Purpose: The Abbe flap procedure has been used to correct disharmony of the upper and lower lips as well as for making a philtrum for patients with secondary cleft lip deformities. But the Abbe flap procedure adds two scars in addition to the prior operative scar on the upper lip. This study was conducted to determine the treatment outcomes of esthetic subunit excision of the scar on the philtrum and Abbe flap coverage for correction of cleft lip deformities with photogrammetric analysis. Methods: This study investigated a total of 11 patients with cleft lip deformities who underwent scar excision with Abbe flap coverage, and the patients were followed up for at least 6 months. Under general anesthesia, a mushroom-shaped Abbe flap was drawn on the lower lip with a width of 8 mm and a height 1~2 mm longer than that of the philtral midline. The epidermis and dermis of the scar on the upper lip were excised. In the cases with alar base depression, the orbicularis oris muscle was split vertically and transposed to the alar base. The Abbe flap was harvested as a pedicled flap containing a small amount of muscle and this was rotated 180-degree to be inserted into the upper lip. Mucosa, muscle, subcutaneous tissue and skin were closed in layers. The flap was divided at the 7~14 postoperative day. The postoperative outcomes were evaluated by using photogrammetric analysis. Three indices were measured from the standard clinical photographs taken before and after the surgery. For anthroposcopic assessment, observers described the postoperative outcomes using an ordinary scale method. Results: The postoperative values obtained in the photogrammetric analysis showed improvement as compared with the preoperative ones. Improved anthroposcopic outcomes were also noted. Conclusion: Scar excision and Abbe flap coverage were proven to be effective in improving protrusion and the height of the upper lip, the scar of the upper lip and the symmetry of Cupid's bow and the philtral column, as well as formation of the philtral dimple.
Parboiling, a popular technology used to protect rice from nutrient loss during milling and to increase the shelf-life of rice, was applied to barley kernels, and its effect on nutrient retention and chemical composition was evaluated. Before 36 days after ear emergence, barley kernels showed water content higher than 40%, and parboiling without presoaking resulted in at least 43% of gelatinization degree. This implies that soaking, an important step of parboiling, is dispensable for barley at milky stage. Parboiling did make little change in the appearance of the kernel after 31 days from ear emergence. Nonreducing sugars such as sucrose and raffinose remained unchanged while reducing sugars of barley was decreased by parboiling, with exception that maltose increased. Pearling led to decrease in crude protein, fat, fiber and minerals of barley sampled and parboiled on 36th day from ear emergence. Free sugars in the parboiled barley also was reduced with increasing pearling rate. Vitamin $B_1$ content of the parboiled barley was $260\;{\mu}g\;per\;100\;g$ as dry basis at 50% pearling rate, compared to $36\;{\mu}g$ for raw barley at same pearling rate. Thus parboiling appeared to be very effective in the retention of vitamin $B_1$ during pearling.
This study is a descriptive study which was done to examine the circumstances surrounding burn accidents in children in order to develop a burn prevention program. The subjects for the study were the mothers of 107 children admitted to two burn specialty hospitals in seoul and the mothers of 172 healthy children attending day care or kindergarten. The tool used in the study was developed by the researchers, pretested and refined. Cronbach's alpha was 0.72. Data collection was done between November 1995 and April 1996. Statistically analysis was done using SAS Version 6.04 and the data was analyzed using test, chi square, regression and logistic analysis. A suumary of the results shows the following : Eighty percent of the children in both groups lived in nuclear families but comparatively more of the children with burn accidents lived in apartments. More of the parents in the group of healthy children had university education and held white collar or professional jobs, while the parents of the children with burn accidents were slightly younger than the parents of the healthy children. but not significantly younger. A significantly greater number of families of children with burn accidents had more than one child and the characteristics of the children with burn accidents that they were more frequently boys, either first or last born and very active. Most of the burn accidents occurred in fall or winter. sometime between noon and midnight and the majority occurred in the home and were caused by hot liquid. In 86% of the cases emergency care was not given at home but the child was brought to the hospital emergency unit. Most of the burns were second degree or greater. involved the arms or legs. required admission, and 41.5% occurred when the parents were preparing or eating meals. In a test of knowledge of preventive measures, the mothers of children who had suffered burn accidents scored slightly higher than the mothers who had no experience with burn accidents, but this was not statistically significant. As to what to do in the case of a fire, the mothers of the healthy children had more knowledge about who to notify. but 70% of the mothers in both groups did not know how to escape from the house if it was of fire. 80 to 96% did not know what do to in case of a fire, such as rolling if clothes were on fire. 80% did not know what emergency care to give for a burn, and 74 to 87% did not know when it is appropriate to try to put out a fire. It can be concluded from this study that. since the results show that the most frequent situation which resulted in burn accidents was when the parents were not aware of the danger of burns or were not paying attention to the child. and when there were no protective devices to prevent burns. and that accidents most frequently occurred at home. the most effective way of preventing accidents is to develop in the parents a "safety mind", Since burn accidents in children are usually more severe than in adults. the physical. emotional. psychological and social damage is greater. In order to develop and awareness of this in the general public. the use of mass media. books and pamphlets and other educational media that provide education on prevention of burn accidents need to be utilized.
In this study, to produce Flammulina velutipes mushroom liquid spawn efficiently and effectively the effects of explosive aeration (supplying air with tiny bubbles) of the liquid culture medium on carbon dioxide concentration and residual sugar content in the medium on carbon dioxide concentration and residual sugar contentin the medium were measured. Carbon dioxide concentrations were measured at the outlet of the incubator. On the third day the explosive aeration greatly increased mycelial growth of the liquid spawn, and carbon dioxide concentration also greatly increased but decreased after 5 days. Free sugar contents in the liquid culture consistantly decreased up to 7 days and thereafter was not detected. The weight of the mycelia were maintained similar levels after 3 days. Total nitrogen content in the liquid medium constantly decreased during the 11days of explosive aeration. The content of free sugars in 7 days of culture was the lowest level, thus the inoculum incubated for 6~7 days was thought to be the most effective. Carbon dioxide concentration measurement at the outlet of the container during the liquid spawn incubation required low cost but was efficient to estimate the degree of mycelial growth to be used as a simple indicator.

The study was done to determine the proper transplanting dates and seedling ages of rice when mechanical transplanting was attempted. Heading dates of the Milyang #23, developed from Tong-il rice was delayed by delayed transplanting and the percent of filling grain was also low. The proper heading dates for the variety should be the first part of August and the transplanting should be done by the end of May. The presumed last days for the transplantation was considered early part of June. 30 to 40 days old seedlings were very effective to have healthy rooting systems. However, the Milyang #15 had shown more tolerance to the late transplantation than Milyang #23 and the degree of delaying heading dates due to the delayed transplantation was rather smaller than that of the Milyang #23. Even when the Milyang #15 was transplanted on June 30, the heading dates were around the middle of August and the ripening percentage was comparatively high and yield was also high. Therefore, the proper heading dates of the Milyang #15 might be around the middle of August and transplanting dates should be the first part of June. The possible last dates of transplantation of the Milyang #15 was assumed to be the last days of June and the proper seedling ages would be 20 to 30 day after sowing.
The use of water by cities is increasing owing to industrialization, the concentration of population, and the enhancement of the standard of living. Accordingly, the amount of waste water is also increasing, and the degree of pollution of the water system is rising. In order to solve this problem, it is necessary to remove organisms and suspended particles as well as the products of eutrophication such as nitrates and phosphates. This study developed a high-end treatment engineering solution with maximum efficiency and lower costs by researching and developing a advanced treatment engineering solution with the use of Biosorption. As a result, the study conducted a test with a $50m^3/day$ Pilot Scale Plant by developing treatment engineering so that only the secondary treatment satisfies the standard of water quality and which provided optimal treatment efficiency along with convenient maintenance and management. The removal of organisms, which has to be pursued first for realizing nitrification during the test period, was made in such a way that there would be no oxidation by microorganisms in the reactor while preparing oxygen as an inhibitor for the growth of microorganism in the course of moving toward the primary settling pond. The study introduced microorganisms in the endogeneous respiration stage to perform adhesion, absorption, and filtering by bringing them into contact with the inflowing water with the use of a sludge returning from the secondary settling pond. Also a test was conducted to determine how effective the microorganisms are as an inner source of carbon. The HRT(Hydraulic Retention Time) in the nitrification tank (aerobic tank) could be reduced to two hours or below, and the stable treatment efficiency of the process using the organisms absorbed in the NAR reactor as a source of carbon could be proven. Also, given that the anaerobic condition of the pre-treatment tank becomes basic in the area of phosphate discharge, it was found that there was excellent efficiency for the removal of phosphate when the pre-treatment tank induced the discharge of phosphate and the polishing reactor induced the uptake of phosphate. The removal efficiency was shown to be about 94.4% for $BOD_5$. 90.7% for $COD_{Cr}$ 84.3% for $COD_{Mn}$, 96.0% for SS, 77.3% for TN, and 96.0% for TP.

Purpose: In the partial thickness burn management, despite of several advantages, the use of human amniotic membrane has been limited. The authors applied dried bovine amniotic membrane(DBAM) to overcome disadvantages of amniotic membrane for partial thickness burn and compared the effectiveness with cultured allogenic keratinocytes(CAK) that have been recently used for the management of burn. Methods: 16 patients with partial thickness burn, the mean age of 38 ranging 12 to 59 years, between August 2007 and May 2008 were assigned to this study. Either DBAM or CAK was applied, and the secondary dressing was removed on the following day. To compare treatment effect, time for epithelization, Vancouver scar scale and chromameteric results were evaluated. Results: The time for epithelization of DBAM was 10.1 days, that of CAK was 9.1 days, and they were shorter than the previous 2 - 3 weeks. At the follow up Vancouver scar scale was 2.8 for DBAM and 3.0 points for CAK and showed good results. The result of chromameter showed that the $L^*$, $a^*$, and $b^*$ values of the area applied DBAM were 60.1, 13.6, and 13.3, respectively, and the values of the area applied CAK were 60.1, 12.4, and 12.4, respectively. It was found that the skin color of the healed area after burn was darker, the redness was higher, and the yellowness was lower. After dressing, significant side effects were not observed, and in the cases of applying CAK, it was inconvenient as the moving area had to be fixed. Conclusion: With CAK, DBAM has several advantages such as the shortening of the epithelization period, reduction of scar and pigmentation, and convenient application, etc. Thus it is an effective method for the partial thickness burn management.
To investigate the alleviative effect of white tea water extract on the inflammation and skin barrier damage, skin aging animal model was produced by the irradiation of UVB to the backs of hairless mice for 12 weeks. And then experimental materials were applied topically for 4 weeks. At the 28th day of experiment, positive control (PC, 0.01% retinoic acid treatment) and experimental groups (E1, 1% white tea water extract treatment; E2, 2% white tea water extract treatment) had significantly (p<0.001) lower values of both skin erythema index and transepidermal water loss (TEWL) than the control (C, saline treatment) group. The appearance of mast cell and the degree of its degranulation in dermal and subcutaneous layers were remarkably reduced in E1 and E2 groups compared to the C group. It is found that white tea water extract is effective in skin barrier damage and inflammation in hairless mouse.
This research has been conducted to determine the effect that the visually handicapped's participation in an aerobic exercise program has on cardiorespiratory function and arterial pulse wave. The subjects of this research were 20 people who have a 1st degree visual impairment. They recognized the purpose of this research and agreed to take part in it. After receiving agreements from their guardians, we divided them into an exercise group of 10 and a comparison group of 10 at random. The exercise group conducted a 50-70%HRmax treadmill exercise for 60 minutes a day, five times a week, for 12 weeks, including warm up and warm down exercises. We then conducted a two-way repeated ANOVA, which regards the period of exercise and the two groups as independent variables. The follow-up verification for exercise periods according to each group was carried out with a paired t-test. The statistical significance level was p<.05. The following are the results of this research. First, the weight and body fat of the experiment group after exercise show a meaningful reduction compared to before the exercise program (p<.05).Second, the VO2max, HRmax, and VEmax of the experiment group after exercise show a meaningful increase compared to before the exercise program (p<.05). Third, the arterial pulse wave of the experiment group after exercise display a meaningful increase compared to before the exercise program (p<.05). Fourth, the systolic blood pressure of the experiment group after exercise does not show a meaningful reduction compared to before the exercise program (p>.05). These results prove that the visually handicapped's participation in an aerobic exercise program is effective in the improvement of their cardiorespiratory function, bloodstream circulation function and blood vessel function.
Copris tripartitus Waterhouse is a coprophagus insect which enhances the soil fertility as conveying dung into the soil. We compared preimaginal development, mortality, and size of C. tripartitus at various temperature condition (15, 17.5, 20, 25, 27.5, 30). Total preimaginal periods ranged from 118.0d at $17.5^{\circ}C$ to 49.3d at $27.5^{\circ}C$. Development threshold temperature (DT) and total effective temperature for the development of egg, larva, pupa and for complete development (egg to emergence) were 12.1, 11.2, 12.1 and $9.2^{\circ}C$ and 82.7, 462.0, 225.7 and 947.2 degree days, respectively. The mortality of egg and larva was the lowest at $25^{\circ}C$. The optimum temperature for hatchability and on the development of C. tripartitus was estimated to the $25^{\circ}C$.
