Colon cancer is the third highest cause of death in Korea. Known dietary causes of colon cancer include a diet rich in fat and red meat as well as inadequate intake of dietary fiber, fruits, and vegetables. Therefore, recent research has focused on the anticancer effects of natural products. Opuntia humifusa is a type of prickly pear that is known to contain biologically active compounds that can be used in the treatment of diabetes mellitus, arteriosclerosis, and hyperglycemia. The aim of this study was to determine whether or not O. humifusa extract affects proliferation, cell death, and DNA fragmentation in human carcinoma HT-29 cells. O. humifusa is rich in carbohydrates, minerals (Mg, K, and Ca), and total phenolics. HT-29 cells were treated with extracts of O. humifusa at concentrations of 0, 0.25, 0.5, 1, and 2 mg/mL for 24 or 48 hours. O. humifusa extracts inhibited HT-29 cell growth in a dose-dependent manner. Hoechst 33342/PI double staining and Comet assay were performed to observe changes in nuclei of cancer cells undergoing cell death. The results of both tests showed that O. humifusa extract induced cell shrinkage, DNA fragmentation, and chromatin condensation dose-dependently in HT-29 cells. The results of this study suggest that O. humifusa extract inhibits the growth of HT-29 via induction of DNA fragmentation and chromatin condensation.

In 2002 Republic of Korea successfully launched a self-made mined proportion rocket and it is expected that she will be able to have own space launching system by 2010. According to Article 14 of the Space Exploration Promotion Act, a new law should be established to impose the limit of compensation for the damage by space accident. Therefore, The Space Accident Liability Act was passed in Korean Congress on Nov. 22, 2007 and it will be enforced in six months. The purpose of this Act is to provide reparation for the damage of the third parties that a launch causes; and the Commonwealth should be insured against any possible space accidents to pay for such a damage. Here space accident means the damages to our life, body, and properties from the launching of space objects. There should be an actual loss to establish the compensation of Liability Act. Article 2 in Liability Act defines "damage" as follows: the term "damage" means loss of life, personal injury or loss of or damage to property of persons. Physical and material damages are included in the conception of damage. The meaning of a launching includes any test launch and launch for a real arrangement which will ultimately provides a wide range of compensation. Article 4 indicates that absolute liability should be imposed in compensating for damage by space accidents. Article 4 also indicates that a launching party should be absolutely liable to compensate for the damage caused by its space object on the surface of the Earth. In general, liability stands where fault is. But if the activity is ultra-hazardous and causes serious harm, the individual needs to compensate for the damage unlimitedly. Because of the many launchings for the Seattleite launching, a launching organization is obligated to the liability insurance in preparation for the space accidents. According to the Article 6 of Space Accident Liability Act, to be insured for the compensation for damage is obligatory. It says: "In accordance with Article 11 in the Space Exploration Promotion Act, the person who wants to receive an approval f3r launching needs to be insured in compensation for the possible damage by space accidents.

Is there my relationship between a port information system and a port type? This paper aims to define its relationship through a study on the port types of advanced countries and their information systems. In terms of port ownership and its governing body, the port type can be divided into 4 types: state-run, public corporation, local government-run, and private ownership. According to the port type, the major activities of ports are different. In the case of a state-run and local government-run port, they put emphasis on the function of administration, but a public corporation and private ownership stress the importance of customer services. The study results of the mutual relationship of a port type and an information system show that the state-run and local government-run ports have a good administration-oriented system, and public corporation and privatized ports have an excellent customer-oriented community system and e-business system. The differences in the information system by port type provide an important suggestion to the improvement of information system of Busan Port Authority. As Busan port has been transformed from a state-run type to a public corporation, a new port information system has to be followed. Accordingly, this study has suggested a three-stage development plan: The first is a mirroring stage of stabilizing the port management, the second is a cooperation stage of enhancing customer services through the establishment of a community system, and the third is an e-business stage of developing a profit system in order to create value added.

Assesment of 30 nutritional minerals and 8 toxic elements in hair are very important not only for determining adequacy, deficiencies and unbalance, but also for assessing their relative relationships in the body. A test has been developed that serves this purpose exceedingly well. This test is known as tissue mineral analysis(TMA). TMA is very popular method in hair mineral analysis for health care professionals in over 46 countries' medical center. However, there are some problems. First, they do not have database which is suitable for korean to do analyze. Second, as the TMA results from TEI-USA is composed of english documents and graphic files prohibited to open, its usability is very low. Third, some of them has low level database which is related to TMA, so hairs are sent to TEI-USA for analyzing and medical services. it bring about an severe outflow of dollars. Finally, TMA results are based on the database of american health and mineral standards, it is possibly mislead korean mineral standards. The purposes of this research is to develope the first Intelligent Medical Expert System(IMES) of TMA, in Korea, which makes clear the problems mentioned earlier IMES can analyze the tissue mineral data with multiple stage decision tree classifier. It is also constructed with multiple fuzzy rule base and hence analyze the complex data from Korean database by fuzzy inference methods. Pilot test of this systems are increased of business efficiency and business satisfaction 86% and 92% respectively.

Objectives: This research is part of a study to be conducted over five years starting from 2017 by the Ministry of Environment on the development of technologies to evaluate the impact of chemical accidents on the human body. Methods: For this research, a five-stage specific study method was developed. Results: In brief, the developed health risk assessment method can be summarized as follows. First, a health risk assessment system was built based on the guidelines set forth by the USA NRC/NAS. Second, based on the disease manifestation theory, the health risk assessment method was divided into 1) a carcinogenic health risk assessment method focused on all carcinogens except non-genotoxic carcinogens and 2) a non-carcinogenic health risk assessment method focused on noncarcinogens including non-genotoxic carcinogens. Third, the detailed contents of the health risk assessment method were developed in four stages(hazard identification, dose-response assessment, exposure assessment, and risk determination) through theoretical consideration of the assessment of the level of health risk related to chemical exposure. Finally, a health risk assessment methodology, classified into stages to address acute, subacute/subchronic, and chronic conditions was developed after considering the physicochemical behavior of hazardous chemicals upon implementation of countermeasures after a chemical accident. Conclusions: A method to evaluate the health risks related to toxic chemicals generated by chemical accidents was developed. This study was performed with the purpose of developing a mathematical health risk assessment method to evaluate the health effects of exposure to hazardous chemicals upon implementation of emergency countermeasures after chemical accidents.
