This paper considers the potential impact of biological approaches such as bio-copying (biomimetics) and biomanipulating (e.g. genetic engineering) on future developments in the field of textiles and, in particular, fibres. If analytical tools for studying biological systems combined with those of materials science are further developed, and higher efficiency and reproducibility of genetic engineering technology can be achieved, the potential for the copying and manipulation of nature for textile innovations will be immense. The present state for both fields is described with examples such as touch and close fastener, structurally coloured fibres, the Lotus of lect (for bio-copying), as well as herbicide tolerant cotton, insecticide resistant cotton (Bt cotton), cotton polyester bicomponent fibres, genetically engineered silkworm and silk protein, and spider fibres. (for genetic engineering).

It seems obvious to the contemporary eye that modern technology has finally brought chaotic abundance to the present world, and provided a superficial civilization over the last century. Nevertheless, such an argument about the external phenomena of present culture does not help constitute the right track of modern technology and architecture. Rather, this discussion comes to re-signify the importance of critical metaphysics as a part of man's cultural activities, especially the ontological meaning of them. In this point, the research is intended both to re-certify the essential nature and mythic value of technology through reviewing the ancient and modern philosophical contemplations, and to examine its architectural condition against the rapid expansion of commercial material-culture.

The dynamic nature of the World Wide Web challenges Information Retrieval System to find information relevant and recent. Intelligent agents can complement the power of search engines to deal with this challenge. In this paper, we explain in manner of building Information Retrieval System based on intelligent agent technology. We present a tool called Websearcher. It was performed in Java environment. The object-oriented nature of Java and built-in facilities for multi-thread decreased our implementation effort. A modular software design makes it easy to configure the system for various experiments.

The goal of this work is to create a new and improved GWO (Grey Wolf Optimizer), the so-called Robot GWO (RGWO), for dynamic and static target tracking involving multiple robots in unknown environmental conditions. From applying ourselves with the Gray Wolf Optimization Algorithm (GWO) and how it works, as the name suggests, it is a nature-inspired metaheuristic based on the behavior of wolf packs. Like other nature-inspired metaheuristics such as genetic algorithms and firefly algorithms, we explore the search space to find the optimal solution. The results also show that the improved optimal control method can provide superior power characteristics even when operating conditions and design parameters are changed.

이 논문은 포스트 게놈 시대에 합성생물학 연구자들과 트랜스휴머니스트들의 자연관과 진화개념을 비교분석하는 것을 목적으로 하고 있다. 2000년대 새롭게 등장한 합성생물학은 "합리적 설계"와 "방향적 진화"라는 두 가지 핵심적인 개념을 통해 생명 시스템을 디자인하는 것을 가능케 했다. 인간이 생명체를 설계해 만들어내고 진화과정을 가속화시킬 뿐만 아니라 특정 방향으로 유도한다는 점에서, 자연적인 것과 인공적인 것 사이의 경계가 무너지는 것 아닌가 하는 우려가 제기되었다. 이렇게 합성생물학으로 재구성된 자연을 어떻게 받아들여야 할 것인가? 진화의 속도와 방향에 영향을 주는 연구를 어떻게 정당화할 수 있는가? 합성생물학과 트랜스휴머니즘은 어떤 지적 자산을 공유하고 있나? 과학기술의 상업화와 같은 사회경제적 요소가 분야의 흐름에 영향을 주지는 않은지? 자연의 도덕적 권위는 사라졌는가? 본 논문은 합성생물학을 선도하고 있는 세 명의 과학자와 최근 대표적 트랜스휴머니스트로 떠오르고 있는 옥스퍼드 대학의 철학자들을 관점을 소개하고 비교분석하여 이 질문들에 답하려고 한다.

1990년대 사이버문학론의 전개과정은 문학장의 형성과 충돌, 집단지성을 통한 상징권력 추구와 욕망의 이중성을 극명하게 보여준다. 모든 욕망은 권력지향적일 수밖에 없는데, 사이버문학론은 네트워크-공간의 비평주체들이 공존의 인문학을 표방하면서 전개되었다는 점에서 의미가 있다. 1996년 "사이버문학의 도전" 출간과 계간 "버전업"의 창간으로 본격화된 사이버문학론은 인공자연의 탄생을 예술의 변화와 연결 지으려는 학문적 시도였지만 문학장을 형성하게 된 배경에는 현실공간의 문학장이 가상공간을 영토화하려는 시도를 막고, 자체적으로 문학장을 형성하려는 상징권력에 대한 욕망이 강하게 자리잡고 있었다. 사이버문학론의 실패는 현실공간과 가상공간 사이에서 비평권력의 모순된 욕망이 충돌했기 때문이다. "버전업"은 본격문학과 사이버문학에 대한 사회적 구별짓기, 곧 계급적 차별화를 해소하고자 시도하였으나 스스로 본격문학을 닮아감으로써 오히려 계급적 차별화를 공고히 했다. 90년대 사이버문학론은 상징권력에서 드러난 욕망의 모순과 구별 짖기의 한계는 분명하지만 인공자연의 탄생에 대한 최초의 문학적 대응이었다. 문학 담론은 항상 당대의 사회적 조건(기술적 진보를 포함하는)과 예술 텍스트의 관계를 탐구해 왔다. 인공자연의 문학장 안에서 전체를 아우르는 새로운 비평담론을 생산하는 것은 기술편집시대 문학의 중요한 과제이며, 인문학과 기술이 공존해야 하는 당위이다.

As the discourse on Anthropocene grows, this exploratory research investigates the interrelationship and interconnectivity between humanity and technology by analyzing a sound art installation created by the author. Crying Sea is a sound installation that uses plastic wastes collected from the shore to create symbolic narratives and artistic experience connecting humans, objects, and nature through interactive digital technology. In this installation, the audiences are guided to walk over the wastes, and the sounds created by the footsteps are recorded in real-time, which then are distorted and amplified into disturbing sounds through speakers filling up the room. In analyzing this artwork, three theories from technological, philosophical, and ecological backgrounds were used; specifically, Bernard Stiegler's pharmakon theory, Dona Haraway's cyborg manifesto, and Timothy Morton's dark ecology theory. A common factor revealed from all three theories by analyzing the Crying Sea is that humans, technologies, and all other entities within nature are interconnected and resonated. The awareness of this recursive relationship allows us to consider sustainable balancing.

The objective of this study is to seek for improvement measures to make the Ecosystem and Nature Map by analyzing causes for grade changes and distributional characteristics of areas with public objections to the Ecosystem and Nature Map notified by e-official gazette from 2014 to June 2016. The receipt of public appeals has been recently increased from average 23 cases a year(2007-2013) to average 33 cases a year(2014-June 2016) while there were 42 areas with public appeals for less than the minimum area($62,500m^2$) for the evaluation of grade of the Ecosystem and Nature Map. Most of the public appeals focused on the 1st grade zone of the Ecosystem and Nature Map. Before grade changes by public appeals, the 1st grade zone of the Ecosystem and Nature Map were 76.0% of the whole areas with public appeals. However, after grade changes by public appeals, it was rapidly decreased to 25.2%, which means that a lot of the 1st grade zone with public appeals were lowered. In the results of analyzing the distributional characteristics of areas with public appeals, they were mostly distributed in lowland(less than 250m altitude), section with $10{\sim}20^{\circ}$ slope, and areas close to or within 100m from built-up area. Regarding areas with public appeals, the biggest time difference between the period of the existing research by National Ecosystem Survey and the period of notice after completing the treatment of public appeals was 18 years while areas showing 6-15 years of time difference were about 70%. Thus, there were huge differences in time of research and notice. Also, the biggest causes for grade changes were boundary errors caused by small-scale survey, and then followed by changes in evaluation of endangered species and occurrence of built-up area and damaged land. Analyzing areas with public appeals in each evaluation item of the Ecosystem and Nature Map, vegetation part was 73.0%, and endangered species area was 23.1% while topography and wetland was less.

Crime is not a completely random event but rather shows a pattern in space and time. Capturing the dynamic nature of crime patterns is a challenging task. Crime prediction models that rely only on neighborhood influence and demographic features might not be able to capture the dynamics of crime patterns, as demographic data collection does not occur frequently and is static. This work proposes a novel approach for crime count and hotspot prediction to capture the dynamic nature of crime patterns using taxi data along with historical crime and demographic data. The proposed approach predicts crime events in spatial units and classifies each of them into a hotspot category based on the number of crime events. Four models are proposed, which consider different covariates to select a set of independent variables. The experimental results show that the proposed combined subset model (CSM), in which static and dynamic aspects of crime are combined by employing the taxi dataset, is more accurate than the other models presented in this study.
