In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

[1.1.1]Paddlane has an inverted structure at two bridge-head carbon atoms. We will describe the reaction of [1.1.1]Paddlane and [1.1.1.1]Paddlane. The reaction of [1.1.1]propellane with singlet methylene affored 1,3-Dimethylene as the major product and [1.1.1.1]paddlane as the minor products were obtained. The reaction of [1.1.1]propellane with triplet methylene was carried out in the similar conditions. The result afforded 1,3-Dimethylenecylopropane as the major product and various side products were also obtained. But no trace of [1.1.1.1]paddlane was detected. After the synthesis of [1.1.1.1]paddlane, continuously [1.1.1.1]paddlane reacts with iodide. The product that I expected for 1,3-diiodo-tricyclo[1.1.1.1]hexane is different. and has unsymmetrical structure.

Effect of in-situ annealing after the Ge buffer layer growth on the behavior of defects at the interfaces of GaAs/Ge/Si structure grown by molecular beam epitaxy(MBE) were investigated using transmission electron microscopy (TEM) technique. Results show that the threading dislocations toward the GaAs layers were blocked more efficiently at the Ge/GaAs interface, when an in situ thermal annealing at 750℃ for 10 minutes was performed after the Ge buffer layers Growth. It was also observed that dislocation density was independent on the thickness of Ge buffer layer. Neither stacking faults nor microtwins were observed in the samples studied. probably because surface morphology of the Ge buffer layer improved due to the in situ annealing and nucleation of the defects was suppressed a result.

In this paper, we propose a minutiae extraction algorithm using the block 2D FFT from the binarization fingerprint images. At first, binary fingerprint images carry out the histogram equalization and block binarization processing. For extract fingerprint minutiae, we executed the 2D FFT to block that divided into the 32×32 blocks from binarization image. Next step is removing the pseudo minutiae from the block for the minutiae extraction. Removing Pseudo minutiae processes executed the removing horizontal, vertical direction elements and diagonal lines. So that it extracts the core and delta points remained which include the blocks. In the end, we extract the minutiae by removing the block part of the delta point. Also, we gained efficient throughput 88% extraction rate of minutiae to the number of 50 fingerprint image.

The purpose of this study is : (1) to identify the overal level of communication between husband and wife, home management ability (2) to investigate the relations between communication and home management ability (3) to examine the factors affecting the home management ability. For the purpose of this study, I selected the samples from the wives living in seoul, who have husband and children. Among a total of 600 respondents, 418 wives were finally selected as a data sources, and the other were discarded. The data were analyzed by the statistical methods such as the frequency, percentile, t-test, F-test, person's correlation, adn stepwise multiple regression analysis. The significant results are as follows: (1) The communication between husband and wife score was 3.22. To refer to subclassfication, the communication time between husband and wife was two hours for a day. The level of communication style was above average and this imply opened style. The communication frequency was under average, communication agreement was above average. And, this communication between husband and wife differs significantly according to the level of education (husband, wife), income. (2) The management ability score was 2.40. In behavior specific, the home management ability score of control coordination and guidence were relatively high, and that of evaluation and planning were relatively low. In object specific, the home management ability score of money was the highest, and that of knowlege and skill were the lowest. This home management ability differes significantly, according to the level of wife's education, number of children, income, husband's occupation. (3) There were positive correlation between the communication and home management ability. (4) The home management ability was independently affected by the following variables in order : communication agreement, the level of wife's education. Based on the above results, I think that the extension of the communication between husband and wife need, and this will promote wife's home management ability. In addition to that, it is nessary to develop a standard instrument to measure the home management ability effectively.

This study was attempted to investigate the action of acetazolamide on the Na-K- ATPase activity in the rabbit RBC membrane. The red cell ghost was obtained by means of Rossenberg and Guidotti and the amounts of isolated inorganic phosphorus as an index of Na-K-ATPase activity was determined by the method of Fiske and SubbaRow. The Na-K-ATPase activity was expressed as the unit of μM Pi/10min/g-protein. The results obtained are summarized as follows. 1. The Na-K-ATPase activity of the RBC membrane was related to incubation time. but the activity per g-protein was large at the 10 min incubation. 2. The Na-K-ATPase activity was related with protein concentration of incubation medium, while there were no difference the activity per g-protein relatively greater in 90 mg/ml protein. 3. 0.5 and 10.0 mg/ml of acetazolamide was inhibit the Na-K-ATPase activity while 5.0 mg/ml of it enhanced the activity. From the above results, it was suggested that the acetazolamide affect Na^+ transport across the cell membrane by alter the Na-K-ATPase activity.
