Non-timber forest products are important crops for farmer`s income and forest management. The objective of this study is to review on the policy of non-timber forest products expanding the share in the Korean forest production. For this, we investigated the achievement of the related policies and the demand and supply outlook. Govrnment has a more concern to enlarge the production quantity rather than to improve the distribution and processing. Korean non-timber forest product industry faces the diminution in export and increase in import. Consequently, we suggest the policy reform to mitigate the investment regulation, to form the production infrastructure and to change to the market-oriented distribution structure.

이경일 ( Lee Gyeong Il ),손철호 ( Son Cheol Ho ) 한국산림과학회 2003 한국산림과학회지 Vol.92 No.6
The purpose of research is to examine direct payment been coming in agriculture under WTO, and to suggest introduction necessity of that in forestry. As a result, direct payment in agriculture is magnified rapidly laying stress on developed country, and also our country has been enforcing that in agriculture since 1997. Under the wicked management status of forestry in Korea, for propelling sustainable forest management and income compensation to nonproductive forest land, it is needed to introduce direct payment in forestry.

본 논문에서는 포터블 뇌파 바이오피드백시스템을 위한 전치증폭부 및 디지털 신호처리부의 하드웨어 구현에 대한 연구를 수행하였다. 뇌파의 특성을 고려하여 외부 잡음을 제거할 수 있는 뇌파 획득용 전치증폭부를 구현하였다. 측정된 뇌파에는 안전도, 근전도, 심전도 등의 신호들이 포함되어 있으며 이들은 뇌파 분석에 방해가 된다. 따라서 이러한 신호들을 제거하기 위하여 적응여파기 알고리듬을 수행하고 전치증폭부를 실시간으로 구동하는 디지털신호처리부를 구현하였다. 시뮬레이션 파형과 실제 뇌파를 적용한 실험결과를 통하여 개발된 시스템의 성능을 확인할 수 있었으며 휴대형 뇌파 바이오피드백 시스템에 적용 가능함을 확인하였다. In this study, we carried out a study for implementation of the pre-amplifier and the digital signal processing part for the potable EEG biofeedback system. As we consider characteristics of the EEG signal, we designed the pre-amplifier to obtain the EEG signal to be reduced noise signal. Because the EEG signal include EOG, EMG, ECG signals etc, it is difficult to analyze of the EEG signal. Therefore, we developed DSP board and operation program which was embed the LMS adaptive filter algorithm and operate with the pre-amplifier in the real time. The simulation signal and pure EEG signal is used in the experiment. As the result, we confirmed good efficiency of developed system and possibility of application to the portable EEG biofeedback system.

이경일(Lee Gyeong Il),정명수(Jeong Myeong Su),정진영(Jeong Jin Yeong) 한국사회체육학회 2003 한국사회체육학회지 Vol.19 No.1
The research investigates the effect of extracurricular activities to self-esteem and is classified into three factors: -physical factors, artistic factors, and intellectual factors. They were analized by the effects of self-physical, self-effect, self-esteem and self-achievement. The children who have extracurricular activities more than 2 times a week(each at least 50 mins after school). We used a self-physical survey report, a self-effect survey report and a self-esteem survey report as the method of research. However, we excluded some insincere survey datas such as double entrys or blank entrys, only secure data was included and analized by SPSS 10.0. We reach some conclusions from the collected datas used by a standard variance, a analysis of reliability, multiful response cross-tab, one-way anova, correlation, multiful regression followed as below; 1. The school childrens extracurricular activities on participation characteristics shows that depending on sex, family income, the intellectual activities, artistic activities, physical activities follow the academic level of the children in school. Also it shows that the physical activities of school children decrease as the increase in grade. 2. The psychological characteristics follow the dynamic statistic of population and the academic year, it shows the small contrast that is: first, the self-esteem depends on the family income and the academic year. second, the self-effect depends on sex, family income and the academic year. third, the self-physical depends on family income and the academic year. fourth, the self achievement depends on family income, parents academic background(especially mother`s) and the academic year. 3. The psychological characteristics follows the form of activities after school. It shows the small contrast in self-effect, self-physical and self-achievement. 4. We found that there is a high mutual relationship between the psychological characteristic factors. The self-esteem was getting higher as the children improved in self-physical, self-effect, and self-achievement through the extracurricular activities after school.

목 적 : 우리나라 소아 만성신부전 환자의 빈도와 원인, 결과, 현재까지의 치료실태 등 임상양상을 전국적으로 파악하여 소아 만성신부전증에 대한 이해를 돕고 이에 대한 앞으로의 치료방침을 세우는데 있다. 방 법 : 전국 소아과 수련병원을 대상으로 1990년 1월부터 1999년 12월까지 만 10년간 만성신부전 환자에 대한 자료를 설문지를 통해 수집하여 원인질환, 만성신부전시의 연령 및 혈청크레아티닌치, 말기신부전시의 연령 및 혈청크레아티닌치, 치료실태 등을 분석하였다. 결 과 : 최근 10년간의 소아 만성신부전 환자는 401명으로 남아 254명, 여아 147명이었으며 1년에 소아인구 백만명 당 3.68 명의 만성신부전 환자가 발생하였다. 만성신부전시의 연령은 5세 미만은 22$\%$, 5세에서 10세는 28$\%$, 10세에서 15세는 50$\%$ 이었다. 원인질환으로는 사구체신염 (36$\%$), 만성 신우신염 (21$\%$), 신이형성 및 신형성부전 (9$\%$) 순이었고 단일 신질환으로는 역류성 신병증 (16$\%$), 소상 분절성 사구체경화증 (11$\%$) 등이 흔하였다. 말기신부전에 이른 284명중 282예에서 신대체요법이 시행되었다. 일차적으로 선택된 신대체요법은 혈액투석이 42$\%$. 복막투석이 35$\%$, 신이식이 23$\%$ 이었고 말기신부전 환아 중 159명 (56$\%$)에서 신이식이 시행되었다(1차 신이식 159명, 2차 신이식 2명). 평균 신대체요법의 기간은 $3년\;1개월{\pm}2년\;8개월$이었고 신대체요법을 받은 환아의 생존률은 88.7$\%$ 이었다. 결 론 : 우리나라 소아 만성신부전의 가장 흔한 단일 신질환은 역류성 신병증으로 조기 진단 및 치료로 만성신부전으로의 진행을 예방할 수 있는 질환이었다. 소아 말기신부전 환자에서 일차적으로 선택한 신대체요법은 혈액투석, 복막투석 및 신이식이 각각 $42\%,\;35\%,\;23\%$ 이었고 궁극적으로 신이식을 시행받았던 환아는 전체환자의 56$\%$로써 투식 및 신이식이 우리나라 소아 말기신부전 환아의 주된 치료법으로 자리잡았음을 알 수 있었다. Purpose : We analyzed the demogaphic data md clinical course of Korean children with chronic renal failure (CRF) observed between 1990 and 1999. Patients and Methods : Questionnaires were mailed to all children's hospitals ail through the country. We asked for primary renal disease age and serum creatinine levels at first presentation with CRF and end-stage renal disease (ESRD), and modes of renal replacement therapy (RRT). Results : 401 children (254 boys, 147 girls) with CRF, defined as a permanent increase of serum creatinine above 1.2 mg/dl for at least 3 months or until death, were identified. This represents an incidence of 3.68 per million child population per year. Of these patients, 22$\%$ on younger than 5 years, 28$\%$ 5 to 10 years and 50$\%$ 10 to 15 year. Eight five $\%$ of the patients could be classified with a primary renal disease. The most frequent cause is glomerulonephritis (36$\%$), followed by chronic pyelonephritis (21$\%$), renal hrpo/dylplasia (9$\%$), and hereditary nephropathies (7$\%$). Reflux nephropathy (16$\%$) was the most common single cause of CRF. ESRD was reached in 70$\%$ of all patient. 99.3$\%$ of these started RRT. Hemodialysis (HD, 42$\%$), peritoneal dialysis (PD, 35$\%$) and transplantation (TP, 23$\%$) were performed as the initial mode of RRT. A total of 161 TPs were performed (159 first grafts, 2 second grafts). A total of 32 patients died. The main causes of death were dialysis related complication in HD patients and infections in PD patients. Survival rate on any form of RRT was 88.7$\%$ during the mean follow-up period of 37 months. Conclusion Major efforts should be directed toward earlier diagnosis and treatment of reflux nephropathy to prevent occurrence of Of. Dialysis and TP have now become well accepted forms of treatment in Korean children with ESRD.
