This paper proposes a CP-OFDM(Orthogonal Frequency Division Multiplexing using Circular Polarization) system for improving the system performance. The circular polarization has a characteristic that it cannot receive the reflected waves which are reflected by odd times. By reducing the influences of the reflected waves, the circular polarization can reduce the time delay spread and the inter-channel interference. The guard interval needed for the OFDM frame can be minimized and the orthogonality between subchannels can be improved by using circular polarization. Therefore the proposed CP-OFDM system can improve the system performance as well as the spectrum efficiency. Both theoretical analysis and system simulation results are described.

The purpose of this study is to explore the applying possibility of the Earth Systems Education(ESE) in elementary school science education through the improving of students' recognition with the earth systematic nature by systems thinking education - for this was the recognizing as earth systematic nature was the key element of ESE, and the systems thinking skill is accredited very effective tool for the understanding with earth systematic nature. For this, the systems thinking's teaching-learning programs were developed and applied to the 6th students (21s) for 10hours' classes. The results of this study are as follows; In most of the 6th students didn't recognize with earth systematic nature from a lack of understanding of the vapor being in every nature environments. In systems teaching-learning classes, most of students participated positively in learning activities and achieved the aim of a lesson. In the testing results for students' recognition improving to earth systematic nature after the systems thinking education, about 24% students were showed the improving results of the recognition with earth systematic nature. Consequently, It is suggested that just as the achieving of the points of ESE in elementary school science education, the approaching method of the systems thinking education is worth attempting to applying of the ESE.

This research is aimed at examining the effect of the implementation of ABAS and BR on GFP with FDM as mediation. Respondent of research is 100 civil servants at the Directorate General of Population and Civil Registration of the Ministry of Home Affairs for the Republic of Indonesia. Data analysis is done with WarpPLS. Result of research shows that the implementation of ABAS has direct and indirect effects on GFP, and the indirect effect involves the mediation of FDM. Other result indicate that the making of proper financial decisions will help improving GFP. The effectiveness of financial decisions are able to mediate the implementation of ABAS in improve GFP. Meanwhile, BR does not affect GFP, either directly or indirectly through FDM. BR seems oriented more toward improving public service and people's welfare. This research suggests that the next research should examine whether the implementation of BR can improve governmental organizational performance in delivering public service. This research has proven that the implementation of ABAS has helped in improving the quality of FDM, while the other benefit is that this system improves GFP. Moreover, this research also gives confirmation that accounting information in good quality will be very useful in FDM.

The necessity for improving the English listening ability of Korean learners has been emphasized since the ultimate goal of English education converted to CLT(Communicative Language Teaching) in Korea. Verbotonal Approach as an auditory-based strategy has been proved to be effective substantially in maximizing the listening skill of spoken foreign language. The purpose of this study is to find out an efficient way of improving listening ability for Korean middle school students by employing OFH(Optimal Frequency of Hearing) using Tonality Word Sentence Test, before & after using Listen II Verbotonal training unit based on VTS(Verbotonal System). The results of the listening tests showed that the listening ability of the subjects increased by 16.7% on the words and by 5.5% on the sentences after using Listen II, compared with before using Listen II and that the improvement rate of listening ability on the level of words is much higher than that on the level of sentences. From the results, we can come to a conclusion that training the listening skill with words in mid-tonality and low-tonality based on OFH might give a great positive effect in improving listening ability for Korean learners of English.

This study was carried out to clear up the cause of low-acid producing phenomenon occurred In non-fat dry milk during liquid-yoghurt fermentation by Lactobacillus case, and to present its improving methods. All samples of non-fat dry milks which were low in TCA-soluble peptides showed low-acid production, but those high in TCA-soluble peptides showed high-acid production. The addition of trypsin-hydrolysate of Na-caseinate to non-fat dry milk showed some improving effect on acid production but that of papain-hydrolysate did not show any improving effect and that of bacterical neutral protease-hydrolysate showed some inhibitory effect. The improving effects on growth and acid production of lactic acid bacteria were more prominent when the trypsin-hydrolysate of Na-caseinate was added. to such fermenting system in which the levels of TCA-soluble peptides and the proteolytic ability of starter bacteria were abnormally low. The liquid-yoghurt made with non-hydrolysed Na-caseinate and defective non-fat dry milk showed precipitate occurrence but that with trypsin-hydrolysate of Na-caseinate and defective non-fat dry milk did not make any precipitate during storage as with normal non-fat dry milk.
