This study examines features in using Japanese apricots that assume a leading place with a special symbolism among various species of trees adopted to traditional gardens from a landscaping view. Specific aspects of how Japanese apricots were adopted to traditional gardens are as follows. First, while Japanese apricots are used in modern landscape space, there traditionally were six types in use of Japanese apricots as Tammae(探梅) Jungmae(庭梅) Bunmae(盆梅) Byoungmae(甁梅) Chomae(造梅) and Mukmae(墨梅). Second, Japanese apricots planted in gardens[庭梅] were placed mainly in a front yard of Sarang-Chae(the men's part of a traditional house) took a central area because symbolism and ornamental values of Japanese apricots suited what classical scholars sought. Preferred planting sites at that time include south of the building, the yard of Sarang-Chae, space in front of windows and next to fences and waterside. Third, Japanese apricots in traditional gardens were planted in five ways; Dansik(單植) Daesik(對植) Gunsik(群植) Yeolsik(列植) Honsik(混植). Dansik was the most common way in planting Japanese apricots and Daesik intended to enhance orderedness and symbolism of space. Japanese apricots for appreciating in an open field took the form of Gunsik in general but Honsik was also used with species of special symbolism. This study offers an opportunity to grasp traditional planting methods of Japanese apricots based on understanding of cultural aspects of Japanese apricots by focusing on Japanese apricots, the representative traditional species of trees. Results of the study would help to recognize the need to newly understand Japanese apricots and be useful information to plant and use Japanese apricots in a traditional way.

The purpose of this study is to analyze the trend of changes in household labor among middle-aged generations who are facing dynamic changes in the middle of their life cycle. The research method is a literature study that examines and analyzes related data. Specifically, it aims to analyze the basic characteristics of middle-aged generations and trends in household labor, which are revealed through Time Use Survey, market trend reports, newspaper articles, and books. From the perspective of family resource management, housework is an unpaid activity performed by and for family members, and is an activity that can be replaced by purchasing goods or services from the market. This study focuses on the rapid growth of the home appliance market that replaces housework with the development of technology after industrialization, and how the change of technology affected the efficiency of housework. In addition, the composition and characteristics of middle-aged generations greatly changed according to changes in family structure, form, and family value. Examining the current state of housework and changing trends of middle-aged generations, which have different characteristics from previous generations, is significant in that it can predict future market trends and suggest implications for family policies that support the improvement of the quality of life of middle-aged generations.

The purpose of this study is to draw implication for scientific inquiry study by investigating level of understanding and actual state regarding the elementary school teachers' scientific inquiry. The survey was conducted toward 42 elementary school teachers who work at the D city by using questionnaire of Views About Scientific Inquiry. Actual state of understanding of scientific inquiry was investigated by categorized the responses to the level of understanding of the eight aspects of scientific inquiry in three levels (informed, mixed, naive) based on analysis criteria. And analyze whether the characteristic of the subjects affect to level of understanding about aspect of scientific inquiry. As a result of the analysis, the two aspects among the eights aspects of scientific inquiry; 'Inquiry procedures are guided by the question asked' and 'Research conclusions must be consistent with the data collected' were appeared to have high rates of informed level of understanding. In the remaining six perspectives, most of elementary school teachers had naive and mixed level of understanding, so informed level of understanding took a relatively low proportion. It implies that elementary school teachers who teach inquiry in the field have limit to understand about scientific inquiry. These results indicated that experiences that have taught students and science related training courses that open sofar have a little influence to increase comprehension about scientific inquiry. Therefore, it is required to reinforce the teachers' understanding about scientific inquiry and to formulate different form of plan unlike existing way of teaching for teaching scientific inquiry.

This study takes a close look at the recent success of independent documentaries to find its implications and a way to invigorate Korean documentary ecosystems. To this aim, this study performed in-depth interviews with independent documentary film makers and television documentary directors. Also, it analyzed the case of POV (Point Of View), which is television's longest-running showcase for independent documentary films in the USA. The results display that independent documentaries convey competitive edge of contents and expansion of distribution and funding through film industry systems, based on the producer systems, global distribution networks of overseas pitching and film festivals, marketing and audience strategy of film industry. Although this shows its molding of documentary industry ecosystems, there are great needs for various platforms other than film industrial outlet in order to make an advancement of the ecosystems under the digital environment. POV works on the basis of 'open sourcing' form when collaborating with independent film makers. Independent documentaries picked up by POV are aired on PBS, streamed via its online service, and distributed through community screenings; this three-outlet strategy makes POV a unique platform and has a relevance and feasibility to apply for Korean documentary ecosystems. Therefore, this study suggests to create a platform adopting POV system hoping that more studies and efforts would come for various and novel platform building so to make more advanced and invigorated ecosystems of Korean documentary.

This study was conducted to investigate the factors influencing the contraceptive behavior of male and female university students. Data were collected after receiving the written consent of 238 university students in G city during the period from September 22 to November 23 in 2017. Data analysis was performed using the SPSS PASW 18.0 program. The results revealed that 56.7% of the subjects used contraceptives, and 23.9% used condoms. Male students were more exposed to sexual content than female students (t=6.02, p=0.000) and had an open sexual attitude (t=5.38, p=0.000). Female students showed high scores on subjective norms (t=-3.51 p=0.000) and acceptable and positive contraceptive attitudes (t=-4.21, p=0.000). Among factors influencing the contraceptive attitude of males, the subjective norm was 3.6%. Female students had a 25.5% influence on contraceptive attitude, contraception, sexual education frequency, and sexual content exposure. It is suggested that sexual education and sexual counseling programs be developed to form positive attitudes toward contraceptives through iterative research.

In school facilities, space is the basic framework. The structure and arrangement of space will provide the form and feel of school facilities. In order to become a high-quality school facility, it is necessary to focus on the educational, human and ecological aspects of the instructor and learner until the space is conceived, designed and completed. However, even when public education was introduced in the past, it did not become a school space considering this aspect. The school space, which focuses on efficiency and labor production, is a school space that reflects the characteristics of a factory-type school, which has been occupied by a large number until recently. Although efforts to improve the quality of school facilities have been attempted in recent years, there is also a need to pursue more active changes. Future-oriented and progressive school spaces include flexibility, connectivity, individualization, diversity(creativity). In other words, space should be flexible so that it can be used faithfully according to the educational situation, not the fixed and limited school space as in the past. In the future, the school space should be open and securely linked to the place where it is essential to complete community relations with the community. In addition, space should be flexible so that the school can meet the needs of each student as much as possible. And the school space should be transformed from the space design of the past fixed pattern to reflect the close relationship between spatial, psychological, physiological, and behavioral areas. When school space needs to shift away from the past and change in a new future-oriented direction, the remaining tasks should be presented with specific characteristics and content of the direction. And the function of the consignment should be handled by related research. Although the text of this study reveals the characteristics of future-oriented school space, more concrete and empirical research results should be presented by subsequent research at home and abroad. It is necessary to reduce trial and error in creating a future-oriented school space where both professors and learners can be satisfied by analyzing the common points and differences between the results of the study. In order to do this, it is necessary to make efforts to approach such research based on the participation of the subjects who teach and learn directly at the school site.

In this paper, I found the leadership core-value of the Sunbai(선배) a man of refined taste. I studied twelve Sunbai considered as a man of refined taste in this research. I focused on the aspect showing common worth among their various abilities and cultural contributions, a point of view of classifying them into one form called Sunbai a man of refined taste. As the core value is the basis of supporting the individual identity, so the leadership core-value is the source and philosophical base of displaying the leadership. Our Sunbai combining character and knowledge show common structure in their personal growth and showing the leadership. It is that they embodied the stage of cultivating themselves(修身, Self), considering the relation with others(齊家, Relation), leading the organization(治國, Team), and making efforts for and having influence on the community(平天下, Community) throughout their own life. I examined how to display the leadership in the four fields on a case by case basis and then constructed the leadership model of the Sunbai a man of refined taste by synthesizing them. As a result, I considered their leadership core-value as the intercommunication and named it 'Leadership of Muaesabang(無碍四方)'. Also, I confirmed that it is still very valuable in these days of aiming at the open society and the harmony of the diverse civilization.

Research on diagnosing and predicting the response of ecosystems caused by environmental changes such as artificial disturbance and climate change is emerging as the most important issue of biodiversity and ecosystem researches. This study aims to clean, standardize, and provide the results of National Ecosystem Survey which should be considered fundamentally in diagnosing and predicting ecosystem changes in the form of dataset. To refine and clean the dataset we developed a simple verification program based on the fifth National Ecosystem Survey Guideline and applied that program to the data from the second (1997~2005), third (2006~2013) and fourth (2014~2018) National Ecosystem Survey. Data quality control processes were implemented including (1) standardization of terminology, (2) similar data table integration, (3) unnecessary attribute and error elimination, (4) unification of different input items, (5) data arrangement in codes, and (6) code mapping for input items. These approaches and methods are the first attempt propose an option for ecological data standardization in Korea. The standardized dataset of National Ecosystem Survey in Korea will be easily accessible, reusable for both researchers and public. In addition, we expect it will contribute to the establishment of diverse environmental policies concerning environmental assessments, habitat conservation, prediction of endangered species distribution and ecological risks due to climate change. The dataset through this study is open freely online via EcoBank (nie-ecobank.kr) which is the first ecological information portal system in Korea developed by National Institute of Ecology.

In platoon driving, several autonomous vehicles communicate to exchange information with each other and drive in a single cluster. The platooning technology has various advantages such as increasing road traffic, reducing energy consumption and pollutant emission by driving in short distance between vehicles. However, the short distance makes it more difficult to cope with an emergency accident, and accordingly, it is difficult to ensure the safety of platoon driving, which must be secured. In particular, the unexpected situation, i.e., variability that may appear during driving can adversely affect the safety of platoon driving. Because such variability is difficult to predict and reproduce, preparing safety guards to prevent risks arising from variability is a challenging work. In this paper, we studied a simulation method to avoid the risk due to the variability that may occur while platoon driving. In order to simulate safe platoon driving, we develop diverse scenarios considering the variability, design and apply safety guards to handle the variability, and extends the detail functions of VENTOS, an open source platooning simulator. Based on the simulation results, we have confirmed that the risks caused form the variability can be removed, and safe platoon driving is possible. We believe that our simulation approach will contribute to research and development to ensure safety in platoon driving.

This study examined the position and the characteristics of Korean writing textbooks in the rationales for writing education. Also, it explored the activities of writing knowledge formation based on the rationales in order to further propose some suggestions for the development of writing textbooks afterward. For this, it chose four Korean writing textbooks and presented the analyzed results through the processes consisting of material gathering, open coding, deep coding, expression and presentation as ones for the text qualitative analysis. First, it researched how the rationales such as formalism, cognitivism, and social constructivism were applied to and manifested in those textbooks. Furthermore, it examined how the language activities in the textbooks were shown from the four dimensions such as the knowledge of language structure, the process knowledge, the context knowledge, and the content knowledge; in particular, it focused on the content knowledge. It found out the results as follows. The rationales in structuring the chapters were not consistent with inner structures and contents. All the four writing knowledges were applied to each textbook; however, the emphasis and the proportion were different in each textbook. Also, it pointed out the textbook which contains diverse activities to be able to help the learners form the content knowledge and this sort of textbook is more effective from the perspective of social constructivism. Based on those results, it discussed several points which can be considered in the development and the selection of Korean writing textbooks later.
