The purpose of this study is to observe the effect of Cordyceps Militaris(CM) complex extract treatment on patients diagnosed with rheumatoid arthritis(RA). We reviewed medical records of 9 rheumatoid arthritis patients who visited the pain & rehabilitation center, Daejeon Korean Medicine Hospital of Daejeon University and were treated with CM complex extract from October 14, 2019 to October 14, 2020. We analyzed the records of DAS 28(Disease Activity Score 28), CDAI(Clinical Disease Activity Index), SDAI(Simplified Disease Activity Index), VAS(Visual analogue Scale), and KHAQ-D(Korean Health Assesment Questionnaire-Disability Index) before and after treatment to evaluate the effects of CM complex extract on RA. As a result, the scores of DAS 28(p<0.05), CDAI(p<0.01), SDAI(p<0.01) and VAS(p<0.01) were statistically significantly decreased, after 8 weeks of taking CM complex extract in RA patients. In conclusion, CM complex extract treatment may have potential effects of reducing disease activity and pain and improving quality of life in patients diagnosed with RA.

Herniation of intervertevral disc(HIVD) is the most common disease causing low back pain. Acupuncture, electroacupuncture and moxibustion has been used for treatment of HIVD. Bee venom (BV) also has been traditionally applied to relieve pain. Recently, it has been reported that BV is effective in treating HIVD. But more objective methods were required to assess the efficacy of BV on HlVD. So we assessed of BV-acupuncture effect on herniated disc patients by use of rating scale for low back pain. We researched 22 patients who were treated at Department of Acupuncture & Moxibustion, Kyung Hee Medical Center from January 1999 to June 1999. The patients were diagnosed by MRI as having a herniated disc. The results of treatment using rating scale for low back pain in HIVD showed that $43.77{\pm}14.39$ point of pre-treatment score and $84.5{\pm}3.97$ point post-treatment score. The improvement index showed $0.43{\pm}0.15$. Especially, clinical score of neurologic deficits showed most highest improvement index of $0.7{\pm}0.45$. Assessment of BV-acupuncture Effect by MRI finding were showed that protruded disc and extruded disc got more higher improvement index than bulging disc. Among 22 patients, satisfactory assessment of BV-acupuncture effect showed that 15(68.2%) were excellent, and 7(31.8%) were good. The result suggest that BV-acupuncture is good method for treatment of HIVD.

세계적으로 천연가스는 환경적, 정치적, 지역적인 이유로 중요한 에너지원으로 부상하고 있다. 우리나라에서 천연가스는 액화천연가스로 수입하고 있으며, 석탄과 원전을 대체하는 연료나 원료의 활용에서 액화천연가스는 증가하고 있다. 우리나라는 천연가스를 수입에 의존하고 있기 때문에 공급에 대한 안정성분석이 중요하다. 따라서, 본 연구에서는 우리나라 수입구조의 위험도 분석을 통하여 공급리스크를 줄이고 안정적인 공급과 수요를 위한 방안을 제시하였다. 공급위험도를 감소시키기 위해 한 국가로부터의 수입 집중도를 낮춰야 하며, 가스공급안정성 지수 (gas supply security index, GSSI)가 낮은 국가의 수입비중을 낮추고 상대적으로 안정적인 국가인 러시아로부터 수입을 증가시켜야 한다. 또한, 수입국가의 수를 늘리거나 안정적 공급이 가능한 국가와의 관계 유지는 우리나라 수입가스의 공급안정성지표 (total gas supply security index, TGSSI)에 긍정적인 영향을 줄 것으로 분석되었다.

In general, it is known that the concrete ballast track is possible to reduce a cost of maintenance activities cause of maintenance free by restrictive maintenance in application of track ballast structures. However, if deteriorations and fracture mechanism of a material are considered, proper maintenance activities and repairing are continually required. For the problems, we evaluated an economical efficiency of the gravel ballast and the concrete ballast on a proper level of maintenance activities. As the method based on history path is difficult to obtain sufficient reliabilities cause of an absence of real data for maintenance activities, we chose the delphi survey method by professional group, and we obtained the appropriate index and profiles for maintenance activities. As a result, we founded that effects for cost reduction can be expected by preventive maintenance management, and we proposed economical restrictions and life cycle cost for track ballast structures in a life cycle.

The purpose of this study is to computerize street tree management using a CAD program in order to manage the drawing record of street trees systematically and concurrently. The configuration of this program is composed of Reference Data, Data Inquiry, and Cost Assessment. The Reference Data includes characteristics of trees, monthly managements records, damage by blight and insects and usage of pesticides. The Data Inquiry includes an individual search of the tree index, simple searches and multiple searches. The Cost Assessment includes two main components, the data input with labor cost, manure ocst and pesticide cost and the assesment of management cost for prevention of blight and insects, pruning and fertilization. The results of this study are as follows: 1) When there are practices such as transplanting and removing of street trees it is immediately updated with the various situation. By creating an in progress a tree management system, up to the date information can be given to the manager for decision making. 2) To identify individual tree at the site or in drawing, the street name and numbers were used instead of coordinates. Tree tags are attached to the street trees individually. It can make DB management simple and easy. 3) By doing simple or multiple search with constructed DB, data can be provided quickly. 4) The result of this type of search are useful in the assessment of management cost very useful in regards to items such as the pruning, pesticides scattering and fertilization. 5) By using the AutoCAD software and existing PC without purchasing new equipment, the cost of system implementation can be minimized.

Connectivity is a quantitative indicator of landscape structure, and connectivity of urban green areas is an indicator of ecological integrity in urban landscapes. The purposes of this study are to assess the connectivity of urban green areas in Seoul, and to develop a method of siting new green areas for better connectivity. Diverse methods for connectivity assessment and indices of connectivity are reviewed and applied to the connectivity assesment of green areas in Seoul. The indices of connectivity of green areas in Seoul turned out to be higher than expected, maybe because many of them are rather evenly distributed, serving as stepping stones, and because there are many riparian corridors, including the Han River. Analysis also shows the optimum location of new green space patches or corridors will be those spots that would link the mainland, or large green areas outside the city, and existing green areas in the city. Restoration of urban streams as ecological corridors will significantly enhance connectivity. Three different scenarios with increasing numbers of new green areas in the city were then prepared. The changes of connectivity were measured and the possible success rates of animal dispersal were simulated. The results revealed that restoration of streams will increase the connectivity and success rates of animal dispersal.
