  • Intra-alveolar transverse crown & root fx. provokes many problems in treatment. Conventionally, extraction of the injured tooth and its prosthodontic restoration has been the treatment of choice. Though orthodontic extrusion could be an alternative treatment, there would be a situation it's inadequate to apply. Loss of natural tooth would be a psychological damage to the patient, of course. This report describes a replantation method of tooth in case of intra-alveolar transverse crown & root fracture. The fractured tooth was extracted, rotated, then replanted. Fixation and esthetic restoration was done. And then endodontic treatment was followed. Continuing follow-up of its function and endodontic status is required.

  • A blast furnace slag(BFS) has been used as a filter medium for the treatment of domestic waste waters during the period of 9-month. More than 90% of phosphorus was removed while the hardness of the treated water increased by 5 times and the pH was significantly raised from 6.8 to 10.8. The high hardness and pH of the treated water indicated dissolution of BSF by the sewage. The experimental results suggest that BFS could be utilized for the removal of phosphorus in the waste water treatment plant using aquatic plants and gravels.

  • The production of high quality seedlings is a very important phase in silvicultural systems for successful reforestation or restoration. The purpose of this study was to measure both growth performances and nutrient responses of Fraxinus rhynchophylla and Pinus densiflora seedlings, which are commercially planted in Korea, according to soil improvement treatments. We applied 8 types of soil improvements: control with no treatment, compost B and compost Y as organic materials, vermiculite, perlite, two level of zeolite, and mix of vermiculite, perlite, and zeolite as inorganic materials in a permanent national nursery. Only compost B treatment significantly increased soil pH, organic matter, total nitrogen, available phosphorus, exchangeable potassium and calcium at the 0-10 cm soil depth. The growth of F. rhynchophylla and P. densiflora was the highest at the compost B treatment and the lowest at the vermiculate treatment. Compost B treatment allocated more carbon to aboveground than belowground by 39%, especially to foliage. On the vector diagnosis, there was 'shortage' on compost B treatment because of all increases of N contents, N concentrations, and growth and 'over accumulation' on vermiculite treatment because of more N uptake compared with dry weight increase. This study suggested optimal use of soil improvements is very important to improve soil quality in a permanently used nursery.

  • Background It is known that nonsynostotic plagiocephaly does not spontaneously improve, and the craniofacial deformities that result from it. This study was conducted to analyze the effectiveness of helmet therapy for the nonsynostotic plagiocephaly patient, and to suggest a new treatment strategy based on this analysis. Methods A total of 108 pediatric patients who had undergone helmet therapy after being diagnosed with nonsynostotic plagiocephaly were included in this study. The patients were classified according to the initiation age of the helmet therapy, severity, and helmet wearing time. The treatment effect was compared using cranial vault asymmetry (CVA) and the cranial vault asymmetry index (CVAI), which were obtained from diagonal measurements before and after therapy. Results The discrepancy of CVA and CVAI of all the patients significantly decreased after helmet therapy. According to the initiation time of helmet therapy, the treatment effect was best at 5 months old or less. The helmet wearing time per day was proportional to the treatment effect up to 20 hours. In addition, the rate of the successful treatment (final CVA ${\leq}$ 5 mm) significantly decreased when the initiation age was 9.1 months or older and the treatment period was less than 7.83 months. Conclusions This study showed the effectiveness of the helmet therapy for nonsynostotic plagiocephaly patients. Based on analysis of this study, helmet therapy should be started at the age of 9 months or younger for 7.83 months or more, and the helmet wearing time should be more than 20 hours a day.

  • This text was analyzed and investigated the morphological character, production time and germination characteristic of seed that collect in Chungnam, in order to offer the basic informations for slope restoration and revegetation using Indigofera amblyantha of wild shrub. Legume was cylindrical type and length 31.5mm, width 2.5mm, and seed number of per legume was full ripe 5.5, unripe 0.9. Seed was elliptical type and length 2.4mm, width 1.7mm, and weight of 1,000 seeds was 5.9g. Because seed matured within December and next year January, optimum time of seed production was in mid of January. In the treatment $H_2SO_4$ of 15 minutes, seed germination rate was the highest as 91.0%, and seed germination time (days) was the shortest as 6.7 days. Seed germination time by temperature was the shortest from $25^{\circ}C$. Therefore, seed germination of Indigofera amblyantha was very useful in the treatment $H_2SO_4$ of 15 minutes from $25^{\circ}C$ temperature.

  • Background Reconstruction of ischial pressure sore defects is challenging due to extensive bursas and high recurrence rates. In this study, we simultaneously applied a muscle flap that covered the exposed ischium and large bursa with sufficient muscular volume and a profunda femoris artery perforator fasciocutaneous flap for the management of ischial pressure sores. Methods We retrospectively analyzed data from 14 patients (16 ischial sores) whose ischial defects had been reconstructed using both a profunda femoris artery perforator flap and a muscle flap between January 2006 and February 2014. We compared patient characteristics, operative procedure, and clinical course. Results All flaps survived the entire follow-up period. Seven patients (50%) had a history of surgery at the site of the ischial pressure sore. The mean age of the patients included was 52.8 years (range, 18-85 years). The mean follow-up period was 27.9 months (range, 3-57 months). In two patients, a biceps femoris muscle flap was used, while a gracilis muscle flap was used in the remaining patients. In four cases (25%), wound dehiscence occurred, but healed without further complication after resuturing. Additionally, congestion occurred in one case (6%), but resolved with conservative treatment. Among 16 cases, there was only one (6%) recurrence at 34 months. Conclusions The combination of a profunda femoris artery perforator fasciocutaneous flap and muscle flap for the treatment of ischial pressure sores provided pliability, adequate bulkiness and few long-term complications. Therefore, this may be used as an alternative treatment method for ischial pressure sores.
