Assuming the united Korea, total population is estimated to be 70 million and grain demand for the people is estimated to reach 30 million metric tons. Cultivated land in North Korea is about the same as South Korea i.e. 2 million hectares. However grain production in North Korea is about one half of South Korea's, 6 million metric tons in the South and 3 million metric tons in the North a year. This implies that the United Korea need to import more than 20 million metric tons of grain a year and it will trigger many economic and social problems for the United Korea. In order to meet deficient grain supply, the United Korea can choose three possible policy options; importation of grains or increased investment in foreign agricultural development or increase in domestic supply Among the possible policy options, increase in domestic supply is desirable and can be achieved by developing North Korea's grain supply potential. North Korean agricultural development can also be achieved most effectively through cooperation between the South and North. An effective policy option for agricultural cooperation between the South and North is supply of agricultural inputs such as fertilizer and pesticides and exchanges of agricultural technology. Cooperation between the South and North in the agricultural sector should be achieved and developed further to solve the potential food problem before unification.

This study aims to establish a development strategy for higher education in Indonesia's marine and fisheries sector and to present a direction for international development cooperation through evaluating policies and current problems related to higher education in marine and fisheries sector. To achieve the goals of human resources development in marine and fisheries sector, Indonesian government needs to secure non-salary expenditures to strengthen support for areas directly related to the effects of education, such as improving educational facilities, expanding scholarships, and so on. Education institution needs to develop effective teaching methods and systematic practice-based curriculum that reflects the needs of the local fishermen community and fisheries industry. In addition, it is necessary to support the supply of manpower throughout the fisheries industry. Fisheries industry needs to stop relying on the government or education institutions to secure excellent human resources and actively participate and cooperate in the education field so that excellent human resources can flow into the industry. Based on this strategy, international development cooperation for human resources development in Indonesia's marine and fisheries sector should focus on qualitative rather than quantitative expansion of higher education institutions.

This study was conducted to propose creative innovation systems. The effect that cooperation network factors of innovation system in telecommunications sector called typical knowledge industry have on technological innovation was examined. We used the Korea Corporate Innovation Survey (KIS) Data for this study, it has to apply the OECD NESTI-WPIA methodology for probit analysis. The analysis derived the following findings. First, cooperation between the principal innovations in the telecommunication information generally have a positive impact on innovation. Second, cooperation with private institutions have an important role in technological innovation. Third, the various cooperation exerts a positive impact on innovation and has a greater impact on practical innovation in a low creativity level. With this result, it seems that our technological innovation policy should follow a direction of building corporatist-type system to establish cooperation promotion, privately led innovation, and a variety of opinions.

This paper is designed to make a national strategic concept for the ROK's maritime security and to explore cooperation directions for the ROK Navy and Coast Guard in order to implement the newly-made maritime security strategic concept. As strategy is composed of three main categories(goals, ways, means), the goal of the ROK's maritime security strategy is 'Safe and Affluent Sea' and the way to realize the goal is the principle of cooperative leverage, and the means as tasks to implement the strategic concept are maritime safety, maritime security, and maritime stewardship. The concept of national fleet as used in the US is applied to promoting the cooperation between the ROK Navy and Coast Guard. Thus, under the newly-established maritime security strategic concept along with the national fleet model, followings are suggested as policy proposals for facilitating mutual cooperation between the ROK Navy and Coast Guard in dealing with not only traditional threats but also non-traditional treats at sea and from the sea as well. First, the ROK Navy and Coast Guard has been making efforts to enhance interoperability between the two sea services. However, the mutual cooperations have been focused mainly on areas on operational level rather than policy level. Therefore, the two sea services are recommended to enlarge exchanges and cooperation in policy areas. Second, there are still demands for further cooperation areas between the two sea services in command and communications. The interoperability in C2 between the two needs to be upgraded even to the areas of anti-terrorist activities ar sea, ASUW, ASW, maritime interdiction, etc. Third, mutual comparability between the two needs to be reflected in the maritime forces development to ensure the comparability in UNREP and other logistics areas. Fourth, the standardization of logistical materials and equipments is needed as a way of sustaining operational capability and logistical capacity for the ROK Navy and Coast Guard as well. Fifth, the ROK Navy and Coast Guard are recommended to participate more actively in international maritime cooperation activities such as PASSEX. Sixth, Complementary laws and regulations need further to be revised and to be newly made for collectively managing swiftly maritime accidents and natural disasters at sea.

This paper proposes a method of designing the main parameters of the Teflon coating equipment of a guide wire used in medical treatment. The proposed device was designed to be guided by a reel-to-reel method in which the guide wire performs all processes continuously, such as Teflon coating and heat treatment. At this time, the conveyed guide wire vibrates between the rollers, which affects the quality of the coating. Therefore, this paper proposes a dynamic equation of the guide wire to be transported in the longitudinal direction, and design parameters setting method of the feed speed and the interval of the roller supporting the wire is proposed to minimize the vibration amplitude of the guide wire during transport. The Teflon coating of the medical guide wire was carried out based on the developed coating equipment. The target coating thickness of the guide wire was set to less than $10{\mu}m$ in the circumferential direction, and the results were examined by optical microscopy.

As the application fields using various types of communication, including the Internet of Things, have emerged, the form of communication has been diversified. Some applications require fast feedback and the others continue to send data regardless of whether it is received or not. Transmitting data in one way can be acknowledged by the opposite direction response. These information exchanges form a two-way communication. For applications that need to issue commands remotely, such as network control systems, it is important to give a fast response because the sender decides the next action based on the response from the recipient. In this paper, we propose the base station (BS) cooperation to improve the latency performance of the two-way communication in cellular networks. We design the two-way communication strategy utilizing cooperating BSs with the same direction of traffic as well as bidirectional traffic. We show that the proposed scheme improves the latency performance than the previous works.

Background: The establishment of a strategy for the reduction and prevention of oral disease, a global pervasive disease, is considered one of the important national health policy strategies. In Korea, the 5th Comprehensive National Health Promotion Plan is currently in progress, but there is insufficient research on the transition process or improvement direction in the field of oral health. Methods: Changes in Comprehensive National Health Promotion Plan's Oral health sector in three countries were compared, and the direction of the three countries (Korea, the United States, and Canada) in accordance with the recent Oral health paradigm was confirmed. In this study, we reviewed the existing literature using the narrative review method to draw implications for strategies and directions for oral health promotion in Korea. Results: In Korea, the oral health promotion strategy is included in the 5th Comprehensive National Health Promotion Plan, and the project is being led by the government. The United States prepared a national-led oral health promotion strategy and suggested multi-disciplinary cooperation to improve overall oral health and reduce the oral health inequality. For more active intervention, Canada established an oral health-related department and assigned experts, while emphasizing cooperation between the government and the private sector. Conclusion: As a result of this study, Korea is also making efforts to improve oral health, but more active government intervention is needed to reduce the inequality in oral health by population group. To this end, it is necessary to establish a strong multi-sectoral cooperation system and prepare a strategy for implementation.

This paper proposes an improved de-interlacing method that converts interlaced images into progressive images from one field. First, it calculates inter-pixel values applying third-order spline interpolation for the horizontal direction from four upper lower pixel values of missing pixels. From inter-pixel values obtained from spline interpolation and upper lower pixels with value, the proposed method makes an accurate estimate of the direction by applying the correlation between upper and lower pixels. The correlation between upper and lower pixels is calculated in nine directions of a missing pixel by using values obtained from spline interpolation and pixels with value. The direction of an edge is determined as the direction in which the correlation between upper and lower pixels is at its minimum. Thus, a missing pixel is calculated by taking the average of upper lower pixels obtained from the predicted direction of an edge. From the simulation results, there are problems in that it takes a bit more time for processing, but it is expected that the time problem will be improved by increasing CPU processing speed. As for image quality, it is shown that the proposed method improves both subjective and objective image quality and quantitatively improves picture signal-to-noise ratio (PSNR) in the range between 0.1 dB to 0.5 dB, as compared with previously presented de-interlacing methods.

In this study, the falls detection and direction classification system was implemented using 3-axial acceleration signal. The acceleration signals were acquired from the 3-axial accelerometer(MMA7260Q, Freescale, USA), and then transmitted to the computer through USB interface. The implemented system can detect falls using the newly proposed algorithm, and also classify the direction of falls using fuzzy classifier. The 6 subjects was selected for experiment and the accelerometer was attached on each subject's chest. Each subject walked in normal pace for 5 seconds, and then the fall down according to the four direction(front_fall, back_fall, left_fall and right_fall) during at least 2 second. The falls was easily detect using the newly proposed algorithm in this study. The acquired signals were analyzed after 1 second from generating falls. The fuzzy classifier was used to classify the direction of falls. The mean value of the falls detection rate was 94.79%. The classifier rate according to falls direction were 95.83% in case of front falls, 100% incase of back falls, 87.5% in case of left falls, and 95.83% in case of right falls.
