Laminar burning velocities have been predicted by constant volume combustion chamber, counter flow burner and others. In this study, the measured flame propagation velocities in an assembled annular stepwise diverging tube were plotted with respect to equivalence ratio, length scale, and velocity scale. Three dimensional approach to understand the flame propagation velocity including laminar burning velocity is investigated, and the surface provides the correlation among quenching distance, propagation velocity, and equivalence ratio.

The problem whether a given grammar G generates an LL language or not is investigated in respect of LL transformable grammars. The previous work involves a nondeterministic intricated parser construction for the characterization of LL transformable grammars. The method hence does not give the intuitive understanding of the essence of LL languages. This paper suggests a characterization of LL transformable grammars based on grammatical derivations instead of the complicated parser construction. The new characterization contributes to intuitive understanding of the essence of LL languages.

Purpose: The purpose of this study was to analyze life respect-related content in the 7th to 10th grade textbooks of middle and high schools. Methods: Sixty two textbooks adopted as middle and high school textbooks were analyzed for content on life respect. Results: There were 6 categories related to life respect content in the 7th to 9th grade textbooks ("prevention of accidents and the first-aid", "mental health", "sex and health", "prevention of drug abuse, smoking and drinking", "normal life and health", and "society and health"). Content on life respect in the 10th grade textbooks was categorized as "drug abuse, smoking, drinking, and health", "sex and health", "mental health", "life science and treating human life too lightly", "normal life and health", and "society and health". Conclusion: Content on life respect attached importance to more practical issue such as prevention of violence and suicide rather than fundamental understanding about self and life. These results suggest that the content on life respect should help adolescents find their own values and meaning of life within the concept of coexistence.

This paper aims to find out how did elementary students understand scientific units in science textbooks. The subjects were 191 students of the 6th grade from 7 elementary schools in 3 different areas, consisting of 70 from 4 village schools of, 64 from 2 town schools of Gyeongnam province, and 57 from one city school in Ulsan Metro City. A test was developed based on the analysis of scientific units in the science textbooks and teacher's manuals constructed according to the 6th and 7th National Science Curriculum. The understanding of elementary students' on the scientific units(Temperature, Length, Weight, Volume, Speed, Plane Angle) were surveyed. The result are as follows: Regarding the temperature unit, the students generally well understand why to measure and how to read temperature, but had some problem in recording it, in confusion with the plane angle sign. As for the length unit, they obtained high scores in understanding the purpose of measuring length as well as recording and reading it. Which indicates that they are well aware of and use the unit appropriately. With respect to the weight unit, they got high scores in reading and recording weight, which means most students have no problem using the unit. However, it was found that they do not understand why to use the plate balance scale. The volume unit was one in which the students got relatively lower scores. They do not perceive the object of using a scale cylinder and confuse it with a device of length measurement. The unit of speed is the most difficult one for children's of science to understand, presumably, because it is an derived unit from two basic units. It is also assumed that the students got the highest score in the plane angle unit because they studied the unit immediately before the test. From the children's understanding of science units above the teacher's understanding and teaching methods presumed to play a major role for children to understand and use the science units properly.

This study Research is physical in times of great social and cultural influence in adolescence. In terms of spirit, growth is accelerated, developmental and situational stress is experienced in the process of finding identity, and crisis management ability is also insufficient for emotional confusion and frustration. Therefore, it has the characteristic of falling into anxiety and depression for no reason or showing strong hostility or aggression against minor stimuli. By understanding the impulsiveness, which is an important determinant of suicide in adolescents, the seriousness of suicide is recognized through the current status and reality of suicide in adolescents, and stress, which is a risk factor for suicide.It is meaningful to analyze the effectiveness of youth suicide prevention by practicing the value of life respect through life respect education programs to reduce depression and improve self-esteem as a protective factor.

Forest Canopy Density is a dynamic process mediated by various natural and anthropogenic factors. It can be changed over time and locations in the same forest type and landscape. However, human dimensions are considered as the primary force of landscape change and subsequent forest canopy loss in tropical regions of the world. Many studies have been indicated that roads have a far greater impact on forests than simply allowing access for human use. Similarly, rivers have been used as means of transportation, hence illegal logging and felling further deplete forest canopy density. The main objective of this study was to investigate the spatio-temporal dynamic alterations of Forest Canopy Density (FCD) across with site associated factors such as biophysical, physical and human interferences in tropical region of Nepal from 1988 to 2001. Landsat TM and ETM+ of 1988 and 2001 were used to assess the spatial and temporal dynamic alterations of FCD. This analysis revealed that distance to human settlements at P=<0.01, rivers, human interferences (path and fire) and species composition had a statistically significance at P=<0.05 level. However, other factors did not show any significant relation. So, we concluded that understanding of dynamic alterations of FCD with respect to factors was quite complex phenomena. Other surrounding environment could also playa significant role. A comprehensive analysis could be required to understand such complexities. Therefore, additional factors such as climatic, biophysical, social, and institutional with respect to spatio-temporal variability should be considered for the better understanding of canopy dynamic.

Objectives : We developed the short form of the Mentalization Improvement Program for Adolescent-Community Model (MIPAdo-CM-S), based on the concept of the mentalization. Methods : The MIPAdo-CM was composed of 6 sessions and was applied to 133 students in the 1st grade of a middle school for six weeks during their regular school hours. After 6 weeks, we compared the endpoint changes of Adolescent Mental Problem Questionnaire-Revised (AMPQ-R), Emotional Empathy Test, Peer Aggression Scale, Peer Bullying Scale, School Adjustment Scale, Test Anxiety Inventory and Visual Analogue Scale between the subject and the control group. Results : On the Visual Analoge Scale, students in the trial classes reported an increased understanding and respect for others, as well as themselves. Conclusion : The efficacy of MIPAdo-CM was subjective improvement of understanding and respect for both others and themselves. To prove objective usefulness of this program, further studies should be administered in the form of long-term, regular and structured courses.

Purpose: This descriptive research study is intended to develop practical strategies for enhancing the quality of elderly care by evaluating the levels of ageism and compassion competence among clinical nurses and their impact on geriatric nursing performance. Methods: This study involved 162 nurses who provided direct care to elderly patients in a department with many such patients. Of the 161 returned questionnaires, 150 were analyzed, excluding 11 that had insincere or missing responses. To analyze the data, a comprehensive approach was employed using the IBM SPSS 27.0 program that included calculations of frequency and percentage, mean, and standard deviation, as well as more complex statistical tests such as the independent t-test, one-way ANOVA, Pearson's correlation coefficients, and hierarchical linear regression analysis. Results: Compassion competence was significantly positively correlated with elderly care and negatively correlated with ageism. This study conclusively demonstrates that compassion competence among nurses in geriatric nursing situations plays a crucial role in provision of quality nursing grounded in understanding and respect for the elderly. Consequently, it is imperative to develop educational strategies tailored to each career stage of nursing practice to further enhance effective elderly care. Conclusion: This study conclusively demonstrates that compassion competence in geriatric nursing situations plays a crucial role in provision of quality nursing grounded in understanding and respect for the elderly. Consequently, it is imperative to develop educational strategies tailored to each career stage of nursing practice to further enhance effective elderly care.

The objective of this study is to develop self-esteem program for elementary school students by accepting themselves. Elementary school students' self-esteem is closely related with accepting themselves as they are. For this reason, the contents of this study were consisted of stability, self-understanding, self-acceptance, self-respect, personal relationships. Three experts accomplished program structure and contents design performed by two tests on validity. The need-survey for this was based on the participants who were 93 elementary school students and 32 elementary school teachers. Also, this program was designed in 3 steps of observation, conversion and relation-orientation. The contents of these steps are related with this program's propriety. This program has a little weakness in behavioristic sides because it concentrated on cognitive and affective aspect for the self-esteem development of elementary school students.
