Recently, environmental aspect of coporates' activities becomes a very important social problem. And the needs of the environmental accounting informations are growing rapidly. It is the purpose of this paper to examine the factors which affect the disclosure level of coporates evironmental accounting information. Some researches were conducted on this topic and they had measured the amount of information disclosed by the physical measures such as the number of words, lines or pages. But we have measured it by the amount of messages(contents) in the disclosed information. By the results of the analysis, we have found some significant relationships between the level of disclosure of environmental accounting informations and characteristics of firms. There are statisticaly significant positive relationships between the each of following three variables-the environmental friendliness of a firm, the size of a firm and the ratio of minority shareholders - and the disclosure level of environmental accounting information. But we could not find any significant relationships by using the number of words. lines or pages as measures of disclosure level.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

Tufftride處理 後 高周波 硬化處理된 軟鋼의 機械的 性質및 高周波 硬化 特性에 관한 硏究

田炳旭,李相允 東亞大學校 大學院 1984 大學院論文集 Vol.8 No.2

A combined heat treatment of tufftride and induction-hardening treatment for mild steel specimens has been carried out to investigate into the improvement in mechanical properties and some induction-hardening characteristics. The results obtained from this experiment are given below; 1. Optical micrographs have shown to vary as changes in the rate of travel at a given output power during induction-hardening, resulting in the decomposition of compound layer and the formation of the Fe-C-N martensitic structure when the travel rate of 3.1 mm/sec. is maintained. 2. Hardness measurements have revealed that specimens treated at the travel rate of 6.2 mm/sec. show an increase in hardness compared to specimens tufftride-treated due to the fact that the content of solute atom dissolved in ferrite increases during induction-hardening, whereas for travel rates of 4.4 mm/sec. and 3.1 mm/sec. the formation of martensitic structure gives a considerable increase in hardness. 3. It has been found that for a given output power as the rate of travel decreases hardness increases, and that the travel rate of 3.1 mm/sec. shows a great increase in surface hardness and effective hardening depth as compared to the travel rate of 4.4 mm/sec. 4. Specimens tufftrided, induction-hardened, and then tempered have shown a somewhat decrease in hardness and an increase in toughness compared to that obtained before tempering treatment. 5. Tensile test has shown that the tensile strength of mild steel specimens treated by this combined heat treatment increases as tufftride treating time increases and as the rate of travel decreases. 6. It has been shown that for a given rate of travel under the same panel control during induction-hardening the output power increases with increasing the diameter of specimens, and smaller specimens generally shows a higher hardness value.

이상엽,김윤진,김형회,손한철,전태용,심문섭 대한비만학회 2002 The Korean journal of obesity Vol.11 No.2

연구배경 : 최근 식욕조절인자로 관심이 집중되고 있는 그렐린(ghrelin)은 식사 전후로 독한 일중변동을 보인다. 하지만, 지금까지는 실험적으로 일정한 열량의 표준 음식을 일정한 식사시간에 공급한 이후 그렐린의 농도 변화를 관찰하였다. 저자 등은 평소 아침 식사시간이 각기 다른 사람들에서 아침 식사 전후의 혈장 그렐린 농도 변화를 관찰하여 향후 외래 환경에서도 그렐린 관련 연구가 가능하도록 기초 자료를 제공하고자 하였다. 방법 : 연구에 대한 설명을 듣고 동의한 23.4 ~ 35.5세 사이의 비교적 건강한 동양인 남자 4명을 대상으로 하였다. 신체 계측을 한 후 이중 에너지 방사선 측정법 (Lunar prodigy, GE medical systems, Waukesha, Wisconsis, USA, 이하 DEXA)으로 체지방을 측정하였다. 연구 대상자 모두 평소 아침 식사시간이 일정하였지만 연구 시작 2주전부터 아침 식사시간을 엄격히 고정하도록 하였다. 스트레스가 없는 상태에서 아침 식사를 하지 않는 지원자는 오전 6시 30분부터, 나머지는 아침식사 시간 1시간 전부터 1시간 간격으로 점심 식사 전인 오전 11시 30분까지 채혈하였다. 각각의 검체로 부터 혈장 그렐린은 상업적인 방사선면역측정법 (Phoenix Pharmaceuticals, Inc., Belmont, CA)으로 측정되었다. 랩틴은 Ⅰ-125 표지 랩틴을 이용한 이중항체 방사선면역측정법으로, 혈장 인슐린은 항체 부착관을 이용한 방사선면역측정법으로, 혈당은 포도당산화 효소법에 의해 Synchron LX 20 (Beckman Coulter, Inc, Fullerton, USA)으로 측정하였다. 결과 : 연구 대상자의 체질량지수는 22.9 ~ 27.1 kg/㎡이었고, 허리둘레는 80.3 ~ 93.3 cm이었다. DEXA로 측정한 결과 전체 체지방과 체부지방 비율은 각각 27.1 ~ 31.8%와 32.7 ~ 32.4%이었다. 아침 식사를 하지 않는 자를 제외한 나머지 연구 대상자의 아침 식사 직전의 식후 2시간의 혈장 그렐린 농도는 각각 113.0 ~ 800.0 pg/mL, 78.3 ~ 553.0 pg/mL이었고 랩틴 농도는 각각 4.9 ~ 5.1 ng/mL, 4.4 ~ 4.7 ng/mL 이었다. 혈장 그렐린 랩틴 농도는 아침 식사 직전에 비해 식사 2시간 후 각각 7.2 ~ 30.9%와 7.8 ~ 10.2%감소되었다. 아침식사를 하지 않는 대상자의 경우 인슐린과 혈당치가 변화가 없음에도 불구하고 혈장 그렐린 농도는 오전 7시 30분에 가장 낮았다. 그 외 연구 대상자에서는 각기 다른 시간이더라도 아침 식사 2시간 후의 혈장 그렐린 농도가 가장 낮았다. 결론 : 평소 아침 식사시간이 다른 사람들에게서 혈장 그렐린 농도는 각기 다른 아침 식사 2 시간 후에 가장 낮았다. 아침 식사를 하지 않는 경우에는 혈장 그렐린 농도가 오전 7시 30분에 가장 낮았다. Background : Recently, the particular interest is on ghrelin, the dietary control factor among many scientists and it a toxic diurnal variations has been demonstrated before and after meal. However, the experimental approach has been only to see the changes in the concentration of ghrelin after intake of meals standardized with fixed calories at scheduled meal hours. the authors of this particular experiment have tried to observe and record the changes in concentrations of plasma ghrelin of persons with different breakfast hours. This might help in providing a basis for further possible studies in outpatient setting. Method : A group of four relatively healthy males whose ages between 23.4 and 35.5 with prior agreements were selected for this study. After body measurements, body lipid status was measured based on Lunar prodigy (GE medical systems, Waukesha, Wisconsin, USA) which is also referred to as DEXA. All of the selected persons had somewhat fixed breakfast time; however, they were asked to strictly keep their breakfast time fixed and steady starting two weeks before the beginning of experiment. The bloods of those who skip their breakfast without any particular stress were sampled at 6:30 AM, whereas the rest had different schedule, whose bloods were sampled every hour starting 1 hour before the first meal of the day till just before lunch (11:30 Am). From each blood sample, the level of plasma ghrelin was measured using the commercial radioimmune assay (Phoenix Pharmaceuticals, Inc., Belmont, CA). Leptin was measured with double antibody radioimmune assay using Ⅰ-125 labelled leptin, plasma insulin with radioimmune assay using antibody attachment tube, and blood sugar with Synchron LX20 (Beckman Coulter, Inc, Fullerton, USA) using glucosylation enzyme method. Result : The body mass index of the volunteers was 22.9 ~ 27.1 kg/㎡, with 80.3 ~ 93.3 cm waist circumference. Based on measurements by DEXA, the rates of total body lipid and trunk lipid were each 27.1 ~ 31.8% and 32.7 ~ 32.4%, respectively. The concentrations of plasma ghrelin of those who consume their breakfast before and 2 hour after their breakfast are 113.0 ~ 800.0 pg/mL and 78.3 ~ 553.0 pg/mL. The concentrations of leptin are 4.9 ~ 5.1 ng/mL and 4.4 ~ 4.7 ng/mL. Compared to the concentration of plasma ghrelin and of leptin recorded just before breakfast, it showed 7.2 ~ 30.9% and 7.8 ~ 10.2% decrease, respectively, 2 hours after breakfast. For those who skip their breakfast, the plasma concentration of ghrelin was recorded the lowest at 7:30 AM, even though there was no change in insulin and blood sugar. The rest of the subjects had their lowest plasma ghrelin concentration at 2 hours after breakfast, despite their different meal schedule. Conclusion : The persons with different breakfast hours had their lowest plasma concentration of ghrelin at 2 hours after breakfast. In contrast, the persons who skip their breakfast had their lowest concentration at 7: 30 AM.

Mo-disilicide 박막은 n-Si(100) 기판위에 전자선 증착과 이어지는 진공 또는 질소 분위기에서 급속 열처리(RTA : Rapid Thermal Annealing) 장치에 의한 열적 확산(thermal diffusion)법에 의해서 만들어졌다. 이들 박막의 화학적 조성과 morphology는 XRD, AED(ADP), TEM, NOM에 의해서 분리되어졌다. Mo/Si계의 안정된 최종상은 tetragonal-MoSi₂였고, 표면 morphology와 grain size는 상호 의존하며 열처리 온도에 따하서 크기가 증가되었다. 상온에서 증착한 박막에서는 계면에서 얇은 SiO_2 층이 보였고 이 층의 존재로 Si의 확산이 억제됨을 확인하였으며, 기판온도를 400℃로 유지하며 pre-annealing을 120분 동안 부여한 시료에서는 Mo-silicide가 columnar 구조로 성장됨이 보였다. 그리고, 전기적 특성은 sheet 저항과 Schotty 장벽높이가 조사되었는데, 열처리 온도 증가에 따라 감소하는 sheet저항은 grain size에 의존하며, 최저치는 700℃에서 1분 동안 열처리 한 시료의 값인 2.1Ω/□으로 열처리 온도 증가에 대해 더 이상 변화하지 않는 최종적인 값이다. 그러나 Schotty barrier height는 0.56eV로 열처리 온도, 분위기에 따라 변화하지 않으며 hexagonal-과 tetragonal-MoSi₂둘 모두에서 같았다. Molybdenum disilicide films have been prepared onto n-Si(100) substrates with electron-beam deposition and sequently post-annealing by rapid thermal annealing in the ambient of N₂ or vacuum. The chemical compositions and morphology of films were analyzed by XRD, ADP, TEM, and NOM methods. We confirm that the stable phase of Mo/Si system is tetragonal-MoSi₂ phase, and the surface morphology and grain size were depended upon the annealing temperature. There are SiO₂ layers at the interface of MoSi₂ film evaporated at room temperature and the thermal diffusion of Si was interrupted by the layers. However, the thin films with the substrate temperature of 400℃ have growned to the MoSi₂ with columnar structure. We measured the electrical properties, the sheet resistance and Schottky barrier height, of MoSi₂ thin films. The sheet resistance was depended upon the grain size and the smallest value was 2.1Ω/□ at room temperature after annealing at 700℃ for 1 min. The Schottky barrier height was independed upon the annealing temperature and ambient, and was about 0.56eV for hexagonal- and tetragonal-MoSi₂.

Pancreas is known for the unfavorable soil to the metastatic carcinoma, and pancreatic metastasis is achieved after systemic dissemination was developed. The primary tumors of metastatic pancreatic carcinoma are breast, lung, Iymphoma, malignant melanoma, leukemia, stomach. and colon. The breast carcinoma is the commonest tumor to metastasize to pancreas and both tumors are related to estrogen receptor for tumor growth. In the present case, tumor cells had small round nucleus and showed indian file infltrating pattern and lack of cohesion, which are seen in infiltrative breast carcinoma. The patient was underwent radical mastectomy due to infiltrative ductal carcinoma three years ago. And also the tumor cells showed nuclear reactivity to immunostaining for estrogen receptor In combination of the histopathologic. immunohistochemical, and her past history, we concluded that breast carcinoma was metastasized to pancreas, and we report a case of metastatic pancreatic carcinoma from breast with review of literatures.
