The G2B system is one of the important information systems in the e-government implementation. It is difficult to measure the cost reduction effect of the system introduction because there are many participants in the complex procurement processes. Previous approaches of the performance evaluation of such processes have been based on conducting some surveys and interviews with statistical methods. Therefore there have been some limitations in the verification of feasibility. Therefore this study tries to suggest a case of performance evaluation about the cost reduction in using of the G2B system by analyzing operational DB data from the G2B system. This study analyzed the procurement processes of G2B system according to 'goods' and 'facilities/services' and classified the procurement processes into 12 sub-processes. By developing an evaluation model for the cost reduction of e-procurement, we derived the whole cost reduction effect was 8,000 billon Won for the use of Korea KONEPS G2B system in 2008. Specially the cost reduction in the private sector was 6,600 billion Won. It was mainly due to the decrease of the offline visits to the related organizations to participate a bidding process. Moreover, the cost reduction of using shopping mall was 1,000 billion Won among the total 1,400 billion Won in the whole public sector. The main contribution of this paper is to show the more objective evaluation result of the use of e-procurement, which verifies the necessity of G2B system.

As the particulate matter (PM) is fatal for human being, the government authorities try to lessen PM with a variety of policy instruments. To increase the efficiency of the policy, we need to understand people's perception and risk avoidance on PM. Thus, the research explored what attribution styles, involvement, and perceived health status have an influence on preventive intention. First, we found three attribution styles on PM occurrence through factor analysis: daily life(DL), domestic industry & environment(DI&E), and Chinese industry & environment(CI&E). We also found that involvement(${\beta}=.465$, p<.001), CI&E(${\beta}=.222$, p<.001), DL(${\beta}=.173$, p<.01), and DI&E(${\beta}=.143$, p<.05) have an influence on preventive intention in order. Finally we discussed suggestions for future study.

Blockchain technology prevents tampering of central authorities that manage voting process, enhancing trust in the vote results. This technology enables citizens to participate more directly in the areas where delegation was inevitable due to the difficulties in polling fair and trustworthy public opinions. There are many projects around the world proposing to implement voting system for public decision making using blockchain technology. The blockchain voting system is expected to work as a transparent and fair channel for polling public opinions, which will transform the public decision-making process and governance. Korean National Pension Service (NPS) recently introduced stewardship code to better represent the interest of beneficiaries. However, because of the mistrust in governance of NPS, introduction of stewardship code is facing criticism for potential misuse of their voting rights against the interest of beneficiaries and for government's interference with corporate management. This study proposes a voting system applying blockchain technology for polling the opinions of National Pension Fund's beneficiaries to support public decision-making, and discusses social and institutional conditions for implementation of the proposed system.

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

This study aims to explore the characteristics of platform for social service delivery and the electronic voucher system as an instrument for the delivery. The paper discusses the concept and characteristics of platform and reviews the factors by which firms migrate to platform. Social service e-vouchers are an example of a government platform that pays e-vouchers to consumers and gives them the choice of services. Then it analyzes the case of platform establishment to deliver social services. The demand on welfare services has changed with demographic structure. The change in demand requires innovation in the social service delivery system and adoption of strategies to move to the platform. Factors that enabled the social service delivery platform to build both demand and supply sides include access to employment policies, industrial connection, workforce training, and requirements for social service eligibilities.

The digital archives of E-culture, E-government, E-learning, and E-business have grown by leaps and bounds worldwide during the last several years. While we have invested significant time and effort to create and maintain those archives, we do not have the ability to make digital records generated by the processes all available across generations of information technology, making it accessible with future technology and enabling people to determine whether it is authentic and reliable. This is a very serious problem for which no solutions have been devised yet. This paper discusses practical technologies for digital archives and preservation to succeed, and describes a general framework of the life cycle of information to address this important problem so that we may find reasonable ways to preserve digital records that can be analyzed and evaluated in quantitative measures and incremental manners.

Water, energy, and food security already became a risk that threatens people around the world. Increasing of resources demand, rapid urbanization, decreasing of natural resources and climate change are four major problems inducing resources' scarcity. Indeed, water, energy, and food are interconnected each other thus cannot be analyzed separately. That is, for simple example, energy needs water as source for hydropower plant, water needs energy for distribution, and food needs water and energy for production, which is defined as W-E-F nexus. Due to their complicated linkage, it needs a computer model to simulate and analyze the nexus. Development of a computer simulation model using system dynamics approach makes this linkage possible to be visualized and quantified. System dynamics can be defined as an approach to learn the feedback connections of all elements in a complex system, which mean, every element's interaction is simulated simultaneously. Present W-E-F nexus models do not calculate and simulate the element's interaction simultaneously. Existing models only calculate the amount of water and energy resources that needed to provide food, water, or energy without any interaction from the product to resources. The new proposed model tries to cope these lacks by adding the interactions, climate change effect, and government policy to optimize the best options to maintain the resources sustainability. On this first phase of development, the model is developed only to learn and analyze the interaction between elements based on scenario of fulfilling the increasing of resources demand, due to population growth. The model is developed using the Vensim, well-known system dynamics model software. The results are amount of total water, energy, and food demand and production for a certain time period and it is evaluated to determine the sustainability of resources.

In order to investigate the species, serobiological characteristics and antibiotic sensitivity of Pseudomonas spp, we isolated Pseudomonas spp from 57 spring waters around Seoul area for spring, summer and autumn and identified Pseudomonas spp by biochemical characteristics and serological method. And also we tested the antibiotic sensitivity test by discdiffusion method. Of 57 spring waters tested, Pseudomonas spp were isolated from 33 spring waters(57.9%). Isolation rate of Pseudomonas spp in spring season was 28.1%, summer 21.1% and autumn 28.1%. Only 1 spring water was detected Pseudomonas spp in all seasons and 9 (15.8%) were detected for 2 seasons and 13 (22.8%) were for only 1 season. Isolation rate of Pseudomonas spp at Mt. Cheonggye was 50% and followed by Mt. Bookhan 35.7%, Mt. Daemo 33.3%, Mt. Dobong 29.6%, Mt. Surak 25.9%, Mt. Woomyun 22.2% and Mt. Bulam 7.4%. Of 44 Pseudomonas spp, 22 strains (50%) were identified by Ps. putida, Ps. aeruginosa, Ps. fluorescens and Ps. mendocina were identified 6 strains (13.6%), respectively. 4 strains (9.1%) were identified by Ps. aureofaciens. Of 6 Ps. aeruginosa, serotype A was 2 strains, B, E, G, and K was 1 strain, respectively. Of 44 Pseudomonas spp, resistance rate to amoxicillin was 90.9% and followed by chloramphenicol 84.1%, tetracycline 84.1%, carbenicillin 81.8%, nalidixic acid 68.2%, neomycin 38.6%, streptomycin 31.8%, gentamicin 4.6%, kanamycin 4.6% and colistin 2.3%. Ps. aeruginosa was more sensitive to carbenicillin than other Pseudomonas spp isolated from spring waters in Seoul area but more resistant to kanamycin, and Ps. aureofaciens was no resistant to streptomycin. Among multiple drug resistance, resistance to 5 drugs was 31.8%, 4 drugs 15.9%, 7 drugs 13.6%, 1 drug and 2 drugs 4.6%, and 8 drugs 2.3%, respectively. The multiple resistance patterns detected highestly were NA-CB-C-TE-AMC (18.2%), NA-CB-N-C-TE-AMC (13.6%), CBC-TE-AMC (11.4%) and NA-CB-N-C-TE-AMC-S (9.1%).
