"Series A Crunch"problem has become worse off as funding gap between angel seed investment and traditional VC Series A investment is getting the larger due to big boom over early startup investment both in Korea and US. The strong needs for new concept of fund alternative such as bridge fund is outstanding to fill up the funding gap in the early stage of venture investment. This research is brought to define the concept of 'Series A Crunch' problem and to diagnose its causes, eventually, popping up 'the concept of Micro VC Fund' to come up with this problem in Korea. Also, this paper suggests the policy alternatives to introduce Mivro VC Fund and accommodate its successful performance.

This study intends to suggest production process of circular knitted jackets and dimensional change data of finished clothes after washing. the study provides pattern design method of circular knitted jackets by applying dimensional change. By doing so, the purpose of this study is to increase production efficiency through accurate order in consideration of loss amount of the fabrics in production. With the three fabric materials selected, this study investigated dimensional change of circular knitted jackets after sewing and washing by varying the parts to be attached to padding cloth and with or without inner lining. As for the fabric F-C (including the spandex, thicker and weightier than the other two fabrics), front width shrunk by 4.6%, which showed the biggest shrinkage among the jackets made of test fabrics. Then it suggested design methods of circular knitted jacket patterns to which dimensional change is applied according to materials, and analyzed the amount of fabric required for production by comparison of the materials. When using the fabric F-C without inner lining, there is big dimensional change and more than double amount of fabric is required. It is expected that the research results will be a basic data for pattern design and production process of circular knitted clothing.

High manganese steel was maintained stability of Non-Magnetics performance. Fatigue tests were carried out under constant stress amplitude, using a non-magnetic high manganese steel. The fatigue crack growth mechanism of the high manganese steel was clarified from results such as observation of crack growth path and fracture surface. The result of getting this study was shown as following: 1) Remarkably ${\Delta}Kth$ of the high manganese steel is big with about 3 times of the general steel product. 2) In the low ${\Delta}K$ value region, da/dN is dependent on Kmax, and in the high ${\Delta}K$ value region, it is dependent on ${\Delta}Keff$. The reason of this behavior is crack closure due to fracture surface roughness and fretting oxide. 3) It seems to ease the stress concentration of crack tip crack growth behavior in the ${\Delta}Kth$ vicinity by the generation of the secondary crack.

It should be unthinkable to not provide water at survival of any living things. Water is too a basic element for development for a country. Currently, the global market of mineral water is growing rapidly. This study, I conceptualized mineral water as bottled water. In particularly, bottled water has seen huge global growth for the last few years. The annual growth rate of the market in the period 2005-2009 was 5.9%. Following a surge in obesity and subsequent health and wellness trends, many consumers are switching from sugary soft drinks to healthier alternatives. Therefore, the global bottled water market is one area which has big potential for growth, but price competition is getting intensified among multi-national and domestic firms. Korean providers too are faced with strong competition in growing domestic market. The bottled water market has presence of multinational provider like Nestle, Danone and Coca-Cola, which collectively account for 35.1% of the world market share in 2009. On the basis of a market orientation approach, this article looks at changing environments in the world mineral water industry and attempts to describe foreign market entry strategy of the Korean mineral water industry. The market orientation provides strong norms for learning from customers and competitors, is instrumental in creating a superior value for buyers, innovating successfully, and generating excellent firm performance. So firms should consider a strategic planning in basis on market orientation before they enter foreign markets. Some discussions were made about managerial implications for Korean bottled water providers.

Recent advances in genome sequencing technologies have enabled humans to generate and investigate the genomes of wild species. This includes the big cat family, such as tigers, lions, and leopards. Adding the first high quality leopard genome, we have performed an in-depth comparative analysis to identify the genomic signatures in the evolution of felid to become the top predators on land. Our study focused on how the carnivore genomes, as compared to the omnivore or herbivore genomes, shared evolutionary adaptations in genes associated with nutrient metabolism, muscle strength, agility, and other traits responsible for hunting and meat digestion. We found genetic evidence that genomes represent what animals eat through modifying genes. Highly conserved genetically relevant regions were discovered in genomes at the family level. Also, the Felidae family genomes exhibited low levels of genetic diversity associated with decreased population sizes, presumably because of their strict diet, suggesting their vulnerability and critical conservation status. Our findings can be used for human health enhancement, since we share the same genes as cats with some variation. This is an example how wildlife genomes can be a critical resource for human evolution, providing key genetic marker information for disease treatment.

This study is on the children's clothing in Seoul Gyeonggi-do, Chungcheong-do and Gangwon-do between the $1920s{\sim}1950s$, by comparing positive data collected from pictures and literatures, remains and interviews. A baenaet jeogori was made of soft white cotton fabrics and was used as a charm when the baby had grown and had an test or a big occasion. A dureong chima and pungcha trousers were clothes for both boys and girls from their birth to the age of $4{\sim}5$ when they could have bowel movements by themselves. Occasions for celebrating a baby's growth were the one-hundredth day and the first birthday. In general, ordinary families had their babies' one-hundredth day in a simple way without special clothes. On the first birthday, however, even ordinary families prepared new clothes for their babies, and read their fortune and prayed for their well being and long life through events such as doljabi. In the age when medicine was poor and the infant mortality was high, the meaning of such a ceremony was to congratulate on the baby's safe growth through dangerous moments.

In this paper, we proposed quad variable rates ADPCM coding method and its implementation on C6000 DSP, which is modified from the standard ADPCM of ITU G.726 for speech quality improvement considering the environmental noise Four coding rates, 16Kbps, 24Kbps, 32Kbps and 40Kbps are used for speech window samples and the rate decision threshold is decided by the environmental noise level. The object of the proposed method is to reduce the coding rate while retaining the speech quality and the speech quality is considerably close to 40Kbps single rate coder with the coding rate close to 16Kbps single rate coder under the environmental noise. The environmental noise level affects the coding rate and the noise level is calculated per every speech window samples. At high noise level, more samples are coded at higher rates to enhance the quality, but at low noise level, only the big speech signals are coded at higher rates and more speech samples are coded at lower coding rates to reduce the coding rates. The influence of the noise on tile speech signal is considerably high for small signals and the small signal has the higher ZCR (zero crossing rate). The method is simulated in PC and to be implemented on C6000 floating point DSP board in real time operations.

대학에서는 매학기 개설된 수업에 대해 강의실 배정작업을 진행하고 있으며 대부분의 대학에서는 년4회(1 2학기, 여름, 겨울 계절학기) 수작업으로 반복적인 강의실 배정 작업을 수행하고 있다. 강의실 배정작업은 교수가 선호하는 강의실 또는 교과목특성(실험과목 및 대형 강의)이 반영된 강의실 등 다양한 조건에 의해 강의실을 배정하고 있으며 수작업으로 일일이 강의실을 배정 하는 데에는 상당한 시간이 소요되고 있다. 몇몇 대학에서는 강의실 배정작업을 개선하기 위해 교수 및 강의실의 특성을 고려한 강의실 자동 배정 시스템을 구축을 시도 하였으나, 많은 변수로 인해 여전히 수작업으로 강의실을 배정하고 있다. 이에 본 연구에서는 강의실 자동 배정 시스템을 구축하기 위한 방법으로 최근 3년간 기 배정된 강의실 빅 데이터 자료를 기반으로 작성된 강의실 자동 배정 알고리즘을 제시하고 실적용한 고려대학교 시스템 구축 사례를 살펴보고자 한다.

Password, a traditional user confirmation method that is used for more than 100 years, has become useless as a lot of transactions are dealt by indirect contacts. As a result, an alternative for password is required now. In this paper, we propose a novel confirmation method, which is called Brain-Key. It uses an indirect password input method. It reduces the risks due to hacking, and prevents a big credit accident because it prevents passwords to be reused. Our proposed model has general applicability so that it can be applied in domestic market as well as international markets. This research may provide solutions for the security problems in the electronic commerce.
