It was experimented if Brain Healing Therapy(BHT) and aromatherapy that was developed based on academic theory of cranis sacral therapy that is brain therapeutic exercise influence on brain wave targeting the female whose ages are between 30 and 40 having huge stress physically and psychosocially. Neuro harmony, PCDK07- 07012 was used as brain wave monitor and it was investigated if the statistic relation between test group and control group has the significant meaning regarding homogeneity evaluation for each index through t-test. As the results of carrying out paired-samples test against the change of brain quotients between test group and control group before and after implementing massage, it was recognized that brain healing therapy that applies aroma relaxes brain tension status more than brain healing therapy as it supports the increase of α-wave and also influences on psychological stability as it affects balance status of brain.

유방감마스캔을 이용한 유방암 검진

차은숙 대한영상의학회 2019 대한영상의학회지 Vol.80 No.1

The sensitivity and specificity of breast cancer screening with mammography in dense breasts are very low, and increasing attention has been paid to breast density and screening in highrisk groups. Therefore, a supplemental screening modality is needed. Mammography and supplementary ultrasound screening are mainly based on the differences between cancerous and normal breast parenchyma on an anatomical basis, whereas breast-specific gamma imaging is a functional imaging approach examining the physiological phenomena of blood flow and mitochondrial activity, which are increased in cancer cells. The purpose of this review is to discuss the diagnostic methods, clinical results, clinical application, and considerations of breast cancer screening with breast-specific gamma imaging using 99mTc-sestamibi. 치밀유방에서의 유방촬영술은 민감도와 특이도가 매우 낮으며 유방의 치밀도와 고위험군에서의 유방암 검진에 대한 관심이 높아지고 있다. 이에 유방촬영술의 보조적인 영상검사가 필요하다. 유방촬영술이나 초음파검사는 주로 유방암과 정상 유방 실질의 해부학에 근거한 영상검사인데 비해 방사성동위원소를 이용한 유방감마영상은 생리학적인 기반으로 암세포에서 증가된 혈류와 미토콘드리아 활성화에 의해 유방암을 진단한다. 본 종설에서는 99mTc-sestamibi를 이용한 유방감마영상의 유방암 검진에 관한 검사방법, 임상연구 결과, 임상 적용, 영상 판독 기준 및 유방암 검진에서의 문제점에 관하여 알아보고자 한다.

선호도 높은 가상인간의 공통적 캐릭터 디자인

차은숙,이재준 한국영상학회 2023 한국영상학회 논문집 Vol.21 No.3

Virtual characters that exist separately in the virtual space are developing into virtual humans by interacting with the public through social media, identical to real humans. Virtual humans approach the public by forming a bond of sympathy that can be felt with real human friends. In addition, virtual humans convey social messages with their own point of view, share their own beliefs and hobbies, and form human relationships with the public. Existing characters appearing in various media have been studied, focusing on elements that have already been created and exist in the virtual world, such as a story centered on a character and the symbols and colors of the external design, proportions, and props. Today's virtual human does not exist in a pre-determined worldview but is an active human who communicates with the public, changes its appearance, and provides timely messages when communicating with the public. Therefore, research on the preferences of virtual humans also focuses on the likeability and impression formation formed in real humans. Therefore, this paper analyzes the design of virtual humans based on the theory of impression formation, which explains the formation of interpersonal impressions inface-to-face communication situations. Representative virtual characters with high preference in social media were selected and analyzed. Socially classified gender, age, nationality, race, and occupation were investigated, and the relative characteristics of virtual human appearances, messages, and keywords were organized. A Latino virtual human from Brazil had a high preference, and a virtual human who communicated with the public with clear subjectivity based on his or her beliefs had a high preference.Virtual humans expressing their thoughts form a positive impression through active communication as the relationship with the public deepens and becomes intimate. 가상공간에 분리되어 존재하던 가상의 캐릭터는 마치 실존하는 인간과 같이 소셜 미디어를 통해 대중들과 상호작용하면서 가상인간으로 발전하고 있다. 가상인간은 실제 인간 친구에게서 느낄 수 있을 것 같은 공감대를 형성하며 대중에게 다가온다. 또한 가상인간 스스로의 관점을 가지고 사회적 메시지를 전달하기도 하며, 스스로의 신념과 취미를 공유하며 대중과 인간관계를 형성하기도 한다. 각종 미디어에 등장하는 기존 캐릭터는 해당 캐릭터를 중심으로 한 스토리, 외형적 디자인이 갖는 상징 및 색채, 비율 및 소품 등의 가상 세계에 이미 만들어져 존재하는 요소들을 중심으로 연구되었다. 오늘날의 가상인간은 이미 만들어진 결정된 세계관 속에 존재하지 않으며 대중과 소통하며 외형을 바꾸고 적시성 있는 메시지를 가지고 대중과 소통하는 능동적 인간이다. 따라서 가상인간의 선호도 연구는 실존하는 인간에게서 형성되는 호감도와 인상형성과 닮아있다. 따라서 본 논문은 대면 커뮤니케이션 상황에서 대인인상 형성을 설명하는 인상형성 이론에 기초하여 가상인간의 디자인을 분석하였다. 소셜 미디어에서 선호도 높은 대표 가상 캐릭터를 선정하여 분석하였다. 사회적으로 범주화 되는 성별, 나이, 국적, 인종, 직업을 조사하였고, 상대적 특징인 가상인간의 외모, 메시지, 키워드를 정리하였다. 브라질 출신의 라틴계 가상인간이 높은 선호도를 보이고 있었고, 자신의 신념을 바탕으로 분명한 주관을 가지고 대중과 소통하는 가상인간이 높은 선호도를 보이고 있었다. 자기 생각을 표현하는 가상인간은 대중과의 이해관계가 깊어지고 관계가 친밀해지면서 적극적인 의사소통으로 긍정적인 인상을 형성한다.

Objectives: This pilot study aimed to obtain preliminary data on the associations between atherosclerosis and periodontitis, physical health status, and general and oral health behaviors. Methods: Thirty-three subjects were recruited from among those who underwent carotid computed tomography (CT) angiography and general health check-up at the Seoul National University Hospital Health Examination Center (SNUHHEC). Two trained dentists conducted a periodontal examination to evaluate probing pocket depth and clinical attachment loss. A self-administered questionnaire was completed by study subjects, following informed consent. Data on physical health status were collected through review of medical records from the SNUHHEC. Information on general health behavior was obtained from the self-reported questionnaire. Descriptive and comparative analyses were performed using IBM SPSS Statistics 21.0®. Statistical significance was set at P<0.05. Results: A marginal, but non-significant association was noted between atherosclerosis and periodontitis (P=0.373). Flossing habit showed a significant association with periodontitis (P=0.007) and obesity (P=0.033). A possible association was noted between daily exercise and flossing (P=0.073). The habitual use of interdental brush also showed borderline association with smoking (P=0.098) and a stronger association with previous periodontal treatment (P=0.067); however, these associations were not statistically significant. Conclusions: Our pilot study did not show an association between arteriosclerosis and periodontal disease. However, positive oral health care behavior, especially flossing, seems to alleviate arteriosclerosis. In other words, in this pilot survey, we confirmed the possibility that healthy oral care behavior can help to alleviate arteriosclerosis. Future large-scale studies are needed to confirm whether positive oral health care behaviors improve overall health.

Purpose: The purpose of this study is to describe characteristic contrast enhanced MR mammographic findings of ductal carcinoma in situ (DCIS) and also DCIS with microinvasion. Materials and Methods: From January 2000 to July 2005, 32 women with 33 lesions affected by DCIS or DCIS with microinvasion underwent contrast enhanced MRI, and they were then retrospectively evaluated. All the patients had previously undergone mammography and ultrasonography. All the findings of mammography, ultrasonography (US), and MRI were analyzed by using an ACR BI-RADS lexicon. Results: All 33 cases were enhanced on the enhanced MR images. A smooth margined homogeneous enhanced mass was seen in the two (2/33) cases, and nonmass enhancement was seen in 31 (31/33) cases. Among the non-mass enhancement, focal enhancement (7/31), ductal enhancement (5/31), segmental enhancement (9/31), and regional enhancement (10/31) were observed. On the kinetic study, a wash-out pattern (10/33), a plateau pattern (20/33), and a persistent pattern (3/33) were demonstrated. No significant differences were noted between the pure and microinvasive DCIS. Conclusion: There is no significant difference between pure and microinvasive DCIS. However, contrast enhanced MR images can demonstrate occult foci, multifocal lesion and the tumor extent of DCIS on mammogram or ultrasonogram. 목적: 관상피내암과 미세침윤을 동반한 관상피내암의 조영 후 자기공명영상 소견의 특징을 알아보고자 하였다. 대상과 방법: 2000년 1월부터 2005년 7월까지 관상피내암이나 미세침윤을 동반한 관상피내암으로 진단되고 자기공명영상을 시행한 32명의 환자의 33 증례를 대상으로 후향적으로 분석하였다. 이들 환자에서 자기공명영상과 검사 전에 시행한 유방촬영영상과 초음파 영상은 ACR BI-RADS에 따라 분류하였다. 결과: 자기공명영상검사에서 역동적 조영검사시에는 33예인 모든 병변이 조영증강 되었다. 전체 33예 중 명확한 경계의 균일하게 조영 되는 종괴가 2예였고, 비종괴성 조영 병변이 31예였다. 비종괴성 조영 병변 31예 중 국소 조영 증강 병소가 7예, 관상 병소가 5예, 구역성 병소가 9예, 지역성 병소가 10예였다. Time-signal intensity curve 에서, 조기 조영 후 소실되는 경우가 10예, 평탄형을 보이는 경우가 20예, 지속적인 조영을 보이는 경우가 3예였다. 관상피내암과 미세침윤을 동반한 관상피내암의 자기공명영상 소견의 차이는 뚜렷하지 않았다. 결론: 관상피내암과 미세침윤을 동반한 관상피내암의 자기공명영상 소견의 뚜렷한 차이는 없었다. 그러나 조영 후 자기공명 영상은 유방촬영영상이나 초음파 검사에서 보이지 않는 관상피내암을 진단하거나, 다발성 병변을 찾거나, 관상피내암의 범위를 확인하는데 이용될 수 있다.

Purpose To identify differences in ultrasonography (US) feature, clinical and pathological characteristics including immunohistochemical characteristics between small breast cancer (pathologic size ≤ 5 mm) and large breast cancer (> 5 mm). Materials and Methods A total of 528 invasive breast cancer lesions in 475 patients were included. US features with clinical and pathological characteristics were evaluated according to pathologic size. US Breast Imaging-Reporting and Data System findings and final assessments were recorded for each lesion. Standard references were based on surgical pathologies. Results Of 528 invasive breast cancer lesions, 62 were small breast cancers. Small breast cancers showed a higher rate of oval, round shape, parallel orientation; circumscribed margin; and iso/solid and cystic echo pattern, with no posterior feature. The final assessment of category 4 was also a dominant factor in small breast cancer. Early stage, asymptomatic state, and extensive ductal carcinoma in situ component were associated with small breast cancers. Conclusion Our results show that small breast cancers have less suspicious US features than large breast cancers.
