  • The purpose of this study was to investigate the MBTI personality type, emotional intelligence, and stress coping strategies of nursing students and to examine the influence of these factors on their level of college adjustment.The subjects were 267 nursing students who are located in Chonnam city. The survey was conducted from March 6th to March 31st, 2017. The level of college adjustment showed a close correlation with the emotional intelligence(r=.29, p<.001) and stress coping strategies(r=.27, p<.001), and the level of MBTI personality type was not statistically insignificant in the nursing students. It was found that the effect of the emotional intelligence and stress coping strategies on the college life adjustment was 17.5%(F=8.03, p<.001). According to the results of this study, it is necessary to develop a systematic management program to integrate the educational curriculum and extra-curricular activities(in order to enhance the) emotional intelligence and stress coping strategies in nursing students. In addition, the type of psychological function and psychological temperament of the MBTI personality type were found not to have influenced the level of college adaptation of the nursing students and this should be confirmedin a large scale sample.

  • The policy-making and technological development of eco-friendly automobiles designed to increase their supply is ongoing, but the internal combustion engine still accounts for about 95% of the automobiles in use. Also, in order to meet the stricter emission regulations of internal combustion engines based on fossil fuels, the proportion of after-treatments for vehicles and (ocean going) vessels is gradually increasing. Natural gas is a clean fuel that emits few air pollutants and has been used mainly as a fuel for city buses. In the long term, we intend to develop a new NGOC/LNT+NGCO/SCR combined system that simultaneously reduces the toxic gases, $CH_4$ and NOx, emitted from CNG buses. The objective of this study is to investigate the characteristics of $de-CH_4/NOx$ according to the ceramic and metal substrates of the SCR (Selective Catalytic Reduction) catalysts mounted downstream of the combined system. The V and Cu-SCR catalysts did not affect the $CH_4$ oxidation reaction, the two NGOC/SCR catalysts each coated with two layers began to oxidize $CH_4$ at $400^{\circ}C$, and the amount of $CH_4$ emitted was reduced to about 20% of its initial value at about $550^{\circ}C$. The two NGOC/SCR catalysts each coated with two layers showed a negative (-) NOx conversion rate above $350^{\circ}C$. The ceramic-based combined system reached LOT50 at $500^{\circ}C$, which was about 20% higher in terms of the $CH_4$ conversion rate than the metal-based combined system, showing that the combined system of NGOC/LNT+Cu-SCR is a suitable combination.

  • This study was conducted to investigate the elementary school students' consciousness of safety, activities to prevent their accidents and factors causing such accidents. For this aim, a research was conducted from Nov. 19 through Dec. 22, 2007 by means of questionnaires distributed to 800 students enrolled in the 5th and 6th grades of 4 elementary schools in a urban-rural combined city. Out of the questionnaires distributed, 785 were collected and put to analysis by using SPSS 13.0 program to determine t-test, ANOVA, logistic regression, etc. 1. The maximum scores of safety consciousness revealing relatively high level of safety consciousness. There was, however, statistically significant difference by grade, type of residence, school life and academic achievements. In detail, 5th graders featured higher level of safety consciousness and those who live in apartments, lead a pleasant life at school and get better academic scores tended to keep higher level of safety consciousness. 2. The subjects of the high scored of activities to prevent accidents, with a statistically significant difference by gender, grade and individual personality. Females, 5th graders and active students were found to be more conscious of preventive activities for accidents. 3. In general, 6th graders and active students turned out to have experienced more accidents. 4. The main factors exerting influence on occurrence of accidents on the part of elementary school students are known to be preventive actions and consciousness of traffic safety in the category of safety consciousness. The significant variable in preventive actions was preventive actions of traffic accidents, burns and intoxication by category of accidents, but individual personality by category of general characters. Sixth graders and male students experienced more accidents, without significantly significant difference, though. As a result, From the above findings, prevention of safety accidents is found to be very important for elementary school students. It is therefore suggested that schools as well as homes should continue to conduct practical education to prevent accidents with priority placed on familiarizing students with preventive activities in daily life in consideration of their personal characters.

  • This study was carried out to grasp the job stress and intention to change their jobs of nurses at general hospitals by their socio-demographic, job-related and health-related behavior characteristics and especially to investigate their relationship to the job stress and intention to change their jobs. The subjects were 355 nurses working at three university hospitals located in Daejeon City, and data were collected by a survey using self-administered questionnaires structured from April 1 to May 31, 2012. As a results, the average point of the nurses' intention to change jobs by the causes for job stress was significantly higher in the boss group with low support than in that with high support while it was higher in colleague group with low support than in that with high support. To look into the correlation between the points of intention to change their jobs and the causes for job stress, their intention to change their jobs showed a significant negative correlation to the boss's support and colleagues' support while there was no significant relationship with job demands and job autonomy. As a result of hierarchical multiple regression, age, drinking coffee, department, job satisfaction, the boss's support and colleagues' support were selected as significant related variables affecting the nurses' intention to change their jobs and these variables' descriptive power was 29.4%. Viewed from the above results, it is suggested that the nurses' job stress and intention to change their jobs has a significant relationship with various variables such as socio-demographic, health-related behavior and job-related characteristics. In addition, there were a significant positive correlation between the causes for the job stress cause and intention to change their jobs, and among the causes for the job stress, support by their boss or colleagues turned out to be those affecting their intention to change their jobs. Thus, it is considered that it is necessary to minimize the nurses' job stress and at the same time to seek for specific measures for preventing their turnover.

  • As fossil fuels are depleted worldwide, alternative resources is required to replace fossil fuels, and biofuels are in the spotlight as alternative resources. Biofuels are produced from biomass, which is a renewable resource to produce biofuels or bio-chemicals. Especially, in order to substitute fossil fuels, the research focusing the biofuel (biodiesel) production based on CO2 and biomass achieves more attention recently. To produce biomass-based biodiesel, the development of a supply chain network is required considering the amounts of feedstocks (ex, CO2 and water) required producing biodiesel, potential locations and capacities of bio-refineries, and transportations of biodiesel produced at biorefineries to demand cities. Although many studies of the biomass-based biodiesel supply chain network are performed, there are few types of research handled the uncertainty in CO2 supply which influences the optimal strategies of microalgae-based biodiesel production. Because CO2, which is used in the production of microalgae-based biodiesel as one of important resources, is captured from the off-gases emitted in power plants, the uncertainty in CO2 supply from power plants has big impacts on the optimal configuration of the biodiesel supply chain network. Therefore, in this study, to handle those issues, we develop the two-stage stochastic model to determine the optimal strategies of the biodiesel supply chain network considering the uncertainty in CO2 supply. The goal of the proposed model is to minimize the expected total cost of the biodiesel supply chain network considering the uncertain CO2 supply as well as satisfy diesel demands at each city. This model conducted a case study satisfying 10% diesel demand in the Republic of Korea. The overall cost of the stochastic model (US$ 12.9/gallon·y) is slightly higher (23%) than that of the deterministic model (US$ 10.5/gallon·y). Fluctuations in CO2 supply (stochastic model) had a significant impact on the optimal strategies of the biodiesel supply network.

  • The purpose of this study was to investigate the effects of case-based learning about infants and toddlers on healthcare department students, using a video in an emergency care environment. A total of 57 students from a healthcare department of D university in J city were enrolled. They were divided into two groups: The experimental group (n=29) and the control group (n=28). This study is pre-post designed with a non-equivalent control group. The experimental group received a 1-week education for a duration of 3 weeks (3 sessions in total) with 180 minutes per session. The control group received a traditional curriculum of lecture. Before and after the education, we measured the knowledge and skill confidence of emergency care toward infants and toddlers, the academic self-efficacy, and problem solving ability. Data collection and intervention were carried out from November to December of 2014. Data were analyzed with x2-test, paired t-test, unpaired t-test with SPSS version 20.0 Program. The experimental group showed a significantly higher improvement of skill confidence of emergency care toward infants and toddlers (P<001), as well as preferred task difficulty among sub-items of academic self-efficacy (p=.029), approach avoidance style (P=.001), and problem solving confidence (p=.040) among sub-items of problem solving ability on preference compared with the control group. In this study, a case-based learning was verified to be an effective teaching method to enhance professional competency of healthcare department students. The findings from this study suggest that a case-based learning using various educational contents should be developed, expanded, and carried out to promote better learning.
