The cement industry brought very severe environment problems with massive carbon dioxide during its production. To solve this problem, attempts on Alkali-Activated Slag (AAS) concrete that perfectly substitutes industrial by-products such as ground granulated blast furnace slag (GGBFS) for cement are being actively made. AAS concrete is possible to have high strength development at room temperature, however, it is difficult to ensure the working time due to the fast setting time and the loss of workabillity because of the alkali reaction. In this study, the early age properties of alkali activated slag mortar are investigated to obtain the fundamental data for AAS concrete application to structural members. The water-binder ratio (W/B) was fixed at 0.35 and sodium hydroxide and waterglass as alkali activator was used. The compressive strength, the flow and the ultrasonic pulse velocity were measured according to the type of superplasticisers, which were naphthalene(N), lignin(L), melamine(M) and PC(P), up to a maximum of 2 percent by the mass of GGBFS. The results showed that adding melamine type of superplasticizer improved the fluidity of AAS mortar without decreasing the compressive strength, while naphthalene and polycarbonate type of superplasticizer had little effect on the fluidity of AAS mortar.

Thirty-six weaned piglets with an initial body weight (BW) of 8.43 ± 0.40 kg (28 days of age, ([Landrace × Yorkshire] × Duroc) were randomly assigned to 6 treatments for a 2-week feeding trial to determine the effects of different inorganic zinc (IZ), organic zinc (OZ) or combination of low crude protein diet (LP) and Mixed feed additive (MFA) on diarrhea score, nutrient digestibility, zinc utilization, blood profiles, organ weight, and fecal microflora in weaned piglet diet. The pigs were individually placed in 45 × 55 × 45 cm stainless steel metabolism cages in an environmentally controlled room (30 ± 1℃). The dietary treatments included a negative control (NC), positive control (PC; zinc oxide, 1,000 mg/kg), T1 (IZ : OZ, 850 : 150), T2 (IZ : OZ 700 : 300), T3 (IZ : OZ, 500 : 500), and T4 (LP + MFA [0.1% Essential oils + 0.08% Protease + 0.02% Xylanase]). The daily feed allowance was adjusted to 2.7 times the maintenance requirement for digestible energy (2.7 × 110 kcal of DE/kg BW0.75). This allowance was divided into two equal parts, and the piglets were fed at 08 : 30 and 17 : 30 each day. Water was provided ad libitum through a drinking nipple. The diarrhea score was significantly increased (p < 0.05) in NC treatment compared with other treatments. The apparent total tract digestibility (ATTD) of dry matter (DM), nitrogen (N), and gross energy (GE) was significantly increased (p < 0.05) in the T2 treatment compared with the PC and NC treatments in week 1. In week 2, the ATTD of DM, N, and GE was significantly decreased (p < 0.05) in the NC treatment compared with other treatments. The T3 treatment had significantly higher (p < 0.05) ATTD and apparent ileal digestibility of zinc than the PC and T1 treatments. The Escherichia coli count in feces was significantly decreased in the T4 treatment compared with the NC and T2 treatments. The Lactobacillus count in feces was significantly increased in the T4 and T1 treatment compared with the T2 and T3 treatments. In conclusion, IZ : OZ 500 : 500 levels could improve nutrient digestibility and zinc utilization in weaned piglets, Moreover, MFA in LP diets could be used as a zinc alternative.

This study was attempted to prove the effect of emotional stability and vital signs applying music therapy program to the children admitted in the PICU. Data were collected from July to September, 1997. The subjects were 30 patients admitted in the PICU of 'S' University Hospital which were divided into two groups of experimental and control. Each group had 15 subjects. Method was nonequivalent control group pretest-postteset repeated design, observing vital signs and activity of subjects prior, during, and after the music intervention. The study tools were cassette tapes of 'Mother's music whose babies want to listen' and Space-lab patient monitor. Data were analyzed using the $SPSS/PC+;x^2$ test and t-test to analyze of the general characteristics ; paired t-test to prove hypotheses. Result were as follows; 1. Infants lower than seven months showed changing into stable vital signs from applying the music therapy, however infants from eight months to three-year old showed no change in vital signs. 2. Vital signs changed to stabilized condition in infants lower than seven months were heart rate and respiration rate. 3. The stability of vital signs during music therapy turned back to the previous state while terminating music therapy. 4. The effect of music therapy in the state of activity had on both infants group of lower than seven months and from eight months to three-year old, particularly more effective in the later group. I recommend follows on the base of above results ; 1. As above results shows, listening to music is effective on infants and toddler, intervention with music therapy appropriate to chidlren's age is hot recommended. 2. Comparative study with noise blocking effect and music therapy effect within the ICU environment be recommended. 3. The repeated study on when the exact time is and how many repeat the music therapy to show the above mentioned effect be recommended. 4. We recommend this music therapy to be done in the recovery room, isolating room, operating room as well as ICU.

In actuality, as most of harmful businesses running at school environment hygiene purification zones are stationeries with game rooms, comic book stores, PC rooms, etc., which are highly accessible to students, they become serious problems in school environment. The present study conducted a survey of violation cases at school environment sanitation and purification zones around 21 elementary schools in Seoul. The objectives of this study are, first, to investigate harmful environment around schools regulated by the School Health Act, and second, to suggest plans to improve harmful environment around schools. According to the results of our survey, illegal acts and facilities observed at school environment sanitation and purification zones are as follows. Amusement pubs/room saloons occupied 52.5%, singing rooms 15.4%, game rooms 15.1%, billiard clubs 4.3%, gambling houses 4.3%, hotels/motels/inns 3.6%, cartoon shops 2.6%, video rooms 1.0%, LPG storages 0.7%, and infectious disease hospitals/detention hospitals/detention facilities 0.7%. As it is required to make continuous and systematic surveys and researches on the environmental hygiene around schools, we need to manage school environment efficiently through cooperation among the government, education offices and individual schools.
As a digital TV has outstanding features of being the most influential device in the living room and having the wide spectrum of users, several internet services has been ported on the digital TV platform (in the form of data services) in order to enhance their brand powers. Most of the services, however, failed to get a satisfactory results as the data services are defeated by the broadcasting contents in the competition for the viewer's interests. In the paper, the design guidelines that make data services not to compete with the broadcasting contents are proposed and a prototype of a data service that accommodates the guidelines is introduced.

An efficient laparoscope manipulator robot was designed to automatically control the position of laparoscope via a passive joint on end-effector position. The end position of the manipulator is controlled to have corresponding velocity defined in the global coordinate space using laparoscopic visual information. Desired spatial position of laparoscope was derived from detected positions of surgical instrument tips, then the clinical viewing plane was moved by visual servoing task. The laparoscope manipulator is advantageous for automatically maintaining clinically important views in the laparoscopic image without any additional operator. A laparoscope is mounted to a holder which is linked to four degree of freedom manipulator via universal joint-type passive rings connection. No change in the design of laparoscope or manipulator is necessary for its application to surgery assistant robot system. Expanded working space and surgical efficiency were accomplished by implementing slant linking structure between laparoscope and manipulator. To ensure reliable positioning accuracy and controllability, the motion of laparoscope in an abdominal space through trocar was inspected using geometrical analysis. A designed laparoscope manipulating robot system can be easily set up and controlled in an operation room since it has a few subsidiary devices such as a laparoscope light source regulator, a control PC, and a power supply.
Housing consumers prefer high-rise mixed-use apartments because of one-stop living style, and high quality of life. This study investigated the residents community with the residents who lived in the apartments and the future residents who will live in the apartments to investigate the usage of the public spaces and the influence of the space to form housing culture of residents family community. All data were taken from the response of two hundred forty three questionnaire to be gathered during 20th of June through 24th of August in 2003. Data were analyzed with percentages, means, t-test, and variance analysis using SPSS/PC+. Residents in four high-rise mixed-use apartments feels that the public space in the apartments were mainly provided by their convenience of the construction companies not for the residents. Physical conditions of public space in high-rise mixed-use apartments should be environmentally friendly housing space in which nature and human can be coexisted. It also should be high-tech system housing with which SOHO can be operated. And different custom-made spaces which the residents' needs can be satisfying should be provided. The public space should be recommended to be multi-purposed room because the space will be differentiated with the circumstances of the area, the residents' age differences, and the variety of the family's life style. Moreover, the various programs should be supplied to run the public space efficiently.

Creep characteristic is an important failure mechanism when evaluating engineering materials that are soft material as polymers or used as mechanical elements at high temperatures. One of the popular thermo-plastic polymers, Acrylonitrile Butadiene Styrene (ABS) which is used broadly for machine elements material, as it has excellent mechanical properties such as impact resistance, toughness and stiffness compared to other polymers, was studied for creep characteristic at different levels of stress and temperatures. From the experimental results, the creep limit of ABS at room temperature is 80 % of tensile strength which is higher than PE and lower than PC or PMMA. Also the creep limits decreased to linearly as the temperatures increased, up to $80^{\circ}C$ which is the softening temperature of Butadiene ($82^{\circ}C$). Also the secondary stage of creep among the three creep stages for different levels of stress and temperature was non-existent which occurred for many metals by strain hardening effect.
