Objective: A total of five students at same middle school were reported to be diagnosed with pediatric leukemia (n=2), non-Hodgkin’s lymphoma (NHL, n=1) and aplastic anemia (n=2) between 2016 and 2017. The aims of this study are to assess exposure to environmental hazardous agents known to be associated with the risk of leukemia and to examine whether the environment of school is associated with the risk leukemia. Method: A total of 11 environmental agents causing childhood leukemia were monitored using international certified method in schools where patients had ever attended. Radon & Thoron detector was used to monitor realtime airborne radon and thoron level (Bq/m 3 ). Clinician interviewed two among nine patients who agreed to participate in this study in order to examine the association of demographic and genetic factors by individually. Leukemia, NHL, and aplastic anemia were grouped into lymphohematopoietic disorder (LHP). Results: Except for airborne radon level, no environmental agents in school and household where patients may be exposed were found to higher than recommended airborne level. Clinical investigation found no individual factors that may be associated with the risk of LHP. Higher airborne radon level than Korea EPA’s airborne radon criteria (148 Bq/m 3 ) was monitored at most of several after-class room of one elementary school, where two leukemia patients graduated. Significant radon level was not monitored at class-room. Significant exposure to radon of patients was not estimated based on time-activity pattern. Conclusions: Our results have concluded that there have been no environmental factors in school and household environment that may be associated the risk of LHP.

조선 후기 한문학과 ‘자의식의 확대’

박동욱 한국어문교육연구회 2023 어문연구(語文硏究) Vol.51 No.1

Self-consciousness is a reflective consciousness that objectifies and reflects one's thoughts and actions. Self-consciousness is a product of modernity, and it means the transition from a social existence to an individual and subjective existence. So, in the late Joseon Dynasty, the self-consciousness was expanded and strengthened as the change from ‘we’ to ‘I’, from ‘past’ to ‘present’, and from ‘society’ to ‘individual’ took place. It made me think deeply about my existence and the reason for my existence, away from following the established order and war crimes. A number of factors contributed to the awakening of self-consciousness. I thought deeply about who I was and constantly asked myself several questions and sought answers. In the process, I desperately realized that I was alone, but I also discussed the good news through solidarity with the same friends, and I also dreamed of becoming a heavenly person from the outside. While trying to get rid of 假我 and looking for 眞我, he did not stop worrying about 實幻 or 眞假. As a result, after many attempts, I recovered my true self and established a different self-image. As my perception of myself changed, there were also significant changes in literature. Rather than trying to get close to a certain war criminal in literature, he tried to raise his voice that only he could show. Changes have occurred not only in literary theory but also in literary attempts, and the change in autobiography is particularly conspicuous. The method of writing names for 居所, 字號, and 文集 was also markedly different from the previous generation. Among them, the character 號 is at the center of change. Most of the previous generations of characters were built on the basis of several principles, so there are not a lot of duplicates. However, when entering this period, not only one character was used, but several characters were used interchangeably depending on the period. In the change of self, we can read the deep contemplation of one's identity. 박동욱, 2023, 조선 후기 한문학과 ‘자의식의 확대’, 어문연구, 197 : 237~264 自意識은 자아의 생각과 행동을 객관화시켜 반성하는 성찰적 의식이다. 자의식은 근대적 산물로 사회적인 존재에서 개별적이고 주체적 존재로의 전환을 의미한다. 그래서 조선 후기에 들어서면 ‘우리’에서 ‘나’, ‘과거’에서 ‘현재’, ‘사회’에서 ‘개인’으로의 변화가 이루어지면서 자의식은 확대되고 강화되었다. 자의식의 각성에는 여러 가지 원인들이 작용했다. 내가 누구인가에 대해 치열하게 고민하고 여러 질문들을 끊임없이 스스로에게 던지고 해답을 구했다. 그 과정 속에서 혼자임을 절박하게 자각하기도 했지만 同類들과의 연대를 통해 友情論을 논하기도 했고, 외부에서 天涯知己를 꿈꾸기도 했다. 假我를 버리고 眞我를 찾으려 노력하면서 實幻이나 眞假에 대해서도 고민을 멈추지 않았다. 그 결과 여러 시도 끝에 참된 나를 회복하고 기존과는 달라진 자아상을 정립해 나갔다. 나에 대한 의식이 달라지면서 문학에 있어서도 유의미한 여러 가지 변화가 생겼다. 문학에서 어떤 전범을 설정하여 가까워지려는 노력보다는, 자신만이 보여줄 수 있는 자기 목소리 내기에 힘썼다. 문학론뿐만 아니라 문학적 시도에도 변화가 일어났으니, 自傳文學에 있어서의 변화가 특히 눈에 띈다. 居所, 字號, 文集에 대한 作名 방식에 있어서도 전대와는 확연히 달라졌다. 그중에서도 字號가 변화의 중심에 있다. 대개 전대의 字號들은 몇 개의 원칙에 입각해 지어졌기 때문에 중복되는 것들도 적지 않다. 그러나 이 시기에 들어서면 하나의 자호만이 아니라 시기에 따라 여러 개의 자호를 바꾸어 사용하곤 했다. 자호의 변화 속에서 자신의 정체성에 대한 깊은 고심을 읽을 수 있다.

Occupational Characteristics of Semiconductor Workers with Cancer and Rare Diseases Registered with a Workers' Compensation Program in Korea

박동욱,최상준,이승희,고동희,김형렬,이경희,박지훈 한국산업안전보건공단 산업안전보건연구원 2019 Safety and health at work Vol.10 No.3

Background: The aim of this study was to describe the types of diseases that developed in semiconductor workers who have registered with the KoreaWorkers’ Compensation and Welfare Service (KWCWS) and to identify potential common occupational characteristics by the type of claimed disease. Methods: A total of 55 semiconductor workers with cancer or rare diseases who claimed to the KWCWS were compared based on their work characteristics and types of claimed diseases. Leukemia, non- Hodgkin lymphoma, and aplastic anemia were grouped into lymphohematopoietic (LHP) disorder. Results: Leukemia (n = 14) and breast cancer (n = 10) were the most common complaints, followed by brain cancer (n = 6), aplastic anemia (n = 6), and non-Hodgkin lymphoma (n = 4). LHP disorders (n = 24) accounted for 43%. Sixty percent (n = 33) of registered workers (n = 55) were found to have been employed before 2000. Seventy-six percent (n = 42) of registered workers and 79% (n = 19) among the registered workers with LHP (n = 24) were found to be diagnosed at a relatively young age, 40 years. A total of 18 workers among the registered semiconductor workers were finally determined to deserve compensation for occupational disease by either the KWCWS (n = 10) or the administrative court (n = 8). Eleven fabrication workers who were compensated responded as having handled wafers smaller than eight inches in size. Eight among the 18 workers compensated (44 %) were found to have ever worked at etching operations. Conclusion: The distribution of cancer and rare diseases among registered semiconductor workers was closely related to the manufacturing era before 2005, 8 inches of wafer size handled, exposure to clean rooms of fabrication and chip assembly operations, and etching operations.

Validity of the Two-Mode Coupling Model in the Context of Cascaded Long-Period Fiber Gratings

박동욱,황준환,Park, Dong-Wook,Hwnag, Joon-Hwan The Institute of Electronics and Information Engin 2000 電子工學會論文誌-CI (Computer and Information) Vol.37 No.9

본 논문에서는 캐스케이드된 장주기 광섬유격자 구조의 해석에 기존의 두모드 결합 모델(TMCM)을 적용할 때에 발생하는 제한요인들에 대하여 분석하고, 아울러 이를 바탕으로 만족 시 TMCM 적용의 유효성을 보장하는 구체적인 조건들을 제안하다. 또한, 실제 상황에서 흔히 찾아 볼 수 있는 격자 파라메터 값을 적용하여 이와 같은 조건들이 의미하는 격자주기 변화의 허용범위와 사용가능 대역폭에 관하여 수치해석 결과를 갖고 논한다. This paper examines the constraints imposed in the usage of the conventional two-mode coupling model in the context of a cascaded long-period fiber grating and presents a set of approximate conditions that must be satisfied for the model to be applicable in the analysis of such a structure. Numerical examples based on the guidelines are provided for a set of realistic grating parameters and their practical implications on the allowed grating period variations for a given bandwidth are discussed.
