The purpose of this study is to analyze the characteristics of two local festivals, already recognized as a successful regional cultural festival, over a period of time to apply the product life cycle theory. As a result of the analysis of the two festivals, in introduction stage, the festival organizers have focused mainly on settling down the festival's core programs and raising awareness on the subject of the festival for the stimulation for basic demands. Second, for maintaining increasing demands, the qualitative improvement of the core program, the development of new programs and the expansion of the programs for the visitors' convenience and safety were focused on. In addition, strategies for promoting awareness of the festival had modified the strategy to promote on the contents and programs of the festival, as well as public relations strategy, not only domestic but also the foreign countries, was established and fulfilled. Lastly, in maturity stage, to overcome declining the number of visitors and economic effect both festivals have showed providing sophisticated programs for the visitors' convenience and safety, improving service quality through the development of the existing programs, providing economic benefits such as admission cuts or giving gift certificates and expanding number of foreign visitors with strengthening the promotion that was implemented in growth stage and enhancing the better image of the festival through the social contribution. Therefore, strategies for the each stage mentioned above present the significant policy implications for festival organizers who were planning to establish a new festival or implementing a festival with experiencing the tepid growth.

Ticks, blood-sucking ectoparasites, spread diseases to humans and animals. Haemaphysalis longicornis is a significant vector for tick-borne diseases in medical and veterinary contexts. Identifying protective antigens in H. longicornis for an anti-tick vaccine is a key tick control strategy. Enolase, a multifunctional protein, significantly converts D-2-phosphoglycerate and phosphoenolpyruvate in glycolysis and gluconeogenesis in cell cytoplasm. This study cloned a complete open reading frame (ORF) of enolase from the H. longicornis tick and characterized its transcriptional and silencing effect. We amplified the full-length cDNA of the enolase gene using rapid amplification of cDNA ends. The complete cDNA, with an ORF of 1,297 nucleotides, encoded a 432-amino acid polypeptide. Enolase of the Jeju strain H. longicornis exhibited the highest sequence similarity with H. flava (98%), followed by Dermacentor silvarum (82%). The enolase motifs identified included N-terminal and C-terminal regions, magnesium binding sites, and several phosphorylation sites. Reverse transcription-polymerase chain reaction (RT-PCR) analysis indicated that enolase mRNA transcripts were expressed across all developmental stages of ticks and organs such as salivary gland and midgut. RT-PCR showed higher transcript levels in syn-ganglia, suggesting that synganglion nerves influence enolase's role in tick salivary glands. We injected enolase double-stranded RNA into adult unfed female ticks, after which they were subsequently fed with normal unfed males until they spontaneously dropped off. RNA interference significantly (P<0.05) reduced feeding and reproduction, along with abnormalities in eggs (no embryos) and hatching. These findings suggest enolase is a promising target for future tick control strategies.

This paper discusses decommissioning procedure requirements management using requirement engineering to systematically manage the technical requirements and criteria that are required in decontamination and decommissioning activities, and the regulatory requirements that should be complied with in a decommissioning strategy for research reactors and nuclear power plants. A schema was designed to establish the traceability and change management related to the linkage between the regulatory requirements and technical criteria after classifying the procedures into four groups during the full life-cycle of the decommissioning. The results confirmed that the designed schema was successfully traced in accordance with the regulatory requirements and technical criteria required by various fields in terms of decontamination and decommissioning activities. In addition, the changes before and after the revision of the Nuclear Safety Act were also determined. The dismantling procedure requirement management system secured through this study is expected to be a useful tool in the integrated management of radioactive waste, as well as in the dismantling of research reactor and nuclear facilities.

Product liability (PL), which began enforcement in 2002, refers to the legal responsibility of the manufacturers or sellers (wholesales or retailers) for the property damage or bodily harm caused by their product. With a strong enforcement of the Product Liability (PL) Act, companies are required to structure and operate a response system to defend or prevent product accidents efficiently, but small and medium enterprises (SMEs) are unable to respond more aggressively due to limitation of management resources. In this manner, it is important to develop response strategies for SMEs to efficiently cope with the PL Act. In this paper, the PEST (Political, Economic, Social, and Technological) analysis is performed to reveal the impact of the PL Act on SMEs in macro-economic point of view. To formulate SME's PL response strategy, SWOT analysis is performed to categorize each factors from PEST analysis and AHP is applied to identify the intensities of SWOT factors. The prioritized SWOT factor, results of PEST-SWOT-AHP analysis, are used to formulate SME's PL response strategies. The study results are briefly summarized as follows. To reduce product defects, it is necessary for SMEs to formulate PL response strategies for each phase of the product life cycle by continuously collecting and analyzing PL cases in the same industry or for similar products. In addition, SMEs should invest more technological effort to ensure product safety. Further, SMEs should spread PL awareness to all staff members by training internal PL experts. Moreover, a SME should enroll in PL insurance and spread this information to its customers so that they become aware that the company is proactively conforming to the PL law.

This study attempted to identify differences in Korean food consumption behaviors between groups of Japanese consumers segmented in accordance to their food-related lifestyles. This study was performed to provide Korean food service companies basic information to implement a strategy for the globalization of Korean food. As a result of the empirical analysis, the food-related lifestyles of Japanese consumers were deduced to the following four factors: "health and safetyoriented lifestyle", "palate and safety-oriented lifestyle", "economic efficiency-oriented lifestyle", and "simplicity-oriented lifestyle". Further, as a result of the cluster analysis, food-related lifestyles were classified into the following three groups: "a group highly interested in food-related life", "an economic efficiency-oriented group", and "a simplicity-oriented group". Second, there were significant differences in demographic characteristics and the characteristics of Korean food consumption behaviors between the groups. Third, also in a comparison of satisfaction with and loyalty to Korean restaurants with crucial attributes during the selection of Korean food, there were significant differences between the groups. Therefore, it is necessary to develop various Korean food products that will cater to Japanese consumers in accordance with each segmented group.

In Seoul, there are lots of skyscrapers that have above 60 stories and buildings that have more than 8 basement levels, as well as massive distribution complex region which is connected to subways, departments, malls, hotels, and exhibition halls. When an accident, such as fire and explosion, happens in these areas or structures, if we can't find where fire-fighters are, who go into the building to suppress the fire, we couldn't be sure of their safety as well as effective command. Actually, it may cause much more damage itself and restrict either fire suppression or lifesaving. To protect people's life and properties as much as possible, this study will show the method to construct system of disaster-management supports with effective operation of fire force and scientific fire strategy in the scene by using Ubiquitous technique to enormous disasters.
