저자 등은 기존의 치료에 반응하지 않은 중증 허혈성 지체질환 환자를 대상으로 하여 vascular endothelial growth factor를 이용한 혈관신생 유전자 치료를 시행하였다. 치료 후 환자의 허혈에 의한 하지 통증이 현격하게 감소하고 상처의 진행이 측부혈관이 많이 증가됨이 관찰되어 이에 문헌고찰과 함께 보고하는 바이다. We report VEGF-induced angiogenic gene therapy in a patient with critical limb ischemia, who did not respond to conventional treatment. This patient was the first case in a dose-escalating series of phase I clinical trial. The patient had severe resting pain, gangrene and diffuse ulcer in his left foot. Total 1,000㎍ of naked DNA encoding human VEGF165 was administered intramuscularly to 8 sites of the loft lower extremity. Four weeks after the first 1,000㎛ was administered to the same sites (total dose: 2,000㎛). After gene therapy, resting pain gradually reduced and the amount of analgesics taken by the patient decreased. The ischemic wound of lower extremity slightly improved. However, there was no complete wound healing at 12 weeks of treatment. Digital subtraction angiography at 12 weeks after gene therapy showed an increase in collateral vessels at the mid-tibial, ankle and foot arch levels. Immediately and up to 12 weeks, there was no complication related to gene therapy. These findings may be cautiously interpreted to indicate that intramuscular injection of naked plasmid DNA of VEGF_165 may induce therapeutic angiogencsis in a patient with critical limb ischemia. Further clinical evaluation of VEGF-induced gene therapy is needed to evaluate the safety and efficiency of this treatment.(Korean J Med 64:85-90, 2003)

Objective. Productivity loss was compared by 3-stage of disease activity and associations between higher disease activity and high productivity loss were identified. Methods. Data were extracted from Rheumatoid Arthritis (RA) Patient-reported Outcomes Research, which enrolled 2,000 RA patients (>20-year) on disease-modifying-antirheumatic-drugs (DMARDs) (≥ 6-month) from December 2012 to June 2013. This included 1,457 RA patients with the disease activity score (DAS-28-ESR) in their medical charts. Productivity loss in time and indirect cost was estimated using The World Health Organization Health and Work Performance Questionnaire (HPQ). Baseline characteristics and productivity loss outcomes were compared according to DAS-28-ESR groups. Results. 84.4% were females, 54.2% had low DAS-28-ESR (<3.2), and 38.2% and 7.6% had moderate (3.2∼5.1) and high DAS-28-ESR (>5.1). Patients with moderate to high DAS-28-ESR had higher lost productivity time (LPT) and monthly costs of LPT than those with low DAS-28-ESR (time in hours: 110.0±58.4 vs. 132.4±57.2 vs. 71.5±52.0, p<0.0001; monthly costs of LPT in 1,000 Korean won: 1,097±607 vs. 1,302±554 vs. 741±531, p<0.0001). Multiple regression analyses revealed significant associations with high LPT in high (adjusted odds ratio [OR]=3.87, 95% confidence interval [CI]: 2.18∼6.87) and moderate DAS-28-ESR (adjusted OR=1.88, 95% CI: 1.41∼2.52) compared to low DAS-28-ESR. In addition, positive associations with high monthly costs of LPT were observed in high (adjusted OR=3.45, 95% CI: 1.98∼5.99) and moderate DAS-28-ESR (adjusted OR=1.93, 95% CI: 1.43∼2.54) compared to low DAS-28-ESR. Conclusion. Timely therapeutic strategies should be taken into consideration given that the RA patients with moderate to high DAS-28-ESR showed strong associations with high productivity loss for effective management of RA.

대형 프로젝트 수주를 위해서는 기획·관리능력뿐만 아니라 건설업체의 금융조달능력이 필요하다. 프로젝트 파이낸싱은 단일금융기법이 아닌 복합적이고, 다양한 이해당사자가 관련된 자금조달기법이므로 그 관계당사자중 한 부분의 노력만으로는 성공할 수는 없다. 정부와 금융기관이 협조를 강화하고, 특히 정부차원에서 지원정책과 규제 완화조치로 지원을 개선하는 노력이 필요하다. 이에 국내 건설업체도 프로젝트 파이낸싱의 도입을 건설 수주를 위한 하나의 수단으로만 받아들이는 오류를 피하고 국내외 건설환경을 분석·대응하는 등의 적절한 대처가 요구되며, 기술경쟁력뿐만 아니라 건설관리능력과 자금조달에 관련하여 프로젝트 파이낸싱의 필요성을 인식하고 연구하여 활용하도록 해야 한다. Receiving a major project order requires not only planning and management but financing capability of construction companies. Since project finance is multi-complex financial supply method by various parties concerned not a single supply method, it can not succeed with one part's effort. It is also necessary to reinforce the relationship between the governments and financing companies, especially the support and regulation relax policy by the governments. As such, domestic construction companies should not consider induction of project finance as a means of acceptance a construction environment in domestic and overseas. And also it is necessary to apply in the field which researched about technology competitiveness, construction management capability and financial supply.

SM45C강의 피로균열 진전 특성과 피로수명 예측

裵原鎬,金鎭烈 慶一大學校 1992 論文集 Vol.8 No.1

Generally, machine shaft which had defect or notch might be cracked by cyclic bending or torsion. The initiated crack at the small defect on the surface of shaft propagates to failure by cyclic load. Fatigue crack growth behavior of SM45C steel was investigated and the crack growth rate was expressed by stress intensity factor range, K. Fatigue life could predicted by the use of stress or strain at the notch tip, and is known that the strain method is more effective than stress method. To estimate the fatigue life, the linear rule was adopted, base line notch factor was used to estimate the strain at notch tip. It was assumed that stress concentration foctor Kt, and strain concentration factor Ke have the same value with the base line notch factor in plain strain condition like a small notch. The estimated fatigud life was compared with expelimental result, and the predicted life was well according with experiments. So that, it was found that the method by base line notch factor is useful to predicted fatigue life of small notched round bar.

This study is aimed at evaluating the current multi-family housing projects under the site planning criteria by examining its application and design process to improve the current criteria. In order to assess the application of the current site planning criteria, two competition schematic designs were compared each other on the same land area. The research found that facilities such as retail shop, security posts, maintenance office, nurseries and libraries were not provided according to the current site planning criteria. In addition, it showed that parking lots and other community facilities did not follow the current site planning criteria but rather changed based upon individual needs. When evaluating the criteria in lieu of the number of residents and unit size, the study found that a block with more residents and smaller unit size (block A) less stringently adhered to the site planning criteria, comparing with a block that has larger unit size and less residents (block B). In order to strengthen the current site planning criteria, seven quality indicators were examined for the evaluation of the competition schematic design by per floor space and per housing unit, verifying that good design also scored well on every quality index. It was also maintained that the need to review the current criteria scope of resident and unit size, along with module size was important for the qualitative housing design.
