The present study examined the structure and patterns of ethnic identity in a sample of Korean-Chinese parents and their adolescents residing in the Jilin Province in China. The ethnic identity of these participants(total :148 parents:100 adolesents:48) includes two major components : Korean identity and Chinese identity. Each of these components was measured in three different modalities : behavioral, affective and cognitive. The results are summarized as follow ; 1) Generational comparisons between Korean identity scores of parents and adolescents indicated similarities in the modalities of cognitive and behavioral identities. Both groups shared a Korean orientation manifested in their high level of Korean behavior and cognition. However, both groups also shared a relatively high level of Chinese identity. In summary, dual identity appeared to be preserved over time. The parents scored higher than the adolescents in their affective modality of Korean identity. Chinese identity was scored higher in the adolescents than korean identity in their affective modality. The generational comparisons indicated that the adolescents were acculturated in their affect than their parents. 2) Comparison of men and women in the strength of identity' component showed higher cognitive scores among the men. in Korean identity, compared with Chinese identity. Men were more identified with "Chinese" and "Korean" in the affective component of their identity.

연구배경: 그레이브스병의 치료에는 항갑상선제, 수술 및 방사성 요오드법이 선택되어 사용되고 있다. 이중 항갑상선제는 가장 많이 선호되고 있으나 낮은 관해율과 높은 재발율로 장기간 치료기간이 요구된다. 저자들은 그레이브스병 환자에게서, 선택되는 치료법의 선호도와 각 치료법의 관해율을 조사하고자 본 연구를 시행하였다. 또한 본 연구에서는 항갑선제 치료의 적정기간을 평가하고자 하였다. 방법: 아주대학교병원에 내원한 환자 중 1년 이상 추적관찰이 가능한 205명의 그레이브스병 환자를 대상으로 조사하였다. 항갑상제군, 수술군 및 방사성 요오드군은 각각 170명, 29명 그리고 6명이었다. ROC curve를 이용하여 약물치료의 예후예측인자를 분석하였다. 결과: 1) 그레이브스병 환자의 치료 방법의 선택은 항갑상선제군, 수술군 및 방사성 요오드군 각각 170명(83.0%), 29명(14.1%) 그리고 6명(2.9%)으로 항갑상선제 치료가 가장 선호되었다. 2) 그레이브스병의 관해율은 항갑상선제군, 수술군 및 방사성 요오드군에서 각각 60.0%(102/170명), 96.5%(28/29명) 그리고 83.0%(5/6명)으로 수술군이 가장 높았다. 3) ROC curve의 AUC는 치료기간과 진단시 TBII가 각각 0.709 및 0.648이었고 적절한 약물투여 추적 관찰기간은 26개월이었다. 결론: 그레이브스병의 일차 치료법으로는 항갑상선제가 선호되고 있으나 수술 및 방사성 요오드 치료군에 비해 상대적으로 낮은 관해율을 보였다. 따라서 항갑상선제 치료로 26개월 이상 관해가 되지 않을 경우에는 치료 방법의 변경을 고려하는 것이 관해율을 높이는데 도움이 될 것으로 생각된다. Background: Graves' disease in an organ specific autoimmune disease. Three kinds of therapeutic modalities (antithyroid drugs, ablation with radioactive iodine and subtotal thyroidectomy) are frequently performed for the management of this disease. The most popular therapeutic policy for the disease in Korea is antithyroid treatment. We analysed and compared the remission rates of all three modalities for Graves' disease, and evaluated the antithyroid modality to determine the correct duration of treatment. Subjects & Methods : The medical records of 205 patients with Graves' disease were reviewed. For the evaluation of the antithyroid modality medical treatment, antithyroid drugs were administered for more than 1 year. The prognostic factors associated with remission were analysed by means of an ROC curve. Results: 1) Of the 205 patients, proportions that received medical therapy, subtotal thyroidectomy and radioiodine therapy were 83.0, 14.1 and 2.9%, respectively. 2) The remission rates of the medical therapy, surgery and radioiodine therapy were 60.0, 96.5 and 83.0%, respectively. 3) The remission rate of the medical therapy was associated with the duration of medication and TBII activity. The determined proper duration for the antithyroid treatment was 26 months from the ROC curve analysis. Conclusion: The above results suggest that the proper duration of antithyroid treatment for Graves' disease is 26 months, after which time the subtotal thyroidectomy or radioiodine therapy should be considered if the disease has not remitted (J Kor Soc Endocrinol 18:24∼31, 2003).

The aim of this study was to investigate the effects of a 2-week ingestion of grape seed extract(300 mg/day) on cardiovascular response and vascular endothelial cell function at rest and during handgrip exercise in prehypertensive individuals. Nine prehypertensive men, aged 24.6±3.1 yrs, repeatedly participated in both grape seed extract trial and placebo trial in a randomized, double-blind, crossover manner. While the subjects ingested grape seed extract or placebo in a 2-week trial, their cardiovascular response, blood vessel diameter, blood flow volume, and vascular endothelial cell function at rest and during handgrip exercise were measured. Each variable was compared between two trials as well as between two tests simultaneously using a repeated two-way ANOVA. Main result of the present study were as follows: 1) Systolic blood pressure decreased significantly at rest after the 2-week ingestion of grape seed extract. 2) Systolic blood pressure and mean blood pressure decreased significantly during handgrip exercise after the 2-week ingestion of grape seed extract. 3) Flow-mediated dilation volume and % flow-mediated dilation increased significantly after the 2-week ingestion of grape seed extract. It was concluded that 2 weeks of ingestion of grape seed extract would have an positive effect on cardiovascular response and vascular endothelial cell function at rest and during handgrip exercise in prehypertensive men. Future research investigating the effects of various period and amount of ingestion of grape seed extract during aerobic exercise including large muscle group would be warranted.

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

Objectives The aims of this study are to estimate the prevalence of the DSM-IV psychiatric disorders in the Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI), and to compare those with previous studies. Methods The Korean Epidemiologic Catchment Area study Replication (KECA-R) was Conducted between August 2006 and April 2007. The sampling of the subjects was carried out across 12 catchment areas. A multistage, cluster sampling design was adopted. The target Population included all eligible residents aged 181o 64 years. Face-to-face interviews were conducted with the Korean version of Composite International Diagnostic Interview (K-CIDI) based on the DSM-IV (N=6,510, response rate=81.7%). Results A total of 6,510 participants completed the interview. The lifetime and 12-month prevalence rates for all types of DSM-IV disorders were 30.0% and 17.3%, respectively. Those of Specific disorders were as follows : 1) alcohol use disorder, 16.2% and 5.6% ; 2) nicotine use disorder, 9.0% and 6.0% ; 3) specific phobia, 3.8% and 3.4% ; 4) major depressive disorder, 5.6% and 2.5% ; and 5) generalized anxiety disorder, 1.6% and 0.8%. Data relating to nicotine and alcohol use disorder revealed a very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among females than males. Conclusion The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in the distribution of psychiatric disorders across the country and times were observed.

이만승,이광섭,이진영,김성돈,김준수 대한금속재료학회 2004 대한금속·재료학회지 Vol.42 No.10

Solvent extraction experiments of Sm were performed from chloride solution with PC88A and saponified PC88A. Solvent extraction reaction of Sm with PC88A and the corresponding equilibrium constant were evaluated from the experimental and ionic equilibria data as follows Sm^(3+)_(aq)+ 1.5H₂A_(2,org)= SmA_(3,org)+ 3H^(+)_(aq) , K = 0.33. The predicted distribution coefficients of Sm agreed well with the experimental results. The distribution coefficients of Sm with saponified PC88A and the values of equilibrium pH depended on the initial extraction conditions. When the concentration of PC88A was in excess of that of Sm, saponification of PC88A greatly enhanced the extraction of Sm. (Received June 21, 2004)

비누화 PC88A에 의한 NdCl₃와 SmCl₃용매추출의 화학모델

이만승,이광섭,이진영,김성돈,김준수 대한금속재료학회 2004 대한금속·재료학회지 Vol.42 No.10

A chemical model was developed to estimate equilibrium constant for the solvent extraction of Nd and Sm from chloride solution with saponified PC88A. The model could be employed to predict the distribution coefficient of metal from the initial extraction conditions. The model consisted of chemical equilibria, mass balance, charge balance and solvent extraction reaction. By applying the model to the experimental conditions and data, equilibrium constants for the solvent extraction of Nd and Sm were obtained. The effect of the saponification of PC88A on the extraction of Nd was explained in terms of the equilibrium constant obtained in this study and the change of equilibrium pH. The predicted distribution coefficients of Nd and Sm agreed well with those measured. (Received July 14, 2004)
