Demand for information security consulting is increasing as the number of major information infrastructure facilities in the country is increasing and the subject of ISMS mandatory certification is expanded. The demand for manpower also increases, but the manpower to meet the needs of industry is scarce. In order to cultivate the manpower that meets the demand, the demand of the industry should be grasped first. Therefore, this study collected and analyzed job advertisements in Korea and the United States in order to grasp the needs of industry. This will contribute to the development of policy to cultivate human resources of consultants in accordance with the future demand of the enterprise, and ultimately it will be able to solve the quality disparity of security consulting personnel.

Yield management, which originated from the U.S. service industry, uses pricing techniques and information systems to make demand management decisions. Demand uncertainty is an important factor in the area of demand management. A key strategy to reduce the effects of demand uncertainty is substitution. The most generally known type of substitution is inventory-driven substitution, in which consumers substitute an out-of-stock product by buying a similar or other type of product. Another type of substitution is the price-driven substitution, which occurs as a result of price changes. In this research, we consider two market segments that have unique perishable products. We develop yield management optimization models with stochastic demand based on the newsvendor model where inventory-driven and price-driven substitutions are allowed between products in the two market segments. The most significant contribution of this research is that it develops analytical procedures to determine optimal solutions and considers both types of substitution. We also provide detailed theoretical analysis and numerical examples.

The external factors of global flavor market include the world economy, population growth, urbanization, consumer spending, raw material availability, pricing, and regulatory issues. And the internal factors as product pricing and technology development may lie the flavor house's competitiveness and cost considerations. In developing countries, rising preference for packaged food and beverages and increasing personal expenditures will drive demand for flavor market. Increasing consumer demand for natural products, driven in part by health concerns and a desire for transparency in labeling will impact the demand. The increasing demand for salt and sugar reduction will boost demand for flavors to maintain the overall taste. The use of quality and innovative flavors in the beverages and the multifunctional flavors has a positive influence on the global market. The global flavor industry has the presence of several drivers and positive trends, with its future expected to be promising.

This study examines the relationship of the industry-specific factors that effect innovation of manufacturing technology and the market share within the defense industry. Since the establishment of the basic defense industry framework in 1973, there were numerous interactions of the industry-specific factors of the defense industry structure with the technological innovation and market organization of the defense industry. During last three decades, the domestic defense industry has achieved the considerable level but the framework of the basic system has not developed much in areas of the military science and the defense manufacturing technology. Industry-specific factors were formed in the process and appeared in a variety of behavioral characteristics as subsystems. Currently, there IS a growing trend where the management of defense industry is gradually deteriorating due to limitation of the domestic industry-specific factor (e.g. defense technologies, amount of demand, etc.). If there is a prominent imbalance of the industry-specific factors. it can trigger the potential problem of conflict, lack of cooperation and control, slowing the growth of the manufacturing technology thereby diminishing the market and deteriorating the defense supply/demand relationship. In a research conducted by Joe S. Bain, Bain analyzed the relationship of the traditional industrial organization where industry-specific factor(S) not only impacts the conductor(C). And, conductor(C) influences the shaping of the performance(P) of relationship of the traditional industrial organization. Consequently, the researcher has identified the demand monopoly, barriers to entry, and market competition with comparison of defense industry issues. These defense issues were three industry-specific factors identified, which are 1) The demand monopoly and The entry barriers to new market competition, 2) the industrial technical factor to a production technical competitiveness and a market sharing competitiveness, 3) the probability factor to revolution for military affairs(RMA) and a R&D production. According to baseline with these factors, the following research model is established from the special companies group(Group A), the systematization companies group(Group B), and the general companies group(Group 0. The hypothesis is that if there are more industry-specific factors, then there will be more relationships of defense industry relation statutes. This research is an empirical study on the relationship that the industry specific factors effects the innovation of manufacturing technology and the shaping of the market in the defense industry. Moreover, the existing models to evaluate the industry specific factors of the defense industry IS much to be desired with the controlled statistical analysis of the result. It is vital to study on current situation with suggesting alternative strategy to the efficient strategy. The descriptive analysis approach analysis is conducted with SPSSWIN to conduct reliability test, factor analysis, correlation analysis, cross-tabulation analysis, one-way ANOVA, and multiple regression analysis. However, there were some limitations of the survey such as the rigidity of concept about the technical factors and various market management factors. The wishes is that the decision-maker could be utilized these defence industrial factors to formulate efficient defence policy and strategy in the future.

The past quantitative analysis of the demand for job skill training had mainly focused on personnel shortage and oversupply, so it has the problems of the qualitative discrepancies called skill mismatch. As a supplementary study relating to specific industries and occupations, a discussion to improve the job skills training programs through a qualitative analysis is needed. This study provide the analysis of urgency evaluation using the relative importance and gap of the job skill elements in the display industry. And renewal possibilities of the training program based on this qualitative bottom-up approach will be discussed. We carried out a job skill demand survey in the display industry as research methods. Industry related jobs and each job task, the qualitative demand for each job skills, and procurement methods for each job skills were analyzed. Adequate supply of vocational training programs have tried to find ways by illustrating some related training courses.

A university needs to analyze and improve its curricula with the perspective of the consumer to develop a syllabus for the training of industry-demand customized human resources. Accordingly, this paper surveyed the demand of fire-related industry workers to evaluate the major fitness of the curriculum of fire risk prediction and assessment and carried out descriptive statistical analysis, factor analysis, cluster analysis, and one-way ANOVA based on the results. According to the analysis, fire-related industry workers reported that the curriculum of fire risk prediction and assessment is suitable for majors. In addition, they were greatly aware of the necessity of basic major and common major subjects among subjects of fire risk prediction and assessment. The results of this analysis will provide the basic data to improve the curriculum continuously in the future.

The supply and demand of mushrooms has increased dramatically as the standard of living has increased and the nutritional and medical value of the mushrooms has been discovered. However, in meeting the demand, the profitability of the mushroom is being reduced. Even though there are many different types of and uses for mushrooms, the overall output production for the last ten years has consistently increased 5.9% per year, and for the last five years('00~'04) 5.2 % per year, and for the last 3 years('02~'04) 2.9% per year- the rate of increase has slowed. Looking at the standard gross income from mushroom production, it has increased 5.2% over the last nine years('95~'03), 1.6% over the last 4 years('00~'03), and 3.2% over the last 3 years('02~'04)-the annual gross income is decreasing. Even though the farmers are producing more mushrooms, the annual gross income is not increasing enough to keep up with the production, and therefore the profitability of mushrooms is decreasing. Since 2002, the constant increase of the output of edible mushrooms such as the Common Mushroom, Oyster Mushroom, King Oyster Mushroom and Winter Mushroom has resulted in a price declines. Before 2004, Korea mainly exported mushrooms, but after 2004 Korea mainly imported mushrooms. The mushroom industry of Korea is nearing the end of the stage of 'supplying domestic demand.' The stages are as follows: demand raised ${\rightarrow}$ supply domestic demand ${\rightarrow}$ export ${\rightarrow}$ country with developed mushroom industry. Therefore, we should have an efficient system to promote the exportation of mushrooms. Not only the exportation of mushroom itself but also the exportation of mushroom spawn, cultivation techniques and processing facilities should be our goal when we formulate the policy.

This study attempts to analyze the economic impact of the service robot industry using Input-Output analysis, which is conducted based on Demand-driven model, the Leontief price model, the Backward and Forward Linkage Effects, and the Exogenous Methods. In a Demand-driven model analysis, we can conclude that the service robot industry contains characteristics of both the manufacturing industry and the service industry, which causes a positive impact on the overall industry by compensating for the weaknesses of the two industries. The Leontief price analysis indicates when wages in the service robot industry increase, prices related to robot manufacturing also increase. Also, when profits in the service robot industry increase, prices related to service provision increase, too. The Backward and Forward Linkage Effects analysis shows that the service robot industry is highly sensitive to the current economic condition and has a great influence on the service industry. The service robot industry can highlight the aspect of service characteristics when the manufacturing industry is in recession and vice versa. In addition, the service robot industry can be regarded as a value-adding and domestic economy promoting industry which utilizes knowledge of information and communication technologies. It is important to foster the service robot industry in South Korea, which is in economic recession to provide an opportunity to stimulate the growth of both service and robot industries.

The utilization and value of drones are increasing throughout society. However, there was a lack of government support and investment such as lack of technology of domestic drone companies, regulation of loans and lack of technology evaluation items. Therefore, this paper conducts statistical analysis to derive what drone capacity should be strengthened for the drone industry activation in Daegu. As a result, the demand satisfaction(price, quality, service) of drones leads to revitalization of drone industry when the physical, social, and policy factors among drones are strengthened. In conclusion, drone capacity to be strengthened in order to revitalize the drone industry in Korea is based on physical factors(drone demand, development, number of registrations, number of businesses and workers), social factors(national level public relations, establishment of public education institutes, correct understanding of drone occupation, preception), policy factors(privacy measures, government funding, legislation and system easing). As for the three factors, the government, industry, and drone operators are expected to have a bright future when the trinity is improved and complemented.
