영국 국립 박물관 중의 하나인 런던의 월레스 컬렉션은 보존과 관련된 상설 전시를 하고 있는데, 유물의 제작 기법과 재료를 다룬 전시뿐 아니라, 보존에 관한 특별 주제로 전시를 하기도 한다. 월레스 컬렉션의 현재 보존관련 상설전시와 특별 전시 그리고 영국 내 다른 박물관의 예를 통해서, 보존과 일반 대중과의 관계와 교류의 변화를 살펴보고자 한다. 박물관은 기존에는 수동적 정보 전달의 역할이었지만, 현재는 보다 적극적인 교육에 초점을 맞추면서, 보존도 일반 대중의 위한 프로그램과 전시를 통해 이러한 변화에 동참하는 추세다.

Optical property improvements for ONP (old newspaper) and OMG (old magazine) were attempted by application of in-situ $CaCO_3$ formation process on recycled fiber surfaces. Washing treatment of ONP and OMG resulted in 35~40% yield loss for around 6% brightness improvement. Washing plus bleaching process with $H_2O_2$ and FAS (formamidine sulfinic acid) improved brightness and ERIC values a little more with the same amount of yield loss as washing treatment. In-situ $CaCO_3$ formation method improved those optical properties much better than the washing plus bleaching method without loss of yield, and better than the case of adding high brightness PCC up to the same ash level. It can be said that the in-situ $CaCO_3$ formation method may be used as an effective alternative for upgrading optical properties of recycled fibers.

By the experiment of a model Ondol heating system gas flow characteristics in a briquette flue tube was investigated. As a heat source electric heater was used, which renders steady flow condition of air. working fluid. It was observed that the flow augumentation may be obtained by increasing the vertial elevation of the flue tube, namely increase in the tube length or increase in the tube inclination, and the gas temperature at the tube entrance Among several factors which augument the flow rate slope of the flue tube has the most striking effect and then the temperature of gas entering the tube. Increase in length of the tube also auguments the flow but the rate of augumentation is so small that it gives little assistance to improvement of the flow The flow in a briguette flue gas does not essentially satisfy the one dimensional steady flow assumption. It is also observed that the flow begins to accompany irregular velocity fluctuation as inclination of the tube increases.

Two-dimensional jet flows into a couple of confined rectangular enclosures such as an Ondol flue channel and their flow distributions were analyzed by numerical graphics : rectangular space in one enclosure is vacated and the other has 8 rectangular small posts. Both enclosures have a protruded inlet nozzle and on outlet on its center line. Steady state incompressible laminar viscous flow was assumed. The primitive forms of Navier-Stokes equations and continuity equation in a cartesian coordinate system were solved numerically by the Marker and Cell method for Reynolds numbers of 5, 10, 20, 30 and 40. From the numerical graphics it was found that the flow regions in both enclosures were devided into tow parts ; one part was the jet flow localized in a narrow center region of the enclosure and the other part was the very slow recirculating flow occupying the rest of the flow region in the enclosures. However there were a little differences in the shapes of jet flow in both enclosures for Reynolds numbers of 5 and 10 and also in the shapes of recirculating flows in both enclosures for all Reynolds number. Also it was found that waving flow appeared right before the outlet at Reynolds number of 20 and more.

This research was to identify the relationships between sex role attitude and the preference of fashion advertising formatted by sex role expression, and to examine the relationships among sex role attitude and sociographic variables. This research has been done for 618 university students and working group who are living in Cheongju and Seoul. For data analysis, descriptive analysis, ANOVA, and t-test were used. The results are the following: 1. In the view of the preference of fashion advertising, the stereotypical fashion advertising has more point than the androgynous fashion advertising. 2. The advertising formation preference showed a little difference significantly by sex role attitude. The group with conservative sex role preferred the stereotypical fashion advertising. The group with open-minded sex role preferred the androgynous fashion advertising. 3. Women preferred the androgynous advertising. As the aged, they preferred the stereotypical fashion advertising and have the conservative sex role. University students have more intention to buy with an androgynous fashion commercial than working group have and they have the open-minded about sex. The group subscribed the fashion magazine has more preference for androgynous fashion advertising, as they have more open-minded sex role than other group not subscribed the fashion magazine. This results imply that the androgynous formatted advertizing is still hard to get the influence of a general market promotion because most consumers have a low androgynous fashion advertizing preference. The preference of the fashion advertizing which expressed a sex role showed significant differences as social demographics, and a sex-role attitude. Therefore, the market segment and advertising strategies which are based on sex role and consumer characteristics would be very effective.

This study was carried out to develop a method of grain drying ststem that can be done by forcing the heated-air directly into the grains within the sack. The air duct was pushed into the central position of the grain-deposited sack and the heated-air was forced to flow in the radial direction. The system is referred here as the unit sack drying system. At a first step of this study, an air flow resistance tester was constructed to measure the resistance of air flow to grains in cooperated with some different sack materials, the sack materials, the tested were rice-straw bag, sack of polyethylene film, and jute sack In addition, unit sack drying system was constructed to investigate the drying characteristics of the dryer. on this dryer, two kind of terminal air ducts were attached and tested to examine its effects on uniform drying, and also, aseries of drying test was performed to trace the effect of increasing air flow rate on uniform drying. The results are as follows: 1) Resistance of air flow for each sack material was increased almost proportional to the increasing rate of air flow. Experimental data showed little significant differences of the air flow resistance among the materials. 2) From the comparison with air flow resistance of sack material and that of roughrice, it was indicated that airflow resistance of sack material was much higher than that of rice rough Therefore, in the unit sack drying sysle in which air flow is destined to face the sach material after leaving the grain, it was suggested that air flow would be inuniform to each part of grain within sack because of much higher air flow resistance of sack material than that of grain, and the fact would results inuniform grain drying. 3) Drying test on the unit sack drying system in cooperated with different type of terminal air ducts showed that high speed air is better for uniform drying than in high pressure. with the drying system which was assembled with the air ducts delivering higher speed air, there also involved a problem of significant inuniform drying. Therefore, any means to improve the inuniform drying should be undertaken for practical use. 4) A series of drying test with in creasing air flow rate resulted that increasing air flow rate in the unitsack drying system gave little effect on uniform drying, therefore, it is recommened to change its drying system for drying grain uniformly.

중국에서는 21세기에 들어 인간과 자연의 조화 및 생태의 균형 유지가 매우 중시되면서 도시와 농촌간의 경제적 격차를 줄이고 전면적이 협력과 지속적인 발전을 위한 조화로운 사회건설정책을 추진하고 있다. 뿐 아니라 개혁개방 이후 급격한 경제적 변화로 전통 문화의 보존과 중화민족의 역사적 정통성을 유지하기 위하여 문화유산에 대한 애국주의 교육을 더욱 강조하고 있다. 이에 중국은 박물관의 문화유산 보존과 전시기능 뿐 아니라 사회교육의 중요성을 더욱 인식하게 되었으며 새로운 박물관 형태인 생태박물관에 대한 관심을 기울이게 되었다. 중국은 대도시에 집중적으로 건설되었던 대규모의 박물관을 대신하여 노르웨이의 지원과 중국박물관협회를 중심으로 꾸이저우성, 꽝시장족자치구, 내이멍구자치구 등 소수민족이 집중적으로 분포하고 있는 산간 오지지역을 중심으로 생태박물관을 설립하기 시작하였다. 이러한 생태박물관의 건설은 서부대개발이 진행되면서 소수 민족의 고유한 문화에 대한 위기의식에서 비롯되었으며 소수민족에 대한 문화적 수요를 창출하고 경제적 생활향상으로 함께 화해사회(조화로운 사회) 건설에 참여하여야 한다는 인식이 커다랗게 작용하였다. 그러나 중국은 생태박물관 조성을 국가사업으로 전환하면서 민족과 지역 특성에 적합한 형태로 만들고 활성화하기 위하여 소수민족 문화유산에 대한 관리를 더욱 강화하면서 점차 중국화, 본토화하고 있다.

일제 강점기 간행된 "동광" 잡지에 게재된 시조를 분석하여 당대 시조의 특징과 문화현상을 파악하려 했다. 이를 위해 다음과 같은 연구 순서로 진행하였다. "동광"에 게재된 시조의 내용을 중심으로 분석하였는데, (1)임에 대한 정한의 표출 (2)역사 회고 (3)농촌의 정취 (4)사향(思鄕) (5)삶에 대한 성찰과 각오 (6)신의에 대한 성토 (7)이별의 정한 (8)계절 예찬 (9)귀전원과 정감 등으로 대별할 수 있었다. 이중에서도 당대의 특징을 잘 반영하는 주제로 선별하면 대체로 세 가지 정도로 요약할 수 있다. 그 근거는 통계적 기준(작품 수)과 당대 시대상(일제 강점기)을 고려해서 나눈 것이다. 즉 농촌의 정취, 귀전원과 정감, 역사 회고 등이다. 먼저 농촌의 정취를 살펴보면 표면적으로는 평화롭고 정감서린 농촌의 정경을 읊조렸다. 그러나 다른 한편으로는 세금을 내고나면 남는 것이 없는 소작농의 궁핍한 생활을 토로하고 있다. 또 감각적인 표현을 활용하여 농촌 특유의 정감을 유감없이 그려냈다. 다음으로 귀전원과 생활의 정감에 관한 것을 담고 있는데, 전원에서의 정취와 낭만을 노래했다. 즉 1930년대는 전원으로 돌아가는 사회 현상을 시조문학을 통해 살펴 볼 수 있었다. 특히 선경후정(先景後情)의 작법을 활용하여 쉽고 평탄하게 내용을 전개하였으며 이따금 탈속적 정취를 노래했다. 또 도연명의 '채국동리하(採菊東籬下)'의 배경을 활용하고 농촌 정착의 의지를 표출하였다. 마지막으로 역사 회고 시조인데, 현실에 움추린 조선인들을 일깨우기 위해 위국충절과 호연지기를 노래했다. 그리고 여전히 국권회복의 가능성을 갈망하고 있다. 특히 종장에서 밑줄 처리를 통해 고조된 감정을 표출하고 종래에 없던 새로운 시조의 작법을 보여 주기도 했다. 역사 회고 시조는 부당한 현실에 대한 반감을 전제한 것이며, '애달프다'라는 시어는 당대를 바라보는 지식인들의 심정을 압축적으로 대변한 것이다. 1930년 이후는 시조는 이전의 감성적 낭만적인 시조와 달리 논리적이고 사회문제를 전달하려는 스토리를 갖고 있는 것도 있다. 즉 기존의 음악적 요소나 감정에 호소하는 성향보다는 이치적이고 산문적 성향을 갖고 있다. "동광(東光)"의 시조를 통해 당대의 시의성을 반영하고 동시에 우리 문학의 전통성과 정감을 여전히 발산하고 있는 시조의 가치를 확인할 수 있었다.

The main sources of recovered paper for newsprint are old newsprint (ONP) and old magazine (OMG). Recently, a lot of advertisement flyers are flowing into bales of ONP and portion of OMG is increasing in recovered paper because the consumption level of coated paper increases. In this study, nonionic surfactant and fatty acid were used as the de-inking agent for froth-flotation process of mixed recovered paper to investigate the effect of increased mixing ratio of OMG. De-inking efficiency of nonionic surfactant decreased as the mixing ratio of OMG increased; ink removal efficiency of froth-flotation is poor, however, the reject ratio increases due to ash from OMG. In comparison with nonionic surfactant, the ash from OMG had a little effect on reject ratio and optical properties of fatty acid applied flotation accept. If nonionic surfactant and fatty acid are added to pulper and flotation cell sequentially, excessive ash from OMG may not give an adverse effect on de-inking efficiency of mixed recovered paper.

In preparing for the era of Korean reunification, it is essential to consider the integration of medical systems and human resources. While Korean dental practitioners are expanding their activities in various fields both domestically and internationally, there are many restrictions on the activities for improving the health of North Korean people due to political and historical reasons even nowadays. In addition, there is little is known about the current state of dental health in North Korea. We analyzed the reports published by the World Health Organization (WHO) and the Ministry of Public Health of North Korea prepared individually or in cooperation, and investigated the current status of the health care strategy applied to the dental field by conducting a full investigation of the 2018 『Rodong』newspaper. Based on the above, we tried to grasp the major health care strategies in North Korea and their application. Understanding the direction and status of North Korea's health care system would be an important cornerstone for international cooperation and practical activities to improve oral health care of North Koreans in the future. And there is a need that studies should be steadily conducted in various methods to overcome the heterogeneity of the two Koreas in the long-term perspective.
