A smart leveling equipment was developed in this study by improving present leveling equipment. Both hardware and software of the equipment was developed and several accuracy tests of bench mark were conducted using various survey equipments. National control point (UO992-A), control points (15-00-06-24)-B and (15-00-06-23)-C were used for the accuracy test. As a result, the stable results in the range of errors were obtained in the cases of auto-level and digital level. Approximately 24mm error in the section of A-B and 26mm of B-C section was occurred in Smart Level equipment. This is due to the lack of technology completion and errors via relatively many numbers of installation tests. 46mm error of RMSE of smart level survey was occurred through the difference of section test. A small error was detected in short range but errors were accumulated far from the bench mark. It's concluded that an in-depth study emphasizing accuracy improvement can be practically applied to the various areas of industry.

Due to the international economic downturn and the increasing competition, container terminals have been trying to achieve cost effectiveness and high service levels. Shipping companies want to get better services from container terminals but container terminals only have limited space and equipment. Frequently, too many external trucks come to the terminal at the same time, and create bottle necks at the terminals. Ouside the container terminals traffic jams occur as well. As a result, stakeholders need a vehicle booking system. By VBS, container terminals can plan efficiently in advance to avoid work delay and the truck drivers can finish their jobs quickly. This paper aims to search efficient models for the container terminals by using VBS.

The goal of this research is to understand the extent to which active seniors' mobile app usage level affects their lifestyle and life satisfaction. For this, we surveyed for 15 days in early December 2021 targeting about 150 users nationwide. As the questionnaire content, the independent variable was "mobile app usage level", the parameter was "lifestyle", and the dependent variable was "life satisfaction". As a result of empirical analysis, reliability and exploratory factors between each variable were verified, and it was confirmed that internal consistency was secured. It was investigated that the concentration validity of each item was generally well confirmed. As a result of hypothesis testing by the structural equation, 'App usage level ⇨ Lifestyle' was 0.244, 'Lifestyle ⇨ Life satisfaction' 0.707, and 'App usage level ⇨ Life satisfaction 0.141' was adopted. This study shows that the higher the level of mobile app usage of active seniors, the higher the lifestyle. Also, the better the lifestyle, the better the quality of life. It is analyzed that life satisfaction will improve as the level of mobile app use increases. Therefore, in order to improve life satisfaction, it seems necessary to increase the level of app use and lifestyle.

The purpose of this study was to examine the effect of physical fitness improvement program on work intensity of persons with Down syndrome. For this, 8 adults with Down syndrome participated in program and were evaluated. The physical fitness improvement program consisted of grasp, lifting, carrying exercise for 12 weeks, 1 day a week for 2 hours per session. Compared with pre-program conditions, participants in program improved significantly in right grasp power, lifting ability but there was not significant improvement in carrying ability. In view of work intensity, work intensity level of two subjects was changed from average to hard in lifting. One subject was changed from very light to average and two subjects was changed from light to average in carrying. This results suggested that physical fitness improvement program was helpful for promotion the intensity of adults with Down syndrome.

The purpose of this study is to suggest the integrated entrepreneurial competency models that reflect critical entrepreneurial competencies that entrepreneurs should have at different stages, thereby enhancing the success rate of ventures. To accomplish the purpose, this study developed the hypotheses about the positive effects of entrepreneurial competencies on business performance, and the moderating effect of learning competency to strengthen the relationship between entrepreneurial competencies and business performance. The results of this study are as follows. First, the technological functional competency of entrepreneurial teams, the resource utilization and business planning competency of entrepreneurs in the early stage of business development were found to significantly affect both non-financial and technological performance. The opportunity recognition competency has a significantly positive effect on non-financial performance. In addition, it is analyzed that learning competency significantly moderated the relationship between entrepreneurial competencies(technological functional, resource utilization) and non-financial performance. The moderating effect of learning competency between business planning competency and technological performance was also found to be significant. Second, leadership and resource acquisition competency of entrepreneurs in the late stage of ventures have significantly positive effects on both non-financial and technological performance. The strategic competency has a significantly positive effect on non-financial performance. It was also found that the moderating effect of learning competency between strategic competency and non-financial performance was significant. Finally, the results show that both non-financial and technical performance of NTBVs are significant determinants of financial performance.

소프트웨어 테스트는 소프트웨어 개발 과정에 매우 중요한 요소이다. 현재 많은 조직들이 테스트 성숙도를 높이기 위한 노력을 진행하고 있다. 그 중에서 일리노이공대의 TMM(Test Maturity Model)이 대표적이라고 볼 수 있다. 하지만 TMM은 바로 테스트 성숙수준을 측정하는데 문제가 있다. 그래서 TMM과 테스트 프로세스를 향상시킬 수 있는 TPI(Test Process Improvement) 모델을 통해, 우리는 Enhanced-TMM에 테스트 속성과 성숙도 상호관련 매트릭스를 사용한 테스트 성숙수준 측정 방법을 구체적으로 제안하고자 한다.

1983년 부터 3년여에 걸쳐 유한양행 중앙연구소에서 우수 균주 개량및 발효법에 의한 효소생산을 확립시켜 산업화 가능 수준까지 도달하였다. 그러나 당사에서 생산시 국제가격하락및 품질경쟁을 예상할때 실제 생산에서는 실험실 수준의 2배 이상의 역가향상과 회수율 향상이 필요하였고, 실험실에서 손쉽고, 경제적인 생산방법들이 규모가 큰 공장 설비에서는 경제적이지 못했으므로 별도의 산업화 작업이 필요하였다. 이러한 일련의 scale-up 실험은 연구소의 여러 기초 실험결과를 토대로, 기존설비들에 적합하게, 대량생산이 가능하게, 작업이 안전하게, 생산성의 변동이 적게, 공정속도가 빠르게, 경제성이 높게하는 것을 목표로 진행시켰다. 이미 항생제 Rifamycin 발효생산을 통하여 축적된 기술 경험을 최대한 되살려 발효및 회수 정제의 산업적 기술개발에 응용하였다.
