The purpose of this study was to investigate the structural relationship between leisure function, resilience and life satisfaction among elderly individuals participating in leisure sports. To achieve this, data were collected from 220 elderly participants involved in indoor and outdoor sports activities in Jeonbuk Province and Seoul. In this study, frequency analysis, descriptive statistics, reliability analysis, confirmatory factor analysis, correlation analysis, and structural equation modeling were executed using SPSS 18.0 and AMOS 18.0. The results of the study are as follows. First, Leisure function positively affected resilience. Second, Resilience positively affected life satisfaction. Third, Leisure function positively affected life satisfaction. Fourth, Resilience mediated the relationship between leisure function and life satisfaction. Considering these results, it is significant that efforts have been made to seek ways to lead a healthy and happy life in old age.

통신서비스 시장은 유무선 및 통신과 방송서비스의 컨버전스화가 진행됨에 따라 미래 시장에서의 경쟁구도에 관심이 집중되고 있다 최근 영국, 이탈리아 등 유립을 중심으로 지배적 사업자의 병목설비에 대한조직분리의 일환으로 기능분리가 활발하게 논의 및 도입되고 있다. 이 중 이탈리아는 TI에 대한 운영분리 수준의 구조규제를 기능분리 수준으로 강화하였다. 이는 운영분리와 같은 구조적인 조치에도 불구하고 TI의 지배력 유지, 경쟁 사업자들의 지속적 불만 제기 등의 문제가 해결되지 않은데다가 TI의 소유구조 변화에 따른 네트워크의 안정성 및 보안성에 대한 우려에 따른 것으로 해석되고 있다. 이탈리아의 기능분리는 동등접속을 위한 사업부로 Open Access의 설립, 신규 인센티브 제도, 각종 투명성 확보장치, 감독기관의 신설 등의 내용이 포함되어 있으며 근본적인 원칙은 영국의 경우와 유사하다. TI는 기능분리를 통해 규제기관과의 관계 개선, 소매시장 규제완화 등의 효과를 기대하고 있으며 2008년 2월 Open Access를 출범하였다.

BcN에서의 멀티캐스트 특히 IPTV 방송서비스의 서비스 및 네트워크의 요구 사항을 살펴보고 기능 구조를 도출하였다. 방송서비스의 수익은 시청률에 민감하다. 특히 접속제어를 바탕으로 하는 BcN에서 IPTV 방송서비스를 제공한다면, 표본추출 방식의 기존 방송과 달리 시청자의 거동을 전수 조사할 수 있어 수익과 시청률의 관계는 더욱 밀착될 것이다. 품질 문제로 시청자를 잃지 않기 위해서는 전달망은 패킷의 손실을 최대한 막아야 하며, 네트워크 장애 발생시 서비스의 장애가 최소한으로 억제되도록 설계되어야 한다. 따라서 망은 OAM 기능 및 경로 보호 기능을 가져야 하며, 악의적인 사용자의 공격에 대한 대비책도 갖추어야 한다. 본 고에서 논의한 기능 구조에서는 서비스 인증 후 개별 채널 변환을 L2 스위치에서 접속제어하여 적법하지 않은 사용자의 접근을 막도록 하였으며, 코어 네트워크에서는 Multicast MPLS를 사용하여 OAM 및 경로보호를 제공할 수 있도록 하였다. 또한 채널 변환에 대한 정보를 파악함으로써, 자원의 사용 및 개별 사용자의 거동을 파악할 수 있도록 하였다.

The web-based multimedia development tool was implemented to create and edit multimedia contents under the graphic user interface environment with icons. The development process enables the developers to verify the contents being developed by checking for errors, exchanging feedbacks and utilizing the pre-execution feature. By applying the tree structure to the internal data format, the tool uses inherent display features among media objects with time and spatial relations to efficiently process the synchronism of media objects that participate in the presentation and asynchronism according to user interaction.

The purpose of the study is 1) to investigate the reciprocal relationship between cognitive functioning and depressive symptoms and 2) to examine whether there is gender difference in this mutual relationship. The uniqueness of the current study is in its investigation on the simultaneous reciprocal relationship between cognitive functioning and depressive symptoms, which is different from previous studies examining unidirectional relationship. Subjects were 3,511 individuals aged 65 and over who participated in the first and second wave of Korean Longitudinal Study of Ageing. Non-recursive structural equation modeling identified the reciprocal relationship between cognitive functioning and depressive symptoms, with poorer cognitive functioning leading to higher depressive symptoms and higher depressive symptoms resulting in poorer cognitive functioning. Multi-group analysis showed the gender difference in the relationship between cognitive functioning and depressive symptoms. Specifically, cognitive functioning was the significant predictor of depressive symptoms for females, whereas the depressive symptoms was the significant predictor of cognitive functioning for males. These findings indicate that the reciprocal relationship and gender difference should be considered when we development practice implications for prevention and treatment related to depression and cognitive functioning. Based on these findings, implications for theory and practice were discussed.

Objective : This study aimed to examine the association between the structural and functional aspects of social networks and health-promoting behaviors in community-dwelling older adults. Methods : Social networks based on structural and functional aspects and health-promoting behaviors by lifestyle were measured in 226 community-dwelling adults aged 65 years and over. To analyze the collected data, an independent t-test, one-way ANOVA, Pearson's correlation analysis, and hierarchical regression were performed. Results : The network size was the highest in the friend network, and the frequency of contact and social support was the highest in the non-living family network. Health-promoting behaviors were highest for activities of daily living and lowest for productive and social activities. All subfactors of social networks showed significant positive correlations with health-promoting behaviors. Hierarchical regression showed social support from neighbors as the variable with a significant effect on health-promoting behaviors; gender and depression were also influencing factors, and this model showed 37% explanatory power. Conclusion : To promote healthy behaviors of older adultsin the community, the development of health promotion programs and related policies considering social networks centering on social support from neighbors is required.

최근 수산자원의 이용, 관리 및 환경보전 등의 문제를 생태계 보존이라는 관점에서 해석하고 풀려고 하는 시도가 활발히 이루어지고 있다. 따라서 단위 생태계의 구조와 기능을 이해하고 밝히는 것이 주요한 연구과제로 대두하고 있다. 특히, 생태계의 하부 영양구조인 영양염-식물플랑크톤-동물플랑크톤의 상호관계를 밝히는 것은 어류 등과 같은 상부 영양구조의 변동을 파악, 예측하는데 있어 매우 중요하다. 본 연구는 한국 연근해의 영양염-식물플랑크톤-동물플랑크톤의 시공간적 변동 특성과 이들의 상호관계를 논의하였다. (중략)

Objectives : The purpose of this study is to evaluate the role of structural and functional changes of the brain in the pathophysiology of schizophrenia. Methods : The authors measured the regions of interest on the magnetic resonance imaging of the brain in 20 patients with paranoid schizophrenia(15 men and 5 women) and 23 control subjects(15 men and 8 women). We also assessed the neurocognitive functions with the Wisconsin Card Sorting Test, the Benton Neuropsychological Assessment, and the Weschler IQ test-Korean version, soft neurologic signs, and psychiatric symptoms in the patient group. Results : In the patient group, all ventricles and basal ganglia including caudate nucleus and globus pallidus were significantly enlarged. Although there were no significant differences between the two groups in the values of right frontal lobe and left temporal lobe, there was a tendency of decrease in the values of right frontal lobe and left temporal lobe. There were significant positive correlations between the values of ventricles and the frequency of previous hospitalization. However, there were no significant correlations between other values of regions of interest and clinical data. The value of the right frontal lobe was significantly correlated with the score of soft neurologic signs, which is suggestive of the neurodevelopmental abnormalities. There were significant correlations between the value of frontal lobe and the scores of the various subscales of Benton Neuropsychiatric Inventory. In contrast, the value of left amygdala and putamen showed significant correlation with the score of verbal IQ on the Weschler IQ test. Structural changes of the temporal lobe areas were related with the positive and general symptom scores on PANSS, while those of the basal ganglia were related with the negative symptom scores. Conclusions : These results suggest that the structural changes of the brain in the patients with schizophrenia show the dual process, which is suggestive that the enlarged ventricle show the neurodegenerative process, while enlarged basal ganglia, and shrinked right frontal and left temporal lobe show the neurodevelopmental abnormalities. Among these changes, structural changes of the frontal lobe related with various neuropsychological deficits, while those of left temporal lobe related with language abnormality. Relative to the relation between structural changes and psychiatric symptoms, structural changes of the temporal lobe areas were related with the positive and general symptoms, while those of the basal ganglia were related with the negative symptoms.

USN과 BcN은 모두 별개의 기능적 특성을 갖는 네트워크들을 지칭하고 있지만, 그 네트워크를 이용한 서비스를 실현하기 위한 상위 기능요소 및 각 요소간의 관계를 포괄하기도 한다. 그럼에도, USN 영역에서는 BcN을 높은 성능의 장거리 전달 망으로 보는 시각이 지배적이며, BcN 영역에서는 여러 종류의 가입자망 중 하나로 USN을 인식하고 있어, 둘 간의 체계적 연동을 어렵게 하고 있다. 본 논문에서는 두 서비스 제공구조의 분석을 통하여 일반화를 수행하고, 정의된 모델에 필요 기능을 할당한 후 각 기능간의 연동방식에 관하여 논함으로써, USN과 BcN 두 영역의 컨버전스를 실현할 수 있는 서비스 구조를 제안한다.
