In recent decades, the majority of studies have concentrated on the utilization of Steel Square Hollow Section (SHS) columns, with minimal attention given to reinforcing columns exhibiting inherent defects. This study addresses this gap by introducing initial vertical and horizontal defects at three distinct locations (top, middle, and bottom) and employing Carbon-FRP for reinforcement. The research investigates the dimensional and positional impacts of these defects on the axial behavior of SHS columns. A total of 29 samples, comprising 17 with defects, 11 strengthened, and 1 defect-free control, underwent examination. The study employed ABAQUS modeling and conducted experimental testing. Results revealed that defects located at different positions significantly diminished the load-bearing capacity and initial performance of the steel columns. Axial loading induced local buckling and lateral rupture, particularly at the defect side, in short columns. Notably, horizontal (across the column's width) and vertical (along the column's height) defects in the middle led to the most substantial reduction in strength and load-bearing capacity. The axial compressive failure increased with the length-to-width ratio of the defect. Moreover, the application of four carbon fiber layers to strengthen the steel columns resulted in increased Energy Dissipation and a delayed onset of local buckling in the face of axial ruptures.

Despite the acknowledged benefits by incorporating daylighting in the lighting system of office buildings to enhance energy efficiency and ensure occupants' well-being, a significant gap in understanding the integration of daylighting control system (DCS) with Building Information Modeling (BIM) exists, which can lead to improved energy efficiency and enhanced building design, specifically regarding the impact of daylight on occupant comfort. Previous studies have highlighted the potential of BIM to revolutionize both architectural design and building performance. However, an untapped potential of BIM in facilitating daylighting control in office areas is yet to be explored. The significance of this study lies in prioritizing occupants' well-being and enhancing building performance. This research identifies the feasibility of BIM-enabled DCS through a literature review from three perspectives: BIM-enabled DCS and daylight strategies, BIM-assisted façade system improvement, and user-centric daylight utilization within BIM platforms. As for results, a sensor network diagram illustrating network structure, data flow, and connections between devices of BIM enabled daylight control system for office buildings are established. Additionally, a BIM assisted daylight control strategy diagram is presented to outline user-centric control facilitated by BIM platform. In terms of contribution to the body of knowledge, this research will provide a comprehensive synthesis of existing literature in this domain. Additionally, this research could provide architects, DCS designers, and sustainable building professionals with potential advancements and inspirations to promote energy-efficient and user-centric building design in the future.

A pathogen that causes a new disease on green pumpkin in the nursery and the field was characterized and identified. Symptoms of the disease on green pumpkin were water soaking lesions and spots with strong yellow halo on leaf, brown lesion on flower, and yellow spot on fruit. The bacterial isolates from the leaf spot were pathogenic on the 8 curcubitaceae crop plants, green pumpkin, figleaf gourd, wax gourd, young pumpkin, zucchini, cucumber, melon, and oriental melon, whereas they did not cause the disease on sweet pumpkin and watermelon. They were Gram-negative, rod shape with polar flagella, fluorescent on King's B agar and LOPAT group 1a by LOPAT test. Their Biolog substrate utilization patterns were similar to Pseudomonas syringae pv. syringae's in Biolog database. Phylogenetic trees with 16S rRNA gene sequences and multilocus sequence typing (MLST) with nucleotide sequences of 4 housekeeping genes, gapA, gltA, gyrB, rpoD and those of P. syringae complex strains in the Plant Associated and Environmental Microbes Database (PAMDB) showed that the green pumpkin isolates formed in the same clade with P. syringae pv. syringae strains. The clade in MLST tree was in the genomospecies 1 group. The phenotypic and genotypic characteristics suggested that the isolates from green pumpkin lesion were P. syringae pv. syringae.

The progress of data transmission technology through the Internet has spread a variety of realistic contents. One of such contents is multi-view video that is acquired from multiple camera sensors. In general, the multi-view video processing requires encoders and decoders as many as the number of cameras, and thus the processing complexity results in difficulties of practical implementation. To solve for this problem, this paper considers a simple multi-view system utilizing a single encoder and a single decoder. In the encoder side, input multi-view YUV sequences are combined on GOP units by a video mixer. Then, the mixed sequence is compressed by a single H.264/AVC encoder. The decoding is composed of a single decoder and a scheduler controling the decoding process. The goal of the scheduler is to assign approximately identical number of decoded frames to each view sequence by estimating the decoder utilization of a Gap and subsequently applying frame skip algorithms. Furthermore, in the frame skip, efficient frame selection algorithms are studied for H.264/AVC baseline and main profiles based upon a cost function that is related to perceived video quality. Our proposed method has been performed on various multi-view test sequences adopted by MPEG 3DAV. Experimental results show that approximately identical decoder utilization is achieved for each view sequence so that each view sequence is fairly displayed. As well, the performance of the proposed method is examined in terms of bit-rate and PSNR using a rate-distortion curve.

This study analyzed the level of digital informatization and the level of human relationship satisfaction in the disabled group. The digital informatization level of the disabled refers to the level of smart access, smart capability, and smart utilization. For the sampling of persons with disabilities, the survey was conducted for persons aged 7 to 69 who were registered under the Welfare for Persons with Disabilities Act. Regression analysis utilized SAS 9.3.s through vitalization of local communities, and information education for the disabled is also important. The analysis results are as follows. First, the higher the digital access level of the disabled, the higher the level of interpersonal satisfaction. Second, the higher the digital information capability level of the disabled, the higher the level of interpersonal satisfaction. Third, the higher the level of digital information utilization of the disabled, the higher the level of interpersonal satisfaction. As a result, the higher the digital information level of the disabled, the higher the satisfaction level in the interpersonal relationship of the disabled. In addition, it was found that careful attention and policy review are needed to resolve the digital information gap of the government for the disabled who are marginalized groups. Therefore, it is necessary to provide the expansion of universal services of the marginalized groups including the disabled. In addition, it is important to form a culture in which the community embraces the marginalized class through vitalization of local communities, and information education for the disabled is also important.

The effects of regional medical insurance on utilization of medical care in urban population was examined in this study. The data was collected in a 2-year follow-up household survey conducted at Taegu city before and after implementation of the regional medical insurance. The study population was divided into 2 groups. Cohort I was the uninsured in 1989 and cohort II was the insured in 1989. After the coverage of medical insurance, physician visit rate per 1,000 population, use-disability ratio and use-restricted activity ratio in cohort I were increased compared to cohort II in both of acute and chronically ill people. The use-disability ratio and use-restricted activity ratio of the insured poor were lower than those of the insured nonpoor in both of cohort I and cohort II. The major reasons for pharmacy use were accessibility and affordability before the coverage of medical insurance in cohort I, however, after the coverage of medical insurance, the important reason was accessibility rather than affordability. In logistic regression analysis of physician visit, the significant independent variables were acute illness episode (+), chronic illness episode (+) and income (+) in both of cohort I and cohort II. In cohort I, after the coverage of medical insurance, more people replied that the medical cost of hospital and clinic was reasonable. The people who covered by the regional medical insurance were more dissatisfied with the imposed premium than those who covered by other types of medical insurance in both of cohort I and cohort II. More people in cohort II than cohort I were dissatisfied with the services from hospitals and clinics after implementation of the regional medical insurance. In conclusion. after the coverage of medical insurance, the gap between the poor and the nonpoor still exists in terms of medical care utilization.
