목적: 이 논문은 한국 청소년들의 외모 걱정이 언제 어떻게 형성되고 변화하는지를 추적하여 그것의 심각성 정도를 밝히고자 하였다. 방법: 한국청소년정책연구원이 공개한 다년간의 추적 조사 자료에 대한 이차분석이 시행되었다. 통계기법으로는 반복측정 ANOVA, 대응표본 t-검정 및 카이자승 검정이 적용되었다. 결과: 청소년들에 있어 외모에 대한 걱정은 초등학교 고학년에 시작되어 성장과 더불어 강화되다 중 2나 중 3을 지나면서 점차 약화되는 것으로 판단된다. 일부 학생들은 청소년 시기 내내 외모에 대해 걱정하는 것으로 나타났지만, 고등학교나 대학에 진학한 후에는 청소년들의 외모 걱정이 눈에 띄게 감소되었으며, 어느 시점에서 외모 걱정을 벗어난 청소년은 다시 외모 걱정에 빠질 가능성이 아주 적다는 사실도 발견되었다. 한편 외모 걱정에 성별 차이가 뚜렷이 나타났다. 평균적으로 여학생이 남학생보다 외모에 대해 더 걱정하며, 외모 걱정이 남학생보다 1-2년 정도 더 일찍 정점에 도달하였다. 결론: 청소년의 외모 걱정은 성장과 더불어 역동적으로 변화한다. 외모에 대해 심각하게 걱정하는 청소년들이 적지 않지만, 일반적으로 추정되는 것보다는 청소년들의 외모 걱정은 상당히 유동적이며 다수의 청소년들이 외모 걱정에서 자유롭다고 판단된다. Objectives: This paper examines how serious the appearance concerns of adolescents is in South Korean society by delving into the formation and changes of adolescents’ appearance concerns. Methods: We conducted a secondary analysis of the data of multi-year tracing surveys which the National Youth Policy Institute opened to the public. The repeated Measures ANOVA, the paired t-test, and a chi-squared test were applied against the data. Results: It was found that about one out of ten adolescents experienced concerns that began as early as the upper grades of elementary school, reached its peak in middle school, and decreased afterwards. On the other hand, some of them faced enduring appearance concerns and seemed to suffer from it. One interesting finding is that adolescents once relieved from the concerns were free from it permanently. We also found that there were considerable differences between male and female adolescents in terms of the level of concerns they experienced, their peak periods, and other characteristics. Conclusions: Appearance concerns changes dynamically according to development of adolescence. Appearance concerns was less prevalent among adolescents than predicted, and it seemed considerably fluid. Our study not only confirms but also challenges some important findings of previous studies.

Objectives: As the surgical techniques are developed such as adopting robotic surgery etc. It has been reduced postoperative side effects such as urinary incontinence and sexual dysfunction etc., but also remain constant risk of recurrence after the treatment. It is very important to figure out the predictive factors, whichincreasing the probability of long-term survival, by Analyzing the progression of the disease according to biochemical recurrence (BCR). This study aims to figure out the influential predictive factors on BCR by using Korean Prostate Cancer Registry (KPCR) database, which constructedwith providing data from Korean manifold, because of therecurrence-free survival rates are reported to vary according to geographical location and race. Methods: KPCR database consists 7,394 patients’ data which collected from six medical institutions, and final analysis was conducted with 5,119 patients’ data which collected from December 2003 to December 2014. Statistical analysis was conducted with the multivariable Cox proportional hazard regression models to figure out the correlation of clinical factors which affect BCR. The biochemical recurrence free survival rate (BCR-FS) was calculated using with Kaplan-Meier method. Results: The 5 year BCR occurred in 23.6% (1,209 patients). As a result of the recurrence rate, prostate specific antigen (PSA) value ≥20.1 ng/mL was 49.3%, the clinical T3 stage was 40.4%, Gleason score ≥8 was 54.4%, Gleason score 7 was 21.8%. The mean duration of BCR was 20.7 months and the strongest predictor of BCR was Gleason scoreand PSA value ≥20.1 ng/mL. Conclusions: It has been verified that, Gleason scores and PSA value are the most influential factors for biochemical recurrence after radical prostatectomy. These results will be helpful fordetermining the treatment direction in postoperative follow-up and able to contribute to improving survival outcome in the future.
