DNA 포렌식에 의한 DNA 증거의 증거능력에 관한 고찰
김동준(Kim, DongJun),오경식(Oh, KyungSik) 한국피해자학회 2018 被害者學硏究 Vol.26 No.1
Advances in forensic DNA analysis have led to tremendous improvements in identifying and confirming perpetrators and victims. This has added credibility to DNA evidence, resulting in cases where criminals are more likely to be forced to own up to their criminality and culpability. This paper addresses scientific and technical theories the DNA analytical technologies are founded on as well as the suitability of individual analytical procedures. Beyond these issues, it went on to discuss the requirements that need to be met in order for DNA evidence, collected through forensic DNA testing, to be admissible in court in Korea. DNA testing results are presented in court in the form of certified expert testimony. And according to Article 313, “Statement, etc.” of the Criminal Procedure Act, as long as the DNA evidence offered is free from errors in laboratory procedures and concluding interpretations of the person responsible for producing the expert opinion recording, such procedures and outcomes will be admissible as legitimate evidence in court. In other words, the aforementioned expert testimony is nothing short of legislative intent at acknowledging the testimony as admissible in court, thus should not be understood as standards with which the scientific evidence concerned is admissible and tried at court. For this reason, admissibility in court of DNA evidence from DNA forensic analysis should not only be based on whether it meets the requirements as expert testimony, but also whether its theories of reasoning and analyses are founded on acceptable scientific principles. Furthermore, the tools and methods used in DNAprofiling need to be validated, allowing the analyzed result in question to be assessed for admissibility in criminal court. Trends of precedents regarding DNA evidence seem to require that the relevancy of DNA analytical theories, suitability of DNA analytical methods that have implemented these theories, and maintenance of the chain of custody of evidence by applying scientific procedures to the targets concerned, be met for the evidence to be admissible in court. Furthermore, it may be fair to say that within the structure of Korea’s criminal prosecution, the processes involved in determining whether or not DNA evidence is credible may be part of what is needed to assess its probative value. At the moment, theoretical foundations of DNA analysis are deemed reliable with the overall approval of scientific circles, however there are improvements made all the time in standard analytical methodologies and procedures regarding their implementation and analytical techniques. This has created an unbridgeable gap between common knowledge and the outcomes of scientific research activities that legal experts, particularly trial judges, are left with no choice but to be more and more dependent on expert testimony when they assess the credibility of DNA evidence. Still, the more weight DNA analysis carries, the more likely serious errors in laboratory testing occur; thus, there is increased emphasis on how to keep the chain of custody in determining the admissibility of DNA evidence, for example, the qualification of those involved in testing, sample collection and preservation, stability of the testing methods that have been utilized, and conformance to analytical procedures. Therefore, if there is evidence that is crucial in determining guilt in crime, and the continuity of its preservation is closely related to the presence and integrity of the evidence concerned, namely DNA evidence, the defendant should be afforded the opportunity for the credibility of evidence to be tried in court during the entire processes of such evidence being collected, stored and analyzed to: prevent wrongful accusations; to make court proceedings more impartial; and to comply with appropriate procedures. To this end, cross examination of witnesses, disclosure of extensive evidence of the parties involved, and cross examinat

김동준,윤준웅,지성현,최재형,이진선,김동수,Kim, Dong-Joon,Youn, Jun-Ung,Jee, Sung-Hyun,Choi, Jaehyung,Lee, Jin-Sun,Kim, Dong-Soo 한국지반공학회 2014 한국지반공학회논문집 Vol.30 No.1
모래지반의 지표면에 위치한 거친 바닥면을 가진 강체 연속기초와 원형기초에 대하여 수치해석을 이용하여 팽창각 변화에 따른 지지력계수 $N_{\gamma}$와 형상계수를 구하였다. 양해법(explicit method)에 기반한 유한차분해석을 이용하여 지지력계수를 산정하기 위한 수치모델과 해석절차를 개발하고, Mohr-Coulomb 소성모델을 이용하여 다양한 내부마찰각(${\phi}$)과 팽창각(${\psi}$) 범위에 대하여 지지력계수를 도출하였다. 팽창각이 감소됨에 따라 지지력도 감소하는 것으로 나타났으며, 보편적인 지지력계수 제안식들이 가정하고 있는 관련흐름법칙(associated flow-rule)이 적용된 경우(${\psi}={\phi}$)를 기준으로 비관련흐름법칙(nonassociated flow-rule)이 적용된 경우(${\psi}$ < ${\phi}$)의 상대적인 지지력 비율을 산출하였고, 일반적인 모래에 대한 관계식을 제안하였다. 원형기초의 형상계수는 연속기초의 평면변형률 조건의 고려 여부에 따라 크게 변하였으며, 평면변형률 조건을 고려하여 내부마찰각을 증가시킨 경우가 기존의 실험 결과와 유사한 경향을 나타내었다. 형상계수 제안식들의 경향이 차이를 나타내는 원인에 대하여 고찰하고 설계시 적용 방안을 제시하였다. Bearing capacity factor $N_{\gamma}$ and shape factor were studied for rigid strip and circular footings with a rough base on sand by numerical modelling considering the effect of dilation angle. The numerical model was developed with an explicit finite difference code. Loading procedures and interpretation methods were devised in order to shorten the running time while eliminating the exaggeration of the reaction caused by the explicit scheme. Using the Mohr-Coulomb plasticity model with associated (${\psi}={\phi}$) and nonassociated (${\psi}$ < ${\phi}$) flow-rules, the bearing capacity factor $N_{\gamma}$ was evaluated for various combinations of internal friction angles and dilation angles. Bearing capacity factor decreased as the dilation angle was reduced from the associated condition. An equation applicable to typical sands was proposed to evaluate the relative bearing capacity for the nonassociated condition compared to the associated condition on which most bearing capacity factor equations are based. The shape factor for the circular footing varied substantially when the plane-strain effect was taken into account for the strip footing. The numerical results of this study showed closer trends with the previous experimental results when the internal friction angle was increased for the strip footing. Discussions are made on the reason that previous equations for the shape factor give different results and recommendations are made for the appropriate design shape factor.

급속열처리시 Ta-silicide박막 형성에 미치는 불순물 인의 영향
김동준,강대술,강성군,김헌도,박형호,박종완,Kim, Dong-Jun,Gang, Dae-Sul,Gang, Seong-Gun,Kim, Heon-Do,Park, Hyeong-Ho,Park, Jong-Wan 한국재료학회 1994 한국재료학회지 Vol.4 No.8
Polycide구조로서의 Ta-silicide박막을 제작하고 Polysilicon기판에 주입된 불순물 양의 변화가 Ta-silicide형성에 미치는 영향을 조사하였다. RTA처리시 Ta silicide상은 불순물 양의 증가($1 \times 10^{13}\to 5 \times 10^{15}$/ions/$\textrm{cm}^2$)에 관계없이 $800^{\circ}C$에서 형성되기 시작하여 $1000^{\circ}C$이후 안정한 silicide박막을 형성하였다. 그러나 XRD분석결과 불순물 양이 증가할수록 Ta-silicide상의 intensity는 감소하는 경향을 나타내었고 또 SEM(cross sectional view)분석결과 silicide 형성초기온도인 $800^{\circ}C$에서는 불순물 양이 많은 시편에서 silicidation이 활발히 진척되지 못하였음을 관찰할 수 있었다. 이후 열처리 온도가 증가하면서 이러한 차이는 적어져 $1000^{\circ}C$에서는 불순물의 증가에 따른 영향이 미세해짐을 알 수 있었다. 따라서 주입된 불순물 양의 증가($1 \times 10^{13}\to 5 \times 10^{15}$/ions/$\textrm{cm}^2$)는 Ta-silicide형성시 고온에서는 큰 영향을 미치지 못하나 silicide형성초기온도에서 silicidation을 감소시키는 것으로 생각된다. Ta-silicide films in polycide structure were prepared by rapid thermal annealing of sputtered Ta film on poly-Si and doped poly-Si. Effects of phosphorus on Ta-silicide formation were investigated. Independent of the ion dose($1 \times 10^{13}\to 5 \times 10^{15}$/ions/$\textrm{cm}^2$), Ta-silicide phases were formed at $800^{\circ}C$ and stabilized above $1000^{\circ}C$. From the result of XRD at $800^{\circ}C$ and $900^{\circ}C$, however, it was indicated that the more the doping concentration the weaker the intensity of Ta-silicide phases. Furthermore, the observation of SEM revealed that the increase of the doping concentration retarded silicidation. As the temperature increased, the dopant effect was weakened gradually and almost disappeared at $1000^{\circ}C$. Therefore the variation of the ion dose from ($1 \times 10^{13}\to 5 \times 10^{15}$/ions/$\textrm{cm}^2$) did not greatly affect the formation of Ta-silicide at high temperatures but retarded slightly the silicidation at low temperatures.

Motor vehicles are the major source of environmental air pollution through the combustion of lead-containing gasolines. People who live in the areas with heavy traffic usually have the higher blood lead levels. This study was to investigate the lead level between the maternal blood and their infants cord blood. Immediatly after Placental delivary, the sampls of cord blood and maternal venous blood were obtained randomly from 14 infants whose mothers had spent their entire pregnancy in Seoul. Lead concentration was determined by the dithizone method. The results obtained were summarized as follows: 1. Hemoglobin, Hct and RBC were significantly higher in cord blood than in the maternal blood, by 36%, 54.9%, 36.9% respectively. 2. MCV in cord blood was higher than that in maternal blood by 13.8%. But MCH and MCHC were lower than those in maternal blood, by 9.7%, 3.3% respectively. The differences were statistically significant. 3. Lead concentration of cord blood $(23.93\;{\mu}g%)$ was higher than that in maternal blood $(21.93\;{\mu}%)$ by 9.1%.

The present study was undertaken to determine the effect of xylazine-pentobarbital anesthesia on the gastroduodenal transit time of barium sulfate and whether this condition can be antagonized by yohimbine, 4-aminopyridine and yohimbine+4-aminopyridine in dogs. Xylazine-pentobarbital anesthesia prolonged the gastroduodenal transit time to $121.50{\pm}21.25$ minutes compared with $5.25{\pm}0.90$ minutes of control. Yohimbine and yohimbine+4-aminopyridine reversed $121.50{\pm}21.25$ minutes of transit time of anesthetized dog to $25.25{\pm}6.83$ and $63.25{\pm}15.69$ minutes, respectively. 4-aminopyridine alone, $115.75{\pm}$18.35 minutes, was not effective in reversing the xylazine-pentobarbital-induced prolongation of gastroduodenal transit time. Yohimbine was the most effective for reversal of xylazine-pentobarbital-induced prolongation of gastroduodenal transit time in dogs.

This paper describes an EEG(electroencephalogram) software for two-channel cerebral function monitoring system to detect the cerebral ischemia. In the software, two-channel bipolar analog EEG signals are digitized and from the signals various EEG parameters are extracted and displayed on a monitor in real-time. Digitized EEG signal is transformed by FFT(Fast Fourier transform) and represented as CSA(compressed spectral array) and DSA(density spectral array). Additional 5 parameters, such as alpha ratio, percent delta, spectral edge frequency, total power, and difference in total power, are estimated using the FFT spectra. All of these are effectively merged in a monitor and displayed in real-time. Through animal experiments and clinical trials on men, the software is modified and enhanced. Since the software provides raw EEG, CSA, DSA, simultaneously with additional 5 parameters in a monitor, it is possible to observe patients multilaterally. For easy comparison of patient's status, reference patterns of CSA, DSA can be captured and displayed on top of the monitor. And user can mark events of surgical operation and patient's conditions on the software, this allow him jump to the points of events directly, when reviewing the recorded EEG file afterwards. Other functions, such as forward/backward jump, gain control, file management are equipped and these are operated by simple mouse click. Clinical tests in a university hospital show that the software responds accurately according to the conditions of patients and medical doctors can use the software easily.
