Objectives: Bioaerosols released by treating organic-waste resources cause a variety of environmental and hygiene problems. The objective of this study was to investigate the distribution characteristics of the airborne bacteria emitted from a pig manure composting plant, a principal site for organic-waste resource facilities. Methods: Three types of pig manure composting plant were selected based on fermentation mode: screw type, rotary type and natural-dry type. Each site was visited and investigated on a monthly basis between September 2009 and August 2010. A total of 36 air samplings were obtained from the pig manure composting plants. The air sampling equipment was a six-stage cascade impactor. Quantification and qualification of airborne bacteria in the air samples was performed by agar culture method and identification technique, respectively. Results: The mean concentrations of airborne bacteria in pig manure composting plant were 7,032 (${\pm}1,496$) CFU $m^{-3}$ for screw type, 3,309 (${\pm}1,320$) CFU $m^{-3}$ for rotary type, and 5,580 (${\pm}1,106$) CFU $m^{-3}$ for natural dry type. The screw type pig manure composting plant showed the highest concentration of airborne bacteria, followed by the natural dry type and the rotary type. The ratio of respirable to total airborne bacteria was approximately 40-60%. The predominant genera of airborne bacteria identified were Micrococcus spp., Staphylococcus spp. and Escherichia spp. Conclusion: Monthly levels of airborne bacteria were highest in August and lowest in November regardless of fermentation mode. There was no significant correlation relationship between airborne bacteria and environmental factors such as temperature, relative humidity and particulate matters in pig manure composting plants.

This study examined the contents of 'Adolescent's Consumption Life' unit in 12 Technology Home Economics textbooks used in the 2009 revised curriculum to analyze the contents of school consumer education. The main summary of this study is as follows: First, the contents of consumer education in the unit of 'Adolescent's Consumption Life' consisted of five criteria including the understanding of adolescent consumer, consumer's right and responsibility, reasonable purchase, resolution to consumer problems, and the formation of new consumption culture. Second, significant differences were found in the contents of consumer education among textbooks because basic concepts have been not been clearly defined yet. Third, essential content was either omitted or hard to understand. Thus, some contents elaborations were inappropriate for students' level. Fourth, there were some limitations in drawing interest and attention from learners and developing dispute resolution competence, since the textbooks mainly comprised the theory-oriented contents of consumer education. Fifth, cautious consideration needs to be taken with regards to clear understanding of basic concepts and systematic and consistent contents composition for coherent and organized school consumer education. These research findings are anticipated to provide basic information of Technology Home Economics textbooks to teachers, and will be utilized as basic data in organizing textbook contents or developing efficient teaching-learning programs for consumer education.

Cordyceps cardinalis was reported in Japan and the USA in 2004, and its fruiting bodies have recently been cultured in Korea. Herbarium specimens preserved at the Cordyceps Research Institute, Mushtech, Korea were revised and identified as C. cardinalis, based on morphological characters and conidial structures. Most of the C. cardinalis specimens were collected from Mt. Halla in Jeju-do. The effects of various nutritional sources and environmental conditions such as temperature and pH on mycelial growth of C. cardinalis were studied. Oatmeal agar, Martin's peptone dextrose agar, and Schizophyllum (mushroom) genetics complete medium plus yeast extract resulted in the best mycelial growth. Among carbon sources, cereals, and nitrogen sources, maltose, oatmeal, and peptone resulted in the best mycelial growth respectively. Mineral salts helped to increase growth rate but only resulted in thin mycelial density, similar to water agar. A temperature of $25^{\circ}C$ and a pH of 7 resulted in the highest mycelial growth. Based on these results, a Cordyceps cardinalis composite medium (CCM) was formulated with 1% maltose, 2% oatmeal, 1% peptone, and 2% agar. Use of the CCM resulted in slightly better mycelial growth than that of other commonly used agar media. Only organic nitrogen sources imparted a reddish pigmentation to the agar media, but this character diminished after several subcultures. A 7 day culture duration resulted in the best mycelial growth.

The most common abnormality of the umbilicus in the foal is the patent urachus. Patent urachus may be a congenital or acquired condition in foals in which the urachus fails to close spontaneously at or shortly after parturition. A 17-day-old male Thoroughbred foal was requested to the Veterinary Pathology Laboratory of Cheju National University. The foal showed clinical signs such as umbilical urination, anorexia, depression, lethargy, and abdominal pain for 10 days. Because of the umbilical urination, the surgery for patent urachus was performed, but he died next day. Grossly, many pale yellowish foci 10-20 mm in diameter were scattered on the throughout surface of lungs. Severe subcapsular hemorrhage was observed in left kidney. Large milky yellow mass 10X6-7 cm in size was found in the adjacent area of right kidney. Histopathologically, many abscesses with bacterial cocci were scattered in the blood vessels or adjacent pulmonary parenchyma of lungs. Severe numerous abscesses with intralesional bacterial cocci were mostly occupied in the abdominal mass from right kidney. Gram staining for tissue sections demonstrated numerous Gram positive cocci in pulmonary and abdominal abscesses. In bacterial culture, catalase-positive beta-hemolytic colonies were isolated and confirmed as Staphylococcus (S.) aureus by Vitek system. Based on the results, acquired patent urachus and then multiple abscesses may be originated from the umbilical cord infected with S. aureus in this foal.

This study finds surface color and functions of natural dyeing from Chamaecyparis obtusa leaves which help cure skin problems such as atopic dermatitis. This study also seeks to find dyeing properties and functions of natural colorants derived from Chamaecyparis obtusa and Rubia tinctorum on silk. Dyeing properties and functions are compared between silks dyed with Chamaecyparis obtusa and silks composite-dyed with Chamaecyparis obtusa and Rubia tinctorum. The comparison examines the feasibility of developing healthy and high functional fabrics and wellness of fashion merchandises. Silk dyeing with Chamaecyparis obtuse leaves yields yellow and double coloring from Chamaecyparis obtusa; however, Rubia tinctorum yields yellow/red on silks. Silks dyed with Chamaecyparis obtusa and silks composite-dyed with Chamaecyparis obtusa and Rubia tinctorum show a high level on dry cleaning, ultraviolet protection and deodorization. Especially, the dyed silks from leaves of Chamaecyparis obtusa show a 99.7% antimicrobial effect against staphylococcus aureus ATCC 653B. Silks composite-dyed with Chamaecyparis obtusa and Rubia tinctorum are better known for medicinal herb for dermatitis, and natural colorant, Rubia tinctorum does not improve significantly functions compared with silks dyed with Chamaecyparis obtusa. However, the dyeing properties improve by composite dyeing. This implies that ways to maximize effects of tie-dyeing technique could be developed.

This study looks into the dyeing properties and functionality of cotton fabrics dyed in both the Spirodela polyrhiza extract and the extract resulting from the mixture of Salvia plebeia R. Br. and Spirodela polyrhiza. Since the UV-Vis Spectrum of the methanol extract of Spirodela polyrhiza shows absorption peaks at 256, 268nm, and 345nm, it can be inferred that the compound that Spirodela polyrhiza contains is a flavonoid. In addition, it can also be presumed that, by analyzing the infrared absorption spectrum of Spirodela polyrhiza, the plant contains flavonoid compounds, just like Salvia plebeia R. Br.. The UV protection factors of the cotton fabrics dyed in both the Spirodela polyrhiza extract and the extract from the mixture of Salvia plebeia R. Br. and Spirodela polyrhiza were 50+, presenting outstanding UV protection factors. The deodorization rate of the cotton dyed in the Spirodela polyrhiza extract was between 30 and 120 minutes, and the rate rose from 92% to 97% as time passed. The deodorization rate of the cotton dyed in the extract from the mixture of Salvia plebeia R. Br. and Spirodela polyrhiza increased from 88% to more than 91%. The result also revealed that overall the fastness of color, including color fastness to washing related to change in color, as well as the color fastness to light of the fabric dyed in the extract from the mixture of the two plants improved, compared to the cloth dyed only in Spirodela polyrhiza extract. Furthermore, the antibacterial activity was also strengthened.
