Objectives: This study investigated the relationship between prescribing institutions and medication adherence among patients newly diagnosed with hypertension and diabetes. Methods: This study investigated patients with new prescriptions for hypertension and diabetes in Korea in 2019 with using data collected from general health screenings. A multilevel logistic regression model was applied to explore the relationship between patients' first prescribing institution and their medication adherence, defined as a medication possession ratio (MPR) over 80%. Results: The overall adherence rates were 53.7% and 56.0% among patients with hypertension and diabetes, respectively. The intra-class correlation coefficients were 13.2% for hypertension and 13.8% for diabetes (p<0.001), implying that the first prescribing institution had a significant role in medication adherence. With clinics as the reference group, all other types of hospitals showed an odds ratio (OR) less than 1.00, with the lowest for tertiary hospitals (OR, 0.30 for hypertension; 0.45 for diabetes), and the next lowest in health screening specialized clinics (OR, 0.51 for hypertension; 0.46 for diabetes). Among individual-level variables, female sex, older age, higher insurance premium level, and residing in cities were positively associated with adherence in both the hypertension and diabetes samples. Conclusions: This study showed that the prescribing institution had a significant relationship with medication adherence. When the first prescribing institution was a clinic, newly diagnosed patients were more likely to adhere to their medication. These results highlight the important role played by primary care institutions in managing mild chronic diseases.

Amongst a number of potential nonviral vectors, cationic liposomes have been actively researched, with both gemini surfactants and bola amphiphiles reported as being in possession of good structures in terms of cell viability and in vitro transfection. In this study, a cholesterol-based diquaternary ammonium gemini surfactant (Chol-GS) was synthesized and assessed as a novel nonviral gene vector. Chol-GS was synthesized from cholesterol by way of four reaction steps. The optimal efficiency was found to be at a weight ratio of 1:4 of lipid:DOPE (1,2-dioleoyl-L-${\alpha}$- glycero-3-phosphatidylethanolamine), and at a ratio of between 10:1~15:1 of liposome:DNA. The transfection efficiency was compared with commercial liposomes and with Lipofectamine, 1,2-dimyristyloxypropyl-3-dimethylhydroxyethylammonium bromide (DMRIE-C), and N-[1-(2,3-dioleoyloxy)propyl]-N,N,N-trimethylammonium chloride (DOTAP). The results indicate that the efficiency of Chol-GS is greater than that of all the tested commercial liposomes in COS7 and Huh7 cells, and higher than DOTAP and Lipofectamine in A549 cells. Confirmation of these findings was observed through the use of green fluorescent protein expression. Chol-GS exhibited a moderate level of cytotoxicity, at optimum concentrations for efficient transfection, indicating cell viability. Hence, the newly synthesized Chol-GS liposome has the potential of being an excellent nonviral vector for gene delivery.

Background: Arrhythmia due to QT prolongation is one of the most serious adverse events with drug interactions in the elderly. This study aimed to examine the incidence of arrhythmia in Korean elderly patients who administered both cytochrome P450 3A4 (CYP3A4) substrates and inhibitors. Methods: Patients using CYP3A4 substrate and inhibitor were selected from the 2017 elderly patient dataset (the Korean Health Insurance Review and Assessment Service - Aged Population Sample). Selection criteria were patients with a medication possession ratio over 80%, medication duration of at least 7 days, and a follow-up period of 3 months or more. The patient's basic information is age, gender, health insurance type, and comorbidities. The top 50 drug pairs and comorbidity with high-incidence arrhythmia were presented. Results: In patients with drug combinations for over 7 days, there were 981 incidences of arrhythmia, and 351 incidences in those with combinations for over 30 days. The comorbidities of congestive heart failure and myocardial infarction had a significant association with incidence of arrhythmia. Among patients with 7 days or longer, the drug pairs [substrates-inhibitors] with significant adjusted odds ratio (aOR) were [propranolol-cimetidine] (aOR, 2.25; 95% confidence interval [CI], 1.66-3.04). Among patients with 30 days or longer, the drug pairs with significant aOR were [tramadol-amiodarone] (aOR, 2.87; 95% CI, 1.97-4.19). Conclusions: In elderly patients, the incidence of arrhythmia was high with drug interactions of CYP3A4 substrates and inhibitors. The comorbidity of congestive heart failure was the risk factor.
The Purpose of this study is to find the effect factors of R&D investment in SMEs which plays an important role in the national economy, and the differences of the effect factors by the type of SMEs. The subject of this study is about 3,400 SMEs mentioned in "The survey of technical statistics on SMEs in 2007" by Korea Federation of Small and Medium Business. The effect factors are related with the size of business, the infrastructure of R&D and the activities of R&D which have been studied by many researchers. The methods of analysis are regression analysis, moderating effect analysis and the software package used is SPSS 12.0. The results of the study are as fallow. First, it was found that unlike in previous studies which show the effect of the elements of business's size, research infrastructure, research activities on R&D investment, one element alone can't be considered for meaningful result but the various elements have effect on R&D investment at the same time. In other words, the number of employees and the sales as the elements of business's size, the ratio of researchers, the technical ability, the ratio of equipment possession and the intellectual properties as the elements of R&D infrastructure, the activity of ideas and joint research as the elements of R&D activities have positive(+) effect, whereas the participation of CEO in the activity of R&D as the elements of R&D activities activity has negative(-) one. The number of employees, the ratio of researchers, and the sales had relatively high influence whereas equipment possession, technical ability, intellectual properties, the participation of CEO in the research, the activity of idea, joint research had relatively low influence. Next, it was also found that there are differences of the effect factors over the types of SMEs. SMEs were classified into 19 types by eight criteria such as start-ups and existing business by business age; small business and medium business by size; manufacturing business and service business by product type;independent business and subcontractor business by dealing type; businesses in the entering, growing, maturing and restructuring stage by growth stage; businesses with low, medium and high technology by technological level; pioneering business and non-pioneering business by industrial type; and businesses with state-of-the-art technology and non-advanced business by the level of business activities. The meaning of this study lies in the fact that it found the various effect factors should be considered at the same time when conducting study on SMEs' R&D investment, and the differences by the type should be acknowledged. This study surpassed the limitations of the previous studies which focused on a couple of factors and types. This study result can also be considered for other studies on achievement, organization, marketing and others. Moreover, it shows that a differential policy by business type is needed when formulating SME policy.
Purpose: The purpose of this study was to evaluate the effects of long term osteoporosis management education consist of exercise, drug therapy, and nutrition on bone mineral density (BMD) and medication compliance among postmenopausal women who have just been diagnosed with osteoporosis. Methods: The research design consisted of a pre-and post-test quasi-experimental design through a nonequivalent control group. The participants in this study were 60 individuals with osteoporosis, and who were classified according to two groups; the control group (n=30) who were given general clinical guidelines, and the experimental group (n=30) who received management education once for 60 minutes every three months using a standardized educational sheet. After one year, BMD was assessed using band dual energy X-ray absorptiometry (DXA) and medication possession ratio (MPR) for medication compliance. Analysis of collected data was performed using descriptive statistics t-test, chi-test, and paired t-test. Results: No significant difference in BMD (t=-1.02, p=.311) and MPR (t=-0.77, p=.440) was observed between the two groups. However, a significant increase in femur neck BMD was observed in the experimental group compared with the control group (t=-2.18, p=.033). Conclusion: Conduct of further study will be needed for examination of the effect of long-term osteoporosis management education on BMD Level and Medication Compliance in Postmenopausal Women.

The construction of the equipment of water utilization has been developed since the ancient Korea period, 1906 in order to develope and modernize the agriculture. As the results, 83% of total paddy field area, 1,268,949.8 ha has developed into the irrigated paddy field, and the rest of area, 17% has remained nonirrigated paddy field (due to the data of the statistics of 1975). The ratio of the irrigated paddy field area among the total weir was marked 13.14% (area, 137,926.3 ha) and the third grade of total irrigated paddy field in accordance with the facilities of water utilization. In case of Gangwon-Do, the 44.18 percentage of the total irrigated paddy field, 51,057.2ha has been and pointed out first grade. As the results, we found out the following articles : 1. The total weir, 1,641 that sumed concrete weir 647 and conventional weir 967 has been constructed and has irrigated the 44.l8% of total irrigated paddy field of Gangwon-Do. 2. These weirs have been public possession of those villages to be 96.1 percentage of total weir and was controled by them. 3. Those weirs that were constructed across tributary (first, secondary and third tributary) at vallies (elevation 100∼1,000m) have marked that 45 percentage of total number of catchment area has 100∼1,000 ha, and 70 percentage of total number of basin area has been below 10 ha and has constructed about 5 of step-shape. 4. The construction of most weirs has became generally about 50m length, about 1m height. 5. The 80 percentage of newly constructed concrete weir has aged below 10 years. It seemed that 79 percentage of conventional weir has aged over 20 years and 41% of contructed weir has needed to be improved quickly. 6. If privious weirs, 296 will constructed newly, they can irrigate 3,600.8 ha of paddy field and 45.8% of total irrigated paddy field will have been and will contribute to the production of much rice.
Objectives : This study aims to estimate the oral antihyperglycemic medications adherence among ambulatory care with adult type 2 diabetes patients and to identify factors affecting the medication adherence in Korea. Methods : This study used the Korean National Health Insurance Database. Study population was 40,082 patients who were 20 years of age or older and first diagnosed with type 2 diabetes (ICD-10: E11) in 2004. The patients were followed up for two years in order to measure adherence with oral antihyperglycemic medications. The level of medication adherence was measured by the medication possession ratio (MPR). Results : The average MPR in the study population was 49.5%. The appropriate adherence rate (MPR$\geq$80%) was 29.4% and showed variation according to the characteristics of individual patients. Multiple logistic regression analysis revealed that the odds of appropriate adherence increased with female (OR:1.21, CI:1.14-1.27), older age, increasing ambulatory care visits, health insurance (OR:1.53, CI:1.33-1.76), decreasing ambulatory care providers, using a specialized general hospital as their main attending medical institution (OR:10.08, CI:8.96-11.33), having co-morbidity, using polytherapy (OR:1.07, CI:1.01-1.13). Conclusions : The medications adherence for patient with type 2 diabetes is low in Korea, and shows variation according to the characteristics of patients. For proper management of diabetes, health care policy is expected to be enacted to improve medications adherence continuously. In particular, more intensive management is needed for patients with low medications adherence. Also, health care policy makers need to develop the program to induce health care utilization by a patient to be more concentrated with the same provider.
