In disputes involving contracts for work, most issues boil down a single, most crucial, underlying question: whether the agreed work was completed. The same applies to software development services, which are usually usually provided under contracts for work. In disputes arising from software development contracts, appraisal is commonly used to determine the completeness of the software in question. However, it is often difficult to ensure the objectivity of the appraisal. This study examines past cases involving the determination of software completeness to identify the method used in each case. Then, based on the findings, this study identifies issues requiring improvements to ensure objective determination of completeness.

Regarding project management, many organizations have developed and distributed general project management knowledge systems, and application fields use the knowledge systems to apply the process suitable for characteristics of a project. This study suggests project management process models to apply to system integration projects. This system integration project management process model is composed of six top processes of initiation, preparation for contract, planning, implementation management, coordination and control, and termination and transfer. The five processes are re-divided into 25 bottom processes. These processes are expressed as input, control, output, and mechanism by using the IDEF0 model. For this model development, it has chosen the items which constituted a process through a questionnaire of experts.

The purpose of this study is to figure out the movements of policy actors in the policy process of the establishment of a local cultural foundation in B-gu(district), A-si (city), then to explore the way to contract out of the management of public libraries to the cultural foundation in the policy process. Data for the study were collected from various sources from newspapers and assembly minutes to blogs and SNS messages of the policy actors, then analysed based on Advocacy Coalition Framework (ACF). The results showed that 'agreement of contract-out' coalition only accepted public interest of the public libraries between the public interest and specialty of librarianship which were insisted by 'disagreement of contract-out' coalition's policy beliefs. The comparison between this case and a similar policy case showed that the specialty of librarianship as a core belief is effective in changing the beliefs of other coalition. Eventually, it is required to differentiate and to specialize library services among public services in a local area in order to keep the direct management of public libraries by the local government, and this means that everyday library services influence the decision making of library policies in the local area.

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 is to figure out the current condition of local governments (Si or Gun) to implement rural development policy in the face of the central government's drive for increasing devolution. Since late 1990s or early 2000s when scope of rural policy began to expand quantitatively, there has been considerable increase in rural residents' participation into community projects as a whole. Nevertheless, there exists regional differentiation in local governments' efforts to systematically support rural development projects (CRDP: Comprehensive Rural Development Programme) and community activities by setting up intermediary organizations or hiring rural development professionals in a public office. According to this survey on local government officials, regions that have made such efforts to support rural policy at a local level, show more advanced level of institutional capacity than other regions in local decision making process for CRDP, role of strategic rural developmental plans, vitality of community actors, etc. In the era of increasing devolution, these differences can be expected to result in diverging performances of each area in regionalized rural policy. The central government needs to introduce EU's LEADER-type rural development programmes to support community acitivities by various local actors and at the same time promote local governance building for rural policy, adopting institutional rewarding system such as rural planning contract.

In general, hot metal castings contract and molds expand during the cooling step of a casting process. Therefore, it is important to consider both the casting and mold at the same time in a casting process analysis. For a more accurate analysis that includes the contact characteristics, matching each node of the casting and mold in the contact area is recommended. However, it is very difficult to match the nodes of the casting and the mold when generating elements due to the geometric problem of CAD model data. The present study proposes a mesh generation technique that considers mechanical contact between the casting and the mold in a casting analysis (finite element analysis). The technique focuses on the fact that the mold surrounds the casting. After generating the 3D elements for the casting, the surface elements of the casting in contact with the mold are projected inside the mold to create contact elements that coincide with the contact surface of the casting. It was confirmed that high-quality contact element information and a 3D element net can be automatically generated by the method proposed in this study.

Verifying the similarity of environmental characteristics between an artificial impact site and a preserved or reference site is necessary to quantitatively and qualitatively evaluate the environmental impact of mining activity. Although an impact site (BIS station) and a preserved site (called KOMO station) that have been selected in the Korea manganese nodule contract area may share similar environmental characteristics, similarities in terms of the water column environment between both sites has not been investigated. In this study, we compared the chemical properties of the water columns and sinking particle fluxes between BIS and KOMO stations through two observations (August 2011 and September 2012). Additionally, we observed particle fluxes at the KOMO station for five years (July 2003~July 2008) to understand long-term natural variability. Vertical distributions of water column properties such as dissolved oxygen, inorganic nutrients (N, P, Si), total organic carbon below surface layer (within the depth range of 200 m) were not considerably different between the two sites. Especially, values of water column parameters in the abyssopelagic zone from 4000 m to bottom layer (~5000 m) were very similar between the BIS and KOMO sites. Sinking particle fluxes from the two sites also showed similar seasonality. However, natural variation of particle flux at the KOMO site varied from 3.5 to $129.9mg\;m^{-2}day^{-1}$, with a distinct temporal variation originating from ENSO events (almost forty times higher than a minimum value). These results could provide valuable information to more exactly evaluate the environmental impact of mining activity on water columns.
