  • Due to global issues such as climate crisis and rising energy costs, there is an increasing focus on energy conservation and management. In the case of South Korea, approximately 53.5% of the total energy consumption comes from industrial complexes. In order to address this, we aimed to improve issues through the 'Shared Network Utility Plant' among companies using similar energy utilities to find energy-saving points. For effective energy conservation, various techniques are utilized, and stable data supply is crucial for the reliable operation of factories. Many anomaly detection and alert systems for checking the stability of data supply were dependent on Energy Management Systems (EMS), which had limitations. The construction of an EMS involves large-scale systems, making it difficult to implement in small factories with spatial and energy constraints. In this paper, we aim to overcome these challenges by constructing a data collection system and anomaly detection alert system on embedded devices that consume minimal space and power. We explore the possibilities of utilizing anomaly detection alert systems in typical institutions for data collection and study the construction process.

  • Most of the sounds used in animated films are artificially made. A large number of the sounds used are either actual sound recordings or diversely processed artificial sounds made with professional sound equipments such as synthesizers. One animation episode contains numerous amounts of sounds, resulting in significant sound production costs. These sounds have full potential to be reused in different films or animations, but in reality we fail to do so. This thesis discusses ways these sound sources can be acknowledged as added new values to the present market situation as a usable 'digital content'. The iTunes Music Store is an American Apple company product that is acknowledged as the most successful digital content distribution model at the time being. Its system's sound library has potential for application in the Korean sound industry. In result, this system allows the sound creator to connect directly to the online store and become the initiative content supplier. At the same time, the user can receive a needed content easily at a low price. The most important part in the construction of this system is the search engine, which allows users to search for data in short periods of time. The search engine will have to be made in a new manner that takes into consideration the characteristics of the Korean language. This thesis presents a device incorporating the Wiki System to allow users to search and build their own data bases to share with other users. Using this system as a base, the Korean animation sound library will provide development and growth in the sound source industry as a new digital sound content.

  • The main objective of this study lies at examining economic features of IT security investment and comparing alternative mechanisms to achieve optimal provision of IT security resources within a firm. There exists a paucity of economic analysis that provide useful guidelines for making critical decisions regarding the optimal level of provision of IT security and how to share the costs among different users within a firm. As a preliminary study, this study first argues that IT security resources share some unique characteristics of pure public goods, namely nonrivalry of consumption and nonexcludability of benefit. IT security provision problem also suffers from information asymmetry problem with regard to the valuation of an individual user for IT security goods. Then, through an analytical framework, it is shown that the efficient provision condition at the overall firm level is not necessarily satisfied by individual utility maximizing behavior. That is, an individual provision results in a suboptimal solution, especially an underprovision of the IT security good. This problem is mainly due to the nonexcludability property of pure public goods, and is also known as a free-riding problem. The fundamental problem of collective decision-making is to design mechanisms that both induce the revelation of the true information and choose an 'optimal' level of the IT security good within this framework of information asymmetry. This study examines and compares three alternative demand-revealing mechanisms within the IT security resource provision context, namely the Clarke-Groves mechanism, the expected utility maximizing mechanism and the Groves-Ledyard mechanism. The main features of each mechanism are discussed along with its strengths, weaknesses, and different applicability in practice. Finally, the limitations of the study and future research are discussed.

  • We must not consider a culture as means of economy. Specially, it is not possible that is supposed to incorporate a cultural identity in a shape of product, but also international competitiveness can not be raised by it. Because an identify is based on the system of symbol such as language, it can be understood only in a same cultural area. While, the value-in-use of technology can be accepted universally as a formative language of international style. Therefore, the competitiveness of design will say as a special quality that can be acquired in connection with technology. For instance, that Korean mobile telephone could be recognized worldwide is not because it has the Koreanized shape but has a high technology. The public have only a superficial understanding about design. Because that is limited in the visual aspect of product, so called 'the pretty design', which exclude the value-in-use and the organic correlation of form and function in general, it may be a cause of socio-ethical dysfunction. It is providing an elbowroom for making a mistake that can regard the product design as an artistic experiment and try to raise the international competitiveness simply with the visual aspect. And the distorted understanding about design has been diffused rapidly owing to spread of black box products because the over-designed shape is known to the public as a proper result of designing. That reorganize the design category will do as a starting point that can get rid of such a misunderstanding, and do to achieve an ideological role of design for human and society. And it will be a warning to the moral slackening that is due to regarding a style as means of competitiveness and the blindness due to thinking culture as means of economy, and we may expect to offer a basic understanding about design which can prevent products from being visualized.

  • Popular music is a spce where intrinsic desires and values of young people are well exposed in its process of production and consumption. Previous discussions of Korean youth and youth culture have been proceeding mainly in the sense of their resistances to older generation. However, this is limited in that it neglects the inherent microscopic characteristics of youth culture. The purpose of this study is to investigate what the signs and discourses of youth generation make and share in popular music, and how it relates to social context through the 'Mimesis' theory. As a result, the songs of the 1990s remarkably showed the resistance to the old generation in its narrative structure and have signs which expresses repression and uniformity. On the other hand, the songs of the 2010s have many fragmented signs which has been reconstructed into individualized discourse structure. It is assumed that the songs have been able to gain a lot of empathy and popularity from the young generation by visualizing emotions and desires experienced by themselves in the social context. Through this study, it suggests to pay attention to the sensitivity, desire and creativity of young people in music in the social and cultural context of the time.

  • With emergence of Internet, social media, and mobile service, the consumers have actively presented their opinions and sentiment, and then it is spreading out real time as well. The user-generated text data on the Internet and social media is not only the communication text among the users but also the valuable resource to be analyzed for knowing the users' intent and sentiment. In special, economic participants have strongly asked that the social big data and its' analytics supports to recognize and forecast the economic trend in future. In this regard, the governments and the businesses are trying to apply the social big data into making the social and economic solutions. Therefore, this study aims to reveal the capability of social big data analysis for the economic use. The research proposed a social big data analysis model and an online consumer sentiment index. To test the model and index, the researchers developed an economic survey ontology, defined a sentiment dictionary for sentiment analysis, conducted classification and sentiment analysis, and calculated the online consumer sentiment index. In addition, the online consumer sentiment index was compared and validated with the composite consumer survey index of the Bank of Korea.

  • In the modern society, the awareness of images is affecting the body-related consumer behavior through mass media such as TV and internet, and SNS that has grown explosively with the wide availability of smartphones. As a consequence, the demands for aesthetic treatments by patients who wish to improve their inferiority complex are increasing. Patients who want aesthetic treatments display more active inclinations than those receiving general treatments, and have the expectation for the improvement in images along with the anxiety over potential functional problems and satisfaction about the outcomes. In the consultation of the patient of aesthetic case, the basic starting point is that the surgeon and the patient recognize improvement points that the patient expects through the aesthetic treatment. The consultation starting from the viewpoint of the patient proceeds in a way that the consensus is reached through the medical approach, eventually finding the balance between ideals and naturalness. The consultation process from the initial meeting is established at each stage of treatment, at which the consultation is correctly recorded and shared by the surgeon and the care staff. In addition, the consistent policy is implemented from the initial consultation through to the maintenance care. Together, these will result in the consultation based on the true communications leading to the outcome that satisfies the patient, the surgeon and the care staff, rather than the one that gives the patient an unfounded hope and leads to the unsympathetic outcome. This article introduces the consultation strategy for patients of aesthetic case based on the sympathy with them through cases of aesthetic treatment by type.

  • The Korean film has not been on the board of Korean waves due to the limitation of the media accessibility. However, N-screen gives Korean films the chance of being on the board of Korean waves, especially in Asian country which have shared cultural codes. This study aims to demonstrate the possibility of Korean films in asia based on the analysis of Korean film viewers' motivation and media usage. For this purpose the 330 data were collected among Korean, Japanese and Chinese from Feb, 23rd through April, 5th in 2013. The results show the followings; 1) Korean viewers have the strong preference of cinema theater to other media such as PC, VCR/DVD player, tablet PC and mobile phones. Whereas, Japanese viewers prefer VCR or DVD players and Chinese viewers prefer PC and mobile phones. 2) In terms of viewing motivation, social utility is most important to Korean viewers while diversion to Japanese and Chinese viewers.

  • Vehicle platooning through wireless communication and automated driving technology has become realized. Platooning is a technique in which several vehicles travel at regular intervals while maintaining a minimum safety distance. Truck platooning is of keen interest because it contributes to preventing truck crashes and reducing vehicle emissions, in addition to the increase in truck flow capacity. However, it should be noted that interactions between vehicle platoons and adjacent manually-driven vehicles (MV) significantly give an impact on the performance of traffic flow. In particular, when vehicles entering from on-ramp attempt to merge into the mainstream of freeway, proper interactions by adjusting platoon size and inter-platoon spacing are required to maximize traffic performance. This study developed a methodology for establishing operational strategies for truck platoonings on freeway on-ramp areas. Average speed and conflict rate were used as measure of effectiveness (MOE) to evaluate operational efficiency and safety. Microscopic traffic simulation experiments using VISSIM were conducted to evaluate the effectiveness of various platooning scenarios. A decision making process for selecting better platoon operations to satisfy operations and safety requirements was proposed. It was revealed that a platoon operating scenario with 50m inter-platoon spacing and the platoon consisting of 6 vehicles outperformed other scenarios. The proposed methodology would effectively support the realization of novel traffic management concepts in the era of automated driving environments.
