This study determined the correlation between College Life in Freshmen critical thinking disposition; problem solving process. It also examined the impact of critical thinking disposition on problem solving process. The data was collected from 215 Freshmen members. Descriptive statistics, t-test, ANOVA, scheffe test, pearson correlation analysis and multiple regression analysis were performed. Results: In critical thinking disposition, there were significants differences in age, interpersonal relationships. In multiple regression analysis, critical thinking disposition and major satisfaction were significants factors of problem process ability explaining 38% Conclusion: To enhance problem process ability for freshmen, it is necessary to develop teaching program and curriculum.

Official Development Assistance(ODA) Project is initiated to assist a developing country economically and to promote its welfare. Support on training and information system development are the primary elements in the maritime safety field. The maritime safety information system(MSIS) of ODA projects deals with maritime safety information of developing nations and ensures an inter-operability between other systems. Therefore, it is required to develop MSIS based on the Universal Hydrographic Data Model(UHDM) of International Hydrographic Organization(IHO). In this paper, we have analyzed the current status and operational process of UHDM established by IHO. Oil spill response system was selected as an example of MSIS project and, also, considered the application results to the maritime safety field of UHDM.

The purpose of this study was to analyze the conception type change and to investigate the effect of understanding on concepts in electrochemistry after general chemistry lessons. The significant differences in concept understanding of electrochemistry were shown in both groups. Statistically significant gains in both groups were as shown in distinguishing the chemical cell, in identifying the anode and cathode, and in understanding current formation and flow, while, significant achievements in understanding the role of the salt bridge, and the need for a standard half-cell were not found. Taking elective chemistry II in high school had an effect on understanding related concepts of electrochemistry in general chemistry lessons. It was shown that many freshmen had difficulties in understanding exact related concepts in several kinds after general chemistry lessons. In order to solve these problems, it is necessary to teach contents of the basic concepts in electrochemistry exactly and to hold supplementary lessons.

The purpose of this study was to identify the factors affecting the motivation for blood donation participation of university students. The subjects of this study were 200 university students in one area, and a self-report questionnaire was used for data collection. The data analysis used frequency, percentage, mean, standard deviation, Independent T-test, One-way ANOVA, Pearson Correlation Coefficient, and Multiple Regression Analysis. As a result of the study, the factors influencing the subjects' motivation to participate in blood donation were significant in the order of attitude toward blood donation, future blood donation plan, perceived health status, altruism, and number of blood donation experiences. The results of this study can be used as basic data for the development of educational programs to increase the motivation for blood donation participation of university students. It also suggests that there is a need to develop strategies that can increase university students' attitudes toward blood donation, altruism, and health status.

The government and public institutions are conducting public-opinion surveys as means of drawing the scientific policy decisions throughout the country's whole sectors ; society, culture, welfare, education, etc. The Government Survey Data have been under management by each governmental department, but the improper ways of data collection and management have led to omissions and losses of some data. Also there are limitations on the statistic usage and access to the data due to the fact that the data are managed dispersedly in the form of printed materials. Accordingly, to make the survey data available for the long-term preservation and usage, this study suggests collection policy, standard of evaluation, metadata, the procedure and method of converting materials, preservation format.

The importance of the security management system for the aviation infrastructure cannot be overemphasized. What is especially important on the security management system for it is the assessment that is detaild and systematic. This article presents a framework based on a Hanulcha-type security management system model for a Information security of the Aviation infrastructure. This system checks, estimates and analyzes the goal of security with effect, especially in case of the security-accident on the aviation infrastructure because this system model gives the integrated security assessment method.

This paper presents an improved evaluation method, based on National Competency Standards (NCS), of National Technical Qualification (NTQ) examination in Electronics Fields such as Craftsman Computer, Industrial Engineer Computer Maintenance Control, Engineer Computer System Application, Engineer Computer, Engineer Embedded) to reflect practical vocational abilities and raise values of NTQ certificates. To evaluate each NTQ examination, we carefully chose corresponding NCS competency units for practical performance test, written subjective test, and mixed test through the advisory committee with industry, education, and qualification experts. In addition, we verified useful effects of the NCS-based evaluation method by performing and analyzing the simulated tests. We used both single and mixed problems in practical performance test and new problems about system design and implementation based on various working scenarios in written subjective test.

In this study, a new dynamic VRF-type heat pump simulation model is proposed which incorporates frosting and defrosting models. Toward this end, a simple frosting model based on the perfect analogy, and lumped system based defrost model, are proposed. Then, frosting and defrosting models are incorporated into a dynamic heat pump model which adopts segment-by-segment local heat exchanger model and map-based variable speed compressor model. Thus, the model can naturally represent locally uneven frosting and defrosting on the heat exchanger surface. Developed simulation model is validated against available experimental data to show good agreement within 10% error for capacity and COP. Finally, developed dynamic heat pump model is applied to annual heating season simulation to show that seasonal COP of heat pump is degraded by 7% due to frosting and defrosting.

This study examined the influence of meta-cognition, self-efficiency and clinical competence in nursing students. A convenience sample of 153 subjects were recruited from fourth year nursing students, and the survey was conducted from September 1st to 30th 2015. The data were collected by questionnaires and analyzed SPSS/Win 18.0 program, using descriptive statistics, Pearson's correlation coefficient, t-test, one-way ANOVA and hierarchical regression. Significant positive correlation among the meta-cognition, self-efficiency and clinical competence were found. The regression model explained 27% of the clinical competence. The meta-cognition and self-efficiency for the nursing students were factors influencing clinical competence. Therefor, it is necessary develop an educational program to improve the meta-cognition and self-efficiency of nursing students.

For Knowledge Information Governance, integration search mechanism of Knowledge Information is required in various industries. But when Knowledge Information system constructs in each professional field, it developed and used its own metadata format. Accordingly, if distributed information system searches using metadata, heterogeneous problems are occurred among metadata. For integration search, it needs a consistency management of metadata. Therefore, this paper defines a standard metadata that represent standard metadata as surveying a used metadata in each field systems. Also, we propose a metadata registry integration framework for Knowledge Information Governance. It enables an integration search service without a metadata modification of existing system. Through the proposed framework, it can registries and manages efficiently the existing metadata. Also, it enables a semantically extended search using semantic relation between metadata.
