Background: Epidural steroid injections benefit certain patients with radicular pain, and often have only a limited duration. We compared the efficacy of hyaluronidase and triamcinolone and triamcinolone alone in patients with lumbar herniated disc disease treated with transforaminal epidural block. Methods: Forty patients who had undergone a transforaminal epidural injection were retrospectively reviewed. The T group received triamcinolone and local anesthetics; whereas, the HT group received hyaluronidase, triamcinolone and local anesthetics. We evaluated the improvement as being good, moderate, mild or no improvement, and in those where the improvement was good or moderate, also evaluated the duration of pain relief. Data were collected from the medical records of patients or via phone calls, which were analyzed using Student t- and chi-squared tests. A value of P < 0.05 was considered significant. Results: There were no significant differences in the degree of pain improvement or duration of pain relief between the two groups. Conclusions: A hyaluronidase and triamcinolone injection during transforaminal epidural block has on benefit with respect to the degree of pain improvement or its duration compared to a triamcinolone only injection.

Purpose: This study was to identify the symptom severity, interference and their psychological predictors in thyroid cancer patients hospitalized for radioactive iodine administration. Methods: One hundred seventy-seven thyroid cancer patients admitted to the isolation room for Iodine ($I^{131}$) therapy were recruited. Subjects were asked to complete the questionnaire on core symptoms, thyroid cancer symptoms, interference, depression and state anxiety in the evening after receiving radioactive iodine therapy. Data was analyzed using frequency, percentage, mean, Pearson's correlation, and multiple regression with SPSS vs. 19. Results: Lack of appetite, drowsiness, sleep disturbance, fatigue, and nausea were the 5 most core symptoms. More than 20% of patients experienced moderate to severe thyroid cancer symptoms including feeling cold, hoarseness, swallowing difficulty, and feeling hot. More than 30% of subjects experienced moderate to severe interferences in mood, general activity, and 22% in walking. Depression and state anxiety were identified as predictors of core symptoms, thyroid symptom severity and interference. Conclusion: Nursing interventions to reduce the symptom severity and interference need to be developed by considering thyroid cancer patients' depression and anxiety when hospitalized in the isolation room for radioactive iodine administration.

Purpose - This study examines the relationship between organizational justice and employee job satisfaction and the extent of its moderation by perceived alternative job opportunities. Research design, data, and methodology - This is a cross-sectional study utilizing survey questionnaire data from 220 bank employees, which included scales measuring organizational justice, job satisfaction, and perceived alternative job opportunities. Results - The data is analyzed using correlation and hierarchical regression. Results demonstrated that organizational justice has a direct positive impact on employee job satisfaction further, distributive justice explains more variance in job satisfaction, followed by procedural justice and interactive justice. Perceived alternative job opportunities moderate the relationship between organizational justice and job satisfaction. Conclusions - Generally, organizational justice increases bank employees' job satisfaction; however, when they perceived more job opportunities, their job dissatisfaction increased notwithstanding fairness. Therefore, perceived job opportunities moderate the relationship between organizational justice and job satisfaction. Retaining skilled employees has become difficult, especially when there is market demand for skilled workers. Human resource (HR) managers should consider market situations before formulating policies; otherwise, they may lose the competitive advantage of skilled employees and workers.

The present investigation was carried out to determine the efficacy and safety of Abutilon indicum (A. indicum) (Eng: Country Mallow, Fam: Malvaceae) in patients of bronchial asthma. Dried aerial parts of A. indicum were finely powdered and given in the dose of 1 gm tid to 30 patients of either sex in the range of 15 - 80 years with mild to moderate bronchial asthma with or without any concurrent medication. The respiratory functions (FVC, $FEV_{1}$, $FEF_{25-75%}$and MVV) were assessed using a spirometer prior to and after 4 weeks of treatment. Efficacy of the drug in improving clinical symptoms and severity of asthmatic attacks was evaluated by interviewing the patient and by physical and hematological examination at the end of the treatment. 4 weeks treatment with the drug showed statistically significant improvement in various parameters of pulmonary functions in asthmatic subjects. Also significant improvement was observed in clinical symptoms and severity of asthmatic attacks. None of the patient showed any adverse effect with A. indicum. The results of the present study suggest the usefulness of A. indicum in patients with mild to moderate bronchial asthma.

Recently, Aerosol Deposition method has attracted considerable attention because of its advantages to produce ceramic coatings on various substrates at room temperature. This method is strongly dependent on the raw powder, which should have high mobility with carrier gas and moderate mechanical strength to be crushed onto the substrate. In this report, the effects of the ceramic granules' compressive strength on the ceramic coating formation are discussed. The ceramic granules were prepared by spray-drying method and heat treated at various temperatures. It was found that at the moderate mechanical strength of ceramic granules gave more effective film formation behavior during Aerosol Deposition method.

This paper reports the hot carrier induced RF performance degradation of bulk dynamic threshold voltage MOSFET (B-DTMOS) compared with bulk MOSFET (B-MOS). In the normal and moderate mode operations, the degradations of cut-off frequency $(f_{T})$ and minimum noise figure $(F_{min})$ of B-DTMOS are less significant than those of B-MOS devices. Our experimental results show that the RF performance degradation is more significant than the U performance degradation after hot carrier stressing. Also, the degradation characteristics of RF power Performance of B-DTMOS due to hot carrier effects are measured for the first time.

Medicinal plants are potential sources of anticancer agents screening. A large number of phytochemicals, including triterpenoids, have been reported to have significant cytotoxic effects on cancer cells. From the fruits of Ligustrum japonicum Thunb., thirteen triterpenoids (1 - 13) were isolated and evaluated for their cytotoxic activity against Hela and HL-60 cells. As results, 8 (oleanolic acid) showed significant effects on Hela with $IC_{50}$ values of $5.5{\mu}M$, and moderate effects on HL-60 cells with $IC_{50}$ values of $55.9{\mu}M$. Meanwhile, 10 (oleanderic acid) and 11 ($3{\beta}$-acetoxy-urs-12-en-28-oic acid) exhibited moderate inhibitory effects on Hela with $IC_{50}$ value of 55.0 and $68.8{\mu}M$, respectively. Moreover, 10 showed cytotoxic effect on HL-60 cell line with $IC_{50}$ value of $63.9{\mu}M$. To our knowledge, this is the first report that oleanderic acid was isolated from L. japonicum and investigated in cytotoxic effects on Hela and HL-60 cells.

Aerobic capacity is an important health indicator which is related to the probability of disease, disability, and mortality. Typically, endurance exercise is known as the primary method of improving aerobic capacity. Although most of resistance exercises are not considered for a good method increasing aerobic capacity, low to moderate intensity resistance exercise with short rest periods may improve aerobic capacity, especially old adults and most low to moderate risk patients suffering from CAD. This review is to understand that a number of physiological changes occur during both aerobic and resistance exercise, and to support that resistance exercise has advantages for improving aerobic capacity.

Lap splice in plastic hinge region is inevitable because of due to constructional joint between footing and column. R/C Circular columns with lap-splice in plastic hinge region are widely used in Korean highway bridges. In addition, these columns which constructed before the seismic design code have a number of structural deficiencies. It is, however, believed that there are not many experimental research works for nonlinear behavior of these columns subjected to earthquake motions. The object of this research is to evaluate the seismic performance of existing circular reinforced concrete bridge piers by the Quasi-static test. Existing reinforced concrete bridge piers were moderate seismically designed in accordance with the conventional provisions of Korea Highway Design Specification. This study has been performed to verify the effect of lap spliced longitudinal steel, confinement steel type and confinement steel ratio far the seismic behavior of reinforced concrete bridge piers. Quasi-static test has been done to investigate the physical seismic performance of RC bridge piers, such as displacement ductility, energy absorption, strength degradation etc.

Meats with alginate binders including sodium alginate, glucono-delta-lactone and calcium carbonate were tested in restructured steaks made from M. pectoralis profundus of beef steers in terms of meat quality and binding ability by tumbling time. The treatment with 25 min tumbling time was significantly lower (p<0.05) for crude protein than 5 and 15 min, while higher (p<0.05) for moisture content. This corresponded with sensory panel juiciness ratings, which showed the treatment for longer tumbling times to be significantly juicier (p<0.05) than that for a shorter time. Cooking loss decreased (p<0.05) linearly with an increased tumbling time, and Kramer shear force also significant decreased (p<0.05) with tumbling time. This corresponded with sensory panel tenderness ratings, which showed that the treatment for longer tumbling times was more tender (p<0.05). The texture results indicated that longer tumbling time had lower (p<0.05) hardness and chewiness values. Sensory panels ranked binding ability in the order 5 min, 15 min and 25 min from best to worst, and the overall acceptability for slices from roasts of treatments for 5 and 15 min were rated by the sensory panelists as moderate to very acceptable, but those for 25 min were rated as fair to moderate.
