1. Modifications were made to the 65MN thermoregulation model : 1) Modeling of AVA veins that become effective under hot climatic conditions, 2) Modeling of body size and age differences to enable simulation of the young to the elderly, males and females, 3) Modeling of moisture transport in the clothing layer. Subjective experiments were conducted under transient thermal conditions to validate the accuracy of the models. The developed model, REAL was able to reproduce similar results to the subjective experiment.2. A new analysis method was proposed to simulate the detailed heat exchange between thermal manikin and the surrounding thermal environment from the results of the experiments in an atrium where all the thermal parameters were known. Subjective experiment was conducted in the same atrium and results were compared with the combined analysis of thermoregulation model and CFD. The model was able to reproduce similar results with the subjective experiment within 1℃ difference in mean skin temperature. Differences tended to be larger in the extremities than in the trunk.3. Specifications of thermal measurement device were proposed to evaluate transient and asymmetric thermal environment. Mobile measurement cart with all-wave (0.3-40μm) radiometers was developed. Weighting factors of six directional radiations for seated and standing human bodies were proposed and compared with the earlier studies.4. Effects of lumbar skin warming on gastric motility, blood pressure, and diameters of the abdominal arteries were examined in healthy college students. The results showed that changes in gastric blood flow due to vasoconstriction and following vasodilatation by lumbar skin warming activates interdigestive migrating motor complex, although a possibility of vasoconstriction preceding vasodilatation is still to be explored.

1.对65 MN体温调节模型进行了修改：1）在炎热气候条件下有效的AVA静脉建模，2）体型和年龄差异建模，以模拟年轻人到老年人，男性和女性，3）服装层中的水分传输建模。在瞬态热条件下进行了主观实验，以验证模型的准确性。所开发的模型真实的能够重现与主观实验相似的结果。提出了一种新的分析方法，在已知所有热参数的前提下，通过中庭实验结果来模拟暖体假人与周围热环境之间的详细热交换。在同一个中庭进行了主观实验，并将实验结果与温度调节模型和CFD的联合分析结果进行了比较。在平均皮肤温度相差1℃的范围内，该模型能够再现与主观实验相似的结果。四肢的差异往往大于躯干。提出了瞬态非对称热环境热测量装置的技术指标。研制了一种移动的测量车，它装有全波（0.3-40μm）辐射计。提出了人体坐姿和站立时六个方向辐射的权重因子，并与以往的研究进行了比较.在健康大学生中研究了腰部皮肤温热对胃动力、血压和腹部动脉直径的影响。结果表明，胃血流量的变化，由于血管收缩和以下血管扩张的腰部皮肤温暖激活消化间期移行性运动复合体，虽然血管收缩之前的血管扩张的可能性仍有待探讨。
