  • In this paper, slack is computed from a comparison of the cable pay out rate and the ship ground speed in accordance with laying conditions, and the speed controller of the cable engine based on an H(sub)$\infty$ servo control id designed for adjusting the cable engine in order to lay a desired amount of slack. The controller is designed for robust tracking of the cable engine under disturbances. The performance of the designed controller is evaluated by computer simulation, and, consequently, a feasibility study for laying the submarine cable stably is done through analyzing simulation results.

  • 클라우드 컴퓨팅은 사용자의 요구에 따라 IT서비스가 생성 및 조정되는 pay-per use 모델을 도입하였다. 그러나 서비스 제공자는 아직도 물리적인 인프라로 인해 발생하는 제약조건들에 대해 관심을 갖고 있다. 필요한 QoS나 SLA를 만족시키기 위해서는 가상화된 자료들이 에너지 소비량을 최소화시키면서 시스템 성능을 최대화시키기 위해 조정되어야 한다. 본 연구는 ANN을 사용하여 클라우드 환경에서 가상화된 자원들을 조정하기 위한 예측적 SLA 어웨어 방안을 제시한다. Qos를 유지하고, 성능과 에너지 효율간의 최적화를 위해서 서버 활용 임계치는 물리적 자원의 소비에 따라 동적으로 적용한다. 또한 많은 자원을 소비하는 VM들은 능력있고 평판이 좋은 호스트에 할당함으로써 부족한 프로비전닝을 방지한다. 제안한 기법의 성능을 평가하기 위해, 이질적인 클라우드 환경에서 최적화되지 않은 전통적인 접근방법 및 기존의 기법들과 비교하였다.

  • 본 연구는 콘크리트 포장의 지불규정 인자 중 콘크리트 휨강도와 표면 평탄성이 콘크리트 포장 공용성에 미치는 영향에 대하여 분석하고, 이러한 인자에 대한 지불규정을 적용할 때 인자의 크기에 따른 적절한 허용범위를 결정하는 근거를 마련하기 위하여 수행되었다. 콘크리트의 휨강도에 대하여 AASHTO, 지수형, 선형 피로파손 공식 등의 공용성 모델을 이용하여 분석을 수행하였으며, 콘크리트 포장의 표면 평탄성에 대해서는 PSI, IRI, PrI 등의 평탄성 지수와 AASHTO 피로파손 공식을 사용하여 분석을 수행하였다. 연구결과, 휨강도의 허용 기준은 휨강도 손실률(손실량/휨강도)을 기준으로 하여야 하며, 휨강도 손실률이 증가할수록 설계수명이 선형으로 감소하기 때문에 이에 적절하게 공사비를 차감 지급해야 하는 것을 알 수 있었다. 표면 평탄성은 초기 평탄성이 우수할수록 평탄성지수의 손실률을 크게 허용해야 하며, 휨강도와 같이 평탄성 지수 손실률과 포장 수명 감소가 선형으로 비례하므로 공사비 차등 적용도 이에 적절하게 하여야 한다는 것을 알 수 있었다.

  • Purpose: The purpose of this study is how Chinese users' personal traits affect the intention to use mobile payment. This research selects personal innovativeness and habit of cash payment as personal traits, and considers perceived risks and relative advantage as personal beliefs. In addition, the research divided perceived risks into three multi-faceted risks, which are privacy risk, financial risk and performance risk. Methods: The method of this study used questionnaire survey to collect 241 data on users' perception on mobile payment, and also used a structural equation modeling method. Results: The result of this paper shows that all hypotheses are statistically significant except 4 hypotheses. Conclusion: The result of this study found that personal innovativeness is negatively related with all 3 kinds of perceived risks as anticipated. And Chinese users' traditional habit of cash payment negatively affects intention to use mobile payment but is not statistically significant affecting three perceived risks. Among perceived risks, privacy risk is the most negatively influencing factor to relative advantage.

  • Recently, as people pay attention to the environmental pollution, the emissions of diesel engine have been a serious problem. We carried out the performance evaluation test of Diesel Oxidation Catalysts (DOC) for HSDI diesel engine equipped vehicles. The DOC, basically coated with Pt catalyst, was manufactured with various washcoat materials. It was found that CO conversion efficiency depends on temperature, but THC conversion efficiency is dominated by temperature and space velocity. The THC and CO conversion efficiencies of aged catalysts were increased with additions of $ZrO_2$ and zeolite B in the washcoat. We found that DOC performance changes with coating techniques, even through it has same washcoat materials. The DOC coated by high temperature washcoat coating technology showed good conversion efficiency than low temperature washcoat coated DOC.

  • Purpose: This study aims to empirically analyze the effect of information sharing on the two dimensions of trust and logistics performance in the relationship between firms in the supply chain. Research design, data and methodology: In this study, information sharing is a variable for information competency of the entire supply chain. Moreover, we classified trust into quantitative and qualitative trust and analyzed the two paths through which information sharing reaches logistics performance. To examine these correlations, we conducted a survey among professionals in supply chain-related departments in South Korea. Based on 350 completed questionnaires, we tested the hypotheses with structural equation modeling using SPSS 18.0 and AMOS 18.0. Results: We found that information sharing has a significant positive effect on trust and logistics performance, which is a typical index of supply chain performance. These results show that information itself is considered a partner to a firm's competencies in operating the supply chain and plays a major role in forming the other's competencies and trust for the present and future. Conclusions: As these competencies and trust consequentially affect logistics performance, supply chain managers must pay attention to the importance of information competency and consider ways of promoting it to improve logistics performance across the entire supply chain.

  • This study aims to probe into the influence of new product design and new product development process management on development performance. The research finding demonstrates that product design reveals positive and significant influence on new product development performance. Through statistical analysis, this study finds that companies in Taiwan value new product design. When companies value it more, they tend to have better new product development performance. With regard to the relation between new product development process management and new product development performance, the empirical results demonstrate that companies would pay more attention on new product development process management. With regard to new product idea and assessment, concept design and development, product function test and mass production in the market, through statistical analysis, this study finds that companies that value process management of new product development tend to have better new product development performance. As to the influence of new product design and new product process management on new product development performance, statistical analysis result demonstrates that the integration between new product design valued by companies in Taiwan and development process management would lead to significantly positive influence on new product development performance of the companies.

  • In the current pavement construction practice, the state agencies traditionally determine the quality of the as-constructed pavement mix based on individual mixture material parameters (e.g., air voids, cement or asphalt content, aggregate gradation, etc.) and consider these parameters as key variables to influence payment schedule to the contractors and the present and future quality of the as-constructed mixture. A set of empirically pre-determined pay adjustment schedule for each parameter that was differently developed and being used by the individual agencies is then applied to a given project, in order to judge whether each parameter conforms to the designated specifications and consequently the contractor may either be rewarded or penalized in accordance with the payment schedule. With an improved quality assurance system, the Performance Related Specification, the individual parameters are not utilized as a direct judgment factor; rather, they become independent variables within a performance prediction function which is directly used to predict the performance. The quantified performance based on the prediction model is then applied to evaluate the pavement quality. This paper presents the brief history of the quality assurance in asphalt pavement construction including the Performance Related Specifications, statistical performance models in terms of fatigue and rutting distresses, as an example of the performance prediction models, and envisions the possibilities as to how this Performance Related Specification could be utilized in other infrastructures construction quality assurance.

  • Recent increases in construction costs on Korean public works projects, largely due to change orders caused by poorly elaborated design, become a motivation of applying VE process in Korean construction industry. The Seoul Toll Plaza project, recently value analyzed by four VE teams, demonstrates how value management helps save time, money and increase functional performance. The objective of this project is to upgrade and expand existing pay and ticket booths system on "Kyungboo Express Highway", the main artery for the Korean peninsula linking Seoul to Pusan. The value management study generated several innovate alternatives capable of saving up to 50% of project cost from the baseline project plan.
