  • Antler has been used as one of the important traditional oriental medicines for many years. It contains many biochemical components including lipids, peptides, carbohydrates, and inorganic substances. The various biological activities of antler are being considered owing to such biochemical components. The purpose of this research is to compare the biochemical components of antlers after treatment of three different kinds of fodder. They are mulberry (group A), Lycii Fructus (group B) and the complex of herbs (group C). The chemical composition of each antler was determined in three sections (top, middle, and bottom) and compared with those of the control. The contents of sialic acid, uronic acid and glycosaminoglycans increased in the top antlers of the group B. Total lipids content increased in the top antlers of all groups (A, B, and C). The concentration of inorganic ions (Ca, Mg, and P) decreased in all groups. Fattyacid composition was also analyzed by GC-MS and expressed as percentage of total fatty acid concentration. The content of palmitic acid decreased in all groups. The content of 2-hydrox-yhexadecanoic acid, which has not been reported in aster, increased in the top antlers of all groups. These results suggest that the treatment of special fodder may affect the composition of the biochemical components of antlers.

  • In this study, a computer program to predict the behavior of laterally loaded single pile and pile groups was developed by using a beam-column analysis in which the soils are modeled as nonlinear springs by a family of p-y curves for subgrade modulus. The special attention was given to the lateral displacement of a single pile and pile groups due to the soil condition and the cap rigidity. The analysis considering group effect was carried out for $2{\times}2$ and $3{\times}3$ pile groups with the pile spacing 3.0B, 4.0B and 5.0B. Based on the results obtained, it is found that the overall distributions of deflection, slope, moment, and shear force in a single pile give a reasonable results irrespective of cap connectivity conditions. It is also found that even though there are some deviations in deflection prediction compared with the observed ones, the prediction by present analysis simulates much better the general trend observed by the centrifuge tests than the numerical solution predicted by PIGLET.

  • Even though the rate of infection of HIV is very low compared to other countries, data show a steady rise in HIV infection rates among young people in South Korea. A peer education program was provided to prevent the incidence of AIDS in young people. The program used peer leaders to provide AIDS related information and counseling for middle school students. Peer leaders received special training in AIDS related education and counseling to assist their friends. Peer leaders worked with their mends in one-to-one or small group settings. A pretest-posttest control design (six months after intervention) was used to evaluate the effects of the peer education program for prevention of AIDS. A post-intervention survey found that do you mean six months after the program or after six months of programs of peer program activities, the experimental groups(groups with peer educators) showed better knowledge, more positive attitudes, and less sexual activity when compared to control groups of non-participants(groups without peer educators). Peer leaders showed significant gains in knowledge about HIV transmission, more positive attitudes and self-efficacy not to engage in high-risk behaviors. Peer education was an effective tool for increasing knowledge, improving attitudes and self-efficacy, and encouraging appropriate behavior change.

  • This study about the Zoot Style is the first part of a series of research, which is to examine various subcultural styles in 1900s. The main concern of this research is to investigate the origin of a style, the way how it developed, and the reason it appealed to people. Subculture is a marginallized culture which the subordinal groups in the social structure developed as a means of reaction against the dominant groups of a society. The clothes and decorations of these groups can be regarded as the central expressions of exclusiveness, loyalty and identities for their groups. In 1990s, the distinction between the subcultural style and high fashion tend to be blurred, because it has gained more influence on the high fashion. Zoot Suit, adopted and diffused by Cap Calloway in 1940s, is the code of a subculture formed by a special race, class, space, gender, and generation identities. It develops as a reaction, and consequently reflects the struggles against the dominant culture: it is to refuse, appreciate and ridicule the dominant style. The Zoot Style had a great influence both in Paris and Cuba: the Zazous Style in Paris and the Caribbean Style of Cuba are the subcultural styles branched from the Zoot Style.

  • Objective: This study aimed to evaluate the volume, amount, and localization of root resorption in the maxillary first premolars using micro-computed tomography (micro-CT) after expansion with four different rapid maxillary expansion (RME) appliances. Methods: In total, 20 patients who required RME and extraction of the maxillary first premolars were recruited for this study. The patients were divided into four groups according to the appliance used: mini-implant-supported hybrid RME appliance, hyrax RME appliance, acrylic-bonded RME appliance, and full-coverage RME appliance. The same activation protocol (one activation daily) was implemented in all groups. For each group, the left and right maxillary first premolars were scanned using micro-CT, and each root were divided into six regions. Resorption craters in the six regions were analyzed using special CTAn software for direct volumetric measurements. Data were statistically analyzed using Kruskal-Wallis one-way analysis of variance and Mann-Whitney U test with Bonferroni adjustment. Results: The hybrid expansion appliance resulted in the lowest volume of root resorption and the smallest number of craters (p < 0.001). In terms of overall root resorption, no significant difference was found among the other groups (p > 0.05). Resorption was greater on the buccal surface than on the lingual surface in all groups except the hybrid appliance group (p < 0.05). Conclusions: The findings of this study suggest that all expansion appliances cause root resorption, with resorption craters generally concentrated on the buccal surface. However, the mini-implant-supported hybrid RME appliance causes lesser root resorption than do other conventional appliances.

  • Background: Lead (Pb) exposure in shooting ranges has been reduced by various measures such as jacketed ammunition and lead-free primers. Nevertheless, this may lead to exposure to other metals, potentially resulting in adverse health effects. Methods: In a cross-sectional study, 35 subjects from seven different shooting ranges were studied: four shooting instructors, 10 police officers, 15 Special Forces, and six maintenance staff members. Metals and metalloids were determined in blood and urine by inductively coupled plasma-mass spectrometry. Results: The concentrations of most elements did not differ significantly between groups or compared to reference values, except for Sb and Pt in urine and Pb in blood. Mean values for Sb were considerably higher in urine from the Special Forces ($0.34{\mu}g/L$), the maintenance staff ($0.13{\mu}g/L$), and shooting instructors ($0.32{\mu}g/L$) compared to the police officers before shooting ($0.06{\mu}g/L$) and a Belgian reference value ($0.04{\mu}g/L$). For Pt, the Special Forces showed higher mean urinary concentrations ($0.078{\mu}g/L$) compared to a Belgian reference value (<$0.061{\mu}g/L$). Mean values for blood lead were markedly higher in the Special Forces ($3.9{\mu}g/dL$), maintenance staff ($5.7{\mu}g/dL$), and instructors ($11.7{\mu}g/dL$) compared to police officers ($1.4{\mu}g/dL$). One instructor exceeded the biological exposure index for blood Pb ($38.8{\mu}g/dL$). Conclusion: Since both Pb and Sb were found to be higher in shooting range employees, especially among frequent shooters, it is advisable to provide appropriate protective equipment, education, and medical follow-up for shooting range personnel in addition to careful choice of ammunition.
