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.

Optimization of Cellulase Production in Batch Fermentation by Trichoderma reesei

Yu, Xiao-Bin,Nam, Joo-Heon,Yun, Hyun-Shik,Koo, Yoon-Mo The Korean Society for Biotechnology and Bioengine 1998 Biotechnology and Bioprocess Engineering Vol.3 No.1

Maximum cellulase production was sought by comparing the activities of the cellulases produced by different Trichoderma reesei strains and Aspergillus niger. Trichoderma reesei Rut-C30 showed higher cellulase activity than other Trichoderma reesei stains and Aspergillus niger that was isolated from soil. By optimizing the cultivation conditions during shake flask culture, higher cellulase production could be achieved. The FP(filter paper) activity of 3.7U/ml and CMCase (Carboxymethylcellulase) activity of 60U/ml were obtained from shake flask culture. When it was grown in 2.5L fermentor, where pH and DO levels are controlled, the enzyme activities were 133.35U/ml (CMCase) and 11.67U/ml(FP), respectively. Ammonium sulfate precipitation method was used to recover enzymes from fermentation broth. The dried cellulase powder showed 3074.9U/g of CMCase activity and 166.7U/g of FP activity with 83.5% CMCase recovery.

Protection and Dissection of Recurrent Laryngeal Nerve in Salvage Thyroid Cancer Surgery to Patients with Insufficient Primary Operation Extent and Suspicious Residual Tumor

Yu, Wen-Bin,Zhang, Nai-Song Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.17

Some thyroid cancer patients undergone insufficient tumor removal in the primary surgery in China. our aim is to evaluate the impact of dissection of the recurrent laryngeal nerve during a salvage thyroid cancer operation in these patients to prevent nerve injury. Clinical data of 49 enrolled patients who received a salvage thyroid operation were retrospectively reviewed. Primary pathology was thyroid papillary cancer. The initial procedure performed included nodulectomy (20 patients), partial thyroidectomy (19 patients) and subtotal thyroidectomy (10 patients). The effect of dissection and protection of the recurrent laryngeal nerve and the mechanism of nerve injury were studied. The cervical courses of the recurrent laryngeal nerves were successfully dissected in all cases. Nerves were adherent to or involved by scars in 22 cases. Three were ligated near the place where the nerve entered the larynx, while another three were cut near the intersection of inferior thyroid artery with the recurrent laryngeal nerve. Light hoarseness occurred to four patients without a preoperative voice change. In conclusion, accurate primary diagnosis allows for a sufficient primary operation to be performed, avoiding insufficient tumor removal that requires a secondary surgery. The most important cause of nerve damage resulted from not identifying the recurrent laryngeal nerve during first surgery, and meticulous dissection during salvage surgery was the most efficient method to avoid nerve damage.

( Yu Bin Kim ),( Shan Randima Nawarathne ),( Hyun Min Cho ),( Jun Seon Hong ),( Jung Min Heo ),( Jiseon Son ) 한국축산학회 2022 한국축산학회지 Vol.64 No.1

The current study was conducted to evaluate the effect of calcium-enriched fatty acid supplementation on the growth performance, blood metabolites, intestinal morphology, carcass traits, and nutrient digestibility of broilers subjected to chronic heat stress. A total of 210 one-day-old broiler chicks (40.12 ± 0.25 g) were randomly allocated to one of five dietary treatments, to obtain six replicates per treatment. Broilers were subjected to chronic heat stress from day 21 to day 35, post-hatching, at 34℃ for 9 h per day. The body weight (BW) and feed intake of the experimental broilers were recorded weekly, and the average daily gain (ADG) and feed conversion ratio (FCR) were calculated accordingly. Rectal temperature was measured to compare the basal body temperatures between individuals, and blood samples were collected on days 21 and 35 to evaluate basal body temperature, serum total cholesterol, and the triglyceride content of the broilers. On days 21 and 35, one broiler from each cage (n=6) was euthanized to measure carcass trait parameters, nutrient digestibility in digesta, and intestinal morphology. On days 14, 28, and 35, the broilers fed 2.0% calcium-enriched fatty acids had higher BW (p < 0.05) than those fed the other diets. However, no differences (p > 0.05) were found in the average daily feed intake (ADFI) between dietary treatments over the 35 experimental days. On the other hand, on day 21, post-hatching, the broilers fed the 2.0% calcium-enriched fatty acid diet had improved (p < 0.05) dietary feed efficiencies compared to the other treatments. On day 28, the broilers fed the 5.0% of calcium-enriched fatty acid diet also had higher (p < 0.05) dietary feed efficiencies than those fed with the other dietary treatments. No effects (p > 0.05) on carcass weight, nutrient digestibility, intestinal morphology, or blood parameters were found between broilers fed with dietary treatments. This study demonstrated that the inclusion of an additive, containing 2.0% calcium-enriched fatty acid, to broiler diet could ameliorate the negative growth performance of broilers; and no interaction (p > 0.05) was observed between the calcium-enriched fatty acid and nutrient digestibility, digestive anatomy, blood metabolism, and carcass traits of broilers subjected to chronic heat stress conditions for 35 days post-hatching.

Bin Li,Rongrong Yu,Yu Shi,Ting Su,Fang Wang,Muhammad Ibrahim,Guanlin Xie,Yanli Wang,Guochang Sun 한국식물병리학회 2011 Plant Pathology Journal Vol.27 No.4

Bacterial leaf spot of Euphorbia pulcherrima has been reported in many countries. Characterization by polyphasic approaches indicated that the isolates from India, USA and New Zealand could be distinguished based on rep-PCR profiles and gyrB phylogenies, while the Chinese isolates should be ascribed to Xanthomonas axonopodis pv. poinsettiicola.
