The lumbar disc is one of the first parts of the human body to age. Female discs start to age at twenty and completely age between fifty and sixty. The number of lumbar herniated intervertebral disc patients is increasing rapidly; however, studies on protective inner wear are insufficient. This study develops protective inner wear equipment for bodies. The following were the study methods and procedures. First, the protective design, pattern and making of the inner wear were based on the analysis of collected data. Second, one subject was selected, then human body parts were measured to create the inner protective pattern. The inner pattern was made by the basic size of the subject. The inner protective equipment was made for lumbar disc disease patients after a wearing test and after correcting the pattern. Third, inner protective equipment was thoroughly tested to verify the compatibility of lumbar pads. The following were the study results and observations. First, lumbar pads who had inner protection were easily worn and the design was very ladyish in contrast to other lumbar pads on the market. Second, the pattern was completed by referring to, Lee Hyoung Sook's, torso and her lumbar pad shape. The fabric was mesh (for good ventilation) and poly spandex (for elasticity). Third, lumbar inner protective equipment was verified through a subject assessment and a major assessment. This study showed high scores on appearance and functional satisfaction versus existing disc lumbar pads in the market. This study predicts that new waist protective inner wear can help the female patient's health and social life because it has great functionality and can maintain outer line patterns.

The purpose of this study was to provide the basic data needed to plan the effective teaching design of scaling education and to measure the changes in students' confidence in performing scaling according to the number of scaling practices. Scaling education is presented as a core basic hygiene competency of dental hygienists and evaluated as the practical competency of dental hygienists. This study selected 48 third-year students from the department of dental hygiene at S University in Asan, and analyzed data from completed participant surveys. The degree of "confidence in facing the subject in clinical practice," "confidence in applying hand instrument to the subject," and "confidence in applying ultrasonic instruments to the subject" was assessed on a five-point Likert scale. The difference in confidence was analyzed during five practice sessions. Each response was compared using frequency analysis, chi-square test, and repeated measurement ANOVA. Students who complained of a lack of confidence in the 14.6%, 25.0%, and 12.5%, respectively, in face-to-face practice, hand instruments, and ultrasonic instrument application responses. The more the practice was repeated, the more confident students were in all three categories, and the more statistically significant (p<0.001). As the number of scaling practice sessions increased, students' confidence in performing scaling also improved. In particular, the level of self-confidence was higher after the third practice session when compared to the first session. Therefore, it is necessary to design effective courses for teaching scaling practices so that at least three repetitive practice periods can be provided in clinical dental hygiene practices.

The purpose of this study is to draw implications through a case study on the curriculum operation of a professor who operated a programming subject as a PBL(project-based learning) method in an untact situation due to COVID-19. A survey was conducted for first-year freshmen students to determine their learning condition before project implementation. Based on the results of the questionnaire, individual interviews were conducted to identify the needs for education, and then, basic grammar for project completion and lectures that segmenting each stage of the project were composed. Repeated learning was induced through weekly quizzes, and feedback was given by giving time in advance until the project deadline. 23 students (40 students in total) completed the project. The remaining 17 students took the exam but did not complete the project. The purpose of this study is significant in that it investigated whether a project can be carried out through instructional design, execution, and interaction while operating a programming subject through PBL in the COVID-19 environment.

The purpose of this study is to propose an improvement plan based on an analysis of the current earth science teacher education curriculum in the department of education in the four fields of teaching profession theory: student-teacher practice, subject lesson education, and subject content education. The following are the conclusions and suggestions of this study. In case of teaching profession theory, too much emphasis is put on pedagogical theory over practical issues, and a problem arises upon completion. Therefore, it is sugguest that teaching profession theory might be completed before subject lesson education to ensure more authentic subjects performing teaching profession. The current term for student-teacher training is too short to understand the whole school system. Current school system does not have any off-job training course or internship system. Therefore, student-teacher training term should be increased by at least $3{\sim}6$ months to play a vital role in the current system. The credit number of subject lesson education is too small compared with subject content education. Consequently, the credit number of subject lesson education should be increased, and more professor majored in subject lesson education should be recruited. Significant deviation between the content of subject content education and that of middle school grade exists, and there is also much difference in the ratio of subject according to university. To get rid of these problems, subject content education should be connected with subject lesson education and appropriate number of credit needs to be assigned to each subject domain.

The purpose of this study was to investigate the relationships between mothers involvement of their childrens peer interaction, their memory of childhood peer relations, and their perception of childrens social competence. Subject consisted of 302 mothers of 4- to 6-year-old children. A sample of mothers completed a series of questionnaires assessing their peer experiences, perceptions about their childrens sociability, and a behavioral checklist of their involvement activities. The results indicated that mothers own sociability and their perceptions of their childrens sociability influenced their involvement. More intense maternal involvement occurred when mothers perceived their children to be sociable. Mothers with sociable peer recollections appeared to take more active role in their childrens social development.

The purpose of this study was to examine the specific nature of early relationship between infant and father. The subject pool for the study consisted of 42 middle-class infant-father days. Infant's ages were 12 moths to 17 months. All were fullterm babies In order to assess the patterns of infant-father attachment each dyad was videotaped in the simulated Strange Situation of Ainsworth et al(1978). In order to assess the paternal sensiti-vity toward the infant's cue,. each dyad was also filmed for a 3-minute Questionnaire Situation Gratification of the Transition to Fatherhood. Also at home mothers completed a report on infant temperament using the Infant Characteristics Questionnaire. Among 42 infants 48% or 20 were classified as securely attached 38% or 16 as anxious-avoi-dant and 14% or 6 as anxious-resistant Using the discriminant function coefficients for combi-ning the paternal sensitivity scores 83% of the infants were correctly classified as A. B. C The patterns of attachment were not found to be significantly different in the paternal childhood experience for attachment relationship to his own parents. Degree of Difficulty and Gratification groups with respect to infant temperamental fussiness.

The purpose of this study is to reveal the meaning of ramp of Le Corbusier's Carpenter Center for the Visual Arts focused on experience of architectural promenade. The Carpenter Center was completed in 1964, only a year earlier than the death of Le Corbusier and also, this building is the only building actually constructed in North America. Despite these important facts, the meanings of the ideas of this building have not been paid attention as much as other buildings constructed at the same period, such as, Venice Hospital and Un Pavillion D'exposition in Zurich. In his book, 'Oeuvre Complete 1957-1965', Le Corbusier mentioned Carpenter Center as an architectural experiments of his ideas. The study of carpenter center will be an important architectural subject to clarify the meaning of his later works and ideas.

We consider a project time-cost tradeoff problem with two milestones, where one of the jobs has an uncertain processing time. Unless each milestone is completed on time, some penalty cost may be imposed. However, the penalty costs can be avoided by compressing the processing times of some jobs, which requires additional resources or costs. The objective is to minimize the expected total costs subject to the constraint on the expected project completion time. We show that the problem can be solved in polynomial time if the precedence graph of a project is a chain.

In this study of mathematics anxiety, mathematical learning style, and grade in school, 1,264 elementary students completed the Mathematics Anxiety Scale(Lee, 2005) and the Mathematical Learning Style Scale(Yang & Whang, 2005) for elementary school students. Analysis of their responses showed that anxiety about mathematics increased with grade in school. Among sub-factors of mathematics anxiety, the subject itself, learners' attitude, and learning environment increased the anxiety of upper grade students. Motivation, initiative, and regulation styles of learning mathematics were found to be important factors in the mathematics anxiety of elementary school students.
