화학공장에서 발생하는 사고의 발생원인은 다양하지만, 전 세계적으로 발생되는 산업재해의 96%는 근로 자의 불안전행동에 의해 발생된다. 국제노동기구(International Labour Organization, ILO)에서는 근로자의 불안 전행동에 의한 사고의 위험성을 경고하기 위하여 산업현장에서 다발적으로 발생하는 근로자의 불안전 행동을 20개의 요소로 구분하여 발표한 바 있으며, 산업재해 예방을 위해서는 근로자의 불안전행동을 제어하여야 한다고 강조하고 있다. 본 연구에서는 근로자의 불안전행동을 관리할 수 있는 방법을 알아보기 위하여 국내 사업장의 사고조사 이력 정보를 토대로 현장에서 다발적으로 발생하는 주요 불안전행동 유형을 분석 하였다. 주요 불안전행동 분석 결과를 기반으로 Swiss Cheese Model을 이용하여 불안전 행동을 유발하는 근본원인을 분석하였으며, 각 근본원인별 관리방법을 제안하였다. The causes of accidents occurring in chemical plants vary, but 96% of industrial accidents occur- ring worldwide are caused by workers' unsafe behavior. The International Labour Organization (ILO) has an- nounced 20 elements of workers' anxiety-warning behaviors that occur on multiple occasions at industrial sites in order to warn them of the risk of accidents caused by workers' anxiety-driven behavior, and to prevent in- dustrial accidents, workers' anxiety-driven behavior should be controlled under stress In this study, major types of unsafe behavior were analyzed on the basis of information on the accident investigation history of do- mestic workspaces in order to find out how workers can manage their unsafe behavior. Based on the results of the analysis of the major anxiety war behavior, the root cause of causing anxiety war behavior was analyzed us- ing the Swiss Cheese Model, and each root cause management method was proposed.

CFD 모델링을 이용한 화학공장의 안전거리 산정 방법론에 관한 연구

백주홍 ( Ju Hong Baek ),이향직 ( Hyang Jig Lee ),장창봉 ( Chang Bong Jang ) 한국안전학회(구 한국산업안전학회) 2016 한국안전학회지 Vol.31 No.3

As the simple empirical and phenomenological model applied to the analysis of leakage and explosion of chemical substances does not regard numerous variables, such as positional density of installations and equipment, turbulence, atmospheric conditions, obstacles, and wind effects, there is a significant gap between actual accident consequence and computation. Therefore, the risk management of a chemical plant based on such a computation surely has low reliability. Since a process plant is required to have outcomes more similar to the actual outcomes to secure highly reliable safety, this study was designed to apply the CFD (computational fluid dynamics) simulation technique to analyze a virtual prediction under numerous variables of leakages and explosions very similarly to reality, in order to review the computation technique of the practical safety distance at a process plant.

CFD 시뮬레이션을 이용한 제한된 공간에서의 수소, LNG, LPG 폭발특성 비교

백주홍(Ju-Hong Baek),이향직(Hyang-Jig Lee),장창봉(Chang Bong Jang) 한국가스학회 2016 한국가스학회지 Vol.20 No.3

화석연료의 의존도를 줄이고자 대체에너지 연구가 활발하게 이루어지고 있는 현재, 산업에서 가장 많이 사용하고 있는 대체에너지 중 하나가 수소이다. 수소의 수요는 매년 꾸준히 증가하고 있으며, 수소의 생산 및 이송을 위한 설비도 늘어나고 있는 실정이다. 이에 따른 수소설비에서 중대사고가 발생할 확률 또한 증가할 것으로 예상된다. 또한 산업현장에서 가장 사고를 많이 초래하는 물질은 LPG 61%, 수소 12%, LNG 10%로 세 가지 가연성가스의 사고 빈도는 높은 축에 속한다. 따라서 산업용으로 많이 사용되며 사고다발성 가연성 가스인 수소, LNG, LPG가 제한된 공간에서 폭발했을 때의 폭발위험성에 대하여 CFD 시뮬레이션을 이용하여 계산을 하였고, 그 결과들을 기반으로 비교분석하여, 제한된 공간에서의 각 가스별 폭발에 대한 위험성을 검토하였다. The demand for hydrogen is steadily increasing every year, and the facilities to produce and transfer hydrogen are being increased as well. Therefore, the possibility of a critical accident at hydrogen is expected to increase. Furthermore, the materials most likely to cause accidents at industrial sites are LPG 61%, hydrogen 12%, and LNG 10%, and the frequency of accidents due to these three combustible gases is relatively high. Thus, a CFD simulation was used to compute the explosion risk of danger-frequent combustible gases - hydrogen, LNG, and LPG - within a limited space, and the outcomes were compared and analyzed to review the risk of explosion of each gase within a limited space.

백주홍(Baek, Ju Hong),김보연(Kim, Boyeun) 한국디지털디자인협의회 2013 디지털디자인학연구 Vol.13 No.4

디자인 사고가 사회적 이슈가 된 이후로, 창의적인 인재를 요구하는 흐름이 생겨났고 창의성 교육에 대한 수요가 늘어났다. 이에 따라 국내에서도 창의력 향상을 위한 어린이 디자인 캠프나 디자인체험교육 등 워크숍 형태의 프로그램들이 많이 생겨났다. 하지만 그 내용을 살펴보면 디자인 사고를 통해 문제해결의 프로세스를 가르치는 워크숍은 많지 않았다. 디자인 사고에 대한 이해와 다양한 방법론을 살펴보고 창의력에 대한 이론을 바탕으로 국내외 사례를 조사하였다. 또한 실제로 어린이를 대상으로 창의적 워크숍을 기획 및 진행하여 결과를 분석하고 향후 활용방향을 모색해 보았다. 워크숍은 참가자의 구성과 프로세스의 방법에 따라 결과물이 달라졌으나 워크숍의 궁극적인 목적에는 부합하였다. 워크숍 종료 후 진행한 설문조사의 결과, 디자인 사고에 대한 이해가 증가하였고, 흥미도 역시 높게 나왔다. 이는 어린이 창의적 워크숍의 가능성을 말해준다. The Design thinking became social issues and creative education demand has risen sharply. There are number of creative workshop programs has been increased such as children"s design workshop and design experience education for children. Eventhough there are many of creative workshops for children, only few programs instructed problem solving strategy using the design thinking process. Therefore understanding the design thinking process, design methods, and creativity are key factors to developing previous creative workshop program. The finding will be used tool for design a new children"s creative workshop and analyzed results for direction of utilizing. The end result of workshop is different with personal organization and process, but accord with the final aim of workshop. In the result of servey, children understand design thinking more deeply and have an interest in workshop. This result suggests that creative workshop has a possibility.

Favorable Versus Unfavorable Synoptic Backgrounds for Indirect Precipitation Events Ahead of Tropical Cyclones Approaching the Korean Peninsula: A Comparison of Two Cases

백은혁,김주홍,국종성,임규호 한국기상학회 2013 Asia-Pacific Journal of Atmospheric Sciences Vol.49 No.3

This study identifies favorable synoptic backgrounds for indirect precipitation events over the Korean Peninsula that occur well in advance of tropical cyclone (TC) landfall. Two TCs, i.e.,Rammasun (2002) and Maemi (2003) that made landfall and produced heavy rainfall over the Peninsula are compared. Although both had a remarkably similar accumulated rainfall pattern over the peninsula, the temporal evolutions of hourly rainfall were different. Only Maemi had an indirect precipitation event in conjunction with a midlatitude trough to its north. The confluent flows at middle-toupper levels were strengthened due to the increased pressure gradient between the midlatitude trough and the subtropical high, and the warm advection by the confluent flows also became stronger near the confluent zone. By contrast, Rammasun encountered the subtropical ridge while moving northward, which results in slow recurvature and reduction of the thermal gradient over the peninsula. The highly baroclinic synoptic backgrounds in the Maemi case lead to the midlevel frontogenesis. Budget analyses using the three-dimensional frontogenesis equation revealed that the horizontal deformation forcing had a primary role in generating the front. The front was associated with a thermally direct circulation that contributed to strong ascent and indirect precipitation over the peninsula well in advance of the landfall of Maemi. Moreover, the indirect precipitation could intensify due to the abundant low-level moisture supply to the frontal zone by the southerly wind on the east side of the TC.

Even if the purpose and functions of electronic Bills of Lading are the same as those of traditional B/L, the characteristics of media used for electronic Bills of Lading are different from those of traditional B/L in nature to have different technical operative features and legal effects. In this research, what the cause of the crisis of bills of lading is, what kinds of methods are introduced in electronic Bills of Lading to have the same functions as traditional B/L, and how the relationship between electronic Bills of Lading and related laws is formed were surveyed from commercial and legal aspects. To secure the function as document of title and the transferability of electronic Bills of Lading, various electronic Bills of Lading were studied and the Bolero system, succeeded in its commercialization mainly in Europe, was introduced. The Bolero electronic Bills of Lading operated on the Bolero system realized the essential operative functions of traditional B/L. Some of these are the receipt document of products, the evidence of the transportation contract of products and securities enabling the transfer of ownership etc. In addition, traditional transaction processes can be realized more rapidly without damaging the legal effectiveness in electronic Transactions. However, the Bolero is far from perfect. There are several problems in its practical usage. These problems can be reviewed from legal and practical aspects, respectively.

A Critical Role of Extreme Atlantic Windstorms in Arctic Warming

홍자영,김백민,백은혁,김주홍,Xiangdong Zhang,김성중 한국기상학회 2020 Asia-Pacific Journal of Atmospheric Sciences Vol.56 No.1

Here we show that Atlantic windstorms of extreme category in northern winter tend to follow a well-defined route toward the Atlantic sector of Arctic, and that heat and moisture transported by these extreme storms significantly warm the Arctic. A positive North Atlantic Oscillation (NAO) condition and the associated intensified upper-level Atlantic jet provide favorable conditions for those extreme storm developments through enhanced vertical wind shear. These extreme windstorms lead to two discernible impacts on the Arctic: 1) enhanced poleward energy transport by moisture intrusion to the Arctic, which accompanies increased longwave downward radiation and 2) the occurrence of blocking-like patterns after the storm break-up. During these periods, significant Arctic warming was observed of a 10-fold increase versus normal and weak storms. The poleward deflections of extreme storms, and the Arctic warming driven by such storms, are well simulated in numerical experiments with oceanatmosphere coupled models.

하이퍼매개 이론적 특성을 바탕으로 한 디지털 패션매거진 디자인에 관한 연구

강누리(Kang, Nuri),백주홍(Baek, Juhong),김보연(Kim, Boyeun) 한국디지털디자인협의회 2014 디지털디자인학연구 Vol.14 No.1

매체환경이 빠르게 변화하면서 정보의 성격이 단순히 수동적인 정보의 전달이 아닌 경험으로 확장되어 패션매거진의 콘텐츠를 제공하는데 강점이 많아졌다. 하지만 현재 판매되고 있는 디지털 패션매거진은 정체성이 불분명하고 디자인적 측면에서 매체의 특성을 잘 활용하지 못하고 있는 실정이다. 이에 본 연구에서는 재매개 이론을 적용하여 표지, 목차, 광고, 정보, 인터뷰, 화보에 대해서 하이퍼매개적 디자인요소를 정리하고 사용자들에게 어떠한 경험을 제공하는지 알기 위해 심층 인터뷰를 진행하였다. 하이퍼매개적 디자인 요소를 구조적, 시지각적 디자인요소로 나누고 디지털매거진에 사용된 효과를 조사하였다. 구조적 디자인요소에는 기본페이지, 스크롤다운, 상·하이동, 좌·우 이동, 외부 하이퍼링크, 내부 하이퍼링크가 있고, 시지각적 디자인요소에는 텍스트 애니메이션,텍스트 팝업, 텍스트 스크롤, 이미지 스크롤, 중첩이미지, 자동플레이 영상이 있다. 이러한 디자인요소를 바탕으로 정보기반과 화보기반의 디지털 패션매거진에 대하여 어떠한 요소가 사용되었는지 정리하였다. 정리된 내용을 바탕으로 제이콥 닐슨의 공식을 적용하여 사용자 심층인터뷰를 진행함으로써 두 매거진을 비교 평가하였다. 비교평가 결과에서 매체의 특성에 맞는 하이퍼매개적 디자인요소들이 사용되었을 때 사용자들의 반응이 긍정적으로 나타났다. 디지털 패션 매거진은 사용성과 목적성을 만족시켜야 하며, 매체가 갖는 특성에 맞게 콘텐츠를 개발해야 될 필요가 있다. Fashion magazines’ contents have evolved with rapid progress in media environment which enabled the information to become an experience. However, digital fashion magazines on sale at this moment have vague identity and fail to utilize the medium’s characteristics in design perspective. Therefore, this study applied re-mediation theory to analyze hyper-mediated design factors of cover, content, advertisement, information, interview, and pictorial. Then, interviews were conducted on users to examine their experiences with the digital magazine. Hyper-mediated design factors were divided into structural and visual-perceptual design factors, then surveyed their effectiveness in said digital magazines. Structural design factors include basic page, scroll down, up-down movement, left-right movement, external hyperlink, and internal hyperlink. Visual-perceptual design factors include text-animation, text pop-up, text scroll, image scroll, overlapping image, and auto-play videos. Information based and pictorial based digital fashion magazines have been analyzed and their uses of aforementioned design factors were recorded. Based on the findings, Jacob Nilson’s theory was applied to the in depth interview on users.
