The seasonal distribution pattern of zooplankton were studied on the basis of the zooplankton samples collected from 9 stations in Jinhae Bay in May, August, November and February, 2001 to 2002. A total of 31 species in 37 taxa was occurred in Jinhae Bay. Copepods were pyedominant through fall to spring and cladecerans in summer. There aye high spatio-temporal fluctuations in the zooplankton abundance in a range of 27 to 28,221 indiv. $m^{-3}$. Of these, an neritic species, Acartia omorri and Oentropages abdominals were predominent in february; Palaealanus parvus s. 1 in November; Penilia avirostris in August. Species diversity was low in the northwestern regims where anoxia layer is occurred in summer, while in the other seasons there was no a great difference between stations. It indicates that the distribution pattern of zooplankton may be seasonally strongly affected by a mechanism of hypoxia formation in Jinhae Bay.

North ore deposits of the Dunjeon gold mine is disseminated-stockworks deposits emplaced in Ordovician Dongjeom quartzite. Six types of fluid inclusions are recongnized in the stage I quartz. Among them polyphase inclusions(type-IV-A, B) are predominent in the lower part of stage I quartz crystals whereas liquid and gas inclusions(type I, II) are abundant in the upper part of the same quartz crystals. Liquid $CO_2$-bearing inclusions(type III-A, B)occur as pseudosecondary inclusions. Solid phases in polyphase inclusions are identified by using scanning electron microscopy combined with energy dispersive x-ray spectroscopy. The solid phases are as follows; halite, sylvite, hydrophyllite, quartz, muscovite, calcite, ankerite, K-Mg-Fe-Al-Si mineral, Ca-Fe-Si mineral, Mg-Al-Si mineral, two kinds of Fe-mineral and Cu-Fe mineral. Results of freezing and heating experiments of fluid inclusions and identification of daughter minerals in polyphase inclusions in the stage I quartz reveal that ore fluids were high saline system NaCl-KCl-$CaCl_2$-$H_2O$ in the earier stage and then evolved to rather simple system NaCl-$H_2O$ in the later stage, and temporally fluid mixing occured with system $CO_2$-$H_2O$. Homogenization temperatures and salinity of fluid inclusions in the stage I range from 290 to $454^{\circ}C$ and from 0.2 to 54.2 wt. % equivalent to NaCl.

It can be assumed that the ocean waves consist of many independent pure sinusoidal components which progress in arbitrary directions. To analyze irregular sea waves, both the spectrum method and the individual wave method have been used. The spectral approach is valid in the region where the water depth is deep and the linear property of velocity distribution is predominent, while the individual wave analysis method in the region where the water depth is shallow and the wave nonlinearity is significant. Therefore, to investigate the irregular wave transformation from the deep water to the shallow water region, it is necessary to relate the frequency spectrum which is estimated by the spectrum analysis method to the i oint probability distribution of wave height, period and direction affected by the boundary condition of the individual wave analysis method. It also becomes important to define the region where both methods can be applied. This study is a part of investigation to establish a systematic approach for analyzing the irregular wave transformation. The region where the spectral approach can be applied is discussed by earring out the experiments on the irregular wave transformation in the two-dimensional wave tank together with the numerical simulation. The applicability of the individual wave analysis method for predicting irregular wave transformation including wave shoaling and breaking and the relation between frequency spectrum and joint probability distribution of wave height and period are also investigated through the laboratory experiment and numerical simualtion.

The grain growth characteristics of dual-phase (${\alpha}+{\gamma}$) containing high Cr-steel have investigate using ${\alpha}$-, ${\gamma}$-single phases and (${\alpha}+{\gamma}$)dual-phase of 12%Cr Steel. The heat treatment has performed at $1000-1200^{\circ}C$ for 1-100hr. The results are as follows : 1) The grain growth rate in (${\alpha}+{\gamma}$) dual phase was substantially slower than that of single grain. 2) The relation between mean grain radius $\bar{{\gamma}}$ and annealing time t is, in general, described as following equation : $$(\bar{{\gamma}})^n-(\bar{{\gamma}_o})^n=K_n{\cdot}t{\cdots}{\cdots}(1)$$ i) In the case of single phase of high Cr steel, Eq.(1) is described as $(\bar{{\gamma}})^2-(\bar{{\gamma}_o})^2=K_2{\cdot}t$ and the grain growth is controlled by boundary migration. ii) In dual phase, the grain growth needs diffusion of alloying elements because the chemical composition of ${\alpha}$- and ${\gamma}$- phases differs from each other. When the volume fraction of ${\alpha}$-, ${\gamma}$-phase was almost equal and ${\gamma}$-phase in the case of 80 and $90%{\gamma}$. Eq.(1) is described as $(\bar{{\gamma}})^3-(\bar{{\gamma}_o})^3=K_3{\cdot}t$ because the grain growth is controlled by volume diffusion iii) In the case of ${\gamma}$-rich phase (80 and $90%{\gamma}$), the grain growth of minor phase (10 and $20%{\alpha}$) is described as $(\bar{{\gamma}})^4-(\bar{{\gamma}_o})^4=K_4{\cdot}t$ because the boundary diffusion is predominent rather than volume diffusion.

To investigate the changes in aerobic and facultative anaerobic oral microflora during remission-induction chemotherapy in patients with acute myeloid leukemia, 10 consecutive patients were studied during a period of 28 days. One day before, during and after the induction therapy, patients were given 10% Betadine solution for mouthrinses after breakfast and kept from eating and drinking. After 3 hours, paraffin-stimulated whole saliva was obtained for 2 minutes and transported to the laboratory. The samples were dispersed and homogenized by use of vortex mixer for 20 seconds. From these samples 10-fold serial dilutions (from 10-1 through 10-3) were prepared. Each dilution of 0.1 ml was plated on duplicate set of one nonselective medium (Blood agar) and four selective media (Sabourauds dextrose agar, Mannitol salt agar, Mac-Conkey agar, SF medium ) using applicator woods. All agar plate were incubated at 37$^{\circ}C$ for 48 hours. The total number of microorganisms was calculated and the percentage distribution of the various microorganisms from each specimen was drawn. 1. The salivary flow rate decreased by 66%, going from 5.38 ml/2min to 1.81 ml/2min over two days during the chemotherapy. 2. The total number of microorganisms in saliva increased by 22%, going from 4.88$\times$105/ml to 6.00$\times$105/ml over two days during the chemotherapy. 3. The salivary flow rate and the total number of microorganisms in saliva were recovered within 28 days after the chemotherapy. 4. The quantitative alteration in oral Enterobacteria, Enterococci, Staphylococci, Cndida during the chemotherapy had no statistical significance. 5. In saliva of the patients with acute myeloid leukemia who ahd intraoral ulcer, Enterobacteria was quantitatively predominent. Our study suggests that chemotherapy-induced transient xerostomia may induce acute oral infection. Consequently, the use of saliva substitute, the removal of intraoral infection source and the consistent oral hygiene care seem to be required to avoid the transmission of potential pathogenes in this group of patients.

Beckwith-Wiedemann syndrome comprises multiple congenital anomalies with a risk of development of childhood tumors. Macroglossia is the predominent finding in Beckwith-Wiedemann syndrome and other findings include postnatal somatic gigantism, abdominal wall defects, nevus flammeus of the face, congenital heart defects, and cleft palate. The aim of this case presentation is to describe the dental treatment of a child with Beckwith-Wiedemann syndrome. A 3-year-old boy with Beckwith-Wiedemann syndrome visited to the Seoul National University Dental Hospital for dental evaluation and treatment. Due to the multiple caries and poor cooperation, we planned to perform the dental procedure under general anesthesia. The dental procedure was successfully performed and there was no airway complications after extubation. This case suggests that general anesthesia may be useful for the patient with uncooperative Beckwith-Wiedemann syndrome, since macroglossia and laryngomalacia may exacerbates airway compromise during dental sedation.

Periapical lesions are developed as a result of inflammatory response to irritants from root canal system. Clinicians remove these irritants from root canal system and seal the root canal space to induce healing of the periapical lesions. Immunopathologic responses may play an important role in development and progression of periapical lesions and periapical lesions contain immunocompetent cells. The purposes of the present study were to analys and to compare the distribution of the immunocompetent cells in the human periapical lesions according to the stage of endodontic treatment using indirect immunoperoxdase technique. Obtained 94 human periapical lesions were devided into four groups: Group 1 : no endodontic treatment(28 samples) Group 2 : root canal enlarged and irrigated(28 samples) Group 3 : root canal filled(29 samples) Group 4: unknown(9 samples) Monoclonal antibodies to examine target cells were UCHL-1 for T lymphocytes(1 : 200, Dakopatt, Denmark), L26 for B lymphocytes(1 : 200, Dakopatt, Denmark), OPD4 for helper T lymphocytes(l : 200, Dakopatt, Denmark) and alpha-1-antichymotrypsin for macrophages(l : 2000, Dakopatt, Denmark). The following results were obtained : 1. All the periapical lesions studied were infiltrated by T lymphocytes, plasma cells, B lymphocytes, and macrophages. T lymphocytes were more infiltrated than B lymphocytes, and B lymphocytes and macrophages were less infiltrated than T lymphocytes and plasma cells(P<0.05 : Oneway ANOVA test). 2. In untreated group and canal irrigated and enlarged group of all the periapical lesions, helper T lymphocytes were predominently infiltrated(P>0.05 : Oneway ANOVA test). 3. In canal filled groups of all lesions except periapical cyst, plasma cells were predominently infiltrated. But, in canal filled group of periapical cyst, helper T lymphocytes were the predominent cells(P>0.05 : Oneway ANOVA test). The above results shows that the immunologic responses play important role in pathogenesis of periapical lesions and the immunologic response involved undergoes certain changes after endodontic therapy.

The studies were conducted to determine the effects of preservatives such as sodium chloride, sodium nitrite, sodium benzoate and sorbic acid on the survival of L. monocytogenes with regard to interaction of temperature, heat and pH of the medium. Inactivation of L. monocytogenes Scott A was more predominent by combination of sodium chloride and the other preservatives than sodium chloride alone, and inactivation was more exhilarated at $4^{\circ}C$ than at $35${\circ}C.$ The organism was not inactivated when sodium chloride, sodium nitrite, sodium benzoate and sorbic acid were added to 3%, 100ppm, 0.1, or lower, respectively, but was inactivated in the concentration increased twice. In TSB(tryptic soy broth) at pH 5.0 or lower, the organism did not grow regadless of the kinds of preservatives, and inactivation effect particularly was prominent in the presence of sodium nitrite and sorbic acid. On the other hand, at pH 6.0 or higher L. monocytogenes gradually increased in numbers and the effects of inhibition was higher in the presence of sorbic acid than in the other preservatives. When the preservatives were added to the concentration commonly used, incubation in TSB at $4^{\circ}C$ gradually resulted in growth of the bacterium and the organism rapidly decreased in numbers at $20^{\circ}C\; or\; 35^{\circ}C$ after incubation for 1 week. When L. monocytogenes was inoculated in TSB containing various preservatives and heated at $55^{\circ}C$ for 30minutes, the organism decreased in numbers at all preservatives. Particularly, viability rate of the organism was the lowest as 0.07% in the presence of sorbic acid.
