As healthcare systems demand that nurses be competent in using electronicmedical records for patient care, the integration of electronic medical records into nursing curricula has become necessary. The purpose of this study was to explore how students, new nurses, clinical instructors, and faculty perceive the integration of academic electronic medical records into the undergraduate clinical practicum. From January to February 2014, four focus group interviews with 18 participants were conducted based on purposive sampling. Content analysis was used on the unabridged transcripts to extract themes and develop meaningful categories. Three major themes and eight subthemes were revealed from the focus group interviews. The major themes were "electronic medical record as a learning tool for clinical practicum," "essential functions of academic electronic medical records," and "expected outcomes of academic electronic medical record." Participants expected academic electronic medical records to enhance students' nursing informatics competencies. The findings of this study can inform the process of developing academic electronic medical records for clinical practicum, which will then augment students' informatics competencies. © 2016 Wolters Kluwer Health, Inc.

The GNSS positioning is widely used in the performance of forest tasks because of its convenience. Recently, mobile device could be used in positioning according to the development of smartphone technology. But the result of GNSS positioning without precise GPS involves large positioning errors. In case of forest area, these positioning errors increase more because tree canopies or topographies interfere with receiving the GNSS satellite signals. In this study, GNSS positioning experiment in the forest area with hand-held GNSS and smart phone were performed. As a result, accuracy analysis of these devices and usability of smartphone GPS for GIS data acquisition were presented. © Research India Publications.

Banaba (Lagerstroemia speciosa Pers) leaves has been used as tea or decoction type in the Philippines for blood sugar control and used in the treatment of diabetes in India and contain a treterpenoid compound know as a corosolic acid which can promote the absorption and utilization of glucose in the cell by transporting the stimulated glucose. As such, banaba plays a role in regulating levels of blood sugar and insulin in the blood. Banaba might decrease blood sugar but most of countries prefer to use diabetes medications even though they aware of serious side-effects. Additionally, various adverse effects are reported recently when many diabetic patients have been taken antidiabetic drugs in the long term. Here we reviewed whether banaba and corosolic acid can be replaced for current antidiabetic drugs through published several mechanisms of banaba and antidiabetic drugs, respectively. Consequently, banaba, one of medicinal herbs for antidiabetic effect surely can be functioned and can be a perfect candidate instead of antidiabetic drugs on lowering or maintaining normal blood sugar levels and prevention of diabetic complications without as well as treatment without any adverse effects.

This study was to evaluate the influence of hemp addition and extrusion conditions on properties of dough and bread. The extruded and non-extruded hemp/ rice flours with different hemp/rice ratio were mixed with wheat flour at 15% ratio. In those flour assays, extrusion greatly decreased the paste viscosities, while the addition of hemp inhibited the decrease of peak viscosity on the extrusion condition. The onset gelatinization temperature was extended due to the hemp addition. The test on dough properties showed that extrusion increased water absorption, arrival time, weakness, extensibility, and the volume after 105 min fermentation, and decreased the stability time and elasticity of dough, while hemp addition mainly increased the weakness and extensibility. For bread properties, extrusion decreased the specific volume, crust and crumb L value, and uniformed air cells, when the hemp addition increased the bread specific volume and decreased the hardness during storage time. © 2013 The Korean Society of Food Science and Technology and Springer Science+Business Media Dordrecht.

The effects of acidic polysaccharides purified from Gastrodia rhizome on blood pressure and serum lipid levels in spontaneously hypertensive rats (SHR) fed a high-fat diet were investigated. Acidic polysaccharides were purified from crude polysaccharides by DEAE-Sepharose CL-6B. Thirty-six male SHR were randomly divided into three groups: Gastrodia rhizome crude polysaccharide (A), acidic polysaccharide (B) groups, and a control group (C). A 5-week oral administration of all treatment groups was performed daily in 3- to 8-week-old SHRs with a dose of 6 mg/kg of body weight/day. After 5 weeks of treatment, total cholesterol in the acidic polysaccharide group, at 69.7 ± 10.6 mg/dL, was lower than in the crude polysaccharide group (75.0 ± 6.0 mg/dL) and the control group (89.2 ± 7.4 mg/dL). In addition, triglyceride and low-density lipoprotein cholesterol levels in the acidic polysaccharide group were lower than in the crude polysaccharide and control groups. The atherogenic index of the acidic polysaccharide group was 46.3% lower than in the control group. Initial blood pressure after the initial three weeks on the high-fat diet averaged 195.9 ± 3.3 mmHg among all rats. Compared with the initial blood pressure, the final blood pressure in the control group was increased by 22.8 mmHg, whereas it decreased in the acidic polysaccharide group by 14.9 mmHg. These results indicate that acidic polysaccharides from Gastrodia rhizome reduce hypertension and improve serum lipid levels. © 2012 by the authors; licensee MDPI, Basel, Switzerland.

Diabetes mellitus is a condition in which a person has a high blood sugar/glucose level. This is because the body does not produce enough insulin, or because the body cells do not properly respond to the insulin that is produced. Herbal treatment for diabetes has been a part of traditional medicine for thousands of years. The natural herbs for diabetes treatment focus on lowering blood sugar, reducing the damaging effects of the disease and maintaining of a safe, healthy level of blood glucose. Many diabetic patients seeking an alternative treatment to traditional drugs turn to natural herbs for help. This review article provides very useful information of officially-approved antidiabetic natural ingredients [Table 1] by KFDA, thereby providing consumers with a wise decision when they purchase the effective nutraceuticals for diabetes. Therefore, medicinal herbs may be used to prevent and treat diabetes reliably and safely when the government approves the ingredients or products officially.

Objectives: Human papillomavirus (HPV) is a major cause of cervical cancer, which is the second most common cancer in women. HPV E6 initiates degradation of cellular tumor suppressor protein p53, induces human telomerase reverse transcriptase (hTERT) activity, and then leads to progressive cervical carcinogenesis. Methods: In this study, the CervicGen HPV RT-qDX assay (Optipharm, Osong, Republic of Korea), which detects 16 HPV high-risk subtypes (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, and 69), and the CervicGen hTERT RT-qDX assay (Optipharm) were evaluated using 545 ThinPrep (Hologic, Bedford, MA) Papanicolaou samples. Results: The positivity for the HPV E6/E7 messenger RNA (mRNA) assay was 94.4%, 95.2%, 82.4%, 46.5%, 25.0%, and 1.1% in squamous cell carcinomas, high-grade squamous intraepithelial lesions (HSILs), atypical squamous cells - cannot exclude HSIL, low-grade squamous intraepithelial lesions, atypical squamous cells of undetermined significance, and normal cytology samples, respectively. Five cervical intraepithelial neoplasia grade 2+ samples were not detected by the HPV E6/E7 mRNA assay, but they exhibited positive signals in the hTERT mRNA assay. Notably, the hTERT mRNA expression level was increased in high-grade cervical lesions but was very low in all 288 normal samples. Conclusions: These data suggest that the combination of HPV E6/E7 and hTERT mRNA expression levels could be used in a complementary manner in diagnosing high-grade cervical lesions and malignant tumors and might be useful as a predictive marker in monitoring low-grade cervical lesions. © American Society for Clinical Pathology.

Many salts have the ability to attract and remove water vapor from the surrounding environment. The ability of each salt to remove water vapor is based on the flow rate and temperature of air in surrounding. The objective of this study was to investigate the humid control characteristics in air-water system by using a desiccants. The aim is to asses the influence of three parameters on the humid control process which are air volume rate, air temperature and desiccant amount. Humidity control materials which consist of K (potassium) or Na (sodium) have been synthesized by the aqueous process. The humidity control properties of materials have been also investigated. Experiment results are as following. Thermal characteristics of desiccants showed similar properties regardless of processing condition. The experiments were examined by using artificial air-water system (humidity: 70̃93%, air volume rate: 0.22̃0.69 m 3 /s). The results showed that the Na-type desiccant was an effective material. It was found that dew point increased with air volume rate, and the humidity change in humid control process was depended on desiccants amount.
