수학 교실에서 학생들은 교사나 동료 학생과의 의사소통을 통하여 수학적 지식을 구성하고, 서로의 지식을 타인과 교환하게 된다. 그런데 수학 학습의 주요 과정이 문제해결 활동임을 고려할 때, 학교 수학에서 다루어지는 어떤 문제 유형이 수학적 의사소통을 촉진시키는가를 알아보는 것은 중요하다. 이를 위해 본 연구에서는 수학 문제유형을 정형-개념형 문제, 정형-절차형 문제, 비정형 문제, 실생활 문제로 구분하여 소집단 문제해결 과정에서 구성원들의 의사소통 패턴을 분석하였다. 연구 대상자로 초등학교 4학년 8명의 학생을 선정하여 2개의 소집단으로 구성하였고, 2개의 소집단이 각각 5시간에 걸쳐 4가지 문제 유형으로 구성된 5세트의 문제를 해결하였다. 결과 분석을 위해 소집단 문제해결 과정을 비디오로 녹화하여 전사한 자료와 관찰일지, 문서자료를 이용하였다. 그 결과, 비정형 문제와 같은 문제해결 방법이 다양한 문제일수록 소집단 구성원들의 수학적 의사소통 참여도가 높았다. 또한 비정형 문제에서 다양한 풀이 방법에 대한 논의 및 새로운 풀이 전략에 대한 아이디어 공유와 같은 다수 참여의 의사소통 패턴이 나타났고, 수용적 합의, 논쟁적 합의, 정교화된 합의 등 다양한 합의 패턴이 나타났다.

본 연구에서는 비정형 패널 제작 기술력 향상을 위한 기초적인 연구로 비정형 패널의 오차율을 분석하였다. 이에 본 연구에서는 우선적으로 비정형 패널 제작시 매끄러운 형상을 표현하기 위해 콘크리트 대신 혼합모르타르를 사용하여 적정 배합비를 도출하였다. 그 후 도출한 배합비를 적용하여 비정형 패널을 CNC장비를 통해 제작하였으며 패널의 오차율을 분석하였다. 본 연구에서는 두 가지의 배합을 선정하였으며 선정한 첫 번째 배합은 혼합시멘트 페이스트 배합, 두 번째 배합은 혼합모르타르 배합이었다. 실험결과 두 배합모두 품질적 측면에서 만족하는 정량적 수치를 보였다. 하지만 두 배합모두 양생하는 방법에 차이를 두었고 이로 인해 오차가 발생했다. 이를 통해 오차율은 사용재료의 특성과 재료 간 화학반응의 문제보다는 패널을 양생하는 방법에 따라 더 많은 영향을 끼치는 것으로 판단하였다. 본 연구는 현재 기초적인 연구수행으로 추후 본 연구를 토대로 추가적인 연구를 진행한다면 콘크리트 타설시 흘러내림을 방지하는 방안과 오차율을 줄일 수 있는 양생방법을 찾는 연구가 함께 병행되어야 한다. 위와 같은 연구수행을 통해 비정형 패널 제작에 대한 연구 및 개발에 기여할 수 있으며 나아가 비정형 건축시장에서 경쟁력을 확보할 수 있다.

This study examines the morphological expression type and formative characteristics of women's shoes designs that integrate 3D printing technology. The results of the study are as follows. First, the morphological expression types of contemporary shoes that integrate 3D printing technology express a structural form created by repetition. Second, it expresses a dynamic form, which combines organic curves that create an external volume. Third, it expresses a surrealistic form centered on an object with the creation of a unique shape that utilizes objects easily experienced in local surroundings. Fourth, it expresses a hybrid form on a partial derivation. Each of the other system's components are fused to create another beauty that develops a new value in a colorful variation on the shape of 3D printing shoes. The first formative characteristic of women's shoes designs that integrate 3D printing technology is continuity. This creates an invisible form of a new space through repetitive unidirectional layers with a gradual expansion of a unitary seamless curves. Second, it is an exaggeration. This exaggeration elicits an enormous aesthetic quality by structuring the outward space in the difference of the volume formed based on the maximization of a specific part and the volume of a line's atypical movement. Third, it is a decoration. It displays the beauty of a decoration that evokes a unique artistic inspiration by partial unification or a practical representation of a specific form. This can also be seen as superimposing a 3D printing figure that has an outstanding shape onto part of the fashion shoes. Fourth, it concerns a geometrical characteristic that formulates a new structure with rationality in combining basic shapes such as circles, triangles and squares with lines, hexagons and interconnected geometrical forms to create a multi-dimensional space for shoes in a systematic and unidirectional pattern.

Apocrine carcinoma is a rare form of breast malignancy and is composed of entirely or predominantly of apocrine type epithelial cells. Apocrine metaplastic cells are frequently noted in fine needle aspiration cytology(FNAC) of breast lesions, especially fibrocystic disease. These apocrine cells may occasionally be atypical, to make a diagnostic difficulty. Two cases of apocrine carcinoma of the breast diagnosed by FNAC are described, and differential cytologic points between apocrine metaplasia and apocrine carcinoma are discussed. The first case is a right breast mass of a 37-year-old woman for 20 days. The smears show many single or sheets of large cells on bloody background. Each cell has a large vesicular nuclei with multiple macronucleoli and abundant eosinophilic granular cytoplasm. The second case is a left breast mass of a 35-year-old woman for one month. The smears show similar findings as seen in the first one. Histopathologic findings of both cases are typical of apocrine carcinoma. Electron microscopy demonstrates variable numbers of large osmiophilic granules in diameter of $200\sim600nm$ in both cases.

This work surveys the trend and dissolution characteristics in headdress that appear in Jean Paul Gaultier's collection. Along with a related literature review, a total of 903 headdress pieces shown in collections 40 times (excluding the common caps and hats) were analyzed, covering from 2001S/S to 2010 F/W of Jean Paul Gaultier's Haute Couture and Pret-a-Porter. The headdress trend indicated in his collections was divided into such subgroup forms of folklore, usage of natural things, usage of artificial things, religion, retro, scarf, variations in headgear, mask and veil, atypical type and abstract. Such an expression tendency was so unique and mixed characteristic that it was hard to define its form and structure thanks to enlargement and exaggeration, extremity in ornaments, and use of foreign materials, which led to creative dynamics. Gaultier's headdress also reflected the following characteristics: first, expression of difference indicative of time deconstruction; second, uncertainty of meanings via deconstruction; third, text interactivity via deconstruction of gender and material adopted; fourth, decentralization through dissolution of the Orient and the Occident.

The purpose of this study is to investigate the concept and characteristics of 'grotesque,' examine the aesthetic characteristics of grotesque reflected in arts and dress, and modern fashion. The findings are as follows: 1) Grotesque indicates unnatural, unpleasant, and exaggerated that it upsets or shocks person. The characteristics of grotesque include terror, abnormality, unreality, amusement, disgust. 2) The grotesque art represented terror, abnormality, unreality, amusement, disgust by disordered form, nonnatural things, evil world, unorthodox methods, unrealistic image, strange dreamland. 3) The grotesque dress represented terror, abnormality, unreality, amusement, disgust by exaggerated silhouette, exaggerated adornment, excessive decoration, incroyables, using exaggerated silhouette, crinoline silhouette, bustle silhouette, surrealist style, extraordinary materials, glam rock style, unique silhouette, cyber look. 3) Terror was implied in the punk look suits of Junya Watanabe, and exaggerated outers of Viktor & Rolf. Abnormality was shown in the atypical suit of John Galliano, Junya Watanabe's dress decorated with the extreme ruff, Thom Browne's suit of abnormal proportion. Unreality was reflected in the architectural dress of Gareth Pugh, Mermaid dress of Giles, the surreal suit of Jean-Charles de Castelbajac. Amusement was represented in the amusing suit of Gareth Pugh, John Galliano's dress of sexual perversion. Disgust was reflected in the decadent dress of Thierry Mugler, Undercove's suit, and the ensemble of shocking details.

A five-month-old, male Domestic Korean shorthair was referred to our hospital with a history of lethargy, anorexia, and globoid cardiac silhouette on thoracic radiography. Physical examination showed dehydration and anemia was revealed on blood analysis. On thoracic radiography and echocardiography, the patient showed pericardial effusion and ultrasound-guided pericardiocentesis was performed. A Rivalta test of the pericardial effusion showed a positive result. As the patient had recurrent pericardial effusion, pericardiectomy was performed. He was tentatively diagnosed with wet form feline infectious peritonitis (FIP) and treated with Polyprenyl immunostimulant (PI). Neurological signs were eventually seen and he was euthanized. Histopathologic changes with markedly expanded neutrophils, lymphocytes, plasma cells, and macrophages with fibrous connective tissue and collagenous fibers were detected. Immunohistochemistry for FIP antigen was performed and results showed FIPV-positive multifocal aggregates of cells. Pericardial effusion is an atypical condition in cats with FIP, but can be presented. This case report describes FIP with pericardial effusion in a cat, in which definitive diagnosis of FIP was done using biopsy via pericardiectomy.

The lung is one of the most frequent sites of metastasis for extrathoracic tumors. Certain malignancies show a particular tendency to metastasize to lung, and in 15 to 25% of these cases, lung involvement is the only manifestation of metastatic disease. The most common presentation is the form of multiple bilateral nodules or masses of varying sizes. Lymphangitic metastasis is comprising 6 to 8% of all pulmonary metastasis. A striking variant of parenchymal involvement occures when dyscohesive tumor cells fill alveoli to produce a tumoral pneumonia. Carcinomatous lymphangitis of prostate origin is infrequent and usually carries a poor prognosis, and tumoral pneumonia of it is extremely rare. We report herein a case of prostate carcinoma metastasizing to lung, simulates atypical pneumonia, and disclosed by acute chest illness.
