Purpose: The purpose of this study was to investigate the effectiveness of an educational intervention that used both cellular phones and the Internet to provide a short messaging service (SMS) relating to blood glucose, blood pressure, and serum lipid levels in postmenopausal women with impaired fasting glucose (IFG). Methods: Twenty-eight postmenopausal women were assigned to an intervention group and twenty-one postmenopausal women to a control group. The intervention was provided for 12 weeks. Patients in the intervention group were asked to access a web site by using a cellular phone or to use the Internet directly and input their blood glucose and blood pressure levels weekly. Participants were sent the optimal recommendations weekly by both cellular phone and Internet. Results: The intervention group had a mean decrease in systolic blood pressure (SBP) level of 8.1 mmHg but changes for the control group were not significant. There was a significant mean change in diastolic blood pressure (DBP) level for the intervention group (-7.7 mmHg). The mean change in the control group was not significant. Conclusion: This educational intervention using the Internet and a SMS by cellular phone improved levels of SBP and DBP in postmenopausal women with IFG.

The purpose of this study was to analyze and evaluate dietary intake between with and without hypertension. Study subjects were more than 30 years old adults (n = 3,806) who participated in the 2001 Korea National Health and Nutrition Examination Survey. People who have 'self-recognition about hypertension' and 'having diet for hypertension' were excluded. Using the WHO standard, subjects were divided into the hypertensive group (SBP> 140, DBP> 90) and the normal group (SBP< 140, DBP< 90). The Body Mass Index (BMI) and the Waist-Hip Ratio (WHR) of a hypertensive group were higher than those of a normal group (p < 0.01). The distribution of the subjects for smoking, alcohol consumption, exercise, stress, preference of salty food were not significantly different between a normal group and a hypertensive group (p>0.05). Dietary intakes were investigated by the 24-hour recall method. When food and dish intakes analyzed by sociodemographic factors, normal group consumed more fruits than those of a hypertensive group. Statistical significant were shown at female group, residences in metropolitan area and having elementary school education (p<0.05). Hypertensive group consumed more alcoholic beverages than those of a normal group at 'age 39-39', 'aged 50-64', 'high economic status', 'low economic status' and 'residences in metropolitan' (p<0.05) The amount of intakes for fat, potassium, thiamin, vitamin C and alcohol were significantly different between the normal group and the hypertensive group (p<0.05). The highest score of the Dietary diversity score (DDS) was 4 in both normal group and hypertensive group. Normal group showed high Nutrition Density (ND) of vitamin C and hypertensive group showed high ND of sodium. In summary, these results showed that significant difference for people with hypertension were intakes of fruits, alcohol, thiamin, vitamin C. And these results differed by sociodemographic groups. Therefore, the differential approach in each group is demanded for prevention and control of the hypertension.

In this study, we prepared PVDF membranes via TIPS for water treatment applications. PVDF was used for its excellent chemical and mechanical properties. The effect of coagulation bath composition, temperature, and heat capacity on the overall membrane morphology was studied and observed using SEM. A mixture of DOP and DBP was used as the diluent, and silica was used as an additive. It was observed that as the heat capacity of the coagulation bath increased, the crystallization rate of PVDF decreased yielding larger pores. Also, as the heat capacity of the coagulation bath decreased, the crystallization rate of PVDF increased yielding smaller pores.

The most common 8 phthalic acid esters (PAEs) and adipate in sediment were measured 5 times from 1999 to 2001 at 11 sites of river in Korea. Ultrasonication extraction with dichloromethane was done for extraction of the sediment. After concentration GC/MS-SIM analysis was performed. Three compounds (DEP, DBP and DEHP) among eight phthalic acid esters were detected from the sediment samples, and the other PAEs were not detected in any samples. DEHP (27.3~63.6%) was detected with higher frequency than any other compounds for sediment samples. And this compound had shown the highest average concentration (81.7~427.6 ng/g).

This study was performed to survey the school supplies such as pencil, eraser, notebook and color paper. Twenty-two kinds of samples were collected near the school zone, and eight kinds of phthalate which is one of the environmental hazard factors analyzed to estimate the contents characteristics of products. As the results of these research, three kinds of phthalates (BBP, DNOP and DIDP) were not detected in the selected samples. In the A group, DEHP and DINP were detected in the rage of 22%~28%, and DINP was selected 28%, 24% and 28% in the A-1, A-3 and A-4 samples, respectively. But the selected samples in the B group were detected less than 1,000 ppm as regulated level. Also, The DBP was detected 1% in the C-2 sample, and DEHP was detected 0.3% in the C-1 and C-6 samples. The DEHA was detected 0.3% in the D-3 sample. In this study, the DINP was mainly detected the eraser, therefore this kind of phthalate can be exposed through dermal exposure.

In this study, we used thermally induced phase separation (TIPS) to produce water treatment membrane and poly(vinylidene fluoride) (PVDF), silica with excellent mechanical properties and chemical resistance to evaluate characterization of the membrane. The diluents used for the characterization were dioctyl phthalate (DOP) and dibutyl phthalate (DBP). We observed the crystallization temperature, cloud point and SEM images to see the manufacture conditions according to the ratio of PVDF and silica. The crystallization temperature and cloud point increased with the contents of silica. Through the phase diagram drawn from these results, the conditions for the preparation of the membrane confirmed.

Ginseng is one of the most-widely used herbal remedies. This systematic review evaluates the current evidence for its use in the reducing blood pressure (BP) in patients with hypertension. Systematic searches of 12 electronic databases were conducted without language restrictions. All randomized clinical trials (RCTs) of ginseng as a treatment for hypertension were candidates for inclusion. Methodological quality was assessed using the Cochrane risk of bias. Five RCTs met the inclusion criteria. The risk of bias was low in most of the trials. Four of the included RCTs compared the effectiveness of ginseng to placebo. The meta-analysis of these data failed to show a statistically significant acute effect on systolic BP (SBP) or diastolic BP (DBP). However, subgroup analyses showed beneficial effects of Korean red ginseng (KRG) on both SBP (n=54, mean difference [MD], -6.52; 95% confidence interval [CI], -9.99 to -3.04; p=0.0002) and DBP (n=54, MD, -5.21; 95% CI, -7.90 to -2.51; p=0.0001). Two RCTs tested the long-term effects of ginseng for BP for 24hours. One of these trials failed to show any benefits of KRG compared to no treatment, and the other failed to show superior effects of North American ginseng compared to placebo. Adverse events with ginseng were none in one trial or not assessed. Collectively, these RCTs provide limited evidence for the acute effectiveness of KRG in the treatment of high BP. The total number of RCTs included in the analysis and the total sample size were insufficient to draw definitive conclusions. More rigorous studies are warranted.

Formation of disinfection by-products (DBPs) including trihalomethans (THM), haloacetic acid (HAA) and haloacetonitriles (HAN) from chlorination of extracellular organic matter (EOM) and cells + intracellular organic matter (IOM) of Microcystis sp., a blue-green algae, during decomposed period was investigated. Microcystis sp. cells + IOM and EOM of Microcystis sp. exhibited a high potential for DBP formation. HAAFP (formation potential) was higher than THMFP during decomposed period. In the variations of HAAFP species during decomposed period, the ratio of di-HAAFP species was gradually decreased and the ratio of tri-HAAFP species was gradually increased in the case of EOM during decomposed period, while the opposite result was in the case of cells + IOM during decomposed period. In the variations of HANFP species during decomposed period, the ratio of di-HANFP species was much higher than the ratio of tri-HAAFP species.

Purpose: This study was done to present guidelines for deciding appropriate times for measuring blood pressure (BP) in patients with neurological disorders who had surgery due to brain damage. Method: It was a repeated measures-experimental research on time variants in BP after nursing care. SBP (Systolic BP) and DBP (Diastolic) were measured every 2 minutes up to 5 times using an EKG patient monitor. Measured data were analyzed using repeated measures ANOVA and paired t-test. Results: For suctioning, there were significantly higher differences for SBP averages after 2 min. (138mmHg, p<0.01) and 4 min. (133mmHg, p<0.01) compared to before suctioning (120mmHg). For position change, there were significant differences in SBP averages after 2 min. (136mmHg, p<0.01) and 4 min. (130mmHg, p=0.01) compared to before changing position (121mmHg). For position change followed by suctioning there were significant differences in SBP averages after 2 min. (136mmHg, p<0.01), 4 min. (136mmHg, p<0.01) and 6 min. (125mmHg, p=0.003) compared to before the interventions (121mmHg). Conclusions: Results indicate that there are significant differences in SBP and DBP over time during nursing interventions, suggesting clinical measurement of BP after 6 min. or 8 min. be done for patients with neurological disorders in neurosurgery clinics.
