Witnesses will be exposed to a variety of misinformation after the witnessing of the event and state at the scene of the investigation after the delay period. This study was conducted to promote correct recall reporting without being affected by factors that against correct recall. Self-Administered Interview(SAI) is known to obtain eyewitness accounts quickly and accurately. Therefore, we performed a SAI to see if it reported more information than the control group that did not perform the SAI. Also, it also performed that correct information was maintained without being affected by misinformation and delay. Eighty-eight participants were asked to perform SAI or game after showing a video of mock crime. Misinformation was presented in the first or second session to see if it affected recall. An analysis of responses from the final test conducted in the second session by participants showed that groups that conducted SAI after a four-week delay reported more correct information than control groups, while there was no difference between incorrect- and confabulation information. In particular, the timing of presenting misinformation did not affect the amount of recall. This suggests that conducting the SAI immediately after witnessing the event protects correct information even after four weeks. Finally, the significance and limitations of this study, and subsequent studies were discussed.

We investigated the neural correlates of accurate eyewitness memory retrieval using functional near-infrared spectroscopy. We analyzed oxygenated hemoglobin ($HbO_2$) concentration in the prefrontal cortex during eyewitness memory retrieval task and examined regional $HbO_2$ differences between observed objects (target) and unobserved objects (lure). We found that target objects elicited increased activation in the bilateral ventrolateral prefrontal cortex, which is known for monitoring retrieval processing via bottom-up attentional processing. Our results suggest bottom-up attentional mechanisms could be different during accurate eyewitness memory retrieval. These findings indicate that investigating retrieval mechanisms using functional near-infrared spectroscopy might be useful for establishing an accurate eyewitness recognition model.

Ethyl glucuronide (EtG) and ethyl sulfate (EtS), which are ethanol metabolites, are direct indicators of ethanol intake; they have been studied in a variety of biological samples in forensic science. It is necessary to analyze ethanol metabolites to determine whether the ethanol detected in autopsy cases was due to alcohol consumption before death or due to the ethanol produced from post-mortem decay. In general, EtG and EtS are detected in the blood together with ethanol; however, it may be difficult to secure blood depending on the extent of decay. Therefore, the aforementioned method should be replaced by detecting the ethanol metabolites using tissue biological samples. In this study, we determined the optimal experimental conditions for detecting EtG and EtS from spleen samples using Liquid Chromatography - Tandem Mass Spectrometry (LC-MS/MS). Herein, the test method was validated, and an analysis method was applied to the actual autopsy cases.

The study was carried out to investigate the ratio of ethanol to n-propanol in blood and urine specimens, and developed a method for distinguishing ingested ethanol from artifactual ethanol in urine samples. In case of no urinary ethanol was detected, the ratio of ethanol to n-propanol concentration was about 12~20 times higher than those of blood. Therefore, it might be a good method to determine whether the detected ethanol is from drinking or from microbial fermentation. During the metabolism of ethanol, the levels of the metabolite of serotonin (5-hydroxytryptamine, 5-HT) and 5-hydroxyindole-3-acetic acid (5-HIAA) were decreased, while 5-hydroxytryptophol (5-HTOL) was increased. The levels of 5-HTOL/5-HIAA in urine samples of drinking suspects were greater than 1, in that of no drinking suspects were less than 1.

Porosity paper evidence is encountered in case of forgery, kidnapping, fraud and terrorist activity. The present study was designed to evaluate the effect of three chemical reagents (Ninhydrin, 1,8-diazafluoren-9-one (DFO), Iodine fuming) to the quality of developed latent fingerprints on porosity printing papers and newspaper. In case of printing papers, print quality was better with Iodine fuming method than Ninhydrin and DFO treatment to developing latent fingerprints. Developing latent fingerprint on newspapers was achieved with Iodine fuming processing. The processing of Iodine fuming followed by DFO and by using blue light (orange red filter) exhibited better results with Iodine fuming. Enhancement of latent fingerprint detection image using Digital Imaging System was achieved.

물관리 주무부처인 국토해양부(이하 국토부)는 최근의 전 세계적인 기후변화와 더불어 유역의 도시화 등으로 인해 급격한 하천환경 및 사회적 여건변화에 맞추어 "하천법"을 전부개정(법률 제8338호)하여 2008년 4월 7일부터 시행하고 있다. 개정 "하천법"에서는 하천수 사용 관리 조정기능이 크게 강화되어 국가 및 지방하천에서 하천수를 취수하여 특정용도로 사용하려는 경우, 그 취수량에 관계없이 누구나 관할 홍수통제소장에게 허가를 받아야한다. 따라서 국토부 소속기관이자 국가 물관리 전문기관인 홍수통제소는 수문조사, 이수(하천유량 관리 등) 및 치수(홍수예보 등) 등의 주요업무 중 기존 국가하천에 국한되었던 하천수사용 관리를 지방하천까지 확대하게 되었다. 본 연구에서는 하천법에 따라 집행된 2009년 국가하천, 지방하천 및 일시적인 하천수 사용 인 허가 행위 등 하천수관리 현황자료를 조사 정리하였다. 현황 자료를 토대로 행정구역(시 도)별, 수계별, 용도별, 허가량별, 월별 분석을 수행하고 그 특성을 파악하였다. 그리고 일시적인 하천수사용은 상기 분석 이외에 하천등급별, 공사종별 분석을 수행하였다. 2009년 총 152건(반려, 취소 등을 제외한 행위는 총 131건 : 국가하천 43건, 지방하천 33건, 일시적인 하천수 55건)의 기본적인 통계분석을 통하여 낙동강유역의 하천수사용 특성을 제시하고, 파악된 하천수사용 특성 결과는 낙동강유역의 물관리정책에 소중한 기초자료로 활용될 것으로 판단된다.

We can say that there are several majors in the course of cartoon education of college; cartoon, manpyung, 4 panel comic strips, editorial cartoon, webtoon and so on. Among them, this study starts with concrete question; "How can we encourage students to understand 4 panel comic strips better in the educational course of 4 panel comic strips?" 4 panel comic strips divided into two groups, depending on the materials. The first is daily cartoon which depicts the emotion in daily life. The second is editorial cartoon which deals with the problems of society in the ironical and witty way. Judging from my own thoughts that it would be better in the understanding and analysis of structures to take editorial cartoon in which materials are confined to social problems, this study treats rhetoric expression and structures of 4 panel comic strips. Introduction, development, turn and conclusion of "Jangdori" on Kyunghyangsinmoon are good materials for this study. So, "Jangdori" is in the center of this study. The objective of this study is to provide knowledge in creating 4 panel comic strips with the understanding the area of 4 panel comic strips through the analysis of the rhetoric expression and structures of this field. Even though this study has a limit, no access to daily 4 panel comic strips, I hope that this study would be a little help in any places in which the education of 4 panel comic strips is needed as a part of a course of cartoon in college.

This thesis aims to recall the importance of language in comics by studying comic strips in Korean daily newspapers: the comic strips are analyzed for rhetorical puns in its language text as they representatively show the value and role of language in comics. Moreover, Korean comic strips, as they developed into current affairs comics, acquired a stronger media characteristic of communicating information compared to other genres of cartoons. As a result, comics strips have become a genre where language plays an important role and the words needing to be able to convey the meaning quickly and implicitly. Due to tight control of national authority, the language technique developed into an indirect expression rather than a stronger direct imaging technique. The political oppression of the comic strip paradoxically brought on the rhetorical development in the creative techniques. Based on this analysis, the writer studied the rhetorical puns of the texts Korean comic strips by implementing the classification techniques of rhetoric expressions. As a result, through quotes and analysis of actual comic strips, the writer confirmed that Korean comic strips do actually show tremendously vast rhetorical puns in its language application techniques. The writer was also able to conclude that the rhetorical puns in comics were the force entertaining and impressing the readers, and also acting as the creative principle. Concluding this study, the writer emphasizes that language, not only in comic strips, is a combination of words and images and is also an important factor in all cartoons in general. Thus the thesis proposes that the training of humanistic thoughts and linguistic sensitivity are as important as learning to draw in the creation of cartoons.
