Purpose: Congenital upper eyelid defect is rare anomaly whether it is compared with syndromic anomaly or not. It has many clinical manifestation in the extent, location. Many operation procedures such as simple closure, semicircular rotation flap, Cutler Beard procedure, lower lid rotation flap, etc can be used to reconstruct eyelid defects. We intend to introduce a simple, congenital eyelid defect which was not compared with syndromical anomaly, ophthalmic complication. Methods: Our experience is a case of 19 years old female who had a upper eyelid coloboma without any other anomalies. we could not find any skeletal deformity in orbital CT scan. she had no ophthalmic problem. we reconstructed the defect with bilateral marginal flap after deepithelization of supramarginal area and tarsal reposition. Results: There were no visible deformity of lid lining. postoperative scar was favorable. satisfactory results were obtained in cosmetic and functional aspects. Conclusion: Upper lid coloboma without other anomalies is rare. we obtained satisfactory outcome as treated this rare case with marginal flap advancement.

Cupid's bow, upper lip, columella, and ala of nose are esthetically important, in which their symmetrical plasties determine success or failure of the surgery in cleft lip and palate patients. Z-palsty and its modifications are simple and effective. The double Z-plasty is economical in surgical time and esthetics in reconstructing the cupid's bow compared with other methods. We report a 29-year-old male patient who represented reversed cupid's bow and whistle deformity after the primary repair of the cleft lip. He was corrected the cupid's bow using a double Z-plasty. The reversed cupid's bow was corrected to a normal shape and the whistle deformity disappeared. The tightness of the upper lip was relieved after the operation. The double Z-plasty was esthetically successful because the procedure was limited in the vermilion and did not produce a new scar on the skin. Furthermore, the lip tubercle became protuberant. The cupid's bow was symmetrically smoothly curved at 4 years after the operation. These results indicate that the double Z-plasty is simple, less traumatic to the surrounding tissues, and suitable for the correction of whistle deformity.

Growing demand for smart phones and data communication diminishes the constraints of Twitter and Facebook than a smartphone has become a subject of interest. On the other hand facebook users in their relationships to obtain the consent of the other, twitter is a relatively simple procedure for the information ripple effect is excellent. Twitter is beyond a simple social networking services(SNS) located in one of the popular media and powerful have the upper retweet. Retweet to the top of his sympathy with the ability th send tweets to their subscriber information can spread quickly. In this paper, we propose the smart retweet that system actively extend the existing retweet. In order to realize the smart retweet and additional criteria for determining the destination of the information is required. Based on tweet generated regional or an local information mentioned to tweet, to determine the destination. Smart retweet of the speed and scope of information transmission through the scale is expected.

Plant seed oil-bodies or oleosomes ate the repository of the neutral lipid stored in seeds. These organelles in many oilseeds may comprise half of the total cellular volume. Oleosomes are surrounded by a half-unit membrane of phospholipid into which are embedded proteins called oleosins. Oleosins are present at high density on the oil-body surface and after storage proteins comprise the most abundant proteins in oilseeds. Oleosins are specifically targeted and anchored to oil-bodies after co-translation on the ER. It has been shown that the amino-acid sequences responsible for this unique targeting reside primarily in the central hydrophobic tore of the oleosin polypeptide. In addition, a signal-like sequence is found near the junction of the hydrophobic domain and ann N-terminal hydrophilic / amphipathic domain. This "signal" which is uncleaved is also essential for correct targeting. Oil-bodies and their associated oleosins may be recovered by floatation centrifugation of aqueous seed extracts. This simple partitioning step results in a dramatic enrichment for oleosins in the oil-body fraction. In the light of these properties, we reasoned that it would be feasible to create fusion proteins on oil-bodies comprising oleosins and an additional valuable protein of pharmaceutical or industrial interest. It was further postulated that if these proteins were displayed on the outer surface of oil-bodies, it would be possible to release them from the purified oil-bodies using chemical or proteolytic cleavage. This could result in a simple means of recovering high-value protein from seeds at a significant (i.e. commercial) scale. This procedure has been successfully reduced to practice for a wide variety of proteins of therapeutic, industrial and food no. The utillity of the method will be discussed using a blood anticoagulant, hirudin, and industrial enzymes as key examples.

Three dogs were presented with diaphyseal fracture of the tibia following separate motor vehicle accidents. On physical and orthopedic examinations, the dogs were noted to have soft-tissue swelling and a closed fracture in these tibia sites. Radiographs revealed a simple, short oblique fracture (case 1), a comminuted, spiral fracture (case 2), and a simple, spiral fracture (case 3) in tibia. Minimally invasive percutaneous plate osteosynthesis (MIPO) using a veterinary cuttable plate or locking plate was applied for the treatment of these fractures. The surgery was successful, and the fractures healed without any complications by 7 weeks (case 1), 10 weeks (case 2) and 8 weeks (case 3) after surgery. Our patients showed fast bone healing times and early weight-bearing during the treatment of their tibia fractures. Therefore, MIPO was a useful procedure for diaphyseal fracture of the tibia in veterinary orthopedics.

Purpose : The aim of this study was to compare surgical complications between simple implant placement and implant placement combined with complicated surgical procedures. We also evaluated prosthetic complications according to the specific types of prosthesis. Material and Method : A retrospective analysis of dental chart of patients who was performed implant therapy during the period from June 2003 to December 2005 was carried out. This study was performed on 408 patients (208 male, 200 female). In addition, 1671 implants were performed. Based on their medical record and radiographs, the authors evaluated surgical and prosthetic complications, surgical procedures accompanied at the time of implant, risk factors of implant failure etc. Result : Surgical complications were developed on 358 implants(21.4% on total placed implants) and wound dehiscence was most prevalent complication. On maxillary posterior area, surgical complications developed more frequently on implants with major surgery and showed a significant difference. And complication rate of implants accompanied with GBR was higher than that of simple implants placement and also showed significant difference. The implant supported prosthesis showed no statistical difference in the occurrence of complications according to the types of prosthesis, and food retention was the most common post-prosthetic complication. Also we speculated that length and width of implant showed significant correlation to the failure of implant primary osseointegration. Conclusion : Based on the result, clinician should provide more careful maintenance for patients with implant placement accompanied by complicated surgical procedure. And periodic maintenance for the patient is requested for long-term survival of implant therapy.

Using beam data and accurate 3D dose model, a study of the spatial dose distribution for various arcs was carried out. The dose dirstibution generated by the accurate dose model could be represented by a simple approximate analytic form which is convenient and very efficient for calculating dose distribution iteratively in the optimization procedure. We developed an empirical cylindrical dose model to compute dose for one full rotational arc or partial rotational arc. After a tedious search for fits to a collection of 200 points of accurate dose data, we found simple formular with 7 parameters search. As a consequence, the programs required approximately less than 1 second to compute dose for one single arc on a 20 by 20 matrix (400 points) using fast approximate dose model. In conclusion the fast approximate dose model give dose distributions similar to the accurate dose model, which makes this fast dose model an attractive alternative to the accurate 3D dose model.

Poly-ADP-ribosylation (PAR) is a post-translational modification of mainly chromosomal proteins. It is known to be strongly involved in several molecular events, including nucleosome-remodelling and carcinogenesis. In this investigation, it was attempted to evaluate PAR level as a reliable biomarker for early detection of cancer in blood lymphocyte histones. PAR of isolated histone proteins was monitored in normal and dimethylnitrosamine (DMN)-exposed mice tissues using a novel ELISA-based immuno-probe assay developed in our laboratory. An inverse relationship was found between the level of PAR and period of DMN exposure in various histone proteins of blood lymphocytes and spleen cells. With the increase in the DMN exposure period, there was reduction in the PAR level of individual histones in both cases. It was also observed that the decrease in the level of PAR of histones resulted in progressive relaxation of genomic DNA, perhaps triggering activation of genes that are involved in initiation of transformation. The observed effect of carcinogen on the PAR of blood lymphocyte histones provided us with a handy tool for monitoring biochemical or physiological status of individuals exposed to carcinogens without obtaining biopsies of cancerous tissues, which involves several medical and ethical issues. Obtaining blood from any patient and separating blood lymphocytes are routine medical practices involving virtually no medical intervention, post-procedure medical care or trauma to a patient. Moreover, the immuno-probe assay is very simple, sensitive, reliable and cost-effective. Therefore, combined with the ease of preparation of blood lymphocytes and the simplicity of the technique, immuno-probe assay of PAR has the potential to be applied for mass screening of cancer. It appears to be a promising step in the ultimate goal of making cancer detection simple, sensitive and reliable in the near future.

A memory access method that data are read with different sequences with writing order is a simple but important procedure in many image compression standards, such as JPEG, MPEG1/2/4, H.264, and HEVC. For real time processing, double buffering is widely used using two block sized buffers, that accesses buffers concurrently with alternative way to read and write. In some cases like a transpose memory in 2D DCT with a simple and regular access order, a single buffering which requires only single block sized buffer can be used. This paper shows that even in complex access orders there is a regularity among updating orders within a finite turns, and suggested an effective implementation method using a single block sized buffer to process concurrent read/write operation with different access orders.

Many old domestic mines were excavated with the room and pillar method or the sublevel caving method and they involve the great possibility of surface subsidence, especially in the shallow depth mines. In most of these cases, the mine roadways and openings are very irregular in shape and the information about the local geology is uncertain. Consequently it is not simple to standardize the estimation method for the possibility of subsidence, especially the sinkhole subsidence. In this study, the fuzzy reasoning method has been applied for development of estimating the possibility of subsidence occurrence in abandoned mine area. This method has the advantage in producing the reliable estimation results with a simple performance procedure even when the precise information on the local geology and mining conditions is rare. For the verification of applicability of this method, the developed method has been applied to Kumho mine in Bonghwa, Kyungbook province and the Choong-ju mine in Iryu, Choongbook province where the surface subsidence occurred already.
