목적 : 미세먼지가 젊은층과 노년층의 눈물막에 영향을 미치는지 알아보고자 미세먼지 농도 수준에 따라 눈물의 양, 안정성 및 지질층 두께 변화를 평가하였다. 방법 : 안질환이 없는 20대와 60대 각각 25명(총 50명)이 참석하였고, 한국환경공단에서 제공된 미세먼지 좋 음 수준(0~30 ㎍/m³)과 나쁨 수준(51~100 ㎍/m³)에서 각각 이들을 대상으로 눈물 검사를 하였다. 눈물양은 OCCUTUBE(OccuTech Co., Seongnam, Korea)로, 눈물막 안정성은 침습성눈물막파괴시간(TBUT), 비침습성 눈물막파괴시간(NIBUT)로 지질층 두께는 Lipiview® 로 평가하였으며, 건성안 관련 증상은 OSDI 설문지를 이용 하여 평가하였다. 미세먼지 수준에 따른 비교는 SPSS version 21.0(SPSS Inc, Chicago, IL, USA)를 사용하여 분석하였다. 결과 : 젊은층과 노년층 모두 미세먼지 나쁨 수준인 날에서는 눈물의 양과 안정성이 미세먼지 좋음 수준인 날과 비교하여 유의하게 감소하였으나(p<0.050), 지질층 두께와 OSDI 설문값은 미세먼지 수준에 따라 젊은층과 노년층에서 모두 유의한 차이가 없었다. 미세먼지 농도가 증가할수록 OCCUTUBE 검사값과 TBUT 와 NIBUT는 감소하는 상관성을 보였으며, 노년층의 상관계수(r=0.35, p<0.001, r=0.47, p<0.001, r=0.52, p<0.001, respectively)가 젊은층의 상관계수(r=0.34, p<0.001, r=0.37, p<0.001, r=0.40, p<0.001, respectively)보다 다소 높았다. 결론 : 미세먼지는 젊은층과 노년층에의 눈물의 양과 안정성을 감소시켜 건성안 유발요인으로 작용할 것으로 사료된다.

목적 : 한국인 노년층을 대상으로 건성안 관련 요인을 분석하고자 하였다. 방법 : 노년 36명(72안, 남 17명, 여 19명, 평균연령 62.11±4.84세)을 대상으로 SPEED 건성안 설문지를 이 용하여 건성안을 판별하고, 눈물의 양은 OCCUTUBE로, 눈물막 안정성은 눈물막파괴시간검사(TBUT)로 평가하였 으며, 눈물막 지방층 두께(LLT)와 눈깜박임 양상 및 마이봄샘 이상은 LIPIVIEW IIⓇ로 측정하고 Image J® 프로 그램을 이용하여 분석하였다. 결과 : 건성안의 SPEED 설문값은 10.11±4.91점, OCCUTUBE 측정값 및 TBUT는 각각 3.38±1.15 mm, 4.49±1.31초로 정상안과 차이가 없었으나, 지질층 두께는 80.36±20.78 nm로 정상안보다 두꺼웠다(p=0.021). 마이봄샘이 손상된 grade(MG dropout, MG curling, Gland thickness)는 각각 1.17±0.70, 0.47±0.61, 0.61±0.60로 정상안보다 유의하게 손상이 심했다. 지질층 두께는 SPEED 설문값과 양의 상관성을 보였고(p<0.009), 마이봄샘 손실률과 음의 상관성을 보였고, 마이봄샘 손상도는 마이봄샘 비대 및 손실과 상관성이 있었다(p<0.050). 결론 : SPEED 설문지로 감별한 노년층 건성안의 원인은 눈물막 지질층 두께와 관련이 있으며, 지질층 두께는 과분비성 마이봄샘 기능이상과 관련이 있는 것으로 사료된다.

The purpose of this study was to investigate the comparison of nutrient intake and metabolic syndrome between single person households and non-single person households in elderly subjects. We analyzed data from 2,903 subjects ≥ age 65 who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2013~2015. As a result, single-person households had lower income and economic ability, overall nutrient intake was deteriorated, and the proportion of high-carbohydrate intake was high, compared to non-single person households. After adjusting for potential confounders (sex, age, education, household income, economic activity, smoking status, alcohol consumption, walking frequency, health status, depression status, and dietary factors), the singleperson household showed a tendency of 1.22-fold higher ORs of metabolic syndrome and 1.3-fold higher ORs of hypertriglyceridemia than the non-single-person household. We suggest that the single-person household may be associated with increased prevalence of metabolic syndrome and hypertriglyceridemia in the elderly subjects.

The present study analyzed data from the 3D measurement of the feet of men aged over 20 years residing in the capital region as part of the 6th Anthropometry of Size Korea. To analyze the characteristics of the foot shapes of young men aged 20~39 years and middle-aged/elderly men aged 40~69 years by age and by type, a cluster analysis was conducted using the factors derived through the factor analysis as independent variables. The results of the study that analyzed the characteristics of foot shapes by type according to differences in age were as follows. First, through the analysis of the characteristics of the foot shapes of young men by type, five factors were extracted, and the foot shapes were classified into three types: Type 1 (short and flat), Type 2 (thick), and Type 3 (long and wide). Second, through the analysis of the characteristics of the foot shapes of middle-aged/elderly men by type, six factors were extracted, and the foot shapes were classified into four types: Type 1 (short and regular), Type 2 (flat), Type 3 (thick), and Type 4 (long and regular). The results of the present study are expected to serve as basic data for the design of shoes by age and foot type.

The purpose of this study is to conduct basic research on development of game interface for the elderly by verifying the difference in user experience based on the type of interface. The methodology of playtest combining experimental research and survey was applied with subjects of elderly users consisting of 47 men and 48 women being ages 60 and up. The effects of user experience between natural user interface and the pad-type interface were compared and analyzed through repeated measure MANOVA in terms of emotional response, ease of use and flow. The NUI game showed higher emotional responses such as pleasure and dominance. On the other hand, there was no difference in arousal. The NUI game also presented higher ease of use in the process of game play and it also had higher autotelic experience, action-awareness merging, sense of control and ambiguous feedback experience. These results may contribute to the development of serious game and natural user interface for the elderly by empirically identifying the effects of user experience on NUI.

It is emerging that spouse existence is very high as 674 persons(75.3%) in the answer for marriage or not, couple family to live with unmarried children is very high as 483 persons(54.0%) in the answer for family composition, leaving high school in mid-course or gradation of high school are very high as 356 persons(39.8%) in the answer for school career, income from 3 million Won under 4 million won is very high as 260 persons(29.1%) in the answer for monthly income of family members, and women to use under 50 thousand won is very high as 510 persons(57.0%) in the monthly average expense to be used for skin management. In this study, this researcher extracted total 5 factors (economic saving, displaying consumption, confidence inclination, centering around family, and leisure application) by executing factor analysis with 12 question items of lifestyle so as to grasp factor structure of lifestyle of middleaged and old age people, and whole explanatory variable quantity was 70.9%. This researcher named as economic saving type, diplaying consumption style, and type centering around leisure and family, after making multitude analysis about 5 factors analyzed by measuring lifestyle feature. As the result of structure analysis of question items of skin management(pursuit of skin management, life of skin management, and inclination of skin management), this researcher extracted total 3 factors, and whole explanatory variable quantity was 71.30%. Thus, it emerged that there is significant difference among groups.

Understanding awareness and wearing behavior of functional textiles for silver generation is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research, a survey was developed and the aged 50 and above were 332 respondents. The results of the study are as follows. First, the level of awareness for both comfort-oriented and health/safetyoriented functional fabrics in high health-conscious group was much higher than that in low health-conscious group. In number of wearing times, health body and high-conscious group wear comfort-oriented fabrics more frequently, while weak body group wear health/safety-oriented fabrics more often. The health-consciousness significantly influenced the possession of active sportswear with various functions. Second, the awareness of functional fabrics in exercise activities groups was much higher than that in exercise-conscious groups. High exercise activities group know more about the wet sensation-related fabrics and clothing materials for outdoor activities. Low exerciseconscious group put on health/comfort-oriented fabrics for casuals more frequent than functional fabrics for sportswear. High exercise activities group preferred to wear sportswear suitable for outdoor activities. The aged people have a lot of health/comfort-oriented functional casual wear appropriate for indoor activities regardless of exerciseconsciousness. However, the more they enjoy exercise activities the more they are interested in functional sportswear. Even though they were unconcerned with exercise, older people are interested in functional casual clothes. As a conclusion, the high interest in health and exuberant activities in silver generation arose the necessity of new multi-functional clothing products.

The purpose of this study is to explore the applicability of QFD to product development of clothes by empirically applying it to development of a specific clothes, middle and elderly women’s formal knitwear. The voices of customers(VOCs) for formal knitwear was collected through in-depth interviews with 25 customers, shop masters, and designers. Also, questionnaires of which respondents were 230 customers were used to rank the importance of the items of VOC. A QFD team of 10 knitwear experts implemented the task of translating VOCs into design attributes and measuring the values of the relationships between VOCs and design attributes. Importance ranking of the items of design attributes was obtained based on Lyman’s method. The results of this study were as follows. First, the customer requirements for formal knitwear were classified into five dimensions, that is, symbolism, aesthetic, fitness, usefulness, and maintenance. Second, the descending order of the necessity of improving the quality was maintenance, aesthetic, fitness, usefulness, and symbolism. Third, three-staged design attributes were obtained as a result of translating of VOCs into design attributes. Lastly, the descending order of the importance of design attributes was “sorts of yarn”, “sorts of color jacquard”, “color”, “tone”, “ease”, etc.

This study investigates the retention of Japanese as a second language in Korean elders' Japanese, which has been in a frozen state since 1945. Transcripts of conversations with young and middle-aged Japanese native speakers and questionnaires were used in the research. The following conclusions regarding aspect of Japanese existences were found as a result of this study: (1)In the case of the animate predicate, the dialect form ORU is the most frequently used. (2)Judging from the degree of contact with Japanese and their current Japanese ability, they use it together with ARU in lower than middle group, but use only ARU at the lowest group. (3)ORU, acquired from Japanese teachers, is often used to refer to teachers, but is neutral in formality. (4)The retention of ORU and the convergence to ARU are assumed to have occurred from 1945 until the present. (5)It is observed that ‘the fossilization of ARU’, ‘the cognitive linguistic reconstruction of RU-forms’ and ‘the use of ARU by L1(Korean) interference’ are the linguistic factors that brought about the retention of a system of Japanese existences.

The purpose of this study is to investigate the relationship of periodontal disease to self-reported history of stroke in the elderly(60 years of age and older) with a special emphasis on elderly women. Data from the Third National Health and Nutrition Examination Survey(NHANES III), a large population-based cross-sectional survey of the United States, were utilized for this study. Since we have 1,563 edentulous subjects from a total of 5,123 subjects and periodontal disease is a major cause of tooth loss, it was necessary to account for this in our statistical analysis. Hence, we developed a new index called the Periodontal Health Status(PHS) index. In the logistic regression models with stratification by gender, males did not show statistically significant relationship between Periodontal Health Status(PHS) and stroke history. In contrast, females showed some marginal association between Periodontal Health Status(PHS) and stroke history. Further longitudinal intervention studies need to be conducted to determine the temporal relationship between periodontal disease and stroke
