The purpose of this research is to develop strategic alternatives for the high-tech products development by comparatively studying characteristics of the industry and R&D structures in Korea and the US. Some of the environmental, strategic, organizational and project teams' characteristics are studied. Data were collected from Korea and US high-tech companies through interviews and questionnaires and event analysis method was used to analyze them. The findings are as follows: First, when the level of market concentration is high, cycle time tends to be longer. Therefore, if there are many competitors in the market, new products development should be swift due to competitive pressures. Second, the developmental strategy should be directed toward the existing customers to speed up new products development. That is, a defensive strategy would result in a shorter cycle time and response time compared to a strategy directed to a niche market. Third, when the level of formalization is high, cycle time tends to be shorter. This means that formal procedures for new products idea development or new products development policies shorten new products development time.

In analyzing the effect of the central place improvement projects, this study classifies subject residents into two groups of the residents of the project target regions and those of surrounding villages, and conducts verification. As a result of analysis, Variety of cultural programs is the only factor that positively affects the satisfaction level of the residents of the project target region, and it has been analyzed at the significance level of 10% that a one-unit increase in securing rest areas lowers the satisfaction level of the residents of surrounding villages. This shows that the effect of the central place improvement projects currently promoted is at a low level, and there is also a risk of conflict between the residents in the target region and those in surrounding villages. Although there is no statistical significance, analysis shows that a method to provide the residents in surrounding villages with the project-related information and to guarantee their participation in the project enhances the satisfaction level of the residents of surrounding villages. Therefore, institutional improvements reflecting this need to be made.

This study developed a settlement environment diagnostic indices (SEDI) of rural villages which can apply to analyze variable conditions of villages having development projects. The index consists of 5 diagnostic areas (first level) with 13 items (second level), including detail indices of 40 criteria (third level) defined by specialists' brainstorming process. In order to develop the index system, object-oriented approach was used to extract the 5 diagnostic areas (infra-basic settlement facility, life condition & environmental resources, industry & economic infrastructure, community, and residents) from rural villages. For the 40 criteria, it was introduced a quantification method that all villages have absolute values in national level, not relative value between villages within an unit area. The diagnostic diagram and table were developed to evaluate the villages compositively. The developed SEDI was applied to study areas, 56 villages in 2 subdivision areas of county, located on county of Keumsan. Applicability of the index system, database system should be developed with the surveying method of data in village level.

Since automated driving system (ADS) has great potential to innovate various fields of automobile and mobility industries, major countries are establishing safety standards for autonomous vehicles to support technology development. However, in order to prevent technology development from being hampered by the safety standards for technologies still under development, safety guidelines are applied until the technologies are mature. For example, the safety 'guideline' for level 4 ADS was published in December 2020 by the Ministry of Land, Infrastructure and Transport of Korea, while the safety 'standards' for level 3 ADS was promulgated in December 2019. In this study, the domestic safety guideline for level 4 ADS is analyzed with the guidelines of major advanced countries in terms of safety elements. As it takes a lot of time before the safety standards of level 4 ADS is introduced, it is expected that the safety guideline will be updated several times. As necessary considerations when updating the safety guideline, industry acceptance, harmonization between safety elements, validation methods of system performance, and the user options are discussed.

The introduction of digital technologies affects most socio-economic processes and activities in the economy, from agriculture to public services. Even though the world is currently only in the early stages of digital transformation, the digital economy is growing rapidly, especially in developing countries. Shortly, digital platforms will be able to replace the "invisible hand" of the market and turn it into digital. Some digital platforms have already reached global reach in some sectors of the economy. The growing value of data and artificial intelligence is reflected in the high capitalization of these enterprises. Their growing role has far-reaching consequences for the organization of economic activity and integration into the field of e-business. However, their importance and level of development in different countries differ significantly. The main purpose of this article is an assessment of the level and trends of the digital economy in the world and the identification of homogeneous groups of states following the main trends in the development of its components from among the EU countries. The methodology of the conducted research is based on the use of general scientific research methods in the analysis of secondary sources and the application of statistical methods of correlation-regression and cluster analysis. Macroeconomic indicators and components of DESI (Digital Economy and Society Index) were used for the analysis. Results. Based on the analysis established that most developed countries have a medium level of digitalization of the business environment and a high level of digitalization of socially oriented public services, while countries with lower GDP focus their policies on building digital infrastructure and training qualified personnel. The study summarizes and analyzes current trends in digital technology, analyzes the level and dynamics of integration of digital technologies of the studied EU countries, the level of development of e-business and e-commerce. The conceptualization of mechanisms of creation of added value in the digital economy is offered and the possible consequences of digitalization of the economy of developing countries are generalized.

In order to understand the underwater noise source factor of the linear pump type forced ejection system, a reduced-model compressed water experiment device was developed. The reduced-model compressed water experiment device consists of a reverberation tank, a linear pump type forced ejection device, and an underwater vehicle. The underwater noise source was selected from the hydraulic ram moving speed, the hydraulic ram/piston pipe spacing, the ejection pipe inlet/water ram area ratio, and the number of water ram inlets. The underwater vehicle was ejected into the reverberation tank by the device. The source level was derived from the measured sound pressure. The source level tends to increase as the hydraulic ram/piston tube spacing and the hydraulic ram moving speed increase. The source level tended to increase as the area ratio was increased, but the level was weak. The number of water ram inlet did not affect the source level.

Although the philosophy of sustainable community development does not give the cure-all solutions for the major problems faced in the communities, it is theoretically and practically recognized as a newly emerging paradigm toward community development theoretically and practically. However, more specific tasks and issues of sustainable community development remain unchallenged and descriptive statements. The main objective of this study was to find out the extensive community development practices through the review of current works in the area of sustainable community development indicator, local agenda 21 and the relative issues. The recommendations of this study were the following; 1) The sustainable community development indicators available in the community level should be selected. Also, how to integrate the objective condition and subjective perception in community development practices, and how to weigh the indicator item should be solved in order to compare and measure the implementation of community development works. 2) In relation to local agenda 21, how to secure the implementation mechanism is more important than the developing the local agenda 21. 3) The policies aimed to raise the resident's awareness, formation of community field, create community social capitals, and define strategies to the selective community development programs should be considered to make the philosophy of sustainable community development active in the field level.

In applying modeling and simulation (M&S) techniques to analyze complex discrete event dynamic systems, conventionally users had to use different simulation environments depending on the user-level. To solve the inconvenience, this paper proposes an integrated development environment for M&S depending on user-level and a formalized interface to manage the model in the development environment efficiently. The interface consists of an extended DEVS formalism and model making rules. The development environment is divided into a modeling environment and a simulation environment. In the modeling environment, three modeling methods are provided for each level of the users. Users inputs several parameters to the model generated as a result of the modeling process, and experiments in various cases by using the simulation environment. The case study shows the implementation of the proposed M&S environment, and using the implemented environment, it shows the M&S process of the complex defense combat system.
