This article reviews the art and practice of strategic management process in hospitals today, in order to help hospital administrators for managing strategic management system in their hospitals. The strategic management process model in this article is based on an integrated approach combining traditional environmental model with resource-based model of strategy. The components of the model are consisted of five steps: (1)formulating objectives, strategic assessment by external environmental analysis, internal capability analysis, TOWS analysis and marketing audit, (3)strategy choice considering context and criteria of choice, (4)program implementation through operational planning, resource allocation, and conversion, and (5)control by monitoring and evaluating hospital outputs. This article deals with many aspects of issues inherent in every step on this strategic management process.

M&S 및 SBA의 지속적 발전을 위해서는 성숙도 측정모형의 개발이 매우 중요한 사안이다. 성숙도 측정모형은 일반적으로 각 분야에 밀접하게 연관된 조직의 프로세스 수행 능력 혹은 조직 자체의 성숙도를 측정하고 지속적인 프로세스 개선 및 조직의 발전을 위한 기준을 제시한다. 또한 성숙도 모형은 성숙도를 정량적 지표로 환산하기 위한 참조모형과 실제로 대상 조직 혹은 프로세스에 대한 능력을 정량화하여 심사하는 모형으로 구성된다. 본 논문에서는 기 개발된 SBA 성숙도 측정모형의 기준모형을 간략히 소개하고 여러 가지 성숙도 심사 방법론을 고찰하여 SBA 성숙도 심사 방법론의 프레임워크를 마련하고자 한다.

본 논문은 기존의 총 송전용량 결정에 있어서 고려하기 어려웠던 과도 안정도 제약을 판별법을 적용하기 위해 2단계 계산 기법을 이용하여 보다 용이하게 적용하였다. 총 송전용량을 계산하기 위한 방법으로 첫 번째 단계에서는 RPF(Repeated Power Flow) 방법을 이용하여 전압과 열적한계를 판별하고, 두 번째 단계에서는 첫 번째 단계에서 결정된 총 송전용량이 시스템의 과도 안정도 조건의 위반여부를 판별하여 시스템의 총 송전용량을 결정하였다.

House load operation (HLO) occurs when the generator supplies power to the house load without triggering reactor trips during grid disturbances. In Korea, the HLO capability of optimized power reactor 1000 (OPR1000) plants has prevented several reactor trips. Operational experiences demonstrate the difference in the reactor trip incidence due to grid disturbances between OPR1000 plants and Westinghouse plants in Korea, attributable to the availability of the HLO capability. However, probabilistic safety assessments (PSAs) for OPR1000 plants have not considered their specific design features in the initiating event analyses. In an at-power PSA, the HLO capability can affect the initiating event frequencies of general transients (GTRN) and loss of offsite power (LOOP), resulting from transients within the grid system. The initiating event frequencies of GTRN and LOOP for an OPR1000 plant are reduced by 17.7% and 78.7%, respectively, compared to the Korean industry-average initiating event frequencies, and its core damage frequency from internal events is reduced by 15.2%. The explicit consideration of the HLO capability in initiating event analyses makes significant changes in the risk contributions of the initiating events. Consequently, for more realistic at-power PSAs in Korea, we recommend incorporating plant-specific HLO-related design features when estimating initiating event frequencies.

In-place analysis for offshore platforms is essentially required to make proper design for new structures and true assessment for existing structures. The structural integrity of platform components under the maximum and minimum operating loads of environmental conditions is required for risk assessment and inspection plan development. In-place analyses have been executed to check that the structural member with all appurtenances robustness and capability to support the applied loads in either storm condition or operating condition. A nonlinear finite element analysis is adopted for the platform structure above the seabed and the pile-soil interaction to estimate the in-place behavior of a typical fixed offshore platform. The analysis includes interpretation of dynamic design parameters based on the available site-specific data, together with foundation design recommendations for in-place loading conditions. The SACS software is utilized to calculate the natural frequencies of the model and to obtain the response of platform joints according to in-place analysis then the stresses at selected members, as well as their nodal displacements. The directions of environmental loads and water depth variations have important effects on the results of the in-place analysis behavior. The result shows that the in-place analysis is quite crucial for safe design and operation of offshore platform and assessment for existing offshore structures.

Based on the results of Probabilistic Safety Assessment(PSA) for a Nuclear Power Plant (NPP), Common Cause Failure(CCF) events have been recognized as one of the main contributors to the risk. Also, the CCF data and estimation method used in domestic PSA models have been pointed out as an issue with respect to the quality. The existing method of MGL and non-staggered testing even widely used were considered conservative in estimating the safety and had a limited capability in uncertainty analyses. Therefore, this paper presents the CCF estimation using a new generic data source and Alpha factor method. The analyses showed that Alpha factor and staggered method are effective in estimating the CCF contribution and risk insights of reference plant. This method will be a common bases for the optimization of new design for the construction plants as well as for the updating of safety assessment on the operating nuclear power plants.

컴퓨터 교육은 지식의 이해 정도뿐만 아니라 사고력, 판단력, 문제 해결 능력 등이 강조되기 때문에 실천적인 태도와 기술적인 활동의 체험이 중요시되므로 학습자에 대한 평가는 학습내용의 기술적인 실기 능력, 적용 능력, 적극적인 태도 등이 균형있게 평가되어야 한다. 따라서 본 연구는 컴퓨터교육에서 지향해야 할 평가의 방향으로 문제해결 과정 중심의 평가와 학생 참여적인 객관적인 평가를 제시하고 그것을 평가할 수 있는 방법을 제안하였다. 그리고 평가 실험을 통하여 제안된 방법이 기존의 수행평가 방법으로는 얻을 수 없었던 학생의 수행능력을 평가할 수 있음을 보였다.

Lately, the management of domestic BIM performance is quite lacking, as the evaluation and management data from successful cases of BIM implementation both on projects and in companies, and related effects (time, cost and other physical gains) are not well kept for future use in BIM development. In order to overcome the above obstacles, a systematic approach to evaluating BIM adoption with focus on particular elements like BIM implementation environment and processes, and the physical factors yielded by BIM, is necessary. In this study, objective and detailed assessment indicators and weights that are appropriate for the domestic situation were derived through research for purposes of developing a web-based BIM maturity measurement program that is tailor-made for the Korean construction atmosphere. Through a company's self-maturity measurement, excellent quality of BIM deliverables and output can be achieved and managed. Furthermore, the domestic BIM capacity can gradually increase since design firms' BIM capability can be judged during procurement basing on measurement indicators.
