2006년 국내 각 지역으로부터 수집된 재래종옥수수 유전자원을 관행방법에 의해 파종하고 주요특성별로 분포도를 살펴본 결과는 다음과 같다. 1. 수집된 유전자원에 대한 발아율은 대부분 80∼100%이상의 분포를 보였으나, 일부 수집계통에는 30% 미만의 극히 저조한 발아율을 보였다. 2. 수집자원에 대한 초기생육을 살펴보면 극히 생육이 저조한 것이 40% 정도를 보였고, 극히 우수한 자원은 3%미만으로 나타났다. 3. 간장은 대부분이 150∼199cm범위에 55%가 분포하고 있었으나, l00cm이하가 5%, 250cm이상이 8%로 나타나 수집종간에 큰 차이를 보였다. 4. 주당 분얼수는 1개 미만이 40%의 분포를 보였으나, 일부 수집종에서 2 내지 3개의 분얼수를 보이는 계통이 확인되었다. 5. 개화소요일수는 61∼64일의 범위에서 40%, 57∼60일의 범위에서 30%의 분포를 보였으며, 특히 일부 수집종의 경우 55일 이하의 극조생종도 10% 정도의 분포를 보였다. 6. 이삭길이는 대부분 11∼15cm범위에 60%가 포함되어 있으나, 일부계통에서 5cm미만이 2%, 16∼20cm의 이삭길이도 10%가 분포하였다. Germination ratio on the 300 collected genetic resources showed 80 to 100 percentage, but those of some accessions were very low as below 30 percentage. Early growth phase of most of these lines were very poor while some collected lines were very vigor. Range of stem height showed from 150 to 199cm, but that of some accessions showed below 100cm as five percentage and some of them was over 250cm as eight percentage. Number of tillers per plant appeared less one but some collected lines have two to three tillers per plant. In days to tasseling, some accessions showed more four per plant. Ear length of these accession showed above 60 percentage as 11 to 15cm, while that of some collected lines showed over 10 percentage as 16 to 20cm.

Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

Maize hybrids were planted on April 1, April 25, May 20 and June 15 in 2012, 2013 at the experimental paddy and upland fields in Suwon city , respectively to know changes of growth stage and yield according to different planting time. Maize planting on April 1 was not recommended because total growing days at planting on April 1 was not different with that at planting on April 25 due to many days from planting to emergence over 20 days at planting on April 1. Total growing days were not much different among three planting time after April 25 because days from silking to maturity was lengthened though days from planting to silking was shortened at later planting time. Stalk weight was decreased as planting time was delayed, particularly at planting times after May 20 at paddy field by excess water injury during early growth stage. But, grain yield was not low as in May and June. It is needed to introduce early maturity maize variety as Yanganok at late planting for higher grain yield and enough time for soil preparation for next winter crops

The purpose of this study is to develop the standardized life competency test for adolescences. For this, 114 items were selected from 228 items previously developed by Yun and Seo's study through the indexes of item goodness and statistical criteria. 1,908 middle and high school students were sampled nationwidely. The coefficients of Cronbach α and construct validity were high, and suitability indexes of item factor structure were high. The concurrent validity with youth activity competency scale was verified. As a result of standardization process, the Life Competency Scale with 6 life competencies, 19 life skills and 114 items was developed. The norm table was made in terms of total group, gender, and school level. The norm groups marked the highest scores in interpersonal relationship area among competencies and life skills. The scores of girls recorded significantly higher than those of boys in most life competencies and life skills except in emotional regulation skill. There were no differences in school level over life competency and life skill between middle and high school students. Students can get informations about their life competencies easily through this standardized test, furthermore, teachers or parents can provide educational programs to enhance student 's deficient competencies or life skills. Also, the collected data from 'The Standardized Life Competency Scale' tests can be used as basic data for youths to develop programs and to make policy in schools or fields of youth.

This paper describes structural characteristics of three kinds of piezoresistive pressure sensors, which include wheatstone-bridge type, center-boss type and single-element type, fabricated on one-chip by batch process. In order to optimize device dimensions with respect to the desired characteristics, analytical formula and finited-element modeling(FEM) are used in design process. In experiments the pressure sensitivity of wheatstone-bridge type is about 2.2㎷/V·㎪. The fabricated center-boss pressure sensor has improved in the characteristics as linearity at low pressure, and sensitivity is about 2.415㎷/V·㎪. In single-element type with a four-terminal gauge using shear stress, the maximum sensitivity about 0.4㎷/V·㎪ appeared at the center of the diaphragm with the 3:1 of the length : width ratio. this type is very appropriate method to minimize the temperature dependance of the offset voltage and sensitivity, because the fabricated sensors reduce the offset of themal stress and mismatch of piezoresistros as compared with the wheatstone-bridge type.

Mastoparan B (MPB)는 벌독으로부터 정제된 양친매성α-helical 구조를 취하면서 14개의 아미노산 잔기로 구성된 염기성 항균성 펩타이드로서 여러 가지 생물막과 작용한다. 본 연구에서는 우리 나라 연안의 적조 (HABs, harmful algal blooms)를 일으키는 4종의 적조생물 (Alexandrium tamarense, Chattonella catenatum)에 대한 MPB의 살조효과를 조사하였다. MPB의 4종의 적조생물에 대한 살조효과는 31.3㎍/㎖에서 세포의 lysis또는 ecdysis와 같은 형태로 현미경으로 관찰할 수 있었다. 또한 MPB는 C. marina 및 C. polykridorides에 대해서 A. tamarense와 G. catenatum보다 더욱 강한 살조효과를 나타내었다. 이러한 MPB의 HABs에 대한 살조효과연구는 새로운 살조물질을 개발하기 위한 자료가 될 것으로 생각된다. Mastoparan B (MPB), an antimicrobial cationic peptide isolated from the venom of the hornet Vespa basalis, is a basic amphipathic a-helical peptide composed of fourteen amino acid residues. In this study, we have investigated the algicidal effect of MPB against hatmful algae blooms (HABs) casative Alexandrium tamarense, Chattonella marina, Cochlodinium polykrikoides and Gymnodinium catenatum. The algicidal effect of MPB showed in the concentration of 31.3 ㎍/㎖ to 500 ㎍/㎖ against 4 HAB species and observed cell lysis or cell ecdysis by microscopy. MPB reacted more sensitive to C. marina and C.polykrikoides than A. tamarense and G. catenatum. The algicidal study of MPB against HABs will provides much insight into development of new algicidal substances.
