This study is a case study that attempt to quantify the economic efficiency of 'digital library program(DLP) of the National Library of Korea' by means of cost-benifit analysis. Results indicate that the B/C ratio is 1.70 which can be interpreted the economic efficiency of DLP is very high. Of particular significance is the fact that this study empirically proves that the digital library program is economically efficient.

Objectives: This study was performed to evaluate the effect of navigator education program for cancer screening, which is designed for improvement in knowledge of cancer, perceived self efficacy and communication skill of the breast and cervical cancer screening for middle-aged and aged women in urban areas. Cancer screening navigator is lay health advisor who are educated for providing information, emotional support about cancer screening at the community. Methods: The subjects were 33 women at the age of 40-69 and educated for 12 hours through the education program. The control group subjects were 30 women. For statistical analysis, descriptive statistics and paired t-test were used with SPSS WIN 14.0. Results: Contents of education program were case of cancer early detection, benefit of breast cancer screening, benefit of cervical cancer screening, health care system for cancer screening, role of cancer screening navigator, communication skill, transtheoretical model and role play. Knowledge of cancer(t=4.267, p=0.000) and communication skill(t=4.947, p=0.000) of the women increased significantly after implementing the 12 hours education program. Conclusion: The results suggest that navigator education for cancer screening has an effect in increasing knowledge of cancer, and communication skill scores.

The purpose of this study is to investigate the seismic behavior of RC bridge piers and to provide the data for developing improved seismic design criteria. The accuracy and objectivity of the assessment process may be enhanced by the use of sophisticated nonlinear finite element analysis program. A computer program, named RCAHEST(reinforced concrete analysis in higher evaluation system technology), for the analysis of reinforced concrete structures was used. Material nonlinearity is taken into account by comprising tensile, compressive and shear models of cracked concrete and a model of reinforcing steel. The smeared crack approach is incorporated. n boundary plane at which each member with different thickness is connected, local discontinuity in deformation due to the abrupt change in their stiffness can be taken into account by introducing interface element. The effect of number of load reversals with the same displacement amplitude has been also taken into account to model the reinforcing steel and concrete. In the companion paper, the proposed numerical method for seismic damage evaluation of RC bridge piers is verified by comparison with the reliable experimental results.

Forage breeding laboratory of National Livestock Research Institute, R.D.A. has made interspecific hybrids of Lolium multiflorum $\times$ L. pratensis and intergeneric hybrids of Lolium $\times$ Festuca since 1984, and has collected ecotypes of Italian ryegrass since 1991. Growth characteristics of these hybrids and ecotypes were researched, and then these clone lines were named. Among these clone lines, the several clones that have polen fertility, high cold-tolerance, and similar heading time were used for making synthetics, Naehan 6, 7, 8, 9, with polycrossing method in 1997. Field experiments were carried out to compare the mophological and agronomical characteristics and forage productivity and quality of the synthetics with those of Italian ryegrass varieties, Barmultra and Hwasan 101. in Suwon and Yonchun from 1999 to 2000. Heading time of the synthetics were 22th to 24th May that belong to late-mature types to be similar to that of Barmultra and Hwasan 101 in Suwon. The synthetics were 101 to 106 c3n in plant length, medium or thick in thickness of stem, dark peen in leaf color, broad and long in flag leaf, strong in lodging resistance, and excellent in regrowth. Winter survivals of the synthetics were no different from that of Barmultra or Hwasan 101 in Suwon, but better than that of Barmultra or Hwasan 101 in Yonchun where was -10 to -12$^{\circ}C$ of minimum average air temperature in January or February. Dry matter(DM) yields of the synthetics were similar to DM 8,238kg per ha of Barmultra in Suwon, but in Yonchun, were more 7 to 13% than DM 7,291kg per ha of Barmultra. Forage qualities, IVDMD, ADF, NDF and TDN of the synthetics were lower than those of Hwasan 101, but higher than those of Barmultra.

Runtime Intrusion Prevention Evaluator (RIPE), published in 2011, is a benchmark suite for evaluating mitigation techniques against 850 attack patterns using only buffer overflow. Since RIPE is built as a single process, defense and attack routines cannot help sharing process states and address space layouts when RIPE is tested. As a result, attack routines can access the memory space for defense routines without restriction. We separate RIPE into two independent processes of defense and attacks so that mitigations based on confidentiality such as address space layout randomization are properly evaluated. In addition, we add an execution mode to test robustness against brute force attacks. Finally, we extend RIPE by adding 38 attack forms to perform format string attacks and virtual table (vtable) hijacking attacks. The revised RIPE contributes to the diversification of attack patterns and precise evaluation of the effectiveness of mitigations.

이 글에서 살펴본 바의 내용에 의하면 철도차량 습식 바닥구조의 차음성능은 기존의 35 mm를 47 mm로 하는 경우 약 4dB 정도의 차음개선 효과를 기대할 수 있으며, 제진층을 추가로 도입하는 경우 1~2dB의 추가적인 차음개선을 기대할 수 있다고 결론된다. 바닥충격음에 대한 차단성능은 경량충격음의 경우 두께 증가 및 제진층 적용에 의하여 각각 3dB 및 7dB의 차음개선이 예상된다. 그러나 중량충격음의 경우에는 차음개선 효과가 거의 없으며 오히려 감소하는 경우도 있으므로 보다 구체적인 검토 연구의 필요성이 있다.산업계에서는 현재의 진동소음저감기술을 좀더 단시간에 차량개발 프로그램에 적용하는데 더욱 큰 노력을 할 필요가 있을 것이다. 따라서 여기에서는 현재 자동차업체에서 수행하는 진동, 소음및 충격시험평가에 대해서만 국한하여 기술하고자한다.urce)을 찾아 직접 그 원인을 차단 및 치유하는 적극적이고 공격적인 방법을 이용하고있다. 본 글에서는 이러한 진동소음 문제를 차량의 개발 단계에서 해결하기 위한 일련의 과정 및 여러가지 개선기법에 대해서 살펴보고 그를 통한 진동소음 문제 해결방법을 제시하고자 한다.

본 연구의 목적은 병원급식소의 세정작업의 효율적 관리를 위하여 위탁 전과 후의 비용효과를 비교하고 자가운영과 위탁운영체제의 세정담당 종업원들의 직무만족도를 비교하여 그 비용효율성을 분석하는데 있다. 본 연구의 결과에 의하면, 세정작업의 위탁관리로 다음과 같은 잇점을 기대할 수 있었다. 첫째, 호봉이 낮고 적은 수의 종업원 이용으로 인건비의 절감을 기대할 수 있었으며, 둘째, 봉급에 관한 항목을 제외한 다른 항목에 관해서는 자가운영과 위탁운영 체제의 세정담당 종업원들의 직무만족도에 유의적 차이가 없는 것으로 나타났으며, 세째, 작업일정이나 인사배치에 있어서의 용이함으로 나타났다. 이 연구 결과를 기초로 병원급식소의 위탁관리 프로그램에 관한 지속적인 평가와 개발에 관한 연구가 이루어져야 할 것이다.

This study is designed to evaluate the effectiveness of TDM as a peak-period trip reduction strategy. This effort uses as a case study, the implementation of Regulation XV (REGXV) in Southern California, the most ambitious and far reaching employer-based ridesharing program implemented to date. This study explores the program effectiveness in terms of three aspects ; employee travel behavior changes after implementating Regulation XV, TDM programs offered by employers subjects to Regulation XV, and causal relationship between employee travel behavior changes and employer-based TDM programs. The study finds that Regualtion XV has a small, but statistically significant positive impact on AVR change. Popular incentives used by employers are less costly and easy to implement rather than to be effective. The increase in AVR is associated with increases of carpools promoted by strong incentives such as monetary subsides. A large number of indirect incentive programs are not effective. The study concludes that employers need to invest heavily on strong incentives, rather than on proposing diverse incentives, to comply with REGXV.
