지금까지의 애니메이션 작업은 애니메이터의 객관적 감성과 경험에 의해 이루어져 왔다. 소프트웨어 디자인에 있었어도 지성적인 데이터들을 바탕으로 제작되어져 왔다. 이는 객관화하기 용이한 자료로서 데이터화하기가 쉬웠기 때문 일 것으로 보인다. 이와는 반대로 인간의 감성은 객관화하고 디지털화하기 어려운 요소들이 많이 존재한다. 본 연구는 디지털화하기 어려운 인간의 감성적 데이터를 객관화하고 이를 정량적 데이터로 활용할 수 있는 방법에 대한 부분으로 나는(flying) 궤적(path)을 연구 대상으로 하였다. 실험에 있어 인간이 나는 제적에 대해 어떻게 표현하는지에 대한 감성어를 수집하였다. 수집한 감성어를 통해 감성 평가어를 추출하고 추출한 감성 평가어에서 느껴지는 나는 궤적에 대한 스케치 이미지를 수집하였다. 수집한 스케치 이미지를 기초로 본 연구의 핵심이 되는 실험 동영상 샘플을 제작하였다. 다음으로 나는 궤적을 나타내는 감성어에 대한 물리적 요소와 동영상 샘플과의 상관관계를 분석하기 위해 수량화이론III류와 수량화이론I류를 각각 이용하였다. 그 결과 감성어와 동영상 샘플과의 구조를 파악 할 수 있었고, 나는 궤적에 대한 감성반응의 물리적 자극요소 또한 분석 할 수 있었다. 나는 궤적은 오브젝트(object)가 지나간 경로(path)에 해당한다. 이러한 경로(궤적)를 보고 감성자극 요소들이 복합적으로 작용하여 독특한 감성어로 표현되어 지는 것으로 보인다. 여기엔 감성을 자극하는 요소들이 존재하는데, 그 요소로는 속도, 회전, 규칙 그리고 호의 길이가 그 물리적 요소인 것으로 파악되었다. 본 연구를 통해 나는 궤적의 애니메이션을 표현하는데 있어 애니메이터들의 주관적인 감성 표현들을 객관화, 정량화 시키고자 하였으며, 본 연구의 데이터는 감성 애니메이션 시스템 설계에 있어 기본 데이터로 적용되는 것을 목표로 하고 있다.

The purpose of this study was to analyze the face validity of the revised EPTA (English Proficiency Test for Aviation) to see if the tests actually contribute to the enhancement of aviation safety and achieve the purpose of the assessment. In order to reach the above objectives, 103 pilot test takers were surveyed, and nine in-depth interviewees were selected and interviewed. In addition, detailed research results were derived by dividing the participants into the pilot's flight experience (31 captain pilots, 42 first officer pilots, and 30 general commercial pilots). As a result, pilot participants were generally aware that EPTA was more reasonable because the revised EPTA properly implemented the aviation situation and gave participants motivation to learn aviation English. It was also seen that first officer pilots had a higher face validity of EPTA than captain and general commercial pilots. The reason was that first officer pilots considered air traffic control job was more important than other pilots did.

This study aimed to provide empirical evidence about expert performance approach in aviation field and the results suggested that the amount of experience(e.g. total flight hour) is necessary but not sufficient index of a pilot's expertise or superior performance. 43 pilots participated and completed a spatial span task and SA (situation awareness) tasks. To explore the factors predicting the performance in routine and non-routine situations, discriminant analysis was conducted. The results of discriminant analysis indicated that different variables are related with the performance in routine and non-routine situation. The factors predicting performance in routine situation were the spatial span scores and total flight hours. On the other hand, the factors predicting performance in non-routine situation were age and the qualification for instrument flying. In real world, total flight time which represents the quantity of experience has been frequently used to predict flight abilities and as an important index of expertise. The results of this study suggest that these kinds of factors have to be used cautiously to predict the performance in abnormal situation.

A few characteristics of membrane structures which the author thinks important for design are described on the basis of his experience in research and design of this kind of structures. Different in behaviors of air-supported and air-inflated structures are first explained for a better understanding of these structures. Attention is drawn to unfavorable behaviors of an air-beam when it is reinforced by diagonal members. The shallowest membrane structure which can be made as an airdome is pursued, and its application to a metal membrane dome is shown. Attempts which have been made by the author seeking for the possibility of membrane structures made of metal sheet, plastic film with and without reinforcement are described with realized examples. A 100m long jumbo carp is explained as an example of a flying membrane.

Traditionally aircraft had descended in steps to level at the MDA(Minimum Descent Altitude) during the conduct of non-precision approach. This "de-stabilized" method of flying an instrument approach procedure is considered as a major contributing factor in CFIT(Controlled Flight Into Terrain) accident and increasing pilot workload. In the effort to reduce CFIT accident and pilot workload, VNAV(Vertical Navigation) Approach has been suggested as means to manage the vertical component of non-precision approach procedure.[1] But In the actual circumstances in Korea, VNAV has not been using to reduce them because of many restriction facts and no published VNAV chart in particular airport. Therefore we are suggesting Constant Vertical Speed Approach Method, which is required few restriction facts, and the pilots who are using this method will experience a similar method like a Glideslope during proceeding non-precision approach. Consequently, We are expecting to reduce CFIT accidents and pilot workload.

Many military and commercial aging aircrafts flying beyond their design life may experience severe crack and corrosion damage, and thus lead to catastrophic failures. In this paper, were used in a finite element model to evaluate the effect of corrosion on the adhesive damage in bonded composite repair of aircraft structures. The damage zone theory was implemented in the finite element code in order to achieve this objective. In addition, the effect of the corrosion, on the repair efficiency. Four different patch shapes were chosen to analyze the adhesive damage: rectangular, trapezoidal, circular and elliptical. The modified damage zone theory was implemented in the FE code to evaluate the adhesive damage. The obtained results show that the adhesive damage localized on the level of corrosion and in the sides of patch, and the rectangular patch offers high safety it reduces considerably the risk of the adhesive failure.

In XXI century it is necessary to expect the recommencement and development of activities on mastering the Moon. In the long term it is construction of manned lunar bases with industrial, astrophysical, procuring, repair equipment and services. Interplanetary flights from the Moon demand smaller power expenditures, than from the Earth, therefore it is favourable to use its surface for the construction of space-vehicle launching sites. Flights of devices in libration points in the system 'Earth - Moon' are considered. Experience of engineering system creation for the Moon displays the great complexity in provision of serviceability and reliability of friction units. Open friction units should operate under following conditions on the Moon: pressure of environment (vacuum) $p\;>10\;^{-10}$ Pa; wide range of temperature change $+150^{\circ}C\;...170^{\circ}C$; high evaporability of lubricants; influence of temperature gradients and warping of constructions; sublimation of elements of constructional materials; irradiation of different physical nature; effect of micrometeorites; reduced gravitation; influence of abrasive particles of lunar ground; requirements on minimization of size and weight characteristics of a construction (high tension); undesirability (impossibility) of application of liquid and plastic lubricants; vibration, shock, acoustic loadings during start and landings to the Earth; difficulties in repair-regenerative operations in conditions of the Moon etc. Adhesive interaction of conjugated surfaces is the principal reason of possible failures of rubbed units on the Moon. In the research of the Moon automatic interplanetary stations of 'Luna' (USSR), 'Surveyer', 'Apollo' (USA) series were used. Stations executed functions of flying, landing, artificial satellites of the Moon, moon-rovers and manned spacecrafts such as 'Apollo'. The experimental- theoretical researches carried out in the sixtieth years on tribology for conditions of the Moon appeared to be rather useful to engineering of an outer space exploration and the decision of complex problems for the friction units operating in extreme conditions on the Earth. For the creation of highly loaded friction units for the long service life on the Moon it is required not only to use accumulated experience and designed technologies, but also to carry out wide scientific research.
