Recently, the geographic information system(GIS) is generally used in various fields with the development of information and communication technology, with expansion of its applications and utilization scope. Especially, utilizing GIS is expected to have positive effects on the geography learning and more helpful for the geographic information observation compared to the picture or 2D based media. The effective visualization of complex geographic data does not only take realization of its visual information but also increases the human ability in analysis and understanding to use the geographic information. In this paper, we examine a method to develop the geography learning contents based on the technology with augmented reality and GIS, and then we have a case study for various kinds of visualization techniques and examples to use in geography learning situation. Moreover, we introduce an example of the manufacturing process from the existing GIS data to augmented reality based geography learning system. From the above, we show that the usefulness of our method is applicable for effective visualization of the three-dimensional geographic information in the geography learning environment.

Purpose: X-ray exposure should be clinically justified and each exposure should be expected to give patients benefits. Since dental radiographic examination is one of the most frequent radiological procedures, radiation hazard becomes an important public health concern. The purpose of this study was to investigate the attitude of Korean dentists about radiation safety and use of criteria for selecting the frequency and type of radiographic examinations. Materials and Methods: The study included 267 Korean dentists. Five questions related to radiation safety were asked of each of them. These questions were about factors associated with radiation protection of patients and operators including the use of radiographic selection criteria for intraoral radiographic procedures. Results: The frequency of prescription of routine radiographic examination (an example is a panoramic radiograph for screening process for occult disease) was 34.1%, while that of selective radiography was 64.0%. Dentists' discussion of radiation risk and benefit with patients was infrequent. More than half of the operators held the image receptor by themselves during intraoral radiographic examinations. Lead apron/thyroid collars for patient protection were used by fewer than 22% of dental offices. Rectangular collimation was utilized by fewer than 15% of dental offices. Conclusion: The majority of Korean dentists in the study did not practice radiation protection procedures which would be required to minimize exposure to unnecessary radiation for patients and dental professionals. Mandatory continuing professional education in radiation safety and development of Korean radiographic selection criteria is recommended.

The research examines the characteristics of the sewing methods used for women's Jeogori in modern Korea. The results are following. In the 1920s sewing of shoulder parts was started, and in the 1930s sewing by hand had reduced by dissemination of sewing-machine, and in the 1940s the Som-jeogori declined by the matter of economic and sanitary issues. In the 1950s four-fold sewing emerged, and during the 1960s the gause-lined triple-layered Jeogori was in fashion, and in the 1970s the Ggaeggi-jeogori and much elaborated Jeogori became in vogue. The characteristics of the sewing methods are changed by following factors. First, the dissemination of sewing-machine in the 1930's enabled fast and precise sewing of Jeogori which reduced the rate of clothes mending and the production period. Second, by development of washing method, the dry cleaning became common, resulting cleaner washing and better preservation. Third, introduction of western clothes gave rise to modernized Han-bok which was changed into practical and simple one. Fourth, by the introduction of synthetic textile and industry development, Jeogori with no armhole line or right Seop line was made using wide selection of textiles. Fifth, in 1945~60s, women learned' good wife and wise mother' education and the use of sewing machine in school. The clothing lifestyle affected the sewing method's change, for example, clothes sewed strongly by sewing machine not to take clothes apart, and attaching button instead of Go-reum to save clothes.

As issues of education, employment and so on, the medical issue is one of the hot spots of society in China today. The health system reform which was pushed ahead after China's Revolution and open to the outside world hasn't received great progress. Many actual problems haven't been solved, for example it is difficult and expensive to see a doctor. With the development of the economy and society, the citizen's legal consciousness has gradually risen. They make a claim for better medical service. At the same time, the number of the disputes of medical care arises annually. China has sped up the opening of service trade for fulfilling promises of entry the WTO since 2001. China has already opened many service trade fields, including medical field. From the domestic perspective, there are many problems in domestic medical department. From the international perspective, China's present medical level falls behind the world advanced medical level. Under this background, it is a bold act for China to open the medical service field to foreign investors. Today, a huge medical service market is developed in China. However, the government's investment to medical devices and the financing channels is limited. Therefore, it is inevitable that individuals, social organizations and foreign investors invest to the medical market. In view of the situation, Chinese government issued a series of relevant laws and rules. In recent years, many multinational companies, consortiums, charitable institutions, enterprises and individuals establish various medical institutions in China. But there are rare research in the actuality and legal subject of foreign investment to Chinese medical market. Hence, it is necessary to realize the actuality of foreign investment to Chinese medical market, to familiar with the elements and procedure of establishing foreign joint and cooperative medical institution. Meanwhile, analyzing the existing problems and posing the legal subject have important theoretic and practical value.

We can agree that Quality Control in manufacturing industry have been improved successfully, but in construction industry, for example Sungsoo-Bridge broken out, Sampung Department store collapse, subway construction site explosion. and etc, it is difficult to be done. Because in manufacturing industry, they complete each other. If quality is not good. products aren't sold out. to sell more products they have to improve their products quality by themselves. However in construction industry they don't effort to improve quality if they get an order. Because if they get an order only completing their product is their job. There are engineering side, culturing side, and educational side to improve product quality. In this thesis I investigated evaluation system in construction industry. I am going to propose evaluation system by which they have effort to improve the quality even in construction industry.

In this study, learning materials that can be applied for web-based distant learning model were developed based on the characteristics of elementary school science in which investigation skills and thinking ability are considered to be important. And the effect of students' activity in a reports on student's investigating and thinking ability was investigated. While designing diverse experimental procedures, the students had. an opportunity to improve their observation attitude and way of scientific thinking. Such improvement was possible, only because the present web-based distant learning model consists of requiring an interaction between the students and a report and evaluation system which can put together such effort. Still, it was acknowledged that, as being in lack of teacher's direct support and supervision, the present web-based distant learning model might be somewhat ineffective in guiding the students in accordance with their own characteristics. For example, the students had a tendency to maintain their basic idea and style even when their reports are individually examined and corrected in terms of the format of the report.

It is important to guarantee the safety of vehicle to minimize the damage to the driver in case of the accidents. In order to inspect and later enhance the safety of vehicle, the owner of the vehicle usually have a vehicle safety inspection. The Korea Transportation Safety Authority (KOTSA) issues the Comprehensive Performance Inspection Certificate after vehicle inspection. The certificate only specify the legal inspection criteria for safety and measured values of the safety parameters, however, as ordinary driver in lack of expert knowledge about the vehicle is difficult to understand the contents of the Certificate. Thus, in this paper, the authors try to give the information about the inspection results in easier way to understand. This information not only guarantees the owner of the vehicle to better understand the inspection results, but it also gives the opportunity to the driver to deal with the specific problem listed in the results. The methods in this paper are to transform the vehicle inspection data into the non parametric distribution to easily represent the values to the index later on. Also, example indexes are presented to the actually inspected vehicle based on the reference distribution to show the better assessment of the developed method.

This study aimed to exploratorily investigate the new roles of libraries in the era of K-MOOC. For this, potential roles were derived and categorized from former researches and practices. And to evaluate the appropriacy of those roles, two expert surveys were conducted. Panel A was comprised of 30 professors who had been running K-MOOC classes and Panel B was comprised of 30 librarians of Universities that had adopted K-MOOC. The result shows that they both agree about distinct roles of library as information provider such as licensing and providing digital contents requested from information users, while technological part, for example, recording video and audio, managing website, and providing open access, was considered inappropriate because those roles were already taken by CTLs. Also, professors agree that information literacy education is required for teachers not just for students as the speed of technological development is too swift and librarians agree that they have to equipped with core competence in preparation for upcoming change by creating added value, establishing closer relationship with various educational and technological institutes, and securing organizational flexibility.

This paper proposes a conceptual model for distributed problem solving(DPS), where cooperation and communication among agents are based on virtual shared memory (VSM) In this model, all agents in a DPS system view all the memory in a distributed computer system as a single shared memory in which data, tasks, and results can in a distributed computer system as a single shared memory, in which data, tasks, and results can / be accessed by any of the agents. Several agents cooperatively solve a complex problem, as agents write data, intermediate results of execution, and tasks requested to other agents to VSM and other agents read or execute them. Also, in order to develop DPS systems based on the proposed conceptual model, this paper designs a DPS system development environment(DPS-VSM)using Network Linda. Thi spaper shows utility ofthe proposed model by presenting an example of simulation a VSM-based DPS system, and analyzes the model by comparing the features of DPS- VSM with some other DAI programming shells.
