The successful operation of a product In service depends upon the effective provision of logistic support in order to achieve and maintain the required levels of performance and customer satisfaction. Logistic support encompasses the activities and facilities required to maintain a product (hardware and software) in service. Logistic support covers maintenance, manpower and personnel, training, spares, technical documentation and packaging handling, storage and transportation and support facilities.The cost of logistic support is often a major contributor to the Life Cycle Cost (LCC) of a product and increasingly customers are making purchase decisions based on lifecycle cost rather than initial purchase price alone. Logistic support considerations can therefore have a major impact on product sales by ensuring that the product can be easily maintained at a reasonable cost and that all the necessary facilities have been provided to fully support the product in the field so that it meets the required availability. Quantification of support costs allows the manufacturer to estimate the support cost elements and evaluate possible warranty costs. This reduces risk and allows support costs to be set at competitive rates.Integrated Logistic Support (ILS) is a management method by which all the logistic support services required by a customer can be brought together in a structured way and In harmony with a product. In essence the application of ILS:- causes logistic support considerations to be integrated into product design;- develops logistic support arrangements that are consistently related to the design and to each other;- provides the necessary logistic support at the beginning and during customer use at optimum cost.The method by which ILS achieves much of the above is through the application of Logistic Support Analysis (LSA). This is a series of support analysis tasks that are performed throughout the design process in order to ensure that the product can be supported efficiently In accordance with the requirements of the customer.The successful application of ILS will result in a number of customer and supplier benefits. These should include some or all of the following:- greater product uptime;- fewer product modifications due to supportability deficiencies and hence less supplier rework;- better adherence to production schedules in process plants through reduced maintenance, better support;- lower supplier product costs;- Bower customer support costs;- better visibility of support costs;- reduced product LCC;- a better and more saleable product;- Improved safety;- increased overall customer satisfaction;- increased product purchases;- potential for purchase or upgrade of the product sooner through customer savings on support of current product.ILS should be an integral part of the total management process with an on-going improvement activity using monitoring of achieved performance to tailor existing support and influence future design activities. For many years, ILS was predominantly applied to military procurement, primarily using standards generated by the US Government Department of Defense (DoD). The military standards refer to specialized government infrastructures and are too complex for commercial application. The methods and benefits of ILS, however, have potential for much wider application in commercial and civilian use. The concept of ILS is simple and depends on a structured procedure that assures that logistic aspects are fully considered throughout the design and development phases of a product, in close cooperation with the designers. The ability to effectively support the product is given equal weight to performance and is fully considered in relation to its cost.The application of ILS provides improvements in availability, maintenance support and longterm 3ogistic cost savings. Logistic costs are significant through the life of a system and can often amount to many times the initial purchase cost of the system.This study provides guidance on the minimum activities necessary to Implement effective ILS for a wide range of commercial suppliers. The guide supplements IEC60106-4, Guide on maintainability of equipment Part 4: Section Eight maintenance and maintenance support planning, which emphasizes the maintenance aspects of the support requirements and refers to other existing standards where appropriate. The use of Reliability and Maintainability studies is also mentioned in this study, as R&M is an important interface area to ILS.

In a time when product development cycles are getting shorter and shorter, many companies are making efforts to develop products with high reliability in a short period of time, accelerated life test is widely used as a method to quickly evaluate reliability. Accelerated life test reduces the test life or the life of the product from the observed data by shortening the lifetime of the product or abruptly lowering the performance under the worse condition than the actual condition in order to shorten the test cost or the test time. In this paper, BL3640A-06P+RB35, DC12V model, which is used in the support device of an automatic rotation type digital signage, which display various information such as textures and images on a display screen in a public place or a commercial space, BLDC motors were subjected to a constant stress test and at the rotational speed of 1rpm, $180^{\circ}$ rotation and reverse rotation under actual use conditions, the stress was imposed on the rotating speed of 2rpm and the weight of the actual installed product from 22.2kgf to 10kgf were installed. The lifetime of the actual use environment condition is 23,545 hours and the rotation speed is accelerated. The life time of the acceleration condition with the additional weight is 1,380 hours. The acceleration factor is calculated as 17.06, the one year guarantee test day is 235 days to 14 days, of the period from 470 days to 28 days, and the third year from 704 days to 42 days. The test date of the BLDC motor was tested on the shortened test date, and the rotational speed and the current value were measured. It is found that there is no defect even if it operates as the test date corresponding to the specified one year warranty period and the 3 year accelerated life test which is experimented. Using the statistical technique of the regression analysis the expected time for the motor to defect to #4 samples was 20 years.

요즘 신문 광고를 보면 자주 볼 수 있는 광고 형식이 있다. 그것은 00 마케팅 대상, 00 신문 선정 올해의 최고 히트 제품, 스포츠 신문 선정 올해의 10대 제품, 00 협회 컨설팅 선정 고객 만족도 최우수 제품, 00부 선정 올해의 벤처 기업 등 정부나 언론 기관, 그리고 비영리 성격의 제 3 기관에서의 수상 사실을 광고 소재로 활용하는 수상(award winning) 광고이다. 그 동안 선행 연구에서는 브랜드, 가격, 제품 외관, 제조회사 정보, 보증 등을 품질을 나타내는 단서로서 주목해 왔으나 제 3 기관의 추천의 효과에 대해서는 연구가 비교적 적은 편이다. 이번 연구는 기존 연구에서 다루지 않았던 제 3 기관의 추천을 수상 맥락(award context)에서 확인해 봄으로써 제 3 기관 추천과 관련된 연구 범위를 다양화했다는데 의의를 둘 수 있다. 지금까지 소비자 관점에서 제 3 기관의 추천 효과를 조절하는 변수들에 대한 연구들은 진행되었으나 기업 관점에서 마케팅 변수들의 조절 효과를 검토한 연구는 없다고 판단하였다. 따라서 본 연구는 제 3 기관의 수상 정보가 주는 효과를 이론적 범주에서 설명하고, 실험을 통해 이러한 과정에서 마케팅 변수들의 조절 효과를 확인하였다. 연구 결과 제 3 기관의 수상 정보는 소비자들의 제품 구입 의도를 높이는데 긍정적인 역할을 하는 것으로 나타났고 제품 타입, 판매 채널과 같은 마케팅 변수들이 이 과정을 조절하고 있는 것으로 나타났다. 그리고 외재적 단서 중 하나인 지각된 가격은 제품 타입에 따라 역할이 상이했는데 경험재의 경우에는 제 3 기관의 수상 정보와 독립적으로 구매 의도에 영향을 주었고 탐색재의 경우에는 소비자 구매 의도에 큰 영향을 주지 않은 것으로 나타났다. 이번 연구 결과로부터 마케팅 실무에 활용할 수 있는 몇 가지 시사점들을 추론해 보면 가격이 비교적 고가이고 고객과의 직접 접촉을 통해 판매가 가능하며 소비자들이 내재적 단서를 통해 품질을 평가하기 어려운 경험재의 경우 제 3 기관의 수상 형태의 추천 효과가 극대화될 수 있는 조건이라고 말할 수 있다.

This study aims to configure what dimensions make up for smart phone after service quality, and how this service quality affects customer satisfaction and customer loyalty. Smart phone market is a market of the device leading the digital convergence as well as positioning itself as one of the national growth driving industry. To survive in this matured market, companies should have to respond actively to radical changes and customers needs in the so-called Smart Revolution environment. Lately, however, the smart phone market is prospected to move from growth phase to mature phase by the scholars. In order to proactively respond to the change in such market condition, companies need to provide absolute advantage in customer loyalty over their competitors by revolutionizing the after-sales service quality. Qualified A/S will lead to service satisfaction and achieve customer loyalty. The empirical analysis results obtained through A/S quality are as follows : First, human quality (attitude, expertise, problem-solvability), environment quality (handling agility, convenience, comfort), service policy quality (quality guarantee, additional service operation) are dimensions that make up for A/S quality. Second, A/S quality dimension showed a significant positive influence on service satisfaction and A/S satisfaction showed a positive influence on customer loyalty as well. Based on this empirical study, we propose some implications for A/S quality improvement. First, human quality dimension has relatively higher influence on A/S satisfaction in case of free A/S, so companies need to solve the product problem completely when consumer's first visit by continual employee education. Second, in case of paid A/S, the service policy quality-especially A/S Warranty period- has higher influence on A/S satisfaction.

본 본문에서는 LPG 용기용 가스밸브의 O-링과 밸브패킹의 밀봉결함과 크랙에 관련된 실험적 연구를 수행하고자 한다. LP 가스의 누출을 방지하기 위해 사용하는 O-링은 LPG 밸브의 밀봉 안전성을 확보하는 핵심부품으로 대단히 중요하다. 밸브패킹은 LPG 연료의 공급과 충전을 하는데, 가스 공급구를 열고 닫는 중요한 역할을 담당한다. 이들 두개의 밀봉부품에 대한 성능은 밸브의 누설 안전성과 장수명에 밀접한 관련이 있다. 연구결과에 의하면, O-링의 대부분은 파티션 부근의 결합불량과 과도한 압축률로 인해 원주방향으로 크랙이 발생하는 것으로 분석되었다. 그 이외의 결함으로 거론된 경우는 LP가스의 과도한 가스압력으로 인한 압출현상의 발생은 압출크랙을 일으키는 원인으로 작용하고 있다. 따라서 본 논문에서는 가스밸브의 누설 안전성을 확보하고 수명을 연장하기 위해 O-링과 밸브패킹에 대한 엄격한 품질관리와 인증제도의 도입을 권장하고자 한다. 결국에는 LPG용기용 밸브의 품질과 안전성 확보를 위해 밀봉장치에 대한 품질안전 보증제도를 도입해야 밸브를 오랫동안 사용할 수 있을 것이다.
