The purpose of this study was to seek the means of enlarging the application of Saek-dong to fashion products by surveying and analysing the recognition and image of Saek-dong in college students. As a research procedure, the bibliographical survey on the meaning and history of Saek-dong was preceded in this study, and the students were examined on the recognition and image of Saek-dong through the questionnaires. The female students were more acquiesced with the Saek-dong and Saek-dong clothing than the male students. And the students thought that the Saek-dong was our original and traditional clothing because it was worn by our ancestors from the earliest years. The word Saek-dong reminded them of red, yellow, blue, green, white and red-brown colors in order of appearance. The most familiar color-arrange to them was red+yellow+dark-brown+green+blue, and the blue, purple, green, red, white color was thought as manly Saek-dong colors and the yellow, red, dark-brown, pink, white was regarded as feminine Saek-dong colors. Saek-dong was primarily associated with the image of Saek-dong clothing and most of the students expressed their feeling about the Saek-dong as 'cute.' Most of the students responded that the practical Hanbok was best illustrated as the most applied clothing of Saek-dong and that the attempt to apply the color and pattern of Saek-dong to other modern artistic products was likely to damage the worth of traditional Saek-dong. When it comes to the matter of applying the design of Saek-dong to the fashion products, male students thought that it could be best applied to the shirts, while female students thought that the design of Saek-dong could best be applied to the personal ornaments.

The purpose of this paper is to present the manufacturing defect and damage pattern of a 3 phase 22.9/3.3kV oil immersed transformer, as well as to present an objective basis for the prevention of a similar accident and to secure data for the settlement of PL related disputes. It was found that in order to prevent the occurrence of accidents to transformers, insulating oil analysis, thermal image measurement, and corona discharge diagnosis, etc., were performed by establishing relevant regulation. The result of analysis performed on the external appearance of a transformer to which an accident occurred, the internal insulation resistance and protection system, etc., showed that most of the analysis items were judged to be acceptable. However, it was found that the insulation characteristics between the primary winding and the enclosure, those between the ground and the secondary winding, and those between the primary and secondary windings were inappropriate due to an insulating oil leak caused by damage to the pressure relief valve. From the analysis of the acidity values measured over the past 5 years, it is thought that an increase in carbon dioxide (CO2) caused an increase in the temperature inside the transformer and the increase in the ethylene gas increased the possibility of ignition. Even though 17 years have passed since the transformer was installed, it was found that the system's design, manufacture, maintenance and management have been performed well and the insulating paper was in good condition, and that there was no trace of public access or vandalism. However, in the case of transformers to which accidents have occurred, a melted area between the upper and the intermediate bobbins of the W-phase secondary winding as well as between its intermediate and lower bobbins. It can be seen that a V-pattern was formed at the carbonized area of the transformer and that the depth of the carbonization is deeper at the upper side than the lower side. In addition, it was found that physical bending and deformation occurred inside the secondary winding due to non-uniform pressure while performing transformer winding work. Therefore, since it is obvious that the accident occurred due to a manufacturing defect (winding work defect), it is thought that the manufacturer of the transformer is responsible for the accident and that it is lawful for the manufacture to investigate and prove the concrete cause of the accident according to the Product Liability Law (PLL).

During these days of new understanding, western medicine has developed remarkably and a revaluation of traditional medicine has been achieved. This appears to have resulted from the sound criticisms of what western medicine has achieved up to now; excessive subdivisions of clinical medicine, severe toxicity of chemical drugs, lack of understanding about patients complaints which cannot be understood objectively, and etc. It is thought that the role of traditional medicine will be more important in the future than it is now. Someone said that the research methods of traditional medicine depends on the way of experimental science too much. That there was no consideration of a system for traditional medicine and the critic also went so far as to assert that in some cases the characteristics of eastern ideas is to permit irrationalism itself. In view of this thinking, the term traditional medicine seems to have been used somewhat too vaguely. However, traditional medicine is a medical treatment which has existed since before the appearance of modern medicine and it was formed from a traditional culture with a long history. One form of traditional medicine, oriental medicine based upon ancient Chinese medicine, was received in such countries as Korea, Japan, Thailand, Vietnam, Tibet, and Mongolia. Oriental medicine then developed in accordance with its own environment, race, national characteristics, and history. Although there are some simultaneous differences between them, three nations in Eastern Asia; Korea, Japan, and China, have especially similar features in their clinical prescriptions and medical literature. These three nations are trying to understand each others unique traditional medicines through numerous exchanges. Even though many differences in their ways of studying have developed over history exist, recent academic discussions have been made to explore new ways into oriental medicine. Therefore a comparative study of oriental medicine has gradually been thought to be more important. In Korea the formation of a new future-oriented paradigm for oriental medicine is being demanded. The purpose of the new paradigm is to create a new recognition of traditional culture which creates an understanding of oriental medicine to replace the diminished understanding of oriental medicine that was brought about by the self-denial of traditional culture in modem history and cultural collisions between oriental and occidental points of view. Therefore, to make a new paradigm for oriental medicine which is suitable for these days, and fortifies the merit of oriental medicine while compensating its defects, the author has compared the characteristics of oriental medicines in Korea, Japan, and China. The conclusions of this research are as follows: 1. The fundamental differences of the traditional medicines of these three nations are caused by the differences in the systems of Naekyung and Sanghannon. 2. The pattern-identification of illnesses is generally divided into two categories; the pattern identification of Zang-Fu and the pattern identification of prescription. 3. There are many differences in the definition of terms, such as Yin and Yang, Deficiency and Excess, and etc. 4. Chinese traditional medicine has some new concepts about pattern identification and epidemic febrile disease. 5. Japanese traditional medicine has some characteristics about pattern identification of the whole bodys condition and signs of abdominal palpation. 6. In terms of the effects of herbal drugs, Chinese traditional medicine attaches great importance to the experiential efficacy of the herb, and Japanese traditional medicine is taking a serious view of the effects of experimental medical actions.

Classification of human thought is an emerging research field that may allow us to understand human brain functions and further develop advanced brain-computer interface (BCI) systems. In the present study, we introduce a new approach to classify various mental states from noninvasive electrophysiological recordings of human brain activity. We utilized the full spatial and spectral information contained in the electroencephalography (EEG) signals recorded while a subject is performing a specific mental task. For this, the EEG data were converted into a 2D spatiospectral pattern map, of which each element was filled with 1, 0, and -1 reflecting the degrees of event-related synchronization (ERS) and event-related desynchronization (ERD). We evaluated the similarity between a current (input) 2D pattern map and the template pattern maps (database), by taking the inner-product of pattern matrices. Then, the current 2D pattern map was assigned to a class that demonstrated the highest similarity value. For the verification of our approach, eight participants took part in the present study; their EEG data were recorded while they performed four different cognitive imagery tasks. Consistent ERS/ERD patterns were observed more frequently between trials in the same class than those in different classes, indicating that these spatiospectral pattern maps could be used to classify different mental states. The classification accuracy was evaluated for each participant from both the proposed approach and a conventional mental state classification method based on the inter-hemispheric spectral power asymmetry, using the leave-one-out cross-validation (LOOCV). An average accuracy of 68.13% (${\pm}9.64%$) was attained for the proposed method; whereas an average accuracy of 57% (${\pm}5.68%$) was attained for the conventional method (significance was assessed by the one-tail paired $t$-test, $p$ < 0.01), showing that the proposed simple classification approach might be one of the promising methods in discriminating various mental states.

Analyzed the subject of ‘To heart' meridian system(向心服系), and 'Circulating' meridian system(備環服系), and considered relativity between the circulating pattern of the channels, the collaterals and the circulating distinction YoungGi (營氣), WiGi(衛氣). The subject of 'To heart' meridian system is WiGi, and this system is similiar to the moving pattern of the fifteen major collaterals(十五絡服). The subject of 'Circulating' meridian system is YoungGi, and this system is same with the moving pattern of the twelve regular channels(十二經脈). YoungGi and WiGi have the same origin, and they are intrinsic one thing with functional ambivalency. It is WiGi, the subject of the movement of Collateral, because it is identical the moving pattern of Collaterals(絡服) and that of WiGi as the subject of the movement of Collateral. It is YoungGi, the subject of movement of Channel because it is identical the moving pattern of Channels(經服) and that of YoungGi. It can be defined that Wigi as the subject of the movement of Collateral, also YoungGi as the subject of movement of Channel, but that is from i 염 function and action, there's no need to be separated within the framework of going through Meridian. YoungSuBosa(迎隨補鴻) in acupuncture, defines its basis not only on the moving direction of YoungGi, but on combinated difference between the directions, moments, and sex. Until now it is under discussion the rights and wrongs, It's not contradictory concept between two basis of YoungSuBoSa, from the thought the distinct movement of WiGi and the circulation pattern of Collaterals have no specified directions.

Mask manufacturing is a high COC and COO process in developing of semiconductor devices, because of the mass production tool with high resolution. Direct writing has been thought to be one of the patterning method to cope with development or small-lot production of the device. This study focused on the development of the direct, mastless patterning process using stereolithography tool for the easy and convenient application to micro and miso scale products. Experiments are utilized by three dimensional CAD/CAM as a mask and photo-curable resin as a photo-resist in a conventional stereo-lithography apparatus. Results show that the resolution of the pattern was achieved about 300 micron because of complexity of SLA apparatus settings, inspite of 100 micro of inherent resolution. This paper concludes that photo resist and laser spot diameter should be adjusted to get finer patterns and the proposed method is significantly feasible to mastless and low cost patterning with micro and miso scale.

Jang Gyung Ak thought the Yang Gi was the basis of life. This is why he said doctors should emphasize on preserving Yang Gi. Before his emphasis on Yang Gi he had to study and criticize the medical concept of HaGan, DanGye and DongWon. By criticizing and overcoming their medical concept's fallacy and limitations, he made his own medicine. JangGyungAk found the importance of YangGi in the theory of changes. In the "the Book of Changes" it is said the rising movement of YangGi is expressed by recipricals and propels heaven and earth, yin and yang to change. The phenomenon of life is also a reciprocal and is lead by YangGi, and so medicine should value Yang Gi. Because the phenomenon of life is lead by this Yang Gi, it is right to base changes of diseases and organize pattern identification. The pattern identification JangGyungAk presented as two Gang six Byun sets its base on YangGi.

In this paper, we compared and analyzed the power load patterns of dormitory buildings and office buildings to use them as basic data (demand analysis and capacity design) for the design and operation of microgrids for multi-use facilities, and the following conclusions were got. During the daytime on regular weekdays, the power consumption load pattern of office buildings was relatively large at 264.0~332.3 kWh, and during the evening hours, the power consumption load pattern of dormitory buildings was relatively large at 233.0~258.3 kWh. In the case of vacation, during the daytime on weekdays, the power consumption load pattern of office buildings was relatively large at 279.1~407.4 kWh, and in the evening, the power consumption load pattern of dormitory buildings was relatively high at 280.1~394.1 kWh. During the daytime on regular weekends, the power consumption of dormitory-type buildings was relatively high at 133.5~201.6 kWh, and it was found that the power consumption of dormitory-type buildings appeared relatively high at 187.5~252.1 kWh. During a vacation in the daytime on weekends, the power consumption of dormitory-type buildings was found to be 186.5 kWh~ and 218.6 kWh. The increase in power consumption during a vacation (December-February) compared to normal (April-June) was thought to be due to an increase in electricity demand, and the reason for the higher power consumption in dormitory buildings during the vacation was due to reduced working hours in office buildings.

In the present investigation, we are newly developing a new forming process which can fabricate micro patterns on large-area polymeric substrates for high speed mass production. The key idea of the new process is to pressurize multiple vacuum-packed substrate-mold stacks above the glass transition temperature ($T_g$) of the polymeric substrates. The new process is thought to be promising micro-pattern fabrication technique in three aspects; firstly, isostatic pressing ensures the uniform micro-pattern replicating condition regardless of the substrate area. Secondly, the control of forming condition such as temperature and pressure can realize well-defined process condition exploited in the conventional hot embossing research field. Thirdly, multiple substrates can be patterned at the same time. A prototype forming machine for the new process was developed with the design consideration realizing the present idea. With a developed machine, micro prismatic array patterns with 50 um in size were successfully made on the $380{\times}300{\times}6\;mm$ PMMA plate.
