Geographical indications are signs which identify a good as originating in the territory of a specific country, region, or locality, where the quality, reputation or other characteristics of the product is essentially attributable to its geographical origin. Korea has implemented geographical indication system through its Agricultural Product Quality Control Act since 1999. This research analyzes the impacts and implications of geographical indications on a particular cultural industry in a region using a case study of Boseong green tea which is the first product that was officially registered as a geographical indication in Korea. The results show that the geographical indication has contributed to the promotion of green tea industry in Boseong not only through increase of production but also through development of tourism. The implication is that a geographical indication can be used as an effective method to cope with trade liberalization in terms of agricultural policy. Another implication is that a geographical indication provides an efficient tool for place marketing.

In Korea, a good recycled product (GR) certification system was introduced in 1997 to improve resource and energy use efficiency. However, in industry and society, recycled products are not used well because of the lack of awareness of recycled materials. In this study, the status of domestic and international quality standards for nickel materials was investigated, and the purity and electrochemical properties of nickel sulfate prepared from ore and nickel sulfate recovered from waste lithium-ion batteries were evaluated during the electroplating process. As a result of the test, it was found that there is no quality difference between recycled nickel sulfate and high-purity nickel sulfate reagents when used in the electroplating industry.

In this paper, I developed a assesment indicator to evaluate SW program developed by students in SW education. The SW education carry out in elementary school, middle school and high school from 2016. But the assesment indicator to evaluate SW program had not been developed until now. Therefore, I tried to develop the assesment indicator that have harmoniously educational characteristic and SW qualitative characteristic. First of all, I had set the 15 attributes for assesment and developed the 36 criteria for 15 attributes. And the validity of 15 attributes and 36 criteria for assesment had been reviewed by 39 SW educational experts. As a result, the 15 attributes and 36 criteria for assesment were determined to which that have validity. I expect that the assesment indicator developed in this paper will raise the reliability of evaluation in SW education. And the assesment indicator may be used at SW competition conference for teenagers.

The generation of construction waste has increased continuously in the recent years, becoming an important social issue. In this paper, the generation and treatment of construction waste in Korea was reviewed and a comparative analysis was performed between Korea and developed countries to suggest some efficient recycling strategies. The generation of construction waste has increased 4 times from 10 million ton/yr in 1996 to 40.3 million ton/yr in 2002. Of the construction waste generated in 2002, concrete debris waste occupied 60.4%. Approximately 14.5% of the construction waste is landfilled, 2,0% incinerated and 83.4% recycled, then the recycling rate might be relatively high. However, there is room for increasing landfill diversion. It is somewhat important to strenghten incentives for the outstanding recycling business. It is also needed to improve the recycled aggregate quality standard and impurity content standard. It is desirable to toughen the facility standard for the recycling aggregate business and the quality standard for the intermediate treatment business. Also, market for the intermediate product of the recycled aggregate should be activated. Finally, more recycling-oriented regulations governing the construction waste has to be developed with the efficient public education program.

This paper presents an experimental investigation on the sealing defects and cracks of O-rings and a valve packing of a gas valve for a LPG cylinder. O-ring in which stops a gas leakage of a liquefied petroleum gas is very important for a LPG valve safety. Valve packing is to open and close a gas flow port for supplying and charging a LPG fuel. The sealing performance of two sealing units ism related to the leak safety and long lift of a gas valve. The investigated results show that most of O-rings was failed due to a circumferential crack in which is caused by partial press bonding failure near the partition zone and an excess compression rate. Some of the O-ring failure was originated by an extrusion of an excessive leak pressure of a LP gas. Thus, this paper strongly recommends a tight quality control and a safety guarantee system of O-rings and valve packing to guarantee a leak safety and to extend a service lift of a gas valve. At the end, a warranty policy of the sealing units should be adopted for increasing a product quality and safety of a gas valve.
