Objective : Allergic rhinitis (AR) is an allergic inflammation of the nasal airways. Socheongryong-Tang traditionally has been used in Korea for treatment of allergy diseases. In the present study, we investigated whether SCRT suppresses the progression of AR in vivo and in vitro. Method : In this study, we investigated the effect of oral administration of SCRT on the Ovalbumin(OVA)-induced allergic rhinitis mouse models. Additionally, to find a possible explanation for the anti-inflammation effects of SCRT, we evaluated the inflammatory cytokine levels in LPS-stimulated mouse inflammation cell (RAW264.7) and mouse splenocyte. Results : The finding of this study demonstrated that SCRT reduced mast cells and inflammation cells infiltration in OVA-induced nasal cavity. Additionally, SCRT inhibited the production of inflammatory cytokines in splenocyte. However SCRT don't inhibited the production of inflammatory cytokines in RAW264.7 cells. Conclusion : Taken together, our results showed that oral administration of SCRT beneficial effects in allergic rhinitis, suggesting that SCRT might be a useful candidate for the treatment of allergic rhinitis.

Center-gated 디스크에 대한 사출/압축 성형공정의 수치적 모델링-압축성을 고려한 점탄성유체 모델의 사출성형-

김일환,박성진,정성택,권태현,Kim, Ilhwan,Park, Seong-Jin,Chung, Seong-Taek,Kwon, Tai-Hun 대한기계학회 1998 大韓機械學會論文集A Vol.22 No.2

The present study attempted to numerically simulate the process in detail by developing an appropriate physical modeling and the corresponding numerical analysis for precision injection and injection/compression molding process of center-gated disk. In part I, a physical modeling and associated numerical analysis of injection molding with a compressible viscoelastic fluid model are presented. In the distribution of birefringence, the packing procedure results in the inner peaks in addition to the outer peaks near the mold surface, and values of the inner peaks increase with the packing time. Also, values of the density in the core region increase with the packing time. From the numerical results, we also found that birefringence becomes smaller as the melt temperature gets higher and that it is insignificantly affected by the flow rate and the mold temperature. As far as the density distribution is concerned, mold temperature affected the distribution of density especially near the wall. But it was not significantly affected by flow rate and melt temperature. Numerical results of birefringence coincided with experimental data qualitatively but didn't quantitatively.

WWW 대리 서버를 위한 가변 크기 개체 캐시의 대체 기법

김일환(Ilhwan Kim),염헌영(Heon Y.Yeom),이준원(Joonwon Lee) 한국정보과학회 1997 정보과학회논문지 : 시스템 및 이론 Vol.24 No.4

인터넷의 사용량은 WWW(World Wide Web)의 출현에 의해 빠른 속도로 증가하고 있다. 이에 따라 네트웍 통신량을 줄이는 방법이 요구되고 있다. 캐싱은 통신량을 줄이는 방법으로서 잘 알려져 있으며, WWW 서버, 클라이언트, 대리 서버(proxy server)에서 많이 사용되고 있다. 일반적인 캐시에서는 서로 다른 크기를 가지는 개체들이 고정된 크기의 페이지 단위로 나뉘어져 관리된다. WWW에서의 개체는 전체가 한 덩어리로 다루어지기 때문에, 캐시 대체 (replacement)에 있어 기존의 고정 캐싱과는 다른 방법이 요구 된다. 이 논문에서는 몇 가지의 가변 크기 개체 캐시의 대체 알고리듬들을 제안하고, 각 알고리듬의 성능 및 개선 방향을 trace-driven 모의 실험을 통해 검토한다. The advent of the Web service brought out the explosive growth of Internet, which necessitates a scheme to reduce the network traffic. Caching is a popular method in reducing such traffic, and it is widely used in many Webservers, clients, and proxy servers. Since an object of Web service is accessed as a whole, the cache replacement scheme should be different from others that usually treat a piece of an object as a unit of caching. In this paper, we propose several replacement strategies for variable size object cache. The performances and possible improvements of the proposed schemes are studied by trace-driven simulations.

김일환(Ilhwan Kim),이수범(Soobum Lee),허승진(Seung-Jin Heo),정재일(Jay Il Jeong) 한국자동차공학회 2010 한국자동차공학회 학술대회 및 전시회 Vol.2010 No.11

A sunroof system, is opened and closed part of roof panel, has many benefits that are able to control ventilation and brightness. Particularly, wide openness of panorama sunroof gives drivers and passengers to feel openness. Kinds of conventional sunroof system are pop-up, out-sliding and in-sliding types. Recently, customers’ needs about wide openness of sunroof system have been increased. Redesign of BIW is inevitable for installation of sunroof system on BIW. In the past, it was possible to reduce to install the sunroof without the redesigning BIW. However, it needs to redesign BIW for wide sunroof for wide openness currently. Therefore structures of sunroof system must redeem reducing strength and stiffness by structural alterations of BIW. In this paper, methods of analysis and test are proposed for evaluation of sunroof system’s performance. Through these methods, structural performances are evaluated about in-sliding and panorama type sunroof system.

시계열 공기어 네트워크 분석을 이용한 유의어 분석

김일환 ( Kim Ilhwan ) 민족어문학회 2017 어문논집 Vol.- No.80

이 연구는 외국어가 한국어에 유입되어 정착되어 가는 양상을 `시계열 공기어(共起語, coocurrence word) 네트워크`라는 분석 방법을 활용하여 밝혀보는 데 있다. 유사한 의미나 개념을 가지고 있는 고유어가 존재함에도 불구하고 그 고유어에 대응되는 차용어가 유입되면서 고유어와 차용어는 새로운 유의 관계를 형성하게 된다. 이 연구에서는 이와 같이 형성된 유의(類意) 관계에 속하는 고유어와 차용어를 분석의 대상으로 삼았다. 즉 유의(類意) 관계에 속하는 고유어와 차용어를 분석의 대상으로 삼고 이들이 지난 70여 년 동안의 신문 빅데이터에서 어떻게 사용상의 변화를 경험하였는지 공기어 네트워크를 활용하여 분석하였다. 그 결과 `천막-텐트, 사치-럭셔리, 주방장-셰프, 포도주-와인` 등의 유의어에서 영어 외래어는 고유어에 비해 고급스럽거나 긍정적인 뉘앙스를 가진다는 점을 명시적으로 규명하였으며, 이는 향후 다른 유의어들의 변화 추이를 밝히는 데에도 활용될 수 있음을 보였다. The purpose of this study is to reveal the way in which foreign languages are introduced into Korean by utilizing the `co-occurrence word network` analysis method. Despite the existence of words with similar meanings and concepts in the native language, loanwords corresponding to the native words are introduced, resulting in new and significant relationships between both words. This study focuses on analyzing native words and their corresponding loanwords of similar meaning. Utilizing the co-occurrence network, big data collected from newspapers from the past 70 years was analyzed in order to reveal how the usage of these words have changed. Results indicate that for words such as tent, wine, chef, and luxury, the English loanwords carry a more high-class or positive nuance than the native words. Furthermore, the results also reveal the potential of utilizing the co-occurrence word network to further reveal developments of change in other pairs of synonyms.

개인정보의 보호와 이용법제의 분석을 위한 헌법상 고찰

김일환(ILHWAN KIM) 한국헌법학회 2011 憲法學硏究 Vol.17 No.2

헌법상 개인정보자기결정권은 원칙적으로 자기의 개인정보를 공개하고 이용하는 것에 관하여 스스로 결정할 개개인의 권리를 뜻한다. 그러나 이러한 개인정보자기결정권은 자기의 정보에 관한 절대적인 지배권을 개인에게 부여하지는 않는다. 개인정보자기결정권과 개인정보의 공개와 이용에 관한 권리들 간에 갈등이 있음은 물론 부인될 수는 없다. 그럼에도 불구하고 가능한 한 양자 모두 그 작용을 발현하고 한 권리가 다른 권리를 통하여 절대적으로 차단되지 않을 것이 요구된다. 따라서 이 양자 간에 존재하는 이러한 긴장관계를 조정하는 것은 우선적으로 입법자의 과제이다. 그리고 입법자가 이러한 과제를 충실히 수행한 경우에 개개 경우에 구체적으로 개인정보보호가 우선되는지 아니면 개인정보의 공개나 이용이 중요시되는지를 판단해야만 하는 것이다. 헌법상 개인정보의 보호와 이용에 관한 다양한 기본권들이 있는 바, 이에 대한 고찰은 매우 중요하다. 왜냐하면 이러한 분석과 연구가 선행되어야만 관련 법제의 정비방향과 내용들이 체계적이고 구체적으로 제시될 수 있기 때문이다. 특히 2004년 이후 개인정보보호법 제정논의가 지루하게 이루어지는 과정 속에서 공공부문과 민간부문에서 개인정보보호 및 이용과 관련하여 일관된 원칙과 기준없이 많은 법률들이 만들어졌다. 이제부터 새로 제정된 개인정보보호법에 맞추어 기존의 관련 법률들을 재검토해야 한다. In principle, the constitutional right to self decision of personal information is the right to decide to open and use personal information for themselves. However this right to self decision of personal information doesn’t vest absolute control respecting own information to each individual. We can not deny, of course, that there exist conflicts between the right of decision for personal information and the right of opening and using personal information to the public. Nonetheless, both rights need to function desirably as far as possible. And it is required that one right should not disturb the other right. Therefore, it is a lawmaker’s tasks to arbitrate a dispute between the two. When lawmaker faithfully carries out one’s such duties, we have to judge concretely whether the protection of personal information should take precedence over opening and utilization of personal information to the public or not. Constitutionally, there are diverse rights concerning the protection and utilization of personal information. It is very important to study about these protection and utilization. The importance of preceding this study in advance lies in the fact that the improvement direction and contents of related legal system can be concretely and systematically suggested afterward. Later, particularly since 2004, many regulations were enacted without consistent principle and standard concerning the protection and utilization of personal information in the field of public and private sectors during the tedious process of enacting the personal information law. From now on, several established laws should be reconsidered according to the new personal information protection law.

전자주민증 도입을 위한 법제정비방안에 관한 헌법상 고찰

김일환(Kim, Ilhwan) 한국헌법학회 2011 憲法學硏究 Vol.17 No.4

정보사회에서 전자주민증의 도입여부는 주민등록법에 대한 헌법적 판단으로까지 거슬러 올라가야만 한다. 따라서 이미 추진되고 있는 전자주민증의 도입은 전자주민증 자체를 어떻게 만들 것인지, 그 안에 무엇을 담을 것인 지라는 논의만으로 해결될 수 있는 것이 아니다. 게다가 외부로 드러나지 않는다 하여 전자주민증에 담길 정보 자체의 위헌여부 시비가 사라지는 것도 아니다. 그렇다면 전자주민증, 개인식별번호의 필요성이나 그 도입여부 등은 행정의 효율성이나 편리성차원이 아니라 ‘헌법’차원에서 과연 허용되는지를 ‘규범적’으로 살펴보아야만 한다. 농경사회에서 산업사회를 거쳐 정보사회에 이르기까지 국가는 국민의 신원을 확인하고 거주관계를 파악할 권한과 의무가 있다. 하지만 현행 주민등록법이 많은 문제점을 가지고 있는 상황 속에서 단순히 전자주민증에 대하여 적극적으로 대처한다고 해서 해결될 일은 아니라고 판단된다. 오히려 적극적으로 국가에서 이러한 문제를 풀어가기 위한 장단기 법제정비방안을 제시하고 그에 따라서 지금 해결해야 할 문제와 시간을 두고 해결해야 할 문제에 대한 고민이 필요하다. 결국이에 대한 헌법적 판단은 해당 분야의 문제로만 한정되지 않고, ‘정보사회’, ‘첨단과학기술사회’에서 국가의 역할과 기능 및 이러한 사회에서 국민의 기본권이 어떻게 보호되어야만 하는지에 관한 논의를 시작하게 하는 아주 중요한 문제이다. Since 2013, Korean Government has been promoted in the process of revising acts to introduce the electronic resident registration. It is a welcome measure that ministry of public administration security launched an improvement of legal system to protect personal information and to resolve problem of existing resident registration system. But it is not enough that discussing only methods and contents of e-resident registration to resolve many related problems. Because there could be still the unconstitutional possibility of the personal information contained in e-resident registration card. Then the introduction of electronic resident registration system must be checked to be constitutionally friendly now. The introducing the e-resident registration should be decided in the view of constitution especially the protection of constitutional right. In other words, considering the constitutional suitability of resident registration system is more important than examining the administrative convenience and effectiveness before introducing e-resident registration system. For this reason we need to check the e-resident registration system runs counter to the sprit of the Constitution or not in the aspect of sound social norms. In the resident registration system, people need to report part of their personal information. But, in identification system, all people must get issuing certificates contains the unique number of many, many people. So that the resident registration system should be treated differently from the identification system. In reference to resident registration, it is needed to look over several foreign countries system like the Federal Republic of Germany in the aspect of comparative law. Some countries have only a system and related laws of resident registration without identification systems. Some countries like Germany have the resident registration system and also identification system. In Germany, types and ranges of personal information required can be varied according to the legislative purpose of related laws. Thus on the whole, it is necessary to review systematically the current resident registration law. In other words, under the current resident registration law, they should collect and handle only personal information for surveying population movement like the residents’ relationship on neighborhood boundary and so on. In this connection, there must be a full understanding of reasons that resident registration system and the identification system should be treated differently. And, at the same time, there must be the consideration of redesign of legal system in social security area with taking effectual measures upon each legislative aim. In this context, the introduction of e-resident registration should be introduced in stages.

공기어 네트워크와 사회 계층에 대한 관심의 트렌드

김일환(Kim ILHWAN),정유진(Chung EUGENE) 한국사전학회 2011 한국사전학 Vol.- No.18

This paper intends to comprehensively describe and explore three target words and their associated words extracted from a Korean newspaper collection, the Trends 21 Corpus (Kim, et al., 2010). The target words refer to social class such as pwuyuchung ('the rich class'), cwungsanchung ('the middle class'), and pinkonchung ('the poor class'). The associated words co-occur with the target words in the same paragraph. Concerns surrounding each social class can be explored via the words used in the news articles issued from the year 2000 to the year 2009. Based on our work, the co-occurring words represent the characteristics and class distinctions of each social class. For example, both pwuyuchung and cwungsanchung co-occur with seykum ('tax'), apatu ('apartment'), janye ('sons and daughters'), and so on. However, kokup ('high quality'), myengpwum ('luxury goods'), baykhwajem ('department store') and twenty other words only co-occur with pwuyuchung. We present a statistical analysis of the texts to illustrate changes in the social class. In order to reach our goal, we adopt a network analysis in order to understand cultural differences in each class as well as the social change within social class, as captured in the words. We have used t-score to estimate associations between words and employed Pajek (Nooy, Mrvar, & Vladimir, 2005) to visualize the relationship between a target word and its co-occurring words.

현행 개인정보보호법체계상 감독기구 법제정비방안에 관한 연구

김일환(Kim, Ilhwan) 미국헌법학회 2017 美國憲法硏究 Vol.28 No.2

By establishing personal information protection act, the perpetual dangers of personal information leaks will be decreased. So that it is expected that it could contribute to the steady development of personal information industry. Meanwhile, the status and the role of personal information protection commission amounted to nothing at all in the process of the personal information. Ultimately, personal information protection commission prescribed on a alternative lacks theses things like the independence and powers of personal information protection organization compared to international standards and earlier discussion at level in the meantime. I think that the commission according to the alternative in this situation is not only disorganized but also inconsistent. so that this commission will not do an adequate role as the independent organization. Therefore I think that the alternative of personal information protection act demands systematization, disambiguation and rearrangement.
