본 연구에서는 3절점 요소와 4절점 요소를 가지는 비등방성 절판 구조물의 처짐 해석을 수행한다. 절판 구조물을 해석할 때 4절점 요소뿐만 아니라 3절점 요소의 사용이 필요한 경우가 발생하게 된다 그러나 3절점 요소를 사용하는 것은 간단하지 않다. 그러므로 본 연구에서 사용한 3절점 요소는 4절점 요소에서 절점을 감소시키는 방법을 사용하여 계산 과정의 편의성과 3절점 요소의 사용으로 인한 복잡성을 피할 수 있다. 이러한 방법을 고차 전단변형이론에 적용하기 위하여 Lagrangian 보간함수만을 사용한다. 또한 해석과정의 편의성 및 정확성을 위하여 면내회전각 자유도를 도입한다. 특히 본 논문에서는 3절점 및 4절점 요소의 사용에 의한 비등방성 복합적층 절판 구조물의 거동 특성을 분석하며 이에 대한 영향을 다양한 매개변수를 통하여 상세히 규명하고자 한다.

폐의 편평상피암종에서 기관지표면상피의 화생에 대해서는 많은 이들에 의해서 밝혀진 바 있지만 그 외의 다른 종류의 폐암과 연관된 기관지 표면상피의 변화에 대해서는 그 예가 많지 않고 소세포폐암종에 대해서는 더욱 그러하다. 한편 소세포암종의 조직학적 분류와그아형에 대해서 지난수십년 간많은 관심이 모아져 왔다. 이 종량의 아형을분류하는기본적인 근거는 그 형태학적 판정 기준에 있다. 1967년 WHO폐암종 분류법이 제긍된 이후 3여러 기관에서 SCLC의 임상경과나 치료에 대한 반응, 그 아형을 연구하였다. 1988년 IASLC에서는 소세포암종을 그 형태학적 구분으로 세가지 아형 : Small cell carcinoma (2) Mixed small cel1/1arge ceil carcinoma (3) Combined small cell carcinoma로 분류하고 예후와 치료에 대한 반응의 차이에 대해서 언급하였다. 최근 저자들은 68세 남자환자에서 소세포암종에서 국소적으로 편평양분화를 보이는 세포가 함께 혼합되어 있는 주종괴와 분리되 어서 존재하는 기관지 상피세포에 편평상피암종이 동반된 예를 전폐 절제 술을 하고 조직 검사상 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Nanocrystalline Fe-Sm-O thin films were prepared by RF magnetron reactive sputtering method in $Ar+O_2$mixed atmosphere with the $O_2$content of 5%. The compositions of the thin films were changed by changing the number of $Sm_2O_3$ chips. The best soft magnetic properties of the thin film with the composition of $Fe_{83.4}Sm_{3.4}O_{13.2}$ were saturation flux density of 18 kG, coercivity of 0.82 Oe and effective permeability about 2,600 at 0.5~100 MHz, respectively. The electrical resistivity of Fe-Sm-O thin films was increased with increasing the amount of Sm and O elements which combined each other, the electrical resistivity of$Fe_{83.4}Sm_{3.4}O_{13.2}$ thin film was $130{\mu}{\Omega}cm$. In case of the small amount of Sm and O elements, the microstructures of Fe-Sm-O thin films showed a precipitated phase of $Sm_2O_3$ on the ${\alpha}-Fe$ phase. With the increase of the amount of Sm and O elements, the microstructures of the Fe- Sm-O thin films were changed into a mixed structure of ${\alpha}-Fe$ crystal-phase and Sm-oxide amorphous phase. The Fe-Sm-O thin films with Fe content in the range of 72~94 at% exhibited the quality factor (Q = $\mu$′/$\mu$") of 7~75 up to 50 MHz.

The purpose of this study is to develop Korean clothing designs that can satisfy future consumer's needs based on the elements extracted through the content analysis method in a study on the design elements expressed in traditional outfits in the 2010s. To this end, data analyzing Hanbok in wedding magazines were used, and after extracting design elements, research methods for empirical design development were used. After subclassifying the major design elements, factors with a steady increase in frequency and appearance rate were identified. Through this, five elements capable of aesthetic sampling were extracted by complex expression methods and expressed in a total of seven combinations. The types extracted from the design elements are items, silhouette, top shape, skirt shape, skirt length, mixed items with increasing frequency. In the element of color, the adjacent color harmony, which showed the highest frequency of color, and the white-blue harmony, which showed an increase among them, were extracted. When using materials, top and skirt have similar usage rates of the same and different materials, so both contents were extracted, and many patterns were arranged in the top and the whole, but these three were extracted because there were increasing cases where there were no patterns. In the case of decoration, embroidery, pintuck, sakdong, applique, lace, ribbon on the top, silver foil and print on the skirt were extracted. Through this study, it was possible to propose a future Korean costume design model.

High-rise mixed-use buildings are consisted of various facilities and circulations. Since various facilities and circulations are planned in a single site, circulation planning should be established after identifying the exact characteristics of facility and circulation. To this end, the components of the circulation planning in accordance with the formation of facility types are analyzed through the survey of experts based on Delphi Method. To identify the characteristics of the mixed-use buildings, by figuring out how the elements of circulation planning which are sought to be important by the planner has been reflected through analysis of the correlation between two sections. Researching on the circulation between two sections through Delphi Method and reflected circulation planning, it reaches the conclusion that the circulation of planning on the subject building is applied following the importance. In other words, the components of circulation planning which were sought to be important by the planner are reflected significantly when they planned the circulation planning on that mixed-use buildings. However, in case of design on the outdoor vehicle circulation, minimizing on the vehicle circulation at the 1st floor is not applied for the majority of the subject buildings different from the importance. In early 2000, high end residential buildings designed for mixed-use building have been specialized at vehicle-centered outdoor space and hotel style drop-off. Contrastively, sizable outdoor space at the 1st floor is designed to open to the residents and the local by minimizing the vehicle circulation in recent. Finally it shows that the way of circulation planning has been changed in accordance with time and trend.
