Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

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.

1980년대 말과 1990년대를 거치면서 동북아지역환경협력은 UN 산하 환경관련기구들을 중심으로 진행되어 왔다. 그러나 리더십이 UN을 벗어나 일본과 같은 나라로 넘어가도 여전히 문제는 남는다. 동북아국가들 사이에는 오랜 역사를 통하여 적대감이 존재하여 왔다. 현재 추진중인 지역환경레짐은 이러한 측면에서 매우 고적인 현상임에는 틀림없으나 일본은 동북아환경문제에 있어서 나름대로의 이니셔티브를 장악할 가능성이 있다. 본 논문은 동북아지역에 형성된 다자간 환경협력이나 양자간 환경협력의 실례를 살펴보면서 동북아 환경문제에 대한 협력 가능성의 한계를 부각시켜 본다.

This study was carried out to determine the effects of different storage conditions on bacterial quality of raw milk. During the summer, the ratio of samples which showed total bacterial count below 4.0 x 10 exp(6)/ml were 51.5% in bulk cooled milk and 17.4% in, water cooled milk. The bacterial count of raw milk stored below 5℃ at farms was investigated according to different milk collecting method. 1. The ratio of samples that had total bacterial counts less than 4.0 × 10 exp(6)/ml, as the legal limit was 78.5% in tanklorry, and 43.6%, in ordinary truck transportation system. 2. The ratio of samples that had coliform bacteria below the number of 1.0 x 10 exp(5)/ml was 84.2% in tanklorry, and 58.3% in ordinary truck transportation system. 3. The ratio of samples that had thermoduric bacteria below the number of 1.0 × 10 exp(6)/ml was 80% in tanklorry, and 46.7% in ordinary truck transportation system, 31.1% of latter samples was above 1.0 × 10 exp(5)/ml. 4. The ratio of samples that had psychrotrophic bacteria above the number of 1.0 × 10 exp(6)/ml was 1.5% in case of tanklorry, and 38.3% in ordinary truck transportation system.

1. PKC activator인 PMA는 일차배양 HTSE세포로부터의 뮤신분비를 0.1μM 농도에서 30%, 1μM 농도에서 80% 가량 증가시켰다. 2. 식물 유래 성분으로, flavonoid의 일종인 TFR은 일치배양 HTSE 세포로부터의 뮤신분비를 10μM 농도에서 50%, 100μM 농도에서 80% 가량 증가시켰다. 3. 양이온성 폴리펩티드인 PLL 및 PLA는 일차 배양 HTSE 세포로부터의 뮤신분비를 0.01 - 10μM 농도에서 용량의존적으로 감소시켰다. 4. 결론적으로, 본 연구에서 얻어진 결과들은 새로운 거담제 및 점액용해제나 단백분해 효소제가 아닌 호흡기 류신의 생성/분비를 조절해 줄 수 있는 신개념의 약물을 개발함에 있어 극히 일부분이나마 단서를 제공하고 있다고 하루 수 있을 것이다. In the present study, we tried to investigate whether phorbol myristate acetate(PMA), trihydroxymethoxy-flavanone rutinoside(TFR) and cationic polypeptides significantly affect mucin release(secretion) from cultured hamster tracheal surface epithelial cells. Confluent primary hamster tracheal surface epithelial (HTSE) cells were metabolically radiolabeled with 3H-glucosamine for 24 hr and chased for 30 min in the presence of each agent to assess the effect on 3H-mucin release. The results were as follows : (1) Both PMA and TFR significantly increased mucin release from cultured HTSE cells ; (2) Cationic polypeptides including po1y-L-lysine(PLL, mw 7,500) and poly-L-arginine(PLA, mw 10,800) significantly inhibited mucin release from cultured HTSE cells, in a dose-dependent manner. This finding suggests us that PMA and TFR be further studied for the possible use as mild expectorants and cationic polypeptides might function as a regulator for hyper-secretion of mucus, both by direct acting on airway mucin-secreting cells, during the treatment of chronic airway diseases.

Internet telephony provides voice communication services with added flexibility for multimedia extension at a lower cost compared to traditional telephone systems. We implemented an internet telephony system as an overlay network without a centralized server, using a distributed hash table (DHT). Compared to the current server-based internet telephony system, our system is fault-tolerant, scalable, and can be flexible extended to various services and advanced to integrated service. To demonstrate the high flexibility of our DHT-based internet telephony system, we made our system cooperate with web servers. Web users can check up others online states and establish voice communication sessions to online users at a mouse click. This technology can be tipplied to more complex services such as multimedia messaging or video conference service.

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.

Cleidocranial dysplasia is a rare and autosomal dominent disorder characterized by aplasia or hypoplasia of the clavicles, an open fontanelle, dental abnormalities, and short stature. A 17-year-old female who presented with short stature and subsequent delay in eruption of permanent teeth is described. she showed the abnormal hypermobility of the shoulder, ocular hypertelorism and concave nasal bridge. Radiographs revealed the underdeveloped maxilla, defect of the cranium in the fontanelle region, and aplasia of the clavicles. Characteristically, panoramic view revealed near parallel-sided borders of the ascending ramus and downward curvature of the zygomatic arch with hypoplasia. The prolonged retention of deciduous teeth with delayed eruption of permanent teeth and multiple embedded supernumerary teeth were striking. Radiographic and clinical investigations revealed Cleidocranial dysplasia.
