The characteristic of the water quality and pollutant discharge was analyzed at the units watershed of the total amount management in Han-river basin, and after classified in a similar area by multivariate statistical analysis, the main trend such as the water quality trend and pollutant discharge characteristic were analyzed. As a result of this study, the density of the pollutant at the unit watershed is not necessarily identified as discharge density, and the primary management watershed and targeted substances were analyzed depending on the operating status of the environmental infrastructure in watershed and the main pollution factor and discharge path per pollutants. As a result of cluster analysis, watersheds were classified into four groups according to discharge characteristics. It will be used when selecting target area of primary management that is appropriate to the characteristics of each river and establishing efficient water quality improvement plans.

현재, melamine은 레진, 내화제, 접착제, 라미네이트 등 우리 생활에 다양하게 사용되고 있다. 그로 인해 melamine이 포함된 폐수의 수계 유입 또한 증가하고 있다. EU안전지침서의 GHS에는 melamine을 암 유발 가능성이 있는 물질로 구분하고 있다. 하지만 아직까지 melamine에 대한 독성연구는 진행 중이며 어떤 영향을 주는지 아직까지 밝혀진 사실이 적다. 본 연구에서는 한강과 주변하천의 melamine 오염 정도를 HPLC/UV를 이용하여 오염 정도를 파악하였다. 그리고 활성탄을 이용한 흡착실험 및 모델링에 관한 연구를 하였다. 우선 한강수계 중 상대적으로 상류에 있는 팔당댐 근교와 그보다 하류지역인 뚝섬유원지에서 동일한 시료를 3개씩 채수하였고 한강에 유입되는 하천 중 홍릉천, 왕숙천, 청계천에서 동일하게 시료를 채수하여 정제 후 melamine 농도를 측정하였다. 그 결과 팔당댐 근교의 시료에서는 melamine이 검출되지 않았으며 그보다 상대적으로 하류인 뚝섬유원지에서는 0.312 μg/L농도가 검출되었다. 왕숙천에는 0.578 μg/L로 가장 높았으며 청계천과 홍릉천은각 0.197 μg/L, 0.325 μg/L로 검출되었다. 전체적으로 낮은 농도지만 대부분의 지점에서 melamine의 검출을 확인할 수 있었다. 1970년대에는 melamine 생산량이 200,000 ton에서 최근에는 1,400,000 ton으로 계속적인 사용의 증가로 수계오염은 심화될것으로 보인다. 활성탄을 이용한 흡착 실험에서는 활성탄 크기에 따라 melamine흡착에 약간의 차이를 보였으나 파과모델과 어느 정도 일치함을 보였다. Currently, melamine is being used variously in our lives such as resins, flame retardants, adhesive, laminate etc. And understandably sewer of stream of wastewater containing Melamine has also increased. GHS (Globally Harmonized System of Classification and Labelling of Chemicals) of EU safety guidelines says that it can cause cancer. Still, study on toxicity of Melamine is going on. In this research, melamine contamination level of the Han River and River Basin was analyzed by HPLC/UV. And the experiments of GAC adsorption were conducted and the model was studied. We collected the 3 same samples at the suburbs of Paldang Dam located in the relative upstream in Han River and Ttukseom amusement park, the downstream region and collected samples equally at the Hongreung stream, Wangsuk stream, Cheonggye stream among streams flowing into Han River and then measured Melamine concentration after purification. As a result, melamine was not detected at the suburbs of Paldang Dam and it was detected at Ttukseom amusement park, the downstream of it, in the concentration of 0.312 μg/L. The Wangsuk stream with 0.578 μg/L highest Cheonggye stream and Hongreung stream was detected with each 0.197 μg/L and 0.325 μg/L. Although the concentration was low in general, melamine detection could be checked at most point. In 1970, the world capacity of Melamine was estimated at 200,000 ton, with current production estimated to be 1,400,000 ton. Melamine of Han River and rivers flowing into Han River is present at low concentration but pollution will increase in the future due to increase of use. Depending on the size of activated carbon in the experiment were slightly different. But the breakthrough model is almost identical.
형사정책학회 창립 30주년 기념논문 : 한국형사정책학회 창립 전후 -회고와 전망

Korean Association of Criminology[KAC] was founded in 1985. Prof. Lee Soo Sung, Seoul National University, initiated its founding, and led it for first four years as its president. In order to advance interdisciplinary studies, he gathered academic scholars who were professionally trained from sociology, psychology, and criminal law. Legal practitioners on criminal justice became another partners as KAC members. From the initial period, KAC was a melting ground for multiple fields academics and for theoretical-practical professionals. Since 1986, Korean Journal of Criminology[KJC] was published on the annual basis, and is now advanced to be published three times annually. Various topics were covered at KJC. Sometimes, ex-offenders who were imprisoned for long-term period were invited, and made a presentation on their actual experience inside the wall. Now, KJC is proud of one of the highest impact factor journals among law field. In the near fututre, KAC is expected to be center for critical debates and really interdisciplinary studies. KAC’s founding statement in 1985 says; Science and human rights should be the two pillar for criminology and criminal justice. Policy without science tends to be blind and convenient, and the policy without human rights takes people as a object of oppressive control. Such a statement is of course valid in the present time.

Korea has maintained the professional-career judge system without any kind of lay participation in the trial. Since 2004, the Special Committee on the Judicial Reform discussed the introduction of a jury system-albeit as a form of weak participation. Now, the draft on the criminal jury system is awaiting a legislative review at the National Assembly. My question here is what kind of changes will be enforced if Korea introduce the criminal jury system. Police witness will often appear to the criminal trial. Police will stand in front of jury panel, and witness what he has experienced. Police is concerned with how to secure the reliability of his witness. His attitude or even his fashion would work as an influencing factor on the reliability. More important factor would be whether a witnessing police should maintain a distance from the prosecutor If a jury consider that a police witness was instructed/controlled by his supervising prosecutor, his testimony would be far from convincing. Such a new situation will require the new structure of police which will be more responsible for their investigation, and more independent from the prosecutor. Public prosecutor will much more concentrate on the trial than deeply involve in a direct investigation. Public prosecutor will focus their authority on the supervision of due process, and rather than the direct investigation. Police will gain the authority to commit an primary investigation under his own responsibility, and will be put under stronger pressure to the due process of law. The possible changes in the police work and criminal justice system in general would be more desirable because they will seek more justice and more human rights.
