The Korean game industry has stopped growing due to internal and external instability. It is the fourth industrial revolution that has been mentioned as a new breakthrough in the domestic game industry in front of these internal and external instabilities. The fourth industrial revolution is changing the paradigm of the existing industrial structure, and has brought ecological changes not only to the manufacturing industry but also to the contents industry as a whole. In this paper, we will explore the development direction of domestic game industry through the 4th industrial revolution and study the relation between development of AI and AR / VR and game industry which will be the main core of the fourth industrial revolution in the future.

This study examines the impact of corporate tax, a fiscal measure along with trade liberalization and research and development on total factor productivity for a panel of 153 industrial firms listed on the Pakistan Stock Exchange over the period 1997-2017. For empirical analysis, we employ the system generalized method of moment estimator. In the first step, we estimate industrial production function and the results reveal that raw material, industrial labour force and energy play vital role in enhancing industrial production. Whereas, industrial capital exerts negative impact on industrial output. We also measured total factor productivity using the production elasticities. In the second step, we examine the impact of corporate tax, trade liberalization and research and development on total factor productivity. The results indicate that higher level of corporate tax exerts negative impact on total factor productivity. The findings reveal that higher corporate taxation discourages industrial firms to undertake research and development thereby exerting adverse impact on total factor productivity of firms. The impact of trade liberalization proxied by average tariff is positive while customs duty and sales tax negatively impact firm-level total factor productivity. These findings provide useful insights for managers, investors and policy makers in Pakistan.

Since the announcement of President Klaus Schwab's fourth industrial revolution at the World Economic Forum in Davos, Switzerland in January 2016, the fourth industrial revolution has emerged as a hot topic in our society. The United States, Japan, China, and Germany, which are major advanced nations, are preparing and implementing a strategy and system for responding to the Fourth Industrial Revolution, focusing on information and communication technology (ICT) and manufacturing convergence in response to the fourth industrial revolution era. Korea is announcing the expansion of financial support for R & D investment budget and related industries for major technology related to revolution. In this paper, we analyze the defense R & D project procedure of the Defense Improvement Project, which is responsible for the development of the defense weapon system, and present the development direction of the defense weapon system in accordance with the 4th world industrial revolution trend.

Engineering valuation is a specialized discipline requiring expert knowledge and judgment, which scientifically estimates the economic value of industrial properties. By industrial properties, we mean engineering structures such as mines, factories, buildings, machines, and other industrial facilities as well as facilities of public enterprises. Particular industrial properties can have longer economic life if their performance is excellent and they are still suitable for current manufacturing needs. If not, its economic life will be shorter. As speed of technological progress becomes rapid, life-cycle and development period of a product is becoming shorter. In an industry characterized by rapid development of technology, industrial properties can become obsolescent faster. Even if they are in good working order, they could be no longer suitable for manufacturing new products based on radically different technology. In our research, we apply engineering approach to estimating functional economic life by factoring in technological obsolescence in such an industry.

BACKGROUND: It has been reported that the nutritional composition of Locusta migratoria (Orthoptera: Acrididae) changes nutrients depending on the host plants. In this study, to confirm whether Locusta migratoria is an edible insect, the nutrients and harmful substances such as heavy metals and pathogens were analyzed and compared according to corn (LC) or wheat (LW) as host plants. METHODS AND RESULTS: All experimental methods mainly referred to AOAC (2004). The content of crude protein per dry weight was 77.3% in (LW), 1.1 times higher than 69.8% in LC. Crude fat was 6.5% in LW, 2.2 times less than LC 14.3%. Alpha-linolenic acid, which has the highest content among unsaturated fatty acids, was 1.2 times higher in LC (39.9%) than LW (32.5%). As a result of analysis of harmful substances by LC and LW, lead and cadmium among heavy metals were at levels suitable for heavy metal standards of edible insects, and arsenic was not detected in both groups. E. coli and Salmonella spp. were not detected in both groups. CONCLUSION: When comparing the overall nutrients composition of LW and LC, it was confirmed nutrients are different depending on the host plants, and the safety was proved.

Novel food sources have enormous potential as nutritional supplements. For instance, edible insects are considered as an alternative food source due to their higher protein content; moreover, they are economically efficient reproducers and have high in nutritional value. In this study, we investigated the toxicity of the freeze-dried powder of Locusta migratoria (fdLM), known to contain rich proteins as well as fatty acids. The objective of the present study was to evaluate the subacute toxicity of fdLM in male and female Sprague-Dawley (SD) rats. The SD rats were divided into four groups based on the dosage of fdLM administered: dosage of 0 (vehicle control), 750, 1,500, and 3,000 mg/kg/day were administered for 28 days. Toxicological assessments including observations on food consumption, body and organ weights, clinical signs, mortality, ophthalmologic tests, urinalyses, hematologic tests, clinical chemistry tests, gross findings, and histopathology tests were performed. Clinical signs, urinalyses, hematology, serum biochemistry tests, and organ weight examinations revealed no fdLM-related toxicity. The no-observed-adverse-effect level for fdLM was higher than 3,000 mg/kg/day in rats of both sexes; therefore, fdLM, in conclusion, can be considered safe as an edible alternative human and animal food source material.

As the market rapidly changes, the speed of new product development is highlighted as a critical element which determines the success of firms. While firms endeavor to accelerate the development speed, frequent iterations in a development process hinders the effort of acceleration. For this reason, many previous researches tried to find the optimal structure of the development process which minimizes the number of iterations. However, such researches have a limitation in that they can be applied to only a single-project environment. In a multi-project environment, waiting time induced by lack of resources also delays the process as well as the iterations do. In this paper, we propose dynamic sequencing method focusing on both iterations and waiting time for reducing the durations of development projects in a multi-project environment. This method reduces the waiting time by changing the sequence of development tasks according to the states of resources. While the method incurs additional iterations, they are expected to be offset by the reduced waiting time. The results of simulation show that the dynamic sequencing method dramatically improves the efficiency of a development process. Especially, the improvement is more salient as projects are more crowded and the process is more unbalanced. This method gives a new insight in researches on managing multiple development projects.
