  • 미국이 대 이라크전 연장선에서 북한 핵문제를 봄에 따라, 한반도의 긴장은 날로 증가하고 있으나, 국내 여건의 변화에 따른 국방 가용재원의 감소, 대규모 야외군사훈련을 수행하기 위한 공간확보의 어려움 및 안전과 환경문제 등으로 인해 한국군의 야외훈련 여건은 날로 열악해져 가고있는 실정이다. 이에 따라, 야외훈련의 대체방안으로서 보다 경제적이고 과학적인 워게임 모델에 의한 CPX(Command Post Exercise: 지휘소연습) 즉, 워게임 연습이 최적의 대안으로 주목받고 있으며, 이를 통한 단독, 합동 및 연합연습이 수행되고 있다. 그러나, 현 워게임 연습체계는 정보보호라는 관점에서 볼 때 많은 문제점을 안고 있다. 국방전용망의 경우 그 구성이 인터넷과의 단절을 전제로 네트워크 레벨에서의 암호화만을 통해 데이터를 보호하고 있는 실정이고, 워게임 연습체계 내에서의 공격이나 신뢰하고 있는 네트워크를 통한 공격에 대해선 무방비 상태에 놓여져 있으며, 시스템 레벨에서의 보안 또한 부실한 실정에 있다. 따라서, 본 연구에서는 워게임 연습체계의 효율적이며 안전한 정보보호 방안 제시를 위해 네트워크 레벨에서의 정보보호 체계 및 시스템 관점에 초점을 두고 연구가 수행되었으며, 결론적으로 현 워게임 연습체계에서의 최적의 정보보호 방안을 제시하고자 한다.

  • Art Furniture is a terminology of creative and developed activity related Art in the field of furniture design. In a broad sense, the extent of Art furniture reaches from humanities to technology because Art includes them. Due to Postmodernism, designers who were involving Art furniture started to fuse various studies including high technology to achieve their own goals. To illustrate with the characteristic of high technology, I compare between low technology and high technology. Even though high technology are used both commercial furniture and Art furniture, the latter has been utilized high technology in a more creative and experimental way to develop experimental furniture design. In contrast, in order to earn economic profit, there is no unnecessary risk for commercial furniture. Considering information revolution which is deeply related with high technology, Art furniture designers could get information easily about other fields and make multiple connections of different kinds of people and markets. As a result, a combination between Art furniture and high technology has distinctive features. At first, high technology was applied to craft among Dutch furniture designers. After that, designers began to lay out the method of high technology and pushed the boundary of Art furniture thanks to experts and scientists. In addition, there was a designer who have conducted a series of research as a scientist adopting scientific methodology. In doing so, Joris Laarman could obtain a revolutionized work which could contribute society. In conclusion, combining Art furniture and high technology leads the definition of design from deciding physical shapes to directing and organizing processes.

  • Purpose - Food consumption in Korea has changed in paradigm as it has grown qualitatively in the past in quantitative shortages. Consumer food consumption patterns are rapidly changing due to changes in economic, social and population conditions, scientific and technological development, climate change, and market opening. At the same time, there is a need to actively respond to these changes in terms of the food industry, market, and government policy. The purpose of this study is to examine the changes and characteristics of food consumption expenditure of Korean consumers in-depth and depth in order to provide implications for agriculture, food market and policymakers. Research design, data, and methodology - We analyzed various food consumption changes from the 1980s to 2015 through Household Income and Expenditure Survey raw data from MDIS(Microdata Integrated Service) of Statistics Korea. and conducted the age effect, generation effect, and year effect by cohort analysis. We also conducted comparisons with OECD countries on several indicators. Results - Food consumption spending was slow, and there was no significant change in home consumption, while eating out consumption increased about 20 times in 2015 compared to 1980. Income, age, residential area, number of household members showed significant changes in food consumption. According to the cohort analysis, the changes in the food consumption structure are largely due to age effect, and the year, age, and generation effects are different for each food item. Conclusions - Food consumption has a significant impact on not only the nutritional status of consumers but ultimately the public health. Therefore, they should be regarded as a strategic policy area of central government rather than a matter of size and change of food consumption expenditure.

  • Purpose - purpose of this paper is to analyze the effects of the investment facilitation levels of 11 RCEP countries (excluding Myanmar, Brunei, and Laos due to lack of data) on China's outward foreign direct investments(OFDI) using balanced panel data from 2010 to 2019. Design/methodology - First, four investment facilitation measurement indicators (regulatory environment, infrastructure, financial market, ease of doing business) were selected,investment facilitation scores of the 11 countries were obtained using the principal component analysis, an investment gravity model was established with nine explanatory variables (investment facilitation level, market size, population, geographic distance, degree of opening, tax level, natural resources, whether the country is an APEC member or not, and whether a valid bilateral investment treaty with China has been concluded) were used to establish an investment gravity model, and regression analyses were conducted with OLS and system GMM. Findings - The results of the regression analyses showed that investment facilitation levels had the greatest effect on China's OFDI, all four first-level indicators had positive effects on China's OFDI, and among them, the institutional environment had the greatest effect. In addition, it was shown that explanatory variables such as market size, population, geographical distance, degree of openness, natural resources, and whether or not a valid bilateral investment treaty has been concluded would have positive effects on China's OFDI, while tax levels and APEC membership would impede China's OFDI to some extent. Originality/value - Since the Regional Comprehensive Economic Partnership (RCEPT) came into effect not long ago, there are not so many studies on the effects of investment facilitation levels of RCEP member states on China's OFDI, and the investment facilitation measurement index constructed in this paper is relatively systematic and scientific because it includes all the contents of investment facilitation related to the life cycle of company's foreign direct investments.

  • Six Sigma is a philosophy and systematic methodology for quality improvement. It encourages continuous quality improvement efforts to achieve the ideal goal of 6σ. Sigma(σ) is a statistic representing the standard deviation of the normal distribution, and 6σ level means a level where the tolerance of the specification is six times the standard deviation of the process distribution. In terms of the defective rate, the 6σ level achieves the 0.002 defectives per one million units. However, in the field, the 6σ level is used in the sense of achieving 3.4 defects per one million opportunities, which shows a large gap from the 6σ level in the statistical viewpoint. This is because field practitioners accept a 1.5σ shift of the mean of process when calculating the defective rate under sigma level. It said that the acceptance of 1.5σ shift of the mean is from experience, but there is no research or theoretical explanation to support it logically. Although it is a non-scientific explanation based on experience, considering that there has been no objection to the 1.5σ shift for a long time and it is rather accepted, it is judged that there is a reasonable basis for the 1.5σ shift. Therefore, this study tries to find a reasonable explanation through detective power of control chart via the run-rules to the 1.5σ shift empirically recognized by practitioners.
