  • During the past few years, the productivity has been considered as one of the most important aims in developing softwares. Many practitioners and theorists are trying reuse ready made codes to increase the productivity of software development and the quality of their products. This paper introduces our experiences in developing a highly reusable class library and its reusing environment for building a database interface application. And the concepts, Structured Multi-Library and Dual Views of Class Inheritance, are also suggested, which consist our main conceptual framework in our work. Details in implementation are discussed in brief at the end.

  • Purpose: This study was done to identify the effects of the BeHaS exercise program consisting of exercise, education, and cognitive supports on the hand strength, depression and life satisfaction in institutionalized elderly people with CVA. Method: A quasi-experimental design with an experimental group (n=18) and a control group (n=18) was used. The elders in the experimental group participated in the program once a week for eight weeks. Data were analyzed using descriptive statistics, Chi-square and t-test with SPSS/Win 18.0. Results: Hypothesis 1 was supported as the hand strength of the elders in experimental group significantly increased compared to those in the control group. Hypothesis 2 was also supported as depression scores for elders in the experimental group significantly decreased compared to those in the control group. Hypothesis 3 was supported as life satisfaction scores for elders in the experimental group significantly increased compared to those in the control group. Conclusion: The results of this study indicate that the BeHaS exercise program can play a useful role in improving depression and life satisfaction in institutionalized elderly people with CVA.

  • Purpose: The purpose of this study was to identify the effects of cancer-overcome BeHaS exercise program on shoulder joint function, stress, body image and self-esteem in women who have had surgery for breast cancer. Method: A non-equivalent control group pre-post test design with an experimental group (n=25) and a control group (n=25) was used. The experimental group participated in the program once a week for eight weeks. Data were analyzed using descriptive statistics and Chi square and t-test with the SPSS Win 17.0. Results: There were significantly increased in shoulder joint function (p=.012), body image (p=.001), and self-esteem (p=.013), and significantly decreased in stress (p=.003). Conclusion: The results suggest that breast cancer-overcome BeHaS exercise program had beneficial effects on shoulder joint function, body image, self-esteem and stress in patients who have had surgery for breast cancer.

The Converge Effects of the BeHaS Exercise Program on Health Status, Depression and Suicidal Ideation in Female Elderly Who Live Alone in Community (베하스 운동프로그램이 지역사회 여성노인의 신체건강, 우울, 자살생각에 미치는 융합적 효과)

  • This study was conducted to evaluate the converge effects of the Be Happy and Strong (BeHaS) exercise program on female elders living alone, using a nonequivalent control-group pretest-posttest design. The BeHaS exercise program was conducted twice each week for 4 weeks (total 8 sessions). The outcome measures included pain, shoulder flexibility, grip strength, depression, and suicidal ideation. Independent t-test, Chi-squre test, paired t-tests and ANCOVA were used for the statistical data analysis. A statistically significant improvement emerged in pain (t=4.044, p=.000) and right and left shoulder flexibility (t=2.192, p=.038 and t=2.568, p=.016) 4 weeks later. In a group comparison, a statistically significant difference arose in changed scores of suicidal ideation (F=7.32, p=.010) between groups. The BeHaS exercise program may effectively improve the physical and psychological health of female elders living alone.

  • Salmonella typhimurium MMP13 and S. typhimurium ${\chi}8554$ were derived from weak JOL401 and strong ${\chi}3339$ virulent strains. Heat-labile subunit B (LT-B) was used as an adjuvant to increase the effectiveness of the vaccine. Plasmid pMMP184 carrying a ghost cassette was transformed into MMP13 and ${\chi}8554$ to produce the ghost, and the prepared ghost cells were administered into the muscles of BALB/c mice. In the absence of the adjuvant, the total IgG content showed a tendency to increase contrary to the original virulent strength. In contrast, in the presence of the adjuvant, the strain that originated from the strong virulent showed a tendency to promote the immune more than that of weak virulent strain. However, the final concentration of total IgG was similar between the compared groups, indicating that the originated virulent strength does not affect a specific immune. Other elements of the immunoglobulins IgG1, IgG2a, and sIgAs did not show a specific trend. The results of Salmonella challenge showed a similar tendency to regardless of the originated virulence. Taken together, the results suggest that the Salmonella ghost cells promoted the immune system of BALB/c mice, irrespective of the virulence applied to create the ghost cells.

  • Novel highly active visible-light photocatalysts in the form of zinc bismuth oxide ($ZnBi_2O_4$) and graphite hybrid composites were prepared by coupling via a co-precipitation method followed by calcination at $450^{\circ}C$. The asprepared $ZnBi_2O_4$-graphite hybrid composites were tested for the degradation of rhodamine B (RhB) solutions under visible-light irradiation. The existence of strong electronic coupling between the two components within the $ZnBi_2O_4$-graphite heterostructure suppressed the photogenerated recombination of electrons and holes to a remarkable extent. The prepared composite exhibited excellent photocatalytic activity, leading to more than 93% of RhB degradation at an initial concentration of $50mg{\cdot}L^{-1}$ with 1.0 g catalyst per liter in 150 min. The excellent visible-light photocatalytic mineralization of $ZnBi_2O_4-1.0graphite$ in comparison with pristine $ZnBi_2O_4$ could be attributed to synergetic effects, charge transfer between $ZnBi_2O_4$ and graphite, and the separation efficiency of the photogenerated electrons and holes. The photo-induced $h^+$ and the superoxide anion were the major active species responsible for the photodegradation process. The results demonstrate the feasibility of $ZnBi_2O_4-1.0graphite$ as a potential heterogeneous photocatalyst for environmental remediation.

  • This experiment was conducted to investigate the effect of nitrogen fertilization in job's tears (Coix lachryma-jobi L.) on the growth characteristics, grain yield, nitrogen accumulation, and chemical property of soil after harvest. Heading and budding stages were shorter than control but growth periods was increased because of the increase of ripening periods according to the increase of nitrogen fertilizer applications. Number of main culm node and culm diameter was similar but culm length and tiller number per plant were better according to the increment of nitrogen fertilizer applications than control but the decrease of grain yield was attributed to the fact that damage by corn borer was 30% in $240kg\;ha^{-1}$ of nitrogen treatment. Some of yield components was better according to the increment of nitrogen fertilizer applications but grain number per plant of $160kg\;ha^{-1}$ of nitrogen treatment was greater. So grain yield was the highest ($3,410kg\;ha^{-1}$) at the $160kg\;ha^{-1}$ of nitrogen fertilization. Nitrogen use efficiency decreased according to the increase of nitrogen fertilization. Total nitrogen of soil after experiment in 0, $80kg\;ha^{-1}$ of nitrogen treatments was lower and in 160, $240kg\;ha^{-1}$ of nitrogen treatments was higher than that before the experiment.
