N/A Objective: Middle-aged and geriatric diseases are becoming prevalent in developing countries and some industrialized nations. The present study was undertaken to determine the prevalence of middle-aged and geriatric diseases in Hwasun County, a rural area of Korea, and to examine the correlation between them and various clinical parameters. Methods: Population-based cross-sectional study by random cluster sampling of registered residents over 39years of age was performed. Out of the 3,138 subjects scheduled for the survey, 2,021 residents (male 812, female 1,209) underwent the actual examinations(response rate:64.4%). We examined their weight, height, blood pressure, diet pattern, past and family history, alcohol-drinking and smoking history, and various laboratory parameters. Result: The mean body mass index (BMD was 22.8 ±3.8. In BMI criteria, the crude prevalence of obesity was found to be 24.6% (grade I obesity' 22.9%, grade II obesity; 1.7%). We found the increasing hypertension, diabetes mellitus, hypercholesterolemia as BNI increased. Overall crude prevalence was 21.4% for hypertension defined as BP (blood pressure) ≥140/90mmHg or subject on medication, and 16.1% for BP ≥160/100mmHg or subject on medication. The crude prevalence of diabetes mellitus, hypercholesterolemia, alcoholic liver disease, ischemic heart disease diagnosed by electrocardiography were 6.2%, 6.0%, 4.4%, and 2.3%, respectively. These prevalence were found to be relatively lower than those of reported elsewhere in the world. Conclusion ' These data indicate that middle-aged and geriatric diseases in the rural area of korea are becoming prevalent, although they are less prevalent than in the urban area or advanced countries. We hope that the present study contributes to understand the prevalence of middle-aged and geriatric diseases in the rural area of K and to prevent and control them adequately.

Blepharospasm and apraxia of lid opening(ALO) are non-paralytic causes of involuntary eyelid closure. Clinically it is difficult to differentiate blepharospasm and ALO, and these two conditions are sometimes associated. We report a case of pretarsal blepharospasm presenting as apraxia of lid opening. 55-year-old woman was noted to have voluntary eye opening difficulty. We synchronously record the electromyographic(EMG) from the levator palpebrae superioris and the orbicularis oculi muscles in this patient. This results suggested that she has a variant of blepharospasm due to abnormal contraction in the pretarsal orbicularis oculi.

N/A Objective: The positive rates of hepatitis B virus (HBV) markers differ according to age, sex, race, locality, sexual behavior, socioeconomic conditions, immunologic and genetic factors. It is a well-known fact that Korea is one of the endemic areas of HBV infection in the world. Past many reports have presented that the gositive rates of HBsAg and anti-HBs in Korea were about 6~14Yo and 30-62%, respectively. However there were a few epidemiological surveys of rural communities on the positive rates of HBV markers. The present study undertook to determine the positive rates of HBsAg and anti-HBs in Hwasun county, a rural area of Korea. Methods We performed Population-based crosssectional study by random cluster sampling of registered residents in Hwasun county. Out of the 2,920 subjects (4.1%) scheduled for the survey, 1,913 residents under- went the actual examination. We tested EG3sAg and anti- HBs by reversed passive hemagglutination (HPHA) and passive hemagglutination (PHA), respectively. Results: The positive rates of HBsAg and anti-HBs in all subjects were 5.6% and 20.8%, respectively, and those were 5.4% and 20.4% in 168 pregnant women, respectively. The positive rate of HRsAg was significantly higher in male (8.2%) than in female (4.0%) (p< 0.01). The positive rate of anti-HBs was 21.4Yo in female, but it was not significanly higher than in male (19.6%). There were no significant differences according to age groups in the positive rates of HBsAg and anti-HRs. Conclusion There are no significant changes in the positive rates of HBsAg and anti-FB3s between the present study for Hwasun county and past many reports in Korea. Although the rate of hepatitis B vaccination increased significantly, it was not effective because that the vaccinated total numbers in the rural area of Korea were probably small. So it is very important to undertake a nationwide program of hepatitis E3 immunization and to educate the residents in rural areas of Korea.

Naphthalene sublimation technique is used to investing the average and local heat transfer from the circular rod, and to determine the average and local heat transfer from the circular rod with and without squarc wing type mixing vane in axial flow. The experiments are performed for a circular rod and flat plate with and without mixing vane in wind tunnel. In comparison with flat plate and circular rod in axial flow, averaged Nusselts namber is increased 2 times as the increase of Reynolds namber with mixing vane. Longitudinal vortex induced by square wing type has the stronger vortex strength. so square wing type vortex generator shows an effect in downstream.

Fouling is very serious problem in heat exchanger because it rapidly deteriorates the performance of<br/> heat exchanger. Cross-flow heat exchanger with vortex generators is developed, which enhance heat<br/> transfer and reduce fouling. In the present heat exchanger, shell and baffle are removed from the<br/> conventional shell-and-tube heat exchanger. The naphthalene sublimation technique is employed to<br/> measure the local heat transfer coefficients. The experiments are performed for single circular tube,<br/> staggered array tube bank and in-line array tube bank with and without vortex generators. Local and<br/> average Nusselt numbers of single tube and tube bank with vortex generator are investigated and<br/> compared to those of without vortex generator.
