Objectives: This study aims to examine factors affecting depression of Older Adults by using the data of the elderly survey conducted by the Korea Institute of Health and Social Affairs in 2020. Methods: The total sample was 4,777 people aged over 65 years old. In this study, sociodemographic variables, information devices'use behavior and discomfort variables were input to examine the effect on depression. The data was analyzed with t²-test, ANOVA and hierarchical regression by SPSS statistic program. Results: First, use behavior and discomfort of information devices and depression were significantly different by sociodemographic variables(sex, age, level of education, marital status). Secondly, regression analysis showed that age and level of education affected an influence on depression in Model 1, which analyzed only sociodemographic variables. However, Model 2, which analyzed devices' use behavior and discomfort variables at the same time, showed that they affected depression. Conclusions: It was suggested to develop customized health education and mental health promotion were needed to reduce depression in the elderly.

This research investigates the historical changes of the educational system for the clothing departments at vocational high schools. According to the growth of the fashion industry, employment potential in the clothing departments of the vocational high schools, numerical changes in the educational statistics, and curriculums were investigated by papers, reports, and statistic data. The statistic data were derived from the 'Center Educational Statistics and Information', 'School Information' (Hak-gyo Alimi), 'Korean Statistical Information Services' and internet home pages of vocational high schools. Technical service workers that graduate from clothing departments and vocational high schools have limited competitiveness in a thriving fashion industry field. Highly developed fashion industries require more professional workers in fashion design, fashion marketing, and fashion materials. Compared to 1994, when 35 classes were conducted in 5 vocational high schools, 69 classes are now conducted at 15 schools. They have over 2,000 students and produce over 600 graduates. However, 222 credits of the $1^{st}$ curriculum in 1958 went down to 82 credits in the 2007 revised curriculum to complete the credits of clothing departments. The 15 courses of the 1st curriculum fell to 5 courses in the 2007 revised curriculum on the number of major subjects. It is a fundamental problem that major courses in clothing education have been excessively reduced despite the demand for of highly specialized workers in the fashion industry. In the view of operating conditions of those schools, there were several problems such as the wide gaps in the curriculum, limited equipment, the supply of teachers, and counseling on the choice of college or a career. In conclusion, the following measures are required: 1) the increase of complement credits in major subjects and renovation of curriculum, 2) national substantial support to change the social circumstance concerning vocational education and occupational consciousness, 3) operation of credit approving systems in universities and colleges for students that have completed the same courses at vocational high schools, 4) designing realistic programs for vocational education and cooperation systems with corporate enterprises.

The notion of outcome-based educational paradigm and its adaptability for higher education has become a recent growing and quite stirring trend. In the year 2017-18, this educational philosophy has been embraced by some of the higher educational institutions in Pakistan as well. This research attempts to investigate OBE and non-OBE systems in the context of students learning outcomes and academic attainment levels in engineering education in Pakistan. The study has been conducted on undergraduate students of MUET, Jamshoro, Sindh Pakistan. The students of the software engineering department are taken as the sample. Student cohorts are formed i.e., OBE and non-OBE (traditional/teacher-centered approach) cohorts. The summative assessments of semester exams are used for data analysis descriptive statistics and independent samples t-test is performed to set up the group statistic. The findings of this study show that, in terms of students' performance, the OBE system outperforms the traditional system and this transition in engineering institutions might be beneficial in the future.

In order to adapt to the economic change with the rapid world change, the wise consumers should have positive cognizance of their roles and are requested to fulfil their duties as a consummer. Such capability of the consumer could be acquired from home, mass media and school, and specially the role of mother at home would have a great influence on their early children's consummer activities. The purpose of this study was to investigate the interrelationship of the consumer behavior between mother and their children. As a result of this study, the mother with higher educational background could manage effectively the allowance of the children. The mother with older age had a great influence on the consumer's role of the children and high record of the execution. Employed mother had higher level of execution for the consumer's rights than their count part. Accordingly, the consumer behavior of the mother will have an influence on the children's consumer behavior. Such a result showed the meaningful statistic relations(r=3.6, p<.001) for the economy activity of the children the home management and economy life of the mother, and the purchasing activity of the children including the execution of the consumer's right. In their regard, there was the significant statistic relations(r=19, p<.05) between the children's pocket money and the housekeeping management of the mother. In the meantime, it showed that another changing factor concerned with the consumer behavior of the mother have little influence the children's allowance.

We have inquired on what the statistical classes of the secondary schools had been aiming to, say the epistermlogical objects. And we now appreciate that the main obstacle to the systematic articulation is the lack of anticipation on what the statistical concepts are. This study focuses on the ingredients of the statistical concepts. Those are to be the ground of the systematic articulation of statistic courses, especially of the one for the school kids. Thus we required that those ingredients must satisfy the followings. i) directly related to the contents of statistics ii) psychologically developing iii) mutually exclusive each other as much as possible iv) exhaustive enough to cover all statistical concepts We examined what and how statisticians had been doing and the various previous views on these. After all we suggest the following three concepts are the core of conceptual developments of statistic, say the concept of distributions, the summarizing ability and the concept of samples. By the concepts of distributions we mean the frequency views on each random categories and that is developing from the count through the probability along ages. Summarizing ability is another important resources to embed his probe with the data set. It is not only viewed as a number but also to be anticipated as one reflecting a random phenomena. Inductive generalization is one of the most hazardous thing. Statistical induction is a scientific way of challenging this and this starts from distinguishing the chance with the inevitable consequences. One's inductive logic grows up along with one's deductive arguments, nevertheless they are different. The concept of samples reflects' one's view on the sample data and the way of compounding one's logic with the data within one's hypothesis. With these three in mind we observed Korean Statistic Curriculum from K to 12. Distributional concepts are dealt with throughout but not sequenced well. The way of summarization has been introduced in the 1 st, 5th, 7th and the 10th grade as a numerical value only. One activity on the concept of sample is given at the 6th grade. And it jumps into the statistical reasoning at the selective courses of ' Mathematics I ' or of ' Probability and Statistics ' in the grades of 11-12. We want to suggest further studies on the developing stages of these three conceptual features so as to obtain a firm basis of successive statistical articulation.

This study investigates the change in two theoretical constructs, attitudes toward mathematics and mathematics self-efficacy, among college students involved in a learning community model. The case of this study was a developmental mathematics class offered at a historically black college located in the southeastern United States. Subjects included 31 students enrolled in an introductory mathematics course, some of whom participated in a learning community (treatment group). The participants completed mathematics attitudes and mathematics efficacy instruments twice: at the beginning of the semester and again at the end. Data was analyzed using descriptive statistics and a non-parametric statistic. The results showed that students' attitudes toward mathematics and mathematics self-efficacy are strongly correlated; the mathematical problem-solving efficacy changed significantly over time and it is significantly higher in the treatment group than in the control group; and the treatment group produced better outcomes. These findings indicate that a learning community model can increase students' mathematics self-efficacy beliefs. It is recommended that mathematics self-efficacy and attitudes toward mathematics be measured over an extended period of time when a learning community is implemented.

In this paper we present the simple updating formulas for a sum of product and a sum of cross product when a new value is added on or a specific value is eliminated from the original data. The sample variance and correlation for the new data set are derived by new computing formulas. Any statistic which is a function of the sum of product and a sum of cross product also can be updated by proposed method even though the original data is not available.

It is a common saying that markov-chain is a special case of probability course. That is to say, It means an unchangeable markov-chain process of the transition-probability of discontinuous time. There are two kinds of ways to show transition probability parade matrix theory. The first is the way by arrangement of a rightangled tetragon. The second part is a vertical measurement and direction sing by transition-circle. In this essay, I try to find out existence of procession for transition-probability applied markov-chain. And it is possible for me to know not only, what it is basic on a study of chain but also being applied to abnormal problems following a flow change and statistic facts expecting to use as a model of air expansion in physics.
