In Korea, the apartment supplier should satisfy the apartment residents' demand on the defect repair found in apartment housing by the law of Management of Apartment Complexs. But in the cost of defect repair, not only the actual defect repair cost, but also the cost of residents' complains are contained. So in this analytic study, the actual use state of defect deposite during 4~10 years after moving in are analysed base on actual data of 15 apartment complexes. In this study, about 66% of defect repair deposites are used to actual defect repair and only 34% of defect repair cost are spent to satisfy the demand of apartment residents'.

The purpose of this study is to suggest a defect-repair management and judgement of apartment housing for the private housing construction company. The objectives are : 1) to investigate how the defect-repair were managed and 2) to suggest the range, period of defect-repair and the proper managial size of housing company. Data were collected by the interviews from the heads of management departments of housing construction companies. Twenty-one companies selected were divided into three groups according to the amount of housing supply. Major result were as follows : 1) departments of defect-repair in housing construction company are divided into sub-system according to the size of housing supply. 2) the judgement of the range and period of defect-repair are extracted. They are, according to the order of their importance, constructional defect, functional defect, aesthetical defect and the defect in use.

This study intends to predict prospective defects and establish the plan of Preventive Maintenance through research and analysis of defect occurrences and their repair costs in the public equipment of ‘H’ apartment house from 1998 to 2001. According to results of the analysis, more than 90% of defects and their repair costs for 4 years of the building have occurred in heating, hot water and water supply equipments. In case of specific classification in each equipment, more than 60% of defects were found at hot water pipes and heating pipes, and their repair costs covered more than 60% of the total defect costs. After two repairs by ‘Preventive Maintenance’ had been performed in the year 1998, total defects and defects of each equipment each yew have increased in number from 1999 to 2001. But total repair costs and repair costs of each equipment have not increased as time has gone by, because repair costs have relationship with the price of materials and labor, the part of defect and the scale of repair.

We have developed an automated circuit defect repair method. We focused on the resist patterns on the circuit material layer of TFT substrates before the etching process. In this paper, we report on the repair method that utilizes the syringe system and the stability of the open defect repair process.

It is an social issue that is various claim related on the defect of apartment house. The cost of defect repair is the most important matter that residents dispute constructers with the huge time wasting and cost loss. For resolve the matter of defect claim, it must to be analyze to the cost property that study and find to pending issue about the cost of defect repair. Therefore this study is investigated the cost property of defect repair relation on correlation analysis and regression analysis around the judgement cost. Consequently, cost of the judgment is associated with cost of the accusation and cost of the defect repair, is recognizable as them that is closely connected. Meanwhile, the more time of take effect and time of lawsuit increase, the more cost of the judgment decrease by draw the regression equation. On the contrary, there are same aspects in the case on the cost of the accusation and cost of the defect repair.

This study investigated defect status by work type, based on the report data of defect inspection results, acquired by consumers' request to safety inspection agencies, before the expiration of legal defect repair warranty period. In fact, the data was not acquired by centering on suppliers, namely, construction companies in relation with the defects becoming causes to increase construction cost of apartments. This study aims to provide objective and basic data for quality improvement at construction stage and for solution to defect disputes. The study results are presented below: (1) The number of defect cases occurring from architectural work among total work types were 1,986, defect occurrence rate was 62.5%, and defect repair cost was KRW $25,851/m^2$, which stood at 78.2% of the total work types. This means the defect occurrence rate and defect repair cost in architectural work are bigger than those of other work types. (2) Major defects in architectural work were revealed in the following order: cracks from frame work, inferior interior finishing work, inferior finishing work of plaster/masonry works, water leak/damage from waterproof work and withering/omission from landscape work. The total repair cost of the major selected defects was KRW $12,220/m^2$, and was analyzed to take up 37% of the total defect repair cost.

This paper proposes a defect cell extraction algorithm for TFT-LCD auto-repair system. Auto defect search algorithm and automatic defect cell extraction method are very important for TFT-LCD auto repair system. In the previous literature[1], we proposed an automatic visual inspection algorithm of TFT-LCD. Based on the inspected information(defect size and defect axis, if defect exists) by the automatic search algorithm, defect cells should be extracted from the input image for the auto repair system. For automatic extraction of defect cells, we used a novel block matching algorithm and a simple filtering process in order to find a given reference point in the LCD cell. The proposed defect cell extraction algorithm can be used in all kinds of TFT-LCD devices by changing a stored template which includes a given reference point. Various experimental results show the effectiveness of the proposed method.

The number of disputes over defects after completion of construction work in apartment buildings is increasing every year. In this situation, the prediction of reasonable defect repair costs is very important. In this paper, we are going to collect basic data for predicting defect repair costs through the correlation analysis of the construction period and defect repair cost of apartment houses. For this purpose, first of all, the construction period and defect repair cost of apartment houses were analyzed to analyze the construction period for each type of work, the construction period for each project type, and the construction period for each standard calculation. Next, the correlation between defect repair cost and the independent variables of the candidate was conducted. According to the analysis, the ratio of framing air, the ratio of finishing air, and the number of delay days showed strong correlation.

Defect problems happening in the course of stressing quantity expansion of residence supply due to lark in maintenance are intensifying insincerity of construction business resulting from the psychological and economic damage, and there are many quarrel between residence suppliers and consumers. Because an apartment house's qualify is decided by various elements from design, to lotting-out, construction, and after-management, it is limited to express house capacity and standard to appraise defect objectively and quantifiably. The bound of defect and the period of guarantee expressed cleary in regulation of apartment house lack in quantifiable concept, and guarantee of defect is composed of a general concept. Therefore the big difference in opinion about defect and the bound of repair makes repair process slow and only to increase social costs. This research will give residence suppliers and consumers a resonable way to solve repair process during tile obliged period of guarantee since moving into from a process which are design, planing, construction, and after management. Furthermore it will present each business and role to conclude defect repair easily, so I planed to promote maintenance after conclusion of defect repair.

Decree on the Management of Apartment Houses. Article 36 (Liability for warranty Repair Defects), Article 37 (About Repair Defect, etc), and its implementing ordinances, Article 36 (Term of warranty liability) Article 37 (Defect criteria), Article 38 (procedure of Repair defect), Article 39 (type of warranty liability), Enforcement Rule Article 17 (Certifiation of warranty liability). On the basis of the upper Decree, In spite of Standard and forms of 'Completion of Repair Defect' was exist, it was hard to receive 'End of Confirmation' in practice. The purpose of this study is to propose basics in order that Practitioners can apply problems and improvements about Decree on the Management of Apartment Houses.
