Many advanced countries including the U.S. consider defense standardization as a critical task for the efficient acquisition and effective operation of weapon systems and have implemented the appropriate standardization policy by synchronizing the defense acquisition strategies and nation standardization policy with defense standardization. It is required to develop the long-term defense standardization policy that can cope with the future domestic and international defense environmental changes. Therefore, it is an inevitable task to investigate the standardization trends and strategy in the domestic and international perspectives. The study aims to provide the vision of defense standardization policy, act/regulation, organization/personnel, education/training and information system.

The characteristics of concrete strength and fracture parameters of recycled aggregate concrete were investigated to apply to the concrete pavements. As the results, the early strength of recycled aggregate concrete showed to be lower than that of natural coarse aggregate concrete, whereas strength at 28 days showed to be similar. Young's modulus of recycled aggregate concrete was lower than that of natural coarse aggregate concrete due to the difference of aggregate strength. And recycled aggregate concrete contained with ground granulated blast furnace slag seemed to have an effect of strength increasing. The critical stress intensity factor of recycled aggregate concrete at the early age was increased, and converged to be similar, compared to natural aggregate concrete at later age. The reliability of two-parameter fracture model was identified by the good correlation between the theoretical value computed by P-CMOD relationship and experimental results for Young's modulus and tensile strength. 본 연구는 재생골재를 사용한 콘크리트의 강도 및 파괴특성을 고찰하므로써 콘크리트 포장체에 적용성 여부를 검토하기 위해 수행하였다. 재생콘크리트의 초기강도는 낮았으나 재령 증가에 따라 기준콘크리트와 거의 유사한 값을 나타내었으며. 탄성계수는 골재 강성 차이로 인하여 낮게 나타났다. 또한 고로슬래그 미분말을 혼합한 재생콘크리트의 강도개선효과를 확인할 수 있었다. TPFM에 의한 파괴에너지는 초기재령에서 재생콘크리트의 파괴특성이 우수한 것으로 나타났으나, 재령증가에 따라 기준콘크리트와 유사한 값으로 나타났다. 또한 P-CMOD 측정결과로부터 이론적으로 구한 탄성계수 및 인장강도와 실험으로 구한 탄성계수 및 쪼갬인장 강도사이의 상관성은 매우 높은 결과를 나타내어 시험방법의 신뢰성을 확인할 수 있었다.

Purpose: To report the case of a glaucoma patient with a history of LASIK surgery who presented with a wide discrepancy in intraocular pressure between the Goldmann applanation tonometry and non-contact tonometry. Methods: A 20-year-old male glaucoma patient was referred to our clinic with a chief complaint of blurred vision in his right eye. The patient had a history of uneventful bilateral LASIK surgery. Upon our initial examination, his best-corrected visual acuity in the right eye was 0.04 and his right eye IOP was 14 mmHg by Goldmann applanation tonometry and 40 mmHg by non-contact tonometry. A slit lamp examination showed corneal epithelial edema with diffuse interface opacities. The central corneal thickness in the right eye was 587 ?m. An ultrabiomicroscopy demonstrated an interface fluid accumulation between the LASIK flap and the stromal bed. The patient was diagnosed with juvenile open-angle glaucoma and was scheduled for a trabeculectomy. Results: Seven days after trabeculectomy, the patient`s vision in the right eye improved to 0.7 and his IOP was 12 mmHg by Goldmann applanation tonometry and 14 mmHg by non-contact tonometry. In addition, the corneal epithelial edema, interface opacities, and fluids had all resolved and the central corneal thickness was reduced to 489 ?m. Conclusions: In eyes that have undergone LASIK surgery, the IOP measured by Goldmann applanation tonometry may underestimate the true pressure due to fluid accumulation under the LASIK flap. In such cases, non-contact tonometry can be a convenient and a reliable method for determining treatment plan.

Purpose: To investigate the clinical characteristics and treatment of intermediate uveitis under new diagnostic standards. Methods: Medical records of patients diagnosed with pars planitis or intermediate uveitis were followed for more than 6 months, and retrospectively reviewed. Results: A total of 90 patients and 117 eyes were enrolled in the study. The mean age was 40.1 years, and the mean follow-up period was 43.0 months. Thirty percent of cases were bilateral. The most common initial symptom was decreased visual acuity. Snowbank was detected in 39.3%, snowballs in 15.4%, vitritis in 96.6%, and vasculitis in 56.4%. Common complications includedcystoid macular edema (57.3%), cataracts (43.6%), and epiretinal membrane (36.8%). Therapies included topical steroids (82.9% of cases), posterior sub-Tenon steroid injection (45.3% of cases), systemic steroid administration (67.8% of cases), and immunosuppressants (28.7% of cases). Vitrectomy was performed in 11.1% of patients due to complications such as epiretinal membrane and traction retinal detachment. The mean initial and final visual acuities were 0.67 and 0.74, respectively. Conclusions: The patients in this study experienced various courses of symptoms that required different treatment plans. Future investigations may corroborate these results.

고삼이 항암제 cisplatin의 췌$\cdot$심장 부작용 감소에 미치는 영향
김진철,임성철,정태영,서정철,한상원,Kim, Jin-Cheo,Lim, Seong-Chul,Jung, Tae-Young,Seo, Jung-Chul,Han, Sang-Won 대한동의생리학회 2005 동의생리병리학회지 Vol.19 No.3
The objective of this study is to investigate the inhibitor effects of an traditional oriental herb, Sophora flavescens on the pancreatic & cardiac side effects of chemotherapy were studied by using Bl6-BL6 melanoma-injected C57BL6 mouse tumor model. In this study, the effects of an traditional oriental herb, Sophora flavescens, on the side effects of chemotherapy were studied using B16 melanoma-injected C57BL6 mouse tumor model. Anticancer drugs widely used in clinical situation. Sophora flavescen has significant effect on the reduction of the side effects of chemotherapy. Water extract of Sophora flavescens significantly inhibited cisplatin-induced increase of amylase (AMY) which is a good indicator of pancreatic toxicity. Sophora flavescens extract does not decrease the anti-tumor activity of cisplatin showing that it can selectively inhibit side effects of anticancer drugs preserving beneficial effect. Theses results suggest a possibility that Sophora flavescens extract can be used for cancer patients for the reduction of the side effects and improving the quality of life during chemotherapy of cancer patients.

사회적 재교육으로서 도예교육의 전개 양상에 관한 연구 - 고령 사회에서 도예교육의 방향과 역할에 관하여 -
김진철 ( Kim Jin Chul ),원주안 ( Won Ju An ) 한국기초조형학회 2018 기초조형학연구 Vol.19 No.6
산업화 사회의 급속한 발전은 생활의 편리함을 가져다주었지만, 그 이면에 인간소외와 자존감 상실 등의 제반문제들도 야기해왔다. 사회적 재교육 프로그램이 이러한 문제들을 해결해 나가는데 큰 역할을 하였고, 특히 도예평생교육은 사회 구성원들에게 정서적 치유를 통한 마음의 안정을 주고 잃어버린 자신감을 회복하는데 도움을 주는 매개체로서 그 역할을 담당하였다. 본 연구는 이런 도예 평생교육 과정이 우리사회에서 보다 효과적인 성장을 할 수 있도록 가장 체계화 된 외국의 현황을 살펴 그 차이점과 발전방향을 모색하고, 더불어 실버계층이 중심이 되는 다가올 미래의 공동체에서 도예교육이 담당해야 할 역할에 관해 제언하는데 목적이 있다. 이를 위해 먼저 기존의 연구와 문헌에 근거하여 평생교육의 개념과 역사를 살피고, 평생교육으로서의 도예교육의 역할을 밝히기 위하여 정서적인 치료의 기능을 고찰하였다. 또 국내보다 먼저 평생교육 과정을 운영해 온 미국, 캐나다, 뉴질랜드, 일본의 대학들을 조사하여 평생교육의 역사와 도예평생교육의 현황에 대해 살펴보고 국내의 교육환경과 비교하였다. 비교 결과를 보면 우리나라의 재교육도 외형적으로 드러나는 물리적인 환경에 있어서는 앞선 다른 나라들에 뒤지지 않을 정도의 성장을 이루었다는 것을 알 수 있다. 하지만 구성원들과의 긴밀한 소통과 협력 등 내적인 성장은 아직 외국의 경우에 비해 부족함을 보이는 것 또한 사실이다. 사회는 급격히 변화하고 있고, 그 변화는 우리사회도 예외일 수 없다. 이런 사회적 변화 속에서 우리나라 도예교육이 그 목적을 상실하지 않고 사회교육의 한 분야로서 훌륭하게 역할을 소화해 나가기 위해서는 특수화된 도예치료프로그램등과 같은 타 분야와의 체계적인 협업을 통한 구성원들과의 적극적인 소통이 필요하다. 그리고 국가와 지역사회의 지속적인 관심과 지원을 통한 안정적인 교육체계로서의 성장과 전문인으로 연계되어지는 교육의 전환이 절실히 필요하다고 하겠다. The rapid development of the industrialized society did not only bring a convenience of life, but also caused various problems such as human alienation and a loss of self-esteem. At this time, the social reeducation program played a large role in solving these problems. In particular, the ceramic lifelong education played a role as a mediator for restoring lost self - confidence through emotional healing. The purpose of this study is to investigate the current status of the most systematic foreign countries in order to enable more effective growth of the ceramics lifelong education curriculum in our society. In addition, the purpose of this study is to suggest the role of the lifelong education. For this reason, I described the concept and history of lifelong education and the function of emotional therapy through literary study to emphasize the necessity of pottery education as lifelong education. Also, looking into the development of lifelong education in the precedent countries, we can understand and utilize ways in which to develop our education system for the better. In keeping with the development of society, Korean ceramic education needs to communicate actively through systematic collaboration with other fields such as therapeutic programs in order to digest it’s role as a part of social education without losing it’s purpose. It is necessary to grow as a stable education system through continuous interest and support of the national and local community and to transform the education linked to professional life.
