  • Utilizing both the existing observational data for Orion A and the TRAO $^{13}CO$, $^{12}CO$ data for $1^{\circ}{\times}1^{\circ}$ region centered on M42 collected in 2012, we found a clear piece of evidence for a collision of a cloud with the OMC-1. This cloud has a shape like a long cylinder of ${\sim}0.1pc{\times}2pc$ in size, and has a well developed train of clumps of about a few solar masses, and is situated in the dark dust complex between M42 and M43. The cloud's motion is analysed to be moving at about $2.6km\;s^{-1}$, and is calculated to transverse the Orion Nebula ~2 pc above from the nebula center, toward the direction of about $60^{\circ}$ to the line of sight. This cloud had undergone a tidal splitting about a million years ago and had formed a very thin and long cylindrical core well before being engaged in the collision. General implications of this phenomenon are discussed in relation to star formation mechanisms in the GMC.

  • In the Langmuir-Blodgett (LB) technique, a monolayer on the water surface is transferred onto a substrate, which is raised and dipped through the surface. From this, multilayers can be obtained in which constituent molecules are periodically arranged. The LB technique has attracted considerable interest in the fabrication of electrical and electronic devices. Many researchers have investigated the electrical properties of monolayer and multiplayer films. Dendrimers represent a new class of synthetic macromolecules characterized by a regularly branched treelike structure. Multiple branching yields a large number of chain ends that distinguish dendrimers from conventional star-like polymers and microgels. The azobenzene dendrimer is one of the dendritic macromolecules that include the azo-group exhibiting a photochromic character. Due to the presence of the charge transfer element of the azo-group and its rod-shaped structure, these compounds are expected to have potential interest in electronics and ptoelectronics, especially in nonlinear optics. In the present paper, we give pressure stimulation to organic thin films and detect the induced displacement current.

  • The Chinese Holstein cattle breed, an introduced breed in China, has been crossbred with native cattle breeds. We hypothesised that the Chinese Holstein local population in Beijing share haplotypes with native Asian cattle breeds, the result of a sudden population expansion in the recent past. We also hypothesised that crossbreeding and population expansion left traces that shaped the genetic makeup of the breed. Evaluation of this was performed by mitochondrial DNA (mtDNA) sequence analysis of Chinese Holstein cattle from Beijing (n = 41) and a comparison of them with the published mtDNA sequences (n = 293) of 14 Asian breeds with an emphasis on Chinese native cattle breeds. Three shared common haplotypes between Chinese Holstein cattle and native Asian cattle were found. Moreover, a high level of haplotype diversity in Chinese Holstein cattle (h = 0.9557) and low nucleotide diversity (${\pi}$ = 0.0052) was found, indicating a past population bottleneck followed by rapid population growth. These findings are supported by the significantly negative deviation of Tajima's D (-1.82085), the star-like pattern of dominant haplotypes and the pairwise mismatch distribution analysis, which showed a unimodal pattern.

  • The purpose of this study is to examine the current situation of IMC strategies of Korean fashion brands which enter into Chinese market and to propose the efficient IMC strategies. Twenty Korean fashion brands which enter into Chinese market were selected and in-depth interviews with the managers were conducted. First, advertising is focused on magazines, and outdoor advertising, advertising in departments' magazines, distributing catalogs, and star marketing are performed in some cases. Brands often execute sales promotion activities such as price deduction, offering coupons, and presenting gifts. PR activities like events and sponsorship marketing which targets uncertain public or loyal customers are performed. PPL is conducted passively though it can be very effective. CRM is not operated systematically and customer management is conducted through tele-marketing and direct mail by shop managers. Web sites of brands have insufficient contents and are operated ineffectively. VMD follows brand's basic policy, but in cases of agents whose copyrights are transferred or branches which are place in areas where managing them is hard, shop managers operate their stores by themselves. Finally, because of socialistic consciousness, the perception about service of sales people is lacked.

  • Philp Lim, Alexander Wang and Jason Wu are the American fashion designers as descendants of Chinese immigrants. They had the honor of being given the Swarovski Awards- new premier fashion designer- from CFDA(Council of Fashion Designers of America). The purpose of this study were to investigate the characteristics of their collection, and offered the informations for Korean designers entering the American market. This research categorized characteristics of these designers'- whole characteristics and the characteristics of details such as formal characteristics, optimistic characteristics, tactile characteristics-, and fashion styles from the S/S season of 2009 to the F/W season of 2010 were analyzed. These young and male designers being received attention as a star, didn't make creative art pieces. But they made pragmatic, commercial, and con-temporary works in whole characteristics and succeeded in their fashion business like other American designers. On the other hand they oriented high fashion clearly in terms of the detail characteristics - their own accent color, tiny change in variety, unique material, delicate ornaments. Therefore Lim created chic and stylish, Wang made a sporty street style, Wu made a luxury style with mannish and casual through work characteristics suitable for their costumer.

  • In this paper, I propose that the figurative structure of Tongjoo Yoon′s "One Night, Counting the Stars" reflects the poet′s anguish over the colonial reality of Korea in the later stages of the Japanese occupation, especially regarding the forced adoption of Japanese names in 1939. The poet Yoon himself registered at Yonhi College with an adopted Japanese name. In the second half of the poem, the speaker alludes to this historical fact when he confesses that "On a hill lit by myriads of stars / I spelled my name / And covered it over with dirt," and that he "laments (his) shameful name." In the simile of the last stanza, the speaker continues to allude to the "buried" name: "But past winter, come spring to my star, / As green grass sprouts on a grave mound, / So will it spread with pride / On the hill where my name is buried." The longing and the yearning, expressed so simply and in child-like manner in the first half of the poem, become in the second half an urgent need for something that should have been but cannot be, and yet will be in the future-for a world that should be, now lost but to be regained. The poem contains the poet′s earnest belief that the inherited Korean names that were then so shamefully taken away will one day be recovered. It is almost impossible to find any other work written in Korean (despite the most suppressive measures against the use of the Korean language) that also alludes to the adoption of Japanese names. In this respect, "One Night, Counting the Stars" has a unique value in the history of modem Korean literature.

  • This paper introduces a serious game called freCman developed for C programming language beginners. Since key words, syntax, and programming structure of C programming language are unfamiliar for them, they feel uneasy and have many difficulties to study. We developed three games such as shooting star C, finding hidden errors, unscrambling C codes through which C beginners can study C language easily. Also we developed CTS(Code to Speech) which speeches C source codes like English statements so that C beginners can be familiar with C key words and statements. To prove effectiveness of the freCman, some experiments have been conducted with C language beginners. Experiment results show that the freCman helps beginners studying C programming language much.
