Modern society can be described as ubiquitous computing over the concept of information. Information technology(IT) has been developing in a way that relative technologies are integrated to each other. Especially in ubiquitous environment, medical information industry shows significant interest in the U-healthcare service area. This paper will first look into U-healthcare service environment and component of Integrated Medical Information Systems(IMIS). Secondly, it examines the basic technological factors for integrated medical information systems, which is datawarehouse, network, communication standards and technology related U-healthcare service. Finally it proposes how to implement and operate new integrated medical information system for ubiquitous health care service. The system will do point of care(POC) for customers by real time and diagnose them using their various and personal medical data. The information will be communicated back to the customers, which will improve their satisfaction.

In this paper, we attempt to investigate the factors influencing usage and acceptance of ubiquitous services in campus, based on the Technology Acceptance Model(TAM). This study conceptualizes and develops three dimensions of u-Services, such as real time service, information security, customization service, and tests the relationship among u-Services, perceived usefulness and perceived ease of use, and intention to use. Data were collected from 162 respondents in K-University and research model was tested using multiple regression analysis. As a consequence, this study found that customization service is an important factor which is influenced to perceived usefulness and perceived ease of use.

Although u-healthcare service is emerged as an alternative method for effective chronic disease management services, the service has not yet been applied for real healthcare setting. The objective of this study is to explore the doctors' perception and influential factors on intention to use u-healthcare service. We conducted survey for physicians about u-healthcare service provision to compare characteristics by different groups. In addition, logistic regression analysis is conducted to find out factors affecting the usage intention. As a result, doctors responded only 16.0% of total respondents had experience of u-healthcare services, but also showed that as high as 70.1% had intention to use service. Also, respondents answered that u-healthcare services is appropriate to apply for chronic disease prevention and diabetes and hypertension are suggested as the most appropriate diseases in order. The intention to use the u-healthcare service by non-university hospital doctors was 3.7 times higher than university hospital doctor. This study shows that identifying the differences of doctors' awareness and also the intention to use about the u-healthcare services will contribute to develop more effective business model.

The development of the Information Technology(IT) has brought enormous change to the human life, not even only to the politics, economy, society, and cultures, but all the way through the people's consciousness and cultural patterns. However, the information society resulted information inequality issues and especially to those disabled people, who have more difficulties on the technology adaptation, the "digital divide" symptom is significantly found. At present the rapid development of IT has gone beyond the level of the information society and it is accelerating the ubiquitous society that will combine people, computers, and all objects into one. And during the time of ubiquitous the "digital divide" will still exist. This research is focused on the digital divide of disabled people that were insufficiently covered in the research of digital divide and ubiquitous. From the empirical study of the effect that the disabled contributes on the service usability in U-City, the factors of background of the digital divide, and the difference of such factors in types of sex, ages, disabled types, and disabled class, and finally how the ubiquitous divide of the disabled affects have been researched. Based on the proposed study model and by analyzing the model by structural equation, following resulted was gained. (1) With the TAM (TAM : Technology Acceptance Model), which is commonly used in the studies of IT devices and services, the digital divide of the disabled cases cannot be identified sufficiently since it is not eligible for Using Intention of U-City Services. (2) In case of the disabled, the mental factors like willingness to overcome the impediment and accessibility like environment to meet the information services and ability to access the services are more effective on Using Intention of U-City Services rather than TAM.

Recently, the government aims to discover and provide services to citizens on the development strategy for activating the U-City. So, this study aims to offer a service discovery direction by analyzing the service issues and trends. The target is newspaper article about U-City Service from 2009 to 2014. Prepared 723 newspaper article for analysis. Next step is frequency analysis of keyword and used that result for Network analysis and measure of information. Network analysis can show result through "Degree Centrality", "Betweenness Centrality" and "Closeness Centrality". As a result, "Information", "IT", "Environment", "Technology", "Center" is higher than another. These 5 keywords are important factors for driving the U-City the past six years. Information measurement results, Already U-City were put an emphasis on building the infrastructure and able to identify a trend that provided the center of the public service. Those Service field are "Tour(2009)", "Crime prevention and Disaster Prevention(2010)", "Facility Management(2011)", "administration(2012)" and "Facility Management(2013, 2014)". Result of this study found implications what on citizen participation. So, services field on the existing infrastructure should be discovered and provided. Finally, this study can expected to be a reference in the local government planning for U-City.

This study investigates responses to privacy concerns by analyzing the psychological and behavioral characteristics related to the disposition toward invoices of courier service users. To this end, we develop a theoretical framework by combining stimulus response theory, communication privacy management theory, the theory of reasoned action, and the theory of planned behavior. Based on the theoretical framework, we analyze the relationships between social influence, privacy propensity, privacy control, privacy risk, privacy concern, invoice disposition intention, and invoice disposition behavior in the context of courier services. To test our hypotheses, we survey courier service users in the U.S. and Korea. Using a structural equation model, we test the relationships among these various factors for the courier service users of the two countries. Results have distinct implications for the psychological and behavioral characteristics concerning the disposal of courier invoices and enable understanding of the characteristics of courier service customers of the two countries.

The purpose of this study aims to confirm the importance of customer selection attributes of beef restaurants. This study found a selection attributes for a beef specialty restaurant, and proved the hypothesis through empirical analysis. Along with the increase in income levels over the past decade, the restaurant industry has grown. In contemporary society, where quality of life is becoming more important, the restaurant industry has expanded the importance of service quality. In particular, for meat consumption, per capita beef consumption is expected to increase every year; the effect of the Korea-U.S. Free Trade Agreement is also expected to further increase the consumption of high-quality and high-priced U.S. beef. However, like the study of general restaurant-selection factors in restaurant management research, studies of beef restaurants and commercial studies considering consumers' selection attributes are scarce. This study verified the characteristics of consumer choice for restaurants specializing in beef, and how quality, price, restaurant atmosphere, and employee service impacted customer satisfaction. We suggest that beef restaurants should focus more on atmosphere and service in addition to food price and quality, which are the choice factors for restaurants in general. This study empirically verified the importance of selection attributes, providing theoretical and practical implications.

Conventional studies on technology acceptance have focused on information technology for utilitarian value and hence based on 'theory of reasoned action'. Correspondingly, the studies depend on perceived usefulness and perceived ease of use as rational decision making elements. However, in ubiquitous society, innovative technologies are applied to non-task area, as well as task-oriented area. Therefore, users are more influenced by affective factors than cognitive factors in causing their usage intention. In line with those discussions, we cannot make sure that the conventional technology acceptance model could fully explain the current u-service acceptance phenomenon. Hence, to overcome the limitations of the prior technology acceptance studies, we propose an amended TAM which includes one hedonic factor and two factors on ubiquitous computing technology : ubiquity and intelligence.

In this country grassed waterway practice has long been employed for the protection of drainage or diversion ditches in treating the sloped forest lands. However, the hydraulic characteristics of flow in the ditches have been entirely away from consideration in determining the dimensions of the ditches. This paper is intended first to bring forth some problems which should be brought ioto Consideration in designing grassed waterway including hydrologic aspect for determining the drainage requirement, erosion resistance of various grasses and other factors related to the hydraulics of ditch and second to introduce to readers a method of grassed waterway design, though modified, proposed for U. S. Soil Conservation Service practice. The method presented in the paper was primarily based upon the data originated from the experiments of U. S. Soil Conservation Service laboratories and further investigations on the factors involved are hoped to be conducted for applying the design criteria in this country. It is recommended to use the method of grassed waterway design ,presented in this paper from the view point of wide employment of grass lining on ditches which is obtainable at the lower cost and in abundance every where in this country.

The purposes of the study are to measure the relative importance of independent variables, to analyze relation between user satisfaction and use, and to improve the level of user satisfaction in using e-Trade system(uTradeHub). The study develops the independent variables in three dimensions(i.e the quality of system, quality of information, and quality of service), estimates the level of satisfaction on a par with these variables, and analyzes the causal relation of these variables. The major findings of the study are as follows. First, there is a significant casual relationship between the quality of system and user satisfaction, thus the hypothesis is accepted. Second, there is a significant casual relationship between the quality of information and user satisfaction, thus the hypothesis is accepted. Third, there is a significant casual relationship between the quality of service and user satisfaction, thus the hypothesis is accepted. Final, there is a significant casual relationship between the user satisfaction and use, thus the hypothesis is accepted.
