The purpose of this study was to analyze the effect of long-term care utilization on health care utilization of the elderly. The sample in this study includes 23,269 people older than 65 who are extracted from 2009-2010 long-term care insurance and health insurance claim data. The study group was divided into two groups, namely acute care hospitals and long-term care hospitals. Two part model were used for statistical analysis and instrumental variables analysis were used for controlling endogeneity in the group of long-term care hospitals. This study evaluated the impact of long-term care costs on the probability of health care utilization experience and costs of health care utilization. The results showed that an increase in long-term care costs was associated with an increase in utilization of acute care hospitals, but it was associated with a decrease in utilization of long-term care hospitals. When 1% increase in long-term care costs was associated with 0.5% decrease in costs of long-term care hospitals. On the basis of results, this study concludes that long-term care utilization and utilization of long-term care hospitals for older people are substitutes.

최근 IT 분야의 가장 큰 화두인 유비쿼터스 혁명을 주도하고 있는 네트워킹 기술은 급격한 기술 변화로 다른 분야에 많은 영향을 끼치고 있다. 이러한 네트워킹 기술의 발달은 더 이상 정적인 네트워크가 아닌 움직이는 네트워크 즉, 네트워크 이동성 (network mobility) 개념을 등장시켰다. 조직 혹은 기업에서는 작업 프로세스의 향상뿐만 아니라 제품 생산 능력 향상의 기회를 제공해 줄 수 있는 워크플로우 시스템은 아직 모바일 네트워크간의 동적인 환경에서 사용상의 제약이 있다. 따라서 본 연구에서는 모바일 네트워크의 이동성을 고려하여 워크플로우를 지원하는 방법을 모색하고자 한다.

Acantholytic acanthoma is a benign tumor of epidermal keratinocytes. It presents as a solitary asymptomatic papule in which acantholysis is a histologic hallmark. Its histologic finding is so much similar to those of other acantholytic dermatoses such as Hailey-Hailey disease and pemphigus vulgaris. But the clinical features including the solitarity and asymptomaticity do not fit into any specific acantholytic dermatoses. We describe a 49-year-old female patient with this peculiar benign tumor on her calf.

나환자의 피부병변에서 inducible Nitric Oxide Synthase 와 Cyclooxygenase - 2 의 발현
김명화(Myung Hwa Kim),최유원(Yoo Won Choi),최혜영(Hae Young Choi),명기범(Ki Bum Myung) 대한피부과학회 2001 대한피부과학회지 Vol.39 No.2
Background: Nitric oxide (NO) produced by activated macrophages through the action of iNOS is the key molecule in the killing mycobacterium. Prostaglandins produced by the action of COX-2, also, are the important mediators of inflammation and other pathophysiologic process. A complex relationship is emerging with regard to cross-talk between the NO and COX-2 pathways. Objective: The purposes of this study were to investigate the expression of iNOS and COX-2 across the spectrum of leprosy in the paraffin-embedded skin lesions, to demonstrate the interaction between iNOS and COX-2 expression, and to demonstrate the differences in the cell types expressing the iNOS or COX-2. Method: In the paraffin-embedded skin lesions of 30 new cases of leprosy(TT, n=4; BT, n=4; BL, n=7; LL, n=l5), iNOS and COX-2 expression were detected by using immunohistochemical staining. Results: iNOS expression was 2.0-55.8%(mean 15.9%) and the level of expression of iNOS in TT(31.2%) and BT(32.6%) lesions was significantly higher than that of BL(11.1%) and LL(8.6%) lesions(p<0.05). COX-2 expression was 3.6-74.5%(mean 27.1%) and the level of expression of COX-2 in TT(59.2%) lesions was significantly higher than that of BT, BL and LL lesions(p<0.05). There was positive correlation between iNOS and COX-2 expression, that is, the lesions which expressed high level of iNOS also expressed COX-2 highly. The correlation was statistically significant(r=0.535, p<0.05). The overall level of COX-2 expression (27.1%) was higher than that of iNOS expression (15.9%), and when compared the expression of them across the spectrum of leprosy, COX-2 expressed higher than iNOS in TT and LL lesions.Conclusion: Both iNOS and COX-2 were expressed in all types of leprosy skin lesions and the level of iNOS expression in TT and BT lesions was significantly higher than that of BL and LL lesions. The level of expression of COX-2 in TT lesions was significantly higher than that of BT, BL and LL lesions. These results suggest that iNOS and COX-2 have important roles in anti-mycobacterial activities in leprosy lesions. The positive correlation between iNOS and COX-2 expression suggests that NO and COX-2 might interact synergistically or additively rather than suppress each other.

친일희곡의 극작술 연구―연극경연대회 작품상 수상작을 중심으로
김명화 ( Kim Myung-hwa ) 국제어문학회 2004 국제어문 Vol.32 No.-
This paper examines the dramaturgy of the dramas written in the period of Japanese colonial power on the Korean peninsula, and which followed and propagandized the Japanese system. Such disposition is considered `pro-Japanese` in Korea. Pro-Japanese dramas appeared when Japan`s imperial desire got into its stride since the late 1930s, especially during the early 1940s when the `Theatre Contest` took place three times in a row. This paper has studied the dramaturgy of the three dramas that were rewarded for the excellence in that Contest, “The Chinese Date Tree” by Ryu Chi-Jin, “History” by Song Young and “San-Ha-Yoo-Jung” by Kim Sung-Gu. Their works have particular significance not only because they disseminated Japan`s political ideology of the time, but also because they inherited them to an artistic level. Moreover, these dramatists participated actively in the Korean theatre and therefore it is assumed that their dramaturgies have greatly affected the thenceforth theater world of Korea. “The Chinese Date Tree”, the first won production of the theatre Contest, compares the small land of Korea and the wide land of Manchuria. It rationalizes the Japanese colonial system then and prevails upon the fact that Japan`s desire of imperialism would avail itself. The second won piece, “History”, grapples with the conflict and compromises between Korea`s tradition and Japan`s newly established policies. “San-Ha-Yoo-Jung”, the third rewarded piece of the Theatre Contest, lyrically presents the desirable figures of the public during wartime by showing cooperation among the people. Consolidating the characteristics of the three dramas while researching their dramaturgies, first, they appeal to the emotions of their familial organization. Second, the basic conflict of their work are the opposing opinions of the new and the old, in other words, the Korean tradition and the newly established Japanese structure are handled by different generations. Third, which includes the first and the second attributes, points out that the new system and the ideas ultimately win and are consumed in terms of familial emotions. However, individualism and liberalism, which were the characteristics of the modern western world, were rejected. Last, the modern qualities compared to the modern times of the West which rest upon individualism has very much of totalitarianism. Looking at these characteristics, they are closely related to the fact that Korea`s modern qualities could not help being distorted. This is because satire or the tragic nationalism that developed during the 1920s and the 1930s, which through the period refracted to become an enlightening totalitarianism, family-centrism, corresponds with the locus of the modern history of Korea.

Background: The purpose of this study was to propose a method for developing a measure of hospital-wide all-cause risk-standardized readmissions using administrative claims data in Korea and to discuss further considerations in the refinement and implementation of the readmission measure. Methods: By adapting the methodology of the United States Center for Medicare & Medicaid Services for creating a 30-day readmission measure, we developed a 6-step approach for generating a comparable measure using Korean datasets. Using the 2010 Korean National Health Insurance (NHI) claims data as the development dataset, hierarchical regression models were fitted to calculate a hospital-wide all-cause risk-standardized readmission measure. Six regression models were fitted to calculate the readmission rates of six clinical condition groups, respectively and a single, weighted, overall readmission rate was calculated from the readmission rates of these subgroups. Lastly, the case mix differences among hospitals were risk-adjusted using patient-level comorbidity variables. The model was validated using the 2009 NHI claims data as the validation dataset. Results: The unadjusted, hospital-wide all-cause readmission rate was 13.37%, and the adjusted risk-standardized rate was 10.90%, varying by hospital type. The highest risk-standardized readmission rate was in hospitals (11.43%), followed by general hospitals (9.40%) and tertiary hospitals (7.04%). Conclusion: The newly developed, hospital-wide all-cause readmission measure can be used in quality and performance evaluations of hospitals in Korea. Needed are further methodological refinements of the readmission measures and also strategies to implement the measure as a hospital performance indicator.

Trichorrhexis nodosa is the most common hair shaft anomaly in which there is a distinctive response to injury. The hair is fragile and on examination pale `node-like' swelling may be observed. It may affect normal hair following excessive or repeated trauma, or may occur after minimal trauma if there is an inherent defect in keratin synthesis causing abnormally brittle hair. We report a case of localized trichorrhexis nodosa in a 42-year-old male who had scratched frequently for the relief of the pruritus in the parietal area. Scanning electron microscopy revealed longitudinal fissures and fracture in the cortex. A paint brush effect was noted at the site of fracture. (Korean J Dermatol 2000;38(3):387~390)
