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.

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.

Objectives : We examined the effects of INM 176 (K-l107) compared with placebo on the cognitive functions of 92 old aged subjects with cognitive impairment. Methods : This was a prospective, 12 week, double-blind, Placebo-controlled clinical trial. The elderly who achieved a score of less than 25 points on the K-MMSE or showed a high risk of Alzheimer's disease from the 7-Minute Neurocognitive Screening Battery were considered to have objective impairment and were selected as subjects for this study. The subjects were randomized to placebo or INM 176 group. The outcome measures were from the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog), the Instrumental Activities ofDaily Living (IADL) and the Korean Geriatric Depression Scale (KGDS) and two kinds of computerized priming tests. After setting the total error score in the Alzheimer's Disease Assessment Scale-Cognitive section (ADAS-cog) as the repeated measurement factor, an analysis of variance of the combined factor design was done between the placebo and INM 176 group. Results : The interaction effect of time (pre- and post-trial) and group (placebo and INM 176 group) was significant in the analysis of the ADAS-cog's total error score. The INM 176 group's total error score in the ADAS-cog decreased significantly (p<0.01), whereas the placebo group showed a slight increase. The mean changes in IADL and GDS from baseline scores favored in the INM 176 group than in the placebo group. Outcome changes ofADAS-cog, IADL, KGDS scores during the 12 week clinical trail ofINM 176 and placebo demonstrated favorable responses in the INM176 administered group. Conclusions : This is a preliminary clinical trial result of INM176 as a memory pill. Based on these results, INM176 may be a candidate molecule for the improvement of cognitive functions, including memory, Further clinical trial should demonstrate its efficacy.

Purpose : The purpose of this study was to investigate the dietary habits of students in order to identify risk groups according to their Body Mass Index (BMI), and to compare the eating behavior of students in the normal range (19<I≤24) and those in risk groups (BMI≤19, 24<I≤27, BMI>). Method : 1176 elementary school students, 850 middle school students and 672 high school City, were the participants The instrument for this study was a structured questionnaire that included demographic data as well as dietary habits, and the eating behavior instrument developed by Stunkard &essick(1985) and revised by Kim &im (1997). Result : 1) As students moved up in grade level their dietary habits became more irregular and the degree that students chewed food was reduced 2) As students moved up in grade level, a greater number of the students did not eat breakfast. The reasons given were that there were not enough time before classes started(40.4%) and a lack of appetite in the morning(10.6%) in high school students. 3) As for supper, from 67.8 to 81.9% of subjects reported having regular supper. However the rest of the subjects did not eat supper because of anorexia and fear of weight gain. 4) The results identified risk groups according to their BMI showed that for elementary school students, 55.9% were in the low weight group, 5.5% in the overweight group, and 0.9% in the obese group. For middle and high school students, 40.6% and 35.5% respectively were in the low weight group, 7.4% and 6.3% in the overweight group, and 4.1% and 2.5% the obese group. 5) Comparisons of the eating behavior of students in the normal weight group with that of those in the three risk groups showed that there were significant differences in 'hunger' and 'cognitive restraint of eating' in elementary school students, and significant differences in 'cognitive restraint of eating' in middle and high school students. Conclusion : The results of this study show that management of diet in school health sholud be addressed from both the aspect of lack of nutrition and that of excess nutrition. In other words, good diet is as important for students in the low weight group as it is f3r those in the overweight and obese groups. The estatblishment of good dietary habits and eating behavior in students, by nurses and dieticians should be done by providing repeated diet education and involvement in diet counseling.
