  • This study is about saliva from a GIGONG's point of view, it's importance, and it's funtion that recently medical world proved. And here is GIGONG training with saliva. The results were summarized as follows. 1. It is detected that saliva have function to prevent symptoms of senility and have effect of an $anti{\sim}cancer$ medically in recent years. So it is said that science proved narrowly that so called a predecessor speak of salive interms of high praise and they already experienced. 2. Similar substance to saliva exist in human body besides nature food, but human body have materials that deal with all situation to occur from every kind of environment and disease. And exactly saliva is an example of it. 3. We cannot turn back sweat, blood, tears and sperm again that is out of human body once, but we can swallow again only saliva. Therefore, we must experience training that swallow saliva to make us healthy by ourselves, and we don't have to commit a foolish act to cough up saliva at random that a predecessor speak of in terms of high praise, and to be second to JUNG(精). 4. Saliva is a kind of antibody or hormone, so I think that we need to make a study of using saliva with a GUIGONG that is an example of way to strengthen immunity of human body.

  • In this study, the influence of electromagnetic wave effected on human body of light sensing was classified. Subjects of the eye was stimulated by the rays of LED and the measured electrical signals(EEG, EOG and ERG) in human body were compared and analyzed in the case of exposed at electromagnetic wave or not. The result show that when the subjects were not exposed at electromagnetic wave, the ratio of a wave has a large percentage in the EEG signal and the ratio of $\beta$ wave has come to good.

  • For this purpose, the authors proposed and proved usefulness of the modified mean skin temperature which is integrated mean radiation temperature and the effect of floor contacted heat conduction. The mean radiation temperature is applied form factor between half cross-legged human body and surrounding wall of indoor. In addition the floor contacted heat conduction is applied heat transfer coefficient of half cross-legged human body. Eight Korean young men were targeted for the experiment. From the experiment the authors excerpted physiological reaction and psychological reaction in Ondol environment which is combined physiccal environmental factor of artificial climate chamber, air and floor temperature. As a result of the experiment it is confirmed that heat conduction has more impact than heat exchange from existing research for the heat exchange between half cross-legged human body and surrounding wall in Ondol thermal environment. Thereby, it is proved the effectiveness of the modified mean skin temperature which is added floor contacted temperature to the Ondol thermal environmental evaluation index.

  • The use of relaxing cosmetic products is more and more widespread on the self care market, since stress is considered as a major cause of discomfort in modem life. Cortisol, the stress hormone, helps the human body to regulate itself by acting on carbonhydrate, proteins and fat metabolisms. IgA are immune molecules involved in the stress response of the human body. The less the human body is stressed, the more the salivary IgA rate increases. Salivary cortisol and IgA have the advantage of being easily assessed with non invasive methods. Finally, conductance is the measurement of the modification in the electrical resistance of the skin. By this means, the measurement of the conductance enable the assessment of somebody's stress.(omitted)

  • 본 논문에서는 MICS(Medical Implant Communication Service, 402~405 MHz)와 ISM(The Industrial, Scientific and Medical, 2.40~2.485 GHz) 대역에서 동작하는 의료용 무선 중계 시스템을 위한 이중 대역 인체 부착형 안테나를 제안하고, 인체의 영향을 고려한 안테나 성능에 대한 분석을 하였다. 제안된 안테나는 ISM 대역에서 동작하는 윗면의 패치와 MICS 대역에서 동작하는 바닥면의 패치로 구성되어 있다. 안테나가 실제 인체에 착용되어 사용되는 상황을 고려하고, 인체가 안테나에 미치는 영향을 분석하기 위하여 모의 인체를 이용하여 시뮬레이션과 측정을 수행하였다. 제안된 안테나의 반사 손실은 MICS 대역과 ISM 대역에서의 요구 대역폭을 만족하였고, 측정된 최대 이득은 MICS 대역과 ISM 대역에서 각각 -12.47 dBi, 1.71 dBi이었다. 제안된 안테나의 방사 패턴은 MICS 대역에서 인체 내부 지향성, ISM 대역에서 인체 외부 지향성을 가지며, 반사 손실 특성은 인체의 영향에 매우 둔감하므로 의료용 무선 중계 시스템용 인체 부착형 안테나로 활용되기에 적절할 것으로 사료된다.

  • During running, the human body experiences repeated impact force between the foot and the ground. The impact force is highly associated with injury of the lower extremity, comfort and running performance. Therefore, shoemakers have developed shoes with various midsole properties to prevent the injury of lower extremity, improve the comfort and enhance the running performance. The purpose of this study is to investigate influence of midsole hardness on shock absorption along the human body during running. Thirty two expert runners consented to participate in the study and ran at a constant speed with three different pairs of shoes with soft, medium and hard midsole respectively. Using accelerometers we measured the shock absorption from shoe heel to cervical vertebral column. In conclusion, at the shoe heel, shock was the greatest with the hard midsole. However because most shock was absorbed between shoe heel and the knee, notable influence of midsole was not detected upper knee. At shoe heel, regardless of midsole hardness, the shock of younger female was the greatest. The authors expect to apply this result for providing a guideline for utilizing proper midsole hardness for manufacturing age and gender-specific shoe.

  • The purpose of this study is to clarify the floor temperature on the human body and to estimate thermal comfort zone in a heated room. In order to evaluate the effects of floor heating, a series of experiments were carried out using Korean subjects. The following experiments were conducted: 1) to obtain the effective radiation area and configuration factors of the person in the sitting posture on a floor to get the mean radiant temperature, 2) to measure contacted area of the person to the floor to calculate conduction heat rate, 3) to measure convective heat transfer coefficient of the body and 4) to know the thermal comfort zone of indoor environment heated by ON-DOL. Subjects were exposed to the following conditions: combinations of air temperature $20^{\circ}C$, $22.5^{\circ}C$, $25^{\circ}C$, and floor temperature $20^{\circ}C$, $22.5^{\circ}C$, $25^{\circ}C$, $27.5^{\circ}C$, $30^{\circ}C$, $32.5^{\circ}C$, $35^{\circ}C$, $37.5^{\circ}C$, $40^{\circ}C$ under still air and 50% relative humidity in the controllable artificial climate chamber. To evaluate the effect of heat conduction between the body and a floor modified mean skin temperature was defined. Weighting coefficient to calculate mean skin temperature were modified with the contacted area. The experiments revealed a positive correlation between the modified operative temperature and the modified mean skin temperature. The modified mean skin temperature can indicate the effect of heat conduction between body and a floor surface.

  • 최근 몇 년간 전자파 관련 장비 사용이 증가함에 따라 전자파의 인체 영향 또한 관심이 증가하고 있으며, 또한 이러한 영향을 구체적으로 파악하기 위한 연구가 진행 중이다. 이에 대한 일환으로 이동 통신 단말기에 의한 전자파 인체 흡수율(SAR)에 의한 국내외 표준 제정에 관한 연구가 활발히 진행되었다. 그러나 인체에 대한 침투력이 상대적으로 큰 단파 대역(HF: High Frequency)에 의한 인체 유도 전류에 대한 표준은 연구가 미흡한 편이다. 특히 교통 카드와 도서관 등에서 사용되는 RFID 장비의 활발한 도입으로 RFID 장비의 방출 전자파에 의한 인체 영향 연구가 절실하다. 본 논문은 단파 대역인 13.56 MHz에서 동작하는 RFID 장비에 의하여 인체에 유도되는 전류와 유사한 유도 전류값을 갖는 실린더형 인체 등가 안테나 모형을 설계 및 제작함으로써 RFID 장비의 방출 전자파에 의한 인체의 영향을 양적으로 파악하고, 인체와 인체 등가 모형에 유기되는 유도 전류의 유사성을 확인하였다.

  • 신체화의 개념과 기전에 관해, 정신분석 이론을 비롯한 많은 이론들이 제시되어 왔다. 저자는 인간의 본질(존재의미의 이해)에 대한 통찰력에서 출발하고 있는 현존재분석의 관점에서 신체화의 개념을 제시하려는 것이다. 현존재분석에서 보는 신체화 현상은 인간의 세계관계의 직접적 표현이다. 현존재분석에서는 신체라는 말 대신에, 의미를 드러내는 '신체성'을 말하고 있기 때문에, 신체화 현상의 이해란 그 현상이 드러내는 의미를 보는 것이다. 그리고 신체화 현상은 세계관계의 직접적 표현이기 때문에 그 현상이 드러내는 의미는 그 인간의 세계관계에 의해 결정된다. 그 현상의 의미를 이해하는 방법은 현상학적 방법이다.

  • This study attempted to make a comparative analysis of dress and architecture to investigate the spatial effect of transparency expressed in fashion. As a result, the following findings were obtained: First, the openness of the space. It means that the human body or the dress inside it can be seen through or the inside space is opened. The volume, form and color of the undergarment seen through this transparent outer garment brings about any change to design. Also, it can be found that the role of the space is further extended as the inside space is seen through outwardly due to the outer garment. Second, interpenetration of the internal and external space. That the human body and the undergarment are seen through due to transparent dress brings about the linkage between spaces and opens the inside outwardly. Third, the briskness of the space. The trait of transparency that exposes the object behind outwardly as it is causes its form and space to be activated and conveys its spatial briskness.
