The ROK TRANSCOM and Army Logistics Command have established wartime overland transportation plans. They have to mobilize several wartime overland transportation troops in order to meet the wartime transportation requirement. But there are some uncertainties in the process of transportation such as the number of vehicles to mobilize, the vehicle utilization factor, and round trip time. Here, we established two models. One is the simulation model to evaluate the transportation capability considering uncertain factors. The simulation model is executed with two scenarios and then the results are analyzed through a sensitivity analysis. The other model is the regression model to analyze the effects of transportation factors toward capability.

Enzymatic hydrolysis of lignocellulosic biomass by various commercial enzymes has been studied. The commercial cellulases used in this study showed different CMCase and β-glucosidase activities but have similar FPase activities. CMCase was found to play a key role for the enzymatic hydrolysis of lignocellulosic biomass which contains inert material such as hemicellulose and lignin. The β-glucosidase inhibition by lignin was the most remarkable for Celluclast which has the lowest p-glucosidase activity. FPase activity could not represent the capability to hydrolyze the lignocellulosic biomass.

목적: 단백뇨 질환에서 볼 수 있는 사구체 상피세포(glomerular epithelial cells, GEpC) 족돌기(foot process)의 병리학적 변화에 있어서 GEpC사이의 세극막(slit diaphragm)과 세포골격을 연결하는 ZO-1 단백의 당뇨조건에 따른 변화를 알아보고자 하였다. 방법: 백서 GEpC을 배양하고 고농도의 당과 후기당화합물(advanced glycosylation enduroducts, AGE)를 적용하여 당뇨병 환경에 가까운 조건을 설정한 후, ZO-1 단백양은 Western 분석으로, 분포 변화는 공초점 현미경으로, 유전자 표현의 변화는 RT-PCR로 관찰하였다. 실험군은 당의 농도를 5 또는 30 mM로, AGE와 BSA를 첨가하고 osmotic control로서 당 5 mM에 mannitol 25 M을 섞은 것을 조합하여 A5, A30, B5, B30, Aosm로 하였다. 결과: 공초점 현미경 상 ZO-1은 정상적인 환경인 B5에서 B30, A5, 가장 병적인 A30 환경으로 진행할수록 세포질의 바깥에서 안쪽으로 이동하는 양상을 보였다. ZO-1 단백양은 B5 결과를 대조군으로 비교하여 당을 첨가한 B30에서 11.1%, AGE를 추가한 조건인 A5에서 2.3% 감소하였나 통계적 유의성은 없었고, 당과 AGE가 동시에 첨가된 A30에서는 19.0%의 유의한 감소를 보였다. mRNA의 발현도 A30에서만 12.0%의 의의 있는 감소를 보였다. 이러한 단백질과 mRNA의 감소 소견은 osmotic control (Aosm)에서는 관찰할 수 없었다. 결론: 고농도의 당과 AGE에 의한 GEpC의 ZO-1의 분포 변화와 유전자 수준에서의 억제로 단백의 생성 감소를 초래함으로써, 장기간 당뇨 환경체서 족돌기의 형태학적 변화를 설명할 수 있으며, 추후 이의 변화 기전에 대한 연구가 필요할 것으로 사료된다.

Objectives: This study (a) investigated the rate of smoking cessation sucess for current male smokers, and (b) identified the factors that are associated with the smoking cessation success. Methods: Data were collected from four follow-up surveys of 700 current male smokers. The follow-up period was from December 2004 to June 2005. Success of smoking cessation was defined as "maintaining a smoking cessation status for six months". The demographic and socioeconomic factors included age, the household income level and, occupation. The smoking behavioral factors were composed of the amount of smoking, the duration of smoking, the age of initiating smoking, the willingness to quit, the frequency of trying to quit smoking and the smoker's attitude toward the anti-smoking policies. Results: The proportion of quitters increased from 6.6% to 11.0% during the follow-up period. The majority of quitters answered that the increase of tobacco price acted as cue to achieve smoking cessation. The age-standardized experience and success rate of smoking cessation were 16.0% (95% C.I.=13.0% to, 19.0%) and 4.5% (95% C.I.=3.0% to, 6.0%), respectively. On the multivariate analysis, success for smoking cessation was associated with the willingness to quit smoking, low prior tobacco consumption, and agreement on the tobacco price increase. Conclusions: The results of this study suggest that the recent anti-smoking policies provided an opportunity to quit smoking. The results of this study can be used to establish evidence for further anti-smoking policies.
