A new white spray-mum, 'White Ball' was bred by crossing between 'Stallion', a white anemone type flower, and 'Hyangno', an anemone type with pink petals in October 2003. The growth and flowering characteristics were investigated in forcing, natural, and retarding cultures from 2005 to 2007. The 'White Ball' was a medium-flowering fall-mum with white anemone type flower and had 16.2 flowers per stem, 3.6 cm diameter of flower in natural culture. The number of days to flowering and flowers per plant was 58.5 and 11.9, respectively, in forcing culture of 'White Ball' whereas the number of days to flowering was 54 in retarding culture.

A new cultivar of Rosa hybrida 'Loving Heart' was developed by crossing Gyeongkyo R-6 and 'Noblesse' at Gumi Floricultural Experiment Station in 2002. Characteristics trials were conducted three times from 2004 to 2007. This cultivar showed dark pink flower color (RHS, Red-purple group 66-B) and standard type with good flower shape. The flower diameter is 10.3cm and the number of petals per flower is 55. Vase life of 'Loving Heart' could be as long as 12.3days. The yield of 'Loving Heart' was $127stems/m^2/year$. 'Loving Heart' has good quality of cut flower and strong vigor in plant growth. This cultivar has straight stems and is easy to culture because of a few prickles on the top of stem. This cultivar is appropriate for both soil and solution(hydroponics) cultures.

This study was carried out to find morphological characters of flower and its distribution in mixed population of Paeonia lactiflora Pallas. In distribution of flowering periods, early, medium, and late matured type were 18%, 56%, and 26%, respectively. Flowering duration was less than eight days in 9% of flowers. In next 9 to 11 days, 12 to 14 days and more than 15 days showed, 50%, 37% and 4% respectively. For flower sizes, small size below 9cm diameter were 11%, medium size between 9 to 13cm diameter and large size above 13cm diameter were 65% and 24%, respectively. Among six kinds of flower colors - red, red pink, pink, light pink, pale yellow and white, pink color flowers was dominant, showed 56%. In flower types, single flower was 76%, and anemone, crown, bomb and japanese types were also present. Flower stem diameter were positively correlated with flowering duration, flower size and number of stamens, and negatively correlated with number of stamens and pistils, number of pistils and petals.

A new rose cultivar was developed from a cross between "Neon" and "Hello" by the rose breeding team of Gyeonggi-Do Agricultural Research and Extension Services in 1999. The cultivar, "Loving You" was finally selected in 2007 after evaluation trials for three years (2005-2007). The cultivar was developed for a standard-type cut flower with pink petals. "Loving You" grows vigorously and produces $108.5stems/m^2$ in a year, and has 50.2 petals per flower. The days to flower was 46 days, which is very short in rose. The length of cut flower was long with 76.8 cm. Vase-life of the cultivar could be as long as 11 days. The cultivar was applied for a variety protection in 2007.

This study analyzed the relationship between re-applications and the degree of re-applications under the assumption of a complex interaction between the location strategy and the internal capacity of a nursing home. The results of the study are as follows. First, although the relative influence on re-use is greater in hospital internal capacity (${\beta}=0.303$) than in hospital location strategy (${\beta}=0.313$) both factors have a statistically significant effect on the degree of re-use. Second, the importance of location strategy was found to be more important for rehabilitation-enhanced nursing hospitals than for general care (${\beta}=0.43$). It is suggested that detailed preparations should be made based on factors such as location marketability, traffic infrastructure, building sales, and medical concentration. Third, internal hospital capacity did not show any adjustment effects due to hospital type, and it was confirmed that both were important factors for general care and rehabilitation-enhanced hospitals.

This study had two aims (1) to explore the trajectory of family functioning (flexibility and cohesion) in the mothers' perspective and classify it according to the development of their child, and (2) to examine the differences in children's self-esteem as well the internal and external behavioral problems based on the latent groups. A total of 1,348 mothers and their children who participated in the survey in 2013 through to 2017 were analyzed. The group was subdivided into low incremental, average incremental, average-above incremental, and high unchanged groups according to the flexibility, and into low incremental, average incremental, decremental, high incremental, and above-high unchanged groups in terms of cohesion. From 2015 to 2017, the self-esteem of elementary school-age children showed differences depending on the flexibility and cohesion of family functioning; children in the high-unchanged group of flexibility and the above-high unchanged group of cohesion showed high self-esteem. Behavior problems of early childhood and elementary school-age children varied according to the latent classes of flexibility and the cohesion of family functioning. Children in low incremental and average incremental groups of flexibility and low incremental, average incremental, and decremental groups of cohesion showed more internal and external behavioral problems. These findings suggest that family functioning has significant effects on the psychological aspects of children.

The purpose of this study was to identify latent classes in changes of mothers' daily life stress over six years from multicultural families and to test its relationship with early adolescents' perceived neglecting parental attitudes and their academic achievements. For achieving this purpose, as the study sample 1,039 students were gathered from the 4th grade of elementary school to 3rd grade of middle school, using Growth Mixture Modeling, Multiple Group Analysis, and One-way ANOVA. The results were as follows. First, latent classes of mothers' daily life stress were categorized into three types: high-stable trajectory, moderate-changing trajectory, and low-changing trajectory. Second, these three types showed different characteristics in early adolescents' perceived neglecting parental attitudes and academic achievements. Third, early adolescents' perceived neglecting parental attitude were not significant determinants of the latent classes while academic achievements were. The findings of this study may provide a framework for understanding the relationships among mothers' daily life stress and early adolescents' perceived neglecting parental attitudes and their academic achievements in multicultural families and practical implications for providing social support to overcome daily life stress of mothers in multicultural families.
