Recently several techniques for disaster prevention based on IoT(Internet of Things) are being developed. In this paper, a new smart pattern classification method for electric loads is proposed. CT(Current Transformer) data are extracted from electric loads, and then the sampled CT data are converted using FFT and MFCC. FFT and FMCC data are used for the input data of neural networks. Experiments were conducted using FFT and MFCC data for 7 kinds of electric loads. Experiments results indicate the superiority of MFCC in comparison to FFT.

Addition of growth inhibitors such as ancymidol, ABA, chloromequat, and pachlobutrazol into MS medium had no effect to preventing vitrification in cultures of Rehmania glutinosa. Anatomical investigation revealed that vitrified thick leaf tissue in vitro had larger intercellular space with poor development of sponge and pallisade tissue compared to those of in vitro grown glaucous and field grown plants. In vitro grown glaucous leaf had smaller and round type stomata showing distinguishable guard and subsidiary cell than those of reestablished plantlets into soil whereas abnormal stomata and poor development of epicuticular wax on the surface of leaf was observed in verified plantlet.

This paper introduces experimental investigates of an accident pattern for the distributing XLPE cable terminations considering PL law environment. The influence of defects such as thickness and length decrease of XLPE, the impurity on XLPE and the gap between stress-con of housing and semi-conductor on insulating properties of the termination have been studied. The thickness and length decrease of XLPE decrease ac breakdown strengths. Dielectric breakdown traces of XLPE that is damaged by knife displayed other shape. The gap of between housing and semiconductor deteriorates dielectric strength of XLPE seriously.

In order to plasma-sulfnitride by combining ion-nitriding of a steel and sputtering of MoS$_2$, chromium-molybdenum steel was plasma-sulfritrided using hollow cathode discharge with parallel electrodes which are a main of the steel and a subsidiary cathode of $MoS_2$. The treatment was carried out at 823K for 10.8ks under 665Pa in a 30% $N_2$-70% $H_2$ gas atmosphere. Plasma-sulfnitriding layers formed of the steel were characterized with EDX, XRD, micrographic structure observation and hardness measurement. A compound layer of 8-15$\mu\textrm{m}$ and nitrogen diffusion layer of about 400$\mu\textrm{m}$ were formed on the surface of plasma-sulfnitrided steel. The compound layer consisted of FeS containing Mo and iron nitrides. The nitrides of $\varepsilon$-$Fe_2_3N$ and $\gamma$'-$Fe_4N$ formed under the FeS. The thickness of compound layer and surface hardness were different with the gaps between main and subsidiary cathodes even in the same sulfnitriding temperature. The surface hardnesses after plasma-sulfnitriding were distributed from 640 to 830Hv. The surface hardness was higher in the plasma-sulfnitriding than the usual sulfnitriding in molten salt. This may be due to Mo in sulfnitriding layer.

Fick's diffusion equation was transformed into algebraic subsidiary equation with its initial and boundary conditions through Laplace transformation, and the subsidiary equation was transformed back on the basis of Burington's table of inverse transformations so that it became the solution of Fick's equation. The initial and boundary condition was for upward diffusion of salts into flooding water of constant depth from uniform polder soil of infinite depth containing constant concentration of salt. The derived solution was tested through comparison for its conformability with other solutions of simpler initial and boundary conditions. The importance of shallow transplanting of rice seedlings and salt removing by growing rice was mentioned on the basis of very slow desalting rate by diffusion calculated from the derived solutions.

In this study, the alteration of Jook was studied by analyzing and comparing ingredients of Jook appeared in the reference of cookbooks from 1611 to 1958. 121 kinds of Jooks were mentioned 371 times. The Jooks made only with grains, mostly Hin Jook (white Gruel) made of rice, were recorded 31 times in 10 kinds. Rice or processed rice appeared most (194 times) as main ingredients in Jooks other than Hin Jook. As for condiments, honey and sugar were mentioned 37 times, accounting for one third of the condiments recorded as used for Jooks. The basic ingredient of Jooks were rice, but mostly the Jooks were named after the subsidiary materials. Chinese medicinal ingredients were most among the subsidiary materials; 35 kinds of them were mentioned 73 times. As regards the ingredients of the Jook, the other ingredients were added to the grain ingredients between the 17th century and the 19th century whereas only grains were put into Jook during the 20th century.
