Time, place, and the high-tech industry to overcome barriers to the fusion of the so-called "smart agriculture" is changing the landscape of agriculture. Precision Agriculture's core temperature, humidity, location information, and summary information in real time, all significant ICT controlling technique. The system is a four-season container production for the mushroom cultivation temperature, humidity, illumination, self-regulation, such as carbon dioxide, the optimal environment for mushroom cultivation was implemented. Hericium erinaceum (also called Lion's Mane Mushroom, Bearded Tooth Mushroom, or Bearded Tooth Fungus) is an edible mushroom and medicinal mushroom in the tooth fungus group. Native to North America, Europe and Asia it can be identified by its tendency to grow all the spines out from one group (rather than branches), long spines (greater than 1 cm length) and its appearance on hardwoods. About 40 days of incubation 1.5kg oak sawdust was used as the test medium bag. The humidity was maintained more than 85~95% and temperature was 18~20°C, and CO2 density was 500~1,000ppm. The days for primordium formation showed us 6~12 days. The amount of fruitbody production was 110~260g per bag. This technique to establish new community support program in conjunction with the international movement, domestic sales and exports are also planned.

N/A Objectives: Cardiogenic shock resulting from acute myocardial infarction is a serious complication with high mortality. The early identification of patients at high risk of developing post-infarction cardiogenic shock might allow early intervention in an attempt to prevent cardiogenic shock and to reduce the mortality due to cardiogenic shock. The aim of the present study was to examine the risk factors of inhospital development of cardiogenic shock among patients with acute myocardial infarction. Methods: We studied 152patients with acute myocardial infarction who were admitted to Kang-Nam St. Mary's hospital within 24hours after the onset of chest pain and did not have cardiogenic shack on admission between March 1991 and May 1994. Clinical data of these patients were analyzed. Results: Of 152patients, 17(11.1%) developed cardiogenic shock during their hospital stay. Cardiogenic shock developed in 53% of cases more than 24hours after admission. 82.4% of patients with cardiogenic shock died whereas a 6.7% in-hospital mortality was found among patients without cardiogenic shock. Multivariate regression analysis that controlled for variables affecting incidence of postinfarction cardiogenic shock showed that independent risk factors for in-hospital cardiogenic shock were history of myocardial infarction (adjusted relative odds[RO]=5.294, 95% confidence interval[CI]=2.149 to 13.041); heart failure on admission (RO=3.344, 95% CI=1.738 to 6.432); hyperglycemia (>180mg/dl) in non-diabetic patients (RO=3.270, 95% CI=1,590 to 6.727); age over 70 year old (RO=2.912, 95% CI= 1.816 to 4.668); ST deviation over 4mm (RO=2.417, 95% CI=1.225 to 4.767); peak LDH level greater than 1600U/ml (RO=1.154, 95% CI=1.080 to 1.233). Patients with one independent risk factor had an estimated probability of 10.5% for developing inhospital cardiogenic shock; patients with two independent risk factors, 48.5%, patients with three risk factors, 65.0% patients with four risk factors, 65.7% patients with five risk factors, 67.2%. Conclusion: Of post-infarction cardiogenic shock during admission, 53% developed more than 24hours after admission. The more independent risk factors on admission for inhospital cardiogenic shock patients with acute myocardial infarction had, the more likely in-hospital cardiogenic shock developed.

There are many dangerous elements in industrial field. Many works are exposed to the danger. Therefore, industrial field has need of disaster prevention system. In this paper, we propose a disaster prevention system for preventing accidents which can occur in industrial field. A disaster prevention system consists of monitoring system, sensing system and kiosk station and information terminal. Monitoring system manages an industrial field and it transmits information in the worker. Sensing system detects the disaster elements using temperature, flame, smoke, wind direction, wind velocity and infrared ray sensor. Kiosk station controls entrance admission to workplace. It provides field information to worker. Information terminal provides field information, worker location and facility records. To prevent accidents in industrial field, they support safety control strategy that provides overall information on various multi misfortune situations.

Surface-diffusion-limited growth of atomically thin WS2 crystals from core-shell nuclei

<P>Atomically thin transition metal dichalcogenides (TMDs) have recently attracted great attention since the unique and fascinating physical properties have been found in various TMDs, implying potential applications in next-generation devices. The progress towards developing new functional and high-performance devices based on TMDs, however, is limited by the difficulty in producing large-area monolayer TMDs due to a lack of knowledge of the growth processes of monolayer TMDs. In this work, we have investigated the growth processes of monolayer WS2 crystals using a thermal chemical vapor deposition method, in which the growth conditions were adjusted in a systematic manner. It was found that, after forming WO3-WS2 core-shell nanoparticles as nucleation sites on a substrate, the growth of three-dimensional WS2 islands proceeds by ripening and crystallization processes. Lateral growth of monolayer WS2 crystals subsequently occurs by the surface diffusion process of adatoms toward the step edge of the three-dimensional WS2 islands. Our results provide understanding of the growth processes of monolayer WS2 by using chemical vapor deposition methods.</P>

Backbone NMR Assignments of a Putative p53-binding Domain of the Mitochondrial Hsp40, Tid1

Jo, Ku-Sung,Sim, Dae-Won,Kim, Eun-Hee,Kang, Dong-Hoon,Ma, Yu-Bin,Kim, Ji-Hun,Won, Hyung-Sik Korean Magnetic Resonance Society 2018 Journal of the Korean Magnetic Resonance Society Vol.22 No.3

Human Tid1, belonging to the family of the Hsp40/DnaJ, functions as a co-chaperone of cytosolic and mitochondrial Hsp70 proteins. In addition, the conserved J-domain and G/F-rich region of Tid1 has been suggested to interact with the p53 tumor suppressor protein, to translocate it to the mitochondria. Here, backbone NMR assignments were achieved for the putative p53-binding domain of Tid1. The obtained chemical shift information identified five ${\alpha}$-helices including four helices characteristic of J-domain, which are connected to a short ${\alpha}$-helix in the G/F-rich region via a flexible loop region. We expect that this structural information would contribute to our progressing studies to elucidate atomic structure and molecular interaction of the domain with p53.

CHINA s Economic Growth and the Role of Criminal JUSTICE Agency : A Comparison between Ministry of Public Security of the People’s Republic of CHINA and the National Police Agency of KOREA

Kang Ho-gu,Wang Lin-Lin,Jo Sung-gu J-INSTITUTE 2016 Robotics & AI Ethics Vol.1 No.1

While China achieved the fastest economic growth in the world since it actively adopted market economy after its economic reform, it also saw increase in various crimes. There is very little research done on the Minis-try of public security of the people’s republic of China, but based on the previous research, the types of crimes can be summed up as following. Firstly, the crimes in China are becoming organized and are becoming a commercialized profession. Secondly, the Chinese crime organizations are covertly managing their fund circulations through 3rd party bank accounts and virtual accounts on the internet. Thirdly, every time a new type of industry emerges, a new type of crime exploiting the industry grows rapidly. Meanwhile, under the Chinese planned economy, the MPS had a major role on many components of social life in China. For example, the relationship among the MPS, the prosecutors and the court clearly shows that the MPS is relatively higher in status, and its authority is encroaching the Ministry of Civil Affairs of the People’s republic of China, China administration of Taxation, and China Administration of Industry and Commerce, and is in need for a change through a reform. Meanwhile, after achieving a rapid economic growth since the 1960’s (83.1%), South Korea ranked first in human rights protection and international policing cooperation in the “Crime Index for Country 2015 Mid-Year”. The authority of China’s MPS is a part of national administrative authority, which comes from the people. Therefore, one must consider whence the authority exercised by the MPS derives. Here are some problems of MPS identified in this research. Firstly, the Chinese MPS is inefficient in tasks that utilizes human resources within the jurisdiction. Secondly, it is difficult to communicate the information related to crimes collected by the MPS efficiently. Thirdly, the MPS has limited ability in cutting the criminal funds. Fourthly, the MPS fails to fully cooperate in criminal investigations. Fifthly, MPS demonstrates an incomplete cooperation in Crime prevention tasks. Therefore, to keep up with the rapidly grown economy, various discussions on the role of MPS and an inter-national cooperation on the safety of people will become necessary.
