The purpose of this research was to find out relation between the attitudes toward work and leisure in later life and intention to move to senior community available to work among 50's in Seoul, Incheon, and Kyunggido. The same research questions would be revealed as the previous one done by Cho & Cho(2006). The data were the part of the survey collected from 556 respondents with questionnaire during November, 2002 by the Hong's research team(2004). The results of this study showed that most respondents were somewhat actively preparing toward work in later life and the level of preparation differed by the individual characteristics such as age, health and occupation. They preferred various work items specially managing facility center, raising animals and plants, and managing educating center, which were different from what current elderly workers were mainly involved in. Similarly to the work, most respondents cared for the kind of leisure activities to continue and saved money for the leisure expenses in later life. The better the economic conditions, the more actively prepared for leisure in later life. They were strongly expected to participate in public leisure facilities and programs for the elderly as a user, volunteer, and/or activist. Over two thirds of the respondents preferred to work and live together in later life and over two out of five had intention to move to the senior community available to work. The more active in work and/or leisure in later life, the higher intention to work together and/or to move to the community. Those results generally supported the previous research showed that the needs of work and leisure in later life would be increased and varied, therefor housing for the elderly should considered work space and program as well as leisure. The further study was suggested to focus on the potential and current residents in the sample case of the comprehensive welfare town for the elderly by local administration.

The main mission of OTM(On-The-Move) satellite communication system is to provide satellite communication service while moving on a vehicle. So it should have a capability to maintain a reliable communication channel when it travels at high speeds or in a severe fluctuation region. This paper presents a small-sized multi-mode monopulse structure applicable to OTM satellite communication system which has only single mode-coupler with a pair of slot using a feature of circular polarized received signal. And tracking error signal is defined using fundamental and high-order modes.

Recent Korean policies have been suggested as globalization, openness and expansion of the working world through k-move. In an era of communication, interest and expectations for overseas employment and advancement into the country are increasing as a way to solve the global trend of employment abroad. Until recently, overseas employment support systems and policies have been implemented in a variety of ways through collaboration with universities and government agencies, so this paper will study Australia's national support and vocational education systems, for example, and Australia's foreign employment conditions and the overall system. This will help overseas employers and policy makers understand the status quo and will be meaningful as additional data needed by Korean universities and policy agencies. On the basis of these data, it was proposed as a conclusion on how to supplement the policy. Through the text, we aim to help establish practical goals and solutions that will help job applicants from overseas Australia, government and university policy systems. Accordingly, the main body presented the policies and assessment methods of the Australian vocational system, the overseas job support system, the corresponding service support system, and the overseas conditions and information on the program, and, in conclusion, the implications of policy supplementation.

The IoT(Internet of Things) service provides users with valuable services by collecting and analyzing data using Internet-connected IoT devices. Currently, IoT service platforms are accomplished by using edge computing to reduce the delay time required to collect data from IoT devices. However, if a user moves to another network with IoT device, the connection will be lost and IoT service will be suspended. To solve this problem, we proposes a service that automatically roaming IoT service when IoT device makes move. IoT roaming service provides a device automatic tracking management technique designed to continue receiving IoT services even if users move to other networks. To check if the proposed roaming service was effective, we implemented IoT roaming service and measured the data transfer time while move between networks along with devices while using IoT service. As a result, the average data transfer time was 124.62ms, and the average service interrupt time was 812.12ms. with this result, we can assume that the user could feel service interruption time very shortly and it will not affect the service experience. with IoT roaming service, we expect that it will present a method that stably providing IoT services even if user moves networks.

This study suggests a general formula of non-cohesive sediment transport rates for waves and currents which is also valid for wave only or current only condition. On-offshore sediment transport rates with the second order Stokes wave in the shallow water are calculated as the pickup rate times the distance. The formula depicts reasonably that high waves move material offshore, and low waves move material onshore. Also the formula, as is the case the waves with long period tend to move material onshore, shows good results.

This study shows that frequency of tropical cyclone (TC) around Korea in summer (June-September) has positive relation with Arctic Oscillation (AO) in the preceding April. In a positive AO phase, each of anomalous cyclone and anomalous anticyclone is developed in low latitude and middle latitude regions of East Asia from the preceding April to summer. As a result, while anomalous southeasterly around Korea serves as a steering flow that TCs move toward this area is strengthened, northwesterly that reinforced in southeastern area of East Asia plays a role in preventing TCs from moving toward this area. In addition, due to this distribution of pressure systems developed in this AO phase, TCs tend to occur, move and recurve in further northeastern region in the western North Pacific than TCs in a negative AO phase. On the contrary, TCs in a negative AO phase mainly move westward toward southern China or Indochina Peninsula from Philippines. Eventually, intensity of TCs is weaker than those in a positive AO phase due to the terrain effect caused by high passage frequency of TCs in mainland China.

The purpose of this study was to examine the effects of sociotropy, as perceived by college students, and ambivalence over emotional expressiveness on their interpersonal problems. A total of 248 college students (127 males and 121 females) living in Seoul and Gyonggi responded to questionnaires, which included items related to sociotropy, ambivalence over emotional expressiveness, and interpersonal problem. First, college students' sociotropy was correlated with ambivalence over emotional expressiveness and interpersonal problems. It was suggested that people with high level of sociotropy experienced more emotional expressive conflict and interpersonal problems than people with low level of sociotropy. Second, male and female college students' ambivalence over emotional expressiveness partially mediated the relation between sociotropy and move toward other people, one of the interpersonal problem's subtypes. Male college students' ambivalence over emotional expressiveness has fully mediated the relation between sociotropy and move against other people, one of the interpersonal problem's subtypes. And female college students' ambivalence over emotional expressiveness has fully mediated the relation between sociotropy and move away from other people, one of the interpersonal problem's subtypes. According to gender difference, different interpersonal problems appeared. This study's results may provide some important suggestions for interpersonal problems in college students by increasing understanding of multiple dimensions according to their internal tendency and emotional expressiveness.

${\Delta}-moves$ are closely related with a Vassiliev invariant of degree 2. For classical knots, M. Okada showed that the second coefficients of the Conway polynomials of two knots differ by 1 if the two knots are related by a single ${\Delta}-move$. The first author extended the Okada's result for virtual knots by using a Vassiliev invariant of virtual knots of type 2 which is induced from the Kauffman polynomial of a virtual knot. The arrow polynomial is a generalization of the Kauffman polynomial. We will generalize this result by using Vassiliev invariants of type 2 induced from the arrow polynomial of a virtual knot and give a lower bound for the number of ${\Delta}-moves$ transforming $K_1$ to $K_2$ if two virtual knots $K_1$ and $K_2$ are related by a finite sequence of ${\Delta}-moves$.
