Little empirical study has been conducted concerning board function effectiveness and organizational performance in nonprofit nongovernmental human service organizations in Korea. Using the evaluations of 107 board members and 17 executive directors in Korean Community Chest and 16 regional community chests, this study attempted to examine the level of board function effectiveness and its relationship with organizational performance in these community chests. This study used board function scale developed by Holland and Jackson (1998) to measure board function effectiveness in the following 6 dimensions: contextual dimension: educational dimension: interpersonal dimension: analytical dimension: political dimension: and strategic dimension. This study showed that using 4 points scale, mean of overall board function effectiveness evaluated by board members is 2.62 and mean of overall board function effectiveness evaluated by executive directors is 2.73. That is, it showed that means of overall board function effectiveness are located in the middle point between negative evaluation and positive evaluation. On the other hand, using parametric correlation analysis method, it was found that in these community chests the association between board function effectiveness and organizational performance measured by fund-raising growth rate in $1999{\sim}2000\;and\;1998{\sim}2000$ is very weak and statistically nonsignificant. This study also revealed that using nonparametric correlation analysis method, the association between consensus level in evaluation by board members and executive directors about board function effectiveness, and organizational performance is still very weak and statistically nonsignificant. Finally, this study discussed the direction of future research in board function effectiveness and its relationship with organizational performance and the areas of board management that requires substantial efforts for promoting effectiveness of nonprofit human service organizations in Korea.

최근, NCW에 적합한 C4I 체계의 전투력 상승효과 평가의 필요성이 제기되고 있다. 기존의연구는 체계 자체에 중점을 두었으며, 인적 요소를 중요한 요소로 고려하지 않았다. 따라서, C4I 체계의 전투력 상승효과 평가 시 기술 및 인적 요소를 고려하여 평가하는 것이 필요한 시점이라고 할 수 있다. 이에 본 연구에서는 E-TechMan(A Combat Effectiveness Evaluation Algorithm Considering Technical and Human Factors in C4I System)이라 불리는 전투력 상승효과 평가 알고리즘을 제안한다. E-TechMan 알고리즘은 합동화력체계(Joint Fire Operating System-Korea)에 적용되어 전투력 상승효과를 평가해보았다. 또한, 기존의 연구방법인 C2 이론 및 고전 역학에 의한 결과와 비교를 하였다. 본 연구는 인적요소에 의한 영향을 반영함으로써 기존의 연구보다 현실적인 전투력 상승효과 결과를 제시했다는데 가치가 있다.

본 논문은 시뮬레이션을 이용한 DDoS공격 대응기술의 효과성을 평가하기 위한 방법을 제시한다. 미국 국가표준기술연구소(NIST: National Institute of Standards and Technology)에서 제시한 보안목표에 따라 효과성평가모형을 계층적으로 표현하였다. 보안목표, 보안통제, 성과지표에 해당하는 요인들의 가중치 계산을 위해 계층적 분석(AHP: Analytic Hierarchy Process)을 적용하고, 최하위계층인 성과지표의 기능점수계산을 위해 Arena시뮬레이션모델을 구현하였다. 탐지 및 차단 알고리즘은 네트워크 L4, L7계층 공격에 대한 임계치설정, 시그니쳐기반탐지, 행동(통계)기반탐지 기술을 복합적으로 검증하였다. 제안된 효과성평가모형은 조직마다 상이한 보안목표와 위협에 따라 다르게 설계될 수 있으므로 새로운 보안위협에 대한 대응방안이나 대응기술의 효과성을 평가할 수 있는 방법으로 활용될 수 있다.

This paper presents cost-effectiveness evaluation of semi-active control system for cable-stayed bridge under earthquake excitation. Bi-state control method with Linear Quadratic Gaussian(LQG) optimal controller is used for generic semi-active dampers. Cost-effectiveness of the structural control system is investigated by using the life-cycle cost(LCC) concept. The evaluation results show that the efficiency of semi-active control system is increased when the damage cost due to the failure of bridge system or the bridge importance is enlarged. It was also found that the damper cost had little influence on the cost-effectiveness of semi-active control system if it was relatively small to the initial construction cost.

The purpose of this study is to suggest the evaluation standard of cost-effectiveness analysis for renew of architectural equipment in public building. Evaluation items of cost-effectiveness analysis for renew of architectural equipment in public building were used life cycle cost, energy consumption(ton of oil equivalent), green house gas emissions(ton of carbon dioxide) and maximum power demand. Life cycle cost is the process of making an economic assessment of an item, area, system, or facility by considering all significant costs of ownership over an economic life, expressed in terms of equivalent costs. The essence of life cycle costing is the analysis of equivalent costs of various alternative proposals. The social concern with green house gas and maximum power demand of architectural equipment field has been growing for the last several years.

In this study, the evaluation items related to the effectiveness evaluation of the LVC (Live, Virtual, Constructive) training system of the Air Force were derived and the weights of each item were analyzed. The LVC training system evaluation items for AHP (Analytic Hierarchy Process) analysis were divided into three layers, and according to the level, 3 items were derived at level 1, 11 items at level 2, and 33 items at level 3. For weight analysis of evaluation items, an AHP-based pairwise comparison questionnaire was conducted for Air Force experts related to the LVC training system. As a result of the survey, related items such as (1) Achievement of education and training goals (53.8%), (1.2) Large-scale mission and operational performance (25.5%), and (1.2.1) Teamwork among training participants (19.4%) was highly rated. Also, it was confirmed that the weights of evaluation items were not different for each expert group, that is, the priority for importance was evaluated in the same order between the policy department and the working department. Through these analysis results, it will be possible to use them as evaluation criteria for new LVC-related projects of the Air Force and selection of introduction systems.

미래전이 네트워크중심전(NCW, Network Centric Warfare)으로 변화함에 따라 세계적으로 지휘통제의 효과도에 관한 관심이 점증하고 있다. 과거의 기동과 타격자산 중심의 소모전 위주의 전투와 달리, 현대전은 정보의 획득과 유통이 중요시되는 정보 네트워크 기반의 전쟁으로서 C4ISR(Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance) 체계가 핵심적인 역할을 담당할 것이라는 데는 재론의 여지가 없다. 그럼에도 불구하고 지휘통제가 전투에 기여하는 효과의 정도를 측정하는 방법론이나 효과 반영체계 등을 명확하게 설명할 방법을 갖추고 있지 못한 실정이다. 본 연구에서는 네트워크중심작전의 기반이 되는 C4ISR 체계에 의한 효과도 증진을 개념적으로 설명할 수 있는 프레임워크인 미국방부가 개발한 NCO-CF(Network Centric Operations-Conceptual Framework)에 대하여 살펴보았다. 그리고 NCO-CF를 기반으로 하여 지휘통제 효과도 모의분석을 위한 평가기준을 도출하기 위한 방법론을 제시하였다. 사례연구로 합동작전의 지휘통제 체계에 이 방법론을 적용하여 모의분석을 위한 평가기준을 도출하였다.

Economic evaluations in the healthcare are used to assess economic efficiency of pharmaceuticals and medical interventions such as diagnoses and medical procedures. This study introduces the main concepts of economic evaluation across its key steps: planning, outcome and cost calculation, modeling, cost-effectiveness results, uncertainty analysis, and decision-making. When planning an economic evaluation, we determine the study population, intervention, comparators, perspectives, time horizon, discount rates, and type of economic evaluation. In healthcare economic evaluations, outcomes include changes in mortality, the survival rate, life years, and quality-adjusted life years, while costs include medical, non-medical, and productivity costs. Model-based economic evaluations, including decision tree and Markov models, are mainly used to calculate the total costs and total effects. In cost-effectiveness or costutility analyses, cost-effectiveness is evaluated using the incremental cost-effectiveness ratio, which is the additional cost per one additional unit of effectiveness gained by an intervention compared with a comparator. All outcomes have uncertainties owing to limited evidence, diverse methodologies, and unexplained variation. Thus, researchers should review these uncertainties and confirm their robustness. We hope to contribute to the establishment and dissemination of economic evaluation methodologies that reflect Korean clinical and research environment and ultimately improve the rationality of healthcare policies.

본 연구에서는 광고평가글을 이용해 광고효과를 측정할 수 있는지 살펴보고자 하였다. 이를 위해 온라인을 통해 연구에 참여한 대학생 384명을 대상으로 고관여와 저관여 제품의 긍 부정 평가 광고에 대한 광고평가를 자기보고식으로 측정하고, 광고평가글을 작성하도록 하였다. 작성된 광고평가글을 KLIWC으로 분석하여 긍 부정 평가 광고 간의 차이를 살펴보았다. 분석결과, 심리사회적 변인들 중 17개 변인들에서 긍 부정 광고 간에 유의미한 차이가 나타났으며, 9개의 언어학적 변인들에서 긍 부정 광고 간에 유의미한 차이가 나타났다. 또한 긍정정서, 부정정서, 제한, 확신, 신체상태와 기능, 수면/꿈 등은 광고태도, 제품태도, 구매의도와 유의미한 상관이 나타났다. 본 연구는 광고평가글이 광고에 대한 소비자의 심리적 반응을 반영하고, 광고평가글을 통한 광고효과 측정이 가능함을 시사해주고 있다.
