朴明圭 明知大學校 産業技術硏究所 1996 産業技術硏究所論文集 Vol.15 No.-

In this study, a traditional concept of sampling inspection plan for the quality assurance system is extended to a consideration of economic aspects in total production system by representing and analyzing the effects between proceeding / succeeding production process including inspection. This approach recognizes that the decision to be made at one manufacturing process (or assembly process) determine not only the cost and the average outgoing quality level of that process but also the input parameters of the cost and the incoming quality to the succeeding process. By analyzing the effects of the average incoming and outgoing quality, manufacturing/assembly quality level and sampling inspection plan on the production system, mathematical models and solution technique to minimize the total production cost for a single product manufacturing system with specked average outgoing quality limit(AOQL) are suggested.

PGE₁is an endogenous substance of potent vasodialator as well as inhibitor of platelet aggregation. It has been used therapeutically in peripheral arterial occlusive disease and impotence. Intracavernous injection of PGE₁ for erectile dysfunction has been established for several years as a treatment option for erectile dysfunction of diverse etiologies, but this mode of administration is limited by penile discomfort, pain at the injection site, inconvenience and noncompliance. As the matter of worse, the β-hydroxy moiety of PGE₁is extremely susceptile to dehydration in solution to give inactive PGA₁ and PGB₁. For the improvement of stability, rapid absorption at action site and the convenience of application, PGE₁was formulated as urethral suppositories of three types of formulations, such as PEG, witepsol, and the mixture of PEG and witepsol. The stability test of PGE₁and the release test in urinary suppositories were performed. Futhermore, the effect fo enhancers and vehicle composition on the penetration of PGE₁through excised rat skin was evaluated by permeability coefficient and enhancement ratio.

본 연구는 스트레스 반응을 측정하는 스트레스 반응 척도 설문지(Symptoms of Stress: SOS)를 이용한 횡단적 연구로서 심신수련의 하나인 기수련이 스트레스 반응에 미치는 효과를 살펴보았다. 72명의 건강한 정상인과 180명의 기수련자를 대상으로 하여 조사하였으며, 기수련자들은 수련기간에 따라 초급군(1-4개월; 64명), 중급군(5-12개월; 50명), 고급군(1년 이상; 66명)로 나누었다. 실험결과 1년 이상 수련한 기수련자들이 말초혈관 증상군, 심폐 증상군, 중추신경계 증상군, 위장계증상군, 습관적 행동 형태군, 우울 증상군, 불안증상군등의 스트레스 반응 하위척도에서 대조군에 비해 통계적으로 유의하게 감소하였다. 전체 스트레스 값은 대조군에 비해 기수련자 집단이 아주 낮았으며 수련기간이 길수록 감소하였다. 이러한 결과는 기수련이 스트레스 중재와 스트레스 증상을 줄이는데 효과가 있음을 나타낸다. We examined the effects of Qi-training, one of Korean traditional psychosomatic training, on stress coping ability by cross-sectional investigation with inventory of symptoms of stress (SOS). Four types of groups- normal healthy (n-74), three groups of Qi-trainees (group primary level: subjects with Qi-training for 1-4months, n=64; middle level: 5-12 months, n=50; high level: more than 12 months, n=66) participated in this study, Qi-trainees with over 1 year training had significantly lower scores in all SOS subscales compared to controls. Total stress scores of Qi-trainee groups were substantially lower than controls and further reduction with larger training periods. These results suggest Qi-training is effective in stress management and decreasing symptoms of stress

The present experiments for positive and negative walking behavior were carried out with the popula-tions of Drosophila melanogaster, collected from eight localities of the Korean peninsula. The behavior was examined by means of photo-varicolored ladyrinth apparatus. The realized heritabi-lity for males on difference in photo-preference was estimated to the about 3.4∼9.4% for the positivewalking behavior, and that for negative behavior was about 4.2~8.6% . The heritability for femaleswas estimated to be about 1.0∼12.6% for the positive walking behavior, and that for negative behaviorwas about 2.4∼9.5%. Walking score for males and females in inland was estimated to be about 2,00~3,00 for the positivewalking behavior, and that for negative behavior was about 1,00∼1.25. Walking score for males and females on the coast was estimated to be about 2.25~2.90 for the positivewalking behavior, and that for negative behavior was about 1.16∼1.50. In conclusion, the walking behavior of photo-varicolored preference showed that it prefered bluelight color best, second; yellow, third; red, and last; dark. It seems resonable to assume that thewalking behavior is possibly controlled by a major gene.

Bond strength of fiber reinforced polymer(FRP) Rope was experimentally investigated in this study and compared to that of steel rebars. A total of 20 pullout specimens and 5 concrete beams with four type of FRP Ropes and two type of steel rebars, respectively, were tested. The key parameters are the diameter, outer surface of FRP Rope and concrete strength. Two nominal diameters of FRP Rope and steel rebars, namely, 10 and 16mm and one embedment length, 25cm were used. Results of the tests indicated that the applied tensile load approached the tensile strength of rebars and the FRP Ropes showed lower bond strength values compared to steel rebars. The bond strength was calculated according to the relevant ACI Code requirements for steel rebars in concrete.

Pelvic actinomycosis is a chronic granulomatous suppurative disease caused by an anaerobic grampositive organism Actinomyces israelii. It is com-monly associated with an intrauterine device(IUD) and can mimick pelvic or intra-abdominal malignant neoplasm. Ureteral obstruction leading to hydronephrosis is a rare complication of tubo-ovarian abscess. We experienced a case of hydronephrosis as a complication of pelvic actinomycotic abscess. The patient was a 46-year-old women presenting with fever and right flank pain. Leukocytosis and pyuria were present and a hydronephrosis was diagnosed by intravenous pyelography. Ultrasonography and a computerised tomography revealed a mass in right adnexum compressing the right ureter. Removal of retroperitoneal abscess and salphingo-oophorectomy were done and the diagnosis of actinomycosis was made by pathologic finding of resected mass. Postoperatively, the patient was treated with second-generation cephalosporin successfully. (Korean J Nephrol 2002;21(2):337-340)

조용욱,박명규 明知大學校 産業技術硏究所 1999 産業技術硏究所論文集 Vol.18 No.-

Taguchi's parameter design is to determine optimal settings of design parameters of a product or a process such that the characteristics of a product exhibit small variabilities around their target values. the critical problem in dealing with mutiple characteristics is how to compromise the conflicts among the selected levels of the design parameters for each individual characteristic. In this paper, Methodology using SN ratio optimized by univariate technique is proposed and a parameter design procedure to achive the optimal compromise among several different response variables is developed. one new case studies are solved by the proposed method and the results are compared with ones by the sum of SN ratios, the expected weighted loss, the desirability function, and EXTOPSIS model.

자동화 생산 시스템에서의 생산셀 설계와 셀 배치계획을 위한 통합모델

This paper is concerned with problem of manufacturing cell design and cell layout planning in automated manufacturing system design. To solve this problem the proposed model incorporates relevant manufacturing factors such as workload and cell size. Based on those information, to form the manufacturing cell, correlation similarity coefficient(CSC) among machines are calculated and a pair of machines that has the highest value of CSC is assigned to a machine cell. Repeat the above steps until the adequate manufacturing cells are obtained. Because the obtained cellular structure for the manufacturing system design in the previous stage does not give the layout of the cells on the site directly, it is important to determine the adequate cell layout. For the cell layout planning, the adjacent relationship among cells are determined on the basis of the degree of interference among cells which is evaluated by the volume of the intercel1ular movements among cells. The relationship obtained by this procedure determines the configuration of the cell layout. Finally, a system is improved to increase the efficiency of a proposed model. The proposed model and system are illustrated by numerical example.
