Purpose: The purpose of this study is to investigate the effect of work intensity on fit factor and affective quality of the dustproof Background: Among the victims who suffer pneumoconiosis due to the inhalation of toxic substances or the lack of oxygen during the work, the proportion of the victims is larger than the other causes. Wearing a respirator may prevent pneumoconiosis, but it can be hazardous to workers because of the leakage through filters, cartridges, exhaust valves, broken parts, and face-to-face contact. Despite leakage through the contact area between the mask and the face has various causes such as the wearer's activity, sweat accumulation, facial shape, etc., There is a lack of relevant research and regulation compared to developed countries that have already institutionalized the law 30 years ago and give the right to sell through a test Method: The work intensity was adjusted by walking or running at 6km/h and 11km/h on the treadmill, and tasks were defined with reference to the test procedure and the exercise sequence applied in the face leakage test of the dustproof mask. And fit factor was measured objectively using 'Respirator Fit Tester 8038' which measures fit factor calculated by dividing the number of dust present outside the mask by inside the mask. In addition, affective quality was classified by the ease of use, ease of breathing, and ease of wearing, and was measured using the 5-point likert scale questionnaire. Results: There was a significant difference in fit factor, ease of breathing, and wearing convenience according to work intensity and no significant difference in ease of use(${\alpha}=0.01$). And when the work intensity was high, fit factor, ease of breathing, and wearing convenience were all lower than when the work intensity was low. Conclusion: In Korea, it is necessary to consider consideration of the work intensity when testing the leakage rate of the face part for safety certification of the respiratory protective equipment, When developing a mask, it should be possible to maintain high adhesion even under intense, active situation and high temperature conditions by selecting materials, improving the wearing style, and expanding the adjustable range.

Purpose: This study was to compare changes in health behaviors, motivational factors, cardiovascular risk factors, and functional status (SIP) after implementing the 6-month motivation-enhancing program to institutionalized elderly women. Methods: Sixty-four elderly women participated. Face to face interviews with blood sampling and anthropometric assessment were conducted at the pretest, 10 weeks and 6 months during the program. Results: 1. The program participants showed significantly better health behaviors over 6 months. The mean motivational level was also significantly improved, especially for perceived benefits, perceived barriers, and emotional salience. 2. The mean of cardiovascular risk factors for the participants was 21.8 at the level of low to moderate risk. After completing the program, total risk score was significantly decreased to 18.7 at 10 weeks, and further to 17.7 at 6 months. A significant reduction was also found in HDL and LDL-cholesterol levels, blood pressure, obesity, inactivity, and stress. 3. The functional status (SIP) was 11% at the baseline and significantly changed in positive direction at 10 weeks(M=9.3) and at 6 month(M=6.3). The significant improvement was also found in physical and psychosocial dimensions and sleep/rest dimension. Conclusion: The motivation enhancing program was effective to reduce cardiovascular risks and to improve the functional status of institutionalized elderly women by motivating them to perform better health behaviors.

In this research, we designed a teacher professional development (PD) program where a small group of mathematics teachers could share, reflect on, and discuss their pedagogical knowledge and practices of ICT-integrated lessons, using a video annotation tool called DIVER. The main purposes of this paper are both micro and macro: to examine how the teachers were engaged in the meaning-making process in a video-based PD (micro); and to derive implications about how to design effective video-based teacher PD programs toward a teacher community of practices (macro). To examine teachers' meaning-making in the PD sessions, discourse data from a series of 10 meetings was segmented into idea units and coded to identify discourse patterns, focusing on (a) participation levels, (b) conversation topics, and (c) conversation depth. Regarding the affordance of DIVER, discourse patterns of two meetings, before and after individual annotation with DIVER were compared through qualitative vignette analysis. Overall, we found that the teacher discourse shifted the focus from surface features to deeper pedagogical issues as the PD sessions progressed. In particular, the annotation function in DIVER afforded the teachers to exercise descriptive analyses of video clips in a flexible manner, thereby helping them cognitively prepared to take interpretative and evaluative stances in face-to-face discussions with colleagues. In conclusion, deriving from our research experiences, we discuss the possibilities and challenges of designing video-based teacher PD in a school context.

Purpose: This descriptive study was done to develop a predictive model of depression in rural elders that will guide prevention and reduction of depression in elders. Methods: A cross-sectional descriptive survey was done using face-to-face private interviews. Participants included in the final analysis were 461 elders (aged${\geq}$ 65 years). The questions were on depression, personal and environmental factors, body functions and structures, activity and participation. Decision tree analysis using the SPSS Modeler 14.1 program was applied to build an optimum and significant predictive model to predict depression in rural elders. Results: From the data analysis, the predictive model for factors related to depression in rural elders presented with 4 pathways. Predictive factors included exercise capacity, self-esteem, farming, social activity, cognitive function, and gender. The accuracy of the model was 83.7%, error rate 16.3%, sensitivity 63.3%, and specificity 93.6%. Conclusion: The results of this study can be used as a theoretical basis for developing a systematic knowledge system for nursing and for developing a protocol that prevents depression in elders living in rural areas, thereby contributing to advanced depression prevention for elders.

Today, the art and the architecture face up to the problem of loss of direction. So, the derection of post have been lost. This phenomina cause the second loss of direction, because the mode of pre-modernism is underestimated. After all, the mode and philosophy of after-modernism face up to the new crisis of derection. Present artists, archtectures and designers have to acnieve new trial and study for estimation of aestetics and directions. Ultimately, constant exercise and study of philosophy, morpholophy, morphology, current mode and new materials is necessary to search a methodology. This all have to be accomplished by the clear philosophy. The original identity is formed in environmental basis. So, first, architectures, designers, and artist understand native identity, second, we sho have acadenical and practical faculties impose significance. In case of Europe, the change of mode have led paradigm of culture. The great change of social culture have come out the wave of revolution that cross in design, architecture and art. 1920's of modernism evolve 1960's completion. In the change of life style, functionalism have evolved postmodernnism. But, in this change we do not suggest the new derection that form concrete idea and sympathy. This phenomina appear in the end of a centry, and nowaday is that day. This trends effect on artists, architectures, and designers, and design and will be changed. Finally, we need to study of concrete and new direction in this circumstance.

As the elderly population increases, the number of patients with various joint diseases, including degenerative arthritis, is steadily increasing. CPM medical devices are needed to effectively treat degenerative arthritis that is common in the elderly population. Domestic CPM medical devices have limited functions and are highly dependent on imports for expensive imported medical devices. To solve this problem, we designed a ROM measurement function using a current sensor that is not present in existing composite joint CPM medical devices. The algorithm was designed using the fact that the force caused by joint stiffness greatly increases the current flowing through the DC motor. In addition, the need for digital healthcare in the medical field is gradually expanding as the proportion of chronically ill patients increases due to the spread of the non-face-to-face economy due to COVID-19 and the aging population. Therefore, this paper aims to improve the performance of CPM medical devices by allowing real-time confirmation of rehabilitation exercise information and operation range measurement results in accordance with digital healthcare trends through a Bluetooth application developed as an Android studio.

Purpose: The purpose of this study was to investigate the relationships between a experience of falling, fear of falling, depression, and perceived health status in urban areas. Methods: After obtaining Institutional Review Board (IRB) approval, a one-time, face-to-face, and private interview was conducted with each participant who was eligible and agreed to participate in this study from May 2007 to August 2007 by trained graduate-level nursing students. The questionnaires consisted of Fall Efficacy Scale, K-GDS, and SF-36. The collected data were analyzed with SPSS/PC 12.0 program, which was used for frequency, percentage, mean, standard deviation, t-test, and hierarchical regression. Results: The major findings of this study were as follows; 1) approximately 9% of participants had fallen within one year. Study participants reported moderate fear of falling(M=43.80); moderate physical health (M=42.31) and mental health(M=46.05); and low depression status(M=10.38). 2) there were significant differences in fear of falling according to gender, experience of falling, exercise, and depression. 3) significant factors influencing on fear of falling were experience of falling and physical health status. Conclusion: The results of this study indicate that nurses working closely with older adults should be taught the impact of previous falls and physical health status on fear of falling and need to reinforce exercise behavior for older adults who are vulnerable to fear of falling.

Objectives: This study was conducted to investigate the correlation between the health-related quality of life assessment according to socio-demographic characteristics, health behavior, and BMI for Gyeonggi-do community population. Methods: The 2012 Community Health Survey data was used. The data were collected by using a cross-sectional study with face-to-face interview. The variables of smoking, AUDIT, exercise, BMI, and Euroqol EQ-5D instrument were selected for analyses. The Difference on the EQ-5D index among groups were tested with Mann-Whitney U test and Kruskal Wallis test. Results: The EQ-5D index for Gyeonggi-do community was 0.951(${\pm}0.104$). The index were significantly different by sex, age, marital status, education level, and occupation. The health-related quality of life showed lower EQ-5D index in women than men, older than young, and less educated. The index were significantly different by health behavior (smoking, drinking, moderate physical activity and exercise) for both men and women). For BMIs, the index was lower to under-weighted male and over-weighted female. Conclusions: The findings suggest that the future intervention of health promotion programs should be carefully designed and tailored by health behavior and obese groups.
