Purpose: The purpose of this study was to analyze the current status of studies related to the learning methods of biological nursing subjects in Korea. Methods: Five databases (KoreaMed, KMbase, NDSL, KISS, KiSTi) and grey literature were searched prior to February 2018. A total 12 studies met the inclusion criteria including 11 articles and 1 proceeding. Results: We included five experimental studies, five non-experimental studies, and two mixed method studies. First, most of the studies that applied a learning method focused on the subject of human anatomy and physiology; team-based learning was the method that was utilized the most. Second, the necessity of well-designed research was confirmed because the quality of included studies was low. Third, the research variables identified were mainly concentrated on the affective domain, and included satisfaction, motivation, self-efficacy, self-directed learning, confidence, attitude. We confirmed the need to develop a learning program that can also improve the cognitive and psychomotor domain variables in future research. Conclusion: The results of this study suggest that further research should be conducted with consideration the domain of research variables evenly. In addition, future studies should apply various learning methods and included randomized controlled trials.

Purpose: The purpose of this study was to evaluate the effectiveness of spiritual intervention studies by examining biological, psychological, and spiritual outcomes. Methods: From electronic databases 2522 studies were retrieved, of which 21 studies met the inclusion criteria. These studies had 1411 participants. Two authors independently extracted data from the selected studies and assessed the methodological quality. The data were analyzed using the RevMan 5.1 program of the Cochrane library. Results: Overall effect size of spiritual intervention on spiritual and psychological (depression and anxiety) outcomes were moderate (d= -0.65 to d= -0.76, p<.001). The effects on biological outcomes (pain and functional status) ranged from -0.51 to -0.39, respectively. No publication bias was detected as evaluated by a funnel plot. Spiritual intervention had a moderate effect on psychological and spiritual outcomes and a smaller effect on biological outcomes. Conclusion: The results of this study suggest that spiritual intervention can relieve depression and anxiety. Further randomized controlled trials studies are needed to evaluate the effects of spiritual intervention on biological outcomes.

Purpose: The purpose of this review was to identify the current status of nursing studies on heart failure (HF) patients in South Korea and to suggest future study direction. Methods: A literature review of databases such as KoreaMed, KERIS and nursing and allied health journal were searched with key terms 'heart failure' and 'nursing' for the period from January 2000 to February 2017. A total of 35 studies including 28 articles and 7 theses met the inclusion criteria. Results: Twenty-seven out of 35 studies were observational studies on outpatients and most of the studies did not mention the ejection fraction and New York Heart Association functional classification class (NYHA class) in the inclusion criteria. Self-care and health-related quality of life as psychological factors, and physical activity as a biological factor, were used as main variables. However, we found it difficult to understand how much score indicates better quality of life because of an inconsistent and wide score. In quality assessment, 8 intervention studies had no serious flaws. Conclusion: Further studies should consider more biological and social factors influencing HF. The quality assessment with respect to nursing intervention studies in HF showed that randomized and double-blind trials are needed.

Most suicides(about 90%) occur in the context of psychiatric disorders. Prediction of suicide risk in patients with mental illness is very important in preventing suicide attempts. However, current approaches to predict suicidality are based on clinical history and have low specificity and biological markers are not yet included. Many studies have explored the association between different biological parameters and suicidality. Studies of cerebro-spinal fluid(CSF) demonstrated that 5-HIAA and HVA levels were lower in patients with a history of suicide. Platelet serotonin transporter and the 5-HT2 serotonin receptor have also been studied in relation to violence and suicide. Depressive patients with greater suicidal tendency had significantly lower cholesterol concentrations but some researchers failed to find the correlation. DST non-supression is reported to predict suicidality in major depression. Several studies demonstrated a relationship between intron 7 polymorphism of tryptophan hydroxylase and suicidal behavior. Since suicide is not occurred in a single disease, the systematic and comprehensive study in large samples with various diagnoses is necessary to find the biological and genetic predictors of suicidal behavior.

The Kentish Plover (Charadrius alexandrinus ; family Charadriidae; genus Charadrius) is a small bird that moves from continent to continent depending on the season. On the Kentish Plovers, phylogenetic studies have been widely conducted to classify different species or subspecies and to determine the time of speciation. However, the perspectives on the interspecific or intraspecific relationships in the phylogenetic analysis of Kentish Plovers remain debatable. Here, we reviewed the differences between the Kentish and Snowy Plovers (C. nivosus ) in terms of their morphology, ecology, and genetic information. Particularly, their differences in genetic information can be well demonstrated; however, the intraspecies differences in the populations that live in different environments can relatively be poorly explained. We suggest that not only genetic features but also morphological, ecological, and behavioral traits are important when comparing the Kentish Plovers with other species, such as the Snowy Plovers, in phylogenetic studies. Furthermore, we suggest that phylogenetic studies on the subspecies of the Kentish and Snowy Plovers should be conducted for their better identification.

Metabolomics is the study of global metabolite profiles in a system (cell, tissue, or organism) under a given set of conditions. Metabolomics has its roots in early metabolite profiling studies but is now a rapidly expanding area of scientific research in its own right. In this study, the applications of metabolomics in natural product studies are explored. Ginseng is a well-known herbal medicine and has various pharmacological effects, which include antiaging, anticancer, antifatigue, memory enhancing, immunomodulatory, and stress reducing effects. Metabolomic analysis of organic acids has not been performed for evaluation whether ginseng has been cultivated using conventional or environmental-friendly farming methods. In this study, profiling analysis was conducted for organic acids (OAs) in ginseng roots produced using conventional or environmentfriendly farming methods at five locations in each of five regions. In OA profiles, lactic acid was the most abundant OA in all regions, with the exception for environmentally friendly farmed ginseng in two of the five regions, in which glycolic acid was most abundant OA. OA profiles in all regions showed isocitric acid levels were increased by environment-friendly cultivation, which suggests metabolic differences associated from farming method, and that isocitric acid might be a useful discriminatory biomarker of environmental-friendly and conventional cultivation. The results of the present study suggest metabolomic studies of OAs in ginseng roots might be useful for monitoring whether ginseng has been cultivated using conventional or environmentally friendly farming methods.

Korean ginseng has been thought and used the most very important medicinal herb among the oriental medicinal drugs for thounds of years Korean ginseng had many ingredients such as tripenoid saponins. Nitrogen compounds, polysaccharides, polyacetylenic compounds and lipid compounds. Korean ginseng has wide effects in the various systems of human such as nervous system. Vascular system. Digestive system. endocrine system, immune system. etc. Many researchess who were interested in the biological effects of Korean ginseng have concerned the tripenoid saponins among the components of ginseng and carried out to find the effects of ginseng using the various experimental system. From their results, it was unveiled many effects of Korean ginseng gractually in the experimental systems and shown that Korean ginseng has various effects in the biological system. But recent studies has been carried out to the difference ginseng components, besides ginseng saponin thought to have various effects in biological systems. Also the functional mechanism of ginseng in the biological system is limited but the basic research to elucidate the mysterious effects of ginseng has been preferred. In this review, we focus on biological effects of Korean ginseng. Especially physiological and biochemical aspects in biological systems.

We have described the synthesis and biological activity of novel retinamide . The retinamide derivatives were synthesized by introducing functional side chains into the 4-hydroxy group of 4-HPR. The activities could be dependent on the side chain length, functional group, and hetero atom. The antiprolife-rative potential of the derivatives was assessed by MTT assay in HCT116 cancer cell lines.
