The purposes of this study were to investigate the intercorrelations among various motivational patterns and learning strategies and to examine the differences in motivation and strategy usage in terms of students' science achievement level, gender, and grade. A questionnaire on achievement goal, self-efficacy, self-concept of ability, expectancy, value, causal attributions, and learning strategies was administered to 360 junior high/high school students (178 males, 182 females). Students who adopted performance-oriented goal tended not to be task oriented. Task-oriented students had high levels of self-efficacy, high self-concept of ability, and expectancies for future performance in science. They also valued science and attributed thier failures to the lack of effort. However, performance-oriented students evaluated their ability negatively, did not value science, and attributed thier failures to uncontrollable causes. With respect to learning strategy, task-oriented students tended to use deep-level strategy, whereas performance-oriented students tended to use surface-level strategy and not to use deep-level strategy. High-achieving students, boys, and junior high school students were more task-oriented, evaluated their ability more positively, and valued science more than low-achieving students, girls, and high school students, respectively. High-achieving students and boys also used deep-level strategy more than each of their counterparts. However, no significant difference in learning strategy was found between junior high school students and high school students. Educational implications of these findings are discussed.

This quasi-experimental study was to explore the effects of back massage with Lavender essence oil on the stress response of the ICU nurses. Method: Twenty nurses were selected as an experimental group and twenty nurses were in the control group. Lavender essence oil mixed with Jojova carrier oil was used to massage the neck, shoulder, back, and low back. Massage was done three times a week for 20 minutes for 2 weeks by the massage therapist. The stress response was measured with a subjective stress score, Cortisol and IgA level in saliva. The cortisol level in saliva was analyzed by an radioimmunoassay before and after back massage. The level of IgA in saliva was analyzed by an immunoturbidimeter assay and subjective stress scores was measured by Visual Analogue Scale. The data was analyzed using SPSS 8.0 and the hypotheses were tested by ANCOVA and the Pearson coefficient correlation. Result: 1) Score of subjective stress decreased significantly after the use of back massage with Lavender essence oil. 2) Level of Cortisol in saliva did not change significantly after the use of back massage with Lavender essence oil. 3) Level of IgA in saliva increased significantly after the use of back massage with Lavender essence oil. 4) After the use of back massage with Lavender essence oil, there was significant negative correlation between subjective stress and level of IgA in saliva. Conclusion: Back massage with Lavender essence oil is an effective intervention to reduce the stress response in the ICU nurses.

The purposes of this study were to investigate the effects of drug use & the health-related habits(alcohol drinking, smoking and exercise) on the nutritional status of elderly. subjects were 362 free-living elderly aged over 65(male 131, female 231) in Chungbuk area. Interviews with questionaire on drug use, health-related habits, and nutrient intakes, anthropometric measurement and biochemical blood test were carried out from August to October in 1996. Energy intakes of the males who used drug were lower than those of males who did not use any drug, while energy intakes of the females who used drug were higher than those of females who did not. In biochemical indices, LDL-cholesterol level of the males who used drug was higher than that of males who did not have drug. serum triglycerides, VLDL-cholesterol and obesity degree(BMI & TS) of the females who used drug were higher than those of females who did not have drug. Alcohol drinking, smoking and exercise habits of the elderly who used drug had little effects on the nutrient intakes while those habits had considerable effects on biochemical indices and obesity degree. Among drug users, male drinkers showed higher triglycerides & HDL-cholesterol level, and female drinkers showed higher triglycerides and lower total cholesterol and LDL-cholesterol level, compared to non drinkers. Among female drug users, smokers showed lower body mass index(BMI) compared to non smokers. Males and females who had both drinking and smoking habits showed higher serum triglycerides and VLDL-cholesterol level. Especially females who had both drinking and smoking habits showed lower BMI & Tricep skinfold thickness compared to those who had netiher drinking nor smoking habits.

The 'Pharmacy and Therapeutic Committee' decided to restrict the use of vancomycin which was categorized into restricted antimicrobials, among general, reserved and restricted antimicrobials. The committee also established prescribing guidelines of vancomycin in Seoul National University Hospital, May, 1991. Especially, the restricted antimicrobials should be used after approval by infectious disease specialist physician. A retrospective drug use evaluation (DUE) on vancomycin has been conducted to compare with the previous vancomycin DUE study in 1990. 'Criteria for DUE on vancomycin' was modified from Am J Hosp Pharm. Total 65 charts of patients were retrospectively reviewed from July 1991 to June 1992 in Seoul National University Children's Hospital. The justification of use was improved from 56% to 75% comparing with the previous study. In analyzing process indicators, several criteria including body temperature monitoring, WBC monitoring and use of concomitant antibiotics were well documented, but serum creatinine monitoring, culture and sensitivity test and level monitoring were infrequently performed, while the accepted level has been improved. Accepted level for appropriate initial dosage and duration of therapy were decreased. In outcome analysis, blood culture after discontinuing the drug was relatively well documented compared with the previous study. As the results, the approval vancomycin use was shown to be effective and rational in antibiotic therapy. And it is suggested that the above findings should be communicated to the medical staff, and a active intervention, such as feedback control, also be necessary for rational drug use.

There are a number of studies about the impact of social games' social network. But because of conflicting results, the game's effect isn't ascertained. In this study, we defined that using social games makes increase the social capital with construal level theory. The survey results on construal level, social capital, game using time, etc, are used for the analysis of the correlation and interact. As a result, growing bridging social capital shows on the people who use high level of construal and more social game time use. This phenomenon did not appear in other online games, so that makes a social games' feature unique characteristic. And we discovered that high level construals is key point for defining the practical use of media.

Objective: This study aimed to investigate the trajectories of mobile phone use with reference to its purposes, and to examine the effects of gender and interpersonal factors on the same in early adolescents. Methods: Latent growth modeling was used with a sample of 2,378 early adolescents from Grade 4 to 8. Data from the Korean Children and Youth Panel Survey conducted by the National Youth Policy Institute were used. Results: In boys and girls, overtime, the level of mobile phone use for communicating with family decreased, while that for communicating with friends increased. Level of mobile phone use for entertainment increased across time in boys; however, in girls, it increased from Grade 4 to 6 and decreased thereafter, until Grade 8. Gender was associated with the changes of mobile phone use according to the purpose of the same. Positive parenting, negative parenting, relationships with peers, and relationships with teachers predicted changes in mobile phone use for communicating with friends. Conclusion: These findings suggest that the processes involved in the trajectories of mobile phone use in early adolescence operate differently based on the purposes of the same. Additionally, the present results show that interpersonal factors are highly associated with mobile phone use for communicating with friends.

Purpose: This secondary data analysis study was aimed at identifying the factors related to the patterns of alcohol use (normal alcohol use, hazardous alcohol use, and alcohol dependence) in the Korean adult. Methods: This study analyzed the cross-sectional data from 230,715 Korean adults aged 19 year and older who participated in the 2009 Korean Community Health Survey. Multinomial logistic regression was used to uncover associations between demographic, health related factors and the patterns of alcohol use. Results: The patterns of alcohol use was differentiated from the sociodemographic variables (residential area, gender, age, marital status, educational level, monthly income, and occupation) and with health related factors (smoking status, hours of sleep, body mass index, pain or discomfort, subjective health, stress level, liver disease, cardio/cerebro vascular disease, and depression). Hazardous alcohol use was lower in rural areas and lower among women, but higher among people who smoke, reported severe stress, and/or depression. Similarly, alcohol dependence was lower among women and among those in rural areas, and was more likely associated with those who smoke, have severe stress and depression. Conclusion: A number of factors are associated with patterns of drinking. Smoking, severe stress and depression seems to confound the problems of alcohol use. Additional research is needed to isolate those factors that are the most important influencing the use of alcohol.

Optimal level of sedation and analgesia is important for the comfort and safety of critically ill patients. However, suboptimal sedation is relatively common in the intensive care unit (ICU) and it could cause prolonged mechanical ventilation and ICU stay, also increase delirium and ICU acquired weakness and resultant decreased survival. Therefore, accurate assessment of the level of sedation and analgesia, maintaining adequate level of sedation, and daily evaluation of each patient and following adjustment could be important treatment strategy in critically ill patients. Recently, the strategy for sedation in the ICU is changing toward the direction of lowering sedation level or even "no sedation" with concurrent use of analgesics and the use of ultra short acting analgesics could be helpful in some patients. Clinicians should be aware of the importance of algorithmic approach including daily interruption of sedative and assessment of sedation level and especially in the patients under mechanical ventilation, organizational approaches such as the 'ABCDE' bundle could improve the management of critically ill patients.

The current research attempts to measure the level of the acceptance of the Blackboard System (BBS) during the Corona crisis, and whether this is one of the reasons for the low use of the BBS at Al-Jouf University. To achieve this, the technology accepting model in the time of crisis (TAMTC) has been proposed to measure the degree of acceptance by students, which was then applied to a random sample of 339 of such. The results show a high level of student acceptance, despite their lower use of the system. The research also highlights the importance of upgrading e-courses and that the discontinuation of exam disqualification of students is secondary to their poor course attendance.

Ultimately, this research will focus on the activity traits of future customers in the convergence age. To accomplish that, firstly, researcher develop measures for assessing the convergence level of digital devices and digital services. Next, this will investigate the behavioral traits of people who use specific devices or services on the internet or mobile networks. This study proposed five convergence measures each for devices and services. For digital devices, measures such as converged functions, accessibility to network, portability, immediate communicability, and expandibility of functions were utilized. For digital measures such as scope of users, newness, social network level, ease-of use on mobile networks, and expandibility of information were used. We believe that the research results can provide insights for those wishing to explore the convergence level of devices and services and those developing high-level converged devices and digital services.
