More diversified and strengthened safety regulations require higher safety vehicle with less weight. The structural foam can play a role for restraining section distortion of main body members undergoing bending collapse at vehicle crash. In this study, using structural foam modeling technology, validated in previous work, the bending collapse characteristics were evaluated for two types of circular and actual vehicle body frame sections. With changing the foam filling method, outer panel thickness and section shape, load carrying capability and absorbed energy were observed. The results indicate valuable design strategy for effectively elevating bending collapse performance of body members with foam filled.

Vortical structures are investigated numerically for both cold and combusting flows from a two-dimensional bluff-body burner in the transitional flow regime from steady to unsteady state. The Reynolds number of the central fuel flow is varied from 10 to 230 at a fixed air Reynolds number of 400. The flame sheet model of infinite chemical reaction and unit Lewis number are assumed in the simulation. The temperature dependence of the viscosity and diffusivity of the gas mixture is also considered. The vortex shedding is observed depending on the fuel flow. For cold flow, four different types of vortical structure are identified. However, for combusting flow of methane-air system the vortical structures change significantly due to a large amount of heat release during the combustion process, in contract to cold flow.

The textile designs expressed in contempor-ary fashion are studied in this paper. The dec-orative paintings have been encouraged to be-ing adapted in textile designs for apparel as a motif of the surface design to promote the ar-tistic atmosphere in it. Adopting paintings in textile design through the method of printing is valid to improve the fashion in several reasons as follow : First the printed paintings on the fabrics could be possible to contribute individuality and creativity to the fashion im-proving the quality of textile design and the taste of the consumer as well, Second the limitted types of the clothing construction for preparing the proper space to reveal a paintings is needed on the costume The simple clothing types of loose from the body or fitted to the body are easy to adopt and to recreat the paintings on the apparel. Third the paintings which have been favored in use for the textile design are mostly derived from the abstract arts rather than re-alistic paintings for its decorative traits. Fourth a proposal to adapt the other genre of the art could be encouraged to enrich the field of textile and fashion design. Fifth aquisition of the individuality and the creativity in fashion design to differenciate in international market could be obtained through the adaption of Korean paintings which is ap-preciated with Korean sentiment and mind. This would be one of the essential and advis-able ways for designers to solve the problems which have been consistently pusuing in the area of Korean industrial design to find the Korean design model.

Objectives : There exists a number of books that deal with curing diseases with foods. This includes Shennongbencaojing from Han Dynasty era, Zanyin's Shiloaoxingan and Mengxi's Shilaobencao from Tang Dynasty era, Husihui's Yinshanzhengyao from Won Dynasty era, and Feiboxiong's Sikgamboncho from Qing Dynasty era. This paper aims to delve into the food treatment revealed in Sikgamboncho, which is the latest book in the preceeding list, and studied its differences when compared to other medical books that deal with food treatment methods. Methods : The format and contents of Feiboxiong's Sikgamboncho were studied. For its format, Shilaoaoxingan, Yinshanzhengyao, Shikryochanyo, and Donguibogam were used to compare their formats with that of Sikgamboncho in order to discern the unique characteristics found in the book. For its contents, the paper studied food ingredients and food treatment separately, and then studied the historical significance of Feiboxiong's Sikgamboncho. Results : Sikgamboncho categorizes 12 types of grain, 22 types of vegetables, 7 types of cucumis calyx, 27 types of fruit, 9 types of flavor, 4 types of bird, 4 types of animal, 10 types of fish with scales, 4 types of carapace, and 2 types of worm. The book explains each ingredient's harvest period, its nature, potency, and taboos. The food treatment section explains 74 types of treatments that are divided between the wind, cold, summer heat, dampness, dryness category and the qi, blood phlegm, deficiency, and excess category. Each treatment contains its potency and recipe. Conclusions : Feiboxiong underlined the importance of ingredient through placing significance even to the order of ingredients. Out of the total 74 food treatments, 25 treatments were dedicated to deal with weakness. Feiboxiong attempted to prevent human body from becoming weak, which reflects his emphasis on the importance of food and wellness.

The body composition of an ancient roofing tiles excavated from Chonnam province has been investigated by X-ray diffraction, and inductively coupled plasma spectroscopy. Ancient roofing tiles were excavated at ancient mountain fortress and kiln sites. The body composition of roofing tiles was different according to the excavated sites. The mineral component of roofing tiles were grouped in the five types and chemical composition was different according to the excavated areas. It is presumed that the body of roofing tiles used low-grade raw materials containing $Fe_2O_3$ 4-10%. The trace element composition of the roofing tiles were different, and it might be all ret1ection of different geological characteristics. The characteristic element of rooting tiles was vanadium element of the analyzed 20 trace elements. By $SiO_2-V$ distribution diagram types, roofing tiles excavated from the Geomdan mountain fortress at Sunchon, kiln site in Yeochon, Gorak and Cheoksan mountain fortress at Yeosu were grouped into the same excavated site.

PURPOSE. The purpose of this study was to evaluate the occurrence of displacement while tightening the screw of scan bodies, which were compared according to the material type. MATERIALS AND METHODS. Three types of scan bodies whose base regions were made up of polyether ether ketone (PEEK) material [Straumann Group, Dentium Group, and Myfit (PEEK) Group] and another scan body whose base region was made up of titanium material [Myfit (Metal) Group] were used (15 per group). The reference model was fabricated by aligning the scan body library on the central axis of the implant, and moving this position by the resin model. The screws of the scan bodies were tightened to the implant fixture with torques of 5 Ncm, 10 Ncm, and a hand tightening torque. After the application of the torque, the scan bodies were scanned using a laboratory scanner. To evaluate the vertical, horizontal, and 3-dimensional (3D) displacements, a 3D inspection software program was used. To examine the difference among groups, one-way analysis of variance and Tukey's HSD post hoc test were used (α=.05). RESULTS. There were significant differences in 3D, vertical, and horizontal displacements among the different types of scan bodies (P<.001). There was a significantly lower displacement in the Straumann group than in the Myfit (PEEK) and Dentium groups (P<.05). CONCLUSION. The horizontal displacement in all groups was less than 10 ㎛. With the hand tightening torque, a high vertical displacement of over 100 ㎛ occurred in PEEK scan bodies (Myfit and Dentium). Therefore, it is recommended to apply a tightening torque of 5 Ncm instead of a hand tightening torque.

Power is the driving force of society, and the generation of power is inevitable. as long as society is rganized hierarchically. According to Michael Foucault's discourse modern power operates as a mechanism of 'panopticon', a system that monitors the 'body' of man through discipline. Moreover. fashion as acts as a symbol of beauty that continues to co-exist with power for the purpose of exposing status and authority, and for displaying the trends within a culture. So, it is necessary to study fashion design according to the changing power structure that exists in society. The aim of this study is to suggest types of creative fashion design process by visualizing the Foucault's power discourse through the image associative action. The four types of creative fashion design that have been drawn by visualizing Foucault's power discourse are as follow: disciplinary power, imprisonment power and knowledge power. The first type of fashion design method is to emphasize the shoulder by using shoulder pads, strings, tabs, and incisions in the clothing. The second method is to expose the body by using see-through material and manipulating its composition to expose the body. Third method is to borrowing elements of underwear. Fourth method is to utilize patterns that represent power, such as weapons, bones, blood, muscles, skulls, and various human imagesin the clothing. Through this study we expect to utilize creative fashion design to visualize concepts of the humanities, such as philosophical discourse.

The purpose of this study was to develop jacket patterns that could fit well for women in their 20s with turtle neck syndrome body shape and to present a pattern drafting method. As a research method, an educational pattern was chosen through a preliminary experiment. Fit problems of the educational pattern were derived by wearing it on a virtual model with a turtle neck syndrome body type for each neck angle. Based on the three types of experimental patterns developed by supplementing these problems, a development pattern drafting method was developed for each neck angle. Three development patterns were compared and evaluated with the educational pattern using 3D virtual fitting. Fit problems of the educational pattern included: 1) insufficient ease amounts for hip, hem, bicep, elbow, and sleeve hem circumference; 2) horizontal items could not be leveled due to insufficient back length; 3) the shoulder line went backwards; and 4) the front center line did not form a vertical line. To solve these problems, an experimental pattern was developed by increasing the insufficient ease amount, increasing the insufficient back length, and correcting the position of the shoulder line. Measurements that differed in the pattern drafting method of the three types of development patterns by neck angle were positions of back center line and back neck point, front length, and front neck width. Through appearance evaluation of the development pattern and educational pattern by neck angle, the development pattern was highly evaluated, indicating that problems of the educational pattern were improved.

Purpose: The purpose of this study is to find out the patterns of teenage girls who is easy to suffer from dysmenorrhea with the Inbody test results by Sasang constitutions. Methods: The data from the 1681 participants were collected using a structured menstrual history questionnaire. Based on the survey responses, we had 97 adolescents with menstrual disorder as the test group and 97 adolescents without menstrual disorder as the control group. The clinical trials subjects were asked to respond to another questionnaire for identifying their constitutional types and undergo Inbody test. Results: The result of a comparison of the test and control groups showed that there' no relevance to the body fat mass and body fat percentage with menstrual irregularities. The lesser yang person with menstrual irregularities was no relevance to the body fat percentage. The greater yin person with menstrual irregularities was especially lacking in body fat mass and body fat percentage. The lesser yin person with menstrual irregularities was poor in body fat mass. Conclusions: As for study, female high school students with menstrual disorders have nothing to do with muscle mass. Body fats shortage could pose problems. According to the study, Taeumin female high school students usually needed to higher body fat than a general standard. It seems to be needed more body fat and weight than modern standards in period of poor sexuality for having a normal menorrhea especially Taeumin. It will take some continuing study that BMI standards should be changed or not on the Sasang constitutions.
