Korea Ocean Research and Development Institute performed the basic design of the Ear-Do Ocean Research Station in 1998. The design wave was taken to be the deep water wave which was obtained through wave hindcasting procedure. Wave forces acting on the structure were calculated by Morison formula utilizing the stream function theory of 5th. order. In the present study, a three dimensional hydraulic model testing was undertaken to investigate the validity of the basic design, measuring wave propagation over the Ear-Do, horizontal wave forces and air gaps. The measured forces were all compared by the corresponding values calculated by SACS program based on th design on the design wave. The results showed that in the three deep water wave directions (SSW, S, SE) the measured wave farces appeared less than the SACS calculated. But in the NNW wave direction, the measured forces generally exceeded the calculated values and showed a peculiar pattern very similar to the case that waves are superimposed by an unidirectional current. It was also found that the measured air gap underneath the structure appeared less than the values taken in the basic design for all wave directions.

This study explores the way to enhance research performance focusing basic and fundamental technology when researchers conduct international joint research with counterparts in foreign countries, funded under the National R&D programs. In order to retain validity and objectivity, mixed approaches including qualitative and quantitative are adapted at the first step. Through this step, main factors affecting the research performance can be addressed, such as the number of SCI papers published, conference attendance held both in domestic and foreign countries, researchers holding PhD involving in projects. Then, at the second step, DEA methodology is applied to explore the way to enhance research performance, based on the analysis at first step. The result at second step shows that the various ways can be drawn according to programs respectively and the general assumption of research funds and number of projects affecting positive outcome is not absolutely mentioned. Therefore, this study implies that input variables including research funds are not compatible with research performance in terms of international joint research and suggests further that the decisive outcome and management be reconsidered according to the programs respectively under the national R&D program.

In Korea, there is a high demand for the operation of differentiated programs in basic research considering the characteristics of academic fields. The results of this study shows that the higher the level of research competence, the higher the quality of research outputs. The results also tell us that the quality level of the research outputs is different according to the field of study. Based on the results, we propose a method to differentiate the selection rate of each discipline in the system that operates the individual basic research projects by the level of research capacity.

Basic design of a solar driven absorption cooling machine(SDACM) with a cooling capacity of 5 USRT was carried out. The SDACM is a single effect cycle driven by low temperature hot water from solar collectors. The SDACM design data were calculated by the steady state simulation program which was developed in this study The variation of COP and cooling capacity of the SDACM were investigated at different off-design conditions. Both the cooling capacity and the system COP were improved with decreasing cooling water temperature. If hot water temperature was increased, the cooling capacity was improved but the system COP was found to be decreased. The decrease of the system COP were basically caused by increased thermal loads in the system components.

This study was carried out to develop a physics education program for foreign students of university in Korea to improve their ability to major in the field and to prevent them from becoming dropout. The subjects of the study are five Chinese students attending a natural science and engineering college. Prior to the development of the physics education program, the researchers developed basic physics textbooks for the foreign students and questionaries for diagnosis and summative evaluation, and utilized them to apply a total of seven classes. After the application of the classes, the results of the student's diagnosis and summative evaluation, the teacher's diaries, the observer's diaries, and the transcripts were analyzed by triangulation method. In addition, Nvivo12 was used for the analysis of the teacher's and observer's diaries to help with qualitative analysis. The results of the study are as follows: First, the oder and contents of physics education program for students of the natural science and engineering college were presented in detail, and basic physics textbooks and tools for diagnosis and summative assessment were developed. Second, as a result of the analysis of the diagnosis and summative assessment results of the program, the students' basic physics achievement improved by an average of 40 points due to the application of the developed program. Third, as a result of the application of the program using Nvivo12, meaningful node and actual cases were extracted. There were 10 types of nodes created such as understanding of the students, teaching method, rate of the participation, level differences, language problems, relevance to majors, curriculum and methods of education in the country of origin, cooperative learning, and interest inducement. The researcher provided suggestions on physics education methods for students of science and engineering colleges in Korea based on the related cases.

As essential element of designers, foundation studies program helps student deal with the individual expression of imagination and variety of correspondence for solving design problem through the understanding of 2-D, 3-D basic design elements, principals, structures. Liberal art and foundation studio courses provides embodiment and settlement of design principal through the foundation studies expand to experiences systematically and deeply. After the Industrialization, foundation studies have developed from Bauhaus in German, the courses have been progressing and systematizing with the demand of time in United States. Growth of Industrialization, expanded design areas departmentalized to various of fields, then the segmentation of foundation courses tend to important than basic design courses. The introduction of information era, the appearance of computer is placed as a tool of design development and added to applied basic courses. This study is intended to know how to change the leading foundation courses in United State due to the revitalization of industrialization and information through the research and analyse to foundation design education curriculums. As a result, most of design school in United States provide drawing, 2-D, 3-D, and 4-D courses included 3-D design element as a basic studies and provide to students introduction to fundamental principal of design concept and communication in both theoretical and applied form. Also though the history, literature, critic, research and survey courses provide students to organize fundamental of systematical logic and understanding design system.

Purpose: This descriptive study examined awareness of and ethical attitudes associated with Do Not Resuscitate (DNR) orders in 119 emergency medical technicians (EMTs). Method: In total, 255 paramedics and basic EMTs completed questionnaires between March and May, 2013. Data were analyzed using the SPSS WIN 18.0 program. Results: A chi-square analysis revealed significantly different responses given by paramedics and basic EMTs: Paramedics gave "the reason in which DNR is not necessary", as being "due to unclear DNR decision time" whereas basic EMTs answered that this was "due to a legal problem" ($x^2$ = 12.680, p < .05). Paramedics disagreed with the statement, "It is natural for medical teams to have less interest in patients with DNT orders", whereas basic EMTs agreed with the statement ($x^2$ = 6.666, p < .05). Conclusion: A unified manual on attitude toward DNR orders, taking account of social and culture factors, needs to be developed. This research provides a base line for future research.
