  • The work-related musculoskeletal disorders have constantly increased since it became an issue in 1996. In 2002, the Government established the risk factors analysis system in order to prevent musculoskeletal disorders. The proclamation by the Ministry of Labor defined eleven spheres of work associated with musculoskeletal disorders. As a result, business proprietors, who have workers engaged in tasks associated with musculoskeletal disorders, are required to conduct the risk factor analysis on a regular basis every three years. However, numerous issues have been raised while carrying out the risk factor analysis in various industries. One of the issues is that even though work sampling is an ideal method in risk factor analysis, most cases have selected extreme task postures, which is judged by an expert, due to limited time. This study will propose the desired direction of the risk factor analysis by comparing task assessment results between work sampling scenes and extreme task scenes.

  • The purpose of this case-control study was to show the relationship between risk factor(Sex, Age, Martial Status, Educational Periods, Family history, Variables of Obesity, Smoking Status, Drinking Status, Past History, Blood Test) and the incidence of stroke. Methods: 788 stroke patients were enrolled as the case group and 450 non-stroke patients as control group from Sep.2006 to Dec.2010. Patients were hospitalized within 30 days after the onset of stroke. Risk factors and warning signs were obtained from personal interview by oriental medicine doctors who used CRF. Results: 1. Age was found to have significant relation with stroke(p<.0001). 2. Martial status(p<.0001, OR=0.44) and educational periods(p<.0001) were both significant risk factor for stroke. 3. As a result of reviewing the influence of family history, it was found to have no significant relation with stroke. Stroke was found to have significant relation with stroke(OR=1.50). 4. Female waist circumference(WC, p<.0001) and female waist-hip circumference ratio(WHR, p<.0001) were risk factors for stroke. On the other hand, male WC and male WHR showed no significant influence on stroke occurrence as an independent risk factor. 5. Both smoking status(p<.0001, current smoker OR=8.95) and drinking status(p<.0001, current drinker OR=2.50, former drinker OR=2.82) were significant risk factors for stroke. 6. As a result of reviewing the influence of past history, transient ischemic attack(p<.0001, OR=8.46), hypertension(p<.0001, OR=4.72), hyperlipidemia(0.0064), diabetes mellitus(p<.0001, OR=3.34), stroke(p<.0001, OR=50.26) were significant risk factors. On the other hand, ischemic heart disease(p=0.2332) was found to have no significant relation with stroke. 7. Increase of WBC, RBC, Platelet, TG, FBS and Cl- level were significant risk factor of stroke, On the other hand, decrease of Hgb, Hct, AST, HDL-chol, LDH, Na+ and K+ level were significant risk factor of stroke. T-chol and ALT level showed no significant influence on stroke occurrence.

  • Background: Diabetes mellitus and hypertension often occur together, amplifying cardiovascular disease (CVD) risk and emphasizing the need for a multitargeted treatment approach. American ginseng (AG) and Korean Red Ginseng (KRG) species could improve glycemic control via complementary mechanisms. Additionally, a KRG-inherent component, ginsenoside Rg3, may moderate blood pressure (BP). Our objective was to investigate the therapeutic potential of coadministration of Rg3-enriched Korean Red Ginseng (Rg3-KRG) and AG, added to standard of care therapy, in the management of hypertension and cardiometabolic risk factors in type-2 diabetes. Methods: Within a randomized controlled, parallel design of 80 participants with type-2 diabetes (HbA1c: 6.5-8%) and hypertension (systolic BP: 140-160 mmHg or treated), supplementation with either 2.25 g/day of combined Rg3-KRG + AG or wheat-bran control was assessed over a 12-wk intervention period. The primary endpoint was ambulatory 24-h systolic BP. Additional endpoints included further hemodynamic assessment, glycemic control, plasma lipids and safety monitoring. Results: Combined ginseng intervention generated a mean ± SE decrease in primary endpoint of 24-h systolic BP (-3.98 ± 2.0 mmHg, p = 0.04). Additionally, there was a greater reduction in HbA1c (-0.35 ± 0.1% [-3.8 ± 1.1 mmol/mol], p = 0.02), and change in blood lipids: total cholesterol (-0.50 ± 0.2 mmol/l, p = 0.01), non-HDL-C (-0.54 ± 0.2 mmol/l, p = 0.01), triglycerides (-0.40 ± 0.2 mmol/l, p = 0.02) and LDL-C (-0.35 ± 0.2 mmol/l, p = 0.06) at 12 wks, relative to control. No adverse safety outcomes were observed. Conclusion: Coadministration of Rg3-KRG + AG is an effective addon for improving BP along with attaining favorable cardiometabolic outcomes in individuals with type 2 diabetes. Ginseng derivatives may offer clinical utility when included in the polypharmacy and lifestyle treatment of diabetes. Clinical trial registration: Clinicaltrials.gov identifier, NCT01578837;

  • Objectives & Method:Based on the statistic from January 2008 to December 2008 include 66-year-old 375 people (159 men, 216 women) who got examined in National Health Insurance Corporation, this study set a goal to establish a new health index by analyzing the relation between the cardio-cerebra vascular disease and risk factor such as obesity, smoking, exercise, alcohol consumption, blood pressure, blood sugar and cholesterol. Results:1) Examine results, health status according to gender;People who are diagnosed as abnormal health status have higher risk for both men and women. As for the detailed diseases, high blood pressure was highest followed by hyperlipidemia and obesity. In case of the women, 96.3% in bone mineral density was highest. 2) Correlation of disease and health risk factors based on gender;Correlation of disease according to gender in the obesity(p<0.001), lipid abnormalities(p<0.001), kidney diseases(p<0.001), chest diseases(p<0.05), osteoporosis(p<0.001) showed a statistically significant difference. The analysis showed that the men have more obesity and lipid abnormalities as well as thoracic disease than the women, but the women have more kidney disease than the men. As for the osteoporosis examine which is conducted only for the women, most of the women were abnormal even though it cannot compare the result according to gender. Obesity(p<0.001), alcohol(p<0.001), smoking(p<0.001) and LDLcholesterol(p<0.001) showed statistical correlation between gender and health risk factor. And only high blood pressure(p<0.001) showed a statistical correlation between gender and risk of cardio-cerebra vascular disease. 3) Risk of cardio-cerebra vascular disease related to health risk factor characteristic;Obesity assessment(p<0.001), alcohol(p<0.05), smoking(p<0.05), blood pressure(p<0.001), glucose(p<0.001) showed correlation between health risk factor and stroke. Drinking(p<0.001), smoking(p<0.05), exercise(p<0.001), blood pressure(p<0.001), LDL cholesterol(p<0.001) showed health risk factor and myocardial infarction. Obesity assessment(p<0.001), smoking(p<0.05), blood pressure(p<0.001), glucose(p<0.001) and showed correlation between health risk factor and diabetes. Obesity assessment(p<0.001), blood pressure(p<0.001) showed correlation between health risk factor and high blood pressure. Conclusion:Therefore, we have to take one step farther after the health examination. In order to prevent and reduce the risk of disease, people have to understand their health status exactly first, and correct their habit with recognizing the amount of risk related to cardio-cerebra vascular disease.

  • Purpose - This study examines whether flight-to-liquidity (FTL) explains the dynamic liquidity risk on stock returns, and whether it has a significant influence on determinants the cross-section of stock returns. Design/methodology/approach - This study suggests a new risk factor, dynamic liquidity hedge portfolio (DLP), to reflect the dynamic impact of liquidity risk on stock returns and the Fama-MacBeth 2 stage regression analysis is employed in order to analyze the data. Findings - First, the DLP factor shows more positive and significant beta for the small or illiquidity stocks. Second, the DLP shows a different influence than SMB (size risk factor), HML (value risk factor), NMP (liquidity risk factor), FTVOL (total volatility factor) in determining the cross-section of stock returns. In addition, the DLP has a statistically significant risk premium of around 5%, which is relatively larger than other risk factors. Research implications or Originality - This study has academic value in terms of newly confirming that the DLP factor has a more significant impact on cross-sectional determination of stock returns than other risk factors by proposing a conditional liquidity factor that can explain the FTL phenomenon.

  • While ginseng is reported to have a wide array of applications, there is growing evidence for its indications in diabetes and vascular disease. A clear connection, however, has not been established between ginseng's composition, dose and its targeted efficacy in humans. We therefore developed and initiated the Korean Red Ginseng Clinical Testing Program for diabetes and vascular function which is an efficacy and safety-based clinical screening model for ginseng. The most efficacious sources, ginsenoside profiles, doses, and modes of administration were examined in sequential, acute, followed by long term, randomized-controlled trials to investigate the efficacy and safety profiles. This review discusses the current state of the clinical research of Korean red ginseng program conducted in Toronto, paving the way for the use of clinically selected ginseng and its ginsenoside fractions in the management of diabetes and vascular diseases.

  • Objectives: This study aimed to determine whether the self-rated health (SRH) could be a risk factor for compulsion. Methods: Data related with compulsion and SRH information were collected from 532 young adults aged over 20 years in South Korea. The distribution of the high and low SRH groups was analyzed using the chi-square test, whereas difference in quality of life (QoL) was analyzed using the t-test. Logistic regression was used to analyze the odds ratio (OR). Results: In the high and low-SRH groups, 44 (28.8%) and 23 (31.5%) men and 24 (10.4%) and 21 (27.6%) women, respectively, were at risk for compulsion (p<.001). For women, the compulsion scores of the low and high-SRH groups, respectively, were 15.8±9.53 and 9.9±8.47 (t=5.071, p<.001). The low-SRH group had higher ORs compared with the high-SRH group among women (OR 3.277, 95% confidence interval 1.699 - 6.321, p<.001) in the original model, and this phenomenon was significant even after adjusting for age and residence type. Conclusions: Low SRH may be a risk factor for compulsion. Further research for improving SRH by developing preventive measures against compulsion is necessary.

  • This paper examines the efficacy of the default risk factor in an emerging market context using the Fama-French five-factor model. Our aim is to test whether the Fama-French five-factor model augmented with a default risk factor improves the predictability of returns of portfolios sorted on the firm's characteristics as well as on industry. The default risk factor is constructed by estimating the probability of default using a hybrid version of dynamic panel probit and artificial neural network (ANN) to proxy default risk. This study also provides evidence on the temporal stability of risk premiums obtained using the Fama-MacBeth approach. Using a sample of 3,806 firm-year observations on non-financial listed companies of Pakistan over 2006-2015 we found that the augmented model performed better when tested across size-investment-default sorted portfolios. The investment factor contains some default-related information, but default risk is independently priced and bears a significantly positive risk premium. The risk premiums are also found temporally stable over the full sample and more recent sample period 2010-2015 as evidence by the Fama-MacBeth regressions. The finding suggests that the default risk factor is not a useless factor and due to mispricing, default risk anomaly prevails in the Pakistani equity market.

  • Pulse wave velocity (PWV) is used to non-invasively estimate the severity of arteriosclerosis by measuring arterial stiffness. Increased arterial stiffness measured by PWV stands for progressive arteriosclerosis and is caused by atherosclerotic risk factors. This study is focused on how brachial-ankle pulse wave velocity (baPWV) is related to the leading risk factors for arteriosclerosis or atherosclerosis. Subjects were 114, 69 males and 45 females who are in 60's and had baPWV test for acute stroke. The results are as follows: the group with increased arterial stiffness showed significant increase in HbA1c, total cholesterol, BSBP (brachial artery systolic blood pressure), BDBP (brachial artery diastolic blood pressure), CSBP (central artery systolic blood pressure), CDBP (central artery diastolic blood pressure), augmentation index (AIx) and diabetes mellitus. Correlation analysis between baPWV and atherosclerotic risk factor showed significant relationship in age, HbA1c, LDL cholesterol, BSBP, BDBP, CSBP, CDBP and augmentation index. baPWV was independently related to age and BSBP in multiple linear regression analysis. The group with increased arterial stiffness was independently related to BDBP in multiple logistic regression analysis. This study might be meaningful in evaluating the relationship between arterial stiffness and atherosclerotic risk factor in a new way, and be helped to make various studies for cardiovascular disease.
