  • 최근 발생한 건축물 붕괴 및 안전사고 사례의 주요 원인으로 건설용 강재의 품질문제가 꾸준히 제기되고 있다. 이에 따라 건설용 강재에 대한 자재관리, 유통관리, 시공관리를 통한 품질확보 이슈가 주요 문제로 떠오르고 있는 실정이다. 그러나 건설용 강재의 품질관리 방안은 기술적인 생산, 공정관리에 국한되어 있어 최근 발생하는 각종 부적합 철강재 관리에 대한 대안을 제시하지 못하고 있다. 따라서 본 연구에서는 건설관련 제도정책 측면에서 건설용 강재의 품질개선 방안을 제시하고자 한다. 건설용 강재관련 전문가 심층면담을 통한 제도개선 과제 아이템을 발굴하고, 이를 구조화된 AHP분석을 통해 기대효용성을 고려하여 최우선 중요과제를 도출한다. 또한 응답자를 분류하여 기업과 학계/연구계의 의견을 비교 분석하여 시각차와 시사점, 향후 개선방안에 대한 로드맵을 제시하였다. 본 연구에서 도출된 우선순위 제도개선과제들은 향후 건설용 강재의 품질향상을 위한 정책적 의사결정의 기초자료로 유용하게 사용될 수 있을 것으로 기대한다.

  • This is an extended paper explaining the role of E-learning and quality development in the current situation. Amid Covid:19, E-Learning has achieved a new miles stone in imparting education and all levels of institutions have transformed their learning platform from face to face to virtual learning. In this scenario E-Learning is facing two major challenges, first to ensure the ability of computer systems or software to exchange and make use of information on virtual platform (interoperability) and secondly, developing quality learning through e-Learning. To impart learning and teaching (L&T) through E-learning, Middle East University (MEU) has adopted Learning Management Services (LMS) through Blackboard. The university has three types of L&T methods; full online, Blended and Supportive. This research studies the concept, scope and dimensions of interoperability (InT) of E-Learning in MEU then the connection and interdependence between with quality development. In this paper we have described the support and the importance of finest standards and specifications for the objectives of InT of E-Learning and quality development in MEU. The research is based principally on secondary data observed from MEU E-Learning deanship. Also sample of 20 E-Learning experts at MEU were given closed ended as well as semi closed questionnaires for evaluating the assurance of InT of E-Learning and quality development. These experts are mainly certified online facilitators and admin staff. Results provide the verification of application and presence of InT of E-Learning and assured the quality development process in MEU.

  • In the manufacturing process the most widely used $\bar{X}$ chart has been applied to control the process mean. Also, Accelerated Life Test(ALT) is commonly used for efficient assurance of product life in development phases, which can be applied in production reliability acceptance test. When life data has lognormal distribution, through censored ALT design so that censored ALT data has asymptotic normal distribution, $ALT\bar{X}$ control chart integrating $\bar{X}$ chart and ALT procedure could be applied to control the mean of process in the manufacturing process. In the situation that process variation is controlled, $Z_p$ control chart is an effective method for the very small fraction nonconforming of quality characteristic. A simultaneous control scheme with $ALT\bar{X}$ control chart and $Z_p$ control chart is designed for the very small fraction nonconforming of product lifetime.

  • The objects, which can be personal digital assistants, electronic rings, doors or even clothes, offer embedded chips with computation facilities and are generally called artifacts. I later realized that this was not so the real problem is actually authentication. Recent results indicate scalability problems for flat ad hoc networks. Sensor network achieves function that handle surrounding information perception through sensor and sensed information to network that is consisted of sensor nodes of large number. Research about new access control techniques and height administration techniques need authentication information persons' certification assurance level classification in sensor network environment which become necessary different view base with authentication information at node for application of AAA technology in USN environment that must do authentication process using information that is collected from various sensor mountings. So, get base authentication information in sensor type and present weight grant model by security strength about authentication information through information who draw. In this paper collected information of sensor nodes model who give weight drawing security reinforcement as authentication information by purpose present be going to. and Must be able to can grasp special quality of each sensor appliances in various side and use this and decide authentication assurance level for value estimation as authentication information elements. Therefore, do to define item that can evaluate Authentication information elements thus and give simple authentication assurance level value accordingly because applying weight. Present model who give authentication assurance level value and weight for quotation according to security strength.

  • The variable sampling inspection scheme with screening for the purpose of assuring the upper limit of maximum expected surplus loss after inspection has been proposed. In this inspection scheme, it has been assumed that a product lot consists of products manufactured through a single production line and lot quality characteristics follow a normal distribution. In the previous literature with respect to inspection schemes, it has been commonly assumed that lot quality characteristics obey a single normal distribution under the condition that all products are manufactured in the same condition. On the other hand, the production line is designed in order that the workload of respective processes becomes uniform from the viewpoint of line balancing. One of the solutions for the bottleneck process is to arrange the workshops in parallel. The lot quality characteristics from such a production line with the process consisting of some parallel workshops might not follow strictly the single normal distribution. Therefore, we expand an applicable scope of the above mentioned variable sampling inspection scheme with screening in this article. Concretely, we consider the variable sampling inspection with screening for the purpose of assuring the upper limit of average outgoing surplus quality loss in the production lots when the lot quality follows the mixed normal distribution.

  • The progressive die performs a work of sheet metal processes with a piercing, notching, embossing, bending, drawing, cut-off etc. in many kinds of pressing. Now a days, these processes have been evaluated as a advanced tooling method to increase the productivity and high quality assurance. The first step analyzing of die design is production part review, then the arrangement drawing of product design and strip process layout design should be done as a next steps with a FEM simulation for its problem solution. After upper procedure were peformed, it was started to make the die, then tryout and its revision of the die and product quality, safety, productivity etc. were done continually. For the all of these process, we mobilized the theory and practice of sheet metal forming, die structure, the function and activity of die components, and the others of die machining, die material, heat treatment and know‐how so on. In this study the features of representative are production part analyzing through the FEM simulation of bending area with a considering spring back problem by DEFORM.

  • Despite of the vibrant nature of the fitness industry, there has not been a sustained effort to understand the dynamics of the industry, particularly with reference to the quality of services offered in that industry. The purpose of this paper is to present a system based process model of quality in health/fitness services. The characteristics of the organization, the service employees and the client are the inputs into the service encounter where the service is produced (i.e., the throughput). The output is the quality of the service. The extent of quality perceived by both the service provider and the client is said to influence the satisfaction of the respective parties, and subsequent motivation to participate in the production of quality in the service. The model also suggests that physical environment as well as other customers and their behaviors influence customer perception of service quality. The quality of service is enhanced through the quality assurance practices of the organization and the feedback from client. Further, the input, throughput, and output in our model reflect (a) quality of the design of the service delivery system, (b) objective quality of the product, and (c) quality as perceived by client. The specific attributes of the design element (i.e., organization, service employee, and the client) are elaborated upon. It is suggested that the organization can assure quality by seeking feedback from clients and service employees, monitoring the service production phases, and managing inter-customer interactions.
