Hazardous waste is also becoming more important as opportunities for industrial waste recycling are extended. Some hazardous industrial wastes that contain many inorganic materials and heavy metals can be reused as resources: Heavy metal recovery, heat energy, etc. To facilitate the waste-to-energy system, waste generation characteristics should be defined and managed by analyzing hazardous material content. This study examines the inorganic materials (Pb, Cu, As, Hg, Cd, Cr6+, CN, Ni, Zn, F, and Ba) of industrial wastes and the generation process (case of the Korean Standard Industrial Classification) using Absolutely Hazardous (AH) Waste Lists (LoW and EU). In particular, manufacture classification was a main waste generation process (82% for “AH”). Moreover, these 10 components (Pb, Cu, As, Hg, Cd, Cr6+, CN, Ni, Zn, and F, but not Ba) are compared with the regulatory limits on heavy metals in soil: Hg and As must be under the limit of the 3 Level (0.3 ~ 7.3 mg/kg).

장미정,윤영일,권용수,윤태종,이학종,황성일,윤보라,김선미 대한영상의학회 2014 Korean Journal of Radiology Vol.15 No.4

Objective: To synthesize mesoporous silica-core-shell magnetic nanoparticles (MNPs) encapsulated by liposomes (Lipo [MNP@m-SiO2]) in order to enhance their stability, allow them to be used in any buffer solution, and to produce trastuzumabconjugated (Lipo[MNP@m-SiO2]-Her2Ab) nanoparticles to be utilized in vitro for the targeting of breast cancer. Materials and Methods: The physiochemical characteristics of Lipo[MNP@m-SiO2] were assessed in terms of size, morphological features, and in vitro safety. The multimodal imaging properties of the organic dye incorporated into Lipo[MNP@m-SiO2] were assessed with both in vitro fluorescence and MR imaging. The specific targeting ability of trastuzumab (Her2/neu antibody, Herceptin®)-conjugated Lipo[MNP@m-SiO2] for Her2/neu-positive breast cancer cells was also evaluated with fluorescence and MR imaging. Results: We obtained uniformly-sized and evenly distributed Lipo[MNP@m-SiO2] that demonstrated biological stability, while not disrupting cell viability. Her2/neu-positive breast cancer cell targeting by trastuzumab-conjugated Lipo[MNP@ m-SiO2] was observed by in vitro fluorescence and MR imaging. Conclusion: Trastuzumab-conjugated Lipo[MNP@m-SiO2] is a potential treatment tool for targeted drug delivery in Her2/neu-positive breast cancer.

한국 사회 환경교육의 발전 과정: 『환경교육』을 통해 본 사회 환경교육의 연구 동향을 중심으로

장미정,임수정,전푸름 한국환경교육학회 2019 環境 敎育 Vol.32 No.3

On the 30th anniversary of the Korean Society for Environmental Education, this study aims to identify research trends on social environmental education, to analyze different development periods and to derive insights for future studies. Out of 789 published articles (since 1989) from the Korean Journal of Environmental Education, 156 social environmental education-related articles were analyzed using the following nine criteria: year of publication, author's affiliation, research method, research topic, agent of education, educational goal, education target, place of education, and form of education. The result reveals that the number of articles that are related to social environmental education is lower than general or school environmental education-related ones. In terms of research topics, studies in educational program take up the majority whilst theoretical and philosophical research has a relatively small portion. The research trend in educational agents and location of education is found to be greatly influenced by relevant environmental education policies. Educational targets, on the other hand, have been simultaneously affected by changes in civil environmental organizations and school curriculum. In regard to the form of education criterion, non-formal education is shown as the majority. Lastly, the ratio between quantitative and qualitative study has been balanced in the recent years; the qualitative research was remarkably outnumbered in the past. Overall, it is said that social environmental education has developed with keen interactions with environmental and social changes, national/local environmental education policies as well as evolving school curriculum. In order for social environmental education to have a complementary influence in development of environmental education in the future, it is required to expand its research base to explore and interpret the diverse values of current educational activities, which take place outside of the formal institutions. 이 연구는 (사)한국환경교육학회의 창립 30주년에 즈음하여, 학회지 『환경교육』에 게재된 사회 환경교육관련 연구 동향을 파악하고, 이를 토대로 사회 환경교육의 시기별 발전 과정에 대한 고찰, 향후 연구방향에 대한 시사점을 찾는 것을 목적으로 한다. 이를 위해 1989년부터 현재까지 학회지에 게재된 789편의 논문가운데, 사회 환경교육 관련 논문 156편을 대상으로 9가지 영역별 분석(게재 연도, 저자 소속, 연구 방법 연구 주제, 교육 주체, 교육 목표, 교육 대상, 교육 장소, 교육 형식)을 수행하였다. 분석결과, 사회 환경교육 관련 논문은 일반 환경교육이나 학교 환경교육에 비해 편수가 적고, 프로그램 연구가 대다수를 차지하였으며, 이론/철학 연구가 상대적으로 낮은 비율로 나타났다. 교육 주체와 교육 장소적 특성에 따른 연구동향에서는 환경교육 정책의 영향을 크게 받고 있는 것으로 나타났고, 교육 대상과 관련해서는 민간환경단체의 변화와 학교 교육과정의 영향을 동시에 받고 있는 것으로 확인되었다. 교육 형식과 관련해서는 비형식 교육이 대다수를 차지하였다. 마지막으로 과거에는 질적 연구의 비율이 현저히 높았으나 최근에는 양적 연구의 비율도 높아져 양적, 질적 연구 편수가 비슷해진 것으로 파악되었다. 전반적으로 사회 환경교육은 환경적/사회적 변화와 함께 국가/지자체의 환경교육 정책 및 학교 교육과정 등의 정책의 변화에도 민감하게 상호작용하며 발전해온 것으로 파악된다. 향후 사회 환경교육이 환경교육의 발전 과정에서 상호보완적인 영향력을 발휘하기 위해서는 제도권 밖에서 벌어지는 역동적 교육활동의 의미를 탐색하고 해석할 수 있는 연구기반의 확대가 필요한 시점이다.

장미정,유민애,오선경,이아름,박정은 국제한국어교육학회 2021 한국어 교육 Vol.32 No.3

The purpose of this study is to present examples of e-PBL application in liberal arts writing courses for foreign undergraduates. We presented how writing classes at universities applying e-PBL were conducted for foreign students attending K University. Based on the results of the learners calculated at each stage of e-PBL, it was revealed that e-PBL lessons were feasible for foreign students. Furthermore, we were able to derive their characteristics. According to a survey of students’ satisfaction, foreign students were satisfied with e-PBL. However, e-PBL confirmed that there are space-time constraints and that it is difficult to solve the problem of reducing the satisfaction of learners such as free riders. This paper presents the direction of the course that aim to solve these problems.

장미정,김선미,윤보라,김성원,강은영,박소연,김지현,김영미,안혜신 대한자기공명의과학회 2014 Investigative Magnetic Resonance Imaging Vol.18 No.2

Purpose : The aim of this study was to determine the magnetic resonance imaging (MRI) features associated with re-excisiondue to the presence of a positive margin after breast conserving therapy (BCT) in breast cancer patients. Materials and Methods: We reviewed the records of 286 consecutive breast cancer patients who received BCT betweenJanuary 2006 and December 2007. Among 246 patients who had undergone BCT, 38 (15.4%) underwent immediatefurther surgery due to positive margin status. We analyzed the MRI findings using χ2 test, Fisher’s exact test and t tests. Multivariate logistic regression was conducted for prediction of re-excision. Results: Tumor size (p < 0.001), lesion multiplicity (p = 0.003), and non-mass-like enhancement (NMLE) type on MRI (p <0.001) were associated with margin involvement in BCT. On preoperative MRI, larger size (≥ 5 cm) (odds ratio = 2.96),NMLE (odds ratio = 3.81), and multifocal lesions (odds ratio = 2.54) were positively associated with re-excision. In casesinvolving NMLE, segmental distribution was associated with a greater likelihood of immediate re-excision. Conclusion: Larger size, multiplicity, and NMLE on MRI are significantly associated with re-excision after BCT in breastcancer patients. For NMLE lesions, the segmental distribution pattern was predictive of re-excision.

서울시 일부 아동의 식품알레르기 위험요인 : 식품 섭취와 환경적 요인을 중심으로

장미정,김규상 한국영양학회 2019 Journal of Nutrition and Health Vol.52 No.6

Purpose: This study examined the prevalence of food allergies and allergenic factors in a selected sample of children living in Seoul, Korea, along with their dietary habits, environmental factors, and diseases as risk factors for food allergy. The results of this study will provide basic data for addressing food allergies. Methods: We selected 3,004 pre-school and school-age children, aged 0 ~ 12, in the 25 districts of Seoul as the study sample. Structured self-report questionnaires were administered over a two-month period in July-August 2018, and the children’s parents recorded the answers on their children’s behalf. The research tools in this study included the Korean version of the questionnaire from the International Study of Asthma and Allergies in Childhood (ISAAC). Results: The physician-diagnosed prevalence rate of food allergies was 14.2%, while 20.4% of the children experienced allergic symptoms at least once and 17.4% reported symptoms within the previous 12 months. The children’s symptoms included skin problems (88.1%), gastrointestinal issues (19.2%), oral issues (16.7%), respiratory issues (12.7%), and systemic issues (1.3%). The causes of allergies included eggs, peaches, milk, peanuts, and shrimps. The factors influencing the experience of food allergies were the consumption of cereal (aOR, 1.52; 95% CI, 1.09 ~ 2.10; p = 0.013), potatoes (aOR, 1.88; 95% CI, 1.33 ~ 2.65; p < 0.001), and fast food (aOR, 1.73; 95% CI, 1.10 ~ 2.72; p = 0.017). Having food allergy symptoms was associated with a higher risk of experiencing asthma (aOR, 4.22 95% CI, 3.10 ~ 5.76; p < 0.001), allergic rhinitis (aOR, 2.53; 95% CI, 2.03 ~ 3.15; p < 0.001), and atopic dermatitis symptoms (aOR, 3.56; 95% CI, 2.88 ~ 4.40; p < 0.001). Conclusion: Episodes of food allergies warrant examining regular food consumption and placing dietary restrictions through early diagnosis as these episodes may imply the presence of other allergies. Our findings offer basic insights into the patterns, prevalence and symptoms of children’s food allergies in Seoul, and our findings will contribute to identifying effective interventions for food allergies.
