Using an overlapping generations model, this paper examines tax policy effects across generations. The model incorporates housing assets separately from capital assets and includes taxes on labor income, capital income, consumption and housing assets. Tax reforms for each tax rate have different effects on tax burdens across generations and the overall efficiency of the economy, leading to different welfare costs for generations. Specifically, raising housing property taxes results in the smallest welfare loss by future generations, as in the model it does not hurt economic efficiency and the tax burden increases mainly for the elderly, who have accumulated housing assets in preparation for retirement.

The purpose of this study was to examine the needs of apartment residents for community programs by generations. For this study, the data from the focus group interview(35 participants) and the questionnaire survey(186 participants) were analyzed. The major results were as follows; 1) The residents in different generations had different characteristics and life values. Y generation showed higher value in Technology/Consumption/Individual than other generations. BB generation had higher value both in Health/Property/Family and Prudence/Reality. G generation scored a higher level in Tradition/Conservatism. 2) The residents in all generations showed a high level in needs of community programs and especially higher rates in needs of communication programs items. However, there were gaps in program needs among different generations. Therefore, the community programs should be specialized provided by considering unique needs of different generations.

Objective: We report monitoring conservation effect for a Chinese indigenous chicken (Langshan) breed using major histocompatibility complex (MHC) and DNA barcords. Methods: The full length of MHC B-G gene and mitochondrial cytochrome oxidase I (COI) gene in generations 0, 5, 10, 15, 16, and 17 was measured using re-sequencing and sequencing procedures, respectively. Results: There were 292 single nucleotide polymorphisms of MHC B-G gene identified in six generations. Heterozygosity (He) and polymorphic information content (PIC) of MHC B-G gene in generations 10, 15, 16, and 17 remained stable. He and PIC of MHC B-G gene were different in six generations, with G10, G15, G16, G17 >G5>G0 (p<0.05). For the COI gene, there were five haplotypes in generations 0, 5, 10, 15, 16, and 17. Where Hap2 and Hap4 were the shared haplotypes, 164 individuals shared Hap2 haplotypes, while Hap1 and Hap3 were the shared haplotypes in generations 0 and 5 and Hap5 was a shared haplotype in generations 10, 15, 16, and 17. The sequence of COI gene in 6 generations was tested by Tajima's and D value, and the results were not significant, which were consistent with neutral mutation. There were no differences in generations 10, 15, 16, and 17for measured phenotypic traits. In other generations, for annual egg production, with G5, G10, G15, G16, G17>G0 (p<0.05). For age at the first egg and age at sexual maturity, with G10, G15, G16, G17>G5>G0 (p<0.05). Conclusion: Combined with the results of COI gene DNA barcodes, MHC B-G gene, and phenotypic traits we can see that genetic diversity remained stable from generations 10 to 17 and the equimultiple random matching pedigrees conservation population conservation effect of Langshan chicken was effective as measured by these criteria.

This research applied an attachment theory to the study of three generations of women. Questionnaire and semistructured interview techniques were employed to collect the data on intergenerational mother-daughter relationships from 140 triads of adolescent daughters middle-aged mothers an old-aged grandmothers. The focus of the study had been on the characteristics of attachment patterns which is measured by sense of attachment and autonomy across and within generations and their effects on personal well-being. Women in each their three generations perceived a high and seminilar level of attachment across and within the generations. On the other hand the level of autonomy differed by the generations with middle-aged mothers showing a higher level of perceived sense of autonomy than other two generations. Although the levels of attachment and autonomy were related to psychological well-being the level of autonomy was slightly more related to it. The results also showed that not nly one's own attachment toward mother/daughter but attachment of others toward herself were associated with the personal well-being. Overall this study reflects and supports the basis concepts of mother-daughter attachment: its continuity reciprocity and personal development in adulthood.

The objectives of this study are to identify life style of X-generations in seoul, and to examine housing preference of X-generations. Data was collected through self-administered questionnaires for this study and the cases of four hundred and sixty one were analyzed. The major findings are as follows:There were four major types of X-generations want to reside in 102-135㎡ (30-40pyung) housing size. They want the specific space for leisure, working, interest, computer, sports, dressing, etc. They prefer L-DK type, kitchen furniture of a island shaped work center. X-generations consider facilities of apartment very important. They want to have automatic and high quality facilities. Housing preference differed significantly according to the socio-demographic variables and the types of life style of X-generations.

This study had two goals: 1) to explore generational differences in traditional family rituals and 2) to investigate the association between family values and family rituals. Using survey data from 500 married men and women in their 20s to 60s, we classified three generations: 1) 1941-1950 birth cohort (aged 59-68), 2) 1951-1970 birth cohort (aged 39-58), and 3) 1971 and later cohort (aged 38 or less). These generations represented post-colonialism, modernization, and the information era in Korea, respectively. The results demonstrated that birth-related traditional family rituals had been maintained across the generations. Ancestor worship was less likely to be observed by later generations. Further, the way in which family values was associated with family rituals differed across the generations, indicating that traditional family values had different influences on everyday family life culture across generations.

Nuclear power generations have been developed gradually since 1950. Nowadays, 440 nuclear power generations are taking charge of 16% of electric power production in the world. The most important factor to operate the nuclear power generations is safety. It is not easy way to control nuclear power generations with safety because nuclear power generations are very complicated systems. In the main control room of the nuclear power generations, about 4000 numbers of alarms and monitoring devices are equipped to handle the signals corresponding to operating equipments. Thus, operators have to deal with massive information and to grasp the situation immediately. If they could not achieve these task, then they should make big problem in the power generations Owing to too many variables, operators could be also in the uncontrolled situation. So in this paper, automatic systems to diagnose the fault are constructed using 2 steps neural networks. This diagnosis method is based on the pattern of the principal variables which could represent the type and severity of faults.

Job competition among generations has become an important social issue that has yet to be studied from an academic viewpoint. This study performs statistical tests to investigate the interrelation of employment among generations using seasonally adjusted monthly time series data. Employment by generations is not found to be strongly interrelated, even if the employment of 30-year-olds appears to affect those of 40-yearolds in some tests.

The purpose of this study was to examine how the life styles of Korean people are influenced by the value systems of different generations. We analyzed the survey data of the 869 Korean participants aged from 20 to 69. The following results were obtained. First, differences exist among generations in various values such as collectivism, authoritarianism, environmental control, individualism , universalism, egalitarianism, and environmental accommodation. Especially, the older generation shows high scores in collectivism, authoritarianism and environmental accommodation, among traditional values. On the other hand, younger generation scored a higher level in individualism and egalitarianism. Second, there is a generation gap in the life style, as shown in family activities, household work, consumption activities, and leisure activities. In family activities, leisure activities and consumption activities, the younger generations gained higher scores than the older generations. Third, Korean people's value systems affect their life styles. Also, it was found that the interaction between the genera(ion and the value systems affects the life styles of Korean people.
