  • All steps of the curing process are automatically controlled by preseted program according to stalk positions in flue-cured tobacco. The bulk curing experiment was carried out to evaluate the effect of the basic and modified curing program in curing time schedule of two bulk models in physical properties of cured leaves in a new flue-cured tobacco variety KF 114(Wicotiano tabacum L.). The curing process of KF 114 was prolonged in yellowing and quicker in browning stage than those of NC 82. There was no significant difference in physical properties and chromatic characteristics of the cured leaves between basic and modified program at two bulk models. The ratio of normal leaf color tended to increase and the greenish leaf decreased in the modified curing program of two models, but no difference in the brownish leaf ratio was olserved between two programs.

  • With the era of big data, the big data has been expected to have a large impact in the NPP safety areas. Although high interests of the big data for the NPP safety, only a limited researches concerning this issue are revealed. Especially, researches on the logical/physical structure and systematic design methods for the big data platform for the NPP safety were not dealt with. In this research, we design a new big data pilot platform for the NPP safety especially focusing on health monitoring and early warning services. For this, we propose a tailored design process based on SE approaches to manage inherent high complexities of the platform design. The proposed design process is consist of several steps from elicitate stakeholders to integration test via define operational concept and scenarios, and system requirements, design a conceptual functional architecture, select alternative physical modules for the derived functions and assess the applicability of the alternative modules, design a conceptual physical architecture, implement and integrate the physical modules. From the design process, this paper covers until the conceptual physical architecture design. In the following paper, the rest of the design process and results of the field test will be shown.

  • The purpose of this study was to examine the effects of group task-oriented circuit training (TOCT) based on motor learning applied in conjunction with physical and occupational therapy on functional activity, activities of daily living (ADLs), and quality of life in individuals with chronic stroke. Six chronic stroke patients participated for a duration of 31 weeks. Treatment outcomes were assessed via Chedoke-McMaster Stroke Assessment, the Berg Balance Scale, the Assessment of Motor and Process Skill (AMPS), and the Stroke Impact Scale pre- and post-intervention. The participants exhibited significant improvements in impairment, static and dynamic balance, and mood and emotion after group TOCT. The results of AMPS indicated an improvement in the motor area in 3 of the subjects. In the process area, 4 of the subjects exhibited improvement. The results of this study suggest that TOCT is beneficial to physical functions for chronic hemiparetic stroke patients in community-dwelling.

  • Purpose: This study examined whether there are differences in cognitive styles between orthopedic and neurological physical therapists, and whether these differences change with clinical experience in clinical reasoning. Methods: A survey study was conducted on 88 orthopedic and neurologic physical therapists working in South Korea. The survey items used by May and Dennis (1991) were translated, and only those items related to data-gathering and information-processing were used. Results: The cognitive style was similar in the orthopedic and neurologic physical therapists, but the clinical experience affected the cognitive styles of clinical reasoning. Physical therapists with more than 60 months clinical experience responded most positively to the preceptive and systematic styles in clinical reasoning. Conclusion: These results suggest that physical therapy education should provide physical therapy students with a clinical reasoning process related specifically to a particular clinical field.

  • A study on the semiconductor laser-based atomic absorption spectroscopy was performed for monitoring physical vapor deposition process. Gadolinium metal was vaporized with a high evaporation rate by electron beam heating. Real-time atomic absorption spectra were measured by using tunable semiconductor laser beam at 770-794 nm (center wavelength of 780 nm) and its second harmonic at 388-396 nm. Atomic densities of metal vapor can be calculated from the absorption spectra measured. We plot the atomic densities as a function of the electron beam power and compare with the evaporation rates measured by quartz crystal monitor. We demonstrate that the semiconductor laser-based spectroscopic system developed in this study can be applied to monitor the physical vapor deposition process for other metals such as titanium.

  • A bulk-type Ta material is fabricated using the kinetic spray process and its microstructure and physical properties are investigated. Ta powder with an angular size in the range $9-37{\mu}m$ (purity 99.95%) is sprayed on a Cu plate to form a coating layer. As a result, ~7 mm-sized bulk-type high-density material capable of being used as a sputter material is fabricated. In order to assess the physical properties of the thick coating layer at different locations, the coating material is observed at three different locations (surface, center, and interface). Furthermore, a vacuum heat treatment is applied to the coating material to reduce the variation of physical properties at different locations of the coating material and improve the density. OM, Vickers hardness test, SEM, XRD, and EBSD are implemented for analyzing the microstructure and physical properties. The fabricated Ta coating material produces porosity of 0.11~0.12%, hardness of 311~327 Hv, and minor variations at different locations. In addition, a decrease in the porosity and hardness is observed at different locations upon heat treatment.

  • Purpose: The purposes of this study were to explore and describe the use of restraint on patients and to generate a grounded theory of how the use of restraint affects patients who have been restrained. Methods: Interview data from seven patients with physical restraint was analyzed using the Strauss and Corbin's grounded theory method. Data were collected and analyzed simultaneously. Unstructured and in-depth interviews were conducted retrospectively with patients recalling their memories of ICU following their transfer to general unit. Results: 'Safety belt' was emerged as a core category and it reflected that physical restraint provided a sense of security to patients. On the basis of core category, a model of the experience process of restrained patients in ICU was developed. The experience process were categorized into four stages: resistance, fear, resignation, and agreement. Stages of these proceeds appeared to have been influenced by the nurses' attitude and caring behavior such as the frequency of nurse-patient interaction, repetition of explanation, and empathetic understanding. Conclusion: These findings indicate that patients have mixed feelings towards restraint use, although negative feelings were stronger than positive ones. The result of this study will help nurses make effective nursing intervention.

  • Non-woven fabric is a textile product made by spinning thermoplastic polymers without manufacturing processes such as stretching, doubling, twisting, weaving, and knitting to form a sheet-shaped web in which fibers are tangled with each other, and then combining them by mechanical and physical methods. In addition, the non-woven fabric manufacturing process has various raw material choices, high productivity, so it is a textile manufacturing technology that can have various uses and increase added value. This study was conducted to control the shape and physical properties of products by improving the manufacturing method of melt-blown non-woven fabrics using process technology that easily changes the shape of non-woven fabrics and improves mechanical properties. In particular, it is considered that a non-woven fabric with a thin material shape and improved mechanical properties will be easily applied to a continuous secondary battery manufacturing industry such as roll to roll operation.

  • The fatigue process of the triceps surae was evaluated during a standing heel-rise test, comparising of pre-fatigue and post-fatigue. Sixteen healthy subjects with a mean age of 22.88 years participated. The heel-rise test was performed until exhaustion, and electromyographic activity expressed as mean value and root mean square of the gastrocnemius and soleus muscles were calculated. The average number of heel-rise performed was 63.69$\pm$26.10. The result of this present study indicate that the EMG signal is sensitive to the different muscle fatigue. Mean value and RMS decreased significantly in after fatigue. Significant difference were found between the pre-fatigue and post-fatigue in the total subjects. But there were no significant changes in mean and RMS between the male and female during standing heel-rise test. The present results, showing decreased EMG signal in the triceps surae, could be used as reference when testing the fatigue process in different clinical conditions. Recommendations for standardization of a heel-rise test are given.
