In this work, we investigated the vapor-liquid equilibrium data of the system 2.methyl-1.3dioxolane - water, in order to provide elementary data for separation of 2.methyl-1.3dioxolane and water. Experiment was carried out at 30℃ and 35℃ isotherm by new head space analysis method, which was developed by ourselves. This binary system has the minimum azeotrope in both isothermal condition and has relatively large value of activity coefficient. It indicate that this system is nearly nonideal. Some model parameters, such as Wilson, NRTL, etc., were evaluated. With these parameters, each isothermal data was recalculated. We compared experimental data with recalculated data. By NRTL parameter fit experimental data best.

As modern people's interest in health grows, wearable healthcare-related technologies that can collect biometric information and receive health-related services regardless of time and place are developing. This paper proposes the healthcare system based on voice recognition function. Unlike conventional wearable healthcare systems, the proposed system provides real-time telemedicine and diagnosis and the direct connection with doctors is possible through it. And almost all functions of the application in it are operated with voice commands to lower user access barriers. Because it deals with personal information including medical information, encryption algorithms have been applied between all data movements. Finally, the healthcare system proposed in this paper is expected to increase convenience in health care and reduce the medical gap.

Recently, when being constructed the large structures, the deep excavations have performed to utilize the underground space. As the ground excavation is deeper, the damage of the adjacent structure and the ground is frequently occurred. The Analysis of the retaining structures is necessary to safety of the excavation works. There are many methods such as elasto-plastic theory, FEM, and FDM to analyze the displacement of the retaining structure. In this thesis, GEBA-1 program by the Nakamura-Nakajawa elasto-plastic method was developed. The lateral displacement of the wall was analyzed by the developed program GEBA-1, SUNEX, and EXCAD, and compared with the measured displacement by the Inclinometer. The monitored fields were three excavation work site in S-Ⅰ, S-Ⅱ, and S-Ⅲ area. Excavation method of each site is braced retaining wall using H-pile. Excavation depth is 14m, 14m, and 8.2m.

본 연구에서는 탄소/탄소 복합체의 내산화성을 증진시키기 위하여 CVD법에 의한 SiC코팅과 PCS함침법을 응용하여 실험을 행하였다. 전자현미경으로 시편의 미세구조를 관찰한 결과 CVD법에 의해서는 표면에 SiC가 고르게 증착되었으며, 함침법에 의해서는 각 탄소 섬유의 표면에 PCS가 wetting된 후, SiC로의 전이가 잘 일어났음을 확인할 수 있었고, 이로 인하여 각 섬유들의 결합력을 증대시키고 기계적물성에 증진을 가져왔음을 확인하였다. PCS 함침된 탄소/ 탄소 복합체 시편은 함침되지 않은 시편에 비해 밀도는 25%, 곡강도 값은 3.5배, 내산화성은 2.8배가 증가하는 현격한 기계적 물성이 증가함을 보였다. 이러한 증가는 CVD법에 의해 코팅된 탄소/탄소 복합체 시편 보다도 우수한 기계적 성질을 보여주었다. Applicability of SiC coating through CVD process and PCS.(polycarbosilane) impregnation for the oxidation resistance and mechanical properties of C/C composite and graphite was studied. The SiC layer coated by CVD was deposited uniformly on the C/C composite, whereas the SiC converted from PCS impregnation wetted around individual carbon fiber. The PCS-impregnated C/C composite exhibited a significant increase of bending strength in comparison with as-received C/C composite. This increase in the mechanical property could be attributed to the high bonding strength between fibers due to an impregnated SiC phase. The PCS-impregnated C/C showed 25% improvement in density, 3.5 times higher MOR and 2.8 times higher oxidation resistance compared to the as-received C/C. The increments due to PCS impregantion were more effective than CVD process.

창조적 발상을 위한 표현 기법에 관한 연구 : Presentaation기법을 중심으로

In some sence, design process can be regarded as a communication process where designer send his message through the design of product to consumer. Designer's role in this point is to properly define style, color, the way of operation and symbolic sttus of the product so that consimer, the end user can and feel as designer intended to so. However, methods for measuring consumers need were mainly developed and practiced by market researchers who speak fundamentally different language from designers who speak fundamentally different language from designers who supposedly apply information handed over from marketers for designing products. Marketers languages are verbal, quantitative, and analytic rather than visual, qualitative and holistic. Designers need the methods based on the designerly way of thinking. This thesis prposes the way to develop visual scale for evaluating the image of product design. At first, the thesis discusses the necessity, objecive, and scope of the study forming introductory part. Then design process is examined as communication process and roles of designer, product, and consumer were define under the view of communication process. Existing methods for evaluating the image were reviewed for finding disadvangages and adventages of them. Findings of existing method formed the basic for the development of visual scale. Pictures for visual scale were collected and screened out by questionnaires of university students and some statistical analyses. A set of 35 pictures were selected for visual scales. Case syudy were done for demonstrating the application and the effectiveness of visual scale. Finally findigs of the study were summarized and further prospect were proposed.

본 연구가 가축 생균제(direct-fed microbials)용 내산성 및 내담즙성이 우수한 유산균을 분리하기 위하여 실시하였다. 자돈 분변으로 분리한 유산균 중 혐기성 조건에서 성장이 우수한 8균주가 1차적으로 선발되었다. 선발 균주들 중 내산성 및 내담즙성이 우수한 JY-12 및 JY-73를 최종 선발하였다. 최종 선발 균주들을 형태학적 생리학적 특서에 따라 동정한 결과 Lactobacillus salivarius로 동정되었다. The objective of this study was isolation of acid and bile tolerant lactic acid bacteria for direct-fed microbials. Among lactic acid bacterial isolated from piglet feces, 8 strains having high anaerobic growth ability were selected. Among isolated strains, JY-12 and JY-73 strains were selected according to the acid and bile tolerant characteristics. Finally selected strain JY-12 and JY-73 were identified as Lactobacillus salivarius based on their morphological and biochemical characteristics.

The Internet of Things, the core of the Fourth Industrial Revolution, is growing by applying various technologies to various fields. Among them, smart home systems that apply IoT technology to home environments are actively being researched, and the home hub market, which is a communication medium for smart homes, is also developing at the same time. However, the security damage from cyber attacks, which are vulnerabilities in IoT technology, is also increasing in proportion to these developments. In this paper, mirror is implemented as an IoT service hub. It can be used in any space where a mirror is installed, and gesture recognition allows control of existing infrared-based devices as well as certain compatible devices. In addition, the system to solve security problems was implemented by applying AES algorithms between all data communications.

Using optically-active 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl (BINAP) as a P-donor, heteroleptic Pt(Ⅱ) compounds (R)-/(S)-(BINAP)Pt(TFBT)2 (H(TFBT) = 2,3,5,6-tetrafluorobenzenethiol) are prepared from (R)-/(S)-(BINAP) and (COD)PtCl2 via (R)-/(S)-(BINAP)PtCl2. These Pt(Ⅱ) compounds are characterized by FT-IR and 1H NMR spectroscopic analyses. It is noted that the arylmonothiolate ligand (TFBT) is labile in solution due to the lack of chelate effect.
