Hyperechoic lesions of the breast encompass a wide range of conditions that are occasionally encountered during breast ultrasonography. Although typical hyperechoic lesions with a distinct fat component on imaging are well known, some hyperechoic lesions are diagnosed as unexpected pathology, making the radiology-pathology correlation difficult. Therefore, understanding the pathology of these lesions and how it correlates with imaging findings can help radiologists accurately diagnose and properly manage a range of related conditions. This article presents a pictorial review of unexpected hyperechoic benign and malignant breast lesions, with a focus on the pathological conditions that give rise to the hyperechoic pattern.

Objectives : The purpose of this study is to find out the effects of Chuna treatment on neck pain caused by traffic accidents. Methods : The 10 patients were divided into 2 groups, with Group A treated with Acupuncture and Chuna, while group B was treated with Acupuncture only. We measured the Visual Analog Scale(VAS), Pain Disability Index(PDI) and Pressure Pain Thresholds before and after treatment in each group. The statistical analysis was performed by using a Mann-Whitney U test and Wilcoxon signed rank test. Results : 1. Group A showed significant improvements in VAS, PDI and Pressure Pain Thresholds(p<0.05). 2. Group B was significantly improved in VAS(p<0.05). However, there was no statistical significance in PDI and Pressure Pain Thresholds(p>0.05). 3. There was no statistical significance between Group A and Group B before and after treatment. Conclusions : These results imply that Chuna treatment with Acupuncture would beeffective and useful on the neck pain caused by traffic accidents.

The main purpose of this study was to explore the variables predicting mothers' parenting attitudes in Korean-Japanese multi-cultural families in comparison to Korean families. Differences in parental beliefs, life-satisfaction and parenting attitudes between these two groups were also examined. Data were collected via questionnaires from 110 Japanese and 168 Korean mothers of young children. Results revealed that mothers' beliefs on value of child and parental role, life-satisfaction and parenting attitudes were different across the families. Costed-concept of child and low life-satisfaction predicted 'shaming' and 'coercive' parenting for Japanese mothers whereas parental role beliefs as an 'authority' figure predicted 'shaming' parenting for Korean mothers. Life-satisfaction was most influential to predict 'affectionate-rational' parenting for both group.

Objectives : This report intended to estimate effects of Jung-an acupuncture on the acquired torticollis caused by muscle contraction. Methods : The patients were treated by Jung-an acupuncture, herb medication and Physical treatment daily. The improvement of the patients was judged by Toronto Western Spasmodic Torticollis Rating Scale(TWSTRS), Tsui's score and Visual Analogue Scale(VAS). Results : After 7 days of treatment, the 2 patients' neck pain and cervical movement were improved. Also, TWSTRS score, Tsui's score and VAS were all reduced. Conclusions : As the Jung-an acupuncture's theological base is organized with meridian theory and myofacial release therapy, We considered the Jung-an acupuncture is effective not only for the skin disease but also for the muscle problem such as torticollis.

Review of Statistical Methods for Evaluating the Performance of Survival or Other Time-to-Event Prediction Models (from Conventional to Deep Learning Approaches)

박서영,Park Ji Eun,Kim Hyungjin,Park Seong Ho 대한영상의학회 2021 Korean Journal of Radiology Vol.22 No.10

The recent introduction of various high-dimensional modeling methods, such as radiomics and deep learning, has created a much greater diversity in modeling approaches for survival prediction (or, more generally, time-to-event prediction). The newness of the recent modeling approaches and unfamiliarity with the model outputs may confuse some researchers and practitioners about the evaluation of the performance of such models. Methodological literacy to critically appraise the performance evaluation of the models and, ideally, the ability to conduct such an evaluation would be needed for those who want to develop models or apply them in practice. This article intends to provide intuitive, conceptual, and practical explanations of the statistical methods for evaluating the performance of survival prediction models with minimal usage of mathematical descriptions. It covers from conventional to deep learning methods, and emphasis has been placed on recent modeling approaches. This review article includes straightforward explanations of C indices (Harrell’s C index, etc.), timedependent receiver operating characteristic curve analysis, calibration plot, other methods for evaluating the calibration performance, and Brier score.

춤에서 우연의 개념과 확장 가능성 탐색: 작품의 창작 및 수용 과정을 중심으로

This study aims to explore the humanistic domain of “chance”, which is considered difficult to approach even with technology such as machines or robots. Accordingly, the purpose is to examine the various concepts of chance that have been created through works of art and to focus on the specific aspects of how chance has been utilized in the process of creating and accepting dance. To look into the different aspects of chance that are involved in the choreographic process, this study selected and analyzed works by Cunningham, Bausch, and McGregor. The first form in which chance is utilized in dance is a method of extracting memories and experiences from the unconscious of the dancer with minimum intervention of conscious in their movements. The second form involves the choreographer relinquishing the control of dance composition not only from their own conscious decisions but also from their unconscious, transcending the individual choreographer and turning the decision-making process 'outward'. The third form of chance involves presenting a range of possibilities to the choreographer through the probability of artificial intelligence and the ambiguity of algorithms, which can result in a different outcome each time, expanding the choreographer's range of choices. This study aimed to explore “external realm” beyond the choreographer's thoroughly planned intentions. Therefore, this study focused on the choreographic methods that create dance ‘outside’ of the consciousness of the artist or even ‘beyond’ the artist by activating the periphery that excludes the range consciously intended by the artist. As a result, it was possible to confirm that chance deeply intervenes in the creating and accepting processes of art in various forms, affecting them in new and creative ways, much like our lives do not always flow as intended.

박서영(Park Seoyoung),박은경(Park Enekyung) 한국문화융합학회 2020 문화와 융합 Vol.42 No.12

본 연구는 관광활동이 우울에 미치는 영향 관계에서 컴퓨터, 인터넷 사용 등 디지털정보화 수준이 조절효과를 보이는지에 대해 65세 이상 집단과 65세 미만 집단으로 구분하여 검증하였다. 이를 위해 국민노후보장패널 7차년도 자료에서 연령에 대해 응답한 11,708명에 대해 조사하였고 연구모형 검증을 위해 SPSS 25.0 package를 이용하였다. 종속변수인 우울은 CES-D를 사용하여 우울을 측정하였고 점수가 클수록 우울이 심한 것으로 판정하였고 독립변수인 관광활동은 여행, 소풍 등 관광활동을 여가로 주로 선택하는 경우들을 합하여 연속변수화하였으며 조절변수인 디지털정보화 수준은 컴퓨터, 인터넷의 활용으로 측정하였다. 그리고 우울에 영향을 미치는 인구사회학적 요인으로 성별, 연령, 학력, 배우자유무, 건강상태, 소득을 통제변수로 설정하였다. 연구의 결과는 다음과 같다. 첫째, 관광활동은 우울에 정적 영향을 미치는 것으로 나타났고 이러한 결과는 65세 이상 집단과 65세 미만 집단 모두에서 유의하였다. 둘째, 디지털정보화수준은 우울에 부적 영향을 미치는 것으로 나타났고 이러한 결과는 65세 미만 집단에서만 유의하였다. 셋째, 디지털정보화 수준은 관광활동과 우울 관계에서 조절효과를 나타내는 것으로 나타났고 이러한 결과는 65세 미만 집단에서만 유의하였다. 넷째, 관광활동과 우울 간 디지털정보화 수준의 조절효과에서 성별, 연령, 학력, 배우자유무, 건강상태, 소득이 영향요인으로 검증되었다. 결론적으로 디지털정보화 수준이 높을수록 관광과 우울의 관계에서 우울의 수준을 감소시키고 이러한 결과는 65세 미만 집단에서 유의하였고 이러한 결과들을 바탕으로 뉴노멀 시대의 다양한 제언들을 제시하였다. This study investigated whether the level of digital information service, such as computer and Internet use, is effective in relation to the impact of tourism activities on depression. Subjects were divided into groups aged 65 or older, and those under 65. In the study, 11,708 people who responded by age were surveyed from the 7th year data of the Korean Retirement and Income Study. The results of the study were as follows: First, tourism activity was shown to have a static effect on depression, for both groups, those aged 65 and older and those under 65. Second, digital information service levels were found to have an adverse effect on depression, and these results were only noted for those under 65 years of age. Third, the level of digital information service was shown to represent an adjustment effect in the relationship between tourism activities and depression, and this was only noted for those under 65 years of age.

독립변수의 로그 변환에서 영(0) 값의 처리 방법

박서영(Seo Young Park) 한국자료분석학회 2023 Journal of the Korean Data Analysis Society Vol.25 No.1

의학, 보건학 연구에서 선형회귀분석을 수행할 때 독립변수가 왼쪽으로 심하게 기울어진 분포를 가진 경우 로그 변환을 취하는 것이 일반적이다. 그 중 실험실 수치와 같은 변수는 분포가 기울어져 있으면서도 검출한계 미만의 값이 0으로 기록되어 바로 로그 변환을 취할 수 없는 경우가 많다. 이러한 경우 로그 변환을 취하기 전에 0 값을 대체하는 전처리 방법으로 여러 가지 기법이 문헌을 통해 제안되었으나, 이러한 방법 대부분이 번거로운 계산 과정을 요구하기 때문에 실제로는 거의 쓰이지 않는다. 이 연구에서는 문헌에는 등장하지 않으나 실제 임상 연구 현장에서 흔히 쓰이는 다섯가지 방법(1만큼 이동, 영 제외 최솟값의 절반만큼 이동, 영 제외 최솟값의 제곱근만큼 이동, 영 제외 최솟값의 절반으로 영 대체, 영 제외 최솟값의 제곱근으로 영 대체)을 정리하여 소개한다. 각 방법의 성능을 비교하기 위해 로그노말 분포를 가진 독립변수와 선형 관계를 가진 반응변수의 값을 생성한 데이터를 가지고 모의실험을 수행한 결과, 실제로는 가장 흔하게 쓰이는 방법인 1만큼 이동 방법이 가장 좋지 않은 성능을 보였으며, 영 제외 최솟값의 절반만큼 이동 방법과 영 제외 최소값의 절반으로 영 대체 방법이 가장 안정적인 성능을 보였다. In studies in medical science or public health, it is common to apply log-transformation to independent variables that have severely right-skewed distribution. Among such variables, lab values have skewed distribution but have zeros due to limit of detection, which makes it impossible to apply log-transformation directly. There have been various methods proposed to deal with such situation, but most of these methods are rarely used in practice because they usually require additional step in calculation. In this study, five methods that removes zeros (shift by 1, shift by half of the smallest nonzero, shift by square root of the smallest nonzero, replace zeros with half of the smallest nonzero, replace zeros with square root of the smallest nonzero are presented. To compare performances of these methods we performed a simulation study based on randomly generated data with independent variable with log-normal distribution and response variable which has linear relationship with the independent variable, Shift by 1 method has the worst performance, and overall shift by half of the smallest nonzero method and replace zeros with half of the smallest nonzero method showed most stable performances.

논문 : 디지털 테크놀로지를 활용한 무용공연의 매체미학적 특성 연구

박서영 ( Seo Young Park ) 한국무용기록학회 2011 무용역사기록학 Vol.22 No.-

본 연구는 현재 다양하게 이루어지고 있는 디지털 테크놀로지와 조우한 무용의 특성을 찾기 위하여 매체미학적 관점을 활용하였다. ``매체는 메시지``라고 언명한 마셜 맥루언의 주장은 자칫 지나치게 극단적인 형식주의로 나아가는 것 같지만, 예술의 형식에 담겨진 내용은 그것을 표현하고자 하는 매체의 특성에 크게 의존한다는 사실을 고려한다면 수용의 근거가 마련된다. 또한 문자문화 시대에서 디지털 시대로 접어들면서 시각 중심의 감각에서 총체적 감각으로서의 촉각을 살려냈으며, 춤과 완전히 접목된 매체는 이미 인간 몸의 일부로 춤추는 무용수의 몸은 매체를 통하여 확장됨을 살펴본다. 이렇게 매체와 합체된 무용은 실존하지 않는 시·공간까지 실제 공연의 시·공간으로 편입시키게 되며, 이때 춤추는 무용수와 테크놀로지 그리고 이를 관람하는 관객의 소통 감각은 기존 공연의 안무가-무용수-관객의 삼각구도로 해석되지 않는 변화가 발생한다. 이렇듯 매체미학적 시각을 활용함으로써 기존의 전통적인 무용 작품과 비교해 테크놀로지와 결합된 무용공연의 특성은 다양하게 나타났는데, 크게 ``확장``과 ``총체성``의 개념을 이끌어낼 수 있었다. This study adopted the perspective of media aesthetics to determine the characteristics of dance that has encountered with digital technology, which is diverse and popular. Marshall Mcluhan`s claim, "The medium is the message," may appear to pursue extreme formalism, but it can be accepted, considering that the content in the form of art largely depend on the characteristics of the medium that expresses it. In addition, as the age of letters has changed into the digital era, senses centering on visual sense has evolved into whole sense including tactile sense, and the medium converged with dance has shown that dancer`s body in dance has extended through the medium. Likewise, dance converged with medium can incorporate non-existent time and space into the real time and space during performances, bringing about the changes that the dancer, technology and audiences` communication are not interpreted as constituting the traditional triangles of choreographer-dancer-audience. In this sense, it can be said that by adopting the perspective of media aesthetics, the characteristics of technology converged with dance vary compared with existing dance works and that the concepts of ``extension`` and ``totality`` can be drawn from the effects.
