1991년3월부터 8월사이에 대구시에 소재한 1개의 대학병원의 종합검진센타에 내원해서 종합검진을 받은 남자 422명(69.9%)과 여자 182명(30.1%)을 대상으로 하여 심헐관계질환의 위험요인들의 전체적인 분포를 보았다. 평균 연령은 남자가 43.3(표준편차, 10.3), 여자가 44.4(표준편차, 10.8)였다. 남자에서 연령에 따라 0.05 수준에서 통계적인 유의성을 보인 위험인자는 혈청 총콜레스테롤(TC). 트리글리세라이드(TC), 고밀도 지단백콜레스테롤(HDL), 저밀도 지단백콜레스테롤(LDL), 수축기혈압, 비체중, A형행동양상이었으며 생활습관으로서는 음주, 흡연, 규칙적인 운동, 우유와 커피섭취, 수면 등이었다. 여자에서는 TC, TG, LDL, 수축기와 확장기혈압, 비체중 그리고 커피섭취와 수면 등이었다. 남자에서 총콜레스테롤의 평균은 181.7mg/dl(표준편차, 32.2), 여자는 182.5mg/이(표준편차, 42.2)였다. 대부분의 위험인자들은 구미의 수준에 미치지 못했으나 남자에서 흡연율이 전체적으로 61.8%로 높으 수준이었으며 특히, 20~29세가 72.9%, 30~39세가 75.2%로서 다른 연령군에 비해 상대적으로 높았다. 여자에서는 전체적으로 6.0%에 지나지 않았다. 확장기혈압 90mmHg 이상을 고혈압자로 정의했을 때의 유병률이 여자 전체대상자에서 24.7%로 높았으며 50-59세는 표본수가 적어서 문제가 되었으나 53.1%였다. 어떤 인구집단내에서 총콜레스테롤의 평균이 200mg/dl 미만이면 고혈압과 흡연의 인구집단의 수준에 관계없이 관상동맥질환(coronary heart disease)의 발생은 드문 것으로 보고가 되고 있으므로 당분간 관상동맥질환 발생률의 급속한 절대적인 증가는 힘드리라 사료된다. 그러나 이러한 결과는 본 연구의 대상자들이 대표성을 지니지 못하며 건강검진센터에 자발적으로 내원한 사람들이므로 해석에 주의를 요한다. Authors examined the distributions of the risk factors for the coronary heart disease in the 422 male (69.9%) and 182 female (30.1%) visitors to the health examination center of a university hospital located in Taegu March to August 1991. Mean age of males was 43.3(standard deviation, SD 10.3) and that of females was 44.4(SD 10.8). Total cholesterol(TC), triglyceride (TG), high-density lipoprotein and low-density lipoprotein cholesterol(LDL), systolic blood pressure, Quetelet index, and Type A Behavior Pattern, and some of life habit variables(alcohol intake, smoking, regular exercise, milk and coffee intake and sleeping) were statistically significant in age groups of the males(P<0.05). In the females, TC, TG and LDL, systolic and diastolic pressure, Quetelet index, coffee intake and sleeping were statistically significant in age groups (P<0.05). Mean of total cholesterol was 181.7㎎/dl(SD,32.2) in males and that of females was 182.5㎎/dl(SD,42.2). Most of the risk factors levels were lower than the Euro-Americans', while smokers were high with 61.8%, especially 72.9% in 20-29 age group and 75.2% in 30-39 age group in males. In females, smokers were just 6.0%. Hypertensives defined by more than 90mmHg diastolic pressure were 24.7% in females, particularly 53.1% in 50-59 age group, but size of the strata was rather small(N=49). In the light of the report that coronary heart disease is uncommon irrespective of population levels of smoking and hypertension, where average total blood cholesterol level in a population is low(<200mg/dl), it is not likely that the absolute increase of the number of the coronary heart disease will increase markedly in the near future. But cautions should be exercised in interpreting the results of this study due to the lack of representativeness and volunteerism. .

We consider a consumer self-selection model in which a regulated firm faces two market segmants wig differing valuation of quality of telecommunication services and examine some economic implications from the behaviors of the firm. In the context of a regulated monopolist, even though the results depend on the degree of privatization, the firm could lower the quality of the low-end model and reduce the price of the high-end in order to alleviate cannibalization. This justifies the provision of universal service policy in the telecommunications market. Based on this self-selection model, we also analyze an extended model of product introduction and show that the monopolist will introduce new product with the same introduction time of social planner. However, when we consider competition among firms, the market equilibrium may not guarantee the efficient time of product introduction.

Generalizes edema and hypoalbuminemia are relatively common presenting manifestations in many clinical situations. The differential diagnosis of hypoalbuminemia include; Kwashiorkor, synthetic dysfunction of the liver, and excessive protein loss as in nephrotic syndrome. In systemic lupus erythematosus (SLE), hypoalbuminemia and generalized edema are most commonly due to protein loss associated with lupus nephritis; gastrointestinal involvement is uncommon, and therefore protein loss through the gastrointestinal tract is quite rare. We report a case of a protein losing enteropathy (PLE) associated with SLE. The patient was referred to out hospital for generalized edema, arthralgia and facial rash. After clinical evaluation, the patient met the criteria for the SLE diagnosis; hypoalbuminemia with general edema was consistent with a protein losing enteropathy. After two weeks of therapy with parenteral high dose glucocorticoid, the patients was improved in laboratory findings as well as clinical symptoms.

The purpose of this study is to investigate ⑴ the role of the Christianity in Korean women's education, ⑵ the evaluation of Korea women's education based on Christianity, ⑶ the tasks that Christianity must perform for the future Korean women's education. The result of this study as follows: First, the role of Christianity is developmental process of Korea women's education has been differently performed in times. Specifically, the role of Christianity in enlightenment period was release from traditional customs, the role of Christianity in Japanese Imperialism period was enlargemant of patriotism and independent consciousness, the role of Christianity in after 8·15 liberation was establishment of democratic consciousness. Second, the evaluation of Christianity for Korean women's education suggested to positive and negative role. Finally, the most important tasks for future women's education would have new understanidng on the mission of Christianity and recognition of the historical and social need.

Optimum conditions of PCR amplification for gibberellin-related genes such as GOX2 and GAI were determined by altering annealing temperature and primer concentration in order to minimize mispriming PCR products. Selective amplifications of GOX2 and GAI genes were performed with 40 ng template DNA, 0.5 μM M13 forward/reverse primer and annealing temperature of 62 ℃. 30 cycles of PCR reaction profiles were denaturation for 60 sec at 94 ℃, annealing of primers for 60 sec at 62 ℃, extension of primers for 60 sec for 72 ℃, final extension for 5 min at 72 ℃ and cooling at 4 ℃.

Dentigerous cyst originates from the crown of the tooth has been completely formed by accumulation of fluid between the reduced enamel epithelium and the tooth crown. In the incidence age, dentigerous cyst occur with a more even distribution among the age groups but there is noticeable drop in the patients younger than ten. There is greater incidence of cysts in the maxilla than in the mandible, but dentigerous cysts differ in the respect ; there are found more often in the lower jaw. We experienced 4 cases of dentigerous cysts which is rare in first decade and acquired satisfying result by surgical excision.

Clinicopathologic analysis of ameloblastoma in 24 cases and their ultrastructural and immunohistochemical studies, especially to cytokeratin expressions according to morphologic classification were performed to clarify the tumor cell differentiation and origin. Reaction with broad spectrum and high molecular weight cytokeratin were generally positive in the stellate cell of the follicular and acanthomatous ameloblastoma, suggesting more squamous differentiation than peripheral basal cell type. Although ultrastructually common origin from oral epithelium was evidenced by presence of tonofilaments and desmosome, variations were prominent among the different histopathologic types of tumor. In granular cell ameloblastoma there were pleomorphic osmiophilic lysosome-like granules.
