This study examined the factors affecting the preference for the elderly's mental health services utilization in rural areas. A behavior model developed by Andersen and Newman provided an analytical framework to determine the factors affecting service utilization preferences among 335 elderly people as research subjects. The authors found that the preferences for mental health service utilization were significantly related to the level of education, living alone, presence of grandchildren, participation in social activities, and recognition about the services. Based on the findings, this study suggests that more mental health services for the elderly in rural areas be further developed and strengthened. Also, the elderly who lives alone and lives with grandchildren should have a priority in policy consideration. Multiple approaches are suggested to increase the awareness of mental health services and participation social activities for those older people.

Social security is concerned with ensuring all citizens maintain basic needs, community health nursing maintains and promotes health for all community members. Lately, This new area of community health nursing, concern social welfare has increased. The objectives of this study are, first, to analysis the activities of nurses at community social welfare institutes, second, to estimate nursing demand for social welfare areas. The study methods used were as literature review, an analysis of statistical data and case study etc. The analytical framework also included a demand analysis of nursing manpower in community social welfare areas. The major results are as follows; 1. Employees which work at social welfare institutes number 55,464, nursing manpower (including nurse aids) number 1,458 and this is 3% of the total employees. Within nursing manpower, nurses number 780, nurse aids number 670. 2. The rates of nurses among total employees were high in institutes for mental disorders and institutes for the age. 3. The salary level of nurses was lower than average and the rates of retirement showed a roughly middle level in welfare institutes. 4. The satisfaction level of nursing services was high, and it is the trend that nurses substitute for nurse aids which retire at social welfare institutes. 5. Nurse demand that follows legal criteria is 2,221, but only 35% are working. It is therefore insufficient from the minimum of 733 to a maximum 1433. 6. The sufficiency rates by institution were high at institutes for vagrants, aged and the handicapped. In conclusion, the conditions are of nurses which are working in with the social welfare institutes are poor. Also the number of nurses compared rates of demand were in surplus. But, the basic direction of welfare policy is universal-preventive and provision of the family and of community centered service, and nursing service demand in the social welfare institute will increase continuously, we predict. Therefore, we will need a positive plan such as the development of an inservice education program and the construction of an information collection system etc.

Promotion of immunization including early recognition of disease symptoms and effective control of communicable disease have been the important role of the school heath teacher in Korea. The school heath teacher as a nurse have been practiced vaccination for students as one of the major method for promotion of immunization in school. Recently it was occured difficulty for school vaccination that is practicing by school health teacher. So it is predicted for reducing of vaccination coverage rates of students. The objectives of this study are, first; to examine current guidlines of government, second, to analysis problem according to current guidline, third, to discuss further direction for school vaccination. There are used study methods as litrature review, analysis of statistical data and case study etc. Analytical framework for increased effects of vaccination in this study was safty, cost -effectiveness and coverage rates of vaccination. Major suggestions are as follows : First, It is different from the role of the public and private sectors in preventive health services. The preventive health services are characterized that the effect of health promotion is large, but the period of input effect is slow. Therefore the leading role of school vaccination should be have school and school health teacher including public sectors. Second, Health management of contemporary people can be effective with cooperative relationship between various health manpower. School health teacher as a medical manpower should be provide vaccination service continiously for health promotion of students. Third, It is necessary to maintain collective vaccination in school because have lots of advantage at safty, cost-effectiveness and coverage rates. In conclusion, school heath teacher should have central and independent role in school vaccination in according to current law. Also it will be assured lawful compensation in prepare to accident in vaccination.

Objectives: To investigate compliance of hypertension patients using modified Theory of Reasoned Action(TRA). Methods: The data were collected for 7-12 April 1997, by interviewing 190 Hypertension patients in Hwachon, Kangwon-do. The analytical techniques employed include contingency table analysis and logit analysis. Results: 15.1% of patients were unaware of the fact that he/she has hypertension and 11.2% did not know that he/she should take drug. 20.8% of patients took drug continuously, 20.1% had drug intermittently, and 53.1% had never have treatment. In the contingency table analysis, several variables were found to be significantly related to patient compliance. They included variables for attitude towards the consequences of taking drugs, normative beliefs, systolic BP at the enrollment, knowledge of how to take hypertensive drugs, variables for general health behavior and experience with having health worker's home visit. The logit analysis was performed by two steps. first step uses experience with drug treatment of hypertension as the dependent variable, and second step uses continuity of treatment. Included in the predictors that are significantly related to the former analysis are subjected norms produced by combining normative beliefs and motivation to comply, knowledge of how to take hypertensive drugs, and opinion about natural recovery of diseases. The only significant determinant of continuous treatment was knowledge of how to take hypertensive drugs. Conclusions: The results of analysis suggest the usefulness of TRA as a framework for the study of compliance of hypertensive patients. The findings have some practical implication as well. One is that efforts for enhancing compliance should be directed not only patients but also to other persons influencing patient's attitude and behavior. It also suggest that correct understanding of hypertension treatment is essential to perform the appropriate patient role.

Since the concrete covers most structures in modern architecture and it is composed of aggregates of about 75%, the appropriate selection of aggregates is valuable for the durability of concrete. A major cause of the expansion of mortar-bar measured by ASTM C 227-90 has been accounted by the alkali-aggregate reaction. This study carried out designed experiments on some aggregates including basalt and sandstone, to classify the expansion factors into the alkali-aggregate reaction, the increase of the gel pore volume, and the interstitial water that could expand physically the cracks or foliation developed in aggregates itself. The quantitative analyses of expansion by each factor indicated that the interstitial water and/or the alkali-aggregate reaction had major roles in the concrete expansion. Thus, if the supplied aggregates have deteriorated the structural framework, it is important to investigate the exact causes through this suggested method.

The Korean film market has rapidly achieved an international scale, and this has led to a need for decision-making based on analytical methods that are more precise and appropriate. In this modern era, a highly advanced information environment can provide an overwhelming amount of data that is generated in real time, and this data must be properly handled and analyzed in order to extract useful information. In particular, the preprocessing of large data, which is the most time-consuming step, should be done in a reasonable amount of time. In this paper, we investigated a big data preprocessing method for predicting movie box office success. We analyzed the movie data characteristics for specialized preprocessing methods, and used the Hadoop MapReduce framework. The experimental results showed that the preprocessing methods using big data techniques are more effective than existing methods.

The aerodynamic characteristics of vehicles are critical to assess vehicle safety and passenger comfort for vehicles running on long span bridges in a windy environment. However, in previous wind-vehicle-bridge (WVB) system analysis, the aerodynamic interference between the vehicle and the bridge was seldom considered, which will result in changing aerodynamic coefficients. In this study, the aerodynamic coefficients of a high-sided truck on the ground (ground case) and a typical bridge deck (bridge deck case) are determined in a wind tunnel. The effects of existent structures including the bridge deck and bridge accessories on the high-sided vehicle's aerodynamic characteristics are investigated. A three-dimensional analytical framework of a fully coupled WVB system is then established based on the finite element method. By inputting the aerodynamic coefficients of both cases into the WVB system separately, the vehicle safety and passenger comfort are assessed, and the critical accidental wind speed for the truck on the bridge in a windy environment is derived. The differences in the bridge response between the windward case and the leeward case are also compared. The results show that the bridge deck and the accessories play a positive role in ensuring vehicle safety and improving passenger comfort, and the influence of aerodynamic interference on the response of the bridge is weak.

This paper discusses a probabilistic method for power system security assessment. The security analysis relates to the ability of the electric power systems to survive sudden disturbances such as electric short circuits or unanticipated loss of system elements. It consists of both steady state and dynamic security analyses, which are not two separate issues but should be considered together. In steady state security analysis including voltage security analysis, the analysis checks that the system is operated within security limits by OPF (optimal power flow) after the transition to a new operating point. Until now, many utilities have difficulty in including dynamic aspects due to computational capabilities. On the other hand. dynamic security analysis is required to ensure that the transition may lead to an acceptable operating condition. Transient stability, which is the ability of power systems to maintain synchronism when subjected to a large disturbance. is a principal component in dynamic security analysis. Usually any loss of synchronism may cause additional outages and make the present steady state analysis of the post-contingency condition inadequate for unstable cases. This is the reason for the need of dynamic studies in power systems. Probabilistic criterion can be used to recognize the probabilistic nature of system components while considering system security. In this approach. we do not have to assign any predetermined margin of safety. A comprehensive conceptual framework for probabilistic static and dynamic assessment is presented in this paper. The simulation results of the Western System Coordinating Council (WSCC) system compare an analytical method with Monte-Carlo simulation (MCS).
