To acquire an industrially useful biocatalyst for the enzymatic synthesis and production of various D-amino acids, 1,300 thermophiles isolated from the soil of Korea were analyzed for D-amino acid aminotransferase (D-AAT) activity. The enzyme activity was found from 110 strains of isolated thermophiles revealing its wide occurrence in thermophiles. Enzyme activity and thermal stability of the D-AAT producers were compared. Finally we have selected four thermophiles as producers of potent biocatalysts for the D-amino acid production; two therrnophiles, Bacillus sp. LK-I and LK-2, having higher specific activity and two thermophiles, B. stearothermophilus KL-01 and Bacillus sp. KLS-0l, having higher thermal stability than the D-AAT producers. Taxonomic and physiological characteristics of the four isolated thermophiles were described herein.

In this study the authors observed changes in response to the dexamethasone suppression test (DST) in depressed patients receiving antidepressants. Among 20 subjects.15 were major depression and 5 were bipolar depression. The 8 of 20 subjects showed psychotic features, and 12 of them did not show any psychotic features at all. All subjects underwent weekly DSTs with simultaneous clinical ratings (Hamilton Rating Scale for Depression-HRSD), both at the day of admission and during treatment. Dexamethasone (Decadron. 1㎎)was administered orally at 11 PM on the day of admission and every Wednesday during subsequent weeks. The results of this study were as follows: 1) The 7 of 20 subjects (35%) were categorized as nonsuppressors and 13 (65%) were as suppressors. 2) There were no significant differences in age, sex, body weight, depressive subtype (unipolar vbipolar), length of admission, HRSD scores at admission and discharge, and clinical outcome between nonsuppressors and suppressors. 3) The results of DST were higher predictably among nonsuppressors than suppressors at the time of admission, but not significant difference at the time of discharge between these subgroups 4) The result of DST were higher among subjects with psychotic features at the time of admission. However, there were no significant differences in DST results at the time of discharge and frequency of nonsuppressive response for DST between these subgroups. 5) There was significant correlation statistically between weekly post-DST cortisol levels in plasma and simultaneous HRSD scores among nonsuppressors, but no significant correlation among suppressors.

A study on the fatigue divides the whole fatigue domain into six zones and therefore can guide the designer as to which prediction tool to use. being a function of crack length and stress amplitude. The fatigue domain has been divided into six different zones, each governed by a separate fatigue regime. The proposed predictions are to be considered as practical curve fitting relations for special case. but these cases can also be fairly general and useful for design purposes. The fatigue diagram can be used to show that experimental results should only be compared when they were measured in the same fatigue zone. and there by avoiding the possibility of confusion

Problems of wastes that pigs produce are increasing rapidly in the hog raising industry nowadays. consequently, the generation volume of excreta also is increasing but most of that is not disposed appropriately and exposed in eco-system therefore the disposal of stock excreta is becoming more and more serious. considering the physical and chemical characteristics of livestock excreta, the pollution loading rate - BOD, COD etc. - is very high. as alternative plan, that is, as one method kind of composisting, the utilization of the soil reformation agent will become one solution in managing the upper problems. also, the flyash of 3.7 million tons are producing every year and about 32.2% of that, 1.18 million ton is recycled as concrete, cement, cementassistance, road etc. consequently, the discharged flyash is not abandoned and a plan of recycling is needed acutely. gypsum of 4.16 million tons in 1998 presently was produced and about 57.2% of that, 2.38 million tons was recycled as cement, construction materials. the present stock is 25 million tons. therefore, in this study, because organic materials can be obtained in pig excreta and calciums can be obtained in gypsum, the small amount of elements can be acquired in flyash for the soil reformation agents, mixing the three materials - pig excreta, gypsum, flyash - adequately, investigated technique of making the soil reformation agents and described below in comparrision with the changes of temperature, PH TOC, T-N, TOC/T-N ratio etc.

In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance vector routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end points is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average data reception rate. At that time, we used evaluation parameters such as node's mobility-stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.293%, 15.914%, 17.238% for 300 mobility-stop second case and 4.809%, 4.264%, 2.956% for 300 mobility-stop second case.

Gastric carcinoma is the most common malignant tumor in korea and many oncogenes have found in gastric carcinoma. The relation between the expression of p53 and c-erbB-2 and the prognosis of patient in gastric adenocarcinoma have studied recently, but it is controversy. To evaluate correlation between the pathologic findings including prognostic factors and the expression of p53 and c-erbB-2, and DNA ploidy, we have performed immunohistochemical staining using 83 cases adenocarcinoma and flow cytometry with 56 cases. The results were as follows; 1) The expression rate of p53 was 45.8% in gastric adenocarcinoma. Differentiated, intestinal, advanced, and lymph node metastatic cases showed higher expression rates than poorly differentiated, diffuse, and non-metastatic cases, without statistically significance. 2) The expression rate of c-erbB-2 was 62.6% in gastric adenocainoma. c-erbB-2 was related to differentiated and intestinal types. Advanced and metastatic cases showed higher expression rates of c-erbB-2 than early and non-metastatic cases, but there was not statistic significance 3) Gastric adenocarcinoma showed correlation of DNA diploidy with poorly differentiated type and aneuploidy with differentiated. 4) DNA diploidy and aneuploidy showed correlation with c-erbB-2 negative and postive cases respectively, but correlation between DNA ploidy with p53 expression was not proved. Above results showed that p53 and c-erbB-2 may be related poor prognosis but there was no statistic significance. DNA aneuploidy and diploidy showed correlation with c-erbB-2 expressed and non-expressed cases, respectively, but not with p53 expression.
