This research was conducted to develop recommendations for the accreditation system of child care programs in Korea. To assist families in choosing the best child care for their children and to promote excellence in child care settings, an accreditation system of child care programs is necessary. The survey subjects were 262 public, private and corporation child care directors in Seoul, Kyonggi, and Inchon areas. The findings showed that 79.8% of the directors agreed with accreditation systems but they strongly insisted that the necessary time to apply must be well considered with 65.6% of the directors responding that $1{\sim}3\;years$ later was a good time to apply and 37.4% choosing the child care environment as the major area that should be evaluated among the 7 indices of the accreditation system. Most directors were in favor of 7 areas as the indices of accreditation systems while more educated and early childhood education majored directors were more affirmative of the accreditation system.

Many countries of the world is driving forward development of large-scale hub port. They are now pushing ahead with setting up of effective marketing strategies to survive in keen competitions of the 21st century port industry. The port is of ever increasing importance for the bridge connecting sea and road transportation in handling international cargoes. The port, differently from general working places, is a closed area required for security, customs, and quarantine procedures. The loading and unloading is being done differently by ports, cargoes, and ships. To do loading and unloading, a lot of equipment and different types of labor are required, which flow is complicated and safe management is essential. As above mentioned the port is very unique and very deteriorated working place in its working environment. The purpose of this study is to propose ways to reduce and prevent from port accidents. As first step to do this, we have collected 923 accidents happened at Incheon Port during the period of 1994 to 2003. We have thoroughly analyzed characteristics, harmfulness, and risk of the loading/unloading they have done, as well as the accident frequency and relationship between the accidents. As second step to further analyze, We have employed DMAIC technology, an advanced process of 6 sigma presently in spotlight as the best program for management innovation. This analysis results in recognition of important accident characteristics, causes and effects analysis, critical causes of accident, and suggestions to decrease accidents.

The purpose. in this study. is to analyze liquefaction potential of Inchon International Airport at the Area Phase ' I ' for Railway Construction of all, seismic response was analyzed using the computer program, Shake91. Four methods proposed by Seed & Idriss. Eurocode, Iwasaki & Tatsuoka. and Ishihara were used for assessment of liquefaction potential and safety factors calculated form these methods are compared. Based on the results of seismic response analysis, the maximum acceleration at the ground surface is larger than that evaluated site factor effect by using site factor because these areas are composed of very loose sand clay. Especially, in the case of analysis with long period earthquake data. it is appeared that the acceleration of earthquake is amplified more largely. Therefore, accurate seismic response analysis is suggested for the design on the important structures on reclaimed land. The analytical results of liquefaction potential show that the increments of N-value and effective overburden pressure with remediation make safety factors increase. Through comparing the safety factors evaluated from four method, the safety factor calculated by See & Idriss method in the lowest one and it is found that the SPT N-value effect the safety factor very largely. And, Iwasaki & Tatsuoka method is affected by various factors such as average grain size. fine contents, confining pressure. In conclusion. to minimize earthquake Risk by liquefaction, the efficient remediation is essential and seismic response analysis should be carride out.

2차원 천수방정식에 기초한 조류계산 수치모델을 개발하였다. 복잡한 해안선의 입력을 단순화할 수 있는 직각격자를 사용하였으며, 방정식은 효율이 뛰어난 것으로 알려져 있는 인수분해음해법(Implicit Factorization Method)에 의하여 수치적으로 풀었다. 대류항은 상류차분법으로 처리하여 수치소산이 자동적으로 들어가도록 하였으며, 따라서 수치불안정에 의한 발산을 억제할 수 있었다. 모델의 검증을 위하여 선형화된 천수방정식을 풀고 계산결과를 해석해와 비교하였으며 잘 일치하고 있음을 확인하였다. 수치모델의 응용 예로서 인천항부근의 경인운하 개발예정인 수로에서의 조류 계산결과를 보였다.

This study was designed to investigate the relation between stress coping behavior and social adjustments in late childhood. Total 657 teenagers (238 ten-year-olds, 230 twelve-year-olds, and 189 fourteen-year-olds) and their parents living in Inchon area participated in the study. Each child was evaluated whether they cope either (a) defensively or (b) actively in several stressful domains by completing the Stress Coping Hating Scales (Korean). Their social adjustments were measured in areas like peer relationship, family relationship, and conformity with Social Adjustment Scales (Korean). The final examination scores were used to rate children’s Academic Achievements. Finally Korean version of Achenbach’s Child Behavior Check List were completed by parents. As results, girls were found to use more defensive strategies to cope stress, showed more conformity and withdrawn behaviors and achieved higher scores academically than boys. Generally younger children tended to adjust better socially than older children. As children grew older they used more and more defensive strategies to cope with everyday stress. Also older children showed more withdrawn behavior and aggressive behavior than younger children. As anticipated children who used more defensive coping strategies were reported to have more behavior problems, showed poorer social adjustments and academic achievements. Children who used more active coping strategies, on the other hands, were reported to haute less behavior problems, adjusted better socially and had better academia achievements. Finally children who adjusted better socially and had high academic achievements were reported to have less behavior problems.

Secondary vegetation. the holistically integrated system of nature and human being, is the complicated ecosystem that is composed of natural and man-created factors. Understanding the ecological function of secondary vegetation supplies us many important informations for sustainable landscape management and ecological restoration planning. In this research, we tried to examine the shape effect of vegetation patch on early structure of populations of pine and oaks. Moreover. we also tried to clarify the ecological functions of patch edge by exploring the patch effect on germination using patch index. In addition, we present the landscape structure of man -made vegetation of our study area, and setting experimental design of research. Vegetation landscape of study area is typical human disturbed landscape mainly composed of disturbance patches. Vegetation types of graveyard and managed pine forest were controlled by periodically repeated management. However, current seedlings of pine occurred well at both vegetation types. Presence of both saplings were more controlled in managed pine forest (PDM) and graveyard (G) than those of undergrowth (PD) and forest edge (FE) with canopy trees. The number of pine seedlings increased with patch size and patch perimeter. That of oak seedlings was, however, not significantly different. Larger graveyards provided higher light availability for germination of pine seedlings. We think, however, most seedlings of both species in the large sized graveyards without shade will die more easily than that of small sized ones before rainy summer. Relationships between patch shape and germination of two woody species cannot be exactly explained enough yet in these results. More informations on spatial interaction of the total species with differently sized patches are necessary to solve the concept of patch effect on species colonization.

The purpose of this study was to define the content of physiological knowledge needed for clinical nursing practices. Subjects of physiology were classified into 15 areas, and each areas was further classified into subareas, resulting in a total of 194 subareas. The degree of importance of each subarea was measured with a 4-point scale. The subjects of this study were 179 nurses of two university hospitals located in Seoul and Inchon. The results were as follows : 1. The areas of physiology necessary for clinical nursing practice as a basic knowledge in the order of importance were : blood, respiratory system and renal physiology, function of the immune system, body fluid and cardiovascular system, body temperature, endocrine physiology and gastrointestinal physiology However, the degree of importance for reproductive physiology, neuro-physiology, energy and metabolism, cell and cell membrane physiology, muscular physiology and special sense was relatively low. 2. The most important content of physiology for all clinical areas in nursing was blood physiology. However, the degree of importance for each physiology area was different depending on clinical areas. 3. Subareas of physiology as a basic knowledge for clinical practice and education in nursing were blood transfusion, blood type, function of red blood cell, white blood cell and platelet, characteristics and function of hemoglobin, composition and function of plasma protein, and mechanism of blood coagulation and anticoagulation. In conclusion, areas of physiology necessary for clinical nursing practice were blood, respiratory system and renal physiology, function of immune, body fluid and cardiovascular system, body temperature, endocrine physiology and gastrointestinal physiology.
