In this paper, we developed the semiconductor monitoring system for the etching process. Around the world, expert companies are competing fiercely since the semiconductor industry is a leading value-added industry that produces the essential components of electronic products. As a result, many researches have been conducted in order to improve the quality, productivity, and characteristics of semiconductor products. Process monitoring techniques has an important role to give an equivalent quality and productivity to produce semiconductor. In fact, since the etching process to form a semiconductor circuit causes great damage to the semiconductors, it is very necessary to develop a system for monitoring the process. The proposed monitoring system is mainly focused on the dry etching process using plasma and it provides the detailed observation, analysis and feedback to managers. It has the functionality of setting scenarios to match the process control automatically. In addition, it maximizes the efficiency of process automation. The result can be immediately reflected to the system since it performs real-time monitoring. UI (User Interface) provides managers with diagnosis of the current state in the process. The monitoring system has diverse functionalities to control the process according to the scenario written in advance, to stop the process efficiently and finally to increase production efficiency.

OSC is drawing attention to supplement limitations such as productivity problems and on-site safety and quality problems of existing on-site labor-oriented construction production methods. In order to activate the introduction and use of OSC in the domestic construction market, it is important to innovate the technology applied to each stage of OSC process (design and engineering, factory manufacturing, site assembly, and maintenance), but it is also necessary to develop a project management method suitable for OSC method. However, research related to OSC currently being conducted in Korea is mainly in terms of related technology development, and research on deriving project management measures for the success of OSC projects is insufficient. Therefore, it is time for research on deriving a project management plan based on the core success factors of the OSC project. Therefore, by conducting importance-performance analysis on 69 OSC critical success factors derived from the previous study, the study was conducted to derive key improvement factors for OSC introduction and utilization improvement and to provide implications for this. The results of this study are expected to have useful implications for the R&D planning and policy-making process for OSC activation in the future.

The oak-mushroom is one of the special minor products utilizing hardwoods, such as oaks in the mountaineous villages, as a food for health and export in Korea. However, oak-mushroom farmers have been faced the problems such as small cultivation scale, unskilled technique of production, management of cultivation, and low productivity. It is now a turning point presenting the optimum and reasonable management techniques to increase the productivity with consideration of balanced income and expenditure. This report analyzed the investment effectiveness of cultivation. The financial rate of return (FRR) of oak-mushroom cultivation is as high as 10.3 percent compared with that of other farmings. Moreover, the FRR remarkably increased with increased cultivation scales. The FRR could be highly improved if the price of both mushroom-logs and dried mushroom products, is stable and the cultivation techniques for higher productivity are developed. The policy providing the constant price of raw materials and mushroom products, and new advanced cultivation techniques enable the enhancement of investment for the oak-mushroom cultivation.

Semicurrent records are documents that are stored and managed in a separate section because they are infrequently referred to in work. The semicurrent records management stage is when records from the processing department are collected for the first time, serving as a bridge between the current and noncurrent records. For systematic records management, records management at the semicurrent stage is vital. Although Korea has established numerous records centers, various problems remain in the records management environment. In response, this study examines the United States' semicurrent records management system and discusses the features that are different from that of Korea. For this purpose, the records management system of the United States was selected as the scope of research and is analyzed through its records schedule, transfer, and appraisal. The data for the research were obtained through the relevant records management law, guidelines compiled by related agencies, and written inquiries for the records management officer. Through these methods, this study was able to identify the relationship between the federal agency and the Federal Records Center, the introduction of new technology in the aspect of transfers, the privatization of records preservation, and the status of the Federal Records Center as a passive appraisal entity.

Recently, interests in the notion of PKMS(Process based on Knowledge Management System) utilizing BPMS(Business Process Management System) and KMS(Knowledge Management System) have been significantly increased. Specially, most public organizations require their own effective knowledge management strategies since public business service needs various knowledge types. Based on a comprehensive framework that reflects lifecycle requirements of KMS and BPMS, we propose an PKMS system architecture, which performs step-by-step knowledge-providing strategy in public organization. To propose a PKMS architecture, this paper first investigates inter-relationships between public business and various knowledge types, and classifies knowledge types into three groups and then we suggest knowledge management strategies considering priority order among knowledge groups. Based on the proposed knowledge management, a PKMS system architecture can combine the advantages of the KM and BPM paradigms. This paper presents the PKMS system applied to employment insurance business part in real environment and demonstrated the advantages via inter-relationships between KM and BPM requirements.

Dangsan forests are traditional village forests which have been established by local residents. They represent unique cultural landscape of Korea with a history of more than several hundred years. It is necessary for a cultural contents to have locality and globality so as to represent Korea. Cultural heritage can retain their value when they are fully sustained their authenticity and management scheme. Although many Dangsan forests have been on the verge of disappearance, the four villages in Sinwon-ri have retained Dangsan forests with Dangsan ritual. In this study, a designation of 'Conservation area of agricultural landscape ecology' including Dangsan forests, Bibo forests, rice paddy field, and stream in Sinwon-ri was suggested. This 'Conservation area of agricultural landscape ecology' can be developed to unique glocal cultural content of rural Korea, and will contribute to enhance the value of the Dangsan forest's, and revitalization of rural villages.

위에서 언급한 바와 같이 계측대상 연약 지반이 대심도, 광역화함에 따라 연약지반 계측의 전반적인 추세는 자동계측 시스템의 사용과 준설ㆍ매립공사 또는 해수면상에서의 공사 특성상 케이블 관리의 어려움을 극복하고자 무선데이터 전송방식의 사용이다. 또한 유지관리의 필요성 증대로 인하여 계측 모니터링, 자동분석 프로그램의 기술도 발전되고 있다. 그러나 아직 국내는 계측에 대한 기술 개발이 미비할 뿐 아니라 계측기술에 대한 인식이 매우 부족하고, 관련법이 정비되지 못하여 계측관련 기술 및 경험이 전무한 영세업체들까지 난립하여 치열한 경쟁을 하는 관계로 기술개발에 대한 투자는 거의 중단된 상태이다. 따라서 정확한 유지관리 계측을 위해서는 대부분 외산기기에 의존할 수밖에 없는 상황이다. 그러나, 현재 국내의 전자통신 기술의 수준을 감안할 때 관련법이 정비되고 체계적인 연구와 투자가 이루어진다면 쉽게 세계적인 수준으로 도약할 수 있으리라 판단된다. 한국지반공학회의 연약지반위원회에서는 2003년 8월 20일 한양대학교 박물관 강당에서 학술세미나를 개최하였다. 본격적인 세미나에 앞서 '연약지반 공학자의 당면문제 및 해결방안'에 관한 주제로 전 연약지반위원회 위원장이셨던 (주)에스코 컨설턴트의 김승렬박사께서 초청강연을 하여 주셨다. 김승렬박사께서는 그 원고의 꼬리말을 다음과 같이 기술하며 마무리하셨다. 국내 연약지반 기술수준의 상황과 우리의 위상을 제고하기 위한 좋은 말씀으로 생각되어 본고에서는 그 부분을 인용하는 것으로 끝을 맺고자 한다. '우리나라의 연약지반 기술수준은 동남아시아 지역의 국가들인 싱가포르, 대만, 태국, 심지어는 베트남에 비해 결코 우월한 위치에 있지 않다. 오히려 많이 낙후되었다고 할 수 있다. 경제규모와 위상과 발전상태에 비추어 보면 실로 부끄러운 일이 아닐 수 없다. 이렇게 된 배경에는 연약지반이 사회의 문제로 대두되는 일이 미미하여 이 분야에 쓸리는 관심이 상대적으로 적은 점이 주원인이라고 볼 수 있다. 연약지반이 기술현장에서 문제로 떠오르기 시작한지도 째 오랜 시간이 경과하였다. 이제 더 이상 우리의 기술수준을 이대로 방치할 수는 없는 시점에 와 있는 것이다. 연약지반에 몸담고 있는 우리 스스로가 위상을 지키려는 노력을 배가하여야 한다. 연약지반 공학자들은 스스로 고급의 데이터를 생산하고 평가하고 예측하는 기법을 활발하게 적용하고 발전시킴으로써 자신들의 위치를 지켜야 할 것이다. Clean-handed-research만을 고집하는 환상에서 깨어나 국외의 변모하는 모습을 빠르게 수용하고 국내의 연약지반 관련 자료를 국외에 널리 알릴 수 있는 위치로 발돋움할 때 연약지반 공학자의 위상도 제고될 것이다.'

As the uncertainty of precipitation increases due to climate change, seasonal forecasting and the use of weather forecasts become essential for efficient water resources management. In this study, the categorical probabilistic long-term forecasts implemented by KMA (Korea Meteorological Administration) since June 2014 was evaluated using assessment indicators of Hit Rate, Reliability Diagram, and Relative Operating Curve (ROC) and a technique for obtaining quantitative precipitation estimates based on probabilistic forecasts was proposed. The probabilistic long-term forecasts showed its maximum predictability of 48% and the quantified precipitation estimates were closely matched with actual observations; maximum correlation coefficient (R) in predictability evaluation for 100% accurate and actual weather forecasts were 0.98 and 0.71, respectively. A precipitation quantification approach utilizing probabilistic forecasts proposed in this study is expected to enable water management considering the uncertainty of precipitation. This method is also expected to be a useful tool for supporting decision-making in the long-term planning for water resources management and reservoir operations.

In this paper, a dynamic warning system to forecast inland flooding associated with typhoons and storms is described. The system is used operationally during the typhoon season to anticipate the potential impact such as inland flooding on the coastal zone of interest. The system has been developed for the use of the public and emergency management officials. Simple typhoon models for quick prediction of wind fields are implemented in a user-friendly way by using a Graphical User Interface (GUI) of MATLAB. The main program for simulating tides, depth-averaged tidal currents, wind-driven surges and currents was also vectorized for the fast performance by MATLAB. By pushing buttons and clicking the typhoon paths, the user is able to obtain real-time water level fluctuation of specific points and the flooding zone. This system would guide local officials to make systematic use of threat information possible. However, the model results are sensitive to typhoon path, and it is yet difficult to provide accurate information to local emergency managers.
