D. K. LEE, J. S. LEE, B. J. LEE, H. S. LEE, Y. J. KIM, S. B. PARK, J. P. JOO. PIantar foot pressure analysis during golf swing motion using plantar foot pressure measurement system. Korean Journal of Sport Biomechanics, Vol. 15, No. 1, pp. 75-89, 2005. In this study, weight carrying pattern analysis and comparison method of four foot region were suggested. We used three types of club(driver, iron7, pitching wedge). This analysis method can compare between top class golfer and beginner. And the comparison data can be used to correct the swing pose of trainee. If motion analysis system, which can measure the swing speed and instantaneous acceleration at the point of hitting a ball, is combined with this plantar foot force analysis method, new design development of golf shoes to increase comfort and ball flight distance will be available. 1. Address acting, forces concentrated in rare foot regions and lateral foot of right foot. Back swing top acting, relatively high force occurred in medial forefoot region of left foot and forefoot region of right foot. Impact acting, high force value observed in the lateral rarefoot region of left foot and medial forefoot region of right foot. Finish acting, force concentration observed on the lateral region and rarefoot region of left foot. 2. Forces were increased in address of right foot with clubs length increased. All clubs, back swing top acting, high force value observed in the lateral forefoot region of right foot. All clubs, in impact, high force value observed in the lateral rarefoot region of left foot and medial forefoot region of right foot. Finish acting, force concentration observed on the rarefoot region in driver and lateral foot region in iron on left foot. 3. Right foot forces distribution were increased in address, back swing top and left foot force distribution were increased in impact, finnish

Background: Frequency electrical stimulation is clinically being used in variable skin therapeutic conditions such as skin rejuvenation and hair disorder. There have been several clinical studies demonstrating the positive effect of electrical stimuli on hair regrowth. However, its exact mechanism is yet to be clarified. Objectives: The objective of this study is to investigate effects of different electrical parameter settings on hair growth by revealing the changes of dermal papilla cell in vitro and at microscopic level in animal tissue. Methods: Cultured dermal papilla cells (DPCs) and dorsal skin of rabbit were electrically stimulated with different parameter settings at alternating-current to find the optimal condition for hair growth. Cell viability and proliferation were measured by MTT. In addition, Ki67, proliferation marker, expression was measured by immunofluorescence. Hair growth-related gene expression in DPCs and the skin of rabbit were measured by RT-PCR. Results: At certain electrical settings, DPCs responded well and their proliferation was successfully induced. Wnt/β -catenin, Ki67, p-ERK and p-AKT expressions in DPCs increased at certain frequency settings. Dermal thickness and hair related genes (PDGF, VEGF, SOX9 and KGF) expressions in the skin of rabbit also significantly increased. Conclusion: These data suggest that electrical stimulations at certain electrical settings, may give more effective therapeutic outcomes for hair growth.

The inverted papilloma and squamous cell carcinoma are common neoplasia in the sinonasal cavity and nasopharynx, but the incidence of these tumors are very low and the study on the oncogenesis or biological activity of the tumor cells are not well known. This study was designed to evaluate the oncogenic roles of the p53 gene and the proliferative activity of the tumor cells in the inflammatory polyp, inverted papilloma and squamous cell carcinoma. The experiment was carried by the immunohistochemical stains about the p53 protein, PCNA and Ki-67, histochemical stain about the AgNORs. and flow cytometric analysis about the DNA ploidy using the formalin fixed paraffin embedded tissues. The frequency of the expression of p53 protein was 0%(0/16 cases) in the inflammatory polyps, 18.8% (3/16 cases) in the inverted papillomas, and 87.5%(14/16 cases) in the squamous cell carcinomas. The labelling index(%) of the PCNA and Ki-67 was 5.3% and 3.3% in the inflammatoy polyps, 29.6% and 25.2% in the inverted papillomas, and 51.9% and 36.8% in the squamous cell carcinoma. The expression of the PCNA and Ki-67 was distributed in the periphery of the tumor islands of the inverted papilloma and was distributed in the both of center and periphery of the tumor islands of the squamous cell carcinoma. The number of nuclear AgNORs was increased in the order of inflammatory polyps (0.96), inverted papillomas(1.34) and squamous cell carcinoma(2.09). The frequency of the DNA aneuploidy was 0%(0/16 cases) in the inflammatory polyps, 18.8%(3/16 cases) in the inverted papillomas. and 12.5%(2/16 cases) in the squamous cell carcinomas. Above results indicates that the changes of the p53 gene and proliferative activity of the tumor cells are involved on the oncogenesis and the biological activity of the inverted papilloma or squamous cell carcinoma in the nasopharynx and sinonasa cavity.

Heat stroke is a life-threatening illness characterized by an elevated core body temperature that rises above 40% and central nervous system dysfunctions that results in delirium, convulsions, or coma. Heat stroke is subdivided into two forms, classic and exertional. Since strenuous exercise is one of the major exacerbating and precipitating factors, the incidence of exertional heat stroke is high among young adult, especially military personnel undergoing military training. Exertional heat stroke commonly causes rhabdomyolysis, lactic acidosis, acute renal failure, shock and pulmonary edema. We report a case of heat stroke with rhabdomyolysis, acute renal failure, disseminated intravascular coagulopathy(DIC) after strenuous exercise. A 18 year old man was admitted to the hospital because of loss of consciousness. He was a wrestler and he had tried to lose 6kg in weight by jogging and strenuous exercise on that summer day with hot temperature. The development of this illness was favoured by much clothes inappropriate for that environmental condition with a purpose to enhance sweating, and by restricted intake of water and food. On admission, the blood pressure was 80/50mmHg, and body temperature was 39.4℃ with stuporous mentality. Laboratory finding were as follows : in complete blood cell count, hemoglobin was 16.7g/dL and platelet count was 158,000/ mm³. In blood chemistry, AST 1061U/L, ALT 201U/L, BUN 30mg/dL, Cr 2.2mg/dL, LDH 941IU/L, CK 696IU/L were resulted. In arterial blood gas analysis, pH 7.39, pCO₂ 30mmHg pO₂ 86mmHg, HCO₃ 18.4mEq/L, O₂ saturation 96.7% were resulted. In urinalysis, specific gravity 1.025, protein 3+, erythrocyte 2+ were resulted. In brain imaging study, brain CT finding was normal. After appropriate treatments with rapid cooling, hydration and supportive care, he improved with alert mental status. On 2nd hospital day, in laboratory result, thrombocytopenia and coagulopathy were appeared and renal insufficiency was aggravated. So he was treated with platelet concentrate and fresh frosen plasma for DIC, and enough hydration for appropriate urine volume preservation. After all, On 22nd hospital day, he fully recovered and discharged. Nowadays, with followed for some duration, he is wellbeing with no complications.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

이 연구는 1993년도에 우리나라의 연간 슬러지발생량이 약 3500만m³에 이르고 있으며, 이들 대부분이 매립되고 있다. 그러나 매립부지의 확보가 점점 어려워 지고 있으며 아울러 매립처분비용도 상승하고 있기 때문에 oil화, 퇴비화등으로 재자원화 하는 방법과 소각후의 소각회를 유효이용하는 방법 등이 연구 개발되고 실용화되고 있다. 슬러지의 oil화는 현재 연구단계에 있으나 앞으로 슬러지의 유효이용기술로서, 가장 좋은 방법이 되리라 기대되고 있다. 그러나 소각후의 소각회의 이용방법은 현재 일본등에서는 실용화 되어 건설자재 등으로 다양하게 이용하고 있다. 우리나라에서도 서울시 등을 비롯한 대도시에서는 하수처리장에서 발생하는 슬러지를 소각한 후에 소각회를 건설 자제용으로서 지자체의 공사에는 반드시 사용하도록 하는 제도를 만든다면 유효이용방법으로 충분한 타당성이 있을 것이다. 이때 소각방법으로는 용융소각방법이 보다 효과적일 것이다. With increasing sewage and wastewater sludge, it has become difficult to dispose the sludge by landfilling and ocean dumping. To solve this problem, efforts have been made to delelop sewage and wastewater sludge utilization technologies in many advanced countries. Some technologies have already been developed; conversion of sludge to compost and fuel, producing artificial light-weight aggregate from ashes. This paper describes the technical status of sludge utilization technologies.

이기호,김상만,이득주,최희정,한인권 대한비만학회 2003 The Korean journal of obesity Vol.12 No.3

연구배경: 폐경 전후에서의 체중 증가와 여성호르몬과의 연관성이 지속적으로 논의되어왔다 교감 신경계는 지방대사를 촉진하여 대사적 열생산을 증가시키는 작용을 가지고 있으므로 이와 관련하여 베타3아드레날린 수용체의 유전자형이 폐경여성에서 여성호르몬 대체요법 이후의 체중증가와 연관이 있는지를 밝히고자 본 연구를 시행하였다. 방법: 1995년부터 2002년 5월까지 삼성제일병윈 비만클리닉 및 갱년기 클리닉에 방문하여 여성 호르몬 대체요법을 시행 받았으며, 폐경에 관련한 과거력, 여성 호르몬 투여 전후의 체중, 체질량 지수에 대한 자료를 확보할 수 있곤, 베타3 아드레날린 수용체 유전자의 다형성을 분석한 92명을 최종 연구 대상자로 하였다. 결과: 베타3 아드레날린 수용체 유전자 다형성 분포는 Trp64Trp형 39.1%, Trp64Arg형 25.0%,Arg64Arg형 34.8%,로 나타났다 여성호르몬 투여 전 체중의 평균은 61.07±7.06이었으며, 여성 호르몬대체요법 후 체중 변화의 평균은 1.28±3.20 증가로 나타났으나, 통계적으로 유의하지 않았다 β3 아드레날린 수용체 유전자 아형에 따른 체중의 평균 변화는 Trp64Trp형에서 1.86±2.94 증가, Trp64Arg형 0.74±2.97 증가, Arg64Arg형 1,00±3.61 증가로 나타났으나 이들 모두 통계적 유의성은 없었으며, 세 아형간의 변화량도 유의하지 않았다. 결론: 폐경여성에서 여성호르몬 대체요법 후 체중이 증가하였으나 통계적으로 유의하지 않았으며, β3아드레날린 수용체 유전자 아형에 따른 차이를 관찰할 수 없었다. Background: The study results to determine the relationship between postmenopausal estrogen use and weight gain have not been consistent. Genetic studies have reported the association of BMI with the beta3-adrenergic receptor gene polymorhism. This study as designed to indentify association of beta3-adrenergic receptor gene polymorhism with weight gain related to HRT in postmenopausal women. Methods: 192 postmenopausal women at a general hospital, Bariatric and climacteric clinic have been collected. Subtypes of beta3 adrenergic receptors were measured and physical, anthropomeric data including body fat and BMI was obtained before and after HRT. Results: Arg/Arg group was 34.8%, Trp/Arg group was 25.0%, Trp/Trp group was 39.1%. Mean weight gain in 192 postmenopausal women was 1.28±3.20 kg and the percent changes in weight gain between initial and final point was 2.32±5.66% but these resulst had no statistical significance (p>0.05). Weight gain(%) were 2.24%(95% C.I 0.35~4.13) in Arg/Arg group, 1.08%(-1.17~3.29) in Trp/Arg group and 3.18%(1.49~4.92) in Trp/Trp, but these results did not show statistical significance(F=1.13, p=0.03). Conclusion: Polymorphism of beta3 adrenergic receptor gene was not associated with weight gain after HRT in postmenopausal women. From these results, we may conclude that polymorhism of beta3 adrenergic receptor may not be the predicting factor to understand the weight gain after HRT in postmenopausal women.
