Railroad shunting movements connecting and disconnecting train sets are very susceptible to human errors since they depend on human decision-making and action procedure that are variable to situation to situation. Nevertheless, in the investigation of railroad accidents, all the accident causes related with human factors have merely been categorized as 'careless treatment' of the workers without any systematic approach of behavioral sciences or the analysis of human errors. In this research, therefore, 137 accident cases occurred during railroad shunting movements and 435 accident cases occurred during driving were analyzed with a special interest of human errors. According to results, the traditional accident investigation scheme used for last several decades did not seem to be appropriate for catching up true accident causes with respect to human errors. In addition, both signal men and locomotive drivers made many mistakes in judgement/action stage while the former mainly commit judgement tasks where as the latter mainly commit cognition tasks. Ant those tasks such as 'confirmation of signal and route', 'location check-up of connected train sets', and 'route identification for a shift of track' ranked highly for accident susceptibility.

The study was performed to investigate the inhibitory action on the growth rate of Candida albicans under the various immunological conditions, Candida albicans was grown in broth media containing 0.1ml. (in total broth volume 4.0ml.) of normal human serum, diabetic patient serum, albumin solution, artifical bulla content and nutrient solution as control subject. The inhibitory action of Candida albicans was indicated by mesurement of transparency rate with use of the spectrophotometer. The results are as follows: 1. Normal human serum shows inhibitory effect on the growth of the candida distinctly. 2. Albumin solution reveals almost similar to that of the effect of normal human serum. 3. Artificial bulla content which obtained by irradiation of ultraviolot ray after application of 1% 8-Methoxy-psolaren cream and the diabetic patient serum shows reduction of inhibitory effect as compared with that of the normal human serum. 4. It is estimated that the titer of negative effect of diabetic patient serum is not related with the variation of immunoglobulin titer in patient serum.

Senile involution is divided into two classes : physiological senile involution and pathological senile involution. Physiological senile involution is a natural process of vital action of decreasing Vital Essence and Energy in kidney that is a necessary physiological phenomenon. Pathological senile involution is an evidence of impairment of True Qi of internal human body. Human vital action is a changing process of life, senility, sickness, and death. In other words, this is a natural process of being full and decreasing of Vital Essence and Energy in kidney, and True Qi of human body decides this process. The Vital Essence and Energy in kidney vary, and they are influenced and restricted by various elements. The time of a senile involution varies individually. Human body protects and makes efforts not to leak out True Qi in effective ways. We can postpone a limit of time of physiological senile involution phenomenon. This is called 'Health Preservation' - resistance against senile involution.

Human uses sight, tactile sense to evaluate Total Hand Value(FUUAI) of textile fabrics. Tactile sense is important factor which decided the Total Hand Value of a textile fabric. When human feels the FUUAI, physical and physiological phenomena are occurred in finger. We first found out physical variable that is happened in fingertip when human is feeling the FUUAI. Such physical variable means characteristic of action tactual motion of finger such as moving range, tactile time, moved distance, speed of finger and applied force by finger. We study the relationship between action tactual motion and the ability in which the human distinguishes the textile fabric. As a result, we could know the characteristics of the tactual motion of fingertip to get high distinguishable ability. The characteristics were different in men and women respectively. In the case of man, touched time and moving range influenced to distinguish, and moving range, and the moving speed of finger influenced, in woman's case.

This paper presents a new dynamic human reliability analysis method and its application for quantifying the human error probabilities in implementing management action. For comparisons of current HRA methods with the new method, the characteristics of THERP, HCR, and SLIM-MAUD, which are most frequency used method in PSAs, are discussed. The action associated with implementation of the cavity flooding during a station blackout sequence is considered for its application. This method is based on the concepts of the quantified correlation between the performance requirement and performance achievement. The MAAP 3.0B code and Latin Hypercube sampling technique are used to determine the uncertainty of the performance achievement parameter. Meanwhile, the value of the performance requirement parameter is obtained from interviews. Based on these stochastic obtained, human error probabilities are calculated with respect to the various means and variances of the things. It is shown that this method is very flexible in that it can be applied to any kind of the operator actions, including the actions associated with the implementation of accident management strategies.

The purpose of this is to understand the concept of Sacho on the basis of 'Sa-Sang philosophy(四象哲學)'. In oder to achieve this purpose, Sanjiao and Sacho were investigated, centering on the philophicalbasis, region. action. The conclusion would be summerized as follows. 1. Viewed in the light of a philosophical basis, Sanjiao is first recorded in Nae-Kyung(內經), a concept that Yin-Yang(陰陽), Oh-Hang(五行) in Nae-Kyung Medcine, the cosmos's order and it's moving rule could be directly applied to human body. On the contrary Sacho is a term first used by Lee Jae-Ma, a human-oriented concept that formed in Confucianism system. based on Sa-Sang type classifying in Sa-Sang Medicine. 2. Viewd in the light of a region, the upper part of Sacho is similar to the upper-jiao of Sanjiao, the mid-upper part of Sacha to the middle-jiao of Sanjiao, the mid-lower and the lower parts of Sacha to the lower-jiao of Sanjiao. But these regions are not equal to anatomical regions. Sanjiao and Sacha is similar concept from the view point of the upper and lower oder, but Sanjiao has only a concept of the upper and lower order, doesn't have a concept of the front and the rear, inside and outside. 3. Viewed in the light of a action, Sanjiao and Sacho is a similar concept from the view point of a large boundary in the life activity.Sanjiao explains the region of human body, setting imfortance on the viscera physiology, on the contrary Sacho explains the whole function of human body including one's heart's desire, physical constitution and the visceral physiolosy. 4. Viewed in the light of produsing-wasting activity. sanjiao and Sacho have both produsing action and wasting action. but Sacho has a more concrete concept of produsing action by using a term-Sa Hae(四海) 5. Viewed in the light of vital energy(氣)'s action, Sajiao give the first consideration to the rising and falling action of vital energy, on the contrary Sacho give the first consideration to the transversal circulation of vital energy and the deviation of it in each part. According to the above results, Sacho must be discussed separately from Sanjiao, it is recommended that further study is necessary to understand the concept of Sacho on the basis of Sa-Sang philosophy.

In Oriental medicine, Five Mental is a concept for understanding of man's mental structure. Spirit and body is inseparable relation in Oriental Medicine. Function of spirit and body is regarded as one in Oriental Medical physiology. Spirit is the essence of a function which an organism reveal, and it is regarded in the same with life. For this reason, identification spirit with life is special feature of Oriental Medicine. In Confucianism, Li(理) refers to nature's discipline, which everything under the sun shares. It is similar to the concept of Shin(神) in a broad sense and Sung(性) is similar to that of Shin(神) in a narrow sense. Confucianism's principle is similar to Oriental medicine's, in that they classify Sung(性) into Gi-Jil-Ji-Sung(氣質之性) and Bon-Yeon-Ji-Sung(本然之性), that Sung(性) acts upon man differently according to his disposition, and that materials have an effect on Shin(神)'s action. According to mind's action, there are Human mind(人心) and Moral mind(道心). Human mind(人心) is defined as a mental action of higher degree and Moral mind(道心) is conceived as a mental action related to body. It is similar to Oriental medicine's principle in which Shin(神) is classified into Hun(魂) and Beak(魄) according to its action. Yi(意) is self-control and application, and Zhi(志) is a conscious state in which basic acts towards the object are fixed regularly. Those are similar to the concepts of Oriental medicine.

Bag of visual words is a popular model in human action recognition, but usually suffers from loss of spatial and temporal configuration information of local features, and large quantization error in its feature coding procedure. In this paper, to overcome the two deficiencies, we combine sparse coding with spatio-temporal pyramid for human action recognition, and regard this method as the baseline. More importantly, which is also the focus of this paper, we find that there is a hierarchical structure in feature vector constructed by the baseline method. To exploit the hierarchical structure information for better recognition accuracy, we propose a tree regularized classifier to convey the hierarchical structure information. The main contributions of this paper can be summarized as: first, we introduce a tree regularized classifier to encode the hierarchical structure information in feature vector for human action recognition. Second, we present an optimization algorithm to learn the parameters of the proposed classifier. Third, the performance of the proposed classifier is evaluated on YouTube, Hollywood2, and UCF50 datasets, the experimental results show that the proposed tree regularized classifier obtains better performance than SVM and other popular classifiers, and achieves promising results on the three datasets.

For effective conceptual teaching (or teaming) of physics, it needs to know more information about students＇ ideas related to specific topics. The purpose of this study was to investigate 6th grade students＇ various ideas about the actions of force, especially＇ the situation where force is being acted＇, and＇ the situation where force is not being acted＇, through the analysis of their ＇Typically-Perceived-Situation (TPS)＇. The TPSs of 152 6th grade students were collected with a drawing-and-explanation type questionnaire, and their TPSs about the action of force were categorized by the background, the subject, the object, the action, and the result of action, etc. It was found that most of students＇ ideas about ＇force is being acted＇ were related to the situation where the impact by or on human body caused to the change of position in familiar everyday life scene. Thus their ideas were strong related to human body, including sensual factors such as ＇pain＇. And it also was found that most of students＇ ideas about ＇force is not being acted＇ were in a strong relation to familiar everyday life situations there is no change of position because force was not given by a human body, or energy was not supplied. Most students thought that force is similar to energy which should be supplied from outside or generated by itself. These results suggest that the teaching strategies focused on familiar everyday life background including sensual factors and human body need to be explored in conceptual loaming of physics.

Wrestling is one of the popular events for modern sports. It is difficult to quantitatively describe a wrestling game between athletes. And deep learning can help wrestling training by human recognition techniques. Based on the characteristics of latest wrestling competition rules and human recognition technologies, a set of wrestling competition video analysis and retrieval system is proposed. This system uses a combination of literature method, observation method, interview method and mathematical statistics to conduct statistics, analysis, research and discussion on the application of technology. Combined the system application in targeted movement technology. A deep learning-based facial recognition psychological feature analysis method for the training and competition of classical wrestling after the implementation of the new rules is proposed. The experimental results of this paper showed that the proportion of natural emotions of male and female wrestlers was about 50%, indicating that the wrestler's mentality was relatively stable before the intense physical confrontation, and the test of the system also proved the stability of the system.
