전 세계적으로 약물 부작용은 주요 사망원인의 상위를 차지하고 있다. 약물 부작용에 대해 효과적으로 대응하기 위해, 능동적인 실시간 분석 기반 약물감시 체계로의 전환과 함께 데이터의 표준화와 품질 향상이 필요하다. 이를 위해, 개별 기관의 데이터를 통합하고 대규모 데이터를 활용하여 약물 부작용 예측의 정확도를 높이는 것이 중요하다. 하지만, 각 기관 간의 데이터 공유는 프라이버시 문제를 야기시키고 각기 다른 데이터 표준 구성도 다르다. 본 연구에서는 이 문제를 해결하기 위해, 개인정보보호 법규에 따라 데이터를 직접 공유하지 않고 모델의 학습 결과를 공유하는 연합학습 방식을 채택한다. 각 기관마다 다른 데이터포맷을 Common Data Model(CDM)을 활용하여 데이터 표준화를 수행하고 데이터의 정확성과 일관성을 확립한다. 또한, 클라우드 기반의 연합학습 환경을 구성하여 보안 및 확장 관리에 효율성을 높이는 약물감시 시스템을 제안한다. 이를 통해 기관 간 데이터의 프라이버시를 보호하면서도, 효과적인 의약품 부작용 모니터링과 예측이 가능하다. 약물 부작용으로 인한 사망률 감소와 의료비용 절감을 목표로 하며, 이를 실현하기 위한 다양한 기술적 접근과 방법론을 탐구한다.

The importance of effective communication is increasingly stressed in the medical sector. This is crucial for the resolution of medical accidents and conflicts, and that can contribute to the prevention of the two as well. The careful attitude of the medical team toward patient safety and their communication with colleagues and other departments are mandatory for the successful decrease of dental accidents. The good communication within of the hospital organization is one of vital ways to ensure accurate diagnosis and successful treatment. In the field of health care, effective teamwork requires a shared goal, superb work skills, communication and cooperation, but this fact has been overlooked so far. Among those factors, communication is indispensable to the achievement of organizational goals, and how to boost communication by acquiring diverse skills and using appropriate tools in the dentistry should discreetly be considered. This study explared how to improve the teamwork and communication of organization in an effort to seek specific ways of reducing medical conflict in dental.

The purpose of this research is to find applicable design characteristics of communal spaces in multi-family houses. With this goal, international multi-family housing projects are selected and their communal spaces are identified. The purpose of study lies in analyzing on recent 10 years trends of shared space of multi-family houses in Europe, Japan, central America. The design characteristics of the communal spaces are analyzed with a special focus on the four Aspects such as Organization of space, access roads, parking, pedestrian movement In terms of the framework for analysis, community, rest, separability, rambling, territory, distribution, entrance, openness, view, prospect and aesthetic characteristics are reviewed. As a result, the communal space of the analysis are integrated in plans and sections throughout the multi-family houses. Openness and connection with surrounding urban environments are articulated by communal spaces. Communal identities and aesthetics are emphasized by various space for dweller and the other inhabitant. For a further research, it is necessary to combine a design method study with new multi-family houses for the future.

This paper is concerned with a parallel system that sustains a time-independent load and consists of n components with exponential lifetimes. It is assumed that the total load is shared by the working components and the failures of components increase higher failure rates in the surviving components according to the relationship between the load and the fialure rates. The power rule model among several load-failure rate relationships is considered. We consider the system efficiency meausre as the expected profit earned by the system per unit time. The high load causes high gain but it also occurs frequent system failures. The expected profit per unit time is used as criterion to evaluate the system efficiency. The goal of system engineer is to determine the optimal load and redundant units maximizing the expected profit per unit time. First, the system reliability function is obtained and the optimization problem of the load-sharing parallel system is considered. Given the redundant units, the existence of the optimal load can be proved analytically and given the load, the optimal redundant units can be solved also analytically. The optimal load and redundant units are obtained simultaneously by numerical computation. Some numerical examples are studied.

The goal of this study was to identify and characterize selected Trichoderma isolates by metabolic profiling and enzyme assay for evaluation of their potential as biocontrol agents against plant pathogens. Trichoderma isolates were obtained from the Rural Development Administration Genebank Information Center (Wanju, Republic of Korea). Eleven Trichoderma isolates were re-identified using ribosomal DNA internal transcribed spacer (ITS) regions. ITS sequence results showed new identification of Trichoderma isolates. In addition, metabolic profiling of the ethyl acetate extracts of the liquid cultures of five Trichoderma isolates that showed the best anti-Phytophthora activities was conducted using gas chromatography-mass spectrometry. Metabolic profiling revealed that Trichoderma isolates shared common metabolites with well-known antifungal activities. Enzyme assays indicated strong cell wall-degrading enzyme activities of Trichoderma isolates. Overall, our results indicated that the selected Trichoderma isolates have great potential for use as biocontrol agents against plant pathogens.

Objectives: The goal of this study was to estimate the overall satisfaction level of dental implant patients and further evaluate factors influencing satisfaction. Materials and Methods: Self-administered questionnaires were mailed to patients who received dental implant therapy at Seoul National University Bundang Hospital (Seongnam, Korea) from October 2003 to April 2005. The main portion of the questionnaire was shared to evaluate the level of satisfaction with implant therapy. The questionnaires contained evaluations of influencing factors, which were classified as pain-related, service-related, and complication-related. Results: The responses from 93 patients (41 males, 52 females) with a total of 325 implants were included in the analysis, and the mean score for overall satisfaction level with implant therapy was 8.26. Female patients showed higher visual analogue scale (VAS) scores for both pain during (P=0.000) and after implant surgery (P=0.016). Male patients showed more 'negative' values for the reasonability of treatment cost (P=0.008) and the adequacy of the treatment period (P=0.022). Conclusion: The subjective satisfaction of patients was influenced by various factors, especially complication-related factors.

본 논문은 최근 급성장하고 있는 공유경제플랫폼에 대한 바람직한 규제 방안을 논하고 있다. 디지털 기술의 발전과 혁신은 새로운 서비스, 새로운 경제, 산업 가치의 창출이라는 기대도 큰 반면, 기존 산업과의 이해 충돌에서 발생하는 사회적 신뢰 문제에 대한 우려와 도전, 과제들을 야기한다. 공유경제 역시 새로운 수요와 공급을 창출하고 혁신적인 거래방식으로 전 세계적으로 빠른 성장을 하고 있지만, 아직도 주요 도시에서는 기존 산업 가치와의 충돌이 야기하는 문제에 대해 제도적 측면에서의 한계점이 노출되고 있다. 본 연구는 이러한 문제점을 최소화하기 위해 일정 수준의 규제가 필요함을 전제로 규제과정에서 수반되는 사회적 비용 최소화를 위해서 공유경제 특성을 고려한 공동규제(Co-regulation) 접근방안이 바람직함을 제안하고 있다.

Given that various classroom contextual factors influence the nature of writing instructional practices, it would be worthwhile to explore these factors to generate better environment for learning to write. Among many factors, this study examined teachers' beliefs and knowledge, which would operate as a very influential contextual factor in that changes in principles and methods of teaching writing would be the results of their underlying beliefs and knowledge related to teaching writing. Three professional teachers who teach second- and third-grade English language learners (ELLs) were interviewed, and the analysis of teacher interviews was conducted. The research findings indicated that basically all of the teachers perceived the role of writing in second language learning as very important, sharing the belief that the ultimate goal of teaching writing is to have their students gain fluency in writing and that some of instructional methods such as integration of writing and other language aspects, content-based writing, and providing scaffolding are important. In addition, some beliefs that two ESL teachers shared included the importance of ample and continuous opportunities to write, vocabulary knowledge, and explicit instruction about writing. Other beliefs, including the importance of creating a comfortable writing environment and opportunities for writing for varied purposes and genres were represented.
