      • (s, S) 예비품재고모형의 운용비용에 관한 연구

        신주환,박영택 成均館大學校 科學技術硏究所 1990 論文集 Vol.41 No.1

        This paper deals with a continuous review (s, S) spare-part inventory model for multiple operating units, in which stock depletion arises not from external market demand but from internal demand resulting from failures of the units in use. In this paper, we consider the following situation. N units having identical exponential lifetimes are operating simultaneously and the replenishment lead time is general. In the (s, S) spare-part inventory model, a quantity Q =S-s is ordered each time the inventory level reaches the reorder point s. Average annual cost of operating the inventory system is derived under the assumption that there is never more than a single order outstanding.

      • 산업훈련 프로그램 개발에 관한 연구 : 가구 판매사원 훈련 프로그램

        김신자,주영주,이광희 이화여자대학교 한국문화연구원 1995 韓國文化硏究院 論叢 Vol.66 No.1-3

        Rapid development of modern society demands incessant cultivation of new knowledge, function and skills. Even if a firm succeeds in securing qualified manpower, continuous training is imperative for the company to adapt to rapidly changing consumer tastes and business environment. Many of large size firms in Korea began to realize the importance of training programs of their employees. Therefore, they are developing their own programs and willing to spend a large portion of their budget to human resource development. Most of small and medium size firms, however, have not understood the necessity of training program of their won employees. Even if some of them want to make an investment on training their own employees. They could not find the right model suitable to small and medium size firms. Therefore, without analyzing the relevance for the model to their situation, they are forced to use the model mainly designed for large scale firms. After brief introduction, in chapter 2, we analyze the needs for new training programs and introduce well-known training models. We cannot, however, apply the models to the furniture industry without major modification to reflect the main features of furniture industry. Therefore, in chapter 3, we develop new graining programs which consist of four steps of need assessment, design, development, formative evaluation and which are more suitable to furniture industry. We do need assessments in four areas-business needs analysis, job analysis, task analysis, and content analyses. In the second step of design, we prepare program specification and road map. In the third step of development, we produce manuals, transparencies, slides and audio pates for the trainee. In the final step, we perform formative evaluation. In the last chapter, after summarizing our research, we make some suggestion on effective training programs for small and medium size firms on the basis of our study.

        시판김치 중 유해세균의 조사

        신선미,박주연,김은정,한영숙 한국조리과학회 2005 한국식품조리과학회지 Vol.21 No.2

        Three different commercial Kimchi industry-made packaged, department store-made and ordinary market-made were analyzed for their pH, acidity and microbiological characteristics including certain harmful bacteria on selective media during a storage-fermentation period of 7 days at 2℃ or 20℃. The p11 of all the Kimchi samples wasdecreased from 5.85 to 3.82 and their total acidities increased from 0.2 to 1.18 as the fermentation continued during the storage-fermentation. E. call and Salmonella sp. of 0~1101 cfu/mL were found in the industry-made Kimchi just after purchase time. As the storage-fermentation proceeded, the viable numbers of these bacteria had been reduced in all Kimchi samples tested and no bacteria were detected after 5 days at 2℃ and 2 days at. 20℃., respectively. On the other hand, a range of 7.9102℃2.9103 cfu/mL of Staphylococcussp. was detected in the department store-made and ordinary market-made Kimchi samples at the purchase time, which was higher than that of the industry-made Kimchi, and this range wasn't reduced (luring storage-fermentation. The viable number of yeasts in the market-made Kimchi was 2.1103 cfu/mL, These results suggest that some commercial Kimchis were contaminated by some harmful bacteria and that a portion of these bacteria remained alive in the Kimchi, even with high acidity during the edible period.

      • 膜分離에 의한 海水의 淡水化에 관한 硏究

        申盛義,李性琪,崔炯一,申大允,金永範,李抵憲,姜永周 조선대학교 환경연구소 1989 環境公害硏究 Vol.6 No.-

        In this study, we made investigation into water permeation, solute separation, concentration and Na^(+), K^(+), Mg^(2+), Ca^(2+), Cl^(-), SO^(2)_(4)-, HCO^(-)_(3) ions separation of seawater by the revers osmosis process using a suitable semipermeable membrane. The different thickness of membranes were prepared. On heat treatment, temperature was 80℃ and thier effects were also investigated. The flat single module system was made to be capable of treating feed solution at 200-2000cc/min and 120 atm. The experimental results can be summerized as follows: 1) As the effective operating pressure increased, permeability of pure water proportionally increased. 2) As the exposure period of the manufactured membrane in air increased, permeation rate increased, but as the thickness of the membrane increased, permeation rate decreased. 3) The capacity for being reproductive of the manufactured membrane (CA: 30wt%, Formamide: 45wt%, Acetone: 25wt%) in their performance was less than 10-30% and agreed with that reported in the literature. 4) We could separated about 85-95% of salt ion in seawater using a flat single module system.

        김치 재료 methanol 추출물이 식품유해 미생물에 미치는 항균효과

        신선미,박주연,한영숙 한국조리과학회 2005 한국식품조리과학회지 Vol.21 No.1

        This study was carried out to determine the inhibitory effect of methanol extract from kimchi ingredients against Salmonella pphimurium, Listeria monocvtoenes, Staphylococcus aureus, and Esherichia toll which are pathogenic microorganisms and Aspergillus sp, Penicillium sp. Antimicrobial activity of methanol extracts was tested against bacteria by paper disc method. Antifungal activity of methanol extracts was shown by hyphal growth inhibition ratio. The methanol extracts from all materials were effective against E. coil among them. And the antimicrobial activity of the methanol extracts from ginger and onion were lower than the others. The antifimgal activity of the methanol extracts from radish, ginger, and garlic were effective against Aspergillus sp. and Penicillium sp. In the result of identifying antimicrobial effect rate, the methanol extracts from red pepper and radish had more than 40% against S. nphimurium and more than 30% against K coll. Also the methanol extracts front onion had an high inhibitory effect rate of more than 50% against S. tvphi,nurium and that from garlic had more than 60% against S. aureus. The minimum inhibitory concentration(MIC) of red pepper was examined 500 pg/mL against L monocytogenes. This value was the lowest among the others.

        자기효능 정보자원 프로그램이 관상동맥 질환 환자의 지각된 자기효능감과 자가간호행위에 미치는 효과

        신주영,김순용 성인간호학회 2002 성인간호학회지 Vol.14 No.1

        Purpose: This study was conducted to investigate whether a self-efficacy information resources program based on the self-efficacy theory of Bandura (1986) would increase self-efficacy and self-care in patients with CAD. Method: The study was a one group, pretest-posttest pre-experimental design research. The Self-Efficacy Information Resources program was composed of a video tape program and a telephone coaching program and based on vicarious experiences and verbal persuation. The Program was used as an experimental treatment from February 27. to May 27, 1999. Twenty patients participated from a university hospital located in Seoul. Three days later after a pretest the telephone coaching program was given. It was repeated weekly during a 3 week period. At the end of this period post-test data were collected by mail. Data were analyzed with a random permutation test using SAS program. Result: 1) Scores on self-efficacy after the Self-Efficacy Information Resources Program were significantly higher than before the program (p=0.06). 2) Scores on self-care after the Program were significantly higher (subjective self-care. p=0.0005; objective self-care, p=0.0002) than before the program. Conclusion: The Program was found to be an effective nursing intervention for increasing self-efficacy and self-care. When nurses who care for CAD patients plan to increase their patients' self care ability, they should always consider the concept of self-efficacy.

      • 풍진항체 검사법의 신뢰도에 관한 연구 : Comparison of the Methods between the Abbott RUBAZYME kit and the Abboutt IMx Automated Analyzer

        신영전,최보율,최은주,박항배 한양대학교 의과대학 1995 한양의대 학술지 Vol.15 No.2

        Abbott Rubazyme and Abbott IMx, which are most used to prevent Rubella IgG and IgM thesedays, were evaluated for their reliability. Both methods were tested on 305 women, 287 and 18 number of each pregnant and non-pregnant women, in Yangpyong county from March 1993 through September 1993. In addition, they had 14. 3 weeks of pregnant period and 25.8 of average age. It appeared that there was a significant correlation between the titers of Rubazyme and IMx for Rubella IgG (Coefficient Correlation 0.6167, p=0.000) but not for IgM(C. C. 0.0668, p=0.245). Additionally, the correlation coefficient of the two methods for IgG titer of 1st and 4th quartile, 0.6829, p=0.000, were higher than that of 2nd and 3rd, 0.4600, p=0.000, So does IgM : 0.1081, p=0.181 for ist and 4th quartile and 0.0230, p=0.780 for 2nd and 3rd quartile. The agreement rate of positivity was 92.5% for IgG and 99.0% for IgM. The kappa index for IgG was 0.51338. The agreement point of titer, where the number of a people who showed positivity for IgG in IMx test and that in Rubazyme kit test became equal, was 31.3 IU/ml, which was 315% of the original point, 9.949 IU/ml. The agreement rate of both tests for 1gG was decreased to 92.13% but the kappa index was increased to 0.66869 in rasing cut off point of the IMx up to 31.3 IU/ml. Abbott Rubazyme and Abbott IMx tests play important roles in determining the infection of pregnant women and even the prevention of deformation of child and artificial abortion. However, since these two methods turns out not to be reliable to be used through this experiment, physicians should examine the reliability of both methods, and even the possibility of technical errors of them before actual use.
