The purpose of this study is to weigh the students' backpacks of middle school in daily use and to analyse their physiological responses and subjective senses when carrying backpack in order to promote healthy and comfort school life of girl middle school students. Two female students were subjects who answered the questionnaires on two types of backpack and their metabolism, perspiration and the changes of skin temperature were measured in constant environment chamber, $25{\pm}1$ and $49{\pm}10$% RH. They walked on the treadmill carrying the backpack with the increment of backpack weight, 2 kg, 4 kg to 6 kg. When the backpack increases to 6 kg, the discomfort parameters and responses increases rapidly. Comparing with general type, improved type of backpack showed good results in physiological responses, but not in subjective senses, such as the ease of movement, pain, or total preference, specially in 2 kg and 4 kg. The girl students prefer the general type of backpack which is of fashion and small, when it weighs light such as 2 kg or 4 kg, while they prefer the improved bag which is functional when it is heavy as 6 kg. The longer wearing time of the medium weight, for example, 4 kg without feeling or recognition of any discomfort due to fashion style, might cause the students' posture and health weaker or more vulnerable to the problems.

Objectives： Smoking, especially among youth, has been increasing in Korea. This study was performed to evaluate the effects of a newly developing well-designed packaged smoking prevention program (PSPP) for middle school students and to propose further ideas about the program. Methods： The subjects were middle school students enrolled in one Busan city middle school. The effects of the PSPP were evaluated through intervention and follow-up. The PSPP was executed for 10 hours during the semester of middle school freshmen by the author as a position of health teacher, from 1999. After PSPP, cognitions and experiences about smoking were assessed annually from February, 2000 to 2002 by questionnaire. The responses of the educated group and the non-educated group (enrolled in the school at 1998) were compared through chi-square test and odds ratio (OR) and 95％ confidence interval (CI) using SPSS program (ver 10.0). Results： In the three years' follow-up study on the students enrolled in 1999, the proportion of habitual smoking increased significantly (p＜0.001); freshmen 0.2％, sophmore 1.7％, junior 5.0％. However, these level were lower than the results of national study； freshmen 1.1 ％, sophmorer 6.3％, junior 8.5％. Also, the risk of smoking based on the response of 'smoking is hazardous to my health' increased by higher grading. In the comparison of educated and non-educated group, the proportion of the habitual smoking was significantly lower in the educated group(5.0％) than in the non-educated group(13.5％) (OR [95％CI]＝0.33 [0.20∼0.57]). The response rate of 'smoking is hazardous to my health' was higher (OR [95％CI]＝4.42 [2.52∼7.77]), and that of 'maybe smoking in the future' was lower (OR [95％CI]＝0.43 [0.31∼0.59]) in the educated group than in the non-educated group. Conclusions： Though there is not enough information and it was a relatively short evaluation period, this PSPP is considered to be effective in smoking prevention in middle school students. Interests and continuity would be emphasized for the success of smoking prevention programs for younger subjects.

The units about electricity in 5th and 6th science curriculum for elementary school was analyzed and the elementary students' understanding of related concepts was investigated. This study was to make connection between the research about alternative concepts and writing textbooks. It was found that students' response had following characteristics. They had strong belief that the + and - ends of battery should be connected. However this belief was not complete because students did not understand that the other circuit elements had to be connected properly. When the circuit involve more than one bulbs or batteries, they counted the number of batteries or bulbs only and paid little attention to the connection of them. In explaining circuits and the brightness of the bulbs in the circuits. students tried to explains the circuit using scientific terms but failed to used them properly. Although the concept of resistance was not dealt explicitly. student had reasonable qualitative understanding about resistance. According to response of students, several suggestions might be made for the curriculum. The structure and the circuit elements and the proper connection needs to be taught. Also more emphasis is necessary to pay attention to the connection in addition to the numbers of bulbs or batteries. Finally, it needs to be investigated carefully if it is better to introduce some qualitative model to explain the amount of current through bulb depending on the connection and the number of bulbs. It might also be better to introduce some terms, such as current and resistance with the model.

Purpose: As coronavirus disease 2019 (COVID-19) and other emerging infectious diseases continue to threaten health security, a strategy is required to increase nursing students' care intention for patients with such diseases. This study aimed to identify factors influencing Korean nursing students' care intentions in regard to patients with emerging infectious diseases. Methods: The care intention, COVID-19 knowledge level, ethical sensitivity, beliefs, attitudes toward the care intention, subjective norms, and perceived behavioral control were investigated using the theory of planned behavior. An online survey was completed from December 2020 to January 2021 by 227 nursing students who had complete a clinical practicum. Descriptive statistics, correlation, and hierarchical regression analyses were conducted on the data. Results: The care intention was higher in men than in women nursing students and in junior than in senior students. Behavioral and normative beliefs, attitude toward the behavior, and perceived behavioral control significantly predicted care intention. Ethical sensitivity increased the predictability of nursing students' care intentions for emerging infectious disease patients. Conclusion: The theory of planned behavior predicted nursing students' care intentions for emerging infectious diseases. Therefore, an experience-based response program on emerging infectious diseases is required for nursing students.

Purpose: The purpose of this study was to evaluate the nursing students' clinical judgment skills in simulation using Tanner's Clinical Judgment Model. Method: Forty-five teams of a total 93 nursing students participated in a post-operative patient care scenario using human patient simulator. Data were collected from students' responses in scenario and guided reflective journaling according to the framework of Tanner's model which comprised noticing, interpreting, responding, and reflecting on response. Data were analyzed using descriptive statistics. Results: The students' responses of the situation were in accordance with the goals of scenario, i.e. relieving patient' pain and preventing pulmonary complications. However, most of students needed clinical cues and focused on a given clue to solve the issues. They were lack of ability to collect additional information as well as connect the relevant clues in simulated clinical situation. Conclusion: The nursing students have difficulty in what they notice, how they interpret finding, and respond appropriately to the situation. The simulation training using Tanner's model could provide faculty and nursing students with an effective teaching and learning strategy to develop the clinical judgment skills.

Elementary science curriculum is designed to be closely-related magnetism with electricity in a physics domain and this paper explored whether elementary school students have recognized of relationships between them and whether there are any trends in the degree of recognition by grades. The elementary students of 3rd to 6th grade (total 154 persons) in a school in a local city participated in the experiment. Two forms of questionnaire were administrated to each grades. In the first questionnaire about magnetism, students were asked to rank the physics terms as the degree of proximity into magnetism and to write briefly the reason. In the second questionnaire about electricity, students were asked to do the same routine. The closer to the central term in the diagram, the lower score were given and the terms were classified as closely related to magnetism, electricity and the rest. Calculated the response frequency and averaged by the ranked terms, it was examined that the scores of proximity in how students closely rated conception to magnetism and electricity. The result said that the upper grades students showed the degree of proximity with magnetism and electricity as closely. Therefore, the sequence of comprehension of magnetism and electricity concept, which was found in the elementary school curriculum, seems to be found in the elementary students＇ recognitions by grades.

In this study, students' performances on the reasoning tasks dealing with physical situations were analyzed. Through these analysis, the influences of students' preconceptions and logical abilities in reasoning process were described. For this study, 97 high school students were randomly selected. Among them, the number of the students who changed their misconceptions is 62% for the first task(force acting on the upward moving body), and 25% for the second task(force acting on the body when it is on the top of its motion). The students who show the premise-based response changed their conceptions in both of the tasks are more than those who responded in the idea based responses. The index of the influence of prior knowledge, ${\alpha}$ is 33% for the first task, and 67% for the second task, and ${\beta}$ is 41% for the first task, and 17% for the second task. When students performed the reasoning tasks about force and motion, the misconcepts frequently influenced their performances. But for the first task, the precentage of students who changed their concepts is about 62%. It shows the possibility that if the task is simple and appropriate, students can change their concepts.
