  • To address global climate change, various governments are investing in electric vehicle research and, especially in Korea, the application of electric vehicles to public transportation. The lithium batteries used in electric vehicles typically have an expected life cycle of 2-5 years. If electric vehicles become commonly used, they will generate many discarded batteries that could be harmful to the environment. Additionally, lithium batteries are potentially explosive and should be handled appropriately. Thus, reverse logistics issues are involved in handling expired batteries efficiently and safely. Reverse logistics includes the collection, recycling, remanufacturing, and discarding of waste. This study developed a reverse logistics process for electric vehicle batteries after analyzing the as-is process for lead and lithium batteries. It also developed possible disposal regulations for electric vehicle batteries based on current laws regarding conventional batteries.

  • Background: Opisthorchis viverrini (OV) infection is the main risk factor for cholangiocarcinoma and is often found in Northeastern Thailand. The prevalence of OV infection and the incidence of cholangiocarcinoma are major public health problems in this region. Objectives: The objectives of this study were to identify factors associated with OV infection among people in Nong Khai Province in order to develop a prevention programme in the community. Materials and Methods: The data were collected in July 2013. Stool specimens were examined for intestinal parasites within hours after collection using a normal saline wet preparation and the modified Kato-Katz technique. A case-control study was conducted to collect information about demographic data, the habit of eating unsafely prepared fish, the safe disposal of waste food, and the practice of defaecating in fields. Structured questionnaires were used to interview 351 participants (117 cases and 234 controls) in a random selection of 30 villages across Nong Khai Province. Multiple logistic regression was used to identify risk factors for OV infection. Results: In the multivariate analysis, the results showed that the factors which had a statistically significant association with OV infection were the habit of consuming unsafely prepared fish ($OR_{adj}=5.17$, 95%CI=2.49-10.74), the similar habit of family members ($OR_{adj}=3.25$, 95%CI=1.63-6.49), a history of O. viverrini infection ($OR_{adj}=5.64$, 95%CI=2.10-15.18), a history of taking praziquantel ($OR_{adj}=5.66$, 95%CI=3.11-10.29), and the unsafe disposal of waste food ($OR_{adj}=2.1$, 95%CI=1.10-3.80). Conclusions: The findings of this study highlight the features on which a community programme should focus in order to reduce the prevalence of opisthorchiasis and incidence of bile duct cancer.

  • In order to control and manage oil-tanker scrapped materials and wastes properly, the actual conditions and global trends of the treatment and the management of ship scrapped wastes were surveyed and some amendments to marine pollution prevention law of Korea were proposed. Global annual volume of scrapped ships was estimated to be about 22 million DWT and most of them were scrapped in 4 major ship scrap countries such as Bangladesh, China. India and Pakistan and in minor ship scrap countries such as Turkey, the Philippines, Indonesia and Vietnam. The industry of ship scrap has been mainly developed in developing countries or undeveloped countries rather than in advanced countries. Most of scrapped ships were found to be small or medium size below 1,000 GRT In Jellanam-Do and Jeju-Do of Korea. Most of ship scrap enterprise and all enterprises of collection, transfer, treatment and disposal for ship scrapped materials and wastes were shown to be small sized in Korea. The regulations and/or rules which shall prohibit or limit trans-boundary movement of overage oil-tankers for scrap from Korea to developing or undeveloped countries, and vice versa should be Included in marine pollution prevention law of Korea. the criteria of manpower and facilities for enterprise of ship scrap, and for enterprises of collection, transfer, treatment and disposal of ship scrapped materials and wastes should be stipulated in marine pollution prevention law of Korea. It is desirable to introduce the system or concept of recycle or reuse of ship scrapped materials and wastes on producer's responsibility into marine pollution prevention law of Korea.

  • This study carried out first a component survey on the domestic waste shipped into a waste disposal facility in B city, and then heavy metal analysis of each component according to the SRF standards. Based on this, this study explored the problems with domestic waste and measures to improve them. The results are as follows. The result of the survey of physical components show that paper accounted for the largest proportion with 20.5 %~59.9 %, metals (including batteries) among incombustibles accounted for 0.0~8.3 %, other inorganic substances, glass and ceramics accounted for 0.0~43.7 % and 0.0 %~19.6 % respectively. However, the proportion of coated viny and plastics, which have high lead and cadmium content, was rather high with 2.9 %~30.9 %. This suggests the possibility that actual concentration of lead and cadmium within SRF is likely to be higher. Among the 15 components contained in the waste brought into the waste disposal facility, 10 components (food waste, textiles, vinyl, plastics, wood, rubber and leather, paper, metals, electronic substrates, and nail polish) were analyzed according to assay samples (approximately 0.1 g and 0.3 g). The result of analysis shows that the amount of Cd and Pb detected in coated vinyl for 0.109 g of assay sample was 98.6 mg/kg and 20.6 mg/kg respectively; 117.0 mg/kg and 29.0 mg/kg respectively for 0.313 g of assay sample. This is high contents exceeding the Cd standard. As for wooden component, the amount of Pb was 480.0 mg/kg for 0.3 g of assay sample. This suggests that there always exists the possibility of exceeding the exposure level of heavy metals (Cd and Pb) in SRF as long as coated wood and vinyl plastics with high contents of Pb and Cd are shipped into the waste disposal facility; and the local government and the residents need to work hard to improve the situation including development of the machine to sort electronic substrates and batteries for separate collection of the waste of coated vinyl and plastics within domestic waste.

  • This paper focuses on the document "Property Ledger of Dr. Rhee," which was a supplement to the Disposal of the Late Dr. Rhee's Property written by the secretarial office of the Cheongwadae (the Korean presidential residence) in 1970. The document contains a list of 311 items, including furnishings and artworks, once owned by President Syngman Rhee. The items had been in the collection of the Cheongwadae, but in February 1970 they were transferred to the family of the late President Rhee. The background for creating this list is as follows. After the April 19 Student Revolution in 1960, a survey was conducted of Rhee's movable assets, including artworks in his private residence Ihwajang. Their transfer to the National Museum was discussed at one point, but it was decided to use them at the Cheongwadae instead. In 1963, however, the transfer of these assets to the National Museum was ordered, and some duplications of the private possessions were sent to Ihwajang House. In 1970, furnishings and artworks stored at the Cheongwadae were also returned to Ihwajang House, and the "Property Ledger of Dr. Rhee" document was produced. This ledger lists works by artists from the Joseon period through the 1960s. It is difficult to identify each of these artworks since no photos are attached and the details provided are minimal. Nevertheless, this ledger is valuable in that the scale of artworks in the collection of the Gyeongmudae (the former name for the Cheongwadae) and Ihwajang House can be partially identified and in that it helps us understand how the issues surrounding the reversion of ownership of these artworks were resolved.

  • This study analyzed policies and guides related to the acquisition of private records at state/provincial archives in the U.S., Canada, and Australia. The purpose of this study is to examine the current status of collecting private records in the governmental archives. The analysis was made based on policies and guides from 14 state/provincial archives, including five in the US, seven in Canada, and two in Australia. From the analysis, the study examined collection areas, types of private records, and colleting methods, such as donation or deposit. It also studied the considerations on transferring copyright, placing access restrictions, and disposing of records. The study made the following suggestions for collecting private records at public archives in Korea: (1) define the collecting areas of private records relevant to the characteristics of a region; (2) determine the acquisition methods, including donation or deposit, and establish a procedure to make an agreement for the transfer of ownership, including copyright, access restriction, and disposal of records; (3) develop cooperation among the related institutions within a region.
