Recently, the Specified streets are designated in the many cities. The specified street is formed naturally by gathering the same type of shops in the same street. The purpose of the specified street is to enhance and to make more lively the characteristics of the street. These specified street has the network consisted of elements, namely shop owner, the authorities, the consumers, etc. In the beginning, we examined how specific streets are made and composed in Seoul and Inchun: the street of the culture, the rodeo, and the furniture. As it turned out, the formation of the network organization in the specific streets showed that how much it is important that it impacted managing. The members of network work together for improvement of the street by negotiation and cooperation. In that process, the street scenery is also improved. This network promotes the spontaneous participation of the members of the affair. In the result of that, the effect of the network is a core which is one of the factors managing and improving specific street. A continuous examination of the more study would strengthen the importance of the network in changing specific street construction.

이현재,손지언,,홍영습,,이영일,예병진,유창훈,정갑열,김상훈,임형준,장은철,김정만,김준연 大韓産業醫學會 2006 대한직업환경의학회지 Vol.18 No.2

목적: 석면에 노출된 근로자에서 석면관련 폐질환의 양상을 분석하고 진단에 있어 HRCT의 유용성을 연구하여 석면에 대한 의학적 감시프로그램의 개발에 기여하고자 하였다. 방법: 석면에 직접 노출되는 작업자 68명과 간접 노출되는 작업자 94명 등 총 162명에 대해 OSHA 석면 표준, 의학적 감시 프로그램에 따라 단순 흉부방사선검사, 폐활량검사 및 우리나라 실정에 맞게 일부 수정한 의학적 설문지를 통해 면접조사의 방식으로 환자에 관한 정보를 수집하였으며, 자료의 신뢰성을 확보하기 위하여 면접조사는 1달 이상의 기간을 두고 2차례에 걸쳐 실시된 후 확인, 수정하였다. 또한, 석면관련 폐질환을 확진하기 위하여 HRCT를 추가적으로 실시하였다. 결과: HRCT결과 석면관련 폐질환의 유병율은 162명의 근로자중 17명으로 10.5%였는데, 직접 노출군에서 10명 (14.7%), 간접 노출군에서 7명 (7.4%)이었다. HRCT와 비교할 때 단순 흉부방사선검사의 민감도와 특이도는 각각 70.6%와 98.6%이었고, 양성 예측도와 음성 예측도는 각각 85.7%와 96.6%으로, HRCT는 단순흉부방사선검사에 비해 민감도가 높아 초기 석면관련 폐질환을 진단하는데 효과적이었다. 석면관련 폐질환의 진단에 있어 HRCT와 폐활량검사 사이에 유의한 관련성이 관찰되었다. HRCT 결과 석면관련 폐질환의 유무와 의학적 설문조사 결과의 빈도분석을 실시한 결과, 유의한 변수는 작업기간, 흡연량, 호흡기질환의 과거력, 기침, 호흡곤란이었다. 결론: HRCT는 석면관련 폐질환의 진단에 있어 단순 흉부방사선검사와 비교하여 민감도가 높아 초기 진단에 유용하므로 단순 흉부방사선선검사 결과 석면관련 폐질환소견을 보일 때뿐만 아니라, 정상소견을 보이더라도 폐활량 검사결과와 근무력, 흡연력, 호흡기질환의 과거력, 기침, 호흡곤란 등의 호흡기 증상을 참고하여 HRCT검사를 고려해야 한다. 또한, 본 연구에서 관련성이 없었던 요인들에 대해서도 향후 연관성을 규명하는 광범위한 전향적 연구가 필요하다. Objectives: This study was carried out to improve the medical surveillance program of workers exposed to asbestos by examining the usefulness of High Resolution Computed Tomography (HRCT) in the diagnosis of asbestos-related lung disease. Methods: The study subjects comprised 162 workers in a ship-repairing yard, 68 of whom had been directly exposed to asbestos and 94 indirectly exposed. The 'Occupational Safety & Health Administration (OSHA) asbestos standard, medical surveilance program' and HRCT were conducted to analyze the aspects of the asbestos-related lung disease. The OSHA asbestos standard, medical surveilance program consists of simple chest x-ray, spirometry and medical questionnarie. Results: Seventeen (10.5%) of the 162 subjects, 10 (14.7%) directly exposed and 7 (7.4%) indirectly exposed, revealed asbestos-related lung disease on HRCT. The sensitivity and specificity of simple chest x-ray for asbestos-related lung disease were 70.6% and 98.6%, and the positive and negative predictive values were 85.7% and 96.6% respectively, as compared with HRCT, HRCT was an effective diagnostic tool especially to detect early asbestos-related lung disease. The study results indicated a relative significant association between the results of spirometry and HRCT. The variables significantly associated with asbestos-related lung disease on HRCT were work duration, smoking history (pack-years), past history of respiratory disease, cough and dyspnea. Conclusions: In the diagnosis of asbestos-related lung disease, HRCT should be considered not only for workers with positive findings on simple chest x-ray, but also workers with specific findings on spirometry, occupational history, smoking history, and past history of respiratory disease, or with respiratory symptoms such as cough and dyspnea.

Alveolar bone grafting is an essential component of successful surgical rehabilitation in many common cleft deformities. Primary alveolar bone grafting is defined as alveolar bone grafting which takes place before eruption of the primary dentition or before 1 years of age. The major objective in primary alveolar bone grafting is to prevent significant maxillary segmental collapse and arch disturbances. If severe, this can make secondary rehabilitation difficult, costly, and protracted. Such early stabilization may eliminate or, at least, decrease the amount of orthodontic arch expansion required during the transitional dentition period. Furthermore, early obliteration of alveolus fistulae improves speech and dental hygiene. It is critical that abutting maxillary segmental alignment be achieved(generally when the patient is 8 to 10 months of age) before grafting. Otherwise, the amount of dissection necessary to develop mucosal flaps for bone graft coverage will be more extensive, thus risking increased scar formation with potential adverse effects on growth. We report a preliminary result of 4 cases of primary alveolar bone graft using rib bone, performed by limited dissection and onlay graft technique at 8 to 10 months of age. They showed satisfactory clinical results especially in terms of growth up to now.

목적: 이 연구의 목적은 처음 정상 혈압으로 응급실을 내원한 비정맥류성 상부위장관 출혈 환자에서 Glasgow-Blatchford 점수와 내시경 전 Rockall 점수가 24시간 이내에 발생하는 저혈압을 예측할 수 있는가이다.대상 및 방법: 2011년 1월부터 2013년 12월까지 서울아산병원 응급의료센터로 내원한 상부위장관 출혈 환자를 대상으로 후향적인 연구를 시행하였다. 대상이 되는 환자군을 24시간이내 저혈압 발생 여부에 따라 두 군으로 나누었으며, 인구학적 특성, 기저 질환, 혈액 검사 결과를 비교하였다. 각 환자의 Glasgow-Blatchford 점수와 내시경 전 Rockall 점수를 구하고 저혈압 발생의 예측도를 평가하였다.결과: 연구 기간 동안 비정맥류성 상부위장관 출혈로 내원한 환자들 중 초기 정상혈압을 보인 환자는 747명이었다. 이 중120명(16.1%)이 응급실에 내원한 지 24시간 이내에 저혈압이 발생하였다. 저혈압이 발생한 환자군과 그렇지 않은 군 간의 Glasgow-Blatchford 점수와 내시경 전 Rockall 점수의 중간 값은 통계적으로 차이를 보였다(각각 8점 vs. 10점, 2점 vs.3점, p<0.001). ROC 분석 결과, 두 점수 간 곡선 아래 면적은 각각 66%, 64%로 24시간 내에 저혈압 발생에 대한 예측력은 유의한 차이가 나지 않았다.결론: Glasgow-Blatchford 점수와 내시경 전 Rockall 점수는 비정맥류성 출혈 환자의 저혈압 발생을 예측할 수 없으며, 다른 점수 체계 개발이 필요할 것으로 보인다. Background/Aims: The aim of this study was to identify the ability of Glasgow-Blatchford score (GBS) and pre-endoscopic Rockall score (pre-E RS) to predict the occurrence of hypotension in patients with non-variceal upper gastrointestinal bleeding who are initially normotensive at emergency department.Methods: Retrospective observational study was conducted at Asan Medical Center emergency department (ED) in patients who presented with non-variceal upper gastrointestinal bleeding from January 1, 2011 to December 31, 2013. Study population was divided according to the development of hypotension, and demographics, comorbidities, and laboratory findings were compared. GBS and pre-E RS were estimated to predict the occurrence of hypotension.Results: A total of 747 patients with non-variceal upper gastrointestinal bleeding were included during the study period, and 120 (16.1%) patients developed hypotesion within 24 hours after ED admission. The median values GBS and pre-E RS were statistically different according to the occurrence of hypotension (8.0 vs. 10.0, 2.0 vs. 3.0, respectively; p<0.001). In the receiver operating characteristic curve analysis of hypotension development, the area under the curve of GBS and pre-E RS were 66% and 64%, respectively. The sensitivity and the specificity of GBS using optimal cut-off value were 81% and 46%,respectively, while those based on the pre-E RS were 74% and 46%, respectively.Conclusions: GBS and pre-E RS were both not sufficient for predicting the occurrence of hypotension in non-variceal upper gastrointestinal bleeding. Development of other scoring systems are needed.(Korean J Gastroenterol 2016;67:16-21)

Establishment of Growth Strategies for International Construction Firms by Exploring Diversification-Related Determinants and Their Effects

Sung, Yoo-Kyung,Lee, JeeHee,Yi, June-Seong,Son, JeongWook American Society of Civil Engineers, Engineering M 2017 Journal of management in engineering Vol.33 No.5

<P>Many construction firms have promoted diversification as an important growth strategy. However, previous studies on diversification performance show conflicting results on the correlation between diversification and business performance. Although this is partly because of the different theoretical perspectives of researchers, it is mainly derived from the differences between the various industries and their market environments. Thus, this study considers the influencing factors, such as construction market environment, company size, and business segment, which affect the relationship between diversification and business performance to analyze the relationship between international business diversification and the business performance of international contractors. Based on the data released in the Engineering News Record and financial reports, varied statistical exploration including correlation and clustering analysis were performed to derive effective strategies grounded in the relationship between diversification level and business performance. According to the analysis results, the international business diversification levels showed a clear positive correlation with sales revenue, whereas business diversification, profit margin, and current ratio did not show a strong correlation; rather, a higher level of diversification tended to weaken the profit margin and current ratio. From the result showing the correlation between diversification and business performance derived from the clustering analysis, it was found that although diversification is essential to facilitate growth in the size of the company, it can reduce the profitability and stability of a diversified company. Ultimately, this study will provide appropriate and effective business strategy guidelines for international contractors endeavoring to expand their international markets.
