This study explores the way of prescribing the ethic of science in korean society in the 2004 ethical debates about 'Hwang woo-suk' embryo stem-cell study. It is the process of ethical communication. The debate includes very sensitive problem such as ovum and embryo, which is related directly with life. Particularly, this issue has many implications as there was a wild enthusiasm of patriotism in Korean society after had published Prof. Hwang's paper. This case shows dramatically the formation of ethical attitude in our society. There were included many actor's desire, interest, and conflicts. This study analyzes the process of competition to seize the initiative of the definition of ethics. It includes patriotic discourse, competition of rhetorics. This ethical communication involves the making of 'star scientist', Hwang woo-suk. In consequence, the ethics has been marginalized and stigmatized as anti-science on the stage of star scientist. This study argues ethics is not a fixed thing, it is construction of competition.

Police officers in charge of investigating sexual assault cases are likely to have suspicions in the process of investigation to find out the truth about the case, which leads to secondary victimization to the victims, and these concerns are often unveiled as social problems. This study suggested the research question that what the causes of secondary victimization derived from the police officers in charge of sexual assault investigation are. The purpose of this study was to contribute to the restoration of the trust of the police by preventing or minimizing the secondary victimization of sexual assault cases in the investigation process. Among the personal characteristics of police officers, rape myth, tolerance n violence and hostile gender discrimination influenced suspicion and prejudice, and rape myth and hostile gender discrimination affected the lack of sensitivity. Among the workplace-related characteristics, the duration of employment and experience in sexual assault cases affects the lack of sensitivity. In addition to the revision of the law and the improvement of the system of sexual assault, the prejudice against the sexual assault inherent in the attitudes and behaviors of the police officers in charge of the sexual assault cases should be improved.

In order to properly manage the river water use, it is necessary to collect reliable data of river water use. However, It is not easy to get credible river water use data in Korea because there are some difficultites in reporting and measuring river water use data. Thus, Han River Flood Control Office has installed and operated measuring facility using V-ADCP on the EOUBO intake open channel in the Gosan-Bongdong station section of the Mankyung river, where the use of agricultural water is large. In this study, the applicability of the V-ADCP velocity profile method was evaluated for real-time river water use. For this reason, the parameter sensitivity of Chiu's 2D velocity distribution equation was analyzed and the optimal parameters based on actual discharge data were calculated. In addition, the characteristics of the velocity profile method were analyzed by comparative evaluation of the rating curve method and the index velocity method.

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.

In this study, I analyzed what rhetorical citation type students most frequently used when reinforcing logic of their opinions and arguments in research papers, and compared these rhetorical types between higher and lower Korean proficiency levels of students. These 30 student papers included the following rhetorical citation types: statistics, attribution, exemplification, statement of use, establishing connections between sources, and comparing one's own findings or interpretations with other sources. Statistics was the most frequently used rhetorical citation type. In addition, the group with the highest level of Korean proficiency used citations about 8 to 11 times in their papers, and incorporated a variety of citation types including attribution, statistics, exemplification, and statement of use. Lower level students used significantly less citations and citation types. Therefore, it is necessary to raise awareness that "citations" is an important strategy to reinforce one's own logic, teach various types of citations as important research writing strategies, and prepare a more citation-focused academic writing curriculum.

The purpose of this study is to investigate the difference in advertising effect of visual rhetoric type of Facebook ads depending on the user sensitivity and level of empathy. The experiment was designed as a between-subjects factorial design (visual rhetoric type) × 2 (brand sensitivity) × 2 (level of empathic understanding). The results of the experiment performed to analyze the strategies of Facebook ads for ads effectiveness can be summarized as follows: a three-way interaction effect for persuasive effects was found among the type of visual rhetoric, brand sensitivity, and empathic understanding for both types of visual rhetoric. Breaking down it by type of rhetoric, no interacting effect was observed between brand sensitivity and empathic understanding levels for the visual simile ads in most of the dependent variables. For the visual metaphor ads, however, the brand sensitivity and empathic understanding levels were found to have interaction effect in all dependent variables.

하천수 사용량 자료는 하천법에 따라 사용자가 월단위로 사용량(농업용수 8,000m³/s 이상)을 한강홍수통제소 하천수사용관리시스템에 직접 입력 또는 우편이나 공문 등으로 전달되어 입력되고 있다. 하지만 현재와 같이 월단위로 수집되는 자료로는 하천수 사용량 통계자료 분석이나 효율적인 물관리를 위한 하천 유량 관리에는 활용에 한계가 있어 정확한 하천수 사용량 관리가 어렵다. 따라서, 본 연구에서는 현장에서 계측되어 표준화된 자료로 전송되는 자료를 현재 한강홍수통제소에서 운영중인 첨단 계측장비를 이용해 하천 유량 자료를 실시간으로 수집 및 관리하고 있는 IRDiMS(Integrated Real-time Discharge Measurement System)를 활용하여 하천수사용관리시스템에 하천수 사용량 자료를 실시간으로 입력하도록 개선방안을 제시하고자 하였다. IRDiMS는 계측장비를 통해 하천 유량 자료를 수집하여 품질관리를 거쳐 하천의 유량자료를 관리하고 있어 실시간 하천수 사용량 자료는 IRDiMS 의 처리체계를 동일하게 활용할 수 있다. 또한 IRDiMS에서 처리된 자료는 물리적·소프트웨어 측면에서 한강홍수통제소 내부DB와 같은 공간에 위치하여 자료를 하천수사용관리시스템 외에도 국가수문DB 및 타시스템에 연계하는데 유리하다. 실시간 기반의 하천수 사용량 자료는 현장에서 실시간으로 계측되어 산정된 하천수 사용량 자료를 일정한 형식에 따라 10분 주기로 IRDiMS의 수신서버로 전송하고 수집된 자료를 처리서버에서 품질관리를 거친 후 자동유량DB에 저장된다. 저장된 자료는 정해진 규칙에 따라 국가수문DB로 자동 연계하고, 실시간으로 외부망에 있는 연계서버를 통해 하천수사용관리시스템DB에 자료를 저장하도록 하천수 사용량 수집에 대한 방안을 마련하였다.

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.

In forensic genetics, when it is not possible to confirm an individual's identity through STR profile analysis, additional information about the individual can be obtained using DNA-based phenotypic traits estimation. Recently, various researches have been conducted on methods to determine externally visible characteristics (EVC) such as eyes, hair, and skin color. However, relying solely on such phenotypic traits information has limitations for application in East Asian regions, including Korea. In this study, in order to utilize EVC related to an individual's appearance as investigative information, SNPs related to eye shape, hair thickness, skin color, as well as baldness, body type, high myopia, facial shape, acne, and behavioral habits were explored. A total of 50 SNPs were selected, and a targeted amplicon NGS panel capable of amplifying them all at once was developed. Experimental results confirmed the allelic types and frequencies of the 50 SNPs in 14 samples. We plan to use this panel to investigate the correlation between genotype and phenotype using various samples, and to develop methods for interpreting the results.
