This descriptive study was conducted to identify the attitude toward euthanasia of EMT and nursing students and to compare their attitude before and after clinical practice. The convenience sample was comprised of 40 first grade and 40 second grade EMT students attended at G college in G-city, and 40 first grade and 40 third grade nursing students attended at C college in C-province. The variable was tested with an euthanasia attitude scale developed by Kim Ae Kyoung(2001). The valid responses were obtained and analyzed by using SPSS PC+ from November 25 to December 6, 2002. The results showed that most of the respondents agreed to have positive attitude toward euthanasia in terms of client's right and client's quality of life. Also, they thought that euthanasia should be legalized and the right to die with dignity should be guaranteed. The EMT respondents having a clinical experience showed significantly higher score than respondents having no experience in the subarea of medical ethics, and nursing respondents who had a clinical practice showed significantly higher score than others no experience in the subarea of quality of life. But, the other sub-areas had no significant difference between the respondents before and after clinical practice. The attitude toward euthanasia composed of sub-areas such as being after the quality of life, having a high regard for a life and recognizing client's right was not affected by the single factor of clinical practice. Therefore, much supportive intervention need to be done for the students about the significant affecting factors found in this study like a religion, values, education and observing experience of someone's death.

HTTP adaptive streaming has recently emerged to handle the rapidly growing traffic and to provide high quality multimedia contents. To improve the QoE (Quality of Experience) for HTTP adaptive streaming service, the average video bitrate should be maximized, and the video switching frequency (difference of bitrate between adjacent segments) and video stalling events need to be minimized. The recently proposed quality adaptation algorithms for HTTP adaptive streaming do not provide high QoE, since detailed QoE factors such as video switching frequency and bitrate difference of adjacent segments, are not considered. In this paper, we propose a SQA (Smooth Quality Adaptation) algorithm to improve the user QoE. The proposed algorithm provides the smoothed QoE, such that it minimizes the unnecessary video switching events by maintaining the quality in a certain period, thus minimizing the bitrate difference of adjacent segments. Through simulation, we confirm that the proposed algorithm reduces the unnecessary switching events, and prevents the sudden decrease in video quality.

Purpose - This study examined the relationship between service quality, perceived value, customer satisfaction and behavioral intention of coffee shop using CoffeeSERV scale. In this model, CoffeeSERV scale consists of fundamental characteristics, physical environment, confidence, beverage characteristics, and representation factors. In particular, this study tried to demonstrate the moderating effect of customer's regulatory focus orientation among in the relationships between service quality, perceived value, customer satisfaction and behavioral intention. Research design, data, and methodology - This study intends to expand the existing service quality research by using the coffee shop service quality measurement tool developed by domestic researchers. I wanted to find some implications for the trend. In particular, this study applied the regulatory focus theory to identify individual differences of customers regulatory focusing motivation. In order to verify several hypotheses, the data were 227 college students and analyzed with SPSS/PC 21.0 and SmartPLS 3 program. The moderating role of customer's regulatory focusing motivation was tested using multi-group analysis with SmartPLS 3 program. Results - The resutls are as follows. First, the fundamental characteristic factors only had a significant influence on the utilitarian value perception, but in the hedonic value perception, all other service factors except for the beverage characteristic had a statistically significant effect. Second, utilitarian and hedonic value had significant effects on customer satisfaction. Third, customer satisfaction had a significant effect on behavioral intention. Finally, the regulatory focus orientation played a moderating role in the relationship between beverage characteristic - utilitarian value, representation - utilitarian value, fundamental characteristic - hedonic value, physical environment - hedonic value, confidence - hedonic value, and utilitarian value - behavioral intention. Conclusions - The results of this study show that the various service quality factors that make up the CoffeeSERV scale have different effects on utilitarian and hedonic value. This means that perceived benefits from product and service experience have different impacts on the customer's experience. Therefore, marketers should identify the impacts of service quality dimension that customers who use coffee shops consider important, understand the impact process of these quality factors on experience value, customer satisfaction, and behavioral intention, and allocate limited marketing budget. The results also show that it is possible to establish differentiatied response strategies using customer's regulatory focus orientation to find ways to enhance utlitarian and hedonic value, customer satisfaction, and behavioral intention using various Coffeeshop service quality factors. At the end of this paper, some limitations and future research directions were suggested.

Recently HTTP (Hypertext Transfer Protocol) adaptive streaming services have been the subject of much attention. The video quality control scheme of conventional HTTP adaptive streaming services estimates bandwidth using segment throughput and smooths out the sample of segment throughput. However, the conventional scheme has the problem of QoE (Quality of experience) degradation occurring with buffer underflow and frequent quality change due to the fixed number of samples. In order to solve this problem, we propose a video quality control scheme based on segment throughput and buffer occupancy. The proposed scheme determines the number of samples according to the variation of segment throughput. The proposed scheme also controls video quality based on the threshold of bitrate to keep stable buffer occupancy. The simulation results show that proposed scheme improves QoE by preventing buffer underflow and decreasing quality change when compared with the conventional scheme.

Purpose: This study aimed to define the relationship among self-care, symptom experiences, and health-related quality of life(HRQoL) according to the severity of disease in chronic obstructive pulmonary disease(COPD) patients. Methods: The participants, 195 COPD patients, were recruited at a pulmonology clinic of a universityaffiliated medical center in B metropolitan city. Inclusion criteria were patients who were diagnosed as COPD and had less than 0.7 of $FEV_1$/FVC(Forced Expiratory Volume for 1 second/Forced Vital Capacity) ratio. The severity was classified with GOLD(Global initiative for Obstructive Lung Disease) stages, $FEV_1%$ predicted value from mild to very severe. The data were gathered by the medical records and self-reported questionnaires. Results: The self-care, symptom experience, and HRQoL were all significantly different by COPD severity based on pulmonary function(p<.05). There were significant moderate negative relationships between symptom experiences and self-care(r=-.54, p<.001) and between symptom experiences and HRQoL(r=-.64, p<.001). There was a moderate positive correlation between self-care and HRQoL(r=.63, p<.001). Conclusion: It suggests that the assessment of disease severity based on pulmonary function and subjective symptom experience in patients with COPD may be a key component to develop a tailored self-management program and to improve their quality of life.
