This article is an introduction to : ICCROM PAPERCONSERVATION COURSE 1993" which I participated in, from July 28th 1993 to September 24th. The program was divided into two major sections. The first part deal with scienctific principles of paper conservation, covering structure and composition of paper and related materials, causes of deterioration and guidelines for preservation. It include chemistry for paper conservators and the history and technology of papermaking. Second part of the course emphasize practical conservation ; participants actually work together with specialists. Two weeks are dedicated to the Western approach to paper conservation. A selection of recent conservation treatments are discussed methodologically, demonstrated and performed. The same amount of time are devorted to a seminar on the conservation of fareastern paper objects. The aim is to exporse participants to different approrches and methodologies in paper consevation, to compare and discuss various tendencies and to learn lessons from other experiences that are applicable to one's own work.

We consider the problem of scheduling communications in wireless sensor networks (WSNs) to ensure battery preservation through the use of the sleeping mode of sensors.We propose a communication protocol for 1-hop WSNs and extend it to multi-hop WSNs through the use of a 1-hop clustering algorithm.We propose to schedule communications in each cluster in a virtual communication ring so as to avoid collisions. Since clusters are cliques, only one sensor can speak or listen in a cluster at a time, and all sensors need to speak in each of their clusters at least once to realize the communication protocol. We model this situation as a mathematical program.

This event recorder system, owing to the advancement of communication technology, is independently installed in most on-board electronics and given integrated management by on-board monitoring equipments. However, since the safety oriented equipments such as signalling devices, train protection systems, and train radios have been mounted on trains recently" the existing on-board monitoring device is no longer reliable enough for permanent preservation of data from train crashes or fires. This study has pointed out the problems mentioned above and described the designing concept of the fault recording system for high-speed trains for effective utilization of the train management program.

Environmental matters are one of key issues of today's world. At this point, advanced countries are proposing and planning various kinds of policies for sustainable communities. Space designers in those countries are more concerned with regeneration or slow development than development and innovation. As the new government of Korea was started in 2008, it announced 'design Korea project' as key agenda for national competitiveness. But it seems that they are focusing on development of new town than the concept of preservation or regeneration on which most advanced countries put their bases. In these regards, this research starts with the idea that environmental factor in space design is very important and it is directly connected with human survival. With this idea, the researching team created experimental space titled 'regeneration' as one of eco-friendly education program. The team aimed at building up or 'designing one man space-one to one ratio' in deserted place with recycled stuffs. With the idea of 'regeneration' in space, the researcher aims at awakening the sense of environment and putting it into practice in daily living.

GongJu is a historical city. There has been scattered Baekje, Chosun and modern cultural heritages in GongJu. Cultural heritages in Baekje is simply preserved in their current condition. Chosun and modern cultural heritages have left their traces only, so that faded from the memory of the world. We must not lose the historical interconnectedness that is created by these heritages. This study is to analyze the architectural culture contents and its practical use program in urban side, and search for the strategy. The purpose of this study is as follows: The first is to retrieve the scattered heritages according to the age and area(as a spot). The second is to improve the street landscape through the linear linkage connecting from spot to spot.(as a line) The last is to create the image of historical city through the regional development.(as an area)

Abstraction is the cornerstone of ideal software engineering (SWE). This paper discusses a problem of forming reasonable generalizations, representations and descriptions in various software development processes through the prism of poor-quality (rash, unconsidered, uncertain and harmful) abstractions. To do this, emphasis is made on an induced strategic connection between the required abstraction and its compact specific formulation based on existing research and the author's introspective experience. A software aim point and characteristic preservation of the solution integrity is the subject of the best formulation and a program module or code associated with it. Moreover, a personal attitude expressed by personal interest, motivation and creativity, is proclaimed to be a fundamental factor in successful software development.

School is an excellent place for children to loam environment-conscious behavior and for teachers to bring up environmental education. School has a plenty of teaching materials such as school building, pond, school forest, waste and school supplies. Especially, the environmental education for and with school supplies can be very effective, as it is mostly the first products for children to learn the buying and consumption in their daily life. In this study we conducted a survey on the environmental attitude of two groups of 5th graders towards environmentally friendly school supplies. The experimental group received environmental education on school supplies and the control group did not. The survey results showed that almost 50% of the children did not consider the environmental impact, but rather the price, design and function when buying the school supplies. However, more than 70% of children were willing to use the recycled school products, implying that they are aware of environmental Issues and want to contribute to the preservation and improvement of the environment. The children recognized paper/notebooks and paints/crayons as the major environmental problems. Writing appliances such as pens, pencils, highlighters and markers were also considered as environmental concerns, since most of them are made of plastics and they are not easily biodegradable nor refillable. We also exemplify a lesson-plan for environmental education program on school supplies and make suggestions to encourage the use of those eco-friendly school materials.

In general, collections in museum are kept in storage according to a preservation and administration program in long or short term, after conservators' conservation treatment. Museum activities related to conservation science are common to do before and after exhibitions. That is, the museum collections include a flow mechanism, which circulate a space in where conservation science related activity is carried on centering around its storage. The purpose of this study is to suggest the design guidelines of a conservation area in a museum. The results of this study as follows. First, to program space planning, conservation area of museum is divided into 4 kinds of zone. Second, space for relics unloading in basically includes 'unloading room', 'control room', 'worker room', 'unpacking room', and 'unloading tools storage' and considers to install 'outdoor arrangement space', etc. In case of space for making relics collections, 'arrangement room' and 'temporary storage' are separately planned in order to arrange and temporarily store relics taken in. Conservation analysis space should be divided into 2 kinds of zone, 'conservation analysis lab' for analysis of collection characters and 'restoration lab' for conservation treatment in the bigger museum. In case of large-scale museum, conservation treatment space is basically classified with characters of museum collections. And it considers installing 'waterlogged wood lab', 'painting clothes treatment lab', 'storage of treated relics' etc. Third, for 'the spaces for analysis treatment', must consider activity contents and sizes of the department for scientific conservation every museum, can classify in detail required space, and must review the space for relics settlement in construction.

This treatise focuses on archival service based on social relationship. We hope to seek the possibilities of archival immediate service by this treatise. We cover the 'Youth Archivists Program' of '4.16 memory archives' at this time. This archives has a special meaning in Korea. 'Youth Archivists Program' is an program of archival service in this archives. We suggest archival service based on social relationship by this case study. We have verified that there are some archival services based on social relationship in Korea. We hope that archival service based on social relationship should be an serious issue in Archival community.

Background & Methods: In order to study the effect of electro-lipolysis-acupuncture, 57 outpatients who have had herbal medication in Kirin Oriental Hospital were devided to two groups; acupuncture-treated group(46) vs non-acupuncture-treated group(11) Acupuncture-treated group was given electro-lipolysis-acupuncture at least two times a week and administered with herbal diet medication, whereas non-acupuncture-treated group was administered only with herbal diet medication. Results: Mean age, body weight and BMI of these two group at the start point of the treatment were $27.22({\pm}7.64)\;vs \;29.09({\pm}8.73),\;67.76({\pm}9.34)\;vs\;67.00({\pm}10.69),\;and\;26.20({\pm}3.02)\;vs\;26.14({\pm}4.10)$ in the order of acupuncture-treated and non-acupuncture groups. After one month of treatment, change rate of body weight, BMI, total fat, percentage of fat was significantly higher in acupuncture-treated group. Also the change rate of arm circumference, hip circumference and thigh circumference was significantly higher in acupuncture-treated group. The change rate of abdominal circumference and WHR of acupuncture-treated group was higher than that of non-acupuncture-treated group with no statistical significance. The circumference reduction rate according to herbal dieting program was higher in this order, abdomen, arms, chest, thighs and hips. On the other hand, chest circumference change rate over weight loss rate, which is the portion no acupuncture treatment was given to, and AMC change rate was higher in non-acupuncture-treated group. Conclusion: These results imply that herbal dieting program combined with electro-lipolysis-acupuncture is more effective on reducing body fat, size reduction of localized obesity and preservation of muscle than herbal prescription only dieting program.
