Purpose: The purpose of this study was to investigate the far-infrared emissivity of patented ocher quilt cotton fabrics and to investigate the microorganisms that survived the washing of cotton fabrics up to 20 times. Methods: A 16S rRNA assay was performed using a far-infrared radiometer and a single colony in which microorganisms grew in nutrient media. Results: The far-infrared emissivity of ocher quilt was 0.902 (90.2%) at 5~20 ㎛ at 40℃, and the radiation energy was 3.63 × 10² w/m². The number of viable cells was 2.0 × 10² cells/ml in ocher duvet cotton fabric, and no viable bacteria found in regular cotton fabric. The base sequence of 16S rRNA of B-2 strain isolated into single colonies was 1,419 bases, and the base sequence of strain A-4 was 1,284 bases. The base sequence of 16S rRNA of these two strains showed high homology with Bacillus spp. The B-2 bacteria showed high homology with 99.0% of the 16S rRNA sequence of B. aryabhattai EF114313 and 99.0% of the A-4 bacteria of B. bingmayongensis AKCS01000011. Consequently the colony strain B-2 finally identified as B. aryabhattai BJ-2 and A-4 as B. bingmayongensis BJ-4 strain. Concusions: Soil Bacillus strains survived in ocher quilt cotton fabric after 20 washing. The material can be useful because quilt cotton fabric emits a large amount of far-infrared and far-infrared radiation energy.

Faced with global agenda of greenhouse abatement program including regulations and $CO_2$ emission trading scheme, shipping companies are enforced to a high level of efficiency in fuel consumption. Accordingly shipbuilding companies worldwide are required to develop fuel-efficient ships which otherwise traditionally consume a great amount of fossil fuels. In this dissertation, relevant to the improvement of fuel efficiency for commercial ships, design methodology through the numerical simulations are intensively described. This work consists of derivation of effective hydrodynamic design practice based on the application of longitudinal grooves to effectively improve the pressure distribution around ship hull. The primary objective of the present study is to improve ship resistance performance using longitudinal grooves which originate from long strips on the abdomen of humpback whale. Several groove shapes have been extensively investigated and the proposed shape efficiently controlled the variation of pressure distributions acting on the hull surface.

Free Trade Agreement (FTA) between the Korea, of the one part, and the EU and its member states, of the other part, has been effective, as of 1 Jul 2011. EU enlarged its members up to 27 countries including Romania and Bulgaria in 2007, and stood up as the second largest trading partner to the Korea right after the China. FTA, generally, shows the several different figures according to the countries concerned on the agreement The EU has long history and cultural, educational assets. In addition to that, the EU also has economical, industrial bases. Therefore, the EU seeks fruitful profits utilizing its intellectual property rights. There are copyrights and related rights, trade marks, geographical indications, designs, and patents, etc. on the Chapter 10. intellectual property rights of the Korea EU FTA. Among them, the others except geographical indications seem to be somewhat the terms advantageous to the Korea. It is possible to ask further requirements to the Korea in the years to come because the EU member countries are very much interested in the practical profits of intellectual property rights. Thus, it would be essential tasks for us to review the intellectual property rights protection and features of the Korea EU FTA.

Conventional ORDBMS vendors provide extension mechanisms for adding user-defined types and functions to their own DBMSs. Here, the extension mechanisms are implemented using a high-level interface. We call this technique loose-coupling. The advantage of loose-coupling is that it is easy to implement. However, it is not preferable for implementing new data types and operations in large databases when high Performance is required. In this paper, we propose to use the notion of tight-coupling to satisfy this requirement. In tight-coupling, new data types and operations are integrated into the core of the DBMS engine. Thus, they are supported in a consistent manner with high performance. This tight-coupling architecture is being used to incorporate information retrieval(IR) features and spatial database features into the Odysseus/IR ORDBMS that has been under development at KAIST/AITrc. In this paper, we introduce Odysseus/IR and explain its tightly-coupled IR features (U.S. patented). We then demonstrate a web search engine that is capable of managing 20 million web pages in a non-parallel configuration using Odysseus/IR.

This study provides a definition of heat waves, which indicate the conditions of strong sultriness in summer, appropriate to Korea and intends to clarify long term(1973-2006) averaged spatial and temporal patterns of annual frequency of heat waves with respect to their intensity. Based on examination of the Korean mortality rate changes due to increase of apparent temperature under hot and humid summer conditions, three consecutive days with at least $32.5^{\circ}C,\;35.5^{\circ}C,\;38.5^{\circ}C,\;and\;41.5^{\circ}C$ of daily maximum Heat Index are defined as the Hot Spell(HS), the Heat Wave(HW), the Strong Heat Wave(SHW), and the Extreme Heat Wave(EHW), respectively. The annual frequency of all categories of heat waves is relatively low in high-elevated regions or on islands adjacent to seas. In contrast, the maximum annual frequency of heat waves during the study period as well as annual average frequency are highest in interior, low-elevated regions along major rivers in South Korea, particularly during the Changma Break period(between late July and mid-August). There is no obvious increasing or decreasing trend in the annual total frequency of all categories of heat waves for the study period However, the maximum annual frequencies of HS days at each weather station were recorded mainly in the 1970s, while most of maximum frequency records of both the HW and the SHW at individual weather stations were observed in the 1990s. It is also revealed that when heat waves occur in South Korea high humidity as well as high temperature contributes to increasing the heat wave intensity by $4.3-9.5^{\circ}C$. These results provide a useful basis to help develop a heat wave warning system appropriate to Korea.

This study was conducted to develop specific Single Nucleotide Polymorphism (SNP) markers to identify the genetic characteristics and breed of White Hanwoo (WH) using a molecular biological method. SNP genotyping was performed with an Illumina Bovine HD 777K SNP chip using DNA extracted from 48 Hanwoo and 22 WH. The minor allele frequency (MAF) difference of each SNP was calculated and the statistical significance (P-value) of the MAF difference was calculated through Fisher's Exact test (Genotype). SNPs with 100% difference in the MAF difference were selected based on marker selection criteria. The nine SNP markers with genetic differences were selected. The selected markers have different alleles as being Hanwoo- and WH- specific. Therefore, based on these results, it can be concluded that the Hanwoo and WH varieties can be clearly distinguished by using these SNPs. So, the patent of the WH breed identification markers was registered. WH is a breed that shows the characteristics of a Korean native species that is separate from the native Hanwoo. It is expected that genetic characteristics research on the WH can be used to identify the breed and as a knowledge base for enhancing the value of breeding stock.
