해상교통사고의 가장 큰 책임은 사람에게 있기에 사람이 발생시킬 수 있는 사고의 요인을 명확하게 파악하고 선별할 수 있는 대책을 마련할 필요가 있다. 특히 사고를 발생시키는 근본적인 원인은 개인 스스로도 지각하지 못하는 적성상의 결함요인에 의해 발생할 가능성이 높다. 따라서 사고의 예방을 위해 개인의 적성에 대해 명확히 개념화 하고 측정하여 관리할 필요가 있다. 본 연구에서는 항해사의 적성검사도구 개발을 위한 기초연구로서, 항해사 개인특성에 대한 사전연구 분석, 전문가 회의 및 설문조사 결과를 종합하여 항해사의 사고경향성 평가요인을 선정하고자 하였으며, 이를 기반으로 항해사의 사고경향성을 평가할 수 있는 항해사 적성검사도구의 프로토타입을 개발하고자 하였다.

현행 철도관련기관에 종사하는 안전업무종사자(기관사, 관제사 등)의 업무적성평가제도는 나름의 논리적 토대 하에 설계되어 안전업무종사자의 업무적성검증과 역량의 개발 및 보존에 기여하는 바가 크다. 그러나 한편 조직 내외적인 여러 요인으로 인해 사회, 기술, 가치관(욕구) 등의 제반 환경적 변화추세를 적시에 제도적으로 반영하는데 일정한 한계가 있을 수 있다. 본 논문에서는 이 같은 점을 고려하면서 특히 기관사를 대상으로 한 직무분석결과를 토대로 현행 업무적성평가제도와의 적합관계를 분석하여 바람직한 제도적 틀을 설계하기 위한 기초정보를 제시하려는데 그 목적이 있다.

This study proposes an approach to improve the accuracy of land assessment result focused on the Land Suitability Assessment. The detailed analysis processes are; (a) that they are analyzed considering resistance in distance measurement on the space characteristics of location, and; (b) that an assessment result is measured according to the threshold definition of membership function, which is applied in estimating conservation suitability. The assessment results are; firstly, the method considering resistance better reflects the local characteristics of area with worse accessibility including rivers and mountains than one by linear distance; secondly, the existing method that the maximum value of a target area is defined as the maximum threshold may draw a value evaluated lower than a threshold definition considering the distribution of measured indices. Finally, satellite images are overlapped with the assessed results, the applicability level from the approach proposed by this study is more coincident with the present status. The assessment method proposed by this study can be meaningful in view of that it improves the accuracy of Land Suitability Assessment. Furthermore, it can be applied as SDSS, which can support effective establishment of urban policies, in case of complementing the problems in executing the assessment system.

The purpose of this study is to evaluate human thermal comfort by spatial structure and to explore solutions to improve the thermal environment of a small urban space. The study site was Korea University campus. Thermal conditions were measured to evaluate the quality of the thermal environment in each type of space within the study site. Micrometeorology measurements, analysis of space characteristics for using fish-eye lens photography, and thermal comfort modeling through the use of collected meteorological data, such as temperature and humidity, were performed. Results showed that the level of thermal comfort for humans differs depending on the types of space within the study site. Thermal comfort is better in open spaces than enclosed in the aspect of radiative mean temperature, Predicted Mean Vote(PMV), and Physiologically Equivalent Temperature(PET). This fact is probably due to shadows or buildings or trees that may block solar radiation. Thus, it is necessary to consider the spatial arrangements of buildings and trees to enhance openness and ventilation in the space. Paving materials and exterior building materials should also be selected to lower the radiant temperature. Given these results, a quantitative evaluation on human thermal comfort could propose a way to plan user comfortable small urban spaces. Study methods used and results provided in the study can promote a better way for urban space planning direction to improve environmental quality.

This study examined the difference in the item characteristics in multiple-choice aptitude tests focusing on the response position, response length and question types. A university aptitude test consisting of 80 questions was used for this study. The subjects were 3120 senior high school students from 80 schools nation-wide (liberal arts-1650, natural sciences-1467 patients). The results suggest that item prediction is higher for numbers 2 and 3 (located in the middle) than numbers 1 and 4. The item discrimination was higher for pick-the-'wrong'-items than pick-the-'right'-items. In addition, longer choices are preferred. The suggestions for future research are provided based on these findings.

인쇄 적성 증진제는 식품용 3D 프린팅에서 겔화 소재의 인쇄 적성을 향상시키는 요소 중 하나이다. 이 때, 인쇄 적성 증진제의 평가는 전단응력을 받을 때 일어나는 변형의 정도를 나타내는 전단탄성률 기반으로 한다. 그러나, 전단 탄성률 측정은 식품 원재료의 다양함으로 인해 소재별로 측정하는데 많은 시간과 비용이 소요되는 단점이 있다. 이에 본 연구에서는 FCN과 RNN을 사용하여 전단탄성률을 예측하는 신경망 설계를 제안함으로써 인쇄 적성 증진제의 전단탄성률을 측정하는 시간과 비용을 절감하고자 한다.

Vocational rehabilitation is defined as a process which helps people with disabilities to maintain life of non-disabled people and vocational assessment is a part of it. Traditionally, vocational assessment is performed through using of assessment tools, vocational counseling and so on. It is very efficient to apply vocational assessment to people with disabilities using the internet, but we should provide them with web accessibility. In this paper, we design and implement the aptitude test system for people with visual impairment supporting web accessibility. We develop the aptitude test system using the Holland Test which is the assessment tool of career guidance and counseling. We also show that the aptitude test system for people with visual impairment supports web accessibility more than previous Holland Test which is served in the internet.

The purposes of this study are to apply species distribution modeling in urban management planning for habitat conservation in non-urban area and to provide a detailed classification method for management zone. To achieve these objectives, Species Distribution Model was used to generate species richness and then to compare with the results from land suitability assessment. 59 species distribution models were developed by Maxent. This study used 15 model variables (5 topographical variables, 4 vegetation variables, and 6 distance variables) for Maxent models. Then species richness was created by sum of predicted species distributions. Land suitability assessment was conducted with criteria from type I of "Guidelines for land suitability assessment". After acquiring evaluation values from species richness and land suitability assessment, the results from these two models were compared according to the five grades of classification. The areas with the identical grade in Species richness and land suitability assessment are categorized and then compared each other. The comparison results are Grade1 10.92%, Grade2 37.10%, Grade3 34.56%, Grade4 20.89% and Grade5 1.73%. Grade1 and Grade5 showed the lowest agreement rate. Namely, development or conservation grade showed high disagreement between two assessment system. Therefore, the areas located between urban, agriculture, forest, and reserve have a tendency to change easily by development plans. Even though management areas are not the core area of reserve, it is important to provide a venue for species habitat and eco-corridor to protect and improve biodiversity in terms of landscape ecology. Consequently, adoption of species richness in three levels of management area classification such as conservation, production, planning should be considered in urban management plan.
