  • Recently, small scale hydropower needs to be developed due to its clean, renewable and abundant energy resources. However, suitable draft of hydro-turbine body in combination with differences in wheel blade shapes is not determined yet in the range of small hydropower and it is necessary to study for the effective draft in combination with type. Therefore, watermill shaped of 250mm diameter. hydro-turbine aiming 20 watt class generator is adopted in this study because of its simple structure and high possibility of applying to small hydropower. The result shows that effective draft for the turbine body is variable concerning the size of turbine and flow rate of water. Thus, the difference of water depth between fore and aft turbine body contributes to the increase of torque, angular momentum and power output.

  • Now the most important thing in fashion industry is find out the fashion sensibility and preference of customers exactly. Thus it is needed that fashion sensibility is connected with formative properties in clothing. The purpose of this study is to clarify the relationship between the fashion sensibility and the formative properties in clothing. 91 kinds of costume samples have been selected from photographs in fashion magazines under color combination, inside form, texture, pattern type in clothing. I have measured fashion sensibility by using Semantic Differential method. The obtained data were analyzed by GLM, discriminant analysis. The results of analysis are as follow; 1. The discriminative images were significant difference in formative properties - color combination was related to attractiveness, inner form to decorativeness, pattern to harmony and texture to surface of soft and hard in clothing. 2. fashion sensibility was significant relationship with formative properties especially inner form in clothing. And the trimming was identified as gorgeous and feminine. 3. Preference, Buying needs, Riches and Pleasant were significant relationship with formative properties in clothing especially color combination and texture.

  • Objectives: This study aimed to compare effects on glycemic control and weight loss between the metformin/dapagliflozin combination and the metformin/sitagliptin combination in type 2 diabetic patients. Methods: This study retrospectively reviewed the medical records, from January $1^{st}$ 2015 to March $31^{st}$ 2016, of type 2 diabetic patients who were older than 18 and were prescribed with dapagliflozin or sitagliptin in combination with metformin. Hemoglobin $A_{1c}$ ($HbA_{1c}$) levels and weights were measured every 3 months. Results: The dapagliflozin group showed a greater decrease in $HbA_{1c}$ levels after 3 months (-0.75% vs. 0.01%, P<0.001), 6 months (-0.36% vs. 0.08%, P=0.029), and 9 months (-0.53% vs. 0.08%, P=0.046) compared to the sitagliptin group. Also, the dapagliflozin group showed a greater significant decrease in the rate of change in $HbA_{1c}$ levels after 3 months (-0.09 vs. 0.01, P<0.001), 6 months (-0.04 vs. 0.01, P=0.031), 9 months (-0.07 vs. 0.02, P=0.029), and 12 months (-0.05 vs. 0.05, P=0.047). Furthermore, the dapagliflozin group showed a greater decrease in amount of weight change after 3 months (-2.46 kg vs. 0.37 kg, P<0.001), 6 months (-3.02 kg vs. 0.13 kg, P<0.001), and 9 months (-2.27 kg vs. 0.50 kg, P=0.002). Finally, the dapagliflozin group showed a greater decrease in the rate of change in weight after 3 months (-3.10% vs. 0.52%, P<0.001), 6 months (-3.83% vs. 0.21%, P<0.001), 9 months (-2.84% vs. 0.79%, P=0.002), and 12 months (-4.91% vs. 0.44%, P<0.001). Conclusions: It was concluded that dapagliflozin is more effective than sitagliptin for type 2 diabetic patients.

  • Endobronchial tuberculosis is a serious disase because it frequently leaves airway obstruction as the complication, and the treatment of airway obstruction is generally troublesome. In the tumorous type of endobonchial tuberculosis, the bronchial patency is partially or completely compromised with lymph node contents when the necrotic focus of the lymph node ruptures into the bronchial lumen to form a bronchoglandular fistula. To investigate the transition of endobronchial lesion and to evaluate the therapeutic role of bronchoscopic electrocautery in the tumorous type of endobronchial tuberculosis, we performed electrocautery in addition to the combination chemotherapy with steroid and anti-tuberculous drugs in two cases which had airway obstruction proximal to lobar bronchus with the impairment of pulmonary function. We also treated another two cases only with chemotherapy and we have followed up four cases over a 36-month period. In cases that bronchoscopic electrocautery was done, the bronchial patency was completely restored and the impairment of pulmonary function disappeared just after cautery and these effects have remained for 12 months or more. But in cases of medical treatment only, bronchial stenosis was inevitable as the tumorous type of endobronchial tuberculosis changed to the stenotic type with fibrosis. It can be concluded that bronchoscopic electrocautery can nip the occurence of bronchial stenosis in the bud when it is applied in addition to combination chemotherapy with steroid and antituberculous drugs in the tumorous type of endobronchial tuberculosis.

  • This research was for the investigation and analysis of the illustration of modular construction application which is different use by each school facility since modular construction related examples are rare in domestic situation, and it has a limitation because of its being basic research material for generating the basic form of modular construction. The research results are as followings. First, in case of school facility from illustration investigation results, module measurement of class modulation is as similar as $3m{\times}10m$, but in resident facility the planning of more flexible plane shape can be possible since modules of 6 cases are free and various, and facade form of various types can be appeared by combination of module unit. Second, as a result of the generated characteristics in compared analysis of representative examples, school facilities were highly indicated for movability and duration reduction areas, and the flexibility, economic efficiency, and environment-friendliness was indicated low relatively. Third, the basic planning types of modular construction can be largely divided into layered type, horizontal (straightway) type, and compound type. The layered type has a short traffic line and facility system and is appropriate for the low-rise form unless separate construction method is used since it is susceptible to load. The horizontal type is advantageous for securing an opening since it has wide extent in light but has a long traffic line and facility system. Finally, the compound type can be possible for planning of various forms but needs the combination of various unit modules and traffic line and facility plan for it can be difficult.

  • 그동안 데이터 개방, 기술수용이론 등 빅데이터 활용의 영향요인에 대한 법·정책적 연구는 다수 있었으나, 제약선 역할을 하는 개인정보 규제요인 또는 데이터 결합요인이 빅데이터 활용에 미치는 영향에 대한 실증연구는 거의 없었다. 이에 본 연구는 델파이 분석(Delphi Analysis)을 통해 빅데이터 활성화에 부정적(-) 관계를 보이는 개인정보 규제요인과 긍정적(+) 효과를 보이는 데이터 결합요인이 무엇으로 구성되는지 요인의 우선순위를 시론적으로 탐색하였다. 델파이 분석결과, 개인정보 규제요인은 가명정보 등 활용제도 도입, 개인정보 비식별화 근거 명확성, 데이터 결합규정 명확성, 개인정보 정의 명확성, 개인정보 동의 용이성, 개인정보 감독기구 통합, 개인정보 법률간 정합성, 법령위반시 적정 처벌강도, EU GDPR 비교시 적정 과징금 순으로 상위요인이 조사되었다. 다음으로 데이터 결합요인은 결합 비식별성, 결합데이터 표준화, 결합 책임성, 결합기관 유형, 경합경험, 결합 기술가치 순으로 조사되었다. 이러한 연구결과는 빅데이터 활성화를 위해 개인정보 규제와 데이터 결합정책 설계 시 어느 구성요인을 우선적으로 제도개선 해야 하는지 시사점을 제공한다.

  • In the conventional metallothermic reduction (MR) process for obtaining tantalum powder in batch-type operation. it is difficult to control morphology and location of deposits. On the other hand, a electronically mediated reaction (EMR) process is capable to overcome these difficulties and has a merit of continuous process, but it has the defect that the reduction yield is poor. MR-EMR combination process is a method that is able to overcome demerits of MR and EMR process. In this study, a MR-EMR combination process has been applied to the production of tantalum powder by sodium reduction of $K_2$TaF$_{7}$. The total charge passed through external circuit and average particle size (FSSS) were increased with increasing reduction temperature. The proportion of fine particle (-325 mesh) was decreased with increasing reduction temperature. The yield was improved from 65% to 74% with increasing reduction temperature. Considering the charge, impurities, morphology, particle size and yield, an reduction temperature of 1,123 K was found to be optimum temperature for MR-EMR combination process.
