  • To evaluate the genetic diversity and structure of the South Korean soybean population, 233 landraces collected in various regions of the country were surveyed for 15 allozyme loci and one protein locus. The South Korean population was fixed or nearly fixed at seven of the 16 loci tested. The number of alleles per locus was 2.06 and Nei’s gene diversity was 0.194. These values were lower than the values for the same 16 loci previously reported for the Japanese and Chinese populations. The differences among eight regional groups were not so marked, with only 7.2% of the total variation arising from regional differentiation. Three southern regional groups (Chollabuk-do, Chollanam-do and Kyong-sangnam-do) exhibited a relatively high variability because of frequent occurrence of alleles characteristic of the Japanese population. A marked difference was found in allelic frequencies at the Dial locus between large-seeded landraces and small-seeded ones, suggesting that the latter, which are used mainly for bean sprouts, had been established independently of the former, which are used mostly for soy sauce and cooking with rice. Not only the region but also the usage as food materials should therefore be taken into consideration in designing an efficient collection and preservation method for the Korean soybean landraces.

  • Objectives: We carried out an observational study of the effects of Nei Guan (P6) and Gong Sun (SP4) acupuncture for the treatment of CINV, preparing for further randomized controlled trial study. This is a case series to explore the changes in the incidence of CINV by acupuncture. Methods: Patients reported a Rhodex index indicating the severity of nausea and vomiting and loss of appetite, before acupuncture, after acupuncture and 1-week follow-up examination. Twelve patients with CINV participated in this study. We included patients receiving chemotherapeutic agents that might induce moderate or severe nausea and vomiting. We conducted 5 treatment sessions with P6 and SP4 acupuncture over the course of 5 days. Results: The median Rhodex score were decreased in 5 patients over time, while we observed loss of appetite of 6 patients were improved over time. During the study, the mean of Rhodex of total patients revealed a decrease of Day 1, Day 7, Day 14; 0.74, 0.68, 0.38, respectively, while the mean of loss of appetite showed a decrease of Day 1, Day 7, Day 14; 5.25, 4.08, 4.00, respectively. Conclusions: The study gives a preliminary data that manual acupuncture of P6 and SP4 may reduce the severity of CINV and loss of appetite, and justifies further study.

  • To investigate the genetic relationships among various cattle breeds, bovine mtDNA D-loop region was used in 411 animals of 18 cattle breeds, including 8 Asian Bos taurus, 7 European Bos taurus, 1 Asian Bos indicus, and 2 African Bos indicus. The size of amplified PCR products from mtDNA D-loop region was 964 bp and the products were digested by 15 different restriction enzymes. Two different band patterns were identified in eight restriction enzymes (BstXI, Hae III, Msp I, Apa I, Taq I, Alu I, BamH I, EcoN I) and the rest of restriction enzymes showed more than 3 different band patterns among which Apo I and MspR9 resulted in 7 different restriction patterns. The genotypes, number of haplotype, effective number of haplotype, and degree of heterozygosity were analyzed. Based on all the PCR-RFLP data, different haplotypes were constructed and analyzed for calculating genetic distances between these breeds using Nei's unbiased method and constructing a phylogenetic tree.

  • Background and Aim : As one of the World Cultural Heritage, Joseonwangjosillok is a history book including general state affair, social affair, economy, astronomical and atmospheric phenomena, art, music, eat. as well as the very private life of the king. With Joseonwangjosillok, we will look into health and death of the king and apply it to the regimen and recommended life-style of the aged. Materials and Method : With the archive of Joseonwangjosillok and medical text books such as Donguibogam Huang Di Nei Jing as reference, we tried to inquire the work and life of the kings of the Joseon dynasty, find connection with the regimen recommended life-style, and suggest medical guidelines for the aged as geriatric society is coming. Result : The Kings of the Joseon dynasty had omnipotent power, so that they lived quite much better lift than common people. But their average lifetime is estimated to be no better than that of ethers. Probably overwork, mental stress, rich fatty diet and lack of exercise took healthy life from them. Conclusion : Even if they had unlimited power, the state-of-the-art medical treatment hardly helped the Kings live better and longer life than common people. To keep and promote healthy lift for the aged, they need moderate exercise, appropriate rest, balanced diet, seen dissolving with reasonable environment.

  • With the on-going wireless access technologies, the Internet has become accessible anytime anywhere. In wireless networks, link errors significantly degrade the performance of the transmission control protocol (TCP). To cope with this issue, this paper improves the recently-proposed terrestrial REFWA (T-REFWA) scheme by adding a new error recovery mechanism to its original design. In the T-REFWA scheme, senders are acknowledged with appropriate sending rates at which an efficient and fair utilization of network resources can be achieved. As the feedback values are computed independently of link errors, senders can keep transmitting data at high rates even in case of link error occurrences. Using this feature, the proposed error recovery mechanism can achieve high throughput in environments with high bit error rates. The throughput is further improved by disabling the exponential back-off algorithm of TCP so that long idle times are avoided in case of link errors. We show through simulations that the proposed method improves TCP performance in high bit error rates. Compared with several TCP variants, the proposed error recovery scheme exhibits higher link utilization and guarantees system fairness for different bit error rates.

  • TEvaporator is key component in food, seawater distillation and waste water treatment system, which is basically to concentrate the raw liquid by evaporating the pure water under vacuum condition. The liquid concentration is performed through the membrane, electro-dialysis and evaporation. In this study, only the evaporating type was treated for evaluating the economic analysis with the various operating conditions. The results of this study showed that the performance of the OT-MSF desalination system is increased with decreasing the temperature difference between the neighboring evaporators, which means that the number of evaporators is increased, under the determined design conditions.

  • Nine microsatellite loci were analyzed in 84 random individuals to characterize the genetic variability of three domestic goat breeds found in Korea and China: Korean goat, Chinese goat and Saanen. Allele diversity, heterozygosity, polymorphism information content, F-statistics, indirect estimates of gene flow (Nm) and Nei's standard distances were calculated. Based on the expected mean heterozygosity, the lowest genetic diversity was exhibited in Korean goat ($H_E$=0.381), and the highest in Chinese goat ($H_E$=0.669). After corrections for multiple significance tests, deviations from Hardy-Weinberg equilibrium were statistically significant over all populations and loci, reflecting the deficiencies of heterozygotes (global $F_{IS}$=0.053). Based on pairwise FST and Nm between different breeds, there was a great genetic differentiation between Korean goat and the other two breeds, indicating that these breeds have been genetically subdivided. Similarly, individual clustering based on the proportion of shared alleles showed that Korean goat individuals formed a single cluster separated from the other two goat breeds.

  • Nine brand populations of Hanwoo cattle were characterized using 11 microsatellite DNA markers. The studied populations were: Ansung, Yangpyang, DaeGwanryeng, Palkongsangkangwoo, Hoengseong, Jangsu, Sumjinkang, Hadong, Nam-hae. The observed heterozygosity, expected heterozygosity, and polymorphism information content were calculated. Allele frequencies were calculated and used for the characterization of each brand population and to study their genetic relationships. Genetic distances were estimated using Nei's DA genetic distance and the resultant DA matrix was used in the construction of phylogenetic trees. The NJ tree showed that Ansung and Yangpyang, Sumjinkang and Jangsu, Namhae and Ha-Dong are closely related and are considered to have undergone genetic exchange within the same locale. This study will contribute to the local Hanwoo brand industry.
