연구장비는 혁신체제를 구성하는 과학기술 하부구조의 하나로, 혁신 주체들이 이를 활용해 혁신 성과를 창출해낼 수 있도록 접근성이 보장되고 개선될 필요가 있다. 따라서 연구장비 사용자들의 만족 패턴을 분석하고, 서비스 개선을 위한 시사점을 살펴볼 필요가 있다. 이에 본 연구는 생산기술 분야 중소기업을 지원하는 K연구원의 연구장비 공동활용 서비스에 대한 사용자 만족 패턴 분석을 목적으로 하였다. 이를 위해 SERVQUAL, 즉 Service Quality 개념에 기반하여 연구장비 공동활용 서비스의 세부 품질 요소를 도출해 설문조사를 실시하였으며, 카노 모델과 잠재적 고객만족 개선 지수(PCSI)로 만족 패턴을 분석하였다. 카노 모델 분석 결과 총 17개 품질 요소 중 2개가 일원적 품질(O)이었고 나머지는 매력적 품질(A)로 나타났다. 또한 PCSI 분석 결과 O에 해당하는 요소 모두 순위가 높은 가운데, 5개 대분류 기준으로 볼 때 확신성, 반응성, 신뢰성, 공감성의 순위가 높은 반면 유형성이 최하위인 패턴도 확인하였다. 이러한 결과를 바탕으로 실무적, 학술적 시사점을 제공하였으며, 추가적으로 향후 업종별 차이에 초점을 둔 연구가 필요함을 제시하였다. Research equipment is a core element of science and technology infrastructure, and it is vital to provide and improve innovative actors access to it for superior innovation performance. Therefore, examining the satisfaction pattern of research equipment users and drawing implications for service improvement is important. This study analyzed the user satisfaction patterns of the shared research equipment service provided by K Institute, which supports small and medium-sized enterprises in production technology. The detailed quality attributes of the shared research equipment service were derived based on the SERVQUAL (Service Quality), and a survey was conducted. This research analyzed the satisfaction patterns using the Kano model and the Potential Customer Satisfaction Improvement Index (PCSI). Kano model analysis showed that out of 17 quality attributes, two were classified as One-Dimensional Quality (O), while the remainder appeared as Attractive Quality (A). Furthermore, according to the PCSI survey, all O attributes ranked high. When viewed based on the five major classifications, assurance, responsiveness, reliability, and empathy ranked high, while tangibles were identified as the lowest-ranking pattern. Based on these results, practical and academic implications were provided. Nevertheless, further research focusing on industry- or sector-specific differences is needed.

Purpose: When choosing dressing method to treat skin defect by second degree or higher burn, we have to consider method of rapid epithelization and minimization of pain during the treatment. In this study, we used biologic dressing with cultured allogenic keratinocytes for skin defect due to burn. We followed up the degree of epithelization, the degree of pain, and patient satisfaction. Methods: From June 2003 to June 2006, among the patients with skin defect due to burn, 31 cases with second degree burn(moderate to severe) were selected and biological dressing with cultured allogenic keratinocytes were done. 21 cases did not use cultured allogenic keratinocytes. Most of the patients had second degree burn. We applied cultured allogenic keratinocyte by Kaloderm. For wounds that were not deep enough to effect the dermis, escharectomy was done before applying Kaloderm. After the operation, moist wound site was maintained by dressing with saline gauze for 5-7 days. We compared the condition of the wound site before and after applying Keloderm by grading epithelization by standardized percentage scoring scale(1-5), and degree of pain and patient satisfaction by visual analogue scale(0-10).

Tel: 053)650-4578/Fax: 053)650-4584/E-mail: 21csue@hanmail.net Results: When cultured allogenic keratinocytes were applied for the same period of time, the mean score of epithelization were 3.29±0.529(mean±S.D.). Without the application, the mean score of epithelization were 2.86±0.655(mean±S.D.). The degree of pain was 7.71 ±1.419(mean±S.D.) and 2.35±0.950(mean±S.D.) before and after the application, respectively. The patients' satisfaction score was 6.45±0.850(mean± S.D.) and 8.45±0.961(mean±S.D.) before and after the application, respectively. Conclusion: Applying biological dressing with cultured allogenic keratinocyte to skin defect due to second degree burn showed satisfactory results in the degree of the epithelization, degree of pain and patients' satisfaction.

Purpose: Interest in the augmentation of hair growth for functional and aesthetic purpose has increased dramatically in recent years. Many hair growth products have been released, but most of these have not been proven scientifically. This study aims to measure the hair growth effect of azelaic acid and vitamin B6, which have been known as hair growth materials, in animal models. Methods: Six weeks old C57BL/6 mice were used in this study and hair of mice were removed by topical treatment. The mice were divided into five experimental groups according to the testing material such as saline (negative control), propylene glycol(vehicle control), azelaic acid, vitamin B6 and azelaic acid plus vitamin B6 in combination. Hair growth was documented photographically and histologically, and then analysed by the high quality hair analysis program system. The quantity of endocrine factors, IGF-I and TGF-β1 in the skin of mice was measured by PCR analysis. Received May 12, 2008 Revised June 16, 2008 Accepted July 14, 2008 Address Correspondence: Dae Hwan Park, M.D., Department of Plastic and Reconstructive Surgery, College of Medicine, Catholic University of Daegu, 3056-6 Daemyung 4-dong, Nam-gu, Daegu 705-718, Korea. Tel: 053) 650-4578/Fax: 053)650-4584/E-mail: dhpark@cu.ac.kr Results: The topical treatment of azelaic acid and vitamin B6 in combination for 2 weeks to dorsal skin accelerated hair regrowth more than other groups. The azelaic acid and vitamin B6-combined treatment also promoted hair follicle elongation and thickness compared to the others. Histologic studies showed increased number of basal cells in azelaic acid and vitamin B6-combined treatment. Furthermore, the azelaic acid and vitamin B6-combined group significantly increased the expression of IGF-I but decreased the expression of TGF-β1 in the skin of mice compared to other groups. Conclusion: These results suggest that azelaic acid and vitamin B6, when used together, have an additive effect and might be used as hair growth materials.

Purpose: Polypoid lesions of the gallbladder have a range of causes. A problem exists in the selection of patients for surgery. This study examined the usefulness of laparoscopic cholecystectomy, suspected risk factors and plan of patients with gallbladder polyps. Methods: This study examined 57 patients who underwent laparoscopy cholecystectomy with gallbladder polyps. All patients had been diagnosed preoperatively by ultrasound and abdominal computed tomography between October 2001 and October 2010. Preoperative radiologic diagnosis, age, gender, symptoms, size of polyps, number, concurrent gallstones and histological diagnosis of the polyps as well as the postoperative complications were reviewed retrospectively. The operation indications were polyps >10 mm, age above 55 years, symptomatic polyps, coincidence of a stone, focal thickening of gallbladder wall and detection during other operations. Results: The number of each type of polyp lesion of the gallbladder was as follows: 26 cases (45.6%) had cholesterol polyps, 2 cases (3.6%) inflammatory polyps, 1 case (1.7%) mucosal lymphoid follicles, 12 cases (21.1%) adenomatous polyps, 1 case (1.7%) adenocarcinoma. Non-neoplastic and neoplastic polyps accounted for 50.9% and 22.8%, respectively. Forty-eight cases had an accepted operative indication and underwent surgery. The nine other cases also underwent surgery. Among those with operative indications, 27.1% had neoplastic polyps. Of the patients who had non-indication operative surgery or polyps <5 mm in size, there were non neoplastic polyps in any cases. Two of the patients developed complications; wound infection (1 case), and common bile duct obstruction (1 case). Conclusion: Observation and careful surgery is necessary for patients with polyps <5 mm in size, and who do not have accepted operative indications. Laparoscopic cholecystectomy can be considered an adequate treatment for patients with accepted operative indications.

Mesotherapy is one of skin rejuvenation methods and known to be effective for anti-aging, cosmetic treatment, and improvement of obesity. Furthermore, the side effect of mesotherapy has been known to be very little, therefore, it has been used widely. Because of these reasons, complication of mesotherapy has been disregarded. A 32-year-old woman visited a private clinic for improvement of obesity. The patient had placenta injection with aminophylline, lidocaine and epinephrine on abdomen for several times and she did not have any symptoms. However, placenta injection was carried out at the last time with aminophylline, lidocaine, epinephrine and dehydrated alcohol. Four days later, abdominal partial necrosis was developed. And she was refered to our department. Wound of the abdomen had eschar formation and reddish color change. So, debridement of necrotic skin, and immediate reconstruction using flap and cosmetic abdominoplasty were done immediately, and the patient was satisfied with results. Based on various circumstances, we concluded that one of the etiologies of necrosis might be dehydrated alcohol and epinephrine effect. The standard of materials that are mixed in mesotherapy has not yet been established. In fact, the safety of additives has not yet been verified. Therefore, more studies on the standard materials and safety are needed.

[서론] 이 연구의 목적은 연령 및 체중이 건강한 성인 여성의 동적, 정적 평형 기능에 미치는 영향을 구명하는 것이었다. [방법] 이 연구에 참여한 피검자는 20대 66명(과체중군 32명, 정상체중군 34명), 30대65명(과체중군 32명, 정상체중군 33명), 40대 67명(과체중군 34명, 정상체중군 33명), 50대 74명(과체중군 38명, 정상체중군 36명), 60대 56명(과체중군 29명 정상체중군 27명)으로 총 328명을 연구대상으로 하였다. 종속변인의 검사는 Biodex medical system(balance system SD(USA)을 사용한 평형성 검사를 실시하였으며, 양발, 왼발, 오른발 지지 하에 정적 평형성 검사 및 동적 평형성 검사를 시행하였다. [결과] 전 연령층에서 과체중군이 정상체중군보다 동적 평형성 및 정적 평형성이 모두 유의하게 감소 한 것으로 나타났다. 또한 연령이 증가할수록 정적 평형성 및 동적 평형성이 모두 저하되는 경향을 보였으며 정상체중이든 과체중이든 간에 특히, 50대 이후에 평형성이 유의하게 감소하는 것으로 나타났다. [결론] 과체중은 평형성의 감소를 가져오는 요인으로 판명되었으며, 특히 50대 이후에 평형성 저하가 심하므로 낙상방지에 신경을 써야 할 것으로 보인다. [INTRODUCTION] To assess the influence of age and weight on equilibrium function in women and the comparison of the balance performance in age decade, and research of significantly decrease start age. [METHOD] Healthy individuals (n=328) were divided over-weight(BMI≥25.0 kg·m2) n=166 and normal weight(BMI≤25.0 kg·m2) n=163, adult female subjected participated in the study, and dependent variable test was performed for balance test using Biodex medical system SD(USA). And static balance and dynamic test were performed under standing on both feet, left foot, and right foot independently. [RESULTS] It appears that overweight group showed lower test scores for dynamic and static balance tests than normal weight group in all age groups. Dynamic and static balance become lower as age increases, but balance shows significant degradation over age of 50 and up regardless of weight. [CONCLUSION] Overweight becomes a factor for lower balance, and it is true that age of 50 and ups have to pay special attention to prevent from fall due to significant loss of balance at that age.
