The purpose of this study is to find ways of evaluating the suitability of sites being considered for development of different types of parks in the vicinity of yangmock-myun kyoung buk, where a large project(as large as about14.0$km^2$) has been planned. The results are as follows. Three surveys for selecting the assessment indicators were performed. ${\cdot}$ The first survey analyzed the importance of 23 selected assessment indicators based on a review of existing literature review and an on-the-spot research. ${\cdot}$ The second survey selected assessment indicators for each park type. ${\cdot}$ The third survey computed additive values of selected assessment indicators by the park types. It used a method of standardizing the average importance of indicators by making their sum equal to 10. These additive values were then multiplied by each grade of indicators to make a final evaluation. An evaluation of the site-suitability of park types was performed twice. The purpose of the first evaluation was to figure out how much each type met the minimum requirements targeted for all landscape types. The minimum requirements were derived by using a relative comparison between the standard of value rating of the assessment indicators, which was over the medium magnitude on the importance analysis, and the result of field research. A second evaluation estimated the targeted sites that met the minimum requirements. Value ratings of second assessment indicators were quantitatively divided as 1 to 3 grade and the evaluation scores were added, giving an additive value for each assessment indicator. The evaluation score on each park type was rated on a scale of 1 to 3 according to their averages, (from lowest to highest). Since this evaluation model of the site suitability on park types only focused on the 'face' of space in this study, additional analysis is necessary for setting the evaluation model and incorporating the overall impact of space, network connection and other factors, considering 'spot', 'line' and 'face' aspects of space.

Objectives: This study aimed to develop a tool for assessing foreigners' understanding of oral health information in Korea called the Test of Korean Functional Health Literacy in Dentistry(TOKFHLiD) and examined validity and reliability of the tool. The TOKFHLiD consists of two literacy assessment parts: Dental Information Sentence(DIS) aims to assess one's literacy of sentences containing oral health information. Dental Information Document(DID) aims to assess one's numeracy and literacy of documents containing oral health information. Methods: Twenty eight preliminary questions were developed based on various medical care literature such as the agreement to diagnosis and treatment and the treatment precautions. DID using 14 preliminary questions was developed based on the appointment card, the treatment schedule, and labels on oral care products. The 42 preliminary questions in the DIS and the DID were subsequently put through four separate expert reviews, in which questions with content validity score of less than 0.8(13/15 points) were corrected and modified by five dental experts and then were corrected for language errors by two Korean language experts. The preliminary assessment tool was tested on 153 Koreans, and ${\chi}^2$ test was performed on the ratio of respondents who comprehended each question, the ratio of respondents who chose the correct answer for each question with a significance level of 0.05. Results: Of the 42 preliminary questions, 1 question in DIS and 1 question in DID, for which the ratio of Korean respondents who chose the correct answers did not exceed the acceptable level of 80%, were excluded and a final assessment tool was completed with 40 questions. Conclusions: Following the development and application of the tool, examination of the TOKHLiD for validity and reliability revealed that this assessment tool is adequate for assessing oral health information literacy of foreigners who are using oral hygiene medical services in Korea.

This study was conducted to investigate the dietary effect of total mixed rations (TMR) containing brewers grain, soybean curd and rice straw, respectively, on growth performance and carcass characteristics of Hanwoo steers. Twenty four Hanwoo steers (average body weight 168 kg) in 6 months age were randomly allocated to 4 experimental groups, which contained 6 animals per group during 22-months feeding trial. The treatment was composed of the group fed concentrate and rice straw separately (T1), the group fed TMR containing brewers grain (T2), the group fed TMR containing soybean curd (T3) and the group fed TMR containing rice straw (T4). Body weight (BW) was not different among treatment groups during the growing and middle fattening period. However, it was significantly greater in T4 group than in T2 group on the final BW (p<0.05). Average daily gain was significantly greater in TMR groups compared to T1 group on the growing and late fattening (p<0.05). However, it was not different in total average. Dry matter intake tended to be increased in TMR groups. The feed conversion ratio was significantly lower in T4 group compare to T2 group (p<0.05). According to the yield traits, carcass weight of T1, T2, T3 and T4 were 389.0, 368.4, 387.5 and 384.3 kg, respectively. The back fat thickness, rib-eye area, and yield index were not different among the groups. Meat color, fat color, texture and maturity were not significantly different among groups. However, marbling score and appearance rate of meat quality grade of over $1^+$ were greater in T2 and T3 groups compare to other groups. Therefore, these results indicated that TMR with brewers grain and soybean curd may be ameliorated the growth performance and carcass characteristics of Hanwoo steers.

Purpose: The purpose of this study was to determine how many of our patients who had had anterior cruciate ligament (ACL) reconstruction returned to their previous levels of sports and to identify why not doing so. Material and Methods: We evaluated 43 knees with a minimum of two years follow-up among whom undergoing 109 ACL reconstruction from September 2003. The mean age of patients was 26 years (17 to 45 years) Clinical results was evaluated according to the Lysholm Knee scores, Tegner activity score, subjective IKDC questionnaires, objective IKDC evaluation form and KT-1000 arthrometer. Results: The overall clinical results demonstrated significant improvement at the final follow-up comparing to preoperative data (P<0.05). Among 43 patients, 25 patients (58%) returned to their previous level of sports and 18 patients (42%) did not. Of whom, 11 patients (61%) were not able to return to sports due to fear to re-injury and 7 patients (39%) suffered from instability and pain. The differences in the Lysholm Scores, KT-1000 arthrometer and subjective IKDC in the 3 groups of patients by ANOVA test were found to be statistically significant (P<0.001). Although there is no difference in objective IKDC and KT-1000 arthrometer, the difference was observed in Tegner activities, subjective IKDC obtained by those who returned to sport and those who had fear to reinjury (P<0.001). Conclusion: This study showed that a quater of patients could not return to their previous level of sport after ACL reconstruction because of fear to reinjury. We thought that not only improving the technique of ACL reconstruction and systemic rehabilitation but also considering psychological factor of patients could allow more patients to return to the previous level of sports.

Purpose: We evaluated the clinical outcome after arthroscopic repair in full thickness rotator cuff tears with and without delamination. Materials and Methods: From March 2006 to October 2008, we included 48 consecutive shoulders (31 males, 17 females; mean age 57.6 years; 45~68) who had arthroscopic double row repair for fullthickness tears of the rotator cuff. Mean rotator cuff tear size was 2.8 cm (range: 1.2~3.6) and the techniques of tendon-to-bone fixation varied according to the presence of delamination; separate row fixations of bursal and articular layer were used in delaminated tear. The mean follow-up was 26 months (range: 18~33) and functional and structural results were evaluated by American Shoulder and Elbow Surgeons (ASES), University of California at Los Angeles (UCLA) scale, isokinetic strength testing and magnetic resonance imaging (MRI) obtained mean 8 months (range:6~13) postoperatively. The patterns of delamination, age, sex, symptom duration, size of tear, satisfaction rate, retear rate ware compared and significance was set at p values < 0.05. Results: Postoperative functional shoulder score improved significantly in 44 shoulders (91.7%). Delamination was observed in 15 shoulders (31%) and it extended proximally and posteriorly in the majority of shoulders, and the articular layer was thicker (8/15, 53%) and more retracted (9/15, 60%) compared with the superficial bursal layer. Final follow up functional shoulder scores showed no differences between non-delaminated and delaminated tears and the presence of delamination had no correlations with sex, symptom duration, tear size and satisfaction rate, however, older age had more delaminated tears (p=0.041). Follow up MRI in 29 shoulders revealed that fourteen (48%) shoulders had complete healing; nine (31%), partial healing; six (21%), complete retear but the half of the retear group showed favorable clinical results. 79% (15/19) in non-delaminated tear and 80% (8/10) in delaminated tear were judged as healed tendon on MRI and double-layer double row repairs in delaminated tears resulted in nearly same rate of structural integrity of single-layer double row repairs (p=0.165). Conclusion: The incidence of delamination in our series was 31% and older age had more delaminated tears. Sex, symptom duration, preoperative size of the tear, functional results and satisfaction rate had no significant correlations with the presence of delamination. Nearly the same postoperative structural integrity was noted in both delaminated and non-delaminated tears.

With the development of the 4th industrial, research is being conducted to prevent diseases and reduce damage in various fields of science and technology such as medicine, health, and bio. As a result, artificial intelligence technology has been introduced and researched for image analysis of radiological examinations. In this paper, we will directly apply a deep learning model for classification and detection of pneumonia using chest X-ray images, and evaluate whether the deep learning model of the Inception series is a useful model for detecting pneumonia. As the experimental material, a chest X-ray image data set provided and shared free of charge by Kaggle was used, and out of the total 3,470 chest X-ray image data, it was classified into 1,870 training data sets, 1,100 validation data sets, and 500 test data sets. I did. As a result of the experiment, the result of metric evaluation of the Inception V3 deep learning model was 94.80% for accuracy, 97.24% for precision, 94.00% for recall, and 95.59 for F1 score. In addition, the accuracy of the final epoch for Inception V3 deep learning modeling was 94.91% for learning modeling and 89.68% for verification modeling for pneumonia detection and classification of chest X-ray images. For the evaluation of the loss function value, the learning modeling was 1.127% and the validation modeling was 4.603%. As a result, it was evaluated that the Inception V3 deep learning model is a very excellent deep learning model in extracting and classifying features of chest image data, and its learning state is also very good. As a result of matrix accuracy evaluation for test modeling, the accuracy of 96% for normal chest X-ray image data and 97% for pneumonia chest X-ray image data was proven. The deep learning model of the Inception series is considered to be a useful deep learning model for classification of chest diseases, and it is expected that it can also play an auxiliary role of human resources, so it is considered that it will be a solution to the problem of insufficient medical personnel. In the future, this study is expected to be presented as basic data for similar studies in the case of similar studies on the diagnosis of pneumonia using deep learning.

Purpose : This study compared bone ages measured by the Greulich-Pyle (GP) and Tanner-Whitehouse 3 (TW3) methods and investigated the differences in predicted adult heights measured by Bayley-Pinneau (BP) and TW3 methods. Methods : Bone ages were assessed from left-wrist radiographs by two investigators, one for each GP and TW3 methods in 85 normal children, 30 precocious puberty girls, and 30 constitutional growth delay boys. The differences between the measured predicted adult heights using the BP and TW3 methods were compared in each group. Results : The bone age measured by the TW3 method was less than that by the GP method in normal children. The predicted adult heights measured by the two methods showed no significant difference in normal boys, while the predicted adult height measured by the TW3 method was higher than that by the BP method for normal girls ($156.4{\pm}4.7$ cm vs. $158.9{\pm}3.8$ cm, P<0.01) and for precocious puberty girls ($156.3{\pm}4.0$ cm vs. $159.3{\pm}4.2$ cm, P<0.01). In contrast, the predicted adult height was higher from the BP method than from the TW3 method in constitutional growth delay boys ($173.3{\pm}4.4$ cm vs. $169.7{\pm}3.2$ cm, P<0.01). Conclusion : There were significant differences in predicted adult heights between the BP and TW3 method in normal girls, precocious puberty girls, or constitutional growth delay boys. In precocious puberty and constitutional growth delay, the BP method might be preferred to predict adult height, but further studies on final adult height are needed.

We investigated the effect of fig fermented product(FFP) supplementation on growth performance, serum profile, carcass performance, meat performance and meat quality in 10 bulls of Korean cattle. Concentrates diet was supplemented with substrate fermented from fig fruit and leaves at 10% of the diet. The feed intake of FFP were slightly higher than the control, but the final weight showed no sifnificant difference between the two. Daily weight gain and feed intake were increased in FFP. The serum profile had no significant difference in the treatment. In carcass performance, the meat quantity grade of the treatment had no significant difference, but in meat quality grade the marbling score of FFP was significantly(P<0.05) increased therefore it showed a positive effect on meat quality grade. Also there was no significant(P<0.05) difference of meat cut performance in the treatment. Due to the proximate characteristics of longissimuss muscles the crude fat content of the FFP was significantly(P<0.05) increased. There was no significant difference(P<0.05) in physical characteristics ; pH level, meat color and heat loss of the treatment, but the shear force value and the cholesterol content of FFP significantly(P<0.05) decreased. Crude fat was increased(P<0.05) and cooking loss, shear force and cholesterol concentration were decreased. In fatty acids composition of the FFP, the linoleic acid from the longissimus increased significantly(P<0.05). In subcutaneous fat of longissimus of the FFP, C16:0(palmitic acid) significantly(P<0.05) decreased, but C18:1 significantly (P<0.05) increased. Therefore in FFP, the concentration of saturated fatty acid significantly decreased (P<0.05), but on the other hand the concentration of unsaturated fatty acids significantly (P<0.05) increased. In sensory evaluation of the FFP, the evaluation of odor increased slightly in a positive manner, also the appearance and the taste increased significantly(P<0.05). In conclusion when annexing additional fig fermented product to Hanwoo bulls, the carcass grade improves and the livestock production increases. Also the shear force, lower cholesterol, improved appearance and taste will open the doors to high quality meat production.

This study was conducted to determine the effect of cryoprotectants(sugar, sorbitol, polyphosphate) on quality properties of chicken breast surimi manufactured by pH adjustment(pH 11.0) during frozen storage. Final surimi was divided into experimental units to which the following treatments were randomly assigned: C(Alaska pollack surimi, two times washing, 4% sugar＋5% sorbitol＋0.3% polyphosphate additive); T1(chicken breast surimi, 0.3% polyphosphate additive); T2(chicken breast surimi, 5% sorbitol ＋0.3% polyphosphate additive); T3(chicken breast surimi, 4% sugar＋5% sorbitol＋0.3% polyphosphate additive). All amino acid contents of control were higher than those of all treatments, while T2 was higher in amino acid contents among the treatments. Shear force of all treatments were higher than that of control, but the breaking force, deformation and gel strength were lower. The TBARS(thiobarbituric acid reactive substances) and VBN(volatile basic nitrogen) values of all treatments were lower than those of control, The TBARS values of all treatments were increased with increased storage period. In sensory evaluation, the score of appearance, meat color and overall acceptability of control were higher than those of all treatments, but aroma, juiciness and tenderness were lower than those for all treatments.
