Socioeconomic status in this county progressed rapidly, this has brought about many changes in health care fields, namely, pattern of disease prevalence and morbidity, increase of the aged people, and also availability of health care in rural areas. According to the utilization study of medical care, it showed that the oriental medicine is used for the treatment of lasted chronic disease not the minor and common diseases which is quick in its effect. Particularly, in rural areas. prevalence of chronic disease is higher than that in urban areas. Although the health cafe need of the oriental medicine is high in rural areas, the distribution of manpower and facilities is lower than that in urban areas. Therefore the government has planned to implement the demonstration project for the oriental medicine at the designated 3 health centers in rural areas. The purpose of this study was to collect the utilization level of oriental medical care of the people in rural areas. To meet the purpose of this study, patient interview were applied. 790 patients visited to health center in project areas were selected and analyzed by experienced interviewers from 2 April to 21 April 1990. The major findings of this study were as follows ; 1) Of the 790 patients, 32.6 percent of the respondents had experience of using the oriental medicine. As for the utilization by age and sex. 54.8% of those was female and 70.7% was 40 years of age and more. 2) Reaction to the question of educational achievement showed that on schooling and primary school graduates accounted for 63.1%. 3) The most user of oriental medicine resides in country level, where the health center is located, and 80 percent of those users resides within 10Km. 4) More than 50% of the total was the chronic diseases which lingered for more than 3months. 5) 32.6 percent of the total cases used the oriental medicine. 61.2% among those was treated by oriental medical care hospital and 38.8% by oriental drug dispensaries etc. 6) The contont of oriental medical care varied ; 50.1% for prescription of herb drugs for treatment, 25.1% for health maintenance and 23.9% for acupuncture, moxibustion etc. 7) As for the motivation for using the oriental medicine. 56.6% of the respondents was for treatment of diseases and 27.9% wes for strengthening the physical weakness. 8) As for the effectiveness of the oriental medicine. 70.3% of the total cases satisfied with that treatment and 84.2% of the total cases will use the oriental medicine when is provided by health center.

The sandy beach along the east coast of Korea offers beautiful scenery with high-quality sand for leisure, and is also famous for the white-sand and pine-tree which is an important scenic resource. Furthermore, the sandy beach helps to maintain natural environment of the costal area and functionates as a disaster prevention system against high waves. There are two major value evaluation methods, Travel Cost Method and Contingent Valuation Method, to assess the value of coastal sandy beach. Contingent Valuation Method is considered to be more appropriate for simultaneous evaluation on the usefulness and the uselessness of the beach. But in order to apply Contingent Valuation Method to coastal sandy beach evaluation, close examination and investigation on the potential bias, such as on questionnaires, surveys and replies, are required. In this study, the characteristic of primary amenity of sandy beach users is investigated, in prior to evaluating the usefulness and the uselessness of the beach measured by contingent valuation method. The characteristic of amenity on major sandy beaches on the east coast of Korea is studied and compared by diverse value evaluation methods.

Objectives : In this study, the dental treatment satisfaction degree of the patients, who experienced the sleep dental treatment or non-sleep dental treatment, the revisit rate and the differences among the encouraging intention were compared and analyzed, and the primary factors through which the satisfaction degree of sleep dental treatment has influence on the revisits and the encouraging intention were analyzed, and the proposal was made on clinic management to raise qualitative medical service level on the basis of this study. Methods : The questionnaires filled out by the 202 users of a certain dental clinic located in Pohang-si, Gyeongbuk were analyzed. The frequency analysis and the crosstabulation analysis of the general characteristics of survey participants were carried out, and the satisfaction difference between the sleep dental treatment and the non-sleep dental treatment was identified with the t-test analysis. The multiple regression analysis were carried out to identify the factors through which the sleep dental treatment has influence on the through which the satisfaction degree of sleep dental treatment has influence on the satisfaction degree of the medical service and the revisited dentists. Results : In the medical service satisfaction degree in general, the sleep dental treatment had the higher meaningful value than the non-sleep dental treatment(p<0.05). In the case of the difference in satisfaction degree on each medical service factor, the satisfaction of the sleep treatment group was high in every case, but the meaningful difference showed up in the factors of waiting time, treatment procedure, revisit and the encouraging intention(p<0.01). The revisit to the sleep treatment dental clinic and the recommending dentist increased in proportion to the satisfaction degree of sleep dental treatment, and the Beta value appeared to be 0.337 at the influence of the subordinate variable(p<0.001). As for the influence on the sleep dental treatment satisfaction, the Beta value of the dental hygienist was the highest, marking the value at 0.375(p<0.01). As for the satisfaction of the patients who experienced the sleep dental treatment, the Beta value of the treatment fee was the highest, marking 0.352(p<0.001), in the multiple regression analysis of the revisit and the encouraging intention, and the 0.156 of dentist factor and the 0.152 of treatment procedure and waiting time showed lower regression coefficient(p<0.05). Conclusions : It is assumed that the satisfaction degree of sleep dental treatment, which is carried out as a new dental service has influence on the increase of revisit to the dental clinic as an important factor. But it was disclosed that the high level of treatment fee has the biggest influence on choice of revisit to the dental clinic. In the current medical charge system, the sleep dental treatment appeared to have a big influence on raising the quality of dentists, the satisfaction of patients, the revisit and encouraging intention, and also the roles of the dental hygienist was important. It is assumed that these facts are functioning as the factors that are linked to the increase of revisit and the encouraging intention.

The city of Suwon has introduced a dockless bike for the first time in Korea. In this study, a questionnaire was conducted for citizens to suggest improvement through satisfaction analysis. As a result of the survey, 88 % of respondents awarded the presence of a bike, and 90 % answered positively in terms of bike policy; whereas mature civic ethics showed an low satisfaction. For the purpose of usage, approximately 75 % of users mainly used for commuting, business, shopping, and the connection with mass transit. In the result of the primary means of a trip, a private car was most preferred before operation; However, it was found that mode transition has been actively carried out. This suggests significant implications for implementing sustainable urbanism. Meanwhile, The level of satisfaction significantly differed in the field of payment method, charge, usage guidance and publicity by an occupation and age groups commonly. Satisfaction in bike maintenance was statistically differed by an occupation. Satisfaction in Rental-return and registration procedures showed differences by an age groups. The results of this study will contribute to establishment related policies and to more activate dockless shared bike.

In recent years, unexpected bridge fire accidents have increased because of augmenting the number of traffic volumes and hazardous materials by the increment in traffics and distribution business. Furthermore, in accordance with the effort of using the under space of bridges, the ratio of occupied by combustible materials like oil tanker or lorry has been increased. As a result, the occurrence of bridge fire has been growing drastically. In order to mitigate the accident of bridge fire, risk assessment of bridge fire has been studied, however, practical risk models considering safety from users' viewpoints were scarce. This study represented quantitative risk assessment model applicable to national road bridges in Korea. The primary factors with significant impacts on bridge fire accidents was chosen such as clearance height, materials of bridges, arrival time of fire truck and fire intensity. The selected factors were used for Fire Dynamics Simulation (FDS) and the peak temperature calculated by FDS in accordance with the fire duration and fire intensity. The risk assessment model in bridge fire reflected the FDS analysis results, the fire damage criteria, and the grade of fire truck arrival time was established. Response plans for bridge fire accidents according to the risk assessment output has been discussed. Lastly, distances between bridges and fire stations were calculated by GIS network analysis. Based on the suggested assessment model and methodology, sample bridges were selected and graded for the risk assessment.

D2D communication as an underlaying LTE-Advanced network has proven to be efficient in improving the network performance and decreasing the traffic load of eNodeB(enhanced NodeB). However large amount of interference can be caused by sharing the resources between the cellular users and D2D pairs. So, a resource allocation for D2D communication to coordinate the interference is necessary. Related works for resource allocation that D2D can reuse the resources of more than one cellular user with best CQI(Channel Quality Indicator) have been proposed. D2D communications may still cause interference to the primary cellular network when radio resource are shared between them. To avoid this problem, we propose a radio resource allocation algorithm with low computational complexity for D2D communication in OFDM-based wireless cellular networks. Unlike the previous works, the proposed algorithm utilizes unused ones of the whole resource. The unused resource allocate to on D2D pair can be shared only with other D2D pairs. In other words, if the distance between the D2D pairs is sufficient, we allowed more than two D2D pairs to share the same resources. The simulation results have proven that the proposed algorithm has up to 11 times lower computational complexity than the compared one according to the number of D2D.

With the recognition of the importance of computational approach for protein-protein interaction prediction, many techniques have been developed to computationally predict protein-protein interactions. However, few techniques are actually implemented and announced in service form for general users to readily access and use the techniques. In this paper, we design and implement a protein interaction prediction service system based on the domain combination based protein-protein interaction prediction technique, which is known to show superior accuracy to other conventional computational protein-protein interaction prediction methods. In the prediction accuracy test of the method, high sensitivity($77\%$) and specificity($95\%$) are achieved for test protein pairs containing common domains with teaming sets of proteins in a Yeast. The stability of the method is also manifested through the testing over DIP CORE, HMS-PCI, and TAP data. Performance, openness and flexibility are the major design goals and they are achieved by adopting parallel execution techniques, web Services standards, and layered architecture respectively. In this paper, several representative user interfaces of the system are also introduced with comprehensive usage guides.
