This study aims to identify the influential relationship between the characteristics of tourism information of the MZ generation's SNS content, tourist destination reputation, and intentions of traveling behavior with a focus on Jeju Province. To achieve the purpose of this research, this study was conducted on 270 tourists who had recently traveled to Jeju Island after being exposed to characteristic tourism information on SNS within the last year among the MZ generation through a commissioned survey company. A total of 270 results were collected and used for empirical analysis. The results of the research are as follows. First, it was found that the reliability, usefulness, timeliness, and interactivity factors of SNS tourism information had a significantly positive (+) effect on the reputation of the tourist destination. Second, it was found that the reliability, usefulness, timeliness, and interactivity factors of SNS tourism information had a significantly positive (+) effect on the intentions of traveling behavior. Third, it was found that the tourist destination reputation has a positive (+) effect on the intentions of traveling behavior. This study discussed the future tourist destination reputation formation and future behavioral decision process of the MZ generation tourists who are constantly seeking tourist destinations. In addition, the theoretical implications presented in this study were discussed.

As the preceding research for the design of gangway in the next generation high speed train, the aero-acoustic noise at the gangway is calculated. For this purpose, the shape of gangway with mud flaps is assumed as the two-dimensional cavity. Then, 5 gap sizes between mud flaps of gangway are selected and parametric study is performed according to the gap sizes. From this study, the aerodynamic features such as vortex shedding, pressure, etc. are computed. Also, the aero-acoustic properties of tonal noise and overall noise are analyzed at the 3 locations of microphone and the relation between the gap size of mud flap and the noise level is assessed. Through this study, it is shown that the noise characteristics of base and specific models are better than those of other models.

Expending on a life course perspective, this study explores the long-term and short-term reciprocity in parent-child relationships in Korean context. Since the reasons for providing filial support are believed to differ by gender, we focused on how a child's gender affects both types of reciprocity. Data were collected from middle-aged sons (N=726) and daughters (N=883) with at least one surviving parent. Logistic regression was then conducted in order to examine the relations between the support a child currently provides to parents and the current or previous support received from the parents. Dependent variables are financial and instrumental support that middle-aged child currently provide to the parents. The financial and instrumental support a child received from the parents within a year are included in the model as an independent variable to assess short-term reciprocity. The level of financial support a child has received during the transition to adulthood process is included in the model as a independent variable to explore long-term reciprocity. Result supports the existence of gender differences in the long-term reciprocity. Daughters provided instrumental support in response to the financial support that they had received from parents during the transition to adulthood process. However, for sons, this tendency was not found. When it comes to financial support, long-term reciprocity was observed neither for the sons nor for the daughters. Both sons and daughters are prone to provide financial support to the aged parents regardless of the level of financial support they had received during the transition to adulthood process. Short-term reciprocity was found both in sons and daughters. when they have been receiving a financial or an instrumental support from the aged parents within a year, they tend to provided instrumental support to the parents. This study shows that the aged parents still fulfill the reciprocal relationship to a certain degree. Secondly, we can conclude that the norm of reciprocity interplays with the norm of filial responsibility in contemporary Korea.

This study aims to understand public perceptions of aging Korean society and related factors in the context of population aging and generational difference. Data are from 1,498 individuals older than 20 who were recruited through the quota sampling technique. Results indicated that the respondents reported less then three as the number of positive aspects of aging Korean society. Among the factors related to population aging, such as knowledge about aging, perceptions about family care, anxiety about later life, and perspectives about generational conflict, anxiety about later life was shown to be negatively associated with perception of aging Korean society across age groups. Respondents 65 and older showed more positive perception about aging Korean society and this association was conditioned by perspectives about generational conflict. Perspectives about generational conflict revealed positive associations with perception of aging Korean society among respondents aged 20-44 and 45-64, while no association was found among those 65 and older. Discussions focused on ways to alter perceptions of aging Korean society and needs for future research on this topic.

This study examines the relationship between intergenerational financial resource transfers and preparation for later life among the middle-aged. The study sample consists of 1536 middle-aged individuals with at least one living parent and one married child. The level of preparation for later life is dependent upon the level of household economic status. The statistically significant variables predicting the level of preparation for later life include age, education, subjective health status, household income and household assets. Moreover, intergenerational resource transfers are statistically significant factors that explain the level of preparation for later life. The effect of financial transfers from middle-aged parents to their adult children on the level of preparation for later life is the most significant financial transfer variable.

국내 IT시장에서 비디오 분야가 차지하는 분야는 매우 크다. 스마트폰, 테블릿 PC, 3D, UHDTV 등 간접적으로나 직접적으로 비디오 분야와 밀접한 관계를 맺고 있다. 이런 추세에 따라서 멀티미디어를 무선 인터넷 환경에서 실시간으로 감상하기 위해 비디오 분야에서는 높은 압축률의 코덱이 선결 과제이다. 이에 따라 기존의 H.264에서 좀 더 발전한 HEVC 차세대 비디오 코덱의 표준화가 진행 중이다. 이에 본 논문은 비디오 분야에서 가장 큰 복잡도를 갖는 움직임 추정 부분과 관련해서 새로운 알고리즘을 제안한다. 제안하는 알고리즘을 사용해 복잡도를 줄이고 기존 알고리즘과 비교해 화질 열화를 개선함으로써 차세대 코덱에 필요한 데이터 감소에 크게 이바지 할 것으로 보인다.

일반적으로 S자 형태의 누적수요곡선을 따르는 단일 신상품과는 달리 다세대 신상품은 세대간의 진화.대체과정에 의하여 다른 형태의 성장곡선을 따른다. Norton & Bass(87)에 의해 개발된 다세대 확산모형은 단일 신상품만을 주로 다루어온 기존의 확산이론을 확장하여 상품들간의 연관관계를 고려한 모형화를 시도하였다는 점에서 큰의의를 지니고 있다. 그러나 Norton & Bass 모형은 누적수요가 감소하는 경우에만 적용 가능한 모형으로 그들이 논문에서 분석한 전세계 반도체 시장의 경우에는 적용될 수 없는 모형이다. 그들은 신규수요를 누적수요모형에 잘못 적용하는 오류를 범하고 있다. 그들이 제안한 모형은 서비스 상품들의 대체를 설명할 수 있는 모형으로 국한된다. 본 연구에서는 재화재의 경우에 적용 가능한 모형을 개발하며 또한 개발된 모형을 Norton & Bass가 잘못 적용했던 전세계 DRAM 시장에 응용한다.

The purpose of this study is to investigate the intergenerational transmission of the family violence. The focus of the study is on the effect of the parental violent behavior on the child's aggression. For this purpose, 266 6th grade children in Seoul are classified into the two groups according to their aggression rated by their teachers. The results are as follow: 1. There are social class differences in the level of the child's aggression, experience of parent-to-child violence and parental marital violence. 2. Experiencing parent-to-child violence and parental marital violence greately affected the level of the child's aggression. The effects are greater for the children who observed parental marital violence than who experienced child violence. 3. Father-to-mother violence rather than mother-to-father violence affected the level of the child's aggression, especially for the boys.

The purpose of this study was to analyze the effects of digital literacy and the frequency of contact with children or grandchildren via ICT on cognitive functions of 8,942 adults over age 65 who responded to the 2017 National Survey of Older Koreans, using multiple regression analysis. We found that digital literacy was the most significant factor on cognitive functions of the elderly. Also, the frequency of contact with grandchildren via ICT was a positive factor for cognitive function and had a positive correlation with digital literacy. Based on this results, the importance of digital literacy education and intergenerational communication via ICT were discussed.
