This study is a link in a chain which grope for the description of puppet performance history. This study imply my intention which is not a description of puppet performance 'history' but a description of 'puppet performance' history. Object materials of this study is materials connected with puppet performance from ancient times to Chosun dynasty. Object materials of this study include not only records but also remains and pictures. Discussion start with regulation of puppet performance materials and establishment of a classification criterion. As a result of that discussion, the age of puppet performance is as follows: 'the age of diverse use of puppet', 'the age of ritual puppet performance of worship', 'the age of play puppet performance of handling', 'the age of ritual puppet performance of display', 'the age of ritual puppet performance of expulsion', 'the age of ritual puppet performance of handling', 'the age of play puppet performance of display', 'the age of play puppet performance of handling and voice-acting'. According to the internal division of age, the description of puppet performance history which is spread chronologically is attempted. As a result of the description, I confirm that puppet performance reveal a one's unfolding process. And a distinct aspect from the general cultu! re history is found. The development process which is a changeover that is 'from ritual puppet performance to play puppet performance' is amended by a circulation of ritual puppet performance and play puppet performance'. And the development process which is a changeover 'from static puppet to dynamic puppet' is amended by a circulation of static puppet and dynamic puppet'. Like this the thing which is laid in the inside which is not a one sided changeover but is a circulation is said that from one age of puppet performance to other age of puppet performance is not a close of former puppet performance tradition. Unfolding from one age to other age, on the other hand former puppet performance reveal aspect which is a continuance and change with a one's vitality. And a relation of mutual influence is exist between the ritual puppet performance and the play puppet performance on a large scale, among the puppet performance types on a small scale. this also don't overlook in cas! e of a groping of puppet performance history.

The blends of waste-polyethylene (W-PE)/waste-ethylene vinyl acetate copolymer (W-EVA) with inorganic and phosphorous flame retardants (i.e., aluminium hydroxide, magnesium hydroxide, and so on) were prepared by melt mixing techniques at different compositions and foamed. The flame retardancy and foaming properties of the blends, limiting oxygen index (LOI), heat release rate (HRR), carbon monoxide yield (COY), total heat release (THR), effective heat of combustion (EHC), expandability and cell structure were investigated using cone calorimeter, SEM, LOI tester and polarizing microscope. When the composition ratios of the W-PE/W-EVA blends were 50/50 (w/w), and the ranges of the flame retardants contents were $175{\sim}220 phr$, we could obtain foams with the uniform and closed cell, high expandability (1900 % or more), high LOI, and low HRR values. These results depend on crosslinking and loaming conditions, a char formation and smoke suppressing effect. Aluminium hydroxide had more effect in the increase of LOI than magnesium hydroxide, while magnesium hydroxide considerably affected the decrease of HRR and COY.

This study was conducted to investigate the staging principle, the staging work and the trial performance of Shingeuk troupe Geukyesulyeonguhoe during the period of coterie system, focusing on Gogol work·Ham Daehoon translation·Hong Haeseong directing's (5Act). As a result, the first trial performance was based on a faithful full-scale description rather than an interpretive directing of play. It was a performance that focused on copying and implanting the external form of the performance stage of Shingeki troupe Tsukiji Little Theater. The general review of the time was summarized to the point that it was a relatively successful performance that exceeded expectations as a trial demonstration of amateur actors. However, in terms of the content of play and the form of performance, reservations and lack of contemporary(modern) interpretation caused the problem that the general audience was alienated. Therefore, it was difficult to achieve the effect of reflecting the reality of Chosun through , as Geukyesulyeonguhoe intended.

해외투자로 인해 수출 및 고용이 감소할 것이라는 우려가 있다. 본고는 이론적, 통계적, 실증적 분석을 통하여 이에 관한 논의를 하고 향후 전망과 함께 정책적 시사점을 도출하는 것을 목적으로 한다. 본고의 분석결과 및 투자제도 개선방향을 요약하면 다음과 같다. 해외투자가 아직까지 수출을 대체하였다는 근거는 없다. 향후 국내부품업체의 현지동반진출 확대, 해외자회사의 역할 증대, 국제분업생산체제의 진전 등 해외투자전략의 변화에 따라 해외투자가 수출을 대체할 가능성을 배제할 수 없으나 해외투자의 제한시에는 수출 및 고용에 더욱 악영향을 줄 수 있다. 해외투자를 제한하는 것은 예상되는 실업을 단지 연기시키는 것에 불과하며, 오히려 향후 실업문제가 훨씬 심각해질 수 있다. 해외투자는 기업의 경쟁력 유지 및 구조조정을 위해서는 타대안보다 고용안정에 기여할 수 있다. 또한 과도한 해외투자가 기업 및 국내경제에 미칠 악영향을 우려하여 해외투자를 규제하는 것도 설득력이 약하다. 정부가 해외투자의 과도성 여부를 판달할 능력이 기업보다 우월하다고 할 수 없다. 설령 해외투자 결정이 비합리적으로 이루어질 가능성이 있다 하더라도, 이 문제는 투자기업 및 여신은행 등의 책임을 분명히 하여 기업은 투자성과의 책임을 지고, 여신은행, 채권자 등은 투자기업의 재무현황 및 투자계획의 성공가능성을 고려하여 자금제공을 하도록 유도해야 한다. 따라서 일부 대규모 해외투자에 대한 사전심의로 대표되는 현행규제는 철폐되어야 한다. 일부 대규모 해외투자의 적정성 여부를 판단하기 위해 운용되고 있는 해외투자 심의는 실효성이 없을 뿐만 아니라 신속한 해외투자결정을 방해할 수 있다. 중장기적인 관점에서 해외투자로 인한 국제분업을 국내고용 및 수출의 증가뿐만 아니라 경제성장으로 연결시키기 위해서는 국내의 입지여건을 혁신활동 및 고부가가치 활동에 적합하도록 개선해 나갈 필요가 있다. 한편 단기적 고용감소에 대비한 정책도 필요한데, 고육훈련제도의 개선, 노동시장의 유연성 제고, 고용서비스 개선은 이런 마찰을 완화하는데 기여할 것이다.

The combustion characteristics of cypress wood coated with boric acid (BA) and ammonium pentaborate (APB) were examined using a cone calorimeter according to the ISO 5660-1 standard. As a result, the combined specimens of boric acid and ammonium pentaborate (BA/APB) led to an improved fire performance index due to their synergistic effect. In addition, the total heat release values of the specimen coated with the boron compounds were 6.1~14.1% lower than that of the base specimen. The total smoke release rate (TSR) of the specimens coated with the boron compound decreased throughout the combustion process, except for BA/APB. The maximum concentration of carbon monoxide was reduced by 15.8~25.5%. In general, wood treated with flame retardants has a lower fire hazard.

The application of RECON(Reconstituted tobacco sheet) and the ventilation technology has been considered as very useful methods for controlling the tar and nicotine deliveries in modern blended tobacco. In this study, the effects of RECON contents in simulated blends on the smoke delivery and burning temperature were evaluated in three different ventilation levels. The ventilation showed a great influence on the burning temperature and smoke deliveries. The nicotine, tar and CO deliveries was greatly reduced by the ventilation. The amount of RECON showed the minor impacts on the smoke delivery. In high ventilation level such as 85 % ventilation, there was no distinct change in smoke deliveries by the amount of RECON.

To assess the impact of molinate on freshwater aquatic organisms, acute and chronic toxicity studies for waterfleas were conducted. In acute toxicity studies for Daphnia magna, and Moina macrocopa, the 48-h $EC_{50}$ values were 11.4 and 8.3 mg/L respectively. And in reproduction toxicity studies for the same species, the NOEC's were 2.5 and 2.0 mg/L respectively. These results suggest that waterfleas have simillar sensitivity to molinate. On the other hand, the NOEC for 3-generation toxicity of moina macrocopa 0.16 mg/L, was much lower than those of acute values. This studies concludes that molinate has minimal risk to waterfleas in river.

본 연구에서는 금강의 하류부의 시간적 공간적 수질변화를 자세하게 분석하기 위하여 3차원 수리동역학 모델인 EFDC 와 비정상상태 수질모델인 WASP 7.2와 를 연계 적용하였다. 본 연구의 대상 구간은 금강하류 부중 대청댐 조절지 방류구 지점부터 공주의 정안천 유입 직전까지 총 48km의 구간이다. 하천의 수심별 수질은 일정하다고 가정하였으나 폭방향의 수질은 좌 중 우로 3개의 소구간으로 나누고 하천의 흐름 방향으로 나누어 전체적으로는 2차원적으로 구분하였다. 하천의 바닥 형상을 이용하여 모델 격자를 구성하였으며 수리모델은 건교부의 수위자료를 이용하여 보정하였고 수질자료는 환경부의 수질측정망 자료를 이용하여 보정하였다. 2차원 수리동역학-수질 연계모델링 결과, 대전 갑천이 유입되고 난 후의 청원지점에서 그리고 청주지역의 영향을 포함하는 미호천이 유입되고 난 연기 지점 그리고 본 연구의 최하류인 공주지점에서는 하천의 폭 방향으로 상당한 수질 차이가 있음을 확인하였다. 이는 대전 갑천 또는 청주 미호천 등이 유입된 이후 효과적으로 혼합되지 않는다는 것을 의미한다. 이는 해당지역의 수질시료 채취 위치에 따라 수질에 현격한 차이가 있을 수 있다는 것을 나타내며, 현재 환경부 수동측정망의 시료채취 방법을 고려하여 볼때 하천수질의 대표성을 나타낼 수 있는가 하는 문제의 차원에서 매우 심각하게 받아들여져야 할 것으로 생각된다. 한편, 현재 우리나라에서 시행되고 있는 오염총량관리제나 대부분의 환경영향평가에서는 하천의 폭 방향의 수질 차이에 대한 고려가 전무하며 이에 대한 전면적인 재검토가 시급하다고 판단된다.

This study is carried out to critically explore the direction of the improvement of the protection clauses of minor artists which is the core of Popular Culture Art Industrial Development Act enforced from July 29, 2014. The analysis shows that the law accepted the social issues such as the prevention of procuring minor prostitution, slave contracts(unfair long-term contracts), and third party's profit-extortion. However, the law missing or not specifically stated about age-based differential enforcement of work hours, dangerous acting scenes shouldn't be forced to minors, right to sleep, health, and study, as well as the penalty regulations in violation of each clause. Consequently, the Act's revision and supplementation is necessary to fully meet above insufficiencies referring to foreign practices.

This study was conducted to evaluate the effect of cigarette papers, flax and wood, on the delivery of mainstream smoke. The main components of cigarette papers were cellulose, hemicellulose, lignin, and pectin. Lignin contents, known as precursor of smoke's phenolic compounds, of the flax and wood cigarette papers were 5.8% and 10.6%, respectively. The pyrolysis products of cigarette papers were similar by the profile of total ion chromatogram. But, the area % of some components, such as 1,3-cyclopentanedione, 3,5- dimethyl cyclopentane-1,2-dione, 2-hydroxy-3-methyl-2-cyclopentenone, dihydro-2(3H)-furanone, 3-methyl-2(5H)-fruanone, and 5-methyl-2-furaldehyde delivered through pyrolysis of the flax cigarette paper were higher than that of wood cigarette paper. Otherwise, the area % of some components, such as 2-methyl-cyclopentene-l-one), 2,3-butanedione, 2-cyclopentene-l-one, and 5-hydroxy-2-methyl-furaldehyde, 2-furaldehyde delivered through pyrolvsis of the wood cigarette paper were higher than that of flax cigarette paper. To identify the difference between two cigarette papers, we used the cigarette column filled with the cut cigarette paper instead of the cut tobacco leaf. The amounts of semi-volatile fraction delivered from flax cigarette paper was more than that of wood cigarette paper. But, by using the cut tobacco, there was no big difference of delivery amount between flax and wood cigarette papers. Also, aroma of TPM by collecting from brening cut tobacco wrapped in flax and wood papers showed a different pattern by the electonic nose system. Although the difference between two cigarette papers by using the cut tobacco was smaller than that of cut cigarette paper, this result indicated that the fax and wood had the different effects on the delivery of smoke components as shown in the sensory test results.
