This work discusses the major roles of digital technologies in the history of landscape architectural drawing, and offersa critique of the dominant trend towards realism in recent digital landscape representations. During the period of transitionfrom conventional drawing tools, computer technologies generally functioned as mechanical tools to imitate prior manualtechniques. Specifically, the GIS was served as a mechanical tool to efficiently process the manual layer cake; CAD softwaregenerally functioned to translate physical models to two-dimensional construction documents while graphic software generallyfunctioned as a tool to perform processes similar to those of manual collage and montage techniques. Recent digital landscape drawings tend to adopt a realistic depiction like the painting of landscape appearance. In therepresentations, discernible traces of cutting and assembling are removed via graphic software; thus, the completerepresentations are perceived as if they were a copy of an actual landscape. The realistic images are an easy way tocommunicate with the public. However, it is difficult to achieve a full embodiment of all of the multisensory characteristicsof a landscape through these visuals. They often deceive viewers by visualizing idealized conditions of not-yet-actualizedlandscapes and production of the final images takes up a large portion of the overall design process. Alternatively, 3Ddigital modeling of landscape performance and creative uses of digital technologies during the overall design process, aswell as hybridized techniques with different drawing techniques and technologies, provide the opportunity to explore variousaspects of a landscape. 이 연구는 지금까지 조경 드로잉에서 컴퓨터 테크놀로지가 어떠한 역할을 해왔는가를 검토하고, 근래의 디지털드로잉에서 발견되는 사실적 묘사 경향에 관한 쟁점을 진단한 후 대안적 방향을 모색한다. 조경 드로잉의 매체가 손에서컴퓨터로 이행하는 시기에 드로잉 테크놀로지는 대체로 손 드로잉의 테크닉을 모방하는 기계 도구의 기능을 담당했다. GIS는 레이어 케이크의 절차를 보다 정확하게 효율적으로 처리했고, CAD는 물리 모형을 시공 도면으로 변환했으며,그래픽 소프트웨어는 콜라주와 몽타주를 보다 쉽게 만들 수 있도록 도왔다. 근래에 디지털 조경 드로잉에는 경관의 외양을 회화와 같이 사실적으로 묘사하려는 경향이 짙다. 그래픽 소프트웨어를 이용하여 사진 재료의 조립 흔적을 지워내 마치 실재 경관을 포착한 사진처럼 보이도록 제작되고 있다. 이러한 사진과같은 이미지는 대중과의 의사소통에 수월하지만, 경관의 다감각적 특성을 온전하게 구현하기 힘들고, 좀처럼 현실에서발생하기 힘든 경관의 가장 이상적인 순간을 묘사하여 수용자를 기만하는 경우가 발생하기도 하며, 자칫 최종 결과물처럼여겨져 드로잉의 생산에만 집중하게 할 우려가 있다. 이에 대한 대안적 방향으로, 경관의 기능 정보를 삼차원으로 모델링하고, 디지털 테크놀로지를 설계 전반 프로세스에서 설계 아이디어를 발전시키는데 활용하며, 서로 다른 드로잉 테크닉과테크놀로지를 혼용하여 경관의 다양한 국면을 시각화하는 실험이 필요하다.
Reconstruction Techniques for Tissue Defects Formed after Preauricular Sinus Excision
이명준,양호직,김종환 대한성형외과학회 2014 Archives of Plastic Surgery Vol.41 No.1
Background: Preauricular sinuses are congenital abnormalities caused by a failure of fusion of the primitive tubercles from which the pinna is formed. When persistent or recurring inflammation occurs, surgical excision of the infected tissue should be considered. Preauricular defects inevitably occur as a result of excisions and are often difficult to resolve with a simple suture; a more effective reconstruction technique is required for treating these defects. Methods: After total excision of a preauricular sinus, the defect was closed by a plastic surgeon. Based on the depth of the defect and the degree of tension when apposing the wound margins, the surgeon determined whether to use primary closure or a posterior auricular flap. Results: A total of 28 cases were examined. In 5 cases, including 2 reoperations for dehiscence after primary repair, reconstruction was performed using posterior auricular transposition flaps. In 16 cases of primary closure, the defects were closed using simple sutures, and in 7 cases, closure was performed after wide undermining. Conclusions: If a preauricular defect is limited to the subcutaneous layer and the margins can be easily approximated, primary closure by only simple suturing may be used to perform the repair. If the defect is deep enough to expose the perichondrium or if there is tension when apposing the wound margins, wide undermining should be performed before primary closure. If the extent of the excision exposes cartilage, the procedure follows dehiscence of the primary repair, or the tissue is not sufficiently healthy, the surgeon should use a posterior auricular flap.

Many methods for early diagnosis of the cancer are using biomarkers, measuring indicators of some biological state. However, there is no proper detection kits because of low sensitivity and specificity of the biomarkers. This problem can be solved if very small amount of them can be detected effectively. Therefore, we have developed human albumin-based nanoparticle that encapsulates an excess of horseradish peroxidase (HRP) which is used extensively for ELISA assay. If it is applied to complementary principle of antigen-antibody reaction, it shows higher optical signal than many HRP-conjugated antibodies commercialized on the market. More specifically, it is detectable from 10fM to 1nM range of the probe. As a result, this research verifies that this albumin nanoparticle containing excess HRP enhances signal strength of probe detection contributing to more accurate and early diagnosis for breast cancer.

The purpose of study is to evaluate appropriateness of using low-e glazing for each frame to resist condensation on window. Also, it is to show a methodology to figure out how serious the condensation is going to be made through algorithm by weater data in apartment houses with condensation occurrence. Recently, many units in apartment try to extend the area of their own unit by extending their balcony in unit. Because the area of extended balcony has reasonably low mean radiant temperature due to lack of insulation, it causes one of the serious problem which is condensation. In our study, normal double glazing and Low-E coating double glazing has been applied to three kinds of frames, and the temperature has been measured by numerical method of simulation and experiment. To check the degree of efficiency of condensation, Seoul weather data has been used to count the hour that occurred condensation and then made the ratio of condensation for all windows. Consequently, frame with Low-e coating glazing has good performance to resist condensation a lot more than frame with the normal double glazing has.

목적:요로폐색 환자와 요로폐색이 없는 정상인에서 요로계를 평가하는데 생리 식염수와 이뇨제를 이용한 약물 유도 자기공명 요로조영술의 유용성을 알아보고자 하였다. 대상과 방법:요로폐색이 있는 12명의 환자(요로결석 8명,요관 외부종괴 1명,종양에 의한 요관침범 3명)와 정상 자발군 3명을 대상으로 하였고 1.0T 기기를 이용하여 호흡정지 없이 급속 스핀에코의 강한 이차원적 T2 강조기법으로 자기공명 영상을 얻었다.이 과정은 최대 신호 투영법을 사용하였다.자기공명 영상은 2가지로 얻었다.첫 번째는 생리 식염수와 이뇨제(Lasix)를 정맥주사 하기 전에 자기공명 요로조영술을 시행하여 표준 자기공명 요로조영상을 얻었다. 두번째는 생리 식염수 250 ml를 2-3분에 걸쳐 정맥주사 직후 Lasix 20 mg을 정맥주사하여 약물 유도 자기공명 요로조영상을 얻었다. 결과:정상 자발군 3명과 요로결석에 의해 부분 요로폐색이 있던 4명에서는 약물유도 자기공명 요로조영술이 표준 자기공명 요로조영술보다 요로에서 영상의 질이 좋았다.요로결석이나 종양에 의해 심한 요로폐색이 있던 8명에서는 표준 자기공명 요로조영술이 약물 유도 자기공명 요로조영술과 같이 좋은 영상을 나타냈다. 결론:약물 유도 자기공명 요로조영술은 요로폐색이 없거나 부분 요로폐색이 있는 환자의 해부학적,기능적 평가에 유용하였다.그러나 요로폐색이 심한 경우 표준 자기 공명 요로조영술이 요로를 잘 평가할 수 있었기 때문에 약물 유도 자기공명 요로조영술은 필요하지 않으리라 사료된다. Purpose: To determine the usefulness of MR urography technique for the evaluation of urinary systems in patients with obstructed urinary tract and normal volunteers with non-obstructed urinary tract after intravenous normal saline and diuretic injection. Materials and Methods: Three normal volunteers and 12 patients with urinary tract obstruction [ureteral calculi( n=8), extraurinary mass(n=1), ureteral tumor invasion(n=3)] underwent MR urography using a 1.0T scanner and a 2D non-breath-hold heavily T2-weighted fast spin-echo sequence. These acquisition were post-processed with a maximum intensity projection (MIP) algorithm. Two acquisitions were performed, the first prior to saline solution infusion following standard MR urography procedures, and the second, within 2 -3 minutes of the infusion of 250 ml saline solution followed by 20 mg of Lasix administered intravenously. For this latter, drug-induced MR urography procedures were followed. Results: In healthy volunteers (n=3) and those experiencing partial obstruction (n=4) by a urinary stone, drug-induced MR urography provided better images of the urinary tract than did standard MR urography. In those in whom a urinary stone or tumor had caused complete obstruction (n=8), standard MR urography provided good images, as did drug-induced MR urography. Conclusion: In patients with a partially or non-obstructed urinary tract, drug-induced MR urography provided better anatomic and functional details of the kidney and urinary tract than did standard MR urography. In those experiencing complete obstruction of the urinary tract, however, standard or drug-induced MR urography permitted very adequate evaluation of the tract, and drug-induced MR urography was unnecessary.
