        徐有榘의 『林園經濟志』에 실려 있는 「팔도 물산」에 대한 연구

        서종태(Seo Jong Tae) 서강대학교 인문과학연구소 2018 서강인문논총 Vol.0 No.53

        서유구의 『임원경제지』의 마지막 편인 「예규지」에 「팔도 물산」이 실려 있다. 이 「팔도 물산」은 총론과 각 도의 토산물 자료로 구성되어 있다. 팔도의 토산물을 도별로 총괄해 서술한 총론은 이익의 『성호사설』에 실려 있는 「생재(生財)」의 일부를 인용한 것으로, 그 말미에 『성호사설』이 인용서로 기록되어 있다. 그러므로 총론은 서유구의 저술이 아니라 편찬물이다. 고을들의 토산물을 도별로 구분하여 서술한 각 도의 토산물 자료의 말미에는 『여지도서』가 인용서로 기재되어 있다. 그러나 「팔도 물산」의 토산물 중 『여지도서』의 토산물과 중복되는 비율은 66.5%이고, 새로 추가된 비율은 34.0%이다. 이로써 보아 「팔도 물산」의 토산물은 『여지도서』의 토산물과 크게 다르다는 것을 알 수 있다. 그러므로 「팔도 물산」의 토산물 자료는 서유구가 『여지도서』의 토산물을 참고하여 새롭게 저술한 것이다. 서유구가 「팔도 물산」의 토산물 자료를 저술한 목적은 지방의 장시를 중심으로 상업 활동에 종사하는 사대부에게 도움을 주기 위한 것이었다. 이 토산물 자료에는 19세기 초엽 당시 지방의 장시에서 유통되던 총 330개 고을의 주요 토산물이 수록되어 있다. “Yegyu-Ji(倪圭志)”, the last chapter of The Encyclopedia of Rural Life(林園經濟志) written by Seo Yoo-gu(徐有榘), includes the section ‘Paldo-Moolsan'(八道物産: Products of the Whole Nation). ‘Paldo-Moolsan' consists of the General Outline and information on local products of 8 Provinces of the Joseon Dynasty. The General Outline that summarizes the local products of 8 Provinces cites part of “Saeng-Jae”(生財: Increasing Wealth), a chapter of Seongho-Saseol(星湖僿說) authored by Yi Ik(李瀷). At the end of the General Outline Seongho-Saseol is cited as the source of information. The General Outline, therefore, is not a section originally written by Seo Yoo-goo, but a compilation. Yeo-Ji-Do-Seo(輿地圖書) is cited as the source at the end of information on the local products of each province, which describes the products of villages in different provinces. However, of the local products listed in ‘Paldo-Moolsan', 66.0% overlap with those listed in Yeo-Ji-Do-Seo; and 34% are new additions. This confirms that the local products described in ‘Paldo-Moolsan' are quite different from the products described in Yeo-Ji-Do-Seo. Therefore, the local products data recorded in ‘Paldo-Moolsan' is a new contribution written by Seo Yoo-goo, after consulting the local products recorded in Yeo-Ji-Do-Seo. Seo Yoo-goo compiled the data of local products in ‘Paldo-Moolsan' for the purpose of helping the gentry classes who were engaged in commercial activities around regional markets. The local products data lists the main products of 330 villages throughout the country that were being distributed in the local markets during the early of the 19th century.

        고려 후기 얼자(孽子)의 지위 향상과 그 역사적 배경

        이종서(Lee, Jong-seo) 한국역사연구회 2015 역사와 현실 Vol.- No.97

        Examined in this article are the Seo'eol figures of the Goryeo period, who were also the former version of the Joseon Seo'eol figures. They were called as a whole as ‘Seo/Eol' in Joseon, but in Goryeo there was a strict distinction between ‘Seo(庶)' and ‘Eol(孼).' In the early half of the Goryeo period, the latter(“Eolja” figures) were not allowed to be appointed to governmental positions, and the former(“Seoja” figures) were in some cases restricted from applying for the dynastic competitive examination and was not allowed to rise above certain level of posts inside the government. But coming into the second half of the Goryeo period, not only cases of Seoja figures but also those of Eolja figures, in which they were able to apply for the dynastic exam and rise to the highest level of posts inside the government, started to emerge. We can see such changes inside the royal family as well, as the Eolja sons of the king, who were formerly without any right to claim succession to the throne and were forced to become Buddhist priests, were now entitled to become governmental officials or receive honorary entitlements. We can see that from the case of King Gongmin-wang's Eolja son Wang Wu, who was enthroned in 1374 as Gongmin-wang's successor. Elevation in the Eolja figures' status in the second half of the Goryeo period was enabled in the wake of the Yuan imperial government's strong and steady influences and interventions into Goryeo internal affairs. At first, the Eolja figures mounted individual attempts and efforts to use the situation to their advantage. And when they grew sufficiently accustomed to the Yuan imperial order, their acknowledgement of the Yuan order, its law codes which were not without Chinese elements, and the Chinese nature of such behavioral protocols, all enabled them to accept the notion that Eolja figures deserve new chances and especially avenues of career advancement which were not available for them before. The Yuan law code which dictated and defined the status and rights of the ‘Seo(庶)' figures literally granted the Seo and Eol figures in Goryeo the right to claim fiscal properties and career opportunities. The Goryeo leadership, including all the Confucian intellectuals, positively responded to the situation and recognized the Eolja figures' political and social rights. Their status elevation did not involve anything abnormal or illegal, and even after Yuan lost its influences, they maintained such elevated status, which explain how the social status of the Seo/Eol figures in the early half of the Joseon period came to be established.

      • Jasmonic acid carboxyl methyltransferase : a key enzyme for jasmonate-regulated plant responses

        Seo,,Hak,Soo,Song,,Jong,Tae,Cheong,,Jong-Joo,Lee,,Jong,Seob,Choi,,Yang,Do 이화여자대학교 세포신호전달연구센터 2001 고사리 세포신호전달 심포지움 Vol. No.3

        Methyl jasmonate is a plant volatile that acts as an important cellular regulator mediating diverse developmental processes and defense responses. We have cloned the novel gene JMT encoding a S-adenosyl-L-methionine: jasmonic acid carboxyl methyltransferase from Arabidopsis thaliana. Recombinant JMT protein expressed in E. coli catalyzed the formation of methly jasmonate from jasmonic acid with Km value of 38.5 mM. JMT RNA was not detected in young seedlings but was detected in rosettes, cauline leaves and developing flowers. In addition, expression of the gene was induced both locally and systemically by wounding or methyl jasmonate treatment. This result suggests that JMT can perceive and respond to local and systemic signals generated by external stimuli, and that the signals may include methyl jasmonate itself. Transgenic Arabidopsis overexpressing JMT had a 3-fold elevated level of endogenous methyl jasmonate without altering jasmonic acid content. The transgenic plants exhibited constitutive expression of jasmonate-responsive genes including VSP and PDF1.2. Furthermore, the transgenic plants showed enhanced level of resistance against the virulent fungus Botrytis cinerea. Thus, our data suggest that the jasmonic acid carboxyl methyltransferase is a key enzyme for jasmonate-regulated plant responses. Activation of JMT expression leads to production of methyl jasmonate that could act as an intracellular regulator, a diffusible intercellular signal transducer, and an airborne signal mediating intra- and inter-plant communications.

        Some Common Fixed Point Theorems using Compatible Maps in Intuitionistic Fuzzy Metric Space

        Jong,Seo,Park 한국지능시스템학회 2011 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.11 No.2

        Kaneko et al.[4] etc many authors extended with multi-valued maps for the notion of compatible maps in complete metric space. Recently, O'Regan et al.[5] presented fixed point and homotopy results for compatible single-valued maps on complete metric spaces. In this paper, we will establish some common fixed point theorems using compatible maps in intuitionistic fuzzy metric space.

        Nitrogen Use and Yield of Silage Corn as Affected by Hairy Vetch (Vicia villosa Roth) Soil-incorporated at Different Time in Spring

        Jong-Ho,Seo,Ho-Jin,Lee,Il-Bong,Hur,Si-Ju,Kim,Chung-Guk,Kim,Hyeon-Suk,Jo,Jung-Sam,Lee 韓國作物學會 2000 Korean journal of crop science Vol.45 No.4

        Winter green manure crops including legume increase grain yield of subsequent crop and substitute N fertilizer requirement with organic-No Hairy vetch grows vigorously and can provide N-rich green manure for corn with its soil incorporation after wintering. But, grain yield of corn as succeeding crop would be reduced if its planting time is delayed until late spring. This experiment was carried out to find the proper incorporation time of hairy vetch green manure and planting time of subsequent corn in cropping system with winter hairy vetch(green manure)-summer corn. Hairy vetch was incorporated into soil at a ten-day interval between April 10 and May 10 and corn was planted at 5 days after each hairy vetch incorporation. Soil nitrate concentration on April 10 and 20 in hairy vetch plot was slightly lower than that at winter fallow. Above-ground dry matter and organic-N of hairy vetch increased linearly with delayed hairy vetch incorporation time from April 10 to May 10. Average dry matter and organic-N produced by hairy vetch were 5.7 ton/ha and 248 kgN/ha, respectively. Corn growth and yield decreased as delayed corn planting time after May in spite of increasing dry matter and N-yield of hairy vetch. Nitrogen concentration of corn grain, stalk and whole plant at harvest were the highest in May 5 planting, but total N-uptake of May 5 planting were not different from that of April 25 planting because of lower grain yield. It was concluded that the proper incorporation time of hairy vetch and corn planting time were April 20 and April 25, respectively, because grain yield was the highest and corn could use hairy vetch-N effectively to produce dry matter.

        Use of Hairy Vetch Green Manure as Nitrogen Fertilizer for Corn Production

        Seo,,Jong-ho,Lee,,Ho-jin,Hur,,Il-bong,Kim,,Si-ju,Kim,,Chung-kuk,Jo,,Hyeon-suk The Korean Society of Crop Science 2000 Korean journal of crop science Vol.45 No.5

        Hairy vetch (Vicia villosa Roth) winter annual is very effective on reducing chemical nitrogen fertilizer for subsequent com by fixed organic green manure nitrogen fixed during hairy vetch growth. In this experiment, hairy vetch produced above-ground dry matter of 5 ton/ha, nitrogen yield 200 kgN/ha, at com planting on the average during 1997 and 1998. Changes in com yield and nitrogen uptake for two years were investigated after application of nitrogen fertilizer 0, 60, 120, 180, 240 kgN/ha on plot of winter fallow and hairy vetch green manure, respectively. Nitrogen status such as ear-leaf N%, SPAD value at silk and dough stage, and com yield decreased in proportion to reduction of nitrogen fertilizer at winter fallow, but nitrogen status and yield of com were not different among nitrogen fertilizer rate at hairy vetch green manure. Com yield (total dry matter) at 0 kgN/ha plot of hairy vetch was 22, 20 ton/ha in 1997, 1998, respectively and com could produce more dry matter 9, 13 ton/ha by hairy vetch green manure compared with winter fallow under the condition of no nitrogen fertilizer in 1997, 1998, respectively. Com yield (total dry matter) at 60kgN/ha of hairy vetch green manure was higher than that of high N fertilizer rate such as 180, 240 kgN/ha of winter fallow. Nitrogen uptake of com at plot of hairy vetch-no nitrogen fertilizer slightly decreased than at plot of hairy vetch - nitrogen fertilizer, but com absorbed more nitrogen of 141, 159 kgN/ha by hairy vetch green manure compared with winter fallow under no nitrogen fertilizer condition in 1997, 1998, respectively. Nitrogen fertilizer reduction for com by hairy vetch green manure was 149, 161kgN/ha in 1997, 1998, respectively. Still more, com could absorb more soil nitrogen by nitrogen fertilizer 60kgN/ha of hairy vetch green manure than by high nitrogen fertilizer such as 180, 240 kgN/ha at winter fallow. It is concluded that nitrogen fertilizer for corn could be reduced by winter cultivation and soil incorporation of hairy vetch at com planting.
