Background: Primary health care (PHC) plays a major role to ensure the basic right and equal distribution of the essential health care services. This study presents comparative analyses of PHC in Korea and Uzbekistan, discusses the existing scenario and the challenges, and provides recommendations. Methods: This study reviewed secondary data from Korea's National Statistical Information Service and the State Committee of the Republic of Uzbekistan on Statistic, regulatory legislation, research reports, and policy papers by research and international institutions. We focus on comparing input and outcome health data, PHC structure, and health expenditure. Results: Overall health status of the population in Korea is better than in Uzbekistan; both countries achieved more than 95% immunization coverage. The reforms implemented in both countries provide initial health care service delivery. However, there are several challenges such as the distribution of the staff between urban and rural areas and interest of the graduates on specialization rather than working in PHC system. Conclusion: PHC plays an important role in the provision of medical services to the population, addressing both health and social problems; it is the best tool for achieving universal coverage for basic health needs of the population. The community health practitioners in Korea and nurses in Uzbekistan plays main role in universal coverage through providing essential health care services. Continuous reform of the PHC system should be directed to strengthen the capacity of the PHC staff in health promotion knowledge and activities as well as to encourage population to improve their own health.

The existing underground trenchless methods use reinforcing rod in steel tube to obtain structural stiffness. However, there are some problems such as inconvenience of work and expensive material fee which are resulted from limited working space and reinforcing work. To resolve these problems, a new trenchless method, namely P.S.T method (Prestressed Segment Tunnel Method), is developed which uses joint to connect the steel segment and form erection structure in underground construction. Further, installing strands for prestressing. In order to evaluate the flexural capacity of the P.S.T method structure, experiment was conducted. The parameters considered in the experiment are the span-to-depth ratio, diameter of steel tube at corner, prestressing force and welding of joint. Altogether examining the flexural behavior, the effect of deflection in structure according to different parameters has also been analysised.

Despite the importance of disaster management officers of disaster management agencies at the local government to protect the lives of civilians and their properties, there is a lack of research or literature in their roles and responsibilities. In fact, there is a urgent need to set clear roles and responsibilities for them. This study scrutinizes how to disaster managers should behave in specific setting that differentiates from other administrative managers based on domestic and foreign literature review. Although, the role of disaster manager seem to be similar to administrative manager, there are some differences particularly in the areas that disaster manager has to work as an expert in saving lives and properties that has to be further emphasized. When working on disaster management process of prevention and resoration, the key task are based on mid and low level officers. On the other hand, preparedness and response process that involve rapid decision making and cooperation with other department, persuasion of local residents and resource pooling are carried out by mid and high level managers because it requires control capacity and decision making skills.

The previous study was conducted to develop an air source multi heat pump system that could be operated with the solar collector and air source heat exchangers as heat source of the system. There is a winter-sowing problems in air source multi heat pump system when the outdoor temperature goes down under freezing point. The winter-sowing problem was solved by adapting R-22 refrigerant as working fluid in the previous study. However, when the system operated at high temperature, another problems are come out such as overheating of the solar collector outlet which lead to the superheat of the compressor inlet of the heat pump system. The condition could deteriorates a compressor in some case. In this study, we installed the anti-superheating devices on the previously developed system. As results of system performance test, COP of the system with anti-superheating technique is 2.4. It is a little improved COP compare to previous study's 2.23. In the results of multi heat source heating system, during operating solar collector, COP is relatively high between $200\;W/m^2$ and $400\;W/m^2$ solar intensity. It is recommended to extend the study on performance optimization with balancing the solar collect and capacity of compressor at higher solar irradiation conditions.

The purpose of this paper is to investigate an analytical approach for opening performance evaluation of the nuclear pressure safety valve based on standard codes such as ASME or KEPIC. It is well-known that safety valve is considered as one of pressure relief valves for protecting a boiler or pressure vessel from exceeding the maximum allowable working pressure. When pressure in a container reaches its set pressure, the safety valve commences discharging the internal fluid by a sudden opening called as popping. Safety valve is usually evaluated by set pressure, full open, blow-down, leakage and flow capacity. The test procedure and technical requirement for performance evaluation is described in international code of ASME code such as BPVC. The opening characteristics of steam safety valve can be analyzed by computational fluid dynamics (CFD) and steam shaft dynamics. First, the flow analysis along opening process is simulated by running the CFD models of the ten types of opening steps from 0 to 100%. As a analysis result, the various CFD outputs of flow pattern, pressure, forces on the disc and mass flow at each simulation step is demonstrated. The lift force is calculated by using the forces applied on disc from static pressure and secondary flow. And, the effect of huddle chamber or control chamber is studied by dynamic analysis based on CFD simulation results such as lift force. As a result, dynamics analysis shows opening features according to the sizes of control chamber.

One way to increase public revenue from public parking spaces is by improving the way parking meters gather data. Improved parking meters have evolved that increase car park revenue as well as efficiency in service and operations. It provides parking meters with the capacity to provide real-time information. This information consist primarily of the status of parking spaces (it indicates which expired metered spaces have parked vehicles.) The technology consists of sensors located at meters that report on their condition (i.e. whether it is working or if it is expired). This information is processed by a microprocessor and then sent via an internal wireless modem to the server. This server then processes the information from all the parking meters and sends it to the public institution in charge of them. This system also provides verification of parking permits. For example, disabled people with special license plates can be automatically approved for parking in designated places.

1002 Students in the dept. of the dental laboratory technology of 8 college around the nation were surveyed on the three items-the professional attitude, their job-plan after graduation and the conditions and causes exerting influence on their choice of a job. 1. professional Consciousness About the purpose to take a job, 41.8% of all the students replied the economic stability. Another question is on the formation of the professional consiousness. 34.7% said they didn't accomplish it yet, while 32.1% did. This shows that the number of those hwo are resolute isnt's too low in comparison with those not. On the considering factors when they take a job, stability was first favored, with the capacity to improve itself and then profitability following on as second and third. 2. Job-plan after School 78.9% of all wanted to work in their major field as a dental technician. About their knowledge of the job, 60.4% know it well; though, their confidence in getting the job is close to the low level wholly. 3. Factors Having Influence on the selection of a job About the most decisive point in one's choice of job, 37.3% selected first the degree of completion of his major-field knowledge and skill. The most critical person when choosing his job was himself, a great number of students answered. About the working area favored, 52.9% first answered Seoul on the reason why it is a familiar place where their family or relatives have already lived and the special knowledge related to the job is easilly accessed.

Strengthening reinforced concrete (RC) beams with openings by using aramid fiber reinforcement polymers (AFRP) on the beams' surfaces offers a useful solution for upgrading concrete structures to carry heavy loads. This paper presents a repairing technique of the AFRP sheets that effectively strengthens RC beams, controls both the failure modes and the stress distribution around the beam chords and enhances the serviceability (deflection produced under working loads be sufficiently small and cracking be controlled) of pre-cracked RC beams with openings. To investigate the possible damage that was caused by the service load and to simulate the structure behavior in the site, a comprehensive experimental study was performed. Two unstrengthened control beams, four beams that were pre-cracked before the application of the AFRP sheets and one beam that was strengthened without pre-cracking were tested. Cracking was first induced, followed by repair using various orientations of AFRP sheets, and then the beams were tested to failure. This load was kept constant during the strengthening process. The results show that both the preexisting damage level and the FRP orientation have a significant effect on strengthening effectiveness and failure mode. All of the strengthened specimens exhibited higher capacities with capacity enhancements ranging from 21.8 to 66.4%, and the crack width reduced by 25.6-82.7% at failure load compared to the control beam. Finally, the authors present a comparison between the experimental results and the predictions using the ACI 440.2R-08 guidelines.

The tunnel type spillways is under construction to increasing water reservoir capacity in Dae-am dam. Cutting-slope adjacent to outlet of spillways had been originally designed to be 63 degrees and about 65m in height. Examination is carried out in preceding construction that it is caused to some problems possibility which of machine for slope cutting couldn't approach to the site, blasting for cutting slope might have negative influence on highway and roads nearby, and fine view along the Tae-hwa river would be eliminated. In order to establish stability of tunnel and more friendly natural environment that we are carry out detailed geological surface survey and analysis of slope stability. So, we are design and construct for tunnel excavation with possible method that it is keep up natural slope. The result of survey and analysis that natural slope was divided 3 zone(A, B, C zone). In A and B zone, in first removed floating rock, high tensile tension net is install that it prevent of release and falling of rock, in order to security during under working. In addition to, pre-stressed rock anchor is install purpose of security during tunnel excavation because of fault zone near vertical developed above excavation level. Zone C is relatively good condition of ground, design is only carry out random rock bolt. All zone are designed and constructed drainage hole for groundwater and surface water is easily drain. Desinged slpoe is harmony with near natural environment. Successfully, construction is completed.
