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.

팥배나무 아래의 재판관 - 《당음비사(棠陰比事)》를 통해 본 유교적 정의

박소현 ( Park Sohyeon ) 한국중국어문학회 2014 中國文學 Vol.80 No.-

This article aims to make a textual analysis for the Tangyin bishi (Parallel cases under the pear tree), one of the earliest Chinese legal literature or case history, from the perspective of “law and literature.” The “law and literature” movement sheds light on the close interrelationship between law and literature. In defining the term “legal literature”, there might be two different approaches: “law in literature” on the one hand and “law as literature” on the other. “Law as literature”, in particular, reflects an increasing tendency to consider law as a “text” that needs literary or cultural interpretations. This approach, however, makes us rethink the Confucian legal tradition that was founded on humanistic concerns. Although the negative understanding of the Confucian legal tradition has been prevalent in modern jurisprudence, the very tradition may not be completely disconnected from contemporary legal culture in that it endeavored to overcome the gap between the law and social reality by consistently resisting the abstract, universal, and absolute application of the law. As a matter of fact, a new tendency to highlight humanistic concerns and pay attention to hermeneutic approaches in contemporary jurisprudence has resulted from the practical intention to resolve the gap between legal rules and legal realities. The Tang`in bishi is remarkable in that it explored the interrelationship between law and literature. More often than not, the text has been misunderstood as a classical narrative lacking in narrativity or underestimated as a legal text lacking in specialist knowledge. However, the Tangyin bishi should be reconsidered as a truly unique text on the ground that it attempted at constructing the paradigm of legal rationality or public rationality with literary patterns and representing the ideal of a Confucian judge in a wide variety of case examples. This article sheds light on the representation of “Confucian justice” in the Tangyin bishi, which attempts at crossing the thin line between law and literature, rationality and emotion, and ideal and practice. The text should not be taken as a simple moral fable. For it provides various case examples for practical legal reasoning.

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.

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.

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.
