While South Koreans overseas travelling rate has been increased every year, domestic travelling rate has been at a standstill for several years. The purpose of this study is to analyze domestic traveling styles of Koreans according to their generations in order to provide generation-specific traveling services. For this purpose, we categorized the survey respondents into four different generations, which are Millennium (age 19~34), X generation (35~54), Baby Boomer (55~64) and senior by following the criterions of the Korea National Tourism Organization. After then, we analyze factors related to travel preparation process, the actual traveling activities and satisfaction after the travel. In this study, 16,713 data collected by the Ministry of Culture, Sports and Tourism are used. The results of this study show that Korean people tends to acquire domestic traveling information from their own or acquaintances past experiences. Also, they do not prefer the organized trip for domestic travels, thus do not buy package products a lot. In addition, natural scenery, rich in cultural heritage, and convenient accommodation are the most important determinant factors affecting the overall travel satisfaction of level for all generations. The traveling characteristics for each generation are as follows. Millennium get traveling information from the internet a lot, and more specifically, they refer portal sites and social network services (SNS) in many cases. Also, they tend to travel in summer peak season to popular destinations and pursues active traveling experiences. Generation X has similar traveling patterns with Millennium, however they major transportation method is using their own car. Also, transportation convenience and satisfactory leisure activity are important factors affecting the overall satisfaction level to Generation X. On the other hand, Baby boomer generation has a greater emphasis on appreciation of nature, visiting famous restaurants, and relaxation, rather than actively participating experiencing programs. They travel evenly in summer and spring/fall season to many different areas instead of focusing on popular tourist spots. In addition, shopping and eating delicious food are the important factors affecting the overall satisfaction level for them. Lastly, Senior generation has similar characteristics with Baby boomer in many ways, however, they travel a lot on the same day using public transportations or car rental service. They prefer spring and autumn trips rather than summer peak season, and tend to buy packaged travel products a lot compared with other generations. If these different traveling characteristics of each generation are considered for organizing and customizing tourism services, it is expected that domestic tourism satisfaction level will be ultimately increased.

The objective of this study was to investigate the influence of family-related factors and age-friendly environment on intergenerational interaction in middle-aged group and the older adult group. Based on the results, this study is to suggest countermeasures for decreasing intergenerational interaction with the population aging. This study analyzed 260 sample participants aged from 45 to 64 and 399 sample participants aged 64 and more, categorizing them into middle-aged group and the older adult group respectively. The sample participants were taken from '2014 Survey on the Aged Society' and had at least one adult child aged over 18 at the time of participation. In order to identify the relationship between five sub-dimensions related to family, age-friendly environment and intergenerational interaction within the family in two age groups, t-test and multiple regression analysis were used. As a result, both two family-related factors had positive correlation with intergenerational interaction within the family. However, affective solidarity showed a higher significance in the middle-aged group and familism showed a higher significance in the older adult group. Among the sub-dimensions related to age-friendly environment, only personal opinion on age integration showed significance in the older adult group. This study provides several implications from the results.

The objective of this treatise is to explore the limitations of the current navy manpower utilization system and the ways to improve it from the perspective of Generation Z. As Generation Z, following Millennials, has finally come of age, this new group is constituting a gradually greater proportion of military personnel. Due to the typical characteristics of naval operations, the harmony between Millennials and Generation Z, which is differentiated from Generation X in view of dispositions and traits, is one of the essential issues to be discussed. Generally, in a naval vessel, there are numerous pieces of equipment necessary to carry out a wide range of missions and a large number of crew members who operate them with consistent levels of fighting power. This is all while members are living together within the narrow space throughout the 24 hours of each day. Under such particular circumstances, any inter-generational conflicts may have a disruptive effect on the successful accomplishment of naval missions. Currently, new generations of military personnel are facing social difficulties in different aspects compared with the previous generations, and also have different viewpoints on the military. In this regard, in order to foster true harmony between generations, it is considered necessary to take a closer look at the inter-generational differences from their respective standpoints and to examine whether the military organization has taken adequate steps to respond to such changes. Accordingly, Chapters 1 and 2 cover the environments in which Millennials and Generation Z were raised during their childhood to young adulthood, which are distinct from those of older generations, their viewpoints formed based on such backgrounds, and the need to resolve various conflicts between generations. In Chapter 3, the current actions taken by overseas military powers to enhance the coexistence with Generation MZ are analyzed to find the significant implications they had. Chapter 4 examines the operation environments specific to the navy; identifies the potential barriers to achieving harmony between generations by assessing the current status of personnel utilization in the Korean navy in terms of the seaman, petty officer, and the officer, as well as policy; and outlines the solutions to drive harmony. Finally, Chapter 5 emphasizes the need to establish a genuine empathy between generations based on the understanding of unique inter-generational characteristics. This section also discusses the importance of addressing difficulties in utilizing technology-centered naval manpower, and forecasts a scenario of a naval organization that resolves the problem of utilizing naval personnel and the inter-generational conflicts in the future.

Using Korea Labor and Income Panel Surveys data, this paper estimates the effect of schooling level on income over time and the effect of children's education level on intergenerational income persistence. The results show that the impact of education level on income decreased over time. Also, intergenerational income persistence, measured as a dummy variable that has value one if children's income percentile group is same as the father's, increased with children's educational attainment only when the father is in upper income percentile groups. These findings indicate that education fails to play a significant role of the economic ladder and does not much help in raising intergenerational income mobility. Rather, education may possibly function as a means of intergenerational transmission of wealth through parental investment in their children's private education.

Korean military is propelling the M&S on new warfare concept, such as NCW(Network Centric Warfare) which is the aspect of future war. IPv6 is the essential element of next generation defense network which is supporting the future battlefield. There have been many studies on allocating the IPv6 address for next generation defense network. However, they assigned the address by level on the basis of the military organization or assigned it from the service network, so it had the defect, the big size routing table. This study reviews the topology of next generation defense network and adjusts the position of service network ID on the basis of the network topology. Finally, it improved the efficiency of route aggregation and minimized the routing table size in comparison with the previous studies and it was proved by OPNET simulator.
