The 26^th World Congress of the International Association of Surgeons, Gastroenterologists and Oncologists (IASGO) was held in Seoul, Korea from September 8 to 10, 2016. In this congress, I gave a State-of-the-Art Lecture II entitled "Mesenteric Approach in Pancreatoduodenectomy." The ideal surgery for pancreatic head cancer is isolated pancreatoduodenectomy, which involves en bloc resection using a non-touch isolation technique. My team has been developing isolated pancreatoduodenectomy for pancreatic cancer since 1981, when we developed an antithrombogenic bypass catheter for the portal vein. In this operation, the first and most important step is the use of a mesenteric approach instead of Kocher's maneuver. The mesenteric approach allows dissection from the non-cancer infiltrating side and determination of cancer-free margins and resectability, followed by systematic lymphadenectomy around the superior mesenteric artery. This approach enables early ligation of the inferior pancreatoduodenal artery and total mesopancreas excision. It is the ideal surgery for pancreatic head cancer from both oncological and surgical viewpoints. The precise surgical techniques of the mesenteric approach are herein described.

다양한 사회복지와 보건의료 서비스를 체계적, 효율적으로 제공하고 관리할 수 있는 서비스 통합기능 창출 노력의 첫 단계로서, 서울시 은평구에서 각종 보건의료 및 사회복지 서비스를 이용하고 있는 생활보호 노인 및 장애인들을 시법 사례로 선정하여 사례관리 팀 접근법을 적용 실천해 보았다. 본 연구는 사례관리 팀의 구성과정 및 실천과점을 질적으로 분석하였다. 보건소의 가정도우미 및 담당 사회복지사, 방문간호사, 사회복지관의 재가복지담당 사회복지사 등으로 구성된 사례관리팀에서는 1) 클라이언트와 생활환경에 대한 정보 교환, 2) 각 기관에서 클라이언트에게 제공하고 있는 서비스 내용 파악, 3) 클라이언트가 필요로 하는 서비스 내용 파악, 4) 클라이언트 욕구에 대한 우선 순위 설정, 5) 단일 클라이언트에게 중복 실시되는 서비스 내용 조정, 6) 사례별 사례관리자의 지점, 7) 서비스 통합 또는 연계 체계 구축 시 고려해야할 문제점 등을 다루었다. 보건소나 사회복지관은 클라이언트에 대한 제한된 정보를 가지고 각 기관별로 부분적인 사례관리를 하여 단일 클라이언트에 대한 관리체계의 분열화가 이루어지고 있었는데 사례관리 팀을 운영함으로써 중복된 서비스 지원의 방지와 적절히 조정된 서비스를 제공할 수 있었다. 통합서비스의 효율적인 운영을 위해서는 서비스 통합 체계를 주도적으로 이끌 수 있는 주체가 중요한데 지역사회 단위에서 공공기관이 중심이 되어 민간기관의 참여와 협조를 이끌어 가는 것이 바람직한 것으로 생각된다.

Measuring the similarity of given samples is a key problem of recognition, clustering, retrieval and related applications. A number of works, e.g. kernel method and metric learning, have been contributed to this problem. The challenge of similarity learning is to find a similarity robust to intra-class variance and simultaneously selective to inter-class characteristic. We observed that, the similarity measure can be improved if the data distribution and hidden semantic information are exploited in a more sophisticated way. In this paper, we propose a similarity learning approach for retrieval and recognition. The approach, termed as LDA-FEK, derives free energy kernel (FEK) from Latent Dirichlet Allocation (LDA). First, it trains LDA and constructs kernel using the parameters and variables of the trained model. Then, the unknown kernel parameters are learned by a discriminative learning approach. The main contributions of the proposed method are twofold: (1) the method is computationally efficient and scalable since the parameters in kernel are determined in a staged way; (2) the method exploits data distribution and semantic level hidden information by means of LDA. To evaluate the performance of LDA-FEK, we apply it for image retrieval over two data sets and for text categorization on four popular data sets. The results show the competitive performance of our method.

Background: Case-based learning (CBL) is becoming an important approach for improving interprofessional collaboration education. Previous studies have examined learners' satisfaction with interprofessional education (IPE) in medical institutions. However, there are few studies on the implementation of university-led CBL interventions and their direct effects on learning outcomes. The aim of this study was to evaluate the effectiveness of CBL interventions on changes in the participants' perception and knowledge acquisition ability. Methods: The CBL approach consisted of team-based case-based learning, self-directed learning, and post-feedback. It was conducted as a single course for pharmacy students in their 5th year in a university setting. Changes in the participants' perceptions and self-assessments of competence levels were evaluated using survey responses. The effect of the CBL intervention on knowledge acquisition ability was directly evaluated using the exam score. Results: The majority agreed or strongly agreed that team-based case-based learning, and self-directed learning helped them to improve their knowledge and skills to a higher level and to increase the self-assessment of competency level. The average score of knowledge acquisition ability (average score of 75.0, p=0.0098) was significantly higher in the CBL intervention group than the lecture-based learning intervention group (average score of 52.0). Conclusion: The participants positively perceived that CBL intervention helped them to effectively improve their knowledge and the self-assessment of competency level. It also enhanced knowledge acquisition ability. These data, based on the survey responses, suggest that it is necessary to implement CBL interventions in a university-led single professional education.

Purpose: The aim of this study was to exam differences in awareness and ethical attitudes associated with Do-Not- Resuscitate (DNR) among emergency department's team. Method: The participants in this study were 402 emergency department's team working in the 41 hospitals. The data was collected by using "awareness measuring tool" by Kang (2003) and "ethical attitudes measuring tool" by Ko (2004) from May 1 to September 15, 2009. Collected data were analyzed by descriptive statistics, t-test, Pearson correlation coefficient using SPSS WIN 14.0 program. Results: 74.4% of subjects was responded that they had never been educated about DNR, but 73.9% of subjects was responded that they had experienced DNR in the emergency room. The majority of subjects responded that the patients and their families should make a decision about the DNR. There was a difference in an appropriate time for explanation of DNR among emergency department's team. There was a difference in ethical attitudes associated with Do-Not- Resuscitate among emergency department's team. Conclusion: For a professional and systematic approach to the problem, DNR guideline sufficient to elicit a social consensus is needed.

Purpose - To understand the growing interests in the professional temporary workforce, this study aimed to examine the different types of professional temporary workers and their different effects on creative performance. Design/methodology/approach - By sub-classifying professional temporary workers as boundaryless workers and transitional workers, this study developed propositions to provide comprehensive framework for directing meaningful topics for future research on professional temporary workers. Findings - This study suggested that two types of professional temporary workers may differ significantly in terms of their work efforts for getting approval or acceptance from the team members and for achieving creative contributions in teams. Specifically, drawing on expectance theory, social identity theory and resource-based theory, this study discussed the relationship between acceptance(task-oriented vs. relational-oriented acceptance), employment duration(short-term status vs. long-term status), contract security(volition being temporary worker) and creative performance for boundaryless workers versus transitional workers. Research implications or Originality - This study have implications for increasing our understanding of professional temporary workers by showing that creative performance may vary by employment types.
