The purpose of this study was to investigate relationships among the drivers' driving behavior determinants (speeding, errors, wild driving, drunken driving and becoming distracted), mobility and subjective well-being (positive and negative affectivity, life satisfaction). Scores for driving behavior determinants (measured by DBDQ, Oh, 2011), mobility (measured by Jang et al., 2009) and subjective well-being (affectivity measured by SPANE, Diener et al., 2009, life satisfaction measured by Diener et al., 1985) were obtained using questionnaires. Self-reported scores of the variables of 62 older driver (Range=65~80year, Mean=68.4year) and 52 younger driver (Range=20~28year, Mean=23.9year) were analyzed using correlation analysis and path analysis. The results can be summarized as followings. First, the younger driver's speeding behavior was found to be positively related to mobility, but errors behavior was negatively to mobility. In particular, higher scores of speeding behavior induced higher level of mobility and higher scores of errors behavior induced lower level of mobility, which, in turn, increased life satisfaction and positive affectivity but not negative affectivity. Second, the older driver's errors and wild driving behavior was negatively related to mobility. In particular, higher scores of errors behavior induced lower level of mobility, which, in turn, increased positive affectivity and life satisfaction but decrease negative affectivity. The results suggested that older driver rather than younger driver’s mobility is more broadly affect their subjective well-being.

주미정 ( Mijung Joo ),이재식 ( Jaesik Lee ) 한국감성과학회 2016 감성과학 Vol.19 No.2

본 연구는 고령 운전자의 운전능력에 대한 주관적 평가와 객관적 수행, 이동성 및 주관적 안녕감 사이의 관련성을 살펴보기 위해 수행되었다. 고령 운전자들의 이동성과 주관적 안녕감은 설문조사 방법을 통해 측정하였다. 운전능력에 대한 주관적 평가는 다양한 운전 상황을 도시적으로 제시한 후 각 상황에서의 운전능력을 주관적으로 평정하게 하였고, 객관적 수행은 운전 시뮬레이션을 이용하여 측정하였다. 본 연구의 주요 결과를 요약하면 다음과 같다. 첫째, 고령 운전자의 운전능력에 대한 객관적 수행과 이동성 사이의 상관은 유의 하지 않았던 반면, 주관적 평가와 이동성 사이의 상관은 정적으로 유의하였다. 그리고 이동성과 주관적 안녕감의 하위요인 중 삶의 만족, 긍정 정서와는 정적인 반면, 부정 정서와는 부적인 상관이 관찰되었다. 둘째, 고령 운전자의 운전능력에 주관적 평가가 높을수록 이동성 수준이 높았고, 이러한 높은 이동성은 다시 주관적 안녕감의 하위 요인 중 삶의 만족과 긍정 정서를 정적으로 반면, 부정 정서는 부적으로 예측하였다. 본 연구의 결과들은 고령 운전자의 주관적 안녕감에는 객관적 운전수행보다는 운전능력에 대한 스스로의 평가가 더 중요한 기여를 할 수 있다는 것을 시사한다. The purpose of this study was to investigate relationships among the older drivers`` subjective evaluation and objective performances for driving ability, mobility and subjective well-being. Scores for mobility and subjective well-being were obtained using questionnaires. Diagram-based driving scenarios and driving simulation were used to measure subjective and objective driving abilities, respectively. The results can be summarized as followings. First, subjective evaluation scores of driving ability but not objective driving performance significantly correlated with mobility. Second, the higher level of mobility predicted higher life satisfaction, higher positive affectivity, and lower negative affectivity. Third, the older driver``s higher scores of subjective driving ability induced higher level of mobility, which, in turn, increased life satisfaction and positive affectivity but lower negative affectivity. The results suggested that subjective rather than objective ability for driving is more important in determining the level of old driver``s subjective well-being.

주미정(Mijung Joo),이재식(Jaesik Lee) 한국인지과학회 2012 인지과학 Vol.23 No.2

본 연구의 목적은 문화성향과 인지양식의 조합 조건에 따라 전역/국소처리에서 어떠한 차이가 관찰되는지 검토하는 것이다. 이를 위해 Singelis 등[1]의 문화성향 질문지(INDCOL)와 Choi 등[2]의 인지양식 질문지(AHS)에 기초하여 실험참가자들의 네 유형의 문화성향(개인주의, 집단주의, 수평성향 및 수직 성향) 점수와 인지양식 유형(분석적 또는 종합적 사고)에 따라 집단을 분류하고, 복합자극 유형(화살표로 구성된 복합도형 또는 알파벳 낱자로 구성된 복합문자)에 대한 전역/국소처리에서의 반응시간과 오반응율에서의 차이를 집단에 따라 비교하였다. 본 연구의 결과를 요약하면 다음과 같다. (1) 전반적으로 복합문자보다는 복합도형의 경우, 그리고 국소처리 조건보다는 전역처리 조건에서의 반응시간이 더 빨랐다. (2) 개인주의 성향과 수평 성향이 인지양식 유형과 각각 결합된 경우 전역/국소처리에서 집단간 반응시간 차이는 발견되지 않았으나, (3) 집단주의 성향과 수직 성향이 인지양식과 각각 결합된 집단의 경우에는 전역/국소처리에 대한 문화성향과 인지양식의 유의한 상호작용 효과가 모두 관찰되었다. 이러한 결과는 개인주의 성향 또는 수평성향보다는 집단주의 성향 또는 수직 성향이 종합적 사고 유형과 결합될 때 더 큰 전역선행성 효과를 가져 온다는 것을 시사한다. This study aimed to investigate the interactive effects of individual's cultural disposition (individualism, collectivism, horizontal disposition and vertical disposition) and cognitive style (analytic vs. holistic thinking) combination on differences in global precedence. For this purpose, the participants were divided into 4 different cultural disposition groups based on Singelis et al.'s(1995) INDCOL scale, and 2 cognitive style groups based on Choi et al.'s(2007) AHS, and required to respond selectively to global or local property of two types of compound stimuli (compound figure and compound letter). Reaction time and error rates for both global or local property were analyzed and compared as the dependent measurement. The results can be summarized as followings. First, faster responses were observed in compound figure condition than in compound letter condition, and to global property than to local property. Second, contrasting to individualism-cognitive style or horizontal dispositioncognitive style combinations, significant interaction effects both between collectivism and cognitive style, and between vertical disposition and cognitive style on global/local processing were found. This result indicated that combinations of collectivism- holistic thinking and vertical disposition- holistic thinking can induced larger global precedence effect than other combinations of cultural disposition and cognitive style.

본 연구는 운전자 연령대와 뇌손상 여부에 따라 다양한 반응시간 과제에서의 반응시간과 반응정확성에서 어떠한 차별성이 있는지 살펴볼 목적으로 수행되었다. 이를 위해 30-50대의 중년운전자, 65세 고령운전자, 그리고 65세 이상의 뇌졸중 고령운전자들을 대상으로 단순반응, 2-선택반응, 자극 이심률을 달리한 4-선택반응, 탐색반응 및 동적자극탐지 과제에 대한 수행을 비교하였다. 본 연구의 결과를 정리하면 다음과 같다. 첫째, 전반적으로 중년, 고령 및 뇌졸중 고령운전자 순으로 느린 반응시간을 보였으나 자극 이심률이 작은 조건(5^o)에 비해 큰 조건(10^o)에서 뇌졸중 고령운전자의 반응시간이 다른 집단에 비해 더 두드러지게 지연되었다. 둘째, 전체 반응시간에서 단순 반응시간을 감산한 반응시간을 분석한 결과, 2-선택반응 과제와 동적자극 탐지과제에서의 집단간 반응시간 차이는 유의하지 않았는데, 이것은 이러한 과제들에서의 반응시간 차이가 단순 반응시간에 의해 주로 결정된다는 것을 시사한다. 셋째, 일시적 기억을 요구하는 탐색과제에서는 두 고령운전자 집단이 중년운전자 집단에 비해 유의하게 느리고 부정확한 수행을 보였다. 넷째, 집단간 반응정확성에서의 차이는 선택 대안이 많은 과제와 기억을 요구하는 과제에서 두드러졌다. 이러한 결과는 기억 요구를 수반하는 탐색과제는 중년과 고령운전자 사이의 수행을, 반면 자극 이심률 조건은 뇌졸중 여부에 따른 고령운전자 집단에서의 수행 차이를 민감하게 반영할 수 있음을 시사한다. Differences in reaction time and accuracy were compared among driver groups of middle-, old-, and stroke old-age drivers using various reaction time tasks including simple reaction task, 2-choice task, 4-choice task with different stimuli eccentricity, search task, and moving target detection task. The results can be summarized as followings. First, although overall reaction time tended to be slowed with age and stroke, stroke old drivers showed significantly slower reaction time than the other driver groups when the stimuli were presented in a large eccentricity. Second, differences in reaction time for 2-choice task and moving target detection task seemed to be determined mainly by participants` simple reaction time. Third, the search task which required temporary retention of previously presented stimuli was found to be more sensitive in discriminating difference in reaction time between middle-age drivers and old-age drivers (including stroke old drivers). Fourth, reaction accuracy of old (and stroke old) drivers decreased when more stimuli alternatives were presented and temporary retention for stimuli was required. Altogether, memory demand in reaction time task can be sensitive to evaluate performance for different age groups, whereas size of useful field of view for brain stroke.

본 연구는 대학생을 대상으로 삶의 의미 추구와 영적 안녕 및 우울 간의 관계를 알아보고자 하였다. 이를 위해 의미 추구가 우울에 영향을 미치는 과정에서 영적 안녕의 하위 요인인 종교적 안녕과 실존적 안녕의 매개효과를 검증하였다. 대학생 225명을 대상으로 삶의 의미 척도, 우울 척도, 영적 안녕 척도를 사용한 설문조사를 실시하고, 구조 방정식 모형을 사용하여 요인 간 관계를 살펴보았다. 연구 결과를 살펴보면 대학생의 의미 추구는 종교적 안녕과 실존적 안녕에 유의한 정적 영향을 미치는 것으로 나타났다. 종교적 안녕은 우울을 증가시키는 효과를, 실존적 안녕은 우울을 감소시키는 효과를 가지는 것으로 나타났다. 의미 추구는 종교적 안녕과 실존적 안녕을 매개로 우울에 영향을 미쳤다. 종교적 안녕과 실존적 안녕의 매개 효과 크기를 비교한 결과 실존적 안녕의 매개 효과가 종교적 안녕보다 유의하게 큰 것으로 나타났다. 즉 대학생들이 의미추구를 할 때 종교적 안녕을 거쳐 우울을 높이는 반면, 실존적 안녕을 거쳐서는 우울을 낮추며 이 효과는 종교적 안녕보다 큰 것을 알 수 있다. 본 연구는 의미 추구가 긍정적 효과를 내는 매개 요인으로 영적 안녕을 살펴보았다는 의의가 있다. 또한 종교적 안녕과 영적 안녕이 우울에 각기 다른 방향으로 영향을 주는 것을 밝혔다. 따라서 대학생 우울을 감소시키기 위해서는 단순히 대학생의 의미 추구를 독려하는 것 뿐 아니라, 대학생의 실존적 안녕을 높일 수 있는 대안개발이 필요할 것이다. The purpose of this study is to investigate the relationships between search for meaning, spiritual well-being and depression in Korean college students. 220 college students were participated in survey included meaning in life questionnaire, center of epidemiologic studies depression scale, and spiritual well-being scale. And the structural equation modeling were examined to explore the mediating effect of spiritual well-being on process that search for meaning influence to depression. The results were followed. Correlational analysis showed that search for meaning was positively associated with religious well-being, existential well-being and depression. Also religious well-being and existential well-being were positively associated with depression. In structural equation modeling, search for meaning had effects to religious well-being and existential well-being positively. The religious well-being had positive effect on depression, otherwise existential well-being had negative effect on depression. Also search for meaning significantly influenced on depression mediated by religious well-being and existential well-being only. In addition, existential well-being had bigger indirect effect than religious well-being. The results of this study showed that search for meaning had a significant effect on depression though spiritual well-being. Indeed religious well-being and existential well-being had the counter effects on depression. Therefore this findings suggest that it is necessary to build the strategies in focus on existential well-being to reduce the depression among Korean college students.

조나리야,문우경,박정선,Joo Hee Cha,Mijung Jang,Min Hyun Seong 대한영상의학회 2008 Korean Journal of Radiology Vol.9 No.2

Objective: To compare the diagnostic performances of conventional ultrasound (US) and US elastography for the differentiation of nonpalpable breast masses, and to evaluate whether elastography is helpful at reducing the number of benign biopsies, using histological analysis as a reference standard. Materials and Methods: Conventional US and real-time elastographic images were obtained for 100 women who had been scheduled for a US-guided core biopsy of 100 nonpalpable breast masses (83 benign, 17 malignant). Two experienced radiologists unaware of the biopsy and clinical findings analyzed conventional US and elastographic images by consensus, and classified lesions based on degree of suspicion regarding the probability of malignancy. Results were evaluated by receiver operating characteristic curve analysis. In addition, the authors investigated whether a subset of lesions was categorized as suspicious by conventional US, but as benign by elastography. Results: Areas under the ROC curves (Az values) were 0.901 for conventional US and 0.916 for elastography (p = 0.808). For BI-RADS category 4a lesions, 44% (22 of 50) had an elasticity score of 1 and all were found to be benign. Conclusion: Elastography was found to have a diagnostic performance comparable to that of conventional US for the differentiation of nonpalpable breast masses. The authors conclude that BI-RADS category 4a lesions with an elasticity score of 1 probably do not require biopsy.

Yun, Bo La,Kim, Sun Mi,Jang, Mijung,Kang, Bong Joo,Cho, Nariya,Kim, Sung Hun,Koo, Hye Ryoung,Chae, Eun Young,Ko, Eun Sook,Han, Boo-Kyung Korean Society of Magnetic Resonance in Medicine 2017 Investigative Magnetic Resonance Imaging Vol.21 No.4

Purpose: To report on the current practices in breast magnetic resonance imaging (MRI) in Korea. Materials and Methods: We invited the 68 members of the Korean Society of Breast Imaging who were working in hospitals with available breast MRI to participate in a survey on how they performed and interpreted breast MRI. We asked one member from each hospital to respond to the survey. A total of 22 surveys from 22 hospitals were analyzed. Results: Out of 22 hospitals, 13 (59.1%) performed at least 300 breast MRI examinations per year, and 5 out of 22 (22.7%) performed > 1200 per year. Out of 31 machines, 14 (45.2%) machines were 1.5-T scanners and 17 (54.8%) were 3.0-T scanners. All hospitals did contrast-enhanced breast MRI. Full-time breast radiologists supervised the performance and interpreted breast MRI in 19 of 22 (86.4%) of hospitals. All hospitals used BI-RADS for MRI interpretation. For computer-aided detection (CAD), 13 (59.1%) hospitals sometimes or always use it and 9 (40.9%) hospitals did not use CAD. Two (9.1%) and twelve (54.5%) hospitals never and rarely interpreted breast MRI without correlating the mammography or ultrasound, respectively. The majority of respondents rarely (13/21, 61.9%) or never (5/21, 23.8%) interpreted breast MRI performed at an outside facility. Of the hospitals performing contrast-enhanced examinations, 15 of 22 (68.2%) did not perform MRI-guided interventional procedures. Conclusion: Breast MRI is extensively performed in Korea. The indication and practical patterns are diverse. The information from this survey would provide the basis for the development of Korean breast MRI practice guidelines.
