Purpose: Silicone gel sheet(SGS) is used for preventing and treating keloid or hypertrophic scars. Because the product is weak in tear strength and adherence, it requires several replacements, which requires high cost. As a solution for this problem, we developed a new silicone gel sheet, named as Scar Clinic, and confirmed its physical properties. Methods: Tensile strength, elongation rate, adhesiveness, and water vapor transmission rate were experimentally compared between the most commonly used SGS product and the Scar Clinic. Results: The newly developed SGS showed better results compared to the existed SGS in regards to tensile strength, elongation rate, adhesiveness, and water vapor transmission rate. Conclusion: The Scar Clinic showed higher durability and flexibility. It will be a useful product for treating scars clinically.

Post-traumatic scar deformations are common in many skin injury cases. These are usually aesthetic problems, but if these deformations impair mobility and the patient feels uncomfortable, we must resolve them. In a patient with a lateral post-traumatic scar fold in the lateral canthus that shortened the horizontal orbital fissure and created traction on eye opening, we performed modified classic Z-plasty, resulting in aesthetic and functional improvements without recurrence.

Purpose. Hypertrophic scarring and depression are the principal problems of bum rehabilitation. This study was done to verify the effects of skin rehabilitation massage therapy (SRMT) on pruritus, skin status, and depression for Korean bum survivors. Methods. A pretest - posttest design using a nonequivalent control group was applied to examine the effects of SRMT for 3 months in a group of 18 bum survivors. The major dependent variables - including pruritus, objective and subjective scar status, and depression - were measured at the beginning and at the end of the therapy to examine the effects of SRMT. Results. Bum survivors receiving SRMT showed reduced pruritus, improved skin status, and depression. The remaining scar also showed improvement in skin pigmentation, pliability, vascularity, and height (compared to the surrounding skin) as measured on the Vancouver Scar Scale (VSS). Conclusions. The findings demonstrate that SRMT for bum survivors may improve their scars both objectively and subjectively, and also reduce pruritus and depression.

ASPS against TGF-${\beta}$ is developing as scar formation inhibitor. The scar was caused by undesired collagen deposition due to overexpression of TGF-${\beta}$ in wounded tissue. The in vitro percutaneous absorption of ASPS(25mer)was investigated by using Furanz Diffusion Cell. The flux of ASPS cannot be found through normal skin due to high molecular weight (MW 10,000) and polyanionic charge. However, the skin permeation of ASPS through tape-stripped damaged skin was markedly increased. The skin fluxs of ASPS were decreased in the following order; hairless mouse> rat >human cadaver skin.

Nuclear steam generator tubes have experienced wear degradation at tube support structure. Morphology of wear scar was analyzed by using eddy current signal. A burst test facility for steam generator tubes was established and tubes with 3 types of defects were tested. The burst test results show that the depth of wear scar is the main factor influencing the burst pressure of tubes, meanwhile, both the longitudinal length and the angle also have effect on the burst pressure. Based on test results, the burst pressure equation for wear degradation was proposed.

On this study, realtime GPS technique and combination of GPS/GLONASS technique are used to extracting coastline. Th￡ object of coastline is Gwanganri beach located in Busan. The coastline is observed along the traces of coastline when high wave of scar by using digital map of 1:1,000 and at random time zone, coastline is surveyed along the boundary line that is contacting with sea water level. When the coastline of random time zone is converted by height of tide table, the coastline when high wave of scar and converted coastline are shown as coincident approximately.

Chronic burn scars often cause various skin malignancies at rates of up to 2%. These lesions are usually squamous cell carcinomas, but rarely, malignant melanoma is reported. We report a 67-year-old male with a malignant melanoma on a burn scar with regional metastasis. This patient presented an ulcerative lesion only in 2 weeks. After histopathological diagnosis, we performed only palliative surgery on patient's demand, and followed up the subsequent deterioration course. Our case reemphasizes the need for rapid diagnosis and treatment when suspect lesions are present on chronic burn scar. Also, physician should be in mind and inform the patient about malignant melanoma and its aggressive course.

Transsexual individuals with gender dysphoria or gender identity disorder are rare, with a prevalence reported to range from 0.002% to 0.014%. Studies have shown that mastectomy yields significant improvements in body image and self-esteem in female-to-male transsexual patients. In patients with grade III breast ptosis, mastectomy with a nipple-areolar complex (NAC) graft is the most commonly used technique, although it has several disadvantages. In the case described herein, a bilateral mastectomy preserving the NAC in an inferior pedicle was performed. Additionally, a thin superior thoracic dermal-fat flap was preserved and eventually sutured at the previous inframammary fold, preventing an inverted T scar. This case shows the advantage of this technique for preserving the blood supply and innervation of the NAC, with a low hypopigmentation risk. Furthermore, in this technique, the patch effect does not impair the results of the NAC graft, and there is no need to use an inverted T scar that may result in thoracic feminization.

The picosecond laser has been widely used to remove tattoos, and improve wrinkles, acne scarring, and pigmented scars. This study was performed to investigate the efficacy and safety of a 1,064-nm fractional picosecond laser treatment for depressed traumatic scars. A total of twenty Korean patients with depressed scars were treated with a 1,064-nm fractional picosecond laser at a two-week interval with a spot size of 3 mm, fluence of 3.5 to 5.5 J/cm², and frequency of 2 Hz with a combination of microlens arrays. At 4 weeks after the final treatment, there was a statistically significant improvement in the modified Vancouver Scar Scale (mVSS) and the patient satisfaction score without any significant complication. A 1,064-nm fractional picosecond laser treatment is a safe and effective method to improve traumatic wound scars with depression.

There is growing interest in minimizing postoperative scarring after a thyroidectomy. Among the many treatment types, laser therapy, especially picosecond-domain laser therapy, is accepted as a standard method. In the present case, a patient with a pigmented, contracted scar was treated using the combination of a picosecond laser and ablative fractional (AF) CO₂ laser. After 15 sessions of 1,064-nm picosecond with micro lens array (MLA) and AF CO₂ laser application, the patient showed significant improvement in their pigmented lesions and scar contracture with no noticeable side effects for 16 months. These results suggest that a combination of picosecond laser with MLA and AF CO₂ laser can treat pigmented, contracted scars safely and effectively.
