The present study was designed to examine fathers' awareness and practice of picture book reading with toddlers. The subjects were 221 fathers who have toddlers, and the data collected by questionnaires were analysed by mean and standard deviation, and frequency analysis. As a result, approximately 59% of fathers stated that it is essential to read to their children who are 12 month old or less, and 36% of fathers answered that they read books as much as their children wanted. The majority considered the emotional aspect of picture book reading as being significant. Also, nearly half (46%) of the fathers read books to their children 1-2 times per week, and 37% of them spent 6-10 minutes at a time reading books. While reading books, 60% of the fathers explained text and pictures to their children and a fourth of the fathers answered their children's questions. Also, while reading books, fathers tried to accept their toddlers' responses positively. However, they did not have much time to read books to their children and had little knowledge on how to read books to infants. Further research and education programs on picture book reading for fathers are needed.

The purpose of this study is to examine the relationship between the cell phone utilization and depression among the Korean elderly living alone using '2014 Korean National Survey on Older Adults. A total of 2,493 survey data of the elders living alone 65 years or more was included in the analysis. The degree of the cell phone utilization were categorized into (1) No cell phone, (2) Only phone calls, (3) Phone calls and text messages, and (4) Searching news and information through the internet surfing. The results showed that 81.5% elderly living alone had a cell phone. The 'no cell phone' group was 19.5% while 'information search' group was 3.5% among the elderly living alone and has more probability of depression than 'information search' group (OR=0.064, 95% CI=0.018-0.227), which indicates that as elders living alone utilize their cell phone more, the probability of the depression decreased. This result implies that elders living alone who utilize their cell phone more are engaged in social interaction more and this can lead to decrease in depression.

This study attempted to examine the loving pigeon culture practiced in traditional gardens and to illuminate the aspect of pigeons as a landscape animal material. In order to understand the culture of enjoying old garden through pigeons, the contents were analyzed for the translated version of the old literatures and paintings. Pigeons have been used as Jeonseo-gu(傳書鳩) and also for medicinal purposes and food. Pigeons have various symbolic meanings such as abundance, hospitality, and longevity. From the Goryeo Dynasty to the early Joseon Dynasty, pigeons were raised in the palace and private garden. In the late Joseon Dynasty, temporary trend of ornamental pigeon culture occurred. Pigeons were synesthesia materials that enriched the forest. Various beautiful pigeons created a variable landscape of the primeval forest as a moving landscape material. The bell sounds that appear differently depending on the pigeon's movement led to a rich auditory experience of the landscape. The pigeon house was an ornamental element that enriched the old garden along with the pigeon. The owners of garden were involved in gardening through the act of buying a pigeon house and placing it in the garden or making a pigeon house themselves. In addition, the writers planted plum trees, peach trees, apricot trees, and hawthorn trees as a symbol of spring and a source of food for pigeons, and expressed them in poems and paintings. This study has a limitation in that the translation of the old text was used as an analysis data. The follow-up studies on specific cases of raising pigeons in the old garden, in modern and contemporary landscape spaces are urged.

The development of information and communication technology and the improvement of the development and dissemination of smart devices have caused changes in the form of tourism, and the concept of smart tourism has since emerged. In this regard, researches related to smart tourism has been conducted in various fields such as policy implementation and surveys, but there is a lack of research on application reviews. This study collects Trip Advisor application review data in the Google Play Store to identify usage of the application and user satisfaction through Latent Dirichlet Allocation (LDA) topic modeling. The analysis results in four topics, two of which are positive and the other two are negative. We found that users were satisfied with the application's recommendation system, but were dissatisfied when the filters they set during search were not applied or that reviews were not published after updates of the application. We suggest more categories can be added to the application to provide users with different experiences. In addition, it is expected that user satisfaction can be improved by identifying problems within the application, including the filter function, and checking the application environment and resolving the error occurring during the application usage.
