Background: Surgical correction needs to be considered when diaphragm eventration leads to impaired ventilation and respiratory muscle fatigue. Plication to sufficiently tense the diaphragm by VATS is not as easy to achieve as plication by open surgery. We used pneumatic compression with carbon dioxide ($CO_2$) gas in thoracoscopic diaphragmatic plication and evaluated feasibility and efficacy. Methods: Eleven patients underwent thoracoscopic diaphragmatic plication between January 2008 and December 2013 in Pusan National University Hospital. Medical records were retrospectively reviewed, and compared between the group using $CO_2$ gas and group without using $CO_2$ gas, for operative time, plication technique, duration of hospital stay, postoperative chest tube drainage, pulmonary spirometry, dyspnea score pre- and postoperation, and postoperative recurrence. Results: The improvement of forced expiratory volume at 1 second in the group using $CO_2$ gas and the group not using $CO_2$ gas was $22.46{\pm}11.27$ and $21.08{\pm}5.39$ (p=0.84). The improvement of forced vital capacity 3 months after surgery was $16.74{\pm}10.18$ (with $CO_2$) and $15.6{\pm}0.89$ (without $CO_2$) (p=0.03). During follow-up ($17{\pm}17$ months), there was no dehiscence in plication site and relapse. No complications or hospital mortalities occurred. Conclusion: Thoracoscopic plication under single lung ventilation using $CO_2$ insufflation could be an effective, safe option to flatten the diaphragm.

The purpose of this study was to evaluate the information searching behavior of consumer by type of medical institution. A questionnaire survey was conducted of 1,507 persons who were selected through a multi-stage stratified area cluster sampling in nationwide level, excluding Jeju-Do. Personal survey was conducted through door-to door survey from 27 July to 10 August 1999. The main results of this research was as following; 1. The proportion of information searching of respondents ranged from 91.5-95.2%. Even though the proportion of user in university hospital was slightly high, there was not significant statistically by type of medical institution. In terms of information source, personal informer was most common information source in all type of medical institution. Public informers were more frequently used in university hospital visitors and professional informer in general and university hospital visitors. 2. Comparing to searching intensity, user informer and professional informer's influences were more powerful, but not statistically significant. In analysis of unit influence for information source, written informer or public informer was more powerful in clinic visitor, professional informer and written informer in university hospital visitor. 3. Information which consumer want to know mostly were about on special potential and career of physician. The clinic visitor wanted to know about institutional location and kindness of medical personnel. The university hospital visitor also wanted to know about facilities and convenience of process. Comparing to institution selection criteria of consumers at 1991, quality related criteria were recognized more importantly in outpatient and dental services. But in case of inpatient services, convenience factor was recognized more importantly. In conclusion, the effort for specific marketing plan by type of medical institution should be needed. And more concern on information searching behavior of consumer will be needed.

Statins are competitive inhibitors of hydroxy-3-methyl glutaryl coenzyme A (HMG-CoA) reductase and used most frequently to reduce plasma cholesterol levels and to decrease cardiovascular events. However, statins also have been reported to have undesirable side effects such as myotoxicity and hepatotoxicity associated with their intrinsic efficacy mechanisms. Clinical studies recurrently reported that statin therapy elevated the level of liver enzymes such as ALT and AST in patients suggesting possible liver toxicity due to statins. This observation has been drawn great attention since statins are the most prescribed drugs and statin-therapy was extended to a larger number of high-risk patients. Here we employed rat primary hepatocytes and microarray technique to understand underlying mechanism responsible for statin-induced liver toxicity on cell level. We isolated genes whose expressions were commonly modulated by statin treatments and examined their biological functions. It is of interest that those genes have function related to response to stress in particular immunity and defense in cells. Our study provided the basic information on cellular mechanism of statin-induced cytotoxicity and may serve for finding indicator genes of statin -induced toxicity in rat primary hepatocytes.

본 논문은 FDI를 종속변수가 아닌 설명변수로 삼아 FDI가 제도에 미치는 영향에 초점을 맞춘다. 제도를 Rodrik의 분류방법에 따라 시장조성제도, 시장규제제도, 시장안정화제도 및 시장복지제도 등 4종류로 분류하여 FDI가 제도에 어떠한 영향을 미치는지 분석한다. 1985~2009년 기간 동안 186개국가의 패널자료를 이용하여 후진국과 선진국으로 구분하여 제도결정방정식을 추정한다. 고정모형과 FDI의 내생성을 고려한 system GMM을 이용해서 FDI, FDI와 민주주의의 상호관계항이 4종류의 제도에 미치는 영향에 초점을 맞춘다. 추정결과는 다음과 같다. 첫째, 대부분의 추정결과 FDI는 4종류의 제도에 유의한 양의 영향을 미치지 못하고 있다. 둘째, FDI와 민주주의의 상호관계항은 시장규제제도를 제외한 나머지 3개 종류의 제도에 유의한 양의 영향을 미치고 있다. 즉, FDI는 직접적으로 제도에 영향을 미치지 못하지만, 민주주의가 발달한 경우에 간접적으로 시장조성제도, 안정화제도와 시장복지제도에 영향을 미친다. FDI가 유치국의 제도에 직접적으로 영향을 미치지는 못하지만, 긍정적 영향을 미치기 위해서는 유치국가의 민주주의발달이 필요하다는 점을 알 수 있다.
