In this study, a real-time surveillance system using Internet of Things technology is proposed for vaccine cold chains. This system fully visualizes vaccine transport and storage. It comprises a 4G gateway module, lowpower and low-cost wireless temperature and humidity collection module (WTHCM), cloud service software platform, and phone app. The WTHCM is installed in freezers or truck-mounted cold chain cabinets to collect the temperature and humidity information of the vaccine storage environment. It then transmits the collected data to a gateway module in the radiofrequency_physical layer (RF_PHY). The RF_PHY is an interface for calling the bottom 2.4-GHz transceiver, which can realize a more flexible communication mode. The gateway module can simultaneously receive data from multiple acquisition terminals, process the received data depending on the protocol, and transmit the collated data to the cloud server platform via 4G or Wi-Fi. The cloud server platform primarily provides data storage, chart views, short-message warnings, and other functions. The phone app is designed to help users view and print temperature and humidity data concerning the transportation and storage of vaccines anytime and anywhere. Thus, this system provides a new vaccine management model for ensuring the safety and reliability of vaccines to a greater extent.

Leaves are an important organism for photosynthesis and transpiration. The shape of leaf is crucial factor affecting plant architecture. V-shape leaf rolling is enhancing canopy photosynthesis by increasing the CO₂ penetration and the light capture by reducing the shadow between the leaves. Therefore, moderate leaf rolling is thought to more high grain yield per area than flat leaf. We investigated 278 KRICE_CORE accession's Adaxial Leaf Rolling Index (LRI) in first heading using the following equation. For each accession, genomic DNA was used for sequencing. We sequenced the genomics with ~8 X coverage to detect SNPS. Raw reads were aligned against the rice reference (IRGSP 1.0) for SNP identification and genotype calling. To generate genotype data for GWAS, SNPs were filtered with minor allele frequency 0.05. Finally, 841,134 high-quality SNPs were used for our GWAS. The significant threshold was -log10(P)>7.23. From the results, 2 significance SNP were detected. Considering the LD block of 250kbp, 60 candidate gene were selected including Hypothetical gene and Conserved gene. In this poster, we analyzed candidate gene affecting adaxial Leaf Rolling through single-trait GWAS.

Nowadays, vessel's size is tending to bigger, Therefore port facilities are developed according to this trend, which has been shown in the competition of Hub-Port among the main ports such as Port of Busan and Port of Shanghai. However there are the limited number of large containerships more specifically so 70% of the total ships calling at Busan Port are small and medium sized ships which are less than 20,000 ton As a result, it is necessary to consider the handling facilities of these ships which had been disregarded The big size of facilities increases handling cost bemuse of high investment so it is possible for small and medium sized ships to have disadvantages financially and avoid calling. In this paper, we estimate the propriety of utilization of crane and labor according to the size of vessels after analyzing time value cost, reflecting the size of vessels, size and number of crane and labor structure, and container handling cost value.

The musical characteristics of Fishing songs in North Korean which recorded on Anthology of North Korean Folk Songs were examined in this paper. The results are as follows. Among Fishing songs in North Korea, there are "Rowing Song," the "Song for Hauling Nets," and the "Song for Picking Up Fish" in songs related to walleye pollack fishing and in songs related to croaker fishing, the "Song for Dropping Anchor" and the "Full-Load-of-Fish Song" in songs related to croaker fishing, the "Song for Weighing Anchor," the "Song for Shaking Fish," the "Full-Load-of-Fish Rowing Song," and the "Song for Hanging Walleye Pollack" in songs related to walleye pollack fishing. There are the "Song for Setting a sail" and the "Song for catching shells" in Fishing songs in North Korea, too. In the rhythmic elements of Fishing songs in North Korea, the tempo of the "Songs for Setting a sail" is moderato, and that of the "Songs for Picking Up Fish" of songs related to anchovy or herring fishing is quite slow. "Rowing Songs"(croaker fishing) have various tempos but faster than moderato, and usually get faster and faster as time goes by. Most songs have 4/♩. time and there are some of 2, 3 or 5 time. Some songs use irregular time or 6 time overlapping 2 beats. The mode Menari is the most common tonal system used in fishing songs of North Korea. And the mode Susimga, the mode Changbutaryeong, the mode Nanbongga, and the mode Odolttogi are also used in the tonal system of Fishing songs in North Korea. There are shoutting intonations that have indefinite pitch, too. Modulation or interaction by the mode Changbutaryeong appeared in songs of the mode Menari. There is a tendency to favor a certain tonal system by category. Responsorial form is mostly used, but in the most cases, they were sung in solo. In responsorial songs, several calling songs overlap with the responding songs. Durchkomponiert form is sung by antiphon or in solo, but the case sung in solo originally seems to have been sung by antiphon or unison, if we consider the procedure of the work. The "Song for Picking Up Fish" of Seonbong-gun of North Hamgyeong Province and Yangyang-gun of Gangwon Province, the "Full-Load-of-Fish Song-Bongjuktaryeong" of Jeungsan-gun of South Pyeongan Province and "Full-Load-of-Fish Song-Baechigisory" of Taean-gun of South Chungcheong Province, "Rowing Song" of Nampo City and Ganghwa-gun of Gyeonggi Province are resembled. In neighboring areas, even if the songs of different categorys, sometimes share a same melody. In a certain category, sometimes a same melody is shared to a considerable distance. It was first identified that in anchovy or herring fishing or dybowskii' sand eel fishing, the "Song for Picking Up Fish" is widely shared in the East Sea Coast area.

The present study aimed to identify the influence of climate change on mating songs of Cicadidae in a phenological perspective. The research sites were located in the central part of the Korean peninsula in which phenological observations by the Meteorological Office are made. The material provided by the Meteorological Office was used for long term phenological analysis. The findings demonstrated, First, the phenological monitoring of cicada is an effective index to detect ecological changes due to climate change, thus indicating the importance of long term phenological investigations for future studies. Second, the analysis on the phenological changes of H. fuscata presented a trend in which the first songs were made at increasingly earlier and later dates, respectively. The phenological data on H. fuscata and average temperatures exhibited a significant negative correlation between the initial mating song period and the average temperatures of June. Furthermore, there was also a significant negative correlation for precipitation in October with the end time and total duration of H. fuscata song. Third, in the regression analysis of the start of H. fuscata song and meteorological factors in Seoul, increasing average air temperature in spring (March to June), which includes June, was associated with an earlier start time of H. fuscata song, with calling starting approximately 3.0-4.5 days earlier per $1^{\circ}C$ increase. Fourth, in the regression analysis of the end of H. fuscata song and meteorological factors in Seoul, increased mean precipitation in October was associated with an early end time and an overall reduction in the length of the song period. The end time of song decreased by approximately 0.78 days per 1mm increase in precipitation, and the total length of the song period decreased by 0.8 days/1mm. This research is important, as it is the initial research to identify the phenological changes in H. fuscata due to climate change.

Background : Hospitals(Health care providers) are under tremendous pressure to meet consumer demands in order to compete in the rapidly changing health care arena. Through evaluating patient satisfaction, hospitals(health care providers) can learn what the consumer Wants from the health care system. Timely feedback is necessary. The purpose of this study is to evaluate patients' hospital experience and satisfaction using telephone interview and to study the usefulness for telephone interview at assessing patient satisfaction. Method : The 846 patients who were discharged from September 17, 1996 to October 11, 1996 were targeted were telephoned. The informations gathered telephone survey were processed by computer and analyzed for the patient satisfaction, contributing factors. Result : The 846 patients who were discharged from September 17, 1996 to October 11, 1996 were called and 197 patients(23.3%) were successful interviewed. 51.3 percent of respondents were male and mean age is 39 years mean LOS(length of stay) is 13 days and 110(56.1%) patients were admitted by outpatients clinic. The mean calling-time is 5.5 minutes. There is no significant difference between interviewers(telemarketer) in patients satisfaction. Seven telephone interviews are possible by interview a day. There in no significant difference between groups in patients satisfaction in length of stay, path of admission, the interval between discharge and interview. 97.5 percent of respondents were satisfied with telephone interview and 81.7% were satisfied with overall satisfaction and 79.4 % of respondents were good response in interviewers' conclusion. Of six variables that were found to be correlated with telephone interview and eight variables correlated with overall hospital satisfaction, a multiple logistic regression analysis revealed that two most important variables which are significantly correlated with telephone interview are to meet doctors, not ask tediously then three variables which are with overall satisfaction are doctors explain, subject response, convenient facilities. Conclusion : The patients interviewed are satisfied with telephone interview. Telephone interview is good method for assessing patient satisfaction, making high levels of patient satisfaction and for hospital marketing.

This study aims at reviewing and assessing the characteristics of the Korean Science, Technology and Innovation(STI) policy of the 2000s. Starting from the 2000s, Korea's STI policy began to show a new look as there was a clear voice calling for the new strategy creating a new technological development path and the scope of the policy was expanded to the social and quality of life issues. "Creation" and "integration" are becoming the key words of the STI policy of Korea. However, these new trends are not easy to be diffused or institutionalized because still there is the legacy of the old practice of the "catch-up" period, which focused on economic development as well as the imitation of advanced technologies. As result, the current period of the 2000s shows characteristics of a transitional period where the past and the future coexist.

Since the 2009 pandemic human H1N1 influenza A virus emerged in April 2009, novel reassortant strains have been identified throughout the world. This paper describes the detection and isolation of reassortant strains associated with human pandemic influenza H1N1 and swine influenza H1N2 (SIV) viruses in swine populations in South Korea. Two influenza H1N2 reassortants were detected, and subtyped by PCR. The strains were isolated using Madin-Darby canine kidney (MDCK) cells, and genetically characterized by phylogenetic analysis for genetic diversity. They consisted of human, avian, and swine virus genes that were originated from the 2009 pandemic H1N1 virus and a neuraminidase (NA) gene from H1N2 SIV previously isolated in North America. This identification of reassortment events in swine farms raises concern that reassortant strains may continuously circulate within swine populations, calling for the further study and surveillance of pandemic H1N1 among swine.
