Background: There is growing international recognition of the need for improvements to national chemical management systems for hazardous chemicals. The European Union has recently introduced the concept of 'essential uses' as a new approach to the management hazardous chemicals by limiting their uses. Objectives: This paper examines the concept of essential uses in chemical management and how to apply it through a case study of essential use. This approach is distinct from the current chemical management system, but seeks to improve its potential benefits by effectively restricting or gradually decreasing the use of hazardous substances. Methods: The concept of essential uses was introduced by reviewing the Montreal Protocol on Substances that Deplete the Ozone Layer, Cousins's three essentiality categories applied to PFAS, restriction options assessed in the PFAS restriction proposal under REACH, and the California Safer Consumer Products regulations prioritizing 6PPD in motor vehicle tires. Based on these essential uses concepts for PFAS and 6PPD, uses of benzene were classified in accordance with the essential uses approach for products using benzene in South Korea. Results: The essential use concept is able to manage the restriction and authorization of substances of concern through essential uses and non-essential uses and the feasible substitution of uses and substances. Conclusions: If the concept and methodology of essential uses are clearly established, they can be expected to shift the national chemical management paradigm from regulating substances to limiting uses under the existing substance management system.

The experiment attempts to find out the effect of the mixture of the antimicrobial agent and insecticide on metallic material including Silver(99.9%), Copper(99.9%), Lead(99.9%) and Iron(99.5%) by Oddy test. The mixtures of the antimicrobial agent and insecticide were prepared in 60ml; with the standard concentration of 17.5% in B77 Essential oil mixture, one for mixture of concentration of ${\pm}1{\sim}2%$ and insect repellent material; the other for mixture of low concentration and antimicrobial agent(BS-2 and BS-3) material. After Oddy test, we investigated the variation in the surface of the samples by visual inspection, weighing, color measurement and SEM-EDS analysis. The result showed that Lead had the biggest change in the surface, and Copper had the biggest change in the color. In addition, changes in the samples before and after the experiment were found to be greatest at concentration of 19% of Essential oil mixture of the antimicrobial agent and insecticide. Also, B78 Essential oil mixture produce change in samples. It means when the concentration of oil mixture rises, the variation of the samples gets bigger. And, the low concentration of mixture including B77 Essential oil mixture and B78 Essential oil mixture also produce big change in the samples. However, the low concentration of B77 Essential oil mixture that do not contain B78 Essential oil mixture was able to confirm that the change of the surface is not large.

The summary of a study of efficacy of Rose essential oil and Lavender essential oil against physiologic active change s of skin caused to surfactant is as follows. 1. In feed intake efficiency, there is more significant difference than control group, and then in water intake, there are significant differences between each group. It is presented that the water intake efficiency ratio of the group treated by Rose essential oil and Lavender essential oil is higher than all of groups to be participated in experiment. And then, the reason that the group treated Lavender essential oil is lower than any other group is needed water intake to be caused by stress. 2. As the result of serum analysis, in atherosclerotic index(A.I), the cholesterol of control group is higher than that of the group treated. As HDL cholesterol is activated, the dan1aged group is higher than control group, in LDL cholesterol the control group is higher. It is seen that the damaged group of the quantity of HDL cholesterol is lower frequently in A.I. This fact is presented that HDL cholesterol that cholesterol is exhausted is changed, because of the dan1aged group that replacement is activated. 3. As the observed result of alteration of sebaceous glands, it is appeared that the demage of sebaceous glands is destroyed in the damaged group. It is observed that epidermis of the group applied by Rose essential oil after treated surfactant is dry, secretion of phenomenon of water and sebum is appeared more. It is observed that the epidermis recovery of the group applied by Lavender essential oil after treated surfactant is insufficient. And then it is seen that stratum corneum is recovered and the quantity of sebum secretion is decreased. 4. As the observed result of alteration of Mast cell group treated by Rose essential oil and Lavender essential oil for 3 weeks Luna's stain(${\times}100$), it is observed that the damaged group treated by Lavender essential oil is numerous in alteration of mast cell's number and Mast cell's size is larger than the dan1aged group. It is presented that the Mast cell's number and Mast cell's size is larger than the damaged group, the Mast cell's size and quantity of the group treated by Rose essential oil and Lavender essential oil is decreased more.

Essential and non-essential amino acids supplemented to culture medium stimulate mammalian embryo development in vitro. Amino acids such as glycine, taurine and alanine are concentrated in the lumen of oviduct and uterus and it can he thought that these amino acids may have physiological role on fertilization and embryo development. Our aim of this experiment was to investigate the effects of essential and non-essential amino acids, taurine or glycine supplemented to fertilization medium on the cleavage and subsequent in vitro development of bovine oocytes matured and fertilized in vitro. Immature oocytes were obtained from slaughtered Holstein cows and heifers and matured in TCM199 containing 10% fetal calf serum, 2.5 $\mu$g /mL of FSH and LH and 1 $\mu$g / mL of estradiol with granulosa cells in vitro. After maturation, oocytes were coincubated with sperm in fertilization medium supplemented with Minimum Essential Medium (MEM) essential and non-essential amino acids, taurine (3.75 mM) or glycine (10 mM) for 30 hours in vitro. Inseminated oocytes were cultured in synthetic oviduct fluid medium (SOEM) containing MEM essential, non-essential amino acids and 1 mM glutarnine up to 8 days after fertilization.Supplementation of fertilization medium with MEM essential and non-essential amino acids lowered significantly (p<0.05 and p<0.001) the cleavage rate after 30 hours of IVF (53.3%) and at Day 3 (62.7%: Day 0: the day of I VF) compared to control (64.3% and 77.3%, respectively). Subsequent developmental rates to morulae (Mo) and expanding blastocysts (ExBL) also significantly decreased (p<0.001 and p<0.05 for Mo and ExBL) when oocytes were coincubated with sperm in the medium containing MEM amino acids. Taurine added to fertilization medium have not increased the cleavage rate over the control, whereas glycine showed significantly lower (p<0.01) cleavage rate at Day 3 than that of taurine, but there was no significant difference in the developmental rates to Mo and ExBL of bovine embryos irrespective of the supplementation of taurine or glycine to fertilization medium. In conclusion, supplementation of fertilization medium with essential and non-essential amino acids, taurine or glycine has no beneficial effect on in vitro cleavage and development of bovine oocytes matured and fertilization in vitro.

Purpose - The development of technologies lead the volume of sale on online market increase but an off-line shopping center is still a core component in the omni-channel strategy. It is generally thought that high-level retailtainment on brick and mortar store affects purchase intentions positively, but some previous studies dispute that and have reported that retailtainment does not affect purchase intentions. So we have studied the additional factors' effect - the nature of purchase and utility - with retailtainment. Research design, data, and methodology - There are 8 treatment groups which were assigned by the method of retailtainment (high vs. low), nature of purchase (essential vs. non-essential), and utility (acquisition vs. transaction). A total of 240 subjects (office workers = 163, 68%; undergraduates = 77, 32%; average age = 30s; female = 39%) were divided into groups and exposed to one of the eight scenarios. Participant's purchase intention was the dependent, and ANOVA and L-matrix were used to analyze for main and interactive effects between factors. Results - First, the main effect and interactive effect between retailtainment and the nature of purchase are significant. We also found that the contrast between essential and non-essential at low-level retailtainment is higher than that of high-level retailtainment. Second, in the case of retailtainment and utility, transaction utility under high-level retailtainment affects purchase intentions positively. Third, between the nature of the purchase and utility, the main effect of the nature of purchase and the interactive effect is significant, but the main effect of utility is not significant. In the case of non-essential goods, the purchase intention was high when transaction utility was provided but in the case of essential goods, acquisition utility increased purchase intentions. Finally, when transaction utility is given, purchase intentions of essential goods increase under low retailtainment, and the purchase intentions of non-essential goods increase under high retailtainment. Conclusions - When customers buy essential goods, discounts decrease purchase intentions. During the season for bargain sales, purchase intentions increase when retailtainment of essential goods is low, and retailtainment of non-essential goods is high.
