Geyonggi-geommu have developed based on the long history of Korean sword dance. Han Sung-joon, the great master of modern music and dance of Korea during the Japanese colonial period, collected and reconstructed folk dances that had disappeared or were cut off due to the policy to obliterate Korean culture through Chosun Music Dance Research Society. Since then, it has been passed down to Kang Sun-young and Kim Geun-hee that has designated as the Intangible Cultural Property No. 53. of Geyonggi-do in 2011. This study focuses on highlighting the uniqueness of Geyonggi-geommu for proper modeling and transmission of Geyonggi-geommu with historical significance so as to understand and preserve the Intangible Cultural Heritage. This study examines the transmission system of Geyonggi-geommu, followed by Kang Sun-young and Kim Geun-hee, originated by the master Han Sung-Joon of Geyonggi-geommu. Geyonggi-geommu has its uniqueness of using the pure Korean dance terminology established by the holder Kim Geun-hee at the time of designation of intangible cultural properties in Gyeonggi-do. The unique features of Geyonggi-geommu are performed and transmitted in two forms, Daemu(Group dance) and Holchum(Solo dance) which are not currently found in other regions. This is meaningful to passed down according to the original form of Geommu(Sword dance). In particular, the Holchum(Solo dance) is a form of artistic dance, showing the beauty of the sword dance during the Chosun Dynasty. In short, Gyeonggi-geommu can be described as an artistic dance with a soft and strong temperament considering its unique features.

In recent years, the occurrence of bacterial diseases of soybean has been increasing due to the continuous rise in spring temperature and the humid weather as a result of rain concentrated at the middle and late stages of crop growth. The resulting severe economic damage is also a concern. Unfortunately, there are no precise data on the occurrence and damage to lay the foundation for bacterial disease control in soybean in the Chungbuk Province. Therefore, the present study investigated the occurrence of major bacterial diseases, namely bacterial pustules, bacterial blight, and wildfire, in different soybean varieties in 410 fields in the Chungbuk Province in 2017. The incidence rate of bacterial pustules in the affected fields was 76.6%, and the incidence rate of infected plants was 29.3%. The incidence rate of bacterial blight in the affected fields was 13.9%, and the incidence rate of infected plants was 4.6%. The incidence rate of wildfire in the affected fields was 23.2%, and the incidence rate of infected plants was 10.1%. The overall incidence rate of bacterial diseases in the soybean fields where the diseases originated was 37.9% for bacterial pustules, 21.0% for bacterial blight, and 25.0% for wildfire, indicating that the disease incidence rate in fields where the disease originated was generally high. Among different varieties, the incidence rate of bacterial pustules was the highest in sprout soybean (88.9%), followed by Seoritae (84.0%) and Daewon (81.2%). The incidence rate of bacterial blight was the highest in the Daewon (19.6%), followed by Seoritae (15.2%) and sprout soybean (12.5%). The incidence rate of wildfire was the highest in sprout soybean (25.0%), followed by Daewon (24.7%) and Seoritae (5.4%). Meanwhile, in Uram, the incidence rate of bacterial pustules (7.1%) was the lowest, and this variety was not affected by bacterial blight or wildfire.

Wheat streak mosaic virus (WSMV), a member of the genus Tritimovirus in Potyviridae, severely impacts wheat and corn seed worldwide, but has yet to be detected in Korea, and hence, every effort should be made to prevent its introduction. To prevent WSMV from entering the country, it is necessary to prepare a specific, sensitive, simple, and fast detection method for routine application to plant quarantine procedures. For this reason, a two-step diagnosis system consisting of RT-PCR and nested PCR is being used for WSMV detection. In addition, a novel positive control was developed for use with the system. WSMV has been detected in seed sweet corn from Japan and seed wheat from USA by a two-step diagnosis system, the details of which are described in this study. After sequence analysis, similarities of 80.6 and 100.0% with other isolates were determined by BLAST. They showed the same topology, which was classified as 4 genotypes by various phylogenetic trees, using a poly protein encoding sequence amplification. In this analysis, WSMV-JSweet-corn2868 (JX845574) is classified as clade B, while WSMV-Uwheat1944-1 (KC754959) and WSMV-Uwheat1944-2 (KC754960) belong to clade D.

The Assembly plenary session on December 3, 2017 passed a Product Liability Amendment bill that introduced clauses concerning consumer burden of proof and punitive damage reimbursement. More specifically, these newly approved provisions will reduce the burden of proof placed on consumers and levy triple punitive damage on suppliers. Significant increases in the number of product-liability lawsuit and the number of related insurance contracts are expected. Since military aircraft are designed for operational purpose(seeking greater combat effectiveness over greater safety) and used in high-risk environment, it is practically impossible to obtain an affordable product-liability insurance, Without having any backup plan, military aircraft manufacturers directly face all sort of liability risks under Product Liability Act, Warrant Liability Act and Non-Performance of Contract Act. The U.S. experienced similar problems when they first implemented their product-liability law in 1970s. There had been a big dispute among legal practitioner, insurance professionals and scholars concerning military aircraft manufacturer's liability. In order to settle the issue, the U.S. Supreme Court has established a new precedent of Government Contractor Defense(GCD). The U.S. government also included an indemnity clause for military aircraft manufacturers in their FMS Contract with the Korean government. Likewise, Korean military aircraft manufacturers should 1) clearly understand their current position that they cannot afford expensive product-liability insurance and the cost is not accounted in the military procurement calculation, 2) estimate potential liability risks with the ongoing overseas export expansion in mind, 3) set up appropriate risk management measures through regulatory reform and policy development.

Bioaerosols are comprised of particles 0.02-100 μm in size that originate in natural and artificial environments, and as a result of human activities. They consist of microorganisms including viruses, bacteria, fungi, and protozoa; fungal spores; microbial toxins; pollen; plant or animal material; expectorated liquid from humans; and glucans (peptidoglycan and β-glucan). Bioaerosols can cause respiratory and other diseases in humans and animals. In this study, bioaerosol samples acquired from agricultural sources, livestock, a sewage treatment plant, a beach, and a pristine area were analyzed to identify and phylogenetically characterize culturable microorganisms. The isolated bacteria exhibited regional differences, with different species dominating. However, Bacillus cereus was isolated in all samples, with a total of 31 strains isolated from all areas, and Acinetobacter baumannii was isolated from an indoor poultry farm. In addition, bacteria determined to be of novel genus or species of the genera Domibacillus, Chryceobacterium, Nocardioides and family Comamonadaceae were isolated from the agricultural, livestock and beach environments.

Groundwater heat pump (GWHP) systems must consider phenomena such as clogging to improve system efficiency and maintenance. In this study, we evaluated the prokaryotic diversity in a boring slime sample obtained at a depth of 10 m, which represented an undisturbed sample not affected by aquifer drawdown. Bacteria belonging to the phyla Proteobacteria (20.8%), Acidobacteria (18.8%), Chloroflexi (16.9%), and Firmicutes (10.2%) were found. Additionally, 144 species were identified as belonging to the genus Koribacter. Archaeal phyla were detected including Thaumarchaeota (42.8%), Crenarchaeota (36.9%), and Euryarchaeota (17.4%) and the class level comprised the miscellaneous Crenarchaeota group (MCG), Finnish forest soil type B (FFSB), and Thermoplasmata, which collectively accounted for approximately 69.4% of the detected Archaea. Operational taxonomic units (OTUs) were analyzed to reveal 3,565 bacterial and 836 archaeal OTUs, with abundances of 7.81 and 6.68, and richnesses of 5.96E-4 and 2.86E-3, respectively. The distribution of the groundwater microbial community in the study area showed a higher proportion of non-classified or unidentified groups compared to typical communities in surface water and air. In addition, 135 (approx. 1.9%) reads were assigned to a bacterial candidate associated with clogging.

This study examines potential growth and different perspectives on green-walls, which are being re-evaluated recently. The aim is to identify the viewer preferences concerning the walls by collecting a wide spectrum of information to create an interior design related comprehensive and intellectual database. Also based on this proposition, choosing a green surface of indoor wall as a specific example stimulus, identifying a relationship betweeationsviewer's preference factors. The relationship will formulate detailed and absolute qualities, which will reach potential areas that the green walls can be widely applied in. As a result of a factor analysis, the viewers classified into the 3 factors as is pleasant, gorgeous and rich about the stimulus. Preferred key factors, which are closely related to emotional image language, were; cool, tidy, comfortable and beautiful. The common factors in preferred design stimulus, in order of importance are color>elements>image/form/plants. Specific levels of design factors according to relevance are contrast>furniture> modern>central/creeper foliage plants. In the meantime, this study is leading the process of quantitative measurement of green-walls to a new design direction and it is critical to consistently experimenting to back up the theory with solid evidence.

Poly(${\varepsilon}$-caprolactone) (PCL) nanofibers and PCL/silica membranes were synthesized by sol-gel derived electrospinning and casting, respectively. Smooth PCL nanofibers were obtained from the precursor containing N,N-dimethylformamide (DMF). PCL/silica membranes were prepared by varying the tetraethyl orthosilicate (TEOS) contents from 0 to 40 vol% to investigate the effect of silica addition on mechanical properties and cytotoxicity of the membranes. Although the strength of the membranes decreased from 12 to 8 MPa with increasing the silica content, the strength remained almost constant 7 weeks after dipping in phosphate buffered saline solution (PBS). The strength reduction was attributed to the presence of a patterned surface pores and micro-pores present in the walls between pores. The crystal structure of the membranes was orthorhombic and the crystallite size decreased from 57 to 18 nm with increasing the silica content. From the agar overlay test, the PCL/silica membranes exhibited neither deformation and discoloration nor lysis of L-929 fibroblast cells.

Objective : This study was to investigate the relationship between sensory processing patterns and sleep quality for poor sleepers enrolled in universities. Methods : The participants are 191 students, aged 18 to 25, at the 6 universities located in Busan, Daegu, and other Gyeongsang Provinces. These participants completed the Korean version of Adolescent/Adults Sensory Profile (AASP) and the Pittsburgh Sleep Quality Index (PSQI). Results : The group with lower sleep quality of this study participants suggested low but positive correlation with sleep disturbance which is one of sleep quality components of the PSQI. Low sensory registration suggested high positive correlation and Sensory sensitivity suggested low positive correlation with daytime dysfunction. Conclusion : We identified that sensory processing patterns and sleep quality may influence each other and sleep quality can be more significantly influenced by specific sensory processing pattern. More studies requires on sleep quality and sensory processing patterns in children, adults, and elders.
