Design of experiments (DoE) concept was successfully applied to determine the optimum processing conditions that yield maximum % exhaustion for berberine interaction with synthetic tanning agent pretreated polyamide substrates. The potential of synthetic tanning agent to provide anionic sites on the polyamide for berberine interaction which is cationic in nature was tested to increase the % exhaustion of berberine in this article. Experiments were designed according to Central Composite Rotatable Design (CCRD). The three factors for synthetic tanning agent pretreatment and two factors for berberine interaction each at five different levels, including central and axial points were considered. Experiments were conducted in a laboratory scale infra-red treatment instrument according to CCRD. For each response, second order polynomial models were developed using multiple linear regression analysis incorporating linear, interactions and squared effects of all variables and then optimized. The significance of the mathematical model developed was ascertained using Excel regression (solver) analysis module. Analysis of variance (ANOVA) was performed to check the adequacy and accuracy of the fitted models. The response surfaces and contour maps showing the interaction of process variables were constructed. Applying Monte Carlo simulation, response surface and contour plots, optimum operating conditions were found and at this optimum point, % exhaustion of 81% and 74% respectively for synthetic tanning agent pretreatment and berberine interaction were observed and subsequently the results were experimentally investigated.
1. Objectives : The purpose of this study was to validate the Sasang Personality Questionnaire (SPQ) with Positive And Negative Affection Schedule(PANAS) for emotionality and Body Mass Index (BMI) for body constituents. 2. Methods : The SPQ along with Questionnaire for Sasang Constitution Classification (QSCC) II, PANAS, BMI was measured with 232 College students. The correlation coefficient was measured with Pearson correlation between SPQ and PANAS, BMI. The SPQ, PANAS, and BMI score of each Sasang constitution groups based on QSCCII were compared using analysis of variance and profile analysis. 3. Results : The SPQ score of each Sasang constitution groups was significantly (p<0.01) different. The SPQ showed significant correlation with PANAS Positive Affect (r=0.201, p=0.002), but not with the BMI (r=0.097, p=0.146). The SPQ-Emotionality scale, unlike other SPQ subscales, showed positive correlation with PANAS Negative Affection. 4. Conclusions : We performed the constructive validity of SPQ using PANAS and BMI. The SPQ would be useful for the study on psychophysiological mechanism of the Sasang constitutions.

A single recessive gene, rxp, controls the bacterial leaf pustule (BLP) resistance in soybean and in our previous article, it has been mapped on linkage group (LG) D2 of molecular genetic map of soybean. A total of 130 recombinant inbred lines (RILs) from a cross between BLP-resistant SS2-2 and BLP-susceptible Jangyeobkong were used to identify molecular markers linked to rxp. Fifteen simple sequence repeat (SSR) markers on LG D2 were screened to construct a genetic map of rxp locus. Only four SSR markers, Satt135, Satt372, Satt448, and Satt486, showed parental polymorphisms. Using these markers, genetic scaffold map was constructed covering 26.2cM. Based on the single analysis of variance, Satt372 among these four SSR markers was the most significantly associated with the resistance to BLP. To develop new amplified fragment length polymorphism (AFLP) marker linked to the resistance gene, bulked segregant analysis (BSA) was employed. Resistance and susceptible bulks were made by pooling equal amount of genomic DNAs from ten of each in the segregating population. A total of 192 primer combinations were used to identify specific bands to the resistance, selecting three putative AFLP markers. These AFLP markers produced the fragment present in SS2-2 and the resistant bulk, and not in Jangyeobkong and the susceptible bulk. Linkage analysis revealed that McctEact97 $(P=0.0004,\;R^2=14.67\%)$ was more significant than Satt372, previously reported as the most closely linked marker.
Objectives: The study purpose was to test the validity and reliability of the core emotional assessment questionnaire based on the seven emotions. Methods: Survey data were from 651 individuals and contained 141 items determined from a previous pilot study. Among the participants, 241 were retested. First, following analysis of the internal consistency reliability of the 141 items, we deleted items with Cronbach-$\alpha$ coefficient below 0.5. We then selected 100 final items after the first factor analysis. Second, the final 100 items were evaluated by internal consistency reliability, test-retest reliability, factor analysis, and correlational analysis. Results: Cronbach-$\alpha$ coefficient for the final 100 items were 0.866~0.956 and the test-retest reliability were above 0.70. The 100 items categorized into 7 factors explained 53.8% of the total variance. Analyzing the correlation of each chiljeong, we had a high positive correlation above 0.70 between sa and bi, bi and u, gong and kyeong. Conclusions: The final 100 items used for the core emotional assessment questionnaire based on the seven emotions showed satisfactory reliability and validity. Thus, it may be an appropriate instrument for measuring Chiljeong in the general population.

This study reviewed different results according to the selection of viewpoints and considerations of the neighborhood in the analysis of view to regulate the height of buildings. To do this, 4 cases were set according to the analytical methodology and a GIS simulation was performed. Characteristics of each methodology were compared and analyzed by simulated values with ANOVA(analysis of variance) and post-hoc analysis. First, the method using moving viewpoints was found to be appropriate for the regulation of building height as it could reflect basic characteristics of landscape which was sequential and it did not show big difference in analysis result according to situational setting. Second, the method using grid viewpoints showed a problem that viewpoints at left and right sides viewed ridges of other mountains than the background mountains of the target land. Additionally, the simulation method that induces three-dimensional cross-sections between multiple sight-surface and virtual construction points created at viewpoints used in this study was found to be useful in the simulation review with various settings as it induced the marginal height of the spot quantitatively.
This study investigates the effect of consumer culture and awareness of wedding ceremonies between parents and children as well as preference for a simple wedding in order to develop a simple wedding concept. The data for statistical analysis came from 375 of children 216 and parents 159. Data was analyzed with t -test, analysis of variance, exploratory factor analysis, Cronbach's $\alpha$ and regression analysis by SPSS ver. 18.0. The results were summarized as follows. First, children had a higher symbolic consumption than parents and parents had a higher functional consumption than children. Second, children prefer a discriminate and characteristic small wedding, while parents prefer an economical, meaningful and nonconforming simple wedding. The variables that effect parents simple wedding preferences were consumer culture, awareness of wedding ceremony, gender, and education; those of children were, consumer culture, awareness on wedding ceremony, gender, and age. Children had a functional and economical consumption focused on meaningfulness and rationale of the wedding, they prefer an economical meaningful small wedding. Children had functional consumption that prefers a discriminate characteristic small wedding and a nonconforming small wedding compared to men. Parents did not have symbolic consumption and focused on the meaningfulness and rationale of the wedding, they prefer an economical meaningful small wedding. Parents focused on the meaningfulness and rationale of the wedding; in addition women prefer a discriminate characteristic small wedding compared to men. Parents had functional consumption and focused on the meaningfulness and rationale of the wedding with a preference for a nonconforming small wedding.

This study analyzed the gap in perception between communication with parents and filial piety according to the general characteristics of teenagers. The test subjects were high school students from academic and vocational school from different districts of Seoul. A survey was conducted from March to July of 2014 to 290 high school students. Data analysis was conducted on the SPSSWIN 18.0 program using a t-test, one-way analysis of variance, correlation analysis, and other tests. The empirical analysis of the experiments were verified at the significance level of 5%. First, communication with fathers differed significantly depending on the school division, economic class, religion; and communication with mothers differed significantly depending on school division, grade-level, academic performance, domestic discipline, and economic class. Second, the perception of filial piety showed a significant positive correlation with the communication with the mother; and with the communication with the father. The implication of this study is that better communication between the parents and teenagers correlate with the higher filial piety according to the general characteristics of teenagers, and should become a central material for policy.
Background: The gluteus medius (Gmed) plays a critical role in maintaining frontal plane stability of the pelvis during functional activities, such as one-leg lifting. Side-lying hip abduction (SHA) has been used as a dynamic test to evaluate Gmed function. However, the abduction force of the lower leg against the floor is not controlled during SHA. Therefore, hip abduction performance with contralateral adduction in the side-lying position (HAPCA) can be proposed as an alternative method to assess performance of hip abduction. If the number of HAPCA is related to the lateral pelvic shift distance, a new quantitative measurement for hip abductor function may be presented. Objects: This study aimed to investigate the relationship between the number of successful HAPCA and the lateral pelvic shift distance during one-leg lifting. Methods: Thirty healthy participants were recruited, and lateral pelvic shift distance was measured during one-leg lifting test using two-dimensional analysis. The number of successful HAPCA was counted when participants touched both target bars at the beat of a metronome. Results: There was a negative correlation between the number of HAPCA and lateral pelvic shift distance during one-leg lifting (r = -0.630, p < 0.05). The number of HAPCA accounted for 39.7% of the variance in the lateral pelvic shift distance during one-leg lifting (F = 18.454, p < 0.001). Conclusion: The number of successful HAPCA is significantly correlated with lateral pelvic shift distance during one-leg lifting. This finding suggests that HAPCA can be proposed as a new measurement for hip abductor performance and more research is needed on its relationship with hip abductor strength.
Background: This study aims to analyze the cost and the length of stay (LOS) of acute myocardial infarction (AMI) patients with coronary artery stenting according to the characteristics of individuals and institutions. Methods: The data was collected from Korean National Health Insurance Service's customized database in 2010 and 2015. Chi-square test, t-test, analysis of variance, and multilevel analysis were performed. Results: The intraclass correlation coefficients for cost were 7.02% in 2010, 5.61% in 2015 and for LOS were 3.17%, 1.40%, respectively. The average costs were 9,067,000 won in 2010 and 9,889,000 won in 2015 (p<0.0001). However, the cost in 2015 was lower than the cost applying increased fee. The costs increased in aged 50-59 years, 60-69 years, and aged ≥70 years versus in aged under 49 years. The cost was higher in Charlson comorbidity index (CCI) 3 to 4 and ≥5 than in CCI 0. The costs were lower in male, medical aid recipients, metropolises, and local hospitals in other regions in 2010. LOS decreased from 8.1 days in 2010 to 7.4 days in 2015. It decreased in male, high income group, and the group of admission via emergency room. However, it increased in higher ages and medical aid recipients, and it also increased when CCI rose. The Internal Herfindahl Index was related to LOS in 2010. Conclusion: The variation of hospital level was small compared to the patient level. Therefore, it is important to implement applicable policies at the patient level in order to reduce cost and LOS of AMI patients.
Background: The purpose of this study is to investigate the effects of entrance exam stress on oral health behaviors and subjective oral health status in female high school students. Methods: A self-reported questionnaire was administered to 216 female high school students in the Gwangju area. We performed an independent t-test, one-way analysis of variance (ANOVA), Pearson's correlation coefficient, and multiple regression analysis using the SPSS/WIN 21.0 program. Results: The average of the entrance exam stress was 2.73, and among the sub-areas, the tension for exam/poor stress was the highest with 3.21. As a result of analysis of general characteristics and subjective oral health status, oral mucosal disease was lower in family income level (p<0.05), bad breath was significantly higher with lower academic performance (p<0.001) and family income level (p<0.05). As a result of oral health behavior and subjective oral health status analysis, dental caries has more than 4 times of caries snacks (per week) (p<0.05), bad breath was found to be more perceived when the average number of daily brushing was 2 or less (p<0.01). Factors affecting subjective oral health status were that dental caries was a patients pressure stress (β=0.202); temporomandibular disorder (β=0.227), xerostomia (β=0.342), and oral mucosal disease (β=0.190) were insufficient spare time; bad breath was academic performance (lower) (β=0.231) and insufficient spare time (β=0.184). There was a statistically significant positive correlation between the subjective oral health status and the subarea of entrance exam stress, excluding future uncertainty stress. Conclusion: It is considered that oral health education should be conducted to prevent oral diseases for students with high parental pressure and insufficient spare time stress as well as finding practical ways to reduce entrance stress.
