  • In the planning stage of mobile phone development, one of the most important considerations is to select a FormFactor properly to determine the strategy and Purpose of a Product. Up to now, the FormFactor has been selected only by intuitional and qualitative methods. In this study, the Appraisal Methodology using Sensibility Adjectives of Emotion and Sensibility Engineering was presented to suggest the systematic and rational framework in the field of FormFactor selection. First, we verified the conceptual FormFactors with Axiomatic Design and classified the Sensibility Adjectives into the verified FormFactors. When the FormFactor and classified Design Parameters (DP) were given to a designer, the designer implemented the preliminary designs and they were assessed and analyzed by the survey. With these processes, we were able to select the proper designs for FormFactors which were fit for the purpose of a product. This was caused by connecting the Axiomatic Design and tile Sensibility Adjectives. This study gave the possibilities that can be spread to the selection factors, except for the FormFactor, from now on.

  • Cryogenic LNG(Liquefied Natural Gas) which is stored in the cylindrical storage tanks of $100,000m^3$ has very complex flow phenomena and the changes of thermal properties with exterior conditions and operation modes. These complex thermofluid behaviors are affected by the storage, exterior conditions of LNG, design specifications and heat transfer characteristics of tanks. Also, those have influence on the stable storage and supply of LNG in the storage tanks. Thus this study peformed the analysis on the 2-D heat transfer of the tank with exterior conditions, on the Cool Down Process in order to cool down the LNG Storage Tank at the initial normal state, and on the Filling Process considered for incoming and rising of LNG. The analysis on the Mixing LNG Storage was studied too. At last, the visualized program on the complex thermofluidodynamic analysis was developed on the basis of the above analyses. The development of this program becomes to be used to the basic design of the commercial tanks as well as to assure technical skill of the analysis on the thermal stability of the stored LNG in the LNG Storage Tank.

  • The software defects that are not found in the course of a project frequently appear during the conduct of the maintenance procedure after the complete development of the software. As the frequency of surfacing of defects during the maintenance procedure increases, the cost likewise increases, and the quality and customer reliability decreases. The defect rate will go down only if cause analysis and process improvement are constantly performed. This study embodies the defect tracking system (DTS) by considering the Pareto principle: that most defects are repetitions of defects that have previously occurred. Based on the records of previously occurring defects found during the conduct of a maintenance procedure, DTS tracks the causes of the software defects and provides the developer, operator, and maintenance engineer with the basic data for the improvement of the software concerned so that the defect will no longer be manifested or repeated. The basic function of DTS is to analyze the defect type, provide the measurement index for it, and aggregate the program defect type. Doing these will pave the way for the full correction of all the defects of a software as it will enable the defect correction team to check the measured defect type. When DTS was applied in the software configuration management system of the W company, around 65% of all its software defects were corrected.

  • Projection-based augmented reality (AR) system refers to the system that accurately project high quality virtual information at the user-specified area by using the projector. Most of projection-based AR systems use the display device to support high quality and wide screen for increasing the user-immersion. Furthermore, they are implemented on the desktop environment due to the computational complexity. However, these projection-based AR systems are not suited as a mobile system and thus it may be inconvenient in the user point of view. Fortunately, Miniaturization of projectors and improved capacity of the mobile processor allowed the mobile AR system to be convenient. The limitation of established mobile AR system is that it uses small display screen which does not support high-resolutions and thus it may reduce the user-immersion into the system. In this paper, we propose portable projection-based display system, which overcomes the limitations of both projection-based and mobile-based AR systems. We have conducted the user evaluation to verify the effectiveness and the utmost capacity of the system.

  • Outsourcing enables firms to use external resources in efficient and effective manner by adopting the best practice of industry. It also helps firms improve their business process which may result in seizing or creating new business opportunity. Collaborating with outstanding BPO(business process outsourcing) providers offer a great deal of advantage that could access to new knowledge, technology, intellectual and material resources that firms do not own. This study was designed to provide in-dept understanding of key elements that may affect the attitude towards BPO of entrepreneurs using 99 samples comprised SME & Venture business owners. Specifically, this study aims to test and analyse the relationship between attitude towards BPO and 4 independent variables including cost reduction, core competence, specialized resources and quality improvement. The analysis results show that core competence, specialized resources and quality improvements have all positive relationships with the attitude towards BPO. However, exceptionally cost reduction is not associated positively with the attitude towards BPO which was against our expectation. Theoretical discussion and practical implication on the analysis results are provided.

  • The recovery of Zr from Zircaloy-4 (Zry-4) cladding hulls using a chlorination method was demonstrated for complete conversion of Zr into $ZrCl_4$. A chlorination reaction was performed by reacting Zry-4 hulls for 8 h under a 70 cc/min $Cl_2$ + 70 cc/min Ar flow at $380^{\circ}C$. The initial weight of the reactant (51.7 g) decreased to 0.49 g after 8 h of operation, which is only 0.95wt% of the initial weight. The weight of the total reaction products was 121.7 g with a high Zr purity of 99.80wt%. Fe and Sn were identified as major (0.18wt%) and minor (0.02wt%) impurities of the reaction products, respectively. It was also shown that Zr exhibited a high recovery ratio of 96.95wt% with a relatively small experimental loss of 2.34wt%. Observation of the reaction residues revealed that the chlorination reaction was dominant along the longitudinal direction, and surface oxide layers remained as reaction residues. The high purity and recovery ratio of Zr proposed the feasibility of the chlorination technique as an effective hull waste treatment method.

  • The purpose of this study is to discover the plans for Yangyeongsi in Daegu, one of the most traditional streets and a tourist spot in South Korea, by preserving the historical place, reviving the historical characteristics and identity, revitalizing the uniqueness of the location, and developing the environment. This paper also illustrates the problems of the place through a investigation into its current state in order to promote the district and conduct a fundamental research framework to suggest future development methods and directions based on the problem statements. Daegu Yangyeongsi was chosen through frequency analysis and a survey asking for a suitable location and local characteristics to be developed for the local promotion through the field investigation of 158 cultural assets registered in the local government. This survey was conducted through the development process of the Regional Design Innovation Center to revitalize the traditional streets and places of interest. Through this investigation, 19 sites and traditional streets, which can be cultural resources for sightseeing and contribute to the local promotion, were extracted. Yangyeongsi, was selected from the finalists. The research methodology will be 1) to identify things for improvement potentiality through an in-depth analysis of Yangyeongsi, 2)to examine the mutual relationship between the revitalization strategy of Yangyeongsi and the city promotion strategy, and 3) to integrate the problems and improvements based on the results of the analysis. The notion of SWOT analysis synthetically considering the elements of opportunity and intimidation, strength and weakness to come up with the development direction was introduced to discover the local characteristics of Yangyeongsi and deduce the problem statement through the state analysis. Based on these results, the future development method and direction will be suggested in this paper through the revitalization study of Yangyeongsi.

  • This study explores the IT governance structures of the Korean conglomerates. It investigates IT organization structures, decision making frameworks and processes, communication channels, implementation mechanisms, and performance evaluation methods around IT activities of the Korean conglomerates by analyzing four different cases. The results show that all of the conglomerates have an IT service firms as one of their subsidiaries, and all the subsidiaries in the conglomerates outsource their IT divisions to the IT service firms, The client firms in the conglomerates operate IT strategy and planning teams to coordinate their IT activities with their outsourcing partners. The IT governance archetype of the Korean conglomerates is found to be "business monarchy" because the client firms mostly make IT decisions. However, the IT service firms provide the information of IT trends and solutions to their clients, so the IT governance archetype of input framework for IT decisions can be "IT monarchy". In addition, the conglomerate which has the more centralized IT governance architecture appears to prefer the more integrated implementation mechanisms for IT decisions. The results of this study are expected to be used as a benchmarking model for the organizations which try to develop an effective IT governance structure.
