In this paper, we suggest the roles of IPP (Industry Professional Practice) professor that are necessary for efficient and systematic operation and management of IPP system, which has been implemented by KOREATECH recently under the goal of nurturing industry-oriented talents with practical skills, based on the analysis of actual operational practices of advanced overseas universities and the IPP experiences for 2 years. The roles of IPP professor are largely divided into the following three: IPP manager; student career counselor; educator of IPP educational program. During the initial stage of IPP system, the role of IPP manager is most significant. However, as the system is systematically managed and operated, the role of IPP manager gradually decreases, and the role of career counselor becomes more important. Since IPP system is an educational program that gives credits, IPP professor should also perform the role of educator, including designing experiential learning curriculum and evaluation on educational goal accomplishment.

The objective of this research examines the relationships among privacy concerns, self discrepancy, and sense of virtual communities. According to the relevant literature review, we considered information privacy concerns factor as information collection, control, and awareness of privacy practice, and sense of community factor as membership and immersion on virtual communities. This research surveyed for the online community user and employed hierarchical regression model for the moderating effect test. The results of empirical analysis turns out that awareness of privacy concerns practice has negative impact on the self discrepancy, on the other hand, information collection and control factors do not affect. The next finding is internet use duration has moderating effect on the self discrepancy with information control and awareness of privacy concerns practice. The last findings are self discrepancy affect on the community membership and does not affect on the community immersion. It could be a good guide line for the operational direction on virtual community.

Public order management is one of the most important areas in policing. Drawing on the legal framework and policy, this study aims to assess practices of criminal justice practitioners, especially, police and prosecutors, in England and Wales. Using qualitative interviewing, four main themes are identified: (1) an emphasis on a right to protest, (2) police practices on public order management, (3) the development of police/prosecutor liaison, and (4) the value of video evidence. Based upon these findings, several legal, policy and practice implications are drawn. These implications involve a wide range of aspects concerning strategic, operational, and tactical interventions by the police, as well as collaboration between police and prosecutors. Although the criminal justice context in England and Wales is very different to South Korea, some practices and distinctions can be useful to consider in the Korean context. This study suggests that more gains can be made if legislation, policy, and practice across criminal justice nodes can be coordinated and approached holistically.

Recent trends in urban policies show the increasing importance of urban parks. Moreover the park policy and planning are increasingly important for the good urban park system. Comparative studies in the operational system and planning contents of the parks and green space plans of the major cities would be timely and meaningful. This study aims to provide a comparative study in operational system and planning contents of the Parks and Green Space Master Plan at urban scale. Sites include London, New York, Berlin, Sydney and Seoul. Analyses are focused on the master plans and strategy reports of each city. Frameworks for analysis are divided into operational system and planning contents. The results are as follows. First, the Parks and Green Space Plans as an open space planning linked to related resources would contribute to both integrated resources management and practice of the fairness. Second, evolution from quantity to quality of the parks and green space plan enhances revitalization and regeneration. Third, shift from the 'supply oriented plan' to 'need based plan' model provides flexible planning model to meet the demographic change, trend change, preference and use. Fourth, planning agents, enlarged opportunities for participation within each phase, diversified of the participants lead the changes from the passive participation to active one. In order to improve the practicability of the parks and green space master plan, a flexible planning strategy including social awareness changes and park governance is required.

Recently, a variety of new transportation systems have been developed or introduced, but there has been a lot of confusion in the selection process of systems because there is no such domestic cases, and a lack of information on the systems. It does not make sense to analyze the strengths and weaknesses of the systems in a single frame because each system has different characteristics and purposes. It is important to compare the relative values of the systems considering the status of the project site, transport demand, costs, and environmental aspects of cities. In the present paper, the operational system and infrastructure technologies of the bimodal tram developed in Korea were investigated. Based on this, the values for the bimodal tram was compared with similar new transportation systems through several practice cases. It is expected to promote in the practical use of the bimodal tram through this study.

In this paper, we have proposed novel technique to improve maintainability for training vehicle of underwater weapon system. In case of under water weapon, the fire procedure is related with operation of expulsion system in submarines. So the submarine crews should practice the complex fire procedure of weapon system by using training vehicle, which is safer and cheaper than operational weapon. After emitted from submarine, the training vehicle rise to the surface and should be withdrawn from the sea. The recovered training vehicle is transported to maintenance depot and pass through the recycling procedure including disassembling the vehicle, data acquisition & analysis, battery charge, replacing expandable components, testing the captive equipment, and assembling the vehicle. The disassembling & assembling of training vehicle which is composed of watertight section or airframe, is time-consuming work. So in this paper, we have studied the elements of recycling procedure and propose the method to exclude the assembling & disassembling work for maintainability improvement.

Sanitary management practices from 8 packaged meals (Dosirak) manufacturing establishments were surveyd during production and distribution and their microbiological quality of dosirak items marketed in CVS were analyzed. Correlation coefficients were calculated to deternine significant relationships between sanitary management practices and microbiological quality of packaged meals. The results of self evaluation on sanitary management practices indicated 'doing practice well' in personnel and equipment sanitation management but time-temperature control management were practiced satisfactorily only about 55% as compared with the managerial standard guidelines. Significant relationships between the status of actual sanitary management practices and microbiological quality of Dosirak items were not found, but general status of microbiological quality of Dosirak items revealed positive relationship with the size of operational structure and the status of time-temperature control management practices.

The safety and reliablity of nuclear power plant operations relies heavily on the plant operators ability to respond to various emergency situations. It has become standard industry practice to utilize simulators to improve the safety and reliability of nuclear power plants operations. The simulators built for Younggwang#3("YGN#3"), which is based on the Korean Standard Nuclear Power Plant ("KSNPP")design, has been developed precisely for this purpose. The YGN#3 simulator is the first simulator in Korea to be developed locally and is now operational on site. A particular attention was placed on the development of CPC/COLLS safety system which is unique to the YGN#3. The effort to develop CPC/COLLS simulation model has been successful and plans exist for applying this model to simulator projects in the future.jects in the future.

It has been recognized that the compressibility of hydraulic fluid, which is characterized by the value of its bulk modulus, heavily affects on the system behavior and performance. In practice, the value of the oil bulk modulus varies by the operational and structural characteristics of the hydraulic system. This study presents the theoretical derivation of the effective bulk modulus and describes an experimental impulse technique that allows accurate measurement of oil effective bulk modulus with pressure variation in a hydraulic system. Experimental and analytical results show that the value of the effective bulk modulus varies a lot in low pressure region by the effect of entrained air, while the effective bulk modulus can be estimated just using the oil and container bulk modulus on the other high pressure region.

Wastewater process models are the essential tools for understanding relevant aspects of wastewater treatment system. Wastewater process modeling provides more options for upgrades and better understanding of new plant design, as well as improvements of operational controls. The software packages (BioWin, GPS-X, Aqua designer, etc) solve a series of simulated equations simultaneously in order to propose several solutions for a specific facility. Research and implementation of wastewater process modeling in combination with computational fluid dynamics enable testing for improvements of flow characteristics for WWTP and at the same time exam biological, physical, and chemical characteristics of the flow. Application of WWTP models requires broad knowledge of the process and expertise in modeling. Therefore, an efficient and good modeling practice requires both experience and set of proper guidelines as a background.
