Objectives: The aim of this study was to investigate the correlation between fatigue degree and Comprehensive diagnosis of Qui Xui Shui in patients with functional dyspepsia. There again, we investigated an association between scores obtained from Comprehensive diagnosis of Qui Xui Shui and state of skin sympathetic tone or cardiovascular reactivity. Methods: Subjects were 56 patients with Functional dyspepsia and 8 healthy People. Fatigue degree was assessed by questionnaires consisting of subjective complaints of fatigue. Comprehensive diagnoais of Qui Xue Shui was investigated by questionnaire and physical examination, total score and composition score were calculated from the symptom score. Skin sympathetic tone was measured by Ryodoraku Score(RS) and Cardiovascular Reactivity(CV Reactivity) was checked by Pulse diagnostic apparatus. All patients were divided into two groups by RS $40{\mu}A$(below and above) or by CV Reactivity(decreased and increased or not decreased). Results: There was highly significant correlation between Fatigue Degree and total score and each composition score of Comprehensive diagnosis of Qui Xui Shui. And total score of patients was significantly higher than that of health controls : in the patients, females than males. Significance related with the level of RS $40{\mu}Aor$ the state of CV Reactivity were not remarkable in both patients and health control group. Conclusions: Fatigue degree seems to have a special feature reflecting the state of Comprehensive Diagnosis of Qui Xui Shui in patients with functional dyspepsia.

Myxofibrosarcoma represents one of the most common soft tissue sarcomas of the extremities in adult and elderly patients. However, it only rarely occurs in the chest wall. A 58 years old woman presented with a huge painless lump (8 ${\times}$ 6.5 cm) in the right lower parasternal area which recurred a few months following excision from General surgery of our hospital. Histology showed an infiltrative deep seated dermal and subcutaneous tumor. It had a distinctive lobular growth pattern with prominent myxoid change and moderate cellularity. Tumor cells were spindleshaped with varying degrees of pleomorphism and frequent mitotic figures. Numerous blood vessels with curvilinear growth pattern were also seen. Immunostains for S-100, CD68, Mac 387, and FX IIIa were all negative, but positive for Vimentin. The histologic feature was of an intermediate grade myxofibrosarcoma. Wide excision was performed and recovered in good condition without any physical disabilities and was discharged at one month later. Currently she is waiting for the skin graft without chemotherapy and radiotherapy.

In the late 1980s, 5 new towns such as Bundang, Ilsan, Pyeongchon, Sanborn, Jungdong were constructed to solve housing problems and to disperse functions concentrated within Seoul. As the city got matured, it began to appear the initial signs of urban problems such as aging of high rise-density apartment sites, traffic congestion, lack of parking spaces and aging of infrastructure. Therefore, in order to cope with urban problems, it is very important to apprehend the process of urban growth, its change and the feature of physical/human elements. So, the purpose of this thesis is to analyze the changes in housing and population characteristics for past 20 years by use of Census data from 1995 to 2010. First, the new town's goal of population and housing plan at the time of construction was analyzed how it was achieved, and it is close to the performance of the goal. And the trend of changes in the population and household characteristics was analyzed by every five year's data. As the result of analysis, it shows socio-demographic changes such as aged and elderly population growth, rapid increase in one generation's household and single person household, highly educated city, monthly rent household's increase and charter household's reduction. Results of this analysis can be utilized to aforethought management of new towns. But it is required more sustained and systematic urban monitoring and data analysis because the one-off analysis of the city's characteristics alone is difficult enough to grasp them.

Recently demand for the 3D modeling technology to reconstruct real world is getting increasing. However, existing geospatial data are mainly based on the 2D space. In addition, most of the geospatial data provide geometric information only. In consequence, there are limits in various applications to utilize information from those data and to reconstruct the real world in 3D space. Therefore, it is required to develop efficient 3D mapping methodology and data for- mat to establish geospatial database. Especially digital elevation model(DEM) is one of the essential geospatial data, however, DEM provides only spatially distributed 3D coordinates of the natural and artificial surfaces. Moreover, most of DEMs are generated without considering terrain properties such as surface roughness, terrain type, spatial resolution, feature and so on. This paper suggests adaptive and flexible geospatial data format that has possibility to include various information such as terrain characteristics, multiple resolutions, interpolation methods, break line information, model keypoints, and other physical property. The study area was categorized into mountainous area, gently rolling area, and flat area by taking the terrain characteristics into account with respect to terrain roughness. Different resolutions and interpolation methods were applied to each area. Finally, a 3D digital map derived from aerial photographs was integrated with the geospatial data and visualized.

Arranging 63 kinds of separate volumes and papers published on Oriental medicine, I could get the result as follows. 1. The herbs for internal application used commonly in vitiligo are 155 kinds totally. The herbs for external application are 67 kinds. The herbs for external and internal both application examined into 23 sorts. 2. Herbs for weakness syndrome in vitiligo are 49 kinds. Another type, excess syndrome is 105 sorts, the'latter is roughly twice as many as the former. 3. It is as follows that the results of study in relations to kinds, factors, and medical treatments of herbs about vitiligo in and out of the country with the division of former times to 1900, 1901 to 1980, 1981 to 1990, and 1991 to the latest day. In comparative study of inner and outer of thc country about factors and medical treatments of vitiligo in chronicle classification, its factors in the internal documents are classified by outside factors. Although there arc the differences of factors by each epoch, however, the factors of vitiligo according to external documents are blood stasis(血熱), deficiency of um of the liver and kidneys(肝腎陰虛), deficiency of blood(血虛), excess of exhaustion(勞倦過多) etc. Moreover, the medical treatment is more diverse and the differences by each epoch as to the medical treatment is also put down more saliantiy than in internal documents. 4. In comparison with herbs in experimental and no experimental documents, herbs applied for weakness syndromes in experimental method are 40 kinds totally. The herbs in no experimental methods are 35 kinds. The herbs used by experimental method are 65 kinds. The common herbs for excess syndrome by no experimental method are 78 kinds. We can see comparable difference from kinds of herbs used by experimental method. In brief, there are the differences classified by each epoch in Oriental medicine for treatment. Especially one of the most important feature, the frequency in use of weakness syndrome herbs has increased more than that of excess syndrome herbs. In external documents (china) and experimental study, generally the differences of common herbs and factors have disappeared through many experimentsitudy. The classification of its factors have been fractionalized clinically. Besides, in Western medicine and Orienal medicine, vitiligo tends to be prescribed not to simple skin disease but a mental and physical disease, a whole body and an internal disease.

Design prototype is described from the stately aspect as a principle of formative art, and from the shapeable aspect of physical feature. The prototype can be a common denominator which is contained in one nation's culture, art and life, as the thing which corresponds to the daily industrial craft, architecture and art's production intention and activity with the thought and background of the culture. We have formed the design prototypes with time and space in the process which absorbs and integrates the new culture. Modern Korean design's prototype can be seen in the late Chosun. As the upper culture and sub-culture were combined, the active culture was developed. Nobody can deny that Chosun's culture and art becomes a basis of today's design and Korea's beauty. In creating the design prototype, the natural environmental factors such as topography and climate are the most important. Such natural environmental factor led the design recognition of art and craft art, as well as an architecture and indoor environment's form. Korea design produced the artisan sprite which is devoted to a moral duty and instinct as our nation's nature and emotion, and ensured the emotional process not the rational process. So, it created naturalism which accepted the material and shape. Our design prototype's path tracking as an energy of future society's new design identity, can be the important theme for our design development.

A 1-week-old, male Korean native calf with acute clinical signs of depression, mild diarrhea, ataxia, recumbency and tremor was referred to Chonbuk Veterinary Medical Center of Chonbuk National University. Vision loss and cornea edema were also observed on physical examination. The patient had been deteriorated with nystagumus, strabisumus and opisthtonus. Blood cell count test and blood biochemistry test revealed remarkable leukocytosis, and hypoalbuminemia and increased blood urea nitrogen. No remarkable findings were observed on radiography. On magnetic resonance imaging study, there were enlarge lateral, third, and forth ventricles. The cortical grey and subcortical white matter of left temporal lobe showed hypointense on T1-weighted images and hyperintense on T2-weighted images, and slightly enhanced on contrast-enhanced T1-weighted images. Escherichia coli strain was identified from cerebrospinal fluid sample. Palliative treatment was attempted but the neonatal calve was expired three days after admission. Severe multifocal fibrino-suppurative meningitis with Escherichia coli infection was confirmed histopathologically.

We reviewed 15 cases of mesothelioma of the pleura, of which three cases were localized benign form and 12 cases were malignant diffuse form. The tumors were distributed equally in both sexes, and occured most commonly in fifth to seventh decades. The history of exposure to asbestos was present in only one case. The chief complaints were mainly chest pain and dyspnea. Associated symptoms were cough, sputum, hemoptysis, weight loss, anorexia, chill. On physical examination, unilateral, decreased breathing sound was main feature. The simple chest radiograph showed masses in all localized mesotheliomas (100%) and in 2 diffuse mesotheliomas (17%). 8 cases of diffuse mesotheliomas (67%) showed unilateral pleural effusions. Pleural effusions were mainly bloody (67%), and almost all were exudates. In all localized mesotheliomas, final diagnosis was made by open thoracotomy. In diffuse mesotheliomas, final diagnosis was made by open thoracotomy in 7 cases, chest wall mass biopsy in 2 cases, thoracoscopic biopsy in 1 case, pleural biopsy in 1 case, and pleural biopsy combined with axillary lymph node biopsy in 1 case. Localized mesotheliomas were treated by simple excision with good prognosis. In diffuse mesotheliomas, surgical treatment (pleuropneumonectomy, pleurectomy), chemotherapy, or radiotherapy, alone or in combination, were used with dismal prognosis. The prognostic factors were not found due to the small number of cases, incomplete follow up, and early drop out.

Polymer substrates were fabricated by using poly (phenylene ether) as a base resin, N,N'-m-phenylenedimaleimide (PDMI) as a crosslinking agent and decabromodiphenylethane as a flame retardant. The effects of crosslinking agent and flame retardant on physical properties such as dielectric property of the substrate were investigated. Thermal curing feature of PDMI with or without an initiator was analyzed by DSC, and then, PPE-PDMI test compositions were designed based on this result. Composite sheets were cast by film coater, laminated under vacuum and pressure, and then, the changes of dielectric constant, dielectric loss, peel strength, solder heat resistance and inflammability according to increasing amount of PDMI and flame retardant were evaluated, Dielectric constant and dielectric loss showed increasing trend with increasing amount of PDMI and flame retardant, but solder heat resistance and inflammability were improved. Peel strength was obtained higher than 1 kN/m when PDMI above 10 wt% was added, but slightly decreased as the amount of flame retardant increased. From the measured gel contents, the reaction mechanism of PPE-PDMI system was deduced to the formation of network structure by crosslinking PDMI with PPE rather than the formation of semi-IPN structure. In conclusion, the polymer composite substrate materials with dielectric constant of 2.52$\sim$2.65 and dielectric loss below 0.002 at 1 GHz were obtained and they will be proper for high frequency applications.

Surface plasmon resonance (SPR) which is utilized in thin film refractometry-based sensors has been concerned on measurement of physical, chemical and biological quantities because of its high sensitivity and label-free feature. In this paper, an application of SPR to detection of alcohol content in wine and liquor was investigated. The result showed that SPR sensor had high potential to evaluate alcohol content. Nevertheless, food industry may need SPR sensor with higher sensitivity. Herein, we introduced a nano-technique into fabrication of SPR chip to enhance SPR sensitivity. Using Langmuir-Blodgett (LB) method, gold film with nano-structured surface was devised. In order to make a new SPR chip, firstly, a single layer of nano-scaled silica particles adhered to plain surface of gold film. Thereafter, gold was deposited on the template by an e-beam evaporator. Finally, the nano-structured surface with basin-like shape was obtained after removing the silica particles by sonication. In this study, two types of silica particles, or 130 nm and 300 nm, were used as template beads and sensitivity of the new SPR chip was tested with ethanol solution, respectively. Applying the new developed SPR sensor to a model food of alcoholic beverage, the sensitivity showed improvement of 95% over the conventional one.
