A researcher examined 158 medical technologists and 140 radiologists who are working at 9 general hospitals in Gyeongsangbuk-do area using structured questionnaire to find out degree of fatigue of health professionals, the primary factors that have effect on them, and actions to control their fatigue on December 1 through December 20, 2008. The average complaining rate of fatigue subjective symptom by syndromes was overall 17.24 points, and medical technologists scored 16.48 points while radiologists scored 18.09 points. There were significant difference in the average fatigue complaining score of both medical technologists and radiologists such as when the younger their age is, when they are single, when the lower their monthly salary is, when the shorter their total working period is, and when the current status is staff at work. As a result of multiple regression analysis which sets fatigue score as dependent variable, there were significant difference on both syndromes such as satisfaction on work, work stress, and sleeping condition. It was the highest on relaxation, which was 76.6%, among the 15 questions on actions to control fatigue, and the next was enough sleep and controlling stress. And the lowest was help from medical professionals, which was 7.3%. It was the highest on enough sleep, which was 1.98 points, and next was relaxation and controlling stress, and the lowest points were help from medical professionals and taking medicine in the effective score of fatigue control action. In consequence of research, it is necessary to develop program and health education to control health professionals' various fatigue such as stress management and sleeping, and it is considered to find out the plan about effective work system.

The purpose of the study was to provide the basic for the prevention of infection control by analyzing the level of recognition and practice of dental hygiene students. It is important for dental clinic staffs to know and practice infection control measures in favor of effective infection control. Thus, this study conducted an one-month questionnaire survey (during October 2008) for dental hygiene students who ever experienced in 16-week clinical practice, and analyzed total 206 questionnaire forms as collected from them, so that it could determine potential associations between their recognition and practice of infection control and thereby suggest an efficient solution for infection control in dental hygiene. 1. It was found that our students' recognition about infection control averaged $4.49{\pm}.58$ points on the whole, and they were best aware of instrumental disinfection and sterilization among other measures, which was followed by hand washing, extirpation control, post-sterilization management, personal protective outfit and instrumental surface maintenance respectively. 2. It was found that our students' practice of infection control averaged $3.85{\pm}.57$ points on the whole, and they practiced hand washing most actively among other measures, which was followed by extirpation control, post-sterilization management, instrumental disinfection and sterilization, personal protective outfit and instrumental surface maintenance respectively. 3. It was found that our students scored higher mean points in recognition about every measure of infection control than those in practice (t=15.676, p=0.000). Particularly, it was notable that there were significant differences between their mean points in recognition and practice of some infection control measures, such as instrumental surface maintenance (t=15.361, p=0.000), personal protective outfit (t=15.245, p=0.000) and instrumental disinfection and sterilization (t=11.169, p=0.000). But there was least significant difference between mean points in recognition and practice of hand washing (t=5.460, p=0.000). 4. For potential associations between recognition and practice of infection control, it was found that higher recognition was in significantly positive associations with higher practice in every measure of infection control (r=.478, p=.000), such as extirpation control (r=.630, p=.000), instrumental disinfection and sterilization (r=.477, p=.000) and post-sterilization management (r=.433, p=.000). 5. It was found that there were differences in our students' recognition depending upon availability of infection control guideline (t=4.587, p=.011), and there were significant differences in practice depending on necessity of infection control education on a statistical basis (t=2.229, p=.027). Overall, it is found that our dental hygiene students are very likely to practice hand washing and extirpation control, because both of these measures are relatively easy to practice or are considered legally binding.

The Purpose of this research was to assess food safety knowledge and perceptions on hygiene education among new owners of restaurant in Gyeongnam area. In the questionnaire survey to 462 new owners of the necessity of hygiene education, more than half of them(56.3%) answered ‘Needed’ while ‘So so(29.2%)’ and ‘No need(14.1%)’ were also not a few. For the questionnaire asked what educational area was most beneficial, ‘Restaurant management and service(53%)’ was the most selected followed by ‘Food safety management and briefing on relevant food safety regulations(20.1%)’, ‘Tax management(12.8%)’ and ‘Food culture and menu development(11.7%)’. According to evaluation on new owners’ food safety knowledge, total average score was turned out to 6.83(out of total score of 15), less than 50% of average correct answers, it signified the demand for quantitative and qualitative improvement on hygiene education. To view the three areas’ evaluation score, characteristics of foodborne illness(2.56 points, out of total 5 points) and general hygiene management(2.54 points) marked more than 50% of correct answers while critical control points marked only 1.73 points, the lowest score.

This paper proposes an integrated mobile sink networks management system which can monitor and control various kinds of wireless lan access points, located in many different areas divided by their managing groups, from multi-vendors, and their operations in networks. The proposed system has the center-local interoperability structure cooperating with local-center servers which can perform the same operations as the central servers for wireless lan access points from multi-vendors and wireless lan centric management features. For this purpose, we propose a new way of data design, messaging policy, and hierarchical system structure such that we can achieve stable and consistent management methods for various wireless access points on distributed networks.

It an inventory control system, the demand over time are often assumed to be independently identically distributed (i. i. d.). However, the demands may well be correlated over time in many situations. The estimation of reorder points is not simple for correlated demands with variable lead time. In this paper, a general class of autoregressive and moving average processes is considered for modeling the demands of an inventory item. The first four moments of the lead-time demand (L) are derived and used to approximate the distribution of L. The reorder points at given service level are then estimated by the three approximation methods : normal approximation, Charlier series and Pearson system. Numerical investigation shows that the Pearson system and the Charlier series performs extremely well for various situations whereas the normal approximation show consistent underestimation and sensitive to the distribution of lead time. The same conclusion can be reached when the parameters are estimated from the sample based on the simulation study.

Background: Due to lack of regular and systematic evaluation tool, Korea's tobacco control policy has not been examined its overall process of implementation including efficiency and adequacy of the policies. This study developed policy monitoring and evaluation model to assess policy implementation and effectiveness of tobacco control in Korea. Methods: Based on World Health Organization operational manual for assessment, MPOWER (monitor tobacco use and prevention policies, protect from tobacco smoke, offer help to quit tobacco use, warn about the dangers of tobacco, enforce bans on tobacco advertising promotion and sponsorship, and raise taxes on tobacco) related policies were reviewed by rating policy efforts, programme management, people (human resources and their development), provision of organization, provision of fund and partnerships (range, 0 to 5). Results: As a result of the experts' assessment, overall Korean tobacco control policies scored 2.61 points, which is poor. In relation to each 'MPOWER' policies, 'W' scored the highest points (2.93), followed by 'O' (2.91), 'M' (2.87), 'P' (2.86), and 'E' (2.23). 'R' scored the lowest points of 1.87, meaning government efforts in tobacco price policy is insufficient. Conclusion: This study concludes that Korean tobacco control policy should strengthen tax and price measures, while programme infrastructure, people, and funds for policy enforcement should be secured. Furthermore, rather than focusing on one specific measure, a balanced approach reflecting various aspects of tobacco controls should be considered in order to decrease smoking rates and prevent smoking initiation.

Although the uninhabitable islands are part of national property, those are not systematically managed and controlled in Korea. In this study, the positioning standards for uninhabitable islands are suggested with proper surveying methods. To establish the standards, the current status on managing the uninhabitable islands in foreign countries are investigated and analyzed. It was found that it is necessary to establish the ocean geodetic network based on a sound and systematic plan. In Korea, the ocean geodetic network can be established by combining the National control point and territorial sea control points. We suggested that one or two third or fourth control points are required to be established in total of 2,679 islands with connection to the 47and 249 first and second-order control points. It is expected that this network will provide ground control points for aerial and satellite images for large scale ocean mapping. In addition, close cooperation among the related departments such as Ministry of Construction & Transportation, National Geographic Information Institute, Ministry of Government Administration and Home Affairs, Ministry of Maritime Affairs and Fisheries, and Ministry of Environment is necessary for successful management on uninhabitable islands.
