남진영(2008a)은 학생의 수학적 구조의 학습을 돕기 위한 교사의 역할을 암묵적 지식의 현시자라고 제안하였다. 그러나 아직 암묵적 지식의 현시의 의미를 구체화한 연구는 부족하다. 이에 본 연구에서는 Watson & Mason(2015)의 제안한 예 구성 활동이 그 목표, 내용, 방법 면에서 암묵적 지식을 현시하는 한 가지 방식임을 보임으로써, 암묵적 지식의 현시의 의미를 구체화하고자 하였다. 첫째, 예 구성 활동을 통한 암묵적 지식의 현시는 암묵적 영역에 있는 수학적 구조의 학습을 목표로 한다. 둘째, 예 구성 활동을 통한 암묵적 지식의 현시는 예를 통해 변이 속에서 불변적인 요소를 인식함으로써 암묵적 영역에 있는 수학적 구조를 교육하고자 한다. 셋째, 예 구성 활동을 통한 암묵적 지식의 현시는 명시적 지식을 창의적으로 구성해보는 활동, 활동에 대한 반성 과정, 사회적 상호작용을 통해 암묵적 영역에 있는 수학적 구조를 교육하고자 한다. 따라서 예 구성 활동은 그 목표, 내용, 방법 면에서 암묵적 지식을 현시하는 구체적인 한 수업 방식으로 볼 수 있다.

The visceral manifestation theory in the "Hwangjenaegyeong(黃帝內經)" was constructed by the reference of the study of Confucian classics which main characteristics is the extensive application of the five phase theory. "Image" plays an important role in the thinking of the Chinese ancient people and it is the basis of the construction of the visceral manifestation theory. "Concept of holism" is the main directed thinking of the "Hwangjenaegyeong(黃帝內經)" "Four seasons, five viscera, Yin yang" theory is the core contents of the visceral manifestation theory in the "Hwangjenaegyeong(黃帝內經)".

본 연구는 수학영재의 집단창의성 발현 모델을 이론적으로 구안하고, 이를 실제 수업에 적용한 결과를 분석하여 모델을 확인하고 정교화하는 것을 목적으로 한다. 영역 일반적인 집단창의성에 대한 선행연구와 수학영재의 창의성에 대한 선행연구를 고찰하여 집단창의성 발현 모델을 구안하였다. 또한 이 모델을 수학영재학급 수업에 적용하여 학생들이 보인 반응을 분석하였다. 분석 결과, 집단창의성 발현 모델의 각 단계에 따른 수학영재의 반응과 집단창의성에 작용하는 주요 요인을 확인하였으며, 수학적 정당화를 위해 추측 또는 문제해결 아이디어 공유 단계로 되돌아가는 과정과 집단 수준의 창의적 시너지가 일어날 수 있는 발생 및 긴장 상태에서 추측 또는 문제해결 아이디어 공유단계로 되돌아가는 과정을 추가적으로 발견하였다.

This study was operated to establish induction using ultrasonography by estimating the relation of follicle size and estrus manifestation. Clinical estrus symptoms were observed 97.4% in cows and 87.5% in heifers when overall 55 cows were induced to estrus in a single dose of $PGF_{2{\alpha}}$ after verifying CL through ultrasonography, which means estrus hours among those 52 cows showing the clinical estrus symptoms were estimated 2.39 days on cows and for 2.37 days on heifers which showed no differences (p>0.05). The estrus manifestation hours according to the follicle size in cows didn't have any significance each other (p>0.05), though estrus hours was 54 hours (the shortest) with follicle size bigger than 10 mm and were made up within 69 hours. The estrus manifestation hours according to the follicle size in heifers didn't have any significance each other (p>0.05) and took around 42 hours (the shortest) with follicle size of 5mm (the smallest) and were made up within 66 hours. Follicles after $PGF_{2{\alpha}}$ injection were ovulated and assigned to many phases as follows; Group 1 (growing phase) - continuously growing into ovulation, Group 2 (growing and static phase) - delaying in growth after the growth of follicles, Group 3 (static and growing phase) - growing after growth delay, Group 4 (regressing and new growing phase) - the follicle is closed and a new follicle grows. In addition, the process of follicle development and estrus hours had no significance each other (p>0.05), though estrus manifestation hours in Group 1 and 2 was relatively short, and in Group 3 and 4 for a relatively long time. In the result of all above, the estrus manifestation hours after $PGF_{2{\alpha}}$ injection has no differences accoring to the follicle size in cows and heifers. Therefore, High pregnancy rate is obtained when practicing artificial insemination within 3 days in estrus or TAI in 72 to 80 hours after adminitrating $PGF_{2{\alpha}}$.

Purpose: This report describes a case of granulomatosis with polyangiitis (GPA) in which the gingival manifestation was crucial in both making an early diagnosis and possibly in deciding the approach to treatment. Methods: A 57-year-old sailor presented to the Department of Dentistry at Ulsan University Hospital complaining of gingival swelling since approximately 2 months. He had orofacial granulomatous lesions and the specific gingival manifestation of strawberry gingivitis. Results: The diagnosis of GPA was made on the basis of clinical symptoms and signs, and confirmed by the presence of the anti-neutrophil cytoplasmic antibody and a positive biopsy. The patient was admitted to the hospital and subsequently placed on a disease-modifying therapy regimen that included methotrexate and prednisone. Conclusions: Identification of the gingival manifestation of the disease permitted an early diagnosis and prompt therapy in a disease in which time is a crucial factor. Because of its rapid progression and potentially fatal outcome, an early diagnosis of GPA is important. Therefore, dentists should be aware of the oral signs and symptoms of such systemic diseases.

This experiment was performed to examine the in vitro and in vivo affects of the two different haplotype strains of mice, BALB/c and C3H/HeN infected with Echinostoma hortense, and the manifestation of the profiles of cytokine in the splenocytes. In the in vitro experiment, the two mice's splenocytes were divided and stimulated with antigen of crude extracts and the antigen of excretory and secretory products of an adult warm and the manifestation of cytokine mRNA was verified with RT-PCR. As a result, the two different strains of mice both strongly manifested the Th2 cytokine rather than the Thl cytokine and in the case of the Th2 cytokine, the BALB/c mice manifested more strongly than the C3H/HeN mice. In the experiment using the ELISA method, the protem cytokine manifestation had the same result as the mRNA experiment. In the in vivo experiment, the mice was infected via oral route with the metacercaria of the Echinostoma hortense and the manifestation of cytokine was verified by RT-PCR and ELISA and the results were the same as the in vitro experiment. Therefore, in the two strains of BALB/c and C3H/HeN, the C3H/HeN showed a higher susceptivity to the Echinostoma hortense.

서지환경이 링크드 데이터, 시맨틱웹 기반으로 전환됨에 따라 국내에서도 RDA를 기반으로 한 KCR5 개정 작업을 진행 중에 있다. 변화하는 서지환경에서도 전거형 접근점은 자원의 식별 및 자원 간의 연계에 중요한 역할을 하고 있으나, KCR5가 준용하는 원본 RDA는 모든 개체에 대한 전거형 접근점이 마련되지 않은 상황이다. 이에 본 연구에서는 RDA 2020의 구현형의 전거형 접근점 분석을 토대로 국내 서지환경 및 원본 RDA에 적용 가능한 구현형의 전거형 접근점의 속성을 선정하고 연계 구조를 제안하였다. 구현형의 전거형 접근점은 지적 측면과 물리적 측면을 모두 고려한 접근점으로, 실제 자원의 연계와 식별이 더욱 원활해지는 토대를 마련할 수 있다. 또한 국내 서지환경에 적합한 구현형의 전거레코드 연계 구조 구성은 향후 구현형의 전거형 접근점의 실제적인 적용에 도움이 될 것으로 기대된다.

Visual loss is one of the ocular symptoms resulting from a carotid cavernous fistula (CCF), but has rarely been reported as the sole manifestation in CCF. Visual impairment is known to be associated with a poor outcome unless timely intervention is employed. Herein, the authors report a patient with bilateral rapid progressing visual loss as a sole manifestation in CCF. Vision was successfully restored by transarterial embolization. The authors discuss the necessity of urgent fistula obliteration in patients with visual loss.

IgA nephropathy usually presents as asymptomatic microscopic hematuria or proteinuria or episodic gross hematuria after upper respiratory infection. It is an uncommon cause of end-stage renal failure in childhood. Pulmonary hemorrhage associated with IgA nephropathy is an unusual life-threatening manifestation in pediatric patients and is usually treated with aggressive immunosuppression. Pulmonary hemorrhage and renal failure usually occur concurrently, and the pulmonary manifestation is believed to be caused by the same immune process. We present the case of a 14-year-old patient with IgA nephropathy who had already progressed to end-stage renal failure in spite of immunosuppression and presented with pulmonary hemorrhage during oral prednisone treatment. His lung disease was comparable to diffuse alveolar hemorrhage and was successfully treated with plasmapheresis followed by oral prednisone. This case suggests that pulmonary hemorrhage may develop independently of renal manifestation, and that plasmapheresis should be considered as adjunctive therapy to immunosuppressive medication for treating IgA nephropathy with pulmonary hemorrhage.
