Species identification using DNA sequences is the basis for DNA taxonomy. In this study, we sequenced the ribosomal large-subunit RNA gene sequences (3,037-3,061 bp) in length of 13 Chinese Theileria stocks that were infective to cattle and sheep. The complete 28S rRNA gene is relatively difficult to amplify and its conserved region is not important for phylogenetic study. Therefore, we selected the D2-D3 region from the complete 28S rRNA sequences for phylogenetic analysis. Our analyses of 28S rRNA gene sequences showed that the 28S rRNA was useful as a phylogenetic marker for analyzing the relationships among Theileria spp. in ruminants. In addition, the D2-D3 region was a short segment that could be used instead of the whole 28S rRNA sequence during the phylogenetic analysis of Theileria, and it may be an ideal DNA barcode.

In recent days, the accidents have happened at experimental laboratories in universities or institutes. In order to improve safety assurance of workers in laboratories, it is required to carry out systematic study concerned with evaluation of safety and health level. The safety and health inspection checklists were developed and conducted the case study. The case study was carried out laboratory safety inspection with 5 inspectors by the checklists to become aware of safety and health level. From the evaluation results of the inspection, we could be made quantification of laboratory through evaluation of safety and health level in laboratory. It was found that was recognized present states of the laboratory and established a plan for improvements in laboratory safety facilities from the case study. The safety inspection checklists can be used as basic data to establish evaluation criteria of safety and health level.

In a previous study, the potential of damping suspension bridges with active stay cables has been evaluated on a numerical model of a suspension bridge, and demonstrated experimentally on a laboratory mockup. In this paper, we extend our study to explore two different configurations of the active stay-cables: one classical configuration, corresponding to attaching the active stay-cables between the top of the pylons and the deck (configuration I) and, another configuration, consisting of attaching the stay-cables between the base of the pylons and the catenary (configuration II). The analysis confirmed that both configurations are effective with a slight superiority of the second configuration. The study is conducted numerically and experimentally on a suspension bridge mock-up, by considering two types of active stay-cables. The experimental results confirmed the numerical predictions, and demonstrated the effectiveness of the second configuration.

Purpose: As the structure of the disease has been changed and the infectious disease has been increased, the demand for diagnostic examination has been increasing. So, the department of laboratory medicine in hospital has playing the important role accounting for about nineteen percent of total medical expenses in korea. This study is to investigate the laboratory function and spatial composition of the department and figure out the space area and space organization. Methods: Explore the literature review to identify the laboratory function. Limit to five cases of tertiary level general hospital having about a thousand bed and analyze the space layout and floor area to confirm the spatial composition. Classify the exam function and check the spatial composition and spatial organization. Results: This study allows 5 conclusions to be summarized. Laboratory medicine divided into nine part in regulation, but in space allocated into core lab, emergency lab and six part lab. Total laboratory area is $2,036m^2$ in average, and is composited with 60% for lab, 17% for office and 20% for public. Lab area per a bed presents $1.88m^2$. Microbiolgy and molecular lab area are getting large. Laboratory space organized into the four zone, like an entrance zone, core zone, rear zone and peripheral zone. Emergency and transfusion lab are allocated in entrance zone, hematology chemistry and immunology in core lab, microbiology and molecular lab in rear, support offices in peripheral zone. The most important point was to check the spatial composition of the Laboratory Medicine according to the inspection function. Implications: This study can be used as a useful data in planning and designing a Laboratory Medicine Department.

Twenty Artemisia species are distributed in South Korea and rich in terpenoids. Artemisia rubripes (Compositae) has been used as a Korean traditional medicine for stomachache. vomiting. diarrhea and hemostatic agent. The antimutagenic effect and essential oils of Artemisia rubripes were reported, but phytochemical study has not been fully investigated. As part of our systematic study on the terpene constituents of Artemisia species. we have investigated A. rubripes (1 kg) collected at Dae-Kwan ryung. Gangwon Province on Aug. 1997. (omitted)

Diabetes mellitus (DM) leads to a variety of complications and thus we have retrospectively studied to investigate problems of nerve conduction velocity (NCV) study and the heart in the patients with type-II DM. Blood glucose and blood pressure levels were higher in DM group than in Non-DM group. We found that several latencies were delayed in motor conduction study of upper (median and ulnar nerve) and lower extremities (peroneal and tibial nerve), whereas amplitudes and NCVs were decreased in DM group compared with Non-DM group. Latencies of sensory conduction study in upper and lower extremities (sural nerve) were delayed, while amplitudes and NCVs were lower in DM group than in Non-DM group. Abnormal percent of the electrocardiogram was higher in DM group than in Non-DM group. This retrospective study suggests that type-II DM can cause a damage effect on the peripheral nerve and the heart function.

The purpose of this study is comprehension for relationships between job stress and mental health for dental technicians in performing their duties. and this study can make use of opportunity of accumulation of data on dental technician's health care and work environment in future. Job stress for dental technicians served in general hospital dental laboratory were more highly effected than in local dental laboratory. and this result was statistically reliable. There were no meaningful differences in mental health between dental technician in dental laboratory in dental climic dental laboratory and commercial dental laboratory. and this result was not statistically reliable. The analysis of this study could be used by preliminary data to further research of relationships between job stress and mental health for dental technicians in the future. This study was made progress partially under limited members of dental technician in Seoul. so future studies are suggested that the more advanced total figure study for whole dental technicians in Korea.
