As the budget size and complexity of 1T investment are growing, IT value measurement becomes more critical to the success of IT management In public organizations and private firms. It has been known that there are many factors such as IT costs, risks, qualify, and usage that should be taken Into consideration during the process of measuring IT value and making IT Investment decisions. However, little research has been done so far In order to analysis factors affecting the IT value and effectiveness. The purpose of this study Is to Investigate the impact of IT Project types and ownerships on IT value evaluation. The three research questions are as follows : (1) Does IT project type such as transactional, Informational, and infrastructure have any impact on 1T value measurement\ulcorner (2) Does the IT development ownership has any Impact on IT value\ulcorner (3) Does the IT operation ownership has any impact\ulcorner The empirical research was done at S-Electronics, world-wide known and the biggest manufacturing company in Korea, based on the method of structured interview. About 200 individual Information systems have been evaluated to calculate ROI measures, the dependent variable In this study. The results of statistical analysis show that two of three Independent variables, IT project types and IT development ownership, have statistically significant effects on IT value in terms of ROI measures.

The Comprehensive Rural Village Development Project, a resident-led bottom-up regional development project, began in 2004. This study investigated difficulties and problems in the operation process after the completion of the project, and future improvement plans, through in-depth interviews with the former and current chairman of the steering committee, steering committee members, and office managers, targeting three regions in Jeollanam-do, 15 years after the completion of the project. As a result of the survey and analysis, it was effective in improving the living environment and characteristics of each village and revitalizing the area. And while there were well-run facilities depending on the type of project, there were also many idle facilities. In the case of communal facilities, there was a high possibility of problems in operation and management when the scale of the new building was large. Conflicts occurred between villages in the process of independently operating the area after the completion of the project. Therefore, it is necessary to provide an S/W project program to prepare for after completion. Local governments need to utilize City and County Capacity Enhancement Projects to support regional leaders to participate in educational programs after completion and provide guidance and supervision for village operations.

Estimating time and cost is an important mission in the early phase of a construction project, especially in feasibility study. It provides a foundation for making decision whether or not the project is performed on schedule and within budget. Thus, reliability of this estimate plays a key role in measuring the success of a project. This study was carried out to investigate the time-cost relationship in building construction projects in Bangladesh. The mathematical equation used in this study is based on Bromilow's equation. The research data were collected from sixty-three completed building projects through questionnaire survey. Type of clients, type of projects, and tender methods are the project characteristics considered in this study. The results of analysis indicated that the Bromilow's time-cost (BTC) models developed for each project characteristic are appropriate due to quite high coefficient of determination and relatively small mean percent errors. Among them, the forecasted model for time and cost according to tender methods is the best fit model. It is concluded that the BTC model could be applied in building construction project to predict its time and cost in Bangladesh. Four different regression models were also developed in this study. The results of BTC model between some selected countries were compared to gain the comprehensive view.

It is well known that PMO (Project Management Office)s are effective for successful project performance. Since it takes a long time to develop PMO capability, many public organizations and companies that do not have internal PMOs are increasingly relying on outsourcing of PMO functions in order to introduce mature PMO capabilities in a short period of time. However, it is not verified yet whether outsourced PMO is more effective than internal PMO or not. The objective of this study is to verify the effectiveness of PMO outsourcing. There are many different definitions about PMO function, and even the same PMO function may have different effectiveness depending on the Industry. Thus, this study redefined the PMO functions and Project Performance based on the past studies, and conducted research by focusing on the ICT (Information and Communication Technology) industry. The ICT industry is an important industry economically and has been attracting global attention recently. This study is the first attempt to prove the effectiveness of outsourcing of PMO function in Korea. We found that PMO function outsourcing is effective for certain aspects of project performance, particularly technical support and infrastructure management. Overall, PMO outsourcing is usually more effective than internal PMO for improving project performance. The results of this study are expected to contribute to the development of PMO theories and practices.

Neurons make long-distance connections via their axons, and the accuracy and stability of these connections are crucial for brain function. Research using various animal models showed that the molecular and cellular mechanisms underlying the assembly and maintenance of neuronal circuitry are highly conserved in vertebrates. Therefore, to gain a deeper understanding of brain development and maintenance, an efficient vertebrate model is required, where the axons of a defined neuronal cell type can be genetically manipulated and selectively visualized in vivo. Placental mammals pose an experimental challenge, as time-consuming breeding of genetically modified animals is required due to their in utero development. Xenopus laevis, the most commonly used amphibian model, offers comparative advantages, since their embryos ex utero during which embryological manipulations can be performed. However, the tetraploidy of the X. laevis genome makes them not ideal for genetic studies. Here, we use Xenopus tropicalis, a diploid amphibian species, to visualize axonal pathfinding and degeneration of a single central nervous system neuronal cell type, the retinal ganglion cell (RGC). First, we show that RGC axons follow the developmental trajectory previously described in X. laevis with a slightly different timeline. Second, we demonstrate that co-electroporation of DNA and/or oligonucleotides enables the visualization of gene function-altered RGC axons in an intact brain. Finally, using this method, we show that the axon-autonomous, Sarm1-dependent axon destruction program operates in X. tropicalis. Taken together, the present study demonstrates that the visual system of X. tropicalis is a highly efficient model to identify new molecular mechanisms underlying axon guidance and survival.

Nowadays, there has been extreme competition due to market reduction in the domestic construction industry. In this situation, Korean construction companies are focused in the area of planning development housing project, which should maximize profit for a project. The most important step in this project is the business planning stage which judge whether it could come true or not. Each company has its own planning process model, but there hasn't been any standard model for the business planning process. To solve this problem in Korean construction companies, this study identifies the existing business planning process in the domestic construction companies finds out its problems, and suggests solutions for thorn. And Finally a business planning process model is proposed for success in development housing projects.

The main purpose of this research project is to monitor the present state of agricultural environment and to develope the countermeasures for the protection of the environment from the pollution by animal wastes. The results of this research were described largely 3 parts, 1) Monitoring of present state of environmental pollution by animal wastes, 2) Monitoring of animal wastes treatment technology, 3) Strategies for the protection of environmental pollution from animal wastes in future. The current most important problems from animal wastes are water pollution and air pollution commonly regardless of domestic or foreign country. Especially, intensive livestocks breeding pattern in restricted area is actually a real reason of eutrophication, soil acidification, ground water contamination, irrigation water pollution. As a result from this research project, authors recommend the 3 type of strategies for the protection of environmental pollution by animal wastes, 1 . Development of non-discharge type of wastes treatment technology 2. Manufacturing local structure for animal waste recycling system 3. Development of new international environmental program for transfer bioresource and soil environment prevention.

One of the problems associated with the current system of land development projects implemented by the public sector in Korea is that various service facilities are not ready in time for the occupation of residential dwelling. A major cause of the problem is the lack of financial arrangements which would smooth the cash-flow of the suppliers of the facilities during the project period. In this paper we present two schemes which will contribute to the optimal provision of service facilities by easing the financial constraint facing the land developers and suppliers of the facilities. The first scheme involves channeling a fraction of profits from a land development project and of the proceeds of mandatory sales of Type II National Housing Bonds as a loan to the suppliers of the service facilities. The second scheme considers the participation of the private sector in the project as a member of a consortium comprising the Korea Land development Corporation, the National Housing Fund, and private developers. It is proved that each scheme is superior to the current system. as well as entailing a very small cost.

This study aimed to categorize mountain villages according to business expense investments and investigate residents' supplementation demands and differences between expected effects by the categories. For the study, 35 villages where are completely developed on and after 2007 were selected to consider fairness among local governments. Each village leader(the head of the village or the chairperson of the management committee) was conducted a survey from 2012 May to August and one copy of survey was eliminated from the study. The study is summarized into four results. First, the types of mountain villages were categorized as a type of mountain village practice(18), a type of life environment improvement(8) and a type of forestry income(8) according by the itemized reports of the business expense investments. Second, the result of F-test(One Way ANOVA) for the average analysis by types showed that 3 out of 6 demands for the operation were significant differences and a supplementation necessity of the program was identified significant differences in p<0.01 level. The necessity of forestry resources use and sprawling development prevention are also showed significant differences among types in p<0.05 level. Third, F-test results from 7 questions of desired effects through mountain village creation project revealed that promotion and market security of forestry products and local patriotism instillation through a personal exchange are significant differences between types in p<0.05 level. Forth, the results of duplication benefits(the mountain village development projects and the village support programs with other departments) on the residents' development expectation found that when a village received a large number of projects, residents' expected effects were higher than other village residents where received relatively a small number of projects. However, the expected effects from the increasing quantities of projects were decreased.
