Purpose: The object of this study is to develop a novel BMP-2 delivery system for continuous osteogenic differentiation and to induce osteogenesis of stem cells using a bi-phase alginate carrier in vitro. Methods: Alginate nanoparticle loaded BMP-2 was prepared by the reverse emulsification-diffusion technique. Physical properties and release profiles of alginate carriers were measured by Instron and ELISA kit, respectively. Cell viability and alkaline phosphate activity of hBMSCs differentiation was also evaluated by MTS and Metra BAP assays, respectively. Results: Optimal concentration for bi-phase alginate carrier was determined as 2 wt% by evaluating mechanical and biological properties, and differentiation of BMSCs for bone regeneration. The 2% bi-phase alginate carrier had the lowest initial and final release ratio. In addition, the 2% bi-phase alginate carrier had a little higher ALP activity than the homogeneous carrier. An improved controlled release profile was obtained by combining alginate hydrogel with lyophilized particles. Conclusion: Bi-phase alginate carrier has many advantages such as biocompatibility and controlled release capability. It is expected to be effective as a scaffold and carrier in bone tissue engineering.

This study is about the periodic characteristics of Wonsam in the Joseon Dynasty. Wonsam include the Danryeong-shaped Wonsam in the beginning, the compound Wonsam in a period of transition and the stereotyped Wonsam in the late Joseon Dynasty. The formative characteristics of Wonsam are divided into four stages. The first stage of the Wonsam is from the 15th to 16th century. The shape of Wonsam began to form and it was similar to one of Danryeong during this time. The formative characteristics of the first Wonsam included collars that looked like one of Danryeong, side pleats(called Moo) with multiple inner folds, straight cylinder-shaped sleeves, and a belt tied with the Wonsam. There were various fabrics that were used for the Wonsam from this stage. Second stage of the Wonsam is from the early 17th to mid 17th century. This period marked the beginning of the transition of the Wonsam and it served as a stepping-stone to the development stage in the Joseon Dynasty. The characteristics of the transitional Wonsam were a complex combination of the Danryeong and Wonsam. During this period, the Wonsam went through many changes and forms in a short period of time. Third stage of the Wonsam is from the mid 17th to early 19th century. The Wonsam was developed at this stage. The developed Wonsam went through a period of transition equipped with a stable form. The formative characteristics of Wonsam during this period included collars that faced each other, big and wide sleeves with multicolored stripes, Hansam, curve-edged side seam and the side pleats(Moo) with multiple inner folds had disappeared. It was a turning point from the single-layered clothes to double layered clothes and from dark blue to green color appeared at this time. The fabric patterns of this stage tended to consist of more simplified silk pattern. The fourth stage of the Wonsam is from the late 19th to 20th century. The Wonsam was expanded at this stage. The formative characteristics and fabrics were typically used for the standard Wonsam and were divided into two types; as a ceremonial robe used in courts and a wedding ceremonial robe for the common people. Phenomena such as sewing of double-layered clothes as one and straight-edged side seam during the late Joseon period developed into simpler and more practical fashion culture.

The purpose of this study was to examine the effect of the father`s participation in child rearing, the parental characteristics, the mother`s emotional characteristics on the mother`s parenting characteristics. The data of this study were from 2078 infants who were born in 2008 and their mothers who participated in the 1st Korean Children Panel Survey of Child-Care Policy Research Institute. The data collected were processed statistically by the structural model and the fit of the model was very good. The findings showed that the father`s participation in parenting had an positive effect on the mother`s parenting characteristics but the result was adverse with the mediation of the mother`s emotional characteristics. The direct effect of the parental characteristics was positive. However, the effect of the parental characteristics was found to be very negative when the mother`s emotional characteristics were used as mediators.
