Different methods of cold storing of bivoltine eggs are in practice to postpone hatching. Bivoltine eggs undergo hibernation if they are not acid treated within 20 - 24 hrs of oviposition, which depends on race, ambient temperature and humidity. The schedules adopted for cold storing include hibernation schedule (Hib), ordinary chilling (OC), short term chilling (STC) and acid treated layings (AT). Peanut cocooning race ${NB_4}{D_2}$ has been subjected for the present assessment. Cocoons harvested from the crop pertaining to all the four methods of cold storing have been used for producing different combinations and acid treated followed by rearing. The performance in respect of chawki loss, maximum larval weight 4({5^th} age)$, yield/ 10,000 larvae (no), cocoon and shell weight showed maximum values for hibernation ${\times}$ hibernation combination followed hibernation with OC and hibernation with AT. Lowest performance was recorded when STC batch source females were used.

The term 'fourth industrial revolution' was mentioned at the World Economic Forum (WEF) in 2016 and has become a term representing a new industrial era based on information and communication technology (ICT). In the environment of the 4th industrial revolution, ESG management activities are becoming a very important factor in business activities. With the emergence of a new paradigm of organizational operation in the post Covid19 era, the demands for ESG (Environment, Social, Governance) investment related to the environment, social responsibility are increasing. This study examines the role that can support ESG management by utilizing the expertise of appraisers. Real estate is one of the fields of high public interest, and since most ESGs have been conducted centered on the role of private companies, the role of the expert group or the role of public corporations and public institutions is relatively insufficient. If a company or general company engaged in the real estate investment business establishes the role of the Korea Appraisers Association to revitalize ESG management using appraisers, such as ESG appraisers, when investing in real estate, it is believed that it will be possible to promote efficient and sound development of the real estate industry. It was judged that a study on a group of experts was also necessary. In addition, even if the impact of Covid-19 is excluded, it is necessary to gradually introduce an appraisal using non-face-to-face or various advanced technologies (the 4th industry). This study differs from previous studies in that it focused on the role of ESG by the Korea Association of Property Appraisers while research on the role of ESG in public institutions or expert groups is being actively conducted in recent years.

In the 4^th Industrial age, mobile games are a highly competitive but highly profitable industry, with hundreds of games per day. To produce a successful mobile game, it is necessary to understand the mobile environment and consumers in the mobile era, and a study that can provide implications for the importance of various factors is needed. The purpose of this study is to explore the in- and out-of-game factors that influence the success of mobile games and to examine the relationship between these factors and customer satisfaction and loyalty. As a result, the game platform's system quality and service quality had a positive effect on the evaluation, and the price policy did not have a significant effect on the evaluation. Also in the flow factor, goal and interaction (relationship) had a positive effect on the flow, and skill or challenge did not have a significant effect. The effects of flow and platform evaluation on customer loyalty were all positively affected. First. Companies must derive customer opinions and actions about the game through continuous interaction with customers. Second, if the game gives customers the proper goals and functions to enable the interaction between users, more successful games can be developed.

In the era of the 4th Industrial Revolution customers living began to come out, not inside the purchase funnel. Due to the diversity of product selection and the increase in digital channels, the way customers search for information and purchase it is changing innovatively. So, the customer journey in the digital age is much more complicated than the traditional funnel model suggests. Unlike many previous studies, this study was conducted for 1,200 customers in four product groups of fashion, automobile, cosmetics, and online shopping malls. As a result of the study, we investigated how digital self-efficacy plays a role in purchasing in a series of processes in which digital experience affects customer satisfaction and finally affects purchase. As a theoretical implication, as a result of introducing and testing digital self efficacy as moderated mediation effect. the digital self-efficacy between customer satisfaction and customer loyalty were determined to play a moderated mediation effect role. As a practical implication, it was necessary to actively utilize digital marketing for customers with high digital self-efficacy, but it was suggested that customers with low digital self-efficacy need to be careful about digital marketing fatigue.

The battlefield environment of the Korean peninsula is rapidly changing due to the advancement of the weapon system brought by the political situation of adjacent countries and the 4th industrial revolution. The reduction of population also caused a sharp drop in the recruitment of military personnel, making it unavoidable to reform the military structure. This meaningful study is timely with recent news reports on the shortage of recruitment by 10,000 persons in the last five years. Universities are also seeing a decrease in the number of new students due to the reduced school-age population, and affiliated universities are responding to this issue with great seriousness. With a reduction in manpower, requirement-handling military units need to step up their efforts to secure competent noncommissioned officers while affiliated universities must also train capable noncommissioned officers. As a solution to the matter at hand, this study aims to suggest a method that may vitalize both the navy and the navy-affiliated universities based on the results of literature research.
