Determining of Strategic Business Units in the organization is a major critical process for improving the organizational performance. On increasing the demands for extension in function of health center, many health centers are trying to provide the various services. But most health center determined the kind and level of service without scientific considerations. The purposes of this study are to develope the model for determination of strategic business units in health center and to test the availability of implementation for it. Our model is rooted from the McKinsey matrix analysis of Product Portfolio Analysis which used widely in marketing field. We modified the evaluation criteria of the McKinsey matrix analysis for health care field appropriately. Our evaluation criteria are categorized into two concepts; contribution of service, availability of service. At first, in terms of contribution of service, market size, market growth rate, needs and demands of regional people, existences of alternative services in that region, correspondence with health policy. The other component, availability of service are included the availability of manpower, financial availability, the level of knowhow on service, acceptance of health care manpower. In the result of analysis, we could conclude that antismoking and antialcoholics education programs, health screening program are important strategically in that aspects of contributions and availability of services. Also, vaccination program is important in that aspect of service availability and diet and exercise program, health library are meaningful in the aspect of service contribution. Therefore, we think that efforts to investigate the evaluation criteria for priority setting or determination of service area in health center are useful challenges.

Renewable energy is emerging as a way for the government to carry out its 2030 carbon-neutral policy. In this regard, the demand for wind turbine generators for renewable energy is increasing. As a result of restrictions due to civil complaints, offshore wind power generators are actively being developed. At this time, offshore wind power generation has higher maintenance costs, material costs, and installation costs compared to onshore wind power generation. So, an economic evaluation that calculates imports and costs is an important task. The levelized cost of energy (LCOE) is an economic evaluation index used in the energy field. In this paper, based on AEP calculated by windpro, the LCOE calculated by the wind power cost estimation model published in the NREL Economic Analysis Report, installing one 15 MW unit and installing one 20 MW unit and seven units were reviewed and analyzed. As a result, AEP was calculated as 0.140($/Kwh) for the installation of a single 15 MW, 0.142($/Kwh) for the installation of a single 20 MW, and 0.119 ($/Kwh) for the installation of a 20 MW farm. Therefore, it was confirmed that the installation of the single 20 MW was more economical than the installation of the single 15 MW and the installation of the 20 MW farm was most economical.

The General program evaluation guide is intended for use by managers of both deployment and R&D programs within the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE), although most of the examples of evaluations pertain to deployment programs(EERE,2006). It could help managers determine what kinds of timely adjustments may be needed in program design or implementation to improve the rate or quality of achievement relative to the committed resources. To consider the adaptation of the method in Korea, we have studied the evaluation case for solar america initiative using cost-benefit evaluation. The President's Solar America Initiative (SAI) was launched in January 2006 as part of the administration's Advanced Energy Initiative. The SAI has a goal of installing 5-10 GW of photovoltaic (PV) systems in the U.S. by 2015 and 70-100 GW of PV systems in the U.S. by 2030. The evaluation report presents estimates of the potential benefits should the SAI PV installation goals be achieved. For this analysis, the areas researched include energy, economic, and environmental benefits. As a result, research suggests that 500 MW of PV may have been enough to avoid lackout. The ability of PV to prevent specific blackouts will depend on very specific information on where the PV installations are installed and their ability to relieve pressure on the high stress points on the grid. While this level of detail is outside the scope of this study, it appears that there will be some potential benefit for blackout prevention should the SAI PV goals be achieved.

The purpose of this study is to analyze the perceptions and difficulties of early childhood teachers about the revised Nuri Curriculum, and to provide basic data for stable operation. 128 early childhood teachers in Seoul and Gyeonggi Province were surveyed, and frequency analysis and chi-square test were performed using the SPSS 27.0 program. As a result of the study, teachers recognized the difference in child evaluation in the Nuri Curriculum and the revised Nuri Curriculum, and recognized the difference in the evaluation method the most. Some of the items on perception showed a significant difference according to the educational experience of teachers. Teachers recognized 'autonomy' as the focus of early childhood evaluation, and at the same time recognized that it was the biggest factor that made child evaluation difficult. The interactive peer-to-peer workshop showed the highest demand for early childhood evaluation. The results of this study will be the basis for finding ways to support teachers in charge of early childhood evaluation in the revised Nuri Curriculum.

The equivalent boundary conditions have been applied to the front door panel forming process, in order to demonstrate its reliability and validity. The elongation in the bead forming process is applied to the binder wrap process as the equivalent displacement boundary condition and the restraining force in the drawing process is applied to stamping process as the equivalent force boundary condition. The result calculated with the equivalent boundary conditions shows closer coincidence with the experimental result than simulation with different boundary conditions. The numerical result fully demonstrates that drawbead forming simulation for calculation of equivalent boundary conditions is necessary and effective.

Openness to outside is one of the most critical advantages for high-rise buildings. However, the effect of openness can be decreased if it is blocked by other high-rise buildings, especially built within the building complex of commercial district. The purpose of this study is to identify the horizontal openness of high-rise residential buildings by comparing 3 different cases of building arrangement type. A new method of evaluation has been introduced on the basis of distance to measure the openness including the matter of securing privacy. As a result of this study, comparative analysis was possible and relatively plentiful results of analysis could be drawn out. Through the process of analysis, this study set the evaluation indicators suitable to the analysis of openness of unit households. Thereby, the results of this study are expected to be used as useful basic data in planning high-rise mixed-use buildings.

Recently, the concern for the environmental noise has increased due to the growing of the living standard. The environmental noise regulations based on the equivalent noise level are widely used. However, the noise level, which Is based mainly on the magnitude with A-weighting, the important characteristics of noises in frequency and time domains and the impulsive nature cannot be assessed properly. These can have substantial effects on how human respond to noise. Therefore, the noise evaluation methodology based on the sound quality rather than the equivalent noise level can be more suitable to represent human response to the environmental noise. This paper describes the study on environmental noise quality analysis for various noises. A cluster analysis was carried out and the noises were classified into several clusters using the values of sound quality metrics. The classification was confirmed by comparing time and frequency characteristics of the noises. And then the result of Jury testing was analysis.
