The use of big data needs to be emphasized in policy formulation by public officials in order to improve the transparency of government policies and increase efficiency and reliability of government policies. 'Hye-Ahn', a government-wide big data platform was built with this goal, and the subscribers of 'Hye-Ahn' has grown significantly from 2,000 at the end of 2016 to 100,000 at August 2018. Additionally, the central and local governments are expanding their big data related budgets. In this study, we derived the costs and benefits of 'Hye-Ahn' and used them to conduct an economic feasibility analysis. As a result, even if only some quantitative benefits are considered without qualitative benefits, the net present value, the benefit/cost, and internal rate of return turned out to be 22,662 million won, 2.3213, and 41.8%, respectively. Since this is larger than the respective comparison criteria of 0 won, 1.0, and 5.0%, it can be seen that 'Hye-Ahn' has had economic feasibility. As noticed earlier, the number of analysis using 'Hye-Ahn' is increasing, so it is expected that the benefits will increase as time passes. Finally, the socioeconomic value gained when the results of analysis using 'Hye-Ahn' are used in policy is expected to be significant.

Purpose: This study was conducted in order to determine the effects of a health promotion program on perception of health behavior, physical fitness, and body composition in child care helpers. Methods: The study had a one group pretest-posttest quasi-experimental design. Data were collected from 38 child care helpers from July 6 to November 9, 2013. The health promotion program consisted of health education, self-exercise, encouragement, and identification. The following data were collected perception(perceived benefit, barrier, and self-efficacy), physical fitness(balance, grasp power, and flexibility), and body composition(body mass index, body fat ratio, waist circumference, and basal metabolic rate) and analysis was performed using on SPSS WIN 18.0. Results: Self-efficacy showed a significant increased. Body mass index, body fat ratio, and waist circumference showed a significant decreased. No significant difference in perceived benefit, barrier, physical fitness, and basal metabolic rate was observed between pre-test and post-test. Conclusion: This health promotion program had an effect on self-efficacy and body composition in child care helpers. Therefore, this health promotion program for child care helpers can be recommended as an effective nursing intervention.

We are faced with the crisis of the R&D investment because of the effects of the IMF conditions. Most of the laboratories are going to restructure by the cutting off of money, man power and the reduction of R&D thema. Therefore it is necessary to allocate the R&D resources effectively to the R&D projects. The evaluation and the selection of the R&D projects have been recognized as the most important process for the allocation of the R&D resources. The result of the KITA(1997) shows that the commercial success rate of the R&D from new-product brain storming is only 5.8%. This study aims to analyze the actual conditions of the cost benefit analysis(CBA) of R&D projects of selected laboratories and to study measure methods of the R&D benefits. The research method of this study reviews the CBA of R&D firstly, and surveys 200 selected high ranking labs of the R&D expenditures. For the comparison of the results between '87 and '97, this survey used the same questionaries for each year. As the result of the survey only 27 labs(response rate 13.5%) responded. The result of the '97 survey is as follows : The CBA is used by 44% of responding labs. The economic evaluation method for the R&D project selection is used by 48% of labs and this numbers increased by over 10 percents points compared with the result of '87. The CBA is used for about 40% about each of the budget preparing and the budget analysis, and by 30% of labs to analyze sales and expenditures of the overall period of the project. As the measurement of benefits of R&D projects, 30% of labs responded that it is impossible to measure the benefits, and 20% of labs measured the benefits between sales and expenditures of the R&D project.

Background: There is no suggested molecular indicator for the determination of which patients will benefit from anti-angiogenetic treatment in metastatic colorectal cancers. Materials and Methods: In this study, VEGF and $HIF-1{\alpha}$ expression and their clinical significance were studied in tumor tissues of patients with colorectal cancer receiving bevacizumab-based treatment. VEGF and $HIF-1{\alpha}$ were assessed by immunohistochemistry in the primary tumors of 53 metastatic colorectal cancer patients receiving chemotherapy in combination with first line bevacizumab. Results: The clinical benefit rate in the low-VEGF expression group was 38%, while it was 62% in the high expression group. While the median progression-free survival (PFS) was 10 months in the high-VEGF expression group, it was 8 months in the low-VEGF expression group (p = 0.009). The median overall survival (OS) was found to be 26 months vs 15 months. Thus, when VEGF was strongly expressed it was in favor of that group and the difference was statistically significant (p = 0.03). High VEGF expression rate was an independent factor that correlated with OS or PFS (p=0.016 and 0.009, respectively). Conclusions: The data showed that VEGF may have predictive value for determining the treatment of CRC.

Background : Previous studies have suggested a lack of complete cross-resistance between steroidal (exemestane) and non-steroidal aromatase inhibitors (nSAI). Methods : Eighty-eight metastatic breast cancer (MBC) patients who received 25 mg of exemestane orally once a day at the National Cancer Center, Korea, between 2003 and 2009, were reviewed retrospectively. All patients had received nSAI for metastatic disease prior to exemestane therapy. Results : The median age was 52 years (range, 33-79), and 13 (14.8%) patients were premenopausal who concomitantly received GnRH agonist. Exemestane was given as a second- (80.7%) or third-line (19.3%) hormone therapy. The clinical benefit (CB) rate (complete response + partial response + stable disease ${\geq}$ 24 weeks) was 30.7%, with a median CB duration of 10.0 months (range, 6.3-78.7). The median progression-free survival (PFS) was 3.0 months (95% confidence interval [CI], 1.99-4.01) and the overall survival (OS) 21.5 months (95% CI, 17.96-25.04), with a median followup of 50.3 months. Patients who achieved CB had longer OS than those patients who did not (29.6 vs 17.9 months; P=0.002). On univariate analysis of predictive factors, patients who had achieved CB from previous nSAI tended to show lower CB rate (24.6% vs 44.4%, respectively; P=0.063) and shorter PFS (2.8 vs 4.8 months, respectively; p=0.233) than patients who had not. Achieving CB from previous nSAI became independent predictive factor for CBR to exemestane on multivariable analysis (Odds ratio = 2.852, P = 0.040). Conclusions : Exemestane after nSAI failure was effective in prolonging CB duration. The drug's efficacy seemed to be inferior in patients who had benefit from previous nSAI use.

The relative importance of leisure trip has been increased after adopting the five-day workweek system and considering the higher income level. Thus, the value of travel time for intercity leisure trips should be estimated to conduct a reasonable benefit/cost analysis for railway construction projects. In this paper, the value of travel time was estimated separately for each trip purpose such as business, leisure, and other non-business than leisure. The estimated values of leisure travel time ranged from 5,310 to 14,185 (won/hr) by altering travel mode, and were increased by 42-107% when comparing with those of non-business travel time. Besides, how to apply the value of intercity leisure travel time for B/C analysis of railway projects was suggested. For the construction case of a railway connecting Chuncheon and Sokcho, the estimated benefit was increased by 2.3%.

Glasshouse investigations were carried out to investigate the development and yield of Atylosia scarabeoides on soils of the northern guinea savanah zone of Nigeria. Seeds were sown at four rates 50, 75, 100 and 125 kg/ha. Single superphosphate (SSP) fertilizer was applied at sowing at four rates 0, 60, 90 and 120 kg/ha. Seeding (plant) population at one month and at harvest was significantly (p < 0.01) influenced by seeding rate but not fertilizer level. Fresh herbage yield was strongly (p < 0.01) dependent on fertilizer level, with the highest (not significant) dry matter yield at 90 kg SSP/ha. Seeding rate had no significant effects on herbage yield. The crude protein content of herbage rose with increase in fertilizer level although there were no significant differences between the various seeding and phosphorus rates. No significant interactions were observed between seeding rate and phosphorus lever. The yields were generally high, indicating good prospects for pasture development with A. scarabeoides in the zone, although field trials would be of benefit.

This research is aiming to specify the requirement of the investment such as initial cost, running cost earning rate to make effective investment considering the purpose of remodeling and economical value of store building enough to meet the initial purpose of remodeling. The review of earning rate for economical evaluation was performed by the on-site auditing on the structure and function of the building and applying the assessment simulation program, which is to find the possible business model to identify the requirement of building owner through case study. After the research, the following results are obtained. First, it is important that many aspects should be carefully analysis and the best method should be selected as characteristics of remodeling can be defer each other in their implementations. Second, though the remodeling of exist buildings to promote the functions has been applied. no suitable assessment tool has bee developed for deciding the level of remodeling in the view of economical efficiency so far. Third, the economical benefit was evaluated by analysing annual earning rate which is applied by investment items and recovery period for the investment. More specific data bate should be established to apply the suggested economic accession in business enough to forecast the future circumstances. More researches should be promoted on this area continuously as well as the integrated economic evaluation of remodeling on existing building.
