  • Legg-Calve-Perthes (LCP) disease is characterized by idiopathic avascular osteonecrosis of the epiphysis of the femur head. The main factor that plays a role in the etiology of the disease is decreased blood flow to the epiphysis. Many predisposing factors have been suggested in the etiology of LCP disease, and most have varying degrees of effects. Here we present the case of a boy aged 4 years and 10 months with complaints of short stature and a diagnosis of multiple hypophyseal hormone deficiency, in whom LCP disease and difficult birth-related pituitary stalk interruption syndrome were identified by anamnesis. The present case revealed that LCP disease and hypophyseal hormone deficiency could be secondary to difficult birth and that LCP disease could be secondary to insulin-like growth factor 1 deficiency. Additionally, to the best of our knowledge there is no published case on the relation between LCP disease and insulin-like growth factor 1 deficiency. Therefore, we believe that this case is worthy of presentation.

  • Purpose: To evaluate and compare the outcome between interlocking IM nailing and LCP fixation in the treatment of distal metaphyseal tibial fracture. Materials and Methods: From January 2000 to December 2007, 17 patient were treated by interlocking IM nail and 13 patient were treated by LCP fixation for distal metaphyseal tibial fracture. Results: According to AO classification, there were 2 type A1 fracture (12%), 6 type A2 fracture (36%), 3 type A3 fracture (18%), 4 type B1 fracture (24%), 1 type B3 fracture (6%), 1 type C1 fracture (6%) in interlocking IM nailing group and 1 type A2 fracture (7.7%), 2 type A3 fracture (15.4%), 3 type B1 fracture (23%), 3 type B2 fracture (23%), 3 type C1 fracture (23%), 1 type C2 fracture (7.7%) in LCP fixation group. The clinical functional outcome (according to AOFAS score) is 75.6 point in IM nailing group and 81.5 point in LCP fixation group. In IM nailing group, 65% of patient showed satisfactory result and In LCP fixation group, 77% of patient showed satisfactory result. Conclusion: There is no difference on clinical results between IM nailing and MIPPO (minimal invasive percutaneous plate osteosynthesis) group in the treatment of distal tibia fracture. But MIPPO group have higher subjective satisfactory score and less complication rate. The weakness of our study is a small case number and limited follow-up and we believe a better designed prospective study will be needed.

  • In a previous study, three larval cuticle protein genes were cloned from the mulberry longicorn beetle, Apriona germari (Comp. Biochem. Physiol. B 136, 803-811, 2003). In the present study, the genomic structures of these three larval cuticle protein genes (AgLCP9.2, AgLCP12.6 and AgLCP12.3) were elucidated. All three cuticle protein genes consist of one intron and two exons. Southern blot analysis of genomic DNA suggested that three cuticle protein genes are a single copy gene. In addition, a novel larval cuticle protein gene, AgLCP10.6, was cloned from A. germari in this study. The AgLCP10.6 cDNA contains an ORF of 300 nucleotides that are capable of encoding a 100-amino acid polypeptide with a predicted molecular mass of 10.6 kDa. The amino acid sequence deduced from the AgLCP10.6 cDNA contained a type-specific consensus sequence identifiable in other insect cuticle proteins and is most homologous to Drosophila melanogaster cuticle protein ACP65A (51 % protein sequence identity). Northern blot analysis revealed that AgLCP10.6 showed epidermis-specific expression.

  • The effect of soybean meal and barley supplementation of the utilization of rice straw was investigated. Balance trials were conducted with three Japanese Corriedale wethers fed rice straw supplemented with soybean meal and barley at three different levels of protein: low (40 g CP/d, LCP), medium (67 g/d, MCP) and high (94 g/d, HCP). In addition, all the supplements were formulated to contain the same amount of TDN (275 g/d). Voluntary intake of rice straw was not affected by any supplementation, while digestibility of organic matter in sheep given HCO diet was significantly higher (p<0.05) than those on LCP diet. Crude protein, neutral detergent fiber (NDF) and acid detergent fiber (ADF) digestibilities of MCP and HCP diets were significantly improved (p<0.05) over the LCP diet. Average daily gain of the animals under MCP and HCP diets were significantly higher (p<0.05) than those under LCP diet. Differences of rumen pH among the treatments were not significant, while concentration of rumen $NH_3-N$ was significantly higher (p<0.05) for HCP diet than for LCP and MCP diets. Total volatile fatty acids ($VFA_s$) and blood urea nitrogen (BUN) concentrations were significantly higher (p<0.05) in sheep fed MCP and HCP diets than those fed LCP diet, while plasma total protein concentration was not affected by any supplementation. Sheep fed MCP diet had a higher nitrogen retention than those fed LCP and HCP diets. It was concluded that rice straw was utilized better by sheep when SBM and barley were supplemented at the medium level of protein.

  • A cuticle protein gene, PbLCP12.1, from the white­spotted flower chafer, Protaetia brevitarsis, was isolated and characterized. The gene contains an ORF of 336 nucleotides capable of encoding a 113 amino acid polypeptide with a predicted molecular mass of 12,138 Da and pI of 4.15. The PbLCP12.1 protein contained a type-specific consensus sequence identifiable in other insect cuticle proteins. The deduced amino acid sequence of the PbLCP12.1 cDNA is most similar to Bombyx mori cuticle protein BmLCP18 (37$\%$ protein sequence identity). Northern blot analysis revealed that PbLCP12.1 showed the epidermis-specific expression.

  • In order to guarantee the compatibility of e-Book viewers based on EPUB 3, IDPF launched Readium SDK v1.0 in January, 2015, which was followed by research on the implementation of Readium LCP specifications for user-friendly DRM functions. The complexity of the Readium SDK, however, makes difficulties in interlocking Readium SDK with LCP modules. Moreover, from the perspective of the Readium SDK, which tries to maintain the architecture, independently of any specific DRM technologies, the strong interlock with LCP, as a one DRM, is not desirable. This study represents a Content Protection Framework Model for compatibility of Readium-SDK-based e-Book DRM in order to hide the complexity of Readium SDK and implement an easy interlock between plural DRM and Readium SDK.

  • This study creates the LCP (Landscape Control Point) through the survey of spot sites for the quality of landscape assessment, which is based on an objective and departmentalized data base; the landscape assessment was achieved by production of weight value with the AHP (Analytic Hierarchy Process) technique, selection of requisites for the landscape assessment with the IVERSON method and visual area analysis with GIS (Geographic Information System). Futhermore, validity of the landscape assessment was verified by analysis of the correlation between physical amount and aesthetic amount. The purpose of this study is to suggest the basic essential data for landscape assessment and landscape planning by the characteristics of landscape based on verification of the suggested landscape assessment methods. The results of this study are summarized below. 1. In the adaptation of landscape assessment using GIS, the landscape assessment points of LCP 18, 17 and 16, which have more visible elements such as hill area, mountain area, and forest and farm land, were indicated to be higher than the others. In contrast, the landscape assessment points of LCP 13, 6 and 10, which have less visible elements, were relatively lower than the others. 2. In the visible preference measuring method, LCP 4, 14, and 16 showed high points of landscape assessment with 3.46, 3.4, and 3.18 each. With the more natural environments such as hill area, mountain area, and forest and farm land, higher results were shown. In contrast, LCP 7, 1, and 9 showed low points of landscape assessment with 2.24, 2.36, and 2.53 each. 3. In this study, a coefficient of 0.746 was gained by the analysis of correlation between the points of landscape assessment method and the points of visual preference from a slide show. This has 99 percent of probability in statistical data. 4. In conclusion, with the demonstration of the correlation between the landscape assessment method based on the AHP technique and the aesthetic amount (preference proportion), the practical use of landscape assessment can be demonstrated by the suggested landscape assessment method.

  • We investigated mechanical, rheological and electrical properties of graphite/PP/LCP composites for a bipolar plate of the polymer electrolyte membrane fuel cell. The composites containing very low molecular weighted PP showed much higher electrical conductivity compared with other thermoplastics. This was attributed to the enhanced dispersion of graphite particles due to the low viscosity of the PP. The conductivity of the composites was increased in a great extent by incorporation of small amount of carbon nano tube (CNT). However, the acid treated CNT which contains oxygen atoms did not increase the conductivity of the composite. From this result, it is concluded that the CNT has higher affinity with non polar polymer. The composite with low molecular weighted PP provided good processability so that the composites can be processed by an injection molding while the mechanical strength is deficient compared to other polymers. In order to reinforce the low mechanical property, LCP/PP was used as a binder and the graphite/PP/LCP composite showed the higher conductivity and moderate mechanical strength maintaining suitable processability.

  • Purpose: To assess the effectiveness of the Locking compression plate (LCP) after open reduction for the treatment of the displaced clavicular shaft fracture, the clinical and radiologic outcome of the patients who were managed with the LCP for internal fixation after open reduction has been analyzed. Materials and Methods: We reviewed 26 cases with a displaced clavicular shaft fracture treated by internal fixation using Locking compression plate after open reduction between May 2003 and November 2004. The patients were followed up for at least six months period, and final postoperative outcome was evaluated using clinical results based on Kang's criteria, radiologic signs of fusion. Results: All fractures united by an average of 9.3 weeks without delayed union and showed fast recovery of motion fraction and shoulder function. In addition,24 cases without the fractures of proximal humerus recovered to normal range of shoulder notion within 2.9 weeks. Clinically, according to Kang's criteria, the outcome was good or better in 22 patients. The complications included shoulder joint dysfunction in two cases and keloid formation in one case, and no other complications were observed. Conclusion: The internal fixation using LCP for the treatment of displaced clavicular shaft fracture is a safe, reliable method of treatment, with few complications, and offers rapid recovery of shoulder joint function and bone union.
