This paper aims to suggest a validity analysis model that would be helpful for local governments considering u-City construction projects and a methodology for them to promote build-transfer-lease (BTL) u-City projects. This methodology mainly uses quantitative and qualitative analysis based on the Value For Money (VFM) designed by the Public and Private Infrastructure Investment Management Center (PIMAC) under the Korea Development Institute (KDI). BTL projects requires a large amount of capital and involves long-term investments. Therefore, multi-faceted validity analysis is required for the success of a project. This study will enumerate various factors to be considered in the pre-analysis of validity of BTL projects and suggest a methodology to verify them. A case study of a BTL project promoted by Ansan City assisted in designing this study in detail.

Today as the scale of e-commerce constantly expands, the number and the amount of the consumer frauds are also increasing very rapidly, without sufficient levels of systematic support to prevent them. Internet Escrow service is one of the promising payment mechanisms, which guarantees secure electronic trades and payments. Especially, if the real-time product delivery information is available via RFID-based track-and-trace environment, the security and efficiency of the Internet Escrow services would be improved a lot. In this research, proposed a novel approach to integrate EPCglobal Network, which is a de-facto standard for RFID-based information network model, with Internet Escrow services. The proposed service model was implemented in the form of "Integrated Financial Platform", which supports the contracts among trading partners and the payment via Escrow services by being fully integrated with bank systems. Using the implemented EPCglobal Network-based Escrow service system, we would be able not only to shorten the money-flow cycle and to develop new kinds of loan services, but also to overcome the problems of existing Escrow services including the lack of product-related information and the delay of purchasing decisions.

Controversies over NEIS(Network of Education Information System) began with very deep concern about infringement of human rights stemming from NEIS. A large information system which accumulates and uses huge size of individual information is always able to deeply infringe on human rights. But the ministry of education would not do the best not to be 'Big Brother' being dazzled by instrumental efficiency of information technology. NEIS has demonstrated problems of the information policy of Korea strongly driven in the name of 'E-goverment'. It has very strong characteristic of the statist economic growth policy focusing on more economic possibility than other. In this situation, making money is easily considered more important than protecting human rights. Information capitalism is nurtured at the sacrifice of human rights. So, we have to face problems of 'E-goverment' in order to correct the NEIS problem, The most important task to correct the NEIS problem is to make an element law protecting privacy and to establish an independent national institute protecting privacy

Carrier billing services market is growing according to the technical development. This study investigated the limiting factor in carrier billing services and suggested the improvement factor for it using the Delphi Method. The amount money to use in carrier billing charges should be provided in their credit based and the accumulated payment using a text message is displayed and also telecommunications carriers and carrier billing firms are the least responsible for consumer harm. It also provides administrative responsibility for communications carriers and billing services company for non recognition and payment. The service provider to prove negligence not proven by consumer and telecommunications billing service delinquency rate is applied at a rate such as a credit card and it also should integrate retail payment and service fee. This study will contribute to the communication billing services market growth through improved communication billing service. Further research is needed to continue the study of the factors that emerged from communication and billing services due to emerging technologies and services.

To distinguish cancer cells from normal cells, H&E (Hematoxylin & Eosin) staining is required. Pathological staining requires a lot of money and time. Recently, a digital dyeing method has been introduced to reduce such cost and time. In this paper, we propose a novel digital pathology algorithms. The first algorithm is the Pair method. This method learns the dyed phase image and unstained amplitude image taken by FPM (Fourier Ptychographic Microscopy) and converts it into a dyed amplitude image. The second algorithm is the unpair method. This method use the stained and unstained fluorescence microscopic images for modeling. In this study, digital staining was performed using a generative adversarial network (GAN). From the experimental results, we noticed that both the pair and unpair algorithms shows the excellent performance.

This study aims to provide guidelines on future policy for restructuring the scheme of aid programs associated with If small and medium-sized enterprises (i.e. SME) in Korea. For this purpose, we investigate an empirical dataset of recent aid programs deployed by Ministry of Information and Communication (i.e. MIC) for the last four years First, it is examined that the programs are practiced in accordance with their own policy objective by comparing matching samples between two groups such as program beneficiary and non-beneficiary companies. Second, positioning transition of programs within a same category is visualized in terms of two business portfolio analysis matrices. Third, an affiliation network matrix of (he programs is newly developed and then we attempt to analyze the programs relationship by the application of multidimensional scaling method to the affiliation network matrix. The empirical dataset is composed of two different kinds of corporate datasets. One is a corporate dataset of 8,994 beneficiary companies that are aided by MIC during the year of '03-'06. The other is also a corporate dataset of 18,354 non-beneficiary companies that have no records of the program supports during the years at all. Particularly, the matching samples of non-beneficiary companies are prepared in order to have comparable corporate age years (i.e. CAY) against beneficiary companies' CAY. Results show that; 1) up-to-date, the programs are properly assigned to IT SME conforming to their own policy objective; 2) however, as the year goes on, the following two distinct positioning transitions are revealed such as (1) both CAY and corporate sales (i.e. SAL) are increased simultaneously, (2) ratio of intangible assets (i.e. RIA) is decreased and ratio of operating gain to revenue (i.e. ROR) is increased. Hence, the role of the programs gets weakened with regard to providing seed money to technology innovation-typed IT SME so that a managerial adjustment of the programs is required consequently; 3) even though the model adequacy is not satisfactory through the analysis of multidimensional scaling method, the relationship of indirect-typed programs can relatively be stronger than that of direct-typed programs.

Rural communities have been isolated from social and economic changes underway in the broader society. Trends towed an urbanized society have depopulated many rural areas (Flora, et al, 1992). The South Korean government has targeted efforts toward an urban centered economic development policy, which has neglected the rural areas. The South Korean government also has indoctrinated rural community development with a quick-fix approach. Self-directed economic organizations based in rural South Korea began to emerge in the late 1980s. Since the 1980s, South Korean agricultural sectors have been overshadowed by globalism. McMichael (1996) stated that rural communities have two options. A immunity should either End its niche (i.e. the commodities or products that can have advantages in the international trade market) or protest against globalism to survive if rural communities fail to find a niche under globalism. South Korean neat communities did not have enough natural resources nor enough money to invest for their rural community economic development programs. These limitations made it difficult for South Korean coral communities to compete in a global economic environment. Israel, Coleman, and Ilvento (1993) stated that local leadership is a critical component in the ability of communities to respond to lang-standing problems and emerging needs. Swinth and Alexander (1990) asserted that rural leaders are critical actors in rural community development. Whether rural communities succeed in finding their niche or not, the role of rural community leaders is important for rural communities to find ways to cope in the international agriculture market.

This study identified the types of motives for reading consumer reviews of apparel products for online stores and classified shoppers into the groups based on motives. Data were collected from eleven Korean women by a focus group interview and from 313 females by an online survey. Respondents were in their 20s' and 30s' with significant experience reading consumer reviews of apparel products for online stores. The seven motives found by interviews were reduced to four types of motives by factor analysis: Right product choice and judgment of product value, risk reduction, saving time and money, and fun/killing time. The motive for the right product choice and judgment of product value was the highest and the motive for fun/killing time was the lowest. Consumers were classified into four groups based on motives: Utilitarian shoppers (25.8%), shopping-task oriented shoppers (36.8%), multiple-motive shoppers (19.7%), and moderate-motive shoppers (17.7%). There were significant differences among age groups and the amount of reading reviews posted on a product and the duration of reading reviews for online stores. In addition, managerial implications were developed.

The religious organization members have a unique take on the spiritual factors related to their daily life. The present study contributed to the lack of discussion investigating this particular pool of data's financial behavior. This article regressed several predictors of economic behavior, i.e., the locus of control, financial attitude, income, and religiosity, with 460 respondents. The results of the research are as follows: Financial attitude partially influences the financial behavior of Muhammadiyah committee members. Income partially influences the financial behavior of Muhammadiyah committee members. This research indicates that income is one of the factors that plays an essential role in determining the merits of improvement of the financial behavior of Muhammadiyah committee members. The higher the level of income received by Muhammadiyah members, the higher the desire to spend the money. Religiosity partially influences the financial behavior of the religious board of Muhammadiyah members in Indonesia. The higher the religiosity of Muhammadiyah committee members will encourage better financial management. Religiosity indicates how often individuals or Muhammadiyah members practice the religious sharia that they embrace. The findings of this study reveal that locus of control, financial attitude, income, and religiosity are the strong predictors of the board of the religious organization's financial behavior in Indonesia.
