This study identifies the relationship by each element of a unique culture which aerobic gymnastics national team has generated, and analyses it in terms of quality. This study also seeks to understand, their lives, cultures and identities through in-depth exploration, participation, observation and analysis of aerobic gymnastics national Team players’ particular sub-culture life. This study has used ethnographic research methods, the participants of the study are the seven national tearn players currently playing a game and the data have been collected through in-depth interviews, participation and observation. The results are as follows: First, the entry into the aerobic gymnastics world: to grow as a player. The study participants’ motivation to start the aerobic gymnastics is related with the advice of their parents or friends, their interest or college admission. Second, to view from the socio-cultural perspective of aerobic gymnastics national team player. There were the elements of a group culture, a religion culture, and an alienation culture. Third, to view from the socio-cultural perspective of aerobic gymnastics national team player. There were the elements of the lack of the infrastructure, the indifference of the sports organizations, the truth and the falsity of the title of the national player.

The objective of this study is to have an in-depth understanding of the exercise experience course of national aerobic gymnastics athletes. To achieve this objective, this study used the grounded theory, a quality research methodology. With this research methodology frame, five active national aerobic gymnastics athletes were selected as research subjects. Data were collected through the in-depth interview and participatory observation with them. For data analysis, the coding paradigm were constructed to elicit the concept according to the analytical method of the grounded theory presented by Strauss & Corbin(1990) and identify the relationship between concepts. As a result, the following findings were obtained. First, 107 concepts, 15 subcategories and 9 superordinate categories were elicited from the open coding. Second, As a result, the following matters were found: ‘difficulty of life as athlete’ as the causal situation; ‘slump’ as the contextual situation; ‘worry about life as unpopular aerobic national gymnastics’ as the central phenomenon; ‘positive environment and negative environment’ as a conciliatory situation; ‘reality conquest and lamentation’ as the strategy of action/interaction; ‘building up of the sense of pride as athlete and building up of the sense of loss as athlete’ as result; and the like. Third, the ‘to surmount about difficulty as unpopular national athlete’ was elicited as the core category by choice coding.

목적: 인간 제대혈로부터 간엽성 섬유세포양 세포를 분리, 배양함으로써 제대혈 내의 순환성 간엽줄기세포의 존재여부를 확인하고, 이의 연골세포 분화능을 증명하고자 하였다. 대상 및 방법: 총 50 유니트의 제대혈로부터 분리된 유착성 세포군의 세포형태 및 면역표현형을 분석하였다. BMP-6을 첨가하였거나 또는 첨가하지 않은 연골분화배양액을 이용하여 펠렛 배양의 형태로 연골분화를 유도 배양하였다. 연골세포로의 분화를 관찰하기 위해 역전사 중합효소연쇄반응을 수행하였으며, Safranin-O 염색과 제2형 콜라겐에 관한 면역염색을 시행하였다. 결과: 제대혈 단핵세포로부터 균질성의 섬유세포양 형태의 유착성 세포군이 배양되었다. 이 세포군은 간엽줄기세포 관련 항원 양성, 조혈모세포항원 음성, 조직적합항원 음성, 내피세포 및 파골세포 관련 항원 음성이었다. 연골분화 펠렛 배양 시 BMP-6을 첨가한 군에서 펠렛의 크기 및 연골세포관련 인자의 발현이 증가하였고, Safranin-O 염색과 제2형 콜라겐의 면역염색도 강양성이었다. 결론: 제대혈 내에 순환성 비조혈성 연골형성 간엽줄기세포가 존재함을 확인하였고, 연골분화 배지에 BMP-6을 첨가함으로써 제대혈 유래 비조혈성 간엽줄기세포의 시험관 내 연골분화의 효율을 향상시킬 수 있었다. Purpose: The aim of this study was to demonstrate the existence of circulating mesenchymal stem cells (MSC) in the human umbilical cord blood (hUCB) and to evaluate the chondrogenic differentiation potential of hUCB-derived MSC in vitro. Materials and Methods: Fifty hUCB harvests were cultured in media supplemented with 10% fetal bovine serum. The adherent fibroblast-like cells were characterized by immunophenotyping and induced to differentiate into chondrocytes in the pellet culture with and without BMP-6. This study performed RTPCR of the chondrogenic markers, Safranin-O stain and type Ⅱ collagen immunohistochemical stain. Results: The mononuclear cells isolated from hUCB formed adherent colonies with an attached well-spread fibroblast-like morphology. The cells positively expressed the MSC-related antigens, but did not express the hematopoietic, HLA-DR, endothelial, or osteoclast antigens and could be induced to differentiate into chondrocytes under proper stimulation. BMP-6 increased the size of the pellet and the mRNA levels for aggrecan, type Ⅱ collagen and type Ⅸ collagen and enhanced the levels of proteoglycan synthesis during chondrogenic differentiation. Conclusion: The homogenous fibroblast-like cells developed in cultures from hUCB with chondrogenic differentiation potential were considered to be MSC. Furthermore, it was found that BMP-6 enhanced chondrogenic differentiation of the hUCB-derived MSC in the pellet culture.

The object of this study is meaningful for the national aerobic gymnastic players in the review of de-socialization process by retirement and re-socialization process experiencing in the adaptation process for the 2nd vocation through surveying, describing, and analyzing the retirement process and social adaption process of them. The results deduced out of such research process are as follows. First, the motive for the national players starting the workout in the initial stage getting into the aerobic gymnastic world has appeared to be the suggestion of acquaintances, own interest, or purpose to enter the university. Second, the reasons of retiring from the national aerobic gymnastic players, in the stepdown stage from the top, have appeared compositively with various factors of injury, military service, etc. For the national aerobic gymnastic players, third, it has shown that some players had prepared preliminarily for entering the new world, but there are other players who had not at all prepared for the new profession in the vocation preparing process after retirement.

This study has been intended to find out the flow of immersion arising from the environmental factors and situational factors related to the exterior experiences as well as to know the new information for the mystery and questions regarding the internal experiences of the immersion into workout that is experienced in the process of training and games by grasping how the factors of workout immersing factors, that can be a much meaningful and valuable experience to the national aerobic gymnastic players’ are influencing to the aerobic gymnastic process. The analysis results have been deduced out as follow. First, the substantial characteristics of immersion experience can be categorized into "experiencing time", "experiencing space" and "experiencing body". Second, the structural factors and flow types of the immersion can be categorized into "concentration into the motions", "harmony of ambient environment and player", "expression of pleasure and freedom". Third, the factors related to the success or failure of immersion can be categorized into "self-confidence and own unique training method" and "excessive concentration and mistake".
