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.

제주도 화산회토 신개간지에 있어서 숙전화를 촉진시키는 한가지 방법으로서 적응력이 강하고 잡초의 재생을 억제하는 능력이 강한 두과작물을 선택하고자 알팔파, 화이트클로버, 채두, 완두, 대두 및 차풀 등의 6개 두과작물을 공시하여 이들의 근류착생 정도를 조사하고 이중 근류착생이 가장 양호하였던 차풀의 잡초와의 경합관계를 조사한 결과는 다음과 같다. 1. 착생된 근류의 무게는 차풀에서 가장 무거웠고 다음은 완두, 대두, 화이트클로버, 채두 및 알팔파의 순이었다. (알팔파는 관찰 불가) 2. 자연초지에 차풀을 파종할 경우 그 건물중은 4년차까지 거의 직선적으로 증가하였으나 띠는 3년차 부터 감소하는 경향이었다. 3. 제주도 지방의 신개간지에서는 지력증진을 위해서 차풀을 재식하는 것이 유리할 것으로 추론되었다.

The mathematical and simulation models to estimate the monthly average daily solar irradiance onthe terminal cladodes of platyopuntia were established. An east-west facing cladode showed maximum irradiance from March to October, while south-north facing one did from November to February from themodel. The orientations and the tilt angles were practically measured on Hallim-eup, Cheju-do. They tended to face east-west, but the overall distribution was deviagted at about 10。 was owing to the southern east wind blowing strongly at that time. The most cladodes inclined to the north or the west rather than erected vertically to the ground. It is thought that the tilt angles were also affected by the southern east wind.

The characteristics of dynamic systems subjected to multiple linear constraints are determined by considering the constrained effects. Although there have been many researches to investigate the dynamic characteristics of constrained systems, most of them depend on numerical analysis like Lagrange multipliers method. In 1992, Udwadia and Kalaba presented an explicit form to describe the motion for constrained discrete systems. Starting from the method, this study determines the dynamic characteristics of the systems to have positive semidefinite mass matrix and the continuous systems. And this study presents a closed form to calculate frequency response matrix for constrained systems subjected to harmonic forces. The proposed methods that do not depend on any numerical schemes take more generalized forms than other research results.

Morphology of 4 dinoflagellates species, Amphisolenia bidentata, A. inflata, A. thrinax and Triposolenia bicornis, which belong to the Dinophysiales, were studied by light and scanning electronmicroscope. The plankton samples for this study were collected from Jeju-Do, South Korea in February, April, September and November 2007. Three Amphisolenia species have large cell size ($125{\sim}890{\mu}m$) then T. bicornis ($45{\sim}50{\mu}m$). Cells of Amphisolenia and Triposolenia with unique morphological features were divided into the head, neck, anterior part of the body (APB), mid-body and posterior process. This is the first record of those four species from Korea.

Today, Korean Disaster Control System has better change the existed it for substantial prevention and the emergency control system. And it requires the new National Wide Disaster Control System through building up the cooperation system with related posts which are scattered over the National Administration and one-way management for disaster affairs by them. Therefore 119 that might have a lot of technical knowhow should be a center of disaster affairs which will be able to take all rescue, relief(first aid), fire fighting, and preventive affairs. Then it could be a service organization of citizen. Consequently, it will strengthen National Disaster Control ability and it could be a National Wide Disaster Organization which is ready for prevention, preparation, confrontation of all kinds of disasters with absolute reliance by the citizen.

The Purpose of this study was to identify factors that influence the self-esteem of the schooler of families in poverty. A descriptive, correlational, and cross-sectional study design was used. The data were collected from February to March, 2001. Convenient sampling was done from 194 subjects living in Jeju Do, but 167 subjects among these were used for the study analysis. Hierarchical Stepwise Regression was used to identify significant factors. The results of this study were as follows: In general, self-esteem status of the schooler in poor families was relatively poor. In stepwise regression analysis, self-esteem status was significantly influenced by emotional home environment, duration of poverty and frequency of parent-child tactics. These variables explained 26.8％ of the variance of schooler's self-esteem. Conclusively, it is recommended that nursing intervention programs for schooler in poor family should be a focus to enhance the economic context as well as family effect.

The purpose of this study is to investigate dining out behavior of college student living in jeju. The data obtained from 533 questionnaires returned by college student. 36.9% of students indicated over-eating, 27.2% did skipping meal, 14.8% did unbalanced diet, and 11.3% did indulging in hot and spicy food as dietary problems of food habits. Many students consumed 5,000-10,000 won/one time. In the breakfast 63.6% of students did not eat out, in the lunch only 10.5%, and in the dinner only 1.7% did not. The students ate out to take a meal in the breakfast, to meet their friends in the lunch, and to meet their friends and to haute social meeting in the supper. They considered intake nutrition and time saving in the breakfast when they ate out. But in the lunch they had various purposes- intake nutrition, time saving, making with relationships, and enjoying taste of foods.

Morphological and anatomical characters of Amphiroa rigida Lamouroux were investigated with field materials and taxonomic accounts are given to the species. The species grows in the subtidal zone of Cheju island, and is characterized by semiendophytic habit in Hydrolithon onkodes. The species is well defined by about 1 cm height, loosely tufted thallus with irregular branches, two-tiered geniculum with equal length, geniculum tier connecting by oblique end walls, and conceptacles buried in cortices of intergeniculum. Korean isolates have etrasporangial, male and female conceptacles. The structure and developmental patterns of conceptacles are very similar to those shown in previous studies.
