Effects of ICT Device Ownership on Consumers` Digital Piracy Behavior

( Hyeon Bo?kim ),( Jung Hoon Moon ) 한국정보시스템학회 2014 情報시스템硏究 Vol.23 No.4

This study investigates how information and communication technology (ICT) can damage intellectual property rights (IPR) in the movie industry. Utilizing a survey questionnaire to gather information about the extensive use of ICT devices, including tablet PCs and smartphones, we demonstrate how digital piracy behavior is associated with various socio-demographic characteristics. Econometrically, since a large number of people do not engage in piracy activities, we adopt a zero-inflated negative binomial model. We find that people with tablet PCs are more likely to engage in the piracy of movies from peer-to-peer (P2P) sites. In particular, when we categorize ICT devices based on whether they are portable and allow downloads, we find that people with devices equipped with both functions are most likely to engage in movie piracy.

이영훈의 노랫말에 나타난 유동적(流動的) 풍격미

안시현(Ahn, Si-hyeon),김동문(Kim, Dong-moon) 한국문화융합학회 2018 문화와 융합 Vol.40 No.5

1980년 중반에 나타난 이문세의 발라드는 이문세만의 감성을 살리어 새로운 팝 발라드를 형성함으로써 ‘팝 발라드의 원조’로 불리었다. 그것은 이영훈이란 작가와 이문세라는 가수의 콤비가 만났기 때문에 가능한 것이다. 따라서 이문세의 노래를 아름답게 만들어준 이영훈이라는 작가에 대한 심미의식을 고찰하는데 연구의 목적을 두고 고찰하였다. 연구방법은 이영훈의 생애를 살펴보고, 1985~1988년 사이의 작품 중 이문세가 노래하고 이영훈이 작사, 작곡한 곡 중 시간적 흐름이 표현된 작품을 구체적으로 분석하여, 동양적 관점에서 문학의 대표적 미학범주인 당나라 사공도(司空圖)의 이십사시품(二十四詩品) 중 유동(流動)의 미학범주를 적용하여 탐색하였다. 대중음악평론가 박준흠은 이영훈과 이문세를 일컬어 “1980년대 주류음악 신 최상의 작품 생산 콤비”라고 하였다. 그는 왜 ‘신’이란 관형사를 붙였을까에 대한 의문을 갖고 이영훈의 작품내용을 분석한 결과 사랑과 이별에 대한 내면의 심상을 시간적 흐름에 맞추어 표현함으로써 멈춤이 아닌 지속성을 유추할 수 있었고, 이를 살아 움직이는 생명의 유동적 풍격미로 정의하였다. 무엇보다 이영훈의 시를 이문세가 80년대 이전의 트로트와는 달리 지성, 이성, 감성이 혼융된 ‘발라드풍’으로 노래함으로써 ‘발라드의 원조’로 평가 받게 되면서 ‘신’이란 단어가 붙여 진 듯하다. In the mid-1980s, a songwriter, Lee Young-hoon, and singer, Lee Moon-sae was called as a pioneer of pop ballads. Even though ir is very difficult for a singer to always perform in a new way, Lee Moon- sae gave new performance all the time. This may have been possible due to Lee Young-hoon who beautifully wrote songs for Lee Moon-sae, and therefore, this article aimed to study the aesthetic sense of Lee Young-hoon. The article analyzed the life of Lee Young-hoon and his 4 representative songs, and apply an aesthetic category of flow among Twenty-four Poems made by Sagongdo in the Chinese Tang Dynasty. A pop music critic, Park Joon-heum referred Lee Young-hoon and Lee Moon-sae as “a duo to produce the best songs, a god of mainstream music in the 1980s.” To answer a question why he called them a ‘god’, Lee Young-hoon’s songs were closely analyzed. As a result, it can be inferred that the songs symbolize continuity of the narrator s mind, by expressing intrinsic images of love and style of the vigorous movement of life. Above all, unlike Korean trot prior to the 1980s, Lee Moon-sae sung Lee Young-hoon’s lyrics in ‘a ballad style’ that combined intelligence and rationality with sensitivity, giving him a title, ‘a pioneer of ballad’. This may have named them as a ‘god’.

하위문화를 중심으로 현대패션에 나타난 크로스오버(Crossover)에 관한 고찰

김문숙,김현주 서울여자대학교 자연과학연구소 1997 자연과학연구논문집 Vol.8 No.-

Crossover is the coordination of a different items and the ideas of opposite elements from other themes and arts. This study examine a concept and existence factors of crossover through a social phenomenon, and look into a representative character of crossover on the sub-culture. The crossover at the end of 20th century of fashion is concerned with a repulsion of Modernism and a acceptance of Post-modernism. The crossover can be defined in many variables, such as a sex, area, nation and any other idea. The crossover in modern fashion reflects the spirit of 20th century society and culture, and performs various functions as follows, expression of fun, change in gender roles, expression of inner consciousness and pursuit of ideal human type.

Surface Structures of CoOx/TiO2 Catalysts for Continuous Wet Oxidation of TCE

김보례,김문현 대구대학교 환경기술연구소 2005 미래환경기술 Vol.1 No.2

XRD and XPS measurements have been conducted to characterize a fresh 5% CoO_(x)/TiO₂ and the spent catalyst used for the wet TCE oxidation at 310 K for ca. 6 h. The XPS spectra of the both sample gave significant difference in surface spectral features for CoO_(x) species. The binding energy for Co 2p_(3/2) of the fresh catalyst appeared at 781.3 eV, which was very similar to the chemical states of CoTiO_(x) such as Co₂TiO₄ and CoTiO₃. The spent catalyst indicated a 780.3-eV main peak for Co 2p_(3/2) with a satellite structure at a higher energy region and this binding energy was almost equal to that of Co₃O₄ among reference Co compounds used here. XRD measurements for fresh and used 5% CoO_(x)/TiO₂ catalysts represented the phase structure of Co₃O₄ even before reaction, as revealed by a comparison with the reference Co compounds. Based on these XPS and XRD results, a tenable model structure of CoO_(x) species existing with the fresh catalyst can be proposed to be predominantly Co₃O₄ encapsulated completely by very thin film-like CoTiO_(x) consisting of Co₂TiO₄ and CoTiO₃ (Type A), with a very small amount of Co₃O₄ covered partially by such cobalt titanates (Type B) which may be responsible to the initial catalytic activity. Such CoTiO_(x) overlayer on Co₃O₄ particles may be readily removed into the wet media for the initial reaction period at 310 K, thereby giving rapid increase in the catalyti cactivity up to 1 h, as indicated during the heterogeneous wet catalysis. This model can offer reasonable explanation on the earlier activity profile of 5% CoO_(x)/TiO₂ catalyst for the wet TCE oxidation at 310 K.

벽체에 작용하는 토압에 관한 모형실험

김문규,김대현 동의공업대학 2000 論文集 Vol.26 No.1

The model experiments were carried out to observe the variation of lateral earth pressure acting on the wall as vary the constraint of retaining wall, geometry of wall, and backfill width. For the experiments, a soil-box, model wall, and a rainer were designed and manufactured. The experiments were carried out with two different types of constraint on wall movement: i.e. first with completely fixed wall and second with movable wall depending on soil pressure. The measured lateral earth pressure was compared with that by an extended silo and wedge theories. The test results are summarized as follows: The measured lateral earth pressure approached to that from the extended silo theory as a narrower backfill width was used. Both experimental and theoretical results showed a good coincidence when the backfill width is Bc tan(45 -?? DS/2)H. But much deviated from that by an extended wedge theory. (원문을 참조하세요)

In order to elucidate the effect of planting arrangements on the yearly changes in yield characters, suckers of ‘Dwarf Cavendish ’ banana(Musa cavendishii Lamb.) were planted by the oblong(2.45 ×1.25m), triangular(1.75 ×1.75m), and square(1.75 ×1.75m) arrangements in March 1985, in the green house at The Research Institute for Subtropical Agriculture, Cheju National University, Cheju, Korea. Yield characters of two generations (plant and ratoon crops) were analyzed. The results obtained are summarized as follows; 1. More days from bunch head emergence to maturity were required in ratoon crop than in plant crop. No significant differences were recognized among planting arrangements. 2. While the fruit stalk was longer in ratoon crop than in plant crop, fruit bearing axis was longer in plant crop. 3. Number of fingers per hand or per bunch was not significantly different between generations and among planting arrangements. The diameter of finger in ratoon crop was wider than that in plant crop. 4. The weight of bunch in ratoon crop was heavier than that in plant crop. 5. The effect of planting arrangements on the bunch weight was remarkable in ratoon crop, and heavier bunch was obtained by the oblong and square arrangements.

저혈청 배지에서 인간 전골수세포(HL-60)를 이용한 tPA 생산과 세포사멸기작에 관한 연구

김현구,성기돈,김태호,안주희,함문선,박진서,이현용 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.1

tPA 생산과 세포 사멸의 연구를 하기 위해서 인간 전골수세포가 배양되었다. 연속 관류 배양하에서 최대 tPA 생산량은 324 ng/ml이며 최대 세포 농도는 5.27×10 exp (6) cells/ml였다. Phorbol ester를 넣었을 때 tPA 생산량은 420 ng/ml까지 향상되었다. 형광 현미경으로 관찰했을 때, apoptosis는 세포 배양 초기부터 중반까지 우세했고 빠른 교반 속도에서도 우세했다. 그러나 necrosis는 세포배양 말기와 동결된 세포가 해동 되었을 때 우세했다. HL-60 was cultivated to produce tPA (tissue-type plasminogen activator) and study the mechanism of cell death. Maximum cell density and tPA production were obtained as 5.27×10 exp (6) cells/ml and 324 ng/ml, respectively under perfusion cultivation. tPA production was enhanced to 420 ng/ml in adding 160 nM of phorbol ester. The cells were gradually differentiated to granulocytes rather than proliferation. By Fluorescent microscope, apoptosis was prevailed except the death phase and in high agitation speed, but necrosis was prevailed in thawed cells and during the latter periods of the cultivation. It was also proved that tPA was most produced in apoptosis. To obtain higher tPA productivity, the cells must be maintained in apoptosis, not necrosis phase when the cells were dying.

As the current stage of the fashion begins to follow the styles of the past, the study on the past costume is getting more important, and as the methodology of the study accurately approached study through the rehabilitation of the past costume is more needed than the simple rearrangement of the historical documents. By this methodology, this study can be positioned as a recreation activity. The results of the study are as follows. 1) Style : The general silhouetts is the late crinoline style which is the period from 1860s to just before bustle. The dress is one-piece composed of fitted bodice, and skirt which the front is flat, side and back is triangular shape to the skirts. 2) Color and Material : the main color is pale stone and the sub-color is ivory and blue. The dress is made of a silk surface and cotton back and partly satin and velvet. 3) Pattern and sewing : the dress is together sewing comnined with lining and fabric. The skirt is gored skirt, the number of patterns is plenty because of the plenty of width of skirt. The double piping has various effect not only to decorate but also to conceal the seam, support the silhouette. 4) Detail : The general detail is double piping which are repeatedly used to decorate stand collar, bands of sleeve, froint bodice and gored panel seam of skirt. And the fringe and velvet ribbon are used to decorate the dress. 5) Structural characteristics : The double piping, velvet ribbon and twilled cotton are used to emphasize structural characteristics of crinoline style. And the waistband which is backed with a webbing band to reinforce it is also the structural characteristics. Synthetically, the 1886~7 day dress has the characteristics of transitional stage in which the chararcteristics of the costume of 1860s and the remnants of the characteristics of the previous costume style, and shows the characteristics of day dress well in terms of the style, color and fabrics, pattern and sewing, detail, and structural characteristics.
