The purpose of this survey was to investigate the prevalence of obesity, eating behaviour and life style of college students. This survey was carried out anthropometry and questionnaires in 236 male and 248 female college students in Seoul and Kyongi area. The results are summerized as follows : 1) Average skinfold thickness of the triceps and subscapular in female students were higher than those of male students. Average percentage of body fat in female was higher than that of male. The average BMI, WLI, OR of male were 21.8, 100.6, -1.7, respectively and those of female were 20.4, 99.3, -5.7,respectively. Distribution of BMI, WLI, OR and %BF indicated that BMI was more sensitive for identifying underweight whereas %BF was more sensitive for identifying overweight of female. 2) By BMI, 37% of students belong to underweight groups shereas 7% overweight and obesity ones. The female students showed lower obesity indice than the male. Self-evaluated obesity seemed likely to overestimate their body shapes above BMI, which lead to high unsatisfaction toward their body shape. Males want to gain weight slightly and females want to lose 4.9kg weight. All females want to lose weights. Obese male and females want to lose 12kg, 16kg weights, respectively. 3) Obese group had rapid eating rate, overeating habit, preferences of greasy food and instant food more than any other groups. The preferences of fast food, high caloric density food were lower in obese group than in

The central cholinergic synapse is known to be closely connected with memory. Previously, piracetam has been reported to improve the intellectual ability. We used a scopolamine-induced amnesiac mouse to study the effects of piracetam on memory retrieval by passive avoidance learning test and on the acetylcholine level of cerebral cortex. The amnesia was produced in mouse by the intraperitoneal injection(i.p.) of scopolamine at a dose of 1 ㎎/㎏ body weight(b.w.). Upon administration of piracetam to amnesiac mouse at doses of 100 and 200 ㎎/㎏ b.w., i.p., 30 min, prior to retrieval test, the significant improvement on memory impairment was observed by examination 24 hr after training. The level of acetylcholine in cerebral cortex of mouse was decreased by the scopolamine treatment, however, this decrease was attenuated by piracetam. These results suggest that the effect of piracetam on memory may be attributed to activation of cholinergic nerve.

Assessment of residual stress is an important point to prevent the failures of thin film devices. Nanoindentation technique was proposed as a stress-measuring method of thin film in a previous research. However, the stress-analyzing model used at the previous research had the problems of a partial deformation-irrelative stress interaction concept and no consideration of the change in the contact area during continuous stress relaxation. Therefore, we modified the model by analyzing a new residual stress-induced normal load based on deformation-dependent shear stress component and by calculating the continuous relaxation procedure as an integration method. The modified model was applied to evaluate the residual stresses in two diamond-like carbon films. The evaluated residual stresses from the newly modified model were more consistent with the results from the conventional curvature method than those from the earlier model.

The use of cyclosporine(CsA), a potent immunosuppressive agent, is associated with numerous side effects. Neurotoxicity was earlier less well known, but with growing experience central nervous system side effects are now reported up to 40% of patients. Among various CsA-induced neurotoxicities, tremor is most common and posterior leukoencephalopathy is well characterized. An encephalopathy presenting with pyramidal weakness, however, seems to be rare and poorly documented. We report here a case of encephalopathy presenting with multiple generalized seizures followed by fluctuating quadriparesis developed a few days after starting CsA and resolved spontaneously after withdrawal of the drug . A 48-year-old woman with aplastic anemia was placed upon immmunosuppressive treatment consisting of antithymocyte globulin(ATG), CsA, and methylprednisolone. Two days after starting the therapy, she developed a generalized seizure. The next day she developed 2 more episodes of seizure and the therapy was stopped. Computed tomogram of the brain was normal. Six days after starting therapy, she developed mild motor weakness and paresthesia of both lower extremities, which progressed to a definite quariparesis confining her to a bed in 3 days. Magnetic resonance imaging(MRI) of the brain revealed asymmetric, bilateral high-signal abnormalites in the subcortical white matter of fronto-temporal areas. After reaching to a maximum with some fluactuation(14 days after starting the therapy) the motor weakness started to be resolved. She was discharged with a almost complete resolution of the weakness 45 days after starting the therapy. Five months later she did well and brain MRI was negative.

This study was to investigate the eating behaviors, living habits, food habits, nutrition knowledge, food preference etc. of middle-aged men. This study has been made on the basis of questionnaires to 205 middle-aged men residing in Seoul and Sungnam. The results are as follows: 1. About 48.8% respondents need control of weight. Also, the diagnosed disease of subjects was surveyed. The disease related to irregular food habits and living habits. 2. The average food habits score of total subjects is 5.23 when the posssible maximum score is 10 and their food habits has been considered to be fair. 3. The drinker was investigated to have poor food habits and living habits than the non drinker. 4. The average nutrition knowledge score of respondents was 10.5 and superior to college students, house wives of other study. The correlation between food habits and nutrition knowledge was low. 5. The subjects preferred vegetables, fruits, meats, fish, shellfish, cereals to sugars, oils-fats, milk products. The processed food stuffs and soft drink were not preferred.

Thirteen surface sediment samples collected from the central area of the Yellow Sea, were analyzed for their contents of thirteen metallic elements, including Al, Fe, Ca, Mg, K, Na, Cu, Cr, Ni, Pb, Co, Zn and Mn, as well as their grain-size and organic carbon content. The sandy sediment facies are distributed in the eastern area, the sandy mud and clay sedimentary facies are distributed in the central region, and a patch of fine-grained mud is exists in the western central part. The content of organic carbon which ranges from 0.3 to 1.3% in the sediment showed increase with the decrease of grain-size, and that is dominantly high concentration in the western mud patch region. The total concentration of A1, Fe, Ca, and Mn are higher in the northwestern part near toward the Shandong Peninsula and its decreased the eastern and southeastern part far away from the Huanghe River. This distribution patterns are well coincide with grain-size. The elements content such as Cu, Ni, and Cr are enriches in the southwestern mud patch region and it seems to be partly influence by the Changjiang Diluted Plume.

A transactional approach was used to examine user's responses to living rooms. In experiment 1, 20 subjects evaluated a sample of 28 rooms on nine scale and ranked order the scales as to difficulty of application. A factor analysis yielded three room categories: Decorative, Stylish, and Familiar. Subjects found it easier to make affective rather than cognitive judgments. Experiment 2 examined the effects of relative involvement on responses to the three categories of rooms. 20 graduated students and 25 undergraduate students viewed the 6 rooms(two from each category) and rated each one on six 7-point scales and graduated students only wrote brief imaginative accounts of an episode which might take place in each room. The desire to live in a room was best predicted by perceived beauty and personal involvement. Familiar rooms were preferred most, while decorative rooms were seen as most informative about the person.
