  • Purpose - This study aims to derive directions and implications for improving performance in operating agrifood export organizations by identifying significant performance impact factors. Research design, data, and methodology - A seemingly unrelated regression (SUR) model was estimated using data from a survey conducted among 120 exporters including 16 leading export organizations. In the SUR estimation, the export volume and price are used as dependent variables and securing the quantity of products ordered and exported, quality management, and marketing activities are considered as explanatory variables for the operation performance. Results - The amount of farmer education, the manpower in charge of marketing, and the interaction terms between whether or not they belong to a leading export organization and the item dummy for mushrooms have a significant impact on the export volume where the export volume is specified as a dependent variable. The export volume is greater with a greater amount of farmer education and greater manpower in charge of marketing from the perspective of quality management. When the export price is estimated as a dependent variable, the manpower in charge of marketing is shown to have a significant impact on the export price. Conclusions - The government needs to strengthen its support of the performance of agrifood export organizations. The analysis indicates that the education of and consulting with farmers, and the manpower number in charge of marketing are key factors in the operation performance of export organizations. Therefore, supporting the export organizations in expanding their human resources in charge of marketing can increase the export volumes for agrifoods. Given, however, that the export volume associated with joint payments, human resources specialized in quality management, and the amount of participation in export exhibitions are not significant factors, it is essential to improve the supporting policies for those areas. The manpower in charge of marketing from the perspective of marketing has a significant impact on both the export volume and export price. Thus, we identify this as the most important category that should be supported to enhance performance in export organizations.

  • Purpose - The purpose of this study is to examine whether social value-related expenditures can be recognized as intangible assets in financial statements. Design/methodology/approach - This study examined social values defined in the economic and management fields and analyzed whether the social values have the characteristics of intangible assets. For this, the general definition of social value was derived from the concept of social value covered in previous studies. Next, we reviewed the definitions and recognition requirements for intangible assets under the current accounting standards. Based on this, we tried to suggest new criteria and disclosure methods for reporting social value-related expenditures that are not currently reported in financial statements as intangible assets in the financial statements and notes. Findings - First, as a criterion for recognizing social value-related expenditure as an intangible asset, we propose a relationship between social value-related expenditure and enterprise value. Where social value-related expenditures have a statistically significant positive impact on corporate value, they are recognized as intangible assets. If social value-related expenditures have a statistically significant negative influence on business value, or the impact of social value-related expenditures on the enterprise value is not statistically significant, it is not recognized as asset. Second, new disclosure plans are proposed according to the combination of intangible assets by category and the relevance of enterprise value. After dividing social value-related expenditures into separate intangible asset categories, if social value-related expenditures have a statistically significant positive impact on corporate value, they are recognized as intangible assets in the financial statements. If expenditures have a statistically significant negative impact on business value, they should be recorded as essential notes. Finally, if the impact of social value-related expenditure on corporate value is not statistically significant, it should be listed as a supplement. Research implications or Originality - This study contributes to the concurrent research in that it is a priori study on whether social value-related expenditure can be recognized as an asset. This study suggests that the economic effect of social expenditure can be recognized in corporate financial statements, thereby providing companies with justification and effectiveness of social value-related expenditure.

  • The purpose of this study is to seek the application of IUCN categories of overlapping protected areas which is legally designated in South Korea. Different government departments in South Korea have managed and designated as protected areas. However, the protected areas due to different management agencies can be confused with restricting behaviors and supporting residents. The IUCN presents the reasonal standardization classifying the protected areas which could be applied all over the world. Six categories issued by the IUCN could be applied to deal with the problems of the overlapping protected areas. We suggested the application of the IUCN categories compared with legal frame in South Korea. Most areas are overlapped in designation, but the areas are important for ecology and landscape. Moreover, each protected areas in South Korea have zone districts. Comprehensively considered all these things, we made rationale matrix correlated with the IUCN categories and the zone districts of the protected areas in South Korea. For the result of this study, this matrix could be helped to the application of the IUCN categories in domestic protected areas. Although the protected areas has been recognized as regulatory regions, it is expected to expand and sustain the areas based on the matrix.

Methods : The retrieving and analyzing period were from January 1995 to July 2006. Articles were collected by retrieving Pubmed database. Search terms were as follows; 'Acupuncture', 'Acupuncture & Meridian', 'Moxibustion'. After reviewing articles by our pre-defined criteria, Correlation was assessed qualitatively between contents of the final selected articles and those of Korea Institute of Oriental Medicine. Results : The number of acupuncture research articles have increased with higher rate since the year of 2000. In the field of medical devices, the articles were sparsely existed. The percentage of clinical acupuncture research articles was 75%. However, in the category of Korean investigators' researches, it was 46%. Publications by Korean investigators were concentrated to several specific journals of which their impact factor were below 1 point. Conclusion : There needs more qualifying studies in acupuncture studies which are represented by impact factor in Journal Citation Reports. It is necessary to research and develop the medical devices quantatively rating the outcome of acupuncture trials. The secondary research, such as, systematic reviews, meta-analysis, would be a key approach to evaluate the effectiveness and safety of acupuncture treatments. Moxibustion research would be noticeable in regard to its historical effectiveness and its variable indications.

  • 이 논문은 통신서비스의 규제정책이 역무통합이라는 규제정책의 변화와 함께 과거의 수직적 규제에서 수평적 규제체제로 바뀜에 따라 기존의 개별규제체제가 어떠한 형태로 변할 것이며, 이에 따라 통신망 투자에 어떠한 영향을 미칠 것인가를 분석한다. 역무통합은 진입규제와 행위규제를 분리하여 진입의 제약을 축소하고 행위규제의 유연성을 제고하는 효과를 가진다고 볼 수 있다. 따라서 역무통합 자체가 주는 직접적 효과보다는 상호접속 규제, 설비제공제도, 요금규제, 결합판매, VoIP 번호 이용 등 역무통합과 연계된 행위규제 개선을 통해 간접적으로 시장 파급효과가 나타날 것으로 예상된다. 본 논문에서는 먼저 기업수준에서 투자의사결정에 영향을 미치는 요소들에 대해 논의하고, 진입규제 완화, 상호접속, 요금규제, 망중립성 등의 개별규제가 투자결정에 미치는 영향경로를 분석한다. 마지막으로 정책에 대한 기본적인 가이드라인을 제안한다.

  • Modeling the consumer demand of fresh meat requires its distinct feature which other types of food product does not have. Most of the fresh meat products are likely to be unbranded, bought on a weight basis and affected by macro shocks such as seasonality, holiday effect and the disease incidence. Furthermore, consumers tend to purchase multiple categories of fresh meat in a week. Therefore, we apply a multiple discrete/continuous model on fresh meat consumption data to study the effect of macro shocks on fresh meat sales as well as of price change. As a result shows, Each fresh meat is relatively more likely to be bought in peak season of each fresh meat compared with imported pork which is set as a 'reference category' in this analysis. For clarity of the effect of disease incidence, we perform further analysis regarding the effect of livestock disease on fresh meat purchase probability. It shows that the avian flu in 2014 has strong negative impact on the purchase probability of chicken and the foot-and-mouth disease has negative impact on the purchase probability of pork and beef for part of outbreak periods.

  • This study was conducted to find out characterization of spatial distribution of birds observed in river areas. Our bird survey was carried out 4 times at 31 sites from January to September in 2011. A total of 1,609 accumulated individuals belonging to 59 species, 28 families and 11 orders were observed. In the result of spatial autocorrelation analysis using the richness index of the maximum counts of each sites, we confirmed that the distribution of birds in Namdaecheon river was clustered and the tendency of spatial autocorrelation was apparent. The area of each sites within a 200m radius was classified in four biotope categories such as agricultural land, forest, residential area and water area, and the spatial autocorrelation was analysed about four types. In the result of spatial autocorrelation analysis for four biotope categories, all types were showed the positive spatial autocorrelation, but the type of water area was higher than other types. The positive correlation was found between the water area and water birds in statistical significance. However, the forest birds had non-significance values. Therefore, it is appropriate to focus on water birds except for forest birds, when researches of bird distribution in river ecosystem is conducted. The number of bird species and individuals increased as the riverside of water area was to widen. Thus, if the areas of riverside offering the feeding and roosting area increase, it will be accommodated many birds. Also, the areas of riverside should be maintained naturally because it is an important habitats of birds. Our study area is on the outskirts the city of higher rates of forest and agricultural land, it may be unreasonable to apply our results to the whole rivers. If the research about the river flowing around the city will be conducted, it is expected to be useful to the relation study area such as ecological river's restoration.

  • 급속한 산업화, 도시화 및 경제성장으로 다양한 개발사업이 발생하였다. 다양한 개발사업으로 인하여 각종 오염물질이 발생하였으며, 발생된 오염물질은 자연적으로 형성된 물순환 시스템이 아닌 인위적으로 형성된 물순환 시스템으로 인하여 하천 및 호소로 직접 유입되어 수질이 악화되고 있는 실정이다. 강우시 다양한 토지이용에서 발생하는 비점오염원이 큰 원인으로 나타나고 있다. 본 연구는 강우시 발생하는 비점오염물질 처리를 위한 저류 및 침투기능을 포함하는 한국형 비점오염저감시설인 Eco-Bio Filter (EBF)를 개발하고자 한다. EBF 시설은 저류 및 침투기능을 포함하며, EBF Test-bed를 공주대학교 천안 캠퍼스 내에 설치하여 다양한 강우사상에 대하여 모니터링을 수행하였다. 현재 모니터링 결과를 활용하여 기술의 문제점을 분석하고 개선하는 과정이 진행되고 있으며, 본 연구에서는 개선된 EBF 기술을 제시하였다. 오염물질별 저감효율을 분석한 결과, 입자상 물질, 질소, 인, 중금속에 대하여 70% 이상의 높은 저감효율을 나타내었다. 이러한 연구결과는 향후 국내 강우특성에 맞으며 도시의 생태를 확장할 수 있는 새로운 비점오염기술을 개발하는데 기초자료로 활용될 것이며, 저영향개발(LID) 중 하나가 될 것이다.
