  • We analyzed the current research trends of living modified organisms (LMO) by questionnaires in the interest of making biosaftey laws and policies in Korea. We executed a pre-survey at the Crop Functional Genomics 2004 conference and obtained LMO research information from 423 LMO research organizations, including 32 national research institutes, 314 universities, and 77 industries. We found that the total 59 kinds of hosts including 26 kinds of plants, 15 kinds of animals, and 18 kinds of microbes were used for LMO research and E. coli was the most common host. The risk of the most experimental hosts was below a biosafety level of 1 (73.8%) and 2 (25.9%). LMO development use purpose was implemented in various developmental uses: 51.3% in test and research use, 19% in health and medical use, and 12.9% in agriculture use. The experiment product, waste product, and products of host for LMO development were 327.2, 223.6, and 13.5 in number of plants; 280.6, 52.4, and 8.7 in number of animals; and $8.3\;{\times}\;10^{11}CFU$, $7.7\;{\times}\;10^{11}CFU$, and $6.5\;{\times}\;10^{11}CFU$ in microbes in 2004. The survey results about how to possess the LMO were very unreliable, because only 10.6% of the researchers returned the questionnaires. Consequently, we strongly suggest the scientific organizations as well as scientists should have more interests in biosafety of LMO research and an LMO biosafety management system should be developed for Korea's future biotechnology.

  • In this study, we have investigated the shielding evaluation methodology for facilities using kV energy generators. We have collected and analysis of safety evaluation criteria and methodology for overseas facilities using radiation generators. And we investigated the current status of shielding evaluation of domestic industrial radiation generators. According to the statistical data from the Radiation Safety Information System, as of 2022, a total of 7,679 organizations are using radiation generating devices. Among them, 6,299 facilities use these devices for industrial purposes, which accounts for a considerable portion of radiation. The organizations that use these devices evaluate whether the exposure dose for workers and frequent visitors is suitable as per the limit regulated by the Nuclear Safety Act. Moreover, during this process, the safety shields are evaluated at the facilities that use the radiation generating devices. However, the facilities that use radiating devices having energy less than or equal to 6 MV for industrial purposes are still mostly evaluated and analyzed according to the National Council on Radiation Protection and Measurements 49 (NCRP 49) report published in 1976. We have investigated the technical standards of safety management, including the maximum permissible dose and parameters assessment criteria for facilities using radiation generating devices, based on the NCRP 49 and the American National Standards Institute/Health Physics Society N.43.3 reports, which are the representative reports related to radiation shielding management cases overseas.

  • In this Information Age, the needs for the performance evaluation is raising to increase the higher-thought ability for creativity and problem-solving, to improve the quality of the teaching-learning process. However, it is very difficult to carry out the authentic performance evaluation in our educational environment. Therefore, we design and implement the Performance Evaluation Processing System as one of the learning-teaching processes. We study the theoretical base of evaluation types and of learning-teaching methods, and inquire appropriate performance evaluation methods. Among the methods, we focus on the Report, a type of performance evaluation using the most widely in the Society. We constitute a basic form and design the evaluation system of the Report. The evaluation system consist of the teacher's module and the learner's module. Teachers make the form of report, provide it for learners and evaluate the report on teacher's module, Learners make out the report, submit it to the teacher and use it for presentation in class, on learner's module, The teacher and learner can apply this system as follows. The teacher can use the report that have been already made, or that make for themselves as a step for evaluation and they can evaluate learners by the submitted report. The learner not only can see their own result of evaluation but also can use ICT at their presentation.

  • Objective: This study is to develop a design and evaluation guide to the ergonomic design of the farm working convenient equipments in order for the elderly to use them easily and safely. Background: The aging population has already increased in farm villages. But due to the usage of the farm working equipments that did not reflect the characteristics and functional changes of aging, accidents and patients with disease are increasing. Method: The study investigated the functional changes and physical, cognitive, and sensuous characteristics of the aged. By determining the criteria for classification of the convenient equipments by crop, and by finding out the items necessary for the ergonomic design, a guide to this study is proposed. Results: It is obvious that the physical, cognitive and sensuous functions change as the aging process continues. Therefore, for the design and evaluation of Control Panel, Control Lever, Frame Size, Shape, and Equipment Weight that are the necessary items for the ergonomic approach for the farm working equipments, such characteristics have to be reflected. Conclusion: Through this study, a guide to the design and evaluation of convenient equipments for the farm works that reflected the aging characteristics and functional changes has been proposed. Application: The result of this study is to expect not only designers but also related specialists to make the best use of it.

  • The purpose of this study is to grasp the effectiveness of evacuation safety design by verifying the appropriateness of the standard of occupant load factor for residential buildings. To this end, the definition and current standard of occupant load factor for residential buildings were analyzed, and the problems of the current standard were clarified by interviewing professionals. In addition, changes in occupant load factor were examined by year based on statistical research, and evaluation on the current standard $18.6m^2/pers.$ was performed. As for evaluation methods, the need of redesigning of evacuation capacity was investigated by using evacuation simulation. As a result of the analysis, the most serious problem was clarification of the applicable standard for residential officetel, where the average occupant load factor was $26.1m^2/pers.$, which was not appropriate. However, as a result of evaluation on evacuation capacity, although there was no difference between statistical research results and the current standard in terms of evacuation capacity, when the standard for business facilities was applied to officetel, evacuation time doubled. Thus, this study suggests that when the current standard is applied to residential officetel, it is necessary to separate between residential use and business use.

  • Since its introduction in Korea, design VE has widely been used as a means to enhance values in the construction industry. However, a greater emphasis is still placed on cost reduction in approach attitudes and performance evaluations on the implementation of design VE. In this regard, this study presented a performance evaluation method for cost, function, and value of VE proposals. Numerical criteria on the increase and decrease of cost and function that can classify the value enhancement type of VE proposals were proposed based on the performance evaluation method. It is expected that the use of numerical criteria for the type classification of VE proposal, and cost and performance evaluation method proposed in this study will make it possible to conduct a clear and more intuitive evaluation of VE proposal. However, it is appropriate to use the numerical criteria as a guideline to apply the new performance evaluation method for VE proposals. Therefore, it is necessary to conduct a statistical analysis with a wider range of users after the repeated application of the findings of this study, and thus to carry out research for presenting the numerical criteria for various types of users.

  • To curb a rapid increase in expenditures for pharmaceuticals, the Korean government introduced a positive list system and a negotiation process for drug prices at the end of 2006. Economic evaluation of pharmaceuticals has begun to have a pivotal role in the listing and pricing of drugs for the Korean National Health Insurance. There are some points to discuss regarding the use of economic evaluation in the listing and pricing in the context of the Korean system. First, the listing and pricing processes have been fragmented, evoking complaints from pharmaceutical companies and delaying the access of new drugs to patients. Second, there is a concern that the positive list system may limit the range and availability of drugs for patients to choose for treatment. Third, the time schedule for de-listing of existing drugs may not be realistic. Fourth, it is not always easy to provide reliable evidence of cost-effectiveness due to a lack of materials. Fifth, there is no consensus on the range of the ICER (incremental cost-effectiveness ratio) acceptable to the Korean society. In conclusion, in the near future, it will be necessary to evaluate the achievements that the economic evaluation has provided to the Korean society.
