The prevalence of obesity is increasing worldwide and has become a serious epidemic health problem. We developed the 'Change 10 Habits' educational program based on obesity treatment and dietary guidelines and examined its effects on customized nutrition education in mildly obese adults. The study was approved by the Institutional Review Board. Study subjects were excluded if they had several major diseases, if had consumed an anti-obesity drug, or if they practiced an obesity-related program within 30 days. The subjects (n=87, $25{\leq}BMI$ <30) were each exposed to the customized nutrition education program with four lessons according to the stage of the transtheoretical model (TTM). The stage-matched program was administered for 12 weeks and was run by a clinical dietitian. Overall, subjects who were in the precontemplation/contemplation stage at baseline made progress in the preparation and action/maintenance stage after 12 weeks (P<0.05). For 'Alcohol is consumed, up to 2 drinks per day', the proportion of subjects who belonged in the action/maintenance stage increased from 34.5% to 49.4% at 12 weeks. In addition, scores of all items significantly increased after the program (P<0.05). 'Chew more than 10 times and eat slowly' score significantly increased from $3.9{\pm}2.4$ to $5.8{\pm}2.3$ (P<0.05). In conclusion, behavioral stage-matched nutrition education using the 'Change 10 Habits' program was effective in improving eating behaviors and enhancing healthy lifestyles in mildly obese adults.

The Eco-performance assessment program was developed as part of Eco-performance management for buildings at the national level in developed countries. Cases of domestic Green Building Certification(GBC) system was developed but these program's destination of Eco-performance management for buildings needs systematic management by the limited GBC. Generally in the construction industry, Eco-performance management of Building Life-cycle is required. Therefore this paper develop the creation of Eco-performance information and management process, those are from design and maintenance management phases, through suggest the development of a information management for Eco-performance management of buildings. In addition, it makes to decrease the reproduction of information unnecessarily by analyzation of the related association between the information of facilities objects and Eco-performance management. Finally, study the previous reaserch and suggest the BIM by the method of information management and this paper purpose the development of web-based Eco BIM object library management system.

Since the Fukushima accident in 2011, the importance of the electrical systems in nuclear power plants (NPPs) has been emphasized. The result has been that NPP regulators are enhancing their monitoring of loss of offsite power (LOOP) events. Korea Hydro & Nuclear Power Co. (KHNP) is reviewing the status and issues related to LOOPs, and is attempting to establish specific countermeasures to prevent LOOPs, because they can have severe consequences in the complicated maintenance schedule during an outage. A starting point for preventing LOOPs is the control of the loss of voltage (LOV)-initiating components. In order to reflect this in the risk assessment program, an LOV monitor is being developed for use during plant outages.

In these days, High-strength steel prevails throughout the construction fields for the benefit of structural and economical aspects. But high-strength steel is used by the simple calculation of flexural capacities for the purpose of reducing flexural reinforcement. So, this paper is mainly focused on the shear behavior of high-strength steel reinforced concrete beams without stirrups comparing with normal-strength steel reinforced concrete beams. Specimens were made and tested with the experimental parameters, such as steel yield strength, reinforcement ratios and minimum shear reinforcement. The main result was that not only area but also the yield strength of flexural reinforcement should be considered to predict the shear capacities of concrete beams. In addition, the experimental results were simulated by modified compression field theory analysis program, RESPONSE 2000. A good agreement was achieved between the test results and program analyses.

Recently, regulatory bodies quite often encourage to adopt risk-based inspection (RBI) and management programs because they can enhance safety simultaneously with deregulation in Korea. RBI is an integrated methodology that factors risk into inspection and maintenance decision making. This paper describes an example of how to use known risk assessment codes (API 580, API 581 BRD) to address such safety analysis requirements for risk management in the refining industry. Specifically, this paper reports the methodology and the results of implementation to the Crude Distillation Unit(CDU) plant of refinery units using the $KGS-RBI^{TM}$ program, developed by the Korea Gas Safety Corporation in reference of API Codes and ASME PC (Post Construction) with a suitable consideration of Korean situation. The results of the risk and reliability assessment using $KGS-RBI^{TM}$ program are useful in determining whether the detected defects are tolerable or required to be repaired. The subsequent decisions are to manage the future inspection, repair and maintenance planning in the risk reduction control.
