  • 간의 약물대사는 흡수된 외인성물질의 배설을 위한 중추적인 역할을 수행하면 이 반응은 일상대사와 이상대사효소로 구성된 약물대사효소계에 의해 매개된다. 약물대사효소의 발현과 활성은 외인성물질의 노출에 의해 유도되거나 억제되며 이 결과는 약물상호작용을 발생시키는 주요한 원인이다. 또한 당뇨, 비만, 영양실조, 음주, 염증반응 등의 병적인 생리상태는 간에서 약물대사효소의 발현과 활성을 조절하는 것으로 보고되고 있다. 이러한 변동은 치료약물 또는 환경오염물질에 대한 인체의 반응성에 영향을 미치며 결과적으로 예측하지 못한 부작용이나 독성을 발생시킬 수 있다. 본 논문에서는 당뇨병에서 약물대사효소의 발현변화를 정리하였다.

  • 전기는 오늘날 문명사회의 기초에너지로서 여러방면에서 이용되고 있으며 전기의 이용없이는 우리들의 문화생활과 산업활동은 있을 수 없다. 이와같이 없어서는 안될 전기도 한편으로는 매우 큰 위험성을 내포하고 있다. 그것은 전기가 인체에 흐름에 따라 발생하는 감전이라는 현상이며, 이러한 경우 어떤 때에는 중대한 감전재해가 발생하기도 한다. 감전재해는 전기가 갖는 위험성을 모른다거나, 혹은 위험성에 대한 인식이 부족함으로 일어나는 경우가 대부분이다. 그러므로, 전기가 갖는 위험성을 정확히 인식하고, 감전재해를 일으키지 않으며 전기를 이용하기 위해서 안전수칙, 접지공사등 여러가지의 대처방안을 이룩하여 안전을 도모하여야 한다. 본고에서는, 먼저 감전에 대한 인체의 생리학적 반응을 기술한 후 전기설비주위에서 발생하기 쉬운 감전사고를 방지하기 위한 대처방안으로서 지락보호에 대해 해설하고자 한다. 지락보호에는 그 계통의 접지방식에 따라 보호접지방식, 과전류차단방식, 누전경보방식, 절연변압기방식, 누전차단방식등이 있으며, 이들은 각각 나름대로의특징이 있으나 주로 누전차단 방식이 다른 것에 비해 적절하며, 세계적으로도 지락보호대책으로 보안효과를 높일 수 있는 누전차단기를 채용하고 있는 실정에 있다.

  • The following are the results from the infrared body temperature image test to verify the changes in facial temperature according to call duration with a cellular phone. As for the body temperatures, it appears to be the mean value at the upper central point of phone's battery among 7 different points that are measured, and to be the highest at srernocleido-mastoid and scapular trapezius muscle triangle zone$(34.25^{\circ}C\; and\;34.05^{\circ}C\;each)$. The changes of body temperature according to the time duration shows that the body temperature rises according to the length of phone use because of the heat emitted from the battery. As for the temperature changes according to blocking materials, the one without processing appears to be higher in the mean temperature compared to the others that are processed, NSS(Nano Silver Silk) and NSG(Nano Silver Silk Gold) appear to be the lowest in the temperature to show the best blocking property. As for the temperature changes according to measuring points, it appears to be the highest at P4, P5 with all materials, and one with NSG to be the lowest at Pl, P2, P3, and one with NSS to be the lowest at P3, P4, P5, P6, which is due to the thermal conduction of Au and Ag. And the mean temperature at each point appears to be different according to the materials. Therefore, the study conducted with human participants requires a proper particle size of it which would not penetrate cellular tissues and a proper binder and binding treatment for it, to prevent the physical fatigues and the potential diseases. However, it is highly required for back-up researches to verify various aspects in applying nano silver to textile products.

  • The purpose of this study was to analyze and determine the relationship between physiological responses including blood flow rate and garment pressure, and the feeling of restrictive tightness associated with the wearing skinny pants as a popular clothing style. Evaluation was based on material type, posture and activity type, and body part location. Five female college students took part in this research. Five kinds of experimental clothes with waist measurements of 66cm were chosen. An analysis of the selected skinny pants demonstrated the degree of the whole looseness was higher in this order: clothing type A>B>D>C, and E with E being knitted cloth. Garment pressure was the highest in the front knee portions and was lowest in the outside thigh region. Garment pressure was highest in this sequence : clothing type C>=D>A>=B>E. In terms of posture and activity types, garment pressure was the highest when research participants were crouching, and was the lowest when standing. The blood flow rate was highest in this order: clothing type E>D>B>A>C. Type C skinny pants impeded blood flow and demonstrated the tightest and most restrictive relationship. Blood flow rate varied depending on the type of movement and was highest in this order: getting up, rowing, kicking, jumping and O-shaped leg posture. The results of subjective pressure evaluation demonstrated that pressure was highest in this order: E>=C>B>A>D. These results suggests the need to improve on the patterns and the material design in the area of the front knees. The degree of the looseness when wearing skinny pants did not always correspond to garment pressure or subjective sensation.

  • The purpose of this study was to reveal the thermal comfort and physiological and psychological effects of spending time in broad-leaved forests in suumer. Thirty-one university students (with an average age of 21.4 ± 2.1 years) participated in the study, and a within-subjects experimental design methodology was used. The participants moved to an experimental site (with a crown closure of 76.6%) or a control site (25.9%), sat on a chair to eliminate the impact of movement, and rested for 5 minutes with closed eyes. At this time, thermal comfort, heart rate variability, heart rate, and forehead temperature were continuously measured. After that, blood pressure and pulse rate were measured, and a subjective evaluation was conducted. As a result, spending time at an experimental site showed a statistically significant decrease in the predicted mean vote and the percentage of dissatisfied values, enhancement of parasympathetic nerve activity, decrease of forehead temperature, diastolic blood pressure, heart rate, pulse rate, and improvement of personal thermal sensation (thermal sensation vote and comfort sensation vote). In conclusion, it was found that a forest with high crown closure reduces thermal stress and induces physiological and psychological relaxation.

  • In most existing research, it is difficult to evaluate thermal comfort exactly because of reflecting individual ideal or psychological response by subjective questions. Physiological variable was selected in this study to evaluate objectively thermal comfort. MST was appeared very sensitively in indoor temperature and can express correctly thermal comfort of human body. The results of CSV are different each individual feeling sensation, so is difficult to evaluate detailedly thermal comfort unlike TSV. But the results of PP, AIx, ED, SEVR are greatly related to temperature change. So thermal comfort is evaluated more objectively by using PP, AIx, ED, SEVR on behalf of TSV, CSV. Human body was presented physiological feedback by temperature impetus and specially, tendency of heart rate agree with temperature change. Physiological reaction was showed sufficient possibility availing evaluation index of thermal comfort. In the future another one needs to review beside the selected physiological variable.
