In this study, the number of non-English speaking visitors is increasing day by day, and accordingly, there was a limitation in language communication and communication during radiographic examination. To this end, after distributing the handbook produced for inspection, the improvement effect of before and after explanation was examined. The score scale was not statistically significant as to whether it was the test site or not, and the degree of discomfort of the test, the degree of understanding of the breathing guidelines, and the satisfaction of the test description were improved and the score scale was improved before and after the description of the guide. Non-English-speaking foreign visitors were more satisfied with explanations in their own text than in English or Korean, and the method was also able to conduct effective inspections by informing the foreign guests when to control their breathing by using the lighting signals in the laboratory. In the future, the quality of medical services and imaging medical examinations can be improved only when communication methods are implemented from various perspectives, such as developing various language interpretation programs, developing guides for various test sites, and developing tools and improving foreign language skills of radiologists and medical staff. There will be. In the future, it may be used as a basic resource to prepare a manual that can be used to examine non-English speaking foreigners who do not understand English or Korean in other radiology labs.

The "fourth industrial revolution" is changing society as a whole. Public innovation is needed to enhance national competitiveness. Amid these times' demands, the "maker movement," a new form of DIY movement that has revived since 2000, is regarded as a "popular innovation activity" that can respond to changing needs. In particular, "Makerspace," a significant activity area for the maker's movement, is drawing attention as a place where "Maker" shares each other's knowledge and resources, and share results. Makerspace has recently expanded its functions into a 'public innovation platform' or (preparation) start-up preparation space for start-ups. South Korea has also supported various types of "Makerspace" since 2010 as a policy for fostering an innovation base. The Ministry of Small and Medium Venture Business has been pushing for expansion of Makerspace since 2018 and is providing support by dividing it into "general rap" and "professional wrap" and "zero to Maker" spaces for novice makers in the beginning and necessary stages of makers, while "professional rap" is divided into "Maker to Maker" spaces for professionals. This study is about Makerspace, space where makers are active among the topics related to manufacturers. Thus, in this study, significant domestic and international studies related to Makerspace have been investigated so far, and trends in related studies have analyzed. Based on this, the research needs and specifics of Makerspace, which has recently expanded its role and functions. In particular, the Commission intends to present the need for research on Makerspace and specific areas of study from a start-up management perspective to promote qualitative growth of Makerspace, which is changing into a popular innovation platform in the era of the fourth industry, and inducing a start-up management interest in new manufacturing industry types.

Shorelines should be extracted with consistency because they are the reference for determining the shape of a country. Even in the same area, inconsistent minimum vertex intervals cause inconsistencies in the coastline length, making it difficult to acquire reliable primary data for national policy decisions. As the shoreline length cannot be calculated consistently for shorelines produced by determining the arbitrary distance between points below 1m, a methodology to calculate consistent shoreline length using the minimum vertex interval is proposed herein. To compare our results with the shoreline length published by KHOA(Korea Hydrographic and Oceanographic Agency) and analyze the change in shoreline length according to the minimum vertex interval, target sites was selected and the grid overlap of the shoreline was determined. Based on the comparison results, minimum grid sizes and the minimum vertex interval can be determined by deriving a polynomial function that estimates minimum grid sizes for determining consistent shoreline lengths. By comparing public shoreline lengths with generalized shoreline lengths using various grid sizes and by analyzing the characteristics of the shoreline according to vertex intervals, the minimum vertex intervals required to achieve consistent shoreline lengths could be estimated. We suggest that the minimum vertex interval methodology by quantitative evaluation of the determined grid size may be useful in calculating consistent shoreline lengths. The proposed method by minimum vertex interval determination can help derive consistent shoreline lengths and increase the reliability of national shorelines.

This study examined the effect of moisture level at ensiling on fermentation characteristics of barley and rye silage. The moisture levels, 60 (low; LM), 70(medium; MM) and 80% (high; HM), were controled by adding water or pre-wilting. Barley silage had higher pH and latate:acetate ratio in LM than the other treatments, but those of rye in MM were higher. The concentrations of lactate, total FA and acetate in HM were higher than the other treatments, but propionate concentration in LM was higher than HM. Total N concentrations of barley and rye were highest in MM and LM, respectively. The $NH_3-N$ concentration and total N:$NH_3-N$ ratio of barley were higher in HM than those in LM and MM. With increasing moisture content, buffering capacity of barley and rye silages increased, whereas decreased by increase of pH. There was a negative correlation between moisture content vs. pH of barley and rye silages. However, moisture content vs. the concentrations of total VFA and $NH_3-N$ and the ratio of total N:$NH_3-N$ had a positive correlation. Tn conclusion, the ideal moisture content of barley and rye for silage was 70-80%, but silage quality could be rapidly decreased by pre-wilting to 60% moisture content.

In this study, a total of 16 conjugated linoleic acid (CLA) producing lactic acid bacteria (LAB) were isolated from fermented foods. Among those strains, the S48 and P1201 strains were capable of producing higher CLA contents than other LABs. The two strains were classified as Lactobacillus plantarum based on morphological, physiological, chemotaxonomic, and molecular-genetic properties. The survival rates of these strain appeared to be 59.57% and 62.22% under artificial gastric conditions after 4 h at pH 2.5, respectively. These strains produced the cis-9, trans-11, and trans-10, cis-12 CLA isomers from 8% skim milk medium supplemented with the different free LA concentration at $37^{\circ}C$ for 48 h and the production of two CLA isomers constantly increased in the growth until 48 h of incubation. After 48 h of fermentation, the levels of CLA appeared highest in steamed soy-powder milk than fresh and roasted soy-powder milks. In particular, the CLA contents were produced $183.57{\mu}g/ml$ and $198.72{\mu}g/ml$ from steamed soy-powder milk after fermentation (48 h) with S48 and P1201 strains, respectively.

This study was conducted to investigate the effect of single or mixed supplementation of bacterial and fungal phytase using 45-wk-old 450 Hy-Line Brown laying hens housed in individual cages for 12-wk period. The birds were reallocated to have similar egg productivity by examining the egg production for one wk before starting the experiment. Two sources of phytase, bacterial (BP) and fungal (FP), were used either in single or mixture to determine the effects of these phytase. Five dietary treatments consisted of control (BP 0, FP 0), T1 (BP 300, FP 0), T2 (BP 300, FP 300), T3 (BP 300, FP 3000), and T4 (BP 0, FP 3000). The DPU was used for phytase activity in this experiment. The nonphytate phosphorus (NPP) content of control was 0.30%, and those of phytase treatments were set to 60% of the Control. Experimental diets were fed ad libitum throughout the experimental period. The lighting schedule of 17L7D was employed. The egg production was not different between control and bacterial phytase treatments, but the T4 showed significantly low productivity compared to control (P<0.05). No difference was found in average egg weight among all treatments. The daily egg mass did not show any statistical differences among all treatments: however, it was significantly low in T4 compared to ther control during the latter half of the experiment (P<0.05). No significant difference was found among treatments in terms of feed intake, feed conversion and egg quality. The digestibilities of dry matter, crude protein, and fat digestibility were similar regardless of the treatments. No significant trends were detected in Ca and P availability. In conclusion, the BP level of 300 DPU contributed to achieve 40% reduction of recommended nonphytate phosphorus addition. The synergistic effect of bacterial and fungal phytase was not confirmed.

The purpose of this study was to investigate the unstable plate system for the advanced balance ability. 7 male volunteers (age $33.7{\pm}1.2$ years, height $174.7{\pm}3.8cm$, weight $86.0{\pm}3.6kg$, BMI $28.2{\pm}2.0kg/m^2$) performed the partial squat motion on the shape of CAP type(${\cap}$) and BOWL type(${\cup}$) plate system. The range of motion (ROM) and muscle activation were acquired by the motion analysis system and the EMG system. Results of ROMs of the CAP type plate system were shown the widely range of the deviation in the ankle joint on the sagittal plane (sagittal plane - hip joint $10.7^{\circ}$ > $5.4^{\circ}$, knee joint $16.3^{\circ}$ > $6.4^{\circ}$, ankle joint $18.8^{\circ}$ > $6.3^{\circ}$ ; transverse plane - hip joint $3.5^{\circ}$ > $1.8^{\circ}$, knee joint $5.3^{\circ}$ > $3.4^{\circ}$, ankle joint $11.3^{\circ}$ > $5.3^{\circ}$ ; frontal plane - hip joint $0.9^{\circ}$ > $0.5^{\circ}$, knee joint $0.8^{\circ}$ > $0.6^{\circ}$, ankle joint $4.8^{\circ}$ > $3.7^{\circ}$). Muscle activation results of the CAP type plate system were indicated higher in major muscles for balance performance than the BOWL type plate system (vastus lateralis 0.90 > 0.62, peroneus longus 0.49 > 0.21, biceps femoris 0.38 > 0.14, gastrocnemius 0.11 > 0.05). These findings may indicate that the CAP type plate system would expect better effectiveness in perform the balance training. This paper is primary study for developing balance skills enhancement training device.
