The purpose of this study is to observe the brain activity patterns during visual oddball tasks with two difficulty levels by the analysis of high-density event-related potential (ERP). Along with conventional statistical analysis of averaged ERP waveforms, we applied independent component analysis (ICA) for the individual, single-trial analysis and verified its effectiveness. We could identify multiple ERP components such as early visual components (P1, N1), and two components which seem to be important task-related components and showed difficulty-dependent variability (P2, P300). The P2 was found around central region at $180{\sim}220ms$, and the P300 was found globally at $300{\sim}500ms$ poststimulus. As the task became difficult, the P2 amplitude increased, and the P300 amplitude decreased. After single-trial ERPs were decomposed into multiple independent components (ICs), several ICs resulting from P2 and P300 sources were identified. These ICs were projected onto scalp electrodes and the projected ICs were statistically compared according to two task difficulties. For most subjects, the results obtained from single-trial/individual analysis using ICA gave the tendencies of amplitude change that are similar to the averaged ERP analysis for most subjects. The temporal pattern and number of ICs corresponding to ${\mu}$ rhythm was not dependent on the task difficulty. It seems that the motor response was not affected by the task difficulty.

Objectives: Alongside smoking, occupational exposure is an important risk factor for chronic obstructive pulmonary disease. The purpose of this study was to evaluate factors associated with occupational pulmonary function decline that can be used to create guidelines for the health management of shipyard workers Materials: This study analyzed spirometry from 10,597 male shipbuilding workers. Functional decline in spirometry was defined as FEV1/FVC <70% and logistic regression for work duration and occupational hazard exposure was performed Results: Among the subjects, 4.2% showed an obstructive pattern in pulmonary function. The odds ratios for hazard exposure were 1.67(indirect) and 3.54(direct), and for work duration 1.97(10-18 years), 2.29(19-27), and 5.02(28+). After adjusting for smoking and work-related factors, the odds ratios for work durations of over 10 years were 1.73(10-18 years), 1.99(19-27), and 4.09(28+), but for hazards exposure was 1.71(direct) alone after adjustment. Conclusions: Occupational COPD is insidious and chronic, and thus long-term hazard exposed(especially over 10 years) shipyard workers with functional decline in spirometry need to prevent and manage COPD. This study is important for establishing guidelines to manage hazard exposure among shipyard workers and prevent COPD

Objectives: The objective of this study was to identify the relationship between fish consumption and blood mercury levels in a sample of adult Koreans. Methods: The study subjects were 299 residents of Busan (male: 65, female: 234) and 185 residents of Namhae (male: 69, female: 116), South Korea. Demographic characteristics, current smoking, current drinking, fish consumption per week, past history of amalgam treatment, and residential district were recorded by trained interviewers in June and July, 2009. We considered a portion of fish to be equivalent to 70 gm weight, and calculated amounts of fish consumed per week. Using chi-square tests, t-tests, ANOVA, and multiple linear regression analysis, we estimated the relationships between blood mercury levels and amount of fish consumed per week and other factors. Results: The mean blood mercury level of our subjects was 6.61 ${\mu}g/L$, higher than the criterion defined by the United States Environmental Protection Agency (EPA) (5.8 ${\mu}g/L$). In multiple linear regression analysis, residential district and amount of fish consumed per week were associated with blood mercury levels. However, marital status, current drinking, and gender, and age were not associated with blood mercury levels. Conclusions: In conclusion, we suggest the implementation of systematic and periodic population-based studies to decrease the risks of mercury poisoning among South Koreans who consume fish as a regular part of the diet. 본 연구는 직업적으로 수은에 노출되지 않는 일반 인구 군에서 생선 섭취량과 혈중 수은 농도 사이의 관련성을 파악하기 위하여 수행되었다. 이를 위하여 부산광역시 2개 동과 남해군 3개 마을에 거주하는 사람들 중 본 연구 참여에 동의한 484(남자: 134명, 여자: 350명)명을 최종 연구대상으로 하였다. 설문조사는 2009년 6월 말부터 7월초까지 연구 참여 희망자들을 대상으로 훈련된 조사자가 면접설문조사를 실시하였다. 설문 조사의 주요 내용은 성별, 연령, 학력, 결혼상태, 직업, 현재 흡연 여부, 현재 음주 여부, 일주일간 생선 섭취량, 아말감 치료, 거주지역 등이었다. 단변량 분석에서 성별, 나이, 결혼상태, 현재 음주 여부, 일주일간의 생선 섭취량, 그리고 거주지역이 혈중 수은 농도와 유의한 관련성이 있었다. 혈중 수은 농도를 종속 변수로 한 다중선형회귀분석에서 일주일간의 생선 섭취량, 그리고 거주지역이 혈중 수은 농도와 유의한 관련성이 있었다. 생선 섭취량과 혈중 수은 농도 간에는 통계적으로 유의한 관련성이 있다. 앞으로 혈중 수은 농도와 건강 장애간의 관련성을 비롯한 추가적인 연구를 통하여 생선 섭취와 연관된 수은 노출 기준, 실제적인 생선 내 수은 잔류 기준, 생선 섭취빈도와 생선 섭취량에 관한 여러 가지 권고안들을 마련하기 위한 근거 기반을 마련해야 할 것이다.

학교 과학실험활동의 역할에 대한 초등학교 교사들의 인식

김자현 ( Kim Ja-hyeun ),김효남 ( Kim Hyo-nam ),양일호 ( Yang Il-ho ) 부산대학교 과학교육연구소 2020 교사교육연구 Vol.59 No.1

이 연구의 목적은 문헌연구를 통해 도출한 학교 과학실험활동의 역할에 대해 초등학교 교사가 가지고 있는 실제 인식을 분석하여 교사의 인식 실태를 파악하는 것이다. 이를 위해 면담지를 개발하고, 초등학교 교사를 대상으로 면담 자료를 수집한 후 분석하였다. 면담은 부산광역시 소재 공립 초등학교에서 2018년도에 과학 교과를 지도하는 교사 9명을 대상으로 진행하였다. 연구 결과는 다음과 같다. 첫째, 학교 과학실험활동의 역할 전반에 대한 초등학교 교사의 보편적 인식을 분석한 결과, 초등학교 교사들은 주로 학교 과학실험활동의 역할 중 ‘과학에 대한 태도 증진,’ ‘과학적 탐구 방법 학습’ 역할을 중요하다고 인식하였고, 이에 비해 ‘과학의 본성 이해’ 역할은 이해도가 낮아 중요하지 않다고 인식하였다. 둘째, 실제 실험활동 사례에서의 과학실험활동의 역할에 대한 초등학교 교사의 실천적 인식을 분석한 결과, 초등학교 교사들은 주로 실험활동에 따라 적절한 학교 과학실험활동의 역할을 선택해야 하며, 자신이 선택한 역할을 학생들에게 안내할 필요가 있다고 인식하였다. 또한 사례를 확인하는 과정에서 특정 실험수업 상황에 따라 어떤 역할을 중점으로 두는 것이 의미가 있는지를 구체적으로 인식하였다. 그리고 학교 과학실험활동의 역할을 잘 고려하여 지도하기 위해서는 교사의 소양이 중요함을 인식하였다. 직전과 직후 교사교육을 할 때 과학실험활동의 역할과 그에 대한 교사들의 인식과 같은 새로운 연구결과를 반영하여야 한다. 시대가 변함에 따라 중점적으로 추구하여야 할 과학교육의 목표도 변하고, 이에 따라 교사교육내용과 방법도 달라져야 할 것이다. The purpose of this study was to analyze the actual cognitions of elementary school teachers about the rank of role of science practical work at school derived through literature review. For this purpose, an interview questionnaire was developed and interview data were collected and analyzed for elementary school teachers. The interviews were conducted with nine teachers who taught science in 2018 at public elementary schools in Pusan. The results of the study were as follows. First, elementary school teachers were well aware of two roles, enhancing of attitude toward science and learning of scientific inquiry methods, but were not fully aware of understanding of the nature of science. Second, elementary school teachers usually recognized that they had to choose the appropriate role of science practical work at school in accordance with science practical work, and that they need to guide students to know the chosen role. Specifically, they recognized which role is meaningful according to science practical work situations. In addition, they recognized that teacher's understanding the role of science practical work is important. Teacher education should consider teacher’s recognition about the role of science practical work. According to passing the time science education objectives are changed. Therefore the contents and the methods of teacher education should be refreshed and changed.

조선 후기 『화엄소초』의 한국 유전과 불교미술의 제작 양상

김자현(Kim, Ja-Hyun) 동국대학교 불교문화연구원 2023 佛敎學報 Vol.- No.102

18세기 조선에서는 1681년 우연한 기회로 전래된 가흥대장경을 계기로 화엄 교학의 중흥이 일어났다. 그 중 澄觀의 『화엄소초』와 普瑞의 『화엄현담회현기』와 같은 화엄 관련 불전의 전래는 조선 후기 불교 교학의 일대 전기가 되었고, 이 불전들이 복각되어 강원 교재로 사용되면서 화엄학이 본격적으로 유행하게 되었다. 그리고 화엄을 우위에 두면서도 다른 교학과 禪을 포섭하고 유교, 도교와 같은 중국적 사유와 불교를 회통하고자 했던 징관의 제교융합적 화엄은 고려 후기부터 점차 선교겸수의 경향을 강화시켰고, 조선후기에 이르러 선, 교, 염불의 삼문체계의 정립과 간화선과 화엄이 양립하는 선교겸수의 구조에 지대한 영향을 미쳤다. 또한 이 시기 화엄학의 성행은 신앙과 사찰의 장엄에도 영향을 미쳐 화엄 교학이 반영된 새로운 미술품들이 제작되었다. 이 시기에 그려진 <화엄경변상도>와 <연화장세계도>는 화엄경의 구조와 화엄의 연화장세계를 시각적으로 구현한 대표적인 화엄계 불화이다. 또한 화엄신중신앙의 반영으로 이전까지 단독이나 불화의 구성 요소로 표현되던 호법신들이 화면에 군집을 이룬 구성으로서 하나의 독립된 畵目으로 전각에 봉안되기 시작한 <신중도>, 과거 53불의 53이라는 숫자와 『화엄경』 「입법계품」에 등장하는 선지식의 法數를 매개로 화엄과 多佛신앙을 융합한 사례도 조선 후기에 나타난 독특한 양상이다. In the eighteenth-century, Joseon, a fortuitous introduction of the Jiaxing Dazangjing (嘉興大藏經, K. Gaheung Daejanggyeong) in the country led to the revival of the Hwaeom (Ch. Huayan) doctrine. In particular, the transmission of Chinese Huayan sutras such as Chengguan 澄觀s Huayanshuchao (華嚴疏鈔, K. Hwaeom Socho) and Pureuis 普瑞 Huayanxiantanhuixuanji (華嚴懸談會⽞記, K. Hwaeom Hyeondam Hoihyeongi) laid a significant foundation for Buddhist studies in the late Joseon dynasty. These sutras have been reproduced and used as textbooks, leading to the widespread popularity of Hwaeom studies. Chengguans Huayan theory that sought to embrace Chan (禪, K. Seon) and other Buddhist doctrines and harmonize Buddhism with Confucianism, Taoism, and other Chinese philosophies, promoted the simultaneous practice of both Seon 禪 and Gyo 敎 (Doctrinal Buddhism) in the late Goryeo dynasty. In the late Joseon dynasty, his theory greatly influenced the establishment of the Discipline of the Three Gates of Seon, Gyo, and Yeombul 念佛, as well as the simultaneous practice of Seon and Gyo, which sought the coexistence of Ganhwaseon 看話禪 and Hwaeom 華嚴. The flourishing of the Hwaeom doctrine in Joseon during this period had a profound impact on devotees’ faith and decoration of Buddhist temples. This led to the creation of new types of Buddhist artworks reflecting the Hwaeom doctrine, and representative examples from this period include the Illustrated painting of the Avatamsaka Sutra 華嚴經變相圖 and the World of Lotus Flowers 華藏世界圖, which are visual representations of the structure of the Avatamsaka Sutra and the World of Lotus Flowers. In addition, starting from the eighteenth century, as a reflection of the worship of Hwaeom deities, Sinjung-do 神衆圖, painting of a gathering of numerous Buddhist deities guarding the Buddhist Dharma, was enshrined as an independent subject of Buddhist art inside the hall of a Buddhist temple. This period also witnessed a unique combination of the Hwaeom doctrine and the belief in many Buddhas, promoted by the coincidence of the number 53 symbolizing the 53 Buddhas of the past and the number of Dharmas (53 teachings by 53 teachers) appearing in the chapter “Entry into the Realm of Truth 入法界品” of the Avatamsaka Sutra.

조선시대『佛說阿彌陀經』變相版畵의 도상연구

김자현(Kim Ja Hyun) 동국대학교 박물관 2015 佛敎美術 Vol.26 No.-

Regardless of the times, people have constantly desired to go to (Amita) pure land after death, and this popularity of Amita faith has brought a number of transformation paintings to be produced and reproduced. In this sense, the transformation painting of Amitabha-sutra provide some insight into the Amita faith of that time and are also an important field of study in examining iconography included in the paintings. A total of 29 woodcut prints related to Amitabha-sutra are passed on and known to be published in Joseon, among which, 13 woodcut prints contain transformation paintings and were produced in the late 16th century. The transformation prints of Amitabha-sutra of Joseon are classified into two different types based on how the paintings are placed inside the book: one is putting paintings and texts together; the other is placing paintings only at the beginning of the book. The iconography included in the paintings can be examined based on the scriptures. The transformation prints of Amitabha-sutra of Joseon belong to the first type and have paintings on the upper part and texts on the lower part. This type of prints is 5 in total, and it either copied or revised the image painted on the book published in 1572 in Deokju temple. Such prints also have 26 (transformed) scenes engraved, except for the one published in Yongchun temple which adds Yongsunjubindo (龍船接引圖) onto 18 to 24 sheets of printing blocks. This type of print of Amitabha-sutra was produced in Ming of China as well. However, they are different in details of the image and in the way of writing the accompanying inscriptions. This suggests that China may have produced the prints which have paintings at the top and the texts at the bottom, apart from (the type of) the Chinese prints existing today. There are 8 transformation prints of Amitabha-sutra which place paintings at the beginning of a book. This number includes transformation prints of Amitabha-sutra and related scriptures such as Bulsul-Amitabha-sutra-yohae(佛說阿彌陀經要解) and Dae-Amitabha-sutra (大阿彌陀經). Unlike the type of prints mentioned earlier, this type of prints is composed of many different images, except for the reprinted editions of the book published in Duck temple (1871) in the 20th century. For this type of prints, key images are selected from the type of the transformation prints described above, and some images are adopted from other transformation prints of the Lotus Sutra and Amitayurdhyana Sutra. A good example is the transformation prints included in Dae-Amitabha-sutra (大阿彌陀經), which is Amita-related scriptures published in Bokwang Temple in 1881. They consist of paintings printed in 2 sheets of printing blocks - Painting of Sakyamuni's Preaching and a memorial tablet printed on one side and Painting of Amita Pure Land printed on the other. They can find their origin in the transformation prints of Sakyamuni Platform Painting published in Qing and the transformation prints of Amita Pure Land published in Ming, both of which exist today. Therefore, there is a need to conduct more in-depth studies on such combination of iconography.
