자동차를 설계할 때에는 예술적, 기술적으로 뛰어나다 하더라도 공학적으로 실현이 가능하여야 한다. 또한 비용이라든가 품질도 중요한 고려사항이다. 하지만 이것들 보다 자동차 설계에서 더욱더 중요시되는 것은 안전이다. 사고 시 사람의 생명을 최대한 안전하게 보호할 수 있는가이다. 이번 연구는 'Design for Safety' 중에서도 보행자 안전을 고려한 자동차 설계에 관해 연구하고자 한다. 2005년 교통사고 통계에 따르면 차대사람의 사고발생건수는 총 46,594건에 사망자 2,457명 부상자 47,282명이다. 이는 한 해 전체 교통사고 발생건수에 21.8%를 차지하고 있다. 본 연구는 자동차 사고 중 보행자와 차량의 사고 유형과 상해부위를 파악하여 사례를 중심으로 살펴본 후 이를 자동차 설계에 반영하는 방법에 대한 연구이다.
Multi-criteria decision making is deducing the relativistic importance in the criterion of decision making and each alternative which is able to make a variety of choices measures the preferred degree in the series of low-ranking criterions. Moreover, this is possible by synthesizing them systematically. In general, a fun-diametral problem decision maker should solve for multi-criteria decision making is evaluating a set of activities which are considered as the target logically, and this kind of work is evaluated and synthesized by various criterions of the value which a chain of activities usually hold in common. In this paper, we study about effective consumer preference to towels made of paper according to the three kinds of intensities of products from some domestic company, using the AHP.
This paper introduces statistical test principles, statistical procedures and tests for exponential distribution. This paper also shows compliance test plans for success ratio and constant failure rate, and goodness-of-fit tests for Weibull distribution. Moreover, this paper presents procedures for comparision of two constant failure rates, and dependability of products containing reused parts.
This paper shows application guide of dependability data from the field, life cycle costing, and maintainability. Moreover, this study introduces mathematical expressions and predictions for reliability, availability and maintainability. This paper also shows compliance test procedures for steady-state availability, and application of Markov techniques.
This paper presents contents of certificates, and use for reference materials. This study also introduces general requirements for the competence of reference material producers. Lastly this paper shows general and statistical principles for certification of reference materials.
This paper introduces reliability stress screening(RSS) for electronic hardware and components. This study also shows reliability centered maintenance(RCM), and reliability growth models. Moreover, this paper presents goodness-of-fit tests and estimation methods of power law model.
The main objective of this paper is to provide analysis of obesity index of residents in six metropolitan cities. According to analysis of Rohrer Index, there was significant difference regionally between men and women in metropolitan cities. Through analysis of Drop Value, it was found that there were significant differences regionally between men and women in metropolitan cities on circumferences of chest, waist and buttocks. The result of this research can be utilized in manufacturing and design of uniforms and equipments for safety.
There are many Korea companies who are introducing many kinds of management renovation methods in order to attain more management achievement. So many personnels under CEO are frying to change themselves to fit those kinds of management renovation methods. Now, all kinds of books for supervisors have published, but it is not easy for those supervisors to understand those books as those books do not fit for their own companies situation. The best management methods in the best companies in U.S.A. actually can not be well introduced in Korea. So, the management methods should be changed with the environment's changing. Therefore, the company management is the process to suit the continue changing environment.
The Location Based Services (LBS) comprise spatial information and mobile technology allow users to receive various services based on Global Positioning Systems (GPS). Although, spatial information based services are very useful, it has lots of possibility to damage privacy protection. But the contents of the legislation by government have problems conflicted between protection of a person's location information and invigoration LBS. Therefore, in this study suggest a causal model to deal with user satisfaction and factors affecting spatial information based services to customer perspective. The proposed research model is tested empirically with one hundred and forty one usable questionnaires and partial least square (PLS) method. Experimental results showed that the usefulness, playfulness, and service quality play a prominent role in influencing the spatial information services satisfaction compared to other factors. But, easy of use and perceived risk are not significant.
The development of information technology, which has brought the fusion of broadcasting and telecommunication, wire and wireless communication and voice and data, is developing new fusions like home network which is composed of IT, construction, and home appliances. This trend is considered to continue and to make other new fusions based on previous ones. In this study, we investigate the roles of RFID middleware by identifying the relationships between the new expected fusions and RFID.
In spite of the development of the service industry, research on measuring customers' service satisfaction is far insufficient. Therefore, ways to measure the service qualify accurately need to be established due to the ambiguous types of service business. This research classifies the types of service business into service factory, service shop, mass service, professional service by using Schmenner's Service Process Matrix and conducts research on domestic literature that measured service satisfaction with Servqual and ServPerf. This study intends to suggest guidelines to measure customer satisfaction according to types of service business by researching ways to measure service satisfaction according to the types of service business and analysing the actual application methods based on a table that summarizes previous research on Servqual and Servperf.
오늘날 제품이 문제가 되는 경우는 별로 없다. 그런데 불행하게도 재화를 만들고 용역을 제공하는 많은 기업들은 제품 하나에만 관심을 쏟고 있다. 정작 중요한 것은 고객의 소리를 듣는 것이다. 서비스 산업에서 특히 이것은 아주 중요하다. 서비스 관련 여러 요소 가운데 중요도를 선정하여 서비스 품질을 린 프로세스적 사고로 서비스 요소중의 낭비를 제거 한다면 소비자에게 불필요한 서비스가 아닌 진정한 가치를 선사하는 일이 될 것이다.
