소설의 재매개와 포스트휴먼의 형성-소설 ≪천룡팔부(天龍八部)≫에서 게임 ≪천룡팔부(天龍八部)3D≫까지-

최재용 ( Choi Jae-yong ) 한국중국어문학회 2017 中國文學 Vol.90 No.-

본고는 소설 《天龍八部》가 디지털 게임 《天龍八部3D》로 재매개(remediate)되는 과정을 추적하고, 그 과정 중에서 나타나는 미디어 판본의 차이를 밝힌다. 나아가 그 과정 속에서 새로운 주체, 즉 포스트휴먼이 등장하고 있다고 주장한다. This study starts with Jin Yong`s famous novel, < Demi-Gods and Semi-Devils >, or < Tianlongbabu >. But what I mainly discussed is not the novel itself, but a mobile game < Tianlongbabu3D >, which is based on the novel. I tried to find out what happened during the process of translating the novel into the game, and to explain what it means. One of my two main concept is `remediation`. When a new media emerges, people tend to think that this new media is going to completely replace the old one. But the invention of camera did not extinguish painters, and kindle did not replace paperback. In fact, picture and painting, e-book and actual book created a complex interaction, affecting each other. We call this interaction `remediation`. When a novel < Tianlongbabu > was transformed into a mobile game < Tianlongbabu3D >, this `remediation` happened. The game looks like it`s telling the same story as the novel did, but different media has different characteristic. For instance, in the game you can visit the same place as many times as you want, and beat enemies you couldn`t dream of beating in the novel. Next main concept is `posthuman`. By posthuman, I mean the change of the very concept of human being. To humanism subject, reason is very important. They have very clear `boundary`, which consists their `self`. But posthuman transcends above this boundary. They embrace `alien` things like metal arm or electric body parts, they do not exclude things that were considered to be outside of the boundary, like cyborg, robot or A.I.. I think what we see in the game < Tianlongbabu3D > is the emergence of posthuman. The playable character that the player controls is posthuman, and the player itself is also posthuman. Above the boundary of human/smartphone, the posthuman ascends. In short, through this study I found out that the remediation of novel by game produces new meanings and activities, and that the very concept of human self is shaking. Posthuman is already among us.

다중 임계치 함수의 TI 웨이브렛 잡음제거 기법

최재용,Choi, Jae-Yong 한국음향학회 2006 韓國音響學會誌 Vol.25 No.7

수중 방사소음 측정시 낮은 신호대 잡음비를 가지는 신호에 대해 유용한 신호를 얻기 위해서는 잡음제거가 이루어져야 한다. 본 논문은 잡음제거를 수행하기 위하여 Donoho 등에 의해 제안된 Translation-Invariant (TI) 웨이브렛 기반으로 다중 임계치 함수를 적용한 잡음제거 기법을 제안한다. 기존의 웨이브렛 잡음제거 기법은 특이점 부근에서 Pseudo-Gibbs 현상이 발생하는 문제점이 있다 TI 웨이브렛은 신호의 특성 위치를 변화시켜 Pseudo-Gibbs 현상을 제거한다. 그리고 배경잡음 및 외부잡음을 제거하기 위해 각 노드별 변형된 소프트 임계치를 적용한 다중 임계치 함수를 제안한다. 제안 기법의 타당성을 검토하기 위해 모의 시뮬레이션과 해상실험을 수행한 결과 신호대 잡음비가 23dB 및 18dB 이상 개선됨을 확인하였다. This paper proposes an improved do-noising method using multi-thresholding function based on translation-invariant (W) wavelet proposed by Donoho et al. for underwater radiated noise measurement. The traditional wavelet thresholding de-noising method causes Pseudo-Gibbs phenomena near singularities due to discrete wavelet transform. In order to suppress Pseudo-Gibbs Phenomena, a do-noising method combining multi-thresholding function with the translation-invariant wavelet transform is proposed in this paper. The multi-thresholding function is a modified soft-thresholding to each node according to the discriminated threshold so as to reject かon external noise and white gaussian noise. It is verified by numerical simulation. And the experimental results are confirmed through sea-trial using multi-single sensors.

This paper describes a calculation method of source level of a ship transient noise, which is one of the important elements for the ship detection. Aim of transient noise measurements is to evaluate of acoustic energy due to singular occurrence, which is therefore defined as non-periodic and short termed events like an attack periscope, a rudder and a torpedo door. In generally, in the case of randomly spaced impulse, the spectrum becomes a broadband random noise with no distinctive pattern. Therefore, frequency analysis is not particularly revealing for type of signal. In the paper, it is performed in time domain to analyze a transient noise. However, a source level of transient noise is required an investigation for multiple frequency band. So, in order to calculate a source level of transient noise, a design of exponential weighting function, convolution, band pass filtering, peak detection, root mean square, and parameter compensation are applied. The effectiveness of this calculation scheme is studied through computer simulations and a sea test. Furthermore, an application of the method is applied in a real case.

최재용,손권,도경철,Choi, Jae-Yong,Son, Kweon,Dho, Kyeong-Cheol 한국군사과학기술학회 2003 한국군사과학기술학회지 Vol.6 No.2

Underwater acoustic noise measurement is an essential element for vulnerability assessment of modern naval platforms. But during the last few decades environmental conditions have drastically changed due to the gradually increasing sea ambient noise level and decreasing submarine radiated noise level. A real-time underwater acoustic measurement system with vertical line array is designed for the quiet submarine radiated noise assessment in challenging environment. This system has a constant directivity index in measurement frequency range and accurate tracking capability for the transmission loss compensation and navigation aids inside the submarine. This system has been validated at sea and used several times for the submarine noise measurement.

최재용,손권,Choi, jae-Yong,Son, Kweon 한국음향학회 2004 韓國音響學會誌 Vol.23 No.5

본 논문에서는, 미지 위치의 원거리 능동음원을 이용하여 해저고정형 선배열 센서에 대한 3차원 배열형상추정 기법을 제안하였다. 본 연구는 센서에 도달하는 음파가 평면파라는 가정 하에 기준센서와 나머지 센서간의 음파도달 시간지연, 센서위치 및 입사각과의 선형방정식의 해를 반복적 최소자승법에 의해 구함으로서 센서위치 추정이 가능하다. 제안된 기법의 타당성을 검증하기 위해 컴퓨터 시뮬레이션과 실제 해상실험을 수행하였으며, 이론적 분석을 통하여 음원 위치 분포에 따른 성능 및 시간지연 오차에 따른 센서위치 추정 성능을 분석하였다. This paper proposes an algorithm that estimates three dimensional array shape calibration about the bottom-mounted sensor array. under the assumption that the active sources are in the far-field with unknown positions. Under some assumptions. we calculate the sensor positions via an algebraic solutions of a least squares problem that the linear equations are related to the sensor positions and directions or arrival. We give examples of algorithm performance from both computer simulations and sea test. We also illustrate the performance of sensor positions estimation as a function of time delay estimation variance and the distribution of the localizing sources.

최재용,손권,도경철,Choi, Jae-Yong,Son, Kweon,Dho, Kyeong-Cheol 한국음향학회 2000 韓國音響學會誌 Vol.19 No.5

수중음향 측정 및 수동형 탐지에서는 표적 방사음향의 방위 탐지가 매우 중요하다. 표적의 방사음향이 다수 개의 청음 센서에 수신되면서 각 센서마다 시간적으로 지연되어 도달한다. 이와 같은 시간지연을 추출함으로서 표적 방위 추출이 가능하다. 본 연구에서는 시간지연 추정을 위해 RSSL 적응필터를 이용한 새로운 RLSLTDE 알고리즘을 제안한다. RLSLTDE는 표적 방사음향에 대한 정보가 제한적이거나 추정하려는 시간지연 정보가 시변인 경우에 효율적이다. 신호대 잡음비에 따른 시뮬레이션에 결과, 기존 LMS 적응필터 알고리즘 보다 수렴특성 및 시간지연추정 속도면에서 우수하여 제안 알고리즘이 수중음향 입사방위 추정에 유용함을 확인하였다. The bearing detection of radiated target noise is very important at underwater acoustic measurement and passive detection. It differs the arrival tines of received signal at each sensor. Therefore, the bearing can be obtained from the time delay. This paper proposes a new algorithm using the RLSL adaptive filter for TDE. The proposed method is particularly attractive when there is a limitation of priori information about the received signal spectra and when the delay is subject to variation. As the simulation results, it is shown that the proposed algorithm has better convergence characteristics and TDE speed, and so that the usefulness of proposed algorithm is confirmed.

Farmers seek for high profitability by increasing the best use of land, and the selection of crops is the first and basic way to achieve their goals. When farmers select crops, the climate, price and productivity of crops are usually considered at the first stage. However, a crucial factor is to understand general characteristics of soils where the crops were grown, but many farmers are lacking in detailed knowledge about soils. The purpose of this study is to search and analyses factors based upon related soil and others in decision-making for the selection of crops. In result, the cultivated rate of the top 5 corps in the suitable areas for cultivation (SAC) is only 53 % which shows most farmers are plants their crops in unsuitable sites. To examine factors influencing on the selection of crops except for soils, surveys about their farm characteristic and Korea Soil Information System (KSIS) were conducted. The result of survey shows 20 % of farmers know KSIS. To increase that rate, there were many changes on soil's characteristic, and at the same time, climate conditions should be updated. It can be expected to increase the rate of farmers' utilization of KSIS.

Yong-Jae Kim(김용재),Jae Yong Choi(최재용),Sang Uk Son(손상욱),Ki Cheol Ahn(안기철),Hyun Joon Keum(금현준),Suk Han Lee(이석한),Do Young Byun(변도영),Han Seo Ko(고한서) 대한기계학회 2008 대한기계학회 춘추학술대회 Vol.2008 No.11

An EHD (Electro-Hydro-Dynamic) jet for electrostatic inkjet head shows advantages to print micro-size patterns using various inks because it can generate sub-micron droplets and can use highly viscous inks. Thus, many researchers in industrial fields are concerned about the EHD jet in these days. Since the basic principle of the EHD jet is to form a droplet from an apex of meniscus at the end of the nozzle, the ejection mechanism can be changed by the shape of the meniscus. The stable ejection of the droplet is greatly affected by the shape of the meniscus which is also influenced by surface characteristics of the nozzle, electric potential and ink properties. Experiments have been performed using the nozzles with hydrophilic and hydrophobic coatings in this study. The hydrophobic nozzle forms the stable droplets in wider range of the electric potential than the hydrophilic nozzle does.

목적 : 언어 발달 문제를 주소로 내원하여 단순언어장애로 진단받은 아동의 임상적 경과를 관찰하고자 이 연구를 시행하였다. 방법 : 대동 병원 소아청소년과 외래에 2007년 7월부터 2008년 6월까지 말과 언어 지연을 주소로 내원하여 언어 및 발달 검사를 받았던 아동 125명 중 단순언어장애로 진단받은 아동 51명에 대한 치료 및 임상 경과를 조사하였다. 자료에 대한 설문조사는 전화 및 외래 방문 면담으로 시행하였다. 결과 : 단순언어장애로 진단 받은 51명의 아동 중 혼합 수용-표현언어장애는 39명(76.5%), 표현언어장애는 12명 (23.5%) 이었다. 추적관찰이 불가능한 10명과 치료를 하지 않았거나, 치료 도중 탈락한 아동 11명을 제외한 30명 중 혼합 수용-표현언어장애 아동은 23명(76.7%), 표현언어장애 아동은 7명 (23.3%)이었다. 이들 아동 30명 중에서 전체적인 치료기간은 혼합 수용-표현언어장애 아동은 18.1±10.0개월, 표현언어장애 아동은 8.6±3.6개월로 통계적으로 유의한 차이가 있었다(P=0.014). 언어치료를 받은 혼합수용-표현언어장애 아동 23명 중 13명(57%)과 표현언어장애 아동 7명중 모두(100%)에서 치료가 종결되었다. 그러나 언어치료가 종결된 아동에서 언어치료가 종결되기 까지의 기간은 혼합 수용-표현언어장애 아동에서 12.2±8.7개월, 표현언어장애 아동 군에서 8.6±3.6개월로 표현언어장애 아동에서 치료기간이 짧아 보였으나 통계적으로 유의한 차이는 없었다(P=0.287). 결론 : 이전의 논문들의 고찰 및 본 연구를 통하여 볼 때, 단순언어장애 아동을 외래에서 진료 시 혼합 수용-표현언어장애 아동과 표현언어장애 아동으로 구분하여 치료하는 것은 단순언어장애 아동의 치료기간 뿐만 아니라 언어치료에 대한 경과나 예후를 예측하는데 도움이 될 것으로 생각된다. 앞으로 소아청소년과 차원에서의 단순 언어장애 아동에 대한 조기평가와 효과적인 치료방법에 대한 관심이 절실히 요구된다. Purpose: The purpose of this study was to evaluate the clinical characteristics of children who had been diagnosed as specific language impairment as outpatients. Methods: One hundred twenty-five speech- or language-delayed patients were enrolled in Dae-Dong Hospital from July 2007 to June 2008. Fifty-one of 125 children were diagnosed as specific language impairment in whom clinical factors such as duration of therapy and progress after therapy were evaluated. Data were obtained from telephone or direct personal interviews. Results: Among 51 children diagnosed as specific language impairment, 39 (76.5%) had mixed receptive-expressive-type language disorder and 12 (23.5%) had expressive-type language disorder. Thirty children in total were studied as ten children were unavailable for follow-up and eleven dropped out during treatment. The final 30 children consisting of 23 with mixed receptive-expressive type language disorder and seven children with expressive-type language disorder were treated after diagnosis. Total average treatment duration of children with mixed receptive-expressive-type and expressive-type language disorder were 18.1 months and 8.6 months, respectively, a statistically significant difference (P=0.014). Thirteen (57%) of 23 children with mixed receptive-expressive-type language disorder and all (100%) seven children with expressive-type language disorder completed speech therapy with an average treatment duration of 12.2 and 8.6 months, respectively; however. this difference was not statistically significant(P=0.287). Conclusion: Classifying patients with specific language impairments into mixed receptive-expressive-type and expressive-type language disorder in an outpatient department can be useful for predicting duration of and prognostic effects of language therapy. as our study and other previous articles have shown. More attention is needed from pediatricians to ensure the effective assessment and management of specific language impairment.
