  • 인체의 뼈와 같은 손상된 경조직을 치료 또는 대체하기위한 정형외과용 임플란트를 설계하는데 있어 뼈의 생체역학적 특성과 유사한 성질을 갖는 다공성 지지체에 대한 연구가 최근 관심을 끌고 있다. 다공성 지지체는 조직이 원활히 재생될 수 있어야 하며, 또한 주변 조직과도 생물학적인 고착이 잘 되도록 기공들이 상호 연결된 구조를 가져야 한다. 이와 같은 다공성 지지체용 소재를 제조하기 위하여 본 연구에서는 타이타늄 분말을 사용하여 3차원 적층조형공정으로 다공성 타이타늄 지지체를 제조하였다. 제조된 다공체의 물성 및 기계적 특성을 평가하기 위하여 압축시험과 변형해석을 수행하였으며, 아울러 제조된 지지체의 생체적합성 향상을 위하여 양극산화 공정 등의 표면처리를 수행하여 그에 대한 특성을 평가하였다. 분말야금 공정으로 제조된 지지체는 골조직의 성장에 적합한 약 $300\sim400{\mu}m$의 기공 크기를 갖도록 제어하였고, 기공도는 60~75%로 제어하였다. 아울러 다공성 타이타늄의 생체적합성을 부여하기 위하여 양극산화공정으로 지지체의 표면에 Ca 및 P을 포함하는 산화층을 형성시키는 표면처리를 수행하였다. 양극산화공정에 의하여 표면에 미세기공을 포함하는 산화층을 형성시킬 수 있었으나 이와 같은 표면구조는 조골세포의 부착과 영향에는 큰 영향을 미치지 않는 것으로 확인되었다.

  • Objective : This research was carried out to find out the general understanding of korean medicine and the attitude toward medical gigong among common people. Methods : Randomly selected 297 people participated in this research. We performed this survey with 13 items on the Questionnaire Results : 13.1% of respondents knew qigong training, and 7.1% of respondents knew medical qigong. Most respondents knew one or more terms of qigong. Among them, the order was known as meridian, danjeon, sojucheon. 57.6% of respondents had a mind to be in a treatment of medical qigong. And 45.7% of respondents were satisfied with the harmless of medical gigong. However, 41% were unsatisfied with the low effect of the treatment. Conclusions : Medical gigong treatment need to develop an explanatory model which based on static study. And technically advanced public relations are needed.

  • Research studies of Qigong therapy for cure for the past 20 years were reviewed from three different categories: clinical study on human patients, in-vitro study of abnormal cells, and in-vivo study of abnormal cell with Qigong therapy, in an attempt to understand the role Qigong therapy plays in many kinds of disease. There is a lot of evidence suggesting that Qigong therapy has an inhibitory effect on abnormal cell growth, both in vitro and in vivo studies, as well as in clinical observation (often there was room for improvement in these studies and some studies require replication in order to verify their findings). Qigong therapy is an area that is often neglected by mainstream medicine and research, and it should be seriously examined and considered as an important supplement to conventional treatment.

  • Objective : The purpose of this study is to identify the trends of vibration(or wave) therapy in Korea, to actively utilize vibration(or wave) therapy, and to help research activities of vibration therapy in Korean Medicine. Methods : The following Korean words "진동기", "진동요법", "진동운동", "진동치료", "파동요법", "파동운동", "파동치료" were searched on three specialized search sites (RISS, NAL, DBpia). Trends of vibration therapy were analyzed through the selected researches suitable for this study among these searched researches in an overview format. Results : 1. A total of 8,116 studies were searched and a total of 365 studies were finally selected 2. From 2000 to 2019, when research began to increase in earnest, there were 17.45±10.28 studies per year, and the AGR(Average Annual Growth Rate) was 11.92%. 3. In the main field of research, the 'Medicine and Pharmacy' was the largest with 147(40.16%) studies. In the Middle Field, the 'Kinesiology' was the largest with 99(27.05%) studies. In the study design, 'RCT(Randomized Controlled trial)' was the largest with 138(47.75%) studies. In the Age Group, 'Youth' was the largest with 126(48.84%) studies. 4. The average of the number of participants was 24.90±17.44. 5. The most used Intervention was the 'WBV(Whole Body Vibration)' with 177(61.25%) studies. 6. The average of Intervention Period was 5.99±4.14 weeks, while the maximum was 36 weeks. 7. The journal that published the most research papers is 'K. J. of Sports Science(체육과학연구;13)', and the society is 'Rehabilitation Engineering And Assistive Technology Society of Korea(한국재활복지공학회; 14)'. The University that published the most dissertations is 'Sahmyook University(11)'. 8. The authors who published the most studies are Ju-Hwan O(8) as the main author and Tae Kyu Kwon(18) as the co-author (including the thesis Director). In an integrated analysis of the authors and co-authors, Tae Kyu Kwon published the most numerous studies(19) Conclusions : 1. The study of vibration or wave therapy has been increasing noticeably every year. 2. The major academic Fields studying vibration or wave therapy are the 'Kinesiologic Field', 'Physical Therapy Field', and 'Biomedical Engineering Field'. 3. The most chosen method of study design on vibration or wave treatment was 'RCT', and there was no significant change in the annual presentation rate. 4. Types of vibration or wave therapy could be classified as 'LVS(Local Vibration Stimulation)', 'WBV(Whole Body Vibration)', 'MV(Micro Vibration)', 'BV(Bio Vibration)' and 'SWV(Sound Wave Vibration)', and the study on Whole Body Vibration is most active. 5. Most of the studies of vibration or wave therapy were on musculoskeletal systems, but there were very few studies on internal diseases.

  • Objective : The purpose of this study is to understand trends of pelvic correction therapy in Korea and to assist research activities on pelvic correction therapy. Also, this study selected and presented indicators for measuring pelvic slope to help ensure consistent studies with uniform indicators in future studies related to pelvic correction. Methods : The following keywords "골반", "골반 교정", "골반 변위" "Pelvic correction" were searched on three specialized search sites (RISS, NAI, DBpia). Trends in pelvic correction therapy were analyzed through the selected researches suitable among these searched researches in an overview format. Results : 1. A total of 7,806 studies were searched and a total of 268 studies were finally selected. 2. Studies began in 1977 and have been actively studied until recently, with 35 studies in 2017 being the most recent trend since 2000. 3. In the results according to the Main Field of Research, the 'Arts and Kinesiology'(113, 42.16%) and 'Medicine and Pharmacy'(103, 38.43%) were the most in order. To the Middle Field, the 'Kinesiology was the largest with 96(35.82%) studies. 4. In the results according to the study design, 'Pre-Post Test(PPT)' was the largest with 107 studies. 5. In the results according to the Intervention, 'Exercise' was the largest with 165 studies, of which 'Pilates' and 'Yoga' in 'Training' was the largest. 6. Among the evaluation method, the 'Pelvic Index' was used 146 times, followed by 'Spinal Alignment (99)', 'Other Joints (93)', and 'Kinetic Specialized Measurement Test (56)'. 7. Among the evaluation methods, the pelvic slope measurement indicators were PT (58), PH (48), Pelvic Torsion (40), Iliac Crest (38), ASIS-PSIS distance/angle (27), and Pelvic Width (I.W., I.L., S.W) (25) in order. 8. The journals that published the most researches were KJSS(Korean Alliance For Health, Physical Education, Recreation, And Dance;9), and JKPT(Korean Physical Therapy;9). Among the University, the Graduate School of Silla University published the most papers (12). 9. The author who published the most studies were Seungjin Park(3), the co-authors were Hoseong Lee, Gideok Park, Seongsu Bae(3), and the Thesis-Director Gyeongok Lee(7). Conclusions : 1. Studies on pelvic correction treatment continue to increase every year. 2. The main academic field of pelvic correction is 'Sports', 'Physical Therapy', and 'Medical Science'. 3. The most chosen research design method in the study on pelvic correction treatment was 'Pre-Post Test(PPT)', primarily as an intermediary, Pilates and yoga during exercise therapy, and then Chiropractic during handcraft were used as multiple frequencies. 4. Among the various measurement method indicators of pelvic correction previously used, multiple frequency was taken up in the order of PT, PH, Pelvic Torsion, iliac crest, ASIS-PSIS distance/angle, and pelvic width (I.W.,I.L.,S.W). Typically, measurements through "ASIS-PSIS angle" are recommended and are considered as the most rational in clinical trials.
