We investigated the oviposition characteristics of Protaetia brevitarsis seulensis, focusing on zone breeding throughout the year in terms of the development and utilization of insect resources. To select Protaetia brevitarsis seulensis individuals laying a large number of eggs, the number of eggs laid for each individual was measured for each individual after emergence as adults from larvae grown at room temperature in five farmhouses. The five study zone included Gongju (Tancheon), Gyeonggi (Himsen), Chungnam (Gyeryong), Taean (Wonbuk), and Siheung (Baekse). The average oviposition tendency during a 12-week period obtained from the five regions was somewhat different; however, there was no remarkable difference in overall tendency. The maximum oviposition in Protaetia brevitarsisseulensis in the five regions occurred between 6 and 7 weeks. Compared toother regions, the average cumulative number of eggs laid during the 12-week period was higher (40%-60%) in Gongju (Tancheon) and Gyeonggi (Himsen). These results indicate that in two regions, zone breeding is selected as a system for increasing the demand for insects.

Purpose: The purpose of this study was to compare the change in pain, Neck Disability Index score, and the craniovertebral angle by performing scapular correction exercise or general neck exercise for five weeks in participants with mechanical neck pain. Methods: A total of 31 participants were randomly assigned between the scapular correction exercise and the general neck exercise groups, and all participants performed intervention for 40 minutes each, three times a week for five weeks The effects were evaluated by measuring the Visual Analog Scale score, the Neck Disability Index score, and the craniovertebral angle, before and after the intervention. Independent t-tests were used to compare differences between two groups, and to compare differences between pre- and post-intervention, paired t-tests were used. Results: As measured before and after the intervention, the scapular correction exercise group showed significant improvement in all variables (p<0.05), while the general neck exercise group improved only in the neck disability index score. The differences between the two groups revealed further improvement in the scapular correction exercise group compared to the general neck exercise group (p<0.05). Conclusion: We found that five weeks of the scapular correction exercise to modify the position and movements of the scapula is clinically an important treatment tool for recovery from chronic mechanical neck pain symptoms and restoration of proper neck function.

This study was designed to clarify the morphometrical change of lymph node, deep cortex and lymph follicles in draining lymph nodes of young mice in response to local injection of lipopolysaccharide(LPS). 1. In the group stimulated with LPS, aged 0 day and 3 days, the number of lymph follicles were not significantly different from those of control group. 2. In the group two to four weeks after injection with LPS, aged five days and one week, the number of lymph follicles were significantly increased from those of control group. 3. In the group one to four weeks after injection with LPS, aged 0 day, three days, five days and one week, the area of lymph node and deep cortex increased about 1.5-3 times more than that of the control group. 4. In the group two to four weeks after injection with LPS, aged three days, five days and one week, the lymph follicles(the area: larger than 0.1 mm2) were increased from those of control group. 5. In the group two to four weeks after injection with LPS, aged five days and one week, the lymph follicles(the area: smaller than 0.01 mm2) were increased from those of control group. In view of these experimental findings, the formation of lymph follicles were induced by LPS stimulation from 5 days to one week after birth. The newley formed lymph follicles area in response to LPS may be less than $0.01mm^2$.

In order to evaluate the effect of lipids on the utilization of the energy and protein of the diet, the isocaloric and isoprotein diets added with mutton fat, tallow, and lecithin at the levels of two percent and five percent were prepared. The growth of chicken and the feed efficiency were observed on hatched chicken which were fed a commercial diet for the first week, with starters for the next four weeks, and with finisher diets for the last three weeks respectively during the eight weeks of the experiment. Growth rate, feed efficiency, and average body weight gain per day were similar among the chicken fed diets containing various lipids or at the levels of two percent and five percent. The metabolize energy of the diets was found to be from 2.713 kcal to 3.059 kcal per gram, and the metabolizability of the gross energy was from 62 percent to 70 percent. Also the metabolizability of basal diet was higher as compared with the diets containing lipids. And the lower energy utiliztion was found in the broilers fed diets containing five percent lipids than those of two percent, showing not significant difference between them. Daily matabolizable energy of three week old brids ranged from 0.631 gr to 0.738 gr, which showed an increasing tendency on the birds fed five percent mutton fat and tallow in comparison with those of two percent. But the lecithin brought about a reverse tendency. The digestibility of crude fats was found to be from 48 percent to 76 percent, but bot significant difference among diets plus lipids or at the levels of two percent and five percent. The birds fed five percent mutton fat and tallow showed a tendency of lower digestibility as compared with those fed two percent, but the similar results were found between two percent and five percent lecithin fed to the birds. Then, it was tentatively concluded that the effect of the mutton fat on the energy and protein utilization was similar to tallow but resulted different tendency with lecithin.

Objectives: To determine the optimal timing for post space preparation of root canals sealed with epoxy resin-based AH Plus sealer in terms of its polymerization and influence on apical leakage. Materials and Methods: The epoxy polymerization of AH Plus (Dentsply DeTrey) as a function of time after mixing (8, 24, and 72 hours, and 1 week) was evaluated using Fourier transform infrared (FTIR) spectroscopy and microhardness measurements. The change in the glass transition temperature ($T_g$) of the material with time was also investigated using differential scanning calorimetry (DSC). Fifty extracted human single-rooted premolars were filled with gutta-percha and AH Plus, and randomly separated into five groups (n = 10) based on post space preparation timing (immediately after root canal obturation and 8, 24, and 72 hours, and 1 week after root canal obturation). The extent of apical leakage (mm) of the five groups was compared using a dye leakage test. Each dataset was statistically analyzed by one-way analysis of variance and Tukey's post hoc test (${\alpha}=0.05$). Results: Continuous epoxy polymerization of the material with time was observed. Although the $T_g$ values of the material gradually increased with time, the specimens presented no clear $T_g$ value at 1 week after mixing. When the post space was prepared 1 week after root canal obturation, the leakage was significantly higher than in the other groups (p < 0.05), among which there was no significant difference in leakage. Conclusions: Poor apical seal was detected when post space preparation was delayed until 1 week after root canal obturation.

The present study was investigated the oviposition characteristics of Protaetia brevitarsis seulensis with a focus on winter larvae to improve the utilization of insect resources. The average oviposition tendency and average cumulative number of eggs laid during a 7-week period were measured in adults emerging from larvae that had hibernated for 4 months in five farmhouses. The study covered five zones: Gimje, Jangsu, Wanju, Iksan and Yeoju. The average oviposition tendency over a 7-week period showed increased egg laying between 2 to 3 weeks and 5 to 6 weeks. Overall, it was found that the average cumulative number of eggs laid during the 7-week period was initially low and increased proportionally with time. Our results suggest that using adults that have emerged from hibernated larvae is effective in increasing the oviposition rate and utilization of the insect.

Objectives : Terminal stage cancer patient from primary hepatocellular carcinoma metastasized into lungs was administered with cultivated wild ginseng herbal acupuncture for 5 months and observed progression. Methods : Cultivated wild ginseng herbal acupuncture was administered 5 times a week at about 150cc dosage per week. Dynamic CT was taken and interpreted at a university hospital. Results : Above patient was diagnosed with hepatocellular carcinoma and received one procedure of lobectomy and three procedures of TACE, but because of metastasis, chance of improvement was very obscure. Intensive treatment of cultivated wild ginseng herbal acupuncture five times a week for five months in association with moxibustion was done on the patient. Near elimination of the cancer cells metastasized into lungs were confirmed in terms of radiological impression through dynamic CT. Conclusion: From the results obtained in this study, cultivated wild ginseng herbal acupuncture can be an effective measure against terminal stage cancer. But this is a single case study and lack of extensive follow-up must be compensated by further researches.

Enzyme-linked immunosorbent assay(ELISA) using crude and affinity-purified antigens of adult worms of Paragonimus westermani was performed for infected cat sera with different worm burden, from preinfection to 18th week after infection. Crude antigen was used with supernatant of homogenated worms by freezing-thawing method, and the supernate was centrifuged for 1 hour at 10,000 rpm at $4^{\circ}C$. Affinity-purified antigen(antibody-bound antigen) was prepared from fractions(bound and unbound) of crude antigen by affinity chromatography on CNBr-activated sepharose 4B, and IgG as a ligand was prepared from paragonimiasis cat serum(6 months infected) obtained by ammonium sulfate ($40%{\sim}45%$ saturated) precipitation method. By SDS-PAGE, crude antigen showed 22 polypeptide fractions while purified antigen showed 4 fractions: 36, 400, 34, 700, 27, 600 and 11, 500 in molecular weights. All cats were divided into five groups($G_1-G_5$) by different worm burdens. The mean of recovered worms(${\pm}SD$) and the number of cats in each group are as follows: $G_1$, 2 worms(0) and 4 cats; $G_2$, 4.75 (${\pm}0.66$) and eight; $G_3$, 10.75(${\pm}1.92$) and four; $G_4$, 23.20(${\pm}3.43$) and five; $G_5$, 48(${\pm}12.63$) and five cats. The results were summarized as follows: 1. The antibody levels(OD value) increased by worm burden in $G_1$ to $G_4$ generally. However, individual antibody levels were not exactly related with worm burden in all groups, especially there was a wide difference in $G_4$ and $G_5$. These results suggested that the worm burden in $G_4$ (about $20{\sim}30$ worms) is enough to produce antibody maximum in cats of $2{\sim}3kg$ weight. 2. The antibody levels increased significantly(p<0.05) compared to control sera at the 3rd week in $G_1$ and $G_2$, at the 2nd week in $G_3$, and at the 1st week in $G_4$ and $G_5$. Especially in the 4th week, OD value increased more in $G_1$(p<0.01) and in $G_2$ to $G_5$(p<0.001). In the pattern of antibody levels by ELISA in each group, OD in $G_1$ increased to the 18th week continuously, in $G_2$ OD was maintained same after the 16th week, but in $G_3$ it decreased after the 16th week, and it was maintained same in $G_4$ and $G_5$ after the 14th week. 3. The antibody levels by ELISA with the affinity-purified antigen were higher than those with crude antigen in all groups generally. Especially, the difference of OD values between two antigens was larger from the 4th to the 10th week. In $G_1$ and $G_2$ OD with purified antigen was higher than that with crude one to the 18th week. It was also higher in $G_3$ than that with crude antigen to the 16th week and OD of $G_4$ and $G_5$ were higher before the 14th week than that with crude antigen, however became lower at the 16th week. Consequently, the antibody level in ELISA with affinity-purified antigen was more sensitive at the early weeks after infection and in light infection groups than that with crude antigen.

Purpose : The purpose of this study was to examine the effects of short neck flexor strengthening in proprioceptive neuromuscular facilitation and neuromuscular electrical stimulation on swallowing function in patients with chronic stroke and to provide basic data for swallowing rehabilitation in stroke patients. Method : The study involved 30 chronic stroke patients who visited ${\bigcirc}{\bigcirc}$ General Hospital in Daegu Metropolitan City between March and July, 2017. The subjects were randomly assigned to either an experimental group (n=15) or a control group (n=15). Both groups underwent traditional swallowing rehabilitation therapy for 30 minutes five times a week over a six-week period. The experimental group performed short neck flexor exercises, which are part of the proprioceptive neuromuscular facilitation, for 30 minutes three times a week over a six-week period. The control group performed neuromuscular electrical stimulation for 30 minutes three times a week over a six-week period. Based on its results, changes in the patients' swallowing function and degree of food intake were analyzed. Result : In terms of the ASHA NOMS scale and new VFSS scale, the experimental group and the control group showed statistically significant changes in ten sub-items and six sub-items, respectively. Statistically significant differences in one sub-item were found between the groups. Conclusion : PNF-based short neck flexion exercise appear to be effective at improving swallowing function of stroke patients with dysphagia.
