정진오 ( Jin Oh Jeong ) 한국스포츠심리학회 2008 한국스포츠심리학회지 Vol.19 No.3

이 연구의 목적은 운동행동변화를 예측하는 구성요인과 지각된 건강상태 간에 어떤 관계가 있는가를 알아보기 위해 2007년 서울 및 경기도에 거주하고 있는 당해연도 30세 이상의 성인 남녀 1400명을 편의표집하였다. 그리고 최종적으로 1247명을 분산분석과 로지스틱 회귀분석에 적용하였다. 분석된 결과에 의하면 첫째, 남자는 자극통제가 낮을수록 자신의 건강상태를 `아주 좋다`보다 `나쁘다` 또는 `그저 그렇다`라고 지각할 확률이 높은 것으로 나타났다. 둘째, 여자는 자아재평가를 낮게 지각하고 자극통제가 낮을수록 스스로의 건강상태를 `나쁘다`와 `그저 그렇다`라고 지각할 확률이 높은 것으로 나타났다. 셋째, 운동손실을 높게 지각하고 있는 남녀 모두 자신의 건강상태를 `아주 좋다`보다 `나쁘다`라고 지각할 확률이 높은 것으로 나타났다. 이러한 결과는 운동행동변화를 예측하는 구성요인과 지각된 건강상태 간의 관계와 관련하여 후속연구를 위해 논의하였다. The purpose of this study was to examine the relationship between self-perceived health status and construct estimated change of exercise behavior. The subjects of this study were a total of 1247 male and female Korean adult(over 30 years old) in Seoul and Gyeong-gi around were surveyed. The method of the statistical analysis used in this study, were One-way ANOVA, one-way MANOVA, and Multinominal logistic regression analysis. The result were as follows. First, there was a statistically significant differences according to sex on self-perceived health status. The male subjects showed higher in processes of behavioral(counter conditioning, help relationship, reinforcement management) on good health status, higher in decision balance(pros of exercise) on fair health status, and higher in self-efficacy on fair and good health status than female subjects. Second, for the men, negative affect processes of behavioral(reinforcement management, stimulus control), while positive affect decision balance(cons of exercise) were significant correlate of very bad, bad, and fair health status. For the women, negative affect processes of cognitive(self reevaluation) and processes of behavioral(stimulus control), while positive affect decision balance(cons of exercise) were significant correlate of very bad, bad, fair, and good health status. The model correctly classified 52.3% of the men subjects and 56.1% of women subjects. These results were discussed relate to the relationship between self-perceived health status and construct estimated change of exercise behavior.

The purpose of this study attempted to reinterpretation of the development history of the Korea`s DanceSpor t(1896-1945). Some previous literature reviews have presented uncritical acceptance and the front quotation on the development history of the Korea`s DanceSport. Such, at the time of the historical background with regarding to the history of Korea`s DanceSport was to establish a new perception through ``Korea`s DanceSport was to influx some terms and types, and how did popularization?``. Accordingly, the following result has been acquired by previous literature reviews: First, The Social Dance in the period of enlightenment, Emperor Gojong and a high-ranking government official were likely to have used as a means for communicating with the Western powers that the using in order to Japan to reject. Second, The advent of dance called Mudo(1909) is specially significant in the light that the foreign Western dance was introduced into Korea for the first time. Mudo penetrated rapidly into the general public as Kim Dong-han`s Art Academy and Lee Byeong-sam`s Gumi Dance Institute were established. Third, Social Dance had popular vogue, the current intellectuals bitterly argued each other on its positiveness and negativeness in 1920s. Social dance is meaningful in the light of its advent before the New Dance emerged, the initial introduction of foreign dance, and accepting actively the modernism of dancing with the feminism and the enlightenment. These results were discussed relate to reinterpretation of the development history of the Korea`s DanceSport(1896-1945).

Polycaprolactone(PCL)과 biphasic calcium phosphate(BCP)는 생체적합성 및 골 형성 촉진 등으로 인해 정형외과 소재로 사용되고 있다. 하지만, PCL은 표면이 소수성으로 인해 세포의 부착 및 증식에 제한적이기 때문에 이를 극복하기 위해 본 연구에서는 감마선을 이용하여 골 재생을 위한 친수성이 향상된 PCL/BCP 나노섬유를 제조하였다. 나노섬유는 전기방사를 통해 제작했으며, 감마선을 이용하여 acrylic acid(AAc)를 도입하였다. SEM을 통해 나노섬유 표면을 확인하였고, AAc가 도입된 나노섬유 위에서 MG63의 초기 생존율이 현저히 증가한 것을 확인하였다. 알칼리성 포스파테이즈 활성은 1.239±0.226 nmole/μg/min으로 개질되지 않은 나노섬유(0.590±0.286 nmole/μg/min) 보다 증가하였다. 따라서, AAc가 도입된 PCL/BCP 나노섬유는 골조직 재생에 활용될 수 있을 것으로 기대된다. Polycaprolactone (PCL) and biphasic calcium phosphate (BCP) have been considered as useful materials for orthopedic devices and osseous implants because of their biocompatibility and bone-forming activity. However, PCLbased scaffolds have hydrophobic surfaces reducing initial cell adhesion or proliferation. To overcome the limitation, we fabricated surface-modified PCL/BCP nanofibers using gamma-irradiation for bone tissue engineering. PCL/BCP nanofibers were prepared by electrospinning and then we supplemented hydrophilicity by introducing acrylic acid (AAc) through gamma-irradiation. We confirmed the surface of nanofibers by SEM, and then the initial viability of MG63 was significantly increased on the AAc grafted nanofibers, and alkaline phosphatase activity(1.239±0.226 nmole/μg/min) improved on the modified nanofibers than that on the non-modified nanofibers(0.590±0.286 nmole/μg/min). Therefore, AAc-grafted nanofibers may be a good tool for bone tissue engineering applications.
