Changes in Nitrogenous Compounds During the Germination of Ginkgo Seeds
Shim, Kyung-Ku,Ahn, Young-Hee 成均館大學校 科學技術硏究所 1986 論文集 Vol.37 No.1
Changes in weights, proteins, and amino acids in embryo and endosperm tissues of gingko seeds were studied at 14 days of germination. Dry weight of embryo increased in some 8 fold while the dry weight of endosperm decreased steeply, Soluble proteins of endosperm increased slightly until 6 day thereafter decreased gradually. Insoluble proteins of endosperm decreased to 14 days. But, the level of insoluble proteins in embryo tissues did not differ much during the ginkgo seeds germination. On the other hand, amino acids in endosperm and embryo slightly increased during germination. Individual amino acids of dormant seeds were compared with those which were germinated for 14 days. Arginine, glutamic acid and proline showed high contain level in gingko seeds. Here reserve nitrogen in the endosperm was utilized for the synthesis of structural components, and soluble compounds for the seedling. The general quantitative metabolic changes that occur during germination of ginkgo seeds are comparable to those known for other plant seeds.
Analysis on Reports of Statistical Testings for Correlation and Regression
조동숙,김증임,정재원,안수희,박소미,박혜숙 한국여성건강간호학회 2008 여성건강간호학회지 Vol.14 No.3
Purpose: This study aimed to examine the accuracy and adequacy of research papers reporting statistical testings for correlation and regression. Method: Original research articles utilized correlation and regression analysis were reviewed from the Korean Journal of Women Health Nursing published from the year 2004 to 2006. Thirty-six papers were evaluated in accordance with formatted criteria in respect to an inclusiveness of research title, accuracy of statistical methods and presentation styles, and errors in reporting statistical outcomes. Result: Thirty articles (83.3%) utilized Pearson's correlational analysis, and ten articles did regression analysis. Lack of accurate understanding and interpretation of the statistical method was a main fault. Basic assumptions and diagnostic testings for each statistical method were not performed or described in most of the studies. Some points like consistency of research questions with statistical methods and criteria for sample size were still left out in part. Details of the presentation in the reporting of outcomes were not complied with the guidelines, which need careful concerns of the writers. Errors in English of result tables were found in more than one third of the tables. Conclusion: The outcome would be reflected in the submission guidelines for future writers. To reach the level comparable with internationally recognized nursing journals, concrete knowledge to apply statistical methods should be ensured in the processes of submission, reviews, and editing.
