명품에 대한 사회학적 해석 : An analysis of consumption of luxuries

최항섭 서울대학교 사회과학연구원 2003 한국사회과학 Vol.25 No.1-2

본 연구는 한국사회에서의 과시적 문화를 설명하기 위해서 명품소비를 분석하였다. 명품은 그 교환가치에 있어서나 상징가치에 있어서나 사치스럽고 고급스럽다고 사회의 일반적 인정을 받은 재화를 말한다 이러한 명품은 과거에는 주로 상류층만이 구매하는 것으로 인식되었으나 현재 비상류층 역시 명품구매에 적극적으로 나서고 있다. 명품은 상류층이 비상류층과의 구분을 위해서 사용되는 것이 일반적이지만 비상류층 역시 상류층을 모방하기 위해서 사용하고 있기도 하다 명품이 인기가 있는 이유로는 먼저 상징적 가치가 높은 재화에 대한 소유욕구의 재생산을 들 수 있으며, 비상류층이 명품구매에 뛰어들고 있는 현상은 '일치'의 욕구라고도 볼 수 있는데, 즉 ‘남들처럼’ 소비하는 행위를 말한다 과시의 욕구는 명품구매의 대표적 원인이며, 이외에도 명품자체의 미에 만해서 사는 것도 가능하며, 자신의 가치와 명품의 가치를 일치시키려는 욕구, 손에 닿을 수 없으리라 생각했던 것를 넣었을 때의 성취 감, 고급스러움을 유포하는 한국의 미디어, 베버적 의미의 사회적 폐쇄를 위한 상류층간의 연결망 형성과 유지의 필요성등이 현재 명품의 인기의 원인으로 제시될 수 있다 이러한 명품의 인기에 대해서는 긍정적 인식과 부정적 인식이 공존한다. 긍정적 인식은 좋은 것에 대한 자연스러운 욕구라는 데 기초하며, 부정적 인식은 프로테스탄트적 비판이 주류이다. 또한 비상류층의 명품구매에 대해서는 강한 비판들이 많이 나왔는데, 분수를 모르는 행위라고 비난하였으며 이는 한국사회에서 아직 강한 집단적 동질성이 그 집단의 성원에게 요구되고 있음을 간접적으로 보여준다 This paper concentrates on the consumption of luxuries in South Korea, which is one of the aspects of conspicuous culture in Korean society. We have to note that it is not only the high class but also the middle class, and even the low class who purchase the luxuries. While one buy luxuries to distinguish himself, others buy luxuries to imitate the high class. I also examined that traditional aspect of confarmity in Korean society is one of the key words to explain the explosion of desire for luxuries. People buy luxuries since their neighborhood buy them. Luxuries are often used as an element to link people, expecially high class as they possess symbolic value. There exist positive perspective and negative perspective on purchasing act of luxuries. Although some people regard it as natural and reasonable, others critic it based on protestant ethic. In particular, purchasing act of luxuries by the low class is severely criticized.

Performed to study on effect of economic characters and quantity of Cd in silkworm body by feeding artificial diet which aded Cd per density to all age silkworms. The results were as follows: 1. Each treated parts was a little longer than control on silkworm larval duration. 2. Growing condition of 40 ppm on the 7th day after commencement incubation was uneven and found out around 80% of 1st instar-silkworm larvae which almost didn't grow at ones of 80 ppm. 3. Maximum weight of the 5th instar, pupation ratio, weight of cocoon, weight of cocoon layer and cocoon layer ratio of parts of 1,10, and 20 ppm was a lettle higher than control, but only ones of 40 ppm was lower than those. And found out it ws chronic toxicity. 4. Each treated parts on eclosion period was longer than control. Expecially non-eclosion ratio of 40 ppm was 30%. 5. The safe level density of Cd in diet was 20 ppm. 6. Toxicity will be occurred when Cd contents in is more than 5 PPM in silkworm body.

家蠶을 5齡起蠶과 熟蠶때에 腹部 第 2,4,6 神經球를 摘出하여 絹絲線發育, 吐絲量, Fibroin 含量比, 營繭形態 및 ??體色의 變化에 대해 試驗하였던 바 그 結果는 다음과 같다. 1. 絹絲線의 發育은 腹部 第 4,6 神經球 摘出보다 腹部 第 2 神經球 摘出이 더 크다. 2. 各 神經球 摘出은 絹絲線의 屈曲現像을 보였다. 3. 吐絲量은 腹部 第 4,6 神經球 摘出보다 腹部 第 2 神經球 摘出이 적었다. 4. 絹絲線의 發育정도와 吐絲量은 같은 傾向을 보였다. 5. 繭絲의 Fibroin 含量比는 腹部 第 6 神經球 影響이 腹部 第 2,4 神經球보다 큰 것 같다. 6. 神經球 摘出의 경우 表面의 營繭形態는 薄皮營繭이었고 腹部 第 4 神經球 摘出의 裏面의 營繭形態는 대부분 ??體半露出繭을 나타내었다. 7. 腹部 第 2,4,6 神經球는 化?? 및 ??體色의 變化에 關與할 可能性이 예상되며 앞으로 硏究할 必要가 있다고 본다. 8. 腹部 第 6 神經球는 排糞機能에 影響을 미친다. This experiment was conducted to investigate the effects of Silkgland growth, Spinning quantity, Fibroin Component ratio, Cocooning shape and changing the pupa coloration by resecting abdominal 2nd, 4th and 6th ganglia at both the time of 5 instar awakened larva and matured larva in silkworm. The results were summarized as follows: 1. Silkland growth was showed that resecting abdominal 2nd ganglion was more effective than those of abdominal 4th and 6th ganglia. 2. The shape of silkland was appeared as serpentining by resecting ganglia. 3. Spinning quantity was revealed that resecting abdominal 2nd ganglion was less than those of abdominal 4th and 6th ganglia. 4. Silkland growth and spinning quantity were revealed the same tendency in degree of increase. 5. Fibroin Component ratio of brave was seemed that abdominal 6th ganglion was moe effective than abdominal 2nd and 4th ganglia. 6. In the case of resecting ganglia, flimsy cocoon was formed at upper parts of cocoon and half of pupa body was mostly observed staying outside of cocoon in the cocoon shape at lower part of abdominal 4th ganglia. 7. Abdominal 2nd, 4th and 6th ganglia were expected to have a close connection with pupation and changing the pupa coloration. 8. Furction of evacuation was seemed to be controlled by abdominal 6th ganglia.

Evaluation of GPU Computing Capacity for All-in-view GNSS SDR Implementation

Yun Sub Choi,Hung Seok Seo,Young Baek Kim 사단법인 항법시스템학회 2023 Journal of Positioning, Navigation, and Timing Vol.12 No.1

In this study, we design an optimized Graphics Processing Unit (GPU)-based GNSS signal processing technique with the goal of designing and implementing a GNSS Software Defined Receiver (SDR) that can operate in real time all-in-view mode under multi-constellation and multi-frequency signal environment. In the proposed structure the correlators of the existing GNSS SDR are processed by the GPU. We designed a memory structure and processing method that can minimize memory access bottlenecks and optimize the GPU memory resource distribution. The designed GNSS SDR can select and operate only the desired GNSS or desired satellite signals by user input. Also, parameters such as the number of quantization bits, sampling rate, and number of signal tracking arms can be selected. The computing capability of the designed GPU-based GNSS SDR was evaluated and it was confirmed that up to 2400 channels can be processed in real time. As a result, the GPU-based GNSS SDR has sufficient performance to operate in real-time all-in-view mode. In future studies, it will be used for more diverse GNSS signal processing and will be applied to multipath effect analysis using more tracking arms.

Between March and October 2007, a total of 516 blood samples from pigs in the Gyeonggi province were examined for seroprevalence against toxoplasmosis by latex agglutination test (LAT) and the detection of antigenic particles among seropositive samples by PCR. In the LAT, 118 (22.8%) were positive, and the unadjusted percentage of seroprevalence rates of breeding and fattening pigs were significant difference. Positive rate (14.1%) in the breeding pigs was much lower than that (27.8%) of the fattening pigs (p<0.001, Pearson`s Chi-square test). The antibody detection rate of sows was lower than fattening pigs, i.e., 15.8% (25/158) and 26% (93/358), respectively (P=0.011, Pearson`s Chi-square test). Among 118 seropositive samples by LAT, 68 (57.6%) were positive in PCR for the detection of the toxoplasma specific-DNA. There was a statistical difference in the positive PCR reaction between the raising pigs(63/93 67.7%) and sows (5/25, 20%) (P<0.01).

레비의 집단지성 : 대중지성을 넘어 전문가지성의 가능성 모색

최항섭(Hang Sub Choi) 사이버커뮤니케이션학회 2009 사이버 커뮤니케이션 학보 Vol.26 No.3

정보사회의 다양한 현상들을 설명해주는 개념으로 ‘집단지성’이 부각되고 있다. 집단지성은 정보기술을 활용하여 다양한 주체들이 서로의 경험, 정보, 지식을 공유하면서 새로운 지식을 생산해내는 것을 그 특징으로 한다. 최근 한국에서는 촛불집회 등 인터넷을 기반으로 한 시민사회적 현상을 설명하는 데 있어 집단지성 개념을 활용하고 있는 추세이다. 그런데 레비가 제시하고 발전시킨 집단지성에 있어서 그것이 ‘어떤 집단’이냐인가에 대해서는 이론적으로 보다 주의깊은 성찰이 요구된다. 먼저 레비는 초기 저작물을 통해서는 대중지성으로의 집단지성의 가능성을 열어 두었다. 대중의 지혜에 기반한 대중지성은 네트워크의 구조수평화, 탈근대에서의 권위해체화를 배경으로 새로운 지식생산의 주체로 부상할 잠재력이 충분하다는 것이다. 하지만 레비는 2000년대 이후의 논문들을 통해 오히려 전문가 지성 중심의 집단지성을 강조하고 있다. 그는 전문가들의 파편화, 귄위주의로 인해 전문가에 대한 신뢰가 하락하였음을 비판하면서, 이를 극복하는 방법으로 정보기술을 활용한 전문가 지성의 협업을 제기하였다. 전문가 지성의 협업은 전문가에게는 생존의 문제이며, 인류에게는 새로운 지식생산을 위해 반드시 필요한 것이다. This article looks into an aspect of meaning of collective intelligence, concept developed by Pierre Levy. Recently, this concept is often used to explain social phenomenons related to the civic movement via internet. Though, there has not been any attempt of theoretical approach on this concept. In his earlier articles, Levy seemed to have focused on the role of ‘ordinary people’ in collective intelligence. Collective intelligence is, in this context, nothing more than the intelligence of mass. Based on the network effect and post-modernity, collective intelligence as the intelligence of mass is being spot-lighted as the alternative subject to produce knowledge. However, in his late articles(after 2000’s), Levy emphasizes on the need of collaboration of so called ‘intellectuals’ and ‘experts’ in collective intelligence. So fragmented, intellectuals now should try to collaborate together sharing their data, information, and knowledge via information technology. It is indispensable to produce and create knowledge.

미래연구의 이론과 방법

최항섭 ( Hang Sub Choi ) 고려대학교 한국사회연구소 2012 한국사회 Vol.13 No.1

향후 사회과학연구에 있어서 미래연구와의 접목에 있어서 현재와 미래의 상호구성성 패러다임의 인식이 필요하다. 과거와 현재에만 주목할 수 밖에 없었던 사회과학 연구는 미래에 대한 통찰력과 대안제시에 보다 적극적일 필요가 있다. 뒤르켕의 사회적사실이 개인과 사회의 외부에 존재하면서 개인과 사회의 구성에 숙명적인 영향을 미친다면, 미래적사실을 현재의 개인들이 이를 인식하고 해석하면서 미래를 구성해나가는 데 결정적인 영향을 미친다. 미래연구의 방법론으로는 그 과정에 있어서 트렌드분석, 델파이분석, 교차분석이 있으며, 그 결과에 있어서 시나리오중심의 복수적, 토플러식의 단선적이 있다. 연구의 지향점과 특성에 따라서 이 방법론들을 조합적으로 사용할 수 있다. 미래연구의 주체에 있어서 복잡계로 진화하고 잇는 사회의 흐름을 보면 학계간 경계를 허문 상태에서의 전문가 집단지성이 요구된다. If sociology should be linked to Futures study in the future, the paradigm of "inter-construction" is required. Sociology, obliged to pay attention to ``past`` and ``present``, should be more active to suggest the picture of future. ``Social fact``, in durkheimien sense, has a inevitable influence on the construction of individual and society, ``Future fact`` make individuals in present recognize and interpret what will be in the future, and construct their future themselves. For the methodologies of futures study, there are trend analysis, dephi analysis, and cross factor analysis based on simulation. For the result of futures study, there are multi-result scenario, and one-way method. Finally, collective intelligence of specialists is very much asked to conduct futures study because our futures are becoming more and more complex world.
