Because XML is a W3C standard and has characteristics like platform-independent, it has a critical role in e-commerce. Business rules and Procedures should be standardized for efficient B2B integration. But a lot of companies are its own XML documents instead of standard documents. Therefore many organizations try to make standards for e-commerce based on framework. In this paper, we designed and implemented XML Messaging System based on TCP/IP protocols. This system are designed by module. Because, it is easy to extensibility of system. So we can more easily and efficiently build e-commerce system based on this XML messaging system.

Objective : The purpose of this study is investigate the effects of sensory integration combined with auditory treatment on the sensory processing, visual perception and attention ability of children with developmental delay. Methods : A combined treatment of auditory training and sensory integration therapy was implemented to 3 children aged 4 to 7 and diagnosed with developmental delay during 9 weeks period from December 2016 to January 2017. ABA' design which is one of single subject research designs was used in this study. Baseline A had 4 sessions, intervention B had 15 sessions, and baseline A' had 4 sessions, so 23 sessions were applied in total. During the baseline A and A 'periods, visual perception ability was measured by K-DTVP-2 (Korea Developmental Test Visual Perception-2) and sensory processing ability was evaluated by sensory profile. The maintenance time of attention was measured with the absence of intervention for the baseline period, and for the intervention period, it was measured at 10 minutes break time which was provided after the intervention. The children's attention time during a fine motor task provided were measured using video recorder with the interval recording method, and the interval for the evaluation was 30 seconds. Results : No statistically significant difference were found in the visual perception function and sensory processing scores before and after treatment. Attention of participant A enhanced significantly while that of participant B and C did not improve significantly. Conclusion : It is hard to conclude that sensory integration therapy combined with auditory perception training has positive effects on visual perception function and attention of children with developmental delays. However, there were significant increase in attention and improvements in behavior related to sensory processing for some cases in this study. In further study, longer intervention periods and valid measurement need to be applied in order to get better results. And it is proposed that more studies need to be done to enhance evidence of auditory perception training as a mean to facilitate attention and to prepare learning.

Two rhizobacteria Bacillus aryabhattai H26-2 and B. siamensis H30-3 were evaluated whether they are involved in stress tolerance against drought and high temperature as well as fungal infections in Chinese cabbage plants. Chinese cabbage seedlings cv. Ryeokgwang (spring cultivar) has shown better growth compared to cv. Buram-3-ho (autumn cultivar) under high temperature conditions in a greenhouse, whilst there was no difference in drought stress tolerance of the two cultivars. In vitro growth of B. aryabhattai H26-2 and B. siamensis H30-3 were differentially regulated under PEG 6000-induced drought stress at different growing temperatures (30, 40 and $50^{\circ}C$). Pretreatment with B. aryabhattai H26-2 and B. siamensis H30-3 enhanced the tolerance of Chinese cabbage seedlings to high temperature, but not to drought stress. It turns out that only B. siamensis H30-3 showed in vitro antifungal activities and in planta crop protection against two fungal pathogens Alternaria brassicicola and Colletotrichum higginsianum causing black spots and anthracnose on Chinese cabbage plants cv. Ryeokgwang, respectively. B. siamensis H30-3 brings several genes involved in production of cyclic lipopeptides in its genome and secreted hydrolytic enzymes like chitinase, protease and cellulase. B. siamensis H30-3 was found to produce siderophore, a high affinity iron-chelating compound. Expressions of BrChi1 and BrGST1 genes were up-regulated in Chinese cabbage leaves by B. siamensis H30-3. These findings suggest that integration of B. aryabhattai H26-2 and B. siamensis H30-3 in Chinese cabbage production system may increase productivity through improved plant growth under high temperature and crop protection against fungal pathogens.

Polymerase chain reaction(PCR) was conducted to obtain the gene encoding glucose oxidase(GOD) from Aspergillus niger(ATCC 2110) and the DNA sequence determined was coincided with published GOD sequence from A. niger. Recombinant transforming vector containing GOD and hygromycin B(hyg.B) resistant gene(hph) was constructed and used for further transformation of A. niger ATCC 2110. Selectivity of hyg.B against A. niger differed depending on which media were used i.e., nutrient-rich media such as potato dextrose agar(PDA) and complete medium(CM) showed only 50% growth inhibition at 400 $\mu$m ml$^-1$ of hyg.B while the minimal media inhibited mycelial growth completely at 200 $\mu$m ml$^-1$ of hyg.B. Twenty to sixty putative transformants were isolated from the hyg.B-containing minimal top agar, transferred successively onto alternating selective and nonselective media for a mitotic stability of hyg.B resistance and, then, single-spored. Among the stable transformants, the transformant(GOD1-6) grown by flask culture showed the considerable increase of extracellular GOD activity, which was estimated to the degree of 50% - 100% comparing to that of wild type. Transformation of tGOD1-6 was resulted from integration of the vectors into heterologous as well as homologous regions of the A. niger genome. Southern blot analysis revealed that there were two independent integrations of vector into fungal genome and one into the GOD gene due to homologous recombination. In addition, GOD activity and sodium gluconate production when tGOD1-6 was fed-batch fermented were enhanced 11 fold and 2.25 fold, respectively, compared to that of the wild type.

The concept of temperature distribution in inhomogeneous semi-infinite solids is examined by making use of direct integration method. The analysis is done on the solution of the in-plane steady state heat conduction problem under certain boundary conditions. The method of direct integration has been employed, which is then reduced to Volterra integral equation of second kind, produces the explicit form analytical solution. Using resolvent- kernel algorithm, the governing equation is solved to get present solution. The temperature distribution obtained and calculated numerically and the relation with distribution of heat flux generated by internal heat source is shown graphically.

In this paper, a Ka-band LTCC (low temperature co-fired ceramic) narrow bandpass filter (BPF) is firstly presented. This BPF shows very narrow 3dB fractional bandwidth of 4.5 ％ centered at 28.7㎓. The advantages of multi-layered LTCC technology such as high integration and vertical stacking capabilities were employed to design three-dimensional interdigital end-coupled embedded microstrip narrow BPF. The difficulties in controlling the precise distance between two adjacent resonators in LTCC end-coupled BPF were overcome by locating the resonators on different layers. The measured insertion loss is 3dB at 28.7㎓, pass band is from 27.9 ㎓ to 29.2 ㎓, and the return loss in the pass band is less than 10 dB.
