This study examined the condition of an educational discourse, relating the concept of creativity, culture, culture-centered, and critical thinking, to explore Culture-based Art Education(CBAE). In particular, art education practice was examined using interpretations of creativity and critical theory positions from the field of education. Discourse analysis was used as the research method to contextually situate and analyze the ways in which art education theory and practice of creativity and of critical studies encoded meanings. The study helped build an understanding that creativity was formed as a modernist discourse in the humanistic stance. In education, creativity became the fundamental concern for progressive educators who pursued innate ability of individuals. The way to enhance creative potential of students was to induce their motive, as was the same case in art education, while in artist training, free expression was its main method. In this way, as creativity was intimately connected with the concept of expression, in art education art making is the only course for enhancing creativity. However, because creative process cannot intelligently be regarded as logically distinct from the creative product, and creativity can only be said by product, it seems valid to think that creativity is the quality not to be achieved by teaching. Furthermore, its emphasis on art making resulted in unbalance of art making and art appreciation in art education. It was the late sixties when several alternatives for creative education were made their appearance. Critical studies in art adopted critical theory as its theoretical background has developed as an alternative of creative art education, when research and theory for creativity could not be adequate to deal with the problem of practice. Critical theory is a broad and diverse field of theory and practice drawing on aspects of the modernist perspective of the later Frankfurt School, feminism, Freirean pedagogy, postcolonial discourse as well as postmodernism to construct a practical approach to education. It is very this eclectic nature to provide the mosaic that need to experience cultures from different perspectives in a pluralistic society. Because one's personality is formed by multiple aspects of culture which is very complex and is made up of what we do and value, creativity cannot make part of educational discourse with the philosophy of culture centered. On the other hand, critical studies, as a school art program of critical theory, can perform the role of CBAE, because it would have to deal with the investigation of social and cultural issues form multiple personal, local, national, and global perspectives.

Korea's protected horticulture is rapidly increasing in scale due to various advantages such as year-round harvesting, labor savings through automation and shortened culture period, and greater income generation. This study was conducted to investigate the impact of protected horticulture on water quality. The results of this study are expected to provide basic data contributing to improvements towards sustainable agriculture and eco-friendly design of protected horticulture complex. The average T-N and T-P loads from vinyl greenhouses were 286.55± 143.98 mg/L and 59.14±13.77 mg/L, respectively and those from glass greenhouses 380.68 ± 150.41 mg/L and 61.85±20.72 mg/L. The annual discharge of wastewater derived from the monthly discharge from the horticulture greenhouses were estimated at 2597 ton/ha, with the annual phosphorus load amounting to 155.3 kg/ha. The average T-N and T-P loads in the tested greenhouse effluents were in excess of 8.3- and 13.5-fold the standards for the Korean wastewater plant effluent. The waste nutrient solution discharged from a protected horticulture complex can cause water contamination. Therefore, there is a need to conduct follow-up research using a water purification system or a trench method to develop a eco-friendly protected horticulture complex for sustainable agriculture.

This paper aims at a better understanding of the concept of korean separable syntactic atom, of which inner parts is separable in syntax, and at examining whether or not this concept can apply to derivatives, functional complex constructions, idiomatic expressions in korean. I defined a syntactic atom as a minimum unit which is drawn directly from lexicon and then is applied to syntactic rules. And I insist that so-called 'lexical island constraint' has some problems and that the syntactic rules can be applied to inner parts of syntactic atom, if the syntactic rules is irrelevant to new syntactic atom formation. The greater part of derivatives is non-separable syntactic atoms. But the likes of '반짝거리다', '죄송스럽다', '칭얼대다' are the separable syntactic atoms. The degree of separability of them is different in the insertion of korean particles or negative adverbs and the omission of root of sytactic atom. The derivatives of 'X-적', of which roots is regular nominal roots, permit the syntactic link between roots and the syntactic combination of the root and its argument. These kinds of derivatives is separable syntactic atoms. Also the derivatives of 'bracket paradox' and 'X-답-' derivatives is separable syntactic atoms. All functional complex constructions are not separable syntactic atoms. According to the degree of grammaticalization, inner parts of some are separable, some is non-separable. Separable functional complex constructions only permit the switching of endings or Josas but not application of other syntactic rules. All idiomatic expressions which are composed of two or more syntactic atoms are separable syntactic atoms. Some of them have so strong separability to allow the insertion of syntactic atom, adverb or adnominal modification and the noun in idiomatic expression to become the head of the relative clause. And some idiomatic expressions which have weak separability only permit interrogative's substitution or form change in fraction of idiomatic expressions.

본 연구는 디지털 애니메이션의 성공과 실패의 이유를 '몰입감'에서 찾고자 한다. 이를 위해서 비슷한 예산 규모의 두 작품, 즉 박스오피스 애니메이션 1위 <슈렉 2>와 172위 <화성은 엄마가 필요해>의 콘셉트와 스토리의 복합적인 비교를 통해 몰입감의 원인을 분석하였다. 복합적 연구 결과, 캐릭터 외면 콘셉트는 창의성과 대중성, 캐릭터 내면 콘셉트는 다양성과 유기성, 배경 콘셉트는 다양성과 일관성이 있는 콘셉트를 개발할수록 몰입감이 커진다. 또한 캐릭터 등장의 점층적 배치와 캐릭터 수의 양적 증가, 플롯 중심의 기승전결 변화가 고조될수록 몰입감이 증대되는 것으로 분석되었다. 결국 디지털 애니메이션의 몰입감은 창의성과 다양성, 대중성이 있는 시각적 콘셉트 개발과, 부분과 전체 스토리의 전략적인 기승전결 배치 및 강화로서 이를 융합시키는 것이 핵심이다.

From Jan. 1996 to Oct. 1997, 29 pigs with 40-70 days old showing dyspnea inappetite and polyserositis were collected and carried out necropsy, bacterial culture, histopathology, avidin biotin complex(ABC) stain, fluorescent antibody(FA) test, and electron microscopy. In the study, 4 strains from 3 pigs were isolated from meninges, pleura and synovial fluid and also were identified as Haemophilus parasuis serovar 5. Main histopathological lesions of 29 pigs with polyserositis were frequently composed of fibrinous peritonitis(27), pleurisy(22), interstitial pneumonia(21), fibrinous epicarditis(20), fibrinopurulent meningitis(8) and synovitis(4). By ABC stain, 11/29(37.9%) pigs with polyserositis were confirmed to have H parasuis serovar 5 in the cytoplasm of macrophages and neutrophils in cerebral meninges, epicardium, pleura surface of lung or serosa of spleen. ABC stain(20.8~40.0%) to detect H parasuis serovar 5 in tissues was more sensitive than bacterial culture(10.3%), but less sensitive than FA test(62.5%) using frozen tissues even though the result of 8 cases. By electron microscopy, a bacterium was also detected in the cytoplasm of macrophages in purulent exudate of cerebral meninges. Consequently, we confirmed that H parasuis serovar 5 has been involving to cause pigs with polyserositis and can be detected by FA and ABC stain as reliable diagnostic tools.

Developments in the recent media era has made distortion possible in accordance with changes in the fashion industry as new clothing, technologies, and fusions have become available. Nevertheless, previous studies of specific types of clothing, and their classification for the purpose of research are lacking. Thus, this study examines the development of the Pomme de look and the form of modern variant that appears in fashion clothing and new technologies, and largely examines the clothing case to clean it up. The method employed is leading research that examines the transformation about the concept of the Pomme de look with regard to the fashion about the type of look in the 2000s and onwards. This is organized in accordance with the analytical and physical characteristics, and the esthetic aspects of the results are as follows. The conclusions reached as follows are based on this; first, the physical characteristic manner when based on previous looks, the two-dimensional deformation for making clothes, if there was a simple way, now has more dimensions. Clothes are made in a complex manner and variations emerge. Second, esthetic characteristics strive for beauty while also displaying the modified and more complex manners of clothing that are emerging. Third, the fusion clothing with machines effects to physical and psychological changes through the details about how the sensor is worn. The enemy, the appearance of distortion, and clothing are emerging. This is expected to grow further based on the rapid development of new technologies and the transformation of Pomme de look and design will appear in more varied ways to create a convergence.

Changes in weed floras and development of plant resistance to herbicides seemed to be closely related with increased and repeated use of herbicides. Herbicide use increased from 5% of the total consumption of pesticide in 1950 to 45% in 1976 in world basis. About 200 herbicides have been introduced to agriculture so as to control about 206 weed species which have been recorded important to human beings. In Korea, there was about 351 times in increased use of herbicides from 1966 to 1982. Interspecific selection by herbicide is mainly responsible for changes in weed floras and resulted in varying tolerance or susceptibility to herbicides, together with the changes of agricultural practices. The present trend toward continuous cereal cultivation throughout world will lead to type of changes in weed floras favorable to therophyte which can survive under unfavorable conditions as seeds rather than the types of geophyte which can survive unfavorable seasons as buds placed below soil surface. However, geophyte such as Sagitaria pygmaea, and Scirpus jurtcoides, and Cyperus rotundus and Cynodon dactylon in temperate warm climate become severe paddy weeds, presumably because of the removal of annual weeds by herbicides. Since differential tolerance to 2,4-D was firstly reported in Agrostis stolofera, about 30 species of weeds in 18 genera are presently known to have developed resistance to triazine herbicides. Resistance of weed biotypes to triazine herbicide is not mainly due to limited absorption and translocation or to the difference in metabolism, but is the result of biochemical changes at the site of metabolic activity, such as a loss of herbicide affinity for triazine binding site in the photosystem II complex of the chloroplast membrane. Genetical study showed that plastid resistance to triazine was wholly inherited through cytoplasmic DNA in the case of Brassica campestris. Plant tissue culture method can be utilized as an alternate mean of herbicide screening and development of resistance variants to herbicides as suggested by Chaleff and Parsons. In this purpose, one should be certain that the primary target process is operational in cell culture. Further, there are a variety of obstacles in doing this type of research, particularly development of resistance source and it's regeneration because cultured cells and whole plants represent different developmental state.

To obtain an efficient natural lignocellulolytic complex enzyme, we screened an efficient lignocellulose-degrading composite microbial system (XDC-2) from composted agricultural and animal wastes amended soil following a long-term directed acclimation. Not only could the XDC-2 degrade natural lignocelluloses, but it could also secrete extracellular xylanase efficiently in liquid culture under static conditions at room temperature. The XDC-2 degraded rice straw by 60.3% after fermentation for 15 days. Hemicelluloses were decomposed effectively, whereas the extracellular xylanase activity was dominant with an activity of 8.357 U/ml on day 6 of the fermentation period. The extracellular crude enzyme noticeably hydrolyzed natural lignocelluloses. The optimum temperature and pH for the xylanase activity were $40^{\circ}C$ and 6.0. However, the xylanase was activated in a wide pH range of 3.0-10.0, and retained more than 80% of its activity at $25-35^{\circ}C$ and pH 5.0-8.0 after three days of incubation in liquid culture under static conditions. PCR-DGGE analysis of successive subcultures indicated that the XDC-2 was structurally stable over long-term restricted and directed cultivation. Analysis of the 168 rRNA gene clone library showed that the XDC-2 was mainly composed of mesophilic bacteria related to the genera Clostridium, Bacteroides, Alcaligenes, Pseudomonas, etc. Our results offer a new approach to exploring efficient lignocellulolytic enzymes by constructing a high-performance composite microbial system with synergistic complex enzymes.

게임 문화는 오프라인에서 온라인으로 중심축이 급격하게 바뀌었다. 급격한 변화는 온라인 게임의 발전으로 이어졌지만 게임 문화의 획일화를 불러 일으켰다. 이러한 게임 문화는 유저의 피로회복 및 스트레스 해소에 도움이 되지 못한 채 유저들에게 게임중독, 강박감, 편집증, 체력저하를 심어주고 있다. 그러나 몇 해 전부터 보드게임 붐이 일면서 보드게임카페를 통해 보드게임이 활발히 보급되었다. 보드게임을 통해 유저들은 과거의 추억과 사람사이의 유대감을 다시금 불러일으키게 되었고, 흥행 타이틀을 중심으로 저변이 확대되고 있다. 하지만 보드게임에 대한 유저들의 지식 부족과 한정된 타이틀 수, 부담스러운 타이틀 가격은 보드게임의 저변확대에 걸림돌이 되고 있다. 본 논문은 이 문제를 해결하기 위해 증강현실을 사용하여 보드게임과 온라인 게임의 장점을 융합하고 단점을 보완할 수 있는 증강현실 기반의 가이스터 게임을 제안한다. 이 게임은 보드게임 가이스터를 다양한 AR(Augmented Reality) 환경에서 구현하였다.

인삼(Panax ginseng C. A. Meyer) 캘러스로부터 분리한 원형질체를 배양하면서 배양시간에 따른 원형질체의 미세구조 변화와 원형질막 표면을 전자현미경으로 조사하였다. 3일 동안 배양된 원형질체에서는 조면소포체, 리보좀, 골기체, 미토콘드리아, 전색소체 등의 세포기관들의 수가 증가하였고 미소관도 관찰되었다. 골기체 주변에는 많은 골기소낭들이 형성되어 세포질 전반에 존재하였고, 이들 소낭들은 원형질막 바깥으로 돌출되어 돌기를 형성하기도 하였다. 소포체에서 유래된 액포속에는 액포의 함입에 의하여 골기소낭들이 들어 있는데, 이들 액포들은 융합에 의한 exocytosis로 원형질막 근처로 이동하여 원형질막과 융합한 다음, 세포벽 물질을 원형질막 바깥으로 방출하여 원형질막에 침적하였다. 전색소체는 많은 전분립을 함유하고 있었고, 미소관들은 원형질막 근처에서 막과 평형으로 배열하고 있었다. 배양된 원형질체의 표면에는 섬유소로 구성되어 있는 원섬유들이 서로 연결되어 있는 것이 관찰되었다.
