As the workers are getting old, they need to be expert in their fields. Expertise is an invaluable means of shipbuilding industries because of the technological advancements. Therefore, the workers have to attend training seminars and upgrade their technical knowledge. In shipbuilding industries, most workers operate transporters based on experience not on learning from specialization in the shipyard. It is needed for the workers of transporters to be educated technical manual and system. Thus, this research shows that educational system which is interactive and very effective with Augmented Reality(AR) for the non-specialist workers. The educational interactive system based on AR is very supportive and worth for the workers. This study considers the system which makes the workers reduce malfunction of the products and mistakes.

The Chuna(推拿) in Korea has been developed since 1990's. Korean Chuna which is the only one manual therapy done by medical doctor is riched by absorbing other nation's manual therapy like Chinese Tuina(中國推拿) and Chiropractic therapy of U.S.A. So, We find that Korean Chuna's peculiarity and development by comparing Chinese Tuina, Chiropractic of U.S.A and Japanese manual therapy which influenced establishment of Korean Chuna. We compared each manual therapy's history, development, diagnosis, correction and treatment of human body, frequently contacting disease and medical service of the present state. Korean Chuna has absorbed other nation's manual therapy and advantage of preserving muscle-skeleton and spinal disorder disease. But, for more prosperity, it needs union of various conception and diagnosis and more research and application to more various disease, for example in internal medicine, gynecology or pediatry and founding system as regular academic work inside the college the possibility which objection and it will practice more completeness. And as one of specialty apprentice doctor subject inside the hospital, the possibility of raising a quality improvement of study and research environment.

Urine sediments are performed by a microscopic examination of centrifuged urine by medical technologists. This study examined different urine sediment preparation procedures. The 107 fresh urine specimens that tested positive from white blood cells (WBCs) and red blood cells (RBCs) in the urine dipstick test and the cobas u 701 analyzer, respectively, were selected for manual microscopy. This study evaluated an automated urine sediment analyzer and three manual microscopy methods for WBCs and RBCs. The methods were performed according to the test guidelines. The coefficients of determination between the cobas u 701 analyzer and the Korean Association of Quality Assurance for Clinical Laboratory (KAQACL) for WBCs and RBCs were r2=0.977 and r2=0.970, respectively. The concordance rates between the cobas u 701 analyzer and KAQACL for WBCs and RBCs were 74.8% and 77.6%, respectively. A good correlation and concordance with the automatic analyzer were shown when the specimens were prepared and examined using the KAQACL method. Consequently, the differences in the urine sediment preparation procedures affected the sediment concentrations, influencing the cell number per high power field (HPF).

Objectives: To evaluate the evidence supporting the effectiveness and safety of Chinese medicine, including Chuna manual therapy, for the treatment ofosteoarthritis. Methods: We conducted a search of 8 electronic databases(Pubmed, Web of Science, EMBASE, Cochrane Library, CAJ, KISTI, NDSL, and RISS) to find all randomized controlled clinical trials that discuss Chuna manual therapy forosteoarthritis till May 2018. Results: Our inclusion criteria selected 7eligible RCTs involving 633 participants. The meta-analysis of 6 studies showed positive results for the useof Chinese medicine, including Chuna manual therapy, for treating knee osteoarthritis. There was no evidence of worsening symptoms or any adverse events. Conclusions: Our systematic review found favorable evidence regardingthe effectiveness of Chinese medicine, including Chuna manual therapy, for treating knee osteoarthritis. However, our systematic review had several limitations owingto the low quality of original articles andadditionalclinical trials would be necessary for stronger evidence.

The leading cause of bridge failures is scouring bed material from around bridge foundations. Many advanced countries such as U.S.A., U.K., the Netherlands and New Zealand have developed and revised their own bridge scour manuals fit for their field conditions. In Korea, researches for reducing bridge failures during floods have concentrated on analysis, laboratory test and countermeasure of bridge scour during the last ten years. however no comprehensive manual for evaluating bridge scour and for identifying the conditions of bridge foundations has been provided yet. In this study, a new bridge scour manual is developed for the accurate evaluation of bridge scour, which reflects domestic field conditions with various streambed materials. The SRICOS method and the Erodibility Index Method are suggested for fine-grained soils and weathered rocks, respectively. In addition, bridge scour analysis algorithms are developed for field engineers to estimate bridge scour depth and to evaluate the susceptibility of bridge scour with ease.

This study aimed to compare the effectiveness of chewable toothbrush and manual toothbrush and provide basic data for recommendation of the chewable toothbrush in specific groups and situations. A total of 20 subjects participated in this study (rolling method, 10; non-rolling method, 10). After professional prophylaxis, participants used the manual toothbrush to brush their teeth for 3 minutes. After a 7-day wash-out period, participants used the chewable toothbrush according to the manufacturer's instructions. Pre- and post-plaque indexing of the teeth was performed. The dental plaque index was assessed using the Turesky Modification of the Quigley-Hein Plaque Index (TMQHPI) for amount of plaque and Silness-Loe Plaque Index (SLPI) for plaque thickness. The difference between pre- and post-dental plaque index was analyzed using a paired t-test and the Wilcoxon signed-rank test. The Mann-Whitney U test was also used to compare the dental plaque index reduction rates. The dental plaque index differed significantly between the chewable toothbrush and the manual toothbrush. The TMQHPI reduction rate was significantly different between the rolling and non-rolling method groups for the manual toothbrush but not the chewable toothbrush. The difference in SLPI reduction rate between the rolling and non-rolling method groups was significant for the manual toothbrush but not for the chewable toothbrush. Differences in the dental plaque index reduction rates between the chewable and manual toothbrushes were not significant in the non-rolling method group. The results of this study showed higher reduction rates in dental plaque with manual toothbrush use than with chewable toothbrush use. However, the non-rolling method group did not show statistically significant differences according to toothbrush type. The present study showed that a chewable toothbrush can be an alternative to a manual toothbrush for individuals who have difficulty using the generally recommended rolling method.

This study aims to look at the process of ginseng being removed from the Western pharmacopoeia in the 19th century, experiencing a crisis as an export product in the America in the 20th century, and eventually settling in the U.S. society and the military as a dietary supplement in the 21th century. In this process, the legislation of provided a bridgehead for ginseng and other botanical dietary supplements to enter the U.S. market. As a result, ginseng could be re-listed in the U.S. pharmacopoeia as a dietary supplement. However, this did not mean a complete soft landing of ginseng and other botanical dietary supplements in the America. The U.S. medical community, which has been afraid of the indiscriminate spread of botanical dietary supplements, has constantly raised "the risk-discourse" and expressed concerns over the use and abuse of botanical dietary supplements that have not been scientifically verified. This involved not only the fundamental problems caused by the lax verification process of , but also a new atmosphere in the U.S. where the public sought information about botanical dietary supplements rather than seeking professional clinicians related to their health. Against this situation, "the advocate-discourse" suggested by dietary supplement manufacturers and the people in charge of botanical products seemed rather relaxed. As consumers are taking this side, the advocates had only to stress that botanical dietary supplements have been used worldwide for a long time without any problems and were made from 'natural' materials. The fact that ginseng and other botanical dietary supplements were able to advance to the U.S. Military's dietary supplement manual, which is strict in controlling food, seems to have jumped on the bandwagon of this atmosphere in the U.S. Society. In the early U.S. dietary supplement manual reviewed in this paper, ginseng was the most detailed among many botanical dietary supplements. Although there are some 'safety concerns' that still exist in the civilian society, but there are also certainly good scientific explanations for the efficacy and references to the popularity and influence of ginseng in the American society. Given this, the U.S. society and military's interest in ginseng as a dietary supplement seem quite high.

In the case of Korea, research on traffic management is insufficient to cover the increasing incidence of disaster. Furthermore, many of the traffic management manual does not touch up on how to administer/manage in case of disaster, except for the one made by 'Korea Expressway Corporation.' In response to this issue, this research is based on a thesis to establish concept of guideline for traffic management in the case of an disaster. In order to achieve this goal, there has been an analysis of the American's manual, molded and changed to be Korea-specific. In the future, based on the u-T circumstances are established, traffic management will become much more efficient. This paper presents important details and ways of management for each step of an disaster event: prevention, preparation, response and restoration.

In this paper, we propose a method to segment a plant from a plant image using U-Net. The network is an end-to-end fully convolutional network that is mainly used for image segmentation. When training the network, we used a binary image that is acquired by the manual segmentation of a plant from the background. Experimental results show that the U-Net based segmentation network can extract a plant from a digital image accurately.
