Purpose: To define the concept of digital health literacy and identify its attributes. Methods: Walker and Avant’s approach was employed for concept analysis. Attributes, antecedents, consequences, and the definition of digital health literacy were derived from a review of 28 studies. Results: Digital health literacy was identified to possess the following five attributes: health information seeking, health information processing, health information communication, health-related knowledge translation, and utilizing digital technology. Basic literacy skills, health concerns, motivation to use technology for health information, and access to digital technologies were all antecedents of the concept. The consequences of the concept were health behaviors, patient engagement, health status, and quality of life. Digital health literacy is the ability to seek relevant health information utilizing digital technology to solve health problems and improve quality of life. Furthermore, it refers to the translation of health-related knowledge obtained through health information processing-finding, understanding, and evaluating health information and health information communication-into the context in which individual and social factors interact. Conclusion: This study presented a new definition of digital health literacy that goes beyond existing internet-based eHealth literacy, by incorporating the context of emerging digital technologies. This proposed definition can serve as a foundation for the development of instruments and educational programs to improve individuals’ digital health literacy.

지역사회 정신건강서비스 이용자와 비이용자의 지역사회통합 수준 비교

이민화(Lee, Minhwa),황태연(Hwang, Taeyeon),서미경(Seo, Mikyung) 한국정신건강사회복지학회 2021 정신보건과 사회사업 Vol.49 No.1

본 연구는 지역사회 정신건강서비스가 정신장애인의 지역사회통합을 목적으로 한다는 전제하에 우리나라 지역사회서비스 이용여부에 따른 지역사회통합 수준의 차이를 분석하고자 하였다. 이를 위해 지역사회에 거주하는 정신장애인 중 정신건강서비스를 이용하는 자 142명과 서비스를 이용하지 않고 정신의료기관에서 외래치료만 받는 비이용자 140명의 지역사회통합(물리적, 사회적, 심리적 통합) 수준을 조사하였다. 먼저 지역사회통합의 예측요인을 분석한 결과, 대상자의 연령, 직업유무, 자원접근성이 통합을 의미 있게 예측하는 요인이었다. 이러한 예측요인들을 공변인으로 설정하고 이를 통제하여 두 집단의 세 가지 영역의 통합수준을 비교하였다. 그 결과 물리적 통합에서만 이용자의 통합수준이 의미 있게 높았고, 사회적 통합의 사회관계망 크기는 비이용자가 더 높았다. 그리고 사회적 통합의 두 번째 차원인 접촉빈도와 심리적 통합은 집단 간 차이가 없었다. 이러한 결과를 바탕으로 연구자들은 우리나라 지역사회서비스 이용여부가 지역사회통합에 의미 있는 기여를 하지 못하고 있음을 지적하며 정신장애인 회복에 특히 중요한 사회적 통합을 높이기 위한 가능한 대안을 제안하였다. Community mental health services are looking forward to community integration for people with mental disorders. The aim of the study is to analyze the contribution levels of community integration of community-based services compared to 142 people with mental disorders who use the community mental health service and 140 non-users who only use outpatient treatment. Each participants completed a series of questionnaires including physical, social, and psychological integration. We noted that age, job, resource accessibility were a significant predictor of community integration. By controlling these predictors as covariates, the two groups differed significantly in terms of physical integration and social network size, but there was no significant difference in social contact frequency and psychological integration. As a results, we suggest that community-based services should be improved in order to increase the level of community integration.

마비 말 장애의 발화 명료도와 음성 인식률 비교

황유미(Yumi Hwang),김선희(Sunhee Kim),정민화(Minhwa Chung) 한국HCI학회 2011 한국HCI학회 학술대회 Vol.2011 No.1

본 연구는 개인마다 음성 변이가 다양하고 명료도가 낮은 마비 말 장애 음성에 대하여 기존에 사람이 수행하던 발화 명료도 평가가 음성 인식 시스템에 의해 대체될 수 있는지를 고찰하는 것을 그 목적으로 한다. 이를 위하여 5 명의 뇌성마비 화자의 각 194 개 단어 음성데이터를 대상으로 화자 독립과 화자 적응 방식에서 각각 음성인식 실험을 하고, 8 명의 청자가 화자 당 50 개 단어를 듣고 철자 전사와 5 점 척도의 명료도 평정 평가를 실시한 다음, 음성 인식률과 사람의 평가 점수를 비교하였다. 실험 결과 화자 적응 방식의 음성 인식률과 전사점수 사이에 매우 큰 양의 상관관계(0.99 이상)가 나타났는데, 이는 화자 적응 방식의 음성 인식률이 마비 말 장애 화자들의 음성을 전사 점수에 의한 명료도와 거의 비슷한 양상으로 구분한다는 것을 보여주어, 음성 인식 시스템에 의한 명료도 자동 구분의 가능성을 시사한다. Dysarthric speech indicates various phonetic variations for each person and low intelligibility. This paper aims to examine whether speech intelligibility assessment which has been usually done by human can be replaced by a speech recognition system. For this purpose, two experiments with a speaker independent system and a speaker dependent system were performed with 194 words spoken by each person of 5 speakers with cerebral palsy. 8 listeners evaluated 50 utterances of each speaker by transcribing and rating in 5-scale per each word. Finally, the recognition rate of dysarthric speech by the speech recognition system is compared to the rate of human listeners. The results indicate that the speaker-adaptive speech recognition accuracy and human transcription score is highly correlated and suggest that a speech recognition system could be employed for the automatic intelligibility assessment of dysarthric speech.

Nutritional Status and Risk Factors of Malnutrition in Korean Older Men Living Alone: A Secondary Data Analysis

Gahye Kim,Minhwa Hwang,Seonghyeon Lee,Yeon-Hwan Park 한국성인간호학회 2021 성인간호학회 학술대회 Vol.2021 No.8

Aim(s): Malnutrition is common among older adults and is associated with increased risks of many adverse health outcomes including frailty and poor quality of life. Older men living alone are a vulnerable social group who have a higher risk of poor nutrition than those living with others or women living alone. However, little is known about factors related to malnutrition in older men living alone. This study aimed to investigate the nutritional status and identify risk factors related to malnutrition in Korean older men living alone. Method(s): We analyzed the secondary data of 230 older men aged 65 years and over without severe cognitive impairment in the prospective cohort study of Korean elderly living alone conducted in 2019. Nutritional status was measured using the Mini Nutritional Assessment-Short Form (MNA-SF). Analyzed data included demographic factors (age, income), health condition (comorbidity, polypharmacy), physical (instrumental activities of daily living), cognitive (Mini-Mental Stated Examination), psychological function (depression), and lifestyle (smoking, drinking, exercise, meal frequency). Binary logistic regression analyses were performed. Result(s): Participant's mean age was 74.23±5.70 years. Of the participants 32.2% had malnutrition and 67.8% normal nutritional status. Factors related to malnutrition in older men living alone were income (Odds Ratio [OR]=.37, 95% confidence Interval[CI] = 15-.89), polypharmacy (OR=2.47, 95% CI=1.28-4.77), depression (OR=2.20, 95% CI=1.14-4.24), smoking (OR=2.51, 95% CI=1.27-4.97), low meal frequency (OR=4.13, 95% CI=2.11-8.07). Conclusion(s): It is important for the elderly men living alone to take a comprehensive nutritional assessment including socioeconomic status, health condition, psychological function, and lifestyle to prevent malnutrition. Strategies to improve healthy lifestyles and reduce depression are needed for effective nutritional management of older men living alone.

마비말장애 발화유형 구분에 영향을 미치는 /a/ ('ㅏ') 모음의 섭동적 특성 분석

황유미(Yumi Hwang),김선희(Sunhee Kim),정민화(Minhwa Chung) 한국HCI학회 2012 한국HCI학회 학술대회 Vol.2012 No.1

본 연구는 마비말장애 음성의 섭동적 특성이 마비말장애 발화 유형을 자동으로 구분하는 자질로 사용될 수 있는지 확인하는 것을 그 목적으로 한다. 먼저 세 가지 유형(경직형, 이완형, 실조형)의 마비말장애 화자가 발화한 /a/ ('ㅏ') 모음을 대상으로 음도, 강도, 음질, 유성성, 진동의 측면에서 섭동적 특성을 측정한 다음, 통계분석을 통해 모음의 섭동적 특성이 발화 유형에 따라 차이가 나타나는지를 살펴보았다. 그 결과 마비말장애발화 유형에 따라 음성의 섭동적 특성이 다르게 나타남을 확인할 수 있었다. 이러한 결과는 마비말장애인을 위한 음성 인식기 개발 시 발화 유형에 따른 음향모델 및 어휘모델을 구축하기 위한 기초 자료로 이용될 수 있다. This study aims to investigate whether the temporal dynamic perturbations can be used as classifying factors of different types in dysarthria. We measured the perturbations of the vowel /a/ ('ㅏ') produced by the subjects who were diagnosed as having three different types of dysarthria (spastic, flaccid, ataxic) using parameters, such as pitch, intensity, voice quality, voicing, and pulses. Then, statistical analysis of the measured features was performed to examine the differences of three types of dysarthria. As a result, the dynamic temporal perturbation in the vowel /a/ ('ㅏ') showed significant differences according to three different types of dysarthria. These results will contribute to the development of acoustic and lexical models of speech recognition systems for users with dysarthria.

Gahye Kim,Minhwa Hwang,Seonghyeon Lee,Yeon-Hwan Park 한국영양학회 2024 Nutrition Research and Practice Vol.18 No.3

BACKGROUND/OBJECTIVES: Older men who live alone are more vulnerable to poor nutrition. However, little attention has been paid to malnutrition among this population. This study aimed to examine malnutrition and its associated factors among communitydwelling older men living alone. SUBJECTS/METHODS: This cross-sectional descriptive study used cohort data of community-dwelling older adults living alone in South Korea. A total of 230 older men aged 65 and over were included in this study. Nutritional status was assessed using the Mini Nutritional Assessment-Short Form. Multidimensional factors (sociodemographic, health-related, psychosocial, and lifestyle characteristics) were evaluated. Hierarchical logistic regression analyses were conducted to identify the malnutrition-related factors. RESULTS: The prevalence of malnutrition was 32.2% in older men living alone. Low income (odds ratio [OR], 2.44; 95% confidence interval [CI], 1.01–5.90), polypharmacy (OR, 2.23; 95% CI, 1.16–4.28), suicidal ideation (OR, 2.13; 95% CI, 1.02–4.45), meal skipping (OR, 3.26; 95% CI, 1.60–6.64), and smoking (OR, 2.86; 95% CI, 1.43–5.73) were significantly associated with malnutrition. CONCLUSION: Malnutrition is a severe health problem in older men living alone. This study highlights the importance of comprehensive and tailored interventions to mitigate malnutrition among older men living alone.
