In an effort to optimize tissue culture responses of zoysiagrass (Zoysia japonica Steud.) for genetic transformation, factors affecting callus induction and plant regeneration were investigated. MS medium containing 3 ㎎/L 2,4-D was optimal for embryogenic callus induction from mature seed. The plant regeneration frequency of 73.3% was observed when embryogenic calli induced in this medium were transferred to N6 medium supplemented with 0.1 ㎎/L 2,4-D and 5 ㎎/L BA. Among several basic media, MS and N6 medium were optimal for callus induction and plant regeneration, respectively. Regenerated plants were grown normally when shoots transplanted to the soil. A rapid and efficient plant regeneration system established in this study will be useful for molecular breeding of turfgrass through genetic transformation.

Afferent loop syndrome is an uncommon complication of a gastrectomy and Billroth Ⅱ reconstruction. It may cause symtoms at any time from the first postoperative day to many years after the gastrectomy. Afferent loop syndrome is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate afferent loop syndrome from other cause of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing afferent loop syndrome. We experienced one case of chronic afferent loop syndrome with acute pancreatitis. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. We report this case with a review of relevant literatures.

The present study investigated the habitats of Korean fir trees (Abies koreana E. H. Wilson) on Mt. Baekwun (Baekwun-san), determined the current distribution, quantified the contribution of biological and nonbiological environmental factors affecting the distribution, derived actual and potential habitats, presented a plan for the establishment of protected areas, applied RCP 8.5 climate change scenario to analyze the effects of climate change on the future distribution of Korean fir trees, and predicted future potential habitats. According to the results of the study, 3,325 Korean fir trees (DBH >= 2.5 cm) inhabited Mt. Baekwun, and their distribution area was approximately 150 ha. Populations of Korean fir trees were confirmed to exist at an altitude of 900 m above sea level and were distributed up to 1,200 m. Based on potential distribution, areas appropriate for habitation by Korean fir trees were analyzed to be 450 ha, three times the current distribution area, with a focus on Sang Peak (Sang-bong), Eokbul Peak (Eokbul-bong), Ddari Peak (Ddari-bong), and Dosol Peak (Dosol-bong). The forest stands near Sang Peak, the main peak, were evaluated as those with the most appropriate potential for the habitation of Korean fir trees, and populations of the trees tended to prefer the northern slope rather than the southern slope. When climate change scenario RCP 8.5 was applied and future potential distribution was analyzed, the habitats were expected to decrease in area to 20 ha by 2050, with a focus on Sang Peak, and areas appropriate for habitation were predicted not to exist by 2080. Judging from such results, as global warming accelerates, the habitats of Korean fir trees are clearly expected to move from lowlands to highlands.

이상완,남현우,윤연근 한국경영과학회 1997 韓國經營科學會誌 Vol.22 No.2

In general, two types of fuzziness of human judgements should be incorporated in multiobjective programming problems. One is the expert's ambiguous understanding of the nature of the parameters in the problem formulation process and the other is the fuzzy goals of the decision maker for each of the objective functions. In this paper, we present a new interactive fuzzy approach for obtaing the satisficing solution which efficiently reflect both types of fuzziness. An illustrative numerical example nonlinear programming problems with fuzzy parameters is demonstrated along with the corresponding computer outputs.

이근상,고덕구,조기성 한국지리정보학회 2003 한국지리정보학회지 Vol.6 No.3

본 연구에서는 최근 도시계획, 수자원 및 방재 분야에서 높은 관심을 가지고 연구중인 항공레이저측량기법을 활용하여 시가지의 건축밀도를 평가하였다. 먼저, 레이저스캐너인 LiDAR(light detection and ranging)로 취득한 표고자료로부터 DEM(digital elevation model)과 DSM(digital surface model)을 구축하였으며, 건물의 높이를 계산하기 위해 DEM에는 ZONALMEAN 필터, DSM에는 ZONALMAJORITY 필터를 적용하였다. 필터링 과정으로부터 계산한 층수와 현지조사의 층수를 비교한 결과 표준오차 ±0.199층을 확보할 수 있었다. 또한 건물 연면적 레이어와 구획레이어를 중첩하여 통계분석함으로서 도시 구획별 용적률을 제시할 수 있었다. 항공레이저측량 자료를 이용하여 계산한 용적률과 현지조사로부터 계산한 용적률의 비교 결과, 용적률의 표준오차를 ±2.68%로 확보할 수 있었다. 따라서, 항공레이저측량 자료는 향후 토지이용계획을 수립하는 의사결정자에게 매우 유용한 자료를 제공해 줄 것으로 기대한다. This study evaluated the architectural density of urban district using airborne laser scanning(ALS) that is a method used in urban planning, water resources and disaster prevention with high interest recently. First, digital elevation model(DEM) and digital surface model(DSM) was constructed from Light detection and ranging(LiDAR). For getting the height of building, ZONALMEAN filter was used in DEM and ZONALMAJORITY filter was used in DSM. This study compared the floor from filtering with the floor from survey and got standard error, which is ±0.199 floor. Also, through the overlay and statistical analysis of total-area layer and zone layer, we could present floor area ratio by zone. As a result of comparison with floor area ratio between airborne laser scanning data and survey data, the standard error of flor area ratio shows ±2.68%. Therefore, we expect that airborne laser scanning data can be a very efficient source to decision makers who set up landuse plan in near future.
