This research investigates language lstrategies focusing on the four domains of communicative competence. A survey was conducted among 421 participants in three different countries over three years using Language Strategy Use Inventory. The quantitative data from the survey was analyzed using univariate ANOVAs and Pearson correlation in SPSS 24. The findings are as follows: 1) The greatest frequency of strategies appeared in the category of discourse competence followed by strategic competence, grammatical competence, and then sociolinguistic competence. 2) The analysis of strategies according to the variables of learners revealed that grammatical competence is influenced by Korean study place; sociolinguistic competence is influenced by gender, overseas study experience, Korean study place, graduation/schooling country, KFL/KSL, and heritage status; strategic competence is influenced by gender; and discourse competence is not influenced by any factors.

Dual Rh(II)/Pd(0) Relay Catalysis for One-Pot Synthesis of α-Quaternary Allylated Indolin-2-ones and Benzofuran-2-ones

이유림,이규리,Zi Xuan,이상기 대한화학회 2021 Bulletin of the Korean Chemical Society Vol.42 No.3

Cooperative Rh(II) and Pd(0) dual relay catalysis has been developed, which allowed one-pot synthesis of α-quaternary allylated indolin-2-ones and benzofuran-2-ones. The catalytic reaction proceeded through the sequential Rh(II)-catalyzed intramolecular aromatic C(sp2)-H bond functionalization of α-diazo carbonyl compounds, followed by Pd(0)-catalyzed allylic alkylation with allylic carbonates to afford the products in high yields (up to 97%).

Brickwell, located in Tongui-dong, Jongno-gu, used as a complex cultural space called ‘Ground Seesaw’, is a place visited by many people by sharing exhibition information through SNS. Baeksongteo, located adjacent to Brickwell, is also visited by many people through a program called ‘Sejong Seochon Village Tour’. This study is a study on the difference in perception of design concepts between designers and users. Based on an understanding of the space called Brickwell through precedent studies on the form and characteristics of void spaces, historic green spaces, complex cultural spaces, and connection with adjacent green spaces, three methods: survey, interview, and behavioral observation by conducting a detailed analysis of the connection between design intent and users. As a result of the analysis, it was found that the connection between users of Brickwell and Baeksongteo was not large, and the most frequent exhibition visitor for the purpose of visiting had a high frequency of using cafes after visiting Brickwell. Through an interview, it was found that there are not a few users who know the historical meaning of Baeksongteo and are looking for it. Although this study has limitations in the study, such as the limitation of the research target site, the limitation of spatial guidelines, and the indirect investigation of design concepts, the significance of this study is to examine the relationship between the designer and the user and whether the design intention is communicated. ‘그라운드시소’라는 복합문화공간으로 이용되고 있는서울시 종로구 통의동에 위치한 브릭웰은 SNS를 통해전시정보를 공유하여 많은 이들이 방문하고 있는 곳이다. 브릭웰과 인접하여 위치한 백송터도 ‘세종 서촌마을투어’라는 프로그램으로 많은 이들이 찾는 곳이다. 본 연구는 설계자와 이용자 간의 설계개념에 관한인식의 차이에 관한 연구로서 공간 이용행태를 통해설계의도와 이용자의 연계성을 파악하고자 하였다. 보이드 공간의 형태와 특성, 역사성이 담긴 녹지공간, 복합문화공간, 인접 녹지와 연계성에 관한 선례연구를 통해 브릭웰이라는 공간에 대한 이해를 바탕으로설문조사, 인터뷰, 행태관찰 등 3가지 방법을 실시함으로써 설계의도와 이용자의 연계성을 구체적으로 분석하였다. 분석 결과, 브릭웰의 이용자와 백송터 간의 연계성은 크지 않은 것으로 나타났으며 방문 목적에서 가장빈도수가 높았던 전시관람 이용자는 브릭웰 방문 후카페 이용으로 이어지는 빈도가 높았다. 인터뷰를 통해 백송터의 역사적 의미를 알고 방문하는 이용자들이적지 않음을 알 수 있었으나, 개별 공간에 대한 설계개념 전달 노력이 더욱 필요한 것으로 판단되었다. 본 연구는 조사대상지의 제한성, 공간 지침상의 한계, 설계개념의 간접적 조사 등에 관한 연구의 한계성을 가지고 있으나 설계자와 이용자 간의 관계를 살펴보고, 설계의도의 전달 여부에 대해 살펴본 것은 이연구의 의의라고 할 수 있겠다.

Purpose : This study aims to identify job stress, emotional intelligence, and exhaustion of the nurses in comprehensive nursing service units and then verify the moderating and mediating effects of emotional intelligence on the relationship between job stress and exhaustion. Methods : Participants are 118 nurses working in two general hospitals. The collected data are analyzed using the SPSS WIN 27.0 and AMOS 18.0 programs by assessing frequency and percentage, mean and standard deviation, independent t-test and one-way ANOVA, Scheffé test, Pearson correlation coefficient, and hierarchical multiple regression analysis and bootstrapping. Results : Exhaustion has a statistically significant positive correlation with job stress (r=.40, p <.001) and a statistically significant negative correlation with emotional intelligence (r=-.26, p =.004). A partial mediating effect of emotional intelligence is found between job stress and exhaustion, however, there is no moderating effect. Conclusion : It is expected that to reduce the exhaustion of nurses in comprehensive nursing service units, it is necessary to assess job stress and emotional intelligence, and strengthen emotional intelligence along with job stress intervention.

의료용 초음파 영상 시스템에서 채널신호의 스펙트럼에서 거리 가중치를 이용한 부엽의 억제

In medical ultrasound imaging systems, Side lobes may appear if signals outside the imaging point are not completely removed during receive focusing. If the time signal of the side lobe overlaps with the time signal (main lobe) from the image point, it is difficult to completely remove it using filter processing in the time domain. However, In the receive focusing process, when time-channel signals are Fourier-transformed, the main lobe and side lobe signals are spatially separated in the spectral domain. Therefore, the side lobes can be suppressed by multiplying the image with magnitude weights, which are determined by the magnitudes of the main and side lobes calculated in the spectral domain. In addition, when the main lobe and the side lobe spectrum are adjacent, the distance weight was applied based on the distance between them. In a 5 MHz ultrasound imaging system using a 64-channel linear transducer, point reflector and speckle images with cysts of various brightness were synthesized and weights were applied to the ultrasound image. Using computer simulations, we confirmed that the side lobes were greatly reduced without affecting the spatial resolution in the point reflector image, and the contrast was significantly improved in the cyst image with computer simulations. 의료용 초음파 영상 시스템에서, 영상점의 밖에서 오는 신호가 초음파 수신 집속 과정에서 완전히 제거되지않으면 부엽을 발생시킨다. 부엽의 시간 신호가 영상점에서 오는 시간 신호(주엽)와 같이 중첩되어 나타나면 시간 영역에서 필터 처리를 이용하여 완전히 제거하기 어렵다. 그러나 수신 집속 과정에서 시간 -채널 신호를 푸리에 변환하면, 주엽과 부엽의 신호는 주파수 스펙트럼 영역에서 공간적으로 분리가 된다. 따라서 스펙트럼 영역에서 계산한 주엽과부엽의 신호크기를 이용하여 크기 가중치를 계산하여 영상에 곱함으로써 부엽을 억제하였다. 그리고 주엽과 부엽의스펙트럼이 인접할 때, 주엽과 부엽 스펙트럼 사이의 거리에 따라 거리 가중치를 적용하였다. 64 채널 선형 트랜스듀서를 사용하는 5 MHz의 초음파 영상 시스템에서 점확산 영상과 다른 밝기의 낭종을 가지는 스페클 영상을 합성하고 가중치를 적용하여 초음파 영상을 계산하였다. 점반사체 영상에서 해상도의 변화 없이 부엽이 크게 줄어들었으며 낭종영상에서 대조도가 크게 개선됨을 컴퓨터 시뮬레이션으로 확인하였다.

"Objectives: This study aimed to identify the socioeconomic factors related to tooth brushing behavior among adults in Korea. Methods: This cross-sectional study used data from the Korea Community Health Survey (KCHS) in 2019. Respondents aged 19 years and older (n=299,099) comprised the study sample. The dependent variable was tooth brushing behavior, whereas the independent variables were demographic and socioeconomic factors. The data were processed using chi-squared test, independent t-test, ANOVA, and adjusted multiple logistic regression analysis were performed. Statistical analysis was performed using the STATA 17.0 program, with significance set at the 5% level. Results: About half (55%) of the respondents brushed their teeth at least twice a day. The findings also revealed significant differences according to socioeconomic status (P<.01). Those who brushed their teeth less than twice a day had the following characteristics: men, aged 45 years or older, low income, working outside, less educated, without a spouse, and living in rural areas. Adjusted multiple logistic regression analysis showed that the area of residence contributed to tooth brushing behavior. Conclusions: The area of residence, as well as socioeconomic status, should be considered in oral health education and intervention strategies."
