윤형식,황성호,이현륭,김수호,박연석,권낙현,정호진,김동훈,노현주,홍성호,박병찬,이관,정해관 東國大學校醫學硏究所 2002 東國醫學 Vol.9 No.1

일상생활에서 모발염색은 흔히 접할 수 있는 미용의 한 종류로 특히 젊은층을 중심으로 폭발적으로 유행하고 있다. 염색을 위항 사용하는 약제는 표백제와 발색제 등 각종 화학약품이 사용되고 있으나 이로 인한 건강장해에 대한 연구는 그리 많지 않다. 저자들은 염색이 인체의 모발건강에 미치는 영향을 파악하기 위하여 염색과 관련된 주관적 증상과 모발의 변화에 대한 실험적 연구를 시행하였다. 동국대학교 경주 캠퍼스 재학생 80명을 대상으로 설문조사를 시행하여 염색 유 ·무 및 염색 후에 경험한 증상에 대해 설문 조사하였고, 의과대학 재학생 46명을 대상으로 피부 반응 테스트를 실시하였다. 또한 염색 전후의 모발 탄성도를 측정하였고 모발의 상태를 파악하기 위해 전자 현미경검사를 실시하였다. 설문조사 결과 염색 전에 비하여 염색 후 안구혼탁, 안구건조, 시력저하, 발진 및 접촉성 피부염, 모발손상, 모근손상 등의 증상을 더 많이 경험한다고 호소하였다(p<0.05). 모발손상과 모근손상은 헤어드라이어 사용 빈도에 따라 증가하는 것으로 조사되었다(p<0.05). 피부반응검사에서 가려움증이 가장 많은 증상이었으며 이는 여성보다는 남성에서 높은 것으로 조사되었다. 염색 전후의 모발장력은 염색 전 134.5±10.37g, 염색 128.0±30.69g, 염색 이틀 후 112.5±19.69g으로 나타났다. 염색 전후의 모발의 전자현미경 케라틴 층이 현저히 감소하고 모발이 가늘어지는 차이를 보였다. 염색은 모발손상, 모발 케라틴 손상 및 모근 손상, 발진 및 접촉성 피부반응, 안구혼탁, 안구건조, 시력 저하를 유발한다. 따라서 염색약으로 인한 손상에 대한 주의와 예방이 필요하다고 생각한다. 예방대책으로 염색 전 피부테스트를 통한 적합성 여부를 판단하는 것이 필요하며 가급적 염색을 피하는 것이 좋을 것이다. 염색약에 발암물질이 포함되어있다는 보고도 있어 염색 제조사의 철저한 실험과 염색 물질의 선별이 염색으로 인한 부작용을 최소화하는데 중요한 역할을 할 것이다. Hair coloring has became one of the most popular cosmetic activities to younger generations during last decade. However, there are few studies on the health effect of widespread use of chemical dyes. This study was conducted to study the effects of hair coloring dye on hair and other systems. We conducted a questionnaire survey of 80 persons in Kyongju campus, Dongguk University. We have done open patch skin test on 46 medical students. We also conducted scanning electron microscopy to examine the hair strength and structure before and after hair coloring process. Injury of hair and hair bulb, contact dermatitis, turbid eyes, xerophthalmia, and poor visual acuity were the main symptoms complained after hair coloring (p<0.05). Injury of hair and hair bulb were increased by frequency of hair-dryer use(p<0.05). In open patch test, pruritus was complanined by more than half of the subjects. Mean strength of hairs before and after hair coloring was as follows; 134.5 (SD 10.37)g before hair coloring, 128.0 (SD 30.69)g immediately after hair coloring, and 112.5 (SD 19.69)g after two days. The scanning electron microscopic findings of hair surface before and after hair coloring showed decreased keratin layer and thinning of the hair. Hair coloring induces injury to hair, its keratin layer, and hair bulb as well as contact dermatitis, turbid eyes, xerophthalmia, and poor visual acuity. Therefore, we think that precaution is needed in use of hair coloring dye. To prevent complications induced by hair coloring dye, it is necessary, especially to those with allergy or skin disorders, to perform skin test before action and avoid hair coloring whenever possible. Longterm health effects of hairdye should be studied and manufacturing companies should try to minimize complications induced by hair coloring dye.

Hardy시의 음악성 시비

유관현 서울産業大學校 1997 논문집 Vol.46 No.1

Since the first appearance of Hardy's Wessex Poems (1898) it has become a common option among his readers and critics that his poetry lacks music: his style is rugged and his diction eccentric. Samuel Hynes defends Hardy's poetry against this critical opinion and suggests that his harsh style is a metaphor for belief. These two opinion, however, are same in that they think Hardy's poetry lacks music in the sense of mellifluousness. P. E. Mitchell, again, refutes this critical view by reference to the tradition of English folk songs and ballads. This article, drawing on Mitchell, concentrates on the common qualities in the folk songs and Hardy's poems and on the significance of Hardy as a poet in the face of the industrial modern urban life.

This paper discusses an EMG based control method of a virtual robot arm as an adaptive human supporting system or remote control system, which consists of an shoulder control part, elbow control part, and wrist control part. The system uses three surface electrodes to acquire the electromyography(EMG) signal from operator. It is shown from the experiments that the EMG patterns during arm motions can be classified sufficiently by using SOFM(self-organizing feature map). The interface system based on PC environment is constructed to 3-D graphic user interface(GUI) program.

The purpose of this study was to verify what major muscles are during Taekwondo dolyechagi, and analyze major muscle fatigue and type on recruitment. 14 university students(male) were participated in the exercise test. The subject were divided into two groups; expert (N=7) and non-expert(N=7). Electromyogram test was analyzed muscle fatigue and type on recruitment during repeated dolyechagi by surface electrode. Major muscle was measured by Integrated EMG in main-test while dolyechagi 3 times. There were analyzed by Integrated EMG on Major muscle when lst, 2nd, and 3rd time of 100. Muscle fatigue was analyzed by MPF(mean power frequency) on Major muscle when dolyechagi lst, 20th, 40th, 60th, 80th, 90th and 100th time of 100. The results of this study as follows: 1. When Taekwondo dolyechagi, this study showed that major muscle of left foot was measured Left Tibialis anterior, Left Rectusfemoris, Left biceps femoris, Left gastrocnemius and major muscle of Right foot was Right Tibialis anterior, Right Rectusfemoris, Right gastrocnemius and Right biceps femoris. 2. When Taekwondo dolyechagi, this study showed that major muscle of left foot and Right foot was measured Tibialis anterior, Rectusfemoris. 3. non-expert group in dolyechagi significantly reunited more major muscles of Right foot than in expert group. However, expert group in dolyechagi significantly recruited more Left Tibialis anterior, Left Rectusfemoris than in non-expert group. 4. The change of the MPF in major muscles of LeftㆍRight Tibialis anterior, Leftㆍ Right Rectusfemoris were more statistically significant in dolyechagi than kuzu shi. This results suggested that muscle fatigue occured more in kake. The difference of MPF between non-expert group and expert group was resulted from high resistant capacity in expert group.

Universities play a part in growing men necessary in the society, instructing such humane education as liberty, equality and respecting human and producing leaders of ablility. Also, they contribute to the public benefit and the pursuit of happy life. So this society depends on universities, in turn, and universities always keep a variety of attempts in mind. Here are a few suggestions about service for society by universities based on the above. First, to make it more effective, as a prerequisite the matter of why-to-do-it must be comprehended, and a lot of service programs to respond the volunteers' expectancies and demands must be developed and cared for. Second, service for society has to include open-minded and pragmatism-centered universities' spirit. In terms of coexistence of universities and local societies, universities must have consistent connected activities from primary, middle to high schools with themselves in near future. Third, different programs are needed to satisfy students' demands and expectancies; in for whom, children, the elder and the disabled, in where, public places, organizations of consumer, environmental organizations, and social welfare facilities. Last, the sufficient resources provided by universities can result in the desirable activation of service for society. Therefore, educational and professional service for society according to the special characteristics of universities has to be developed.
