Since the 1990s, the application of Kentucky bluegrass cultivars has increased in newly-constructed Korean golf courses as opposed to the previously-used zoysiagrass. However, there have been few reports studying the selection and characterization of these Kentucky bluegrass cultivars under Korean weather conditions. A total of 12 Kentucky bluegrass cultivars were tested for their adaptability in environmental stresses during summer conditions in Korea in order to select the best Kentucky bluegrass cultivars for use in Korean golf courses. This study found that two Kentucky bluegrass cultivars ('Midnight' and 'Bluestone') maintained their green throughout the summer season and had a high degree of root density, as compared to the other cultivars tested. These two cultivars also had a good rate of coverage in the early growth period. These characteristics make them suitable for application on sports fields and golf courses, which receive many divots and the frequent replacement of turfgrass sod caused by both biotic and abiotic stress. Two other cultivars, the 'Ginney' and 'Nuglade', also displayed good visual quality and high rate of coverage under summer conditions. In conclusion, the 'Midnight' and 'Bluestone' cultivars performed well in areas including the maintenance of their green color, the number of roots and the rate of coverage during the summer months. These characteristics are necessary for golf courses sports fields, which receive many divots and requirethe frequent replacement of turfgrass. further research on a range of Kentucky bluegrass cultivars, including a sensitivity test for many pathogens and recovery rates from a variety of stresses, is required in the near future.

김경덕(Kim, Gyung-Duck),김경혜(Kim, Kyung-Hae) 한국산학기술학회 2015 한국산학기술학회논문지 Vol.16 No.9

본 연구의 목적은 한국과 뉴질랜드 노인의 국가 간 우울, 불안, 스트레스 정도의 차이를 파악하기 위한 서술적 조사연 구이다. 연구 대상은 60세 이상의 남녀 재가노인으로 뉴질랜드 55명과 성별로 짝짓기를 하여 한국 55명으로 총 110명을 분석 하였다. 자료 수집은 2013년 1월 24일부터 2월 10일까지 구조화된 설문지로 직접 면접을 통하여 수집하였다. 연구 결과, 우울 정도는 한국 13.67/42점으로 뉴질랜드 4.70/42점보다 높았다. 불안 수준은 한국 11.42/42점으로 뉴질랜드 4.92/42점보다 높게 나타났다. 또한 스트레스 수준은 한국 13.54/42점으로 뉴질랜드 5.40/42점보다 높게 확인되었다. 노인의 우울, 불안 및 스트레 스 간의 상관관계는 우울은 불안과 스트레스와 순 상관관계를 보였으며, 불안 또한 스트레스와 순 상관관계를 보였다. 본 연구를 통하여 한국 노인의 노년기 삶의 질 향상을 위해서 우울, 불안 및 스트레스를 감소시키는 프로그램의 개발 및 적용되 어야 할 것으로 사료된다. This study was done to identify differences in depression, anxiety, and stress in Korea elders (n=55) and New Zealand elders (n=55). Methods: This study was conducted from January 24th, 2013 to February 10th, 2013. We individually matched Korea elders to New Zealand elders based on age and sex, and assessed a questionnaire regarding depression, anxiety, and stress. Results: The average depress score for the Korea elders (13.67/42) was significantly different to the average for the New Zealand elders (4.70/42). The average anxiety score for the Korea elders (11.42/42) was significantly different to the average score for the New Zealand elders (4.92/42). The average stress score for the Korea elders (13.54/42) was significantly different to the average score for the New Zealand elders (5.40/42). The depression score showed a significant relationship with anxiety and stress. There was significantly positive correlation between anxiety and stress. The study suggests that should be considered in developing nursing intervention to manage depress, anxiety, and stress of the Korea elderly people.

항암화학요법으로 인한 유방암 환자의 인지기능 측정도구 사용 실태 분석

Purpose: This study analyzed recent trends of instrument usage assessing cognitive function of breast cancer patients undergoing chemotherapy. Methods: The researcher collected 64 studies outside the country that were published between January 1996 and August 2010. Results: There was no study on the instrument assessing all domains of cognitive function in breast cancer patients undergoing chemotherapy. Most instruments assessing cognitive function of breast cancer patients have been used for patients with dementia depression and/or organic brain damage. Also the objective neuropsychological tests such as the grooved pegboard for the psychomotor area RCFT copy in visuospatial skill area and the WAIS-III block design have low sensitivity for measuring cognitive function in breast cancer patients thus they are not good for applying to breast cancer patients. Conclusion: There is a need to develop an instrument which has good sensitivity and specificity for measuring the cognitive function of the breast cancer patients who experienced cognitive impairment after chemotherapy treatment. In addition the developed instrument needs to be accessible and feasible in any nursing clinical setting for the purpose of accurate assessment and evaluation of the cognitive function among breast cancer patients.

Purpose: This study was to compare climacteric symptoms and cognitive impairment in breast cancer survivors (n=51) and healthy women (n=51). Methods: This study was conducted from January 4th, 2012 to February 16th, 2012. We individually matched healthy women to breast cancer survivors based on age and education, and assessed a questionnaire regarding climacteric symptoms and cognitive impairment. Data were analyzed by using χ², t-test, and Pearson correlation with the SPSS/Win 12.0 program. Results: The average score for the climacteric symptoms (19.71) was significantly different (t=-2.78, p=.006) to the average for the breast cancer survivors (15.53). The average cognitive impairment score for the breast cancer survivors (86.37) was significantly different (t=-2.45, p=.016) to the average score for the healthy women (67.92). The climacteric symptoms score showed a significant relationship with cognitive impairment. Conclusion: These results support that adjuvant chemotherapy and anti-hormone therapy are associated with climacteric symptoms and adverse cognitive effects in breast cancer survivors.

김경덕 ( Kyung Duck Kim ),류μ영 ( Young Ryu ),김석찬 ( Seok Chan Kim ) 한국공업화학회 2014 공업화학 Vol.25 No.3

본 연구의 내용은 Dimethyl terephthalate의 생성 과정 중 필연적으로 생성되는 부산물인 Methyl 4-formylbenzoate를 이용해 one-pot reaction을 통한 p-Aminobenzoic acid를 얻는 방법이다. 이 방법은 Methyl 4-formylbenzoate에 chlorine gas와methylene chloride를 이용해 acid chloride를 형성하고 ammonia gas를 통해 amide를 중간체로 가진다. 생성된 amide는Hofmann degradation을 통해 p-Aminobenzoic acid로 전환된다. 이 방법은 폐기물인 Methyl 4-formylbenzoate를 재활용하여 기존의 p-Aminobenzoic acid를 수율 90%로 합성하였으며 이는 기존의 p-Aminobenzoic acid 생산과정을 대체할 수있을 것으로 예상된다. A facile one-pot synthesis of p-aminobenzoic acid from methyl 4-formylbenzoate which is a main by product in dimethyl terephthalateproduction process has been developed. This process involves the formation of amide intermediate obtained fromthe reaction of an aldehyde in methyl 4-formylbenzoate with chlorine in methylene chloride and the subsequent treatment ofacid chloride with ammonia. The resulting amide was converted into amine using Hofmann degradation to afford a p-aminobenzoicacid. This facile one-pot process does not involve any expensive materials and should offer an attractive alternativeto p-aminobenzoic acid production.

Purpose: The purpose of this study was to investigte perceived family support and qulakity of life in patients with cancer. Method: Data were collected from 83 cancer patients in the 3 cities of Korea. Family support was measured using the Tae's Family Support Scale and quality of life was measured using Functional Assessment of Cancer Therapy-General(FACT-G). Results: The mean scores of family support and quality of life were 30.48 and 53.04 respectively. Family support was significantly different according to marital status, education level, income, living together, helper, type of treatment, and weight change. Quality of life was significantly different according to the purpose of treatment, weight change, performance status, exercise, and sleep. There was a positive correlation between family support and quality of life(r=0.499, p<0.000). Conclusion: The study results underscore the importance of family support in improving the quality of life of patients with cancer.
