정보화 시대로써 정보의 가치가 높아지면서 이를 불법적으로 취득하려는 공격에 대응하고자 정보보호에 대한 이슈가 대두되고 있다. 이러한 정보보호 기술 중 공개키 기반구조의 암호시스템을 사용하는데 필요한 모든 서비스를 안전하게 제공할 수 있도록 하기위한 인프라를 Public Key Infrastructure 라고(이하 PKI) 한다. 이러한 PKI는 정부나 다수 기업의 공동 연합체에서 주도적인 역할을 수행해야 의미가 있다고 볼 수 있는데, 이미 선진 각국에서는 PKI 개발 및 구축 노력을 하고 있으며 이는 21세기 새로운 국가 경쟁력으로서의 중요성이 인식되어 있는 상태다. 결국 PKI를 통한 정보보호 문제의 해결은 한 차원 높은 전자 경제 활성화의 경쟁력을 갖는 주요 포인트라고 할 수 있겠고, 범 국가 적인 PKI의 구축은 세계화의 경제를 이끌 수 있는 전자 경제의 중요한 기반 기술로서 그 영향력이 매우 크다고 할 수 있으므로 본 논문에서는 이러한 PKI의 국내 구축현황 및 기술에 대하여 살펴본다.

This study is concerned with the economic analysis of implementing a material handling system using automated guided vehicle(AGV)s in order to improve the productivity of the production process of chinawares. Analytic hierarchy process(AHP) method for selecting the facilities of material handling systems is presented. Subsequently, as an example, a chinaware production line is analyzed for the economic analysis. The result shows that seven manpowers can be reduced. However the introduction of the new material handling system is turn out to be undesirable due to high initial cost of AGV system, Nevertheless, in the long term, automatic material handling system such as AGV system are expected to play major roles in the modern manufacturing area.

In this paper, the relationship between energy consumption in the logistics industry and economic growth of Tumen River region from 1995 to 2014 is empirically analyzed by using the EKC model theory. The results show that there is a turning point in the Kuznets curve of carbon emission in TumenRiverregion. And it has the characteristic sof "invertedU" curve, which conforms to the environmental Kuznets curve hypothesis. Meanwhile it is stil lintherisingstage. According to the analysis results, it is proposed to set up the concept of low carbon logistics, optimize the energy structure, strengthen the information construction, and establish low-carbon development mechanism and so on.

고전을 현대적으로 계승하여 재창조된 작품들은 현대시나 소설, 희곡이나 영화 장르에서 빈번하게 나타나고 있다. 필자는 '고전 시가의 현대적 계승과 변용'에 주목하면서 그렇다면 시조 장르의 경우에는 '고전의 재창조' 양상이 어떻게 이루어지고 있는지 궁금하였고 본 논의는 기본적으로 이러한 관심사에서 출발한다. 이 과정에서 고전을 현대적으로 계승하여 재창조한 시조는 상당수의 분량을 차지하고 있고 지금도 현대시조로 재창조된 작품들이 지속적으로 나타나고 있는 것을 확인할 수 있었다. 특히 1920년대 이광수의 시조를 비롯하여 1940년대 조운의 시조는 이 방면에서 선구적인 작품들이다. 이후 현대시조에서 고전을 재창조한 작품들은 지속적으로 이어지고 있다. 그렇다면 이렇게 재창조된 현대시조는 과연 어떠한 의미를 지니는 것이며 그리고 그것이 나아가야 할 방향은 무엇인지 파악하여 점검해 보는 데에 본고의 목적이 있다. 또한 이러한 논의는 현대시조 창작의 미래를 위한 단서를 제시해 줄 수도 있을 것으로 예상된다. 고전을 현대적으로 계승하여 변용하는 일련의 작업들은 전통문화를 이어 가며 고전의 당대성과 현대성을 연결시킴으로써 인간의 삶의 문제를 돌아보게 한다는 점에서 그리고 집단의 정서를 공유할 수 있게 한다는 점에서 매우 가치 있는 과제라 할 수 있다. 일례로 이광수나 조운의 시조는 고전의 재창조 작업을 통해 문학사적 의의를 지니고 있음을 확인할 수 있다. 문제는 이러한 맥을 이어받아 고전의 창조적 실험을 꾀하고 있는 현대시조에 있다. 많은 현대시조들이 시조의 구조적 원리와 형식 미학을 체득하지 못하고 내용의 기법에 치중한 상태에서 창작되고 있기 때문에 고전을 현대적으로 수용 한 시조들은 창작의 한계를 드러내고 있다. 게다가 다시 산기의 내용도 원전의 내용을 그대로 담아 시조 화하는 것은 의미가 없다. 그런 점에서 고전을 다시 살기 한 현대시조는 현재의 삶과 문화. 시대 현실을 반영하면서 시조의 형식 미학을 함께 겸비할 때 그 영역의 타당성을 확보해 낼 수 있다.

In this study, the wave power resources at the southern sea of Korea were estimated by using the hindcasted wave data of previous researches. The used data were wave heights, periods and directions which were hindcasted around the Korea peninsular from 1979 to 2003. The spatial resolution of the hindcasted data is $1/6^{\circ}$(about 18 km). In winter, the northwest monsoon increase the wave power, while the wave power around Korea peninsular is very small in spring. The maximum value of the annual mean wave power is about 13 kW/m at Gageo-do, Heuksan-do and western region of Jeju-do, while those at the southern sea of Korea is only 4 kW/m, which is relatively small. The wave power at Korean east sea is lower than that of Korean southern sea. We obtained the wave resources information, in a fine grid, at Gageo-do, Heuksan-do, and western sea of Jeju-do, by solving SWAN model with the boundary conditions of hindcasted wave data.

Purpose: Investigation of the quality of life (QoL), family support and associated variables in patients with Parkinson's disease. Methods: The data were collected from 102 patients registered in the neurology department of C University Hospital. QoL was assessed using the Parkinson's Disease Questionnaire (PDQ-39) and Family Support Scale. Modified Hoehn and Yahr (H & Y) stages were obtained from an interview and clinical examination by a neurologist. Collected data were analyzed using the SAS program. Results: The participants' PDQ-39 average score was 34.34. The scores were significantly higher for participants who were older, who had a job and who were over 2.5 on the H & Y stage. The average for Family support scores was 41.6. Participants who had a living spouse, religion and a job scored higher than those who did not. PDQ-39 score had a positive correlation with age, job, and H & Y stage. Family support and PDQ-39 score were also positively correlated. Conclusion: It is recommended a program involving family that improves family support and be developed and that it be varied according to different H & Y stages, in order to improve QoL.

Objectives : This study analyzed the differences in length of stay(LoS), total hospital charges(THC), and cost of rehabilitation(CoR) between two types of stroke patients, intracerebral hemorrhage(ICH) and cerebral infarction(CI). Factors associated with these differences were also assessed. Methods : Data were obtained from the 2011 National Inpatient Sample data of Health Insurance Review and Assessment Service. We used propensity score matching to match the characteristics of the two types of stroke patients, and conducted a regression analysis to analyze their associations. Results : The differences between THC, LoS, and CoR by stroke and hospital types were shown. Each type of hospital showed different results. Conclusions : A rapidly aging population will accelerate the number of stroke patients requiring effective management. Studies evaluating healthcare utilization of stroke patients will provide evidence for both healthcare resources allocation and healthcare policy decisions.

Objectives : Obesity is a worldwide health concern due to an increasing obese population. This study proposed to analyze the differences in medical costs and care utilization between obese and normal group using propensity score matching. Methods : Data were collected from the sample cohort database by the Korea National Health Insurance Corporation. Propensity score matching(PSM) was applied to control selection bias, and factors affecting obesity were used as covariates in PSM. Results : The results showed higher medical costs and care utilization in the obese group than the normal group. According to gender and medical type, there were differences in the relationships between obesity and medical charges and utilization. In particular, the differences in the female population were larger in both outpatients and inpatients than the male population. Conclusions : It is important to manage obesity, because obesity has a negative effect on national health insurance costs. These findings suggest directions for future research.

Purpose: To develop & to examine the effect of a Tailored Exercise Program (TEP) on physical fitness in patients with Parkinson's disease (PD). Method: In a two-group pre-and post-test design, from a total 41 participants. 21 were assigned th the experimental group find the remainder to the control group. The experimental group participated in a 4-day a week, 8 week program in which one session a week was by direct instruction with the self-help group and two sessions a week were by videotaped instruction at home by themselves. The control group did not receive any intervention. Results: The eight week TEP in patients with PD was found to be significantly effective in enhancing muscle strength, ankle flexibility, and balance. However instrumental activities of daily living was not changed by the intervention. Conclusion: These results suggest that TEP can have an effect on physical fitness in patients with PD. Further research with a larger sample and for a longer follow up period is needed to expand our understanding of the effects of TEP for patients with PD.
