Purpose: The purpose of this study was to describe hospital nurses' knowledge and beliefs about hand hygiene and to identify the relationships between knowledge and beliefs. Methods: Data were collected from 232 nurses working in four university hospitals and were analyzed using SPSS/WIN 20.0 program. Results: The mean score of knowledge of hand hygiene was 8.1. The mean scores of behavioral, normative, and control belief about hand hygiene were 2.3, 2.5, and -0.7, respectively. Knowledge was correlated with educational level (p=.013) and experience of hand hygiene campaign (p=.018). The behavioral belief was correlated with age (p<.001) and career (p=.002). The normative belief was correlated with work department (p=.007). The control belief was correlated with educational level (p=.043) and experience of being monitored on hand hygiene (p=.010). The subjects who believed that head nurses, charge nurses, and colleagues practiced better hand hygiene had higher behavioral and normative belief scores than those who did not. There were no significant relationships between knowledge and beliefs. Conclusion: There is a need to improve knowledge of hand hygiene in hospital nurses. This study provides information for developing strategies to strengthen beliefs about hand hygiene.

Purpose: This study aimed to identify factors relating to COVID-19 knowledge and resilience that impact elementary school health teacher performance at infection control. Methods: This study adopted a cross-sectional design. Data were collected from 140 elementary school health teachers by convenience sampling. Collected data were analyzed using SPSS Ver. 26.0. Results: Mean scores were as follows COVID-19 knowledge 17.99±2.37 (range 0-23), resilience 120.36±16.90 (range 30-150), and performance at infection control 85.91±10.07 (range 25-100). A positive correlation was observed between resilience and infection control performance (r=0.57, p<.001). Factors found to influence participant performance at infection control were resilience (𝛽=0.54, p<.001) and two categories of educational experience: 11-15 years (𝛽 = 0.24, p=.011) and more than 20 years (𝛽=0.29, p=.044). Conclusion: These results indicate the resilience of elementary school health teachers positively affects their performance at infection control. Generally, both age and work experience affected ability to perform infection control. Therefore, this study supports the need to develop programs to increase the resilience of elementary school health teachers according to infection control performance and age.

The existing fuzzy traffic controllers construct the rule-base based on the intuitive knowledge and experience or the standard rule-base, but the rule-base constructed by the above methods has difficulty in representing exactly and detailedly the control knowledge of the export and the operator. Therefore, in this paper, we propose a method that can improve the performance of the fuzzy traffic control by designing the fuzzy traffic controller which represents the control knowledge more exactly. The proposed method so modifies the position and shape of the fuzzy membership function based on the input-output data clustering that the fuzzy traffic controller can represent the control knowledge more exactly. Our method use the rough control knowledge based on intuitive knowledge and experience as the evaluation function for clustering the input-output data. The fuzzy traffic controller designed by the our method could represent the control knowledge of the expert and the operator more exactly, and it outperformed the existing controller in terms of the number of passed vehicles and the wasted green-time.

The purpose of this study is to investigate the relationship between of weight control attempts with concern about weight control. nutrition knowledge, eating behavior and nutrients Intake among high school girls in Seoul, Korea. A self-administered questionnaire was distributed to 355 subjects. The subjects were then divided into two groups, one with experience in attempting to control their weight, and one with no experience in attempting to control their weight. The mean averages of height, weight. obesity index (OI) and BMI of the subjects were 161.1cm, 53.1kg, -5.2% and 20.4, respectively. 49% of the subjects were experienced in attempting weight control. The majority of the group that had experience in weight control expressed dissatisfaction of with their self body image (66.7%), and was concerned about weight control (94.9%). This group also had more abnormal eating habits than the group that had no experience in weight control attempts, such as missing meals, eating irregularly, not eating a variety of foods and snacking. The mean averages of perceived knowledge (PK) and correct knowledge (CK) regarding nutrition on a 30 point scale were 23.6 (78.7% of total score) and 15.8 (52.7%), respectively. There were no significant differences of the PK's and the CK's between the two groups. Nutrients intakes of the two groups were not significantly different and the mean nutrient intakes revealed adequate consumption of energy. protein, Fe, Ca. thiamin. riboflavin, niacin, vitamin A and C. The higher the dissatisfaction of their self body image, PK score. and abnormal eating habits, the higher the level of concerns about of being overweight.

Purpose: The purpose of this study was to develop and conduct an intensive education program on infection control and investigated how the program influenced nursing students' knowledge, attitude, and confidence in the infection control. Methods: The program was conducted for four days between January 5 and 8, 2016, for seven hours per day. The program was conducted by the specialists in infectious diseases and the nurses specializing in infection, and the third year students enrolled in E University participated in the program. Knowledge, attitude, and confidence in infection control were measured before and after the program in the students that participated in the program and those who did not. The experimental group consisted of 33 students while the control group comprised 28 students. Results: The two groups were found to be homogeneous before the education program. After four days of intensive education program, the experimental group showed statistically significant improvements in knowledge (t=2.02, p=.048), attitude (t=2.04, p=.045), and performance confidence (t=2.75, p=.008) in infection control when compared to the control group. Conclusion: The present study showed that our intensive education program on hospital infection control was effective for the nursing students who will be professional nurses who will carry out autonomous roles in infection control in a near future.

This study was designed to examine weight control, nutritional knowledge, dietary attitudes and eating behaviors of 370 high school girls and to investigate if there were differences in these variables by weight control status. The weight control attempters (65.1%) had significantly higher body weight and BMI (p<0.001). The difference between desired and current body weight was -9.1 kg in the attempters, showing a significantly higher difference than the counterparts (p<0.001). The attempters also showed more interest toward weight control (p<0.001), but were less satisfied with their body size (p<0.001). Most of subjects (88.1%), especially in the attempters (96.7%) responded that they would try to control their weights in the future. The regular exerciser was 22.9% in the attempters while the percentage of the counterparts was 11.9% (p<0.05). The use of internet or television watching was not significantly different by weight control status. Subjects scored 15.8 out of 20 on a nutritional knowledge scale, which showed a moderate level of knowledge. The nutritional knowledge score was 15.7 for the attempters and 15.8 for the counterparts. None of the nutritional knowledge items reached statistical significance, although the percentages of correct answers regarding weight control or balanced meals were slightly lower in the attempters. The attempters showed more favorable eating attitudes than the counterparts (p<0.001), especially in the attitudes of applying nutritional knowledge to daily life (p<0.01), attitudes for modifying diets (p<0.01) and importance of having adequate meals (p<0.01). The eating behavior was moderate, with mean scores of 31.1 (possible score: 15 - 45). Subjects showed problems in eating a variety of foods, eating meals regularly, eating slowly, eating breakfast and consumption of some food groups (e.g., dairy foods, fruits). The attempters consumed seaweeds more frequently than the counterparts (p<0.05). Although there were not many significant differences by weight control status, this study suggested that nutrition education for adolescent girls should be planned to provide nutrition information regarding desirable weight control as well as modifying diets and eating behaviors.

Purpose: The aim of this study was to examine the relationship between handwashing knowledge and handwashing compliance in nursing students and to identify the moderation and mediation effects of self-efficacy and perceived behavioral control on the relationship. Methods: The participants were 172 nursing college students who completed the self-report measures. Data were analyzed using t-test, ANOVA, and Pearson correlation coefficient, Multiple regression analysis was used to test moderation and mediation effects. Results: The score for knowledge of handwashing was higher in participants who had completed fundamentals of nursing practicum (t=-6.54, p<.001) and the score for compliance with handwashing was higher in participants who had completed clinical practicum (t=-3.81, p<.001) or fundamentals of nursing practicum (t=-5.97, p<.001). Self-efficacy showed a significant moderation effect (z=2.21, p=.027) but not a mediation effect while perceived behavioral control had a significant mediation effect but not a moderation effect on the relationship between knowledge of handwashing and compliance. Conclusion: Findings indicate that clinical practicum and fundamentals of nursing practicum were helpful to nursing students in acquiring knowledge and in practicing proper handwashing technique. These findings suggest that continuing and repetitive education programs on handwashing need to be enhanced and strategies to strengthen self-efficacy and perceived behavioral control need to be included in education programs.

This paper presents an effective construction method of adaptive multiple control systems utilizing some knowledge upon the plants. The adaptive multiple control system operates plants un-der widely changing environmental conditions. The adaptive multiple control system is composed of a family of candidate controllers together with a supervisor. The system does not require any identification schemes of environmental conditions. Monitoring outputs of the plant, the supervisor switches from one candidate controller to another, The basic ideas of adaptation are as follows: (1)each candidate controller is prepared for each environmental condition in advance; (2)the supervise. applies a sequence of speculative controls to the plant with candidate controllers just after the start of control or just after the detection of a change in the environmental condition. Each candidate controller can keep the system stable during one-step period of the speculative control and the most appropriate candidate controller for the environmental condition to which the system is exposed can be selected before the last trial of speculative control step comes to an end. We proposed a construction method of adaptive multiple control system without any knowledge of plant dynamics and applied the method to a cart-pole balancing problem and a vehicle anti skid braking system. In real applications, as we can often easily obtain a piece of knowledge upon plant dynamics beforehand, we intend to extend the method such that multiple control systems can be efficiently designed using the knowledge. We apply the new idea to the cart-pole balancing problem with variable length of the pole. The simulation experiments lead us to the conclusion that the new attempt can reduce the manpower to design the candidate controllers for adaptive multiple control systems.
