The purpose of this study is to determine the most appropriate demand forecasting model among the existing demand forecasting techniques. So we analyzed and evaluated various existing demand forecasting model for their merits and demerits. We used Winters model and Box-Jenkins model for Statgraphics Package and Timeslab, and filtering for Fortran language in this study.
TQC와 TPM의 比較分析을 통한 효율적인 平價시스템 設定方案 : 中小企業을 中心으로 with special study on small - medium business
李相億 부천대학 1993 論文集 Vol.14 No.-
Small-medium business is becoming a foundation playing a role for economis stability band of dometic industrial society. But, our small-medium business is still forcing the bad situation in terms of productivity and quality when compared with big business company and has lots of empirical and traditioanal elements in their managemental technique. Recently, TQC has been becoming the motive power of small-medium company developement, but its level is still remains the QC-stage of inspection-intended. TPM that is highlighted recently contains a lot of problems in their driving method, so it is very necessary to make effective evaluation system for maximum effects through minimum costs in the bad environment of them. Thus, this study suggest effective evaluation system not only as a part of constitutional improvement of them but also as the elevation of productivity, quality, cost reduction by means of identifying the essence of TQC and TPM, and comparative analysis between them, for lasting the development and active facing against the situation of the business that change suddenly.

The purpose of this research is to present that improved tools and procedure for cost reduction. In this research. for the sake of this purpose. I explained that the tangible and intangible expectations were due to build of cost reduction modeling. The next projects of research are the effective distribution problems among the fixed cost and the variable cost. and are necessitated that the comparison research through actual proves to concretely make a factor the cost and the benefit in method of common cost distribution. Moreover for the most effective reduction of cost, it is indispensible that the research of subdividing and chaining the points of consideration.

This study was designed to examine the effects of histamine on gastric motility and its specificreceptor in the circular smooth muscle of the human gastric corpus. Histamine mainly produced tonicrelaxation in a concentration-dependent and reversible manner, although histamine enhanced contractilityin a minor portion of tissues tested. Histamine-induced tonic relaxation was nerve-insensitivebecause pretreatment with nerve blockers cocktail (NBC) did not inhibit relaxation. Additionally, K+channel blockers, such as tetraethylammonium (TEA), apamin (APA), and glibenclamide (Glib), hadno effect. However, NG-nitro-L-arginine methyl ester (L-NAME) and 1H-(1,2,4)oxadiazolo (4,3-A)quinoxalin-1-one (ODQ), an inhibitor of soluble guanylate cyclase (sGC), did inhibit histamine-inducedtonic relaxation. In particular, histamine-induced tonic relaxation was converted to tonic contractionby pretreatment with L-NAME. Ranitidine, the H2 receptor blocker, inhibited histamine-induced tonicrelaxation. These findings suggest that histamine produced relaxation in circular smooth muscle ofhuman gastric smooth muscle through H2 receptor and NO/sGC pathways.

The purpose of this study utilizes to basic data composing a fall exercise program development or studies gait pattern of old women forward on the basis of result that compare gait pattern with knee isokinetic strength, flexibility, balance experience old women group. Subject of this study selected old women 48 people that independent life among old women welfare hall member that experiences a fall more than 2 times for 3 years, more than 1 times for 1 year among 65~75 year old. From a fall musculoskeletal injury chose 30 people for study subject person exempting old women who among 68 from a fall women of experiences except 48 people, measurement of 15 old women and that medical history report of skeletal system disease was is omitted Measuredquestionnaire method, knee isokinetic strength of knee joint to measure of knee isokinetic strength. Evaluated static balance and dynamic balance to evaluate balance. Measured ROM flexion of hip joint, flexion of knee joint and dorsi flexion plantar flexion of ankle joint to use measuring instrument sit & reach and goniometer for oftness examination. Gait analysis used measurement equipment that do as can measure variables that is spatial and is temporal of walk automatically as if look at a foot under. The results of this study were knee isokinetic strength isnon-significant in two groups. But Non-faller group was superior knee isokinetic strength strength than faller group. Balance is non-significant in two groups. Dynamic balance is non-faller group than faller group time short. Non-faller group stood for a longer time than faller group in static balance. Gait pattern is non-significant in two groups. Non-faller group was more superior than faller group in variable temporal. Non-faller group was wider than faller group in base width variable. Conclusively, knee isokinetic strength, flexibility, balance and gait patterns is non-significant in two groups. The reason old women welfare hall users all life independent possible, and old women welfare hall by is old women who physical activity is users more than 2 day on a week. Next investigators are thought that need study about physical fitness, functional fitness and gait pattern because physical activity difficult old women and various groups old women.
