Purpose: Despite the availability of molecular methods, identification of the causative virus in children with acute respiratory infections (ARIs) has proven difficult as the same viruses are often detected in asymptomatic children. Methods: Multiplex reverse transcription polymerase chain reaction assays were performed to detect 15 common respiratory viruses in children under 15 years of age who were hospitalized with ARI between January 2013 and December 2015. Viral epidemiology and clinical profiles of single virus infections were evaluated. Results: Of 3,505 patients, viruses were identified in 2,424 (69.1%), with the assay revealing a single virus in 1,747 cases (49.8%). While major pathogens in single virus-positive cases differed according to age, human rhinovirus (hRV) was common in patients of all ages. Respiratory syncytial virus (RSV), influenza virus (IF), and human metapneumovirus (hMPV) were found to be seasonal pathogens, appearing from fall through winter and spring, whereas hRV and adenovirus (AdV) were detected in every season. Patients with ARIs caused by RSV and hRV were frequently afebrile and more commonly had wheezing compared with patients with other viral ARIs. Neutrophil-dominant inflammation was observed in ARIs caused by IF, AdV, and hRV, whereas lymphocyte-dominant inflammation was observed with RSV A, parainfluenza virus, and hMPV. Monocytosis was common with RSV and AdV, whereas eosinophilia was observed with hRV. Conclusion: In combination with viral identification, recognition of virus-specific clinical and laboratory patterns will expand our understanding of the epidemiology of viral ARIs and help us to establish more efficient therapeutic and preventive strategies.

Smart application is developed in this paper by using an android-based platform to automatically determine the human emergency state (Lifesaver) by using different technology sensors of the mobile. In practice, this Lifesaver has many applications, and it can be easily combined with other applications as well to determine the emergency of humans. For example, if an old human falls due to some medical reasons, then this application is automatically determining the human state and then calls a person from this emergency contact list. Moreover, if the car accidentally crashes due to an accident, then the Lifesaver application is also helping to call a person who is on the emergency contact list to save human life. Therefore, the main objective of this project is to develop an application that can save human life. As a result, the proposed Lifesaver application is utilized to assist the person to get immediate attention in case of absence of help in four different situations. To develop the Lifesaver system, the GPS is also integrated to get the exact location of a human in case of emergency. Moreover, the emergency list of friends and authorities is also maintained to develop this application. To test and evaluate the Lifesaver system, the 50 different human data are collected with different age groups in the range of (40-70) and the performance of the Lifesaver application is also evaluated and compared with other state-of-the-art applications. On average, the Lifesaver system is achieved 95.5% detection accuracy and the value of 91.5 based on emergency index metric, which is outperformed compared to other applications in this domain.

본 연구는 기존의 필름 운영체계에서 PACS 운영체계로 전환 시 업무 변화에 따른 보건소 구성원 간의 인식을 조사하고 이들이 가지고 있는 새로운 업무에 대한 저항감을 줄여 새로운 시스템 도입에 적극적으로 적응할 수 있도록 하여 업무의 효율성을 높일 수 있는 기초 자료를 제공하고자 시행하였다. 연구기간은 2009년 6월1일부터 2009년 12월 16일까지이며 연구방법은 대전, 충남북에 소재하고 있는 필름운영체계에서 PACS 체계로 바뀐 보건소의 의사, 방사선사, 간호사, 기타 직종을 대상으로 하였으며 70부의 설문이 분석에 사용되었다. 임상적 유용성 인식은 방사선사(2.8) > 의사(2.7) > 간호사(2.4) > 기타(2.0)로 모든 직종이 향상된 것으로 인식하고 있었으며 PACS 가 필름시스템 보다 임상적으로 사용자 편리서, 접근 용이성 등이 모두 우수하며 임상적으로 유용하다고 답했다. 업무변화 및 효율성 인식은 방사선사(3.2) > 간호사(2.0) > 의사(1.988) > 기타(1.983) 순으로 직종별 차이를 보여 PACS 운영이후 업무가 효율적으로 변화되었다고 인식하고 있었다. 진료 및 근무환경 인식은 방사선사(3.6) > 의사(3.2) > 간호사(3.1) > 기타(3.0) 순으로 진료 및 근무환경이 향상되었다고 답했다. 교육적절성에 관한 인식은 기타(3.5) >간호사(3.0) > 의사(2.8) > 방사선사(2.5) 순으로 직종별 차이를 보였다. 적응 및 만족도 인식에서는 방사선사(2.9) > 기타(1.7) > 간호사(1.6) > 의사(1.5) 순으로 직종별 차이를 보였으며 PACS 운영이후 사용자의 적응도와 만족도가 높다는 것을 알 수가 있었다. 병원정보시스템의 핵심인 PACS 도입과 같은 보건소정보화 과정에서의 보건소 구성원의 인식을 알아본 결과, 임상적 유용성 인식, 교육 적절성에 관한 인식에서는 근무 년 수가 적을수록, 유용성이 높다고 했으며, 업무 변화 및 효율성 인식, 진료 및 근무환경 인식, 적응 및 만족도 의식에서는 근무 연수가 길수록 유용성이 높다고 인식하고 있었다. 성별에 따른 임상적 유용성 인식과 업무 변화 및 효율성 인식에서는 남자가 여자보다 유용하다고 인식하고 있었다. 연령별 차이에 따른 임상적 유용성 인식, 업무 변화 및 효율성 인식, 진료 및 근무 환경 인식은 40대 이상에서 높다고 인식하였다. PACS 도입으로 인해 보건소 구성원의 거부반응과 같은 저항감이나 부담감, 소극적 참여의지 등의 태도나 인식이 예상되었으나 연구 결과 대체적으로 모두 긍정적으로 인식하였으며 PACS가 보건소 구성원들에게 기존 필름체계를 대체할 수 있는 수단으로 유용하게 인식하고 있었다. 다만 본 연구결과는 향후 새로운 PACS 도입 시 성공적인 운영을 위해 직종에 따른 정보 제공 및 맞춤형 훈련 교육이 필요함을 시사하고 있다.

The early history of foreign Protestant missionaries in Korea has begun in the late 19th century, when they came to work as professionals such as teachers, medical doctors, etc. as the nation opened its door to western culture with the fall of national isolationism. Their records are considered crucial resources that enable us to shed new light on modern Korean history, politics, economy and society beyond mere religious value. Despite the recognition of such historic value of early missionary resources, however, there has been serious lacking of a systematic attempt to develop policies and plans for making it easy to collect, preserve and access the resources. Up to date, the records of early Protestant missionaries, in diverse forms of mission reports, books, periodicals, personal diaries, letters and photos, are scattered around various places, including their home country churches, governments, libraries, museums, research institutes and homes. Therefore, this research aims at providing basic resources on the archival status of early Protestant missionaries in Korea, needed for developing a sustainable and systematic digital archive system, through the investigation of early foreign missionaries' resources and in-depth interviews of experts. The study covers the period of 1800s to 1910, that is from the beginning of Protestant missionaries entering into Korea until the start of the Japanese annexation in 1910.

It has been generally recognized that the conventional rockfall protection nets have several problems to actual field application in the aspect of shock absorption, lack of pullout bearing capacities, and net damages. Because of the recognition, authors have tried to develop a new rockfall protection system consisted of shock absorption parts and hexagonal net configuration. In the previous research by the authors, the performance of the newly developed rockfall protection system has been investigated through the laboratory tests and the full-scale testing. In this study, subsequently, numerical analysis program is organized to make a confirmation of the structural stability and performance. For the correct design procedure of the hexagonal net system, it is essential to understand the various mechanical behavior of the entire system. It is also important to be reproduced the systematic characteristics of the system acquired by laboratory and full-scale testing by numerical analysis in order to carry out the numerical experiment to understand various mechanical behavior of the system. As a conclusion, the hexagonal net has better performance in mechanical and physical behavior compared with that of the rectangular net. Furthermore, due to the hexagonal net shows a good performance in aspect of the load distribution, it gives a good alternative in long-term management of the rockfall protection net.

Library and information research is often directed towards either the management of resources (e.g., the economics of resource management), their storage and retrieval (e.g., much information retrieval research), and the users of these resources (the whole area of information behaviour. However, the question that is less often asked is, "What research do librarians want to have carried out to help them in their work?" Clearly, some of the topics just mentioned will fall into the priority areas, but what do librarians actually perceive will be of use to them. There is a notion that a research-practice gap exists in the field and perhaps the reason for that is that researchers do not ask the practioners what research will be of value to them. To find an answer to this question on a global basis would, of course, be impossible - at least impossible without the level of funding that would be difficult to obtain from any source. However, it is possible to carry out research on a national level that could prove useful both to practitioners and to the library and information research community. This was the aim of a project, supported by the Svensk Biblioteksf$\"{o}$rening (Swedish Library Association), which was carried out in 2008/2009. Ideas on potential research projects were collected from librarians themselves, from discussion group archives and from the professional journals in a number of countries. These ideas were then grouped thematically and formed the basis of two rounds of a Delphi process to solicit the opinions of a panel of librarians in different sectors, recommended by their peers as 'expert' in their field. The Delphi process was concluded with a workshop involving a subset of the panel. This paper will report on the results of the investigation, which attracted a great deal of interest within the profession in Sweden, and will also reflect on issues that were ranked lowly in the investigation. For example, not a great deal of priority was given to topics relating to the development and use of technology: why was this? And would the same result be found in other countries? One major area of research interest was into the future of libraries and a topic of relevance here, especially for academic and research libraries, is the changing information behaviour of researchers: what, now, do researchers want of libraries? Clearly, technology is playing a role here, but digitized resources and the World Wide Web may not be the answer to every researcher's need. Research into libraries and research for libraries ought to figure largely in the profession's view of its aims, objectives and visions of the future: but for it to do so requires a recognition that the work will not be done unless researchers and practitioners come together to determine how to approach the future.

Many countries have provided support for research and development and implemented policies for Advanced Driver Assistance Systems (ADAS) for enhancing the safety of vehicles. With such efforts, the toll of casualties due to traffic accidents has decreased gradually. Korea has exhibited the lowest toll of casualties due to traffic accidents and is ranked 32nd in mortality among the 35 OECD members. Traffic accidents typically fall into three categories depending on the cause of the accident: vehicle to vehicle (V2V), vehicle to pedestrian (V2P), and vehicle independent. Most accidents are caused by drivers' mistakes in recognition, judgment, or operation. ADAS has been proposed to prevent and reduce accidents from such human errors. Moreover, the global automobile industry has recently been developing various safety measures, but on-road tests are still limited and contain various risks. Therefore, this study investigated the international standards for evaluation tests with regard to the assessment techniques in braking capability to cope with the limitations of on-road tests. A theoretical formula for braking force and a control algorithm are proposed, which were validated by comparing the results with those from an on-road test. These results verified the braking force depending on the functions of ADAS. The risks of on-road tests can be reduced because the proposed theoretical formula allows a prediction of the tendencies.
