Objectives: The purpose of this study is to investigate whether the ethical climate affects the job satisfaction of the clinical dental hygienists. Methods: A self-reported questionnaire was filled out by 207 dental hygienists. The data were analyzed by t-test or one-way ANOVA, multiple regression analysis, and Pearson’s correlation analysis using IBM SPSS Statistics 19.0 program. Results: The factors affecting the job satisfaction of the general and ethical climate were the work experiences, the completion of vocational ethics education, the self interest type, the friendship type, the rule and the procedure type. When working experience and vocational ethics education are completed, self interest type and friend type have improved job satisfaction as the score increases, while job satisfaction is lowered as the rule and procedure type are increased. Conclusions: Since healthy ethical climate correlates with job satisfaction, it is necessary to establish an ethical climate in order to improve the job satisfaction of clinical dental hygienists. Efficient and stable management of ethical climate within dental clinics can be achieved when mutual interests are emphasized and respected rather than obedience is empathized to hospital regulations, procedures and policies.

This study was carried out to investigate the cross compatibility, fertilization and immature ovule culture to gain interspecific hybrid plants between perennial and cultivar in Glycine. 1. Pod survival rate determined perennial Glycine tomentella hihger than Glycine max(L.) as a maternal parent and cross compatibility with cultivar investigated G. tabacina was lower than G. tomentella. 2. Immature ovule culture showed 22% of in virto germination, 4% of callus formation, 71% of no response, and succeeded two normal hybrid plantlets cultured on B5 basal medium supplemented 0.1㎎/ℓ BA and 0.2㎎/ℓ BAP. 3. In observation of initial fertilization after interspecific cross of Glycine, pollen tube germination on stigma and double fertilization were progressed more faster in G. tomentella/G. max than in G. max/G. tometella.
