To analyze dialy meal of royal meal, studied Jook Soora Sang (Rice Gruel), Mieum Sang (Thin Gruel) and Bankwa Sang, Soora Sang in Hyun Neung Won were on record Wonheng Ulmyo Jungri Euigwae (1795). Historic book "Jungri Euigwae" described the king's visit to his father's royal tomb "Hyun Neung Won", during the domain of Cheung Jo, the 22nd king of Choson Dynasty. The results obtained from this study are as follows. Rice Gruel (Jook Soora Sang), taken before breakfast, was arranged the same as the Soora Sang. The table for thin gruel (Mieum) was arranged in three kinds of sets; one for thin gruel, the others for stewed meat (Goem) and sugared fruit (Jeong Kwa). The diet seems to have been quit scientific and restorative. Bankwa Sang and Soora Sang in Hyun Neung Won was arranged the same as the other Bankwa Sang and Soora Sang. Therefore setting the table of royal meal had a rule.

정성일의 <오아시스> 비판에 투영된 관점의 가능성과 한계 - 정성일 영화비평에 대한 일고찰 -

박우성 ( Park Woo-sung ),정수완 ( Jung Su-wan ) 국제어문학회 2015 국제어문 Vol.0 No.67

본 연구는 영화비평가 정성일이 <오아시스>(이창동, 2002)에 대해서 쓴 비평문「판타지, 기만적인 환영술」을 비판적으로 분석한다. 그간 한국영화계에서 영화비평은 독립적인 분과로 논의되지 못했다. 산적하는 영화들 안에서 영화적 가치를 발굴해 정리하고 새로운 영화 언어를 대중 언어로 번역하는 것이 영화비평의 역할이라 했을 때 이는 문제가 있다. 영화비평에 대한 그간의 접근은 한국영화사의 맥락에서 특정 영화비평집단을 세대론적으로 조망하거나 특정 개인의 비평 세계를 전기적 관점에서 서술한 것에 머문 한계가 있다. 정성일은 1990년대 한국영화비평의 전성기를 주도했던 한국의 대표적인 영화비평가이다. 호불호가 갈리지만 그의 글은 대중들 사이에서 영화비평이라는 개념이 성립되는 과정에 주요한 이미지를 제공했다. 특히 본 연구가 다루는 정성일의<오아시스> 비판은 논쟁 참여를 전제해 작성된 덕분에 비평담론 자체가 중심에 서있고 무엇보다 정성일의 영화에 대한 태도가 여타의 글에 비해 명확하게 드러나는 특징이 있다. 더구나 그 논쟁은 영화의 윤리, 완성도, 자의식 등을 두고 벌어진 영화비평계 내부의 마지막 논쟁이라는 영화비평사적 의의도 있다. 나아가 영화 한편에 대한 긴 글이기 때문에 한국의 대표적 비평가가 영화를 비평하는 구체적 실천 양상이 현장감 있게 녹아 있기도 하다. 영화를 종교처럼 대한다는 비판이 존재하지만 정성일 영화비평의 경쟁력은 숏의 배치, 장르 문법, 카메라 시선과 같은 영화의 자의식을 정밀하게 분석하는 것에서 나온다. 영화란 무엇인가와 같은 근본적인 질문에 기반을 둔 이런 태도는 영화를 여타의 학문에 종속시킨 종래의 비평 태도와 차별되며 영화를 진지하게 바라보는 태도를 대중화시킨 의의가 있다. 하지만 그것만큼의 오류도 발견된다. <오아시스>를 비판할 때 투영되는 정성일의 관점의 가능성과 한계를 구체적으로 밝힘으로써 한국영화비평의 전성기를 주도했던 한 영화비평가의 개성적 세계관을 비판적으로 조망하는 것이 본 연구의 목적이다. 독립적인 분과로 인식되기는커녕 죽음까지 운운되는 영화비평의 위기 시대에 한국의 대표적 영화비평가의 세계관이 상징적으로 녹아 있는 글을 정밀하게 분석하는 것은 그것 자체로 의미 있다. This study analyzes the critique “Fantasy, deceptive hallucination” which sung-il jung wrote about < Oasis >(Changdong Lee 2002). Film critique has not been recognized and discussed as an independent field in the Korean film industry so far. It can be problematic if the role of film criticism is to get the cinematic values arranged among the pile of films and to translate new cinematographic language into the public language. The approach to the film critique to this point has limitation that in the context of Korean film industry, it viewed certain group of film critics in the perspective of theory of generation and it described certain person`s world of criticism in a biographical way. sung-il Jung is one of the representative film critics in Korea who lead the golden age of Korean film criticism in the 1990s. His writings provided important image in the process of establishing the concept of film critique among the public, even though they are controversial. The Jung`s criticisms this study exclusively deals with are based on the premise of argumentative participation, so the discourse is central and fundamental, and it brings out the cinematic view of Jung precisely compared to the other writings and articles, which is the advantages of this study. Moreover, the argument has significance in the field of film criticism for being the last dispute inside the field of film critique over the morals, degree of completion, and the consciousness of identity. Above and beyond, because this paper is a long writing about a movie, it contains detailed and vivid practical aspect which the representative critic of Korea criticizes the movie. Although there are criticisms of discussing movies like a form of religion, sung-il Jung`s film critique is competitive for detailed and precise analyze of films` sense of identity such as plot of shots, code of genre, and the eyes of cameras. This attitude based on the fundamental questions such as what is film is considered significant for popularizing and promoting earnest attitude toward movies, and is differentiated with the traditional attitudes of criticism which are to subordinate films in the other fields of study. However, due to being so, some errors are discovered. The purpose of this study is to critically outlook a distinctive world view of a film critic who enjoyed the film critique`s prime by concretely describing its possibilities and limitations through revealing Jung`s point of view which is his prerequisite for watching movies. The work of precise analyzing of one of the Korean representative film critics` writings which contains symbolic world view is significant and meaningful by itself in the time of the film criticisms` crisis when the idea of the demise of film criticism is being mentioned, let alone its separation as the independent field.

Extension of Lance Life by Change of Height of Lances in the Smelting Furnace of Mitsubishi Process

Sung‑Mi Lim,Soo‑Sang Park,Kyung‑Woo Yi 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.10

A Mitsubishi process, which pertains to continuous Cu production, involves a smelting furnace, cleaning furnace, and convertingfurnace connected in series. One of the main issues pertaining to the smelting furnace is the frequent interruption ofoperations required to allow the inspection and replacement of lances, because lances are frequently fractured. The presentstudy was aimed at modifying the operating conditions of the smelting furnace to suppress lance fractures. A numericalmodel was developed to simulate the transport phenomena in the furnace, including multi-phase behaviors. The simulationresults showed that the lances were exposed to a severely erosive atmosphere with high temperatures. Further calculationindicated that raising the positions of the lances could lower the temperature of the lances, and reducing the occurrence ofsplashed melt, which contains erosive sulfides. The smelting furnace was operated under the conditions of the raised lanceheight and attentively monitored for several months. It was confirmed that by implementing such a change of the lanceheights, the occurrence of lance failures has been considerably reduced without notably affecting the reaction ability of thesmelting furnace.

Request and Question Perspective in Interlanguage Pragmatics

Sung Kyu Yun,Woo-hyun Jung 한국사회언어학회 2004 사회언어학 Vol.12 No.2

Yun, Sung Kyu & Jung, Woo-hyun. 2004. Request and Question Perspective in Interlanguage Pragmatics. The Sociolinguistic Journal of Korea, 12(2). This paper is an interlanguage pragmatic study of request and question perspective. It aims to explore whether there are any differences in request perspective between American English native speakers and Korean EFL learners. To this end, this study employed a Discourse Completion Test, which consisted of eight situations. Data were collected from three different groups: native speakers of English; Korean learners of English; native speakers of Korean. The results showed that the learners deviated from native pragmatic norms in the choice of perspective in a relatively systematic way. The same held even more obviously in the use of please in interacting with request perspective. It was also shown that the mismatch between the native and nonnative groups in perspective was an instance of pragmatic transfer. The results suggested that the notions of imposition and politeness operated differently in perspective between the native and nonnative groups. It is expected that this study will shed light on the phenomenon of interlanguage pragmatics and the aspect of pragmatic transfer, revealing how learners differ from native speakers with respect to request perspective and what causes the differences.

19세기 초반 노상추(盧尙樞)의 백운동 별업(別業) 조성과 경영

김성우(Kim Sung-woo) 한국역사연구회 2010 역사와 현실 Vol.- No.78

The subject of this article is a historical figure, Roh Sang-chu (1746-1829). After ending his 28-year-long bureaucratic career as the associate commander at Gadeuk Naval Fort in 1813, he started a typical life of a rural yangban in his home town, Seonsan, Gyeongsang-do province for 17 years until his death in 1829. The most notable feature that involved the latter years of his life at hometown was the creation of the Baeg'un-dong manor ("byeol'eop"). He started creating the manor in 1814 and dedicated himself to developing it as a mean for economic development and social stability of the village, until his death there after a long illness. It is the locale of Baeg'un-dong that this research pays the greatest attention to. It was a border village under the jurisdiction of Dogae-myeon, Seonsan prefecture in the Joseon dynasty. As a border village, it was much closer to Bian prefecture than to Seonsan. For this reason, Baeg'un-dong now belongs to Uiseong County. The fact that it was alienated from the Seonsan prefecture, in spite of its belonging to the prefecture, is the most crucial factor which determined the historical-geographical character of the village. It was for this reason that Roh Sang-chu made efforts to build a shelter for illegitimate descendants there. He had an illegitimate son, Roh Seung-yeop(1796-1842). Roh Seung-yeop and his descendants led a socio-economically stable life under the guardianship of Roh Sang-chu, who acted as a patriarch of the manor. But their stable life began to derail after the death of Roh Sang-chu, due to their disadvantageous social status as 'illegitimates.' In the course of the downfall, the second and third generation of descendants of Roh Seung-yeop had to earn their lives as hired hands or loggers, leading a hard life in a small, secluded area inside Hwa'rim, village for the legitimate descendants of Roh's lineage. It testifies to the fact that the illegitimates were given little opportunities for their social activities during Joseon dynasty. Given this social background of Joseon dynasty, Roh Sang-chu s experimentation to create a manor for the illegitimate descendants had to end with incomplete success.

高麗中期의 民族敍事詩 : 東明王篇과 帝王韻紀의 硏究 A Study of old Korean Gests Dong-Myung-Pyun and Je-Wang-Woon-Ki

李佑成 成均館大學校 1962 論文集 Vol.7 No.-

Korean literature reaped a precious harvest of two splendid and long epic poems during the one century period from the late 12th to the late 13th century. These are Dong-Myung-Wang-Pyun (東明王篇), the Geste of King Dong-Myung by Yi, Kyu-Bo (1168-1241), and Je-Wang-Woon-Ki (帝王韻紀), the Geste of the Kings by Yi, Sung Hyoo (1224-1300). The Geste of King Dong-Myung clarifies in the opening chapters the remote genealogy of King Dong-Myung, hero and the founder of Koguryo; and in the main chapters, it depicts the King's history from the birth to his great work of foundation; and finally in the closing chapters, his history up to the coronation of King Luri who succeeded to his heroic works and also the impressing comments expressed by the poet. The Geste is written in Chinese poetry, composed of the main part of a little over two hundred and eighty lines and of the descriptive part of four hundred and thirty some lines. Each being a five-word line, the total Chinese word-characters used in the Geste amount to a length of three thousand six hundred (3,600). Je-Wang-Woon-Ki, the Geste of the Kings,(hereafter referred to as simply the Kings), consists of two volumes. The first volume carols the history of the ancient Chinese dynasties, from Bango (盤古) to Kum (金) and in the second volume, the history of Korea. The second volume is of two parts. The first part deals with the rise and fall of the Korean dynasties, starting from Dan-Goon (檀君), the remotes founder of Korea, to the dynasties of Wiman (衛滿), Sagoon (四群), Samhan (三韓) (Three-Kingdoms), Silla (新羅), Koguryo (高句麗), Bekje (百濟), later Koguryo, later Bekje and Balhe (渤海). The first part consists of two hundred and ten (210) seven-word lines, total character-words amounting to one thousand four hundred and sixty. The second part deals with the history of the period from the foundation of Koryo (高麗) down to the reign of King Choongyul (忠烈王) under which the poet lived. The second part is of seven hundred character-words in total, in one hundred and twenty (120) lines, each containing five words. The Geste and The Kings have attracted the attention of the scholar historians, both domestic and foreign, as the historical documents since much earlier days, but it is quite recently that they have come to be considered valuable from the viewpoint of literature. In fatc, they began to be revaluated as "folk epic" when the present author of this thesis published "A Study of the Generation of Yi, Kyu-Bo and Yi, Sung-Hyoo", at Pusan in 1956, and in the following year, Professor Chang, Duk-Soon made his thesis public under the title of "King Dong-Myung, an Epic", which found its place later in his "General Survey of Korean Literature". Quite recently, Professor Yi, Byung-gi presented a new viewpoint, in his "Complete History of Korean Literautre", that the Geste and the Kings are the truthful origin of "Kasa" (歌辭), the ancient folk poetry. About this new theory, however, the author would refrain from mentioning because it has no direct relation with the following thesis of the present author. The present author's interest lies rather in that these two poems in Chinese style should find a position with importance in the system of Korean literature, which has been so far neglected by the Korean literary scholars. A word about the thesis of Professor Chang, Duk-Soon. The thesis is sufficient enough to give the readers a profound understanding of the "Geste of King Dong-Myung" through his structural analysis of the narrative of King Dong-Myung and its detailed comparison with the western getse, which are done in his fluent, rich style. To the regret of the present writer, however, Professor Chang's studies on the Geste ended only in the field of said "analysis" and said "comparison", largely destitute of the due historical background of it. As the result, he ventured to ascribe the motive of the creation to a "nostalgic fidelity" of a Koryo-man to the prceeding Dynasty, Koguryo, and also to determine that the epic poem of the Koryo era was entirely an "accidental eruption of the 13th century". All the literary heritage is the products of the history. We cannot easily be contented by hastily treating our literary heritage. Therefore, the present writer particularly intends to examine the historical background of the Geste to comprehend the position of the poet's subjecthood and furhtermore grasp the true significance of the work from the viewpoint of resuscitated moving history of that age. A rough survey of the dynastic history of Koryo shows us that the Dynasty, since its foundation in 919 A.D., aimed high at expanding its territory towards the North as its state principle. This enterprising spirit of early Koryo had constantly been checked by the powerful suppression on the part of "Kuran"(契丹), and "Yojin"(女眞), two northern races. And without any chance, the Dynasty had to meet the Mongolian Aggression (1231-1256). In this warfare, the regime of "Choi"(崔氏) family ruled Koryo standing siege in KangWha Island. Choi's regime had resisted against the Aggressors thirty, long years before the Dynasty met its total defeat. And the former, the failure of the expansion policy was caused by the corruption and inability of the then ruling aristocracy; and the latter, the defeat at the hands of Mongolians, was brought about by the decrepitude of Royal House, and also by the reactionary bureaucrats who overthrew the Choi regime through treason. In the history of Koryo, however, we should not fail to observe the strong flow of the people's movements. During the period, 1128-1135, people urged the government to transfer the capital to Pyungyang, a border city, to face and suppress the enemy nation, "Kum" (金) (Yojin), and also they advocated that Koryo's King should be retitled as "emperor" like in China, setting up Koryo's own new era, which, till then, had been forbidden by Great China, the powerful dominator. Another incident of the people's movement is seen in heroic resistance against the enemy throughout the Mongolian Aggression. People fought at every part of the country in conjunction with the army, refusing to surrender to the Mongolians till the last. The high spirit and energy of the people had led to the formation of "Sam-Byul-Cho" Army which continued, in isolation from the government, its resistance war for four years until 1273. The 12th and 13th centuries mark the period of great trials suffered by the Korean race. The great spirit of resistance oppressed by the realities inevitably found it way to inwardness, and again was fermented to find its spout in the essence of literature. Yi, Kyu-Bo and Yi, Sung-Hyoo were the writers representing this troubled age, both of whom reached the greatness under favorable care of the Choiregime. They were "Rising Intellectuals" who heralded" New Officials", that is, the class of "Literary Intellectuals" during the second half period of Koryo. They were entirely different in character, from those old aristocrats who had held power during the first half period of the Dynasty. Therefore, these two literary men belonged to the transitional, progressive group of people who later prepared the seed-bed for the new culture. The new culture meant the culture for the people, while the old culture meant the culture forthe aristocrats. No wonder that folk epic such as the Geste and the Kings should be written by these "Rising Intellectuals", and not "accidental" at all. There is no objection in concluding that the Geste and the Kings both are the folk epic. However, we should discern the considerable difference which exists between these two poetical works, either in their subjects or either in their structure. The Geste carols one and single prototype, King Dong-Myung who was the hero of dynastic foundation; while the Kings deals with various, important historical happenings during the entire period from the earliest mythical foundation of the country by "Dangoon" down to the author's age. Here, just for the convenience's sake, the present writer take the liberty of calling the Geste a heroic poem; and the Kings, a history poem, regardless of the fact that a heroic poem and a history poem are essentially the same. Firstly, the writer desires to deal with the Geste laying stress on the following two points: (1) the method of the plot development, and (2) the characteristic of the prototype. In the heroic poem, the development of the plot differs according to the singularity or plurality of the hero prototype. When single, the plot develops towards the direction of the will of the hero; meanwhile, when plural, the plot becomes a succession of human contrasts, and collisions. In the Geste which is a biographic description of a King, the only prototype is King Dong-Myung himself. And the principal actions of the King are narrated in chronological order. However, Yi, Kyu-Bo, the author of the Geste tactfully dealt with the single hero additionally presenting his counterparts to produce a variety in the plot-flow. As the result, contrasts, collision occurs in succession constantly taking a new turn towards a third phase. The plot, therefore, constantly flows breaking the stalmate deadlock. Thus the Geste, which otherwise would have ended by an individuals biography, is heightened up to a realm of heroic poem. In the Geste, the poet succeeded in portraying the character of the hero. The willpower and ambition of the King as a hero are successfully expressed in his escape from Buyo,(扶餘) the capital, and in his founding of a new counrty and a new capital in the South and also in his fight against a neighboring state, "Biru-Kuk"(沸流國). The portrayal of the King's character as hero is vivid and acute in his strategy, violence, cruelty and egotism. The violent hero who exhausts every mean to accomplish his purpose falls easily, like a child, in the arms of his tender mother. Readers of the Geste are struck to find themselves disposed to agree with the hero's strategy, egotism and violence. In this, we are obliged to acknowledge the author's success in sculpturing the fresh, healthy, original humanity of the ancient type. The Geste is a success as a hero poem, but is still insufficient as a folk epic, that is, an epic of the Korean Race. The present writer is of opinion that King Dong-Myung certainly is a hero of a tribe, but not the common patriarch of the entire Korean Race. He is a heroic chief of the tribe of Koguryo which is the predecessor of Koryo "people" since it is evident, in history, that Koryo is the successor of Koguryo. And the author of the Geste so treated the King. In this strict sence, the Geste is, the present writer concludes, more of "heroic poem" than of "history poem". The great task of discovering the common patriarch of the entire race of this land was possible at the hand of Yi, Sung-Hyoo, a little later than Yi, Kyu-Bo's time. Yi, Sung-Hyoo described, with his wider range of view, the total historical activities of the entire Korean Race. In this sence, Je-Wang-Woon-Ki, the Kings is the comprehensive compilation of "folk epic", or perhaps, more properly, of "racial epic", and is characteristic of history poem. The Kings sets in its uttermost beginning Dangoon, as the sole patriarch of the entire Korean race, and clarifies that all the tribal states, which had ever existed in this land covering from northern end to south, are the equal descendants of Dangoon, the Great Patriarch. These tribal states mentioned in the Kings are Shira" (尸羅), "Koye" (高禮), "Ye" (濊), "Mek" (貊), "Buyo" (扶餘) and "Okju" (沃沮). Here, the position of Dangoon far surpasses, in height, that of King Dong-.Myunp. In Sam-Kuk-Sa-Ki (三國史記) (The History of Three-Kingdoms), not a word is mentioned about the racial patriarch. In Sam-Kuk-Yu.-Sa (三國遺事), another old history book, Dangoon is breifly mentioned but his dominion and successors are not intelligibly stated. It is very interesting to find that in the Kings, which was written only ten years later than Sam-Kuk-Yu-Sa, the myth of Dangoon is so surprisingly concrete. The formation of racial consciousness having its base on common Patriarch influenced greatly on the view of history to awaken the various tribes in constant conflict to the sense of homologue. History was no longer regarded by the dynastic unit. A new insight, after the Kings, was given to the view of history that a consistent flow of racial life, regardless of the rises and the falls of dynasties, formed the unending history of the Race. This new consciousness motivated the author of the Kings to begin at the remotest origin of the Race and trace all the way down through to his age, and have a long view towards the future of the race. Thus, the author viewed the complexity of the racial history, the extensiveness of its crosswise comprehension, the remoteness of its lengthwise survey, but he integrated them all in his Kings and reduced them all to Dangoon, the Racial Patriarch. . The Kings, this history poem, is indeed the greatest and the most valuable among all the works including Sam-Kuk-Sa-Ki and Sam-Kuk-Yu-Sa, that have ever been written by the hands of Korean prose writers. The 12th and 13th centuries represented by Yi, Kyu-Bo and Yi, Sung-Hyoo were the golden age of epic poetry in Korea. We regret, however, that this literary trend was not succeeded by their posterity. Epic poem died out with the death of those two poets, which results from the historical reality of Koryo Dynasty. Epic poetry is above all characteristic of collective consciousness rather than individual, for essentially it is a product of collective consciousness. The cosufferings and the co-resistance of the Korean race in the 12th and 13th centuries led the Race to the racial consciousness of common destiny-to the formation of a collective consciousness. Both heroic and history poems were based on this collective consciousness. Unless comes any split in this homologue, collective consciousness can be maintained. However, the historical reality of Koryo was different. The Mongolian invaders were the common enemy of the people of Koryo. Therefore the entire people rose and fought. But the ruling class of Koryo government forsook the people's volition to resist and shamelessly surrendered to the foreign aggressors. The government, even allied with the Mongolian army to destroy its own resisting army and people. By these means, the ruling class once more enjoyed the wealth and power under the grace of the Mongolian Empire; on the other hand, the detressed people suffered under the duplicated tax privations by both Koryo government and Mongolian colonial government. Here, the interests of the government and people were seriously conflicting. A total collapse came in the collective consciousness of the people as a race with common destiny. This tragic collapse, it meant the loss of the base on which was to grow the epic poetry. Thereafter, no epics were ever produced in the literature of Koryo, but its literature took two different flows: the one was Kyong-Ki-Che-Ka (景幾體歌), the literature of the ruling class; and the other, Chang-Ka (長歌) (meaning long ballad), which was the literature of the people. - The End -

Objectives : The purpose of the study was to assess the risk factors assumed to be related to the high frequency hearing loss in the noise-exposed male workers. Methods : 712 occupationally noise-exposed male workers were included in this cross sectional study. The subjects filled out a questionnaire on the history of noise exposure, hearing protection, otologic diseases, tobacco smoking, and were tested on height, weight, hematocrit, serum total cholesterol level, fasting plasma glucose level and arterial blood pressure level. Pure tone audiometry and otoscopy were conducted and the subjects were allocated into two groups according to whether they had 4000 Hz hearing loss or not. Results : The multiple logistic regression analysis showed that military noise exposure, poor wearing status of the hearing protection devices, increased age, long noise exposure duration, mean arterial pressure less than 80mmHg, high fasting plasma sugar are the factors significantly related to high frequency hearing loss (P〈0.05). On the contrary, there was no significant relationship between noise intensity, body mass index, serum total cholesterol level, smelling and high frequency hearing loss. Low hematocrit was shown to be a significant factor with a p-value less than 0.1. Conclusions : High frequency hearing loss in the noise-exposed male workers is related to military noise exposure, use of hearing protection devices, age, noise exposure length, fasting glucose level and mean arterial pressure, in this order. Appropriate use of the hearing protection devices has a great impact on the prevention of the noise-induced hearing loss.

정상과 갑상선 종양조직에서 사람 IGF-I 유전자의 발현

Many of the growth-promoting properties of growth hormone(GH) are mediated by insulin-like growth factor-I(IGF-I), a highly conserved circulating 70-amino acid peptide. Recent studies have shown that multiple mechanisms influence IGF-I gene expression, including transcription from two promoters, alternative RNA splicing, and variable polyadenylation. In thyroid tissue, thyroid stimulating hormone(TSH) and IGF-I are the most possible candidates for follicular cell proliferation and hypertrophy. Actually IGF-I had autocrine and paracrine effect for tissue growing. We prepared thyroid tumor tissue mRNAs using single step method for detecting IGF-I levels according to different tissues, i.e., thyroid adenoma or papillary thyroid carcinoma. We used Northern blot analysis for IGF-I mRNA and RNase protection assay (RPA) for IGF-I transcription start sites. For Northern blot, we used whole human IGF-I cDNA as a DNA probe and for RPA, we used IGF-I exon 1 containing noncoding promoter 1 as a riboprobe. We got good RNA bands from Northern blot analysis around 1 kb (IGF-IA) and 7.5 kb (IGF-IB) region. To clarify the amount of both IGF-IA and IB mRNAs, we measured autoradiographied signal of IGF-I mRNAs bands using densitometer. In IGF-IA signals, there's no change among liver and thyroid tissues, but in case of IGF-IB mRNA bands, the signal was markedly increased in thyroid carcinoma tissues than that of normal thyroid tissue (85% vs 14%). In the study of RPA, all thyroid tissues used the same transcription start sites as those of liver's. We concluded that that this different regulation of IGF-I mRNA was originated from tissue specificity. That meant some tissue specific transcription factor/s were related to tissue IGF-I expression.
