The objective of this study was to analyze the accuracy of estrus detection of heat detector and analysis of estrus behavior (mounting and mounted), and the evaluation of conditions required for improving reproductive efficiency in Holstein dairy cows fitted with a estrous detector. The heat detection system consists of estrous detector based on wireless sensor and an electric bulletin board displayed estrus behavior data. When cow mounting other cows, the accuracy of estrus behavior displayed an electric bulletin board were 87.5% (mounting other cows only), 100% (mounting other cows but not standing), 80.0% (mounting other cows with standing for 1~4 seconds), 90.0% (mounting other cows but not standing for 1~4 seconds), 80% (mounting other cows with standing for more than 5 seconds) and 90.0% (mounting other cows but not standing for more than 5 seconds). When cow mounted other cows, the accuracy of estrus behavior displayed an electric bulletin board were 100% (mounted other cows but not standing), 100% (mounted other cows with standing for 1~4 seconds), 100% (mounted other cows but not standing for 1~4 seconds) and 100% (mounted other cows with standing for more than 5 seconds). Circadian distribution of first observed in estrus were 59.1% (am 8~pm 6) and 40.9% (pm 6~am 8). Distribution for the number of estrus behavior were 40.9% (less than 3 times), 36.4% (4~6 times) and 22.7% (more than 4 times). The conception rates relative to interval from first estrus behavior to insemination for estrus periods were 23.1% (less than 11 hours) and 55.6% (12~20 hours).

In this study, a survey was carried out on 300 students in Korea Culinary Arts Science High School located in Gyeonggi-do from August 1 to August 30, 2011 to figure out how the control of high school students' eating behavior affects the change of their psychological achievement. Analysis showed that attitude toward eating behavior, and perceived behavior that recognize this and act, as eating habits for control of their eating behavior, are the most control factors of eating behavior. It says that the right perception of customary attitude and the correction of habits according to the exposure and performance of repetitive eating behaviors are important. Consequently, an ordinarily regular norm as a social norm, or a rule around it won't act as big positive factors.

The purpose of this study was to identify the effect of structured patient education on knowledge and behavior about selfcare in hemodialysis patients, and to find the strategy to promote their selfcare behavior. In conclusion, structured patient education in hemodialysis patients was improved the level of knowledge and behavior about selfcare. But there was a little relationship between the knowledge and behavior about selfcare. That is ; structured patient education is the effective nursing intervention to improve their selfcare knowledge and behavior. but further research is needed to find the factor to increase selfcare behavior in hemodialysis patients.

As the population of persons over the age of sixty-five is rapidly growing, the population of solitary senior person living at own home is growing in Japan. This situation has caused the social issue of how supports their healthy life. There have been some projects related to improve their quality of life and support their healthy life. Unfortunately mostly they focus the method of measuring vital signal and observing behavior. Nobody reports how utilize the measured data. Aim of our project is how find emergency of the aged people at home. As emergency is big different from regular life behavior, we have to recognize it. We propose concept of the human behavior model and show the some types human behavior knowledge constructed by observed human behavior model and show the some types human behavior knowledge constructed by observed human behavior. This idea is based on human having habitual life. And we discuss the possibility of finding emergency using knowledge and observed data.

Purpose: This study was done to identify fundamental data on competency reinforcement programs to prevent adolescent risk behavior by developing and examining a competency model. Methods: In this study, competences on prevention of adolescent risk behavior were identified through competency modeling, and a competency model was developed and tested for validity. Results: Competences for prevention of adolescent risk behavior defined by the competency model included the following: self-control, positive mutual understanding between parents and adolescents, and positive connectedness with peer group. Validation of the competency model showed the model to be appropriate. Conclusion: The competency model for prevention of adolescent risk behavior through competency modeling is expected to be the foundation of an integral approach to enhance competency in adolescents and prevent adolescent risk behavior. This kind of approach can be a school-centered, cost-efficient strategy, which not only reduces adolescent risk behavior but also improves quality of adolescent resources.

Purpose: This study was a descriptive survey study to examine the degrees of the health perception, health knowledge, and health promoting behavior in the elderly, and the relationship among the above factors. Methods: Subjects were 183 persons with the age over 65 years living in Seoul. Measures were Health Perception Questionnaire (HPQ) developed by Ware (1979), the health knowledge instrument developed by Ha Gwi-Yeom (2005), and the Health Promotion Lifestyle Profile (HPLP) developed by Walker, Sechrist & Pender (1987) and modified by Hong Young-Ae (2003). Data were collected from March 4 to April 12, 2007. Data were analyzed by frequency, percentage, mean, standard deviation, t-test, ANOVA, Pearson's correlation using the SPSS program. Results: The mean level of health perception was 2.71(${\pm}0.77$), the mean level of health knowledge was 7.10(${\pm}1.82$), and the mean level of health promoting behavior $2.72{\pm}0.86$. Health promoting behavior showed a positive correlation with health perception (r=.715) and health knowledge (r=.543), and a positive relation was observed between health perception and health knowledge (r=.526). Conclusion: The enhancement of health perception and health knowledge are needed to improve health promoting behavior of the elderly. Also, the general characteristics of elderly should be considered to improve health promoting behavior of elderly.

Feeding is the most important behavior that represents the health and welfare of weanling pigs. The early detection of feed refusal is crucial for the control of disease in the initial stages and the detection of empty feeders for adding feed in a timely manner. This paper proposes a real-time technique for the detection and recognition of small pigs using a deep-leaning-based method. The proposed model focuses on detecting pigs on a feeder in a feeding position. Conventional methods detect pigs and then classify them into different behavior gestures. In contrast, in the proposed method, these two tasks are combined into a single process to detect only feeding behavior to increase the speed of detection. Considering the significant differences between pig behaviors at different sizes, adaptive adjustments are introduced into a you-only-look-once (YOLO) model, including an angle optimization strategy between the head and body for detecting a head in a feeder. According to experimental results, this method can detect the feeding behavior of pigs and screen non-feeding positions with 95.66%, 94.22%, and 96.56% average precision (AP) at an intersection over union (IoU) threshold of 0.5 for YOLOv3, YOLOv4, and an additional layer and with the proposed activation function, respectively. Drinking behavior was detected with 86.86%, 89.16%, and 86.41% AP at a 0.5 IoU threshold for YOLOv3, YOLOv4, and the proposed activation function, respectively. In terms of detection and classification, the results of our study demonstrate that the proposed method yields higher precision and recall compared to conventional methods.

The effect of cooling rate on the solidification microstructure and segregation behavior of 7075 and 7050 aluminum alloy was investigated. Samples were solidified with cooling rates from 0.3 to $17^{\circ}K/sec$. Using the cooling curves of each sample, liquidus, eutectic and intermetallic reaction temperatures were estimated. The microstructures were characterized in terms of dendrite arm spacing and eutectic volume fraction. The segregation behavior of each alloying element of these alloys in various cooling rates was discussed.

Recently, some research has been done to analyze the asymptotic behavior of queue length distribution in ATM (Asynchronous Transfer Mode) multiplexer. In this paper, we relate this asymptotic behavior with the asymptotic behavior of decreasing cell loss probability when the buffer capacity is increased. We find with reasonable assumptions that the asymptotic rate of queue length distribution is the same as that of decreasing cell loss probability. Even under different priority control schemes and traffic classes, we find that this asymptotic rate of the individual cell loss probability of each traffic class does not change. As a consequence, we propose the upper bound of cell loss probability of each traffic class when a priority control scheme is employed. This bound is computationally feasible in a real-time. The numerical examples will be provided to validate this finding.
