Purpose: The aim of this study was to evaluate the Bonwill triangle of Korean using the cone beam computerized tomography (Cone-beam CT). Materials and Methods: 120 Koreans (60 males and 60 females) who visited Daejeon Dental College Hospital of Wonkwang University and who underwent the Cone-beam CT were selected. The Cone-beam CT images were analysed with Invivo 5.1 (Anatomage, San Jose, USA). After reorientation of axis, the intercondylar distance was measured by clicking both middle points of condyle. And the condyle-incisor distance was measured by clicking the middle point of condyle and contact point of the mandibular central incisor's incisal edge. The collected data were analysed using the SPSS Version 23.0 (IBM Inc., Armonk, USA) and statistical significance was verified by gender using independent t-test. Results: The mean intercondylar distance of Korean was 105.9 mm, and the male (108.3 mm) was statistically significantly larger than the female (103.4 mm). The mean condyle-incisor distance of Korean was 105.2 mm, and the male (108.1 mm) was statistically significantly larger than the female (102.3 mm). Conclusion: The mean intercondylar distance of Korean in this study was 105.9 mm that was smaller than well-known 110 mm of Caucasian and the male was statistically significantly larger than the female. Within the limitations of this study, it would be necessary to use the articulator which can adjust the intercondylar distance according to the individual for prosthodontic treatment of Korean.

Over the last 30 years, the use of chairside computer-aided design (CAD) and computer-aided manufacturing (CAM) systems has evolved and has become increasingly popular in dentistry. Although CAD/CAM restorations have been used in the anterior dentition, satisfying the esthetic requirements of clinicians and patients, where the restorations are limited to the chairside, remains a challenge. To reproduce multi-shades of CAD/CAM restorations in the clinic, a preliminary experiment to express several shades on A2 lithium disilicate (LS2) blocks using a staining kit was performed. After measurement of the CIE L*a*b* value of specimens, it was compared with that of the commercial shade guide. This report presents two cases with individual customization of shade and surface characterization of the CAD/CAM restorations using predictable methods based on the preliminary experimental data. The anatomical shape of restoration was obtained from 'copy and paste technique' and 'mirror image acquisition technique'. All treatment procedures and fabrication of restorations performed in this report were executed in the clinic itself.
The purpose of this study was to collect and analyze information on the major scoring paths, success rate by shooting type, assist, steal, block, and goalkeeper defense rate by shooting type in the 2019 World Women's Handball Championship. Based on the research results, the following conclusions were drawn. First, as a result of the analysis of the scoring route, 1st the Netherlands and 2nd Spain had 6m shots and 7m shots the most. Second, in the success rate analysis results by shooting type, the top 6 teams showed 7m shot, breakthrough shot, and fast shot. Third, according to the result of assist frequency analysis, the fourth place in the competition Norway scored the most assists among the six teams. Fourth, as a result of the steel frequency analysis, Norway scored the most with 5.2 on average among the six teams. Fifth, as a result of analyzing the goalkeeper defense rate by shooting type, it was found that all 6 team's goalkeepers had the highest defense against 9m shooting. Therefore, for an in-depth analysis of the game strategy, it is considered that it is necessary to understand the characteristics of individual player's performance and collect information will be followed by a follow up research in the future.
Purpose : We aim to identify the clinical and demographic characteristics in children who underwent renal transplantation(RTx) and to evaluate the influence on growth of RTx in children. Methods : We reviewed 17 medical records of chronic renal failure patients who underwent RTx from April 1992 and June 2004 at Busan Paik Hospital. Age and sex distribution, cause of disease, donor analysis, patient and graft survival rate, and the status of growth after RTx were analysed by retrospective study. Results : Eighteen RTx were performed in 17 patients(8 boys, 9 girls). The mean age at the time of RTx was $15.8{\pm}3.5$ years and the mean duration of dialysis therapy before RTx was $22.4{\pm}18.0$ months. The 1 year and 5 year patient survival rate were each 100%, and the 1 year and 5 year graft survival rate were 88%, 36% respectively. The most common cause of graft failure was chronic rejection. The mean final height of male patients was $162.8{\pm}10.0$ cm(143.0-172.5 cm) and of female patients was $154.5{\pm}12.1$ cm(135.8-160.0 cm). The mean height standard deviation score(Ht SDS) increased after RTx from -1.95 to -1.53 but the increment rate was not statistically significant. Similar changes were noted in individual patient analysis. Also there was no significant difference between the living-related donors and cadaveric donors. Conclusion : Our data shows that even successful RTx rarely results in full growth rehabilitation. To overcome retarded growth in children with chronic renal failure, appropriate combined management of metabolic and nutritional problems, correction of anemia, proper use of recombinant growth hormone therapy, early renal transplantation and shortening of the duration of dialysis would be necessary.

To increase the acceptance of multicultural youth, it is necessary to grasp the factors influencing multicultural acceptance. This study was conducted to provide basic data for a future study for the promotion of multicultural acceptance of adolescents by systematically analyzing research trends in factors affecting the multicultural acceptance of Korean adolescents. From 2008 to 2017, we searched 6,435 papers combining the keywords 'multicultural,' 'acceptability,' 'teenager,' 'middle school' and 'high school,' and analyzed six articles. The qualitative evaluation refers to Community Guide and STrengthening the Reporting of OBservational studies in Epidemiology(STROBE). The results revealed that factors influencing multicultural acceptance include gender, experience of overseas visits, life satisfaction, parental neglect and abuse, parent education, school and community factors, and community awareness. Multicultural acceptance of adolescents in Korea was influenced not only by specific factors, but also by various factors such as individual, family, school, and community. These factors were also found to change with age. Based on the results of this study, it is necessary to provide an environment and education that promote multicultural acceptance.

This study assessed female occupational therapist job stress and musculoskeletal pain, and examines the problems caused by sexual harassment, family, and marriage policy. The results provide information to improve work environments, reduce job stress, yield data needed for sexual harassment prevention education, examine women occupational therapists' economic activities, and broadly improve the quality of life through participation. The study subjects were currently employed female occupational therapists. Initially 200 subjects were recruited, of whom 185 returned the study questionnaire. Questions addressing job stress included, 'There are times when one feels that the salary is worth less than the job effort', 'Feel tired due to work.', 'That it is time to pay attention to other therapy.', answered positively in that order. Musculoskeletal pain in the wrist and hand (90%), shoulder (86%), neck (69.7%) and waist (68.6%) were the order of the wrist and hand (63%), shoulder (62.2%) and waist (51.9%) pain resulted in interference with daily life. Verbal harassment was reported by 71.4% and 48.6% reported physical and visual harassment. The most common topics in workplace relations were 'Must choose whether to focus on the individual or work (61.1%).', 'Need for understanding and someone who can share their feelings (54.6%).', and 'Colleagues are willing to listen to my story (73%)'.
Various accidents and injuries are currently occurring in Korea at increasingly high rates. Good quality emergency care service is urgently needed to cope with these various forms of accidents and injuries. In order to develop a sound emergency care system, there need to be a plan to educate and train professionals specifically in emergency care. One solution for the on going problem would be to educate and train emergency clinical nurse specialists. This study on a strategy for curriculum development for emergency clinical nurse specialist was based on the following five content areas, developed from literature related to the curriculum of emergency nursing and emergency care situation : 1. Nurses working in the emergency rooms of three university hospitals were analyzed for six days to identify categories of nursing activities. 2. Two hundreds and eleven nurses working in the emergency rooms of 12 university hospitals were surveyed to identify needs for educational content that should be included in a curriculum for the clinical nurse specialist. 3. Examination of the environment in which emergency management was provided. 4. Identification of characteristics of patients in the emergency room. 5. The role of emergency clinical nurse specialist was identified through literature, recent data, and research materials. The following curriculum was formulated using the above mentioned process. 1. The philosophy of education for emergency clinical nurse specialist was established through a realistic philosophical framework. In this frame, client, environment, health, nursing, and learning have been defined. 2. The purpose of education is framed on individual development, social structure, nursing process and responsibility along with the role and function of the emergency clinical nurse specialist. 3. The central theme was based on human, environment, health and nursing. 4. The elements of structure in the curriculum content were divided to include two major threads, I, e., vertical and horizontal : The vertical thread to consist of the client, life cycle, education, research, leadership and consultation, and the horizontal thread to consist of level of nursing (prevention to rehabilitation), and health to illness based on the health care system developed by Betty Neuman system model. 5. Behavioral objectives for education were structured according to the emergency clinical nurse specialist role and function as a master degree prepared in various emergency settings. 6. The content of the curriculum consisted of three core courses(9 credits), five major courses(15 credits), six elective courses(12 credits) and six prerequisite courses (12 credits). Thus 48 credits are required. Recommendations : 1. To promote tile quality of the emergency care system, the number of emergency professionals, has to be expanded. Further the role and function of the emergency clinical nurse specialist needs to be specified in both the medical law and the Nursing Practice Act. 2. In order to upgrade the qualification of emergency clinical nurse specialists, the course should be given as part of the graduate Program. 3. Certification should be issued through the Korean Nurses Association.

When restoring endodontically treated teeth is the mismatch between fiber post size and post space diameter, the resin cement layer is excessively thick in post space and voids are likely to form in it, thus predisposing to de-bonding. The method to overcome this problem is to reline the fiber post with composite resin. This individual anatomic post improves the adaptation of post to root walls and decreases the resin cement thickness. The purpose of this in vivo study was to evaluate the push-out bond strength of fiber post according to relining procedure and luting agents type used for simplicity of clinical procedure. Forty-two extracted teeth were divides into six groups.(n=7) A1: relined fiber post cemented with Luxacore/all-bons 2, A2: non-relined fiber post cemented with Luxacore/all-bond2, B1: relinind fiber post cemented with Calibra/XP-bond, B2: non-relined fiber post cemented with Calibra/XP-bond, C1: relined fiber post cemented with RelyX Unicem, C2: non-relined fiber post cemented with RelyX Unicem Push-out bond strength was affected by interaction between relining procedure and luting agent type. Relined fiber post presented higher push-out bond strength value than non-relined fiber post and statically significant differences(p<0.05) Cementation with RelyX Unicem showed significantly higher bond strength than other luting agents(p<0.05).
Complete denture prosthodontics includes replacement of natural teeth and associated maxillary and mandibular structures for full edentulous patients. The final objectives of prosthodontic treatment include esthetic and functional rehabilitation. Because the esthetic demand of senior patients has increased esthetic requirement should not be overlooked in denture treatment. In complete denture treatment, attempts have been made to reproduce tooth wear, arrangement, recession of cervical gingiva, staining, improved gingival shade and so on. This 61 year old female patient came to the Department of Prosthodontics with the chief complaint that dentures made 5 years ago in a local clinic were broken and did not fit well. The patient put more emphasis on fabrication of natural and esthetic dentures than recovery of masticatory function. Remake of maxillary complete denture and mandibular implant retained overdenture was planned. In order to create esthetic and natural contour, Aesthetic Color Set Easy system$^{(R)}$ (Candulor dental GmbH, Wangen, Germany) was used to make complete dentures reproducing various gingival shades. Patient's esthetic satisfaction was high. When complete denture prosthodontics treatment involves appropriate expression of individual characteristics in addition to proper selection of esthetic materials, treatment will give satisfaction to both dentist and patient.
