  • This study compares how mother-daughter differentiation influences solidarity and relationship satisfaction between mothers-in-law and sons-in-law. The subjects of this study were 167 mothers-in-law (mean age, 59.6 years) paired with their sons-in-law (mean age, 36.9 years). Participants were given quantitative survey questionnaires on their relationships. Descriptive statistical analyses were conducted for the social and demographic characteristics of mothers-in-law and sons-in-law. Ordinary least square multiple regression analyses were also conducted to examine the level of mother-daughter differentiation, solidarity, and relationship satisfaction between mothers-in-law and sons-in-law. The results show that a higher age of the mothers-in-law results in lower relationship satisfaction between mothers-in-law and sons-in-law. Next, an increase the level of mother-daughter differentiation (which means more balance between intimacy and detachability) results in a higher overall solidarity, affectual solidarity, giving functional solidarity, and consensual solidarity between mothers-in-law and sons-in-law. However, there was no statistically significant difference in the receiving functional solidarity and normative solidarity between mothers-in-law and sons-in-law. Finally, the results show that a higher level of mother-daughter differentiation produces a higher relationship satisfaction between mothers-in-law and sons-in-law. The findings could provide a better understanding of inter-generational relationships in Korean family dynamics. The results also have implications for providing counseling for the development of healthy relationships between mothers-in-law and sons-in-law.

  • The major purpose of this study was to investigate the effect of intergenerational transmission of self-differentiation on psychological adjustment of college students. Specifically, the present study endeavored to test the causal model focusing on the effect of the father's and the mother's self-differentiation on college student's psychological adjustment through the student's self-differentiation. The data were collected from 254 male and 293 female college students and their parents by using self-administered questionnaire method. The casual model was tested through structural equation model by using AMOS 7.0 program. The results showed that mother's and father's self-differentiation had direct and indirect effect on student's psychological adjustment. The results showed that both mother's and father's self-differentiation had direct effect on son's self-differentiation level, which directly influenced his psychological adjustment. The test of structural equation model also revealed that daughter's self-differentiation level was positively influenced only by mother's self-differentiation, while father's self-differentiation did not influenced female student's self-differentiation. Both male and female student's psychological adjustment was directly influenced by his or her self-differentiation level.

  • This study was conducted with 193 pairs of mother-in-law and son-in-law to examine the mediating effect of marital satisfaction on the relationship between interpersonal differentiation and affectual solidarity. Using SPSS and PROCESS macro program, descriptive statistical analysis(frequency, ratio, mean, and standard deviation) and mediating effect analysis through bootstrapping were performed. The main research results are as follows. First, in the case of the son-in-law, his own marital satisfaction completely mediated the relationship between the sub-factors of interpersonal differentiation (fusion with others, emotional cutting) and affectual solidarity. Second, in the case of mother-in-law, the perceived daughter's marital satisfaction partially mediated the relationship between the sub-factors of interpersonal differentiation (connectivity, separability) and affectual solidarity. These findings suggest the functional importance of the marital system for a healthy relationship between mother-in-law and son-in-law.

  • Structural differentiation of the connective stalk in giant duckweed, Spirodela polyrhiza, was examined to reveal the anatomical and ultrastructural characteristics within reduced shoot. The study focuses primarily on structural features of the connective stalk (CT), which connect offspring to their mother fronds. Photoautotrophic offspring fronds remained connected by stalks to mother fronds in the reproductive pockets until separation. The CT originated from the meristematic region of the abaxial frond and joined the fronds laterally with two abscission layers. The most notable features of the CT were polymorphic mitochondria, random occurrences of fibrillar structures in intercellular spaces, and great variability in cell wall thickness. Vascular tissues in CTs were highly reduced, demonstrating only a central vascular strand. Grana with 2 to 4 thylakoids and starch grains were found in the chloroplasts. A chlorophyll assay indicated high chlorophyll concentrations in daughter fronds and low concentrations in CTs. The frond and CT, while physically connected to each other, functioned independently. Despite great reduction in S. polyrhiza, the CT has proven to be very efficient for separating offspring from the mother frond, which lends to its capacity for rapid vegetative reproduction. The ultrastructural aspects of CTs in S. polyrhiza were characterized for the first time in this study.

  • The objective of this research was to investigate the influence of various root media on the growth of mother and daughter plants during propagation and early yield after transplanting of 'Seolhyang' strawberry. To achieve this, daughter plants were fixed to connected small pots that contained expanded rice-hull (ERH), a strawberry-specialized commercial medium (SSCM), soil mother materials (SMM), or loamy sand (LS). Then, growth of daughter plants in above- and below-ground tissue as well as early yield after transplanting to plastic house soil were investigated. The growth of daughter plants in terms of plant height, leaf area and fresh weight were the highest in the SSCM treatment. Root growth in terms of the amount of primary roots and root dry weight were the highest in the treatments of ERH and SMM and the lowest in that of SSCM, among treatments tested. The ERH treatment also showed the highest values among treatments in root length, surface area and volume when roots with 0 to 0.4 mm in diameter were investigated. The flower bud differentiation of daughter plants began on Sept. 3 in the ERH treatments, earlier than the SMM (Sept. 5) and in SSCM (Sept. 7) treatments. The tissue N contents of daughter plants were in the range of 1.41 to 1.55% in all treatments, and no significant differences were observed among treatments. This indicates that the low moisture retention capacity of ERH and water stress, rather than tissue N contents, promote the flower differentiation of daughter plants. In the evaluation of early yield after transplant, the ERH treatment of showed the highest yield in the period from November to December, reaching 667 g fruit weight per 10 plants. The yields per 10 plants in the other treatments were 581 g in SMM, 475 g in SSCM and 295 g in LS. Above results imply that the various root media have different effects on the growth of daughter plants as well as flower bud differentiation. Therefore, improvement in early yield after transplant can be achieved through selection of proper root medium for daughter plant propagation.

  • Aspects of structural differentiation of the free -floating hydrophyte, Spirodela polyrhira, has been investigated. The hydrophyte exhibited highly reduced structures having only fronds, connective stalks, and roots as a mature plant. The fronds were major photosynthetic and vegetatively reproducing organ during the growth. Daughter fronds which developed early in the mother frond were also chlorenchymatous, but they remained within foliage sheaths of the mother frond before separation from connecting stalks. Although the stalks and roots originated from the same meristematic region of the frond, they exhibited the distinct polarity showing former lateral growth and latter axial growth. Air chambers were formed only in the fronds and roots. Cellular components were scattered throughout the diffuse cytoplasm in most of the actively growing stalk cells. Root cells protected by the root cap demonstrated relatively complex organization, showing dense cytoplasm with Golgi, rER, mitochondria, and chloroplasts in the cortical cells. Cells in the root cap were highly vacuolated within the peripheral cytoplasm. Such reduction and differentiation of the plant body in Spirodela polyrhiza most effectively contributes to the better adaptation of smaller plants to superficial aquatic environments, while also enabling the rapid growth.
