N/A The purpose of this paper is to develop a rational engineering conductive carbon filled composite through understanding of the effect of conductive carbon black. Polycabonate(PC), Acrylonitrile Butadiene Styrene copolymer(ABS) and PC/ABS resin were used as matrix of the conductive polymer composites. From the experimental results, PC filled with the fiber shaped carbon black showed a possibility to be a rational engineering conductive composite.

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.

The ending of the warranty under the current Multi-Housing Management Act has a lot of problem as it is very disadvantageous to the business entity and it makes hard for the contractor to finish the repair work. It is almost none for the business entity to get the written confirmation of the expiration of warranty liability from the client even though it sincerely completed their warranty obligation. It is because the client asks for the works other than fair repair arising from the defect in the work, such as the upgrade work for the enhancement of the value of their assets and the repair work which the client should take care before it issues the written confirmation of the expiration of warranty liability to the contractor. “So, though there is the law specifying this matter, the parties are relying on the unnecessary civil agreement. This leads to the big social and economic losses. If there is no agreement made between the client and the contractor, that leads to the legal dispute. This research on cases of 10 apartments shows that the types of works which the apartment residents ask for depend on the characteristics and conditions of the apartments and that they ask for various kinds of compensational works. In addition, it was found that there were many cases in which even the civil agreement is not recognized as the ending of the warranty obligation even if the proper procedure is taken for the ending of warranty by the contractor or business entity. If the collateral is to be offered to the client, the contractor would get more hard because there is the additional cost other than the warranty obligation, thus damaging the legal objective of the laws trying to minimize the damage made to the resident of the apartments. It means that the increase in the unnecessary warranty cost would lead to the increase in the selling price of apartment and the ending of the dispute through the civil procedure would make the Multi-Housing Act ineffective.
좋은 지리수업에 대한 현장 지리교사들의 개념: 포커스 그룹(Focus Group) 논의를 중심으로

매 차시 수업에 임하는 교사는 좋은 수업을 기대함에도 불구하고, 이에 대한 개념을 명확하게 정의하기에는 많은 어려움이 따른다. 본 연구에서는 1차로 전국에서 교사 경력이 풍부한 지리교사 30명에게 이메일을 발송, 좋은 지리수업에 대한 견해를 수집하였다. 그리고 그들이 제시하는 좋은 지리수업의 의미를 7개 주제로 구조화한 후, 포커스 그룹 논의를 실시하였다. 포커스 그룹 논의는 일대일 면접이나 설문지법보다 쟁점이 되는 주제들에 대하여 보다 심층적이고, 상호 의견을 교환할 수 있는 장점을 가지고 있기 때문이다. 포커스 그룹 논의에 참여한 7명의 교사를 중심으로 지리적 사고력의 의미, 지리 지식의 실생활과의 관련성, 교육매체 활용, 학생들의 수준에 따른 수업 운영, 교수 전환의 문제점, 비전공교사 문제 등에 대하여 중점적으로 논의하였다. 본 논의 결과를 통하여 부분적으로 좋은 지리수업의 의미를 밝힐 수 있었다. 지리교사들이 인정하고 합의할 수 있는 실천적 측면의 후속 연구가 지속되기를 기대한다. Although the geography teachers in each class anticipate a good instructional practice, it is difficult to define it clearly. In this study, I sent e-mail to the 30 geography teachers who have much experience as a teacher across the country, and then after I constructed the meaning of a good instructional practice, which the teachers presented, as 7 themes, I started arguing the Focus Group. To argue the Focus Group is more profound than one-to-one interview and questionnaire on the debated themes, and also it can have many merits to exchange their opinions. The seven teachers participating in discussing the Focus Group centered deeply on the meaning of a geographical thought, the relation between a geographical knowledge and a real life, the use of a education medium, the teaching management according to students` level, the problem of a didactic transposition, and the problem of teachers who didn`t major in geography. I could find the meaning of a good instructional practice through this debate. I anticipate the following study that geography teachers can recognize and agree to in the practical aspects.

Purpose: Juxtaglomerular cell tumor is a rare cause of secondary hypertension. Focal segmental glomerulosclerosis (FSGS) is a clinicopathological entity associated with renal insufficiency and proteinuria. The exact diagnosis and proper management are important in both juxtaglomerular cell tumor and FSGS. We experienced a 26-year-old male who complained of a palpable abdomen mass associated with proteinuria and hypertension. Ultimately, he was diagnosed with a juxtaglomerular cell tumor combined with FSGS after nephrectomy. After operation, his hypertension normalized, while his renal function deteriorated.

N/A Non-ceramic composite insulator has been interested in the power industry because of its good characteristics in mechanical properties, mass product and design availability. Also it is lighter, and less unexplosive, compared to a ceramic insulator. Especially, EPDM rubber composite insulator can be used for long-term in contaminated environments because of its hydrophobicity. This paper showed the rheological properties, the electrical properties, and contact angles to check the hydrophobicity and the recoverability of the EPDM compounds. Also, we investigated surface morphology of the compound by SEM.

The conventional Shewhart control chart techniques have found wide application in the manufacturing industries. However that chart is less sensitive to a very small shift and fraction nonconforming. Kim & Um(2012) first introduced the Z<sub>P</sub> control scheme for controlling a very small fraction nonconforming at the ppm level. The purpose of this paper is studying the exponentially weighted moving average(EWMA) control chart for detecting small shifts relatively and design the Z<sub>P</sub> - EWMA control charts combined with Z<sub>P</sub>. In addition, to obtain sensitivity to the initial phase of the process, the FIR Z<sub>P</sub> - EWMA control charts is analyzed to confirm the performance as actual case.
