서울시청 엘리베이터에 자가발전소가 갖춰졌다. 생산된 전기는 시청 조명을 밝히는데 사용된다. 서울시는 고유가와 지구온난화에 대비하고 화석연료 사용 줄이기에 실천적으로 나서기 위해 행정기관 최초로 엘리베이터 운행 중 발생하는 전기를 회수하는 자가발전설비를 설치했다. 엘리베이터 자가발전원리는 엘리베이터가 상승하거나, 하강할 때 권상기 모터의 회전력이 발전기로 작동하면서 실시간으로 전기를 생산하여 건물의 조명, 동력으로 되돌려주는 시스템이다.

중국국내중재제도의 형성과 발전은 20세기 80년대 초반으로부터 시작되었습니다. 1983년 국무원에서 <중화인민공화국 경제계약중재조례>를 반포한 뒤, 국가공상행정관리국에서는 <경제계약중재위원회판안규칙>을 제정하였으며, 이에 따라서 지방의 공상행정기관은 중재위원회을 설립하였고 경제계약분쟁을 해결하기 시작하였습니다. (중략)

The purpose of this study is to identify increasing needs for training students as managers in social service agencies and to suggest ways to develop the education of social welfare administration. Agency evaluations and performance management has increased demands for effectiveness and accountability of social service agencies, which also has increased the roles of managers in social service agencies. Using 'Korean Social Worker Survey' conducted by Korean Association of Social Workers, this study examines job characteristics of 2,479 social workers. The results show that administration/management activities take about 40% of social workers' daily activities. Community organization, human resource management, and planning/financial management are regarded as more important and difficult than other tasks. However, sufficient education for preparing students as social service managers is not provided in undergraduate and graduate level of college education. In addition, social workers make their life long careers as managers. Thus, the education of social welfare administration needs to refocus on the provision of knowledge and skills required for competent social service managers. This study suggests future directions for developing education of social welfare administration in undergraduate and graduate level of college education including field practice.

The characteristics of the flow processes in the cylinder of the two-stroke cycle engines have become the subject of increasing and attention owing to the simplicity and the higher power per unit weight of the two-stroke cycle engine. Among the many factors which influence on the scavenging flow, the port angle is important factor. Hence, four different type models with one inlet-port and two side-ports are studied to show the effect of port angle on the laminar scavenging flow. When the inlet-port axial is relatively larger than the side-port axial angle, it is showed that the fresh charge penetrate into the burned gas and displace it first toward the cylinder head and then toward the exhaust port. When the inlet-port axial angle is much less than the side-port axial angle, the fresh charge through the inlet-port directly move toward the exhaust port. The result showed that the model A may suppress the generation of vortices in the vicinity of inlet and side prots which restrict the sufficient supply of fresh charge and obstruct the perfect displacement of all combustion products.

Administrative agencies today are paying keen attention to big data analysis to improve their policy responsiveness. Of all the big data, news articles can be used to understand public opinion regarding policy and policy issues. The amount of news output has increased rapidly because of the emergence of new online media outlets, which calls for the use of automated bots or automatic document classification tools. There are, however, limits to the automatic collection of news articles related to specific agencies or departments based on the existing news article categories and keyword search queries. Thus, this paper proposes a method to process articles using classification glossaries that take into account each agency's different work features. To this end, classification glossaries were developed by extracting the work features of different departments using Word2Vec and topic modeling techniques from news articles related to different agencies. As a result, the automatic classification of newspaper articles for each department yielded approximately 71% accuracy. This study is meaningful in making academic and practical contributions because it presents a method of extracting the work features for each department, and it is an unsupervised learning-based automatic classification method for automatically classifying news articles relevant to each agency.

Public agencies and local governments have been installing CCTV cameras for the prevention of crime, traffic jam, and unauthorized waste. Additionally, national government agencies and schools, a special corporation by special law, local construction and industrial company installed CCTV cameras of their own and are operating them. Various types of CCTV systems disclosed technical heterogeneity. In February, 2011, Ministry of Public Administration and Security presented guidelines for building an integrated control center. This study examines the case of Busan by using the administrative guidelines. Busan integrated CCTV control center among themselves, police agency and fire department. This study looks into the potential problems with the integration process of CCTV cameras and proposes a solution to them.

This article explores the influence of the king in the Joseon dynasty's document transmission system, focusing on some exceptional cases. According to the Joseon's law, the form of official documents depended on rank differences between receiver and sender. However, there were cases of not following the general principles such as Byungjo(兵曹), Seungjeongwon(承政院) and Kyujanggak(奎章閣). Byungjo was a ministry in charge of military administration. Seungjeongwon was a royal secretary institution which assisted the king and delivered king's orders that existed from the early Joseon. Kyujanggak was a royal library and an assistant institution of the king that was established in the JeongJo(正祖) era. Byungjo was regarded as a relatively high-ranking institution when it sent and received military-related documents. Seungjeongwon and Kyujanggak could use Kwanmoon(關文) to upper rank institution. Kwanmoon was the document form used for institutions of the same or lower rank than itself. Conversely, higher rank institutions used Cheobjeong(牒呈) which was stipulated as a document form to using upper rank institution in law to send them. The reason that they could have privileges in transmission document system was that Joseon had an administrative system centered on the king. Byungjo was an institution entrusted with military power from King. Seungjeonwon and Kyujanggak took charge of the assistance and the delivery of King's order. so they could have a different system of receiving and sending document than the others. In conclusion, the Joseon Dynasty operated exceptions in document administration based on the existence of the king, it means Joseon's transmission document system was basically operated under the Confucian bureaucracy with the king as its peak.
