현재 시중에는 여러 가지 멀티미디어 단말기를 이용한 다양한 시스템들이 많이 활성화 되어있다. 백화점, 지하철 심지어는 엘리베이터 안에서도 볼 수 있는 멀티미디어 단말기를 이용한 광고 시스템은 정보제공뿐만이 아니라 물품들을 광고하는등 많은 역할을 하고 있다. 하지만 시중에 나와있는 몇몇 시스템들은 많은 단말기들이 넓은 장소에 설치되어있기 때문에 관리자가 어떤 단말기가 고장이 나거나 영상재생을 멈추어도 쉽게 확인할 수 있는 방법이 없다는 단점이 있고, 광고주는 그들의 광고가 얼마나 많이 재생되었는지 그리고 얼마나 많은 사람들이 영상을 봤는지 알 수 있는 방법이 없다. 그래서 이 논문에서는 서버 - 클라이언트 네트워크시스템으로 이루어져 위 요약에서 언급한 문제점을 해결하는 시스템을 논하고자 한다.

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.

The objective of this study was to clarify the reasons of low quality of malting barley at early germination stage caused by rainfall at harvest time. The rainfall undamaged seeds showed higher acid phospatase acivity during water imbibition than did the damaged seeds. The differences in the enzyme activity between the damaged and undamaged seeds became greater by 36 hour imbibition. When GA³was absent in the incubation medium the amount of acid phosphatase within the aleurone cells was higher than that released from the aleurone cells. However, with GA₃ the acid phosphatase released from the aleurone cell walls greatly increased after 36 hour incubation. The undamaged seeds released acid phosphatase more than the damaged seeds, and the difference was greater after 36 hour incubation. The seeds with embryos had higher α-amylase activity than did the seeds without embryos. The α-amylase activity of the undamaged seeds was gradually increased as the imbibition time progressed, but the damaged seeds did not show this tendency. The decrease in the α-amylase activity was directly proportional to the degree of rainfall damage at both incubation treatments with and without GA₃. The α-amylase released from the aleurone cell walls was greatly increased when GA₃ was present in the incubation medium, and the GA₃ effect was higher in the undamaged seed than the damaged seeds. The higher hydrolase activity was observed in the aleurone cell walls of the undamaged seeds. With longer imbibition time, the enzymes released from in the cell walls were detected in the starch granules of endosperm. The severe hydration of starch granules in endosperms of the damaged seeds was observed by scanning electron micrographs.

Marjolin`s ulcer is a rare and often-aggressive cutaneous malignancy that arises in previously traumatized or chronically inflamed skin, particularly after burns. We experienced two cases after burns. Case I involved a forty eight year-old man who had suffered from a flame burn at the parietal scalp area, where had been initially described three years earlier as a full-thickness wound including the pericranium. The man consulted us for a persistent ulcerative and infected wound on the burned lesion during the last 24 months, which turned out on the contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) to be the squamous cell carcinoma with involving the skull and the dura mater. Although the posterior auricular lymph node was enlarged on the ipsilateral side, recent positron emission tomography (PET) CT did not show any metastatic lesion. It was impossible for us to resect the intracranial involvement of the tumor radically, and the postoperative PET CT still showed a focal fluorodeoxyglucose (FDG) uptake around the wall of the superior sagittal sinus. We think that an aggressive combined approach is essential for treatment in early stages for a high success rate, before the intracranial structures are involved because there is no consensus on the treatment for advanced disease, and the results are generally poor. Case 1 also did not involve a radical resection because of the intracranial invasion to the wall of superior sagittal sinus and the possibility of damage to the major cortical veins. He received adjuvant radiotherapy and must be followed periodically. Case 2 involved an eighty six year-old women who suffered from a painful scalp ulcer lesion after flame burns three years earlier. Unlike case 1, neither tumor infiltration into the dura nor lymph node enlargement was observed on the contrast-enhanced computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET) CT. We did a radical resection of the tumor, including the involved bone, and a cranioplasty with bone cement. (J Korean Soc Traumatol 2007;20:52-56)

Glomus tumor is rare benign tumor of the normal glomus, which is a neuroarterial canalsystem called the Sucquet-Hoyer canal. The function of the glomus appears to be to regulate local blood pressure and local heat by blood flow. The etiology of its development is unknown, but some patients have history of trauma. Glomus tumor has been described in the trunk as well as in upper and lower extremits hand (the most common location). The triad of pain, tenderness and sensitivity to cold is characteristics of glomus tumor of the hand. Treatment consists of surgical excision of the lesion under the tourniquet control and magnification for complete removal of the lesion. Glomangiosarcoma or malignant form of glomus tumor is exceptionally rare. Only a few cases have been reported. We experienced five cases of glomus tumor and a cases of glomangiosarcoma treated by complete removal of tumors through partial elevatioin of nail. Typical pain of the lesion was disappeared after operation, also nail deformity did not occurred.
