  • In order to elucidate the pathogenesis of cleft lip and palate, first of all, it is necessary to understand the developmental mechanisms of growth factors and extracellular matrix proteins in the tissues of cleft lip and palate. We have performed immunohistochemical studies on human cleft lip and palate tissues to elucidate the pathogenetic implications of cleft lip and palate. 16 specimens from postnatal human cleft lip and palate subjects and 17 specimens from autopsy of prenatal human cleft lip and palate were fixed in 10% buffered formalin, embedded in paraffin. The sections were routinely stained by hematoxylin and eosin, also stained by PAS, and followed by immunohistochemical stainings using the antiseras of growth factors and extracellular matrix proteins such as PCNA, S-100, c-erb-B2, MMP-3, MMP-10, HSP-70, transglutaninase-C, E-cadherin, VEGF, vWF. Both the prenatal and postnatal specimens of cleft lip and palate showed dysplastic proliferation of the basal cell layer, increased infiltration of melanocytes into mucosal epithelium, sebaceous gland hyperplasia ingrowing into the muscular tissue of lip and palate, and fatty infiltration into the submucosal deep connective tissue. The strong reactions of MMP-3 and HSP-70 were detected in the tissues of cleft lip and palate, especially increased in degenerating muscle bundles, while the immunostainings of PCNA and c-erb-B2 were weakly positive in the tissues of cleft lip and palate. These data suggest that the retrogressive tissue degeneration around the cleft areas persistently exist during the prenatal and postnatal period after cleft formation, and the sebaceous gland hyperplasia and fatty infiltration with the intense expression of MMP-3 and HSP-70 is closely related to the muscular degeneration around the cleft area.

  • The present research was focused to investigate the quality of non-polar SiC substrates grown by a conventional PVT method for optoelectronic applications. The half part of the PVT-grown 6H-SiC crystal boules was sliced along a-direction and m-direction to extensively analyze non-polar planes and then remaining part of that was sliced along the basal plane to produce wafers. The non-polar SiC m-plane and a-plane exhibited apparent peaks around 2 theta=$120^{\circ}$((3-300) plane) and 2 theta=$60^{\circ}$ ((11-20) plane), respectively. FWHM values of m-plane measured along a-direction and c-direction were 60 arc see and 57 arcsec respectively, a-plane measured along m-direction and c-direction were 41 arcsec and 51 arcsec respectively. The typical absorption spectra of SiC crystals indicated that each of SiC crystals were the 6H-SiC with fundamental absorption energy of about 3.04 eV. Non-polar planes contained no micropipe on etched surface. The carrier concentration and mobility of non-polar SiC wafers have estimated by Raman spectrum. It was observed that the carrier mobility is low in the area far from seed crystal with compared to other places.

  • In order to monitor the vegetation restoration in the evergreen broad-leaved forest, eighteen experimental plots including control plots were established at Wando Arboretum in 1996. Several treatments such as density control, selective cutting and warm temperate species planting were done in the experimental plots. Seven years after the restoration experiments, the important percentage of Quercus acuta showed a tendency to a higher increase in the experiment plots than control plots in Q. Acutu. Also the important percentage of Q. Acuta in Q. acute Carpinus tschonoskii community increased in the tree layer. Pinus densiflora community was increased highly in important percentage of Q. Acuta, As a whole, vegetation structure in the experiment plot showed successional stage to Q. Acutu community. In addition, important percentage of evergreen broad-leaved trees and shrubs and number of warm temperate species and basal area were increased in the experiment plots while the introduced evergreen broad-leaved trees were declined.

  • This study was conducted to distinguish adult morphology of the giant water bug (Lethocerus deyrollei) between over-wintered (OLD) and new-born (NEW) populations using materials collected from Gyodong island in Gyeonggi-do, Korea, as well as individuals reared in the laboratory (LAB population) as a control. As a result, no fundamental differences were found in external body structure between OLD, NEW, and LAB populations. However, marginal area of basal procoxa in ventral prothorax and jointed part of forefemur and foretibia were greatly worn in the OLD population. Mid-claws were shorter than 0.5 times the length of the 2nd mid-tarsus; the membranous margin of hemelytra was greatly worn; and hairs of the 5th abdominal tergum were greatly reduced in the OLD population.

  • Objectives : The aim of this research is to determine the effects of depression and anxiety symptoms of schizophrenic psychopathology on the HPA axis. Methods : Twenty patients with schizophrenia were included and divided into the medication non-exposed group(n = 10) and the medication exposed group(n = 10). Evaluated scales were the Positive and Negative Syndrome Scale(PANSS), Scale for the Assessment of Negative Symptoms(SANS), Scale for the Assessment of Positive Symptoms(SAPS), Hamilton Depression Inventory(HAM-D) and Hamilton Anxiety Inventory (HAM-A), and then the combined Dexamethasone/Corticotropin Releasing Hormone(DEX/CRH) test was conducted to determine the basal level, the peak level and the area under the curve(AUC) of cortisol and adrenocorticotropic hormone(ACTH). Results : When the correlations between each psychopathology and cortisol level or ACTH AUC value were analyzed, HAM-D showed a negative correlation, whereas HAM-A showed a positive correlation. Also, the non-depression group(HAM-D ${\leq}$ 18) showed higher cortisol and ACTH concentrations than the depression group(HAM-D > 18), and the anxiety group(HAM-A ${\geq}$ 14) showed significantly higher concentrations than the non-anxiety group(HAM-D < 14)(p < 0.05). Also, as for the comparison between the medication non-exposed group and the medication exposed group, the non-exposed group showed significantly higher cortisol and ACTH concentration than exposed group(p < 0.05). Conclusion : This study suggest that anxiety symptoms rather than depression symptoms are related to the increased activity of the HPA axis of schizophrenics.

  • Stem diameter variability is an essential inventory result that provides useful information in forest management decisions. Little has been done to explore the modelling potentials of standard deviation (SDD) and coefficient of variation (CVD) of diameter at breast height (dbh). This study, therefore, was aimed at developing and testing models for predicting SDD and CVD in stands of Pinus caribaea Morelet (pine) in south west Nigeria. Sixty temporary sample plots of size $20m{\times}20m$, ranging between 15 and 37 years were sampled, covering the entire range of pine in south west Nigeria. The dbh (cm), total and merchantable heights (m), number of stems and age of trees were measured within each plot. Basal area ($m^2$), site index (m), relative spacing and percentile positions of dbh at $24^{th}$, $63^{rd}$, $76^{th}$ and $93^{rd}$ (i.e. $P_{24}$, $P_{63}$, $P_{76}$ and $P_{93}$) were computed from measured variables for each plot. Linear mixed model (LMM) was used to test the effects of locations (fixed) and plots (random). Six candidate models (3 for SDD and 3 for CVD), using three categories of explanatory variables (i.e. (i) only stand size measures, (ii) distribution measures, and (iii) combination of i and ii). The best model was chosen based on smaller relative standard error (RSE), prediction residual sum of squares (PRESS), corrected Akaike Information Criterion ($AIC_c$) and larger coefficient of determination ($R^2$). The results of the LMM indicated that location and plot effects were not significant. The CVD and SDD models having only measures of percentiles (i.e. $P_{24}$ and $P_{93}$) as predictors produced better predictions than others. However, CVD model produced the overall best predictions, because of the lower RSE and stability in measuring variability across different stand developments. The results demonstrate the potentials of CVD in modelling stem diameter variability in relationship with percentiles variables.

  • The location of the style sac and morphology of the crystalline style were described morphologically in three bivalve species (Tegillarca granosa, Mytilus galloprovincialis and Saxidomus purpuratus) which inhabited in different area. The style sac of them was connected to the posterior stomach. There was the crystalline style in the style sac. The crystalline style of three species was long circular cone of translucent gelatin form, which was hard and elastic. There was a red-yellow and spiral filament inside the crystalline style of Tegillarca granosa and Mytilus galloprovincialis. A white and long tube was located from basal portion to the end of crystalline style in Saxidomus purpuratus. RLC (relative length of crystalline style) of Tegillarca granosa, Mytilus galloprovincialis and Saxidomus purpuratus was 47.69, 48.97, 64.20% and RWC (relative weight of crystalline style) was 0.54, 0.54, 0.39%, respectively.

  • Two newly naturalized species were recorded from Gangwon-do and Jeju-do. Among them, numerous populations of Hieracium caespitosum (Asteraceae) were found in 2006 along the road near the military area at, Mt. Dosolsan, Yanggu-gun, Gangwon-do. The other species, Trifolium incarnatum (Fabaceae) was widespread and found at various locations including Jeongsil and Woo-do in Jeju-si, Jeju-do and Gasioreum, Daejeong-eup, Seoguipo-si, Jeju-do and Daehandawon Plantation in Hoecheon-myon, Boseong-gun, Jeonranam-do in 2008. Hieracium caespitosum was found to be distinguished from the allied species, H. umbellatum in the same genus, by a lot of capitula and a well developed cluster of basal leaves during the flowering time. Trifolium incarnatum can be distinguished from other species in the same genus by an erect form, long inflorescence and deep-red flowers.

  • In Pohang area, basaluminite accompanying a little amounts of hydrobasalumnite, super-genetically occurs as whitish cryptocrystalline (2-4 $\mu\textrm{m}$) clay-like aggregates in the vicinity of altered carbonate concretions embedded within mudstones of the Tertiary Yeonil Group. A hydrobasaluminite changed readily into a basaluminite at room temperature in air, and, in turn, into a metabasaluminite when heating to 150$^{\circ}$~30$0^{\circ}C$. For the basaluminite, a monoclinic unit-cellparameters (a=14.845$\AA$, b=10.006$\AA$, c=11.082$\AA$, $\beta$=122.15$^{\circ}$) were calculated by X-ray powder diffraction data. Its basal reflections (001 and 002) are XRD analyses strongly indicate that the aluminum sulphate mineral has a layer structure and, at least, three types of water, i.e., (1) interlayer water (9.0 wt %), (2) crystal water (8.0 wt %), and (3) structural water (19.0 wt %). may present in its lattice. Based on TG-DTG data combined with EDS and IR analyses, a new chemical formula of Al5SO4(OH)134H2O was given to the basaluminite. Field occurrence and stable isotope data ($\delta$18O, $\delta$D, $\delta$34S) for the basaluminite seem to reflect that it was formed by the leached meteoric solution from surrounding mudstones during or after uplifting. An interaction of the acid solution with carbonate concretion and the resultant local neutralization of the fluid rich in Al3+ and SO42- are major controls on the basaluminite formation.
