This study investigates the relationship between some control factors of systems analysis and information systems effectiveness. For this purpose, a research model is set up that consists of three independent variables (duration of systems analysis, user involvement, and control organization/mechanism) and a dependent variable (user satisfaction). Data were gathered from thirty-two industry firms in Korea. The results of data analysis indicate that only user involvement is significantly related to the dependent variable. Among independent variables, the existence of the sign-off procedure and auditing organization is associated with the relative duration of systems analysis. Discussions of the results are presented, followed by the suggestions for future research.

Despite the large and ongoing investments in information systems and technologies, many organizations still suffer from the lack of integration and interoperability of multiple information systems, In order to deal with these enduring problems, a number of government organizations and corporate firms in the United States have developed and maintained IT architectures through enterprise architecture planning. An IT architecture is a decision-making framework for IT planners and developers, establishing guidelines for the individual IT resource owners and users. It provides guidance to those involved in building and maintaining IT systems and infrastructure. Enterprise architecture planning represents a new paradigm of information systems planning in that it addresses the long-term view of the enterprise organization from top-level principles to detailed technology architectures. This paper explores a couple of cases in the successful implementation of IT architectures in both public and private sectors, and proposes a step-by-step methodology for building an effective IT architecture.

한국인의 초과 방사선 암 위험도 평가에 근거한 국내원전의 안전목표치 설정 방법론

By using the Korean demographic data and the modified relative risk projection model given in the Committee on the Biological Effect of Ionizing Radiation (BEIR) report-V under the U.S. National Academy of Science, the radiogenic excess risk in Korean population has been evaluated. On the basis of this risk, a safety goal for the safe operation of domestic nuclear power plants has been further derived in terms of personal dose. The baseline risk of death due to all causes in Korea and the trivial risk level, which the society considers safe, were estimated to be $5.2{\times}10^{-3}$ and $5.2{\times}10^{-6}$, respectively. The radiogenic excess cancer risk in Korea has been estimated to be $5.2{\times}10^{-3}$ for tie case of acute exposure to 0.1 Gy and $3.7{\times}10^{-3}$ for the case of chronic lifetime exposure to 1.0 mGy/y. On the basis of these risks estimate, the resulting safety goal for one year opeation of a reactor was 0.05 mSv, which is quite identical with the ALARA guideline prescribed by the USNRC in the Appendix I, 10CFR50.

방사선량의 측정, 평가에서 선량당량(dose equivalent)과 등가선량(equivalent dose)의 정의 및 차이

국제방사선어위윈회(ICRP)는 최근의 권고 60(1990)에서 이전의 권고 26(1976)에는 없었던 새로운 용어들을 도입하였다. 이중에서도 동 위원회는 지금까지 사용되어왔던 국제방사선단위 및 측정위원회(ICRU) 개념의 "선량당량(dose equivalent)"을 대체하는 용어로 "등가선량(equivalent dose)"을 새로 정의하여 방사선방어 프로그램에의 적용을 권고하고 있다. 그러나 한편 동 위원회는 선량 당량이라는 용어도 여전히 채택하고 있기 때문에 경우에 따라 두 양의 사용시 불필요한 혼동을 불러 일으킬 수가 있다. 따라서 본 해설문에서는 방사선 방어, 관리 및 측정분야 종사자들의 이해를 돕기 위하여 두 양의 정의와 사용상의 차이점에 대하여 정리하였다. It its recent recommendation No. 60(1990), ICRP has newly introduced several terminology which had not existed in its prior recommendation No. 26(1977). Of those, a newly defined quantity “Equivalent Dose” replacing the "Dose Equivalent" of the ICRU concept has been recommended to be adopted in the radiation protection programme. However, since the committee still uses the “Dose Equivalent” and “Equivalent Dose” in its several publications, it is likely to provoke unnecessary confusions and misuses in applying these two quantities. In this paper were described the definition and difference between these two quantities to help in understanding of these two quantities among the person involved in the radiation protection activities.

Plasma electrolytic oxidation (PEO) treatment was performed on cast Mg-6 wt%Al alloy solution-treated at 693K for 16h and aged at 498K. The surface roughness, thickness, micro-hardness, wear and corrosion properties of coatings on solution-treated and aged Mg-6 wt%Al alloy were investigated. The coatings on aged Mg-6 wt%Al alloy had thinner layer and lower micro-hardness and wear resistance than the solution-treated Mg-6 wt%Al alloy. As the aging time increased, the thickness of coatings decreased while the surface roughness was almost no changed. In addition, the micro-hardness and wear property of coatings decreased with increasing the aging time unlike the uncoated Mg-6 wt%Al alloy showing the peak micro-hardness and the best wear property after aging for 16 h. However, the coatings on Mg-6 wt%Al alloy peak-aged for 16h revealed the best corrosion resistance in 3.5% NaCl solution, which was explained based on the microstructural characteristics.

기업간 관계요인이 협업적 IT 활동과 기업성과에 미치는 영향

With the diffusion of the Internet, firms try to electronically collaborate with their partners in order to cut costs and gain profits. This electronic partnership, called ‘Collaborative IT' is quite popular between large purchase enterprises and small­to­medium sized sub­contractors. This study investigates such relations. This study proposes three groups of research variables - interorganizational relationship, collaborative IT activity, and firm performance. The interorganizational relationship consists of trust, commitment, and asymmetry of commitment. Collaborative IT activity is composed of information sharing and workflow integration. The ultimate dependent variable is firm performance. It is hypothesized that the relationship factors influence the level of collaborative IT activity, while the latter in turn affects the firm performance. The relationship factors may also directly affect the dependent variable. In addition, collaborative IT motive, as a moderating variable, may influence the causal relationship. By means of survey, one hundred and eighty­two responses were obtained. Most sample companies are small­sized, in the manufacturing sector. The analysis of data reveals that both trust and commitment positively affects the level of collaborative IT activity, while asymmetry of commitment has negative effects. The workflow integration is significantly related with firm performance. Information sharing, however, has no significant effects. Furthermore, asymmetry of commitment shows reverse relationship with firm performance. Collaborative IT motive works as a moderating variable between information sharing and firm performance. Finally, workflow integration is believed to mediate between relationship factors and firm performance.
