The relationship between mortality and the Korean Healthy Eating Index ("KHEI") is well established. This study was to investigate the associations between health habits, mental health, and nutritional status and KHEI in older Koreans (aged≥65 years). A total of 4,247 subjects (1,842 men and 2,405 women) that participated in the 2016~2018 Korean National Health and Nutrition Examination Survey were included in the analysis. The lowest scoring KHEI item was milk and milk products. KHEI tertile groups were classified by total KHEI score. Tertile group percentages were related to general characteristics such as gender, residential area, educational level, income level, number of family members, and age. Logistic regression analysis adjusted for general characteristics, showed that ex-smokers (OR: male 1.53 female 2.29), smokers (OR: male 2.90), low hand grip strength (OR: male 1.42 female 1.90), poor self-rated health status (OR: female 1.83), stressful mental status (OR: female 1.51), poor health-related quality of life (OR: female 1.64), poor nutritional status (OR: male 2.88~37.20 female 1.98~16.12), and food insecurity (OR: male 6.87 female 2.03) were significantly related to a lower KHEI. This study suggests that gender-specific associations exist between mental health status and KHEI.

As diseases are already increasing due to aging population and changes in eating habits, interest in digital healthcare is increasing. According to the 2020 Elderly Status Survey, 84% of South Koreans aged 65 and older suffer from at least one chronic disease, and the number and duration of drugs taken by the elderly are also increasing. Effective management that enhances compliance of chronic disease patients can prevent the onset of complications, thereby averting progression to severe illnesses. Thus, a proper medication-taking habit is crucial. This paper proposes a medication information retrieval system using OCR technology. By leveraging Google Cloud Vision API, the system detects and recognizes the names of medicines. Once recognized, the medication name is searched in a database to provide users with medication information and medication schedule management services. By providing accurate medication information through the search, it is possible to induce changes in medication methods and habits. By eliminating the inconvenience of direct input through OCR technology, we anticipate enhancing user convenience by promptly delivering information.

Purpose: The aim of this study was to predict the subgroups vulnerable to poorer health-related quality of life (HRQoL) according to gender in older adults. Methods: Data from 5,553 Koreans aged 65 or older were extracted from the Korea National Health and Nutrition Examination Survey. HRQoL was assessed using the EQ-5D tool. Complex sample analysis and decision-tree analysis were conducted using SPSS for Windows version 27.0. Results: The mean scores of the EQ-5D index were 0.93 ± 0.00 in men and 0.88 ± 0.00 in women. In men, poorer HRQoL groups were identified with seven different pathways, which were categorized based on participants' characteristics, such as restriction of activity, perceived health status, muscle exercise, age, relative hand grip strength, suicidal ideation, the number of chronic diseases, body mass index, and income status. Restriction of activity was the most significant predictor of poorer HRQoL in elderly men. In women, the poorer HRQoL groups were identified with nine different pathways, which were categorized based on participants' characteristics, such as perceived health status, restriction of activity, age, education, unmet medical service needs, anemia, body mass index, relative hand grip, and aerobic exercise. Perceived health status was the most significant predictor of poorer HRQoL in elderly women. Conclusion: This study presents a predictive model of HRQoL in older adults according to gender and can be used to detect individuals at risk of poorer HRQoL.

The study on social robots has been actively conducted in the robot research community. In the area of robot design, however, there are few studies regarding robot motions that are one of the methods for interaction between humans and robots. This is a preliminary study to find preferred human motions that can be applied to social robots. We conducted a two-phased empirical study about preferred human motions. In the first phase, four representative human motions, such as 'greeting', 'I don't know', 'positive answer', and 'giving', were captured through 28 body makers and video recording. 10 young and 6 elderly Singaporeans participated in the motion capture process. In the second phase, the communication efficiency, emotion, and satisfaction of the human motions recorded in the first phase were measured by a questionnaire and 31 young Koreans, 35 young Singaporeans participated to investigate cultural differences. We drew the conclusion that motions used in the same culture are efficient in communication and also give friendliness and satisfaction. In addition, regardless of user's culture, young people's motions and female motions were preferred in terms of communication efficiency, emotional aspect, satisfaction.

Purpose: The purpose of this study was to identify the research trends and instruments for assessment of sleep quality in Korea. Methods: 66 quantitative research reports published from 2000 to March 2009 in Korea were selected from 5 databases: RISS4U, KISS, KISTI, DBpia, and the National Assembly Library and were analyzed according to criteria such as publication years, type of journal, participants, study fields, research design, participants, key words and instruments for assessment. Results: Research in sleep quality has been rapidly increasing in recent years. More than half of the research analyzed was conducted in nursing. The majority of research methods were survey and correlational research. Patients with chronic illness and the elderly were the major subjects in those researches. Most research was performed based on hospitals and communities. The types of variables tested for their relation and influence on sleep quality were quite limited. With respect to the instrument used for assessing sleep quality, most studies did not consider whether or not the validity of their instrument had been established. Conclusion: It is recommended to conduct clinically applicable interventional research with an experimental design and to develop a reliability and validity established sleep quality instrument for Koreans.

In order to investigate the differences of nutrient intakes by the economic status and different age groups and to identify the nutritional risk group and its specific nutrition problem, 2001 Korean National Health and Nutrition Survey were analyzed. The subject's numbers of 9,391 were classified into four classes such as low (14.2%), medium (37.2%), high (26.0%), and high above (22.6%) on the basis of the family monthly income and the 2001 Korean minimum cost of living according to the family size. Mean intakes of energy and all nutrients assessed by the RDAs, lipid-energy %, and MAR were increased as the economic status were going up. Na intake expressed per 1,000kcal was in reverse. Nearly a half(45.5%) of the low-income people seemed to take nutritionally inadequate diet in consideration with MAR values. Deficiencies of iron and even energy in the toddlers (1 to 2 years) of low-income class were of great concern. Adolescent age group has been observed that their calcium and iron intakes, and possibly energy, were appeared to be the most deficient among all the age groups regardless of the economic status. For the elderly in all the economic status except high-above class, calcium, vitamin A, and riboflavin were commonly deficient nutrients. Calcium deficiency was appeared throughout nearly all the ages except toddlers and all the economic classes. Even in the high-above class 57.3% took insufficient amount of calcium.

The purpose of this study is to compare the hairstyles between Korean and Australian women, who have different individual hair characteristics, social backgrounds, and culture from each other. Data were collected through a survey of 208 Australian females and 392 Koreans. Frequency analysis, t-test, and two-way ANOVA were used to analyze the data. The results are as follows: Korean and Australian women maintain a hairstyle for six months or less in most of the cases. They preferred a hairstyle with bang, and the elderly especially a shorter hair length. Choosing their hairstyles depended on such factors as hair length, dyeing, form of face, harmony with clothing, and social status. There was no difference, however, in a preferred hair length. Korean women possessed brown and black hair colors in a descending order, whereas Australians light blonde and brown in a descending order as well. There was a big difference in the preference for a permanent wave. Korean women preferred to give a volume or curl to their hair, while Australians wanted to have a straight hair. According to the study on a hairstyle behavior, it was found that there were differences in fashion and individuality between two countries and also in dependency among age groups, whereas no differences existed in beauty.
