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.

이 연구에서는 1945년 교수요목기부터 2009 개정 교육과정까지 개발된 화학 교과서에서 강산의 이온화도와 이온화 상수 값이 어떻게 제시되었는지 분석하였다. 또한 설문지를 통해 화학 교사들에게 수용액에서 강산의 세기를 비교하도록 하였다. 그리고 이온화도와 이온화상수 값이 호환되지 않는 이유에 대한 교사들의 인식을 알아보았다. 연구 대상은 화학 교사 46명이었다. 연구 결과, 교사들은 교과서에 제시된 이온화 상수 값과 이온화도를 근거로 수용액에서 강산의 세기를 구분하였으며, 교과서에 제시된 이온화 상수 값이 이온화도와 서로 호환되지 않는 문제를 생각하지 못하거나, 문제로 인식하는 경우에도 그에 대한 해결을 하지 못하고 실험 오차나 측정 오차로 생각하였다.

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.

This study explores the effects of an SSI-based program focused on character and values for engineering college students. The participants were fifty-four students enrolled in the program. Data sources include the students' responses to the Likert-type questionnaire on character and values as well as qualitative data such as classroom dialogues, assignment essays and field notes. The results indicate that the program significantly contributed to the enhancement of the engineering college students' perception of character and values, especially in the sub-components, sustainable development, perspective-taking, and willingness to act. In addition, the qualitative data reveals the nuances of the students' responses in the classroom dialogue and essays related to the sub-components. Based on the results, the author compares the participants' responses to other students in previous research which reported the effects of an SSI-based program on character and values. Compared to the other students, the engineering students in this study cultivated willingness to act through the SSI-based program, without improvement in most of the emotional aspects of character and values.
