본 연구는 액티브시니어 여가활동 참여자의 자아존중감과 노년의 삶의 행복감에 미치는 영향을 알아보는데 그 목적이 있다. 액티브시니어들이 미래를 준비하는 여가활동의 중요성이 부각되어야 할 시점에서 미래지향적인 사고방식과 생활 의식을 보유하고 있으며 기존 고령자와 경제적 가치관등의 뚜렸한 차이를 보이고 있는 액티브시니어 여가활동 참여자의 자아존중감이 미치는 영향력을 분석하는 것은 100세 시대를 준비하는 액티브시니어의 보다 만족스러운 성공적인 노화와 행복한 삶을 극대화 시킬 수 있으리라 연구의 필요성을 제기하는 바이다.

This study was performed to reveal the factors determine self-rated health status between middle aged and elderly living in community. The subjects for this study consisted of 142 middle aged and 201 elders who lived in 3 cities of convenience sampling method. The Data was collected through personal interviews with questionnaires from March to July, 2014. For the data analysis, descriptive statistics, Pearson's correlation coefficient and multiple regression were used with SPSS Statistics program. The determinants on self-rated health status were present illness, stress management, health responsibility, fatigue, anger, tension, and social support among the middle-aged persons and physical activity, present illness, confusion, and exercise among elderly persons. On the basis of the results in this study, we should develop differentiated health promotion programs through education, counselling and health examination for the middle-aged adults and elderly.

IoT 장치들은 연구, 의료, 금융, 민생 분야 등에 지원하고 있으며 취약한 보안 메커니즘으로 인하여 IoT 네트워크의 개인정보 안전성이 중요해지고 있다. 안전한 다자간 계산은 서로 믿지 않는 참여자라도 데이터 수요자에게 원본 데이터를 누설하지 않는 범위 안에서 다자간 연합 계산 능력을 제공한다. 상업 네트워크나 산업 네트워크에서는 대량의 데이터는 다른 플랫폼들과 통신하기 때문에 기업이나 개인의 개인정보 데이터가 통신 과정에서 도청될 경우 데이터 보유자에게 막대한 경제적이나 잠재적인 손실이 발생한다. 본 논문에서 데이터 통신 과정을 계층별로 정의하여 블록체인에 기반의 안전한 다자간 계산 아키텍처를 제안한다. 제안하는 이키텍처에서 블록체인을 사용함으로써 데이터의 유효성 및 검증 가능성을 보장한다. 인증된 데이터로 안전한 다자간 계산 수행하기 때문에 통신과정의 보안성 및 기밀성도 확보한다. 암호학 및 블록체인 기술의 지속적 발전 및 활성화에 따라 제안하는 아키텍처가 지속적으로 개선할 잠재력이 있다.

Objectives: It attempted to analyze influencing factors on the utilization of outpatient services which were adopted to predisposing, enabling, and need factors in Anderson model. Methods: The current study analyzed "2007 Korean National Health Nutrition Survey" data, which selected 3,335 people nationwide by proportional systematic sampling. This study analyzed data of persons who used outpatient services in two weeks. It adopted Anderson Model to control contextual factors including socioeconomic factors. The study compared means and fitted logistic regression models and multilevel model. Results: The logistic regression model showed that persons purchased private medical insurance were less likely to use outpatient services than the persons did not purchase private medical insurance. Persons with hypertension and diabetes mellitus, overweight, and problem drinkers were more likely to use outpatient services. Persons with high school graduates or higher in education level and experience of accidents or intoxications were more likely to use outpatient services according to the multilevel analysis of mixed model which treated region as random effect. Conclusion: Higher level of perceived stress increased the probability to use outpatient service than lower level of perceived stress. As number of days a person had exercised increased, the probability to use outpatient service decreased. Overweight and problem alcohol drinking increased the probability of outpatient service use. Further research should be conducted to find more factors influencing outpatient service use.

This paper attempts to explore the spatial structure of inventor networks and their determinants among 230 shi-gun-gu regions in Korea by investigating the residence of co-inventors engaged in Korean patent applications to the Korean Intellectual Office and exploiting a zero inflated negative binomial model to accommodate an estimation to the count nature of a dependent variable and its excess of zeros. Several variables are found to affect the spatial linkage of inventor networks. Spatial links extend beyond the region if it has more own R&D-related specific assets (private R&D, patent productivity, population, education); if it is physically close to and has technological similarity with the other region. The assets of the other region plays a positive role if, in a similar way, the other region has more R&D-related specific assets.

This paper is intended on providing solutions for overcoming constraints to the transmission of the Important Intangible Cultural Properties related to dance successors. For accommodating this approach, six career dancers, from the Dance Society of the Important Intangible Cultural Properties, were invited as the research participants for this study. The In-Depth Interviews and the classification analysis are used as a way of structuring and understanding my observations about these tasks. These interviews have also been verified by an expert group. In conclusion, this study identifies numerous obstacles which can restrict the transmission of the Important Intangible Cultural Properties are as follows; first, the dance successors are constrained by personal reasons such as physical strength and mutual understanding at home; second, the dance successors are affected by the structural constraint of programs such as required time for the completion of training, efficiency of the training program and the educational environment; third, the dance successors are constrained by personal relations such as the relationship between themselves, or between the dance successors and holders of Important Intangible Cultural Properties. Suggested solutions for overcoming the constraints to training programs are; building small sized training centers throughout the country; making training time realistic for individuals; and making programs to train the dancers as well as making it sociable.

The purposes of this study are to identify factors that affect personal information protection activities from the perspective of personal information managers and explore ways of promoting such activities. The main factors examined by threat and response assessments were selected based on the protection motivation theory, and the effects of each factor were analyzed using a multinomial logit model. The analysis results show that small-scale personal information managers need to be provided with both educational support to enhance their awareness and technical support, such as protection inspection tools, to help them carry out their own personal information protection activities. Personal information managers larger than a certain size also require tax support, including tax cuts, to support their budgets for and investments in personal information protection activities. In addition, they need professional education that emphasizes practice.

A Gene content phylogenetic tree and a 16s rRNA based phylogenetic tree were compared for 33 whole-genome sequenced procaryotes, neighbor joining and bootstrap methods (n=1,000). Ratio of conserved COG (clusters of orthologous groups of proteins) to orthologs revealed that they were within the range of 4.60% (Mezorhizobium loti) or 56.57% (Mycopiasma genitalium). This meant that the ratio was diverse among analyzed procaryotes and indicated the possibility of searching for useful genes. Over 20% of orthologs were independent among the same species. The gene content tree and the 16s rDNA tree showed coincidence and discordance in Archaeabacteria, Proteobacteria and Firmicutes. This might have resulted from non-conservative genes in the gene content phylogenetic tree and horizontal gene transfer. The COG based gene content tree could be regarded as a midway phylogeny based on biochemical tests and nucleotide sequences.

인터넷의 확산으로 일반인들이 높은 정보수집력을 보유하게 됨에 따라 소비자 중심의 시장이 형성되면서 전자상거래를 통한 소비자간의 거래가 점점 늘어가고 있다. 그에 따라 많은 연구자들이 소비자간 전자상거래를 지원하기 위한 지능형 에이젼트를 개발하고 있다. 그러나 기존의 소비자간 전자상거래 에이젼트 시스템은 경매나 역경매와 같은 '1:다'의 경쟁적 협상을 지원하거나, 판매자와 구매자의 거래성사를 위한 시간흐름에 따른 가격조건 완화를 이용한 자동협상에 주로 촛점을 맞추고 있다. 본 연구는 기존의 자동협상에 관한 연구와는 다른 관점에서, 소비자들간에 거래하려는 제품에 대해 제품사양 및 거래조건의 변화가 가능한 경우에 판매자와 구매자가 느끼는 개인적인 효용의 차이를 이용하여 판매자와 구매자가 모두 만족하는 제품사양, 거래조건, 가격의 거래결과를 찾아주기 위한 자동협상구조를 제시한다.
