Central diabetes insipidus (DI) is a syndrome characterized by thirst, polydipsia and polyuria. Langerhans cell histiocytosis is one of the etiologies of DI. Recently we experienced a central DI associated with Langerhans cell histiocytosis. The 44 years old female patient complained right hip pain polydipsia and polyuria. We carried out water deprivation test. After vasopressin injection, urine osmotic pressure was increased form 109mOsmol/Kg to 327mOsmol/Kg (300%). Brain MRI showed a thickened pituitary stalk and at hot bone CT.CT guided biopsy revealed abnormal histiocytes proliferation and abundant lymphocytes, The final diagnosis was central DI associated with systemic Langerhans cell histiocytosis invading hip bone, L-spine and pituitary stalk. Desmopressin and etoposide chemotherapy were performed to the patient.

이두형,최병열,장원철,서길수,이태진 영남대학교 공업기술연구소 1999 工業技術硏究所論文集 Vol.27 No.1

Mesoporous MCM-41 exibits a hexagonal arrangement of uniform mesopores whose dimensions may be engineered in the range of ∼20Å to greater than 100Å. The MCM-41 typically have high surface areas above 1000m2/g, and then capacities of MCM-41 to accommodate the larger hydrocarbon is still higher than the general molecular sieve. At the present, many surfactants as organic templates have been proposed for various formations of these MCM-41. In this study, we synthesized mesoporous MCM-41 which has a spherically hexagonal structure. Also, the pore size of MCM-41 could be changed by the control of alkyl chain length of surfactants.

지구 온난화 문제에 대한 국내외 동향과 그 대책에 관한 연구

장원철,이두형,이태진 嶺南大學校 環境問題硏究所 1998 環境硏究 Vol.18 No.1

최근 전세계적으로 지구 온실효과 가스에 의해 야기되는 지구 온난화 현상에 대해 여러 가지 대응방안이 고려되고 있고 특히, 화석 연료의 사용과 관련된 이산화탄소에 의한 지구 온난화와 기후변화는 가장 심각한 문제로 나타나고 있다. 이런 전세계적인 우려는 마침내 기후변화에 대한 정부간 협의체인 COP를 결성시켰고 마침내 지난 1997년 12월 제3차 교토 COP에서 마침내 지구 온난화에 대한 국제적 규제사항으로 배출권거래제도, 공동이행제도, 자발적 협정 내용들이 논의 및 결정되었다. 그러나 이런 국제적인 논의에도 불구하고 국내의 이에 대한 대책은 단지적인 정책 대응에 미치고 있는 실정이다. 그러므로 본 논문은 이런 상황과 결부하여 지구 온난화에 대한 전반적인 상황고찰과 그 대응책으로 지구 온난화 물질 배출에 대한 통계체제 확립, 에너지 절약 및 효율 개선책 마련, 토지의 효율적 이용과 산림관리, 대체에너지 개발과 이산화탄소 이용에 대한 연구개발 확대, 이에 대한 전문인력 확보방안에 대해 그 의견을 개진하여 논의하고자 하였다. This paper gives a consider of recent status and possible countermeasures against global warning caused by gases of the green house-effect. Especially, the global warming and climate change caused by the accelerative emission of carbon dioxide in the atmosphere are the most crucial for human beings. The worldwide anxiety has resulted in the operation of COP (United Nation's Framework Convention of Climate Change) and the 3rd conference on COP was held in the early of December 1997 at Kyoto, Japan. Naturally, several scenarios planned on governmental or political basis was focused on strategic topics, such as the restruction on the amount of consumption of fossil fuels through 'Joint Implementation', 'Eaission Trading', and 'Voluntary Agreements' for the use of carbon sources. Although the climate change issue has been actively discussed in the world, the status of countermove in Korea is only now turning activity and under-develpment situation. This work reviews the conflicts embodied in contemporary debates concerning climate change, technology development, and economic restriction and suggests political strategies for the global warming, such as a construction of monitoring system on gases of green house effect-gas, energy saving, the development of alternative energy, the efficient use of a forest, and rearing of experts.

The electrochemical characteistics of all of tje single crystalline solids that would be used as the solid electrolytes were discussed with the apparatus made to measure the electric spfcific conductivity at various temperatures and with cyclovoltammograph, and measured data were treated by using computer program. It was calculated that the analytical experiment done by the application of A/D converter to the personal computer reduced the analytical error and enhanced the reproductivity by means of the developmental project of computer program. The electrical specific conductivities of Ag solid electrolytes Ag cell were 0.107~0.283 Ohm^-1 cm^-1 at 25℃, and these va1ues were higher than those of the Polycrystalline solids in the same diameter and weight of electrolytes and these values were proportional to temperature and the weight of solid electrolytes. Having measured the cyclovoltammogram of the solid electrolytes, the iodide ions contained in the single crystalline solids were transformed into the iodine and then oxidizing current was increased all at once at tile cathode. The free iodines which had been oxided in range of Ag electrode as cathode were again transformed into iodide ions at the anode and these anodic current appear as the state of reduction.

As personal computers are being developed, most softwares are based on window-based operating systems recently. The programmable logic controllers (PLC's) which are usually operated based on the DOS system should be adapted to the window-based environment in order to have the multi-tasking and flexibility of PLC programs. In this paper, the PLC driving programs which are based on the window-based operating systems are developed for the hardwares in which only DOS-based driving programs are being used currently.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.
