Purpose: The purpose of this study was to prove the effects of coordinative locomotion training (CLT) on walking speed, walking endurance, and balance for incomplete spinal cord injury patients. Methods: Ten subjects were randomly assigned to the CLT group (n = 5) and the treadmill (TM) group (n = 5). The CLT group performed PNF pattern exercise using the motions of the sprinter and skater for 30 minutes, while the TM group performed using a treadmill for 30 minutes. Both groups performed these therapeutic interventions for five days per week, for a period of four weeks. A 10 meter walking test, Berg Balance Scale (BBS), and 6 meter walking test were used for the assessment of gait speed, balance, and gait endurance. The SPSS Ver. 18.0 statistical program was used for data processing. A Wilcoxon signed rank test was used for the comparison of pre- and post-intervention performance and a Mann-Whitney test was used for comparison between the groups. The significance level for the statistical inspection was set at 0.05. Results: Both groups showed significant improvements in the 10 meter walking test, Berg Balance Scale, and 6 meter walking test (P < 0.05). Conclusion: CLT had an effect on the improvement of walking speed, walking endurance, and the balance of incomplete spinal cord injury patients. Thus, we suggest that CLT is a therapeutic intervention for incomplete spinal cord injury patients.

Analog instrument and control systems in nuclear power plants have recently been replaced with digital systems for safer and more efficient operation. Digital instrument and control systems have adopted various fault-tolerant techniques that help the system correctly and safely perform the specific required functions regardless of the presence of faults. Each fault-tolerant technique has a different inspection period, from real-time monitoring to monthly testing. The range covered by each faulttolerant technique is also different. The digital instrument and control system, therefore, adopts multiple barriers consisting of various fault-tolerant techniques to increase the total fault detection coverage. Even though these fault-tolerant techniques are adopted to ensure and improve the safety of a system, their effects on the system safety have not yet been properly considered in most probabilistic safety analysis models. Therefore, it is necessary to develop an evaluation method that can describe these features of digital instrument and control systems. Several issues must be considered in the fault coverage estimation of a digital instrument and control system, and two of these are addressed in this work. The first is to quantify the fault coverage of each fault-tolerant technique implemented in the system, and the second is to exclude the duplicated effect of fault-tolerant techniques implemented simultaneously at each level of the system's hierarchy, as a fault occurring in a system might be detected by one or more fault-tolerant techniques. For this work, a fault injection experiment was used to obtain the exact relations between faults and multiple barriers of faulttolerant techniques. This experiment was applied to a bistable processor of a reactor protection system.

This study aims to explore a plan for the educational application of K-MOOC brought into relief as a new education system and to draw a direction of improvement for increasing learners' satisfaction through the development and operation of the K-MOOC Course. The colleges produce and provide the MOOC Course as a counterplan through college innovation to respond to social changes due to the reduction of school-age population. Thus, this study selected the target courses for the operation of K-MOOC and proceeded with the development of a course, referring to the guidelines for the development and operation of the K-MOOC Course at the National Institute for Lifelong Education with the quantity for 14 weeks (About 50 minutes per week) for the period of the development of the course of about 5 months. The development of the course was made in the stages of design, development, inspection, and operation. The implications of the operation of K-MOOC obtained through this study are as follows: First, in order to increase the utilization of the MOOC Course, it is necessary to operate it in connection with the regular curriculum; second, it is necessary to have desirable communication to induce the interaction and academic motivation between the instructor and the learners; and third, it is necessary to analyze the relationship of the impact by each background factor through analyzing satisfaction with the lecture and continue to assure the quality of the course through understanding the learners' demands. For this purpose, it is important to experience new attempts directly and analyze the performance of education and the satisfaction of consumers and the instructor in detail, and it is necessary to construct a curriculum suitable for K-MOOC and seek an effective teaching method.

The integrity of the SG(Steam Generator) tubes has been challenged by numerous factors such as flaws, operation, atmosphere, inherently degraded materials, loose parts and even human errors. Of the factors, loose parts(or foreign materials) on the secondary side of the tubes can bring about volumetric defects and even leakage from the primary to the secondary side in a short period of time. More serious concerns about the loose parts are their unknown influx path and rapid growth rate of the defects affected by the loose parts. Therefore it is imperative to detect and characterize the foreign materials and the defects. As a part of the measures for loose part detection, TTS(Top of Tubesheet) MRPC(Motorized Rotating Pancake Coils) ECT has been carried out especially to the restricted high probability area of the loose part. However, in the presence of loose parts in the other areas, wide range loose part detection techniques are required. In this study, loose part standard tube was presented as a way to accurately detect and characterize loose part signals. And the SG tube ECT bobbin coil and MRPC ISI(In-service Inspection) data of domestic OPR-1000 and Westinghouse Model F(W_F) were reviewed and consequently, comprehensive loose part detection technique is derived especially by applying bobbin coil signals

Colonialism heretofore described merely as a political economic phenomenon denotes another aspect, namely, an ecological imperialism that accompanies the biological implantation of human beings, crops, weeds, domestic animals, and pathogens onto colonized lands. Foremost, the Korean Peninsula during the colonial period served as a testing ground for the transplanted Japanese varieties of rice. Near the mid-1940s, the new varieties came to dominate over 90% of cultivated rice paddy. The speedy diffusion of transplanted rice was attributable to the aggressive promotion of agricultural institutions led by the Institute of Agricultural Tests and Experiments. Various policies and tactics were also instrumental to the nationwide distribution of new varieties, and they included naming recommended varieties, sponsoring rice contests, establishing crop inspection offices, educating young farmers at training camps, and publishing newsletters for agricultural societies. The forward and backward linkages that came along with the new varieties of transplanted rice helped to consolidate colonial status quo and to create hybrid agricultural landscapes in the Korean countryside.

Objectives: This study is based on Public Care Service for Chronic Diseases in Incheon Metropolitan City featuring Health-Point Service. It is objective to evaluate whether the service could improve self-management ability of hypertension and diabetes patients. Methods: The knowledge about diabetes and hypertension, which can be improved by educational intervention, is considered as one of the most important factor for self-management ability. While the education service have been conducted, 194 patients who have been diagnosed as hypertension and diabetes within 3 months were included. They completed questionnaires two times within 4 months period, which give information about the knowledge, service registration and education experiences. For further inspection, 396 patients who had been diagnosed formerly were studied by cross-sectional analysis. Results: Regardless of service registration or educational intervention, there wasn't statistically meaningful difference between the initial and the follow-up assessments on the knowledge. However, when investigating formerly diagnosed patients, educated patients had better knowledge on hypertension compared with non-educated patients and registered patients, educated patients had the better knowledge on diabetes compared with non-registered patients, non-educated patients. Additionally, analyzing each questions, educated patients got higher grades in questions about definition of hypertension, diabetes managements which they can practice in daily lives. Conclusions: It is probable that long-term service registration and education experiences could improve the knowledge and self-management ability.

There has been a lot of debate between scholars around the folding screen painting, A Beauty under the Tree[조모입여병풍], a collection of Shosoin, Japan. Even though it is preserved in Japan, its distinguished Chinese feature made many scholars to think it might be made in China and be transmitted to Japan. However, the inspection of the material during $1973{\sim}1975$ has revealed an important fact, that is, the feather used in this screen painting belonged to Japanese bird feather. Moreover, a great amount of documents written in Tenbyo(천평승보, 8th century) period, which was thought to be used as the ground material of this painting. Therefore we can get many evidences saying that this painting was made in japan. In a basic sense, I stand on this side just because it has more evidences. However, we must be careful to make a final conclusion. Especially on the precious things like this painting screen, we must take whole considerations as possible as we can. First of all, we must consider whether Japan could have ability to make this. Second, there could be other possibility that Japanese repair the original one with their feathers or papers. In order to prove this, study on other pieces including painting screens should be done. I just suggest an objective international discussion. Lastly, I can find the common feature between the pieces of Shosoin and the ones of United Shilla, which could be influenced by same impact, the Silk road trade in a broad sense.

Although the National Archives of Korea has been receiving transfer of standard electronic documents with a retention period of more than 30 years from the central administration since 2015, errors and inefficiencies persist. Despite this, however, there remain no studies that analyze or address these issues. This study aims to bridge this gap and found that most errors in the transfer process occur at the production stage. To address such, this study proposes a four-step solution. First, before electronic document approval, the text and attached files are checked for defects to prevent errors. Second, as soon as the signature is made, digital signatures are applied on a file-by-file basis to ensure integrity. Third, integrity verification and transfer inspection are automatically performed through digital signature investigation and defect check procedure during transfer and preservation. Fourth and last, the criteria of acquiring records and integrity guarantee technologies are properly applied in production stage with proper management and supervision.

This paper investigates the effectiveness of quick lime piles for soft ground improvement. The field tests based on the results of the laboratory test were performed, and the results of field tests were compared with those of numerical analyses(FEM). The results of the field test showed that the domestic quick lime was very effective in reducing the water contents of the surrounding ground quickly due to its characteristics such as digestion, absorption, and exothermic reactions. Accordingly, consolidation occurred without any additional load increment and the shear strength of surrounding ground was increased more than twice. Therefore the quick lime pile method could be considered as an excellent improvement technique reducing the improvement period for soft ground. For the practical applications of the quick lime pile method, issues such as hydration heat, particulation and equipment enhancement should be solved through continuous research and development.
