  • This study was carried out to find growth characters and distribution of above and underground in natural crossed population of Paeonia lactiflora Pallas. Sprouting time was 1 April to 15 April, and distribution of stem length ranged from 21 to 80cm, and 3 to 18 in stem number. Distribution of root length ranged from 12 to 59cm, root number per plant was 73 to 4, root yield per plant was highly varied by 37 to 882g, and larger root above 750g was occupied by 7.1%. Paeoniflorin content was 1.9 to 10.29% and plants containing higher paeoniflorin was 14.3%. Root length and yield had highly positive correlation. Root diameter and stem length was also positively correlated.

  • The purpose of this study is to investigate whether there are differences in adolescents' school adaptation according to the types of perceived parental attitudes and consistency. For this purpose, 586(306 girls) middle and high school students were surveyed about their perceived parental attitudes and school adjustment, and the differences were verified through multivariate analysis of variance (MANOVA). The results showed that the adolescents' school adaptation was different according to the types of parental attitudes. Affection - autonomy cohort group's school adjustment was significantly higher than the other groups. In addition, the hostility - control group were found to have lower adaptation level than the disagreement group. Based on this results, we discussed the importance and influences of parental attitude and suggested the directions of follow up studies on parenting attitude and adaptation.

  • The main purpose of this paper is to find out the characteristics of foreign tourists comparing to Korean and how they evaluate the festival respectively. Data were collected during the 57th Baekje cultural tourism festival. The total of 674 sample sizes was collected during the festival, of which 558 respondents were domestic visitors, and 116 were foreign visitors. The empirical results showed that domestic visitors and foreign visitors are different in terms of the perception of performance evaluation, and satisfaction. Especially foreigners' degrees of satisfaction proved to be higher than those of koreans. It also expects the result of the study contribute to the development of efficient festival management policies and programs and facilities to meet the goals of cultural tourism festivals. Besides, the outcome of this research may be useful to other festivals and their future operation.

  • The purpose of this study was to identify the quantitative trait loci (QTL) associated with gel consistency (GC), and to evaluate the relationships between GC and physico-chemical properties related to eating quality in rice. A total of 120 doubled haploid (DH) lines derived from a cross between 'Samgang' and 'Nagdong' and 26 varieties were used for this study. The 120 DH lines were divided into four groups, soft (61~100 mm), medium (41~60 mm), hard (26~40 mm) and whole population, according to the gel length. A negative correlation between GC and amylose content was observed only in the soft group. The GC negatively correlated with lipid content in the medium, and the whole population, but positively correlated with lipid content in the soft group. The positive correlation between GC and protein content was observed in the soft group, while negative correlations were observed in the medium group and the whole population. Two significant QTLs regarding GC were detected on chromosomes 4 and 11. They collectively explained 23% of phenotypic variation with LOD score of 3.1 and 2.9, respectively. The DNA markers of S4026 and RM287 were tightly linked to GC in the DH population and 26 varieties, respectively.
