This research comprises a theoretical investigation of the bundle twists created by the bundle thickness distribution while a bundle rotates by frictional force. The torque from the thickness differentials generates the twists of interest (i.e., the resulting rotation bundle differentials found in the friction area). Therefore, a theoretical model describing the dynamics of the twists per length was derived by applying continuous torque. The temporal bundle thickness is also considered. Using the model, the temporal profiles and spatial distributions of the torque twists are characterized. Under an arbitrarily chosen condition that allows simple interpretation of the torque twist characteristics, the governing equation system consisting of the model for the temporal distributions of the bundle radius on the friction drum surface and the model for the dynamic torque twists is solved, and the generation mechanisms of the torque twists are characterized. Results show that the torque twists propagate along the bundle axis in the form of a moving wave during the short time when the bundle first passes through the friction zone. After the bundle reaches a steady state, the torque twists increase very fast and then slow down as the bundle is moved by the take-up operation. Thus, the central area around the bundle axis becomes highly twisted by the superposition of the torque twists. This is because the input fleece fibers at the center accumulate for a longer distance than for the area near the bundle surface. However, at the exit of the friction area, the number of torque twists is almost zero because there is no accumulation distance for the torque twists to occur. This indicates that the torque twists are distributed with respect to the radial direction. This arc of torque-twist distribution can be described by a reciprocal relationship with respect to the radial position of the bundle cross-section.

The behavioral characteristics of sliver linear density under roller drafting operation were investigated in this study. A theoretical model describing the dynamic behavior of the staples flowing in a single direction was applied. While the model parameters remained constant, the process parameters including draw ratio and roller distance were varied. Simulations of the dynamic behavior of the drawn sliver linear density showed that it was dependent on the process conditions, and the effects varied depending on the staple length distribution. For uniform length staples, the linear density of the drawn sliver showed periodic changes at a steady state when the drawing roller distance was long. For the short drawing zone, the drawn sliver exhibited a constant steady state linear density. Increasing the draw ratio caused the linear density to change periodically which resulted in an increase in the CV% of the drawn sliver linear density. For length distributed staples, the linear density was sensitive to the draw ratio. At a low draw ratio, for example, DR=4, the drawing zone length did not affect the sliver linear density, and a constant linear density was observed. However, at high draw ratios, for example, DR=12, the drawing zone length affected the linear density behavior of the drawn sliver, showing periodic changes in the steady state. Thus, high draw ratios and long drawing zones caused a drastic increase in the CV% of the quasi-steady state linear density. In general, the two passes of sliver in a drawing operation with low draw ratio resulted in improved properties, that is, a more even linear density of the drawn sliver than that obtained using single drawing pass with a high level draw ratio, which drastically increased the linear density.

During friction yarn formation, fiber fleece is fed continuously into the gap between two surfaces moving at different speeds to build a bundle. This bundle is then pulled out of the gap and taken up onto a bobbin. During this process, the bundle obtains twists that are generated in two forms-one by fiber arrangement and the other by torque. Twists are generated in two zones, which are the friction zone and the take-up zone. Therefore, the total twists can be obtained by adding all twists occurring in the two zones. The presented research reports the structural characteristics of the friction yarn based on theoretical twist models. The yarn structure represented by the arrangement of the constituent fibers is analyzed by simulation of the theoretical models. Results show that the fiber arrangement twists are directionally opposite to the torque twists in the friction zone; for example, fiber arrangement twists are S-twists and torque twists are Z-twists. In the take-up zone, the twist generation occurs in the Z-direction. Thus, the total twist per length of the friction-spun yarn is uniformly distributed along the bundle radius. More specifically, the resultant overall twist is zero, theoretically.

In this inquiry, I would suggest jet ventilation system for effective elimination of welding flaw at machinery material welding shop on plant and evaluate the airstream on inner space and property of welding flaw's density through the examination. We can know outer atmosphere inflows at the speed of about 0.05m/s from western entrance in case of stopping the jet ventilation system, but airstream is accumulated on entire space. At height of worker's breathing surface(Ground Level = 1.5 m, below of GL) and welding work center, density of welding flaw on upper part(GL = 12m) is appeared 4 times higher than outer atmosphere at surplus range besides nearby of western entrance. At operation of jet ventilation system, since the smooth air current transfer at inner space and exhaust effect the wind speed is maintained at 0.932 m/s at the point of height of worker's breathing surface on inner space and it's concluded about the working conditions have been better than before operation of jet ventilation system because of that results show that inner space density of welding flaw at height of worker's breathing surface is 40.5%, and in the work shop, it is 20.3% at upper part.

This study deals with the thickness irregularity of the sliver delivered from a drawing process based on a theoretical model. The thickness variation was expressed as CV(%) of the linear density of the drawn sliver in a steady state. Under the given simulation conditions the simulation results illustrate that the sliver linear density shows two types of behavior: a constant linear density and a periodically changing linear density with traveling peaks. For uniform staple-length slivers the linear density has multi-modal fluctuations, whereas the slivers with a distributed staple length show no fluctuation in the linear density at low sliver viscosity. The irregularity of uniform staple-length slivers is higher than that of the staple length distributed one. As the sliver viscosity increases, the irregularity of the drawn slivers increases.

미국 주 형법상 자살관여행위 규제에 관한 입장과 그 시사점

임정호(Jung Ho Lim) 강원대학교 비교법학연구소 2014 江原法學 Vol.41 No.-

우리 형법의 해석상 일반적으로 적극적 안락사 내지 이른바 존엄사는 위법성이 조각되는 사유로 해석되지 않는다. 또한 자살을 원하는 자에 대한 자살관여행위 역시 형법상 자살방조죄 내지 자살교사죄로 처벌된다. 한편 우리나라 대법원은 2009년 5월 21일 회복 불가능한 말기(사망의 단계에 진입한) 환자에게 무의미한 연명치료의 중지를 허용하는 판결을 내렸다. 이 문제와 관련하여 2009년 2월 국회에 ‘존엄사법안’이 제출되었고, 최근에도 이를 다듬은 법률안이 정부 주도 하에 준비중이다. 그렇다면 이제 우리나라에서 말기 환자가 치료를 거부할 권리를 넘어서 자살권 내지 죽을 권리를 보유하는가도 논란이 될 수 있다. 미국의 경우 환자의 치료거부권 문제와 자살권에 대한 논의가 형법상 살인행위의 문제라기보다는 자살관여행위(주로 자살방조죄)의 문제로 다루어져 왔다. 미국은 우리보다 앞서 이 문제에 대하여 연방대법원의 몇 차례 판결이 있었고, 각 주에서 존엄사를 허용하거나 혹은 자살관여행위로 보아 처벌하도록 규정하는 등 연방과 주 차원에서 다각적 접근법을 보이고 있다. 본 연구는 존엄사 허용여부에 대한 판단의 뒷받침이 될 수 있는 미국의 형법상 자살관여행위에 대한 동향을 검토하여 그 시사점을 찾는 것을 목적으로 한다. 이를 위하여 치료거부권과 대비되는 자살권에 대한 검토를 바탕으로, 형법상 내심적 의사와 인과관계에 관한 판단의 개입가능성을 살펴 본 후, 각 주가 자살관여행위로서의 의사 주도 존엄사를 어떻게 형법적 규제대상으로 삼는지에 대하여 고찰하도록 한다. 다음으로 주 형법상 자살관여행위 해석에 있어서의 몇 가지 논점을 검토한 후, 미국법상 피해자의 승낙이 자살관여행위 및 살인행위에서 항변사유로 채택되지 못하는 본질적 이유를 살펴 그 시사점을 찾도록 한다. 이상의 검토를 바탕으로 미국의 주 법상 존엄사에 대한 자살관여행위로서의 형사처벌 여부는 자살권 내지 죽을 권리의 인정 여부에 의존치 않는다는 점을 인정한다. 오히려 형법상 자살관여행위에 있어서 행위자의 내심적 의사와 인과관계의 판단, 그리고 피해자의 승낙 불인정 이유와의 관련성이 중시되어야 함을 강조한다. 따라서 우리나라에서의 존엄사법 제정 여부는 자살권 인정여부라는 헌법적 문제에 치중할 사항이 아님을 확인한다. The Korean Supreme Court ordered to eliminate device for life-suspending treatment from a patient in 2009. It seems that the concept of ‘Death with Dignity’ in Korea is mingled with the concept of Withdrawal of Life-sustaining Treatment or Assisted-Suicide. Recently, Korean Government and Congress also try to make legislation for ‘Death with Dignity’ although the Right to Suicide has never been accepted. And it does not exactly square with the meaning from the general classifications on passive euthanasia which is not a crime in the current interpretation of the Korean Penal Code. On the basis of the critical mind on these problems under the Korean Penal Code, the Article here reviews how the U.S. Supreme Court has handled the possibility of accepting the Right to Suicide of terminally ill patient as a fundamental right and its own interpretation of Criminal Law basis such as criminal intent and causation. Hence, it examines the leading cases on Assisted-Suicide. Futhermore, it overviews a diversity of legislation and its interpretation on Assisted-Suicide. Moreover, this Article concludes that legislation on ‘Death with Dignity’ does not need to depend on whether the Right to Suicide should be protected as a fundamental right. Rather, it should be back to basic concept of criminal defense of the Victim’s Concent.

아동ㆍ청소년의 성보호에 관한 법률상 아동음란물 정의규정에 대한 미국법과의 비교 연구

임정호(Lim, Jung Ho) 국민대학교 법학연구소 2013 법학논총 Vol.25 No.3

사회적 가치가 전무한 아동음란물은 절대적으로 금지되어야 할 대상이다. 우리나라는 아동음란물에 관한 규제를 아동ㆍ청소년의 성보호에 관한 법률이 담당하고 있다. 동법은 아동음란물의 정의는 물론 관련 행위자들에 대한 강력한 처벌규정들을 두고 있다. 아동음란물에 대한 선도적이고 강력한 처벌을 시행하고 있는 미국의 경우 이에 대해 어떠한 표현의 자유도 인정하지 않고 절대적으로 금지하고 있다. 미국에서는 아동음란물의 제작, 유통, 그리고 소지행위에 대한 강력한 처벌을 아동의 성 착취 방지라는 입법목적을 위한 것으로 해석한다. 다만 아동연상음란물의 경우 비록 경우에 따라 아동대상 성범죄의 촉매제가 될 수도 있지만, 아동음란물로 규정해서는 안 된다는 것이 미국 연방대법원의 입장이다. 우리나라의 경우 아동음란물을 규제하는 아동ㆍ청소년의 성보호에 관한 법률이 아동의 성 보호와 건강한 양육은 물론이고 아동대상 성범죄의 방지를 그 주요 보호법익으로 규정하고 있다. 또한 현실적으로 우리나라에서 아동음란물과 아동대상 성범죄간 연관성을 부정할 수 없다는 점을 고려해야 한다. 따라서 실제 아동이 등장하지 아니하는 영상물 역시 아동음란물로 보아 동법에 의하여 처벌할 필요성도 존재한다. 다만 아동음란물의 범위를 지나치게 넓게 해석하여 사회적으로 불필요한 논란을 야기할 필요는 없다. 현재로서는 동법상 아동연상음란물의 규제를 위하여 별도의 경한 법정형을 두는 것이 가장 적절한 개선방안이다. Protecting children from the abuse of sexual predators is of utmost national importance. Traditional child pornography, which includes actual children in its production, necessarily involves the sexual abuse or exploitation of children. Clearly, advances in technology have made that task harder because current law made no distinction between materials depicting images of real children engaged in sexually explicit conduct from those depicting “virtual” children. In responding to these changes in technology, however, Congress have tried to revise the current law, ‘The Act on the Protection of Children and Juveniles from Sexual Abuse’ in order to alleviate anxiety of society. This Note will begin in Part I by providing an issue. Part Ⅱ will describe and explain the definition of child pornography with the traditional concerns associated with child pornography, its dangers, and the rationale behind its proscription. It will then briefly outline ‘the Act on the Protection of Children and Juveniles from Sexual Abuse’, the statute at issue in child pornography. Part III will examine several U.S. Supreme Court"s decision in the issue of child pornography in order to find implication to the Korean law. Part IV will analyze the public interest of ‘the Act on the Protection of Children and Juveniles from Sexual Abuse’ and conclude that the revised statutory definition of child pornography shall be again reviewed in support of research about the link between sexual abuse and child pornography.

본 연구는 전복 및 다시마 추출물 첨가 김치의 아미노산함량 및 발효특성에 관해 살펴보았다. 전복와 다시다는 추출물 형태로 첨가하였으며 젖산균, pH, 산도, 염도, 환원당, 유리당, 유기산, 유리 아미노산 및 관능평가를 실시하였다. 젖산균은 결과 초기 4.4~5.3 log CFU/g 수준이었으며 저장 7일째 6.8~7.1 log CFU/g 수준에 도달하였으며 그 이후에는 비슷한 수준을 유지하였다. 환원당과 유리당은 감소하는 경향을 보였으며 이는 젖산균 증식과 상관관계가 있는 것으로 나타났다. 유기산 중 citric acid, malic acid 및 succinic acid는 발효 동안 감소하는 경향을 나타내었으며 lactic acid와 acetci acid는 증가하였다. 아미노산 분석 결과 타우린은 전복 첨가 김치에서 가장 높은 수준을 나타내었으며 glutamic acid와 aspartic acid 함량은 다시마 첨가 김치에서 높은 수준을 보였다. 관능평가 결과 또한 다시마 첨가 김치를 가장 선호하였으며 전복 첨가 김치는 대조구와 비슷한 기호도 를 나타내었다. This study evaluated the quality characteristics of fermented abalone-kimchi or sea tangle-kimchi during 28 days of storage at 4℃. Abalone and sea tangle were added as extracts compared to a control. We analyzed lactic acid bacteria, pH, acidity, salinity, reducing sugars, free sugars, organic acids, free amino acids, and sensory characteristics. The lactic acid bacteria levels were 4.4~5.3 log CFU/g on day 0, 6.8~7.1 log CFU/g after 7 days, and continued to rise during the fermentation period. The salinity increased slightly over time. As fermentation progressed, pH and reducing sugars, free sugars, and organic acid contents decreased. Free sugars, in particular, dramatically decreased about 70% compared to the initial day. The total free amino acid content was higher in abalone-kimchi. In terms of free amino acid contents, taurine was high in abalone-kimchi, while glutamic acid and aspartic acid content was high in sea tangle-kimchi. The sensory evaluation results show that abalone-kimchi and sea tangle-kimchi had higher scores for their savory taste and overall acceptance compared to the control.

미국 해외부패방지법의 동향과 그 시사점 -반부패행위를 중심으로-

임정호 ( Jung Ho Lim ) 연세대학교 법학연구원 2012 法學硏究 Vol.22 No.2

The Foreign Corrupt Practices Act of 1977, as amended, 15 U.S.C. §§78dd-1, et seq. (FCPA), was enacted for the purpose of making it unlawful for certain classes of persons and entities to make payments to foreign government officials to assist in obtaining or retaining business. The past several years have seen a dramatic increase in the enforcement of the FCPA. The FCPA serves to combat bribery of foreign officials. The Act is incorporated into provisions of the Securities Exchange Act of 1934. The FCPA has two main provisions: the anti-bribery provisions; and the books and records and internal control provisions. The anti-bribery provisions are organized according to the category of entity or person covered by the FCPA. The crux of the FCPA provides for the prosecution of those who bribe foreign officials. The anti-bribery provisions apply to issuers, domestic concerns, and persons other than issuers or domestic concerns. A person other than an issuer or domestic concern can generally include foreign non-issuer companies and foreign nationals. The anti-bribery provisions will apply to such a person while he/she is in the territory of the U.S. As a general matter, the anti-bribery provisions prohibit the corrupt payment of money or anything of value to a foreign official in order to obtain or retain business. Moreover, whether one can be subject to FCPA liability for the actions of a third-party based on knowledge of the third-party``s conduct is a highly fact-dependent analysis. Obtain or retain business includes payments to a foreign official to secure a foreign government contract. However, the meaning of obtain or retain business is very uncertain. Given the Kay holding by the Fifth Circuit, it is a highly fact-dependent question whether a payment to a foreign official satisfies the obtain or retain business element outside the context of a specific foreign government contract. Furthermore, the anti-bribery provisions also contain one exception and two affirmative defenses. First, the anti-bribery provisions shall not apply to any facilitating or expediting payment to a foreign official...the purpose of which is to expedite or to secure the performance of a routine government action by a foreign official. Second, the anti-bribery provisions contain two affirmative defenses. The first is for the payment of anything of value l awful under the written laws and regulations of the foreign official``s country. However, it is impossible to find such written laws. The second is if the payment of anything of value was a reasonable and bona fide expenditure, such as travel and lodging expenses, incurred by or on behalf of a foreign official...and was directly related to (A) the promotion, demonstration, or explanation of products or services; or (B) the execution or performance of a contract with a foreign government or agency thereof. Under the FCPA, significant fines have been levied against U.S. corporations in anti-bribery provision related cases. Moreover, they are also levied against non-U.S. corporations that have agency relations with U.S. corporations. As the FTA between South Korea and the U.S. is in effect, South Korean companies are advised to review their compliance and training programs to ensure that those programs meet the standards articulated in many cases related to the FCPA. While it is almost impossible to instruct every single employee or agent, South Korean companies can take some small comfort in instituting and self-enforcing FCPA compliance and training programs.
