  • The desirable method to diagnose abnormal blood pressure is to measure and manage blood pressure continuously and regularly. However, the sphygmomanometers that are based on a cuff have faults in that they can not measure the blood pressure continuously and they cause an unpleasant feeling. Therefore, it is essential to develop a new measuring method that causes no pain and that can obtain blood pressure continuously without any unpleasant feeling. Thus, we propose here a regression method to estimate the systolic blood pressure by using the PTTL(pulse transit time on leg) with some body parameters which are chosen from the relational analysis with systolic blood pressure. The data we use to make the regression model were obtained in triplicate from each of 50 males who were from 18 to 35 years. And we made estimation experiments of blood pressure on 10 males who did not take part in the making the regression model. According to the results, the proposed method showed a mean error of 4.00 mmHg and the standard variance was 2.45 mmHg. When we comparing the results of the proposed method with the rule of American National Standards Institute of the Association of the Advancement of Medical Instruments(ANSI/AAMI), the results satisfied the rule of a mean error less than 5 mmHg and a standard variance less than 8 mmHg. Therefore we were able to validate the usefulness of the proposed method.

  • Aversion to wind is a feeling of cold when exposed to wind; aversion to cold is a feeling of cold. The distinction between aversion to wind and aversion to cold is ambiguous because in greater yang disease the two terms seem to be used indiscriminately. It is, however, worth noting that "aversion to wind" does not occur in the lines presenting disease of the three yin. In this text, we render as "heat effusion" rather than "fever," since the Chinese term is somewhat wider in meaning than familiar English term, Heat effusion is associated with many conditions and occurs both in externally contracted disease and miscellaneous disease (雜病), disease due to causes other than external evils). In externally contracted disease of the three yang channels, heat effusion is a manifestation of the struggle between right qi and evil qi; it does not necessarily indicate the presence of evil heat. In diseases of the three yin, right qi is not strong enough to counter evil qi; hence heat effusion is absent, and instead only aversion to cold is present. Sweating occurs in a variety of patterns. A distinction is made between spontaneous and night sweating(自汗). Spontaneous sweating is so called because it occurs spontaneously without exertion. it has numerous causes. Night sweating(盜汗) is sweating during sleep that ceases on awakening.

  • Purpose: The purpose of this study was to identify the factors that influence depression, suicidal thought, and life satisfaction of Korean elders. Method: The subjects for this study were 219 Korean elders living in three different provinces. The data was collected using structured questionnaires from October through December, 2007. Result: There were statistically significant differences in the levels of depression, suicidal thought, and life satisfaction according to age, health state, sleep state, economic state, feeling of loneliness, feeling of abuse, and having friends or neighbors. Suicidal thoughts correlated less with the above factors than depression did. Depression significantly correlated with age, life satisfaction, loneliness and suicidal thought. Suicidal thought was influenced significantly by depression. Life satisfaction was influenced significantly by depression, health state, and economic state. Conclusion: It could be concluded that nursing interventions for reducing depression and suicidal thought should be developed to improve life satisfaction and the health state of Korean elders as well as to relieve their feelings of loneliness.

  • Objectives : Seborrheic dermatitis is an inflammatory skin disorder affecting the scalp, face, and torso. Typically, it presents with scaly, flaky, itchy, and red skin. It may be aggravated by illness, psychological stress, fatigue, sleep deprivation, change of season. The purpose of this study was to report the clinical effects of herbal medicine on Seborrheic dermatitisMethods : We employed oriental medical treatments; herbal-medication (Bangpungtongsungsangamibang), acupuncture, moxibustion and cupping therapy. At the same time, the patient sweated out the skin poison. We treated him two times a week with oriental therapy method. He took medicine three times a day after a meal. During taking medicine, we let him avoid fatty food, flour based food, and alcohol. We took a picture the patient's body parts and compared the symptom with previous symptom. With the picture, we evaluated the patient's condition.Results : After taking treatment - 77 times' acupuncture, moxibustion and cupping therapy during 9 months and taking herbal-medicine, the skin condition of the patient was much improved. At first, he was troubled with itching and hot feeling at reddish area, time after time the itching and hot feeling was weakened. The reddish area was changed to scaly and flaky skin and changed to normal state.Conclusions : Herbal medicine (Bangpungtongsungsangamibang) with oriental medical treatments was an effective in the treatment of Seborrheic Dermatitis and it helped to improve regenerating the skin in the body.

  • Conventional brake system was used for passenger cars and SUV for a long time. However, the high performance brake system has strongly required because of increase of engine power and customer's favorites etc. In this paper, a new high performance brake system for Europe was proposed. For this system, the high performance caliper and disc were newly developed. The superiorities of the developed high performance brake system were verified via heat capacity, hydraulic stiffness, corrosion and harsh braking mode test. Also, the high performance caliper and disc for the light-weight were applied to AL-Alloy and can obtain the weight reduction effect of 2.9 kg per vehicle. Finally, a developed high performance brake system is expected to be used for realization of the high performance at the same platforms.
