We developed the educational purpose mobile application, named "Wild Flowers of Bukhansan National Park (version 1.0)", aiming for easy identification of wild flowers for students and visitors in the park. When visitors find a flower or part of plant in the park, visitors can search for its name utilizing the pictures and characters provided in their own smartphone mobile devices or tablet PCs. The application provides pictures of wild flowers in the park and character-based searching system based on 12 diagnostic features (e.g., growth form, leaf arrangement, flower symmetry, petal color, petal number, sepal number, etc). We adopted the complete floristic survey of Chung and Lee (1962) and added species that we confirmed their distribution in the park during the development of this application. In summary, number of vascular plants in this park was estimated to be 428 taxa including 100 families, 280 genera, 327 species, 1 subspecies, 50 varieties, and 5 formas. We provided a total of 588 pictures representing 358 taxa and each taxon includes multiple pictures in many cases. Included identification quizzes can be an efficient educational tool as well as fun activity for students and visitors who are learning plant species in Korea. Our next step will include GPS function in the application for indicating visitor's location and for providing previously reported sites of the species that we interested in the map of the park. The future application which includes GPS function will be a valuable tool for the monitoring of rare plants, plant researches related to the climate changes, etc. We currently provide Korean iPhone version only, and English version and both of android versions will be serviced soon.

A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

This study was conducted to examine aspects of middle and high school students' drinking and smoking with analysis of related factors. The subjects of this study was 540 students in Kyungbuk Province. Data were collected from July, 2002 to September, 2002. The results of this study can be summarized as follows. 1. 43.6% of the boy students experienced smoking, while 12.2% of the girl students experienced it. 5.3% of the students at academy schools experienced smoking, while 44.7% of the students at vocational schools experienced it. 11.4% of the middle school students experienced smoking, while 33.9% of the high school students experienced it. 15.5% of them who lived in towns or villages experienced smoking and 38.3% of them who lived in small or medium sized cities experienced it.37.5% of the students who belonged to the lower economic class experienced smoking and 20.7% of the students who belonged to the upper economic class experienced it. 24.0% of the students who belonged to the middle economic class experienced it. It appears that the respondents showed significantly different smoking experience rates by gender, school types, grades, the number of family members, residences, and economic classes. 2. 14.5% of the respondents who lived with grandparents and parents experienced smoking and 26.5% of them who lived with parents experienced it. The smoking rate was significantly high in the groups of having one-parent, being unsatisfied with family life, making poor grades in studies, and having the father or the mother working as a salesperson. 3. 45.3% of the respondents who were unsatisfied with family life experienced smoking. The smoking rate of the respondents who were unsatisfied with it was significantly higher than that of the other groups. On the other hand, the smoking rates were not significantly different by daily life, schoolmate relation, health condition, and feeling stress. 4. According to smoking rate by frequency of drinking, 16.4% of the respondents who drank less than once a month smoked and 54.8% of them who drank more than twice a month smoked. The more frequently they drank, the higher their smoking rate was. Those who did exercise displayed significantly higher smoking rate than those who did not do exercise. Among the rates of the respondents' agonies, family disharmony was 50.5% and love problem was 39.2%. Economic condition preblem was 34.6%. It appeared that smoking was most influenced by the family disharmony. 5. The factors significantly influencing smoking experience were gender, school grade, schoolmate relation, score in studies, and exercise. From above results, it can be concluded that the students' smoking is a serious problems which can be resolved by simple approaches because it is interrelated complicatedly with gender, grade, family, school, etc. Schools, related organizations, and the government must closely work together to maximize the effectiveness of policy implementation concerning the smoking and drinking problem of the middle and high school students.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

박익수,이정근,노양호,김동우,김우형,이희철 大韓顎顔面成形再建外科學會 2003 Maxillofacial Plastic Reconstructive Surgery Vol.25 No.2

Olfactory neuroblastoma is an uncommon malignant tumor(just over 300 cases have been reported in the medical literature by 1996)arising within the nasal cavity. This tumor has a neuroectodermal cell origin and is believed to specifically arise from the olfactory epithelium. The tumor was ftrst decribed in the French medical literayure by Berger and associates in 1924 by the name esthesioneuropitheliome olfactif. The english version of this term is esthesioneuroblastoma, and current medical literture uses this name interchangeably with olfactory neuroblastoma. We experienced a case of olfactory neuroblastoma in the mxillary sinus. We treated this patient with tumor resection, chmotherapy and radiotherapy. And now, the patient has been following up for 2years 6month, but olfactory neuroblastoma is very rare. SO we report this case with a review of literature.

해부-신경생리학적 Monitoring을 통한 뇌중심 영역수술의 고찰

박명찬,박철형,김형일,이정청,김동찬,송희선 대한신경외과학회 1994 Journal of Korean neurosurgical society Vol.23 No.6

In the surgery of central area, idenwg the motor cortex in front of central sulcus is imperative to prevent loss of motor function. Twenty five patients with tumors or intractable epilepsy near the central sulcus were operated on at the Department of Neurosurgery of Chonbuk National University Hospital, from September. 1991 to December 1993. An estimated localization of lesions was performed with Callosal Grid System, which is a methodolgy made available by the development of high quality of magnetic resonance imaging, digital subtraction angiography and high resolution computerized tomography. This system allowed us to be oriented to the motor cortex as well as permitted assessment of the extent of resection. This was further delineated by direct electrical stimulation, which confirmed the functional motor cortex and made it possible to maximized the tumor resection near and in the motor cortex The combination of direct cortical stimulation (functional mapping) and the use of the Callosal Grid System (anatomical mapping) allowed us to idene the spatial relationship between them as well as to maximize the tumor resection in most cases without injury to the central area, so that the better outcome is guaranted.
