This study was performed to analyze general components such as, organic acids, alcohols and minerals in persimmon vinegar made with quick fermented using deteriorated sweet persimmon and four commercial vinegars(rice vinegar, apple vinegar, brewed vinegar, traditional persimmon vinegar) purchased in local markets for quality evaluation. The pH and total acidity of all vinegars were in the range of 2.02~3.02 and 4.62~9.78%, respectively. The pH of quick fermented persimmon vinegar(A) was relatively higher than that of others. Acidity was the highest in brewed vinegar. Total sugar content was in the range of 0.45~6.43%. These contents were high in were high in traditional persimmon vinegar wherase low in brewed vinegar. Total nitrogen and amino-nitrogen were in the range of 0.025~0.046% and 0.015~0.029%. Organic acids were identified as acetic acid, citric acid, tartaric acid, malic acid, succinic acid, formic acid and oxalic acid. While major minerals of all vinegars were Mg, Ca, and Na, minor minerals were Zn, Cu, Mn and Fe.

본 연구에서는 장애아 부모들이 경험하는 스트레스와 대처를 보다 명확하게 규명하기 위하여 장애아 부모(62명)와 정상아 부모(135명)를 비교하였다. 그 결과, 정서적 스트레스와 관련해서는 장애아 부모가 정상아 부모에 비하여 상태 분노, 특성 분노, 분노 표출, 및 우울에서 유의하게 높게 나타났다. 또한 대처 방식과 관련해서는 장애아 부모가 정상아 부모에 비하여 소극적 철수, 고집, 체념 및 자기 비판에서 유의하게 높게 나타났다. 끝으로, 신체증상과 관련해서는 장애아 무모가 정신아 부모에 비하여 불면증과 심장 질환 증상에서 유의하게 높게 나타났다. An attempt was made to compare the parents of children with disabilities and those of normal children in terms of their emotional stress and coping styles. The scales utilized in the present study were Korean adaptation of STAXI, the multidimensional coping scale, and Korean adaptation of CES-D. The major findings revealed that (1) the parents of children with disabilities compared to those of normal children showed higher levels of state anger, trait anger, and depression. (2) The parents of children with disabilities compared to those of normal children employed more frequently 'passive withdrawal,' 'perseverance,' 'fatalism,' and 'self-criticism', suggesting that they are more frequently employing ineffective coping styles. (3) The parents of children with disabilities compared to those of normal children were suffering from insomnia and cardiac symptoms. Finally, the present findings were discussed and implications for future studies are suggested.

An acidic ent-cyclic peroxide was isolated from a sponge, Plakotis sp., and showed activity against leishmaniasis and pathogenic fungi. To improve the activity of this compound, we coupled the acidic ent-cyclic at the C1 position of ircinol A. Compound 3 exhibited significant activity against Leishmania mexican a and fungi with $IC_{50}$ values of 0.7 and $0.3-34{\mu}g/mL$, respectively. The yield of compound 3 was 98%.

Background/Aims: The multidisciplinary team (MDT) approach is a cornerstone of clinical oncology. This study investigated the current state of MDT care, including patient satisfaction, in Korea. Methods: We obtained the annual number of cancer patients who have received MDT care since 2014 from the registry of the Health Insurance Review and Assessment Service (HIRA). In addition, patients who received MDT care from August 2014 to May 2017 at four university hospitals were further characterized, and patient satisfaction was measured prospectively using a patient-reported questionnaire. Results: The total number of patients who received MDT care increased from 2014 to 2016 (2,113 to 9,998 patients, respectively) in the HIRA Cohort. The type of cancer that most often required MDT was breast cancer (23.8%), followed by colorectal cancer (19.1%). In the Representative Cohort (n = 1,032), MDT was requested by the surgeon more than half the time (55.7%). The main focus of MDT was decision making for further treatment planning (99.0%). The number of doctors participating in the MDT was usually five (70.0%). After initiating an MDT approach, the treatment plan changed for 17.4% of patients. Among these patients, 359 completed a prospective satisfaction survey regarding their MDT care. The overall satisfaction with the MDT approach was very high, with an average score of 9.6 out of 10 points. Conclusions: The application of MDT care is a rapidly growing trend in clinical oncology, and shows high patient satisfaction. Further research is needed to determine which types of cancer patients could benefit most from MDT, and to enable MDT care to operate more efficiently so that it may expand successfully throughout Korea.

According to the building regulation U-value limitation of window is 3.3W/㎡·K in southern regions, while U-value limitation of wall is 0.35~0.58W/㎡·K. It means that the energy loss through windows is five times more than it through wall. Therefore, this study analyze how much it has affected building energy rating when the insulation performance of windows and walls is changed by building regulation. In conclusion, in order to obtain 2 rating thermal performance of windows is improved more than 10 percent of U-value limitation and it of wall is improved more than 20 percent. The thermal performance of windows is improved more than 20 percent of U-value limitation and it of wall is improved more than 30 percent to receive 1 rating.

Purpose: Nondestructive evaluation of seed viability is a highly demanded technique in the seed industry. In this study, hyperspectral imaging system was used for discrimination of viable and non-viable radish seeds. Method: The spectral data with the range from 400 to 1000 nm measured by hyperspectral reflectance imaging system were used. A calibration and a test models were developed by partial least square discrimination analysis (PLS-DA) for classification of viable and non-viable radish seeds. Either each data set of visible (400∼750 nm) and NIR (750∼1000 nm) spectra and the spectra of the combined spectral ranges were used for developing models. Results: The discrimination accuracy of calibration was 84% for visible range and 76.3% for NIR range. The discrimination accuracy of test was 84.2% for visible range and 75.8% for NIR range. The discrimination accuracies of calibration and test with full range were 92.2% and 92.5%, respectively. The resultant images based on the optimal PLS-DA model showed high performance for the discrimination of the nonviable seeds from the viable seeds with the accuracy of 95%. Conclusions: The results showed that hyperspectral reflectance imaging has good potential for discriminating nonviable radish seeds from massive amounts of viable seeds.
