최근 저자들은 viridans streptococcus에 의한 인후농약으로 인하여 발생한 종격동염 및 농흉을 보인 47세 여자 환자를 적절한 배농과 항생제로 치료한 국내 최초의 1예를 치험하였기에 문헌 고찰과 함께 보고하는 바이다. Since the antibiotic era, retropharyngeal abscess became a rare disease entity nowadays. But it may often progress to lethal complications involving vital structure if diagnosis or treatment is delayed. We experienced a case of empyema and mediastinitis complicating retropharyngeal abscess caused by viridans streptococcus in a 47-year-old female patient with diabetes mellitus. She was successfully treated with appropriate antibiotic therapy combined with percutaneous abscess drainage. To our knowledge, such a complication of retropharyngeal abscess has not been reported in Korea yet and we present this unusual case herein followed by a review of the related literature.

Background and objectives : The warrant system is originated from concept of the due process of law guaranteed by the Constitution and the warrant is a fundamental model to guarantee all human rights. However, in the aspects of legal autopsy it has some drawbacks because of overemphasis of the formalities prescribed by law. Sometimes it hampers to find the substantial truth. Thus, the authors want to find some solutions. Materials and methods : The authors review the medical examination system for legal autopsy in Korea and China, compare them each other, and try to find some suggestions. Results : There are big differences of warrant system for legal autopsy between Korean and Chinese. Moreover there is some merits in Chinese system. Conclusion : The authors propose some alternative methods to replace the Korean warrant system for legal autopsy.

임현애,임지선,김정상 경북대학교 농업과학기술연구소 2006 慶北大農學誌 Vol.24 No.-

본 연구에서는 갈근 및 그의 주 이소플라본인 puerarin의 활성을 세포수준에서 분석하였다. 먼저 갈근에 함유된 이소플라본의 양을 분석한 결과, puerarin이 총 이소플라본의 90 % 차지하였다. 다음으로는 puerarin의 항당뇨 활성을 검정한 결과 먼저 탄수화물 및 지방소화효소저해활성에 대해서는 거의 미비한 것으로 나타났으나 인슐린 감수성 및 지방세포의 분화의 유도에 대해서는 농도의존적으로 작용하는 것으로 관찰되었다. 따라서 puerarin은 지방조직내로 포도당의흡수를 촉진함으로서 항당뇨 효능을 발휘하는 것으로 추정된다. In this study we evaluated the anti-diabetic potential of Puerariae Radix and its isoflavone (puerarin) by investigating their inhibitory activities against digestive enzymes, α-amylase, α-glucosidase and lipase and effect on glucose uptake and PPAR γ expression. The activities of carbohydrate digestive enzymes were not inhibited by puerarin. Glucose uptake in differentiated adipocytes was stimulated by puerarin. Furthermore, puerarin enhanced the differentiation of preadipocytes as evaluated by triacylglycerol (TG) accumulation, which is specific for differentiated adipocytes. The effect of puerarin on expression of peroxisome proliferator-activated receptor γ (PPAR-γ) gene, which is associated with obesity and dyslipidemia, was examined by both real-time PCR and reverse transcriptase PCR. The study demonstrated that puerarin increased the expression of PPAR-γ. In conclusion, puerarin showed potential to exert anti-diabetic action by enhancing cellular glucose uptake and thereby TG accumulation in adipocyte tissue.

Lim,Hyun-Sung,Yoon,Tae-Gyeong 한국통합사례관리학회 2021 한국케어매니지먼트연구 Vol.- No.38

This study s purpose was to examine the impact of loneliness, and two types of social support(functional and structural) on the suicidal ideation among elderly living alone. About 254 research participants were recruited from Seoul City and other cities in Gyeonggi-do and finished the questionnaires of loneliness, perceived social support, structural social support, and the suicidal ideation. Data were entered into multiple regression analyses. The finding of this research study indicates that loneliness was an important predictor for suicidal ideation. Thus, increased loneliness was associated with a high level of the suicidal ideation. This research study result showed a moderating effect of functional social support. However, structural social support did not moderate relationship between loneliness and suicidal ideation. This research study would provide implications for social work practices.

This study was performed to observe the histopathological response to the bonding resin directly applied on the remaining pulp tissuse. 40 teeth from 3 adult dogs were pulpotomized with a sterile round but and sharp excarvater. In the control group, Ca(OH)_2 powder was applied on the pulp tissue and the cavities were sealed with IRM cement. In the experimental group 1, Superbond C&B was applied on the remaining pulp and the cavities conditioned with 10-3 solution were filled with the mixture of the MMA liquid, PMMA powder and Catalyst. Multi-purpose adhesive was used on the remaining pulp tissue in the experimental group 2 and Z-100 was filled in the cavities. In the experimental group 3, Clearfil photobond applied and directly photo=cured on the pulp tissue, then the cavitieswere treated wit CA agent (10% citric acid and 20% CaCl_2 aqueous solution) for 20 seconds, washed and applied with Clearfil photobond then filled with Protect liner. The experimental animals were sacrified at the 1st, 2nd, and 4th week. The specimens were routinely processed and stained with H-E for light microscopic observation. The results were as followed : 1. In the experimental group 1, the number and characteristics of the dentin bridge formation case was similar to those in the control group and less cases were observed in the experimental group 2 and 3 than experimental group 3. The inflammatory response in experimental group 1 was less than that in the control group at 1st week but there had been little difference at between 2nd and 4th week. 2. The number of the dentin bridge in experimental group 2 was less than that in control group and experimental group 1. The inflammatory response of the experimental group 1 was similar to that of experimental group 1 but less than that of the control group. A number of bleeding and vascular congestion were observed. The least inflammatory response was seen in the experimental group 2 among all groups. 3. In the experimental group 3. one case of the dentin bridge formation was observed and that was the same as that in the experimental group 2 but smaller than that of the control and experimental group 1. The inflammatory response of the experimental group 3 was least at the 1st week and most at the 4th week in the all group.

Cutting oils denature keratin, defat the skin and remove water from it, causing dryness, fissures and frank eczematization. Solvents remove the surface lipid film. Therefore the skin barrier is weakened and the absorption of irritant substances are increased. Saturated hydrocarbons from the solvent and paraffin series are stronger irritant than those from the aromatic series. To evaluate the health effects on skin among cutting oil and solvent exposed workers, self-administrative questionnaire survey was performed on 72 exposed workers and 91 non-exposed workers. The dermatologic examination and patch test were performed on the workers with suspected skin diseases. The results are summarized as follows ; The prevalences of some dermatologic disorders, such as primary irritant dermatitis, dyshidrotic eczema, allergic contact dermatitis and folliculitis were significantly higher among exposed group than non-exposed group(P<0.05). The positive rate of patch test among 16 workers were 6.3% for cutting oil, 18.8% for old solvent, 18.8% for new solventⅠ and 6.3% for new solvent Ⅱ. These results suggest that cutting oil and solvent may be a cause of occupational dermatoses among exposed workers.

북미자유무역협정의 정치경제학: 그 성격과 성과를 중심으로

임현진,이성형,송주명 서울대학교 국제지역원 1996 국제지역연구 Vol.5 No.2

이 글은 1994년도에 출범한 북미자유무역협정의 역사적 배경에서 출발하여 협정에 이르기까지의 각국의 협상 목표와 전략, 그리고 세계경제 전반에 미치는 영향과 협정의 주요 내용, 마지막으로 지난 3년간의 공과를 간단히 검토하고 있다. 세계적 차원에서 경제적 경쟁이 심화되면서 북미 3국은 기존의 상호의존성을 토대로 자유무역지대를 창출하는데 성공하지만 각국의 목표는 조금씩 다르다. 미국은 상대적으로 경제적 이익보다는 멕시코의 안정이라는 정치적인 목료를 고려하였고, 멕시코는 발전모델의 변경에 소요되는 재워조달이라는 경제적 이유가 가장 고려되었으며, 캐나다는 반면에 불참의 불이익을 회피하기 위해 북미자유무역협정에 가입하였다. 3년간 실험 끝에 역내의 무역창출 효과는 상당히 제고되었고 산업내 무역도 활발하게 전개되고 있지만 무역분쟁은 아짇고 크게 줄지 않고 있다. 초기의 낙관론과 달리 북미자유무역협정이 미주자유무역지대로 발전할 가능성은 상당히 약하다. This study examines the historical background of the NAFTA of 1994, negotiation targets and strategies of each country involved, its impact on the world economy as a whole, and its successes and failures over the past three years. While the three North American countries succeeded in establishing a free trade area based on reciprocity in the context of deepening economic competition in the world economy, the objectives of each country in this process slightly differ each other: The United States places more emphasis on a political objective-the stabilization of Mexico; Mexico is more interested in obtaining financial resources for remolding the existing economic development model; and Canada tried to avoid the possible economic disadvantages due to the boycott. After the three year economic experiment, the effect of trade creation within the trade area and intra-industry trade have been enhanced, whereas the trade disputes among the members still remain high. But the possibility of developing the NAFTA into the AFTA seems to be modest at the moment.

海成粘土와 다짐粘土의 透水係數 豫測에 관한 硏究

It is very important for geotechnical engineers to understand properties of coefficient of permeability. The Kozeny-Carman equation is generally used at the present for estimating the coefficient of permeability. Even though the equation proposed by Kozeny-Carman gives fairly good results in estimating of sandy soils. But it is not appropriate for fine-grained soils such as clay. In the case of clayey soils, structure and distribution of particles play and important role in the coefficient of permeability. These structure and distribution are also closely related to specific surface. Large specific surface means that the grain size is very small. Soils possessing large amount of fine grains have a long flow of water. The study comes to the conclusion that the mostly related factor between specific surface and permeability appears to be #200 passing percentage in the case of compacted clays and clay content for marine clay. So new equation is proposed with the two factor in this study. But the developed equation can be used for estimating rough values in the field. That is, it is skeptical to calculate an accurate coefficient of permeability of soils. The other equations proposed until now were considered. But the results of the equations developed by plasticity index or effective grain size are far from the actual value.
