To determine the suitability of groundwater quality for agricultural use in the Gyeong-buk Province, the chemical properties of groundwater were analyzed from 2021 to 2024. pH, electric conductivity (EC), total nitrogen (T-N), total phosphorus (T-P), nitrate nitrogen (NO3-N), chloride ion (Cl-), sodium (N), magnesium (Mg), potassium (K), and calcium (Ca) were measured in April and July every year and analyzed by land use type. Ca and T-P showed little differences regardless of the type of land use. The T-N in upland fields was lower compared to other land use types, but the pH was higher. The concentrations of Cl-, Na, Mg, K, and Ca in groundwater were highest in the greenhouse fields, but there was no clear differences between year-to-year or April and July. NO3-N and Cl- concentrations maintained good water quality that did not exceed the agricultural groundwater standard for four years. The pH also met agricultural standards during the survey period, as it recorded pH 5.8, below the standard, at just one point of the water sample taken from green house in April 2023. The results obtained in the study implying that agricultural groundwater in Gyeong-buk Province was generally suitable for agricultural purpose.
항진균제 감수성 검사의 최신지견: 검사법과 임상적 이용

During the past two decades, Clinical and Laboratory Standards Institute (CLSI) antifungal susceptibility testing methods for both yeasts and molds have been developed and established in response to increasing invasive fungal infections and the release of multiple new antifungal agents. In addition, other methods including Etest, the disk diffusion test, and some CLSI modification methods have been intensively studied. Antifungal susceptibility tests are now routinely used for local epidemiological surveys to determine the susceptibility patterns of clinical isolates of fungi, the degree of antifungal activity of newly developed antifungal agents, and to predict the clinical outcomes of antifungal therapy for patients with Candida infections. It is anticipated that in the near future, antifungal susceptibility tests that can detect amphotericin B resistance, that can be used to establish the minimum inhibitory concentration (MIC) breakpoints of molds, and that can provide increased clinical guidance for antifungal therapy, will be developed. This review focuses on the various methods used for antifungal susceptibility testing and the clinical utility of antifungal susceptibility testing.
Exophiala (Wangiella) dermatitidis에 의한 진균혈증 1예

We report a rare case of fungemia due to Exophiala (Wangiella) dermatitidis in a 4-month-old female infant who was admitted to an intensive care unit with sudden infant death syndrome (SIDS). E. dermatitidiswas repeatedly isolated from blood cultures (on the 28th and 32nd day of hospitalization) of the patient,who died on the 44th day of hospitalization. The fungus was identified by its morphological characteristics and DNA sequencing of both the D1/D2domain and the ITS region of rDNA. To our knowledge,this is the first reported case of E. dermatitidis fungemia in Korea. (Korean J Clin Microbiol 2010;13:135-139)

Rice ratooning is the cultural practice that easily produces secondary rice from the stubble left behind after harvesting the main crop. ‘Daol’ is an extremely early growing rice variety. Planting this variety early allows for an additional ratoon harvest after the primary rice harvest. The plant growth and yield of ratoon rice were very low compared to those of main rice. Protein, amylose content, and head rice rate were higher in ratoon rice than in main rice. The distribution by the rice flour particle size of main and ratoon rice was similar. The damaged starch content in ratoon rice was relatively high at 6.1%. Ratoon rice required a longer time and higher temperature for pasting than main rice. Compared to the original rice, peak viscosity (PV), hot paste viscosity (HPV), cool paste viscosity (CPV), and breakdown (BD) were very low, and setback (SB) was high. As a result of analyzing the gelatinization properties of main and ratoon rice using differential calorimetry, it was found that the onset (To),peak (Tp), and conclusion (Tc) of ratoon rice starch were processed at a lower temperature than those of main rice. The gelatinization enthalpy of both samples was similar. The distribution of amylopectin short chains in ratoon rice was higher than that in main rice.
