When setting the RAM objectives, various data such as expert opinions and the historical data of similar types of equipment are used. However, many times subjectivity is involved in the process of merging and utilizing data, and there are many cases where some information is omitted or an ambiguous method is used. Most of the previous work focused only on the process or method of calculating values using well-organized data rather than manipulating raw data. But if the data manipulation process is not objective, it is difficult to guarantee the accuracy of the results even if the calculation logic and method are accurate. This study proposes a systematic data merging process used to set the RAM objectives using the evidence theory. The proposed method can be used to avoid information loss and merge the data objectively. Moreover, contribute to improving the accuracy of setting the RAM objectives in the future.

The goal setting and performance measurement is essential tool for performance management. If appropriate goal setting and performance measurement is not done, problems may arise in the management. Therefore, in order to improve the efficiency of building production that management is essential. In addition, the construction project objectives established at the planning phase give considerable influence on the success of the construction project. Therefore, objective of this paper is to suggest the necessity of performance goal setting phase. This paper analyzes problems of goal setting phase and suggests the way to improve about problems.

Objective: This study aimed to examine the influences of household chaos on self-control of young children and to investigate whether teachers' limit-setting styles had moderating effects. Methods: The participants were 184 children (83 boys and 101 girls), at age 3 -5, their mothers and teachers working at daycare centers located in Seoul and Gyeonggi-do. The data were analyzed by descriptive statistics, Pearson's correlation, and hierarchical regression. Moderating effects were examined using the Mplus8.0 program. Results: The results indicated that household chaos as well as teacher's permissive and logical limit-setting styles had significant effects on self-control of preschoolers. The lower the level of household chaos was, the higher the level of self-control of preschoolers was. The level of self-control was more likely to be high when teachers used logical limit-setting with detailed explanation to children whereas it was lower when they used more permissive limit-setting. In addition, teachers' logical limit-setting moderated the relation between household chaos and self-control of preschoolers. That is, the effects of household chaos on preschoolers' self-control were mitigated when the level of logical limit-setting was high compared to when it was low. Conclusion/Implications: The results suggested that both household chaos and teachers' limit-setting styles play important roles in increasing self-control of preschoolers.

Background: Early rehabilitation after partial meniscectomy is important to recover the balance of the vastus medialis oblique and vastus lateralis and prevent pathological problems in the lower extremities and the whole body. Objective: To compare muscle activations for patients after partial meniscectomy. Design: Dual-group Pretest-Posttest Design from the Quasi-Experimental Research. Methods: Twenty participants after partial meniscectomy were recruited and were randomly divided into a Q-setting sensorimotor training group (QSMTG) and Q-setting exercise group (QSEG). Muscle activity of the vastus medialis oblique and vastus lateralis was measured before and after intervention. Results: In the two groups, the vastus medialis oblique and vastus lateralis activations increased significantly (P<.05). The Q-setting sensorimotor training group showed more increases than the Q-setting exercise group, and there were significant differences between the groups (P<.05). The activation ratio of the vastus medialis oblique and vastus lateralis had increasingly significant differences in the Q-setting sensorimotor training group (P<.05), and there were no significant differences between the groups (P>.05). Conclusion: Q-setting exercise with sensorimotor training was a useful method that improved the balance of vastus medialis oblique (VMO) and vastus lateralis (VL) activity after meniscectomy.

The products to meet the requirement of are installed in nuclear power plant and the reliability target should be provided in the requirement. However, it is not easy to set a reliability target using quantitative analysis. The objective of this paper is to propose a method of reliability target setting considered warranty cost for process controller and then compare a reliability target with reliability analysis result.

Instead of sensory evaluation, we designed an evaluation method of the setting function of hairstyling products, based on an original theory focusing on changes in bending stress observed when a load with continuous bending is applied to human hair. Specifically, we developed a device to measure bending stress to quickly and objectively evaluate the condition of human hair, particularly its dynamic properties such as the setting function, following the application of hairstyling products. This device generates a load with continuous bending while applying a pendulum motion to a hair tress, one end of which is anchored. The setting function and holding power of resins of various molecular weight and ionic properties were evaluated using this device. The results demonstrated a close correlation with those obtained by experts' sensory evaluation. The evaluation results of bending stress and holding rate confirmed that the combined use of two different resins could improve the function of setting preparations. Evaluation using this device was able to substitute for sensory evaluation, and offers quick objective evaluation and detection of changes in the holding power of hairstyling products over time. We conclude that evaluation using this device is a promising new method.

This study was conducted to generate fundamental data required by food coordinators and food space creators for planning and directing table settings. The results of this study were then used to suggest an ideal model of table settings for Korean-style food equipped with simple, sophisticated, and practical characteristics. Specifically, this study evaluated the importance of hygiene (safety, cleanness, arrangement), decoration (dignity, form, stylishness, presentation of food on plates), naturalness (seasonal beauty, comfortableness, natural beauty), and modernity (modern style, chic style, urban style). These factors were evaluated according to the preference of the table setting and the characteristics of the meeting, which fit various meal cultures, times, places, and objectives. The results of this study indicate that people prefer hygiene and decoration for family meetings (bansang setting), hygiene and modernity for friendly meetings (simple buffet setting), hygiene and decoration for company meetings (simple buffet setting), and hygiene and decoration for academic meetings (tea party). Hygiene and decoration were highly evaluated in most cases, which indicates that individuals at meetings for special purposes give weight to the meeting's atmosphere, but also consider the hygiene and cleanliness of the food.

상수도 관망은 대표적인 사회기반시설로 수원으로부터 수용가에 이르기까지 안정적으로 유량을 공급하는 것을 목표로 한다. 상수도 관망의 최적설계는 요구되는 절점의 수압, 관로의 유속 등 수리학적 제약조건을 만족시키는 범위 안에서 비용을 최소화하는 설계안을 얻어내는 것을 목표로 시작하였다. 하지만 비용만을 고려한 과거의 상수도 관망 최적설계는 미래의 불확실한 조건에 매우 취약하고, 사용자의 다양한 요구를 충족시키지 못한다. 이 때문에 현대의 상수도 관망의 설계시 다양한 설계인자의 고려와 함께 효율적인 최적설계기법 적용의 필요성이 대두되고 있다. 따라서 본 연구에서는 상수도 관망 최적설계에 다양한 설계인자를 동시에 고려하기 위해 다목적 최적 설계기법인 Multi-objective Harmony Search 알고리즘을 적용하였다. 또한 다목적 최적설계의 효율성 증대를 위하여 매개변수 자동보정 기법 중 하나인 Parameter-Setting-Free (PSF) 기법(Geem and Sim, 2010)을 사용하였다. PSF 기법은 최적화 알고리즘의 매개변수 설정의 번거로움을 없애고, 반복수행을 통한 해 탐색이 진행됨에 따라 가장 효율적으로 작용하는 매개변수를 자동으로 설정하여 탐색효율을 강화하도록 고안된 기법이다. 본 연구에서는 제안된 기법을 실제 상수도관망의 최적설계에 적용하였고 그 결과를 분석하였다. 그 결과 제안된 기법을 통해 관망의 비용을 포함한 다양한 설계인자를 동시에 만족시키는 최적설계안을 효과적으로 도출 할 수 있었으며, 매개변수 자동보정 기법의 적용을 통해 해 탐색의 효율성과 편의성을 향상시킬 수 있었다.
