Understanding mutual impacts between the ocean and human beings is integral to sustainability of the Earth. Ocean literacy, therefore, is placed as a new paradigm of marine education in North America and Europe. Reflecting this movement, it is necessary for Korean marine educators to discuss conceptualization and future directions of Korean marine education. We reviewed marine education of North America as well as Korea in the domains of formal and informal marine education. We provide the definition, goal, and future recommendations for Korean marine education.

This study is conducted to search about changing earth science contents influenced by the scientific literacy from the 7th curriculum to the 2015 revised curriculum. Earth science area is divided into astronomy, geology, meteorology and oceanography contents. Among the elements of scientific literacy, the contents were analyzed focusing on STS elements. In the astronomical and meteorological content areas, there were aspects of scientific literacy in all periods from the 7th to the 2015 revised curriculum. Except for the 2007 revised curriculum in the geological area and the 7th curriculum in the oceanographic content area, the aspects of scientific literacy appeared at all times. It is emphasized the usefulness of science and technology in the astronomical content area and the use of science in everyday life in geological and meteorological content area. In the oceanographic content area, it is emphasized that content of science related social issue such as resource shortage and environmental pollution. This study can be extended to the fields of physics, chemistry and life science, we suggest to inquire the scientific literacy as a integrated science.

Sea-surface temperature (SST) is one of the most important oceanic variables for understanding air-sea interactions, heat flux variations, and oceanic circulation in the global ocean. Extremely low SSTs from 0℃ down to -2℃ should be more important than other normal temperatures because of their notable roles in inducing and regulating global climate and environmental changes. To understand the temporal and spatial variability of such extremely low SSTs in the global ocean, the long-term SST climatology was calculated using the daily SST database of satellites observed for the period from 1982 to 2018. In addition, the locations of regions with extremely low surface temperatures of less than 0℃ and monthly variations of isothermal lines of 0℃ were investigated using World Ocean Atlas (WOA) climatology based on in-situ oceanic measurements. As a result, extremely low temperatures occupied considerable areas in polar regions such as the Arctic Ocean and Antarctic Ocean, and marginal seas at high latitudes. Six earth science textbooks were analyzed to investigate how these extremely low temperatures were visualized. In most textbooks, illustrations of SSTs began not from extremely low temperatures below 0℃ but from a relatively high temperature of 0℃ or higher, which prevented students from understanding of concepts and roles of the low SSTs. As data visualization is one of the key elements of data literacy, illustrations of the textbooks should be improved to ensure that SST data are adequately visualized in the textbooks. This study emphasized that oceanic literacy and data literacy could be cultivated and strengthened simultaneously through visualizations of oceanic big data by using satellite SST data and oceanic in-situ measurements.

In order to enhance scientific interest and a sense of affinity about ocean, the programs of the oceanic camp 'oceanic summer school' were developed and applied to $4^{th}$ and $9^{th}$-grade elementary and middle school students for 9 years from 2004 to 2012. It was composed of oceanic training for snorkeling, a tour to oceanic institutes and museums near the camp academy place, experimental learning in oceanic-related field, field trips for ocean and earth sciences, and lectures on various subjects of ocean. We developed and implemented 9-kinds of inquiry surveys to evaluate changes in cognitive and affective characteristics, and ocean literacy of students participated at the present oceanic summer camp. Based on the statistical analysis, affective characteristics such as interest, inquisitiveness, passion, and so on, were enhanced. Analysis of ocean literacy revealed that cognitive characteristics of the students were increased by 40%. We presented parents' responses on the programs of oceanic summer school. Some students with less initial interest of ocean have positively changed to make up their minds to be a oceanographer in several years later. In light of this, the summer school can be evaluated to be successfully functioned as a long-term support system for potentially young-talented students in the field of ocean science. This study addresses that long-term implementation of the summer oceanic camp may trigger students with potential talent toward in-depth science in the near future even though it could not bring positive effect immediately. This addresses the necessity of policy supports in order that various programs like the scientific camp should be more constructively developed and executed for next-generation manpower in oceanographic fields.

In terms of the importance of ocean as a present and future resource and the Korean peninsular location, it is strongly urged to develop renewed recognition and educational programs on ocean, so as to respond properly to the newly emerging political changes surrounding the country. By setting up the purpose of marine education as engendering greater interests in and knowledge of ocean, this research suggests that the frame of marine education can be founded appropriately on four educational sub-categories: humanity education, territory education, economy education, and resources and environment education. At an operational scale, this paper particularly analyzed ocean- related contents in the 7th national curriculum in order to find substantial ways for strengthening marine education. The study simultaneously compared the result of content analysis with the curriculum of marine education in other countries, and founded that explicit ocean-related contents in the 7th curriculum were significantly limited. Yet, the study alternatively points out that it is possible to use a variety of teaching materials and apply them for writing textbooks or developing teaching-teaming curriculum. I provide some of the ways for strengthening marine education by using marine-related themes in the curriculum of geography education. Marine is not simply one of the key elements in the discipline of geography. But, more importantly, I suggest that geography is particularly useful in developing various and familiar themes such as swimming beach, fishing villages, ports, marine-bound industrial district and port cities into teaching materials.

Clonorchis sinensis is a main parasite that infects humans by making freshwater fish as an intermediate host in South Korea. There are so many reports about the infestation status of Clonorchis sinensis metacercariae (CsMc) in freshwater fish living in the river, but there are a few studies of fish in the lake. In this study, we examined CsMc in Cyprinid fish sampled from Soyang Lake, Namyang Lake, Andong Lake and Chunchun Lake from 2016 to 2017. Metacercaria of trematodes were found from Hemiculter eigenmanni and Carassius auratus in Namyang Lake, and Zacco platypus and Opsarichthys uncirostris in Soyang Lake. As a result of PCR using Clonorchis sinensis specific primer sets, it was confirmed that the metacercariae from Hemiculter eigenmanni in Namyang Lake was CsMc. This study provides information on CsMc infestation status of Cyprinid fish in four lakes and it is the first report of CsMc infestation in Namyang Lake.

선박충돌사고 원인의 제공 정도를 밝혀 해양사고를 재발방지를 목적으로 1999년 2월 "선박충돌사고 원인제공비율 산정제도"를 마련하였으며, 2007년 1월 원인제공비율 산정지침을 제정하여 시행해 오고 있다. 이 제도의 또 다른 도입목적은 해양안전심판원의 원인제공비율을 민사재판에서 사법부가 적극 인용함으로써 해양사고관련자들 간의 신속한 분쟁해결과 경제적 부담 감송 등에 기여함에 있다. 그러나 민사소송에 있어 제공된 원인제공비율이 과실비율로 인정되는 등의 이유로 원인제공비율 산정제도가 사법권의 침해하고 있다는 문제점도 지적되고 있다. 따라서 본 연구에서는 원인제공비율 산정제도의 시행 이후 이 제도의 시행자 및 사용자 등 전문가 집단을 대상으로 설문조사를 실시하여 제도의 효과 및 문제점 등을 분석하였다. 전문가 집단 응답자의 대부분이 제도의 필요성 (94.3%), 유용성 (88.6%) 및 신뢰성 (73%)을 피력하고 있는 것으로 나타났다. 그리고 이 제도가 필요한 이유로는 "손해배상분쟁의 신속한 해결", "충돌사고 재발방지", 그리고 "이해당사자의 편의제공" 때문임을 알 수 있었다. 그러나 제도의 개선을 위해서는 원인제공 비율의 표시에 있어 보다 객관적인 기준과 정량성 및 전문성의 확보가 필요하다는 지적도 확인하였다. 따라서 원인제공비율 산정제도의 개선방안으로 원인제공비율산정에 대한 신뢰성 및 공정성의 확보, 심판관에 대한 법률적 지식과 법적 소양강화 및 전문법조인의 심판관으로의 영입 등이 필요하다고 판단된다.

This study was to identify the factors of ethical values in nursing students. The survey was conducted in two nursing colleges (n=180) using self-reported questionnaire. The data were analyzed with descriptive statistics, t-tests, ANOVA, Pearson's correlation coefficient and multiple regression analyses using SPSS/WIN 21 software. Influencing factors of ethical values were empathy(t=3.436, p=.001), teaching method except lecture(t=3.037, p=.003), and curriculum track at high school(t=2.309, p=.022). The model was statistically significant explaining 16.2% of the variance (F=11.185, p<.001). This study suggests that strategies for increasing nursing students' ethical values include reinforcing empathy, utilizing various type of teaching method except lecture in nursing ethics class, and allowing high school students applying to college of nursing regardless of their curriculum track.

In this paper, an underwater acoustic digital transceiver is designed and implemented by a multiple DSPs system. We have designed a QPSK transmitter based on look-up table and 13-symbols Barker code is used for frame synchronization. Channel distortions are compensated by a wide-band beamformer based on FIR filter and an adaptive equalize. with RLS algorithm. Uniform linear array (ULA) with four elements is used for the spartial signal processing. 1/2 convolutional code and Viterbi decoder are implemented to overcome time-varying multi-path fading. Also, we show experimental results in the underwater anechoic basin at KRISO/KORDl and Goseong, Donghae and Soyang lake of Kangwon-do.
