As the aging population has increased, the silver generation is getting to account for the considerable percent of economic activities and becomes the main body of production and consumption. Although the economic activity of silver generation is increased, the development of silver contents for the leisure activities is still not revitalized. The serious silver contents and the easy-to-use interface are very important because the silver generation is relatively weaker than young people in perception, studying, and exercise, and is fragile in mobility and vitality. This paper suggests methods to develop sensory bicycle, gate ball, and mole game contents haying lower body exercise effects for the silver generation to utilize leisure and maintain health. Along with fun as games, functional design factors suitable to the cognitive ability and bodily activity ability of the silver generation were considered and through sensory intefaces that are easy for the silver generation to use and customized progressing methods complying with individual characteristics, it was attempted to induce continued interests and lower body exercise effects.

이동통신 장비 제조업체에게 있어 3세대 장비시장은 2세대 이후 10여 년 만에 맞이하는 대규모 장비시장이라는 현실적인 측면은 물론, 향후 본격적으로 형성될 3세대 단말기 시장경쟁에서 시장을 선점할 수 있다는 측면에서 전략적으로 중요한 위치를 차지한다. 본 연구에서는 현재까지 이루어진 3G 시스템 공급 시장자료를 기반으로 시장구조와 3G 장비공급 시장의 특성 파악을 통해 국내 제조업체들의 장비시장 진출의 당위성과 진출을 위한 전략수립시 도움이 될 수 있는 시사점을 제시하고자 한다.

빠르게 진화하는 상용 웹 사이트들의 검색 및 인터페이스 기술과 달리 도서관의 OPAC 시스템은 그 변화를 빨리 수용하지 못해 그 결과로 OPAC 사용에 있어 이용자들은 불편을 느끼고 있다. 이처럼 도서관 OPAC의 진보적인 개발이 시급한 실정에서 등장한 개념이 '차세대 OPAC'이다. 본 연구는 차세대 OPAC의 특성을 열거하여 핵심 항목으로 구성 된 체크리스트를 개발하고 향후 이를 이용하여 대학도서관에서의 차세대 OPAC 적용 현황을 평가 분석하는 도구로 사용하고자 하였다. 본 논문에서는 최종적인 연구의 초기단계로 차세대 OPAC에 관한 선행연구 분석을 통해 체크리스트 예비 항목을 작성하는 것으로 제한한다.

Because of a rising in the standard of living and the development of medical technology, Korea is expected to become an aging society more than 14% elderly population and the silver generation will be responsible for the large portion of economic activities. The silver generation has relatively diminished in perception, learning, and exercise due to the physical aging. Therefore, it is important the development of game contents which can constantly provide the maintenance function of physical and mental health and the functional exercise with spending the leisure time. In this paper, we suggest a design method for developing the game contents which are able to help the silver generation to strengthen their lower extremities and to enjoy their leisure time. The proposed method will enable to lead the silver generation to carry on the physical activities with the amusement of playing a game through the functional design concepts appropriate for the ability of the silver generation's perception and physical activities, an adaptive game process customized by the individual capability and a user-friendly sensory interface.

The baby boomers born between 1955 and 1974, recently called the new age, form a huge population group and show characteristics different from the previous traditional older generations. With the retirement of those who make up 33% of the nation's population in earnest, the emergence of a new generation of the elderly population and policy changes are required. The new middle age generation, also called the opal generation, want to spend their old age productively and autonomously, which has increased due to the increase in life expectancy, and have some economic ability, such as enjoying overseas travel in old age. As preparation for old age is insufficient, policy attention is required for the younger generation as a new generation. In this paper, focusing on the baby boom generation, the definition of the opal generation, their consumption lifestyle, attitudes, social activities, leisure activities, and lifestyle such as health efforts are investigated, and job creation, social re-education, and local It is intended to present practical measures for preparing for old age, such as the establishment of medical facilities and social consideration for a leisurely cultural life.

The purpose of this study was to identify the convergent influence of social awareness and health status on social support in Korean echo generation by using Korea adult psycho-social anxiety survey data. Korea adult psycho-social anxiety survey data were collected from August to September 2015 and included 1,653, who responded to the question regarding social support. The data were analyzed by t-test, chi-square and hierarchial multiple regression using SPSS WIN 23.0 program. The mean score of social support was 19.60. The influencing factors on social support were neighborhood relations, perceived class, euphoria, equality in society, stability in society, self Esteem, communication, and stress, respectively. Therefore, it is necessary to establish strategies to strengthen social support of echo generation. A more careful examination may be warranted.

마이크로셀 시스템에서 트래픽(통화량) 성능은 가입자(사용자)들의 이동성에 민감한 영향을 받는다. 셀 내 체류시간 및 채널점유시간은 이동 속도 및 방향의 추계적인 변화에 의하여 특성지어진다. 셀 내 체류시간은 채널점유시간과 같은 통화량 성능을 분석하는데 기초적으로 이용되는 중요한 정보를 제공한다. 차세대 이동통신 네크워크로 진화해 가는 과정에서 증가하는 사용자들의 접속요청을 수용하고 주파수 효용도를 높이기 위하여 셀의 크기는 매우 작아진다. 셀의 크기가 작아질수록 통화량 성능은 사용자들, 특히 보행자들의 가변적인 이동성에 더욱더 영향을 받게된다. 단순화된 모형을 이용한 기존연구는 제2세대 이동통신에서는 수용할만한 정확성을 보였으나, 통화량 분포의 변화가 시간적으로 크고, 보행자의 이동성에 영향을 많이 받는 picocell (피코셀)의 특성을 적절히 반영하지 못하여 성능분석의 정확성을 기대하기 어렵다. 보행자의 가변적인 이동성을 수리적으로 분석하기 '위하여 랜덤 웍 (random-walk)모형을 적용하여 기존의 연구보다 개선시킨 확률모형을 제안한다. 제안된 모형으로 추계적 상관관계가 있는 보행자 이동성의 가변적 특성을 분석할 수 있다. 주요 통화량 성능지표를 제안된 모형으로 분석하였다.

This study poses a question on whether the Jangmadang Generation, which has been the focus of the sociological interest, can form an actual generation by transcending the social classes, status of students, ethnicity, and gender, etc. Therefore, in this study, the author compared the consciousness of the Jangmadang Generation in terms of politics, education, society, compliance with law, and education with their preceding generations. The data used in this study were gathered from the North Korean defectors who defected within the past five years over the period from November to December 2016. A total of 200 questionnaires were used for data analysis, which was conducted using SPSS 20.0, in order to show differences between groups and perform frequency analysis. The analysis results showed that the consciousness of the Jangmadang Generation in politics, society, compliance, and education was lower, while the economic consciousness was significantly higher compared to earlier generations. As their objective generational status, the Jangmadang Generation had experienced the 'March of Ordeal' and 'Collapse of Public Education' while they were still teenagers. Such a difference in their generational status influenced the formation of different consciousness as a generation compared to the earlier generations. Compared to the earlier generations who received 'proper public education,' the Jangmadang Generation, who did not receive 'decent public education' shows a generally lower level of consciousness compared to the earlier generations. As such, the Jangmadang Generation has the potential to form a separate generation with a different generation consciousness from that of earlier generations.

One of the sapstain fungal species isolated from the stained sapwood of a Japanese black pine in Korea was characterized. The fungal species is tolerant to cycloheximide and has Petosum-like synnema and Sporothrix type synanamorph which are found in the anamorphs of the Ophiostoma piceae complex group. But the species could not form perithecia on MEA. Based on cultural and morphological properties and analysis of the $\beta$-tubulin gene sequence, the fungal species was identified as Ophiostoma quercus. Here, we report mycological characteristics of the anamorphic stage of Ophiostoma quercus isolated in Korea.
