Objectives: This study investigated the effectiveness of Dong's acupuncture for pain associated with a varicocele. Methods: A 23-year-old male patient visited for pain due to varicocele that occurred on March 2 and was treated with acupuncture and moxibustion three times on March 16, 17, and 19. The Numerical Rating Scale (NRS) was used to evaluate the patient's pain. Results: After the three treatments, the NRS scores decreased, and the patient's subjective symptoms improved. Also, the patient required no medication for a week from the date of treatment start. Conclusions: These findings demonstrate that Korean medicine may be an option for treating a painful varicocele, but further research is required for confirmation.

As a result, there were the pros and cons about the programs. Based on this, we propose a better method to increase the satisfaction of user experience for children. This study is significant in activating digital technology-based online education. This study expected to used as data on the user experience of a non-face-to-face online art education program in elementary schools in the future.

요양시설 노인을 위한 구강건강 평가 도구의 타당도와 신뢰도

김나연,배현숙,Kim, Na-Yeon,Bae, Hyun-Sook 대한치과위생학회한국치위생과학회 2021 대한치위생과학회지 Vol.4 No.1

Background: The elderly in long-term care facilities tend to have a diminished oral health status, with a high prevalence of dental caries and periodontal disease, as reduced cognitive function, joint mobility, and gait ability hinder the performance of oral hygiene. To improve the oral health of the elderly at long-term care facilities, it is necessary to have precise guidelines for oral health care and assessment; however, such guidelines are not readily available. Therefore, the present study aimed to develop an oral care assessment tool with verified reliability and validity. Methods: The participants in this study were 100 elderly patients at a care facilities and 10 clinical dental hygienists. Collected data were analyzed using the descriptive statistics, content validity index, and inter-rater reliability, as well as the analyses of intra-class correlation coefficient. Results: After a review of relevant literature, a preliminary questionnaire comprised of seven questions related to the evaluation of oral health was formed. After revising and supplementing the questions through a content validity test, a total of nine questions were selected. Conclusion: The novel assessment tool developed for the present study is anticipated to allow analyses of the level of problems related to oral health care before routine and professional care. Moreover, regular oral health status check-ups will enable the early diagnosis and treatment of diseases.

스마트 웨어러블 디바이스를 이용한 모바일 기반 사용자 피로도 측정 시스템 개발

김나연,김동근,Kim, Na Yeon,Kim, Dong Keun 한국정보통신학회 2017 한국정보통신학회논문지 Vol.21 No.12

최근 건강관리에 대한 관심이 높아지면서 건강상태를 모니터링 하기 위한 스마트 웨어러블 디바이스가 활용되어 오고 있다. 본 논문에서는 스마트 웨어러블 디바이스와 연동된 피로도 측정 시스템을 개발하였다. 충분히 휴식을 취하면 회복되는 신체적인 피로도와는 달리 정신적인 피로도는 일의 능률이나 집중력을 떨어트릴 수 있으므로 측정을 통해 정신 건강 상태를 모니터링 할 수 있다. 본 시스템은 스마트 웨어러블 디바이스에서 계측한 데이터를 스마트폰으로 전송하고 정신적인 피로도를 계산해주는 기능을 제공한다. 피로도를 측정하기 위한 피로도 인덱스를 개발하여 1부터 5까지의 수치로 표현하였다. 또한 피로도 계산 결과와 설문조사 결과와 비교하여 독립표본 t-검정을 실시한 결과 통계적으로 유의한 값이 나왔다. 본 시스템은 사용자들이 건강을 효율적으로 관리하는 데에 활용될 것이다. Recently, smart wearable devices for monitoring health status have been utilized as interest in health care has increased. In this paper, we developed a fatigue measurement system that works with smart wearable devices. Unlike physical fatigue that is restored when you take enough rest, mental fatigue can decrease the efficiency or concentration of work, so you can monitor your mental health status through measurements. This system provides the function to transmit the measured data from the smart wearable device to the smartphone and to calculate the mental fatigue. A fatigue index was developed to measure fatigue and expressed as a number from 1 to 5. In addition, the results of the fatigue calculation and the survey were compared with the results of the independent sample t-test. Therefore, this system will be used to help users manage their health efficiently.

Purpose: This study aimed to examine the pediatric sedation knowledge and performance of nurses in tertiary hospitals. Methods: Altogether 120 nurses working in the Pediatric Departments of 4 tertiary hospitals in Busan and Kyungnam participated in this descriptive survey. The questionnaire was developed based on domestic and international guidelines and consisted of 40 questions including 18 questions on knowledge and 22 on the performance level of sedation nursing. Results: The mean score regarding the knowledge of pediatric sedation care was 3.14 points and the mean performance level score was 3.44 points. Questions that received low scores in terms of pediatric sedation care knowledge included items regarding the latest policies, level of sedation, and fasting before sedation. Questions that received low scores in the performance level included items regarding psychological preparation before sedation, sedation education considering developmental level and disease, and items related to blood pressure measurement. Pediatric sedation knowledge scores were higher in the groups with higher age, longer clinical experience, higher educational experience, and awareness of sedation guidelines. Performance scores were significantly higher in the groups having educational experience in pediatric sedation and in those exhibiting awareness of sedation guidelines. Conclusion: Sedation education was significantly associated with both knowledge and performance of sedation nursing, conducting educational programs on pediatric sedation nursing.

자원 결핍과 인적자본이 행정부담으로 인한 국민기초생활보장제도 미신청에 미치는 영향

김나연 ( Kim Na Yeon ) 한국행정학회 2021 韓國行政學報 Vol.55 No.4

국민기초생활보장제도와 관련하여 가장 활발하게 논의가 되고 있는 부분은 부양의무자 기준의 완화 및 폐지를 통해 수급자를 확대하고 사각지대를 축소하는 것이다. 이러한 비적격 비수급층에 대한 논의에 비해 상대적으로 법으로 규정되어 있는 적용대상이나 어떠한 이유로 국민기초생활보장제도의 혜택을 받고 있지 못하는 적격 비수급 빈곤층의 수급 확대에 대한 논의는 부족하다. 이 연구는 Christensen et al.(2019)의 모델을 바탕으로 자원의 결핍과 인적자본이 행정 부담으로 인한 국민기초생활보장제도 미신청에 어떠한 영향을 미치는지 로짓 모형을 사용하여 분석하였다. 2018 서울시 복지실태조사를 사용하여 행정부담 (학습 비용, 준수 비용, 그리고 심리적 비용)으로 인해 국민기초생활보장제도를 신청하지 않은 응답자를 대상으로 분석한 결과, 자원의 결핍 정도가 높을수록 행정부담으로 인한 국민기초생활보장제도 미신청이 증가하며 인적자본 중 교육수준이 낮을수록, 정신적 건강상태가 좋지 않다고 인지할수록 행정부담으로 인한 국민기초생활보장제도 미신청이 증가하는 것으로 나타났다. 또한 공공부조를 통한 추가적인 소득이 필요하다고 느낄수록 행정부담으로 인한 국민기초생활보장제도의 미신청이 높아지는 것으로 나타났다. The National Basic Livelihood Security (NBLS) program has taken gradual steps to abolish the family support obligation rules, due to the criticism that it created a large number of ineligible and systematically excluded individuals in the determination of program benefits. However, less attention has been paid to people who are eligible but do not claim and receive benefits. Low-income individuals encounter administrative burdens when they interact with government and public officials, and different people respond in different ways to these burdens. Some low-income individuals experiencing administrative burdens do not participate in the NBLS program although they are eligible. Drawing on the model by Christensen et al. (2019), this paper uses the 2018 Seoul Welfare Survey to explore the impact of individual factors (resource scarcity and human resources) on the decision not to apply for NBLS program benefits due to the administrative burden. The logit regression analysis shows that respondents with high resource scarcity are less likely to claim the NBLS program benefits. When it comes to human resource variables, respondents’ low education level and negative perception of their mental health increase the odds ratio of their not applying for program benefits.
