  • Background: The research examined the effect of a scapular stabilizing exercise on shoulder pain, active range of motion (AROM) and changes in the position of the shoulder blade of patients with frozen shoulder. Methods: General physical therapy and a scapular stabilizing exercise were applied to a 53-year-old female patient with frozen shoulder three times a week for four weeks. Before and after the therapy, measurements were made on the visual analog scale (VAS) and of the AROM, and a lateral scapular slide test was conducted. Results: Following the therapy, VAS fell from 7 to 3. Before therapy, flexion, abduction, internal rotation, and external rotation recorded $133^{\circ}$, $102^{\circ}$, $45^{\circ}$, and $53^{\circ}$ respectively; after the therapy they increased to $150^{\circ}$, $123^{\circ}$, $55^{\circ}$, and $65^{\circ}$ respectively. The lateral scapular slide test showed sliding distances before therapy of 8.5cm at $0^{\circ}$, 9.2cm at $45^{\circ}$, and 11.3cm at $90^{\circ}$; after therapy, the distances decreased to 6.8 cm at $0^{\circ}$, 8.2 cm at $45^{\circ}$, and 9cm at $90^{\circ}$. Conclusion: The scapular stabilizing exercise was effective in alleviating shoulder pain, increasing AROM, and reducing changes in the position of the shoulder blade of frozen shoulder patients.

  • Austenite stainless steel(SA213-TP347H) has widely been used for the superheater & reheater tube in USC(ultra-supercritica) coal boiler because of its high creep rupture strength and anti-oxidation. But recently, the short-term failures have happened frequently in heat affected zone for only 4,000~15,000hours of service. Many investigations have been conducted to understand the failure mechanism. The root cause of failure was comfirmed to "strain induce participation hardening crack" or "reheat cracking". This mechanism often occurred due to weld residual stress and precipitation of the Cr, Nb carbides in the stabilized stainless steel such as TP347H. This paper presents an analysis of failure tube and effect of the sample tubes that conducting stabilizing heat treatment in site after 11,380hours & 16,961hours of service. Visual inspection was performed. In addition, microscopic characteristics was identified by O.M, SEM, and hardness test was carried out to find out the heat treatment effects. Failures seem to happen because of being not conducted stabilizing heat treatment in site. And another cause is inadequate weld parameter such as pass, ampere, voltage, inter-pass temperature. Thus, this paper has the purpose to describe that how to prevent similar failures in those weld-joints.

  • The effect of stabilizing piles on cut slopes is checked and the behavior of slope soil and piles are observed throughout the year by field measurements on the large-scale cut slopes. First of all, the behavior of the slope soil was measured by inclinometers during slope modification. Landslides occurred in this area due to the soil cutting for slope modification. The horizontal deformations of slope soil are gradually increased and rapidly decreased at depth of sliding surface. As the result of measuring deformation, the depth of sliding surface below the ground surface can be known. Based on the measuring the depth of the sliding surface, some earth retention system including stabilizing piles were designed and constructed in this slope. To check the stability of the reinforced slope using stabilizing piles, an instrumentation system was installed. As the result of instrumentation, the maximum deflection of piles is measured at the pile head. It is noted that the piles deform like deflection on a cantilever beam. The maximum bending stress of piles is measured at the soil layer. The pile above the soil layer is subjected to lateral earth pressure due to driving force of the slope, while pile below soil layer is subjected to subgrade reaction against pile deflection. The deflection of piles is increased during cutting slope in front of piles for the construction of soil nailing. As a result of research, the effect and applicability of stabilizing piles in large-scale cut slopes could be confirmed sufficiently.

  • Studies were carried out to elucidate the protein stabilizing effect of ginseng. Malate dehydrogenase (EC 1.1.1.37) was used as a protein and the rate constant of the enzyme inactivation was determined under the heat denaturation condition. There was an optimum pH for the enzyme stability, the rate constant of the enzyme inactivation was minimum at BH 8.8. The rate constant was increased at lower and higher pH regions than the optimum pH. The inactivation reaction followed the Arrehnius law and the activation energy was measured as 36.8kcal/mole. The reaction rate was not affected by the enzyme concentration and thus it was assumed to be unimolecular first order reaction. The water extract of red ginseng decreased the rate constant of Malate dehydrogenate under heat inactivation condition to stabilize the enzyme activity. Purified ginseng saponin also stabilized the enzyme against heat inactivation.

  • A centrifugal compressor was tested with three different diffusers with plate vanes. The vane inlet angle was varied from 15 to 30 dog. The higher static pressure rises are obtained with lower vane stagger angle. In the stable region the static pressure field in vaneless space is very sensitive to flow rate. The impeller has a stabilizing effect over the whole stable operating range. The diffuser has a stabilizing effect at high flow rate but is destabilizing at low flow rate.

  • In this study, changes in chlorophyll and carotenoid pigment in fresh and ash treated Undaria pinnetifida were determined by column chromatography. And pigment stabilizing effects of ashes were discussed. The results obtained are summarized as follows: 1. The main carotenoids of Undaria pinnetifida are fucoxanthin, violaxanthin, lutein and $\beta-carotene$. 2. In storage of fresh Undaria pinnetifida at $2-5^{\circ}C$ for 30 days, chlorophyll a decreased rapidly and mainly converted to pheophytin a. Among carotenoids, lutein was markedly lost while the others retained approximately $30\%$ after 30 days' storage. 3, By treating the sample with ashes, the loss of chlorophyll a was restrained whereas that of carotenoids seemed to be promoted. It is considered that pigment stabilization was attributed to both effect, the pH control effect by the alkalinity of ashes and the fixation of the pigment by heavy metals in ashes. The stabilizing effect of chlorophyll a differed from the kind of ashes used. Reed ashes showed better effect than others such as straw or pine ashes. 4. Since fucoxanthin is extremely sensitive to alkali the treatment of ashes with a high alkalinity resulted in rapid decrease of the pigment during storage. 5. In the analysis of ashes, reed ashes which had better effect on chlorophyll a retention than the other ashes showed the highest content of iron.

  • This study examines the effects on isometric lumbar extension strength, dynamic balance ability, and range of motion, after administering 8 weeks SEBT exercise (dynamic balance exercise) and Lumbar Stabilizing exercise, to open laser lumbar microdiscectomy patients. Totally, 14 patients who underwent preservation treatment for 6 weeks after undergoing open laser lumbar microdiscectomy, were enrolled for the study. Patients were randomly assigned to the Lumbar Stabilizing Exercise Group (LSG, n=7) and SEBT Exercise + Lumbar Stabilizing Exercise Group (SGLS, n=7). Results indicate that isometric lumbar extension strength ratio significantly decreases after 8 weeks rehabilitation exercise in both the LSG (p=0.007) as well as SLSG (p=0.024) groups. Normalized reach distance of the three directions in the Y-balance test to examine the dynamic balance capability showed a significant increase in both groups. The dynamic balance capability showed significant increase to the left (LSG, p=0.010; SLSG, p=0.002) and right (LSG, p=0.002; SLSG, p=0.002). Moreover, significant increase was also obtained in the range of joint operation, in both LSG (p=0.006) and SLSG (p=0.017) groups. These results indicate that both groups of rehabilitation exercise achieve positive outcomes on the isometric lumbar extension strength, range of motion, and dynamic balance ability. However, some results suggest that the SEBT program is likely to have a better efficacy.

  • The purpose of this study was to examine the effect of stabilization of retinyl palmitate (RP) on its skin permeation and distribution profiles. Skin permeation and distribution study were performed using Franz diffusion cells along with rat dorsal skin, and the effect of drug concentration and the addition of pectin on skin deposition profiles of RP was observed. The skin distribution of RP increased in a concentration dependent manner and the formulations containing 0.5 and 1 mg of pectin demonstrated significantly increased RP distributions in the epidermis. Furthermore, it was found that skin distribution of RP could be further improved by combined use of pectin and ascorbyl palmitate (AP), due largely to their anti-oxidative effect. These results clearly demonstrate that the skin deposition properties of RP can be improved by stabilizing RP with pectin. Therefore, it is strongly suggested that pectin could be used in the pharmaceutical and cosmetic formulations as an efficient stabilizing agent and as skin penetration modulator.
