This study empirically compared generational differences in responses between baby boomers, Generation X, and Generation Y groups as measured by key variables related to advertisement. The respondents in this study were consumers throughout Korea, with 914 survey questionnaires used for the final analyses. Eight of the original 10 hypotheses were validated and two were rejected. Both baby boomer consumers and Generation Y consumers showed more positive responses to affective advertisements than their Generation X counterparts. Generation Y consumers showed more positive attitudes towards humorous advertisements than their baby boomer and Generation X counterparts. The effect of advertising models on the evaluation of advertisements was greater among Generation Y consumers than their Generation X counterparts. Generation Y consumers showed more positive attitudes towards storytelling-type marketing than their baby boomer and Generation X counterparts. Baby boomer consumers showed more positive attitudes towards symbolic advertisements than their Generation X and Generation Y counterparts. Generation X consumers showed more positive attitudes towards functional advertisements than the baby boomer and Generation Y groups. There were significant differences in attitudes towards two types (symbolic and functional) of advertisements in both baby boomer consumers and Generation X consumers.

NGC 6273은 우리은하 중앙팽대부 영역에 위치하고 수평계열이 확장되어 있는 구상성단으로 초신성에 의해 중원소 함량이 증가된 2세대 종족의 존재가 의심되는 성단 중 하나이다. 이를 보다 면밀히 조사하고자 2011년 6월, 칠레에 위치한 Las Campanas Observatory의 2.5m Du Pont 망원경과 2K CCD를 이용하여 Ca, b, 그리고 y 필터로 측광 관측을 수행하였다. 중원소 함량에 민감하게 반응하는 hk (hk=(Ca-b)-(b-y)) 색지수로 색등급도를 그려본 결과 적색거성계열이 관측오차의 8배 이상으로 매우 넓게 퍼져있는 것을 발견하였다. 이러한 현상이 중원소 함량 차이로 인한 것인지, 아니면 성간소광효과나 배경별에 의한 영향인지를 분석하였고, 그 결과 중원소 함량의 차이가 있는 다중종족의 존재 가능성을 배재할 수 없음을 확인하였다. 이를 확인하기 위한 저해상도 분광관측이 진행되고 있으며, 이의 예비분석 결과를 아울러 발표할 예정이다.

In relation to shortening generation by using embryo culture of barley immature seed, it is important to find out profitable embryo age for embryo culture and to understand the relationship among embryo and other characters. Two varieties(Olbori and Dusan #12) were cultivated under two growth conditions(15/10 and 25/15$^{\circ}C$). The embryos were aseptically excised when immature seeds were collected 9, 13, 17, 21, 25 and 29 days after heading and cultured on $B_5$ medium. On the 21st day after heading, the length of embryos from top or middle part of spike was longer than that from bottom part. Embryos from bottom part under low temperature condition had the shortest length. Shoot length, root length and root number after embryo culture were little difference among three parts of spike under high temperature condition. Under low temperature, seedlings from bottom part of spike were inferior to those from top or middle part. Length of 29-day-old embryos under low temperature condition was similar to that of 17-day-old ones under high. Under high temperature condition, the length of 17-day-old embryo had positive correlation with kernel width, shoot length, root length and root number, but that of 21-day-old one didn't have. Seventeen-day-old embryos obtained from 25/15$^{\circ}C$ growth condition seem to be efficient to shortening generation by using embryo culture.

The melanocortin-4 receptor(MC4R) is virtually expressed in all brain regions and plays an important role in energy homeostasis in mammals. MC4R has been intensively studied as a trait gene controlling economically important traits, such as growth and feed conversion, etc. Six hundreds and sixty Duroc pigs were genotyped for the MC4R locus and analyzed their relationships with breeding values for average daily gain(ADG), backfat thickness(BF), days to 90kg(D90) and feed conversion(FC). The estimated genotype frequencies for the all Duroc pigs were: 30.8%, 45.2%, 24.1% for AA, AB and BB genotypes, respectively. The mutant A allele was significantly associated with ADG, D90 and BF whereas no significant relationship was found with FC. The change of gene frequencies by generation was shown in both selected and culled groups. These results indicate that the MC4R polymorphism could be integrated in the present selection program to realize a marker-assisted selection for the growth traits of the Duroc population.

The research investigates the attitudes toward children among mothers young children and maternal grandmothers, focusing specifically on the ideal number of children, gender preference, old age security and positive and negative values of children. A total of 442 respondents, consisting of 221 young mothers (average age of 35) and 221 maternal grandmothers (average age of 63) completed a questionnaire developed by Kim, Park and Kwon (2005). The reliability of the scales ranged from Cronbach α of .78 to .91. The results are as follows. First, as for the ideal number of children, young mothers reported that they would prefer two children, while grandmothers reported that they would prefer four children. As for the ideal number of male child, young mothers reported that they would prefer that they would prefer one son, while grandmothers reported two sons. Second, as for the gender of the child, young mothers did not show a gender preference, while grandmothers stated that at least one child should be a son, especially if it is the only child. Third, grandmothers had higher expectation of old age security in their male child than young mothers but two groups did not show any difference for the female child. Fourth, as for positive values of children, young mothers were more likely to emphasize personal aspects (i.e., psychological pleasure and happiness) and family cohesiveness, while grandmothers were more likely to emphasize social aspects (i.e., continuing the family line and old age security. As for negative values of children, young mothers were more likely to emphasize personal aspects (i.e., parental role and responsibility), while grandmothers were more likely to emphasize social aspects (i.e., family conflict and relationship). Fifth, as for factors that influenced the number of children that they decided to have, young mothers were more likely to report negative values of children (i.e., financial constraints), while grandmothers were more likely to emphasize positive values of children (i.e., continuing the family line).

The purpose of this study is to examine factors influencing quality of life for individuals in the family, school or workplace, leisure settings, and Korean society using the indigenous psychological analysis. A total of 3,406 participants, consisting of 1,331 elementary, middle, high school students and 2,075 parents and teacher, completed an open-ended questionnaire developed by Kim and Park (2004b). The respondents reported the factors that influence quality of life in Korean society as follows: Economic condition, collective effort, leisure and cultural life, harmonious interpersonal relationships, effective government policy, and educational attainment. The factors that reduce quality of life in Korean society are as follows: Economic uncertainty, political instability, lack of citizenry, ingroup favoritism, corruption, lack of facilities for leisure and social life, and overemphasis on educational achievement. Second, the factors that influence quality of life in the family are as follows: Harmonious family relations and financial security. For students relationship with friends and academic achievement are reported as important factors influencing quality of life at school. For adults, harmonious interpersonal relationship, financial factors and occupational achievement are reported as important factors influencing quality of life at the workplace. For leisure and social leisure life, financial security, leisure time and interpersonal relationships are reported as important factors influencing quality of life. Third, as for generational differences, students reported political instability and adults reported economic uncertainty as the most important factor reducing quality of life in Korean society. For family life, students reported conflicts among family members and adults reported financial constraints as the most important factor reducing quality of life. For leisure and social life, students reported lack of leisure time and adults reported financial constraints as the most important factor reducing quality of life. Fourth, for students the following characteristics were associated with higher quality of life: Higher socio-economic status of the family, younger, and higher academic achievement. For adults, the following characteristics were associated with higher quality of life: Higher socio-economic status of the family and greater achievement their social life. Implications of these results on the quality of life in Korea, focusing on human relationship, financial factors, self-regulation and educational achievement are discussed.

To investigate the dining habits in relation to Kimchi for the Koreans in Commonwealth of Independent States(CIS), a survey was conducted to 199 Koreans living in Moscow, Sahalin, Uzbekistan, and Kazakstan. Most of the respondents answered that thor keep the Korean food lifestyle, and especially the old age group and Koreans in Sahalin showed higher ratio for Korean food lifestyle. In the Kimchi preference and Kimchi consumption, 85.9% of the respondents like Kimchi because Kimchi is our traditional food and its taste is good, and 95% of them consumed Kimchi once or more everyday. In the kinds of Kimchi, 99% of the respondents had experiences in eating or seeing Chinese cabbage Kimchi, 91.5% cucumber Kimchi, 88.4% cabbage Kimchi, 82.4% white water Kimchi, 75.4% sikhae, respectively, while the frequencies of kakdugi, chonggak Kimchi, and leek Kimchi were relatively low. In connection with the utilization of Kimchi, many respondents answered that Kimchi is sometimes used in cooking of Kimchi cchigae or Kimchi bokkum. Most of Russians like Kimchi in spite of the hot taste and it shows the possibility that Kimchi can be spread throughout foreign countries.

The inheritance and varietal differences of resistance to bacterial leaf blight caused by Xanthomonas oryzae in rice were studied. Among eighteen cultivars used, 'IR2061-465-1-5-5', 'IR2061-552-6-9', 'IR 1561-228-9-3', ana 'Milyang42, were found to have a high level of resistance to the three isolates of X. oryzae at maximum tillering and flowering stage. Varietal differences in lesion development of the cultivars belonging to the same varietal group were clearly recognized. For the genetic study on bacterial leaf blight resistance, two rice breeding lines 'IR2061-465-1-5-5', 'IR1561-228-3-3' were crossed with susceptible cultivar 'Milyang 23'. The $F_1,F_2,\;and\;F_3$ progenies were evaluated at flowering stage using the bacterial isolate 'JN 7853'(II). Average lesion length of the $F_1$ plants of the crosses showed longer than that of resistant parents, and the frequency distribution of lesion length in the $F_2\;and\;F_3$ populations showed continuous variation.

The main purpose of this research is to investigate the qualitative nature of Korean adolescents and their parent's perception of elderly parents care. In addition, this research exams the quantitative differences between the two generations in term of their elderly parents care self-efficacy and attitude towards caring for their elderly parents. Further, an examination of the parental influence upon their children's elderly parents care self-efficacy and attitude towards caring for their elderly parents. There were 2,460 participants in this study, with 820 adolescents, and 820 fathers and 820 mothers. The results of the study were as follows: First, in terms the participants perceptions of "the most difficult aspect of caring for elderly parents", the most representative response for adolescents was financial difficulties, while for parents differences in opinions. When it came to "the best aspect of caring for elderly parents" the most representative response for adolescents was harmonious family, while for parents good for children's upbringing. When it came to "actual acts (behavior) of elderly parents care" the most representative response for adolescents was living together with their elderly parents, while for parents looking after their elderly parents. When it came to "the best method of caring for their elderly parents" the most representative response for both adolescents and parents was providing a peace-of-mind for their elderly parents, followed by the second most frequent response of adolescents living together with their elderly parents, and for parents talking with their elderly parents. When it came to "how one feels when not caring for their elderly parents" the most representative response for both groups was a feeling of indebtedness. Second, for the quantitative analyses of the differences between the two generations, the parents showed a lower level of elderly parents care self-efficacy and a higher level of negative attitude towards caring for their elderly parents, when compared to the adolescents. Third, for the parental influence upon the adolescents' elderly parents care self-efficacy and attitude towards caring for their elderly parents, the only significant influence found was the mothers' elderly parents care self-efficacy.

In the respect of automobile history, the tendency to the development of automobiles for the latest 100 years has been leaded by technical performances. Especially, with the rapid growth of the newest electronic industry, the technical know-hows of automobiles improved in short terms have brought about outstanding results. The differences of the technical know-hows are little between some of the famous automobile manufacturing industries and the rising. So, now, the automobile design became a basis in selecting a car. The latest tendency to automobile style in accordance with the improvement of a universal life quality has been changed to a characteristic design meeting various needs of customers. RV, UV, MPV(and so forth ) meeting their needs made an appearance, or a characteristic model derived from them respectively appeared. We tried to study a new mini SUV-typed-concepcar design with a touch of the next concept. The whole design process from our researches to the end hard model was performed at the Design Center, Daewoo Automobile, based on the automobile design processes. Especially, We styled an automobile concept as inexpensive, characteristic, new one to have a car easily at the young and made an analysis of customers' responses for referring to this study in generating the next SUV-typed-automobile.
