본 연구의 목적은 성인의 행동억제체계가 사회불안(Social Anxiety)에 미치는 영향에서 경험회피와 정서표현 양가성이 병렬매개역할을 하는지를 검증하는 것이다. 이를 위해 성인 300명을 대상으로 자료를 수집하였고, 분석은 IBM SPSS Statistics 29.0과 PROCESS macro 4.1(Model 4)을 이용하여 실시하였다. 분석 결과, 첫째, 행동억제체계는 사회불안에 직접 적으로 정적 영향을 미치는 것으로 나타났다. 둘째, 행동억제체계는 경험 회피와 정서표현 양가성 각각을 통해 사회불안에 간접적인 영향을 미쳤으 며, 두 매개경로는 모두 통계적으로 유의하였다. 셋째, 두 매개변인의 병 렬효과를 비교한 결과, 경험회피 경로의 매개력이 다소 높게 나타났으나, 정서표현 양가성 또한 독립적으로 사회불안에 유의한 영향을 미쳤다. 이러 한 결과는 사회불안이 단순한 기질적 민감성의 산물이 아니라, 내적 경험 에 대한 인지적 회피와 정서표현에서의 갈등이 병렬적으로 작용하는 복합 적 심리기제에 의해 유지될 수 있음을 시사한다. 본 연구는 사회불안을 기 질–인지–정서의 다층적 관점에서 통합적으로 검증했다는 점에서 이론적 의의가 있으며, 수용전념치료(ACT)나 정서조절 기반 중재의 임상적 활용 가능성을 제시한다.

이 연구는 상담자의 대리외상과 외상 후 성장 간의 관계에 있어 침습 적 반추, 의도적 반추, 지각된 통제감의 관계를 탐색하고자 하였다. 이에 선행연구를 토대로 대리외상과 외상 후 성장의 관계에서 침습적 반추, 의도적 반추, 지각된 통제감의 다중매개 효과를 확인하고자 모형을 설정 하였다. 국내 상담자 280명을 대상으로 대리외상척도, 사건관련반추 척 도, 지각된 통제감 척도, 외상 후 성장 척도 확장판을 사용하였으며 SPSS Statistics 25.0을 이용하여 기술통계와 상관분석, 매개 효과를 검 증하였다. 그 결과, 대리외상으로 인한 침습적 반추는 의도적 반추와 지 각된 통제감을 매개로 외상 후 성장에 간접적으로 긍정적 영향을 미쳤으 며, 특히 삼중 매개 경로가 유의하게 나타났다. 이는 대리외상으로 침습 적 반추가 부정적 정서를 유발하더라도, 이후 의도적 반추와 통제감 회 복을 통해 외상 후 성장으로 이어질 수 있음을 시사한다.

513 magnesium hydroxide sulfate hydrate (MHSH) and Mg(OH)₂ were synthesized by controlling the pH and concentration using a domestic resource, dolomite (CaMg(CO3)2), as the raw material. The MgSO₄ was extracted by treating dolomite with sulfuric acid under various conditions. Hexagonal plate-shaped Mg(OH)₂ and needle-like 513 MHSH were synthesized under the hydrothermal condition. The morphology of the synthesized materials was controlled by adjusting the pH (SO42-/OH- ratio) and hydrothermal reaction time. As the pH of the solution increased, the formation of plate-like structures became dominant, whereas lower pH values (higher SO42- concentration) led to needle-like forms. The results of the 513 MHSH, which was synthesized using reagents and sea bittern, are consistent with the synthesis conditions, and we observed changes in the length and aspect ratio of the needle-shaped structure in response to adjusting the hydrothermal reaction time.

Synthesis of high-purity magnesium hydroxide using dolomite and bittern is important for use in various applications. We synthesized magnesium hydroxide using bittern and dolomite, which are domestic resources. In Bittern, there is a high concentration of Mg2+ ions, but the impurity Ca2+ ion content is also significant, requiring a purification process to remove it. There are two main methods for this purification. Firstly, there is a separation method that utilizes the difference in solubility between Mg2+ ions and Ca2+ ions by using sulfuric acid on dolomite. Adding MgSO4 solution from dolomite to Bittern removes Ca2+ ions as CaSO4. This process simultaneously purifies Ca impurities and increases the Mg/Ca ratio by adding extra Mg2+ ions. In this study, purified bittern was obtained by using dolomite and sulfuric acid to extract MgSO4, which was then used to purify Ca2+ ions. High-purity Mg(OH)2 was synthesized by optimizing the NaOH and NH4OH ratio as an alkaline precipitant. Mg(OH)2 synthesis technology made by effectively removing Ca ions from dolomite and bittern can contribute to domestic pilot production.

This study aims to analyze the traditional attire of four ethnic minority groups in Northeastern China: Daur, Ewenki, Oroqen, and Hezhen, considering their natural environment, lifestyles, and cultural influences. A literature review of academic papers, books, and online resources was conducted, along with indirect investigations through artifacts. The Daur people, being equestrian, have garments with deep slits, vibrant colors, and elaborate decorations. The Ewenki people wear clothes made of fabric in the summer and primarily deer skin in the winter, and their clothing is simple and not flashy. The Oroqen people’s clothing typically has slits at the front, back, or on both sides, and they wear a waist belt. The Hezhen people, an ethnic group that primarily hunts and fishes, wear two-piece clothing with a hip-length top and pants or other fur-trimmed garments. All groups incorporate symbolic patterns influenced by Shamanism, along with animal headgear and leather shoes. We observed that the traditional costumes of ethnic minority groups in Northeastern China share many commonalities in form, but there are detailed differences in material, shape, color, and decoration due to unique geographical and climatic characteristics as well as differences in livelihood. Additionally, the structure of clothing varies depending on each tribe’s shamanistic practices and lifestyle.

This study investigated primary teachers’ knowledge of pronunciation instruction, and its manifestation in classroom practices in Korean EFL contexts. To this end, the questionnaire data collected from 47 teachers were quantitatively analyzed. The emerging themes from 5 teachers’ interviews were qualitatively analyzed, based on content analysis. Findings revealed that they had an appropriate knowledge base of pronunciation teaching, equipped with the better understanding of content knowledge (CK), followed by pedagogical content knowledge (PCK), and technical pedagogical content knowledge (TPACK). No statistically significant difference was found in teachers’ knowledge between males and females, and also between the 4 groups with different teaching experience. They manifested their knowledge mainly acquired from the past course lectures into classroom practices, employing controlled and free practices such as listening and repeating, shadowing, songs, chants, games, and role play, including different types of corrective feedback. Most notably, they integrated role play effectively into classroom practices to improve young learners’ pronunciation in interestprovoking and enjoyable ways.

보행환경은 개인의 영역이자 공공 공간으로서 시민들의 일상생활에 매우 중요한 요소이다. 보행환경의 중요성이 인지되면서 국가적 차원에서도 보행환경 실태조사를 전국 지자체가 5년마다 시행하도록 법으로 규정하는 등 체계적인 실태조사가 필요한 실정이다. 하지만 보행환경에 대한 실태조사는 일부 지역을 대상으로 현장 조사에 의지하는 등 실태조사 방법론에 있어서는 기존의 한계를 벗어나지 못하고 있다. 본 연구는 고해상도 거리 영상과 딥러닝 기술을 활용한 보행환경 평가 지표 개발을 목표로 하였다. 보행환경 평가 지표 개발을 위해 보행환경 평가와 관련된 국내외 문헌 및 딥러닝 기술을 활용한 보행환경 평가 연구를 리뷰를 토대로 보행환경 평가 지표 초안을 개발하고, 도출된 보행환경 평가 지표의 구체적 데이터 구축 가능성을 확인하기 위해 거리 영상의 시멘틱 세그멘테이션(semantic segmentation) 결과 정확도와 영상 외 필요한 자료에 대한 취득 가능성을 검토한 후 최종 보행환경 평가 지표를 제안하였다. 도출된 보행환경 평가 지표는 안전성, 편리성, 쾌적성, 접근성 4개 카테고리에 8개 지표를 활용하는 것을 제안하였다. 본 연구의 결과는 현장 관찰 조사나 설문조사에 기반한 기존 보행환경 연구의 한계점을 탈피하고 고해상도 거리 영상과 딥러닝 기술을 활용한 도시 연구의 지능화 계기를 마련하고 보행환경 평가 업무를 보다 효율적으로 수행할 수 있는 초석이 될 것으로 기대한다.

The degree and intensity of unpleasant and disgusting odors perceived through a person's sense of smell can vary depending on personal or social and cultural characteristics. In addition, it is not effective to manage odors solely on the basis of concentration levels because odors can be combined according to temperature, humidity, and frequency, so that they can be recognized differently even if the same person smells the same substance. The mobile odor application was developed to enable real time monitoring of odor characteristics reflecting the actual condition of the field. Accordingly, the Green Future Foundation, a civic group, conducted an environmental campaign to record and share the information of odors in school zone using the first version of the application. The real time monitoring of field odor was able to improve the problems of the current standard methods for the examination and assessment of odors. However, with regard to the first version of the application, the process and results of odor recording through odor measurement applied the direct olfactory method and were less relevant. Therefore, it was difficult to organize data due to duplicate selection. For that reason, this study was conducted to overcome the problems of the first version of the mobile application and to effectively and accurately reflect odors and personal characteristics. This odor application that has been developed is able to monitor and assess odors based on 5 features: classification, character, strength level, hedonic tone, and acceptability.

This study investigated the odor dilution rate at 15 locations around three schools in Seoul using an onsite olfactometer. In addition, odor intensity, odor quality, and hedonic tone by direct sensory method were measured along with measurement of the field odor dilution rate, and instrument analysis using odor sensor array and TD-GC was also measured. Onsite olfactometer measurements show that only one of the three schools measured odors exceeding the strict emission acceptance standard of 10 at three points. The average odor intensity at each point measured by the direct sensory method of five persons was in the range of 2.7 to 0.3. The difference in the number of odor dilution rates around schools in Seoul could be related to the level of income by region. The odor environment around each school was judged to be well managed in areas with higher income levels, indicating a lower odor dilution rate. The correlation coeffcient between the odor intensity measured by the direct sensory method and the onsite olfactometer was 0.79, indicating high correlation. The correlation coefficient of sensor array and TD-GC toward the odor intensity was -0.28 and 0.02, respectively. This suggests that a method based on a person's sense of smell should be introduced when measuring low-level odor dilution rates in non-industrial areas, such as school zones.

This study examined factors that influence purchase intention of ethically produced fashion products. Theory of Reasoned Action was used to understand consumer attitude formation and purchase intention of ethically produced fashion products. Two unique variables were studied (environmental awareness, environmental concern) with the consumer attitude toward the purchase intention of ethically produced products. The influence of subjective norms on purchase intention was also examined. The results showed the influence of environmental concern on both attitude and purchase intention along with the influence of attitude on purchase intention. The findings of this study contribute to the body of the existing knowledge in the area of ethical production by providing explanations and a broad understanding of the factors that influence purchase intention of ethically produced fashion products. The results will also provide insight to firms wanting to effectively convey pro-environmental efforts to consumers that will help branding, positioning, and potential sales increase.

Autophagy is recently receiving the spotlight as the development strategy for promising anticancer drugs. In particular, the majority of anticancer drugs originating from natural products are known to induce autophagy. Saururus chinensis has been used for treating various inflammatory diseases. Recent research has revealed that the extract of Saururus chinensis possess cytotoxicity for various types of human cancer cells. However, the exact action mechanism of Saururus chinensis extract for oral squamous cell carcinoma (OSCC) has not been studied yet. Therefore, the authors of this research aim to study the effect of methanol extract of S. chinensis (MESC) on OSCC cells. To observe the cell proliferation inhibitory effect of MESC on HSC3 cells, the authors conducted the trypan blue exclusion assay. Also, the action mechanism of MESC was studied by conducting the cell cycle analysis, acidic vesicular organelle (AVO) staining and flow cytometry analysis, monodansylcadaverine (MDC) staining, propidium iodide staining, and Western blotting on MESC-treated HSC3 cells. When HSC3 cells were treated in MESC, the cell proliferation was suppressed in time-dependent and dose-dependent manners. Also, the number of sub-G1 arrested cells increased in a dose-dependent manner. MDC punctate and AVO puncta significantly increased respectively. Western blot analysis demonstrated the expression of autophagy-related proteins increased, but apoptotic proteins were not observed. Also, the pAkt protein was reduced, while the p-p38 protein and pERK protein increased. According to our results, MESC induced autophagy and accompanied changes in the cell cycle in HSC3 cells. Also, the alteration in Akt, ERK, and p38 pathways were confirmed. This result suggested the possibility of MESC as the new promising adjuvant for treating OSCC patients.

As brands’ use of social media to connect with customers becomes increasingly important, there is a need to continually monitor and examine activities in social networks. An important aspect of the social network communications is its unique ways of concentrating and dispersing information among participants (actors) – density and centrality of the network. By looking at both density and centrality, the relationships among actors and their ability to influence others are revealed, allowing deeper understanding into networked behaviors. In this manner, examining whole and ego network patterns, the unique roles of individual actors, can provide brands significant insight in understanding how influencers form and how users connect and spread information. Based on the social network analysis, which represents a combination of theory and analytical methods of networked relationships, this study analyzed Twitter networks of two multi-brand cosmetics and beauty retailers, Sephora (global brand) and Ulta Beauty (U.S. domestic brand). Using NodeXL, daily Twitter data for both brands were gathered to investigate network activities. By examining both ego-networks and the whole networks, the results showed that while ego-networks for brands were quite similar to one another, there was a big difference between the ego-networks and whole networks in regards to the number of actors, type of connectivity, as well as the prominence of brands. Sephora was often not an important part of its hashtag network, and thus was not able to maintain strong control over communications and messages in these networks whereas Ulta maintained its control over its networks. The findings from analyzing these network patterns, the unique roles of individual actors, and the brands within the networks provide significant insights in understanding how influencers form and develop the ability to connect and spread information.
