This study aimed to analyze open access features of 1,890 Korean scientific journals registered in the Korea Citation Index (KCI). To this end, this study classified open access features of the target scientific journals into two main aspects, free access and free redistribution. The analysis results indicated that the target scientific journals had strong free access aspects. Based on websites, 67% of the target scientific journals allowed for free access without a login process and based on free database, 48% provided free access. On the other hand, the target scientific journals had weaker free redistribution aspects compared to their free access aspects. Only 14% of them offered the CC (creative commons) license. Another finding was that there were clear differences in open access aspects by academic field. Medicine, pharmacy, natural science, agriculture, fisheries, oceanography, and engineering had stronger open access aspects than humanities, sociology, arts, physical education, and interdisciplinary science. It appears that the difference was caused by the presence or absence of organizations supporting distribution of scientific journals of the fields concerned. To narrow the gap, it is recommended that the open access governance system is established to set up open access policies for Korean scientific journals regardless of academic fields and to support them.

Emotion is composed of various feelings such as pleasure, sorrow, comfortability, and so on. The complicated process of the measurement has long been recognized as a major hindrance for the studies of emotion. Previously, individuals' emotion has mainly been measured by means of self-report, interview, EEG (electroencephalogram), ECG (electrocardiogram), EOG (electroculography), and body temperature. With thanks to nano/micro technologies, the possibility in the development of emotion-on-a-chip (EOC) has begun to be proposed. EOC will make it possible to analyze one's psychological status by taking a drop of blood. Discovery of emotional biomarkers in body fluids, understanding of the correlation between those biomarkers and the results from brain science are prerequisites to validate the EOC technology. In this paper, paper microfluidics are introduced as a good candidate for the EOC. As paper microfluidics is cost-effective and easy to use it is expected to be a useful device for the emotion measurement. We present the design and fabrication process for the simple paper-based microfluidic device and discuss the possible application in the field of measuring the human emotion.

When preparing for a blood transfusion, the presence and types of unexpected antibodies should be identified through screening tests. Using the DiaMed-ID system, antibody identification among unexpected antibody screening tests performed at a university hospital in Daejeon area for two years from January 2016 to December 2017 were limited to 55 patients and were predominantly women. A total of 36 patients (65.5%) belonged to the Rh group, 7 (12.7%) patients to the Lewis group, 4 (7.3%) patients to the Kidd and Duffy groups, 3 patients (5.5%) to the MNS group, and 1 (1.8%) to the Rh+Kidd combined group. In the Rh group, 19 (34.5%) patients had Anti-E single antibody, 5 (9.1%) patients had Anti-D single antibody, 4 (7.3%) patients had Anti-E/-c, 4 (7.3%) patients had Anti-C/-e, and 1 (1.8%) patient had $Anti-E/-c/-Jk^b$. In the Lewis group, three (5.5%) patients had both $Anti-Le^a$ and $Anti-Le^b$. In the Kidd group, one (1.8%) patient had $Anti-Jk^a$ and three (5.5%) patients had $Anti-Jk^b$. In the Duffy and MNS groups, only single antibody was found: one (1.8%) patient with $Anti-Fy^a$, three (5.5%) patients with $Anti-Fy^b$, two (3.6%) patients with Anti-M, and one (1.8%) patient with Anti-S. This study reflects the recent frequencies and distributions of unexpected antibodies in Daejeon, which would be helpful for the efficient preparation for transfusions.

Recently, developing medical devices have a tendency becoming the module for satisfying user's mutual complex needs. Because the most effective method for the observation of patients condition a diagnosis and a treatment is collecting data from various devices and controling operation following it. Module tendency is more popular due to manage easily totally many individual systems. This study implemented communication protocol to control by one control system connecting modular medical devices. Implemented system consist of one master module controlling all module and managing communication and many Slave modules. Communication between each modules introduced SPI(Serial Peripheral Interface) among many synchronous serial communication methods for the exact transmission and receipt of data. All communication executes by packet format. This can detect error. And, this protocol introduced PNP(Plug And Play) function that auto-detect connecting or removing module during running. This protocol exactly transmitted and received in faster speed more than 1Mbps. And in practical application to the ventilator this confirmed to give and take real-time data. And various functions by th central control system is implemented in this protocol.

The purpose of this study was to examine the association metabolic syndrome with sarcopenia in Korean stroke patients. We used the Korean National Health and Nutrition Examination Survey data from 2008 to 2011 and enrolled a total of 316 stroke patients older than 40 years. Data were analyzed by Rao-Scott ${\chi}^2-test$, generalized linear model and composite sample multiple logistic regression. The prevalence of sarcopenia was 47.3% in men and 46.3% in women. The prevalence of metabolic syndrome was 50.3% in men and 73.6% in women. After adjusting for age, smoking status, alcohol consumption, exercise, education, income, sroke sequla and stroke duration, men with sarcopenia had increased risk of metabolic syndrome (95% CI: 2.454-18.482, p<.001). This finding can be used to develop evidence-based health promotion program to prevent stroke reccurance for stroke patients.

Pseudomonads cause bacterial brown blotch disease, which causes great damage to the common mushroom Agaricus bisporus. The tolerance of A. bisporus to pseudomonads was tested and found to not be correlated with mycelium growth ability. The offsprings of the tolerant strain (ASI1085) to pseudomonads were not as tolerant as their parents in the mycelium stage. But, tolerance decreased compared to mycelium in the fruiting body. The offsprings of the weakly tolerant strain (ASI1321) were even more weak in the mycelium stage. It is presumed that the tolerance of the parents is transferred to later generations. The tolerance in the mycelium was not correlated in the fruiting body. Therefore, the browning of the fruiting body is thought to be induced by other factors. Pseudomonas tolaasii caused higher browning than Pseudomonas agarici. Pseudomonas reactans did not have a significant effect on the mycelium, but affected the browning of the fruit bodies. P. agarici had higher ability to inhibit mycelium growth than fruiting body growth.

The studied Fe-REE ore consists of magnetite, ankerite, siderite, magnesite and strontianite as the major constituent, and monazite, columbite, fergusonite, apatite, aegirine-augite, Na-amphibole, pyrite, chalcopyrite, sphalerite, molybdenite and barite as accessaries. Wall rock of ore deposits is replaced to fenite due to Na-metasomatism and mainly consists of sugary albite and Na-amphibole. Monazite $Ce_{0.49}La_{0.31}Pr_{0.14}Nd_{0.03}Gd_{0.03})PO_4$ is the main mineral for REE deposit and shows myrmekitic intergrowth with strontianite $Ca_{0.02-0.16}Sr_{0.84-0.98}CO_3$ and is corroded by carbonate minerals. Mineral forming sequence can be divided into early and late periods by the development of microfractures. The early period minerals such as magnetite, ankerite, magnesite, monazite and apatite show well developed networks of microfractures due to cataclastic deformation caused by enriched $CO_2$ gas in melts during emplacement. The late minerals of columbite, fergusonite, siderite molybdenite, chalcopyrite and sphalerite formed after the brecciation event and have little micro-fractures. Ankerite, magnesite, monazite, strontianite, barite and pyrite seem to be formed continuously from the ealy to the late period since they show textures both with well developed fractures and also with little fractures. Mineral chemistry, mineral assemblages such as various carbonate minerals, magnetite, REE minerals of monazite and fergusonite, Sr mineral of strontianite, and Nb minerals of columbite, myrmekitic texture of monazite and ankerite, and well developed fenite along ore deposits observed from this studied area strongly indicate that this Hongcheon Fe-REE ore deposits are formed from carbonatitic melt and its rock type is late differentiated Fe-carbonatite or ankerite-carbonatite.

This study aimed to assess the influence of burnout with satisfaction of basic psychological needs among nurses. From oct, 25, 2013 to nov, 25, 2013, participants included 160 nurses from 6 major general hospital located in urban areas in Korea. Data for basic psychological needs and burnout were collected through a self-reported questionnaire and were analyzed with independent t-test and analysis of variance, Pearson's correlation analysis, and multiple linear regression analysis. This study shows negative correlations between burnout and autonomy(r=-.45, P<.001), competency(r=-.52, P<.001), relatedness(r=-.49, P<.001). The variables predicting burnout were autonomy(${\beta}=-.26$), competency(${\beta}=-.30$), relatedness(${\beta}=-.12$), age(${\beta}=-.17$), number of service years(${\beta}=.09$). These variables accounted for 34.3% of the variance of burnout in nurses. Our results indicated that it is necessary to increase basic psycological needs to decrease burnout. Therefore nursing managers should develop programs in order to increase autonomy, relatedness and competency.

In recent years, activities have become more important in political activities and participation in policies. Therefore, the level of digital informatization can affect the participation in policy in the online environment. In this study, we examined how the policy activities of the disabled have a relationship with the informatization level. To this end, we analyzed the relationship between the level of digital informatization and the level of satisfaction with policy activities based on the results of the digital divide survey of 2017. The results of this study are as follows: First, it shows that the disabled people have a positive relationship with the digital access and policy activity satisfaction levels such as the possession of wired / wireless information devices and Internet accessibility. Second, it is found that digital information capacity level and income level such as PC utilization ability and mobile digital device utilization ability have a positive (+) relationship. Third, as the level of digital information utilization such as wired and mobile Internet usage increased, the level of satisfaction with policy activities also increased positively. This suggests that the government needs various information policy to increase the level of digital informatization of the disabled.

This experimental research explores the effect of background music of TV documentary which can be classified as channel factor in the field of media effect, on audience's recall memory, flow, arousal of interest, evaluation of documentary. Most previous researches of media effect focused on the effect of sender factor and message factor on audience's memory, understanding, acquirement of knowledge, attitude, action. However the number of researches on the effect of background music on audience's various dependent variables is extremely limited, especially it is very difficult to find studies on the effect of background music of TV documentary on audience. Therefore this research tries to find the effect of background music of TV documentary on audience's recall memory, flow, arousal of interest, evaluation. For this research of experiment, 2 groups of subjects composed of 101 university students were exposed to 2 different video clips of TV documentary, one with background music, the other without it, After this experiment, Questions which were designed to measure audience's recall memory, flow, arousal of interest, evaluation were asked and analysed. This research found that background music of TV documentary increased audience's flow, degree of interest and raised evaluation, However meaningful effect of background music on audience's recall memory was not found.
