The purpose of this study is to verify the mediating effect of pay satisfaction on the relation between procedural justice and organizational commitment. A survey was conducted to examine the mediating effect of pay satisfaction on the responses of 529 employees. The study chose sex, age, education, position, job type and career as control variable, and the regression model which treated procedural justice as independent variable and organizational commitment as criterion variables were set. A pay satisfaction was supposed as mediating variable of these relationships. The data analysis was conducted by SAS 9.4ver and LISREL 8.80. The results of this study confirm underneath the followings. First, the relation of procedural justice and organizational commitment are significantly unique. Second, procedural justice are positively related to pay satisfaction. Third, pay satisfaction is significantly positively related to organizational commitment. Fourth, the pay satisfaction is partially mediated on the relationship between procedural justice and organizational commitment. This means that the pay satisfaction mediates the relation of procedural justice and organizational commitment. These results are different from the prior researches which had treated pay satisfaction as mediating variable of procedural justice and organizational commitment. Based on the findings of the study, this study presented managerial implications and suggestions for future studies.

The purpose of this study is to verify not only the impact of servant leadership affecting creativity but the mediating effect of empowerment. Creativity refers to the production of novel and useful ideas by an individual or by a group of individuals working together [2]. A survey was conducted by 301 employees. This study used the structure equation model which treated the servant leadership as independent variable and creativity as criterion variables. Empowerment was supposed as mediating variable of these relationships. As a result of this study, servant leadership had positive influence on empowerment. Empowerment had positive influence on creativity. Also servant leadership had positive effect on creativity at first, but it did not have a direct effect on creativity when empowerment was considered. These mean that empowerment is complete mediation variable because servant leadership no longer affects creativity after empowerment has been considered. Several implications, limitations and directions for future research were discussed.

In recent several studies, interactional justice as well as distributional justice and procedural justice was founded as a important factor of justice. But the other studies proposed that interactional justice was a sub-dimension of procedural justice bec

알루미늄은 낮은 비중을 가지는 금속으로 철에 비하여 상대적으로 가볍고 비강도가 크므로 건축물의 외장 재료로 많이 사용되고 있다. 알루미늄의 경우 다른 금속에 비해 산화되기 어렵고 낮은 융점으로 인해 사용이 끝난 알루미늄 재료의 경우 녹여서 재활용이 가능하다. 건축물 외장 재료로 사용되는 복합 패널의 경우 철, 동, 강 등의 금속과 알루미늄이 결합된 구조로 되어 있고 알루미늄을 분리할 경우 쉽게 재활용이 가능한 장점을 가지고 있다. 이러한 복합 패널에서 사용되고 있는 알루미늄을 재활용하기 위해서는 결합된 소재들을 분리하는 단계가 필요하다. 알루미늄 복합 패널은 건축물 철거 시 발생하는 폐자재로 일정한 형태가 없고 크기가 다르므로 일반적인 재활용 장비에서 처리하기에는 어려운 상황이다. 일반적으로 대부분의 재활용 업체에서는 가열하거나 수작업을 통해 알루미늄을 분리하고 있지만 가열방식에서는 유해가스 배출로 인한 환경 문제와 수작업을 통한 높은 인건비 비용에 대한 문제점이 나타나고 있다. 따라서 본 연구에서는 다양한 형태의 복합 패널 폐자재(스크랩)를 효율적으로 재활용할 수 있는 설비 및 방법을 개발하는 것을 목적으로 한다. 개발된 장비를 통해 복합 패널을 일정한 크기로 분쇄하고 파쇄된 복합물에서 알루미늄과 폴리에틸렌을 분리하여 최종적으로 분리된 알루미늄을 일정한 크기의 그래뉼 입자로 만들었다. 구조해석을 통해 장비의 안전성을 검증하고 일정한 크기 및 순도를 가진 알루미늄 그래뉼 입자가 생성되는지를 확인하였다. 최종적으로 생산된 알루미늄 그래뉼 입자의 순도 및 크기를 분석하여 건축용 복합 패널 스크랩의 알루미늄 재활용성에 대한 평가를 분석하였다.

This study investigated the quality characteristics between spring cultivars of Kimchi cabbage(Brassica rapa L. ssp. pekinesis). We measured the weight, length, width, formation index, midrib thickness and moisture contents of fresh Kimchi cabbage for characteristics of growth. And we analyzed the free sugar, amino acid, organic acid, mineral, pectin and cellulose contents of fresh Kimchi cabbage. The hardness and firmness were measured for texture of fresh Kimchi cabbage. The weight of 'K-power' cultivar was the highest than other cultivars. The ‘Jeongsang’ cultivars was the thinnest midrib thickness in cultivars, but it was not significantly different. The free sugar levels of spring cultivars was the highest in ‘Chunkwang’. Malic acid content of ‘Jeongsang’ was significantly different among spring cultivars. Also amino acid content of ‘K-power’ and ‘Chunkwang’ were significantly different among spring cultivars Mineral content in ‘K-power’ and ‘Bomaknorang’ were greater than that of other cultivars. Especially Na, Ca and Mg contents of ‘K-power’ and ‘Bomaknorang’ were higher four times than that of other cultivars. Pectin content of ‘Jeongsang’ was higher than that of other cultivars, but it was not significantly different. Hardness and Firmness were not significantly different among spring cultivars.

The amount of the Korean export & import in 1987 reached 88.3 billion which was 1.75% of the total world trade and the proportion of foreign dependence to G.N.P was 74.5%. From these facts, we can infer that the development of national economy is largely dependent upon trade. Therefore the role of transportation, especially Ocean transportation, as a basis of economic development through trade is one of the main factors that can not be passed over. Here, We can define that a port as a subsystem of transportation determines the efficiency of the total transportation system. Thus, the purpose of this paper is to contribute in improvement of the efficiency in port, reinforcement of the international competitiveness for exporting goods by the analysis of the cargo handling charges. In order to do this, this paper deals the case of B.C.T.O.C. Furthermore, this study gives some important informations related to the level of tariffs for establishing an autonomous port administration. The Summary of the conclusions of this paper is as follows ; 1) The object of port administration in Korea has been emphasized on the maximization of efficiency in using the port facilities. Nowadays, however, it should be moved to a direction that port is operated under the compound aims considering the public interests and economy. 2) For a criterian of tariff calculation, A tariff system based on the cost accounting is desirable. In general it is recommended that the cost for construction, management, and operation of port is compensated by the revenue from port operation. Therefore, it is necessary for the administration bodies of each port to establish a tariff system on the basis of the independent profit system. 3) For the investigation of actors of tariff adjustment by the Break-even point analysis, (1) When we conducted the B.E.P analysis using total cost as cost term, we got 3.8% discount in tariff at 12% of target profit rate and 1.5% discount at 15% of rate. when we set the target profit rate as 17% we could have the proper tariff level. (2) When using operating cost as cost term, we got 13.1% discount in tariff at 12% of target profit rate and 10.9% discount at 15% of rate. When setting the target profit rat as 28%, we could have the proper tariff level. 4) Comparing with the tariffs of foreign ports for the basic terminal rate, The tariff level of B.C.T.O.C showed 33% of stevedoring charge and 80% of marshalling charge incurred at Kobe port. The comparison with Singapore port gave 50% of transhipment charge and 17% - 20 % of stevedoring charge. 5) We found that the financial structure of B.C.T.O.C was better than those of other companies and the worth fixed assets ratio was too low. The fact of low worth fixed assets ratio implies that the cargo handling facilities should be increased. Moreover, The return of assets for B.T.T.O.C was good but non-operating expenses were still contained too much in. Therefore, we think that it is necessary for B.C.T.O.C. to rationalize business management. Although the present cargo handing charge for B.C.T.O.C is a proper level in terms of a public corporation, for the final recommendation in connection to the results, It is required to take the rationalization process for business management.
