The purpose of this study is to examine the quality characteristics of lamb stock by different salt contents in it. For this purpose, mechanical tests (color value, pH, sugar content, salinity, amino-acid content) and sensory evaluation (attribute difference test & acceptance) were conducted, showing the following results; Salinity and sugar increased significantly (p<0.01, p<0.001) with salt contents increased. The 0.1% salt addition group contained 32 kinds of free amino-acids, while 0.2% and 0.3% contained 34. 0.4% salt addition group turned out to contain 34 kinds of free amino-acid in it. The amount of the free amino-acid content was also the highest with 0.3% sample group, followed by 0.2%, 0.4%, and 0.1% sample group. In the test group, 9 kinds of essential amino-acid were discovered, and all samples contained histidine and arginine, which were essential in the growth of children. Among all samples, arginine appeared to be the highest in content. Each of the essential amino-acid content varied with statistical significance among the sample groups. In addition, 14 kinds of amino-acids other than the above mentioned were discovered, as well. The 0.3% salt addition group showed the highest 'after taste' value, and the differences among the sample groups were statistically significant(p<0.001). The acceptance test of the lamb stock showed that the flavor and mouth feel did not vary among the sample groups with statistical significance. The control group had the highest value for appearance, measuring scoring 4.32, and the sample group of 0.2% salt addition showed the lowest value of appearance, scoring 3.63. As for the preference on the taste, the highest value of 4.09 came from the 0.3% salt addition group. The differences between the sample groups were statistically significant. Finally, with regard to the overall quality, the 0.3% salt addition group had the highest value of 4.23 while the control group scored the lowest, 3.52. The differences among the samples were statistically significant. The overall result of the study indicated that the optimal rate of salt addition in making lamb stock was 0.3%.

Purpose: This study aimed to evaluate the disease severity of children suffering from gastroenteritis using different scales. The results are compared and subsequently classified on the basis of the type of virus causing the disease in order to investigate the differences in clinical characteristics and disease severity according to pathogen. Method: This study was conducted prospectively with patients under 5 years of age diagnosed with acute gastroenteritis and hospitalized at 9 medical institutions in 8 regions across the Republic of Korea. Disease severity was evaluated using the Vesikari Scale, the Clark Scale, and the modified Flores Scale. Fecal samples collected from patients were used to detect rotavirus and enteric adenovirus by enzyme immunoassay, and for RT-PCR of norovirus, astrovirus, and sapovirus. Results: There were a total of 214 patients with a male : female ratio of 1.58 : 1, of which 35 were under the age of 6 months (16.4%), 105 were aged 6-23 months (49.1%), and 74 were aged 24-59 months (34.5%). The rate of concordance between the Vesikari and Clark Scales was 0.521 (P<0.001) and, in severe cases, the Vesikari Scale was 60.7% and Clark Scale was 2.3%, indicating that the Clark Scale was stricter in the evaluation of severe cases. Conclusions: In children with gastroenteritis, there were differences in disease severity based on the scale used. Therefore, to achieve consistent results among researchers, either only a single scale or a measure of all scales should be used to determine disease severity.

Purpose: Golf is a popular sports activity after total knee arthroplasty in old age patients. We evaluated golf and implant loosening through the radiologic method. We also evaluated correlation of patterns of golf activity and clinical outcome to suggest guidelines to the patients. Materials and Methods: We carried out a retrospective case-control study of 80 patients (80 knees) who underwent TKR between 2005 and 2008, and followed up more than 3 years. We divided patients who played golf after TKR as a study group and who did not participate sports activities as a control group. We calculated the sum of width of radiolucent line in 7 sections around femoral component, 7 sections around tibial components and 5 sections in patella component using American Knee Society Roentgenographic Evaluation and Scoring system respectively. The inclusion criteria, was BMI (body mass index) was between 25 and $30kg/m^2$, and UCLA activity-level rating System score was between 5 and 8. We also got the information of patients' patterns of golf activities such as 1. the interval from surgery to return to golf activity. 2. the frequency of golf activities 3. using spike or cart. We obtained the information from patient's questionnaire and telephone interview. We compared with the VAS (visual analogue scale) respectively. And handicaps and driving distance was evaluated as well. Results: The study group's mean sum of radiologic score was 0.84 mm and 0.69 mm in control group. This is not statistically significant (p=0.22). Too early returning to golf (p=0.01) and left knee replacement (p<0.01) were statistically significant factors affecting clinical outcomes of golf activities after total knee arthroplasty. Conclusion: We concluded that golf activities after total knee arthroplasty is not correlated with radiographic loosening, and we need to give an explanation to the patients about increased pain when returing to golf too early and left side arthroplasties.

In most cases of HPAI (highly pathogenic avian influenza) outbreaks, stamping-out operations are initiated by officially designating the affected premise, which is subsequently followed by depopulation of infected flocks. The primary objective of this study was to develop an evaluation method that correlates the level of biosecurity and the risk of having an HPAI outbreak in domestic poultry farms. A total of eight farms were selected nationwide, including layer farms, broiler farms, and an animal welfare type farm. The biosecurity level of the chosen poultry farms was assessed based on a total scoring index of 183 divided into three categories, general management (51), quarantine management (106), and sanitation management (26). Conclusively, the five layer farms (JS, GE, CS, HS, OE), scored higher overall scores compared to the animal welfare farm (CH) and broiler farms (JG, LB). In terms of scoring, which adds up to a total of 183 points, most layer farms scored between 130 and 157, while the two broiler farms and the welfare farm scored 45, 75 and 70, respectively. Next, an independent HPAI risk assessment of the farms was carried out. Regarding the correlation between biosecurity levels and HPAI risks, in the farms that presented a higher overall score in terms of biosecurity and outweighed the risks of HPAI, they tended to earn more points in the quarantine management category. The results of this study suggest that a viable system for evaluating biosecurity levels can establish strong correlations with the risk of having HPAI.

Recently, there are many considerations and studies on biological effects of radiations in radiation workers, as well as in accidentally or therapeutically irradiated persons. The most practical and reliable method of dosimetry for radiation accidents is the scoring of gross chromosomal aberrations in human lymphocytes (Ydr) as a biological dosimetry. By the way, although usual doses of $^{131}I$ administered therapeutically for thyroid cancer are ranging from 100 mCi to 200 mCi, there are differences of absorbed doses and Ydr, ranging from 0.004 to 0.04, on equally administered $^{131}I$ due to variations in metabolic characteristics, stage of tumors and physical status of subjects. In this study, We exert to obtain the dose-response relationships of $^{131}I$, as a good guide to evaluating acute effects of accidental irradiations and radiation induced leukemia or solid tumor, by in vitro induction of chromosomal aberrations. we studied the relationship between radiation dose (D) and the frequency of chromosomal aberrations (Ydr) obserbed in peripheral lymphocytes that were irradiated in vitro with $^{131}I$ at doses ranging from 0.05 to 6.00 Gy. By scoring cells with unstable chromosomal aberrations (dicentric chromosomes and ring chromosomes) we obtained this linear-quadratic dose response equation Ydr=0.064351 $D^2$-0.13143 D+0.045684 This dose-response relationship may be useful for evaluating acute and chronic $^{131}I$ induced biological effects.

Background : Interstitial lung disease has various manifestations that are differentiated by their pathology, progress and treatment. However, all manifestations eventually progresses to pulmonary fibrosis. Recent studies have shown that apoptosis of pulmonary epithelial cells might be related to pulmonary fibrosis. The correlation of the apoptotic index with the clinical manifestations, pathological findings, HRCT findings and the response to treatment were examined. Materials and Methods : Twenty subjects (14 men, 16 women), who had been diagnosed with interstitial lung disease through an open lung biopsy, were enrolled in this study. The subtypes were one AIP, two NIP, eight BOOP, and seven UIP cases. The apoptotic index was scaled from 0-2 depending on the fraction of positive staining cells by TUNEL method. The clinical severity was assessed by a modification of a previously developed CRP scoring system. The pathologic scores were based on 4 components: fibrosis, cellularity, desquamation, and granulation. In the HRCT study, each lobe was scored by the radiologists on a scale for both fibrosis and ground-glass attenuation. The treatment response was assessed by an increase in more than 10% of the CRP score, and comparing the results 3 months before and after treatment. Results : The apoptotic index showed no correlation with the CRP and HRCT scoring system. The apoptotic index correlated with the pathologic elements including fibrosis, cellularity and the desquamation score (p<0.05). Of the 16 patients who received corticosteroid therapy, 9 patients (56.3%) responded to therapy. There was no correlation between the response to corticosteroid and the apoptotic index. In the case of patients with acute and subacute ILD, the apoptotic index showed a correlation with the cellularity, desquamation, and the total histological score (p<0.05). In the case of patients with chronic ILD, the apoptotic index correlated with the fibrosis and cellularity score (p<0.05). Conclusion : Apoptosis of the pulmonary epithelial cells is implicated in the pathogenesis of interstitial lung disease particularly on a pathological basis.

Purpose: To validate and introduce the technique of the arthroscopic repair for the treatment of the Subscapulris tendon tear. Materials and Methods: From April 2003 to April 2004, Arthroscopic repairs were performed in 8 patient with subscapularis tendon tear. The mean follow-up period was 11months. two cases involved only subscaplaris tendon tear. Four cases were associated small sized posterosuperir. rotator cuff tear and two cases were in large size. The type of subscapularis tendon showed upper portion full-thickness tear in 6 cases, partial-thickness tear localized at articular surface in 1 case, complete tear in 1 case. The results were analyzed by using subjective satisfaction, inferior movenent of superior displaced humeral head, Constant-Murley functional scoring Results: Constant-Murley scoring was improved from 55 point preoperatively to 75 point postoperatively following 11 months. Mean score was 71 point except 2 cases of large superoposterior rotator cuff tear, Most humeral heads were distaracted postoperatively. The subjective result for the 8 shoulders were very satisfying in 5 cases, satisfying in 1 case and dissatisfying in 2 cases. Therefore satisfactory results were noted in 6 cases (75%) of this overall treatment group. Conclusion: The arthroscopic repair for the subscapularis tendon tear is thought to be available method, which could reduce severe complications following the weakness of deltoid muscle and postoperative pain. Especially Partial Subscapularis tear not associated with superoposterior rotator cuff tear including PASTA lesion was the sutable indication of the Arthroscopic repair.

This study has been performed to analyze and consider the problems after 30 years in terms of landscape design competition process in Korea, so that it can provide the basic data, which can improve the future landscape design competition. We have used Delphi Investigation to carry out a survey that targets professionals and identifies problems. The results are summarized as follows. Firstly, the results of the analysis of Landscape Design Competition for institution theory and case studies showed that there is an issue from four perspectives which are 'method of design competition', 'guidelines for design competition', 'winner selection process', and 'design changes after winning' Secondly, the process by professional Delphi performed expert analysis, and agree with expert opinion. As a result, we derived the problems of a landscape design competition system with the 12 items. Third, in the 'design competition style', two items, the 'design competition style' and 'problem of design public offering period' had become a problem. Fourth, the 'Guidelines for design competition', 'non-hierarchical excess of the amount of instructions', 'directive determined the guidelines', and the 'provision of confusion' three items had also become a problem. Fifth, 'sex expert committee review selection process winning work', 'Problems of participation', 'examination scoring system experts lack', and 'non-landscaping' had become a problem. Sixth, 'The design of the original order' as much as possible 'design changes after the winning work' Four 'order to Comments to reduce the creativity of the design of the climate', 'original extension', 'contractor feedback of excess without the promise of frequent personnel changes', design period of the person in charge is reflected in excess item has become a problem. I considered that a continuous research on the improvement of the problems of the landscape design competition system based on the results must be performed.

This research was carried out to see that to what extent KSD reaction can be related to types of sociometric status, and it was carried out on the basis of an hypothesis that KSD reactions of elementary school students in high grades(4th, 5th, 6th grades) would vary according to gender and 5 types of sociometric status, For that purpose, sociometry which were developed by Ahn Iehwan(2007) and KSD, were implemented with students of 20 classes (5 classes of 4th grade, 5 classes of 5th grade and 10 classes of 6th grade) at an elementary school in A city. Number of students surveyed was 366 and it was not exactly the stratified cluster sampling method. To verify 3 hypotheses, independent samples t-test, one way ANOVA, discriminant analysis were made. As a result, there was statistically significant difference in action factor and characteristics factor among 3 factors of KSD reaction by gender, but there was not statistically significant difference in dynamics factor. The result of one way ANOVA showed there was statistically significant difference in characteristics factor and dynamics factor among female students, but there was not statistically significant difference in action factor. Therefore, it was understood that characteristics factor of KSD reaction was closely related to gender difference and types of sociometric status. From the result of this research, it was considered necessary to review KSD scoring system suggested by 田中志帆(2009). And lastly, it was observed that KSD reaction was not effective in evaluating sociometry, and a new approach to the projective drawing test was suggested as a supplementary method for sociometry.

The purpose of this study was to examine the reliability and validity of the observed behaviors of subjects who suffered from low back pain with spinal diseases, Thirty two low back pain patients admitted on the neurosurgical unit in an army hospital were compared with 30 normal controls belonged to an army unit, by means of matching the age, hight and weight. Observed pain behaviors were developed by the researcher on the bases of literature and patient observation. This tool consists of 18 behaviors seperated into two major groups : mutually exclusive and concomittent behaviors. The mutually exclusive behaviors included coding cathegories for 6. body motions assumed by the subjects during the observation session. These 6 standardized motions consisted of sitting from standing first, and serially tying down, reclining, sitting again, and then standing, 6 steps walking. Concomittent behaviors consisted of 12 observable patterns that can be observed systematically from the face, grimacing, bracing, rubbing, walking with arms fixed, support with hands on sitting or standing, guarded movement, limping, unbalaced weightbearing, stopped movement from tying position to sitting, sighing and graoning. Subjects were videotrecorded as they performed a 6-standardized sequence of motions, simultanously researcher measured the time spent performing each motion and step length. Patients were asked torate their subjective pain score on the 10 mm graphic rating scale ranging from 'no pain' to 'sever pain'. For scoring of the pain behaviors, two trained nursing officiers independently and simutanously viewwd each videorecording and checked subject 'pain behaviors at the observational item checklist. The result of the study are summarized as follows : 1. Reability of the observational tool was a=.845. 2. Spearman's rho and percentage agreement were p=.97 and 81.7 persent respectively, that indicate adequate interrater reability of this tool. 3. The sensitivity rate of the tool was .875 while specificity rate .866 for differentiating patient from the normal. 4. When difference in the objective pain indices between patient group and control were compared, there was significant difference of all indices, such as pain behavior(t=7.71, p=.0001). spent time performing motion(t=14.2, p=.0001), step length (t=-10.72, p=.0001). 5. There were differences in the objective indices the subjective pain subgroups (low, medium, high). Differences in the mean score of objective pain behavior (F=6.376. p=.005) and spent time for moyion(F=4.631, p=.018). But there were no significant differences in the step length among the subgroups(F=.667, p=.521). 6. Highly correlated pain behavior items wiyh subjective pain score were 'stopped movement from lying position to sitting', 'limping', 'support with hands on sitting or standing', 'bracing', 'guarding' and 'walking with arms fixed'. In summary, although some of rho behavior items such as sighing and groaning in this study could not be observed because of videotaped datd, the reliability and validity of the over all observation method were satifactory. Thus, the results of the present study demonstrate rye potetional utility of the tool in assessing objective pain complementing self-reported pain in low back pain patients.
