This study was made to understand a hypoglycemic action of the fat soluble fraction of Panax ginseng C.A. Meyer in streptozotocin induced diabetic rats by determining the activities of several enzymes related to carbohydrate and lipid metabolism as well as several blood component levels such as glucose and ketone bodies, and non-esterified fatty acids. Albino rats (Sprague Dawley, 170-200g, 3) were injected once with 70mg streptozotocinhg body weight intraperitoneally and fed with ordinary diet for 7 days, and then the fat soluble fraction (5 mg~20 mg/day/rat) was injected intraperitoneally once a day for three days to rats having high blood glucose level over 340 mg/100ml. After a final injection of the fat soluble fraction, rats u.ere starved for 16 hours followed by the analysis of blood serum and liver enzymes. It was found that increased levels of glucose, ketone bodies and free fatty acids in streptozotocin induced rats were decreased appreciably by administration of the fat soluble fraction. However, the amount of administered fat soluble fraction did not show any significantly different hypoglycemic action. Decreased activities of glucokinase, phosphofructokinase, pyruvate kinase, 6-phosphogluconate dehydrogenase and acetyl CoA carboxylase of the liver of streptozotocin induced diabetic rats were greatly modified suggesting that a hypoglycemic action of the fat soluble fraction was also appreciable as ginseng saponin fraction. We also compared a hypoglycemic action of the fat soluble fraction prepared from American ginseng and Chinese ginseng with that of Korean pain ginseng. 핀o significant difference of the hypoglycemic activity was observed between the above ginseng fat soluble fractions, suggesting that a study of the fat soluble fraction might be one of the most interesting subjects relating to diabetic hyperglycemia in the near future.

Purpose: The purpose of this study was to construct and test a structural equation model for pressure ulcer prevention action by clinical nurses. The Health Belief Model and the Theory of Planned Behavior were used as the basis for the study. Methods: A structured questionnaire was completed by 251 clinical nurses to analyze the relationships between concepts of perceived benefits, perceived barriers, attitude, subjective norm, perceived control, intention to perform action and behavior. SPSS 22.0 and AMOS 22.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factors affecting pressure ulcer prevention action among clinical nurses. Results: The model fitness statistics of the hypothetical model fitted to the recommended levels. Attitude, subjective norm and perceived control on pressure ulcer prevention action explained 64.2% for intention to perform prevention action. Conclusion: The major findings of this study indicate that it is essential to recognize improvement in positive attitude for pressure ulcer prevention action and a need for systematic education programs to increase perceived control for prevention action.

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 paper aims to analyse the inequality and poverty in Malaysia. Malaysia is considered to be a country of high inequality and high poverty according to the Asian Development Bank. To tackle the income inequality and poverty in Malaysia, especially after the incident of ethnic riot in 1969, the government pursued to implement the affirmative action for the benefit of bumiputra. Recognizing the fact that the economic factors are crucial in determining the levels of inequality and poverty, this paper analyses the historical, institutional and cultural factors and evaluates the affirmative action designed to reduce the income gap between bumiputra and non-bumiputra.

This paper examines some questions and issues of the effect of an arbitral award, and discusses about the restriction of the trial level in other separate actions permitted under the existence of grounds of setting aside arbitral award after the amendment of the Arbitration Act in 2016. Because there are no interests of litigation in the action for setting aside arbitral award due to the exclusion of res judicata by provisory clause of Article 35, filing an action for setting aside is not allowed even when the grounds of setting aside exist. If we examine the precedent on possibility of retrial for excluding the outward form of invalid judgement, we can find that the court did not approve the retrial. Therefore, the action for setting aside that which is for excluding the outward form of an arbitral award will not be allowed for filing. On the issue of whether an arbitral award having a ground for setting aside can be an object of the action for setting aside for excluding its outward form or not, the views of scholars are divided. In the case of an arbitral award that has grounds for setting aside, it could be interpreted that the arbitral award would not have a formale Rechtskraft or effect of sentence (bindende Kraft). Even if there is formale Rechtskraft or effect of sentence (bindende Kraft), the significance of existence of action for setting aside arbitral award under paragraph 1 of Article 36 is reduced because other actions separate from arbitration is permitted under the 2016 Act. The amendment of the Arbitration Act in 2016 provides an opportunity to review the position and the role of action for setting aside the arbitral award. It also requires further studies on efficiently treating other actions separate from arbitration. Because the restriction of the trial level of other separate actions can make arbitration active by making arbitration procedures become 3 trial levels from 4 trial levels, it needs to be solved with legislative action. Specifically, if the trial starts at the stage of trial on appeal, it can utilize the strength of both the arbitration and the litigation, playing a chief role in boosting arbitration by removing the problems of action for setting aside and enabling arbitration institutes and the person interested to promote the activation of arbitration.

Purpose: This study was performed to explore levels of stroke knowledge and identify subgroups with lower levels of stroke knowledge among adults in Korea. Methods: A cross-sectional survey was used and data were collected in 2012. A national sample of 990 Koreans aged 20 to 74 years participated in this study. Knowledge of risk factors, warning signs, and first action for stroke were surveyed using face-to-face interviews. Descriptive statistics and decision tree analysis were performed using SPSS WIN 20.0 and Answer Tree 3.1. Results: Mean score for stroke risk factor knowledge was 7.7 out of 10. The least recognized risk factor was diabetes and four subgroups with lower levels of knowledge were identified. Score for knowledge of stroke warning signs was 3.6 out of 6. The least recognized warning sign was sudden severe headache and six subgroups with lower levels of knowledge were identified. The first action for stroke was recognized by 65.7 percent of participants and four subgroups with lower levels of knowledge were identified. Conclusion: Multi-faceted education should be designed to improve stroke knowledge among Korean adults, particularly focusing on subgroups with lower levels of knowledge and less recognition of items in this study.

The effects of phenthyl isothiocyanate(PEIFTC) on xenobiotic metabolizing enzymes and cell kinetics in the target organs for Ν-nirtosobis(2-oxopropyl) amine(BOP)-tumorigenicity were investigated in female Syrian golden hamsters in order to gain the mechanistic insigths into the chemopreventive action of PEITS against BOP-initiated lung and pancreatic carcinogenesis in hamsters. Hamsters were given BOP subcuteneo-usly(s.c.) and/or PEITC by gavage 2h prior to the BOP treatment. Eight and 24h after the PEITC administration, animals were sacrificed for analyzing P450 isoenzymes, glutathine(GSH), glutathione S-transferase(GST) and cell kinetics. The PEITC pretreatment significantly reduced the hepatic P450 isoenzume levels such as CYP2B1 and DYP1A1 which were significantly increased by the BOP treatment. However, PEITC did not affect the CYP levels in the pancreas and lung. Interestingly, the PEITC pretreatment rather lowered the heparic GST and GSH levels, regradless of BOP administration. Proliferating cell nuclear antigen(PCNA)- labeling indices were dose dependently decreased by PEITC in the pancreas acini and ducts, bronchioles, and renal tubules in which the cell replication was significantly affected by BOP. These results thus suggest that PEITC exerts the chemopreventive effects in hamsters by influencing xenobiotic matabolizing phase I enzymes in the liver and regulating cell kinetics in the target organs.
