Today Human Personal Trainers are becoming very famous in this health conscious world. They teach user to achieve fitness goals in managed way. Due to their high fee and tight schedule they are unavailable to mass number of people. Another solution to this problem is to develop digital personal trainer portable instrument that may replace human personal trainers. We developed a portable digital exercise trainer device - BIOFIT that manages, monitors and records the user's physical status and workout during exercise session. It guides the user to exercise efficiently for specific fitness goal. It keeps the full exercise program i.e. exercises start date and time, duration, mode, control parameter, intensity in its memory which helps the user in managing his exercise. Exercise program can be downloaded from the internet. During exercise it continuously monitors the user's physiological parameters: heart rate, number of steps walked, and energy consumed. If these parameters do not range within prescribed target zone, the BIOFIT will alarm the user as a feedback to control exercise. The BIOFIT displays these parameters on graphic LCD. During exercise it continuously records the heart rate and number of steps walked every 10 seconds along with exercise date and time. This stored information can be used as treatment for the user by an exercise expert. Real-time ECG monitoring can be viewed wirelessly (RF Communication) on a remote PC.

Purpose: From the holistic environmental perspective, individual and environmental influences on low-income children's questionable development were identified and examined as to differences in the influences according to the child's developmental stage of infancy (age 0-35 months) or early childhood (age 36-71 months). Methods: This study was a cross-sectional comparative design using negative binominal regression analysis to identify predictors of questionable development separately for each developmental stage. The sample was comprised of 952 children (357 in infancy and 495 in early childhood) from low-income families in South Korea. Predictors included individual factors: child's age and gender; proximal environmental influences: family factors (family health conditions, primary caregiver, child-caregiver relationship, depression in primary caregiver) and institution factors (daycare enrollment, days per week in daycare); and distal environmental influences: income/resources factors (family income, personal resources and social resources); and community factors (perceived child-rearing environment). The outcome variable was questionable development. Results: Significant contributors to questionable development in the infancy group were age, family health conditions, and personal resources; in the early childhood group, significant contributors were gender, family health conditions, grandparent as a primary caregiver, child-caregiver relationships, daycare enrollment, and personal resources. Conclusion: Factors influencing children's questionable development may vary by developmental stage. It is important to consider differences in individual and environmental influences when developing targeted interventions to ensure that children attain their optimal developmental goals at each developmental stage. Understanding this may lead nursing professionals to design more effective preventive interventions for low-income children.

본 연구는 연령에 따른 정서경험과 사회적 목표에서의 변화를 통해 노년기 정서적 삶에 있어서 정서최적화 특성을 확인하고, 주관적 안녕감이 어떻게 변화, 유지되는지 알아보기 위해 실시되었다. 청년집단 238명(평균 연령 19-23세), 중년집단 495명(48-64세), 노년집단 283명(65-82세)으로 총 1,046명이 본 연구에 참가하였다. 연령 증가에 따른 정서 경험의 차이를 확인해 본 결과, 중년에서 노년에 이르는 시기에 정적 정서 경험은 차이가 없고 부적 정서 경험이 다소 증가하는 것으로 나타났다. 노년집단은 다른 연령집단에 비해 정서최적화 유지를 위해 슬픔이나 섭섭함과 같은 각성수준이 비교적 낮은 정서들을 더 빈번하게 경험하며 삶에 있어서 정서관련 목표가 정보관련 혹은 능력관련 목표에 비해 더 중요한 것으로 나타났다. 연령 증가에 따른 주관적 안녕감의 차이를 살펴본 결과, 유의미한 연령차는 확인되지 않았다. 노인들은 우리가 생각하는 것 보다 다양한 정서를 경험하며 정서최적화를 통해 주관적 안녕감을 유지하고 있다는 점을 확인했다. 성별에 따른 정서 경험을 살펴본 결과, 노년 여성 집단이 노년 남성 집단에 비해 부적 정서를 더 많이 경험하며, 특히 배우자가 없는 경우 부적 정서를 더 많이 경험하고 주관적 안녕감이 낮은 것으로 나타났다. 노년기 정서 경험과 사회적 목표에 따른 정서 최적화 특성이 노년기 적응과 주관적 안녕감 유지에 대해 갖는 의의에 대해 논의하였다.

This study was conducted to develop and apply a computer-based multimedia nutrition education program for preschoolers based on the Dick and Carey model of instructional design. The Dick and Carey model included 4 phases: analysis, design, development, and evaluation. The program's instructional goals, objectives, assessment instruments, content, examples, and practice questions with feedback were written in the design phase. To be familiar with the 5 food groups, 'Nutrition exploration' were programmed using Hyperstudio. 'Nutrition exploration' was designed as a five-session, interactive multimedia game, with each session taking about 5 minutes to complete. Nineteen preschoolers, aged 6, volunteered to participate formative evaluation. The effectiveness of the program was examined using a pre-post test design. Participants were recruited by personal contact at the individual preschool education center. The application was carried out during 4 weeks. The results showed that intervention participants significantly increased knowledge between pre-test and post-test. The results support using IMM (interactive multimedia) to disseminate nutrition education to the target population. This research provides the basis for continuing development of computer-based nutrition education materials.
