  • The sources of wayside noise for the high speed train are the aerodynamic noise, rolling noise and power unit noise. One of the best ways to control the wayside noise is to analysis the noise level. In this paper, we measure the wayside noise and the vibration of the rail/sleeper for Korean Train Express (KTX) and compare with the results for the conventional train. The measurement results for KTX show that the characteristics of the noise and vibration are different from the conventional train and the rolling noise and power unit noise are the major sources.

  • Recently, it was reported that certain polymorphisms in the growth hormone secretagogue receptor gene (GHSR) are associated with the growth of chickens. However, the correlation between GHSR polymorphisms and economic traits has not been investigated in Korean native chickens (KNCs). Therefore, the objective of this study was to confirm the suitability of the GHSR gene as a candidate for genomic selection and identify a genetic marker for KNCs. A total of 220 KNCs from six breeds raised at the National Institute of Animal Science were genotyped for the c.739+726 SNP in the GHSR gene using polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP), and the sequence for a subset of 30 birds was analyzed using direct sequencing. The association between the SNP genotypes and the economic traits of the KNCs was analyzed using the statistical package for the social science (SPSS) software program. The association analysis between the c.739+726T>C SNP and economic traits revealed that the SNP was significantly associated with body weight at 150 and 270 days (BW150 and BW270, respectively) in all KNCs (p<0.01), BW150 in KNC (Gary) (p<0.05), and egg production number in KNC (White, p<0.05). In addition, the SNPs discovered using direct sequencing (513A>G, 517A>T) had a significant effect on the body weight and egg production traits (p<0.05). In conclusion, these results might be useful as a basis for studies on the improvement of KNC breeds. Furthermore, these results suggest that the SNPs (c.739+726T>C, 513A>G, and 517A>T) located in the GHSR gene could be useful molecular genetic markers for KNCs.

  • This study was carried out to analyze the amount of telomeres and telomerase activity of several chicken cells. Telomere quantity and telomerase activity were analyzed during organ development, growth and aging in embryonic and adults chicken. Analyzed cells were whole embryos and the cells from brain, heart, liver, kidney, lymphocytes and germinal tissues in Korean Native Chicken. The amount of telomeric DNA was analyzed by quantitative fluorescence in situ hybridization (Q-FISH) techniques using a chicken telomere repeat probe. Telomerase activity was performed by Telomeric Repeat Amplification Protocol (TRAP) assay. In results, telomerase activity was highly detectable in early embryonic cells, germinal cells and kidney cells. Whereas the cells from brain, heart, and liver had gradually down-regulated pattern of telomerase activity. Analyzing the telomere quantities on chicken cells, the amount of telomeric DNA of most chicken cells gradually decreased as growth. From these results, the amount of telomeric DNA was directly affected by telomerase activity. Consequently the telomere quantity and telomerase activity are closely relate to cell differentiation and tissue specificity during developmental and growing stages.

  • We investigated possible therapeutic approaches to treat contagious naturally occurring ecthyma in Korean native goats in the Gongju area of Korea. Contagious ecthyma was found in 130 of 150 Korean native goats studied. Sixteen goats, ranged from 2 months to 2.5 years old, were selected for further experiments. The goats were divided into a control group, an ozonated oil group, and an ozonated water group consisting of 5, 5, and 6 goats, respectively. The control animals were not treated during the experimental period. The ozonated oil group was treated with ozonated oil, made by bubbling 200 ppm ozone gas into the oil, dally for 2 weeks. The remaining group of animals were given ozonated drinking water (0.1 ppm) ad libitum for 2 weeks. The ozonated oil treated group (4/5, 80%) had the highest therapeutic rate. The ozonated water group (4/6, 66.7%) had the second highest therapeutic rate, followed by the control group (1/5, 20%). Based on these results, a secondary experiment was performed that included a total of 121 Korean native goats with contagious ecthyma. Ozonated oil was applied daily for 30 days. All of the lesions on the goats with contagious ecthyma were completely cured by application of the ozonated oil. We concluded that ozone therapy was an effective treatment for contagious ecthyma in goats

  • The traditional market is foremost a regionally positioned place, wherein the market directly represents regional and cultural centered traits while it plays an important role in the circulation of facilities through reciprocal, informative and cultural exchanges while sewing to form local communities. The traditional market in Korea is one of representative retail businesses and premodern marketing techniques by family owned business of less than five members such as product management, purchase method, and marketing patterns etc. Since the 1990s, the appearance of new circulation-type businesses and large discount convenience stores escalated the loss of traditional competitiveness, increased the living standard of customers, changed purchasing patterns, and expanded the ubiquity of the Internet. All of these changes in external circulation circumstances have led the traditional markets to lose their place in the economy. The traditional market should revive on a regional site basis through the formation of a community of regional neighbors and through knowledge-sharing that leads to the creation of wealth. For the purpose of creating a wealth in a place, the following components are necessary: 1) a facility suitable for the spatial place of the present, 2)trust built through exchanges within the changing market environment, which would simultaneously satisfy customer's desires, 3) international bench marking on cases such as regionally centered TCM (England), BID (USA), and TMO (Japan) so that the market unit of store placement transfers from a spot policy to a line policy, 4)conversion of communicative conception through a surface policy approach centered around a macro-region perspective. The budget of the traditional market funding policy was operational between 2001 and 2004, serving as a counter move to solve the problem of the old traditional market through government intervention in regional economies to promote national economic strength. This national treasury funding project was centered on environmental improvement, research corps, and business modernization through the expenditure of 3,853 hundred million won (Korean currency). However, the effectiveness of this project has yet to be to proven through investigation. Furthermore, in promoting this funding support project, a lack of professionalism among merchants in the market led to constant limitations in comprehensive striving strategies, reduced capabilities in middle-and long-term plan setup, and created reductions in voluntary merchant agreement solutions. The traditional market should go beyond mere physical place and ordinary products creative site strategies employing the communicative approach must accompany these strategies to make the market a new regional and spatial living place. Thus, regarding recent paradigm changes and the introduction of region-based site functions into the traditional market, acquiring a conversion of direction into the newly developed project is essential to reinvestigate the traditional market composed of cultural and economic meanings, for the purpose of the research. Excavating social policy demands through the comparative analysis of domestic and international cases as well as innovative and expert management leadership development for NPO or NGO civil entrepreneurs through advanced case research on present promotion methods is extremely important. Discovering the seeds of the cultural contents industry cored around regional resource usages, commercializing regionally reknowned products, and constructing complex cultural living places for regional networks are especially important. In order to accelerate these solutions, a comprehensive and systemized approach research operated within a mentor academy system is required, as research will reveal distinctive traits of the traditional market in the aging society.

  • The perception of Korean housewives was investigated on commercial Korean basic side dishes. The questionnaires were distributed to 464 housewives in Busan area. According to the survey, the housewives preferred discount stores (44.1%) to purchase basic side dishes. The reasons for purchasing them were convenience (54.6%) and readiness in small amount (23.1%). The housewives had high perception scores on saying cooking time (4.90/5.00), the possibility of purchasing when they need (3.93/5.00), and convenient use (3.85/5.00). However, they doubted the propriety of making use of chemical seasoning (2.15/5.00), the original place of raw food materials (2.21/5.00), and shelf life control (2.44/5.00). The satisfaction scores on the commercial basic side dishes were 3.06/5.00 in braised perilla leaves, 2.98/5.00 in braised soybean, 2.96/5.00 in pickled garlic, and 2.96/5.00 in stir-fried/muchim dried fish. The priorities on the improvement demand for the basic side dishes were appeared in order of the sanitary preparation, the consistent tastes, the proper amounts of chemical seasonings, and sanitary distribution systems.
