Purpose: The main objective of this research is to encourage the increase of local MSME businesses through the sustainable tourism sector in South Sulawesi by proposing a research model that focuses on increasing revisit intention. This, in turn, is expected to stimulate local trade and strengthen tourism attractiveness. Research design, data and methodology: A quantitative research method involving 190 domestic tourist respondents was employed, utilizing a questionnaire for data collection. Structural Equation Modeling (SEM) analysis through AMOS software was applied, and the Sobel test to assess indirect effects. Results: The research findings indicate that memorable customer experiences and travel motivations significantly influence destination image. However, travel motivation does not significantly affect revisit intention. Furthermore, memorable customer experiences and destination image significantly impact revisit intention. Notably, destination image plays a significant mediating role in the relationship between travel motivation and increased revisit intention. Conclusions: Memorable customer experiences and travel motivations directly contribute to the formation of a more positive destination image. Furthermore, memorable customer experiences drive the revisit intention, but travel motivation is not significant. Memorable customer experiences only influence revisit intention through the formed destination image. Additionally, the improvement of memorable customer experience and destination image increased revisit intention.

Improving the microstructure of NiO/YSZ is one of several approaches used to enhance the electrical and mechanical properties of an anode support in Solid Oxide Fuel Cells (SOFCs). The aim of the work reported in this paper was to predict the relationship between these microstructural changes and the resulting properties. To this end, modification of the anode microstructure was carried out using different sizes of Poly (Methyl Methacrylate) (PMMA) beads as a pore former. The electrical conductivity and mechanical strength of these samples were measured using four-probe DC, and three-point bend-test methods, respectively. Thermal etching followed by high resolution SEM imaging was performed for sintered samples to distinguish between the three phases (NiO, YSZ, and pores). Recently developed image analysis techniques were modified and used to calculate the porosity and the contiguity of different phases of the anode support. Image analysis results were verified by comparison with the porosity values determined from mercury porosimetry measurements. Contiguity of the three phases was then compared with data from electrical and mechanical measurements. A linear relationship was obtained between the contiguity data determined from image analysis, and the electrical and mechanical properties found experimentally. Based upon these relationships we can predict the electrical and mechanical properties of SOFC support from the SEM images.

렌즈 절삭공구의 기계적 특성을 향상시키는 기구에 관한 연구를 하기 위해, 탄화규소와 탄화티타늄을 주재료로 사용되었다. 또한, 소결첨가제로 알루미나와 이트리아를 첨가하였다. 첨가제 조성비는 알루미나와 이트리아비를 1:1로 유지하였다. 이를 $1810^{\circ}C$에서 1시간 일축가압 소결 후 $1860^{\circ}C$에서 3, 6 그리고 12시간 동안 열처리하였다. 열처리 시간이 길어질수록 입자크기는 점점 증가하였다. 미세구조는 주사전자현미경으로 관찰하였으며 이미지프로그램(Image-Pro Plus, Media Cybernetics, Maryland, U.S.A.)으로 상분석 하였다. 파괴기구는 주로 길게 자란 탄화규소 입자에 의한 균열회절에서 일어나고 있음을 알 수 있다. 균열회절기구에 영향을 미친 SiC입자들은 대부분 두께가 $2.3{\mu}m$ 이하였고, 장경비는 2.5 이상이었다. 균열가교도 일부 파괴인성 증진기구에 기여함을 알 수 있다.

To characterize the coating structure, diverse methods such as mercury intrusion, nitrogen adsorption and oil absorption methods have been developed and widely employed. These indirect techniques, however, have some limitation to explain the actual coating structure. Recently microscopic observation methods have been tried for analyzing structural characteristics of coating layers. Preparation of the undamaged cross section of a coating layer is essential for obtaining high quality image for analysis. In this study, distortion-free cross-section of the coating layer was prepared using a grinding and polishing technique. The coated paper was embedded in epoxy resin and cured. After curing the resin block it was ground with abrasive papers and then polished with diamond particle suspension and nylon cloth. Polished coating layer was sufficient enough to obtain undamaged cross sectional images with scanning electron microscope under backscattered electron image mode. In addition, the SEM images allowed distinction of the coating layer components. Also S/B latex film formed between pigment particles was visualized by osmium tetroxide staining. Pore size distribution and pore orientation were evaluated by image analysis from SEM cross-sectional images.

본 연구에서는 복합막의 물성향상을 위해 clay를 도입한 polysulfone 나노섬유 복합막을 제조하였다. Polysulfone/clay 복합막은 clay가 들어간 N,N-dimethyl acetamide와 acetone 혼합용매에 polysulfone을 첨가한 후 전기방사법을 이용하여 제조하였으며, 제조된 나노섬유 복합막은 적층수를 변화해 기공크기를 조절한 후 사용하였다. 전반적인 분리막의 특성은 SEM, contact angle, 기공특성, tensile strength, water flux 분석을 사용하여 고찰하였다. 특히 SEM image로 clay의 도입을 확인하였으며 contact angle 측정을 통해 표면이 개질된 결과를 확인할 수 있었다. 그리고 clay의 도입량에 따른 복합막의 기계적 물성을 확인하였다. 따라서 본 연구에서 제조된 분리막은 수처리용 분리막으로 충분히 활용 가능할 것으로 판단된다.

본 연구는 국산 솜대와 인도네시아산 TALI를 원료로 하여 제조한 Zephyr의 기본조직특성을 SEM관찰 및 화상분석법을 이용하여 조사하였다. SEM관찰의 결과, 국산 솜대 Zephyr 의 형태는 유관속초를 구성하는 후벽섬유의 세포벽이 두껍고 세포내강이 거의 없으며 조직이 치밀하였다. 세포간층의 분리가 어렵기 때문에 유관속초간의 집단적인 할렬이 두드러졌고 할렬형태가 균일하지 않았다. 이에 비해 인도네시아산 TALI Zephyr의 형태는 유관속초를 구성하는 후벽섬유의 세포벽이 얇고 세포내강이 크며 세포간극이 많아 세포간층의 분리가 쉬웠으며 가늘고 균일하게 할렬되었다. 화상분석법으로 두 죽종의 횡단면상의 유관속초용과 이들을 구성하는 후벽섬유의 세포벽율을 조사한 결과, 국산 솜대의 유관속초율은 인도네시아산 TALI보다 낮았지만, 후벽섬유 세포벽률은 더 높았다. 이상의 결과로 국산 솜대와 인도네시아산 TALI는 유관속초를 구성하는 후벽섬유의 양과 분포양식의 차이에 의해 제조된 Zephyr의 형상에 차이가 있음을 알 수가 있었다.

Purpose - This study aims to investigate the effect of brand image and trust of a home meal replacement (HMR) industry on customer satisfaction and repurchase during online shopping. Research design, data, and methodology - With 217 questionnaires, this study was conducted by AMOS 20.0, and the Structural Equation Model (SEM) as statistical method was used for examining the hypotheses in this study. Factors such as brand image and brand trust in customer shopping for HMR products online were tested, and relationships between satisfaction and repurchase were studied. Results - Brand image and brand trust in terms of online shopping for HMR were found to affect satisfaction significantly; in addition, the path where satisfaction leads to repurchase was found to be significant. However, brand image and brand trust for HMR in online shopping differed depending on customer age groups. The path-coefficients from brand image of HMR in online shopping to satisfaction were more significant in the older age group; meanwhile, the path-coefficient from brand trust to satisfaction was significant in the younger age group. Conclusions - Results of the study suggested the importance of the attributes for buying HMR products online and provided meaningful implications of difference between age groups when they choose the products.

This study is conducted to fill the research gap in proposing and testing the relationship between "Attitudes about the overall image of the destination", "Subjective norms" and "Perceived behavioral control". Simultaneously, we examine the relationship between these variables and tourists' "intent to choose a destination.". While most previous studies only deal with the relationship between destination image and intended behavior of tourists, this study uses the theory of planned behavior (Ajzen, 1991) to explain the intended behavior of tourists. In addition, the Theory of Destination Image (Echtner & Ritchie, 1991) is used to explain the factor "attitudes about the overall image of the destination", contribute to supplementing and perfecting the Theory of Planned Behavior. This study uses a Structural Equation Modeling (SEM) to analyze a sample of 993 observations, the subjects of which are international tourists to Vietnam, to test the relationship between second-order constructs. The test results show that "Subjective norms" and "Perceived behavioral control" have an impact on "Attitudes about the overall image of the destination". Moreover, all these three factors have an impact on "Intent to choose destination", in which the factor "Perceived behavioral control" has the greatest impact on "intention to choose destination".
