Purpose: The purpose of this study was to test the effectiveness of a weight reduction program on the body weight, BMI, self-esteem, and self-efficacy of chronic mentally ill persons. Methods: A nonequivalent control group pre-posttest design was employed. Participants were 46 chronic mentally ill persons who agreed to participate in this study, and were assigned to an experimental group (n=23) and a control group (n=23). The weight reduction program was modified by the author, based on the Wellness program (Lilly Pharmaceutical Company, 2003), Lee (2007) and Kim (2013). Data analysis with frequency, χ2-test, Fisher’s exact test, and t-test was performed using SPSS/Win 18.0 version. Results: The results showed a significant decrease in body weight and BMI and an increase in self-esteem in the experimental group compared to the control group. Conclusion: The weight reduction program had a positive effect on body weight, BMI, and self-esteem. Evaluation of drug compliance and vocational rehabilitation is recommended for long term effect of the program and conduct of further studies will be required for use of various resources for self-efficacy for inclusion in drug education in a program for improved health outcome.

For a Product Oil Carrier, longitudinal bulkhead as well as transverse one is corrugated shape in general and intersection part of bulkheads is utilized for a pipe trunk. Since lower and upper stools are to be connected with all of longitudinal and transverse bulkheads, they have a uniform height respectively. The purpose of this study is the development of design system for the minimization of total weight of longitudinal and transverse bulkheads at the initial design stage. In this study, the beam element models for longitudinal and transverse corrugated bulkheads are established and they are applied to the structural analysis. For the practical design, the selection and the position of an additional pipe trunk are considered in this study. In addition the required minimum distance between the bracket installed along the web of corrugation at lower stool and the diaphragm is taken into consideration during optimization process. Evolution strategy (ES) is adopted as an optimization technique.

Objectives: This multicenter retrospective study evaluated early changes in continuous glucose monitoring (CGM) metrics and metabolic parameters during the initial phase of a Korean medicine (KM) based weight loss program combined with a low-carbohydrate diet (LCD). Methods: Thirty-one participants who wore a CGM device for 14-15 days after starting KM treatment and LCD were analyzed. Weekly CGM metrics, daily trends using linear mixed-effects models, and 1-month changes in body composition and metabolic indicators were assessed. Results: Time in range (TIR) increased by 8.46 percentage points, and coefficient of variation decreased from 0.15 to 0.13, both meeting minimally clinically important difference criteria. The percentage of time below range (TBR) <54 mg/dL decreased from 0.44% to 0.03%. Daily trend analyses revealed significant improvements in TIR and time above range (TAR). After one month, body weight decreased by 3.6 kg, BMI by 1.3 kg/m², and systolic, diastolic blood pressure by 5.6, 4.5 mmHg; HbA1c decreased by 0.4%. Conclusion: KM treatment combined with an LCD produced clinically meaningful early improvements in CGM variability and short-term metabolic outcomes, suggesting potential as an integrative metabolic intervention.

Recently The automotive industry is trying to increase the energy efficiency by reducing the weight of the car body and engine components as a way to achieve high energy efficiency. In particular, the reduction of the weight of the vehicle through the weight reduction of the vehicle body has the advantage that the fuel consumption and the output can be improved. But at the same time, there is the disadvantage that the strength becomes weak due to the reduction of the material thickness. Therefore, in order to overcome these disadvantages, materials with high strength according to the unit thickness have been actively developed, and researches for applying them have also been increasing. In this study, we will investigate the application of cold rolled steel sheet, which is a lightweight material, to a horn bracket that secures a installed in an automobile engine room. The horn bracket secures the horn on the car engine and is bolted to the outer wall of the engine. The momentum is acted on the bracket due to the distance between the bolt fastening part and the car horn installed on the bracket end side. Therefore, the body part of the bracket is more likely to be destroyed by the influence of the continuous stress. In this paper, design optimization for weight reduction and strength enhancement was performed to solve this problem, and possibility of applying the rolled steel sheet material as lightweight material by tensile test and fabrication was confirmed.

최근 체형에 대한 인식의 변화로 국내에서는 체중조절이 사회적인 문제로 다루어질 만큼 커다란 관심의 대상이 되고 있으며, 체중조절을 시도하는 사람들도 급속히 증가하고 있다. 이에 저열량식단과 특수영양식품 등을 이용한 다양한 형태의 비만관리프로그램과 영양교육프로그램이 등장하면서 이들 프로그램의 체중감량효과에 대한 연구가 활발하게 진행되어져 오고 있다. (중략)

최근 들어 국내에서는 체중조절이 사회적인 문제로 다루어질 만큼 커다란 관심의 대상이 되고 있으며, 이에 체중조절을 시도하는 사람들도 급속히 증가하고 있어 이와 관련된 상업성 다이어트 업체들도 현저히 늘어나고 있는 실정이다. 한편, 특정 다이어트제품의 효능평가에 관한 연구는 보고되고 있으나 전체적인 상업성 비만관리 프로그램의 진행방법에 대한 내용이나 프로그램의 실제적인 체중감량 정도와 안정성 평가 등에 대한 연구보고는 전무한 실정이다. (중략)
