Distribution and Potential Toxicological Effects of 2,2',4,4'-tetrabromodiphenyl Ether (BDE-47) as a Endocrine Disrupting Chemical in Human and Animals

Jung, Eui-Man,Yang, Hyun,An, Beum-Soo,Lee, Geun-Shik,Hyun, Sang-Hwan,Choi, Kyung-Chul,Jeung, Eui-Bae 韓國受精卵移植學會 2011 한국동물생명공학회지 Vol.26 No.4

Polybrominated diphenyl ethers (PBDEs) are a class of "brominated" (bromine containing) man-made chemicals used as flame retardant additives in plastics, foams, and textiles. PBDEs are found in various environmental contaminants in air, soil, sediment, and water, and 209 individual forms (congeners) of PBDE exist. Among these, 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) is the dominant congener found in the environment. Exposure to BDE-47 is now worldwide, and levels of BDE-47 have been detected in the blood of animals, including humans. BDE-47 can adversely affect the developmental system in both humans and animals. BDEs have structural similarities to polychlorinated biphenyls and thyroid hormones. However, recent studies have shown that BDEs may act as hormonal disrupting chemicals with detrimental effects. Therefore, a reliable assessment of BDE-47 toxicological action is required to understand the detrimental impacts of BDE-47 on human health. In this review, we overview recent studies on the distribution and potential toxicological effects of BDE-47 in humans and animals.

Diffusion of Choline Chloride in Aqueous Solutions of Chondroitin Sulfate

Jung, Ok-Sun,Kim, Si-Joong,Kim, Hyoung-Man Korean Chemical Society 1984 Bulletin of the Korean Chemical Society Vol.5 No.6

Mutual diffusion coefficients of choline chloride were determined by using the diaphragm cell method in aqueous solutions of chondroitin sulfate A at $25^{\circ}C$. The diffusion coefficients of choline chloride in 0.1g/100ml, 0.5g/100ml and 1g/100ml respectively of chondroitin sulfate solutions were compared with those of binary systems of water-choline chloride. At low concentrations, the diffusion coefficients of the choline chloride in the presence of chondroitin sulfate were significantly smaller than the values obtained in the absence of chondroitin sulfate, indicating a strong interaction between these solutes. The effect of this interaction on the diffusion of choline ion is largest at higher chondroitin sulfate concentrations and at lower choline chloride concentrations. The influence of chondroitin sulfate is overcome at higher choline chloride concentrations. Self-diffusion coefficients of choline ion in the presence of chondroitin sulfate are also obtained. Excellent agreements were obtained between the experimental data and the calculated values obtained by using the Manning's equations. These observations suggest that the interaction between choline chloride and chondroitin sulfate involves primarily a long range electrostatic effect and there is no appreciable "condensation" or binding of choline ion to the chondroitin sulfate.

본 연구는 예비유아교사의 학업적 자기효능감과 그릿이 행복감에 어떠한 영향력을 미치는지 확인하는 데 목적이 있다. 이를 위해 부산광역시, 울산광역시, 경상남도 내에 소재하고 있는 대학교의 유아교육과에 재학 중인 예비유아교사 300명을 임의표집하여 연구대상으로 선정하였다. 예비유아교사의 학업적 자기효능감을 측정하기 위해 김아영, 박인영(2001)이 개발하고 타당화한 후 김병만, 김정주, 윤정진(2017)이 수정하여 사용한 학업적 자기효능감 검사도구를 사용하였다. 고, 그릿을 측정하기 위해 Duckworth, Peterson, Matthews와 Kelly(2007)가 개발한 Original Grit Scale(Grit-O)를 이수란(2014)이 한국실정에 맞게 번안한 척도를 사용하였으며, 행복감을 측정하기 위해 Seligman(2011)의 웰빙에 대한 PERMA 이론을 토대로 Butler와 Kern(2014)이 개발하여 김미진(2015)이 번안한 다차원적행복척도(Multidimensional Measure of Flourishing: MMF)를 사용하였다. 본 연구의 결과는 다음과 같다. 첫째, 예비유아교사의 학업적 자기효능감, 그릿, 행복감에 대한 인식에 대한 결과로 모든 변인에서 보통 이상의 긍정적인 인식 정도가 나타났다. 둘째, 예비유아교사의 학업적 자기효능감, 그릿, 행복감 간의 상관관계에는 유의미한 정적 상관관계가 있음을 알 수 있다. 셋째, 예비유아교사의 학업적 자기효능감은 예비유아교사의 행복감에 영향을 미치는 변인으로 나타났으나, 그릿은 예비유아교사의 행복감에 영향을 미치지 않는 변인으로 나타났다. The purpose of this study is to investigate the influence of pre-service early childhood teachers academic self-efficacy and grit on happiness. For this purpose, 300 Pre-service early childhood teachers in preschool education at universities located in Busan, Ulsan and Gyeongsangnam province were randomly sampled and selected. In order to measure the pre-service early childhood teachers academic self-efficacy, I used the academic self-efficacy test tool modified by Kim Byung-man, Kim Jung-ju and Youn Jung-jin (2017) after the development and validation of Kim Ae-Young and Park In-Young (2001). The original Grit Scale (Grit-O) developed by Duckworth, Peterson, Matthews and Kelly (2007) was used to measure grit. And to measure happiness, we used the multidimensional happiness scale developed by Butler and Kern (2014) and developed by Kim Mi-jin (2015) based on the PERMA theory of wellness in Seligman (2011). The results of this study are as follows. First, as a result of pre-service early childhood teachers perception of academic self-efficacy, grit, and happiness, positive perceptions were more than usual in all variables. Second, there is a significant positive correlation between the pre-service teacher s academic self-efficacy, grit, and happiness. Third, the academic self-efficacy of pre-service early childhood teachers was a factor affecting the happiness of pre-service early childhood teachers. Specifically, it was found that task difficulty preference, self-regulated efficacy, and self-confidence affect the happiness of pre-service early childhood teachers among the sub-variables of happiness. However, the sub-variables of Grit did not affect the pre-service teachers happiness.

택견 전수단체의 현황과 기예의 비교

정만영(Man-Young Jung) 한국무예학회 2007 무예연구 Vol.1 No.1

택견의 양적 팽창과는 달리 택견 전수단체 간의 갈등으로 인하여 문화재로서의 가치가 상실되고 서로간의 현실적 이해관계로 인한 갈등으로 택견의 총체적 위기를 맞고 있다. 이러한 상황을 해결하고 발전적으로 나아가기 위해서는 무형문화재의 보존과 발전적 계승이라는 모순되는 부분에서의 합일점을 찾아야만 한다.초대 예능보유자 송덕기·신한승에 대한 고찰을 통해 내재된 갈등의 미묘한 차이는 있었지만 이것이 두 보유자의 몸짓의 차이라고는 볼 수 없다. 이 후 벌어지는 단체간의 대립과 분열, 갈등의 배경과 원인을 살펴보면서 무형문화재가 필연적으로 겪게 되는 전통의 재창출 과정 속에서 현실적 이해와 결부될 수밖에 없었던 것을 알 수 있었다. 이른바 보유자 선정을 놓고 둘러 싼 1차 정체성 논쟁과 대한체육회 가맹문제에 따른 2차 정체성 논쟁으로 빚어진 것이 갈등의 배경과 원인이 된 것이다.문화재의 권위에 강하게 도전할수록 이를 견제하고 극복하기 위한 새로운 대안들이 끊임없이 생산되었기 된다. 이 또한 무형문화제도의 본질적 모순인 구심적 전승과 원심적 전승의 문제가 끊임없이 부딪치면서 발생되는 필연적 모순인 것이다. 물론 이 모든 갈등의 배경에 문화재보호법과 제도의 문제점이 도사리고 있다.본 연구에서는 발전적 전승 방안의 기준으로 이원적 전승을 제시하고 있다. 본래 택견의 전승은 여러 지역과 다양한 계층을 통해 이뤄졌다고 생각한다. 전승의 경로는 각택견의 특성과도 밀접한 관련이 있다고 생각한다. 놀이로 유희로 경기로 무예로. 체계적이고 집단적인 전승이 이뤄졌다고 볼 근거는 매우 희박하다. 따라서 전승주체에 따라 많은 변화를 보였을 것이라는 짐작도 조심스레 해본다.이런 생각을 바탕으로 각 계파의 다양성을 인정하고 그 가치를 공유해야 한다고 결론지었다. 그리고 그 하나 된 협의체인 ‘택견원’에서 현재 택견의 공통분모를 도출해 내고 그것을 각 전수단체가 공유해야 한다. Despite Taekgyeon‘s quantitative expansion, the conflict between organizations has reduced its value as a cultural heritage; the conflicting interests result in the total crisis of Taekgyeon. In order to solve such a situation, a contact must be found between the preservation of intangible cultural asset and developmental inheritance. This study, despite the logical paradox of the cultural heritage preservation law, aims to deduce a conclusion on the developmental policy of Taekgyeon.To get an answer to this question, many teaching organizations have been involved in hegemony conflicts and survival struggles regarding the cultural heritage designation. There was a sensitive difference observed in the consideration of the early cultural heritage holders Deokgi Song and Hanseung Shin, but it was not a difference in their arts. The conflict was only depicted so by the later members who brought up to the surface the conflict between the two people due to the Taekgyeon's identity struggle.Surveying the background and origin of the conflict, schism and struggle between organizations from then on, it became obvious that it was inevitable that in the process of the recreation of tradition which is common to all intangible cultural assets, realistic interests would cause a problem. The selection of heritage holder caused the first identity struggle, whereas the question of affiliating to the Korean Sports Association led to the second identity struggle.Before Gyeonghwa Jung was nominated as the heritage holder, Yongbok Lee demanded his extra nomination for GyeollonTaekgyeon as a separate heritage; when this failed, he filed a lawsuit to nullify Jung's nomination. As his stance changed from extra nomination to nullifying Jung's nomination, there was an attempt to dichotomise the difference between the arts of Shin and Song; this was to establish the identity of Song in order to distinguish himself from the heritage holder. Also, to work with the privilege of the Korean Sports Association, Lee's attempt to affiliate to the giant organization with his own Korean Taekgyeon Association failed and led to the second identity struggle.This was because new plans were produced to check and overcome challenges to the authority of the heritage. Also, the natural paradox between centripetal heritance and centrifugal heritance makes such struggle an inevitable paradox. Of course, what lies at the bottom of all trouble is the problem of heritage preservation law and system.24 years after Taekgyeon's designation as a cultural heritage, each organization lives in its own way; as they get together, modern Taekgyeon sees a new transitional period. After the sudden death of the early heritage holders which shook the Taekgyeon world, teaching organizations now slowly seek new solutions.This study proposes dualism in heritance, regarding the developmental inheritance policy. The author sees that the heritance of Taekgyeon originally occurred in various regions and various classes; and the inheritance route is closely linked to the characteristics of the art. It is difficult to see that there was a systematic and collective heritance from play to entertainment to sport to martial art. Also, it may be cautiously suggested that much change was made by the inheriting bodies.Based on this, it was concluded that each discipline must accept diversity and share its value. Also, since it is clear that such diversity, when united, would create much impact, Taekgyeon's spirit, complimentary coexistence, has been pursued. Also, the study concludes that a unitary association, namely Taekgyeonwon, should create the common denominator which may be shared by each teaching organization. Such unity in holding competitions and competing against each other would acknowledge each other's value and enable Taekgyeon and teaching organizations' development.

Case Report : Hepatoid Carcinoma of the Pancreas Combined with Neuroendocrine Carcinoma

( Ji Ye Jung ),( Yoon Jae Kim ),( Hee Man Kim ),( Hong Jeoung Kim ),( Seung Woo Park ),( Si Young Song ),( Jae Bock Chung ),( Chang Moo Kang ),( Joo Yeon Pyo ),( Woo Ick Yang ),( Seung Min Bang ) The Editorial Office of Gut and Liver 2010 Gut and Liver Vol.4 No.1

Hepatoid carcinoma is a primary extrahepatic carcinoma whose morphology, immunohistochemistry, and behavior are similar to those of hepatocellular carcinoma. The most common sites of extrahepatic carcinoma are the stomach and ovary, but nine cases of hepatocellular differentiation of the pancreas have been reported in the literature. We report another case of hepatoid carcinoma of the pancreas that was associated with the development of a pancreatic endocrine carcinoma in a 46-year-old man. Serum alpha-fetoprotein (AFP) was elevated to 262.49 IU/mL and radiological examinations revealed a mass measuring 7.5 cm in diameter in the head of the pancreas. He underwent a conventional Whipple operation, and light microscopy showed adenocarcinoma that was immunopositive for AFP, hepatocyte antigen, cytokeratin, chromogranin, synaptophysin, and alpha-1 antichymotrypsin. Although hepatoid differentiation was not shown unequivocally histologically, other immunohistochemistry findings supported the diagnosis of hepatoid carcinoma combined with neuroendocrine carcinoma. The patient was healthy and had no evidence of recurrence at 4 months after the surgery. This report describes why hepatoid carcinoma should be considered as a differential diagnosis of a pancreatic mass, especially when serum AFP is elevated. (Gut Liver 2010;4:98-102)

중고령자에 있어서 적절한 운동처방의 연구

이배익,정일호,권만근 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.14 No.4

Recently, the diet of middle aged Korean men is changing. Instead of eating Korean foods exclusively, they are consuming more Western foods which are often unhealthy. In addition, they are exercising less. These factors are leading to a rise in lifestyle related disease, such as diabetes, and dangerous medical conditions like hypertension. As a result, some middle aged men have taken up light exercise, such as hiking, walking, swimming etc. However, they don't know how to set up an exercise program, i.e. frequency of exercise, intensity, duration, etc. A 15 week exercise class was set up 36 middle aged men. Before the class began, a physical fitness and blood test were administered to each subject. The same tests were repeated after the 15th week. Based on the initial results, individual programs were prepared for each participant. A step calorie counter was supplied to measure their exercise activity. The step count results were checked everday, and based on the results, the subjects were divided into three groups for analytical purposes. The firts group, sixteen subjects(44%), averaged a little over 8,000 steps per day. The second group, eight subjects(22%), averaged between 8-10,000 steps per day. The third group, twelve subjects(33%), averaged a little over 10,000 steps per day. After fifteen weeks, the total cholesterol, HDL cholesterol and LDL cholesterol of all subjects showed no significant change. The second and third group showing an especially marked decrease in blood sugar. Also, physical fitness improved for the second and third groups. In conclusion, both groups doing the most exercise showed improvement in their TG and blood sugar results. Blood pressure also decreased for these two groups, which was not true for the first group, also, physical fitness improved in the second and third groups, while the first group showed no significant change. It appears that exceeding a certain minimum level of exercise is required to achieve good results. What would happen if group 1 did the same exercise for longer than is weeks.
