  • A variety of standardization methods between two near-infrared (NIR) spectrometers were investigated for the prediction of five constituents in trans-alkylation process. Spectra were collected by two different instruments (one is regarded as mater instrument, other on as slave instrument). Three well-known standardization methods of direct standardization (DS), piecewise direct standardization (PDS) and slope/bias correction of response variable were applied to trans-alkylation samples on the slave instrument. We have examined for a set of reliable standardization samples using smaller number of transfer samples in order to increase efficiency of standardization.

  • The production, distribution, and consumption of Korean medicinal herbs have increased every year because of an increase of health considerations. But there are no sufficient standardization procedures in packaging and distribution systems related to these herb products. The standardization of packaging material and dimension could be a good addition for establishing proper quality control methods for Korean medicinal herbs. Medicinal herbs deteriorate under physical, chemical and biological hazards such as oxidation, textural change under high moisture content, color change by light, sanitation problems by insect invasion and contamination. Packaging standardization with proper functional packaging materials is critical to ensure the qualities of medicinal herbs. Also, storage and distribution efficiencies can be improved by achieving packaging dimension standardization. This review summarizes recent research trends related to quality evaluation methods and major quality deterioration factors of Korean medicinal herbs. This paper also offers reviews on some of problems and challenges in current packaging and distribution systems of medicinal herb industries and briefly suggests advanced quality control methods through packaging standardization.

  • Multi water-loop system is the efficient customer centered facilities of water supply by utilizing the multi water resources. Multi water-loop system is divided into various types. The system is classified potable and non-potable type. Mostly, the potable type utilizes surface water and ground water. However, the non-potable type utilize the multi water resources, such as rain water, sea water, reclaimed water, etc. Selective intake is possible when characteristics of region, physiographic condition and purpose of use are considered. For instance, downtown type, new-city type, agriculture type, island type are available. For development and application of these multi water-loop system, standardization is needed. For standardization, several methods are given; design principles, selection and composition method of multi water-loop system structure, BIM/GIS application method, safety inspection method. Consequently, a road map of design standardization method can be established. In this road map, there are three parts for the standardization of multi water-loop system. Three parts are the considerations, base material and ways of standardization. Design standardization become close when this road map followed by someone who plan the multi water-loop system. In this way, loop system's development is more efficient and economic. In hereafter research, each type's characteristic will be analysed and standardization methods can be established.

  • IPCC showed that calculation of climate vulnerability index requires standardization process of various proxy variables for the estimation of climate exposure, sensitivity, and adaptive capacity. In this study, four different methodologies of standardization methods: Z-score, Rescaling, Ranking, and Distance to the reference country, are employed to evaluate climate vulnerability-VRI (Vulnerability-Resilience Indicator) over Korean peninsula, and the error ranges of VRI, arising from employing the different standardization are estimated. All of proxy variables are provided by CCGIS (Climate Change adaptation toolkit based on GIS) which hosts information on both past and current socio-economic data and climate and environmental IPCC SRES (A2, B1, A1B, A1T, A1FI, and A1 scenarios) climate data for the decades of 2000s, 2020s, 2050s, and 2100s. The results showed that Z-score and Rescaling methods showed statistically undistinguishable results with minor differences of spatial distribution, while Ranking and Distance to the reference country methods showed some possibility to lead the different ranking of VRI among South Korean provinces, depending on the local characteristics and reference province. The resultant VRIs calculated from different standardization methods showed Cronbach's alpha of more than 0.84, indicating that all of different methodologies were overall consistent. Similar horizontal distributions were shown with the same trends: VRI increases as province is close to the coastal region and/or it close toward lower latitude, and decreases as it is close to urbanization area. Other characteristics of the four different standardization are discussed in this study.

  • As technology is developed, the quantity of new vocabularies is increasing more rapidly. So many vocabularies of technology have various meanings for each part and are used diversely according to circumstances. Therefore, the necessity of reasonable methods of standardization and purification is increasing and it is necessary to establish a classification system of terminology for the first phase of the standardization. Firstly, based on classification systems of power and IT standard dictionaries, scientific and technological standard, SPARK, power IT fields of IEC and organization units of corporations, we propose a new classification system for the standardization of power IT terminologies. The classification system consists of a hierarchical structure with general classification, application fields and specific technologies while keeping the conventional matrix-type classification system. And interpretation methods of power IT terminologies, which are classified according to the new classification system for the standardization of power IT terminologies, is proposed. The interpretation works of the power IT terminologies confirm that the classification system is systematic and the interpretation process is efficient.

  • When we evaluate prospective students in the interview process, we have to implement a system in which each student can be fairly judged. This process, the standardization of the scores which the interviewers have produced based on a student's performance, is implemented to ensure that each student receives a score that objectively translates one's performance. Although we don't know exactly how effective the standardization is in many different cases, we have researched which standardization methods are most stable and have minimum risks among the four methods such as STD, Range, MAD and IQR. These methods use scales such as standard deviation, range, maximum median and interquartile range.

  • As a means of achieving fashion technology and scientification, this research on the standardization proposals of body type research methods has the following conclusions: 1. As human body displays different characteristics according to races, regions, sexes, and ages, clothing products (unlike other industrial goods) cannot be subject to global standardization. As a result, clothing size standardization can be desirably regionalized, for example, as Asian, European countries, etc. 2. In order to share human-body-concerned information among nations, programs for raw data exchange need to be urgently developed. 3. Top priority is databasing all raw data at home and abroad. 4. So that the findings of body type research can be practically applied to the concerned industry, industry-academy cooperation and information exchange are a must. While researchers have to heighten the precision of their studies, industrial partners ought to focus on the invaluable importance of academic research. 5. The scientific body type analysis, the basis of fashion technology, as well as the development of its application technology and software are ultimately and urgently required.
