In this study, an eco-friendly indigo reduction system(scale up reduction, use of buffer solution, and pH control) using baker's yeast(Saccharomyces cerevisiae) was applied for natural indigo(Polygonum tinctorium) dyeing of Hanji fabric and Hanji-mixture fabric(Hanji/Cotton, Hanji/Silk). The effect of concentration of baker's yeast, repeat dyeing, and bath reuse was investigated in terms of dye uptake indicating reduction power. And the oxidation-reduction potential(ORP) was monitored. We also evaluated color properties and colorfastness according to the color strength. The yeast concentration did not significantly affect the maximum reduction power. However, the highest yeast concentration was effective in improving the initial dye uptake, and its the reduction retention power was the most excellent. Even on the last reduction day, the effect of increasing the dye uptake by repeat dyeing was observed. And it was confirmed that the reduction bath could be reused for up to 30 days by supplementing yeast at the end of reduction. For all the fabrics used, deeper and darker PB color were obtained by repeat dyeing. As dyeing was repeated, purplish tint got stronger on the Hanji/Silk fabric compared to other fabrics. Regardless of the composition of Hanji fabrics and color strength, washing and dry cleaning fastness were relatively good with above rating 4-5, and fastness to rubbing and light were acceptable with a rating 3-4 ~ 4-5. The eco-friendly natural indigo dyeing process using niram and baker's yeast would offer global marketability and diversity of Hanji product as a sustainable high value-added material.

비석은 상례문화의 보고이자 서예사의 정수로서 시대사·사회사를 조명할 수 있는 중요한 문화재지만 그 연구는 아직 미미하다. 특히 비각의 제작 방식에 관한 것은 아직 미증유의 분야로 남아 있어 연구가 절실한 편이다. 비석의 제작은 석재의 탁마 과정과 조각, 그리고 글씨를 새기는 북칠 과정으로 대별할 수 있다. 본고에서는 이와 관련하여 몇 가지의 사실을 밝히고 있다. 첫째, 신과 관련한 의물(神儀物)인 상석, 혼유석, 비석에는 정교한 마정(磨正) 작업을 가한다. 이는 임진왜란, 병자호란의 영향으로 인한 유교적 상·제례의 정착과 전파로 혼유석에 대한 인식의 변화에 기인한다. 둘째, 영조 때 오석(烏石)의 비약적인 확산과 사저취용(私儲取用)은 사회·문화사적으로 큰 의미를 가지고 있다. 상품(上品)의 강화석이 고갈되자 사대부에서 사용하던 오석을 천릉한 장릉에 사용한 이후 사대부들을 중심으로 퍼지게 된다. 특히 오석의 사용과 마정 작업은 화학적·물리적 손상을 최소화시킬 수 있었다. 셋째, 비석의 각자 기술은 북칠(北漆)에 있다. 효종 영릉 천릉 시에 송시열의 지문을 북칠한 이후부터 북칠 과정은 동아시아에서 우리나라가 가장 성행했고 제도화된 점은 특기할 만하다. 북칠은 오석의 검은 색으로 인해 흑묵보다 붉은 당주를 이용하면서 더욱 정교화된다. 넷째, 조선 후기에 들어서면서 각자 방식에도 변화가 일어난다. 영조 연간까지 각자는 획의 두께에 따라 각의 깊이를 결정해 음영을 표현하고 양감을 나타냈다. 물론 이 같은 기법은 모든 표석이나 신도비에서 나타나는 것은 아니나 내수사에 소속된 뛰어난 경공장들의 전습에 의해 유지되었다. 따라서 비석을 제작하기 위해서는 숙석, 연정, 마정, 정간, 초도서입, 중초, 입각, 교정, 장황의 단계를 거쳐 하나의 완성품이 이뤄진다. 이러한 것은 묘주에 대한 존경심과 공업을 알리는 목적이지만, 이를 통해 공예 기능의 분업과 협업에 바탕을 둔 작업이 표석의 전체 제작 과정에 나타난다는 사실을 알 수 있다.

Kenaf has a rigid and rough touch that inhibits the use of it as a textile material; therefore, this study developed a novel textile material using kenaf. Kenaf and cotton were blended in the ratio of 3:7 and manufactured as 20' spun yarn that was compared to 20's spun yarn made of 100% cotton. Both kenaf/cotton-blended and 100% cotton spun yarn were constructed as plain woven and knitted fabrics. Four kinds of fabrics were prepared as follows. Plain kenaf/cotton-woven fabrics, plain cotton-woven fabrics, kenaf/cotton jersey, and cotton jersey. A cellulase washing process was carried out to reduce the character of kenaf/cotton-blended fabrics, rigid, and rough touch. All fabrics were pretreated with NaOH. NaOH at the concentrations of 0, 0.25, 1.25, and 2.25mol/L, and cellulase at concentrations of 0, 1, 3 and 5g/L were used since the pretreatment of NaOH has a higher efficiency of weight loss than $Na_2CO_3,\;K2CO_3$ and Triton X-100. The ratio of weight loss, tensile strength, stiffness, drape property, and surface appearance were measured in order to evaluate the efficiency of the washing treatment on fabrics. Kenaf/cotton-blended fabrics exhibited more rigid and rough features than cotton fabrics. A cotton jersey showed significant differences in the degree of stiffness and drape properties. When all fabrics were treated with 1.25mol/L of NaOH and 3g/L of cellulase, kenaf/cotton-blended fabrics showed a higher retention ratio of tensile strength than cotton fabrics after washing despite the increased weight l08s of kenaf-blended fabrics compared to cotton fabrics. The ratio of weight loss for all fabrics was well correlated with flexibility. The washing treatment process made woven fabrics more flexible than knitted fabrics, because the stiffness of woven fabrics made the rubbing actions stronger. Kenaf/cotton-blended fabrics showed a significantly higher ratio of weight loss and more reduction in stiffness than cotton fabrics after the washing treatment. This might be due to the lack of cohesiveness and easy elimination from fabrics. The drape property of kenaf-blended fabrics was superior to cotton fabrics.

The goal of periodontal therapy is the periodontal regeneration by the removal of microorganisms and their toxic products from the periodontally diseased root surface. To achieve periodontal regeneration, root conditioning as an adjunct to root planing has been done. There are low pH etchants such as citric acid, tetracycline-HCl, and EDTA solution which is a neutral chelating agent. The purpose of present study was to examine the effect of root conditioning by citric acid, tetracycline HCl, and EDTA. Total 35 root specimens(6${\times}$3${\times}$2mm) were prepared from the periodontally diseased teeth, scaled and root planed. The specimens were treated with normal saline for 1 minute, saturated citric acid(pH 1) for 3 minutes, 50mg/ml tetracycline-HCl(pH 2) for 5 minutes, 15% EDTA(pH 7) for 5 minutes using rubbing technique. The specimens were examined under scanning electron microscopy at 1000, and 3000 magnification. On the microphotographs taken at 1000 magnification, the numbers of opened and patent dentinal tubules per unit area(10,640${\mu}m^2$) were counted. And the diameters of opened dentinal tubules per unit are (10,640${\mu}m^2$) were measured. The differences of number and diameter among all groups were statistically analyzed by Kruskal Wallis Test. The results were as follows; 1. In the specimens applied with normal saline(control group), the root surface was finely cracked, and was covered by irregular smear layer. Neither exposed dentinal tubules nor any patent dentinal tubules could be seen. 2. In the specimens applied with saturated citric acid(experimental 1 group), the globular collagen fibers were exposed around the peritubular space, and many dentinal tubules were revealed. 3. In the specimens applied with tetracycline-HCl(experimental 2 group), the process-like collagen fibers were exposed around the peritubular space, and some dentinal tubules were revealed. 4. In the specimens applied with 15% EDTA(experimental 3 group), the root surface was covered by the collagenous fibrillar network, and many dentinal tubules were revealed. 5. The numbers of opened and patent dentinal tubules were significantly more in exp. 1 group and exp. 3 group than in exp. 2 group(P<0.05). But there was no significant difference between exp. 1 group and exp. 3 group. In control group, the number of opened and patent dentinal tubules could not be counted because any dentinal tubules couldn't be seen. 6 . The diameter of opened dentinal tubules was significantly smaller in exp. 1 group and exp. 3 group than in exp. 2 group(P<0.05). But there was no significant difference between exp. 1 group and exp. 3 group. In control group, the diameter of opened dentinal tubules could not be measured because any dentinal tubules couldn't be seen. The results demonstrate that root conditioning with citric acid, tetracycline- HCl, and EDTA is more effective in periodontal healing than only root planing, and 15% EDTA solution can replace low pH etching agents such as citric acid, tetracycline-HCl for root conditioning.

1. The number of average milking cows, clinical forms of mastitis, mastitis-developing cows, and cows killed by mastitis a year were 25.7, 1.8(7%), 6.3(26%), and 2.7(10.1%)heads, respectively. The annual grade changes of standard plate counts(SPC) and somatic cell counts(SCC) showed the grade 1A of SPC diminished sharply from April to August, we think it was due to the lack of proper management in farming season and the grade 3 of SCC indirectly influenced increased in huge during August. 2. The average number of parturitions of farms was 2.3, but 50% of below 1 parturition were 22 farms(31%), 50% of above 3 parturitions were 16(23%) out of 71 farms. According to grades of the number of parturitions of milking cows per each farm, the farms' grades recording 3 parturitions and 50% were little bit excellent. 3. The actual situation research of foremilking CMT revealed 35 out of 74 farmer didn't do CMT Among them(35 out of 74 farmers), 80% did not test thanks to the troublesome process of the CMT. SCC grade 3, among farms who did foremilking CMT once or twice a month and who did not were 29% and 40% respectively and SPC grade 1A were 55% and 9%, respectively. 4. The research of actual situation on milking management let us know 29 farms(39%) did not do lastmilking, 37 farms(49%) usually did overmilking, and 34 farms(46%) did milking for 4 or 5 minutes. Grades according to average requiring times of milking showed SCC grade 1 of farms milking within 7 minutes was 11% and SPC grade 1A was 34%, on the other side, farms milking more than 7 minutes were 0% in SCC grade 1 and 13% in SPC grade 1A. Grades according to the starting time of milking after rubbing teats showed SPC grade 1A of farms starting milking at about 1 minute and over 2 minutes were 50% and 20%, respectively. 5. The research of actual situation on hygienic milking management uncovered 65 farms(88%) were using one towel which was used in washing teats and udders to wash more than 3 to 4 cows, and 53 farms(72%) were using one dried towel to dry udders not for each cow but for more than 3 to 4 cows after washing. Also, on milking turns disclosed 30 farms(40%) were milking cows in the order of incoming without isolation of a dominant group. According to grades of towels used in washing teats and udders, farms using a towel for each cow were 56% and a towel for over 3 cows were 31% in SPC grade 1A. According to using-or-not grades of dried towels after washing udders, farms using a towel for each cow were 79% and a towel for over 3 cows were 21% in SPC grade 1A. 6. Farms doing teat-dipping before milking were 7(10%), not doing teat-dipping after milking, or doing sometimes were 9(12%), and doing right after milking were 57(77%). And farms doing teat-dipping after dry cows and before delivery were 21(28a ). Farms using bethadine as an antiseptic solution were 70(95%), 40 farms(59%) diluted it with water as weak as 5 to 10 times, and on drying cows 64 farms(87%) slowly did it more than 2 days. Grade 1A of SPC of farms doing teat-dipping at every milking was 38%, farms doing occasionally or not was 33%, and farms doing it right after milking was 37% and doing after milking more than 5 cows was 20%. Grade 1A of SPC among farms diluting bethadine 5 times and diluting 5 to 10 times with water were 36% and 33%, respectively, and Grade 3 of SCC were 35% and 32%, respectively. 7. Studies on nonlactating period medical treatment, as the cows were on dry, 54 farms treated with their own hands.73 farms(98%) had bovine mastitis treated for themselves. And on applying medicines against mastitis, 55 farmers chose them on the basis of their own experience, 42 farms(57%) were treated more than 3 days. 41 farms(55%) dumped away the mastitis infected milk separately, 24 farms(32%) were feeding and milking at the same time. 8. Fifty-six farms(76%) always washed and disinfected milking machines after milking. Farms using the milking machines at low, or variable vacuum pressures, or at the vacuum pressure, set at the moment of its installation were 31(42%), and farms that did not know pulsation ratio were 27(37%). Farms changing liners when they were torn 8(11%), 58 farms(78%) said they checked milking system when there were wrong with them, 31 farms(42%) changed milking hoses when they found out problems, and 42 farms(57%) cleaned vacuum and milking systems when they felt dirty. The SPC grade 1A of farms washing and sterilizing milking machines was 38% and farms only washing was 28%.

Fully sealed field emission display in size of 4.5 inch has been fabricated using single-wall carbon nanotubes-organic vehicle com-posite. The fabricated display were fully scalable at low temperature below 415$^{\circ}C$ and CNTs were vertically aligned using paste squeeze and surface rubbing techniques. The turn-on fields of 1V/${\mu}{\textrm}{m}$ and field emis-sion current of 1.5mA at 3V/${\mu}{\textrm}{m}$ (J=90${\mu}{\textrm}{m}$/$\textrm{cm}^2$)were observed. Brightness of 1800cd/$m^2$ at 3.7V/${\mu}{\textrm}{m}$ was observed on the entire area of 4.5-inch panel from the green phosphor-ITO glass. The fluctuation of the current was found to be about 7% over a 4.5-inch cath-ode area. This reliable result enables us to produce large area full-color flat panel dis-play in the near future. Carbon nanotubes (CNTs) have attracted much attention because of their unique elec-trical properties and their potential applica-tions [1, 2]. Large aspect ratio of CNTs together with high chemical stability. ther-mal conductivity, and high mechanical strength are advantageous for applications to the field emitter [3]. Several results have been reported on the field emissions from multi-walled nanotubes (MWNTs) and single-walled nanotubes (SWNTs) grown from arc discharge [4, 5]. De Heer et al. have reported the field emission from nan-otubes aligned by the suspension-filtering method. This approach is too difficult to be fully adopted in integration process. Recently, there have been efforts to make applications to field emission devices using nanotubes. Saito et al. demonstrated a car-bon nanotube-based lamp, which was oper-ated at high voltage (10KV) [8]. Aproto-type diode structure was tested by the size of 100mm $\times$ 10mm in vacuum chamber [9]. the difficulties arise from the arrangement of vertically aligned nanotubes after the growth. Recently vertically aligned carbon nanotubes have been synthesized using plasma-enhanced chemical vapor deposition(CVD) [6, 7]. Yet, control of a large area synthesis is still not easily accessible with such approaches. Here we report integra-tion processes of fully sealed 4.5-inch CNT-field emission displays (FEDs). Low turn-on voltage with high brightness, and stabili-ty clearly demonstrate the potential applica-bility of carbon nanotubes to full color dis-plays in near future. For flat panel display in a large area, car-bon nanotubes-based field emitters were fabricated by using nanotubes-organic vehi-cles. The purified SWNTs, which were syn-thesized by dc arc discharge, were dispersed in iso propyl alcohol, and then mixed with on organic binder. The paste of well-dis-persed carbon nanotubes was squeezed onto the metal-patterned sodalime glass throuhg the metal mesh of 20${\mu}{\textrm}{m}$ in size and subse-quently heat-treated in order to remove the organic binder. The insulating spacers in thickness of 200${\mu}{\textrm}{m}$ are inserted between the lower and upper glasses. The Y\ulcornerO\ulcornerS:Eu, ZnS:Cu, Al, and ZnS:Ag, Cl, phosphors are electrically deposited on the upper glass for red, green, and blue colors, respectively. The typical sizes of each phosphor are 2~3 micron. The assembled structure was sealed in an atmosphere of highly purified Ar gas by means of a glass frit. The display plate was evacuated down to the pressure level of 1$\times$10\ulcorner Torr. Three non-evaporable getters of Ti-Zr-V-Fe were activated during the final heat-exhausting procedure. Finally, the active area of 4.5-inch panel with fully sealed carbon nanotubes was pro-duced. Emission currents were character-ized by the DC-mode and pulse-modulating mode at the voltage up to 800 volts. The brightness of field emission was measured by the Luminance calorimeter (BM-7, Topcon).

충주고구려비(忠州高句麗碑)는 발견 이후 탁본(拓本)과 적외선 촬영 등을 통해 판독(判讀)을 시도하였으나 여전히 판독되지 않거나 서로 이견이 있는 글자들이 다수 존재하고 있는 실정이다. 이 연구에서는 반사율변환이미징(RTI)과 3차원 스캐닝 기반의 디지털 가시화 결과를 이용하여 학제 간 디지털 판독을 수행하였다. 이를 근거로 동북아역사재단과 한국고대사학회가 주관하여 작성된 2019년 공동 판독안을 1979년과 2000년의 선행 결과와 정량적으로 비교하여 글자 변화에 따라 8가지 유형으로 분류하고 판독 성과를 고찰하였다. 공동 판독회의 중요한 성과는 기존에 판독되지 않았던 4개의 글자가 새롭게 확정되고, 28개의 글자가 처음으로 제시되었다는 것이다. 또한 선행 판독안에서 이견이 있었던 전면 68자와 좌측면 20자가 합의 과정을 통해 각각 한 글자로 확정되었다. 선행 판독문과 비교하여 '확정'으로 합의된 글자는 총 89자(22.6%)가 증가하였으며, '이견' 글자는 126자(32.0%)가 감소하였다. 이처럼 충주고구려비의 디지털 판독은 RTI와 3차원 스캐닝을 통해 선행 판독문을 재검토하는 데 기여하였다. 그러나 아직까지 확정되지 못한 채 판독이 유보된 상태로 남아 있는 글자들이 123자(31.3%)나 존재하므로 판독률을 높일 수 있는 연구가 꾸준히 필요하다. 향후 충주고구려비를 비롯한 금석문 판독의 고도화는 인문학과 이공학의 융합 연구가 기반이 되어야 하며, 지속적으로 개발되는 영상 분석 기술의 적용뿐만 아니라 글자 신호를 좀 더 가시화할 수 있는 판독 맞춤형 기술 개발에도 노력해야 할 것으로 판단된다.
