  • The purpose of this study was to identify levels of hearing handicap, depression, and self-efficacy, and to determine the effect of hearing handicap on depression and self-efficacy in home-based elderly. Data were collected from August to September 2017. Two hundred and seventy eight elderly living at home in three cities participated in this study. Data were analyzed using the independent t-test, one-way ANOVA, Scheffe's test, Pearson's correlation coefficients, and by multiple regression analysis using SPSS Ver. 20.0 for Windows. Mean levels of hearing handicap, depression, and self-efficacy were 10.91 (${\pm}19.83$), 4.75 (${\pm}3.90$), and 46.87 (${\pm}6.75$) respectively. A statistically significant positive correlation was observed between hearing handicap and depression (r=.228, p<.001), and significant negative correlations were found between hearing handicap and self-efficacy (r=-.284, p<.001) and between depression and self-efficacy (r=-.526, p<.001). Hearing handicap had a negative effect on self-efficacy (${\beta}=-.161$, p=.008) and its explanatory power was 27.2%. The study results suggest that the developments of multidisciplinary interventions and education programs are important to prevent or minimize hearing handicap in the elderly.

  • Changes of physicochemical properties of brined cucumber were investigated in the samples mixed cucumber and water at 1 : 1.2 ratio in various salt concentrations from 15 to 30%. As salt concentrations in brine solutions were increased, cucumber was getting constricted and decreased in the size of diameter. Salt concentrations of brined cucumber were reached an equilibrium after 30 days of brine storage. When cucumber was preserved at 30% salt concentration, pH was gradually decreased until 60 days of brine storage. When cucumber was preserved in 15% salt solution, the yellowness on the surface of cucumber peels was the most intense among the groups. Among the groups preserved by more than 20% of salt, no difference was observed in intensity of yellowness after 30 days of brine storage. The absorbances of isopropyl alcohol extracts at 410, 505, 607, and 665 nm were different from those of raw cucumbers. Regardless of salt concentration, the hardness of cucumber was increased as preservation was prolonged except the group preserved in 15% salt solution.

  • Purpose: The aim of this study was to evaluate the validity and reliability of the Korean version of the Clinical Teaching Behavior Inventory (CTBI). Methods: The English CTBI-23 was translated into Korean with forward and backward translation. Survey data were collected from 280 nurses' preceptors at five acute-care hospitals in Korea. Content validity, construct validity, and criterion-related validity were evaluated. Cronbach's ${\alpha}$ was used to assess reliability. SPSS 24.0 and AMOS 22.0 software was used for data analysis. Results: The CTBI Korean version consists of 22 items in six domains, including being committed to teaching, building a learning atmosphere, using appropriate teaching strategies, guiding inter-professional communication, providing feedback and evaluation, and showing concern and support. One of the items in the CTBI was excluded with a standardized factor loading of less than .05. The confirmatory factor analysis supported good fit and reliable scores for the Korean version of the CTBI model. A six-factor structure was validated ($x^2=366.30$, p<.001, CMIN/df=2.0, RMSEA=.06, RMR=.03, SRMR=.05, GFI=.90, IFI=.94, TLI=.92, CFI=.94). The criterion validity of the core competency evaluation tool for preceptors was .77 (p<.001). The Cronbach's ${\alpha}$ for the overall scale was .93, and the six subscales ranged from .72 to .85. Conclusion: The Korean version CTBI-22 is a valid and reliable instrument for identifying the clinical teaching behaviors of preceptors in Korea. The CTBI-22 also could be used as a guide for the effective teaching behavior of preceptors, which can help new nurses adapt to the practicalities of nursing.

  • The present study attempted to impregnate alkali metals to amino acid in order to improve $CO_2$ absorption capacity. A used amino acid was glycine, of which pH increased up to about 11 with the addition of alkalies. $CO_2$ absorption capacity of amino acid salts was evaluated in a batch and a continuous process. The absorption capacity appeared in turns as; Sodium Glycinate ${\geq}$ Lithium Glycinate > Potassium Glycinate. Amino acid salts showed lower absolute capacity of $CO_2$ absorption than primary amine (Monoethanolamine) at $20^{\circ}C$. In a continuous absorption with 10% $CO_2$ flow, the increasing the reaction temperature, the increasing rate of absorption for amino and was higher that of than amino absorbent.

  • Protein-Protein Interactions (PPIs) play essential roles in diverse biological processes and their misregulations are associated with a wide range of diseases. Especially, the growing attention to PPIs as a new class of therapeutic target is increasing the need for an efficient method of cell-based PPI analysis. Thus, we newly developed a robust PPI assay (SeePPI) based on the co-translocation of interacting proteins to the discrete subcellular compartment 'processing body' (p-body) inside living cells, enabling a facile analysis of PPI by the enriched fluorescent signal. The feasibility and strength of SeePPI (${\underline{S}}ignal$ ${\underline{e}}nhancement$ ${\underline{e}}xclusively$ on ${\underline{P}}-body$ for ${\underline{P}}rotein-protein$ ${\underline{I}}nteraction$) assay was firmly demonstrated with FKBP12/FRB interaction induced by rapamycin within seconds in real-time analysis of living cells, indicating its recapitulation of physiological PPI dynamics. In addition, we applied p53/MDM2 interaction and its dissociation by Nutlin-3 to SeePPI assay and further confirmed that SeePPI was quantitative and well reflected the endogenous PPI. Our SeePPI assay will provide another useful tool to achieve an efficient analysis of PPIs and their modulators in cells.

  • The wastewater treatment with a two-phase expanded granular sludge bed (EGSB) system for anaerobic degradation of acetate, benzoate, terephtalate and p-toluate from purified terephtalic acid (PTA) production was studied. The feasibility and effectiveness of the system was evaluated in terms of organic oxidation by chemical oxygen demand (COD), gas production, bacterial adaptability and stability in the granular sludge. Average removal efficiencies 93.5% and 72.7% were achieved in the EGSB reactors under volumetric loading rates of $1.0-15kg-COD/m^3/day$ and terephtalate and p-toluate of 351-526 mg/L, respectively. Gas production reached total methane production rate of 0.30 L/g-COD under these conditions in the sequential EGSB reactor system. Higher strength influent COD concentration above 4.8 g-COD/L related to field conditions was fed to observe the disturbance of the EGSB reactors.
