Objective: The aim of this study was to investigate the association between conceptual metaphors of affect and physical dimensions. Background: The evidence that affect is unconsciously linked to physical dimensions(e.g., position and color) has been obtained in western cultures. However, in eastern cultures, especially, in Korea, it has been seldom tested. It is indispensable to examine whether or not cultural differences exist for better understanding of the conceptual metaphors. Method: 50 positive and 50 negative words were adopted from previous studies in order to determine the relationship between physical domains and abstract affect. Three hypotheses were tested in this study: (1) Good is up. (2) Good is bright. (3) Good is right(for right-handers). The automatic association between valence(positive vs. negative) and vertical position (up vs. down) was investigated in experiment 1, in which 100 words were randomly presented on either the top or the bottom of a LCD screen and the evaluation time of the presented word was recorded. The unconscious association between valence and color(white and black) was examined in experiment 2, where each word was randomly presented in either white or black. Lastly, we tested whether right-handers tend to associate rightward space with positive ideas and leftward space with negative ideas. Results: Reaction time was faster when words were presented in metaphor congruent domains(e.g., 'positive words on the top, in bright color, and on right space vs. negative words on the bottom, in dark color, and on left region) than when they were shown in metaphor incongruent domains. Conclusion: The results might give the groundwork for various directions in further understanding perception, emotion, and behavior. Application: This study may provide useful points to GUI designers and service developers if further studies enhanced in validity and reliability are followed.

데이터베이스의 삭제된 데이터 복구와 관련된 그간의 연구는 삭제된 레코드가 트랜잭션 로그에 존재하는 경우이거나 데이터베이스 원본을 물리적 방식으로 수집하여 삭제 데이터의 탐지와 복구를 진행하는 방식이 주를 이루었다. 그러나 트랜잭션 로그가 존재하지 않거나 증거수집 현장에서 물리적 방식의 원본수집이 불가능한 경우 즉, 데이터베이스 서버 정지로 인해 피압수인이 업무상 손실 또는 권리침해를 이유로 거부하는 경우에는 적용하기 곤란한 한계가 있었다. 그러므로 증거수집 현장의 제약을 대비하기 위해 다양한 수집 방식을 살펴보고 이에 따른 삭제된 레코드의 복구 가능성에 대해서 확인해볼 필요가 있다. 이 논문에서는 Microsoft SQL Server 데이터베이스를 대상으로 하는 디지털포렌식 조사 시 원본 수집의 논리적 물리적 방식별로 수집된 원본 파일 내 삭제된 데이터의 잔존 여부를 실험하여 각 수집 방식에 따른 데이터 복구 가능성을 확인하였다.

멀티미디어 포렌식 분야에서 영상을 촬영한 카메라 모델 판별을 위한 연구가 지속되어 왔다. 점점 고도화되는 범죄 중에 불법 촬영 등의 범죄는 카메라가 소형화됨에 따라 피해자가 알아차리기 어렵기 때문에 높은 범죄 발생 건수를 차지하고 있다. 따라서 특정 영상이 어느 카메라로 촬영되었는지를 특정할 수 있는 기술이 사용된다면 범죄자가 자신의 범죄 행위를 부정할 때, 범죄 혐의를 입증할 증거로 사용될 수 있을 것이다. 본 논문에서는 영상을 촬영한 카메라 모델 판별을 위한 딥러닝 모델을 제안한다. 제안하는 모델은 4개의 컨볼루션 계층과 2개의 전연결 계층으로 구성되었으며, 데이터 전처리를 위한 필터로 High Pass Filter를 사용하였다. 제안한 모델의 성능 검증을 위하여 Dresden Image Database를 활용하였고, 데이터셋은 순차분할 방식을 적용하여 생성하였다. 제안하는 모델을 3 계층 모델과 GLCM 적용 모델 등 기존 연구들과 비교 분석을 수행하여 우수성을 보였고, 최신 연구 결과에서 제시하는 수준의 98% 정확도를 달성하였다.

Ginseng is the best known and most popular herbal medicine used worldwide. Ameliorating effects of ginseng were observed on the models of scopolamine-induced, aged or hippocampal lesioned learning and memory deficits. Further beneficial effects of ginseng were observed on neuronal cell death associated with ischemia or glutamate toxicity. In spite of these beneficial effects of ginseng on the CNS, little scientific evidence shows at the cellular level. In the present study, we have employed cultures of rat hippocampal neurons and examined the direct modulation of ginseng on NMDA receptor-induced changes in $[Ca^{2+}]_i$ and -gated currents using fura-2-based digital imaging and perforated whole-cell patch-clamp techniques, respectively. We found that ginseng total saponins inhibited NMDA-induced but less effectively glutamate-induced increase in $[Ca^{2+}]_i$ Ginseng total saponins also modulated $Ca^{2+}$ transients evoked by depolarization with 50 mM KCI along with its own effects on $[Ca^{2+}]_i$. Among ginsenosides tested, ginsenoside $Rg_3$ was found to be the most potent component for ginseng actions on NMDA receptors. Furthermore, we examined the inhibitory effects ofbiotransformants of ginsenosides on NMDA receptor using purified stereoisomers of ginsenosides. 20(S)-ginsenoside $Rg_3$ and its metabolite, 20(S)-ginsenoside $Rh_3$, produced the strongest inhibition while 20(S)-ginsenoside $Rh_1$ and Compound K produced the moderate inhibition on NMDA-induced increase in $[Ca^{2+}]_i$. The data obtained suggest that the inhibition of NMDA receptors by ginseng, in particular by 20(S)-ginsenoside $Rg_3$ and its metabolite, 20(S)-ginsenoside $Rh_2$, could be one of mechanisms for ginsengmediated neuroprotective actions.

This paper focuses on the dating and provenance of two paintings, Climbing the hill and View from St. John's Fort by the prominent Singaporean artist Liu Kang (1911-2004). Climbing the hill, from the National Gallery Singapore collection, was believed to have been created in 1937, based on the date painted by the artist. However, a non-invasive examination unveiled evidence of an underlying paint scheme and a mysterious date, 1948 or 1949. These findings prompted a comprehensive technical study of the artwork in conjunction with comparative analyses of View from St. John's Fort (1948), from the Liu family collection. The latter artwork is considered to be depicting the same subject matter. The investigation was carried out with UVF, NIR, IRFC, XRR, digital microscopy, PLM and SEM-EDS to elucidate the materials and technique of both artworks and find characteristic patterns that could indicate a relationship between both paintings and assist in correctly dating Climbing the hill. The technical analyses were supplemented with the historical information derived from the Liu family archives. The results showed that Climbing the hill was created in 1948 or 1949 on top of an earlier composition painted in Shanghai between 1933 and 1937. As for the companion View from St. John's Fort from 1948, the artist reused an earlier painting created in France in 1931. The analytical methods suggested that Liu Kang used almost identical pigment mixtures for creating new artworks. However, their painting technique demonstrates some differences. Overall, this study contributes to the understanding of Liu Kang's painting materials and his working practice.
