Background : For cultivation of varieties of ginseng, the pure line selection method, which is to select the best among those cultivated in farms for pedigree breeding, replicated yield trials and regional adaptation trials before registering as a new variety, is widely used. Although there are 25 registered varieties of ginseng in Korea, the quality of ginseng is declining together with the amount of harvest being decreased by 15 - 20% due to the heat injuries and diseases from the warming & abnormal climate. Thus, the needs for development of disaster-resistant varieties with better chances of surviving through high temperature, salts and disease are increasing. Therefore, this study is to cultivate disaster-resistant varieties among those selected for their disaster tolerance and salt tolerance through regional adaptation trials. Methods and Results : As a result of examining the growth characteristics of the selected 2 - 5 year old varieties used in the study, among the 5-year old crops, Goryeo 4 and Eumseong 5 showed superior growth in both above and below aerial parts, and among the 4-year old crops, Eumseong 11 and Cheonryang showed superior growth while the growth in the below aerial parts were satisfactory in the order of Cheonryang > Eumseong 10 > Eumseong 11 > Eumseong 9. Among the 3-year old crops, the most superior growth in both above and below aerial parts was observed in Eumseong 14 with the weight of the below aerial part, root diameter and taproot length at 13.8 g, 11.8 ㎝ and 6.2 ㎝ respectively. Among the 2-year old crops, Eumseong 10 showed the most superior growth in both above and below aerial parts. Conclusion : Based on the above results, Goryeo 4 and Eumseong 5 among the 5-year old crops, Eumseong 11 among the 4-year old crops, Eumseong 14 among the 3-year old crops and Eumseon 10 among the 2-year old crops showed the most superior growth among the selected varieties. The growth characteristics of both above and below aerial parts in each year will continuously be monitored.

연구배경:당뇨병 환자에서 혈액응고 및 섬유소용해 체계의 이상경향이 있어 그 결과로 여러 혈관합병증의 발생위험이 높다는 사실은 널리 알려져 있다. 그 기전은 아직 확실히 밝혀지지 않았으나, 고혈당으로 인한 혈장 단백질들의 비효소성 당화작용이나 산화성 스트레스로 인한 유리 라티칼 작용으로 응고항진이나 섬유소용해 활성의 저하를 유발하는 것으로 생각되고 있다. 최근 응고 및 용해인자와 그 억제자의 복합체들의 증가가 이 상태를 비교적 예민하게 반영한다고 알려져 있다. 방법:본 연구에서는 당뇨병 환자 101명과 정상 대조군 20명에서 혈장내 thrombin­antithrombin complex(TAT)와 plasmin­α₂­plasmin inhibitor complex(PIC)를 측정하여 비교하고, 당뇨병 환자에서 미세혈관 합병증과 대혈관합병증의 유무에 따른 차이와, 이미 혈관 질환의 위험인자로 알려져 있는 인자들간의 상관성을 알아보고자 하였다. 결과:1. 환자의 분포를 살펴보면 혈관합병증이 있는 군은 85명, 혈관합병증이 없는 군은 16명이었고, 평균연령은 각각 57.9±14.1세, 49.9±16.6세로 혈관 합병증이 있는 군에서 더 나이가 많았고, 체질량지수는 23.2±3.4㎏/㎡, 24.1±3.4㎏/㎡로 두 군간 유의한 차이는 없었다. 또 두 군간의 혈압 및 HbA1c, 공복혈당 및 인슐린과 C­peptide, 총 콜레스테롤, 중성지방, HDL­콜레스테롤, Lp⒜는 유의한 차이가 없었고, 미세혈관합병증이 있는 군에서 당뇨병의 유병기간이 길었다. 2. TAT 및 PIC의 농도는 정상 대조군에서는 2.8±1.2 ng/mL, 240.4±69.7 ng/mL이었고, 당뇨병 환자군에서는 9.5±22.6 ng/mL, 472.2±258.7 ng/mL이었다. TAT와 PIC 모두 당뇨병 환자군에서 정상 대조군에 비해 유의하게 증가되어 있었고(p<0.001), TAT/PIC ratio는 두 군간 차이가 없었다. 3. 당뇨병 환자의 혈관합병증에 따른 TAT 및 PIC, fibrinogen 농도는 합병증이 없는 군은 각각 4.1±2.4ng/mL, 362.2±272.0ng/mL, 322.7±102.4mg/mL으로 PIC와 fibrinogen의 증가를 보였으나, 연령을 보정한 후에는 통계학적 유의성은 없었다. 또 대혈관 합병증군에서는 각각 6.0±4.9 ng/mL, 507.4±321.6 ng/mL, 427.1±194.7 mg/dL이었으며 미세·대혈관 합병증군에서는 10.4±6.4 ng/mL, 484.8±269.7 ng/mL, 388.4±132.4 mg/dL으로 TAT의 증가를 보였으나 역시 연령을 보정한 후에는 통계학적 유의성은 없었다. 4. 미세혈관합병증군에서 HbA1c(>8%)가 높은 군의 PIC 농도가 유의하게 높았고(p=0.049), 대혈관합병증군에서 HbA1c(>8%)가 높은 군의 총 콜레스테롤 농도가 유의하게 높았다(p=0.042). 5. 총 당뇨병 환자군에서 PIC는 fibrinogen과 HbA1c와 양의 상관관계를, BMI와 음의 상관관계를 보였으며(r=0.47, 0.31,-0.25), 혈관 합병증이 없는 당뇨병 환자군에서만 TAT는 HbA1c와 양의 상관관계를 보였다(r=0.67). 결론:이상의 결과에서 혈장 TAT 및 PIC 농도는 당뇨병 환자에서 정상 대조군에 비해 의미있게 증가되어 있었고, 당뇨병 환자군에서는 연령의 증가와 유병기간이 혈액응고항진 및 용해의 장애에 큰 역할을 함을 알 수 있었으며, 총 당뇨병 환자군에 PIC와 HbA1c와 양의 상관관계를, BMI와 음의 상관관계를 보였으며 혈관 합병증이 없는 당뇨병 환자군에서만 TAT는 HbA1c와 양의 상관관계를 보였다. 따라서 당뇨병 환자에서 혈액응고 및 용해의 장애가 동반되어 있다고 볼 수 있으며, 혈장 TAT 및 PIC는 혈관합병증으로의 진행을 예측하는 지표로서 유용하리라 생각된다. 또 혈당조절정도와 상관성이 있으므로 혈당조절후에 추적검사를 시행하여 합병증의 예방이 가능한지 추후 연구가 필요하리라 생각된다. Background : Abnormality of coagulation and fibrinolystic system is known as a predisposing factor of vascular complication in diabetes. Although the pathogenesis is not well known, non-enzymatic glycation reaction and the increase in production of free radicals due to an increased oxidative stress may be linked to the hypercoagulibility and hypofibrinolytic activity. As indices of abnormality in coagulation and firinolysis in peripheral blood, plasma thrombin-antithrombin Ⅲ complex (TAT) and plasmin-α_2-plasmin inhibitor complex (PIC) were measured. The purpose of this study was to clarify whether hypercoagulability exists in diabetic patients with or without vascular complication. Methods : In our study, we measured plasma thrombin-antithrombin Ⅲ compelx (TAT) and plasmin-α_2-plasmin inhibit or complex (PIC) in 101 diabetic subjects and 20 controls. Comparing TAT and PIC levels in diabetic microvascular complication group, diabetic macrovascular complication group and controls, we examined correlation between risk factors associated with diabetic vascular complication. Results : 1. The group with diabetic vascular complication was older than group without complication. There was no significant difference in BMI, blood pressure, HbA_ic, blood sugar level, insulin, C-peptide, serum creatinine, total cholesterol, triglyceride, HDL-cholesterol, Lp (a) between two groups. The group with diabetic microvascular complication had longer duration of diabetes. 2. Concentration of TAT and PIC were 2.8±1.2 ng/ mL, 240.4±69.7 ng/ mL in controls and 9.5±22.6 ng/ mL, 472.2±258.7 ng/ mL in diabetic patients, respectively. TAT and PIC were significantly higher in diabetic patients than in control (p<0.001). But TAT/PIC ratio was no significant difference between two groups. 3. In diabetic patients, concentration of TAT and PIC and fibrinogen were respectively 4.1±2.4 ng/ mL, 362.2±272.0 ng/ mL, 322.7±102.4 mg/ dL in group without vascular complication and 5.3±4.1 ng/ mL, 529.5±258.7 ng/ mL, 374.9±106.2 mg/ dL in group with microvascular complication, which group had increase in PIC and Fibrinogen but no significance after correction of age. Concentration of TAT and PIC and Fibrinogen were 60.±4.9 ng/ mL, 507.4±321.6 ng/ mL, 427.1±194.7 mg/ dL in macrovascular complication, and 10.4±6.7 mg/ mL, 484.8±269.7 ng/ mL, 388.4±132.4 mg/ dL in combined vascular complication which group showed increase of TAT but also had no significant increase after correction of age. 4. In diabetic microvascular complication patients, group of high HbA_1c (>8%) (p=0.049) had significant high PIC concentration. In diabetic macrovascular complication patients, group of high HbA_1c (>8%) (p=0.042) had significant high total cholesterol concentration. 5. In all diabetic patients, PIC was positively correlated with fibrinogen and HbA_1c and negatively correlated BMI (r=0.47, 0.31, -0.25). Only in daibetic patients without angiopathy, TAT was positively correlated with HbA_1c (r=0.67). Conclusion : In this study, plasma TAT and PIC concentration significantly increased in diabetic patients compared with controls, and PIC was increased in group with microvascular complication, TAT were increased in group with combined micro macrovascular complication. However, there was no significance relationship existed when correctinf for age. PIC was correlated with HbA_1c. TAT was correlated with HbA_1c only in the group without angiopathy. Abnormality of coagulation and fibrinolysis were combined in diabetes, plasma TAT and PIC can be used as an index of vascular complication. Also we found the correlation with the degree of the blood glucose control. Therefore we need follow up study for the possibility of prevention of vascular complication after controlling the blood glucose to age-matched patients (J Kor Diaabetes Asso 25:354~363, 2001).

Oculomotor nerve palsy of acute onset with sparing of the pupil in older age is frequently associated with diabetes mellitus. A 73-year-old diabetic woman was admitted because of vertical diplopia and gait disturbance. Neurological examination showed that the left eye had decreased light reflex, dilated pupil, and limited adduction, supraduction and infraduction. Brain MRI and MRA were unremarkable. Two months after onset, movement, pupil size and light reflex of the patient's eyes were normal on examination. It is emphasized that the diabetic ophthalmoplegia can involve the pupil. We report a rare case of diabetic oculomotor nerve palsy with pupil involvement.

휴전선 인접 마을의 새마을운동 사례를 통해 본 1970년대 한국 농촌사회 정치·경제적 변화 : 강원도 철원군 사곡2리와 군탄1리를 중심으로

김수경,최은봉 이화여자대학교 2005 사회과학연구논총 Vol.14 No.-

이 논문은 1970년대 권위주의 유신체제 하에서 농촌근대화를 목적으로 추진되었던 새마을운동이 한국 농촌사회에 어떠한 정치적·경제적 변화를 초래하였는지 살펴보는 것을 목적으로 한다. 실증적인연구제시를 위해 강원도 철원군 근남면 사곡2리와 갈말면 군탄1리 두 마을의 새마을운동을 사례로 분석하였다. 이 사례연구는 한수이남에 집중되어 있던 기존 새마을운동 연구의 공간적 범위를 휴전선인접지역까지 확장시켰다. 1970년대 당시 두 마을 새마을지도자들과의 인터뷰 자료와 현재 마을회관에 남아 있는 새마을운동사업 기록을 토대로 마을간 사업추진 방식과 두 마을 주민들의 참여태도, 사업성과 둥을 분석하였다. 철원군 근남면 사곡2리와 갈말면 군탄1리의 새마을운동 전개양상은 마을의 입지조건 및 마을 구성원의 차이에 따라 상이한 결과로 나타났다. 사례연구의 케이스가 협소하긴 하지만, 이 연구를 통해서 새마을운동이 직 ·간접적으로 농촌사회에 가져온 변화를 찾을 수 있었다. 새마을운동은 마을 단위로 진행되었기 때문에 동일 지역에서도 마을구성의 상이한 조건적 차이로 인해 새마을운동의 결과도 다르게 나타났다. The objective of this thesis is to see political and economic changes in Korean rural society in 1970s when Saemaul Undong(Movement) was launched by authoritarian government for the modernization in an agricultural district. This paper focuses on Saemaul Undong in two villages of Cheorwon, Kangwon Province or Sagok2-ri and Cuntanl-ri in order to provide actual evidence. Based on the interviews of two towns' then Saemaul Leaders and the information on Saemaul Undong of those areas during the 1970s, this research analyzes people's attitudes, the way of the Movement and the achievement of the Movement. In addition, this paper emphasizes on some changes in political and economic areas of the two villages for about 8 years, comparing to before and after the movement being implemented. They have similarities as well as differences in the stages of Saemaul Undong. firstly, it led the dwellers to actvely participate in the process. Secondly, the residents could express their opinion to the government through the town meefngs. Thirdly, newly-elected leaders, called Saemaul Undong leaders were main actors who are at the center of the course. Although they took the helm just within the Saemaul Undong project, their capacities resulted in various consequences of the Movement under the autonomy of the town unit. Apart from other changes, it altered the appearances of the rural communities. It came to build new roads, convert old houses to modernized ones. It is difficult to say that Saemaul Undong has drawn the actual increase in the economic incomes. However, development in the repairing facilities in it played a key role in going up in the crop productivity, Therefore, it is fair to say that Saemaul Undong had a positive effect on the agricultural economy to some extent.

In order to get healthy seedling of rice suitable for rice transplanter, the growing characteristics of the seedling grown under different growing days and sowing densities were invesigated and the results obtained were summarized as follows; In the 20 days old seedling, the difference of growing state of seedling and its characteristics between the two types of nursery bed was not found, but for the 30 days old seedling, both of the crop growth rate and the relative growth rate on the band-type nursery bed appeared higher than those on the mat-type nursery bed. And also, the dry weight, the content of cardohydrate and the ratio of dry weight to plant height of the seedling grown on the band-type nursery bed were much higher than those on the mat-type nursery bed, however the amount of difference of seedling characteristics between two types of nursery bed was decreased for 40 days old seedling and leaf number was not increased. The amount of the seedling growth was increased with less density of sowing and for the difference between the higher and the less density, the difference getting bigger with the longer nursery days. The maximum density of sowing was approximately 200cc per nursery case on the band-type nursery bed and 250cc per nursery case on the mat-type nursery bed. It was seemed that the growing uniformity of the seedling grown on the mat-type nursery bed was better than that on the band-type nursery bed, As the coefficient of variation of the plant height and leaf numbers of the seedling grown on the band-type nursery bed was higher than that on the mat-type nursery bed.

Background and purpose : Poststroke depression is common and linked to poor prognosis and higher mortality after stroke. Previous studies suggest that high level of serum homocysteine and low levels of vitamin B12 and folate may cause depression. However previous studies has showed large variation concerning the influencing factors of poststroke depression. The purpose of this study was to evaluated the factor that influencing the poststroke depression including serum levels of homocysteine, vitamin B12 and folate. Methods : Beck depression inventory (BDI) was obtained in 62 patients with cerebral infarction, and the patients were divided into non-depression group (BDI ≤ 13) and depression group (BDI ? 14) according to their BDI scores. Then, we compared serum homocysteine, vitamin B12, folate, age, sex, Barthel index, Scandinavian stroke scale, acute aphasia screening protocol, Korean version of mini-mental state examination and ischemic brain lesion between NDG and DG. And also calculate the correlations between serum homocysteine, vitamin B12 and folate with severity of poststroke depression. Results : The NDG were 41 patients (66.1%) and DG were 21 patients (33.9%). Serum homocysteine, vitamine B12 and folate were not different between the groups, and these levels were not correlated with the severity of BDI. The age, sex, BI, SSS, AASP, K-MMSE and location of ischemic stroke were not different between the groups. Conclusion : Frequency of poststroke depression were high in patients with acute ischemic stroke. In contrast with previous studies, poststroke depression was not influenced by the serum levels of homocysteine, vitamin B12 and folate. And poststroke depression was not influenced by age, sex, physical handicap after stroke, aphasia, cognitive function and location of ischemic stroke.
