디지털 이미지와 흔적

김양호(Kim, Yang Ho) 한국디지털디자인협의회 2014 디지털디자인학연구 Vol.14 No.1

우리의 흔적은 디지털 환경에서 진보된 매체 기술에 힘입어 다양한 형식으로 복제되고 전파되고 있다. 본 연구는 디지털 이미지의 성격이 ‘흔적’과 어떻게 결합할 수 있는가를 살피고, 이미지 정보 구조 안에서 ‘흔적’의 위치를 탐색하여 빅데이터 환경에서 활용되는 이미지 전략을 어떻게 읽어야 하는가를 밝히는 것이 목적이다. 데리다는 ‘차연’의 개념으로 서구 철학의 로고스 중심주의를 해체하면서 흔적을 부재가 현존하는 개념으로 읽어내고 흔적을 모든 차이에 앞서는 차이로 규정하였다. 데리다에 의거하면 흔적 자체가 의미 일반의 절대적 근원이기 때문에 디지털이미지를 흔적으로 분석하는 것은 빅데이터 시대의 이미지 분석틀로 가치가 있다. 디지털이미지 이전의 전통적인 이미지들은 흔적을 공간성과 시간성을 변용하여 기호지시, 배치서사, 도상축약, 기술적 변형, 관념추상, 공간통합, 함축소거 등의 역할로 사용해 왔다. 이후 디지털 시대의 이미지는 이전 매체를 재매개하면서 새로운 형식을 재혼합하여 중층성, 혼종성, 가상성, 환영성, 조작가능성, 관계지향, 변형가능성 속에 흔적을 삽입한다. 빅데이터의 주된 대상인 SNS에 활용되는 디지털 이미지들의 성격을 규명하기 위한 방법으로 표상 재현과 맥락 인식으로 구분하였다. 재현체계와 인식체계로 분류하여 바라본 SNS 이미지 속의 흔적은 무형의 의미, 변형된 자국, 표식의 중첩, 사이의 증감, 숨겨진 비축과 대치라는 특성을 추론하게 한다. 유령처럼 우리 주위를 서성이는 흔적은 부재하는 현존으로 의미가 비어있는 기호이기 때문에 그 속에서 어떠한 의미를 찾아내는 것은 어려운 일이다. 다만 경계가 해체된 시대에 살아가면서 흔적을 연구하는 것은 망각의 권리가 해체되는 이 시대에서 비어있는 기호의 장소를 확인하고 다루는 방법을 찾아 낼 수 있는 열쇠가 될 것이다. Our traces are copied and distributed in the digital environment by being empowered by progressed media technologies. This study aims to find how the characteristics of digital image is combined with ‘trace’ and how to read the image strategy that searches the position of ‘trace’ in the image information structure and utilizes in the big data environment. Derrida reads ‘trace’ as the concept of existence of absence and defines ‘trace’ as the difference before all other differences while conducting deconstruct of the logocentrism of the Western philosophy with he concept of ‘Differance’. However, according to Derrida, the trace is in fact the absolute origin of sense in general so that analyzing the digital image with trace is worthwhile as an image analytic frame in the big data era. Traditional images before digital images have transformed and used the spatiality and temporality of trace for the roles of sign reference, placed narration, technical transformation, conceptual abstraction, spacial integration and connotative elimination. Images of the later digital era insert “trace” into the multi-characteristic, the hybridity, the virtuality, the illusion, the manipulation possibility, the relation orientation and the transformation possibility. To define characteristics of digital images utilized for SNS, a major target of the big data, the classification is conducted as the representation and the contextual recognition. Traces in SNS images viewed as classified as the representation and the recognition systems allow the inference characteristics such as the unformed meaning, the transformed mark, the overlapped sign, the intermediate increase or decrease and the hidden reserve and replacement. Traces wonder around us as ghosts. However, “trace” is a sign lacked of meaning as an existence of absence so that finding certain meaning in the sign is a difficult task. However, conducting researches on trace while living in the era when the boundaries are deconstructed will be a key to find methods to verify and handle the place of empty sign in this era when the right to oblivion is deconstructed.

Optimal conditions for the rapid diagnosis of Helicobacter pνlori were determined. Bacterial strains were isolated from biopsy where the u1cer was observed with endoscope. Morphological and cultural properties of the isolates were determined. Efficiency and srnsitivity of several diagnostic tests were compared. U1cer tissues as well as pure cultures of H. pνlori showed positive reaction within 5 min in urease test broth or semi-solid agar containing 10% urea and 0.1% phenol red. Urease test was highly reproducible and sensitive. Urease A gene extracted from pure culture and tissue was amplified by nested PCR using HEPY 1/2 and HEPY3 / 4 primers. Electrophoresis of PCR product confirmed that DNAs extracted from tissues and isolates which show positive reaction in urease test contain Urease A gene. Among several diagnostic methods used in general, urease test was recommended as a convenient, cheap and easy method.

This study was undertaken to detennine molecular types and genetic diversity of Helicobacter pylori isolate obtained from v따ious gastroduodenal diseases. Antral biopsies were taken for culture from 90 patients with chronic gasσitis, gasσic ulcer and duodenal ulcer at the time of endoscopy. H. pylori was identified by typical gram stain morphological and biochemical tests. UreA of the candidates were Amplified using PCR, and 30 strains were identified as H. pylori from 90 specimens. RAPD fmgerprinting was performed by 3 primers (OPA-ll, 5’-CAATCGCCGT -3 ’ OPA-18, 5’-AGGTGACCGT -3 ’ OPA-19, 5’-CAAACGTCGG-3’Operon Technologies, At1anta, GA). Relationship of the strains shown by DNA band pattem was analyzed numerically and the result were expressed as phensgram. All isolates were divided into five molecular types (1-V) at similarity (S) value of 0.4; 11 strains (36.6%), 6 strains (20.0%), 5 strains (16.7%), 5 strains (16.7%) and 3 strains (10.0%) belonged to type 11, 1, 111, V and IV, respectively. The mean S values of all isolates, type 1, 11, 111, IV and V were 0.62, 0.60, 0.66, 0.58 and 0.55, respectively. H. pylori isolates had high level of genetic diversity. The RAPD molecular types of H. pylori were not disease-specific since the types were diverse in the is이ates from various gastroduodenal diseases.

This purpose of this study was to examine their job satisfaction according to role stress, self-efficacy and working condition perceived by long-term Caregivers. The data were obtained via a questionnaires completed by 256 long-term Caregivers. The results were summarized as follows: First, As a result of analyzing the job of the research subjects, their working days were mostly ``less than 15~20 days`` with 65.6%, and their care rating was primarily a ``3 rating``, with 93.3%. As for their main jobs, most of them were engaged in ``the support of ordinary living``, with 40.4%. Concerning the active period of caregivers, they were active mostly for ``6 months~less than 1 year``, with 59.4%. Regarding their monthly pay, they received ``1.3-1.5 million won, in most cases, with 58.6%. Second, Role Stress was 3.48 points, which was shown to be higher than 3 points, which is a median. Meanwhile, self-efficacy was 2.92 pointsand job satisfaction was 2.40 points, both of which were lower than the median value of 3 points. Third, These results suggest that the statistically significant factors that affect on thier job satisfaction are role Stress (β=-.45, p<.001), self-efficacy (β=.26, p<.001), educational level (β=-.19, p<.01).

이 글은 文藝作品을 創作하려는 사람들에게 어떤 실효성 있는 構成 方法을 제시하려는 모색에서 출발한다. 構成 方法을 硏究해 보기 위해서는 잘 알려진 작품을 선정하여 모티프를 抽出해 보고, 작품 전체의 구성을 把握해 본다. 특히 각각의 모티프들이 기능하는 역할과 작품 전체에서 ‘葛藤’이나 혹은 ‘反轉’ 등의 구조 관련성 여부 등을 파악할 필요성이 있다. 기본 모티프를 나름대로 變形시켜 봄으로써 자신이 쓰고자 하는 소재를 그 기본 모티프에 適用하여 써보는 것이 구성 방법의 실제를 익히는 방법이 된다. 이런 과정을 통하여 기본 모티프를 사용한 다양한 구성 방법을 살펴볼 수 있다. 또한 모티프의 配列構造, 그리고 伏線의 적절한 장치 등이 작품에 蓋然性과 必然性을 만들어 주는 과정을 살펴보고, 그에 따라 주제 전달의 효과가 어떻게 달라지는지를 살펴보고자 한다. This paper is a sketch to be based in my own experience, which may perhaps be a effective method to construct a plot. And this paper was written to give a training method for someone to create a work. 1. A man (or woman) who wants to create literary works firstly collects a work that is his (her) most favorite or a work that has a strong influence on himself. And he (she) tries to abstract the work into some motifs. 2. Thereafter he (she) must try to grasp a correlation of those motifs, to analyze a role and a function of each motif, and to comprehend a framework of the work as a whole. 3. Basic motifs of the work were abstracted successfully, he (she) tries to modify them by various ways and to construct a new plot that is another arrangement of basic motifs. This process which has been proposed above, the method which is to modify arrangement of basic motifs, is only one of many training methods to create literary works. What must become a hard core in studying by many effective training methods is to develop an appreciative eye. That eye must be able to see the power of plot and advance hints and to grasp many multiplicate points which give the work probability and necessity.

The Electric charging system for automobile has been experimented because the generator in the system is driven by automobile engine which runs at various speed. From the experiment it is found that the charging system has overcharging problem to battery.<br/> <br/> Therefore protection device to overcharging and overvoltage is proposed in this paper. The overcharging device is divided into main charging part and assistant charging part. Main charging part is operated when battery voltage is bellow its setting value. Assistant charging part charges to the battery when the main part is not operated. The charging current value of the assistant part is near 15[%] of standard charging current in battery. The overvoltage protection action stops assistant charging together with main charging when generator output voltage exceeds its setting value.<br/> As a result of experiment, it is proven that the device has good charging performance and brings out lifetime extension of battery together with avoiding unnecessary power consumption due to overcharging.<br/> <br/>
