For the successful operation of the current organization, the importance of the information system is further increasing, and audit for the information system construction is also spreading according to the mandatory of information system audit. However our country's information system audit still does not deal with various risks and the improvement plan of it is desperately needed since bad practices are often happened while performing audit for the various information system projects. Therefore, this paper proposed improved review items for the quality improvement of information system construction by analysing data of information system audit projects and risk occurrence projects that are performed by the domestic large SI company during four years. In addition, this paper verified the effectiveness of the improved review items proposed in this paper by applying them to actual information system project examples.

The purpose of this study was to suggest development strategies of a village of Hwaseong-si where several programs using it's traditional items have been operated since 2003 according to the policy of Rural Traditional Thema Village Development implemented by Rural Development Administration(RDA). The village is located in Yodang-ri, Yanggam-myun, hwaseong-si in Gyounggi province. The village is called as 'Eunheng Namu Maeul' which means 'ginkgo tree village' since the tree is almost 350 years old and beautifully huge. Including this big tree there are much more traditional items such as organic dairy farming, hand-made cheese, legends and traditional plays. Using this items and government subsidies, the village has managed various tour programs and other income increasing projects. This study analyzed the strengths, weaknesses, opportunities and threats of the current situation of the village with the related materials and data to find out development strategies for the village-based programs and projects. This study recommended the followings as a major result of this study. The huge ginkgo tree at the village could be a better traditional attractive item when paths and wood of ginkgo trees will be built up especially utilizing the original huge one around the village. Like this, the item of hand made cheese could be a much more valuable traditional item when there will be an advanced facility for the people's working together. The social actives of the village have been weakened because of few young dwellers living there, therefore there needs a special subsidizing project for the village to hire a young manager having some social skills and knowledges. The situation being urbanized in front of the village needs precisely checking and implementing the Hwaseong-si's urbanization policy so that the urbanization could be harmonized with the maintenance and development of the traditional items of the village.

Due to the global business environments and severe competitions, SMEs have carried out IS projects for their competitive advantages. However, numerous organizations have faced with difficulties in the IS project management such as large amounts of IT expenses and uncertainties in project implementations. Thus, this study is intended to discover critical risk factors in the IS project management. To achieve this research goal, we have mailed questionnaires to SMEs and SI companies that experienced IS project failures and 63 usual data were collected. The result of analysis with step wise regression showed that 6 factors are related with IS project failures. The study contributes to the literature in two ways. First, this paper empirically identifies IS risk factors for SME manufactures. Second, this research result can be utilized as a checklist for the successful IS implementations. Limitations and future research topics are also discussed.

Data Envelopment Analysis(DEA), a non-parametric productivity analysis tool, has become an accepted approach for assessing efficiency in a wide range of fields. Despite of its extensive applications, some features of DEA remain bothersome. DEA offers no guidelines to where relatively inefficient DMU(Decision Making Unit) improve since a reference set of an inefficient DMU consists of several efficient DMUs and it doesn't provide a stepwise path for improving the efficiency of each inefficient DMU considering the difference of efficiency. We aim to show that DEA can be used to evaluate the efficiency of System Integration Projects and suggest the methodology which overcomes the limitation of DEA through hybrid analysis utilizing DEA along with machine learning.

The building integrated photovoltaic system (BIPV) attracts attention with regard to the future of the photovoltaic (PV) industry. It is because one of the promising national and civilian projects in the country. Since land area is limited, there is considerable interest in BIPV systems with a variety of angles and shapes of PV panels. It is therefore expected to be one of the major fields for the PV industry in the future. Since the irradiation is different from each installation angle, the output can be predicted by the angles. This is critical for a PV system to be operated at maximum power and use an efficient design. The development characteristics of tilted angles based on data results obtained via long-term monitoring need to be analyzed. The ratio of the theoretically available and actual outputs is compared with the installation angles of each PV module to provide a suitable PV system for the user.

As rural development projects, mostly carried out in a top-down development method in the past came to take a bottom-up development method in earnest, entering the 2000s, resident participation became an essential element of a rural community design project, to the extent that it can influence the success or failure of a rural community design project. It is taken for granted that rural residents independently participate in community design projects, but as they are accustomed to various subsidy projects carried out by the government and become increasingly aging, it is not easy to induce their spontaneous participation in farming areas with such problems. Especially, to prevent the distrust between administrative agencies and residents from serving as an obstacle in the residents' spontaneous participation, it is necessary to construct horizontal governance among the village residents, administrative agencies and the group of experts supporting for the project. This study attempted to verify the mediating effect of governance in the relationship between resident participation and the performance of the rural community design project based on this problem recognition, and for this purpose, the results of a survey with residents in Utturu Village, Hangyeong-myeon, Jeju-si, which was completed by carrying out a comprehensive rural development project, the typical bottom-up community design project was used for an empirical analysis. The results of the study can provide implications for setting directions, establishing strategies and constructing governance of rural community design projects in the future, and especially, it can be said that this study has academic significance in that governance is recognized as an important variable related to the project performance.
