이 연구는 탐사보도에서 소명의식은 필수조건인지, 탐사보도 기자들은 어떤 소명의식을 가지고 있는지, 가지고 있다면 소명의식을 구체적으로 어떻게 실천하는지 탐구했다. 이를 위해 막스 베버(Max Weber)가 주장한 ‘소명(Beruf)’ 개념을 이론으로 적용했다. 연구대상은 뉴스타파 취재팀이며, 연구방법은 참여관찰과 심층면담을 병행한 문화기술지이다. 연구 결과 첫째, 뉴스타파 기자들은 탐사보도에서 소명의식을 중요하다고 생각했다. 취재팀 내에서는 소명의식의 실재에서 차이가 발생했는데 아직 이렇다 할 소명의식을 형성하지 기자들은 직장에 대한 소속감 저하와 탐사보도 기자로서의 정체성에 혼란을 겪고 있었다. 둘째, 취재팀 내에서 ‘신념의 화신’으로 통하는 최경영과 한상진 기자의 경우 뉴스타파의 열린 뉴스 생산 방식 속에서 소명의식을 적극적으로 보도에 투영하고 있었다. 이들 보도의 특징은 ‘자신감을 바탕으로 한 집요함’이었다. 이들은 보도 건수나 취재력 등에서 취재팀 내에서 긍정적 평가를 받고 있었는데 성과의 원동력은 소명의식이었던 것으로 판단됐다. 셋째, 신념의 과잉으로 인한 오류가 관찰됐다. 최경영은 “가치저널리즘”을 추구하며 날카로운 비판 보도로 ‘선지자’의 모습을 보이기도 했지만, 때로는 자신의 시선이나 관점이 과다해 ‘광신도’의 모습도 보였다. 신념의 과잉은 사실의 과장, 적대적 공격, 그리고 ‘끼워넣기’ 등으로 나타났다. This research explored if the sense of calling is a necessary condition in investigative journalism, what kind of calling investigative journalists have, and how to carry out their calling if they have. The research subject was the news reporter team in Newstapa, and the research method was ethnography which concurrently performed participation observation and in - depth interview. Research results are as follows. First, news reporters thought that the sense of calling was important in investigative journalism. In news reporter team, there was a difference in the reality of the sense of calling, and the reporters who had not yet formed calling to do so were confused by the deterioration of belonging to the workplace and the identity of as investigative journalist. Second, Choi Kyoung-young and Han Sang-jin, who are considered ‘icon of calling’ in the team, were actively reflecting on their calling in their news stories using the open-minded news production system. The characteristic of these reports was ‘obstinacy based on confidence’. They were evaluated positively in the team in terms of the number of reports and coverage, and the driving force of the performance was judged to be the sense of calling. Third, errors caused by the excess of belief were observed. Choi Kyoung-young pursued “value journalism” and showed the appearance of ‘prophet’ through sharp criticism reports, but sometimes his gaze or perspective was excessive, and he also showed the appearance of ‘fanaticism’. The excess of belief appeared as the exaggeration of the facts, hostile attacks, and ‘embedding’.

최준혁,이관우,김효정,이동훈,이종우,김정은,엄현채,김경미,최성이,정윤석,김현만 대한내분비학회 2002 Endocrinology and metabolism Vol.17 No.5

연구배경: 제2형 당뇨병에서 나타나는 인슐린 저항성은 간, 지방, 근육 같은 말초조직에서 인슐린의 작용이 떨어지는 것을 말한다. 제2형 당뇨병의 발생기전에 인슐린 저항성과 인슐린 분비능 저하가 같이 관여함은 잘 알려진 사실이다. 인슐린의 세포내에서의 저항성을 규명하기 위한 인슐린의 세포내 신호전달체계에 대한 연구가 활발히 진행되고 있으며 몇몇 연구에서 인슐린 저항성을 가진 골격근육에서 IRS와 관련된 PI3-kinase의 활성감소와 Akt kinase의 활성감소를 보고하고 있으나 아직까지 명확하게 그 기작이 설명되어지지 않고 있다. 본 연구에서는 정상성인, 제2형 당뇨병 환자를 대상으로 경구당부하검사 및 인슐린 클램프검사를 시행하고 인슐린 클램프 검사시 대상인의 근육을 채취하여 인슐린 신호전달 체계(IR-β, IRS, Akt(PKB, Rac) kinase, GSK-3)를 연구하였다. 방법: 연구대상자는 한국인으로서 경구당부하검사상 정상인 및 당뇨병 환자 각각 11명, 9명을 대상으로 하였으며, 정상인은 건강인으로 과거력상 당대사에 영향을 줄 질환이 없고, 현재 당대사에 영향을 줄 약물 복용 및 다른 소견이 없는 경구당부하검사상 정성 내당능을 보이는 대상자로 하였다. 당뇨병환자는 모두 제2형 당뇨병 환자로 이환기간이 만 5년 이내인 경우로 하고, 인슐린으로 치료하는 대상자는 제외하도록 하였다. 대상자의 연령, 체질량지수, 체지방량, 공복시 총콜레스테롤, 중성지방, 고밀도지단백 콜레스테롤 및 HbA1c, 인슐린, C-peptide를 측정하였고, "HOMA model"을 이용하여 베타세포의 기능와 인슐린저항성 정도를 평가하였다. 정상혈당클램프 검사(euhlycemic hyperinsulinemic clamp test)를 시행하고 인슐린 투입 전과 인슐린 투입 30분후, 두차례에 걸쳐 대퇴부 근육생검을 실시한후 western 법으로 IR-β, IRS, Akt kinase, GSK-3의 인산화량을 측정하였다. 결과: 정상인 11명과 당뇨병 환자 9명을 대상으로 하였으며 대상자의 평균 연령, 평균 체질량지수, 체지방량, 허리/엉덩이 둘레의 비(waist hip ratio; WHR)는 두 군간에 차이가 없었다. 평균 공복혈당은 정상군 98.0±0.3㎎/dL, 당뇨병군 208.1±16.5㎎/dL(p<0.05), HbA1c는 정상군 5.4±0.5%, 당뇨병군 9.2±0.6%(p<0.05)였다. "HOMA model"을 이용한 베타세포의 기능과 인슐린저항성은 정상군 56.4±8.5%, 1.4±0.2, 당뇨병군 72.2±52.3%(p<0.01), 10.2±6.3(p<0.01)였으며 정상혈당클램프 검사상 포도당 이용률은 정상군 8.2±0.6㎎/㎏/min, 당뇨병군 3.7±1.1㎎/㎏/min(p<0.01)로 정상군과 당뇨병군간에 유의한 차이를 나타내었다. Western blot법으로 IR-β, IRS, Akt kinase, GSK-3의 인산화량을 인슐린 투입전과 인슐린 투입 30분후 측정하였을 때 IR-β에서는 정상군이 103.9±2.3에서 241.3±18.6, 당뇨군이 108.9±2.2에서 198.7±6.3으로 증가하였다(p=NS). 이는 인슐린 투입후 당뇨병군이 정상군과 비교하여 인산화량의 증가정도가 통계적인 차이가 없었다. IRS에서는 정상군이 111.6±7.3에서 295.6±17.2, 당뇨군이 114.5±6.1에서 222.0±23.2로 증가하였으며(p<0.05), 인슐린 투입후 당뇨병군이 정상군과 비교하여 인산화량의 증가정도가 약 24% 감소하였다. Akt kinase에서는 103.4±6.0에서 416.8±29.5로 증가하였으며(p<0.01), 인슐린 투입후 당뇨병군이 정상군과 비교하여 인산화량의 증가정도가 약 43% 감소하였다. GSK-3에서는 정상군이 107.7±6.7에서 595.7±28.1, 당뇨군이 104.3±4.8에서 443.3±12.9로 증가하였으며(p<0.01), 인슐린 투입후 당뇨병군이 정상군과 비교하여 인산화량의 증가정도가 약 25% 감소하였다. 결론: 제2형 당뇨병 환자에서 정상인과 비교하여 인슐린 자극후 IR-β는 인산화량의 증가정도가 큰 차이가 없었으나, IRS, Akt kinase, GSK-3에서는 인산화량의 증가 정도가 감소되는 것으로 보아 상위 인슐린 신호전단체계부터 결함이 있는 것으로 생각된다. Background: The glucose uptake rate is the limiting step in glucose utilization and storage. The failure of insulin to stimulate glucose uptake in muscle appears to be a primary defect of insulin resistance. This study was undertaken to examine the effect of physiological hyperinsulinemia on the phosphorylation of the insulin receptor (IR-β), insulin receptor substrate (IRS), Akt kinase and GSK-3 in isolated skeletal muscle, in people with type 2 diabetes(n=9) and control subjects(n=11). Methods: 75g OGTT and euglycemic hyperinsulinemic clamp test were done. And vastus lateralis muscle was obtained before and 30 min into the euglycemic clamp. Western blots were performed for tyrosine phosphroylation of insulin receptor substrate (IRS) and phosphorylation of the insulin receptor(IR-β), Akt and GSK-3. Result: There were no statistical differences in the mean age, BMI and body fat between the control subjects and diabetic patients. The fasting blood sugar and HbA_1c in controls and diabetic patients were 98.0±0.3 and 208.1±16.5ng/dl, and 5.4±0.5 and 9.2±0.6%, and 1.4±0.2 in the control subjects, and 72.2±52.3%(p<0.01) and 10.2±6.3(p<0.01) in the diabetic patients, respectively. The insulin resistance from the euglycemic hyperinsulinemic clamp test were 8.2±0.6㎎/㎏/min and 3.7±1.1ng/㎏/min in the control subjects and in the diabetic patients, respectively(p<0.01). Compared with the normal controls, insulin-stimulated IR phosphorylation was no different to that in the diabetic patients. However, insulin-stimulated IRS phosphorylation, insulin-stimulated Akt phosphorylation and insulin-stimulated GSK-3 phosphorylation were reduced in the diabetic patients compared with the normal controls by 24, 43 and 25%, respectively(p<0.05). Conclusion: In Korean type 2 diabetic patients, the insulin resistance may be due to the impairment of the upstream insulin signal molecular network. Further studies will focus on determining whether these signaling defects are the cause of the development of insulin resistance, or secondary to the altered metabolic state, associated with type 2 diabetes mellitus (J Kor Soc Endocrinol 17:685∼697, 2002).

Uruguay Round(UR) has a lot of implication in the forest product market as well as the other sectors of the economy. Jujube, one of the major forest products in Kyungsan county would be affected by the free trade resulting from the agreement on UR. To establish effective policy measures dealing with negative effects on free trade, if any, the effect of UR on Jujube producers should be figured out. In this context, the purpose of this study are (1) estimating the demand, supply and its price functions of the Jujube market and (2) forecasting the effect of UR on Jujube growers. The result is such as; Demand funtion : Q^d_t〓 - 19032-714.3203·ln p_t+5179.3947·ln GNP_t Supply function : Q^s_t= - 6975.15+266.871516·ln P_t-1+1159.4668·ln Q_t-1 Price function : ln P_t=1.41225-0.02004·ln Q_t-1+0.053464·ln P_t-1+0.693957·ln GNP The damage to the Jujube growers is estimated to be 34 billion won, 37 billion won, 39 billion won and 48 billion won by 2001 if jujube's tariffication rate in the year of 2001 is reduced 30% 40% 50% and 90%, respectively.

In this work, we examined the electrical and mechanical characteristics of TFD devices for various top electrode materials by measuring barrier height and performing ASE depth profile. It was found that the shift of current-voltage(Ⅰ-Ⅴ) characteristics of TFD device depends on the top electrode material. The main reason of the asymmetry in Ⅰ-Ⅴ curve was the differences in barrier height of top and bottom electrodes, and chemical composition at the interface region between top electrode and insulator layer also was important reason. The barrier heights(φ_B) evaluated from temperature dependence of the Ⅰ-Ⅴ relation are 0.7795(Al) 1.0287(Ti) and 1.2928(Ta) eV.
