Proposal assessments for new weapon system development such as C4I system have been applying a qualitative assessment. The main problem of qualitative assessment is that the results vary depending on the evaluator's subjective preferences and priorities. Also, if there is no discrimination of technical skills degrade, the company will be selected by bid price regardless of technical power. In order to making a fairness, We need a method to compensate for the evaluator's subjectivity and to enhance discrimination. Previous standardization method is limited because targets of the proposal assessment are minority and have similar skill level. So, The new standardized evaluation methods applicable to the proposal was presented. This way is using the priority instead of the score and has better performance than existing methods as the target numbers are smaller.

총면적 37만㎢밖에 안되는 극동의 조그마한 섬나라 일본. 그러나 일본은 막강한 경제대국으로 그들이 이룩한 기술력을 높이 평가하지 않을 수 없다. 일본이 어떻게 서구 문명권 밖에서 으뜸가는 과학문명을 열었는가. 역사적 배경을 살펴보면.

고장력 강재 용접시의 문제점으로 용접균열, 용접부의 취화, 라멜라테어에 관해 그 발생기구와 대책을 기술했다. 고장력강재 용접기조물의 신뢰성과 안전성을 확보하기 위해서는 설계, 시공 단계에서 이상의 문제점에 관한 종합적인 평가와 배려가 이뤄져야 한다. 고장력 강재는 그 강 도를 높이기 위해 각종 합금원소를 첨가하거나 조직 열처리를 행하고 있기 때문에 용접상에 어 려움이 따르고 있다. 따라서 보다 사용성능이 우수한 구조물을 얻기 위해서는 강도가 높으면서도 용접성이 우수한 고장력 강재의 개발이 선행되어야 한다. 우리나라에서도 현재 60Kg/mm$^{2}$급 고장력 장재가 생산되고 있거니와 앞으로 더욱 고장도의 대입열 용접용 강재의 개발에 많은 노력을 기울여야 할 것이다.

This study analyses the necessity of the large-size shipyard and explores competitiveness factors of it. Furthermore, the competitiveness is evaluated and the economic feasibility of building and operation of shipyard is examined. As a result of AHP analysis of the determining factors of the competitiveness of the repairing shipyard, the importance of the factors was found in the order of arrival and departure safety, repair technology, dock and wharf facilities, repair cost, repair period (on time delivery), and repair parts supply. Moving distance, repair service quality, repair parts supply, arrival and departure safety, repair technology, dock and quay wall facilities, and repair period (on time delivery) were identified as key factors in the AHP analysis for competitiveness of the Busan Port repair shipyard to be built in the future. As a result of the analysing economic feasibility, the net present value of the Busan Port repair shipyard construction and operation investment project was KRW 435.6 billion, and the internal rate of return was 9.8%, higher than the social discount rate (4.5%), and the cost-benefit ratio (B/C) was high at 1.167. As a result of the study, the necessity and economic feasibility of the Busan Port repair shipyard are sufficiently ensured, and the competitiveness assessment was highly positive.

우리 나라는 각 대학이나 연구소에서 유능한 인력이 계속 배출되고 있고, 국산 기술에 대한 평가도가 날로 높아지고 있어서 레이저 산업의 전망이 대단히 밝다. 하지만 현재는 생산이나 수요 측면에서 모두 초기단계이며, 기술경쟁력도 선진국에 비해서 열악한 상태로 평가되고 있다.

Effective and Economic game evaluation before game publishing is very important for game development company. In this paper, we designed and developed an effective web based game evaluation system according to three major game genre including MMORPG, FPS, and web game. The proposed evaluation model consists of five evaluation items such as game interest, competitiveness, technology, earning power, and market value and has common evaluation items and independent ones according to game genre. To reflect characteristics of each game genre, we divided evaluation items into common evaluation elements and individual ones according to game genre. We applied the proposed system to two real games of a game development company and showed the result.

This paper represents the development of a CLS(Control Loading System) for a target a airplane (KT-1) with mechanical linkage reversible flight control system. The system is composed of mechanical frame, controller, sensing part to measure the force from the stick, driving system generating the reaction forces. The DS1103 DSP(Digital Signal Processor) of the dSpace Corp. was used as the controller. The control algorithm of the CLS and the operational environment including monitoring software and evaluation tools are described. The evaluation of the system was conducted according to the requirement specification. The results of the test were analyzed by comparing with the actual data of the target airplane.

A series of large scale plate loading tests are performed to assess bearing capacity characteristic of dredged and reclaimed ground that is reinforced by bamboo net and geotextile as a surface strengthen method. Bearing capacity ratio is distributed from 3.46 to 6.03 for bamboo net and from 2.19 to 3.59 for Geotextile In case of bamboo net, BCR was obtained from 1.6 to 1.7 times than Geotextile. As the comparison of each bearing capacity from test and theory shows, bearing capacity theory for geotextile was not suited for bamboo net. The bearing capacity analysis reinforced by bamboo net shows a good relationship between sand mat thickness (H) / bamboo net space (S), and bearing capacity ratio (BCR).

Many numerical analysis tools for predicting penetration speed of sheet pile are thought to be unreliable because they overestimate penetration speed for shallow depth of penetration. In order to overcome the defects of numerical analysis, lateral vibration model of sheet pile was suggested and energy consumption due to lateral vibration of sheet pile was estimated. Also, load reduction factor which explains reduction of vibratory driving force due to lateral vibration was introduced.
