Objectives : The purpose of this study was to examine factors affecting the effective demand of workers for dental treatment in a bid to provide some information on the improvement of oral health. Methods : The subjects in this study were 255 workers who were engaged in the pharmaceutical industry. A self-administered survey was conducted, and the collected data were analyzed by a spss(statistical package for the social science) win 12.0 program to find out their demographic characteristics, oral health awareness, oral health behavior and factors for the choice of a dental institution. Results : 1. Concerning the level of oral health awareness, 47.0 percent were at a low level(0 to three scores), and 35.2 percent were at an intermediate level(four to six scores). 2. As to oral health behavior involving a daily mean toothbrushing frequency, they brushed their teeth 2.65 times per day on the average. The most widely utilized oral hygiene supply was mouth rinse. Regarding oral health status, 53.7 percent weren't in good dental health, and just 23.0 percent got a dental checkup on a regular basis. 45.8 percent of those who didn't get a dental checkup cited time constraints as the reason. 26.0 percent received oral health education, and 91.4 percent were aware of the necessity of a corporate incremental dental care system. 3. Marital status, age and the reliability of dental institutions made differences to their choice of a dental institution. 4. As for the relationship between oral health awareness and the factors for the choice of a dental institution, oral health awareness had a statistically significant positive correlation to the reliability of dental institutions. Conclusions : The above-mentioned findings suggest that oral health education enables workers to have a correct knowledge on oral health, to change their own oral health behavior and to make the right choice of a dental institution in consideration of their oral characteristics. They should be urged to get a regular dental checkup not to develop chronic oral diseases so that they couldn't have to receive first-aid dental treatment. To promote the oral health of workers, oral health care personnels available should be utilized, and the incremental dental care system should be more vitalized to cut down on their effective demand for dental treatment.
Many organizations have been recognizing the necessity of workflow automation technologies according to the rapid expansion of business process oriented applications, such as enterprise resource pianning, customer relationship management, electronic approval management, and so on, Thus, they have started adopting workflow management systems as an essential technological solution for their workflow processes, However, we need some technological extensions and improvements on them in order to accommodate a new type of workflow processes, which is called cross-organizational global workflow processes that require a certain level of collaborations between the organizations engaged in the global workflow processes, Fragment-driven workflow modeling methodology is a Bottom-Up methodology composing a global workflow by defining each organization's own activities, which is called a fragment through a realtime cooperative system. The approach is able to not only simplify the modeling work but also keep each organization's independence in modeling a global workflow, In this paper, we describe the fragment-driven workflow modeling methodology and realize the methodology through the implementation of a cooperative swimlane workflow modeling system.
Domestic market of mass catering establishments has been increased greatly since early 90's with the emergence of professional mass catering business and the expansion of school food service. Because of the characteristics of mass catering establishment, feeding many people at a time, there is always a high potential of foodborne outbreak which requires special sanitary management to prevent. Large-scale outbreaks occurred last few years in Korea revealed the necessity of establishing strong safety measures for the sanitary management of mass catering establishments. Currently, many catering businesses are interested in Hazard Analysis Critical Control Points(HACCP), a new sanitary management system, and are trying to implement HACCP for their food services. Korean government is also undertaking model projects for mass catering establishments. Accordingly, numerous efforts are being given to dove op HACCP plans by the academia and industry, however, there has been no report on generic HACCP model which can be used directly for mass catering establishments dealing with numerous menus. Therefore, this study suggested a methodology to develop HACCP plans for domestic mass catering establishments and a generic HACCP model which can be applied to most Korean mass catering establishments hoping to implement HACCP system.

As the necessity of land information has increased according to development of computer and Information-communication, people have been interested in the satellite measurement system that can update Cadastral and Geographical information rapidly and exactly. Most Cadastral base points which had limitation of measurement technology in the 1910s were less accurate and were destroyed through the Korean War. They also many problems in the process of reinstallation. So, they require the quick and correct method of measurement in re-equipment of a base point and a parcel based survey and so on. This study intends to present the GPS survey direction by understanding and analysing all sorts of problems rising in case of applying the GPS to cadastral area in order to increase the efficiency of the GPS measurement, and also develop the GPS kinematic survey program to apply to the efficiency of a kinematic survey. As a result of research, I could confirm the accuracy of Cadastral base points in Kwangju area by using Korea GPS array and a base point, and could get the result similar to existent cadastral survey result with the coordinate conversion program of Cadastral technology research institute. We however have to pay our attention to the transformation of the plane coordinates because the difference between tens of cm and the existing result can outbreak according to the Gauss conformal double projection method. And, I could figure out the practicality of the developed GPS kinematic survey program, compared with common use program. I expect that it can be applied to the digital cadastral survey and the cadastral map renewal as well.
Research is being made for users' convenient access to services such as personalized data and contents services. The use of information and the fusion of services in various devices and terminals suggest the necessity to know what personalization mechanism is used to provide high quality contents at a time and place desired by users. Existing mechanisms are not easy to be handled by other service providers because each service provider has different preference and personal information, and are very inconvenient because service users have to set up and manage by themselves. Thus, the present paper proposes a Semantic User Profiles Manager based on OSGi, middleware for the provision and extension of semantic services, in order to manage users' profiles dynamically regardless of service provider. In addition, this paper defines a personalized semantic profile that enables user profiling, ontological domain modeling and semantic reasoning. In order to test the validity of this paper, we implemented semantic profiles into a bundle running based on OSGi. When users enter the range of the service area and use various devices, the semantic service matches in correspondence with semantic user profiles. The proposed system can easily extend the matching of services to user profiles and matching between user profiles or between services.

In this study, an algorithm to predict evacuation routes in support of shipboard lifesaving activities is presented. As the first step of algorithm development, the feasibility and necessity of an evacuation route prediction algorithm are shown numerically. The proposed algorithm can be explained in brief as follows. This system continuously obtains and analyzes passenger movement data from the ship's monitoring system during non-disaster conditions. In case of a disaster, evacuation route prediction information is derived using the previously acquired data and a prediction tool, with the results provided to rescuers to minimize casualties. In this study, evacuation-related data obtained through fire evacuation trials was filtered and analyzed using a statistical method. In a simulation using the conventional evacuation prediction tool, it was found that reliable prediction results were obtained only in the SN1 trial because of the conceptual and structural nature of the tool itself. In order to verify the validity of the algorithm proposed in this study, an industrial engineering tool was adapted for evacuation characteristics prediction. When the proposed algorithm was implemented, the predicted values for average evacuation time and route were very similar to the measured values with error ranges of 0.6-6.9 % and 0.6-3.6 %, respectively. In the future, development of a high-performance evacuation route prediction algorithm is planned based on shipboard data monitoring and analysis.

To comprehend the importance and necessity of record management metadata standard implemented in an electronic medical records system, a survey was undertaken to 50 medical records managers in charge of 5 major hospitals in Seoul. Analysis of the survey results was performed by averaging the responses given by those who answered the survey. SPSS was utilized for statistical analysis. Managers of medical records placed importance on metadata that are related to security of records, such as "levels of security", "types of access to medical records", "levels of authorization granted to personnel", and "users accessing medical records". It shows that these managers need the functions of privacy protection in ERMS. Metadata on "external disclosure" had the lowest level but those surveyed with more than 7 years of experience placed greater importance in this area more those surveyed with less than 7 years of experience in a hospital. This shows that managers need the functions of external disclosure to meet the needs of third partiesfor medical research and medical education.
Double Stack Train(DST) is being used variously around USA and Canada. The greatest advantage of the DST is mass transportation without extending the length of freight train and number of cars. So the DST system can be a kind of innovative train to increase the competitiveness of rail logistic business. As the domestic rail logistic increase, for enhancement of environment friendly green transportation amount, the DST needs more for efficiency. In this study, as the alternative way to introduce the DST to the Kyungbu Line, it's investigated the extensibility of rail freight with the relation of rail fare discount and examined the necessity of pilot business to the Kyungjeon Line which was expected comparatively lower cost. If the DST system is introduced to the Kyungjeon Line, the cost of mass transportation can be much lower and then the comparativeness of rail transportation will be increased, therefore logistic companies can have some margin additionally. In the result of survey to the related companies, if rail transportation fare is 37.7 % cheaper than current road transportation fare, the modal shift can be transferred by maximum 100%.
The purpose of this study was to evaluate the difference in perception of clinical nutrition service (CNS) between doctors and dietitians working in hospitals in Busan and the Gyeongnam area. Research was performed through questionnaires (from November to December 2011) at over 100 beds. 73.3% of dietitians were aware of the Nutrition Support Team (NST), while only 15.6% of doctors were aware of it. Due to heavy work and lack of medical staff, doctors didn't participate in NST, although most of them recognized the necessity of NST. 61.7% of dietitians screened and managed malnourished patients, whereas only 29.8% of doctors did. The main reason dietitians didn't treat malnourished patients was the absence of a treatment system in the hospital. Less than 50% of dietitians participated in the doctor's round to malnourished patients. As for why dietitians didn't participate in doctor's rounds, 71% of doctors chose understaffed dietitians and 38.1% of dietitians chose the doctors' unawareness of the importance of the dietitian in doctor's rounds. For the lower rate of nutrition counseling in provincial regions, compared to the capital region, 46.8% of doctors cited a lack of connection between doctors and clinical dietitians, while 43.3% of dietitians cited the lack of doctors' awareness on the importance of nutrition counseling. Although 87.3% of the doctors and 91.6% of the dietitians answered that CNS is important for treatment, the perception of onsite performance status on CNS was found to be low in both groups. 48.9% of doctors and 50.0% of dietitians regarded dietitians in the hospital as personnel in charge of food services, rather a member of the medical team. To improve the awareness of the importance of the CNS, and the image of clinical dietitians, 31.2% of doctors answered "to introduce a professional dietitian license for each disease" and 26.7% of dietitians answered "to change the system in the hospital". Most subjects found that a separation of clinical nutrition services from the food service part is needed. These results suggest that it is important to narrow the difference in perceptions of clinical nutrition services between doctors and dietitians for an organized clinical nutrition management of patients in hospitals in Busan and the Gyeongnam area.

Recently, as the needs of developing the micro autonomous underwater vehicle (AUV) are increasing, the acquisition of the elementary technology is urgent. While they mostly utilizes information of the forward looking sonar (FLS) in conventional studies of the local path control as an elementary technology, it is desirable to use the obstacle avoidance sonar (OAS) because the size of the FLS is not suitable for the micro AUV. In brief, the local path control system based on the OAS for the micro AUV operates with the following problems: the OAS offers low bearing resolution and local range information, it requires the system that has reduced power consumption to extend the mission execution time, and it requires an easy design procedure in terms of its structures and parameters. To solve these problems, an intelligent local path control algorithm based on the beam modeling of OAS with the evolution strategy (ES) and the fuzzy logic controller (FLC), is proposed. To verify the performance and analyze the characteristic of the proposed algorithm, the course control of the underwater flight vehicle (UFV) is performed in the horizontal plane. Simulation results show that the feasibility of real application and the necessity of additional work in the proposed algorithm.
