  • Purpose: This study was done to develop a nursing competency scale according to a clinical ladder system for intensive care nurses. Methods: Index of content validation was done by 20 clinical experts and 80 nurses in Intensive Care Units (ICU). Results: The process and results of study are as follows. First, 12 nursing competencies were used in the establishment of the clinical ladder system (Jang, 2000). Second, the first draft of the competency lists was developed. It was based on the clinical nurses' behavioral indicators of nursing competency by Jang (2000), and was modified and supplemented through various literature reviews including competency standards for specialist intensive care nurses in Australia and consultation with 2 clinical nurses with over 10 years experience in the ICU. Third, the draft was examined by 20 clinical experts for content validity. Finally, the final draft was analysed using clinical validity where 20 nurses in each ladder participated. The final number of items was fixed at 309. Conclusion: The tool represents expected nursing competency of nurses working in ICU. Intensive care nurses can recognize their strengths and weaknesses, and identify directions for their professional growth by analysing results of their competency evaluation using this tool.

  • Purpose: This study was to develop nursing competencies, sub-competencies and behavior indicators according to the clinical ladder of emergency nurses. Method: index of content validation was used by 21 clinical experts. Results: This study had three phases to develop nursing competencies, sub-competencies and behavior indicators. In first phase: 12 nursing competencies and 33 sub-competencies were developed through the literature review on nursing competency and emergency nurses' job description. The content of 12 competencies and 33 sub-competencies were reviewed by 3 nursing professors. The 12 competencies and 33 sub-competencies were followed: clinical judgement and measures(6 sub-competencies), processing ability of ward works(2 sub-competencies), flexibility(2 sub-competencies), resources management(2 sub-competencies), confidence(3 sub-competencies), cooperation(2 sub-competencies), professional development power(2 sub-competencies), patient service orientation(3 sub-competencies), inclination toward ethical value(5 sub-competencies), influence power(2 sub-competencies), developing others(2 sub-competencies), self control(2 sub-competencies). In second phase, 132 behavior indicators were developed according to nurse clinical ladder: novice, advanced novice, competent, proficient. In Third phase, content validity was examined on 132 behavior indicators by 21 clinical experts. 126 among 132 indicators had over 70% agreement among experts and 6 indicators under 70% were revised. Conclusion: nursing competencies, sub competencies and behavior indicators can be used nurses' clinical performance as well as establishing proper directions for professional growth related to reward system.

  • Purpose: The purpose of this study was to investigate how nurses perceive the Career Ladder System(CLS). Methods: This study was a descriptive survey using questionnaires. Questionnaires were developed by an expert group. Participants included 161 nurses working in the Children's Hospital. The data were analyzed using factor analysis, Cronbach's alpha, descriptive statistics, $x^2$-test and ANCOVA. Results: This study revealed that nurses who advanced in their career ladders have a significantly higher perception of participation in their professional activities and a general comprehension of the CLS more than the nurses who did not advance in their career ladders. However, nurses who advanced in their career ladders have a significantly lower perception of the expected outcome of the CLS more than nurses who did not. Conclusions: This result showed that nurses who had experienced in clinical advancement and recognition were highly motivated with their professional activities via the CLS as well as they considered it to allow professional growth.

  • Recently, the government has provided support such as entering new markets, expanding sales channels, and supporting manpower, not just in the form of funding, to efficiently and effectively support limited national resources to improve corporate performance. In this study, we tried to find out the effect of government support for companies that have benefited from the Excellent Technology Research Center Project (ATC Project) and the World Class 300 project using propensity score matching. As a result of the analysis, the effect of government support for the ATC project became visible after the appointment period, while the effect of the World Class 300 project was insignificant. This means that when the size of the company is small, the effect of government support is more pronounced. This suggests that in order to maximize the effectiveness of government support, appropriate national policy interventions such as government innovation funding are needed when the size of the company is small. In this study, differences in the timing, performance indicators, and company size of policy support effects were found in the growth stage of a company from a mid- to long-term time series perspective, suggesting that support policies based on this need to be adjusted and redesigned.

  • This study aimed to investigate the effect of ladder-climbing exercise training on neurobiological markers in the hippocampus of mice with type 2 diabetes (T2DM). Twenty-one C57BL/6 male mice were randomly assigned to the non-diabetic control (NDC, n = 7), diabetic control (DC, n = 7), and diabetic training (DT, n = 7) groups. The DT group performed ladder-climbing training (LCT) five times a week for eight weeks. We measured the levels of hippocampal neurobiological markers (catalase [CAT], brain-derived neurotrophic factor [BDNF], nerve growth factor [NGF], amyloid-beta [Aβ], tau, and CC motif chemokine ligand 11 [CCL11]). The BDNF levels were significantly higher in the DT group than in the DC group (p < 0.05). The Aβ and CCL11 levels were significantly higher in the DC group than in the NDC and DT groups (p < 0.05). The tau levels were significantly higher in the DC group than in the NDC group (p < 0.05). However, there was no significant difference in CAT and NGF levels among the groups (p > 0.05). These results suggest that while T2DM could induce neurodegeneration, LCT may be effective in alleviating neurodegeneration caused by T2DM.

  • Purpose : This study aimed to verify the effectiveness of the clinical ladder system (CLS) by identifying the perception of the CLS, professional self-concept, self-efficacy, and organizational commitment among intensive care unit (ICU) nurses. Methods : Data were collected through a questionnaire survey of 173 nurses working in 11 ICUs at a tertiary hospital in Seoul. Results : The perception of the CLS, self-efficacy, and organizational commitment showed significant difference according to the CLS level. As a result of the partial Spearman correlation analysis after adjusting for demographic difference according to CLS (age, marital status, education, and clinical career), CLS positively correlated with the perception of the CLS (r=.16, p=.045), professional self-concept (r=.24, p=.001), and self-efficacy (r=.21, p=.007). On the contrary, organizational commitment negatively correlated with the perception of the CLS (r=-.43, p<.001) and self-efficacy (r=-.32, p<.001). Conclusion : The CLS is effective for professional self-concept and self-efficacy. However, specialists 2 nurses, who had high professional self-concept and self-efficacy, showed low level of organizational commitment. Thus, it is necessary to examine the factors of work burden and career plateau that are imposed after promotion and improve experience and planning according to the growth needs. Moreover, regular evaluation of the CLS will require hospital support to ensure that ICU nurses appreciate and actively participate in the support.

  • Purpose: The purpose of this study was to identify and describe nurses' experience of a career ladder program (CLP) in a general hospital in Korea. Methods: The data were collected from 15 nurses who participated in the CLP. Each nurse completed individual in-depth interviews, for which the main interview question was "How do you describe your experience of CLP?" All interview data were transcribed and were analyzed using the grounded theory method. Results: The core category of the experience of CLP was identified as "challenging to rebirth as an expert". The participants used five action/interaction strategies such as "taking some time for introspection", "appreciating the essence of nursing", "making use of feedback positively", "throwing away doubts about their own capabilities", "exerting themselves with confidence". The consequence of the process of adjusting to CLP was "positioning a differentiated expert". Conclusion: The results of this study show that participants recognized CLP as a powerful resource which leads them to professional growth and development. Thus, CLP could be utilized as a clinical career-promoting program and ultimately as a program for providing high-quality nursing services.

  • Purpose : Trichosanthis Radix is traditional medical herb which has been shown to inhibit tumor cell proliferation. In this study, the effects of Trichosanthis Radix extract were investigated on inducing growth inhibition and apoptosis of human uterine cervical carcinoma cells. Methods : Human uterine cervical carcinoma cells line, ME-180, was used for the study. The cells were treated with varying concentrations of Trichosanthis Radix extract. Cell growth and inhibitory rate were measured by MTT assay. Apoptosis induction was detected by fluorescence microscopy, DNA ladder formation and flow cytometry. Results : Trichosanthis Radix extract inhibited the growth of human uterine cervical carcinoma cells in a dose-dependent manner. It induced ME-180 cells to undergo apoptosis including fragmented nuclei and nucleosome-sized DNA fragmentation. Flow cytometric analysis showed the increasing rate of apoptotic cells by Trichosanthis Radix extract. Reduction of mitochondrial membrane potential and increase in caspase-3 activity and were found in ME-180 cells treated with Trichosanthis Radix extract. Conclusion : Our data suggest that Trichosanthis Radix extract inhibit the growth and proliferation of ME-180 cells by apoptotic induction and facilitates its activity via caspase-3 activation initiated by depolarization of mitochondria.

  • In a continuous effort to develop novel anticancer agents we newly synthesized and evaluated the antitumor activity of nucleoside analogues. One analogue, 4 - [2-Chlor-6- (3-iodo- benzy lamino) -purin -9-yl]- 2,3-dihydroxy-cyclopentanecarbo xylic acid methylamide (LJ-331), has been shown to exert a potent inhibition of human cancer cell growth in vitro including human lung (A549), stomach (SNU-638) and leukemia (HL-60) cancer cells. Following mechanism of action study revealed that LJ - 331induces cell cycle arrest at the G1 phase in HL-60 cells and evokes apoptotic phenomena such as an increase in DNA ladder intensity and chromatin condensation by a dose- and time-dependent manner. LJ-331 also activated the caspase-3 activity in HL-60. This result suggests that the growth inhibition of human cancer cells by LJ-331 might be related to the cell cycle arrest and induction of apoptosis.

  • The urushiol-ethanol corpuscle of 320 nM in average particle size was prepared and concentrated by ultra homogenization and centrifugation. The cytotoxic profiles of this particle for use as anti-tumor agent have been evaluated in vitro in cultures of human fibroblasts (MRC-9) and celvical carcinoma cells (CUMC-3). The cytotoxicty assays revealed that the inhibitor effect of $10^{-5}$ M urushiol-ethanol particle on the growth of MRC-9 was hardly detected, while CUMC-3 cells exhibited over 50% of growth inhibition under the same conditions. In addition, a clear multiple-unit ladder pater of apoptotic DNA was observed for the urushiol treated CUMC-3 cells. Thus, the results indicated that urushiol inhibited growth of celvical carcinoma cells by inducing apoptosis, which is a mechanism observed with other typical antitumor agents.
