Objective: This study was performed to compare knowledge of and expectations for traditional medicine between Korean, Chinese and Taiwanese, to figure out whether these factors influence the intention to use traditional medical treatment in the future. Methods: One-hundred ninety-nine Korean, eighty-five Chinese, and one-hundred seventy-four Taiwanese subjects responded to the survey. A one-way ANOVA was performed to compare experiences of traditional medical treatment, knowledge of both traditional medicine and western medicine, expectations for traditional medicine, and future intention to use traditional medical treatment. Multiple regression analyses were also performed to evaluate a possible correlation between the other factors and the intention to use traditional medical treatment in the future. Results: The experiences of traditional medical treatment were in the order of Taiwanese, Korean, and Chinese, from more frequent to less frequent. Chinese had more knowledge of traditional medicine compared to Taiwanese and Koreans, and the expectations for traditional medicine were in the order of Chinese, Korean and Taiwanese, from higher to lower. The intentions to use traditional medical treatment in the future were in the order of Korean, Chinese and Taiwanese, from more to less. Multiple regression analyses showed that experiences of traditional medical treatment, knowledge of traditional medicine, and expectations for traditional medicine were associated with the intention to use traditional medicine in the future in Korean and Taiwanese, but not in Chinese. Only the expectations for traditional medicine were associated with the future intentions to use traditional medical treatment in Chinese. Conclusions: These findings suggest that Korean and Taiwanese may need to improve their knowledge of traditional medicine whereas Chinese need to link their knowledge of traditional medicine with the intention to use it in the future. Understanding the characteristics of traditional medicine would probably contribute to enhancing the intentions to use it more.

This study explores the applicability of social capital theory in IT project management. Specifically, an empirical model is developed using different types of leadership competencies (emotional, cognitive, and social) as independent constructs impacting IT project performance. Social capital shared among team members are measured and placed as a mediating construct between leadership competencies and performance. Using PLS analysis of 120 data points collected through a survey of IT project participants in two large electronic manufacturers, direct and indirect impacts of leadership competencies are explicated. Research results reveal that emotional leadership competency seems to directly influence the project performance but not through team social capital, while social leadership competency seems to indirectly influence the project performance through team social capital but not directly onto the project performance. Cognitive leadership competency is the only leadership competency that maintains direct and indirect influence on project performance. Total effect of cognitive competency on project performance is almost two times larger than the total effect of emotional leadership competency and six times larger than the total effect of social leadership competency. Implications of findings are discussed at the end, and further studies are suggested.

1. Objectives: We report the relation between the questionnaire and the health state on the Sasang Constitution. 2. Methods: We carried out a clinical test, in which 2 Oriental medical doctors participated to diagnose health state in each Sasang Constitution with 239 subjects. The subjects were divided into 3 subgroups, which are allocated to healthy group, poor health group and disease group. 3. Results: We extracted 4 questions for Taeeumin, 5 questions for Soyangin and 3 questions for Soeumin from the whole 98 questions respectively. Soyangin and Taeeumin share a same question that shows significant difference by health status. For the statistical analysis, we used a Chi-square test. As a result, we found out that Taeeumin showed different distributions of answers in direct/indirect characteristic, perspiration, frequent urination, regular defecation. According to the health status Soyangin showed the different distribution of the answers in color of urination, frequent urination, mouth dryness, abnormal perspiration, discomfort of head. Soeumin showed the different distribution of the answers in cold and chilly feel of abdomen, digestion status and cause of digestion problems when body condition gets worse. 4. Conclusions: This is the first work which reports the relatedness between Questionnaire and Health State in each Sasang Constitutions by an objective clinical test. We found out that several questions have different distributions by health status in each Sasang Constitution. These extracted questions are categorized not only by Wansilmoobyung(완실무병), but also by other symptoms and body status.

Objectives : The aims of this study were to evaluate a blister caused by cupping. Methods : We searched relevant case reports, survey, and review articles using databases of online bibliography. Results : 1. The fluid in the blister caused by cupping therapy is normal substance by laboratory analysis. The fluid has no signs of infection in the culture, Gram stain, or tissue biopsy 2. In histological finding, the blister caused by cupping therapy is made by dermo-epidermal seperation at subcellular level. Suction blistering was neither inflammatory nor autolysis activation of lysosomal hydrolases. 3. Blistering times directly, related to suction pressure. Suction blister formation time is accelerated in older subjects compared with younger individuals and higher temperature was more susceptable to the blister compared with lower temperature. The flexor aspect of forearm is a easy site for suction blister formation compared with leg and abdominal site. 4. Blister caused by cupping therapy is treated by regular and judicious changes of sterile dressing over several weeks. The vesicles healed well and left no visible scar. Conclusions : Blister caused by cupping therapy is artificially controlled by doctor's therapeutic purpose. Blister is not histologically injurious to health and the blister is a natural concomitant after cupping therapy.

작은 크기 다양한 입출력 포트 등의 많은 이점으로 PCB 회로기판에서 볼그리드배열(BGA) 방식의 기판이 사용되고 있다 하지만 BGA 기판 내부 기포는 기판의 성능을 떨어뜨리고 실패를 야기한다 자동적으로 X-ray 영상에서 기포를 검출하기 위해서 본 논문에서는 국부 영상 명암 변량 측정 방법을 이용한 새로운 덩어리 검출기를 제안한다 국부 영상 명암 변량의 활용은 영상의 밝기 기포의 모양, 기포의 위치 및 부품간의 간섭등에도 연산 결과에 영향이 적은 불변성을 가진다. 또한 박스 필터의 다양한 사이즈를 적용하여 다양한 크기의 영상을 분석하므로 결과적으로 제안한 덩어리 검출 필터는 기포의 다양한 크기에 도강력하다. 실험 결과는 제안한 기법이 정상 부위를 비정상 부위 로보이는 확률false-ratio)을 낮게 유지하면서 기포 검출률을96.104% 까지 높일 수있음을 보인다.

Due to the advantages of small sizes, more I/O ports, etc., Ball Grid Array (BGA) has been used in the production of printed circuit board (PCB). However, BGA voids can degrade the performance of the board and cause failure. To automatically detect the voids in X-ray image, a novel blob filter that makes use of the local image gradient magnitude is proposed in this paper. The utilization of the local image gradient magnitude makes the proposed filter invariant to the image brightness, void shape, void position, and component interference. Furthermore, different sizes of box filters are employed to analyze the image in multi-scale, and as a result, the proposed blob filter is robust to void size. Experimental results show that the proposed method can obtain void detection accuracy up to 96.104% while keep low false ratio.

기존 보고된 바에 의하면 한국 자생 버뮤다그래스는 군집 내에서 형태학, 생육 특성, 세포학적 특성에 대해 유전적으로 매우 다양한 변이를 보여주었다. 버뮤다그래스의 염색체 수와 핵 DNA 량에 따르면 배수성 수준의 범위가, 3배 체(2n=3x), 4배체(2n=4x), 5배체(2n=5x), 6배체(2n=6x)로 나타났었다. 본 연구에서는 한국에서 휴면이 유도되는저온과 짧은 일장에 대한 항산화효소(superoxide dismutase, catalase, peroxidase, ascorbate peroxidase)의 다양한 반응과 각 버뮤다그래스 세포형의 세포막 안정성을 조사하였다. 모든 항산화효소는 휴면 기간동안 높게 나타났으나, 과산화수소를 물과 산소 분자로 변환시키는 헴기를 함유한 카탈라제는 6배체 버뮤다그래스를 제외한 세 개의 세포형에서 휴면이 개시되기 전에 활성화되었다. 상대적으로 세엽이며 생육속도가 빠른3배체와 4배체는 superoxide dismutase와 peroxidase 효소의 활성이 증가됨을 확인하였다. 수산기를 가진 라디칼에 의해 손상을 받은 세포막에서 지질과산화의 산물인 말론디알데히드(MDA)는 온도가 감소함에 따라 모든 세포형에서 증가되었고, 방어적인 항산화효소를 더 갖고 있는 3배체와 4배체는 MDA 생산이 현저하게 더 낮게 나타났다. 전해질 유출은 5배체와 6배체에서 더 높았던 것과 유사하게, 저온이 적용될 때 외견상으로 세포막에 더 손상을 받는 것 같았다. 실험 결과, 서로 다른 세포형(cytotype)의 항산화 반응은 유전적으로 특이적이며, 이는 버뮤다그래스에서 저온 저항성과의 연관성을 분자 수준에서 더 연구하는 것이 필요하다.

Korean bennudagrass collections showed diverse genetic variations in their morphology, growth habit, and cytological aspects. Chromosome number and nuclear DNA content of the bennudagrasses indicated a ploidy level ranging from triploid (2n=3x) to hexaploid (2n=6x). In this study, we investigated the different responses of antioxidant enzymes (superoxide dismutase, catalase, peroxidase, ascorbate peroxidase) and cell membrane stability of those bennudagrass cytotypes to lower temperature and shorter day length, which meets a dormant induction in Korea. All the antioxidant enzymes were found to be higher during dormant stage, while the heme-containing catalase which converts hydrogen peroxide ($H_2O_2$) to water and oxygen molecules was activated before dormant initiation in the three cytotypes except for hexaploid bennudagrass. The triploid and tetraploid which exhibited relatively finer leaves and a rapid establishment speed were found to show increased activities of superoxide dismutase and peroxidase enzyme. The malondialdehyde(MDA) which is a product of lipid peroxidation in the cell membrane damaged by the hydroxyl radical was increased in all cytotypes as temperature declined, and tri- and tetraploids which had more protective antioxidant enzymes demonstrated a significantly lower MDA production. Similarly electrolyte leakage was higher in penta- and hexaploidy, seemingly more damage to cell membrane when low temperature was implemented. Results indicated that antioxidant responses of different cytotypes were genetically specific, which needs to be investigated the relevance with the low temperature tolerance in the bermudagrass further at the molecular level.

Objectives : To understand the strength and weakness of traditional warm needle acupuncture based on existing research outcomes in Korea mostly and to suggest how to build the desirable warm needle acupuncture apparatus by overcoming demerits of traditional and currently existing ones. Methods : We searched warm needle relating papers in Korean with the key words of '온침, 화침, 열자극' by using DBpia, Journal of Korean Oriental Medical Society, Journal of Korean Acupuncture & Moxibustion Society and Journal of Society for Meridian and Acupoint. Degree dissertations in Korean were also searched with the same words through the search engine of Library of Kyung Hee University. We also searched with words of 'warm, thermal, heat, needle, acupuncture, temperature' via Pubmed and found a small number of English written papers and large number of Chinese written ones. To find english translated version of those papers, we googled with the same words with no success. Results : About 20 papers on warm needle acupuncture written in Korean were found and analyzed with respect to experimental factors that affected the thermal properties or the amount of heat stimulus of the acupuncture. More rigorous descriptions seemed to be required on the insertion depth, duration and manipulation of warm needle treatment. A basic heat transfer model was presented for the clarification of heat loss through the needle of warm needle acupuncture. Environmental factors such as air flow on the properties seems to be considered for the warm needle acupuncture. Conclusions : Papers on warm needle acupuncture were reviewed and analyzed based on their thermal properties and tools such as needles and moxa cones. Several suggestions were made on the descriptions relating the properties. Necessary specifications were introduced to aim modernized warm needle systems.

The influence function is used to develop criteria to detect outliers in discriminant analysis. We derive the influence function of observations that estimate the the misclassification probability in discriminant analysis for three groups. The proposed measures are applied to the facial image data to define outliers and redo the discriminant analysis excluding the outliers. The study proves that the derived influence function is more efficient than using the discriminant probability approach.

A study was undertaken to examine the effect of the addition of job's tears(Coixlachryma-jobi L.) chungkukjang(soybeanfermented food) and wheat bran powder on quality attributes of pound cakes. Job's tears chungkukjang and wheat bran powder was added to the batter at a ratio of 10, 12.5 and 15% respectively. The antioxidant activity was estimated by DPPH free radical scavening activity, the total phenolic compounds content and flavonoid content in job's tears chungkukjang & wheat bran powder and pounds cakes. Antioxidative activity was highly correlated with the total phenolic and total flavonoids contents of job's tears chungkukjang and wheat bran pound cakes respectively(r=0.9671, r=0.8335). The quality characteristics of job's tears chungkukjang powder and wheat bran powder pound cakes were estimated in terms of the specific load volume, hardness, hunter value of crumb and crust and sensory quality of cakes. The specific volume were increased significantly with increasing substitution level of job's tears chungkukjang and wheat bran powder(p<l0.01). The lightness were significantly decreased with increases in job's tears chungkukjang and wheat bran powder of pound cake crust and crumb(p<0.01, p<0.01). The hardness, chewiness and gumminess were tended to reduce, while cohesiveness with increase in both of powder. The consumer acceptability score for 10~15% job's tears chungkukjang and wheat bran powder pound cakes ranked significantly(p<0.01) higher than those of the other groups in taste, flavor and overall preference. This results showed that job's tears chungkukjang and wheat bran powder are a good ingredient to increase consumer acceptability and the healthy.

스텔스 기능성 섬유의 위장은 주간의 경우, 육안 및 망원경 관측에 의해 결정되며 주변자연환경 color matching과 패턴이 핵심 스텔스 요인으로 구성되고, 가시광선 영역 스텔스로 표현할 수 있으며, 군 위장 체계에 있어 기본이 되는 기술 분야로 모든 군 위장제품에 활용되는 필수적인 기술 분야이다. 따라서 가시영역의 위장은 다양한 색상의 위장포와 포의 펀칭 등에 의한 파형특성을 부여하고 주위환경과 특성 조화를 이룸으로써 대상을 위장한다. 주요인자는 색상별 색도, 색차이다. 야간 위장은 근적외선 관측 장비의 탐지에 의해 결정되며 주변자연환경 NIR 반사율과 위장제품의 NIR 반사율 저하/제어기술이 핵심 스텔스 요인으로 구성되고, 근적외선(NIR) 영역 스텔스로 표시할 수 있으며, NIR 스텔스는 대개의 경우 기본적으로 섬유제품이 NIR 영역에서 높은 반사율을 나타내므로 NIR 반사율 저하/제어기술이 핵심이라 할 수 있다. 따라서 근적외선 영역(600~1250nm)의 적외선 반사특성을 산림지역의 반사특성과 조화시켜 위장효과를 부여한다. 위장포에서는 적외선 흡수 색소를 사용하여 적절한 반사특성을 나타나게 해야 한다. 위장용섬유가 detector의 탐지에서 벗어나려면 현재 700~1250nm의 근적외선파장영역에서 주변환경과 유사한 반사율을 지녀야한다. 이에 본 연구에서는 "숲 연구소" 및 서울대학교 "지반공학연구실"의 자문을 받아서 우리나라에서 가장 많이 존재하는 자연환경시료를 선정하여, 선정된 시료의 근적외선영역에서의 반사율을 분석하였다. 자연시료는 산간, 해안, 평야지형으로 각각 구분하여 주변 자연지형에 따른 자연시료의 근적외선영역의 반사율값을 비교하였다. 북한산에서 산간지형의 시료를 채취하였고, 해안지형의 시료는 강화도 동막해수욕장 부근, 평야지형의 시료는 인천 강화도 평야지역에서 채취하여 분석하였다. 비교분석한 지형별 자연시료의 근적외선 반사율값의 데이터베이스구축을 통하여 기존의 위장복과의 비교 적용 및 차후 개선사항 등을 검토하고자 한다.

축산폐수 혐기소화 유출수 중의 생물학적 난분해성 유기물의 분해를 위하여 오존 기반의 고도산화 기술을 적용하였다. 배출수의 COD 및 색도는 각각 9200~9500 mg/L 및 0.384 (400 nm)이고 1/10 희석하여 실험에 사용하였다. 공급 오존은 버블의 크기가 $13{\mu}m$인 마이크로버블 오존과 $105{\mu}m$인 일반 오존버블과의 차이를 고찰하였다. 마이크로버블 오존을 사용함으로써 오존의 용해도와 라디칼 생성량이 증가되었고 일반 오존버블에 비하여 COD 및 색도의 제거효율이 각각 85% 및 26% 향상되었다. 마이크로버블을 포함한 $O_3/UV$, $O_3/H_2O_2$, $O_3/UV/H_2O_2$의 조합을 비교한 결과 오존 단독 처리에 비하여 색도 제거율이 5~10% 정도 증가되었으며, 오존에 비하여 UV나 $H_2O_2$의 색도제거에 대한 기여가 크지 않음을 알 수 있었다. 반면 COD에 대해서는 $O_3/UV/H_2O_2$ 적용시 오존 단독에 비하여 2배 이상 제거율이 증가하였으며 UV보다는 $H_2O_2$의 기여도가 더 컸다. 한편 마이크로 오존의 사용시 증가된 용존오존 및 라디칼 활성으로 인하여 오존 공급을 중단한 후에도 UV 또는 $H_2O_2$를 적용함으로써 추가적인 COD 분해 효과를 지속적으로 유지할 수 있었다.

Ozone-based advanced oxidation was applied for the treatment of anaerobic digestion effluent of livestock wastewater. Initial COD and color value were 930 mg/L and 0.04, respectively, and the 1/10-diluted wastewater was used for the study. The treatment characteristics were compared between the conventionally generated ozone ($105{\mu}m$) and microbubbled ozone ($13{\mu}m$). The use of microbubbled ozone improved the removal of chemical oxygen demand (COD) and color by 85% and 26%, respectively, compared with the conventionally bubbled ozone. The application of microbubbled $O_3/UV$, $O_3/H_2O_2$, $O_3/UV/H_2O_2$ combinations resulted in 5~10% higher color removal than ozone alone, which implies that the contribution of UV or $H_2O_2$ is not significant in color removal. On the other hand, COD removal could be increased two folds compared with ozone alone through $O_3/UV/H_2O_2$ combination. The contribution of $H_2O_2$ was bigger than UV for COD removal with microbubbled ozone. Due to the enhancement of dissolved ozone and radical activity, the microbubbling enabled us to additional COD removal even after stopping ozone supply in the presence of UV or $H_2O_2$.

Purpose: The main purpose of this study was to describe the relationship of mothers' parenting attitude as perceived by the child to self-esteem, and school adjustment of school age children with Tetrology of Fallot (TOF). Methods: In this study a self-administered questionnaire survey was used to collect the data. The participants included 38 children who were registered in a pediatric cardiology clinic in one tertiary medical center. Their ages were between 11 and 15 years. They were diagnosed with TOF, and had no other congenital problems. Data were collected from November 1 to November 30, 2009. After obtaining telephone consent from the mothers and children, questionnaires were mailed to 64 participants and 38 questionnaires were returned. Data were analyzed using Statistical Package for the Social Sciences (SPSS) WIN 15.0 version. Results: There was a significant correlation between perceived parenting attitude, self-esteem, and school adjustment of children with TOF. Conclusion: Children who perceive their mothers' parenting attitude to be more positive also report higher self-esteem and better school adjustment. These findings are similar to other studies done with healthy school age children. However, parents of children with TOF may require different parenting approaches to foster positive self-esteem and school adjustment.

Cellulose섬유의 염색시 섬유가 물속에 침지되면 섬유표면은 음전하가 형성되어, 용액 속에서 음이온으로 존재하는 염료와의 반발력으로 인해 염료가 섬유에 접근하기가 어려워지며 따라서 염색이 원활하게 이루어지지 않는다. 그러나 염욕에 염화나트륨(sodium chloride, NaCl)이나 망초 즉, 황산나트륨(Glauber's salt, sodium sulfate, Na2SO4)과 같은 전해질을 첨가하면, 양이온인 sodium 이온이 섬유표면과 음이온 염료사이의 반발력을 감소시킨다. 따라서 음이온의 염료는 섬유표면에 접근할 수 있고, 고유한 인력으로 염색이 가능하게 된다. 현재 Cellulose섬유의 상업적인 반응성염료 염색공정뿐만 아니라 최근 연구에서는 전해질 중 대부분 분말망초를 대부분 사용하고 있다. 그러나 분말망초는 별도의 용해과정이 필요할 뿐 아니라, 과량 사용시 용해되지 않은 분말이 섬유 표면에 흡착될 경우 불균염을 초래할 우려 등의 단점이 있다. 이와 같이 작업효율성을 향상시키고 염색을 효율적으로 진행시키기 위해 최근 액상형의 망초가 도입되고 있다. 이 연구에서는 분말 및 액상 망초를 조제로 사용하여 3종류의 Cellulose섬유를 반응성염료로 염색하였다. 담색, 중색, 농색 3가지 염료 농도에 대해 투입하는 망초의 type에 따라 각각의 Cellulose섬유별 균염성 정도에 대하여 비교해 보았다.

율무청국장이 고지방식이를 섭취한 흰쥐의 체중 및 체지방, 혈청과 간, 분변의 지질농도 및 혈당농도 등에 미치는 영향을 조사하고자 SD계 수컷 흰쥐를 대상으로 고지방식이 (D12492, 45 kcal fat)에 청국장 및 율무청국장(율무 함량 20%) 분말을 각각 10%, 20%씩 중량비로 첨가하여 5주간 급여한 결과는 다음과 같다. 체중증가량은 군별 유의성이 없었으나 식이효율은 고지방식이 대조군에 비해 율무청국장 분말 20% 첨가군에서 유의적으로 낮았으며(p<0.05), 지방조직의 무게는 실험군 간에 유사한 수준을 나타내었다. 배변량 및 간 조직의 총콜레스테롤과 중성지방 함량은 군별 유사한 경향을 나타내었으며, 분변의 총콜레스테롤 함량은 군별 유의적 차이가 없었으나 중성지방 함량은 대조군에 비해 실험식이 첨가 수준에 따라 유사하거나 증가하는 경향을 보였다. 혈청 총콜레스테롤, HDL-콜레스테롤 및 LDL-콜레스테롤 농도는 군별 유의적인 차이가 없었으나 동맥경화지수와 심혈관위험지수는 청국장 분말 10%, 20% 및 율무청국장 분말 20% 첨가군에서 대조군보다 유의적으로 낮았으며(p<0.05), 중성지방 농도는 대조군에 비해 청국장 및 율무청국장 분말 20% 첨가군에서 유의적으로 감소하였다(p<0.05). 한편, 혈당 농도는 실험군 간에 유의적인 차이가 없는 것으로 드러났다. 이상에서 율무청국장 식이는 식이효율의 감소, 중성지방의 배설량 증가, 그리고 혈청 중성지방 농도의 감소 및 동맥경화지수와 심혈관위험지수의 감소 등의 효과를 확인할 수 있었다.

This study was performed to investigate the effects of Cheonggukjang added with Job's tears (CAJT) on antiobesity and lipid profiles on diet-induced obese rats. Male Sprague-Dawley rats were fed high-fat diet only (A, control), and high-fat diet with Cheonggukjang powder 10% (B), CAJT powder 10% (C), Cheonggukjang powder 20% (D), CAJT powder 20% (E) for 5 weeks. Body weight gains were similar in the experimental groups, but FER was significantly lower in the group E than group A (p<0.05), and adipose tissue weights in groups with Cheonggukjang and CAJT powder were similar to those in the group A. The lengths of small intestine were significantly longer in the groups B, C, D, and E than the group A (p<0.05). Hepatic concentrations of total cholesterol (TC) and triglyceride (TG) were similar to each other. Fecal weights were not significantly different among the groups. Fecal TC concentrations were similar in the experimental groups, but fecal TG concentrations were greatly increased in the groups B, D, and E (p<0.05). The serum TC, HDL-C and LDL-C levels varied slightly among the groups, but serum TG levels were decreased in the group D and E than in the group A (p<0.05). The AI and CRF were marginally decreased in the groups B, D, and E than in the group A (p<0.05). However, blood glucose levels were not significantly different among the groups. From the findings, it had shown that Job's tears Cheonggukjang could improve lipid profiles.

In this paper, we designed 2D, 2.5D cloth design system and a 3D cloth animation system. They make the 3D cloth animation possible by using coordinate points extracted from 2D and 2.5D cloth design system in order to realize a system that allows customers to wear clothes in the virtual space. To make natural draping, it uses for description the mesh creation and transformation algorithms, path extraction algorithm, warp algorithm, and brightness extraction and application algorithms. The coordinate points extracted here are received as text format data and inputted as clothing information in the cloth file. Moreover, the cloth file has a 2D pattern and is realized to be used in the 3D cloth animation system. The 3D cloth animation system generated in this way builds a web-based fashion mall using ISB (Internet Space Builder) and lets customers view the clothing animation on the web by adding the animation process to the simulation result.

Job's tears (Coixlachryma-jobi L.) and Chungkukjang (soybean-fermented food) were abundant source of phenolic compounds. In this study, almond cookies were prepared with different concentration(5%, 10%, 15%), of Job's tears Chungkukjang powder. The total phenolic contents were measured by the Folin-Ciocalteu method, total flavonoids contents were measured, and antioxidant activities were evaluated by DPPH assay. Antioxidative activity was highly correlated with the total phenolic and total flavonoids contents of Job's tears Chungkukjang almond cookies (r=0.867, r=0.647). In addition, the quality characteristics of the Job's tears Chungkukjang almond cookies were estimated based on the bulk density and pH of the dough, spread factor, color, texture profile analysis, proximate composition, and sensory evaluations. The spread factor, hardness, a value and b value, total polyphenolic contents, and DPPH free radical scavenging activity of cookies significantly increased with increasing content of Job's tears Chungkukjang powder (p<0.01), whereas the L values of the cookies decreased with the increasing Job's tears Chungkukjang powder content (p<0.05).

벼의 염기서열 분석이 완료됨에 따라 유전자의 세포내 기능을 밝히기 위한 기능유전체 연구가 활발히 진행되고 있다. 이를 위해 효율적으로 아그로박테리움을 이용해 원하는 유전자를 식물체 내로 형질전환을 하기 위한 노력은 지금도 계속 진행되고 있다. 본 실험에서는 캘러스를 유기한 후 아그로박테리움을 이용해 접종하는 기존의 방법과 달리, 성숙 종자를 소독한 후 2,4-D가 포함된 액체배지에 24시간 침종하여 배 부분이 발아하기 시작하는 종자를 이용해 바로 아그로박테리움을 접종하여 체세포변이의 발생을 최소화하고 유전자를 포함하고 있는 아그로박테리움이 식물 조직내로 침투할 수 있는 효율을 증가시키며, 그 후 캘러스를 유기하여 재분화 시킴으로써 형질전환 식물체를 얻는 방법을 새롭게 수립하였다. 배양과정 중 공동배양 배지에 아그로박테리움 성장억제물질인 silver nitrate와 항산화 물질인 DTT를 첨가하여 공동 배양 기간을 7일 이상으로 늘림으로써 벼 형질전환효율을 증가시킬 수 있었고, PCR 분석을 통해 원하는 목표 유전자가 형질전환체에 안정적으로 도입이 되는 것도 확인할 수 있었다. 또한, 이 방법은 형질전환 효율이 낮은 일품벼와 같은 품종에도 적용할 수 있을 것으로 판단된다. 이러한 결과를 종합해 볼 때, 본 실험을 통해 얻어진 새로운 공동배양 방법은 우수한 농업적 형질을 가진 벼 육종 소재 및 품종 개발시 효율적으로 이용할 수 있을 것으로 생각된다.

Rice is the most important crop as a model plant for functional genomics of monocotyledons. Rice is usually transformed using Agrobacterium tumefaciens. However, the transformation efficiency using previous method is still low. In this study, we established a new method by modifying the general Agrobacterium protocol especially in the inoculation and co-cultivation step. We directly inoculated Agrobacterium containing a CIPK15 gene under the control of CaMV 35S promoter and NOS terminator in the pCAM1300 vector into the pre-soaked seeds in N6D media for 24 hours. After 7 days of culture at $25^{\circ}C$, calli were formed on seeds cultured on the co-cultivation medium containing an antioxidant compound (1 mM dithiothreitol) and of Agrobacterium growth-inhibiting agent (3 mg/L silver nitrate). We obtained 35 and 22 transgenic plants in rice cultivars, Gopumbyeo and Ilpumbyeo, with increase of transformation efficiency by 30.4% and 22.6%, respectively compared to the general transformation method. The new method in this study would lead to reduction of substantial labor and time to generate transgenic plants.
