  • The genus Entomognathus Dahlbom 1829 is recorded for the first time in the Korean Peninsula, represented by the species Entomognathus brevis (Vander Linden, 1829). This species is trans-Palearctic in distribution ranging from northern Africa, through Europe, eastward to the Far East, and sole representative of the genus in the Far East. Of which occurrence in the Russian Far East, northern China and Japan were well documented, but nothing has been known so far in the Korean Peninsula. In this study, distributional range of E. brevis is expanded to South Korea in the Far East. Taxonomic information of the species and a revised key to genera of the tribe Crabronini occurring in the Korean peninsula are given.

  • The comprehensive review of the STCW 1978, as amended in 1995 and associated Code was carried out from 2006 to 2010. These amendments will have a certain degree of impact on Maritime Education and Training(MET) institutes in terms of education and training of seafarer worldwide. Particularly, the Far East region countries are effected more than other regions since they covered about 30% of officers and 37% ratings in the world. In view of these facts this dissertation conceived to analyze the problems in the Far East main seafarer supply countries faced the implementation of "STCW Manila Amendments" To analyze these problems, this dissertation carried out questionnaire research to 7 targeted main MET of major Far East seafarer supply countries. After research this dissertation suggests the possible solutions such as, Joint On-Board Training Center; Joint Asia Maritime E-learning Systems; methods to reducing work-load, ship inspection burden and determine mandatory minimum safety manning standards in a safe way; technical cooperation fund to installation of training equipment; and clarify vague terminology of STCW Manila Amendments, to solve problems identified through the questionnaires.

  • There is no establishment of common plans fer the equitable use of frequency bands by terrestrial radiocommunications services in areas of far east countries including Korea. Main purpose of this paper is to propose the coordination procedure and related remarks between terrestrial wireless services in far east countries. In order to achieve this purpose, not only ITU-R regulations and recommendations on coordination but also agreements between some European countries and between northern American countries have been carefully reviewed and analyzed.

  • Anisotropic diffusion is a selective smoothing technique that promotes smoothing within a region instead of smoothing across boundaries. In anisotropic diffusion, the rate of smoothing is controlled by the local value of the diffusion coefficient chosen to be a function of the local image gradient magnitude. El-Fallah and Gary E. Ford represented the image as a surface and proved that setting the inhomogeneous diffusion coefficient equal to the inverse of the magnitude of the surface normal results in surface evolving speed that is proportional to the mean curvature of the image surface. This model has the advantage of having the mean curvature diffusion (MCD) render invariant magnitude, thereby preserving structure and locality. In this paper, the proposed MCD model efficiently reduces diffusion coefficient at the thin edges using the smoothness of the surface.

  • The Russian Far East Region covers an area of 6 Million and 216 thousands km2 and it is as vast as 36% of the Russan Federation on one hand. And this region also exists in a very severe climate condition as 90% of the region is covered with permanently frozen land on the other. This vast region has many of the world's richest natural resources : woods, fish, non-metals, energy resources, and other. The Russian Far East Region is prompts to participate in the world economy, specifically Asian and other Parcific Natiops along with the recent changes in the national structure of Russia. Although the transition to market economy and foreign investment in Russia is not sufficient, the time has come for us to actively promote technological exchanges with Korean and Russian Far East Region which are of our prosopective neighboring countries and seek for mutural relationships with us.

  • Release competition and development of eco-friendly vehicles have been conducted violently also automaker, it will be a high growth industry of the charger and battery, which is the driving source of the motor of an electric vehicle. Reduces the on-resistance power elements DC - DC converter for battery charger for electric vehicles, must minimize switching losses. Should have a low on-resistance power than existing products. Compare the Super Junction MOSFET and Planar MOSFET, As a result, super junction MOSFET improve on about 87.4% on-state voltage drop performance than planar MOSFET.

  • This paper presents an algorithm for acquisition of linear segments of building from edge pixels using Kalman filtering. We can obtain the accurate position of building corners from the linear segments of building. The corner points are used to calculate the position of building corners in world coordinate using stereo vision technique. The algorithm has been applied to pairs of stereo aerial images and the result showed accurate linear segment detection from edge pixels of roof boundaries.
