연안 양식어장의 정보 관리에 실용적인 지리정보시스템(GIS)을 적용함으로써 어업종사자와 연안 관리자에게 실현 가능한 관리방안을 제시하고 수산업 발전을 위한 유연한 의사결정의 기반을 마련하고자 하였다. 연안 양식어장의 효과적 관리는 경제적 실행 가능성과 운영비용에 영향을 미치며 양식 대상생물의 생산 및 사망률과도 관계가 있으므로 매우 중요하다. GIS는 양식어장 정보의 효율적인 관리도구로서 개인 및 공공분야에서 폭넓게 사용되고 있으며 해양수산 관련분야에서도 활발히 적용되고 있다 본 연구에서는 진해만을 대상으로 연안 양식장 자료의 3차원 가시화 모듈을 구축하였다. This paper illustrates some practical geographic information system (GIS) applications for aiding fishery managers and coastal area planners in analysing the likely control scheme of coastal farming areas, and in providing a flexible framework for decision making on fishery development and zoning issues. The effective management of marine farming operation is vitally important since it can greatly influence economic availability by determining capital outlay and by affecting running costs, rates of productions and mortality factors. GIS has been widely adopted elsewhere as a potent management tool in both the private and public sectors. GIS is now being extensively adopted in marine-associated activities. Here, we have used GeoMania v2. 5 GIS software and its 3D Analyst extension module to visualize marine farming areas data that were collected around the Jinhae bay.
Ontology of time and relational tense

This paper reviews some discussion on the ontology of time and investigates relevant issues of tense logic and temporal relations. It seems that most of modern tense theories are in B-theoretic terms of time, which are later/earlier than. Reichenbach’s tense theory clearly shows such characterization of tense, which is intuitive and influential, and it may be tied to our conception of time.

Cerebral vasospasm following aneurysmal subarachnoid hemorrhage is one of the most important causes of cerebral ischemia. Hypervolemic hypertension and hemodilution have been reported to be an effective method for prevention and treatment for cerebral ischemia secondary to cerebral vasospasm. We compared the volume expanding effects between normal saline(20 cases), 10% pentastarch(20 cases) and dextran(20 cases) after clipping of cerebral aneurysm in the patients with subarachnoid hemorrhage and the incidence of vasospasm by transcranial doppler(TCD) postoperatively. The results were as follows ; 1) The total amount of infused volume in pentastarch and dextran group were 310±46ml, 438 ±262ml respectively,and were significantly smaller than normal saline group, 1078±187ml.(p$lt;0.05) 2) Plasma osmolality was increased by 10 mOsm/kg in pentastarch group, but statistically insignificant. 3) Hematocrit value was decreased significantly in pentastarch and dextran group from 34.9±1.03%, 34.8±1,4% to 31.6±1.38%, 39% respectively.(p$lt;0.05) 4) Cases over 80cm/sec by TCD were 3 in normal saline, 2 in pentastarch, and 2 in dextran group. We conclude that 10% pentastareh could be used as an effective blood volume expander after cerebral aneurysm clipping.

국내 대표 관광지인 강원도는 관광수요가 일부 지역에만 편중되어 있어 지역별로 다른 관광추이를 보인다. 따라서 각 지자체의 관광 활성화 방안 수립과 지역간 균형발전을 위해 각 지역의 관광 특성을 파악하고, 연도별 관광패턴을 비교하는 것이 중요하다. 본 논문에서는 최근 4년간의 강원도 관광 자료를 이용하여 지역을 군집화하고, 군집별 관광패턴을 Jeon 등 (2021)이 제안한 비유클리디안 가법모형으로 분석하였다. 이때, 연령대에 따른 방문자 수 비율과 방문지 유형에 따른 내비게이션 검색 수 비율을 공변량으로 하고, 업종별로 구분된 관광지출액 비율을 반응 변수로 하였다. 모형의 추정을 위해 평활역접합 방법과 성분별 띠폭 선택법을 이용하였다. 그리고 삼각 도표를 통해 추정된 모형을 시각화하고, 군집별로 적합 오차에 대한 예측 오차 비율을 비교하여 연도별 관광패턴 변화를 확인하였다. Gangwon-do is one of Korea's most popular tourist destinations, with varying tourism demands and trends across its subregions. It is crucial to identify the characteristics of tourism in each area and compare the tourism patterns over time to devise policies that revitalize tourism in each local government and promote balanced development across regions. In this paper, we classify the regions in Gangwon-do based on tourism data from the last four years and analyze the tourism pattern of each region using the non-Euclidean additive model proposed by Jeon et al. (2021). The model incorporates the proportions of visitors by age groups and the proportions of navigation searches by destination types as two covariates, and the proportions of tourism expenditure types as a response variable. We estimate the model using the smooth-backfitting method and coordinate-wise bandwidth selection. The results are visualized in ternary plots, and changes in tourism patterns over time are analyzed by comparing the ratios of prediction errors to fitting errors.
