The purpose of this study was to examine Korean-Chinese parent-child relationship values through Korean proverbs on parent-child relationships. A total of 233 Korean-Chinese who reside in Yungil, China participated in this study. The participants were recruited through Korean-Chinese preschools and elementary schools. They completed a questionnaire which asked to what extent they agreed or disagreed with Korean proverbs. The items were classified into four categories: filial piety (duty), child-care and education, childrearing practices, and traditional son preference (and daughter discrimination). The results showed that, although the participants highly agreed to the meaning of the proverbs, they seldom used Korean proverbs in their daily lives. The findings concluded that the participants generally manifested a traditional value of filial piety or duty. Also, the findings showed that more fathers acclaimed the value of traditional son preference (and daughter discrimination) than mothers. Finally, the degree of familiarity with Korean culture was found to be a major factor in explaining differences in levels of agreement or disagreement to the proverbs. Since Korean-Chinese ethnic minority groups in China tend to adhere to traditional Korean values, they might encounter more challenges assimilating into the mainstream Chinese culture.

The weakening effect of water on rocks is one of the main factors inducing deformation and failure in rock engineering. To clarify this weakening effect, immersion tests and post-immersion triaxial compression tests were conducted on sandstone and mudstone. The results showed that the strength of water-immersed sandstone decreases with increasing immersion time, exhibiting an exponential relationship. Similarly, the strength of water-immersed mudstone decreases with increasing environmental humidity, also following an exponential relationship. Subsequently, a statistical damage model for water-weakened rocks was proposed, changes in elastic modulus to describe the weakening effect of water. The model effectively simulated the stress-strain relationships of water-affected sandstone and mudstone under compression. The R² values between the theoretical and experimental peak values ranged from 0.962 to 0.996, and the MAPE values fell between 3.589% and 9.166%, demonstrating the model's effectiveness and reliability. The damage process of water-saturated rocks corresponds to five stages: compaction stage - no damage, elastic stage - minor damage, crack development stage - rapid damage increase, post-peak residual stage - continuous damage increase, and sliding stage - damage completion. This study provides a foundational reference for researching the fracture characteristics of overlying strata during coal mining under complex hydrogeological conditions.

To help arrive at a more accurate diagnosis of anteroposterior apial base relationship on each individual case, it is important to compare the interpretation in the same population on a longitudinal basis. The author studied on the changes of the anteroposterior apical base relationship using serial lateral cephalometric roentgenograms of 15 boys and 27 girls aged from 6 to 13 years of Korean children. Following results were obtained 1. Norms of Korean boys and girls were established. 2. With ages, there was a gradual decrease of ANB, AXB angle, and there was a gradual increase of facial angle, A-B plane angle, APDI. 3. Wits appraisal does not change significantly with ages. 4. No significant differences were observed in the changes between male and female subjects for all absolute values between the ages of 6 years and 12 years, but significant differences were observed in ANB, AXB, A-B plane angle of the age of 13 years. No significant differences were observed in the changes between male and female subjects for all incremental values between the ages of 6 years and 13 years.

The pyridinolysis of methyl phenyl phosphinic chloride is investigated kinetically in acetonitrile at -20.0 $^{\circ}C$. The Hammett and Br${\o}$nsted plots for substituent X variations in the nucleophiles are biphasic concave downwards with a break point at X = H, and unusual positive ${\rho}_X$ (= 2.94) and negative ${\beta}_X$ (= -0.48) values are obtained for the strongly basic nucleophiles. A stepwise mechanism with a rate-limiting step change from bond breaking for the weakly basic pyridines to bond formation for the strongly basic pyridines is proposed on the basis of biphasic concave downward Hammett and Br${\o}$nsted plots. Unusual positive ${\rho}_X$ and negative ${\beta}_X$ values are rationalized by the isokinetic relationship. The pyridinolyses and anilinolyses of four $R_1R_2$P(=O)Cl-type substrates, dimethyl, diethyl, methyl phenyl, and diphenyl phosphinic chlorides in acetonitrile are compared to obtain systematic information on phosphoryl transfer reaction mechanism. The combination of the two ligands, Me and Ph, shows unexpected kinetic results for both the anilinolysis and pyridinolysis: greatest magnitude of $k_H/k_D$ (= 2.10) involving deuterated anilines $[XC_6H_4NH_2(D_2)]$ for the anilinolysis, and exceptionally fast rate and biphasic concave downward free energy correlation for the pyridinolysis.

The genetic diversity of domestic quail and two wild quail species, Japanese （Coturnix coturnix）and Common quail (Coturnix japonica), found in China was studied using microsatellite DNA markers. According to a comparison of the corresponding genetic indices in the three quail populations, such as Polymorphism Information Content (PIC), Mean Heterozygosity ($\bar{H}$) and Fixation Index, wild Common quail possessed rich genetic diversity with 4.67 alleles per site. Its values for PIC and $\bar{H}$ were the highest, 0.5732 and 0.6621, respectively. Domestic quail had the lowest values, 0.5467 and 0.5933, respectively. Wild Japanese quail had little difference in genetic diversity from domestic quail. In addition, from analyses of the fuzzy cluster based on standard genetic distance, the similarity relationship matrix coefficient between wild Japanese quail and domestic quail was 0.937, and that between wild Common quail and domestic quail was 0.783. All of these results showed that the wild Japanese quail were closer to the domestic quail for phylogenetic relationship than wild Common quail. These results at the molecular level provide useful data about quail's genetic background and further supported the hypothesis that the domestic quail originated from the wild Japanese quail.

The main objectives of this study were to empirically examine the relationship between the preference of fashion styles of male college students and their individual taste in other areas including music styles and recreation types. Life style and values were also examined for their relationship with the fashion style preferences. Survey questionnaires were distributed to male college students in Seoul, Incheon and Gyeonggi-do during May and June of 2011, and a total of 256 responses were used in the final analysis. The results showed that there were three segments according to the fashion styles - 'modern-dandy', 'resistance style', 'no-individuality' groups - and there were significant differences between groups in terms of their preferred music styles and choice of recreational activities. Modern-dandy group preferred R&B, dance music and ballad, while resistance style group preferred hiphop, dance and reggae music. No-individuality group did not show any preference for a particular type of music. Both modern-dandy and resistance style groups liked sports, while resistance style group showed the lowest preference for hobby and culture. There were also significant differences in lifestyles and values according to the fashion styles of the three groups.

The choice of attenuation relationships is one of the most important parts of seismic hazard analysis as using a different attenuation relationship will cause significant differences in the final result, particularly in near distances. This problem is responsible for huge sensibilities of attenuation relationships which are used in seismic hazard analysis. For achieving this goal, attenuation relationships require a good compatibility with the target region. Many researchers have put substantial efforts in their studies of strong ground motion predictions, and each of them had an influence on the progress of attenuation relationships. In this study, two attenuation relationships are presented using seismic data of Mazandaran province in the north of Iran by Genetic Expression Programming (GEP) algorithm. Two site classifications of soil and rock were considered regarding the shear wave velocity of top 30 meters of site. The quantity of primary data was 93 records; 63 of them were recorded on rock and 30 of them recorded on soil. Due to the shortage of records, a regression technique had been used for increasing them. Through using this technique, 693 data had been created; 178 data for soil and 515 data for rock conditions. The Results of this study show the observed PGA values in the region have high correlation coefficients with the predicted values and can be used in seismic hazard analysis studies in the region.

The purpose of this study was to decipher the BRQ (Brand Relationship Quality) Construct of fashion product consumers and to identify influencing variables. Consumption values of consumers, fashion product attributes and marketing communication instruments were investigated as affecting variables. A questionnaire was distributed to 350 women between the age of 20 and 50 living in Seoul and other metropolitan areas from Mar. 5 to Mar. 18, 2008. Collected data were analyzed by factor analysis, reliability, multiple regression, frequency and percentage using SPSS (Version 15,0) statistical Package. The results were as follows: Firstly, the BRQ Construct of fashion product consumers was proved to be composed of five factors; 'self-connective love', 'pursuing symbol', 'trust', 'intimacy', and 'knowledge'. Secondly, consumption values had a significant effect on the BRQ Construct and their explanatory power was 32%, 'Epistemic value' was the most significant variable affecting BRQ. 'Functional value' had a significant influence on some BRQ factors. Thirdly, explanatory power of fashion product attributes affecting BRQ was 45%. 'Aesthetic attribute' had significant effect on all BRQ factors, while 'functional attribute' showed significant effect on only 'pursuing symbol', 'trust', and 'intimacy'. Finally, marketing communication mixes showed 21% explanatory power and 'word of mouth' and 'display' among marketing communication mixes were found as the most influential variables affecting the BRQ Construct.

Objectives : This study was performed to investigate the relationship between Sasang Constitution and length of chest and abdomen region. Methods : Forty eight participants were enrolled. Weight, height, and lengths from CV22 to CV16, from CV16 to CV8, and from CV8 to CV2 were measured. Ratios of last three lengths to total CV22 to CV2 were calculated respectively. On the other hand, Sasang Constitution was analyzed with QSCCII(Questionnaire of Sasang Constitutional Classification II). The analysis of relationship between the measurements and Sasang Constitution was carried out with SPSS to compare the mean values according to Sasang Constitution. Results : All the mean values were not significantly different depending on the Sasang Constitution, except the ratio of the length from CV16 to CV8 to the length from CV22 to CV2, only in female participants. The ratio was higher in the female Soeumin participants than any other constitutional groups. Conclusions : This result showed that Soeumin could be assumed that they might have weak digestion abilities.
