Purpose: The purpose of the study was to compare symptoms, medical therapies, and nursing interventions with terminal cancer patients during the last four weeks of their lives in a hospice unit and general units. Method: For the descriptive survey study, data were collected by reviewing the medical records of 243 patients who died of terminal cancer at K hospital in Seoul. The data was analyzed by using Chi-square test and t-test. Result: The study findings are summarized as follows. There were higher frequencies in physical symptoms of constipation, itching sensation, pain, sleeping disturbance, soreness and dysuria for those patients in the hospice unit than those patient in general units. All emotional symptoms were recorded significantly higher for those patients in the hospice unit than those in general units. Regarding the major medical interventions, pain management was used more significantly for those patients in the hospice unit, but antibiotic therapy and resuscitation were used more significantly for those patients in general units. Conclusion: The hospice unit provided more comprehensive nursing interventions including psychological, spiritual, and family cares as well as physiological care for terminal cancer patients. The facts showed that those patients who would need hospice care in general units should be referred to the hospice unit at an appropriate time.

The purpose of the study was to compare symptoms, medical therapies, and nursing interventions with terminal cancer patients during the last four weeks of their lives in a hospice unit and general units. For the descriptive survey study, data were collected by reviewing the charts of 243 patients who died of terminal cancer at K hospital in Seoul. The data was analyzed using Chi-square test and t-test. The study findings are summarized as follows: There were higher frequencies in physical symptoms of constipation, itching sensation, pain, sleeping disturbance, sore, and urinary difficulty for those patients in the hospice unit than those patient in general units. All emotional symptoms were recorded significantly higher for those patients in the hospice unit than those in general units. Regarding the major medical treatments, pain control was used significantly more for those patients in the hospice unit but antibiotic therapy and resuscitation were used significantly more for those patients in general units. The hospice unit provided more comprehensive nursing interventions including psychological, spiritual, and family cares as well as physiological care for terminal cancer patients. The facts showed that those patients who need hospice care in general units should be referred to the hospice unite at an appropriate time.

The defects evaluation of the interior and the surface would be considered as vital characteristics in predicting the total life span of the steel structure. More importantly, the understandings in the interior composite of welding zone and the notifications in the presence, the formation, and the positioning of the non-metallic inclusion are necessary as well, since there were signs of relatively high defect frequency presented in the welding zone. The ultrasonic testing is a highly recommended technique chosen from among other techniques because of variety of advantages in conducting the non-destructive testing for the welding zone. However, the ultrasonic testing had technical disadvantages referred as followings; the problems due to the couplant between the PZT and the specimen, the formations that were miniature and complex, the moving subject, and the high temperature surrounding the specimen. This research was conducted to resolve the technical disadvantages of the contact ultrasonic testing by studying the non-contact ultrasonic testing where the ultrasonic waves were transferred by the laser, and revealing the specimen defects at its interior part and its surface part. The ultimate goal of this research was to develop a non-destructive evaluation applying the laser manipulated ultrasonic method for the steel structure

In this study, we made a comparative study of backpropagation neural network and probabilistic neural network and bayesian classifier and perceptron as shape recognition algorithm of welding flaws. For this purpose, variables are applied the same to four algorithms. Here, feature variable is composed of time domain signal itself and frequency domain signal itself. Through this process, we comfirmed advantages/disadvantages of four algorithms and identified application methods of four algorithms.

Incorporation of the prognostic microphysics scheme to model the grid-resolvable precipitation physics in general circulation models (GCMs) influences the simulated climatology in various ways: 1) the microphysics effect that represents clouds and precipitation processes with ice phases in the bulk microphysics scheme, 2) the cloudiness effect that considers the ice-phase properties in computing fractional cloudiness, 3) the radiation property effect that considers the ice-cloud properties in the radiation algorithm, and 4) the detrainment effect that considers the detrained liquid species from the convective clouds into the stratiform clouds. The individual role of these processes is investigated on a single column model (SCM) and seasonal simulation framework to improve our understanding of the ice-cloud radiation interaction in GCMs. In both the SCM and GCM simulations, the microphysics effect reduces large-scale precipitation, whereas the corresponding temperature changes are not distinct in the GCM simulations. The cloudiness effect is relatively insignificant in both testbeds. The radiation property effect plays an important role in modulating the temperature and moisture in both testbeds by directly influencing the radiative fluxes. The convective cloud detrainment effect reduces the global-mean precipitation significantly in the GCM simulation, whereas its effect is negligible in the SCM testbed. Our study demonstrates that an understanding of the fundamental characteristics of microphysics and associated cloudiness, radiation properties, and their interaction in modulating large-scale features is pre-requisite to the successful implementation of a specific prognostic cloud scheme in GCMs.
