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.

박혜순,신호철,김병성,이가영,최환석,신정아,남윤덕,배상필,천경수 대한비만학회 2003 The Korean journal of obesity Vol.12 No.2

연구배경: 심혈관 질환은 치근 국내에서 그 발생률과 유병률이 급증하여 점점 중요한 국민 건강 문제로 대두되고 있다. 2001년 NCEP ATP Ⅲ에서는 대사증후군에 대해 임상적으로 손쉽게 적용할 수 있는 기준을 제시하면서 심혈관 질환의 주 관리 차상으로 취급하였다. 본 연구에서는 일차의료에서 대사증후군의 유병률을 파악하고, 대사증후군과 관련된 요인을 규명하여 한국인에게 적절한 대사증후군 관리전략을 개발하고자 하였다. 방법: 전국 9개 병·의원 가정의학과에 내원한 20세 이상 80세 미만 성인에서 건강 문제와 무관하게 연속적 조사를 시행하여 총2,134명이 연구에 참여하였다. 대사증후군에 대해서 복부비만은 남자 ≥ 90cm, 여자 ≥ 80 cm으로 하였고 다른 위험인자들은 NCEP ATP Ⅲ의 기준에 따라 정의하였다. 신체 계측, 심혈관 위험인자를 측정하고 생활 습관을 조사하여 대사증후군의 유병률과 관련 요인을 파악하였다. 결과: 일차의료에 내원한 성인에서 대사증루군의 유병률은 남자에서 31.3%, 여자에서 29.5%로 나타났으며, 연령이 증가할수록, 비만도가 증가할수록 대사증후군의 유병률이 높아지는 경향을 나타냈다. 남자에서는 연령, 고소득, 비만, 과다 음주. 과다 흡연이 대사증후군의 관련 요인으로, 여자에서는 연령, 무직, 비만, 심혈관 질환의 가족력, 중등도의 스트레스가 관련 요인으로 나타났다. 결론: 대사증후군은 일차의료에 내원하는 성인 중 비교적 흔하게 나타나는 건강 문제로 약 30%의 유병률을 보였다. 일차의료에서 무증상 성인에게도 허리둘레 측정, 심혈관 위험인자 검사 등 대사증루군의선별검사에 의한 조기 발견과 예방적 차원의 관리가 필요하다고 하겠다 Backgroud: Cardiovascular disease is becoming an important national health issue since its recent increase in incidence and mortality. Despite the significant increase in mortality rate of cardio-vascular disease in Korea, there have been no specific studies concerning metabolic syndrome. The aim of this study was to assess the prevalence of metabolic syndrome and to evaluate the associated factors among adults who visited the primary care. Methods: A total of 2,134 subjects aged 20-79y were recruited from nine primary care clinic. The metabolic syndrome was defined by NCEP ATPⅢ criteria, however, abdominal obesity was assessed by ≥90cm in men and ≥80 cm in women. Anthro-pometric variables and cardiovascular risk factors were measured, and lifestyle factors were assessed through a questionnaire. Results: The prevalence of metabolic syndrome was 31.3% and 29.5% in men and women, respectively. The risk factors associated with metabolic syndrome, in common for both genders, were found to be age, and obesity. Excessive alcohol intake, and heavy smoking were also found to be risk factors of metabolic syndrome in men whereas moderate stress and family history of cardiovascular disease served as risk factors in women. For both genders, greater increase in body weight correlated with higher risk of metabolic syndrome. Conclusion: The prevalence of metabolic syndrome is presumed to be high considering the fact that it is commonly encountered in primary care, therefore a screening program for prevention and management of metabolic syndrome is required.

이경보,김종천,박지혜,이덕배,김종구 한국환경농학회 2004 한국환경농학회지 Vol.23 No.1

하천 수질관리 대안을 제시하고자 동진강에 영향을 가장 크게 미치는 정읍천을 대상으로 2002년 1월부터 2003년 12월까지 점 및 비점 오염원으로부터 수질오염물질의 부하량, 유출 경로 등을 평가하였다. 계절별 수질 변화는 pH 범위가 6.87∼7.53으로 봄의 pH 범위가 컸으 며, EC 농도는 정읍천 중류가 높았으며, 상류유역은 83∼95㎲/㎝ 범위를 나타냈고, 계절별로 가을에 517㎲/㎝로 가장 높았다. BOD의 농도는 상류유역에서 0.61∼1.27 ㎎/L로 Ⅰ급수 수 질은 나타내었으나, 중류와 하류에서는 Ⅲ등급 수준이었다. T-N의 농도는 정읍천 중류 유 역이 6.10∼10.84㎎/L로 가장 높았고, T-P의 농도는 타오염물질에 비해 농도의 편차가 컸으 며, 특히 중류에서 T-P의 농도가 0.41∼0.98 ㎎/L로 높았다. BOD의 배출부하량은 J4 유역에서 553 ㎎/day로 가장 많았고 T-N 발생부화량은 가축, 인 구, 토지이용, 산업의 순으로 컸으며, T-N 배출부하량은 인구 및 산업에 의한 것은 J4 유역, 가축과 토지이용에 의한 부하량은 J5, J6유역에서 높았다. T-N의 유달부하량은 하류 유역에 서 높았으며, T-P의 유달 부하량은 BOD, T-N에 비하여 유달부하량이 낮았고 유달율은 6∼38% 범위를 나타냈다. The influence of pollutant loads on the water quality in Jeongeupcheon of Dongjin river was evaluated from Jan. 2002 to Dec. 2003 for two years. The range of pH in water was 6.87-753. The EC level in upstream ranged from 83 to 95 us/cm with the highest value in autumn. The BOD level in upstream ranged from 0.61 to 1.27 ㎎/L, which would be Ⅰ grade according to water quality criteia by Ministry of Environment, but that in downstream was Ⅲ grade. The average T-N level in midstream range from 6.10 to 10.84㎎/L which was the highest values throughout the stretch of the river. The average T-P levels ranged from 0.41mg to 0.98㎎/L. Jeongeupcheon was suitable for the agricultural usage based upon one year analysis of river water quality. The effluent loads of BOD was high in midstream(J4) with 553 ㎏/day. The major sources of T-N loads were livestock, population, land use, and industry in order. The effluent loads of T-N was high in J4 by population and industry while that of T-N was high in J5 and J6 by livestock and land use. The delivered loads of T-N was high in downstream. The delivered loads of T-P was low as compared with those of BOD and T-N. The delivery ration of T-N ranged from 6 to 38%.

The authors in this manuscript aimed to provide a practical importance of the differential diagnosis of intracranial brain tumor with emphasis on non-neoplastic abnormalities such as cytotoxic edema of the penumbra zone in strokes. The well known SOLs are cerebral ischemic, inflammatory and dysplastic lesions, which intraaxially imitate glioma and other neurogenic tumors. Brain tumor is the one of common intracranial space-occupying lesions (SOLs) on the diagnostic images. However, many non-neoplastic lesions may be indistinguishable from tumors. Especially, early mortality used to be caused by space-occupying hyperacute ischemic stroke, brain edema and herniations. For the retrospective analysis, the authors reviewed the patient charts, the emergency brain Computerized Tomography (CT), magnetic resonance imaging (MRI), clinical stroke history. From Jan. 2003 to Dec. 2003, we managed total 61 acute strokes in ICU. Even though we operated six decompressive craniotomies, nine stereotactic craniotomies including two procedures of brain biopsy and three extraventricular drainage procedures, three patients (4.91%) were finally expired out from the induced herniation and medullary failure by those aggressive strokes. 43 patients (70.5%) were recovered good from stroke attack. 15 patients (24.6%) were improved with residual neurologic deficits. In conclusion, aside from growing efforts of the radiologist to make the early diagnostic impression, the authors suggest that urgent neurosurgical explorations with the pathologic diagnostic decision should be requested to decrease the fatality.

강릉지역 소아에서 비만도와 혈청 지질과의 관련성

심수정,천경수,박혜순 대한비만학회 2003 The Korean journal of obesity Vol.12 No.2

연구배경: 소가 비만이 급속히 증가함에 따라 가장 중요한 심혈관계 위험요인의 하나인 이상지질혈증이 치근 우리나라 소아에서도 중요한 문제로 대두되고 있다. 동맥경화는 아동기부터 시작된다고 알려져있으며 심혈관질환의 고위험인자인 고지혈증의 조기 발견과 치료가 동맥경화성 심질환의 발생을 현저히 감소시킬 수 있다. 본 연구에서는 강릉지역 소아에서 비만의 유병률을 조사하고 혈중지질치와 비만과의 관계를 알아보고자 하였다. 방법: 강릉지역 일개 초등학교에서 7∼12세 사이의 초등학생 1326명 (남자 720명, 여자 606명)을 대상으로 신장 및 체중을 측정하였고 그에 의한 체질량지수를 산출하였다. 혈액 검사는 자발적 참여를 원하는 725명 (남자 393명, 여자 332명)을 대상으로 공복 상태에서 총콜레스테롤, 중성지방 및 HDL-콜레스테롤을 측정하였다. 결과: 해당 성별과 연령에 대한 체질량지수가 85 백분위수 이상인 경우를 비만으로 정의하였을 때 비만의 평균 유병률은 남아 18.9%, 여아 20.6%였다. 남, 녀 모두 비만도가 증가함에 따라 중성지방 및 동맥경화지수는 증가하는 경향을. HDL-콜레스테롤은 감소하는 경향을 나타내었다. 체질량지수가 85 백분위수 이상인 비만군에서 고중성지방렬증과 동맥경화지수 ≥ 4.0의 교차비는 각각 2.3 (1.1∼5.0), 3.7 (1. 2∼11.1)로 유의하게 증가하였다. 결론: 비만한 어린이에서 고중성지방렬증과 동맥경화지수는 독립적인 관련성이 있는 것으로 나타나 동맥경화의 위험을 줄이기 위해 체중 조절이 강조되어야 한다. Background: Atherosclerosis might progress from early life stage if the person is at high risk. Dyslipidemia, one of the most important cardiovascular risk factors, has increased among children in recent years in South Korea. The aim of this study was to evaluate the prevalence of overweight, and to investigate the relation of serum lipid profiles to overweight among children in Gangneung area. Methods: The study subjects were recruited from an elementary school in Gangneung area. Anthro- pometric measurements were examined aged 6-12 years 1326 children (720 boys; 606 girls). Total cholesterol, triglyceride, and HDL-cholesterol were measured in fasting state in 725 children (393 boys; 332 girls) among them. Result: The prevalence of overweight defined as BMI≥285 percentile by gender and age was 18.9% in boys and 20.6% in girls. The prevalence of triglyceride 2130 mg/dL, and atherogenic index (TC/HDL-C) 24.0 among overweight children was significantly higher than that of normal weight children. The triglyceride and atherogenic index increased according to BMI, and HDL-cholsterol decreased according to BMI in both boys and girls. The odds ratio for hypertriglyceridemia, and high atherogenic index in overweight children was 2.3 (1.1-5.0) and 3.7 (1.2-11.1) with adjustment for age and parental BMI. Conclusion: The hypertriglycerdemia and high atherogenic index (TC/HDL-C) was independently associated with overweight among children. Manage- ment of overweight in children is reinforced to decrease the risk of dyslipidemia or atherosclerosis.

Objective : This study was performed to investigate the relationship between social support and quality of life among cancer patients receiving radiation therapy. Matehals and Methods : The data were collected from 98 patients, who were receiving radiation therapy at two university hospitals located in GwangUJu, used by structured questionnaire. For statistical analyses of the association between quality of life and various characteristics, data were analyzed using t-test, ANOVA, Pearson 's correlation, and multiple regression analysis. Results: 1. There were 56(57.1%) males and 42(42.9%) females. Age ranged from 21 to 82 years. The primary sites of cancer were gastrointestinal tract (24.5%), lung (23.5%), breast (21.4%), and head and neck (11.2%) in order. 2. The mean scores of social, family, and medical support were 4.30 0.58, 4.49 0.78, 4.11 0.65, respectively. The score of quality of life was 5.83 1.63 (range: 1.95 ~ 9.05). 3. An analysis of the association between several factors of patients and quality of life showed that the statistically significant factors were age, the presence of distant metastasis, family support, medical support and social support. 4. As a result of the multiple regression analysis, only social support was significant (β=0.932, P=0.02) with quality of life, but age and presence of distant metastasis were not significant. Conclusion : This suggests that quality of life in cancer patients could be improved by strengthening the social support which consists of family and medical support. Further study would be necessary to evaluate separately several aspects of quality of life among cancer patients.
