This study investigated the effect of teaching mathematical communication in mathematics learning. Cooperative learning, mathematics pin pals, and writing a mathematics diary were used to teach how to communicate mathematically. The experimental group was assigned to cooperate in class, to write a mathematics diary at the end of each class, and to exchange the mathematics pen pals once a week. The control group was taught by the traditional teaching method. The results were analyzed quantitatively and qualitatively. The learning achievement between the two groups was performed with pretests and posttests. And after this study, mathematics pen pals, video protocol and open-ended test were analyzed. The results of this study are the following: 1. There were little differences in learning achievement test between the group taught through communication and those not. And there were little differences in the results of achievement test between the two groups-high and low level classes.2. Cooperative learning, writing a mathematics diary and mathematics pen pals were effective as methods of teaching communication mathematically. The analysis of mathematics pen pals which is to investigate student's writing abilities showed that pen pal partners were improved in QCAI communication levels. There was a significant difference between the two groups in open-ended test. This means that communication learning has an effect on the tests for mathematical thought, reasoning, and creative thought. The analysis of video protocol showed that four students in a cooperative group were improved in their speaking and listening abilities.

Whilst Ecological momentary assessment (EMA) can provide important insights over time and across contexts among rotation workers whose work periods alternate with leave at home, it can also be challenging to implement in the resources and construction sectors. This review aimed to provide a summary of the methodological characteristics of EMA studies assessing health outcomes and related behaviors in rotation workers. Systematic searches in PubMed, Medline, EMBASE, CINAHL, PsycINFO, and Scopus were done to include 23 studies using EMA methods in assessing health-related outcomes and behaviors. EMA designs included daily diary: assessments once per day typically fixed at the end of day (47.8%), within day fixed interval time-based design: assessments on multiple times per day at certain times of day (17.4%) and combination of both designs (34.8%). Studies employed paper and pencil diaries (73.9%) and one or more electronic methods (60.9%): wrist-worn actigraphy device (52.2%) and online-based diaries (26.1%) for data collection. Most of the studies (91.3%) did not report prompting -EMAs by schedule alerts or compliance. Daily diary and within day fixed interval dairies designs are common, with the increasing use of electronic EMA delivery techniques. It is unclear how well participants adhere to assessment schedules, as these are inadequately reported. Researchers should report compliance-related information.

As a multidisciplinary study encompassing oceanography and history, we have attempted to reanalyze the course of a historical navel battle, Myungryang Naval Battle(September 16th, 1597 according to the lunar calendar) through hindcasting the paleo-tidal currents and -tides(PTC). Firstly, we conducted harmonic analysis using 6-month current data observed at Uldolmok and 1-year elevation data provided by Korea Ocean Research and Development Institute in order to understand their characteristics and to hindcast the PTC. Observation results show that Uldolmok, ~300m wide, relatively narrow channel, is characterized by a flood-dominant mixed mainly semidiurnal tidal regime induced by relatively-strong shallow water constituents, showing closely a standing wave type of tidal current. Further, we hindcasted PTC on the day of Myungryang Naval Battle. Our results were compared and discussed with results(time and speeds of maximum(flood and ebb) currents and high and low water times) of the previous studies estimated from different methods. Lastly, we reconstruct the course of the event of Myungryang Naval Battle recorded in the Admiral Sun-Sin Yi's War Diary(Nangjung Iigi in Korean) based on our hindcasting results.

Objectives : This study was designed to evaluate the effect of electroacupuncture at ciliao(BL32) on voiding pattern and uroflowmetry of patients with functional voiding disease. Methods Subjects were voluntarily recruited by newspaper·s and internet. All the subjects were confirmed as International Prostatism Symptom Score(IPSS), uroflowmetry, voiding diary, symptom. The acupuncture therapy was performed 3 times a week for 3 weeks by oriental medical doctor at hospital. Acupuncture points were BL32. The patient's symptoms were assessed before and after 3 weeks treatments by IPSS. Uroflowmetry for 5minutes and voiding diary for 48 hours was measured before and after 3 weeks treatments. Results : The results were as follows; 1. After 3 weeks compared to the pre-treatment, IPSS(QOL) scores were significantly unproved. 2. After 3 weeks compared to the pre-treatment, mean voiding volume, min voiding volume and mean voiding time on voiding daiary was significantly improved. 3. After 3 weeks compared to the pre-treatment, max flow velocity and mean flow velocity on uroflowmetry in spite of increase of voiding volume show a statistically significant difference. 4. Acupunctue had hardly some side effect compared to operation and medicines and was economical. Conclusion : This study suggests that acupuncture treatments can be applicable to improve symptoms in the patients with functional voiding disease. Further study on the acupuncture and other acupoints in the patients with functional voiding disease is recommended.

BACKGROUND/OBJECTIVES: Weight loss via a mobile application (App) or a paper-based diary (Paper) may confer favorable metabolic and anthropometric changes. SUBJECTS/METHODS: A randomized parallel trial was conducted among 57 adults whose body mass indices (BMIs) were 25 kg/m² or greater. Participants randomly assigned to either the App group (n = 30) or the Paper group (n = 27) were advised to record their foods and supplements through App or Paper during the 12-week intervention period. Relative changes of anthropometries and biomarker levels were compared between the 2 intervention groups. Untargeted metabolic profiling was identified to discriminate metabolic profiles. RESULTS: Out of the 57 participants, 54 participants completed the trial. Changes in body weight and BMI were not significantly different between the 2 groups (P = 0.11). However, body fat and low-density lipoprotein (LDL)-cholesterol levels increased in the App group but decreased in the Paper group, and the difference was statistically significant (P = 0.03 for body fat and 0.02 for LDL-cholesterol). In the metabolomics analysis, decreases in methylglyoxal and (S)-malate in pyruvate metabolism and phosphatidylcholine (lecithin) in linoleic acid metabolism from pre- to post-intervention were observed in the Paper group. CONCLUSIONS: In the 12-week randomized parallel trial of weight loss through a App or a Paper, we found no significant difference in change in BMI or weight between the App and Paper groups, but improvement in body fatness and LDL-cholesterol levels only in the Paper group under the circumstances with minimal contact by dietitians or health care providers.

Background: Low electrical impedance at acupoints is a familiar concept, and it has also been found that this increases with poor organ function. Kovich hypothesizes that organ states are communicated to their related acupoints in real time, and this experiment set out to test this. Methods: The electrical impedance at 4 digestion-related acupuncture points (acupoints) was recorded over a 14-hour period and a food diary was recorded. The readings were taken in 23 sessions, between which the participant continued his usual daily routine. Results: The impedance at all the monitored acupoints varied considerably throughout the day, and the peaks were aligned with periods of high stomach activity. Conclusion: Variations in stomach function produced corresponding variations in the impedance at key stomach-related acupoints. However, the experiment was limited in that samples were only taken at around 30-minute intervals, and further investigations are needed to explore this phenomenon in more detail.

The purpose of this study was to explore a typology of time use and analyze differences in life satisfaction according to the types of time use in the rural elderly. The research subjects were 1,000 people aged 65 years and over living in the rural areas of Korea. The data were collected through structured questionnaires and a time-use diary. The statistical methods used in the analysis included calculation of the mean and the standard deviation, ANOVA, Duncan's multiple range test, cluster analysis, and multiple regression analysis. The time use practices of the rural elderly were classified into three types: work-leisure balance, work-oriented, and leisure-oriented type. Life satisfaction of the rural elderly differed according to the type of time use. The work-oriented types showed the highest scores of life satisfaction, and leisure-oriented types showed the lowest.

Purpose: This study aimed to develop and evaluate a mobile application focusing on developmental support care for infants born prematurely. Methods: An application was developed using the analysis, design, development, implementation, and evaluation model. In the analysis phase, previous research was evaluated through big data text-mining and a literature review. In the design phase, the preliminary content of the application was designed, and the content validity and comprehension were verified. A hybrid application was developed and used by eight experts and ten users, who evaluated the layout of the mobile application and their satisfaction with it. Results: The content of the designed application comprised a diary, customized information, developmental play, and community. The mean scores for layout were 3.73±0.47 and 3.43±0.68 out of 4 points among the experts and users, respectively. Users' mean satisfaction score was 3.70±0.70 out of 5 points. Conclusion: The information provided by the mobile application was evaluated as consistent and systematic. The application was also found to be satisfactory by infants' parents. The mobile application developed through this study is expected to be effective in supporting the development of children born prematurely.
