This study observes reporters' awareness on the use of social media and their Core Values by using the Theory of Means-End Chain and drawing conclusions from a Hierarchical Value Map (HVM). In order to analyze reporters' knowledge and awareness on the use of social media via the laddering method, in-depth interviews of 46 reporters were conducted. The study showed that reporters consider sense of kinship, well-balanced understanding, and the desire for knowledge to be important Core Values. The results revealed that the convenience in interpersonal communication, development of intimacy in relationships, entertainment and affection, curiosity, the reduction in the cost of the acquisition of information, understanding of trends in issues, a peek into new information and the maintenance of interests, psychological dependability, and quick updates on information items are considered important Consequences of social media. In the Attributes level, the ability to write postings and links on Facebook and readability and 'follow' and 'mention' features on Twitter were confirmed to be important items in social media. The findings infer that reporters that make use of social media use Twitter and Facebook to build a sense of kinship with other users and gain well-balanced understanding by accessing a lot of information through social media. While this study examined the level of reporters' familiarity with the use of social media via the laddering method, the results cannot be seen as a generalization, as the interviewees were reporters from only the major news organizations.

The purpose of this study is to analyze the factors affecting the influence of the size and composition of the floating population on goodwill and Rent. First, the conceptual difference between location value and rent is clearly distinguished. Second, the value of land price is divided into fixed land value and floating land value. The empirical analysis utilized consulting data from 188 shops in Seocho and Gangnam-gu in 2013 ( restaurants, resting restaurants, drinking places, general stores, entertainment and sports). The results using linear regression analysis are as follows. Goodwill and rent have a positive correlation, but the evaluation system and factors are different. Especially the influence of the floating location factor is larger than the rent. And the fixed location factors such as building deterioration bus stops, were found to be significant influencing factors in the rents, but they did not affect goodwill. This result implies that the value of location of goodwill should be taken into consideration of a temporal and spatial concept. Since, in order to resolve disputes between the landlord and the tenant, it is necessary to accumulate data continuously and to study the objective evaluation system in the future.

Efforts are being made internationally to pay attention to the landscape value of modern and contemporary heritage and to pass it on. However, in Korea, the registration of modern and contemporary landscape heritage as registered cultural properties is insignificant. There has also been little discussion on ways to improve the system in this regard. This study sought ways to improve the registration criteria and classification system of the registered cultural property system so that modern and contemporary landscaping heritage could be protected. Currently, the registration criteria for registered cultural properties are not stipulated for each type of heritage, but are stipulated as a single comprehensive standard. Registration criteria should be separately prepared so that the landscape value of the heritage can be reviewed. First, the registration criteria have an important value in understanding the development of landscape culture. Second, well-preserved landscaping reflects or characterizes the times. Lastly, it should be defined as related to the works of major artists or important figures or historical events. The classification system must match the studied building cultural property classification system, and the detailed types of modern and contemporary landscape heritage should be specified. The major classification follows the building cultural property classification system, but parks and green spaces, squares, and gardens, which can be called a single landscape heritage, should be added to the middle classification. Landscaping heritage, such as gardens combined with building heritage, shall be specified in the subcategory based on building use.

Objective evaluation of the resources of industrial heritage regeneration area is an important prerequisite for design and improvement. The purpose of the study is to comprehensively evaluate the value of the industrial heritage regeneration area. This study identifies the method (model), combining the qualitative factor and quantitative factor. (1) Establish an evaluation system (AHP Hierarchy) based on the resources of regeneration area; (2) Choose an evaluation way based on the type of resource; (3) Calculate the value and total value of various resources in the area. The research is a case study of Canal 5 resort. It expounds the using process of the method and gets the rank and total value of each type of resource in this area, the factors influencing the value (mainly concerned with income), etc. The conclusion is that the value of the reclaimed land should be composed of both the use value and the non-use value; the same factor has different influence on different resources; different factors influence one resource to different extents.

Traditionally, a congestion charge based on first-best congestion pricing theory, namely, the theory of marginal cost pricing theory, is equal to the difference between marginal social cost and marginal private cost. It is charged on each link so as to derive a user equilibrium flow pattern to a system optimal one. Based on this theory this paper investigates on the characteristics of first-best congestion pricing of multiple user class on road with variable demand, and presents two methods for analysis of social and spatial equity. For these purposes, we study on the characteristics of first-best congestion pricing derived from system optimal in time and in monetary unit, and analyze equity from this congestion pricing with an example network.

The Gongchengzuofazeli, which was published in 1734, the 12th year of the Yongzheng (雍正) emperor of the Ching Dynasty, is an authoritative book that discusses the architectural technology and engineering practices at that time. Moreover, buildings constructed during the Ching Dynasty are substantially similar with the book's content. This study is important in that it is done as the first step in conducting a comparative analysis between the Korean and Chinese wood structure mechanism. First, each content of the book is examined according to the editing order. And second, the standard for division between Da-shi (大式) and Xiao-shi (小式) architecture in terms of heavy woodwork method (vol. 1~27) is redefined, from which a new organization is deduced.

This paper analyzed the social cost function of a congestion-prone service system, which is developed from the social cost minimization problem. The analysis focused on the following two issues that have not been explicitly explored in the previous studies: the effect of the heterogeneity of value-of-travel-times among customers on the structure of cost functions; and the structure of the supplier cost function constituting the social cost function. The analysis gave a number of findings that could be summarized as follows. First, the social marginal cost for one unit increase in system output having a certain value-of-travel-time is the sum of the service time cost for that value-of-travel-time and the marginal congestion cost for the average value-of-service-time of all the system outputs. Second, the marginal congestion cost equals the marginal supplier cost of system output under the condition that supplier compensates the customers for the changed service time costs which is incurred by the marginal capacity increase necessary for economically facilitating an additional system output. Third, the compensated marginal cost is the multiple of the marginal capacity cost and the inverse of system utilization ratio, if the service time function is homogeneous of degree zero in its inputs.

Unlike typical corporate investments, IT expenditures have direct impact on many aspects of a business, including those that are difficult to quantify. Therefore, financial indicators alone do not do justice to the full effect of an If investment. Proposed in this paper is a methodology to measure the return on IT investments, including non-financial impacts expressed in terms of monetary values. This methodology shows tangible cost as well as hidden cost by analyzing total cost of ownership. The methodology also produces ROI by performing cost benefit analysis including financial and non-financial factors. This paper suggests a more objective validation of If's impact on the business activities. It rationalizes investment priorities and provides a systematic approach to effective IT investment.
