The purpose of this study was to investigate the longitudinal relationship between Korean youth's social withdrawal, depression and community sense mediated by achievement values. For this purpose, we analyzed three years of the longitudinal panel data (2011-2013) of the Korean Children and Youth Panel Survey (KCYPS). Data were collected from 2,351 first year middle school students using the latent growth model using SPSS 18.0 and AMOS 22.0. The main analysis results were as follows. First, social withdrawal and depression decreased and community sense increased as time passed. These results supported the linear change model. Second, the initial status of social withdrawal and depression had effects on the initial status and change rates of community sense. Achievement values, the partial mediator, had a positive influence on initial community sense but had a negative influence on change rates of community sense. We discussed how to improve Korean youth's community sense based on these results.

조피볼락 Sebastes schlegeli 자어와 점농어 Lateolabrax sp. 자어를 대상으로 기아시 성장과 간세포 핵 크기 변화를 조사하였다. 전장과 습중량 성장에 있어 조피볼락과 점농어의 간세포 핵 크기는 첫 먹이 섭취 자어의 영양상태와 연관성을 보였다. 본 연구의 조피볼락과 점농어 자어에서의 기아시 간세포 핵 크기 조사 결과는 조피볼락과 점농어에서 초기 영양상태 판명의 지표가 될 수 있으며 초기 먹이 공급 공정시 내생적 영양상태에서 외생적 영양상태로의 효율적 전환을 가능케 할 것으로 사료된다.

Advances in neonatal care system and research have resulted in an increased survival rate among low birth weight infants in the industrialized countries. Recent Korean neonatal mortality and morbidity statistics, and current status of Korean neonatal intensive care facilities were reviewed here for the sake of future improvement and research. Morbidity statistics revealed that perinatal diseases accounted for 80％ of the death of premature infants implying the possibility of its reduction by the vigorous prenatal care service in future.On the basis of extensive studies of nutritional support and growth rate of premature infants, commercial formulas for premature infants have been developed and various aspects of feeding techniques are standardized. However, problem of growth deficit of premature infants remains unsolved as medical problem. NICU specialists are challenged with the tasks of prenatal education or provision of care that minimizes the neurodevelopmental problems seen in preterm infants, various short-term outcome researches have been reported and those are reviewed here to promote research interest in the field of neonatal nursing. Systemic long-term outcome studies are also awaited in Korea for the formulation of welfare policy in future. Nursing science has to embrace all these interdisciplinary studies as their own research field in collaboration with neonatologist, nutritionist, rehabilitation therapist, social workers and teachers.

This study aims to estimate the economic effect of Korea's transition to a developed country in WTO negotiations. If Korea develops into an advanced country, it must give up many advantages in the agricultural sector. In particular, limiting the scope of sensitive items, giving up the selection of special items, and drastic tariff reductions are expected to have greater negative effects on the agricultural sector. According to research results, Korea's GDP rose slightly from 0.2 to 0.8 percent following the DDA settlement. Especially when China is classified as an advanced country along with Korea, Korea's GDP appears to be growing even more. On the other hand, damage is expected in most areas of agriculture. The trade deficit in the agriculture sector is expected to widen as output in the agricultural sector decreases, and import growth exceeds export growth. In the non-agricultural sector, there are no significant differences in the change in WTO status. However, if China is grouped together as an advanced country, the export growth rate of the Korean manufacturing industry appears greater.

The origin and present status of research and commercial production of Korean Ogol chicken are reviewed. The Yeonsan Ogol chicken was designated as a National Monument (No.265) at April 1, 1980. After that, researches have been done on the various aspects of Ogol chicken, i.e., external characteristics, growth and reproductive performance, chemical composition of egg and meat, and carcass characteristics. In addition, several genetic parameters of Ogol chicken have been estimated.
