More flexible learning models are needed, and learning environments that operate through mobile technologies such as portable multimedia players(PMP) provide useful tools in implementing these learning models. The main attractant of PMP is often their versatility: being able to load and play different formats of video, audio, digital images, and interactive media. In this paper, we investigate the factors influencing the usage and acceptance of the PMP for study, based on the extended version of the Technology Acceptance Model (TAM). Based on data collected from online survey, we show that perceived usefulness, perceived ease of use, flow and perceived enjoyment are the major determinants for users to play PMP for study purpose. Factors, including ease of use, contents-credibility are shown to determine the level of perceived usefulness; additionally, perceived usefulness, ease of use and perceived enjoyment are shown to directly affect the level of flow. Based upon the statistical results, some useful guidelines for developing learning contents are also provided.

Despite the fact that navigation technology and educational programs were developed and maritime law has been enforced strictly, the number of maritime accidents has not dropped significantly. In order to reduce traffic accidents at sea, the preventive index for maritime accidents is designed and measured to evaluate and visualize the activities performed. The survey module is composed of preventive domains such as education, engineering, enforcement and information. The index was abstracted from the statistics of maritime accidents causes(2010~2012). It can be evaluated by using the newly developed survey modules. It was found that there is some correlation between the index value and the accident rate of maritime traffic. It is expected that this index will become another useful tool to help prevent maritime accidents.

This study analyzed the types of scientific emoticons made by science-gifted elementary school students and their perceptions on making scientific emoticons. To do this, 71 students from 4th to 6th graders of two gifted science education center in Seoul were selected. Scientific emoticons made by the students were analyzed according to the number and types. Their perceptions on making scientific emoticons were also analyzed through a questionnaire and group interviews. In the analyses for types of text in the scientific emoticons, 'word type' and 'sentence type' were made more than 'question and answer type'. And the majority of students made more 'pun using pronunciation type' and 'mixed type' than other types. They also made more 'graphic type' and 'animation type' than 'text type' in the images of the scientific emoticons. In the analyses for the information of the scientific emoticons, 'positive emotion type' and 'negative emotion type' of scientific emoticons were made evenly. The students made more 'new creation type' than 'partial correction type' and 'entire reconstruction type'. They also used scientific knowledge that preceded the knowledge of science curriculum in their grade level. The scientific knowledge of chemistry was used more than physics, biology, earth science, and combination field. 'Name utilization type' was more than 'characteristic utilization type' and 'principle utilization type'. Students had various positive perceptions in making scientific emoticons such as 'increase of scientific knowledge', 'increase of various higher-order thinking abilities', 'ease of explanation, use, memory, and understanding of scientific knowledge', 'increase of fun, enjoyment, and interest about science and science learning', and 'increase of opportunity to express emotions'. They were also aware of some limitations related to 'difficulties in the process of making scientific emoticons', 'lack of time', and 'limit that it may end just for fun'. Educational implications of these findings are discussed.

Satellite-derived data is collected by observing the Earth and is used in various fields such as national defense, natural disasters, location-based services, infrastructure, environment, energy, marine, and insurance. This study aims to present the virtuous cycle structure of the satellite information data industry and the business ecosystem model of the industry. As a research method, cases were collected and categorized from the following areas: literature, online, application, and content. The results show that the ecosystem model of the satellite information data industry provides an approach to content services in public and commercial areas, and develops various algorithmic technologies to facilitate content production and services at the level of complex general-purpose technologies. Second, in terms of content typology, satellite information data can be subdivided into monitoring content, urban space monitoring content, and satellite information content. Third, the consumption value of satellite content could be subdivided into informational value, environmental, social and governance (ESG) value, educational value, and content value. In order to expand the global content market, Korea will need to focus on creating an ecosystem for the satellite information industry and discovering differentiated content. It will also need to increase the popularization and accessibility of data to the general public and promote the Korean K-Satellite Information Data Industry ecosystem through government support, policy efforts, and policies such as establishing legal systems, increasing investment, and training human resources.

Despite the importance of the program development activities and the necessity of the systematical investigation on the features of the program development activities in the social service agencies, it has been observed that recent social work studies have ignored an important study area of program development, including the activities of collecting data in the process of program development in social service agencies. Therefore, this study was undertaken to investigate salient features of the activities of collecting data for program development in the social welfare centers in Korea. A questionnaire was constructed with three parts, including a dependent variable and 6 independent variables, and 201 questionnaires were collected from 353 agencies during two months. As the result of the descriptive analyses, the five noticeable features were found, (1) the activities of collecting data for program development in the agencies are very active; (2) staff in his/her twenties are in charge of program development; (3) diverse data are collected in the process of program development (4) hard data are more collected than soft data in the process of program development; (5) the respondents are more despondent on knowledge learned from individual studies than knowledge learned from academic institutes. Multiple regressions were applied to analyze the relationship between independent variables and three kind of dependent variables - total feature of data collecting, collecting hard data, collecting soft data. The result showed that the total feature of data collecting was critically influenced by social workers' autonomy, openness, and knowledge learned from academic institutes, and workload. The activities of collecting hard data was influenced by the above variables, except social workers' workload, The activities of collecting soft data were influenced by the social workers' autonomy, openness, and knowledge learned from academic institutes, and workload. Major findings were discussed and several suggestions were made for future research and improvement of the program development in social welfare centers.
