In this paper, it discusses about the stability of rock slope of pyroclastic rock, which can easily meet at construction site. Basically carry out the investigation about the development of a surface of discontinuity, too. With that, it refers to the basic groups of sedimentary rock, treats of general details about investigation of rock slope and stability analysis, and discusses general characteristics and stability analysis case study about rock slope of pyroclastic rock. Achieved basic geological investigation on rock slope of pyroclasic rock, and examine the stability of slope by doing limit equilibrium and geometric stability analysis due to the result of investigation. It is considered to be able to accumulate many data about slope design of pyroclastic rock hereafter estimating degrees of rock mass properties of pyroclastic rock quantitatively.

A Recently elevator accidents were occurred and increased due to carelessness of user and violent behavior. The accident of door detachment in elevator platform by electronic motor scooter show a example of safety concerns and insensibility for safety awareness. In this report, we review the cause of accident of door detachment in elevator platform by electronic motor scooter, and show some suggestions of preventing from the safety concerns about this case.

The basic concept of analysis of human error that induced railway accident is that errors are consequences, not causes. But in most cases, it is likely that direct causes of the accident could be concluded as real causes, which make it difficult to find out root causes. Design, training, staffing, culture and condition are general category applied to investigate human error. In order to examine how those approach could help accident analysis, this paper studied accident investigation reports of UK RAIB(Rail Accident Investigation Branch). Rather than consider specific investigation method, we focus investigation result on how to describe causal factors and how to indicate recommendations to prevent similar accident. The reports show that they try to find out causes more in organizational, environmental and job factors, which implies the necessity to improve investigation process of human error accident in Korea.

Landslide researches are divided to a method of interrelationship for various factors, method of predicting landslide possibility, and method of estimating landslide risk which are occurring landslides in the natural slope. Most of landslides occurred in natural slope are caused by a heavy rainfall in summer season. Weathered soil layer located in upper side of rock mass was occurred. As well as, they are announced to have an influence to geometry, geology, soil characteristics, and precipitation in the natural slope. In order to investigate and interpret the variety of landslides from field investigation to risk analysis, landslide analysis process due to geotechnical and geological opinions are systematically demanded. In this research, the study area is located in Macheon area, Gyeongsangnam-do and performed the landslide investigation. From the results of landslide investigation and analysis, optimized standard model based on natural landslide is proposed to high technical method of landslide investigation and interpretation.

소방서는 재난관리의 대응기관으로서 각종 현장에 출동하여 현장상황에 대한 많은 경험과 자료를 축적하여 화재예방 및 진압활동 등에 활용할 수 있음에도 불구하고 사고의 기록, 분석, 정보관리 등이 미흡한 실정이다. 이러한 사항을 보완하기 위하여 소방방재청에서는 화재조사팀을 주축으로 "국가 화재조사분류체계"를 혁신적으로 개선하였다. 본 연구에서는 소방서에서 수행하고 있는 기존의 화재조사 과정과 자료 취득 및 분석 과정을 살펴보고, 활용 방안을 제시함으로서 "국가 화재조사분류체계"의 운영에 필요한 기초 자료를 제공하고자 한다.

In this study, we peformed ahead a field geological investigation, boring investigation for slope stability analysis in large scale slope failure area. But the geological stratum was not clearly grasped, because ground was very disturbed by large scale Granite intrusion. Furthermore, the existing test data was not pertinent to the large scale Granite intrusion site like here. Therefore, various kind of field test were performed to grasp clearly for geological stratum. And the results of back analysis, various kind tests used to slope stability analysis.

The bus using compressed natural gas(CNG) trend to be extended in use internationally as optimal counter-plan for reducing discharge gas of light oil due to high concern about environment. But, Composit pressure vessels(CPV) to be equipped with CNG bus is always involved in the point that safety accidents happen due to having compressed natural gas. In this report, we analysis the cause of CPV bursting accident by reviewing design and manufacture factor and suggest preventive measure through this case.

We have analyzed the allele and genotype frequencies from 10 fractions of ancient human skeleton in 3 pieces of Jar coffin excavated from Naju Bokamni3rd tumulus by PCR amplification, high resolution polyacrylamide gelelectorphoresis and silver staining. We could isolate human genomic DNA from 3 bone fractions but the rest of them could not be used as materials due to being decayed. We could detect sex determination as male and 3 genotypes of STR system, HUMTHO1, HUMTPOX and HUMC5F1PO from the bone fraction of left side in Jar coffin 3 and see the slightly reaction suggesting the sex as male from the bone fraction of the left side in Jar coffin 2 and female from the right side in Jar coffin 3.We have also analyzed the genotype frequencies of mitochondria from the bone fractions of the left side and the right side in jar coffin 3, respectively. From the result of indetifiying at nucletide position between 16018 and 16378of the base of hyper variable region(HV1) in the control region, We can presume that the both bones have the same maternal inheritance.

법적시료(Forensic Evidences)로 사용되는 혈흔, 정액반, 타액반 및 모발을 DNA의 분리과정 없이 FoLT (Formamide Low Temperature) PCR법으로 DNA의 특정부위를 분석하고자 하였다. FoLT PCR법으로 3종류의 STR(Short Tandem Repeat) 좌위와 성별을 확인하는 Amelogenin gene을 PCR법으로 동시에 분석하기 위하여 formamide농도와 annealing온도를 검토한 바 최적의 formamide농도는 8%(v/v)이었고 annealing온도는 $48^{\circ}C$이었다. 그리고 1% Triton X-100을 이용하여 시료를 세척한 경우에 증폭 효율이 증가하였다. 따라서 FoLT-PCR법을 이용한 경우 DNA를 분리하기 위한 전처리없이 소량의 시료를 기존의 PCR법보다 빠른 시간내에 한번의 PCR 및 전기영동으로 HumTH01, HumTPOX, HumCSF1PO 및 Amelogenin을 동시에 분석할 수 있었다.
