We established a top-down methodology to estimate carbon footprint as national mean value (reference) with the statistical data on agri-livestock incomes in 2007. We also established LCI (life cycle inventory) DB by a bottom-up methodology with the data obtained from interview with farmers from 4 large-scale farms at Gunsan, Jeollabuk-do province to estimate carbon footprint in 2011. This study was carried out to compare top-down methodology and bottom-up methodology in performing LCA (life cycle assessment) to analyze the difference in GHGs (greenhouse gases) emission and carbon footprint under conventional rice cultivation system. Results of LCI analysis showed that most of $CO_2$ was emitted during fertilizer production and rice cultivation, whereas $CH_4$ and $N_2O$ were mostly emitted during rice cultivation. The carbon footprints on conventional rice production system were 2.39E+00 kg $CO_2$-eq. $kg^{-1}$ by top-down methodology, whereas 1.04E+00 kg $CO_2$-eq. $kg^{-1}$ by bottom-up methodology. The amount of agro-materials input during the entire rice cultivation for the two methodologies was similar. The amount of agro-materials input for the bottom-up methodology was sometimes greater than that for top-down methodology. While carbon footprint by the bottom-up methodology was smaller than that by the top-down methodology due to higher yield per cropping season by the bottom-up methodology. Under the conventional rice production system, fertilizer production showed the highest contribution to the environmental impacts on most categories except GWP (global warming potential) category. Rice cultivation was the highest contribution to the environmental impacts on GWP category under the conventional rice production system. The main factors of carbon footprints under the conventional rice production system were $CH_4$ emission from rice paddy field, the amount of fertilizer input and rice yield. Results of this study will be used for establishing baseline data for estimating carbon footprint from 'low carbon certification pilot project' as well as for developing farming methods of reducing $CO_2$ emission from rice paddy fields.

The purpose of this paper is to analyze the sector-specific greenhouse gas reduction implementation strategies priority using the multi-criteria analysis methods (AHP and Feedback ANP). Our analysis demonstrates that the highest priority among the evaluation criteria is given to the feasibility compared to the efficiency and the effectiveness in most of the sectors. In the public and the building sectors, it has been found that the governmental driving force is absolutely crucial in technological dissemination and diffusion. The results and the main findings are as follows. Firstly, the priority of the policy evaluation criteria has been changed by analysis methods. Secondly, the total weight and the priority of each sector's alternatives also have been changed. Finally, the priority of the alternatives for criteria has been changed by the analysis methods.

The purpose of this study is to explore the effect of perceived job insecurity on job crafting behaviors among employees from two different cultures: Jamaica and South Korea. Growth needs strength was also examined as a moderating variable on the job insecurity/job crafting relationship. This study collected 102 data samples from working individuals from Jamaica and 98 from South Korea. The Exploratory Factor Analysis (EFA) and the hierarchical regression analysis were used in order to analyze the data. Statistical analysis was performed using SPSS 24.0. Our research results indicated that perceived job insecurity has a significant effect on employees job crafting behaviors. The relationship between perceived job insecurity and job crafting behaviors differs based on culture. In addition, employees growth need strength moderates the relationship between the two variables. Although this study has some limitations, it contributed to the stress-coping literature by showing that individuals will engage in coping behaviors when they perceived job insecurity in the organization. In addition, culture and individual drive or need for growth plays an important role in how individuals cope with perceived stress or uncertainty.

This study is conducted to provide empirical evidences which support that the problems of social isolation and loneliness of elderly can be alleviated by intervening the inter-generational relationship of the elderly by means of active ageing policy. The major empirical challenge to address this question is the possibility of selection bias caused by reversed causal relationship. To address this challenge, I constructed comparison group with 'Eligible Non-Participants' (ENP), and used instrumental variable method to estimate the empirical model. My findings indicate that inter-generational relationship, both in the aspects of economical solidarity and associational solidarity, is significantly improved as time use pattern of the elderly becomes more active. The improvement effect is intensively observed for the group of elderly who do not live with their adult children. The important policy implication of these findings is that the improvement of inter-generational relationship can be added as a new benefit of active ageing policy.

This study aimed to improve the understanding of the qualification recognition system between Korea and Russia and to provide a way to help in the conclusion of the agreement on the qualification recognition in higher education through discussing related issues. To this end, we examined the recognition of academic qualifications in Korea and Russia, analyzed the status of mutual recognition of qualifications in higher education, and finally pointed out the issues raised and suggested ways to improve them. In the discussion of the qualification agreement, the issues are: first, whether the level of the agreement should be an intergovernmental agreement or an inter-institutional arrangement; Second, what is the scope of the agreement, and, third, with regard to the question of universality of the application of mutual recognition, whether this agreement can be universally applied to all Russian federal entities at the conclusion of the agreement. This study suggested that the mutual recognition agreement be concluded at a comprehensive and general level, and the qualification should be limited to academic qualifications, and the universality of the mutual agreement should be specified. Based on the results of this study, we proposed the necessity of regular and continuous discussions between the experts and government officials of the two countries in order to establish the system of the mutual recognition agreement and implementation process between Korea and Russia.

This paper examines how a social investment approach can be applied in a comparative analysis of childcare arrangements. We compared changes in Sweden, France, Germany, the UK, Japan and Korea during the 2000s, focusing on four dimensions of social investment: activation, gender equality, quality of care, and the degree of state's intervention in the family. We considered leave systems and the number of children enrolled in formal care and education facilities as indicators for labour market activation. For gender equality, women's position in employment is considered with respect to labour market participation rates, proportion of permanent employment, and wage-sex ratio. Quality of care concerns child-to-staff ratio and care provided with government quality control. The state's intervention was measured as social spending on families as proportions of GDP and total social spending. Our analysis provides empirical evidence that Sweden and France are pioneers in this arena and that the UK, Germany, Korea, and Japan are path-shifters in their care paradigms, albeit to varying degrees. Is the social investment approach an adequate paradigm for care? In a normative sense, this approach has potential. However, the following issues remain unaddressed: gender equality should be achieved through an expansion in good-quality jobs, fathers should be encouraged to take on childcare duties, and families should have universal access to good-quality childcare services controlled by the government.

The objective of this research is to depict examples of how a company could derive the skillset areas with the highest priority when analyzing the skill set requirements of human resources, based on the skillset requirements that are unique to each work site. For this purpose, a survey was conducted for each of the job categories for new employee in A company. The analysis results showed that in 32 out of the 34 areas, the gaps between the current levels and the expected levels were statistically significant. For employees of company A, the following 7 areas were determined to be the key job competencies with the highest priority: document creation skills, diagram creation skills, thinking skills, problem solving skills, time management skills, technology comprehension ability, and task comprehension skills. The required job competencies with the highest priority were found to be different for each job category. As a result of this research, the priority rankings of skillset requirements for each job category in company A could be determined, along with the implications for HRD/HRM and other companies.

기후변화에 관한 정부간 협의체(International Panel on Climate Change, IPCC) 4차 보고서에는 21세기말 지구의 평균기온이 최대 $6.4^{\circ}C$ 까지 더 상승할 것으로 전망하였다(IPCC, 2007). 지구의 평균온도는 지난 100년 동안 $0.74^{\circ}C$ 상승하였으며 그중 0.45%는 최근 25년간 상승한 것이며 이것은 지난 100년 보다 2.4배나 빠르게 상승하고 있는 추세이다. 우리나라의 경우 기온이 전 지구평균기온에 비해 2배 이상 높은 $1.5^{\circ}C$정도 상승 하였다. 또한 온실가스 증가 속도는 다른 나라에 비해 빠르게 진행되고 있으며, 1990년에서 지난 2001년간 다른 OECD국가들과 비교했을 때 가장 빠르게 증가하고 있을 뿐 아니라($CO_2$배출량은 OECD국가 중 10위) 현재와 같은 에너지 다소비형 산업구조와 소비패턴으로는 온실가스 배출량이 감소할 가능성은 낮은 것으로 분석된다. 따라서 우리나라의 경우 다른 국가에 비하여 기후변화에 취약한 위치에 있고 민감하게 반응함에 따라 미래 기후변화에 대한 영향은 우리나라 농업수자원에 큰 영향을 미칠 것으로 판단된다. 본 연구에서는 기상청에서 제공하는 MM5 기상자료를 이용하여 농업용저수지 필요저수량 변화를 예측하였다. MM5 기상자료는 충남 서산관측소 과거 관측자료를 이용하여 편의보정을 거쳐 재추출하였다. 생성된 자료는 물수지분석 입력 자료로 구축하여 충남에 위치한 고풍저수지에 대하여 필요저수량변화를 예측하였다. 그 결과 기온상승으로 인한 실재증발산량은 676mm에서 717mm로 41mm가 증가하였으며, 소비수량 또한 1,617mm에서 1,659mm로 42mm 증가하였다. 유효우량은 2020s는 520mm 이였으나 2080s는 533mm으로 13mm 증가한 것으로 분석되었다. 본 자료를 이용하여 고풍저수지의 필요저수량을 분석한 결과 2020s, 2050s, 2080s 각각 31.2%(3,538.9천$m^3$), 16.0%(1,489.7천$m^3$), 26.6%(2,834.5천$m^3$)가 부족한 것으로 예측되었다. 이는 강우량은 증가하나 기준년도에 비하여 5월 8월이 낮게 예측된 것이 가장 큰 원인으로 분석되었다. 따라서 소비수량은 증가하지만 유효유량의 부족으로 필요저수량이 부족한 것으로 예측되었다.

Through an examination and analysis of straight bills of lading and sea waybills in the context of English, U.S.A and Korean law, and relevant international conventions on maritime transport, the following results were obtained: Prior to the enactment of U.K.'s the Carriage of Goods by Sea Act in 1992, straight bills of lading had functional differences between countries. However, after the enactment of this law, negotiable bills of lading obtained the same legal status and functionality in both Korea and the United States, as well as in the UK. As for sea waybills, all three countries treated them with the same contractual and legal status. In other words, they serve as receipts for the transported goods and act as evidence of the maritime transportation contract. Nevertheless, they are non-negotiable, and the delivery of goods can be made to the consignee or their agent based on their identity. However, the transfer of ownership rights over the goods or acquisition of legal rights against the carrier cannot be achieved through the transfer or endorsement of Sea Waybills.
