The purpose of this study was to investigate the effect of selected internal and situational factors on children`s prosocial behaviors. While child`s sex and trait empathy were chosen as internal factors, state empathy and social evaluation were regarded as situational factors. The subjects were 72 bays and 72 girls chosen from 288 eleven-year-olds. This selection was based on their emplathic scores measured by the Bryant Empathy Scale (1982). Half of the 144 children belonged to the high-trait empathic group and the other half to the low-trait empathic group. Within each of the high-and the low-trait empathic groups, equal numbers of boys and girls were randomly assigned to one of the two state empathy conditions and two social evaluation conditions. The state empathy conditions were divided into the arousal condition and the disregarding condition. To control social evaluation, subjects were led to believe that the experimenter either would or would not evaluate their donation of colorful ball-point pens to handicapped children. The data was analyzed by 4-way ANOVA (sex(2)×trait empathy(2)×state empathy(2)×social evaluation(2)). The results were that (1) children`s prosocial behaviors were significantly different by sex, state empathy, and social evaluation, and (2) children`s prosocial behaviors were not significantly different by their trait empathy level.

본 연구는 지방대학생들이 국제결혼이라는 현상을 어떻게 인식하며, 다문화가족에 대해 어떠한 태도를 갖는지 포커스그룹면접을 통해 탐색하였다. 연구참여자들은 국제결혼을 애정으로 맺어진 연애결혼과 농어촌지역을 중심으로 이루어지는 중매결혼으로 구분하였다. 국제결혼의 주체가 자신인지 타인인지 따라 찬반 태도상에 차이를 보였는데, 여기에는 가족주의에 입각한 결혼관, 인종적 편견, 이중적 차별 등이 작용하였다. 한편, 국제결혼이 증가하리라고 예측하지만 앞으로의 다문화사회가 화합을 이룰지 갈등이 심화될지에 대해서는 상반된 의견을 보였다. 연구참여자들은 다문화사회로의 긍정적 이행을 위해 정부의 적극적 개입과 사회인식의 변화가 필요하다고 보았다. 본 연구는 국제결혼에 대한 대학생들의 인식과 태도를 담론화함으로써 다문화가족을 위한 사회복지적 함의를 시사하고자 하였다. The purpose of the present study was to explore how rural university students conceptualized international marriage and what attitudes they had towards multicultural families. There were 136 participants, who were between the ages of 20 to 24 years old. The focus group interviews were conducted to discuss international marriages in general, the possibility of the University student`s own international marriage, their parents` reactions to international marriages, and the future of multicultural families in Korea. Rural university students distinguished differences between arranged marriages and love marriages. They recognized the necessity of internationally arranged marriages for people who cannot find a spouse in Korea. In terms of their own international marriage, they revealed familism, racism, and prejudice. While participants anticipated international marriages would increase, some of them mentioned that multiculturalism might undermine national unity, hinder social integration, and cultural assimilation. All the participants suggested government intervention to international marriage practice, welfare support systems for multicultural families, and social education for multiculturalism.

목적: 저자들은 인간 제대혈(umbilical cord blood)에서 간엽 줄기 세포를 분리 및 확인할 수 있었고, 이들 세포군에 대하여 골, 연골 및 지방세포로의 분화가 가능하였기에 이를 보고하고자 한다. 대상 및 방법: 제대혈(n=411)로부터 단핵세포군을 원심분리 방법을 이용하여 분리한 후 배양하였으며, 5-8회 개대배양 시에 1,000배 이상의 증식을 보인 세포군에 대하여 간엽줄기세포 및 타 세포계열 표면항원 검사를 시행하였다. 분리된 간엽줄기 세포군에 대하여 골, 연골 및 지방세포로의 분화를 시도하였다. 결과: 총 411개의 제대혈 중 95개(23.1%)에서 첫 배양 시 간엽 줄기 세포양 세포군(MSC-like cell population)이 확인되었으며, 5-8회 개대배양 시 1,000배 이상의 증식을 보인 세포군은 9개(2.2%)였다. 이들 세포군은 기존에 알려진 모든 간엽줄기세포 표면항원검사에 양성, 타 세포계열 표면항원 검사에는 모두 음성이었다. 분리된 간엽 줄기 세포군은 골, 연골 및 지방세포로의 분화가 가능하였다. 결론: 본 연구의 결과는 인간 제대혈이 서로 다른 세포 계열로 분화할 수 있는 간엽줄기세포를 포함하고 있다는 사실을 지지하는 것으로 판단된다. 인간 제대혈은 상대적으로 많은 양의 간엽줄기세포를 비교적 용이하게 얻을 수 있다는 장점이 있는 세포 공급원이 될 수 있을 것으로 사료되며, 향후 조직 공학 및 세포 치료를 위한 세포 공급원의 하나가 될 수 있을 것으로 기대한다. Purpose: Human umbilical cord blood (hUCB) is well known for a good source of hematopoietic stem cells (HSCs). However, the presence of mesenchymal stem cells (MSCs) in hUCB is still not well approved by many authors. We hereby report the isolation and characterization of MSCs from hUCB, as well as their differentiation into osteogenic, chondrogenic and adipogenic lineages. Materials and Methods: Mononuclear cells were isolated from each hUCB harvest (n=411) by density gradient centrifugation, and suspended in -minimum essential medium supplemented with 10% fetal bovine serum (FBS). The cell population was expanded by successive sub-cultivation under the same condition. The cell population that showed more than 1,000-fold expansion at fifth to eighth passage was inspected with known surface antigens of MSCs and other cell lineage. The isolated MSCs were cultured in osteogenic, chondrogenic, and adipogenic condition to identify their potential to differentiate into different mesenchymal cell lineage. Results: Ninety five out of 411 hUCB units (23.1%) generated the MSC-like cell population during initial cultivation. Nine cell populations (2.2%) showed more than 1,000-fold expansion capacity at fifth to eighth passage. These cells positively expressed all known MSC-related antigens. They did not express any of myeloid, endothelial, or histo-compatibility antigens. All of the MSCs isolated showed the potential to differentiate into osteogenic, chondrogenic, and adipogenic lineages. Conclusion: Our study supports that hUCB does contain MSCs, which can be differentiated into different cell lineages. We believe hUCB will be a good source of MSCs with the advantage of availability and relative abundance. We think hUCB should not be considered as a medical waste, and it will serve as a good source of cells for tissue engineering and cellular therapy in the future.
