Auditory and language train for the hearing-impaired is an essential course improving conversational capability with non-deaf and accompanying the financial burden and the physical fatigue of parents or a teacher. To reduce these problems, web-based training contents have been developed. But these contents have been developed without consideration of individual difference such as various levels of residual hearing and the learning capability of hearing-impaired. Therefore, it is important that appropriate training progress for each hearing-impaired should be designed by evaluating and analyzing the personal status, residual hearing, learning capability and training achievement. This paper suggests auditory and language training service model for the hearing-impaired, which is planning and managing an auditory and learning training based on personal evaluation. In addition, this paper suggests a design method for a serious game content planing based on this service model.

의료기술 및 생활수준의 향상과 함께 우리나라의 평균수명은 꾸준하게 늘어 2026년에는 65세 이상 인구가 전체의 20% 넘을 것으로 예상되고 있다. 이러한 노인인구의 증가와 더불어 노인성 치매는 오늘날의 고령화 사회에서 높은 발병율(65세 이상 인구의 10%, 75세 이상 인구의 25%, 85세이상 인구의 50%에서 발생)을 보이고 있어 심각한 사회문제의 하나로 대두되고 있다. 또한 우리나라 치매노인의 증상은 가벼운 경우가 59.2%, 중등정도 27.2%, 아주 심한 경우가 13.6%이며 이중 치료를 통해 완치되는 경우는 겨우 14%에 불과하며 85% 이상이 치료불가능으로 보고되고 있다. 이와 같이 노인성 치매는 일단 발병하면 완전 치료가 거의 불가능할 뿐만 아니라 심하면 한가정의 파탄을 초래하기도 할만큼 치매간호에 소요되는 정신적, 육체적, 경제적 고통은 막대하다. 따라서 의 \ulcorner 약학계에서도 치매치료제에 대하여 다각도로 연구하고 있으나 지금까지 개발된 화학적 합성 의약품은 그 효능여부와 부작용 등의 논란이 크게 대두되고 있으며 또한 치매는 어떠한질 병보다 예방의 중요성이 인식되고 있는 만큼 이러한 부작용을 최소화 할 수 있는 예방 또는 개선차원의 식품소재개발이 중요하다고 하겠으며 이에 대한 연구자의 관심이 집중되고 있다. 본고에서는 현재 치매예방 및 치료제의 개발현황을 살펴보고 한약재를 이용한 치매예방 및 치료소재의 연구동향을 소개하고자 한다.

One of central issues in the Literature and Science discourses during the Victorian era is the relation of physiology to psychology. Many thinkers tackle the question of whether or not psychic phenomena can be reducible to their physiological bases. For instance, Victorian physiologist William Benjamin Carpenter claims that there should be a boundary between physiological and psychological qualities. Yet, his contemporary writer Grant Allen contends for the reduction of psychology into physiology. In the essay, I discuss Grant Allen's work Physiological Aesthetics (1877) so as to eventually problematize his physiological reductionism. I especially highlight the paradox of his physiological aesthetics. In order to clarify my argument, I introduce two concepts: evolutionary aesthetics and physiological reductionism. On the one hand, Allen argues for the development of aesthetic appreciation. The gradual evolution from gaudy to serene colors, for instance, reflects the fine differentiation of sensory organs. He believes that the existence of varied aesthetic pleasures corresponds to the evolution of sensory nerve structures. Nonetheless, Allen ironically gives more weight to the commonality of aesthetic experiences than to this teleological ordering of aesthetic experiences. He argues that there is no fundamental difference among humans in terms of their aesthetic assessments. Furthermore, there is even no essential distinction among plants, animals, and humans in light of their aesthetic appraisals, he states firmly. Although he asserts the gradual advance of aesthetic feelings caused by the intricacy of nervous systems, he simultaneously trivializes the evolution of aesthetic appraisal. In the essay, I highlight this paradox in Allen's physiological aesthetics. It should be underscored, lamentably enough, that Allen seeks biological purity by erasing fine lines among physiology, psychology, and sociality. He estranges aesthetic experiences from subjective variations and their socio-cultural contexts. He makes great efforts to eliminate individual differences and socio-cultural specificities in order to extremely biologize aesthetic experiences. Hence, Allen's physiological aesthetics is marked as the politics of physiological purification.

This study aims to identify the relations between self-reported symptoms of industrial workers work-related musculoskeletal disorders and psychosocial factors. The subjects of the study were 120 male workers who were using the rehabilitation center of K company and they were voluntarily interviewed with a use of organized questionnaire. Except the responses from eighteen subjects whose responses were insincere and who had disorders in musculoskeletal areas, the responses of 102 ones were decided for the final analysis. The results showed that there were significant differences in self-reported symptoms of work-related musculoskeletal disorders between the subjects according to smoking, physical burden and self-efficacy. To prevent and control work-related musculoskeletal disorders, multi-characteristic aspects of how the disorders appeared and psychological factors, in particular, self-efficacy, should be carefully considered. Then, as psychosocial factors affect musculoskeletal disorders, relations between the disorders and factors should be analysed through long-term follow-up studies, psychosocial factors should be actively intervened, and the effect should be evaluated.

Background : The aim of this study was to confirm the risk factors for low back pain and injury to improve the prevention and treatment of lower back pain. Materials and Methods : An epidemiologic study of low back pain and injury was performed with questionnaires distributed to 471 women working at Yeungnam university hospital. The differences in low back pain and injuries among various hospital departments were analyzed by a one-way analysis of variance (ANOVA), and the relevant factors included in the questionnaire were determined by a factor analysis. Results : The frequency of low back pain in women in the department of diet and in the maintenance department was higher than among the other departments. The frequency of low back pain was mainly related to the frequency of psychosomatic symptoms. In addition, the low back pain was partially related to the frequency of psychosomatic symptoms and partially related to the frequency of pushing during the workday. The degree of disability from low back pain was increased by lifting and hard physical work and was related to the frequency of psychosomatic symptoms and the degree of work dissatisfaction. The frequency of low back injury was increased by increased standing time during work and hard physical work. The frequency of low back injury was related to advancing age and in part to psychosomatic symptoms. Conclusion : Lower back pain and its associated complications are related to psychosomatic factors and type of work. Lower back injury is related to physiological factors such as age. For the prevention and treatment of lower back pain, a multidisciplinary approach is required.

This study was conducted to investigate the relationship between alcohol consumption, physical activity and breast cancer risk in Korean women. Newly histologically identified cases (N = 108) were selected at Hanyang and Soonchunhyang University Hospitals in Seoul, from January 1998 to August 1999. Hospital-based controls (n = 121) were the patients who visited at the same hospital in the department of plastic surgery, general surgery and opthalmology. Subjects were asked informations on demographic, reproductive, and history of breast feeding as well as physical activity, exercise habit, alcohol consumption by individual interview. Odds ratio (OR) and 95% Confidence Intervals (CI) were calculated by using unconditional logistic regression after adjusted for confounding factors. Among postmenopausal women, the risk of breast cancer increased with increasing alcohol drinking: relative risk for the highest group ( $\geq$ 150 g per week) compared with the lowest group (never drinking) was 2.05 (CI=1.74-3.79). Association of exercise and high physical activity for breast cancer appeared to be limited to women with high physical index among postmenopausal women. We observed decreasing risk of breast cancer with increasing physical activity index among postmenopausal women (OR=0.49,95% CI=0.56-0.92). Results of this study support a protective effects of physical activity during adulthood for breast cancer. (Korean J Nutrition 36(1): 40-48, 2003)

Acute or repeated physical exercise affects a large number of physiological parameters including hemodynamics, respiration, pH, temperature, gastrointestinal function and biotransformation, which determine the pharmacokinetics of drugs and chemicals. The rate and the amount of a chemical reaching the active site are altered by physical exercise, which results in significant changes in pharmacolosical/toxicological activity of the chemical. This aspect of physical exercise has vast implication in therapeutics and in safety evaluation, particularly for chemicals that have a low margin of safety. However there appears to be a wide inter- and intraindividual variation in the effects of physical exercise depend-ing on the duration, intensity and type of exercise, and also on the properties of each chemical. It is suggested that more studies need to be done to determine which factor(s) plays a major role in the disposition of chemicals in human/animals performing physical exercise. Certain chemicals induce severe toxicity due to metabolic conversion to reactive intermediate metabolites. it is suggested that repeated exercise may enhance the free radical scavenging system by increasing the activity of antioxidant enzymes. This area of research remain to be explored to elucidate the interaction of exercise and chemical on the antioxidant system.
