1990년대 초 이후 탈냉전 시기에 들어서면서 다양한 안보위험 요소가 등장함에 따라 국가안보의 개념이 전통적인 군사력 위주에서 경제력으로 옮겨 갔다. 국가안보 개념의 변화로 각국은 국가이익 확보를 위하여 외국에 대한 경제정보 산업정보활동에 주력하게 되면서, 이에 대응하기 위한 산업기술보호 활동도 국가안보차원에서 수행하게 되었다. 미국 등 주요 선진국들은 "경제스파이처벌법"등을 제정 시행하는 등 자국의 첨단산업 기밀을 보호하기 위하여 강력한 보호 정책을 추진하고 있다. 우리나라는 IT, 조선, 철강, 자동차 등의 분야에서 세계적 수준에 도달하였고 매년 막대한 자금을 첨단기술의 및 개발에 투자하고 있으나 지금까지 체계적인 산업보안활동이 전개되지 못한 실정이다. 하지만 이러한 산업보안은 특성상 공적인 사법기관의 독자적인으로는 수사를 하는데 많은 어려움을 겪는 것이 사실이다. 따라서 민간조사원이 은밀하게 기업사건에 개입하여 증거를 수집하고 정보를 입수하여 위험성을 사전에 확인하고 조치 예방하는 것이 효과적일 것이다. 신속하게 처리해야 하는 범죄를 조사하는데 효과적인 민간조사제도를 국가의 공적인 사법기관이 개입하기 곤란한 산업스파이와 같은 기업범죄 등에 활용함으로서 기업 뿐만 아니라 국가, 나아가 국민의 경제의 손실을 예방할 수 있는 제도가 될 수 있을 것이다. 여기서는 이러한 점을 인식하고 민간조사원(탐정)을 활용한 산업 스파이 대응방안을 제시하고자 한다.

Using the gravity model, this paper analyzes empirically how the world trade in goods is affected by regional trade agreements(RTAs) which have been spreading rapidly since the mid-1990s. This paper attempt to do the panel data analysis about 174 countries during the period of 1994-2008. These panel data include 157 RTAs. It is meaningful that this paper uses comprehensive data to analyze the net effect of regional trade agreements on the global trade volume. This provides a clue as to the answer to the stumbling block debate raised early in the regional trade agreement. Also, confirming how the participation of the WTO affected the trade volume among the member countries, the WTO-related dummy variables are additionally introduced to this gravity model. And as far as we know, the state system-related variables is first considered in this model. This variable reflects the social and cultural environments of countries as the proxy variable representing the sociocultural homogeneity. In all regressions, joining to the WTO and consistency of the state system have a positive effect on increasing the trade volumes between countries. According to the analysis of RTA trade effects, RTAs, on average, increase the volume of trade within the RTA region by 27%~37%, and decrease the volume of trade between the regional and the non-regional nation by 1.2%~3.4%.Therefore, the net effect of regional trade agreements on the promotion of global welfare is positive. For robustness check, we also introduce the interaction term of the dummy variable which reflects the RTA tightening and the continuous variable which reflects the distance effect. As a result, the RTAs alleviate the trade-decreasing effect which is caused by the distance between the countries.

본 논문은 다양한 서비스 클래스가 제공되는 BcN (Broadband convergence Network) 환경에서 상위 우선순위 서비스의 품질을 보장하기 위한 능동 큐 관리 메커니즘 (Active-WRED)을 제안한다. 네트워크 혼잡 상황에서 제안된 메커니즘은 상대적으로 낮은 우선순위를 갖는 서비스의 drop 확률을 증가시키고 이에 따라 상위 우선순위 서비스의 drop 확률을 감소시킴으로써 상위 우선순위 서비스에 대해 패킷 손실로부터 품질을 보장할 수 있다. 제안된 능동 큐 관리 메커니즘의 성능을 분석하기 위해 이산 시간 큐잉 시스템의 통계적 분석 방법을 도입하였다. 두 서비스 클래스 (GS: Guaranteed Service, BS: Best Effort Service)만을 고려하여 제안 방안의 성능 분석을 위해 MMBP-2 (two-state Markov-Modulated Bernoulli arrival Process) 트래픽 소스 모델과 2차 이산시간 Markov 체인을 도입하였다.

이 글의 목적은 19세기이래 스페인의 국가발전과 관련하여 지역주의가 어떻게 전개되어 왔는가를 살펴보는데 있다. 지난 2세기 동안 스페인의 지역주의는 국가발전에 적잖은 영향을 미쳤다. 한편으로 강력한 지역주의의 재흉은 스페인의 국민형성에 구조적 취약점으로 작용하였을 뿐 아니라, 바스크, 카탈루냐, 갈리시아 등 주변부의 영역적 민족주의 운동이 성립하는데 중요한 계기가 되었다. 하지만 다른 한편으로 지역주의는 지역담론과 문화적 접근을 통하여 국가의식을 강화하는데 기여하였다. 따라서 지역주의에 관한 통념과 달리, 스페인의 지역주의는 국민국가의 형성에 대립하면서도 동시에 보완하는 독특한 성격을 보여주었다. 지역주의의 오랜 역사적 발전과정은 프랑코체제를 거쳐 1970년대 후반 민주적 전환기에 지역분권화를 바탕으로 한 국가체제의 형성으로 귀착되었다.

In this study, we first measured the malmquist productivity index by DEA among the Korean public firms. Second, there are 12 public corporations whose productivity (MPI) has decreased compared to 2014. This is mainly because of a decrease in productivity, as well as a decrease in the technical efficiency change index (TECI), impacted by the internal environment, and the increase in productivity because of an increase in the technology change index (TCI) impacted by the external environment. Finally, the analysis of the impact on the management assessment scores showed that the productivity (MPI), scale efficiency (CRS), size of sales, operating profitability, and total capital investment efficiency are significantly related (+), except for the asset turnover, which is a static financial ratio. Meanwhile, the management evaluation scores between the high-productivity public corporations and low-performing public corporations were significantly discriminating. Thus, it is confirmed that the nation's state-run companies must manage their MPIs in a time series to score high in management evaluation.

The purpose of this study was to examine the effect of social support on type 2 diabetes by classifying it into diabetes and impaired fasting blood sugar, a pre-diabetic state. Subjects of this study were 22,846 adults aged 30 years or above who agreed and registered to participate in the "Korean Health Examine Cohort (KOEX)" study that simultaneously collects questionnaires and biological samples at 8 university hospitals around the nation. Normal fasting blood sugar was defined as below 100 mg/dL, and impaired fasting blood sugar was defined as 100~125 mg/dL. Diagnosis of diabetes was defined as fasting blood sugar of 126 mg/dL or above, diagnosis by a doctor, or medication of insulin or oral hypoglycemic agent. Social support groups were divided into 4 groups, and Group 1 (G1) had high positive support and low negative support. This is the reference group with the highest social support. During multivariate analysis, female group (G3) that had high positive support and high negative support showed prevalence of impaired fasting blood sugar 1.19 times higher (95% CI = 1.02~1.41) than G1. As this study confirmed that social support increases fasting blood sugar of women after correction for socioeconomic status, health behavior, and biological and medical variables, it implies the importance of social relations such as social support in addition to management of personal risk factors for prevention of type 2 diabetes.

In the most of a nation, the safety and emission gas inspection system of a vehicle in service have been conducted with the most compatible inspection system according to its real environmental situation. Especially, the state of vehicle emission gas is measured by advanced emission gas inspection equipment. It has the problem that the decrease effect of an environmental pollution matter is not calculated by weight percent measurement type equipment. Therefore, in this study, the correlations for the results of emission gas measurement are analyzed by comparing a weight percent measurement type (IDLE+ASM2525 mode) and an advanced mass measurement type (IM240 mode). As the result, the selectivity of an emission gas by IM240 mode is higher than that by IDLE+ASM2525 mode. In the future, therefore, the introduction of IM240 mode and a mass measurement type equipment are necessary. Also, we need to prepare a vehicle emission gas inspection system for introducing IM240 mode.
