  • The genus Paenibacillus contains a variety of biologically active compounds that have potential applications in a range of fields, including medicine, agriculture, and livestock, playing an important role in the health and economy of society. Our study focused on the bacterium SS4T (KCTC 43402T = GDMCC 1.3498T), which was characterized using a polyphasic taxonomic approach. This strain was analyzed using antiSMASH, BAGEL4, and PRISM to predict the secondary metabolites. Lassopeptide clusters were found using all three analysis methods, with the possibility of secretion. Additionally, PRISM found three biosynthetic gene clusters (BGC) and predicted the structure of the product. Genome analysis indicated that glucoamylase is present in SS4T. 16S rRNA sequence analysis showed that strain SS4T most closely resembled Paenibacillus marchantiophytorum DSM 29850T (98.22%), Paenibacillus nebraskensis JJ-59T (98.19%), and Paenibacillus aceris KCTC 13870T (98.08%). Analysis of the 16S rRNA gene sequences and Type Strain Genome Server (TYGS) analysis revealed that SS4T belongs to the genus Paenibacillus based on the results of the phylogenetic analysis. As a result of the matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF/MS) results, SS4T was determined to belong to the genus Paenibacillus. Comparing P. marchantiophytorum DSM 29850T with average nucleotide identity (ANI 78.97%) and digital DNA-DNA hybridization (dDDH 23%) revealed values that were all less than the threshold for bacterial species differentiation. The results of this study suggest that strain SS4T can be classified as a Paenibacillus andongensis species and is a novel member of the genus Paenibacillus.

  • Animal cell cultures generally require a nutrient-rich medium supplemented with animal serum. Adult bovine serum contains a variety of nutrients including inorganic minerals, vitamins, salts, proteins and lipids as well as growth factors that promote animal cell growth. To evaluate the potential use of gender-specific bovine serum (GSBS) for cell culture, the biochemical properties of male serum (MS), female serum (FS) and castrated-male serum (CMS) were investigated. Overall, the chemical profile of GSBS was similar to that of bovine references except for glucose, creatine kinase, lactate dehydrogenase and potassium. FS showed elevated total protein and sodium concentrations compared to MS and CMS. Proteins present in MS, FS and CMS but absent in fetal bovine serum (FBS) were selected by two-dimensional gel electrophoresis and identified by peptide mass fingerprinting. Some of the identified proteins are known to be involved in immune responses and the others have unknown physiological roles. Moreover, it was found that some proteins such as alpha-2-macroglobulin appeared to be gender-specific with higher contents in FS. Insulin and testosterone was significantly higher in MS, and $17{\beta}$-estradiol and estrone were higher in FS, as compared to the other sera. Taken together, the results indicate that each GSBS has a different ratio of components. Differences in serum constituents may affect cell cultures in a different manner and could be beneficial, depending on the specific aim of cell cultures.

  • 농촌진흥청 원예특작과학원에서는 2003년에 황색 폼폰 화형인 'Restone'에 자주색 폼폰 화형인 'Lollipop'을 교배하여 획득한 실생 집단으로부터 황색 적심 폼폰 화형의 겹꽃 '03B1-82' 계통을 선발하였다. '03B1-82' 계통은 2005년 겨울부터 2007년 3년에 걸쳐 1, 2차 특성검정을 통해 안정성, 균일성 및 흰녹병저항성 검정 및 절화수명에 대해 조사되었고, 2008년에는 우수선발계통으로 '원교B1-142호' 계통번호를 부여받아 3차 특성검정을 실시하여 안정성, 균일성에 대한 연차별 재현성 그리고 주년생산성(촉성, 억제재배), 생산자 및 소비자 기호성을 평가 받았다. '원교B1-142호'는 2008년에 직무육성품종심의회를 거쳐 '옐로우캔디'로 명명되어졌다. 국화 '옐로우캔디'는 10월 하순에서 11월 상순에 자연 개화하는 절화용 스프레이 추국이다. 황색의 적색화심을 지닌 폼폰화형의 겹꽃으로 초세 및 줄기가 강건하다. 특히 여름철 고온기에도 통상화가 많이 발생하지 않으며, 촉성 및 억제재배 등 주년생산이 가능하다. 꽃의 직경이 4.3 cm 내외, 꽃잎수는 소화당 180매 이상, 착화수는 본당 8화 내외의 중형화로 절화수명은 18일 정도이다. 재배상 유의점으로는 둥근모양의 폼폰형이기 때문에 수확시 꽃이 서로 엉키면 꽃이 떨어지는 경우가 있으며, 여름 장마철 또는 겨울철 환기 부족시 흰녹병 발생을 주의하고 주기적인 방제가 필요하다.

  • Medicinal fungi, taken whole or as various forms of extracts, have been used to alleviate, cure or prevent human ailments since pre-historic times. In particular, Asian cultures have incorporated a variety of mushrooms into their medical practices. Chemically pure, bioactive metabolites from fungi have been a mainstay of modern pharmacological research and in addition to antibiotics, include anticancer agents, immunosuppressants, enzyme inhibitors, antagonist and agonists of hormones, and a variety of psychotropic substances. However, to date not many studies have focused on the possible health benefits of odorant volatile organic compounds (i.e., gas phase compounds). An analysis of these compounds for their health related effects will expand the range of compounds available for the treatment of chronic and acute diseases. This review highlights phenolic acids and monoterpenes from Asian medicinal mushrooms (AMMs), which not only produce pleasant odors but also have antioxidant and antibacterial effects. Odorant bioactive volatile phase compounds from medicinal mushrooms remain an essentially untapped source for future medicines, and AMMs remain a promising resource for future pharmacological research.

  • Today's advanced transport and mass media enables people to access easily and frequently to traditional costumes from different countries in the world. Consequently, fashion designers who are fascinated by the variety and beauty of traditional costumes, tend to adapt them to modern fashion design. The continuous study of traditional costumes at such time contains a meaning as a source of inspiration for the creation of a new fashion design. Therefore, among various costumes of the world, this study will focus on the costume of Palestine, that is situated at the crossroads of Europe, Asia and Afria and has exchanged various historical cultures with other cultural regions. It, especially, expects to provide a unique idea in the material modification field of today's fashion design by examining mainly the embroidery ornament which is the most distinctive feature of Palestinian costume. The conclusion was revealed that Palestinian women's costume largely consists of embroidered silk and cotton garments with a V-slitted square panel (gabeh) attached to the chest part. And a variety of luxurious embroidery was employed to emphasize different parts of the dress. These embroideries differ from area to area. Especially the embroidery from Bethlehem was well-known in many places and influenced those of other regions.

  • To develop a functional chungkookjang; the anticancer effects of chungkookjangs prepared with different varieties of soybeans, starters, fermentation periods and seasoning additive ratios; were studied against AGS human gastric adenocarcinoma cells using the MTT assay, at different stages chungkookjang processing. The chungkookjang samples exerted different antiproliferative effects according to the variety of soybeans used. The chungkookjangs manufactured with soybean var. manrikong exhibited the highest cytotoxicity against AGS human cancer cells. The chungkookjangs fermented with rice straw and B. licheniformis strongly inhibited the growth of the AGS human cancer cells. All fermented chungkookjangs had a strong inhibitory effect on the growth of the cancer cells; however, the non-fermented soybean (chungkookjang) showed a low inhibition rate. The fermented chungkookjangs mixed with red pepper powder (RPP) and garlic exhibited strong antiproliferative effect against the cancer cells, and chungkookjang prepaved with 1.1 % RPP and 1.1 % garlic showed the highest cytotoxicity against the cancer cells. The functional chungkookjang fermented with soybean variety of manrikong and B. licheniformis for 3 days at 4$0^{\circ}C$ and then mixed with 7.9% salt, 1.l% RPP and 1.1% garlic, exhibited a higher antiproliferative effect than the chungkookjangs prepared by traditional or modified methods, according to the MTT assay. The functional chungkookjang exhibited a similar anticancer effect to the traditional doenjang. These results indicate that the fermentation period and the ratio of seasoning additives, as well as the variety of soybeans and starter cultures may affect the degree of the anticancer effect of chungkookjang.

  • Ecological Engineering (EE) refers to all sustainable engineering that can reduce damage to ecosystems and that adopts ecology as a base and safety as an orientation in order to implement conservation of biodiversity and sustainable development. In short, EE attempts to safeguard the ecological environment while any essential construction projects proceed. EE encompasses many fields, including construction skills, ecosystem preservation, landscape, and even related cultures and so on. Such variety results in greater complexity of construction, and, consequently, indirectly increases the difficulty of construction quality control. The objective of our research is to explore a promising model for EE via an extensive literature survey. This model includes three principal stages: plan-design, construction, and maintenance, along with individual accompanying phases concerned with quality control and vital management. In this article, a river restoration example is adopted to describe in detail the critical points of quality control in the three stages (plan-design, construction, and maintenance) of the construction life cycle. This study proposes an integrated structure for quality management of EE to guarantee its quality and to enhance its core applications in order to achieve long-lasting preservation of the environment.
