  • 중약진 지역으로 분류되고 있는 대만에서 1999년에 발생된 예상치 못한 막대한 경제적 피해와 사상자를 기록하였다. 대만과 마찬가가지로 중약진지역으로 분류되는 우리나라에서도 지진발생시 많은 문제발생이 예상됨에 따라 기존건물의 내진성능평가의 필요성의 인식하게 되었다. 본 연구에서는 미국과 일본에서 이미 적용되고 있는 기존 건축물의 내진성능 평가 기법을 분석하고 이를 3층 규모의 모멘트 골조 건물에 적용하여 평가해 보았다. 평가는 일본건축방재협회에는 철근콘크리트 구조물의 내진성능평가 규준을 적용하였다.

  • Most of seismic design code provisions provide the design response spectra for defining design earthquake ground motions. The design spectra in the code provisions generally come under the 5% of critical damping value, which corresponds to the responses of common structure under the design earthquake. Energy dissipation devices and seismic isolation systems became more popular and the design response spectra at higher damping levels are required. Damping coefficients can be effectively used in conversion of 5%-damped design spectra into other damping levels. These coefficients in the current seismic design code provisions are based on the strong ground motion records. Since the weak and moderate earthquake data have different characteristics from those of strong earthquake data, the application of these coefficients should be investigated in the weak and moderate earthquakes zones. In this study, damping coefficients based on the weak and moderate ground motions were developed and compared to those of current seismic design code provisions.

  • Background: Hemorrhoid surgery is a frequently performed surgery in Korea, second only to cataract surgery. However, it has serious complications, including bleeding, infection, anal stenosis, and urinary retention, so active conservative therapies are in need at an early stage. Case summary: Thirteen patients with anal disease complained of main symptoms of pain, bleeding, and prolapse, with additional complaints of itching and mucus discharge. An herbal medicine mixture of Eulja-tang and Hwangryeonhaedok-tang was administered twice daily, and dry cupping therapy, acupuncture, and hot pack placements were administered on pelvic and sacral regions once weekly for four weeks. The symptoms were evaluated before and each week after the treatments. The treatments had statistically significant therapeutic effects. Conclusion: Korean medicine treatment-effectively alleviating the symptoms of anal disease, such as pain, bleeding, and prolapse-may represent an alternative therapy for conservative treatments in the early stages of anal disease.

A Study on the Characteristics of the Awareness and Satisfication Level of Musculoskeletal Patients and Non-Musculoskeletal Patients that Use Korean Medical Institutions (한방의료기관 이용자 중 근골격계질환자와 비근골격계질환자의 인식도 및 만족도 특성연구)

  • Background : The study aimed at examining the awareness and satisfaction level of Korean medicine treatment of musculoskeletal patients and non-musculoskeletal patients. Method : The frequency and percentage were calculated to identify the overall characteristics, and to identify the characteristics of the respondents who visited the hospital to treat musculoskeletal diseases and those who visited for the treatment of non-musculoskeletal diseases, the correlation between the variables was analyzed using the chi-square analysis (χ2-test). Furthermore, analysis items were compared depending on detailed diseases within the musculoskeletal disorder (lumbar pain, sprains, arthritis, frozen shoulders, spondylitis, disc) Result : Respondents who used Korean medicine for the purpose of treating musculoskeletal diseases had answered that costs involved in Korean medicine was expensive, and answered that herbal decoction was the preferred Korean medicine treating method for expanding health insurance benefits. Regarding the safety awareness of Korean medicinal herbs, responses that said it was safe was high, and their willingness to use and recommend Korean medicine in future was also high. Respondents who used Korean medicine for the purpose of treating musculoskeletal diseases said they were overall satisfied along with the attitude of Korean medical doctors, treatment results, and costs of treatments. Conclusion : The study was aimed at securing basic data to indirectly identify the national demand for Korean medicine, through investigating the level and degree of differences that exist in the perception and satisfication level and further find a point where policy intervention is possible in future.

  • Objective : The purpose of this study is to analyze Korean patients' characteristics, who were concurrently treated with both Korean herbal medicines and Western chemical medicines using nation-wide database. Method : Using the patients sample data (HIRA-NPS 2018) provided by Health Insurance Review and Assessment Service, a group of patients who co-administered Korean herbal and Western medicines was selected, and their basic characteristics, diagnosis, and prescribed chemical medicines were analyzed. Results : Out of the 1,481,921 sample population, 17,629 patients (1.2%) were selected as a concurrent medication group. Compared to the whole sample, the concurrent medication group was composed of more women (65.8% vs. 51.1%), the more elderly people (65 or older years old) (44.5% vs. 14.6%), and the higher prevalence of chronic diseases (49.1% vs. 22.2%). The most frequent diagnosis treated with Western medicines was mental and behavioral disorders, musculoskeletal and circulatory disorders. Frequently used drugs among concurrent medication group were anti-anxiety drugs, gastric ulcer treatment drugs, and senile diseases treatment drugs. Conclusion : The evidence reported in this study is expected to provide herb-drug interaction researchers with important reference to set the priorities of research topics in the future.
