This study takes an effort to suggest solutions for medical service consumers' sovereignty. Specifically, consumer evaluation, information seeking level, and affecting factors on information seeking level were explored in terms of medical service. In present study, medical information included medical institution and doctors, prescription, diseases, medical treatment and medical expense. Medical service consumers' information seeking is identified as consumers' own efforts to acquire medical information through various sources. The analysis results suggested that consumers' information seeking level is even lower, while their evaluation level is somewhat low. Moreover, the result for information seeking level by consumer characteristics implied that people who have high education, high economic status, medical knowledge, and high attitudes for consumer right are active information seekers. Finally, consumer attitudes for right appeared most influential factor on information seeking level, implying direction for medical service consumer education.

The objective of this study to investigate the satisfaction of elementary and middle school students in Chungnam province. We surveyed related to school food service, concerns about food ingredients and dietary life, perceptions of free school food service and satisfaction the quality and management of the school food service. Furthermore, this survey with the previous. Compared to year, frequency of education related to school food service and concerns about food ingredients and dietary life. Perception on free school food service increased 1.2%, not statistically significant. Satisfaction for the quality of the school food service statistically significant increase compared to 2015. ore individuals educated the foods' county-of-origin and a higher concern the food materials and dietary life, subsequently higher satisfaction for the quality and management of school food service. The results of this study suggest that concern and concentration on software of school food service such as education and guide are important.

By the newly emerging network access technology, we face the new heterogeneous network environment. Focusing on the co-existence of multiple access network technology and the complex service needs of users, the wireless service operators should present the stable service quality for every user. For this, the service operators should build the new operation framework which combine the pre-established network and newly adopted one. Our problem is finding the optimal heterogeneous network operation framework. We suggest market-based marginal cost function for evaluating the relative value of resource of each network and develop the whole new heterogeneous network operation framework. To test the applicability of developed operation framework, we build large-scale JAVA simulator. By this development, we can easily test the new network environment in practical engineering field.

Service Level Agreement (SLA) is a service providing scheme by a service class agreement between a user and a service provider SLA allows that a user can select an expected service class in various service classes provided from a service provider. Recently, SLA management is adapted to support the end-to-end Qos for service users in Beyond 3 Generation (B3G) networks. In B3G networks, SLA provides multiple service classes on access networks so that service classes should be managed to assure the service satisfaction for users. In this paper, we propose a dynamic Qos management scheme by IP traffic class controlling based on SLA in B3G networks. Also, to manage dynamic traffic service, we consider Differentiated services (Diffserv) mechanism for the resource management by SLA. An If service traffic class on SLA can be dynamically changed by Diffserv traffic management to support dynamic end-to-end Qos. Hence, in this paper, we consider the buffer threshold scheme for controlling traffic loads and the traffic level control scheme for implementing the dynamic traffic management by the SLA.

Purpose: The purpose of this paper are to propose a strategic map for hotel industry through analyzing the relationship between service resource, operational capabilities, and performance. Methods: A phone survey was conducted among Korean hotels, and 102 data sets were collected. Measurement items are assessed using both cognitive and objective scales. Results: As results, 'superior group', which is superior in both physical resources and human resources, is excellent in all capabilities and also in room occupancy rate. On the other hands, 'inferior group', which is inferior in both physical resources and human resources, shows lower achievements is in most areas except speed. In addition, physical superior group is better than human superior group in most capabilities except speed, but human superior group shows better results than physical superior group in both room occupancy rate and customer satisfaction. Conclusions: Through the empirical analysis, the conclusions attained are as follows; First, human resources affect customer satisfaction more directly that physical resources. Second, the balancing between physical resources and human resources has an importance to improve operational capabilities.

Supporting quality of service (QoS) guarantees for diverse multimedia services are the primary concerns for WiMAX (IEEE 802.16) networks. A scheduling scheme that satisfies QoS requirements has become more important for wireless communications. We propose a downlink scheduling scheme called adaptive priority-based downlink scheduling (APDS) for providing QoS guarantees in IEEE 802.16 networks. APDS comprises two major components: Priority assignment and resource allocation. Different service-type connections primarily depend on their QoS requirements to adjust priority assignments and dispatch bandwidth resources dynamically. We consider both starvation avoidance and resource management. Simulation results show that our APDS methodology outperforms the representative scheduling approaches in QoS satisfaction and maintains fairness in starvation prevention.

The current trend toward the utilization of the Internet as a common means for the offer of heterogeneous services imposes to address the issues related to end-to-end service assurance in the inter-domain scenario. In this paper, we first present an architecture for service management in networks based on service level specifications (SLS). The architecture is designed to be independent both of the specific network technology adopted and of the high level service semantics. Then, we focus on a specific functionality of the proposed architecture: Resource allocation in the multi-domain scenario. A distributed admission control algorithm is introduced, its complexity is evaluated and a comparison with related solutions is provided.

4차 산업혁명시대의 도래로 인해 현대사회는 과거와 다르게 경제, 경영, 문화 등 다양한 요소들이 변화하고 있다. 그 중 경영적 측면에서 나타나는 주된 특징은 유형재화 중심에서 무형재화 중심으로 변화하는 것이며 이에 기업들은 새로운 경영방식 도입, 제조에서 서비스로의 전환, 기술의 확장 등 혁신을 추구하기 위해 노력 하고 있다. 하지만 변화하는 시대 지속적 가치창출을 위해 가장 중요성이 높아지고 있는 인적자원에 관해서는 아직까지 단순한 방식의 전환에 머무르고 있어 실질적인 혁신을 가능케 하는 노력이 부족한 실정이다. 이에 본 연구에서는 서비스경제시대 새로운 인재상에 대한 기업에서의 활용성을 검증하고자 인재요소에 대한 중요성을 인식하고 기존 도출 된 서비스경제시대에 변화된 인재상 요소들이 조직문화와 조직구조의 유형에 따라 어떠한 관계와 차이가 있는지를 연구하였다. 최근 연구에서 도출, 검증 된 서비스경제시대 인재상요소를 활용하여 구성원들의 생각과 행동에 영향을 주는 요소인 조직문화와 조직구조의 유형으로 나누어 관계를 검증하였으며 그 결과 조직문화와 조직유형별로 유의미한 인재상에 다소 차이가 있었으나 두 가지 요소를 결합하여 해석하였을 경우에는 새로운 인재상이 모두 유의미한 것으로 나타났으며 이는 서비스경제시대 인재상이 실제 기업에 적합하다는 것으로 해석될 수 있다. 다만 본 연구의 지표가 한정적 이었다는 한계를 극복하기 위해 향후 다양한 요인들이 고려 된 표본과 체계화 된 조직유형 및 업종별 산업별 분류를 통한 연구가 지속적으로 이어져야 할 필요가 있다.

Nurses are critical human resources for the hospitals. However, in Korean hospitals, human resource management practices for nurses are not well established, and nurses' turnover rates are very high. Although the causes and tasks for shortage of nurses are analyzed, suggestions for the specific ways of HRM management practices for hospital managers are rare. In this article, the management challenges for nurses are discussed, and high commitment human resources management model for nurses are suggested. And future research directions and topics are suggested.
