This research focuses on the modern social phenomenon on child education which still, heavily focuses on knowledge transfer where in the past, traditional society emphasized its focal point on character education. At this, character education plans from various angles have been performed. However, the timely request for character education is becoming more desperate in demand. Therefore, the research has contemplated on Sohak, which was the foundation of character education in Korean traditional education, and recognized necessity to review its modern values as the convergence era has approached our society. Modernization of Sohak's teachings to approach modern issue of character education in our society will hold significant value because of its creative inheritance of psychological values and culture to children from the traditional society.

The rate constants of solvolysis of phenyl N-phenyl phosphoramidochloridate (PhNHPO(Cl)OPh, Target Compound-TC1) have been determined by a conductivity method. The solvolysis rate constants of TC1 are well correlated with the extended Grunwald-Winstein equation, using the $N_T$ solvent nucleophilicity scale and YCl solvent ionizing scale, and sensitivity values of $0.85{\pm}0.14$ and $0.53{\pm}0.04$ for l and m, respectively. These l and m values were similar to those obtained previously for the complex chemical substances dimethyl thiophosphorochloridate; N,N,N',N'-tetramethyldiamidophosphorochloridate; 2-phenyl-2-ketoethyl tosylate; diphenyl thiophosphinyl chloride; and 9-fluorenyl chloroformate. As with the five previously studied solvolyses, an $S_N2$ pathway is proposed for the solvolyses of TC1. For four representative solvents, the rate constants were measured at several temperatures, and activation parameters (${\Delta}H^{\neq}$ and ${\Delta}S^{\neq}$) were estimated. These activation parameters are also in line with the values expected for an $S_N2$ reaction.

We propose and experimentally demonstrate an all-optical radio frequency (RF) spectrum broadening system based on time compression. By utilizing the procedure of dispersion compensation values, the frequency domain is broadened by compressing the linear chirp optical pulse which has been multiplexed by the radio frequency. A detailed mathematical description elucidates that the time compression is a very preferred scheme for spectrum broadening. We also report experimental results to prove this method, magnification factor at 2.7, 8 and 11 have been tested with different dispersion values of fiber, the experimental results agree well with the theoretical results. The proposed system is flexible and the magnification factor is determined by the dispersion values, the proposed scheme is a linear system. In addition, the influence of key parameters, for instance optical bandwidth and the sideband suppression ratio (SSR), are discussed. Magnification factor 11 of the proposed system is demonstrated.

This Study explores and describes the present status and effects of Korean social work ethic course , reflecting increasing concerns about social worker's ethics. Using the member list of the Council of Korean Social Welfare Education, this study first examines the extent to which the ethic course is established and how the course is managed. Then, for the purpose of investigating the practical effects of the enrollment in the ethic course, using the test scores designed to measure the students' sensitivity to ethical issues, this study compared test scores between students who attended the course and those who did not. This study also compared pre-post test scores of students who attended the course. The results show that enrollment in the course contributes to significant changes in the students' ethical sensitivities, in spite of social work education system that does not very yet empathize the ethics curriculum very strongly. Further, enrollment in the ethic course is proved to be a more powerful factor to ethical sensitivity than any other demographic or education related factors. These findings suggest a stronger emphasis abd serious consideration of the course, as well as more efforts to bring up professionals and invest in research in the field of social work ethic education.

In this study, we analyzed the values of ionization and ionization constants in the chemistry textbooks developed during 1945-2009 year. The chemistry teachers compared strength of strong acids in aqueous solution by questionnaire. In the questionnaire, we searched chemistry teachers' cognitions about the discordance reason of ionization constant formulation and the values in the textbooks. The subjects were 46 chemistry teachers. As results, the teachers compared the strength of strong acids in aqueous solution based on the ionization and ionization constant values in the textbooks. They didn't notice the problem of discordance of ionization constant formulation and the values in the textbooks. Even though they recognized the problem, they could not find the solution, and thought the problem arrived by experiment error or measurement error.

This study investigates the effects of clothing consumption values and subjective age on fashion adoption. To explain the fashion adoption of elderly women, 5 dimensional consumption values were adopted as explanatory factors, and subjective age is included as a moderating factor. This study tested the relationship of variables with survey data from a convenient sample of elderly women. A total of 235 complete responses were obtained from women between 50 and 71 years of age. The results are as follows. First, factor analysis on clothing consumption values resulted in 5 dimensional structures of consumption values for the sample (epistemic, symbolic, harmonic, popular, and practical values). A factor analysis on subjective age resulted in 2 dimensions (physical and mental age). Second, epistemic, popular, harmonic (-) and symbolic values (except practical value) significantly affected fashion adoption. Third, the epistemic value was the strongest factor regardless of physical and mental age but the effects of epistemic, popular, harmonic, symbolic, and practical values changed depending on the level of the moderating factor.

The purpose of this study is to investigate intrinsic values with respect to the nature of aim from the viewpoint of Dewey. The intrinsic values have been recognized as values independent of activities or the content that preexist before embodied into activities. But from the perspective of Dewey, intrinsic values can be revealed only through the activity. Because they are inherent in the activities. Dewey suggested that the educational aim that is influenced by the traditional metaphysics should be meaningless in that it is given from outside and not related to human activities. The educational purpose that influenced by modern metaphysics and contemporary theories also can be regarded external, because the content and value of learning are assumed ahead activities. In the view of Dewey, the concepts of values are exposed through activities, so they can not exist independently. According to his own metaphysics that organism and its environment interact each other, all values c an be formed only in the course of activities. Thus, the intrinsic value of Dewey is a process per se, as the intrinsic value cannot be assumed ahead activities but can be exposed through activities. Bringing meaning to life through experience is Dewey's concept of growth as an educational aim. Education under such a purpose, would give the foundation to cultivate talent who are creative, proactive and communicate with their neighbors as a member of a democratic society.

This study focuses on the differences in family values, which is a cause of family dissolution and conflicts of marriage immigrant women. This study was conducted on 441 women in Vietnam. It was done to explore their family values. Specifically, the following were examined: the overall family values and martial status of Vietnamese women; differences in their family values by region (northern, central, southern). The survey questionnaire consists of the following content: 'family perception'; 'gender-role values'; 'elderly parent support value'. The characteristics of family values of Vietnamese women are as follows. First, the scope of family perceived by them was relatively narrow. In particular, most of them didn't perceive the parents of a spouse as a familymember. Second, in terms of gender-roles, they perceived men and women as equal and didn't have strong perception of traditional gender roles. Third, they felt strongly about supporting elderly parents. The perception of supporting elderly parents is based on equal gender roles, instead of the paternalistic approach. They preferred financial support to living with parents. There were also differences in family values by region. Also, their values seemed to be the opposite of the ones well-known by region. In addition, their values were changing amid economic growth and modernization. Residents in Can Tho in the south - known to have open-minded Southeast Asian values - had the most patrilineal, traditional values with strong perception towards supporting elderly parents. Residents in Hanoi in the north - known to have heavy influence of Confucian culture - had non-traditional values with positive attitude towards liberal sex culture, divorce, and remarriage. Residents in Da Nang, a central region, had a mixture of northern and southern characteristics in terms of family values.

The purpose of this study is to raise the importance of 'family culture and values' in the process of diagnosing and discussing the causes and measures of low fertility in Korean society. In addition, I sought to find the causes of over - fertilization and ways to cope with it in terms of educational approach to establishing family culture and values. Specifically, this study firstly reviews the causes of low fertility in Korea by examining the evaluation of low fertility policies, secondly, examines the actual conditions and changes in family culture and values related to low fertility, and third, In this paper, I examined the validity of educational intervention, the actual state of intervention, the contents of education in institutional education, the necessity and effect of education, the composition of educational content, and possible policies and arguments based on educational approach. The issue of low birth rate is a national social problem facing the Korean society in the modern age. Considering its causes and countermeasures at the same time, it is necessary to pay attention to the factors of family culture and values as well as economic factors. To further emphasize the educational approach to gender equality and family-friendly family culture and values.

The aim of the study is to explore how to approach the inherent value of nature, which is the main object of earth science education, beyond its instrumental value, which is its external usefulness. Above all, it is said to be an activity-based inherent value in the entire transfer process of the experiment, which includes psychological elements. At the core of environmental ethics is value and the utilitarian question of what is worth continuing. It is a matter of more than simply continuation. The answer is the sustainable value of the natural environment, an education that must preserve its beauty as an inherent value, that is, as a heritage value as a lover of life. Furthermore, the area of valuation must be upgraded from synchronic to diachronic ethical values, with sustainable values instead of intrinsic values. In environmental ethics, the intrinsic value that shows the beauty of knowledge itself is called bequest value. The study distinguished between a priori intrinsic value that ignores existing experience and intrinsic value that is experience-oriented and activity-oriented. In addition, the intrinsic value principle centered on activities was explored through scientific experiments in earth science education and Eratosthenes's earth size measurement experiment. The value principle according to the scientific worldview serves as the basis for value judgment. Above all, intrinsic value was being revealed through the active value experience of the experiment, in which aesthetic values were involved in the process of inferring the experiment results. As an educational implication, it should be value-education that helps us internally transfer intrinsic values rather than instrumental values, which are the basis for creating a sustainable society and nature.
