  • The objective of this paper is to think about what structural reforms of the Korean government S&T development management system might be. Korean society is currently experiencing a drastic socio-economic transformation. The results of this transformation should be reflected on the determining process of the directions and breadths of structural reforms of government S&T development management system. Because the government system design will be based on the premises of socio-economic conditions under which administrative activities perform and also this socio-economic changes can influence on changes of the premises of government management system design. Moreover, S&T development management system is a subsystem of government system so that the directions of structural reform of those subsystems should be considered in the broad framework changes in the development management system of the government. For the last forty years, the Korean government S&T development management system has been based on the premises including transformation from an agrarian society to an industrial society, authoritarianism and centrally controlled institutions, and exteremely small portions of private investments for science and thechonology R & D of the total. Recently, however, the premises of Korean government S&T development management system have rapidly changed. the characteristics of these changes are including tranformation from an industrial society to a knowledge and information intensive society, globalization, localization, and relatively large portion of private investments for science and technology R & C of the total. The basis of government reforms in Korea was the realization of the performances and values through the enhancement of national competitive capacity, attainment of lean government, decentralization and autonomy. However, the Korean government has attached a symbolic value of strategic organizations representing strong policy intentions of government for the science and technology based development. Most problems associated with the Korean government S&T development management system have grown worse during 1990s. Many people perceive that considerable part of this problem was generated because the government could not properly adapt itself to new administrative environment and the paradigm shift in its role. First of all, the Korean government S&T development management system as a whole failed to develop an integrated vision under which processes in formulating science and thechology development goals and developing consistent government plans concerning science and technology development are guided. Second, most of the local governments have little organizational capacity and manpowers to handle localized activities to promote science and technology in their regions. Third, the measure to coordinate and set priorities to invest resources for the development of science and technology was not effective. Fourth, the Most has been losing its reputation as the symbol of ideological commitment of the top policy maker to promote science and technology. Various ideas to reform government S&T development management system have been suggested recently. Most frequently cited ideas are as follow : (ⅰ)strengthen the functions of MoST by supplementing the strong incentive and regulatory measures; (ⅱ)create a new Ministry of Education, Science & Technology and Research by merging the Ministry of Education and the MoST; (ⅲ)create a new Ministry of Science & Technology and Industry ; and(ⅳ)create a National Science and Technology Policy Council under the chairmanship of the President. Four alternatives suggested have been widely discussed among the interested parties and they each have merits as well as weaknesses. The first alternative could be seen as an alternative which cannot resolve current conflicts among various ministries concerning priority setting and resource allocation. However, this alternatives can be seen as a way of showing the top policymaker's strong intention to emphasize science and technology based development. Second alternative is giving a strategic to emphasize on the training and supplying qualified manpower to meet knowledge and information intensive future society. This alternative is considered to be consistent with the new administrative paradigm emphasizing lean government and decentralization. However, opponents are worrying about the linkages and cooperative research between university and industry could be weakening. The third alternative has been adopted mostly in nations which have strong basic science research but weak industrial innovation traditions. Main weakness of this alternative for Korea is that Korean science and technology development system has no strong basic science and technology research traditions. The fourth alternative is consistent with new administrative paradigms and government reform bases. However, opponents to this alternative are worried that the intensive development of science and technology because of Korea's low potential research capabilities in science and technology development. Considerning the present Korean socio-economic situation which demands highly qualified human resources and development strategies which emphasizes the accumulations of knowledge-based stocks, I would like to suggest the route of creating a new Ministry of Education, Science & Technology and Research by intergrating education administration functions and science & technology development function into one ministry.

  • This study examines the technical level of North Korea's S&T and identifies areas for potential North-South cooperation. First, North Korean media is analyzed for situations and trends from 2010 to 2015. Despite some commendable achievements, North Korean S&T remains lacking in basic science and commercialization potential. Despite an awareness of the importance of international cooperation, North Korea is hampered by international sanctions and their own caution, consequently concentrating their efforts on China. Details of their cooperation reflect their interests and needs to a certain extent, although their collaborations were mainly in the form of meetings and conferences rather than active joint research. To assess the potential areas of cooperation with South Korea, this study also draws on interviews with NGOs and professionals working with North Korea. The country's present situation is analyzed and some practical examples of possible cooperation is suggested. North Korea has the potential to expand its cooperation not only with South Korea but with many other countries. North Korea also promisingly expresses interest in cooperation.

  • DDoS(Distributed Denial of Service) 공격은 네트워크상에서 다수의 시스템 협업으로 하나의 표적 시스템을 공격하여 서비스의 가용성을 침해하는 공격이다. 이는 점차 지능적인 방법으로 진화하고 있으며 특히 IoT를 대상으로 한 DDoS 공격이 증가하고 있다. 이기종의 기기들이 연결된 IoT는 기존 IT디바이스와 비교하여 제한된 자원을 가지고 있어 IoT 네트워크 특성을 고려한 DDoS 보안 기법이 요구된다. 국제 인터넷 표준화 기구 IETF에서 IoT를 지원하기 위해 제정한 CoAP(Constrained Application Protocol)은 기존 IT 네트워크와 호환성을 가진 응용 계층 프로토콜이다. 본 논문은 CoAP의 DDoS 공격 취약점과 대응 방안을 정리하고 새로운 프로토콜을 추가할 시 고려해야 할 사항을 제시한다.

  • This experiment was carried out to investigate the effect of rumen-protected lysine (RPLys) on growth rate, feed efficiency and plasma amino acid concentrations in sheep. RPLys was supplemented at the level of 0% ($T_1$), 0.2% ($T_2$) and 0.4% ($T_3$) of total DMI with 24 sheep in a 56 day feeding trial. The results are summarized as follows: 1. live weight gain of sheep in groups $T_1$, $T_2$ and $T_3$ was 219, 216 and 244 g/d, and was significantly (p < 0.05) higher for $T_3$ through the entire experiment. 2. Feed intake was not affected by RPLys supplementation. 3. The group fed $T_3$ had a significantly (p < 0.05) better feed efficiency than the groups fed $T_1$ and $T_3$. The response of $T_3$ was higher in growing period II of feeding low protein basal diet than in period I. 4. Plasma lysine concentrations tended to be higher with supplementing RPLys, but there were no differences between $T_2$ and $T_3$. 5. Supplementing RPLys in the diets increased plasma concentrations of arginine, asparagines, threonine, serine, valine and leucine compared with sheep receiving no RPLys. In contrast, plasma histidine was lower in sheep fed the supplementing RPLys than fed the diet $T_1$ with significant (p < 0.05) difference.

  • This research explores a framework of selecting suitable industry cooperation ares between South Korea and North Korea using analysis of science and technology(S&T) competitiveness. First, a generic framework to set up S&T cooperation with North Korea, which involves both a continuity as an evolving process and a peculiarity of S&T, is presented. Second, a selection procedure of specific S&T areas for South and North cooperation is suggested. It is also demonstrated how to select suitable S&T cooperation areas under two types of scenarios. Finally, promotion strategies for each scenario are described.

  • This experiment was conducted to investigate the protein sparing effect of rumen protected lysine(RPLys) and methionine hydroxyl analogue(MHA) in sheep. The treatments were $T_1$ (CP 15% + RPLys 0%), $T_2$ (CP 12% + RPLys 0%), $T_3$ (CP 12% + RPLys 0.4%) and $T_4$ (CP 12% + RPLys 0.4% + MHA 0.3%). Ruminal characteristics, in situ and in vitro digestibility and nitrogen retention rate were measured in sheep receiving different combinations of dietary supplement. The results are summarized as follows: 1. Ruminal pH and VFA concentrations were not affected by the treatments. Ruminal ammonia-N concentration was high in sheep fed diets $T_2$, $T_3$ and $T_4$ with the highest value in the $T_4$ treatment(p<0.05). 2. The digestibilities of dry matter and organic matter were not affected by the treatments. 3. Nitrogen losses through feces and urine were the highest with $T_1$ (p<0.05) and nitrogen retention rates of groups $T_1$, $T_2$, $T_3$ and $T_4$ were 18.6, 32.4, 35.5 and 27.5% of nitrogen intake, respectively, indicating that RPLys supplementation improved nitrogen retention in sheep.

  • Korea has accomplished remarkable economic growth based on the accumulating technological capability. Science and Technology policy aiming at quantitative growth has concentrated on S&T hardware infra-structure construction but it overemphasizes technological factors. This policy has not sufficiently reflected social and cultural elements that should be incorporated in S&T development process. Therefore many experts have been emphasizing the importance of science culture as an important ingredient of S&T policy. This paper aims at investigating how science culture could be diffused. Nowadays, many countries have a strong interest in science shop as an important instrument of science culture. Science shop, however, has been activated in European area so it is not familar to Korea. However there are already a few science shops in Korea. In this paper, we will investigate the Korea science shops. In particular, we will analyze the current status, organizational structure and problems of Korea science shops. we will draw some important policy implications to activate science shops and to strengthen S&T policies in Korea.
