이 연구는 생활시간 연구를 위한 두 도구를 비교한다. 시간일지와 경험표집법, 이전의 연구들이 이 두 도구가 집합적 측정치에서 유사하다는 것을 보여 왔지만, 각 도구의 개별기록의 일치율을 비교한 연구는 없었다. 이 두 도구에 모두 응답한, 시카고 대학의 알프레드 슬로안 센터에서 행해진 500가족 스터디의 일부 표본을 통하여, 이 연구는 두 도구를 비교하고 상대적 장단점을 평가하였다. 연구결과는 시간일지가 보다 덜 편향된 행동시간 측정치를 제공하는 데 반해, 경험표집법이 일상생활에 대해 보다 구체화된 서술을 가능하게 함을 시사하고 있다. 후속연구를 위한 함의가 논의되었다.

Objective: In this paper, work time for the representative fruit crops are collected and analyzed using time-diary method, and the collected data were compared with the directly observed work time using GPS device. Background: There is no consistent conclusion which measurement method for work time is accurate. Most of the research results were collected from the environment other than rural area. Therefore, there is need to review reliability of the measurement methods for the agricultural work which are carried out for a long duration. Method: Top five crops (apple, pear, grape, sweet persimmon, and peach) were selected according to the number of farms and cultivation areas. We let fruit growers fill a work diary during one cropping period. A difference between the work-time that was recorded by the farmers and the direct observed worktime using GPS device were analyzed. Results: Average direct work time for the five fruit crops found to be 7.1% of the total work time. Conclusions and Applications: Reliability was secured by recording the daily work diary at each work stage while aware that direct observation is carried on. Data which are being collected by government institutions are obtained by the memories of the respondents. Therefore, it is needed to try the method adopted by this study in order to collect more accurate data.

본 논문에서는 자기 기입식 질문법에 의한 평가 노동시간과, 시간일지법에 의한 일기 노동시간 간에, 노동시간의 길이에 의한 체계적인 편차가 존재하는지 밝히고자 하였다. 노동시간의 길이의 측정 및 계산에 있어서, 자기 기입식 질문법은 그 측정의 용이성 등의 장점에 의해 주로 사용되어 온 반면, 시간일지법은 응답자의 행동들을 그 연속성 하에서 기록함으로써 보다 실제에 가까운 생활시간을 구할 수 있다는 장점에 의해 사용되어 왔다. 2004년도 생활시간조사 자료를 이용해 분석한 결과, 평가 노동시간을 기준으로 했을 때에는 평가 노동시간이 증가함에 따라 노동시간의 과대평가의 경향이 강해진다는 결론이 나오는 반면, 일기 노동시간을 기준으로 했을때에는 일기 노동시간이 증가함에 따라 노동시간의 과소평가의 경향이 강해진다는 결론이 나오는, 모순으로 보이는 결과가 나왔다. 공통된 조사에서 나온 자료임에도 불구하고 서로 정반대의 결과를 나타내는 이유는 평균에의 회귀 현상에 의해 무작위 오차가 서로 반대의 방향으로 작용 하기 때문이다. 따라서 평가 노동시간을 기준으로 한 결과만을 근거로 장시간 노동을 하는 사람 일수록 자신의 노동시간을 과대평가하는 경향이 강하다고 주장할 수는 없다. 즉, 노동시간의 증가에 따른 체계적인 편차는 존재하지 않는다는 사실이 확인되었으며, 따라서 이러한 편차의 존재를 근거로 자기 기입식 질문법에 의한 평가 노동시간을 통해 구해진 자료들의 신뢰성에 의문을 제기하는 것 역시 불가능하다.

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.

Objective: The aim of this study is to find and propose the behavioral characteristic of the elderly at their living space through diary study. Background: Recent development of technology and the emergence of various IT devices is contributing to active research in smart home, services which considers the behavior characteristics of the elderly are still unable to be provided. Method: This study performed self-diary study method with ten households aged over 65 that lived in smart home. Based on these data collected from the diary study, six behavior characteristics of elderly were drawn. Results: The elderly were aware of their cognitive and physical limitations and showed fear. They are difficult to adapt in the state of the art. Their activities to acquire information were limited and were against changes, preferring to maintain the old ways. Conclusion: The result of this study, findings of behavioral characteristics of the elderly reveal that most of them spend their time on personal maintenance, socializing and leisure activities. Therefore, smart home services related to these characteristics should be considered as a top priority. Application: The results of the behavior characteristics can be utilized for planning out future smart home services and thereby contributing to increase in convenience and satisfaction of the elderly.

This paper presents a method for generating an autonomous activity-based diary in the environment including a personal computer (PC). In order to record a user's various tasks in front of a PC, we consider the contextual information such as current time, opened programs, and user interactions. As one modality for the user interaction, a motion sensor was applied to recognize a user's hand gestures in case that the activity is conducted without interaction between the user and the PC. Moreover, we propose a temporal clustering method to recapitulate the sequential and meaningful activity in the stream of extracted PC usage logs. By combining those two processes, we summarize the user activities in the PC environment.

Assessment of information credibility is a ubiquitous human activity given that people constantly make decisions and selections based on the value of information in a variety of information seeking and use contexts. Today, people are increasingly engaging in diverse online activities beyond searching for and reading information, including activities such as creating, tagging and rating content, shopping, and listening to and watching multimedia content. The Web 2.0 environment presents new challenges for people because the burden of information evaluation is shifted from professional gatekeepers to individual information consumers. At the same time, however, it also provides unprecedented opportunities for people to use tools and features that help them to make informed credibility judgments by relying on other people's ratings and recommendations. This paper introduces fundamental notions and dimensions of credibility, and contends that credibility assessment can be best understood with respect to human information behavior because it encompasses both the level of effort people exert as well as the heuristics they employ to evaluate information. The paper reports on a survey study investigating people's credibility judgments with respect to online information, focusing on the constructs, heuristics, and interactions involved in people's credibility assessment processes within the context of their everyday life information activities. Using an online activity diary method, empirical data about people's online activities and their associated credibility assessments were collected at multiple points throughout the day for three days. The results indicate that distinct credibility assessment heuristics are emerging as people engage in diverse online activities involving more user-generated and multimedia content. A heuristic approach suggests that people apply mental shortcuts or rules of thumb in order to minimize the amount of cognitive effort and time required to make credibility judgments. The paper discusses why a heuristic approach is key to reaching a more comprehensive understanding of people's credibility assessments within the information-abundant online environment.

This study examined the time allocation pattern of farm wives. In particular it addressed i)the differences in extent of time spent in farming housework child care and leisure between on-farm and off-farm seasons ii)differences in the extent of time spent in such activities among farm wives and urban wives and iii) the determinants of time spent in such activities. To achieve these goals a system of time allocation equations based on household production theory was employed. On hundred and eight farm wives wiere selected in 1993 by the methods of judgement sampling and cluster sampling. Two major questions in the survey elicited sociodemographic information and time-use of farm wives using the time-diary method, The results indicate that farm wives different decisions about how to allocate their time to farming housework child care leisure during on-farm and off-farm seasons. In addition it was that farm wives are more likely to have dual responsibilities than are urban wives. Finally in the off-farm season education number of younger children and region were significant variables in explaining the time allocation decisions of farm wives. However only age was a significant factor in their time allocation decisions during the on-farm season. This leads one to conclude that time allocation is not a choice for farm wives in the on-farm season.
