현재 활용되고 있는 대부분의 BIM체계는 설계 및 시공단계의 작업 현상에 대한 시각적 정보제공에 초점을 두고 있는 수동형 BIM (Passive BIM) 운영체계이다. 수동형 BIM체계에서는 설계성과품의 간섭발생 부위를 3D객체에 의해 시각적으로 파악할 수 있으나, 추가적으로 간섭 상황의 해결방안을 제시하는 것은 곤란하다. 또한 시공단계 4D시뮬레이션도 일정별 시공형태의 표현은 가능하나, 프로젝트 공정조건을 고려한 최적화된 일정계획의 제시 등은 미흡한 수준이다. 그러나 최근 다양한 기관에서 BIM을 적용하면서 사용자의 BIM 요구수준은 이미 시각적 정보제공을 넘어서, 파악된 문제 현상의 해결방안까지 BIM으로 표현할 수 있는 능동형 BIM (Active BIM) 기능들을 요구하고 있다. 본 연구에서는 능동형 BIM의 개념적용을 위해 시공단계의 대표적 BIM 도구인 4D CAD시스템을 예로 하여 능동형 기능 구성방법론을 제시하고 독자적 개발엔진으로 시스템 구현을 시도하였다.

연관규칙 탐사는 지지도와 신뢰도를 바탕으로 연관성 있는 강한 항목들을 탐사한다. 탐사된 연관규칙은 장바구니 분석 등과 같이 전자 상거래 및 대형 소매점 등의 판매 패턴에 대한 분석에 유용하게 적용될 수 있다. 이와 같은 연관규칙 탐사는 대규모로 축적되어 트랜잭션 데이터를 대상으로 하는 기법으로서 대규모 데이터에 대한 반복적 스캔연산을 수반한다. 그러므로 매우 높은 연산 부하를 안고 있으며 이로 인해 동적 환경에서 실시간 제한사항을 탐사에 대한 시도를 하지 못하고 있다. 따라서 이 논문에서는 연관규칙 탐사의 비 실시간적 제한사항을 위하여 트리거와 점진적 갱신 기법을 이용한 능동적 후보항목 관리 모델을 제안하였다. 아울러 제안 모델을 구현하기 위해 점진적 갱신 기법을 이용한 능동적 후보항목 관리 모델을 제한하였다. 아울러 제안 모델을 구현하기 위해 점진적 갱신 연산의 구현 모델을 제시하고 이의 구현 및 실험을 통해 성능 특성을 분석하였다.

The purpose of this study was to investigate the impact of lifestyle on the perceived value of children in university students. Questionnaires were distributed to 467 university students with questions covering topics including general personal information and characteristics, lifestyle type, and value of children. First, a cluster analysis based on lifestyle showed that the subjects could be categorized into three groups: negative-leisure types, active-achievement types, and affirmative-fidelity types. The negative-leisure type was highly leisure-oriented and showed a negative self-value; the active-achievement type showed a perspective that valued personal and occupational self-development and a high level of labor-oriented value; and the affirmative-fidelity type favored materialism, seeking occupational aptitude and worth and showing a positive self-value. Second, an investigation of the impact of these three lifestyle types on the students' value of children revealed that the active-achievement type group had high level of belief in the necessity of childbirth, the affirmative-fidelity type group highly valued fulfilling an active parent role, and the active-achievement type group were inclined to delay childbirth. Further, the negative-leisure type group wanted the lowest number of children, while the affirmative-fidelity type group wanted the highest number of children. This study reveals that university students' lifestyle does have an effect on their value of children. It is therefore proposed that a value-focused population education for increasing fertility should relate not only to individuals' value of children but also to their broader lifestyle.

In this paper, we introduce and analyze a feedback control model of TCP/AQM dynamics. Then, we propose the Pro-active Queue Management (PAQM) mechanism, which can provide proactive congestion avoidance and control using an adaptive congestion indicator and a control function for wide range of traffic environments. The PAQM stabilizes the queue length around a desired level while giving smooth and low packet loss rates independent of the traffic load level under a wide range of traffic environment. The PAQM outperforms other AQM algorithms such as Random Early Detection (RED) [1] and PI-controller [2]

In this letter, we propose a new online buffer management algorithm to simultaneously provide diverse multimedia traffic services and enhance network performance. Our online approach exhibits dynamic adaptability and responsiveness to the current traffic conditions in multimedia networks. This approach can provide high buffer utilization and thereby improve packet loss performance at the time of congestion.

In 2014, Seongnam municipal government announced Sanseongro Commercial Area Revitalization including Dandae traditional market with active support of Seongnam municipal government. This study investigated conversion of Dandae market into specialized market to overcome economic stagnation and to make success case of wedding market. The study suggested supplementation of current problems as well as incidental businesses. The study gave SWOT analysis and management reformation to make success case of specialized market and to suggest win-win strategies and development plans to produce wedding market.

Patients with uncontrolled pain may become tired, depressed, angry, worried, lonely, and stressed. In contrast, proper management of cancer pain allows patients to be more active, sleep better, enjoy family and friends, improve their appetite, enjoy sexual intimacy, and prevent depression. Pain control is strongly influence to quality of life of cancer patients. This review discusses the importance of quality of life in pain management for cancer patients.

We explore technology ecosystem of smart surgical medical system by analyzing patent data applied for in Korea and Japan. First, a review of trends of patent application by country/technological domain show that there exist a minority of technology domains focused on R&D, which represent their trends have been increasingly active. Also, while a number of Japanese firms mainly consist of the patent market of Japan, in case of the Korean market, a few universities, SMEs, and foreign firms are found to be the main applicants. As a result of the network analysis with the links as the relations of co-patenting, the relationships, which are active of convergence and knowledge spillover among the heterogeneous technology domains within each market, as well as the technology domains, which are the most active in international cooperation among each homogeneous domain, could get derived and visualized in the ecosystem. In addition, the technology domains in each patent market with leading locations, roles, and influence in the network can also be identified through the centrality analysis. In this study, the analysis for technology competitiveness are carried out focusing on patent activity and patent impact. The results denote that across all domains, the Japanese market may possess higher patent activity and patent impact compared to the Korean market. In consequence, we derive the position map for comparison by country and technology domain from a perspective considering comprehensively the multi-dimensional attributes based on the results of both network analysis and technology competitiveness.

What government does/fails to do is conveyed to the public largely by records and information of various types in the public service, without which there will be no government. When records are poorly managed, much time is involved in sorting and locating needed information from large volumes of records. The rate of records misplaced or lost from which useful information for decision making is usually obtained makes it difficult to provide concise and up-to-date records of both past and present operations, raising the challenge of effective record-keeping. Thus this study examined records management practices in selected local government councils in Ogun State, Nigeria, adopting the descriptive survey research method using questionnaires for data collection. Its population comprised 415 records of personnel in the selected councils, of which 208 were sampled using simple random technique. From the 208 copies of the questionnaire administered on the registry personnel, 150 copies were useable, with a 72.12% response rate. Descriptive statistics were used for the analysis. The results indicated a prevalence of paper as the dominant medium for recording/conveying information in the councils with most of these being either in active state, semi-active, and vital and were kept and maintained in the registry, while in-active records were kept in the records store. Storage facilities for record-keeping were insufficient. Security measures against unauthorized access to records were by restrictions and subject users to managerial clearance. The study concluded that council records were in chaos and recommended the formulation of coherent records management policy, adequate budgetary provision, and adequate finance.

기업의 경영혁신활동을 통해 경영성과를 개선하는 방법으로 TPM프로그램의 도입은 제조업뿐만 아니라 서비스 부문을 포함하여 전 분야에 활용하고 있다. 본 연구는 생산성 향상을 위한 TPM 프로그램의 활동요인들과 경영성과와의 관계를 이론적인 모형으로 제시하고, 활동요인들이 매개변수를 통해 경영성과에 미치는 효과를 규명해 보고자 한다. TPM 프로그램을 실시하고 있는 국내 300여 기업체를 선정하여 설문조사를 하였으며 설문지 문항의 타당성과 신뢰도를 검토하기 위하여 탐색적 요인분석과 확인적 요인분석을 실시하였고, 대상자의 특성을 알아보기 위하여 빈도분석을 하였다. 요인분석과 빈도분석은 SAS 8.2 version의 통계프로그램을 이용하였고 연구모형을 검증하기 위하여 LISREL 8.52 version을 사용하였다. TPM 프로그램의 활동요인들은 '자주보전', '개별개선', '계획보전', '교육 및 훈련'의 네 요인으로 구성하였다. 4개의 활동요인들 중에서 특히 개별개선과 교육 및 훈련이 설비효율과 조직 및 인적관리에 큰 영향을 미치고 설비효율과 조직 및 인적관리 중에서는 조직 및 인적관리가 경영성과에 큰 영향을 미치는 것으로 나타났다. 따라서 TPM프로그램의 활동을 통해서 경영성과를 향상시키기 위해서 종업원에 대한 교육훈련이 가장 중요하고 다음으로 개별개선활동이 중요한 것으로 나타났다.
