본 논문은 청계천 복원과 재개발이 지속가능한 도시 서울을 건설할 수 있는가를 다루고 있다. 지속가능한 도시가 되기 위해서는 경제성, 생태성 그리고 사회성을 가져야 한다. 서울시에 의해 주도된 청계천복원과 재개발은 경제성을 우선하여 생태성과 사회성을 강조하는 사회 세력들을 소외시키고 생태성과 사회성을 저하시키고 있다. 이는 지속가능한 도시상과는 거리가 있다. 궁극적으로 자본주의하에서 자본의 축적과 발전에 따른 생산조건들의 지속적인 파괴에 의해 지속가능한 도시의 건설은 거의 실현되기 어려운 것처럼 보인다. 생산조건의 파괴를 막고 지속가능한 도시를 건설하기 위하여 본 논문은 자본의 축적과 발전 그리고 그것에 조응하는 서울시 주도로 진행되는 청계천 복원과 재개발을 넘어 소외된 사회집단들, 사회-환경단체들 그리고 여론의 참여적인 틀을 만들어 실행할 것을 제안한다. 이러한 확장된 참여적인 틀은 자본주의하에서 지속가능한 도시건설의 가능성을 높인다.
Impact of Quality Factors on Platform-based Decisions

As platforms become primary decision making tools, platforms for decision have been introduced to improve quality of decision results. Because, decision platforms applied augmented decision-making process which uses experiences and feedback of users. This process creates a variety of alternatives tailored for users’ abilities and characteristics. However, platform users choose alter- natives before considering significant quality factors based on securing decision quality. In real world, platform managers use an algorithm that distorts appropriate alternatives for their commercial benefits. For improving quality of decision-making, preceding researches approach trying to increase rational decision -making ability based on experiences and feedback. In order to overcome bounded rationality, users interact with the machine to approach the optional situation. Differentiated from previous studies, our study focused more on characteristics of users while they use decision platforms. This study investigated the impact of quality factors on decision-making using platforms, the dimensions of systematic factors and user characteristics. Systematic factors such as platform reliability, data quality, and user characteristics such as user abilities and biases were selected, and measuring variables which trust, satisfaction, and loyalty of decision platforms were selected. Based on these quality factors, a structural equation research model was created. A survey was conducted with 391 participants using a 7-point Likert scale. The hypothesis that quality factors affect trust was proved to be valid through path analysis of the structural equation model. The key findings indicate that platform reliability, data quality, user abilities, and biases affect the trust, satisfaction and loyalty. Among the quality factors, group bias of users affects significantly trust of decision platforms. We suggest that quality factors of decision platform consist of experience-based and feedback-based decision-making with the platform's network effect. Through this study, the theories of decision-making are empirically tested and the academic scope of platform-based decision-making has been further developed.

As men age, andropause is the gradual decline in testosterone production with increasing age. The symptoms of andropause include the loss of physical and psychological activity. Some studies of anti-andropause therapy have mentioned significant process in reducing the symptoms, but, the effects of natural substances are not fully studied. The objective of this study was to examine the effect of carob (Ceratonia Siliqua L.) extract on the symptoms of andropause by increasing serum testosterone levels and reducing andropause symptoms. Carob which belongs to the legume family, contains many vitamins and minerals, and has a high dietary fiber and protein content. We studied the effect of carob on 13-month-old aging male rats. After daily administration of carob for 4 weeks, testosterone levels, sperm counts, motor coordination were increased. Additionally, body weight and body fat mass were decreased in carob-fed groups compared with in untreated groups. Carob did not affect testicle weight, aspartate aminotransferase and alanine aminotransferase levels. Overall, these results suggest that carob is a safe and effective natural substance for the relief of andropause symptoms and may also improve a wide variety of other symptoms.

In this paper, the bit-error-rate (BER) performance of simple transmit diversity (STD) system using training sequences is investigated in spatially correlated rayleigh flat fading channels. A BER expression for the STD system is represented as a channel estimation error caused by noise as well as the temporal variation of the channel. The channel estimation error is analytically derived as a function of training sequence length and fading index. It is shown that the BER performance of the STD system is significantly decreased by the error due to temporal variation and improves as the length of training symbols increases and/or the frame length decreases.
지역사회에서의 저항과참여적 의사결정 구조의 변화에 대한 사례연구-고압 송전탑 설치와 지역주민의 저항을 중심으로-

The essay argues that local residents’ collective resistances contain strong potentials to change a structure of a related decision making, generate some institutions and develop participatory democracy. To prove this, I analyze the Miryang movement against the construction of power transmission tower as a case that partially changed monopolistic, exclusive and oppressive structures of decision making into participatory, consultative, furthermore consensual and open ones at the low level of electricity supply policy(the plan and enforcement of power transmission facilities). Combining the insufficient compensation for private lands under power transmission towers with a hazard of extremely low frequency, most movements against high voltage power transmission facilities had been developing from landowners’ individual suing for a fall in their land values into local residents’ collective resistances to prevent a value degradation of commons. In the process of the Miryang residents’ hard collective struggle for about ten years, they newly generated some participatory institutions and/or ones by participation(an explanatory meeting, a public hearing, a conflict analysis, a board for conflict mediation, a board for compensation mediation, a committee for site selection, legislative enactment for compensation and assistance of residents living near to power transmission facilities etc) participating in decision making processes, and contributed to an evolution of participatory democracy. 이 글은 지역주민의 집단적 저항이 관련 의사결정구조를 변화시키고, 법과 제도를 생산하고 참여민주주의를 발전시키는 강력한 잠재역량을 가졌다고 주장한다. 이를 증명하기 위해 우리나라 전기수급정책 하위수준(송·변전설비 설치)에서 실행되었던 독점적 배제적 억압적이었던 의사결정구조를 부분적으로나마 참여적 협의적 그래서 합의적인 보다 개방적인 것으로 변화시킨 밀양 송전선로건설 반대운동 사례를 분석한다. 선하지의 개인 토지에 대한 불충분한 보상과 함께 송전설비 전자파 인체위해성 논란이 결합되면서 대부분의 송전설비 반대운동은 토지가치 하락에 대한 토지소유주의 개별적 저항에서 훼손되어가는 공동자원을 지키려는 관련 지역주민의 집단적 저항으로 발전하고 있었다. 10여 년의 밀양주민의 강경한 집단투쟁 과정에서 주민들은 의사결정과정에 참여하여 참여적 혹은 참여에 의한 제도들(설명회, 공청회, 갈등영향분석, 갈등조정위원회, 전자파 리스크 커뮤니케이션, 제도개선추진위원회, 보상 조정위원회, 입지선정위원회, 송변전설비 주변지역의 보상 및 지원에 관한 법률 등등)을 새롭게 생산하여 참여민주주의의 발전에 기여했다고 평가할 수 있다.
