  • Marine algal flora and community structure were seasonally investigated at Oryukdo, on the southeast coast of Korea, from March 2011 to February 2014. A Total of 66 seaweed species including 6 green, 7 brown and 53 red algae were identified and 23 species were found throughout the survey period. Seaweed biomass was maximal during summer in 2012 (2276.2 g wet weight $m^{-2}$) and minimal in winter in 2012 (9.1 g wet weight $m^{-2}$). The dominant species in term of biomass were Undaria pinnatifida, Dictyopteris prolifera, Dictyota dichotoma, Sargassum horneri, Rhodymenia intricata, Acrosorium polyneurum, and Polyneura japonica during the suvery period. The flora could be classified into six functional groups: coarsely branched form (30.3%), filamentous form (24.2%), thick leather form (19.7%), sheet form (15.2%), jointed calcareous form (7.6%), and crustose form (3.0%). The numbers of marine algal species in the Oryukdo area were markedly reduced when compared with previous studies at Dongbaekseom in 1971. These results suggest possible future changes in the algal vegetation, considering the physical and chemical pollution loadings in the coastal marine environment of this area.

  • Community structures and species composition in benthic crustacean around Oryukdo of Busan was investigated using a SCUBA diving in 2011. A total 115 species, 51 families, and 4 taxa were collected during the sampling periods. Species were included 52 species in amphipoda, 49 in decapoda, 8 in isopoda and 6 in thoracica. On cluster analysis, the benthic crustacea community was classified into three groups based on the species composition: group A occurred in spring, group B in autumn and winter and group C in summer. Species composition in benthic crustacean corresponded with the water temperature.

  • Seasonal variation of species composition in marine organisms around Oryukdo of Busan was investigated using a gill net between 2009 and 2011. A total of 82 species, 52 families, and 6 taxa were collected during the sampling periods. Species were included two species in Cnidaria, one in Urochordata, 12 in Mollusca, 12 in Crustacea, seven in Echinodermata, and 48 in Pisces. The dominant species were Crepidula onyx, Asterina pectinifera, Ceratostoma burnetti, Asterias amurensis, Anthocidaris crassispina, and Trachurus japonicus. These six species accounted for 48.4% in the total number. Diversity indices were highest in spring 2009 (2.77) and lowest in spring 2011 (1.66). Seasonal variation of species composition and abundance in marine organisms corresponded with the water temperature.

  • The purpose of this study was to develop poetrytherapy program and to test it's effect on emotional intelligence of middle school students. Sixty-six(male 33, female 33) middle school students participated in this study. Thirty-three students were assigned to experimental group and control group respectively. The program which is composed of 14 sessions was applied to experimental group for 16 weeks. Subjects completed Emotional Intelligence Test. Collected data were analyzed using t-test and ANCOVA. The results of statistical analyses showed that there were statistically significant differences in emotional intelligence test scores between experimental group and control group. Based upon these results, it is concluded that poetrytherapy program was effective in improving emotional intelligence of middle school students.

  • 우리나라 주요 항만의 입출항 통항패턴을 연구하기 위한 사전 연구로서, 부산항에 입 출항하는 위험화물운반선의 통항량을 항만운영정보시스템(Port Management Information Systim, Port-MIS) 자료를 이용하여 사전 조사하고, 통항량이 가장 높은 각 계절별 연속 3일을 선별하였다. 해양안전종합정보시스템(General Information Center on Maritime Safety & Security, GICOMS) 자료를 이용하여 선별된 12일간 위험화물운반선의 부산항 주요 통항로의 통항 패턴을 분석하였다. 또한 주요 입출항 지점인 북항 오륙도 방파제와 감천항 동방파제의 위험 화물운반선의 통항 이격거리를 분석하였다. 항로 단면에서 선박의 궤적이 정규분포를 이룬다는 가정을 근거로 해상교통안전진단 등에서 정규분포의 누적 확률분포 함수를 이용하여 충돌확률을 추정하여 사용하고 있지만, 오륙도 방파제 입출항 및 감천항 동방파제 입항에서의 선박의 항해 궤적은 KS-test 및 SW-test를 이용한 정규성 검정결과 정규분포를 따르지 않는 것으로 평가되었다. 특히 북항에서는 선박의 우측통항 경향이 두드러지게 나타났다. 일반적인 통항이론의 적용보다는 항만의 특성에 맞는 통항모델을 개발하여, 해상교통안전진단 등에서 적용하는 것이 바람직하여 이에 대한 후속연구가 필요할 것으로 판단된다.

  • 지질유산은 지질다양성을 보전하기 위해 지정된 구체적인 개개의 지형 지질사례를 의미한다. 지오투어리즘은 지질유산을 대상으로 하여 지질과 지구의 역사에 대한 이해를 구하는 활동으로 지질자원의 다양성을 보전하고 이를 통하여 지역의 발전을 가져오는 광범위한 활동이다. 부산국가지질공원 인증에 따른 이기대-오륙도 지질명소의 탐방객 급증은 핵심영역인 지오투어리즘의 개발과 적용을 통한 지질명소와 지질공원의 효율적인 운영이 필요하게 되었다. 지질유산별 상세한 가치평가를 통하여 응회질 퇴적암, 함각섬석암맥, 구리광산, 돌개구멍이 심화단계의 중심점으로 화산쇄설암, 해식동, 해식애, 파식대, 토르와 도서(島嶼)가 기초적인 중심점으로 설정되었다. 이 중심점들을 토대로 본 연구에서는 교양과 전문가 수준의 단계별 지오투어리즘과 개인, 가족 그리고 소규모 그룹으로 구성될 수 있는 단위별 지오투어리즘에 대한 개념을 정립하고, 각급 학교 단위 규모의 지오투어리즘에 대한 방향을 제시하였다.

  • The occurrence variations of decapods by season and depth off Oryuk Islets, Busan were investigated at seven stations in April and October 2009, July 2010 and January 2011. Decapods were collected by SCUBA diving at 5 m and 10 m depths. 46 species belonging to 18 families in 3 orders were identified. Pilumnus minutus, Pugettia intermedia, Pachycheles stevensii, and Paguristes japonicus were dominant species, comprising 73.0% of total decapods. P. minutus and P. intermedia were abundant in all seasons (except summer) while P. stevensii and P. japonicus were abundant in fall and summer. Dominant species were divided into three groups (resident species, seasonal species and temporary species) on the basis of their occurrence patterns. P. minutus and P. intermedia were resident species while P. stevensii, P. japonicus were temporary species. The species number, density and biomass of decapods were fluctuated by seasons. They were highest in fall and lowest in winter. This study implied that the variations of species number and density of decapods were significantly related with seasonal change of water temperature.
