고도 정보화 사회로 발전해 감에 따라 사회 전반에서 발생하는 정보들을 컴퓨터에 저장하여 관리하는 정보 관리 시스템들이 많이 개발되고 있다. 특히 컴퓨터 기술의 발달과 통신의 발달은 서로 떨어져 있는 정보 시스템끼리의 정보 교환을 보다 효율적으로 할 수 있게 되어 시스템 통합 환경으로 선도하고 있다. 이에 본 논문에서는 시스템 통합 환경에서 공유 데이타 저장소를 기반으로 하여 지역 데이타베이스를 구축할 수 있는 데이타 모델인 ESR 데이타 모델을 제안하고, 그에 따른 데이타 모델링 방법론을 제안하였다. 또한 공유데이타 저장소를 기반으로 하여 ESR 데이타 모델링을 통한 데이터베이스를 설계할 수 있는 지원도구를 설계하였다.

역전층 현상은 주로 맑은 날 야간 복사냉각에 의해 종종 나타나는 현상으로 사계절 모두 빈번히 존재한다. 하지만 역전층의 발달 정도와 강도 등은 그 날의 일기상태에 의해 크게 좌우되며, 또한 그 지역의 기후 및 지리적인 환경도 중요한 역할을 한다. 본 연구 대상지역인 울산지역은 산업화에 따른 고도성장을 이룬 도시 중 하나로 우리나라 최대공업도시로 잘 알려져 있다. 이와 같은 도시의 야간 역전층 생성 및 발달과정에 있어서 토시 내 인공열의 효과 역시 중요한 요인으로 작용 할 수 있다. (중략)

Analysis of multi-channel seismic reflection and well data serves to detail the structural evolution of the northern Okinawa Trough, southern offshore Korea. The overall structural style of the area is characterized by a series of half grabens and tilted fault blocks bounded by basement-involved listric normal faults. Most half grabens and tilted fault blocks developed in the direction of NNE-SSW, parallel to the axis of the Okinawa Trough. Orientation and distribution of the listric faults also suggest the development of transfer faults in NW-SE direction. The rifting phase of the northern Okinawa Trough have been established on the basis of structural and stratigraphic analyses of depositional sequences and their seismic expressions. Major phase of rifting probably started in the Late Miocene and the most active rifting occurred during the Early Pliocene. The rifting produced a series of half grabens and tilted fault blocks bounded by listric normal faults. It appears that the rifting activity has become weaker since the Late Pliocene, but the Pleistocene sediments faulted by listric faults bounding tilted fault blocks suggest that the rifting activity is probably still in progress.

Objective : The purpose of this study was to investigate the effect of the environmental enrichment therapy (EET) program on the task performance and sensory processing of children with delayed development. Methods : This study was conducted with a single-subject ABA research design for two children with developmental delay findings, and intervention was conducted 7 times a week for 4 weeks. Both children confirmed changes in task performance and sensory processing after intervention. Results : After intervention, task performance improved from an average of 200% to a maximum of 354% compared to the baseline period, and the score in the sensory processing area, which affects tactile processing, emotional response, and activity level, was improved to the normal category. Conclusion : Through this study, it was confirmed that the EET program was effective in performing tasks and sensory processing for children with developmental delays, and its usefulness was confirmed as a program that can be implemented at home.

최근 미국, 영국, 일본 등 선진국들의 정상이 모이는 G7 회담 등에서 논의되고 있는 것들 중 정치적인 문제를 제외하고는 환경문제를 가장 많이 다룬다는 외신보도를 우리는 여러번 접한 바 있다. 산업혁명 후 산업의 끊임없는 발달은 인류에게 생활수준의 향상과 편리성을 도모해 준 반면 환경오염으로 인한 지구파멸이란 위기감을 또한 우리에게 주었다. 1900년 이후 급격한 산업발달에 따른 석탄, 석유등 화석연료의 급증은 대기와 수질오염 등을 야기시켜 마침내는 고농도로 인한 인체피해가 수차례 대두되게 되었으며 이에 따라 1960년 이후 각국에서는 국민 건강 보호를 위하여 나라별로 일정한 기준을 설정하여 대기수질 등 오염물질을 규제하기 시작하였다. 따라서 본 고에서는 여러가지 기준중 대기환경기준 설정에 관한 정확한 의미와 내용을 분석하고 아울러 환경기준 제정시 기초가 된 내용을 상세히 풀이하여 환경기준을 이해하고 이를 지켜 나가는데 도움이 되고자 하였다.

The purpose of this study was to investigate the difference in Korean 4-year-olds' cognitive development depending on variables concerning ecological system variables, predictive influences among these variables, and different predictive patterns between working mothers and non-working mothers. The subjects consisted of 998 4-year-olds, derived from the Korean Child Panel data of 2012. The results were as follows: First, 4-year-olds' cognitive development was different depending on their sex, education level of mother and father, mothers' working status, quality of home environment, and mothers' involvement in children's life in their institution. Second, mothers' involvement in children's life in their institution, children's sex, quality of home environment, and mothers' working status predicted 4-year-olds' cognitive development. Third, there was a different pattern of predictive influence among variables according to the mothers' working status. The mothers' involvement in their children's lives in their institution and children's sex was proved to be important in both, but that was more significant in working mothers, and the quality of home environment predicted cognitive development only in working mothers. These results were discussed in terms of necessity of the Korean national policy to support young children's cognitive development efficiently, especially for working mothers.

Collected and analyzed the coastal processes at the estuary of Nak-Dong river and its near coastal area from the history of field measurements. Introduced a numerical model to predict three dimensional topographical change which are evaluated from the nearshore wave and the wave induced current fields for the objective area, and later it were related to the development of beach and shoals. With the comparison between measured and calculated, we found that the changes on the coastline and sand spit and bar development are induced not only by artificial forces due to the construction of river dike, but also by the strong impact of wave induced current. In future days, it is expected that coastline change and sand bar development at the lee side of Jinwoo-Deung and at the front of Dadae beach.

This study was to know the influence of familial environment and moral development on conduct disorder. Subjects were composed of 47 male and female patients with conduct disorder(patients group), 113 general male and female students(normal group), and 173 juvenile prisoners(JP group). The Korean Form of the Family Environment Scale(FES) was used to assess the family environment of the subjects and the Korean Defining Issues Test(DIT) was used to assess the moral development. Conduct disorder was diagnosed with the DSM-III-R criteria for conduct disorder. The influence of familial environment and moral development on conduct disorder was analyzed with ANOVA and the differences among groups were verified with Scheffe test. There was no difference in the socioeconomic status and the physical abuse by the parents among the three groups. But the rates of divorce or separation of the parents were significantly highest in the JP group and higher in the patients group than in the normal group. Especially the subjects of the JP group experienced the divorce or separation of their parents during the preschool or the elementary school periods. In regard to the family environment, there was no difference among the three groups in the Subscales of Expressiveness, Independence, Intellectual-cultural orientation, Moral-religious emphasis, Organization, and Control. ‘Cohesion Subscale’ was significantly higher in the normal group than in the JP group. ‘Conflict Subscale’ was significantly higher in the JP and patients groups than in the normal group. ‘Achievement orientation Subscale’ was significantly lower in the JP group than in the patients and normal groups. ‘Activerecreational orientation’ was significantly lower in the normal group than in the JP and patients groups. In gegard to the moral developmental stage, the lower moral developmental step was higher in the JP and patients groups than in the normal group. The higher steps were significantly higher in the normal group than in the JP group. There was no significant correlation between the degree of ‘Moral-religious emphasis Subscale’ and the moral development. The clinical implication and limitation of present study were listed and discussed.
