본 논문에서는 인천남동공단 물류공동화 시범사업에 참여하는 기업과 비참여 기업을 대상으로 설문조사를 통해 물류공동화의 중요도와 만족도를 조사하였다. 물류공동화의 효과와 장애요인, 물류공동화 참여를 결정하게 하는 주요 요인에 대해 연구하였다. 설문조사 결과를 근거로 물류공동화 참여변수의 관계를 회귀분석, 교차분석과 t검정을 통해 물류공동화 참여효과를 분석 하였다. 특히 물류공동화 중요도 및 만족도를 분석한 결과 물류공동화는 인적, 물적 자원과 시간, 비용절감 및 고객서비스향상, 환경개선, 교통체증 해소, 공동 수배송을 통해 적재효율이 높아져 운송비 절감을 도모하고 있는 것으로 분석되었다. 물류공동화 시행으로 물류자원의 효율적 활용을 통한 물류비절감, 안정적인 서비스제공 등 기업경쟁력 강화측면에서 긍정적인 영향을 미치는 것으로 분석되었다. This study examined the importance of and satisfaction with integrated logistics center by surveying companies that are participating or not participating in the Incheon Namdong Industrial Complex's integrated logistics center project. It particularly studied the effects and obstacles of integrated logistics and the major factors that encourage companies' participation. Based on the results of the survey, the variables affecting companies' participation in integrated logistics were analyzed by regression analysis, crosstabulation analysis, and t-test. Then, IPA analysis was applied to derive integrated logistics center's relative maintenance factors, excess investment factors, improvement factors, and focused improvement factors. In result of the analysis, it was found that integrated logistics saves freight cost by improving loading efficiency to save human and material resources, time, and cost, improve customer services and work environment, and solve traffic congestion problems. It was found that integrated logistics system has positive effects on companies by securing efficient use of logistics resources to save time and provide reliable services.

In prenatal diagnosis of neural tube defects, maternal serum α-fetoprotein (MSAFP) level in second trimester is used as a screening test. However, it shows low sensitivity with high false positive rate. Also, α-fetoprotein and acetylcholinesterase in amniotic fluid through amniocentesis is used, but it is an invasive technique with low sensitivity. Recently, due to improved prenatal sonography, typical sonographic findings of spina bifida are reported and contributed to early diagnosis and detection of possible co-existing abnormalities. We report a case of spina bifida detected at 21 weeks of pregnancy by prenatal sonograph at our institution with a brief review of literature.

Plant pipe has a fatigue life which is induced by repeated stress come from the variation of temperature and pressure. To avoid the fatigue crack of plant pipe which is produced by long term repeated stress, plant operator has to limit the amount of operating transient. This paper introduced the study result about discrimination methodology of plant transient by using the fuzzy pattern recognition. As result of applying the fuzzy pattern recognition to actual plant operation data, it is confirmed that fuzzy pattern recognition methodology can be useful for the comparison of similarity for the transients of similar output but has different time pattern.
유기티탄늄 화합물을 이용한 Phthalide 유도체 합성

o -N,N-Diisopropylbenzamidotitaniumtriisopropoxide was easily prepared through transmetallation of the corresponding o -N,N-dialkylbenzamidolithium. These two organometalic compounds react smoothly with carbonyl compounds to alcohols, which were by heating converted to phthalides. In these reactions organotitanium reagents led to better yield than organolithium reagents and showed absolute aldehyde-selectivity in competive reactions between aldehyde-ketone.
