A lignan and four flavonoid derivatives were isolated from the aerial parts of Panicum dichotomiflorum Michaux (Gramineae) through repeated column chromatography. Their chemical structures were identified as (-)-pinoresinol (1), tricin (2), luteolin (3), luteolin-4´-O-β-D-glucopyranosde (4) and luteolin-7-O-β-D-glucopyranosde (5), respectively, by spectroscopic analysis. These compounds were isolated for the first time from this plant.

Ten phenolic compounds were isolated from the twigs of Stewartia pseudocamellia. The isolated compounds were identified as 5,7,3',5'-tetrahydroxyflavanone (1), 3,5,7,3',5'-pentahydroxyflavanone (2), quercetin (3), (+)-aromadendrin (4), (+)-ampelopsin (5), myricetin (6), (+)-catechin (7), (-)-epicatechin (8), kaempferol (9), and fraxin (10) by spectroscopic analysis. Compounds 1, 2, 4, 6, 8, and 9 were isolated from this plant for the first time. The antioxidant activities of compounds 1-10 were evaluated by the DPPH and/or ORAC (oxygen radical absorbance capacity) assay. Compounds 3, 5-9 showed significant antioxidative effects on DPPH assay. Among the active compounds, 6 exhibited higher activity compared to trolox on ORAC assay.

Purpose: This study analyzed the research published in KCI-registered journals related to healthcare marketing for the last 27 years from 1995 to 2022 to identify academic research trends, the specificity of the healthcare field and to suggest future research directions. Methodology: A total of 213 articles were selected for this study, and a descriptive analysis of the period and journals was conducted, as well as the analysis of research topics and keywords from the perspective of marketing strategy factors and performance factors. Findings: A total of 213 articles related to healthcare marketing have been published in the last 27 years. The descriptive analysis showed a steady quantitative increase, but the STP field showed a decreasing trend, and many papers were mainly published in the Korean Journal of Hospital Management. According to the analysis of research topics and keywords, STP field will be hard to become an active research topic in the future, and even in the 7P field, only Product, People, and Process can be researched according to medical law regulations, and other factors such as PX & WOM, CRM, and the Internet fields are expected to be research topics. Implications: Through the analysis of research trends over the past 27 years, we were able to identify the specificity of the healthcare marketing field in Korea and suggest future research directions based on this.

Purpose: The purpose of this study is to develop a model that predic ttshe prevalence of chronic diseases, such as hypertension, diabetes, stroke, myocardial infarction, angina, arthritis, and osteoporosis, using height, weight, waist circumference, and grip strength, whcih can be easily measured in the field wit h counseling. Method: In the 2019 National Health and Nutrition Survey raw data w aasnalyzed using multistage strat-i fied cluster sampling. Doctors’ confirmation of chronic disease was set as the dependent variable, with independent variables including gender, age, height, weight, grip strength, and waist circumference. Results: High blood pressure increased with age and waist circumference. In stroke, as the average grip strength increased, the incidence rate decreased. Additionally, as age increased and maximum grip strength improved, the incidence rate also increased. For myocardial inafrction, the rate was 2.57 times higher in men than in women in terms of gender factors, and for arthritis, it was higher in women than in men, with age and lower maximum grip strength. For osteoporosis, women had a higher incidence rate than men, and the higher the average grip strength, the lower the incidence rate. Diabetes was found to have a higher incidence rate as the waist circumference increased and was not related to any other factors. Conclusion: Therefore, simple and reliable measurement in the field is highly likely to be used as a major tool to predict chronic diseases.
Mechanism design and dynamic analysis of a multi-functional endoscopic clipping device
배종진,양승한,강남철 대한기계학회 2013 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.27 No.3
Minimal invasive surgery using endoscopic clipping devices is widely used in the treatment of hemorrhages and perforations in the gastro-intestinal tract. Although endoscopic clipping devices have been used for over 30 years and have undergone continuous development, there is still a need to improve their functions. In response to this, new mechanisms for multi-functional endoscopic clipping devices have been developed in this study. Dynamic simulation is performed to analyze the mechanical behavior of the developed clipping device. Optimization of the clip spring location to maximize clipping forces is also achieved by finite element analysis.
