This study performed intensive indicators based on a model of economics of education. Trends of childcare in Korea were obtained by producing values developed with statistical data. Results showed that such simple initial indicator values as numbers of children, institutions and teachers have improved. However, intensive indicator values that take demographic and economic conditions into consideration have not reached the same rate of progress as the initial indicator values. In other words, qualitative growth remains at an unsatisfactory level in comparison to quantitative growth and to qualitative growth in members of the Organization for Economics Cooperation and Development (OECD).Thus, financial investment by the government should be expanded in order to reach the desired level of high quality in daycare for children.

This study was to identify the factors of ethical values in nursing students. The survey was conducted in two nursing colleges (n=180) using self-reported questionnaire. The data were analyzed with descriptive statistics, t-tests, ANOVA, Pearson's correlation coefficient and multiple regression analyses using SPSS/WIN 21 software. Influencing factors of ethical values were empathy(t=3.436, p=.001), teaching method except lecture(t=3.037, p=.003), and curriculum track at high school(t=2.309, p=.022). The model was statistically significant explaining 16.2% of the variance (F=11.185, p<.001). This study suggests that strategies for increasing nursing students' ethical values include reinforcing empathy, utilizing various type of teaching method except lecture in nursing ethics class, and allowing high school students applying to college of nursing regardless of their curriculum track.

The purpose of this study is to investigate the value perception changes of early adolescents, who are from 5th grades to 7th grades regarding to agriculture and rural communities through debate education. Since current education policy to educate agricultural value is limited in solving stereotypes and acquiring abundant relevant knowledge about agricultural values, this study tried to test the effect of debate education for the change of value perception of early adolescents about agriculture and rural communities. Through the two weeks of a debate education course, the differences of perception changes between the experimental group and control group were analyzed. As a result, education on agriculture and rural communities through debate has a great influence on the change of value perception and thus, it could be used as a supplementary educational method for literacy education and field trip learning. Lastly, limitations and implications for the study is discussed.

Magnetic relaxation properties of pure MgB₂ powder samples and diluted water-treated MgB₂ powder samples were investigated. The magnetic field H-dependence, m(H), and the time t-dependence, m(t), of the magnetic moment m were measured and analyzed using the PPMS-VSM magnetometer equipment, respectively. The m(t) reduction rates of pure MgB₂ powder samples and diluted water-treated MgB₂ powder samples decreased to about 0.7 ~ 1.8% and 0.6 ~ 1.0% for about 7200 s, respectively, at temperature T = 15 K. The magnetic relaxation properties of the two types of MgB₂ powders were analyzed by calculating the magnetic relaxation rate S = -dln(M_irr)/dln(t) values according to Anderson-Kim theory. The magnetic relaxation ratio S values of the two types of MgB₂ powder samples were almost similar. As a result of the quantum creep effect, the constant magnetic relaxation rate S characteristic was confirmed at a temperature range of T = 10 K or less.

As for the practical purpose of mathematics education, the extrinsic purpose is emphasized. As an alternative to this, a discussion on mathematics education as a character education is urgently requested. It can be said that the main purpose of learning mathematics is to have a form of life that values the form and structure of mathematics. The epistemological basis of such an idea can be seen as based on Kant's philosophy. Kant's epistemology can provide one answer to the question of the intrinsic purpose of mathematics education.

Most of current watermarking algorithms for GIS vector data embed copyright information by means of modifying the coordinate values, which will do harm to its quality and accuracy. To preserve the fidelity of vector line data and protect its copyright at the same time, a lossless watermarking algorithm is proposed based on storage feature in this paper. Firstly, the superiority of embedding watermark based on storage feature is demonstrated theoretically and technically. Then, the basic concepts and operations on storage feature have been defined including length and angle of the polyline feature. In the process of embedding watermark, the watermark information is embedded into directions of polyline feature by the quantitative mechanism, while the positions of embedding watermark are determined by the feature length. Hence, the watermark can be extracted by the same geometric features without original data or watermark. Finally, experiments have been conducted to show that coordinate values remain unchanged after embedding watermark. Moreover, experimental results are presented to illustrate the effectiveness of the method.

Solvolyses with the reaction center being the sulfur of 4-(chlorosulfonyl)biphenyl ($C_6H_5C_6H_4SO_2Cl$, 1) was studied under solvolytic conditions and the extended Grunwald-Winstein equation was applied. The thirty five kinds of solvents gave a reasonable extended Grunwald-Winstein plot with a correlation coefficient (R) of 0.940. The sensitivity values (l = 0.60 and m = 0.47) of 1 were smaller than those obtained for benzenesulfonyl chloride ($C_6H_5SO_2Cl$, 2; l = 1.10 and m = 0.61) proposed to undergo dissociative $S_N2$ mechanism. These l and m values for the solvolyses of 1 can be considered to support a $S_N2$ pathway with some ionization reaction. The activation parameters, ${\Delta}H^{\neq}$ and ${\Delta}S^{\neq}$, were determined and they are also in line with values expected for a bimolecular reaction. The kinetic solvent isotope effect (KSIE) of 1.26 is also in accord with a bimolecular mechanism, probably assisted by general-base catalysis.

The present study was conducted to investigate the effect of nutrition education program on anthropometric values and boichemical index in obese children who live in Gumi city. The subjects were 16 obese boys, 20 obese girls with obesity index over 130 and 36 of their parents. The nutrition education was carried out by the professional personnel such as doctors, professors, and dietitians. The children were provided with well-balanced lunch meals and had 40min-lectures on the reasonable weight management, 40 min-games and also had regular exercises (stretching, swimming) for 90 mins everyday during 2weeks of the program. The parents had 90 min-lectures on childhood obesity, diet therapy, behavior modification, and exercise for 6times. After the program, obesity index, BMI, % body fat were significantly decreased (p < 0.05) in boys and obese index, BMI, % body fat and WHR were significantly decreased (p < 0.05) in girls. Blood cholesterol and TG levels of girls were significantly decreased (p < 0.05). These findings show that the well-designed nutrition education program for obese children can be an effective approach to help them to improve their anthropometric values and biochemical index.

The solvolysis rate constants of allyl chloroformate ($CH_2=CHCH_2OCOCl$, 3) in 30 different solvents are well correlated with the extended Grunwald-Winstein equation, using the $N_T$ solvent nucleophilicity scale and $Y_{Cl}$ solvent ionizing scale, with the sensitivity values of $0.93{\pm}0.05$ and $0.41{\pm}0.02$ for l and m, respectively. These l and m values can be considered to support a $S_N2$ reaction pathway. The activation enthalpies (${\Delta}H^{\neq}$) were 12.5 to 13.4 $kcal{\cdot}mol^{-1}$ and the activation entropies (${\Delta}S^{\neq}$) were -34.4 to -37.3 $cal{\cdot}mol^{-1}{\cdot}K^{-1}$, which is also consistent with the proposed bimolecular reaction mechanism. The solvent kinetic isotope effect (SKIE, $k_{MeOH}/k_{MeOD}$) of 2.16 was also in accord with the $S_N2$ mechanism. The values of product selectivity (S) for the solvolyses of 3 in alcohol/water mixtures was 1.3 to 3.9, which is also consistent with the proposed bimolecular reaction mechanism.
