In this paper, we present our implementation of the direct camera model (image to ground) for SPOT5 and use it to assess the geometric accuracy of SPOT5 imagery. Our assessment confirms the location accuracy of SPOT5 imagery (without use of GCPs) is less than 50m. We further introduce a few attitude parameters to refine the camera model with GCPs. The model is applied to two SPOT5 supermode images, one near vertical, incidence angle of 3 degrees, and one far oblique, incidence angle of 27 degrees. The results show that accuracy (rms of check points) of about one pixel (2.5m) can be achieved with about 4 GCPs by using only 3 parameters to correct the yaw, pitch and roll of the satellite.

The purpose of this study is to construct a structural equation model and to analyze causal relationships among variables related to attitudes to science using structural equation modeling(SEM) with LISREL VII. The sample consisted of 483 10th grade boys from a general high school in Pusan, Korea. The questionnaires (ABC-attitude scale: affection, behavioral intention, cognition scale of attitude towards science) were developed by the researcher through a pilot study. And other instruments have modified previous ones. Five instruments were used in this study: GALT(group assessment of logical thinking), MTSlS(modified test of science inquiry skill), ABC-attitude scale, MSAS(modified scientific attitude scale), CSAT(common science achievement test). Structural equation modeling with LISREL VII($J\ddot{o}reskog$ & $S\ddot{o}rbom,$ 1993) was employed to estimate the causal inferences about hypothesized relationships among observed data sets. Three competing models consisted of five latent variable(scientific thinking ability, science inquiry skill, attitude towards science, scientific attitude, science achievement) - lP(inquiry preceding) model, AP(attitude preceding) model and AM(attitude mediating) model - were developed. Among these competing models, IP model satisfied the observed data sets. The causal relationships among "attitudes to science" and other latent variables were reliably identified. According to the results of the present study, science inquiry skill was the most significant variable that can predict science achievement. But scientific thinking ability has not directly influenced science achievement. This study suggests that inquiry based teaching-learning processes should be offered to students for improvement of science achievement. At the same time, it seems to be important to develop positive attitude towards science. Understanding of relationships among variables related to attitudes to science will be helpful to the development of science curriculum and to the design of science teaching and learning process. LISREL has been recognized as a useful approach in testing a SEM. However, in this study, LISREL approach was estimated as much more useful method for research design.

This study proposed a method of accessment for traffic flow on roads based on the driver's decision making. In order to, an attempt is carried out to express driving speeds through driver's congnitive language theoretically and experimentally. Membership function is derived to express driver's congnitive language about driving speed through a fuzzy set theory and examines the applicability for speed evaluation. As a resul, the membership function of the recognized as medium by drivers almost agrees with the frequency distribution of speeds on roads constrtained at 50km/h.

In this study, the attitudes of about 1200elementary and secondary students towards sciences lessons and scientists were investigated. For the survey of this study, simillar numbers of students in Seoul were selected from the 5th, 8th and 11th grades and from both sexes. For the attitudes towards science lessons, in the survey questionnaire, there were questions on the type of science lesson which students prefer and on student's assessment of science lessons which they receive. For the attitudes towards scientists, there were questions on scientists whom students respect, on students assessment of scientists and on students assessment of themselves. Results of this study can be summarized as follows: (1) A great majority of students prefered the laboratory-based to classroom-based lessons, but this tendency was less apparent in olderstudents.More boys, compared with girls, prefered laboratory-based study. (2) The student's assessment of science lessons was positive in the elementary school, neutral in the middle school and negative in the high school level. Boys showed more positive attitudes towards the study of science. (3) Apparently more girls than boys mentioned Madam Curie as a scientist whom they respect, Students tended to respect scientists in terms of their personalities rather than their cognitive abilities. (4) Students tended to assess that scientist's are more able than themselves in cognitive areas while themselves are better in affective areas. The gap between student's asessments of scientists and that of themselves became bigger in high school students. The gap between boy's assessments of themselves and girl's assessments of themselves was bigger in high school level than in middle school. (5) The decline of students attitude towards science lessons was bigger than their attitude towards scientists.

Purpose : This study was conducted to examine the knowledge of, attitude toward, and education requirements for dementia that students majoring in occupational therapy have and to determine the correlations between knowledge of and attitude toward dementia according to the degree of dementia education provided in a university. Methods : From January 2021 to February 2021, 150 students majoring in occupational therapy in Daejeon, Jeollanam-do, and Gyeongsangnam-do were enrolled in this study and surveyed using a questionnaire. The students who participated understood the purpose of this study and agreed to participate. For data analysis, SPSS version 20.0 was used. Results : The subjects scored, on average, 18.64 ± 3.23 of 30 points Knowledge of dementia. The subjects had many correct answers in the items on dementia assessment, diagnosis, and treatment and care, whereas they had few correct answers in the items on the risk factors of dementia. In terms of attitude toward dementia, the subjects scored 37.38 ± 8.32 on the stability subscale and 48.26 ± 9.11 on the knowledge subscale; thus, they had higher scores on the knowledge subscale. The subjects had high educational requirements regarding the cognitive activity and activities of daily living of occupational therapy for dementia. The subjects' knowledge of dementia had a positive correlation with their attitude toward dementia according to the degree of dementia education (p<.05). Conclusion : The students majoring in occupational therapy had high educational requirements of the cognitive activity and activity of daily living for dementia. When they had more education of dementia, their attitude toward dementia had a positive correlation with their knowledge of dementia. Therefore, it is considered that students majoring in occupational therapy need to have professional education in their university curriculum.

Purpose: The purpose of this study was to examine the nurses' knowledge and attitude to pain management in children and explore the status of pain management in clinical practice. Method: The subjects were 131 nurses enrolled in 3 university affiliated hospitals. Questionnaire method was utilized for data collection. Data was analyzed by SPSS statistical program. Result: The result was as follows: 1. The overall mean score of the pain knowledge was 16.88 (58.2％). The percentages of correct response in test subsections were pain assessment 45.5, choice of medication and drug action 48.7, and pain statement 79.6 respectively. 2. 70.3％ of the nurses agreed or strongly agreed that the procedural pain should always be eliminated. And, 44.3％ of the nurses agreed or strongly agreed that post-operative treatment of pain in children should always aim at eliminating the pain completely. 3. There was a significant relationship between pain attitude and knowledge related facts about pain(r=.217, p<.01). 4. When asked to identify the point of self-reported pain on a 0-10 scale at which the nurse would give medication, point 7 was mostly identified (29％). 5. Only 19.8％ of the nurses utilized pain rating scale to assess children's pain. 6. The nonpharmacologic interventions nurses used most were position change, emotional support, and massage. 7. 68.7％ of the nurses indicated that they learned about pain management from their current working environment. Also, Mostly helpful resource identified in increasing their pain management knowledge and skills was the continuing education program. Conclusion: The findings showed that there was a need to develop educational program for adequate pain management for children. Further research study is recommended to examine the effectiveness of the intervention methods for children's pain.

The purpose of this study was to understand clinical nurses' knowledge and attitudes on pain management. The subject of the study were 254 nurses working at two hospitals affiliated with a university in Seoul. The questionnaires included four areas: general knowledge on pain, knowledge on the use of analgesia, knowledge and implementation on the pain assessment scales and pain interventions and nurses' general characteristics. The data were analyzed with descriptive statistics, analysis of variance, LSD test and t-test using SPSS statistical package. The results were as follows. 1. The mean score of the general pain knowledge was 61.46 and that of knowledge on the use of analgesia was 52.19. 2. Most nurses(74%) answered with hesitation about injecting narcotic analgesia to patients. 3. The pain assessment scale which nurses knew (57.5%) and used(48.0%) extremely was a simple descriptive scale. 4. The pain intervention which nurses knew (94.5%) and implemented(92.1%) extremely was to inject analgesia. 5. The number of nurses who had learned about pain management was 49 of 254(19.3%). 6. Nurses' knowledge on the use of analgesia was of relevance to having learned pain management, but general pain knowledge was not so relevant. According to this research, I suggest the following. 1. It is necessary to develop an education program with actual practice and intervention which nurses can perform for themselves. 2. It is necessary to continuously educate about pain management in clinical wards.

Purpose : Sexual abuse especially in younger group have been growing. This study was performed to propose the fundamental data for developing early education program to prevent damage from sexual harassment in elementary school students. Method : Questionnaire survey on cognitions and experiences about sexual harassment was done on 3125 elementary school students from seven elementary schools in Busan area from January to March, 2002. Data analysis was done with SPSS (ver 10.0). Results : Though 82% of the students have ever herd about sexual harassment previously, but self assessment of 'well-known' was only 5%. About 40% of them have ever experienced audio-visual sexual materials mainly through PC (18%), media (14%), etc. And, 60% of them have ever educated about sexual harassment. In cognitions, they agreed 'unwanted touch', 'intentional showing his (her) own body', 'send lewd mails and pictures', but disagreed 'ask massage from aged', 'gaudy joke' as one of sexual harassment. In attitudes, 'no response', 'defense with friends and family', 'express unpleasantness apparently' were desirable pattern, instead, 'his (her) own responsibility', 'problem only between person concerned', 'neglect is the best way' were undesirable. About 24% of them have ever experienced at least one of the fifteen types of sexual harassment with major types of lewd mails pictures (11%), hugging (5%), ask massage (4.7%) and unwanted touch (3.3%). The experience by gender was higher in girls (25.0%) than boys (22.4%) with no statistical significance. The mean level of cognition and attitude out of one hundred was $70.3{\pm}28.1$ and $73.5{\pm}15.9$, respectively. The mean frequency of experience was $0.4{\pm}1.1$ times. The level of cognition and attitude was higher in girls, 6th graders, and in ever educated group (p<0.001). Conclusions : The cognition level of elementary school students about sexual harassment assessed considerable. And, they also experienced several types of sexual harassment, though not too much. Therefore, compatible education program let them able to protect themselves from sexual harassment should be developed and applied even in early school age.

The UN's 17 Sustainable Development Goals (2018) were created to address environmental pollution and climate change (SDGs). The goal of this study is to find out how well-informed Vietnamese students are about the SDGs. Knowledge, attitudes, and practice (KAP) questionnaires were used to survey 1,010 students across Vietnam's universities, and the data was analyzed using SPSS software version 20. The findings suggest that both knowledge and attitude have a positive impact on the practice level. However, when comparing the correlation between the variables and the level of practice, advantage belongs to the relationship between the attitude and the level of practice (r = 0.982^**, n = 1010, p = 0.00), the correlation between knowledge and practice level is weaker (r = 0.616^**, n = 1010, p = 0.00). Statistical data also show that many Vietnamese students do not have access to information about the SDGs. The majority of the target population who have been contacted and have a basic understanding of the SDGs have done so through their academic degree. From there, it is clear that education is the most effective strategy for Vietnamese students to modify their environmental understanding and actions.

The purpose of this study is to examine the effect of cooperative making problems and solving problems for formative assessment at finish stage on science academic achievement and scientific attitude. This study is conducted in 51 sixth-graders of two classes. The experimental group was provided with a teaching-learning course based on cooperative making problem and solving problem at finish stage. And the control group was provided with general classes based on the contents in teacher's guidebooks. The experiment was performed with the second and third units of the sixth grade, for about two month and obtained the following results: First, students prefer to make supply-type items than multiple choices. And by the Bloom's revised taxonomy of educational objectives, students prefer to make the problem types of 'Factual Knowledge' and 'Conceptual Knowledge'. Also students prefer to make the problem types of 'Understanding' and 'Applying'. Second, cooperative problem making and solving problems at finish stage has same effect on academic achievement in comparison to teacher-driven activity. Third, the experimental group made statistically significant difference in self-efficiency, contrary to the general science classes. Especially, it turned out that a meaningful effect was discovered to a cooperativity, openness. Finally, it turned out that many students thought cooperative making problem and solving problem at finish stage gave the help approving their cooperativity and openness at the investigation of awareness.
