The Effect of Curriculum with voluntary program on Self-Actualization in Nursing Students. The purpose of this study was to identify the effect of the voluntary program experience with curriculum on self-actualization in nursing college students and to guide the desirable voluntary activity of college students. The research design utilized in this study was one group pretest-posttest design. The data were gathered two times with self-actualization test. First data were gathered before voluntary activity. And second data were gathered after instruction and five times voluntary activity. The data were analized by frequency, t-test, paired t-test and ANOVA using the SAS program. The results were as follows: The scores of self-actualization in nursing students belonged to normal range. Before voluntary activity, the scores were significantly higher than standardized group in Nature of Man, Constructive Scale (P<.001), and the scores were significantly lower than standardized group in Feeling Reactivity Scale(P<.05) and Capacity for Intimate Construct Sscale (P<.001). After the activity the scores were significantly higher than standardized group in Self Actualizing Values Scale(P<.001), Existentiality (P<.01), Spontaneity Scale (P<.001). Self Acceptance Scale(P<.05) and Nature of Man, Constructive Scale (P<.001). After the activity the scores were significantly increased more than before the activity in Inner Directed Scale (P<.001). Self Actualizing Values Scale (P<.001), Feeling Reactivity Scale (P<.001), Capacity for Intimate Construct Sscale (P<.001). Spontaneity Scale (P<.01), Time Competent Scale (P<.05) and Existentiality (P<.05). And the scores were not significantly increased more than before the activity in Self Regard Scale, Self Acceptance Scale and Nature of Man, Constructive Scale. The results of this study showed that voluntary activities were effective self-actualization. So, it is thought that voluntary program is necessary in the curriculum for nursing college students. This study suggests as follows : 1) It is necessary to inspect the self-actualization test after various experience of voluntary activity in college students. 2) It is necessary to grope the plans to activate the social service programs. 3) It is necessary to study continious and voluntary social service of college students.

In current complex nature of management with task-structures, a method to reach the enterprise's informationalization success is not common. To satisfy these various requirement, improving the usability of information technology (IT) is a key factor which defining the level of organizational requirement first. Imposing an IT-solution which has excess service of the organization's previous task-environment, procedure and scope is not effective to SME-level unit, which unit could not have a formal organization structure and task structure. SME level informationalization will be success if each function realizes easier on the task-employee's viewpoint. Achieving this objective, a solution provider or department must reflect their work characteristics of nature which has least level of work performing resistance. It is most useful system for SME level unit, if a provider develops single programs which based on task activities, and each program can configure network-linking.

A bioluminescent assay method for detecting the activity of phospholipase C(PLC; phosphatidyl choline cholinephosphohydrolase, EC 3.1.4.3) was developed using bioluminescent marine bacteria. Phospholipase C from Bacillus cereus and sn-1,2- dimyristoyl glycerol was further hydrolyzed with lipase from Candida ecylidracea. The hydrolyzed myristic acid was quantified using a dark mutant of Vibrio harveyi (designated as M-17). The in vivo light intensity of which was stimulated specifically up to one thousand fold in the presence of myristic acid. The rates of the hdrolysis of the DMPC substrate by the phospholipase measured by the luminescence method were linear with time and the were estalished to detect as little as 0.1 mUnit of phospholipase C and 5 nM of myristic acid production.

In this paper, an air isolate (NITT6L) has been screened based on hemolytic activity, emulsification activity, drop collapsing test, and oil displacement test, as well as lipase activity. It was found that strain NITT6L was able to reduce the surface tension of the medium from 61.5 to 39.83 mN/m and could form stable emulsions with tested vegetable oils. Morphological, biochemical, 16S rRNA sequencing analyses, and fatty acid methyl ester analysis using gas chromatography confirmed that the air isolate under study was Pseudomonas aeruginosa. Characterization of the biosurfactant using agar double diffusion assay revealed that the biosurfactant was anionic in nature, and CTAB-methylene blue assay and Molisch test revealed its glycolipid nature. The FT-IR spectrum confirmed that the crude biosurfactant was a rhamnolipid. Using unoptimized medium containing sucrose as the carbon source, the isolate was found to produce 0.3 mg/ml of rhamnolipid in batch cultivation (shake flask) at $37^{\circ}C$ and pH 7. Optimization of the medium components was carried out using design of experiments and the yield of rhamnolipid has been enhanced to 4.6 mg/ml in 72 h of fermentation.

The smart design of nanocatalysts can improve the catalytic activity of transition metals on reducible oxide supports, such as titania, via strong metal-support interactions. In this work, we investigatedtwo-dimensional Pt nanoparticle/titania catalytic systems under the CO oxidation reaction. Arc plasma deposition (APD) and metal impregnation techniques were employed to achieve Pt nanoparticle deposition on titania supports, which were prepared by multitarget sputtering and sol-gel techniques. APD Pt nanoparticles with an average size of 2.7 nm were deposited on sputtered and sol-gel-prepared titania films to assess the role of the titania support on the catalytic activity of Pt under CO oxidation. In order to study the nature of the dispersed metallic phase and its effect on the activity of the catalytic CO oxidation reaction, Pt nanoparticles were deposited in varying surface coverages on sputtered titania films using arc plasma deposition. Our results show an enhanced activity of Pt nanoparticles when the nanoparticle/titania interfaces are exposed. APD Pt shows superior catalytic activity under CO oxidation, as compared to impregnated Pt nanoparticles, due to the catalytically active nature of the mild surface oxidation and the active Pt metal, suggesting that APD can be used for large-scale synthesis of active metal nanocatalysts.
