Background: Glycemic control is an effective way to reduce the cardiovascular complications of diabetes, but more than half of the adults with diabetes in Korea are improperly controlling their glycemic levels. The purpose of this study is to identify the factors associated with poor glycemic control in type 2 diabetes patients. Methods: This study analyzed 1,261 subjects ${\geq}30years$ old diagnosed with type 2 diabetes who participated in the fifth Korean National Health and Nutrition Examination Survey (2010-2012). Poor glycemic control rates were defined as hemoglobin A1c (HbA1c) level ${\geq}7%$. To shed light on the causes of poor glycemic control, socio-demographics, diabetes severity, health status, and health behavior factors were adjusted and logistic regression was done. Results: Of the total 1,261 patients, 53.0% of patients with type 2 diabetes had HbA1c ${\geq}7%$. After running a logistic regression model, the odds ratio of poor glycemic control was higher in high school graduates than elementary school graduates; in people living in Chungcheong and Jeolla/Jeju than those living in Seoul; in the group with diabetes for over 5 years had diabetes less than 5 years; in a group with insulin and oral hypoglycemic agent treatment than non-treatment; in a group with hypertriglyceridemia than without hypertriglyceridemia; and in the group with slept less than 6 hours slept 7-8 hours. Conclusion: We need a comprehensive public health policy to reduce the poor glycemic control rates in type 2 diabetes patients. We should recognize the education levels, duration of diabetes, diabetes treatment, hypertriglyceridemia, and sleep duration were associated with poor glycemic control.

This study sought to evaluate the mechanism of cellular injury caused by ferrous sulfate (FeSO₄) and the protective effects of Parnassia palustris L. (PP) extract against FeSO₄-induced cytotoxicity of cultured C6 glioma cells. FeSO₄ is known to cause neurotoxicity and induce Parkinson's disease. The antioxidative effects of PP, such as superoxide dismutase (SOD)-like and superoxide anion-radical (SAR)-scavenging activities, as well as effects on cell viability, were studied. FeSO₄ significantly decreased cell viability in a dose-dependent manner and the XTT₅₀ value, the concentration of FeSO₄ which reduced the cell viability by half, was measured at 63.3 μM in these cultures. FeSO₄ was estimated to be highly cytotoxic by the Borenfreund and Puerner toxicity criteria. Quercetin, an antioxidant, significantly improved cell viability, damaged by FeSO₄-induced cytotoxicity. While evaluating the protective effects of the PP extract on FeSO₄-induced cytotoxicity, it was observed that the extract significantly increased cell viability compared to the FeSO₄-treated group. Also, the PP extract showed superoxide dismutase (SOD)-like and superoxide anion radical (SAR)-scavenging activities. Based on these findings, it can be concluded that FeSO₄ induced oxidative stress-related cytotoxicity, and the PP extract effectively protected against this cytotoxicity via its antioxidative effects. In conclusion, natural antioxidant sources such as PP may be agents useful for preventing oxidative stress-related cytotoxicity induced by heavy metal compounds such as the FeSO₄, a known Parkinsonism inducer.

This study was aimed to provide the basic data for the development of effective educational program by reflecting the opinions of the visiting health service workers. The subjects were 144 visiting health service workers in Gwangju and Jeollanam-do area who responded the mail questionnaire. The data were collected from June to July, 2001 using questionnaire composed of the education need, knowledge by subjective appraisal, and experience of education. The major findings of this study were as follows: 1. The number of respondents who received at least one education within recent three years were 43(29.9%) at the central level, 57(39.6%) at the provincial level and 53(36.8%) at the district level. The satisfaction with education was higher at the central level than at the provincial and district level. 2. Knowledges by subjective appraisal on the 'chronic degenerative diseases management' and 'health promotion' was relatively high. while that of 'rehabilitation' was low. 3. The knowledge by subjective appraisal of visiting health service was related with experience of education and license status. The knowledge was higher in registered nurses than in nurse aids. The curricula related to increased level of knowledge of visting health service workers were 'elderly health care', 'rehabilitation' and 'psychiatric-mental health nursing' educations at the central level 'continuing education for the community health practioners' and 'psychiatric-mental health education' at the provincial level and 'elderly health care', 'rehabilitation' 'psychiatric-mental health' and 'acute diseases control' educations at the district level. 4. The respondents preferred elderly health management as the contents of education, officer group education as the method of education, province(30.4%) as the main body of education, exercise and practice as the form of education, 2-3 times per year as the frequency of education, and 3-5days as the period of education. The findings of this study could suggest that future education program should be planned to increae the knowledge level of visiting health service workers by reflecting their educational need.
