In this epidemiological study, 2121 school children(l050 boys and 1071 girls) that aged 9-16 years were surveyed. The subjects were randomly selected in cities of Jeonbuk, Korea and a questionnaire consists of 30 items including symptoms of craniomandibular disorders (CMD) and contributing factors of CMD were given to them. The author explained the definition of each item to subjects and they checked the answer of each item for themselves. The data were processed with regard to the prevalence of items and difference by Age or Sex with SPSS/PC+ package. The obtained results were as follows : 1. Among symptoms of CMD, joint pain by hard food chewing showed the highest rate of occurrence (40.8%), and locking sensation during mouth opening showed the lowest rate(5.4%). Symptoms with consistently increased rate of occurrence with age were joint sound, joint pain by hard food chewing, discomfort and/or spasm of jaw muscle. 2. With regard to prevalence of bad oral habit, about 12% of subjects had bruxism or clenching, respectively, but 35.1% had biting of pencil, ball point pen, 61.0% had lip biting or nail biting. 3. There were some items which always occurred more in one of boys and girls without regard to increase of age. In boys those were clenching first under stress, family and/or friend look like disregarding me, experience of shock or heavy force to jaw, and in girls nail biting, lip biting or chin in hand, getting cross without reason. 4. There was 64.2 % of total subject that have one or more symptoms of craniomandibular disorders.

해외자회사 CEO의 본사파견 여부가 해외자회사의 성과에 미치는 영향: 한국진출 외국인투자 제조기업을 중심으로

한경수,김미현,윤우진 한국국제경영학회 2019 國際經營硏究 Vol.30 No.2

본 연구는 국내에 진출해 있는 외국인투자기업 본사의 경영자 파견여부가 해외자회사의 성과에 미치는 영향에 대해 관찰하였다. 이에 더하여 연구개발 활동 수준, 기업 규모, 합작설립 여부와 같은 자회사 수준 변수들의 조절 효과를 규명해 보고자 하였다. 다국적 해외진출기업 총람을 통하여 획득한 338개의 외국인투자기업을 표본으로 2011년부터 2015년까지의 5개년도 패널자료를 분석한 본 연구의 실증 결과는 다음과 같다. 첫째, 국내진출 외 국인투자기업의 최고경영자가 본사에서 파견한 외국인일 경우 성과에 긍정적인 영향을 미치는 것을 확인하였다. 둘째, 외국인투자기업 해외 자회사의 연구개발 활동이 활발할수록 본사에서 파견된 최고경영자가 해외자회사의 성과에 미치는 영향력이 강화되는 것으로 나타났다. Based on the upper echelons perspective and the knowledge based view, we investigate the impact of CEOs from home on the performance of the foreign manufacturing subsidiaries in Korea. In addition, we also investigate the moderating roles of subsidiary level factors such as R&D expenditure, firm size, and entry mode (i.e. joint venture or not). Using the samples of 338 manufacturing subsidiaries, we conducted panel data analysis for five years from 2011 to 2015. The statistical results suggest that CEOs from home show the positive relationships with the performance of foreign subsidiaries. In addition, R&D expenditure positively moderated the relationships between CEOs from home and the performance of foreign subsidiaries.

1. Objectives The purpose of this study was to prove the correlation between risk factor of cardiovascular disease and Sasang Constitution and to investigate the effect of oxygen free radical on this correlation. 2. Methods We analyzed 129 patients who visited Cheonan oriental medical hospital from Apr 1, 2007 until May 31, 2007, for medical examination, which Includes Sasang Constitution examination, blood chemistry test and physical examination. And we classified their results into 4 groups based on with blood lipoprotein level and body mass index. 3. Results and Conclusions Mean of lipoprotein in blood was not significantly different among constitutions but with body mass index, was significantly higher in Taeumin than others. And count of dyslipoproteinemia was significantly higher in Taeumin group than soeumin. Therefore, according to our results, risk of cardiovascular disease was higher in Taeumin than other constitutions. Oxygen free radical did not have much effect on correlation between risk factor of cardiovascular disease and Sasang Constitution. However, there was some evidence in soeumin group, that oxygen free radical may have effect on origination of hyperlipidemia.

Purpose Local excision may be an another option for selected patients with markedly down-staged rectal cancer after preoperative chemoradiation therapy (CRT), and proper evaluation of post-CRT tumor stage (ypT) is essential prior to local excision of these tumors. This study was designed to determine the correlations between endoscopic findings and ypT of rectal cancer. Materials and Methods In this study, 481 patients with locally advanced rectal cancer who underwent preoperative CRT followed by surgical resection between 2004 and 2013 at a single institution were evaluated retrospectively. Pathological good response (p-GR) was defined as ypT ! 1, and pathological minimal or no response (p-MR) as ypT " 2. The patients were randomly classified according to two groups, a testing (n=193) and a validation (n=288) group. Endoscopic criteria were determined from endoscopic findings and ypT in the testing group and used in classifying patients in the validation group as achieving or not achieving p-GR. Results Based on findings in the testing group, the endoscopic criteria for p-GR included scarring, telangiectasia, and erythema, whereas criteria for p-MR included nodules, ulcers, strictures, and remnant tumors. In the validation group, the kappa statistic was 0.965 (p < 0.001), and the sensitivity, specificity, positive predictive value, and negative predictive value were 0.362, 0.963, 0.654, and 0.885, respectively. Conclusion The endoscopic criteria presented are easily applicable for evaluation of ypT after preoperative CRT for rectal cancer. These criteria may be used for selection of patients for local excision of down-staged rectal tumors, because patients with p-MR could be easily ruled out.

Recently, fire and explosion accidents caused by sparks scattered during welding and melting work in the work place where flammables are present. The causes of such fire accidents are mostly non-compliance with basic safety rules such as the removal of hazardous goods and the prevention of sparks scattering. It is strongly recommended to revise Industrial Safety and Health Act. This study analyzes the fire and explosion accidents in the work of firearms, such as welding and melting work, and analyzes the causes from a system perspective, and proposes an improvement plan for the system such as expanding the number of fire monitors, pre-approval of fire risk work, and intensifying fire prevention safety education. 최근 가연물이 있는 장소에서 용접·용단 작업 중 불꽃 비산 등으로 인한 화재·폭발사고가 빈발하고 있으며, 이러한 화재사고의 원인은 위험물 제거, 불꽃 비산방지 조치 등 기본적인 안전수칙 미준수가 대부분으로 산업안전보건법의 제도적인 보완이 필요하다. 본 연구에서는 국내 용접·용단 작업 등 화기작업에서의 화재·폭발 사고를 시스템적 관점에서 분석하고 그 결과를 반영하여 화재감시자 배치 확대, 화재위험작업의 사전승인, 화재예방 안전교육 강화 등 제도개선방안을 제안하였다.
