This paper argues that there are circulative linkages between knowledge creation, sharing and utilization in innovative clusters. Based upon discussion about characteristics of circulative linkages between three types of knowledge activities, this paper presents three hypotheses: the more regions generate knowledge, the more active they share knowledge (hypothesis I); the more regions share knowledge, the more vigorous they utilize knowledge (hypothesis II) and the more regions generate knowledge, the more vigorous they utilize knowledge (hypothesis III). Empirical analysis into the Korean case turned out that hypotheses I and III were strongly supported, but hypothesis II weakly supported, probably due to inaccurate proxies for knowledge activities. This study may help guide provincial governments to choose policy goals to promote knowledge activities. It also leads to the conclusion that maintaining balance among three types of knowledge activities (creation, sharing and utilization) is a way of their policy making for the promotion of innovative clusters.

On these days concrete knowledge more than simple information is required in order to do something. In this paper we researched the development methods and design of the Knowledge Management System(KMS) to effectively utilize the human resources and various kinds of intellectual resources of the universities, which is the mecca of the knowledge and technology. We gave our focus to the methodologies that makes it possible to implement the KMS with the least costs based on the available databases and infrastructures.

– In the paper, to handle the problem of traditional bag-of-features model ignoring the spatial relationship of local features in human action recognition, we proposed a Multiscale Spatial Position Coding under Locality Constraint method. Specifically, to describe this spatial relationship, we proposed a mixed feature combining motion feature and multi-spatial-scale configuration. To utilize temporal information between features, sub spatial-temporal-volumes are built. Next, the pooled features of sub-STVs are obtained via max-pooling method. In classification stage, the Locality-Constrained Group Sparse Representation is adopted to utilize the intrinsic group information of the sub-STV features. The experimental results on the KTH, Weizmann, and UCF sports datasets show that our action recognition system outperforms the classical local ST feature-based recognition systems published recently.

Mordern Ocean-going ships utilize stabilization techniques in order to minimize the effects of oscillations due to the unwanted disturbances. In this paper, as an elementary design of automatic control system with linear-state vari;tble feedback and series compensator for ship stabilization, analysis and design is limited to the linear time-invariant single input and output system. In order for the Controlled system to meet the requirements of stability, accuracy and transient response, a model of the automatic control system is proposed. For the analysis and design of this model, the state-space method, that is, the mordern way, or an alternative to the transfer function method of describing a linear system that utilize the state variables and state equations, is applied.

Using a novel pine needle agar, fifteen bacterial species were isolated from pine litter. These bacteria were able to degrade aromatic hydrocarbons derived from lignin and utilize the ortho-cleavage of the $\beta$-ketoadipate pathway to degrade protocatechuate or catechol. A different utilization array of aromatic hydrocarbons by these bacteria was also determined. This study provides the information on bacterial species living in pine litter and suggests that these bacteria have metabolic abilities to utilize aromatic hydrocarbons derived from lignin biodegradation.

A bacterium DGUM 2011 has been selected from various samples of industrial wastewater and soil. Based on the morphological and physiological characteristics, the isolate DGUM 2011 was identified as Rhodococcus sp. and named as Rhodococcus sp. DGUM 2011. The optimal temperature and pH for the cell growth of Rhodococcus sp. DGUM 2011 were 37$\circ$C and 7.6, respectively. When phenol was added to the minimal media as a sole source of carbon and energy, the concentrations of maximum and optimum for cell growth was 0.10% and 0.08%, respectively. When 0.05% phenol was given in the minimal media, Rhodococcus sp. DGUM 2011 completely utilize it within 24 hrs. The isolate could utilize benzoic acid, p-hydroxybenzoate, p-cresol, tyrosine and phloroglucinol. The isolate possessed both catechol 1,2-dioxygenase and 2,3-dioxygenase activity. However, the activity of catechol 1,2-dioxygenase was much higher than that of 2,3-dioxygenase, which suggests that the isolate might degrade phenol via both ortho- and meta-cleavage, mainly via ortho-cleavage.

Recently brainwaves are utilized diversely in the field of medicine, entertainment, education and so on. In the case of medicine, brainwaves are analyzed to estimate patients' diseases. However, the applications for entertainments usually utilize brainwaves as control signal without figuring out the characters of the brainwaves. Given that users' brainwaves are different each other, a normalization method is essential. The traditional brainwave normalization approaches utilize normal distribution. However, those approaches assume that brainwaves are collected enough to conduct normal distribution. When the few amounts of brainwaves are measured, the accuracy of the control signal based on the measured brainwaves becomes low. In this paper, we propose a normalization framework of BCI-based facial interfaces for novel volume controllers, which can normalizes the few amounts of brainwaves and then generates the control signals of BCI-based facial interfaces. In the experiments, two subjects were involved to validate the proposed framework and then the normalization processes were introduced.

The gas-fired absorption refrigeration system to utilize treated sewage is available for environmental protection and energy conservation. Simulation analysis on the double-effect absorption refrigeration cycles with parallel or series flow type has been performed. The working fluid is Lithium Bromide and water solution. The main purpose of this study is evaluating the possibilities of effective utilization of treated sewage as a cooling water for the absorber and condenser. The efficiency of a couple of cycles has been studied and simulation results show that higher coefficient of performance could be obtained for parallel flow type. The other purpose of the present study is to determine the optimum designs and operating conditions based on the operating constraints and the coefficent of performance in the paralledl flow type.

Photosynthetic bacteria which can utilize ferulate as a sole carbon source for their metabolic activities were isolated from soils by liquid enrichment culture technique. The strain P-1 was selected by the highest capability of degrading ferulate in aerobic and anaerobic conditions. The strain P-1 was rod-shaped with its motility, strained gram negatively and could not utilize sulfur compounds. This strain has the bacteriochlorophyll a group I carotenoid and membrane structures like lamellae. As the results of physiological, morphological and cultural charactderistics, the isolate was identified as Rhodopseudomonas plaustris, one of the purple nonsulfer bacteria. The strain P-1 utilized 2mM/day in aerobic condition and 0.86 mM/day in anaerobic condition.

The purpose of this study is to evaluate consumer use of unit price information introduced in Korea 1999. A total of 571 observations were analyzed by frequency, percent, and paired t-test using SPSS. The main findings are (1) consumers use unit price information to make better purchase decisions, (2) consumers with higher than average attentiveness in purchase behavior utilize unit price information to make better buying decisions, and (3) consumers with higher than average knowledge utilize unit price information to make better buying decisions. (4) Also if either attentiveness in purchase behavior or consumer knowledge is lower than average, unit price information helped consumers make better purchase decisions. (5) However, there was no difference among those consumers with below average or above average attentiveness and knowledge.
