This study was performed to investigate the effects of peking-duck extracts added with medicinal herbs(DJ) on the intoxication of heavy metals (Hg, Pb, Cd, As) in rats. Sprague-Dawley rats weighing 150±15g, were randomly assigned to 5 groups: basal diet only in normal control group(NCG); basal diet and heavy metals without DJ injection in heavy metal control group(HMC); basal diet, heavy metals and DJ(3㎎/㎖) injection in heavy metal low duck juice group(HMLD), basal diet, heavy metals and DJ(30㎎/㎖) injection in heavy metal middle duck juice group(HMMlD); basal diet, heavy metal and DJ(300㎎/㎖) injection in heavy metal high duck juice group(HMHD). Hg and As was injected by 50ppm and Cd and Pb by 25ppm for 17days. Also DJ oral feeding was conducted for 28days. The result of this study were as follows: Food intake and body weight gain in heavy metal administered groups were lower than those of NCG. Liver, kidney and testis weights were not significantly different among 5 groups. GOT, GPT and BUN activities were significantly reduced in DJ treated groups as compared to HMC. DJ showed the suppressing effect on the accumulation of Hg, Pb and Cd in serum, liver and kidney. Fecal Hg and Cd excretions increased with DJ feeding. The results suggested that DJ may have some protective effects on Hg, Cd and Pb intoxication by reducing the accumulation m tissues and increasing excretion. This study also showed the effective way of using duck-extract and its application to the oriental medicine.

Sulfonated polystyrene-divinylbenzene (PS-DVB) copolymer membranes were prepared using different diluents and varying diluent volume and DVB contents. All membranes were reinforced with Teviron (PVC) cloth. Three different diluents (toluene, cyclohexane, cyclohexanol) were used in the polymerization system. The membranes have been characterized by their swelling ratio, water content, ion-exchange capacity and mechanical strength. The volume as well as kind of diluents, and DVB content influenced these properties. As a result, water content and ion-exchange capacity decreased with increasing DVB concentration. Among diluents, cyclohexanol was the most efficient for building up the highest water content and ion-exchange capacity.

정석문,김정한,김동열,육홍선,변명우,이승철 慶南大學校 附設 基礎科學硏究所 2002 硏究論文集 Vol.16 No.-

왕겨에 200, 400, 600, 800 및 1000 Gy의 저선량의 감마선을 조사하여 항산화능의 변화를 관찰하였다. 총 페놀 화합물의 양은 무처리구의 경우 0.184 mM를 나타내었고, 200 Gy로 감마선을 조사하였을 때는 0.215 mM로 약간 증가함을 보였으나 이후 차츰 감소하였다. 전자 공여능은 무처리구에 비해 처리구의 경우 조사 선량별로 조금씩의 차이만 있을 뿐, 조사 선량에 대한 왕겨의 전자 공여능은 유의적인 큰 변화 없이 비슷한 활성을 보였다. Fe^2+-ions 킬레이팅 활성은 무처리구의 경우 68.25%를 나타내었으며, 200, 400, 600 및 800 Cy 에서는 각각 86.45, 85.61, 86.65 및 82.84%로서 무처리구보다는 증가함을 보였으나, 1000 Gy에서는 74.67%로 감소하였다. 지질 과산화 억제능은 무처리구에 비해 처리구는 약간의 증가를 보였으나 효과는 미비하였다. We studied the effect of small-dose of γ-irradiation to rice hull(RH) for its antioxidant ability. The RH was treated with 200, 400, 600, 800, and 1000 Gy of γ-ray at 70 Gy/min. Total phenol amount of unirradiated RH was 0,184 mM, after irradiation at 200 Gy it increased to 0,215 mM, while irradiation above 400 Gy up to 1000 Gy decreased that to unirradiated level. The electron donating ability of RH did not show significant change depend on irradiation. The chelating ability for Fe^2+ of unirradiated RH was 68.25 %, while that of 200, 400, 600 and 800 Gy irradiated RH showed 86.45, 85.61, 86.65 and 82.84 % respectively, but, 1000 Gy was decreased to 74.67 %. According to TBARS analyses, inhibition ability of lipid peroxidation by RH was not affected by γ-irradiation.

특수교육 분야에서는 이러닝을 통하여 장애학생 교육 서비스의 양적·질적 발전을 위한 다각적인 노력을 모색하고 있다. 그러나 특수교육 현장의 실제 활용 실태와 이와 관련된 구체적인 요구에 대한 기초연구가 부족하여 효과적인 이러닝 실행을 위한 지원 방향을 수립하지 못하고 있다. 따라서 본 연구는 특수학급 교사들을 대상으로 설문조사를 실시하여 특수학급의 이러닝 관련 환경과 활용 실태를 탐색하였고, 특수학급구성원들이 가지고 있는 이러닝 실행과 관련된 요구를 밝혔으며, 이를 바탕으로 특수학급에서 이러닝을 효과적으로 운영하고 실행하기 위한 시사점을 제시하였다. E-learning is learning that utilizes contents crafted based on multimedia and hyper media via diverse information technologies. It enables teaching and learning to allow disabled students to utilize contents crafted with diverse latest techniques, thereby expanding the forum of learning. Thus, the special education area is making diverse efforts to achieve quantitative and qualitative development of educational services for disabled students through e-learning. However, since basic research is lacking with regard to the actual utilization status of e-learning and corresponding needs in special education, an appropriate support direction for performing e-learning cannot be determined. Against such a backdrop, this research surveyed the e-learning status and needs in special classes. Likewise, it surveyed the environment and utilization status of computers, software, and assistive technology that special classes in 'B' and 'D' city owned for e-learning. It also surveyed hardware and software requirements for effectively performing e-learning in special classes.

Subacute combined degeneration is a metabolic disorder of the spinal cord caused by vitamin B12 deficiency. A 72-year old man was admitted with weakness and tingling sensation of the bosh upper extremities. 9 years ago, he was diagnosed as having stomach cancer. So total gastrectomy with splenectomy was done at that time. The complete blood cell counts and morphology revealed megaloblastic anemia. Nerve conduction velocity study(NCV), electoromyography(EMG) and somatosensory evoked potentials(SEP) showed diffuse sensorimotor peripheral neuropathy. Magnetic resonance imaging(MRI) showed an increased T2-weighted signal, mild decreased T1-weighted signal, and slight contrast enhancement of the posterior columns of the cord in the cervical and upper thoracic spinal region. He was treated with vitamin B12 supplements and improved gradually. If abnormal sensation and muscle weakness was developed after gastrointestinal surgery, subacute combined degeneration should be considered in the differential diagnosis. We describe MRI findings of a typical case of subacute combined degeneration, which was induced by total gastrectomy.

The colorectal corcinoma is one of the most common malignant tumor in Korea and its carcinogenic mechanism has not been elucidated exactly yet. So far, the most common carcinogenic mechanism has been known to be multiple genetic changes. But, the CpG island hypermethylation has been revealed to be one of the most important carcinogenic mechanism second to the genetic changes. The epigenetic changes characteristically imprint and transfer to the next generation without changes of nucleotide sequences. When the CpG island of promoter or 5'- exon 1 of a specific gene is methylated by DNA methyltrasferases (DNMTs), the gene expression is inhibited. Carcinogenic mechansisms by promoter methylation has been well known, but the progression of the cancer has not been elucidated yet. The molecular researches on the carcinogenic mechanisms largely depended on the tumor tissue containing various components of cell, due to difficulties in harvesting pure homogeneous tumor cells. Promoter methylatonof the cancer related genes as APc, hMLH2, p16, DAP-K and MGMT in 50 cases of sporadic colorectal carcinoma was studied. The pure normal colorectal epithelial cells, and cancer cells from superficial and deep invasive portion were harvested respectively by laser captured microdissection(LCM), and DNA was extracted from them. The promoter methylation was studied by methylation specific poymerase reaction (MSP) after bisulfite modification of the DNA and the expression of the genes by immunohistochemistry. The results suggests that promoter methylation of the cancer related genes are closely related with the colorectal carcinogenesis and it occurrs from early phase of carcinogenesis, progressing constantly to the late stage. And the promoter methylation of normal epithelial cells increased by age. The p15, known to be the genes related to hematologic malignancy, was closely related to the colorectal carcinoma as well.

새로운 구조의 챠지펌프 방식를 사용한 직류-직류 변환기설계

한정우,손상희 청주대학교 산업과학연구소 2014 産業科學硏究 Vol.31 No.2

In this paper, output voltage conversion type of DC to DC converter using charge pump method is newly proposed and designed. In conventional cross-coupled charge pump, simulation results show that output voltage is 5.93V and efficiency is 99% and numbers of capacitor are 3 in case of step-up factor, 2. But simulation results using proposed charge pump in same condition show that output voltage is 5.96V and efficiency is 99% and numbers of capacitor are 2. From the simulation results, we know that output voltage and efficiency is similar between cross-coupled charge pump and proposed charge pump. But reducing capacitor makes chip size small and decrease cost down. In the proposed circuit, it is possible to remove the body effect secondary effective MOS by adding a body control system. It is possible to prevent that it is possible to prevent the shift in the threshold voltage of the MOS by the body controls, a result, the efficiency of the overall circuit is reduced. Also output voltage conversion is accomplished by varying the resistance ratio of the switch. Circuit simulations are executed with the design rule of magnachip 5V/30V 0.7um power-CMOS(Complementary Metal-Oxide Semiconductor) process and Cadence Spectre simulator.

필리핀 이주 기지촌 여성 ‘쥬시걸’의 민족지적 연구

한정우 이화여자대학교 한국여성연구소 : 이화여자대학교 한국여성연구원 2014 여성학논집 Vol.31 No.2

기지촌은 지금 필리핀 여성들이 과거의 ‘양공주’를 대체하고 있다. 본 연구의 목적은 참여관찰과 심층 면접을 통해 평택 주한미군 기지의 유흥업에 종사하는 외국 이주여성들의 이주의 동기와 과정 그리고 현지에서의 삶의 양식을 밝히는 민족지적 연구에 있다. 성매매 여성을 인신매매의 수동적 피해자로만 보는 시각으로부터 탈피해 한국으로의 이주 경험을 여성들의 주체적인 선택이나 삶의 전략의 하나로서 분석한다. 신자유주의 세계화 속에서 필리핀 농촌의 붕괴와 필리핀 정부의 해외 이주노동 장려 정책, 이들을 수입하는 한국 사회의 흡인 요인을 고려하면 필리핀 여성의 한국 기지촌으로의 유입은 여성의 성을 매개로 제도화된 해외이주노동에 의해 조장된다. 구조적 조건과 함께 이주과정에서의 여성의 선택의 과정을 분석하고 쥬시걸로서의 일의 과정에서 나타나는 착취적 요소와 이에 대응하는 여성의 전략을 살펴본다. 기지촌 필리핀 여성 이주자들은 본국에 송금할 수 있는 능력을 가진 노동자로서 독립적이기도 하고 의존적이기도, 기략이 풍부하기도 하고 착취당하기도 한다. 이들은 세계화의 경제 관계의 망에 갇힌, 그러나 로컬 차원의 행위자들이다. 일의 체계는 고용주가 이들을 최대로 활용하여 최대의 이득을 목적으로 하는 데서 비롯된 주스 할당량과 바 파인(bar fine)의 구조로 짜여진다. 이에 따라 계약 임금노동자로서 지급해야 하는 월급보다 성과급(주스 할당/바 파인)의 비중이 훨씬 높고, 이 부분에 계약서상에 없는 벌금이나 외출 금지의 벌칙이 적용된다. 기지촌 성산업에 유입된 필리핀 여성은 형식적으로는 외국인 계약 노동자이다. 그러나 이들이 계약을 하고 한국에 와서 일하는 모든 과정을 관철하는 하나의 본질(epiphany)은 ‘비(非)법, 편법, 합법으로 위장, 법망을 피하기’이다. 이들이 정부의 허가를 받은 외국인노동자로서 수입됐다면 입국 과정에서의 중개자 역할과 고용 과정에서의 벌금제 등 불합리한 고용 행위를 노동권에 입각해 논의하고 시정하여야 한다. The purpose of this study is to examine the experiences of Filipina entertainers at a military camp-town in Korea. It includes motivations, immigration processes, and their work in the clubs. With the ‘feminization of survival’ of the current globalization, the camp-town women have been replaced by foreign migrant women, especially from the Philippines. These women have been usually viewed as trafficked people, victims of forced sex slavery, a view that fails to recognize them as autonomous subjects. In analyzing their migration processes and lives in the clubs, I look at them not as passive agents, but rather as active ones. I have examined various structural causes as the defining factors in the Philippine women’s choices. The economic situation of the Philippines as a debtor country, along with the Philippines policy for enhancing work abroad, have led to this migration as a way of earning foreign currency. Contributing to this movement of women are the lax regulations of broker business, the efforts of the Korean camp town’s club businessmen to import foreign sex workers, a lax process of issuing entertainment visas, and lax regulations over military prostitution as a result of US-Korea relations. The women migrated to Korea to support themselves and their families back in the Philippines. Their considerations of intermarriage migration to Korea were also examined. However, their urgent financial needs have led them to reject patriarchal type marriages to Korean men. Before migration, they have access to information about their general work possibilities, but the extent and quality of this information seem to determine the conditions under which they migrate. Within the club they are struggling to expand their levels of bargaining power vis-à-vis their employers over required juice purchases and bar fines. Overall, Filipina camp-town women appear to be relieved that they are fortunate enough to migrate to Korea for higher incomes. They are independent, capable of sending money to their families, but are also dependent on labor processes which they sometimes circumvent. In order to protect them from exploitation, listening to their own voices should be the first step. To prevent abusive behaviors by brokers and club owners, there should be a system of checks and balances over labor standards, such as regular days off, lifting of the penalty system and curfews.
