As the typical farming of the most Asian countries are of small and subsisting scale, the infrastructure is variable depending on the region and more complicated than in the industrialized countries. Except such basic statistics as acreage of farm land, farming population and production, there are no common standard methods to be used for indepth analysis on the farming status, the level of farming techniques, financial status of farming, consciousness of farmers and others. Therefore, it is necessary to develop survey models which can be commonly used to compare with different circumstances. The purpose of this report is to provide examples of survey models which are used to measure farming performances in Korea. Those are (1) Diagnosis and analysis on farming technique, labor utilization and farm income, (2) Management performance analysis, (3) Planning for farming, (4) Survey on the nutritional status of farming, (5) Survey on rural village status and planning regional agricultural development.

With the globalization trend in S&T activities, Korean research organizations have begun to utilize foreign researchers. The performance of foreign researchers is generally regarded satisfactory, but there are many problems too. Moreover, there has not been any research carried out even though there is a growing need for the management of foreign researchers. This paper identified the performance / motivation factors of foreign researchers in Korean research organizations. The statistical results show that the efforts and research capabilities are the most important variables for performance of foreign researchers in Korean research organization. In addition, it is found out that university shows higher performance than government research institute and corporate research organization while it pays the least to the foreign researchers. It is interesting to see that the level of monetary payment is not strongly related with the performance of foreign researchers. In order to utilize the full potential of foreign researchers, it is necessary to enhance the living infrastructure. In addition, due attention should be given to the managerial capabilities of R&D administrators and evaluation/incentive systems of foreign researchers in Korean research organizations.

Importance of FM has rapidly increased because of its growing business. However, due to lack of clarity and identity of FM in professional areas, standardization of FM became to be imperative in such a rapidly changing global business environment. Facility services are defined as the provision of support the primary activities of an organization, delivered by an internal or external provider. Majority of FM activities are services related to 'space and infrastructure' and 'people and organization' (CEN, 2011). The purpose of this study is to investigate definitions and characteristics of FM from both globally and domestic environment, by comparison with international or national standards, to identify quality management in FM and service characteristics of FM, to investigate the differences in service level elaboration in FM, and to suggest standard issues of quality management in FM service quality. This study examines contents of the European Standards in FM, Part 3 'Guidance on quality in Facility Management, especially for the process of QM standardized by CEN (2011) and explores undefined issues such as service level, measurement metrics according to service characteristics of FM. The European FM Standard guides the common process of QM in terms of requirements specification, service level elaboration, measurement metrics development although it does not specifically address various service levels, specific performance metrics and indicators.

The change of the development of transport and logistics systems occurs with the active change of technology and the advent of the era of Industry 4.0. It requires modernization of approaches to the development of transport and logistics systems at the macro and micro levels. The present study aims to identify perspective directions of development and evolution, find out the existing obstacles in the integration of technological solutions of transport and logistics systems at the macro and micro levels. This study is based on a quantitative and qualitative methodology for assessing the level of integration of technologies into transport and logistics systems to study the prospects for their development at the micro level. Macroeconomic indicators of transport and logistics in the context of different regions of the world were used to quantify the development prospects. For a qualitative assessment of the development of the transport and logistics system, the case study method was used. The object of the study was selected logistics company Sensco Logistics Inc., Austin TX. At the macro level, countries with more innovative logistics sectors have stronger mechanisms for coordinating private sector activities. Simplification of administrative procedures of control and regulation by the public sector in order to facilitate trade between countries is a promising direction for the development of transport and logistics systems. Such reforms are more effective in developing a "rigid" transport infrastructure. The integration of Industry 4.0 technology solutions into the international logistics sector is defined by political and legal barriers, especially in developing countries. In low-income countries, hard and soft infrastructure reforms are hindering the development of logistics companies that provide transport services. This determines the national level of development of transport and logistics systems, and in general the global level of development of transport and logistics. In developed countries, the legal barriers to the development of new technological logistics are environmental requirements for the integration of technologies into the transport system. These trends are slowing down the development of International Logistics, which, compared to other industries, is slower to integrate Industry 4.0 technologies. This study combines macroeconomic factors that determine the prospects for the development of transport and logistics systems at the micro level.
