This study examined the relations among CRM activities of cosmetic companies, relationship benefits, relationship commitment, and brand switching reduction intention. The participants consisted of 399 women over the age of 20. The results of this study were as follows: First, CRM activities were perceived as a concept of sub-components, and the customers recognized the relationship benefits and commitments. Second, CRM activities did not make a positive effect on brand switching reduction intention. Third, CRM activities had a positive influence on relationship benefits, and the relationship benefit affected the brand switching reduction intention positively. Fourth, CRM activities created a positive effect on relationship commitment, and also the relationship commitment had a positive effect on brand switching reduction intention. Lastly, relationship benefits had a positive effect on relationship commitment and it was precedent variables.

교정용 스크류의 적절한 식립 토오크는 스크류와 골과의 경계에 적절히 작용하여 실패를 최소화 할 수 있는데, 너무 낮은 식립 토오크는 안정성이 없으며 반면에 너무 강한 식립 토오크는 열, 기계적 손상으로 골 괴사를 야기할 수도 있다. 본 연구에는 임상적으로 스크류의 길이와 직경 및 형태 등을 달리하여 식립 토오크를 측정해서 스크류의 각 부분에 대한 세분화된 토오크의 변화를 분석하고자 하였다. 연구결과 1.5 mm 두께의 인공피질골 블록에서 cylindrical type 스크류와 taper type 스크류 두 형태 모두에서 스크류 길이가 길수록 최대 식립 토오크 값도 함께 증가하였다. 특히 cylindrical type 스크류에서 길이에 따른 토오크 변화에 대해 통계적으로 유의한 차이가 관찰되었다 (p<0.05). 미니스크류의 연속적인 식립 토오크 분석 결과 cylindrical type 스크류는 연속적인 그래프 형태를 보이면서 불완전 나사부에서 식립 토오크가 크게 증가하였으며, taper type 스크류는 나사선의 마지막 경사진 부분에서 식립 토오크가 크게 증가하였다. 외경이 커질수록 최대 식립 토오크 값은 증가하였는데, 통계적으로 유의한 차이를 보였다 (p<0.05). 형태와 외경, 길이는 모두 토오크 값에 유의한 영향을 미치는데, 식립 토오크에 가장 큰 영향을 미치는 것은 외경, 형태, 길이 순서였다. 본 연구 결과 스크류의 식립 토오크에 가장 큰 영향을 미치는 것은 스크류의 외경이며 각각의 해부학적 구조물에 대한 피질골의 두께를 고려하여 적합한 스크류의 두께 및 나사산의 형태를 선택하는 것이 스크류의 초기 고정력을 얻는데 유리하다고 판단된다. Objective: The purpose of this study was to measure the insertion torque of orthodontic miniscrews regarding changes in their shape, diameter, and length. Methods: Torque values were measured during continuous insertion of the miniscrews into solid rigid polyurethane foam, using a torque tester of driving motor type with a regular speed of 3 rpm. Orthodontic miniscrews (Biomaterials Korea, Seoul, Korea) of cylindrical type and taper type were used. Results: Increasing the length and diameter of the miniscrews increased the maximum insertion torque value in both cylindrical and taper type screws. Insertion torque was increased at the incomplete head of the cylindrical type screw, and at the tapered part of the taper type screw. The insertion torque value of miniscrews was influenced most by diameter, then shape and length. As a result, it was shown that the diameter of the screw had the most influence on insertion torque, and the taper type screw had a higher torque value than the cylindrical type screw. Conclusion: Therefore, a large diameter or taper type screw are adequate for areas of thin cortical bone with a large interdental space, and a small diameter or cylindrical type screw are adequate in the mandibular molar area or the midpalatal area having thick cortical bone.

The purpose of this study was to develop service quality dimension beauty parolrs in Seoul area. The subject consisted of 545 adults with ages ranged between 20 and 30 who had evaluated service quality dimension on one of the three different types of beauty parlors in seoul. The beauty parlors were classify into three types. Type I is franchised one, type Ⅱ is located in center of city type Ⅲ is close to consumer`s residence area. The result was as follows : 1. Four dimensions of the service quality of the beauty parlor were physical aspects(tangibles·accessibility·cleanness), employee aspects(empathy·capability), policy aspects of beauty parlor(management·reputation·credit card), the skill of the hair stylist. 2. To predict comsumer satisfaction, service quality dimensions were as follows : In franchised beauty parlor, the employee aspects(empathy), the policy aspect (reputation), the skill of the hair stylist were should be considered. In beauty parlor in downtown area, physical aspects(accesibility), the employee aspects(capability), the policy aspects (reputation), the skill of the hair stylist were should be considered. And the beauty parlor in residence area, the employee aspects (empathy), the policy aspects(reputation) were should be considered.

The Acanthopanax genus belonging to the Araliaceae family is widely used as a traditional medicine having tonic and sedative effects. For the quality control of Acanthopanacis Cortex, lignan compound, acanthoside D, was isolated from the MeOH extract of Acanthopanax sessiliforum Seeman. (Araliaceae) and identified by the spectroscopic analysis. A quantitative analysis of acanthoside D using HPLC method showed that the average contents were $0.081{\pm}0.058%$ in 39 samples collected throughout the regions of Korea.

안산지역의 하천 침전 토양에서 식물병원성진균에 대한 길항능력이 좋은 세균을 분리하였다. 이들 중 한 균주가 Rhizoctonia solani, Botrytis cenerea와 Fusarium oxysporum의 생장을 저해하는 활성을 보였다. 이 균주는 표현 형질과 분자계통학적인 특징에 의거하여 Pandoraea sp.로 동정되었다. 그리고 생육 최적 조건을 검토한 결과 tryptone과 sucrose가 각각 최적 질소원과 탄소원임을 확인할 수 있었으며, 최적 pH와 온도는 각각 pH 7.0 와 30℃임이 확인되었다. Pandoraea sp. BCNU 315가 생성하는 물질들은 column chromatography로 정제하였고 고속액체크로마토그래피(HPLC), GC-MS 그리고 핵자기공명(NMR) 장치로 구조를 분석하였다. 그 결과 한 화합물은 indole이었으며 또 다른 화합물은 cyclopentadecaheptene임이 추정되었다. 한편 Pandoraea sp. BCNU 315가 생성하는 6개의 화합물 중 나머지 4개 화합물의 자세한 구조 해석은 추후 연구를 통하여 밝혀져야 할 것이다. Bacteria that antagonize plant pathogenic fungi were isolated from the sediment soil at the Ansan industrial estate. One isolate of them showed growth inhibition of Rhizoctonia solani, Botrytis cenerea, and Fusarium oxysporum. This strain was identified as Pandoraea sp. based on phenotypic and phylogenetic characteristics and termed Pandoraea sp. BCNU 315. Tryptone as nitrogen source and sucrose as carbon source were found to be most effective for the microbial growth. In addition, the optimum temperature and pH for microbial growth were 30℃ and pH 7.0, respectively. The substances generated from Pandoraea sp. BCNU 315 were purified and analyzed by column chromatography, HPLC, GC-MS and NMR. As a result, one compound was determined to be indole, another compound was predicted as cyclopentadecaheptene. Detailed structural clarification of the all of the rest six compounds from Pandoraea sp. BCNU 315 has to be accompanied in the further studies.
