In this paper we obtain characterizations of a family of continuous probability distribution by independence property of upper record values. Also, we introduce some examples of the characterizations of distributions from these general classes of continuous distributions.

In the meantime, the government has implemented various policies for young farmers at a time when the number of people in charge of agriculture and rural areas is decreasing, but it is difficult to secure a stable agricultural workforce. This study analyzed the mediating effect of family support in the will to self-reliance and farming continuation for young farmers at a time when agricultural and rural farmers are decreasing and aging. According to the analysis, young farmers are young, highly educated, have short farming experience, and mainly livestock and gardening were high. In addition, it was found that the will of young farmers to stand on their own feet influenced the sustainability of young farmers by partially selling their family support. The main implications are the need for support or support for internal growth of young farmers and the need for continuous family support. It was also understood that young farmers should have the will to stand on their own feet in order to have continuous and satisfactory farming results.

This study aims to examine the patterns of family finance management I Jeju island. and then to suggest the desirable directions of family finance management of Jeju households. for the purposes, 157 households were surveyed with questionnaires. This study dealt with the family income forms and family finance management behavior and the relationship between the family income forms and the family finance management behavior. percentage and $X^{2}$were undertaken as statistical methods. the following results were obtained. 1. The family income forms of the households of Jeju Island showed the trend of irregularity and unbalance. And there were 5 types of family income forms. 2. In most of the households, the couple was centered o managing the family finance. 3. In many households, wife holds the responsibility for the cost of family living, and she manages it and the total income. Here we can conclude as follows. For the desirable and balanced household management, they must have some regular and continuous income sources, and try to plan and budget.

The article presents the statistical method of grouping the results of the compressive strength of concrete in continuous production. It describes the method of dividing the series of compressive strength results into batches of statistically stable strength parameters at specific time intervals, based on the standardized concept of "concrete family". The article presents the examples of calculations made for two series of concrete strength results, from which sets of decreased strength parameters were separated. When assessing the quality of concrete elements and concrete road surfaces, the principal issue is the control of the compressive strength parameters of concrete. Large quantities of concrete mix manufactured in a continuous way should be subject to continuous control. Standardized approach to assessing the concrete strength proves to be insufficient because it does not allow for the detection of subsets of the decreased strength results, which in turn makes it impossible to make adjustments to the concrete manufacturing process and to identify particular product or area on site with decreased concrete strength. In this article two independent methods of grouping the test results of concrete with statistically stable strength parameters were proposed, involving verification of statistical hypothesis based on statistical tests: Student's t-test and Mann - Whitney - U test.

Let A be a normed space, ${\mathcal{B}}(A)$ the algebra of all bounded operators on A, and V a family of strongly upper semicontinuous functions from a Hausdorff completely regular space X into ${\mathcal{B}}(A)$. In this paper, we investigate some properties of the weighted spaces CV (X, A) of all A-valued continuous functions f on X such that the mapping $x{\mapsto}v(x)(f(x))$ is bounded on X, for every $v{\in}V$, endowed with the topology generated by the seminorms ${\parallel}f{\parallel}v={\sup}\{{\parallel}v(x)(f(x)){\parallel},\;x{\in}X\}$. Our main purpose is to characterize continuous, bounded, and locally equicontinuous weighted composition operators between such spaces.

The purposes of this research were to develop a family life education program for single-parent families in rural area and to investigate the effectiveness of education through continuous tests.For these objectives, the concurrent-type program for single-parent families that emphasized communication skills, psychological strategies, and the importance of social support system was constructed. The effectiveness of the program was evaluated by pre-, post- and delayed test through 88 single parents and their children and it was analyzed by paired t-test. The results suggested that the program was effective in improving self-esteem, self-confidence and in decreasing depression. This effectiveness was more in single-father families than single-mother families. But especially in children this effectiveness was diminished as times passed. For maintaining this effectiveness in program, more frequent and continuous following education was demanded.

Family businesses play a significant role in the overall economy of all countries, and the importance and weight of family businesses are increasing in various fields. Many factors are essential for a family business to grow into a long-lived business, that is, a sustainable business, but the most important one is succession. TRUST Lab at Hanyang University studied the importance of factors influencing the succession of the family business from the standpoint of the successor. As a result, it was confirmed that mutual trust is the most crucial factor, and conflict can destroy that trust. Therefore, in this study, we research conflict as a central topic for successful succession, which is the most fundamental reason for family businesses. This study was conducted as a qualitative research case study. By setting criteria suitable for the purpose of the study, we conducted interviews with ten successors who either worked or planned to work in a family-related company. Through this study, conflict management of key players is the most important to achieve a continuous succession of family businesses.

This paper deals with the problem of estimating an arbitrary piecewise continuous function of the parameter under squared error loss in the one parameter exponential family. Using Blyth's(1951) method sufficient conditions are given for the admissibility of (possibly generalized Bayes) estimators. Also, some examples are provided for normal, binomial, and gamma distributions.

Based on the four kinds of theoretical definitions of the continuous module homomorphism between random locally convex modules, we first show that among them there are only two essentially. Further, we prove that such two are identical if the family of $L^0$-seminorms for the former random locally convex module has the countable concatenation property, meantime we also provide a counterexample which shows that it is necessary to require the countable concatenation property.

Various modified GARCH(1, 1) models have been found adequate in many applications. We are interested in their continuous time versions and limiting properties. We first define a stochastic integral that includes useful continuous time versions of modified GARCH(1, 1) processes and give sufficient conditions under which the process is exponentially ergodic and ${\beta}$-mixing. The central limit theorem for the process is also obtained.
