This article is concerned with various aspects of establishing the global standard for occupational safety and health management system (OHSMS). The notion, main features, and brief history of the OHSMS are presented. The OHSAS 18000, its assets and liabilities, are reviewed as a prototype of the global standard. It is also addressed the possibility of combining ISO 9000(quality management system), 14000(environmental management system) and the OHSMS into the integrated management system (IMS) as a whole. The concepts of internal and external customers are presented to explain why the environment, safety and health should be incorporated into the notion of total quality 'Participation of the members' and 'standardization of the 4Ms (Man, Machine, Materials and Method)'are emphasized as the major enablers of the IMS. Finally, the industrial, academic and governmental roles are discussed for developing the IMS and setting it down into the Korean industries.

The reproducibility of measured level is a prior condition for the reliable assessment of the sound insulation performance. To review the reproducibility of impact sound level, 20 floors were selected in highrise apartment house, and then impact sound levels of two kinds of typical floors were measured with 10 times in each receiving point. The impact sound insulation class values were derived with a standard tapping machine and bang machine. Inspection of the result showed that smaller scale of the room caused to lower the reproducibility and that the higher values of standard deviation in lower frequency caused to deteriorate the reliability of assesment. Thus to enhance the reproducibility of the impact sound insulation class, greater allowable deviation of measured level is required in lower frequency than in higher one.

Radioactivation analysis is based upon irradiation of nuclei with elementary particles. In many cases the interaction gives rise to radioactive nuclei, which can be detected and identified by the emitted radiation. If we irradiate under identical conditions an unknown quantity of a certain atomic species and a known quantity of the same species, the following relatio will exist between the induced radioactivities and the irradiated masses: $\frac{Activity standard}{activity unknown}$=$\frac{Mass standard}{Mass unknown}$ From this equation the mass of the unknown can be easily calculated. This relatively siple technique (abstract made from the irradiating facility) allows quantitative determination of about 60 elements with a sensibility that most of the time considerably exceeds the sensibility of conventional analysis techniques. General review articles from Gordon and Meinke should be consulted for further detail.

Pork is known as one of the preferred part of meat worldwide. Especially, the belly, known as 'Samgyeopsal' in South Korea, has been preferred by consumers in South Korea. Pork belly contained various component muscles, intermuscular and subcutaneous fat. The high-fat belly cut (containing 50%-60% fat ratio) has a low preference in South Korea whereas, the standard belly cut (20%-40% fat ratio) of the consumer preference was different. In addition, the evaluation system focused on lean meat production, represented by loin eye area and back fat thickness. In this review, we discussed the pork belly structure, phenotypic correlation with lean meat production ability and meat quality, and genetic potential to confirm to possibility of application to pig breeding. Moreover, the confirmed possibilities considered that could be a base on the evaluation of standard for the pork belly as an economic trait.

Holography is the most promising 3D imaging technology to faithfully record and reproduce light information. In addition, it is widely explored in metrology for applications such as microscopy and tomography because it can accurately measure 3D shapes. However, the data size of a digital hologram is very large, and the data characteristics are notably different from those of conventional 2D images. The Joint Photographic Experts Group (JPEG) is a group of experts from the International Organization for Standardization/International Electrotechnical Commission. This group develops and maintains standards for still image compression. In 2014, the JPEG released a new standard for 3D image compression called JPEG Pleno to represent light fields, point clouds, and holograms. Among them, JPEG Pleno Holography is the first international standard for hologram compression. We review recent advances in JPEG Pleno Holography standardization and discuss future directions of development.

Perchlorate contamination in aquatic system is a growing concern due to the human health and ecological risks associated with perchlorate exposure. In spite of potential risks associated with perchlorate, drinking water standard has not been established worldwide. Recently, US EPA has issued new protective guidance for cleaning up perchlorate contamination with a preliminary clean-up goal of 24.5 ppb. In Korea, the drinking water standard and discharge standard for perchlorate has not been established yet and little information is available to address perchlorate problems. Perchlorate treatment technologies include ion exchange, microbial reactor, carbon adsorption, composting, in situ bioremediation, permeable reactive barrier, phytoremediation, and membrane technology. The process description, capability, and advantage/disadvantages of each technology were described in detail in this review. One of recent trends in perchlorate treatment is the combination of available treatment options such as combined microbial reduction and permeable reactive burier. In this review, we provided a brief perspective on perchlorate treatment technology and to identify an efficient and cost-effective approach to manage perchlorate problem.

The ISO 30301 MSR Standards support successful management of organization while providing strategic plans to the issue of records management. In Korea, these standards are established as the national standard (KS) in May 2013, and also, there are actions being taken to adopt the certification of the ISO 30301 Standards. However, to adopt such certification, it is required that the certification operation system needs to be organized, as well as that the society in general should understand about records management. Accordingly, it is even more required an review on the adoption of the system. This study has the purpose in surveying a variety of stakeholders' perception for the adoption of ISO 30301 certification given the circumstance that the ISO 30301 certification is not yet adopted in Korea. For this purpose, the research is implemented through literature review and in-depth interviews. Firstly, the literature review looks at ISO 30301 standards and the concept of certification that is being carried out with the ISO 30301 Standards, and it discusses the necessity of the adoption of the relevant standards' certification. Secondly, there are in-depth interviews carried out to study for the adoption plan for the ISO 30301 certification. The participants to the interviews include five records and certification related experts and five records managers at public institutions whose records management is supervised by National Archives of Korea. Interview data was analyzed based on grounded theory methodology. This study will be able to provide significant implication to build a successful plan for the adoption of ISO 30301 certification by reviewing perception of professional and problem, strategy of this certification.
