This study investigated the species composition and community structure of aquatic organisms captured using coastal beam trawling in Gomso Bay, Jeollabuk-do, from January to December 2022. Throughout the experimental period, a total of 20,246 individuals belonging to 94 marine species were captured, with a combined biomass of 602,828 g. Fish exhibited the highest abundance, comprising 56 species, followed by crustacea (21 species), bivalvia (8 species), cephalopoda (5 species), gastropoda (3 species), and holothuroidea (1 species). The dominant species was Leiognathus nuchalis, constituting 14.0% of the total individuals, followed by Portunus trituberculatus at 12.1%, Oratosquilla oratoria at 10.4%, Crangon hakodatei at 9.9%, and Metapenaeus joyneri at 7.9%. The diversity index ranged from 1.72 to 2.55, with the lowest diversity observed in March and the highest in July. Cluster analysis based on species composition of the 27 most common species showed that aquatic organisms were divided into three groups: spring and summer organisms (Group A) and summer organisms (Group B) and autumn and winter organisms (Group C).

본 연구는 1960년대에 향수(Nostalgia) 주제를 가진 트로트 곡의 특징을 연구하였다. 1960년대 트로트 가사가 고향에 대한 향수를 어떤 방식으로 다뤘으며, 해당 트로트 가사가 의미하는바가 무엇인지를 고찰하였다. 그리고 고향에 대한 그리움과 회상을 표현하는 가사 속 단어들 및 타향을 부정하는 단어들 속에 내재된 감정을 분석하였다. 본 연구는 트로트 곡에서 드러나는 고향에 대한 향수에 관한 내용의 가사를 분석함으로써, 가사 분석의 다양성을 고찰하는 것에 목적을 두고 있 다. 1960년대 트로트 가사에는 고향에 대한 그리움과 회상 그리고 가족과 연인에 대한 사랑이 주 로 나타났으며 한국적 정서가 드러나는 시대를 반영한 이야기들을 표현한 단순 명료한 가사로 이 루어져있었다. 또한 1970년대에는 추상적인 이별이야기를 담는데 주력하는 양상을 보인 반면, 1960년대에는 직접적인 단어로 표현함으로써 곡의 애절함과 씁쓸함이 보다 더 잘 드러났으며 대중 들 기억에 남는 가사로 공감을 더했다. 대중가요에서 고향을 주제로 한 가사에서는 사람의 감성을 움직이게 하며 향수를 불러일으키지만 시대적 배경과 대중들의 상황과 상태, 염원을 분석한다면 가사에 담긴 함의를 구체적으로 파악할 수 있으며 많은 창작자들이 가사를 분석하는 것에 도움이 될 것이라고 예상한다.

이 연구는 광역자치단체 조례 비교 분석을 통해 가족돌봄 청년 지원 조례 개정 방안을 도출하기 위함이다. 이를 위해 국가법령정보센터의 자 치법규시스템 자료를 활용하여 전국 11개 광역자치단체의 ‘가족돌봄 청 년 지원 조례’를 비교하였다. 조례 비교를 위한 분석틀로서, 규범적 타당 성 체계에 해당하는 권리성(조례의 목적지향성, 자치단체장의 책무성), 적용대상의 보편성, 급여종류의 포괄성, 자치단체장의 재정책임성과 규범 적 실효성 체계에 해당하는 전달체계의 책임성 및 통합성, 인력의 전문 성을 활용하였다. 분석 결과, 광역자치단체마다 차이가 있음을 확인하였 다. 분석결과를 기초로 한 조례 개정 논의로서, 주민의 권리 규정 신설, 자치단체장의 책무성과 재정책임성에 대한 임의규정을 강행규정으로 변 경을 제안하였다. 본 연구를 통해 가족돌봄청년의 삶에 대한 사회적 관 심이 제고되고, 사회복지조례에 관한 비교 연구가 활성화되기를 기대한 다.

PURPOSES : This study defines private and public service providers connected to a public data hub in a smart city and examines the information that should be exchanged between them. The information exchange scheme covers data exchange at a minimum level. METHODS : First, we reviewed the entities participating in the emergency charging service and designed the scope of information linkages between the entities. Second, we diagnosed the main information linkages according to a service flowchart. Third, we reviewed the basic information requirements linked to actors participating in the service. Finally, we derived and presented information linked to the subjects. RESULTS : In addition to the basic requirements, the number of data-exchange information sets specified was four, which was the scope of the aforementioned study. We defined and analyzed an efficient information exchange system between various actors involved in emergency charging services. Data were defined based on interactions between service users, operators, providers, and data hubs. Each set had a different scope and purpose. CONCLUSIONS : Information collected and provided by emergency charging service providers in connection with a data hub that manages urban energy was proposed.

PURPOSES : The effect of yellow carpet visibility enhancement was verified and its impact on traffic safety for effective introduction of traffic safety facilities was studied. METHODS : There is currently no scientific evidence demonstrating that yellow carpets improve pedestrian awareness. In this study, the effect of increasing visibility caused by the installation of yellow carpet was verified, and the effect of improving the level of traffic safety was examined through an objective analysis. A drone was used to collect and analyze video data to compare the driving speeds of vehicles passing near yellow carpets at six different sites and diagnose the effects of speed reduction. RESULTS : The results showed that the visibility improvement values before and after the installation of the yellow carpet differed from place to place, but a visibility improvement effect existed in certain cases. In terms of the adequacy of the installation site, the yellow carpet had no deceleration effect on vehicles driving on signalized local streets and collector highways. It was found that there was a speed reduction effect on unsignalized local streets. CONCLUSIONS : To enhance traffic safety promotion, yellow carpets should be placed on unsignalized local streets. It is important to place the yellow carpet in the right place in a proper manner.

PURPOSES : We propose a framework to evaluate the reliability of integrating homogeneous or heterogeneous mobility data to produce the various data required for greenhouse gas emission estimation. METHODS : The mobility data used in the framework were collected at a fixed time from a specific point and were based on raster data. In general, the traffic volume for all traffic measurement points over 24 h can be considered raster data. In the future, the proposed framework can be applied to specific road points or road sections, depending on the presence or absence of raster data. RESULTS : The activity data required to calculate greenhouse gas emissions were derived from the mobility data analysis. With recent developments in information, communication, and artificial intelligence technologies, mobility data collected from different sources with the same collection purpose can be integrated to increase the reliability and accuracy of previously unknown or inaccurate information. CONCLUSIONS : This study will help assess the reliability of mobility data fusion as it is collected on the road, and will ultimately lead to more accurate estimates of greenhouse gas emissions.
