  • Objectives : In present study, therefore, possible beneficial pharmacological activities of standard potato protein extracts (SPE) were observed on the mild diabetic obese mice. Methods : After end of 12 weeks of continuous oral administrations of three different dosages of SPE 400, 200 and 100 mg/kg, or metformin 250 mg/kg, analyzed the hepatoprotective, hypolipidemic, hypoglycemic, nephroprotective and anti-obesity effects, separately. In addition, liver antioxidant defense systems were additionally measured with lipid metabolism-related genes expressions and hepatic glucose-regulating enzyme activities for action mechanism. Results : All of diabetes and related complications including obesity were significantly inhibited by treatment of SPE 400, 200 and 100 mg/kg, dose-dependently, and they also dramatically normalized the hepatic lipid peroxidation and depletion of liver endogenous antioxidant defense system, the changes of the hepatic glucose-regulating enzyme activities, also changes of the lipid metabolism-related genes expressions including hepatic $AMPK{\alpha}1$ and $AMPK{\alpha}2$ mRNA expressions, dose-dependently. Especially, SPE 200 mg/kg constantly showed favorable inhibitory activities against type II diabetes and related complications as comparable to those of metformin 250 mg/kg in HFD mice, respectively. Conclusions : The present work demonstrated that SPE 400, 200 and 100 mg/kg showed favorable anti-diabetic and related complications including obesity refinement activities in HFD mice, through AMPK upregulation mediated hepatic glucose enzyme activity and lipid metabolism-related genes expression, antioxidant defense system and pancreatic lipid digestion enzyme modulatory activities.

  • Several hydroxylated cinnamic acid derivatives were prepared from the corresponding acids and amino acid residues, and their hypocholesterolemic activities were evaluated in high cholesterol-fed mice. The presence of the double bond in hydroxylated cinnamide derivatives decreases cholesterol-lowering activities and the number of free phenolic hydroxy groups affect greatly the activities. 3,4-Dihydroxy hydrocinnamides obtained from amino acid derivatives containing a hydrophobic side chain such as alanine, valine, phenylalanine, and isoleucine exhibited potent cholesterol-lowering activities.

  • Three occupational safety and health (OSH) activities, one international and two national workshops, were documented as part of OSH activities conducted under the International Labor Organization/Korea Partnership Program in the year 2011-2012. This study aimed to provide information on what the three OSH activities were implemented and how they contributed to the improvement of OSH in Asian countries. The international workshop was useful for the participants to understand a variety of information on OSH as well as participatory action-oriented training (PAOT) approaches at the regional and global levels. The two national workshops were practical for participants to strengthen their knowledge and skills on the PAOT at the enterprise and national levels. The study shows that the three OSH activities contributed to the understanding of the participants on OSH and PAOT, and that the activities promoted the improvement of OSH across countries in Asia.

  • This study was conducted to analyze the effect of information security activities on organizational performance. With this in mind and with the aim of resolving transaction stability in the securities industry, using an organization's security activities as a tool for carrying out information security activities, the effect of security activities on organizational performance was analyzed. Under the assumption that the effectiveness of information security activities can be bolstered to enhance organizational performance, such effects were analyzed based on Herzberg's motivation theory, which is one of the motivation theories that may influence information protection activities. To measure the actual attributes of the theoretical model, an empirical survey of the securities industry was conducted. In this explorative study, the proposed model was verified using partial least squares as a structural equation model consisting of IT service, information security, information sharing, transaction stability, and organizational performance.
