The DO1 is an opaque string or dumb number - nothing at all can inferred from the number. However some identifies can include some intelligence in the number itself, which will tell the user subject and meaningful information about the entity that is being identified. Therefore whether the DO1 suffix should be 'dumb' or 'meaningful' is a major issue in DO1 syntax structuring. Although the choice of DO1 Suffix is entirely optional, many DO1 registrants have been used existing IS0 standards such as SICI, ISBN, ISMN, etc. for identification of information resources. It is also important to consider that intelligence in a system of identifiers may be carried out by means of the DO1 structure. It was suggested that there should be an explicit part of the DO1 syntax which declares the meaningful information of the digital objects.

The contingent valuation method used survey questions to elicit people's preferences for public goods by finding out what they would be willing to pay for specified improvement in them. The method is thus aimed at eliciting their willingness to pay in money amounts. It circumvents the absence of markets for public goods by presenting consumers with hypothetical markets in which they have the opportunities to buy the good in question. The hypothetical markets may be modeled after either a private goods market or a political market. Respondents are presented with material, often in the course of a personal interview conducted face to face. An on-site survey was conducted to 1107 randomly selected P-mountain users using a dichotomous choice questionnaire for the contingent valuation method. Seventeen different bid sets were chosen ranging from the lowest bid of 300won to the highest bid of 2,100won to elicit a reasonable entrance fee in the suggested bid had been determined, and the expected value of willingness to pay was estimated using binary-logit model. The average public value of P-mountain per individual user was estimated to be 1,055.92won∼1,995.61won according to the binary-logit model. The economic value of this P-mountain which includes both use value and existence value can be determined by aggregating the average value giving total willingness to pay for the entire population, in this case 5.491 billion ∼ 10.377 billion.

The purpose of this study is to identify the usability of parents of developmental rehabilitation services for disabled children. To that end, 120 disabled children and 120 parents were surveyed in 17 cities, including nine cities in Gangwon Province, welfare centers and private institutions in the military. Data analysis used SPSS Statistics 18 and the main findings are as follows. First, there was a significant difference in the type of supply and demand in the general characteristics of parents using the developmental rehabilitation service. Second, the service use characteristics of the developmental rehabilitation service showed a statistically significant difference in the service satisfaction of the private care institution, and third, the process and effect of the service provision of the developmental rehabilitation service were shown to be significant in the service satisfaction level. Fourth, the effect of choice on service satisfaction was significantly shown in the accessibility of developmental rehabilitation services. The significance of the research results is to confirm that the service provision and access to the services of developmental rehabilitation services increases the satisfaction level of disabled children's parents. Accordingly, the discussion and implications for improving the satisfaction level of the use of parents using the developmental rehabilitation service were presented.

This study aims to discuss what is needed for meaningful development of social service, focusing on Community Service Investment Project(CSIP). The contents of CSIP were analyzed on applying the Analytic Framework by N. Gilbert and H. Specht and the values that were the basis of social choice. Based on the analysis of output and policy value of this Project, this study draws three social service policy issues. First, 'localization' is needed to be emphasized more in CSIP because there are few programs that take into account the regional peculiarities. Second, as the social services focused on the individuality of the citizen is more important, it is necessary to examine 'sustainability' of CSIP. Third, in relation to the community building, it is necessary to discuss the modification of the CSIP's goals. As process for improving community, it is needed to review for local residents not participating in decision-making process, income-based user selection and appropriateness of the term 'investment' in the project name.

The evolution of information technology and proliferation of hospital management and managerial applications of computing has led to change in the characteristics, uses and evaluations of software for the hospital management. With the growing proliferation of microcomputer use and the value-added for management strategies, more and more software has been massively developed, produced and distributed for the hospital industry. The user is faced with an increasingly difficult choice in the evaluation and selection of software. For many reasons, users frequently must rely on expert evaluations of the technical functions and quality of software. The objectives of this study are to provide selection criteria for an Electronic Medical Record (EMR) and to develop an evaluation framework for the Hospital Information Systems. The major findings of our study are as follows (1) the identification of EMR evaluation characteristics (2) the design and development of EMR selection model and (3) the evaluation of the importance for EMR characteristics using Analytic Hierarchy Process (AHP). We identify 6 characteristics and 22 sub-characteristics of the EMR, calculate their weights, and decide the best configuration. Especially, the AHP methodology can be applied to gather knowledge from multiple experts. Because AHP can 1) facilitate the participation of multiple experts 2) increase group productivity and therefore result in both quantitatively and qualitatively superior outcomes than that of a single individual's work 3) provide a mechanism for reconciling conflict from multiple expert 4) validate the acquired knowledge, providing consistency of facts, and 5) enhance the accuracy reliability of the acquired knowledge increase through of the reliability provided by consensus across multiple experts. Although some further research is required, the proposed model can be regarded as a basis for the selection of EMR.

Youtube has become so popular that it is called the age of YouTube. As the number of users and contents increase, the choice of information increases. However, it is difficult to select information that meets the needs of users. YouTube provides recommendations based on their watch list. Therefore, in this study, we want to analyze the channel of user's subject in various angles and provide the proposed scheme based on the crawled channels, measurement of the perception of channels and channel videos through quantitative data and hidden qualitative data analysis. Based on the above two data analysis, it is possible to know the recognition of the channel and the recognition of the channel video, thereby providing a ranking of the channels that deal with the topic. Finally, as a case study, we recommend English learning channels to users based on numerical data statistics and emotional analysis results to maximize flipped learning effect regardless of time and space.

As the urbanization progresses, the demand for parking in large cities surges compared with that for parking lots. However, the space for securing a parking lot in a large city is physically limited and a budget problem also arises. Therefore, a shared parking system that can utilize existing parking lots is becoming important. This study was carried out to analyze the parking area efficiently for the residents parking area. As a result of the questionnaire survey, it was the most frequent passage to work / commuting and business purposes. The most important factors in parking were 'Parking charge', 'Walking distance to the destination after parking', 'Parking lot searching time' Approximately 46 % of the respondents were female. As a result of the quantitative analysis of the factors influencing the potential use of the intention to use as a dependent variable, it was analyzed that the policy was effective to reduce the parking fee to less than 500 won per 10 minutes and take about 3-6 minutes to search.

Real-time traffic information disseminated through VMS is known to have effects not only on driver to plan a route choice, detour the congestion, and cope with incident, but also on VMS operator to manage the traffic volume indirectly. But, the dissemination of traffic information is operated in the side of provider, not of user. Importance-Performance analysis (IPA) offers a simple, useful method for simultaneously considering both the importance and performance dimensions when evaluating or improving strategy. This technique has been successfully used in a variety of settings to define priorities and guide resource optimization decisions. This study uses IPA to evaluate traffic information strategies through VMS to make resource improvement recommendations. It gained 760 samples by field surveys, which are conducted in Korean Thanksgiving Day, weekday and weekend at the service areas of expressways. The results indicate that the motivations in quadrant I (concentrate here) are dissemination of exactly information and quick transmission, while distance of VMS, most drivers are not satisfied with that is located in quadrant III (low priority).
