The effects of the proprotion of cows inseminated by young A. I. bulls on genetic improvement in the Japanese Holstein population were examined using a simulation technique. The proportion of recorded cows inseminated by young A. I. bulls was assumed to be from 10% to 100% of the total number of recorded cows. The expected total genetic improvement was estimated for all cows and recorded and non recorded cows. The effects of the above were remarkable in the schemes that proven sires were used to produce recorded and non recorded cows for a limited time. Also the increase in the rates for -the expected total genetic improvement was larger when the proportion of recorded cows that were inseminated by young A. I. bulls was about 10% to 40%. When the expected total genetic improvement was estimated for the entire population, we found that the highest values were in a range of about 40 to 60% recorded cows that were inseminated by young A. I. bulls. On the other hand, the expected total genetic improvement that was only estimated in recorded cows dramatically decreased for more than 40% of the recorded cows. The results of this study showed that the optimal proportion of recorded cows inseminated with young A. I. bulls should be about 30% in the Japanese Holstein population.

The purpose of the research is to evaluate how education influences the income of household heads, who are young adult in rural Vietnam. In order to examine the impact of education on the households where their heads are young adults, in this paper, the authors employ two research methods. First, ordinary least squares (OLS) regression is used to study the impact of education on different groups of income; second, quantile regression is applied to find out how education influences the income of households. The dataset includes a survey of 800 young households aged between18 and 35 who are the head of agricultural farms in rural areas. The findings indicate that education has a positive impact on income of young households. Furthermore, the results prove that the longer schooling years, the higher income youth can attain. The results showed that, at the survey time (Sep 2019), the average monthly income of rural young adults who are joining the production process shows a big gap between low and high incomes. Moreover, the study has revealed that other factors positively affect the incomes, namely, joining job-related associations, land resource, hired labour, hi-tech application as well as extension of producing unit.

This study was aimed to develop an integrative art program that incorporates both emotional and pro-social components for young children (age, 4-5 years). Furthermore, the effectiveness of this integrative program was examined with 39 young children who were divided into the experimental group and the control group of this study. To the experimental group, the integrative art program of interest in this study was provided over 8 weeks. The children of the control group were provided a similar program during the same period. To measure the levels of young children's emotional intelligence and those of their pro-social behavior were assessed by using the emotional intelligence questionnaire and the children's pro-social behavior assessment scale to collect the data. The analysis of covariance by SPSS 18.0 indicated that the young children from the experimental group exhibited higher total scores for emotional intelligence and pro-social behaviors than their counterparts from the control group. The results indicate that the integrative art program of interest in this study improved the young children's emotional intelligence and their pro-social behaviors. Along with main results of this study, implications for research and practice were discussed.

Purpose : This study is to see the existence of the meridian and the meridian point through their response to the Young-Su-Bo-Sa. Objective and Methods : For this purpose, with acupuncture stimulation with Young-Su-Bo-Sa on the Hapkok of left hand and an the non-meridian point, and using the Digital infrared thermal image(D.I.T.I), We observed and analyzed the thermal changes of Hapkok, Samgan, non-meridian point(NA), Yonghyang, Soryo, Chonchu, Shingwol. Results and Conclusions : To sum up, We could understand Young-Su-Bo-Sa stimulation through the study findings that the acupuncture stimulation on the meridian point caused significant thermal changes of the associated meridian and meridian point, and Young-Su-Bo stimulation given in the direction of the meridian passage caused increases in the thermal changes of the associated meridian point, while Young-Su-Sa stimulation caused decreases in the thermal changes of the associated meridian point.

Securing manpower in rural areas is critical to improving the productive potential and overcome challenges caused by changes in the demographic structure and the need for diversification of the rural economy. This underpins the importance of nurturing young farmers in order to enhance the agricultural competitiveness in the rural areas. On the other hand, 42.3% of young farmers under the age of 40, which is the target age of the government-sponsored program to foster young farmers, grow rice. Meanwhile, 42.3% of the farmers are under 40 years of age which is a category of farmers targeted under the government sponsored program to advance rice production. In this study, a bivariate probit model is used to conduct substantive analysis on the potential political interventions that would persuade young farmers in the rural areas to participate in rice production in the 6th industry. In summary, most important factors identified as to influence participation of young farmers in the diversification of crop production are the utilization of information device, land, ownership of agricultural machinery, and the leasing of the cultivating land.

A study on what kind of problems young consumers experience in buying and using mobile phone services with a comprehensive and consumers oriented perspective is needed. Through this acknowledgement, we investigated (i) the degree of consumer problems that young consumers experience in purchasing and using mobile phone services, and (ii) the related variables that affect experiences of this consumer problem. The parents of the teenagers were also included in the survey because they experience the same problems young consumers' experience in buying and using mobile phone services. Data were gathered through an internet survey (www.embrain.com) and a total of 699 samples from 350 parents and 349 youths using mobile phone services were analysed. The results are as follows. First, the teenagers and parents' experience level of young consumers' problems were generally high experiencing similar kinds of problems. Second, parents experienced more young consumers' problems than the teenagers in buying and using mobile phone services, especially in misuse and abuse of the phones. Third, among the teenagers, the monthly usage fee music or game usage, the number of changes in mobile phone service operators, the number of replacement mobile phones and the gender had a significant effect on consumers' problems of mobile phone services. Among the parents, the monthly usage fee, music or game usage, confirmation of the bill, and the gender of their child were significant consumer problems.
