To identify nursing interventions performed by Chosunjok nurses in Yanbian using NIC. Methods: The sample consisted of 36 nurses working in 2 hospitals. The Nursing Interventions Use Questionnaire developed by the Iowa Intervention Project team was used for data collection. The instrument was translated to Korean using the method of back-translation. Results: Twenty-eight interventions were performed at least daily. Interventions in the Physiological: Basic domain were most frequently used at least daily. The most frequently used interventions was Positioning, followed by the interventions Pressure Ulcer Prevention, Intravenous (IV) Therapy, Hypothermia Treatment and Intravenous (IV) Insertion. The least frequently used interventions was Electronic Fetal Monitoring: Antepartum. Nurses working in special medical care units performed interventions most often, while nurses working in general surgical units performed them least. Nurses working in general medical, special medical and other care units performed interventions in the Physiological domain more often than the nurses working in general surgical units. Conclusion: Chosunjok nurses in Yanbian performed physiological interventions frequently. Further studies will be needed to compare interventions performed by nurses in two countries.

Detecting and capturing 3D human structures from the intensity-based image sequences is an inherently arguable problem, which attracted attention of several researchers especially in real-time activity recognition (Real-AR). These Real-AR systems have been significantly enhanced by using depth intensity sensors that gives maximum information, in spite of the fact that conventional Real-AR systems are using RGB video sensors. This study proposed a depth-based routine-logging Real-AR system to identify the daily human activity routines and to make these surroundings an intelligent living space. Our real-time routine-logging Real-AR system is categorized into two categories. The data collection with the use of a depth camera, feature extraction based on joint information and training/recognition of each activity. In-addition, the recognition mechanism locates, and pinpoints the learned activities and induces routine-logs. The evaluation applied on the depth datasets (self-annotated and MSRAction3D datasets) demonstrated that proposed system can achieve better recognition rates and robust as compare to state-of-the-art methods. Our Real-AR should be feasibly accessible and permanently used in behavior monitoring applications, humanoid-robot systems and e-medical therapy systems.

Digital Multimedia Broadcasting (DMB) is the mobile TV service based on a digital radio transmission system that provides high quality audio/video and other auxiliary data services. As users want to store the DMB content in their device to be consumed later or to be shared among users, a standardized format needs to be specified to guarantee the interoperability for the DMB contents for various devices. DMB AF (Application Format) specification defines a file format for DMB contents and services. It specifies how to combine the variety of DMB contents with associated information for a presentation in a well-defined format that facilitates storage, interchange, management, editing, and presentation of the DMB contents in protected, governed, and interoperable ways. In this paper we present our implementation of DMB AF as part of the development of DMB AF reference software. Our implementation of DMB AF is developed as the reference software for the standard specification that consists of a three applications: packager, media player, metadata browser and collection of supporting libraries used by the applications.

Purpose: In 2018, the Act on Decisions on Life-Sustaining Treatment for Patients in Hospice and Palliative Care or at the End of Life was implemented and the scope of official recognition for terminally ill patients was expanded. The purpose of this study was to investigate the decisions made by patients with end-stage liver disease about their life-sustaining treatment in a clinical setting. Methods: The subjects of this study were patients with end-stage liver disease hospitalized at a tertiary hospital in Seoul, Korea who wrote physician orders for life-sustaining treatment (POLST). Data collection was done using patients' electronic medical records, and a retrospective analysis of POLST was conducted. Results: Among 101 patients, 18.8% were female and 81.2% were male, and their mean age was 61.8 (±10.61) years. Sixty-three patients (62.4%) wrote their POLST by themselves. Three patients withdrew the POLST, of whom two did so for liver transplantation, and one did so for chemotherapy. Conclusion: This study shows that sufficient consideration of liver transplantation is needed for end-stage liver disease patients before making decisions on life-sustaining treatment. The self-determination of patients must be respected and effective guidelines are urgently needed.

Global warming awareness through energy conservation is growing due to the regulatory policies issued by governments and voluntary organization that established carbon emission limits. Transportation is one of the major contributors to carbon emissions. Bike will be simultaneously saving money, getting fit and helping to reduce global warming. Web design has been identified as a key factor for the acceptance and success of the websites and electronic commerce. The purpose of this research is to investigate the effective implementation of the proposed Analytic Hierarchy Process (AHP) technique on a bike case study whose company (Bike Company) is involved in web design for a critical component in the demonstration. Survey research used a variety of data collection methods, with the most common being questionnaires and interviews of some exporters. The research results reveal that the top five key success factors are Good reputation, Transaction security, Ease of use, Promotion, and Diversified choices, which provide the guidelines and directions for decision-makers to design effective websites in the current competitive business scenario. The major findings of this study are suggesting that Internet marketing channels are securing the company's relevance, together with paving the way for methods to increase web traffic.

Segmentally erected prestressed concrete box girder bridges have been widely used in Korean high speed railway. Segmental erection has been accomplished along the longitudinal direction and across the depth of cross section. The cross section is similar to a composite cross section, composed of old and new segments. Because these segments have different time-dependent creep and shrinkage properties, a stress redistribution takes place during the construction period. It is the main objective in this research to investigate this behavior. An actual bridge was instrumented with 96 vibrating wire embedded type strain gauges, 6 electronic type steel strain gauges, and 75 thermocouples. Two span continuous high speed railway bridge was selected. Two points of importance, such as the midpoint of the first span and the point of interior support, along the span of the girder were chosen to monitor the time dependent behaviors for an extended period of time. The data collection was starting just after concrete girder were cast and is still going on. According to the measured results, the strain distributions across the depth of the section at midspan and interior support were not continuous and the important redistribution of stresses takes place. Thus, rational design of prestressed concrete composite box girder bridges need.

This study evaluated the engineering students' ethical sensitivity to an AI emotion recognition robot scenario and explored its characteristics. For data collection, 54 students (27 majoring in Convergence Electronic Engineering and 27 majoring in Computer Software) were asked to list five factors regarding the AI robot scenario. For the analysis of ethical sensitivity, it was checked whether the students acknowledged the AI ethical principles in the AI robot scenario, such as safety, controllability, fairness, accountability, and transparency. We also categorized students' levels as either informed or naive based on whether or not they infer specific situations and diverse outcomes and feel a responsibility to take action as engineers. As a result, 40.0% of students' responses contained the AI ethical principles. These include safety 57.1%, controllability 10.7%, fairness 20.5%, accountability 11.6%, and transparency 0.0%. More students demonstrated ethical sensitivity at a naive level (76.8%) rather than at the informed level (23.2%). This study has implications for presenting an ethical sensitivity evaluation tool that can be utilized professionally in educational fields and applying it to engineering students to illustrate specific cases with varying levels of ethical sensitivity.

RFID(Radio Frequency Identification)란 정보를 읽거나 쓰기 위한 반도체 칩을 내장하고 정보의 전송을 위해 안테나를 사용하는 무선주파수 시스템을 말한다. 이렇게 전송된 정보를 수집 및 여과하는 미들웨어, RFID코드와 관련된 정보를 저장하고 있는 객체정보서버, 이력정보가 저장된 위치정보를 가진 객체이력서버, 코드와 관련된 물품정보가 있는 서버의 위치를 알려주는 RFID 검색서비스 등이 RFID 서비스 네트워크를 구성한다. 따라서 검증 실험에서와 같이 측정 분석 결과는 리더 간 전파 간섭이 발생하지 않기 위해서는 안테나 단에서 수신되는 power 레벨이 최소한 -55dBm을 유지해야만 전파 간섭이 발생하지 않을 것으로 생각되고, 안테나와 테그의 인식 거리는 최대 7m가지도 가능하지만, 원활한 인식을 위해서는 3-4m이내에서 사용되어야 바람직 할 것으로 생각된다.

The IARC Monographs Programme on the Evaluation of Carcinogenic Risks to Humans has reviewed, summarized and evaluated 869 environmental agents and exposures as oj June 2000. This large collection includes all relevant published epidemiological data on cancer in exposed humans and results of bioassays for carcinogenicity in experimental animals. Since 1986. cancer data have been systematically supplemented by summaries of other toxicological data that are relevant to assessments of carcinogenic hazard. These include summaries qf genetic and related effects of chemicals. which have been prepared as Genetic Activity Profiles (GAP) by the U.S. EPA in collaboration with IARC. As the Mono-graphs have proved increasingly valuable and influential worldwide. they have evolved into an encyclopedia on environmental carcinogenic risks to humans. However. the Monographs have historically been prepared only as printed books with limited distribution. and the Monographs Programme has needed to adjust to expectations oj wider availability. Since 1998 the evaluations and summaries have been globally accessible by Internet from IARC (http://www.iarc.fr) and the GAP profiles by Internet from EPA (http://www.epa.gov/gapdb/). with the two web sites linked. Improved EPN/ARC GAP database and software. GAP2000. now link GAP profiles directly to the appropriate IARC web pages for summaries of evaluations of a given compound and its overall IARC classification. During the year 2000. by means of optical character recognition (OCR) technology the entire series of IARC Monographs is being converted to an electronic version. The first edition is now available commercially in CD-ROM format and will soon become available on-line at .
