Objectives & Methods: This suggestion was attempted to be elevated the recognition of common characteristics in disease. So, we performed to analyze the correlation of common cause of disease, characteristics of human body, and medical treatment. And the results are as follows. Results: 1. The cause of disease is consist of genetic factor, aging, habit, food of not good in health, weather, environment, deficit of the physical activity, stress and so on. 2. Generally, human has common and individual weakness. Individual weakness is appeared similar to the occurrence of volcano and lapse. 3. The correlation of disease and medical treatments is possible to explain using the quotation of the law of motion made by Isaac Newton, the great physicist. 4. When the process of the medical treatment was not progressed, the prognosis is determined by the correlation of the homeostasis(H') in human body and the homeostasis(H) of disease. 5. The prognosis of disease is determined by the relationship between the energy of disease(F) and medical treatment(F'). 6. The exact diagnosis is possible to predict the treatment sequence, and the facts that homeostasis in human body and disease, relationship between the energy of disease(F) and medical treatment(F'), action and reaction are important to determine the prognosis. 7. The careful observation of improving response and worsening action of disease becomes available for exact prognosis. Conclusion: The above described contents may be useful in clinical studies, and the concrete clinical reports about this will be made afterward.

Operator's action time is evaluated from MAAP4 analysis used in conventional probabilistic safety assessment(PSA) of a nuclear power plant. MAAP4 code which was developed for severe accident analysis is too conservative to perform a realistic PSA. A best-estimate code such as RELAP5/MOD3, MARS has been used to reduce the conservatism of thermal hydraulic analysis. In this study, operator's action time of core cooling recovery operation is evaluated by using the MARS code, which its Fussell-Vessely(F-V) value was evaluated as highly important in a small break loss of coolant(SBLOCA) event and loss of component cooling water(LOCCW) event in previous PSA. The main conclusions were elicited : (1) MARS analysis provides larger time window for operator's action time than MAAP4 analysis and gives the more realistic time window in PSA (2) Sufficient operator's action time can reduce human error probability and core damage frequency in PSA.

This paper presents a new approach to the evaluation of an accident management strategy when an operator action is involved. This approach classifies the failure in implementing a given strategy into 4 possible mechanisms, and provides their corresponding quantification methods : 1) the failure to formulate correct intention by operators, 2) the failure to take an adequate action following a correct diagnosis, 3) the failure of a system operation following an adequate action, and 4) the failure due to a delayed action. The proposed method was applied to assess a cavity flooding strategy that uses containment spray system (CSS), and the result shows that the method is more appropriate in evaluating accident management strategies when human action is involved.

In this paper, we present a real-time cattle action recognition algorithm to detect the estrus phase of cattle from a live video stream. In order to classify cattle movement, specifically, to detect the mounting action, the most observable sign of the estrus phase, a simple yet effective feature description exploiting motion history images (MHI) is designed. By learning the proposed features using the support vector machine framework, various representative cattle actions, such as mounting, walking, tail wagging, and foot stamping, can be recognized robustly in complex scenes. Thanks to low complexity of the proposed action recognition algorithm, multiple cattle in three enclosures can be monitored simultaneously using a single fisheye camera. Through extensive experiments with real video streams, we confirmed that the proposed algorithm outperforms a conventional human action recognition algorithm by 18% in terms of recognition accuracy even with much smaller dimensional feature description.

Skeleton-based action recognition has attracted considerable attention in human action recognition. Recent methods for skeleton-based action recognition employ spatiotemporal graph convolutional networks (GCNs) and have remarkable performance. However, most of them have heavy computational complexity for robust action recognition. To solve this problem, we propose a shuffle graph convolutional network (SGCN) which is a lightweight graph convolutional network using pointwise group convolution rather than pointwise convolution to reduce computational cost. Our SGCN is composed of spatial and temporal GCN. The spatial shuffle GCN contains pointwise group convolution and part shuffle module which enhances local and global information between correlated joints. In addition, the temporal shuffle GCN contains depthwise convolution to maintain a large receptive field. Our model achieves comparable performance with lowest computational cost and exceeds the performance of baseline at 0.3% and 1.2% on NTU RGB+D and NTU RGB+D 120 datasets, respectively.

The avian pineal as well as the retina has been known to contain several types of photoreceptors with different visual pigments such as rhodopsin, iodopsin and the pineal specific opsin, pinopsin. These organs are also known to have circadian clock to regulate melatonin production. Exposure of animals to light causes a decline of the melatonin level and the phase shifts of melatonin rhythms in the pineal and retina. Therefore, the circadian clock system of these organs seem to consist of three elements, i.e., light input, oscillator and melatonin output systems. In birds, it was suggested that rhodopsin might be involved in the entrainment of pineal melatonin rhythms from the action spectrum experiment for controlling NAT activity rhythms. However, there are much more pinopsin-immunoreactive (Pino-IR) cells than rhodopsin (Rho-IR) and iodopsin (Iodo-IR) cells in the avian pineal. We found that Pino-IR cells appeared earlier embryonic stages than Rho-IR and Iodo-IR cells. So, we tried to identify the visual pigments involved in the circadian melatonin rhythms in the pineal and retina. Organ cultured pineals were exposed to monochromatic light to find out which opsin participates in regulation of melatonin rhythms. The action spectra showed a peak at 475nm, suggesting that pinopsin is the major photopigment to regulate melatonin production in birds.

The objectives of this study were (1) to determine the rank of purposes of Korean secondary school home economics education related to three systems of action: technical, communicative, and emancipatory action by home economics(HE) teachers and HE teacher educators, (2) to compare differences between HE teachers and HE teacher educators concerning the degree of importance and achievement of the purposes of current Korean secondary school HE education. Respondents in this study were 225 HE teachers and 35 HE teacher educators. The survey method was used in this descriptive study. To determine the rank, Borich's needs assessment model was used. The data were analyzed by using t-test to compare the differences between the two groups. To promote a good life and the full development of human beings, to develop creative and critical thinking, to make morally defensible judgments, and to develop self-esteem were needed purposes for Korean secondary school HE education. Overall, the most high ranked purpose needs for both groups related to emancipatory action. The two groups were significantly different on the degree of the importance of evaluating family and social conditions, acquiring the skills needed as a wage earner and a homemaker, developing creative and critical thinking, and demonstrating proficiency of homemaking work. The teachers and teacher educator groups were significantly different on the degree of the achievement of making morally defensible judgments, understanding Korean traditional culture, and taking care of each other.

The etymological meaning of 'the Picturesque' is "after the manner of painters." It had begun to be used from the end of Classical era and become popular in Romantic era. The concept of the Picturesque in the Classical era is an allusion to the Classical paintings, history paintings or ideal landscapes. As the idea of these paintings was the Beautiful Nature, the most crucial of the Classical Picturesque were that a painting should represent some significant human action; that all the parts of this painting should contribute to the whole; that verbal commentaries were needed. The influence of the Picturesque on the garden design can be summarized as the invention of 'the Landscape Garden.' In the Landscape Garden, human action was central and formal and painterly techiniques were used to highlight human action. The subjectivization of concept of of the beauty resulted in the cult of the Picturesque. In the controversy by Price and Knight, the Picturesque and its influence on the garden design was contended variously. Price criticized the monotonous gardens of Brown's and named "roughness, sudden varitation and irregularity" as the three hallmarks of the Picturesque. Knight contended " that the Picturesque consisted only in a manner of viewing things with an eye and mind educated in the principles of painting" and "that gardens should reproduce as fully as possible the qualities that made the pictures of Rosa or Hobbema delightful."

This study was to examine home economics (HE) teachers' and the 1st-grade students' needs perception toward the purposes of HE education in middle school which has been practced since 1995 for both male and female students. This study, attempted (1) to analyze needs priority among the educational purposes of HE subject in relation to three systems of actions; (2) to compare differences between HE teachers' and students' perception concerning the degree of importance and achievement of the educational purposes of HE subject: and (3) to examine what they conceive as the problems In the current HE education. The survey was conducted with the samples of 600 1st-grade middle school students and 101 middle school HE teachers during the period of February-March 1996. The questionnaire used in this study was a modified version which had already been developed along with the 6th HE curriculum. For data analyses, SAS program was utilized to get Means and to perform both discrepancy test and t-test. The findings of this study were summarized as follows: first, with respect to each group's perception of the importance of the purposes related to three systems of action, HE teachers emphasized the importance of the purposes related to emancipatory action, while students placed more emphasis on the purposes related to technical action. Second, in terms of the degree of achievement, students had more positive perception on the degree of achievement of the purposes related to technical action than HE teachers did. Both groups marked low level of recognition on the degree of achievement of the purposes related to emancipatory action. Third, with respect to needs priority, HE teachers placed the first priority on emancipatory action, the second on technical action, and the last on communicative action: in the case of students, the first priority was on technical action, the second on communicative action, and the last on emancipatory action. In addition, the analysis of the opinions on the 6th curriculum revealed that most respondents found it necessary to secure adequate amount of classes for HE education. Also they shared the recongnition that HE curriculum should be renovated into the one which would fully appreciate the purposes of HE education from the perspective of the practical concerns of action which are distinct from the functional and technical concerns of passive learning. The findings of this study can serve as basic data for establishing the new purposes of HE education which put more emphasis on the purposes related to emancipatory action: as well as for developing an enhanced curriculum and reinforcing the identity of HE education.

Phospholipids were examined for their capacity to protect human erythrocytes against hemolysis induced by hypotonic solution, p-hydroxymercuribenzoate or hematin. The following results were obtained. 1. Phosphatidyl choline, lysophosphatidyl choline and phophatidyl ethanoleamine as well as chlorpromazine prevented the osmotic hemolysis of human erythrocytes which occurred due to water influx into erythrocytes from medium, but showed no effect on hematin-induced hemolysis which occurred without the volume change of erythrocytes. 2. Human erythrocytes were found to be most sensitive to the antihemolytic action of phospholipids among mammalian erythrocytes from sheep, rabbit, rat and mouse. 3. Phospholipids at the concentrations showing their strong antihemolytic effect on human erythrocytes against osmotic hemolysis had no influence on methylene blue uptake and volume change of erythrocytes in hypotonic solution. 4. Phospholipids increased erythrocyte deformability 2 to 3 times over control group and there was aclose relationship between their antihemolytic action and increase of deformability as a function of their concentrations. 5. The phospholipids increased the resistance to osmotic hemolysis of human erythrocytes by increasing membrane elasticity through their incorporation into lipid bilayer without altering glucose metabolism and water influx to erythrocytes.
