목표는 한 분야에서 지속적으로 전문성을 성장시키는 주요한 심리적 원동력으로 작용한다. 본 연구에서는 국가경쟁력을 결정하는 주요 학문 분야 중 하나인 공학을 중심으로 이 분야 전문가의 다양한 목표 특성을 측정하는 "공학전문가 목표인식검사"를 개발하였다. 연구 참여자는 공학 분야에 종사하고 있는 공학전문가 90명, 공학전문가로서의 목표를 가지고 학업에 전념하고 있는 공과대학생156명을 포함한 총 246명이었다. 연구 결과, 본 검사에 포함된 네 가지 목표인식 특성인 목표 자율성, 목표 몰입, 목표 성취가능성, 그리고 목표의 내재적 가치를 측정하는 문항들은 적절한 문항내적일관성과 요인 적합도를 보이는 것으로 확인되었다. 준거타당도를 확인한 결과, 전문가로서의 목표인식과 관련성이 있을 것이라고 가정한 삶의 의미, 직업목표, 그리고 진로 확신과도 모두 유의한 정적상관을 보였다. 또한 전문가로서의 목표인식은 개인의 전문성이 발달함에 따라 증가하는 것으로 나타났다. 추가적으로, 전문가의 목표인식 수준에 영향을 미치는 개인적, 사회적 요인을 선정하여 목표인식과의 관련성을 살펴본 결과, 이들 요인들은 전문가로서의 목표인식과 유의미한 정적 상관을 갖는 것으로 확인되었다. 이러한 연구 결과는 본 연구를 통해 개발된 공학전문가 목표인식검사가 신뢰롭고 타당하다는 것을 보여준다. 마지막으로, 영역 특수적 목표검사로서 이 연구에서 개발한 공학전문가 목표인식검사의 의의와 이 검사를 활용하여 향후 어떤 후속 연구를 수행할 필요가 있는지에 관해 논의하였다. Goal functions as a major psychological motive to continue growing one`s expertise in a professional field. The purpose of this study was to develop and verify the validity and reliability of the goal questionnaire for engineering experts. The questionnaire measures diverse goal characteristics (i.e., goal autonomy, goal commitment, goal attainability and intrinsic value of goal) and factors affecting the goal perception. To validate the questionnaire, 246 participants (90 experts in professional engineering fields and 154 undergraduate students who have career goals as becoming a future engineering expert) were sampled. The results confirmed internal reliability and validity of the Goal Questionnaire for Engineering Experts. The questionnaire showed good criterion-related validity with three criterion measures of meaning in life, career goal, and career decision-making. In addition, the level of goal perceptions of experts increased along with the development of expertise. Also, diverse personal and social factors included in the questionnaire showed high positive correlations with the goal perceptions measured by the questionnaire. These results indicated that the Goal Questionnaire for Engineering Expert be a reliable and valid instrument for measuring the goal perceptions of engineering experts and personal and social factors affecting the perceptions. In sum, we discussed the importance of the questionnaire as one of the domain specific questionnaires and the future directions of studies using the questionnaire.

BACKGROUND: The annual incidence of venous thromboembolism (VTE) is increasing, and the treatment pattern of oral anticoagulants (OACs) has changed with introduction of new oral anticoagulants (NOACs). The aims of this study were to assess the annual incidence of VTE in a Korean population and the change of treatment pattern with availability of NOACs using a population-based database. METHODS: Using the Korean National Health Insurance Services database, we identified patients diagnosed with VTE between 2009 and 2016. The annual prevalence of VTE and clinical characteristics and treatment pattern were investigated. The annual incidence of VTE was calculated using direct and indirect methods using the estimated Korean population in 2009 as the reference. RESULTS: The annual incidence of VTE in Korean has increased yearly from 23.9 per 100,000 in 2009 to 42.2 in 2016. The overall rate of OAC prescription for VTE treatment increased from 55.9% to 68% in the same time period. The rate of initiation of NOAC treatment greatly increased, particularly from 2013 onwards, with a 20-fold increase from 2009 to 2016 (2.1% vs. 54.3%). CONCLUSIONS: The annual incidence of VTE in Korea increased by almost two-fold from 2009 to 2016. The rate of initiation of NOAC treatment has increased substantially since 2013, and these agents have surpassed VKAs as the anticoagulant of choice for VTE. This temporal pattern of OAC prescription is consistent with the current clinical guidelines, which indicate NOACs over the warfarin in patients with VTE.

This study is planned to investigate the attitude toward the safety and health management of contractor comparry. Under the contract based production system, all of activities including safety and health management in the contractor company are depended upon the contract. How to make contract influence the worker's health of contractor company. Work's health of contractor company can be protected by efforts of company of contract-out and contractor company, especially their safety managers. The modelling of the effective safety and health management system for contractor company should consider the need of safety manager of each company and employer of contractor company. Data is collected from safety managers of 3 contract out companies as electronic and electrical manufacturing industry and 55 safety managers, 57 employers of their contractor companies using self administered survey with structured questionnaire. The most of all respondents want to support from the contract out companies. The most important items supported from contract out company is the information based on the safety information network between each company. Safety manager and employer of contactor company also itemized safety education and training in the supporting system from contract out company. These results can be generalized to survey on the other industries.

Chul-Hyung Lee,Hyun Choi,Tae-In Kim,Jun Beom Kim,Sang Yeop Shin,Seung-Koo Rhee 대한견주관절의학회 2016 대한견주관절학회지 Vol.19 No.4

Background: The aim of study was to confirm the clinical effectiveness and results of wide and single anterior approach for fractures occurring along length of humerus. Methods: A total of 23 patients with humeral fracture were enrolled into our study who were able to participate in at least one year of follow-up. Seven patients had segmental comminuted humeral fractures and 16 patients had distal humeral fractures. We made various tractions of the muscles to expose the proximal and the middle third humerus between the biceps and brachialis and the distal humerus by partial splitting of lateral side of biceps through a single incision. Postoperatively, we measured the Mayo elbow performance index(MEPI). Results: we achieved bone union in all 23 patients. Solid union of the bone was achieved at an average 13.9 weeks. Postoperatively, two complications were observed screw loosening and nonunion. Revision surgery was performed in both patients. The patient with bone nonunion was treated using bone grafts. No postoperative infections or peripheral neuropathies were observed. At the final followup (average 20 months), we found that the average MEPI functional score of the patients was 91.7 points regardless of the fracture site. Conclusions: Our whole humerus with a single incision was effective for the treatment of segmental comminuted and distal fractures. we believe it is a useful alternative to preexisting methods of fracture fixation.

전역적 결정트리를 이용한 샷 경계 검출

신성윤(Shin Seong Yoon),문형윤(Moon Hyung Yoon),이양원(Rhee Yang Won) 한국컴퓨터정보학회 2008 韓國컴퓨터情報學會論文誌 Vol.13 No.1

본 논문에서는 프레임들의 차이값으로부터 카메라 브레이크에 의해 발생하는 큰 변화의 폭을 갖는 경계지점을 추출하는 전역적 결정트리를 이용하여 샷 경계를 검출하는 방법을 제시한다. 먼저 지역적 χ2 히스토그램과 정규화를 통하여 프레임 간 차이값을 계산하고, 다음으로 차이값간의 거리를 정규화를 통하여 계산한다. 계산된 차이값간의 거리를 바탕으로 전역적 임계치 거리를 계산하여 인접한 두 프레임들에 대한 거리값과 전역적 임계치 거리를 비교하여 샷 경계을 검출한다. 본 논문에서 제시한 전역적 결정트리를 이용하여 객체나 카메라의 움직임과 플래시 라이트와 같은 갑작스런 장면 변화를 쉽게 검출할 수 있다. This paper proposes a method to detect scene change using global decision tree that extract boundary cut that have width of big change that happen by camera brake from difference value of frames. First, calculate frame difference value through regional X2-histogram and normalization, next, calculate distance between difference value using normalization. Shot boundary detection is performed by compare global threshold distance with distance value for two adjacent frames that calculating global threshold distance based on distance between calculated difference value. Global decision tree proposed this paper can detect easily sudden scene change such as motion from object or camera and flashlight.

기존의 여러 동적 추천 시스템에서는 웹 페이지들 사이의 유사도와 로그 파일 안에 들어 있는 사용자들의 패턴을 이용하였기 때문에 연관된 페이지 뿐 아니라 단순히 순차적으로 연결되는 문서를 추천 페이지로 제공할 수 있었다. 본 논문에서는 기존의 방식에 각 페이지가 점유하는 시간의 분석을 더하려 한다. Data를 여러 분야로 나눌 수 있는 전자상거래의 특성을 이용하여 개개의 클러스터로 분류된 사이트들의 로그파일을 분석하여 점유시간의 크기와 무의미하게 보내어 지는 시간을 가중치를 주어 구별해내는 결과를 바탕으로 사용자가 주로 방문하는 연관성이 높다고 판단되는 웹 페이지를 추천하는 방법을 제안한다.
