        This research aims to explore the effects of logistics standardization examined by previous studies on customer satisfaction and business logistics performance of enterprises under the rapidly changing logistics environment. To accomplish the purpose, this research conducted the investigation and analysis of effects of logistics standardization on customer satisfaction and business logistics performance of enterprises through previous studies and verified these effects based on the analyzed research materials. In particular, this research conducted the multiple regression analysis of the relation among the degree of components of logistics standardization (e.g. package, transportation, storage, load and unload and logistics information), and customer satisfaction and business logistics performance. The results of empirical analyses by effect are as follows. First, we conducted the multiple regression analysis to verify three research hypotheses. As a result, there appeared significant items of standard pallet and efficiency. According to Hypothesis 1-1, the standard pallet exerted a positive influence of customer satisfaction. Contrary to this, Hypothesis 1-2 showed that efficiency exercises a negative influence on customer satisfaction as it is higher. Further, it can be thought that coherence does not affect customer satisfaction. Second, the multiple regression analysis for verifying three research hypotheses shows that there are two significant items pallet and efficiency. So, the standard pallet and efficiency have a positive effect on business logistics performance. However, efficiency exercise no effect on business logistics performance in that it is not statistically significant. Third, three items material handling equipment for transportation, correlation, and efficiency were not signification according to the multiple regression analysis to verify three research hypotheses. Hence, these three items do not exercise any influence on customers. Fourth, we made the multiple regression analysis to verify three research hypotheses. As a result, one item efficiency showed a significance; hence, it has a positive effect on business logistics performance. However, other two items material handling equipment for transportation and correlation do not influence business logistics performance in that they are not statistically significant. Fifth, we conducted the multiple regression analysis to verify two research hypotheses. This showed one significant item operability. According to Hypothesis 5-2, operability exerts a positive influence on customer satisfaction. Contrary to this, Hypothesis 5-1 tells us that cost has a negative effect on customer satisfaction; hence, it does not affect customer satisfaction. Six, we made the multiple regression analysis to verify two research hypotheses. As a result, we found one significant item operability. Hence, operability exercises a positive influence on business logistics performance. However, cost does not influence business logistics performance in that it is not statistically significant. Seventh, we conducted the multiple regression analysis to verify three research hypotheses. As a result, one significant item material handling equipment was found. According to Hypothesis 7-2, material handling equipment has a positive effect on customer satisfaction. Contrary to this, Hypothesis 7-3 showed that material handling equipment exerts a more negative effect on customer satisfaction as its size is more standardized. So, productivity does not influence customer satisfaction. Eighth, the multiple regression analysis for verifying three research hypotheses shows that there are one significant item material handling equipment. Hence, the standard of material handling equipment exercises a positive influence on business logistics performance. However, material handling equipments and productivity do not influence business logistics performance in that both of them are not statistically significant. Ninth, we made the multiple regression analysis to verify three research hypotheses. This showed one significant item information technology. According to Hypothesis 9-2, information technology exerts a positive influence on customer satisfaction. Contrary to this, Hypothesis 9-3 showed that acceptability exercise a more negative effect on customer satisfaction as it is higher. It can be thought that information literacy do not effect customer satisfaction. Finally, we made the multiple regression analysis to verify three research hypotheses. As a result, we found one significant item acceptability. Hence, acceptability exercises a positive influence on business logistics performance. However, information literacy and technology do not influence business logistics performance in that both of them are not statistically significant. In conclusion, this research has the distinction of the empirical analysis of previous studies on components of logistics standardization (e.g. package, transportation, storage, load and unload and logistics information). In the future, it is needed to make a careful study of identifying factors of outcomes of enterprises (i.e. their business profits) by adding the relevant quantitative factors, in order to contribute to the efficient logistics of enterprises and its improvement. Further, we need to study additional effects relevant to the environment-friendly logistics system in the future, in that internationally increasing are the following two topics made by the developed countries: (1) logistics security and (2) carbon dioxide (CO2) reduction for environmental preservation and management.

        Steel industry has been a driving force of the economic development of Korea which supplies primary materials to the core business of key industries such as the auto industry, the shipbuilders, the electronic appliances makers and the building industry. The United states of America has been one of Korea's main markets which is the biggest steel import country in the world for 30 years. Recently, the biggest export market of Korea has been change from USA to China because of its demand for steel products to soar. But, the general-purpose products are exported to China and the general-purpose and high quality products are steel mainly sold to USA. In this study, the enlargement strategy of export for USA to enhance the international competitiveness of Korea's steel industry is sought. China produced crude steel of 273millions which is explosively increased to 23% of last year's, USA, Japan and EU are solidly increased and East Europe such as Russia(6.7%) and Ukraine(4.9%) is remarkably recovered. The overseas investment of steel industry tends to increase steadily from 13.5% more than domestic investment in 1990s to 40.6% more than it in 2000s. The main obstacle of steel export of Korea for USA is the reinforcing protectionism to protect USA steel industry which has poor competitiveness. The price competitiveness of a integrated steel company is slightly high than other countries' , but it of EAF steelmaking companies is very poor because of high material cost(50% of total cost and big distribution cost of imported scrap(30% of total cost). The market share of general products has been shifted to China as a newly rising steelmaking country. The growth speed of China company such as BoaSteel and Taiyuan Steel which are in the world class companies from the end of 1990s has been fast than domestic steel companies expected. It is imperative that domestic company has the products of quality enough to meet the needs of markets and the production technology to make a high value-added products to export the goods in spite of low-cost China and high quality Japan. Although international steel market will be changed from sellers' market to buyers' market, the domestic steel companies has weak marketing power comparing with other overseas advanced companies. The strategies to cope with domestic and foreign changes are in the government and the companies as followed. First of all, the government makes effort to get rid of the export obstacles for USA with FTA between Korea and USA which is under negotiation and drive a new FTA among Korea, China and Japan. A policy of the development of core minerals can promote and encourage the foreign investment. The barrier of antidumping tariffs can be lowered using multilateral trade grievance machinery such as WTO(World Trade Organization) and DDA(Doha Development Agenda) by the government. The only 1 and world best technology of steel such as strip casting, FINEX, high value added products process and the development of tailored materials which should be obtained by the domestic steel companies is the best solution for excessively steel supply and depression periods. The competitiveness of domestic steel companies will be sharpened by constantly cost down and streamlining of management with the globalized view. In addition, the companies should make ceaseless effort to improve quality of products and delivery with specializing business structure and enhancing core business. The domestic steel industry must transfer to eco-friendly industry to cope with environment regulation such as lowering greenhouse gas. Kyto's climate-change agreements will issue and will also affect on the steel industry which consumes 10.5% of total domestic energy consumption(17.44 million TOE). The domestic steel industry should make desperate effort to minimize pollution by developing a reducing technology of CO2 gas, change to a high efficiency and low consumption energy plant and establish a clean energy using system. Consequently, it is imperative that the relationship not only domestic steel companies and overseas competitive companies but also between domestic steel industry and steel market is strongly intensified to survive under the globalization of steel industry. Therefore, the win-win is that the steel companies supply more stable and more competitive material to domestic steel market and mutual cooperation between big steel companies and small and medium enterprises.

        This study is aimed to contribute on the enhancing of administrative services for citizens in the context of democratization, find problems and make suggestions of enhancing on the behaviors of administrators, relative regime and the structure of the administrative, and the consciousness of the citizens in the sense of the active services for citizens. For these purposes, I studied on the experiences which were obtained by me, civil servant, taking charge of administrative services for citizens for a long time, and the results of the questionaires on the administrative services for citizen between 1984 and 1987. As the existence of administrative services for citizens is to serve for citizen's desire, in the democracy country we think that we cannot empasis its importance too much because administrative services for citizens which are carried out the function of services for citizens. And as the administrative services for citizens is used for the way which establishes the control of citizens and formularize. Its importance is emphasized not only in terms of the services of the citizens but in terms of the administrative development. First of all, in the present time of plunging in democratization and localization, as the local self-government regime is going to be carried in the near future, the expected desires on the administrative of the citizen will be increased as the time has gone, the role and function which administrative services for the citizens will carry out will be occupied more relative importance. But until now in spite of improvement of administrative services for citizens driven in the sense of government, several problems in the sense of the behavior of the administrator, the relative regine an the structure of the administration, the conscious structure of the administrator were exposed. Therefore, the ways to improve these problems and carry out administrative services for the citizens effectly are as follows; 1. The behavior of the administrator should be improved. The administrator should give up the bureaucratic prudential attitude and maintain the kindness, rapidity, impartiality being based on the principle of the equilibrium with the belief of the life of integrity and democratization. 2. The relative law regime and the administrative structure should be improved. The following is needed for the above mentioned. 1) The administrative services for the citizens of centualization should be handed over the organizations of the local self-government and the subordinate angencies. 2) The unification on the window of the administrative services for the citizen and the simplification of the procedure and the attached papers. 3) The new establishment of the education procedure and the status security is necessary. 3. The consciousness of the citizen should be improved. The followings is needed for the aboved mentioned. 1) The strengthing of the publicity on the regine of administrative services for citizens and the establishment of the handling standard on the repeated administrative services for citizen and the false statesments. 2) The introduction of the ombudsman system on many happening field of administrative services for citizen and the application of the consistent law. 3) The establishment of the civil participating regime and the careful attention to the trends of public opinion. 4. Administrative services for citizens should be matured as a science, the police planner should have the right minded consciousness, when all the civil servants serving in the field of administrative services for citizens have a strong innovation, cope with their duties, the real effect of the satisfying administrative service for citizens should be accomplished I think.

        The purpose of this study is to analyze the relationship between political power and the character of the KWO˘NMUN-SEJOK(權門勢族) which is regarded as the dominant political force. The subject chosen was intended to supplement an aspect which has been somewhat neglected and to reconsider certain mistaken views in the study of the subject. These views include a definition of the class as the dominant political force, which makes the classification of classes for the period ambiguous and which is only a partial explanation. They hold that members of the class mostly gained government offices through U˘MSO˘(蔭叔) which means the appointment to an office through the influence of one's family, not through faircompetitions in KWAGO˘(科擧). They assert that the members did not have a good scholarly basis and Confucian learning. There is also the contention that the concentration of power into their hands weakened seriously the power of the crown. Finally, according to the prevalent views, they did not participate actively in the reform movements of the period; they showed a conservative and exclusive inclination. Therefore, they were against the newly arising literati class, the SADAEBU(士大夫), and went down as a class in the process of establishment of a new dynasty, Choso˘n. In connection with these views, the conclusions proposed in this study can be summarized as follows. First, the term, KWO˘NMUN-SEJOK, as used in Koryo˘sa and other sources, should be contidered not as a word but two words, KWO˘NMUN and SEJOK. The common usage of KWO˘NMUN did not point to a particular class but to the extent of power exerted by certain individuals. In comparison, SEJOK indicated family and contained the meaning of a class; it was the ruling class which enjoyed, together with influential family background, power and predominant positions of social and economic importance. Notwithstanding the wide differences between KWO˘NMUN and SEJOK in their characters and their respective sizes, the two separate words were forced into a word, with the result of making errors in restricting the size of the latter and its understanding ambiguous. Furthermore, the prevalent trend in the research of this particular area was to put more emphasis on the KWO˘NMUN than on the SEJOK in considering the ruling class and to result in a confused viewnpiot of holding the latter responsible for the social ills of the period. Secondly, the families in the later period of Koryo˘ that belonged to the SEJOK can be measured according to the number of public officials they supplied. The admittance to the rank of the SEJOK required that a family had produced for three generations or more in succession officials of above 5 P'UM(品), with a higher official like CHECH'U (宰樞) of above 2 P'UM included among them. We can find only 46 families for the period that satisfied these requirements. Of them there are some families which advanced to the nobility in the earlier period of Koryo˘ and maintained their prosperity during the period of military dictators, reaching eventually the rank of the SEJOK after the period of intervention by the Yu¨an dynasty of China; some others rose from the period of military dictators; still others began to provide officials from the period of the intervention and suceeded in establishing themselves as the SEJOK by the end of Koryo˘. Each of the SEJOK went through periods of ups and downs. There were families which rose at the beginning of the intervention period and declined at the end of Koryo˘, and other families which kept rising as time advanced toward the end of Koryo˘. The ups and downs of the families were related to their supply of officials. Temporary exercise of great power worked against their sustaining of prosperity. The SEJOK in the later period of Koryo˘ also was different from the nobility of the earlier period in that it showed more bureaucratic propensity. Thirdly, it has been generally believed that of the two main roads to public offices for the SEJOK, U˘MSO˘ and KWAGO˘, the former was mostly used. Evidences, however, points to the other direction Of 510 persons surveyed 227 persons (45 percents) gained an office through competitions in KWAGO˘. These figures show that KWAGO˘ was the principal, if not the only, way to offices and accordingly given much attention. The primary emphasis on U˘MSO˘ as the channel for officialdom for the SEJOK may have contributed to the mistaken assertion that its members as officers were not well equipped with a firm scholarly basis and wide acquaintance with Confucian teachings. In this connection, it might well be pointed out that a scholarly basis was closely related to economic basis, and that men of tile SEJOK were in a better position to obtain learning. Fourthly, the royal power during the period of the intervention by the Yu¨an dynasty was not really weakened. King Ch'ungyo˘l was a man who experienced the rule of military dictators and witnessed the deposition of his father, Wo˘njong, by Lim Yo˘n. Therefore, the foremost task he imposed upon himself after the collapse of the military rule was the preservation and expansion of royal power. His intention to strengthen royal power was shown in his efforts to form an entourage and a special agency to promote royal power. He bestowed much power upon his cronies to check the influence of royal officials and tried to strengthen the agency to consolidate royal power. There arose a group of P'YEHANG(嬖幸) during the period of the intervention. They were favorites of a king who wielded power granted them by him. They comprised men of various classes, ranging from the SEJOK to the lowest class of society, the CHO˘NMIN(賤民). The power exercised by them was derived not from their offices but from king and was quite influential out of proportion to their offices. Their exertion of power, therefore, was due to king's negligence of control or to his indifference with politics but to his intention to increase royal pwer Thus the shortcut to power for the SEJOK was not the use of family back-ground but the consolidation of its relations with king. TOP'YO˘NGUISASA(都評議使司) has been considered as tile instrument of power for the SEJOK, but it became inefficient by the check of the king's agency during the period of the intervention. This situation makes it clear that the political system of the intervention period was not so effective as to increase royal power, but that it was efficient enough to control the force of the SEJOK by way of king's entourage and agency. Finally, the latter period of Koryo witnessed some reform movements owing to growing maladies plaguing the country. Concerning the efforts at reform, the prevalent assertion was that they were initiated solely by men of humble origins. This assertion, nowever, can be said to come from the lack of thorough investigation into relevant sources. The forces of reform, in reality, included a variety of men from the SEJOK to humble families. The fact that men of the SEJOK participated in the reforms was related to the characters of proposed reforms. The proposals for reform of the later period of Koryo did not consider the maladies of the time as matter of structure and did not intend to rectify them fundamentally. In other word, the reforms were not meant for the interests of the unprevileged classes but to serve certain political purposes. They aimed at only checking the ruling party and redressing more apparent abuses of the time. Because of the limited goals of the reforms that were not directed at the overthrow of the political system itself, even some members of the SEJOK who were equipped with a good scholarly basis and Confucian learning did actively participate in the reforms. It would be most appropriate, therefore, to identify the SEJOK with the dominant class with influential family background in the later period of Koryo˘. Of this class there indeed were men of the KWO˘NMUN who exerted enormous power through their relations with the court of Yu¨an or their king. But these men were only a part of the SEJOK. The SEJOK was the upper class of society, but their influence did not come from the superior position of their class in society and was of ten checked and diminished by the extension of royal power. Of them there were men who attained offices by way of KWAGO˘ and had a good scholarly basis and Confucian learning. These men were not prevented from actively participating in the reform movements because of their status as the member of the ruling class. In this connection, it would be certainly misleading to describe the political and social history of later period of Koryo in terms of contrasting activities of the SEJOK and the SHINHU˘NG-SADAEBU and of the replacing of the one by the other in the establishment of Choso˘n dynasty.
