Health belief is an important factor influencing the performance of health behaviors. Young adulthood is a critical period to establish health beliefs and behaviors for a healthy life. As health professionals, nurses can help young people establish more positive health beliefs and carry out health behaviors more effectively. But before attempting to help them, it is necessary to identify their health beliefs and behaviors. The purpose of this study was to identify the health beliefs and health behaviors of university students in Korea. Subjects for this study were 2000 students from 10 universities, but data from only 1605 subjects was included in the analysis. Data were collected from May 5th, 1998 to June 21th, 1998. Instruments used in this study were two tools to measure 'health beliefs' and 'performance of health behaviors' that had been developed and used in previous research. Cronbach's $\alpha$s were .8737 for the tool for health beliefs and .8385 for the tool for health behaviors. The results of this study are as follows. (1) Average score of the subjects was 117.68 for health belief and 95.15 for performance of health behaviors. (2) There was a significant correlation between the health belief and the performance of health behaviors(r= .419). (3) School year, major, health status, and experience of disease in the students were important factors in the explanation of health belief(28.8%). (4) Health belief, major, health status, school year, sex, age, experience of disease in family members were important factors in the explanation of the performance of health behaviors (21.2%).

This study aimed to evaluate conditions and performance of quality improvement (QI) activity in Korean dental hospitals. Twenty one representative dental hospitals in Korea were selected by the selection criteria. A questionnaire was implemented to measure awareness, perceived needs, educations, conferences, works, activating/obstructive factors and satisfaction related to QI activities. Satisfaction score range from 0 (lowest) to 5 (highest) among 329 dental hygienists who worked in the selected 21 dental hospitals. Implementation rate of programs on external customer satisfaction was the highest 59.9% in QI activities, and reduction of expenses (59.4%), Improvement in health care quality (58.7), risk management (52.8) were followed, while improvement in work efficiency (46.5) showed the lowest implementation rate. The most influencing factor accelerating QI activities was 'active participation of hospital workers' (54.7%), and 'effort to improve customer satisfaction' (44.7%) followed. The most influencing QI related obstructive factor was 'lack of QI-related manpower and support' (47.1%). A balanced development including QI programs with lower implementation rates is necessary. Encouraging participation of workers may be the most important in developing dental QI activities further.

This study was intended to assess the need of home nursing care and analyze the effect of home nursing care, and find out the problems during the performance of home nursing care for the chronic patients among the low-income people in urban area. Data collection by interview was carried out from Nov. 1991 to Jul. 1992. The main results were as follows; 1) Total subjects for the need assessment of home nursing care were 123 households wi th 488 persons in a urban poor area. Over half of households $(57.7\%)$ was teenage family. The overall living conditions were poor and the average monthly income was 580 thousands won. $74.8\%$ of subjects was covered by medical care insurance and only $4.7\%$ was covered by public assistance. The morbidity rate was $8.2\%$ among 488 subjects and $27.5\%$ of them was not treated at all, $30\%$ was treated in utilizing pharmacies or local clinics. 2) The subjects of home nursing care were 46 with Hypertension or DM who agreeded the participation of study among registered patients at a public health center in Incheon. Home visiting was performed at intervals per one month for one year. Most of them were the elder(mean age=61 years) and long term patients(7.8 years continued). Home nursing care was effective. That is, blood pressure(including systolic and diastolic pressure) was significantly reduced (t(n=22)=2.31, P=.031, t(n=24)=4.16, P=.000 respectively) and knowledge of disease(t(N=46)=-7.63, P=.000), attitude of disease (t(N =46) = -4.92, P=.000), and self-care(t(N =46) = -4.89, P= .000) were significantly improved through home nursing care. But there was no difference in blood sugar for diabetics between the beginning and the end of visits. At the beginning of visit for home nursing care, sex$(\beta=-0414,\;t=-3.012)$ and nursing need({3=.310, t=2.164) were influencing self-care, and duration of disease$(\beta=.297,\;t=2.106)$ and nursing need $(\beta=.385, t=20417)$ were influencing blood pressure, blood sugar level. Namely, the subjects who were male and had higher nursing need showed better self-care and the longer duration of disease and the higher nursing need were relationship with the better blood pressure and blood sugar level. At the end of visit for home nursing care after one year, the blood pressure and blood sugar level was influenced by age $(\beta.320,\;t= 2.242)$, duration of disease ($(\beta.352,\;t= 2.395)$ and nursing need $(\beta=.350,\;t=2.623)$ and self-care had no influencing factor. The higher age and the longer duration of disease and the higher nursing need were relationship with the better blood pressure and blood sugar level. 3) The problems that were found out during the performance of home nursing care were the absent of useful protocols for services and the clear evaluation base, and the difficulty of teaching elders who were the major part of our subjects.

Mineral electrical insulating oil, which is widely used in transformers, exhibits excellent cooling performance and transformer efficiency. However, given that it is composed of petroleum-based components, it is weak in terms of biodegradability. This causes environmental problems in case of leakage and a low flash point, which is a factor that would cause great damage in the event of a fire in a substation. In this context, the use of eco-friendly electric insulating oil composed of bio-based vegetable oil and synthetic ester, which has excellent biodegradability and flame retardancy performance, has recently been expanded to the field of electric power, and various research and development (R&D) studies are in progress. According to different research results, vegetable oil and synthetic ester manufacturing technology, thermal stability, oxidation stability, property change, and quality control, which are characteristics of eco-friendly electrical insulating oils, are major factors affecting the maintenance of insulating oil properties. In addition, power companies have established and operated quality control standards according to the use of eco-friendly electrical insulating oil as they expand the exploitatoin of renewable energy in electricity production. In particular, deterioration and oxidation characteristics were jointly identified in R&D as an important influencing factor according to the content of saturated and unsaturated fatty acids present in vegetable oils and synthetic esters in power transformer applications.

Purpose Recently, many organizations are actively adopting enterprise architecture (EA) as a methodology to manage IT assets and build IT-based business system. This study intended to empirically examine how the role of EA operating unit and utilization capability of organizational members impact on system performance at the post-adoption stage. A balanced score card (BSC) is being used as a framework for a company's key performance indicator (KPI). Design/methodology/approach This study tried to investigate the causal relationship between the four perspectives of the balanced scorecard as an influencing factor of the introduction of the Enterprise Resource Planning (ERP) on the financial value. In particular, the mediating effect between the customer's point of view and the business process point of view was investigated between the learning growth point of view and the financial point of view, and the interaction effect (regulating effect) of strategic linkage in the system introduction process was investigated. Findings The results of the study were first, that the organizational learning and growth perspective had a positive effect on the customer perspective, business process, and financial perspective. In addition, the customer perspective and the process perspective also had a positive influence on the financial perspective. Second, between the learning growth and financial perspectives, the customer perspective and the process perspective showed a partial mediating effect. Third, as for strategic linkage, the interaction effect between the customer perspective, the learning growth perspective, and the process perspective and the financial perspective was not significant. The results of this study are expected to provide a framework for performance evaluation to organizations that have introduced ERP systems.

This paper investigates the accuracy of the vehicle pre-braking speed estimated based upon measured skidding distance. Driver ordinarily takes sudden braking when urgent situation is developed in the front or when the driver is involved in an unexpected situation, and the driver may be inflicted upon an accident depending on the required stopping distance. Among factors influencing the stopping distance of vehicle such as recognition response time of driver, performance of vehicle's braking device, and state of road surface etc, pre-braking speed is seemingly the most important influencing factor. Currently, in the investigating section of traffic accidents, the state of overspeed is determined by the pre-skidding speed calculated based on the length of skid mark. In order to identify the accurate cause of the accident, it is strongly recommended that estimation of pre-braking speed should be estimated taking into account speed reduction during transient time. In this study, we propose a method for estimating more accurate exact speed information of vehicle at the time of traffic accident. The outcomes from this study potentially help better understanding of the characteristics of vehicle for traffic safety in the future.

The construction environment has the trend of oversizing and professionalizing, the increase of the construction period, and the risk factors and the uncertain factors which are important in the construction bid. The misunderstanding and the lack of knowledge of the subcontractor result in the decrease of the profit or the deficit. In conclusion, these are supposed to give the financial burden to the subcontractor. So, it is very important to predict the construction preparation cost calculation by the risk factors in the bidding stage and to calculate the bid unit cost considering the target profit of the subcontractor in the process of the mutual agreement and performance of the contract. In these points of view, this study analyzes how the importance of the risks influencing the bidding cost calculation affect the construction cost, and this analysis can be used as the basic data to establish the suitable bid strategy of the subcontractor.
