  • 산업의 발달정도, 업종, 규모 등에 따라 수역으로 배출되는 특정수질유해물질은 해마다 그 수, 양, 독성이 증가하여 인간과 생태계에 미치는 영향이 매우 커서 이를 예측하고 관리해야하는 필요성이 점차 증대되고 있다. 이에 특정수질유해물질과 관련된 산업폐수관리법 및 수질기준법의 국가별 현황을 조사하여보고, 궁극적인 수 환경보전목표와의 연관성을 검토해봄으로써, 국내 특정수질유해물질관리의 문제점을 확인한 후에 배출시설관리체계 개선을 위한 국내 배출허용기준을 제안해 보고자 한다.

  • 산업의 발달로 인하여 유해폐기물의 양과 종류가 날로 증가하고 있다. 유해폐기물은 고온에서 분해가 어렵고 연소시 인체에 유해한 성분을 생성하는 Chlorinated Hydrocarbons(Gupta,A.K. and Valeiras,H.A,1984)과 Acetonitrile, 연소성을 저해하는 $SF_6$ 등이 있다. 지금까지 유해폐기물은 처리가격의 저렴성과 기술적 어려움이 적은 매립 및 밀봉등의 방법에 의존해 왔으나, 최근 들어 소각에 의한 처리가 증가추세에 있다. (중략)

  • 유해한 이동코드는 웹 환경에서 흔히 발견될 수 있으며 시스템에서 적재되어 시스템 자원을 독점한다거나 부적절한 방법을 자원을 탐직하는 등의 불법적인 활동을 한다. 따라서 이러한 유해 이동 코드를 차단하기 위한 여러 가지 방법 즉, Firewall이나 Code Signing, SandBox, Playground등과 같은 보안 메커니즘이 제안되어졌으나, 이러한 보안 메커니즘들은 이동 코드들에 대한 유해성 여부를 판단할 수 없고 또한 제한적인 실행으로 이동 코드의 효율성을 저하시키는 단점들을 내포하고 있다. 본 연구에서는 유해한 이동 코드를 진단.분석하고 이동 코드 실행을 탐지.차단 할 수 있는 탐지 소프트웨어를 개발하고자 한다.

  • The purpose of this study is to investigate the relationships between socio-economic position(SEP), environmental exposures, and health of older people in Korea. This study used the data from 'Environmental Exposures and Their Health Effect in Korean Elderly Population'. The sample includes a total of 563 elderly people who were 60 years of age or older. Data on SEP, environmental exposure, and health impact were collected and analyzed using descriptive statistics and multivariate regressions. As a result, study participants' SEP including age, family type, monthly expenditure, type of house, and region was significantly associated with environmental exposure. Also, while adjusting for SEP, environmental exposure such as allowing indoor smoking was associated with self-rated health and depression of study participants. The study findings showed inequality in environmental exposure and health outcomes by SEP in Korean elderly. Environmental exposure was associated with health outcome even after adjusting SEP, and this implied that environmental exposure could be a critical factor in explaining heath inequality by SEP. Further studies are necessary to better understand the causal relationships among SEP, environmental exposure, and health outcomes.

  • 인터넷의 급속한 발달과 이미지 콘텐츠 개발 기술의 발달로 현재 누구나 쉽게 이미지 콘텐츠의 공유 및 배급이 용이해졌다. 그러나 이로 인해 누드나 포르노와 같은 불건전한 유해 이미지들의 접근 역시 쉬워지고 있다. 특히, 스마트 폰이나 스마트 TV 등 멀티미디어 기능이 가능한 휴대장치 및 단말기의 비약적인 발전으로 인하여, 언제 어디서나 우리들은 유해 이미지의 노출되어 있다. 따라서 유해 이미지 시청이 적당하지 않은 연령층까지 무방비 상태에 놓여 있기 때문에 이를 막을 수 있는 시급한 대책이 요구되고 있다. 본 논문에서는 이중 피부 화소 검출에 이용하여 인체 영역 검출해내고 이것을 이용하여 유해 이미지 분류를 위한 방법을 제안하고자 한다. 일반적으로 피부 화소 검출 기법은 오차율을 가지고 있기 때문에 정확한 검출이 힘들다. 따라서 우리는 검출에 대한 강도를 조절하여 이중으로 피부 화소를 검출하여 좀더 정확한 피부 영역을 획득한다. 또한 기존의 방법들은 대체로 일차적인 피부 영역 검출에 초점을 둔 반면, 유해 판별의 주된 기준이 되는 가슴이나 성기, 엉덩이 등을 좀 더 중점적으로 찾으려 하지 않았다. 따라서 본 논문에서는 검출된 피부 영역에서 유해 부위를 좀 더 집중적으로 찾아 유해 판별 성능을 높이는 방법을 제안하고 실험으로 증명을 하고자 한다.

  • This study has assessed the industrial human toxicity index by means of toxic substances emissions in South Korean industry. The data used in analysis are the 146 kinds of the toxic chemicals emissions and final demands, total outputs in the input-output table. As a results, human carcinogenic index was $11.86198{\times}10^3$ for overall industries, and $0.26360{\times}10^3$ for average. The industries of higher human toxicity index can be ranked as follows: Mother vehicles and parts (7.85033) > Pig iron and crude steel(4.57409) > Primary iron and steel products(4.36668) > Other transportation equipments and parts(3.43293) > Inorganic basic chemical products(2.64379), etc. Such result can be considered as the priority order of regulation based on industrial characteristics, when the demand and industrial policies should be carried out for the deduction fof toxic substances.

  • The purpose of this study was to understand the dental hygienist's perception of dental materials and to understand the safety status of harmful chemicals. The study was conducted from January to February 2015 for 250 dental hygienists working in Gwangju Metropolitan City. as a result, the degree of recognition of MSDS for dental materials was higher with age (P <0.05) and higher in dental hygienist (P <0.001) working at dental hospital. (P <0.001), and the factors affecting the perception of first aid treatment were positively correlated with experience of hazard education (P <0.001). Therefore, by understanding the MSDS awareness of dental materials by dental hygienists and the safety situation in the handling of hazardous chemical substances, we provide basic data for establishing proper recognition of safety in the handling of harmful chemical substances and developing educational programs to prevent accidents.

  • This study compares the safety of nail products by reviewing domestic and foreign literature for preparing a safety management plan for reduction of human body exposure to hazardous substances that occur in nail products. We analyzed the cases of exceeding the limit value of hazardous substances. In domestic artificial nail adhesive and nail tip, toluene content was 40.3 times higher than the standard value, chloroform was 22.8 times, and antimony was 15.4 times. In developed countries, it is obligatory to provide material safety data and workplace ventilation equipment through various policy researches. However, there is no safety standard in Korea. Therefore, if the regulations for safety management should be established with each characteristic of nail product, work environment, workers, and consumers, and the awareness of hazardous substance cosmetics should be improved through development and dissemination of various educational programs, it can contribute to disease prevention and health promotion.

  • The rapid growth in areas related to IT is bringing about benefits and dysfunctions of informatization and harmful information on the Internet. It exerts evil effects on adolescents' mind and hampers their development of personality. The present study purposed to analyze the state on harmful information on the Internet, and to propose various educational plans for elementary school students. For these purposes, we analyzed the current state of harmful information by reviewing various literatures and previous researches, suggested the definition and types of harmful information based on previous researches in this study. In addition, we analyzed the state on harmful information of elementary school students by making a comparative analysis various researches about the state of harmful information; and based on this, various educational protective plans were suggested for elementary school students, teachers and parents. The proposed educational plan can be used for organizing education curricula of IT ethics, education programs for teachers and parents.
