  • From the Darwinian perspective, all the human behaviors and thoughts are operated by "the selfish gene," the term coined by Richard Dawkins, which has long been evolving to survive by utilizing the limited quality and quantity of resources. And an organism which fails to regenerate by creating its "replicator" is doomed to extinction, for gene combinations which help an organism to survive and reproduce tend to also improve the gene's own chances of being passed on through generations. Dawkins also coins the term "meme" for a unit of human cultural evolution analogous to the gene, suggesting that such selfish replication may also be the principle for human culture. Ian McEwan is not only a controversial but more importantly influential writer in the 21st century academic world. His 1997 book Enduring Love is not exceptional in that it draws both literary and scientific attention. Intentionally set up with the dynamic conflict between the two cultures, namely art and science, the book explores the way in which the state of the modern minds is misinterpreted and estranged by each other. In this novel, the three main protagonists, Joe, Clarissa, and Jed, each representing the very important three elements of human civilization-cognition/science, emotion/art, and faith/religion-meet an unexpected peril of life. The author of the novel employs the narrative of evolutionary science-in particular the narratives of gene and meme-to provoke the question of the two cultures famously addressed by Snow in the mid 20th century and the further discussions followed by the later Darwinian scholars such as Richard Dawkins. In this paper I aim to illustrate the way in which the author develops the idea of gene science and literature and how he proceeds to provide a sophisticated bridge between the two cultures and induce a kind of consilience by the recurrent name of love in the story of Enduring Love.

  • The purpose of this study is to formulate a concept of naturalism in fashion and verify the design characteristics found in such designs via reviewing the concept of naturalism and its influence on dress making in different periods in history. The references from various academic fields including philosophy, literature and fine arts were used to examine how the naturalism was formulated over the years. This study was then to identify the naturalistic influences by closely examining various Western dress codes found in literature, publications and actual samples. The results of this study shows that the close examination of naturalism in fashion with the changes of times displayed the complex evolution process over the years, and they were classified by four distinctive categories; Retro, Ecology, Primitive and Ethnic. Naturalism in the contemporary fashion design showed higher frequency of adopting ecological and retro styles, especially retro style adoption being on the rise, combining wide range of partial components of each style. The color usage showed the skewed concentration on YellowRed, Red and Yellow colors with pale, light grayish and grayish tones.

  • In this study, we investigated the evolution and reduction of the surface roughness during the high-speed chemical dry thinning process of Si wafers. The direct injection of NO gas into the reactor during the supply of F radicals from NF3 remote plasmas was very effective in increasing the Si thinning rate, due to the NO-induced enhancement of the surface reaction, but resulted in the significant roughening of the thinned Si surface. However, the direct addition of Ar and N2 gas, together with NO gas, decreased the root mean square (RMS) surface roughness of the thinned Si wafer significantly. The process regime for the increasing of the thinning rate and concomitant reduction of the surface roughness was extended at higher Ar gas flow rates. In this way, Si wafer thinning rate as high as $20\;{\mu}m/min$ and very smooth surface roughness was obtained and the mechanical damage of silicon wafer was effectively removed. We also measured die fracture strength of thinned Si wafer in order to understand the effect of chemical dry thinning on removal of mechanical damage generated during mechanical grinding. The die fracture strength of the thinned Si wafers was measured using 3-point bending test and compared. The results indicated that chemical dry thinning with reduced surface roughness and removal of mechanical damage increased the die fracture strength of the thinned Si wafer.

  • A gene coding for triosephosphate isomerase (TPI) from a rat skeletal muscle cDNA library was cloned and its nucleotide sequence was determined. The 1, 348-bp cDNA clone contains 24 bp $5^I$ noncoding region, the entire 750 bp coding region corresponding to a protein of 249 amino acids, $547bp 3^I$ noncoding region and part of a poly(A) tail. It also contains a polyadenylation signal, AATAAA, starting from 17 bp upstream of the poly(A) tail. The calculated molecular weight of rat TPI is 27.8 kDa and the net charge is +4. The deduced amino acid sequence from rat TPI CDNA sequence has 93% and 94% homology with that of mouse and human clones, respectively. The amino acids at the residue of Asn12, Lys14, His96, Glu 166, His96, His101, Ala177, Tyr165, Glu13O, Tyr2O9, and Ser212 in catalytic site are completely identical, confirming that the functional residues in TPI proteins are highly conserved throughout evolution. The most profound characteristic of rat TPI enzyme, compared with other TPIs, is that there are five cysteine substitutions at the residue of 21, 27, 159, 195 and 204. A Glu123 instead of Gly was found in rabbit, rhesus, mouse and human sequences. Through the method of RT-PCR, the mRNA transcription level of TPI gene was found to be different among various tissues and was highest in muscle.

  • The human instinct toward nature is biophilia as a psychological term. There have been a number of empirical evidences confirmed that natural features in buildings enhance human's comfort focusing on biophilia. However, the evolution of society, science, and industry has separated modern buildings from nature. Therefore, this paper addresses the assumption that the admiration for historical buildings in contemporary society is attribute to the qualities of biophilic design. Prospect and refuge, one of the strategies for biophilic design, ultimately provides the opportunity to recover from stress and tension. The purpose of this study is to figure out elements of prospect and refuge based on the design theory of biophilia for psychological healing. This study explores the Gyeongbokgung Palace with the design elements of prospect and refuge in biophilia. It also measures these elements quantitatively with the contrast using Adobe Photoshop CS6, and the area ratio of prospect and refuge. The results of this research verify that the conflicting characteristics of prospect and refuge are identified simultaneously, it is significant to attract people. Gangnyeongjeon Hall and Gyotaejeon Hall, the living quarters for the king and queen, propose the intense pattern of refuge characteristics more than other areas. The mathematical properties of the area ratio show that the pattern of prospect-refuge characteristics change in particular design elements.

  • The aims of this study were to Investigate the floor impact noise isolation performance of floating floor with isolation materials and propose the improvement direction of floor impact noise measurement method and evaluation classes using impact ball. Reduction of light-weight impact sound pressure level can be achieved by the finishing materials, such as vinyl finishing material and wooden flooring with isolation materials. Floor impact noise Isolation material which satisfy the properties of the floor impact noise isolation materials cause resonance in the low frequency band and worsen heavy-weight impact sound pressure level. Heavy-weight impact sound level can be reduced by using noise reduction flooring, ceiling and increase of slab thickness. Strong impact force in low frequency bang below 63Hz of bang machine is not similar to human impact source and causes some problem in evaluating heavy-weight impact noise but heavy-weight impact noise measurement and evolution using impact ball which is very similar to human impact is more reliable than bang machine. Correction value on the background noise and sensitivity of residents should be considered on the floor impact noise evaluation classes.

  • We report the terahertz time-domain spectroscopy (THz-TDS) of transdermal drug delivery in human skin. The time evolution of transdermal nicotine delivery in nicotine patches was assessed by detecting the transmission coefficient of sub-picosecond THz pulses and using a semi-analytic model based on the single-layer effective medium approximation. Using commercial nicotine patches (Nicoderm CQ®, 7 mg/24 h), THz transmission coefficients were measured to quantitatively analyze the cumulative amounts of nicotine released from the patches in the absence of their detailed specifications, including multilayer structures and optical properties at THz frequencies. The results agreed well with measurements by conventional in vitro and in vivo methods, using a diffusion cell with high-performance liquid chromatography and blood sampling respectively. Our study revealed the ability of the THz-TDS method to be an effective alternative to existing methods for noninvasive and label-free assessments of transdermal drug delivery, showing its high promise for biomedical, pharmaceutical, and cosmetic applications.

  • With the evolution of containerization and globalization of supply chains, aspects of port functions have made the transition from the sea to the inland region that forms the dry port. To explore the relationship between dry ports and regional economic development, this study uses a gravity model and forecast model to analyze 1,040 observations in 104 cities (22 dry port cities) along the Yangtze River Economic Belt (YREB) from 2008 to 2017. The model includes economic variables, logistics variables, foreign relations variables, and human capital variables. It was found that the dry port is positively correlated with trade volume. Compared with a city without a dry port, the trade volume of a city with a dry port will increase 0.099 times. It can be concluded that a dry port is crucial for the economic development of the YREB. It was also found that per capita GDP as an economic variable, road area and rail number as logistics variables, and foreign relation variables are positively correlated with trade volume, while the human capital variable has no significant effect on trade volume. In addition, governmental policy implications are addressed from the aspects of dry port and industry cluster caused by foreign investment.
