벼메뚜기는 분류학적으로 메뚜기목(Orthoptera), 메뚜기과(Acrididae)에 속하는 곤충으로 작물에 피해를 주는 해충으로 인식하고 있지만 예로부터 단백질 보충을 위하여 채집하여 튀기거나 볶음요리 로 이용해 왔다. 벼메뚜기는 갈색거저리, 쌍별귀뚜라미 등과 함께 식품공전에 등록되어 있으나 1년 1세대로 가을철에 채집하여 이용하는 실정으로 공급확대에 한계가 있다. 최근 우리나라에서 벼메뚜기를 사육하고자 하는 농가와 다양한 용도로 가공을 통해 이용하려는 수요가 점차 증가하고 있으나 연중사육기술이 개발되지 않아 대량사육하는 농가가 거의 없는 실정이다. 이에 벼메뚜기의 연중대량사육기술 뿐만 아니라 인공사료 및 자동화 사육시설 개발에 따른 생산비 절감 기술 개발이 필요한 실정이다. 벼메뚜기의 먹이로는 여름작물로 옥수수, 수단그래스, 겨울작물로 밀, 보리 등의 볏과작물이 있으며 많은 양의 생엽과 발육에 적합한 작물의 선발 및 볏과작물의 통곡실 가루를 이용한 인공사료의 개발로 먹이공급 부족 시 15~20일 급여 가능하며, 벼메뚜기 사육시설로 단독형, 연결형, 절충형 등의 사육시설을 개발하여 연결형 사육시설의 수확량과 생존율이 가장 높았으며, 예취 급이 노동력이 단독형의 16% 소요되었다.

Ultraviolet B (UVB) exposure is a risk factor for skin damage resulting in oxidative stress, inflammation, and cell death. The purpose of this study was to investigate the physicochemical properties of Platycodon grandiflorum (PG) to improve its biological activities using a three-step steaming process. We investigated the protective effects of PG and steamed PG extracts on human dermal fibroblasts (HDFs) against UVB radiation-induced oxidative stress and inflammation as well as the underlying mechanisms. The antioxidant potential of the PG extracts was evaluated by measuring the 2,2-diphenyl-1- picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) scavenging activity. ABTS and DPPH were shown by the 0, 30, and 70% ethanol extracts of 2S-PG and 3S-PG (IC50, 28~45 and 27~30 μg/mL, respectively). Treatment of UVB-irradiated cells with steamed PG (25~400 μg/mL) did not affect their viability. The streamed PG extract suppressed UVB-induced generation of reactive oxygen species (ROS). In addition, streamed PG extract reduced cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) protein expression in UVB-irradiated HDF, regulating nuclear factor (NF)-κB expression. These findings suggest that steamed PG extract may be potentially effective against inflammation associated with UVB-induced oxidation stress.

The antioxidant and antitumor properties of natural products, often recognized in traditional medicine systems, represent therapeutic modalities to reduce or prevent uncontrolled oxidation processes which in turn potentially ameliorate or tumor based symptoms of chronic diseases. We have studied the antioxidant and antitumor effects of Amanita muscaria (A. muscaria) in vitro and examined whether the A. muscaria has synergistic effects on antioxidant and antitumor properties. Although A. muscaria induced a dose-dependent increase in antioxidant activity, the latter has a consistently higher antioxidant effect. In mouse monocytes, the lipopolysaccharide- (LPS-) induced tumor necrosis- (TNF-) synthesis was significantly inhibited by A. muscaria in a dose dependent manner and synergistic effects were clearly demonstrated with the A. muscaria on TNF- inhibition. A. muscaria effect was also evident on inhibition of nuclear factor-kappa B activity, cyclooxygenase-II activity, and lipid peroxidation in mouse monocytes. This presented results may be a starting point for a comprehensive characterization of biological effects of A. muscaria.

To determine the medicinal properties of Pleurotus cornucopiae and Safflower Oil (PS), the osteoblast effect was investigated. PS can prevent estrogen deficiency-induced bone loss. It was taken the measurements of biochemical factors such as serum osteocalcin, alkaline phosphatase, IGF-1, and bone status. Forty adult female Sprague-Dawley rats were randomly assigned to four equal groups for 12 weeks of treatment: (1) sham operation (SHAM) + vehicle; (2) ovariectomy (OVX) + vehicle; (3) OVX + 17β-estradiol (25 μg/kg); (4) OVX + PS (300 mg/kg/d, PO). At the end of the experiment, bone turnover, and trabecular microarchitecture were assessed by micro-computed tomography (micro-CT), and histopathology, respectively. Ovariectomized rats experienced remarkable increases in global volumetric bone density, and trabecular microarchitecture deterioration. These OVX-induced pathological changes are reversible in that most of them could be mostly corrected upon 17β-estradiol treatment. PNS treatment significantly prevented bone mass loss and microarchitecture deterioration. Moreover, PS enhanced osteoblast activity but suppressed osteoclast turnover, as evidenced by decreased levels of serum C-terminal telopeptides of type I collagen and elevated levels of alkaline phosphatase. PS mitigates estrogen deficiency-induced deterioration of trabecular microarchitecture.

It has been reported that collagen and elastin inhibit skin wrinkle formation. Skin elasticity is closely associated with the formation of wrinkles induced by UV exposure. In this study, we investigated the protective effects Pleurotus ostreatus (P. ostreatus) on UVB irradiation induced wrinkle in hairless mice. We evaluated for their free radical-scavenging activities against 1,1-diphenyl-2-picrylhydrazyl (DPPH), the anti-elastase activities, and for their anti-matrix metalloproteinase-1 (MMP-1) activity in human skin fibroblast cells. In the wrinkle measurement and image analysis of skin replicas, the results showed that P. ostreatus significantly inhibited wrinkle formation caused by chronic UVB irradiation. These results suggest that P. ostreatus has anti-wrinkle activity.

The nematode Bursaphelenchus xylophilus is the causal pathogen of pine wilt disease in Korea. Currently, it is reported that B. mucronatus also has a low pathogenicity. Despite this difference in pathogenicity, it is very difficult to differentiate these two species due to similarity in morphological characters. The sequence variation of internal transcribed spacer (ITS) and intergenic spacer (IGS) regions of ribosomal DNA has been used for species identification and phylogeny of B. xylophilus and B. mucronatus. But, the IGS region sequence data of B. mucronatus has been only reported in Portugal. In this study, We analyzed genetic variation on ITS and IGS regions of B. xylophilus and B. mucronatus (Asian genotype, European genotype) based on rDNA gene sequences, and conducted phylogeography using TCS network. When the each isolates was determined the phylogenetic analysis using the neighbor-joining method, Bursaphelenchus species were divided into each groups, and showed low variation within each species. In the TCS analysis, The isolate of B. xylophilus and B. mucronatus (Asian genotype and European genotype) were divided into each groups and confirmed slightly genetic distance within species. B. mucronatus European genotype has possibility of new species different with Asian genotype.

S. aureus is reported as a major cause of nosocomial infections after dental care and involved in endocarditis, bacteremia, osteomyelitis, peritonitis, and soft tissues etc. It is very important to identify the distribution and the diversity of toxin gene associated with the S. aureus expression in dental care patients with periodontitis directly for an effective prevention and treatment of dental diseases. Fifty four strains of S. aureus were isolated from the saliva of 129 patients who were diagnosed with periodontitis at dental clinics and hospitals located in Seoul. The distribution of the virulence gene and the genetic diversity of the strains were studied using the polymerase chain reaction with isolated strains. The enterotoxin test showed Seb was the most frequent gene with 88.9%. The hemolysin gene of Hla, Hib and Hld were the most frequently gene with 98.1% (53 strains), leukocidins gene of lukM showed 90.7% (49 strains), and laminin binding protein gene of Eno showed 100% (54 strains), respectively. The diversity of the enterotoxin gen was held as Seb-Seg-Sei gene of 35.2% (19 strains), the diversity of hemolysin gene of Hla-Hlb-Hld gene was 98.1% (53 strains) and the diversity of leukocidins gene of LukD-LukM were 88.9% (48 strains), respectively. Patients with dental disease showed somehow high toxin gene expression so that S. aureus in dental care area is judged to show very highly pathogen with a high and infection rate. In the future, additional studies for these toxin genes seem to be required.

The purpose of this study is to investigate learning desire based on the interests, application of clothing and textiles in Technology․Home Economics curriculum of middle school. For this research, a questionnaire survey was conducted to 404 middle school students living in Seoul and Kyunggi areas. The data was analyzed by frequency, descriptive statistics, Cronbach's α coefficient, one-way ANOVA, and Duncan-test using SPSS 14.0. The conclusions of this study are as follows: First, the perception of middle school student for Technology․Home Economics was low. Students were interested not in the clothing and textile education but in getting dressed specially, and purchasing of clothes. Second, the more interested in the area of clothing and textiles, the higher is the application of apparels coordination, apparel purchase, and apparel management. And the more interested in the area of clothing and textiles, the higher is the desire in class contents. Therefore, teaching-learning methods should be developed to improve middle school students' interests, and applications in the clothing and textiles.

This study examines the appearance management attitude factor of male college students and groups them according to their characteristics. Then this research analyzes their interest in knitwear, buying behavior, and characteristics to see what kind of differences exist. The results of the research are as follows: First, after conducting a factor analysis to identify the appearance management attitude of male college students, 3 factors emerged(sought personality, pursued trends, and appearance interest). Second, as a result grouping the students according to their attitude. It is created 3 groups(fashionista group, personality group, and appearance interest group). Third, for the interest in knitwear, the fashionista group had the highest interest in knitwear, with a preferred brand when purchasing. Fourth, the fashionista group that values personality and latest trends was more likely to purchase knitwear than the personality group or the appearance interest group. Finally, the majority preferred solid colors. Over 50% of the students preferred knits without any patterns. Also, the most preferred 100% cotton. As this survey was only surveyed in Seoul and Gyounggi areas. The next research requires to be surveyed in a more comprehensive area. Additionally, male college students must more effectively be segmented and surveyed to get accurate results.

The purpose of this study is to understand factors of risk perception and purchase obstruction by consumer characteristics and purchase experience of clothing in online. The collection of the research materials was progressed by online and offline. Out of 374 usable questionnaires used for examining this study, 278 questionnaires were collected from offline and 107 questionnaires were collected from online. Frequency analysis, factor analysis, reliability analysis, t-test, One-way ANOVA and multiple regression analysis using SPSS WIN 12.0 were conducted. Three factors of perceived risk were extracted: harmonic/image, quality/shopping process, payments. Based on these dimensions, ANOVA was conducted. The results indicated that the more purchasing experience people had, the less the extent of perceived risk they got, and quality/shopping process risk mostly among them. As the factors which obstruct purchasing decision, a security obstruction, a reliability obstruction, a convenient obstruction and an information insufficient obstruction are extracted. Also, the factors have got the result of same aspects as the perceived risk recognized by the Internet shopping experience. Meaningful differences between groups appear at security obstruction, reliability obstruction, and convenient obstruction. Perceived risk almost influenced on purchase obstruction when purchasing clothes in Internet shopping mall. When consumers perceiving harmony/image risk highly make decisions, they usually hesitate or abandon due to reliability obstruction, convenient obstruction. All the factors: including security obstruction, reliability obstruction, convenient obstruction and information insufficient obstruction made consumers perceiving quality/shopping process risk highly obstruct purchase decision.
