Efficient protocol for plant shoot regeneration of Brassica juncea L. CZERN was established by using organic media components and growth stimulating factors of the vermicompost and coelomic fluids. Formulated organic plant tissue culture media (Vermicompost (30%) extracts supplemented with 20 mL/L coelomic fluid) have shown maximum shoot regeneration when compared with the Murashige and Skoog (MS) medium, which were supplemented with 1 mg/L 6-benzyladenine (BA) and 0.1 mg/L of Naphthaleneacetic acid (NAA). Cotyledon explants produced the highest shoot regeneration frequency from fourday-old germinated seedlings in comparison with non-germinated seedlings. The vermicompost extracts have proved to be the best organic plant growth media to induce shoots from cotyledons compared to the MS media. Statistically significant difference (P = 0.008) for the root length, shoot length (P=0.000350) and the leaves (P=0.375) of the mustard plantlets were analyzed successfully. The survival rate was 98% in the mustard cotyledons on the Vermicompost extract media and 63% on MS media respectively. The coelomic fluid also is much suitable to induce shoots from cotyledons at lower concentrations. It was also shown that the vermicompost extract, which comprised of humic acids along with coelomic fluid, affected shoot regeneration from the cotyledons. An efficient and organic shoot regeneration study was standardized and it can be applicable in the improvement of the economically important crops.

The accelerate effects on the growth rate and the capacity of fermentation of L. delbrukii and B. subtilis was investigated in the Henneberg's medium added by various amounts of cellular components of Chlorella and Scenedesmus and also was investigated in the media added micronutritional elements such as Mn, Fe and Mo, etc. The results in the comparative experiments are as follow; 1. Various amounts of Chlorella cell components in the media accelerated remarkably the lactic acid formation and growth of L. delbrukii. For example, lactic acid formation in the medium of contained 1 percent Chlorella cell components was promoted more than twice effects compare with control. 2. The formation of .alpha.-amylase by B. subtilis in the medium of 2 percent Chlorella cell contents was also promoted more than nine twice effects compare with control. 3. The formation of lactic acid of L. delbruckii in the medium of Scenedesmus cell contents was a little more than in the medium of Chlorella cell contents. 4. The lactic acid fermented level attained with the addition of 0.2-0.25 percent Chlorella cells was the effect of promoting fermentation attained of saturating level at 100$\mu$g. /ml. of Mn and 0. 1 $\mu$g./ml. of Fe.

As IoT applications that provide AI services increase, various hardware and software that support autonomous learning and inference are being developed. However, as the characteristics and constraints of each hardware increase difficulties in developing IoT applications, the development of an integrated platform is required. In this paper, we propose a tool for automatically generating components based on artificial neural networks and spiking neural networks as well as IoT technologies to be compatible with open platforms. The proposed component automatic generation tool supports the creation of components considering the characteristics of various hardware devices through the virtual component layer of IoT and AI and enables automatic application to open platforms.

The waste water treatment facility at rural and mountainous region in catchment areas of dams should be small scale. The wastewater treatment facility of small scale has some specification as follows;1)simple process, 2)low maintenance cost, and 3)high removal efficiency. So, we developed the bioreactor which can be satisfied with the specification of small scale waste water treatment facility. The bioreactor consisted of the anoxic and oxic zone. The two zones were effectively separated by cone type baffle. By the effective separation through CTB, the nitrification and denitrification reaction occurred effectively. Therefore, the removal efficiency of total nitorgen (TN) increased compared to other types of baffle. And, we put into the bio activated media in oxic zone to increase the concentration and activity of microbiology. The media contained the components which were made of many kinds of the minerals to increase the activity of microbiology. Additionally, we observed that the phosphate removal efficiency increased by bio activated media. This is resulted from the coagulation-sedimentation reaction by mineral in components. The average removal efficiencies of TN and TP during Run 2 were 69 and 89% which were 4 and 25% higher than those during Run 1 without the MA, respectively. For BOD, COD, SS and TKN, the average removal efficiencies at Run 2 were slightly higher than those at Run 1. Therefore, we could maintain the high concentration and high activity of microbiology through bioreactor developed in this study. And the removal efficiency of TN and TP increased.

Recently, the efficient disposal of the waste rubber is necessary due to increasing amount of the waste rubbers. In this paper, method of recycling waste rubbers as components of medium for hydroponic rose culture was suggested. We investigated growth of rose, and macro- and micro-elements, pH and EC of the media amended with waste rubber, In the beginning of culture, stress symptoms such as thin brittle stem and incipient wilting were observed, but they disappeared in a few weeks. Concentration of $Zn^{2+}$ in media at flowering increased in proportion to contents of waste tire in the media. pH of media at flowering were in the range of 5.70 to 6.35. Rose growth in all media, except in wasterock wool mixed with EPDM powder at 9:3 ratio, was normal and equivalent to the control in terms of stem length, number of stems harvested and fresh weight.

This paper present a design and implementation of a distributed audio, Video stream service framework based on CORBA for efficient processing and control of audio/video stream. We design software components which support processing, control and transmission of audio/video streams as distributed objects. For optimization of stream transmission performance, we separate the transmission path of control data and media data. Distributed objects are defined by IDL and implemented using JAVA. And device dependent facilities like media capturing, playing and communication channels are implemented using JMF (Java Media Framework) components. We show a connection establishment and control procedure of streams communication. And for evaluation, we implement a test system and experiment a system performance. Our experiments show that test system has somewhat longer connection latency time compared to TCP connection establishment, but has optimized media transmission time compared to CORBA IIOP. Also test system show acceptable service quality of media transmission.

In the present study, a mechanical model is applied to account the effects of the surrounding viscoelastic media on the buckling behavior of single microfilament within the cell. The model immeasurably associates filament's bending rigidity, neighboring system elasticity, and cytosol viscosity with buckling wavelengths, buckling growth rates and buckling amplitudes of the filament. Cytoskeleton components in living cell bear large compressive force and are responsible in maintaining the cell shape. Actually these filaments are surrounded by viscoelastic media consisting of other filaments network and viscous cytosole within the cell. This surrounding, viscoelastic media affects the buckling behavior of these filaments when external force is applied on these filaments. The obtained results, indicate that the coupling of viscoelastic media with the viscous cytosol greatly affect the buckling behavior of microfilament. The buckling forces increased with the increase in the intensity of surrounding viscoelastic media.

The importance of church school education is becoming more emphasized. To maximize the effectiveness and efficiency of church school education, frequent utilization of instructional media is more desirable. Systematic approach to media utilization will be developed by the extabilishment of church media center. The purpose of this study was to review the concept and components of church media center and to survey the current status and hope for the facility of church media center. For the survey the 400 questionnaries were distributed to pastors or missionaries who are responssible for education, or personnels in church media center in Korea. The churches that they belong to have above approximately 500 church members. Among the distributed questionnaires, the 202 were collected. The results of the survey are as follows. The printed media and the AV media were managed separately in most churches. Many church media center was shared the space with other programs. The space was allocated mainly for storage. Most respondants hoped that they have a variety of areas in their churches. Many church media center have no separation between the area for the adults and that for children. However, most respondants hoped the separation of that areas. Followings are suggestions for the plan of church media center facilities. The space only for the church media center should be allocated. Church media center should be located in the first floor of the building as soon as possible. (If there is elevators in the building, it may be located above first floor). If enough space for the church media center is allocated, the areas for the adults and children should be separated by partitions or separate room. The space should consist of various areas like circulation area, reading area, working area for the personnel, production area, and storing area.
