This experiment was conducted to evaluate the lysine cell mass (LCM) as a dietary fish meal (EM) protein replacer in juvenile Israeli carp, Cyprinus carpio. Fishmeal, a major animal protein source in the control diet, was replaced by tCM on the protein equivalent base, Fish averaging 1,7 $\pm$ 0.1 g (Mean $\pm$ SD) fed one of nine diets containing isonitrogenous and isocaloric basis of $38\%$ crude protein and 15.2 kJ available energy/g diet: control, $100\%$$FM; LCM_20$, $80\%$$FM+20\%$$LCM; LCM_40$, $60\%$$FM+40\%$$LCM; LCM_60$, $40\%$$FM+60\%$$LCM; LCM_100$, $100\%$$LCM; LCM_20$l, $80\%$$FM+20\%$$LCM+0.07\%$$Lysine; LCM_40$l, $60\%$$FM+40\%$$LCM+0.14\%$$Lysine; LCM_60$l $40\%$$FM+60\%$$LCM+0.22\%$ Lysine; LCM_100l, $100\%$ LCM+$0.35\% Lysine. After 6 weeks of feeding trial there was no significant difference in weight gain (WG), feed efficiency (FE), protein efficiency ratio (PER) and specific growth rate (SGR) among fish fed control and $LCM_20$ (P>0.05), while fish fed $LCM_40,\;LCM_60,\;LCM_100,\;LCM_40l,\;LCM_60l\;and\;LCM_100l$ diets had a significantly lower WG, FE, PER and SGR than did fish fed control diet (P<0.05). There was no significant difference in WG, PER and SGR among fish fed control and $LCM_20$l diets (P>0.05), while fish fed $LCM_20$l S had a significantly lower FE than did fish fed control diet (P<0.05). No significant difference was observed in hematocrit and condition facto, among fish fed nine diets (P>0.05). Therefore, these results indicated that LCM could replace FM up to $20\%$ and dietary synthetic lysine supplementation did not show any positive growth effects in juvenile Israeli carp.
Blood supply rather than nerve supply implies pulp vitality. To evaluate pulp vitality clinically, electric pulp test and thermal test which are based on sensory nerve response have been used in addition to many auxiliary data such as past dental history, visual inspection, radiographic examination, percussion, palpation and transillumination test. However, reactivity of the nerves to the stimulation is not synonymous with normalcy. Therefore measurement of pulpal blood flow using a laser Doppler flowmeter became a new trial to test the pulp vitality. The purpose of the present study was to evaluate normal pulpal blood flow level of maxillary teeth in adult to provide a guideline in determining the vitality of dental pulp. Pulpal blood flow was measured in maxillary central and lateral incisors, canines, first and second premolars and first molars of seventy nine adults of 22 - 30 years old using a laser Doppler flowmeter (PeriFlux 4001, Perimed Co., Stockholm, Sweden, 780 nm infrared laser, 1mW). For directly-made splints, silicone rubber impressions were taken directly from the mouth. For indirectly-made splints, alginate impressions were taken from the mouth and stone cast were made. After making depressions on the buccal surfaces of the cast teeth to indicate the hole positions, second impressions with vinyl polysyloxane putty were taken from the cast. Holes for the laser probes were made at the putty impressions 4mm above the gingival level. Laser probe (PF416 dental probe, 1.5mm) was inserted in the prepared hole and the splint was set in the mouth. After 10 minutes of patient relaxing, pulpal blood flow was recorded for 5 minutes on each tooth. The recorded flow was saved in the computer and calculated with a software 'Perisoft' version 5.1. Pulpal blood flow was also recorded in six teeth of five individuals with no response to electric pulp test and cold test, with periapical radiolucency, or with history of root canal treatment to compare with nonvital teeth. The difference between the mean flow values of each group of teeth were analyzed using one-way ANOVA and Duncan's Multiple Range test. The results were as follows: 1. The average pulpal blood flow values of all the tested teeth of each location were between 9 - 16 Perfusion Unit. Pulpal blood flow value was highest in maxillary lateral incisors, followed by first premolars, second premolars, canines, central incisors, and then first molars (p<0.01). 2. In six anterior teeth, indirectly-made splint group showed higher pulpal blood flow values than directly-made splint group (p<0.01). In posterior teeth, however, there was no significant flow value difference between directly-made splint group and indirectly-made splint one (p>0.05). 3. Teeth with vital pulps showed higher signal values than teeth with nonvital pulps (p<0.01), and the flow photographs showed heartbeat-synchronous fluctuations and vasomotions, while those were absent in non vital tooth.

Dietary supplement mainly made of herb and fiber was examined whether it could reduce body weight and fat, modify blood lipid concentrations and bowel habits in 30 collegians without intentional diet restriction or lifestyle change for 5 weeks. Free-living subjects were required to take diet pills 2 times daily 30 minutes before meals. Before the study began, 24 hr recall diet record and the questionnaires had been collected. Anthropometric measurements (height, weight, waist and hip circumferences, triceps and abdomen skinfold thickness, and body fat) were performed and blood samples were withdrawn before and after the study. Blood lipid fractions analyzed were total cholesterol (TC), triglyceride (TG), HDL-cholesterol and LDL-cholesterol. After the trial, body weight, body mass index, and percent ideal body weight of the subjects were reduced to mean of 0.5 kg, 0.2 and $0.9\%$, respectively (p<0.05). Percent body fat, triceps and abdomen skinfold thickness, and waist and hip circumferences were all reduced significantly except for $\%$ abdominal fat, but $\%$ body muscle mass increased from $36.5\%$ to $37.4\%$ (p=0.000). TC and TG were remarkably diminished (p<0.01) and LDL-cholesterol tended to decrease, but no change was observed in HDL-cholesterol. Bowel movements were also increased (p<0.01). In conclusion, this specific herb and fiber-rich dietary supplement reduced body weight and body fat indices, improved anthropometric indices, modified blood lipid fractions and bowel movement desirably. The study suggest that herb and fiber-rich dietary supplement might help control body weight, body fat loss and adult diseases positively.

We performed a randomized placebo-controlled trial to determine whether or not fermented red ginseng supplementation modulates blood glucose and insulin resistance in type 2 diabetic patients. A total of 38 patients were randomized to either a fermented red ginseng group or placebo group. The patients in the experimental or placebo group consumed 780 mg of fermented red ginseng or cellulose supplement per day for 12 weeks, respectively. Lifestyle factors and dietary intakes of the patients were not altered during the 12-weeks period. In the fermented red ginseng group after 12 weeks, the fasting blood glucose levels were significantly decreased ($136.29{\pm}16.45$ mg/dL to $127.71{\pm}17.74$ mg/dL) and $HbA_1c$ was also decreased. Especially, high HbA1c (HbA1c $\geq$8%, $8.45{\pm}0.56%$ to $7.82{\pm}0.53%$) was significantly decreased compared to low HbA1c (HbA1c <8%, $6.71{\pm}0.85%$ to $6.44{\pm}0.49%$) in the fermented red ginseng group. Serum low-density lipoprotein was slightly decreased in the fermented red ginseng group compared to the placebo group. Homeostasis model assessment-insulin resistance was significantly reduced in the fermented red ginseng group compared to the placebo group. These results suggest that fermented red ginseng supplementation could be helpful to reduce blood glucose by improving insulin resistance in type 2 diabetic patients.

It is very important accurate diagnosis and quick treatment in cerebrovascular disease, i.e. stenosis or occlusion that could be caused by risk factors such as poor dietary habits, insufficient exercise, and obesity. Time-of-flight magnetic resonance angiography (TOF-MRA), it is well known as diagnostic method without using contrast agent for cerebrovascular disease, is the most representative and reliable technique. Nevertheless, it still has measurement errors (also known as overestimation) for length of stenosis and area of occlusion in celebral infarction that is built by accumulation and rupture of plaques generated by hemodynamic turbulence. The purpose of this study is to show clinical trial feasibility for 3D-SPACE T2, which is improved by using signal attenuation effects of fluid velocity, in diagnosis of cerebrovascular disease. To model angiostenosis, strictures of different proportions (40%, 50%, 60%, and 70%) and virtual blood stream (normal saline) of different velocities (0.19 ml/sec, 1.5 ml/sec, 2.1 ml/sec, and 2.6 ml/sec) by using dialysis were made. Cross-examinations were performed for 3D-SPACE T2 and TOF-MRA (16 times each). The accuracy of measurement for length of stenosis was compared in all experimental conditions. 3D-SPACE 2T has superiority in terms of accuracy for measurements of the length of stenosis, compared with TOF-MRA. Also, it is robust in fast blood stream and large stenosis than TOF-MRA. 3D-SPACE 2T will be promising technique to increase diagnosis accuracy in narrow complex lesions as like two cerebral small vessels with stenosis, created by hemodynamic turbulence.
Shrimp farming which is entirely conducted in outdoor ponds in the west coast of Korea has been suffered from mass mortality due to viral epizootics. Intensive indoor shrimp culture under limited water exchange can solve these problems of outdoor ponds including viral transmission from environment, pollution due to discharge of rearing water, low productivity and limited culture period. In this study, juvenile L. vannamei (B.W. 0.08-0.09 g) was stocked with $3,000-5,455/m^3$ in density in four raceway tanks (two $12.9\;m^2$, two $18\;m^2$ tanks) and cultured for 42 days with 2.7-3.4% of daily water exchange. Results from four tanks showed FCR of 0.79-1.29, survival of 38.2-48.0%, and yields of $2.49-4.22\;kg/m^3$ which is consistent with 12-20 and 8-14 times higher than those of commercial shrimp hatchery and outdoor pond in Korea, respectively. Concentrations of total ammonia nitrogen in all four tanks were 1.11-1.42 ppm in mean level and did not exceed 6.0 ppm (0.096 ppm of $NH_3$) which is still acceptable levels for shrimp growth. During the culture trial, concentration of $NO_2$-N rapidly increased from stocking, resulting in mean concentration of 18.45-22.07 ppm. It also exceeded 10 ppm over four weeks and maintained at 35-45 ppm for four days in all tanks, accounting for low survival of shrimp due to long-term exposure to high concentration of $NO_2$-N. Nevertheless, the results with survival rate over 38% from raceways which experienced the extreme $NO_2$-N levels suggests that under "biofloc system" white shrimp can acclimate to high $NO_2$-N concentration to some degree.

Objective : The purpose of this research is to find clinical effects of application of weighted vest during task-oriented training focused on gross motor performance and balance abilities of children with spastic diplegia. Methods : 34 subjects were divided by simple random sampling into two groups; experimental group (male : 9, female : 8, average age : 8.12) and placebo group (male : 9, female : 9, average age : 7.53). Both two groups underwent to 40 minute intervention, twice a week for 12 weeks. The intervention was task-oriented training focused on facilitating closed kinematic chain and multi-joint functional movement pattern. During the training, the experimental group received loaded-resistance weighted vest and placebo group also received weighted vest but without loaded-resistance. Participants in both groups underwent 8 to 10 reps of the task-oriented training and there were 3 minutes break time between tasks. There were pre-test of gross motor performance and balance abilities, and two times of post-tests were performed upon 6 weeks and 12 weeks after the intervention completed. And in final, an additional follow-up test was performed 12 weeks after the evaluation was finished in order to find any difference between the two groups over time. Results : There was significant difference in Gross Motor Performance Measure (GMPM) between two groups. It is found that average score of the experimental group increased more than the placebo group after 6 weeks and 12 weeks intervention (p<.05). There was significant difference in Pediatric Berg's Balance Scale (PBS) between two groups. It is found that average score of the experimental group increased more than the placebo group after 6 weeks and 12 weeks intervention (p<.05). Conclusion : Based on the results in this study, it is proposed that application of weighted vest into task-oriented training to facilitating closed kinematic chain and multi-joint movement can improve gross motor performance and balance abilities of children with cerebral palsy.
The development of the aviation technology is beyond the people's imagination. For example, with some exaggeration, If the autopilot engage upon take off, You will realize that you are on the centerline of the foggy JFK runway 13R after 15 hours with only once or twice of intervention. But the more aviation technology develops, the more responsible the pilot will be who has the final authority of the aviation safety. In the JAL 706 accident caused by unidentified reason, the pilot increased pitch abruptly and overrode the control from the autopilot. The result of this process made the death of a flight attendant and some injuries of a few passengers. The district court found the pilot not guilty at the first trial on the ground that the control override was not connected to the possibility of foresight and avoidance of the human death. The pilot was proved to be innocent through the analysis of the DFDR and ADAS that the override did not precede the unidentified pitch up motion. The judicial precedent related to aviation accidents in Korea requires pilots' absolute and extended care compared to the ordinarily prudent or reasonably careful behaviors in the vehicle and medical accidents. Although there is some controversy about the standard care, the care required in the actual operation of high tech aircraft by a pilot should include objective and standard care and be judged by analysis of the scientific data. Although the pilot maintained the unusual hi speed that doesn't have safety margin and descended under turbulence in case of the JAL 706 accident, the court negatived its relation to the cause of pitch up. Also, the override of the control after initial pitch up might have caused the possibility of the death and injury, but the court denied it. Because of this complex cause of the aviation accidents, it is important for a court to figure out the core reason of the event and casual relationship with the pilot Now, It is required that the judgement of negligence in the aviation accidents should include an objective care with scientific data from simulated circumstances(or a simulator) as the Japanese court not from the theory of vehicle's negligence.
Background: The objective responses of cisplatin and etoposide (PVP) combination chemotherapy as second-line therapy following CAV was high (40~50%) and, in several reports, PVP yields survival results that are at least as good as those obtained with cyclophosphamide or doxorubicin-based regimens and with less host-related toxicity in chemotherapy-naive patients. We conducted a phase II study to evaluate the effect of a combination of cisplatin and etoposide as a fitst-line therapy in patients with small cell lung cancer. Methods: Sixty-one previously untreated small cell lung cancer patients with measurable lesion (s) received cisplatin(30 $mg/m^2$ IV, day 1~3) and etoposide(100 $mg/m^2$ IV, day 1~3). In patients with limited disease, after completion of 6 cycles of PVP chemotherapy, chest and prophylatic brain irradiation was performed in case of complete responder, chest irradiation on1y in partial responder. Results: 1) Of 55 evaluable patients, 13(24%) had a complete response and 29(53%) had a partial response. 2) The median survival time was 55.8 weeks for all patients(N=55), 61.1 weeks for limited disease(N=31), 51.3 weeks for extensive disease(N=24). 3) The response duration was 29.1 weeks for responders(N=42). 4) There was no significant prognostic factors influencing response rates. 5) The toxicity was tolerable and there was no treatment-related deaths. Conclusion: The PVP combination chemotherapy as a first-line therapy was effective and well-tolerated in patients with small cell lung cancer.
In order to investigate the difference of rootability between 15 clones of Populus alba${\times}$glandulosa selected based on the growth performance, rooting of cutting experiments with these 15 clones were conducted at the nursery for six years from 1970 to 1975. Cutting experiments in a temperature controlled incubator in which the temperature of the cutting bed were set to $10^{\circ}C$, $15^{\circ}C$, $20^{\circ}C$, $25^{\circ}C$ and $30^{\circ}C$ were also performed. Along with these experiments air layering experiments were performed to compare with the rootabilities obtained from nursery trial. The results obtained so far could be summarized as follows. 1. The best rooting clones were 65-22-4 and 65-22-11, and the average rooting percentages of these two clones for six years were 76.7%, and 72.9% respectively. The poorest rooting clone was 66-6-8 showing average rooting percentage of 45.8%. 2. The middle class of rooting percentage was ocuppied by the clones; 66-14-29, 66-14-93, 66-25-5 and 67-6-3, and the range of their rooting percentage was 60~69% on average. 3. The rooting performances observed through the nursery, the incubator and the air layering experiments were almost the same with exception of few clones. 4. P. alba${\times}$glandulosa showed the best rooting percentage at the cutting bed of $20^{\circ}C$ 5. The most roots, i.e. 78.5% of root per cutting were developed from the bottom part of the cutting shoot. 6. Adventitious and call use roots could observe in the cuttings.
