As a new management paradigm, co-creation for creating new value through collaboration with stakeholders, including customers, distributers, suppliers, and partner organizations has been issued in the private and public organizations. To collectively create new value, effective communication tools among the interest groups should be provided. In fact, most of organizations have utilized information technology such as home pages and SNS for distributing information and respecting customer opinions. However, they are seriously experiencing in difficulty of systematic management and overlapped investment on information technology for co-creation. Thus, this study proposes the conceptual model for co-creation platform through case studies and it is verified by scenario analysis and experts. The study contributes to accumulate knowledge in the area of co-creation platform. It also defines the requirements and the functions for the design of co-creation platform for practitioners.

In order to understand the flow properties of the South Sea of Korea, tidal currents, wind-driven currents, density-driven currents and residual flows were investigated by using 3-dimensional numerical model(POM). In offshore regions, tide-induced residual current tends to flow eastward during the spring tide and westward during the neap tide. Total residual flow is irregular due to the bottom topography in the coastal area. The density-driven currents in the coastal area showed to be relatively weak, with little seasonal differences. The special tendency was apparent in the open sea. That is, the flow in the offshore regions showed results similar to that of the Tsushima current. The wind-driven currents in the coastal area showed to be much stronger than in offshore regions. Vertically, the flow of the surface layer was much stronger than that of the bottom layer. Through these results, material transport and diffusion in the south coast, as a basis for predicting the spread of use is expected to be available.

A judgment on the redevelopment projects' predicted profitability is an essential decision-making element for the success of the redevelopment projects. It is necessary to review the literature on profitability of redevelopment project and draw risk factors that could affect profitability through the risk analysis based on surveys. It is also necessary to judge profitability prediction toward the business value of the redevelopment project in the planning phase according to the risk analysis results which can affect the profitability prediction. In order to prevent the growing difficulties in executing the projects, a profitability prediction model is proposed using the method of management and disposal based on a proportional calculation that can estimate the share of expenses in order to judge profitability in the planning phase. With the improvement of profitability prediction models, it is possible to appropriately judge profitability in the planning phase in order to allow the prevention of suspension, reduction of project term, reduction of cost, and making of rational decisions.

The game industry has been seeing rapid change brought on by the competitive environment globally. As a result, game design skill is being magnified as a key to success. Because of lack of game design skills, Korean game market is in crisis recently. The game analysis is necessary to enhance game design skills. However, criteria and definition of game analysis is not clear and it is difficult to use for game development. This paper will suggest H-G model which has two factors that are 'human role' and 'the scope of game analysis'. This model segments 9 types of game analysis method. This study finds the limitation of leading researches and tries to improve it mapping the major leading researches to H-G model. This paper would help to make the game analysis be integrated and systemic research as regards 9 types of H-G model.

Torsional vibrations, such as the gear rattle of the manual transmission in vehicle systems, are correlated with the firing stroke from the engine. These vibro-impacts can be examined based upon linear time-invariant analysis. In order to understand the gear dynamics, a specific manual transmission with a front-engine front-wheel drive configuration is investigated. A method to reduce the degrees of freedom is suggested based upon the eigensolutions and frequency response functions, which will lead to the development of an efficient matrix size. The dynamic characteristics of single- and dual-mass flywheels are then compared. The effect of the dual-mass flywheel is investigated based upon the mobility analysis, which will lead to understanding of the concepts for avoiding vibro-impacts. A linear time-invariant system model is examined by employing the effective clutch stiffness from a two-stage clutch damper. Thus, the relationship between the dynamic characteristics and the clutch damper can be predicted by assuming a combination of different stage stiffness levels.

The purpose of this study is (1) to present a model for Capstone design class in English education, and (2) to recognize students' performance and perceptions about Capstone design class in English education. The participants were senior students majoring in English education. The Capstone design class model was developed, applied, and evaluated after changing 'English-American Culture' subject to 'Capstone Design for English-American Culture Education.' In this study, the class design, performance procedures, derived topics, and examples of performance outcomes were presented. The classes were also evaluated through an understanding evaluation of English-American culture, task performance and final outcome evaluation, a descriptive satisfaction assessment of students, a lecture evaluation, and a teacher's self-reflection assessment. As the result, the average score of a class that applies Capstone design was higher than that of a class that does not apply the Capstone design. There were many positive opinions regarding the Capstone design class. In addition, the teacher's self-reflection indicated that students should be exposed to such design from the beginning.

Library of Congress introduced BIBFRAME as a new bibliographic framework to enhance web accessibility of bibliographic records and their integration to Web of data. This study introduces BIBFRAME model and its current status, reviews BIBFRAME classes and properties, and presents a mapping between MARC21 and BIBFRAME. The study aims to help the understanding the deployment of BIBFRAME in bibliographic description. BIBFRAME categorizes bibliographic entities into Work-Instance, and employs RDF/XML and URIs to identify resources and specify semantics of the resources on the Web. It also suggests an Annotation entity to provide additional information produced by users and external organizations. BIBFRAME is significant in that it presents a new paradigm of bibliographic description and expands users' information discovery in the context of Linked Data. Continuous researches are required to support its content model agnostic application to diverse resource type, which may entail a modification of BIBFRAME model and vocabulary. It also calls for guidelines for using the complicated vocabulary in a coherent way.

태양과 같은 별의 형성기작은 질량이 큰 별의 형성기작에 비해 비교적 잘 연구되어 왔다고는 하지만, 이 또한 온전한 이해와는 거리가 먼 상황이며 여전히 논란의 대상이다. IRAS, Spitzer와 같은 적외선우주망원경으로 얻어진 원시성의 광도함수는 일반적으로 받아들여졌던 별탄생 이론으로 설명되지 못한다는 것이 밝혀졌고, 이에 새로운 별탄생 이론이 필요하게 되었다. 새롭게 받아들여지고 있는 별탄생 모델은 Episodic Accretion 모델로서, 원시행성계원반에서 원시성으로 질량 강착이 간헐적이면서 폭발적으로 일어난다는 것이다. 이러한 모델의 관측적 증거의 하나는 FU Orionis와 같은 천체로서, T-Tauri 단계에 있는 원시성이 본래의 밝기보다 약 100배, 즉 가시광에서 5등급 이상 폭발적으로 밝아진 천체이다. 질량강착의 과정은 행성형성의 초기조건을 결정하는 원시행성계원반의 물리적, 화학적 특성을 결정하므로, 그 이해가 중요하다. 따라서 본 연구팀은 Episodic Accretion이 원시행성계원반과 원시항성풍의 형성과 진화에 어떤 역할을 하는지 연구하기 위하여, 보현산 천문대의 고분산 분광기인 BOES를 이용하여, 최근에 폭발을 일으킨 원시성인 HBC 722와 2MASS J06593158-0405277을 모니터링 관측을 해왔으며, 이전에 알려진 6개의 FU Orionis 형 천체들도 관측하였다. 여기서는 그 결과를 발표하고자 한다.

In order for a financial company to collect personal information, it explicitly notifies consumers of the contents stipulated by law and gets consent beforehand. As a result, as financial products became more complicated and diverse, and the contents of 'Consent form for providing personal information' became more complicated and more. In particular, in the case of internet or mobile, the letter became smaller as the screen size limit, making it more difficult to understand. This is because almost all companies that collecting personal information are in a similar situation, In the position of consumers who use services are, contradictions arise that habitually agree without understanding the consent contents. In this research, in order to present a consent policy establishment decision-making model to rationally collect and use personal information through the Internet website of financial companies, consider the domestic and foreign legal system Then, derive a problem To present improvement measures. In addition, the evaluation factors selected through the research are verified by presenting decision making models and formulas using AHP (Analytic Hierarchy Process) method.
