Recently, third-party logistics and second-party logistics are well known as a form of logistics service. However, there are several opinions about the effectiveness of second-party logistics and third-party logistics. In this study, the efficiency of second-party logistics companies and third-party logistics companies, which are the main providers of logistics services, was compared and the sales impact on the logistics market was measured. Efficiency was measured using DEA's CCR and BCC models. Debt and equity were used as input variables, and sales, operating profit, and net income were used as output variables. As a result of measuring the efficiency of logistics companies, the efficiency of third-party logistics companies was higher than that of second-party logistics companies in 2019 and 2020, and it had a positive effect on the rate of change in sales.

Next generation telematics technology, offering new and diverse multimedia service by connecting car and wireless access network, has been presented with promising industry. Telematics technology was simply to monitor and control the in-vehicle devices and to navigate the road in the early days but nowadays, telematics technology has provided the mobile internet access service, LBS service, agent rescue service and multimedia service to us using connection of wireless access network. In this paper, telematics mobile platform architecture is proposed for service promotion and efficiency.

In this paper, we propose a real-time remote logging model for development of android applications using LBS(Location based Service). The model has two major parts: Mobile Log Management Service and Remote Log Server. Mobile Log Management Service consists of the log collector and the remote log manager. The log collector is an aspect of AOP which can collect logs from the target application without modifications of source codes. The remote log manager has a background service component so that it can receive logs whenever the log collector captures logs from the target application. Remote Log Server communicates with Mobile Log Management Service by socket interface. Therefore, Remote Log Server can show logs in real-time. To validate the efficiency of the proposed model, we show a case study, and compare the model with other models.

Decision makers in the service industry must effectively cope with queuing problems, service capacity optimization, service efficiency and service quality problems. This study proposes a computer simulation-enabled MCDM framework that integrates computer simulation analysis, Taguchi method, expert opinion and multiple criteria decision making (MCDM) to assist decision makers in coping with decision problems. In this framework, Taguchi method is adopted to reduce the time required for the simulation experiment. Computer simulation analysis is adopted to obtain useful information for rapid decision-making without interrupting actual production. MCDM is used to select the optimal alternative. The illustrative result is extremely promising.

Measuring and evaluating the business performance plays a very important role in managing business. It is both because business performance, in any types of industry, can be evaluated and managed properly only when the measurement of its performance is estimated and because its performance can be improved through an efficient and effective management. Therefore it is essential to build up the performance evaluation system to raise management efficiency of food service industry, to reinforce competitive power of food service industry. In this study, investigated the present performance evaluation system situation of the food service industry and introduced BSC as the main conceptional framework for evaluating the performance of the food service industry. Finally, this study discussed the possible method for building a balanced scorecard to the food service industry.

Under rapidly changing business surrounding, companies need information systems to keep their competitive powers and forecast business surroundings beforehand. In these trends, interests of ASP (Application Service Provider) service is increasing because of the advantage for efficiency to maintain a system and an inexpensive investment to build a system, and this service is rapidly spreading to many parts from simple functions to ERP system. In this research, we argue about these problems and about administrative framework technology for efficient ASP service of ERP system.

To cope with the rapid emergence of competition, communication service providers are assigning marketers for the purpose of relationship marketing. However, the efficiency of relationship marketing has yet to be examined. This paper investigates the service quality determinants In relationship marketing through the telecommunication service marketers. By considering the specificity of the marketer´s role, the quality dimensions in SERVQUAL research have been modified. A survey has been conducted for the hypothesized seven quality dimensions. The results of the factor analysis show that the service quality determinants of relationship marketing are in fact four dimensions : empathy, reliability, image and tangibles. Here, the empathy dimension entails cost factor, and the reliability dimension includes responsiveness and assurance. The results also support the proposition, reported in SIRVPIRF research, that the quality of service should be measured only by the perceived achievement of the customer. This study provides useful insights into developing the strategy for effective relationship marketing.

Service industries are rapidly increased and the environment of service is also changing in healthcare settings. Those make them change their management strategies and carry out many researches. Till now, single-item behavioral intention scale or direct measuring has some limitations that we have to consider its efficiency and it is difficult to explain phenomena of broad part in the process of determining behavioral intentions. In this paper, we examine the dimensionality of healthcare service in Korea through the multi-item behavioral intention scale. In addition, we are going to investigate the nature of the relationship between service quality perceptions which have unique construct, and consumer satisfaction judgements in the formation of consumers' behavioral intentions. we are going to conclude that the linear combination model of service quality and customer satisfaction can describe the process of formation of customers' behavioral intentions best and provide some managerial implications to decision makers for redistribution of materials and human resources.

The SMB supercomputing service provides a supercomputing infrastructure for Small and Medium-sized Business (SMB) to enhance the efficiency of product development activity. In this study, the economic value of SMB supercomputing service is presented. The economic value of service is comprised of a direct and an indirect economic value. A direct economic value was estimated based on the result of user survey on service effectiveness. The input-output analysis method was adopted to estimate an indirect economic value induced from a direct economic value. The future economic value based on the result of user demand survey is also presented. As a result, the annual and future economic value of service were estimated about 55,215 million won and 323,928 million won, respectively.
