Summary The management of infomation systems in many organizations is changing from data-based information processing to information as a strategic resource. This information system is termed information resouces management. This study focuses on the efficient management of the information resources. There are two major reasons for the change from information systems management to infomation resources management. One is the theory of information processing which places organizations in a resource management stage, the other is based on thechnological developments on the office automation and telecommuncations, and office automation. Now, these functions are could/should be managed interdependent on the views of infomation resources management. The organizational units requiring information resources are controlled by the centralized or decentralized management of the information systems function. In the selection of an alternative, we always consider the organizational situations. The operations and application development of information system functions also can be centralized or decentralized. According to the hardware location, processing control, and location of data, the alternative is selected. From the seystem development view point, system developmet personnel may be centralized and organized functionally or decentralized to report directly to user. And, a significant Management task is the allocation of scare information resources. Also, the two alternatives of allocation are a centralized authority method and a decentralized authority method. The issue of entralization or decentralization is not either or. There can be various combination of entralization or decentralization in accordance with orgnizational contingency. But, now the availability of low-cost personnel computer, development of telecornmunication. and motivation of end-users represent a significant shift to docentralization of information systems resource. The recruiting and retention of information systems personnel is a major management tasks. Thus, this study describes major job categories in information systems, the motivation of information systems personnel, and career path planning.

3次積率의 市場均衡模型의 分析

Markowitzs´ normative theory provides the basis for the positive theory of the valuation of risk asset developed by Sharpe and Lintner. The two parameter capital asset pricing model has been subject to numerous applications including performance measurement, tests of capital markets. Recently, several scholars have published empirical results which are inconsistent with the first two moments of the Sharpe-Lintner model. These studios suggest that the slope of the capital asset pricing model is lower and the intercept higher than predicted by the traditional theory. The first two moments of the return are sufficient information about the return distribution when it is a normal distribution or the utility function of investor is quadratic. But the distribution of the return is not normal and the utility function is not quadratic. So, more and higher moments of the return are necessary and because most of the information about any probability distribution is contained in its first three moments, the first three moments are take into consideration. And investors prefer the security with high positive skewness and avert the behavior which reduces the positive skewness. In these point of viewes, this paper extends the capital asset pricing model(market equilibrium model) to incorporate the effect of skewness on valuation. And market equilibrium model introduced in this paper shows that systematic skewness, rather than skewness, is relevant to market valuation.

Objectives: In order to investigate the relation between environmental pollution and its effect on human health in large-scale industrial complex regions, monitoring studies have been conducted since 2003. The main purpose of this Gangneung study is to produce background data which can be compared with several large-scale industrial complex regions such as Ulsan, Sihwa, Banwol, Gwangyang, Yeosu, Pohang and Cheongju Daesan industrial complexes. Methods: In this Gangneung study, 1,007 local residents were recruited and the framework of this study was designed to evaluate and monitor health effects associated with low-level but long-term exposure to environmental pollutants. A survey was performed based on personal questionnaires, medical check-ups, and allergy skin prick tests for twelve common allergens. The authors reviewed the prevalence rate of skin allergens in Gangneung compared with in large-scale industrial areas. The results are summarized as follows. Results: The diagnosis prevalence and medical treatment prevalence of asthma were lower than in industrial complex regions, but allergic rhinitis was higher. The allergy skin test prevalence was 26.0% and the most common allergens were dust mites (D. pteronysinus 16.7% and D. farinae 16.3%). Conclusions: The positive findings of the skin prick test were similar with large-scale industrial complex regions in Korea. Further study is required to find the cause of the regional differences in skin prick prevalence.

비산단지역 주민의 피부 알레르기 반응에 관한 연구

[연구배경] 국립환경과학원에서 지난 2003년부터 추진 중인 「산단지역 주민 건강영향 감시 사업」의 대상지역이 증가하면서 각 지역 특성에 따른 결과의 차이가 발생하여 정확한 해석 및 객관적인 비교를 위해 비산단지역으로서의 비교지역 조사에 대한 필요성이 제기되었다. 이에 지난 2006년부터 대규모 국가산단이 없는 지역 중 산단지역과 지리적, 인구학적, 환경조건이 비슷한 강릉을 비교지역으로 선정하여 격년으로 조사를 시작하였다. [연구목적] 본 연구의 목적은 대규모 국가산단이 없는 강릉지역 주민에 대한 피부 알레르기 반응 검사를 통하여 산단지역 주민의 피부 알레르기 반응 유병률과 비교할 수 있는 자료를 축적하는 데 있다. [연구방법] 조사기간은 2010년 4월~7월로 건강검진을 위해 지역 의료기관을 내원한 주민1,007명을 대상으로 총 12종의 알레르기 항원을 사용하여 피부단자검사를 시행하였다. 음성대조액은 항원희석에 사용하는 용매인 생리식염수를, 양성 대조액으로는 0.1% 히스타민용액을 사용하였다. 검사방법은 팔의 전박부에 시행하고 판독은 15~20분 후에 팽진 및 홍반의 크기를 측정하여, 음성 대조액에 반응을 보이지 않으면서 히스타민에 의한 반응과 동일하거나 그 이상인 경우를 양성으로 판정하였다. [연구결과] 총 12개 중 1개 이상의 항원에 양성반응을 보인 대상자는 262명(26.0%)으로, 이 중45.8%인 120명은 2개의 항원에, 24.8%인 65명은 3개 이상의 항원에 양성반응을 보였다. 항원별로는 주로 유럽형 집먼지진드기(16.7%)와 미국형 집먼지진드기(16.3%)였으며, 바퀴벌레와 초봄에 개화하는 나무 항원에서는 남녀간에 통계적으로 유의한 차이가 있었다. 2009년의 산단지역 조사결과와 비교한 결과, 울산이 22.5%, 광양만 24.9%, 포항 23.2%로 오히려 비교지역인 강릉이 약간 높았으나, 15개국 35개 지역 20∼44세 성인을 대상으로 9개 항원에 대한 유럽지역의 조사 결과 항원별로 17.1%∼54.8%의 양성반응률을 보여 지역 간 차이가 심한 것으로 나타났다. 한편, 조사에 사용한 항원이 주로 주거환경 및 자연에 존재하는 물질이라, 향후 주거를 포함한 생활환경 및 도시화 등과 같은 좀 더 정밀한 조사와 자료를 축적, 분석이 필요하다고 사료된다.
