  • Natural Killer/T-cell(NK/TC) lymphoma is a rare disease of oral and maxillofacial region with an aggressive clinical course, showed unusual clinical manifestations. Prognosis is generally poor and the disease is invariably fatal after systemic dissemination. A case of nasal NK/TC non-Hodgkin's lymphoma in the left maxilla that showed unusual clinical manifestations and a fulminant course of disease, are described with literature reviews. A 81-year-old female patient presented with rapidly growing ulceration and general malaise after extraction of right upper second premolar NK/TC lymphoma was subsequently detected by biopsy. rapid and wide invasion from maxilla to mandible developed within 10 days and multiple metastasis to whole body was after a few weeks. Although the time relationship is not clear, local invasion and multiple metastasis could be dissemination from localized disease of NK/TC. As seen in my case, the course can be excessively aggressive and fulminant even though it first appeared as a localized ulceractive lesion. She is expired 2 months after biopsy. Positivity of immunohistochemical stain (CD56, LCA, UCHL-1, CD3), which is a specific characteristic of NK/TC, may serve as a factor showing a poor prognosis of a malignant lymphoma

  • Objective: This experiment was conducted to investigate the effects of fungal treated oil palm fronds (FTOPF) on performance, carcass traits, meat quality, and muscle chemical composition. Methods: Eighteen growing crossbred male goats (Thai Native${\times}$Anglo Nubian) with $18.7{\pm}2.0kg$ of initial body weight (BW) were stratified and blocked by BW in a randomized complete block design. Three diets containing 30% of oil palm fronds (OPF) either untreated (UOPF) or treated with Lentinussajor-caju (FTOPF) with or without urea (FTOPFU) were used as roughage sources in total mixed rations (TMRs). The diets were offered ad libitum and weight gain was determined. At the end of the experimental period, the harvest data and carcass characteristics of the goats were recorded, and muscular longissimus dorsi composition was determined. Results: No significant effect of fungal treated (FT) inclusion was observed in any of the feed intake, growth performance, and carcass characteristics. Likewise, no apparent effects on carcass composition and muscle chemical composition were detected in this study, except for hind leg and chump were affected (p<0.05) by FT inclusion. Conclusion: In conclusion, feeding of fungal (Lentinussajor-caju) treated oil palm frond in TMR diet did not affect performance and carcass characteristics in finishing goats.

  • A new type of macrolides, lincosamides and streptogramin B antibiotics (MLS) resistance, showing the characteristic phenotype growing within the inhibition zone area around the clindamycin disk, was identified among clinically isolated Staphylococcus aureus. We named the phenotype as MLS resistance with foggy-D shape (fMLS). The average frequency of MLS isolates was 9%. All of fMLS isolates have only erm(A) for the resistance determinant. The growth pattern of the challenged MLS isolate looks intermediate phase between the patterns of inducible MLS resistance and constitutive MLS resistance.

  • Most of battery industries are growing explosively as a core strategy industry for the development of the semi-conductor, the LCD, and the mobile communication device. In this thesis, dynamic characteristics of the steel can labeling machine on the automatic cell assembly line are studied. Dynamic characteristic analysis consists of dynamic behavior analysis and finite element analysis and is necessary for effective design of machines. In the dynamic behavior analysis, the displacement, velocity, applied force and angular velocity of each components are simulated according to each part. In the FEA, stress analysis, mode analysis, and frequency analysis are performed for each part. The results of these simulations are used for the design specification investigation and compensation for optimal design of cell manufacturing line. Therefore, Virtual Engineering of the steel can labeling machine on the automatic cell assembly line systems are modeled and simulated. 3D motion behavior is visualized under real-operating condition on the computer window. Virtual Prototype make it possible to save time by identifying design problems early in development, cut cost by reducing making hardware prototype, and improve quality by quickly optimizing full-system performance. As the first step of CAE which integrates design, dynamic modeling using ADAMS and FEM analysis using NASTRAN are developed.

  • Genus Alnus are deciduous board-leaved trees or shrubs found in the damp place and mountain and more than 17 species are growing in Korea. The bark of Alnus japonica has been used for the treatment of fever, hemorrhage and diarrehea in oriental traditional medicine. Quantitative analysis of diarylheptanoids which were characteristic components of Alnus species (A. japonica, A. hirsuta, and A. hirsuta var. sibirica), has been conducted by HPLC. The results showed that these plants were rich source of diarylheptanoids and the amount of oregonin and hirsutanonol which were major diarylheptanoids showed seasonal variation.

  • Neurofibromatosis is very rare syndrome characterized by abnormal cutaneous pigmentation and numerous skin tumors was described by Smith in 1849, which is inherited as an autosomal dominant trait. Von Recklinghausen reported 2 cases of multiple skin and subcutaneous tumors in 1982. Malignant peripheral nerve tumors, although generally rare, are one of the most characteristic malignant tumors associated with Neurofibromatosis. We have experienced 3 cases of malignant Schwannoma in neurofibroma patients from 1982 to 1988 for 6 years at Thoracic and Cardiovascular surgery department, College of Medicine, Yonsei University, Seoul, Korea. l. One is 62 years old female who was taken total hysterectomy followed by irradiation treatment due to Uterine Carcinoma 21 years ago. She had a large bulging mass on left anterior chest wall and was taken enbloc resection of tumor including rib confirmed malignant Schwannoma. 2. Another is 18 years old female who had large bulging mass on right chest wall and pleural effusion in right thoracic cavity. Thoracentesis revealed a large amount of lymphocytes misdiagnosed of Tbc, pleurisy with Neurofibromatosis. We performed tissue biopsy on bulging mass and the specimen was confirmed malignant Schwannoma 2 months after first diagnosis of Tbc. pleurisy. She was not accessible to radical resection because of far advanced malignant Schwannoma at that time. 3. Third case is 28 years old male who was taken enbloc resection of tumor including rib due to Neurofibroma with Neurofibromatosis at M. hospital 6 months ago. But he had rapid growing mass at operation site again and taken tissue biopsy confirmed of malignant Schwannoma. He was not accessible to enbloc resection due to malignant Schwannoma extending to mediastinal structures.

  • The growth of GaN on Si is of great interest due to the several advantages : low cost, large size and high-quality wafer availability as well as its matured technology. The crystal quality of GaN is known to be much influenced by the surface pretreatment of Si substrate[1]. In this work, the properties of GaN overlayer grown on ion beam modified Si(111) have been investigated. Si(111) surface was treated RIB with 1KeV-N$_2$$\^$+/(at 1.9 ${\times}$ 10$\^$-5/) to dose ranging from 5${\times}$10$\^$15/ to 1${\times}$10$\^$17/ prior to film growth. GaN epilayers were grown at 1100$^{\circ}C$ for 1 hour after growing AlN buffer layers for 5∼30 minutes at 1100$^{\circ}C$ in Metal Organic Chemical Vapor Deposition (MOCVD). The properties of GaN epilayers were evaluated by X-Ray Diffraction(XRD), Raman spectroscopy, Photoluminescence(PL) and Hall measurement. The results showed that the ion modified treatment markedly affected to the structural, optical and electrical characteristic of GaN layers.

  • From 1995 to 2005 the information related to clothing and textiles publicized by 6 journals regarding Elder Women's body type was collected and analyzed. The results are as follows. 1. It has been investigated into the elder woman's body type since 1995, and this subject needs a detailed study. in audition, investigation into woman's body type has been studied parts of the body for clothing construction. 2. Analysis result for measure area preponderance(Seoul area and local metropolitan city) of area, measure subject number mainly to large scale group more than 300 people that measure is consisting most know can. 3. Where the way of measurement is concerned, there are direct measurements more than indirect measurements. In case of using just direct measurement, the study often mentions necessity of indirect measurements. Therefore it is thought simultaneous measurement is the most desirable. 4. A Body type characteristic of elder woman shows a size of every part diminishes as growing older. Owing mainly to obesity of waist and abdomen, they have a changed body a measure of around the abdomen is bigger than around the hips. hips drop and the upper half of the body down, and besides, feet are changed into the flat.
