This study investigated the sitting areas preferred to use by assisted living residents in the U.S., compared the perceptions of staff and residents, and analyzed the effects of residents' and spatial characteristics on the preference for use of main sitting areas such as lounge, dining area, activity room and outdoor area. A total of 102 participants(66 residents and 36 staff) from eight facilities in the seven counties of southern Texas were asked about two sitting areas residents like to spend time at. The results of the study were as follows: The most frequently mentioned sitting areas were the activity and outdoor area as per the residents, but the dining area and lounge as per the staff. It might be due to that the view of staff might have been limited to sitting areas usually used by the severely frail residents. Residents using higher level of mobility assistance such as wheelchairs and walkers, or living in the facility having more dispersed sitting areas were less likely to prefer to use the lounge. The residents who were younger or having good centralized outdoor area were more likely to prefer to use the outdoor area. The preference for use of dining area was affected by its proximity from the residents' individual rooms. Diverse survey methods need to be developed for a more in-depth collection and analysis of data from functionally frail older residents and staff caring for them.

As the number of children's libraries has increased in Korea, it has been discussed to improve the quality of design in the libraries. In a reading room of children's library, spatial consideration should be focused on the children under 10 years old since they are in important points to learn Hangul and to develop reading habits. This study is aimed to examine the characteristics of a floor-sitting reading room, where children can feel like a home, stay in clean and safe and play while reading. The seven case studies of floor-sitting reading rooms are analyzed from the viewpoint of each factor of physical environment, including structure, furniture, and decoration. The following is the summary of findings of this study. First, floor-sitting reading rooms tend to compose main reading areas around bookshelves. Reading areas create the characters by changing floor levels and arranging furniture associated with windows, columns, and wall-type bookshelves. In the reading areas, movable low-level tables are frequently placed for flexible space uses, and seats for reading tend to put together with fixed bookshelves. Second, the central areas of the reading rooms are often shaped in the forms of pods, storytelling areas, sculptures, and unique furniture. Especially storytelling areas and pods play the cores of the reading rooms with the varying steps of floors and pictorial graphics on walls. Third, decoration elements in the reading rooms are designed with graphics, visual displays, and sculptural decorations. In my case studies, spatial elements such as reading nooks, attics, tunnels, and shelters are not often found in the floor-sitting reading rooms even though children like to have them. Since it is the advantage of floor-sitting reading rooms where children can take off shoes and act freely, we should look for the design of such spatial elements in the floor-sitting reading rooms.

This study investigated residents' preferences for spatial features of sitting areas in assisted living facilities, and provides recommendations for planning sitting areas to support residents' spatial preferences and social interaction. The study participants were 69 residents of eight assisted living facilities (30+ resident capacity), located in south central Texas. A photographic comparison method was used, in which residents were shown 20 matched pairs of photos, with a single feature digitally modified in each pair, and asked to select which environmental representation they preferred. The hypothesized spatial characteristics were identified in practice based literature as those that may encourage usage of sitting areas: viewability, variety, homelikeness, and privacy. Most of the hypothesized features were preferred by participants, with the highest preference found for non-institutional furniture arrangements and naturalness, followed by increasing enclosure and variety of seating. Preference was less significant for domestic cues such as carpeted floors, divided light windows, and boundaries defined by different colored material or columns, possibly due to their physical impairments or preference for visual openness. Participants' level of mobility assistance was significantly related to their preference for some features, such as seating with people-watching capability, and carpeted floors. The findings have implications for facility architects and administrators engaged in resident-oriented spatial planning.

퇴계의 거경 공부는 정좌와 독서라는 실제적인 방법 속에서 더욱 효과적으로 발현되었다. 그는 주자에 비해 정좌의 형식을 더 중시했는데, 그 중에서도 위좌(危坐)의 형식이 더욱 강조되었다. 정좌와 독서는 퇴계가 가장 즐겨 행한 실천 방법이었다. 그러나 정통 주자학의 입장과 다르지 않게 퇴계는 정좌와 독서가 하나의 목적이나 유일한 방법이라고 주장하지 않았다. 공부의 궁극적인 목표는 나 자신의 편벽된 기질을 변화시키고, 의리를 궁구하고 마음을 함양하며, 사물을 대하는 데 있어서 절도에 맞게 행동하는 것이었다. 이밖에 퇴계는 심신의 수련과 치료, 그 중에서도 특히 육체의 질병을 치료하고 원기를 회복하는 차원에서 부분적으로 도인술을 활용했다. 퇴계의 기록들로 볼 때, 그는 적어도 안마법과 호흡법에 정통했다고 말할 수 있다. 퇴계의 공부론은 주자 공부론에 비해 형식적인 면이 강조된 측면이 있고, 거경의 공부가 더 광범위하게 해석되어 적용된 측면이 있으며, 도인술과 같은 비정통적 공부론을 배격하지 않고 부분적으로 도입하여 보완적인 요소로서 활용한 데서 그 특징을 찾을 수 있다.

The purpose of this study was to investigate the effect of age on the human thermoregulatory responses and to obtain the basic information of the Korean thermophysiological characteristics under the traditional Korean floor heating system-Ondol. The participants consisted of 10 elderly women, 4 elderly men(over 65 years), 10 young women and 5 young men(in twenties). They were exposed to temperature-controlled Ondol room(20$\pm$1$^{\circ}C$, 50$\pm$5%R.H., floor surface temperature: 30$\pm$1$^{\circ}C$) for 60 minutes and wore the same experimental clothing. The postures were performed sitting and supine on the floor. In each pose, rectal temperature, skin.temperature of 10 areas, mean skin temperature, clothing microclimate, body fat were measured. The results were as follows; 1. The rectal temperature gradually decreased and mean skin temperature gradually increased in young and old groups in both supine and sitting pose on heated Ondol floor for 60 minutes. 2. Rectal temperature was different in each pose. The rectal temperature decreased 0.1$^{\circ}C$ in both groups under the condition of sitting and decreased 0.2'c in elderly group under the condition of supine. In supine pose, elderly group was more declined than young group. Mean skin temperature increased 0.5$^{\circ}C$ in both poses, both groups.

The aim of this study was to establish the basic data on anthropometric characteristics of Korean farmers in a sitting posture. 533 Korean farmers(Male: 236persons, Female: 297persons) volunteered for this study from 8 different provinces nationwide in 2010. Subjects were classified according to their sex and categorized into 4 age groups from 40s to 70s and over. Statistical tests such as descriptive analysis, independent t-test, one-way and two-way ANOVA were conducted to analyze the data. The results were as follows: Korean farmers generally edged toward obesity. The older the farmers were, the smaller their body sizes were, but fatter in the abdominal areas. There were significant differences on the waist-related measurement items between farmers and the public. The farmers' waist-related sizes were larger than that of the public of all age groups in the male group, but only the forties age group in the female group. It tended to differ according to sex and age groups that we analyzed from the measurement values on other items between farmers and the public.

This study was done to investigate thermal reponses and to obtain the basic information of thermal comfort by sex and posture under the Ondol heating system. Six healthy males and females were exposed to Ondol(Room Temp.: 25$\pm$1$^{\circ}C$, 50$\pm$10%R.H, Floor Temp.:30$\pm$1$^{\circ}C$) on the of posture such as sitting, lying aside and supine on the floor for 30 minutes after 30 minutes' control phase. During the experiment, rectal temperature, skin temperature of 10 areas, local sweating rate, clothing microclimate, subjective sensation were measured. Rectal temperature gradually decreased and mean skin temperature grad-ually increased both male and female in any posture. There was not significant difference between male and female in rectal temperature and mean skin temperature. There were significant difference among the postures in rectal temperature(p<0.001) and mean skin temperature(p<0.001). In lying aside and supine on the floor, appearances of change and changes in rectal temperature and mean skin temperature were large, changes of weight were small. In sitting on the floor, appearances of change and changes in rectal temperature and mean skin temperature were small, changes of weight were large. The trunk skin tem-perature was higher in female than in male, but the extremity skin temperature was higher in male than in female. In sitting on the floor, foot skin temperature(p<0.001) was higher than any other local skin temperature. In supine on the floor, back skin temperature(p<0.001) was higher than any other local skin temperature.

This paper is to clarify a thermal physiological index that can account for the effects of local thermal environment. For this purpose two young female subjects exposing themselves to the above while sitting on a chair, sitting on the floor and lying on the floor were measured. These three representative postures accompanied the different contact surface areas, thereby the heat conduction rate between the floor and subject was quantitatively measured for each posture. It made the present study deal with the effect of heat conduction concerning the modified mean skin temperature and finally propose new weighting coefficients for the mean skin temperature calculation based on the Hardy & DuBois' formulas. In order to verify the proposed model, the experiment was carried out using a floor heating system. The comparison between the experimental result and prediction revealed that the proposed model should be about 10% more accurate than the conventional one in the case of lying on the floor which the heat conduction effect becomes important.

This study is a preliminary research to develop design principles for environmentally friendly housing. The purposes of study are to investigate the literatures related passive design for summer and theory of ventilation, to analyze the indoor airflow patterns in traditional Korean house during summer, and to propose the design factors for effective passive cooling system. The analysis for airflow patterns was focused on the ‘An bang’and the ‘Dae Chung’in the ‘An Chae’of a traditional house located in Seoul. Field measurements of air temperature and air velocity were carried out at 30 different measuring points with 8 different window-opening conditions. The measurements were taken on the hottest summer days in August 2000. It is concluded that from an environmentally friendly standpoint design factors to control indoor thermal environment by a passive cooling system during the summer are as follows; ceiling structure has thermal performance like a time-lag effect, optimum height and length of eaves which can prevent sunlight and divert airflow toward the sitting level, building arrangement acceptable the prevailing wind, strategic window arrangement which makes cross ventilation possible (especially north-south) at the sitting level, window opening condition which is possible to intersect two cross-ventilation stream at the main living areas, northward windows remaining in shade to create the air pressure difference, and planning building shape like a bracket that has optimum width and depth.
