  • The objective of this study was to determine the extent to which acetaldehyde (AA) and formaldehyde (FA) migrated from polyethylene terephthalate (PET) bottles into mineral water during storage at 25 and 35$^{\circ}C$ for 240 days. Generally, AA and FA were observed to migrate more at 35$^{\circ}C$ than at 25$^{\circ}C$. The amount of FA in the samples irradiated under UV lamps was higher than in those stored in the dark over the storage period and vice versa for AA. Using a triangular test, the sensory panels distinguished a difference between one sample and the other two mineral water samples that had been exposed to UV lamps after 60 days of storage at 35$^{\circ}C$ (p<0.05). At this time, FA and AA concentrations were measured at 267.4 and 515.3 g/L, respectively. After 120 days, an independent mineral water sample from the other two samples in all treatments could be distinguished by the panel members at a significance level of p<0.001.

  • This study aims to identify and analyze the main factors that determine the properties and buying behavior in the premium bottled select and analyze the degree of impact on the relevant variables are premium water demand. When applied to the truncated negative binomial model to derive the study results: The results of estimating the variables that affect the demand for premium mineral water are as follows. Premium bottled water demand of this group my purchases with a choice between buying behavior variables are significantly higher than the relative population. To also do a good ingredient water, it appeared to be on a statistically significant positive effect on the demand for the more groups you purchase a premium bottled water for the purpose of receiving special feeling, just buy purpose is called to drinking water does not significantly affect to be analyzed. Among demographic characteristics it showed that demand for premium bottled water purchases are significantly higher in women than in men, professional / clerical job, such as the military, college graduates were more consumer research as significant in comparison to the relative population. Taste and package design factors of premium bottled mineral water among the select attribute factors are having a significant positive impact on the purchasing demand, local conditions and cost factors have been estimated to be insignificant.

  • This paper proposes a web service that provides consumers with necessary information to make rational purchases of bottled water. The web service or dedicated mobile application introduced in this paper offers brand-specific manufacturer information and bottled water brand information produced by manufacturers. In addition, detailed information about the manufacturer such as location, environmental quality grade of the Ministry of Environment, and brand/capacity-specific prices are provided to consumers who use the proposed service in this paper. By utilizing the proposed service in this paper, users can receive guidance on how to make rational purchases of the bottled water they need, enabling them to consume economically and healthily.

  • Drinking water has lots of minerals, especially calcium, sodium, kalium, magnesium, and fluoride must be labelled on the bottle about their contents. Minerals like calcium, magnesium, and fluoride have influence to the tooth development. Appropriately taking some minerals, dental caries can be prevented somewhat degree. There is no guide line about innoxious minerals like calcium and magnesium, however, noxious mineral like fluoride, should be contained less than 2 mgF/L according to the current drinking water standard. Hereupon, it is necessary to recognize the concentration of fluoride in drinking water, so I studied 15 samples of domestic drinking water on sale about the concentration of calcium and magnesium, fluoride. The results obtained were as follows ; 1. 14 drinking waters in 15 samples showed various Ca concentration. The average Ca concentration is 34.68${\pm}$31.84 mg/L, the highest is 128.91${\pm}$1.85 mg/L and the lowest is 2.0${\pm}$0.02 mg/L. 2. 13 drinking waters in 15 samples indicate the Mg concentration. The average concentration is 9.22${\pm}$11.06 mg/L, the highest is 30.43${\pm}$0.75 mg/L and the lowest is 0.0 mg/L. 3. 11 drinking waters in 15 samples indicate the F concentration. The average concentration is 0.25${\pm}$0.33 mg/L, the highest is 1.13${\pm}$0.04 mg/L and the lowest is 0.01${\pm}$0.03 mg/L. All samples are satisfied the current drinking water standard, 2 mg F/L.

  • 상수원이 오염되고 사람들이 수돗물 수질을 불신함에 따라 이에 대한 회피 행동(averting behavior)으로서 생수소비가 급증하고 있다. 본 논문은 모수적(parametric) 모형과 반모수적(semi-parametric) 모형을 운용하여 생수소비 행태를 설명하는 이변량모형(bivariate model)을 분석하고자 한다. 주된 분석목적은 모수적 모형과 관련된 암묵적인 제약이 반모수적 모형을 통해 완화될 수 있음을 보이는 것이다. 모수적 모형에서 가정되는 이변량 정규성(normality)의 가정에 대한 검정결과, 이 가정은 통계적으로 유의하게 기각되었으며 모수적 모형 대반모수적 모형에 대한 정형검정 결과도 모수적 모형을 유의하게 기각하였다. 또한 반모수적 모형이 모수적 모형보다 생수소비행태에 대한 설명력이 더 높았다. 따라서, 반모수적 모형이 모수적 모형에서 요구되는 제약적인 가정을 하지 않으면서도 자료와 보다 잘 부합하는 결과를 가져올 수 있는 것으로 분석되었다.

  • This study was carried out to identify the volatile organic compounds (VOCs) in polyethylene terephthalate (PET) bottles and to determine the extent to which VOCs migrate into mineral water during the bottling process and storage. A greater amount of nonanal and decanal was generated from the PET bottles than from the PET preforms. Benzene, ethylbenzene, nonanal, and vinyl benzoate were identified from the PET bottles when the incubation temperature of the headspace solid-phase microextraction (HS-SPME) sampler was set to 60, 80, and $100^{\circ}C$. As the incubation temperature increased, the concentrations of nonanal, vinyl benzoate, and decanal increased significantly. When the high-density polyethylene (HDPE) PET bottle caps were extracted with dichloromethane, the level of Irgafos 168 was found to be $206{\pm}20.1\mu}g/g$. The concentration of 2,4-di-tert-butylphenol in water was $4.80{\pm}0.2{\mu}g/L$. Therefore, it is necessary to avoid exposing PET and HDPE resins to high temperatures during the manufacturing process and storage of bottled water.
