A current differential relay has been used for transmission line protection. The relay may maloperate in the case of a failure of the secondary circuit of a current transformer (CT) because the differential current is produced. This paper presents an algorithm to detect a failure of a CT using the zero-sequence current. If the magnitude of the zero-sequence current is the same as the magnitude of the current of the other healthy phases, a failure of a CT is detected and then the blocking signal is activated. The proposed algorithm prohibit the maloperation of a differential relay in the case of a CT failure and thus increase the security of the relay.

The purpose of this study is to examine the details of grammatical descriptions for education on Korean particles by identifying the distribution and realization patterns of the particles ‘와/과 (wa/kwa), 하고 (hago), and (이) 랑 ((i)rang)’ from the viewpoint of spoken grammar. An analysis was conducted on a corpus of actual spoken words. The cases of using ‘wa/kwa, hago, and (i)rang’ were first extracted, and then their realization patterns were examined in terms of their forms, syntaxes, and semantic functions. These three types of particles were more frequently realized as adverbial case markers than conjunctive particles. In the case of nouns that preceded them, the combinations of ‘wa/kwa’ and general nouns, ‘hago’ and proper nouns, and ‘(i)rang’ and pronouns were relatively frequent. For pronouns, the combination of ‘wa/kwa’ and demonstrative pronouns and the combination of ‘hago’ or ‘(i)rang’ and personal pronouns were commonly observed. In the case of following auxiliary particles, all three types of particles showed high frequencies of their combination with the auxiliary particle ‘은/는 (eun/neun)’, whereas ‘hago’ exhibited its combination with various auxiliary particles. In terms of semantic and functional roles, ‘wa/kwa’ was most frequently realized with comparative meanings, whereas ‘hago’ and ‘(i)rang’ mainly performed the function of indicating the other party in conversations. Regarding the three types of particles discussed in this study, Korean language textbooks mainly deal with their conjunctive function, and thus should be improved in terms of their semantic and functional roles. Moreover, the description of their spoken grammar should also reflect the results of this study on their forms and syntaxes.

RNase E (Rne) is an essential enzyme involved in the processing and degradation of a large portion of RNAs in Escherichia coli. The enzymatic activity of RNase E is controlled by regulators of ribonuclease activity, namely, RraA and RraB. Gram-positive bacterium Streptomyces coelicolor also contains homologs of Rne and RraA, designated as RNase ES (Rns), RraAS1, and RraAS2. In the present study, we investigated the effect of S. coelicolor RraAS1 on the ribonucleolytic activity of RNase E in E. coli. Coexpression of RraAS1 with Rne resulted in the decreased levels of rpsO, ftsZ, and rnhB mRNAs, which are RNase E substrates, and augmented the toxic effect of Rne overexpression on cell growth. These in vivo effects appeared to be induced by the binding of RraAS1 to Rne, as indicated by the results of co-immunoprecipitation analysis. These results suggested that RraAS1 induces ribonucleolytic activity of RNase E in E. coli. RNase E는 대장균(Escherichia coli)에서 수많은 RNA의 가공 및 분해에 관여하는 필수적인 효소이다. RNase E의 효소 활성은 RraA와 RraB에 의해 조절된다. 그람양성균인 Streptomyces coelicolor는 RNase ES, RraAS1, RraAS2라고 명명되는 RNase E와 RraA의 동족체를 가지고 있다. 이 연구에서는 S. coelicolor 유래의 RraAS1이 E. coli에서 RNase E의 효소활성을 저해하는지 연구하였다. 대장균에서 RraAS1의 발현은 RNase E의 과발현에 의해 감소된 세포생장을 더욱 저하시켰으며, RNase E의 기질인 rpsO, ftsZ, rnhB mRNA의 양을 감소시키는 것을 확인 하였다. 이러한 RraAS1의 효과는 공동면역침전실험을 수행한 결과에서 유추할 수 있듯이, Rne 단백질과 RraAS1의 결합으로 유도되는 것으로 보인다. 이러한 결과는 RraAS1이 대장균에서 RNase E의 리보핵산 가수분해 활성을 유도함을 시사한다.

The purpose of this study is to provide basic data for the development and implementation of a housing support policy for young persons by analyzing the differences in perception between the young persons and their parents about parental support for housing expenses. This study uses a self-developed research tool based on previous studies to investigate unmarried young persons aged between 20 and 39 years, who were not students across the country. Data was collected via an online survey by a professional company for a total of 3 days from May 18 to May 20, 2020 targeting 200 young persons who received or are still receiving housing expenses from their parents while living independently from their parents, and 200 women who are parents with children meeting the above young persons criteria. The results are as follows. 1) Both parents and most young participants responded that the combined support for housing expenses amounted to 10 million won or more and less than 50 million won. 2) During the period when housing expenses were borne or expected to be paid in the future, “less than three years in the future” was the most frequent response of parents and “less than one year in the future” was the most frequent response of young persons. 3) The level of burden that young adults currently feel for housing expenses is somewhat higher than that of the parental generations. 4) Both parents and children (young persons) recognized that the level of recognition of the influence of childrens housing expense on parents’ retirement preparation was substantial. 5) young persons were aware of their parents’ burden for housing expenses and showed their willingness to be independent; however, they were reluctant to refuse parental support. 6) Both parents and young persons responded that the responsibility for youth housing support was in the order of “Government and Society > Family or Relatives > Financial Institutions”.
