This paper analyzed factors for employees to violate information security policy in financial companies based on the theory of reasoned action (TRA), general deterrence theory (GDT), and information security awareness and moderating effects of perceived sensitivity of customer information. Using the 376 samples that were collected through both online and offline surveys, statistical tests were performed. We found that the perceived severity of sanction and information security policy support to information policy violation attitude and subjective norm but the perceived certainty of sanction and general information security awareness support to only subjective norm. Also, the moderating effects of perceived sensitivity of customer information against information policy violation attitude and subjective norm were supported. Academic implications of this study are expected to be the basis for future research on information security policy violations of financial companies; Employees' perceived sanctions and information security policy awareness have an impact on the subjective norm significantly. Practical implications are that it can provide a guide to establish information security management strategies for information security compliance; when implementing information security awareness training for employees to deter violations by emphasizing the sensitivity of customer information, a company should make their employees recognize that the customer information is very sensitive data.

업샘플링 깊이맵은 깊이 카메라로부터 획득된 깊이맵의 공간 해상도를 증가시키는 방법이다. 깊이맵의 성능은 입체영상, 멀티뷰의 3D 입체감과 밀접한 관계가 있다. PSNR 등의 객관적 메트릭으로 깊이맵의 업샘플링 성능을 평가하고, 생성된 입체영상은 주관적 평가를 통해서 입체감 및 시각적 피로도를 조사한다. 후자의 주관적 평가는 인적 물적 자원을 필요로 하는 반면에, 전자의 객관적 메트릭은 수학적 표현으로 정량적 수치값을 알려준다. 따라서 주관적 평가와 높은 상관관계를 가지는 객관적 메트릭이 주관적 평가를 대체할 수 있다면 많이 시간을 필요로 하는 주관적 평가가 불필요하다. 이를 위해 본 논문에서는 다양한 객관적 메트릭과 3D 주관적 평가 사이의 관계를 조사한 후에, 이용한 메트릭에 기반한 주관평가와 상관관계가 높은 객관적 메트릭을 제안한다. 업샘플링된 깊이맵의 성능을 측정하기 위해 다양한 참조영상 및 무참조영상 평가 메트릭들을 이용하였다. 주관적 평가는 DSCQS 입체영상 테스트로 수행되었다. 세 종류의 상관관계의 활용 및 분석을 통해서, SSIM과 Edge-PSNR이 주관적 평가를 대체할 수 있는 적합한 객관적 메트릭임을 실험을 통해서 검증하였다.

본 연구에서는 음향적으로 결합된 공간에서 개구부의 크기변화에 따른 주관적 잔향감의 평가를 청취실험을 통해 실시하고 주관적 잔향감을 예측할 수 있는 새로운 물리적 지표를 제시하고자 하였다. 대상공간의 물리적 음향특성은 물론 주관적 음향평가를 위하여 1/10 스케일의 모형을 제작하여 실험에 사용하였다. 주관적 잔향감평가를 위해 바이노럴 임펄스 리스펀스(binaural impulse response)를 더미헤드(dummy head)를 이용해 녹음하여 가청화작업(auralization)을 거쳐 청취실험에 음원으로 제시하였다. 청취실험결과, 주실이 흡음력이 낮은 잔향부실과 음향적으로 결합할 경우 개구율이 12.5%(주실면적대비 1.97%)일 때 주관적 잔향감이 가장 큰 것으로 나타났으며 개구율이 25%(주실면적대비 3.94%)이상일 때 주관적 잔향감이 감소하는 것으로 나타났다 주실이 흡음력이 높은 흡음부실과 음향적으로 결합할 경우 개구율이 $0%{\sim}6.25%$까지(주실면적대비 $0%{\sim}0.99%$)는 주관적 잔향감이 변화하지 않다가 개구율이 12.5%에서부터 점차적으로 감소하는 것으로 나타났다. 이중감쇠현상을 나타내는 물리적 지표 T30/T15는 개구율의 변화에 따른 주관적 잔향감과 상관도가 거의 없는 것으로 나타났으며 저자들이 제시한 새로운 지표 T30/Tbp이 주관적 잔향감과 높은 상관도를 보였다. 또한 개구율 변화에 따른 이중감쇠현상은 초기나 중기감쇠부분에서보다 후기감쇠부분에서 에너지가 현저하게 증가하는 것으로 나타나 T30/T15에 비해 LDT/EDT나 T3/T1가 주관적 잔향감과의 상관성이 높은 것으로 나타났다.

Background: To assess the accuracy of ultrasound in differentiating endometrioma from ovarian cancer and to describe pattern recognition for atypical endometriomas mimicking ovarian cancers. Materials and Methods: Patients scheduled for elective surgery for adnexal masses were sonographically evaluated for endometrioma within 24 hours of surgery. All examinations were performed by the same experienced sonographer, who had no any information of the patients, to differentiate between endometriomas and non-endometriomas using a simple rule (classic ground-glass appearance) and subjective impression (pattern recognition). The final diagnosis as a gold standard relied on either pathological or post-operative findings. Results: Of 638 patients available for analysis, 146 were proven to be endometriomas. Of them, the simple rule and subjective impression could sonographically detect endometriomas with sensitivities of 64.4% (94/146) and 89.7% (131/146), respectively. Of 52 endometriomas with false negative tests by the simple rule, 13 were predicted as benign masses and 39 were mistaken for malignancy. Solid masses and papillary projections were the most common forms mimicking ovarian cancer, consisting of 38.5% of the missed diagnoses. However, with pattern recognition (subjective impression), 32 from 39 cases mimicking ovarian cancer were correctly predicted for endometriomas. All endometriomas subjectively predicted for ovarian malignancy were associated with high vascularization in the solid masses. Conclusions: Pattern recognition of endometriomas by subjective assessment had a higher sensitivity than the simple rule in characterization of endometriomas. Most endometriomas mimicking ovarian malignancy could be correctly predicted by subjective impression based on familiarity of pattern recognition.

This study investigates the effect of site characteristics in fashion social commerce and SNS subjective norms on the attitude of consumers towards social commerce and their purchase intentions for fashion products. In addition, this study tests consumer responses through a comparison of a group purchase mall versus a private mall. Respondents are limited to consumers aged 20 to 39 who have recently purchased fashion products through social commerce over the last month. Four hundred samples were used for the final analysis. Descriptive statistics, Cronbach's alphas, a confirmatory factor analysis, and a structural equation modeling analysis were conducted. The results are as follows. Product value, convenience and SNS subjective norms without trust significantly influenced the consumer attitude towards social commerce, and the attitude of consumers positively influenced the purchase intentions of fashion products. In the group purchase mall, only convenience affected the attitude of consumers; in the private mall, product value, convenience and SNS subjective norm had an effect on the attitude of consumers. In addition, the SNS subjective norm positively influenced purchase intentions directly as well as indirectly. Social commerce ought to offer product value and create a simple and convenient design to raise the purchase intentions of fashion products; in addition, they should use SNS functions to inform consumers of social commerce. It is imperative to implement different marketing strategies according to social commerce type.

To improve wellness and quality of life by recognizing the health efforts of stress, the author estimated the relationships between stress, subjective symptoms and clinical diagnosis through a questionnaire and a battery of specified laboratory tests; electrocardiography, blood pressure, cholesterol, aspartate aminotransferase(AST), alanine aminotransferase(ALT), gamma glutamyl transferase$(\gamma-GTP)$, fasting blood sugar, gastro-endoscopy or UGI, abdominal sonography, etc. The data was gathered from 337 clients who were undergoing multiphasic screening program at a University Hospital from January to March 1998. The mean age of subjects was $46.5{\pm}11.2$ years and the mean of body mass index was $24.0{\pm}3.7kg/m^2$. The mean vol of stress was $18.5{\pm}6.0$ expressed as the score out of 40. By general characteristics and lift style among male, mean level of stress was significantly higher in case of lower socioeconomic status, habitual drug use, longer daily working time(>10 hours), no regular exercise, drinkers, irregular meal, skip-ping breakfast(p<0.05). In case of female, that was significantly higher in case of lower education, lowe. socioeconomic status, longer daily working time(>10 hours), no regular exercise, drinkers, smokers, irregular meal, skipping breakfast(p<0.05). Significant correlations were observed between stress and subjective symptoms in all kinds of organ system (p<0.01). Correlation coefficients of stress among male were relatively high with neuro-psychiatric symptom$(\gamma=0.476)$ and cardio-vascular symptom$(\gamma=0.361)$ in order, and correlation coefficients of stress among female was highest with neuro-psychiatric symptom$(\gamma=0.371)$. The prevalence of the diagnosis through the battery of laboratory tests was high in upper gastrointestinal disorders and hypercholesterolemia in order in both sex group. Among male the mean score of stress was significantly high in ulcerative peptic disorder of upper gastrointestine and hepatopathy in order (p<0.05) . Among female that was significantly high in diabetes mellitus. In summary, it is likely that there are associations between stress, subjective symptoms and clinical diagnosis. To promote wellness and quality of life it would be of value that periodic stress evaluation program and stress management including apropriate control of smoking and drinking, regular exercise and meal.
