Paekche black potteries are earthenwares begun to be produced at the beginning of Paekche Dynasty, around 3-century. They have typical Paekche style. Representative Paekche earthenwares are burnished black pottery, long oval shaped pots and shoulder pots. Among these, burnished black potteries are limited to Paekche in the occurrence site and age. Their numbers are a few. To reproduce black pottery, their compositions were analyzed. As a result of X-Ray analysis, quarts, feldspar, illite, muscovite, and anorthite were found on their surfaces and imsides spinel and vermiculite were found on their surfaces. Since same constituent minerals were found on surfaces and their insides, special other materials were not added to make surface black. With the showing vermiculite, they were made higher than $800^{\circ}C$. As a result of analysis, fine grained clay bad been influenced by the black smoke. Its luster was appeared by polishing with a big flat wooden spoon. The black color was made of smoking when the hot pot taken off from burning oven was covered with the wet pine leaves.

The plain coarse pottery from the Unjeonri Bronze Age relic sites in the Cheonan, Korea were studied on the basis of clay mineralogy, geochemistry and archaegeological interpretations. For the research, the potteries are utilized at the analysis for 6 pieces of plain coarse potteries. Color of the these potteries are mainly light brown, partly shows the yellowish brown to reddish brown. The interior, surface and inside of the pottery appear as different colors in any cases. Original source materials making the Unjeonri potteries are used of mainly sandy clay soil with extreme coarse grained irregularly quartz and feldspar. The magnetic susceptibility of the Unjeonri pottery range from 0.20 to 1.20. And the Unjeonri soil's magnetic susceptibility agree almost with 0.20 to 1.30. In the same magnetization of soil and pottery, the results revealed that the Unjeonri soil and low material of pottery are same produced by identical source materials. The Unjeonri potteries and soil are very similar patterns with all characteristics of soil mineralogy, geochemical evolution trend. The result seems to be same relationships between the behavior and enrichment patterns on the basis of a compatible and a incompatible elements. Consequently, the Unjeonri potteries suggest that made the soil to be distributed in the circumstance of the relic sites as the raw material are high in a greater part. In the Unjeonri soil, the kaolinite is common occurred minerals. However, in the Unjeonri pottery, the kaolinite was not detected in all broken pieces. The kaolinite was presumed to destroy crystal structure during the firing processes of over $550^{\circ}C$. The quartz is phase transition from ${\alpha}$-quartz to ${\beta}$-quartz at $573^{\circ}C$, but the Unjeonri pottery did not investigated any phase transition evidences of quartz. The chorite was detected within the mostly potteries and soils. As the results, the Unjeonri potteries can be interpreted by not experiencing a firing temperature over $800^{\circ}C$. The colloidal and cementing materials between the quartz and low materials during the heating did not exist in the internal part of the potteries. An any secondary compounds by heating does not appear within the crack to happen during the dry of the pottery. The hyphae group are kept as it is with the root tissue of an organic matters to live in the swampy land. In the syntheses of all results, the general firing condition to bake and make the Unjeonri pottery is presumed from $550^{\circ}C$ to $800^{\circ}C$. However, the firing condition making the Unjeonri pottery can be different firing temperature partially in one pottery. Even, the some part of the pottery does not take a direct influence on the fire.

Niobium oxide (Nb₂O5) has a strong chemical coherence and good electrical conductivity. Therefore, this material is helpful to enhance the performance of the dye sensitized solar cells (DSC) by improving the electron mobility. In this study, Nb₂O5 was mixed with TiO₂ and this compound was applied to the DSC to improve its performance. As a result, the current density of the DSC using the Nb₂O5-TiO₂ compound on the photoelectrode was increased, because the internal resistance concerned to the electron transfer in the photoelectrode of DSC was decreased. However, large amount of the Nb₂O5 induces the decrease of the efficiency of the DSC because the surface area to attach dye molecules is decreased due to the large particle of Nb₂O5. Therefore, it is important to optimize the mixture ratio of the Nb₂O5-TiO₂ compound for maximizing the performance of the DSC. Finally, the most optimum performance of the DSC was shown in case of the Nb₂O5 concentration of 10 wt% of the Nb₂O5-TiO₂ compound.

Considering the depositional environment and geochemical behaviors of metals, a total of 12 surface sediments were sampled along two sections in the tidal flats of Cheonggye bay. The mean size of sediments showed between -0.82Ø to 4.97Ø and 1.65Ø to 7.43Ø in Topmeori and Meoguri tidal flats and the sediments were sorted in 1.79Ø to 4.66Ø and 0.77Ø to 2.44Ø in above flats, respectively. The Topmeori flats are composed of msG, gM, gmS, zS and sM, while the Meoguri flats contained (g)S, zS, sZ, Z and M in facies. From the geochemical investigations of the sediments, major and minor elements of the sediments mostly showed the increasing trends toward open sea in contents. The elementary contents might be controlled by clay minerals produced from surrounding rocks, carbonate shell fragments, coarse feldspathic portions of the sediments related with circumferential geology and so forth. In addition, enrichment factors (EF) of the sediments were investigated. K, Mn, Ba, Li, Zn and Pb were enriched in the sediments. Of them, Li, Zn and Pb were generally related to organic contamination. Thus, administrations on above areas are needed in contamination.

근대 중국의 唐詩 읽기와 정전으로서의 唐詩

崔晳元(Seok-Won Choi) 중국어문논역학회 2022 中國語文論譯叢刊 Vol.- No.50

주지하듯이 전통 시기 중국 사회를 지탱하던 ‘文’에 대한 기존의 질서는 근대로 접어들면서 균열과 붕괴를 경험하였다. 본고는 이렇듯 문학에 대한 새로운 인식이 배태되었던 중국의 ‘근대’ 그 중에서도 20세기 초 혼란과 변화를 경험한 시공간을 통해 중국 전통 사대부 문학의 대표라고 할 수 있는 唐詩에 대한 시각과 인식에 대한 고찰을 진행하고자 한다. 일찍이 ‘정전’이라 함은 텍스트가 처한 사회문화적 맥락 속에서 그 지위가 획득되거나 상실되는 과정을 포함한다고 할 수 있는바, 본고는 20세기 전반기 唐詩와 관련한 전반적인 문헌의 대략을 살펴봄과 함께 20세기라는 새로운 시대적 맥락 속에서 唐詩는 어떻게 읽혀지고 있었는가를 고찰하고자 하였다. 함께 담론화 그리고 계몽을 목적으로 한 근대 교육의 제도 속에서 새롭게 위치지워졌던 唐詩의 모습을 확인함으로써 고전이 아닌 정전으로서의 唐詩 그 일면을 고찰하고 이에 내재된 문학적, 문화적 의미 규명에 다가가는 데 그 목적을 두었다. As is well known, as we entered the modern period, the perception of “Wen” in the traditional Chinese period experienced a crack. This study intends to examine the perspective and perception of T’ang poetry, which can be said to be the representative of intellectual literature among traditional Chinese literature, through the ‘modern’ in China, where a new perception of literature was born. ‘Canon’ can be said to include the process of acquiring or losing its status in the cultural context in which the text is placed. This paper intends to examine the outlines of the publication of anthology related to T’ang poetry in the early 20th century and how it was read in the context of the 20th century. In addition, the purpose of this study was to examine T’ang poetry as a canon by confirming the appearance of the time in the literary discourse and system of modern education, and to approach the identification of the literary and cultural meanings inherent in it.

논문(論文) : 김성탄(金聖歎) 두시(杜詩) 비평(批評) 양상 고찰

최석원 ( Seok Won Choi ) 중국어문연구회 2013 中國語文論叢 Vol.0 No.60

金聖歎在中國文學史上的主要貢獻是雙中: 第一, 他是最有影響的通俗文學提倡者之一; 第二, 他開創了中國式``細讀``的文學批評方法。因此, 最近對金聖歎的文學成果硏究是注重于其通俗文學上的成果以及貢獻。金聖歎的``六才子書``不僅僅包括如≪莊子≫、≪離騷≫、≪史記≫等的正統文學作品, 也有如≪杜詩解≫的詩歌批評書。本文以≪杜詩解≫爲硏究對象進行分析金聖歎的杜詩批評方法和杜詩解釋。其實, 金聖歎흔愛好杜甫的詩歌作品, 因此他在實際詩歌創作過程中采用了與杜詩同樣的試題或風格等, 可見在≪沈吟樓詩選≫中"擬杜少陵"、"擬杜"、"借杜"等作品。而且在≪淸詩記事初編≫和≪淸詩別裁集≫中說明了金聖歎的作品和杜甫的風格흔相似的。雖然金聖歎尊重杜詩, 但他的≪杜詩解≫不能受到흔多文人的歡迎。特別在≪四庫全書總目提要≫中批判金聖歎用分解來分析律詩的方式。本稿擺脫如此的評價, 進行分析金聖歎對杜詩的批評中所見的文學觀。金聖歎的≪杜詩解≫提出了對杜詩的讀法, 第一是詩題與作品內容之間的關係。具有흔長詩題的作品中他按照詩題與內容之間的關係來分析作品。第二是用分解的方法來分析杜詩。他在≪北征≫批評時, 先分開三十五段的解, 之後分析各個分段的內容而且說明每個段之間的關係。如此的杜詩分析方法也可見仇兆鰲的≪杜詩詳注≫和浦起龍的≪讀杜心解≫等淸代主要杜詩注釋。由此可見金聖歎用詩題、分解的方法影響到了後代杜詩解釋者。更重要的是, 金聖歎的評點內容中可見他的文學批評觀點。他按照"斷章取義"的中國傳統文學批評態度再構成了杜詩的內容。金聖歎的批評觀點受明末淸初的文學潮流, 當時文人肯定了讀者的價値。換言之, 他們重視了對文本的獨特、個別的解釋。雖然金聖歎對杜詩解釋上的獨特性受到尖銳批判, 但從讀者的價値肯定和解釋的多樣性的角度來看, 他的杜詩解釋對現在杜詩讀者也흔有意義。
