Purpose: This study was to explore the process of belongingness experienced during the apprentice course for advanced practice nurses. Methods: Data were collected through in-depth interviews with 15 people, who attended the apprentice course for advanced practice nurse, from three schools in Seoul from Jan. 19 until Feb. 25, 2010. The constant comparative method was adapted for data analysis. Results: The core category of this study was the 'learning-connected process' and this process was categorized into three stages. These stages were: going along with the atmosphere, exchanging, and integrating. During the course, the 'uncomfortable participation' as the central idea meant a sense of responsibility and a tension about practice learning of the participant and was influenced by the quality of interaction and the distinct instruction of learning contents. Belongingness was characterized by the Joyful and happy participation which linked to the motivation of new learning opportunities. Conclusion: The findings indicate that there is a process to belongingness and a close relationship between belongingness and learning. Further studies would suggest exploring the components of belongingness, a concept analysis and incorporating the belongingness scale with other qualitative research on this topic.

An analysis is performed to investigate the influence of the buoyancy force and the thickness variation of melting layer in the containment that is filled with phase-change Material surrounding a cylindrical heating tube during melting process. The phase-change material is assumed to be initially solid at its phase-change temperature and the remaining solid at any given time is still at the phase-change temperature and neglecting the effect of heat transfer occuring within the solid. At the start of melting process, the thickness of melting layer is assumed to be a stefan-problem and after the starting process, the change of temperature and velocity is calculated using a two dimensional finite difference method. The governing equations for velocity and temperature are solved by a finite difference method which used SIMPLE (Semi Implicit Method Pressure linked Equations) algorithm. Results are presented for a wide range of Granshof number and in accordance with the time increment and it is founded that two dimensional fluid flow occurred by natural convection decreases the velocity of melting process at the bottom of container. The larger the radius of heating tube, the higher heat transfer is occurred in the melting layer.

In this paper, in order to analyze the characteristics of degradation by salt water with insulation cover and OC wire(outdoor cross-linked polyethylene insulated wire) used in power receiving system, an experimental apparatus has been designed and fabricated. An insulation cover and OC wire were installed in an experimental apparatus, and degraded in each case of 2%, 5%, 10% salinity during 12 weeks. An optical microscope was used to observe a changing process of sample surface, and an electrical safety was analyzed by measuring dielectric breakdown voltages of samples. As salinity increased, so ununiformity of sample surface increased. The breakdown wasn't produced to 50kV about samples regardless of salinity, testing period.

Many researchers addressed a strong need for providing diverse senior housing options to accommodate different demands from the growing senior population in Korea. One option can be the university-based retirement community (UBRC) which is linked to the adjacent universities and offers various physical, educational, and recreational programs for residents. The primary purpose of this study was to identify major features of the UBRC in terms of development, management, level of college participation, and types of care services for senior residents and to suggest future implementation directions in Korea. Two cases from the United States were selected and investigated to accomplish this goal. Main features of the UBRC were identified as follows: The university linked to each subject community was strongly involved in the development process. Their original residents were mainly recruited from university retirees. The strong university involvement became diminished as the retirement communities got settled down. This study analyzed these architectural, managerial, and development features and suggested future implication directions of university-based retirement communities in Korea.

The equality relation is very important in mechanical theorem proving procedures. A proposed inference rule called RHU-resolution is intended to extend the hyperparamodulation[23, 9] by introducing a bidirectional proof search that simultaneously employs a forward reasoning and a backward reasoning, and generalize it by incorporating beneflts of extended hyper steps with a preprocessing process, that includes a subsumption check in an equality graph and a high level planning. The forward reasoning in RHU-resolution may replace the role of the function substitution link.[9] That is, RHU-deduction without the function substitution link gets a proof. In order to control explosive generation of positive equalities by the forward reasoning, we haue put some restrictions on input clauses and k-pd links, and also have included a control strategy for a positive-positive linkage, like the set-of-support concept, A linking path between two end terms can be found by simple checking of linked unifiability using the concept of a linked unification. We tried to prevent redundant resolvents from generating by preprocessing using a subsumption check in the subsumption based eauality graph(SPD-Graph)so that the search space for possible RHU-resolution may be reduced.

At what level of orthographic representation is phonology linked in thelexicon? Is it at the whole word level, the syllable level, letter level, etc? This question can be addressed by comparing the two scripts used in Korean, logographic Hanmoon and alphabetic/syllabic Hangul, on a task where judgements must be made about the phonology of a visually presented word. Four experiments are reported using a "homophone decision task" and manipulating the sub-lexical relationship between orthography and phonology in Hanmoon and Hangul, and the lexical status of the stimuli. Hangul words showed a much higher error rate in judging whether there was another word identically pronounced than both Hangul nonwords and Hanmoon words. It is concluded that the relationship between orthography and phonology in the lexicon differs according tn the type of script owing to the availability of sub-lexical information: the process of making a homophone derision is based on a spread of activation exclusively among lexical entries, from orthography to phonology and vice versa (called "Orthography-Phonology-Orthography Rebound" or "OPO Rebound"). The results are explained within the mulitilevel interactive activation model with orthographic units linked to phonological units at each level.

Anodized tubular titania ($TiO_2$) electrodes (ATTEs) are prepared and used as both the photoanode and the cathode substrate in a photoelectrochemical system designed to split water into hydrogen with the assistance of an enzyme and an external bias (solar cell). In particular, the ATTE used as the cathode substrate for the immobilization of the enzyme is prepared by two methods; adsorption and crosslinking. Results show that the optimized amount of enzyme is 10.98 units for the slurried enzyme, 3.66 units for the adsorbed one and 7.32 units for the crosslinked one, and the corresponding hydrogen evolution rates are 33.04, 148.58, and 234.88 umol/hr, respectively. The immobilized enzyme, specifically the chemically crosslinked one, seems to be much superior to the slurried enzyme, due to the enhanced charge-transfer process that is caused by the lower electrical resistance between the enzyme and the ATTE. This results in a greater number of accepted electrons and a larger amount of enzymes able to deal with the electrons.

Purpose: The purpose of this study was to compare the importance and performance of nursing interventions linked to five nursing diagnoses in CVA patients. Methods: First, total 37 nursing diagnoses were identified from the analysis of 78 nursing records of CVA patients, and then top 5 diagnoses were mapped with nursing interventions. Second, each intervention was compared in terms of importance and performance by 80 nurses working at neurosurgical units from 5 general hospitals. Data were analyzed using mean, SD, and t-test using the SPSS program. Results: Selected the top five nursing diagnoses were Acute Pain, Risk for Disuse Syndrome, Decreased Intracranial Adaptive Capacity, Ineffective Cerebral Tissue Perfusion and Acute Confusion. In general, most of the interventions were scored higher in importance than performance and most of independent interventions were not performed as frequently as it perceived in importance. The interventions which scored high in performance were the interventions ordered by physician or interventions related to medication behavior. Conclusion: We identified which nursing interventions should be performed more frequently and more critically important to nursing diagnoses. We recommend further research that enhances the performance of nursing interventions to provide better quality of nursing services to the patients in practice.

The high temperature performance of PEM type electrolyser at $120^{\circ}C$ based on covalently cross-linked sulfonated poly ether ether ketone (SPEEK) composie membrane was investigated. Ion conductivity and other properties of SPEEK membrane were improved by adding heteropoly acid and Ceria. The membrane electrode assemblies were prepared using commercial PtC and nano-sized $IrRuO_2$ catalyst by electro-spraying and decal process. Voltage efficiency of MEA equipped with SPEEK membrane was slightly better than that of $Nafion^{(R)}$ membrane, due to its higher proton conductivity at high temperature. The cell performance of MEA with CL-SPEEK/Cs-TSiA/Ceria is 1.71 V at $1A/cm^2$ and $120^{\circ}C$.
