  • Purpose: This study analyzes automobile quality review data to develop alternative analytical method of informal data. Existing methods to analyze informal data are based mainly on the frequency of informal data, however, this research tries to use correlation information of each informal data. Method: After sentimental analysis to acquire the user information for automobile products, three classification methods, that is, $na{\ddot{i}}ve$ Bayes, random forest, and support vector machine, were employed to accurately classify the informal user opinions with respect to automobile qualities. Additionally, Word2vec was applied to discover correlated information about informal data. Result: As applicative results of three classification methods, random forest method shows most effective results compared to the other classification methods. Word2vec method manages to discover closest relevant data with automobile components. Conclusion: The proposed method shows its effectiveness in terms of accuracy and sensitivity on the analysis of informal quality data, however, only two sentiments (positive or negative) can be categorized due to human errors. Further studies are required to derive more sentiments to accurately classify informal quality data. Word2vec method also shows comparative results to discover the relevance of components precisely.

  • Objective: This study examined the change of informal labeling self-respect, depression/anxiety, and aggression of adolescents over time and relationship between the intercept and the growth of the variables. Method: 4-year longitudinal panel data(n=2,699), Korea Youth Panel Survey (KYPS), were analyzed to verify the influence of informal labeling on self-respect, depression/anxiety, and aggression of adolescents. Through latent growth modeling, temporal change of the variables was examined. Results: Analytic results are as follow. First, the initial status of informal labeling had a negative impact on the initial status of self-respect. The slope of informal labeling also had a negative impact on the slope of self-respect. In contrast, the initial status of informal labeling did not have an significant impact on the slope of self-respect. Second, the initial status of informal labeling had a positive impact on the initial status of aggression. The slope of informal labeling had a negative impact on the slope of aggression. In contrast, the initial status of informal labeling did not have an significant impact on the slope of aggression. Third, the initial status of informal labeling had a positive impact on the initial status of depression/anxiety and a negative impact on the slope of depression/anxiety. The slope of informal labeling had a positive impact on the slope of self-respect. Conclusions: The results suggest the importance of informal labeling on self-respect, depression/anxiety, and aggression of adolescents.

  • Building on previous literature of human resource management and development, this paper investigates the effect of various characteristics of informal education a firm offers on employees' individual creativity. we identify quantity, quality, and variety as three critical components of informal educational and training circumstances. Data from a multi-informant survey conducted to 442 employees in Korean postal service show that a firm's informal educational training has significant effects on its employee creativity. The results indicate that enough high quality of program, various training method have a positive relationship with his/her individual creativity although time and opportunity don't have an critical impact on employee creativity. This study highlights the importance of a firm's informal education in terms of motivation and skills, and helps to explain individual discrepancies in creativity.

  • This study investigated what kind of informal knowledge is emergent and what role informal knowledge play in process of solving 2-digit by 2-digit multiplication task. The data come from 4 times interviews with a 3th grade student who had not yet received regular school education regarding 2-digit by 2-digit multiplication. And the data involves the student's activity paper, the characteristics of action and the clue of thinking process. Findings from these interviews clarify the child's informal knowledge to modeling strategy, doubling strategy, distributive property, associative property. The child formed informal knowledge to justify and modify her conjecture of the algorithm.

  • To date, the literature has focused on formal R&D activities, such as internal, joint or external R&D, but informal R&D activities, such as job training or design, can also have a positive impact on technological innovation. To address this research gap, this paper examined 1) the influence of informal R&D activities on innovation adoption, and 2) the differences between formal R&D-oriented and informal R&D-oriented firms in process and product innovation. For this, statistical analysis was conducted using the data set from 2012 Korea Innovation Survey. The results suggest that 1) informal R&D activities can influence process innovation, and 2) firms engaging in both informal and formal R&D actively adopt product innovation. Findings suggest that 1) firms should recognize the importance of informal R&D and 2) national R&D policy should reflect the positive role of informal R&D in technological innovation.

  • Purpose - This paper explores the perceptions held by native grocery shop-owners of their foreign counterparts to ascertain if there are lessons to be shared especially regarding operational/survival strategies. Research design, data and methodology - A questionnaire was used to collect data from 121 subjects who were purposively selected. The data was processed and analysed with the aid of Statistical Package for the Social Sciences(SPSS) software. Results - The study found that native South Africans hold the perception that immigrants have operational advantage over them. The study also found that with bulk buying, immigrants' stores stock a larger variety of groceries while their items are sold cheaper. It is also arguable from the standpoint of the findings that immigrant grocery store owners avoid expensive lifestyles which often is common among natives who own informal grocery shops. Conclusions - It is the position of this paper that adopting the strategies utilized by immigrant entrepreneurs, informal grocery shops owned by native South Africans are likely to see an improvement in their township-based grocery stores. A major merit of this study beyond its novelty is its potential to advance learnership and collaboration between immigrant entrepreneurs and their native counterparts.

  • Although science continues to be a key subject in the education of the majority of young people throughout the world, it is becoming increasingly clear that school science is failing to win the hearts and minds of many of today's younger generation. Researchers have begun to look at ways in which the learning that takes place in museums, science centres and other informal settings can add value to science learning in schools. Four case studies are used to illustrate the potential afforded by informal contexts to research aspects of science learning. The case studies involve: the European Union PENCIL (Permanent European Resource Centre for Informal Learning) project (a network of 14 museums and science centres working with schools to enhance learning in maths and science); a large natural history museum in England; the Tate Modernart gallery in London, and the Outdoor Classroom Action Research Project which involved researchers working in school grounds, field centres and farms. The range of research questions that were asked are examined as are the methodological approaches taken and the methods used to collect and analyse data. Lessons learned from the studies about research in the informal contexts are discussed critically.
