Chinese literature once had its splendid era in the Tang and Song Dynasties culminating in Tang poetry and influencing the literatures of its neighboring countries. However, during the past centuries, it has largely been "marginalized" on the map of world literature. On the one hand, large numbers of foreign literary works, especially those from Western countries, have been translated into Chinese, exerting a huge influence on the formation of a sort of modern Chinese literary tradition. On the other hand, few contemporary Chinese literary works have been translated into the major foreign languages. With the help of the rise and flourishing of comparative literature, contemporary Chinese literature has been moving toward the world and had its own Nobel laureate. The author, after analyzing the reasons why Chinese literature has been "marginalized," argues that Chinese literature will develop steadily in the age of globalization. Globalization in China has undergone three steps: first, it has made China passively involved in this irresistible trend; second, the country has then quickly adapted itself to this trend; and third, China has started to play an increasingly leading role in the first decade of the present century. In this way, contemporary Chinese literature and comparative literature studies will steadily develop with the help of the "Belt and Road" initiative.

Sweet dough bread is made by using sponge & dough method with the sweet dough formula which consists of wheat gluten and baking powder. The effect of wheat gluten and baking powder to the bread has been studied after the dough frozen, stored, thawed, fermented. and baked. The bread quality has been evaluated by measuring the product volute and also by the sensory evaluation after baking. When 4% of wheat gluten and 4% of baking powder were added into the dough. the bread has a larger volume than that of 2% wheat gluten and 2% baking powder in volume. However. wheat gluten shows better result than baking powder in terms of volume. In sensory evaluation, the bread has higher score when 2% of wheat gluten and 2% of baking powder were added into the dough than that of 4% wheat gluten and 4% baking powder. Consequently, breads show better result when 2% wheat gluten and 2% baking powder were added into the dough than that of 4% wheat gluten and 4% baking powder.

Graphene has attracted an increasing attention due to its extraordinary electronic, mechanical, and thermal properties. Especially, the two dimensional (2D) sheet of graphene with an extremely high surface to volume ratio has a great potential in the preparation of multifunctional nanomaterials, as 2D supports to host metal nanoparticles (NPs). Copper oxide is widely used in various areas as antifouling paint, p-type semiconductor, dry cell batteries, and catalysts. Although the copper oxide(II) has been well known for efficient catalyst in C-N cross-coupling reaction, copper oxide(I) has not been highlighted. In this research, CuO and Cu2O nanoparticles (NPs) dispersed on the surface of grapehene oxide (GO) have been synthesized by impregnation method and their morphological and electronic structures have been systemically investigated using TEM, XRD, and XAFS. We demonstrate that both CuO and Cu2O on graphene presents efficient catalytic performance toward C-N cross coupling reaction. The detailed structural difference between CuO and Cu2O NPs and their effect on catalytic performance are discussed.

The conventional methods of boundary-conformed 2D surfaces generation usually yield some problems. This paper deals with two boundary-conformed 2D surface generation methods, one conventional approach, the linear Coons method, and a new method, boundary-conformed interpolation. In this new method, unidirectional 2D surface has been generated using some of the geometric properties of the given boundary curves. A method of simultaneous displacement of the interpolated curves from the opposite boundaries has been adopted. The geometric properties considered for displacements include weighted combination of angle bisector and linear displacement vectors at all the data-points of the two opposite generating curves. The algorithm has one adjustable parameter that controls the characteristics of transformation of one set of curves from its parents. This unidirectional process has been extended to bi-directional parameterization by superimposing two sets of unidirectional curves generated from both boundary pairs. Case studies show that this algorithm gives reasonably smooth transformation of the boundaries. This algorithm is more robust than the linear Coons method and capable of resolving the 2D boundary-conformed parameterization problems.

Five free-living nematode species belonging to the order of Rhabditida are described for the first time in Korea. Two unrecorded species of Rhabditidae, Cruznema tripartitum (Linston, 1906) Zullini, 1982, and Poikilolaimus oxycerca de Man, 1895, and one species of Peloderidae, Pelodera strongyloides Schneider, 1860, were collected in Korea. C. tripartitum has nine pairs of genital papillae arranged in 2+2+1+4 differently from similar species of C. scarabaeum which has ten genital papillae arranged in 2+1+4+3. Poikilolaimus oxycerca has shorter tail (shorter than anal body diameter) compared to similar species of P. regenfussi which has longer tail(longer than anal body diameter). Pelodera strongyloides has shorter tail(1-1.5 times anal body diameters long) than P. punctata (4 anal body diameters long). Two unrecorded species of Panagrolaimidae, Panagrolaimus apicatus Schuurmans Stekhoven & Teunissen, 1938 and Panagrolaimus rigidus (Schneider, 1866) Thorne, 1937 were collected in Korea. P. apicatus has rounded and lower lip compared to similar species, P. margaretae Massey, 1964 which has finely pointed lip. P. rigidus has slender tail and lips rounded and flat barely separated when compared to similar species, P. subelongatus(Cobb, 1914) Thorne, 1937 which has plumper tail and lips are well separated.

Solubility on $(LiBr+CaCl_2)$ in water has been measured systematically and compared with those of pure LiBr. It has been observed that there exists optimum value of $CaCl_2(LiBr+CaCl_2)$ in solubility when total$(LiBr+CaCl_2)$ concentration is higher than 57wt%. As total concentration increases up to 65wt%, it is found that the optimum value also increases monotonically. From the experimental results, a master plot has been constructed, with which optimum ratio of LiBr to $CaCl_2$ can be found in terms of total concentration. Vapor pressure of $H_2O/(LiBr+CaCl_2)$ solution with optimum contents of $CaCl_2$ has been observed to be changed negligibly at relatiely low temperature. However, as temperature increases, it is found that increasement in vapor pressure is significant.

The atomic structure of Sb/Si(5 5 12)-$2{\times}1$ surface, deposited at room temperature (RT) and post-annealed, has been identified by scanning tunneling microscopy and the corresponding interface has been studied by synchrotron core-level photoemission spectroscopy. With 0.3-nm Sb deposition at RT and postannealing at $600^{\circ}C$, the surface has been facetted to (225)-$2{\times}1$ and (112)-$1{\times}1$, and its Si 2p has shown that all the Si 2p surface components have disappeared, while the single Sb-Si interfacial component has appeared. Such results indicate that all of surface Si atoms are replaced by Sb atoms and the charge is transferred from Si to passivating Sb-atoms at the top layer. With subsequent postannealing up to $700^{\circ}C$, the surface has been facetted to (113)-$2{\times}2$ and (335)-$4{\times}2$, still having Sb-Si interfacial component and partially re-exposed Si surface components. From the present study, the role of surfactant atom, Sb, as well as the thermal-stabilization of Sb-passivated high-index Si surface will be exposed. Especially, the key role of the Sb/Si(113)-$2{\times}2$, composed of Rebonded-Dimer-Rebonded atom 1D structures, for stabilization will be discussed.

The Daehyun sericite deposit in socheon-myun, Bongwha-gun, Kyungsangbuk-do, Korea, has been formed by the hydrothermal alteration of the Hongjesa granite of Precambrian age, leaving the muscovite granite between ore body and the Hongjesa granite as the wall rock alteration zone. The process of sericitization of granitic rock as well as chemistry and structures of sericites were studied using polarizing microscope, X-ray diffractometer (XRD), electron probe microanalyzer (EPMA) and high resolution transmission electron microscope (HRTEM). There are two genetic types of sericites having different chemistry and structure. The early sericite is of 2M1 polytype and has octahedral composition close to muscovite. It has been formed from the primary muscovite, tourmaline and quartz under a relatively high temperature. The late sericite is of 1M, 2M1 and 3T polytypes and has phengitic composition. It has been formed form feldspar, biotite, muscovite and tourmaline under a relatively low temperature. Chemical analyses show t, the early sericite has less Mg+FeT content and lower Si/AlIV ratio in tetrahedral site than the late sericite.
