Korean hemorrhagic fever is a disease that most patients recover without sequelae after clinical course of febrile, hypotensive, oliguric, diuretic and convalescent phases. In the autopsy findings of Korean hemorrhagic fever patients, coagulation necrosis of anterior pituitary gland is known as one of the most characteristic macroscopic findings, but there has been rare reports of panhypopituitarism in patients with Korean hemorrhagic fever. Recently we have experienced panhypopituitarism in two patients who had past history of Korean hemorrhagic fever. First patient, who had Korean hemorrhagic fever 2 and half years ago was presented with chief complaint of sexual dysfunction, Second patient, who had Korean hemorrhagic fever 12 years ago was presented with Addison crisis-like manifestations. Both patients were confirmed as panhypopituitarism by combined anterior pituitary function test. There was no evidence of hypothalamic or pituitary diseases by history and several tests including brain CT scan. Past history of Korean hemorrhagic fever was confirmed by the high titers of antibody against Hantaan virus in patients serum. Our experience shows that Korean hemorrhagic fever can be a cause of panhypopituitarism and high index of suspicion should be maintained to detect hypopituitarism in patients with past history of Korean hemorrhagic fever when appropriate symptoms and signs are present.

A numerical investigation on head losses and flow qualities for a large cavitation tunnel without impeller

최정규,김형태,이창섭,이승재 대한조선학회 2022 International Journal of Naval Architecture and Oc Vol.14 No.1

In this study, a numerical investigation of the flow quality and total head loss of a large cavitation tunnel is conducted. Excluding the impeller, the entire tunnel is modeled, and calculations are conducted for the test section's maximum speed of 15 m/s. The numerical study showed that an edge chamfer eliminates the pressure drop in the test section, resulting in a constant cavitation number downstream, and that a diverging top diffuser, as opposed to a flat top, induces upward flow at the exit of the test section. Also, the effectiveness of the flow straightener and honeycomb in reducing turbulence has been validated. In the test section, the turbulence intensity is 0.10% and the uniformity is 0.20%. The 2nd corner has the highest head loss due to the shaft. Due to the relatively high speed, significant head losses are observed in the test section, diffuser, and first corner.

Background: Korea set up a new diagnosis-related group as a demonstration project in 2009. The new diagnosis-related group was reformed in 2016. The main purpose of the study is to identify the effect of reform on coverage of national health insurance. Methods: This study collected inpatient data from a hospital that contains medical information and cost from 2015 July to 2016 June. The dependent variable was the coverage of national health insurance. The dependent variable was divided by total, internal medicine partition, surgical partition, and psychiatric partition. To analyze the effect of the reform, this study conducted an interrupted time series analysis. The final sample included 23,695. Results: The health insurance coverage of internal medicine has the highest, followed by surgery and psychiatry. The health insurance coverage of bundle payment is higher than that of unbundled payment. The proportion of bundled payment and non-benefit decreased and the proportion of unbundled payment increased. The coverage of national health insurance significantly increased after policy reform in internal medicine partition (p-value=0.0356). Conclusion: The results of the study imply that policy reform enhanced the coverage of national health insurance in internal medicine. The government needs to monitor side effects such as an increase of unbundled payment.

Background: Korea set up new diagnosis related group (DRG) as demonstration project in 2009. The new DRG was reformed in 2016. The main purpose of study is to identify the effect of reform on accuracy of payment. Methods: This study collected inpatient data from a hospital which contains medical information and cost from 2015 to 2016. The dependent variables were accuracy of total, bundled, unbundled payment, and payment for procedures. To analyze the effect of reform, this study conducted a multi-variate regression analysis adjusting for confounding variables. Results: The accuracy of payment increased after policy reform. The accuracy of total, bundled, unbundled payment, and payment for procedures significantly increased 3.90%, 2.92%, 9.03%, and 14.57% after policy reform, respectively. The accuracy of unbundled payment showed the largest increase among dependent variables. Conclusion: The results of study imply that policy reform enhanced the accuracy of payment. The government needs to monitor side effects such as increase of non-covered services. Also, leads to a considerable improvement in the value of cost unit accounting as a strategic play a role in development of DRG.

경제학에서 생물학을 받아들일 수 있는가?

최정규 대동철학회 2012 大同哲學 Vol.59 No.-

이 글은 경제학과 생물학의 교류 속에서 경제학이 어떤 식으로 진화 생물학에서의 발견을 수용해왔는지를 되돌아보는 목적으로 씌어졌다. 경제학에서의 진화 패러다임의 수용의 역사는 길지만 각 시기마다 경제학에서 진화 패러다임을 이용함으로써 ‘무엇을’ 밝히고자 했는가는 다르다. 어떤 시기에는 경제주체들의 합리성을 전제하지 않더라도 합리적 의사결정 모형이 도출해낸 결론과 동일한 균형에 도달할 수 있음을 보이는 데 진화 패러다임이 이용되기도 했고, 또 어떤 시기에는 특정 환경하에서는 최적화보다 모방이 더 효과적이을 보이는데 진화 패러다임이 이용되곤 했다. 최근 들어서면서 경제주체의 사회적 선호 혹은 도덕적 감정 등이 확인되고, 또 이렇나 감정이 경제적 성과에 크게 영향을 준다는 것이 확인되면서 그것의 기원 및 유래를 밝히는 데 진화 패러다임이 매우 중요하게 다루어지기 시작했다. 이러한 과정은 한편으로는 진화 패러다임을 통해 규명하고자 하는 것이 변화하는 과정이기도 했고, 다른 한편으로 경제이론의 발전과 함께 시장, 경쟁 그리고 경제주체들을 기존과 다른 방식으로 이해하기 시작하는 과정이기도 했다. This Thesis reviews the academic interaction between economics and biology and the way that economics has incorporated the theoretical development in biology. In the long history of the interaction between two disciplines, it differs that 'what' economics would focus on by using the biological analogy in each stage. In earlier stage, evolutionary approach were widely used for proving that market process reaches the same efficient equilibrium without assuming the rationality of economic agents and in the later stage for proving that imitation could be more effective than optimization under certain condition. Recently in economics as social preferences and moral sentiments have been recognized as an important issue, the biological approach received attention by economists because it could shed lights on the origin of social preferences and moral sentiments. The academic interactions between two disciplines have been changing as what economists would show with the biological analogy changes. At the same time biology helps economists understand the market, competition and economic agents from the different view points.

Objectives The aim of this study was to investigate the correlated factors that may influence the length of stay in mental health related facilities. Methods We chose 2253 patients with mental illness using a stratified multi-stage cluster sampling from 48 psychiatric hospitals, twelve psychiatric clinics, five psychiatric welfare facilities, and five mental rehabilitation facilities. The investigation involved psychiatrists, psychology practitioners, and social workers, and lasted from August 1, 2008 to November 15, 2008. Assessment and investigation of diverse factors was performed using one-way analysis of variance in order to examine their influence on length of stay. Results Factors showing significant correlation with length of stay included the types of mental health related facilities, age, marital status, socioeconomic status, type of medical security, familial support, type of admission, diagnosis, age of onset of the illness, number of admissions, severity of psychiatric symptoms, daily living and social function, GAF score, prominent thought/perception disability, memory/orientation disturbance, odd behavior/prominent regression, personal hygiene, communication/personal relationship, management of money, and public transportation/facility utilization. Conclusion Findings of this study suggest that the type of mental health related facilities and the type of medical security are the most significant factors showing correlation with length of stay.
