In the sports participation by sex. (men 57%, women 30.5%) showed more active than women, and clerical workers also showed more active than skilled workers (Clerical workers 58.3%, Skilled workers 39.37%) 2. In the place of sports participation men use the 32.9% of facilities in the neighborhood and 27% of tose in the company. It whows that women enjoy sports at home in the rate of 30.5%, and regional facilities in the rate of 24.7%, and it shows that both clerical workers and skilled workers normally regianal facilities. 3. The actual condition that employees play sports activities showed kind of sluggish proportion men normally showed high rate (23.8%) in football, and women high rate (20.7%) in the table tennis. In case of clerical & the skilled workers also showed high rate in table tennis. 4. In there reason for their participation in sports activities, it shows that men and clerical workers play for their health, their joy, therir mental training and it showed that women skilled workers play for their joy, their health, and their moral Culture. 5. The reason for their impossibility of sport participation showed that both of them lack time officially, they are tired and they lack place, and facilities, In the clerical and the skilled workers almost showed the identical rate. 6. In the Satisfaction of sports facilities, and skilled workers. They showed 36.7% & 37.2% respectively in very dissatisfaction 28.2% & 33.6% respectively in dissatisfaction and 11.3% & 49% respectively in satisfaction, on the other hand, incase of women and clerical workers they showed 37.9% & 26.6% respectively in dissatisfaction 37.6% & 28.0% respectively in very dissatisfaction, and 2.4% & 13.4% Respectivelly in satisfaction. 7. In the future, discion of sports participation showed the result that 84.3% in men and 91.5% in women had participated in sports, and in case of the clerical & skilled workers. They showed that 88.8% in the clerical workers and 87.% in the skilled workers had participated in the sports. 8. In the worker place, regarding the request for sports activities we have to illustrate on the who the time consideration the necessities of leaders and sports program. 9.

Hwang, Sung Jin,Oh, Dong Joon,Jung, Phill Gu,Lee, Sang Min,Go, Jeung Sang,Kim, Joon-Ho,Hwang, Kyu-Youn,Ko, Jong Soo IOP 2009 JOURNAL OF MICROMECHANICS AND MICROENGINEERING - Vol.19 No.9

<P>This paper presents a new polydimethylsiloxane (PDMS) dry-etching method that uses microwave plasma. The applicability of the method for fabricating microstructures and removing residual PDMS is also verified. The etch rate of PDMS was dominantly influenced by the gas flux ratio of CF<SUB>4</SUB>/O<SUB>2</SUB> and the microwave power. While the PDMS etch rate increased as the flux ratio of CF<SUB>4</SUB> was increased, the etch rate decreased as the flux ratio of O<SUB>2</SUB> was increased. The maximum etch rate of 4.31 µm min<SUP>−1</SUP> was achieved when mixing oxygen (O<SUB>2</SUB>) and tetrafluoromethane (CF<SUB>4</SUB>) at a 1:2 ratio at 800 W power. The PDMS etch rate almost linearly increased with the microwave power. The ratio of the vertical etch rate to the lateral etch rate was in a range of 1.14–1.64 and varied with the gas fluxes. In consideration of potential applications of the proposed PDMS etching method, array-type PDMS microwells and network-type microprotrusion structures were fabricated. The contact angle was dramatically increased from 104° (non-etched PDMS surface) to 148° (etched PDMS surface) and the surface was thereby modified to be superhydrophobic. In addition, a thin PDMS skin that blocked holes and PDMS residues affixed in nickel microstructures was successively removed.</P>

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

To evaluate the in-vivo effects of mitomycin-C-polyglycolic acid composite(MMC-PGA) the disk: shaped composite were implanted into the peritoneal cavity of the Sprague-Dawley rats. The pathologic changes were examined at various time points up to 12 weeks. Initially the soft tissue around the inserted disks showed capillary congestion at 3 days. Inflammatory infiltrates with foreign body giant cells appeared from the 2nd week and reached peak response at 6-8 weeks. These reaction diminished prominently at 12 weeks. No specific pathologic change was found in the liver, the kidneys, and the heart. The above results suggest that the MMC-PGA composite can serve as a new device for intraperitoneal chemotherapy of various types of cancers.

Background/Aims: The aim of this study was to quantitatively measure changes in lipids and lipoproteins during perimenopause and to identify variables related to these changes. Methods: Among women who had three regular health evaluations over a span of 2-4 years, 34 women remained in the premenopausal state, 34 premenopausal women transitioned to the postmenopausal state, and 36 postmenopausal women were enrolled. The menopausal state was determined not only by a history of amenorrhea but also by levels of female sex hormones. Yearly changes in lipids were calculated using a linear regression of the three measurements. Results: The transition from premenopause to postmenopause was associated with increased total cholesterol and low-density lipoprotein (LDL) cholesterol levels by 7.4 ± 8.0 mg/dL (4.2 ± 4.9%) and 6.9 ± 6.5 mg/dL (6.8 ± 7.0 %) over one year, resulting in an elevation of 19.6 ± 22.6 mg/dL (10.9 ± 13.0%) and 18.9 ± 19.5 mg/dL (18.6 ± 20.3%), respectively, during perimenopause. There were no changes observed in premenopausal and postmenopausal women. Body weight, blood pressure, high-density lipoprotein (HDL) cholesterol, and triglycerides did not change in any of the three groups. In all women, changes in both total cholesterol and LDL cholesterol were associated with changes in follicle stimulating hormone (r = 0.40, p < 0.001 and r = 0.38, p < 0.001, respectively). Changes in triglycerides were associated with changes in body weight (r = 0.28, p = 0.005). Conclusions: During perimenopause, total and LDL cholesterol levels increase and these changes in cholesterol are mainly dependent on changes in female sex hormones.

목적: 대퇴부 전자간 골절의 치료에 있어서 활강 압박 고 나사 (CHS)와 항회전 근위 대퇴 골수정 (PFNA)의 치료 결과를 비교 분석하고자 하였다. 대상 및 방법: 2005년 1월부터 2009년 6월까지 본원에서 동일 술자에 의해 대퇴 전자간 골절로 수술 받은 환자 중 압박 고 나사로 치료한 36예와 항회전 근위 대퇴 골수정으로 치료한 48예를 대상으로 하였다. 두 군 간의 수술 시간, 출혈량, 방사선적 결과를 비교하였으며 임상적 결과는 Parker와 Palmer의 보행 점수와 Jensen의 사회 기능지수를 이용하여 평가하였다. 결과: 평균 수술 시간 및 평균 출혈양이 CHS군에서 116.7분, 486.1 ml, PFNA군에서 87.7분, 289.6 ml로 PFNA군에서 통계학적으로 유의하게 적었다. 방사선적 결과는 두 군 간에 유의한 차이가 없었다. 임상적 결과로 Parker와 Palmer의 보행 점수와 Jensen의 사회 기능지수에서 두 군 간에 유사한 하락을 보였다. 술 후 합병증은 CHS 군에서 지연나사의 근위부 이동 및 대퇴 골두 관통이 2예, 심부 감염이 1예에서 관찰되었다. 결론: 대퇴골 전자부 골절 시 PFNA는 CHS와 비교해 임상적, 방사선학적 결과와 합병증 발생에서 의미 있는 차이는 보이지 않았다. 하지만 PFNA는 CHS군에 비해 덜 침습적인 방법으로 고령의 환자에서 유용할 것으로 생각한다. Purpose: To evaluate the radiologic, clinical results between who had intertrochanteric fracture, treated with Compression Hip Screw (CHS) and Proximal Femoral Nail Antirotation (PFNA). Materials and Methods: We retrospectively reviewed each 36 and 48 patients of intertrochanteric fracture which were treated with CHS or PFNA by one surgeon from January 2005 to June 2009. We evaluated mean operation time, amount of bleeding, radiologic results, and the clinical outcomes with the mobility score of Parker and Palmer, social function scoring system. Results: The mean operation time, amount of bleeding were less in the PFNA group, there were 116.7 min, 486.1 ml for the CHS group versus 87.7 min, 289.6 ml for the PFNA group. The radiologic results were not significantly different. Decrease of mobility score of Parker and Palmer, social function score were similar. Proximal migration of leg screw and perforation of femoral head was 2 case and deep infection was 1 cases in CHS group. Conclusion: There were no significant differences that are clinical and radiological results in treatment of intertrochanteric fracture using the CHS and PFNA. But PFNA is less invasive device than CHS, therefore it may be useful device in elderly patients.

Min Yoo,Hyun Ho Kim,Jeong Ryong Oh,Jeung Ho Kim,Mu Soo Jung 대한인간공학회 2012 대한인간공학회 학술대회논문집 Vol.2012 No.5

Objective: This study is aimed at analyzing the characteristics of Work-related Musculoskeletal disorders (WMSDs) from various prospects based on the industrial accident statistics and field survey. The results can be used to develop more effective policies to prevent WMSDs. Background: Cleaning work is demanding and labor intensive. Many tasks involve heavy manual work, putting strain on the heart, muscles and other tissues. Cleaners are often required to work in awkward postures for long periods and this may lead to long-term damage, but there has been little research results about cleaner's work status and characteristics of WMSDs. Method: (1) We analyzed the various characteristics of WMSDs of cleaners according to industrial accidents statistics in 2009-2011(i.e. age, gender, working duration, risk factors, etc.). (2) Also, we conducted field survey concerning the musculoskeletal discomfort, understanding of WMSDs, musculoskeletal symptoms, etc. at 100 enterprises, 536 cleaners in Gwangju provinces. Results: The majority of patients were over 60 years old(46.2%), female(75.2%), companies with less than 50 workers(83.3%), less than 6 month of working duration(34.8%), and forceful exertions(63.3%). According to Musculoskeletal Burdened Work which was notified by the Minister of Employment and Labor in 2011, high risk task was shown in Task2, Task3, Task4, Task8, and Task9. The musculoskeletal discomfort in accordance with Borg's CR10 scales of main tasks consisted of 5.86 wiping workers, 5.78 mopping workers, 4.74 swiping workers, 2.28 preparing/waste collecting workers. Conclusion: These results showed that there were significant characteristics of WMSDs of cleaners that could be used as basic data for the WMSDs prevention policy.
