From Economic point of view, today is tendency to remodel or destruct old buildings consisted of more five stories with the rapid development of blasting technique. It is of great important to make up for the insufficient empirical knowledge in blasting demolition through priori method such as computer simulation. In recent years, the collapse behavior of reinforced concrete (RC) structure buildings by means of blasting demolition technique has been studied mainly using numerical analysis method. The non-linear collapse behavior of RC structure buildings can be expressed using three dimensional analysis of large displacement collapse behavior. Numerical simulation programs have contributed to a better understanding of large displacement collapse behavior during explosive demolition, but much remains to be done and limitations to be solved. Field scale demolition of RC structure buildings are expensive and very time consuming. For these reason, it is necessary to employ small-scaled RC structure buildings to explosive demolition. The purpose of this study is to estimating collapse behavior of prototype RC structure buildings based on the experimental demolition of small-scaled RC structure buildings. The experimental demolitions in this study employ the similitude law using the density of prototype structure materials to analyze the collapse behavior of the prototype RC structure buildings. The maximum size of coarse aggregate in the small-scaled RC structure buildings was used to estimate the scale factor representing the length of cross section of prototype concrete members. The scale factor for determining the steel bar used in the small-scaled RC structure buildings was estimated by using the representative diameter of prototype steel bars. Small-scaled RC structure members are designed by Concrete Standard Specification as well as Design Standard of Concrete Structure. Also, it is possible to replace epoxy resin with fixation as well as connection of members by structure manufacture. When small-scaled RC structure buildings were collapsed by blasting, felling and toppling method were selected. As results of analyzing vertical, horizontal direction displacement and angle of rotation, redistribute load time of abutment load was respectively different and the collapse velocity was able to be controlled by blasting time. The five-story buildings constructed with the small-scaled RC structure buildings were demolished by means of drilling and blast technique. To observe the collapse behavior of the RC structure buildings during demolition, the digital video camera images obtained from each test were analyzed and discussed. Finally, based on the results obtained from the observations study, a method for estimating dynamic response of the prototype RC structure buildings is proposed and also discussed.

The domestic dam are that it is vulnerable to the water leak by deterioration of central clay and various reasons. This study attempts to identify the stability of central clay which forms body of most dam. Clay soil exists in the center of dam body in order to prevent water, the condition of this part becomes the core of stability of whole dam body and the fact whether it leaks or not. This study conducted dipole-dipole array resistivity survey to determine the stability of central clay & base in the dam body. Where, Heterogeneous part is that it can't perform the function of central clay preventing water, and it could become the cause of water leak and problem of stability of dam body as the central clay is transform or washed away by constant pressure as regards upstream pondage of dam body. This transformed central clay & base shows more changes in the resistivity value than stable part. The purpose of this study is to identify the part which causes the problem of stability of dam body through resistivity prospecting in the Jang-Sung Gun water dams.

경찰과 민간경호·경비의 상호협력에 관한 연구

유지완 전주대학교 행정대학원 2012 국내석사

범죄예방 및 질서유지를 담당하고 있는 경찰은 국가공권력의 최 일선에서 국민의 생명과 재산을 보호하고, 급변하는 사회 및 국민의식 변화에 따른 새로운 치안수요에 능동적으로 대처해야하는 과중한 업무를 책임지고 있다. 그러나 국민의 안전에 대한 욕구의 증가에 경찰력은 인력 및 예산 부족 등으로 한계를 보이고 있다. 이러한 경찰력의 한계는 민간경비가 치안의 공백을 보완할 수 있는 방법이라고 할 수 있다. 우리나라 민간경비는 현재까지(2011년 12월 31일 경찰청 자료) 경비회사 3,651개와 그 산하에 146,286명의 경비원 종사하고 있으며, 공경비와 함께 치안서비스의 공급주체로서 국민의 재산과 안전을 보호하고 범죄를 예방하는 역할을 성실히 수행하고 있다. 그러나 민간경비가 급속히 성장하고 있다는 점과 경찰력이 민생치안에 있어서 한계에 달했다는 점에서 볼 때 민간경비와 경찰의 상호협력이 그 어느 때보다도 절실하다고 할 수 있다. 또한 대부분의 방범활동이 경찰조직 위주로 국가정책이 확립되고 추진되어 왔기 때문에 민간경비와 경찰의 협조체제구축에 있어서는 별다른 진전을 가져오지 못하였다. 따라서 경찰과 민간경비의 효율적인 범죄예방활동을 위한 상호협조체제를 구축하는 데 있어 문제점 및 개선방향들을 분석하여 다음과 결론에 도달하였다. 경찰과 민간경비의 상호협력체제의 문제점으로는 업무상의 상호간 이해 부족, 경찰과 민간경비의 상호 괴리감, 상호지원체계의 미비, 경찰과 민간경비간의 정책의 빈곤, 상호협력 방범체제 구축을 위한 정보교환 미비, 민간경비의 제도적인 문제, 경찰의 민간경비 담당기구의 문제 등을 지적되었다. 이러한 문제점을 해결하기 위한 상호협력방안으로 전담책임자제도와 합동순찰제도, 민간경비 전문 인력의 양성과 경찰의 민간경비 전담기구 운영, 청원경찰법과 경비업법의 단일화 방안, 경보 대응 체제 구축 등을 제안하였다. 또한 현재 다양하고 치명적인 범죄가 사회적으로 대두되는 시점에서 신변에 위협을 느끼는 사람들의 생명과 재산을 경찰관들만의 힘으로 보호하기에는 경찰력에 한계가 있다. 이런 문제점을 보완하고, 국민들의 양질의 치안서비스를 제공하기 위해서는 경찰과 민간경비가 상호협력적인 관계의 유지가 무엇보다 중요하다고 할 수 있겠다. 따라서 범죄예방은 단순히 경찰만의 문제가 아니라 국민 전체의 문제로 받아들이며, 경찰과 유기적인 관계에 있는 민간경비에 대한 국민의 인식의 전환과, 이를 활성화시키는 국가 정책을 통해 경찰과 민간경비의 상호관계를 효율적으로 전개해 나가야 할 것이다. Police managing crime prevention and order maintenance protects the public`s life and property at the front of the government authority and responsibles for actively responding to new public needs in this fast changing society and changing national consciousness. But, with the short of human resources and budget, police has failed to meet the demand. In fact, security can supplement the problems in public order from the limitation of police power. Now there are 3,651 security offices and 146,286 guards in Korea (Data of Dec. 31 2011 from National Police Agency), and they have been protecting properties and safety of the public and preventing crimes as a public order service provider with police. As private security is rapidly growing and the police is facing difficulty meeting public order needs, mutual cooperation of private security and police is evermore urgent. Also, most of crime prevention is designed and performed by police, making bare improvements in mutual cooperation of private security and police. So, I analyze problems and improvement methods for establishing cooperation for effective crime prevention. The result is as follows. The problems in cooperation between police and private security are lack of understanding in task, mutual gap of them, lack of mutual support system, lack of policy of between police and private security, lack of information exchange for establishing mutual crime prevention, political problems of private security, and problems of police in charge of private security. To address these problems, I suggest exclusive charge system, joint patrol system, nurturing specialized guards of private security and running a police department in charge of private security, unification method of private police policy and security policy, and establishing warning respond system. Also, as various types of crime are appeared at this time, police faces limitation to protect life and property of the public sensing danger on their own. To supplement the problems and provide high quality public order service to the people, mutual cooperation of police and private security is the most important thing. So, crime prevention has to be perceived as a problem of the people as a whole, not just of police. The people need to change their awareness toward private security organically related with police, and with government policy activating awareness change, we should effectively develop mutual cooperation of private security and police.

카프카의 <굴>에서 나타나는 근대적 청각 경험과 영화/기계매체의 소리

유지완 연세대학교 대학원 2021 국내석사

이 논문은 카프카의 <굴>이 근대적 청각 경험과 맺고 있는 관계를 연구한다. 그리고 <굴>에서 나타나는 소음의 문제를 근대적 음향 매체의 소리, 나아가서 영화의 소리와 비교한다. 카프카의 <굴>은 안전하고 조용한 굴의 내부와 적의 위협으로부터 안전하지 않은 외부의 구분에서 시작한다. 이야기의 중반, 알 수 없는 소리가 굴 내부를 장악한다. 화자는 소리의 원인을 찾고 정체를 밝혀내기 위해 여러 가지 추측을 하고, 검사를 실행하지만 소리의 원인은 드러나지 않는다. 이 텍스트는 화자가 건설한 굴의 건축적 구조 안에서 소리의 원인을 찾기 위한 시도와 실패의 과정으로 이루어져있다. 이 과정에서 굴의 안전한 내부와 위험한 외부에 대한 위상전환이 발생한다. 이러한 전환은 굴의 건축적 구조와 연결되어 있는 굴의 청각적 상태로서의 소음, 그리고 화자의 지각과 맞물려있다. <굴>의 소리는 원인이 보이지 않고 알 수 없는 상태에서 소리가 현상하는 ‘아쿠스마티크’한 것으로 나타난다. 믈라덴 돌라는 <굴>의 소리의 이러한 특징이 근대적 음향 매체가 작동하는 방식과 같다는 점을 지적한다. 축음기, 전화와 같이 소리의 원인이 보이지 않는 상태에서 소리가 들리는 매체의 청각적 경험은 근대에 출현한 새로운 감각이었다. 이와 더불어 음향 매체는 의미화 할 수 없는 소리의 덩어리인 ‘소음’을 생산하는 것으로 나타났다. 이 논문은 <굴>의 소리가 보이지 않고, 원인을 알 수 없는 동시에 의미화 할 수 없는 것으로 근대적 음향 매체의 청각적 현상과 만나는 지점에 주목한다. <굴>은 이러한 청각적 감각 속에서 소리가 세계에 개입하는 현상을 관찰하는 하나의 실험실이다. 이 논문은 소리와 세계의 관계에 대한 <굴>의 실험을 근대적 음향 매체, 그리고 영화의 음향적 조건 속에 놓고 근대의 청각성에 다가가는 지도로 읽는다. 지도의 출발점에서 <굴>의 소리를 ‘아쿠스마티크’한 것으로 파악할 때, 그것은 영화의 아쿠스마티크 사운드가 하나의 세계를 둘러싸고 기능하는 방식과 비교할 수 있다. 미셸 시옹의 연구에서 영화의 ‘아쿠스마티크’한 소리는 스크린 내부와 외부, 그리고 디제시스 내부와 외부를 넘나들며 세계의 경계를 흐린다. 영화의 소리가 작동하는 방식에 비추어 볼 때 <굴>의 소리는 이야기 내부에서 들을 수 있지만 그 원인을 내부에서 끝내 찾을 수 없기 때문에 디제시스 안에서 살고 있는 인물이 닿을 수 없는 외부, 즉 비디제시스적인 영역에 걸쳐있는 것으로 나타난다. 이를 통해서 <굴>의 소리는 화자의 인식과 이야기의 영역 바깥을 사유하게 만드는 현상으로 존재한다. 피터 체르카스키의 파운드 푸티지 영화 <Outer space>는 이와 같은 <굴>의 구조에 대한 영화적 사례로서 영화의 서사적 이미지가 펼쳐지는 세계 바깥에서 소음이 개입하는 형상을 보여준다. <Outer space>는 공포영화, <The Entity>의 필름 복사본을 손상시켜 만들어진 효과들로 이루어져 있다. 필름에서 발생한 시청각적 노이즈로 구성된 이 영화는 매체의 소음을 전면에 드러낸다. 이 영화에서 소음은 필름의 외부적 표면과 내부에서 산출하는 이미지들을 뒤섞는다. 영화의 내부와 외부는 매체의 흔적과 과정을 노출하며 소음의 현상과 함께 중첩되어있다. 이 논문은 <굴>의 소음이 이야기 내부에서 찾을 수 없는 시공간적 평면에서 발생하여 이야기 안으로 흘러들어오고, 굴의 내부와 외부를 재구성하는 것으로 기능하는 것과 체르카스키의 영화를 비교하고 분석한다. <굴>에서 소음은 인식과 앎의 한계를 가져오는 현상으로 나타난다. 이 과정에서 <굴>의 소음은 카프카가 자신의 작품 전반에서 다루고 있는 주제, 한 개인이 그를 둘러싼 세계로부터 겪는 소외의 문제를 청각적 차원에서 드러낸다. 이러한 소외의 문제는 근대의 기술매체 앞에서 개인이 겪는 감각 체계의 변화와 연결되어 있으며, 음향 매체가 소리를 산출하고 전환하는 과정에서 발생하는 낯선 것으로서 소음을 마주하는 것에서 온다. 이와 같은 맥락에서 이 논문은 <굴>의 소음을 카프카의 시대에 등장한 음향 매체의 근대적 청각 경험과 비교하고, 그 연장선에서 영화의 소리를 다룬다. 이를 통해 매체의 소음이 디제시스/비디제시스의 경계를 가로질러 청각적 추상성의 영역으로 나아가는 형상을 발견한다. This paper focuses on Kafka's <The Burrow> and its relationship to the modern auditory experience. By examining sound featured in <The Burrow>, this study relates the issue of noise to modern acoustic technology and furthermore draws a comparsion to cinematic sound. Kafka's <The Burrow> begins with the distinction between the ‘inside’ of a safe and quiet burrow and the ‘outside,’ which is not safe from external threats. In the middle of the story, an unknown sound takes over the inside of the burrow. The narrator makes various guesses and tests to find out the cause of the sound and uncover its identity, but the cause of the sound is not revealed. This text consists of various processes of failure and attempts to find the cause of sound within the architectural structure of the burrow built by the narrator. In this process, a topological shift occurs between the safe interior of the burrow and the dangerous exterior. This transformation occurs as noise becomes an auditory state of the burrow, which is connected to its architectural structure as well as the narrator's perception. The sound described in <The Burrow> appears to be “acousmatic,” as sound occurs in a state where the cause is unknown and not visible. Mladen Dolar points out that this characteristic of the sound of <The Burrow> resembles the way modern acoustic devices function. The auditory experience of media where sound is heard in a state where the cause of sound is not visible, such as a phonograph or telephone, was a new sensation of modernity. In addition, these acoustic devices produced 'noise,' a clump of sounds that in themselves do not carry meaning. This paper focuses on the intersection where the sound described in <The Burrow> meets the auditory phenomena brought forth by modern acoustic media where the source of sound cannot — be seen and its cause, unknown and meaningless. <The Burrow> is a laboratory that observes the phenomenon of sound intervening in the world in this auditory sense. This study places <The Burrow>'s experiment at a crossroad between sound and the world heard through acoustic devices developed at the time, as well as the auditory conditions of a film—using Kafka’s text as a map to navigate towards understanding the acoustics of modernity. Characterizing the sound in <The Burrow> as “acousmatic” serves as the starting node of a map wherein one can start to draw relations to cinema, comparing how acousmatic sound in film operates in the world it surrounds. To Michel Chion, “acousmatic” sound of a film traverses in and out of the screen, furthermore the inside and outside the diegesis–blurring the boundaries of the world. Compared to the way the sound of a film functions, the sound of <The Burrow> can be heard inside the narrative, but because its cause cannot be located inside the story, it finds home in the non-diegetic “outside” –a realm that one living in the midst of the diegesis cannot reach. The sound of <The Burrow> as a phenomenon allows for critical reflection outside the narrator’s perception and the realm of the story. Peter Tscherkassky's <Outer Space> is a cinematic example analogous to the structure of <The Burrow>, as the noise in the film, too, originates from the ‘outside’-exterior to where the diegetic image of the film unfolds. As a found-footage film, <Outer Space> consists of effects created by damaging film copies of the horror movie, <The Entity>. Composed of audio-visual noise generated by celluloid film, <Outer Space> reveals the noise of filmic materiality itself. In this film, noise merges the images produced by the film's diegesis as well as its material surface. The inside and outside of the film expose traces and processes of the medium, overlapping with the phenomenon of noise. This paper analyzes the ways in which noise described in <The Burrow> functions, as sound occurs upon a spatio-temporal plane that cannot be found in the story, yet flows into the narrative, reconfiguring the interior and exterior space of the burrow and compares these characteristics — of Kafka’s text with Tscherkassky's film. In <The Burrow>, noise appears as a phenomenon that brings the limits of awareness and knowledge to surface. Through this process, the noise of <The Burrow> reveals the subject Kafka is dealing with throughout his work: the problem of alienation that an individual experiences from the world, surrounding him, expressed through an auditory dimension. The problem of alienation is connected to changes in the sensory system experienced by individuals surrounded by modern technological media, facing noises that appear as uncanny figures as machinery process and produce sound. In this sense, this paper compares the noise of <The Burrow> with the modern auditory experience of new acoustic media that appeared in Kafka's era, and extends the discourse into the sound of film. Through this comparison, noise of the medium crosses the boundary between diegesis/non-diegesis and enters into the realm of auditory abstraction.

Assessment of Blasting Efficiency through the Application of Crack-inducing holes and Pre-splitting Ji-Wan Yoo

유지완 한양대학교 대학원 2025 국내박사

This study evaluated the efficiency and applicability of a new blasting technique, Combined Blasting, developed to address the issues of blast-induced vibration and overbreak during tunnel excavation while enhancing excavation efficiency. The conventional General Blasting (Smooth Blasting) method has been associated with problems such as frequent complaints in residential and vibration-sensitive areas due to high vibration levels, and increased reinforcement costs resulting from excessive overbreak caused by rock damage. To overcome these challenges, this study proposes a blasting technique that combines crack-inducing holes and precrack holes to simultaneously achieve vibration reduction and overbreak control. This research consists of three main parts. First, a comparative analysis of the blasting mechanisms of the conventional General Blasting and the newly proposed Combined Blasting was conducted using the PFC2D numerical simulation program. The simulation results indicated that Combined Blasting achieved a 29.3–65.9% reduction in vibration across all rock types (soft rock, medium rock, and hard rock), with a more pronounced effect observed in areas closer to the blast source. Moreover, in terms of overbreak, Combined Blasting reduced overbreak by up to 54.2% and also suppressed underbreak. Second, full-scale field blasting experiments were conducted in the Samsung–Dongtan railway tunnel site located in Suseo-dong, Seoul, to verify the performance of the two techniques under actual site conditions. The results showed that Combined Blasting reduced blast-induced vibration by up to 33.5% and overbreak cross-sectional area by 20.2% compared to General Blasting. These improvements are expected to reduce complaints due to vibration and lower reinforcement costs associated with excessive overbreak. Furthermore, time-history analysis revealed that the precrack effect of Combined Blasting achieved a vibration isolation effect of approximately 33.4% in the central area and up to 44.6% in the peripheral and invert areas. This indicates that applying precrack blasting to the peripheral zones prior to main blasting can significantly attenuate vibration at tunnel excavation boundaries, thereby improving tunnel face stability and safety of adjacent structures. Third, using vibration data collected from the Sanggye–Nowon power duct construction site in Nowon-gu, Seoul, the transmission characteristics of blasting-induced vibration were quantitatively analyzed through regression analysis and frequency domain analysis. The results demonstrated that Combined Blasting exhibited improved values of blasting coefficient (K) and attenuation exponent (n) compared to the conventional method, achieving up to 46% vibration reduction under equivalent scaled distance conditions. Additionally, FFT-based frequency analysis showed that high-frequency components were rapidly attenuated with increasing distance in Combined Blasting, and dominant frequencies were concentrated below 100 Hz beyond a scaled distance of 60 m/kg1/2. In contrast, General Blasting maintained relatively higher high-frequency components. This selective attenuation of high-frequency components is interpreted as the effect of propagation through precrack surfaces and heterogeneous interfaces within the rock mass. Furthermore, under conditions satisfying vibration criteria, the permissible charge per delay for Combined Blasting was approximately 2.2 times higher than that for General Blasting, indicating superior performance in terms of excavation efficiency and construction period reduction. In conclusion, Combined Blasting is an effective technique for reducing blast-induced vibration and controlling overbreak in tunnel excavation sites located near residential areas and vibration-sensitive structures. It also exhibits excellent constructability and economic feasibility. In the future, this technology is expected to be widely applicable in tunnel blasting projects by establishing optimized design guidelines for various ground conditions.
