본 연구에서는 육상 및 수상 집회, 시위와 비교 상대적으로 보호 및 규율 받지 못하고 있는 해상 집회 및 시위에 대해 공공의 안녕질서를 저해하지 않도록 적절히 규제하면서 동시에 기본권으로서 보호하기 위한 방안을 제시하였다. 먼저, 육상집회 및 시위와 동일하게 보호하고 규율하기 위해 "집시법" 개정을 통하여 해양경비안전관서에서 해상집회 및 시위를 접수받고 이를 관리하는 방안을 제시하였다. 두 번째는 해상의 특수한 환경으로 인해 "집시법" 적용이 곤란할 경우 특별법에 관련 규정을 두고 있는 일본, 미국, 영국과 같이 "해양경비법" 에 해상집회 및 시위와 관련된 내용을 규율하여 국민의 기본권과 공공의 안녕질서 유지 이익이 상호충돌하지 않는 범위에서 해상 집회 및 시위를 관리하는 입법정책적 대안을 제시하였다.

해상 집회 및 시위는 그 장소가 해상이라는 점에서 위험성이 크며, 집회 및 시위의 수단으로 다수의 선박이 동원되기 때문에 제한된 해상 시위 공간에서 시위 선박들 간의 충돌 등 안전사고의 위험이 항상 대두된다. 따라서 해상에서의 집회 및 시위는 육상에서의 집회 및 시위에 비하여 더 엄격한 규제가 필요한 측면이 있다. 그러나 헌법상 기본권으로 보장되는 집회 및 시위에 관한 권리의 중요한 내용 중 하나가 효과적인 집회 및 시위 장소를 선택하는 것이며, 집회 및 시위에 관한 권리는 육상 뿐 아니라 해상에서도 보호되어야 한다. 따라서 해상에서의 집회 및 시위에도 집회 및 시위에 관한 법률이 적용되는 것으로 보아 그에 따른 규제 뿐 아니라 보호도 이루어져야 할 것으로 판단된다. 본 논문은 이와 같은 집회 및 시위에 관한 법률의 적절한 해석을 통하여 해상 집회 및 시위를 적절히 규제하면서도 동시에 보호하는 방안을 도출하고자 하였다.

Objective: This work was conducted to investigate the effects of oxidative stress on meat quality, mitochondrial function, calcium metabolism and ferroptosis of broilers. Methods: In this study, a total of 144 one-day-old male Ross 308 chicks were divided into 3 groups (control group, saline group, and hydrogen peroxide [H₂O₂] group) with 6 replicates of 8 broilers each. The study lasted for 42 d. The broilers in the saline and H₂O₂ groups were intraperitoneally injected with 0.75% saline and 10.0% H₂O₂ on the 16th and 37th day of the experimental period respectively, the injection volumes were 1.0 mL/kg of broiler body weight. On the 42nd day of the experimental period, two chicks were randomly selected from each cage, a total of thirty-six chicks were stunned by electric shock and slaughtered to collect breast muscle samples. Results: The H₂O₂ exposure reduced pH value, increased drip loss and shear force of breast meat (p<0.05), impaired the ultrastructure and function of mitochondria. The H₂O₂ exposure damaged the antioxidant system in mitochondria, excessive reactive oxygen species carbonylation modified calcium channels on mitochondria, which impaired the activities of key enzymes on calcium channel, resulted in the increased calcium concentration in cytoplasm and mitochondria (p<0.05). In addition, the H₂O₂ exposure increased the iron content and lipid peroxidation (p<0.05), which induced ferroptosis. Conclusion: Oxidative stress could impair meat quality by causing mitochondrial dysfunction, resulting in calcium metabolism disorder and ferroptosis.

사용후핵연료 건식저장의 실증연구는 건식저장 시스템의 안전성과 사용후핵연료의 저장 건전성 평가를 위한 확증적인 데이터 생산을 위하여 수행되어 왔다. 사용후핵연료의 건식저장을 가장 먼저 시작하였고 핵연료 건전성에 대한 법적 요건이 엄격하게 제시되어 있는 미국에서는 건식저장의 개시, 인허가 갱신을 위하여 주목할만한 몇몇 실증연구 프로그램을 운영한 바 있다. 건식저장 초기 단계에 건식저장 시스템 성능 검증 목적으로 실증연구가 수행된 바 있으며 저연소도 사용후핵연료의 건식저장 인허가 갱신을 위하여 건식저장 특성평가 프로젝트를 진행한 바 있다. 현재는 고연소도 사용후핵연료 인허가 연장을 위한 실증연구가 진행 중이며 이 연구는 향후 최소 10년이상 진행될 것으로 예상된다. 건식저장을 본격적으로 시작하지 않은 우리나라에서는 미국에서 진행해온 이러한 건식저장 실증연구가 훌륭한 타산지석이 될 것으로 생각되며 이에 본 논문에서는 미국의 건식저장 실증연구 프로그램의 과거와 현재를 분석하고 우리나라에서 진행할 필요가 있다고 사료되는 실증연구에 대한 제언을 담았다.

It is very important to secure hydrogen acceptability to achieve the hydrogen economy. This study empirically analyzed the factors affecting acceptance by using the results of a questionnaire administered to residents of Jeonju-Wanju Hydrogen Demonstration City. The results indicated that the safety of hydrogen infrastructure and local industry and economic growth positively affected acceptance. In particular, local industry and economic growth were more effective in improving resident acceptance. As policy factors, support for government policies and disclosure of information on projects were also positive factors. As perceptual factors, the higher interest in hydrogen and less safety concerns positively affected acceptability. Therefore, as far as hydrogen safety is concerned, it seems necessary to support local industry development to improve acceptability, disclose information related to industrial development, and introduce targeted experience programs.

There exists required safety integrity level (SIL) to assure safety in accordance with international standards for every electrical / electronics / control equipment or systems with safety related functions. The SIL is allocated from lowest level (level 0) to highest level (level 4). In order to guarantee certain safety level that is internationally acceptable, application of methodology for SIL allocation and demonstration based on related international standards is required. However, application standard differs from every industry in domestic or international for application on mythology for allocation and demonstration of SIL. Application or assessment is not easy since absence on clear criteria or common definition. This research studied not only fundamental concept of SIL required to guarantee safety in accordance with international standards for safety related equipment and system, but different types of methodologies for SIL allocation. Specifically, SIL allocation for Platform Screen Door system of railway is studied applying methodology of severity of accidents and risk graph among different methodologies for SIL allocation.

Objective: This study was conducted to investigate the effects of dietary corn resistant starch (RS) on the intestinal morphology and barrier functions of broilers. Methods: A total of 320 one-day-old broilers were randomly allocated to 5 dietary treatments: one normal corn-soybean (NC) diet, one corn-soybean-based diet supplementation with 20% corn starch (CS), and 3 corn-soybean-based diets supplementation with 4%, 8%, and 12% corn resistant starch (RS) (identified as 4% RS, 8% RS, and 12% RS, respectively). Each group had eight replicates with eight broilers per replicate. After 21 days feeding, one bird with a body weight (BW) close to the average BW of their replicate was selected and slaughtered. The samples of duodenum, jejunum, ileum, caecum digesta, and blood were collected. Results: Birds fed 4% RS, 8% RS and 12% RS diets showed lower feed intake, BW gain, jejunal villus height (VH), duodenal crypt depth (CD), jejunal VH/CD ratio, duodenal goblet cell density as well as mucin1 mRNA expressions compared to the NC group, but showed higher concentrations of cecal acetic acid and butyric acid, percentage of jejunal proliferating cell nuclear antigen-positive cells and delta like canonical Notch ligand 4 (Dll4), and hes family bHLH transcription factor 1 mRNA expressions. However, there were no differences on the plasma diamine oxidase activity and D-lactic acid concentration among all groups. Conclusion: These findings suggested that RS could suppress intestinal morphology and barrier functions by activating Notch pathway and inhibiting the development of goblet cells, resulting in decreased mucins and tight junction mRNA expression.

The importance of reliability and safety, recently, shows a tendency to increases in railway system constructions and projects. At the point of view of safety, especially, the railway authority proposes an establishment of the safety case that is the documented demonstration that products comply with the specific safety requirements in railway industry. In case of reliability activities, there is no systematic documented demonstration in the railway industry. At this circumstance, this study presents the establishment of Reliability, Availability and Maintainability Case for railway system based on the MoD(Ministry of Defence) 00-42. This RAM Case will support that systems and products produced from suppliers or manufacturers meet the specific RAM requirements during the system life cycle(i.e, from design to operation & maintenance) through systematic process and evidences. Also, it is expected that railway system operations will be managed and supported from reliability activities in accordance with RAM Case.
