Analogues of the homopyrimidine oiigonucleotide dT,s that contained phosphorothioat¢ bonds of a mixture ofdiastereoisomers or one of tile two stereoisomers (either Rp or Sp) were synthesized. The analogues were mixed under eondition~ conducive to the formation of tripl¢.-.atranded assemblies. The mixtures were characterized by their thermal stabilities (7"1,, values), CD spectra, and gel electropltoresis pattern. The 34-met duplexes containing 15 central purines on one strand attd 15 complementary pyrimidines on the other strand gave no detectable triple helix upon combination with dTt~S~. On the other hand, 34-bp duplexes with dT~sS,, having Rp or Sp, formed triple helix~. This suggests that a sterie factor plays an important role in triple helix formation.

Purpose - This study is a study on the factors affecting job satisfaction of foreign migrant workers (focusing on domestic automobile industry workers) to examine the impact of foreign workers on the corporate management of Korean manufacturers in Korean society. Design/methodology/approach - A survey was conducted on 152 foreign laborers who lived in Korea. First, an exploratory factor analysis was performed to confirm reliability and validity. Second, an multiple regression was conducted based on the reliability and exploratory factor analysis results. Third, the mediation regression by checking the effect of organizational commitment. Findings - The acculturation and organizational fairness were found to have a great influence on job satisfaction, and this study found that perceived acculturation had an effect on job satisfaction through the mediating effect of organizational commitment. In addition, organizational fairness was also found to have an effect on job satisfaction as a mediating effect of organizational commitment. Research implications or Originality - It was to provide meaningful implications for foreign workers in the current Korean labor market. Based on the results, the corporate competitiveness of Korean manufacturers should be further secured.
