  • As a result of analyzing the domestic and foreign HACCP systems, advanced countries mandated HACCP system on all foods to strengthen food safety management and USA, EU and China do not apply small-scale HACCP system. Looking at the cases of food safety accidents in Korea and the non-compliance rate of HACCP certification evaluation by size, the accident rate of companies without HACCP certification was 31.2% higher than that of companies with HACCP certification. The nonconformity rate of food inspection standards was analyzed to be 89.0% higher than that of HACCP certification companies. Based on the international trend of food safety management and the frequency of food safety accidents, it is proposed to gradually expand the mandatory application of HACCP system in Korea to all foods, and to change the small-scale HACCP standard from less than 500 million Korean won or 21 employees to less than 500 million Korean won.

  • Recently, ESG management has become a global trend, receiving increasing attention from stakeholders such as consumers, investors, and governments, as regulations related to ESG disclosure and supply chain due diligence have been strengthened since the United Nations Principles of Responsible Investment (UN PRI) was announced in 2006. ESG is an acronym for the environment (E), social (S), and governance (G) and is accepted as a key factor for the continuous survival and growth of a company. As a result, there are over 600 ESG management evaluation indicators operated domestically and internationally, and numerous global initiatives have emerged. Korea's Ministry of Trade, Industry and Energy also announced "K-ESG Guidelines (December 2011)" and "K-ESG Guidelines for Supply Chain Response (December 22)" to help SMEs introduce ESG management and respond to supply chain due diligence. However, small-scale manufacturing companies with poor financial, human resources, and technological capabilities face significant challenges in introducing ESG management. Accordingly, this study aims to examine the current status of ESG management adoption in small-scale manufacturing companies with less than 150 people in Korea and propose activation plan ESG management based on the diagnostic requirements of the "Supply Chain Response K-ESG Guidelines."

  • Animal in dustry in Korea urgently needs the domestic introduction and the industrial a, pp.ication of embryo transfer technique. Namely, this technique can be utilized effectively, as means of the improvement of livestocks, as means of the increase of meat production, as means of substitute for the livestock import, and dissemination of new breed. However, as this technique avaliable in our country is remaining initial stage, we can not make use of the technique industrially unless we make much improvement as follows; induction of superovulation, non-surgical recovery of embryos, synchronization between the estrus such cycles of donor and recipient, non-surgical transfer of embryos, etc. Simultaneously, the basic studies such as harvesting oocytes from ovary, in vitro culture of oocytes, in vitro capacitation of spermatozoa, cloning by culture of blastomeres and transfer of nuclei, sexing embryo, etc. should not be neglected in order to make the technique of embryo transfer more simple and convenient. For the success of these studies, universities, national and public institutes, large scale cattle farms, and small scale cattle farms should cooperate each other. For instance, universities undertake basic researches, and the national and public institutes a, pp.y the results of the researches to animal industry along with cooperation by large scale cattle farms. By the help of the cooperative organizations, the technique relevant to our environment and farm condition may be able to be finalized, and to be a, pp.ied to samll scale cattle farm. Consequently, being served to stimulate animal productivity, this technique can be contributed to the development of livestock industry in Korea.

  • Recently, according to developing industry and life style, power consumption have been increased year after year. Currently these much power demand from power consumer is weakening the allowable power reserve margin in summer. As one of the remedies about this problem, the small scale utility interactive photovoltaic system(UIPVS) is considered for auxiliary power source. For this system one of problems to be solved technically, system operating power factor. Generally in case of small scale system, system is operated in unity power factor. But this unity power factor operating mode decrease power factor viewed from utility because UIPVS supply active power to utility. Therefore this paper propose UIPVS with power factor correcting function and this system is analyzed.

  • Purpose - The Korean government has revised the distribution industry development law to regulate large-scale retailer operations to protecting medium- and small-scale retailers and traditional markets. According to the revised law, large-scale retailers must follow regulations on operating hours and compulsory store closures two days per month. Based on the revised distribution industry development law, most local governments regulate operation hours and they have adopted compulsory closure programs for large-scale retail stores. However, it is argued that fresh food producers suffer from a decrease in sales based on the compulsory closure of stores operated by large-scale retailers. Large-scale retailers reduce their fresh food orders from agricultural and fishery producers because of the compulsory store closures. Fresh food producers also suffer from a decrease in prices because reduced orders lead to a decrease in auction prices based on the availability of excess goods in wholesale markets. This paper investigates the effects of operation regulations for large-scale retailers on agricultural producers by surveying agricultural and fishery producer organizations. Research design, data, methodology - A survey was conducted on 117 producer organizations of fruits and vegetables, cereals, fisheries, and livestock products from September 10 to October 4, 2012. Survey items are annual sales, shares of sales accounted for by large-scale retailers, reduction of orders and prices from large-scale retailers, methods to deal with the sales reduction, unfair trade practices of large-scale retailers, opinion of the large-scale retailer regulations, and so on. The average sales of the sampled producer organizations are 13.7 billion won and the average share of sales accounted for by large-scale retailers is 35.4%. Results - Survey results show that the sample producer organizations' sales decreased 10.1% because of the compulsory closures of stores operated by large-scale retailers. It is estimated that the total sales of producer organizations decreased 371.2 billion won because of the regulations on the operation of large-scale retailers. In addition to the direct effect of a sales decrease due to order reduction, agricultural and fishery producer organizations suffered from the secondary effect of price reduction in wholesale markets. When orders from large-scale retailers decreased, most agricultural and fishery producer organizations shipped redundant products to wholesale markets, decreasing auction prices. It was estimated that the price received decreased 21.9% when sold in other marketing channels. As producer organization sales decreased, it was reported that the labor force employed by producer organizations also decreased by 15.1%. Therefore, we can conclude that the regulations for large-scale retailer operations resulted in negative impacts on agricultural producers. Conclusions - Although the sales reduction due to the regulations for large-scale retailer operations are not great, the cumulative effects due to the continued compulsory closure of stores operated by large-scale retailers could be great. This paper suggests governmental programs that could help agricultural producer organizations to find new and effective marketing channels such as direct marketing, farmers' markets, exports, Internet shopping, and so on.

  • After the industrial revolution, we have changed whole life-styles. This trend has brought a change in our eating style. Nowadays, the great number of people go out to eat-even three meals a day. As a result, the growth rate of food service industry increases day by day. Some restaurants are managed by the large scale company and others by the small scale ownership. Though developed countries are in the maturity step of the product life cycle in this field, we are in the growth step. We will hold the in 2002. A lot of tourists and the press will rush to Korea. They must have their meals at the restuarant. Therefore, we need more practice to satisfy them and to lead to successful management in this field. Also, we need an evaluation to qualify each business so that our food service industry does not decline compared to other country's. This study is trying to find how to evaluate and qualify each business in the various areas: service, the quality of food, the mood of the restaurant and so on. In addition, it includes the restaurant rating form.
