In this study, microorganisms were isolated from nosocomial environment and are identified by biochemical analysis as the part of biochemical and technical convergence. Microorganisms were collected at intense care unit of general hospital located in Pyeongtak (2014.11.28. - 2014. 11. 30). Using a VITEK2 equipment of biochemical approaches, eleven microorganisms e.g., Micrococcus luteus (or M. lylae), Granulicatella adiacens (M. luteus or M. lylae), Staphylococcus caprae, Sphingomonas paucimobilis, Kocuria kristinae, G elegans, Aerococcus viridans (or Staphylococcus arlettae), Methylobacterium spp., Dermacoccus nishinomiyaensis (or Kytococcus sedentarius), Kocuria kristinae (or M. luteus, M. lylae), Pseudomonas oryzihabitans were identified. And then identified bacteria plates were applied with a plastic stick, so called with "FarmeTok (medistick/Puristic) to produce ClO2. ClO2-releasing plastic stick showed the very strong inhibition of bacterial growth with about 99.9%. There were no bacterial colonies on the ClO2-incubated plate. Taken together, it is suggested that chlorine dioxide should be very strong inhibitor to microorganisms of nosocomial infections.

The purpose of this study is to investigate the convergence effects of the experience of adult preventive care on the treatment satisfaction and the dental fear, and the survey was conducted from January to April 2017 for 292 adults of aged 20 years or older living in the metropolitan area. The collected data were subjected to $x^2-test$, t-test and multiple regression analysis using SPSS 22.0 program. Fluoride application was the most prevalent experience of adult preventive treatment, and the satisfaction level of the treatment was high in case of fluoride application was experienced. On the other hand, dental fear was lower if preventive scaling was experienced. As a result of multiple regression analysis, variables affecting patient satisfaction were experience of fluoride application, and the variables affecting dental fear level were oral health condition and preventive scaling experience. The result of this study was confirmed that the satisfaction level of treatment was increased and the dental fear was lowered. Therefore, improvement of oral health promotion can be expected by recognizing of the importance of preventive treatment and providing of the dental preventive service through oral health education.

This study aimed to understand experiences of compassion fatigue reported by nurses providing services to oncology patients and families. We conducted in-depth interviews with 8 nurses currently working in oncology. Three main themes and 13 subthemes were extracted from the thematic analysis suggested by Braun and Clarke. Participants experienced compassion fatigue while feeling the sufferings transferred from patients and caregivers. The stress resulted from unique nature of oncology work added to their compassion fatigue. Participants became running low on empathy towards oncology patients and caregivers because of external work environments and negative perceptions on compassion. The results of the study inform health care professionals about increasing awareness of compassion fatigue of nurses working with oncology patients and families and the importance of providing interventions to promote their individual and professional quality of life.

With regard to urban culture this study aims to essential understanding and systematic approach to the culture. The "2012 Seoul Survey" report has been used to find out causality among the related variables. In the first place 'satisfaction of cultural condition' was operationally selected as a dependent variable for regression. For the purpose of controlling the third factors for ceteris paribus effect correlation analysis was previously done between the dependent variable and all other variables respectively, which resulted in two groups of variables: group (1) - 2 variables of very significant correlations(p-value<0.01) and (2) - the other 6 variables of significant correlations(p-value<0.05). Then hierarchical regression was adopted to these 2 groups to analyse statistical significance of independent variables, and multicollinearity(VIF; variance inflation factor). Additionally to OLS robust and bootstrapping regressions were done to confirm the validity of this model specification. At last a regression model specified by group (1) as independent variables(they are 'community spirit caring for women, the disabled, the poor and the old,' 'satisfaction of bicycle riding condition' shows that the variables have statistically significant and substantially strong effect on 'satisfaction of cultural condition.' This finding implies the following understanding; (1) urban festivals are regarded as the main of the urban culture as of now and this results from the low level of today's culture, (2) culture is telling and hearing stories but the influential relationship between urban culture and community spirit on the weak is negative, which says that the cultural perception among citizen is somewhat selfish and far from the essential understanding of the urban culture. In spite of restrictive external validity this finding can be used as a direction for promoting culture and a basis for related policy choice in cities.

Pair programming is a software development technique in which two programmers work together at one computer. One writes code while the other reviews the code, and they switch roles frequently. Pair-programming practice in school programming lab is expected to improve the learning performance, provide collaboration experience, and promote interactions between students. This work finds out how students accept pair-programming, what make students reluctant to join pair-programming by repeated questionnaire surveys in a college programming lab class. Based on these findings aome guidelines for school pair-programming are provided. First, students should be allowed to choose to do pair-programming or not. Second, various obstacles that make students hesitate to switch roles should be removed. Third, the pair matching should be made with great care.

Currently, the electric fire prediction system uses PIC(Peripheral Interface Controller) for controller microprocessor. PIC has a slower computing speed than DSP does, so its real-time computing ability is inadequate. So with the basic characteristics waveform during arc generation as the standard reference, the comparison to this reference is used to predict and alarm electric fire from arc. While such alarm can be detected and taken care of from a remote central server, that prediction error rate is high and remote control in mobile environment is not available. In this article, the arc detection of time domain and frequency domain and wavelet-based adaptation algorithm executing the adaptation algorithm in conversion domain were applied to develop an electric fire prediction system loaded with new real-time arc detection algorithm using DSP. Also, remote control was made available through iPhone environment-based app development which enabled remote monitoring for arc's electric signal and power quality, and its utility was verified.
