The purpose of this study is to compare voice characteristics and voice-related quality of life (K-VRQOL) of the elderly female choir members using perceptual-auditory voice quality evaluation (GRBAS) and K-VRQOL scales. The participants were 77 women over 60 years old who were actively engaged in the choir in either Seoul or Busan. There are two kinds of choirs that indicate different engagement levels: regular choir and church choir. The perceptual-auditory vocal quality evaluation was listened to by / a / vowels and were graded by experts using the GRBAS scale. As a result, when comparing the differences between groups, the elderly female participants of the regular choir showed higher satisfaction in speech using the subjective speech recognition level than the elderly female members who performed in the church choir. In addition, the analysis showed that the satisfaction level was high in the physical function area of the K-VRQOL scale. This study confirmed that choral activities could yield positive results not only in terms of improving voice function in old age, but also to improve the subjective perception level of voice use, thus suggesting the necessity of systematic music programs to improve voices that are aging.

Objective : This study aimed to categorize the lifestyles of older adults into two types - healthy and unhealthy, and use machine learning to identify the personal values that influence these lifestyles. Methods : This cross-sectional study targeting middle-aged and older adults (55 years and above) living in local communities in South Korea. Data were collected from 300 participants through online surveys. Lifestyle types were dichotomized by the Yonsei Lifestyle Profile (YLP)-Active, Balanced, Connected, and Diverse (ABCD) responses using latent profile analysis. Personal value information was collected using YLP-Values (YLP-V) and analyzed using machine learning to identify the relative importance of personal values on lifestyle types. Results : The lifestyle of older adults was categorized into healthy (48.87%) and unhealthy (51.13%). These two types showed the most significant difference in social relationship characteristics. Among the machine learning models used in this study, the support vector machine showed the highest classification performance, achieving 96% accuracy and 95% area under the receiver operating characteristic (ROC) curve. The model indicated that individuals who prioritized a healthy diet, sought health information, and engaged in hobbies or cultural activities were more likely to have a healthy lifestyle. Conclusion : This study suggests the need to encourage the expansion of social networks among older adults. Furthermore, it highlights the necessity to comprehensively intervene in individuals' perceptions and values that primarily influence lifestyle adherence.

The characteristic of the beta wave among the EEG waves corresponds to the stress area of human perception. The over-bandwidth of the stress is extracted by analyzing the beta-wave correlation between the low-bandwidth and high-bandwidth. We present a KMeans clustering analysis model for unsupervised machine learning to construct an analytical model for analyzing and extracting the beta-wave correlation. The proposed model classifies the beta wave region into clusters of similar regions and identifies anomalous waveforms in the corresponding clustering category. The abnormal group of waveform clusters and the normal category leaving region are discriminated from the stress risk group. Using this model, it is possible to discriminate the degree of stress of the cognitive state through the EEG waveform, and it is possible to manage and apply the cognitive state of the individual.

오늘날 경제 성장의 발전은 현대인의 삶의 여유를 가져오게 되었으며, 그 중 뷰티산업의 발전은 국가 주력의 산업으로 발전하게 되었다. 이에 뷰티산업의 구성원인 여성의 사회진출의 기회가 증가 되었고, 이로 인해 여성들은 사회 적응을 위한 하나의 방법으로 외모적인 경쟁력을 가져야 했다. 외모에 대한 관심은 물론 매스미디어의 증가, 사회적, 문화적 분위기, 미용기술의 발달 등을 들 수 있다. 외모의 사전적의미로는 겉으로 나타나는 모습으로 외모관리를 위한 영역으로 피부 관리를 꼽을 수 있다. 피부 관리는 미에 관한 현대 여성의 관심의 증가로, 시간과 비용을 투자하여 외적으로 보여주는 관리로서 외모관리의 대표적 부분으로 중요시 되어오고 있다. 피부의 건강관리는 인식도 중요하고 실천도 중요하다. 그러나 인식과 실천의 관계를 구체적으로 연구한 논문은 부족한 실정이다. 특히 성인여성들을 대상으로 건강관리 인식과 실천을 연구하여 피부건강 관리에 대한 올바른 방안을 제시해준 논문이 필요하다고 생각하여 본 연구자는 이 논문을 설계하게 되었다. 본 연구의 조사대상은 서울지역에 거주하는 20세 이상 60세 미만의 신 성인여성을 대상으로 2017년 5월 02일부터 7월 30일까지 2달 동안 설문조사를 실시하였다. 모집단은 서울지역에 사는 성인 여성을 대상으로 총 400부의 설문지를 배포하였다. 그 중 응답이 불량한 사람 49부를 제외되고 351부가 최종 자료로 사용하였다. 연구 결과는 다음과 같다. 첫째, 조사대상자의 인구통계학적 특성을 알아본 결과, 연령은 '21-30세'가 85.2%로 가장 많았고, 결혼 상태는 '미혼'이 89.5%, 직업은 '학생' 67.0%, 최종학력은 '대학교 재학/졸업'이 68.1%, '가계의 월 소득은 '200만원 미만'이 71.8%로 가장 많이 소비되는 것으로 나타났다. 이상은 이혜원 (2009)의 논문과 같이 연령이 낮을수록 피부인식이 높아지며, 이들은 잠정고객으로서 피부 건강에 대한 비용을 높게 지불한다는 결과와 유사하다. 피부 관리실의 특성은 다음과 같다. 피부유형은 '복합성'이 47.6%, 적정 피부 관리 횟수는 '주 2회'가 32.5%, 적정 1회 피부 관리 비용으로는 '5만 원 이하'가 가장 많았으며, 피부 관리의 목적으로는 '여드름관리'가 32.8%, 피부 관리에서 중요하게 인식하는 부분으로는 '생활습관'이 79.8%로 대부분이었고, 피부의 유해요인으로는 '스트레스' 42.7%로 가장 높게 나타났다. 이상은 유유정(2013), 장은영(2013)와 같이 생활습관과 스트레스가 피부 관리에 영향을 준다는 결과와 유사하다.

In order to investigate the factors influencing QOL and life satisfaction of the physically disabled, the author interviewed, by using structuralized questionnaire, 440 individuals among the physically disabled who were participated in Health Examination from April to July, 1997. The questionnaire consisted of the general characteristics(sex, age, marital status, family number, etc), the Reintegration to Normal Living Index(RNLI) to assess QOL, and the single item of five-likert scale to evaluate life satifaction. The means of RNLI were $16.2{\pm}4.8$ in total score, $12.2{\pm}3.4$ in daily functioning and $4.0{\pm}2.1$ in perception of self. The respondents were less reintegrated toward social activities and relationships than impairments or disabilities. While the satisfied group was 47.3%, the dissatisfied group was 52.7%. As the results of multiple regression and logistic regression analysis, the significant predictors of QOL were age, education, job, grade of disability and subjective health status. The life satisfaction were related to economic status, job and subjective health status. To improve QOL and life satisfaction of the physically disabled, it is important that we improve their basic socioeconomic status by getting a job through rehabilitation education and induce them to have positive self-assessment by extending the opportunity of social participation.

Purpose : The purpose of the present study was to analyze and evaluate prior studies published in Korea on the cancer-related quality of life, in order to make recommendations for further research. Materials and Methods : A total of 31 studies were selected from three different databases. The selected studies were analyzed according to 11 criteria, such as site of cancer, domain, independent variable, research design, self/proxy rating, single/battery instrument, translation/back translation, reliability, validity, scoring, and findings. Results : Of the 31 studies, approximately half of them were conducted using a mixed cancer group of patients. Many of the studies asserted that the concept of quality of life had a multidimensional attribute. Approximately 30% were longitudinal design studies giving information about the changes in quality of life. In all studies, except one, patients directly rated their level of quality of life. With respect to the questionnaires used for measuring the quality of life, most studies did not consider whether or not their reliability and validity had been established. In addition, when using questionnaires developed in other languages, no studies employed a translation/ back-translation technique. All studies used sum or total scoring methods when calculating the level of quality of life. The types of variables tested for their influence on qualify of life were quite limited. Conclusion : It is recommended that longitudinal design studies be peformed, using methods of data collection whose validity and reliability has been confirmed, and that studies be conducted to identify new variables having an influence on the quality of life.
