The self-efficacy as the mediating variable to connect knowledge to behavior was Identified as the most powerful predictor that determines behavior. The purpose of this study was, first, to develop the slides /tape program based on the self-efficacy theory of Bandura(1977) second, to investigate that the Slides /Tape program would increase self-efficacy and self-care in patients with hypertension. The subjects for this study were 54 hypertensive outpatients and data collection was carried out from January 9, 1995 until March 18, 1995. The design of this study was one-group pretest and posttest design and the results are as follows 1) The slides /tape program was developed to based on performance accomplishment and vicarious experience which are induction modes of efficacy expectation. It composed of 80 slides and 20 minutes long tape. 2) The effectiveness of the slides /tape program “The self-efficacy score after giving the slides /tape program will be higher than one before giving the slides /tape program.” was supported (t=3.67, p=0.001). “The self-care score after giving the slides /tape program will be higher than one before giving the slides /tape program.” was supported(t=5.23. 000), 3) A significant difference was found between the self-care and sex. Also, the significant difference was found between the self-care and job. From these results, the slides /tape program is effective to increase the hypertensive patients' self-care.

In order to discern and classify high-quality slides, our research proposes a classification method that utilizes a knowledge structure containing information on the presentation slides. After analyzing whether our knowledge structure captures the content's quality information, we developed a classification method based on the knowledge structure produced from the analysis results. With the proposed method, we compared results classified by quality of presentation slides. Through this comparison, we verified that the slides in the high quality group could be classified and were able to retrieve high quality slides. The results show that, by utilizing the cognitive model of a knowledge structure, our method can increase the effectiveness of classification when search or recommendation is conducted mainly with high-quality slides.

This study investigated the effect of high-rise buildings on the preference for rural landscapes. The study site was a Seoul suburban, Yong-in, which showed typical scenes of rural development. Slides used in the study were taken in Young-in along the national road 45(north-south) and national road 42(east-west). Forty slides reflecting typical characters of Young-in were selected. Among them, ten slides which were selected through factor analysis based on “ruralits”score were used as original slides. They represent ten landscape types. The simulation of original slides was based on the following aspects: a observation distance. number of buildings and landscape types. The preferences for the landscapes were tested by 200 respondents on 40 slides: Distance(2) ${\times}$ Landscape type(10) = 20 slides, Number of buildings(2) ${\times}$ Landscape type(10) = 20 slides. The following results are found: 1) When high-rise buildings are introduced into rural scenes, there are some vulnerable landscape types: the landscape with high “rurality”, the landscape with background skyline and the focal landscape. 2) The observation distance affects landscape preference. The hypothesis that the nearer the distance the lower the preferences, is accepted. However, there are some exceptions in 3 landscape types. 3) The hypothesis that the more the number of buildings, the lower the preferences, is rejected. The result is quite unexpected one. When a single building is introduced in natural scene, it draws more attention as a focal point than a group of buildings, and subsequently the visual impact is stronger.

The adsorption of proteins on the surface of glass slides is essential for the construction of protein chips. Here, we report that a Histidine (His)-tagged protein protein has been efficiently adsorbed on glass coated with nickel. A variety of nickel chloride-coated plates were prepared by the spin-coating method and adsorbed to the His-tagged protein. When the protein was adsorbed onto the surface of a variety of nickel chloride-coated glass slides, the efficiency of protein adsorption was dependent upon the coating conditions such as nickel chloride concentration, the spin speed and the drying temperature. The slides appropriate for protein adsorption were obtained when the slides were coated with 11%(w/w) of $NiCl_2$ at the spin speed of 4000 rpm for 20 sec and then dried at higher than 40°C. The physical properties of their nickel chloride thin layer were characterized by scanning electron microscopy. x-ray diffraction and atomic force microscopy, finding that the nickel chloride particles were around 10 nm in diameter and uniformly crystallized at 101 faces. These results show that nickel chloride-coated slides prepared by the spin-coating method are utilizable for the construction of Histagged protein chips.

Controversial observations on the effect of pre-attached bacteria on the attachment of diatoms to artificial surfaces immersed in seawater have been made. Furthermore, it is not known whether or not pre-attached bacteria on artificial surfaces influence attachment of diatoms in natural seawater. In this study, we used various surfaces to which marine bacteria were pre-attached for different incubation periods. In the first experiment, glass slides were initially attached by marine natural bacteria with different exposure time (0-133 hr) and then immersed into seawater for a certain time period. The attachment of diatoms was not affected by the abundance of pre-attached bacteria (p > 0.05). The maximum abundance of attached diatoms was found on control surfaces, and the minimum abundance on surfaces where attached bacterial abundance was highest. In the second experiment, glass slides and acryl slides, either attached by marine natural bacteria for 6 days or coated by agar, were immersed in seawater. Untreated slides were also employed. On the surfaces of acryl slides with the most abundant attached bacteria ($5.4{\pm}0.02{\times}10^5\;cells\;cm^{-2}$), abundances of attached diatoms were less than those on untreated slides. On the surfaces of glass slides with bacterial abundance of $2.5{\pm}1.0{\times}10^5\;cells\;cm^{-2}$, however, abundances of attached diatoms were not different from those of untreated slides. On the agar-coated slides, the immigration rate and immigration coefficient were on average > 2 folds compared to other surfaces, indicating high rates of diatom attachment on mucilage simulated surfaces. Therefore, it seems that pre-attachment of bacteria is not prerequisite for the attachment of diatoms on artificial surfaces.

To study the X chromesome mosaicism in the cytogenetically pure 45,X Turner syndrome patients, we applied PCR technique using DNAs extracted from archived cytogenetic slides. We amplified the DNAs using nested primers targeted to a highly polymorphic short tandem repeat(STR) of the human androgen receptor gene(HUMARA) for the detection of X chromosome mosaicism. This assay is a very sensitive and useful method which can be applied to the DNAs extracted from archived cytogenetic slides to detect X mosaicism. We have tested 50 normal Korean females to determine whether the HUMARA locus is highly polymorphic among Koreans. 85% of Korean population showed heterozygosity in the HUMARA locus. We analysed the 24 DNAs extracted from archived slides of patients and abortuses with Turner syndrome in cytogenetic analysis. We observed the heterozygosities of 50% from pure 45,X patients, 83% from the patients with mosaic Turner syndrome and 8.3% from the abortuses of pure 45,X. Using the PCR technique of the HUMARA locus in the archived cytogenetic slides, we detected X chromosome mosaicism which could not be detected in cytogenetic analysis.

To maximize the productivity in machining molds and dies, machine tools should operate at high speeds. However, the productivity of mold manufacturing has not increased significantly because CNC milling machines have massive slides, which do not allow rapid acceleration and deceleration during the frequent starts/stops encountered in machining molds and dies. This paper presents the use of composites for these slides to overcome this limitation. The vertical and horizontal slides of a large CNC machine were constructed by bonding high-modulus carbon-fiber epoxy composite sandwiches to welded steel structures using adhesives. These composite structures reduced the weight of the vertical and horizontal slides by 34% and 26%, respectively, and increased damping by 1.5 to 5.7 times without sacrificing the stiffness. Without much tuning, this machine had a positional accuracy of $\pm5\mu\textrm{m}$ per 300 m of the slide displacement.

Heavy-weight head slides may cause excessive inertia impact ＆ moment on the machine tool structure when they move or stop abruptly during operation. Consequently these inertia impact and unbalanced moment bring transient vibrations and rough sliding motions on the machine structure. Machine tool engineers have tried many kind of feed-slide designs in order to solve this problem; for example, the design optimization of the moving structure for minimum weight and maximum stiffness, box-in-box type slide design, and so on. In this article, force and moment equilibrium equations regarding to the inertia force ＆ moment were derived for each one of a mold M/C's head slides. Furthermore, five different design configurations of head slide assembly were reviewed for its design improvement regarding to force ＆ moment calculations and finite element structural analysis results.

In this paper, we consider the method which a secret information is distributed in hard-copied image using visual cryptography that the secret can be identifying simply by human eyes. If slides constructed by patterning, which is one of dithering method, are considered from the viewpoint of visual cryptography, each slides will maintain the shape of original image because these slides have different Hamming weights. Therefore, this method has the advantage that information distributed into slides by stacking them can decode and the shape about the original image can be keeping as well. In this paper, we propose the method which shares the secret information into multiple original images by extension of ONM (Oka-Nakamura-Matsui) method which is devised to embed a secret information on hard-copied image. As a result, this proposed method is applicable to digital watermark because the copyright of image can be identified by stacking an image of owner for verification and the distributed multiple images.
