Recently, HTTP Adaptive Streaming(HAS), a video streaming service over the HTTP based web platform has become common. The use of HAS service in mobile communication devices such as mobile phones and tablet PCs is rapidly expanding. This paper addresses ways to improve the quality of HAS service by enhancing the terms of viewer satisfaction. HAS systems have several internal operational processes, which can affect viewer satisfaction. Such processes include, the quality determination for the next video chunk, the TCP connections-setup procedure and the congestion control operation of the TCP. This paper proposes a transmission scheme to improve the HAS quality services over mobile web. The proposed scheme takes into consideration the past implicit communication state of the receiver's playback buffer occupancy. The results of these experiments indicate that the proposed scheme can improve the quality of HAS service from the mobile viewer's point of view.

최근의 공유경제(Sharing Economy) 비즈니스 모델의 중요성이 부각되면서 경제활동은 단순한 상품 매매에서 벗어나 복잡한 경험체험으로 바뀌고 있고 공유숙박(Sharing Accommodation)의 모델 또한 새로운 숙박 선택모델로 자리 잡았다. 본 논문은 고객이 공유숙박서비스를 체험하는 과정에 느낀 문제점을 고찰하여 공유숙박서비스의 최적화 전략을 제시함으로써 기존의 단점을 개선하고 고객만족도를 제고하기 위한 목적으로 연구를 진행하였다. 본 연구는 Airbnb와 Tujia 두 개의 공유숙박모델을 대상으로 비교 연구를 진행하고 참고 문헌 수집과 정리를 통해 숙박 공유연구 배경을 심층 분석하였다. 고객여정도(Customer Journey Map), 페르소나(Persona), 서비스 블루프린트(Service Blueprint) 등 서비스디자인 연구방법을 활용하여 고객 수요를 파악하고 서비스의 문제점을 발견함으로써 서비스를 최적화하는 방안을 제시하고자 하였다. Kano 모델(Kano Model)과 잠재적 고객만족 개선지수(Potential Customer Satisfaction) 등의 연구방법으로 검증한 후 세 가지 서비스 최적화 방안을 확정하여 서비스 시나리오(Service Scenario) 모형을 통해 최적화한 성과를 도출하였다. 본 연구의 결과는 공유숙박의 사업자 식별, 서비스 요소 개선과 보다 높은 수준의 고객 체험 제공에 도움이 되며, 더 나아가 공유숙박 시장의 건전한 발전을 촉진할 것이라 확신한다.

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.

In this paper, we propose the redirect streaming service model to enhance resurgent ability. The system consists of a redirect server, local streaming servers and clients. A redirect server searches the best streaming server. And streaming servers starts a requested service or resumes it when in a trouble. RTSP/RTP is one of the effective solutions to improve QOS in VOD, however a service can be broken off by an overloaded server or network especially in live. We designed and implemented not only a distributed streaming system that solves the broken-off service to enhance a resurgent system, but also DSSP, distributed streaming service protocol, which is adopted to implement this model. Those will improve the performance of streaming service using RTP/RTSP and be contributed to a real time streaming research to solve a service trouble.
