To assess microbiological indoor air quality in schools, concentrations of viable airborne microorganisms were monitored at classrooms and corridors of 3 middle or high schools in Ulsan. Airborne microorganisms were sampled at various situations during a semester (class-hour, lunchtime, after school) and during a vacation with an impaction-type air sampler. During the semester, the number of bacteria was the highest at lunchtime in corridor with an average of $1,111\;MPN/m^{3}$ and lowest at class-hour in corridor with an average of $132\;MPN/m^{3}$. During the vacation, the bacterial concentrations at classrooms and corridors were only $5{\%}$ and $27{\%}$ of the values during class-hours of the semester, respectively. Among the colonies tested, $60{\%}$ were identified as relatively harmless Micrococcus species and $12{\%}$ were Staphylococcus species. During the semester, the average values of fungal concentrations at each situation ranged from 105 to $213\;MPN/m^{3}$, and the values during the vacation were $32\;MPN/m^{3}$ at classrooms and $83\;MPN/m^{3}$ in corridors. Fungal genera such as Cladosporium, Penicillium, and Aspergillus were identified from the colonies. The obtained data can be considered as a step to set a guideline for bioaerosols in indoor environment of schools.

Clothes for a 3 to 6 year-old toddler should be made in consideration of their behavioral characteristics since it is when the physical ability of toddlers has rapidly developed and their social, emotional, and cognitive development are increasingly active. Indoor clothes are the item that consumers prefer because they provide the function of outside underwear when functioning as outerwear when indoors that is used frequently for toddlers. We analyzed the wearing condition and the uncomfortable aspects of toddler's clothes worn indoors through consumer surveys of toddler wear. This study gathers data for the development of indoor clothing that is useful for 3-6 year old toddlers. Consumer surveys indicate that the clothes most worn indoors were underwear (69.4%). The most important aspect in the selection of indoor clothes was the suitability for activities (29%). The preferred colors for indoor clothes were found to be pastel-tone colors (66%). Regarding the uncomfortable aspects of indoor clothes, knees of the clothes (36.8%) have the most naps and the breast of the clothes (37.8%) dirty quickly. Knee parts (35.4%) become worn easily; in addition, the material for the knee area is likely to have naps and require special functions. In conclusion, designing toddler clothing requires elaborated design techniques that consider the characteristics of the subject group and reduce inconveniences. This study will serve as preliminary data to develop ultimate products that have the functionality to meet gender behavior characteristics and the aesthetics for toddlers 3 to 6 years of age.

This article analyzed the recent Korean accessibility standard supporting the people with disabilities. This is the basic study to make the interior environment more comprehensible and safer for the physically handicapped. Researcher selected the interior elements related to the mobility and accessibility for the physically handicapped. Then the '98 Korean accessibility standard code called 'Pyunui Chungjin Pup' were compared with the previous Korean building code and two other guidelines for evaluations. Result showed that 'Pyunui Chungjin Pup' addressed more obligatory items in facilities used by people with disabilities. That contributed to develope the accessible environments and to offer the independent activity in the society for the disabilities. However dimensions of 'Pyunui Chungjin Pup' showed the minimum standard. Also it did not provide the sufficient design considerations to make up the sufficient design considerations to make up the other types of disabilities including sensory limitations, or cognitive function limitations. Hereafter, the quality of accessibility guideline should be raised with further study.

Recently, as the demand for transmission of ultra-high quality media data such as UHD, AR, and VR increases, various technologies for this have been actively developed and IEEE 802.11ad standard have been commercialized. In this paper, a test bed is constructed to analyze the indoor wireless environment using the IEEE 802.11ad standard based on mmWave, and the experimental results of various indoor wireless environments are introduced and analyzed. We compared the data from the module by data transmission, such as signal to noise ratio(SNR) and throughput. And we measured the beam pattern and width of the module and compared the effects on the indoor environment of the corridor and the office. This shows that the signal reflection of the wall shows higher SNR values and is more suitable to use for indoor than outdoor. It is confirmed that the loss when not in line of sight(LoS) is not enough to compensate the wall reflected signal. As a result, it is judged to be suitable for the indoor use of the mmWave LAN and can be usefully used for further experiments.

In this paper, the technique of prediction and analysis on the characteristics of propagation in indoor environment is presented. This technique needs no reception sphere commonly used in 3D-ray tracing scheme, and thereby it lends us easy code realization. The validity of developed code is verified by comparing with the values of image methods and measurement. The developed technique applied to the structure of rectangular corridor with the iron door and we calculated the path loss for the variation of the iron door angle. The path loss decreased about 15 dB at the distance of30 m from the iron door and the delay spread increased approximately by four times. Based on the computation, we confirmed that indoor propagation in PCS is heavily affected by the iron door in corridor.

This study was intended to develop some lounge wear ensembles of emotional design by using an eco-friendly material, Kenaf fabrics in line with the contemporary trend of valuing health and environment. With market survey on commercially available indoor clothing ensembles in the market, the designs of lounge wear ensembles being on sale via on/off-line routes were analyzed. Provided by Korea High Tech Textile Research Institute, Kenaf fabrics were employed to make 4 pieces of lounge wear for women (cardigan, T-shirt, slacks, vest) and 4 ones for toddlers. In addition, some housewives in their thirties or forties who lived in Seoul were asked to respond to a series of questionnaires concerning the prototypes made directly in order to evaluate consumer satisfaction with them. Although the consumer awareness of Kenaf fabrics is very low as far, this attempt to present the designs of lounge wear made of Kenaf to young housewives who have a lot of concern for and purchase experiences of eco-friendly materials is meaningful in the light of the possibility to popularize Kenaf which is not familiar as a textile material yet.

The purpose of this research is to investigate elderly, middle-aged female consumers' design and material preferences for lounge wear and after understanding senescent women's propensity to purchase lounge wear. The subject of research were to those living in the Seoul and capital region and 612, which did not comprise missing values, were collected and used for data analyses. All the age groups including those in their 50s and 60s prefer jacket and pants styles the most and these styles are the most favored as lounge wear as well. Those in their 50s and 60s prefer a round neckline the most while those in their 70s favor a V neckline the most. Analyses of sleeve styles of senescent women show that all the age groups favor a straight set, or a sleeve design, the most. Although the aged people investigated in this research have relatively high purchasing power, it is found that they tend to buy low priced lounge wears. Reviewing all of the above-mentioned results, the prices of garments for senescent people will be set in consideration of their economic level, so that good quality commodities may be produced and sold at different prices.

Buildings undergo changes by various factors according as pass at time. Due to that social requests and issues form one common sense of value and this would influence the architect's design intention. In fact, the form and function of buildings have coped with transition of the common sense of value by each times. Hospital architecture is also changed in function, scale and technology since, Kwanghyewon which was the first western style hospital in Korea was established in 1885. It is changing that the social needs for hospital which was a basic function of healing to laying emphasis on the function of precaution. According to this, the change of hospital spaces means that it can promote healing environment which is expanded from the modern concept of isolation, accommodation and urban sanitation. These changed concepts were adopted limited areas in hospitals at first however, nowadays they are expanding to other areas. So, this is caused to make the image of the hospital. From this point of view, Entry space is an example to show the changes. This study is intended to determine the overall space structure of entry area and to classify and analyze the difference.
