This study was conducted to identify and analyze the educational needs for key vocational competency in nursing students. The participants were 411 nurse students at five universities and the survey was conducted from June 1 to June 31, 2016. The data were analyzed with SPSS WIN 23.0 using descriptive statistics, a paired T-test, Borich's Needs Analysis, as well as the Locus for Focus Model. Based on the results, the subjects recognized the present level of 'professional ethics,' 'self development' and 'interpersonal skills' to be high and those of 'communication skills' and 'skills for understanding groups' to be low. 'Professional ethics,' 'self development,' 'problem solving skills' and 'communication skills' were the most important sub-elements of vocational competency. A significant difference in recognition levels between present and importance ere found in all components of vocational competency. The four priorities were analyzed based on Borich's needs value. In accordance with the Locus for Focus model, 'communication skills,' 'problem solving,' 'resource management skills' and 'self development' were identified as the highest priority sub-factors of vocational competency to nursing students. Based on the result of this study, it is expected to be used as the basic data to develop the nursing student's vocational curriculum and program.

Recently, there was an increasing demand for an integrated access control system which is capable of user recognition, door control, and facility operations control for smart buildings automation. The market available door lock access control solutions need to be improved from the current level security of door locks operations where security is compromised when a password or digital keys are exposed to the strangers. At present, the access control system solution providers focusing on developing an automatic access control system using (RF) based technologies like bluetooth, WiFi, etc. All the existing automatic door access control technologies required an additional hardware interface and always vulnerable security threads. This paper proposes the user identification and authentication solution for automatic door lock control operations using camera based visible light communication (VLC) technology. This proposed approach use the cameras installed in building facility, user smart devices and IoT open source controller based LED light sensors installed in buildings infrastructure. The building facility installed IoT LED light sensors transmit the authorized user and facility information color grid code and the smart device camera decode the user informations and verify with stored user information then indicate the authentication status to the user and send authentication acknowledgement to facility door lock integrated camera to control the door lock operations. The camera based VLC receiver uses the artificial intelligence (AI) methods to decode VLC data to improve the VLC performance. This paper implements the testbed model using IoT open-source based LED light sensor with CCTV camera and user smartphone devices. The experiment results are verified with custom made convolutional neural network (CNN) based AI techniques for VLC deciding method on smart devices and PC based CCTV monitoring solutions. The archived experiment results confirm that proposed door access control solution is effective and robust for automatic door access control.

We have studied possibilities of Peer Instruction(PI) to train in-service science teachers in elementary and middle schools through both degree of conceptual changes and investigating responses to questionaries. 169 teachers were attended and the subject for training was about light propagation to teach scientific conception about a pin hole camera. 6 conceptests were developed. Degree of conceptual changes was analyzed from results obtained from 24 elementary and 32 middle school teachers among them. On the other hand, answers to questionaries were obtained from 135. Relatively high gain near to about 0.7 in conceptual changes was obtained even though their initial levels were quite low. Interesting point is that elementary teachers have higher initial level and larger gain than middle school teachers. Teachers have very much enjoyed and showed strong support to PI for helping conceptual change, and willing to use PI to their own class. Also they conceived dealing concept in teacher training is very important and evaluated PI very positively for teacher training.

An unmanned ground vehicle(UGV) today plays a significant role in both civilian and military areas. Predominantly these systems are used to replace humans in hazardous situations. To take unmanned ground vehicles systems to the next level and increase their capabilities and the range of missions they are able to perform in the combat field, new technologies are needed in the area of command and control. For this reason, we present war field simulator based on information fusion technology to efficiently control UGV. In this paper, we present the war field simulator which is made of critical components, that is, simulation controller, virtual image viewer, and remote control device to efficiently control UGV in the future combat fields. In our information fusion technology, improved methods of target detection, recognition, and location are proposed. In addition, time reduction method of target detection is also proposed. In the consequence of the operation test, we expect that our war field simulator based on information fusion technology plays an important role in the future military operation significantly.

The Cooperatives Act was enacted. This enabled people to establish easily cooperatives at various fields. A cooperative is an important vehicle for rural community development. Therefore, the enactment of the Cooperatives Act can be a significant chance for rural policy. The Cooperatives Act have made three significant changes. First, cooperatives can start businesses at all the fields except for financial and insurance business. Second, requisites for people to establish cooperatives have been alleviated exceptionaly. Third, the Cooperatives Act introduced a new cooperative organization, social cooperative which aims to serve the socially excluded class. The self-help approach places rural community members at the core of a development process with two goals: to improve the quality of life within the community and to facilitate the community's capacity building. Community cooperatives contribute to accomplish those goals. One of the roles for cooperatives is to provide products and services at competitive prices. Providing a good or service at a competitive price bcomes increasingly important in some rural communities declines. Cooperative development processes have bic impacts on the ablility of community members to increase human asset and social capital. We conducted a survey targeting rural community businesses to grasp inclinations toward establishing cooperatives. The Cooperatives Act has gained low level of recognition. But so many community businesses wanted to establish cooperatives. This means there is a possibility for many community businesses to establish cooperatives without sufficient understanding. We suggested some policy issues for coping with this situation, as followings. First, the governments should provides rural community residents with opportunities to learn about cooperatives. Second, the current legal systems and regulations about business and social service should be reviewed to do away with the possible discrimination between the new cooperatives and the other forms of incoporation. Third, the cooperation of cooperatives should be encouraged and facilitated in rural communities.

The usage status of trousers as school uniform for girl's middle and high school students in Seoul and the perception on trousers as school uniform were analyzed. Students who wore 'skirts only' were the greatest and students who wore 'trousers only' were higher in the case of winter uniform than in summer uniform. The most popular reason to wear skirts was 'because most of their fellow students wore skirts' in both winter and summer. The main reason for wearing trousers was 'because it was easy to cope with changes in temperature' in winter and 'because it allowed more comfortable movements' in summer. Students who wore trousers were generally satisfied with wearing trousers as school uniforms. However, they showed a low degree of satisfaction about design and color of trousers. The students preferred slim and straight trousers, and black col or with beige and blue being the next color. Students in general had low level of recognition for the need to wear trousers. Students perceived trousers as being cold-proof and comfortable for physical activities. But they also perceived that trousers were not suitable for improving their appearances and expressing their characteristics. Especially, the students who wore trousers tended to think that trousers reduced their cares for their personal attire and that trousers were good for wearing after school, but the students who did not wear trousers were found to think contrary.

In recent years, countries such as USA, United Kingdom and Australia have begun to implement national policies in order to systematically manage and share research data produced through publicly funded research. However, Korea as of yet does not have a coordinated research data policy. The lack of infrastructure that supports the sharing and preserving research data results in the poor management and loss of valuable data produced from significant national R&D investments. The need for research data collection, management and sharing goes beyond the outcome assessment of national research: it facilitates the diffusion of research impact and economic development. There is a growing recognition that data sharing is an essential element of research ethics. This research investigates the relevant research data policies and methods of governance at the national level using a case study analysis. United Kingdom was selected as a case study target as it shows a wide variety of policy examples and instruments. In particular, this research focuses on the UK's national legal framework for research data sharing, analyzes the RCUK (Research Councils UK)'s data policies, activities at the seven research councils under RCUK as well as several supporting institutions. Based on the analyses, this research offers a national roadmap for better managing and sharing of research data in Korea.

Human's landing strategies have been explained through lower extremity kinetics in various conditions. However, how lower extremity kinetics respond when the two conditions between a load and landing height are combined is not yet understood. To achieve the purpose of this study, a total of 20 men and women were subjected to drop landing according to a load(No load, 10%, 20%, 30% of the body weight) at various landing heights(0.3 m, 0.4 m, 0.5 m). As a result of the study, the main effect of a load was not statistically significant in all variables. But increasing of the landing heights showed more flexion angle which was statistically significant in knee joint. In addition, as the landing height increased, the medial-lateral, anterior-posterior, vertical force, and loading rate increased, while time to peak vertical force decreased which was statistically significant. Thus, humans can successfully perform the landing motion even if the load is changed at various heights. However, it reacted more sensitively to the change in landing height than that load condition. The landing height can be prepared for recognition and shock absorption through visual information, but the weight level is difficult for the body to perceive and explains why it is more difficult to apply it to the landing strategy mechanism for shock absorption.
As electronic mails are being widely used for facility and speedness of information communication, as the amount of spam mails which have malice and advertisement increase and cause lots of social and economic problem. A number of approaches have been proposed to alleviate the impact of spam. These approaches can be categorized into pre-acceptance and post-acceptance methods. Post-acceptance methods include bayesian filters, collaborative filtering and e-mail prioritization which are based on words or sentances. But, spammers are changing those characteristics and sending to avoid filtering system. In the case of Korean, the abnormal usages can be much more than other languages because syllable is composed of chosung, jungsung, and jongsung. Existing formal expressions and learning algorithms have the limits to meet with those changes promptly and efficiently. So, we present an methods for recognizing Korean abnormal language(Koral) to improve accuracy and efficiency of filtering system. The method is based on syllabic than word and Smith-waterman algorithm. Through the experiment on filter keyword and e-mail extracted from mail server, we confirmed that Koral is recognized exactly according to similarity level. The required time and space costs are within the permitted limit.

Construction Management(CM) and Building Information Management(BIM) have a lot in common that they need to establish a cooperation system among different disciplines and promote smooth communication among project stakeholders throughout the project life-cycle. BIM can be an effective information management tool for CM's business and improve their service value. However, BIM uses by Construction Managers(CMr) are very limited. The objective of this study is to analyze the intention of CMrs to adopt BIM and establish effective BIM use strategy in the CMr's point of view. This study utilizes Technology Acceptance Model(TAM) as a research method, and the results show that 1) CMrs think it is more important whether BIM is required to be adopted in their business process at the social or industry level than that BIM can improve their personal competence, recognition, and impressions through their voluntary BIM adoption; 2) that CMrs think it is important to figure out business processes where BIM can be smoothly incorporated; and 3) that CMrs hesitate the use and trial of BIM in their realworld business although they agree that BIM needs to be eventually adopted in their business in the future. Based on these results, directions for establish a strategy for BIM adoption were proposed at the CMr's point of view
