In modern distributed enterprise applications that have multilayered architecture, business entities are a kind of crosscutting concerns running through service components that implements business logic in each layer. When business entities are modified, service components related to them should also be modified so that they can deal with those business entities with new types, even though their functionality remains the same. Our previous paper proposed what we call the DTT (Data Type-Tolerant) component model to efficiently process the variability of business entities, which are data externalized from service components. While the DTT component model, by removing direct coupling between service components and business entities, exempts the need to rewrite service components when business entities are modified, it incurs the burden of implementing data type converters that mediate between them. To solve this problem, this paper proposes a method to use ontology as the metadata of both SCDTs (Self-Contained Data Types) in service components and business entities, and a method to generate data type converter code using the ontology. This ontology-based DTT component model greatly enhances the reusability of service components and the efficiency in processing data variability by allowing the computer to automatically generate data type converters without error.

This paper studied the scheme to realize the manifesto as the method of resolving the side effects after the introduction of the superintendent's election system, a direct election by local residents, in order to implement participative democracy in the educational field. When the superintendent's election system playing an important role in protecting the identity of a state is intruded by the political logic, ideology or factional interest, it leads to the educational crisis such as the damaged independence of the policy and the like. The local educational autonomous system is the institutional arrangement to secure the independence and neutrality of education based on morality and guarantee the democratization and decentralization of educational administration. The scheme to resolve the corrupt aspect of the election of the superintendent is to lead election to the policy-based election. This paper presents the scheme to realize the manifesto movement of the superintendent's electoral campaign to resolve this side effect. All political agents and candidates should be allowed to make free access to diverse information to draw up the manifesto and raise the reliability of the manifesto itself, be guaranteed neutrality, speciality, objectiveness, fairness and the like. In particular, it can be seen that the core task is whether citizens can be involved in the manifesto movement through a shift in their thinking about educational autonomy.

Purpose - Due to highly elevated levels of competition, many companies today have to face the problem of decreasing profits even when their actual sales volume is increasing. This is a common phenomenon that is seen occurring among companies that focus heavily on quantitative growth rather than qualitative growth. These two aspects of growth should be well balanced for a company to create a sustainable business model. For supply chain management (SCM) planners, the optimized, quantified flow of resources used to be of major interest for decades. However, this trend is rapidly changing so that managers can put the appropriate balance between sales volume and sales quality, which can be evaluated from the profit margin. Profit optimization is a methodology for companies to use to achieve solutions focused more on profitability than sales volume. In this study, we attempt to provide executional insight for companies considering implementation of the profit optimization system to enhance their business profitability. Research design, data, and methodology - In this study, we present a comprehensive explanation of the subject of profit optimization, including the fundamental concepts, the most common profit optimization logic algorithm -linear programming -the business functional scope of the profit optimization system, major key success factors for implementing the profit optimization system at a business organization, and weekly level detailed business processes to actively manage effective system performance in achieving the goals of the system. Additionally, for the purpose of providing more realistic and practical information, we carefully investigate a profit optimization system implementation case study project fulfilled for company S. The project duration was about eight months, with four full-time system development consultants deployed for the period. To guarantee the project's success, the organization adopted a proven system implementation methodology, supply chain management (SCM) six-sigma. SCM six-sigma was originally developed by a group of talented consultants within Samsung SDS through focused efforts and investment in synthesizing SCM and six-sigma to improve and innovate their SCM operations across the entire Samsung Organization. Results - Profit optimization can enable a company to create sales and production plans focused on more profitable products and customers, resulting in sustainable growth. In this study, we explain the concept of profit optimization and prerequisites for successful implementation of the system. Furthermore, the efficient way of system security administration, one of the hottest topics today, is also addressed. Conclusion - This case study can benefit numerous companies that are eagerly searching for ways to break-through current profitability levels. We cannot guarantee that the decision to deploy the profit optimization system will bring success, but we can guarantee that with the help of our study, companies trying to implement profit optimization systems can minimize various possible risks across various system implementation phases. The actual system implementation case of the profit optimization project at company S introduced here can provide valuable lessons for both business organizations and research communities.

Management systems for electronic library have been developed on the basis of Client/Server or ASP framework in domestic market for a long time. Therefore, both service provider and user suffer from their high cost and effort in management, maintenance, and repairing of software as well as hardware. Recently in addition, mobile devices like smartphone and tablet PC are frequently used as terminal devices to access computers through the Internet or other networks, sophisticatedly customized or personalized interface for n-screen service became more important issue these days. In this paper, we propose a new scheme of integrated management system for electronic library based on SaaS and Web Standard. We design and implement the proposed scheme applying Electronic Cabinet Guidelines for Web Standard and Universal Code System. Hosted application management style and software on demand style service models based on SaaS are basically applied to develop the management system. Moreover, a newly improved concept of duplication check algorithm in a hierarchical evaluation process is presented and a personalized interface based on web standard is applied to implement the system. Algorithms of duplication check for journal, volume/number, and paper are hierarchically presented with their logic flows. Total framework of our development obeys the standard feature of Electronic Cabinet Guidelines offered by Korea government so that we can accomplish standard of application software, quality improvement of total software, and reusability extension. Scope of our development includes core services of library automation system such as acquisition, list-up, loan-and-return, and their related services. We focus on interoperation compatibility between elementary sub-systems throughout complex network and structural features. Reanalyzing and standardizing each part of the system under the concept on the cloud of service, we construct an integrated development environment for generating, test, operation, and maintenance. Finally, performance analyses are performed about resource usability of server, memory amount used, and response time of server etc. As a result of measurements fulfilled over 5 times at different test points and using different data, the average response time is about 62.9 seconds for 100 clients, which takes about 0.629 seconds per client on the average. We can expect this result makes it possible to operate the system in real-time level proof. Resource usability and memory occupation are also good and moderate comparing to the conventional systems. As total verification tests, we present a simple proof to obey Electronic Cabinet Guidelines and a record of TTA authentication test for topics about SaaS maturity, performance, and application program features.

The public interest and popularity of animation has already forecasted the value of animation as the leader of pop culture and cultural industry. The trend in animation changed from 2D to 3D animation, a new genre that appeared in the 1990s with the development of computer technology and innovative changes in media, and 3D animation secured its position in the 2000s. Researches on 3D animation are conducted in various ways. Integrating the area it shares with film and the area it shares with design, it is produced and consumed. This study focused on 'formativeness(design)', the basis of character design, and tried to find out how it is recognized by the audience, who actually watch and feel it. Also, it approached basic theory and tried to deduce logic that is easy to understand and can analyze design or formativeness which keeps changing. Lastly, this study regards the parts that viewers are not satisfied with as problems, and tries to find out a developmental direction. Among the animations for theaters that were big hits in 2015, this study focused on the characters of and . It reviewed errors and what was lacking in the previous studies, collected experts' opinions and made adjustment. Using the frame prepared through this process, it conducted a survey on study participants, the viewers, to see how it is perceived by them. Finally, it tried to find out the reasons why the audience felt that way through theoretical reviews and applications.

The 'fear' in animation has a couple of problems to apply the criteria for identical genre as in movie or literature. First, the mutilation and destruction of one's body and the appearance of monsters and ghosts are not a normal way of expression and could not apply to one genre. Second, the cause of fear comes from the subject of fear which is a reality that is something 'unrealistic' and 'special' and is approachable. This is all possible in a three dimensional world, but animation is not founded on realism. According to this logic, the horror genre in animation or the esthetic experience of animation is not possible. However, many of the powerful images you can see from the horror genre are all created from animation. Therefore, many writers are drawn to the horror in animation and tried to express in many different ways. This study will include the general idea of fear which drives the audience to the felling of fear and terror but we will mainly focus on the three types of fear - ghost story, cannibalism, and madness - and discover the meaning of fear used in animation. Through this process, we anticipate that fear in animation is not just for pure amusement, but will be able to investigate the meaning of fear philosophically even if the hidden side of reality is terrifying.

This study is to think a new arena of collective play culture at the university campus festival for digital generation used to be individually consuming play in cyberspace. While cyberia is virtual cultural space by providing gigantic platforms in which producers and consumers meet, this space has characterized as individuality and disembodiment, that is why recalling the collective play culture at the off-line. This article is to examine the characteristics and meaning of the recent campus festivals during the history of Korean college festivals, and to analyze proposals of play-contents applied by various theories. The 2016-7' proposals include several kind of board game and experimental theatre sublimed philosophical reflection, which shows a kind of attempt to escape from the cultural industrial logic, however they are characterized by Ilinx(drinking culture) and Alea(board game) emphasized more than Agon, and Mimicry combined with paidia rule strongly. Under the neoliberalism, college students' gloomy reality is represented emasculating of the structure of competitions in the context of an unreal world and Mimicry of experience stay in front of the limen before entering the embodiment.

This paper presents a 10 bit successive approximation register (SAR) analog-to-digital converter (ADC) with a reference driver. The proposed SAR ADC consists of a capacitive digital-to-analog converter (CDAC), a comparator, a SAR logic, and a reference driver which improves the immunity to the power supply noise. The reference driver generates the reference voltages of 0.45 V and 1.35 V for the SAR ADC with an input voltage range of ${\pm}0.9V$. The SAR ADC is implemented using a $0.18-{\mu}m$ CMOS technology with a 1.8-V supply. The proposed SAR ADC including the reference driver almost maintains an input voltage range to be ${\pm}0.9V$ although the variation of supply voltage is +/- 200 mV. It consumes 5.32 mW at a sampling rate of 10 MS/s. The measured ENOB, DNL, and INL of the ADC are 9.11 bit, +0.60/-0.74 LSB, and +0.69/-0.65 LSB, respectively.
