The objective of this study is to investigate the origin of the dolomite in the Pungchon Formation of the Choseon Supergroup near Taebaeg City, Kangwondo, Korea. The Pungchon Formation is composed of limestone, dolomitic limestone, and dolomite with thin beds of flat pebble conglomerate (FPC) and mudrock. Texturally, the dolomite in the Pungchon Formation can be divided into four types; 1) coarse-sized, xenotopic dolomite in massive dolomite, 2) medium-siEed, idiotopic dolomite in flat pebble conglomerate, 3) xenotopic dolomite replacing ooids, algalnodules, and echinoderms, and 4) the dolomite in mottled fabric. The dolomite in mottled fabric can be subdivided into three types; a) coarse-sized, xenotopic saddle dolomite cement, b) medium-sized, idiotopic, cloudy-centered, clear-rimmed (CCCR) dolomite, and c) coarse-sized, idiotopic dolomite. The carbon isotopic composition of the Pungchon dolomite is in the range of $-2.8-1.4\%_{\circ}(PBD)$, suggesting that the carbon isotopic composition was buffered by the preexisting marine carbonates. Lighter oxygen isotopic values ($\delta^{18}O-15.7-8.7\%_{\circ}, PBD$) indicate that the Pungchon dolomite may have formed under high temperature in a burial diagenetic environment. The higher initial $^{87}Sr/^{86}Sr$ ratio of the Pungchon dolomite (0.7010-0.7161) than that of the coeval Cambrian seawater (0.7088-0.7092) indicates that dolomitizing fluids had been modified from the isotopic exchange with continental crust. Low Sr and Na contents(<200 ppm) of dolomite agree well with previously reported data for burial dolomite. Hifh Fe and Mn contents of the dolomite support the idea that the Pungchon dolomite may have formed in a deep burial diagenetic environment.

This study intended to propose a guideline designed to secure safety by developing a functional color design for the color of the ordinary working clothes worn in the actual industrial settings of the machine industry in national industrial complexes in Korea. For this, a total of 6 sets of actual working clothes were produced for test, using 2-color arrangements with blue, of varying brightness and chroma for top and bottom, in relation to the visibility proven in preceding studies and evaluated in the machine industry. Blue was suggested the best proper color for machine industry by previous studies. For the material of working clothes, a total of 111 swatches were collected from the Dongdaemoon Fabric Market, and they were analyzed for color values. A total of 6 materials were used to produce working clothes for testing, which represented high brightness, medium brightness, low brightness, high chroma, medium chroma, and low chroma. Clothes were tried at the industrial settings for machine industry in a national industrial complex located in Gyeongsangnam-do and the expert satisfaction evaluation was performed based on items related with safety. As a result, higher satisfaction was shown when the brightness difference of top and bottom clothes was greater, and for chroma, relatively higher satisfaction appeared when the chroma of both top and bottom clothes was high. To secure satisfaction for both brightness and chroma, it is possible to deduce that the 2-color arrangement using the strong tone with high brightness and high chroma and the dark tone with somewhat low brightness and high chroma would be effective. Top and bottom clothes in the same color with high chroma had high visibility but had somewhat low evaluation for harmonious arrangements. This indicated that the arrangement of vivid colors for top-bottom clothes is inappropriate.

최근, 수송기기 분야는 국제 환경규제 강화에 따른 CO2 절감, 연비향상, 경량화를 위한 기술적 수요가 증대되고 있으며, 그린카, 그린선박 등 친환경 수송기기에 대한 연구가 활발히 진행되고 있다. 하지만, 기존의 금속소재가 가지는 경량화의 한계를 극복하기 위해서는 CFRP, GFRP 등 금속대체 복합소재를 적용한 수송용 경량부품 개발에 대한 필요성이 요구되고 있다. 복합소재는 섬유사이에서 응력을 전달하는 기지(Matrix)와 하중을 전달하는 섬유(Fiber)의 종류와 양 및 적층 각도에 따라 수송용 부품에 적합한 기계적 특성을 얻을 수 있고, 높은 비강도와 비강성의 값을 갖게 되어 경량화가 용이한 장점이 있다. 반면, 섬유재의 종류, 성형방법, 경화온도 등에 따라 물리적 특성에 큰 변화가 발생하며, 수지의 경화조건에 따라 성형시간이 많이 소요되는 단점을 가지고 있다. 따라서, 본 연구에서는 자동차, 선박, 항공기, 철도차량 등 각종 수송기기의 경량화를 목적으로 생산성 향상 및 성형시간 절감을 위해 열가소성 수지, 저온속경화 수지를 적용하여, 경화 시간을 단축시키고, 3D-fabric 및 다층구조 직물을 Vacuum Infusion 공법으로 성형하여, 기존의 섬유재 적층시 소요되는 작업 공정을 간소화 할 수 있도록, 고속성형 복합소재를 적용한 수송용 경량부품 개발에 관한 연구를 수행하였다.

e-Governance is a medium to offer various services to citizens through a web portal, that exists in many countries nowadays. The existing e-Governance technology is a vast, centrally managed database and a set of applications that connect to it via web interfaces. Despite the modernisation of services, it remains with the lack of transparency. Thus, the existing infrastructure of e-Governance paves the way for corrupt practises by the bureaucrats. e-Governance needs a powerful underlying technology which doesn't provide any way to allow tampering of the record and which in turn eliminates corruption. In this paper, we took land registration as a use-case for building e-Governance by keeping Blockchain as an underlying technology, to put off the corrupt practices and to bring transparency. Once transactions in land registration added to the Blockchain, it is immutable as it is cryptographically secured. Besides, the blockchain technology is secured as the ledger is distributed over the network. If a hacker wants to modify the ledger, he needs to hack every node in the blockchain network. Hyperledger Fabric, a permissioned Blockchain adopted for implementation and Hyperledger Caliper for performance analysis with these evaluation metrics such as throughput, latency and execution time.

The aim of the present study was to measure intra-individual consistency in clothing and fabric evaluation and to examine its relation to the ratings. A sample of 93 female and 97 male university students rated clothing of 4 styles of daytime wear and 2 fabrics on 15 pairs of polar adjectives twice in 7-days interval. Correlation coefficients between the two ratings for each subject, intra-individual consistency in the evaluation, ranged from -0.12 to 0.89 and mean coefficient was 0.63 of female and -0.01 to 0.78 and mean coefficient was 0.54 of male. Based on the coefficients, the subjects were classified into three groups: high, medium, and low intra-individual consistency. Analysis of variance of mean ratings by the three groups revealed that significant difference existed in 24% of female and 23% of male in 90 combinations of 6 clothing and 15 semantic differential scales. Female of subjects with high intra-individual consistency were most likely definite to evaluate clothing, whereas the ones with low were least. But male subjects were not definite. Mean correlation coefficients for style evaluation subscales of female was 0.39, but male was 0.44. Among the semantic differential scales, high stability in the two ratings was observed for the synthetic clothing evaluation. Correlation coefficients for each clothing obtained from the mean score of the subjects in each semantics differential scale were around 0.98, including that the mean scores of the subjects in each scale could yield excellent stability in clothing evaluation.

Tencel fabrics were treated with NaOH, mechanically prefibrillated, and hydrolyzed by cellulase. Softner was applied to improve hand of the treated Tencel fabrics after prefibrillation and cellulase treatment. Kawabata's Evaluation System for Fabrics(KES-FB) was used to evaluate effects of NaOH pretreatment, prebifrillation, and cellulase and softner treatments on fabric hand of the treated fabrics. Primary hand values of women's medium thick fabrics such as KOSHI, NUMERI, FUKURAMI, and SOFUTOSA, and total hand values were evaluation parameters. As the treatments of prefibrillation, cellulase, and softner progressed, values in bending and shearing properties decreased and softness and elasticity were imparted to the treated fabrics. Specifically, compressional linearity, compressional energy, and thickness of the treated fabrics increased by prefibrillation, providing bulkiness to the treated fabrics. Values indicating surface properties increased owing to fibrils formed by prefibrillation treatment, but removal of fibrils by cellulase treatment enhanced smoothness. As the fabrics were exposed to various treatments such as NaOH pretreatments, prefibrillation, and cellulase and softner treatments, NUMERI, FUKURAMI, SOFUTOSA, and total hand values increased with the exception of KOSHI, Consequently, the treated fabrics became softer, smoother, and more elastic. Especially, the NaOH pretreatment provided superior SOFUTOSA to Tencel fabrics.

The aim of this study is to develope eco-printing method using natural pigments and chitosan as a natural binder. Three chitosans with different molecular weights were employed to find appropriate conditions including chitosan concentration and pigment/binder ratio. Dye uptake, color and fastnesses of the printed fabrics were evaluated to find optimum conditions within the range of experiments carried out in this study. The effectiveness of chitosan as a printing binder was examined in comparison with color, dye uptake, and fastnesses of conventional synthetic binder and guar gum. It was found that chitosans with low or medium molecular weight were appropriate. Using low molecular weight chitosan, optimum concentrations were 1.7% for charcoal, madder and chlorophyll, whereas 2.2% for ocher, yellow soil, indigo and cochineal. Regardless of molecular weight and concentration of chitosan, the color fastnesess of fabrics printed with mineral pigments were superior to those of the fabrics printed with plant and animal pigments. As pigment/chitosan ratio became higher, rubbing fastness was decreased by 1-3 grade. The colorfastness of printed fabric with chitosan binder was similar to that with synthetic binder, which was higher than that with guar gum.
