최근 개개인의 취향이나 특성을 고려하여 자동으로 사용자에게 정보를 찾아주거나 추천해주는 추천 서비스 시스템이 많이 개발되고 있다. 하지만 사용자의 상황에 따른 선호도를 고려하지 않을 경우 정확한 추천이 힘든 단점이 있다. 따라서 본 논문에서는 사용자의 상황에 따른 선호도를 고려하여 정확한 추천을 할 수 있는 필터링 방법을 제안하였다. 이를 위해 상황에 따른 사용자 선호도를 구하고 피어슨 상관계수를 이용하여 사용자의 상황별 오브젝트 선호도를 구하였다. 실험 결과, 기존의 서비스 시스템들과 비교하여 precision은 11%, 2%, recall은 8%, 4% 향상되었으며, 전체적으로 precision은 77%, recall은 53%로 나타났다.

Recently, delivery app services based on the O2O platform are increasing rapidly. Accordingly, various studies on O2O service have been conducted. Most of the studies are on consumer behavior in O2O services, and few studies on platform vendors have been conducted. Therefore, this study empirically analyzed the factors affecting the vender's intention to continuous use in the O2O delivery app platform service. Based on prior researches, we set the quality characteristics and network characteristics of the O2O platform as independent variables. The quality characteristics of the O2O platform consisted of system quality, information quality, and service quality, and the O2O platform network characteristics consisted of network externality and platform reputation. Perceived value and switching cost were set as mediated variables, and vender's intention to continuous use was set as dependent variables. For empirical analysis, we conducted a survey targeting vendors of O2O delivery app platform service, and conducted frequency analysis, factor analysis, reliability analysis, and regression analysis. As a result of the analysis, the quality characteristics of the O2O platform, such as system quality, information quality, service quality, and O2O platform network characteristics, showed that network externality and platform reputation had a positive effect on perceived value. The perceived value was found to have a positive effect on the switching cost and the intention to continuous use, and the switching cost was found to mediate the perceived value and the intention to continuous use. This study can contribute to the establishment of platform operation strategy as an empirical analysis on the factors that influence the intention of O2O platform vendors to use the platform continuously.

초고속 패킷 스위칭 네트워크에서 QoS 보장을 위한 여러 가지 방안 중 우선순위에 의한 패킷처리 방식이 선호되고 있다. 초고속 패킷 스위치에서 우선순위에 따르는 효율적인 패킷 처리는 서비스 성능 향상의 관건이다. 따라서 초고속 네트워크 내의 핵심인 패킷 스위치에서의 효율적인 우선순위 서비스 알고리즘의 개발은 중요하다. 본 논문에서는 효율적인 패킷 스위치 성능 향상 방안으로 큐에 대기하는 패킷의 개수에 따라 서비스시간을 가변적으로 할당할 수 있는 W-iSLIP 스케줄링 알고리즘을 제안하고, 시뮬레이션하여 기존의 알고리즘과 비교 분석하였다. 우선순위에 따른 서비스와 전체 지연시간을 분석한 결과, 전체 지연시간에 있어서는 2.6%, 우선순위 서비스에 있어서는 34.6%의 성능향상이 있는 것으로 분석되었다.

The correlations of nursing service satisfaction and subcategories of nurse's nursing activity styles were revealed a positive significant correlation; work difficulties management(r=0.17, p=0.03), effective work attitude(r=0.44, p=0.00), interpersonal relationship(r=0.51, p=0.00), keep regulation(r=0.44, p=0.00), professional values(r=0.31, p=0.00), professional development(r=0.30, p=0.00). 3. Stepwise multiple regression analysis revealed that the most powerful predictor of nursing service satisfaction was effective interpersonal relationship. A combination of effective work attitude, work difficulties management account for 38% of the variance in nursing service satisfaction of the patient in a hospital. In conclusion, this study revealed that the effective work attitude, interpersonal relationship, and work difficulties management in nursing activity were important factors to improve the level of nursing service satisfaction.

This research intends to explore two questions: 1) how the service qualities of trade exhibitions affect the participant's satisfaction, and 2) how participation motivation moderates the relationship's between the service quality and satisfaction. For this purpose, the service qualities were measured with respect to three components: 1) core services, 2) physical environments, and 3) personal services of trade exhibitions. The results showed that the core services had largest impact on the participant's satisfaction among three components. The influence of the personal services was next strong, and the impact of the physical environment was weakest. Participation motivation was shown to moderate the effects of core services and personal services on satisfaction, but its moderating impact on the relationship between physical environments and satisfaction was not observed.

The first thing to be prioritized is to set the scope of the management system when establishing an information security management system for systematic and effective information security management. It is important to set the scope for an organization's information security goals due to the scope affects the organization's overall information security activities. If the scope is set incorrectly, it might become impossible to protect important services and therefore, the scope of the management system should be determined in consideration of the core business services of the organization. We propose a core service selection model based on the organization's mission-critical service and high risk service in order to determine the effective information security management system scope in this paper. Core service selection criteria include the type of service, contribution to sales, socio-economic impact, and linkage with other services.

This research has classified waiting times into the three different ones according to service offering process and investigated the antecedents and consequences of types of waiting times. A service provider's concern and customer involvement were modeled as antecedent variables and negative emotion and service value as dependent variables. The empirical results of the study are as follows. A service provider's concern had significant influences on all the three types of waiting times whereas customer involvement was found to affect preprocess-waiting and postprocess-waiting times. Preprocess-waiting time had a significant impact on both negative emotion and service value and inprocess-waiting time only affects negative emotion. However, postprocess-waiting time had influenced none of the variables. The findings illustrate an important role of concern and involvement regarding to a customer's perceived waiting time and relative importance of waiting types on negative emotion and service value. A summary of the results are reported and managerial implications are discussed.
