Reaching up the present from the past, the design was reflected in our life, thereby having brought about great development in the aesthetic harmony or functional part. In the present era, it is advancing in order to seek for the better direction without being satisfied with formativeness. What comes to represent it is UX design, namely, user-experience design. If a user has confusion in using product or environmental facilities, or if a user needs to utilize by analyzing function, this cannot help being inconvenient. Only what a user's behavior is caused by which the cognitive and sensitive attributes interact without inconvenience can be said to be design for a user. Given explaining easily, UX implies to design and develop the designed product or space from the position of a client who uses. Also, it also implies to offer service of being satisfied. For one example, a work can be said that distributes logo to the upper part of web site. That is because of allowing client to be much confused if logo is distributed to the different position. The designed web site in consideration of user's position is developed much now. However, it is the real situation of being still much insufficient in the public facilities that have UX characteristics amid the living environment. There is great interest in UX of the public facilities. However, there are many cases of facing mostly for the first time. The understanding level is thought to be much different. This study examines about a concept of UX design, and about UX design, which considered from the user's position, and analyzes a case. Thus, the aim is to suggest good directivity in designing by efficiently approaching UX that can be difficult theoretically.

An analysis of biosignal and performance data collected during driving has increasingly employed in research to explore a human-vehicle interface design for better safety and comfort. The present study developed a protocol and a system to effectively analyze biosignal and driving performance measurements in various driving conditions. Electrocardiogram (ECG), respiration rate (RR), and skin conductance level (SCL) were selected for biosignal analysis in the study. A data processing and analysis protocol was established based on a comprehensive review of related literature. Then, the established analysis protocol was implemented to a computerized system so that immense data of biosignal and driving performance can be analyzed with ease, efficiency, and effectiveness for an individual and/or a group of individuals of interest. The developed analysis system would be of use to examine the effects of driving conditions to cognitive workload and driving performance.

An American ginseng(Panax quillquefolium L) industry has emerged in British Columbia, Canada over the past ten years. Interest has grown very rapidly and with this development, attention is now moving away from field production issues and emphasis is being directed to enhancements in ginseng storage, drying and processing. There is a dearth of knowledge on these aspects even though they are crucial to international competitiveness. Enhancement dicatates the application of a systems approach to optimizing the harvest and post - harvest production system(crop digging, pre - washing cold storage. washing, drying and post - drying storage). Research in British Columbia to date has focussed on drying and storage issues and has resulted in the design of an enhanced commercial drying system. The role of dryer management, loading rates, airflow rates and pre - drying cold storage on American ginseng root drying rates and root quality were examined. From the dryer management experiments, there are distinct advantages to size sorting root to yield optimum drying rates. If unsorted root is used, efficiency is increased if the trays are systematically rotated. Loading rate experiments illustrate that increasing rates above those currently used in commercial dryers are possible without any sacrifice in quality. This has significant implications for commercial drying. Pre - drying cold storage is a most significant tool for managing drying operations. Over a period of six weeks, no discernable decrease in quality was found as a consequence of cold storage. Further, the moisture loss and the associated root surface changes(loss of surface soil in storage for example) provide new challenges for root quality management. Continued research and technological innovation will be crucial in addressing the demanding challenges of the future.

Background: Adipocyte-macrophage communication plays a critical role regulating white adipose tissue (WAT) inflammatory gene expression. Because WAT inflammation contributes to the development of metabolic diseases, there is significant interest in understanding how exogenous compounds regulate the adipocyte-macrophage crosstalk. An aqueous (AQ) extract of North American (NA) ginseng (Panax quinquefolius) was previously shown to have strong inflammo-regulatory properties in adipocytes. This study examined whether different ginseng extracts influence adipocyte-macrophage crosstalk, as well as WAT inflammatory gene expression. Methods: The effects of AQ and ethanol (EtOH) ginseng extracts ($5{\mu}g/mL$) on adipocyte and macrophage inflammatory gene expression were studied in 3T3-L1 and RAW264.7 cells, respectively, using real-time reverse transcription polymerase chain reaction. Adipose tissue organ culture was also used to examine the effects of ginseng extracts on epididymal WAT (EWAT) and inguinal subcutaneous WAT (SWAT) inflammatory gene expression. Results: The AQ extract caused significant increases in the expression of common inflammatory genes (e.g., Mcp1, Ccl5, Tnf-${\alpha}$, Nos2) in both cell types. Culturing adipocytes in media from macrophages treated with the AQ extract, and vice versa, also induced inflammatory gene expression. Adipocyte Ppar-${\gamma}$ expression was reduced with the AQ extract. The AQ extract strongly induced inflammatory gene expression in EWAT, but not in SWAT. The EtOH extract had no effect on inflammatory gene expression in either both cell types or WAT. Conclusion: These findings provide important new insights into the inflammo-regulatory role of NA ginseng in WAT.

This study investigated the design practice model based on the creative fashion designer's methodology in fashion education. 'The Design Cycle' was the criterion used to analyze the design method of Demna Gvasalia who is one of the outstanding contemporary designers. After that, this study's practice model was then developed and experimented to verify its effectiveness in design practice as based on Gvasalia's method where ready-to-wear products were firstly dissembled then re-constructed with new designs created based on re-constructed results. To test its effectiveness, a student oriented design workshop was held to extract design results through the practice model; in addition, the students also conducted a survey to evaluate the effectiveness of the method. According to the self-evaluation result, the participants generally accept the design efficiency through the distinctive process. An evaluation by three fashion experts was also conducted. Experts assessed that the model is recommendable for seniors having knowledges on 'Construction', it is appropriate to deal with the trickled-down copying trend that could promote student interest and generate separate results according to different visions. Therefore, it could be accepted that the applicability of this study's practice model was confirmed.

Recently, strong interest in the well-being and healthy food trends lead a spreading of rice processing products such as rice noodles, rice breads, and rice cakes. However, most of rice varieties developed in Korea showed very limited processing properties in processing of noodles compare to that of wheat flour. Moreover, low competitiveness as a raw processing materials due to high price give poor evaluations for rice noodles processing. To cope those barriers, 'Saemimyeon' a Tongil type high yielding variety with a high amylose contents was developed in RDA. 'Saemimyeon' showed about 10~32 % of increase in yield as 7.08MT/ha and 26.7% of high amylose contents together with easy grinding property of 65.7% of high chalkiness ratio. The both of milled as well as brown rice of 'Saemimyeon' were well fit for processing properties in rice pasta where the contents of rice flour for rice pasta was 99% (1% of Tapioka starch was intermixed in to the rice flour). A spaghetti type for wet noodles and macaroni type for dry noodles were developed, respectively. Each of pasta were showed relatively more or less an equal quality and panel test compare to that of durum wheat pasta products. Finally, rice pasta products could suggest an alternative idea for a new rice processing items where rice noodles market was stagnant.

The purpose of this study was to provide information about the development of curricula geared toward improving the oral health of college students and of oral-health education programs in an effort to teach college students to be knowledgeable about oral health throughout their lives. The subjects in this study were 455 students at three different colleges in Gyeonggi province, on whom a survey was conducted. As for the basic oral health care of the college students investigated, 54.5 percent had ever visited a dental clinic over the last year, and 34.7 percent had their teeth scaled over the last year. Regarding self-awareness of current oral health state, 77 percent felt there s something wrong with their oral health. Concerning the correlation of their oral health behavior and knowledge to each selected variable, better internal and external locus of control led to better oral health promotion behaviors and better oral health knowledge. As to their self-perception of oral health and influential factors, better toothbrushing, better dietary habits and periodical oral examination, which belonged to oral health promotion behaviors, were followed by better oral health locus of control, and higher concern for oral health led to better oral health locus of control as well. Better toothbrushing, better dietary habits, periodical oral examination and better internal locus of control were concurrent with higher interest in oral health. Better external locus of control and stronger concern for oral health were accompanied by better oral health promotion behaviors.

Purpose: Interest in peptic ulcer in children has been relatively low because the disease is rarer in children than in adults and there were restrictions in the application of endoscopy to children, but the recent development of pediatric endoscopy is activating research on pediatric peptic ulcer. Thus, this study compared the $H.$ $pylori$ infection rate and clinical and endoscopic findings among pediatric patients diagnosed with peptic ulcer. Methods: We analyzed retrospectively 58 pediatric patients for whom whether to be infected with $H.$ $pylori$ was confirmed selected out of pediatric patients diagnosed with gastric ulcer or duodenal ulcer through upper gastrointestinal endoscopy at the Department of Pediatrics of Gachon University Gil Hospital during the period from January 2002 to December 2007. A case was considered $H.$ $pylori$ positive if $H.$ $pylori$ was detected in the Giemsa stain of tissue or the results of UBT (urea breath test) and CLO (rapid urease test) were both positive. Results: Of the pediatric patients, 37 were infected with $H.$ $pylori$ and 21 were not. The $H.$ $pylori$ infection rate increased with aging and the result was statistically significant ($p$<0.05). However, $H.$ $pylori$ infection was not in a statistically significant correlation with sex, chief complaint, and gastroduodenal ulcer ($p$>0.05). Conclusion: $H.$ $pylori$ infection increased with aging, but was not significantly correlated with gastroduodenal ulcer. Further research may need to examine prospectively the relation between $H.$ $pylori$ and gastroduodenal ulcer in the Incheon area.
