  • Further treatment facility using various filter materials was evaluated to treat effluent of constructed wetland. Further treatment facility was installed with 1m length in outlet of 3 constructed wetland (unplanted constructed; reed bed constructed wetland; cattail bed constructed wetland) using 3 filter materials (slag, activated carbon, oyster shell). Flow rate of three further treatment facility was 63 $m^3$/day (slag), 19 $m^3$/day (activated carbon), and 81 $m^3$/day (Oyster shell). COD removal rate of slag, activated carbon, and oyster shell was 6 %, 24 %, 1 %, and removal mass was 32 g/day, 30 g/day, and 5 g/day, respectively. All of further treatment facility was effective to removal organic materials. T-N and T-P removal rate of activated carbon was 24 % and 4 %, and slag and oyster shell was not effective to remove T-N and T-P. Overall, further treatment facility was effective to remove organic mater, constructed wetland combined with further treatment facility can remove nutrient and organic matters effectively.

  • Three experiments were conducted to investigate the hypothesis that cows grazing on pasture produce the highest proportion of c-9 t-11 CLA in milk fat and no further increase can be achieved through supplementation of diets rich in linoleic acid, such as full-fat extruded soybeans or soybean oil. In experiment 1, 18 lactating Holstein cows were used in a randomized complete block design with measurements made from wk 4 to 6 of the experiment. In experiment 2, three cannulated lactating Holstein cows were used in a $3{\times}3$ Latin square design. Each period was 4 wk with measurements made in the final wk of each period. Cows in both experiments were assigned at random to treatments: a, conventional total mixed ration (TMR); b, pasture (PS); or c, PS supplemented with 2.5 kg/cow per day of full-fat extruded soybeans (PES). In both experiments, feed intake, milk yield, milk composition, and fatty acid profile of milk and blood serum were measured, along with fatty acid composition of bacteria harvested from rumen digesta in experiment 2. In experiment 3, 10 cows which had continuously grazed a pasture for six weeks were assigned to two groups, with one group (n = 5) on pasture diet alone (PS) and the other group (n = 5) supplemented with 452 g of soy oil/cow per day for 7 d (OIL). In experiment 1, cows in PS treatment produced 350% more c-9, t-11 CLA compared with cows in TMR treatment (1.70 vs. 0.5% of fat), with no further increase for cows in PES treatment (1.50% of fat). Serum c-9, t-11 CLA increased by 233% in PS treatment compared with TMR treatment (0.21 vs. 0.09% of fat) with no further increase for cows in PES treatment (0.18% of fat). In experiment 2, cows in PS treatment produced 300% more c-9 t-11 CLA in their milk fat compared with cows in TMR treatment (1.77 vs. 0.59% of fat), but no further increase for cows in PES treatment (1.84% of fat) was observed. Serum c-9, t-11 CLA increased by 250% for cows in PS treatment compared with cows in TMR treatment (0.27 vs. 0.11% of fat), with no further increase for cows in PES treatment (0.31% of fat). The c-9, t-11 CLA content of ruminal bacteria for cows in PS treatment was 200% or more of TMR treatment, but no further increase in bacterial c-9, t-11 CLA for cows in PES treatment was observed. Supplementation of soy oil in experiment 3 also did not increase the c-9 t-11 CLA content of milk fat compared with cows fed a full pasture diet (1.60 vs. 1.54% of fat). Based on these findings, it was concluded that supplementing with feeds rich in linoleic acid, such as full-fat extruded soybeans or an equivalent amount of soy oil, to cows grazing perennial ryegrass pasture may not increase milk fat c-9 t-11 CLA contents.

  • This paper claims Hale and Keyser's (1992, 1993a, 2001) Lexical Relational Structure (LRS) theory should be slightly extended by allowing the syntactic principles for the “referential” component to apply to the “manner” component. Then, it shows this extension allows us to deal with most of Clark and Clark's (1979) denominal verbs, except that cases like butcher may further demand Hale and Keyser's (2001) p-signature copying treatment. It also argues that this extension is further supported by a more satisfactory treatment of the distribution of non-bridge verbs, and of an asymmetry in ditransitive passives.

  • Gingival recession is one of the common mucogingival problems during the orthodontic treatment. The causes of the gingival recession are similar to gingival recession in patients with periodontal diseases. Accumulation of bacterial deposits around the natural teeth induces the gingival inflammation and gingival recession occurs in the teeth with the lack of the supporting bone. However, malpositioned teeth which are labially positioned teeth or rotated teeth are more risky for gingival recession. Once root is exposed to oral cavity due to gingival recession, the orthodontic tooth movement is compromised and esthetic problems appeared. In addition, excessive gingival recession over the mucogingival junction jeopardizes the oral hygiene control, which has a risk of further gingival recession and bone loss around the tooth. To cover exposed root or to prevent further gingival recession, mucogingival surgery with gingival graft is recommended for the patients under orthodontic treatment. This case report aimed to present the mucogingival treatments of gingival recession observed during orthodontic treatment. Case I had had initial slight gingival recession before the orthodontic treatment. However, during the retraction phases, the gingival recession progressed and the periodontal treatment was referred. In case II, miller Class III gingival recession was occurred after correction of rotation. Both cases were treated by coronally advanced flap with free gingival grafts and recovered to the level of adjacent teeth despite of complete root coverage was not achieved in Case II. After periodontal treatment, orthodontic treatment was successfully completed. In conclusion, mucogingival surgery during the orthodontic treatment is recommended for the successful orthodontic treatment as well as periodontal health.

  • Pilot study was performed to examine the feasibility of the pond system for further polishing of treatment wetland effluent from December 2000 to June 2001. The wetland system used for the experiment was highly effective to treat the sewage during the growing season, but it was less effective and its effluent was still high to discharge to the receiving water body. Therefore, the wetland effluent may need further treatment to prevent water quality degradation. Pond system could be used to hold and further polish the wetland effluent during the winter season and ots feasibility was evaluated in this study. Additional water quality improvement was apparent in the pond system during winter season, and the pond effluent could be good enough to meet the effluent water quality standards if it is properly managed. Timing of the pond effluent discharge appears to be critical for pond system management because it is a closed system and whole water quality constituents are affected by physical, chemical, and biological pond environments. Once algae started to grow in mid-April, constituents in the pond water column interact each other actively and its control becomes more complicated. Therefore, upper layer of the pond water column which is clearer than the lower layer my need be discharged in March right after ice cover melted. In the experiment, water quality of the upper water column was markedly clear in March than ant other times probably because of freezing-thawing effect. The remaining lower water column could be further treated by natural purification as temperature goes up or diluted with better quality of wetland effluent for appropriate water uses. This study demonstrated the feasibility of pond system for subsequent management of wetland effluent during the winter season, however, more study is needed for field application.

  • A new treatment system for animal waste water has been developed as an alternative to the activated sludge process. It consists of two treatments; one is operated with 7 tanks, and the other is soil and plant cultivation bed. Aerobic microorganisms are added to the influent water in the tanks where the water is aerated so that the microbes utilize the pollutants, while sedimentation removes the indigestible solids. In the secondary treatment the water, which has already received a primary treatment, is filtered through soil where it also receives treatment by soil organisms. In addition there is transpiration of water and absorption of minerals by plants. In the primary treatment BOD, SS, coliforms (E. coli), TP and total bacteria were removed 79-99%, but COD and TN were removed only 58% and 36%, respectively. In the secondary treatment removal of nutrients proceeded further, and 93-99% of pollutants were removed. The treated waters met the quality standard of discharge water in Japan except for TN, which was in too great a concentration to meet discharge standards. This problem requires further study.

  • Today most of farmers rear the silkworms two time a year, spring and autumn (Fig. 1). But from now on, we can rear whenever mulberry tree is grown, and it is expected that we can rear many times (Fig.2). Because the silkworm eggs can not always be hatched, we have to study a special method for rearing many times a year. The writer, in these problems, hatched the silkworm eggs from the beginning of June to the beingning of September, once every 10 days, and reard 10 times. The results are as follows; 1) The silkworm eggs for the beginning and middle of June have no difference between the double cooling method and the single cooling method. But the eggs for the end of June in the double cooling method is better. 2) For the silkworm eggs for the middle of July, the cooling method after acid treatment for eggs is better. 3) For the silkworm eggs for the end of July, the reeling method after acid treatment is better. But it is needed to study the short artificial treatment. 4) For the eggs for the beginning of August, the further study of the short artificial treatment is also needed. 5) For the eggs for the middle of August, after cooling treatment is better. The short artificial treatment is possible for them. But further study is needed. 6) For the eggs for the beginning of September, after cooling treatment is needed for further study.

  • Objectives The purpose of this study is to compare the effects of ShinBaro pharmacopuncture and Jungsongouhyul pharmacopuncture on whiplash injury by traffic accident. Methods This study was carried out on 30 patients who received treatment in Jaseng Hospital of Korean Medicine. 30 patients were divided ShinBaro pharmacopuncture group and Jungsongouhyul pharmacopuncture group. Visual analog scale (VAS) and neck disability index (NDI) were compared after treatment. Results 1) Both the ShinBaro group and Jungsongouhyul group showed significant improvement in the visual analog scale (VAS) and neck disability index (NDI) after 3 weeks of treatment. 2) The VAS and NDI of the ShinBaro group decreased gradually with treatment. The VAS scores showed significant improvement up to week 2, but although week 3 showed further improvement compared to week 2, the difference did not reach statistical significance. The NDI scores showed significant improvement consistantly throughout the treatment period. 3) The VAS and NDI of the Jungsongouhyul group decreased with treatment also. The VAS scores significantly improved up to week 2, but though week 3 showed further improvement in comparison to week 2, the difference did not reach statistical significance. The NDI scores showed significant improvement consistantly throughout the treatment period. 4) Although the ShinBaro group showed a swifter decline than the Jungsongouhyul group in both VAS and NDI scores, the difference was not statistically significant. Conclusions We found out that ShinBaro pharmacopuncture group and Jungsongouhyul pharmacopuncture group is effective and useful in whiplash injury by traffic accident. And, further studies will be needed.

  • Objective: To evaluate early treatment for extranodal natural killer/T cell lymphoma (ENK/TCL) in China and provide reference for clinical treatment of these patients. Methods: Computer-based retrieval was performed in PubMed, CNKI, CBM, VIP and WanFang Data to search for randomized controlled trials (RCTs) of treatment for early ENK/TCL, and a meta-analysis was conducted with RevMan 5.0 software. Results: A total of 11 RCTs, including 871 patients, were selected, of which the first radiotherapy had a higher complete response (CR) than the first chemotherapy [OR=14.16, 95%CI (8.68, 23.10), P<0.00001] and CR was not different between combined treatment group and radiotherapy group [OR=1.86, 95%CI (0.47, 3.58), P=0.61], but long-term survival rate was higher with combined treatment[OR=1.88, 95%CI (1.09, 3.19), P=0.02]. No difference in survival rate was observed between radio-chemotherapy and chemo-radiotherapy groups [OR=1.11, 95%CI (0.73, 1.69), P=0.63]. Conclusions: Radiotherapy is of great significance in the treatment of early ENK/TCL, but combined therapy could further enhance long-term survival rate of patients. This conclusion still requires further confirmation using RCTs with high quality and large sample size.

  • A pilot study was performed to examine the feasibility of the pond system for further polishing of treatment wetland effluent to agricultural reuse of reclaimed water. The constructed wetland and pond system was installed in Konkuk University and the effluent from septic tank of school building was used as an influent to the wetland system. The effluent of the wetland was used as an influent to pond systems. The influent concentrations of total coliform(TC), fecal coliform (FC), and E. coli were about $10^5$MPN/100 ml, and they were reduced to less than 10,000 MPN/100 ml on average after wetland treatments, showing over 95 % removal. And they were further reduced to less than 1,000 MPN/100 ml in average, showing over 85∼93 % removal after pond treatment. Turbidity and SS were improved effectively on average and their pond effluent concentration was about 4.5 NTU and 9.8 mg/L in average, respectively Average $BOD^5$ concentrations were also reduced substantially to 9.3 mg/L with about 83 % removal rate after wetland and pond treatment systems. Nutrients removal was relatively low and removal rate for T-N and T-P was less than 43 and 44%, respectively after wetland and pond treatment. Considering stable performance and effective removal of bacterial indicators as well as other water quality parameters, low maintenance, and cost-effectiveness, pond system was thought to be an effective and feasible alternative for agricultural reuse of reclaimed water. This paper describes a preliminary result Iron pilot study and further investigations are recommended on the optimum design parameters before full scale application.
