This study was conducted to investigate the staging principle, the staging work and the trial performance of Shingeuk troupe Geukyesulyeonguhoe during the period of coterie system, focusing on Gogol work·Ham Daehoon translation·Hong Haeseong directing's (5Act). As a result, the first trial performance was based on a faithful full-scale description rather than an interpretive directing of play. It was a performance that focused on copying and implanting the external form of the performance stage of Shingeki troupe Tsukiji Little Theater. The general review of the time was summarized to the point that it was a relatively successful performance that exceeded expectations as a trial demonstration of amateur actors. However, in terms of the content of play and the form of performance, reservations and lack of contemporary(modern) interpretation caused the problem that the general audience was alienated. Therefore, it was difficult to achieve the effect of reflecting the reality of Chosun through , as Geukyesulyeonguhoe intended.

The goal of medicine is to contribute to promoting national health by preventing diseases and providing treatment. The scope of modern medicine isn't merely confined to disease testing, treatment and prevention in accordance to that, and making experiments by using the human body is widespread. The advance in modern medicine has made a great contribution to valuing human dignity and actualizing a manly life, but there is a problem that has still nagged modern medicine: treatment and healing for terminal patients including cancer patients. In advanced countries, pain care and hospice medicine are already universal. Offering a helping hand for terminal patients to lead a less painful and more manly life from diverse angles instead of merely focusing on treatment is called the very hospice medicine. That is a comprehensive package of medical services to take care of death-facing terminal patients and their families with affection. That is providing physical, mental and social support for the patients to pass away in peace after living a dignified and decent life, and that is comforting their bereaved families. The National Hospice Organization of the United States provides terminal patients and their families with sustained hospital care and home care in a move to lend assistance to them. In our country, however, tertiary medical institutions simply provide medical care for terminal patients to extend their lives, and there are few institutional efforts to help them. Hospice medicine is offered mostly in our country by non- professionals including doctors, nurses, social workers, pastors or physical therapists. Terminal patients' needs cannot be satisfied in the same manner as those of other patients, and it's needed to take a different approach to their treatment as well. Nevertheless, the focus of medical care is still placed on treatment only, which should be taken seriously. Ministry for Health, Welfare & Family Affairs and Health Insurance Review & Assessment Service held a public hearing on May 21, 2008, on the cost of hospice care, quality control and demonstration project to gather extensive opinions from the academic community, experts and consumer groups to draw up plans about manpower supply, facilities and demonstration project, but the institutions are not going to work on hospice education, securement of facilities and relevant legislation. In 2002, Ministry for Health, Welfare & Family Affairs made an official announcement to introduce a hospice nurse system to nurture nurse specialists in this area. That ministry legislated for the qualifications of advanced nurse practitioner and a hospice nurse system(Article 24 and 2 in Enforcement Regulations for the Medical Law), but few specific plans are under way to carry out the regulations. It's well known that the medical law defines a nurse as a professional health care worker, and there is a move to draw a line between the responsibilities of doctors and those of nurses in association with medical errors. Specifically, the roles of professional hospice are increasingly expected to be accentuated in conjunction with treatment for terminal patients, and it seems that delving into possible problems with the job performance of nurses and coming up with workable countermeasures are what scholars of conscience should do in an effort to contribute to the development of medicine and the realization of a dignified and manly life.

The purpose of this study is two things. First, it is to develop and demonstrate a sharong taxi platform. To this end, the implications for platform development were derived by analyzing consumers' perceptions of existing taxi services using IPA. As a result, abnormal business activities and safe services in the maintenance area were found to be safe rides and easy rides in the key improvement area. Safety such as usage fee level and driver information provision were derived in the areas subject to improvement, and friendly response and internal and external cleanliness were derived in the areas of excessive investment. The second purpose of this study is to estimate the value given to users for sharing taxi service platforms using the CVM. As a result of estimating the value of the demonstration service of the shared taxi platform developed through this study, the WTP was 3,621 won/per household/per year when expanding throughout Gimhae-si, and 2,515 won/per household/per year. Compared to the willingness to pay for empirical services, only 69.5% of the willingness to pay for the spread project in Gimhae-si. This is the result of a combination of service spread to an unspecified number of people and concerns about service quality due to spatial expansion. This suggests that it is necessary to build data through continuous demonstration and to carefully build a roadmap for spread by upgrading services based on this.

Purpose: The aim of this project was to develop a patient safety-focused inservice education program for surgical nurse and to test the effects of this program. Methods: Methodological designs for instruments development, a pretest-posttest and a posttest design were employed. After the education, nurses' satisfaction, confidence, usefulness and application of 137 nurses were evaluated at 15 surgical units of a tertiary teaching hospital in Seoul, Korea. The education contents are 6 skill areas (infusion pump use, suction, chest tube drainage, oxygen administration, nebulizer use, insulin administration) and medication knowledge. Teaching methods were lecture, instructor demonstration, and 1:1 skill test. Descriptive statistics, Wilcoxon test, Spearman's correlation and Stepwise regression were used. Results: Satisfaction scores for skills and medication education were 4.00-4.21 (out of 5), The more performance frequency in 6 skills, the higher score in confidence as well as in usefulness and application, and the higher satisfaction with the program, the higher score in usefulness, application, confidence, and medication knowledge. Medication knowledge improved after the education (Z=-7,757, p<.001). Significant predictors of skill confidence were application of skills in job performance, medication confidence, and career in present unit. Conclusion: The results of this study suggest that systematic and continuous inservice education will improve patient safety by promoting nursing quality.

This talk will begin with the demonstration of facile synthesis of silicon nanostructures using the magnesiothermic reduction on silica nanostructures prepared via self-assembly, which will be followed by the characterization results of their performance for energy storage. This talk will also report the fabrication and characterization of highly porous, stretchable, and conductive polymer nanocomposites embedded with carbon nanotubes (CNTs) for application in flexible lithium-ion batteries. It will be presented that the porous CNT-embedded PDMS nanocomposites are capable of good electrochemical performance with mechanical flexibility, suggesting these nanocomposites could be outstanding anode candidates for use in flexible lithium-ion batteries. Directed self-assembly (DSA) of block copolymers (BCPs) can generate uniform and periodic patterns within guiding templates, and has been one of the promising nanofabrication methodologies for resolving the resolution limit of optical lithography. BCP self-assembly processing is scalable and of low cost, and is well-suited for integration with existing semiconductor manufacturing techniques. This talk will introduce recent research results (of my research group) on the self-assembly of Si-containing block copolymers for the achievement of sub-10 nm resolution, fast pattern generation, transfer-printing capability onto nonplanar substrates, and device applications for nonvolatile memories. An extraordinarily facile nanofabrication approach that enables sub-10 nm resolutions through the synergic combination of nanotransfer printing (nTP) and DSA of block copolymers is also introduced. This simple printing method can be applied on oxides, metals, polymers, and non-planar substrates without pretreatments. This talk will also report the direct formation of ordered memristor nanostructures on metal and graphene electrodes by the self-assembly of Si-containing BCPs. This approach offers a practical pathway to fabricate high-density resistive memory devices without using high-cost lithography and pattern-transfer processes. Finally, this talk will present a novel approach that can relieve the power consumption issue of phase-change memories by incorporating a thin $SiO_x$ layer formed by BCP self-assembly, which locally blocks the contact between a heater electrode and a phase-change material and reduces the phase-change volume. The writing current decreases by 5 times (corresponding to a power reduction of 1/20) as the occupying area fraction of $SiO_x$ nanostructures varies.

The goal of this study is to measure and compare the performance of solar heat pump for room and hot water heating. To accomplish the goal, solar heat pump with alumium roll bond type evaporator and indoor heat exchanger(condenser) was built and fully instrumented with thermocouples and pressure transducers etc. The test results showed that the COP(coefficient of performance) of HFC-134a($CF_3CH_2F$) were higher than those of CFC-12($CF_2Cl_2$). One "stratospherically safe" new refrigerant is 1,1,1,2-tetrafluoroethane(HFC-134a), which is thermodynamically similar to CFC-12 and considered to be a potential direct replacement for CFC-12 in air-conditioning and refrigeration applications. The solar heat pump system for room heating was designed to show the best efficiency that the room temperature make $18{\sim}20^{\circ}C$ and $23{\sim}25^{\circ}C$ in the southern part of South Korea during November, December, and January.

These excavators have been widely used due to their flexibility in handing various tasks via simple changes of their attachments. Since the performance of manually-operated excavators heavily depend on the operators' skill level, there is a strong need for developing automatic excavators in the industry. In order to achieve such goals, exiting approaches have studied direct modification of existing hydraulic systems in the excavator for feed back control of each link. This paper presents a miniaturized automatic excavator that can be used for the development and demonstration of advanced control algorithm for excavators under a safer environment with reduced cost. Two PCs were installed and connected to the excavator through wireless communications for its control and monitoring. Tracking control of each link using a time varying sliding mode controller was performed through experiments on the developed system to demonstrate its ability.

This paper presents design and simulation of wide band RF microswitch that uses electrostatic actuation for its operation. RF MEMS devices exhibit superior high frequency performance in comparison to conventional devices. Similar techniques that are used in Very Large Scale Integration (VLSI) can be employed to design and fabricate MEMS devices and traditional batch-processing methods can be used for its manufacturing. The proposed switch presents a novel design approach to handle reliability concerns in MEMS switches like dielectric charging effect, micro welding and stiction. The shape has been optimized at actuation voltage of 14-16 V. The switch has an improved restoring force of 20.8 μN. The design of the proposed switch is very elemental and primarily composed of electrostatic actuator, a bridge membrane and coplanar waveguide which are suspended over the substrate. The simple design of the switch makes it easy for fabrication. Typical insertion and isolation of the switch at 1 GHz is -0.03 dB and -71 dB and at 85 GHz it is -0.24 dB and -29.8 dB respectively. The isolation remains more than - 20 db even after 120 GHz. To our knowledge this is the first demonstration of a metal contact switch that shows such a high and sustained isolation and performance at W-band frequencies with an excellent figure-of merit (fc=1/2.pi.Ron.Cu =1,900 GHz). This figure of merit is significantly greater than electronic switching devices. The switch would find extensive application in wideband operations and areas where reliability is a major concern.
