This paper examines the conventional notion of natural beauty and its legacy on the aesthetic experience of nature and landscape architecture in terms of critical perspective. We can take its clue for discussion from the our routine convention of experiencing natural beauty from the picture-like nature. We often equate natural beauty with superficial representations of nature shown in pictures. However, it is no more than a by-stander's nature seen purely through the eyes of the outsider. Problems of the picture-like nature can be summarized as the contemplative and visual-oriented aesthetic experience of landscape, which has had its influence not only on the ways of seeing the natural beauty but also on the ways of making it. The tradition of the picture-like nature has been transplanted into the real world through the practice of landscape architecture. It has been mass-producing superficial beauty of nature, focused on visual form. Landscape architecture in such a form is just a static means of decoration devoid of meaning and content.

Dental caries is a biofilm-related oral disease, and continues to afflict the majority of the world's population. Although fluoride, delivered in various modalities, remains the mainstay for the prevention of caries, additional approaches are required to enhance its effectiveness. Natural products have been used as a major source of innovative and effective therapeutic agents throughout human history, and have shown promise as a source of components for the development of new drugs. In addition. studies using natural products to prevent or treat oral diseases such as dental caries have received a great deal of attention. A number of compounds, such as epicatechin, allicin and sanguinarine, isolated from natural products, have also been investigated for their efficacy against oral microbial pathogens. However, the use of natural products as an anti-caries agent in clinical practice was controversial because of inadequate knowledge concerning their mechanisms of action and chemical characterization. This study focuses on the current knowledge of natural products in dental caries prevention and suggests natural products are importance sources for the prevention of dental caries.

We have known that ethno-mathematics is a field of a study that emphasizes the socio-cultural environment in which a person "does" mathematics as stated by D'Ambrosio(Ethno mathematics and its Place in the History and Pedagogy of Mathematics, 1985). Measurement is an important mathematical topic, which leads students to relate math to the eal-world applications, particularly with socio-cultural aspects. The purpose of this article is to review the history of the measurement system in Korea briefly and to adapt the measurement system into real-world problems so that children acquire measurement knowledge in the most natural way.

A new normalized MBD algorithm is presented for nonstationary convolutive mixtures and its properties/modifications are discussed in details. The proposed algorithm normalizes the signal spectrum in the frequency domain to provide faster stable convergence and improved separation without whitening effect. Modifications such as nonholonomic constraints and off-diagonal learning to the proposed algorithm are also discussed. Simulation results using a real-world recording confirm superior performanceof the proposed algorithm and its usefulness in real world applications.

20세기 이후 과학기술의 급속한 발전에 따라 인간의 자연적, 신체적 한계를 기술을 통해 극복하려는 시도가 점점 가속화된다. 트랜스휴머니즘은 이러한 인간의 기술적 시도를 적극적으로 지지하고 긍정하는 운동이다. 그러나 트랜스휴머니즘의 기술에 대한 낙관적 태도는 이를 통해 인간의 자연적 본성이 파괴되고, 인간의 가치가 심하게 훼손될 수 있다는 반대론자들의 강한 저항에 부딪히게 된다. 트랜스휴머니즘 논란의 초점은 기술이 인간에게 어떠한 의미를 갖느냐는 것이다. 그러나 트랜스휴머니즘의 정확한 이해를 위해서는 우선 기술과 인간이 한데 어우러져 있는 우리의 '생활세계'에 대한 고찰이 선행되어야 한다. 생활세계는 모든 인간의 실천적 활동의 바탕이 되면서 동시에 이의 산물을 그 자체 안에 포괄하는 개방적이고 포용적인 세계이다. 후설에 따르면 생활세계속으로 인간의 산물이 포함되는 과정은 일종의 '친숙화' 과정으로서 이를 통해 특정 이론이나 기술 등은 생활세계 속에서 우리의 삶과 조화로운 결합을 이루면서 동시에 상대화된다. 이러한 기술의 생활세계로의 편입 및 친숙화는 기술의 인간화 과정이며, 인간과 생활세계의 유한성과 조응하는 과정으로도 볼 수 있다. 이런 맥락에서 볼 때, 트랜스휴머니즘적 시도는 생활세계 속의 인간의 자연스러운 실천의 과정으로서 이에 대해 지나치게 우려할 것도 아니지만 또 과도하게 맹신해서도 안 될 것이다.

We characterized the human endogenous retrovirus (HERV-W) family in humans and primates. In silico expression data indicated that 22 complete HERV-W families from human chromosomes 1-3, 5-8, 10-12, 15, 19, and X are randomly expressed in various tissues. Quantitative real-time RT-PCR analysis of the HERV-W env gene derived from human chromosome 7q21.2 indicated predominant expression in the human placenta. Several copies of repeat sequences (SINE, LINE, LTR, simple repeat) were detected within the complete or processed pseudo HERV-W of the human, chimpanzee, and rhesus monkey. Compared to other regions (5'LTR, Gag, Gag-Pol, Env, 3'LTR), the repeat family has been mainly integrated into the region spanning the 5'LTRs of Gag (1398 bp) and Pol (3242 bp). FISH detected the HERV-W probe (fosWE1) derived from a gorilla fosmid library in the metaphase chromosomes of all primates (five hominoids, three Old World monkeys, two New World monkeys, and one prosimian), but not in Tupaia. This finding was supported by molecular clock and phylogeny data using the divergence values of the complete HERV-W LTR elements. The data suggested that the HERV-W family was integrated into the primate genome approximately 63 million years (Myr) ago, and evolved independently during the course of primate radiation.

Kimchi is a traditional Korean vegetable product that is naturally fermented by various microorganisms present in the raw materials. Among these microorganisms, lactic acid bacteria dominate the fermentation process. Natural fermentation with unsterilized raw materials leads to the growth of various lactic acid bacteria, resulting in variations in the taste and quality of kimchi, which may make it difficult to produce industrial-scale kimchi with consistent quality. The use of starter cultures has been considered as an alternative for the industrial production of standardized kimchi, and recent trends suggest that the demand for starter cultures is on the rise. However, several factors should be carefully considered for the successful application of starter cultures for kimchi fermentation. In this review, we summarize recent studies on kimchi starter cultures, describe practical problems in the application of industrial-scale kimchi production, and discuss the directions for further studies.

This study aims to examine the symbolism of the emblems of World Expositions by using Victor Turner's symbolic theory as a research method, and to reveal the symbolic types behind them by classifying the emblem designs of different periods and themes. The research object is 12 comprehensive World's Fair emblems from the 1939 New York World's Fair in the United States to the 2025 Osaka World's Fair in Japan, as identified by Bureau International des Expositions. The research method mainly adopts documentary research to collect historical information and theoretical frameworks related to the design of World's Fair emblems. In the analysis process, Victor Turner's symbolic sign theory is used as the main analytical framework to link the design elements of emblems to their relevance to specific societies and cultures in order to reveal the themes, values and ideas represented by the emblem symbolism. The results of the study show that the design of the Expo emblem uses different symbols, including material symbols, behavioral symbols, sensory symbols, natural symbols, social symbols and virtual symbols, to convey the core concepts, themes and values of the Expo. Through different types of symbols, the Expo emblem shows a wide range of concerns about technology and the future, mankind and the world, nature and ecology, and society and innovation. The symbolic design of the emblem plays an important role in conveying the core concept and theme of the Expo.

기후변화 위기상황에서 습지 생태계의 기후변화 완화 및 적응 기능이 더욱 강조되고 있으며, 탄소흡수원으로서 갯벌의 생태계 서비스가 중요시되고 있다. 현재 황해지역 갯벌 중 남한과 중국의 경우 UNESCO 세계자연유산 2단계 등재를 위한 준비를 하고 있으며, 향후 황해지역 갯벌을 통한 남북한 및 중국의 초국경협력이 기대되는 상황이다. 그러나 이동성 조류 서식지, 휴식지, 중간기착지로서 황해지역 갯벌의 중요성과 보전, 관리, 남북한 및 중국의 협력체계에 관한 연구는 부족한 상황이다. 이에 본 연구에서는 UNESCO 세계자연유산으로 등재된 남한의 서남해안 갯벌과 중국의 옌청자연보호구, 잠정목록에 등재된 북한의 문덕 습지보호구를 포함한 황해지역 갯벌을 중심으로 남북한 및 중국의 생태계 보전 협력 여건을 분석하였다. 이를 바탕으로 이동성 조류 서식지, 휴식지, 중간기착지로서 황해지역 갯벌의 중요성과 황해 연안습지 주요 특징, 북한과의 협력여건 등을 분석하여 황해 연안습지의 초국경보전지역 등재를 위한 생태계 보전 협력 방향을 제시하였다
