Purpose: The recent development of MR has made to possible radiological diagnosis in various soft tssue tumors. But multifarious components within soft tissue tumors and their periodic change have made to difficult even differentiation of malignant from benign soft tissue tumors solely on the MR. So authors retry to differentiate malignant from benign soft tissue tumors with clinical and MR finding complex. Materials and methods: We were analysed 82 pathologically confirmed soft tissue solid tumors (37 cases as malignancy including intermediate tumors and 45 cases as benign including inflammatory masses) which are correlated with clinical findings such as age, size, and location, MR findings such as tumor border, texture on T2 and contrast-T1 images, and enhancement area retrospectively. Many typical lipoma and cysts including of ganglion and abscess are rejected in the benign soft tissue tumor group because not difficult to diagnose on MR. Results: Malignant soft tissue tumors were more frequent in 21~40 and 61~80 years old of the age, above 3.0 cm of the size, trunk-pelvis-lower extremities of the location, and MR findings with irregular border and above 50% of the enhancement area than those of benign soft tissue tumors. Conclusion: The clinical finding that divided to two locations as trunk-pelvis-lower extremities and upper extremities-shoulder-spine was statistically significant to differentiate malignant from benign soft tissue solid tumors. However, the others would provide some useful informations to differentiate them never specific.

Purpose: Compared to soft tissue sarcoma, the relative risk of extraskeletal osteosarcoma is still not clear. The purpose of this study is to identify the difference in survival and local recurrence rate between two soft tissue sarcomas. Materials and Methods: Twelve patients with pathologically confirmed extraskeletal osteosarcoma were analysed. For retrospective matched case-control study, we selected 72 patients who were confirmed as high grade soft tissue sarcoma and had similar tumor location, tumor size and age to extraskeletal osteosarcoma. Results: Median age was 50 years old. Five cases were located in upper extremity, four in the buttocks, three in the lower extremity. Overall survival rate of extraskeletal osteosarcoma group and high grade soft tissue sarcoma group at 5 years were 52% and 55%. There is no significant difference (p=0.8). Local recurrence rate and metastasis rate were 58%, 67% in extraskeletal osteosarcoma group and 36%, 51% in soft tissue sarcoma group, which were not stastistically significant(p=0.2, p=0.4). Conclusion: Extraskeletal osteosarcoma have similar local recurrence, metastasis and survival rate compare to high grade soft tissue sarcoma. The number of patients of this study were too small to identify outcome of extraskeletal osteosarcoma. Further multi-institutional study should be attempted.

This study was undertaken to investigate the effect of cognitive rehabilitation program (CRP) using virtual content, for recovering patients with cerebrovascular disease (CVD). A total of 34 patients with CVD were divided into a control group and an experimental group, and subsequently subjected to a virtual content based CRP, followed by cognition, ADLs, and upper limbs. The control group completed a universal rehabilitation program (URP), and the experimental group was provided a URP and a virtual content based cognitive rehabilitation program. For both groups, respective programs were conducted twice a day, 5 times a week for 4 weeks. Both groups showed significant improvement in ADLs (p<0.05); but the amount of change in the experimental group 5 point improved significantly (p<0.05). Cognition was significantly different for both groups (p<0.05). However, the experimental group showed a greater change (2 point) than the control group when considering the amount of change (p<0.05). Comparing the amount of change in the upper extremity, the experimental group showed a significant change (0.7 point) than the control group (p<0.05). This study confirms that compared to URP, CRP using virtual content significantly improves ADLs and cognition.

A specimen of Arnoglossus polyspilus (G$\ddot{u}$nther) (229.0 mm standard length) belonging to the family Bothidae, collect from the coastal waters of Jeju Island, represents the first record of the species from Korea. This species is characterized by having caudal fin with two simple rays on both upper and lower margins, several anterior dorsal fin rays somewhat elongated, upper jaw extending to below anterior 1/3 of lower eye, and one gill raker on the upper limb of the first gill arch. We add this species to the Korean fish fauna and propose its new Korean name, "No-rang-ban-jeom-ga-ja-mi".

Objective : This study was designed to investigate the anti-oxidative potentials to wide the usage of Morus alba L. derived from medicinal herbs on cosmoceutical fields. Methods : Anti-oxidative potentials were investigated by using several kinds of assays including electron donating ability, and the total contents of phenolic compounds were also measured. In some cases TLC (Thin Layer Chromatography) method were used to identify the patterns of phenolics in herbal extracts. Results : Aurones which are sub-types of flavonoids were observed in methanol extract of Mori Cortex Radidus, and total phenolic contents in Mori Cortex Radidus were more than in methanol extracts of Mori Folium and Mori Ramulus. Various kinds of phenolic compounds were observed in chloroform fraction of Mori Cortex Radidus. Conclusion : According to these results, the chloroform fraction of Mori Cortex Radidus could be the most possible resource that has potentials on anti-oxidant agents on cosmoceutical fields.

In this study, The purpose is to understand the influence of lovemark on relation continuing intention. As a result of reliability analysis, the Cronbach's α coefficient of all variables such as lovemark, relation continuing intention showed 0.8 or more, thus ensuring reliability. The results of regression analysis between variables for hypothesis testing are as follows. as a result of analysis on the effect of lovemark on the relation continuing intention, it showed that both factors of love and respect dimension had significant influences, and that the relationship intension also increased as the love and respect dimension increased. As a result of this study, In order to increase lovemark and relationship intension, it was also confirmed that efforts should be focused on immersion between airlines and customers. It was confirmed that efforts to increase the airline's lovemark are needed to retain existing customers and attract new customers.

Nodular fasciitis is a benign proliferative lesion of the fibroblasts and/or myofibroblasts, generally detected in the soft tissue of the upper extremities. It has also been reported in the lower extremities, head, and neck, and rarely in the breast. Its rarity and nonspecific clinical and radiological features resemble those of malignant tumors of the breast and make the differential diagnosis and management difficult. Herein, we present a rare case of nodular fasciitis of the breast, which was initially suspected to be a phyllodes tumor.

The maps produced by the NGII(geographical information institute) are composed of 1/1,000, 1/2,500, 1/5,000 large scale maps, 1/25,000, 1/50,000 and smaller scale maps. 1/1,000 digital map, as the most large-scale digital map made by the NGII, has been constructed with the beginning of NGIS(national geographic information System) Project in 1995. However, 1/1000 digital maps have been not produced by the fundamental survey on the basis of systematic planning at the national level, but a lot of parts have been constructed by the public survey for the purpose of the fiscal year of the local governments. Also, these maps have been not regularly updated because of big budget. In this study, we investigated problems related to the construction status, system, and area, and suggested plans that can improve these problems. As the improvement plan, we proposed a nationwide three regionalization for short-term modification and long-term regular update, reset of core downtown boundaries based on topographical features, diversification of budget execution method and an improved execution system.

The aim of this study was to investigate upper and lower limb muscle activity using EMG(electromyogram) sensors while walking and identify normal gait pattern using FSR(force sensing resistor) sensor. Fifteen college students participated in this study and their EMG and FSR signal were measured during stopping and walking trials. EMG signals from upper(pectoralis major and trapezius) and lower limbs(rectus femoris, biceps femoris, vastus medialis, vastus lateralis, semimembranosus, semitendinosus, soleus, peroneus longus, gastrocnemius medialis, and gastrocnemius lateralis) were obtained using the surface electrodes. FSR measured pressures on 8 areas of the sole of the foot during walking. EMG results showed that all muscle activities except for vastus lateralis and semimembranosus during walking had higher amplitudes than stopping. Additionally, muscle activities associated with stance and swing phase during walking were identified. Results on FSR showed that stance and swing phases were detected by FSR signals during a gait cycle. Eight gait phases－initial contact, loading response, mid stance, terminal stance, pre swing, initial swing, mid swing, and terminal swing- were classified.
