This study was carried out to test the body fat breakdown during topical seaweed extract treatment and in combination with the aerobic exercise. Of 20 female obesity subjects, ten treated a cream types of seaweed extract(control group) and ten treated a placebo cream(placebo group). Topical treatment of each sample was designed for 4 weeks, and treated with 2 times a day about 10ml on the abdomen and the thigh, respectively. All subjects were participated aerobic dance half hour a day and four times a week. After 4 weeks of topical treatment and exercise, they were measured body fat, skinfold thickness, body circumference. Then venous blood samples were taken and analyzed blood cells, serum enzymes, and serum lipids. There were reduction of body weight, % of body fat, antebrachium, brachium, chest, waist, thigh circumference and abdomen thickness between pre and post treatment in both group. Especially, body weight and % of body fat significantly reduced in the subjects treating the seaweed extract than those treating the placebo. There were significant decrement in total cholesterol and LDL whereas increment in HDL and TBIL in the control group, but no significant difference in the placebo group. In conclusion, there were 7.6% of body fat reduction during 4 weeks of aerobic exercise and 21% of body fat reducement in combination of topical seaweed treatment and exercise, respectively. These results suggest that the topical treatment of seaweed extract should be very effective for fat breakdown. Especially, the body fat breakdown maximized in the combination with the topical seaweed extracts treatment and the aerobic exercise.

ABSTRACT - This study was performed to evaluate hepatoprotective effect of daewhang-whangryunhaedok-Tang(DWT) on liver injured rats induced by CCI_4 and the acute oral toxicity of it in mice. The activities of serum transaminase(ALT/AST), alkaline phosphatase(ALP) and lactic dehydrogenase(LDH), the levels of serum total cholesterol(TC) and triglyceride(TG), change of liver enlargement, and inhibitory activities of lipid perotidation, catalase and glutathione-S-transfrease(GST) in liver microsome were determined in hepatotoxic rats induced by CCI_4. DWT was significantly reduced the serum ALT, AST, ALP, LDH. TC and TG lecels. And, the increase of lipid peroxidation, decrease of catalase and GST activities in the liver microsome of CCI_4-intoxicated rat were significantly improved by the treatment of DWT. Male and female mice were administered maximum dosages of 5.000 mg/kg b.w. of DWT. After single oral administration of DWT to mice, we observed them daily for 2 weeks.DWT did not induce any toxic signs in the mortalitie, clinical signs, body weight changes, and gross necropsy finfings of mice. Based in these results. It is concluded that DWT may have the hepatoprotective effect on CCI_4 induced hepatotoxicity in rats. Also. DWT may have no side effect and its LD_50 value may be over 5.000mg/kg b.w. in mice.

배경: STS의 발생에 대해서 다양한 원인이 알려져 있으며,손상과 이물질도 그 원인으로 알려져 있으나 그 발생 증례는 매우 드물다. 저자들은 금속단판 절단원에서 지속적인 손상과 금속 이물질로 추정되는 물질과 관련성을 보이는 ES 증례를 경험하였기에 문헌고찰과 함께 보고하고자 한다. 증례: 환자는 17년간 금속단판 절단원으로 근무하였다. 작업 도중 지속적으로 작은 금속파편에 손바닥을 찔렸으며,작업 중에 금속파편이 손에 박혀 있어 퇴근 후에 매일 제거하였다. 2004년 3월에 손바닥에 종괴가 촉지되었으며, 2006년 11월에 수부 X-ray에서 이물질과 종괴가 발견되어 제거하였다. 종괴는 ES로 진단받았으며 환자가 사용했던 모든 금속봉에는 크롬과 니켈이 함유되어 있었다. 결론: 증례와 같은 이물질 및 손상과 관련을 보이는 STS 특히 ES은 매우 드물며,이물질에 의해 자주 노출되고 손상을 받는 근로자에서 육종이 발생했을 때,그 작업관련성을 의심하여 볼 필요성이 있다. Background: Soft tissue sarcoma is a rare condition with many causative factors. However a soft tissue sarcoma from a metallic foreign body and injury is rare. We report a case of a soft tissue sarcoma caused by a metallic foreign body and injury. Case: The patient had been worked as a metal cutter for 17 years. While working, his palms were constantly pricked by small metallic splinters, which were generally removed after work. On march 2004, he had palpitated mass on his right palm. On November 2006, a right hand x-ray showed a mass and metallic foreign body at the 1st volar space which was confirmed to be an epitheloid sarcoma. All metallic products of his workplace contained chromium and Nickel. which are known to cause soft tissue sarcomas. A review of the literature revealed foreign-body and injury induced oxidative and nitrative stress to be associated with a developing sarcoma. In addition, Cr and Ni are associated with the development of sarcoma. Therefore it was concluded this case ofepitheloid sarcoma was associated with his employment. Conclusion: A soft-tissue sarcoma associated with a metal foreign-body and injury is rare and their relationship is difficult understand. If a case of sarcoma is encountered on a metal associated worker, their job association should be considered.

김민기,이원철,이영민,유재홍,김환철,유승원,남경한 大韓産業醫學會 2008 대한직업환경의학회지 Vol.20 No.4

배경 교번제 근무에 의해 지하철 근로자들의 수면의 질은 영향을 받고 있으나 기존 연구자체가 교번제를 행하는 지하철 기관사들만을 대상으로 하여 3교대 근로자 및 비교대 근무자의 수면의 질 점수와 수면장애군 분포의 차이를 비교할 수 없었고 수면에 영향을 끼치는 요인들을 파악할 수 없었다 이에 본 연구는 교번제와 3교대제 및 비 교대제 근로자들 간에 수면의 질의 차이가 있는지와 영향을 끼치는 요인들에 어떤 것들이 있는 지를 분석하기 위해 본 연구를 수행하였다 방법 2007년도 5월 초에 일개 지하철공사에 근무하는 모든 근로자를 대상으로 구조화된 설문지를 배포하였으며 2007년 5월말까지 회수되었다 회수된 설문지 중 수면의 질 평가설문지를 완벽히 기재하지 않은 70(6.93%)명과 그 수가 많지 않은 여성 근로자 36(3.56%)명을 제외한 759(75.15%)명의 남성 지하철근로자를 대상으로 설문분석을 시행하였다 자기기입식 설문지를 통하여 얻어진 자료를 SPSS (ver 12.0)프로그램을 사용하여 분석하였다 결과 교번제 근로자들이 직무요구와 직무불안정을 제외한 모든 직무스트레스점수 영역에서 가장 높은 점수를 차지하고 있으며 한국형직무스트레스 중앙값과의 비교에서도 교번제 근로자 중에서 직무스트레스 하부항목의 평균값 이상의 비율이 높았다 비교대 근무근로자들은 직무요구 직무불안정 항목에서 가장 높은 점수를 나타내었다 교대제에 따른 수면의 질 점수에서도 교번제 근로자들의 평균값이 5.1로 수면의 질 증상 점수인 5점을 넘고 있었으며 교대제에 따라 수면의 질 점수와 증상분포에 차이를 보였다 수면의 질은 직무요구가 높고 외적통제 신념이 강할수록 지난 1년간 아차사고를 경험하였거나 업무 중 사고를 경험하였을 때 나빠지며 비교대제 이거나 내적통제신념이 강할수록 좋아지는 결과를 보였다 결론 교번제에서 수면의 질 평균점수가 가장 높고 증상군의 비율도 가장 높았으며 직무스트레스의 대다수 항목에서 가장 높았다 지하철근로자들의 수면의 질 향상을 위해서는 교번제를 가급적 줄이는 교대제 체계의 개선 및 직무요구의 적절한 분배 내적통제신념 등의 향상과 사고 및 아차사고에 노출되는 교번제와 3교대 근로자들을 위한 사고 예방교육이 도움이 될 수 있을 것이다 Background The sleep quality of subway drivers who work in the dark underground with an rotating shift system is generally poor, which can degrade the quality of a worker's life This study examined the relationship between the sleep quality of subway worker and shift work by comparing three shift systems (rotating shift system, a three day shift system and no shift system). Method Questionnaires including The short form of the Korean Occupational Stress Scale (KOSS) Pittsburgh Sleep Questionnaire (PSQI), the worker's age gender job type, accident, near miss and shift system were given to a total of 1010 workers The results of 759 qualified questionnaires (75.15 %) were analyzed using the SPSS (ver 12.0) program. Result The highest level of job stress was found among those working a rotating shift system followed by three shift system and no-shift system. The mean sleep quality score in the rotating shift workers was 5.1 (SD±3.2), which was greater than the sleep symptom score (5) 34.8% of rotating shift workers suffered from sleep symptoms. The sleep quality score by shift-work was significantly different High job demand, strong external locus control, the experience of a near miss or an accident in the workplace during previous year has an adverse affect on the sleep quality The sleep quality improved in case of a change into a no-shift system or a strong internal locus control. Conclusion A rotating shift system is more harmful to the quality of sleep in subway workers than a 3 shift system or no-shift system. In addition, job stress, personality, near miss and the experience of an accident affect the sleep quality of subway workers.

김재홍,김지환 서강전문대학 2000 산업과학연구 Vol.2 No.-

In this study, the analysis of the dynamics characteristics and performance investigation of the pressure measurement in the hydraulic pipe. the exact solution th the frequency response is obtained by using the complicated transfer function. the discrepancy with the exact and the approximate is small, so the approximation solution is adopted to compare the experimental result whit the theoretical analysis. The pressure measurement in the hydraulic pipe is caused by length of capillary and according to the end volume size. The experimental and calculate result show that characteristic of the pressure measurement in the hydraulic pipe varies with the length of capillary and end volume size. Therefor present theoretical formulation and experimental result can be used generally in designing and performance evaluation of all the hydraulic pressure measurement in the hydraulic pipe
