This paper proposes a new software quality model composed of a hierarchy of software quality views and three software quality characteristics models. The software view hierarchy is composed of two levels : end view and means view at the first level, contingency view and intrinsic view as sub-views of means view. Three software quality characteristics models are activity quality characteristics model, contingency quality characteristics model, and intrinsic quality characteristics model, which correspond to end view, contingency view, and intrinsic view respectively. This paper also reclassifies characteristics of ISO/IEC 25000 series SQuaRE's software product quality model according to the proposed software quality model. The results illustrate clearly the shortcomings of SQuaRE's product quality model and how to overcome them. First of all, most of SQuaRE's product characteristics should be redefined and conceptually clarified according to the views on which they are really rested. Much more characteristics should be supplemented too. After that, rigorous empirical researches will become relevant. Causal relationships between activity quality characteristics and characteristics of means view should be empirically researched.

본 연구는 한국 기업의 글로벌마케팅 프로그램의 표준화-현지화 정도를 결정하는 요인에 관한 실증적 연구이다. 특히 본 연구는 2가지 관점에서 기존 연구와 차별화하고자 하였다. 첫째는 모국-현지국의 환경 차이에 초점을 두는 기존 실증연구와는 달리 글로벌 관점에서 분석하고자 하였다. 두 번째는 본 연구는 상황접근론 관점과 자원기반 관점에서 결정요인을 설정하고 이들 요인의 효과를 검증하고자 하였다. 구체적인 결정요인으로 상황적응론적 관점에서 외부환경 요인인 글로벌 시장의 역동성과 복잡성을, 그리고 자원기반 관점에서 글로벌 마케팅자산을 설정하고 검증하였다. 이를 위해 국제마케팅을 수행하는 국내 기업 128개 업체를 대상으로 설문조사를 실시하였다. 연구 결과, 기업의 글로벌 마케팅자산은 글로벌마케팅 프로그램 표준화 정도와의 정(正)의 관계를 나타는 것으로 나타난 반면에, 글로벌 시장환경 요인은 통계적으로 유의한 관계가 없는 것으로 나타났다. 이는 기업의 글로벌마케팅 프로그램은 상황적응론적 관점보다는 자원기반 관점에서 결정되는 경향이 있음을 사사하는 결과이다.

This paper presents an analysis of the voltage stability when the contingency is occured in the power system. The evaluation of voltage stability is examined by the system identification based on T/L losses and percent indicator which represents how relatively far-off from the voltage collapse. When contingency happens, the bus voltages can be calculated using the EMTP and then, the time-interval in contingency is linearized between the known operating points in nose curves. For the sample study, the 5-bus and 7-bus systems are selected and, countermeasures for the contingency are established in view of the voltage stability.

In Sanyue, the identity of the state and the individual is discussed in terms of the class, ideology, system, moral ethics, tactical strategy, national view, Talent image, etc. and It pursues a historical approach in the world history and an attempt to self-realize in the history of mankind. This literature expresses the strength of military theory and discusses the main core points of the country as a military political and tactical strategy as follows: "Shangyue, zhongyue, and Xiayue. In the Shangyue in Sanyue, it describes how to distinguish the heroes who have been appointed through the ceremony, and it shows the accomplishment of the reason. In zhongyue, we discuss how to distinguish the contingency plan the meaning of change. In Xiayue, we discuss practical thinking of moral ethics and explain the possibility of All the officials and sages angry by considering the safety of the country."

The paper analyzes reactive power flow characteristic in power system by reactive power tracing. In addition, virtual buses are inserted in the algorithm to consider losses of transmission lines, and shunt capacitor treated as a reactive power generator. The results of simulation are analyzed by two points of view. The one is load’s point of view and another is generator’s point of view. Classic purpose of the reactive power tracing consists in the reactive power pricing. However, it is significantly used to select vulnerable area about line outage in this paper. To find the vulnerable area, reactive power tracing variations between pre-contingency and post-contingency are calculated at all load buses. In heavily load area, buses which has highest variation become the most vulnerable bus. This method is applied to the IEEE 39-bus system. It is compared with voltage variation result and VQ-margin to verify its effect.

예비비의 산정은 건설공사에서 필연적으로 발생할 수뿐이 없는 예측불가능한 상황으로 인한 공사비의 증가와 공기의 연장에 대처하기 위해서이다. 예비비의 본 취지는 불확실한 요소로 인한 예기치 못한 공사비 증가에 대비하기 위한 수동적인 면에서의 전략도 있지만, 불확실한 요소의 분석을 통해 사전에 공사저해 요소를 제거하고자 하는 능동적인 면에서의 전략도 가지고 있다. 따라서 중장기적인 관점에서 예비비제도가 우리나라에 올바르게 정착되기 위해서는 공사종류별, 특성별 불확실한 요소로 인한 설계변경 사례에 대한 자료의 축적 및 면밀한 분석으로 적정한 예비비를 반영할 수 있어야 할 것이다. 이에 본 연구에서는 고속도로 공사라는 특정 공사에서 설계변경사례를 분석하여 공사비에 영향을 미치는 요소를 판별하고 회귀분석을 이용하여 예비비율을 산정하는 절차를 제시하고자 한다.

The concrete information technology (IT) has affected ways for supporting agricultural products. However, studies relating IT to agriculture in a broader sense have not been prevalent. The objective of this study is to improve agencies' effectiveness and performance in the use and application of IT through understanding the organizational fit and misfit. This research applied a multi-contingency view to Korean IT supporting agricultural promotion agencies and it evaluated the competitiveness of these agencies with reference to the correspondence of factors (Goal, Strategy, Environment, Knowledge Exchange, Task Design, and Information System) affecting their performance with organizational goals. The results reveal that organizations with good performance show better organizational fit with their organizational goal. This study contributes to the ways of efficient IT management in agricultural organizations in Korea.

In order to explore a relationship among KM context, KM effects, and sustainability of competitive advantage of organizations, a contingency model of KM, which is based on resource-based as well as knowledge-based theory, is developed from the information systems and strategic management literature. To put it concretely, our motivation for this paper was to answer the following questions: (1) What factors affect the degree to which an organization achieves KM effects? (2) Is there a positive relationship between KM effects and organizational performance achieved by linking KM to competitive advantage? A detailed exploratory analysis of survey responses from 79 Korean companies provides the following significant findings: (1) This study found support for the proposed research model. (2) The organization's degree of process and organizational outcomes of KM effects is determined by technical and social resources and its capabilities. Furthermore, the influence of technical and social resources of KM context on process and organizational outcomes of KM effects is controlled by different types of organizational perspectives on KM. (3) There is a relationship between process and organizational outcomes of KM effects and organizational performance enhanced by linking KM to competitive advantage.

Usability is one of the most important concepts regarding software quality. It can be interpreted as the goodness associated with using the software product. This paper distinguishes the goodness of an individual using experience and the goodness of a product for using. This paper proposes a software quality view model which classifies software quality views into two broad categories of end view and means view. End view includes long-term view and short-term view which is classified further into performer's view on software activity and third party's view on software activity. Means view includes intrinsic view and contingency view. The analysis of ISO 25000 Series SQuaRE demonstrates the necessity to decompose product quality model and quality in use model into five models corresponding to the software quality views respectively. The analysis on playability shows that the universal definition of usability may be an illusion. The results provide the theoretical basis to build a comprehensive and consistent body of knowledge regarding software quality, which is consisted with the set of quality models and the theories explaining the relationships among the elements of the models.
