Purpose: The purpose of this study was to offer the baseline data for developing a systematic and high quality of clinical practice guideline by exploring how nurses utilize clinical guidelines and what they need for. Method: This study has been done with 242 nurses of a university hospital in Daegu using a self-administered questionnaire. The instrument used in this study was developed by researchers based on the results of the previous studies. Data analysis was done with SPSS 11.0 Program. Results: Nurses felt that clinical guidelines were not sufficiently disseminated to update their clinical knowledge education. Nurses showed the strong demand for developing clinical practice guidelines with the newest and systematic evidence. However, a relatively low number of nurses knew evidence-based nursing and evidence-based clinical guidelines. Conclusion: It is necessary to develop an educational program for evidence-based nursing and an evidence-based nursing clinical practice guideline for nurses and to explore the strategies for development and dissemination of evidence-based clinical practice guidelines to solve the urgent and frequent clinical problems.

At the United Nations High-level Meeting on Non-communicable Disease Prevention and Control in 2011 the link between health and socioeconomic issues was raised, becoming a global political issue. Health equity is one challenge that has hitherto not been addressed directly, although there is a growing shared recognition that cancer in Asia is an urgent social issue. At the UICC-ARO we are working to promote and widen networks of individuals and organizations in Asia and involve them in cooperation for this purpose. As part of our current activities, we are addressing the question of the "Economic burden of cancer in Asian countries: How should we face the current situation?" from a variety of angles and seeking to bring together a wealth of multidisciplinary knowledge about cancer in Asia and its related socioeconomic factors. It is essential to ensure that the real picture of cancer in Asia, which is currently not accurately understood, is conveyed clearly to all concerned, and also that the differences between cancer in Asia and in the West are highlighted.

In our daily life, the need of energy increases day by day. However, the amount of natural resources on the earth is limited and thus gaining renewable energy as an energy resource is one of the important and urgent problems. Solar energy is one of the most popular available energy sources that can be converted into electricity by using solar panels. In order for solar panels to produce maximal output power, the incident angle of the sunlight needs to be persistently perpendicular to the solar panel. By the way, most of the solar panels are installed at fixed position and direction. Therefore, as the sun's position changes, it is impossible to produce maximal output power inevitably. To improve this problem, in this paper, a sun tracking system using two degree-of-freedom (DOF) active sensor array is proposed so that the solar panel may always direct sunlight perpendicularly. And also a series of software, such as a search mode and a holding mode, which can control the developed sun tracking system is developed. Several experiments using the implemented sun tracking system are executed and the effectiveness of the system is verified from the experimental results.

Removal of spilled oil over the sea and the river has become one of the urgent problems in these days. Removing oil using mechanical devices was recommended because chemical dispersion could cause the secondary contamination in the environment. In the present study a series of experiments were carried out to study the effect of operating conditions, especially, the angle between the belt and the fluid surface on the rate of recovery for the spilled oil using a belt skimmer. Three different types of operation, namely, upward pickup, downward pickup and up-and-downward pickup situations have been investigated for various contact angles, belt speeds and oil thicknesses to find the effects on the recovery rate. The highest rate of oil recovery was found in the case of a contact angle of $45^{\circ}$ and downward pickup. Furthermore, an optimal belt speed was found to reach the saturated recovery rate for a given oil thickness.

In order to apply SFCLs into electric power systems, the urgent issues to be settled are as follows, such as initial installation price, operation and maintenance cost due to ac loss of superconductor and the life of cryostat, and high voltage and high current problems. We designed novel hybrid SFCLs which combine superconductor and conventional electric equipments including a vacuum interrupter, an electro-magnetic contactor and a current limiting reactor. The main purpose of the hybrid SFCL is to drastically reduce total usage of superconductor by adopting current commutation method by use of the superconductor and the fast switch. According to protective coordination and performance, we investigated two concepts of Hybrid SFCLs. First is a half cycle fault current limitation type and second is a non-half cycle fault current limitation type. We concluded that the non-half cycle fault current limitation type is batter than the other.

This thesis mainly studies the Commercial Mediation System in China and its Implications to Korea. Commercial mediation is an important dispute settlement method, however there are more studies on the issues of arbitration than the ones on mediation. Commercial mediation emerges From the tide of economic activity, needing an earnest research and to be developed. Business mediation law has been enacted in some nations like USA, but in Korea, there is no law in mediation field to follow. To set up business mediation law is necessary and urgent as well as feasible. This thesis first introduces the mediation of the general meaning including concept, makes a research concerning the sorts of the mediation, compares the effect of different kinds of mediation, and studies the current status of use of mediation in other countries. Than introduces current status of use of mediation in China, and examine mediation system in China. Through this studies, the writer no that there is almost equal problem in China comparing to Korea. So than examine how Chinese government make countermeasures to cover their problems, and give Korean government several implications that can learn from China.

It is urgent to prepare countermeasures for traffic congestion problems of Korea's metropolitan area where central functions such as economic, social, cultural, and education are excessively concentrated. Most users of public transportation in metropolitan areas including Seoul use the traffic cards. If various information is extracted from traffic big data produced by the traffic cards, they can provide basic data for transport policies, land usages, or facility plans. Therefore, in this study, we extract valuable information such as the subway passengers' frequent travel patterns from the big traffic data provided by the Seoul Metropolitan Government Big Data Campus. For this, we use a Hadoop (High-Availability Distributed Object-Oriented Platform) to preprocess the big data and store it into a Mongo database in order to analyze it by a sequential pattern data mining technique. Since we analysis the actual big data, that is, the traffic cards' data provided by the Seoul Metropolitan Government Big Data Campus, the analyzed results can be used as an important referenced data when the Seoul government makes a plan about the metropolitan traffic policies.

This paper suggests smart agricultural diffusion strategy through advanced ICT technology. Today, the world is threatened by environmental pollution and traditional warming due to global warming, and the decrease in agricultural workers due to low fertility and aging is expected to bring social problems to future food resources. The convergence of ICT technology and agriculture is not a labor-intensive primary industry, but a new paradigm that includes cultivation, manufacturing and services. It is urgent to spread smart farm technology that can supply stable food with low labor force. In this paper, we review the current state of smart farm technology, analyze the impediments to diffusion, and present the direction of smart agricultural development in the future by upgrading ICT technology.

Purpose: The aim of this study is to provide baseline data on the housing environment of a vulnerable population. Methods: This study provides a descriptive survey on the housing environment of a vulnerable population of a city in Gyeong-gi province. A total of 9,061 households were selected as research participants. Data were collected through face-to-face interviews by visiting nurses from February 2014 to March 2014. Results: Interviewees answered "poor" on items including cold drafts, illumination, daylight penetration, inflow of polluted air, house odor, stairs safety, noise, mold, pests, and ventilation. The score for housing environment problems showed a significant group difference due to gender, age, economic status, family type, type of housing, and type of ownership. Conclusion: These results indicate that the vulnerable population is exposed to a poor housing environment. Thus, there is an urgent need to improve the housing environment for the vulnerable population. Based on this study, linking a visiting health care service program and housing environment improvement projects from relevant administrative agencies might be recommended in order to effectively improve the housing environment.
