경관평가에 있어서 선행되어져야 할 기본적이면서도 중요한 과정이 바로 조망점의 선정이다. 그러나 현재까지도 조망점의 선정방식은 정확한 지표나 근거없이 평가자의 주관적이고 인위적인 방식에 의해 선정되어 왔다. 따라서 본 연구에서는 GIS와 공간구문론을 이용하여 보다 객관적이고 정량화된 조망점 선정 방식을 제시하고자 하였다. 이를 위해 대구광역시에 위치한 삼덕3주거 개선지구를 대상으로 거리 및 방위에 의해 24개의 섹터로 가시권 범위를 분절하였다. 그 후, 공간구문론의 축선도 분석과 가시빈도 분석을 실시하여 공간적으로 균등하게 분포하는 후보조망점을 선정하였다. 조망점 가치판단지수를 통해 최종적인 조망점을 선정한 결과, 근경인 VP-2 조망점의 VEI값은 112.63, 중경인 VP-10 조망점은 18.31, 원경인 VP-18 조망점은 5.55로 분석되었으며, 모두 국채보상로 상에 위치하고 있었다. 선정된 조망점은 공공기관, 공원, 고밀도 주거공간 등과 같이 인구유동량이 많아 조망기회가 높고, 동시에 경관변화율이 큰 지점인 것으로 확인되었다. 이와 같이 조망점 가치판단지수는 조망점을 정량적으로 선정할 수 있는 객관적인 지표로서 활용될 수 있을 것으로 판단된다.

Interior noise, engine speed and vehicle speed are measured under transient road-load condition and interior noise signal is transformed by using the transient signal analysis methods, such as the spectrogram and wavelet transform. Using the analyzed results, subjective noise metrics such as the loudness, sharpness and articulation index at each vehicle speed can be estimated and characteristics of interior noise for various running modes can be discussed in the viewpoint of noise quality.

Development of index for evaluation of environmental nature and its application for the purpose of construction of industrial complex with environmentally friendly. Industrial complex comes to be recognized as a disgusting zone according to the increasing environment consciousness of residents. And the objection about the exploitation of geographically unwanted land site is increased during development process and it is possible to cause Nimby phenomenon. Therefore, ecology and environment-oriented strategies tends to be adopted for industrial complex development. Furthermore, the maximization of profit mainly directed by enterprises as of today cannot guarantee its future and the efforts of adopting environmental constancy and harmony as a new objective are made progressively. For the development of city and region, in particular such as residence complex, farming and special city, the discussion of environmental consistency, new paradigm with environmentally friendly is briskly under progress, but the relevant discussion for the development of industrial estate is not done so much. Just only few studies are realized from the viewpoint of industrial ecology but its level remains in the understanding of the concepts and presentation of development direction. This study is to prepare for the foundation of the construction of industrial estate with environmentally friendly under the current condition of Korea against coming future environment era and to try to develop of evaluation range and index which are the basis of evaluation of environment. I applied the above evaluation index to the residents of actual industrial estate to understand their consciousness of decreased environment. And I obtained 7 evaluation ranges and 37 evaluation indexes for the relevant residents. Among them, I get the value less than the average in 19 index items. And they represent very sensible reaction about environment pollution including decrease of waste materials. This study has several limits but is meaningful in that the development of evaluation index for environmental nature in industrial complex is done, and that the basic discussion of the plan and design for environmentally friendly industrial estate is made under the above evaluation and that 37 evaluation items are applied to the reality.

이 연구에서는 기존의 h-지수와 g-지수에 대해 달리 해석해보고 새로운 Hirsch 유형 복합 지표인 전치 g-지수를 제안하고자 한다. 새로운 해석에 따라서 h-지수 및 g-지수 산출 그래프의 가로축이 인용빈도 기준값에 해당하고 세로축이 논문 수가 되도록 축을 전치하고, 이로부터 새로운 전치 g-지수를 제안하였다. 한국학술지인용색인 KCI의 문헌정보학 분야 연구자들을 대상으로 적용해본 결과, 제안된 새 지수는 h-지수 및 g-지수에 비해서 변별력이 높으며 연구의 질보다 연구의 양 차이에 더 민감한 것으로 나타났다. 연구를 지속하는 꾸준한 연구자를 그렇지 못한 연구자와 변별해주는 차별화된 특성을 가지고 있으므로 전치 g-지수는 다면적인 연구 성과 평가에 도움이 될 것으로 기대된다.

OBJECTIVES : This study develops an evaluation method, which is useful to inspect pavement condition of specific boroughs. This is because pavement condition is broadly divided into five grades via visual inspection, which does not consider the types of deteriorations, and is decided by an investigator having a subjective viewpoint. This visual inspection method is not a satisfactory method for accurate maintenance when various deteriorations occur. METHODS : The performance model considers several factors such as crack, rutting, and IRI. This method is also modified from borough SPI based on SPI (Seoul Pavement Index). Considering limited budget of borough, PI (prediction index) is suggested, which is related to the grade of pavement condition evaluation and type of materials. Practical correlation review is also conducted with statistical verification by using the Monte Carlo simulation. RESULTS : The results of the study show that modified criteria are reasonable. First, the comparison between the visual inspection result and the SPI result indicates that the R-square value is sufficiently high. Second, through the common section, each evaluation method could be compared, and the result shows considerable similarity, which increases when the range is modified. Finally, PI for predicting remaining life and the random number SPI have common parts, which means that each indicator would be adequate to be used as an evaluation method. CONCLUSIONS : Comparison and analysis results show that the developed evaluation method is reasonable for specific boroughs where financial support is inadequate for the evaluation process by using the newer equipment. Moreover, for more accurate evaluation method, previous visual inspection data should be utilized, and the database of inspection equipment have to be collected.

This study is intended to evaluate the value of functional aspect from the viewpoint of habitat. The indicators that are used in biotope evaluations are various, but most of them use the criteria to evaluate the naturality. This evaluation method cannot appropriately reflect the functional characteristics coming from relation to the surrounding biotope. In this study, the connectivity, cohesion and diversity between individual biotope are quantitatively measured by a landscape index. It is hard to draw the functional value of individual biotopes because the landscape index related to connectivity, cohesion and diversity comes from a landscape having a number of biotopes. The concept of contribution was used to overcome this limitation. The concept of contribution is to quantify how much each individual biotope contributes to the connectivity, cohesion, and diversity in a certain range of landscape by deriving the amount of change in the landscape index according to the presence or absence of each individual biotope. In order to understand the characteristics of evaluation results in functional aspect, this research has done a comparative analysis of the previous research findings in the same target area. According to the result of the research, individual biotopes such as artificial forests, fragmented natural forests, and small planting sites were highly rated.

'학과 홈페이지는 학과의 얼굴이다'고 할 수 있을 정도로 학과 홈페이지는 학과에 대한 많은 정보들을 포함하고 있다. 그렇기 때문에 학과 홈페이지의 역할은 재학생들에게 뿐만 아니라 신입생에게도 중요하다고 할 수 있다. 이러한 이유로 D대학교에서는 대학 신입생 유치 방안의 일환으로 모든 학과의 홈페이지를 평가함으로써 학과로 하여금 홈페이지의 구성, 디자인, 그리고 콘텐츠에 신경을 쓰도록 독려하고 있다. 그런데 D대학교에서 실시하고 있는 학과 홈페이지의 평가는 객관적이지 못하다는 단점이 있다. 따라서 본 연구에서는 D대학교의 학과 평가에 대한 단점을 보완하여 학과 홈페이지를 보다 객관적으로 평가할 수 있는 평가지표를 제안한다. 본 연구의 목적은 D대학교의 학과 평가에 대한 객관적인 평가가 이루어 질 수 있도록 하는 것뿐만 아니라 다른 대학교에서도 본 연구에서 제안하는 방법을 수용하는 경우 대학입시의 신입생 유치에 대한 참고자료로 활용할 수 있도록 하는데 있다.

When a ship is course-keeping in the open seas, autopilot system is adapted. The design of autopilot system is very important for improvement of ship′s element research. Automatic steering system consists of autopilot device, power unit, steering gear, magnetic or gyro compass and ship dynamics. In order to evaluate automatic steering system of ships in open seas. we need to know the characteristics of each component of the system, and also to know the characteristics of disturbance to ship dynamics. In this paper, I provide evaluation method of autopilot navigation system of the fishing ship. Prediction method based on the principle of linear superposition is introduced for irregular disturbance. For the evaluation of automatic steering system of a ship, "performance index" is introduced from the viewpoint of energy saving and calculation method is frequency response analysis. Finally, I carried out calculation of sensitivity of control constants of autopilot with various conditions of ocean environments.
