도로살얼음은 겨울철 급격한 기온 변화에 따라 도로 표면에 발생하는 도로 결빙 현상이다. 이러한 도로살얼음은 차량 통행에 위협이 되며 사고 발생위험을 증가시킨다. 기존에는 노면 온도가 2 ℃ 이하일 경우 주로 제설제를 살포하였으나, 제설제는 도로의 노후화를 촉진시킨다. 따라서 본 연구는 Multi-Walled Carbon Nanotube (MWCNT)가 혼입된 발열체를 활용하여 문제를 해결하고자 하며, 발열체의 크기에 따른 발열 효율을 분석하고자 한다. 발열체는 크기가 50 × 50 × 50 mm3인 큐브형과 100 × 300 × 60 mm3인 큐보이드형으로 구분하였다. 매개변수는 발열체의 크기, 양생일, 공급 전압으로 선정하였다. 큐브형의 최대 발열량은 75.7 ℃이고 큐보이드형은 큐브형의 78%까지 최대 발열량이 발생하였다. 열화상 이미지를 분석한 결과, 큐보이드형은 큐브형보다 열 분산성이 더 우수함을 확인하였다. 따라서 큐보이드형의 발열 효율은 우수한 것으로 분석되며, 큐보이드형 발열체는 도로살얼음으로 인한 피해를 감소시키는데 효과적일 것으로 판단된다. Black ice is a road-freezing phenomenon that occurs on the surfaces of roads and is caused by sub-zero temperatures. Black ice is dangerous to vehicular traffic because it is difficult for a driver to detect its presence on roads. Further, it causes vehicles to lose traction on roads, thus causing accidents. Therefore, this study aims to solve this problem by utilizing a heating module with multi-walled carbon nanotubes (MWCNTs) and analyzing the heating efficiency according to the size effect of the heating module. The heating modules were divided into cubes (50 × 50 × 50 mm3) and cuboids (100 × 300 × 60 mm3). The parameters considered were the size of the heating module, number of curing days, and supply voltage. The maximum temperature change of the cubes was 75.7 ℃, and the maximum temperature change of the cuboids was 78% of the cube. The thermal images demonstrated that the cuboids exhibited better thermal dispersibility than that exhibited by the cubes. Therefore, the heating efficiency of the cuboids was inferred to be excellent. Thus, the cuboid heating module can be used to reduce the risk of accidents occurring caused by black ice.

검안을 통해 본 여성과 사회

박소현 ( Sohyeon Park ) 한국고문서학회 2017 古文書硏究 Vol.50 No.-

본고에서는 현존하는 19세기 말 檢案 중 여성들의 일상적인 수다가 두 여인의 사망사건으로 비화된 이른바 `淮陽郡 長陽面 검안`을 통해서 당시 평민 여성들의 삶을 살펴보았다. 江原道 淮陽郡 長陽面 上新院里日耕洞이라는 외딴 산골에서 발생한 이 사건은 여인네들이 디딜방아로 쌀을 찧는 자리에서 퍼진 음행의 추문이 그 발단이 된다. 이로 인한 시비에 휘말려 임신한 文召史가 구타당한 날 밤에 숨졌고, 이에 대한 보복으로 문조이의 남편과 아들, 시동생이 문조이를 구타한 朴召史를 때려죽인다. 추문이 살인으로 비화되는 이사건을 통해서 일반적으로 사료에 잘 드러나지 않는 평민 여성들의 일상적 삶, 특히 향촌 내에서의 사회생활을 엿볼 수 있다. 따라서 회양군 장양면 사건은 여성사적 관점에서 주목할 만한데, 특히 추문에 대한 평민여성들의 반응을 통해서 유교 이데올로기에 의거한 여성성의 사회적 통제와 감시가 양반층뿐만 아니라 평민층에서도 상당한 정도로 이루어졌음을 살펴볼 수 있다. 한편 회양군 장양면 사건은 문조이의 사망원인이 구타치사인지, 아니면 음독자살인지를 규명하는 문제가 쟁점이 되어 初檢과 覆檢, 1, 2, 3차에 이르는 査案에 이르기까지 5차에 걸쳐서 사건 조사가 상당히 복잡하게 진행된다. 결국 사건의 진실은 명백하게 밝혀지지 않았음에도 불구하고, 조사 과정에서 검시 결과의 조작과 위증 및 자백의 강요 등이 있었을 가능성이 짙다. 따라서 본고에서는 검안이라는 보고서 양식 아래 은폐된 진실을 밝혀내기 위해서 檢査官 뿐만 아니라 원고와 피고, 증인 등이 활용한 수사학이나 전략에 대한 심층 분석을 시도했다. The main focus in this article lies in the analysis of an inquest record or koman from the late nineteenth century. The so-called “Case of Changyang Village, Hoeyang County 淮陽郡 長陽面 檢案” reveals the nineteenth-century commoner women`s village life that has not been found in any other historical materials. In this case, two neighboring women`s deaths were caused by a slanderous rumor on adultery. The story that Kim Choi 金召史 committed adultery with a rich elite man living in the same village was told while neighbor women pounding rice in Mun Choi`s 文召史 house. Kim Choi`s mother Pak Choi 朴召史 who thought Mun Choi made up the vicious story about her daughter Kim Choi quarreled with Mun Choi and finally hit her. At night Mun Choi who was pregnant suddenly died after suffering from severe pains. Mun Choi`s husband who believed Pak Choi caused Mun Choi`s death went to Pak Choi`s house and bit her to death along with his eleven-year-old son and younger brother. A slanderous rumor caused two neighbor women`s deaths. This case seems to interest us from the perspective of women`s history in that it sheds light on nineteenth-century commoner women and their village life. In particular, the commoner women`s reactions to slanders of their sexual integrity show how prevalent the social control and discipline of female sexuality based on the Confucian ideology was in society regardless of social status. The investigations of this case were conducted five times in order to determine whether Mun Choi`s death was caused by beating or poisoning. Mun Choi`s family claimed that the autopsy report was not only fabricated under the order of the district magistrate but also torture was used to extract confessions from the defendant and witnesses. In this respect this article also attempts to analyze the rhetoric appropriated by the defendant, plaintiff, and witnesses at the law court.

Surprisingly, Chinese gong'an fiction, even though many literary scholars have simply disregarded the genre as a trivial, vulgar, unsophisticated, and culturally inferior text, has recently been rediscovered, readapted, and revived by our contemporary mass culture. What is the most remarkable here is that this old, hackneyed, and half-forgotten text - that is, gong'an fiction - makes as great an appeal to contemporary popular audiences through new mass media as it did to a wide variety of audiences in the past. How come does this unknown genre, which first emerged from the Southern Song, flourished between the late Ming and the early Qing, and afterwards all of sudden disappeared, successfully reconnect itself with contemporary mass culture? This is partly because gong'an fiction has many affinities with the modern detective story which has been one of the most popular literary genres from the nineteenth century. Most importantly, however, it is due to "cultural dualism" inherent in gong'an fiction. In fact, gong'an fiction emerged as both a popular and ideological text from inhabiting the borders between East and West, between premodern and modern, between elite and popular culture, between oral and literate culture, and between legal and literary tradition. In this article, I try to show that gong'an fiction as a popular text is not only intelligible, simplified, and stereotyped, but also culturally ambiguous, deviant, and even conflicting. In the first part, I try to find out what gong'an fiction is, more precisely, what cultural meanings gong'an fiction reproduces in relation to the contemporary popular culture. In as much as the contemporary reader such as Robert van Gulik attempts to understand gong'an fiction, within the category of the modern detective story and on the basis of its literary formula, he/she often misreads the genre as a structurally inferior text, judging it according to Western norms and subjugating it to Western concerns. In this article, I try to show that gong'an fiction must not be just taken as loosely organized, but rather as intertextual, multivocal, and polyglot. In the second part, I have argued that gong'an fiction must be understood in the broad context of popular culture in late imperial China. In fact, the linear history of gong'an fiction, from the Song oral storytelling to the Yuan zaju drama to the Ming chantefable (cihua) to the Ming-Qing gong'an story collections, does not exist. The genre did not just evolve within the realm of oral and popular culture, but rather it had developed, making various relations with different cultures, traditions, and literatures. The evolution of gong'an fiction illustrates that a popular text indeed constantly attempts to make intercommunications with different cultures. Due to this apparent feature of heteroglossia, a popular text such as gong'an fiction tends to reveal conflicting cultural meanings and repressed different voices, which are often invisible in the dominant culture. A popular text seems to espouse the dominant ideology, but eventually resists it by means of subtle evasion and perversion. Therefore, the "subculturalness" of a popular text, according to Henry Y. H. Zhao, reveals social chaos and ideological contradictions, while a culturally higher text shows a single unity in structure and ideological coherence. Similarly, cultural ambiguities in gong'an fiction, I suggest as a conclusion, should not be considered as cultural limitations, but as "multiple possibilities for open cultural communications."

Non-Local Means을 이용한 회전 변조 시준기 영상화 알고리즘 개선

박소현(Sohyeon Park),이계민(Gyemin Lee) 대한전자공학회 2018 전자공학회논문지 Vol.55 No.11

방사선 안전 분야에서 방사선원을 영상화 하는 문제는 정확하고 신속한 대처를 위해 필수적이다. 특히, 방사선원의 위치를 시각화 하는 방법 중 하나인 회전 변조 시준기는 구조가 간단하고 효과적이다. 그러나 선원이 차폐되어 있거나 장애물에 막혀 있을 경우, 검출되는 광자의 수가 적기 때문에 선원이 없는 곳을 선원이라고 잘못 판단하는 아티팩트가 발생하는 문제점이 있다. 이를 해결하기 위해 본 논문에서는 분산 안정화 변환과 NLM을 이용한 새로운 영상화 알고리즘을 제안한다. 실험을 통해 기존의 MLEM 기반의 영상화 알고리즘과 비교하여 영상화 결과가 개선됨을 시각적, 정량적으로 검증하고, 잡음제거를 위한 다른 방법들에 비해 제안한 방법이 보다 효과적임을 보인다. Rotating Modulation Collimators(RMC) is a remote imaging technique for visualizing orphan radiation sources. However, a reconstructed image generates artifacts, when the counts of detected photons are small. As radiation sources are often blocked or shielded in a number of practical applications, the false estimates may lead to misinterpretation and misjudgement. To solve this problem, we propose a new RMC image reconstruction algorithm using variance stabilization transform and non-local means method.

법률과 사실, 그리고 서사 ―법문학비평의 관점에서 본 전근대 동아시아의 범죄소설

박소현 ( Park Sohyeon ) 한국중국어문학회 2019 中國文學 Vol.98 No.-

법과 문학의 학제적 상호영향은 법의 권위주의를 타파하고 인간성을 회복하려는 노력의 일환으로 최근에 와서 활발해졌으며, 이러한 경향을 반영한 법문학비평은 법과 문학의 관계에 대한 새로운 관점과 담론을 제공하고 있다. 특히, ‘문학으로서의 법률’ 담론은 문학의 역할을 법의 실천적 영역으로 확대시켰다는 점에서 주목할 만하며, 이 중에서도 법에 대한 서사적 비평 혹은 ‘서사로서의 법률’ 담론은 법적 스토리텔링을 통해서 기존의 제도적 권위에 도전하고 사회적 형평성을 회복하고자 한다는 점에서 그 실천적 의미를 높이 평가할 만하다. 본고에서는 명청대 중국의 공안소설과 조선 후기 송사소설 등 전근대 동아시아의 범죄소설 장르가 법과 서사의 밀접한 연관성을 인정하는 문화적 맥락 속에서 발전한 사실에 주목하여 이 장르를 법문학비평의 관점에서 분석하고자 시도했다. 정·리·법의 섬세한 균형을 유지하는 것을 이상으로 삼았던 유교적 사법전통에서는 법적 스토리텔링의 역할은 억압되기는커녕 전통적으로 중시되었다. 본고에서는 또한 법적 스토리텔링의 한 이상적 사례로서 19세기에 창작된 우화적 송사소설인 《와사옥안》을 분석했다. 《와사옥안》은 법적 스토리텔링의 이상적 사례를 보여주는 이야기로 읽힐 수 있으며, 이런 점에서 최근 법적 스토리텔링의 분석에 주목하는 현대 법문화와 전근대 사법전통의 연결고리로도 해석될 수 있을 것이다. Recently, the interdisciplinary interaction between law and literature has tended to appear more active in an attempt to subvert the authoritarian rule of law and restore the humanity of law. The recent movement of literary criticisms of law has provided new perspectives and theoretical approaches. The “law as literature” perspective in this movement seems to draw our particular attention in that it enlarges the role of literature far beyond the literary realm. More importantly, the narrative criticism of law or “law as narrative” perspective takes activist positions by challenging the institutional authority and restoring social equity through legal storytelling or the use of narratives. This article attempts to interpret the genre of crime fiction of premodern East Asia from the perspective of literary criticisms of law. In fact, this genre, including Chinese court case (gong’an) fiction and Korean court case (songsa) fiction, was developed in the cultural contexts, in which the close interrelationship between law and narrative was well acknowledged. Indeed, the role of legal storytelling was considered significant in managing the subtle balance of sentiment·principle·law in the Confucian legal tradition. In this article, a nineteenth-century Korean court case story, A Criminal Case Record of Frog and Snake, is also examined as a prominent literary example revealing how the techniques of legal storytelling reflect the idea of law and justice in the traditional legal system.

동아시아 범죄소설의 사회사 - 명청시기 공안소설(公案小說)과 조선후기 송사소설(訟事小說)의 비교를 중심으로 -

박소현 ( Park Sohyeon ) 명청사학회 2016 명청사연구 Vol.0 No.46

It seems simply unnoticed that the genre of crime fiction enjoyed a wide readership in East Asia long before Western detective fiction gained a sweeping popularity in the nineteenth-century commercial book market. As far as the genre of crime fiction of premodern East Asia is concerned, most widely circulated was Chinese gong'an 公案 fiction, which was produced in commercial printing form during the late Ming period, and afterwards transmitted to Korea and Japan. It seems remarkable that Chinese gong'an fiction was introduced to European audiences as “Chinese detective fiction” by European sinologists in the late nineteenth century. Yet, as a matter of fact, it was nothing but a mediocre popular fiction whose unchanging narrative patterns had been repeatedly reproduced for centuries. Hence, one of the most common attempts in the study of gong'an fiction is to compare it with Western detective fiction or to examine it within the methodological framework of Western narrative theories. This kind of approach, however, tended to neglect the fact that gong'an fiction was developed as part of legal culture under the precondition of its inseparable link with contemporary legal culture, which consequently led to the misconception of gong'an fiction. This article suggests that we should reread gong'an fiction in the very sociocultural context in which the text was produced and consumed. From this point of view, crime fiction may be read as a critical source of Chinese legal history or history of Chinese legal culture, which reveals the hidden truth - for instance, the gap between official representation and actual practice in Chinese law, as contended by Philip C. C. Huang - that the legal code or official legal literature simply ignored. In this respect, a comparative study of Chinese gong'an fiction and late Choson court case (songsa 訟事) fiction might contribute itself to constructing a comparative history of East Asian legal culture as well. In particular, this kind of popular texts may represent the people's point of view of legal rules and their “legal consciousness,” which was completely expunged in official legal literature. This approach will provide a rare opportunity to examine what similarities and differences were made between Ming-Qing legal culture and the Choson counterpart, and furthermore whether or not “arbitrary rule by law” prevailed in premodern East Asian society.
