This study suggested practical application of decision aid tool on re-evaluation of current buildings with a focus on a energy and economics evaluation methodology. In Europe, over forty percent of all construction activities are for retrofit. For efficient construction, various tools for re-evaluating existing buildings have been developed and are in use. Legislations of relevant laws and studies are actively initiated. In particular, EPIQR (Energy Performance Indoor environment Quality Retrofit), which was developed through the EU's Third and Fourth Framework Programs laid a foundation on a new concept-based decision aid tool for re-evaluation of existing buildings. As for actual applications, based on this, EPIQR+ was developed to be in line with a building maintenance guideline (SIA 469) and is actively applied to public buildings. This tool quantifies the degree of damages of existing buildings and suggests alternatives to users in energy (SIA 380/1) and economical perspectives. This study examined these preceding tools and suggested some trenchant approaching for more comprehensive and efficient use of re-evaluation tools in building maintenance.

The Purpose of the current study is to investigate the differences in cosmetics attribute evaluation, purchase motivation, and brand re-purchase intention with respect to shopping orientations of Korean female university students. Questionnaires were distributed to 250 female students at Kyungpook National University and 220 completed questionnaires were analyzed. The results were as follows. First, shopping orientations and cosmetics attribute evaluation each generated four factor solutions, whereas cosmetics purchase motivations produced three factors. Second, three consumer groups - Efficiency Shopper Group, Indifference Shopper Group Ambivalence Shopper Group - with different shopping orientations were identified. Third, the study found significant differences in consumers' attribute evaluation such as function and price among the groups. The study also revealed a significant difference in contingent purchase motivations and brand re-purchase intention among the groups. From these results, we could identify that cosmetics re-purchase intention was significantly different among three different groups with different shopping orientations. Furthermore, consumer classification according to shopping orientations in cosmetics product purchase can be used by cosmetics marketers and managers to establish product plan and marketing strategy development. Additionally, the current study has originality and value that the relationship between shopping orientation and re-purchase intention has not been studied very much in the cosmetics product domain.

Recently, the high-rise apartment housings have become a prototype of the urban residential dwelling in Korea and the numbers of one have steadily been increasing. According to this trend, the strength of the construction materials is also fortified to assure the stability and durability of the buildings. Specially, Re-bar of SD500 type is largely used at the construction sites of high-rise building. This study analyzes the current usage of SD500 high-strength re-bar at domestic construction sites. Through the result of this analysis, we develop Economic Evaluation Model that measure economic efficiency of lap splice and coupler splice, which are most commonly used in connection SD500. The evaluation method was applied to construction sites in Seoul in December 2006, and the result revealed that coupler splice is relatively superior in terms of cost efficiency when the re-bar diameter is longer and the concrete strength is lower.

As time passes, the aging of the plant building, the building's energy performance degradation than the initial plan does not express a situation could arise. This year, the certification of buildings certified in 2009 has expired for measures such as the situation required. In this study, management of national and international green building certification and re-certification was compared in two ways. First, the evaluation of green building certification system management assessments were compared. Second, the green building certification system for the re-certification analysis. As a result, G-SEED was not reflected life-cycle of building in management assessment and the commissioning of G-SEED is the UK and the U.S and other concepts of evaluation. In addition, the re-certification system is insufficient about substantial energy consumption of buildings. In this study, the revised the management assessments in conjunction with the re-certification system to manage the building is proposed to improve. In addition, the current evaluation of the existing building certification "existing building" and "building the first certified" as it is more efficient to separate the information into assessment was judged. Green building certification system to meet the purpose of management and operation, and disposal phases of the building to promote energy conservation and sustainability in order to the management a systematic and detailed evaluation and re-certification system developed for the revision of the specific items required and future research want to continue.

Objectives: This study aimed to develop evaluation criteria for the elementary-school-based health promotion program using the RE-AIM framework and to examine their feasibility. Methods: Previous evaluation studies on health interventions for elementary-school students using the RE-AIM framework were reviewed systematically to identify appropriate evaluation criteria. A diet and physical activity intervention based on the transtheoretical model was implemented in a pilot study using the "Happy Me" application. The feasibility of using the RE-AIM framework to evaluate it was examined. Results: The review yielded the following evaluation criteria: "reach," the ratio of participants out of the total target population; "efficacy/effectiveness," the difference in outcomes between the intervention and control groups, or between a pre- and post-test; "adoption," the rate of use of the program and participation in the next stage of the program; "implementation," the progress on the program components; "maintenance," the participants' and teachers' intention to continue using the program. The pilot study reached 76.6% of the targeted population. The intake of sugar-sweetened beverages decreased (P < 0.0001), and the duration of walking increased (P < 0.0001). Other indicators could not be evaluated; therefore, potential indicators were suggested. Conclusions: This study produced feasible evaluation criteria for elementary-school-based health promotion using the RE-AIM framework. Nevertheless, the feasibility needs to be validated with a broader range of studies and long-term interventions.

The synthetic breaking test method was developed to evaluate the breaking performance of ultra high-voltage circuit breaker and made up of two independent circuits; current source circuit and voltage source circuit. In application of this test method, it is necessary to extend the arc of the test breaker. So, the new re-ignition system using VTGS (Vacuum Triggered Gap-Switch) was constructed to improve the efficiency and reliability of this test. In this re-ignition system, VTGS operates in high vacuum state of $5{\time}10^{17}$torr and control system consists of the triggering device and the air M-G (Motor-Generator). This re-ignition system showed the operating characteristics, such as delay time ($t_d$) and jitter time ($t_j$ not exceeding 5us and 1us respectively, and had the operating voltage of $25\~150kVdc$ at the gap distance of 24mm.

Objective: This study describes the case of a patient with a left basal ganglia (BG) infarct who had made almost a complete recovery upon discharge from the hospital in 2014 but who was re-admitted after 31 months with a worsened hemiplegic gait. Methods: The patient had undergone no rehabilitation treatment in the 31 months since his discharge. When the patient was re-admitted to our hospital in 2017, stance and gait data were collected on the patient using a treadmill gait analysis system. In addition, the patient underwent a manual muscle test (MMT) evaluation, and his Motricity index (MI) and modified Barthel index (MBI) scores were recorded. After rehabilitation for one month, the patient was reassessed, and the results were compared to those on the day of re-admission and those recorded in 2014. Results: Compared to the 2014 evaluation results, the patient's stance parameters and gait parameters had worsened at re-admission. However, there was no significant change in the patient's MMT grade or MI and MBI scores in comparison to the results of the 2014 evaluation. After one month of rehabilitation, the patient was re-evaluated again, but there was no significant change in comparison to the evaluation results at re-admission. Conclusion: Some of the stroke patients who have passed six months since the onset of their stroke may require ongoing rehabilitation although the functions of them is almost recovered. Because there is a possibility that recovered functions get worse again without any rehabilitation for a long time. And once the recovered functions get worse, re-recovery of them is not easy.

In this paper, we present a design for a retraction-type actuator (ReACT) that has the characteristics of both thermomechanical metamaterials and displacement amplification mechanisms. The ReACT consists of an actuating bar, a diamond-shaped displacement amplification (DA) structure, and a slot for loading thin-film heaters formed through the actuating bar. When power is supplied to the thin film heater, the actuating bars contacting the heater thermally expand, and the diamond-shaped DA structures retract in the longitudinal direction. The performance characteristics of the ReACT, such as temperature distribution and retracting displacement, were calculated with thermomechanical analysis methods using the finite element method (FEM). Subsequently, the ReACTs were fabricated using a polymer-based 3D printer that can easily execute complex structures, and the performance of the ReACT was evaluated through repeated tests under various temperature conditions. The results of the performance evaluation were compared with the results of the FEM analysis.

This study introduced food waste into re-vegetation base materials for surface loss recovery of carry-away highway cut slope. The object of this study is to derive the mixing ratio of food waste by conducting a test installation, monitoring, analysis and evaluation for recovery of carry-away highway cut slope. The following items were investigated and analyzed each experimental zone to draw mixing ratio of re-vegetation base materials and food waste : the physical and chemical properties of the vegetation base materials, soil-hardness, soil-humidity, left out and the collapsed point, established number of trees, species richness of grass species and tree species, coverage, pest status, and invasion of disturbance species. The re-vegetation method was evaluated by each experiment zone which has different mixing ratio. As a result, experiment zone A was rated 45 points out of 60 rating points as the best re-vegetation method. However, this study result has been derived from one construction and short-term monitoring. In order to derive the suitable and dependable mixing ratio, conducting an objective re-vegetation method evaluation and long-term experiment and monitoring is required.
