Glomus tumor is a tumor arising from glomus body, a nodular form of arteriolovenular anastomosis that functions to regulate blood flow according to temperature. Gastrointestinal glomus tumors are rare and most frequently occur in the stomach as a subepithelial tumor. A 46-year-old woman presented with an incidental finding of a subepithelial tumor in the stomach. Endoscopic ultrasonography (EUS) showed a 1.4×1 cm sized well circumscribed heterogeneous hypoechoic tumor with a few tubular structures in the fourth sonographic layer of the gastric wall. Characteristically, more hypoechoic halo equal to the echogenecity of proper muscle layer enclosed the tumor. Contrast enhanced abdominal computerized tomography (CT) revealed high enhancement of tumor up to the same level of portal vein in arterial phase and this enhancement persisted to portal phase. For histolgogic confirmation and treatment, endoscopic enucleation was attempted but failed due to fibrotic adhesion with the surrounding tissue. Histologic findings of biopsy specimen were compatible with glomus tumor. Although it is difficult to diagnose glomus tumor preoperatively, these characteristic findings in EUS and CT seem to be useful in distinguishing glomus tumor from other tumors arising from the fourth sonographic layer of gastric wall.

박종필(Jong-Pil Park),천영우(Young-Woo Chon),이익모(Ik-Mo Lee),김홍관(Hong-Kwan Kim),황용우(Yong-Woo Hwang) 한국위험물학회 2021 한국위험물학회지 Vol.9 No.2

This study performed HAZOP, which is a qualitative risk assessment for the API(Active Pharmaceutical Ingredient) process, and aimed to check the solvent change, the root cause, to reduce the derived risk, select accident scenarios and high-risk solvent materials, and identify the substitution of low-risk solvent substances. This study conducted the Consequence Analysis(CA), which is a quantitative risk assessment, to determine the extent of damage in the event of a chemical accident caused by solvents. In addition, the ALOHA of the US Environmental Protection Agency was utilized, and the estimated impact scope was quantified as the cost of disaster loss, in addition to performing a cost-benefit analysis that considers safety and economic feasibility. The difference in the impact scope in the toxic exposure was relatively larger than the difference in the impact in the impact scope in the liquid fire of methanol and ethanol. Due to the characteristics of the pharmaceutical industry, it can be fatal to the human body if methanol remains in pharmaceuticals. Accordingly, it is recommended to use ethanol instead of methanol. This study examined solvent change and suggested a cost-benefit analysis that considers safety and economic feasibility. As a study on the intrinsic safety that replaces high-risk solvents with low-risk solvents, it is expected to contribute to the prevention of serious industrial accident caused by chemicals.

연구배경: 심방세동은 심방의 확장과 심실 기능이 저하된 경우에 자주 동반되는 비교적 흔한 부정맥이다. 하지만 심방세동의 병인에 대해서는 아직 명확하지 않다. 본 연구는 발작성 심방세동을 갖는 환자에서 도 플러 심근능력 지표 (Tei index)을 이용하여 심실 기능을 평가하고자 하였다. 방법: 발작성 심방세동을 갖는 환자 25명(남 14, 여 11, 61±3세)과 대조군 25명 (남 11, 여 14, 58±10세)을 대상으로 하였으며, 75세 이상의 고령 환자, 고혈압, 당뇨, 관상 동맥질환, 판막질환을 갖는 환자는 제외하였다. Tei index는 isovolumetric contraction time (ICT)과 isovolumetric relaxation time (IRT)를 ejection time (ET) 으로 나눈값으로 정의하였다. 결과: 양 군 간에 임상적인 양상은 큰 차이가 없었고. 심 초음파상 심실 중격 두께(8.9±1.8 vs 11.6±3.2 mm, p<0.05), 좌심실 질량지수 (85.6±45 vs 107±33 g/m2, p<0.05), 는 발작성 심방 세동군에서 의의 있게 높았다. 좌심실의 확장기말 길이 (49±4 vs 51±4 mm), 수축가말 길이 (29.7±3 vs 33.1±5 mm), 좌심실 구혈률(69±6 vs 65±8%)은 유의한 차이가 없었다. 좌심방의 전후 길이 (32.8±4.3 vs 39.5±8.2 mm, p<0.05),은 발작성 심방세동 군에서 의의 있게 높았으며 좌심방면적 분획변화율(fractional area change)은 (39.5±8.2 vs 32.8±4.3%, p<0.05),은 의의 있게 낮았다. 발작성 심방세동 군에서 IRT (59±23 vs 76.5±21 msec, p<0.05),는 길었으며, ET (332.9±23 vs 303±27 msec, p<0.05),는 짧았다. ICT (43±21 vs 53±17 msec)는 통계학적으로 차이가 없었다. Tei index (0.33±0.01 vs 0.4±0.12, p<0.05)는 발작성 심방세동 군에서 의의 있게 높았다. 결론: 본 연구에서 발작성 심방세동의 병인에 있어서 좌심방의 기능 저하뿐만 아니라, 좌심실의 이완기 장애 도한 중요한 역할을 하고 있음을 알 수 있었다. Background and Objective : Atrial fibrillation is comparative common arrhythmia, when left atrium is enlarged and the ventricular function of the heart is fallen. However, cause of a Atrial fibrillation is not confirmed. This research wished to evaluate the function of the ventricle using Doppler myocardial performance index (Tei index) in patient who have paroxysmal atrial fibrillation. Subjective and Method : This study was done with 25 people (man 14, woman 11, age: 61 ±8 yr) who had paroxysmal atrial fibrillation and 25 people (man 11, woman 14, age: 58 ±10) who had no abnormality(control group). Among the researched patient, who have advanced age more than 75 years old, high blood pressure, diabetes, coronary arteries disease, valvular heart disease were excluded. Myocardial performance index(Tei index) defined by value that divide isovolumetric contraction time(ICT) and isovolumetric relaxation time(IRT) by ejection time (ET). Results : In aspect about clinical characteristics, the LV septal wall thickness(8.9 ±1.8vs 11.6 ±3.2 mm, p<0.05) and LV mass index (86±45 vs 107±33 g/m2, <0.05) were significantly higher in paroxysmal atrial fibrillation group than control group. The differences in LV end diastolic diameter (49±4 vs 51±4 mm), end-systolic diameter (29±7 vs 33±1 mm), left ventricle ejection (69±4 vs 65±5 %) between two groups were not statistically different. In paroxysmal atrial fibrillation group, LAAP diameter (33.1±4 vs 39.6±8.2 mm, p<0.05) was significantly long, left atrial fractional shortening (41±6 vs 36±6 %, p<0.05) was significantly low. In paroxysmal atrial fibrillation group, the isovolumetric relaxation time(IRT) was significantly long (59±22 vs 76±21 msec, p<0.05) and ejection time(ET) was significantly short (333±23 vs 303±28 msec, p<0.05). Isovolumetric contraction time(ICT) was not statistically different (43±21 vs 53±17 msec). Doppler Myocardial performance index(Tei index) was significantly high in paroxysmal atrial fibrillation group(0.30±0.1 vs 0.42±0.12, p<0.05). Conclusion : As result of this research, we can know that there is diastolic dysfunction of left ventricle as well as depression of left atrial function at paroxysmal atrial fibrillation and diastolic dysfunction of left ventricle can be a cause of paroxysmal atrial fibrillation.

박종필(Jong-Phill Park),김유성(Yoo-Sung Kim) 한국정보과학회 1999 한국정보과학회 학술발표논문집 Vol.26 No.2Ⅰ

고장 감내형 CORBA(Fault Tolerant Common Object Request Broker Architecture)는 분산객체 시스템 통합기술의 표준인 CORBA에 고장에 대한 회복수단을 제공하기 위해 제안되었다. CORBA에 고장 감내성을 추가하기 위해서는 객체단위의 중복그룹의 관리, 호출 구조 및 이에 따른 고장인지 및 회복기법이 필요하다. 기존에 제안된 분산시스템 환경에서의 고장인지 및 회복기법들은 프로세스 단위의 동작, 실행시간에 생성된 객체의 동적 환경구성 기능의 부재 등의 문제로 고장 감내형 CORBA에 적용시키기에는 많은 문제점을 가지고 있다. 따라서, 본 논문에서는 사용자에게 고장투명성과 연속적인 서비스 제공을 보장하는 고장 감내형 CORBA에 필요한 핵심기술인 객체 그룹간 고장인지 방법 및 고장으로 부터의 회복 메커니즘을 제안한다.

박종필 ( Jong Pil Park ),김형욱 ( Hyung Wook Kim ),이영관 ( Yung Kwan Lee ) 한국품질경영학회 2014 품질경영학회지 Vol.42 No.3

Purpose: The purpose of this study is to show whether there is a relationship between companies that promote CSR and hire indirectly as opposed to companies that only hire directly. Research results show that it is actually beneficial for the economy when companies implement the CSR, especially during times of economic recession. Methods: We have used data by collecting from the top 100 companies in Korea, which are the number of permanent employees, stock market registrations, companies that implemented the CSR, hiring directly and indirectly, etc., and analyzed them to carry out the regression analysis. Results: Research has shown that when companies implement the CSR and has many permanent employees, they also tend to hire employees indirectly. Conclusion: In the views of the whole economy, utilizing indirect hiring of employees can be a useful alternative, which can be accomplished by implementing CSR, and it must be recognized as the reason for producing more job opportunities within economies.

여교사의 행정직 진출 확대를 위한 연구

박종필(Park Jong Pil) 한국교육행정학회 2006 敎育行政學硏究 Vol.24 No.2

본 연구의 목적은 여교사의 행정직 진출에 부정적인 영향을 주고 있는 불평등적 요인 및 현상을 밝히고, 이러한 결과를 토대로 하여 양성 평등 차원에서 여교사의 행정직 진출을 확대 및 현 상황을 개선할 수 있는 방안을 모색하는 것이다. 이러한 연구 목적을 달성하기 위해 각종 통계 연보를 통해 여교사의 행정직 진출 상에 불평등 현상이 존재함을 밝히고, 전·현직 교장들을 대상으로 한 면접을 통해 여성의 행정직 진출을 저해하는 원인을 고찰하였다. 본 연구에서는 그 원인을 성역할 사회화, 가정과 직장, 사회적 통념 및 유대 관계 형성 등 4가지로 제시하였으며(물론 이들은 서로 관련되어 있다), 이러한 문제를 해결하고 여교사의 행정직 진출 확대를 위해 육아 문제 해결을 위한 사회적 및 국가적 차원의 노력, 승진 관련 제도의 보완, 여교사의 의식 변화를 위한 프로그램, 및 전체적인 인식 변화가 필요함을 제시하고 있다. The purpose of the study is to examine the inequal factors which have negative influence on female teachers' promotion to building administrators, and to suggest ways to expand and improve female teachers' opportunity of promotion based on the examination on the inequal factors. For the purpose of the study, the researcher selected five female ex- and incumbent principals using intensity sampling. Also, the researcher conducted informal conversational interviews to understand particular problems and unique situation in great depth. Based on the interview data, the researcher grouped inequal factors into four categories; sex-role socialization, the burden of child-caring and domestic duties, commonly accepted ideas on gender, and the androcentric perspective in korean society. To solve these problems and to expand the promotion opportunities of female teachers, the researcher suggests that our society and government should try to solve problems on the child-caring and provide and expand child-caring services for female workers. Also, the regulation on the advancement to administrative position should be changed to consider the female teachers' conditions, and the government and district office should provide programs on reforming of consciousness for female teachers and sex-role equality for school administrators.

해외직접투자기업의 후속투자 결정요인에 관한 연구: 한국 진출 다국적기업을 중심으로

박종필 ( Jongpil Park ),윤우진 ( Woojin Yoon ) 한국국제경영학회 2017 國際經營硏究 Vol.28 No.3

본 연구는 한국 진출 다국적기업의 후속투자 의사결정이 자회사 수준에서 어떠한 요인에 의해 결정되는가를 밝혀 보고자 하는데 그 목적이 있다. 보다 구체적으로 자회사의 입지 특성, 자회사의 현지화 수준 특성, 자회사의 지배구조적 특성이 후속투자 의사결정의 기제로 작용할 가능성이 있을 것이라는 관점 하에서 연구가설을 도출하고 이를 실증하였다. 실증분석을 위해서는 산업통상자원부에 외국인직접투자로 등록된 기업 중 2008년부터 2011년까지 투자가 이루어진 468개 제조업체를 대상으로 2006년부터 2015년까지 총 10년간 기업 연도별 불균형 패널 데이터, 4,114개 관측치를 구축하여 활용하였다. Hausman-Taylor 도구변수 방법론(HT-IV 추정)을 사용하여 분석한 결과, 첫째, 다국적기업의 현지 자회사가 클러스터에 입지할 경우 후속투자에 긍정적인 영향을 미치는 것으로 밝혀졌으며, 둘째, 다국적기업 현지 자회사의 연령이 낮을수록 후속투자 가능성이 높은 것으로 확인되었다. 셋째, 다국적기업 현지 자회사의 CI가 투자대상국을 연상하게 될수록 후속투자 가능성이 높아지며, 넷째, 다국적기업 현지 자회사의 관계사간 거래가 적을수록 후속투자 가능성이 높은 것으로 나타났다. 마지막으로, 다국적기업 자회사의 최대주주가 자연인이 아닌 법인격 실체를 가질수록 후속투자에 적극적인 것으로 분석되었다. The main goal of this paper is to investigate the determinants of sequential foreign direct investment (FDI) of multinational corporations (MNCs) in Korea. We hypothesized that the characteristics of subsidiaries` location, localization level and their governance structure are likely to act as the factors in deciding sequential FDI. In our empirical investigation, unbalanced panel data (2006~2015) which contains 4,114 observations was used for the analysis targeting 468 manufactures among foreign-invested companies registered in the Ministry of Trade, Industry and Energy (MOTIE)in Korea. Logit analysis based on Hausman - Taylor instrumental variable estimation (HT-IV) generally support our hypotheses. First, industry cluster location leads to positive effects on sequential investment. Second, local subsidiaries of NMCs in Korea with shorter history would have higher possibilities of sequential investment. Third, the stronger associations between host country and subsidiaries` corporate identities (CI) have higher possibilities of sequential investment. Forth, local subsidiaries tend to make sequential investment decisions when they have less relationship or cooperation with their other affiliates. Finally, when the largest shareholders are not individual entities but corporate body entities, subsidiaries are more willing to consider sequential investment.
