food allergen labes". The importance of all of these factors was significantly higher than performance. The selection attributes with relatively low the performance but high importance(2 quadrant) were "consumer education for allergic food labels" and "training of professional counselors on food allergy". Therefore, the factors to be improved through the IPA were consumer education and training of professional counselors. With this research and extended efforts for revision of laws, reliability of food industry and accuracy of food labelling would improve, thereby boosting the productive commercial activities in labelling code.

In this study, the implications for landscape architecture in the restoration Project of Cheonggyecheon will be shown through the analysis of factors for landscape architect scheme modification. The method of study consists of theoretical study, analysis of the plan and design of landscape architecture of the restoration project of Cheonggyecheon, and deduction of implications thereof. The controversial feints included the many difficulties in realizing the productive design of landscape architecture due to the selective collecting of public opinion and the problems of settling the complications, the design limit of the turnkey and MA systems, the lack of hydraulic knowledge and technology and the shortage of vegetation monitoring data and experimental materials. The alternative proposals are as follows: 1) there should be agreement between the government organization and the civil group, 2) in the turnkey bidding for the river restoration projects, the river restoration design based on the volume divided into some parts should be reconsidered in order to maintain consistency in the total design, 3) in order to maintain consistency in the planning policies, MA designs should also be introduced and applied from the first stage of the project through its completion, and 4) data such as the safe water level in case of flooding for the facilities and the vegetation and data in connection with the ecological restoration of river should be accumulated. If these controversies are not settled effectively, the river restoration project will be delayed due to complications with the citizens and wasted time and effort will result from the frequent design changes. In addition, landscape architecture in this kind of restoration project is bound to decrease in the future due to frequent changes in the hydraulic-centered design.

Objectives： The aim of the present study was to determine the prevalence depressive symptoms, and the correlates of depressive symptoms, and to propose countermeasures for individual depression risk factors among college students. Methods： One university and three colleges in Jeju-do were selected as the study population and a total of 1000 students were selected by multiphasic cluster sampling to represent each department and year within each college. Of the 945 total respondents, 421 were men and 524 were women. The Beck Depression Inventory was used to evaluate depression and the BDI STEN score was used to assess depressive symptoms. Multiple logistic regression analysis was performed for comparisons. Results： 1. The prevalence of depressive symptoms among men was 14.4%, while among women the level rose to 26.8%. 2. Those with poor life satisfaction scores were significantly more likely to have depressive symptoms than those with good life satisfaction (odds ratio (OR) ＝ 2.62； (95% confidence interval (95%CI), 1.483-4.629). 3. Students over 23 years old were significantly more likely to have low levels of depressive symptoms than those under 18 (OR ＝ 0.439； 95%CI, 0.247-0.779). 4. Groups with poor body image satisfaction had higher levels of depressive symptoms when compared to respondents who had good body image (OR = 2.847; 95%CI, 1.341-6.045). 5. Students with poor perceived health status were significantly more likely to have high levels of depressive symptoms than those with good perceived health status (OR ＝ 2.029； 95%CI, 1.157-3.557). Conclusion： Universities and colleges should provide education programs, such as health education that facilitates the development of a healthy body image. In addition, they should focus on various scholarships that could improve satisfaction with student life, especially for alienated students. Furthermore, colleges should help direct students towards engagement in more productive work, and lead social policies away from the dominance of appearance.
