The real-time monitoring about the activity of the human provides useful information about the activity quantity and ability. The present study implemented a small-size and low-power acceleration monitoring system for convenient monitoring of activity quantity and recognition of emergent situations such as falling during daily life. For the wireless transmission of acceleration sensor signal, we developed a wireless transmission system based on a wireless sensor network. In addition, we developed a program for storing and monitoring wirelessly transmitted signals on PC in real-time. The performance of the implemented system was evaluated by assessing the output characteristic of the system according to the change of posture, and parameters and acontext recognition algorithm were developed in order to monitor activity volume during daily life and to recognize emergent situations such as falling. In particular, recognition error in the sudden change of acceleration was minimized by the application of a falling correction algorithm

본 연구는 거주시설에서 생활하는 성인 지적장애인들의 일상생활을 살펴보고자 한 것이다. 이를 위해 24시간을 관찰 기록하는 생활시간조사방법을 활용하여 거주시설 지적장애인의 일상생활활동과 그 안에서 나타나는 상호작용을 분석하였다. 생활시간연구방법 중에서는 시간수지연구방법 중 '활동의 빈도'와 생활시간 중 '생활'에 초점을 맞추는 방법을 활용하여 내용 분석하였다. 거주시설 지적장애인의 일상생활 분석은 전 국민을 대상으로 한 생활시간조사 행동분류표(2004)를 기준으로 하여, 거주시설 일상생활의 특성을 살펴보았다. 상호작용 분석은 Flanders(1963)의 언어 상호작용분석모형을 기초로, 지적장애인과 생활재활교사의 상호작용 정도, 유형 등을 제시하였다. 이 연구는 국내 최초로 거주시설장애인의 일상생활을 있는 그대로 조명하여 그들의 일상에 대한 이해를 심층적으로 구축하고, 이용자와 생활재활교사의 상호작용을 분석한 점, 생활시간조사방법을 적용한 점 등에 그 의의가 있으며, 향후 관련 연구의 중요한 기초 자료가 될 것으로 본다.

Purpose: The purpose of this study was to examine the effects of a daily life-based physical activity enhancement program performed by middle-aged women at risk for cardiovascular disease. Methods: This study used a randomized control group pretest-posttest design. Middle-aged women aged 45 to 64 were recruited from two outpatient cardiology departments, and randomly assigned to an experimental group (n=28) and a control group (n=30). For the experimental group, after providing one-on-one counseling and education, we provided customized text messages to motivate them in daily life. To monitor the practice of physical activity, they also used an exercise diary and mobile pedometer for 12 weeks. Subjects' physical activities (MET-min/week) were measured using the International Physical Activity Questionnaire (IPAQ). Their physiological data were obtained by blood tests using a portable analyzer, and the data were analyzed using the SPSS 21.0/WIN program. Results: There were significant differences in exercise self-efficacy, health behavior, IPAQ score, body fat, body muscle, and fasting blood sugar between the two groups. However, there were no significant differences in total cholesterol, hemoglobin A1c, high-density lipoprotein cholesterol, and waist-to-hip ratio. Conclusion: Strengthening physical activity in daily life without being limited by cost burden and time and space constraints. Therefore, it is essential to motivate middle-aged women at risk for cardiovascular disease to practice activities that are easily performed in their daily lives.

Purpose: The purpose of this study is to identify the relationship between perceived smartphone addiction and physical and mental health among female college students. Methods: Data were collected using a questionnaire to measure perceived smartphone addiction and physical and mental health of 314 female students attending a college located in D city from April 9 to May, 31, 2019. The collected data were analyzed using descriptive statistics, 𝑥² test, t-test and stepwise multiple regression with SPSS 18. Results: The respondents were classified into two groups, the perceived smartphone addiction group (29.3%) and the perceived smartphone non-addiction group (70.7%). Perceived smartphone addiction was significantly different according to daily smartphone usage time (p<.001), smartphone usage fee (p=.005), most satisfying thing about using smartphones (p=.006) and importance of smartphones in daily life (p<.001). The perceived smartphone addiction group had more physical health problems (p=.001) and more mental health problems (p<.001). The factors affecting physical health were perceived smartphone addiction and importance of smartphones in daily life, with 62% of explanatory power (F=10.15, p<.001). As for mental health, the affecting factors were also perceived smartphone addiction and importance of smartphones in daily life, with 87% of explanatory power (F=14.52, p<.001). Conclusion: It is important to raise awareness of smartphone addiction including its negative impact on physical and mental health, reduce smartphone usage time, and build offline social relationships.

본 연구에서는 그동안 국내 지리학에서 상대적으로 소홀히 다루었던 치유(healing)에 관한 지리적 접근을 검토하고, 심리상담카페의 운영자의 시선을 통해 일상적 삶에서의 치유의 공간의 의미에 대해 생각해 보고자 한다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 눈에 드러난 정신과, 심리상담센터 등과 같은 곳은 일종의 문화적 낙인(cultural stigma)의 공간으로 인식되지만, 심리상담카페의 경우에는 이와 같은 심리적 거부감 내지 거리감을 낮춤으로서 치유가 필요한 사람들이 쉽게 접근할 수 있는 곳으로 통하고 있다. 둘째, 현대인들에게 요구되는 치유란 짧은 시간이나마 현실에서 도피할 수 있는 것이라 볼 수 있는데, 이러한 점에 있어서 인스턴트식으로, 기대하지 않았던 공간에서의 치유 활동은 심리상담카페의 이용자들에게 특별한 경험으로 다가오며, 부담스럽지 않은 선에서 반복적이며, 지속적인 치유 경험이 가능한 곳이 된다. 셋째, 심리상담카페는 누구나 이용할 수 있는 열린 공간인 카페로 재탄생함으로서 우리의 일상적 삶에 더 깊숙이 침투할 수 있는 장점을 가진 공간으로 활용되고 있다.

Background and objective: This study was conducted on Forsythia velutina, a special plant, in Gyeongsangnam-do Arboretum under the Gyeongsangnam-do Forest Environment Research Institute, which is located in the southern part of Korea. Methods: The research aimed to analyze the flowering characteristics of the plant by calculating the optimal temperature and humidity according to the flowering time and flowering period for 8 years from 2010 to 2017 in order to provide basic data for bioclimate studies of endemic plants. Results: It was observed that the Forsythia velutina showed a life cycle from mid-March and to mid-November. Average growth period was 243 (± 6.5) days. In testing the reliability of a single variable according to the meteorological factors, the Cronbach's Alpha was 0.701, which indicates that the findings were relatively reliable. The average date of flowering was March 16 (SD = 5.8) and the average date on which blossoms fall was March 29 (SD = 5.2). A substantial difference in flowering period was observed from year to year 11 to 23 days, with an average of 16 days (± 4.7). The temperature and humidity in February to March, which affect the flowering, were 2.9-5.5℃, and 66.5-73.0%, respectively, and showed differences every year. Conclusion: The correlation between flowering time and meteorological factors was positive, and the highest daily temperature and average daily temperature had the highest significance. When establishing basic data on plant species for the conservation of endemic plants, the changes in life cycle events and weather conditions are identified. It is believed that it will be helpful in establishing a conservation strategy for the plant species in the future.

본 연구는 통근자를 생애주기별로 구분하여 하루 동안 발생하는 통행시간에 미치는 요인을 분석하였다. 본 연구에서 통행시간이란, 통행사슬(Trip chain)개념을 적용하여 통근자가 집에서 출발하여 귀가할 때까지 하루 동안 일어나는 활동을 위해 이동하는데 소요된 시간의 합을 의미한다. 통근자의 생애주기는 가구주의 연령, 가족구성원의 유형을 근거로 미혼청년기, 가족형성기, 자녀교육기, 자녀청년기, 자녀독립기, 노년기의 6단계로 구분하였다. 생애주기별 통행특성은 통행시간, 사이클 수, 스톱수를 볼 때 차이가 있는 것으로 나타났다. 콕스비례해저드 모델을 적용하여 통행시간에 영향을 미치는 요인을 분석한 결과, 일부요인들은 생애주기별 통행시간에 영향을 미치는 것으로 나타났다. 본 연구는 실증적인 연구로써 경기도를 대상으로 하였으며, 자료는 2010년 가구통행실태조사 자료를 이용하였다.

Heart related diseases mainly caused by heavy work load and increasing stress in human daily life. Therefore, researches on mobile healthcare monitoring for daily life has been carried out. Notably, wearable healthcare monitoring system which has least restriction has been tried to provide an emergency alert of abnormal heart rate. In this study, we developed chair type unconstrained BCG measurement system which able to perform continuous heart status monitoring at the office and daily life in the unconstrained way. Furthermore, adaptive threshold is used to detect the heart rate from BCG signals. The HRV(heart rate variability) is calculated from heart rate interval. ECG signal measured using conventional method and BCG signal measured using unconstraint system are carried out simultaneously for the purpose of performance evaluation. From the comparison result, BCG signal shows a similar heart beat characteristic as ECG signal. This proves the possibility of practical implementation of unconstraint healthcare monitoring system. In addition, medical examination like valsalva maneuver is performed to observe the changes in HRV due to stress. By performing valsalva maneuver, heart is said to be placed under an artificial physical stress condition. Under this artificial physical stress condition, the time and frequency domain of HRV parameters are evaluated.
