Apartment building, which has been accompanied by economic growth in Korea, is a home of life and has the value overlapping as housing and assets. The improvement of consumer's eye level and development of related technology and related service development have positive function that enriches society and creates economic wealth. On the other hand, the clash and conflict between stakeholders increase social unrest and waste our competitiveness by economic loss. The term of warranty liability of apartment building is an important issue of defect lawsuits and is only a few quantitative standards. However, in this study, we examined the revision history of the law and ordinances for the reinforced concrete construction. As a result, establishing and revising the relevant standard, there is no definite basis system to support it. To improve this, the efforts to provide the standard for term of warranty liability and quantitative and objective basis to support it should be accompanied continuously.

In elevated irrigation aquaducts, one can observe a common damage pattern. That is, cracks, and crushing of concrete are usually repeated at a certain interval even if no faults are found in the design and construction of the structures. To investigate the causes of this damage, longitudinal deformations of several aquaducts have been measured. The analysis of the measured data suggests that the damages are mainly caused by cumulative repetition of extension and contraction due to temperature changes.

The number of defect disputes occurring in apartment houses is increasing year by year, and among them, disputes caused by defects in tiles account for 28.2% of the total, which is an important defect in tiles. A representative tile defect in the defect dispute is the lack of tile backfill. Another dispute occurred that the standards for each organization are different as the 100% standard of the Ministry of Land, Infrastructure and Transport's building construction standard and 80% standard of the Architectural Institute of Korea's Building Technology Guidelines. In this study, it was analyzed the relationship between the amount of tile backfill and the amount of tile defects based on 100 defect litigation court appraisal documents. It was observed that the amount of defect in tile works tended to decrease as the amount of tile backfill increased. By presenting an appropriate amount of mortar to fill behind tiles in a defect dispute, the effect of reducing the defect dispute can be expected.

This study has been carried out in order to observe the status of performance warranty contracting system currently being implemented at the advanced countries including Europe, U.S.A., and Japan, review the introduction feasibility and possibility. For this purposes this study has surveyed the concept and necessity of performance warranty contracting system as well as the status of domestic performance warranty contracting system. Especially the application environment for the performance warranty contracting system of Europe, U.S.A., Japan and Korea in terms of maintenance guarantee liability system, performance warranty regulations for design-build contracting system, selection method of successful bidder, performance warranty means, project contracting system including maintenance cost, and specifications and contract conditions for performance warranty system have been comparatively evaluated. And introduction methods of performance warranty contracting system were suggested.

In cases of wooden structure and wooden house installed on the outside, metal goods used for basic connection are usually screw bolts, strainless nails and general iron nails. As metal connections on wood are directly exposed to exterior environment, friction resistibility of nails on metal connections declines and continual defects on this are generated and maintenance for it is required. However, experiments and analyses for preparing basic data for improvement of the problems have been not conducted so far and wooden structures with defects are abandoned. Accordingly, by analyzing friction resistibility of connections by each kind of woods and metal goods, the study aims to suggest to use metal goods appropriately by kinds of woods and manufacture conditions with analysis on characteristics of resistibility of extracting nails for solving such problems and to secure basic data for establishing maintenance, repair and reinforcement plans.

지난해까지만 하더라도 PDA로 대표되던 포스트PC는 미래 '국내 IT 산업 성장의 핵심 견인차'로 주목받았다. 머지않아 PC산업의 일부분을 대체할 것이라는 장밋빛 전망에도 이의를 제기하는 사람이 드물 정도였다. 그러나 지금 상황을 살펴보면 가시적인 성과는 보이지 않고 기대했던 시장 또한 더디게 성장하는 상태다. 하지만 '디지털 융합현상'과 함께 '디지털콘텐츠'가 결합하면서 기업들은 '신대륙' 개척에 나서고 있다. 이에 산업자원부 산하 전자부품연구원에서 [Post PC백서]를 통해 국내 시장 현황과 기술동향, 소비자 조사 결과를 발표했다. 그 내용을 발췌 수록한다. 수요자 조사 및 시장현황 분석을 통해 국내 'Post PC'시장의 가능성과 하드웨어와 함께 발전하는 디지털콘텐츠의 미래도 엿보도록 하자.

The numbers of geogrid-reinforced walls are widely used in Korea. This papers present the results of two failure case histories of geogrid-reinforced segmental retaining walls. The geological background of the construction sites, detailed construction sequences, and the amount of rainfall were examined. The failure of these reinforced walls are caused by the improper drainage system and foundation treatment, too sharpened curvature of corner work, and too high height of wall.

오늘날 건축분야는 현대 산업사회의 복잡다양화된 구조내에서 여타 전문분야들과 함께 경제적으로나 사회적으로 그 역할과 책임이 날로 더해만 가고 있다. 그러나 건축분야의 경우, 하자에 대한 보상문제 등 건축활동에 따른 건축사들의 책임이 점차 증대되고 있는데 반해 이를 뒷받침해 줄 수 있는 제도적 장치가 미약한 실정이어서 이에 대한 법률적인 공동대처와 배상처리에 관한 전문적 연구가 있어야 한다는 지적과 함께 공제사업의 필요성이 대두되어 왔다. 이와 관련하여 본지에서는 '공제사업의 필요성'이라는 주제를 가지고 공제사업제도 도입에 따른 재원마련 방안과 운영방향 등에 대해 논의해 보고 아울러 국내 유사단체의 운영시스템과 현황, 선진외국의 사례 등을 비교ㆍ분석해 보고자 한다.

In this study, problems of software completeness appraisal are pointed out and their solutions are presented by analyzing appraisal cases and judicial precedents. Completeness appraisal, ready-made appraisal, defect appraisal, and cost appraisal have been classified as and have been evaluated with extant software completeness appraisals. From a legal point of view, and in judicial precedents, however, there is a big difference between the definition of completeness and the completion rate. This is because the degree of completeness is evaluated under the premise that the software's development is complete, whereas the ready-made appraisal inspects the development progress of unfinished software. Often, in cases involving software completion rate, the total completion level is calculated by weighting each step of the software development process. However, completeness evaluations use the software's realization-operation as its sole criterion. In addition, another issue not addressed in existing software completeness appraisal cases is that there is no mention of who is responsible for software defects, whereas in case law, the responsible party is determined by finding who caused the dispute. In this paper, we systematically classify these problems, and present a novel evaluation method that separates software completeness evaluations from software completion evaluations.

To solve some problems that reveals in the exiting stickiness problem of the housetop, the housetop finishing impact layer can be displaced by the existing concrete block. By doing in this way, this need is rising that the excess cost should be reduced and the materials should be recycled in repairing. According to the above, this study is going to suggest the basic data on building and using of the dry process method by estimating and analyzing a overall determinate quantity through the experiment on the insulation performance among the capacity items on the outside insulation waterproof dry process suggested. In addition, choosing the building method according to the use, the peculiar property and the importance of the building can be possible by analyzing the defect causes happening in the rooftop insulation and waterproof, suggesting the better method and classifying the most proper choosing methods for the need of the building according to the importance of the main factors.
