This study is to suggest some improvement directions of the criteria for the management evaluation in order to contribute to the achievement of lasting value of the continuous development and publicity in regard to the public library means-efficiency. To this end, This study analyzed the means-efficiency evaluation criteria via theoretical review on business analysis of private enterprise and the analysis framework based on it. The improvement of evaluation criteria in regard to efficiency for the continuous development of public library are as follows. 1) Regardless of domestic and foreign, an efficiency index in the performance evaluation index of public library is absolutely insufficient. The sufficient indexes measuring efficiency which is appropriate for the concept of performance should be developed. 2) A flow data representing input and performance in certain time period is insufficient. Therefore, evaluation index consisted of flow data should be more developed. 3) Long term stock data is excluded in the term cost as it is the cost used for the long term such as fixed assets. However, it is useful as input data, which is realized through the perfect accounting.

지난 수년간, IT 비용의 지속적인 증가에 따른 IT 투자 의사결정 및 평가를 위한 성과 분석은 최근 가장 주요한 이슈가 되고 있다. IT 투자와 성과간의 상관 관계를 규명하기 위한 수많은 노력에도 불구하고 IT 투자 성과 측정의 어려움과 이에 영향을 미치는 요소들의 복합성으로 인하여 낮은 IT 투자 성과의 원인을 제시하는 것은 여전히 쉽지 않은 문제이다. 본 연구는 실제 IT 투자 규모와 IT 투자 성과간의 상관관계를 분석하고, 이에 조직, IS프로젝트, 사용자 요인들이 어떻게 영향을 미치는지 나타내고자 하였다. 2개 제조업체의 총 44개의 단위시스템들에 대하여, IT 투자 비용은 형태별로, IT 투자 성과는 정성적, 정량적인 효과를 정보, 시스템, 사용자, 조직효과 관점에서 측정하고 있다. 또한, 각 시스템을 구축하였던 업무 담당자들, 사용자들에 대한 인터뷰 및 설문을 통하여 조직, IS프로젝트, 사용자 요인을 측정하고 있다. 본 연구는 효과적인 IT 투자 성과를 얻기 위해서는, 절대적인 IT 투자 규모도 중요하지만 구체적인 정보전략계획의 수립, 경영진의 지원, 사용자의 적극적 참여와 같은 IT 투자 실행의 중요성을 제시하고 있다. 이들 결과를 바탕으로 IT 투자를 고려하고 있는 기업들에게 효과적인 투자 방안을 제시할 수 있을 것이다.

The purpose of this paper is to analyze cost-effectiveness of a train simulator. The cost-effectiveness of training program is assessed by multiplying transfer effectiveness ratio (TER) by training cost ratio (TCR). If their product is less than one, the program is not cost effective. Even if a program is not cost effective, however, safety considerations may be important to consider. Findings indicated that each type of train simulators might be used with each type of training programs appropriately for improving cost-effectiveness of a train simulator.

This paper aims to study on the relationship of u-Security service, usefulness and citizen satisfaction. Independence variable is u-Security service, a mediation parameter is usefulness, and dependent variable is citizen satisfaction. Using SPSS 18.0, a series of factor analysis, reliability analysis, multiple regression analysis and path analysis have been performed. The conclusion is as following. First, u-Security service affects usefulness. That is, as publicity safety, system quality, service quality increase, usefulness increases. Second, u-Security service affects citizen satisfaction. That is, as publicity safety, system quality, service quality increase, citizen satisfaction increases. Third, usefulness affects citizen satisfaction. That is, as economic usefulness and security usefulness increase, citizen satisfaction increases. Last, u-Security service has direct and indirect effect in usefulness and citizen satisfaction. That is, usefulness is an important variable that mediates u-Security service and citizen satisfaction.

A coherence theory is adequate as a theory of justification only when justification as conceived by the theory is truth-conducive. But it is not clear how coherentist justification is truth-conducive. This is the alleged truth-conduciveness problem of coherentism. In my 2017 paper, I argued that a certain version of the coherence theory, namely a Sellarsian coherence theory combined with the deflationary conception of truth, can cope with this problem. Against this claim, Kiyong Suk argues in his recent paper that my proposed solution fails on the grounds that there is no practical way of distinguishing between intersubjective justification and objective justification. The purpose of this paper is to clarify my view by way of explaining why Suk's criticism is not correct. In particular, I argue that his criticism is based on a wrong assumption, namely that for one to be objectively justified in believing something, one's justification must be qualitatively transformed into the status of having objective justification from the status of having intersubjective justification.

Relative importance and complexity of recent software is getting increased because the software is needed to provide considerable amount of functions and high performance. Therefore, developing reliable software is importantly issued. In order to develop reliable software, it is necessary to manage software reliability at the early phases, but most reliability estimation models are used at system or operational test phases. In order to develop highly reliable software, it is necessary to manage software reliability at the early test phases based on characteristic of the phases that is developers and testers are not separated and developers perform test and debug activities together. Therefore, a new reliability estimation model considering test and debug time together is necessarily needed. In this paper, we propose a new reliability estimation model to manage reliability of individual units from the early test phases and in order to show how to fit the model to actual data and usefulness, we collected industrial data and used it for the experiment.

This paper is an attempt to account for the uncertainty of the residual strength in the reliability analysis of structural systems. For this purpose the stochastic finite element method(SFEM) is linked to the system reliability analysis procedure. The stochastic finite element is known to be able to a more explicitly consider the effect of uncerainties of material and geometric variables on those of load effects in structural analysis procedure. The method has been applied to system as well as component reliability analysis of a plane structure. Comparison of the results by the present approach is made with the method in which the residual strength of failed component is treated as deterministic variable. Several case studies have been carried to show the effect of uncertainty in residual strength of a member after failure. Is has been conformed that reidual strength very much affect the system reliability level. It can be, hence, concluded that the uncertainties in the post-ultirnate behaviour may have to be taken into account in the system reliability analysis for a better a ssessment of the system reliability especially for a structure of which member behaviour is modelled as asemi-brittle model. And then the stochastic finite element method can efficiently evaluate the system reliability.

We investigate long-run relationships between industry relatedness, operating performance, and stock performance after equity carve-outs(ECO). For homo-industry ECOs, 12-month CAR of subsidiary firms is 26.52% and significantly positive at the 5% level and BHAR is 22.19%. For hetero-industry ECOs, subsidiary 12-month CAR and BHAR are 35.14% and 39.64%, respectively, which are significant at the 1% level. On the other hand, long-run performance of parent firms is insignificant for any sub-sample. Excess operating performance of subsidiaries is significantly positive at the first year and insignificant thereafter. The lower the offering ratio is and the better the operating performance is, the better the subsidiary stock performance is. Unlike IPOs and SEOs, shareholders of subsidiaries benefit from ECOs and parent stocks do not underperform. Hetero-industry ECOs improving corporate focus are more effective restructurings than homo-industry ECOs.

This study is to discuss on intrinsic justification of 'citizenship' and 'spaces of citizenship' to inquiry possibility of citizenship education through geography subject. According to Peters' educational view as forms of knowledge and initiation, citizenship was intrinsically justified through examination of forms of geographical knowledge. The analysis of paradigms in geography shows that 'the human' and 'the social' are generally combined in 'space'-centered language and ideologies through post-positivism. That is, it refuses the concept of physical space which is value neutral, and seeks turn to spaces of citizenship which is value-intrinsic through social space theory. Given that changes in the forms of geographical knowledge lead changes in content knowledge of geography subject, citizenship is to be justified intrinsically. Thus, citizenship as content knowledge of geography subject is to be justified not extrinsically through acceptance of social studies' educational aim in itself but intrinsically through forms of geographical knowledge. And geographical education as initiation into value and belief of citizenship based on these spaces of citizenship is not about making students have arrived at a destination, but about them travel with a different view.

The purpose of this study was to explore high school teachers' subjective perception on performance-based pay system(PBPS) for teachers using Q-methodology. This study found three types of high school teachers' subjective perception on the system. Type I is named 'the type of negative perception.' The subjects of type I emphasize the PBPS is not appropriate system for motivating teachers' educational behaviors. Type II is named 'the type of neutral perception.' The subjects of type II emphasize the PBPS is a fair job evaluation, strengthening cooperative atmosphere of educational community but the system is not an usefulness for causing educational behavior etc. Type III is named 'the type of acceptive perception.' The subjects of type III emphasize the PBPS is a good policy to reward for the work most people avoid getting into and improve culture of teaching job etc.
