  • The response characteristics of the forced vibration generated when the high-damped vehicle pass the bumped barrier was studied, and in particular, the response behavior of displacement, velocity and acceleration was analyzed for the forced vibration model. In addition, in order to obtain responses such as displacement, velocity, and acceleration, a numerical analysis technique of the Runge-Kutta-Gill method was performed in time domain. The response was successfully obtained in detail under several high damping conditions. As a numerical analysis result, the response of the vehicle was obtained by considering the vehicle body to which the impulse impact was applied. Also, the analysis result was compared with the experimental result in order to verify the validity of vehicle model. The amplitude and natural frequency of the vehicle were considered and analyzed. The Nyquist diagram of the vehicle model was also obtained and the relationship could be analyzed. And the vibration response was analyzed on different mass, damping and stiffness.

  • The purpose of this research is to analyze how the Chinese cosmetics certification system works as a Non-Tariff Barriers(NTBs) for Korean exporting companies to access the Chinese market. China is the largest market for Korea's cosmetic exports, but China's policy of protecting domestic industry has become a barrier to Korea's cosmetics exports to China. Therefore, this research, through the analysis of regulations of the Chinese certification system for imported cosmetics. revealed that there are such problems as ① information leakage ② duplication of inspection ③time delay. In order to verify those problems, surveys and face-to-face interviews with Korean cosmetic exporting companies to China have been conducted. In conclusion, Chinese cosmetics certification system not only protects its own industry, but also serves as a NTBs to disturb the access of imported cosmetics to the Chinese market in order to foster Chinese cosmetic industry.

  • Information-security management systems (ISMSs) are becoming very important, even for micro, small, and medium enterprises (MSMEs). However, implementing an ISMS is not an easy task. Many obstacles must be overcome, e.g., complexity, document tracking, competency management, and even changing cultures. The objective of our study is to provide ISMS application tools, based on ISO 27001:2013 ISM frameworks. The application was developed on the Odoo Open Enterprise Resource Planning platform. To validate its feasibility for future improvement, the application was implemented by an MSME company. For this implementation, information-security-related users gave their feedback through a questionnaire. The distributed feedback questionnaire consists of nine assessment parameters, covering topics from the application's technical aspects to users' experiences. Based on the questionnaire feedback, all users of the application were satisfied with its performance.

  • This study adopted the descriptive survey research method. The population of this study comprised of the hearing impaired students in selected government secondary schools in Rivers state. The population of hearing impaired students in Rivers State is 257. A simple random sampling technique was used to select a sample size of 159. A self-developed instrument titled "Availability and Utilization of Library Information Resources Questionnaire (AULIRQ)" was utilized for data collection. 153 responses were collated, indicating a 96.2% response rate. The data collected was arranged and analyzed using frequency count, percentages, and mean and standard deviation. Finding reveals that information resources in the libraries understudied were inadequate and under-utilized. Also, it was established that among other barriers, under-funding is a major barrier to making information resources available for the physically challenged. It was recommended that schools offering special education for the hearing impaired should pace up in their developmental gap by providing such resources and ensure adequate funding by all stakeholders.

  • In current information society, there is a barrier called digital divide. Due to this barrier, the disabled have difficulties to communicate with the world. Recently, with advanced smart techniques, smart devices become necessity for the disabled. Currently improvements of smart application accessibility become a great concern for the disabled. The purpose of this paper is to present some guidelines for enhancing smart application accessibility for the disabled. The enhancement guidelines are developed based on the existing mobile accessibility guidelines and modified for better adaptability for the disabled. Our principles are as follows: minimizing blue light emission from smart devices, automatic focus on input window, action trace, font color change, emergency notification by motion, gesture recognition, control location, scrolling avoidance, auditory service for visual warning, and icon literation.

  • The purpose of this study is to provide a cultural and artistic content guide service that can provide customized guides according to the disability status of the disabled who consume cultural and artistic contents. It is designed to provide a more individualized service through user input of disability information including the type and degree of disability of the disabled, the type of cultural and artistic content desired by the disabled, and information on the cultural and artistic level of the disabled. In addition, it is not limited by time and place, and it has the distinction of providing appreciation of cultural and artistic contents and commentary information of the corresponding cultural and artistic contents in various ways on the application. In particular, to provide cultural and artistic contents differently by identifying the type or degree of disability of the user, or to provide cultural and artistic contents with different expertise in consideration of the user's cultural level and taste, and to improve the cultural level. The most special feature is that it provides recommended content in consideration of the difficulty of art content. User analysis was conducted through in-depth interviews and persona techniques. As a result of the analysis, the needs for the enjoyment of culture and arts are also increasing among the disabled, while the services that reflect those needs are very insufficient. Therefore, all interviewees stated that they are willing to actively utilize these services if they are released. In the future, it is necessary to increase the accessibility of the disabled to culture and arts by developing various services using new ICT technologies.

  • The purpose of this research is support blind person's daily walking. In order to achieve the purpose, we investigate how the environmental information is used for their daily walking both in residential and commercial areas considering the characteristics of walking. In the investigation, interview to the persons concerned is carried out and all the conversation with them is recorded with a voice recorder. Moreover, the environmental information that may become clues is plotted on a map together with photos. The results are as follows; (1) Environmental information which the blind persons use is different depending on the role of its own of place, such as place confirmation, direction decision, distance understanding. (2) It is demonstrated that the information acquisition from sound is effective when they especially understand place and location.

  • In the present competitive organizational environment more organizations are implementing knowledge management initiatives to gain strategic advantage. One such initiative is that of implementing electronic knowledge repositories (EKR) which often leads to a rapid increase in the quantity of information employees have to process daily; raising concerns of employees being overloaded. This is especially true for current EKRs using distributive technology, enabling customizable individual workspaces which can result in loose knowledge structures. This paper identifies a new type of information overload (IO), extending the concept as occurring in both knowledge seekers and contributors and uses cognitive dissonance theory to provide evidence that IO can change employees' perception of EKR usage. This research paper provides the first empirical evidence that overload has no sufficient affect on EKR continuance intention directly, but has significant negative affect on the two main success measures; perceived usefulness and satisfaction of the system.
