In this study, bacterial diversity in the living room and bathroom of a residential environment was analyzed using the pyrosequencing method. There was no difference in the diversity index of bacteria between the 2 rooms; however, differences were noted in the composition of bacteria. The classes ${\beta}$-Proteobacteria and ${\delta}$-Proteobacteria were found in the bathroom at higher abundances than in the living room. The phyla Acidobacteria, Chlorobi, Chloroflexi, Fusobacteria, Nitrospirae, and Planctomycetes were found in the bathroom, but not in the living room, indicating a broader range of bacteria. However, the living room showed a more diverse range of bacterial genera than the bathroom did. In both the living room and the bathroom, the genus Methylobacterium was dominant.

For guaranteeing for security of nuclear power plant, ergonomic factors have been applied to design of main control room, core area for management and control of nuclear power plant, but design elements for performance of operators have been ignored. As the behaviors of operators are important for security of nuclear power plant, space design which makes them pleasant psychologically and makes them maintain attention on security equipments ceaselessly is required. Therefore, the purpose of this study is to analyze space characteristics of main control rooms according to regulations of nuclear power plant and general guidelines of space design, and to offer basic data for designing of main control room which makes operators pleasant psychologically and physically. At first, theoretical issues related with design of main control room are reviewed and several premises of space are developed by abstracting design elements from common space and regulations of nuclear power plant and, then integrating each design elements interactively. In short, the improvement of system environment based on human-machine interface space has brought about perceptual, cognitive, and spatial changes and has realized next generation of main control rooms. And, differences and similarities between ordinary space and main control room, which ergonomic sizes and regulations are applied and is VDT environment based on LDP, are discussed in relation to 13 design elements and 17 space premise.

Acinetobacter is a bacteria found in the environment and clinical specimens, causing nosocomial infection and antimicrobial resistance (AMR) threats. This study examined the prevalence, species, and AMR characteristics of Acinetobacter isolated from surgical practice and the laboratory dog husbandry room environments (n = 235) at Rajamangala University of Technology Tawan-ok veterinary hospital during 2018-2019. The prevalence of Acinetobacter in the laboratory dog husbandry room and veterinary belongings were 2.55% and 0.43%, respectively. Species determination was Acinetobacter hemolyticus (2.13%) and Acinetobacter baumannii (0.43%) from environments in the laboratory dog husbandry room, and Acinetobacter junii (0.43%) from the shoes used in the surgical practice room. AMR was observed in both study environments and the specimens sent to the Veterinary Diagnostic Center. These isolates had a high resistant percentage to amoxicillin-clavulanic acid (84.62%), sulfamethoxazole-trimethoprim (61.54%), and cephalexin (53.85%) but were susceptible to imipenem. Compared to the isolates recovered from the clinical specimens, most isolates derived from environments exhibited multidrug resistance and shared correlated resistance patterns. These results highlight the need for sanitization in the dog husbandry room. Furthermore, the AMR results can be used as a preliminary baseline for studying AMR Acinetobacter contamination in animals and their environments.

The purpose of this study is to evaluate environmental characteristics of maternity rooms. The method of this study is a field survey on 8 samples of postpartum care centers in Seoul. The plan, colors, materials, furniture and environmental characteristics of maternity rooms are analyzed. The characteristics of maternity rooms environment were categorized into four items; comfort, privacy, communication and dwelling. The results are as follows: Western-style and rooming-separation system of maternity rooms are used. Maternity rooms are generally good for dwelling quality but insufficient for communication. There are a lack of supply to control a temperature Individually in maternity rooms. It demands to make the type of one-sided public space between maternity room and living room for privacy. All of the maternity rooms surveyed are furnished with TV, radio, and telephone but, to improve communication with visitors, it is recommended that more convenient supplies such as audio and video system, chairs, and table be equipped. There are needs for sky-light windows in maternity rooms. It is necessary to research more about the space of living room, nursing room and service area, and we need more study about baby, nurser and owner' spaces.

The primary purpose of a computer room of data center and associated infrastructure is to support the operation of critical IT equipment. Traditionally, most owners of large critical data centers have been more than willing to accept a reasonable amount of computer room worker discomfort if necessary to support critical IT systems. All electrical equipment produces heat, which must be removed to prevent the equipment temperature from rising to an unacceptable level. Most information technology equipment and other equipment found in a data center or network room is air-cooled. Sizing a cooling system requires an understanding of the amount of heat produced by the equipment contained in the enclosed space, along with the heat produced by the other heat sources typically encountered.
