  • The purpose of this study was to investigate the knowledge, attitudes and behaviors of radiation protection in operating room and intensive care unit nurses. The Participants for this study consisted of 240 nurses working in operating rooms and intensive care units of 7 general hospitals located in Busan, South Korea. The data were collected from Feb. 15 to Feb. 29, 2016. The study results were as follows. First, 72.9% of the nurses had never been educated for radiation safety. Second, the mean score of knowledge for radiation protection was 9.21. The knowledge score of radiation safety educated nurses is higher than uneducated of nurses(t=-5.67, p<.001). Third, The mean score of attitude towards radiation protection was 41.80. The attitude score of radiation safety educated nurses is lower than uneducated of nurses(t=0.02, p<.030). Fourth, the mean score of behavior for radiation protection was 32.57. The behavior score of radiation safety educated nurses is higher than uneducated of nurses(t=0.35, p=.001). Consequently, it was found that nurses had lack of the radiation safety education. Overall knowledge and behavior towards radiation protection was low. Therefore, it is necessary to raise awareness of radiation protection and to educate, manage, and improve processes to increasing compliance with protective measures against radiation.

  • The aim of this study is providing basic data to design successful in-service training program for teacher librarians by analyzing their preference on subjects of customized intensive programs for indicators of teacher expertise development. According to the survey, teacher librarians seem to regard training subjects such as Reading Education and Information Literacy Instruction related educational information services as core jobs and prefer developing instructional contents and materials. Under the levels of school it seems that teacher librarians in the elementary school are interested in programs for library activation, management of volunteers, analyses of users' needs and curricula, evaluations of user instruction and information literacy instruction. Older teacher librarians favor an understanding of metadata, building and supporting information system and instruction. Therefore, training subjects for teacher librarians should be formed by linking strategies between school library instruction and subject curricula. And in terms of the method of training, case studies and practical training might be better than lectures based on the theory.

  • Purpose: This study aims to develop a self-reflection program for nurses who have experienced the death of pediatric patients in the intensive care unit and to evaluate its effectiveness. Methods: The self-reflection program was developed by means of the following four steps: establishment of the goal through investigation of an initial request, drawing up the program, preliminary research, and implementation and improvement of the program. The study employed a methodological triangulation to evaluate the effectiveness of the program. Participants were 38 nurses who had experienced the death of pediatric patients (experimental group=15, control group=23); they were recruited using convenience sampling. The self-reflection program was provided over 6 weeks (6 sessions). Data were collected from April to August, 2014 and analyzed using t-tests and content analysis. Results: The quantitative results showed that changes in personal growth (t=-6.33, p<.001) and burnout scores (z=-2.76, p=.005) were better in the experimental group compared to the control group. The qualitative results exhibited two themes, namely "personal growth" and "professional growth", and ten sub-themes. Conclusion: The self-reflection program developed by this study was effective in helping nurses who had experienced the death of pediatric patients to achieve personal growth through self-reflection, and it was confirmed that the program can be applied in a realistic clinical nursing setting. Furthermore, it can be recommended as an intervention program for clinical nurses.

  • Purpose: The aim of this study was to verify the effects of daily 2% chlorhexidine gluconate (CHG) bathing on the acquisition of multidrug-resistant organisms (MDRO) and healthcare-associated infection (HAI) in a medical intensive care unit (MICU). Methods: The study was a randomized controlled group posttest only design, involving 91 patients in MICU at a tertiary hospital (47 patients in the experimental group and 44 patients in the control group). The 2% CHG bathing was performed daily according to bathing protocol to the patients in the experimental group, and traditional bath was performed every three days to those in the control group. Fisher's exact test and x2 test were used to analyze the data. Results: MDRO were found in 6 patients of the experimental group and in 15 patients of the control group. The difference was statistically significant (p= .016). HAI occurred in 2 patients of the experimental group and in 7 patients of the control group. The difference was not statistically significant (p= .084). Conclusion: The results confirmed that daily bathing with CHG was effective in reducing the incidence of MDRO acquisition. Therefore, it is expected that daily bathing with CHG will be used as an effective nursing intervention to reduce the incidence of MDRO acquisition.

  • Purpose - Intra-industry trade of agricultural products can eliminate the disadvantage of Korea's traditional agriculture and improve its lack of comparative advantage. The main purpose of this paper is to measure the level and index of intra-industry trade of Korean agricultural products and to explore the spatial dependence and spillover effect associated with this type of trade. The main factors influencing intra-agricultural trade are analyzed from two perspectives: the population and the classification of agricultural products. Design/methodology - First, the level of intra-industry trade of Korean agricultural products is measured. Second, to obtain a more accurate estimate of the influence of various factors, and based on two types of weight matrices, a spatial econometric model is constructed from two aspects: population and classification of agricultural products. The status and the factors influencing intra-industry trade are also studied. Findings - It is concluded that there is a positive spatial correlation between Korea's intra-industry trade in agricultural products and that of its trading partners. The spatial spillover effect of this type of trade is verified by using the spatial autoregressive model (SAR). Labor-intensive agricultural products are found to have a positive spillover effect on intra-industry trade, while land-intensive products do not have a significant effect. Originality/value - In this paper, the two types of agricultural products are meticulously distinguished, and the spatial effect of the intra-industry trade of agricultural products as well as the influence of various factors are analyzed. In addition, the accuracy of the estimation of the coefficients of the factors by using the spatial econometric model is higher than that of the ordinary panel data model.

  • The Active Appearance Model (AAM) is a class of deformable models, which, in the segmentation process, integrates the priori knowledge on the shape and the texture and deformation of the structures studied. This model in its sequential form is computationally intensive and operates on large data sets. This paper presents another framework to implement the standard version of the AAM model. We suggest a distributed and parallel approach justified by the characteristics of the model and their potentialities. We introduce a schema for the representation of the overall model and we study of operations that can be parallelized. This approach is intended to exploit the benefits build in the area of advanced image processing.

  • The authorized form is called the heading must be unique and consistent. Without both uniqueness and cosistency, retrieval from the bibliographic database will not be optimal and in some cases may even be impossible. But the authority control is extremely expensive, because it is labour-intensive and dependent on professional investigation and judgement. In fact, it is by far the most expensive function in all of bibliographic control. The processes used to determine the form of access points. maintain. use. and evaluate very accurate authority records reduce the efficiency to generate or merge bibliographic items without modification from any national level bibliographic utilities as well as individual library. In this paper non-authority control system was suggested to solve the disadvantages of authority work. The apparent advantages of the non-authority control system are it is easy to determine the heading, input the bibliographic data. integrate the access points into an existing file, and generate and merge bibliographic data without modification. In addition, non-authority control system can be transmitted into online information retrieval system conducted with a mixture of controlled vocabularies and natural language.

  • Due to the paradigm of open science and advanced digital information technology, data sharing and re-use have been actively conducted and considered data-intensive in a wide variety of disciplines. This study aims to investigate the intellectual structure portrayed by the research products re-using the data sets from ICPSR. For the purpose of this study, a total of 570 research products published in 2017 from the ICPSR site were collected and analyzed in two folds. First, the authors and publications of those research products were analyzed in order to show the trends of research using ICPSR data. Authors tend to be affiliated with university or research institute in the United States. The subject areas of journals are recognized into Social Sciences, Health, and Psychology. In addition, a network with clustering analysis was conducted with using co-word occurrence from the titles of the research products. The results show that there are 12 clusters, mental health, tabocco effect, disorder in school, childhood, and adolescence, sexual risk, child injuries, physical activity, violent behavior, survey, family role, women, problem behavior, gender differences in research areas. The structure portrayed by ICPSR data re-uses demonstrates that substantial number of studies in Medicine have been conducted with a perspective of social sciences.

  • Purpose: In this study a system dynamics methodology was used to identify correlation and nonlinear feedback structure among factors affecting unplanned extubation (UE) of ICU patients and to construct and verify a simulation model. Methods: Factors affecting UE were identified through a theoretical background established by reviewing literature and preceding studies and referencing various statistical data. Related variables were decided through verification of content validity by an expert group. A causal loop diagram (CLD) was made based on the variables. Stock & Flow modeling using Vensim PLE Plus Version 6.0b was performed to establish a model for UE. Results: Based on the literature review and expert verification, 18 variables associated with UE were identified and CLD was prepared. From the prepared CLD, a model was developed by converting to the Stock & Flow Diagram. Results of the simulation showed that patient stress, patient in an agitated state, restraint application, patient movability, and individual intensive nursing were variables giving the greatest effect to UE probability. To verify agreement of the UE model with real situations, simulation with 5 cases was performed. Equation check and sensitivity analysis on TIME STEP were executed to validate model integrity. Conclusion: Results show that identification of a proper model enables prediction of UE probability. This prediction allows for adjustment of related factors, and provides basic data do develop nursing interventions to decrease UE.
