The purpose of this study was to provide the design guidelines for the activity spaces in the skilled nursing facilities for the elderly through the investigation of the spatial characteristics and using behavior The researcher interviewed the staff regarding programs in 15 facilities, investigated and observed the use of the spaces from 15th of December, 2004 to 19th of February, 2005. The programs in facilities were categorized into human knowledge, arts, music, exercise, recreation, cooking gardening, religious and social activities, and those were peformed once to 4 times a day. They were conducted in the elderly individual rooms, lounges, program rooms, dining room, or(and) auditorium. The results of the study were as follows: First, investigating the activity spaces, the lounges and elderly individual rooms were mostly on the same floor so that the elderly had no big trouble in access to the lounge. The program rooms of the facilities in suburban and rural area were on the same floor as the elderly individual rooms and they were likely to combine with another usage, compared to those On city were mostly separated from the residence floor. Most of dining rooms and auditorium were on the basement or on the 1st floor. Second, in the programs by the activity spaces, elderly individual room and the program room were used more for the human knowledge and art programs with small group. The lounges were for recreation and social activities with (both of) small or(and) big group and dining rooms were mainly used for cooking programs. In auditorium, recreation, religious and social activity were performed with big group. Third, the individual rooms for the elderly had more capacity if those did not have any beds, but often had a trouble in making a passage way. The lounges needed to remove decorations and displayed furniture obstructing the passages and to arrange both of the western and eastern type of tables for the efficient use of the spaces. It took a long time in preparation of the furniture and other equipment if the program room was with another usage.

This study was to understand the relationship between emergency room visit due to illness and personal health behaviors as well as population and illness characteristics of elderly patients with diabetes. This study was a descriptive correlation study that analyzed 956 respondents aged 65 or older and diagnosed with diabetes in the Korean Health Panel's data from 2014 to 2017. Data were analyzed using the SPSS 26.0 program with Mann-Whitney U test, chi-square test, and logistic regression analysis. The respondents who visited emergency room had fewer days of moderate-intensity physical activity and walking activity, were older, had activity restrictions due to disability, had depression, and had a large number of comorbid chronic diseases. In order to prevent elderly people with diabetes from visiting emergency room, it is important to encourage moderate-intensity activity and walking.

This study investigated the changes in the antioxidant activity, nitrite scavenging activity, and ��-glucan content of processed raw materials (Pleurotus eryngii, Pleurotus ostreatus, Lentinula edodes, and Flammulina velutipes) brought about by storage at room temperature (20-25℃) and low temperature (4℃). The results indicated that DPPH free radical scavenging activity was the lowest in air-dried and roasted samples that were stored at room temperature, k with the exception of the air-dried samples of P. eryngii and L. edodes. For total polyphenol contents, all roasted samples of the edible mushrooms stored at room and low temperature decreased compared with the samples pre-storage, except for the air-dried samples of P. eryngii, P. ostreatus, and L. edodes. Furthermore, the ferric reducing antioxidant power and reducing power of the air-dried and roasted samples stored at room temperature and low temperature tended to increase compared to that before storage. Moreover, the ��-glucan content in the air-dried and roasted samples stored at room temperature was significantly lower compared to that before storage, as well as to that in the samples stored at low temperature (p<0.05). The results of this study may help predict the degree to which biological activities in processed edible mushrooms change when stored at room temperature and/or low temperature conditions.

Background: To protect the public from natural radioactive materials, the 'Act on safety control of radioactive rays around living environment" was established in Korea. There is an annual effective dose limit of 1 mSv for products, but the activity concentration limit for products is not established yet. Materials and Methods: To suggest the activity concentration limits for consumer goods containing NORM, in this research, we assumed the "small room model" surrounding the ICRP reference phantom to simulate the consumer goods in contact with the human bodies. Using the Monte Carlo code MCNPX, we evaluate the effective dose rate for the ICRP reference phantom in a small room with dimension of phantom size and derived the activity concentration limit for consumer goods. Results and Discussion: The consumer goods have about 1600, 1200 and $19000Bq{\cdot}kg^{-1}$ for $^{226}Ra$, $^{232}Th$ and $^{40}K$, and the activity concentration limits are about six times comparing with the values of building materials. We applied the index to real samples, though we did not consider radioactivity of $^{40}K$, indexes of the some samples are more than 6. However, this index concept using small room model is very conservative, for the consumer goods over than index 6, it is necessary to reevaluate the absorbed dose considering real usage scenario and material characteristics. Conclusion: In this research, we derived activity concentration limits for consumer goods in contact with bodies and the results can be used as preliminary screening tool for consumer goods as index concept.

Purpose: To analyze the frequency of emergency room visits according to socioeconomic factors of emergency room visitors. Methods: In this study, frequency analysis, percentage analysis, and x² test were performed using the SPSS 23.0 program based on the 2018 data from the Korea Health Panel. Results: Among 1,648 participants included in this study, 1,279 visited the emergency room only once in the past year, while 369 visited the emergency room more than once. The relationship between frequency of emergency room visits and socioeconomic factors was analyzed using x² test, and no statistically significant relationship was noted between emergency room visits and education, economic activity, insurance type, and individual quartile income. However, a significant relationship was noted between emergency room visits and being handicap and living in households with quintile income. Conclusion: The study determined the relationship between frequency of emergency room visits and socioeconomic factors. A follow-up study analyzing socioeconomic factors of outpatient departments, 119 ambulance transport services, and frequency of emergency room visits among chronically ill patients is needed to provide basic data for establishing health policies among different socioeconomic strata.

The Educational Cultural Center for Students is a new mixed-cultural space which made around 1997 for students' education of humanism and talent with the 7th revision of educational course. This Educational Cultural Center for Students is different to the existing one because the subject of the culture is students who make creation and performance by themselves while the former ones were for seeing, hearing and feeling things. There are seven Educational Cultural Center for Students all over the country and will be built more in the future. Comparing to the former Educational Cultural Centers for Students, functional rooms in the Educational Cultural Centers for Students are an outdoor performance room, a large performance room, a small performance room of performance facility, a gallery of display facility, a gymnasium, a swimming pool, a fitness room, a table-tennis room of physical facility, a library and a reading room of a book facility, and a group room, a computer room, a singing room, a billiard room, an art room, a musical room, a dancing room, a manner room, a playing room, a cultural lecture room and a seminar room of a interest-activity facility. The result of analyzing the usage frequency is that a performance room has the highest frequency and a display room, a musical room, a music appreciation room and a physical room follow the frequency order. But this frequency does not fit for all area. By place and social situations, the frequency and space organization may be changed.

The purpose of this study is to grasp spatial effects of colours in interior design. The visual feeling in the 1/10 living room scale models that are different in the colour combination of ceilings, walls and floors is judged using a semantic scale of the fifteen adjectives. The major findings are as follows; 1) As a result of factor analysis, three dimensions, "evaluation", "activity" and "warmness" are extracted. Dimension 1, "evaluation", is most greatly affected by the chroma and hue of the room colour, dimension 2, "activity", by the hue and value, by the difference in hue and value of ceilings, walls and floors, dimensions 3, "warmness", by mainly the hue of the rooms. 2) Concerning the spatial effects of colour, the subjects felt higher vlaue with relevance to the hue of GY, Y, low chroma and high value. The room colours other than walls is felt more comfortable in similar colour, especially hue and value.re comfortable in similar colour, especially hue and value.

The aim of this paper is to find out different preference of common spaces and shared activities in senior cohousing community between regions in Korea: Seoul and other cities. Social survey was conducted nationwide and the respondents were 50s only, since they are the generation who will face to elderly housing subject within 10 years in turbulent Korean society. Collected data, about 1000, were analyzed by SPSS program using frequency, percentage, and Chi-square test. In summary, respondents mostly would like to move to senior cohousing on circumstance when they remain alone without big difference between regions. Loneliness and housekeeping were considered as the most difficult issues for the elderly to manage by themselves. Among common spaces, exercise room was the most preferred space to meeting room and kitchen. Exercise room was more preferred in Seoul than in other cities, on the contrary meeting room was evidently less preferred in other cities than in Seoul. Regarding shared activities, resident meeting, gardening, and common meal were revealed as less preferred activities than hobby exercise and tea meeting. As a conclusion, I would like to propose that a big common living room is better to be designed for meeting room cum dining and gathering room with flexibility in order to give residents chances to know each other more often. And since common space and shared activity show different preferences by regions, those are to be designed and planned reflecting region's different circumstance.

To isolate natural antihypertensive substances from edible seaweeds, we screened for and separated active compounds contained in natural Underia pinnatifida, cultural Underia pinnatifida, Laminaria japonica, Sporophylls and Agarum cribrosum. They were extracted using room temperature water, boiling water, acetone, and methanol in turn or using room temperature water, ether, acetone, methanol and boiling water in order. The in vitro antihypertensive activity was quantified as inhibitory efficacy against angiotensin-I converting enzyme (ACE), which is a factor inducing hypertension. For all of the seaweeds tested, the fractions soluble in room temperature water and in boiling water showed the strongest ACE inhibitory effect among the extracted fractions. Conversely, the methanol-extracted fractions for all of the seaweeds tested showed no antihypertensive activity. While the ether and acetone fractions had slight antihypertensive effects. The compounds in the aqueous extracts that had antihypertensive activity were presumed to be polysaccharides, such as fucoidan and alginate.
