We describe our experience with conservative condylectomy for the correction of facial asymmetry in five patients with osteochondroma of the mandibular condyle. All five patients presented with malocclusion and facial asymmetry, which are common clinical findings of osteochondroma involving the mandibular condyle. We performed conservative condylectomy without additional orthognathic surgery for all five patients, preserving the vertical height of the condylar process as much as possible. Following surgery, intermaxillary traction using a skeletal anchorage system with rubber elastics was performed on all patients to improve occlusion, and, when necessary, additional minimal orthodontic treatment was performed. The mean follow-up period was 42 months. At the last follow-up visit, all patients exhibited satisfactory facial symmetry and remodeling of the remaining condyle, with stable health and no signs of recurrence. In conclusion, conservative condylectomy alone, without subsequent orthognathic surgery, is adequate for the restoration of facial symmetry and the preservation of vertical condylar height in select patients with condylar osteochondroma.

Pentachlorophenol(PCP) which ks widely used in wood preservation, pulp and paper mills, has led to a substantial envirortmental contamination. To get the reliable data for the effective health risk assessment with PCP, covalent binding potential of PCP to cellular macromolecules and glutathione(GSH) was investigated after intraperitoneal administration of $^{14}C-PCP$ to rats. PCP metabolites were able to bind covalently to serum albumin and hepatic protein in a dose- and time-dependent manner. Hepatic protein adducts of PCP metabolites were increased as a function of cytochrome P-450 activities, whereas, albumin adducts significantly decreased. Covalent binding of PCP metabolites with DNA or hemoglobin was not observed. GSH levels in liver tissue decreased over 12hrs, however, the level was recovered after 48hrs. Tetrachloro-1,4-benzoquinone (1,4-TCBQ), one of the most reactive PCP metabolites, conjugated with GSH very rapidly. Base on our results, we could conclude that PCP metabolized to reactive electrophilic metabolites by cytochrome P-450 isoenzymes and conjugated rapidly with neighboring protein or nonprotein sulfhydryl before reacting with DNA or hemoglobin. We propose that albumin adducts and mercapturic acids of PCP metabolites can be used good biomarker of recent PCP exposure.

In this report, we present a rare case of solid silicone implant displacement to the contralateral side after aesthetic gluteal augmentation, a phenomenon that has never been reported before in the literature. A 29-year-old woman with a history of gluteal augmentation 9 months previously and soft tissue infection presented for a consultation due to 3 days of sudden progressive pain in the right gluteus with erythema and edema, without a history of trauma. Displacement of the left gluteal implant to the right gluteal pocket was shown by magnetic resonance imaging. Because the patient refused implant removal, the decision was made to perform capsulotomy, to reconstruct the gluteal pockets, and to preserve the implants. The patient showed a satisfactory early and late postoperative course. Possible causes of this complication include poor surgical technique, with insufficient tissue preservation to keep the pockets apart, and the presence of seroma or hematoma that favored an infectious process, thereby leading to deterioration of the dissected soft tissues with dehiscence of the wound favoring the displacement of the implant.

Purpose : Preservation of the periodontal health of the treated patient requires supportive periodontal therapy for the elimination of periodontal disease. After Phase I therapy is completed, patients are placed on a schedule of periodic recall visits for maintenance care to prevent recurrence of the disease. The amount of tooth loss would be the most relevant criterion in an evaluation of the effect of periodontal treatment, but this would require studies with extremely long follow-up periods. Thus the most commonly used outcome criteria in clinical research have been clinical attachment level change, reduction of pocket depth and bleeding frequency. The purpose of this case study is to identify the effect of supportive periodontal therapy after periodontal flap surgery. Materials & Methods : Following routine hygienic phase of treatment, patients with chronic periodontitis received surgical periodontal treatment. Bleeding on probing, pocket depth and clinical attachment level were measured at baseline, pre-operation and 1 year follow up. All procedures were performed by one operator. Results : One year a total of 28 patients (58sites) to recheck remained, when conducted maintenance program after periodontal flap surgery was observed reduction of bleeding frequency, pocket depth and improvement of clinical attachment level. Conclusion : The results from this study indicate that supportive periodontal therapy after periodontal flap surgery is effective for reduction of bleeding frequency, pocket depth and gain of clinical attachment level.

The purpose of this paper was to investigated to the relationship between longevity and Sasang Constitution. The investigation of this paper is composed of 4 parts. First part is investigated to the distribution of sex constitution and constitutional form. Second part is the distribution of the special of body quality(blood pressure, Pulse, Respiration, heredity, stool frequency) and the disease. Third part is the relation of the longevity reason(diet, alcohol intake, smoking). Fourth part is the relationship between the QSCC II and longevity reason. The results were as follows : 1. In case of a macrobian, Soyangin is much more in constitution. 2. A macrobian is generally short and thin. 3. About the macrobian's strength of heredity, there is no any meaningful conclusion, but more studying relationship between heredity and longevity is needed. 4. A macrobian has normal condition in blood pressure, pulse and feces condition. 5. In case of macrobian, the portion of a light eater, non-smoker, and abstainer is high, they like warm food. 6. A macrobian who is active and diligent has high accomplishment and good sociality. Considering above conclusion, a macrobian is related to Soyangin in characteristic of constitution. In the future, more studying is needed whether the macrobian has kept their lives with their unique preservation of health or not.

The past concept of constructing houses was focused on how to overcome the limitation of consuming natural resources such as energy and materials, which increased the official cost and the environmental pollution. On the other hand, the echo-friendly concept has considered the harmony between human being and nature more critically and has applied the characteristics of natural environment into a unique dwelling design by developing constructs and materials adjusted to the particular climate, making them into a unit of impacting positively the complicated system. The current environmental issue is how a dwelling adapts into a given climate in which the design is applied by ecology without damaging the natural environment. In another word, the main issue in the twenty first century will be how we meet the human needs to dwellings applied by the residential environment. Therefore, we have to provide a hospitable place for residents' mental and physical health through "Green Design", emerging as the critical design of urban collective dwellings. Based on these conceptions, the purpose of this study is to suggest the way of designing the urban collective dwelling applied by ecology, proffering wealthy life style to residents with the preservation of natural environment as applying an ecological concept into the design of collective dwellings that represent a contemporary housing type for urban residents.

In this paper, we propose a privacy-preserving emergency call scheme, called PEC, enabling patients in life-threatening emergencies to fast and accurately transmit emergency data to the nearby helpers via mobile healthcare social networks (MHSNs). Once an emergency happens, the personal digital assistant (PDA) of the patient runs the PEC to collect the emergency data including emergency location, patient health record, as well as patient physiological condition. The PEC then generates an emergency call with the emergency data inside and epidemically disseminates it to every user in the patient's neighborhood. If a physician happens to be nearby, the PEC ensures the time used to notify the physician of the emergency is the shortest. We show via theoretical analysis that the PEC is able to provide fine-grained access control on the emergency data, where the access policy is set by patients themselves. Moreover, the PEC can withstandmultiple types of attacks, such as identity theft attack, forgery attack, and collusion attack. We also devise an effective revocation mechanism to make the revocable PEC (rPEC) resistant to inside attacks. In addition, we demonstrate via simulation that the PEC can significantly reduce the response time of emergency care in MHSNs.

The purpose of this study was to analyse the recognition and preference level associated with the preservation of Korean traditional health food. Self-administered questionnaires were collected from 289 individuals. The data was statistically analysed using I-test as well as the one-way analysis of variance (ANOVA). We studied whether or not respondents had the constitutional cuisine before Ed-comments : Please complete the sentence. Before what?. Twenty-two kinds of Korean traditional foods were randomly selected based on old cookbooks, and then recognition and preference of Korea traditional constitutional cuisine were asked. The tasting experience in the constitutional cuisine affected recognition and preference significantly. The coefficients of recognition and preference were the highest in Junbokjoog ($4.20{\pm}1.00$), Yookgejang ($4.18{\pm}1.03$), Jangagui ($4.05{\pm}1.17$), Origui ($3.97{\pm}1.19$) and Samgeitang ($3.94{\pm}1.15$). Ed-comment : Please check if this value is correct. There are two decimal points. Bosintang ($1.81{\pm}1.60$) showed a low preference compared to high recognition, and was therefore considered to be enthusiasts' cuisine only. It is believed that promoting the greater awareness of Korean traditional constitutional cuisine through the mass media would result in a higher recognition and preference of the same.

It is important to accurately predict structural responses to external excitations such as typhoons and earthquakes when designing structures for serviceability. One of the key procedures to predict reliable vibration responses is to evaluate accurate structural dynamic properties using finite element (FE) models, which properly represent the realistic behavior of buildings. In the case of historic masonry buildings, structural damage could also be caused by ambient vibrations or impacts. Therefore, the preservation plans of historic buildings for low-level vibrations or impacts should be provided by analyzing structural damages within serviceability levels. For this purpose, it is required to provide FE model construction and response analysis methods verified with field measurement data. In this research, long-term field measurement was performed for a cathedral and its dynamic properties were evaluated using measured data. Then, the model was calibrated based on the measured dynamic properties and an overall construction method for the masonry cathedral was proposed. Using the measured accelerations, the vibrations of the belfry were analyzed using the calibrated FE model and finally, the FE model for the cathedral was verified by comparing the measured accelerations with the modeled results.

Objectives : The lawsuits associated with medical practice in Korean medicine are increasing gradually. However, the clear definition for medical practice in Korean medicine has not been existed in Korean law. Only we may understand the concept regulated by judicial precedents of the court of justice or the authoritative interpretation by the government. Methods : For study, a database was established for medical lawsuits involving Korean medicine(1968~2009, n=130). Results : According to court rulings, the medical practice in Korean medicine is an act to diagnose a person's illness, prescribe and treat to cure based on traditional Korean medicine, to be understood as a medical care, to have some factor to create or increase danger for the preservation of health or hygiene, and to be practiced by medical specialists based on their professional knowledge. Conclusions : But, such definition is not proper and exceedingly vague. Besides medical circumstances Koreans Medicine are changing, and new precedent to the definition of the practice of medicine is establishing. Therefore the meaning and scope of the medical practice in Korean medicine should be modified and amended, reflecting these conditions.
