The shipping industry plummeted and was depressed due to the global economic crisis caused by the bankruptcy of Lehman Brothers in the US in 2008. In 2020, the shipping market also suffered from a collapse in the unstable global economic situation due to the COVID-19 pandemic, but unexpectedly, it changed to an upward trend from the end of 2020, and in 2021, it exceeded the market of the boom period of 2008. According to the Clarksons report published in May 2021, the decrease in cargo volume due to the COVID-19 pandemic in 2020 has returned to the pre-corona level by the end of 2020, and the tramper bulk carrier capacity of 103~104% of the Panamax has been in the ports due to congestion. Earnings across the bulker segments have risen to ten-year highs in recent months. In this study, as factors affecting BDI, the capacity and congestion ratio of Cape and Panamax ships on the supply side, iron ore and coal seaborne tonnge on the demand side and Granger causality test, IRF(Impulse Response Function) and FEVD(Forecast Error Variance Decomposition) were performed using VAR model to analyze the impact on BDI by congestion caused by strengthen quarantine at the port due to the COVID-19 pandemic and the loading and discharging operation delay due to the infection of the stevedore, etc and to predict the shipping market after the pandemic. As a result of the Granger causality test of variables and BDI using time series data from January 2016 to July 2021, causality was found in the Fleet and Congestion variables, and as a result of the Impulse Response Function, Congestion variable was found to have significant at both upper and lower limit of the confidence interval. As a result of the Forecast Error Variance Decomposition, Congestion variable showed an explanatory power upto 25% for the change in BDI. If the congestion in ports decreases after With Corona, it is expected that there is down-risk in the shipping market. The COVID-19 pandemic occurred not from economic factors but from an ecological factor by the pandemic is different from the past economic crisis. It is necessary to analyze from a different point of view than the past economic crisis. This study has meaningful to analyze the causality and explanatory power of Congestion factor by pandemic.

The purpose of this study is to classify the attitudes of Korean people regarding foreign workers and to analyze the influence factors. Analysis of the attitude difference and the influential factors utilized the SPSS ${\chi}^2$ test and multinomial logistic regression analysis using 2016 data obtained from the 'Koreans' Consciousness and Values'. Socio-demographic variables, national identity, and socioeconomic variables were used as explanatory variables. The attitude types (friendly, negative, and dual) of respondents were identified, and the influence of explanatory variables influencing these attitudes was identified. Analysis found they have a relatively generous stance on granting legal rights, while they are negative regarding the economic and social threats from foreign workers. As a result of analyzing the factors affecting attitudes, there are significant differences in each influence. However, negative attitudes and dual attitude concerning with negative legal rights found common to the influence of the factors of national identity. Gender and ratio of foreign workers were influential factors for dual attitudes with a high economic threat. On the other hand, socioeconomic factors reflecting the realistic conflict theory were not found to have any effect. The negative attitude of foreign workers in our society can be regarded as cognitive threats rather than realistic experiences or conflicts.

In the growing field of green marketing there are various psychological influences that can lead to green purchase behavior. An understanding of these influences can lead to greater green marketing effectiveness. The purpose of this paper is to analyze the effects of several value types, environmental attitudes, and preference for product attributes on green purchase behavior. To this end, a conceptual model has been proposed and tested for empirical verification with the use of a survey. Data collected from 266 Korean respondents are analyzed using path analysis. Results provide support for the proposed model, demonstrating positive links among universalism, environmental attitudes, preference for environmental attribute, and green buying behavior. It indicates that individuals with universalism as a preferred value type are high in their environmental attitudes and finally, tend to buy green products through their preference for environmental attribute. The mediating role of preference for price is not significant between environmental attitudes and green purchase behavior. The present findings, in addition, contribute the width of understanding of various proenvironmental behaviors by focusing on green purchase behavior and surveying with a Korean sample. The implications for the practices of green marketing are discussed.

The safety and health ledger system, which gives the responsibility of safety and health management for construction site workers to the construction project owner, was introduced as part of the overall revision of the Occupational Safety and Health Act. There is a need to explain the system's effectiveness in terms of economic feasibility to solve the execution problem of the system caused by low awareness and implementation rate. In this study, the economic effect of implementing the safety and health ledger system was analyzed using cost-benefit analysis based on the data discussed at the time of the introduction of the system. Results show that creating and managing the design safety and health ledger caused additional costs in implementing the system. As a result of comparing the cost of preparation and the direct and indirect benefits caused by the reduction of industrial accidents, the benefits were evaluated higher than the costs. Thus, it is thought that the safety and health ledger system reduces construction work accidents and generates economic effects.

토지문제(土地問題)의 심각성에 대한 사회적(社會的) 합의(合意)에도 불구하고 정부의 개입으로 시정되어야 할 구체적인 정책목표(政策目標)가 무엇인가에 대한 검토(檢討)는 부족한 설정이며, 이를 위해 지가상승(地價上昇)의 원인과 결과에 대한 실증분석(實證分析)을 시도한 예도 찾아보기 힘들다. 본고는 지가상승률(地價上昇率)과 일단의 거시경제변수(巨視經濟變數) 변화율(變化率) 사이에 Granger 개념의 인과관계(因果關係)가 존재하는가를 검증하고 그 현실적인 의미를 살펴보고 있다. 지가상승추세(地價上昇趨勢)를 변화시킬 수 있는 거시변수(巨視變數)는 통화량(通貨量), 민간건설생산(民間建設生産), 주가지수(株價指數)의 변화 등이며, 지가상승이 영향을 미치는 변수(變數)들은 주가지수(株價指數), 실질생산(實質生産) 및 민간건설생산(民間建設生産)의 변화(變化), 사채이자율(私債利子率)로 나타났다. 여기서 포착된 경험적 증거들은 인과관계(因果關係)의 작동경로를 설명하는 이론과 결합되어 발전되어야 할 것이나 우리의 분석결과로부터도 몇가지 정책적(政策的) 시사점(示唆點)을 끌어 낼 수 있다. 무엇보다도, 지가상승(地價上昇)을 거시경제현상(巨視經濟現像)으로 파악하는 것이 필요하며, 거시경제환경이 불안정한 경우 토지조세(土地租稅)와 같은 미시적(微視的) 정책수단(政策手段)이 지가안정 등의 정책목표(政策目標)를 달성하는 데는 뚜렷한 한계가 있다는 것이다. 지가상승(地價上昇)이 물가상승(物價上昇)을 가속화한다는 것도 중요한 점인데 통화긴축(通貨緊縮)과 같은 정책수단이 물가(物價)와 지가(地價)를 모두 안정시킬 수 있다는 점은 다행한 일이다. 또한, 건설생산액(建設生産額) 변화와 지가상승(地價上昇)간의 관계는 적극적인 개발투자(開發投資)가 장기적인 지가안정(地價安定)에도 도움을 준다는 쪽이므로 사회간접자본(社會間接資本)의 확충(擴充), 민간건설(民間建設)의 확대(擴大)가 지속적으로 이루어지도록 해야 할 것이다.
