Objectives Physical activity is known to be beneficial to prevent weight gain and to be physically healthy. In this study, we tried to find out the relationship between body composition with physical activity. Methods International Physical Activity Questionnaire(IPAQ)-short form was given to premenopausal women aged 20~55 and BMI≥23 kg/m2. Subcutaneous and visceral adipose tissue of the subjects by CT scanning was obtainedin a single slice. They were given written consent and this study is performed under the permission of institutional review board of Kyung Hee East-west Neo Medical Center. Results The mean of physical activity of total subjects was 1935.18 MET-min/week(n=63). When three groups of physical activity pattern(inactive, minimally active, and HEPA(Health-enhancing physical activity) active) was analyzed, all of them were heavily relied on the activity intensities of walking. The VSR(visceral/Subcutaneous adipose tissue Ratio) was correlated with total physical activity in vigorous activity group. Conclusions The physical activity of Korean obese and overweight women was on the average, but the vigorous activity is thought to be necessary. The vigorous physical activity was related with visceral adipose tissue.

Acrylate 수계 결합제를 사용한 알루미나 테이프 캐스팅용 슬러리의 완전분산을 위한 최적의 분산제와 분산제량을 결정하기 위해 침강실험, 분말 함유량 실험, 점도 및 zeta 전위 측정을 행하였다. 알루미나 슬러리의 완전분산은 분산제를 polycarboxylic acid로 했을 때 얻어졌으며, 최적의 첨가량은 알루미나 100에 대하여 0.23∼0.24g 이었다. 분말에 대한 분산제량이 증가할수록 분산은 잘 이루어졌으나, 일정량 이상이 첨가되면 분산제가 용매 안에 과잉으로 존재하여 분산을 저해하는 요인으로 작용하였다. 테이프 캐스팅용 슬러리는 100g의 알루미나 분말에 0.2g의 polycarboxylic acid를 첨가하였을 때 분산 및 테이프 특성이 가장 우수하였고, 이 때 혼합한 결합제는 acrylate였고, 가소제는 Benzoflex를 사용하였다. 이 때 슬러리 최적 점도는 약 570 cps였고, 테이프 내 알루미나 량은 57 vol%이었다. Measurements of sedimentation, solid loading, zeta potential, and viscosity were employed to determine a proper dispersant and its amount for a well dispersed alumina powders in aqueous alumina tape casting using acrylate as a binder. Polycarboxylic acid was the most effective one among various dispersants considered in the present study and its amount was 0.23∼0.24 g per 100 g alumina for a dispersion. Better dispersion was obtained as an increase of dispersant addition. However, the dispersion was hindered as the amount of dispersant was higher than the optimum amount because of bridging or tangling of polymer chains. Excellent aqueous alumina tapes were prepared from the slurry containing the optimum amount of the polycarboxylic acid (0.2g), alumina powders(100 g), acrylate and Benzoflex as binder and plasticizer, respectively. The viscosity of the slurry was 570 cps and the alumina loading in the tape was 57 vol%.

Objectives The aim of the study was to investigate the relationship between oriental obesity pattern, life habitual factors(eating attitude,physical activity) and psychological factors(depression, stress, self-esteem) in korean obese and overweight women. Methods This study was performed in obese and overweight(BMI ≥ 23 kg/m2) women in Korea (n=56). Simple anthropometry including weight,BMI, waist circumference, BIA(bioelectrical impedance analysis) were done. To assess psychological factors, the Rosenberg self-esteem scale (SES) questionnaire, Beck depression inventory (BDI) questionnaire and stress response inventory (SRI) questionnaire were administered. Regarding diet, Korean eating attitude test(KEAT-26) was done. International physical activity questionnaire(IPAQ) was administered for exercise and physical activity intensity and quantities. All values were verified using correlation analysis. Results 1. The subjects had stagnation of the liver qi>food accumulation>yang deficiency>blood stasis>spleen vacuity in the order. 2. Stagnation of the liver qi score had significant relationships with self-esteem(r=-0.520, p<0.05) and depression(r=0.688, p<0.01) in stagnation of the liver qi group. There was a relationship between food accumulation score and eating attitude(r=0.784, p<0.01)in food accumulation group. 3. Lean mass had a significant relationship with self-esteem(r=0.434, p<0.05) fat mass had a significant relationship with stress (r=0.633, p<0.01) and in stagnation of the liver qi group. 4. Physical activity had significant relationships with lean mass(r=0.628, p<0.01) and with fat mass(r=-0.478, p<0.05) in group. Conclusions This study maintained that psychological factors play major roles in obesity with symptoms of stagnation of the liver qi and life habit(dietary factors and physical activity) in food accumulation.

1. $^{60}Co$의 $\gamma$선 128 rad로 마우스를 전신조사시킨 바 대조군과 cortisone투여군에서 총 혈청단백량은 1일구에서 A/G비는 5일구에서 각각 증가의 정점을 나타냈고 이후 정상치로 되돌아가는 경향을 나타냈다. 2. cortisone acetate는 전신조사후 총혈청단백량에 있어서 5, 10 및 20일구에서 증가의 지체성을 나타냈다. 3. cortisone acetate를 전신조사후 A/G비에 있어서 1, 5 및 10일구에서 증가의 지체성을 나타냈다. 4. 이상의 결과로 미루어 보아 전신조사전 cortisone 처리는 혈청단백질의 방사선 감수성을 감소시킴을 알수 있으므로 방사선 방어효과가 있다고 사료된다. Male mice of strain SM were given 128 rads of single whole-body gamma-irradiation of $^{60}Co$, 14 to 16 minutes following a subcutaneous injection of physiological saline or cortisone acetate (1mg/day, for 4 days preirradiation). The serum protein patterns and the level of the total serum proteins were determined at various time intervals after exposure. Total serum protein was determined by Biuret method and serum protein fractions and A/G ratio were determined by paper electrophoresis using Whatman No.1 filter paper and barbital buffer (pH 8.6, ionic strength 0.06). 1. Total body gamma-irradiation caused a rise in the level of the total serum protein at 1 day and in the level of the serum albumin-globulin ratio at 5 days in both cortisone acetate-treated and control groups. 2. Cortisone acetate delayed the total serum protein rise at 5, 10, and 20 days after exposure. 3. Cortisone acetate delayed the A/G ratio rise at 1, 5, and 10 days after exposure. 4. It may be inferred that cortisone greatly reduces the sensitivity of mice to gamma-irradiation on the blood protein, probided that cortisone is given before the exposure.

혐오ㆍ기피 도시자원의 활용에 관한 사례연구

조유정,이형석,김도년 한국도시설계학회 2015 도시설계 : 한국도시설계학회지 Vol.16 No.3

Overtime, industrialization in cities caused environmental degradation and landfills, abandoned industrial facilities and neglected waste. Solving this environmental and social dilemma and restoring the environment is therefore the most pressing issue currently facing the city. In order to accomplish restoration in the cities, it is necessary to overcome our negative perception of hazardous sites, abandoned industrial facilities and waste sites, and to instead see them as potential resources for the city. The purpose of this study is to recommend practical reutilization of municipal waste sites and other negative by-products leftover from industrialization. Following case studies such as utilization of contaminated sites and landfills, utilization of industrial waste facilities were classified and examined. The cities from the selected case studies show that recycling urban resources creates added value for the city’s composition and management, and also forms a basis for converting negative perception of the site into positive perception. The environmental and geographic conditions of cities reviewed in overseas case studies can be different from cities in the Republic of Korea. However, it is nonetheless worthwhile to benchmark by adjusting the conditions to fit Korean standards. 산업혁명 이후 도시의 산업화는 도시의 발전과 경제적 성장을 동반하였으나 환경적ㆍ사회적지속성의 가치가 상대적으로 희생 또는 간과되어 여러 문제와 부작용을 양산해 왔다. 현재 도시가 당면한 가장 시급한 문제로서 그동안의 산업화로 인하여 훼손된 환경과 매립지, 폐산업시설과폐기물의 방치로 인한 환경적ㆍ사회적 갈등 문제를 해결하고 환경의 회복을 위한 노력이 필요하다. 이를 위해서는 혐오ㆍ기피대상으로 인식했던 오염부지, 폐산업시설, 폐기물 등을 도시의 자원으로 바라보는 인식의 전환이 필요하다. 본 연구의 목적은 산업화로 인한 부산물 및 도시 폐기물의 활용방향을 도출하는 것이다. 이에 사례연구로서 오염부지/매립지를 활용한 사례와 폐산업시설을 활용한 사례, 도시 고형폐기물을 활용한 사례로 분류하여 조사하였다. 각 사례는 도시자원으로서 기존의 한계점, 도시자원으로 활용 방향, 활용을 위한 적용 수단, 활용 후 부가가치에대해 분석하였다. 선정된 사례의 도시에서는 혐오ㆍ기피대상으로 인식했던 도시자원을 재활용함으로써 도시를 조성하고 관리함에 있어 부가가치를 창출하고 있으며, 인식의 전환이 그 기반이되었다. 해외 사례에서 나타나는 도시의 환경적ㆍ지역적 여건은 우리나라 도시와 다를 수 있으나우리나라의 여건에 맞게 벤치마크 할 필요가 있다.

Billroth II 위-공장 문합술을 시행한 환자에서 내시경을 이용하여 치료한 ERCP 관련 천공 1예

조유정,송태준,장한얼,이혁,배원기,김남훈,김경아,이준성 대한췌담도학회 2013 대한췌담도학회지 Vol.18 No.3

Endoscopic retrograde cholangiopancreatography (ERCP) has become widely available for the diagnosis and treatment of various pancreaticobiliary diseases. ERCP is a relatively safe endoscopic procedure, however, there is the potential severe, life-threatening complications including pancreatitis, hemorrhage and perforation. ERCP-related perforation, which has been reported as 0.3 to 0.6%, are a rare but serious complication. The management of ERCP-related perforations has been controversial, but the diagnosis of perforations remote from the papilla may be frequently delayed and typically require surgery. We reported a case of ERCP-related bowel perforation successfully treated by endoscopy using multiple hemoclips 저자들이 경험한 이번 증례는 Billroth II 위-공장 문합 술을 시행 받은 환자에서 ERCP 및 EPBD로 담석 적출 후 발생한 소장 천공에 대해 클립과 파이브린 글루를 이용하 여 성공적으로 내시경적 봉합술을 시행한 증례이다. ERCP 시술 관련 천공의 치료는 조기 진단이 무엇보다 중요하며 적절한 치료방범의 선택이 필수적이다. 따라서 ERCP 시행 후 임상증상의 변화가 나타난다면 주의 깊은 추적 관찰이 필요하며 항상 천공의 가능성을 염두에 두어야 한다. 이번 증례와 같이 내시경적 치료를 통해 수술 없이 빠른 회복을 기대해 볼 수도 있는데 이를 위해서는 대상 환자의 적절한 선택과 함께 클립 및 파이브린 글루를 이용한 내시경적 봉 합술 같은 비수술적 치료 지침에 대해 향후 많은 연구가 필요할 것으로 사료된다.

“Workplace Bullying” Before and After Enforcement of the Revised Labor Standards Act in 2019 Exploration of Changes and Characteristics of Phenomena: Analysis of Media Articles Using The Korea Press Foundation’s BIGKinds from 2017 to 2022

조유정 한국비즈니스학회 2023 비즈니스융복합연구 Vol.8 No.2

This study aims to analyze the changes and characteristics of workplace bullying by examining news articles in the media before and after the implementation of the Labor Standards Act workplace bullying prohibition system, which was enforced in 2019. In particular, big data news analysis was attempted using BIGKinds, the integrated database of news articles from the largest in Korea provided by the Korea Press Foundation. As a result of the analysis, firstly, it was found that from January 1, 2017, to December 31, 2022, there were 1,353 press articles on bullying at work, showing a 6.8-fold increase from 42 in 2017 to 286 in 2022. This highlights the persistent issue of human rights violations in the workplace despite the implementation of the revised Labor Standards Act. Secondly, the increase in media coverage after the implementation of the Workplace Bullying Prevention Act indicates the media's tendency to focus on incidents related to the law. Thirdly, analyzing big data on news articles related to workplace bullying can provide insight into the extent of human rights violations experienced by workers. However, since anyone can be a victim or perpetrator, it forces us to confront the issue of workplace bullying and the distorted nature of our society's organization in regards to human rights. Simply amending the Labor Standards Act is not enough to effectively prevent and address workplace bullying. A victim-centered approach that prioritizes human rights protection is necessary.

Purpose: The purpose of this study was to investigate the effects of self-efficacy and social support on health promotion behaviors of patients with stroke. Methods: A sample of 123 patients with stroke was recruited from outpatient department of a hospital. Data were collected between September and October in 2015 using Health Promoting Lifestyle Profile II (HPLP-II), the Homebound Stroke Patients’ Self-efficacy, and the Multidimensional Scale of Perceived Social Support (MSPSS). Results: The mean score of HPLP-II, self-efficacy, MSPSS were 2.71 out of 4, 63.87 out of 75 and 37.91 out of 60, respectively. Multiple regression analysis demonstrated that self-efficacy and family support explained 40% of the health promotion behaviors among the stroke patients. Conclusion: The results of the study revealed that self-efficacy and family support have significantly positively correlated with health promotion behaviors. These correlates should be taken into account in the development of interventions to support patients with stoke in health behavior change.
