This study aims to understand the reasons why the elderly become interested in and engage in dance as a leisure activity and give up the activity early. It will also explore methods that will attract and continually engage the elderly (60 and above) in dance classes for a long-term period. The participants of the study are all 60 years old and above who have voluntarily enrolled in dance classes. The dance classes are 50 minutes per class, twice a week. Most participants of this study drop out at the one years point. This study participants were selected using reputable case selective inductive category analysis which is widely used in the qualitative field of research. As such, the study is based on reputable case selection. The results are as follows: One reason that the elderly in the research chose to join a dance class was to enhance their health in their post 60’s while not being perceived as the “old generation” by the younger generations. A common excuse given to the younger generation for their participation is that they did not have the opportunity to engage in activities such as dance, at a young age and wanted to take advantage of their new found freedom. Another common reason given for participation in dance classes was the “fun factor.” The “fun factor” includes their interest in music in general, being able to participate in the dance activity with a partner, and the various genres of dance that they were exposed to. Finally, the research explored many reasons that the stress factors their class at the half way point. These reasons include the difficulty in learning musical terminology, the inability of the dance teacher to keep the participants’ interest, and the inability of the participants to keep up with the fast pace of the class. The Study The proposed study aims to further explore the motives for the participation of the elderly in dance activities as well as the reasons why the elderly choose to give up dance. The data collected will be useful for community leaders who wish to engage the elderly in long term dance classes. This is particularly important as the number of elderly is greater than ever before.

Expression of four biologic markers known as p53, proliferating cell nuclear antigen(PCNA), c-myc, and epidermal growth factor receptor(EGFR), was studied immunohistochemically in 121 cases of cervical tissues, which included 15 cases of normal cervical tissues, 50 cases of squamous intraepithelial lesions(SIL), and 56 cases of invasive carcinomas. This study was designed to elucidate the roles of these factors in the genesis and progression of cervical neoplasia and to identify their association with clinical parameters such as cell type, tumor size, lymph node involvement, squamous cell carcinoma(SCC) antigen level, and prognosis. In additon, this study evaluates the differences of coexpression rates in normal cervical tissues, SILs, and invasive carcinomas. (1) The intensities of p53, c-myc, and EGFR expression and the rates of PCNA, c-myc, and EGFR expression in cervical SILs and invasive carcinomas were significantly higher than those in normal tissues (p<0.05 and p<0.01). But there were no significant differences between SILs and invasive carcinomas in both of intensities and rates of p53, PCNA, c-myc, and EGFR expression. (2) The intensities and rates of p53, PCNA, and c-myc expression in the invasive carcinomas did not correlate with clinical parameters including cell types, tumor sizes, lymph node involvements, see antigen, and prognosis. But only the intensity and rate of EGFR expression were significantly higher in cases with tumor size larger than 3 cm when it was compared with cases with tumor sizes smaller than 3 cm(p<0.01), in cases with lymph node involvement when it was compared with cases without lymph node involvement(p<0.05), and in cases with SCC antigen levels more than 2.5 ng/ml when it was compared with cases with SCC antigen levels less than 2.5 ng/ml(p<0.05). (3) C-myc immunoreactivity was significantly correlated with EGFR overexpression(p<0.01). (4) The rates of simultaneous expression of four factors were decreased significantly in normal tissues and significantly increased in invasive carcinomas(p<0.01). The coexpression rate of two factors or more was 6.7% in normal tissues, 62.7% in SILs, and 70.0% in invasive carcinomas and the simultaneous expression rate of three factors or more was none in normal tissues, 34.0% in SILs, and 47.5 % in invasive carcinomas. These results show that the immunohistochemical detection of p53, PCNA, c-myc, and EGFR expression will be useful in differentiating the normal tissues and cervical neoplasia. The results of simultaneous immunohistochemical detection of these four factor expression also suggest to contribute a better understanding of the genesis of cervical carcinoma and that coexpression of more factors indicate more aggressiveness in cervical neoplasia, and show that simultaneous detection of these factors can be used in the early detection of cervical neoplasia and to predict malignant transformation of cervical lesions.

분산형 데스크탑 그리드 환경에서 자가 조직하는 연산 오버레이 네트워크를 통한 자가 스케줄링 기법

김홍수 ( Hong-soo Kim ),길준민 ( Joon-min Gil ),박학수 ( Hark-soo Park ),유기성 ( Ki-sung Yoo ),황종선 ( Chong-sun Hwang ) 한국정보처리학회 2006 한국정보처리학회 학술대회논문집 Vol.13 No.2

본 논문에서는 분산형 데스크탑 그리드 시스템에서 안정적이고 고 성능을 지원하기 위한 연산 환경 구성과 스케줄링 전략에 대해서 논한다. 데스크탑 그리드 시스템 환경은 자원제공자의 이질성(heterogeneous), 자원제공자의 휘발성 (volatility), 확장성(scalability), 연산 환경의 동적인 특성(dynamism)을 가지고 있다. 이러한 환경에서 자원제공자의 동적인 특성과 휘발성으로 인한 연산적 결함(Computational Failure)에 대처하기 위한 연산 환경 구성과 스케줄링 기법이 필요하다. 그러나 기존 분산형 연산 방식에서는 연산적 결함에 대해 안정적인 연산 환경을 보장하지 못하고 작업 처리량 감소나 전체 작업 처리 시간의 증가를 보인다. 따라서 본 논문에서는 이러한 문제를 해결하기 위하여 자원제공자 가용성 (Availability), 연산 지속성(Durability), 그리고 지역성(Locality)을 고려한 자가 조직적 연산적 오버레이 네트워크(SOCON: Self-Organizing Computational Overlay Network)를 구성하여 안정적인 연산 환경을 제공한다. 또한, 구성된 SOCON 을 기반으로 연산 에이전트를 통해 자원제공자의 동적인 특징을 반영하는 자율적 FCFS 기법 (A-FCFS: Autonomous First-Come First Serve)을 제안한다. 제안된 SOCON 기반 자율적 스케줄링 기법을 Korea@Home 에 적용하여 성능 평가를 보여준다.
