North Korea has stressed Information Technology in policy fostering science as Kim Jong-il has been interested in IT industry. In view of development of e-business in Northeast Asia, South Korea is to cooperate with North Korea. It is the time to look into the current situation, strategy and issues of IT in North Korea. Although North Korea is forced to select the development of IT Industry as growth engine, the problems in the IT Infrastructure are as follows:lack in communication infrastructure, lack in diversity of software, low level of hardware, limited use of internet. This paper deals with the IT Infrastructure of North Korea and IT and e-Commerce Cooperation, introduction of e-Trade between South and North Korea.

The purpose of this study is to find out current problems facing the commodity trust of e-marketplace and export channel and product adaptation strategy in e-trade. This study will be an important benchmark to shed the light on understanding export channel and the localization adaptation strategy. The business performance of export corporations in Korea so that they will be able to build their own winning marketing adaptation strategy. This study will also obviously provide Korean export corporations having invested in foreign countries with the solid base to set up their marketing channel and localization adaptation strategy to compete with other export corporations abroad.

The fact that Pyeongtaek Port is located ideally at the central point of the Yellow Sea's Economic Zone and it is very close to the metropolitan area of South Korea which occupies more than 50 percent of the total trade volume in terms of tonnage is providing a good prospect of development for the Port of Pyeongtaek. This study examines the perception of shippers in Kyonggi-do on the development of Pyeongtaek Port, giving some suggestions to the Pyeongtaek Port Authority. It begins with a description of the port such as current economic status, statistics on the economy, trade and investment regarding the Port of Pyeongtaek. According to a particular questionnaire survey conducted in December 2001, the major obstacles to the utilization of the port are as follows: a shortage of liner shipping routes, lack of container handling facilities including container terminal, crane etc., and port sales promotion activity. Therefore the port should make aggressive efforts to attract container cargoes to and from China by expanding port facilities, implementing effective marketing strategies, introducing a customs-free zone/free trade zone, and strengthening port sales etc.

This study examines the policy direction and specific countermeasures for addressing possible port labour issues from the perspective of Just Transition which may be raised by closing coal fired power plants in Korea. Current energy transition policy and port labour policy in Korea are reviewed and case studies in the countries which has experienced closure of coal fired power plants are undertaken. Although it varies from country to country, a similar approach was found that the employment problem of coal fired power plant closures and measures based on Just Transition regime to mitigate the negative impacts that occur in the region are the key to successful transition. It is suggested that countermeasures for port labour should be institutionalized for providing stakeholders with legal stability covering labours not only directly employed by the plants but also employed in entities in the whole supply chains.

The objective of this paper is to investigate digital transformation in logistics within the shipping and logistics industry. This paper examines the case of Hyundai Merchant Marine (HMM) and draws insights from its success in becoming the top company amidst the industry challenges. To achieve a more in-depth analysis, a single-case study approach was employed. Various secondary data have been analyzed to support the examination of HMM's digital transformation. HMM has emerged as a global leader in transportation services. The company's success is attributed to its development of diverse ships, robust logistics systems, and pioneering a digital logistics platform, ultimately overcoming the crisis. Especially, this paper show that the digitalization of logistics has been analyzed as the most significant transformation. The findings of this paper can offer valuable implications for other companies grappling with similar challenges in the current trade landscape.

A fast switching thyristor with a superior trade-off property between the on-state voltage drop and the turn-off time could be fabricated by the proton irradiation method. After making symmetric thyristor dies with a voltage rating of 1,600 V from 350 $\mu$m thickness of 60 $\Omega$ㆍcm NTD-Si wafer and 200 $\mu$m width of n-base drift layer, the local carrier lifetime control by the proton irradiation was performed with help of the HI-13 tandem accelerator in China. The thyristor samples irradiated with 4.7 MeV proton beam showed a superior trade-off relationship of $V_{TM}$ = 1.55 V and $t_{q}$ = 15 $\mu$s attributed to a very narrow layer of short carrier lifetime(～1 $\mu$s) in the middle of its n-base drift region. To explain the small increase of $V_{TM}$ , we will introduce the effect of carrier compensation at the low carrier lifetime region by the diffusion current.ffusion current.t.

In phase-locked frequency synthesizers, a fast-lock technique is frequently employed to overcome the trade-off between a lock-time and a spurious response. The function of fast-lock in a conventional PLL (Phased Lock Loop) IC (Integrated Circuit) is limited by a factor of 16, which is usually implemented by a scaling of charge pumper, and consequently a lock time improvement of a factor of 4 is possible using the conventional PLL IC. In this paper, we propose a novel external active fast-lock loop filter. The proposed loop filter provides, conceptually, an unlimited scaling of charge pumper current, and can overcome conventional trade-off between lock-time and spur suppression. To demonstrate the validity of our proposed loop-filter, we fabricated an X-band frequency synthesizer using the proposed loop filter. The loop filter in the synthesizer is designed to have a loop bandwidth of 100 kHz in the fast-lock mode and a loop bandwidth of 5 kHz in the normal mode, which corresponds to a charge pumper current change ratio of 400. The X-band synthesizer shows successful performance of a lock-time of below 10 ${\mu}sec$ and reference spur suppression below -64 dBc.

This paper attempts to provide a way to improvement in trade & commerce between Korea and Russia, analyzing the influence of the circumstances of the Russian economy on economic relations between the two countries. The study briefly reviews the current situation of the Russian economy, and tries to examine the strong points to be considered as leverage for cooperation and the weak points to be overcome. Previous studies have determined that the Russian economy has unlimited potential for growth, because it is endowed with abundant resources, and has a government willing to reform for the opening of the economy, as well as high-quality labor. However, the economic structure is vulnerable to impact of the worldwide financial crisis. It is not possible to overlook its institutional fragility and vulnerability such as a corrupt bureaucracy or a relatively large black market. These undesirable factors may not only undermine the basis of Russia economy but also a hindrance to economic cooperation by increasing economic uncertainty. This paper attempts to analyze comprehensively the socio-economic factors that influence the open-economy of Russia, and to illustrate strategies for improvement in trade and commerce through the viewpoint of Korean firms that are already in business or are trying to enter in the near future. Some measures to improve their economic cooperation are suggested at the end.
