A home network is a typical ubiquitous computing network that consists of various consumer devices and service environments. Home networks are requiring increasingly more complicated services, such as multimedia home theater and the monitoring and controlling of heterogeneous devices. Accordingly, a mutually connecting mechanism is needed among heterogeneous devices and services redundant. The current paper presents a Multimedia Room Bridge Adapter (MRBA) system that is designed to manage heterogeneous devices and support various services. In addition, a hardware and software prototype is implemented based on the proposed architecture.

Agricultural ecosystem biodiversity monitoring and community variation analysis of insects were conducted from 2016 to 2018 in selected conventional and organic farming fields in Goesan district, Chungcheongbuk-do, South Korea. The total number of 1,125 species in 16 orders and 207 families were identified. The numbers of species collected in the locations practicing organic farming were greater than the conventional farming both in the paddy fields (564 vs. 383 species) and the upland fields (471 vs. 365 species). Among them, Hemiptera had the most abundant of species, followed by Diptera, Hymenoptera, Coleoptera and Araneae. We calculated various index values of biodiversity (diversity index H’, richness index R, evenness index J’, dominance index D, and similarity index QS) based on quantitative measurements of species and individuals collected over three years of field monitoring. Variations in biodiversity index values in different agricultural systems show that the positive effect of organic farming is to produce more biodiversity than conventional farming systems. When compared to other index results reported in Korea, Japan and China, the richness index was higher and other index values were at similar levels.

이 논문에서는 전 · 후처리기를 포함하는 고속 궤도차량의 동역학 해석 소프트혜어를 개발하였다. 궤도차량은 차체, 포탑, 마운트, 포신과 로드휠 어셈블리로 구성되어 있다. 궤도는 인장에 대하여 일정한 탄성을 가진다고 가정하여 궤도에 의한 구속력을 직접 구하여 차량의 운동방정식에 외력으로 넣어주는 방법으로 모텔링하였다. 시스탬의 운동방정식은 속도변환기법을 이용하여 조인트 좌표로 유도하였으며, 전 · 후처리기는 visual C++을 이용하여 개발하였다.

The number of databases maintained in the world is increasing rapidly. Many of these databases are huge and are therefore very difficult to manually analyze. To make it feasible to analyze databases, researchers have been developing tools for knowledge discovery in databases. This paper proposed the knowledge discovery system based on rule-based system to efficiently discover knowledge in databases.

The purpose of this study were to compare the lumbar extensor strength between laser discectomy and Non-Op patients group in HIVD before and after 12weeks training. To evaluate lumbar extensor strength of total 60 patients with HIVD, Lumbar extensor strength was measured in 20 PELD patient group. 20 OLM patient group, and 20 Non operation patient group by Medx lumbar extension machine(PELD: Percutaneus Endoscope Laser Discectomy, OLM: Open Laser Microscope). Training was conducted twice per week for 12wks and consisted of one set of 15-18 repetitions of Variable resistance lumbar extension until volitional fatigue. After 12weeks in male, Maximum voluntary lumbar extension strength was appear rate of increase 65.57% in PELD group, 51.68% in OLM group, and 70.93% in Non-op group. After 12weedks in female, appear rate of increase 61.90% in PELD group, 55.41% in OLM group, and 78.54% in Non-op group. In 3 group, Male lumbar extension strength was no statistically significant difference (P>.05). Female was statistically significant(P<.05). Male group was appear lower than Male Norms(P<.05 and female group was appear similar to and higher than Female Norms(p<.05). Lumbar flex/ext ratio of the three group was 2.48:1 pre-training and 1.558"1 post-training in lumbar flexion 72 and 0 degree. The ration of post-training was lesser than before training.

Ionic conductivities of PMMA-based polymer blends plasticized with poly (ethylene glycol) methyl ether(PEGMe) complexed with LiCLO4 have been investigated for applications in lithium battery. These solid polymer electrolytes are studied at room temperature using impedance analysis technique and FT-IR. Maximum ionic conductivity at room temperature was measured to be 5.9×10-5 S/cm in the free standing film state for PMMA concentratin of 17% w/w. The ionic conductivity decreases at higher PMMA concentration of 30% w/w, since the nonconducting area according to the phase separation of PMMA increases. The phase separation of PMMA in polymer electrolytes was shown by the absorbance variation of the carbonyl peak of PMMA.

To compare the marginal leakage of CAD/CAM-fabricated ceramic inlay, gold inlay and amalgam, forty extracted caries-free premolars were prepared with Class Ⅱ MO cavity design. The teeth were divided into four groups of ten samples each. Group 1 was restored with CAD/CAM-fabricated ceramic inlays cemented with Scotchbond Resin Cement / Scotchbond Multi-purpose plus. Group 2 was restored with gold inlays cemented with Scotchbond Resin Cement / Scotchbond Multi-purpose plus. Group 3 was restored with gold inlays cemented with zinc phosphate cement. And, Group 4 was restored with amalgam. All samples were thermocycled, and stored in 1% methylene blue. Marginal leakage was examined at four margins, that is, occlusal distal, priximal gingival, occlsal facial and occlusal lingual margins from sectioned samples under steeomicroscope(x15). The results were as follows: 1. Group 1 and 2 showed no statistically significant difference among marginal leakage at all four examined margins(p>0.05). 2. Group 3 and 4 showed significant marginal leakage at proximal gingival margin compared with other margins(p<0.05). 3. Significantly increased marginal leakage at priximal gingival, occlusal facial and occlusal lingual margins in group 3 were observed compared with other groups(p<0.05).
