Purpose: Post-burn pruritus is one of the most prevalent complications experienced by burn patients. Though medications are prescribed for pruritus, managing this condition can prove challenging. The aim of this research was to develop and disseminate non-pharmacological self-management educational resources, and subsequently evaluate the effectiveness of implementing a percussion therapy approach. Methods: A one-group pretest-posttest design was employed to evaluate the effect of percussion therapy on one hundred patients, all of whom had suffered deep second-degree burns and undergone skin graft surgery. Variables such as the severity of pruritus, distress caused by pruritus, and satisfaction with pruritus treatment were scrutinized. A paired t-test was conducted to compare these variables before and after the intervention. Results: The majority of participants were diagnosed with third-degree burns, and the average Total Body Surface Area (TBSA) affected was 25.2%. Post-test results revealed a marked reduction in both severity and distress caused by pruritus. The intervention led to significant decreases in average severity and pain due to itchiness, and an increase in the satisfaction level following the application of percussion therapy. Conclusions: The implementation of the percussion was identified as effective in diminishing post-burn pruritus, alleviating pruritus-associated pain, and enhancing satisfaction with pruritus treatment. The percussion approach presents itself as a non-invasive, non-pharmacological strategy for managing pruritus in burn patients.

데이터 웨어하우징(Data Warehousing, DW) 개념이 탄생한 1970년대는 미국 유통 대기업 월마트가 폭증한 데이터베이스를 좀 더 효율적으로 보고자 했던 시기와 맞닿아 있다. 그러나 지금까지 월마트의 데이터 관리에 관한 논의는 대부분 생산관리, 재고관리 등 운영 측면이 강조되어 왔고 데이터 자체에 대한 관심은 상대적으로 적었다고 할 수 있다. 본 연구는 데이터베이스에 관한 기술적인 개념을 먼저 아우른 뒤 월마트의 데이터 웨어하우징 프로젝트 사례를 구축 전(준비)-구축(실행)-구축 후(평가) 단계로 나누어 분석하였다. 본 연구는 월마트가 데이터 웨어하우징을 진행하면서 조직에서 지속적으로 발생하는 문제를 어떻게 해결하였는지, 그리고 데이터 관리를 통해 어떻게 전사적인 공헌을 이룩하였는지에 초점이 맞추어져 있다. 산업을 막론하고 전 세계적으로 가장 큰 데이터베이스를 가지고 있는 월마트의 사례를 현재의 관점에서 다시 살펴봄으로써 최근 재조명되고 있는 (빅)데이터 이슈와도 연결점을 찾을 수 있을 것이라 기대한다.

최근 웹 기술의 확산과 정보기술의 발달로 교육분야에서 컴퓨터의 가치는 더욱 높아지고 있으며, 기존의 교실위주의 수업보다 시간적 공간적 제약을 덜 받게 되는 WBI(Web Based Instruction)는 무한한 발전 가능성을 제시하고 있다. 하지만 기존의 WBI에서는 교수가 수업 평가 후 학생에게 수업의 결과를 알려주는 형식이었고, 또한 학습자에게는 일률적으로 평가가 적용되어 학생의 수준에 맞는 수업을 할 수가 없었으며, 교수의 입장에서도 학생들의 평가 결과가 수업의 질을 높이거나 내용을 변경시킬 적당한 근거 제시의 어려움을 가지고 있었다. 본 논문에서는 수준별 학습을 위한 단계별 예비 테스트와 학습 후 다양한 방법으로 테스트의 평가내용을 시각적으로 제시하고, 또한 교수가 평가의 준거를 입력하고 학습자의 평가결과와 교수의 평가준거를 비교할 수 있는 교수지원 컴포넌트를 설계 구현한다. 이는 체계적인 평가 방법론이 되고 학습의 패러다임을 바꾸거나 과목을 변경할 경우, 그 결과에 따라 교수 방법의 변화나 수업내용을 변경하고자할 때 용이하다. 또한 유사한 다른 패러다임의 WBI 시스템에서도 이미 개발된 컴포넌트를 사용함으로써, 유사 응용 시스템의 개발 시 제시된 컴퍼넌트 사용의 용이성과 이식성, 재사용성을 높일 수 있게 한다.

PURPOSE: To investigate the validity of a smartphone application for post-stroke daily living activity management based on an evaluation by users and experts. METHODS: The study design adhered to the analysis, design, development, implementation, and evaluation ADDIE (Analysis-Design-Development-Implement-Evaluation) model. We downloaded the application onto the smartphones of 33 users and 30 experts, taught them how to use it, and asked them to use the application for four weeks. The users' daily lives before and after using the application were compared based on the K-MBI (Korean Version of Modified Barthel Index) to evaluate the usability of the application. For the expert group, we investigated the content validity and reliability of the application and evaluated the usability of the application. Data were analyzed using the SPSS 21.0 software. Users' general characteristics and experts' evaluation scores were analyzed using descriptive statistics. Content validity was tested using the content validity index (CVI), and reliability was tested with Cronbach's alpha. Users' K-MBI scores before and after using the application were compared with the paired sample t-test. RESULTS: Users gave an average rating of 2.93 out of 4 for the application for managing the daily lives of stroke patients, while experts gave an average score of 3.14. With regard to the K-MBI scores, only the dressing score improved significantly (p<.005) after using the application, and scores for other categories slightly improved but not to significant levels. CONCLUSION: The results of this study suggest that the STROKECARE application is usable and could help stroke patients manage their daily lives.

Background Pain in the postoperative body contouring patient has traditionally been managed with narcotic medication. In an effort to minimize side effects and prevent addiction, plastic surgeons are searching for novel ways to provide adequate analgesia, one of which is nerve blocks. This study was conducted with a meta-analysis that evaluates the efficacy of these blocks for patients who undergo breast surgery. Methods A search of the PubMed/MEDLINE database for articles including the terms "post-operative analgesia" OR "postoperative pain management" AND "in plastic surgery" OR "in cosmetic surgery" OR "in elective surgery" in February 2019 generated five studies on elective breast augmentation and reduction mammoplasty that reported pain scores and quantities of opioids consumed. Independent samples t-tests, one-way analysis of variance, and a random effects model were implemented for evaluation. Results A total of 317 patients were identified as having undergone body contouring of the breast, about half of which received a nerve block. Pain scores on a 1-10 scale and opioid dose-equivalents were calculated. Those who were blocked had an average score of 2.40 compared to 3.64 for those who did not (P<0.001), and required an average of 5.20 less narcotic doses (P<0.001). Pain relief following subpectoral augmentation was best achieved with type-II blocks as opposed to type-I and type-II with serratus plane (P<0.001). Conclusions The opioid epidemic has extended to all surgical specialties. Implementation of a nerve block seems to be an efficacious and cost-effective mechanism to not only help with post-operative pain, but also lower the need for narcotics, especially in subpectoral augmentation.

Prestressed composite steel-concrete beams are still a technology restricted to repair sites of large-scale structures and spans. One of the reasons for that is the absence of standard frameworks and publications regarding their design and implementation. In addition, the primary normative codes do not address this subject directly, which might be related to a scarcity of papers indicating methods of design that would align the two technics, composite beams and external prestressing. In this context, this paper proposes methods to analyze the sizing of prestressed composite beams submitted to pre-tension and post-tension with a straight or polynomial layout cable. This inquiry inspected a hundred and twenty models of prestressed composite beams according to its prestressing technology and the eccentricity and value of the prestressing force. The evaluation also included the ratio between span and height of the steel profile, thickness and typology of the concrete slab, and layout of the prestressing cables. As for the results, it was observed that the eccentricity of the prestressing force doesn't significantly influence the bending resistance. In prestressed composite beams subjected to a sagging moment, the ratio L/d can reach 35 and 30 for steel-concrete composite slabs and solid concrete slabs, respectively. Considering the negative bending moment resistance, the value of the L/d ratio must be less than or equal to 25, regardless of the type of slab. When it comes to the value of the prestressing force, a variation greater than 10% causes a 2.6% increase in the positive bending moment resistance and a 4% decrease in the negative bending moment resistance. The pre-tensioned composite beams showed a superior response to flexural-compression and excessive compression limit states than the post-tensioned ones.

The purpose of this study is to investigate a student's career maturity during a career exploration program based on the ecological system perspective and to propose directions for the career maturation process to help H. Meister High School students to get jobs. A single-case 12-session career exploration program was applied to a first-year student at H. Meister High School in U. City for 90 minutes per session twice a week. To verify the effects of the program, this study conducted a pre-test and post-test of career maturity to analyze changes. In addition, the study qualitatively analyzed changes in the program activity sheets and process evaluation sheets per session. The results of the study are as follows: Firstly, the career exploration program based on the ecological system perspective conducted with the student at H. Meister High School improved the student's career maturity. Secondly, changes were observed in the scores in the sub-factors of career maturity between the pre-test and the post-test. Significant differences in the results of the analysis of the sub-factors of career maturity indicate that the program had a statistically positive impact on the career maturation process of the participant. In conclusion, as a result of the in-depth implementation of the program for 12 sessions, the participant expressed his desires which were clarified. In addition, a positive career maturation process appears to have taken place, owing to the self-directed program that led the participant to initiate plans and explore his career by himself. This study was conducted as a single case based on the ecological system perspective concerning career exploration and the career maturation process, but it will be necessary to expand the study to investigate the effects of group counseling, information exchange considering peer influences, common discussions on goal-setting, and other methods on the career maturation process.
