In accordance with Article 33(8) of the Korean Medical Law, it is stated that a medical person cannot open or operate a medical institution by borrowing the name of another medical person. However, the publicity of medical care is threatened by the recent illegal network dental clinics. The purpose of this study is to investigate the actual condition of illegal network dentistry and to analyze the cases and to find out the reason why the prohibition of double opening & operating of medical institution. As a result, the illegal network dental clinics treated less health care insurance treatment such as dental caries and periodontal treatment than general dental hospitals. In contrast, the rate of implementation of illegal network dentistry was high in endodontics treatment and extraction, which could lead to uninsured treatments such as crowns and implants. As a result of Supreme Court precedent analysis, it is concluded that illegal act is not only the opening of a medical institution by borrowing the name of other medical personnel, but also the duplicated operation which has the authority to make decision about management matters of medical institutions. The results of the patient's case survey also showed that excessive dental treatment due to such as dental staff incentive system. In conclusion, the illegal network dental clinics not only threatens the oral health of the public, but also causes leakage of health insurance premiums. In other words, the ban on opening and operating the multiple medical institution should be strictly applied as a strong protection device for protecting the patient in dental case.

The operation of a five day workweek seems to be increased continuously, Many city-workers will make good use of their spare time and search after a lot of devices that can seek for the maximum value of leisure utility. The demand of potential customers that want to enjoy weekend in farming villages is coming out greatly. That is, the condition of users that will travel the farming villages is getting better. But the actual states of farming villages are not ready in many parts yet. Therefore we must activate the tourist attraction in farming villages that can be satisfied the city-workers' expectation. And after making the sightseeing environment infrastructure, we must develop the programs intimate with environment, improve the sightseeing agricultural management and consolidate various systems as soon as possible. So in this study, after investigating the demand preference degree of city-workers, I tried to grope an activation plan with the base which will reach. Being more urgent what more, not the simple sightseeing agriculture that the farming experience was the focus of, but it is very important to develop the program of environment sightseeing agriculture. It will lay the stress on playing and education culture which city-workers can enjoy and experience. And with constructing the base facility like a city form, we must develop cheap and various goods and the execution of modernized weekend farms. For this, first the consciousness conversion against the customer management of farmers must precede and the change of government policy and the support polity is important. I hope that this study with the five-day workweek has the chance to contribute in the economic growth of farming villages and efficient use and management of the natural environment resources through the activation of sightseeing agriculture.

The public health service center and its branch are, as one of public institution, responsible for providing non-profitable medical service to local residents, which can't be addressed by private medical institutes. In addition, as a planning coordinator, they need to manage local medical resources effectively to make sure local residents can be offered good-quality health service fairly and impartially. The purpose of this study was to highlight the importance of physical therapy in public health service center's successful role performance, one of treatment to which local residents had a direct access. For attaining the purpose, an investigation was made into the actual facilities of public health service center and its branches in North Cholla province, the extent of use of physicaltherapy room, and the general characteristics of physical therapists. And literatures concerned were referred to. As a result, the dominant opinion was that the current physicaltherapy room shoulder be more reinforced(38.9%) or that it should he kept as it was(46.5%). Besides, the physical therapists investigated still were serving in a poor working condition. To elevate the quality and quantity of medical service, the current way to employ expert personnels temporarily or not to guarantee the position of physiotherapists should be removed immediately. Instead, physicaltherapists should be employed as regular public official. As, in home-visit project, physiotherapist are expected to play a bigger role in rehabilitation care or the management of patients with chronic disease, the physicaltherapy room should be increased and more physicaltherapists should be provided to health service institutions.

The extruder type is classified as screw type and non-screw type in terms of the extrusion method. The screw type extruder, which is the most frequently used, is classified as the single screw extruder and the multi-screw extruder. They are classified as vertical type and horizontal type in terms of structure; and those for compounding and for forming in terms of function. The single screw extruder is a universal extruder, most of which is suitable for the extrusion forming of thermoplastic resin. The multi-screw(two-screw, three-screw and four-screw) extruder can increase the extrusion power using the engagement of the screw flank. The single screw extruder does not have a good mixing ratio of the raw material and stable extrusion power, while it has low construction cost and operation cost. In this study, the single screw extruder, which has many weak points compared with the multi-screw extruder, was studied. There have been many studies on the single screw extruder, and they led to its significant development. The existing study method, however, had complex analysis processes and required much time. In this study, the CFD was applied to the performance test and analysis of the extruder, and the optimal design condition of the extrusion power for the screw and die of the single screw extruder was found by comparing the analysis results with the actual performance measurement of the single screw extruder.

Local wall thinning and integrity degradation caused by several mechanisms, such as flow accelerated corrosion (FAC), cavitation, flashing and/or liquid drop impingements, are a main concern in carbon steel piping systems of nuclear power plant in terms of safety and operability. Thinned pipe management program (TPMP) had been developed and optimized to reduce the possibility of unplanned shutdown and/or power reduction due to pipe failure caused by wall thinning in the secondary side piping system. This program also consists of several technical elements such as prediction of wear rate for each component, prioritization of components for inspection, thickness measurement, calculation of actual wear and wear rate for each component. Decision making is associated with replacement or continuous service for thinned pipe components. Establishment of long-term strategy based on diagnosis of plant condition regarding overall wall thinning is also essential part of the program. Prediction models of wall thinning caused by FAC had been established for 24 operating nuclear plants. Long term strategies to manage the thinned pipe component were prepared and applied to each unit, which was reflecting plant specific design, operation, and inspection history, so that the structural integrity of piping system can be maintained. An alternative integrity assessment criterion and a computer program for thinned piping items were developed for the first time in the world, which was directly applicable to the secondary piping system of nuclear power plant. The thinned pipe management program is applied to all domestic nuclear power plants as a standard procedure form so that it contributes to preventing an accident caused by FAC.
