Purpose: This study analyzed building heating, cooling, and lighting energy performance and power generation performance under various climate zones in accordance with Solar Signage Semi-transparent window application. Method: American climate areas, them being tropical, desert, maritime, and microthermal, have been selected and 40%~80% window wall ratio (WWR) has been established in relation to five Solar Signage Semi-transparent windows. Designbuilder, building energy analyzation software, was used to model office building and simulate. Result: Total energy consumption presented Phoenix was highest, followed by Miami, Ann Arbor, with San Francisco being the lowest. The smaller the WWR the higher the heating energy consumption at San Francisco and Ann Arbor appeared with G1 window confirmed to be the highest. Cooling energy consumption in all four climate zones increased as WWR increased due to increase in amount of solar gain. Lighting energy consumption in all four climate zones decreased as WWR increased, with G5 showing smaller consumption than G1 due to VLT’s influence. Climate zone with the amount of energy savings on account of power generation being largest turned out to be San Francisco. Especially, possibility of zero energy building achievement in case of G1, G2 window being applied when WWR was 80% was confirmed. With the result of this particular research, to expand applicability as building exterior materials, products improved upon traits such as colour, insulation, and strength should be under continuous performance evaluation study across various foreign and domestic climate zones.

목적: 보존적 방법으로 조절되지 않는 산과적 출혈의 처치에 있어 본원에서 2년간의 정맥 색전술의 적용실례, 효과 및 합병증에 대해 알아보기 위해 시행했다. 방법: 2006년 1월 1일부터 2008년 12월 31일까지 순천향대학교 천안병원 산부인과학교실에 내원하여 내과적인 방법과 보존적인 지혈방법으로 지혈이 이루어지지 않아 동맥색전술을 받은 25명의 환자를 대상으로 했다. 결과: 적응증으로는 자궁이완증 10예, 제왕절개 시 근종절제수술을 함께 받았던 경우가 6예, 비정상적인 태반 이상의 경우가 5예, 동-정맥 기형이 3예, 자궁경부 임신의 경우가 1예였다. 전체 성공률은 25명 중 22명으로 88%였다. 평균 수혈량은 환자 1인 당 7.2 unit이었고, 색전술에 소요된 시간은 평균 55분이며, 평균 재원일수는 5.5일이었다. 성공한 22명에서 모두 정상적으로 생리가 돌아왔다. 합병증은 시술 후 한 명에서 우측하지 감각이상을 호소했고, 다른 한 명에서 생리량 감소가 있었다. 결론: 본 연구에서 보존적 치료에 실패한 산과적 출혈 환자에 있어서 색전술은 대량실혈을 방지하면서 자궁을 보존할 수 있는 비교적 안전하면서도 효과가 뛰어난 이상적인 방법임을 보여주고 있다. Purpose: The objective of this study was to evaluate the indications, effectiveness and complications associated with uterine arterial embolization as an alternative treatment of obstetrical hemorrhage. Methods: From January 2006 to December 2008, 25 patients who underwent angiographic embolization for the obstetrical hemorrhage that was not responsive to conventional treatments, like obstetric maneuvers and uterotonic drugs, were included in our study. All medical records were reviewed and detailed clinical data such as clinical status, underlying conditions, amount of transfusion, embolized arteries, hospital stay, the success rate and the complications were collected. Results: We have experienced clinically successful embolization in 22 (88%) of 25 patients with obstetrical hemorrhage resulting from various causes. After embolization, the patients` vital signs were stabilized. The causes of hemorrhage were atony of uterus (n=10), myomectomy during cesarean section (n=6), abnormal placentation (n=5), arterio-venous malformation (n=3), and cervical pregnancy (n=1). The average amount of blood transfusion was 7.2 units (range; 0~39 units). The average length of the time for the procedure was 55 minutes (range: 25~96 minutes). The average duration of hospitalization was 5.5 days (range: 2~14 days). In 22 patients, menses resumed spontaneously after procedures. The main complications after embolization were numbness and pain on lower extremities (n=1), and hypomenorrhea (n=1). Conclusion: The atrerial embolization is one of the safe and effective procedures that offers patients an alternative to hysterectomy for the treatment of intractable postpartum hemorrhage.

박보라,김영연 한국음악교육공학회 2018 음악교육공학 Vol.- No.34

The purpose of this study was to examine differences and relationships of the daycare teachers’ perception on music pedagogical content knowledge and music teaching efficacy so as to provide materials for teacher training program revision. The subjects were 212 nursery teachers in B city. Collected data were statistically processed using PASW 19.0, and the results of this study are as follows. First, teachers' perceptions on music pedagogical content knowledge of curriculum knowledge were higher than those of curriculum contents, teaching and learning method, and learners while the teachers' perceptions about music teaching efficacy turned out to be higher in results expectation than in the beliefs in the process of music teaching. Second, the differences in the background variables showed significant difference only in the teacher’s academic background both in the music pedagogical content knowledge and music teaching efficacy. Finally relationship was found between teacher’s perception of music pedagogical content knowledge and of music teaching efficacy. These results strongly suggest that individual teacher educational attainment may be helpful for one’s teaching ability development and there are needs of teacher training program revision with concern on music pedagogical content knowledge and music teaching efficacy. 본 연구의 목적은 음악교수내용지식과 음악교수효능감에 대한 보육교사의 인식의 정도와 차이 및 관계를 알아보는 것이다. 이를 위해 B도시에 근무하는 보육교사 212명을 대상으로 설문조사하였고 수집된 자료를 PASW 19.0로 통계 처리하였다. 연구 결과 첫째, 음악교수내용지식과 음악교수효능감에 대한 보육교사의 인식의 정도는 보통의 수준이었고 하위요소별로는 교육내용, 교수학습·방법, 교육과정(누리과정) 및 학습자(유아)에 대한 이해로 구성되는 음악교수내용지식 증 음악교수내용이나 교수·학습법에 비해 누리과정에 대한 이해가 더 높게 나타났다. 음악교수효능감에 대해서는 음악교수 결과기대를 음악교수 신념 보다 더 높게 인식하는 것으로 나타났다. 둘째, 각각의 하위요소 간의 차이를 보육교사의 배경변인별로 살펴본 결과 음악교수내용지식과 음악교수효능감 모두가 학력에서만 인식의 유의미한 차이가 있는 것으로 나타났다. 셋째, 음악교수내용지식과 음악교수효능감은 모든 하위요소 간에 통계적으로 유의미한 정적 상관관계가 있는 것으로 나타났다. 이상의 결과는 보육교사에게 음악교육내용지식에 대한 이해와 음악교수효능감의 증진 모두가 영유아음악교육의 활성화에 필요한 기반으로서 이를 기초로 유아음악 교사교육이 실시되어야 할 필요성을 시사한다.

통행거리에 따른 유류비를 반영한 경로선택모형 개발

박보라(Park Bora),이재영(Lee Jaeyoung),최기주(Choi Keechoo),송필용(Song Pilyong) 대한토목학회 2010 대한토목학회논문집 D Vol.30 No.6D

본 연구는 거리에 따른 유류비를 고려하여 시간가치를 산정하고, SP 조사를 통해 경로선택 시 통행시간, 통행요금과 함께 거리에 대한 유류비를 반영함이 타당한지 분석하는 것을 목적으로 하였다. 수준 차이를 고려한 SP 조사설계기법을 이용하여 SP 자료를 구축하여 분석하였으며, 통행시간, 통행요금 및 유류비에 대한 가치를 추정하기 위한 모형식을 구축하였다. 모형 추정 결과, 경로선택 시 통행요금과 함께 유류비 역시 운전자의 경로선택에 영향을 미치는 것으로 나타났다. 경로선택에 있어 통행요금이 유류비에 비해 더 큰 것으로 나타났는데, 이는 통행요금이 현금지불경비(out-of-pocket expenses)인 반면 유류비 지출은 주기적이라는 특성 때문에 유류비가 통행요금에 비해 덜 민감하게 나타난 것으로 보인다. In this study, the value of travel time was estimated with reflecting the fuel cost according to travel distance. The main objective of this study is whether the addition of the fuel cost as a factor for route choice behavior is appropriate or not, through the stated preference survey. The route choice model was developed using SP survey technique with the consideration of level difference and the value of travel time, toll and fuel costs. Consequently, the fuel cost is identified as a main factor like travel time and toll cost in choosing routes from drivers' viewpoints. Nevertheless, since toll costs are recognized as out-of-pocket expenses whereas fuel costs as periodical expenses, it seems drivers are more sensitive to toll than fuel costs.
