Purpose: The aim of this study is to identify the legal concept of a license and a qualification for health care personnel. We analyze the appropriateness of the qualification for the first-class paramedics and the sufficiency of 3-year job experience in substitution for college level academic major. Method: We reviewed Laws on Healthcare which stipulate academic and career qualifications for healthcare personnel for whom college-level academic training and job experience to get a license. Results: There is no legal consideration which permits major and educational background substituted by job experience. Only third-class hygienist who graduated from a high school or the equivalent with 3 year job experience can apply for first-class hygienist' national license examination without educational requirements. However, it is nothing to compare with first-class paramedics because the work of hygienist is not directly related to patients care and there is no need of doctor's supervision for hygienist' job. Paramedics have a major role in saving emergency patients in making prompt decision, applying appropriate emergency treatment, securing intravenous route, managing intubation, applying defibrillator, and etc. Conclusion: Ministry of Health & Welfare should grant license to paramedics and annul replacement of academic major background. In addition, it is imperative to broaden the scope of paramedics' job so that they can guarantee patient's life saving in emergency situation with quality major curriculum of college level.

Purpose: The purpose of this study is to understand nurses' perception of visiting nursing services of long-term care insurance. Method: The descriptive survey study involved 188 nurses selected by the convenient sampling of visiting nurses who participated in professional education sessions. Results: Of the 188 participants, 149 (79.3%) were aware of long-term care insurance. Awareness of aspects of long-term care services was 78.7% for facility service, 77.7% for ordinary visiting care service, 85.1% for visiting nursing service and 77.7% for visiting bathing service. Concerning visiting nursing service provision, the majority of the study subjects considered nurse-aid not to be the appropriate route for delivery of services including nasogastric tube exchange, tracheostomy tube management and stitch removal. Conclusion: Continuous evaluation and research on the standards and requirements of the nursing workforce is needed to secure and maintain the high quality of visiting nursing services. Exhaustive studies concerning task division and workforce separation according to nursing services type and level of difficulty should be done to develop the appropriate job description for visiting nursing service staff.

This study was conducted to investigate the correlations between the $PM_{10}$ concentration trend and meteorological elements in the Gimhae region and analyze the transportation routes of air pollutants through back-trajectory analysis. Among the air quality measuring stations in the Gimhae regions, the $PM_{10}$ concentration of the Sambangdong station was higher than that of the Dongsangdong station. Also, an examination of the relationships between $PM_{10}$ concentration and meteorological elements showed that the greater the number of yellow dust occurrence days was and the lower the temperature and precipitation were, the higher the $PM_{10}$ concentration appeared. Furthermore, a cluster analysis through the HYSPLIT model showed that there were 4 clusters of trajectories that flowed into the Gimhae region and most of them originated in China. The meteorological characteristics of the four clusters were analyzed and they were similar to those of the air masses that influence South Korea. These analyses found that meteorological conditions affect the $PM_{10}$ concentration.

The Purpose of this study is to determine the effect of new generation adolescents' clothing consumption values on their evaluation of clothing products. In the positive analysis, a questionnaire survey was conducted. Particularly, based on Sheth's (1991) theory, a focus group Interview was performed to develop the questionnaire on adolescents' clothing consumption values. The results of this study can be summarized as follows: First, young consumers have different values and clothing purchasing behavior from adults. To be specific, adolescents tended to appreciate fashionable and sensual values among clothing consumption values. Second, it was found that adolescents'personal values and their group-wise clothing consumption values affected their evaluation of clothing products. Such a finding may explain the relationship between value system and purchasing decisions. Namely, adolescents' evaluation of clothing products is affected by their value system. This finding supports the consumer value system suggested by the "expectation-value" theory. Thus, values and clothing products evaluation are neither separated from each other nor unrelated, but they affect each other in an abstract hierarchial structure. After all, through the route model, personal values affect clothing consumption values, which in turn affect clothing products evaluation. Besides, the clothing consumption values are affected by gender directly or indirectly. All in all, some specific indices regarding the abstract and hierarchial consumption values could be offered by analyzing the effects of adolescents' consumption values on their evaluation of clothing products in reference to the external clues of price and trademark manipulated, and thereby, the effects of consumption values on the positive clothing products evaluation could be determined in general.n general.

The heterogeneous fleet vehicle routing problem(HVRP) is a variant of the classical vehicle routing problem in which customers are served by a heterogeneous fleet of vehicles with various capacities, fixed costs and variable costs. We propose a new conceptual HVRPCR(HVRP with customer restriction) model including additional customer restrictions in HVRP. In this paper, we develop hybrid particle swarm optimization(HPSO) algorithm with 2-opt and node exchange technique for HVRP. The solution representation is a n-dimensional particle for HVRP with N customers. The decoding method for this representation starts with the transformation of particle into a priority list of customer to enter route and limit of vehicle to serve each customer. The vehicle routes are then constructed based on the customer priority list and limit of vehicle to serve. The proposed algorithm is tested using 8 benchmark problems and it consistently produces high-quality solutions, including new best solutions. The numerical results show that the proposed algorithm is robust and efficient.

MS-Contin is an oral controlled-release preparation of morphine sulfate that has been used widely in the management of advanced cancer pain. It prolongs plasma concentration of morphine with no observable accumulation properties following repeated dosing, thereby promoting uninterrupted sleep and hopefully improving patient's quality of life. The common side effects of MS Contin are nausea, vomiting, drowsiness and constipation. But these symptoms are usually mild and respiratory depression is a rare problem. We experienced respiratory depression during oral administration of MS contin for the pain management of advanced gall bladder cancer of 76 years old male patient with metastasis at liver, intestine and cervical lymph node. After we increased the dosage of MS Contin from 160mg to 220mg per day, due to abdominal pain, we observed morphine reaction of MS Contin overdose such as pinpoint pupil, deeply slow respiration below 8/minute, and drowsiness. After intravenous bolus injection of 0.4 mg naloxone followed by continuous administration of 0.2 mg/hr for 4 hours, the patient regained consciousness. The administered route of morphine was changed to intravenous PCA (patient controlled analgesia). There was no aspiration sign as confirmed by chest x-ray. The patient was comfortable and delayed no signs of respiratory depression until now.

In this paper, we proposed a mobile ad hoc routing protocol based on AODV(Ad hoc On demand Distance Vector) with QoS(Quality of Service) support and evaluated the performance through simulation. The waste of communication resources is reduced by establishing the shortest route suitable to QoS support, considering in advance the usable communication resources at each node. For performance evaluation, we analyzed the average data reception rate, considering the node mobility and the number of best effort/QoS data flows. We found that in the mobile Ad Hoc networks the QoS service for some specific data flows increased the average data reception rate for the QoS data flows.

Tactical network environments are characterized by unreliable connectivity, communication links which has limited bandwidth compared to commercial networks and distributed architecture where users have high mobility. The best route should be selected based on the required traffic characteristics which can be a wireless channel environments and a status of nodes which are moving. Those characteristics are self aware and should be a routing decision factor in order to guarantee a reliable data transfer. In this paper we define the requirements of services and traffic characteristics on tactical network environments and suggest the new routing method "AODV-IMTC" based on selective routing metric to enable efficient data transfer in wireless ad hoc networks.
