다큐멘터리 재현양식 연구 : <워낭소리>와 <택시 블루스>를 중심으로

민환기,이유빈 영상예술학회 2009 영상예술연구 Vol.15 No.-

다큐멘터리가 묘사하고자하는 사람이나 사건은 현실에 실제로 존재한다. 픽션 영화의 인물이나 장소가 허구의, 만들어진 존재임에 반하여 다큐멘터리가 묘사하는 대상은 다큐멘터리의 묘사와는 상관없이, 또는 다큐멘터리가 그 존재를 묘사하지 않았을 때에도 존재한다. 하지만 현실에 존재하는 대상을 재현하기 위해서는 인공적인 장치에 의존해야 한다. 그 장치는 재현해야 하는 현실의 속성과는 다른 종류의 미학적인 장치이다. 그렇기 때문에 미학적인 장치를 통한 재현은 현실을 지시하면서도 왜곡하거나 변화시킬 가능성을 처음부터 안고 출발한다. 본 글은 <택시 블루스>와 <워낭소리>의 재현양식의 분석을 목표로 한다. 두 영화 모두 혼합된 다큐멘터리 양식을 사용하면서 다큐멘터리가 가진 표현양식의 한계를 넘어서려고 시도했다. 그 결과로 <택시 블루스>는 픽션이냐 아니냐 하는 논란에 휩싸였고 <워낭소리>는 다큐멘터리로서는 드물게 300만 관객을 동원하는 대중적 성공을 거두었다. 물론 재현양식이 그 결과를 모두 설명할 수 있는 것은 아니겠지만 두 영화가 가지고 있는 장점과 단점은 많은 부분 특정한 재현양식의 차용과 그것의 변형에서 비롯된다. 빌 니콜스(Bill Nichols)의 재현양식의 구분을 따라서, 두 영화가 차용한 지배적인 재현양식과 그것의 변형이 어떤 목적을 위해서 어떻게 사용되었고 그것의 효과가 무엇인지를 그리고 그러한 재현양식이 현실과 맺는 관계를 분석한다. A documentary film describes people or events being in the world. People or events in the documentary have existed without such a description unlike people or events in the fiction film. To represent things in the world depends on artificial devices different from things in their nature. Because of it, things described are always both an indication and a distortion of things in the world. I try to analyse Taxi Blues and An old partner in terms of representational mode. Both films try to negotiate confliction between the real and its representation with mixed representational mode. it produced a huge success of An old partner in box office and critical debates on Taxi Blues. Although it is not sufficient to explain all the issues related to both films by analysis of their representational mode, I believe it can hint its success and failure of each film regarding such a negotiation and enrich discourses on documentary film-making in Korean soil. With Bill nichols's categorization, I will analyse both films' representational mode, and its effect on the real and its representation, and the audience.

이혁,김유광,김경빈 大韓神經精神醫學會 1991 신경정신의학 Vol.30 No.1

This study was attempted to clarify sociopsychiatric characteristics according to the class of psychoactive substances which were classified into 8 groups such and methamphetamin, cocaine, inhalants(bond/gas), dextromethorphan(Romilar), sedatives marijuana, analgesics and etc. The data of the study were collected from 134 psychoactive substance abusers(89men, 45women), who had admitted to SNMH during past 5 years. The results were as follows ; 1) The mean age of patients was 26.5±9.6 years and according to the class of psychoactive substance, inhalant and dextromethorphan abusers were significantly younger than sedatives and analgesics abusers(P〈0.01). 2) 43.1% of patients were grown up in broken family until puberty and 27.9% of married patients showed unstable marital state such as a divorce or seperation. 3) 41.4% of patients had past history of delinquent behavior and especially, inhalants and dextromethorphan abusers had more past history of delinquent behavior than sedatives and analgesics abusers(P〈0.01). 4) The main motive of mitiation of psychoactive substance was peer pressure, relief of psysical symptoms, curiosity in that order. 75% of inhalants abusers were itiated by peer pressure, but most of sedatives and analygesics abusers used it for the purpose of relieving of physical symptoms, and methamphetamine abusers used it mainly due to peer pressure or for the purpose of increasing sexual plesure(P〈0.01). 5) 57.5% of patients reported the experience of unwanted response such as unpleasant hallucinatory state, loss of control, and psychotic state after use of psychoactive substances. Especially the unwanted respose was reported more frequently in methamphetamin and inhalants abusers. 6) 38.5% of patients abused more than two classes of psychoactive substances, and their significant combination types were not found but inhalant-dextromethorphan, analygesics-sedatives and methamphetamine-marijuana combination types were relatively common.

홍성찬,김영빈,정동혁,박병근,김유성,이성진 원광대학교 체력과학연구소 2008 體力科學硏究 Vol.30 No.1

The present study aims to explore the effects of applying spheroid-combined stimulating therapy on body composition. For this aim. 20 persons were selected as subjects and 10 of them each were assigned to the experimental group and control group, respectively. The experimental group was applied a 12-week combined stimulating therapy and changes in physical constitution of the members were measured before application and 4, 8 and 12 weeks after application. From the study, following conclusions could be drawn: First, body weights of the experimental group decreased from 59.9kgs before application of the spheroid-combined stimulating therapy to 57.2kgs 12 weeks after application, no significant but 4.51% change. Second, body fats of the experimental group changed from 18.8kgs before application to 16.4kgs 12 weeks after application, no significant but 12.77% reduction. Third, % fats of the experimental group decreased from 31.2% before application to 28.6% 12 weeks after application, no significant change but 8.33% reduction. Fourth, body mass index(BMI) of the experimental group decreased from 23.23 kg/㎡ before application of the therapy to 21.43kg/㎡ after application, no significant but 8.03% reduction. As seen above, the 12-week application of the spheroid-combined stimulating therapy produced no significant changes in physical constitution as physical exercise did, but improved physical constitution by reducing certain amount of boy weight, body fat, % fat and BMI. In order to detect more positive and significant changes in physical constitutions, continued studies and clinical experiments should be performed to more diverse subjects using technically reinforced equipment for spheroid-combined stimulating therapy.

Yu-Bin Park,Eui-Yong Hong,In-Yong Jeong,Yoon-Jin Park,Tae-Seok Oh,Myoung-Jun Jang 한국버섯학회 2022 버섯 Vol.26 No.1

In this study, pH 5, 6, 7, 8, 9, 10 in each of two organic nitrogen source medium (Mushroom minimal medium + Yeast extract (YE), ST (mushroom minimal medium + Soytone) and MCM (mushroom complete medium) medium) 3 types of mycelium of 'Lepista nuda', WT (Wild type), LN96 (Lepista nuda 96), and LN103 (Lepista nuda 103), respectively, were inoculated and inoculated with a 3 day interval for 15 days. to investigate the mycelial growth length. As a result of checking the growth length of the mycelium on the 12th day, 3 days before the end of the experiment, it was confirmed that the mycelial growth rate was faster in YE pH8 medium for WT, MCM pH8 medium for LN96, and YE pH10 medium for LN103 compared to the untreated PDA. WT was confirmed to grow faster than PDA at pH 8, LN96 at pH 7, 8, 9, and LN103 at pH 6, 7, 8, 9, and 10. Based on this, it is judged that the mycelium of the spearmint mushroom has a faster growth rate in an organic nitrogen source medium than in PDA in basic rather than weakly acidic.

Yu Bin Seo,Su-Jin Moon,Chan Hong Jeon,Joon Young Song,Yoon-Kyoung Sung,Su Jin Jeong,Ki Tae Kwon,Eu Suk Kim,Jae-Hoon Kim,Hyoun-Ah Kim,Dong-Jin Park,Sung-Hoon Park,Jin Kyun Park,Joong Kyong Ahn,Ji Seon 대한류마티스학회 2020 대한류마티스학회지 Vol.27 No.3

To develop a clinical practice guideline for vaccination in patients with autoimmune inflammatory rheumatic disease (AIIRD), the Korean College of Rheumatology and the Korean Society of Infectious Diseases developed a clinical practice guideline according to the clinical practice guideline development manual. Since vaccination is unlikely to cause AIIRD or worsen disease activities, required vaccinations are recommended. Once patients are diagnosed with AIIRD, treatment strategies should be established and, at the same time, monitor their vaccination history. It is recommended to administer vaccines when the disease enters the stabilized stage. Administering live attenuated vaccines in patients with AIIRD who are taking immunosuppressants should be avoided. Vaccination should be considered in patients with AIIRD, prior to initiating immunosuppressants. It is recommended to administer influenza, Streptococcus pneumoniae, hepatitis A, hepatitis B, herpes zoster, measles-mumps-rubella virus, human papillomavirus, and tetanus-diphtheria-pertussis vaccines in patients with AIIRD; such patients who planned to travel are generally recommended to be vaccinated at the recommended vaccine level of healthy adults. Those who live in a household with patients with AIIRD and their caregivers should also be vaccinated at levels that are generally recommended for healthy adults.

PoW-BC: A PoW Consensus Protocol Based on Block Compression

( Bin Yu ),( Xiaofeng Li ),( He Zhao ) 한국인터넷정보학회 2021 KSII Transactions on Internet and Information Syst Vol.15 No.4

Proof-of-Work (PoW) is the first and still most common consensus protocol in blockchain. But it is costly and energy intensive, aiming at addressing these problems, we propose a consensus algorithm named Proof-of-Work-and-Block-Compression (PoW-BC). PoW-BC is an improvement of PoW to compress blocks and adjust consensus parameters. The algorithm is designed to encourage the reduction of block size, which improves transmission efficiency and reduces disk space for storing blocks. The transaction optimization model and block compression model are proposed to compress block data with a smaller compression ratio and less compression/ decompression duration. Block compression ratio is used to adjust mining difficulty and transaction count of PoW-BC consensus protocol according to the consensus parameters adjustment model. Through experiment and analysis, it shows that PoW-BC improves transaction throughput, and reduces block interval and energy consumption.

TAZ as a novel regulator of oxidative damage in decidualization via Nrf2/ARE/Foxo1 pathway

Yu Hai-Fan,Zheng Lian-Wen,Yang Zhan-Qing,Wang Yu-Si,Wang Ting-Ting,Yue Zhan-Peng,Guo Bin 생화학분자생물학회 2021 Experimental and molecular medicine Vol.53 No.-

TAZ, as a crucial effector of Hippo pathway, is required for spermatogenesis and fertilization, but little is known regarding its physiological function in uterine decidualization. In this study, we showed that TAZ was localized in the decidua, where it promoted stromal cell proliferation followed by accelerated G1/S phase transition via Ccnd3 and Cdk4 and induced the expression or activity of stromal differentiation markers Prl8a2, Prl3c1 and ALP, indicating the importance of TAZ in decidualization. Knockdown of TAZ impeded HB-EGF induction of stromal cell proliferation and differentiation. Under oxidative stress, TAZ protected stromal differentiation against oxidative damage by reducing intracellular ROS and enhancing cellular antioxidant capacity dependent on the Nrf2/ARE/Foxo1 pathway. TAZ strengthened the transcriptional activity of Nrf2 which directly bound to the antioxidant response element (ARE) of Foxo1 promoter region. Additionally, silencing TAZ caused accumulation of intracellular ROS through heightening NOX activity whose blockade by APO reversed the disruption in stromal differentiation. Further analysis revealed that TAZ might restore mitochondrial function, as indicated by the increase in ATP level, mtDNA copy number and mitochondrial membrane potential with the reduction in mitochondrial superoxide. Additionally, TAZ modulated the activities of mitochondrial respiratory chain complexes I and III whose suppression by ROT and AA resulted in the inability of TAZ to defend against oxidative damage to stromal differentiation. Moreover, TAZ prevented stromal cell apoptosis by upregulating Bcl2 expression and inhibiting Casp3 activity and Bax expression. In summary, TAZ might mediate HB-EGF function in uterine decidualization through Ccnd3 and ameliorate oxidative damage to stromal cell differentiation via Nrf2/ARE/Foxo1 pathway.
