This study intends to provide implications about sluggish use of calculators in our case by analyzing the math textbook of U.S. Macmillan/McGraw-Hill along with the tendency of paying more attention to math class using technologies. From the results of analysis, this textbook deals with various methods over around 3.3% of all pages, using calculators across all grades from 1st to 6th grade. In particular, it offers guidance into three types such as 'Choose a Computation Method', 'You can also use a calculator.', and 'TECHNOLOGY LINK', while particularly it is impressive in the perspective of using calculators as one of calculation strategies. And case studies of usage in textbooks describe 8 different perspectives as an example-represent; solve problems or equations; develope or demonstrate conceptual understanding; analyze; compute or estimate; describe, explain or justify; choose appropriate calculation method; determine a calculated answer's reasonableness. Reflecting on the fact that we still use calculators in a passive way, there are considerable implications to us.

The 「Act on Special Cases concerning the Punishment of Crimes of Domestic Violence」 still has various problems in the legal system and enforcement process. Contrary to the original intention of the legislation, it is operated very passively in terms of state intervention and punishment of domestic violence actors in actual operation. Even if it is treated as a home protection case, if you look at the details of the protection disposition, there is a problem that the decision on the protection disposition is biased towards a specific type of protection disposition. In order to improve this, the need for cooperation and active intervention between state agencies is required. In addition, it is necessary to establish a legal basis for a request for personal protection by recognizing the status of a victim who reported domestic violence as a crime reporter. In addition, in order to secure the effectiveness of the protective disposition, it is necessary to strengthen sanctions for non-compliance or violations of the protective disposition.

This study attempted to analyze the relationship between school life satisfaction and acculturation of elementary students of north Korean refugees in Daegu and Gyeongbuk region. The socio-demographic characteristics of elementary students in Daegu and Gyeongbuk were different from in capital territory or other parts of Korea. The acculturation of students living in Daegu and Gyeongbuk was distinctive. The proportion of assimilation was slightly higher than that of integration. However, 42 percent of students belonging to separation and marginalization passively accepted south Korean culture, so that they would have a difficult time in adjusting to new culture. Students getting older and being used to school life strongly inclined to accept south Korean culture; while, students born in north Korea tended to resist acceptance of south Korean culture. Most students were satisfied with school life. The satisfaction level was high in the relationship with teachers and school environment; while, the satisfaction level in learning activity was relatively low. In the relationship between school satisfaction and types of acculturation, students actively accepting new culture were relatively highly satisfied with their school life. A standardized short-term education oriented program for north Korean adolescents refugees living in south Korea should be shifted into the long-term support policy reflected in class and attribute in terms of acculturation.

Various environmental parameters change and ecological succession often lead to decline of Pinus densiflora forest in Seoul. Due to decline of it, we proposed the ecological management for conserving and improving from decrease of its dominant area on there. We analysed the P. densiflora forest's classification and suggested its ecological management that based on relation to competition between dominant species in the upper tree layer, the presence of competitive species in shrub layer and vegetation management standard. The Pinus densiflora forest types has been classified 6 types by ecological characteristics. The results from categorized its types are following as; 1) Pinus densiflora pure forest type; edaphic climax Pinus densiflora forest(26.1%), Pinus densiflora pure forest(21.5%). 2) the forest of Pinus densiflora and other species that compete with each other type; Pinus densiflora-Quercus mongolica forest(28.0%), Pinus densiflora-Pinus rigida forest(13.1%), Pinus densiflora-Quercus acutissima(4.2%). We conclude that the results in these kind of 4 types; Pinus densiflora pure forest type where possible to maintain the forest by edaphic climax, human trampling damage, vegetation management(e.x. remove the competition species, shrub layers management etc.) are mainly need to negative management. Whereas, the others 4 types; Pinus densiflora and other species(Quercus variabilis, foreign species, naturalized species etc.) that compete with each other types are need to positive management such as manage the same niche competition species, shrub layers management, remove the foreign species, naturalized species etc.. In these kinds of ecological management are very necessary to maintain Pinus densiflora forest.

This study aims to track pedestrian behavior in urban linear tourist sites and to analyse their behavioral characteristics. For these purposes, this study has adopted the direct observation, a behavioral tracking methodology, and selected Chenggyecheon in Seoul as the study site, a representative site of urban regeneration. The main results of this study can be summarized as follows: the period of stay and movement distance of pedestrians in the study area are both short and most pedestrian activities, apart from walking, are of a passive nature, such as pitching pennies, reading signs, resting and the like. Spatial points of Chenggyecheon at which pedestrians have exhibited these behaviors during their stay are summarized as 30 points and classified into 3 types: landmarks, bridges and nodes. Further research that combines several tracking methods in terms of urban pedestrian behavior is needed.

Security Business Act of Korea is leaning toward the aspect of regulation, while it provides few provisions about vesting the authority, which causes problems such as legal loopholes to be raised in regard to the rules about authorizing the private security personnel to perform security affairs properly and defining the limit of power. So, it should be done to interpret the law in order to draw the legal basis of empowering as well as to set limits of the authority of security main agent, and Article 7, Section 1, of Security Business Act is the very provision that involves the legal basis. In the scope of 'Management Power', the statutory authority in the first clause of Article 7 of Security Business Act, the security personnel can use force for self-defense, defense of others and property, and prevention of crimes. In addition, the powers of interrogation, access control, and eviction notice are involved in its scope. The private security personnel as the occupation assistant can take precautions and if the infringement on the benefit and protection of the law is imminent or done, he or she can use force within the limits of the passive resistance and the means of defiance on the basis of 'Management Power'. The private security personnel, however, can exercise the force only if the necessary conditions of legal defense, emergency evacuation, and legitimate act of criminal law are fulfilled.

The purpose of this study is to examine work-life balance by analyzing time schedules of married couple. The 2014 Korea Time Use Survey dataset was used for the analysis. Finally, 6,262 time diaries of 3,131 households were included in the analysis. The study used sequence analysis in particular, by applying the Lesnard(2014)'s dynamic hamming matching (DHM) method, which is useful for the time diary analysis where timing is a key factor. This study explored daily schedules of each man and woman according to 9 types of couple-combined work-schedules, which had been already derived by cluster analysis. The daily schedules were identified according to the activities divided as labor, housework, sleep, self-management, active leisure, passive leisure, and others. Here, time allocation was analyzed through various graphs showing average time amount and modal states by time period. Based on the analysis, it summarized that "long working hours as a main factor of work-life imbalance", "gender inequality of time use", "non-standard hours work impairing quality of life and "poverty of leisure time"as characteristics of work-life imbalance. Finally this study discussed the social policy implications to support work-life balance.

The purpose of this study is to explore how school social workers recognize on the school violence of adolescents by using Q methodology. To this study, selected 31 of Q samples related school violence of adolescent by applying Q methodology and 33 of socials workers completed classification table, and three types were derived. The first type is named 'a type of improvement parents' concern with nonprofessional perception' because it has a significant part in bringing up children by parents to prevent school violence of adolescent and also has a negative perception, which is difficult to approach professional intervention. The second type is named 'a type of uncertainty of responsibility with passive perception' because there is an ambiguousness between responsibility and criteria through connection of official on the school violence. The third type is named 'a type of absence of responsibility with professional perception' because it is perceived absence of job roles to prevent school violence. This type showed school social workers, as a professionals of school violence of adolescents, wanted to intervene school violence but realistic intervention was difficult. From this study, it is considered subjective perception of school social workers on the school violence of adolescents will be affected on the change of adolescents in the future, and it is a significant way to use them as a basic data to prevent or remove school violence of adolescents in the school through conception and typology of them.

The purpose of this study was to suggest measures for improving training cooperation between industries and universities through employer engagement by analyzing the state of employer engagement in training. The current study investigated the state of employer engagement in training and factors that facilitate employer engagement in training. A survey was conducted with 230 human resource managers who worked for companies with more than 300 employees. The study results showed that employers perceived their engagement in training for their employees are consumers rather than strategic partners to plan educational service and make decisions in their communities. However, employers perceived that their engagement in training would be effective because their training engagement can result in positive direct and indirect business outcomes. Moreover, the implementation of training programs based on industry needs was revealed as a critical factor for promoting collaboration between industries and universities and leading to employer engagement. Based on the study results, several suggestions are presented for improving training cooperation between industries and universities through employer engagement.

In order to prepare for changes in future society, cross-curricular learning is emphasized, and the need to link cross-curricular learning topics and subjects is increasing. However, there are few studies on how to deal with cross-curricular learning in mathematics education. This study analyzed the contents and methods of cross-curricular learning topics in subject-specific curriculum and mathematics textbooks. As a result of the study, the curriculum can be categorized into four types according to the variety of cross-curricular learning topics applied and the presence or absence of a main cross-curricular learning topic, and the mathematics curriculum belongs to the type where some cross-curricular learning topics are dealt with passively and there is no main topic. On the other hand, the analysis of 10 math textbooks for grades 5 and 6 according to the 2015 revised curriculum showed that, unlike the curriculum, various cross-curricular learning topics were applied in the textbooks, mainly environment and sustainable development education, safety and health education, career education, character education, and economic and financial education. In addition, in mathematics textbooks, cross-curricular learning topics appeared in various types such as materials, questions, explanations, illustrations, and in many cases, they appeared mainly as materials or illustrations. Based on these findings, implications were explored and suggested on how to integrate and apply cross-curricular learning topics in mathematics.
