IoT (Internet of Things) is a collective term referring to application services that provide information through sensors/devices connected to the internet. The real world application of IoT is expanding fast along with growing number of sensors/devices. However, since IoT application relies on vertical combination of sensors/devices networks, information sharing within IoT services remains unresolved challenge. Consequently, IoT sensors/devices demand high construction and maintenance costs, rendering the creation of new IoT services potentially expensive. One solution is to launch an IoT open market for information sharing similar to that of App Store for smart-phones. Doing so will efficiently allow novel IoT services to emerge across various industries, because developers can purchase licenses to access IoT resources directly via an open market. Sharing IoT resource information through an open market will create an echo-system conducive for easy utilization of resources and communication between IoT service providers, resource owners, and developers. This paper proposes the new business model of IoT open market for information sharing, and the requirements for ensuring security and standardization of open markets.

As smart phones have become widely adopted, they have brought about changes in individual lifestyles, as well as significant changes in the industry. As the mobile technology of smart phones has become associated with all areas of industry, it is not only accelerating innovation in other industries such as shopping, healthcare service, education, and finance, but is also creating new markets and business opportunities. The preparation of thorough security measures for smart phones is increasing in demand. While offering excellent mobility and convenience, smart phones can be exposed to a range of violation threats. In particular, it is necessary to make efforts to develop a security system that can preemptively cope with potential security threats in the banking service area, which requires a high level of reliability. This paper suggests a security reference model that is considered for the smart phone-based joint mobile banking development project being undertaken by the Bank of Korea in 2010. The purpose of this study is to make a security reference model for a reliable smart phone-based mobile financial service, by recognizing the specific security threats directed toward smart phones, and providing countermeasures to these security threats. The proposed mobile banking security reference model is useful in improving system security by systematically analyzing information security threats to the mobile financial service, and by presenting the guideline for the preparation of countermeasures.

Since the middle of 1990's, domestic apartment building suppliers have set up brand images to overcome the difficulties in financial situation after IMF foreign exchange crisis. The main trends in recent apartment buildings could be classified generally into several types, such as 'Ubiquitous Intelligent(standing for High-tech)', 'Walkable Community(community-friendly)', 'Eco-friendly', 'Ergonomic Humanity(Human Engineering)', 'e-easy Home through Internet(Digital Home)'. With those brand images, construction enterprises have been making inroads into local apartment markets, especially one of the region around Dae-gu. It is meaningful and worth researching and analyzing the local residents' preferences and tendencies to form marketing strategies of brand images. Here, this research and analysis is of pre-examination before getting down the study of this subject.

Recently, with the improvement of national income, the increase of int e rest in the consumers, health, and the enhancement of recognition of environment the demands of environmental-friendly agricultural products(EFAPs) are on the rise rapidly. The demand in the market for EFAPs increases rapidly, and the sales amount increases by 30~40% every year. But, it is in situation that the EFAPs arc not distributed well between the producers and consumers now. That is, the producers of EFAPs can not End th e ir markets. And, the consumers do not trust the EFAPs. Also, it is in situation that it is difficult to promote the demand because of relatively higher prices than the general agricultural products. To solve these problems, it may be summed up as follows. First, it needs to reduce the distribution cost by the construction of stable supply basis. Second, it needs to improve the distribution system of EFAPs. Third, it needs to enhance the differentiation and improve the consumers, reliability. Fourth, it needs to make in brand and extend the various publicities. Fifth, it needs to construct the supporting system and enhance the cooperation with the related institutions. Sixth, it needs to End new demand and introduce the procurement system by the government.

The objective of the study is to propose to the strategy to make korean main ports to international logistics center in Northeast Asia. so this study's construction is constructed four steps. First, analysis the environment of economy, business and logistics industry in Northeast Asia. Second, analysis the constructions and characters of Free Zone Act. Third, analysis of Korean Government's policy about Free Zone. Forth, propose the growing strategy of Free Zone. In 1999 Northeast Asia was adopted in Korea, which will facilitate the process and strengthen the international logistics capability as a international logistics hub in Northeast Asia. But only adoption in the point of law is not enough to growing korean main seaport and airport to a international logistics hub. so various strategies are needed. In this study, we propose the growing strategies that are to establish and manage the free zone of ports and its hinterland are: the establishment of a long-term vision of international logistics complexes, the improvement of the proximity to markets/customers by way of linkage of global networks, the activation of the industrial complex in hinterland, the development of the skilled labor and the labor climate, the cooperation between governmental bodies and government/provincial bodies, continuous development of logistics infrastructure and so on.

In this study 61private brand skirts and 67 brand name skirts were compared to see if the skirts from the different markets were suitable for both comfort and movement. The researcher chose size 66 skirts with a waist circumference of 68~70cm and hip circumference of 92cm. The resets are as follows. (1) In the waist measurement, the minor brand skirts were made at the maximum measurement (70cm) and the department store brand skirts were at the minimum (68cm). (2) Compared with the standard back split length of 9cm for a 48cm-long skirt, the minor brand skirts had a split of only 4.5cm, while the department store brand skirts were 3cm less (split length-6cm). From this result, we see that both of them are less practical than they are supposed to be (3) For the department store skirts, the hip circumference and waist circumference show a significant correlation to skirt length (p<0.05) and back split length (p<0.001). Larger waist & hip measurements equal longer split length. For the minor brand skirts, the length of the split shows a significant correlation to the depth of the hem-line Shorter split equals smaller hem depth. From these results, it can be concluded that the two groups of skirts do not differ except for back split length and waist circumference, but regarding the split length, both of them should be modified for else of movement and comfort.

In this paper, I scrutinize what Korea has achieved from the KTX(Korea Train Express) project for the past one year of operation since it was open to public in April 2004 while looking into some improvement measures for better services in the future. I tried to compare the clements with those of the Tokaido Shinkasen in Japan. As things may turn at its premier operation, the KTX has been suffering from a small number of passengers, low in demand. However, when I compared the previous year with the post KTX operation of one year, demand of the passenger has increased $40\%$ on Kyong-bu line. I figured the first one year of the KTX operation pretty much followed in the footstep of the Tokaido Shinkansen's. For example, the rate of the each train to be on time as the timetable was equivalent while KTX went through less technical problems than the Tokaido Shinkansen. I have come up with some ideas for improvement, which I believe will lead to the development growth of KTX. First, I suggest that we complete the construction of laying new rails on Kyong-bu line at the earliest possible time. Second, we need to extend the high speed network as well as the rail modernization. Last, I have no doubt that we should secure high technology before we forge in the overseas markets.

This thesis analyzed the uniqueness of a toilet plane structure, centering on a case of Beautiful Public Toilet Construction Project under a project by Chungcheongnam-do and drew a conclusion as followings. Most of public toilets, constructed under a project by Chungcheongnam-do, were located in remains, tourist resorts, parks, and the outskirts of traditional markets. They were constructed at the selected location within an easy access of most user and plane structure was also designed so that the persons, in charge of management and maintenance, and the users could use them without difficulty. But some public toilets didn't establish the handicaps' toilet or made them difficult to sue due to location or size. The plane structure style was various such as a rectangular, stream line, or circle in accordance with location or building size. A circle-styled toilet offered a good view but didn't offer a good access or an effective space for users. In addition, when a handicapped person enters a toilet, he or she has to enter or go out of it through a sliding dor. So a constructor has to make progress of a work in accordance with this point.
