  • Peanut seeds are characterized by high oils and proteins with good quality, and are utilized as an edible oil source and a protein-rich food products. The end products, being peanut butter, salted seed, confections, roasting stock and other by-products are favored in world-wide because of their unique roasted peanut flavor. As with many other foods, interest in the composition and chemistry of peanut is largely a result of thier use as human food. Thus, a more complete knowledge of thier chemical and food quality and flavor properties is desired. Literatures are reviewed mainly focucing on the physicochemical properties and nutritional quality of oil, protein and flavor in peanuts. Chemical properties of protein and oil, and volatile flavor component in peanut seeds are studied extensively in view point of chemical and food nutritional value. But in crop base, the synthesis and genetic studies of the chemicals could not provide valuable informations on the breeding for quality improvement. Some essential amino acids are limiting in peanut seeds and the tocopherols are very important in oil stability and for dietary adequacy ratio in high linoleic acid peanut oil, but it is thought to be quite difficult to improve by breeding technique as their lack information of gene actions. However, the selections of high protein and oil, and some essential amino acids and linoleic acid rich genotypes could be helpful for the quality improving. Research studies are also needed to elucidate the relationships between flavor components and consumer perception of peanut flavor.

  • The idea that parental involvement has a positive influence on gifted children is so intuitively appearing that society in general. and educators in particular, have considered parental involvement as the remedy for many problems in education. However the vast proportion of the literatures in this area give results qualitatively. Among the empirical studies that have investigated this issue quantitatively, there appear to be considerable inconsistencies. A meta-analysis was conducted to synthesize the quantitative literatures about the relationship between parental involvement and gifted development. The findings reveal a moderate relationship between parental involvement and gifted development. We focused on the effect between parental involvement and gifted development, and conducted meta-analysis involving correlation coefficients between the two constructs. Using correlation coefficients, We can get the effect size, and explain the influence. We initially identified 539 articles over twelve-year period. Based on abstracts of these 539 articles, 463 studies were used for analyzing the current stream of the study. Finally, 15 studies met our inclusion criteria, and were subsequently used in this meta-analysis. From the 15 studies, 37 variables influenced on gifted development were collected. Using meta-analysis, it is revealed that internal effects for gifted development have stronger relationship than parents' socioeconomic status. In addition, the differences between female and male student have been reducing.

  • Drugs mostly represent an efficacy or an adverse effect according to their dosage and/or plasma concentrations. Therefore, to investigate the pharmacokinetic behavior of drugs including herbal medicines is necessary both to maximize the drug action and to minimize the adverse effect. To date, pharmacokinetic studies of herbal medicines have been conducted by some experts in this field on the bases of science and knowledge in Korea. On the other hand, in advanced countries, a typical series of pharmacokinetic studies has been conducted by using a harmonized guidance established. Consequently, an administrative support on these studies has to be needed in Korea as well. This study aimed to establish a draft guidance on pharmacokinetic studies of herbal medicines in non-clinical and clinical studies. Literatures previously published as well as guidances in the US, Europe and Japan were summarized for the present guidance. Effect of herbal medicines was listed on the proteins in charge of drug metabolism and transportation, as well as on the pharmacokinetics of chemical drugs. The present suggestion might be helpful to proceed pharmacokinetic studies of herbal medicines efficiently, and further polish should be needed in terms of an administrative point of view.

  • The purpose of this study is to systematically review and to objectively identify the effect size in order to understand the effects of horticultural therapy on cognitive function, depression, self-esteem, and activity daily living(ADL) of dementia patients. Related studies published in Korean and English were selected by searching domestic and foreign academic databases. The risk of bias assessment of individual studies was performed on the included 18 literatures. Horticultural therapy was found to be significantly effective in cognitive function(effect size=1.06), depression(effect size=0.64), self-esteem(effect size=0.99), and ADL(effect size=1.98) in dementia care. It is expected that related experimental studies will be repeatedly conducted to produce a more objective effect size calculation.

  • Objectives The purpose of this study is to provide clinical evidence of herbal medicine treatment for cerebral palsy by reviewing randomized controlled trials conducted in China. Methods We searched literatures dated up to 17 May, 2017 in China National Knowledge Infrastructure (CNKI), and evaluated methodological quality of those studies using 'Risk of Bias' tool. Results Sixteen studies were selected for analysis. These studies indicated that the total effective rate, motor function, self-care, muscle spasticity were significantly improved in the herbal medicine treatment group, as compared to the control group. The most-commonly-used herbs were Poria (茯?), Astragali Radix (黃?), Glycyrrhizae Radix (甘草), and Atractylodis Rhizoma Alba (白朮). There were no serious adverse events found that were associated with herbal medicine treatment. The methodological quality of included studies was generally unclear or low. Conclusions This study shows that the herbal medicine treatment can be effective and safe in treating cerebral palsy. Further well-designed clinical trials with high methodological quality and appropriate assessment tools need to be performed to solidify these findings.

  • Objectives The purpose of this study is to analyze randomized clinical trials (RCTs) on traditional Chinese medicine to summarize its efficacy and safety for the treatment of functional gastrointestinal disorders (FGIDs) in children. Methods We searched literatures published up to March 19, 2021 using two Chinese electronic databases. Data regarding patients, interventions, results, and adverse events were extracted from RCTs of herbal medicine for children with FGIDs. Results A total of 34 RCTs were included: 16 trials on functional dyspepsia, 7 trials on functional constipation, 6 trials on functional abdominal pain, 4 trials on irritable bowel syndrome, and 1 trial on functional diarrhea. 26 of 29 trials that reported total effective rate, the treatment group showed a significant improvement compared to the control group. Most of other evaluation indicators, such as symptom score, symptom disappearance time, and recurrence rate also demonstrated statistically significant improvement. Of the 16 studies which reported safety, 5 studies reported no adverse reactions in either group, and 4 studies reported no statistically significant differences in the incidence of adverse events between two groups. Also, reported adverse events were mostly mild. Conclusions Herbal medicine may help improve symptoms of FGIDs in children. However, due to limited types of studies on sub-diseases of FGIDs and small sample sizes in each study, additional large scale clinical studies on various other FGIDs are necessary.

  • In this paper, I suggest methodological ways of studying comparative literature regarding ongoing discussions of world and national literature. The role of comparative literature studies has widened in the contemporary era, in which nations have become rapidly entangled and the concept of the world as a unified entity is under question. In this regard, I critically review the traditional principles of the hospitality of cosmopolitanism and the exclusivity of the borders of national literatures. Further, I suggest that scholars adopt the concept by Sigmund Freud of "unfamiliar familiarity" as a methodological motive for studies of comparative literature. Based on this concept, scholars can further develop the unique methods of the discipline of comparative literary studies for teaching and research amidst the ongoing phenomenon of globalization. They can also use these methods to simultaneously contribute to solving the problem of "comparison without a unifying category of the world," as revealed by the results of deconstructional and postcolonial studies. Regarding community-based discussions of literature, I introduce the "bridge and door" metaphor, put forth by Georg Simmel, as a key concept in methodological consideration of translation and in comparative literary studies. In this paper, adopting the metaphor of the bridge and door as an intertextual and social model for comparative studies, I define the new role of comparative literary studies in literary transnationalism, which is particularly necessary when different languages and cultures overlap and become entangled. Regarding the rapidly changing contemporary world community, comparative literary studies, as an experimental discipline, is uniquely capable of examining this kind of community, which forms itself beyond and beneath individual nations.

  • Objectives We aimed to examine health-related economic analysis of available interventions on idiopathic short stature (ISS). Methods Eight studies were reviewed from English, Korean, and Chinese databases which were published up to December 24, 2020. Effectiveness, utility, and cost data were extracted from the studies and descriptive analysis of the individual studies was conducted Results Five studies were chosen. In the two economic evaluation studies, the incremental cost-effectiveness ratio (ICER) of growth hormone (GH) treatment was presented by performing cost-effectiveness analysis based on the deterministic decision tree approach for the GH and untreated group. Final adult height and direct medical costs were analyzed as effectiveness and cost outcomes. In 1 review article, an ICER of GH was presented based on systematic review on the effects of the GH treatment. In the two clinical trials, the effectiveness and cost of the 12 months Oriental medicine combination treatment were presented in comparison with the GH treatment alone. There were no literatures that provided utility data of available intervention on ISS. Conclusions The results of this study will be used as basic data for the economic analysis of Oriental medicine treatment on ISS in the future.
