The Pusan Container Terminal faces a rapid increase in berthing time of container ships as well as in waiting time of external trucks, which is due to an absolute lack of yard space. This research is focused on the development of a decision support system for the planning of the container terminal yard assignment so that the yard space would be utilized most effectively. Efforts should be given to the reasonable assignment of the yard storage and the dynamic adaptation to the ever changing environment. The software introduced here is based o the know-how of the field exports and its framework takes the approach of the hierarchical decision making.

It is recognized that reinforcement corrosion is the main distress behind the present concern regarding concrete durability. In this study, to confirm corrosion of reinforced concrete due to permeability of carbonation and chloride ion affected by thickness of cover, kinds of surface coating, measured electric potential, ratio of corrosion area, weight reduction, corrosion velocity of steel bar under environment of complex deterioration. The results showed that an increase in age also decreases Carbonation velocity coefficients and increases Chloride ion diffusion coefficients. As well, an increase in age also increases corrosion of reinforcement due to permeability of carbonation and chloride ion. Corrosion of reinforcement by thickness of cover is superior to 10mm thick than 20mm thick. It showed that an increase in thickness of cover prevent steel bar from deteriorating due to permeability of carbonation and chloride ion. The results of this study showed that corrosion velocity was affected by thickness of cover, kinds of surface coating. data on the development of corrosion velocity made with none, organic B, organic A, inorganic B. and inorganic A is shown.

A partial and preliminary report of the reproductive performance of swine in the south eastern part of Korea (Youngnam province) during 1983 was given. For the 871 farrowings recorded, the mean litter size at birth was 8.9 and 0.61 piglet per litter was stillborn. Of the total number of piglets born alived, some 15.4 percent never reached the age of weaning, the vast majority succumbing within 3 days of birth. The major factor of piglet death from birth to weaning were diarrhoea (34.6%), crushing(17.4), weak pigs (15.8%), starvation(11.8%) and pneumonia (6.7%).

In this study we investigated the effects of supine ergometer exercise on physiological and psychological relaxation. Seven healthy young men(aged 24.4±2.00years) volunteered for the experiment. The experiment consisted of the following three successive segments" A pre-exercise period of 10 min, during which the subjects rested in a supine posture with their eyes closed for the final 5 min; an supine ergometer exercise period of approximately 10 min, during which the subjects performed intensity of 50%HRmax exercises; A post-exercise recovery of 5 min, and a recovery of 10 min, which was similar to the pre-exercise rest period. The electroencephalo-graphic(EEG) activity of the central cortex of the brain were measured pre-exercise, post-exercise 5 min, and recovery phase 10min. Fast Fourier Transformation of the EEG was used to obtain power spectrum areas in the delta(0.5~4 Hz), theta(4~8 Hz), alpha(8~13 Hz) and beta(13~30 Hz) frequencies. We compared the relative power values(power %) of the electroencephalogram alpha bands(8~13 Hz) and korean edition of the profile of mood states(K-POMS) before and after the supine ergometer exercise. We also estimated the percentage of maximal heart rate(%HRmax) throughout the experiment to ascertain the intensity of the supine bicycle ergometer exercise. The results of %HRmax indicated that the intensity of supine exercises practised in the experiments ranged from low to moderate. The power % of EEG alpha bands had increased significantly after the supine ergometer exercise compared with the pre-exercise rest(p<0.05). From the POMS results, we observed that positive mood(vigour) increased and negative mood(tension, depression, and total mood)decreased significantly after the supine ergometer exercise(p<0.05). This study found that the subjects showed increased physiological and psychological indices of relaxation after supine bicycle ergometer exercise.

연구목적: 본 연구는 공동의존성에 영향을 미치는 아동기 가정내 스트레스 요인과 공동의존성과 다른 병리와의 연관성을 규명하고자 하였다. 더불어 특정한 질환에서의 공동의존성의 평가가 가지는 의의를 탐색해 보고자 하였다. 방 법: 연구 대상은 정상 일반인 남성집단 88명과 알코올리즘 남성 집단 76명으로 구성되어 있다. 평가도구는 본 저자가 직접 작성한 '아동기 가정내 스트레스 요인 측정용 설문'과 공동의존 척도(RPS), 간이증상 진단검사(SCL-90-R)를 사용하였다. 통계적 분석은 Mann-Whitmey test, Kruskall- Wallis test, Multiple linear regression analysis, Spearman correlation analysis를 이용하였다. 결 과: 1) 정상 일반인 군과 알코올리즘 군의 공동의존성 평균값은 각각 49.12점(표준편차=15.41)과 88.31점(표준편차=17.48)이었다. 2) 정상 일반인 군에서는 '아동기 부모 사별'(p<0.01) '부모의 알코올리즘'(p<0.01) '부모의 상습적 구타'(p<0.01)의 3가지 요인에서, 알코올리즘 군에서는 '어린시절 부모 사별'(p<0.01) '부모의 알코올리즘'(p<0.01) '부모의 상습적 구타'(p<0.01) '부도의 도박'(p<0.01) '사회 병질자 부모의 존재'(p<0.05)의 5가지 요인에서 스트레스 유무에 따라 공동의존성에 유의한 차이를 보였다. 3) 두 집단 동시에 SCR-90-R의 8개 소척도 중 '대인관계 예민성'이 공동의존성과 가장 높은 연관성(rs>0.06, p<0.01)을 보였다. 이외에도 '우울증' '불안증'등이 두 집단 모두에서 통계적으로 유의한 연관성을 보였다. 결 론: 본 연구는 부모의 알코올리즘뿐만 아니라 여러 가정 내 스트레스 요인이 공동의존성의 발생에 영향을 미칠 수 있음과 공동의존성이 높은 집단이 다른 정신과 질환을 동반할 가능성이 높음을 증명한다고 할 수 있다. Objectives : The aim of this study was to examine the relationships of codependency with family stressors in childhood and psychopathology. Methods : Subjects were a group of 88 normal adult males and a group of 76 alcoholic males. The degree of codependency was assessed with the Korean version of Recovery Potential Survey(RPS). All subjects filled out questionnaires regarding demographic information and family stressors. The psychopathology was measured by self-administred questionnaires using Symptom Check List-90-Revision(SCL-90-R). Results : 1) There were no significant differences in codependency levels by sociodemographic characteristics in two groups, but obvious difference in mean of codependency scores(normal group : 49.12±15.41, alcoholism group : 88.31±17.48). 2) There were significant differences in codependency levels between the presence and absence of parental physical abuse, parental death, and parental alcoholism(p<0.01) in both groups. 3) Among family stressors, parental physical abuse had the largest contribution to codependency level in multiple linear regression. 4) There were significant correlations between the codependency levels and the scores of SCL-90-R's subscales of interpersonal sensitivity, depression, and anxiety in both groups. Conclusion : The codependency levels were related to some family stressors such as parental physical abuse, parental death, and parental alcoholism and the high-level codependency was correlated with higher level of psychopathology in both normal and alcoholism group. These results suggested that various family stressors, as well as parental alcoholism may be predictors of codependency, and codependency also may be a predictor of other psychiatric disorders.
