양돈산업에서의 인공수정(Artificial Insemination, AI) 기술은 1994년 이후 본격적으로 국내 양돈농가에 보급되어 양돈 산업 발전에 기초가 되었다. 현재 우리나라에서 양돈분야에서의 AI 공급은 크게 3단계 그룹으로 분류되어 있다. 각 단계에서의 수많은 변수들로 인하여 현재까지 체계적이고 종합적인 관리의 시도는 이루어지지 않았다. 이에 웹을 기반으로 전국 AI센터의 통합정보시스템을 설계 구축하고 AI센터와 소비자 단계의 이력 관리를 지원하는 개선된 AI PigMoS 시스템을 제안하고 구현하였다. 본 논문에서 제안한 AI PigMoS 시스템은 웹을 기반으로 전국 AI센터의 정보를 통합관리 운영할 수 있으며, 또한 웅돈, 정액생산 및 판매관리 등에 대해서 이력추적을 할 수 있도록 설계 하였다. 이는 전국 AI센터의 효율적인 관리운영 뿐만 아니라 통합된 AI센터 관련정보의 분석 및 미래 예측자료 등으로 활용되어 효율적인 돼지 개량 체계를 구축할 것으로 기대한다.

As International arbitration has increased in popularity, there has been an expansion in the pool of arbitrators, and a commensurate diversification of not only the legal backgrounds but cultural backgrounds among themand among parties. As a result, there has been increased attention on the standards used to evaluate arbitrators' conduct and ethics, especially among them, 'Impartiality and Independence of Arbitrator' which is a precondition for an acceptable awards. There is no international treaty or code governing these issues. But the International Bar Association(IBA) seems to be leading the way such as establishing practical guidelines regarding to impartiality and independence of arbitrator. This article will review some theories, cases about impartiality and independence of arbitrator, and practical standards through the IBA guidelines. It is intended to provide specific guidance and criteria to the arbitrators, parties and counsels. And also it is expected to prevent unnecessary delays in arbitration proceedings in advance and filing for the annulment of arbitral awards because of lack of impartiality and independence of arbitrator as well.

Inertia welding is a solid-state welding process in which butt welds in materials are made in bar and in ring form at the joint face, and energy required for welding is obtained from a rotating flywheel. The stored energy is converted to frictional heat at the interface under axial load. The quality of the welded joint depends on many parameters, including axial force, initial revolution speed and energy, amount of upset, working time, and residual stresses in the joint. Inertia welding was conducted to make the large rotor shaft for low speed marine diesel engine, alloy steel for shaft of 140mm. Due to material characteristics, such as, thermal conductivity and high temperature flow stress, on the two sides of the weld interface, modeling is crucial in determining the optimal weld parameters. FE simulation is performed by the commercial code DEFORM-2D. A good agreement between the predicted and actual welded shape is observed. It is expected that modeling will significantly reduce the number of experimental trials needed to determine the weld parameters.

Global interests in RFID are increased and Korean government and companies make an active effort to propagate and spread RFID. Due to the overwhelming advantages of RFID system in comparison with existing bar code system, ripple effects on logistics sector among the utilizing fields of RFID technology are expected to be great, but application of RFID system is lowly progressed unlike the expectation of several experts. Therefore, this research extracts precedent studies on theoretical background, applying fields, promotion condition and domestic/foreign parts of RFID system, factors for operating domestic RFID system and effects and considers the effects of RFID's external variables on easiness and effectiveness of TAM. It confirms the relations of RFID applying effects for companies applying and utilizing RFID and verifies the relations among the effects for application of RFID system, accepting intention of RFID system and applying effects. Based on the results of analysis, it should play a role of good guide for all of companies and institution who will introduce RFID system to all of Korean logistics fields, make policies and systems which promote RFID acceptance nationally and socially and play a role of guide making confident climate for RFID technolog

The purpose of this study is to understand what we need to know about Microsoft's powerful web browser control so that we will be able to code and create a special-purpose browser. For this purpose, first of all, some literature survey was undertaken to study how the web browser looks like and is operated. One case design and coding was devoted to using visual basic to create our own web browser. The primary task of this job was accomplished with the form making up of a bunch of image controls, a status bar on the button, a picture box to contain the image buttons, the combo box, the command button and the menus and the statements shown in the above exhibits and tables respectively. After putting it all together, the form was implemented to see if it would work properly. The program was also enhanced to have a special purpose functions permitting filtering functions. The result was more or less successful, however has some limitations such as the simplicity of the programming structures and functions. However, this study is useful for understanding general outline of special-purpose web browser development.

Image Binarization is essential process in the digital image processing for the read out of a one-dimensional barcode. Local threshold method is suitable for binarization of a bar code. However, It has problem that processing time is slower than other binarization algorithm. Also, It's results not appropriate If the image has a noise. In this paper, we propose the modification method for solve these problems. Proposed algorithm help to improve the speed of local thresholding method using average image. Also, we proposed a high frequency filter to one-dimensional barcode for improvement quality of binary image.

This paper presents a study on the flexural ductility of reinforced concrete beams, 16beams with different concrete strength, reinforcement ratio, reinfo- rcement strength. For the purpose of inducing flexural failure, the reinforce ratio ($\rho$-$\rho$') was made not to be more than $0.75\rho$b in accordance with ACi code 318-89. From the test results, it is found that in case of a concrete strength increased from 240 to 650kg/$\textrm{cm}^2$, the displacement and curvature ductility factore are increased by about 31-231 percents. And also increased in case of increased from 650 to 900kg/$\textrm{cm}^2$, but the increasing ratio is gradually decreasing accoding to a concrete strength increases. And also found that as the Double Re-bar Ratio (($\rho$-$\rho$')/$\rho$b) increases, so the displacement and curvature ductility ratio would decrease, but in case of increased from 650 to /$900kg\textrm{cm}^2$ the decreasing ration is bigger than in case of increased from 240 to $650kg/\textrm{cm}^2$.

In ubiquitous computing environment, An RFID system will be the important way that recognizing an object instead of Bar-code system. But a privacy infringement problem is predicted between a tag and leader to be serious. There is many difficulty that just uses an existing research method because it has an Hardware restriction. Therefore we will suggest that A RFID Privacy Protect system using Hareware friendly security algorithm. we will use RC5 and CBC_MAC because the tag has hardware restriction .To implement, We will simulate and test on One chip microprcessor environment. In the result of the experiment, We will know that a suggested system solves privacy problem on RFID system that it was using CBC-MAC and RC5 security algorithm.

The container terminals in Korea usually adopts both the bar code and the image recognition systems at the gate complex to capture necessary information on containers passing through the gate. With the rapid advancement of Information Technology(IT) these systems, however, seem to make the user not satisfied due to the inherent limitations such as the long process time taken, low rate of recognition etc., This paper, therefore, examines the adoption of Radio Frequency Identification (RFID) technology to container terminals, and tried to get some implication for the way to improve the productivity of the terminal. The results imply that some improvement in the gate and storage yard operation is feasible by the benefit of using the information of vehicles and containers collected in advance by RFID technology.
