To achieve mine development, a large amount of data concerned with the geological structure and the ore body had to be investigated and collected through geological survey, drilling and geophysical explorations. In most previous cases, however, the data were usually analyzed two dimensionally and those results showed some limits because of their 2D presentation. Those 2D maps such as geological plane sections or longitudinal sections cause lots of difficulties in understanding the complex geological structure or the feature of ore body in a spatial way. In this study, research area was set on the abandoned Yangyang iron mine in Korea and the Sugaeng ore body within the mine was selected as the research target to design a mine haulage system for reopening. A 3D mine model of this area was tried to be constructed using a 3D modelling software, GEMS. An accurate 3D model including the ore body, the geological structure, the old underground mine drifts and the new mine drifts was constructed under the purpose of reopening of the abandoned iron mine. Especially, mine design for trackless haulage system was conducted. New inclines and drifts were planned and modelled 3 dimensionally considering the utilization of old drifts and shaft. In addition to the 3D modelling, geostatistical technique was adopted to generate a spatial distribution of the ore grade and the rock physical properties. 3D model would be able to contribute in solving problems such as evaluating ore reserves, planning the mine development and additional explorations and changing the development plans, etc.

The purpose of this study is to analyze the factors affecting the classification of the severity of contrast media side effects based on the patient's body information using artificial intelligence techniques to be used as basic data to reduce the degree of contrast medium side effects. The data used in this study were 606 examiners who had no contrast medium side effects in the past history survey among 1,235 cases of contrast medium side effects among 58,000 CT scans performed at a general hospital in Seoul. The total data is 606, of which 70% was used as a training set and the remaining 30% was used as a test set for validation. Age, BMI(Body Mass Index), GFR(Glomerular Filtration Rate), BUN(Blood Urea Nitrogen), GGT(Gamma Glutamyl Transgerase), AST(Aspartate Amino Transferase,), and ALT(Alanine Amiono Transferase) features were used as independent variables, and contrast media severity was used as a target variable. AUC(Area under curve), CA(Classification Accuracy), F1, Precision, and Recall were identified through AdaBoost, Tree, Neural network, SVM, and Random foest algorithm. AdaBoost and Random Forest show the highest evaluation index in the classification prediction algorithm. The largest factors in the predictions of all models were GFR, BMI, and GGT. It was found that the difference in the amount of contrast media injected according to renal filtration function and obesity, and the presence or absence of metabolic syndrome affected the severity of contrast medium side effects.

Two-dimensional magnetotelluric (MT) inversion algorithm using minimum support (MS) stabilizer functional was implemented in this study to enhance the contrast of inverted images. For this implementation, this study derived a formula in discrete form for creeping model updates in the least-squares linearized inversion. A spatially varying regularization parameter determination algorithm, which is known as ACB (Active Constraint Balancing), was also adopted to stabilize the inversion process when using MS stabilizer as a model constraint. Inversion experiments for a simple isolated body model show well the feature of MS stabilizer in concentrating the anomalous body compared with the second-order derivative model constraint. This study also compared MS stabilizer and the second-order derivative model constraints for a model having multiple anomalous bodies to show the applicability of the algorithm into field data.

Each and everything named fashion together with clothes were limited in the boundary of women and men's wear has been slow and narrow in changing speed compared to women's, even there are some differences in accordance time. But maintaining the basic features, men's wear in the latter 20th century has undergone diverse change in the part of materials such as various synthetic fiber, glass, metal, artificial leather and the see-through fabric able to seeing the body wearing the clothes. Therefore, the aim and definition of this study is to present the systematic framework giving help to develop men's wear design newer and more various by considering moulding of materials which existing men's wear could not show up and by grasping material trend of men's clothes in 1990s. The results of the study were summarized as follows : (1) Material containing lustering is categorized as Velvet, Silk, Lustering materials by synthetic fiber and Lustering materials by additional substance. The Velvet generally acknowledged having something to feel womanly image shows the bisexual character coexisting feature of men and women after grafting with men'fashion. The Silk was endowed the role as means of pleasure to express beyond boundary of sex breaking the existing consciousness which men should wear male clothes, not considering differences between men and women. The lustering made by synthetic fiber expressed modern sensitivity aesthetically to the suit. The lustering materials made by additional substance is seen mixed masculine character with womanly character. (2) See-through materials are acknowledged as decadence beauty caused by expanding subjective awareness in beauty. (3) Materials by the sorts of Net is categorized as Lace, Knit The Lace expression seemed to emphases the human liberation of men and women and the humanity from liberation of subjecthood. The Knit can be felt both woman's image and man's image as bisexual image, not raising only one side sex. (4) Elastic materials offered the opportunity to approve exposure in a time when exposure of men's body was not granted ethically. (5) Leather was shown as indication of social status and inferiority and expression of collective resistance against sexual stagnation of men and women.

Fashion is very superficial. However, it is expressed through the culture that is a cause of internal change and therefore its contents are defined by the cultural features. In this study, to study the aesthetic properties of the French fashion, the internal fashion contents are defined according to the cultural characteristics of France and based on the definition, the external features are investigated. The cultural characteristic was analyzed based on the reference literatures on the French culture. Based on the cultural characteristics of France, the aesthetical properties of the contemporary French fashion can be analyzed as follows: ${\cdot}$Dualism is the internal contents of the French culture with multiple sources, and it implies that opposing values such as female and male, traditionalism and modernism, simplicity and decoration are coexisting. Simplicity is pursued but decorative elements are in harmony and new phase of time is reflected while certain style has lasted for a long period of time to become a tradition. Furthermore, a rational trend combining masculinity and femininity, simultaneously exist with a trend that emphasizes feminine image. ${\cdot}$Multiculturism is a mysterious feature that has adapted the oriental or other cultural factors into the forms, patterns, colors and material of costumes. It has also been reconstructed with the French and the modern tastes. ${\cdot}$Avant-gardism is pursuing a novel aesthetic value against the former value system. It recognizes the human body as an object of figurative arts therefore emphasizes the body with geometric shapes to deny the fixed-idea, or engraft new materials and technologies to express the futuristic aspects.

Objective : Based on the immunological dysfunction in RA and the immunological feature of Clematis mandshurica Maxim. herbal acupuncture solution (CM-HAS), this study examined whether subcutaneous (s.c.) administration of CM-HAS has anti-inflammatory effects on adjuvant arthritis (AA) in the rat. Methods : Complete Freund's adjuvant was used to induce AA in rats. Secondary paw swelling of AA rats was measured, and polyarthritis index was scored. The administration of CM-HAS (2, 5, 10 mg/kg) to the Sinsu-hyul (BL 23) acupuncture point subcutaneously (s.c.) inhibited the inflammatory response and restored the weight of body and immune organs of AA rats. In this study. inhibitory effect of CM-HAS on cyclooxygenase-2 (COX-2) was evaluated. The plant material selected for this study has been used in Korean medicine for the treatment of various diseases that are considered as inflammatory in nature, e.g. asthma, arthritis, rheumatism, fever, edema, infections, snakebite and related inflammatory diseases. Results : There were significant secondary inflammatory reactions in AA rats, accompanied with the simultaneous decrease of body and immune organs weight. The administration of CM-HAS (2, 5, 10 mg/kg, s.c.) improved the above changes significantly. CM-HAS showed inhibitory activity against COX-2, which supports their traditional uses. In this study, aspirin and indomethacin were used to contrast with CM-HAS as the COX-2 inhibitors. Conclusion: The findings of this study may explain at least in part why CM-HAS has been traditionally used for the treatment of inflammatory conditions in traditional Korean and Chinese medicine.

Objective : Malaria(瘧疾) is a disease that's main symptom is paroxysm - a cyclical occurrence of sudden coldness followed by rigor and then fever. Since the introduction of the cause and mechanism of malaria(瘧疾) in the "Suwen(素問)", including Cold malaria(寒瘧), Warm malaria(溫瘧), Heat malaria(癉瘧) and Wind malaria(風瘧), there has been over 20 different kinds of malaria, each of which are introduced in multiple medical texts. Method : Through comparison between "Suwen(素問)" and other medical texts, the categories, causes and mechanisms of malaria can be analysed and organized to overview the whole feature of it. Results & Conclusion : External pathogens of malaria(瘧疾) are wind(風), cold(寒), summerheat (暑), dampness(濕), miasmic toxin(瘴), pestilence(疫), ghost(鬼). Internal pathogens of malaria(瘧疾) are dietary irregularities(飮食不節), overexertion and fatigue(勞倦), phlegm(痰), seven emotion(七情). Malaria can be categorized into four groups according to the pathological mechanism that leads to paroxysm. They are latency of disease(伏氣), external contraction(外感), internal damage(內傷), and combination of disease(合病). Malaria-Paroxysm(瘧疾發作) occurs when the three following factors collide strongly : defense qi(衛氣), latent qi(伏邪) and external pathogen(新邪). When collision of the three factors takes place in the interior(裏), the body experiences chills. When it takes place in the exterior(表), the body experiences fever. The cyclical occurrence of Malaria-Paroxysm follows the circulation of defense qi.

Objective : There was no attempt to understand Moving Energy between two kidneys(腎間動氣) and Kidney on Left & Life Gate on Right(左腎右命門) by integration progress. So I have faced to study based on two parts with concerning as clues. One is 'Life Right (左 右)' and the other is 'Between(間)'. Methods : Revealing the source of the origin, Nanjingbenyi(難經本義) is given on the basis. Take a close look at publications related to Nanjing(難經) which is about Kidney on Left & Life Gate on Right and Moving Energy between two kidneys. Take a close look at Kidney, the Life Gate and Moving Energy between two kidneys. Look see the three-dimensional uplift movement of Gi(氣). Results : In Neijing(內經) and Nanjing, the basic point of view for Kidney is the same. That is explained in line with attributes of convergence(收斂). 'Life Gate(命門)' is a term to express the divergence feature(發散機能) of kidney. Moving Energy between two kidneys is used to mean the mainspring of human body activity. The Gi in human body loses altitude turning left(左旋而下降) and gains height turning right(右旋而上升). Conclusion : Watching on functional aspect, there are two names for kidney. One is 'Kidney(腎)' which collects the losing altitude turning left and the other is 'Life Gate' which rises turning right. Moreover, the fundamental power that effectuate the uplift movement is Moving Energy between two kidneys. This kind model is a way that can be understood syntagmatically the Kidney on Left & Life Gate on Right and the Moving Energy between two kidneys without any gainsaying the original of Nanjing.

A computer program is developed in order to investigate the fluid flow and heat ransfer of a water body in a 2-D vertical rectangular coordinate. The specific purpose of this study is to obtain a physical insight of several fluid flow problems which occur in a lake and the water and wastewater treatment facility like a primary clarifier. The performance of computer program developed is successfully evaluated by the comparison of other two experimental and computational data in open literature : the first comparison is made against the numerical data associated with the cooling water discharge and the other is numerical and experimental works for the primary clarifier of Sarina City at Ontario. Further, the computer program is applied to investigate the feature of lake flow, say lake turnover, and 2-D vertical channel flow in terms of temperature, wind velocity and flow rate, etc. The computational results appear to be physically acceptable and consistent. The computer program developed in this study shows the possibility of the viable tool to figure out the flow characteristics of water reservoir.

The cultures and traditions of Asia has the roots so deep and it is the origin of inspiration. Therefore, it is easy to find a different inspiration when designing, expecially for Western designers who are seeking European tradition and its comparison. The most distinctive feature of the Asian look is non-structural and has no clear form close to the structure of the body or mathematical ratio, but is steric with 2-Dimensional planed textiles, and has a flexible, non-structural formative characteristic related to the movable body. This is base on the vision of the universe that regards the parts as the whole. From this research, generally studying about the Asian look and its non-structural formative characteristics. The study looked closely into the aesthetic value of non-structural formative characteristics formation, with basis on the large dress regulation system of the western reasoning and rationalism and mechanism. At first, my study pointed on the dressing functionalism or Neo-classism considering emotions, Anti-Western aspect observing surrealism dressing and expressionism dressing. Second, with men and women showing similar outer shape without the equivalent element such from wearing a corset, the sexism is abolished. Finally, the designers’ inner intention of art is being delivered, from the aspect that the expression of art, size and no waste of fabric shows effort of communicating with the world, giving value to the possibility of continuance.
