The purposes of this study were to investigate the actual state of indoor air quality in semi-underground multi-family housing units in early summer, to analyze the influencing factors, and to make suggestions for improvement. A series of field investigations were conducted in four target units between June 22, 2010, and June 28, 2010. The field investigations included measurements of indoor air quality as well as the observation of architectural characteristics and living conditions. In addition to the field investigation, on-site questionnaire surveys were administrated to residents in 90 units. The findings are summarized as follows: (1) The average $CO_2$ levels in each of the four units ranged from 759ppm to 1885ppm. $CO_2$ levels in three units exceeded the evaluation standard (1000ppm), and one unit was lower than the standard. This unit had smaller number of staying person and a large amount of ventilation than others; (2) the average CO levels in each unit were almost 0ppm, but 0.1~1.1 levels of CO were revealed at several times; (3) the average PM-10 levels ranged from $8{\mu}g/m^3$ to $40{\mu}g/m^3$, which distributes within the standard ($150{\mu}g/m^3$). The influencing factors of PM-10 levels were analyzed as inflow from outside, the use of a gas range, and the residents' activities; (4) therefore, it was evaluated to be necessary to improve ventilation for the indoor air quality of semi-underground housing in aspect of $CO_2$ levels.

The purpose of this study is to propose a management method to maintain the pleasant indoor air quality of the dental clinic by measuring and analyzing the indoor air quality of the dental clinic. The measurement was conducted in two rooms, a lobby where many residents stay in the reception room for waiting for medical treatment, and a VIP room where treatment activities are mainly performed. Measurement items are Temperature, Humidity, $CO_2$, CO, $NO_2$, $CH_2O$, VOC, $PM_{10}$ and measurement were taken on April 27, 2018. As a result of analyzing the temperature and humidity of the dental clinic, it was analyzed that the average indoor temperature was maintained at $25^{\circ}C$ and the humidity was kept at around 50%, maintaining proper indoor temperature and humidity environment. $CO_2$ was 855ppm in the VIP Room, which satisfied the maintenance standard. In the case of the lobby, it was analyzed to be 1,160ppm, which exceeded the maintenance standard and it is judged that the carbon dioxide generated by the respiration of the people staying in the lobby is the main reason. The mean concentration of formaldehyde in the VIP room was analyzed as $436{\mu}g/m^3$, exceeding the maintenance standard, and $2,100{\mu}g/m^3$ for the VOC exceeded the recommended standard. It was analyzed that the concentration was relatively higher due to the use of disinfectant and other drugs. The mean concentration of PM-10 in the lobby was analyzed as $65{\mu}g/m^3$ and it was analyzed that it satisfied the maintenance standard. To maintain a pleasant indoor air quality in a dental clinic it is necessary to minimize the effects of formaldehyde, VOC, $CO_2$ in the VIP rooms and lobby. For this purpose, the entire ventilation system and air purification system of the dental clinic should be installed. In case of the VIP room, local exhaust ventilation should be installed and workers should wear personal protective equipment.

In order to analyze the impact of fine dust generated from a construction waste intermediate processing site on the surrounding areas, diverse types of samples were collected from inside the site and surrounding areas. The impact analysis results of samples are as follows. (1) Compared to the air quality management standards by the Ministry of Environment, the concentration of fine dust within the site was 30 to 46% for PM10 and 14 to 42% for PM2.5, which was not much different from the general air quality level. (2) It was found that PM10 within the site may have a partial effect on the air quality, but when the blocking facilities in the site, wheel washing facilities at vehicle entry and exit route, and sprinkler during working were maintained, the impact on the nearby area was not high. (3) In the case of PM2.5, its concentration was influenced more by the exhaust fumes from work vehicles than fine dust generated during construction waste processing. Since the PM2.5 concentrations in the site and surrounding area were not much different from the general air quality, there was little correlation with the work impact of construction waste intermediate processing sites. (4) Pb, an indicator of heavy metal components, was within 50ng/m³ in all three sites, which was 10% of the domestic management standard and equivalent to the general air quality level. The complaints from residents in nearby areas were filed using indicators based on visual and experiential information in their daily lives, so even if the survey results of environmental impact by the construction intermediate waste processing site are lower than the standard, nearby residents can feel it better than such numerical information. Therefore, specific activities to reduce find dusts should be continuously continued.

This study investigated the physicochemical and sensory characteristics of white bean paste prepared with various amounts of aronia powder (as ratios of 0%, 2%, 4%, 6%, 8%, 10%). The result shows that the pH of white bean paste decreased significantly with the addition of aronia powder. From chromatography, the brightness, L-value was decreased by increasing the adding rate of aronia powder. The a-value of sample group adding 2% of aronia powder was the highest and that of sample group adding 8% was the lowest (p<0.01). Sample group adding 8% of aronia powder achieved the highest appraisal from many factors, such as springiness, cohesiveness, chewiness, brittleness, and adhesiveness. The total polyphenols and anthocyanin contents were proportionally increased with increasing the level of aronia powder added in white bean paste. The antioxidant activity measured by DPPH and NSA radical scavenging activities was significantly higher than control and increased proportionally to the aronia powder concentration. The result of sensory test shows that sample group adding 6% of aronia powder achieved the highest. Based on the above results, this study suggests that the addition of 6% aronia powder may be the best substitution ratio for white bean paste of the improvement of sensory preference and antioxidant.

Purpose: This study aimed to determine the effect of curved walking training on balance confidence and fall efficacy in early stroke patients. Methods: The study included 16 early stroke patients who were randomly allocated to a curved walking training group (experimental group, N=8) and a straight walking training group (control group, N=8). Both groups performed the exercise 5 times a week for 3 weeks. Outcomes were assessed using the Activities-specific Balance Confidence (ABC) Scale, Fall Efficacy Scale (FES), Berg Balance Scale (BBS), and Timed Up and Go (TUG) test. Results: After 3 weeks of training, both groups showed significantly improved ABC, FES, BBS, and TUG (p<.05 in both groups). However, the ABC, FES, BBS, and TUG scores in the experimental group were significantly better than those in the control group (p<.05). Conclusion: These findings indicate that curved walking training may be effective at improving balance confidence and decreasing fall risk in early stroke patients. Therefore, curved walking training can be used as a recommended walking method in early stroke patients.
