This study explored the conception of children as portrayed in a personal diary written the middle period of the Chosun Dynasty. The Yangalok is a daily record in which Moonkun Lee wrote how he brought up his grandson. The Yangalok is an important historical document, showing how people brought up their children and indicating their conception of childhood. Research questions included the definition of the period of childhood and a description of parent-child relationships. It was found that childhood was completed by age sixteen, the importance of the child as family member hinged on his position as an heir, and the parent-child relationship was defined by Chin(親), including qualities of both love and discipline.

Objectives : Hajae's Diary(荷齋日記) is a personal diary written by Gyu-Sik Ji(池圭植) between 1891 and 1911. He had a strong interest in medicine and maintained the belief that diseases could be cured by medicine. He recorded in significant detail the subject individuals, symptoms, name of prescription, price, the date of exchange and place of purchase in his diary. Methods : His study classifies the era during which Western medicine was introduced to the general public and became popularized in the late Chosun dynasty period based on articles related to medicine in Hajae's Diary. Results : It could be identified that, as of the Gabo Reform(甲午更張) in 1894, Western medicine was introduced into the traditional medicine life and, starting from the Eulsa Treaty(乙巳條約) of 1905, Western medicine became popularized. Conclusions : During the "traditional medicine period", traditional medicine was used for all medicinal activities. However, during the "Western medicine introduction period", Western medicine was used for only specific diseases. In the period during which Western medicine became popular, traditional medicine continued to be used. However, Western medicine was widely used for various diseases.

personal nitrogen dioxide(NO$_2$) exposures for 31 professional drivers were measured using passive sampler and time activity diary in Asan and Chunan area, and were estimated using time-weighted average model. Mean concentrations of driver’s indoor and outdoor were 24.7$\pm$10.7 ppb and 23.3$\pm$8.3 ppb, respectively with indoor/outdoor of 1.1. Mean personal NO$_2$ exposure was 30.3$\pm$9.7 ppb. Personal NO$_2$ exposures were strongly correlated with indoor car NO$_2$ levels ($R^2$=0.80) rather than residential indoor NO$_2$ level ($R^2$=0.55). and outdoor NO$_2$ level ($R^2$=0.50). The driver’s NO$_2$ exposure using LP-gas with 24.4$\pm$8.0 ppb were statistically different from those using diesel with 36.3$\pm$14.1 ppb(p<0.01). The effect of driver’s smoking for personal NO$_2$ exposure was not found. It was considered that the main NO$_2$in driver is transportation. Since drivers mostly spent their times in indoor and inside car, time-weighted average model could be used to estimated personal NO$_2$ exposure using time activity diary, Though we did not measure all microenvironments, the estimated personal NO$_2$ exposures with 26.9$\pm$10.2 ppb were statistically correlated with measured personal NO $_2$ exposures30.3$\pm$9.7 ppb ($R^2$=0.89). The mean and standard deviation of personal NO$_2$ exposure using Mote-Carlo simulation were 26.6$\pm$7.2 ppb.

The "AR Campus Diary" project innovates in the realm of art through integrating augmented reality (AR) with interactive storytelling, fostering personal and interpersonal development through artistic expression. This artistic endeavor metaphorically represents the growth and fruition of individual stories, facilitated by a series of progressive art activities that emphasize continual interaction between self and others. Set against the backdrop of a university campus, the project employs AR markers designed to unfold stories in phases through a dedicated application, allowing participants to experience and influence the narrative uniquely. Diverging from traditional film editing techniques, "AR Diary" offers viewers the autonomy to navigate through story segments of their choosing, marking a departure from conventional cinematic storytelling by leveraging marker-based plot progression. This project not only showcases the fusion of technology and art but also pioneers a participatory form of art education based on engagement and play.

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.

In this paper, we present a standard S/W solution for nursery administration. This S/W would substitute for classical nonscientific nursery management that has depended on personal experience and intuition. Especially, the suggest S/W based on its early model(Hwangkum-a-jang) is designed to operate on its daily diary writing. It means every statistical data and information for a sales can be calculated by self analyzing function just by keeping a diary.

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.
