"삼국사기(三國史記)", "삼국유사(三國遺事)"에 의하면 신라 눌지왕대 박제상(朴堤上)(?-418)은 삼국의 복잡한 국제관계 속에서 영웅적인 충성을 다한 인물로 전해지고 있다. 두 사서에 전하는 내용의 연대나 사건 전개 등 다소 차이가 보이고 있기는 하지만 줄거리는 대동소이하다. 본 논문은 박제상에 대한 기왕의 연구 성과를 바탕으로 신라 눌지왕대 활약한 박제상의 정체성을 확립하기 위한 방안으로 그의 정치적 위상의 변화에 초점을 맞추어 검토해 보았다. 즉 박제상의 정체성 확립과 관련해 삽량주간(?良州干)에서 개인적인 역량으로 중앙정치무대에 등장하는 과정과 삼국의 복잡한 국제무대에서 외교적 역량을 발휘한 외교가로서의 탁월한 면모에 대해 주목하였다. 신라 눌지왕대에 활약한 박제상에 관한 문제들을 검토한 결과, 삽량주간이라는 그의 직책에서 보는 것처럼 박제상은 오늘날 양산 지방에 세력근거를 가지고 있던 인물이라고 생각된다. 다만 재지세력가였던 박제상은 왕제귀환이라는 임무를 맡게 되면서 왕경인 경주로 올라가게 되었고, 이를 계기로 경위인 나마(奈麻)를 받는 등 중앙귀족으로 편입될 수 있었다고 보았다. 그리고 박제상이 왕제를 구출하고 왜에서 장렬히 죽음을 맞이한 것과 관련하여 눌지왕은 박제상의 죽음을 통치 이념이라는 측면에서 활용하고자 하였던 것이다. 결론적으로 우리는 신라 눌지왕대 활약했던 박제상에 대한 몇가지 검토를 통하여 신라사에 있어 삽량지방이 차지하는 전략적인 위치와 함께 삽량지역의 지방세력가가 왕경의 진골신분으로까지 그 위상이 격상되는 과정을 살펴 볼 수 있었다고 하겠다. 또한 신라가 중앙집권적 국가로 성장해 나가는 과정에서 한 지역사회의 모습을 찾아 볼 수 있었다는 데에 나름대로의 의미를 찾아 볼 수 있었다고 생각된다.

Enhancing the electrical conductivity of the ultrathin organic films using Langmuir-Blodget technique is important step for the developement of molecular electronic device. The Octadecylviologen-TCNQ was synthesized with Octadecylviologen-Bromide an Lithium TCNQ Sine Octadecylviologen-TCNQ has two TCNQ snion radicals, the conductivity of LB film is expected to increase. The $\pi$-A isotherm showed that the limiting area was 150${\AA}$$\^$2/ molecule and the silid-like transition surface pressure was 25 mN/m. The electronic transition of the TNCNQ anion radical was observed at 400 nm. Intermolecular charge transfer absorption was observed at 600nm and 850~1050 nm which ay resulted from the TCNQ anion radical dimer formation. The electrical conductivity of the viologen -TCNQ LB film was 10$\^$-6/cm This values was 100 times higher than that of the quinolinium-TCNQ and pyridinium-TCNQ LB films.

The optical and the electrical properties of octadecylviologen-(TCNQ$\^$-/)$_2$LB(Langmuir-Blodgett) films have been studied. The films were made at 25mN/m with Y-type formation using kuhn type apparatus. According to a study of UV/visible absorption spectra, DS C, ESR, and I-V characteristics depending on temperatures, there is an internal change in OV-(TCNQ$\^$-/)$_2$ LB films near 350K. We have observed a status of Langmuir films using Brewster angle microscope at room temperature.

The chromosome of Anodota woodiana in the Lake Uiam was analysed as using air drying technique of spermatogonial tissue to obtain mitotic and meiotic chromosomes. The chromosome chcle did mot differ, in general, from that found in other bivalves. Chromosome of this species consisted of metacentrics and submetacentrics. The longest chromosome was 2.1 ${\mu}{\textrm}{m}$ and the shortest was about 1.4 ${\mu}{\textrm}{m}$ in length.

The purpose of this study is to determine whether movement strategies affect functional forward reach distance in a standing position. Forty-seven healthy subjects were selected for this study: 23 men and 24 women, with an average age of 22.3. Functional forward reach distances were measured as hip strategy and squat strategy (included knee and ankle movement strategy) in a standing position, respectively. The mean values of functional forward reach distance in hip strategy, squat strategy were 33.57 cm, 29.48 cm, respectively. There was significantly difference in functional forward reach distance between hip strategy and squat strategy(p<.001). There was no difference of functional forward reach distance between male and female in hip strategy, but there was significant difference in other strategy(p<.05). These results suggest that movement strategies should be considered during functional forward reach test in standing. Further study is required to determine whether movement strategies affect functional reach distance in elderly and disabled groups.

Langmuir-Blodgett technique offers a convenient and elegant way to organic conducting systems for ultra thin films. In conducting systems based on LB films, TCNQ derivatives have been extensively studied as electron acceptor molecules in a large number of organic conducting systems.[1] A very interesting UV-visible spectra of octadecylviologen-$(TCNQ^-)_2$ was obtained from a methylenechloride and acetonitrile mixture, and from Langmuir-Blodgett films. The ESR characteristics of octadecylviologen-$(TCNQ^-)_2$ were studied to understand conducting mechanism and structure of LB films. The ESR spectra infer that the N-dococylquinolinium-TCNQ LB films has anisotropic property. But octadecylviologen-$(TCNQ^-)_2$ does not show angular dependence. As the temperature increases from 350K to 450K, the ESR signal of LB films becomes sharp. Scanning calorimetry(DSC) of octadecylviologen-$(TCNQ^-)_2$ provides the endothermic reaction temperature of the films, 340K, which corresponds to the temperature, 365K, of the new ESR signal.

The purpose of this study was to investigate whether the standing balance could be influenced by the different foot positions. Seventeen patients with hemiplegia were tested for the static and dynamic balance under the different foot positions. In the balance test, subject stood by bearing weight on one foot, and the other foot was positioned in three different positions (symmetric, $45^{\circ}$ anterolateral, and anterior position). This study used the Kinesthetic ability trainer (KAT2000) to measure the standing balance. The results were as follows: 1) There were significant differences in the static standing balance in different foot positions with both weight-bearing on the paretic limb and on the nonparetic limb (p<.05). 2) There were also significant differences in the dynamic standing balance in different foot positions with both weight-bearing on the paretic limb and on the nonparetic limb (p<.05). 3) There was a significant difference when the paretic weight-bearing and the nonparetic weight-bearing were compared (p<.01). 4) when the paretic weight-bearing and the nonparetic weight-bearing were compared, anterior foot position showed a significant difference in the dynamic standing balance (p<.05), but $45^{\circ}$ anterolateral foot position did not show a significant difference (p>.05). In this study, the standing balance showed a significant difference according to different foot positions in hemiparetic patients, and standing balance was better when they stood by bearing weight on the nonparetic limb. These results indicate that it is a necessary to consider both weight-bearing limb and foot position not only in the rehabilitation program but also in achieving the stability in the independent life.

선석배정문제는 항만운영 및 관리의 첫단계이며, 각 항만의 지리적, 자연적 특성에 따라 매우 독특하면서 복잡한 성향을 띠고 있다. 특히, 인천항은 그 지리적 특성상 갑문이라는 특수한 시스템과 많은 종류의 화물을 취급하기 때문에 만성적인 체선·체화 현상을 보이고 있으며 많은 물류비의 상승 등 경쟁력을 상실하고 있는 실정이다. 본 연구에서는 인천항의 갑문이용과 선석의 배정문제에 있어서 실제 인천항을 운영하는 전문가 집단의 지식을 규칙화하고, 실제자료를 토대로 갑문의 영향을 분석하여 보다 효율적으로 운영할 수 있는 시스템과 예기치 못한 상황에 대한 대처를 원활히 할 수 있는 선석운영 의사결정지원시스템을 구축하였다. 특히 본 연구에서는 기존 연구에서 고려하지 못한 갑문을 중심으로 교차제한사항과 선석운영의 효율을 높일 수 있는 이안을 예상한 입항선박을 고려하였으며, 더 나아가 사용자로 하여금 쉽고 빠르게 선석을 운용할 수 있도록 개선된 그래픽 사용자 인터페이스(Graphic user Interface)를 갖는 대화식 접근법(User interactive approach)체제의 실시간 선석운영 의사결정지원시스템을 개발하였다.

As the need for predicting the flood stage of river from torrential downpouring caused by climate change is increasingly emphasized, the study, centered on the area of Gangwon-do Inje-gun and Jeongseon-gun of local river, is to develop peak water level regression equation by rainfall. Through the correlation between rainfall and peak water level, it is confirmed that rainfall according to duration and peak water level have a high correlation coefficient. Based on this, a relational expression of rainfall and peak water level is verified and then the adequacy of the calculated expression is analyzed and the result shows that a very accurate prediction is not easy to achieve but a rough prediction of the change of water level at each point is possible.
