Staphylococcus aureus is an important cause of human infections, and it is also a commensal that colonizes the nose, axillae, vagina, throat, or skin surfaces. S. aureus has increasingly been recognized as a cause of severe invasive illness, and individuals colonized with this pathogen are subsequently at increased risk of its infections. S. aureus infection is a major cause of skin, soft tissue, respiratory, bone, joint, and endovascular disorders, and staphylococcal bacteremia may cause abscess, endocarditis, pneumonia, metastatic infection, foreign body infection, or sepsis. The authors describe a case of a fisherman who died of sepsis on a fishing boat during sailing out for fish. The autopsy shows paravertebral abscess, pus in the pericardial sac, infective endocarditis with vegetation on the aortic valve cusp, myocarditis, pneumonia and nephritis with bacterial colonization, and also liver cirrhosis and multiple gastric ulcerations.

Psoralen(7H-Furo［3.2-g］ ［1］benzopyran-7-one) and angelicin(2-Oxo-[2H]- furo[2.3-h]-1-benzopyran) are angular furocoumarin with diverse photobiological effects. They are major components of Psoralea corylifolia L.(破古紙). Psoralea corylifolia L. is used for a tonic and nursing one's energy. It can be also used for loss of virility. vitiligo. a skin disease, etc.. But a well known and often appreciated side effects f psoralens is the hyperpigmentation caused by this treatment. A women who used the herbal drug-mixed-medicine named'sobaeksu' to treat her vitiligo made a complaint against the orinetal medical doctor. She complained that her skin got burned to 2nd degree by the liquid. 'sobaeksu' through a medical celtficate. So we analyzed the components of that liquid with gas chromatography and gas chromatography/mass spectometry. It has 57.3% ethyl alcohol and two kinds of psoralens. Psoralens were psoralen and angelicin and each one of their contained quantity was 0.128mg/ml and 0.123mg/ml.

Data mining is an information extraction activity to discover hidden facts contained in databases. Using a combination of machine learning, statistical analysis, modeling techniques and database technology, data mining finds patterns and subtle relationships in data and infers rules that allow the prediction of future results. Typical applications include market segmentation, customer profiling, fraud detection, evaluation of retail promotions, and credit risk analysis. Law enforcement agencies deal with mass data to investigate the crime and its amount is increasing due to the development of processing the data by using computer. Now new challenge to discover knowledge in that data is confronted to us. It can be applied in criminal investigation to find offenders by analysis of complex and relational data structures and free texts using their criminal records or statement texts. This study was aimed to evaluate possibile application of data mining and its limitation in practical criminal investigation. Clustering of the criminal cases will be possible in habitual crimes such as fraud and burglary when using data mining to identify the crime pattern. Neural network modelling, one of tools in data mining, can be applied to differentiating suspect's photograph or handwriting with that of convict or criminal profiling. A case study of in practical insurance fraud showed that data mining was useful in organized crimes such as gang, terrorism and money laundering. But the products of data mining in criminal investigation should be cautious for evaluating because data mining just offer a clue instead of conclusion. The legal regulation is needed to control the abuse of law enforcement agencies and to protect personal privacy or human rights.

The purpose of this study is to examine the effect of police investigation environment on perception toward legalization of private investigation. To enhance the completeness, this study conducted a survey on police officers in service and analyzed the survey data through statistical technique. The results for examination on how police investigation environment influence on perception toward legalization of private investigation were as follows. When the 'work burden from long-term cold case' composing the police investigation environment is high, the police officer highly evaluated the growth potential of private investigation, showed positive perception toward private investigation market, and showed intention for re-employment at private investigation agency after retirement. When the police officer experiences more difficulties from 'investigation other than criminal case', the police officer highly evaluated the growth potential of private investigation and showed intention for re-employment at private investigation agency. In addition, when the police officer thinks that there are a lot of difficulties for "Limited investigation on specialized area", the police officer showed positive perception toward growth potential of private investigation and private investigation market. In addition, police investigation environment showed significant result on legalization of private investigation. The result also verifies that as the difficulty of crime investigated by the police is getting higher quantitatively and qualitatively, it is necessary to introduce private investigation system which is specialized and able to investigate for a long time. This study hopes that this study result would be utilized as the grounds in signing the bill for introducing the private investigation system.

In this study, I set the allowable range of viewing / copying rights of investigation records on criminal victims and bereaved families in the procedure of investigation. I tried to grasp the contents of the suspect's statement at an early stage and support it in order to cope appropriately Recently, the social consideration of people suffering from crime victims is expanding in fact. The scope of the investigation is set by the lawyer of the suspect in relation to the subordinate statute concerning the investigation and reading of the investigation record. In parallel, it is necessary to apply to the victim's lawyer or bereaved. This is a part that coincides with the purpose of certifying private rights such as browsing of litigation records to the victim and ultimately has a purpose related to the allowable range. Although it is the right to receive the investigation result at each stage, it is not used properly. Especially when distorted investigation progresses, if the suspect is not prosecuted, the victim may be in a state of regret. The important part can be summarized as the question of whether the investigation of the victim's lawyer is allowed to view and access the criminal records. This section has been reviewed with a focus on the current Act and its functional aspects should be emphasized and revised in accordance with the legal environment. These findings will contribute to ensuring victims' rights in the future. It is also used as an important resource in the legislative process, including the revision of the criminal procedure law.

The Moon Jae-in administration insisted on reforming the prosecution for the reform of power institutions, and also tried to control the power of the prosecution through the establishment of a high-ranking public officials criminal investigation office. Then, what is the direction of the legal prosecution reform? Above all, it is a logic to drastically reduce the power of the prosecution. How to shrink it? First, it is necessary to control or check the power of prosecution and investigation that the prosecution has. Second, the key to the reform of the prosecution is perhaps to separate personnel rights from power. In order to exclude external pressure from the prosecution's personnel rights, there must be no instruction or intervention from the attorney general. To do this, the prosecutor general must go through various personnel evaluations, such as multi-faceted evaluation. Third, the essence of the High-ranking Officials Criminal Investigations Act is to deal with crimes of prosecutors, judges, police, and members of the National Assembly. It is also the core of the institutional mechanism to cover the corruption of one's family members while holding all the right to investigate, prosecution, and warrant claims, and to check the omnipresent prosecutors who have abused their right to investigate for political purposes. Then, what is necessary for the success of the high-ranking officials criminal investigation office? Above all, We think political neutrality is very necessary. The Ministry of Airborne has a very high authority of the Director. This paper intends to examine the functions and roles of the prosecution and high-ranking officials criminal investigation offices to prevent corruption. We analyzed the contents of the prosecution and the public officials criminal investigation office, and examined the limitations and problems, and the measures to control corruption in public offices.

최근 지구온난화에 따른 기후변화로 시공간적으로 매우 불규칙한 강우가 발생하고 있으며, 홍수피해 및 극심한 가뭄으로 수자원개발 및 관리 환경이 더욱 어려워지고 있는 실정이다. 특히 우리나라는 하천수사용허가 기준유량의 원천이 되는 강수량의 계절별 편차가 매우 크고 연 강수량의 2/3 이상이 여름철에 집중된다. 하천수사용허가 기준유량은 하천유지유량이 고시되지 않은 지점은 10년 빈도의 갈수량인 기준갈수량과 같고, 하천유지유량이 고시된 지점은 기준갈수량에서 하천유지유량을 감한 양이다. 하지만 하천 유량의 변동성이 계절에 따라 매우 큼에도 불구하고 갈수기의 한정적인 기준갈수량으로 연중 전 기간의 하천수사용허가 기준유량을 설정하면 가용한 하천수량을 과소 산정할 우려가 있다. 따라서 계절성을 고려하여 기간에 맞는 기준갈수량을 산정하는 것이 안정적인 하천수의 사용과 하천관리에 필요한 유량을 효율적으로 관리할 수 있을 것으로 판단된다.본 연구에서는 효율적인 하천수사용허가 기준유량을 검토하기 위해 지역별 계절성을 고려한 갈수량 검토를 실시하였다. 갈수량 산정을 위한 자연유량은 TANK모형을 이용하여 우리나라 112개 중권역에 대해 50년 간 일별 자연유량을 모의하였다. 모의된 자연유량을 바탕으로 112개 중권역에 대해 유황분석을 실시하여 평균갈수량과 기준갈수량을 검토하였으며, 계절별 갈수량을 검토하기 위해 기간을 여름철(5~10월)과 겨울철(11~4월) 두 개의 시기로 구분하여 여름과 겨울 갈수량을 산정하였다. 또한, 계절성 분석을 위해 세 가지 계절성 지표를 검토하였다. 첫째, 여름과 겨울 갈수량의 비율인 SR(Seasonality Ratio), 둘째, 갈수량의 평균시기를 나타내는 주기적 계절성 지수 SI(Seasonality Index), 셋째, 갈수량의 월간 분포를 나타내는 SH(Seasonality Histogram)이다. 이러한 계절성 지표를 바탕으로 공간적 패턴을 분석하고 여름과 겨울 갈수량의 기초가 되는 수문학적 근거를 판단하였다. 따라서 유역의 계절성 지표를 바탕으로 기간을 분리하고 기간별 갈수량 검토를 통해 보다 효율적인 하천수사용허가 기준유량을 검토할 수 있을 것으로 판단된다.
