  • The Changwon city which announced 2040 hydrogen policy vision is planning to establish the new hydrogen-centered city. The building of plant which is available to produce the 5 ton/day of liquid hydrogen is promoted as one of the projects in order to achieve the vision. However, the analysis in terms of local economic and environmental aspects is insufficient because this liquid hydrogen plant is the first in Korea. Therefore, in this study, the financial feasibility of the liquid hydrogen plant project was analyzed by reviewing the benefits of liquid hydrogen supply and environmental improvement, and the feasibility of this project has been investigated which is being built based on the hydrogen industrial plan of Changwon city.

  • The current method of rate adjustment is based on the evaluation of the financial performance of hospitals. The method has the disadvantages such as too complicated, expensive process as well as low reliability due to small sample size. This study, therefore, develops a new model for the rate adjustment with the use of the composite index. In addition to that, it examines the validity of the model by comparing the result of the new method with that of the conventional method. The idea of the new model comes from the Medicare Economic Index(MEI) on which physician fees for the Medicare patients are adjusted periodically in the United States. Medical costs are classified into three groups : labor costs, materials and other expenses. Labor costs are subdivided into physicians and other personnels. Materials are subdivided into drugs and others. Other expenses are subdivided into 5 items. Macro economic indices are selected for each cost item in order to reflect the cost inflation during the specific period. Then the composite index which integrate all items according to the ration of each item in the total costs is calculated. The result from the application of empirical data to the new model is very similar to that of the current method. Furthermore, this method is very simple and also to easy to get social concensus. This model can be replaced the current method based on the analysis of the financial performance for the adjustment of medical fees.

  • 우리나라의 주요 교역권은 아시아, 미주, 유럽 교역권으로 나눌 수 있다. 일반적으로 대량의 화물운송은 해상운송이 주를 이루지만 다른 지역과 다르게 유럽 교역권은 철도 운송이 가능하다. 또한, 중국의 성장으로 동북아 물류 중심지로서의 경쟁력이 약화된 우리나라는 지금의 경쟁구조와는 다른 방안인 철도운송에 주목할 필요가 있다. 이러한 배경 하에 본 연구에서는 한반도 종단 철도(TKR)와 시베리아 횡단철도(TSR)를 이용한 유럽 지역과의 운송 경로를 비교하여 경제성 분석에 주안점을 두었다. 분석의 요소로는 운송거리, 운송기간, 운송비, 추가비용을 중심으로 사용하였으며 분석 결과 6가지의 운송경로 중에서 TKR과 연계한 TSR(Route 1)이 경제적이라는 분석 결과가 나왔다. 따라서 향후 러시아 푸틴정부의 극동발전 전략에 대비하여 우리나라는 TKR과 TSR의 철도운송을 활용하는 것이 국가 경쟁력을 높일 수 있는 방안이 될 것이다.

  • 98. 2. 6 노사정 사회적 합의를 IMF 자금지원으로 인한 국가적 경제위기가 만들어낸 계기적 산물로 보아서는 합의구조의 향후 방향성과 견고성을 평가하는데 한계를 가질 수 밖에 없다. 따라서 본 연구는 '98.2.6 합의를 도출시킬 수 있었던 한국의 사회적 합의구조의 뿌리를 분석하여 역사적 연원을 밝혀 내었다. 이 과정에는 사회적 합의정신에 바탕을 두고 형성된 정치 사회적인 모델인 사민주의 또는 조합주의의 적용가능성을 분석하는 한편, 도니슨(D. Donnison)의 복지국가적 사회적합의 모델의 조건들을 한국의 역사적 관점에 입각하여 분석하였다. 위에서 도출된 사회적 합의의 역사성을 장애인, 사업주, 정부를 변수로 하는 장애인 고용정책에 적용하여 봄으로써, 사회정책과정에서의 사회적 합의모형의 설명력과 예측력을 분석하여 보았다. 분석 결과 장애인 고용 문제 역시 사회 문제의 한 부분이므로 진공 속에서 해결하기는 불가능하며 사회적 합의구조와 비슷한 구조인 장 사 정(障 事 政) 합의구조 속에서 좀더 효과적인 정책수행이 가능함을 추론할 수 있었다. 이에따라 IMF자금지원 이후에 새롭게 발생된 장애인 고용 정책상의 문제를 진단 처방해보는 것도 연구의 실천성을 평가해볼 수 있는 소득이었다.

  • This study provides basic data on how stress impacts the processed convenience foods purchase attitudes and the selection attributes of housewives. The stress consists of 3 factors, which were housework stress, family relation stress and economic stress. The processed convenience food purchase attitude consisted of 2 factors, which were peripheral influence purchase and conviction purchase. The processed convenience food selection attribute consisted of 4 factors, which were quality, convenience, packaging and price. Factor loading confirmation and reliability test were conducted, and the reliability was confirmed with Cronbach's alpha coefficients for all the factors exceeding 0.5. The high stress levels showed significantly high stress factors of housework, family relations and economic stress (P<0.001). The high stress group was shown to make purchases by recognizing peripheral influences (P<0.01). When the selection properties of processed convenience foods depending on different stress levels were examined, it was revealed that among the three groups, the low stress group least considered the price aspect (P<0.01). After deducting the factors, AMOS (Analysis of Moment Structure) was used to conduct the confirmatory factor analysis for verifying validity. The structural equation model was used to determine the path coefficient. From the processed convenience foods purchase attitude, the peripheral influence purchase had significantly positive (+) effects on convenience (P<0.05). Also, conviction purchase was shown to have significantly positive (+) effects on quality (P<0.05). Housework and family relation stress were shown to have negative (-) effects on processed convenience foods selection attribute, and economic stress was shown to have positive (+) effects, although no significant relationships were revealed.

  • 이 연구의 목적은 최고지가에 대한 비율로 도심의 경계를 설정하는 방법을 검토하고 원도심과 신도심의 특성 및 영향력을 파악하는 것이다. 이를 위해 부산시를 대상으로 2000년과 2015년의 표준지공시지가를 활용하여 도심 경계를 설정하고 원도심과 신도심의 지가 변화를 비교 분석하였다. 주요 연구 결과는 다음과 같다. 첫째, 최고지가에 대한 비율 8%와 10%를 적용해보았을 때 기존 연구의 도심 경계보다 도심의 범위가 넓게 추정되었다. 최고지가에 대한 비율로 도심의 경계를 설정하는 방법은 시간의 흐름 또는 각 도시의 사회적, 경제적 상황에 따라 달라지므로 신중하게 접근하여야 한다. 둘째, 도심의 지가가 주변지역까지 미치는 파급력은 원도심이 강한 것으로 나타났다. 하지만 최고지가지점(PLVI)이 신도심으로 이전되었을 뿐만 아니라 신도심의 지가가 많이 상승한 점으로 미루어 볼 때 앞으로 부산시의 신도심 지역이 더욱 성장할 것으로 예측된다.

  • The aim of the study is to implement a factor analysis of the determinants of pricing in a state-regulated competitive market using economic and mathematical modelling methods and to develop ways to improve the pricing environment of the market under study. The purpose of the work defines the main objectives: (i) to investigate the features of the competitive model of the Ukrainian flour market; (ii) to analyse the current price conjuncture of the flour market and the dynamics of the main determinants of pricing; (iii)to develop ways of improving the price situation on the flour market on the basis of the factor analysis on the results of economic and mathematical modelling. In order to ensure the reliability and validity of the research results, the following methods were applied: the logical-dialectical method of scientific knowledge in the study of the main theoretical aspects of flour market functioning, the method of logical generalisation and synthesis, comparison, factor analysis, correlation and regression analysis, the graphical method, etc. It has been shown that pricing in a state-regulated competitive market has its own characteristics. For example, in the flour market the price of goods cannot be influenced by producers (sellers) by any methods, therefore determinants of pricing by indirect influence have been taken into account. The five-factor power model of wheat flour price has been constructed. It was substantiated that the price of wheat flour in Ukraine is mostly influenced by consumer price index (0.92 %). The received complex model of wheat flour price may be used also for medium-term forecasting and working out the ways of price formation optimization in the flour market.

  • Purpose - As globalization progresses, complexity also increases, and various factors that threaten port functions are emerging. Accordingly, the demand for port security to prevent the crisis and resilience that quickly recovers its original function after the crisis is also increasing in port operations. However, few studies have examined how to ensure the port security and how the resilience affects operation performance of port and sustainability performance as well. So the study aims to find out how port security affects port resilience and port operational performance, and consequently, this two factors affect socioeconomic and environmental sustainability performance respectively and synthetically. Design/methodology - Confirmatory Factor Analysis (CFA) was first performed to determine the validity of the factors of model and hypothesis test was performed using Structural Equation Model (SEM) to analyze the Port Performance Model, which show the perception logic among port security level, port resilience, operation performance, and sustainability performance. In order to empirically analyze this model, total 264 respondents from port security operators, shipping companies in South Korea were surveyed. Findings - As result of SEM, First, port security level positively affected the resilience (H1) and cargo operational performance (H2) but not in both of the sustainability performances (H3, H4). Second, resilience positively affected only cargo operational performance (H5) and socio-economic sustainability performance (H7). Last, cargo operation performance positively affects the both of sustainability performances (H8, H9). Originality/value - It was confirmed that port security could improve cargo operational performance through ensuring port resilience and eventually increase the socio-economic sustainability. Therefore the study implies that careful integration and management of port security, port resilience, and sustainability are required, along with compromise on sustainable development goals in the social, economic, and environmental area among all stakeholders.
