Amyotrophic Lateral Sclerosis(ALS) is a fatal neuromuscular disease characterized by progressive muscle weakness resulting in paralysis. ALS is characterized by both upper and lower motor neuron damage. Diagnostic tests include magnetic resonance imaging(MRI) electromyogram(EMG), muscle biopsy, and blood tests. In order for a definitive diagnosis of ALS to be made, damage must be evident in both upper and lower motor neurons. When three limbs are sufficiently affected, the diagnosis is ALS. There is no cure for ALS. We recently experienced one case of ALS, The patients was diagnosed as ALS by EMG and Symptoms. We diagnosed her as Wea jeung and treated by Herbal-medication based on the differentiation of symtoms. we report change of his symptoms through both western medical treatment and oriental medical treatment.

Performance of a video browser greatly depends on the performance of scene change detection for the efficient retrieval and storage of the video contents which are major data in a current contents management system. In this paper we propose a new scene change detection method using Mean Difference Histogram of each frame section which improves accuracy of scene change detection as well as reduces the frequency of miss detection and fault detection of gradual scene change which is one of critical problem of the conventional histogram-based techniques.

With an aim to disclose causal factors scably grains intoxications, the screening of toxic Fusaria and the detection of toxic priniciples were performed in respect of cultured cells bioassay with HeLa cells, skin-necrotizing effect, histopathological investigation and also chromatographic analysis sith following results ; 1. Among the fungi, Fusarium sp. F-27, F-63 and F-61 were highly toxic to mice, causing liver injury characterized necrosis and inflammation. 2. HeLa cell culture bioassay demonstrated that the cell of the isolated strains of Fusaria were suspected to produce toxic material (Fusarenon-X). 3. The culture filtrates of Fusarium nivale Fn-2B, F-27, and F-63, were injected subcutaneously, and caused inflammation followed by crust on the skin ICR-mice. 4. The observation method of skin-necrotizing effect to the mice can be used to the screening to the toxin-producing fungi isolated from many fusarial contaminations.

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a benign mesenchymal lesion with incidental histologic findings. Surgical excision is recommended as the treatment of choice for PASH, although the recurrence rates after excision range from 15% to 22%. A 46-year-old-female presented with a six-month history of bilateral breast enlargement and painful sensation mimicking inflammatory carcinoma. Imaging studies demonstrated innumerable enhancing nodules in both breasts. Due to the growth of the lesions and progressive clinical symptoms, bilateral subcutaneous mastectomy was performed. Grossly, the specimens were round and well-circumscribed, and the histologic examination revealed PASH. After mastectomy, we created a pocket with the pectoralis major muscle and a lower skin flap, which was deepithelized. Anatomical mammary implants were inserted, and the nipple areolar complex was transferred to a new position as a free graft. The aesthetic result was satisfactory after twelve months of follow-up.

This study aims to identify the special features of high-concept funology observed in fashion products and expressional media by exploring funology in an era of high-concept, the emotional paradigm of the 21st century. High-concept funology in today's fashion can be explained as follows: First, 'virtual reality', which is often seen in fashion shows and fashion commercials, enhances consumer participation and involvement with blurred boundaries between the real world and the virtual world. With the expansion of various forms of real-time communication with consumers, positive images of the brand are being projected to the consumers. Second, 'form transformability', which is often found in fashion products, promotes customers' purchase desire as they are able to present themselves in a more versatile way in the fashion product that is changeable in various designs. Third, 'integration of different fields', which is easily found in various fashion goods, engages consumers in a mutual interaction under an entertaining setting with the product that is made to satisfy their needs attuned to their digital lifestyle. Fourth, 'interactive responsiveness', which is mainly recognized in fashion stores and commercials, is characterized by its interactive playfulness that encourages consumer participation through entertainment contents and promotes brand intimacy, eventually adding more value to its name.

In many cases of complete ear amputation, microvascular surgery is required for tissue perfusion and organ survival. However, microvascular reconstruction is not always feasible in the absence of suitable vessels. Here, we present the case of a 76-year-old man who underwent complete amputation of the left ear after a collapse at home because of cardiogenic syncope. He was treated with primary replantation and underwent a postoperative salvage course including continuous local hyperbaric oxygen therapy (HBOT), platelet-rich plasma (PRP) injections, and polydeoxyribonucleotide (PDRN) injections. The ear was almost completely salvaged, with a tiny eschar at the mid-scapha on both the anterior and posterior aspects. This case demonstrates the efficacy of local HBOT with PRP and PDRN injections.

Red ginseng is a medicinal herb widely used in East-Asia for a long time. Recently there have been a lot of studies about the effect of red ginseng on the immune responses. We investigated the differences between Korean red ginseng and Chinese red ginseng in the lymphocyte proliferation and cytokine production. The rats were divided into 3 groups, KRG(Korean Red Ginseng) group, CRG(Chinese Red Ginseng) group, and the Control group. Experimental groups were administered with Korean and Chinese red ginsengs for three months respectively. Then we obtained the lymphatic cells from spleen and compared the ability of KRG on the lymphocyte proliferation and the cytokine production after mitogen-stimulated culture to CRG. The proliferation of lymphocyte and level of $IL-1{\alpha}$ were significantly increased only in KRG group. There were significant increases in the level of $INF-{\gamma}$ in both KRG and CRG groups. There were no significant differences in the level of IL-2 and $TNF-{\alpha}$. These results indicate that KRG can induce infection-relevant immune responses much faster and higher than CRG. Furthermore, functional activation of CD8+ T-cell may be activated by red ginsengs.

The viscosities of benzene have been determined at several temperatures and pressures to investigate the effect of temperature and pressure on the viscosity of benzene in liquid phase. When a falling ball viscometer with a constant volume contained a given amount of liquid benzene at desired temperatures and pressures, the viscosities of benzene in the viscometer could be evaluated from the measurements of the falling time of a skinker. The variations of the specific volume and the free volume of liquid benzene with temperature and pressure were, from the results, searched out. Finally, the effects of temperature and pressure on the viscosity of benzene were discussed by means of the variations of free volume with temperature and pressure.

In this study, numerical studies using a Computational Fluid Dynamics(CFD) method were carried out to estimate the green water load acting on the breakwater plate of bow deck of container carrier, KCS. For the green load water load analysis, a full load condition was considered. The relative motions at bow deck were calculated from the seakeepig analysis. Statistical analysis were carried out to estimate the long term response of the relative motions with the North Atlantic wave scatter diagram. The equivalent design wave was determined from the RAO of the relative motions at bow and the long term responses. CFD geometry modeling with three different locations and simulations for the green water loads were carried out in the equivalent design waves. A commercial CFD program, STAR-CCM+ Ver. 8.04, was used and the green water pressures on the breakwater plate were calculated successfully. The CFD analysis for green water loads can be used as a useful design tool for the evaluation of the breakwater plate of the container vessel.

It is essential to find oscillating angles and periods in a seaway when designing and manufacturing stabilizers. It is difficult to find oscillating angles and periods in high speed turning and they vary with ship speed and wave heading angles, therefore, proper algorithm to measure oscillating periods in a seaway. In the present study, three kinds of algorithms are developed to measure oscillating angles periods in a seaway. Dual axis tilt sensor of low price is used to measure oscillating angles, and the effect of lateral accelerations on tilt sensor have been reduced by the fusion algorithm using the gyro sensor signals. Analog and digital filters are applied to minimize the noise of the signals. Three kinds of algorithms, zero crossing, peak to peak and moving zero crossing algorithm, are developed to measure oscillating periods in a seaway. It is found that the moving zero algorithm showed the best results in the sea trials.
