Real-time monitoring technology is critical for ensuring the safety and reliability of nuclear power plant structures. However, the current seismic monitoring system has limited system identification capabilities such as modal parameter estimation. To obtain global behavior data and dynamic characteristics, multiple sensors must be optimally placed. Although several studies on optimal sensor placement have been conducted, they have primarily focused on civil and mechanical structures. Nuclear power plant structures require robust signals, even at low signal-to-noise ratios, and the robustness of each mode must be assessed separately. This is because the mode contributions of nuclear power plant containment buildings are concentrated in low-order modes. Therefore, this study proposes an optimal sensor placement methodology that can evaluate robustness against noise and the effects of each mode. Indicators, such as auto modal assurance criterion (MAC), cross MAC, and mode shape distribution by node were analyzed, and the suitability of the methodology was verified through numerical analysis.

The Industrial Revolution brought great development to the whole human history by the improvement of productive capacity. However, high speed development absorbed just on growth gave rise to resource depletion attack and economical inequality. If it might be neglected human society will meet unsustainable development situation. So UN has made effort to make sustainable development(SD) through global band together. SD concept considers it important to promote current development not giving damage to next generation's development. Then economy, environment and social integration should be harmonized and it demands governance for its actualization. SD gets to be a matter of common interest in education. New Millenium development Goals make African poor countries that are in blind spots of development advance toward gradual sustainable development by supporting programmes to these countries. Thus sustainable development education(SDE) is for future. It has an aim to give suitable education for all people who are all over the world. SDE tries to make health society and successful economical life for all. The concept of SD is found in the essential aims of Christian school and Christian education seeking justice and shalom. Christians are called as transformers for servant mission giving recover in corrupt world. Firstly, Christian school practise this mission making students think on Christian perspectives. Then it makes students serve for environment, economical fairness, social integration with servant mission. Also Christian school has a mission to seek both justice and shalom as a praxis beyond the intellectual dimension of education until fulfilling justice and shalom for all who are all over the world. Thus it can be that Christian school is an important educational institution for realizing sustainable development in that it is always to seek justice and shalom through restoration on the Christian educational perspective.

Recently, the third mission as the new role of the university is being emphasized as contributing to the local community through active participation in local and regional problems as well as an economic contribution as an entrepreneurial university. Thus, overseas universities started various university-industry collaboration activities targeting sustainable development based on local community and improve their roles for regional regeneration and innovation. Universities in Korea also tend to set up a cooperative governance with various agents in the local community via university financial support projects by the government and started to promote the university-industry collaboration project for solving the problem of the local community. Therefore, this research tries to find implications in order to expand the role and responsibility as local university and reinforce substantiality and enhancement of university-industry collaboration through a case analysis of university-industry collaboration to solve the problem in local communities in foreign countries. In order to solve the problem of local communities based on local agents-led small-sized projects, it is requested to improve the more active role of the university, local governments and university students.

This study was conducted to analyze and compare the dry matter yield of Italian ryegrass (IRG) cultivated under monoculture and mixed culture system to recommend suitable varieties that can be cultivated. Italian ryegrass cultivars, Green Fram (GF, extremely early-maturing), Kowinearly (KE, early-maturing), Kowinmaster (KM, mild-maturing), and Hwasan 104 (H104, late-maturing), were used for mono or mixed cultivation. The average monthly temperature in Cheonan over the past 30 years tended to be similar, but that in November and March are judged to be abnormal weather. The dry matter yield of GF+H104 was significantly higher during harvest than that of GF (p<0.05). The dry matter yields of KE and KE+KM were significantly higher during harvest than the output standards of KE and KM. There was no significant difference between the dry matter yield of H104 and KM (p>0.05), but KM had the highest yield of 16,763.1 kg/ha. Analysis showed that the highest dry matter yield during IRG harvest was obtained under monoculture and KE+KM mixed culture. Because the occurrence frequency of abnormal weather such as drought during spring is increasing recently, it is judged that IRG cultivation using early and middle growth is necessary to prepare for abnormal weather.

With the advent of the era of the 4th industrial revolution, various factors such as economy, management, and culture are changing in modern society, unlike in the past. Among them, the main characteristic of management is the change from intangible goods to tangible goods, and companies are trying to pursue innovation such as introducing a new management method, converting from manufacturing to service, and expanding technology. However, with regard to human resources, which is becoming the most important for sustainable value creation in a changing era, efforts to enable practical innovation are lacking as they are still in a simple transition. Therefore, in this study, after recognizing the importance of human resources, we verified the relationship between the elements of the human resource in the service economy era according to organizational culture and organizational structure. The relationship between organizational culture and organizational structure by type was verified using the items of human resources, we verified the relationship between the elements of the human resource in the service economy era that were derived and verified in recent research. As a result, there were some significant differences in the image of human resources, we verified the relationship between the elements of the human resource by organizational culture and type of organization, but when the two factors were combined and interpreted, it was found that all of the human resources, we verified the relationship between the elements of the human resource in the service economy era were necessary. However, in order to overcome the limitation that the indicators of this study were limited, it is necessary to continue research through samples that consider various factors in the future and systematic classification by type of organization and industry by industry.

In Korea, which is entering a super-aged society, the number of elderly patients who have difficulty walking independently is expected to increase rapidly, and it is necessary to develop wheelchair products with various functions to improve the quality of life of people with walking disabilities. Recently, wheelchair power assist devices that provide propulsion power by being attached to a manual wheelchair has been developed and is entering the domestic and global markets. In this study, we compared and analyzed the process of obtaining medical device certification for wheelchair power assist devices in Korea, the United States, and Europe. In Korea, a Class 2 medical device certification process was developed in 2021, and in the US FDA, it corresponds to Class 2 like the existing electric wheelchair and must pass the 510k certification process. In the case of Europe, it is uniquely regulated as Class I, and the CE mark can be attached through a relatively easy self-declaration of conformity. The Korean medical device industry, which is struggling with MDR certification, a new European medical device regulation, should pay attention to the relatively easy entry into the global market for wheelchair power assist products.
