The purposes of this study was subjected a scheme to improve technical highschcol “2+lsystem” curriculum. The method of the study for carrying out the study is as follows. First, the realities of management were analyzed through the preceding study related with technical highschool “2+lsystem” and the plan of school education of technical highschool “2+1 system” management school. Second, the conference of the teacher in charge of technical highschool management school and the person in charge of the department related with Education City and Province Hall was held. Third, the question search was practiced to all school subjects in the whole country through the electronic document with the help of ministry of education & human resources development (N=930). The effect of the study is as follows. First, the thing which is formed in the schools and industries of technical highschool “2+lsystem” curriculum formation must be made to manage according to the seventh curriculum. Second, the field practice of the present type must be made to carry out in technical highschool as well during the third grade (mid term, final term). Third, the curriculum formation by system improvement and the completed unit (216 unit) are drawn up according to the seventh curriculum.

Onion is one of the most important crops in the world. It is consumed as raw or as a component of meals in many different cultures around the world and without any special time. A long stages from harvesting to consumer might be losing the quality of onion. The step that takes a big loss is during the storage and distribution stage. Therefore, this study is attempted to develop a prediction model of onion quality change during storage and distribution to see how the onion is decaying through artificial neural network using real time scale database. By the result of this study, it is expected that it will be prevent a discrepancy in supply chain and demand existing in the storage and distribution of onion and improve overall efficiency.

<P>We explore structural changes of the carbon in MnO<SUB>2</SUB>/reduced graphene oxide (RGO) hybrid materials prepared by the direct redox reaction between carbon and permanganate ions (MnO<SUB>4</SUB><SUP>–</SUP>) to reach better understanding for the effects of carbon corrosion on carbon loss and its bonding nature during the hybrid material synthesis. In particular, we carried out near-edge X-ray absorption fine structure spectroscopy at the C K-edge (284.2 eV) to show the changes in the electronic structure of RGO. Significantly, the redox reaction between carbon and MnO<SUB>4</SUB><SUP>–</SUP> causes both quantitative carbon loss and electronic structural changes upon MnO<SUB>2</SUB> deposition. Such disruptions of carbon bonding have a detrimental effect on the initial electrical properties of the RGO and thus lead to a significant decrease in electrical conductivity. Electrochemical measurements of the MnO<SUB>2</SUB>/reduced graphene oxide hybrid materials using a cavity microelectrode revealed unfavorable electrochemical properties that were mainly due to the poor electrical conductivity of the hybrid materials. The results of this study should serve as a useful guide to rationally approaching the syntheses of metal/RGO and metal oxide/RGO hybrid materials.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpccck/2014/jpccck.2014.118.issue-5/jp411176b/production/images/medium/jp-2013-11176b_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jp411176b'>ACS Electronic Supporting Info</A></P>

Traditional Chinese herbal drugs, namely, Atractylodes Rhizome and Atractylodes Rhizome White were identified by means of chemical analysis such as TLC and GC/MS. In Korea, the old-grown and the newly-grown rhizomes of Atractylodes japonica Koidzumi (Compositae) are used as the Atractylodes Rhizome and the Atractylodes Rhizome White, respectively. Both rhizomes contain the atractylon as a major spot on TLC. The content of atractylon in a newly-grown rhizome of A. japonica (Atractylodes Rhizome White called in Korea) appears to contain much larger quantity in comparison with that of an old-grwon one (Atractylodes Rhizome). The TLC spot pattern analysis showed that rhizomes of A. japonica and A. macrocephala contain the atractylon as a major indicator spot, but no atractylodin (extreamly small amount). However, rhizomes of A. lances De Candolle and A. koreana Kitamura contain the atractylodin as a major indicator spot.
