  • 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 numerical methods. Furthermore, the heat input distribution as a two- dimensional heat source was observed when applied to each groove. Therefore, a heat input control algorithm is suggested to prevent the defects generated from undercut or over-lap, which was verified through an analysis of the heat input distribution.

  • A company is liable for its products and has the responsibility to make good on any loss or damage incurred by the user of its product. The purpose of the Product Liability Act(PLA) is to protect consumers against damage caused by defective products, and contribute to the safety of the citizen's life and the sound development of the national economy by regulating the liability of manufacturers, etc. for damages caused by the defectiveness of their products. In this study, the cognition levels of consumers and producers for PLA were surveyed. The cognition levels of four factors of acknowledgement, comprehension, necessity and impact for PLA were assessed. The results were as follows : i) Acknowledgement and comprehension levels of consumer were assessed low but they assessed necessity and impact of PLA high; ii) Producers assessed necessity and impact of PLA higher than their acknowledgement and comprehension levels; iii) Overall cognition levels of producers were higher than those of consumers.

  • Quality assurance in the process of manufacturing high strengh bolt sets used in the frictional joints of structures in one of important concern to users as well as to manufactures. In case of occurrences of either defective or low-quality products, even if they are quite rare, some systematic means of localizing the cause-characteristics and matching to corresponding production process is necessary. Control chart of torque factor is the primary indicatir in finding defectiveness of the products. Use of correlation diagrams ofnhardness of the bolt set presents in part a way of screening the cause. Retest data of the bolt set provide additional ideas of localizing the cause, for which theoretical background is presented in this regard. A process-characteristics matrix relating the causes of low quality to the corresponding process of manufacturing, which is of prime importance for the feedback control of production, is also proposed. Finally general features of control to assure quality of the set is described.

  • 우리나라 형법 제10조 제1항에서는 "심신장애로 인하여 사물을 변별할 능력이 없거나 의사를 결정할 능력이 없는 자의 행위는 벌하지 아니한다"라고 규정하고 있다. 따라서 정신장애자가 행위 시에 책임능력이 결여되었다고 판정되면 형사처벌을 할 수 없다. 정신장애자에 대한 책임능력의 판단 문제는 형법학과 정신의학이 교차하는 영역에 존재한다. 정신장애로 인한 책임능력의 존부에 대해서는 최종적으로 법원이 판단하게 되지만 생물학적 요소인 정신장애에 대한 판단은 정신의학적 지식이 필요하고 이에 의존하는 것이 당연하다. 특히 국민참여재판의 시행으로 정신장애자의 정신감정 절차와 내용에서 변화가 요구된다. 일반시민들로 구성된 배심원이 재판의 심리에 참가하게 되므로 배심원이 정신감정의 결과를 이해하고 판단할 수 있도록 더욱 정확한 정신감정과 결과를 제출하는 절차의 개선이 필요하다. 형사사법절차에서 정확한 정신감정결과를 담보하기 위해서는 형사사법과 사법정신의학에 관한 일정한 교육프로그램을 이수한 정신과 의사 또는 심리학자로 구성되는 인력-풀을 구축하고, 인력-풀에 소속된 감정인을 선정하여 정신감정을 실시하는 것이 바람직하다. 나아가 국민참여재판에서 일반시민으로 구성되는 배심원의 비전문성을 고려해야 하므로 알기 쉬운 정신감정서의 작성과 제출이 요구된다. 정신장애 여부에 관한 배심원의 공정한 평결을 위해서는 정신감정서의 신속한 제출과 중요한 내용을 요약한 정신감성서의 제출, 배심원이 쉽게 이해할 수 있는 정신감정서의 작성이 필요하다.

  • Seoul Metro continuously converted the standard rail into continuous welded rail since the later part of 1990's, and currently, most of the sectors of the Seoul Metro are continuous welded rails. As the continuous welded rail is inhibited by the contraction and expansion force of the rail as well as rail-bed, this force is stored as the internal stress of the rail with the exception of portion of the both ends of the continuous welded rail. If the contraction and expansion of the rail is restricted, the internal stress, that is, the force in the direction of the axis, is proportional to the cross-sectional area of the rail. Therefore, with regards to the temperature changes, the internal stress changes in accordance with the type of rail, bolting apparatus, railroad tie and rail-bed. As such, the rail temperature becomes important data in securing the gap at the adjoining section of the rail in the standard rail section, and to determine the setting temperature for the continuous welded rail. In addition, it becomes basic data for maintenance of the track. Accordingly, this thesis introduces cases of installation of rail temperature detector in order to prevent and manage track defectiveness due to increase in rail temperature, and to utilize as basic data at the time of various construction and maintenance. Furthermore, this thesis aims to assist maintenance of track through systematic temperature management in the future by looking into means of its utilization.

  • Freed from its traditional confinement to the human body, postmodernism in fashion exposes the defectiveness of body and abstracts from the body under. As the 20th century art put premium on self-expression, the body itself became a powerful medium of expression in fashion. Using 'body' to analyze the clothing form, my study develops a framework by which to classify the fragmentation of the body in fashion. In order to inquire the formative style and aesthetic values expressed in fragmentation of the body in fashion, my study examines subjects from the discourse on the body to the fashion collections of the late 20th and 21st century, The results of the study are as follows. Fragmentation of the body in fashion means 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. The formative aspects of fragmentation are achieved through body casting, displacement, and deconstruction. The absence of physicality in fashion opposes the sartorial convention and symbolism that results in the discord between signifiant and $signifi{\tilde{e}}$ of clothing. Fashion continues to explore forms and images that transcend the traditional representations of the clothed body. 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 fragmentation of the body in fashion, focusing on the relationship between the clothes and body.
