  • The Internet of Medical Things (IoMTs) are to be considered an investment and an improvement to respond effectively and efficiently to patient needs, as it reduces healthcare costs, provides the timely attendance of medical responses, and increases the quality of medical treatment. However, IoMT devices face exposure from several security threats that defer in function and thus can pose a significant risk to how private and safe a patient's data is. This document works as a comprehensive review of modern approaches to achieving security within the Internet of Things. Most of the papers cited here are used been carefully selected based on how recently it has been published. The paper highlights some common attacks on IoMTs. Also, highlighting the process by which secure authentication mechanisms can be achieved on IoMTs, we present several means to detect different attacks in IoMTs

  • 최근의 IoT 기술의 발전은 다양한 형상, 네트워크 특징 및 서비스 아키텍쳐를 가지는 IoT 기기, 서비스 및 단말을 활용한 서비스의 발전을 가져오고 있다. 특히 OneM2M, OCF 등의 표준기구등은 다양한 IoT 기기 및 서비스 아키텍쳐에 대한 정의를 최근 수년간 진행해 오고 있으며, 이러한 IoT 서비스는 단순히 기기의 원격 상태 확인 및 제어 뿐만 아니라, 클라우드 및 AI 기술과의 연계를 통하여 그 서비스 영역을 지속적으로 확장 중에 있다. 이 중 Internet of Media Things 표준은 다양한 미디어 기반 서비스를 Thing으로 표현하여 다양한 Thing과의 연계 방안을 제시하고 있다. 본 논문에서는 기존에 다양한 기법을 통하여 연구 및 구현되고 있는 영상 기반 서비스를 Internet of Media Things 표준 기반으로 구현하기 위한 방법을 제시한다. 기존 영상 분석 기술은 대부분 정확도의 향상에 그 목적을 가지고 있어 서비스 형태로 제공하고 타 기기와의 연계성을 제공하기 위한 추가적인 기술간 연계가 필요하다. 본 논문에서는 Yolo v3 기반의 Face Detection 기술에 대하여, 해당 기술을 Internet of Media Things 표준으로 표출하기 위한 요구사항을 파악하고 실제 구현하기 위한 방안에 대하여 검토한다.

  • MPEG-IoMT(Internet of Media Thing)은 국제 표준으로서, 미디어 사물 간 데이터를 주고 받을 수 있도록 데이터 포맷과 API를 정의하고 있고 있기 때문에 본 표준을 통해 호환되지 않는 모든 미디어 사물 간에도 쉽게 연결될 수 있을것이다. 하지만, 현재 여러 미디어 사물 간 자동화된 연결에 대한 표준은 존재하지 않아 미디어 사물을 연결하고자 할 때는 사용자가표준 API를 통해 직접 연결을 해야 하는 단점이 있어 미디어 사물 간 자동 연결이 가능하게 특정 기능에 대한 필요한 미디어 사물을 제공할 수 있는 서술 도구에 대한 필요성이 나타나고 있다. 따라서, 본 논문에서는 Finite Machine 기반으로 미디어 사물 간 자동화된 연결을 제공할 수 있는 Mission Diagram 서술 도구에 대해 제안한다.

  • PURPOSE: The aim of this study was to verify the effect of trunk strengthening exercise using oscillation by comparing trunk muscle thickness, as well as balance of healthy adults during exercises performed with an oscillatory device and non-oscillatory device. METHODS: Twenty-two participants were randomly assigned to one of two groups: the trunk strengthening exercise using oscillation (TSEO) group (n=11) or the trunk strengthening exercise using non-oscillation (TSEN) group (n=11). Subjects in all groups performed the exercises three days per week for 6 weeks. All subjects performed four types of exercises: pull over, seated twist, power push, and diagonal power plank. Trunk muscle thickness of the rectus abdominis (RA), internal oblique (IO), external oblique (EO), transverse abdominis (TrA), and multifidus (MT) were measured with an ultrasonography. The balance ability were evaluated using the Romberg test with eyes open, eyes closed, one-leg standing test (OLST), and limits of stability (LOS). All tests were performed before the intervention, as well as after 6 weeks and 8 weeks of exercises. RESULTS: There was a significant difference of RA, IO, TrA, and MT according to the main effect of the time (p<.05). There was a significant difference of IO and LOS according to interaction effect between the time and group (p<.05). CONCLUSION: As intended, the cyclic forces induced by the oscillating device did increase trunk muscle thickness. However, the effect was limited and significant only for the IO muscle. Combining trunk strengthening exercise with oscillation appears to be more effective in improving dynamic balance.

  • This study was conducted for investigation of habitat and development of indoor-rearing conditions of peacock butterfly, Inachis io (Linnaeus). Three different region, Mt. Kwangduk-san, Mt. Hae-san and Mt. Taebaek-san in Kangwon-do, was selected for investigation of domestic distribution and ecological environment of peacock butterfly. In result, there are many butterflies in the only two region, Mt. Kwangduk-san and Mt. Hae-san. On 16th April, 4 overwintered butterflies were observed in Mt. Hae-san. At the end of June and early in July, 51 individual next generation's butterflies were observed in Mt. Kwangduk-san and Mt. Hae-san. For development of indoor-rearing conditions, collected each 15 male and female peacock butterflies was reared in a room condition. Female butterflies laid eggs in the egg cluster on the underside of host-plant's leaves, Urtica angustifolia Fisch., in the ovipositioning room. We took 11 egg cluster with average $404.6{\pm}23.6$ eggs. Hatchablity of eggs was 92.3%, and the eggs hatched within $5.1{\pm}0.9$ days from the day of oviposition under high temperature, long day condition($25^{\circ}C$, 14L:10D). The larval period was $18.3{\pm}1.0$ days under high temperature, long day condition($25^{\circ}C$, 14L:10D), showing 81.0% pupal ratio. The head width of each developmental larval stage were $0.37{\pm}0.01mm$(1st instar), $0.66{\pm}0.02mm$(2nd instar), $1.07{\pm}0.05mm$(3rd instar), $1.81{\pm}0.07$(4th instar), $2.76{\pm}0.08$(5th instar). The pupal period was $8.4{\pm}0.6$ days, and the emergence rate was 87.5%.

  • Internet of Media Things (IoMT) aims to provide intelligent media services to users by connecting (media) things to each other and exchanging media data. The mission given by the user is automatically executed, and intelligent media service can be provided to the user. To achieve this, ISO/IEC 23093-5 started standardization work on the mission data given by the user to the media thing and the media thing controller (MController) that controls the media things. This paper introduces the contents of ISO/IEC 23093-5.

  • A study has been done on the separation of iodide from spent pressurized water reactor (PWR) fuels and its quantitative determination using ion chromatography. Spent PWR fuels were dissolved with mixed acid of nitric and hydrochloric acids (80 : 20 molL%) which can oxidize iodide to iodate to prevent it from be vaporized. After reducing ${IO_3}^-$ ­to $I_2$ in 2.5 M $HNO_3$ with $NH_2OH{\cdot}HCl$, Iodine was selectively separated from actinides and all other fission products with carbontetrachloride and back-extracted with 0.1 M $NaHSO_3$. Recovered iodide was determined using the ion chromatograph of which the column was installed in a glove box for the analysis of radioactive materials. In practice, spent PWR fuel with 42,000~44,000 MWd/MtU was analyzed and its quantity was compared to that calculated by burnup code, ORIGEN2. The agreement was achieved with a deviation of -8.3~-0.5% from the ORIGEN 2 data, $324.5{\sim}343.6{\mu}g/g$.

  • 현재 멀티미디어는 사용자의 감성을 자극하며 몰입감과 현장감을 자아내고 극대화할 수 있는 실감 미디어(Immersive media)로 발전하고 있다. 이러한 실감 미디어 내 시청각 정보의 저장과 표현을 위한 데이터 템플릿과 인터페이스들은 상당히 많은 부분에서 표준화되어 왔지만, 이와 달리 후각, 미각, 촉각 등의 실감 정보들은 관련 표준들의 부재로 인해 많은 연구 개발에도 불구하고 해당 서비스들의 상용화가 지연되고 있는 중이다. 이 문제를 해결하기 위해 이 논문에서는 후각 미디어에 초점을 맞추어 MPEG-V 표준과 현재 진행 중인 MPEG-IoMT(Internet of Media Thing) 표준을 사용하여 미디어 사물 인터넷 내 후각 인터렉션을 위해 필요한 표준 데이터 템플릿과 인터페이스를 기술하였다.
