본 연구는 플럭 사운드를 중심으로 만들어지는 음악의 구조적 특징과 음색을 분석하기 위해서 음악에서 플럭 사운드가 중요한 요소로 사용되어지는 저스틴 비버의 ‘What do you mean?’과 에드 시런의 ‘Shape of You’를 선행 연구 곡으로 선정하고, 각 음악에서 주로 사용한 신디사이저 음색과 리듬의 특징을 분석하였다. 그 결과 플럭 사운드는 진폭 엔벨로프의 매개 변수에 따라 다양한 음색으로 나타나는 것을 알 수 있었다. 진폭 엔벨로프는 디케이 타임의 설정 값에 따라 음색의 변화가 큰 특징이 있으며 플럭 사운드는 많은 제작 방법으로 만들어지며 널리 사용되어지고 있다. 현재 발전하고 있는 여러 가지 음악 제작에 있어서 후속 연구가 더해져 더 다양하고 차별화된 제작 기법이 연구되고 발전되길 기대해본다.
In this study, TMD(Tuned Mass Damper) is installed in a retractable-roof spatial structure in order to investigate dynamic response characteristics according to mass ratio and installed position of TMD on large spatial structures. The example analytical model is generated based on the Singapore sports hub stadium. Twenty eight analytical models are used to investigate optimal installation position of TMD for the example retractable-roof spatial structure using 4 to 16 TMDs. The mass of one TMD is set up 1% of total mass at the example analytical model. Displacement response ratio of model with TMD is compared with that of base model without TMD. It has been found from numerical simulation that it is more effective to install TMD at the edge of the spatial structure rather than to concentrate the TMD at the center of the spatial structure.
As a transcription factor, the CCAAT/enhancer binding protein (C/EBP) induces the expression of specific genes by interacting with their promoters. C/EBP can trigger to express other genes, because it can open chromatin structure after binding to DNA, then lead to another transcription factors. In this study, we investigated the features and post-exercise expression patterns of two genes in the C/EBP family, C/EBPβ and C/EBPδ. The basic region leucine zipper motif (bZIP) is a crucial region of C/EBP, and analysis of synonymous and non-synonymous substitution ratios revealed that bZIP regions were well conserved in mammalian species. Quantitative real-time RT-PCR data showed that C/EBPβ and C/EBPδ expression increased significantly in the muscle after exercise, but did not do so in the blood. We therefore propose that exercise-induced increased expression of C/EBPβ and C/EBPδ may stimulate gene expression in physiological pathways in muscle cells.
This study analyzed the impact of FTA tariff elimination on the export prices for Norwegian fresh and chilled salmon, of which Korean import has significantly increased since the Korea-EFTA FTA implementation. Korea's fresh and chilled salmon market is almost monopolized by Norway, and Korea's price level is higher than other countries, so it is highly likely that price discrimination occurs. This study theoretically explained that exporters could adjust their prices by market power when tariffs are eliminated in imperfectly competitive markets. And the empirical analysis provided evidence that the exporters have made price adjustments since the FTA took effect, and similar results were found in the relative price comparison with trade statistics and Nasdaq Salmon Index. Therefore, in order to increase consumer welfare in Korean salmon market, it is required to transform the monopolistic market structure into a competitive one.
『現代漢語詞典』의 해석을 중심으로 ‘快’와 ‘快要’의 의미, 품사, 어법단위를 논의한 결과 ‘快’ 는 어떠한 문맥에 쓰일지라도 ‘움직이는 동작이나 일의 정황이 시간적으로 빠르다’를 의미하는 형용사로 관통되어 주로 술어, 보어, 부사어로 쓰임을 알 수 있었다. 또한 명사로서 ‘성씨’를 의미하기도 한다. 고대에는 ‘捕快’와 ‘馬快’와 같이 명사로서 ‘옛날에 체포하는 부역을 전문적으로 관리하는 것’을 의미하기도 하였다. 고대중국어의 단음절어 ‘快[기쁘다]’의 형태가 현대중국어에서는 비자립형태소로 쓰임도 확인하였다. 『現代漢語詞典』에 부사로 등재된 ‘快要’는 실제 언어 환경에서는 ‘속도가 빠르거나 길을 걷거나 시간이 짧음’을 의미하는 형용사 ‘快 [빠르다]’와 ‘~하기를 원하다’를 의미하는 동사 ‘要’가 연접되어 ‘빨리(곧) ~하려고 하다’의 문맥 의미를 형성한다. ‘快’는 동사나 형용사 술어 이외에도 수량사 술어 앞에도 쓰여 문맥상 ‘빨리(곧)~하려고 하다’라는 문의를 나타냄을 확인하였다. 현대중국어의 실제 언어 환경에서는 수량사 앞에는 ‘快’, 동사술어나 형용사술어 앞에는 ‘快要’가 주로 쓰임도 확인하였다. ‘快 要’는 ‘快[빠르다]’와 ‘要[~하기를 원하다]’ 두 단어의 연접으로 쓰인다고 여긴다.
Squid is a popular seafood in Korea. However, since the 2000s, the squid production has been declining. The unstable supply of the squid products may cause price fluctuations of fresh and chilled squid. These price fluctuations may be relatively more severe than them of other commodities, because the fresh and chilled squid can not be stored for a long period of time. Thus, this study analyzes the structural characteristics of price volatility and price asymmetry of fresh squid based on off-diagonal GARCH model. Data used to analysis of this study are daily wholesale and retail prices of fresh squid from January 1, 2006 to December 31, 2016 provided in the KAMIS. As theoretical approaches of this study, first of all, the stability of the time series is confirmed by the unit root test. Secondly, the causality between distribution channels is checked by the Granger causality test. Thirdly, the VAR model and the off-diagonal GARCH model are adopted to estimate asymmetry effect and price volatility spillover between distribution channels. Finally, the stability of the model is confirmed by multivariate Q-statistic and ARCH-LM test. In conclusion, fresh squid is found to have shock and volatility spillover between wholesale and retail prices as well as its own price. Also, volatility asymmetry effect is shown in own wholesale or retail price of fresh squid. Finally, this study shows that the decrease in the fresh squid retail price of t-1 period than the increase in the t-1 period has a greater impact on the volatility of the fresh squid wholesale price in t period.
