The purpose of this study is to investigate the change of hamstring muscle relaxation and craniosacral reciprocal movement by using S. O. T. (sacrooccipital technique) categoryⅠ block-intervention process. 26 subjects with heel tension were randomly divided into two groups (EXP=13 and CON=13). This study carried out the category I block-intervention process on the experimental group and the false block-intervention process on the control group. Then, this study measured the sit-and-reach and sacral reciprocal movement of subjects before and after the intervention. The result values before and after the intervention were analyzed through ANCOVA by using SPSS PC Program (Ver. 20.0). In both investigations, the degree of hamstring muscle relaxation and the change of sacral reciprocal movement, there were statistically significant differences between the experimental group and the control group as [F(1, 23)=7.73, p<0.5] and [F(1, 23)=7.07, p<.05] respectively. According to the results of this study, it is expected that S. O. T category I bllock-intervention technique will have positive effect on both hamstring muscle relaxation and craniosacral reciprocal movement.

Steers and heifers (N=490) were produced between 1991 and 1996 by reciprocal fiillsib backcross and $F_1$ crosses from Angus and Brahman to compare characteristics of carcass and palatability traits between Bos indicus and Bos taurus inheritance. Carcasses of 3/4Angus were heavier, fatter (p<0.05), more tender and higher in other palatability attributes (p<0.01) than those of 3/4Brahman. Reciprocal effects of parental cross breeds were found on some traits. Within 3/4Brahman inheritance group, Brahman sired progeny produced heavier and fatter carcasses with better palatability (p<0.05) than progeny with Brahman as a dam breed. Estimates of heritability were intermediate to high in most carcass and palatability traits. Genetic correlations of tenderness with marbling score (MARB), sarcomere length (SARC), fragmentation index (FRAG) and calpastatin activity (CALP) were moderate to high, suggesting potential use of the tenderness-influencing factors as indirect selection criteria to improve palatability attributes. MARB and SARC that were best predictors of tenderness explained 3.07 to 5.85% and 4.32 to 8.24% of variation in tenderness, respectively. However, there was no tenderness-influencing factor to dominantly explain large portion of variation in tenderness.

Purpose: This study examined the reciprocal relationships between depression and income, and gender differences in these relationships among older adults in South Korea. Methods: Using 2015 to 2019 of the Korea Welfare Panel Study (KoWePS), we studied 6,070 older adults (2,394 men and 3,676 women) aged 60 years over in 2015. The generalized estimating equation was employed to explore the effect of an individual income on depression and the reverse causal link-that of depression on income. Results: The study found the reciprocal relationships between income and depression. Income has a significant impact on depression. Higher-income was linked to decreased risks of the Center for Epidemiologic Studies Depression (CES-D) scores among older adults (B = - 0.121, p < 0.001). Estimates of the reverse causal link show that higher CES-D scores were also linked to income reduction among Korean older adults (B = - 0.007, p < 0.001). In addition, we also observed gender differences in the impact of income on depression but not in the reverse causal link. Income has more detrimental to psychological consequence for older men (B = - 0.108, p < 0.001) than older women (B = - 0.057, p < 0.001). Conclusion: The finding implies that both psychological and social protection policies for the elderly are needed in view of gender perspective.

In Erhualian and Yorkshire reciprocal cross $F_1$ pig populations, we examined the mRNA expression characteristic of liver-derived IGF-1, IGF-1R, IGF-2, IGF-2R and IGFBP-3 during the embryonic and postnatal developmental periods (E50, E70, E90, D1, D20, D70, D120 and D180). Our results demonstrated that the IGF-system genes mRNA levels exhibited an ontogenetic expression pattern, which was potentially associated with the porcine embryonic development, postnatal growth, organogenesis and even the initiation and acceleration of puberty. The expression pattern of IGF-system genes showed variation in the reciprocal cross ($F_1$ YE and EY pigs). This study also involved the expression features of imprinted genes IGF-2 and IGF-2R. The parent-of-origin effect of imprinted genes was reflected by their differential expression between the reciprocal crosses populations. The correlation analysis also indicated that the regulatory network and mechanisms involved in the IGF system were a complex issue that needs to be more fully explored. A better understanding of IGF system components and their interactive mechanisms will enable researchers to gain insights not only into animal organogenesis but also into somatic growth development and even reproduction.

In this study, the effects of reciprocal peer tutoring strategy on science achievement, science learning motivation, and self-esteem were investigated. Three classes of eighth graders (N=94) at a coed middle school were sampled for the study. They were divided into the comparison group, the cooperative learning (CL) group, and the reciprocal peer tutoring (RPT) group. Students were taught about the separation of mixtures for 13 class hours. Mid-term science examination scores were used as a blocking variable. The two-way ANCOVA results revealed that there were no significant differences among the three groups in the science achievement test, although the scores of the RPT group were higher than those of the comparison group. In all the subtests of the science learning motivation questionnaire, the scores of the RPT group were significantly higher than those of the comparison group. The scores of the RPT group were significantly higher than those of the other groups especially in the confidence part of the science learning motivation questionnaire. In the self-esteem test, the low achievers in the RPT group scored significantly higher than those in the CL group.

Recently, learning how to learn is a matter of concern among many pedagogists and become the important subject matter of school education. That's why there are many learners who fail to get good results compared with their potential abilities and efforts, as well as the necessity to educate independent and self-determined learner by teaching learning strategies that can help leaners to get new information and skills by themselves in an information-oriented society was emphasized. Therefore, this study is to utilize the learning strategy in order to improve the learners study skills, and grope for the method of self-directed learning about the social studies centered on the learners. And, it is to utilize the reciprocal teaching with the learning strategy for improving the learners study skills. Also, it is to make the learners induced to participate in the teaching for social studies actively, grafting the characteristics of web on the reciprocal teaching. According to this intent, this study was developed as three steps. As for the first step, it investigated the reciprocal teaching, a teaching-learning theory to apply to the program, and the theoretical background about web utility in the social studies. On the second step, it embodied the reciprocal teaching-learning system about the we-based social studies that will be available in the self-directed learning centered on the learners. Lastly, it analysed the change of recognition about the learners social study skills and the learning the social studies after applying the materialized website to the actual lesson.

The present research investigates the reciprocal effects of a previous brand extension and follower brand extension's market performance on a parent brand of a follower brand's extension product using 2(previous brand extension's market performance: success vs. failure)${\times}$2(follower brand extension's market performance: success vs. failure) between-subjects factorial design. The verification of the hypothesis is composed through 2-way ANOVA. As a result, the consumers' evaluation of the parent brand of a follower brand's extension product when the follower brand's extension succeed was more positive when the previous brand's extension has failed. However, when the follower brand's extension has failed, the consumers' evaluation of the parent brand of a follower brand's extension product was more negative when the previous brand's extension has succeeded.
