The study area in the East Sea is located on the northeastern margins of the Ulleung Basin near the Kita-Yamato Bank. The research area provides the important clue to the development of Miocene basins which are characterized by the normal faults and volcanic activities related to rifting in the continental crust. Kita-Yamato Bank is a small sediment-filled graben which was formed by failed rifting in the Early Miocene. The basins rapidly vary the bathymetry, depth of acoustic basement and thickness of sedimentary layer. The tension in the study area caused the extensional lithospheric deformation before/during the Early Miocene. In consequence, tectonic forces resulted in the depression or subsidence of basement from continental rifting in the Kita-Yamato Bank followed by the opening of the Ulleung Basin, and caused the onset of graben or half-graben structure bounded by large blocked syn-rift faults. Afterward no significant tectonic deformation exists, with the consequence that post-rift normal faults with small heave were formed and reactivated by the resultant forces such as tectonic subsidence, sediment loading and volcanic activity. The Cenozoic sediment layer has a maximum thickness of 1.0 s along the center of the graben or half-graben, which overlies the consolidated acoustic basement. Seismic units V and IV supposed to be syn-rift sedimentary rocks are deformed by both the volcanic activities and numerous basement-involved normal faults induced from extension. In the uppermost layer, slump scars resulted from the slope failure are recognized.
Purpose: Anatomically, the foot is provided with insufficient blood supply and is relatively vulnerable to venous congestion compared to other parts of the body. Soft tissue defects are more difficult to manage and palliative treatments can cause hyperkeratosis or ulcer formation, which subsequently requires repeated surgeries. For weight bearing area such as the heel, not only is it important to provide wound coverage but also to restore the protective senses. In these cases, application of flaps for hind foot reconstruction is widely recognized as an effective treatment. In this study, we report the cases of soft tissue reconstruction for which various types of flaps were used to produce good results in both functional and cosmetic aspects. Methods: Data from 37 cases of hind foot operation utilizing flaps performed between from June 2000 to June 2008 were analyzed. Results: Burn related factors were the most common cause of defects, accounting for 19 cases. In addition, chronic ulceration was responsible for 8 cases and so forth. Types of flaps used for the operations, listed in descending order are radial forearm free flap (18), medial plantar island flap (6), rotation flap (5), sural island flap (3), anterolateral thigh free flap (2), lattisimus dorsi muscular flap (2), and contra lateral medial plantar free flap (1). 37 cases were successful, but 8 cases required skin graft due to partial necrosis in small areas. Conclusion : Hind foot reconstruction surgeries that utilize flaps are advantageous in protecting the internal structure, restoring functions, and achieving proper contour aesthetically. Generally, medial plantar skin is preferred because of the anatomical characteristics of the foot (e.g. fibrous septa, soft tissue for cushion). However alternative methods must be applied for defects larger than medial plantar skin and cases in which injuries exist in the flap donor / recipient site (scars in the vicinity of the wound, combined vascular injury). We used various types of flaps including radial forearm neurosensory free flap in order to reconstruct hind foot defects, and report good results in both functional and cosmetic aspects.
Purpose : To evaluate the types of the fibrous scar formation around graft after ACL reconstruction. Materials and Methods : Between Nov 1997 and Jun. 1999, the second look arthroscopy was performed on 15 knees of 14 patients. We evaluated the changes around graft and measured the tunnel position that the tibial tunnel position as a percentage along the length of the tibial plateau from the anterior-to-posterior as seen on a lateral radiograph and the femoral tunnel position as a percentage along Blumensaat's line from anterior-to-posterior as seen on a lateral radiograph. Results : The tibial tunnel position was from $27\%\;to\;58\%(mean\;41\%)$ and the femoral tunnel position was from $58\%\;to\;83\%(mean\;76\%)$, so the tunnel position was ideal in almost cases. By arthroscopic findings, the grafts were not impinged in all cases and tile fibrous scar was formed between intercondylar notch and graft in almost cases except 3 cases. The types of fibrous scar formation were 6 cases of fibrillated fiber and 5 cases of fibrous nodule and 1 case of fibrous band. Conclusion : There was no impingement on graft in all cases and various types of fibrous scars were formed around grafts.
Objective : $^{99m}Tc$-dimercaptosuccinic acid(DMSA) scan is considered to be the most sensitive examination for detection of renal scars. However, because of its high radiation exposure to the kidney and its limited usefulness for patients with low grade vesicoureteral reflux(VUR), some authors have suggested that DMSA scans should be reserved primarily for children with VUR grade 3 and above. The aim of this study was to reevaluate the necessity of DMSA scans as a screening test in infants without reflux or with low grade reflux. Methods : In this retrospective study, 189 infants(mean age : 6.2 months) diagnosed as UTI were enrolled. Voiding cystourethrogram(VCUG), DMSA scan and renal ultrasonography were performed within 1 month of UTI. VUR grade was classified into three subgroups; low grade(grade 1-2), moderate grade(grade 3), and high grade(grade 4-5), respectively. Results : Renal defects were present in 67 of 189 infants, and 82 of the 378 renal units. The incidence of renal defects was significantly correlated with VUR grade(P<0.01); 28 percent without reflux, 38 percent with low grade, 53 percent with moderate grade, 100 percent with high grade, respectively. However, there was no significant differences in incidence of renal defects between the low grade and moderate grade group. Conclusion : In this study, renal defects were found in quite high percentages; 28 percent patients without reflux and 38 percent patients with low grade VUR, respectively. Moreover, there was no significant difference in the incidence of renal defects between the low grade and moderate grade groups. Therefore, DMSA scan should be performed for infants with UTI as a screening test regardless of the presence of VUR.
Purpose: The Abbe flap procedure has been used to correct disharmony of the upper and lower lips as well as for making a philtrum for patients with secondary cleft lip deformities. But the Abbe flap procedure adds two scars in addition to the prior operative scar on the upper lip. This study was conducted to determine the treatment outcomes of esthetic subunit excision of the scar on the philtrum and Abbe flap coverage for correction of cleft lip deformities with photogrammetric analysis. Methods: This study investigated a total of 11 patients with cleft lip deformities who underwent scar excision with Abbe flap coverage, and the patients were followed up for at least 6 months. Under general anesthesia, a mushroom-shaped Abbe flap was drawn on the lower lip with a width of 8 mm and a height 1~2 mm longer than that of the philtral midline. The epidermis and dermis of the scar on the upper lip were excised. In the cases with alar base depression, the orbicularis oris muscle was split vertically and transposed to the alar base. The Abbe flap was harvested as a pedicled flap containing a small amount of muscle and this was rotated 180-degree to be inserted into the upper lip. Mucosa, muscle, subcutaneous tissue and skin were closed in layers. The flap was divided at the 7~14 postoperative day. The postoperative outcomes were evaluated by using photogrammetric analysis. Three indices were measured from the standard clinical photographs taken before and after the surgery. For anthroposcopic assessment, observers described the postoperative outcomes using an ordinary scale method. Results: The postoperative values obtained in the photogrammetric analysis showed improvement as compared with the preoperative ones. Improved anthroposcopic outcomes were also noted. Conclusion: Scar excision and Abbe flap coverage were proven to be effective in improving protrusion and the height of the upper lip, the scar of the upper lip and the symmetry of Cupid's bow and the philtral column, as well as formation of the philtral dimple.

In July 2011, hundreds of garden cosmos (Cosmos bipinnatus) were found to be infected with a white smut in Namyangju. Further surveys in central Korea showed that the disease occurred in all the nine localities visited, with disease incidence rate of >50%. Symptoms manifested as pale-green to chlorotic areas on the leaves, followed by white mildew development on lesions. The lesions usually coalesced and became necrotic, considerably reducing the aesthetic value. Caespituli were initially hypophyllous but later epiphyllous as well. Conidiophores were 10-40 in moderately dense fascicles, hyaline throughout, mostly guttulate, $20-45{\times}2-4{\mu}m$, obtuse at the apex, and had inconspicuous conidial scars. Conidia were solitary, botuliform, hyaline, aseptate, mostly guttulate, apex rounded, base rounded to truncate, $17-24{\times}3.5-5{\mu}m$, hilum inconspicuous, unthickened, and not darkened. Sori were rounded to elongated, resulting in first white and later brown leaf spots. Teliospores embedded in the leaf tissue were subglobose to ellipsoidal, subhyaline to pale yellowish-brown, $12.5-20{\times}10-15{\mu}m$. These morphological characteristics corresponded with those of Entyloma cosmi V$\acute{a}$nky, Horita & Jage. This is the first report of white smut disease of garden cosmos due to infection of E. cosmi in Korea.

Background: The cheek rotation flap has sufficient blood flow and large flap size and it is also flexible and easy to manipulate. It has been used for reconstruction of defects on cheek, lower eyelid, or medial and lateral canthus. For the large defects on central nose, paramedian forehead flap has been used, but patients were reluctant despite the remaining same skin tone on damaged area because of remaining scars on forehead. However, the cheek flap is cosmetically superior as it uses the adjacent large flap. Thus, the study aims to demonstrate its versatility with clinical practices. Methods: This is retrospective case study on 38 patients who removed facial masses and reconstructed by the cheek rotation flap from 2008 to 2015. It consists of defects on cheek (16), lower eyelid (12), nose (3), medial canthus (3), lateral canthus (2), and preauricle (2). Buccal mucosa was used for the reconstruction of eyelid conjunctiva, and skin graft was processed for nasal mucosa reconstruction. Results: The average defect size was $6.4cm^2$, and the average flap size was $47.3cm^2$. Every flap recovered without complications such as abnormal slant, entropion or ectropion in lower eyelid, but revision surgery required in three cases of nasal side wall reconstruction due to the occurrence of dog ear on nasolabial sulcus. Conclusion: The cheek rotation flap can be applicable instead of paramedian forehead flap for the large nasal sidewall defect reconstruction as well as former medial and lateral canthal defect reconstruction.
This morphological study was carried out to investigate the healing effect of open and occlusive dressing on rabbit skin wounds. The male white rabbits were given incision wound measuring 1.0cm in length and excision wound measuring $1.0{\times}0.2cm$ respectively on backs. Five rabbits among their received sterilization with beta dine twice a day and kept wound open. Another group of rabbits received sterilization and occlusive dressing with application of 1% sulfadiazine ointment and covering of gauze. The rabbits were observed at 5, 10, and 15 days after dressing with light microscope. The results were as follows. Both incision and excision wounds received open and occlusive dressing respectively revealed formation of scab and regeneration of epidermal epithelial cells at wound margin. The superficial dermis showed infiltration of neutrophils, monocytes, and lymphocytes, fibroblastic proliferation, and edema. On 10 days after opera and occlusive dressing the scab had disappeared and regeneration of epidermal epithelium was completed. The capillaries and inflammatory cells were decreased in number. However, edema and fibroblastic proliferation were more pronounced. On 15 days after opera and occlusive dressing, there were keratinization of regenerated epidermal epithelium, loss of inflammatory infiltration, edema, and capillary proliferation, and increase of fibroblastic proliferation and collagen fibers. The amounts of scars were less in incision wound than of excision one. There were no differences in healing processes between both dressing methods. According to the above results, it was conceived that sterilization of wound is more important in wound healing than dressing method in trivial wounds.

Objectives The purpose of this study is to understand what caregivers think advantageous and disadvantageous regarding Acupoint sticking Dog-days. Also, to know whether Acupoint sticking in Dog-days affect vital signs, and to investigate if occurrence of side effects are related to application duration, sweat, or compliance to precautionary measures. Methods Survey has been handed out to parents of the children who took Acupoint sticking in Dog-days. 10 days after the first dose was administered, survey was performed to examine any side effect occurrences, characteristics of sweat, duration of application, parents' thought about this therapy. Also, vital signs were checked before the first dose, and 10 days after to see any differences in vital signs in regards to this therapy. Results Preferable opinions about Acupoint sticking in Dog-days are 'convenient than herbal medications' (76.5%), 'less reluctance of child' (47.1%), 'reasonable price' (20.6%), 'good effectiveness' (17.6%), 'less side effect' (14.7%), 'no worry about agrochemicals or heavy metals uptake' (11.8%). Downsides were 'difficult to admit to hospital right on the Dog-days' (73.5%), 'no conspicuous effectiveness' (11.8%), 'expensive' (5.9%), 'reluctance of child' (2.9%). Vital sign differences were minimal when examined before and after Acupoint sticking in Dog-days. Side effects occurred 5 times in 34 cases, and they were erythema, itchiness, and hot sensation. There were no scars or blisters reported. All 5 cases were resolved without any interventions within 3 days. Conclusions Acupoint sticking in Dog-days doesn't affect vital signs. Severe side effect is rare, reported side effects were relatively mild, suggesting that it may be safe and well-tolerated. 'Convenience' (76.5%) is biggest advantage of Acupoint sticking in Dog-days and 'less reluctance of child' is also big advantage of Acupoint sticking in Dog-days. 'Difficulty to admit to hospital right on the Dog-days' (73.5%) is biggest disadvantage of Acupoint sticking in Dog-days.
This study was to examine how Art Therapy affected improving Self-Esteem and Ego-Resiliency, Emotional Stability of Sexual Victimized Adolescent. The subject was the middle school student girl, 3th grades(15year old). She was suffered from sexual assault she was lack of self-confidence and suffered difficulty in daily life. Individual Art Therapy was performed once a week for 60 minutes and for 20 periods. Emotional Stability, Self-Resilience, Self-Esteem were performed pre-post test to verify the effectiveness of the program. The results obtained after Art Therapy were as follows. Firstly, The Self-Esteem score improved to post- 35 points from pre-16points. The Ego-Resiliency score improved to post-133points from pre- 63 points. The Emotional Stability score changed to a post-ex-post 96 score with a score of 110 as a positive effect. Secondly, the subject in the whole process of Art Therapy were formed intimacy with the researchers, able to heal painful scars while expressing inner feelings in a stable psychological state. Through the creative activities, she became confident and had positive thoughts about his future. Even though, this program focused to prevent PTSD.
