  • Purpose: This study aimed to conduct a qualitative synthesis of workplace bullying experiences among nurses in Republic of Korea. Methods: Following the PRISMA guideline, a literature search was conducted using seven domestic and three international databases. Studies published in Korean or English from inception to December 31, 2022 were included. A meta-aggregation approach suggested by the Joanna Briggs Institute was used to synthesize the research findings. Results: Fourteen studies were included in this review. As a result of a data analysis of the selected studies, 199 subthemes and supporting illustrations were identified and grouped into 36 related categories. Based on the subthemes and categories, five synthesized findings were developed: (1) the individual and organizational causes of workplace bullying; (2) the various types of physical violence and psychological harassment; (3) the negative impact of workplace bullying and its effect on self-growth; (4) active and passive coping efforts in dealing with bullying; and (5) strategies for preventing bullying incidents. Conclusion: Based on the synthesized findings, four recommendations were made: (1) improving the challenging working conditions for nurses; (2) enhancing educational programs for new nursing graduates; and (3) promoting proactive responses from nursing managers in conjunction with an expansion of resilience training for nursing students. Finally, to address the issue of workplace bullying, (4) multi-center and multi-level research involving nursing organizations needs to be conducted.

  • N-Benzoylglycylanilide and N-benzoylalanylanilide derivatives were synthesized from N-benzoylglycine and N-benzoylalane with anilines. respectively. The products were identified by elemental analysis, IR, UV and NMR spectra with N-benzoylglycylanilide (I), N-benzoylglycyl-o-toluidide(II), N-benzoylglycyl-m-toluidide(III), N-benzoylglycyl-p-toluidide(IV), N-benzoyl-L-alanylanilide(V), N-bnzoyl-L-alanyl-o-toluidide(VI), N-benzoyl-L-alnnyl-m-toluidise(VII), N-benzoyl-L-alanyl-p-toluidide(VIII). These compounds were tested for their phytotoxicity to the germination and seedling growth of rice, radish, green pea plants and turf grass. Among them, N-benzoyl-Lalanyl-m-toluidide had strongly inhibitory effect on the seedling growth of radish seeds, and N-benzoyl-L-alanylanilide showed an inhibitory activity especially upon the seedling growth of turf seeds. In addition, the inhibitory rate of plant seed growth differed with the isomeric position(ortho, meta and para) of methyl group; N-benzoylglycyl-m-toluidide was more effective than both N-benzoylglycyl-o-toluidide and N-benzoylglycyl-p-toluidide derivatives, and also N-benzoyl-L-alanyl-m-toluidide was more effective than both N-benzoyl-L-alanyl-o-toluidide and N-benzoyl-L-alanyl-p-toluidide.

  • A synthesis and the screening of new 2-iminothiazolines (IV) of which structures are modified based on a lead compound, thiazoline for development of new agrochemical fungicide were described. Bromination of acetoacetanilides (I) which were prepared by the reaction of diketene with anilines gave the corresponding ${\gamma}-bromoacetoactanilide\;(II)$. Treatment of II with N-phenyl-N'-methyl thiourea (III) afforded IV, structure of which was confirmed by various spectroscopic methods. Antifungal activity of the new IV was tested against six kinds of typical plant diseases (in vivo). The IV with aromatic substituents showed remarkable activity against the Pyricuraria oryzae at 250 ppm in primary screening. The candidates with control value over 90% in primary screening were selected and further tested for second screening at lower concentrations. The IV which has an electron-withdrawing substituent such as halogen, especially fluorine in aryl group showed a higher activity as compared to those with electron-donating group and meta substituent was for optimal position.

  • Intact cells of Acinetobacter sp. T5-7 completely degraded trichloroethylene (TCE) following growth with phenol. This strain could grow on at least eleven aromatic compounds, e.g., benzaldehyde, benzene, benzoate, benzylalochol, catechol, caffeic acid, 2.4-D, p-hydroxybenzoate, phenol, protocatechuate and salicylate, and did grow on alkane, such as octane. But except phenol, other aromatic compounds did not induced TCE degradation. Phenol biotransformation products, catechol was identified in the culture media. However, catechol-induced cells did not degrade TCE. So we assumed that phenol hydroxylase was responsible for the degradation of TCE. The isolate T5-7 showed growth in MM2 medium containing sodium lactate and catechol rather than phenol, but did not display phenol hydroxyalse activity, suggesting induction of enzyme synthesis by phenol. Phenol hydroxylase activity was independent of added NADH and flavin adenine dinucleotide but was dependent on NADPH addition. Degradation of phenol produced catechols which are then cleaved by meta-fission. We identified catechol-2.3-dioxygenase by active staining of polyacrylamide gel.

  • Epidemiology and preventive medicine are changing together with Population and health and with ever expanding medical and non medical technologies. New technologies make epidemiology methodologically more sophisticated, but such advances risk overshadowing epidemiology's most important role: raising questions, providing answers, and helping the medical decision-making at ail levels of prevention. Epidemiology also plays a major role in the evaluation of new and other technologies whose effectiveness is poorly known. Epidemiological approaches, methods, techniques, and interpretations are widely used in new and rapidly expanding fields of medicine: research evaluation and synthesis (meta-analysis), establishment of guidelines for clinical preventive practices, new medical technology assessment, guidelines for national and international health policies, evidence-based medicine, outcomes research and disease management ('population-based' medicine and quality of care improvement). In the nearest future, infectious and noninfectious diseases may cease to be almost the sole subjects of epidemiology and they may share their place with other mass phenomena of the next millennium, such as medical practices and care, or political, social and economic actions and their consequences. Not only will primary, secondary, and tertiary Prevention will remain in the epidemiological mainstream, but health protection and health promotion will require perhaps a redefinition of epidemiology in these domains. Epidemiology and preventive medicine are both subjects of medical ethics and dilemma for right choices.

  • Objectives: The purpose of this study is to identify the effectiveness of fumigation treatment, provide a clinical basis for fumigation therapy, and develop treatment protocols through consideration of treatment methods and herbal medicines. Methods: We searched for randomized controlled clinical trials using fumigation treatment on mycotic vaginitis in 8 electronic databases such as EMBASE, Pubmed, and CNKI. The results of the studies were analyzed and the risk of bias was assessed by using Cochrane risk of bias tool. A meta-analysis was performed to reveal the effectiveness of fumigation compared to control treatments. Results: We finally selected 5 studies among 54 articles according to inclusion criteria and exclusion criteria. In all selected studies, herbal fumigation was more effective than any control treatment and all the studies were statistically significant. Conclusions: The study provides a basis for applying fumigation treatment to patients with mycotic vaginitis and helps developing a treatment protocol of caring patients of mycotic vaginitis. But the limitation of this study is that the number of studies included is small and quantitative synthesis of all results has not been achieved.

  • Separation/recovery of valuable metals such as zinc, nickel or tin from copper alloy dross has recently attracted from the viewpoints of environmental protection and resource recycling. In this study, preliminary investigation on separation of tin (Sn) from copper alloy dross using selective dissolution method was performed. The tin in the copper alloy dross did not dissolve in an aqueous nitric acid solution which could allow the concentration/separation of tin from the copper alloy dross. Precipitation of tin as $H_2SnO_3$ (meta stannic acid)occurred in the solution and transformed to tin dioxide ($SnO_2$) after drying process. The dried sample was heat-treated at low temperature and its crystal structure, surface morphology and chemical composition were investigated.

  • ${\alpha},{\beta}$-Unsaturated carboxanilides 5 with trifluromethylated dihydro-1,4-oxathiins were synthesized for the development of new agrochemical fungicide. Chlorination of trifluoromethylated ${\beta}-keto$ ester 6 followed by the reaction with 1,2-mercaptoethanol gave intermediate 1,4-oxathiane 11. Without purification of 11, substitution of hydroxy group by chlorine, followed by dehydrochlorination of 10 in the presence of triethylamine afforded trifluoromethylated dihydro-1,4-oxathiin ethyl ester 9. Acylation of the hydroxy group of the carboxylic acid 12 followed by treatment of various amines gave the corresponding trifluoromethylated dihydro-1,4-oxathiin carboxamides 5. Antifungal screening (in vivo) of the synthesized compounds against typical plant diseases, which include rice blast, rice sheath blight, cucumber gray mold, tomato late blight, wheat leaf rust, and barley powdery mildew, was carried out. Where meta position of the phenyl group was substituted with isopropoxy or isopropyl group, excellent antifungal activities against rice sheath blight and wheat leaf rust were detected.

  • The purpose of this systematic review was to investigate the association between periodontal disease and chronic kidney disease. A search of Embase, PubMed and The Cochrane Library databases was performed up to April 17, 2016. Article selection was based on cohort study design and the study subjects were patients with periodontal disease or severe periodontal disease. The final result was development of chronic kidney disease and kidney function decrease based on the estimated glomerular filtration rate values. The quantitative synthesis of the final selected articles was assessed using Review Manager statistical analysis software. A fixed-effects model meta-analysis was performed to estimate the degree of association between periodontal disease and chronic kidney disease. The search strategy identified 3,018 potentially eligible articles, of these, four studies were finally selected for meta-analysis, revealing that periodontal disease was significantly associated with the risk of developing chronic kidney disease (odds ratio, 1.65; 95% confidence interval, 1.44~1.90; p<0.001). In order to prevent the development of chronic kidney disease and kidney function decrease it is important to prevent periodontal disease, as well as minimizing the traditional risk factors known to reduce the quality of life of patients and increase disease burden.

  • [ ${\alpha},{\beta}$ ]-Unsaturated carboxamides 12 with trifluromethylated dihydro-1,4-dithiins were synthesized for the purpose of development of new agrochemical fungicide. Chlorination of trifluoromethylated ${\beta}$-ketoester 4 followed by tile reaction with 1,2-ethanedithiol gave intermediate 1,4-dithiane 9. Without purification of 9 substitution of hydroxy by chlorine followed by dehydrochlorination in the presence of triethylamine afforded trifluoromethylated dihydro-1,4-dithiin ethyl ester 7. Activation of the hydroxy of the carboxylic acid 10 obtained from the hydrolysis of 7 and then reacted with various amines gave the corresponding trifluoromethylated dihydro-1,4-dithiin carboxamides. Antifungal screening (in vivo) against typical plant diseases, Rice Blast, Rice Sheath Blight, Cucumber Gray Mold, Tomato Late Blight, Wheat Leaf Rust, and Barley Powdery Mildew of the synthesized compounds was carried out. As a result, most of the compounds shlowed weak antifungal activities and some compounds in which isopropyl group was substituted in meta of the phenyl showed antifungal activity (99%) at 250 ppm against the disease Wheat Leaf Rust.
