This study was carried out to evaluate the aberrant expression of ?? protein using immunohistochemical method in 10 malignant melanoma and 10 melanocytic nevi. Eight out of 10(80%) and two out of 10(20%) showed positive reaction in the nucleus of malignant melanoma and benign melanocytic nevi, respectively. In conclusion, the demonstration of ?? protein in benign melanocytic nevi greatly hinders the possibility of a diagnostic use of ?? immunostaining in differentiating malignant melanoma from benign melanocytic nevi.

Regardless of the health care reform in Korea, the nations health status did not substantially improve. Taking into account, the government considers Lifetime Health Monitoring System to improve the nations health status. The purpose of this study is to set policy guidelines for construction of Lifetime Health Monitoring System in Korea. It is suggested that Lifetime Health Monitoring System should be directed towards; reform of health examination, construction of health information system, activation of health life-style, and activation of primary care. It is needed that a working relationship with hospitals, public service agencies and other providers of health care to provide health care services according to lifetime. Especially health center has important role in Lifetime National Health Monitoring System. It is clear that when there is cooperation of public and private health sector and dynamic leadership and support, national health status can be substantially improved. The purpose of Lifetime Health Monitoring System is to enable people to gain greater control over the determents of their own health by lifetime periodic health care services.

This study was conducted to investigate the effect of exercise program of public health center for health promotion. The participated subjects was consisted of 12 middle-aged female classes and 18 elderly classes. Before the exercise program started, we examined health history questionnaire and physical activity questionnaire. The exercise was consisted of stretching, folk dance. The obtained results were as follows: In the elderly class, the circumstance of waist. hip and W/H was significantly decreased compared to before the exercise started(p<.05). In addition, the systolic blood pressure of elderly class was significantly decreased compared to before the exercise started(p<.05). In middle-aged female class, there was similar trends to elderly class in spite of no significant difference. From these results. it was suggested that exercise program of public health center for health promotion was contribute to health promotion and quality of life.
IDI형 정적연소기에서의 연락공각도가 연소특성, 및 열유속에 미치는 영향

We use the IDI type constant volume which is applied Indirect Injection strafied charge method to solve the problems of lean-burn such as misfire and cycle-variation. There are many factors to effect on the combustion charateristics in indirect injection strafied engine. The passagehole angle is the most important factor in that determine the direction of inflowed fuel and flame to the main chamber. In this study, we measured combustion pressure and wall temperature to examine the combustion characteristics and heat flux with the passagehole angle in the main chamber.

This study was conducted to investigate the effect of exercise program of public health center on diabetes and hypertension patients. The participated subjects was 11 diabetes patients and 12 hypertension patients, respectively. The exercise was consisted of 10 min. of stretching and 20 min. of aerobic exercise and 20 min. of exercise for muscle strength for 3 months. The obtained results were as follows: The total cholesterol concentration, post prandial glucose level and systolic blood pressure of total subjects was significantly decreased compared to before the exercise started(p<.05). In diabetes patients. post prandial glucose level was significantly decreased compared to before the exercise started(p<.05). In hypertension patients. the value of systolic blood pressure after exercise was significantly decreased compared to before the exercise started(p<.05). From these results, it was suggested that exercise program of public health center improved the condition of diabetes and hypertension.

The skin lesions of herpes zoster are classically limited to a single dermatome and most cases of multidermatomal herpes zoster have contiguous skin lesions. Simultaneous involvement of two noncontiguous dermatomes is very rare and it has been referred to as zoster duplex unilateralis or bilateralis, depending whether one or both halves of the body are involved. A 67-year-old woman presented with a group of painful vesicles on the right buttock and thigh, and left anterior chest and back. The Tzanck smear and skin biopsy were consistent with a herpetic infection. We report a rare case of zoster duplex bilateralis. (Ann Dermatol 21(4) 423~425, 2009)

We investigated a total of 335 samples of Korean native mushroom extracts as part of our lipoxygenase (LOX) inhibitor screening program. Among the mushroom-methanolic extracts we investigated, 35 exhibited an inhibitory activity greater than 30% against LOX at a concentration of 100 ${\mu}g/mL$. Especially, Collybia maculata, Tylopilus neofelleus, Strobilomyces confusus, Phellinus gilvus, P. linteus, P. baumii, and Inonotus mikadoi exhibited relatively potent LOX inhibitory activities of 73.3%, 51.6%, 52.4%, 66.7%, 59.5%, 100.0%, and 85.2%, respectively. Bioassay-guided fractionation led to the isolation of inoscavin A from the methanolic extract of P. baumii, which showed the most potent activity and was identified by spectroscopic methods. Specifically, inoscavin A exhibited potent LOX inhibitory activity with an $IC_{50}$ value of $6.8{\mu}M$.

Measurements of local heat transfer coefficients in the cooling flow passage of the ventilated disc brake are made. Flat surfaces in the flow passage have been modified to helically fluted surfaces to better dissipate heat caused by the friction between the disc and the pad in braking. Thermochromic liquid crystals and shroud-transient technique were used to accurately measure local heat transfer coefficients. The Reynolds numbers tested are 30,000, 50,000 and 70,000, the helix angle is fixed at 60?°, and the diameter of tube is 7㎝. The results show that the local heat transfer coefficients with helically fluted surfaces are maximum 89.3% to 179% higher than values measured on the flat surface.
