  • Product liability law lies at the center of the modem world. This law concerns liability for damages arising from the commercial sale of a product that causes personal injury or property damage because it was defective or falsely represented. One engaged in the business of selling or otherwise distributing products who sells or distributes a defective product is subject to liability for harm to persons or property caused by the defect. In short, product defectiveness is the heart of products liability law. Regardless of the underlying cause of action, the plaintiff in nearly every products liability case must prove that the defendant's product contained an unnecessary hazard that caused the harm. The purpose of this paper is to clarify the meaning of the product defectiveness to products liability claims in China. In China, Product to include most movable personal property, but to exclude services. And a product is defective when, at the time of sale or distribution, it contains a manufacturing defect, is defective in design, or is defective because of inadequate instructions or warnings.

  • Public domain defect data sets, such as NASA data sets which are available from the NASA MDP and PROMISE repositories, make it possible to compare the results of different defect prediction models by using the same data sets. This means that repeatable and general prediction models can be built. However, some recent studies have raised questions about the quality of two versions of NASA data set, and made new cleaned data sets by applying their data cleaning processes. We find that there are two ways in the NASA MDP versions to determine the defectiveness of a module, 0 or 1, and the two results are different in some cases. This serious problem, to our knowledge, has not been addressed in previous studies. To handle this ambiguity problem, we define two kinds of module defectiveness and two conditions that can be used to determine the ambiguous cases. We meticulously analyze 5 projects among the 13 NASA projects by using our ambiguity analysis method. The results show that JM1 and PC4 are the best projects with few ambiguous cases.

  • The injection molding process is able to produce high precision manufactures as a single process with fast speed. However, the prices of both the mold and the molding machine are expensive, and the single process is very complex and difficult to compose of the exact relationship between the process setting conditions and the product quality. Therefore, the quality of a molded product often depends on a skillful engineer's operations in the design of both parts and molds. In this paper, the relationship between the process conditions and the defectiveness is built for better manufactures under settings of the appropriate parameters, and so it can reduce the setup time in the injection molding process. Quality Function Deployment (QFD) provides severe defectiveness factors along with the related process parameters. Also, neural networks estimate the relationship between defective factors and process setting parameters, and lead to reduce the defectiveness of molded parts.

  • A safe and secure civil aviation system is a critical component of the nation's overall security, physical infrastructure, and economic foundation. Although it is not fully known at this time what actually occurred or which of the weaknesses in the nation's aviation security apparatus contributed to the terrible events of 11 September in the U.S.A., it is clear that serious weaknesses exist in our aviation security system including regulation system. Actually, defectiveness of regulations structure and contents concerned in aviation security were discussed in various studies. On this study, we have identified defectiveness in aviation security regulation system by the comparative study between 14 CFR and Korean regulations. Finally, we are to provide some suggestions and alternatives to improve aviation security regulation system in this country.

  • In weaving welding where a V groove exists, the heat input distribution is an important factor that determines the defectiveness of the bead shape, undercut and over-lap. In this study, the amount of heat input, which is determined by the welding current, voltage, speed and weaving conditions is calculated through mathematical development and numerical methods. Furthermore, the heat input distribution as a two- dimensional heat source was observed when applied to each groove.

  • This paper proposes an additional forward error correction (FEC) layer to compensate for the defectiveness inherent in the conventional FEC layer in the Long Term Evolution specifications. The proposed additional layer is called a graceful degradation (GD)-FEC layer and maintains desirable service quality even under burst data loss conditions of a few seconds. This paper also proposes a non-delayed decoding (NDD)-GD-FEC layer that is inherent in the decoding process. Computer simulations and device-based tests show a better loss recovery performance with a negligible increase in CPU utilization and occupied memory size.

  • 본 연구는 산지황폐계류에 시공한 사방공작물이 계곡생태계에 미치는 영향을 분석하고자 시공 전후를 기준으로 조사지점별로 저서성 대형무척추동물의 출현종의 변화분석 및 생물학적 수질평가를 실시하였으며, 그 결과는 다음과 같다. 시공 전 출현한 저서성 대형무척추동물의 총 수는 4문 6강 11목 22과 25종 3,086개체였으나 시공 후 조사에서는 4문 6강 10목 17과 19종 1,208개체로 감소하였다. 특히, 직접적인 사방공작물의 시공이 이루어진 조사지점에서는 시공 후 생물종이 전혀 출현하지 않거나, 극소량만이 채집되어 서식종의 현존량을 기초로 하는 다양도 지수, 풍부도 지수, 균등도 지수가 감소 또는 산출되지 않았다. 저서생물의 군집분석 결과 및 저서성 대형무척추동물의 생태점수(ESB)는 모든 조사지점에서 시공전보다 시공 후에 오수생물계열, 환경상태, 수질등급과 같은 계곡환경질이 저하된 것으로 나타났다. 즉, 시공전 상류는 양호 및 다소 양호, 중류는 다소 불량, 하류는 불량 및 매우 불량으로 분석되었으나, 시공 후 상류 일부 지역을 제외한 나머지 수역은 매우 불량으로 분석되었다. 또한 대상 계류의 수질등급의 경우 시공 전에는 $I{\sim}III$등급 사이로 분류되었으나, 시공 후 대조군을 제외하고는 모두 $IV{\sim}V$등급으로 악화되었다 이와 같이 사방공작물의 시공후 모든 조사지점에서 발생한 저서성 대형무척추동물의 서식 환경 파괴는 개체수의 감소와 수질악화로 이어졌다. 이 결과는 사방공작물의 시공 직후에 조사 분석한 것이므로, 향후 장기간의 모니터링을 통하여 시공한 사방공작물의 재해방지 효과와 함께 계류 생태계의 회복과정에 대한 지속적인 연구가 이루어져야 할 것이다.

  • Freed from its traditional confinement to the human body, postmodernism in fashion exposes the defectiveness of body and abstracts from the body under. Deformation of the body denotes the break away from the idealized and standardized body for mass productions. It tends to experiment with extreme exaggeration in form, refusing to subscribe to the traditional values that build on the balance and symmetry of the body. Bodily deformation carried out historical and cultural pastiche opposes the sartorial convention and symbolism which results in the discord between signifiant and $signifi{\acute{e}}$ of clothing. As a type of intimate architecture, fashion always mediates the dialogue between clothes and body, or fashion and figure. My study suggests a framework to analyze bodily deformation as pastiche, focusing on the relationship between clothes and the body. In order to inquire the deformation of the body in fashion, my study examines subjects of the fashion collections of the turn of the 21st century, using the method of literature research and content analysis.

  • In the process to design a product, the values of the product will be designed must be considered in respect to the multi-dimensional properties consisted of subjective and objective attributes. As same reason, methods to evaluate the design alternatives in the process must evaluate the overall attributes and relationships among its, also. In this paper, the defectivenesses of evaluation methods in the process of product design are summarized. One of the severe defectivenesses of the methods is the insufficient rationality of calculation procedure. Then, we introduce the developed quantitative evaluation method to accomodate this defectiveness and to be considered a evaluator's feeling or ambiguity when evaluating design alternatives by means of fuzzy theory, and suggest it's application steps on the process of product design to be used easily.
