  • This study analyzed cases that applied hologram technology in the fashion industry in order to provide basic information for research on fashion marketing using hologram technology. The results of this study are as follows. A hologram was applied to fashion businesses in various ways including fashion shows, outdoor signboards, hologram windows or screens in stores, and launching shows or exhibitions. Most of these cases were foreign fashion brands, which utilized hologram technology actively for formulating a new brand image or for advertising products. Among Korean brands, however, there are not many cases of hologram application. Today, as-being the age of smart devices, the mobile advertisement market is growing rapidly among smart phone users. DKNY and Puma are providing information on styling through smart phone applications, and the Adidas stores in Germany also allow the customers to buy goods by entering a simple code through the smart phone. Recently, new devices are being introduced one by one, which display 2D digital contents in 3D holograms by combining mobile and hologram technologies. The marketing of fashion products is not just for supplying products but is required to satisfy the consumers' five senses. Therefore, the development of experiential contents based on the combination of mobile and hologram technologies will open new potential for profitable business models.

  • Objectives: Six cases of non-oral occupational methanol poisoning were found in mobile phone parts manufacturers in South Korea during the period from 22 January 2016 to 5 October 2016. We conducted this study to determine the cause of the accident including social environment factor. Methods: We interviewed the cases. Based on that, we described this poisoning accident narratively and arranged the evolution of the accident in chronological order. We used the Haddon matrix method to investigate the cause of the accident. Results: It was found that six cases were all dispatched workers who were under poor working condition including working time exceeded 12 hours a day, not given basic occupational health and safety information etc. Occupational disease associated with dispatched work was difficult to be reported. 2 cases were not able to identify the cause of the disease within one year. Conclusions: In short, the direct cause of the poisoning accident was that workers were exposed to high concentration of methanol(over 1,000 ppm). One of the main fundamental cause is that dispatched worker is rampant in the supply chain of mobile phone production. To protect dispatched workers, appropriate occupational safety health measures are needed urgently.

  • A lot of researchers have been interested in the factors influencing the use of mobile phone services. Most of the previous studies, however, verified only the research models developed by the authors. They did not consider which model agrees better with the real situation. This study presents six alternative models based on various previous studies, and compares the data fitness of the models. A Web survey of mobile phone users collected 2,217 cases. Statistical analyses, using SEM (Structural Equation Modeling), show that the fitness of the simplest alternative model is better than that of any other model. The simplest model has no causal relationship among exogenous factors, and proposes that all of exogenous factors have direct impacts on the customer satisfaction. In addition, the analyses say that corporate and brand image and additional service are more important than the other exogenous factors such as communication quality.

  • The development of mobile communication technology is transforming the market of mobile communication devices, which is used to be merely for simple communication, into the one which offers features of personal digital assistant (PDA), fax communication and Internet access. Unlike a mobile phone which comes out as a complete package and whose functions cannot be changed, a smart phone can be upgraded by its user, adding or removing apps as he pleases. OS's of smart phones are iOS-based Apple, Google Android, Window Mobile, and others. Due to its convenience and powerful features, many people use smart phones its high price. On the other hand, consumer complaints are rising on poor A/S for occasional malfunction. This study analyzes how A/S cases can be classified into groups according to quality factors. We evaluate factors such as consumer impression and consumer satisfaction. By dual quality evaluation using KANO method, we would like to show the different A/S strategy for smart phones, compared with mobile phones.

  • The purpose of this study is to identify the types of consumer problems involving the use of online game services in Korea. This study analyzed the consumer damage cases by age and type that were reported to the Korea Consumer Protection Board (KCPB). The results of this study are as follows: The online game complaints varied by age. In the case of children, most complaints involved phone charging online game fees without parents' consent. There were similarities in the victimization of teens and children according to reason for complaint, handling result and type of damage. However, based on method of charging, mobile phone and credit card payments were causes in the case of teen victimization. Meanwhile, complaints among adults showed more complexity than the previous two groups such as cases relating to online game companies illegally seizing game items and game accounts, and charging fees for unused services caused by identity theft. By type of charging method, most complaints involved phone and mobile phone payments. According to the analysis result of online game victims, the monetary damage of consumers did not differ among socio-demographic variables such as age, residence, gender and occupation but there was difference in the method of charging. In the handling period, differences could be seen by age, year, gender and type of damage.

  • Adoption of wireless communication facilities in mobile devices leads to increased vulnerability in individual privacy. One of such cases was discovered when a smart mobile phone of Paris Hilton at Oscar Award Ceremony was hacked a Swedish group of hackers. In this study, I wondered what sort of personal information could be exposed to hackers in such cases. In the course of survey, it was recognized that technical analysis of flash memory in mobile devices to check what kinds of data are stored there is technically almost impossible, since they are usually built in a proprietary manner. No generic tools could apply to discover their contents. Having recognized technical difficulties, it was inevitable to resort to a questionnaire survey to see awareness level with regard to personal privacy. We collected response from three hundred respondents by posting the questionnaire at World Survey on-line research site. What we have discovered was quite astonishing that even personal residence registration numbers have been found from nine of every ten respondents. Other data revealed include phone numbers, names, and personal bank accounts.

  • Objectives: To introduce a protocol of Mobi-kids study which was aimed to examine an association between radiofrequency (RF) radiation exposure by mobile phone use and brain tumor risk in children and adolescents. Methods: The Mobi-kids study was a multinational matched case control study using a standardized protocol with the number of subjects targeted about 1,000 cases and 2,000 controls aged 10 to 24. In Mobi-Kids Korea, the source population was restricted to Seoul, Incheon, and Gyeonggi-do province. Eligible cases of primary brain tumor (glioma, meningioma, and others) were diagnosed from January 2012 to June 2015. Eligible controls were appendicitis patients operated during the study period. Two controls were matched on age, gender, and study region for 1 case. Information about pattern and history of mobile phone use and other covariates were obtained by face to face interview by trained interviewer. The Mobi-kids study has been involved in Mobi-expo as a validation study about mobile phone use, XGridmaster to localize tumor in the brain for RF energy calculation, and histological review for validation of diagnosis. Results: The Mobi-kids was the first and largest study in children and adolescents to estimate risk of brain tumor in association with the RF energy absorption in the brain estimated by mobile phone use. Forty-six-cases and 54 controls were collected as of September 2014 in Korea. Conclusions: The meaningful results of the study were expected because of the largest sample size, high validity of EMF exposure assessment as well as the susceptible study populationof children and adolescents.

  • The importance of User Interface (UI) in mobile phone has increased as the complexity of use increases due to the new technology adoption. The complexity and load for user interface development has increased accordingly. This paper discusses how to make a structured UI development process based on the mobile phone UI development case. After the review of UI development process and issues arising during the development, four levels of user interface guidelines are proposed such as macro rules, action templates, application rules and interaction cases. The importance of dealing various interaction case is emphasized which is not referred in the present industry UI guidelines. Most of research related to UI development focus on the target product rather than how to make good UI process. Based on the good UI process, good UI of the product can be realized. This proposed process based on UI guidelines will help to step up the UI development of mobile phone industry. Also, this process can be applied to different products or services.
