Objectives: This study is to observe the effect of oriental medicine treatment combined with Soyeom pharmacopuncture therapy on traumatic rupture of intervertebral disc patients caused by traffic accidents. Methods: The patients who have traumatic rupture in lumbar(L)-spine(case 1) and cervical(C)-spine(case 2) were treated by oriental medicine treatment in combination with Soyeom pharmacopuncture therapy. VAS(visual analog scale), ROM(range of motion), and physical exam were checked on a daily basis while NDI(neck disability index) and ODI(Oswestry disability index) were examined for 3 times at 7 day interval. Results: 1. For 8-9 days from the admission day, the sole use of oriental medicine treatment did not make many improvements in the case of two patients` symptoms. After combining with Soyeom pharmacopuncture therapy, chief complaints were improved significantly. 2. In case 1, lumbago decreased from VAS 10 to VAS 5 and lumbar ROM got better than before. ODI score dropped from 42 to 27. 3. In case 2, left shoulder pain and nuchal pain lowered from VAS 10 to VAS 4. left upper limb numbness and weakness were improved. The patient showed nearly full ROM. NDI score decreased from 26 to 19. Conclusions: Oriental medicine treatment in combination with Soyeom pharmacopuncture therapy is proved to be helpful to improve the symptoms of the traumatic rupture of intervertebral disc patients caused by traffic accident.

소방호스 전개 상태에 따른 압력손실 실험연구

이형은(Hyung Eun Lee) 국립소방연구원 2020 소방안전연구 Vol.1 No.1

본 연구에서는 평지에서 소방호스 전개 상태에 따른 압력손실을 피에조미터로 측정하였다. 측정 결과 소방호스가 많이 꺾일수록 압력손실은 커지는 것으로 측정되었다. 소방호스 3개가 180도 꺾인 상태에서의 압력손실이 71.9%로 최대치였다. 이처럼 소방호스 전개 상태에 따라, 방수압력과 유량이 충분하지 않아 화재진압능력이 저하될 가능성이 있다. 현장대응을 보다 효율적으로 하기 위해 소방호스의 상태별 압력손실값은 유용한 정보가 될 것이며, 현장에서는 이를 참고하여 소방호스의 압력손실을 고려한 소방호스 전개가 이루어지기를 기대한다. This study reviews water pressure loss in fire hoses under various deployment situations. Pressure loss was measured using a piezo-meter connected next to the nozzle. Water pressure loss was measured by varying the number of fire hoses and the folding angle. According to the measurement, the pressure loss rate was the highest at 71.9 percent when three fire hoses were folded at 180 degrees. The other words, pressure loss in fire hose may also occur due to various deployment situations of the fire hose. Pressure loss may reduce firefighting capacity by reducing the water pressure and water flow below the level required for putting out the fire. Therefore, this study measures pressure loss under various deployment situations and propose ways to minimize pressure loss.

Objectives :This study was designed to compare wet cupping with dry cupping on acute cervical and lumbar sprain patients by traffic accident. Methods :This study was carried out on the 90(dropout=5) acute cervical and lumbar sprain patients by traffic accident. We divided these patients into 2 groups. Group A was treated with the dry cupping and Group B was treated with the wet cupping once a day for five days. All patients were treated with acupuncture, physical therapy and herbal medicine along with two types of cupping therapy. We measured visual analogue scale(VAS), neck disability index(NDI), Oswestry disability index(ODI) twice(pre-treatment(Tx.) and post-Tx.) and conducted satisfaction questionnaire after treatment. Results :1. The VAS score, NDI score, ODI score were statistically decreased after treatment in all patients. 2. The VAS score for nuchal pain of females, low back pain of 40 to 50s patients, overweight and normal weight in Group B was statistically lower than those of Group A after treatment. 3. Two types of cupping therapy received a favorable evaluation from each group in satisfaction questionnaire. Especially, Group B showed a higher percentage in excellent and improved items than Group A did. Conclusions :In this study, Two types of cupping therapy were highly effective on acute cervical and lumbar sprain patients. But wet cupping was more effective than dry cupping in reducing the initial pain. And wet cupping was more effective in female, 4~50s patients.

Objectives This study was carried out to find out the anti-osteoarthritic effects of Ma-hwangbujaseshin-tang (Mahuangfuzixixintang) on the monosodium iodoacetate (MIA)-inducedosteoarthritis rats. Methods Osteoarthritis was induced by injecting MIA (50μl) into the knee joint of rats. Rats were divided into a 3 groups (n=7). The injection did not fit the normal group. A week later, after the injection of MIA, while control group took normal saline 2 ml, the extract of Mahwangbujaseshin-tang (Mahuangfuzixixintang) (MBST) (200 mg/kg) was injected to treated group. After that, we examined hind paw weight bearing ability, functions of liver and kidney, serum TNF-α, IL-1β, IL-6, PGE2, LTB4, TIMP-1, MMP-9 and hematology. Volume of cartilage was measured by micro CT arthrography. Injury of synovial tissue was measured by H & E, Safranin-O immunofluorescence.Results1) DPPH and ABTS free radical scavenging activity of MBST was increased ac-cording to concentration of MBST and total phenolic contents were in high level. 2) In RAW 264.7 cells, ROS production was significantly decreased in MBST (at 10, 100μg/ml) and NO was also decreased but meaningless in MBST (at 100μg/ml). 3) In RAW 264.7 cells, IL-6 production was significantly decreased in MBST (at 100μg/ml) and TNF-α and IL-1βproduction were also decreased but meaningless in MBST (at 100μg/ml). 4) In hind legs weight-bearing measurement, level of weight-bearing was increased. 5) Functions of liver and kidney were not affected. 6) TNF-α, IL-1β, IL-6, PGE2, LTB4, MMP-9 and TIMP-1 production were significantly decreased. 7) In hematology, the levels of neutrophils, mono-cytes were significantly decreased and the levels of white blood cells, lymphocytes were al-so decreased but meaningless. 8) In micro CT-arthrography, cartilage volume was sig-nificantly increased. 9) Histopathologically, injury on cartilage and synovial membrane of MBST group was decreased. Conclusions Based on all results mentioned above, Mahwangbujaseshin-tang (Ma-huangfuzixixintang) is believed to be meaningful for suppressing the progress of osteoar-thritis. And it is related to inhibiting the activity of inflammatory cytokine and injury of volume in cartilage. (J Korean Med Rehab 2014;24(2):65-81)

Conventional progress control technique which collects and manages construction progress data manually is involved in inaccurate and omitted information in construction phase. It is time consuming and labor intensive to acquire the construction operation data in detail. It is important to develop the system that analyzes the project performance accurately and control the progress efficiently by keeping track of the progress data at a lower level than the operation. This paper proposes a system prototype which measures project progress at the construction operation level by hybridizing remote-controlled robots (i.e., air-drone and wheel mounted vehicle), smart sensors, and project scheduling and controlling tool. The system is developed into an Internet of Thing(IoT)-based progress measurement system. using robot and information technology. Earned value method-based physical progress measurement method is utilized to compute the quantity of work completed. A test case was performed to confirm that the new system complements the limitation of existing progress control method.

1977년 7월부터 1987년 6월까지 10년간 연세대학교 의과대학 치료방사선과에서 방사선 치료를 받았던 135명의 비인강암 환자 중 치료시작 당시 조직학적으로 확진되지 않았던 환자, 원격전이를 동반하고 있었던 환자 및 방사선 치료를 완료하지 못한 환자 30명을 제외한 105명 환자를 대상으로 원격전이의 빈도, 양상 및 예후를 분석하였다. 원격전이 진단은 임상증상과 방사선 소견으로 하였으며, 대상환자 105명중 원격전이를 보인 환자는 26명으로 원격전이율 24.8%였으며, 원격전이의 장기는 이전의 다른 보고들에서와 마찬가지로 골전이(50.0%)가 가장 많았고, 다음이 폐(19.3%), 간(11.5%), 뇌(7.7%) 순서였다. 원격전이에 영향을 미치는 인자로 연령, 성별, AJC의 T병기, N병기, Ho의 T병기, N병기, 조직세포유형 및 치료방법등을 분석해 보았으나 Ho의 N병기에서만 N0, N1, N2, N3로 감에따라 원격전이율이 증가하는 양상을 보였다 (p One hundred and thirty five patients with carcinoma of the nasopharyx were treated by radiation therapy in the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University between August 1977 and July 1987. Of the 30 patients ommitted : 8 had distant metastases at initial diagnosis or during radiotherapy; 18 patients refused or did not receive a full course of radiation therapy, and four had not been confirmed histologically. The remaining 105 patients were analysed to determine the incidence and pattern of distant metastases. Diagnosis of distant metastases was made based on clinical signs and radiography. even though histologic confirmation was not made. Twenty-six patients developed distant metastases after definite irradiation of nasopharyx and neck, an incidence rate of 24.8%. The common sites of distant metastases were, in descending order, bone, lung, liver, and brain. There was a strong correlation between Ho's N stage and distant metastases rate. But sex, age, histologic subtype(squamous cell and undifferentiated cell), AJC T and N stage, treatment modalities (radiotherapy alone and radiothergrapy combined with chemotherapy) were not significant. Of those patients who develop distant metastases, 80.8% were discovered within 2 years of their radical radiotherapy. The prognosis for nasopharyngeal carcinoma patients developing distant metastases was poor : median survival was nine months and 80% of those patients died whthin two years of the initial diagnosis of distant metastasis.
