  • Cordyceps militaris, known as Dong-Chong-Xia-Cao, produces the most cordycepin among Cordyceps species and can be cultured artificially. For these reasons, C. militaris is widely used as herb or functional food in the East Asia. In this study, we developed a new strain of C. militaris that produces higher cordycepin content than parent strains through mating-based sexual reproduction. Twenty parent strains were collected and identified as C. militaris based on internal trasncrived spacer and rDNA sequences. Seven single spores of MAT 1-1 idiomorph and five single spores of MAT 1-2 idiomorph were isolated from 12 parent strains. When 35 combinations were mated on the brown rice medium with the isolated single spores, eight combinations formed a stroma with a normal perithecia and confirmed mated strains. High pressure liquid chromatography analysis showed that mated strain KSP8 produced the most cordycepin in all the media among all the tested strains. This result showed due to genetic recombination occurring during the sexual reproduction of C. militaris. The development of C. militaris strain with increased cordycepin content by this approach can help not only to generate new C. militaris strains, but also to contribute to the health food or medicine industry.

  • There are so many researches about the search method for the most compatible dispatching rule to a manufacturing system state. Most of researches select the dispatching rule using simulation results. This paper touches upon two research topics: the clustering method for manufacturing system states using simulation, and the search method for the most compatible dispatching rule to a manufacturing system state. The manufacturing system state variables are given to ART II neural network as input. The ART II neural network is trained to cluster the system state. After being trained, the ART II neural network classifies any system state as one state of some clustered states. The simulation results using clustered system state information and those of various dispatching rules are compared and the most compatible dispatching rule to the system state is defined. Finally there are made two knowledge bases. The simulation experiments are given to compare the proposed methods with other scheduling methods. The result shows the superiority of the proposed knowledge base.

  • The purpose of this study is to analyse the job activities of the H/D nurses andto develop their job activities. This study surveyed 222 H/D nurses' reports using a questionnaire which contained 101 questions about the nursing care contents of the H/D nursing and 7 questions about the characteristics of the H/D nurses who were working in the H/D rooms of the 80 hospitals and local clinics. H/D nurses checked for 6 days the frequency of the H/D job activities and the amount of time spent in each individual nursing content by the stop watch which had been provided. The data was gathered from Jan. 21, 1999 to Oct. 30, 1999 and analysed by descriptive statistics, F-test and Pearson's correlation r with SPSS program. The results are as follows:

  • The purpose of this study was to investigates the Autonomy and Job Satisfaction of the Nurses. The data was collected by distributing structured questionnaires to 317 nurses in 4 secondary hospitals located in Pusan, from July 1 to 31, 2010 and analyzed by t-test, ANOVA, Pearson correlation coefficient. The average autonomy level of nursing professionals was $135.30{\pm}8.04$ points. The average nurse's job satisfaction was $3.12{\pm}.35$ points. There was significant difference according to age, career and position in autonomy level of nursing professionals. There was significant difference according to age, marital status, career, position and monthly income in nurse's job satisfaction. The correlation between autonomy and job satisfaction of the nurses showed to be positively correlated at r = .426. Therefore, It is necessary to research into the methods to enhance the autonomy levels of nursing professionals and nurse's job satisfaction. It is necessary to develop education and policy programs for nurse's autonomy and nurse's job satisfaction.

  • For estimating discharge and pollution loads into the Yeongsan lake, a conceptual watershed model HSPF(Hydrological Simulation Program - Fortran) was applied to the Yeongsan River Basin. Various spatial data set including DEM, watershed boundaries and land uses were used to set up the model for the Yeongsan River Basin that was divided into 45 sub-basins. The model was calibrated and validated for the river discharges, SS, BOD, TN and TP concentrations against the data observed in 2011 at several monitoring stations. The simulation results show good agreement with the observed water flows($R^2$ = 0.46 - 0.97, NSE = 0.70 - 0.96). The simulated concentrations of SS, BOD, TN and TP are also in good agreement with the observed. The total freshwater discharge to the Yeongsan lake is estimated $2,406{\times}10^6m^3/year$ which the Jiseok and Hwangryoung stream contribute as much as 19%, 17% respectively. It is estimated that the total discharges to the Youngsan lake is SS 152,327 ton/year, BOD 15,721 ton/year, TN 10,071 ton/year, TP 563 ton/year. Both water and pollution loads are high in summer, particularly in July, when the monsoon season arrives at the Korean peninsula.

  • Importance-Performance Analysis(IPA) holds the assumption that the degree of physical fulfilment of quality attributes and the satisfaction of that attribute is linear. Therefore, IPA can be applied to the traditional one-dimensional attributes, not to other quality elements such as attractive or must-be attributes. To overcome this problem, several articles introduced methods that integrate IPA into the concept of two-dimensional quality. However, these articles are rather conceptual focusing on the differentiation of quality attributes depend on quality elements in IPA. To provide empirical evidence of the dependent relationship between attribute importance and satisfaction in IPA, this study introduces a weighted importance approach and provides validation method using Bacon's priority model, a regression model. For this, the current research investigates 23 quality attributes of TV set for the results of Kano's model, which are adopted from Kim et al., and conducted a survey of 118 university students for the results of the importance/satisfaction and improvement priority. The result of the proposed approach shows better result than those using the conventional way, based on R-square of the regression model.

  • This study aims to investigate the color characteristics and utilization of Amekaji fashion in the domestic casual market, with a focus on menswear. A total of 1,882 color data were extracted from 11 representative brands of Amekaji. This results of the study showed that PB, Bk, YR, and Y colors were highly utilized in the overall color, and dkg, g, ltg, and p tones were highly utilized. In particular, R color was highly utilized in the point color, as it was developed into six tones, including v, with high saturation. The analysis by the brand showed that the highest number of colors were extracted from 'Kapital', which is famous for its vintage-style patchwork and dyeing, and that 'PB' and 'Bk' were heavily utilized. By the item, PB colors were mainly utilized for denim, and shirts were diversified with 9 tones. W, a neutral color, was mainly used on clothing tops such as shirts, knits, and T-shirts. This study provides valuable insights into the color sensitivity of Amekaji fashion, which can be used as a useful resource for design development and product planning in the industry. As a future study, we suggest analysis of the utilization of Amekaji colors in the Korean men's casual market along with American and Japanese brands.
