Exhaustion syndrome(虛勞) became broadly experienced symptoms in Korean population. In this work, we carried out a systematic literature review on exhaustion syndrome(ES) and chronic fatigue. We searched through the databases Koreanstudies Information Service System, Oriental Medicine Advanced Searching Integrated System, DataBase Periodical Information Academic for the articles published between 1994 and 2013, with the keywords 'exhaustion syndrome(虛勞)', 'consumption(虛損)', 'overexertion syndrome(勞倦)', 'fatigue', 'chronic fatigue' and 'degree of fatigue'. Among the first-run rough-searched 602 articles, we narrowed down the scope within the field of Oriental medicine (126 articles), and finally selected 28 articles appropriate to the intended research field; the selected articles were categorized by literature study(7 papers), clinical treatment (7), clinical diagnosis (5), treatment effects of herbal medicine (2), diagnosis in Sasang medicine and treatment effect of dry cupping therapy (2), and questionnaire-based diagnosis (5). We found that the overall research level on ES remained in the preliminary stages, and more efforts are needed in the field of terminology definition and standardization of diagnosis, and treatment efficacy validation beyond muscle fatigue. Finally, to develop reliable diagnostic devices on ES, we proposed a study design that included the development of objective ES diagnostic indicators and a clinical validation procedure.

Objectives: The hospital standardized mortality ratio (HSMR) has been widely used because it allows for robust risk adjustment using administrative data and is important for improving the quality of patient care. Methods: All inpatients discharged from hospitals with more than 700 beds (66 hospitals) in 2008 were eligible for inclusion. Using the claims data, 29 most responsible diagnosis (MRDx), accounting for 80% of all inpatient deaths among these hospitals, were identified, and inpatients with those MRDx were selected. The final study population included 703 571 inpatients including 27 718 (3.9% of all inpatients) in-hospital deaths. Using logistic regression, risk-adjusted models for predicting in-hospital mortality were created for each MRDx. The HSMR of individual hospitals was calculated for each MRDx using the model coefficients. The models included age, gender, income level, urgency of admission, diagnosis codes, disease-specific risk factors, and comorbidities. The Elixhauser comorbidity index was used to adjust for comorbidities. Results: For 26 out of 29 MRDx, the c-statistics of these mortality prediction models were higher than 0.8 indicating excellent discriminative power. The HSMR greatly varied across hospitals and disease groups. The academic status of the hospital was the only factor significantly associated with the HSMR. Conclusions: We found a large variation in HSMR among hospitals; therefore, efforts to reduce these variations including continuous monitoring and regular disclosure of the HSMR are required.

The diversification of Korean society with a large influx of migrant workers, international marriages, and international students calls for an attention to the importance of cultural competence of Library and Information Science sector in order to respond effectively and appropriately to the needs of immigrants who have diverse cultural backgrounds. In regard to these circumstances, this study is designed to develop the components of cultural competency needed by librarians. For this, this study collected its data through literatures review and interviews with librarians who are implementing services for immigrants in multicultural libraries and with experts who have experienced researches based multicultural services or involved with the management of multicultural families and migrant workers. As a result, the cultural competency components emerging from literatures review and interviews were divided into three parts ; multicultural attitude, multicultural knowledge and multicultural skills. And detailed components of three parts of cultural competency were specifically multicultural attitude, knowledge of multicultural groups, knowledge of multicultural services, development of collections, programs, and services, service delivery, language diversity, and professional education and workforce diversity.

Many changes lie ahead for Korea both domestically and internationally including opening of Busan New Port, more active Gwangyang Port as well as rapid growth of Shanghai Port and enhanced services and productivity at Shenzen Port. Compared to newer ports, container terminals in Busan Port possesses old equipment and facilities. Therefore, in order for Busan Port to maintain its service level and remain competitive, it needs to undergo remodeling to enhance productivity. Remodeling activities should be implemented on a continual basis by developing and applying new technologies such as those for gate system, berth system, yard system, and IT system In order to review the alternatives, we performed questionnaire survey and interview. From the result of analysis, we designed the application plan based on priority in remodeling, period of technology application, and direction for application.

When designing the size of a heavy maintenance shop for rolling stock, it is required to arrange buildings and facilities in the minimum site so as to improve the maintenance efficiency. However, the fluctuation rate (hereinafter "allowance rate") on which factors such as service and maintenance fluctuation should be applied when estimating the size of the maintenance shop has been used without verification. The objective of the study is to calculate a reasonable allowance rate and to review its appropriateness through the analysis of the facilities layout and process simulation to absorb the above elements into the staying time in the heavy maintenance shop. Since the working time, in this study, is assumed to be average working time, 10~20% was given to the standard deviation of working time in consideration of difference between workers, and possible allowance rate was drawn by analysis of the simulation results. In the future, it is required to optimize the size of the shop by applying appropriate allowance rate through scientific review of such factors as O&M plan, R/S reserve rate, capability of the shop, outsourcing rate, standard work amount, and so on.

Background: The infratemporal fossa (ITF) is an anatomical lateral skull base space composed by the zygoma, temporal, and the greater wing of the sphenoid bone. Due to its difficult approach, surgical intervention at the ITF has remained a heavy burden to surgeons. The aim of this article is to review basic skull base approaches and ITF structures and to avoid severe complications based on the accurate surgical knowledge. Methods: A search of the recent literature using MEDLINE (PubMed), Embase, Cochrane Library, and other online tools was executed using the following keyword combinations: infratemporal fossa, subtemporal fossa, transzygomatic approach, orbitozygomatic approach, transmaxillary approach, facial translocation approach, midface degloving, zygomatico-transmandibular approach, and lateral skull base. Aside from our Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) trial, there have been very few randomized controlled trials. The search data for this review are summarized based on the authors' diverse clinical experiences. Results: We divided our results based on representative skull base approaches and the anatomy of the ITF. Basic approaches to the ITF include endoscopic endonasal, transzygomatic, orbitozygomatic, zygomatico-transmandibular, transmaxillary, facial translocation, and the midfacial degloving approach. The borders and inner structures of the ITF (with basic lateral skull base dissection schemes) are summarized, and the modified zygomatico-transmandibular approach (ZTMA) is described in detail. Conclusions: An anatomical basic knowledge would be required for the appropriate management of the ITF pathology for diverse specialized doctors, including maxillofacial, plastic, and vascular surgeons. The ITF approach, in conjunction with the application of microsurgical techniques and improved perioperative care, has permitted significant advances and successful curative outcomes for patients having malignancy in ITF.

National parks are designated and managed for the purpose of preserving natural ecosystems, nature and cultural scenery, and promoting sustainable utilization in Korea. Since we designated Jirisan as the first Korean national park in 1967, we have now designated and managed 22 national parks. Because these national parks are the core protected areas of the nation and the ecological recreation center for the people, the interests of researchers related to national parks and citizens have steadily increased over the last 50 years. Especially, various natural science researches and social studies on national parks have been conducted with the launch of the Korea National Park Service in 1987, which is dedicated to national park management. However, we still lack research on national park research trends in Korea in spite of the increase in scientific research and public interest. It is important to know who and what institutes are leading national parks research, what research topics have been conducted, what kinds of researches are important in each national park, and how these researches relate to national park management policies. We propose a study to review the national parks related studies that have been carried out so far and identify the research trends. In the pilot study, we collected about 700 research papers on national parks published between 2002 and 2016 through the Korea Citation Index of Korean journals. We are analyzing the number of papers published, research institutes and research topics related to national parks. Analysis of these national park research trends will be necessary for efficient national park management and policy making for future generations.
