This study describes a canine lymphosarcoma with a rapid proliferation and recurrence. A 4-year-old, male, Shih Tzu dog was examined for acute swelling mass. The mass had been identified since 3 months ago and enlarged $10{\times}7$ cm and located in the right axillary region. The surgical removal was recommended when patient visited veterinarian and the operation was conducted. The removed tumor was $11{\times}8{\times}7$ cm and firm, lobulated and white cut surface. Routine screening laboratory test was assessed with blood and radiological analysis. The metastasis sign was not detected on thoracic and abdominal radiography. Blood test revealed decreased lymphocytes. After surgical removal of the mass, microscopic histopathological examination was performed to determine the final diagnosis. Histopathologically, the tumors are characterized by the same histological features, including the presence of neoplastic cellular populations, and lymphocytes infiltration in varying proportions. Also, DNA was extracted and PCR analysis was employed to analyze the origin of tumor cells. T-cell specific nucleic acid fragments were specifically amplified by PCR. On the basis of the laboratory results, the tumor was diagnosed with canine T-cell lymphosarcoma. On the basis of our knowledge, this is the first report of canine T-cell lymphosarcoma in a Shih Tzu dog.

During the pipe forming process, a steel plate undergoes inelastic behavior multiple times under a load condition repeating tension and compression in the circumferential direction. It derives local reduction or increase of yield strength within the thickness of steel pipes by the plastic hardening and Bauschinger effect. In this study, a combined hardening model is proposed to effectively predict variations of yield strength in the circumferential direction of API-X65 and X70 steel pipes with relatively low t/D ratio during the forming process, which is expected to experience accumulated plastic strain of 2~3%, the typical Lüder band range in a low-carbon steel. Cyclic tensile tests of API-X65 and X70 steels were performed, and the parameters of the proposed model for the steels were calibrated using the test results. Bending-flattening tests to simulate repeated tension and compression during pipe forming were followed for API-X65 and X70 steels, and the results were compared with those by the proposed model and Zou et al. (2016), in order to verify the process of material model calibration based on tension-compression cyclic test, and the accuracy of the proposed model. Finally, parametric analysis for the yield strength of the steel plate in the circumferential direction of UOE pipe was conducted to investigate the effects of t/D and expansion ratios after O-forming on the yield strength. The results confirmed that the model by Zou et al. (2016) underestimated the yield strength of steel pipe with relatively low t/D ratio, and the parametric analysis showed that the t/D and expansion ratio have a significant impact on the strength of steel pipe.

For the purpose of encouraging healthy eating habits, this study surveyed 282 male and female university students in Busan to investigate the relationships between dining-out activities, eating habits, and the frequency of fast food intake and obesity. To confirm this, SPSS statistical programme 14.0 has been used to carry out the frequency analysis, fact and reliability analysis, $x^2$-test, t-test and the correlation analysis. As a result, it has been found that there is a correlation under p<0.01 between obesity and the habit of frequently eating unhealthy food, and there is a correlation under p<0.01 between obesity and the habit of frequently fast foods. Meanwhile, there is a correlation under p<0.05 between obesity and regular eating habits. Therefore, it has been concluded that there is a correlation between the obesity and eating habits as well as the frequency of fast food intake among the university students.

Purpose: To evaluate statistical differences among three measurements of range of motion (ROM) with Rapael Smart Glove (RSG) group 1, 2 and manual goniometer group. To investigate reference value of the kinematic analysis for range of motion (ROM) of distal upper extremity with Rapael Smart Glove (RSG). Methods: Sixteen normal persons without limitation of motion (LOM) enrolled in the study. The study was performed at two separate times and by two investigators on 16 normal adults. We compared ROM with RSG for measuring joint angles. We compared degrees of forearm supination/pronation, wrist flexion/extension and radial deviation/ulnar deviation during ROM of 16 participants using RSG. After one week, degrees of each motion were measured in the same way by other investigator to evaluate the reliability. Results: Statistical differences among three groups were showed. Most results of paired t-test between two RSG groups were over 0.05 and exceptions are supination, extension, and finger %. Conclusion: Our findings demonstrate that ROM of normal persons obtained by kinematic analysis with RSG are not valid as normal reference value for distal upper extremity motion. But, the reliability of between two RSG groups was showed with paired t-test and Pearson's correlation except supination, extension and finger %.

Little is known about sexual autonomy in the light of human sexual health or sexual behavior. The purpose of this study was to increase understanding of sexual autonomy by developing a scale to measure sexual autonomy in college students. The measure was based on the perspective of human beings as having autonomy. A methodological developmental design was used. The study was done in three steps and included concept development through content analysis of relevant literature individual interviews using open-ended questions with 19 college students, item analysis of data from self report questionnaires for item to total correlation, content validity index by professionals and college students, and factor analysis with principal component analysis. Three groups participated in testing the measurement scale; Group A in 1998, a nationwide convenience sample of college students (n=1,163), Group B, college students in 1999 (n=233), and Group C, college students in 2000 who responded to the measurement scale before and after a sex education program (n=216). A series of exploratory and confirmatory factor analyses were conducted to test validity. For analysis of the questionnaires, statistical methods including reliability (test-retest), item to total analysis, content validity, factor analysis for construct validity and t-test for mean difference according to gender, sexual coitus, previous sex education, and pre-post experiment sex education were used with SPSS 10.0. Results: 1. Two stable factors were extracted and these contributed 48.05% of the variance in the total score. All 13 items loaded above .40 on each factor. 2. Factor I with 10 items was named 'control' and factor II with 3 items and was named 'coping'. 3. Differences in sexual autonomy scores for college students according to their experience showed that there were significantly higher scores for sexual autonomy in the post sex education group(t=-10.841, p=.000), but there were no differences according to whether or not they had previous sex education. Female college students had higher sexual autonomy scores than male college students in A or B group (t=-5.933, p=.000/ t=-1.992, p=.048). 4. Cronbach's $\alpha$ was .8603 for the total 13 items with 1,632 college students, .8739 with 232 students, .8333$\sim$.7647 with pre-post sex education with 216 students. This measurement was found to have a high validity and reliability for measuring sexual autonomy in college students. Therefore, the author recommends that it be used to measure the effects of sex education. It is suggested that further study is needed to analyze the relationship between sexual autonomy and sexual behavior.

Media improvisation among lecturers in colleges is inevitable because of insufficient media resources for utilization. The study investigated media improvisation in the state -owned colleges of education in the South-West, Nigeria. The study is anchored on Media Richness Theory. Stratified sampling technique was adopted to select 812 lecturers. Media improvisation scale (r = .71) was used for data collection and T-test statistical method was adopted for data analysis. The result showed that there was no significant differences between media improvisation of Art/Social Science and Science lecturers (Crit - t = 1.96, Cal. t = 821, df = 278, p>.05) and that of lecturers in the School of Art/Social Sciences and Vocational/Technical Education (Crit. t = 1.96, Cal. t = .136, df = 276, p>.05). Significant difference did not exit between that of the Schools of Languages and Education (Crit. t = 1.96, Cal. t = 1.946, dif. = 288 p<.05) . It is recommended that media improvisation of lecturers in schools should be encouraged and improved upon.
