The energy economic analysis of the standard rural house model with PV system was performed based on annual energy demand calculation using the EnergyPlus to contribute in reducing building energy which occupies 25% of national energy consumption and in developing a low-energy & eco-friendly house model. Two types of PV system installation was considered to cover electricity demand for cooling, electric, and heating devices. For the selected house model, heating energy demand is 7 times higher than cooling energy demand. For the Case1, it is favorable to use electricity from PV system for cooling and electric devices and to sell surplus electricity. For the Case2, it is favorable to use electricity from PV system for cooling, electricity and heating devices and to sell surplus electricity. Considering the installation cost of PV system and heat pump air conditioning system, the break-even point of Case1 and Case2 are about 13 and 11 years respectively. Although the installation cost of Case2 is more expensive, Case2 provides three times more profit than Case1 after the break-even point. Because the expected average life time of the selected PV system is 25 years, Case2 is more favorable option for the given standard rural house model.

In order to analyze wave propagation, tidal current, and sediment transport in the vicinity of the Gaeya open channel, it was classified into before(CASE1W) and after(CASE2W) installation of various artificial structures, and the calculation results for CASE1W and CASE2W were compared. For wave propagation, the results of incident and reflected waves were derived using the SWAN numerical model, and the tidal current velocity results were derived using the FLOW2DH numerical model for tidal current. The results of the SWAN numerical model and the FLOW2DH numerical model became the input conditions for the SEDTRAN numerical model that predicts sediment transport, and the maximum bed shear stress and suspended sediment concentration distribution near the Gaeya open channel were calculated through the SEDTRAN numerical model. As a result of the calculation of the SWAN numerical model, the wave height of CASE2W was increased by 40~50 % compared to CASE1W because the incident wave was diffracted and superimposed and the reflected wave was generated by about 7 km long northen jetty. As a result of the calculation of the FLOW2DH numerical model, According to the northen breakwater, the northen jetty and Geumrando, CASE2W was calculated 10~30 % faster than CASE1W in the tidal current of the Gaeya open channel. As a result of the calculation of the SEDTRAN numerical model, the section where the maximum bed shear stress is 1.0 N/m² or more and the suspended concentration is 80mg/L or more was widely distributed in the Gaeya open channel from the marine environment by the complex wave field(incident wave, reflected wave and tidal wave) and the installation of various artificial structures. it is believed that a sedimentation phenomenon occurred in the Gaeya open channel.

Objectives: The purpose of this study was to evaluate the quality of reporting for case reports published in Journal of Oriental Neuropsychiatry from year 2018 to 2021 compared with year 2013 to 2017 in order to recommend ways to improve the quality of case reports published in the future. Methods: To evaluate the quality of case reports identified by electronic searching in Oriental medicine Advanced Searching Integrated System (OASIS) and by hand searching from archives on peer review system of Journal of Oriental Neuropsychiatry using CAse REport (CARE) guideline. The researcher assessed the quality of reporting based on the CARE guideline as 'Sufficient', 'Not-Sufficient', 'Not-Applicable', and 'Not-Reported' for case reports published from 2018 to 2021 in Journal of Oriental Neuropsychiatry. In addition, it was compared with previous case reports published from 2013 to 2017. Results: Finally, 17 case reports were included for the assessment. General quality of reporting for case reports published from year 2018 to 2021 was improved compared with that of previous case reports published in 2018. The maximum value (46.4%→60.7%, 14.3% increase), the minimum value (22.2%→32.1%, 9.9% increase), and the median value (39.3%→50.0%, 10.7% increase) of the report rate evaluated as 'Sufficient' were generally improved. The maximum value (53.6%→50.0%, 3.6% decrease), minimum value (25.9%→21.4%, 4.5% decrease), and median value (35.7%→32.1%, 3.6% decrease) of the report rate evaluated as 'Not-Sufficient', the maximum value of the report rate evaluated as 'Not-reported' (40.7%→25.9%, 14.8% decrease), the minimum value (14.7%→10.7% decrease), and the intermediate value (14.7% decrease) were also generally improved. Four items (8b, 8d, 10c, and 13) were evaluated as 'Not-Reported'. These items seem to be items that need urgent improvement along with 8c, which showed a significant decrease in reporting rate. Conclusions: There are needs to improve the quality of case reports in Journal of Oriental Neuropsychiatry by comparing case reports published from year 2013 to 2017 with case reports published from year 2018 to 2021. To improve the quality of case reporting, sufficient education at the academic level should be provided on thesis preparation methods. It is also necessary to develop a tool for evaluating the quality of case reporting that reflects characteristics of Korean Medicine.

The purpose of this study is to propose a different classification method for keeping a record of cases. After proving that criminal case files should be counted as one type of case files, based on their characteristics and characteristics, this research analyzes the current process of criminal case filling at Public Prosecutor's Office to point out some problems. This study suggests a new classification system: at first, each case gets classified based on a case: secondary, the data gets further assorted by the chronological procedures. The classification approach, which is adopted from MoReq 2's Workflow method, is more adjustable to the new electronic filing system.

Generally, larger sample size leads to a greater statistical power to detect a significant difference. We may increase the sample size for both case and control in order to obtain greater power. However, it is often the case that increasing sample size for case is not feasible for a variety of reasons. In order to look at change in power as the ratio of control to case varies (1:1 to 4:1), we conduct association tests with simulated data generated by PLINK. The simulated data consist of 50 disease SNPs and 300 non-disease SNPs and we compute powers for disease SNPs. Genetic Power Calculator was used for computing powers with varying the ratio of control to case (1:1, 2:1, 3:1, 4:1). In this study, we show that gains in statistical power resulting from increasing the ratio of control to case are substantial for the simulated data. Similar results might be expected for real data.

This is a report on the cases of benign mediastinal tumors in the Department of Thoracic and Cardiovascular Surgery, Chonnam University Hospital during the period from 1961 to 1975. Age distribution was from 18 to 62 years old with the highest incidence in the 3rd decade, and sex ratio of male to female was 7 : 8. The tumor were classified as follows; 6 cases of teratoma 5 cases of neurogenic tumor one case of pericardial cyst one case of cystic hygroma one case of dermoid cyst one case of bronchogenic cyst. The symptomatic patients were 10 cases (66.7%) and asymptomatic patients were 5 cases (33.3%), who were found incidentally by routine chest n-ray. The symptoms occurred by compression to the adjacent nerve system in 7 cases, by perforation into the lung with infection in one case of teratoma and by infection of bronchogenic cyst in one case and of teratoma in one case. Complications were Pancoast's syndrome including Horner's syndrome 2 cases, middle lobe syndrome 2 cases, intercostal neuralgia 1 case and bronchitis 1 case. All tumors were surgically resectable with good recovery. In all 10 cases of symptomatic patients, their symptoms disappeared dramatically after operation.

In this paper, the natural convection in a square enclosure, partly heated from below, with two adiabatic vertical wall and one upper horigental wall is studied nomerically. In numerical study, SIMPLE(Semi-Implicit for Pressure Linked Equation) algorithems are applied for the integration of momentum and energy equation. The grid size used in this study is the coordinates of size (22$\times$22). As a result of numerical analysis, the initial fluid flow depends on the thermal diffusion, but, as time passes, the fluid flow depends on convection and buoyancy of the enclosure. In Case 1, the heating region was been in the central position of the bottom wall. In case 2, the heating region was in the left position of the bottom. In case of Case 1, the lapse time of sensing the temperature of 72$^{\circ}C$ is approximately 15 sec almost at the same time in the coordinates (6, 22), (11, 22). In case of Case 2, the lapse time in the coordinates (6, 22), (11, 22) was 27 sec, 25 sec repectively. Also in case of Case 1 or Case 2, the gradients of y-position of the two sensors are transposed each other.

Installation of ceiling type unit is achieved by one of efforts for agreeable classroom environment embodiment along with economic growth. But research about changing the position of ceiling type unit is lacking in present. Therefore, this thesis is to study the thermal environment of 5 different position cases of ceiling type, namely Case A, B, C, D, E. Here, Case C is the case that has the position of ceiling type center of the classroom and the other 4 alternatives are 0.7 m away from the Case C according to x and z axis. In this thesis temperature distributions, air current distribution, heat amenities such as PMV of occupants are analyzed as the environmental factors. Through these factors, Case C and Case D are the better position alternatives than the alternatives of Case A, Case B and Case E because the latter cases the air current reaches directly to indoor occupants so that occupants feel chilly. This thesis has a conclusion under the condition of only one inlet air temperature and seat arrangement. But afterwards more inlet air condition and seat arrangement must be considered.
