This paper attempts to explain the effect and application of action research in Korean social welfare research and discusses utilities of action research in the broadening and deepening social welfare body of knowledge within Korea. First, this paper examines the concepts, characteristics, and relevant literatures of action research. Second, this paper attempts to explain the effect, meanings, and application of action research in Korean social welfare research with examples from study on development of user involvement manuals for the disabled residential facilities for the first time in Korea. Third, this paper discusses utilities of action research in broadening and deepening social welfare knowledge body in Korea. In discussing the utilities, this paper maintains that action research can be more properly utilized for research methods to decrease the gab of research and social work practice. Finally, this paper highlights that 'many ways of knowing' exist in social science and it should be considered more sincerely in the arena of Korean social welfare research in order to more solidly develop the knowledge body of social welfare and practice in Korea.

Korea and China are neighboring countries with close contacts in many areas from long time ago, and have shared interests in maintaining peace and stability on the Korean Peninsula, and in deepening economic relationship which has been mutually complementary in their nature. Therefore their bilateral relations has been developed at a remarkable pace to the extent that it can't be better than now. However, the differences in their responses to North Korean nuclear test and ensuing long-range ballistic missile test-fire and the Chinese strong concern on the possible deployment of THAAD (Terminal High Altitude Air Defence) anti-missile system in Korea show that there are some weaknesses in their relations. For example, Korea is not still confident that China would fully implement the sanction measures contained in the UNSC resolution and I argue that Chinese proposal of parallel negotiation of the denuclearization and the replacement of Korean armistice with the Peace Agreement is not much persuasive. In THAAD issue, if Korea comes to conclusion in the future that THAAD is the most effective way to counter North Korean threats, Korea should make every efforts to assure China that Korea-US alliance is not targeting China, and the THAAD is a defensive system, not damaging Chinese security. In the longer-term, deepening strategic distrust and competition between the US and China in this part of East Asia, changing nature of economic cooperation between Korea and China, and the revival of 'great country mentality' by Chinese people together with the rising nationalism in both Korea and China would cast shadow on Korea-China relation in the years ahead, unless properly handled. In this regard, I suggest that the security communications between the two countries be further strengthened, and the tri-lateral dialogue channel be established among the three countries of Korea, the US and China, particularly on North Korean issues. I also suggest the new pattern of economic cooperation be sought, considering the changing economic environment in China, while strengthening the efforts to understand each other through more interactions between the two peoples.

The synchondrosis between the sixth and seventh costal cartilage is usually used for the base frame in autogenous ear reconstruction. If the synchondrosis is loose, a variety of modifications can be devised. This report introduces new methods for these problems. In cases of incomplete synchondrosis, only the surface of the base block margin was smoothly tapered without carving for the removal of the conchal deepening. The secure fixation of the two segments (helix and antihelix) to the base block using fine wire sutures gave stability to the unstable basal frame. After confirming that all the segments were assembled in one stable piece, the remaining conchal deepening of the basal framework was removed, and the outer lower portion of the basal cartilage was trimmed along its whole length. A total of 10 consecutive patients with microtia, ranging from 8 to 13 years old, were treated from 2008 to 2009. The follow-up period was 6 months to 2 years. Despite incomplete synchondrosis, the stable frameworks were constructed using the authors' method and aesthetically acceptable results were achieved. The proposed method can provide an easy way to make a stable cartilage framework regardless of the variable conditions of synchondrosis.

As technological capabilities have enhanced, the patterns of innovation activities of latecomer firms changed to post catch-up mode. The purpose of this research is to analyze the post catch-up innovation patterns of technology-intensive small and medium firms of Korea. The innovation patterns can be divided into three types: the technology deepening innovation type, the new technology based innovation type and the architectural innovation type. The characteristics of the technology deepening innovation type are cumulative technological learning and the integration of new generic technology and existing technologies. The characteristics of new technology based type are the acquisition and revelations of new basic knowledges from former incubating organizations such as large firms and universities. The characteristics of the architectural innovation type are the learning of system architecture knowledge from former organization and interactive learning with user firms. These post catch up innovations also have some general characteristics. They effectively exploited the windows of opportunities which are opened in the middle of technological paradigm change.

This study investigated into the effects of the colors of warp and weft on the overall colors of fabrics, along with the visual changes of colors by the measuring angle of both warp and weft, by means of cross-dyeing of cotton/PET union fabrics. First, the reflectance of polyester is higher than that of cotton over the whole wavelength. Second, the dyeing of polyester uses the disperse dyes and that of cotton uses fiber-reactive dyes, the differences in the features of dyes and the reflectance of fabrics cause the same colors to be perceived different by the angle of observation. Third, the dyeing of cotton and PET fabrics individually with the same color revealed that the dyeing of cotton and PET fabrics in one bath resulted in a small difference in colors between the two fabrics than the separate dyeing in two bathes. In the case of one bath, the dyeing of PET fabrics followed by that of cotton fabrics resulted in a small difference in color than the dyeing in the reversed order. Fourth, when cotton/PET union fabrics were dyed in ten colors, the difference in colors between the two fabrics was small; and due to the difference in the density of warp and weft of union fabrics, some difference was detected in comparison with the results of separate dyeing of cotton and PET fabrics in one bath. The latter did not produce the changes in color which was recognizable with the naked eyes. Fifth, when cotton/PET union fabrics were dyed in ten colors, any color change was not observed by the measuring angle, and the inclination in the direction of warp or weft resulted in the tendency of color-deepening. In the measurement of the latter, the inclination in the direction of weft resulted in the higher color-deepening than that in the direction of warp, due to the influence of weft.

Due to COVID-19, people are building new lifestyles such as online shopping, online travel, and video conferencing by limiting going out and gatherings. Such rapid social change is causing new problems and deepening existing problems at the same time. In particular, as online consumption increases significantly, traffic congestion, air pollution, and the heavy workload of delivery drivers are deepening in the daily logistics industry, and face-to-face delivery is emerging as a new problem. With the advent of the 4th industrial revolution, unmanned delivery using drones, artificial intelligence, and autonomous driving is emerging as an alternative to the existing logistics industry. However, space for logistics facilities and securing additional logistics sites due to drone flight are emerging as new problems to be solved. Therefore, it is intended to link additional services such as logistics movement, storage, and delivery by utilizing the existing transportation business, the subway, as a space for a logistics facility for drones that can solve existing problems and new problems.
