Brands have their own life cycles and exert a great influence on the marketing activities of companies. This study examines the marketing activities according to a brand life cycle and measures the scope of their performances. The research divides a fashion brand life cycle into three stages through the analysis of secondary data, and validates the causal relationship between marketing activities, brand equity, and consumer behavior according to the brand life cycle. A total of 573 responses were analyzed through a factor analysis, path analysis, and paired t-test with SPSS 12.0. The results are as follows: According to the analysis of the relationship between marketing mix and brand equity, distribution strategies are effective at the introduction/growth stage and the continuation stage. Advertisement strategies should be a main focus at the maturity stage for brand awareness. Throughout all the stages, product strategies wield the greatest influence on the brand image. Among brand equity components, the brand image has an influence on consumer behavior at every stage of the cycle while the brand awareness has no significant effect on consumer behavior. The marketing mix component that has the greatest impact on consumer behavior is product. Contrary to general expectations, price has a negative or insignificant effect on consumer behavior at every stage of the cycle. The results illustrated in this study help to understand the life cycle of fashion brands and characteristics different from consumer goods. Thus, fashion companies should identify at which stage their brands are positioned and develop different strategies to fit each stage.

Recently, the Ministry of National Defense has included embedded software for weapon systems as targets for the Defense cyber security. The Concept has been extended and evolved from the cyber security area that was previously limited to the information domain. The software is becoming increasingly important in weapon systems, and it is clear that they are subject to cyber threats. Therefore, We would like to suggest a improvement direction by diagnosing problems in terms of cyber security of the weapon systems for the life cycle. In order to improve cyber security of weapon systems, comprehensive policy including the weapon embedded software management should be established and the involved stakeholder should be participated in the activities.

The purpose of this study is to investigate three issues. First, we investigated four control mechanisms that might increase the franchisee's perception of franchiser commitment: a franchiser's TSIs, relational norms, monitoring, and qualification programs. Second, we proposed that appropriateness and efficacy of these control mechanisms in fostering franchiser commitment might be changed over the relationship life cycle. Third, we examined how bureaucracy and levels of franchiser's commitment related to relationship satisfaction. Through empirical analysis, research results indicate that a franchiser's TSIs and relational norms are positively associated with the franchisee's perception of franchiser commitment. In detail, what increase franchisee's perception of franchiser commitment in short-term relationship are franchiser's TSIs but relational norms are more important in the long-term relationship. In addition, the results show that franchisee's perception of franchiser commitment, participation and formalization are positively related to relationship satisfaction.

GTD111 DS of nickel base superalloy has been used for gas turbine blades. In this study, low cycle fatigue test was conducted on the GTD111 DS alloy by setting conditions similar to the real operating environment. The low cycle fatigue tests were conducted at room temperature, $760^{\circ}C$, $870^{\circ}C$, and various strain amplitudes. Test results showed that fatigue life decreased with increasing total strain amplitude. Cyclic hardening response was observed at room temperature and $760^{\circ}C$; however, tests conducted at $870^{\circ}C$ showed cyclic softening response. Stress relaxation was observed at $870^{\circ}C$ because creep effects occurred from holding time. A relationship between fatigue life and total strain range was obtained from the Coffin-Manson method. The fratography using a SEM was carried out at the crack initiation and propagation regions.

최근 제조업체들은 치열한 서비스 경쟁을 벌이고 있지만, 제조업체를 대상으로 한 서비스 연구는 부족하다. 본 연구는 제조업체 서비스가 고객과 기업 간의 정보 교류의 장이 될 수 있다는 관점에서, 제품 판매 이후 고객과의 관계 속에 일어나는 모든 활동을 '판매 후 시장활동'이라고 정의하고 활동 유형 분류하였다. 가전업체를 대상으로 하여 기업의 조직특성과 제품특성이 판매 후 시장활동에 미치는 영향을 살펴보았다. 연구 결과에 의하면 조직특성에서는 부서간 협력이, 제품특성에서는 제품수명주기가 유의한 영향을 미치는 것으로 나타났다.

InGaN/GaN로 제작된 Blue chip의 파장에 따른 백색 LED의 성능 저하를 전기적, 광학적 특성을 고려하여 조사하였다. 4가지 파장으로 제작된 백색 LED Sample들은 60 mA, 75 mA, 90 mA의 주입 전류로 장 시간동안 스트레스를 주었다. 또한 형광체가 없는 상태와 있는 상태를 구분하여 패키지의 감쇠 특성을 확인하였다. Blue 피크 파장 437 nm, 주입전류 90 mA, 형광체가 있는 상태와 형광체가 없는 상태에서 패키지의 출력 광세기는 각각 20%, 36%까지 감소하였다. 이는 Blue Chip에서 출력되는 단파장이 페키지 몰드의 노화(황변)현상에 직접적인 영향을 주기 때문이다. 전기적 특성은 Blue chip의 파장영역에 의존하지 않고, 스트레스 시간에 따른 LED내부 저항이 커지는 현상을 확인하였다. 따라서 InGaN/GaN로 제작된 백색 LED의 장 수명을 얻기 위해서는 Blue chip의 출력 파장 영역과 페키지 몰드 재료 특성의 신뢰성 관계가 중요하다.

South Korea's OF cable is reaching its expected design life of 30 years, and as a result, the risk of failure is increasing. Therefore, it is necessary to diagnose the long-term operating OF cables through accurate diagnosis at the right time to prevent the failure. Currently, the KEPCO periodically conducts DGA. However, the gas found in DGA is caused by oil deterioration as well as insulation paper. Therefore, the analysis of the degree of polymerization and furan compounds which is an evaluation of insulation paper considered to be the life of OF cables is required. In addition, the results of the evaluation of deterioration of insulation paper need to be checked for correlation with the results of DGA. In this study, DGA carried out through GC, the degree of polymerization was analyzed using an automatic viscometer, and HPLC was used to detect the furan compounds. In addition, the obtained results were applied to the SVM technique, which was recently introduced to determine abnormalities in OF cable. And the results which were accurate and reliable were obtained.

Due to the development in industrial technology, changes in consumer behavior and aggravating competition within the industry, it is growing only harder every day to build up a strong brand power. Besides, a brand is supposed to age as time goes by, following a brand life cycle, as it is not a solid, immutable asset but something of a living creature. Therefore, self-renovation and revitalization efforts are needed, in order to incessantly confirm the self existence through the relationship with the consumer. In sum, revitalization operation is needed to renew a brand that has grown trite in the passage of time or due to the change in market condition, so as to bring it back anew to the consumers. This study did not stop at measuring the effect of a design renewal as a short-term assignment, but focused on the long-term brand management following the brand life cycle and aimed to define the effective timing and method of revitalization by comprehending the analysis results of consumer consciousness by analyzing the successful cases of brand revitalization and selecting the research analysis targets. As a result, this study proved that a properly-timed brand revitalization efforts in order to cope in advance with predictable changes in environment, can significantly prevent any drop of brand equity from occurring and then extend the brand life cycle. Also, this study could find that a brand revitalization is not a mere concept of a strategy for a short-term sales increase, but should be a long-term strategy to manage a brand, which must be practiced continuously in the time when the brand life cycle curve starts to fall. This research could also confirm that a superficial design renewal, which changes only the packaging of a brand, peformed in short-term haste, is not of help at all.

This research aimed to do an empirical study, by comparing the relationships of service quality, customer satisfaction and customer loyalty in mobile telecommunications between Korea and China which possess different growth phases. For this purpose, six factors in service quality, customer satisfaction and customer loyalty have been under a regression analysis to verify the causal relationship. The key findings of this study are as follows. Both Korea and China showed the causal relationship between customer satisfaction and customer loyalty; the service support which applies as the core services, have been found to be the most important factors in customer satisfaction and customer loyalty. And this study has been able to establish strategic views on reinforcing customer bases in mobile telecommunication service markets in both countries.
