Objectives : In this study, we researched the change of 'quality of life(QOL)' of patient with panic disorder by KvSBQOL and the predictors affecting the change of 'quality of life'. Methods : 30 outpatient with panic disorder were tested by questionnare for panic disorder and KvSBQOL. Frst, they were classified as when healthy before panic episodes(a point of time 1), when first diagnosed as panic disorder in the psychiatry(a point of time 2), and when treated after diagnosis(a point of time 3). Second, the change of QOL scores in five factors at each point was observed, Third, the correlation between the change of QOL scores(point 3 score-point 2 score) and the several predictors(Onset age, Degree of change in panic symtom, Degree of change in anticipatory anxiety, Degree of change in agraphobia, Spended time to diagnose panic disorder, Duration of treatment) were studied. Results : 1) QOL mean scores of a point of time 1,2 and 3 were 166.267±38.24, 94.367±34.00, 161.367±34.37, respectively. 2) The change of QOL scores in all five factors of KvSBQOL(factor1 Competence, factor2 Psychological well-being, factor3 Stability, factor4 Physical well-being, factor5 Activity)at each point was significant(P<.000). 3) The change of QOL mean scores(point 3 score-point 2 score) have significantly negative correlation with the change of score in anticipatory anxiety but not other predictors. Conclusions : Difference in QOL scores between a point of time 1 and 3 is 4.9, indicating that the psychiatric treatment is important in improvement of QOL, the anticipatory anxiety is an important predictor of QOL(P<.001). and it suggested that diminished anticipatory anxiety is very important to maintain of high QOL in patient with panic disorder.

본 연구에서는 CO2를 이용한 알칼리폐수의 중화처리 시 jet loop reactor의 적용가능성을 검토하고자 하였다. 이를 위해 연속식 jet loop reactor에서 pH=10.1인 알칼리 폐수의 유입유량(QL,in=0.9~6.6 L/min)과 유입가스유량(QG,in=1~6 L/min)을 변화시키면서 유출수의 pH 변화 및 CO2 제거특성을 살펴보았다. 중화반응 후 유출수의 pH는 QL,in/QG,in 비가 1.1일 때는 QG,in 및 QL,in이 증가하여도 pH가 7.2 정도로 일정하게 유지되었다. 그러나 QL,in/QG,in 비가 1.1 이상에서는 QL,in/QG,in 비가 증가할수록 CO2 제거효율 및 배출수의 pH가 증가하는 경향을 보였다. 본 연구범위에서 얻어진 최대 CO2 제거효율은 98.06%로 QG,in=2 L/min, QL,in=4 L/min인 조건이었으며, 이때의 유출수 pH는 8.43 이었다. This paper investigates the feasibility of applying the jet loop reactor for the neutralization of alkaline wastewater using carbon dioxide (CO2). In this study, pH changes and CO2 removal characteristics were examined by changing influent flow rate of alkaline wastewater (initial pH=10.1) and influent CO2 flow rates. Influent flow rates of alkaline wastewater (QL,in) ranged between 0.9 and 6.6 L/min, and inlet gas flow rate (QG,in) of 1 and 6 L/min in a lab-scale continuous flow jet loop reactor. The outlet pH of wastewater was maintained at 7.2 when the ratio (QL,in/QG,in) of QL,in and QG,in was 1.1. However, the CO2 removal efficiency and the outlet pH of wastewater were increased when QL,in/QG,in ratio was higher than 1.1. Throughout the experiments, the maximum CO2 removal efficiency and the outlet pH of wastewater were 98.06% and 8.43 at the condition when QG,in and QL,in were 2 L/min and 4 L/min, respectively.

As the number of defects in apartments has increased recently, lawsuits and disputes related to defects have also increased. As a result, the loss of time and money is enormous. Therefore, fundamental measures are needed to reduce the occurrence of defects. Therefore, the purpose of this study is to propose a plan to reduce defects, focusing on window construction. To this end, existing studies were reviewed, and data from domestic construction companies were collected and classified to organize the types of defects. Based on the classified data, eight types with a high incidence of window glass were analyzed according to the time of occurrence, and the cause and causal relationship of the defect were schematized. It aims to identify the degree of possibility of recurrence of defects for each of the eight defect types for experts and derive key management elements using the RII method. Therefore, the goal is to select key management elements of window construction that actively reflect the characteristics of the construction stage.

목적: 대장 게실 질환은 서양에서는 발생빈도가 매우 높으며 주로 좌측 대장에서 호발하는 것으로 알려져 있다. 이에 비해 동양에서는 상대적으로 발생 빈도가 비교적 드문 질환으로 알려져 왔으나 최근 그 빈도가 증가하는 추세이다. 그러나 국내의 대장 게실염에 대한 연구는 대부분 수술환자를 대상으로 하였다. 이에 저자들은 대장 게실염의 호발부위를 조사하고 우측 및 좌측 대장 게실염의 임상양상을 비교하고자 하였다. 방법: 1998년 7월부터 2006년 12월까지 경북대학교병원에서 임상증상, 복부 전산화 단층촬영으로 대장 게실염으로 처음 진단받고 이후 수술 소견, 대장조영술, 대장내시경 등으로 게실이 확인되었던 환자를 대상으로 의무기록을 후향적으로 검토하였다. 결과: 총 37명(남:여=18:19, 연령 21~75세, 중앙 연령 45세)에서 대장 게실염으로 진단되었다. 게실염 37명 중 30명(81.1%)이 우측 대장에 발생하였고, 남녀 비는 16:14, 중앙 연령은 38.5세였다. 우측과 좌측 대장 게실염 중 중앙 연령이 좌측 대장 게실염 환자에서 통계적으로 의미있게 많았으며(p=0.005), 천공을 동반하는 경우(p=0.001) 그리고 보존적 치료보다 수술적 치료를 시행한 경우(p=0.009)가 좌측 대장 게실염 환자에서 통계적으로 유의하게 높았다. 나머지 임상 양상 및 합병증, 성별, 증상기간, 재원기간 등에 두 군간의 유의한 차이는 없었다. 결론: 본 연구에서 좌측 대장 게실염은 우측 대장 게실염에 비해 발생빈도가 낮지만 비교적 고령에서 호발하고, 천공 등의 합병증을 동반하는 경우가 많아 예후가 불량할 것으로 생각된다. Background/Aims: Left colonic diverticulitis is relatively common in western nations. Although the incidence of colonic diverticulitis is increasing in Korea, very little is known regarding its clinical characteristics in korean patients. Methods: We compared the clinical characteristics of right versus left colonic diverticulitis via the retrospective review of 37 cases treated at the Kyungpook National University Hospital, Korea, from July 1998 to December 2006. Diagnosis was confirmed via computed tomography (CT), barium study, colonoscopy, and/or surgery. Results: Eighteen men and 19 women (median age, 45.0 years; range, 21~75 years) were included. The ratio of right to left colonic diverticulitis was 30:7. The male to female ratio for right colonic diverticulitis was 16:14 and the median age was 38.5 years (range, 21~72 years). The male to female ratio for left colonic diverticulitis was 2:5 and the mean age was 57.0 years (range, 45~75 years). Left colonic diverticulitis was more frequently associated with intestinal perforation (p=0.001) and old age (p=0.005). Surgical intervention was more common in left versus right colonic diverticulitis (p=0.009). Conclusions: These results indicate that although left colonic diverticulitis is relatively rare among koreans, it develops later in life and is more frequently complicated than right colonic diverticulitis.
