H-slant submersions

박광순 대한수학회 2012 대한수학회보 Vol.49 No.2

In this paper, we define the almost h-slant submersion and the h-slant submersion which may be the extended version of the slant submersion [11]. And then we obtain some theorems which come from the slant submersion's cases. Finally, we construct some examples for the almost h-slant submersions and the h-slant submersions.

Semi-slant submersions

박광순,Rajendra Prasad 대한수학회 2013 대한수학회보 Vol.50 No.3

We introduce semi-slant submersions from almost Hermitian manifolds onto Riemannian manifolds as a generalization of slant submersions, semi-invariant submersions, anti-invariant submersions, etc. We obtain characterizations, investigate the integrability of distributions and the geometry of foliations, etc. We also find a condition for such submersions to be harmonic. Moreover, we give lots of examples.

The Korea Operational Oceanographic System (KOOS) was developed at the Korea Institute of Ocean Science and Technology (KIOST) to produce real-time forecasting and simulation of interdisciplinary multi-scale oceanic fields. This offers valuable information to better mitigate coastal disasters, such as oil spills and other marine accidents, and provides the necessary ocean predictions to support the marine activities of government agencies, marine industries, and public users. The KOOS became operational in March 2012, and consists of several operational modules and realtime observations, including satellite remote sensing, coastal remote monitoring stations using high-frequency radar, and ocean observatories. The basic forecasting system includes weather, regional and high-resolution coastal circulation and wave prediction models; the practical application system includes storm surges, oil spills, and search and rescue prediction models. An integrated maritime port prediction system and data information and skill assessment systems are also part of the KOOS. In this work, the performance of the numerical models was evaluated by the skill assessment systems. From the monthly and yearly skill assessments, the models showed reasonable skill in predicting atmospheric and oceanic states except for the regional ocean circulation models. The ongoing development and improvement of the KOOS includes improvement of the model skills through the upgrade of the satellite-based sea surface temperature algorithm, the enhancement of the ocean monitoring ability, the upgrade of the forecasting models for higher spatial resolutions and the application of data assimilation techniques improved with the feedback from the skill assessment report.

Development of an Operational Storm Surge Prediction System for the Korean Coast

박광순,이종찬,전기천,김상익,권재일 한국해양과학기술원 2009 Ocean and Polar Research Vol.31 No.4

Performance of the Korea Ocean Research and Development Institute (KORDI) operational storm surge prediction system for the Korean coast is presented here. Results for storm surge hindcasts and forecasts calculations were analyzed. The KORDI storm surge system consists of two important components. The first component is atmospheric models, based on US Army Corps of Engineers (CE) wind model and the Weather Research and Forecasting (WRF) model, and the second components is the KORDI-storm surge model (KORDI-S). The atmospheric inputs are calculated by the CE wind model for typhoon period and by the WRF model for non-typhoon period. The KORDI-S calculates the storm surges using the atmospheric inputs and has 3-step nesting grids with the smallest horizontal resolution of ~300 m. The system runs twice daily for a 72-hour storm surge prediction. It successfully reproduced storm surge signals around the Korean Peninsula for a selection of four major typhoons, which recorded the maximum storm surge heights ranging from 104 to 212 cm. The operational capability of this system was tested for forecasts of Typhoon Nari in 2007 and a low-pressure event on August 27, 2009. This system responded correctly to the given typhoon information for Typhoon Nari. In particular, for the low-pressure event the system warned of storm surge occurrence approximately 68 hours ahead.

고등학생과 대학생들의 인터넷 엽기콘텐츠 이용동기에 관한 연구

박광순 청주대학교사회과학연구소 2006 한국사회과학연구 Vol.28 No.1

본 연구는 청소년과 대학생들의 인터넷 엽기콘텐츠 이용동기와 이용만족도에 미치는 영향의 정도를 파악하기 위해 이루어졌다. 분석결과 청소년 집단에서의 인터넷 엽기콘텐츠 이용동기는 사회현실 비판, 혁신적사고/커뮤니케이션, 사회현실 파악, 오락, 신기성, 기존관념탈피, 선정성 등과 같이 모두 7개의 인자가 추출되었다. 대학생 집단에서는 혁신적 콘텐츠, 오락/휴식/차별성, 커뮤니티 참여, 사회현실 비판, 사회 현실 파악 등과 같이 모두 5개의 인자가 추출되었다. 두 집단에서 추출된 요인들 가운데 청소년 집단에서의 신기성, 기존관념탈피, 선정성 등은 청소년 집단의 특성이 반영된 것으로 대학생 집단과 구별되는 요인들이다. 또한 엽기콘텐츠 이용동기 요인이 이용만족도에 미치는 영향에 관한 분석결과를 살펴보면, 청소년 집단에서는 사회현실 비판, 사회현실 파악, 신기성 등의 요인이 대학생 집단에서는 혁신적 콘텐츠, 오락/휴식/차별성, 사회적 비판 등의 요인이 이용만족도에 영향을 미치는 것으로 나타났다. 이처럼 이용동기의 일부 요인만이 이용만족도에 영향을 미치는 것으로 나타난 본 연구결과는 기존 연구에서 이용동기 대부분의 요이 이용만족도에 영향을 미친다는 결과들과 구별되는 것이라 할 수 있다. This paper is aimed at understanding the two questions 'What are the use motives and satisfaction of the Internet grotesque contents by high school and college students?' and 'What does the factors of grotesque use motive have an effect on the use satisfaction?'. As a result of the analysis, the use motives of the Internet grotesque contents by a group of high school students were extracted as 7 elements. They are the criticism of social realities, the renovative thought, the communication, the understanding of social realities, the entertainments, the novelty, the break from the existing convention, the eroticism. In a group of college students, they were extracted as 5 elements. They are the renovative contents, the entertainments/rest/discrimination, the participation of community, the criticism of social realities, the understanding of social realities. Of the elements extracted from two groups, the novelty, the break of the existing convention and the eroticism in a group of high school students are the elements that high school students' distinction is reflected and that are differentiated from the group of college students. Also, the analytical results of the effect of the elements in the use motives of grotesque contents on the use satisfaction were shown as follows; in case of high school students' group, the criticism of social realities, the understanding of social realities, the novelty, etc. had an effect on the use satisfaction; and in case of the college students, the renovative contents, the entertainments/rest/discrimination, the criticism of social realities, etc had an effect on the use satisfaction.

기존 교량의 내진성능평가를 위한 개선된 내진보강 우선순위 결정

박광순,주형석,최홍철,김익현 한국지진공학회 2009 한국지진공학회논문집 Vol.13 No.6

기존교량의 내진보강 우선순위 결정방법은 교량을 지진도 그룹으로 분류한 후 교량의 취약도 및 영향도를 고려하여 4개의 내진그룹으로 분류된다. 그러나, 현재 사용되고 있는 내진보강 우선순위 결정방법을 442개의 국도상 기존교량에 적용한 결과 비합리적인 부분이 조사되었다. 지진도를 정량화하여 좀 더 세분화할 필요가 있고, 연속경간장이 긴 PSC 박스거더교량의 취약도가 과소평가되는 모순점을 개선할 필요가 있었으며, 영향도 수준 또한 취약도 수준으로 증가시킬 필요가 있었다. 본 연구에서는 기존 교량의 조사 결과를 근거로 기존 평가기법을 수정 보완하여 개선된 내진보강 우선순위 결정방법을 제안하였다. Existing bridges are classified into 4 retrofit groups using the current preliminary screening method, considering key terms such as seismicity, vulnerability and social impact effect. However, some irrationality was found when the current method was applied to 442 existing bridges. As a result, it was determined that quantification and a more detailed classification of seismicity were required. The estimation of the vulnerability of box girder bridges having a long span length should be improved, as this showed a tendency to underestimate. It was also necessary to increase the level of social impact effect to that of vulnerability. In this study, an improved preliminary screening method has been proposed on the basis of the estimation results of existing bridges.
