A primary central nervous system lymphoma(PCNSL) is defined as a lymphoma limited to the cranial-spinal axis without systemic involvement. PCNSLs were formerly very rare, only 0.5∼ 1.2% of all intracranial neoplasms, and were usually associated with acquired immuno-deficiency syndrome(AIDS) and other immune-compromised states. Recently, there has been a clear rise in the incidence of this disease among normal individuals. We describe a 77-year-old female with hyponatremia who presented with a confused mental state. Computed tomography(CT) of the brain demonstrated a suprasellar mass with enhancement. We evaluated the basic hormonal studies and the magnetic resonance imaging(MRI). A ventricular biopsy was done, and the result was a diffuse, large, B-cell-type malignant lymphoma. She presented panhypopituitarism and partial central diabetes insipidus. She received chemotheraphy and was discharged in an improved condition. We report a case of panhypopituitarism due to PCNSL and give a review of the literature.

The vision system model used for this study involves the six parameters that permits a land of adaptability in th relationship between the camera space location of manipulable visual cues and the vector of robot joint coordinates is estimated in real he. Also this vision control method quires the number of cameras to transform 2-D camera plane from 3-D physical space, and be used irrespective of location of cameras, if visual cues are displayed in the same camera plane. Thus, this study is to investigate the optimal number of cameras used for the developed vision control system according to the change of the number of cameras. This study is processed in the two ways : a) effectiveness of vision system model b) optimal number of cameras. These results show the evidence of the adaptability of the developed vision control method using the optimal number of cameras.

The purpose of this study is to develop scale items to measure servicescape of ski resort, to measure servicescape of ski resort to use them, and to find out relationships among servicescape, customer satisfaction and Behavioral intentions. Hypotheses were developed from reviewing the existing literature and tested empirically. The survey, based on questionnaire, was conducted in ski resort. The data were analyzed using SPSS 10.0 and structural equation model by LISREL 8.51. As a result of factor analysis on servicescape of ski resort, 6 factors were extracted and titled "lift", "ski slope", "facilities layout", "safety facilities", "other facilities", and "ski equipments". The results of the study show that servicescape of ski resort has a positive relationship with customer satisfaction, but has not relationship with behavioral intention. The customer satisfaction has a positive influence on behavioral intentions.

풍동실험을 위한 LabVIEW 응용 온라인 계측시스템의 개발

김봉근,장성태,이경용,박운진 한국기술교육대학교 2004 論文集 Vol.10 No.2

On-line measurement systems were newly developed for the performing effective wind tunnel experiments by utilizing the LabVIEW(Laboratory Virtual Instruments Engineering Workbench) system. As a result, instead of post-data-processing procedures based on Fortran programming which was commonly adopted in conventional measurement systems, wind tunnel experiments can be carried out on window-based PC operating systems and thus much time and effort required in analyzing fluid flow field can be successfully reduced. Furthermore, by utilizing the web publishing tool which is provided by the LabVIEW, it is possible to monitor and to control each measurement step via internet web pages from the remote area other than the laboratory in which experiments are carried out.

Designed values are compared with values of measured data of oval shape piston and allowable range and deviation are printed out by using this system. Thereafter, it is able to measure ovality precisely and to estimate itw quality rapidly.

해면 정맥동 혈전증(Cavernous Sinus Thrombosis) 치험례

김경원,김용관,장명진,장현석 大韓顎顔面成形再建外科學會 1995 Maxillofacial Plastic Reconstructive Surgery Vol.17 No.4

Cavernous sinus thrombosis is one of the major complications of abscesses of the maxillofacial region. The initial symptoms of CST are usually pain in the eye and tenderness to pressure. this is associated with high fluctuating fever, chills, rapid pulse, and sweating. Venous obstruction subsequently causes edema of the eyelids, lacrimation, proptosis, chemosis and retinal hemorrhages. Blindness is sometimes an accompaniment of cavernous sinus thrombosis when the infection also involves the orbit. There is also cranial nerve involvement (oculomotor, troclear, abducence) and ophthalmoplegia, diminished or absent corneal reflex, ptosis, and dilation of the pupil occur. The terminal stages bring signs of advanced toxemia and meningitis. Infections of the face can cause a septic thrombosis of the cavernous sinus. Furunculosis and infected hair follicles in the nose are frequent causes. Extractions of maxillary anterior teeth in the presence of acute infection and especially curettage of the sockets under such circumstances can cause this condition. The infection is usually staphylococcal. The inflection may spread directly through the pterygoid plexus of veins and the pterygomaxillary space and then ascend into the sinus or it may spread directly from the pterygopalatine space to the orbit. This is possible because of the absence of valves in the angular, facial, and ophthalmic veins. The treatment is empirical antibiotic therapy followed by specific anbibiotic therapy based on blood or pus culture. The inflection usually involves one side, however, it may easily spread to the opposite side through the circulus sinus. Unless it is treated early, the prognosis is poor even in this doses. Occasionally the antibiotics will not adequately resolve the septic thrombus, and death ensues. the use of anticogulants to prevent venous thrombosis has been recommended, but the efficacy of such therapy has not been substantiated. Surgical access through eye enucleation has been suggested. We report a case which demonstrates cavernous sinus thrombosis by the infection after the functional neck dissection and the intraoral reconstruction with auriculomastoid fascio-cutaneous island flap.

In other to know the characteristics of the air sea heat flux at on the coastal of Jeju Island. when there was a snowfall in winter. It is used as the basic data are Automatic Synoptic Observation System(ASOS) compiled by Jeju Regional Meteorological Office(JRMO) from 1993 to 2002, and SST data derived from National Oceanographic Research Institute(NORI) and National Fisheries Research & Development Institute(NFRDI) observations. the heat flux of the coastal of Jeju Island shows its maximum in January(latent heat flux : 35Wm^(-2) , sensible heat flux : 85Wm^(-2)), and shows its minimum in July(latent heat flux : -l3Wm^(-2), sensible heat flux : -5Wm^(-2)) the more the temperature gap between the air and SST is large and the stronger a wind is, the more it supplies the heat from the sea to the air. it shows that the north-western areas is about three times higher than other areas in Jeju Island. when fresh snow cover is 0.0∼0.9 ㎝, the mean bowen's ratio(for 1993∼2002) is 0.63∼0.67. when it is 1.0∼4.9 ㎝, the mean bowen's ratio(for 1993∼2002) is over 0.72 or more. When bowen's ratio increased upto 0.63∼0.80. fresh snow cover is increased gradually, therefore, it is researched the there is proportion between the fresh snow cover and the bowen's ratio.

With the development of telecommunication technology, and with combination of computer and communication, a new field, which is called a customer care call center , has been created. In the past, the customer center was just passive in the way that their role was just answering to the customers' questions. However, now this has been changed to be active and positive for fulfill customers' satisfaction. Therefore, not only enterprises, but also public institutions and government agencies are having customer care centers as one of methods to maximize customer service. Also, the role of customer care center is extended to marketing activities. The actual proof study on training of call center employees and the transfer of the training to the work has been practiced for this research. The findings of this research are summarized as follows ; first, building factors of learning organization is positively associated with the transfer of training, second, organizational characteristics has moderating effects between building factors of learning organization and training effectiveness. 본 연구는 콜센터 종사자를 대상으로 학습조직 구축요인과 조직특성의 교육훈련 효과성 관계를 알아보기 위하여 학습조직구축요인, 조직특성, 교육훈련 효과성의 개념과 이론을 정리하였고, 연구모형과 가설을 통해 실증분석결과를 제시하였다. 연구결과 학습조직 구축요인이 교육훈련 효과성에 영향을 미치는 것으로 분석되었고, 양 관계에 있어서 조직특성이 부분적으로 조절효과가 있는 것으로 나타났다.
