To study the effects of corticosteroids to the bone tissues, author grouped young(3 weeks affter birth) and adult ICR mouse by dosage, injected intramusculaily prednisolone, a series of corticosteroids, to posterior leg during 6 weeks per day, obtained femurs and tibias, measured the lengths of tibias and femurs. The portions of the distal end of tibial crests were cross-sectioned, general H-E stain was perpormed. The adjacent distal portions of femoral neck were sectioned longitudinally, observed endosteal surface by scanning electron micrscope The results were followings: 1. The adult group injected by large dosage (0.56mg/100g body weight/day) and the young group injected by small dosage(0.14mg/100g body weight/day) from 3 weeks after birth were significantly shorter than the normal group according to statistics. And the adult group injected by small dosage (0.14mg/100g body weight/day) was not different from normal group according to statistics. 2. In the light microscopic sutdy, the adult group injected by large dosage decreased in bone mass of compact bone severely, the adult group injected by small dosage changed a little grade. The young group injected by small dosage from 3 weeks after birth was not severe in bone change, but bone thickness decreased. 3. In the scanning elctron microscopic study, the adult group injected by large dosage and the young group iniected by small dosage from 3 weeks after birth decreased in trabeculae. The trabeculae of the adult group injected by small dosage were decreased slightly. 4. Integrating above all, the changes by prednisolone injection osteoporosis, of young period were more severe than those of adult, too.

Mobile MPLS VPN에서의 QoS 지원

송영필,양해권 국립7개대학공동논문집간행위원회 2003 공업기술연구 Vol.3 No.-

The term "VPN", or Virtual Private Network, generally means the public network of vendors which is providing a communication net and other network using WWW as a backbone of its WAN. the existing VPN is expected to reduce expenses and will improve the productivity, however, the network provider should accept the management complexity and the overhead after tunneling and encryption. But MPLS VPN can provide efficient VPN which would not need the address transformation and the additional overhead made by tunneling after giving separately ID. This paper describes the protocol for MPLS VPN which is about a node that moves based on Customer Edge (CE) router and supports a scheme for QoS.

PVC 및 Olefin계 Copolymer의 열안정성에 관한 연구(II) : 열안정 영향 인자 Thermal Stability Factor

송해영,황택성,맹기석,박인환 忠南大學校 産業技術硏究所 1986 산업기술연구논문집 Vol.1 No.2

Several structural factors which governs the thermal stability of poly(vinyl chloride) were investigated by IR and H¹-NMR spectroscopy. PVC-Olefin copolymers having diverse structure were prepared by same reaction conditions such as reaction temperature and comonomer composition. It was found that keto allyl groups in the polymer backbone which were formed through a side reaction show the most pronauncing effect. The content of keto allyl group appeared to increase with the relative amount of olefin comonomers. On the other hand, neither chain branching nor tecticity influenced the thermal stability of copolymer. Also, the content of double bond fromed at chain ends was unrelated to the thermal stability.

In modern societies, there are trends for people to engage in more positive and creative physical activities in their leisure time, which Leads to rather participant sports than spectator sports. This study was undertaken to explore the actual state of " Sports for all" facilities in Korea. The implications of the study are as follows: 1. The total numbers of "Sport for all" facilities in Korea is 20,080 ; there are 328 public facilities, 14,696 school facilities, 1,386 job-site facilities and 3,596 civil vacilitles, which indicates that Korea has got smaller number of those facilitles than the other developed countries. 2. The actual state of the facilities by each citles and counties shows the fact that Seoul has got 2,869 facilities, Incheon 434, facilities and Jeja 290 facilities. 3. The square measure for each Korean People is 0.795㎡. 4. The facilities have been set up in servral particalar events and districts. In conclusion, it is requested that all the facilities should be opened to the publics in order to anltivate the healthy mental and physical condition of peoples and to host various types of competitions, thereby promoting the sports, sport-for-all sports in particular, by means of civil-directed activities.

Polyethylene 필림의 老化防止에 關한 硏究

The tensile and tearing strength of PE film, PE film made from PE regenerated with waste plastics and PE film added with various additives were studied before and after uv radiation. And the experiment results as following. The efficient things for preventing reagent form aging of PE film are DOBP, and phthalocyanine etc. The structure of PE film added with various, reagent, which are compared with those of the commercial PE film were subjected to be determined by Infrared spectrum before and after uv radiation, and the carbonyl group and C-H stretching region were discussed in view of IR spectrum of PE film.

Nowdays, proper merchandising system of clothing is needed not only for functional clothes but also for fashionable ones. Since nineteen eighties, ready­to­wear garments have been popular for Korean women. But it is hard to tell whether or not the system of the ready­to­wear industry is concrete because of the short history. The purpose of this study was to investigate the process of the merchandising system of the ready­to­wear garments and to recognize the problem which the system of the garments had have. Furthermore, it aimed to find out the idea or improving the problem for better ready­to­wear garments. This research was done through information obtained from several libraries. And, the period of this was from May of August, 1984. The results of this study were: 1. There was an indivisible relationship between merchandising system and fashion, and the importance of the merchandising­planning was raised. 2. The manufacturers should research and analyze consumers since they are aiming at them in nature. 3. The manufacturers should aim at the invention of the creative designs and the introduction of advanced techniques in producing textiles and their accessaries. 4. There should be some institutes to teach fashion and other areas related to ready­to­wear garments. 5. It was necessary to inform consumers to be able to select proper garments in the market.

The purpose of this research is in comparing the goods which have been producing in severalcompany and judging them, and examing how much intrested are the consumers in the labels whichgive us informations. In order to certify them we've investigated the degree of confirmation, confidence, utilization andrecognition of the consumers about the labels. The questionnair method was used to obtained the data which was mad by a result of self-adminis-ted questionnair. A size of random sample for this research was 125 subjects. The results are as follows ; 1) Most of the consumers confirm the labels. 2) The degree of the consumers' recognition about the necessity of the labels is nearly correspondwith the utilization of it. 3) The consumers' confidence about the label of ready-made clothes in the open market is relatively low. That's because they(the labels in the open market) are usually incorrect yet and couldn't giveus enough informations.
