본 연구는 우리나라의 고등학생들이 SNS를 사용시 중요시하는 요인이 무엇인지를 알아보기 위하여 사회적 동기, 기능적 동기, 유희적 동기, 심리적 동기가 SNS 이용만족도에 어떠한 영향을 주며 이러한 만족도는 가치관에 어떠한 영향을 주는지를 알아보고자 하였다. 그 결과 사회적 동기를 제외한 유희적 동기, 기능적 동기, 심리적 동기가 SNS 이용만족도에 어떠한 영향을 주며 이러한 만족도는 학생들의 가치관 형성에 긍정적인 영향을 주는 것으로 나타났다. 이러한 결과는 우리나라의 고교생들이 SNS를 사용하는 이유는 자신들이 필요로 하고 자신들이 즐거워하는 즉 개인적인 관점에서 SNS를 사용하는 것이지 사회적 현상 등과는 관계가 없다라고 할 수 있다. 하지만 사회적 동기는 기능적 동기, 유희적 동기에 긍정적인 영향을 주는 것으로 나타났다. 즉 사회적 동기인 여러가지 사회적 현상은 청소년들이 SNS를 사용하는 계기 및 주제를 제공한다고 할 수 있으며 기능적 동기는 유희적 동기와 심리적 동기에 긍정적인 영향을 주는 것으로 나타났다. 즉 SNS가 제공하는 여러 다양한 기능이 SNS를 선택하여 사용하는데 긍정적인 작용을 한다는 결과를 도출하였다.

Purpose - This research is to review the state of standard labeling compliance and identify the factors that are conducive to compliance with the Labeling Standards of the Health Functional Foods Act in internet distribution. Research design, data, and methodology - We checked 9 labels including product name, expiration date, manufacturing date, raw material, ingredient, operative dose, nutritional information, daily intake, and functional effect which are based on Labeling Standards of the Act from 100 health functional foods in the internet shopping malls. These 9 structure & function claims were compared using a Chi-square test. Results - There was a statistically significant difference in the use of standard labeling between domestic product and imported products (p<.001). The related strength between these two variables showed a moderate effect size. Also, there was a statistically significant difference between accredited advertising/unaccredited advertising distinction and use of standard labeling (p<.001). The related strength between these two variables showed a moderate effect size. Conclusions - The Labeling Standards of the Act were not followed and found to be related to imports or unauthorized advertising in internet distribution. The information displayed according to the Labeling Standards was only about 2 on the average, so many labels have been posted unreadably without arrangement.

Objectives: This study examines the effect of Sagunja-tang on functional dyspepsia (FD) through a systematic review and meta-analysis of a randomized controlled trial (RCT). Methods: A search for RCTs that tested the effect of Sagunja-tang on functional dyspepsia was conducted in Medline, Embase, PubMed, CENTRAL, CiNii, CNKI, NDSL, RISS, OASIS, and KISS databases on November 8, 2020, with no limit on the year of publication. A meta-analysis was performed by synthesizing the findings, including total efficiency, clinical symptom score, myosin light-chain kinase (MLCK) level (pg/mL, and gastric half-emptying time (min). RevMan 5.4.1 software was used for data analysis. The quality of the literature was evaluated using Cochrane's risk of bias (RoB) tool. Results: A total of 14 RCTs met the selection criteria. As a result of the meta-analysis, the treatment group had higher total efficacy and MLCK levels (gastric antrum, jejunum) than the control group, and the clinical symptom score and gastric half-emptying time were lower. However, due to the low quality of the included RCT and the small sample size, the results may be slightly biased.

In this study, we report a novel encapsulation method for longevity of an organic thin-film transistor (OTFT) using pentaceneby means of an adhesive multiplayerincluded Al film. For encapsulation of OTFTs, the Al film adhered onto the OTFT in a dry nitrogen atmosphere using a proper adhesive. A lifetime, which was defined as the time necessary to reduce mobility to 2% of initial mobility value, was observed from the typical $I_{D-VD}$ characteristics of the field-effect transistor (FET). The initial field effect mobility ${\mu}$ was measured to be $2.0{\times}10^{-1}\;cm^2/Vs$. The characterization was maintained for long times in air. No substantial degeneration occurred. The performance and the stability are probably due to the encapsulation effect.

We investigated the anti-obesity effect of berberine in mice fed a high fat diet and focused on the analysis of adipogenesis in epdidymal adipose tissue. Male C57BL/6J mice were divided into three groups, which were fed either a normal diet (Nor), a high fat diet (HFD), or a high fat diet plus orally administered berberine (0.2 g /kg body weight) (HFD+B) for 8 weeks. Relative to mice in the HFD group, mice in the HFD+B group showed significant reductions in weight gain and adipose tissue weight. Serum triglyceride levels in mice from the HFD+B group were significantly lower than those of the HFD mice, as were the levels of serum insulin and leptin. An effect of berberine to reduce epididymal adipose mass was revealed by H&E staining. Berberine inhibited the high fat diet-induced increase in levels of the proteins CD36 and CCAAT/enhancer-binding protein $\alpha$ ($C/EBP{\alpha}$) observed in epididymal adipose tissues of mice from the HFD group. These results suggest that berberine has an anti-obesity effect in mice and that the effect is mediated by inhibition of adipogenesis.

During monocarpic senescence in higher plants, functional stay-green delays leaf yellowing, maintaining photosynthetic competence, whereas nonfunctional stay-green retains leaf greenness without sustaining photosynthetic activity. Thus, functional stay-green is considered a beneficial trait that can increase grain yield in cereal crops. A stay-green japonica rice 'SNU-SG1' had a good seed-setting rate and grain yield, indicating the presence of a functional stay-green genotype. SNU-SG1 was crossed with two regular cultivars to determine the inheritance mode and identify major QTLs conferring stay-green in SNU-SG1. For QTL analysis, linkage maps with 100 and 116 DNA marker loci were constructed using selective genotyping with $F_2$ and RIL (recombinant inbred line) populations, respectively. Molecular marker-based QTL analyses with both populations revealed that the functional stay-green phenotype of SNU-SG1 is regulated by several major QTLs accounting for a large portion of the genetic variation. Three main-effect QTLs located on chromosomes 7 and 9 were detected in both populations and a number of epistatic-effect QTLs were also found. The amount of variation explained by several digenic interactions was larger than that explained by main-effect QTLs. Two main-effect QTLs on chromosome 9 can be considered the target loci that most influence the functional stay-green in SNU-SG1. The functional stay-green QTLs may help develop low-input high-yielding rice cultivars by QTL-marker-assisted breeding with SNU-SG1.

This study, adopting the pretest-post test experimental study, is designed to find out how the functional electrical stimulation makes effect on the balance of a patient with spasticity of the ankle plantarflexor muscle caused by hemiplegic after stroke. The 46 subjects for this study were randomly sampled out of the patients who were hospitalized from September 1, 2003 to November 30, 2003 in H sanitarium in Yangpyung. The patients were with spasticity of the ankle plantarflexor muscle caused by hemiplegic after stroke and able to walk without supporting implements. The purpose of the study is firstly to analyze the change of ROM, FRTof a patient with spasticity of the ankle plantarflexor muscle when the functional electrical stimulation is applied and secondly to find out how the sex, age, height, weight, part of the diagnosis, duration of pain, experience of relapse and getting hurt from a fall of a patient make effect on the change. The experimental group for the study is divided into two to compare the differences of the effect. The exercising treatment only was performed for the conrtol group, and the functional electrical stimulation to the ankle dorsiflexor muscle as well as the exercising treatment was applied to the experimental group. The ROM test was performed to check the range of motion of the ankle with a double armed universal goniometer. The test was done 3 times to take an average. FRT were performed to check the balance. The statistical test was conducted using the SPSS 10.0/PC program by means of the following methods: χ2-test and t-test for testing homogeneity between the groups; paired t-test, independent sample t-test, F-test, and two-way ANOVA for analyzing the changes before and after the treatment. The levels of statistical significance of all the data were maintained at p<.05. According to the test, ROM has more decreased in experimental group than in control group when the functional electrical stimulation was applied only to the experimental group. However, the significant statistic difference was not shown (p=.059). FRT showed remarkable differences in the experimental group compared to the control group, showing the significant statistic difference (p=.000). On the one hand, the change of ROM, FRT related with the sex, age, height, weight, part of the diagnosis, and experience relapse was a meaningless minimum value. The change of ROM related to the duration of pain and the experience of falling down was also meaningless. However, FRT showed significant statistic difference (p<.05). According to the test above, the application of functional electrical stimulation to a patient with spasticity of the ankle dorsiflexor muscle caused by hemiplegic after stroke makes significant effect on the balance of a patient, but the result has nothing with the sex, age, height, weight, part of the diagnosis, duration of pain, experience of relapse and getting hurt from a fall of a patient. However, it is regarded to give contribution to the balance improvement of a patient. Therefore, this study expects to be a valuable clinical material for a patient with spasticity.

Objective: Functional dyspepsia is a prevalent disease. It impedes subjective quality of life. The purpose of this study was to examine the equivalent effect of herb medicine treatment (DA-9701) for functional dyspepsia. Methods: In this randomized, single-blinded, placebo-controlled study, we compared a herb medicine (DA-9701) with standard treatment (mosapride) and placebo for the treatment of functional dyspepsia. 42 volunteers who satisfied the requirements were enrolled in study. Severity of dyspepsia was measured by Nepean Dyspepsia Index (NDI) and Functional Dyspepsia Quality of Life (FD-QOL) before and after treatments. Results: 1. In the DA-9701 group, total key symptoms score was significantly lower and improve rate of key symptoms was higher than in the mosapride and placebo groups, but there were no statistically significant differences between three groups. 2. In the DA-9701 and mosapride groups, "nausea" and "bad breath" were significantly lower compared with the placebo group. 3. In the DA-9701 group, NDI Quality of Life scores were significantly higher, but there were no [other] statistically significant differences between the three groups. 4. In the DA-9701 and mosapride groups, FD-QOL scores were higher compared with the placebo group, but there were no statistically significant differences between the three groups. Conclusion: Herb medicine treatment (DA-9701) is effective to improve the symptoms and quality of life in patients with functional dyspepsia.

Background: Functional massage is a therapeutic massage that incorporates joint motion in non-end-range to reduce pain and improve range of motion (ROM) in patients. This study was aimed at investigating the immediate effect of functional massage on pain, range of motion, balance ability and, gait speed of patients having undergone total hip replacement. Methods: Twenty patients were treated by one participating orthopedic manual physical therapist and randomly assigned to the control group (n=10) or the experimental group (n=10). To treat patients of each group, functional massage and range of motion exercises were used. The experimental group received a functional massage and the control group received range of motion exercise for minutes for one session. The visual analog scale was used for pain assessment. Balance ability was measured using a timed up and go test and a one-leg standing test for patients. The 10-meter walk test was used for the measurement of gait speed assessment of patients. Results: Significant improvements were observed in terms of balance ability (p<.05), gait speed (p<.05), and ROM (p<.05) after functional massage. There was no significant inter-group difference (p>.05). Conclusion: Application of the functional massage showed that statistically significant improvements in ROM, gait speed, and balance ability after a single treatment session. This technique may be a useful treatment in patients having undergone total hip replacement.
