Management status of end-of-life vehicles and characteristics of automobile shredder residues in Korea

An end-of-life vehicle (ELV) is dismantled to recover and recycle any re-usable parts, then shipped to the shredding facility for further recovery of iron with any remaining Automobile Shredder Residue (ASR) to be considered as wastes and to be disposed of by either thermal treatment or landfill. Overall ELVs management status in Korea, including recycling resulting from the dismantling processes, was surveyed using some questionnaires given to dismantlers and other available information to provide some feasible means for future treatment. The averaged recycle rate in the dismantling stage showed a value of 44% and the rest of an ELV was then compressed and transported to shredding companies to recover mainly the iron content which averaged 38.7% of the mass of a new vehicle. The non-ferrous metals such as copper, antimony, zinc and aluminum accounted for only 1.5%. The Shredder dusts (SDs) were found to be composed of light and heavy fluffs and soil/dust and amounted to 15.8% based on the mass of a new vehicle. Dumping of fluff and inorganic residues into a landfill site, however, will be restricted when new regulations are implemented to reduce the disposal amount to less than 5% of a new car as done in European countries and Japan. The detailed characteristics of SDs were investigated to provide an idea of how to treat them in order to meet a future expected enforcement.

Current Status and Future Prospects for Resources Recycling in Korea

ABSTRACT In order to prospect current recycling status in Korea, legislative system and policies relating to recycling, wastes generation and recycling rate were reviewed. Approximately 234,100 ton/day of wastes was generated in 2000; 46,400 ton/day of household waste and 187,900 ton/day of industrial waste. During the last ten years, waste management laws such as waste disposal law, recycling law and environment friendly industry law were prepared. In this article, concerning over waste generation and recycling, recycling law, Extended Producer Responsibility System and the problems and technological developments associated with recycling were summarized.

The Extimated Influencies on the Socioeconomic Status in Korea

韓国における資源リサイクリングの現状と課題

In order to prospect current recycling status in Korea, wastes generation and recycling rate were reviewed. Approximately 180,753 ton/day of wastes was generated in 1996 ; 49,925 ton/day of domestic waste and 130,648 ton/day of industrial waste. During the last five years, waste management laws such as waste disposal law, recycling law and environment friendly industry law were prepared. In this article, concerning over waste generation and recycling, recycling law, Korean Resources Recovery & Reutilization Corporation and the problems and technological developments associated with recycling were summarized.

In Search of Identity in Korean Sociology

Let me start with my anguish over the selec tion of books. The editor asked me to write a review that would give readers a fair sense of what is and has been happening in sociology in Korea. He suggested that I look at the fea tured essays on the ten most influential books of the past 25 years in the May 1996 issue. In an effort to identify the most influential books, I first went through recent issues of major Korean journals in the field. I discovered that most references were to Western literature, particularly that written in English. Western literature also dominates the reading list for graduate courses at major universities in Ko rea. A number of the colleagues I consulted found it difficult to identify Korean produced books influential among Korean sociologists. It appears that Western authors have been enjoying far more extensive influence and readership than Koreans in the sociology COIIIs munity of this nation. Sociology was early recognized, in 1946, as a major discipline by the establishment of a distinct department at Seoul National University (SNU), then newly founded as a national center for higher learning in postcolonial Korea. Currently, however, less than a quarter of Korean colleges and universities 34 out of over 140 operate degree granting programs in sociology. Two thirds of these programs started after 1981. The directory of the Korean Sociological Association (KSA), which has grown from 14 founding tnembers in 1957 to a membership of over 600, shows that domestic graduate training has been highly concentrated in a few institutions, with approximately laalf of the faculty members in sociology holding foreign graduate degrees, for the most part, U.S. Ph.D's. Not until the latter half of the past decade did Korean universities begin to produce a substantial number of systematically trained doctorates in sociology. The paucity and short history of institu tionalized programs, however, should not be mistaken for an indication of the discipline's low status in Korea. Owing to the reputation and influence of sociology as a critical and pro gressive discipline, the establishment of soci ology departments was restricted under successive authoritarian regimes. Throughout the late 1980s, sociology majors took active roles in the student moveIllent for democracy and social justice. In the wake of the dramatic expansion of higher education by abrupt government promulgation in 1981, a young generation of sociologists made inroads into academia as junior faculty members at somewhat less

Tasks facing Korea's private security business, and its prospects for the 2000's

This thesis forecasts changes in both the domestic and overseas public security circumstances, and analyzes the status of Korea's private security, discussing Korea's private security tasks and prospects for the 2000's, based on the results of problem analysis. Korea's private security business began in the early 60's, and has independently developed since the Security Services Act was established in 1977. Since the early 80's, the private security business has marked rapid growth, thanks to the introduction of Japanese private security capital and technology; and, since the successful holding of the ‘86 Asian Games and the ‘88 Seoul Olympics, the private security business has enjoyed remarkable growth year after year. However, behind such growth lie many problem areas. The internal problems afflicting private security service companies include; first, the private security service providers concentrate too much on labor‐based security; second, equipment‐based security business is limited; third, private s...

韓国の公衆栄養状況について

As a result of the Korean National Nutrition Survey over 17 years from 1969 to 1986, and considering the data of other nutritional status survey, we reported changes of nutrition and food intake and recent nutritional status in Korea. In the recent situation of nutrition intake in Korea, it seems that the Korean people almost overcome quantitative problems in general but they are now in the stage of qualitative improvement. A pretty big gap, however, still exists in nutritional status among individual communities and groups. This gap cannot be separated from social and cultural characteristics such as income, educational level, age and sex. When we discuss the nutritional problems in the whole community health, it is inevitable to solve the health and nutritional problems in the vulnerable populations, especially in the low income class of rural district and city by public health approach.
