Energy efficiency is vital to improve energy security, environmental and social sustainability, and economic performance. Improved energy efficiency also mitigates climate change by lowering greenhouse gas (GHG) emissions. Buildings are the single largest industrial consumer of energy and are therefore key to understanding and analyzing energy consumption patterns and the opportunities for saving energy at the district level in urban environments. This study focused on two representative boroughs in the major metropolitan area of Seoul, South Korea as a case study: Gandong-gu, a typical residential district, and Jung-gu, a typical commercial district. The sources of the energy supplied to the boroughs were determined and consumption patterns in different industry sectors in Seoul used to identify current patterns of energy consumption. The study analyzed the energy consumption patterns for five different building categories and four different sectors in the building using a bottom-up energy modeling approach. Electricity and gas consumption patterns were recorded for different building categories and monthly ambient temperatures in the two boroughs. Finally, a logarithmic equation was developed to describe the correlation between commercial activity and cooling energy intensity in Jung-gu, the commercial district. Based on these results, recommendations are made regarding the current energy consumption patterns at the district level and government energy policies are suggested to reduce energy consumption and, hence, greenhouse gas emissions, in both commercial and residential buildings.

BACKGROUND: It is essential to prioritize the exact and clear understanding of agricultural nonpoint source pollution (NPS) controls. The realistic policies and systems should also be developed based on this understanding. Therefore, this study aimed to present agricultural Best Management Practices (BMPs) applicable for the fields based on the Delphi survey result. METHODS AND RESULTS: This study deduced the evaluation items to assess each BMP for agricultural NPS control and conducted the surveying using the Delphi method based on agricultural BMP experts. In addition, its on-the-spot application were evaluated. Considering its importance, technical, social and economic proprieties showed that political support was ranked first and followed by cost investment, labor investment, reduction effect and resident participation. The survey findings by agricultural BMP experts showed the good performance of on-the-spot application can be achieved from fertilization by soil testing, residue and green manure application and contour plowing which are applicable within a field. Agricultural BMPs, highly applicable for the fields, were the countermeasures that farmers who are the principal bodies of agricultural NPS control could be participated directly. CONCLUSION: The active participation of farmers is essential for effective control of agricultural NPS. It is necessary to establish various incentive systems.

In Korea, Abortion in the Criminal Law is an illegal act in exception of on which abortion may be carried out through the grounds are very limited and related such a emergency situation of women's physical health, rape, incest and genetic diseases. The Criminal Law regulates the mother's act of abortion and the doctor's surgical performance of abortion. The Mother and the Child Health Law prescribes the medical, ethical, and genetic grounds for the legal permission of abortion. Many people tend to abuse of abortion even though they are fully aware of its illegality. The law lead to be inconsistent with its enforcement. In this paper, I would like to suggest some proposals about the legal analysis of the Abortion Regulations th reform the existing regulation and increase th effectiveness of the regulations. Recently, in a case of the a maternity hospital where a midwife left alone a diabetes pregnancy women who had a baby, and the overweight baby(5.2Kg) died in the uterus due to hypoxic states. Supreme Court of Korea 2007.6.29. 2005do3832) had given a verdict of "not guilty". It looked like there were very fair with current crime law. But, we want this case to be investigated if there weren't any logical contradictions as well as concurrent translation within Constitution Law. Now the Mother and the Child Health Law prescribes the medical, ethical, and genetic grounds for the legal permission of abortion. But this law does not include social and economic grounds.

IT 기술의 성장에 기초한 우리 사회의 각종 뉴미디어의 개발과 도입의 속도, 보급과 서비스의 확산정도 등은 국제적 관심을 주도할 만큼 폭발적이다. 한편 국가 정보화 차원에서 강력한 정책 드라이브를 바탕으로 추진된 정보 인프라의 확대 역시 그에 못지않다. 그러나 문제는 뉴미디어-정보화 정책이 추구하는 산업경제적 가치창출, 사회문화적 가치창출, 지식기반의 확충을 통한 지식사회/지식국가의 토대구축이라는 정책목표가 '사회의 질적 발전(quality development of society)'보다는 '기술과 산업의 양적 성장(quantity growth of industry and technology)'이라는 편향적 형태로 진전되고 있다는 것이다. 이는 개별 정책의 결과이기도 하지만 보다 근본적으로는 개발주의 패러다임(developmentalism)에 기초하고 있는 뉴미디어-정보화 정책의 구조적인 문제에서 비롯된 것이다. 이를 극복하기 위해서 우선적으로 요구되는 것은 '지식 IT 전략(knowledge IT strategy)'에 기초한 뉴미디어-정보화의 질적 발전, 즉 원천기술과 특허의 확보와 그를 통한 기술표준의 구축, 내용과 수준을 갖춘 콘텐츠의 계발, 사회적 지식 네트워크의 구성 등에 부합하는 정책 패러다임으로의 전환이다.

교통체증은 도시지역에서 심각한 경제적, 사회적 비용을 초래하는 원인으로 간주되고 있다. ITS기법은 첨단 센싱, 컴퓨팅, 그리고 통신기술을 이용해 교통체증을 경감시킬 수 있는 훌륭한 수단이다. 본 연구는 차량과 주변 인프라 그리고 차량 간의 무선통신을 통한 중앙제어식 그리고 분산식 첨단통행자정보시스템의 프레임워크를 제안하고 전형적인 $6{\times}6$ 도시형 도로망에서 그 효과를 시뮬레이션 기법을 이용하여 분석하고자 한다. 본 논문의 연구결과로서는 교통류, 무선통신 라디오 레인지 그리고 통신차량의 보급률 등에 따라 제안된 첨단통행자정보시스템은 교통사고로 야기된 정체지역을 우회할 수 있는 최적의 노선을 제공함으로써 운전자의 통행시간을 줄여주는 효과를 보였다. 다양한 연구 환경에서도 중앙제어식 그리고 분산식 첨단통행자정보시스템은 거의 동일한 효과를 보였는바, 분산식 첨단통행자정보시스템은 고가의 건설비와 설치 운영비를 요구하는 중앙제어식 첨단통행자정보시스템을 대신할 수 있는 시스템으로 기대된다.

The purpose of this research is to determine the deterioration characteristics of high-rise and high-density apartment complexes in 1st period new towns in order to regenerate apartments as sustainable residential environments in Korea. For this purpose, the level of deterioration was evaluated by using 'evaluating indicators of the level of deterioration of high-rise and high-density apartments'. The deterioration characteristics were determined inclusively and concretely based on evaluation results. In addition, the deterioration level according to residents' awareness of the deterioration of their apartment was evaluated. This study was conducted by methods of field data collection, staff interview, field measurement, and resident survey according to the measurement of the evaluating indicators. And the re-organized questionnaire based on the evaluating indicators was utilized for a survey of resident's awareness. The results are as follows: In the physical dimensions of apartments, the deterioration characteristics included deteriorated equipment and a decline in structural performance due to the aging of the apartment, a shortage of parking spaces, and the low flexibility of the bearing wall structure, etc. In terms of the social dimensions, the apartments showed an increase in the number of elderly households, a shortage of community facilities, and a lack of the opportunity for community participation etc. In terms of the economic dimensions, the apartments showed limitations in maintenance & repair and a lack of environmentally friendly features.

For most machine tools, it is necessary to remove chips and coolant oil because it they will continue to be created during the manufacture of workpieces. Existing products that are in use are installed and used as they reflect depending on the characteristics of each device separately. This study proposes a method to remove the security chip as well as developing an integrated system capable of reducing coolant damage. The Leverage AutoCAD and CATIA program was used for 2D and 3D design, shapes were identified by utilizing the KeyShot program, and the load and displacement analysis of the development apparatus was performed utilizing the ANSYS program. After the prototype underwent sufficient design review, the mixed oil separation device had a complete sensor control program using the LabVIEW program. The chip design process for transferring experiments and experiments on the mixed oil cooling device were developed for performance tests of the product. The final product resulted in an increase in space utilization during commercialization, reduced installation costs, and caused social effects such as pulmonary flow reduction, which, through the economic costs, reduces pollution, resulting in various benefits to the industry, such as deceased errors in the workplace decreases.

국가 산업발달과 경제발전으로 사회 기반시설 및 각종 편의시설 등에 대한 지하 공간 사용이 급격히 증가되면서 터널과 같은 지하공간에 대한 필요성이 대두되고 있다. 본 연구에서는 지하 공간 발파 시 발생되는 분진저감을 위해 분무 제어 시스템을 개발하였다. 분진저감 효과를 증대시키기 위해 분무 방향을 막장 방향으로 제어할 수 있는 분무 가이더를 고안하였다. AUTODYN 프로그램을 이용한 수치해석을 실시하고 그 결과를 기초실험과 비교하였다. 워터 백 내부 도폭선 위치에 따른 분무 확산효과를 검증하기 위해 중앙장약, 하단장약에 대한 수치해석을 하고 실험을 통해 검증하였다. 최적 조건은 뇌관 외부 기폭과 워터 백 내 도폭선 중앙장약이었으며, 그 결과로 인한 분무 입경은 광산 및 터널에서 발파 후 분진 저감에 적합하였다.
