Postmodern American science fiction authors often dramatize the human fear and hope for the newly emerging artificial life forms. For example, Helen as an advanced artificial intelligence Richard Power's Galatea 2.2 shows that the student's memorizing efforts for exams can be useless someday. In Neal Stephenson's Snow Crash machines are liable to be infected with viruses like human bodies. In He, She and It, Piercy's parallel of an artificial human (Yod) and a mythic personification (Golem) allegorically reveals the pandora-like unpredictable effect of advanced technology. More than the mechanical entities (the diffusion and linear models for Latour), these biologically artificial entities reveal the limitations of even the fantastically idealized technology simply because the human being as the creators or impersonators of these machines are not perfect. Compared to illustrative mechanism, biologically artificial entities (Latour's transition or whirlwind models) are inherently rebellious because of their closeness to the creators. The Butler's organic environmental interaction of the Earthseed convincingly demonstrates how the wrong use of science ruins the holy earth and also how human beings survive through the right use of effective science with the aid of anthroposophy.

Purpose: The purpose of this study was to examine the effect of an individual education program on breast cancer patients who received chemotherapy. Methods: The quasi-experimental design was employed with a nonequivalent control group pre-post test. The study was performed from January 1 to July 30, 2010 for the patients who were firstly treated by A C (Adriamycin, Cyclophosphamide) chemotherapy in a university hospital. Control group was recruited first to prevent treatment diffusion. The experimental group was recruited and received an individual education during 30 minutes. The collected data were analyzed using SPSS 16.0 version. ${\chi}^2$-test, t-test, and the Pearson correlation were implemented in order to examine the effect of the individual education among the patients who are treated by chemotherapy. Results: The experimental group had a greater improvement in self-care knowledge (t=-5.236, p=.001), and self-care performance (t=-6.543, p=.004) than did control group. Moreover, the experimental group had significantly positive correlation between self-care knowledge and self-care performance (r=.494, p=.006) as compared to the control group. Conclusion: The individual education program on cancer patients who were treated by chemotherapy could be utilized as an effective nursing intervention.

Recently interest in the fabrication of LD operated by low current is gradually increasing as fabrication techniques of MQW-LD are progressed. In this viewpoint, theoretical estimation for decreasing the amount of threshold current will be helpful to design and make LD in case that active layer of conventional bulk type RWG-LD structure is replaced with MQW structure. Therefore, the optimum design condition of RWG MQW-LD was obtained from theoretical analysis in order to operate in the weakly index-guided LD and low threshold current. The lateral effective index step has been obtained in RWG MQW-LD structure. Waveguide mechanism including this index step has been investigated by solving the carrier diffusion equation and lateral wave equation. From these theoretical results, the optimum design condition of RWG MQW-LD have been suggested.

The purpose of this study is to determine the distribution of the suspended matter caused by dredging at the northeastern part of Kwangyang Bay and to determine the effect of the single silt protector for it. According to the direction of the tidal current, six sampling stations were chosen from the dredging site to the southeast. At the high tide, the high concentration of the suspended matter was observed below the mid-depth near the dredging site. As the tidal currents were stronger. its concentrations below the mid-depth at the inner stations of the single silt protector were rapidly increased, but those of the outer stations did not show any significant change. The concentrations at the inner stations of the silt protector at that time were from 20~140mg/l and those of the outer stations, which was only about 30 m apart from the inner station, were from 20~30mg/l. It suggests that the large amount of suspended matter caused by dredging were moved to the inner stations near the silt protector at the ebb tide and that the silt protector is very effective for the suspended matter.

The cost of advanced medical technologies is commonly considered to be a major factor in the overall escalation of expenditures on health. The use of computed tomography (CT) scanning has increased dramatically over the past decade. CT has been rapidly adopted, despite their high cost. The aim of this study is to analysis the increasing factor of the frequency of the CT, using the decision tree model. Finally, we propose the effective policy option of diagnostic imaging technology in Korea.

This study measured the change of media properties using Time domain Reflectometry (TDR) and Tensionmeter (TM) to measure volumetric water content of soil affecting in land subsidence and pollutant diffusion under saturation/unsaturated condition by water-level fluctuations. Also, actual water content compared their changes aspect by dry oven test for quantitative determinations of these measured values. In the case of TM, initial unsaturated condition confirmed that range in dimension of each other different according to their establishment depth, but measured values of TM can know that is shown measured value in almost similar measuring range under drain condition after the first injection. Also, the results of TDR showed that can measure enough change of volumetric water content in saturation/unsaturated condition by water-level fluctuations. Therefore, we are judged that TDR measurement equipment is very effective to measure the variations of volumetric water content and water-level being caused in groundwater level fluctuations.

Porous $Co_3O_4$ spheres with bimodal pore distribution (size: 2-3 nm and ~ 30 nm) were prepared by ultrasonic spray pyrolysis of aqueous droplets containing Co-acetate and polyethylene glycol (PEG), while dense $Co_3O_4$ secondary particles with monomodal pore distribution (size: 2-3 nm) were prepared from the spray solution without PEG. The formation of mesopores (~ 30 nm) was attributed to the decomposition of PEG. The responses of a porous $Co_3O_4$ sensor to various indoor air pollutants such as 5 ppm $C_2H_5OH$, xylene, toluene, benzene, and HCHO at $200^{\circ}C$ were found to be significantly higher than those of a commercial sensor using $Co_3O_4$ and dense $Co_3O_4$ secondary particles. Enhanced gas response of porous $Co_3O_4$ sensor was attributed to high surface area and the effective diffusion of analyte gas through mesopores (~ 30 nm). Highly sensitive porous $Co_3O_4$ sensor can be used to monitor various indoor air pollutants.

Software export is very important for developing the domain software industry. Up to now, the study related in this issue is not enough even if exports are not activated. In our study, we treated and analyzed the three SME cases that have each successful record in recent years focusing to sales channels establishment and product localization. This study was done by interviewing the marketing directors mainly, and applied email exchanges, phones, and document analyses. Some implications can be addressed for the potential SME software exports. In the perspectives of sales channels building, the trust for product and firm itself is needed to have a good offshore partners. These are required to make the good relationship with partners, brand value's diffusion, and technical competency. As for product localization, the customization is important to meet the needs for local users effectively. So it is desirable to accept the advisory suggestions from the local consulting experts or representative customers. And the joint export strategy using the platform by linking some related products is effective for SME's software product's export.

According to the requirement of Res.MSC.285(86) for natural gas-fueled engine installations in ships, pump and compressor rooms should be fitted with effective mechanical ventilation system of the under pressure type, providing a ventilation capacity of at least 30 air changes per hour. It generally considered that gas leakage is more likely from a Fueled Gas Supply System(FGS) room as compared to other places, where installed in many kind of machinery or equipments like gas supply high-pressure pipes, valves, flanges and etc. Furthermore, leaked gas may be dispersed in a short time in an enclosed space, especially a FGS room, due to high pressure. However, the present requirement in Res.MSC.285(86) just considers the ventilating capacity of air changes per hour but the capacity of leaked gas. Hence, the current requirements may not meet effectively when enforcing the new propulsion systems as marine fuel. This study is conducted for the purpose of safety evaluation about the dispersion and ventilation efficiency with estimated leakage scenario. Numerical analysis predictions as the result of this paper are explained to know the features of flow pattern and the diffusion of natural gas concentration.
