Domestic apparel products labeled as ‘Made in Korea’ in the Chinese market are recognized as a high quality products due to the influence of the Korean Wave (Intergen Consulting Group, 2007). This study analyzes the patterns and order arrangement types of a fashion brand company commissioned to produce apparel in Seoul, Korea in order to rebuild a network of small sewing factories scattered in Korea, reorganize operations, and to find the possibility of regenerating the Korean sewing industry by establishing contact points with domestic sewing factories. We surveyed 100 apparel brand companies in Seoul listed in the 2014/2015 Korea Fashion Brand Annual (Apparel News, 2014) and conducted a questionnaire survey on the company’s general management status, type of fabric materials dealt with, and major contact points and methods of production handling. The frequency analysis indicated that the main production material with cloth type was woven fabric with ladies’ clothes. The Planning MD team has the highest rate of ordering production with delivery method to the production factory after purchasing fabric and trims. Most respondents answered that they would select a production factory based on recommendations from acquaintances. This was due to a lack of no objective indicator provided by the sewing factory at present and the absence of objectively proceeded communication with brand companies. In this study, we analyze various conditions and measurements for production arrangements from a fashion brand company to revitalize sewing factories in Korea.

Purpose: To investigate the effect of amniotic membrane extract (AME) on the survival, nitric oxide production by cultured human Tenon`s capsule fibroblasts (HTCF) and contraction of collagen gels. Methods: After exposure to 5~20 ?g/ml AME for 5 days, the survival and nitrite production of the primarily cultured HTCF were assessed with MTT and Griess assays respectively. Acridine orange/Hoechst 33342 double staining and flow cytometric analysis using FITC-Annexin/propidium iodide double staining were done to evaluate AME-induced apoptosis of HTCF. The effect of AME on the contraction of collagen gels cultured with fibroblast was also evaluated. Results: AME decreased cellular survival in a dose-dependent manner and did not affect the production of nitric oxide. AME caused apoptotic death of HTCF in a dose-dependent manner and caused necrosis at high concentration (20 ?g/ml). AME did not affect on the contraction of collagen gel. Conclusions: AME decreased cellular survival of HTCF by apoptosis and did not affect the contraction of collagen gels. Thus AME could modulate conjunctival wound healing by suppressing the cellular survival and activity of HTCF.

이 실험은 이식재로 Deproteinated Bovine Bone Powder (DBBP)를 사용하였을 때와 골 이식재를 사용하지 않고 단순히 Absorbable Gelatin Sponge(AGS)만을 사용하였을 때의 BMP4와 BMP6의 상대적인 발현량을 real-time RT-PCR을 이용하여 비교해 보기 위한 것으로 다음과 같은 결과를 얻었다. 1. BMP4의 경우 처음 1일째와 3일째의 경우 DBBP군과 AGS군 모두 일정하게 증가하였으나 5일째 AGS군에서 감소하다가 7일째 다시 증가하였으며 9일째 다시 감소하였다. DBBP군에서는 7일까지 계속하여 증가하다가 9일째 감소하였다. DBBP군이 AGS군에 비해 발현의 양이 많은 경우가 많았지만 유의성은 없었다 (p>0.05). 2 BMP6의 경우 처음 1일째와 3일째의 경우 DBBP군과 AGS군 모두 일정하게 증가하였으나 5일째 AGS군에서 감소하다가 7일째 다시 증가하였으며 9일째 다시 감소하였다. DBBP군에서는 7일까지 계속하여 증가하다가 9일째 감소하였다. AGS군이 DBBP군에 비해 발현의 양이 많은 경우가 많았지만 유의성은 없었다 (p>0.05). 3. 두 군간에 동일시기에 BMP발현이 유의할 만한 차이를 보이지 않는 것은 DBBP와 AGS 모두 space retainer로서 작용을 하여 혈병중의 BMP발현의 양상이 비슷하기 때문으로 여겨진다. 4. 따라서 DBBP가 AGS에 비해 초기 골재생에 크게 유리한 점은 없는 것으로 여겨지며 초기 골 형성에서 BMP의 발현은 이식재의 종류가 아니라 물리적인 carrier로서의 작용이 더 중요한 것으로 여겨진다. The most important factor for successful implantation is osseointegration between the implant and bone. The expression of bone morphogenetic proteins (BMPs) inducing bone formation would differ after maxillary sinus elevation. And within the same graft material. the expression of BMPs would change with time after graft. The aim of this study was to compare the relative expressions of BMP4 and BMP6 using real-time RT-PCR when maxillary sinus elevation was performed using deproteinated bovine bone powder (DBBP) as the graft material or absorbable gelatin sponge (AGS) as the filler without any graft material. Fifteen rabbits, each weighing between 3.0 to 3.5 Kg, were divided randomly into 5 groups of 3 animals each based on their time of sacrifice 0, 3, 5, 7 and 9 days). After exposure of the maxillary sinus bilaterally, bone graft was performed in the right maxillary sinus using DBBP ($BBP^{(R)}$ Oct Inc., Cheonan, Korea) and only AGS ($Gelfoam^{(R)}$ Pharmacia & Upjohn Company, Kalamazoo, MI, U.S.A) was placed into the left without any graft material. Each group of rabbits was sacrificed at 1, 3, 5, 7, or 9 days after operation and all specimens were harvested. And the following results were obtained using real-time RT-PCR from isolated total RNA of the samples. 1. The expression of BMP4 increased at postoperative 1 and 3 days in both DBBP group and AGS group. In AGS group. it decreased at postoperative 5 days. increased again at postoperative 7 days, and decreased at postoperative 9 days. In DBBP group, it increased until postoperative 7 days and decreased at postoperative 9 days. Although the expression of BMP4 was higher in DBBP group compared with AGS group, it was not statistically significant (p>0.05). 2. The expression of BMP6 increased at postoperative 1 and 3 days in both DBBP group and AGS group. In AGS group, it decreased at postoperative 5 days, increased again at postoperative 7 days, and decreased at postoperative 9 days. In DBBP group, it increased until postoperative 7 days and decreased at postoperative 9 days. Although the expression of BMP6 was higher in AGS group compared with DBBP group, it was not statistically significant (p>0.05). 3. There was no statistically significant difference in BMP expression in both groups during same period of time. It' s probably because DBBP and AGS both functioned as a space retainer so that the BMP expression in blood clot seemed to be similar. 4. Thus, DBBP would not offer many benefits for early bone regeneration compared with AGS. The expression of BMP in early bone formation seems to be more influenced by physical carrier rather than the graft type.

Introduction: Dental implants are used routinely with high success rates in generally healthy individuals. By contrast, their use in patients with diabetes mellitus is controversial because altered bone healing around implants has been reported. This study examined the bone healing response around titanium implants placed immediately in rats with controlled and uncontrolled diabetes. Materials and Methods: Twenty rats were divided into the control, insulin-treated and diabetic groups. The rats received streptozotocin (60 mg/kg) to induce diabetes; animals in the insulin-treated group also received three units of subcutaneous slow-release insulin. A titanium implant (1.2×3 mm) was placed in the extraction socket of the maxillary first molar and bone block was harvested at 1, 2 and 4 weeks. Results: Bone formation around the implants was consistently (from 1 to 4 week post-implantation) slower for the diabetic group than the control and insulin-treated group. Bone morphogenesis in the diabetic rats was characterized by fragmented bone tissues and extensive soft tissue intervention. Conclusion: The immediate placement of titanium implants in the maxilla of diabetic rats led to an unwanted bone healing response. These results suggest that immediate implant insertion in patients with poorly controlled diabetes might be contraindicated.

The new type of orthodontic mini-implant named C-implant can be an effective alternative to conventional one-component mini-implant in the intermaxillary fixation (IMF) cases because of its particular design. The small size, two-part design, efficiency, and low cost of the C-implant make it applicable to various types of IMF cases easily such as fracture reduction and orthognathic surgery. The two part design resists highly to the fracture or deformation during implantation and removal. The long span head allows the patient to easily attach intermaxillary elastics, so that the patient can apply intermaxillary elastics for traction easily. Through this article, we tried to show the possibility of this appliance as a good adjunct for the IMF screw.

Chondroblastoma was introduced as a rare benign cartilaginous neoplasm by Codman in 1931. It described by Jaffe and Lichtenstein in 1942 as a benign cartilaginous neoplasm that represents less than 1% of all primary bone tumor. It commonly arises in the epiphysis of long bone but, it occurs very rare in temporal area. Sometimes, microscopic identification of chondroblastoma and giant cell granuloma is difficult. An immunohistochemical studies was performed for S-100 protein which is useful in arriving at the correct diagnosis. Treatment modalities are total curettage, en-bloc excision, irradiation, and radiation combined with surgical excision. But radiation therapy was controversial. We describe a case of chondroblastoma which was arisen in the right temporal area and the recurrence that was treated by surgical excision and radiation therapy with review of literature.
