Purpose: OSCE, Objective Structured Clinical Examination, is a good way to evaluate clinical skills of nursing students. To do this, we need modules, evaluators, persons to run the examination, as well as models and standardized patients if necessary. Author coached nursing students to develop modules and ran the examination by themselves. Method: 24 third-year and 4 first-year students volunteered; third-year students developed 5 modules, and organized and ran the examination. First-year students played patient role. 60 2nd-year students participated as examinees. Modules were duplicated to finish examination in a given time. The relationship between OSCE score, conventional clinical evaluation score and credit of students was compared. Effect of module duplication on score was tested. And responses of examinees were collected. Results: There was no correlation between OSCE and conventional clinical evaluation score (r=0.07), and credit (r=0.27), And there was no difference of OSCE score between duplicated modules $(53.77{\pm}7.61$ vs $55.33\pm7.74).$ Response of examinees to OSCE was favorable. Examinee did not expressed resistance for the evaluation by OSCE developed and ran by students. Conclusion: Nursing students successfully developed and ran OSCE, which was accepted favorably by examinees. Student-developed OSCE may play a role in evaluation of clinical performance.

The unit modular construction system is a building technique in which unit modules are manufactured at a factory and then assembled at the construction site. It has many benefits, including reduction of the construction period and improvement in quality. For this reason, it is utilized for various purposes in Japan and England. While it has been introduced in Korea, there have been few Korean studies conducted on the unit modular system. In particular, little research has been done on the method of safely fixating the unit modules to a truck. Therefore, this study reviewed the fixation methods of unit modules for transport, analyzed the problems, and designed a fixation device for unit modules. In addition, a device for the fixation of unit modules to a truck was developed, and a structural simulation was implemented for a safety test by considering the maximum stress generated during the transport of the unit modules fixed on a truck. When the device for the fixation of unit modules is manufactured based on the results of the structural simulation done in this study, it is expected to aid the development of a more practical fixation device for unit modules.

Recently, specifications of flat display module is going to be higher definition, brightness and more wide viewing angle. On the other hand, physical thickness of those modules is forced to be slimmer and lighter. The flat display modules such as plasma or TFT-LCD employ thin crystallized panels that are normally weak to high level transient mechanical energy inputs. As a result, anti-shock performance is one of the most important design specifications of TFT-LCD modules. TFT-LCD module manufacturers and their customers like PC or TV makers perform a series of strict impact/drop test for the modules. However most of the large display module designs are generated based on engineer's own trial-error experiences. Those designs may result in disqualification from the drop/impact test during final product evaluation. A rigorous study on the impact failure of the displays is of course necessitated in order to avoid the problems. In this article, a systematic design evaluation is presented with combinations of FEM modeling and testing to support the optimal shock proof display design procedure.

Seismic performance evaluation of existing building usually needs much time and man power, especially in case of nonlinear analysis. Many data interaction steps for model transfer are needed and engineers should spend much time with simple works like data entry. Those time-consuming steps could be reduced by applying computerized and automated modules. In this study, computational platform for seismic performance evaluation was made with several computerized modules. StrAuto and floor load transfer module offers a path that can transfer most linear model data to nonlinear analysis model so that engineers can avoid a lot of repetitive work for input information for the nonlinear analysis model. And the new nonlinear property generator also helps to get the nonlinear data easily by importing data from structural design program. To evaluate the effect of developed modules on each stages, seismic performance evaluation of example building was carried out and the lead time was used for the quantitative evaluation.

This paper presents an allocation model of test times of software modules. An evaluation measure of modules which is based on the data flow path between modules is used at test phase. An evaluation measure is expressed by the possible path number of data flow for each module, which can be interpreted as an importance of individual module. Three criteria : module test time, module reliability, and system reliability is considered in this model. Multi-objective programming, hence, is used to solve this model.

Photovoltaic (PV) power generation is the world's best and largest renewable energy that generates electricity with infinite sunlight. Solar cell modules are a component of photovoltaic power generation and must have a long-term durability of at least 25 years. The development of processes and equipment that can be recovered through the recycling of metals and valuable metals when the solar module's lifespan is over has been completed to the level of commercialization, but few processes have been developed that require repair due to initial defects. This is mainly due to the economic problems caused by remaking. However, if manufacturing processes such as repairing solar cell modules that have been proven to be early defects are established and the technical review of long-term reliability and durability reaches a certain level, it is considered that it will be a recommended process technology for environmental economics. In this paper, assuming that a defective solar cell module occurs artificially, a manufacturing process for replacement of solar cells was developed, and a technical verification of the manufacturing technology was conducted through long-term durability evaluation in accordance with KS C 8561. Through this, it was determined that remanufacturing technology for solar cell replacement of solar cell modules that occurred in a short period of time after installation was possible, and the research results were announced through a journal to commercialize solar modules using manufacturing technology in the solar market in the future.

최근 온톨로지 모듈을 이용하여 효과적으로 온톨로지를 구축하려는 시도들이 증가하고 있으며 이에 따라 다양한 온톨로지 모듈화 기법들이 제안되어왔다. 이들 기법들은 각각의 모듈화 목표와 기준을 바탕으로 개발되어 왔으나 모듈화 기법들을 평가할 수 있는 공통된 기준 및 평가 프레임워크가 정립되지 않아 서로 비교하기 어려운 실정이다. 또한 온톨로지와 관련된 평가에 대한 연구들이 지금까지 활발히 이루어져 왔지만 주로 온톨로지 단위의 평가가 중심이 되어왔으며 온톨로지 모듈화 기법의 평가에 대한 가시적인 연구들이 부족하다. 그러나 획일적이고 대용량인 온톨로지 사용의 문제점과 모듈화 필요성에 대한 인식과 함께 온톨로지를 모듈화하는 작업에 대한 평가 필요성이 제기되고 있다. 그러므로 본 연구에서는 온톨로지 모듈화 작업 과정과 모듈화 결과물인 모듈 그리고 모듈화 도구에 대한 총괄적인 평가를 제공하는 프레임워크를 제안한다. 또한, 본 연구에서 제시한 평가 프레임워크를 실증적 실험을 통해 SWOOP, PATO, Prompt 등 모듈화 기법에 적용하였다. 본 연구의 결과를 통하여 온톨로지 엔지니어들이 온톨로지 모듈화 작업의 품질을 개선시킬 수 있고 온톨로지 사용자들이 사용 목적에 맞는 온톨로지 모듈화 기법을 선택할 수 있도록 한다.
