  • The physicochemical properties of solid wastes generated from seven highway service areas, four branch offices, and one construction site were analyzed in concert with air pollutants including heavy metals emitted from near-by small-scale incinerators. The amount of solid wastes generated from highway areas has been increasing with recent increases in the number of highways and passengers. Twelve incinerators examined in this study generally had capacity smaller than 100 kg/hr, most of which were equipped with cyclone for dust removal. It was seen that the concentrations of the gas-phase air pollutants (e.g., SO$_2$, NO$_{x}$, HCl and H$_2$S) were above the acceptable emission standards except one or two sites. CO concentrations at all incinerators were also higher due to incomplete combustion. In addition, particulate matters showed concentration six times higher at their maximum. The results of heavy metal analysis showed that the concentrations of Cu, Cd, and Ni satisfied the emission standards. whereas Pb at one site and Zn at five sites exceeded the standards. Cr measurement results indicated that 9 of 12 incinerators had higher values than the standard; especially one branch office showed nine times higher than normal concentration. In order to satisfy more stringent emission standards in the near future, it is necessary to install air pollution control system and to develop an intensified management plan.n.

  • In South Korea, smoke control systems are designed according to the fire safety standards NFSC501 and NFSC 501A. However, there is a problem in that the design values are incompatible when measuring the performance of the system after the design construction for calculating the leakage crack area described in the standards. Therefore, we compared the standards for smoke control systems from South Korea, Japan, and the United Kingdom. In South Korea, designs are conducted uniformly according to the NFSC 501A Manual, but in Japan and the United Kingdom, designs consider smoke temperature, duct loss, and fire floor air supply. Furthermore, they use larger values than in South Korea.

  • The light from the exterior considerably deteriorates the performance of displays including PDP (plasma display panel). Thus semi-conductor industries have developed a special optical film that can block or absorb the exterior light. In this paper, we propose a new inspection system for tracing the defects of the film. Our system is able to inspect a $1.5\;m\;{\times}\;1\;m$ area for 10 sec with $127\;{\mu}m\;{\times}\;50{\mu}m$ spatial resolution.

  • Purpose: The purpose of this study is to introduce the development trend of international standard in the innovative management system and propose the application method of the standard for SME certification system. Methods: This study is based on literature studies and case studies considering the initial stage of development of standards as well as lack of domestic and international research examples. In the literature review, we focused on the characteristics of the innovation management system standards at the national, regional and global level. We examined case studies of Spain and Portugal as case studies. Besides, the evaluation items and certification status of domestic innovative SMEs certification were also searched to find out how to introduce them in Korea. Results: The results of this study can be summarized in three major points. First, new international standards of innovation management are being developed under the ISO management system standard and are currently in the DIS stage. Second, in the case of Spain adopting the national innovation management system standard, it has been reported that the innovation management system standard has a significant effect on the innovation ability and management performance. Third, it was not easy to establish a standardized innovation process between the innovation based on creativity and the standardized based product. The Oslo manual was not enough to provide enough guidance in this area. Conclusion: Companies that want to strengthen their organizational innovation capabilities from a management system point of view and Policymakers that want to plan the upgrading and integrated certification operating system of the domestic innovation SME certification need to consider the ISO 50500 series as a global level standard other than the Oslo manual.

  • Purpose: This paper aims to evaluate and reinstate preventative guidelines necessary for a sound academic journal (or academic conference) for the articles published by KODISA and its branch journals. As questionable or predatory academic journals and academic conferences are rapidly increasing, preemptively establishing preventative standards have become essential to obviate questionable academic activities. Research design, data and methodology: This is an analytical study that explores and examines research, publication ethics, and misconducts. For this purpose, research ethics related data in overseas and domestic academic journals have been examined and analyzed. Results: The issues identified from this research are as follows: enhancing the expertise of editor-inchief (no concurrent jobs for major and non-major area); clarifying the index; complying with the review policy (The review policy should be publicly announced); complying with anonymous review process; complying with 3 peer-review policy, complying with the publication policy as per field of study; avoiding conference hosting at holiday resorts unless unavoidable; complying with the planned programs and cancelling events if not feasible; following proper review standards and management for all journals, including the journals publishing large number of articles (all materials should be prepared in case explanatory data is required); complying with the marketing policy standards; complying with the impact factor; excluding personal solicitation; and complying with the general policy. Conclusions: Questionable and predatory academic activities by academic organizations and journals will continue, and it is the responsibility of the individual scholars to identify and reject these types of dubious academic activities. This study provides standards to prevent the possibility of questionable academic activities that have been conducted in the past. The analysis and findings will strengthen the continued efforts of KODISA as it strives to be a transparent, ethical, and professional academic association, and the association will continue to foster an academic environment that is well-respected by scholars and practitioners throughout the world.

  • This study examined the wastewater at a livestock farm, and found that the dairy wastewater from the milking parlor had a lower concentration than the piggery wastewater, and that it was produced at a rate under 1.3 ㎥/day in a single farmhouse. The amount of dairy wastewater was determined based on the performance of the milking machine, the maintenance method of the milking parlor, and the amount of milk production allocated for each farmhouse, not by the area. The results confirmed that both dairy wastewater treatment processes, specifically those using Hanged Bio-Compactor (HBC) and Sequencing Batch Reactor (SBR), can fully satisfy the water quality standards of discharge. The dairy wastewater has a lower amount and concentration than piggery wastewater, meaning it is less valuable as liquid fertilizer, but it can be easily degraded using the conventional activated sludge process in a public sewage treatment plant. Therefore, discharging the dairy wastewater after individual treatment was expected to be a more reasonable method than consigning it to the centralized wastewater treatment plant. The effluent after the SBR process showed a lower degree of color than the HBC effluent, which was attributed to biological adsorption. In the case of the milking parlor in the livestock farm, the concentrations of the effluents obtained after HBC and SBR treatments both satisfied water quality standards for the discharge of public livestock wastewater treatment plants at 99% confidence intervals, and the concentrations of total nitrogen and phosphorous in untreated wastewater were even lower than the water quality standards of discharge. Therefore, we need to discuss strengthening the water quality standards to reduce environmental pollution.

  • As "Made in Korea" has high branding power in the fashion industry, domestic clothing manufacturers also need to consider branding the country of origin. Therefore, the purpose of this study was to reconsider the need for a domestic certification system and suggest a direction by analyzing apparel origin certification systems operating overseas. The results of this study could be used for planning certification standards and operating methods suitable for regional characteristics and industrial environments when establishing a certification system for clothing produced in Korea. The case study subjects were Japan's J∞ Quality, USA's Made in New York, Italy's 100% Made in Italy, and France's Origin France Guarantee has been classified as certification criteria related to the country of origin include items related to the production process rate in the region and the production area for each production process/stream. Manufacturing technology and design are used for quality standards, safety, hygiene compliance, production facilities, and quality control and are applied to working environment standards. The certification system selects and operates standards according to each country's industrial environment, certification subject, and purpose. Therefore, when designing a domestic apparel certification system, a feasible promotion plan should be established that considers the current state of the domestic industry, which will serve as a driving force for the growth of the apparel manufacturing industry and an opportunity to increase the trust of global fashion consumers.

  • This study introduces a model of territorial analysis on Chungcheongnam-do Nonsan-chun valley area, which gives an example of a method of selecting the management area for non-point pollution source from land use to help eliminate its source. High discharge load per unit area signify high level of land ratio with high level of basic unit of development load (including factory sites, school sites, roadways), which mean that there are a significant level of urbanization. It is these areas with the examination of the water quality of the nearby river that should be considered as the management area for non-point pollution source. Thus, the management area for non-point pollution source should be sought in areas with high discharge load per unit area and high density of water pollution area. When level of drainage is high the pollution density level is relatively lower, and when the level of drainage is low the density level is relatively higher. The level of pollution from non-point pollution source is much lower with more water flowing through. The possible non-point pollution source areas that were selected with these standards were then examined with the distance from the river, the slope angle, land usage, elevation, BOD discharge density load, T-N discharge density load, T-P discharge density load, and were given a level one through five. Out of the possible areas Nonsan-si Yeonmu-eup Anshim-li was the densest area, and it was given level one. The level one area should be examined further with the field analysis to be selected as the actual management area for non-point pollution source.
