유럽 및 미국에서는 안전하며 환경친화적인 연안운송이 활성화되어 있으나 국내의 경우 연안운송에 의한 화물운송은 극히 저조한 실정이다. 본 연구에서는 목포-제주 사이의 해상화물 분석 결과에 기초하여 육상/해상 복합운송시스템을 제안한다. 먼저 목포 및 제주의 반출입 화물 현황을 조사하고 연안항로 및 여객 화물에 대하여 분석한다. 그리고 철도-선박, 트럭-선박의 복합운송과 RORO선 연안운송 등에 대하여 고찰하였다. 마지막으로 목포-제주 항로에 대하여 RORO선을 활용한 연안운송시스템을 제안하고 그 기술적 타당성을 확인하였다. In case of EU and USA, a short sea shipping and coastal shipping which are safer and environmentally better than road transportation are used widely. But a share of freight transport by a coastal transportation is extremely poor in South Korea. In this paper, we propose a Mokpo-Jeju intermodal transportation based on logistics analysis results. Firstly, we investigate a freight and passenger of a Mokpo-Jeju shipping route. And secondly, the intermodal transportations such as sea-train, sea-road, RORO ship system are investigated. Finally, we propose a coastal transportation system utilizing RORO ship system for Mokpo-Jeju shipping route and identify a technical feasibility of a coastal transportation system.

퇴계의 「향입약조」 재구성

김상현(Kim, Sang-hyun) 대한철학회 2021 哲學硏究 Vol.157 No.-

퇴계의 「향입약조」는 율곡의 「해주일향약속」과 더불어 조선향약의 전형으로 평가받는다. 그래서 많은 연구자들이 퇴계의 향약을 연구하기 위해 『퇴계선생문집』에 수록되어 있는 「향입약조」를 분석하였다. 그런데 『퇴계선생문집』에 수록된 「향입약조」보다 퇴계의 향약 사상을 더 온전히 담고 있는 「향입약조」가 있다는 문제 제기가 등장했다. 『퇴계선생문집』본 「향입약조」에 대한 의문이 제기되자 이어서 몇몇 학자들은 『퇴계선생문집』이 간행될 때 퇴계 선생이 초안했던 「향입약조」의 조항 일부가 누락된 채 간행되었다는 주장을 제기하고 있다. 이렇듯이 『퇴계선생문집』본 「향입약조」가 퇴계의 향약 사상을 온전히 담고 있는 자료인지에 대한 논란이 일고 있다. 문제는 퇴계의 향약 사상을 온전히 담고 있는 「향입약조」가 무엇이냐에 대한 이견은 퇴계의 향약 사상이 정확히 무엇인지, 그것의 주요 특징은 무엇인지에 대한 논란을 낳을 수밖에 없다. 그런데도 학계에서는 아직도 이 문제에 대한 규명작업을 하고 있지 않다. 따라서 본 연구의 목적은 퇴계의 사상을 온전히 담고 있는 「향입약조」를 복원하는 것이다. 이와 같은 목적을 이루기 위해 우리는 다음과 같은 과정을 밟을 것이다. 먼저, 퇴계의 「향입약조」와 관련된 선행연구를 검토할 것이다. 다음으로 퇴계 향약이 조선향약의 핵심으로 자리잡는데 결정적 역할을 한 제자 김기의 향약과 퇴계의 향약과 매우 유사한 것으로 평가되는 호남의 양과동향약을 차례로 분석할 것이다. 이렇게 문헌적 탐구가 마무리되면, 마지막으로 퇴계의 사상 내부로 들어가 앞선 연구를 통해 복원한 「향입약조」조항들이 퇴계의 평소 지론과 얼마나 잘 부합하는지를 검토할 것이다. 이와 같은 연구를 통해 『퇴계선생문집』 간행시 누락되었던 벌목 3개 조항과 각 벌목의 세부 규정을 복원할 것이다. This thesis is intended to find Toegye’s Hyang-Lip-yak-jo(鄕立約條) which contains the ideas of Toegye’s Hyangyak entirely. To achieve this goal, we will take the following steps. First, we will review prior research related to Toegye’s Yang-Lip-yak-jo. Through this analysis, we will reveal that there are several types of Toegye’s Hyang-Lip-yak-jo. Next, we will analyze Kim-gi-hyangyak(金圻鄕約) which established Toegye’s Hyangyak as the core of Joseon-Hyangyak, and Yang-Gwa-dong-hyangyak(良苽洞鄕約) which is considered very similar to Toegye’s Hyangyak. When this literature research is completed, we will finally go inside the thought of Toegye and examine how well the previously restored provisions of Hyangyak fit with Toegye’s usual theory. Through this research process, we will restore three provisions of Penalty and the details of each Penalty provision, which were omitted in the publication of the TegyeseonsaengMunjib(退溪先生文集).

Recently, a very large vessel's maneuvering performance, rudder performance and rudder design's importance is considered to be an important subject. There have been few studies on the design process of rudder device before. The aim of this paper is to investigate a design process of rudder device and to propose a generalized design process of rudder device. Firstly, we investigated the rudder device design process of Korean major shipyards. And the differences of a torque calculation method, rudder section design, maneuvering performance examination method, etc were analyzed theoretically. Secondly, the design process of rudder device was divided into concept design, initial design and detail design. In concept design, a rudder area was estimated and its validity was examined. In initial design, rudder profile and design method has been selected through rudder form determination process. And principal dimension and steering gear capacity were determined. Maneuvering performance was also examined by simulation tool. In detail design, design criteria considered in rudder initial design has been investigated thoroughly. Also a rudder torque, rudder cavitation performance and rudder structure analysis were estimated. And maneuvering performance was also examined by model test. Finally, based on the results of investigation, the design process of rudder device was generalized and proposed.

The retrofitting of a thickening unit process is widely considered in municipal wastewater treatment plants in Korea to enhance the anaerobic digestion efficiency. The authors examined the effect of feed concentration (2-34.1 g VS/L) and feed to microorganism (F/M) ratio (0.50-1.35 g VS/g VS) on anaerobic batch digestion of sewage sludge. Methane yield over 90 mL $CH_4/g$ $VS_{feed}$ was found at a feed concentration in the range of 12-26 g VS/L and a F/M ratio below 0.6 g VS/g VS. A high F/M ratio decreased methane yield and rate with oragnic acid accumulation. As sudden increase of sewage sludge concentration prior to anaerobic digestion would jeopardize the digester performance due to the rasied F/M ratio, gradual increase of the sludge feed concentration or an additional biomass retention in the digester is recommended.

Purpose: To compare the effect of single intravitreal injection of triamcinolone acetonide and bevacizumab for the treatment of diabetic macular edema by optical coherence tomography (OCT) patterns. Methods: We classified diabetic macular edema by three OCT patterns: Type 1, diffuse retinal thickening; Type 2, increased retinal thickness associated with the presence of intraretinal cystoid spaces (cystoid spaces with horizontal diameter >300 μm); and Type 3, serous macular detachment. According to this classification, 84 eyes of 42 patients with bilateral diabetic macular edema by the same OCT pattern participated in this study.In each patient,one eye was treated with a single intravitreal injection of bevacizumab 1.25 mg/0.05 ml (IVBI group) and the other eye with a single intravitreal injection of 4 mg/0.1 ml triamcinolone (IVTI group). A comprehensive ophthalmic examination was performed at baseline and at one, three and six months after treatment. Main outcome measures included best corrected visual acuity (logMAR) and central macular thickness measured with OCT. Results: In Type 1, central macular thickness (CMT) reduced significantly in the IVBI group at one month.In Type 2, mean BCVA and CMT improved significantly in the IVTA group at one and three months and in the IVBI group at one month following treatment. In Type 3, CMT reduced significantly in both groups at one, three and six months.However, BCVA did not significantly increase in either group at one, three or six months after treatment. Conclusions: The effects of one single intravitreal injection of triamcinolone and bevacizumab differ by OCT patterns in bilateral diabetic macular edema patients.The correct therapeutic method, depending on OCT patterns of macular edema, should result in better improvement of visual acuity.

High temperature - high pressure apparatus was developed to simulate nickel fewite corrosion products which were main compositions of the radioactive crud in the nuclear power plant. Corrosion product similar to the crud was obtained by a tube accumulator system. Nickel alloy (Inconel 690) and carbon steel (SA106 Gr. C) were corroded at 270 $\^{circ}C$ in the corrosion product generator. Ni ions and Fe ions dissolved by corrosion reaction were able to be transported to the accumulator because the crud generation mechanism was the solubility change with temperature. To evaluate the properties of simulated corrosion products, scanning electron microscope (SEM) observation and EDAX analysis were performed. SEM observation of corrosion product showed the needlelike or crystal structure of oxide depending on precipitating location. The crystal oxide was the nickel ferrite, which was similar to the crud in nuclear power plants.
