  • This study examined the effect of adhesive tape supplemented with sodium fluoride on the prevention of dental erosion in vitro. Sound bovine tooth samples were selected and divided randomly into the following 4 groups according to the material treatments: group 1, APF gel; group 2, fluoride varnish; and groups 3 and 4, fluoride tape supplemented with 5% NaF in either a methyl cellulose or poly vinyl acetate carrier, respectively. All specimens were submitted to alternate cycles of acid exposure in a cola beverage (pH 4.3) and artificial saliva for $6\;{\times}\;5\;min/day$ over a 5 day period. The micro-hardness was recorded each day and the lesion depth was measured after 5 days. The micro-hardness of the experimental sides of groups 2, 3 and 4 were significantly higher than that of their control sides and the experimental side of group 1 during the experimental period (p<0.05) except on the 5th day. The enamel surfaces of treatment groups 2, 3 and 4 showed significantly higher resistance to mineral loss in terms of the erosion depth (p<0.05) than group 1 and their control sides. There was no statistically significant difference among group 2, 3 and 4, indicating that the fluoride varnish and tapes produce similar results. Fluoride adhesive tapes are effective in reducing the progression of erosion and can be recommended for young patients who are more susceptible to dental erosion.

  • Five types of kiwi jelly were prepared with different rates of pressed kiwi juice and carrageenan, and their quality characteristics such as chemical composition, saccharinity, color, texture, and sensory attributes were measured. There were no significant changes in moisture, crude lipid, carbohydrate, but significant differences were shown in crude ash, crude protein, pH, and acidity. The pH decreased and acidity increased as the amount of added kiwi juice increased. The saccharinity of kiwi jelly increased with increased amount of added kiwi juice. Additionally, the total phenolic content, DPPH radical scavenging activity and content increased with increased amount of added kiwi juice. The hardness, gumminess, and chewiness increased with increased levels of carrageenan. As the amount of added carrageenan increased, the L values of kiwi jelly decreased. Based on the sensory evaluation test, kiwi jelly, JKJ(Jeju Kiwi Jelly)-3 was the best in the flavor, sweetness, texture, and overall acceptability. The chemical composition of JKJ-3 was as follows : moisture $75.1{\pm}0.5%$, carbohydrate $24.2{\pm}0.5%$, crude protein $0.29{\pm}0.05%$, and crude ash $0.44{\pm}0.02%$. The kiwi jelly, JKJ-3 of overall acceptability values in the sensory test for flavor, sweetness, hardness, texture and overall favorite were 3.65, 3.35, 3.35, 3.50 and 3.60, respectively, with the addition of 20% pressed kiwi juice and 2.3% carrageenan.

  • The performances of speech compression schemes appeared to be dependent on the response profiles to compressed stimuli and the features of individual languages to some extent. Although these response profiles were critical in comparing various compression outcomes, the related data were limited in number for Korean monosyllabic words. From the previous study, data from PNT (Preserving No Trait) compression was selected as a base set for comparison. In this study, the outcomes from PPT (Preserving Pitch Trait) and PTT (Preserving Time Trait) were analyzed under the same condition. Then, the properties of these three widely used representative compression schemes were quantitatively compared in normal hearing adults (N=20) for controlled Korean quintet digit sets (0 through 9). Results showed that PPT compression scheme exhibited the best perceptual performances for the Korean quintet digit sets in the final outcomes (PPT>PTT>PNT). The compression ratios of 50% performances were estimated as about 20%, 42%, and 44% for PPT, PTT, and PNT, respectively. The data indicated the influences of the salient psychoacoustic features of the three representative compressions on perceiving Korean monosyllabic digit words. This controlled procedure with monosyllabic quintet sets can evaluate efficiency and effectiveness of other compression schemes and may also contribute to diagnosing auditory processing disorders and fitting special hearing aids with compression issues.

  • As a study on the physico-chemical stability of irradiated food and cosmetics, the effect of gamma irradiation on the color values of some food colorants was evaluated. Amaranth, Fast Green FCF, and Indigo Carmine solutions were prepared with different concentration (0.01 and $0.10\%$), gamma irradiated (0.25, 0.5, 1 and 3 kGy), and then Hunters color (L, a, b, ${\Delta}E$) values were determined. The. gamma irradiation process induced decoloration of the coloring agents. In particular, $0.01\%$ solution showed significant differences in the overall color difference$({\Delta}E)$. The lightness (L value) of Amaranth and Indigo Carmine was increased in proportion to irradiation dose, and their redness (a value) and yellowness (b value) also were increased. The redness (a value) and yellowness (b value) of Fast Green FCF $(0.01\%)$ were increased by gamma irradiation. However, there were no significant spectroscopic differences in $0.10\%$ concentrations of the samples.

  • This experiment investigated the characteristics of salted and fresh Chinese cabbages of different cultivars and using various cultivation methods. We measured the numbers of leaves, sizes, thicknesses, moisture contents, and firmness qualities of fresh Chinese cabbage grown in a plastic house, and outdoors. 'The bulb sizes, leaf thicknesses, and moisture contents of leaves were higher after plastic house cultivation than after growth in the field. Plastic house culture increased the growth rate of Chinese cabbage. Firmness and osmolarity showed better values after outdoor cultivation, however. The growth rates and the levels of chemical components were affected by interactions between cultivation methods and cultivars of Chinese cabbage. The salt levels of salted Chinese cabbage were 1.21.7% (w/w) after cabbages cultivated outdoors were preserved, and 0.91.2 % (w/w) after vegetables grown in a plastic house were treated. The quality properties of postharvest Chinese cabbages after salting varied with cultivation method even when the same cultivars of Chinese cabbage were used. The salt contents of salted Chinese cabbage thus varied with different cultivation methods. The results indicate that the properties of Chinese cabbage vary with the culture systems adapted.

  • The purpose of this study is modeling nursing competencies and reasoning out the core competencies, the ability for 20% of important actions for nursing jobs which can manage the rest 80% so that the competency-based nursing curriculum can be developed. A literature review of the vast studies regarding competencies was done to understand the concepts of competency-based curriculum, competency, and nursing competencies, identifying the relationships among each nursing competency categorized in accordance with those concepts. An exemplified concept map of core competencies for the competency-based nursing curriculum is suggested based on a thorough review of various competency modeling methodologies. The core competencies consist of base competency (theoretical/practical nursing knowledge and skills), practical competency (clinical judgment, patient education, communication, etc.), and personality competency (leadership, sense of responsibility, cooperation, etc.). The circular relationship among them can remain consistent through self-directed learning and critical thinking. Therefore, a nurse who have those core competencies is a knowledge worker, a self-directed learner, and also an effective, professional communicator. Further studies which solidify the concept of nursing competencies should be done, as well as the feedback procedures which evaluate the program outcomes and then reflect the evaluation results in the curriculum should be followed continuously.

  • Purpose: This study is to analyze the prevalence of various intra-articular lesions in patients with traumatic recurrent anterior dislocation of shoulder over 40 years and suggest clinical implications for treatment. Materials and Methods: We retrospectively studied 16 cases that underwent surgical treatment for recurrent anterior dislocation of shoulder from January 2001 to May 2009. There were 9 males and 7 females, and the mean age was 52.7years. We carried out arthroscopic exam for all patients based on standard protocol, which included labrum, capular lesion, cuff, bony lesions. Results: All 16 cases showed Hill-Sachs lesion, 3 patients (19%) had bony Bankart lesion, 6 patients (38%) had labral tear. Capsular tear were found 15 patients (94%). Twelve (75%) had ruptured supraspinatus and 5 (31%) had subscapularis tear. Only one (6%) had SLAP lesion. Conclusion: There was relatively higher incidence of capsular and rotator cuff tears in patients over age 40 years. Preoperative planning to address these lesions is highly recommended.

  • Quorum sensing (QS) is involved in the process of cell-to-cell communication and as a gene regulatory mechanism, which has been implicated in bacterial pathogenicity. Bacteria use this QS system to control a variety of physiological processes. In this study, pomegranate (Punica granatum L.) peel extract (PPE) was first screened for its ability to inhibit QS in bio-reporter strains (Chromobacterium violaceum and C. violaceum CV026). Next, the ability of PPE to inhibit swimming motility and biofilm formation was examined in Y. enterocolitica. Additionally, changes in the expression of specific genes involved in the synthesis of the N-acylhomoserine lactones (AHLs; yenI and yenR) and in the flagellar regulon (fliA, fleB and flhDC) were evaluated by reverse transcription (RT)-PCR. The results show that PPE specifically inhibited and reduced QS-controlled violacein production by 78.5% in C. violaceum CV026, and decreased QS-associated biofilm formation and swimming motility in Y. enterocolitica without significantly affecting bacterial growth. These inhibitory effects were also associated with the down-regulation of gene expression involved in the synthesis of AHLs and in motility. Our results suggest that PPE could be a potential therapeutic agent to prevent enteropathogens in humans, as well as highlight the need to further investigate the in vivo properties of PPE for clinical applications.

  • We studied the effects of vibration stimulation method on upper limbs spasticity in patients with brain lesion. 21 patients with spasticity of the upper limbs selected and divided randomly 3 groups. And then vibratory stimulation was applied to the triceps brachii muscle in group I(n=7), to biceps brachii muscle in group II (n=7), and to both muscles in group III (n=7). Using Neuro-EMG_Micro to investigate the changes in spinal neuronal excitability, F-waves were measured at before and directly after stimulation, and 10 minutes later and 20 minutes later after stimulation especially. MAS(Modified Ashworth Scale) test for muscle tone and MFT(Manual Function Test) for the upper extremity motor function were performed before stimulation and 20 minutes later after stimulation for the purpose of clinical evaluation. In our study, MAS was significant decreased in all groups, F wave and F/M ratio parameters were decreased in all groups and more decreased specially in group III. MFT was increased in group II and III, and more increased specially in group III. Vibration stimulation reduced the neuronal excitability of spinal cord and also muscle tone, and improved the motor function of the upper extremity. These results suggested that vibration stimulation giving to both muscles(triceps and biceps brachii muscle) at the same time was more efficiency in reducing the neuronal excitability of spinal cord and improving the motor function of the upper limbs.
