Recently smart phones have been proliferating widely and quickly. Since the number of mobile apps that are being developed and deployed to domestic/international app stores is rising, more apps are being installed and deleted by users without any difficulty. The deployed apps are each attested through distinct verification framework of specific app stores. However, such verification frameworks are insufficient in checking security concerns. Unfortunately, the security verification framework is necessary since the incidents of leaking privacy and confidential information are being increased in lately. The aim of this paper is to provide the security verification framework that assures security and reliability of the e-government mobile apps. In order to verify proposed verification framework, a few apps were selected and inspected through proposed framework and these inspection results are included in this paper.

As a leading nation of ubiquitous technology, South Korea has been promoting u-City pilot projects throughout the country. According to 'Fundamental Construction Law of u-City,' u-City projects are classified into old-town and new-town types. However, most projects have focused only on the new-town type. Pushing forward large-scale land development projects, Korea Land and Housing Corporation (LH Co.) under Ministry of Land Transport and Maritime Affairs (MLTM) has gained a development profit out of the u-City infrastructure and then donated the infrastructure to a local government without making any plan for operations. In the process of u-City pilot projects, old-towns have been relatively ignored and various of unexpected problems have emerged. Building the u-City of an old-town is not easy due to many constraints such as huge initial investment, long validity and verification procedures, lack of useful services for citizens, lack of professional outsourcing methods for business promotion, high operating costs of the integrated control center, inadequate law related, insufficient institutional requirements and so on. This paper introduces a case study on u-City development for an old-town, Ansan City, as a private investment project. The case will help boost u-City projects for old-towns by solving their problems and providing an effective operational mechanism. As the first BTL (Build-Transfer-Lease) project for constructing u-City, 'Broadband Information Network Development Project' of Ansan City will provide a reference model of expanding u-City projects for other cities.

This study was performed to assess the nutritional status of low income elderly women aged ${\geq}$65 years residing in Gyeongnam Masan (n=124). Nutrition intakes, food intake frequency, and health-related behaviors including smoking, drinking, and exercise were investigated. Nutrition intake was calculated by the 24-hour recall method using CAN-pro (ver. 3.0). Average daily intakes of energy were $1,142.3{\pm}39$ kcal (71.4% of EER) in subjects aged 65~74 years and $1,071.0{\pm}41.7$ kcal (66.9% of EER) in subjects aged ${\geq}$75 years and the subjects consumed energy less than both 75% of estimated energy requirement (EER). The proportions of energy derived from protein, fat, and carbohydrate were 15.4:15.5:70.6 (aged 65~74 years), and 15.3:13.4:70.8 (aged ${\geq}$75). Nutrients consumed at less than estimated average requirements (EARs) were Ca (60.4%), P (98.4%), Zn (91%), vitamin E (48% of adequate intake, AI), vitamin $B_1$ (63.3%), vitamin $B_2$ (54%), niacin (87.7%), vitamin C (62.5%), and folate (50.5%). Especially, the intakes of Ca (58%), vitamin E (41% of AI), vitamin $B_1$ (60%), vitamin $B_2$ (50%), folate (46.5%), and vitamin C (54%) were 75% less than the EAR for people aged ${\geq}$75 years. According to the food intake frequency survey, the intakes of calcium, milk, fruits, and vegetables were very poor. In conclusion, this study suggests that a nutritional support program for elderly women of low socioeconomic class must be provided by the government to improve the quality of remaining life.

Ubiquitous City is emerging as a new paradigm in future city development. U-City is nationwide project for future strategy to implement sustainable city environment and solve several issues in urban area. And as worldwide leading role on future city research, there are lots of U-City related researches in Government and Industry sector. However, it has raised unsustainable development concerns that indiscriminate promotion and visibility for long-term effects because it is not conducted an assessment. Thus, to overcome these problems and in order to develop a more stable U-City project, need to a fundamental consideration about U-City evaluation. This study is to provide the evaluation framework for Ubiquitous City(U-City). The framework is consisted of evaluation dimensions derived from characteristics of U-City development project. From this research, we expect it helps U-City development to be inspected and managed.

Many studies have been published on the relationship between project management styles and project performance. In recent researches, it is argued that project management styles should be different based on project characteristics and these project characteristics may have an effect on the relationship between project management styles and project performance. However, there are few empirical studies covering these issues. In this study, we examined the effect of project characteristics (i.e., degree of newness) on the relationship between project management styles (i.e., team autonomy, internal and external communication, individualism orientation) and project performance. The empirical results using 78 government sponsored R&D projects showed that team autonomy has a stronger positive effect on project performance as project newness becomes higher. In addition, as project newness becomes higher, internal communication showed a stronger positive effect on project performance, while external communication had a stronger negative effect.

The maintenance prices in information security industry between Korean companies and foreign companies have been a big difference. Korea Information Security SW maintenance standards were not adequate for the rate, and there was disagreement between domestic companies and governments. This research, therefore, surveyed a standard of information SW and the status of maintenance payment rates. The study suggests an estimation method and verifies the method and an appropriate maintenance cost rate. According to the results of the study, the current maintenance cost should be increased or decreased independent with a kind of information security systems. Based on the study, Korea government is able to change the maintenance policy in information security. And the domestic companies get a theoretical ground for improving the rates of maintenance costs in information security systems and are able to allot the resources effectively.

The third party logistics(3PL) is generally understood as the logistics activities providing a comprehensive logistics services, all or partly outsourced by the customers on a larger term contract basis, ranging from making logistics strategies to implementing information technology services. A lot of companies in advanced countries such as the U.S.A. or some of the European countries have actively outsourced to logistics service providers in efforts to increase the efficiencies in logistics operation rather than doing themselves. In light of these environments, outsourcing to third parties has become a strategic issue demanding greater attention in corporate boardrooms. First, after deciding their logistics outsourcing, the companies have to set up their aims of 3PL through the development of logistical strategies. Second, the companies must decide service provider that fits to their business environment and conditions. As it is reported that 3PL services will bring a high rate of return and its potential will be more signigicant, providers and users of 3PL services and government ministry should prepare the way of improvement of logistics institution and plan to activate 3PL services to reach the advanced foreign countries level.

This Study is aimed at optimal sequencing of water supply projects for water demand from the application in water resources field of dynamic programming because a minimum present cost strategy for investment in water supply projects plays an important part of installation of some projects. In analysis, the relationships of the future water demand and numerous possible independent projects that are expected to meet water requirements up to some future data in Daegu city were used and future water demand were estimated from the exponential function method, the method used by the Water Works Bureau of Daegu City government which is a kind of geometric progression method and the mean value of these two methods. The results showed that the optimal sequencing of water supply projects using Dynamic Programming was reasonable and the changing of the estimation method of future water demand made a difference among optimal sequence of projects while the changing of annual rate of interest had influenced on present value cost only. In general, the best sequence for constructing the seven projects was the order of D-E-G-F-C-B-A, with the corresponding period for 33-38 years.
