As the scale of construction work is enlarged, complicated and diversified, much construction information from the large number of construction sites is generated and reported to the head office. To control much information generated in construction sites simultaneously, the necessity of supporting system which could extract necessary information is increased. However, comparing with those of large companies, medium-sized companies's organization of head office and management system are weak. So it's difficult to manage multi-projects. Among these site managements, resource management is an important management area. But, resource planning is based on experience and judgement and has not associated with schedule information. So when schedule is changed, the plan must be amended manually. This study investigates material-planning model for multi-project management which is connected with daily report system and scheduling software.

This study examines whether the executive turnover and the executive resignation during the term of office affect the performance of Korean state-owned enterprises. The executive turnover in the paper means the comprehensive change of the executives which includes the change after the term of office, the change after consecutive terms and the change during the term of office. The 'resignation' was named for the executive change during the term of office to distinguish from the executive turnover. The study scope of the paper is restrained to the comprehensive executive change itself irrespective of the term of office and the resignation during the term of office. Therefore the natural change of the executive after the term of office or the change after consecutive terms is not included in the study. Spontaneous resignation and forced resignation are not distinguished in the paper as the distinction between the two is not easy. The paper uses both the margin of return on asset and the margin of return on asset adjusted by industry as proxies of the performance of state-owned enterprises. The business nature of state-owned enterprise is considered in the study, the public nature not in it. The paper uses the five year (2004 to 2008) samples of 24 firms designated as public enterprises by Korean government. The analysis results are as follows. First, 45.1% of CEOs were changed a year during the sample period on the average. The average tenure period of CEOs was 2 years and 3 months and 49.9% among the changed CEOs resigned during the term of office. 41.6% of internal auditors were changed a year on the average. The average tenure period of internal auditors was 2 years and 2 months and 51.0% among the changed internal auditors resigned during the term of office. In case of outside directors, on average, 38.2% were changed a year. The average tenure period was 2 years and 7 months and 25.4% among the changed internal directors resigned during the term of office. These statistics show that numerous CEOs resigned before the finish of the three year term in office. Also, considering the tenure of an internal auditor and an outside director which diminished from 3 years to 2 years by an Act on the Management of Public Institutions (applied to the executives appointed since April 2007), it seems most internal auditors resigned during the term of office but most outside directors resigned after the end of the term. Secondly, There was no evidence that the executives were changed during the term of office because of the bad performance of prior year. On the other hand, contrary to the normal expectation, the performance of prior year of the state-owned enterprise where an outside director resigned during the term of office was significantly higher than that of other state-owned enterprises. It means that the clauses in related laws on the executive dismissal on grounds of bad performance did not work normally. Instead it can be said that the executive change was made by non-economic reasons such as a political motivation. Thirdly, the results from a fixed effect model show there were evidences that performance turned negatively when CEOs or outside directors resigned during the term of office. CEO's resignation during the term of office gave a significantly negative effect on the margin of return on asset. Outside director's resignation during the term of office lowered significantly the margin of return on asset adjusted by industry. These results suggest that the executive's change in Korean state-owned enterprises was not made by objective or economic standards such as management performance assessment and the negative effect on performance of the enterprises was had by the unfaithful obeyance of the legal executive term.

The concerns for higher returns among investors in Korea are increasing as local interest rates lag behind the global market. The aim of this study was to provide a basis for estimating the precise return on investment to private investors and stakeholders of office buildings by identifying the optimal scale estimation of office building space, derived from managerial expenses. The literature on the economies theories of scales were reviewed, and the average administrative costs on an appropriate scale were assessed by cross-analysis and regression analysis using the U-shaped quadratic and cubic function. The findings suggest that the average office building managerial costs are approximately 6-11% according to the region, 10-13% according to the grade, and 8-9% according to size. Corporate-owned buildings represent the highest in terms of the average managerial costs, and there is an approximately 11.5% difference when it comes to outsourcing. In addition, the elapsed year showed that approximately 5.3 years to meet the lowest U-shaped curve of the average managerial cost. The 'Total floor area' variable shows a ${\bigcap}$-shape as it continue to increase to 72,000-Pyung then decrease gradually. This study presents the fundamental proposition of efficient and practical management of cost, lease and operation for real estate management firms by utilizing LCC.

Though digital imaging devices such as smart phones, digital cameras and office scanners have improved significantly over the past years, they are seldom used for industrial application. This may be attributable to high level of quality and performance requirement for industrial application, but there lacks a test or an objective evaluation whether the upgraded performance of entry-level device is sufficiently enough to replace existing industrial equipments or not. If there exists an industrial application area where the applicability of entry-level equipment is proved by some objective tests, then companies will be able to reduce investment on expensive industrial equipment. In this study, applicability of entry-level digital devices for color difference discrimination of PVC (Polyvinyl chloride) color sheet is tested. By testing smart phone, digital camera, and office scanner for color difference discrimination, authors have found that office scanner shows consistent result with less measurement error. Additional experiment on comparing office scanner with industrial spectrophotometer has confirmed that there exists high correlation between the two devices' results. Based on this result, office scanner may be applicable to discriminate the color difference of PVC sheet instead of expensive industrial spectrophotometer if proper management criteria are established.

The foremost priority for establishing record management of public institutions is strengthening the function and role of the records centers in the institutions and creating the foundation of the organization and personnel for demonstrating professionalism of archivists. However, concept of current records center is not clear and there is no substance of the organization. It also says that once a records manager is deployed, a records center is founded since appointment criteria for archivists is prone to be interpreted subjectively by the institutions. Therefore, it's time for more concrete improvements to resolve these issues. This research analyses some problems found in the system of records centers in the main office and district offices of education focusing on the environment of them. The problems are centers without substance in district offices of education because of the organization structure that all authority has been assembled in the main office, and the reality of records managers who have fallen into records discarders, etc. To solve these problems, this paper proposes changing the appointment criteria for archivists, operating an integrated records center reflecting the intensive working system, and legislating special act on record management of educational institutions.

Opening special dental office like prosthetic, orthodontics and implant is getting popular from the specialization and ramification on dental service. It shows how changes onpeople's point of view on dental offices as a business and high interesting on aesthetic. The child dental office also specialized from 1990s. It had been divided by not sort of sickness but ages of children. Thus it should support not just basic functions what other dentist of vice does but also comfortable environment to guide children patients' behavior who get afraid easily. However the interior of existing the child dental office was more focused on visual decoration but consideration of space. Thus the space is very superficial and plain, so there is limitation to give suitable environment to children patients. Therefore, from this study, I will research what is the proper space to control children patients' behavior based on well balance of space and decoration designs. Also from the research, I will explain fundamental design ideas on the child dental office space.

Background: Clinical indicators are objective measures of process or outcome of patient care in quantitative terms. This study aims to review the medical records of patients who 'return to operating room during the same admission', which is one of the critical clinical outcomes, and describe the result by unplanned reoperation rate. Methods: Computerized patient registry was used for selecting subject conditions. For medical records retrieved, two nurse evaluators identified the presence of explicit reoperation planning in medical records. Results: Overall reoperation rate was 2.8% and unplanned reoperation rate 1.3%. The main category of reoperation cause was the postoperative bleeding. Duration of stay from previous operation to reoperation of the unplanned group, 12.7 days, was shorter than that of the planned(p< .05). The differences did not reach statistical significance in age, sex and length of stay. Conclusion: Results suggested that unplanned reoperation rate was lower than 'threshold' level other institutions had established. However, this result could become comparable only after management of medical records would be improved and risk adjusted.

The propose of this study is to suggest objective data to be utilized for a plan and the improvement of open space through the analysis of people's behaviour and satisfaction after the introduction of an opened-fence around offices followed by a plan for wall-afforestation of public institution's. The sites examined are four offices; two of them have opened-walls and the others have traditional enclosure. Analysis of frequency is conducted to understand the actual use according to people's individual peculiarities. Pearson's correlation analysis, t-test, multiple regression analysis are carried out to find out relations of fluents. In the end, the satisfaction is high in public institution satisfaction, entrance, space perception. stability, Landscaped office with opened-fence rather than fence, and the increase in usage of fluent of public institution satisfaction, entrance, space perception. stability, confusion brings about rising of use-satisfaction. Satisfaction with the exterior of building is the most important variable that influences the whole urban open space. Furthermore the influences of the approach and stability having connection with open or not-open fence is major variable affecting satisfaction of use of open space. Whether open or not is important factor on satisfaction of open space of office building. Through this study, we can find that opened fence determines use satisfaction of resting space of outdoor-office. So factors affecting satisfaction must be regarded as important requisite on planning, design, development and management in plan for afforestation of fence at public institution.
