Recently, the using of prefabricated temporary equipments is increasing in the industrial field because it can reduce the installation and dismantling period. The various types of prefabricated temporary equipments are manufacturing with various materials in domestic and overseas countries. However, those equipments should win the safety certificate according to the "Governmental Notification about Safety Certification" which regulate the member-based safety certification. It tends to cause over performance of temporary equipments because it couldn't consider structural benefit of the prefabricated products. As the result of this study, it is concluded that the establishment of new safety certification standard for the prefabricated temporary equipments is resonable and the movable scaffold is appropriate for those prefabricated temporary equipment. The movable scaffolds are using as single structure and cannot be expands horizontally. Other types of temporary equipments are using as complex structure which can freely expand horizontally according to the main structure. From the results of the study, the standard of vertical compression performance of prefabricated movable scaffolds should be more than double the performance of single main frame. Other test items of safety certification standard should be fixed when the Notification is amended. The prefabricated temporary equipments which are adopted for the safety standard on assembled structure should be used, moved and kept in assembled state and not separated discretionally. The establishment of new standard for the assembled structure based on this study leads to the development of various types of temporary equipments using structural efficiency of prefabricated structure.

To improve environmental problem as globally climate changes, domestic and foreign government have been trying to reduce green gas emitted by all industries. With making the green building certification system that assess the substantiality and energy performance of building, a governments have been using by a way for reducing green gas emitted in building industry. G-SEED(Green Standard for Energy & Environmental Design) developed in Korea have been reinforcing, and a number of projects certifying the G-SEED have been increasing continuously. As a demand of G-SEED certification is rising, a question on the additional cost data as certifying G-SEED is rising. It is because additional cost as getting the certification is important fact for G-SEED level decision and whether getting the certification or not. Therefore, this study analyzed additional construction cost as certifying G-SEED through performance improvement and design change of general office building not to get G-SEED. In conclusion, an additional construction cost ratio of G-SEED projects to the reference building is drawn as certified level; +0.26%, silver level; +2.29%, gold level; +3.89%, and platinum level; +5.48%.

The physical performance of high-strength concrete deteriorates when exposed to high temperatures such as fire. In particular, in the case of ultra-high-strength concrete, there is a high possibility of explosion due to internal water pressure and thermal expansion due to the tight internal structure. In this paper, a fire resistance certification test was conducted for field application of ultra-high-strength fire-resistant concrete, and the fire resistance performance (temperature rise of main rebar) was compared according to the structural concrete cover thickness. As a result, when the covering thickness was 40 mm, three structures did not meet the certification standards, and when the covering thickness was 50 mm, all structures met the fire resistance certification standards.

Government bodies offer various policies and programs to support small and medium sized enterprise. There's no only one business firm's performance model for the management performance assessment for the government's supporting and/or resupporting program. However assessment factor had been supposed to manage for the enterprise. Current assessment standards, that is Business Innovation Small and Medium sized firm Certification Model, Technology Innovation Small and Medium sized firm Certification Model, Productivity Management System Certification Model, Small and Medium Sized Firms of Korea Federation of Banks, and Business Performance of the State Owned Enterprise would be collected and then develop performance assessment model for the start-ups small and medium sized firms.

Burglary (also called breaking and entering and sometimes housebreaking) is a crime, the essence of which is illegal entry into a building for the purposes of committing an offence. It is one of the most common types of crime and also a serious issue for every society. A house that is left insecure is an accessible and attractive target for burglars and therefore burglary resistance test & certification system for doors and windows has been developed in many countries. This paper explores several advanced foreign burglary resistance test/certifcation cases (the British SBD, the Dutch KOMO SKH/SKG, the Japanese CP mark, the Australian Standard Certification) for security products and domestic test/certification systems for fire safety products as a comparative study so that any improvement points can be gained for South Korea in the field of security product performance. The comparative analysis results show that South Korea is far behind the security product certification system and needs a lot of improvement in the system by benchmarking foreign cases. The domestic test/certification systems for fire safety products also give some insights for burglary-related security products' performance certification system in Korea. Overall, the need for relevant rules and regulations, the establishment of standards regarding testing and certification, including certified security +hardware product in building security certification system, performance testing as well as production testing (i.e. quality management system evaluation), the basic competency of testers, incentive system for certified/high quality security products were suggested in order to make an optimal model for the security production performance testing and certification system in Korea.

In this study, we organized the test results obtained from the performance tests for the CA certificated air cleaners which had been commercially available in Korea since 2003, and analyzed the correlation among the test parameters such as flow rate, particle collection efficiency, clean air delivery rate (CADR), ozone emission, odor removal efficiency and noise level etc. The noise level of 267 air cleaners were increased as concentrated at the 45, 50, 55 dB, which are the required noise level for CA certification according to flow rate, and ozone emissions from the CA air cleaners were significantly lower than the requirement limit, 50 ppb for 24 hour operation. The average particle collection efficiency and odor removal efficiency were 89.3 and 80.8%, approximately 20% higher than the requirement of CA certification, regardless of flow rates. The particle removal performance of an air cleaner was clearly discriminated by its CADR, and the CADR was obtained with a simple calculation: 0.79 x flow rate. The low differentiation of gas removal performance of air cleaners by the current CA gas test method was improved by 3.2, 751.3, 13.4 times for ammonia, acetic acid, respectively, by adopting the CADR concept and the real time measurement method, FTIR, for gas removal performance test.
