In this study, the effective technology readiness assessment (TRA) method for system development project is suggested. We analyze the domestic and foreign TRA practice and derive the new idea to resolve the problems found from the analysis. Domestic and foreign organizations develop and use checklist for the precise TRA, but the checklist has some problems in type of questions and analysis of assessment. TRA method using the original TRL definition or the checklist should be selected depending on the project characteristic. Questions of the checklist should be classified into critical or non-critical according to their importance. Finally, Test and evaluation master plan (TEMP) in system engineering process can provide an obvious criteria to assess technology readiness level (TRL) of critical technology elements (CTE) composing the system.

Information Technology (IT) has been working as an engine of growth in Korea since early 1990's. For the next leap of Korean economy and to overcome worldwide financial crisis, Korea's IT industry needs to find a new breakthrough. In this viewpoint, we tried to empirically analyze the impact of Korea's IT trade on domestic industry. Since Korean government is trying to set up a few free trade agreements (FTA) with major trade partners, more accurate understanding of the impact of FTA is required to find the correct way to promote Korea's IT industry. We first looked at the current status of Korea's IT trade with major partners such as the US, Japan, and China to understand the competitiveness of Korea's IT industry. Having done this, we measured the impact of IT trade on domestic industry using Granger causality test. The results showed that the positive impact of trade is bigger on IT industry than on whole industry. Also, the impact of import turned out to be bigger than that of export. Among the major trade partner countries, the US’s and China's impacts are bigger than Japan's impact. Another notable thing is that IT product import from the US has especially big impact on domestic IT industry. Our findings may have certain implications to the FTA related policy.

Throughout the twentieth century, American furniture was subject to a number of influences-both domestic and foreign. Especially, in the first half of the twentieth century, there were strong foreign influences compare to the later half of the century. Therefore, this study aimed for discussing foreign influences and for addressing issues such as attitudes toward materials, ornamentation, and technology. As a result, this study suggests how American furniture becomes instinctive moving away from strong foreign influences from the second half of the century. The twentieth century was a period of rapid and dynamic change for American furniture design. In many ways, the designs throughout the century were reflective of the social, political, and economic culture of the time. With the birth of the modern movement in Europe and a strong influx of foreign immigrants, American design in the first half of the century was characterized by a reliance on European and foreign influences. However, after the two world wars, strong domestic influences came into play. The two world wars provided the essential catalysts for change: new materials, developing technology, and changes in life style and consumer values. A historical examination of design trends and individual designers illustrates how American furniture design evolved during this period.

In the construction industry, adoption of BIM is a global tendency whereas it doesn't seem to be fully activated in domestic market. Thus, the need of BIM ROI measurement is emerging. There has been a few researches which is only focused on evaluating achievement of BIM in constructional stage. However, it's hard to find any studies on the case of measurement of BIM ROI at the design phase. Therefore, this paper analyzes the domestic and external 12 advanced researches in the measurement of BIM ROI and suggests common investment and return facts. Based on this, this paper proposes a measuring method which is applicable in domestic architectural firms. To determine the appropriateness of the measure, there has been an expert survey and interview. According to the expert survey, the measure itself is practical. But in other survey targeting industry employee, actual profit and efficiency appear to be significantly different from previous expectations. In short, in the domestic conditions in the design stage, the introduction of BIM doesn't have a practical effect and this is one of the main reason why BIM can't be fully functional.

The purpose of this study was to investigate current QR technology usages and merchandisers' roles and information activities in the Korean apparel industry. Data were collected by interview and questionnaire with merchandisers in apparel companies, manufacturing apparels for both men and women. Statistical analyses were t-test, ANOVA, frequency with SAS program. The results of the study were as follows: 1. The usage of QR technology was generally low. But POS, bar-coding, logistics and small lot order were highly used compared to other technologies. CAD, automated sewing operation, unit product system, logistics, and small lot order were more used in domestic national brand than in import license brand. POS applications were more used in product planning division than in others. 2. Merchandisers played important roles in making major decisions on cost price, sales price, manufacturing request, delivery data, production quantity, produce mix, budget planning, market timing and delivery channels. Products planning was conducted mostly on a monthly basis. Price was determined mainly according to cost price, while the production quantity depended on the last year's sales. Usually sales were analyzed on a daily basis. 3. Merchandisers got more information on fashion them and color trend from foreign information sources than from domestic, while more information on fabrication from domestic sources. For fashion design information they used the equal amount from domestic and foreign sources. Over all degree of utilization in each field of fashion information was fugured rather high.
