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.

The purpose of this study is to analyze the effect of storytelling characteristics of TV home shopping and cognitive dissonance reduction behavior on cosmetics brand loyalty and purchase intention, focusing on cosmetics. For the research period, a total of 450 questionnaires were distributed from April 1st to June 20th, 2022, targeting viewers residing in Seoul and Gyeonggi-do who had experience in purchasing cosmetics through TV home shopping, excluding 12 insincere questionnaires. 438 copies were used as final analysis data. For the collected data, SPSS 26.0 statistical package program and Amos 23.0 program were implemented. As a result of the analysis, among the storytelling characteristics factors of TV home shopping, expertise was explained with a positive (+) meaning in the actual reduction behavior and non-responsive behavior of cognitive dissonance reduction behavior, and emotion was explained with psychological reduction behavior and non-responsive behavior in cognitive dissonance reduction behavior. Behavior was positively and significantly explained. On the other hand, interest and ease of understanding, which are storytelling characteristics of TV home shopping, were explained as negatively (-) significantly in the psychological and actual reduction of cognitive dissonance reduction behavior, and then the actual reduction behavior in cognitive dissonance reduction behavior was positively (+) was significantly explained, and brand loyalty was explained positively (+) significantly to behavioral intention. These results can be seen as the fact that storytellers’ emotions generated through advertising and marketing such as TV home shopping can stimulate consumers’ emotions and empathy following positive images and attitudes toward the brand. Accordingly, it was confirmed that it plays an important role in increasing purchase intention by influencing viewer’s situational involvement and empathy. In addition, it can be seen that the storyteller’s reliable knowledge delivery, problem-solving ability, and professional and factual explanation of the product affect women’s satisfaction and purchase intention after purchasing cosmetics. Therefore, through the results of this study, it can be seen that it is an important factor that can provide practically useful information to TV home shopping producers and show hosts in the production of storytelling messages.
TiO<sub>2</sub>광촉매를 이용한 비주류 담배연기의 VOCs제거 효율 연구
이유림,권진홍,김재용 한국공업화학회 2018 한국공업화학회 연구논문 초록집 Vol.2018 No.0
담배연기는 5,000 종류 이상의 화학물질이 포함되어 있고 이 중 발암성 물질은 약 70종으로 알려져 있다. 이는 인체에 유해한 입자상물질과 가스상물질을 다량 함유하고 있는 환경담배 연기이며 실내공기 질을 결정하는 가장 유해한 오염물질로 평가되고 있다. 담배연기 중 실내 공기로 확산되는 연기는 대부분 비주류 연기로 약 87%에 달한다. 본 연구에서는 TiO2 광촉매를 이용하여 비주류 담배연기 내의 포름알데히드(HCHO), 암모니아(NH3), 황화수소(H2S)제거 효율을 확인하고자 한다. 실험 결과, 10분 동안 포름알데히드는 53.61 % 제거되었고 암모니아는 56.00 % 제거되었으며 8.5 분에 황화수소가 모두 제거되는 것을 확인하였다.

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%).

The waste acceptance criteria for heavy metals in mixed waste should be developed by reflecting the leaching behaviors that could highly depend on the repository design and environment surrounding the waste. The current standards widely used to evaluate the leaching characteristics of heavy metals would not be appropriate for the silo-type repository since they are developed for landfills, which are more common than a silo-type repository. This research aimed to explore the leaching behaviors of cementitious waste with Pb, Cd, and Sb metallic and oxide powders in an environment simulating a silo-type radioactive waste repository. The Toxicity Characteristic Leaching Procedure (TCLP) and the ANS 16.1 standard were employed with standard and two modified solutions: concrete-saturated deionized and underground water. The compositions and elemental distribution of leachates and specimens were analyzed using an inductively coupled plasma optical emission spectrometer (ICP-OES) and energydispersive X-ray spectroscopy combined with scanning electron microscopy (SEM-EDS). Lead and antimony demonstrated high leaching levels in the modified leaching solutions, while cadmium exhibited minimal leaching behavior and remained mainly within the cement matrix. The results emphasize the significance of understanding heavy metals' leaching behavior in the repository's geochemical environment, which could accelerate or mitigate the reaction.
