The purpose of this study was to assess the physical activity and energy balance of weekdays and weekend in male high school students. Fifty healthy male high school students participated in this study. Anthropometric data were collected. Physical activity level (PAL) and energy intake for weekdays and weekend were calculated from a physical activity diary and food diary using the 24-hour recall method and interview. The resting metabolic rate (RMR) and estimated energy requirement (EER) were calculated from the prediction equations suggested in 2015 KDRIs. Total energy expenditure (TEE) was calculated by multiplying RMR by PAL. Mean age of subjects was $15.9{\pm}0.33years$. The daily pedometer counts were significantly higher in the weekdays (12,837 steps) than in weekend (6,661 steps) (P<0.001). The PAL of the weekdays ($1.63{\pm}0.17$) was significantly higher than that ($1.37{\pm}0.26$) of the weekend (P<0.001). PAL was significantly correlated with pedometer counts on the weekdays (r=0.495) and weekend (r=0.686). The total energy intakes ($2,847.2{\pm}681.5kcal$) and TEE ($3,046.3{\pm}437.3kcal$) of weekdays were significantly higher than those of the weekend. The results of this study would be useful to develop nutrition and exercise programs for male high school students on weekdays and weekend, respectively.

This study has two purposes. One is to know that it is Possible to use portfolio in the elementary math class. The other is to make a useful method for using portfolio. We got the following conclusion through the study. Portfolio gave students an opportunity that they could review their mathematical thinking. But it couldn't work very well for the low-level students. They didn't pay attention to the class. So, careful prepa-ration and training were necessary for the portfolio material. And the portfolio material must be prepared by appropriate contents. Teacher had to do math class by considering students ability. The math class could be much better for motivation, teaching-learning activity impro-vement and communication tool by using portfolio material. There are several imple-mentation processes in preparation, execution and utilization of the class. 1) Preparation: Teacher must decide if it is appropriate for portfolio by analyzing the course and textbook and set a final goal. And then teacher has to select an appropriate item and make a schedule for the class. The portfolio material must contain valuable things from which students learn mathematics and use in their life. The student level, utilization purpose and contents are considered when one prepares portfolio material. 2) Execution: Students are supposed to understand about the portfolio very well. It is important for them to get the opportunity for reviewing through math class diary, their opinion, friends opinion and teachers opinion. 3) Utilization: Parents review ameliorates the communication among teacher, student and parents about learning activity.

This study was conducted to understand the emotional and situational context where non-suicidal self-injury occurs in everyday life. Sixty adults(age 19-35) completed daily surveys assessing positive and negative emotions, stressful events, self-injury thoughts, and behaviors for two weeks. Using a total of 663 collected entries, we analyzed specific personal emotions and stressful events related to non-suicidal self-injurious thoughts and behaviors. As a result, high negative emotions, low positive emotions, and total stress event scores were significantly related to self-injury thoughts and behaviors. In the model in which both emotion and stress were inserted as predictors, the low level of positive emotion showed a significant related to non-suicidal self-injurious behavior. These results suggest that negative emotion management and overall positive emotion reinforcement are important in emotion regulation intervention for non-suicidal self-injurious patients. The meaning of this study is that it searched for risk factors of non-suicidal injury in everyday life using a short-term longitudinal method.

Purpose: The purpose of this study was to explore the perimenstrual discomforts and dietary intake levels among normal women. Method: A prospective and descriptive study examined 38 women aged 23 46years of age. The data collection period lasted from April 1 to June 30, 2003. The participants were asked to keep a diary recording perimenstrual symptoms and food intake for 50 days. Results: There was a significant difference in physical symptoms of perimenstrual discomforts (F=6.95. p=.001). but there was no significant difference in dietary intake level according to three different phases of a menstrual cycle. The significant dietary intake variables correlated to PMS included energy, protein, Vitamin E, Vitamin $B_2$, niacin, Vitamin $B_6$, folic acid, phosphorus, iron, and zinc. They were negatively related to perimenstrual discomforts. Conclusion: Balanced diet intake will be necessary for not only the perimenstrual discomforts but also the general health promotion of the entire population. The dietary and nutritional assessment should be done prior to nursing interventions, and nutritional counseling and education should be given based on individual differences. In a further study, the effects of dietary composition on specific symptoms will be replicated with a large sample, and development of a diet intervention program for perimenstrual discomforts is recommended.

Practice is essential in art and design. Through practice, artists gain tacit knowledge that is hard to acquire from conventional academic studies. This paper characterizes practice-led research in the study of fashion and textile design through the investigation of practice-led research theses in the UK. According to relevant literature, which includes four exemplary case studies, the following features can be drawn: First, the methodology is different in each case and the use of practice is unconventional. Second, the research is not always aimed at making products. Third, the structure follows an iterative process. Fourth, the ratios of theory and practice are different and various theories are used. Fifth, a personal journal or diary is used for reflection as a major aid to research. Lastly, the process should be recorded by a thorough academic method. Practice-led research can have unexpected outcomes in theory and practice. It can be a good option for fashion practice research to develop a better evaluation method and reduce the gap between subjectivity and objectivity.

This paper discusses about an empirical study to design a suitable experience monitoring and sampling system for mobile phone applications. We designed a new experience sampling method (ESM) research system iteratively. The research system is characterized by context-aware experience sampling, real-time data management, supporting data analyzing tools, and integrating ESM with ex-situ diary. From literature review, we derived initial design of the ESM research system. With the first system, we held the first experiment that evaluates three applications. From the experiment, we found that more functions are required, thus we improved the ESM system. Finally, we propose an ESM system design goal for the third iteration with experience of two experiments.
