Background: Community ambulation has been recently recognized as one of the most essential factors of activities of daily living in patients with post-stroke hemiparesis. This study aimed to compare walking velocity and step number in 5 community situations in patients with post-stroke hemiparesis. Methods: Ten chronic stroke patients volunteered for this study. The main variables analyzed were walking speed and step number, and these were measured in 5 different community situations: a physical therapy room, a parking lot, a bank, a crosswalk, and a hospital lobby. The measurements obtained for walking in the physical therapy room were measured using a 10m walk test and were used as baseline data for comparison with each option. The ambulation distance was set at 300m for the parking lot and the bank and 150m for the crosswalk and hospital lobby. For data analysis, walking speed and step number were standardized with the distance options of each ambulation. Results: Compared to the walking speed in the physical therapy room, those in the other situations, except for the parking lot, were significantly different (p<.05). Moreover, there were significant differences in the speeds between the bank and the parking lot and between the parking lot and the crosswalk (p<.05). Compared to the step number in the physical therapy room, those in all situations except for the crosswalk were significantly different (p<.05). Further, there was a significant difference in the step number between the bank and the crosswalk (p<.05). Conclusion: The walking ability of patients with hemiparesis in real environments within a community could be different from that in a physical therapy room. Therefore, the evaluation of walking should be performed in a variety of community situations.

Fuji and Jonathan apples were stored at cold room and at CA storage conditions of $3%O_2-2%CO_2$ for Jonathan and $4%O_2-3%CO_2$ for Fuji for 8 months, and then tranferred to air at $20^{\circ}C$, 70%RH to compare the some factors related to texture of the apples stored at different storage conditions during exposure at $20^{\circ}C$. Total pectin content and firmness of the apples reduced, considerably with concomitant increases of water-soluble pectin content and polygalacturonase activity during exposure at $20^{\circ}C$ after storage. And the changes were much more serious in the first 5 days than any other period and in the apples stored at cold room, especially in Jonathan than the apples stored at CA storage conditions. From the sensory test the apples stored at cold room maintained acceptable quality for 5days after removal from storage condition. The acceptability from the test was lenghtened for more than 5 days in Jonathan and more than 10 days for Fuji stored at CA storage conditions. when compared with those of the apples stored at cold room.

The purpose of this study is the extent of the stress of the nursing students during the period of delivery room practice, according to whether they have their practical experience and in which situations they received. The subject of this study is 62 nursing students (who experienced delivery room pracice at an early stage) in Kang Weon C. Junior College of nursing and 62 nursing students(who experienced delivery room practice at a latter stage) in J.Junior college of Nursing (total 124 students) from March 1988 to December 1988. The results of this study are summerized as follows. 1. According to the general characteristics, it revealed that they have not any relations between the religion, the numbers of family, health status and the extent of stress during the nursing students have experienced in the delivery room practice(p＞.05). 2. It revealed that there were much differences to the extent of stress they have experienced during the delivery room practice between the nursing students(who experienced delivery room practice at an early stage) in C.Junior College of Nursing and nursing students(who experienced delivery room practice at a latter stage) in J. Junior College of Nursing(p＜.000). 3. In ten items of the stress that was confronted by nursing practice, they had much differences to the extent of stress perception for the students during the period of delivery room practice between each college(p＜.05). 4. In the four parts of the clinical practice except for adult nursing practice, they had much differences to the extent of stress according to whether they have their practical experience. However the stress which they experienced in the adult ward during the period of delivery of delivery room nursing practice is too low to be significant(p＜.05).

The purpose of this study was to set up the objective standards of a space design for preschool children's room. In order to perform the above purpose, this study was organized into three sections. First, literature review to understand the relationship between preschool children's development and children's room, design elements and correlated variables of children's room. Second, survey research to seek a standard of children's room size, necessary furnitures, prefeerred colors and motifs. Third suggestions of objective and concrete alternative plan through the literature review and survey research. The major findings from the survey research were summarized as follows : 1) The mean size of contempory preschool children's room was 3.1 pyong and that of ldeal room was 4.7 pyong. 2) Necessary Furnitures with which more than two-thirds of parents want to furnish were bed, wardrobe, chest of drawers, toy shelves, toy boxes, book cases, chalkboard. Necessary furnitures for different ages were found to vary. For the age 2-5, the funitures for play were major, where as for the age 5-6, the furnitures for study were major. 3) The colors of contemporary preschool children's room were red, yellow, pink, blue, those of parent's favorites were Light colors(pink, skyblue, lemon yellow, Light green, Light purple). The rooms for boy were found with more cold colors, those for girl with more warm colors. 4) The motifs of contemporary preschool children's room were plants, lines, figures from cartoons of fairy tales. Boy's parents prefreerd space science and vehicles, while girl's parents preferred sky scenery and plants for their children's room.

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.

Indium tin oxide (ITO) films with a 5 nm thick Au interlayer were prepared on glass substrates. The effects of the Au interlayer on the gas sensitivity for detecting methanol vapors were investigated at room temperature. The conductivity of the film sensor increased upon exposure to methanol vapor and the sensitivity also increased proportionally with the methanol vapor concentration. In terms of the sensitivity measurements, the ITO film sensor with an Au interlayer shows a higher sensitivity than that of the conventional ITO film sensor. This approach is promising in gaining improvement in the performance of ITO gas sensors used for the detection of methanol vapor at room temperature.

Trend of mechanical ventilation system applied to apartment house is introduced and feasibility study on installation of the individual room control ventilation as energy-saving method is carried out through field experiment. While initial cost of installation for the individual room control ventilation increases, the running cost is lower than the individual household control ventilation due to automatic flow rate control and reduction of fan power, and the management cost also decreases due to extension of use life of components. As the results of field experiment on $115m^2$-type apartment house, the individual room control ventilation could save the amount of 1,459.5Wh/day when compared with the individual room control ventilation
