Purpose: This study aimed to identify the current status and correlations among scuba divers' knowledge of safety, compliance with safety rules, and ability to cope with emergency situations. Methods: There were 317 study subjects. Data were collected between September 21, 2012 and September 7, 2013, and analyzed using SPSS software version 21.0. Results: Of the participants, 89.3% wanted to be educated in emergency care, while 69.4% indicated that preparedness in emergency situations for divers is insufficient. 78.5% suggested a need to creat a legal standard for the prevention of accidents. The average scores among the participants showed 3.22 points for knowledge of safety, 3.09 points for compliance with safety rules, and 2.91 points for ability to cope with accidents and emergency situations, with strong correlation among them. The lower license level they had, the lower score they indicated. Conclusion: We suggest there is a need to strengthen systematic educations on knowledge of safety, compliance with safety rules, and the ability to cope with emergency situations and emergency care at the open water level. In addition, there is a need to creat legal standards to consolidate the effects of these changes.

The purpose of this study is to present basic data of clarifying the differences between employed and unemployed wives' family and comparing low classes with other classes for the more reasonable and successful home administration through investigating and analyzing decision-making patterns of the families of working women in the low income group. The questionnaires were distributed in September 1984 to 300 working women in the city of Seoul and Sung-Nam. Statistical methods such as frequency, percentage and the mean value were used for grasping general characteristics of the families and F-test, Pearson's Correlations were used for investigating the interrelation of the related variables. The results of this study were as follows; 1) Wife's participation indecision-making was increased while joint decision-making was decreased compared with those of unemployed wives' family and other classes. 2) Both of the degree of conjugal participation in decision-making and joint decision-making were influenced by wife's educational level, disparity in educations of couple, husbands' occupation, family income, wife's age. But duration of marriage affected only the degree of joint decision-making. Especially family income and husbands; occupations turned to be important variables in low income families. 3) In case of wife's satisfaction with her occupation, joint decision-making was well achieved or not according to certain decision items. Though wife and husband satisfied with their marriage, joint decision-making was not well performed in working wives' family with low income.

The objective of this study is to evaluate the education contents and method related to Korean culture by comparing history courses in interior design programs of korea to those of three ether countries. For this research, curricula and syllabus of forty interior design programs in domestic and foreign universities have been analysed. The major findings from the survey are summarized as follows: 1. In terms of the tradition contents ratio in history course United States ranks first, Japan second, China third, and Korea last. In case of Korea, the ratio of credits alloted to tradition to total credits is very low and most of the credits are elective courses not requirement ones. 2. History courses of Korean universities are biased to Western styles. 3. In terms of the ratio of contents about neighbor foreign countries'culture in history courses is United States first, Japan second, China third, and Korea last. Therefore it is proved that net only history courses are devaluated, but also the endeavor to find Korean identity is insufficient in the Korean interior design theory education.

For an analysis of dynamic behavior in carbon nanotube(CNT) which is widely used as micro and nano-sensors, an electrostatic force of CNT was investigated. For larger gaps in between sensor and electrode the van der Waals force can be ignored. The boundary condition in the CNT was assumed to clamped-clamped case at both ends. In this paper electrostatic force is expressed as linear equation along deflection using Taylor series. The first and second terms(${\zeta}_0$ and ${\zeta}_1$) of the linear equation are analyzed. Based on the simulation results nondimensional number ${\Phi}_0$ and ${\Phi}_1$ which came from ${\zeta}_0$ and ${\zeta}_1$ were decreased according to the increment of the gap. Reduction ratio of the second term ${\zeta}_1$ is increased up to 99% along to the increment of the gap. The higher order terms can be ignored and therefore, electrostatic force can be expressed using the first two terms of the linear equation. This results play an important role in analyzing the nonlinear dynamic behavior of the CNT as well as the pull-in voltage of simply supported switches.

The purpose of this study is to measure the level of the key competencies of industrial high school students and to use it as the basic material so as to improve the key competencies. The subject was 359 industrial high school students(boys: 244, girls: 115) in Seoul, Daejeon, Gwangju, and Busan. The instrument used to measure the key competencies is that developed by Cheol-Young Jeong, which was partly revised with the help of a group of experts. The results of this study showed some of skills were below an average of 3.0, which were writting skill(M=2.85) and speaking skill(M=2.96) in communication skills, logical thinking(M=2.98) in problem solving skills, leadership skill(M=2.88) in interpersonal skills, and self-improvement skill(M=2.96) and the spirit of public service(M=2.93) in self-management and self-improvement skills. But technology skills were above an average of 3.0. And it appeared that technology skills(P=.023) depended on having a certificate or not, and so did communication skills(P=.020) and problem solving skills(P=.034) on the types of a course(employment or entrance into a college). So, to strengthen the key competencies which appeared below an average of 3.0 in this study, not only does the curriculum of industrial high schools need to be reorganized, but systematic strengthening program of key competencies should also be developed.

This study analyzes the requests by the people-in-charge in industries and presents methods to improve field practice systems for technical highschools. Requests from 43 industries in Korea were analyzed. The results about improvement methods for field practices are as follows: First of all, the study suggests the same educational curriculums and number of courses for the 10th grade (National Manditory and Basic Curriculum) and the 11th grade (Elective Program) both in general technical highschools and in "2+1 system" technical highschools. The school offers a dual program: completion and continuation curriculums. In the 12th grade, students choose their careers. Students can participate in field practice as a completion education. In other words, the same curriculums are operated in 10th and 11th grades for students who want to go to college and to get jobs. The different curriculum is arranged for the 12th grade. This system can allow flexibility in curriculum operation for students who want to change their careers or who drop in the middle of filed practice. Students who come back to schools in the middle of field practice are asked to complete technical courses and evaluated like in general technical highschools.

In this paper, we have selected physical computing as the focused learning elements with the PBL-based programming instruction method. Students experienced physical computing by using Arduino. Development of robot using Arduino can create an effective educational environment and also provide solutions for lack of environmental conditions, such as time or spatial factor restrictions and excessive expense issues; these are major obstacles to developing robot programming education. Finally, we analyzed the effects on growth of student's logical thinking and problem solving abilities by demonstrating the Arduino application courseware to the field of education.

This paper is concerned with the study of 'Knowledge Management', a paradigm of thought based on the idea that the future will be a knowledge-centered society. This paper also provides an overview of both 'what to manage' and 'how to manage' if an organization wants to develop in this environment. The process of 'Knowledge Management' begins with a decision. Presented with a myriad of information, of which we can't afford to obtain it all, what information is of value to the organization? Further, by systematically organizing not only the primary information but also that which was accumulated in the process, Knowledge Management is capable of suggesting a value-added plan of action. This research presents the necessary principles needed in order to successfully use Knowledge Management, specifically a harmony between the human and technological aspects. There cannot be a static solution to the problem, as the environment of the enterprise's problem is dynamic in nature. Throughout the process, the enterprise will constantly change its strategy and structure in order to adapt to variable knowledge, technology, strategy, regulations, consumer interest, etc... The essential constant of these problems is the importance of spending on education. Investments in educations help develope a infrastructure for Information Technology, the development of knowledge distribution strategies, and the creation of efficient Knowledge Management policy.

Along with developments of information and communication technologies, internet has spread not only all over the society, but also our everyday life deeply. Also requirements for e-learning using internet in the educational aspect have a great influence on the changes of school educations. The benefits of e-learning are many, including cost-effectiveness, enhanced responsiveness to change, consistency, and timely contents. Therefore, the e-learning has been introduced to the universities. However, the e-learning is operated inefficiently because of introduction to the university with no definite idea about effects of education and economy in the university. Therefore, in this paper we analysed the category of e-learning based the curriculum operation forms in the university, surveyed tests about students preference and the studied what is desirable e-learning operation forms.
