Backgroud: DHEA-S is the most abundant steroid hormone in circulation, and primarily secreted from the adrenal cortex, but its physiological role is little known. One of the characteristic features of DHEA-S is progressive decrement of plasma DHEA-S level with advancing age, in contrast, plasma levels of other adrenal hormones are not chaging or littie decreasing. To grasp the trends of plasma DHEA-S level and DHEA-S/cortisol ratio by age in healthy Korean, we measured the plasma DHEA-S levels and DHEA-S/cortisol ratios in healthy Korean. Methods: Healthy Korean(men: 99, women: 102, age range: 15-97 year old)were studied. Subjects were not taking drugs(such as glucocorticoid or androgenic medication) or cigarettes known to modify the plasma level of DHEA-S and cortisol, and had no evidence of hepatic, renal disease or hyperlipidemia as determined by serum lipid, bilirubin, SGOT, SGPT, BUN, creatinine. Data were analyzed by 10-year age group for men and women: i.e, 10-19, 20-29, 30-39, 40- 49, 50-59, 60-69, 70-79, 80-89 and 90 year or more. Plasma DHEA-S levels were measured by using a commercially available RIA kit with 125I labeled-DHEA-SO4(Coat-A Count DHEA-SO4), and for the measurement of plasma cortisol levels, commercial Gamma Coat TM[125I] Cortisol Radioimmunassay Kit was used. Results:. 1) In both men and women, plasma DHEA-S level showed high interindividual variation within the same age group. 2) There were individual sex differences in plasma levels of DHEA-S, in all age groups, plasma DHEA-S levels were significantly higher values for men than for women. 3) Maximum plasma DHEA-S levels(men; 237+-3.35 ug/dL, women; 108+-17.5 ug/dL) were at third decade in both men and women. 4) Both men and women showed the continuous decline in plasma DHEA-S level with age. These age-related decline was more prominent in men than in women(men; y= -3.152 * +292.6, r2= 0.8459, P$lt;0.05, women; y= -1.417 * +143.3, r2 = 0.7278, P$lt; 0.05). 5) As an index of aging, there was no stastical difference between DHEA-S and DHEA- S/cortisol ratio. Conclusion: In healthy Korean, there were high interindividual variation of plasrna DHEA-S levels. In both men and women plasma DHEA-S level was peak at third decade, and from when it declined progressively with age. These results suggest that although the reliability of single plasma DHEA-S measurement are limited, the decline of DHEA-S with advancing age might be a specific marker of endocrinologic hormonal milieu(aging index). Also, concerning to individual adrenal secreting capacity, we measured DHEA-S/cortisol ratio. But we did not found that plasma DHEA-S/cortisol ratio is superior to the plasma DHEA-S level as an aging index. (J Kor Soc Endocrinol 12:245-254, 1997)

The Tragedy of Pudd’nhead Wilson에서 정체성의 문제

이재만 ( Lee¸ Jae-man ) 현대영미어문학회 1998 현대영미어문학 Vol.16 No.2

This novel is the story of a young man’s mistaken identity. He thinks he is white, but is in reality colored, and he is heir to wealth without knowing his claim is false. He lives as a free man, but is legally a slave. When he learns ― a true fact about himself, he comes to ruin not through the knowledge of his physical status, but through the weakness belonging to both races. The psychological twins in this novel are switched identities, mistaken identities, and foils. Thomas a Becket Driscoll and Chambre de Valet are switched identities, and so they are naturally mistaken ones at the same time. David Wilson and Roxy are mistaken identities and they also become foils to each other. In fact, the false Tom is a foil to David Wilson, not to Chambers. Like this, the major characters of the novel are interrelated with each other. The fictional and conventional injurious effects of the slavery which represented largely centering around the life and consciousness of Roxy, Tom and Chambers falls to the white masters as well as the negro slaves. The slaves lead a forced and implanted lives instead of their own, which results in the loss of their self-interest and even self-identity amid the mire of fictious institutional fetters. The Psychological twins’ effort of trying to discover their true identities all come to end in a nightmare. Such result is specially notable in Mark Twain’s later novels through his deepening pessimism in his later years. His conclusion may be that man’s true identity cannot be found and held up in the social situation of “damned human race” in which there prevail the acquisitiveness of the Gilded Age, race prejudice, hypocritical view of religion, man’s cruelty with each other, neo-aristocracy, and miscegenation.

Aims: Incisional hernia is one of the complication following abdominal operation. Patients undergoing liver transplantation have a high risk of developing an incisional hernia because of immunosuppression. The purpose of this study is to review incisional hernia cases after liver transplantation and to identify the risk factors for hernia formation. Methods: We retrospectively reviewed and analyzed the medical records of the ninety-four incisional hernia patients after liver transplant recipients from January 2000 to December 2015 in single center institution. Results: 1463 underwent adult liver transplantation during the study period. 94 Incisional hernia patients were found among them. The overall incisional hernia rate was 6.4 %. Mean age was 54 years old and 76.6 % were men. No significant difference was observed for sex, diagnosis, smoking, alcohol, albumin, Child-Pugh score, MELD score, intensive care unit stay, hepatorenal syndrome, ventilator, spontaneous bacterial peritonitis, diabetes, bile leakage, wound problems between patients with incisional hernia and patients without incisional hernia. The characteristics of patients with incisional hernia showed old recipient, more body weight, higher body mass index, living donor recipient compared with patients without incisional hernia. Hypertension, tuberculosis, rejection, postoperative complication event before hernia were significant risk factor (p<0.05). Conclusions: Present study identifies the risk factors for incisional hernia. Surgeons should strive to reduce the risk of incisional hernia after adult liver transplantation.

Fabry-Perot 分光法의 理論的 考察

李在萬 群山大學校 1981 論文集 Vol.2 No.-

The method of reconstructing the spectrum from interferogram obtained with the Fabry-Perot interferometer is discussed. This interferogram is the incoherent superpositions of many interferograms of Fourier Transform Spectroscope with different contractions. It is shown that the spectrum can be recovered by deriving the original Fourier Transform Spectroscope interferogram and by Fourier transforming it numerically. The half width of the instrumental function is inversely proportional to the maximum distance between the two reflecting layers as in Fourier Transform Spectroscope and does not depend on the reflectivity.

Natural Resources Could refor to all the living and nonliving endowment fo the earth. Also, Natural Resoures is a prerequisite for Economic Growth in Countries. But, Traditionally, Our Country in Very poor in the resources. and so, We have to import the scarce in resources from abroad. Comsequently, in this, the general state of things a study on Resources and Economic Growth that could be an abstacle factor in korean Economic Development. Also, I think the subject demands colse further investigation. The structure of this thesis consists in five chapters, chapter I introduce the aim, method and scope of this study, chapter Ⅱ considered the Resources and Wconomic Growth. chapter Ⅲ deals with the resource supply and demand the present condition in korea, and its a prospect. chapter Ⅳ presented the point a issue of resource supply and demand in Korea, and that a direction of the long time Resource Policy. In chapthe Ⅴ, the above mentioned comtents are summarized as a conclusion. In conclusion we should say that the over-all Resource Problem of Korea at present is very serious. but our country is not only in the depths of despair because hold a latent resources and rich in human resource. So, We should grope for possibilities of resource Development, such as, stabilized Security of resouras, Saving for emergency of resources, research of undeveloped resources, diversification of import markets. etc,.

Demand and supply of industrial water in Chonju area is analysed. Because the industrial water is not enough for the drought period, many factorys at the Chonju industrial technology services center are damaged in 1994. Industrial water of the area is taken at Chon-mi intake field. But the intake rate is decreased by 2.4% per year due to silting and compaction of the a quifer port. Therefore the intake rate is not enough to supply the damand of water the center. In this study, The water from seqage treated id wuffested as an alternative for sev-ere drought period. The alternatives for a long time period are suggested : the j-oint operations of Ku-I reservoir and Ockjung reservoir, Da-a reservoir and Kum river barrier reservoir, Da-a reservoir and Young-dam reservoir.

『허클베리 핀의 모험』에서 정체성

이재만 현대영미어문학회 1999 현대영미어문학 Vol.17 No.1

The purpose of this paper is to inquire into the identity in Huckleberry Finn by analyzing the work that deal with the typical situations causing the Identity problems. In this book, major characters such as Huck Finn, Jim, the King and Duke assume various masks to hide their real identities to bolster their pretense to be a pirate, to help others, or to cheat the ignorant. Huck assumes either voluntarily or through external pressure ten different identities during his progress down-river. After engineering the "death" of his old identities as Pap's bad boy and the Widow Douglas's good boy, he is the self-chosen castaway with Jim on Jackson's Island. The raft provides the only home to this unique family composed of a runaway black slave and a runaway white Southern boy. Only on the raft can Huck assume his true identity, and he must play false roles whenever he ventures off the raft among the shore society. But in Huckleberry Finn, Twain seems to imply that to search for identity and meaning apart from society, through escapee, can only be temporary, and thus an inadequate solution. The raft is sullied by the invasion of scalawag society which the Duke and King represent. And of course the King and Duke, who dress to suit whatever the larcenous occasion, are master manipulators of reality and appearance. To save Jim from slave hunters, the King runs off a handbill describing Jim as a runaway slave. But the bill counterfeiting Jim's identity in order to save him is used later to enslave him. Low on money, the King uses the counterfeit bill as proof that Jim is worth a $200 reward, and sells Jim for $40 while Huck is away. In conclusion, using various types of devices--the impostors, the switched identity, the mistaken identity--Mark Twain reveals the central aspect of his own character, explores the dilemma of his own duality, and confronts man's irreconcilably dualism. And one of the essential bases of Mark Twain's modernity can be found in the depth and importance of the identity of his work.
