The Purpose of this study was to explore the generational conflicts around adult children's taking care of elderly parents and grandparents' caring for grand children. The results of this study were as follows. First, the child care responsibility of the parents' generation is much more intense than that of the parent care responsibility of the children's generation. Second, the norm of parent care has changed from being the responsibility of the eldest son to being the responsibility of all of the children, which had led to an increased probability of conflicts between the two generations due to the differences in expectation and reward. Third, the bilateralization of the kinship increases the responsibility of women in taking care of their families, which leads to an increase in conflict among women of different generations. Finally, the generational conflicts related to family care appear across different social classes.

In this short report (before the authors would like to introduce an important application for one of the techniques of complex angular momentunm, say, Regge Pole approach, to nuclear fusion reaction for Light-ions: it will be reported in forthcoming papers), two kinds of thermalnuclear fusion reaction sources are introduced and discussed (A) the case of fusion: the production of neutron and target of Deuteron and (B) the case of fusion: the production of proton and target of Deuteron. Nuclear fusion reactions for Light-ions , such as the thermalnuclear energy sources and fuel cycles, are already well known. Fusion reactions are widely known as being extremly important and nationally vital (in point of view of nuclear weapons we must reconsider seriously development and building of such dangerous weapons) for our next generations in the future. This paper (a topics in review) is concerned with a simple introduction about a new nuclear fusion reaction of the above case of (B) for the second generation. Typical thermalnuclear fusion reactions which result in the release of huge amount of energy are nuclear stripping reactions:

Influence of susceptible and resistant soybean varieties to the development of the soybean cyst nematode(Heterodera glycines) was examined. It does not seem likly that there are any differences between varieties in attracting the Second Stage larvae of the nematode. In susceptible varieties, there were large populations and three generations during a ten·week examination period, while the resistant varieties maintained very low populations and had only two generations.

Ore criteria at the Sheba Deposit indicate orogenic mineralization type. Rocks and mineral assemblages suggest low formation-temperature of green-schist facies. Pyrite found in two generations; Type1 is irregular grains, contains higher arsenic and gold contents, compared to the relatively younger phase Type2 pyrite, which is composed of euhedral grains, found adjacent to late quartz-carbonate veins or at rims of type1 pyrite. Two gold generations were identified; type1 found included in sulphides (mainly pyrite). The second gold type was remobilized (secondary) into free-lodes within silicates (mainly quartz). Gold fineness is high, as gold contains up to 95 wt. % Au, Ag up to 3.5 wt. %, and traces of Cu, Ni, and Fe. Pyrite type2 contains tiny mineral domains (rich in Al, Mn, Hg, Se, Ti, V, and Cr). Zoning, and replacement textures are common, suggesting multiple mineralization stages. The distribution and relationships of trace elements in pyrite type2 indicate three formation patterns: (1) Al, Mn, Hg, Se, Ti, V, Cr, and Sn are homogeneously distributed in pyrite, reflecting a synchronous formation. (2) As, Ni, Co, Zn, and Sb display heterogeneous distribution pattern in pyrite, which may indicate post-formation existence due to other activities. (3) Au and Ag show both distribution patterns within pyrite, suggesting that gold is found both in microscopic phases and as chemically bounded phase.

We consider two models for the growth of population with overlaping generations. First, the model we will describe is basically the model given by Leslie(1945). This is only a one-sex model of population age structure and growth. Next, we introduce a model in which couples must be formed before reproduction occurs. If the maximum number of couples is formed, and if the couples are only formed from fermales of age x-a and males of age x at time t, $\alpha$ > 0. Then, we will solve the renewal equations for the reproductive value.

This study was carried out to investigate the time-trends of genetic parameters of the dosed flock population which selected for improving egg production. Data for two layer pure lines, Line-W (Single Comb White Leghorn) and Line-B (brown layer) which have been maintained at the Mani Breeding Farm were collected from 1980 to 1985 during 5 generations. The effective number of parents per generation ranged from 148 to 366 in Line-W and 85 to 355 in Line-B, and the cumulative expected inbreeding coefficients during 5 generations of selection were 15％ and 1.6％. So inbreeding could not be considered a critical factor on estimating the genetic parameters, heritabilities and genetic correlations Heritabilities of EN 300 and EN 400, primary two selected traits were significantly decreased during 5 generations but the estimates of the other 03its not showed the consistent decreasing pattern significantly. No time trends of probable consequence were evident in the genetic correlation coefficients of the traits studied. The reason for that situation was attributed to the fact that selection was conducted for multiple objectives and the relative importance of selection for the studied traits were not consistent by generations.

Objectives: The purpose of this study was to compare the first echo boomer to second in the needs for family strengths and family functions, after controlling the sociodemographic characteristics. Method: For this study, a survey was conducted with 406 never-married young adults, which has 182 first echo boomers and 224 seconds echo boomers as using the same self-report questionnaire. Results: First, the two echo boomer groups exhibited similar patterns in their perception of the three family strengths, positive family values, pursuit of coexistence, and spiritual value, in that order. On the other hand, in regard to family functions, groups' perceived emotion entertainment leisure function as core functions of the family, but the second echo boomers, unlike the first echo boomers, expressed a higher need for economic functions rather than functions for children generation. Second, the analysis of this study indicated that, even in cases where first and second echo boomers had the same social-demographic characteristics, the latter in contrast with the former tended not to regard spiritual values such love for shared ethical values, compassion, and religious beliefs as a family strength, and did not require functions for children generation of the family. Conclusions: From these findings, the differences in the needs for family strengths and functions expressed by the two generations belonging to two different birth cohorts were influenced by various changes in Korean society occurring between the two generations, such as the social divergence in the functions of care and nurture, the increase in one-person and childless households, and the weakening of kinship-centered or communitarian forms of familism.

Objectives : Suwenliuqixuanzhumiyu is a book that strongly influenced the following generations' theory of five Circuits and six Qi. It is understood that Wangbing authored the book during the Tang dynasty, but another theory suggests that a nameless author devised the book falsely in Wangbing's name. A comprehensive research is greatly significant in the development of the theory of five Circuits and six Qi. Methods : The study will focus on the analysis on the truth about Suwenliuqixuanzhumiyu, its impact on the following generations' theory of five Circuits and six Qi, the contents and comparison of Suwen's xuanzhumiyu, and the 17 books and 27 chapters of xuanzhumiyu. Results & Conclusions : First, xuanzhu was authored by Wangbing sometime around 762 AD, and Suwenliuqixuanzhumiyu was written in 690 during the rule of Empress Wu Zetian, meaning that Wangbing is not the author of Suwenliuqixuanzhumiyu. Second, Wangbing's style of writing is regular yet elegant, and keeps itself within the range of medical style of writing, but Suwenliuqixuanzhumiyu is written in a very rough style, and finds itself within the range of Tao literatures and books on trickery. Third, Wangbing's xuanzhu is a commentary on Suwen, whereas Suwenliuqixuanzhumiyu is consisting of the theory of five Circuits and six Qi, and trickeries predictive picture. As such, the two books have entirely different characters. Theories that received relatively significant impacts to the following generations' the theory of five Circuits and six Qi include Gandeokbu, Jeongwhadaewha, and the Calculation method of normal Qi. Suwen's chapter on the theory of five Circuits and six Qi and Suwenliuqixuanzhumiyu have many inconsistent and differing theories, leading the scholars to believe that they are dealing with different theory of five Circuits and six Qi which derived from separate schools of beliefs.

To investigate the fidelity of transgene transmission and expression, we produced transgenic mice carrying bovine $\beta$-casein/bovine grwoth hormone(bGH) fusion gene and examined transmission efficiency and expression level of the transgene in the founders and their progeny. The transgene was composed of 1.8 kb bovine $\beta$-casein promoter and 2.1 kb bGH gene. Ten transgenic mice were produced. Milk and mammary gland were collected from eight transgenic lines at 10-day lactation and a, pp.ied to Western and Northern blot analyses. The bGH expression was detected in four of them. The concentrations of bGH in milk were highly variable from 4$\mu\textrm{g}$/ml to 600$\mu\textrm{g}$/ml depending on the lines. The bGH mRNA level in mammary gland was closely correlated with the bGH concentration in milk in each transgenic line. These results indicated that bGH transgene expression was a, pp.opriately regulated in the mammary gland and secreted into milk in transgenic mice. By using two transgenic lines(#2, #7) secreting a considerable amoung of bGH into their milk, the inferitance and maintenance of transgenic phenotype were assessed in successive four generations. The mean transmission frequencies of transgene in lines #2 and #7 were 34% and 40%, respectively. The bGH concentration in milk were 80, 240, 120, 60$\mu\textrm{g}$/ml in each G0(generation 0), G2, G3, G4 generation of line #2 and 600, 1600, 860, 900$\mu\textrm{g}$/ml in each G1. G2, G3, G4 generation of line #7. These results demonstrated that bovine $\beta$-casein/bGH gene was stably transmitted from generation to generation in a Menelian fashion in trasgenic mice and consistenly expressed in their milk throughout the generations, although there was a little variation in the transmission frequency and expression level of the transgene between generations.

The purpose of this study is to provide empirical findings about intragenerational and intergenerational discrepancies in eldercare attitude and behavior in Korea. Specifically, intragenerational discrepancies refer to phenomena in which eldercare attitude and behavior diverge from each other within the caregiving and care-receiving generations, respectively. Intergenerational discrepancies, on the other hand, refer to two kinds of phenomena, one in which eldercare attitudes are different between caregiver and care-receiver and the other in which eldercare behavior is differently recognized between the two parties. For the last couple decades, these kinds of discrepancies tended to be simply assumed without any coherent theoretical and/or empirical rationales. Thus, the current study tried to investigate the degree, pattern, and characteristics associated with the discrepancies. Analysis of data collected from 276 matched pairs of caregivers (i.e., daughters-in-law) and care-receivers (i.e., the elderly) in Kwangju and its suburb areas has indicated a substantial amount of both intra- and inter-generational discrepancies. In other words, both caregivers and care-receivers were found to be experiencing huge discrepancies between attitude and behavior in their respective generation: the factual discrepancies in attitude between the two generations were quite salient: the cognitive discrepancies in behavior between them were salient, too. In addition, it was also found' that the extent to which the discrepancies became salient differed for the three subdimensions of eldercare (i.e., emotional, economic, and physical care), and that such discrepancies have intimate relationships with a set of sociodemographic characteristics for caregivers - notably, age, educational attainment, area of residence, household income - on the one hand, and those for care-receivers - notably, gender, age, educational attainment, cohabitation, family size, inheritance, owned property - on the other. A series of theoretical, empirical, and clinical implications stemming from the findings were suggested and fully discussed in the context of Korean society.
