Providing explanations about recommending actions is one of the most important capabilities of expert systems. In fact, there exist many approaches incorporating this explanation facility into the system. Here we present briefly a new approach to generating these explanations and further attempt to investigate the impact of system explanations on user behaviors toward system-generated recommendations. For this experiment we designed a stock investment decision supporting system which, given a set of market situations, suggests an investment recommendation with explanations about the recommending action. Twenty-nine bank employees evaluated the output of the system in a laboratory setting. The results indicate that explanation facilities can make systems-generated advice more confident to users but cannot increase users'acceptance for the system conclusion.

The purpose of this study was to determine factors influencing patient satisfaction with medical services in hospital, which is classified into environmental aspect, human services and procedural services. Based on the results of literature review, the study focused on effects of social-demographical factors on patient satisfaction. The environmental aspect of medical care services included medical equipment and facilities, hygiene, ventilation, heating and air-conditioning, waiting and resting space, ward space and parking facilities. Procedural service included registration process, bill payment, waiting time after registration, examination and prescription as well as appointment process. Human services consisted of physicians listening to stories of patients, examination duration, physicians' explanation and physicians' service. As for nurses, explanation about disease, examination procedure and results, kindness and nursing care were evaluated. Services provided by other staff members were also evaluated. Patient satisfaction, defined as individual attitude toward medical service as a whole, was measured using a questionnaire. A total of 700 in-or out-patients were surveyed in 6 hospitals with more than 300 beds in North Gyeongbuk Province. 1. The level of patient satisfaction varied with characteristics of patients. Male patients and those in their 30s had a low level of satisfaction. Dissatisfaction level was positively related to education level but negatively related to economic condition. 2. As for patient satisfaction with medical service providers and other employees in hospital, satisfaction level with physician's explanation about treatment was higher. But dissatisfaction levels with treatment duration and the lack of explanation about examination procedures were high, calling for improvement. Dissatisfaction level with nursing care was high, calling for training of nurses for better service. Given the low level of satisfaction with human services, hospital employees need to be trained to improve their service. 3. It Was found that administrative service was also a significant factor influencing patient satisfaction in addition to medical service. It is therefore important for hospitals to provide patients with prompt and convenient procedural service. 4. Environmental factors such as medical equipment and amenity facilities also affected patient satisfaction. Thus environmental condition, procedural service and human service are all important to improve medical service in hospital. In summary, procedural service was the most significant factor for patient satisfaction. The level of satisfaction in patients was also affected by human service and environmental condition. It is therefore necessary to take patient-oriented approach in providing medical service in an effort to improve patient satisfaction. The finding of a lower level of satisfaction with human service signifies the need for training of healthcare providers and other hospital employees for better services. The introduction of advanced management programs is also needed to improve procedures that patients go through in hospitals.

Purpose: This study was conducted to determine factors affecting the positive feelings and care burden of elderly residents' primary caregivers in long-term care facilities. Methods: The survey was conducted between November and December 2018. A structured questionnaire was used to collect data, and 148 individuals voluntarily participated. The collected data were examined through descriptive statistical analysis using SPSS WIN ver.24.0, t-test, one-way Anova $Scheff{\acute{e}}$ test, Pearson's correlation coefficient, and multiple regression. Results: Factors that significantly affected caregivers' positive feelings included caregivers' education level(${\beta}=-.32$, p<.001), social support(${\beta}=.31$, p<.001), care burden(${\beta}=-.29$, p=.001), and total support fee(not more than 1.5million won)(${\beta}=-.18$, p=.012). The explanation power was as high as 40.0%(Adj $R^2=.40$). Factors that significantly affected caregivers' burden included social support(${\beta}=-.25$, p=.002), positive feelings(${\beta}=-.25$, p=.002), elderly individual's religion(${\beta}=-.17$, p=.007), and elderly individual's marriage status(${\beta}=.17$, p=.021). The explanation power was as high as 45.0%(Adj $R^2=.45$). Conclusion: Our results suggest that it is necessary to increase social support for elderly residents' primary caregivers in long-term care facilities. This can be helpful to decrease burden and enhance positive feelings in caregivers. We should also collect caregivers' information as well to provide appropriate assistance.

This study provides preliminary data to help organize improvements in analyzing the importance and performance of sanitation management items and the management of foodservice facilities in Community Child Centers in Daegu and Gyeongbuk Area. Questionnaires were distributed to 173 participants in sanitation and safety education at the center from April~June 2013 and 121 questionnaires were used as analysis data to investigate the management of foodservice facility at Community Children Centers in Daegu Gyeongbuk area. Most of the Community Child Centers are privately owned, and 62.0% had 20 to 29 children. Only 6.6% and 50.4% of the centers had nutritionists or cooks, respectively, due to budget deficits, and the foodservices were run by employees holding other positions. An investigation of sanitation management found that 84.3% of employees had a regular health inspection with significant differences between Daegu and Gyeongbuk (p<0.05). Most of the sanitation education was necessary, and the contents of sanitation education were applied to the fields in 66.1% of facilities. The reasons why the contents of them were not used in the fields included, the shortage of facilities and devices at 20.7%, which was the most common explanation. The separation separated of contaminated and non-contaminated areas were observed in 45.5% of facilities (p<0.01), separated sinks for pre-processing and cooking were found in 50.4%, and a show significant higher rate was noted in Daegu than in Gyeongbuk (p<0.05). An interior wall and, floor tile installation were observed 43.8% of facilities and a significantly higher rate was noted in Daegu than in Gyeongbuk (p<0.05). 30.9% of centers in Daegu and 11.3% of centers in Gyeongbuk area were equipped with a hot holding table(p<0.05). Overall, there is a need for education of foodservice to managers because most facilities do not have dietitians. In addition, facilities and equipment should be supplied continuously to foodservice facilities in community child centers.
