저자들은 전자궁적축술과 요실금 수술후 요도폐색이 발생한 43세의 여자 환자에서 장기간의 간헐적 자가도뇨법과 약물요법으로 치료되지 않아, 외요도구 상방을 통한 요도 박리술을 시행하여 좋은 결과를 볼 수 있었다. 저자들의 견해로는 과거에 부인과 수술과 동반해서 시행하거나 혹은 복측으로 치골후방으로 접근하여 시행한 요실금수술이나 요도하부 슬링수술등의 방법으로 인해 요도 폐색이 발생시 외요도구 상방을 통한 요도박리술이 바람직할 것으로 사료된다.

Purpose: V.A.C. is a new concept which is closed dressing with negative pressure to promote wound healing. It has been widely used as the treatment of chronic and acute wounds such as pressure sores, burns, stasis ulcers, and other complicated wounds. However It has disadvantages such as high cost and the need of specific equipment. In this article, we described new method to overcome these disadvantages. Methods: We made newly innovated equipment with 50 cc syringe and spring to create negative pressure. From May 2006 to May 2007, we applied it to two patients with chronic wound. Results: The treatment period was 5 weeks for one case and 3 weeks for the other case. Both patients were healed completely without admission and wound healing was accelerated. During follow-ups, there were no complications. The mean cost for single dressing was 9,590 won. Conclusion: Modified portable negative therapy using newly innovated equipment could accelerate wound healing better than conventional dressing. It lowers the number of dressings, saves cost of treatment, and enables treatment as outpatient basis.

Three dogs were presented with signs of recurrence of coughing, dyspnea and difficulty of barking after endotracheal stent placement. On the basis of history taking, physical examination, laboratory tests and radiography, complications of endotracheal stent were suspected. Dog 1 had unfitted stent diameter (stent diameter is larger than tracheal diameter) and getting disentangled of proximal tracheal stent wire. Dog 2 was suspected a foreign body reaction. Dog 3 had the migration of stent caudally. Based on these cases, the veterinarian should accurately evaluate the indicated patients before endotracheal stent and has to select the appropriate stent (diameter, length and location) to prevent complications after endotracheal stent and concern the regular follow-ups to assure proper endotracheal stent placement.

This study proposes an entrepreneurship education process for fashion product start-ups through rewards-based crowdfunding. It examines issues such as: the general concept of crowdfunding and the pros and cons of rewards-based crowdfunding, the detailed curriculum plans in a chronological order for the regular class development, and the presentation of a visual plan to show the whole process. An entrepreneurship education process is developed in 13 steps: research on crowdfunding market, prototype plan, prototype production, story development, visual contents development, rewards development, project evaluation, public schedule & service setting, period setting & start funding, community management (Q&A), funding ends & deposit, complete manufacturing & start delivering, and the final information disclosure & open the next project plan. This research is intended to investigate rewards-based crowdfunding as a new paradigm of entrepreneurship and apply entrepreneurship education in fashion product development. However, it is limited to studying the Wadiz crowdfunding platform in Korea. Therefore, we propose a case study on various crowdfunding platforms in Korea, a case study on entrepreneurial curriculum application, and a follow-up study on the possibility of entry into an overseas crowdfunding platform.

The case of pseudo-aneurysm of internal maxillary artery (IMA) in oral and maxillofacial region is known to be very rare. The etiology of this case was regarded as IMA injury by radiofrequency ablation (RFA) and such incidence was not reported previously. One case of false aneurysm in the IMA was referred from local dental clinic to our department. Left facial swelling was observed with severe trismus immediately after radiofrequency procedure for masseteric nerve block in local dental clinic. Despite of medication and surgical intervention, the swelling did not subside and there was massive bleeding and pulsation on one of the follow ups. The traumatic vascular disorder was suspected and finally diagnosed with angiography and treated by embolization procedure. RFA targeting masseteric nerve or trigeminal ganglion may cause traumatic injury to adjacent anatomic structures such as IMA, resulting in pseudo-aneurysm. Clinicians must be aware of potential damages of RFA. Angiography enables the solid diagnosis for pseudo-aneurysm, and selective embolization can be optimum treatment method.

Glandular odontogenic cyst (GOC) is an intraoral cyst originated from serre remnants which has incidence of rare frequency. Only 111 cases have been reported since Gardener first introduced it in 1987. The clinical features are the following components: cortical bone thinning, locally aggressive root resorption, non-painful swelling. The following recurrences rate are 64.3% in conservative treatment, and 0% in wide excision for instance, segmental or marginal mandibulectomy. So, its prognosis is similar to that of odontogenic keratocyst and ameloblastoma. Therefore, periodic recall follow ups are essential to detect disease recurrence. Here, we will report the first case of GOC diagnosed in our department considering with references. And we share this treatment experience because these aggessive lesions may be misjudged for simple dental cyst.

Objectives: This paper aims to discuss the current situation of and future directions for health promotion practice(HPP) and research in private sectors in Korea. Methods: Publications and web-site information of public health organizations, WHO-Health Promoting Hospitals member institutes, health/medical academic societies, and professional unities were collected and reviewed. Activities of Korea Association of Health Promotion(KAHP) were described in detail considering its leading role in health examination and promotion field in Korea. Results: The most common HPPs in private sectors were health education and public health campaigns for the prevention and management of diseases. Tailored health promotion programs for lifestyle changes and longitudinal follow-ups were the routine process for managing high risk groups at KAHP. Health promotion research in private sectors have focused on identifying health problems and behavioral determinants, and planning, implementing and evaluating health promotion programs. The most serious issues in HPPs of the private sectors were limited budget and manpower along with a lack of public recognition and a system-level support. Conclusion: To promote HPPs and research in private sectors, a system for financial sustainability should be introduced. They also need scientific evidence from research. 'Borderline medicine', a discipline specialized in management of high risk borderline group, could lead HPPs to sustainable private practices.

Purpose: In this study, we investigated the effectiveness of a 12-week virtual reality exercise program using the Nintendo Wii console (Wii) in improving balance, emotion, and quality of life among patients with cognitive decline. Methods: The study included 30 patients with cognitive decline (12 female, 18 male) who were randomly assigned to an experimental (n=15) and control groups (n=15). All subjects performed a traditional cognitive rehabilitation program and the experimental group performed additional three 40-minute virtual reality based video game (Wii) sessions per week for 12 weeks. The berg balance scale (BBS) was used to assess balance abilities. The short form geriatric depression scale-Korean (GDS-K) and the Korean version of quality of life-Alzheimer's disease (KQOL-AD) scale were both used to assess life quality in patients. Statistical significance was tested within and between groups before and after treatment, using Wilcoxon signed rank and Mann-Whitney u-tests. Results: After 36 training sessions, there were significant beneficial effects of the virtual reality game exercise on balance (BBS), GDS-K, and KQOL-AD in the experimental group when compared to the control group. No significant difference was observed within the control group. Conclusion: These findings demonstrate that a virtual reality-training program could improve the outcomes in terms of balance, depression, and quality of life in patients with cognitive decline. Long-term follow-ups and further studies of more efficient virtual reality training programs are needed.

Dysplastic nevus is common and affects about 10% of the northern European-descendent population. Studies over the past several decades have identified dysplastic nevi as a risk factor for malignant melanoma. Furthermore, in rare cases, they confirmed that dysplastic nevi have progressed to melanoma. Cases in which dysplastic nevi progressed to malignant melanoma in multiple studies are not uncommon. A 35-year-old woman presented with the major symptom of multiple itchy brown nodules ($2.0cm{\times}1.3cm$) in the left cheek that had first appeared 20 years earlier. Complete excision was performed at the first visit; subsequent biopsy confirmed that they were dysplastic nevi. They recurred three times over 3 years at the same site, all of which were histologically diagnosed as dysplastic nevi. Five years after the final excision, a brownish nodule developed in the left cheek, with others at the left temporal region, right retroauricular region, and left shoulder at the same time. These lesions were histologically diagnosed as malignant melanoma. We experienced a case of malignant melanoma that occurred at the same site after three recurrences of dysplastic nevi. Although rare, the possibility of malignant melanoma should be considered in follow-ups in cases involving repeatedly recurrent dysplastic nevi.
