Nationwide survey for angular leaf spot (ALS) of strawberry caused by Xanthomonas fragariae, aquarantine disease in Korea, was performed in November 2012. In the survey, ALS was observed ineighty eight farmers’ fields of Sukok, Jinju and Okjong, Hadong in Gyeongnam Province, and one fieldin Namwon of Jeollabuk Province. The infected field of Namwon closed immediately after the diseasediagnosed ALS. In detailed survey of Sukok and Okjong areas during February 2012 to January 2015,ALS occurrence decreased from 45% farmer’s fields on December 2012 to 5% on January 2015, andfrom 38% on November 2013 to 5% on January 2015, respectively. Phenotypic characteristics of theKorean strains were similar to those of the type strain of X. fragariae. A multilocus sequence analysisof Korean strains of X. fragariae was conducted using four genes; dnaK, fyuA, gyrB, and rpoD. All theKorean strains had the same sequences of the four genes. The concatenated sequences of the Koreanstrains shared 100% with that of the type strain of X. fragariae. All strawberry cultivars tested weresusceptible to the strains of X. fragariae two weeks after inoculation. The inoculated sites were necrosisand expanded, which were rated 4 based on evaluation of inoculation site.

Purpose: This descriptive study was conducted to identify the effects of hospital organizational culture and work environment on nurses’ intent to stay at work. Methods: Participants of this study were 234 nurses who have worked at a local general hospital in the Chungcheong province for at least 6 months. The data were collected from July 17 to 28, 2017, using self-reported questionnaires and analyzed with multiple regression using SPSS version 22.0. Results: Clinical experience (β=.38, p<.001), institutional support (β=.33, p<.001), and relation-oriented culture (β=.24, p<.001) affected intent to stay at work among nurses. These variables accounted for 34.8% of the variance in intent to stay at work among nurses. Conclusion: This study confirms the effects of the work environment and organizational culture on nurses’ intent to stay at work. Efforts for improving the work environment and organizational culture need for retaining nurses in a hospital. We suggest further research to identify the other factors associated with intent to stay at work among nurses.

Objective: The purpose of this study is to evaluate the clinical utility of adding lateral approach to conventional vertical approach for prone stereotactic vacuum-assisted breast biopsies. Materials and Methods: From April 2010 to May 2012, 130 vacuum-assisted stereotactic biopsies were attempted in 127 patients. While a vertical approach was preferred, a lateral approach was used if the vertical approach failed. The success rate of biopsies utilizing only a vertical approach was compared with that using both vertical and lateral approaches and the breast thickness for both procedures was measured and compared with that for vertical approach. In addition, pathology results were evaluated and the causes of the failed biopsies were analyzed. Results: Of the 130 cases, 127 biopsies were performed and 3 biopsies failed. The success rate of the vertical approach was 83.8% (109/130); however, when the lateral approach was also used, the success rate increased to 97.7% (127/130) (p = 0.0004). The mean breast thickness was 2.7 ± 1 cm for the lateral approach and 4 ± 1.2 cm for the vertical approach (p < 0.0001). The histopathologic results in 76 (59.8%) of the biopsies were benign, 23 (18.1%) were high-risk lesions, and 28 (22.0%) were malignant. The causes of biopsy failure were thin breasts (n = 2) and undetected difficult lesion location (n = 1). Conclusion: The addition of lateral approach to conventional vertical approach in prone stereotactic vacuum-assisted breast biopsy improved the success rate of stereotactic biopsy, especially in patients with thin breasts.

목적: 이 연구의 목적은 유방암 위험 질환의 B 모드 초음파와 탄성 초음파 (sonoelastography) 소견을 알아 보고자 하였다. 대상과 방법: 2009년 4월부터 2010년 2월까지 1390예의 초음파 유도하 생검술이 시행되었다. 이 중 수술이나 1년 이상의 추적 영상검사가 시행된 순수한 경화성 선증 13예가 이 연구에 포함되었다. 2명의 유방 전공 전문의가 후향적으로 B 모드 초음파 영상을 분석하였고 BI-RADS에따른 최종 범주를 평가하였다. 탄성 초음파 영상 소견은Itoh 등의 연구에 따른 5개의 등급으로 분류되었고, 병변과 주위 지방조직과의 변형율 비(strain ratio)가 검토되었다. 저자 등은 등급 4와 5, 그리고 변형율 비가 2.24 이상인 병변을 악성이 의심스러운 탄성 초음파 영상 소견으로간주하였다. 결과: 경화성 선증의 가장 흔한 B 모드 초음파 소견은 불규칙한형 69.2% (9 of 13) 불분명한 경계 92.3% (12 of 13), 저에코성 병변 76.9% (10 of 13)으로, 최종 범주 결과는 범주 4A, 낮은 악성 의심 소견 61.5% (8 of 13) 이가장 많았다. 가장 흔한 탄성 초음파 영상 소견은 탄성 초음파 등급 2, 42% (6 of 13)였고 2.24보다 낮은 변형율비, 69.2% (9 of 13)였다. 결론: 경화성 선증은 대부분이 악성이 의심스러운 B 모드 초음파 소견을 보였지만, 탄성 초음파 영상은 양성을 시사하는 소견을 보였다. Purpose: The purpose of this study was to evaluate the B-mode sonographic and sonoelastographic features of high risk lesions of the breast. Materials and Methods: From April 2009 to February 2010, 1390 patients with breast lesions underwent US-guided core-biopsy. Among them, 13 lesions were confirmed to be pure sclerosing adenosis by subsequent surgical excision or on imaging follow-up of more than 1 year. Two radiologists retrospectively analyzed the B-mode sonography according to the Breast Imaging Reporting and Data System classification. The sonoelastographic images were classified into 5 elasticity scores according to the Itoh classification and the strain ratio between the mass and the surrounding fat tissue was reviewed. We considered the sonoelastographic patterns to be suspicious for the case with a score of 4 and 5 and a strain ratio of more than a 2.24. Results: The common B-mode sonographic features of sclerosing adenosis were an irregular shape (69.2%, 9 of 13), an indistinct margin (92.3%, 12 of 13), hypoechogenicity (76.9%, 10 of 13) and category 4A, a low suspicion of malignancy (61.5%,8 of 13). The common sonoelastographic features were a score of 2 (42%, 6 of 13)and a strain ratio < 2.24 (69.2%, 9 of 13). Conclusion: Sclerosing adenosis showed suspicious B-mode sonographic findings,but it had benign sonolastographic features.

Using data obtained from 1, 473 adults aged 18-68 yrs, residing in large cities and by use of a semi-quantitative food frequency questionnaire, we assessed the relative importance of various foods as indicators of both the amount and the variability of selected nutrient intake to develop a simple food frequency questionnaire. Since Cronba- ch's alpha value of the questionnaire including 78 food items was 0.76, the reliability of this questionnaire was acceptable. A large fraction of the variability of nutrient intake in this population could be explained by the small number of food items. The estimation of dietary nutrient intake such as total calories or protein content, which are derived from almost all foods, will require more food items with nutrients such as calcium or vitamin A, which are concentrated in a few food items. A dietary history ascertaining the intake of as few as 5-19 food items mighted be all needed in order to determent the associa- tion between disease outcome and the intake of a single nutrient. There was certainly a high level of agreement with nutrient intake by the sbujects who were cross-classified by quartiles of nutrient indices based on all the food items(78) and by quartiles of nutrient indices based on food items selected by stepwise multiple regression for selected nutrients. The data provided further evidence that useful information on dietary intake over an extended period can be obtained by a simple and relatively inexpensive food frequency questionnaire.
