연골육종은 비교적 서서히 자라며 늦게 전이하는 악성 연골 종양으로 알려져 있다. 골 연골종에서 발생한 속발성 연골육종은 발생빈도는 드물며 타부위로의 전이가 적고 악성도가 낮은 경우가 많아 적합한 수술적 치료로서 좋은 예후를 보이는 것으로 보고되고 있다. 본 동국대학교 정형외과학 교실에서는 우측 대퇴골 원위부 골간단부에 생긴 고립성 골 연골종에서 이차적으로 발생한 연골육종을 치험한 바 문헌고찰과 함께 보고하는 바이다. A case of Secondary Chondrosarcoma Arising from Solitary Osteochondroma of the Distal Femur Department of Orthopaedic Surgery, College of Medicine, DongGuk University Phil Hyun Chung M.D., Jung Su Hwang M.D., Suk Kang M.D., Yang Mln Kim M.D., Hyung Ho Oh M.D., Dong Ju Chae M.D., Jong Pil Kim M.D. Chondrpsarcoma is a malignant cartilage-forming tumor that grows slowly and metastasis of this tumor occurs in late stage. Secondary chondrosarcomas arising from a solitary osteocartilaginous exostosis are rare and those have a better prognosis than other chondrosarcomas, and they rarely metastasize. We present our experience with a case of secondary chondrpsarcoma arising in solitary osteochondroma of distal metaphysis of right femur with clinical details.

Tsutsugamushi disease is an acute febrile illness caused by Orientie. tsutsugsmushi. It is characterized by fever, myalgia, lymphadenopathy, and rash. And it can be easily diagnosed by characteristic eschar and serologic testing. Nearly all of the patients with tsutsugamushi disease improve with antibiotics such as doxycycline. However, the fatality rate of untreated cases is seven to ten percent. Splenic infarction is not common disease which is caused by occlusion of the main splenic artery or any of its branches. It is mainly caused by emboli that arise from cardiovascular disease, but sometimes by regional thrombosis associated with leukemia, myeloproliferative disorder, sickle cell anemia, pancreatitis, splenic torsion and septicemia. We experienced one case of tsutsugamushi disease with splenic infarction, which was improved after doxycycline treatment finished.

소비자 중심의 정보정책에 관한 연구

오종근,임광현 全北行政學會 2001 全北行政學報 Vol.15 No.1

각종 정보(통신)기술의 급속한 보급을 통한 한 국가의 정보화사회로의 진입은 전통적인 사고와 생산방식에서 탈피하여 민간부문의 경영방식 뿐만 아니라 국가행정운영 전반에 걸쳐 산업사회와는 판이한 새로운 패러다임의 요구를 촉발시키는 계기가 되었다. 특히 문자, 음성, 화상, 그래픽 등 각종 정보가 기존의 아날로그 방식에서 디지털 방식으로 급속히 전환됨에 따라 정보의 처리가 용이해지고, 양방향 통신이 가능해지면서 사용자 욕구를 충족시키기 위하여 정보전달, 교육, 영화, 쇼핑, 오락, 의료 등 분야에서 다양한 인터렉티브(interactive) 멀티미디어 서비스가 본격화되고 있다. 민간 부문에서는 BPR, 전사적 자원관리(ERP), 아웃소싱, EDI/CALS/EC 등의 새로운 경영전략을 도입하여 기업의 구조와 업무 프로세스를 정보화 시대 요구에 걸맞게 변화시키고 있다. 또한 CIO(정보담당중역)를 중심으로 E-COMMERCE 시대에 부응할 수 있는 지식경영시스템(KMS)구축에도 전사적 관심을 보이고 있다. 이러한 시대적 환경에 부응할 수 있는 소비자 중심의 정보정책을 펴 나가기 위해서는 어떤 면에 특히 관심을 가져야 되는지를 다루고자 하였다. 연구결과 소비자 지향적인 정보정책을 시행하기 위하여 정보에 있어서의 정부의 역할을 크게, 기업에 의한 정보제시요구, 정보의 정확성보증, 정보의 직접기대 및 상담서비스의 역할로 분류하여 이들에 대한 시사점을 제시했다.

This is a study to develop the obervations and experimental materials for the elementary school 4th.5th.6th grade science curriculum that are carried on effect from this year. The materials which teachers do and the teachers and students can make, by themselves, are as follows: 1) In the field of biology for 4th.5th and 6th grade, 11 kinds of plant observating materials were cultivated. 2) In physics field of sixth units in the text book for 4th.5th and 6th grade, 10 kinds of implements were developed: electric circuit, moving of heat, expansion of heat and body, solute, movement of Earth and Moon, eaergy of Water and Wind.

There is a rising hobby in the COVID-19 pandemic era. At this point, camping accidents are also occurring a lot as more people are camping in cars and outdoors. Most of the casualties among them are carbon monoxide poisoning accidents. Therefore, to prevent carbon monoxide poisoning, we measured with an Arduino board using a "DHT22" sensor and an "MQ7" sensor to know temperature, humidity, and carbon monoxide levels, and then printed it out on LCD after storing it in Raspberry Pi database. Therefore, it is implemented through 3D printing on the appearance modeled directly to the actual user.

Objectives : The aim of this study was to compare endogenous plasma lithium concentrations among schizophrenic patients classified by DSM-IV subtype and control groups and to investigate the correlation of endogenous plasma lithium concentration and psychotic symptoms in schizophrenia. Methods : Schizophrenic patients were selected among psychiatric inpatients without lithium medication and then classified by DSM-IV schizophrenia subtype, Schizophrenic patient groups were composed of 15 disorganized type, 15 paranoid type and 15 undilferentiated type schizophrenic patients. The control group was composed of 15 healthy subjects without any psychiatric disease,Endogenous plasma lithium concentrations were estimated by inductively coupled plasma atomic emission spectrometer. The psychotic symptoms in schizophrenic patients were classified as positive symptoms, negative symptoms and disorganized symptoms according to andreasen classificationl about SANS and SAPS items. Endogenous plasma lithium Con-centration among three subtypes of schizophrenia and control group was compared, and correlation between endogenous plasma lithium concentrations and psychotic symptoms was examined. Rcsults : 1) Schizoprenic patients showed higher endogenous plasma lithium concentration than control groups (p=0.033). Endogenous plasma lithium concentrations were significantly different among three subtypes of schizophrenia (p=0.001). Compared with the control group, disorganized type showed higher endogenous plasma lithium concentration, but paranoid type and undifferentiated type were not significantly different. 2) Disorganized symptoms correlated with endogenous plasma lithium concentration (r=0.416, P=0.004), but negative symptom and positive symptom did not significantly correlate with endogenous plasma lithium concentration (r=0.202, P=0.184. r= -0.216, P=0.155). Conclusion : These results suggested that schizophrenic patients with disorganized symptom show the differences in utilization or distribution of endogenous lithium.

This study was performed to know LAS concentration in the small urban stream and estimate the LAS removal efficiency when apply to natural purification method with variable media. When we used gravel and concrete as media, the average LAS concentration of influent was 819.7㎍/ℓ (112.0 ∼ 1671.0 ㎍/ℓ). The average LAS concentration of effluent gravel media reactor was 58.5 ㎍/ℓ (0 ∼ 158.4 ㎍/ℓ) and average removal efficiency was 93.8%. The average LAS concentration of effluent concrete media reactor was 33.1 ㎍/ℓ (0 ∼ 136.8 ㎍/ℓ) and average removal efficiency was 96.1%. And when we used tire and scrubber, the average LAS concentration of influent was 693.7 ㎍/ℓ (241.5 ∼ 1330.3 ㎍/ℓ). The average LAS concentration of effluent tire media reactor was 88.4 ㎍/ℓ (47.8 ∼ 131.8 ㎍/ℓ) and average removal efficiency was 83.9%. The average LAS concentration of effluent scrubber media reactor was 26.1 ㎍/ℓ(0 ∼ 58.9 ㎍/ℓ) and average removal efficiency was 95.3%.
