Kim,Jung-Keun 대한구강생물학회 2007 International Journal of Oral Biology Vol.32 No.4

This study was conducted to investigate the preventingeffects of OPB (Rehmannia glutinosa Libosch and Eleuth-erococcus senticosus Max extracts) and combined OPB/Calcium therapy on bone loss in ovariectomized rats. SixtySprague Dawley rats of 12-week-old were divided into eightgroups: OVX (ovariectomized), OPBL (OPB 50mg/kg),OPBM (OPB100mg/kg), OPBH (OPB 200mg/kg), OPBL/CAL(OPBL+CAL), OPBM/CAL (OPBM+CAL), OPBH/CAL (OPBH+CAL) and CAL (Calcium citrate 88.33mg/kg+1α, 25-dihydroxy-vitamin D3 33.33IU/kg). Bone mineraldensity (BMD), bone mineral content (BMC), bone strengthindices and cortical thickness were analyzed by peripheralquantitative computerized tomography (pQCT). pQCTscanning showed that OVX induced a significant decreasein trabecular bone mineral density and bone mineralcontent in the proximal tibia (-36.4±2.4%, -21.8±12.7%).These decreases were significantly prevented by theadministration of OPBM and OPBM/CAL. Cortical BMDand BMC of tibia were slightly enhanced by OPB and OPB/CAL. However there was no significant difference betweenOVX and OPB, OPB/CAL treated group. Bone strengthindices and cortical thickness were not significantly different.Our results suggest that OPB and combined OPB/Calciumtherapy are effective in preventing the development of boneloss induced by ovariectomy in rats.

인터넷을 통한 남북통일교육에 대한 소고

2008년 현 정부 이전의 정부가 추진해 온 남북한의 화해협력정책은 교류협력의 발전을 위한 제도적 기초를 놓았고 동시에 평화위협을 제거하는 잠정적인 성과를 거두었다. 그리고 현 정부는 화해협력정책의 연장선상에서 한반도의 평화 증진과 남북의 공동번영을 통해 평화통일의 기반을 마련하는 평화번영정책을 추진하고 있다. 특히 2000년 6월과 2007년 10월 남북한 정상회담 이후 사회적 현상으로써 인터넷에 김정일을 형상화한 캐릭터가 돌아다니는 등 예전에는 상상하기 힘든일들이 대수롭지 않아지는 계기가 되었다. 당시 이러한 관심은 인터넷을 통해 다양한 형태로 나타나면서 하나의 문화 현상을 보이기도 하였다. 이제 우리는 과거 일방적인 통일에 대한 기대와 이에 따른 통일교육도 이제 새로운 전기를 마련해야 할 것으로 판단하는데, 아직까지도 우리 사회에서 통일문제에 대해 다양한 인식과 견해들이 표출되고있다.이러한 국민들의 의식을 하나로 통합하고자 통일교육의 새로운 방안으로 우리는 인터넷 활용을 적극적으로 추진할 필요가 있다. 통일교육의 새로운 방안인 인터넷의 활용은 대중이 직접 참여함으로써 프로그램 내용의 질적 변화와 방법적 변화의 효과를 가져다 줄 수 있을 것 이다. 사이버를 활용한 통일교육은 정보화 시대에 가장 적합한 교육으로 더욱 큰 효과를 가져다 줄 것으로 본다. 즉 인터넷을 통한 통일교육은 수요자 중심의 맞춤형 교육이므로 순기능적 측면을 최대한 이용 한다면 어떠한 정보 매체보다도 가장 활용도가 높고 오늘날 이 시대에 부합하는 교육방법 중의 하나일 것이다. The policy for the South-North Conciliation and Cooperation conducted since the launch of the former president Kim’s administration laid a solid foundation for the systematic development of further exchanges and cooperation between two Koreas, and yielded tangible results of eliminating threats to peace at the same time. In addition, the current Participatory Government is driving forward with the policy for peace and prosperity, which will establish a sound basis for the peaceful Unification by promoting peace and mutual prosperity on the Korean Peninsula, extended from the policy for the South-North Conciliation and Cooperation. In this regard, it is considered that a huge transition is under way for the existing Unification education of unilateral expectations for the Unification the past. Still, the Korean society is witnessing that a variety of views and opinions are emerging on the issue of Unification. It is natural, of course, that diverse opinions are shared by citizens in a free democracy. But it is surprising that there are many who question even the validity of the Unification. This paper aims to integrate people’s awareness about the Unification into unity, and carry out a new method for the Unification education, by making the best use of broadcasting and Internet. As part of new methods of the Unification education, the broadcasting media will serve as a catalyst to make qualitative and methodological changes for the education program by facilitating the direct participation by people. I understand that the web-based Unification education is the best form for education in a new era of informatization and telecommunication. As it is a customized education devoted for users, it is my view that it will be the most appropriate educational method with the highest level of exploitation rather than any other information media.

Nonpoint source pollution(NSP) arises due to agriculture activity and it is quite an extensive and complicated problem in order to control and has received a great deal of concern during the recent years, whereas point source are known to originate from an estimated volume of contaminant discharged from a distinguishable source. Extensive research work have been conducted and presented in the past with regard to the various characteristics of watershed on Dong Jin River(DJR), however there are certain drawbacks of existing survey for determining important polluting sources, distribution features of pollutants and estimated load of the organic and nutrients from the creeks. Unfortunately, investigation for loadings originating due to agricultural drainage was not satisfactory, although the regional consideration for DJR across Kim Je Field(KJF) as an agricultural area receives a reasonable source point in the agri-pollution management. Therefore it was necessary to carry out a thorough investigation into the diffuse sources resulting, to form the pollution-developing estimation and to evaluate the output roperties and determining various factors in the generation of non-point pollution. Eventually, this research work would serve as an useful tool for the development of predictive pollution management for DJR. Non-point sources in the present work were classified as municipal non-treated sewage water discharged into the river, loadings through agricultural drainages in the dry/wet field and inadequate treatment of wastewater generated from livestocks. The entire duration of the research work was from December-2001 to July-2002. Site measurement were conducted during various season, in a dry season(December), in rainfall, in seed-sowing time and also collecting data from the rural public organizations related to water management was done and examined and examined during the mid of research work. Similarly, domestic wastewater loadings due to population was based on area unit, as City, Country, Up, Myon, Dong, Ri. The Dong Jin River watershed contains small three Creeks, KoBu(KB), DongJin(DJ, including JeongEup(JE) and ChilBo(CB), WonPyong(WP). It was further divided into 32 sub-watersheds which comprises of further 5,18,9 watersheds in the creeks respectively. The results obtained from research work are presented as follows. Animal productions have marked differences in the rate of pollutant loadings reported in the following sequence: DJ(only CE)>WP>CB>KB, in a case of Korean cow and milk cow. However, it was revealed that WP creek became significantly higher than any other livestocks. According to statistical data for land use, rice field(369.0㎢) and forest(378㎢) have much occupation prior to dry paddies(125.0㎢), residential land(32.0㎢) and others(5.0㎢). Especially, rice fields receives 2.5∼3 times than dry paddies in size.

고진공내의 데칸용매하에서의 요오드화 iso-프로필의 용해도를 8, 15, 25℃에서 니트로벤젠과 톨루엔이 존재할 때와 존재하지 않을 때의 두 경우에 대하여 각각 측정하였다. 데칸용매내에 니트로벤젠과 톨루엔이 존재할 때 요오드화 iso-프로필의 용해도가 존재하지 않을 때 보다 더 크고, 톨루엔과 요오드화 iso-프로필과의 상호작용이 니트로벤젠과의 상호작용보다 더 강하게 작용한다는 것을 알 수 있었다. 그리고 니트로벤젠과 톨루엔이 데칸용매내에 존재할 때 요오드화 iso-프로필과 니트로벤젠 및 톨루엔이 각각 불안정한 Complex를 형성한다고 생각되어 이 Complex를 여러 경우의 비율로 가정하여 계산해 본 결과 1 : 1 Comples를 형성한다고 보는 경우의 평형상수 K값이 비교적 일정한 값을 나타내었다. 그러므로 1 : 1 Complex 즉 ??과 ??이 용매속에 형성됨을 알았다. 또한 이 Complex의 생성에 대한 엔탈피, 자유에너지 및 엔트로피의 변화도 산출하였다. The solubilities of iso-propyliodide in decane on high vacuum were measured at 8℃, 15℃ and 25℃ in the presence and absence of nitrobenzene and toluene. When nitrobenzene and toluene exist in system respectively, the solubilities of iso-propyliodide in the presence of nitrobenzene and toluene are greater than in the absence, and the interaction of iso-propyl iodide with toluene is stronger than with nitrobenzene. In the presence of nitrobenzene and toluene, it could be thought that iso-propyl iodide forms unstable complex with nitrobenzene and toluene. The complex was assumed in various ways and it was evaluated that the equilibrium constant K value was relatively constant under the assumption of 1 : 1 complex. Thus, 1 : 1 complexes, ??과 and ?? are formed in the solution. Also, the changes of enthalpy, free energy and entropy for the formation of the complex were calculated.

Objectives : The purpose of this study was to evaluate the characteristics of psychopathology, adverse drug effects, and Subjective response to drugs that have a significant impact on the subjective quality of life in schizophrenic patients receiving atypical antipsychotics. Methods : One hundred and one schizophrenic patients, who were receiving maintenance treatment with atypical antipsychotics, were evaluated. Subjective quality of life was assessed using the standardized Korean modification of a self-rating scale to measure subjective well-being under neuroleptics (KmSWN). Patients' psychopathology was evaluated using the Positive and Negative Syndrome Scale. Adverse effects and subjective response to drug were evaluated using the Liverpool University Neuroleptic Side Effect Rating Scale and the Drug Attitude Inventory-10, respectively. Correlation analysis and stepwise multiple regression analysis were conducted. Results : In psychopathology, the severity of depression and anxiety showed the most significant correlation with the score ofKmSWN. In adverse drug effects, the severity of psychic side effect and extrapyramidal side effect showed the most significant correlation with the score ofKmSWN. Regarding subjective response to drug, significant correlation was observed between the severity of subjective negative response and the score of KmSWN. Stepwise multiple regression analysis revealed that psychic side effect, extrapyramidal side effect, and depression contributed significantly to the total score of KmSWN. These variables accounted for 59.7% of the total variance. Conclusion : The results of the present study suggest that psychic side effect, extrapyramidal side effect and depressive symptom are the clinical characteristics that are significantly associated with the subjective quality of life. An effective management strategy for these variables should be established in developing a treatment program to enhance the quality of life of patients with schizophrenia.

평택시에 위치한 펄프 회사에서 탱크 내부를 청소하고자 근로자가 탱크 속으로 들어가는 도중 의식을 잃었다. 펄프제지 과정에서 유기물질의 발효로 인하여 유해한 가스가 발생한다. 발생할 수 있는 가스의 종류에는 이산화탄소(CO₂), 일산화탄소(CO), 암모니아(NH₃), 황화수소(H₂S) 그리고 메틸 머캅탄(methyl mercaptans, CH₃SH) 등이 있다. 작업환경 측정전 이러한 가스들이 존재할 것으로 추정하였으나 실제적으로 황화수소와 일산화탄소만 검출되었을 뿐 암모니아와 메틸 머캅탄은 측정되지 않았다. 그런데 상기 환자들에 있어서 HbCO이 정상 범주이므로 일산화탄소의 중독은 배제할 수 있었다. 따라서 황화수소 중독에 의한 의식소실임을 알 수 있었다. Hydrogen sulfide poisoning is frequently encountered in the workplace. Two workers lost their consciousness In an underground tank at a factory producing paper. The tank contained liquid mixture of used paper, sodium oxygenate chloride (NaOCl), and sodium thiosulfate pentahydrate(Na₂S₂O₃.□H₂O). A worker(worker A; 36-year-old man) entered tank to remove sludge. When worker A lost his consciousness, worker B entered the tank to rescue worker A, however he lost consciousness inside the tank. We discuss in detail the clinical features of this condition. Hydrogen sulfide poisonings have occurred in industries involving petroleum refining, the manufacture of heavy water, tanning of hides, vulcanization of rubber, and the manufacture of rayon. And it is necessary to stress the health education for workers and managers in these industries.

The working time of dental cement has a close relation with the setting time, where the setting reaction can be said as the result of the chemical reaction between cement liquid and powder. The purpose of this experiment was to investigate the setting characteristics and setting rate of dental cements by measuring the exothermic heat(Joule/gram) from the setting reaction at specified times using a differential scanning calorimeter (Differential Scanning Calorimeter, DSC 204, TASC 414/3A Controller, Netzche, Germany). Graphs of time-exothermic heat at 37℃ isothermal condition, showing the setting reaction of dental cements were plotted. Three types of luting cements studied were zinc-phosphate cement (ZPC), polycarboxylate cement (PCC), and glass ionomer cement (GIC). The effects of powder-liquid ratio on the setting characteristics of cements were also included. The amount of heat (calory) released per one gram of cement was calculated at each specified time, and was analyzed. ANOVA and Scheff's multiple comparison test (p=0.05) were used for statistical analysis using SPSS/PC+. The setting rate of cement was not constant during the setting reaction, and different setting characteristics were observed depending on the type of cement and powder/liquid ratio. Generally, 70∼90% of the setting reaction, measured by the exothermic heat release, occurred within 5 minutes after mixing. The exothermic heat released by ZPC was very high immediately after mixing, and the duration of the heat release was prolonged compared with other cements. The exothermic heat release of PCC finished most rapidly. It was generally observed that the amount of heat release (rise in temperature) per one gram of cement was highest for ZPC, followed by GIC, and then PCC. However, heat release during the first 2∼5 minutes after mixing was highest for GIC, followed by ZPC and then PCC. According to the Scheff's multiple comparison test, the duration of the total setting reaction did not show any significant difference among the cements(p>0.05), and also among the different power/liquid ratio groups(p>0.05). It was observed that more heat was released with the lower powder/liquid ratio than the higher powder/liquid ratio.
