This study was analyzed the syllable structure of Korean and Chinese using subjective sound similarity judgement tasks with both Korean-chinese and Chinese students in Shenyang, China. 86 college students were administered with the tasks which lasted about 20 min. in a small group setting. Both Korean-chinese and Chinese students showed the sensitivity for the CV sub-syllabic unit and the CV+C was the building block for phonetic representation for both languages. This syllabic similarity of Korean and Chinese may be a help for Korean-chinese to become horizontal bilinguals. Further studies are needed to specify the mechanism that will explain the syllabic perception of CV+C in both Korean and Chinese which was different from that of C+VC structure dominance in English.

Neurotransmitter glycine in the nano gram range was analyzed using a paste electrode (PE) in cyclic voltammetry (CV) and square-wave stripping voltammetry (SWSV). An anodic peak caused by oxidation of the glycine ion appeared at the 0.4 V (versus Ag/AgCl/KCl) potential in a 0.1 M NH4H2PO4 electrolyte solution. At optimized conditions, the working range of the SWSV and CV concentration was found to be 5-60 ngL-1 glycine; precision of R2 = 0.9816 (SWSV) and 0.9986 (CV); and detection limit of 0.65 ngL-1 (5.82 × 10-12 molL-1) (S/N = 3). The optimized conditions were applied to an assay in a fish brain tissue and a living brain cell in real time.

Purpose: Chemical fertilizers contribute to agricultural productivity. Annually, 450,000 tons of chemical fertilizers are used in Korea, which is 268 kg per hectare (MAFRA, 2016). However, excessive use causes problems such as environmental pollution and soil acidification. This study proposes use conditions for a fertilizer distributor that can reduce excessive fertilization by analyzing distribution patterns. Methods: This study analyzed fertilizer application uniformity according to the number of blades on a centrifugal fertilizer distributor (three or four blades), orifice gate open ratio (50 or 100%), and blade rotation speed (400, 500, or 600 rpm). Results: When using four blades, the coefficient of variation (CV) was lower than when using three by 11-13% points, and the CV using the 50% open ratio was 10-30% points lower than using the 100% open ratio. The CV at 500 rpm blade rotating speed was 9-12% points lower than that for 400 and 600 rpm. Conclusions: The CV with four blades, 50% orifice gate open ratio, and 500 rpm of blade rotating speed was 18.4%, which provided the most uniform fertilization.

Totally sixty three bacteria were isolated from lower stems showing symptoms of bacterial wilt on pepper plants in 14 counties of 7 provinces, Korea. The isolates showed strong pathogenicity on red pepper (cv. Daewang) and tomato (cv. Seogwang) seedlings. All virulent bacteria were identified as Ralstonia solanacearum based on colony types, physiological and biochemical tests and polymerase chain reaction (PCR). All R. solanacearum isolates from peppers were race 1. The bacterial isolates consisted of biovar 3 (27%) and biovar 4 (73%). Based on polymorphic PCR bands generated by repetitive sequence (rep-PCR), the 63 R. solanacearum isolates were divided into 12 groups at 70% similarity level. These results will be used as basic materials for resistant breeding program and efficient control against bacterial wilt disease of pepper.

Background: Goslings in several Taiwanese farms experienced gosling feather loss disease (GFL) at 21-35 days and goose broke feather disease (GBF) at 42-60 days. The prevalence ranges from a few birds to 500 cases per field. It is estimated that about 12,000 geese have been infected, the morbidity is 70-80% and the mortality is 20-30%. Objectives: This study aims to investigate the pathogens that cause GFL and GBF. Focus on the study of the correlation between goose circovirus (GoCV) and goose parvovirus (GPV) with the goose feather loss in southern Taiwan. Furthermore, a phylogenetic tree was established to align the differences between southern and northern Taiwan and compare with virus strains from China and Europe. Methods: Samples were collected from animal hospitals. Molecular and microscopy diagnostics were used to examine 92 geese. Specific quantitative polymerase chain reaction (Q-PCR) assays are performed to evaluate GPV and GoCV viral loads and simultaneously evaluated the feather loss conditions in geese with the scoring method. Results: High prevalence of GoCV and GPV infection in geese showing signs of GFL and GBF. Inclusion body was detected in the feather follicles and Lieberkuhn crypt epithelial cells. The Q-PCR showed the high correlation between feather loss and viruses during 3rd-5th week. However, the infection was not detected using the same test in 60 healthy geese. Conclusions: Thus, GFL and GBF appear to be significantly closely related to GoCV and GPV. The geese feathers showed increasing recovery after being quarantined and disinfected.

The purpose of this study is to observe the effectiveness of the Korean medical complex treatments for functional dyspepsia (FD). And we observed NDI-K (Nepean dyspepsia index-Korean version) and algometer on acupoints to confirm the treatment effectiveness. In this retrospective study, we investigated 77 patients with FD symptoms who admitted to 00 Korean Hospital for 2 weeks from April 14, 2020 to March 31, 2021. All patietns were treated with herbal medicines, acupuncture, pharmacopuncture, moxa treatment, aroma therapy, So-jeok and So-jeok II therapy. On the day of admission and discharge, NDI-K, algometer on acupoints (CV12, CV10, ST25, ST27, SP14) were examined twice. Among the NDI-K values, all 14 items except for poor breathing were decreased statistically significantly. The algometer values were increased statistically significantly in all acupoints (CV12, CV10, ST25, ST27, SP14). These results suggest that Korean medical treatment can be useful in the treatment of FD.

Purpose: This research is to investigate the needling Depth for Deqi based onone's age, weight, and the level of obesity and the different Deqi sensation in Chung-wan and Kwan-wan. Methods: We took a research on Deqi for the 123 patients who visited a local Korean Medicine clinic at random. The variants were the age, the weight, thetotal fat rate, the waist-hip rate, BMI, the weight size, and the Sasang constitution. Result: Older patients need more depth of Deqi in Chung-wan and Kwan-wan compared to the younger ones. The higher the level of obesity(weight, total body fat rate, the waist-hip rate, BMI) goes up, the more Deqi in Chung-wan and Kwan-wan goes deeply. As the level of obesity goes down in the order of Taeeum-in, Soyang-in, Soeum-in, the depth of Deqi also decreases in Chung-wan and Kwan-wan. Deqi in Chung-wan is the feeling of pressure around the acu-point, and Deqi in Kwan-wan is the feeling that it spreads out to the upper, lower, the right, and the left side of the acu-point. Conclusion: In case of Needling Depth for Deqi on Chung-wan and Kwan-wan, that increases or decreases as the age, the level of obesity(the physique), and the Sasang constitution changes.
