  • A national animal health monitoring system(NAHMS) in Gyeongnam area was started from 1997 to develop statistically valid data for use in estimating disease frequencies in dairy cattle, and the associated costs. The objectives of this study were to : (1) discribe what was done to implement and maintain the system in Gyeongnam ; (2) present selected disease frequencies ; (3) discuss the epidemiological consideration of what was done and implications for the results obtained. Veterinary Medical Officers(VMOs-professors and graduate students from Gyeongsang National University, Faculty of Gyeongnam Livestock Promotion Institute, and Clinic veterinarians) served as data collectors. After training on current disease and management problems of dairy cattle, interview techniques, sampling methods, and data collection instruments, the VMOs participated in selection of the sample herds and data gathering. Forty of 167 dairy herds were selected randomly and the VMOs visited farms once a month for 12 months to collect data about management, disease, inventory, production, preventive treatment, financial and any other relevant data. Strict data quality control devices were used. Specific feed-back was developed for the producers and data collectors. Of the three age groups studied, cows had the greatest number of disease problems. The six disorders found most frequently were (from the highest to the lowest) breeding problems, clinical mastitis, birth problems, gastrointestinal problems. metabolic problems, and lameness. In young stock, respiratory, multiple system, breeding problems, and gastrointestinal problems were pre dominant, whereas in calves, gastrointestinal, respiratory, and integumental problems were major.

  • In order to study the effect of the 'General Science' course implemented under the 6th science curriculum, high school students' views about the relationship between science/technology and society and their perceptions of science classroom environment were investigated. Four classes (n = 211) were selected from those completed the 'Science I' course under the 5th science curriculum, and 4 another classes (n = 216) which took the 'General Science' course under the 6th science curriculum were selected. In order to compare students' views about the relationship between science /technology and society. 10 items were selected from the VOSTS (Views On Science-Technology-Society) while considering the 6th science curriculum and the 'General Science' textbooks, and administered at the end of the 'Science I' course and at the beginning and end of the 'General Science' course. In order to compare the perceptions of science classroom environment, the Perceptions of Science Classroom Environment Questionnaire, which was prepared from the Individualized Classroom Environment Questionnaire. the Science Laboratory Environment Inventory, and the Classroom Environment Scale. was also administered at the end of the 'Science I' course and the 'General Science' course. The results indicated that the mean VOSTS score of the 6th-curriculum group was lower than that of the 5th-curriculum group, although the difference was not statistically significant. The decrease in the VOSTS score of the 6th-curriculum group during the 'General Science' course was statistically significant. It was also found that unrealistic views such as 'technology is the application of science', and 'corporations should control science/technology' had been formed during the course. However, the 6th-curriculum group had more positive perceptions of science classroom environment. Educational implications are discussed.

  • Purpose: The purpose of this study was to investigate the influencing factors on externalized and internalized problem behaviors among high school students. Methods: The subjects for this study were 707 students in two high schools in K province. The data were collected during the period from October to November, 2014 by use of questionnaires. The instruments used were the Korean Youth Self-report, Daily Hassles Questionnaire, State-Trait Anger Expression Inventory, and Ego Resiliency Scale. The data were analyzed using SPSS. Results: Significant predictors to explain externalized problem behaviors comprised anger-out, anger-in, anger-control, relation with parents, daily stress, and religion. It was found that these factors explained 46% of externalized problem behavior. Ego resiliency, anger-in, daily stress, gender, relation with parent, and anger-out were significant predictors to explain internalized problem behaviors. It was found that these factors explained 45% of internalized problem behaviors. Conclusion: This study suggests that the influencing factors on problem behaviors differ from externalized and internalized problem behaviors. So these findings will provide the basic data to develop a program that is differentiated by problem behavior type.

  • Purpose: This study aimed to identify factors affecting the quality of life of the elderly people with chronic musculoskeletal pain. Methods: The data were collected from 307 older adults aged 65 years or older with chronic musculoskeletal pain, who visited senior welfare centers in two cities. We used self-rated questionnaires including NRS for pain, WHOQOL-BREF for quality of life, Pain Response Inventory for coping responses to pain, and MSPSS for social support. Stepwise multiple regression analysis were performed using SPSS/WIN 23.0 to identify factors affecting the study subjects' quality of life. Results: The regression model explained 43% of quality of life, which was statistically significant (F=34.11, p<.001). Educational level of high school (${\beta}=.13$, p=.006), pain (${\beta}=-.13$, p=.013), restriction of function (${\beta}=-.13$, p=.028), accommodative pain coping (${\beta}=.24$, p<.001), family support (${\beta}=.18$, p<.001), colleague's support (${\beta}=.25$, p<.001), and perceived health status (${\beta}=.25$, p<.001) were identified as influential factors on subjects' quality of life. Conclusion: Developing integrative interventions is necessary to improve accommodative pain coping skills and to engage family and colleague in support for positive perception of older adults' health status and management of symptoms.

  • Background: Despite muscle latency times and patterns were used as broad examination tools to diagnose disease and recovery, previous studies have not compared the dominant arm to the non-dominant arm in muscle latency time and muscle recruitment patterns during reaching and reach-to-grasp movements. Objects: The present study aimed to investigate dominant and non-dominant hand differences in muscle latency time and recruitment pattern during reaching and reach-to-grasp movements. In addition, by manipulating the speed of movement, we examined the effect of movement speed on neuromuscular control of both right and left hands. Methods: A total of 28 right-handed (measured by Edinburgh Handedness Inventory) healthy subjects were recruited. We recorded surface electromyography muscle latency time and muscle recruitment patterns of four upper extremity muscles (i.e., anterior deltoid, triceps brachii, flexor digitorum superficialis, and extensor digitorum) from each left and right arm. Mixed-effect linear regression was used to detect differences between hands, reaching and reach-to-grasp, and the fast and preferred speed conditions. Results: There were no significant differences in muscle latency time between dominant and non-dominant hands or reaching and reach-to-grasp tasks (p>.05). However, there was a significantly longer muscle latency time in the preferred speed condition than the fast speed condition on both reaching and reach-to-grasp tasks (p<.05). Conclusion: These findings showed similar muscle latency time and muscle activation patterns with respect to movement speeds and tasks. Our findings hope to provide normative muscle physiology data for both right and left hands, thus aiding the understanding of the abnormal movements from patients and to develop appropriate rehabilitation strategies specific to dominant and non-dominant hands.

  • Propose: To identify the effects of job stress for depression in clinical nurses. Method: The subjects were 304 clinical nurses in Busan Metropolitan City. Data was collected by questionnaire surveys using convenience sampling. The instruments used in this study were the short form of the Korean Occupational Stress Scale(KOSS-SF) and the Beck Depression Inventory-Korean Version Standard Ten(K-BDI STEN). Result: After adjusting potential confounders, we found that the group of 50~75% job stress score for interpersonal conflict was more likely to have depression than the group of less than 25%(OR=3.522, 95% CI 1.06~20.25). The group of equal or more than 75% job stress score for job insecurity was more likely to have depression than the groups of less than 25%(OR=9.413, 95% CI 4.00~71.03). The groups of equal or more than 75% and 50~ 75% job stress score for lack of reward was more likely to have depression than the group of less than 25%, respectively(OR=19.302, 95% CI 2.50~244.25; OR=38.201, 95% CI=6.25~344.45). Conclusion: To prevent depression in clinical nurses, we need to intervene job stress for insufficient job control, interpersonal conflict, job insecurity and lack of reward.

  • Objectives : This study investigated factors related to suicide in high school students and focused on perceived academic performance. Methods : We surveyed 293 grade 10 high-school students in Jeju and Gyeonggi provinces and gave them self-assessment questionnaires. To evaluate the suicide risk, the questionnaire included questions about suicidal thoughts, plans, threats, deliberate self-injury, and suicide attempts from the Scale for Suicide Ideation (SSI). Also, it included the Beck Depression Inventory (BDI), Beck Hopelessness Scale (BHS), Locus of Control Scale (LOC), Rosenberg's Self Esteem Scale (RSE) and Perceived Academic Performance (PAP) to identify factors related to suicide in high school students. Results : Depression, hopelessness, and low self-esteem were related with suicidal thoughts, plans, attempts, and severe suicidal ideation (SSI score${geq}$16). In the multivariate analysis, a low level of PAP (OR=3.796, 95%CI 1.280-11.257) was significantly associated with severe suicidal ideation (SSI score${geq}$16). Deliberate self-injury was most prevalent in failing the PAP group and also having a high level of PAP (OR=6.161, 95%CI 1.474-25.760). Conclusion : The authors found that the suicide risk of high school students is related to depression, hopelessness, low self-esteem and a low level of PAP. These results provide significant indicators in planning an adolescent suicide prevention program.
