  • We have analyzed the torque signals measured in synthetic antiferromagnetic (SAF) coupled CoFeB/Ru/CoFeB thin film, which signals were drastically changed at flopping field ($H_F$) and saturation field ($H_s$). The minimum value of negative uniaxial anisotropy constant ($-\;K_1$) was appeared at HF. The $-\;K_1$ was due to the zero net magnetization by the antiferromagnetic coupling between two ferromagnetic layers. Whereas, the biaxial anisotropy constant (K2) was induced in the field range of $H_F$ < H < $H_s$. The induced $K_2$ was originated from deviation angles between magnetization directions of two ferromagnetic layers. And at H > $H_s$, intrinsic uniaxial anisotropy constant of CoFeB layer was observed. These change of the anisotropy constant with magnetic field was explained by the magnetization process of two ferromagnetic layers based on Stoner-Wohlfarth model calculation for SAF thin film.

  • Quality characteristics of conventional and whey noodles were investigated by studying the textural properties. cooking properties, and sensory characteristics. The whey noodles were prepared by mixing whey powder with the wheat flour before noodle production, with the mixture ratio ranging between 1 and 7% in volume. The results are summarized as follows : the addition of whey powder noticeably improved the textural characteristics of the cooked noodles, i.e. hardness, gumminess, and chewiness. The best results were obtained using the following percentage of whey in the mixture: the hardness with 1% added, the gumminess and chewiness with 3% added, and the elasticity with a 7% addiction. The tension force also increased with addition of whey powder, The highest tension force was obtained when 3% of the whey was mixed. While the cooking water of the general noodles displayed a light reddish tint, the cooking water of the whey noodles had a yellow-greenish tint. The cooking water of the whey noodles was more turbid than that of the conventional noodles. The whey noodles increased in volume more than the conventional noodles. after cooking. There was no difference in weight increase and water absorption rates between both types of noodles. More favorable results were shown for appearance, color, texture, and sensory acceptability in the whey noodle than in the conventional noodles.

  • This study measures the effect of oral health promotion program based on community networking for elementary school students in community child center. The community networking were constructed of community health center, headquarters for community child center and school of dental hygiene in community. First, we were educated the student and teacher of community child center, separately. Community health center planned and evaluated the program, and school of dental hygiene ran the maintenance program once a month for 3 months and evaluated the program. The teacher of community health center were supported and monitored the children. The comparison was done in independent t-test of awareness, knowledge and behavior of children of community child center in both lower grades and upper grades and paired t-test of patient hygiene performance (PHP) index was conducted before and after oral health promotion program. As a result, PHP index and oral health knowledge increased significantly after oral health program in lower grades and upper grades (p<0.001). The positive attitude for oral health about "Whatever I do, my tooth-will be decayed" increased more in upper grades better than lower grades after oral health promotion program (p<0.05). We suggest that oral health program based on community networking should be constructed for oral health promotion of elementary school students in community child center.

  • This study was conducted to investigate the dietary habits and nutritional knowledge of 5th and 6th graders and the teachers' perception of dietary life education at the elementary schools in Chuncheon area. The children who had breakfast and supper everyday accounted for 54.1% and 80.3% each. Children consumed 'breads or confectioneries'(42.6%) and 'fruits or juices'(39.3) as snacks. Only 57.4% of the children had balanced diet. Only 59% of the children answered correctly at the nutritional knowledge test, and only 75% had good dietary behaviors. About 78% of the teachers had the experiences of dietary life education, and they taught it in class(38.9%) or at school lunchtime(35.2%). The teachers answered that the major nutrition problems of elementary students were bad eating habits(37.7%) and too much ingestion of fast or instant foods(36.2%). They also answered that dietary life education was necessary(79.7%) and should be started more earlier(87.0%). Ironically, about 49% of the teachers answered that dietary life education should be taught by dietitians even if the teacher who spent most of the time with their students is the best person for dietary life education at school. It should be done in children's daily life, especially for elementary school students. Therefore, teachers should recognize the importance and the specialty of dietary life education at the elementary schools.

  • This experiment was carried out to investigate the proper planting method of Rehmannia glutinasa Liboschitz. A Chungbuk local cultivar was sown on the seed bed of 200cm with the planting density of 30cm(6 rows) $\times$ 8.5cm(30 rhizome per $\textrm{m}^2$). The experimental design was randomized block design with 3 replications. And the result was summarized as follows. The emergence date of level Planting(control : 0$^{\circ}$) was May 23, but the emergence dates of Oblique planting(45$^{\circ}$) and Upright planting(90$^{\circ}$) treatments were later than the control by 2~4 days. And the leaf length and the ratio of leaf length/leaf width were not significantly different. As compared with the 29.2cm and 10.0mm of the rhizome length and the rhizome diameter of level planting treatment, the rhizome length of Oblique planting treatment was decreased by 3.4cm and 0 mm. The length and diameter of rhizome of the Upright planting treatment was decreased by 2.8cm and 1.0mm. And the order of sugar content was level Planting > Oblique planting > Upright planting. The total yields were decreased by 9% in the Oblique planting and by 15% in the Upright planting compared to 1,203kg/10a in the control, and the commercial yields showed the same tendency. The level planting treatment was found to be most proper for sowing of Rehmannia glutinasa Liboschitz in the middle inland region of Korea.

  • 블루베리는 진달래 과(Ericaceae) 산앵도나무 속(Vaccinium)의 낙엽성 또는 상록성의 저수고성 또는 반교목성의 과수로, 뉴욕 타임즈가 선정한 세계 10대 장수식품의 하나로 알려져 있다. 우리나라에는 전부터 정금나무, 월귤나무, 모새나무, 산앵도나무 등이 자생하고 있으나, 경제적인 가치가 있는 종은 Vaccinium Cyanococcus로 북미지역에서 육성된 품종들이 들어와 재배되고 있다. 처음 도입된 해는 1965년경으로 지금도 40년 이상 된 나무들이 있고, 상업적으로 재배되기 시작한 것은 2000년이고 공식적인 연구는 2004년 국립원예특작과학원에서 시작되었다. 한국블루베리협회 소식지에 주기적으로 기록되기 시작한 재배면적은, 2007년 112ha, 2008년 217ha, 2009년 313ha, 2010년 534ha이었다가 2011년 1,082ha로 크게 증가하였다. 시도별 재배면적은, 전북이 254ha로 가장 많았고, 충남 186ha, 전남 169ha, 경북 157ha, 충북 118ha, 경기 90ha, 경남 58ha, 강원 47ha, 제주 4ha 순이었다. 특히 2010년부터 2011년까지 한 해 동안 블루베리 재배면적이 크게 증가한 것은 각종 언론매체에서 블루베리 기능성에 대한 홍보와 소비자의 인식 증가와 더불어 새로운 소득 작물로 농가 수요가 확대되었기 때문이다. 이는 블루베리 묘목의 수입이 2009년 327천주에서 2010년 702천주로 크게 증가한 것으로도 알 수 있다. 아울러, 국내로 수입되는 냉동과, 건조과의 수입량도 큰 폭으로 증가하였다. 냉동 블루베리 수입량은 2009년 812톤에서 2010년 4,700톤으로 대폭 증가하였는데, 주요 수입 국가는 미국(3,931톤), 캐나다(557톤), 프랑스(70톤), 태국(18톤), 중국(16톤) 등으로 주스 등 가공품 시장의 수요 증가에 따른 것이다. 건조 블루베리의 수입도 2009년 14톤에서 2010년 54톤으로 증가하였다. 2011년 국내산 블루베리 가격은 생과 1kg에 40,000~50,000원선이었으나 35,000원에 판매하는 농장도 있었고, 냉동과를 62,000원도 판매하는 농장도 있었다. 미국 오레곤 주에서 생산한 블루베리 생과가 금년 7월부터 91톤에서 227톤 정도 수입될 것으로 예상된다. 블루베리의 국내 생산량이 많아지고 수입까지 되면, 농업인들은 더욱 품질 좋은 과실을 생산하도록 노력해야 하고, 잼, 식초, 와인 등의 가공식품 외에 과자, 케익, 머핀 등 베이커리용으로 많이 소비되도록 하며, 지역의 다른 상품들과 연계하여 찾아가고 싶은 관광 개발 등으로 소비 촉진을 위해 고심해야 할 것이다.

  • Cosmetics are products used over long periods by the public, and their safety is very important. Contact dermatitis induced by cosmetics is the result of an inflammatory response of the skin to direct irritancy. The initial event that this inflammatory response is observed is the release of pro-inflammatory cytokines. In this study, the anti-inflammatory activities of extracts from Korean herb medicines were investigated using RAW264.7 macrophage. Among the fifty one extracts tested, the ethanol extracts from Biotae Orientalis Folium, Biotae Orientalis Folium (roasted), Cyperi Rhizoma, Nepetae Spica, Benincasae Semen, Dioscoreae Rhizoma, Dioscoreae Rhizoma (roasted), Mori Ramulus, Pini Ramulus and Alismatis Rhizoma reduced the cytotoxicity and inhibited the productions of Nitric oxide (NO) and cytokines such as interleukin (IL)-1${\beta}$, IL-6 and tumor necrosis factor (TNF)-${\alpha}$n lipopolysaccharide (LPS)-induced RAW264.7 macrophage. Additionally, they didn't induce the skin irritation when tested the human patch test. Overall, the result of this study suggests that the extracts of the ten Korean herb medicines are useful cosmetic agents for preventing the skin irritation.
