최근 국내 멧돼지 문제는 농작물 피해 및 도심 출몰로 인하여 사회적으로 심각한 상황에 직면해 있다. 본 연구는 경남 거창군의 멧돼지에 의한 농작물 피해사례를 바탕으로 피해에 영향을 끼치는 환경 요인들에 대하여 파악하고자 2012년 5월부터 10월까지 수행 되었다. 농작물 피해 분석 결과 주로 8월과 9월 사이 피해가 가장 많이 발생하였고, 벼의 빈도가 가장 높았으며 피해 강도는 고구마가 가장 높은 것으로 나타났다. 이는 멧돼지의 농작물 선호성과 특정시기에 대한 가용성과 관련이 있는 것으로 판단된다. 또한 농작물 피해에 경사, 지형기복, 산림과의 거리, 수계로부터의 거리, 도로로부터의 거리, 주거지로부터의 거리의 요인들이 영향을 미치는 것으로 나타났다. 피해 강도에 따른 환경요인의 차이는 나타지 않아 멧돼지는 한번 피해를 끼친 농경지를 지속적으로 방문하여 피해를 누적 시키는 것으로 파악된다. 따라서 멧돼지에 의한 농작물 피해를 저감시키기 위해서는 피해가 발생할 수 있는 곳에 멧돼지가 비선호하는 작물로 대체 재배하며 전기펜스 설치, 엽사와 포획틀을 이용한 멧돼지 개체수 조절이 필요할 것으로 판단된다.

Biogenic amines (BAs) are toxic nitrogenous compounds and formed by the microbial decarboxylation of amino acids during fermentation. Consumption of fermented foods high in BAs can pose the adverse health effects. The objective of current study was to develop a reduction method of BAs in fermented soybean paste by applying catechins during fermented koji manufacturing step. Analysis of BAs in fermented soybean paste was conducted using High Performance Liquid Chromatography (HPLC). The levels of Putrescine decreased for 63.7%, 60.1%, 76.1%, 73.4% for 0.3% addition of Epicatechin, Epicatechin gallate, Epigallocatechin, Epigallocatechin gallate, respectively. The levels of Cadaverine decreased for 24.3%, 34.3%, 42.6%, 37.2% for 0.3% addition of Epicatechin, Epicatechin gallate, Epigallocatechin, Epigallocatechin gallate, respectively. Especially, The best reduction effect of BAs appeared for 0.3% addition of Epigallocatechin. Current study demonstrated the potential use of catechins for reduction of biogenic amines in fermented soybean paste model. Finding from this research can practically guide fermented food industry by providing practical application of additives for reduction of BAs.

Climate change is a very vital issue that can be no longer avoided. Korea has been a top-level country Iin dealing with carbon dioxide emissions since 1960. Many studies have been conducted to suppress or eliminate carbon dioxide emissions, which account for a large portion of greenhouse gases. Carbon Capture and Storage (CCS), the most practical method of them, plays a significant role. However, these methods have the disadvantage of the limits of geographical distribution and high possibility of re-emission into the atmosphere. Recently, ocean storage has been studied using Accelerated Weathering of Limestone (AWL), a technique for storing carbon dioxide in the ocean as an alternative to CCS, an underground storage. AWL is a method of converting carbon dioxide into concentrated water in the form of bicarbonate ion and discharging it to the ocean to dilute and store it. It does not cause re-emission to the atmosphere, and the discharged concentrated water increases the alkalinity of the ocean to prevent marine acidification. The objective of this study was to understand the behavior of DIC (Dissolved Inorganic Carbon) including carbon dioxide during the ocean discharge of bicarbonate ion concentrated water in AWL method. This study area was set near Ulleung-do where sufficient water depth and operational efficiency were secured. CORMIX model was used to calculate the material diffusion by submerged discharge using ship.

Recently, a new port reserves deep water depth for safe navigation and mooring, following the trend of larger ship building. Larger port facilities include long and huge breakwaters, and mainly adopt vertical type considering low construction cost. A vertical breakwater creates stem waves combining inclined incident waves and reflected waves, and this causes maneuvering difficulty to the passing vessels, and erosion of shoreline with additional damages to berthing facilities. Thus, in this study, the researchers have investigated the response of stem waves at the vertical breakwater near the entrance channel and applied numerical models, which are commonly used for the analysis of wave response at the harbor design. The basic equation composing models here adopted both the linear parabolic approximation adding the nonlinear dispersion relationship and nonlinear parabolic approximation adding a linear dispersion relationship. To analyze the applicability of both models, the research compared the numerical results with the existing hydraulic model results. The gap of serial breakwaters and aligned angles caused more complicated stem wave generation and secondary stem wave was found through the breakwater gap. Those analyzed results should be applied to ship handling simulation studies at the approaching channels, along with the mooring test.
