Abstract The role of ports is rapidly increasing as international trade advances briskly, with globalization, industrialization and specialization at the same time. With the fast-growing role of ports, the workload of stevedore is also increasing, which leads to a high rate of industrial accident actually. As of 2010, ports – key national infrastructure – are important import-export gateway that accounts for the handling of more than 90% cargo. Industrial accidents occurred at this national infrastructure give rise to suspension of work, productivity loss, cost increase, loss of national image, etc. This national or personal loss may have enormously direct or indirect damage to ports. The purpose of this study is, First, to examine the real state of safety accidents and safety consciousness for harbor workers at Busan Port. Second, it is to determine the main factors that can have an effect on the safety performance for harbor workers. Lastly, it is to find out the effect on which safety climate and attitude of harbor workers have on their safety performance and verify it through empirical analysis. For this purpose, a survey was conducted on harbor workers at Busan Port Container Terminal and Bulk Terminal, For two weeks, from April 26, 2017 to May 12, 2017, 200 copies of questionnaires were distributed to them, of which 146 copies could be collected. SPSS 21.0 Program was used in date analysis, and frequency analysis was done for demographic characteristics, And then, Cronbach Alpha analysis and factorial analysis were conducted to verify the validity of measurement tool. With data proving reliability and validity, multiple regression analysis was done for hypothesis test. The result of this study is as follow : First, it turns out that, in terms of climate and safety performance, leadership, safety support, and cooperation have a positive effect on the safety performance. So, it is necessary to have a good strategy that can boost up safety performance through better communication among field workers and managers, free exchange of ideas and feedback, various support for safety, sense of morality and cooperation among coworkers. Second, in terms of safety attitude and safety performance, it turns out safety-oriented attitude has a positive effect on the safety performance. For better safety performance, stevedoring companies need to keep up the practice will and effort of having workers comply with safety regulations and procedures thereof. At first, it was thought that careless and cavalier attitude of workers might have a negative effect on safety performance, but empirical analysis shows their careless or cavalier attitude does not have significant effect on it statistically. This result shows that, although cargo working has a high risk of accidents, those accidents that are often occurred at come from safety ignorance that they have had usually. The result of this study shows the necessity of building up safety management system that can boost up the safety consciousness of workers, and coming up with how to improve safety performance. From a working-level standpoint, it can be an important implication.Abstract ⅳ 제1장 서 론 1 제1절 연구의 필요성 및 목적 1 제2절 연구의 방법 및 범위 2 제2장 이론적 배경 4 제1절 항만 하역 개요 4 제2절 산업재해 및 안전관리 20 제3절 부산항 항만하역 재해 현황 및 문제점 30 제4절 선행연구 43 제3장 연구 설계 48 제1절 연구모형의 설정 48 제2절 가설 설정 49 제3절 변수의 조작적 정의 및 측정도구 53 제4절 자료수집 및 분석방법 55 제4장 실증분석 56 제1절 연구표본의 특성 56 제2절 측정도구의 신뢰성 및 타당성 분석 61 제3절 가설 검정 64 제4절 분석 결과 66 제5장 결 론 67 제1절 연구의 요약 및 시사점 67 제2절 연구의 한계점 및 향후 연구방향 68 69 74Maste

Operative Treatment with Intramedullary Fibular Strut Allograft for Osteoporotic Proximal Humerus Fracture

Background: The purpose of this study was to investigate the clinical and radiological outcomes of locking plate fixation with fibular strut allograft to manage unstable osteoporotic proximal humerus fractures. Methods: We retrospectively reviewed 15 patients who underwent open reduction and locking plate fixation with fibular strut allograft for osteoporotic proximal humerus fracture between July 2011 and June 2015. For functional evaluation, we evaluated visual analogue scale (VAS) pain score, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) shoulder score, and active range of motion. For radiological evaluation, shoulder true anteroposterior (AP) and AP in 20° external rotation, as well as the axillary view were taken at two weeks, six weeks, three months, six months, and one year. And the neck-shaft angle was measured on the AP view in 20° external rotation view. Results: At the one-year follow-up, mean VAS pain score and all shoulder scores, including ASES score and UCLA shoulder score, exhibited satisfactory clinical outcomes. All patients obtained bone union between three and six months post-procedure. Moreover, the mean immediate postoperative neck-shaft angle was $138^{\circ}{\pm}4^{\circ}$, and at one-year follow-up, the neck shaft angle was $137^{\circ}{\pm}5^{\circ}$. There was no significant difference between the preoperative and postoperative values (p=0.105). Conclusions: For the unstable two-part and three-part osteoporotic proximal humerus fractures with medial calcar comminution, the use of fibular strut allograft with locking plate fixation was effective in maintaining the initial status of reduction and exhibiting the satisfactory functional and radiological outcomes.ope

Clinical outcomes and structural integrity of C-shaped rotator cuff tears after arthroscopic repair: comparison with crescent-shaped tears.

BACKGROUND: We aimed to describe a new C-shaped tear configuration, and to compare clinical outcomes and structural integrity between the C-shaped and the established crescent-shaped small to medium-sized rotator cuff tears after arthroscopic repair. METHODS: This retrospective study included 102 patients who underwent arthroscopic repair in a single-row fashion for small- to medium-sized rotator cuff tears of either C or crescent shape from March 2009 to June 2014. Visual analogue scale (VAS) pain score, subjective shoulder value (SSV), American Shoulder and Elbow Surgeon (ASES) score, and active range of motion (ROM) were evaluated for functional outcomes. Postoperative magnetic resonance arthrography (MRA) or computed tomographic arthrography (CTA) was performed 6 months postoperatively to assess structural integrity. RESULTS: After 2 years of follow-up, both groups showed no significant difference in VAS pain score, functional scores, or ROM, although the C-shaped tear group exhibited significantly inferior outcomes 3 months after surgery. There was no significant difference in the re-tear rate on follow-up MRA and CTA between groups A and B (24.4 vs. 19.7%, respectively; p = 0.570). The postoperative stiffness rate was significantly higher in the C-shaped tear group than that in crescent-shaped tear group only at 3-month follow-up point after surgery (26.8 vs. 9.8%, respectively; p = 0.024). CONCLUSIONS: Contrary to our hypothesis, there were no significant differences in functional outcomes and structural integrity between C-shaped and crescent-shaped small- to medium-sized tears 2 years after arthroscopic repair. However, C-shaped tears exhibited significantly worse clinical outcomes, including a higher postoperative stiffness rate than crescent-shaped tears in the early postoperative period at the 3-month follow-up point.ope

Fixation of Olecranon Fractures Using Plating System

Purpose: To evaluate the clinical and radiological outcomes of plate fixation for olecranon fractures which was difficult to be fixed firmly with tension band wiring alone. Materials and Methods: From 1995 through 2008, 20 patients who underwent plate fixation of an olecranon fracture were included in this retrospective study. According to the Mayo classification, there were 3 type IIA fracture, 7 type IIB, and 10 type IIIB fractures. Clinical evaluation was done based on radiographic union of olecranon and measurements of range of motion at last follow-up. Disability of the arm, shoulder and hand (DASH) score and Mayo Elbow Performance score was used for evaluation of functional recovery. Results: Union was achieved in 18 (90%) at an average of 5.6 months. The mean arc of elbow motion was 123° and the mean rotation arc was 81°. According to the MEPS, sixteen of twenty patients had a good or excellent outcome. The mean DASH score was 16.3. Most common complication was hardware irritation in 3 patients. Conclusion: Plate fixation is an effective treatment option for severe olecranon fracture pattern like comminuted fractures, Monteggia equivalent with unstable elbows and nonunions.ope

Medial Subluxation or Dislocation of the Biceps on Magnetic Resonance Arthrography Is Reliably Correlated with Concurrent Subscapularis Full-Thickness Tears Confirmed Arthroscopically

Background: The purpose of this study was to investigate the relationship between biceps medial subluxation/dislocation on the magnetic resonance arthrography (MRA) imaging and subscapularis full-thickness tear confirmed arthroscopically. We hypothesized that presence of a biceps medial subluxation or dislocation would strongly indicate a subscapularis full-thickness tear. Methods: A total of 432 consecutive patients who underwent arthroscopic repair for rotator cuff tears with/without subscapularis tears at our institute were retrospectively reviewed. The inclusion criterion of this study was preoperative MRA images taken within 6 months of arthroscopic repair. The presence of medial subluxation/dislocation was evaluated on the preoperative MRA images, and subscapularis tear was confirmed on arthroscopic examination. Results: Biceps subluxation/dislocation was identified in 46 of the 432 patients on MRA. Forty-five of these 46 patients also had a subscapularis full-thickness tear identified in arthroscopic examination. Among the 386 patients who did not have biceps subluxation or dislocation, 54 patients had a subscapularis full-thickness tear diagnosed arthroscopically. The presence of a biceps subluxation/dislocation could predict a subscapularis full-thickness tear with sensitivity of 45% (45/99), specificity of 99% (332/333), positive predictive value of 98% (45/46), negative predictive value of 86% (332/386), and accuracy of 87% (377(45 +332)/432). Conclusion: Medial subluxation/dislocation of the biceps on MRA images was highly associated with a concurrent subscapularis full-thickness tear which was confirmed arthroscopically. This association had 99% specificity and 98% positive predictive value. Therefore, if a biceps subluxation/dislocation is identified on MRA images, there is a high chance that a concurrent subscapularis full-thickness tear exists.ope

Serological studies on the specific antibodies against P-pili of uropathogenic escherichia coli

임상병리학과/석사[한글] 요로감염의 중요한 원인균은 장내 세균이며, 그 중에서도 특히 85% 이상의 요로감염은 대장균에 의한 것으로 알려지고 있다. 본 실험에서는 요로병뭔성 대장균의 중요한 병원성 결정인자 중 점막상피세포 부착능에 밀접한 관련이 있는 P-pili에 대한 항체 보유 여부를 혈청학적인 검사를 통하여 확인함으로써 요로감염중의 진단 가능성을 검토하고자 하였다. 비뇨기계 감염중으로 확진된 환자 60명의 혈청을 이용하여 유전자 재조합 대장균과 immunoblotting, 효소면역 측정법을 실시함으로써, 비뇨기계 감염중에서 높은 빈도로 분리되는 요로병원성 대장균의 p-fimbriae subtype의 분포를 조사하였으며, 요로감염증의 혈청학적인 진단으로 어느것이 우수한 지를 알아보았다. 본 실험에 사용한 유전자 재조합 plasmid를 보유한 각각의 대장균은 모두 MRHA형 pili로서 이것을 전기영동하고 가토에 요로병원성 대장균을 면역시킨 항혈청과 immunoblotting한 결과는 17KD-22KD범위에서 모두 강하게 반응하였다. 요로감염환자의 혈청을 이용한 immunoblotting결과 F7^^l : 34(56.7%), Fl3 : 30(50%), F7^^2 : 28(46.7%)순으로 양성을 보이는 혈청이 많아 국내에서 분리되는 요로감염성 대장균은 주로 F7^^l , F7^^2 , Fl3등의 P-pili를 보유하고 있을 것으로 생각되었다. 이와 같은 곁과는 효소면역 측정법을 실시한 결과에서도 동일하게 나타났다. 이러한 결과를 토대로 국내에서 분리빈도율이 높은 F7^^l , F7^^2 , Fl3 pili를 정제한 후 혼합하여 항원으로 이용한 효소면역 측정법의 특이도와 민감도를 조사하였던 바, 특이도는 92.6%, 민감도는 90%로 요로감염환자의 진단에 이용할 수 있는 유용한 방법으로 판단되었다. [영문] Escherichia coli is one of the most common etiological agents in urinary tact infection. An important virulence factor is the adHesive capacity of E.coli to uroepithelial cell, mediated by bacterial fimbriae. The Adhesion property has been regarded as an important virulence determinant in urinary tract infections. A total of 60 patients, who were diagnosed microbiologically as urinary tract infections, were examined by immunoblotting and enzyme-linked immunosorbent assay(ELISA).

Study on the moderating effect of religion on the relationship between constituents political orientation and conservative candidate selection

학위논문(석사)--서울대학교 대학원 :행정대학원 행정학과(정책학전공),2020. 2. 이승종.One can witness religions precepts conflicting with social·political issues nowadays compared to past. One can notice religion, especially Christianity colliding with social issues such as the Seoul queer culture festival, illegal abortions, discrimination prohibition laws, the new-right movements, opposition on Lady Gaga concert. When these conflicts arose, religious elite groups and believers often showed politically conservative stance. This study started from a simple curiosity asking Are people with religion really more likely to vote for conservative candidates on elections? The mission of this study is to find out what effect the religion variable has on constituents candidate selection. This study went forward from identifying simple independent effect of religion, tried to confirm constituents political orientations effect on conservative candidate selection, and verified religions moderating effect on the relationship between constituents political orientation and conservative candidate selection. This study used the constituents awareness survey on 2017, 19th Presidential Election of Republic of Korea which was organized by the Korean Social Science Data Center. The survey was requested by Republic of Korea National Election Commission and Korean Political Science Association. A statistical package STATA 14 was used to perform descriptive statistics analysis, correlation analysis, cross tabulation analysis, and logistics regression analysis. As a result, constituents political orientation showed significantly positive effect on conservative candidate selection, but religion variables did not show significant effect by themselves. However, the interactive variable of political orientation and Buddhist showed significantly positive moderating effect on conservative candidate selection. In other words, conservative constituent who is a Buddhist has higher possibility on voting for conservative candidate compared to conservative constituent who has no religion. This studys contribution to public administration·public policy studies can be classified into theoretical implications and practical implications. This studys theoretical implications are as follows. First, it verified which constituents political orientation is the most significant variable on candidate selection, and political orientation is more significant than constituents religions. Second, it confirmed which one has to approach different religions separately and religion can not be studied as bundled together. Third, this study has its significance which it set religion variable as a moderating variable compared to precedent researches which usually set religion as an independent variable or a control variable. Fourth, it confirmed Buddhists conservative political orientation. Based on this study, religions effect was light on the 19th Korean presidential election compared to other elections. However, the interaction between constituents political orientation and Buddhist showed positive moderating effect on selecting conservative candidate. Therefore, one can confirm Buddhists are the most conservative group, and one can infer which Buddhists are more conservative than Christians whom were found to be conservative on recent precedent studies. Fifth, it examined religion variable which was treated as an insignificant variable on voting behavior studies compared to variables such as constituents hometown or age group. This study has two practical implications. First, it gives practical insight to political parties and political research institutes. If they better understand the relationship between religions and candidate selection, they can establish effective election strategies which can broaden candidates support groups and better identify election results reasons. Second, this study confirmed the policy directivity which policy makers should possess. As religions effect on candidate selection gets studied definitely, policy makers and candidates should maintain religious neutrality more carefully than before. Furthermore, policy makers have to renounce policies which can be viewed as privilege toward certain religious groups and make effort for policies which can bring every religious groups and people with no religion together.최근 종교의 교리와 사회·정치적 이슈가 직접 충돌하는 사례가 과거에 비해 잦아지고 있다. 대표적으로 서울 퀴어 문화 축제, 낙태죄 폐지, 차별금지법 입법 반대 운동, 뉴라이트 운동, 레이디 가가 내한 공연 반대 등 종교, 특히 개신교와 사회적 이슈가 부딪히는 경우를 심심찮게 볼 수 있었다. 이러한 갈등이 있는 경우 종교 엘리트들과 신도들은 주로 보수적인 태도를 보였다. 본 연구는 종교를 가진 유권자가 실제로 보수 후보에게 투표하는 경우가 더 많은가? 라는 단순한 궁금증에서 출발하여 종교 변수가 유권자의 후보자 선택에 있어 어떠한 영향을 미치는지 분석하고자 하였다. 본 연구는 후보자 선택에 대한 종교의 독립적인 영향력 분석에서 나아가 유권자의 정치 성향이 보수 후보 선택에 미치는 영향력을 확인하고, 유권자의 정치 성향과 보수 후보 선택의 관계에 종교 변수가 가지는 조절 효과를 검증하고자 하였다. 본 연구의 분석 자료는 2017년 중앙선거관리위원회와 한국정치학회의 의뢰를 받아 실시한 한국사회과학데이터센터(KSDC)의 제19대 대통령 선거 관련 유권자 인식 조사의 통계 자료를 사용하였다. 분석은 통계 패키지 STATA 14를 이용하여 기술 통계 분석, 상관 분석, 교차 분석과 로지스틱 회귀 분석을 실시하고 변수 간 관계를 확인해 보았다. 분석 결과, 정치 성향이 보수 후보 선택에 유의미한 정의 영향을 보였으나, 종교 변수들은 독립적으로 유의한 영향력을 보이지 않았다. 하지만 정치 성향과 불교 신도 여부의 상호 작용항이 정치 성향이 보수 후보 선택에 미치는 영향에 대해 유의한 정의 조절 효과를 보였다. 즉, 보수적인 유권자가 불교 신도일 때 보수 후보에게 투표할 확률이 더 강하게 나타난다고 확인되었다. 개신교·천주교와 정치 성향의 상호 작용항은 통계적으로 유의한 영향을 보이지 않았다. 본 연구의 행정학·정책학적 함의는 크게 이론적 함의와 실용적 함의로 나뉜다. 본 연구의 이론적 함의는 다음과 같다. 첫째, 후보자 선택에 있어 유권자 정치 성향의 중요성 확인이다. 본 연구 결과를 통해 유권자의 정치 성향이 결국 후보자 선택에 있어 가장 중요한 변수라는 것을 검증하였으며 정치 성향이 종교보다 중요하다는 것을 확인하였다. 둘째, 불교 신도 여부만이 조절 효과를 보인 것을 토대로 종교 관련 연구를 시행할 경우 종교 집단별로 접근해야 하며 다른 종교 집단들을 묶어서 분석할 수 없다는 것을 확인했다. 셋째, 종교를 독립 변수 또는 통제 변수로 접근했던 기존 선행 연구에서 나아가 종교의 조절 효과를 탐색했다는 의의가 있다. 넷째, 불교 신도들의 보수 성향을 다시 확인하였다는 사실이다. 본 연구 결과로 미루어 보아 이전 선거와 비교하여 19대 대통령 선거에서는 종교의 영향력이 나타나지 않았다고 볼 수 있다. 그럼에도 불교 여부가 정치 성향과 후보자 선택에 정(+)의 조절 효과를 보인 것으로 미루어 보아 불교 신도들이 전통적으로 가장 보수적인 집단이었던 것을 재확인할 수 있었으며, 최근 선행 연구들에서는 보수적으로 나타났던 개신교 신도에 비해서도 더욱 보수적일 것이라고 추론할 수 있다. 다섯째, 기존의 출신 지역과 세대 중심의 투표 행태 분석에서 나아가 비교적 미진했던 선거에 있어 종교 변수의 영향력을 살펴보았다는 점에서 의미가 있다. 본 연구의 실용적 시사점은 크게 두 가지로 구분할 수 있다. 첫째, 정당 및 정치 관련 연구소 등이 활용할 수 있는 실용적 시사점이다. 정당이나 관련 연구소에서 종교와 후보자 선택 간의 관계를 더욱 깊게 이해한다면, 보다 효율적인 선거 전략 수립을 통한 후보자 지지 세력 확장 및 선거의 승패 원인 규명을 명확하게 하는 데 도움이 될 것으로 판단된다. 둘째, 정책 결정자로서 갖춰야 할 정책 지향성의 재확인이다. 후보자 선택에 대한 종교의 영향력이 명확히 규명될수록 정책 결정자 및 선출직 후보자로서는 종교적 중립성을 더욱 견지하는 자세가 더욱 요구될 것이다. 정책 결정자는 특정 종교에 혜택으로 비춰질 수 있는 정책을 지양하고 모든 종교인 및 무종교 인구를 아우를 수 있는 정책 수립을 위해 노력해야 한다.제 1 장 서 론 1 제 1 절 연구의 목적 및 필요성 1 제 2 절 연구의 대상 및 범위 3 제 2 장 이론적 배경 및 선행 연구 4 제 1 절 유권자의 후보자 선택 요인 4 1. 후보자 중심 요인 4 2. 유권자 중심 요인 6 제 2 절 종교와 정치 성향 9 제 3 장 연구 설계 및 분석 방법 15 제 1 절 연구 모형 및 가설 설정 15 1. 연구 모형 15 2. 가설 설정 17 제 2 절 연구 변수 18 1. 종속 변수 18 2. 독립 변수 18 3. 조절 변수 18 4. 통제 변수 19 제 3 절 분석 방법 및 분석 대상 21 1. 분석 방법 21 2. 분석 대상 21 제 4 장 연구 결과 25 제 1 절 기술 통계 분석 25 1. 종속 변수 25 2. 독립 변수 26 3. 조절 변수 27 4. 통제 변수 27 제 2 절 상관 분석 30 제 3 절 교차 분석 32 제 4 절 회귀 분석 35 1. 1단계 모형 분석 39 2. 2단계 모형 분석 40 제 5 장 결론 및 시사점 43 제 1 절 연구 결과 요약 43 제 2 절 연구의 함의 44 제 3 절 연구의 한계 및 향후 과제 46 참고문헌 48 Abstract 52Maste
