This study examined the relationship between parent-child relationship experiences in childhood and adulthood, and individual development and psychological well-being in mid to later life using structural equation modeling with data from 1,882 parents who have at least one child over 18 years old. Findings indicated that receiving more affectionate parenting in childhood was associated with greater generativity development, more positive parental experiences with one's own children, and better psychological well-being in mid to later adulthood. In addition, the effects of received parenting in childhood on psychological well-being after midlife were partially mediated by parental experiences with adult children and generativity development. These findings suggest that early experiences with parents in childhood continuously influence psychological well-being in adulthood through their impact on concurrent family experiences. However, early influences can be redirected through adult experiences too. These findings have implications for the development of intervention programs aimed at promoting volunteer work for older adults, as well as for practitioners who work with families and individuals who are having problems.

Adult child caregivers and spousal caregivers might deal with differential challenges. Studies about caregivers' psychological outcomes, however, tended to investigate associations between caregiving and its outcomes by pooling adult child caregivers and spousal caregivers together. By using a U. S. sample of family caregivers who assisted a relative with dementia, this study examined whether the relationship of caregivers to care receivers (daughter caregivers or spousal caregivers) made a difference in levels of depressive symptoms. The result showed that wife caregivers were more likely to be depressed than daughter caregivers. For daughter caregivers, role overload, role captivity, and behavior problems significantly influenced on depression. Besides these variables, the level of education was a significant predictor for wife caregivers. Role captivity and behavior problems significantly impacted on depression for husband caregivers. Thus, role captivity and behavioral problems were common predictors for all the caregivers. Specifically, higher levels of role captivity and behavioral problems were likely to make caregivers more depressed. The implication of these results were discussed.

The present study explored psychosocial characteristics of infants with genital anomalies (GA) and their caregivers against normal controls. Participants were female caregivers and infants between the ages of 6to38months diagnosed with hypospadias(HS;n=103) or cryptorchidism (CR;n=49). Normalcontrols(n=131) were recruited and selected via Internet. Caregivers completed measures on parenting stress, coping style, social support, and infant temperament. Within the GAgroups, HScaregivers reported their greatest parental concerns as infant urination/bodily functioning difficulties whereas CRcaregivers reported worries related to surgical anesthesia issues. Both groups reported concern about their children's potential reproductive problems. Per caregiver report, infants with GA had lower ability to self-soothe. HS infants in particular were perceived as exhibiting greater negative emotion. Compared with controls, HS and CRcaregivers overall employed coping strategies more frequently and had lower interpersonal sensitivity and parental distress. However, HScaregivers emerged as experiencing higher stress when compared to the CRgroup. There were no differences in to tal parenting stress and social support scores between groups. Further, CRcaregivers reported lower levels of family discord than controls. Despite temperament-related differences between infants with GA and normal controls, HS and CRcaregivers reported lower parental distress and greater use of coping skills as compared to controls. Clinical implications are discussed.

This study examines the labor market performance of graduates who had student loans. Compared to earlier studies, we extended analyses to all jobs that were experienced for more than 18 months after graduation. First, we found that students who had student loans earned 2.81% less at their first job compared to their counterparts without student loans. Second, the wage gap decreased over time, a reduction of 0.66%p due to labor market turnovers. Third, when we compared cumulated labor income, however, the amount for borrowers were continuously higher. This is because the job searching period of a borrower was shorter, despite relatively lower wages at the first job, and borrowers also made more frequent job turnovers, accompanying relatively more wage increases. These results suggest that the negative effects of college loans on earnings, reported in previous studies, may have exaggerated the negative impact to some extent of having loans. However, when we look at the quality of jobs beyond simply wages, the proportion of borrowers working at large companies as regular workers was consistently low. Given that job conditions at the earlier stages of one's career may lead to gaps over time, our findings call for more systematic investigations into the effects that student loans have on long-term labor performance.

The implicit association test (IAT) measures implicit attitudes of participants and is regarded as an effective method for expecting future behaviors. Based on the IAT, this study aimed to answer the question, whether implicit attitudes of an individual about creativity have any kinds of impact on global perception, which might be important for a creative process. In the experiment, participants were presented words, which were associated with one of four categories, while one attitude category (creativity /practicality) and one evaluative category (good/bad) were always paired together either on the left side or on the right side of the computer screen. After completing the IAT test, participants were led to fill out a questionnaire to assess explicit attitudes toward creativity and practicality. Then they conducted the navon task, in which they had to find one of two letters, 'F' or 'H', which were presented either as a local form or as a global form. Finally, the participants had to write down as many untypical functions of an object as possible. The results showed that not the scores of explicit attitude scores but the IAT scores correlated with the reaction time of global perception. The global perception was faster in the participants with the low IAT scores than the local perception. Compared to this, the global perception benefits disappeared in the participants with the high IAT scores. Additionally, more creative ideas about the functions of the object were listed in the group with the lower IAT scores. Implications of the role of implicit attitudes about creative processes are discussed.

Purpose: The purpose of this study was to examine the impact of 12 Lactobacillus strains and four yeast mixed fermentation broth on the blood characteristics of subjects who consumed for eight weeks. Methods: Blood samples taken from the subjects and clinicopathologic blood components examined. Results: In the white blood cell count the mean pre-test value of the experimental group consumed Zen fermentation broth was 5.73×10³ cells/µl, and the mean after-treatment was 5.37×10³ cells/µl, but the difference was not significant. The control group was not significant. In the hemoglobin content, the mean value before the intake of the Zen-test group was 13.58 g/dl, and the consumption after the consumption was 14.77 g/dl, which significantly increased. Albumin content was 4.33 g/dl before intake and 4.36 g/dl after ingestion in the Zen-test group, but it increased without significance. Triglyceride content was 109.8 mg/dl in the Zen-test group and 99.83 mg/dl in the post-test group, but it was not significant. In the LDL-content the mean of the premeasured value was 109 mg/dl in the Zen-test group, and that of the post-test was 97.87 mg/dl, and the difference significantly decreased to 11.13 mg/dl. In the HDL content, the mean value of the pre-test was 51.4 mg/dl in the Zen-test group and 56.87 mg/dl in the post-test. Conclusion: After intake of Zen fermentation broth, mean values of leukocyte, albumin, and triglyceride were not significantly different in the experimental group, but hemoglobin, LDL and HDL were significantly different.

Various drought indices are widely used for assessing drought conditions which are affected by many factors such as precipitation, soil moisture, and runoff. The values of drought indices varies depending on hydro-meteorological data and calculation formulas, and the judgment of the drought condition may also vary. This study selected four calculation components such as precipitation data length, accumulation period, probability distribution function, and parameter estimation method as the sources of uncertainty in the calculation of standardized precipitation index (SPI), and evaluated their contributions to the uncertainty using root mean square error (RMSE) and linear mixed model (LMM). The RMSE estimated the overall errors in the SPI calculation, and the LMM was used to quantify the uncertainty contribution of each factor. The results showed that as the accumulation period increased and the data period extended, the RMSEs decreased. The comparison of relative uncertainty using LMM indicated that the sample size had the greatest impact on the SPI calculation. In addition, as sample size increased, the relative uncertainty related to the sample size used for SPI calculation decreased and the relative uncertainty associated with accumulation period and parameter estimation increased. In conclusion, to reduce the uncertainty in the SPI calculation, it is essential to collect long-term data first, followed by the appropriate selection of probability distribution models and parameter estimation methods that represent well the data characteristics.

As various wheat variety for bread, all-purpose, and cake flour have been developed, suitable cultivation method for the end-use of the new variety need to be revised. This study was conducted to suggest an optimal nitrogen(N) fertilizer method for wheat Variety 'Saekeumgang' and 'Hojoong' with good noodle quality. In order to analyze the yield and quality changes of 'Saekeumgang' and 'Hojoong' as nitrogen fertilizer amount and timing, these varieties were sown on paddy soil in jeunju, Republic of Korea. The amount of N fertilizer was divided into 4 levels (7.1, 9.1 11.1,13.1kg/10a). In each levels, N amount in sowing date fixed as 3.6kg/10a, N amount in 10 days after heading(DAH) were treated 0 or 2kg/10a, and the other N amount was treated in regrowing stage. As N amount in regrowing stage increased, culm length of 'Saekkeumgang' was increased, but culm length of 'Hojoong' was not affected. Spike number/m² was increased when N fertilizer amount in regrowing stage increased as 3.5 to 7.5kg/10a. But, spike number/m² wasn't increased compared N amount 7.1kg/10a conditions when N fertilizer amount 9.1kg/10a. When the N fertilization amount in regrowing stage was increased by 1kg/10a, grain yield increased by 45.7 kg/10a in 'Saegeumgang' and 21.4kg/10a in 'Hojoong', so the fertilizer effect of 'Saegeumgang' was higher, when N fertilizer amount was increased to 2kg/10a at 10DAH, 1000-grain weight increased, but spike number/m2 and grain yield were not affected by N fertilizer at 10 DAH. Protein content and SDS-sedimentation value were increased as increasing N fertilizer amount in regrowing stage and 10 DAH. Among them, N fertilizer amount in 10 DAH had higher impact on protein content and SDS-sedimentation value. As N fertilize in 10 DAH, hardness of noodle was increased and chewiness of noodle was decreased

In this paper, mortar mixed with tapioca starch was manufactured to evaluate the effect of tapioca starch on mortar, through evaluating the quality characteristics of mortar, the impact of tapioca starch on improving the performance and basic quality of mortar was examined. Tapioca starch tended to decrease flow by increasing the viscosity of the dough consistency of fresh mortar, which tended to reduce flow, and decreased by about 10 % as the tapioca starch mixing ratio increased by 0.025 %. In addition, the effect of tapioca starch on the compressive strength of mortar was at the same level regardless of the tapioca starch mixture at 28 days of age. However, at an early age of 3 days, the speed of compressive strength development was accelerated by mix ing tapioca starch. In addition, the effect of tapioca starch on the compressive strength of mortar was at the same level regardless of the tapioca starch mixture at 28 days of age. However, at an early age of 3 days, the speed of compressive strength development was accelerated by mixing tapioca starch. The speed of strength development improved by about 20 % when mixing 0.050 % tapioca starch. The adhesion strength improved by about 60 % when mixing 0.050 % tapioca starch, and the final shrinkage in length change decreased by 5 %.
