This convergence study was conducted to identify the effect of the awareness enhancing program of the international development cooperation of college students sponsored by the Korea International Cooperation Agency (KOICA). A quasi-experimental study design was used. The participants consisted of one experimental group (n=32) who attended the awareness enhancing class of international development cooperation and the other control group (n=32) who did not participate in the class in a university in C city. The data were collected using online survey before the first class and after the last class in spring semester 2019. Collected data were analyzed by ANCOVA using SPSS WIN Version 20.0 program. The levels of global citizenship (p=.003) and career preparation behavior (p=.013) was higher in the experimental group than in the control group. However, career identity(p=.385) and cooperative efficacy(p=.488) did not show significant difference between the groups. This study proposed the direction for the awareness enhancing program of the international development cooperation of college students by showing its positive effects on the global citizenship and career preparation behavior.

Analysis of combat effectiveness is required to consider the concept of tactical cooperative engagement between manned-unmanned weapon systems, in order to predict the required operational capabilities of future weapon systems that meets the concept of 'effect-based synchronized operations.' However, analytical methods such as mathematical and statistical models make it difficult to analyze the effects of complex systems under nonlinear warfare. In this paper, we propose a combat simulation model that can simulate the concept of cooperative engagement between manned-unmanned combat entities based on wireless communications. First, we model unmanned combat entities, e.g., unmanned ground vehicles and drones, and manned combat entities, e.g., combatants and artillery, considering the capabilities required by the future ground system. We also simulate tactical behavior in which all entities perform their mission while sharing battlefield situation information through wireless communications. Finally we explore the feasibility of the proposed model by analyzing combat effectiveness such as target acquisition rate, remote control success rate, reconnaissance lead time, survival rate, and enemy's loss rate under a small-unit armor reconnaissance scenario. The proposed model is expected to be used in war-game combat experiments as well as analysis of the effects of manned-unmanned ground weapons.

This study analyzed the effect of cooperation activities among SMEs. In order to study empirical analysis, we classified the types of cooperation into four dimensions: technology cooperation, human resource cooperation, sales cooperation and financial cooperation. Review the role of the collaborative philosophy as a predictor. This study also analyzed the relationship between cooperation philosophy, cooperation activities and performance. The results of this study are as follows: First, the result of path analysis between cooperation philosophy and cooperation activities shows that cooperation philosophy has an important influence on technical cooperation, human resource cooperation, sales cooperation and financial cooperation. Second, the results of the relationship between cooperation activities and achievements, technical cooperation, human resource cooperation, and sales cooperation have an important influence on cooperation performance. The meaning of this study is as follows. Analyze empirical tests using the PSBP model from a partnership perspective. We are trying to verify the relationship with SMEs. Therefore, we can suggest a beneficial implication to explain the importance of cooperation activities between SMEs. Also, SME business units have a problem with technical information leakage when they form partnerships, but in order to overcome this problem, we can use cooperative philosophies and avoid negative views.

Our society has been dominated by the Dilemma Theory that rational individuals cannot get out of the 'Tragedy of the Commons' without helps from state or market. However, many empirical researches have discovered cases that common pool resources could be managed by cooperative methods of community. Based on the possibility of managing common pool resources by residents' cooperation/solidarity revealed by the recent case researches, this study aims to seek for the theoretical basis to prove it. Generally, public policies are carried forward based on the theoretical basis of the relevant social issues. The objective of this study is to suggest the new direction of policies related to domestic common resources through the researches on community's role in managing local common pool resources represented as "scenic spot". For this, it aims to reveal the influence of community activity on behavioral intention of local common pool resources, by drawing/quantitatively measuring measurement items of local residents' community activity on top of attitude, norms, and behavioral control suggested by the existing Theory of Planned Behavior. The results of this study are as follows; 4 factors such as attitude toward behavior, subjective norm, perceived behavior control, and community activity were all factors that influenced intention to manage.

In opportunistic network, the behavior of a node is autonomous and has social attributes such as selfishness.If a node wants to forward information to another node, it is bound to be limited by the node's own resources such as cache, power, and energy.Therefore, in the process of communication, some nodes do not help to forward information of other nodes because of their selfish behavior. This will lead to the inability to complete cooperation, greatly reduce the success rate of message transmission, increase network delay, and affect the overall network performance. This article proposes a hybrid incentive mechanism (Mim) based on the Reputation mechanism and the Credit mechanism.The selfishness model, energy model (The energy in the article exists in the form of electricity) and transaction model constitute our Mim mechanism. The Mim classifies the selfishness of nodes and constantly pay attention to changes in node energy, and manage the wealth of both sides of the node by introducing the Central Money Management Center. By calculating the selfishness of the node, the currency trading model is used to differentiate pricing of the node's services. Simulation results show that by using the Mim, the information delivery rate in the network and the fairness of node transactions are improved. At the same time, it also greatly increases the average life of the network.

Milk protein concentrate (MPC) is widely used to enhance the stability and texture of fermented dairy products. However, most research has focused on yogurt products, and the effects of MPC on sour cream characteristics remain unknown. Therefore, we investigated the effects of different MPC levels (0%, 1%, 2%, and 3% w/w) on the rheological, physicochemical, microbiological, and aroma characteristics of sour creams in this study. We found that MPC supplementation stimulated the growth of lactic acid bacteria (LAB) in sour creams, resulting in higher acidity than that in the control sample due to the lactic acid produced by LAB. Three aroma compounds, acetaldehyde, diacetyl, and acetoin, were detected in all sour cream samples. All sour creams showed shear-thinning behavior (n=0.41-0.50), and the addition of MPC led to an increase in the rheological parameters (η_a,50, K, G', and G"). In particular, sour cream with 3% MPC showed the best elastic property owing to the interaction between denatured whey protein and caseins. In addition, these protein interactions resulted in the formation of a gel network, which enhanced the water-holding capacity and improved the whey separation. These findings revealed that MPC can be used as a supplementary protein to improve the rheological and physicochemical characteristics of sour cream.

The state behavior has a strong consequence with the national strategic culture. However, different scholars hold different views on the classification of the national strategic culture. As one of the most significant land neighbors in West China, Pakistan is China's all-weather strategic cooperative partner. Understanding Pakistan's strategic culture will not only help understand Pakistan's national policies and state behavior, but also help deepen China-Pakistan cooperation. Cutting in from the perspectives of geography, social economy, culture, history and military, the author believes that the formation mechanism of Pakistan's strategic culture is mainly affected by the following four factors: geopolitical environment, production mode and lifestyle, cultural tradition, historical experience and diplomatic relations. The analysis has found that Pakistan's strategic culture has been shaped by Islam and can be classified as an outward-oriented strategic culture, the state behavior also shows a strong Islamic identity.
