최근 국내 건설 분야에서 BIM의 활용이 늘어나고 있는 추세이지만 도면을 포함하는 BIM 설계가 아닌 주로 내·외부 시각화와 같은 단순 활용에 그치고 있다. 이에 대한 원인으로 여러 연구에서 BIM 설계에 필요한 라이브러리의 부족과 경제적인 문제를 지적하고 있다. 즉, 경제적으로 영세한 대다수의 국내 설계사무소 입장에서는 필요한 BIM 라이브러리를 직접 제작하여 사용하기 위한 비용과 인력 투자가 힘들어 BIM 설계 활성화에 부정적 요인으로 작용하고 있다. 따라서 라이브러리를 경제적이며 쉽고 빠르게 공급받을 수 있다면 BIM 설계가 보다 적극적으로 이루어 질 수 있을 것이다. 본 연구에서는 기존 건축자재선정업무와 BIM 라이브러리를 고찰하여 경제적이며 쉽고 빠르게 BIM 라이브러리 서비스를 제공할 수 있는 BIM 라이브러리 비즈니스 모델과 고려요소들을 제시하였다. 제시한 비즈니스 모델은 국내에서 절대적으로 부족한 BIM 라이브러리 공급자를 늘려 적은 비용과 노력으로 효과적인 BIM설계가 가능하도록 할 것이다. 본 연구에서 제시한 비즈니스 모델을 반영한 서비스가 이루어진다면 설계, 시공, 유지관리 단계에서 일관된 정보공유가 가능한 통합데이터베이스가 구축될 것이다. 구축된 데이터베이스를 이용하면 건축물의 생애주기 동안 자재 및 설비 정보의 변화를 모니터링할 수 있기 때문에 자재 및 설비의 개량은 물론 효과적인 설계와 유지관리를 위한 실적데이터로 활용될 수 있을 것이다. In the injection molding process, a core that builds a space for a product is installed at the internal place in the mold and fabricated as the frame of the mold. In this make up, the fabricating partial form of the mold at a pin is a core pin. The core pin is finer because an injection mold produces miniaturization and integration. On the other hand, when the core is manufactured using the existing centerless grinder, it generates vibrations because of the lack of a fixed zig for a micro size workpiece. For this reason, an existing centerless grinder without a micron size fixed zig, makes a defective product due to vibration and deformation. In this study, a compact grinding system that can be installed using an existing centerless grinder was fabricated to make a micro size core pin. Using the compact grinding system, grinding experiment for core pin was carried out. The performance of the system was confirmed by measuring the surface roughness, roundness, and cylindricity.

Objective. To assess the efficacy and safety of rituximab (RTX) on disease activity and muscle strength in patients with inflammatory myopathies refractory to conventional therapy. Methods. Four inflammatory myopathy patients who had been refractory to glucocorticoids, one or more immunosuppressive therapies and intravenous immunoglobulin were treated on an open-label basis. Each patient received two 500 mg doses of RTX 2 weeks apart in one cycle. In one patient who did not respond after the first cycle of RTX, the infusion schedule was modified by the physician. We measured muscle enzyme including CPK, LDH and assessed muscle strength individually to evaluate RTX response. Additionally anti-CD19 antibody was measured. Results. Three patients responded to the first cycle of RTX treatment with improvements in muscle enzyme and muscle strength, and then maintained physical function over the duration of several infusion cycles. In one patient, muscle enzyme did not decrease after the first cycle of RTX, and a high dose glucocorticoid was given. After modifying the treatment schedule with monthly RTX infusion, his muscle enzyme level and muscle strength improved. Anti-CD19 antibody decreased after RTX generally, but responses were variable. Herpes zoster infection occurred in two patients. Conclusion. Rituximab may be a therapeutic choice in refractory inflammatory myopathy. However a further trial is needed to confirm the efficacy and prove the safety.

We report a 38-year-old Korean female diagnosed with (tubulointerstitial nephritis and uveitis syndrome. The patient was hospitalized because of an elevated level of serum creatinine with persistant nausea. Blood tests revealed renal insufficiency and a renal biopsy revealed acute tubulointerstitial nephritis. Four days after admission, the patient developed a conjunctival injection in the left eye and slit-lamp examination revealed anterior uveitis. The patient was diagnosed with tubulointerstitial nephritis and uveitis syndrome and was treated with systemic and topical steroids.

The purpose of this study is to investigate experimentally the mechanical characteristic of T-shaped wall in wall slab system apartment buildings considering effective width in flange. Currently all walls of apartment buildings are designed as uniform rectangular wall. Thus the effect of wall which is perpendicular to applied lateral load is ignored resulting excessive reinforcement in web. We made the three walls as specimens were full scale and cyclic lateral loads were applied at the top of the walls. Also We performed Nonlinear analysis of FEM method to compare with the results of the experiment and to give a basic informations to parameter research. The test results indicated that it is possible to design shear walls economically if structural roles of vertical reinforcements within effective width of flange are considered.

본 연구의 목적은 유치원 교사의 유초연계교육 교수역량 증진을 위한 교사연수 프로그램을 개발하는 것이다. 이를 위해 ADDIE 모형에 근거하여 분석단계, 설계 단계, 개발 단계, 실행 단계, 평가 단계를 거쳐 프로그램 최종안을 개발하였다. 분석단계에서는 관련 문헌고찰, 전문가 심층면담, 현직교사 설문조사를 통해 프로그램에 대한 요구를 조사한 후, 이를 바탕으로 설계 단계에서는 프로그램의 시안을 구성하였다. 개발단계에서는 전문가 타당도를 검증받아 프로그램을 시안을 수정하였고, 실행단계에서는 ‘현장으로 찾아가는 수요자 중심의 맞춤형 교사연수’를 지향하는 본 프로그램의 특성을 고려하여 프로그램 참여자들의 요구를 반영하여 프로그램을 실행하였다. 평가 단계에서는 실행 단계에서 수집한 자료를 분석하여 프로그램의 현장적합성과 타당성을 확인하였고, 그 결과를 반영하여 프로그램 최종안을 확정하였다. 유치원 교사를 위한 유초연계교육 교사연수 프로그램은 ‘계속성/연속성 개념으로 접근하는 유초연계교육’, ‘유초연계와 관련된 유아의 감정에 공감하는 학습자 중심의 교육’, ‘현장으로 찾아가는 수요자 맞춤형 연수 과정’, ‘다양한 참여형 교수학습전략 사용’, ‘유아교육 전문가와 초등교육 현장전문가가 함께 연수 운영’이라는 기본방향에 맞춰 프로그램의 목적 및 목표, 교육내용, 교수학습방법, 평가, 운영방법으로 이루어져 있다. This study aims to develop a teacher training program that is designed to improve kindergarten teachers’ teaching competence for educational continuity between kindergarten and elementary school. The program was developed with ADDIE model development process. In the “analysis” phase, the researcher conducted literature reviews of the related topics, investigated and analyzed demands for this program through an in-depth interview with experts and a survey of in-service teachers. In the “design” phase, a draft proposal of the program was composed, which reflected the demands examined in the “analysis” phase. In the “development” phase, the draft proposal of the program was modified through considering the results of the validity by experts. In the “implementation” phase, the researcher implement the program to reflect the needs of the program participants. In the “evaluation” phase, the data from the implementation phase was analyzed and was identified the on-site suitability and validity of the program. Reflecting the evaluation results, the final version of the kindergarten teacher training program was confirmed. The directions of the program development are “educational continuity between kindergarten and elementary school which approaches with the concept of the continuity”, “the learners-centered education empathizing with children’s emotions related to the continuity between kindergarten and elementary school”, “the consumer-customized training course by visiting the site”, “the use of various participatory teaching-learning strategies”, and “the operation of training by experts in early childhood education and on-site experts in elementary education”.

Entomopathogenic fungi have the most important role as biological control agents, and there are so many distributions that 100 genera and 750-1000 species are reported worldwide. The main route of entry of fungi is through the epidermis of insects or penetrates and infects through wounds or organs. Entomopathogenic fungi are most widely belong to Ascomycota, and the main genus are Beauveria, Metarhizium, Isaria, Paecilomyces, and Cordyceps. And as a species of these genera, it can be used to control pests. It is used in various ways in Korea and abroad, and there are Chongchesak, Chongjinshak, and Baekgangtan in Korea, and Mycotrol, Botanigard, and Met52 abroad.
