The fractal-based method for describing rubbed surface texture has aroused great interest. The determination of rubbed surface topography is believed to be extremely important in the areas of contact mechanics, adhesion and friction. In order to describe topography of the rubbed surface, the wear test was carried out with annular surfaces of wear testing specimens in dry friction. furthermore, the relation between the fractal dimensions and the frictional conditions are also investigated and fractal descriptors was applied to rubbed surface with image processing. Fractal dimension can be determined by sum of intensity difference of image surface pixel. Fractal dimension increased according as the applied load and sliding distance increase. Topography of the rubbed surface can be effectively obtained by fractal dimensions.

End-milling have been widely used in aircraft, automobile part and moulding industry. However, various working factors such as spindle speed, feed rate and depth of cut in end-milling have an effect on spindle vibration. There it is demanded the quantitative analysis of spindle vibration in order to get the optimum surface roughness. This study was carried out to analyze an influence of working factors on spindle vibration by design of Experiment. The results are shown that mathematical model of regression equation for an influence of working factors on vibration acceleration of spindle in end-milling by regression analysis is presented.

It necessarily follows that wear particles are generated through a friction and wear in a mechanical moving system. The wear particles are relative to the failure and the life of machine elements directly. To analyze the wear particle, its shape characteristics were calculated quantitative values such as diameter, roundness and fractal parameters by digital image processing. In this study, the histograms of shape parameters of wear particles were used for the purpose of analyzing the distribution of wear particles in various conditions. We consider that the histogram of shape parameter can be effectively represented to study a wear mechanism.

The surface modification of automobile parts is of great technologicalimportance for the improvement of corrosion resistance, wear resistance, fatigue strength and so on. Recently, research on the development of the technology of surface modification substituting 6-balance chrome process has progressively been achieved in automobile parts. Although the innovation technology for the improve- ment of the corrosion-resisting and wear resistant properties through post oxidation after nitrocarburising process had attracted a great attention. For this, anodically potentiodynamic polarisation testing was carried out to corrosion resistance and friction and wear experiment according to applied load and sliding distance was carried out to evaluate the wear resistance of machine structural steel with nitrocarburising and non-nitrocarburising SM45C. The presumed wear volume was calculated with the image processing for evaluation of wear resistance of two materials. The results show that the nitrocarburising had a distinguished corrosion resistance and wear resistance than non-nitrocarburising.

사인(私人)이 적법절차에 따르지 아니하고 수집한 증거의 증거능력

형사소송법 제308조의 2는 “적법절차에 따르지 아니하고 수집한 증거는 증거로 할 수 없다”고 규정하고 있으나, 동 규정을 사인에 대하여도 적용할 수 있을 것인가에 대하여는 많은 논란이 있다. 위법수집증거에 대하여 증거능력을 배제하는 것은 적법절차에 따르지 아니하고 수집한 증거는 타인의 인권을 침해할 염려가 있기 때문이다. 따라서 위법하게 수집한 증거에 대하여 증거능력을 배제함으로써 증거를 수집한 자가 의도한, 사실에 대한 증명을 하지 못하도록 함으로써 수집자에 대한 징벌적 효과를 얻고, 또 장래에 그러한 행위를 하고자 하는 사람들에 대하여도 그러한 행위를 하지 못하도록 하는 일반예방적 효과를 거두어 증거수집의 대상이 되는 사람의 인권을 보호하고자 하는 것이라고 할 수 있다. 따라서 위법수집의 주체가 수사기관이 아니라 사인이라 하더라도 고소인이나 피고인과 같이 사건과 직접 관련이 있는 “관련자”라면, 그들에 대하여도 이러한 징벌적 효과와 일반예방적 효과를 얻을 수 있을 것이므로, 그들이 적법절차를 지키지 아니하고 수집한 증거에 대하여는 증거능력을 배제하여야 할 것이다. 다만 그러한 “관련자”의 행위라 하더라도 증거로 인정되지 않는 경우는 적법절차에 따르지 아니한 경우만을 의미하기 때문에, 헌법이나 형사소송법에 절차규정 자체가 존재하지 아니하는 경우에는, 단지 형법이나 기타 실체법을 위반하여 증거를 수집하였다고 하여 적법절차에 따르지 아니하고 수집한 증거라고 할 수 없다고 생각된다. 따라서 이러한 증거에 대하여 적법절차에 따르지 아니한 증거로 보아 증거능력을 배제할 수는 없다고 할 것이다. 한편, 피고인이 고문이나 폭행, 협박 등에 의하여 자백한 경우에는 형사소송법 제309조가 증거능력을 배제하고 있고, 그 고문이나 폭행, 협박행위를 한 주체에 대하여 제한을 두고 있지 아니하므로 사인에 대하여도 동 규정을 적용하여 사인이 피고인을 상대로 고문이나 폭행 협박행위에 의하여 자백을 받은 경우 증거능력이 없다고 하여야 할 것이다. 본 논문에서는 이러한 주장을 주요 쟁점으로 하여 그 논거에 대하여 설명한다. Article 308-2 of the Criminal Procedure Law states that “Any evidence obtained in violation of the due process shall not be admissible,” but there are arguments disputing if this regulation can take the same effect under the case of a private person. Admissibility of illegally acquired evidences are excluded because such evidences have possibility of infringing human rights of other people. Therefore, by excluding admissibility of illegally acquired evidence, collector of the evidence undergoes punitive effect through not being able to legitimately present a fact in a manner that the collector has originally intended, and the exclusion can also protect human rights of subjects who may be targeted by an act illegal evidence collecting act in the future, which leads to achieving general deterrence effect. Same effect will be achieved for plaintiff, defendant or anyone who is considered related to them, so their collected evidence obtained violating the due process shell be excluded from trial. However, because the exclusion are limited when the related private person’s evidence under their violation of the due process, if Constitution Law or Criminal Procedure Law do not explicitly state a due process, evidence cannot be excluded for its violation of the due process mainly because collecting act of the evidence violates Criminal Law or other substantive law. Therefore, (collector of the evidence) will claim that the evidence cannot be excluded for the collector’s violating the due process. On the other hand, when defendant was forcefully confessed because the person had experienced torture, violence, or a threat, Article 309 of Criminal Procedure Law excludes admissibility of a confession, but without limiting the subject who committed the torture, violence or a threat. So if the same rule should be applied, and thus the confession collected by a private person through torture, violence or a threat must also be treated not admissible. This paper will explain about the argument that grounds to such disputes.

이야기학의 정립을 위하여

박흥식(Park, Heung-Sik) 인문콘텐츠학회 2013 인문콘텐츠 Vol.0 No.28

이 글은 우선 서양의 대표적인 서사 작품들에서 반복되는 모티브와 캐릭터를 통해 이야기라는 것은 지속적으로 축적된다는 것을, 즉 이야기가 역사를 지니고 있다는 것을 밝히고 있다. 이어서 아직 학문으로서 아직 정립되지 않고 있는 문화콘텐츠학을 넓은 의미의 이야기의 학으로 보고 그 역사적 맥락을 살피고 있다. 그렇게 보면 문화콘텐츠학은 시학, 문예학, 서사학을 잇는 이야기의 학으로서 역사가 가장 오래된 학문이 되는 것이다. 게다가 매체까지 끌어들이면 동시에 가장 새로운 학문이 될 수 있다. 그러나 그러기 위해서는 논란이 지속되고 있는 문화콘텐츠학이라는 명칭을 버리고 서사매체학이라는 명칭을 택해 학문의 정의를 분명히 해야 함을 주장하고 있다. First of all, this paper will argue that stories have continuously accumulated through repetitive motives and characters in exemplary narratives of the Western world, and therefore that stories have their own history. Then, it will define the cultural contents studies, which have yet to be defined as an academic discipline, as the studies of stories in a broader sense and will analyze their historical contexts. The cultural contents studies, if defined as the studies of stories, can become one of the oldest disciplines in history, since they follow the traditions of poetics, the science of literature and narratology. Furthermore, they can also become one of the newest disciplines if they include the media as part of their studies. In order to do so, however, scholars in this field need to clarify the very definition of the cultural contents studies. This paper will propose that they change the name of the field from the cultural contents studies, over which controversy has continued to rage, into the studies of narratology and the media.

Benthic environments and composition of macrobenthic fauna around the marine fish culture cages were studied to clarify the effect of fish farming near Tongyong from August, 1995 to February, 1996. Sediment grain size and bottom dissolved oxygen under the fish cages were similar to that of a control site, but organic content was higher under the cages. Fewer species were found under the fish cages than under the control site, but conspicuously higher density was obtained under cages. Capitella capitata, Nebalia bipes were dominant infauna, and Asterina pectinifera and Asterias amurensis were dominant epifauna under the fish cage whereas Lumbrineris longifolia and Amphioplus sp. dominated in the control site. Diversity index showed seasonal variation under the fish cages, but showed little variation at the control site. The benthic fauna under the fish cages showed different community structures from the control site. As results, the fish culture cages affected the benthic environment and the community structure of benthic fauna by input of the organic content and biological effects such as dead shells.
