The concept of universal design has recently emerged as an important aspect of product design. Universal design is considerably analogous to ergonomic design in a way that it takes the capabilities and limitations of users into consideration during the product development process. However, relatively few studies have been devoted to reflect the practical use of ergonomic principles on universal design. This research attempts to develop a universal design index for mobile phone design to quantify how well a product complies with principles of universal design. The research also emphasizes on ergonomic principles as a basis of evaluation. A generation of the evaluation items was done by cross-checking among the personal, activity and product components. Personal components consist of human characteristics including age, physique, perceptual capacity, life-style, etc. Activity components were derived from those scenarios of mobile phone use while product components were composed of the parts to which a user interacts. Further analysis systematically generated a universal index from relationship matrices among the three components. The index was then used to test its suitability by applying to the evaluation of mobile phones currently on the market. This study demonstrates a development process through which evaluations can be made possible for universal design. The research suggests an improved approach to the appraisal of how well mobile phones are universally designed based on ergonomic principles.

This study was conducted to observe the isokinetic strength (IS) of the hip, ankle, and knee joints in young age groups. Thirty eight men and thirty one women with mean age of $30.4{\pm}3.5$ and $32.8{\pm}4.4years$, respectively, were enrolled in this study. Measurements of hip flexion, extension, abduction, and adduction at $30^{\circ}/sec$, Knee flexion and extension at $60^{\circ}/sec$, ankle inversion, eversion, plantarflexion, and dorsiflexion $30^{\circ}/sec$ were conducted. Absolute IS (Nm), relative IS (Nm/kg), strength ratios, correlations between movements were observed. Significant differences in absolute and relative strength were observed between groups in all movement except in the relative ankle strength. Relative isokinetic strength ratios of hip flexion/extension were .45 and .55, knee flexion/extension were .84 and .89, ankle dorsi/plantarflexion were .30 and .29, and ankle eversion/inversion were .86 and .84 for men and women, respectively. In the hip extension, men had about three times the body weight, and women had about 2.5 times the strength. The abduction muscle had about 1.5 times the body weight of both men and women. Height and body weight showed the significantly strong correlating relationship with hip (r, .76-.86) and knee (r, .67-.84) strength. However, ankle strength showed the comparatively correlating relationship, especially in women (r, .03 - .36). Similar age and physique characteristics of female and male groups could provide useful isokinetic strength reference values for developing the exercise program for healthy and rehabilitation groups.

울산광역시 매곡동 일대에서 새롭게 발견된 단층대의 기하학적, 운동학적 특성 및 제4기 단층운동에 대해 알아보고자 야외조사를 통한 지질구조분석을 실시하였다. 그 결과, 퇴적암이 분포하는 첫 번째 조사지점에서는 100 m 내외의 절취사면을 따라 반복층서, 소규모 단층, 단열대, 변형띠대 등이 연속적으로 관찰되고 있어, 이 지점은 대규모 단층의 손상대에 속하는 것으로 해석된다. 한편 주로 화강암 암편으로 구성된 쇄설성 퇴적층이 분포하는 두 번째 조사지점에서는 저각의 경사를 보이는 여러 조의 단층이 서로 분지 또는 결합하는 형태로 발달하고 있어 대규모 역단층이 발달하는 것으로 판단된다. 이 단층의 단층비지 내에 포함된 유기물의 방사성탄소연대에 기초해 추론된 단층의 최후기 운동시기는 33,275 ± 355년 전 이후로 제한된다. 이번 조사에서 확인된 단층대의 손상대 규모, 운동감각, 운동시기 등은 이 단층대가 연구지역 인근의 대규모 신기단층으로 알려진 울산단층 또는 연일구조선과 밀접한 관련이 있음을 시사한다. 따라서 연구지역 일대에 조성 중인 산업단지와 아파트를 비롯한 여러 시설물에 대한 지진 및 지질학적 안정성을 확보하고 이 지역에서의 지질재해에 대비하기 위해서는 보다 정밀한 구조지질학 및 고지진학 관점에서 이 단층에 대한 연구가 필요할 것으로 판단된다.

The purpose of study to phenomenological examine and the mechanism regarding the gene(DNA, RNA, Protein) and sports to studied, analyzed. and evaluated. This review considers the evidence for genetic effects in several determinants of endurance performance and resistance performance, namely: body measurements and physique, body fat pulmonary functions, cardiac and circulatory functions, muscle characteristics. substrate utilization, maximal aerobic power and other. Moreover, the response to aerobic training of indicators aerobic work metabolism and endurance performance is reviewed, with emphasis on the specificity of the response and the individual differences observed in training ability. This study indicate that improvement of 'Enhancer Action' in RNA genes changed by exercise or sports. Moreover exercise was effect on Central Dogma with DNA makes RNA makes Protein. and think that occurred with exercise influence on skeletal muscle into cell have to Myosin Heavy Chain (MHC) changed was after exercise performance, which accompanied into skeletal muscle that were exercise-induces gene-modulation that is, take gene mutations. This study known that existed hormone(epinephrine)-immune system with interaction. Exercise were altered insulin binding and MAP Kinase signaling increased into immune cells. This review suggested that the high rate of glutamine utilization by cells of the immune system serves to maintain a high intra cellular concentration of the intermediates of biosynthetic pathways such that optimal rates of DNA, RNA and protein synthesis can be maintained. In the absence of glutamine, lymphocytes do not proliferate in vitro: proliferation increase greatly as the glutamine concentration increase. Glutamine is synthesized in skeletal muscle. Skeletal muscle and plasma glutamine levels are lowered by sepsis, injury, bums, surgery and endurance exercise and in the overtrained athlete. The study of result show that production of ET-1 is markedly increased tissue specifically in the heart by exercise without appreciable changes in endothelin-converting enzyme and endothelial receptor expressions, suggest that myocardial ET-1 may participate in modulation of cardiac function during exercise. Conclusionally, this study indicate that improvement of 'Enhancer Action' in RNA genes changed by exercise or sports. Moreover exercise was effect on Central Dogma with DNA makes RNA makes Protein. This study is expected to contribute the area of sports science, medicine, hereafter more effort is required to establish the relation between gene alters and exercise amount.

The purpose of this study was to analyze the effects after having the obesity education with obese elementary school children. The subjects were made up of 31 obese children out of U elementary school in B town as experimental group, and also were selected 34 children out of S elementary school under the same circumstance as control group. They ranged from the third to sixth grades with over 30% body fat ratio. The proceeding of obesity education consisted of three stage; stage for preparation, stage for practice, and stage for finish. The stages mentioned above were put into practice in turn for eleven weeks beginning on Oct. 8, 2001 through Dec. 22, 2001, while two stages only, stage for preparation and finish, were put into practice on the control group. The contents of the education for eleven weeks obesity regulation contained counseling and taking regular exercises once a week by professional gym teacher. In order to evaluate the effects of the education, physical characteristics, body composition, physical fitness, knowledge of obesity, dietry habit and attitude were measured. The obtained data were analyzed using SPSS program, the effects of pre and post obesity education in experimintal group were measured by paired-t test. The conclusions of this study were as follows : 1. Body fat ratio was significantly reduced after obesity education in experimintal group(p=.003). 2. The height with experimental group got taller remarkably(p=.000), but weight showed no signeficance after obesity education(p=.258). 3. Triceps and subscapular skinfold thickness showed remarkable decrese after obesity education(p=.000), percentage body fat and body fat amount got down remarkably after obesity education(p=.000). Percentage lean body mass and lean body mass amount got down remarkably after obesity education(p=.000). 4. Body flexibility, agility and muscle endurance graded up remarkably after obesity education(p=.009, p=.000, p=.000). 5. The grade in obesity knowledge got up remarkably after obesity education(p.000), but dietry habits and its life showed no significance in figures after obesity education(p=.335, p=.112). Through the results shown above, the obesity education caused body fat ratio, physique, body composition to grade up and physical fitness elevated, while dietry habits and its life showed no significance.
