  • This paper presents a new formulation for transient simulations of microwave propagation in heterogeneous unbounded domains. In particular, perfectly-matched-layers(PMLs) are introduced to allow for wave absorption at artificial boundaries used to truncate the infinite extent of the physical domains. The development of the electromagnetic PML targets the application to engineering mechanics problems such as structural health monitoring and inverse medium problems. To formulate the PML for plane electromagnetic waves, a complex coordinate transformation is introduced to Maxwell's equations in the frequency-domain. Then the PML-endowed partial differential equations(PDEs) for transient electromagnetic waves are recovered by the application of the inverse Fourier transform to the frequency-domain equations. A mixed finite element method is employed to solve the time-domain PDEs for electric and magnetic fields in the PML-truncated domain. Numerical results are presented for plane microwaves propagating through concrete structures, and the accuracy of solutions is investigated by a series of error analyses.

  • In many countries the demographics clearly informs us that an aging population represent a serious problem. To this extent senior citizens welfare does matter it has developed into a public debate and genuine concern. it seems that the social issues are focused on how the socity views the social welfare policies. In a modern welfare state where the emphasis lies in pursing a high standard of living and thereby high quality of life. This does not cover the very well the old people in society, but the government clearly carries an obligation to look after and care for the retired & old people in the society. This obligation the social and economic impact that an old person faces as he/she grows old. it is important ensure that their lives carries a meaning and that they as a group will not be estranged from the mainstream of society just because they are considered to be part of the aging population. The key issues that must be addressed are 1) The impact of reduced spending power from less income. a lower income stream; 2) increasing health problems and costs; 3) the natural degradation of ones physical & mental powers; 4) and thereby an isolation from the public in general. So clearly the social policy related to the old people in society should be developed with the consent of what they believe is important to them. To ensure their minimum income level that a beneficiary of an old person's pension will receive, the monthly pension should be reflected by the official price index and be adjusted accordingly. by making the job market open for the senior citizens, expending the mandatory retirement age, give companiesincentives to hire senior citizens, there maybe an opportunity to extend to the aging population the possibility to continue to participate in the society at large.

  • The purpose of this study was to provide basic data for the development of medicinal herbs, which are useful for the treatment of chronic diseases and physical characteristics of the elderly. A total of 151 adult women aged 65 years or older currently living in Daejeon were enrolled. The contents of this study were parents' health status, recognition of the necessity for a dietary therapy, awareness of medicinal herbs, requirements for medicinal herbs, physician of medicinal herbs and obstacles to medicinal herbs. Based on these results, the differences in the perception of medicinal herbs according to the dietary needs group as well as differences in the perception of medicinal herbs according to medicinal herbicidal groups were analyzed. Of the 151 subjects, 90.7% were married, and 44.4% of them were aged between 40 and 49. Most of the patients were aged in their 70s (68.9%), and 79.5% of had chronic illnesses such as high blood pressure, hyperlipidemia, arteriosclerosis, and heart disease. It is recognized that dietary therapy is necessary for the treatment of diseases, and awareness of medicinal herbs is low but necessary. As for the requirements for medicinal herbs, the most favored was 'porridge for the prevention and treatment of diseases', and 72.2% of medicinal herbs were physicians. However, problems cited were availabitity of ingredients, cooking technique, price of ingredients, and others. In addition, both groups requiring dietary therapy and having high awareness of medicinal herbs felt that medicinal herbs would be helpful in treating diseases. Therefore, it is necessary to provide a simple medicinal herb recipe for each disease and to develop anti cooked medicinal herbs.

  • Objectives : The aim of this experiment is to find out relationship between the effect of cosmetics and 4 types of pattern identification about fluid-humor, which are based on the general idea of traditional oriental medicine, Qi-Blood and deficiency-excess. Methods : Korean female volunteers in good health (n=25, $23.12{\pm}2.83$) participated in this experiment. Three Korean medical doctors classified them into 4 groups: Blood-deficiency: group A; Blood-excess: group B; Qi-deficiency:group C; Qi-excess:group D). Cosmetics that contains herb extract for Blood deficiency were given to all volunteers and they used the cosmetics for 4 weeks. Volunteers were assessed non-invasively with the skin measuring devices before and after using cosmetics. And we analyzed the correlation of skin physiological parameters with 4 groups. Results : Three doctors diagnosed participants and classified them into 4 groups ; group A(n=8),group B(n=7), group C(n=3), group D(n=5) as highest score. After 4 weeks, facial skin moisture showed no significant difference in comparison between 4 groups. Sebum showed significant increase in Group A and significantly decreased Group B. Measurement of facial skin elasticity tended to increase in Group A, C, D but skin elasticity was decreased significantly in Group B. Conclusions : In case of a group that pattern identification about fluid-humor corresponds to herb extract in cosmetic, skin improving effect was better than the other group that pattern identification oppose to properties of herb in cosmetic. Therefore, from the view of traditional oriental medicine, it is very important to understand user's pattern of identification or physical conditions and properties of herbs in cosmetics on the matter of safety and efficacy.

  • This study was performed to investigate dietary habits, and to evaluate the relationship between nutritional status and certain blood parameters in premenopausal and postmenopausal women living in Daejeon. Adult Korean females(n=110) that had visited the Health Promotion Center of Eulji University Hospital were analyzed. We examined blood parameters, body composition, and life style factors such as food habits and physical activity in pre- and post-menopausal women. The collected data were then analyzed to evaluate the various items. Overall, there were no differences between the pre- and post-menopausal women for food habit score, or for intakes of energy, protein, Int, iron, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, vitamin C, and calcium. However, carbohydrate intake was significantly higher in the postmenopausal women than in the premenopausal women. The Dietary Reference Intakes for Koreans(KDRIs), in terms of energy, fat, calcium, vitamin A and vitamin $B_1$, were less than 100% in both the premenopausal women and postmenopausal women. All intakes of protein, iron, vitamin $B_2$, niacin, and vitamin C satisfied the KDRIs in both groups. Finally, the postmenopausal women had higher serum fasting blood glucose, total cholesterol, LDL-cholesterol and alkaline phosphatase levels than the premenopausal women.

  • In this paper, we have developed a tongue diagnosis system using fuzzy rules. A healthy person's tongue is red in color and has less tongue coating. However, when a person suffers from a disease, the color of their tongue changes from red to white, blue, or black. Therefore, it can analyze patient's health if analyze color and coated tongue of tongue. Medical diagnosis system can automatically determines the symptoms of the disease of a patient and their and calculate the optimal acupuncture time on the basis of the patient's physical conditions, illness conditions, and age from any place and at any time. The computer simulation results have shown that electro-acupuncture administered by using the medical diagnosis system developed in this study is more effective than the conventional method.

  • These days, IoT attached diaper are available in markets. It measures child's temperature, oxygen rate, or even humidity of diaper and send the result directly to parent's smartphone. This research emphasize the followings, due to the fact that use of IoT in context of infant care should ultimately be leaded to infant's wellbeing and healthy development. First, there can be many problems when you only focus on usability without careful consideration of the accuracy of the infant's health information produced by the IoT. Second, infant's needs and nature of child should be reflected when developing IoT which supports infant care. The use of the IoT should not take away the chance of physical contact such as eye-contact or patting and hugging between the caregiver and baby. IoT is very important, however in terms of infant development, connect with IoT cannot antecede contact with child.
