실습생 및 초급항해사에게 항해 중 가장 기본적으로 요구되는 충돌회피를 위한 선박조종 실습은 법적 책임 및 타 선박과의 불규칙한 조우로 인하여 직접적인 충돌회피 조종 실습이 곤란할 뿐만 아니라 타 선박과의 조우 상황 자체가 극히 제한되어 있는 실정이다. 이에 이 연구는 한국해양대학교 실습선 한나라호의 2007년 원양항해 중 타 선박과의 조우형태를 조사하여 해양계열 대학 실습생 및 초급 항해사에게 실제 해역에서 발생할 수 있는 조우상황별 위험도를 분석하여 이를 기초로 하여 충돌회피를 위한 효율적인 판단 능력 향상을 위한 기초 실습교육 자료를 개발하고자 한다. 그리고 추후에는 이러한 자료를 선박조종시뮬레이터에 적용하여 임의의 조우 상황하에서 안전한 선박조종이 가능하도록 교육 훈련함으로써 보다 효율적인 실습교육에 이바지 할 것으로 판단된다.

항해 중에 항해사의 상황인식 능력은 사고와 직결되는 능력이라고 할 수 있다. 본 연구에서는 선박들이 조우하는 상황에서 항해사들이 어떻게 상황인식을 하고 있는지 조사하고 분석하였다. 본 실험은 선교 시뮬레이터에서 실시되었으며, 다양한 선박조우 상황의 시나리오를 구현하였다, 본 연구의 결과로써 항해사들의 상황인식에 문제점을 도출하였으며, 이를 예방할 수 있는 교육방법들을 제시하였다.

Chicken feathers could be classified into early-feathering (EF) and late-feathering (LF) depending on the development and patterns of the wing and tail feathers. Currently, feather-sexing is a widely used chick sexing method in the industry. This study was carried out to suggest the method of classifying of EF and LF chicks to establish auto-sexing Korean native chicken (KNC) strains. The development and morphology of wing feathers and tail feathers in 856 KNCs from hatching to 55-days old were analyzed to classify EF and LF chicks. We also performed PCR analysis using K-specific gene primers to confirm the agreement between the phenotypes and genotypes of EF and LF chickens. In the results, the EF chicks had long primaries and coverts, and there was a significant difference in length between primaries and coverts. The LF chicks had shorter primaries and coverts than the EF chicks, and showed little difference in the length between primaries and coverts. LF chicks could be classified into four groups: LF-Less, LF-Scant, LF-Equal and LF-Reverse according to their wing feather patterns. EF chicks had 1.5 times longer primaries than LF chicks until they were 15-days old, but the lengths were almost the same at 50-days old. The tail feathers of the EF chicks were apparent at 5-days old, but those of the LF chicks were short and indefinite at that time. When EF and LF chicks were classified by the length of primaries being more or less than 9 mm, the classification accuracies for EF and LF chicks were 96.2% and 85.4%, respectively, compared to the PCR results. In conclusion, juvenile EF and LF KNC showed distinct differences in feather development and morphology, and could be easily distinguished at one day-old.

The vessel encounter data collected from the vessel trajectories in the maritime traffic situation is possible to analyze vessel collision and near-collision risk using statistical method. In this study, analyzing variables extracted from the vessel encounter data using factor analysis, we determine main factors effecting vessel collision risk from vessel encounter data. In order to calculate each factor, it used principal component analysis for factor analysis after normalization and standardization of vessel encounter variables. As a result of the factor analysis, main effect factors are summarized into the vessel approach factor and collision avoidance variance factor.

본 연구는 OSV(Offshore Support Vessel)의 운동응답 특성을 파악하기 위해 조우주파수와 선속변화에 따라 상하동요 및 종요에 대해 수치해석을 수행하였고 유효마력에 대한 실험값과 비교 해석하였다. 연구결과 뷰포드 스케일(Beaufort Scale) 2의 해상조건에서 조우각 $30^{\circ}$로 고속항주시 상하동요는 가장 크게 나타났고, 뷰포드 스케일 3 및 4일 경우 조우각 $90^{\circ}$로 저속항주시 상하동요가 가장 크게 나타났다. 종요의 경우, 뷰포드 스케일이 증가함에 따라 선형적으로 증가하였고, 조우각 $30^{\circ}$에서 고속항주시 가장 큰 값이 나타났다.

The usefulness of media representations for assessing normative standards depends in part on how accurately media reflect "on-the-ground" resource conditions. This study compared encounter standards based on still and moving pictures to assess movement effects. The study location was the Jungmoeri area of Mudeungsan Provincial Park (MPP) in Korea. A total of 50 college students participated in a laboratory experiment where they evaluated still and moving pictures constructed using Photoshop and Flash computer programs. For the maximum acceptable number (MAN), however, there was no significant difference of ratings between still and moving pictures, and the overall encounter norm curves were nearly identical. There were some "method findings" for ordering effects and percent of people moving, but for a resource manager developing standards there was no advantage to the more complex logistics of using moving pictures to assess this particular impact. The trade-offs of using more sophisticated media are discussed, and more research is needed to further explore factors such as movement of sound in evaluation of other resource conditions.

This study measured the present number of encounters and established the evaluation criterion for the allowable number of encounters in the Seoseokdae summit area (SSA) of Mudeungsan National Park to examine managerial conditions of the number of visitors to the Seoseokdae trail section (STS). Data were obtained from a questionnaire survey of 263 visitors to STS selected through convenient sampling during June 2019. The average number of encounters in SSA was 18.7. Most of the respondents (95.4%) encountered fewer than 30 other visitors. The average maximum number of simultaneous users (AMNSU, measured at 15-minute intervals) in SSA was 13.4 persons (range: 3~31 persons). The AMNSU by the hour was the highest with 21.0 persons at 13-14, followed by 19.8 persons at 11-12, 15.5 persons at 14-15, 15.3 persons at 12-13, 12.3 persons at 10-11, and 10.8 persons at 8-9. Acceptable encounter number (AEN) developed by long-question format (LQF) was 59.2 persons, and that by short-question format (SQF) was 55.1 persons. AEN of the respondents who preferred "near-nature experience" at 27.5 persons was fewer than those who preferred "resort/tourism area like experience" at 46.6 persons. The present number of encounters and AMNUS (range: 3~31 persons) in SSA were fewer than AENs derived from LQF (59.2 persons) and SQF (55.1 persons). Eighty-three percent of the respondents preferred "near-nature experience," while only 10.5% of the respondents preferred "resort/tourism area like experience." 78.4% of the respondents did not perceive that SSA was crowded. The absolute majority of the respondents (92.3%) answered higher personal AEN than the perceived encounter numbers (PEN). The gaps between the personal AEN and the PEN were negatively correlated with perceived crowding.
