The Daetongsa temple is the earliest temple to be constructed during the era of the Three Kingdoms in ancient Korea. The main architect, purpose, and name of the temple have been confirmed through ancient literature and archeological materials carved in the Chinese letter, Daetong, excavated around Gongju. However, the location and range of the temple have remained elusive and were discussed in various studies. In this study, we examine the roof tiles obtained from the presumed site of the Daetongsa temple. The tiles were found to contain traces of red paint (red pigments) on their surface and analyzed using nondestructive techniques. The results imply that roof tiles were made using clay tablets and wooden cylinders, with latticed cloth in between. Additionally, some wooden cylinders appeared to comprise numerous wooden plates tied together by strings. The clay tablets used to make the roof tiles were produced from the source clay via the sorting process. The traces of red paint on the surface of the roof tiles were verified to be traditional pigments used for painting wooden buildings. These pigments were extracted from red ocher or red clay (Seokganju), mainly consisting of iron oxide. In the literature, the location of provenance sites for Seokganju is estimated to be far from Gongju. However, the materials for extracting the red pigments were relatively easy to source because most rocks comprised iron oxides. Therefore, it is necessary to discuss the provenance of the red pigments around the presumed site of Daetongsa.

Wine consumers desire to drink a high quality wine. For producing high quality wine, high quality soil is required. Conventionally, soil quality is assessed qualitatively. Using traditional laboratory methods, quantitative data can be obtained for management purpose, but it is time consuming and expensive. Therefore, new technology aims to address these limitations, namely portable X-Ray fluorescence spectrometers (pXRF). This instrument can be used directly in the field, requires no soil sample preparations, and can simultaneously measure a wide range of elements qualitatively that are useful for pedological studies. The chemical composition (Ca, Fe, Ti and Zr) of soils at Tallavera Grove vineyard in New South Wales, Australia, was studied using a pXRF. The analysis of the soil's elemental concentration (i.e. Ca and Fe) using pXRF supports management decisions. Measuring the soil's Ca concentration can be used to identify Ca-rich parent materials (limestone). The limestone indicates good soil conditions for vine production. Fe content was used to identify areas of texture-contrast soils or soil with accumulation of clays in the B horizon. In addition, a soil weathering index was calculated using elemental concentrations (i.e. Ti and Zr) to explore the history of soil formation for making decision of management. This index showed that the soil in the vineyard was affected by two processes: the deposition of materials from elsewhere (Aeolian transport or soil erosion) and mixing of materials from upslope.

This study is an investigation that explication of the reading method of transcription marking, and explains what it means and where to use transcription marking of architectural vocabulary. focusing on timber class vocabulary from on SeoGwolYeongGeonDoGamUiGwe(${\ulcorner}$西闕營建都監儀軌(1831)${\lrcorner}$). This study is reviewed sequentially classifying items according to timber class, stone class, iron class architectural vocabulary. This treatise, named 'Architectural Vocabulary Study (1)', is mainly focused on making out a transcription marking of timber class vocabulary on the documents. But, because of the properties of the UiGwe(儀軌), there are some different expressions used for the same vocabulary. Therefore, the different expressions are referenced according to vocabulary used from the 17th century to the 20c century. This study lists timber class architectural vocabulary of transcription marking on SeoGwolYeongGeonDoGamUiGwe(${\ulcorner}$西闕營建都監儀軌(1831)$\lrcorner$). This study also explicates and explains the meaning of them. In advance, this study compares them with the vocabulary of national language in the middle ages and modern times. If we could explicate the transcription marking of the documents as it is, we can't only recover plenty of vocabulary related with characteristic architecture in the age of later Chosun Dynasty, but also correct wrongly used vocabulary nowadays. With the results, we can standardize and adjust vocabulary use of Korean traditional architecture. In advance, we can correct errors of spelling and mistaken explanation in the Korean Encyclopedia.

Debates on what is the first skyscraper have been ongoing from time to time since the construction of the Home Insurance Building in Chicago in 1885, which is generally recognized as the first built skyscraper. This paper attempts to verify this assertion through a detailed investigation after identifying the criteria that characterize a skyscraper. By considering and examining several competing buildings for the title of "first skyscraper" in terms of their levels of satisfying these criteria, the paper reconfirms that the Home Insurance Building in Chicago indeed qualifies as the first skyscraper and is the harbinger of future skyscrapers. By introducing technological and associated architectural innovations in this pioneering building, its designer William Le Baron Jenney paved the way for the construction of future skyscrapers. In traditional construction, heavy masonry walls especially at lower levels did not allow large window openings in exterior walls that would permit ample daylight. For the Home Insurance Building, originally built with 10 stories, Jenney created a metal-framed skeletal structure that carried the building's loads, making the building lighter and allowed for large windows permitting ample natural light to the building's interior. The exterior iron columns were encased in relatively small masonry piers mainly for fireproofing, weather-protection and façade aesthetics. Relying on the structural framing on the building's perimeter, the exterior masonry thus turned into a rudimentary "curtain wall" system, heralding the use of curtain wall construction in future skyscrapers. This building's innovative structural system led to what is known as the "Chicago Skeleton," and eventually produced remarkable skyscrapers all over the world.

This study is to examine the remained basis and the locational characteristics of manufacturing in Chonnam region. First, the locational characteristics of manufacturing in the peripheral region examined through theoretical discussions about manufacturing location. And the locational characteristics of the small and medium firms and large firms be studied as to understand the precedent characteristics of Chonnam region. Chonnam region have the precedent characteristics that the regional capital is not accumulated as Japen exploit agricultural products at a colonial period. And SOC, industry and technology are not developed as geographically Chonnam lesion turn aside the economics axis of Korea-Japen-America within a period of industrialization. Manufacturing firms have beer make up the traditional indigenous firms which base on local market, agriculture and marine products in Chonnam lesion. The characteristics of these firms mainly are food & drink, nonmetal industry that is composed of the small and medium sized firms. The industrial structure is changing to machinery, chemistry, electronics industry from food & drink, nonmetal industry. But these industry is making the simple products. In Chonnam region, these change of industrial structure was expanding to the inland or coast region from the neighhoring region of Kwangju metropolitan. The blanch factories of large enterprises that located in Chonnam region are not connected with small and medium sized firms. The small and medium sized firms are not developed. Because these large enterprises are the iron and steel industry or chemistry industry. So the large-manufacturing firms have characteristics of the capital intensive industry, and make up the monopolistic industrial space of fordist blanch factories.

Human hunted and picked to survive and a vessel was made naturally to store something being hunted and picket, which was a great invention. In modern times, society changed and development of science gave us convenience in making a vessel and various kinds of store instruments which was made of pure natural material, of new stuff, such as plastic and iron. but human became to be inclined to regress into nature because of problems of environment. We can say that the representative trend is well-being, after all this is a symptom to return to life being persued by predecessors before the science civilization was developed. Ancestors have lived with nature, adapted themselves to it. For examples they have built the house which became to be a part of nature and just like it, and studied a method of storing food to eat for four seasons, then displayed a storagehouse and storage containers everywhere of the house. Now Korean has the custody of kimchi in refrigerator at every house, but our forefathers controled a timing to eat food with studying a method of storage to put to use nature. With hot wind of well-being, Korean food is becoming to be globalized, according to this, concern about the wisdom of progenitors is growing more and more. It's an example that the world shows concern seriously about the pottery, which have stored kimchi for a long time fleshly, in globalization of kimchi. This study have three purposes, the first. checking documents about the development history of pottery which is a kind of ceramic, and then the second, through an scientific experiment, with studying characteristic of pottery being built by the wisdom of ancestors, informing the merit of pottery and necessity to the world, and futhermore, the third, working up the development of close environmental vessels putting to use the characteristic of pottery.
