After the IMF jurisdiction period, the Korean economy experienced a venture boom. Korean venture enterprises had been recognized that high profitable and high technology capacity based. These ventures also have contributed to national added value tolerably. In particular, Korean information technology (IT) venture companies got away the order of economy concentrated big companies, which were taken the opportunity of new economy to make suggestion of the future courses and to open an e-Korea era. However, IT ventures firms or dotcom enterprises have had difficulties through sinking down their bubbles and slumping technology sector from the first half of the 2000. In consideration of Korea IT venture companies' conditions, Korean government introduce new national vision in order to go ahead of intelligence based society form knowledge based. Korea is planning new investment to meet with the challenge of globalization proactively by national band named u-Korea. As following a step in IT infrastructure, it will give Korean IT ventures new demand creative technologies and services by new technological windows of opportunity. This situation is expected that will become an economic take-off. This paper will look for the way to stimulate Korean IT ventures' competence and present new frontier of IT ventures turnaround.

As foundation wear, underwear is the starting point where a woman shapes her figure and constructs a female identity. In the late twentieth century, the use of underwear as outerwear was extensively adapted, so underwear as outerwear is the latest thing today. Based on literature review, this study aimed to examine how underwear was adopted for use as outerwear extensively in the late twentieth century. The result of this study can be summarized as follows. First, originally there was no border between underwear and outerwear at the start. With the change of female social and political status, the function of underwear and its design has been changed diversely. Also, its revealing and decoration has been linked with female sexual attraction. Second, by some precursor fashion designers such as Vivienne Westwood and Jean Paul Gaultier, underwear was redefined as outerwear with erotic but powerful meaning in the Twentieth century. Their idea had an enormous influence on contemporary fashion culture, and consequently has become popularized like lingerie look today. Third, the change of female social status led a big change in view on the female sexuality and the ideas of femininity in fashion culture in the Twentieth century. Dressed by Gaultier, Madonna's performance wearing corset costume played a role in redefining contemporary femininity in relation to sexuality and power, even though it is still under the controversy.

The first purpose of this study was to compare the fashion zones and fashion brands on the floors in small and medium volume department store with those of big department stores within adjacent trading area. The second purpose was to find out similarity and differentiation of near-by department stores. The third one was to propose the future fashion marketing strategies of the department stores. The methods used were references, internet, field observation, and interview in 2002. Eight department stores within adjacent trading area were classified and analysed In "Gangnam division", "Seocho division＇. and "Youngdeungpo division". The results were as follows : Firstly, there was a low relationship between the degrees of brand equalization of each department store in the "Gangnam, Seocho. and Youngdeungpo division". Secondly, there was an alteration on the floor layout of each department store. It was layed out in a way that allowed for customers, who wanted to just purchase specific items, to go upstairs and look around several stores, which allowed for not only rise in the amount of sales but also offer the convenience of one stop shopping for the customers. Thirdly I proposed several marketing strategies such as lifestyle marketing, relationship marketing, and compile marketing which solves everyday life agenda. I also proposed the solution selling education to develop service education of salesperson. I finally proposed the overriding priority policy by sales record of each store.licy by sales record of each store.

Recent university students are under a lot of stresses due to academic performance, employment, and anxiety about the future in the fierce competition. Mobile games can be used as a plan which can reduce the stresses of these students. However, if they play too long the games, it will cause another big problems. In this paper, we experimented to look for the best mobile game time to alleviate the stresses of university students as follows. First, we chose 16 people which have more stress load than the average student through stress tests by the basic diagnosis questionnaire. Second, we did total eight experiments on the stresses of the subjects in the study. That is, the experiment was carried out once before the test, 6 times for the mobile game (60 minutes), and once before the experiment. Third, we did T-test and multivariate analysis on the collecting data. As a result, it is proved that the mobile game for about 20 minutes could derive the effect on reducing stresses.

This study is intended to look into the effect of construction safety supervision system on risk control and reduction. To achieve this, a survey was carried out to 114 companies in construction, ordering, contract and management. The overall findings were as follows. The effect of construction safety supervision system on risk control and reduction showed that factors of supervision system, supervision cost and supervision method had a positive effect on risk control and reduction. And their perception of the introduction of safety supervision system in construction sites according to process showed that there was a difference between them according to the field of ordering, contract and supervision. There was the biggest difference between owner and contractor in double supervision system, but no difference between them in the perception of risk reduction. These results show that all ordering, contract and supervision are positively needed for the introduction of construction safety supervision. This means that there is a difference between owner and contractor in the perception of process according to system operation. All companies agree to system improvement by the settlement of safety supervision system for the prevention of safety accidents and safe construction, but the systematic complement of safety supervision is the burden of contractor. And there is a big difference between owner and contractor in the perception of responsibility and concern for cost burden.

Atomic Layer Deposition (ALD) has remarkably developed in semiconductor and nano-structure applications since early 1990. Now, the advantages of ALD process are well-known as controlling atomic-level-thickness, manipulating atomic-level-composition control, and depositing impurity-free films uniformly. These unique properties may accelerate ALD related industries and applications in various functional thin film markets. On the other hand, one of big markets, Display industry, just starts to look at the potential to adopt ALD functional films in emerging display applications, such as transparent and flexible displays. Unlike conventional ALD process strategies (good quality films and stable precursors at high deposition processes), recently major display industries have suggested the following requirements: large area equipment, reasonable throughput, low temperature process, and cost-effective functional precursors. In this talk, it will be mentioned some demands of display industries for applying ALD processes and/or functional films, in terms of emerging display technologies. In fact, the AMOLED (active matrix organic light emitting diode) Television markets are just starting at early 2013. There are a few possibilities and needs to be developing for AMOLED, Flexible and transparent Display markets. Moreover, some basic results will be shown to specify ALD display applications, including transparent conduction oxide, oxide semiconductor, passivation and barrier films.

About 12 rain gauge stations of Korea, annual maximum rainfall series of before and after 1980 whose durations are 1, 2, 3, 6, 12, 24, 48, 72 hours respectively were composed and statistical characteristics of those time series were calculated and probability rainfall were estimated by L-moment frequency analysis method and compared each other in order to investigate the recent quantitative rainfall variations. And also, distribution curves of each statistical variations for each duration were constructed by using Kigging method to look into spacial rainfall variation aspects. As a result, We could confirm recent rainfall increase in the South Korea. And spatial increase pattern of standard deviation and frequency rainfall appeared analogously each other. 1n the cases of comparatively short rainfall duration, we could see relatively low increase or decrease tendency in Chungchong Province, Cholla-bukdo, Cholla-namdo eastern part, Kyongsang-namdo western part area. While, variations happened great1y in seaside district of east coast, southwest seashore, Inchon area etc. In the cases of longer durations relatively low increase was showed in southern seashore such as Yeosoo area and as distance recedes from this area, showed gradually augmented tendency. The aspect of mean looks similar tendency of above except that the variation rate of almost seaside district are big in the case of shorter durations. In addition, rainfall increases of short durations which became the center of hydrologist and meteorologist are unconfirmed in this study.

Quantum information has passed the theoretical research period and has entered the realization step for its application to the information and communications technology (ICT) sector. Currently, quantum information has the advantage of being safer and faster than conventional digital computers. Thus, a lot of research is being done. The amount of big data that one needs to deal with is expected to grow exponentially. It is also a new business model that can change the landscape of the existing computing. Just as the IT sector has faced many challenges in the past, we need to be prepared for change brought about by Quantum. We would like to look at studies on quantum communication, quantum sensing, and quantum computing based on quantum information and see the technology levels of each country and company. Based on this, we present the vision and challenge for quantum information in the future. Our work is significant since the time for first-time study challengers is reduced by discussing the fundamentals of quantum information and summarizing the current situation.
