The purpose of this study is to analyze on the fashion collection of Hussein Chalayan who has changed the concept of fashion design in the 21st century and has pioneered in the new vision of fashion. This study will give a new perspective and perception of fashion as a conceptual and ideological art. The conclusions of this study are as follows. First, Hussein Chalayan's multicultural ideas and interdisciplinary approaches which based in national speciality are the unique elements in his works. Second, Hussein Chalayan intends to present his works as an expression of conception. He has expressed the clothes which speaks the form of nature, symbolizes the combination of culture, visualizes time and space and investigates the existence of human being. Third, Hussein Chalayan has asked an endless question about existence of the human being. Furthermore, He has put a question about the relationship between time, space, history, nature and the human being. His trial to visualize the metaphysical conception of 'ego' and 'self' through his works of art makes him as the designer who represents the 21st century. Forth, Hussein Chalayan pursues the communication between the human being and the world. His works is made for human being and makes the human life as valuable thing. Because the clothes is completed when the human wears it, it can not exist without the relationship of human being. Fifth, Hussein Chalayan makes a various attempt to combine with different artistic field. Fashion has developed to new direction with diverse trial and combination beyond fashion field and this has to be a direction in the 21st century fashion. Fashion is not just making clothes, but accepting and delivering the history and culture, expressing and communicating empathy, and combining the different fields harmoniously.

Objectives : To research the trend of the study related to Chuna(推拿) and to establish the direction of further studies into the Chuna(推拿). Methods : We reviewed and analyzed all theses published by Korean research institution. And these theses were classified by research institutions, published year, field of study, subject, research methods, thesis types, illness and symptoms. Results : The following results were obtained in this study. 1. Classified by the major field of study, oriental medicine accounted for 59 papers, followed by 18 in physical education and 2 in the science of nursing and medicine. 2. Upon classifying theses according to research method and thesis types, research related to clinical trial accounted for nearly half of all theses. It was followed by consideration of documents. 3. After 1998 deals with the effects of the Chuna on variable illnesses such as: ossified posterior longitudinal ligament, chronic coccyalgia, entrapment neuropathy, low birth weight infant, Bell's palsy, stress incontinence, paramenia, Parkinson disease, Bertolloti syndrom, TMJ (because of scoliosis) etc. 4. Two most widely cured illnesses using the Chuna therapy are scoliosis and HNP of L-spine. However, when considering the fact that several clinical tests and casuistics did not include research into Lumbago (including HNP of L-spine), it can be concluded that most of the Chuna therapies have been concentrated on Lumbago. Conclusion : As it can be seen in the above results, the possibility of curing illness through Chuna and the usefulness of Chuna have been shown factually and clinically through various consideration of documents, clinical trial & casuistics. Based upon such facts, it is regarded that further scientific research along with additional clinical approaches involving the Chuna should be performed.

The aim of this study is to investigate the characteristics on the profile of local ice load acting on side shell of port side in bow part due to broken ice during icebreaking of ships in ice covered waters. The first Korean icebreaking research vessel 'ARAON' had a sea ice field trial in the Arctic Sea during early August, 2010, and the signals due to local ice impact measured from several strain gauges installed at bow part were gathered. It is known that these data with structural response characteristics due to local ice impact have some different characteristics with a typical hydraulic impact pressure - time history. In this study, the time history on the measured signals was analyzed and the characteristic values were presented using non-dimensional parameters.

This study aimed to evaluate the inhalation resistance(IR) and fiber structure of disposable masks when exposed to repeated heating and ultraviolet(UV) sterilization. The experiments consisted of a lab-scale and a field test. For the lab-scale test, KF94 and N95 masks were selected and a trial was composed of three repetitions of an 80-min sterilization. For the field test, a subject participated over four days, of which a KF94 was worn without sterilization, and the same trial was conducted during the next four days with daily sterilization. The results showed that the IR of the KF94 mask(9.5 Pa) gradually increased according to the sterilization up to the second repetition(15.6 Pa) but decreased at the third treatment(9.7 Pa). However, the N95 mask did not showany tendency of IR during the repetitions. Microscope photos showed several warped or blackened fibers in the stiffener layer after the repeated sterilization. After wearing a KF94 mask for four consecutive days, its IR decreased until the three days but increased the fourth day, whereas another KF94 mask with sterilization showed an increase in IR for the four days. In the microscope-photos after the consecutive four days, outside fibers and stiffener layers were warped or became less dense. In summary, the IR of the KF94 mask slightly increased through the three~four rounds of heating and UV sterilizations, but the fiber structures were not significantly deformed by the repeated sterilization. To reduce discarded mask waste, the repeated sterilization of masks can be recommended.

The binder for hot mix type colored pavement must have the same physical qualities as the straight asphalt cement, but its color must not be dark-brown. We developed a kind of synthetic resin binder with light yellow color and confirmed its possibility as a binder for colored pavement through the several comparison tests between the straight asphalt cement concrete mixture and the mixture of binder and aggregate for colored pavement. For the pigment, it has been assured through tests that home products have the possiblities to be used. The binder has come to the stage of practical use through the trial mixing by asphalt mixing plant and the trial field placing. The mixing operation and the paving method of colored mixture are same as normal asphalt concrete mixture, but the quantity of pigment replaces that of mineral filler. The required content of pigment is decided by the trial mixing with other materials to be used.

A new Sikbangpoong(Peucedanum japonicum Thunberg) variety, 'Sikbangpoog 1', was developed through a pure line selection at the Kyougpuk Provincial RDA during the period of 1990 to 1995. The variety was characterized to have higher stem height, leaf number and seed production, and larger root diameter compared with the check variety of Bonghwa Sikbangpoong but plant height of 'Siknagpoong 1' was similar to that of the check variety and it was also more tolerant to water and heat stress. Root color of 'Sikbangpoong 1' was yellowish brown and root shape of the variety was straight and conical. The root yields of Sikbangpoong 1 in yield trial, regional adaptation trial and farmer's field trial were always 10-28% higher than those of the check variety.

Two trial products of monogranular compound fertilizer for red pepper under vinyl mulching cultivatin were made using the principal sources of urea, diammonium phosphate and muriate of potash in combination with fillers of treated human wastes (product I) and zeolite (Product II). A field experiment was carried out to evaluate their effects on red pepper and the results obtained were as follows. Red pepper plant growth and total red fruit yields in the trial products of one time basal application were better and higher than those of NPK split application of contrl plot. The increases of yield in the trial products might be due to steady supply of nutrients for the entire growing period. Therefore, one time basal dressing of a developed monogranular compound fertilizer for red pepper was applicable under vinyl mulching cultivation.

Use of herbicides in Korean agriculture has increased rapidly in recent years accompanying with ever-increasing pressure of farm labor shortage. Herbicides occupied already the second place in the rank of pesticides consumption in 1977. The agricultural experiment stations have carried out over 50 trials of chemical weed control each year since 1968. These research works and registration trials contributed much to the present wide use of herbicides. The pesticide management act amended in 1977 requires reevaluation of pesticides for their efficacy every 5 year-term. However, the development of sound weed control program and recommendations has been hempered very much by the lack of qualified workers of weed control research in agricultural experiment stations and in the institute for pesticide registration trial. Critical review of the past research works on herbicide evaluation and the present status indicates strong need for 1) the characterization of the nature of local and national weed problem, 2) the improvement of ability of the staffs in charge of weed control research through appropriate training on the basics and experimental techniques, and 3) organization and activities of weed control research committee. Furthermore, the present article attempts to clarify commonly misled points in the establishment of herbicide evaluation plan, in the design and execution of field trials, and in the assessment of trial results of the past works from the viewpoint of the basic principles with some case studies for resolution of specific enigmas.

Materials used for the inks in the printing industry is an important material following the paper. The composition of the ink is pigment and organic solvents. However, Ink is used in a variety of chemicals, they are classified as non-green. Therefore, rosin-modified phenolics manufactured by the reaction of phenol and formaldehyde can take the place of eco-phenol free resin and by experiment density, gloss, trapping, contrast and dot gain of printing has been studied as printability. The result of study can support that the properties of printing using eco-phenol free resin such as density, gloss, contrast and trapping is similar to existing ink. In the part of dot gain, the result is excellent. So we were thought to be able to improve some characteristics such as dispersion of black ink, that will be possible for the field applicability.

A net-shape forming of small and complex-shaped metal parts by metal injection molding (MIM) has economic advantages in mass production, especially for STS 316L valve fitting. STS 316L offers excellent corrosion resistance, but it has poor machinability, which is a limitation in using it for a cost-effective production where both forging and machining are employed. Simulation and experimental analysis were performed to develop a MIM STS 316L 90° elbow fitting minimizing trial and error. A Taguchi method was used to determine which input parameter was the most sensitive to possible defects (e.g. sink mark depth) during the injection molding. The final prototype was successfully built. The results indicate that the simulation tool can be used during the design process to minimize trial and error, but the final adjustment of parameters based on field experience is essential.
