  • An experiment was conducted to evaluate the effects of castration on growth performance, carcass characteristics, and meat quality of goat kids. Fourteen Boer-cross buck and wether goat kids (n = 7; initial body weight (BW) $38.0{\pm}0.35\;kg$ and $34.8{\pm}0.35\;kg$, for bucks and wethers, respectively) were grazed on annual Marshall ryegrass (Lolium multiflorum Lam.) for 56 days. Body weights were recorded after 4 h withdrawal from feed and water for two consecutive days, every 2 wk. After d 56, animals were harvested and hot carcass weight (HCW), cold carcass weight (CCW), dressing percent (DP), kidney and pelvic fat (KPF), longissimus muscle (LM) area, back fat (BF), and other carcass parameters were measured. Day 0 BW was used as a covariate for analyses. However, bucks were heavier than wethers at d 15 (p = 0.09), 42 (p = 0.001) and 56 (p = 0.001). Bucks had higher ADG (146 vs. 74 g/d; p = 0.001), HCW (21.2 vs. 18.8 kg; p = 0.06) and CCW (20.3 vs. 17.9 kg; p = 0.04) when compared with wether goats. Dressing percentage (51 vs. 47%; p = 0.06), KPF (0.44 vs. 0.16%; p = 0.02) and BF (0.41 vs. 0.21 cm; p = 0.05) were higher in wethers vs bucks, respectively; however, USDA live or carcass grades were similar. Longissimus muscle tissue from wethers and bucks were similar in darkness ($L^*$) and redness ($a^*$), but wethers had more (p = 0.02) yellow tint ($b^*$). Palmitic (C16:0), stearic (C18:0) and oleic (C18:1) acids were higher (p = 0.001) in muscle tissue from wethers compared to bucks. The saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA) contents of muscle tissue were lower (p = 0.001) for bucks with no difference in polyunsaturated fatty acids (PUFA). Longissimus muscle initial temperature was higher in bucks (p<0.04) and pH change post-mortem was similar for bucks and wethers. These results indicated that castration of young market goats reduced growth performance and produced carcasses with more fat and higher SFA.

  • Background: The objective of this research is the computed axial tomography (CT) imaging grading of radiation induced pneumonitis (RP) and its correlation with clinical and radiotherapeutic parameters. Materials and Methods: The chest CT films of 20 patients with non-small cell lung cancer who have undergone threedimensional conformal radiation therapy were reviewed. The proposed CT grading of RP is supported on solely radiological diagnosis criteria and distinguishes five grades. The manifestation of RP was also correlated with any positive pre-existing chronic obstructive pulmonary disease (COPD) history, smoking history, the FEV1 value, and the dosimetric variable V20. Results: The CT grading of RP was as follows: 3 patients (15%) presented with ground glass opacity (grade 1), 9 patients (45%) were classified as grade 2, 7 patients (35%) presented with focal consolidation, with or without elements of fibrosis (grade 3), and only one patient (5%) presented with opacity with accompanying atelectasis and loss of pulmonary volume (grade 4). Both univariate and multivariate analysis revealed as prognostic factors for the radiological grading of RP the reduction of FEV1 and the V20 (P=0.026 and P=0.003, respectively). There was also a significant (P<0.001) correlation of radiological grading of RP with FEV1 and V20 (spearman rho 0.92 and 0.93, respectively). Conclusions: The high correlation of the proposed radiological grading with the FEV1 and the V20 is giving a satisfactory clinical validity. Although the proposed grading scale seems relevant to clinical practice, further studies are needed for the confirmation of its validity and reliability.

  • Objective : The purpose of this study was to examine the relationship of the general characteristics of parents to their children's oral health care. The subjects in this study were 117 parents and their children who resided in rural communities in the region of K. Methods : A survey was conducted with the consent of the parents from July 1 to 30, 2010. As for the survey on the children, the children who were in the lower grades were interviewed, and the upper graders filled out the questionnaires in person. A frequency analysis was carried out to find out the general characteristics of the parents and children, and x2-test was utilized to grasp the links between the general characteristics of the parents and the children's oral health care. A SPSS WIN 12.0 program was employed to analyze all the collected data. The findings of the study were as follows: Result : 1. As a result of investigating the relationship of the occupation of the parents to the children's regular dental checkup, the 71.8 percent of the entire children didn't get a dental checkup on a regular basis. The biggest percentage of the children of the self-employed parents(100%) got a regular dental checkup, and 90.9 percent of the children of the government workers did that(p<.05). 2. As a result of checking the relationship of the occupation of the parents to the children's dental-caries experiences, 39.3 percent of the whole children had no such experiences. The largest percentage of the children of the company employees(51.9%) had dental-caries experiences(p<.05). 3. Concerning the links between the academic credential of the parents and the children's toothbrushing method, the biggest percentage of the children(40.2%) brushed their teeth up and down. The largest rate of the children whose parents were high-school graduates(41.5%) brushed their teeth in that way(p<.05). 4. Regarding the links between the toothbrushing time of the parents and the children's view, 43.6 percent found their parents to take good care of their teeth to make them clean. 60 percent whose parents brushed their teeth after having breakfast and dinner took the best view(p<.001). 5. As for the oral-health education experiences of the parents and a time for the children's change of toothbrushes, 29.1 percent changed their toothbrushes every two months, and 29.1 percent did that not on a regular basis but when the bristles of their toothbrushes got bent(p<.05). Conclusions : The above-mentioned findings suggest that in order to promote children's oral health in consideration of the characteristics of their parents, children should be urged to get a regular dental checkup, and the development of oral-health education programs in which parents and children can participate together is urgently required.

  • Objectives: This study is aimed to develop a Clinical Practice Guideline (CPG) on acupuncture treatment for the patients with post-stroke spasticity. Methods: Experts committee, consisting of stroke or methodology specialists, searched Medline, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and 19 Korean medicine journals. The search terms were selected to screen the randomized controlled trials (RCTs) or systematic reviews for the effectiveness of acupuncture on post-stroke spasticity, compared with placebo or conventional group. Levels of evidence and grades of recommendations were appraised based on Recommendations for Development of Clinical Practice Guideline in Korean Medicine. Results & Conclusions: One systematic review and 7 RCT were included to build the CPG. There was a strong evidence to support the effectiveness of electroacupuncture treatment for post-stroke spasticity. However, it did not show any sufficient evidence to treat the patients with post-stroke spasticity with the sole acupuncture. The moderate evidence was presented that over 3 times of the electroacupuncture treatments with 1-100 Hz frequency should be performed every week on the acupoints, such as LI11, LI10, TE5, LI4, ST36, GB34, ST40, or LR3, for 20-30 minutes. It was also suggested that the procedure should begin at the acute stage just after the vital signs of the patients are stabilized. Finally, there was a moderate evidence to support safety of acupuncture treatment for post-stroke spasticity.

  • In this study, literature review was done to examine and compare the current status and problems of different evaluation approaches toward permanent impairment in Korea. Alternatives and improvements in the current approaches in Korea were suggested. Series of cases were also examined to compare different approaches applied to the real cases, using 105 cases from a hospital data and another 207 cases from a insurance company data. The main findings of the literature review are as follows; 1. The current evaluation methods of permanent impairment in Korea are grouped into two categories, grading and rating. Gradings of impairments are expressly specified in 17 various statutes. 2. In Grading methods, the rigid system of 74 different grades has been adopted uniformally for the convenience of administration, which may not be, appropriate or valid from medical and scientifical aspect. 3. The adventage of McBride method is assessment of occupational disability rate. However the classified compensable occupations are only 280 and limited to manufacturing industries in 1960s'of U.S.A., which is not appropriate to current Korean circumstances. Especially, the job list does not include managerial officers or mental workers. 4. AMA Guides is the scientific and reasonable method for the assessment of physical impairment rate. However compensation and reparation of impairment case is difficult because this method cannot assess the disability rate according to occupation, age, etc. The results of cases comparative study are as follows: 5. The physical Impairment could be compared in 167 out of total 312 cases, and for the cases of complex impairment, McBride method underestimate physical impairment rate compared with AM A method. 6. When disability late was assessed, occupation was considered the compensation of only 85 cases, and age was used in only 21 cases. This was because occupation and age compensation in McBride method are unreasonable. 7. The most Ideal alternative is to assess physical impairment according to AMA method and then to develop a compensation method appropriate for the circumstances of Korea society.

  • This study aims to investigate smoking patterns in high school student and to give student smoker effective information. The sample of 250 male highschool students out of two different schools in Tae-Jon was questioned from July 10th to 15th. 1995. In analyzing these date. the statistics shows the realities by means of number of students. The results are summarized into 17 items as follows. Regarding the level of smoking. 140 students out of 250 admit that they have ever smoked. 52.1% of smoking students say that the motivation of beginning smoking is mainly curiosity. The survey shows that 22.9% of smoking students feel very good when smoking. It also shows that 30.0% of smoking students began smoking in the first grade of high school. With regard to the volume of smoking per day. 41.4% of smoking students smoke variably. 42.1% drink when smoking. 15.0% spend more than W 70.000 a month. About the question who knows the fact of their smoking. 51.5% answer that their friends know the fact of their smoking. In regard to the resaltionship between smoking and school per-formance. 18.2% of non smoking students make poor grades as compared with 40% of smoking students. 9.3% of smoking students say that they are satisfied with the school life. but 35.7% of them are not satisfied. Regarding the attitude to smoking teachers. 35% of smoking students state that they are affected by them. 69.3% of smoking students say that they will stop smoking. while the remaining 30.7% say that they will keep smoking. The reason of 63.9% to stop smoking is that smoking is bad for the health. The reason of 46. 5% to keep smoking is the acquired habit of smoking. 97.2% know the fact that the major element of cigarettes is nicotine and it is very harmful to the health. 40.8% recognize the harmful effect of smoking by TV and radio programs. 97.2% know that smoking could cause lung cancer. From the above results. I propose as follows We should make specific plan to keep smoking by simple curiosity from being developed into habitual smoking. We should teach them how harmful smoking is and make them stop smoking by themselves. It is very essential for family members and teachers to give continuous interest since childhood. As the teacher affect the students very much, they should give up smoking first. The incidence of smoking should be identified in each of the middle and high schools. smoking prohibition programs relevant to each school should be developed and implemented. The local community should ban cigarette vending machines. Cigarettes should not be sold to adolescents. By setting every place where adolescents gather including schools nonsmoking area. we should decrease their impulse to smoke. then smoking opportunities. and harmful effects to them caused by passive smoking.
