삼나무, 편백나무의 經濟林 造林에 있어서 활착율이 極히 低調한 事例가 往往 있었다. 이에 對한 영향 因子를 究明코저 一次로 1-1의 實生山出苗와 삼나무의 揷木苗를 供試材料로 하여 室外, 室內 OED green을 葉莖에 處理한 것과 無處理한 것을 午前, 午後 종일 室內에서는 4日間 乾燥處理한 後 침적처리 시험을 하였으며 아울러 함수율을 測定分析하였다. 處理된 苗木은 同一 條件의 苗床에 植栽하여 만족할만한 관리를 하였던 바 다음과 같은 結果를 얻었다. 1. 삼나무, 편백나무의 山出苗의 OED green처리는 室內와 室外間에 高度의 有意性이 있었으며 무처리의 경우 오전, 오후, 종일 間에도 高度의 유의성이 있었다. 침적처리는 유의성이 없었다. 2. 삼나무 揷木苗는 건조처리간에 고도의 유의성이 있었다. 건조시간과 침적시간과의 상호작용에 유의성이 있었다. (6時間 건조할 경우 8時間 침적하였을 때 效果가 있었다) 3. 室內에서 4日間 건조처리를 계속했을 때 2日 경과 後부터 활착율이 현저히 떨어졌다. OED green 및 침적처리는 유의성이 없었으나 무처리에 비해 좋았다. 4. 함수율은 9時부터 15時사이에 급속히 떨어졌으며 室內에 比하여 室外處理가 극히 낮았다. 5. OED green과 無處理間의 含水率은 差가 적었다.

A woman developed a slowly progressive speech disturbance at age 51. Three years latter she showed difficulty in calculation, reading and writing. At age 57, she complained of right shoulder pain. At age 58, neurological examination revealed rigidity, bradykinesia and ideomotor apraxia in the right upper extremity. This case demonstrats a clinical overlap between progressive nonfluent aphasia and corticobasal degeneration.

Background and Purpose Cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited microangiopathy caused by mutations in the Notch3 gene. Although previous studies have shown an association between lacunar infarction and cognitive impairment, the relationship between MRI parameters and cognition remains unclear. In this study we investigated the influence of MRI parameters on cognitive impairment in CADASIL. Methods We applied a prospective protocol to 40 patients. MRI analysis included the normalized volume of white-matter hyperintensities (nWMHs), number of lacunes, and number of cerebral microbleeds. Cognition was assessed with the aid of psychometric tests [Mini-Mental State Examination (MMSE), Alzheimer’s Disease Assessment Scale-cognition (ADAS-cog), Trail-Making Test, and Stroop interference (Stroop IF)]. Results A multivariate regression analysis revealed that the total number of lacunes influenced the performance in the MMSE, ADAS-cog, and Stroop IF, while nWMHs had a strong univariate association with ADAS-cog and Stroop IF scores. However, this association disappeared in the multivariate analysis. Conclusions These findings demonstrate that the number of lacunes is the main predictive factor of cognitive impairment in CADASIL.

This study focuses on two primary purposes. First, we will present the direction necessary for strengthening ‘local autonomy and decentralization’ by discovering the tasks to diagnose and improve actual conditions of ‘local autonomy and decentralization’ in Busan. Second, “the master plan for local autonomy and decentralization” of President Moon's Government will be re-interpreted, and cooperative response measures of Busan Metropolitan City for effective promotion of theirs‘ among the 6 major strategies and 33 projects. To this end, the promotion trends of strengthening of ‘local autonomy and decentralization’ in the government and Busan Metropolitan Government were analyzed, and a survey was conducted on 31 experts related to ‘local autonomy and decentralization’. The main contents of survey are as follows: evaluation of each field of Busan Metropolitan City’s performance for strengthening ‘local autonomy and decentralization’, prioritization of 6 major strategies and 33 projects of “the master plan for local autonomy and decentralization, findings of counterstrategies for strengthening ‘local autonomy and decentralization’, and so on. Finally, analysis results are interpreted and the implications are presented. Next, vision system chart(proposal) has been suggested for organizing basics to strengthen ‘local autonomy and decentralization’ centered on new vision as part of the correspondence strategies for strengthening ‘local autonomy and decentralization’ of Busan Metropolitan City. In addition, 4 different strategies for responding to each field are presented. They include a strong demand for fiscal decentralization and strengthening of self-governing capacity, promotion of abiding by the principle of decentralizing first and then supplementing gradually, seeking to strengthen residents’ participation to administration and policy and administration by governance, requesting to adhere to the principle of neighborhood autonomy and subsidiarity. In particular, 8 strategies and 22 action plans were suggested in conjunction with “the master plan for local autonomy and decentralization” of government. Finally, policy proposals has been suggested in four aspects. First, Busan Metropolitan City must enhance image of a leading city of ‘local autonomy and decentralization’ through holding proclamation ceremony of vision about ‘local autonomy and decentralization’ with participation of residents. Second, Busan Metropolitan City needs to strengthen feasibility of 33 projects of “the master plan for local autonomy and decentralization by the phased and customized responses. Third, affairs of local government which can be devolved must be continuously examined and their devolution must be practiced through cooperation between the city government and the Gu&Gun governments. Fourth, another movement for constitutional amendment proceeded by a decentralized pattern must be accelerated together with residents.
