Recently, the cosmetics industry considers male customers as a consumptive, active customer base who also have purchasing power with their stronger desire for their personal image enhancement. Male-preferred image brands have entered the era of unlimited competition through social media, thus increasing the acquisition of male beauty. Therefore, the information for designing favorable image strategies should be examined. This paper examines male awareness, determined by the degree of appearance management based on four categories (i.e., hair and skin care, makeup, foot and hand care, and plastic surgery). Based on the research, the paper proposes a data service to address the spatial and temporal separation problem between TV CF (the major media for recognizing information) and online $caf{\acute{e}}$/blog the major media for obtaining detailed information.

This study is intended to examine the current situation and the problems of the "worksheets, regarding various factors that exert influences onto the quality-risk management, which is one of the most significant factors specifying an apparel product. This paper advances according to the following sequences: 1. Literature survey 2. Field research on actual "apparel vendors" and production factories 3. Investigating the requirements relating to the worksheet 4. Developing standard format of the worksheet 5. Effectiveness analysis on the standard worksheet 6. Proposal of an intelligent model applying standard worksheet system. This study is performed with the following research methods; those are questionnaire surveys, statistical analysis, interviews, collecting & analyzing worksheets, product sample quality experiment, functional analysis of the system, and materialization of the prototype system. The significance of this research is that it suggests the possible effective use of worksheet, which reflects the customers' needs in terms of the product quality, at the stage of the product planning process. Despite its importance, the current work structure does not visibly reflect these components. Therefore, with the result of this research, it is considered that the worksheet systems will meet more useful improvements in risk management process. The limitations of this research are as follows. Although it is evident that the standard worksheets bring effective results in quality improvements of products, considerations must be made onto some additional payoffs arising from the additional cost of necessary labor forces with expert knowledge and cost of the effort and time inputting correct information for running the system.

Interest in companion screen services and high-definition television broadcasting services are rising along with the advanced of digital broadcasting communication technology. Not only providing good-quality broadcasting services in the main screen, but also creating added values of companion services in the secondary screen are important. In this paper we suggest a platform and a related authoring tool generating adaptive companion screen services according to user contexts. The Platform providing adaptive companion screen services based on user environment is designed and implemented for real service market. Proposed platform organizes a higher quality content service considering both user contexts and demands of service providers in real time, and the related authoring tool enables a novice user interface designer and service director to make adaptive user interfaces quickly and easily. We developed and simulated this platform in accordance with Korean UHD IBB standard which provides interactive service applications.

Realistic videos using multi-view videos are created so that the contents shown on multi-view displays or screens look realistic. These images have been mostly used for special videos for exhibition, but, recently, systems such as Screen X have given rise to multi-view images as a format for storytelling contents such as movies. This study used HD-level broadcasting digital video camera with three zoom lenses for shooting wide to close-up shots focusing on a person, in the same way as Screen X, and identified and analyzed problems found during multi-view image registration correction. The results of this study suggested, provided the shooting technique and equipment are improved, the multi-view format can be used for conveying stories and information. Future research will need to investigate and supplement relevant techniques that will enable production of high-quality multi-view image contents by using a cinema-grade camera with standard lenses, instead of using broadcasting-grade zoom lenses.

There are many demands for interoperability between weapon systems as the operational needs for joint and coalition based on network in modern and future warfare have been increasingly needed. In DoD, LISI has been applied throughout information system life cycle from the planning phase to the development phase to assess the level of interoperability. We also developed SITES which is a tool to assess the level of interoperability in information systems. But we should extend the assessment model from the previous information systems to the weapon systems to assess the level of interoperability including weapon systems as well as information systems. In this paper, we proposed the assessment model of interoperability, implemented the E-SITE based on the proposed model, applied 12 weapon systems and analyzed the experimental result.

In order to facilitate the application of BIM technologies in construction projects, a lot of developed countries such as Singapore and the United States are developing a technology development road-map of BIM. In order to develop it, current status of BIM technology in domestic projects must be analyzed in advance. In this study, the element technologies of BIM was identified and the current status and the importance priorities of them were analyzed and evaluated. The result shows that the level of technology developments is behind that of other advanced countries in most of the elements. In technology importance analysis, the BIM based preliminary planning technology and the standards for BIM service contracts are ranked in the high position and their developments are also delayed in Korea. The results of this analysis could show the direction of BIM technology development and also be used for developing the technology roadmap of BIM.

Considering that earlier stage of construction project has a great influence on the possibility of lowering of environmental load, it is important to build and utilize system that can support effective decision making at the initial stage of the project. In this study, we constructed an environmental load estimation model that can be used at the early stage of the project using basic design factors. The model was constructed by using the artificial neural network to estimate environmental load by applying to planning stage (ANN-1), basic design stage (ANN-2). The result of test, shows that average of absolute measuring efficiency and standard deviation of ANN-1 and ANN-2 were 11.19% / 5.30% and 9.59% / 3.09% each. This result indicates that the model using the input variables extended with the project progress has high reliability and it is considered to be effective in decision support at the initial design stage of the project.

Cost Estimate for alternative in design phase of construction become criterion for profitability and feasibility analysis of projects. Initial design phase performed schematic estimate based on similar data in the past. The quantity take-off according to estimators experience and calculation method are occurred different or missing. IT (Information Technology) technology evolution has been promoting BIM technology in construction. It is changing the paradigm of planning, design, construction and maintenance phase throughout the construction project. A number of studies have been attempted to apply BIM technology in the construction. In this paper, we propose schematic estimation framework linking standard format IFC (Industry Foundation Classes) and estimate related knowledge. As a result, it performs a cost prediction for decision-making in the design phase, and expected to overcome the limitations of previous studies. In addition, it is possible actively coping with changes.
