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.

This study was carried our to investigate the properties of thermal stratification, algal productivity, and the vertical distribution of dissolved nutrients and chlorophyll-a at Three stations of right bank in DAECHUNG Lake during the period from June to August, 1985, for the purpose of finding out the primary productivity of phytoplankton while summer stratification occurs. The following results were obtained: The stratification were showed obviously by difference of dissolved oxygen concentration water temperature, the average concentration of dissolved oxygen at hypolimnion layer was 5.7mg/1. The a average concentration of gross production at epilimnion layer was 0.70 O_2 mg/1/day in June, 0.97 O_2 mg/1/day in July, 1.30 O_2 mg/1/day in Aug, which was abruptly decreased at thermo cline layer. The average concentration of total phosphorous at hypolimnion layer was 0.059 mg/1 in June, 0.044 mg/1 in July, 0.321 mg/1 in Aug., which was over Vollenweider's eutrophic standard 0.04 mg/1. The average amount of chlorophyll-a at epilimnion layer was 9.9 mg/m^3 in June, 6.3 mg/m^3 July, 23.9 mg/m^3 in Aug. It is guessed that the growth level of phytoplankton was large. A highly significant correlation was found between total phosphorous and chlorophyll-a at the epilimnion layer (r = 0.85 p : 0.01). Therefore it could be confirmed that phosphorous was the limiting factor to algal growth.

The objective of this study is to review retrospective exposure assessment methods used in wafer fabrication operations to determine whether adverse health effects including mortality or cancer incidence are related to employment in particular work activities and to recommend an appropriate approach for retrospective exposure assessment methods for epidemiological study. The goal of retrospective exposure assessment for such studies is to assign each study subject to a workgroup in such a way that differences in exposure within the workgroups are minimized, as well as to maximize the contrasts in exposure between workgroups. To reduce the misclassification of exposure and to determine if adverse health effects including mortality or cancer incidence are related to particular work activities of wafer fabrication workers, a minimum requirement of work history information on the wafer manufacturing eras, job and department at which they were exposed should be assessed. Retrospective assessment of the task that semiconductor workers performed should be conducted to determine not only the effect of a particular job on the development of adverse health effects including mortality or cancer incidence, but also to adjust for the healthy worker effect. In order to identify specific hazardous agents that may cause adverse health effects, past exposure to a specific agent or agent matrices should also be assessed.

坯窩 金相肅의 散文 硏究 - 『坯窩遺稿』와 『重言』을 중심으로 -

Kim Sangsuk(金相肅, 1717~1792) was the writer and calligrapher. While Kim Sangsuk was noteworthy in the history of literature or calligraphy, he was mentioned only in calligraphy. In particular, there is almost no research on his proses. This paper focused on his proses around “Posthumous Works of Baewa” and “Public Opinions.” Kim Sangsuk was the writer, calligrapher and artist. As the person who was enthusiastic in writing, he had superior ability in writing. He was also interested in four treasures of study. Then, he wrote several works on them. Furthermore, he insisted that it would be required to deliberate on the opinions disparaging painting as compared to writing or calligraphy. He wanted withdrawing in the self rather than being interested in external world. His life was far from profits or wealth. He realized the negative aspects of power earlier. Thus, insights and introspection on human beings are frequently mentioned in his works. Moreover, he sincerely deliberated on the responsibilities as the intellectual. He was also interested in way of living and moral training of the intellectuals. He significantly expressed the administration awareness, the message to the society in the public world and didn’t ignore the issues on moral training and self-reflection in himself. The works related to his tendency above are mostly short compositions or short compositions with serene words. The researches on his works mainly focused on a specific group up to now. There are a number of noteworthy people when investigating his acquaintances in detail and he frequently met them. As the starting point, this research will revitalize the interest on Kim Sangsuk and his acquaintances. 본고에서는 『배와유고』와 『중언』을 중심으로 김상숙의 산문을 集中的으로 살펴보았다. 김상숙은 문인이었고 서예가였으며 화가였다. 이에 걸맞게 감식안 또한 누구 못지않았다. 또 그림에 대해서도 문장이나 서법보다 폄하하는 견해에 대한 재고가 필요하다 力說하기도 했다. 그는 외부에 대한 관심 보다는 내면에 침잠하기를 원했다. 그의 삶은 영리나 부귀와는 거리가 멀었다. 權力의 부정적인 屬性에 일찍 開眼하였다. 그래서 그의 글에는 인간에 대한 통찰과 반성이 자주 등장한다. 인간에 대한 깊은 이해가 없고는 포착하기 힘든 지점을 그는 포착해 냈다. 지식인의 處世와 修身 문제도 관심을 기울였다. 對外的으로는 대사회적인 전언, 즉 경세의식이 상당히 드러나고 있으며, 내면적으로는 修身과 自省에 대한 문제를 외면치 않았다. 김상숙이 교유했던 인물들의 면면을 살펴보면 매우 주목할 인물들도 많고 서로 간의 교류도 빈번했다. 이번 연구를 시작으로 해서 김상숙 본인은 물론이거니와 그의 주변 인물들에 대한 관심도 환기되길 기대한다.

Airborne bacteria, gram negative bacteria (GNB) and fungi were measured in 70 class of 17 kindergartens. The objective of this study is to identify the factors influencing airborne concentrations of bacteria, GNB and fungi using multiple regression analysis. The average concentrations of bacteria and fungi exceeded $1,000\;CFU/m^3$. The average of GNB was $3.7{\times}10^2\;CFU/m^3$. This results indicated that air of kindergartens was contaminated with microbes such as bacteria and fungi. ANOVA test found that the concentrations of bacteria, GNB and fungi were significantly different by the characteristics of weather (rain, after rain, sunny) sampling date (July, August, September and October), the location of sampling site (ground level and basement) and the location of toilet (inside class, nearby class and away class). Multiple regression tests concluded that sampling date, the scale of city where kindergartens are located, the location of sampling site and ventilation efficiency can significantly affect the airborne concentration of bacteria, GNB and fungi. Most of these factors could be related moisture. Environmental factors that can cause the increment of moisture should be controlled in order to reduce airborne concentration of bacteria, GNB and fungi. Legal actions concerning prohibition on the presence of toilet inside class and ventilation criteria should be taken.

Brown tumors are focal bone lesions caused by increased osteoclastic activity and fibroblastic proliferation encountered in primary, or more rarely, secondary hyperparathyroidism. Ninety-two percent of the patients who undergo dialysis develop secondary hyperparathyroidism. Of these, approximately 1.5% develops brown tumors. We recently experienced a case of brown tumor of the left maxilla that occurred in association with secondary hyperparathyroidism in a 56-year-old female. We present the clinical characteristics, radiological and pathological findings, and treatment of this rare disease entity with a literature review.
