Phlorotannins are reported to have diverse biological properties. However, no analytical methods for the standardization of phlorotannin preparations have been reported. Herein, we developed and validated an analytical method for the determination of dieckol in phlorotannin extracts (PRT) using high-performance liquid chromatography (HPLC). The optimum HPLC conditions consisted of a Supelco Discovery C18 column stationary phase, a mobile phase (A: 15 % HPLC grade methanol in deionized water, B: methanol), UV detection at 230 nm, and a flow rate of 0.7 mL/min. The optimized chromatographic conditions were validated and exhibited good specificity and linearity ($R^2$ > 0.9994-1.0000). The recoveries were in the range of 100.9-102.3 %. The method had good intermediate (%RSD 1.2) and intra-day (%RSD 0.4-1.7) assay precisions. This HPLC method had good accuracy and quality in the determination of dieckol in PRT.

The modern logistics has tried not only to convert the conventional packing system into unit load system using pallet but also to enhance the fitness between packing facilities and transport modes. This is based on the goal to reduce total logistics cost using logistics efficiency. Because the packing unit can affect on both loading rate and loading facilities, the basic form of packing unit is very important to the unit load system. In Korea, the standardization of logistics has been centered on pallet, and the basic condition will be continued except of the variety of standardized pallet form. Because of this, to enhance the standardization of pallet, it is necessary to develop new standard size and form of pallet. The object of this study is to develop a new method of collecting the effectiveness of standardized packing module. The new method is based on measure of effectiveness (MOE) which can be developed by expert survey. This study has originality from the fact that the collecting method for effectiveness of pallet standardization has not been developed up to now.

Today, wearable technology products are used in a wide range of consumer, healthcare, bio-medical, and industrial applications. The market for wearable technology products is expected to increase dramatically over the next several years. In addition, concerns for safety, performance and reliability of wearable products keep increasing and will be essential for widespread acceptance in the marketplace. Wearable smart devices, which are generally in contact with the human body and skin, are exposed to the risk of the electric shock, burn, and explosion. Therefore, the standardization of wearable devices in terms of human safety and reliability should be very important. Furthermore, the development of test method and test certification of the wearable products will be one of the key technology for mass production. Such standardization and certification will help consumers to choose the safest and best quality wearable devices and allow manufacturers to prove the safety and quality of their products, thereby helping them to gain a competitive technology. This paper discusses the current status of the wearable smart devices as well as the standardization and test certification applicable to wearable technology products.

With the advent of smart age, the concern on smart work has gradually increased in the situation that creative innovation capability has become one of the important elements in business competitiveness. Most domestic small and medium-sized businesses have partly introduced smart work system due to the lack of its recognition and understanding about a specific method to implement. Under the environment, it is essential to make standardization strategy and do systematic implementation for core technology which leads global market in order to secure the dominant position in smart work related technologies. Therefore, this paper suggests standardization items which lead global standard and implementation direction on standardization through analysing the current situation introducing smart work in small and medium-sized business and technology/standardization trends.

Purpose of this study is to empirically consider relation between QM activity factor and management result. For this, following 6 major variables of QM activity were established as independent variable; CEO's leadership, communication, process control, standardization, full participation and education/training while satisfaction of members and improvement of quality were established as dependent variable. And, a model was set up and hypothesis verification was conducted on the basis of data collected through questionnaires. The results are summarized as follows; First, QM factors which influenced satisfaction of members in management result were CEO's leadership, communication, process control, full participation and education/training but 'standardization' factor was not statistically significant. Second, QM factors which influenced improvement of quality in management result were CEO's leadership, communication, standardization, full participation and education/training but 'process control' factor was not statistically significant. Third, among main factors of QM activity, the factor which preferentially influenced satisfaction of members was 'full participation' factor while the factor which preferentially influenced improvement of quality was 'standardization' factor. According to such results, it is required to seek a statistical method regarding QM activity with focus on the factor of 'full participation' and 'standardization' among other things for the purpose of satisfaction of members as well as improvement of quality. It is believed that implication of this study can be useful information to realize management result considering main factors of QM activity and that it also can be basic reference data to seek a statistical method for satisfaction of members and improvement of quality by grasping core factors having influence over QM activity.

The floor slip test method using O-Y·PSM was developed based on the risk assessment and sense of slip by the users implementing actions such as changing walking direction on a floor. This test method is regulated under the Korea Industrial Standard KS M 3510, and in the Korea Industrial Standard KS F 3230, the article of KS M 3510 is cited. Yet, in the standard, the surface condition of test or slip adjustment method is merely mentioned or difficult to be found, and thus it creates confusion in floor slip test using O-Y·PSM. Therefore, this study is to provide the useful data to revise the relative standard through the standardization study including various surface conditions of sample and slip adjustment method used in floor slip test method using O-Y·PSM.

This study utilized a standardization and cluster analysis technique for the selection and classification of beneficial bacteria. A set of synthetic data consisting of 100 individual variables with three characteristics was created for analysis. The three characteristics assigned to each independent variable were designated to have different numeric scales, averages, and standard deviations. The variables were bacterial isolates at random, and the three characteristics were fermentation products, including cell yield, antioxidant activity of culture, and enzyme production. A standardization method utilizing a standard normal distribution equation to record fermentation yields of each isolate was employed to weight their different numeric scales and deviations. Following transformation, the data set was analyzed by cluster analysis. The Manhattan method for dissimilarity matrix construction along with complete linkage technique, an agglomerative method for hierarchical cluster analysis, was employed using statistical computing program R. A total of 100 isolates were classified into groups A, B, and C. In a comparison of the characteristics of each group, all characteristics in groups A and C were higher than those of group B. Isolates displaying higher cell yield were classified as group A, whereas those isolates showing high antioxidant activity and enzyme production were assigned to group C. The results of the cluster analysis can be useful for the classification of numerous isolates and the preparation of an isolation pool using numerical or statistical tools. The present study suggests that a simple technique can be applied to screen and select beneficial microbes using the freely downloadable statistical computing program R.

In this study, a neural network algorithm through a data standardization method was developed to discriminate the phase-shifted partial discharge(PD) patterns such as a $\phi$-q-n pattern. Considering the PD measurement in the field, it is not so easy to acquire absolute phase angles of PD pulses. As a consequence, one of the significant problems to be solved in applying the neural network algorithm to practical systems is to develop a method that can discriminate phase-shifted $\phi$-q-n patterns. Therefore, authors established a new method which could convert phase-shifted $\phi$-q-n patterns to a standardized $\phi$-q-n pattern which was not influenced by phase shifting. This new standardization method improved the recognition performance of a neural network for the phase-shifted $\phi$-q-n patterns considerably.

The technique of the calculation for probabilistic functions used in the reliability analysis of agricultural structures is proposed in this paper for adapting the standardization method using a numerical intergration. The proposed standardization method deals with the structures whose deviations of material properties and loads are large such that the deviation range from 20% to 70%. The results computed by the proposed method are compared with those obtained by the Monte Carlo Simulation. Deterministic values such as deflection, stress, obtained by conventional structural analysis can be directly changed to probabilistic distributions by the proposed method.

This study explores standardization plans concerning industrialization of Hanjii which is traditional culture resources of rural community. Hanji is very useful in many ways, and its usefulness is not confined to only paper. In other words, it comes to have architectural uses, agricultural uses, clothing uses, and medical uses through fusion and convergence. However, the expansion of Hanji market dose not lead to profits for related stake holders because its standardization is not nurtured yet. For standardization, this paper argues, first, a industrial definition of Hanji is needed in which Hanji's own characteristics is involved. Besides maintaining traditional characteristics, the definition and quality standards of Hanji needs to be established by considering a given condition of Hanji industy. Second, a satisfactory method to measure Hanji's own material characteristics(i.g., mulberry paper content and long-term sustainability), which affects Hanji's quality, needs to be developed and standardized. Third, a government standard is urgently needed in order to keep consumers from being confused when they select Hanji products. The standardization of Hanji products and technology needs to be established in both case of current Hanji market and newly developed products and technology.
