모험관광 참가와 여가몰입, 여가만족, 및 생활만족의 관계
권현재(Hyun-Jae Kwon),박근수(Keun-Soo Park) 한국콘텐츠학회 2009 한국콘텐츠학회논문지 Vol.9 No.1
여가활동 참가자들의 특성을 파악하고, 여가활동 형태에 따른 참가만족과 생활만족간의 관계를 규명한 연구들은 최근 증가하고 있으나, 모험관광의 여가만족도 및 생활만족도에 미치는 효과에 대한 연구는 미약한 실정이다. 이에 따라 본 연구에서는 모험관광 참여자의 참여형태, 여가몰입, 여가만족도 및 생활만족 도간의 영향관계를 구명하여 건전한 여가활동이 정착될 수 있도록 하는 데 이론적 기초를 제공하고자 한다. The purpose of this study is to identify characteristics of leisure activity participants and to investigate the correlation between leisure satisfaction and life satisfaction according to the type of leisure activities. This study provide the theoretical and strategic insight to the marketers and policy makers for developing sound leisure activities.

Purpose: To verify the anti-microbiotic activity and to develop eco-friendly surface disinfectants using the Opuntia ficus-indica extract. Methods: The stem and fruits of the Opuntia cultivated in Jeju Island were extracted with hot water, 70% EtOH and 100% MeOH, respectively. To examine the antimicrobial activity of the extracts, gram positive bacteria (Bacillus subtilis, Staphylococcus aureus), gram negative bacteria (Escherichia coli, Salmonella typhimurium), yeast (Candida albicans), mold (Aspergillus flavus) and antibiotic resistant bacteria (E. coli, S. aureus) were measured to form a clear zone. Results: The antibacterial activity of the fruit extract was higher than that of the stem extract, and the antibacterial activity of the 100% MeOH (FM) extract and the 70% EtOH (FE) extract of the palm cactus fruit was suitable for the surface disinfectant overall, and clear-zone formed even at relatively low concentrations (250 mg/mL). The FM and FE have antibacterial activity against various bacteria, therefore they can be used as disinfectants. Conclusion: The antimicrobial activity of Opuntia ficus-indica extract from Jeju Island by stem and fruit was determined at relatively low concentrations (250 mg/mL). The Opuntia ficus-indica extract will be useful for surface disinfectants dissolving the patients’ bath, oral gargling, and powdered powder in water or ethanol in appropriate concentrations.
관광축제 브랜드개성 요인의 탐색과 태도와 충성도에 미치는 영향
임명재(Myoung-Jae Lim),권현재(Hyun-Jae Kwon) 한국콘텐츠학회 2010 한국콘텐츠학회논문지 Vol.10 No.12
관광축제분야는 지속적인 성장을 거듭하고, 관련 시장의 경쟁이 치열해지고 있다. 이와 같은 축제시장에서 차별화된 경쟁력 확보를 위한 브랜드개성은 중요한 관심의 대상이 되고 있다. 따라서 본 연구에서는 관광축제 브랜드개성 구성차원의 도출과 더불어 브랜드개성이 축제에 미치는 영향을 검토하였다. 검토결과 관광축제 브랜드개성은 유능/세련, 흥미, 성실과 같은 3가지 차원으로 구성되는 것으로 나타났다. 브랜드 개성요인 중 흥미, 성실요인은 축제태도에 영향을 미치고, 유능/세련, 흥미요인은 충성도에 영향을 미치는 것으로 나타났다. 따라서 축제의 경쟁력 확보를 위해서는 축제 브랜드개성에 관심을 갖고 축제의 차별화된 경쟁력 확보를 위한 노력을 기울여야 할 것이다. The area of tourism events is constantly growing. The competition in the tourism market is also getting so fierce that improving competitiveness through specialized brand personality is necessary to survive. So, this study derives the components of tourism events and clarifies their influences. The research shows that the brand personality of tourism events consists of three factors such as competence/sophistication, excitement and sincerity. As a result of the analysis, excitement and sincerity have impact on the event attitude while competence/sophistication and excitement on royalty.
질산태 질소 정량을 위한 환원 증류법에서 Devarda’s Alloy의 입자크기 및 함량이 미치는 영향

We analyzed the particle size distributions of three commercially available Devarda’s alloy (DA) products, tested the nitrate recoveries of each particle size category, and examined the amounts of DA required for 100% recovery by varying NO3−N concentration from 0.5 to 10 mg. We observed that use of DA coarser than 200 mesh resulted in poor analytical recovery (< 80%). While the tested alloys were considered to be fine enough (>90% of the particles were less than 100 mesh), the recovery dramatically declined from 80% to 10% in a high concentration range (4 to 10 mg N). Satisfactory recovery was obtained by increasing the amount of finer DA (less than 300 or 450 mesh). However, there was no quantitative relationship between the amount of fine DA and nitrate recovered. Generally, the amount of nitrate reduced per unit DA decreased as the recovery efficiency declined. These results suggest that a sufficient amount of DA must be determined based on particle size distribution, and that treatment of at least two levels of DA and comparison of the subsequent change in nitrate recovery is required for soils containing high levels of nitrate. In addition, further studies are encouraged to account for the observed stoichiometric dis-equivalence of recovered nitrate N per unit mass of DA.

This study examined the usability of the web site design, focusing on the cognitive characteristics of the internet. Specifically, we conducted two major non-experimental usability testing methods on the tourist business web sites with various purposes. In research 1, we used an on-line questionnaire method on 12 tourist business web sites. As a result, several critical usability features and factors were identified. In research 2, we carried out a heuristic evaluation method to identify more specific usability problems. The result of research 2 suggests that the heuristic evaluation method reveals more specific problems of the web site design than the questionnaire method.
