새로운 UN해양법 협약의 발효로 연안국 관할권이 확대됨에 따라 해양은 자유 이용의 시대에서 분할 관리의 시대로 전환되고 있다. 이와 동시에 우리나라의 수산업은 한ㆍ일, 한ㆍ중 어업협정의 체결로 인한 어장 축소, WTO체제에 따른 수산물 시장의 전면 개방, 자원관리형 어업을 위한 조업 규제의 강화, 해양환경 오염에 따른 수산 자원의 감소 등으로 큰 어려움에 직면해 있다. 전통적인 선박에 의한 광역의 어해황정보 수집 및 광역어장의 정확한 조업위치 파악은 한계가 있다. (중략)

1994년 UN해양법이 발효된 이후, 새로운 해양질서시대를 맞이하여 우리나라의 수산업, 특히 어선어업은 한ㆍ일 어업협정, 한ㆍ중 어업협정으로 인한 어장축소, WTO체제에 따른 수산물 시장의 전면개방, 자친관리형 어업을 위한 조업규제의 강화, 해양환경오염에 따른 수산자원의 감소 등으로 큰 어려움에 직면해 있다. 그리고 TAC제도 도입 등으로 어획실적의 확보 및 그 자료 관리의 중요성이 절실히 요구되고 있는 실정이다. (중략)

암호의 이용은 개방 네트워크상에서 보다 안전한 통신을 보장한다. 그러나 암호 이용이 이러한 긍정적 측면만 있는 것이 아니다. 암호용 비밀키를 유실했을 경우, 데이터를 복구할 수 없다. 또한 암호가 범법자에게 이용될 경우, 정부는 법 집행능력을 확보할 수 없게 된다. 이러한 문제점들을 해결할 수 있는 방법이 키 복구이고 여러 선진국들에 의해 많은 연구가 진행되고 있다. 본 논문에서는 키 복구의 기술적 동향을 파악하기 위해 실질적으로 개발되어 이용 중인 키 복구 기능이 포항된 제품들의 특징과 활용분야를 분석하고 이들을 비교하였다.

우리 주변에는 수학영재 교육 대상자로 선발되어 영재교육을 받지 않는 학생 중에는 수학적으로 유망한 학생들이 많이 있으며, 이들에게 적절한 프로그램을 제공한다면 수학적 재능을 발휘할 수 있을 것이다. 본고에서는 수학적으로 유망성이 있는 학생들을 위한 프로그램 구성 및 운영 모델의 하나로 개방형 접근법(Open-approach heuristic)모델에 따른 구체적인 지도 방안과 프로그램에 대해서 살펴보고자 한다.

The normalized difference in incident solar energy between a target surface and a level surface (overheating index, OHI) is useful in eliminating estimation error of site-specific maximum temperature in complex terrain. Due to the complexity in its calculation, however, an empirical proxy variable called northern exposure index (NEI) which combines slope and aspect has been used to estimate OHI based on empirical relationships between the two. An experiment with real-world landscape and temperature data was carried out to evaluate performance of the NEI - derived OHI (N-OHI) in reduction of spatial interpolation error for daily maximum temperature compared with that by the original OHI. We collected daily maximum temperature data from 7 sites in a mountainous watershed with a $149 km^2$ area and a 795m elevation range ($651{\sim}1,445m$) in Pyongchang, Kangwon province. Northern exposure index was calculated for the entire 166,050 grid cells constituting the watershed based on a 30-m digital elevation model. Daily OHI was calculated for the same watershed ana regressed to the variation of NEI. The regression equations were used to estimate N-OHI for 15th of each month. Deviations in daily maximum temperature at 7 sites from those measured at the nearby synoptic station were calculated from June 2006 to February 2007 and regressed to the N-OHI. The same procedure was repeated with the original OHI values. The ratio sum of square errors contributable by the N-OHI were 0.46 (winter), 0.24 (fall), and 0.01 (summer), while those by the original OHI were 0.52, 0.37 and 0.15, respectively.

This study seeks to clarify the mechanisms of anthropomorphism and positive user experience. This study adopts the "computers are social actors" (CASA) paradigm to verify the causal relationship between social response and anthropomorphism and correctly explicate this paradigm. The intimacy-forming and anthropomorphizing effects of deep self-disclosure in interpersonal relationships were replicated in relationships between humans and conversational agents to induce both social response and anthropomorphism. Then, the mediating effect of intimacy on the anthropomorphizing effect of deep self-disclosure was explored with psychological models that revealed the causal relationships between social connections, including intimacy and anthropomorphism. Furthermore, we explored how intimacy and anthropomorphism trigger positive user experiences. The results demonstrated that the deeper the self-disclosure depth was, the more intimate and humanly the agent was perceived and the more positive the user experience was. In addition, the effect of self-disclosure depth on anthropomorphism and positive user experience was completely mediated by intimacy. This means that when using a computer with interpersonal characteristics, people anthropomorphize it and have a positive experience because people react socially to objects with social cues. This study bridges the gap between the CASA paradigm and anthropomorphism research, suggesting the possibility of psychological explanations for the principle of human-computer interactions. In addition, it explicates the mechanism of anthropomorphism and positive user experience, emphasizing the importance of social response-that is, intimacy.

The performance of natural smoke ventilators in High-rise buildings was analyzed by investigating the stack effect depending on the wind velocities using CONTAMW tool. The results showed that the opening of smoke ventilators can influence on the stack effect in the building thus moving the position of the neutral plane toward the opened smoke ventilators. The outside wind velocities can move up the neutral plane toward the top of the building thus increasing pressure differentials at the bottom of the building. The smoke ventilators can maintain its normal performance without outside wind, however, strong outside wind can prevent natural smoke exhaust due to the infiltration of outside air at the ventilators.

The method described offers rapid and efficient sample preparation using on-line microwave digestion of metal oxides in water sample with direct elemental detection by ICP-AES. The open tubing digestion system(OTD) and the restraint tubing digestion system(RTD) for flow injection(FI) were designed and tested to find the optimum conditions. Comparison of OTD and RTD indicated that RTD was 3 times faster on the digestion time, and 10 times higher on sample mass. Finally, the results of RTD agree well with those by conventional microwave open vessel in all cases and show good precision; Fe and Cu show good with about 5% of RSD, while Zn and Co more or less than 10% RSD.

This paper tries to explore the impact of economic globalization on social capital accumulation. To investigate direct effect, we build a model and derive a proposition which can explain the relative decline in social capital brought about by market expansion. Besides direct effect, we also explore channel effect through democracy, government size, education attainment, and inequality. We estimate direct and channel effect of globalization using cross section of 65 countries data time period 1980-1999 using three-stage least squares(3SLS). Results are in line with predictions and clearly support that globalization significantly and negatively affects social capital accumulation. Channel effect also shows that globalization has a negative effect through aggravating income inequality while it has a positive effect through higher education attainment, higher level of democracy and larger government spending. Such a net negative channel effect reinforces our prediction. As a robustness check we estimate other sets of data and the result strongly supports our theory.
