  • Fume extracting welding gun is one of the promising options for reducing the welder's fume exposure. The performance of the gun was assessed on the basis of capture efficiency. Capture efficiencies were measured in a test chamber recommended by American Welding Society. The overall capture efficiency was turned out to be above 95%. But it did not include the effect of crossdraft existing in the real work environment because all experiments were conducted in a closed chamber. It thus needs more work in the future. In addition, the future directions for improving the pres ent commercial techniques of the gun were discussed.

  • In myocardial perfusion scintigraphy, the results of this evalution now confront the practitioner of nuclear medicing with methodologic options. Most nuclear cardiologic studies are performed using thallium-201, Tc-99m sestamibi and Tc-99m tetrofosmin. Some part of these studies use some form of pharmacologic stress test. While tailoring each test to the individual is ideal, this may be impractical for a busy department. Accordingly, established protocols to be used for patients with similar clinical presentations will be helpful. The following review presents methodology of various imaging protocols mainly according to the guidelines of nuclear cardiology procedures in American Society of Nuclear Cardiology.

  • The purpose of this study was to identify U.S. consumers' preferences for Bibimbap and to determine whether or not Bibimbap can be adopted into the American palate. A total of 214 people tasted a controlled amount of Bibimbap and Gochujang sauce (red chili pepper sauce) and then completed a preference test. Bibimbap was highly rated overall in the areas of appearance, color, smell, and taste. Gochujang sauce was also well-accepted in terms of taste and spiciness. Most of the participants disliked the seaweed and shiitake mushrooms, which means that Bibimbap can improve its garnish taste and aroma by removing them. Further, a more watery sauce was served as foreigners are not familiar with mixing food culture. Therefore, by offering diverse ingredient options, the acceptance of traditional Bibimbap can be increased in the U.S.

  • This scoping review aimed to identify and categorize the available measurement options for vaginal laxity (VL), their indications of use, and whether these measurements can sufficiently provide objective clinical judgment for cases indicated for vaginal rejuvenation with many treatment options nowadays. Systematic searches were conducted on five electronic databases, manually searching articles' bibliographies and predetermined key journals with no date or study design limitations. We included all studies involving VL in their inclusion criteria, treatment indications, and outcome parameters. We used the Arksey and O'Malley frameworks as the guideline in writing this scoping review. Of the 9,464 articles identified, 66 articles and 11,258 subjects were included in the final analysis. The majority of studies were conducted in obstetrics and gynecology (73%), followed by plastic surgery (10%), medical rehabilitation (4.5%), dermatology (4.5%), and others (8%). Most studies originated from the North American region (30%). The following measurement tools were used: (1) interviews, (2) questionnaires, (3) physical/digital examinations, (4) perineometers, and (5) others. Our results suggested that subjective perception of laxity confirmed by directed interview or questionnaire is sufficient to confirm VL. Additional evaluation of pelvic floor muscle through digital examination or perineometer or other preferred tools and evaluation of sexual function through validated questionnaire (Female Sexual Function Index, Female Sexual Distress Scale-Revised, etc.) should follow to ensure holistic care to patients. Future research on the psychometric properties (reliability and validity) of commonly used measurements and the correlation in between subjective and objective measurements should be initiated before their clinical applications.

  • Introduction: Breast cancer is the most common malignancy of women in Kashmir. This study was conducted with the objective of assessing hormone receptor positivity and its correlation with age at diagnosis, tumor size, histological grade and lymph node metastasis. Materials and Methods: 132 newly diagnosed cases of invasive breast cancer diagnosed at the Department of Pathology, SKIMS, Srinagar, J&K, were included after excluding biopsies, in-situ lesions and recurrence cases. Results: Mean age of the patients was 48.2 years, 59.1% being ${\leq}50$ years of age. Mean duration of symptoms was 6.32 months. Most lesions (65.1%) were 2-5 cm and 16.7% were ${\geq}5.0$ cm in greatest dimension. The predominant (80.3%) morphology was IDC-NOS. The majority of the cases presented as grade II (52.1%) lesions and lymph node involvement was present in 65.2%. ER and PR were positive in 66.3% and 63.4% cases, respectively, increasing with rising age. High grade lesions and larger size tumors were more likely to be ER and PR negative. No correlation was found between ER/PR status and lymph node metastasis. Conclusions: ER and PR expression in breast cancers in the current study was found to be higher than studies done in India/Asia but lower than studies conducted in the West, even on Indian/Asian immigrants. Markedly lower receptor expression in Indian/Asian studies is likely due to preanalytic variables, thresholds for positivity, and interpretation criteria. American Society of Clinical Oncology/College of American Pathologists Guideline Recommendations for Immunohistochemical Testing of Estrogen and Progesterone Receptors in Breast Cancer are strongly advocated for standardization of receptor evaluation and for clinical management of breast cancer patients to provide best therapeutic options.

  • Background: It is estimated that 20-30% of ginseng crops in Canada are lost to root rot each harvest. This disease is commonly caused by fungal infection with Ilyonectria, previously known as Cylindrocarpon. Previous reports have linked the virulence of fungal disease to the production of siderophores, a class of small-molecule iron chelators. However, these siderophores have not been identified in Ilyonectria. Methods: High-resolution LC-MS/MS was used to screen Ilyonectria and Cylindrocarpon strain extracts for secondary metabolite production. These strains were also tested for their ability to cause root rot in American ginseng and categorized as virulent or avirulent. The differences in detected metabolites between the virulent and avirulent strains were compared with a focus on siderophores. Results: For the first time, a siderophore N,N',N"-triacetylfusarinine C (TAFC) has been identified in Ilyonectria, and it appears to be linked to disease virulence. Siderophore production was suppressed as the concentration of iron increased, which is in agreement with previous reports. Conclusion: The identification of the siderophore produced by Ilyonectria gives us further insight into the root rot disease that heavily affects ginseng crop yields. This research identifies a molecular pathway previously unknown for ginseng root rot and could lead to new disease treatment options.

  • Options available for utilization of animal wastes include sources of plant nutrients, feed ingredients for farm animals, substrate for methane generation, and substrate for microbial and insect protein synthesis. The wastes have the most economic value for use as animal feed. Performance of animals fed diets containing animal wastes is similar to that of animals fed conventional diets. Processing of animal wastes to be used as animal feed is necessary for destruction of pathogens, improvement of handling and storage characteristics, and maintenance or enhancement of palatability. Feeding of animal waste has not adversely affected the quality and taste of animal products. In the USA copper toxicity has been reported in sheep fed high-copper poultry litter, but this is not a serious problem with cattle. Potential pathogenic microorganisms in animal wastes are destroyed by processing such as heat treatment, ensiling and deep stacking. Incidents of botulism, caused by Clostridium botulinum, have been reported in cattle in some countries, and this problem was caused by the presence of poultry carcasses in litter. This problem has not occurred in the USA. With appropriate withdrawal, heavy metal, pesticide or medicinal drug accumulation in edible tissues of animals fed animal wastes is not a problem. Feeding of animal wastes is regulated by individual states in the USA. The practice is regulated in Canada, also. With good management, animal wastes can be used safely as animal feed.

  • The purpose of this study is to discuss the modern fashion design that incorporates national flags, by each country, methods of their expressions and distinct characteristics. Moreover, it intends to contribute in creating the image of Korea and our own unique fashion identity through creative designs that coincides with the modern trend by adopting Taegeukgi. The results of this study can be summarized as follows: The American flag and the British Union Jack were molt widely used and even though it was less frequent, flags of the France, Korea, Israel, Germany as well as Argentina have been featured in modern fashion. The expression methods also varied and it demonstrated the unlimited options as to how a flag can be presented. Some used the traditional flag as is. Some only used a portion of a flag or its colors as a motive or sometimes the flags were completely redesigned. There are distinctive characteristics when flags are incorporated into fashion. First, the shapes or colors of the flags were used to emphasize the image of a country in rather simple silhouette without many details. Second, through altered shapes, shades, colors or rearrangement, the country's image is presented in more subtle, indirect manner. Third, a flag is a mere element of a formation with various changes to its shape or color, and it no longer holds the traditional significance of a flag. It may also represent the playful or ironic image by combining with other items or execution techniques.
