李瑯雨 대구교육대학교 1974 論文集 Vol.10 No.-

Raising crops have been so far impossible on the sandy soil of rivers. But the results obtained from this test has shown that growing crops on such soil are possible with the help of chemical fertilizer and plant growth hormone through the crops thus raised are not so good in quality and quantity as those raised on the ordinary plough land. It is expected that continuing study will bring about better effect on both quality and quantity.

한국여성의 유방암에서 estrogen수용체 및 progesterone수용체의 분포를 알아보기 위하여 39례의 유방암조직에서 이를 측정하였다. Estrogen수용체는 33.3%에서 양성으로 5.42에서 230.02f㏖/㎎ protein까지의 값을 나타내었고 progesterone수용체는 5.34내지 66.60f㏖/㎎ protein의 함량을 가진 56.4%에서 양성이었다. 폐경기 이전은 폐경기 이후에 비해 estrogen수용체와 progesterone수용체가 모두 양성인 경우가 더 많았고 모두 음성인 경우는 더 적었으며 환자의 연령이 50세 이하인 경우의 progesterone수용체 양성율은 50세 이상의 경우보다 두배 이상 높았다. 또한 액와임파절전이가 전혀없는 경우가 1개이상 전이된 경우보다 훨씬 높은 estrogen수용체 양성율을 보였으며 TNM병기 Ⅱ는 병기Ⅱ나 Ⅳ보다 estrogen수용체 및 progesterone수용체 양성율이 더 높은 것으로 나타났다. 한편 조직학적 유형과 호르몬 수용체와의 관계는 대부분이 infiltrating ductal carcinoma인 까닭에 의미 있는 결과를 얻지 못하였다. 이상의 결과에서 나타난 estrogen수용체 및 progesterone수용체와 유방암의 여러 임상적 병리조직학적 측면들과의 상관관계로 미루어 볼 때 임상검사실에서의 통상적인 호르몬수용체 측정법 확립은 유방암의 치료 및 예후판단에 매우 유용하리라 기대된다. The levels of estrogen receptors (ER) ad Progesterone receptors (PR) in 39 breast cancer tissues have been determined and a correlation of both receptor levels with the histopathologic findings and clinical features was attempted. The ER levels ranged from 0 to 230.02 fmol/㎎ cytosol protein and the PR levels ranged from 0 to 66.60 fmol/㎎ cytosol protein. 33% of the specimens were ER+ and 56% were PR+. The group younger than 50 years had a higher percentage of positive PR status. The positive rate of ER showed no significant difference between pre and postmenopause, while those of PR was decreased from 67% in pre-to 41% in postmenopause. 82% of the histologic type were infiltrating ductal carcinoma and 74% of patients were stage Ⅱ of TNM classification. These results indicated that there was strong correlation between age, menopausal status, axillary lymph node metastasis, TNM stage and receptor status.

본 연구는 생애주기별 영양지수 중 청소년을 위한 영양지수 (Nutrition Quotient for Adolescents, NQ-A) 모형을 개발하고자 수행되었다. 영양지수 평가항목 선정을 위해 식품섭취영역에서 20개 문항, 식행동·식습관 영역에서 21개 문항의 총 41개 문항으로 구성된 파일럿 조사용 체크리스트를 개발하였다. 청소년 213명을 대상으로 1일의 식사 섭취실태 조사를 포함한 파일럿 조사를 수행하고, 체크리스트 항목 점수와 식사섭취실태 관련 변수들 간의 상관관계가 높은 24개의 평가항목으로 구성된 전국단위 조사용 체크리스트를 개발하였다. 전국단위 조사는 시도별 집락별로 층화추출된 중고등학생 1,547명에 대해 구조화된 설문지로 면대면 조사를 수행하였고, 탐색적 요인분석을 수행하여 청소년 영양지수의 평가 항목을 19개 항목의 5개 요인으로 분류하고, 구조방정식 모형을 이용해 평가 항목의 구성타당도를 검증하고 추정된 경로계수를 가중치로 적용하였다. 청소년 영양지수를 위한 5개의 요인과 가중치는 각각 균형 0.25, 다양 0.15, 절제 0.25, 환경 0.15, 실천 0.20이었다. 균형 영역에는 과일 섭취 빈도, 흰 우유 섭취 빈도, 콩류 섭취 빈도, 생선 섭취 빈도의 4개 항목이 포함되었고, 다양 영역은 채소 반찬 섭취 빈도, 반찬 골고루 먹는 정도, 편식 정도의 3개 항목, 절제 영역은 과자 또는 달거나 기름진 빵 섭취 빈도, 가공 음료 섭취 빈도, 라면 섭취 빈도, 카페인 음료섭취 빈도, 야식 섭취 빈도, 길거리 음식 섭취 빈도의 6개 항목, 환경 영역은 아침식사 빈도, 식탁에 앉아서 식사하는 정도, TV·핸드폰·컴퓨터 사용 시간의 3개 항목, 그리고 실천 영역은 영양 표시 확인 정도, 음식 먹기 전 손 씻는 정도, 운동 빈도의 3개 항목이 포함되었다. 전국단위 조사대상자의 영양지수 (NQ-A) 평균 점수는 56.0점이었고, 세부 영역별로는 균형 58.6점, 다양 55.6점, 절제 48.1점, 환경 70.6점, 실천 52.1점이었다. 영양지수 점수와 각 영역별 등급은 전국 조사 결과의 백분위수 분포를 기준으로 75~100 백분위의 경우 ‘상’ 등급, 25 ~ <75 백분위의 경우 ‘중’ 등급, 0 ~ <25 백분위는 ‘하’ 등급으로 분류하였다. 영양지수의 경우 63.1~100점은 ‘상’ 등급, 49.0~63점은 ‘중’ 등급, 0~48.9점은 ‘하’ 등급으로 판정되었다. 본 연구에서 개발된 청소년을 위한 영양지수는 19개 항목으로 구성된 식행동 체크리스트를 통해 영양지수 점수와 균형, 다양, 절제, 환경, 실천 영역의 점수를 산출할 수 있으며, 상대적인 NQ 등급 부여를 통해 식사의 질과 식행동이 양호한 지를 판정할 수 있다. 본 연구에서 개발된 청소년용 영양지수 (NQ-A)가 청소년의 식사의 질과 식행동 평가 및 영양교육의 효과 평가 등에 많이 활용될 것으로 기대된다. Purpose: The purpose of this study was to develop a nutrition quotient for adolescents (NQ-A) to assess overall dietary quality and food behavior of Korean adolescents. Methods: Development of the NQ-A was undertaken in three steps: item generation, item reduction, and validation. Candidate items of the NQ-A checklist were selected based on literature reviews, results of the fifth Korea National Health and Nutrition Examination Survey data, dietary guidelines for Korean adolescents, expert in-depth interviews, and national nutrition policies and recommendations. A total of 213 middle and high school students participated in a one-day dietary record survey and responded to 41 items in the food behavior checklist. Pearson"s correlation coefficients between the responses to the checklist items along with nutritional status of the adolescents were calculated. Item reduction was performed, and 24 items were selected for the nation-wide survey. A total of 1,547 adolescents from 17 cities completed the checklist questionnaire. Exploratory factor and confirmatory factor analyses were performed to develop a final NQ-A model. Results: Nineteen items were finalized as the checklist items for the NQ-A. Checklist items were composed of five factors (balance, diversity, moderation, environment, and practice). The five-factor structure accounted for 47.2% of the total variance. Standardized path coefficients were used as weights of the items. The NQ-A and five-factor scores were calculated based on the obtained weights of the questionnaire items. Conclusion: Nutrition Quotient for adolescents (NQ-A) would be a useful instrument for evaluating dietary quality and food behavior of Korean adolescents. Further research on NQ-A is needed to reflect changes in adolescent"s food behavior and environment.

<P><B>Abstract</B></P> <P>Selective ring opening of multi-ring aromatics is a potential route for the production of valuable middle distillates from heavy oil, but a bi-functional (acidic and metallic) catalyst is required. We report here the use of mesoporous HY zeolites with variation of their mesoporosity to overcome diffusion resistance for bulky aromatics. NiW was impregnated on acidic zeolites for the metallic function of the bi-functional catalyst. To investigate the mesoporosity effect on selective ring opening, phenanthrene was selected as a model compound for multi-ring aromatics, and its reaction was conducted in a batch reactor. The introduction of moderate mesoporosity into an HY zeolite resulted in a noticeable effect on the yields of desirable mono-ring aromatics due to the easier accessibility of bulky reactants into the inner active sites of the zeolite. The mesoporosity of the catalyst seems to play an important role in the selective ring opening of phenanthrene but the optimum level should be determined.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Mesoporous HY zeolites were prepared by pseudomorphic synthesis using TMAOH and CTAB. </LI> <LI> The mesoporosity of the zeolites increased with the TMAOH concentration. </LI> <LI> Phenanthrene was selected as a model compound for multi-ring aromatics in heavy oil. </LI> <LI> NiW/mesoporous HY catalysts were used for selective ring opening of phenanthrene. </LI> <LI> The proper mesoporosity enhanced the catalytic performance due to ease accessibility. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Bacterial Contamination of Digital Panoramic Dental X-Ray Equipment

Lee-Rang Im,Ji-Hyun Min,Ki-Rim Kim 한국치위생과학회 2023 치위생과학회지 Vol.23 No.4

Background: Digital panoramic dental X-ray equipment (PDX) is frequently used by patients and dental workers for diagnosis and examination in dental institutions; however, infection control has not been properly implemented. Therefore, in this study, we aimed to systematically review the potential risk of cross-infection in the dental environment by investigating the contamination level of general aerobic bacteria and Staphylococcus aureus, which are important in hospital infections, in PDX areas that people mainly contact. Methods: This survey was conducted from March to May 2023 and covered one general hospital, three dental hospitals, and nine dental clinics equipped with PDX. Bacteria samples were collected from the left-handle, right-handle, forehead support, and head side support as the patient’s contact areas, as well as the X-ray exposure switch and left-click mouse button as the dental hygienist’s contact areas of the PDX. The collected bacteria were spread on Petrifilm, and colonies formed after 48 hours of culture were counted. Results: General aerobic bacteria and S. aureus were detected in all areas investigated. Significant differences in bacterial counts between different regions of the PDX were observed in both groups (p<0.001). The detection rates of general aerobic bacteria (p<0.001) and S. aureus (p<0.001) were significantly higher in the contact areas of patients than those of dental hygienists. A positive correlation was observed between the forehead and the temple region in terms of general aerobic bacteria and S. aureus detection (r=1) (p<0.01). Conclusion: Taken together, the presence of many bacteria, including S. aureus, detected in PDX indicates that PDX has a potential cross-infection risk. Our results therefore highlight the need for the development of appropriate disinfection protocols for reusable medical devices such as PDX and periodic infection prevention training for hospital-related workers, including dental hygienists.
