This study developed examination test tools for concepts of weather changes of middle school students, analyzed the hierarchy of concepts associated with weather changes by means of knowledge state analysis method, and examined the knowledge state and lesson effects of each individual learner. The hierarchy of the knowledge state of concepts of middle school students associated with weather changes followed the steps of 'humidity ${\rightarrow}$ air mass ${\rightarrow}$ cloud ${\rightarrow}$ precipitation ${\rightarrow}$ front ${\rightarrow}$ weather'. Cases were identified where the knowledge state of students that was thought to be similar to each other among the group of students who have scored almost the same points and thus were thought to have almost the same learning ability, have turned out different in the knowledge state from each other. Namely, the level of knowledge state structuralized differed, suggesting that differing prescriptions should be made according to the knowledge state of each student concerned. Analysis of the knowledge state of learners helps prepare learning prescriptions for each student and appraise prior learning. To examine effects of teaching-learning that has taken into consideration the hierarchy of knowledge state and concepts, lessons were conducted in comparison with the order in which syllabuses are presented in the textbooks, with the result that when knowledge state of learners have been taken into consideration, students made scores significantly higher (p < .05) than otherwise. This indicates that in introducing the unit of weather changes better teaching and learning can be achieved by reordering the contents of subject matters of the textbook by grasping the knowledge state of learners.

The purpose of this study is to understand immigrant women's knowledge of menstruation, attitude towards menstruation and knowledge of contraception. The study employed a descriptive survey. The participants were 120 married immigrant women in Chonnam area. Data were collected through questionnaire and interview from July to December, 2009. The participants had average score in knowledge and attitude of menstruation and knowledge for contraception. There were statistically significant differences in knowledge of menstruation according to nationality, level of satisfaction with current lifestyle, perceived health status, number of children desired, and sources of contraceptive information. There were statistically significant differences in attitude towards menstruation according to age, nationality, perceived health status, and number of children desired. There were statistically significant differences in knowledge of contraception according to level of education, nationality, and dysmenorrhea. According as the attitude toward menstruation increased, the knowledge for contraception decreased. The results of this study suggest a need for multidimensional strategy to raise knowledge of menstruation and contraception for married immigrant women.

Purpose: The purpose of this study was to investigate caregivers' knowledge, concerns, and management of children with febrile convulsions (FC). Methods: A descriptive correlation study was conducted with 133 caregivers whose children had been diagnosed with a FC. A self-administered questionnaire was used for data collection A self-administered questionnaire was used for data collection. Descriptive statistics, t-test, one-way analysis of variance and Pearson's correlation were used for data analysis. Results: The mean percent of correct answers related to knowledge was 48.5%. Many caregivers believed that FC causes brain damage and did not know that risk of subsequent epilepsy in FC is rare. Levels of concern about FC were high. Caregivers were highly concerned about further FC attacks in the night and tended to worry that Febrile children were apt to get a fever. Many caregivers used management practices which are not recommended for FC in children. There was a statistically significant negative correlation between caregivers' knowledge and concerns about FC. There was also a positive correlation between caregivers' knowledge and management of FC. Conclusion: Findings suggest that improvements are needed in caregivers' knowledge and management of FC. Caregivers' concerns related to misconception need to be addressed. Development and evaluation of educational interventions on changing caregivers' management of FC are recommended.

In order to be efficient in teaching, a teacher should understand the current learner's level through diagnostic evaluation. This study has examined the major issues arising from the noble diagnostic assessment tool based on the theory of knowledge space. The knowledge state analysis method is actualizing the theory of knowledge space for practical use. The knowledge state analysis method is very advantageous when a certain group or individual student's knowledge structure is analyzed especially for strong hierarchical subjects such as mathematics, physics, chemistry, etc. Students' knowledge state helps design an efficient teaching plan by referring their hierarchical knowledge structure. The knowledge state analysis method can be enhanced by computer due to fast data processing. In addition, each student's knowledge can be improved effectively through individualistic feedback depending on individualized knowledge structure. In this study, we have developed a diagnostic assessment test for measuring student's learning outcome which is unattainable from the conventional examination. The diagnostic assessment test was administered to middle school students and analyzed by the knowledge state analysis method. The analyzed results show that students' knowledge structure after learning found to be more structured and well-defined than the knowledge structure before the learning.
