This study was aimed to reduce the period of bed log through the protection of harmful fungi and to investigate the effects of physiologically activating substance on the yield increase of Lentinus edodes. Extracts of Allium fistulosm, Hordeum vulagare var. hexastichon, Lentinus edodes. Daucus carota var. sativa, and Citrus junos were used as a physiologically activating substances. The degree of mycelial growth tested by color change after Benzene - azo - ${\alpha}$ - naphthylamine. One percent extract of Album fistulosm was most highly effective as a physiologically activating substance on mycelial biomass growth of Lentinus edodes. Best effects of application of physiologically activating substance was observed in Quercus variabilis bed logs. These results suggested that supplement with physiologically activating substance to the bed log would be beneficial for the production of Lentinus edodes.

Thermogravimetric analysis of copolymer of acrylonitrile(95%) and methyl acrylate(5%) have been carried out to investigate the activation under $H_2O$(30%) -$N_2$atmosphere at various heating rates. The kinetic equation [$f=1-\exp(-a{\Delta}T)^b$] which was derived on the basis of the nonisothermal activation process of carbon fiber in the $H_2O$(30%)-$N_2$system showed good agreement with experimetal results. The pore volume upon conversion was in good agreement with the model of theoretical pore volume. The pore structures of the activated carbon fiber were influenced by the heating rate, activation temperature and internal-external conversions.

본 논문은 대뇌 활성화 상태 변화와 혈액형간의 상관성 분석을 목적으로 한다. 혈액은 인체의 혈관을 통하여 몸 전체로 순환하는 액체 성 물질이다. 이 혈액을 구성하는 물질의 이질적 차이를 나타내는 차별적 유형을 혈액형이라 하며, 혈액형은 멘델의 법칙에 따라 부모에서 자식으로 유전된다. [1] 최근 들어 혈액형이 가지는 유전적 특징을 통한 질병 진단 및 치료, 예방을 위한 연구가 진행되고 있으나, 대부분의 연구는 육체적인 질병과 관련되어 있는 실정이다. 그러나, 혈액형의 경우 유전적 특성을 가지고 있으며, 신경 전달 망에 영향을 끼칠 것으로 추정 되는바 육체적 질병뿐만 아닌 정신적인 질환에도 혈액형에 따른 치료 및 예방방법을 차별화 하여, 보다 효율적인 치료 및 예방을 수행 할 수 있을 것으로 판단된다. 본 논문에서는 이를 위하여, 외부자극에 따른 대뇌 활성화 상태 변화를 분석하며, 특히 혈액형에 따른 상태변화의 상관성을 분석하고자 한다. 본 논문에서 활용하는 외부 자극은 청각 자극을 활용하며, 먼저 혈액형에 따른 피험자 군의 분류를 수행하여 동일 군 내 공통반응 및 상이한 군 간의 특이반응을 분석하여, 혈액형이 대뇌 활성화 상태 변화 및 정신질환에 따른 증상발현 등과 유관함을 검증하고자 한다.

Purpose: We investigated the statistical methods to compose the functional brain map of human working memory and the principal factors that have an effect on the methods for localization. Materials and Methods: Repeated PET scans with successive four tasks, which consist of one control and three different activation tasks, were performed on six right-handed normal volunteers for 2 minutes after bolus injections of 925 MBq $H_2^{15}O$ at the intervals of 30 minutes. Image data were analyzed using SPM96 (Statistical Parametric Mapping) implemented with Matlab (Mathworks Inc., U.S.A.). Images from the same subject were spatially registered and were normalized using linear and nonlinear transformation methods. Significant difference between control and each activation state was estimated at every voxel based on the general linear model. Differences of global counts were removed using analysis of covariance (ANCOVA) with global activity as covariate. Using the mean and variance for each condition which was adjusted using ANCOVA, t-statistics was performed on every voxel To interpret the results more easily, t-values were transformed to the standard Gaussian distribution (Z-score). Results: All the subjects carried out the activation and control tests successfully. Average rate of correct answers was 95%. The numbers of activated blobs were 4 for verbal memory I, 9 for verbal memory II, 9 for visual memory, and 6 for conjunctive activation of these three tasks. The verbal working memory activates predominantly left-sided structures, and the visual memory activates the right hemisphere. Conclusion: We conclude that rCBF PET imaging and statistical parametric mapping method were useful in the localization of the brain regions for verbal and visual working memory.

In distributed real-time system, a task activated by the completion of its preceding task can be modeled as a periodic task with activation jitter. An activation jitter of a task is defined asthe difference between the worst case and the best case response time of its preceding task. Becausethe existing approaches assume that the best case response time is much smaller than the actual one,the activation jitter and the worst case response time of lower priority tasks are overestimated. Thispaper proposes a new analysis technique to calculate the best case response time more precisely andto reduce the activation jitter bounds. The proposed technique obtains the best case response time byconsidering the relative phase between tasks. The precise analysis of the activation jitters can reducethe worst case response time of other tasks and increase the schedulability. The simulation resultsshow that the proposed analysis technique improves the accuracy of the best case and the worst caseresponse time up to 40% and 6%, respectively.

The purpose of this study was to explore ways to revitalize the community-based child care community by identifying the factors that are hindering and activating the operation and use of this community by elementary school students. To this end, an in-depth interview survey was conducted of operators of child care communities in Jeollabuk-do and users of caring communities. Detailed themes, sub-ranges and upper ranges were determined through a qualitative research method. As a result of the study, it was determined that the basic environmental weakness of the caring community and its lack of power are the things hindering the operation and use of rhe communities the most. On the other hand, the main activation factors for community-based child care community activities were the stabilization of the environment and the strengthening of the internal capacity of the care community. This study is meaningful as basic data for the safe establishment and activation of a community-based child care community, which is emerging as an alternative to the child care gap due to the prolonged effects of COVID-19.
