Sinkholes happen in increasingly higher frequency in downtown areas with a concentration of social infrastructure these days. Most sinkholes occur around the living areas of citizens, which calls for a systematic countermeasure plan for urban development and underground water management, which are parts of the main causes of sinkholes. This study thus set out to analyze the risk factors of sinkholes in the subject area by using geospatial information deeply connected to sinkholes both directly and indirectly. The geospatial information used in analysis was obtained by examining the causes of sinkholes from a topographical perspective. Collected data were treated and analyzed with a range of spatial analysis tools based on GIS. The findings show that topographical factors had significant relations with sinkhole causes and raise a need to manage all kinds of pipe networks underground, the movement characteristics of underground water levels, and other topographical features. The findings may serve as data to support decision-making processes in the field of urban disaster prevention and call for extensive research to incorporate hydro-geomorphology and spatial modeling.

A sense of oneness between a player and an avatar is more emphasized than role-playing itself in Korean RPG playing. Because of this tendency, the main contents of smart phone-based mobile RPG are mainly focus on combat. As PvP occurs more frequently in mobile RPG, playing experiences are diversified from sensitive control to simple repetition. Also, the auto-combat function offered in game system ingenerates funs from testing a mental model that a player statistically sets before playing. This paper analyzes the process of generating fun in mobile RPG based on Ralph Koster's Game Grammar theory. is selected as subject of this analysis. The pattern of mobile RPG playing is dichotomized : automation of producing materials and concentration on raid and PvP contents.

As the electricity produced from the electricity industry, a national key industry in Korea, are supplied to other industries as an intermediate goods, the supply shortage of electricity industry has a large impact on the national economy. This paper attempts to analyze the supply shortage effects which are defined as the negative impact of one won of supply failure in the electricity on the production of other industries. To this end, an input-output analysis using an input-output (I-O) table describing inter-industry flow of intermediate goods is applied. More concretely, the supply-driven model is applied subject to the OECD countries. The value of the supply effects interfere with Denmark's best large 1.682 was followed by South Korea, Japan, Australia, the UK.

In this study, the amalgamative relationship associated with oral health belief and preventive behavior against oral disease subject to middle aged people was analyzed. 20 persons in their middle age living in U city were selected as final subjects for this analysis. It was found that a factor with the strongest effect on intention to prevent oral disease and preventive behavior among oral health belief was importance. In the study, it was identified that the parameters such as importance and benefit had a partial mediating effect on the intention to prevent oral disease and self-efficacy had complete mediating effect. Through these results, it seems necessary to develop an intervention program for middle aged people able to recognize importance and benefits of oral health by themselves in order to promote their oral health.

With the start of the present Korean Creative-Economy Government, more effort is put to prepare the Unification in many areas. But it is not easy to find studies on contemporary status of North Korea specifically in information technology or computer education due to the poor accessibility to the country. This study is on comparing computer education in elementary schools in North Korea and South Korea and diagnosing future direction of computer education as the beginning stage of Unification. The most study is performed from backtracking curriculum methodology based on computer textbooks from North Korea and South Korea. In both countries, the elementary school curriculum for computer subject is mostly dealing with the usage of softwares. In North Korea they don't teach internet applications and they uses different type of office programs. The further ideas for desirable future education are suggested with analysis on the computer education in other countries such as China and Vietnam which can be appropriate role models for North Korea and USA, UK and India for South Korea. It is expected in both countries that the computer education will be more focused on programming rather than on software usage in the future.

The purpose of this study was to develop an educational program designed to allow students to experience 'up-cycling' first-hand during class and understand its significance by helping them improving their practical problem-solving abilities. Teachers of home economics, Korean, and social studies to third grade middle schooler were asked to analyze the curriculums of their subjects. The analysis results were then used to identify common elements among the units, reconstruct the curriculums, and develop an integrated lesson program to offer integrated activities. Based on these, a lesson program was developed to make an eco-bag and running shoes under the theme of 'up-cycling' in the unit of 'environmentally-friendly clothing and mending of clothes' in the home economics subject. The results were as follows: First, a topical fusion lesson program was developed to integrate three subjects together. The development process involved the integration of the topic of up-cycling, a program model for integrated lessons, and a teaching and learning process plan for topical integrated education. Secondly, a lesson program for home economics was developed that was applicable to actual home economics lessons based on the topical integrated lesson program. The lesson domains were divided into large, medium, and small to create a ten-lesson teaching and learning process plan needed for the lessons, teaching materials that could be put to actual uses in lessons, and activity and evaluation logs for learners.

In addition to the rapid development of health information technology services for the development of new medical information, a lot of research is underway. Improve health care services for patients are many ways to help them. However, no information about the security, if only the technology advances in health care systems will create an element of risk and threat. Today's issues and access issues are stable over a public network. Ad hocsensor network using secure, non-integrated health information system's security vulnerabilities does not solve the security vulnerabilities. In the development and utilization of health information systems to be subject to greater restrictions. Different security policies in an environment with a medical information system security policy mechanism that can be resolved if people get here are needed. Context-aware and flexible policy of integration and confidential medical information through the resistance should be guaranteed. Other cross-domain access control policy for telecommunications should be protected. In this paper, that the caller's medical information system, diversification, diversification Security agent in the environment, architecture, design, plan, role-based security system are proposed. The proposed system architecture, design work in the field and in the utilization of one model are expected to be.

Even though, the Korean private Security Guard's industry is developing, it did not reached at the expected quality services because of the below cost tendering from flooded small security companies, consequently low pays and fragile benefits occur therefore, the skill level and morale decreased. Also, the private security guards field's education, training and development of expert certification system is not enough. One of the plans to solve these problems can be invigorate the certification system. The improving ways are suggested after the research and the analysis of the certification system as below. First, the qualification system to become a security leader will need to add directly related subject, skill examination and continuous refresh training. Moreover, it needs accurate needed the number of the securities and the reduction of the 1st examination exemption object. Second, the qualified system to be become securities will need to strengthen on standard of qualification and focus on skill evaluation, the job education need to state by the law, also exemption for applicant who approached requirements.

During the lateral x-ray testing of lumbar, in order to obtain the optimal image for diagnosis and to minimize the exposure dose, a glass dosimeter and spatial dose measuring meter was used to measure and evaluate the exposure dose and spatial dose distribution of each organs. The exposure dose of the organs have increased as they were closer to the X-ray tube and when the radiation field was completely opened, the exposure dose was increased. In addition, scattered rays have increased as the distance got closer to the subject and with the distance of more than 200cm, 95% of scattered rays was reduced. Such results can anticipate the exposure dose of patients during the lumbar x-ray test in the future and it can be proposed as a data for determining the testing methods and expected to be widely used as an important basic data for reducing the medical exposure dose.
