우리나라는 비약적인 산업기술발전을 통해 선진국 진입을 눈앞에 두고 있다. 하지만 선진국 진입에 있어 크게 세 가지의 걸림돌이 있다. 첫째로는 세계시장 진입의 장벽, 둘째로 제조물책임법(PL법) 대응방안 미흡, 셋째로는 고객신뢰 및 자원의 한계 이다. 이러한 한계점으로 인하여 신뢰성경영시스템의 필요성이 대두되고 있으며 국내의 신뢰성경영시스템의 활성화는 필수 요소로 다가오고 있다. 본 논문에서는 신뢰성경영시스템의 활성화와 이를 위한 지표개발의 필요성 및 개발 방향성을 제시해보고자 한다.

As information-oriented industry has been developed and electronic devices has come to be smaller, lighter, multifunctional, and high speed, the components used to the devices need to be much high density and should have find pattern due to high integration. Also, diverse reliability problems happen as user environment is getting harsher. For this reasons, establishing and securing products and components reliability comes to key factor in company's competitiveness. It makes accelerated test important to check product reliability in fast way. Out of fine pattern failure modes, failure of Electrochemical Migration(ECM) is kind of degradation of insulation resistance by electro-chemical reaction, which it comes to be accelerated by biased voltage in high temperature and high humidity environment. In this thesis, the accelerated life test for failure caused by ECM on fine pattern substrate, 20/20μm pattern width/space applied by Semi Additive Process, was performed, and through this test, the investigation of failure mechanism and the life-time prediction evaluation under actual user environment was implemented. The result of accelerated test has been compared and estimated with life distribution and life stress relatively by using Minitab software and its acceleration rate was also tested. Through estimated weibull distribution, B10 life has been estimated under 95% confidence level of failure data happened in each test conditions. And the life in actual usage environment has been predicted by using generalized Eyring model considering temperature and humidity by developing Arrhenius reaction rate theory, and acceleration factors by test conditions have been calculated.

Industrial disaster caused the deaths of 2,114, construction workers among them was the highest of 621 deaths. In the construction industry, has established a number of safety alternatives to prevent accidents. But until now, the cause of the accident has stopped being superficial analysis, awareness on the root cause of the acciden did not reflect. In this study, we analyze the characteristics and causes in G contractors' safety accidents. And innovation strategy, organization-wide safety management system and detailed tasks to derive essentially was to prevent the occurrence of large construction companies. A lot of business for accident prevention effect was transient and formal, to reflect a management style and organizational culture, and try to prevent construction accidents. we will strive to prevent the disaster from the construction site through the improvement of these.

Because the difference between products and services are getting less and less, service and manufacturing companies’ efforts are increasingly focused on utilizing services to satisfy customers’ needs under today’s competitive market environment. The value of services depends on service reliability that is identified by satisfaction derived from the relationship between customer needs and service providers. In this paper, we extend concepts from the fault tree analysis for reliability analysis of tangible systems to services. We use an event-based process model to facilitate service design and represent the relationships between functions and failures in a service. The objective of this research is to propose a method for evaluating service reliability based on service processes using service blueprint and FTA. We can identify the failure mode of service in a service delivery process with a service blueprint. The fuzzy membership function is used to characterize the probability of failure based on linguistic terms. FTA is employed to estimate the reliability of service delivery processes with risk factors that are represented as potential failure causes. To demonstrate implementation of the proposed method, we use a case study involving a typical automotive service operation.

This study presents the effectiveness of a composite structure at improving blast resistance. The proposed composite structure consists of carbon fiber reinforced polymer (CFRP) and steel layers. While CFRP layer is used for blast energy reflection due to its high strength, steel layer is used for blast energy absorption due to its high ductility. A dynamic model is used to simulate the elastoplastic behavior of the proposed composite structure subject to blast load. Considering the magnitude variations of a blast event, the probability of failure of each layer is evaluated using reliability analysis. By assigning design probability of failure of each layer in the composite structure, the thickness of layers is optimized. A case study for the design of CFRP-steel composite structure subjected to an uncertain blast event is also presented.

Decisions on reliability screening rules and burn-in policies are determined based on the estimated reliability. The variability in a semiconductor manufacturing process does not only causes quality problems but it also makes reliability estimation more complicated. This study investigates the nonuniformity characteristics of integrated circuit reliability according to defect density distribution within a wafer and between wafers then develops optimal burn-in policy based on the estimated reliability. New reliability estimation model based on yield information is developed using a spatial stochastic process. Spatial defect density variation is reflected in the reliability estimation, and the defect densities of each die location are considered as input variables of the burn-in optimization. Reliability screening and optimal burn-in policy subject to the burn-in cost minimization is examined, and numerical experiments are conducted.

본 연구에서는 농산물 안전성과 농산물 가공식품 안전성이식품신뢰에 미치는 영향과 식품신뢰와 감정몰입 및 구매의향의 인과관계를 소비자의 경제력 규모에 따라 어떠한 차이가있는가를 확인하였다. 연구결과 고소득층에서는 농식품안전성이 식품신뢰에는 영향이 없는 반면, 중간소득층 및 저소득층에서는 영향이 있었다. 그러나 식품신뢰와 감정적몰입, 감정몰입과 구매의향, 그리고 식품신뢰와 구매의향 관계에서는 모든소비자계층에서 유의한 영향이 있는 것으로 확인 되었다. 연구에 대한 논의는 다음과 같다. 첫째, 소비자의 소득수준에 따라서 농식품에 대한 신뢰에 차이가 있다. 고소득층에서는 일반적인 농산물의 안전성에 대해 신뢰하지 않고 단지 가공식품에 대해서만 신뢰하는 반면, 중간소득층 및 저소득층에서는 농산물과 농산물 가공식품을 모두 신뢰하는 것으로 확인되었다.따라서 소비자를 소득수준에 따라서 고소득층과 중간소득층및 저소득층으로 구분하여 집단의 특성에 맞도록 시장을 세분화하고 적합한 마케팅전략을 적용하는 것이 바람직할 것이다.즉, 유기농식품을 포함한 친환경식품은 고가격전략을 추구하여 고소득층을 대상으로 소구하는 것이 바람직할 것이다. 이를 위해선 데이터베이스마케팅을 도입하여 고객명단을 분석한후 고소득층 소비자에게 Eco-partner 인증제도, 녹색시스템운영, 제품의 유해물질 관리, 친환경소재개발 등 친환경제품과그린마케팅, 그리고 친환경인증획득을 통한 친환경제품개발활동을 전개하고, 또한 생산자로서 책임을 다하는 기업임을 강조하여 고소득층과의 교감을 통해 친환경이미지제고활동을 전개하는 등 고소득층에 적합한 차별화된 마케팅활동을 전개하는 것이 중요하다. 둘째, 고소득층은 식품에 대해 신뢰를 한소비자는 직접적으로 구매의향을 나타내기 보다는 감정몰입이될 때 더 높은 구매의향이 있는 것으로 확인된 반면, 중간소득층 및 저소득층 소비자는 감정몰입이 중요하지만 이 요소가구매의향에 미치는 영향보다는 신뢰가 직접적으로 구매의향을일으키는 것이 더 높은 것으로 나타났다. 그러므로 소비자를분류하여 고소득층에게는 장기적 관점에서 평생고객 개념으로고객과의 관계관리를 지향해야 하는 반면에 중간소득층 및 저소득층은 일회성 고객으로 분류하여 즉각적인 구매로 연결될수 있도록 차별화된 고객관리가 필요하다. 따라서 고소득층고객은 식품에 대한 신뢰를 통해 고객이 감정적으로 몰입할 수있도록 제품에 대해 건강과 여유 등 삶의 질을 강조할 필요가있고, 중간소득층 및 저소득층에게는 즉각적인 소비가 이루어질 수 있도록 저가전략 및 판촉전략을 실행할 필요가 있다.

The lower trapezius muscle is an important stabilizer and primary mover of the scapula. The potential use of ultrasound imaging to evaluate scapular muscle function warrants investigation. The purpose of this study is to use ultrasound imaging for determining the effectiveness of 4 different isometric exercises for maximally activating the lower trapezius muscles in healthy subjects. Twenty-eight (14 men and 14 women) volunteers were recruited for this study. Thickness measurements of the lower trapezius muscles were recorded during 4 exercises: latissimus pulldown (LP), prone V-raise (PV), prone row (PR), and modified prone cobra (MP). Lower trapezius muscle thickness was measured 3 times by 2 investigators at a point 3 cm lateral to the lateral edge of the T8 spinous process. The order of 4 exercise execution was randomized for each participant. To identify statistical significance, one-way ANOVA with repeated measures was used with the significance level of .05. Intraclass correlation coefficient (ICC) for intra-reliability was .86~.98 and inter-rater reliability .83~.96 for the lower trapezius, respectively (p<.01). Thickness changes in the lower trapezius muscles between the relaxed and contracted states in men were as follows: LP (, 182%), MP (, 167%), PV (, 149%), and PR (, 133%). In women the values were as follows: LP (, 163%), MP (, 131%), PV (, 129%), and PR ( mm, 100%). Thickness of the lower trapezius muscles significantly differed between exercises in both the gender (p<.01). The LP was the most effective exercise for increasing the activation of the lower trapezius muscle in both the gender. We recommend performing the LP exercise for strengthening the lower trapezius muscles.
