Purpose : The purpose of this study was to evaluate the diagnostic accuracy of 3.0-T breast MRI for detecting additional breast cancer soon after the initial diagnosis of breast cancer. Materials and Methods : From March to June 2009, 101 patients recently diagnosed breast cancer underwent breast MRI and surgery. Parameters analyzed on MRI were total extent of tumor, suspicious findings of multifocal, multicentric, or contralateral cancer. The diagnosis of MRI-detected cancer was confirmed by means of biopsy or surgical specimen evaluation after the localization. Results : MRI showed 37 additional suspicious findings in 34 patients. Twenty nine findings were true-positive (29/37, 78.4%), including 16 cases of multifocality, 11 cases of multicentricity and 2 cases of contralateral cancer. Among these cancers, 13 (44.8%) were ductal carcinoma in situ (DCIS) and 16 (55.1%) were infiltrating cancer. Eight findings were false-positive (8/37, 21.6%) including 6 cases of benign disease and 2 cases of high-risk lesions. Conclusion : In women with recently diagnosed breast cancer, 3.0-T MR imaging showed additional suspicious findings in 33.7%. The sensitivity and specificity for detecting additional breast cancer was 100% and 89.3%, respectively.

The purpose of this study is to help self-healing by identifying self-description by utilizing the self-description diagnosis of literary therapy and the resonance of the work narrative. Therefore, the research was conducted through the methodology of literature therapy, which uses the self-introduction team of literary therapy and basic photography team to understand their own narrative and to heal themselves through resonance with the work narrative. Through this study, we understood that it is possible to understand and identify and understand one's psychological problems through self-description and self-culture techniques. This case study revealed that it can be used as a new technique for understanding self-description by applying the methodology of literary therapy and for healing self-exploration through resonance with the work narrative.

When we design the control system used Programmable Logic Controller(PLC), we program the main algorithm by Ladder Diagram(LD) in many standard language. But if we use an Sequential Function Chart(SFC), we is easy to know the sequential flow of control, to maintenance the controller and to describe a program. Even though a SFC have many merits, A SFC have some problems like a condition and a function of self test. Therefore this thesis show an efficient function of self test and we confirmed its feasibility through actual example.

목적： 수소 자기 공명 분광기법은 자기공명 영상으로는 얻을 수 없는 화학적 성분에 대한 정보를 제공하여 암을 포함한 여러 질환의 진단과 예측에 사용된다. 이 기법으로는 어떤 특정한 작은 체적을 선택하여 그 부위에만 자기공명 분광신호를 획득하는 단일 체적기법과 체적 전체를 위상변화를 주면서 여기시킨 후, 데이터 후처리 과정에서 체적별로 분리해내는 다중체적기법이 있다. 다중체적기법은 더 긴 영상 획득시간에도 불구하고 단일 체적기법에 비하여 분광상을 대조군과 비교할 수 있는 잇점이 있다. 뇌를 진단하는데 사용하기 위한 수소분광선을 얻기 위하여 다중체적 화학적 영상기법을 개발하여 모형과 자원자에 대하여 적용하여 그 유용성 확인하였다.
