Purpose - Recognizing the importance of small and medium enterprises and venture enterprises for the domestic economy, the purpose of the present study is to select factor termed export modes from among various export success strategies and factors that can help those enterprises secure export competitiveness in the world market to analyze the effects of export modes on the amounts of exports and periods until export after the foundation of those enterprises. Research design, data, and methodology - A structured questionnaire was used as a tool to derive the purpose of the study, and a questionnaire survey was conducted using a mobile survey technique that facilitated the distribution of questionnaire sheets and the collection of results. The main methodology used is crossover analysis, and the regression analysis technique was applied to verify the study results derived, thereby securing the reliability and validity of the final results derived. Results - Small and medium venture enterprises with shorter periods of time until the first export success after establishment adopted direct export modes more frequently, and those enterprises with larger amounts of the first export after establishment adopted direct export modes more frequently. The results of quantitative analysis, indicating that 66.1% of those enterprises with an export amount exceeding one billion won adopted direct export modes, can be said to support the foregoing. The crossover analysis results derived as such were reanalyzed using the PPML regression analysis technique to quantitatively identify that the amounts of the first export of enterprises that adopted direct export modes were larger than those of enterprises that adopted indirect export modes by 120%. Conclusions - The present study implies differentiated values in three aspects. First, the present study investigated and presented the export success factors and strategies of small and medium venture enterprises in a total of 14 countries in the Asian region, European region, North American region, African region, and South American region. Second, it intensively investigated five export modes to identify and verify that they were affecting the export success of small and medium venture enterprises. Third, based on the results of the investigation, the present study presented two marketing implications in the pragmatic aspect.

As the COVID-19 pandemic continues to prolong, non face-to-face, online classes has become the new normal in education. To examine the effect of course types and course delivery modes on student course satisfaction, the study analyzed survey data collected from 2,743 students enrolled in a 4-year university located in a metropolitan area. Basic Frequency analysis as well as keyword network analysis were used to analyze student survey data. The main results and implications of the study are as follows. First, the survey results indicated that students preferred asynchronous classes over synchronous online classes. This tendency was consistent regardless of student grades and majors as well as the course type. However, students majoring in more practice-oriented disciplines tend to prefer synchronous online classes and blended classes, and this tendency gets stronger with courses in major. Second, the keyword network analysis results further indicated that interactivity may play an important role in both synchronous and asynchronous online course satisfaction.

An extensive body of research on the effects of country-of-origin has emerged in the international marketing and business literature streams. Nonetheless, extant studies do not satisfactorily demonstrate whether and how a foreign firm's choice of market entry mode influences consumers' purchase intentions of its product in country-related affect contexts. Using a survey and an experimental design, we aimed to provide evidence of the effects of the choice on consumers' evaluation and attitude of its product in an animosity context and in a national image context. Through the survey, we collected data regarding consumer animosity, national image, product evaluation, and product attitude from 185 university students and tested the hypotheses that consumer animosity and national image have effects on foreign product evaluation and attitude. The results of the survey research show that personal animosity has a negative effect on consumers' evaluation of foreign products and that a country's image regarding economics has positive effects on consumers' attitude toward foreign products as well as consumers' evaluation of foreign products. In the experimental design, we divided subjects into four groups and exposed them to several descriptions of hypothetical purchase situations. Conducting a 2 (market entry modes)${\times}2$ (country-of-origin) ANOVA, we tested the hypothesis that a market entry mode influences foreign product evaluation and attitude. The results of the experimental study reveal that in a high country-related product association (Germany), market entry modes have insignificant effects on foreign product evaluation and attitude. In addition, in a low country-related product association (China), international partnership has more positive effects on foreign product evaluation and attitude than does exporting.

Objective: The objective of this study was to examine multi-modal interaction effects of input-mode switching on the use of smart phones. Background: Multi-modal is considered as an efficient alternative for input and output of information in mobile environments. However, there are various limitations in current mobile UI (User Interface) system that overlooks the transition between different modes or the usability of a combination of multi modal uses. Method: A pre-survey determined five representative tasks from smart phone tasks by their functions. The first experiment involved the use of a uni-mode for five single tasks; the second experiment involved the use of a multi-mode for three dual tasks. The dependent variables were user preference and task completion time. The independent variable in the first experiment was the type of modes (i.e., Touch, Pen, or Voice) while the variable in the second experiment was the type of tasks (i.e., internet searching, subway map, memo, gallery, and application store). Results: In the first experiment, there was no difference between the uses of pen and touch devices. However, a specific mode type was preferred depending on the functional characteristics of the tasks. In the second experiment, analysis of results showed that user preference depended on the order and combination of modes. Even with the transition of modes, users preferred the use of multi-modes including voice. Conclusion: The order of combination of modes may affect the usability of multi-modes. Therefore, when designing a multi-modal system, the fact that there are frequent transitions between various mobile contents in different modes should be properly considered. Application: It may be utilized as a user-centered design guideline for mobile multi modal UI system.

The purpose of this paper is to get a powerful tool for response analysis of a spherical dome subjected to dynamic excitation based on mathematically analytical method, i. e., the Galerkin procedure in modal analysis, with sufficient accuracy and practicality. At first, this paper provides an approximate solution of eigen modes, which has sufficient accuracy and praticallity for response analysis in symmetric and antisymmetric state. In the second stage of this paper, response analysis of a dome subjected to horizontal earthquakes is executed as the application of these approximate modes. Many important response characteristics may manifest themselves through parametric survey of material and geometric properties.

The rise and fall of social research methods rely on how much a certain method is able to appropriately reflect the change of society. The present research proposes new mobile surveying methods, considering the current and future trends in Korea. In particular, this research focuses on environmental pressure (time constraints, the presence of others and the place) as one of the major factors influencing the effects of survey modes. For example, landline surveys are conducted in the respondent's home, which is a private and fixed space. On the other hand, surveys on mobile phones can be conducted in diverse places with other people around. After sampling 500 landline respondents and 500 mobile phone respondents using a quota method, the same questionnaire was used for both the mobile and landline interviews. The findings are generally consistent with the literature supporting the data quality and comparability of the mixed mode survey. These results are encouraging for researchers designing surveys that feature mobile phone data collection.

This study aims to monitor the variation of modal frequencies of steel buildings during their construction sequence. In this respect, construction of a steel building is followed by vibration based measurements. The monitored building is a three-story educational building within a building group whose structural system consists of steel moment resisting steel frames and eccentric braces. Five different acceleration measurements in two perpendicular directions are taken on five different construction stages, starting from the erection of the columns and beams ending with the completion of the construction. The recorded measurements are transferred into frequency domain and the dominant frequencies for each case have been determined. The change in the dominant frequencies is evaluated with the existing construction stages and performed constructional works between the stages. The last measurement, performed on the building in service, revealed the first two dominant frequencies as mutual in X and Y direction, showing that these dynamic modes are torsional modes. This result is investigated by numerical analysis performed with finite element model of the building constructed for design purpose. Lower frequencies and different mode shapes are determined from numerical analysis. The reason of lower frequencies is discussed and the vibration survey is extended to determine the effects of an adjacent building. The results showed that the building is in strong relation with an adjoining building in spite of a designed construction joint.
