This study investigated the relationships among cognitive age, sociocultural attitudes towards appearance, and appearance management behaviors. This study gave a questionnaire survey to adults between the ages of 17 and 76 who lived in the Daegu and Gyeongbuk regions of South Korea. Data collected from the 296 respondents were analyzed using descriptive statistics, correlation analyses, and ANOVA. The sociocultural attitudes towards appearance (awareness and internalization) were significantly correlated with appearance management behaviors (weight training, skin care, hair care, make-up, and clothing selection). The cognitive age was significantly correlated with the sociocultural attitudes towards appearance and appearance management behaviors such as weight training and clothing selection.

The present study compared mother-child relationships and sociability of only children with that of children with siblings. The mother of 105 only children and 179 children with siblings responded to questionnaires on maternal attitudes and children's sociability. The children were all enrolled in kindergartens in Seoul. The data analysis was with t-test and Pearson's correlation. The mothers of only children reported that they were more overprotective and obedient to the children than mothers of children with siblings. Only children were less autonomous in sociability than children with siblings. 'Protective' and 'obedient' attitudes of mothers of only children were positively correlated with the 'egocentrism' of the child and negatively correlated with 'autonomy' of the child.

Association rule mining searches for interesting relationships among Items in a given database. Association rules are frequently used by retail stores to assist in marketing, advertising, floor placement, and inventory control. There are three primary quality measures for association rule support and confidence and lift. If there is many item in the association rule, much time is required. Xiong(2004) studies new method which is to compute the support of upper. They used support of upper to the $\theta$. But $\theta$ is subjective. In this paper, we present statistical objective criterion for efficiently identifying correlated pairs.

The purposes of this study were to uncover the relationships and correlations between mental health, resilience and happiness. The sample consisted of 184 intermarried Korean men. The data were analyzed by means of frequency, Pearson's correlation, and multiple regression analysis using SPSS. The major findings were as follows; Mental health was negatively correlated with resilience and happiness, except for the component of negative emotion. Additionally, resilience was positively correlated with feelings of happiness and positive emotion. Second, social maladaptation and depression had a negative influence on resilience and a negative influence on happiness. Resilience had a mediating effect on mental health and feelings of happiness. Resilience had a mediating effect on mental health and positive emotion, while resilience had a mediating effect on mental health and negative emotion. In conclusion, in order to improve happiness it is important to mediate on intermarried Korean men's resilience through special education programs and counseling.

The objective of this study was to investigate the relationship between changes in body temperature, adiposity and sympathoadrenal activity in normal weight female college students, eating an instant-noodle lunch in a laboratory setting at ambient temperatures of 22-24.8$^{\circ}C$. Preprandial epinephrine(EPI) concentration, as an indicator of adrenal activity, was inversely and significantly correlated with body weight, body mass index(BMI), and waist girth. Changes in pre- and postprandial EPI concentrations showed positive correlations with % body fat, fat mass, waist girth, hip girth, and waist/hip girth ratio(WHR). The preprandial norepinephrine (NE) concentration was negatively correlated with recovery time from the peak postprandial core temperature to the meal-start core temperature(RTST). However, the NE concentration, an indicator of sympathetic neural activity, was not related to anthropometric measurements in normal weight young women. In conclusion, adrenal activity was negatively associated with adiposity and central body fat distribution. Sympathetic activity was related to body temperature regulation capacity after a meal, but was not related to adiposity in normal weight young women. (Korean J Nutrition 31(7) 1130-1138, 1998)

Objectives: The purpose of this study was to identify the relationships among violent experiences, positive psychological capital, and burnout, as well as to clarify the factors that affect psychiatric ward nurses' burnout. Methods: A descriptive research design was used. Participants were 213 psychiatric ward nurses recruited from twelve psychiatric hospitals. A structured self-report questionnaire was used to measure the study variables, and data were analyzed with the SPSS 24.0 program using descriptive statistics, an independent t-test, a one-way ANOVA, Pearson's correlation coefficients, and multiple linear regression analyses. Results: Burnout positively correlated with violent experiences (r=.14, p=.041), but negatively correlated with positive psychological capital (r=-.73, p<.001). Positive psychological capital was a significant variable for the burnout of psychiatric ward nurses (${\beta}=-.71$, p<.001). Conclusions: The study findings indicate a need to reinforce positive psychological capital for preventing and alleviating burnout of psychiatric ward nurses.

The teleconnections between El Nino/Southern Oscillation (ENSO) and droughts in Korea and the continental United States(U.S.) are investigated using cross analysis. For this purpose, monthly ENSO data and Palmer Drought Severity Index (PDSI) for Korea and for seven states in the U.S. are used. This study shows that there are significant statistical associations between ENSO indices and PDSI for Korea; however, the associations are very weak. It is found that dry conditions in Korea are positively correlated with El Nino, while wet conditions with La Nina. SOI, SSt in the Nino 4 and Ship track 6 regions among ENSO indices are more strongly correlated with PDSI than the other ENSO indices when using the original standardized data, but the SST Nino 3, SST Nino 4, and Darwin SSP exhibit abetter correlations with PDSI when using filtered data to be removed autocorrelation components of the original standardized data. The response time lag for maximum correlation between ENSO indices and PDSI appears to be affected by filtering the data. This is expecially true for Korea than for state analyzed in U.S. In addition, it is found that the PDSI in the continental U.S. is more strongly correlated wiht ENSO than in Korea. Furthermore, in analyzing the El Nino and La Nina aggregate composite data, it is found that the dry anomalies in Korea occur from the year following El Nino to about tow years after while the wet anomalies occur from La Nina year for a period of about two years.

Objective: The relationship between water-holding capacity (WHC) and intermuscular fat (IMF) was studied in Japanese commercial pork. Methods: Longissimus muscles of pigs (n = 62), obtained from two meat packing plants, were analyzed for IMF content, moisture content, drip loss, cooking loss, and pH. Pairwise relationships among these traits were determined using correlation analyses. Results: IMF content was significantly correlated with moisture content (r = -0.88; p<0.01) and pH (r = 0.32; p<0.05), but not with drip loss (r = -0.23; p = 0.07) or cooking loss (r = -0.10; p = 0.42). In contrast, drip loss was significantly (and negatively) correlated with pH (r = -0.57; p<0.01). Conclusion: IMF content was not significantly correlated with WHC in pork, and so ultimately, we consider pH to be one of the most important factors influencing WHC in pork meat.

The objective of this study was to investigate the relationship between muscle fiber characteristics, intramuscular fat (IMF) content, and fatty acids composition in longissimus lumborum (LL) muscle from Hanwoo steers. The LL muscles were obtained from four quality grades (QG) carcasses and subjected to histochemical analysis. There were significant (p<0.05) differences in fiber number percentage (FNP) and fiber area percentage (FAP) of muscle fiber types among muscles from four QGs. Both FNP and FAP of type I increased while those of type IIB decreased with increasing QG from QG 2 to QG $1^{{+}{+}}$ (p<0.05). Also, with increasing QG, the saturated fatty acid (SFA) proportion decreased while monounsaturated fatty acid (MUFA) increased significantly (p<0.05). IMF content was positively correlated with both FNP and FAP of type I, but negatively correlated with those of type IIB. The proportions of SFA and MUFA were significantly (p<0.001) correlated with both type I and IIB composition. These results implied that muscle fiber type composition is an important factor influencing fatty acid composition in LL muscle of Hanwoo steer.
