This study was conducted to investigate and analyze food related and space related elements of popular Vietnamese restaurants in Hong Kong to identify restaurant images related to food, to examine how Vietnamese traditions are applied to such restaurants, and ultimately, to get their implications for us. Luxury Vietnamese restaurants in Hong Kong tended to be located in major office buildings and famous shopping malls in the downtown area; therefore, they were highly accessible to foreigners. In addition, most Vietnamese restaurants were quite formal in size or atmosphere. The food-related elements of the luxury restaurants reproduced traditional menus, but the table setting and service generally adopted a formal Western style setting. The presentation of foods was also creative and contemporary, to suit international customers' tastes. Regarding the spatial elements, restaurants serving traditional menus had interiors influenced by the French colonial period, while those serving contemporarily adapted menus had interiors with simple contemporary images emphasized by Vietnamese traditional decorations. These characteristics allowed foreigners from diverse countries to access the restaurants without a sense of rejection. Casual restaurants were primarily exposed to many people on busy roadsides, but they tended to be inferior in terms of size and quality. Apart from size and price level, food-related elements failed to reflect Vietnamese unique traditional characteristics. The outward appearance consisted of basic construction materials (glass, chassis, and bamboo) instead of those representing Vietnamese architecture. Additionally, the interior of the casual restaurants contained traditional elements or objects more frequently than luxury restaurants, but they looked rather disorderly and lacked harmony. Overall, the image of casual restaurants was degraded by the use of cheap and low quality finishing materials and furniture. The results of this study may be useful for organizations promoting the Branding of Korea or businesspeople and designers promoting the globalization of Korean foods.

C3 glomerulopathy (C3G) is a recently defined pathological entity characterized by C3 accumulation with absent or scant immunoglobulin deposition, leading to variable glomerular inflammation. The clinical presentation of patients with C3G is highly variable, as they may present with symptoms ranging from microscopic or mild proteinuria to full-blown nephrotic syndrome, with or without renal impairment. However, there is no consensus recommendation for specific treatment in children with C3G. Recently, new therapies have been suggested to target complement pathways, owing to an improvement in the understanding of the pathogenesis of C3G. C3G complement blockade with eculizumab, a monoclonal antibody targeted against complement C5, inhibits activation of the alternative complement pathway. We could not use eculizumab owing to its high price; thus, we administered oral prednisolone and mycophenolate mofetil (MMF). MMF was replaced with cyclosporine because proteinuria persisted, with a consistently low serum C3 level; we tapered off the prednisolone because of a Cushingoid appearance and amenorrhea. Thereafter, proteinuria improved, and the serum C3 level returned to normal. Thus, we report the effectiveness of cyclosporine in a patient with C3G and an inadequate response to prednisolone and MMF, who was detected via school urinary screening.

This article provides the definitions of the negotiation of credit, the negotiating bank and the negotiation credit. It further describes a number of legal status of negotiating banks by looking into the legal relations firstly between the beneficiary and the negotiating bank and secondly between the issuing bank and the negotiating bank. This study is in large part based on relevant provisions of UCP 600 and decisions of the Supreme court of South Korea. Under UCP 600 the definition of negotiation requires the purchase by the nominated negotiating bank of the required documents by advancing funds on or before the banking day on which reimbursement is due to the negotiating bank. A negotiation credit authorizes the negotiating bank who is a nominated bank to purchase from the beneficiary the documents required by the letter of credit and to present those documents to the issuing bank for reimbursement. If the credit is to be honoured at sight, reimbursement is due when the issuing bank determines that there has been a conforming presentation. Reimbursement under a letter of credit available by acceptance or by deferred payment is due at maturity of the credit. In particular, while the timing of advance by the nominated negotiating bank is up to the parties, a promise of the negotiating bank to advance the purchase price to a fraudulent beneficiary does not confer immunity from letter-of-credit fraud prior to its performance. This requires the negotiating bank who is notified of material fraud prior to making an advance to beneficiary to avoid a loss by using the fraud.

Interests in the field of rapid methods and automation in microbiology have been growing steadily on an international scale in recent years. International meetings concerned this problem have been held in elsewhere in the world countries since the past twenty years. But, unfortunately in the field of microbial examination in food hygiene, this problem have not yet been developed so much as in the field of clinical microbiology. Today, I would like to introduce you here present aspects of rapid and automation technologies, those which are manly carrying in milk and meats industries. My illustration will be given recent improved technologies using automatic apparatus and instruments along with process of microbial count procedure. Recent direct microbiological counting system (ChemeScan \ulcorner) as real time ultrasensitive analysis created by Cheminex Ltd., France is now most evolutional instrument to provide direct microbial counts, down to one cell, within 30 minutes. The results from these evaluations how a good correlation between the ChemScan system and the standard plate count method. This system will be successful application for not only in the field of pharmacology but also food microbiology. In addition, current identification of microbes by sophisticated instruments suitable for food microbiology, one of which Biology is manual system (BIOLOG\ulcorner), provides reference-level capability at a modes price. For the manual system, the color reactions in the microplate are read by eye and manually keyed into personal computer. Species identification appears on the computer screen within seconds, along with biotype patterns, a list of closely related species, and other useful statistics. In present this is useful application for microbial ecology and epidemiological survey. RiboPrinter system newly produced by DuPont is now focusing among microbiologists in the world, and is one of the biggest microbial characterization system using a DNA-based approach. The technology analyzer is bacterial culture for its genetic fingerprint or riboprint pattern. Finally Bio-cellTracer system for automatic measurement of fungal growth and Fukitori-Maseter, a Surface Hygiene Monitoring Kit by using swabe procedure in food processing environment are briefly illustrated in this presentation.

Objectives: Transformation through a sustainable food system to provide healthy diets is essential for enhancing both human and planetary health. This study aimed to explain about sustainable diets and illustrate appropriate measurement of adherence to sustainable diets using a pre-existing index. Methods: For literature review, we used PubMed and Google Scholar databases by combining the search terms "development," "validation," "sustainable diet," "sustainable diet index," "planetary healthy diet," "EAT-Lancet diet," and "EAT-Lancet reference diet." For data presentation, we used data from National Health and Nutrition Examination Survey, 2017-2018, among adults aged 20 years and older (n = 3,920). Sustainable Diet Index-US (SDI-US), comprising four sub-indices corresponding to four dimensions of sustainable diets (nutritional quality, environmental impacts, affordability, and sociocultural practices), was calculated using data from 24-hour dietary recall interview, food expenditures, and food choices. A higher SDI-US score indicated greater adherence to sustainable diets (range: 4-20). This study also presented SDI-US scores according to the sociodemographic status. All analyses accounted for a complex survey design. Results: Of 148 papers, 16 were reviewed. Adherence to sustainable diets fell into 3 categories: EAT-Lancet reference diet-based (n = 8), Food and Agriculture Organization (FAO) definition-based (n = 4), and no specific guidelines but including the sustainability concept (n = 4). Importantly, FAO definition emphasizes on equal importance of four dimensions of diet (nutrition and health, economic, social and cultural, and environmental). The mean SDI-US score was 13 out of 20 points, and was higher in older, female, and highly educated adults than in their counterparts. Conclusions: This study highlighted that sustainable diets should be assessed using a multidimensional approach because of their complex nature. Currently, SDI can be a good option for operationalizing multidimensional sustainable diets. It is necessary to develop a Korean version of SDI through additional data collection, including environmental impact of food, food price, food budget, and use of ready-made products.
