Purpose: A variety of short Exeter stems designed specifically for use in performance of total hip arthroplasty (THA) in primary and revision settings have recently been introduced. Some have been used 'off label' for hip reconstruction. The aim of this study is to report clinical and radiological results from the Exeter V40 125 mm stem in performance of primary THA and revision THA. Materials and Methods: This study had a retrospective design. Insertion of 58 (24 primary, 34 revision) Exeter V40 125 mm stems was performed between 2015 and 2017. The minimum follow-up period was two years. Assessment of the Oxford hip score (OHS), EuroQol-5 Dimension (EQ-5D), and radiological follow-up was performed at one and two years. Results: In the primary group, the preoperative, mean OHS was 13.29. The mean OHS was 32.86 and 23.39 at one-year and two-year post-surgery, respectively. The mean EQ-5D-3L scores were at 0.14, 0.59, and 0.35, preoperatively, at one-year follow-up and two-year follow-up, respectively. In the revision group, the mean preoperative OHS was 19.41. The mean OHS was 30.55 and 26.05 at one-year and two-year post-surgery, respectively. The mean EQ-5D-3L scores were 0.33, 0.61, and 0.48 preoperatively, at one-year follow-up and two-year follow-up, respectively. No progressive or new radiolucent lines were observed around any stem at the time of the final follow-up in all patients in both groups. Conclusion: Encouraging results regarding use of Exeter V40 125 mm stems have been reported up to two years following surgery in primary and revision THA settings.

This study proposes a model curriculum for Vocational Home Economics High School in the 7th Curriculum Revision. The model in the study is first drawn from the assumptions that reflect ever changing demands of industrial society for Home Economics education. Another perspective employed in the study is historical analysis that focuses on the evolution of the Vocational Home Economics Curricula from the 1st through the 6th revision. This study also employes comparative research tools for the national level comparison such as USA, Japan, Taiwan, and Korea. The proposed model curriculum in this study is concluded from those step-by-step studies as follows：1) Problem definition and design in current curriculum for Vocational Home Economics high school； 2) Needs and roles analysis of Vocational Home Economics high school for the future； and 3)Historical analysis of our curriculum revisions in the past and coparative analysis with other countries. Authors conducted this research project for 3 month period from June 15, 1996 to September 15, 1996. During this period, authors collected the data and information through those method as an extensive literature review, survey and interview, and curriculum specialist conference. The key and critical features of the proposed curriculum in the study are as follows：1) In the numbers of department, a proposed model curriculum offers 8 as opposed to 6 in the 6th revision, reflecting two additional departments of “Elderly Welfare”and “Cosmotology”. 2) In the statement of educational objectives, a model curriculum emphasizes a more concrete statement to each specific skills according to the changing societal needs. 3) In the numbers of total subject matters, there would be 40 in the new as opposed to 23 in the current curriculum. Among these changes, 17 would occurr in the newly introduced subject matters, while 11 would simply change the subject matter name. Among 40 subject matter, “Introduction to Computer” and “Home Economics in Vocational Education”would be required subject matter. 4) In the total numbers of required unit for graduation in three years, a model offers 86∼132 unit. A maximum unit for each subject matter would be 12.

Purpose: The number of obese patients seeking total hip arthroplasty (THA) continues to expand despite body mass index (BMI) cutoffs. We sought to determine the outcomes of THA in the morbidly obese patient, and hypothesized they would have comparable outcomes to two cohorts of obese, and normal weight patients. Materials and Methods: THA performed on morbidly obese patients (BMI >40 kg/m²) at a single academic center from 2010 until 2020 were retrospectively reviewed. Eighty morbidly obese patients were identified, and matched in a 1:3:3 ratio to control cohorts with BMI 30-40 kg/m² and BMI <30 kg/m². Acute postoperative outcomes and BMI change after surgery were evaluated for clinical significance with univariate and regression analyses. Cox proportional hazard ratio was calculated to evaluate prosthetic joint infection (PJI) and revision surgery through follow-up. Mean follow-up was 3.9 years. Results: In the acute postoperative period, morbidly obese patients trended towards increased hospital length of stay, facility discharge and 90-day hospital returns. At final follow-up, a higher percentage of morbidly obese patients had clinically significant (>5%) BMI loss; however, this was not significant. Cox hazard ratio with BMI <30 kg/m² as a reference demonstrated no significant difference in survival to PJI and all-cause revision in the morbidly obese cohort. Conclusion: Morbidly obese patients (BMI >40 kg/m²) require increased resource expenditure in the acute postoperative period. However, they are not inferior to the control cohorts (BMI <30 kg/m², BMI 30-40 kg/m²) in terms of PJI or all-cause revisions at mid-term follow-up.

The UCP is an authoritative compilation of the customs and practice of letters of credit observed by most of the participants in the transaction. It remains the most successful set of private rules for trade ever developed. First issued in 1933, the UCP has been through five revisions, the latest being the present UCP 500, which came into force in 1994. Since 1994, new developments in transport, insurance, electronic commerce and banking industry have spurred the current revision of the rules. The ICC Banking Commission approved UCP 600 on October 25, 2006 by a unanimous vote of 91 to 0. The revision, which will come into effect on July 1, 2007, incorporates a number of changes from UCP 500 as follows : UCP 600 has a leaner set of rules, with 39 articles rather than 49 articles of UCP 500; New sections on "definitions" and "interpretations" have been added to clarify the meaning of ambiguous terms; The phrase "reasonable time" for acceptance or refusal of documents has been replaced by a firm period of five banking days; UCP 600 allows for the discounting of deferred payment credits. However, UCP 600 has two main problems such as the inconsistency with insurance industry and the banking community-oriented rules. We have some months before the commencement of UCP 600. From today to the commencement of UCP 600, we should study the full contents of UCP 600 and the influences on the trade industry.

This study was to analyze the research trend related to mathematics education evaluation in the analysis of the articles on , . The study explores the future direction of mathematics education assessment research by investigating whether such evaluation was suitable for the expectation about the assessment required in the current mathematics curriculum. This study was to classify the evaluation-related researches based on Korea educational curriculum revision from 1991-2010 to examine the research trend on the mathematics education evaluation in each season in Korea, analyze the articles by 'monitoring of student's progress', 'judgement on instruction', 'giving the value on mathematics achievement of students', 'value judgement of the program' that were the purpose of evaluation presented in 1995 NCTM(National Council of Teachers of Mathematics). As a result, looking at the research trend classified by the time of the educational curriculum revision, the 7th educational curriculum had the most number of the papers announced from 1997-2006. Despite 2007 educational curriculum revision was the short period from announced 2007-2008 before the next educational curriculum was placed, 11 papers(34.4%) were published. According to the category by the purpose of the assessment prescribed in NCTM, it showed that researches of 'monitoring of student's progress(46.9%)' were the most, those of 'value judgement of the program' and 'giving the value on mathematics achievement of students had a similar percentage.

At a time when the direction of the middle and high school curriculum is being discussed in line with the change in the future education paradigm to the 4th industrial revolution and the post-COVID-19 era, this study attempted to establish the identity of middle and high school clothing life education by exploring the clothing life contents with content analysis method and analyzing the 'clothing life industry' related educational content of the curriculum revision period. Following the revision of the curriculum, the contents related to the middle and high school 'clothing life industry' were not systematic. In the 2022 revised curriculum, the 'clothing life industry' and the digital fashion industry are presented as content related to the 'clothing life industry', so it is expected that the textbooks implemented in the educational field in the future will mention specific content about this. In addition, research on the direction of sustainable clothing life is also needed because the 'clothing life industry' can be an important cause of environmental pollution from production to consumption. Above all, it is expected that follow-up studies will be conducted to enhance the value of clothing life education in the future in the reality that the awareness of middle and high school clothing life education is low.

Objectives : This research was investigated to evaluate the psychological characteristics and changes of psychological state among dental orthodontic patients. Methods : This cross-sectional questionnaire research was conducted with 230 dental orthodontic patients in Busan from December 23, 2009 to March 6, 2010. The psychological analysis of dental orthodontic treatment patients was performed with Symptom checklist-90-revision(SCL-90-R) considering 5 general characteristics and 2 treatment period related characteristics. Estimated psychological results were changed T-score. Data analysis was performed with descriptive analysis, t-test and ANOVA using SAS(ver 9.1) program. Results : The levels of T-score of SCL-90-R were $43.88{\pm}7.50$ in hostility(HOS), $43.38{\pm}4.64$ in phobic anxiety(PHOB), $43.20{\pm}6.24$ in somatization(SOM), $42.13{\pm}6.71$ in paranoid ideation(PAR), $41.39{\pm}8.16$ in interpersonal sensitive(I-S), $41.01{\pm}7.90$ in obsessive-compulsive(O-C), $40.96{\pm}5.37$ in psychoticism(PSY), $40.96{\pm}5.19$ in anxiety(ANX) and $39.81{\pm}6.80$ in depression(DEP), respectively. The T-score of phobic anxiety in before treatment group was higher than that of treatment groups. The T-score of interpersonal sensitive and paranoid ideation in over 36 months treatment period group were higher than that of other treatment period groups. Conclusions : Phobic anxiety(PHOB), interpersonal sensitive(I-S) and paranoid ideation(PAR) were affected in pre-treatment and long-term treatment dental orthodontic patients. Psychological management methods considering treatment period are needed to improve mental health of dental orthodontic patients.

Up to the present, ISO 9000 series have contributed which construction of quality management system and improvement of quality competition. Therefore many enterprises have taken an increasing interest in ISO 9000 series and the number certification of it is on the increase every year. In these processes, the side effect has come out. It is of no use to competitive power of enterprise. Because they made an effort for certification without preparation for a short period or there was no continuous system control. In this paper, We review the weakness of existing ISO 9000 series, which have soon ahead of revision. In addition, We propose the considering items or contents in revision for enterprise competition power.

Background: The outcomes of patients 50-55 years old or younger undergoing prosthetic shoulder arthroplasty (PSA) may not generalize to younger patients. We report outcomes following PSA in a consecutive series of patients 40 years or younger. We hypothesize that total shoulder arthroplasty (TSA) provides better outcome and durability than resurfacing hemiarthroplasty (RHA). Methods: Patients were stratified by diagnosis and surgical procedure performed, RHA or TSA. Active range of motion and self-assessed outcome were evaluated preoperatively and at final follow-up. Results: Twenty-nine consecutive PSAs were identified in 26 patients, comprising 9 TSAs and 20 RHAs, with a minimum of 2-year follow-up. Twelve PSAs were performed for chondrolysis. Mean active forward elevation, abduction, external rotation, and internal rotation improved significantly (p<0.001 for all). Mean pain score improved from 6.3 to 2.1, Simple Shoulder Test from 4.0 to 9.0, and American Shoulder and Elbow Surgeons score from 38 to 75 (p<0.001 for all). Patients undergoing RHA and TSA had similar outcomes; but three RHAs required revision, two of these within 4 years of implantation. Four of five patients undergoing revision during the study period had an original diagnosis of chondrolysis. Conclusions: PSA in young patients provides substantial improvement in active range of motion and patient reported outcomes irrespective of diagnosis and glenoid management. However, patients undergoing RHA, especially for chondrolysis, frequently require subsequent revision surgery, so that RHA should be considered with caution in young patients and only after shared decision-making and counsel on the risk of early revision to TSA.

Objective : The goal of this study was to analyze the clinical outcomes of endoscopic third ventriculostomy (ETV) and endoscopic septostomy when shunt malfunction occurs in a patient who has previously undergone placement of a ventriculoperitoneal shunt. Methods : From 2001 to 2020 at Seoul National University Children's Hospital, patients who underwent ETV or endoscopic septostomy for shunt malfunction were retrospectively analyzed. Initial diagnosis (etiology of hydrocephalus), age at first shunt insertion, age at endoscopic procedure, magnetic resonance or computed tomography image, subsequent shunting data, and follow-up period were included. Results : Thirty-six patients were included in this retrospective study. Twenty-nine patients, 18 males and 11 females, with shunt malfunction underwent ETV. At the time of shunting, the age ranged from 1 day to 15.4 years (mean, 2.4 years). The mean age at the time of ETV was 13.1 years (range, 0.7 to 29.6 years). Nineteen patients remained shunt revision free. The 5-year shunt revision-free survival rate was 69% (95% confidence interval [CI], 0.54-0.88). Seven patients, three males and four females, with shunt malfunction underwent endoscopic septostomy. At the time of shunting, the age ranged from 0.2 to 12 years (mean, 3.9 years). The mean age at the time of endoscopic septostomy was 11.9 years (range, 0.5 to 29.5 years). Four patients remained free of shunt revision or addition. The 5-year shunt revision-free survival rate was 57% (95% CI, 0.3-1.0). There were no complications associated with the endoscopic procedures. Conclusion : The results of our study demonstrate that ETV or endoscopic septostomy can be effective and safe in patients with shunt malfunction.
