Ten cleft palate patients were operated with reconstruction of levator sling without pushback for the purpose of not to make raw surface in the anterior portion of hard palate to prevent maxillary retrognathia. Speech was evaluated by using speech assessment list. Maxillary growth was not evaluated due to in-growing age in majority patient. The report will be followed in next chance. We could impose the significance in clinical application of levator sling palatoplasty without any complications but improving speech.

For the Exp. 1, a total of sixty pigs(15.95${\pm}$0.09kg average initial body weight) were used in a 28-d growth assay to determine the effects of extruded chinese corn on growth performance and nutrient digestibility in nursery pigs. Dietary treatments included 1) UCORN(U.S. corn-SBM based diet), 2) CCORN(Chinese corn-SBM based diet) and 3) ECCORN(Extruded Chinese corn-SBM based diet). Overall period, average daily gain of pigs fed ECCORN diet was higher than that of pigs fed CCORN diet(547 vs 522 g/d), however, there was not significant difference. On day 10 of the experiment, pigs fed UCORN and ECCORN diet had significantly increased in DM and DE digestibilities compared to pigs fed CCORN diet(P〈0.05). Also, on day 24 of the experiment, pigs fed UCORN and ECCORN diet had a significant increase in DM digestibility compared to pigs fed CCORN diet(P〈0.05). Pigs fed ECCORN diet had significantly increased DE digestibility compared to pigs fed CCORN diet(P〈0.05). For the Exp. 2, three cannulated barrows(54.09kg average initial body weight) were used to determine the apparent ileal digestibilities of amino acids and nutrient digestibility of extruded corn in finishing pigs. Dietary treatments were the same as in Exp. 1. Apparent ileal digestibility of cystine was greater for UCORN and ECCORN than for CCORN(P〈0.05). Apparent digestibility of DM at the total tract was greater for UCORN and ECCORN than for CCORN(P〈0.05). Pigs fed UCORN and ECCORN diet had a significant increase in apparent total tract digestibility of N compared to pigs fed CCORN diet(P〈0.05). In conclusion, the results obtained from these feeding trials suggest that the extruded corn for nursery pigs had affected growth performance and DM and DE digestibilities. In finishing pigs, extruded corn was an effective means to improve apparent total tract digestibilities of DM and N.

This study was conducted to investigate the influence of feeding illite(yellow soil component) on meat quality of pork. 40 pigs were fed with commercial formulated feed (control group) and 1% illite added feed(treatment group). Pigs grown up to 100~110kg of weight were slaughtered in commercial abattoir. After chilling for 24hours, samples were collected from M. longissimus dorsi muscle, and stored at $4\pm$$1^{\circ}C$ for analyses. The physico-chemical properties was determined during storage days as follows. Ultimate pH was not significantly different between control and treatment(pH 5.58 and 5.60, respectively). Water-holding capacity measured using filter paper press method of the treatment group was slightly higher than that of the control group. Cooking loss of treatment group were significantly lower than that of the control group at 1 and 7 days(p〈0.05). Shear force between control and treatment group was not different. L*- and a*-value were not significantly different between the two groups(p〉0.05), but b*-value of treatment group was lower than that of the control group(p〈0.05). The drip loss of all samples was increased with storage days, and that of the treatment group was significantly lower than that of the control at 1 and 3 day storage. Meat color measured using NPPC pork quality standards was not significantly different between the two groups(p〉0.05), but marbling content of the treatment group was significantly higher than that of the control group(p〈0.05). Sensory characteristics of, flavor taste and tenderness did not show significant differences(p〉0.05), but juiciness of the treatment group showed higher value than that of the control group(p〈0.05)

The feasibility of incorporating Cynanchi wilfordii powder as a value-added food ingredient in convenient food products was investigated using yanggaeng as a model system. C. wilfordii powder was incorporated into yanggaeng at 0, 2, 4, 6, and 8% weight amounts based on total weight of cooked white bean and C. wilfordii powder. pH increased significantly, and moisture content ranged from 45.40% to 47.40% with increasing levels of C. wilfordii powder (P<0.05). In terms of color, lightness, redness, and yellowness increased significantly (P<0.05) with increasing levels of C. wilfordii powder. Hardness significantly decreased with higher amounts of C. wilfordii powder (P<0.05). Total polyphenol content and DPPH radical scavenging activity were significantly influenced by addition of C. wilfordii powder, and they increased significantly as C. wilfordii powder concentration increased (P<0.05). Finally, consumer acceptance test indicated that the highest levels of C. wilfordii powder (8%, w/w) had considerable adverse effects on consumer preferences in general. In contrast, yanggaengs with moderate levels of C. wilfordii powder (2%, w/w) are recommended (with respect to overall preference score) to take advantage of the functional properties of C. wilfordii powder without sacrificing consumer acceptability.

전 국토의 약 7.6%를 차지하고 있는 밭은 장마철이나 집중호우에 의해 하천의 탁수문제를 유발할 뿐만 아니라, 수생태계에도 악영향을 미치기 때문에 비점오염원을 저감시켜야 한다. 이러한 비점오염원을 줄이기 위한 여러 최적관리방법 중 침사구를 밭의 유출부에 적용하여 비점오염물질의 유출저감효과를 평가 하고자 하였다. 평가 방법은 6개(각 110m2)의 무밭을 조성하여 무 재배기간(2011년 4월부터 7월) 동안 시험포에서 발생하는 강우유출수를 1.125 m3($1.5m{\times}1.5m{\times}0.5m$) 크기의 침사구 3개로 각각 유입되도록 하였다. 침사구로 유입된 유출수는 토양으로 침투 및 저류 또는 증발되도록 하였고, 강우에 의한 유출수의 양이 침사구의 용량보다 클 경우 침사구 유출부를 통해 유출되도록 하였다. 연구 결과 평균 64.1%의 유출량 저감효과가 있는 것으로 나타났으며, 수질농도는 BOD5 39.0%, SS 62.1%, CODMn 43.4%, DOC 43.5%, T-N 40.0%, T-P 41.2%의 저감효과가 있는 것으로 나타났다. 유출량과 수질농도를 고려한 오염부하 저감효과는 유출량이 적었던 #2와 #3의 침사구에서 모든 수질항목에서 각각 80%와 90% 이상의 저감효과가 나타났다. 본 연구의 결과를 바탕으로 밭에서 발생하는 비점오염물질 저감을 위해 밭의 유출부에 작은 웅덩이와 같은 침사구를 설치할 경우 비점오염을 저감하는데 매우 효과적인 것으로 판단된다. 또한 강우유출수가 적을 경우 침사구에 의한 유사량의 저감효과도 매우 클 것으로 판단된다. 따라서 밭에서 발생하는 비점오염원을 줄이기 위해서는 본 연구와 같이 밭의 지표를 볏짚이나 다른 피복재 등으로 피복하여 토양의 이동을 최소한으로 줄여 오염부하량을 저감하고, 유출이 발생할 경우 밭의 유출부에 침사구를 설치하여 하천으로 유입되는 오염물질을 저감해야 할 것으로 판단된다.

In current, there has not been the evaluation model for the optimum design of the multi-utility tunnel by considering urban type and size, the function of surrounding road and feasibility analyses with respect to construction method, and arrangement of accommodation facilities inside multi-utility tunnel. Thus, in this study, we developed the evaluation model for the optimum design of the multi-utility tunnel before and after the decision of the multi-utility tunnel installation. In this paper, we have selected the Deming cycle which is used in various fields among several decision methods for optimizing the design. For the purpose of reflecting the various factors in the design of the multi-utility tunnel, 11 higher indicators were set up to lead to more detailed approaches. In addition, based on the "Plan-Do-Check-Action (PDCA)" circulation method, we can realize the installation of the multi-utility tunnel and design more efficiently through the first phase for conception and the second phase for optimization, and develop the program for the evaluation model accordingly.

In this paper, we propose a method to determine whether to install the accommodation facility of the multi-utility tunnel more effectively in the basic planning phase, and to set up an evaluation system to determine the configuration and kind of accommodation facility. For the configuration of the accommodation facility, 98 alternatives were analyzed for 7 accommodation facility. For the evaluation system of the accommodation facility, index related to feasibility and economic in basic planning phase were selected. The evaluation system classified as spatial, effective, and cost evaluation was presented reflecting the selected index, and AHP analysis was performed for weight setting. The results of this study will be helpful for users including designers to shorten the time and increase the efficiency in the process of determining accommodation facility of the multi-utility tunnel in basic planning phase.
