In the PEMFC fuel cell system, proper humidity control is a major factor for maintaining the performance and durability of the cell. Therefore, a separate humidifier for humidity control is required, and a shell-and-tubes humidifier using hollow fiber membranes is mainly adopted. Water permeation of hollow fiber membranes is affected by various factors such as temperature or humidity, flow characteristics and surface area. Understanding the moisture transfer characteristics of membrane humidifiers is essential for humidity control. In this study, an Ansys Fluent® computational model was developed to understand the water vapor transfer of membranes. The water transfer was predicted from the concentration difference at both ends of the membrane, and the reliability of the analysis was secured through the experimental results and validation. The vapor transfer according to the number of membranes, air flow rate and relative humidity was discussed through the mass fraction and velocity characteristics around the membrane. 양성자 교환막 연료전지(PEMFC: proton exchange membrane fuel cell) 시스템에서 적절한 습도 제어는 전지의 성능과 내구성을 유지하기 위한 주요 인자이다. 따라서 습도 제어를 위한 별도의 가습장치를 필요로 하며, 중공사형 막을 이용한 원통 다관형 가습기가 주로 사용된다. 중공사 막의 수분 투과는 온습도, 유동 특성 및 표면적 등 다양한 인자에 영향을 받는다. 적절한 습도 제어를 위해서는 막 가습기의 수분 투과 특성 이해가 필수적이다. 본 연구에서는 막의 수분 투과 특성을 이해하기 위한 Ansys Fluent® 전산해석 모델을 개발하였다. 막의 양단의 농도차부터 수분 투과를 예측하고, 실험 결과와 검증을 통해 해석의 신뢰도를 확보하였다. 막의 개수, 공기의 유량 및 상대습도 조건에 따른 수분 전달을 막 주위의 질량분율과 속도 특성을 통해 논의하였다.

Objectives We investigated the tolerability, safety, and treatment response to flexible-dose paliperidone ER in patients with non-acute schizophrenia in whom previous antipsychotic drugs were ineffective. Methods This 24-week interim analysis of the 48-week multicenter, prospective, open-label study assessed effectiveness using the Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression-Schizophrenia-Severity (CGI-SCH-S) Scale, Personal and Social Performance (PSP) and Drug Attitude Inventory (DAI). Safety and tolerability were assessed using the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS) and Liverpool University Neuroleptic Side Effect Rating Scale (LUNSERS). Results Effectiveness was assessed in 169 patients. Significant improvement in the PANSS total score was observed by week-1 and continued until week-24. The response rate was 33%. The CGI-SCH-S and PSP total scores significantly improved during 24 weeks ; however, no change occurred in the total DAI. Fifty-nine percent of patients reported adverse events, of which extrapyramidal symptoms were the most frequent (19.0%). The DIEPSS and LUNSERS scores were improved after 24 week. Conclusions Switching to the flexible-dose paliperidone ER from an ineffective antipsychotic drug was safe, tolerable, and showed a good treatment response in Korean patients with schizophrenia.

최유라,김미경 대한건축학회 2020 대한건축학회논문집 Vol.36 No.5

As there are the elderly who have difficulty in evacuating themselves, it is necessary to develop architectural and institutional planning fornursing homes that can minimize disaster damage. The purpose of this study was to suggest the improvement plan by grasping the currentstatus of nursing homes on planning aspects such as floor plan type, spatial layout, and evacuation route through 14 case studies in Cheongjucity in terms of disaster safety. The results of this study were as follows; the most common plan type was the grouped-corridor typedifficulty in securing evacuation routes. The circulation corridor type is need to be considered because it is possible not only to secureevacuation and nursing routes, but also to create a hanging around corridor for the elderly with dementia. Second, if there is a risk offlooding due to the location, the living room should be placed on the 2nd floor or more. In particular, a kitchen should be placed notadjacent to the entrance and the vertical evacuation route. Third, the horizontal evacuation route should be arranged differently depending onthe floor plan type. For vertical evacuation routes, it is necessary to install outdoor stairs or ramps considering the evacuation characteristicsof the elderly. In addition, the institutional aspects should be considered to ensure the safety of disasters. 본 연구는 충청북도 청주시에 위치한 노인요양시설 사례조사를 통해 재난안전성 확보를 위한 계획적 측면의 현황과 개선방안을 제시하는 것을 목적으로 하였다. 주요 결론으로, 첫째, 그룹형은 대피경로 확보가 어렵고, 중복도 및 편복도형은 대피동선과 간호동선이 길며 병목형상 발생이 우려되는 형태로 지양하고 순환형은 대피 및 간호동선 확보가 가능하고 배회공간 형성으로 이를 고려한다, 둘째, 주요공간 중 생활공간은 입지 상 침수위험이 있는 경우, 2층 이상에 배치하고, 직원공간 및 대피경로와 근접배치하는 것이 필요하다.

엇갈린 교합을 가진 가철성 국소의치에서는 하중시 의치의 다양한 움직임과 불리한 안정으로 인해 환자의 만족감을 얻는 것이 어렵다. 편측 소수 잔존치 증례에서는 안정적인 양측성 지지를 확보하기 위해 임플란트 식립 또는 잔존치근을 이용한 추가적인 치료가 필요하다. 그러나, 본 증례에서는 고혈압, 협심증, 고령 등의 전신질환을 고려하여 가철성 국소의치를 치료방법으로 선택하였다. 엇갈린 교합으로 인해 수직고경이 상실된 환자에게 수직고경을 회복해 주기 위해서 정확한 진단과 분석이 필수적이며, 근신경계에 대한 적응을 파악해야만 수직고경을 회복해 줄 수 있다. In removable partial denture with crossed occlusion, it is difficult to meet the satisfaction of patient due to variable movement of denture and unfavorable stability under loading. In a case with few unilaterally teeth remaining, additional treatments such as implantation or residual root are required to assure bilaterally stable support. However, due to the medical condition of the patient with hypertension, angina and old age etc., removable partial denture was planned as treatment in this case. Proper diagnosis, accurate analysis and full understanding of the adaptation for neuromuscular system are necessary to recover the vertical dimension of patient from a decreased vertical dimension due to crossed occlusion.

용도지역별 폭우재해 취약지역의 재해예방형 도시계획 수립방안: 창원시를 중심으로

최유라,한우석 국토연구원 2024 국토연구 Vol.120 No.-

폭우재해와 같은 기후변화 재난의 유형과 피해 양상이 다양화·복합화되면서 도시 계획단계부터 재해예방형 도시계획의 필요성이 중요해지고 있다. 최근 도시·군기본계획 수립지침상에 방재계획 수립이 강조되고 있으나, 재해예방형 도시계획에 대한 구체적인기준은 부족한 실정이다. 이에 본 연구는 용도지역의특성에 따른 폭우재해 고려 사항과 재해예방형 도시계획 요소를 고찰하고, 이를 기반으로 폭우 재해예방형도시계획 수립방안을 제안하는 것을 목적으로 한다. 연구 결과, 사례지역인 창원시는 토지이용 측면에서지형적 취약성에 의한 피해를 저감하기 위한 방재시설이 적용되어 있었고, 기반시설 측면에서 불투수면, 지하도로 등의 침수피해 가중원인을 파악할 수 있었으며, 건축물 측면에서 용도지역별 다른 재해예방 대책이 적용되어야 함을 파악하였다. 이는 용도지역별로 각기 다른 대책을 강화된 기준을 적용해야 함을시사한다. As the types and damage patterns of climate change disasters such as heavy rainfall disasters become more diverse and complex, urban planning that takes disaster prevention into consideration becomes more important. Recently, the establishment of a disaster prevention plan has been emphasized in ‘Urban or -gun master plans’, but there is a lack of specific standards for urban planning that considers disaster prevention. Accordingly, the purpose of this study is to propose establishing a method for urban planning that considers the prevention of heavy rainfall disasters based on a review of heavy rainfall disaster considerations and the elements of urban planning to prevent disasters based on the characteristics of the use area. As a result of this study, Changwon City, the case study area, applied disaster prevention facilities to reduce the damage caused by topographical vulnerabilities, and identified the main causes of aggravated flooding damage as being impervious areas and underground roads in terms of infrastructure. Furthermore, this study found that different disaster prevention measures should be applied for each use area in terms of buildings. This suggests that strengthened standards should be applied to different measures for each use area.

최유임(Choi, Yoo-Im),김원호(Kim, Won-Ho),박은영(Park, Eun-Young),김은주(Kim, Eun-Joo) 한국산학기술학회 2012 한국산학기술학회논문지 Vol.13 No.9

이 연구는 뇌졸중 환자를 대상으로 한국판 수정바델지수(Korean Version of Modified Barthel Index: K-MBI) 의 타당도, 신뢰도와 문항변별도를 알아보기 위해 실시되었다. 223명의 뇌졸중 환자를 대상으로 K-MBI를 사용하여 일상생활활동을 측정하였다. 타당도를 알아보기 위해 요인분석을 실시하였고, 문항내적 합치도, 문항변별도를 알아보 았다. 요인분석 결과, K-MBI의 10개 항목의 공통성은 .50이상으로 나타났으며, 하나의 요인에 적재되는 것으로 나타 났다. 설명량은 72.184%이었다. 요인적재량은 용변처리, 개인위생, 의자/침대 이동, 보행/의자차, 옷 입기, 식사하기, 대변조절, 목욕하기, 소변조절, 계단 오르기 순으로 나타났다. K-MBI의 Cronbach α 값은 .944로 나타났으며, 각 항 목의 문항변별도는 .783~.909로 만족할 만한 수준이었다. 요인분석을 통해 K-MBI의 일상생활활동이라는 하나의 구 성요인을 확인하였으며, 신뢰도와 문항변별도를 확인하였다. 뇌졸중 환자의 일상생활활동의 타당한 평가를 위해, 앞 으로의 연구에서는 K-MBI의 다양한 심리측정학적 특성을 알아보는 연구가 필요할 것으로 생각된다. The purpose of this study was to identify the validity, reliability, and discriminative index of the Korean version of Modified Barthel Index (K-MBI). For this, two hundreds twenty-thee stroke patients participated. Activities of daily living were measured through using K-MBI. Factor analysis was performed for identifying the construct validity and internal consistent and discriminative index were calculated. The result of factor analysis was that the 10 items of K-MBI have communality above .50, and was constructed one factor. Explained variance was 72.184%. The order of factor loading value was toileting, personal hygiene, transfer from bed to chair and back, ambulation/wheelchair, dressing, feeding, bowel control, bathing, bladder control, and stair climbing. Cronbach α of K-MBI was .994. The range of discriminative index was .783~.909, and was acceptable. One factor of K-MBI was identified through factor analysis, and reliability and discriminative index was also identified. Various psychometric properties of K-MBI should be investigated in further studies for valid assessment of activities of daily living in stroke patients.
