Nitrate is taken up from the soil by plants for protein synthesis and present in vegetables as a natural component and/or contaminant. The objective of this study was to estimate nitrate(NO3-) contents of some vegetables(Chinese cabbage, radish, lettuce, spinach) which were produced in Korea and to provide a scientific basis for the evaluation of risk to public health arising from dietary exposure to nitrate. A total of 400 samples were analysed for nitrate contents using our ion chromatography. From the results, in general, nitrate levels in vegetables produced by 2 harvest seasons were not different. The minimum, maximum and mean values of nitrate were 311, 5522 and 2788 for spinach; 542, 4484 and 2287 for lettuce; 273, 4151 and 1551 for radish; 362, 3015 and 1498(mg/kg) for Chinese cabbage. Nitrate contents of vegetables grown in Korea were similar to those of vegetables grown in other countries.

Low-level laser therapy (LLLT) is the application of light to pathology to promote tissue regeneration, reduce inflammation, and relieve pain. LLLT has a photochemical effect whereby the light is absorbed and exerts a chemical change. The clinical applications of LLLT include improvement in wound and bone healing processes, control of pain and tooth hypersensitivity, modulation of periodontal inflammation, the prevention and treatment of cancer therapy-induced oral mucositis, management of burning mouth syndrome, and improvement in temporomandibular disorder symptoms. Further research is needed to better elucidate the cellular mechanisms of LLLT and provide a solid scientific basis for the clinical application of LLLT in dentistry.

Purpose: The purpose of the study was to explore the meaning of conflicts in nurses caring DNR (do-not-resuscitate) patients. Methods: The participants were 7 nurses caring DNR patients. Data were gathered using in-depth interviews. The interviews were recorded and transcribed verbatim. Colaizzi method was used to analyze the data. Results: The significant results can be categorized into 7 concept descriptions and 5 theme clusters by analyzing the interviews. The major theme clusters for the experiences of nurses were 'Pity about exceptional nursing actions', 'Pity about the unilateral decision making', 'Pity about halfhearted family love', 'Pity about unprepared circumstance for deathbed', and 'Pity about the absent guideline for DNR'. Conclusion: The finding of this study will help nurses resolve conflicts in caring DNR patients and provide a scientific basis for developing nursing intervention strategies for DNR patients.

This study is a thesis about the hair art reflected minimalism which is expanded to various art fields using minimum formative measures minimalism is a kind of modern art trend. It is analyzed theoretically that the works of this researcher approaching minimalism and consideration of minimalism about hair, flexible clothes and artistic costume. It is defined that the "hair art" is "aesthetic hair", and I include my three works approaching minimalism that are researched, extended, made. I spread the works which have minimalism characteristic by design intent, concept, title, color, ingredient, size and detail, consider the hair art works theoretically and present the basis and method of scholar study minimalism art trend. I think that succeeding studies related to the hair art should be continued. I expect that various work activities of hair art artists and scientific breakthrough via theoretical thesis about the work of themselves.

The paper reports a wide overview of the scientific activities on Structural Health Monitoring (SHM) in Italy. They are classified on three different conceptual scales: national territory (macro); regional area (medium); single structure (small). In the latter case differences have been pointed out between permanent installation and short-term experimental campaigns. A particular focus has been dedicated to applications devoted to cultural heritage which have an important historic, strategic and economic value for Italy. Two specific cases, the first related to the permanent monitoring of an historical Basilica and the second regarding the dynamic testing of a modern structure, have been presented as a basis for a general discussion.

Recently, interest in detoxification therapies is increasing. Coffee enema has been most frequently used as one of detoxification therapies. However, there is lack of scientific basis for coffee enema, regarding its clinical efficacy and safety respectively. This study aimed to produce the general features of coffee enema such as definition, protocols, clinical applications and efficacies, and side effects. Total 37 articles coffee enema were collected from 7 databases including PubMed, and reviewed thoroughly. The majority of papers were review studies or case reports for effects/side-effects of coffee enema. The quality of papers was generally poor, and no randomized controlled clinical trial (RCT) was exist. This study shows the current status of coffee enema-related study, and suggests the demand for RCT study to develop the evidence-based detoxification therapy using coffee enema.

This report is devoted to the problems of Mongolian Railway Transportation Safety such as high length of wagon service life, defects due to the more factors of exploitation, idle time, increase of faults, poor condition of repairing shops and more hand and mechanical operations and these conditions are quite difficult to meet the safety and reliability of increasing transportation from day to day. The paper discusses that the most optimum solution is diagnosing before occurring wear, breakdown, and defects on the basis of studying characteristics of structural material breakdown, residual methods of voltage, effects of material hardness and linear defects of a crystal net and the reform of machines is very important to implement it. It focuses the structures, characteristics of the material transportation and tests and analyses of the wagon cart which has to meet the traffic safety of wagons and slow and soft movement. The study is done on the wagon chassis which has to meet the traffic safety of luggage wagons.

Probiotics are traditionally defined as viable microorganisms that have a beneficial effect in the prevention and treatment of pathologic conditions when they are ingested. Although there is a relatively large volume of literature that supports the use of probiotics to prevent or treat intestinal disorders, the scientific basis behind probiotic use has only recently been established, and clinical studies on this topic are just beginning to get published. Currently, the best studied probiotics are lactic acid bacteria, particularly Lactobacillus and Bifidobacterium species. Other organisms used as probiotics in humans include Escherichia coli, Streptococcus sp., Enterococcus sp., Bacteroides sp., Bacillus sp., Propionibacterium sp., and various fungi, and some probiotic preparations contain more than one bacterial strain. Probiotic use for the prevention and treatment of antibiotic-associated diarrhea caused by Clostridium difficile induced intestinal disease as well as for other gastrointestinal disorders has been discussed in this review.

Three-dimensional rigid plastic FEM is adopted to analyze the extruding-bulging process of tee tubes. Equivalent strain-rate stress distributions and the deformation characteristic in extruding-bulging process of tee tubes are revealed which provide scientific and reliable basis for correctly designing technologcial scheme and rationally selecting parameters. meanwhile some approaches for three-dimensional rigid plastic FEM are also discussed in this paper

Although the scientific evidence is not entirely supportive, atypical antipsychotics have been used widely for the treatment of children and adolescents with mental illnesses as alternatives to typical antipsychotics which have more serious unwanted adverse effects than atypical neuroleptics. On the basis of clinical experiences and research data, atypical antipsychotics have been prescribed for adolescents with schizophrenia, manic or mixed episodes of bipolar disorders, tic disorders, aberrant behaviors in pervasive developmental disorders, and impulsive or violent behaviors in disruptive behavior disorders. Due to their efficacy and relatively more tolerable side effects, the use of atypical antipsychotics has become increasingly popular in child and adolescent psychiatry. However, we should pay attention to the limitations associated with short-term clinical experiences and the lack of well-designed controlled studies, especially in terms of adverse effects including those involving metabolic processes.
