Purpose: This study was done to identify the effects of a health diary program on fall related outcomes the low-income elderly women. Methods: The study was carried out with a nonequivalent control group with pretest-posttest design. The study was composed of two groups, each made up of 24 subjects: experimental group and control group. The subjects were low-income women aged over 65 years with osteoarthritis and both the experimental and control groups were made up of subjects with the same age profiles. The independent variable was the health diary program, and the dependent variables were fall related outcomes (fear of falling, fall-efficacy, knowledge of fall) difficulty of performing activity, and mood state. The health diary program was performed for 50 minutes each session and twice a week for 8 weeks. Data were collected before the health diary program 10 weeks after the beginning of the program. Results: The experimental group showed significant differences in knowledge of fall, fear of falling, and mood state compared to the control group. However there was no significant differences in difficulty of performing activity and fall efficacy. Conclusion: The results of this study may be used as part of an education to prevent falls for low-income elderly women with osteoarthritis.

Daily energy expenditures (DEE) of 82 co-eds in a University were estimated simultaneously by use of calorie counter and 15-min check list diary for 3 days, including a weekend day. The results are summarized as follows. The mean values of DEE from 15-min check list diary and calorie counter were 1967kcal and 1649kcal, respectively. DEE obtained with 15-min check list diary seems to be consistent with the results made by others concerning DEE of college female in Korea, but DEE by calorie counter was lower than that. However, DEE by calorie counter show high correlations with anthropometric indices of subjects and DEE by 15-min check list diary. Therefore, DEE by 15-min check list diary was taken as standard and regression equation for predicting DEE of subjects were developed: DEE by 15-min check list diary =3.31186 + 1.18837 $\times$ DEE by calorie counter. This technique for measuring DEE permits us to have more accurate estimate of DEE and acceptable to the subjects. When the subjects classified as underweight, normal, overweight according to relative body weight(RBW), DEE and DEE per kg of body weight were significantly different from each other between three groups based on RBW. The frequency of 15-minute periods with a categorical value of 1 was significantly higher in overweight than underweight and normal groups and the frequency of a categorical value 3 was significantly lower in overweight than underweight group. From the results shown above, physical activity level of overweight group was lower than that of normal and underweight groups.

Most of the current administrative names and locations for the names of places in the Nanjung diary have since been confirmed. However, a disagreement ensued among translators or researchers over Anpyeon-do (Baleum-do) islet recorded in Admiral Yi Sun-Shin's diary. Anpyeon-do was first recorded in the diary on October 11, 1597. It is credited to be the location where Yi Sun-shin and Chosun Naval Fleet stayed when sailing along the Southwestern coast of the Korean Peninsula after the battle of Myeongnyang. However, Anpyeon-do's exact geographical location has never been accurately confirmed. To accurately locate the islet, this study compared the direction and position of geographical locations observed in the Anpeon-do site match to actual geographical positions and directions. In addition, the direction and position of the geographical locations observed in the newly explored islands and mountains were evaluated with regard to how they correspond to the actual Anpeon-do. As a result, we concluded that the real location of Anpyeon-do recorded in the Nanjung diary is the Maebong mountain in Anjwa-do.

The aim of this study is to find out the user's needs of a 3D hand gesture interface in the smart home environment. To find out the users' needs, we investigated which object the users want to use with a 3D hand gesture interface and why they want to use a 3D hand gesture interface. 3D hand gesture interfaces are studied to be applied to various devices in the smart environment. 3D hand gesture interfaces enable the users to control the smart environment with natural and intuitive hand gestures. With these advantages, finding out the user's needs of a 3D hand gesture interface would improve the user experience of a product. This study was conducted using a diary method to find out the user's needs with 20 participants. They wrote the needs of a 3D hand gesture interface during one week filling in the forms of a diary. The form of the diary is comprised of who, when, where, what and how to use a 3D hand gesture interface with each consisting of a usefulness score. A total of 322 data (209 normal data and 113 error data) were collected from users. There were some common objects which the users wanted to control with a 3D hand gesture interface and reasons why they want to use a 3D hand gesture interface. Among them, the users wanted to use a 3D hand gesture interface mostly to control the light, and to use a 3D hand gesture interface mostly to overcome hand restrictions. The results of this study would help develop effective and efficient studies of a 3D hand gesture interface giving valuable insights for the researchers and designers. In addition, this could be used for creating guidelines for 3D hand gesture interfaces.

This study aimed to examine the urban families and rural families in tenns of life styles on Saturday-with-no-school. The subjects were the 386 parents whose children were in the first or second grade in rural or urban area. The instruments of analysis were time diary method and parents' stress scale developed by Kim & Kang(l997). The main results were as follows: First, in comparison with urban children, rural children spent more time in viewing TV and playing computer but spend less time in sleeping. field trip and cleaning on Saturday-with-no-school. Second, the difference of child-rearing time between mothers and fathers was less marked in urban area than in rural area. Rural fathers spent more time in watching TV or playing computer, while rural mothers spent more time in feeding and bathing of their children, helping their children do homework, and total child-rearing. Third, unlike urban parents, rural parents ddid not have much parenting stress on Saturday-with-no-school. These results show that there is a need to focus on rural parents in the preparation for introduction of 5 days-school-week system.

The purpose of this study was the development of traditional food recipes from local food contents related to the historical and cultural heritage in the representative long-lived area Damyang. The information on digging 'story' was collected through the region's representative local native journal, searching for related websites, analyzing old literatures, and interviewing traditional household; 'telling', the part of conveyance, was organized by reviewing the literatures, including historical condition, regional food materials, cuisine, region symbolism, etc. After nutritional analysis, the prepared, balanced, and healthy Korean food dishes using the traditional food contents were displayed. In Damyang, the story was extracted from Heuichoon Ryu (柳希春, 1543-1577) - figura of Damyang - and his collection, 'Miam's diary', and described about native food. The traditional history of many foods that were used mainly as rewarding during one's trouble, showing good faith, and delivering gratitude is recorded in Miam diary. A little effort has been made to express the classical scholar's clean and neat dining table which was the mixed Damyang's clean image and nobleman's straight integrity in the middle of the Choson Dynasty. Nutrition fact of 'Miam's table' was based on the Daily Reference Values of Koreans aged 65 or older.

A hierarchical linear model(HLM) provides advantages over existing traditional statistical methods (e.g., ordinary least squares regression, repeated measures analysis of variance, etc.) for analyzing multilevel/longitudinal data or diary methods. HLM can gauge a more precise estimation of lower-level effects within higher-level units, as well as describe each individual's growth trajectory across time with improved estimation. This article 1) provides scholars who study children and families with an overview of HLM (i.e., statistical assumptions, advantages/disadvantages, etc.), 2) provides an empirical study to illustrate the application of HLM, and 3) discusses the application of HLM to the study of children and families. In addition, this article provided useful information on available articles and websites to enhance the reader's understanding of HLM.

유선 인터넷에서 인스턴트 메신저는 간단한 질문/확인, 만남이나 작업 조정, 사회적인 친교 등을 위해 광범위하게 활용되고 있다. 이를 무선으로 확장하기 위하여 MSN, Yahoo, AIM, ICQ, 버디버디, 네이트온 등이 모바일용 메신저를 내놓고 있다. 특히 한국 10대의 경우 SMS를 실시간 대화에 가깝게 (짧고 빈번하게) 사용하고 있기 때문에 무선 메신저는 큰 호응이 있으리라 예상하였다. 그러나 네이트온 모바일 메신저의 경우, 2002년 출시된 이후 별다른 인기를 끌지 못하고 있다. 이에 저자들은 네이트온 사용자들의 사용행태를 분석하여 문제점을 파악하고, 일반 SMS 사용자들과 네이트온 사용자들의 무선 커뮤니케이션 사용행태를 1주일간의 Diary Study에 기초한 Contextual Inquiry (Intermittent)를 실시하여 사용률이 저조한 이유를 분석한 뒤, 퍼소나를 구성하여 무선 환경에 맞는 완전히 혁신적인 새로운 형태의 무선 메신저 사용자 인터페이스를 설계하였다. 메신저에 반드시 있는 사용자 등록이나 친구 추가 기능을 없애고 휴대전화 번호 기반으로 동작하며, 상태 정보(Presence)를 없애면서 상대방 상태에 따라 IM 혹은 SMS로 적절히 변환되어 전달되는 것이 주요 특징이다. 이를 사용자들을 통해 다시 검증해 본 결과 사용자들이 무척 쉽게 받아들이는 것을 발견하였다.

This study attempted to estimate the level of perceived lack of time in Korean society, to link it to time management and to identify the possible association that accounts for time shortage. I employed the gender perspective in order to reveal the dynamics and complexity of the perception of a lack of time in the population. The sample for the study was drawn from the 1999 and 2009 Korean time diary data collected by the Korean National Statistical Office. From the original data, I selected a sample of second shift families(men and women who are presently working and raising children) living in metropolitan areas(including Seoul and six major urban areas in Korea). The dependent variable was time pressure measured by a single-item question on a four-point likert scale. The results of the study showed that working mothers perceived a greater time shortage as compared to working fathers. The time use pattern showed change during the periods, indicating that people worked fewer hours in paid labor and enjoyed more leisure hours and personal care hours. However, on average, people seemed to have experienced a greater time lack in 2009 as compared to 1999. The results from the ordered logistic regression model revealed that even though there were similarities in the impact of relevant factors, men's perception of a lack of time was more closely linked with their work role and social status, while for women, this perception was influenced by work and family duties. This indicates that Korean working mothers and fathers are facing a double jeopardy of time shortage in terms of combining their work and family roles. As a result, the level of time pressure by gender is converging toward a "never enough" phase. These findings generated policy implications and detailed suggestions.
