We described three cases of immediate reimplantation of a frozen-thawed autogenous mandible composed of a mixture of iliac bone, marrow, and particulate hydroxyapatite in tumors of the mandible. Acceptable outcomes were obtained in three patients who underwent immediate autogenous mandibular graft reconstruction. The conditions leading to successful outcome of the procedure are also discussed. Reimplantation of frozen autogenous lesioned mandible was performed in three patients with mandibular tumors. Two reimplanted grafts survived without complications following surgery. One case had postoperative infection that resolved with appropriate antibiotic treatment. There were no recurrences of the primary lesions. Satisfactory facial contour after surgery was achieved. These results are most promising, and we believe that, with further refinement, this technique will offer a new and acceptable modality for facial reconstruction in patients with cancer.

Tricholoma matsutake, an ectomycorrhiza that has mutual relationships with the rootlet of Pinus denisflora, forms a fruiting body that serves as a valuable food in Asia. However, the artificial culture of this fungus has not been successful. Soil fungi, including T. matsutake, coexist with many other microorganisms and plants; therefore, complex microbial communities have an influence on the fruiting body formation of T. matsutake. Here, we report on the structures of fungal communities associated with the fairy ring of T. matsutake through the pyrosequencing method. Soil samples were collected inside the fairy ring zone, in the fairy ring zone, and outside the fairy ring zone. A total of 37,125 sequencing reads were obtained and 728 to 1,962 operational taxonomic units (OTUs) were observed in the sampling zones. The fairy ring zone had the lowest OTUs and the lowest fungal diversity of all sampling zones. The number of OTUs and fungal taxa inside and outside the fairy ring zone was, respectively, about 2 times and 1.5 times higher than the fairy ring. Taxonomic analysis showed that each sampling zone has different fungal communities. In particular, out of 209 genera total, 6 genera in the fairy ring zone, such as Hemimycena, were uniquely present and 31 genera, such as Mycena, Boletopsis, and Repetophragma, were specifically absent. The results of metagenomic analysis based on the pyrosequencing indicate a decrease of fungal communities in the fairy ring zone and changes of fungal communities depending on the fairy ring growth of T. matsutake.

This study is investigated by experimental method and FEM about the effect of notch root radious(ρ) on the fracture of GFRP. The smaller ρ showed the fracture behavior which was mainly caused by the propagation of the stable crack, but the fracture behavior in the larger ρ was mainly caused by the spread of damage. The experimental value of the nominal stress could be estimated by FEM simulation and the load-displacement curve could also be drawn. According to the results simulated damage zone by FEM. as the ρ is smaller, the damage begin at low stress.

To investigate a horizontal windrose and the mixing height in Masan coastal area, a local atmospheric flow and the concentration of air pollutants were analyzed by abserved data from AWS, airsonde and air sampler. The land-sea breeze model and the ISCST2 model of U. S. EPA(Environmental Protection Agency) were used to predict the concentration of air pollutants such as SO2 and TSP. As a result, during spring the principal wind direction in the Masan region is mainly represented by windrose of the WNW and NW, which can be induced by land breeze and the SE and SSW of sea breeze even if weak wind speed. The mixing height during the measurement was marked with the range from 400 m(0900 LST) to 1450 m(1500 LST), and the height of an inverse layer was presented as the range from 30 m(2100 LST) to 150 m(0300 LST). It is very important to cosider the local wind field for the accurate diffusion and movement of air pollutants in coastal urban area. The atmospheric flow was simulated by the two-dimensional local wind model upon considering the orographic characteristics such as land-sea contrast, mountain valley and urban building. The result of air quality simulated by ISCST2 support that the dispersion pattern of the pollutants in that area was followed as local circulation system in coastal urban area.

The purpose of this paper is to evaluate the industrial importance of the environment industry in Pusan through regional input-output analysis. In the absence of the consensus on the definition and scope of environment industry and related data, this research inevitably focuses on environmental manufacturing industry. There are various techniques in converting the coefficients of a national table to those of a regional table. Among them, it is said that RAS procedure is most widely used method. So that method is adopted also in this research. The regional table can be obtained through 360 iterative adjustments of rows and columns by using GAUSS program. The empirical findings of this research show that among the manufacturing industries in Pusan environmental manufacturing industry has relatively strong backward linkage effect and the weakest forward linkage effect. From the above findings, if the demands for environmental industry in Pusan can be created by government policies, we can infer that the growth of other industries as well as environmental industry can be expected.

The purpose of this study is in developing locally-oriented teaching-learning materials to motivate students to effectively take part in activities using map and in improving the field work of social studies to plan a map learning and to give them the ability of practice. It represents the right order involved in teaching the activities using map after doing preceding learning : classroom, playground, and the environs of the school including to some learning methods such as a puzzle map, a correlative of learning. Field trip study planning and lesson-plan are designed in case of Sewage disposal plant, Duknam filtration plant, Bonchon industrial complex relating to field trip study. There are some effects expected which follow through this study. First, teachers are able to draw learner's interest in finding learning sources directly through the community where they live. Second, learners have active participation in class, motivation, drawing their interests through map learning by doing preceding study of learner-centered. Third, teachers can make use of it as useful tools to get high achievement goal with self-direct learning.

<P>Methylenetetrahydrofolate reductase (<I>MTHFR</I>), a critical enzyme in folate metabolism, plays an important role in DNA methylation. It has been suggested that abnormal DNA methylation contributes to the pathogenesis of schizophrenia and congenital anomalies. The previous findings regarding the genetic relationship between <I>MTHFR</I> and schizophrenia are controversial. This study investigated the association of the two functional polymorphisms of <I>MTHFR</I>, C677T and A1298C, with the risk for schizophrenia. Furthermore, we conducted an updated meta-analysis on the two polymorphisms. In addition, we investigated the relationship between the polymorphisms and minor physical anomaly (MPA), which may represent neurodevelopmental aberrations in 201 schizophrenia patients and 350 normal control subjects. There was no significant association between either of the two polymorphisms and the risk of schizophrenia (chi-square = 0.001, df = 1, <I>P</I> = 0.971 for C677T; chi-square = 1.319, df = 1, <I>P</I> = 0.251 for A1298C). However, in meta-analysis, the C677T polymorphism showed a significant association in the combined and Asian populations (OR = 1.13, <I>P</I> = 0.005; OR = 1.21, <I>P</I> = 0.011, respectively) but not in the Korean and Caucasian populations alone. Neither polymorphism was associated with MPAs measured by the Waldrop scale (chi-square = 2.513, df = 2, <I>P</I> = 0.285). In conclusion, the present findings suggest that in the Korean population, the <I>MTHFR</I> polymorphisms are unlikely to be associated with the risk for schizophrenia and neurodevelopmental abnormalities related to schizophrenia.</P>
