Cerebral venous sinus thrombosis is an uncommon condition with dramatic clinical presentation of progressive headache, papilledema, seizures, focal neurological deficits and coma. It has many etiologies including infections, hypercoagulability, inflammatory disorders, head trauma and cancer. Although it is relatively uncommon, vascular complications are well documented extra-intestinal manifestations of inflammatory bowel disease. Among them, Crohn disease is an extremely rare cause of cerebral vascular disease. We present a case of cerebral venous sinus thrombosis in Crohn disease successfully treated by high dose steroid therapy.

The present study aims to develop of evaluation method for college education. This study consiste of two parts: to identify the corelation between the freshmen's scores of pre-test for entrance examination and their scores of freshmen's year, and to make suggestions for the improvement of evaluation method in college on the basis of the former study results. Seen from the above mentioned aspects of this study, this study has meanings in its seek for a rational curriculum improvement and in its research of the pilot curriculum which presupposes the alleged system of limited graduation quota. This research which is conducted by above mentioned purpose andmeanings can be summerized as follows; 1) The freshmen's mean score of the-pre-test of college entrance examination is 192. 38. Among the departments of natural scienc attained the most higher score(204.22). and department of arts and gymnastics 162. 02 which is below average score. 2) In the achivements of the freshmn'e year the departments of natural sciences obtained the best results, followed by the departments of arts and gymnastics, education, and cultural aciences in oder. 3) There is no corelation between the pre-test scores of college entrance examination and the college achivement results. 4) The mean scores of the major and teaching subjects geneally increas as they go up into the advanced school years. 5) Each department has their own method of evaluation. 6) Teaching syllabus is asked to be presented whit the direction of clas, contents, purpose, and specific items of evaluation. 7) Achivements of college work must be evaluated by the normal distribution curve with the facts about specific factors of the study and students group taken into consideration.

28세 남자가 내시경적 점막절제술을 통해 저등급 위MALT 림프종으로 진단되었다. 병기설정을 위해 18F-FDG PET 검사를 시행하였고 우측 쇄골상부, 우측상/하부 기관주위, AP window 부위에 강한 섭취가 관찰되어 전이성 림프절로 판단하였다. 그러나, 우측 쇄골상부 림프절에서 시행한 절제생검에서 만성육아종성염증소견이 관찰되었고 조직의 결핵 중합효소연쇄반응에서도 양성 반응을 보였다. 2개월간 항결핵제의 사용 후 시행한 추적 컴퓨터단층촬영 검사에서 림프절 크기의 감소를 보여 최종적으로 위 MALT 림프종에서 광범위 림프절 전이로 오인된 동시성 림프절 결핵으로 진단되었다. A 28-year-old man was diagnosed as gastric MALT lymphoma in diagnostic EMR (endoscopic mucosal resection). He subsequently underwent an 18F-FDG PET. 18F-FDG PET showed intense multifocal uptake in right supraclavicular, right upper and lower paratracheal, and AP window areas that was considered radiologically to represent widespread metastatic lymphadenopathy. Excisional biopsy of a supraclavicular lymph node, however, revealed chronic granulomatous lymphadenitis with a positive reaction of Tb-nested PCR. After antituberculosis treatment for 2 months, a follow-up CT scan showed complete resolution of the lesions. Intense 18F-FDG uptake could be due to an infectious process such as synchronous tuberculous lymphadenitis. Therefore, this could mimic a malignant condition such as lymphoma with extensive lymph node metastasis due to a false-positive finding, which may lead to a misdiagnosis.

Association between International Diversification Strategy and Future Stock Price Crash Risk

( Seun Young Park ) 한국회계학회 2020 회계학연구 Vol.45 No.2

This paper tests whether the corporate global diversification lessens the information asymmetry between the firm and the investors and thus associated with a negative future stock price crash risk in Korean stock market. As the increased integration of global economies, an increasing number of firms have pursued global diversification over time. However, less attention has been given to the economic consequences or benefits in equity market from global diversification. Using a large sample of firms listed in KOSPI over 2000-2017, this paper finds that the degree of corporate globalization is less likely to experience firm-specific future stock price crashes. The results are consistently robust across alternative measures of globalization and crash risk. Moreover, the additional finding shows that the negative association between globalization and future crashes is pronounced when the firms are not followed by analysts. And discounts for global firms significantly decrease in economic downturns, suggesting an incremental hedging benefit of diversification. These findings are robust when the estimates account for the endogeneity of globalization. Overall, the empirical findings suggest that corporate diversification may create an business and information environment that partly mitigates the managerial opportunistic motives to withhold bad news, supporting positive effect of global diversification.

A Study on the Future Accounting Quality of First Time IFRS Adopters Choosing Deemed-cost Option

( Seun-young Park ),( Sung Whan Park ) 한국회계학회 2019 회계학연구 Vol.44 No.6

This paper tests whether the firm’s application of deemed-cost for their fixed assets on the date of transition to IFRS are associated with their future firm accounting quality, as measured by ex-post comparability (De Franco et al. 2011) and earnings quality. In this study, we posit that management discretion on the deemed-cost option allowed at the time of IFRS adoption can affect the relationship between firm’s deemed-cost adoption and their future accounting comparability and earnings quality. For empirical analysis, we use firms listed in KOSPI between 2011 and 2015, and provide the transitional financial statements in 2010. Our empirical results are as follows: first, the comparability and the earnings quality of the deemed-cost adopters are higher than non-adopters. Second, regarding the impact of the different types of deemed-cost on accounting quality, those firms which adopt the fair value amounts on the transition date to IFRS show higher comparability and earnings quality than those of the firms apply past revaluation amounts. Last, the positive association between firm’s deemed-cost adoption and accounting quality is more pronounced when firms change the depreciation methods and the useful life of their fixed assets. Overall, the results imply that firm managers’ voluntary adoption of deemed-costs during the introduction of IFRS may be more meant to provide the market with transparent and relevant information related to firm’s fair value.

Family Control, Product Market Competition and Firm Performance

Seun-Young Park,Hyun-Han Shin 서울대학교 경제연구소 2016 Seoul journal of economics Vol.29 No.3

In this paper, we try to determine the effect of the presence of family shareholders on company performance in the absence of external corporate governance. Our empirical results using Anderson et al. (2009, 2012)’s family firm data suggests that family firms exhibit superior firm performance relative to nonfamily firms when the level of product market competition is weak, suggesting that the family control is an effective internal corporate governance mechanism that can compensate for weak external corporate governance. Furthermore, a family firm’s performance results in being superior to nonfamily firms’ performance in weak competitive markets, regardless of whether the CEO of a family firm is a founder, heir or professional manager. These findings suggest that the family control is an effective organizational structure in mitigating agency problems and enhancing firm performance when external corporate governance is weak.

Diverticular disease of the colon is quite common in developed countries, and its prevalence increases with age. The large majority of patients will remain entirely asymptomatic. Nonetheless, an estimated 20% of those affected may manifest clinical illness, mainly diverticulitis, with its potential complications of abscesses, fistulas, and obstruction as well as lower intestinal hemorrhage. A case was experienced involving of diverticulitis operated due to recurrent left lower abdominal pain in 51-year-old female. We present this case with brief review of the related literature.
