Timber inventory management includes to measure and update forest attributes, which is crucial information for private companies and public organizations in property assessment and environment monitoring. Field measurement would be accurate, but time-consuming and inefficient. For the reason, remote sensing technology has been an alternative to field measurement from an economic perspective. Among several sensors, LiDAR and Radar interferometry are known for their efficiency for forest monitoring because they are less influenced by weather and light conditions, and provide reasonably accurate vertical/horizontal measurement for a large area in a short period. For example, Shuttle Radar Topography Mission (SRTM) and National Elevation Dataset (NED) in the U.S. can provide tree height information and DSM. On the other hand, LiDAR DSM (the first return) and DEM (the last return) can also present tree height estimation. With respect to project site of loblolly pine plantation in Louisiana in the U.S., the accuracy of SRTM C-Band approach estimating tree height was assessed by the LiDAR approaches. In addition, SRTM X-Band and NED were also compared with the results. Plantation year in inventory GIS, which is directly related to forest age, is high correlated with the difference between SRTM C-Band and NED. As a byproduct, several stands of age mismatch could be recognized using an outlier detection algorithm, and optical satellite image (ETM+) were used to verify the mismatch. The findings of this study were (1) the confirmation of usefulness of the SRTM DSM for forest monitoring and (2) Multi-sensors- Radar, LiDAR, ETM+, MODIS can be used for accuracy improvement of forest inventory GIS altogether.
Science and technology diplomacy has become an important policy agenda because of its diplomatic utility and enhancing of international science networks. However, different countries possess different objectives and governance of S&T diplomacy. In this context, this paper seeks to answer the following questions: what are the similarities and differences of S&T diplomacy in countries and what shapes these characteristics? To answer these questions, this paper conducts a comparative case study with five countries - Switzerland, Germany, Japan, the United Kingdom, and the United States - whose S&T diplomatic programs are highly recognized and benchmarked by other countries. A useful typology is devised to conduct a systematic comparison. For S&T diplomatic objectives, this paper suggests five types by elaborating concepts from the previous literature: access diplomacy, promotion diplomacy, public aid diplomacy, functional diplomacy, and global leadership diplomacy. Also, in terms of a governance model for S&T diplomacy, three models - a sciencecentered model, a science-outsourcing model and a top-down coordinating model - are suggested based on leadership organization. This paper reveals the different characteristics of the selected countries in S&T diplomacy. While the selected countries pursue almost every type of S&T diplomatic objective, the US and the UK tend to conduct influence-based diplomacy more than other countries do. In addition, different countries each have unique governance models for S&T diplomacy. While more research is necessary for vigorously testing the causes of different objectives and their relationship with governance models, this paper suggests more general policy implications throughout. The strength of the country's S&T base is fundamentally important for the success of S&T diplomacy. However, domestic S&T assets need to be transferred to its diplomatic capabilities. In this sense, the appropriate governance that fits best with the country's S&T mission should be established, while S&T communities should increasingly play a leadership role in evolving global S&T networks.
Constitutional issue of economic order has fiercely been disputed around the world and through the ages. In Korea, there also has been endless argument on to what extent the government should intervene in the economy through regulation. Article 119 of the Constitution of the Republic of Korea has its basis on the principle of free market economy, exceptionally allowing the government to intervene and coordinate in certain situations. The Constitution empowers the government with the authority of regulation and coordination to execute the Constitutional value of guaranteeing and securing fundamental human rights. Therefore, the government, as a fair and just mediator, should perform its mission to democratize the economy as well as secure market freedom and creative initiative.

This paper entirely explains the Korean astronaut program from astronaut selection to launch and return and introduces technology and results through this program in detail. The Korean astronaut program launched Nov. 2005 with the objectives to develop the manned space technology such as astronaut selection, training and space experiment and to disseminate concerns to the public about the science and space. In 2006 to select the Korean astronauts, the standards for selecting astronauts were set and then the selection processes from 1st stage to 4th stage were performed. In 2007, the 2 Korean astronauts took the astronaut training and the 18 domestic science experiments and 3 international experiments which the Korean astronaut, Dr. Yi, performed in ISS last April were developed. In April 2008, the Korean astronaut was transported to ISS by Soyuz in Baikonur in Kazakhstan and returned to the ground with performing the mission and space experiments. This paper will explain these processes as the above(astronaut's selection, training, space experiment, etc.) in detail.
University has various resources such as intellectual human resource, spatial resource and facilities, and economic resource. At the same time, universities are, in general, found upon fundamental mission of public service, as well as teaching and research. Recently in Korea, it has been argued that we should make use of such resource of universities in the process of urban regeneration through university-community partnership. Yet, these arguments are lack of concreteness: 'which' kind of resource for 'what' kind of problem, and 'how'. Therefore, this research examined the case of university-community partnership in Japan and tried to find of some implications to Korean society. The reason for examining Japanese case is because Japan has experienced similar problems that Korea face such as aging population, decrease in the number of student, deteriorations of existing urban area; there are respectable amount of similarities between Japan and Korea in political, social and economic context; and because Japan has proceeded regeneration of communities through university-community partnerships.

As the logistic environment of digital contents is rapidly changing, the protection of the digital rights for digital content has been recognized as one of critical Issues. Digital Right Management(DRM) has taken much interest Internet Service Provider(ISP), authors and publishers of digital content as an interested approach to create a trusted environment for access and use of digital resources. This paper propose an interested digital rights protection scheme using license agent to address problems facing contemporary DRM approached : static digital rights management, and limited application to on-line environment. We introduce a dynamic mission control technology to realize dynamic digital rights management. And we incorporate license agent to on- and off-line monitoring and tracking. The proposed system prevent illegal access and use by using PKI security method, real time action monitoring for user, data security for itself.

The relationship between education and work is of the greatest concern to individuals and society because they are the key drivers of growth and development. In the context of Industry 4.0, labor and educators are facing the challenges of big changes in the workplace. How to prepare undergraduate students for the world of employment has become the most important mission of higher education providers. This paper explored the competency gap in the labor market in Vietnam from the perspective of employees who have been dissatisfied with the current status. First, a qualitative method with the Delphi technique was applied to confirm this consensus in an employees' competency model. Then, the satisfaction level for each competency criterion was explored by applying the advance quantitative method, namely, best non-fuzzy performance approach. Lifelong learning was ranked first, followed by creativity and innovation, foreign languages, expertise and digitalization, adaptability, and finally, organizing and managing ability. Critical thinking and problem-solving were perceived to have the biggest gap. The order of competency satisfaction is useful in explaining the mismatch between education quality and labor market demand. The findings provide valuable guidelines for education managers who seek to bridge the competency gap and improve education quality.
Over the past two decades suicide terrorism has become an ever-widening phenomenon. When suicide terrorism was first introduced in the Middle East it seemed that this new phenomenon was invincible and that it might change the innate imbalance between terror groups and their rivalry governments. This did not in fact occur. Looking at history of terrorism, it can be seen that suicide attacks are in actuality a very old modus operandi. However, contemporary suicide terrorism differs from such historical tactics, just as the whole phenomenon of terrorism differs from ancient modes of warfare. Modern suicide terrorism is aimed at causing devastating physical damage. through which it inflicts profound fear and anxiety. Its goal is to produce a negative psychological effect on an entire population rather than just the victims of the actual attack. The relatively high number of casualties guaranteed in such attacks, which are usually carried out in crowded areas, ensures full media coverage. Thus, suicide terrorism, ranks with other spectacular modus operandi such as blowing up airplanes in mid air or the use of Weapons of Mass Destruction as a sure means to win maximum effect. For the purposes of this paper a suicide terror attack is defined as a politically motivated violent attack perpetrated by a self-aware individual (or individuals) who actively and purposely causes his own death through blowing himself up along with his chosen target. The perpetrator's ensured death is a precondition for the success of his mission. The greatest potential risk suicide terrorism may pose in future is if terrorists carry out operations combined with other spectacular tactics such as blowing up airplanes or the use of Weapons of Mass Destruction. Such a combination will increase immensely the death toll of a single terror attack and will have a shocking psychological effect on public moral. At this level suicide terrorism would constitute a genuine strategic threat and would probably be confronted as such. This study portrays a general overview of the modern history of suicide terror activity worldwide, focusing on its main characteristics and the various aims and motivations of the terror groups involved. In addition, This study provides an overview what is to be done to prevent such terrorist attacks.

Wood-based composite panels such as plywood, particleboard (PB), or medium density fiberboard (MDF) are mostly used in the lamination on their surface for the manufacturing of furniture, or interior building products, the concern on the formaldehyde emission (FE) from the surface laminated wood panels is increasingly attracting attentions from the public. Thus, this study was conducted to understand influence of surface laminating materials to the FE from PB and MDF with or without edge sealing, using 24-hour desiccator method. Both PB samples that had been laminated on their surface with low-pressure laminate (LPL) or polypropylene (PP) film and MDF that had been treated with poly(vinyl chloride) (PVC) or coating were tested for the FE with or without edge sealing. As expected, the FE of PB with the sealed edges decreased to 37.4% and 80.7% with the LPL and PP lamination, respectively. The surface laminated MDF with the sealed edges also showed a decrease in the emission up to 57.8% and 54.3%, with the PVC lamination and coating, respectively. However, the coated MDF samples showed 5.3% increase in the emission when their edges were not sealed, indicating a FE form the solvent used for coating. These results showed that the type of surface lamination materials on wood-based composite panels has a great impact on their resultant FE, indicating that the influence of surface laminating materials should be taken into consideration for the formaldehyde mission measurement.
Purpose The business ecosystem perspective offers a new lens in which to view customers. Customers as the member of business ecosystems influence firms by participating in both the firm level activities and the business ecosystem level activities. For example, customers participate in the business ecosystems by forming interest groups, allowing their voice to be heard the within business ecosystems. Customers can also, turn public opinion around and foster the business ecosystems favorable to firms. On the other hand, as an extreme case of customer participation, customers can engage in community activities to boycott the purchase of products or services from certain firms or business ecosystems. Design/methodology/approach This study views content creation and feedback activities as customer participation in the firm level. On the other hand, word-of-mouth (WOM) and boycott activities are considered as customer participation in the business ecosystem level. This study presents a research model regarding the relationships among customer socialization, customer participation, and psychological ownership. The proposed model is validated through an empirical analysis on online platform business ecosystems. Findings When the two business ecosystems are compared, different results were drawn. In the Facebook ecosystem, boycott and psychological ownership did not have a significant relationship. However, in the Kakao ecosystem, the two had a significant positive relationship. The mediating effect of the business ecosystem type sheds a light on the mission, purpose, vision, and other values associated with the theory of the business on the customer-firm relationship. Further implications for theory and practice were discussed in this study.
