Currently, the Republic of Korea is facing the problem of a decrease in military service resources due to the demographic cliff, and is pursuing military restructuring and changes in the military force structure in order to respond to this. In this situation, the Army is pushing forward the deployment of a drone-bot combat system that will lead the future battlefield. The battlefield of the future will be changed into an integrated battlefield concept that combines command and control, surveillance and reconnaissance, and precision strike. According to these changes, unmanned combat system, including dronebots, will be widely applied to combat situations that are high risk and difficult for humans to perform in actual combat. In this paper, as one of the countermeasures to these changes, autonomous behavior software with a BDI architecture-based decision-making system was developed. The autonomous behavior software applied a framework structure to improve applicability to multiple models. Its function was verified in a PC-based environment by assuming that the target UAV is a battalion-level surveillance and reconnaissance UAV.

This study has surveyed 379 social workers to recognize how much they believe their behaviors are ethical related to dual relationship and how many they have experienced dual relationships with their clients. In addition, we also examined if there were significant differences in social workers' beliefs and experiences according to their socio-demographic characteristics and organizational properties. To accomplish this purpose, we conducted frequency analysis, single sample t-test and one-way analysis of variance focusing on sexual, bartering and private relationships. Respondents tend to have a little permissive attitude about dual relationships while they little experienced of them. Social workers's beliefs and experiences are different depending on gender, education level, work experience, position, training experience of ethics and service target. From these results, it suggested that code of ethics for social workers and the curriculum of social work ethics should be revised reflecting on present field situation and inspiring ethical sensitivity.

According to the 2019-2020 social media usage survey conducted by the Seoul e-commerce center, 5 out of 10 consumers have experienced shopping through social media. The cost of traditional advertising media has been reduced and advertising spending on social media has risen by 74%, indicating that social media is becoming a more important marketing element. While the number of users of social media has increased and corporate marketing activities have increased accordingly, research has been conducted in various aspects of marketing such as user motivation for social media, satisfaction, and purchase intention. There was no subdivided study on the differences in the social media usage frequency of consumers in actual purchasing behavior. This study attempted to identify differences in consumer characteristics by cluster in the agrifood purchase situation by grouping them by type according to the frequency of use of social media for consumers who purchase agri-food online. Product involvement, product need, and online purchase channel Consumer characteristics such as demographic distribution, perceived risk, and eating and lifestyle in each cluster were checked for the three agrifood purchase situations including choice, and types for each cluster were presented. To this end, questionnaire data on the frequency of social media use and online agrifood purchase behavior were collected from 245 consumers, and the validity of the measurement variables was secured through factor analysis and reliability analysis. As a result of cluster analysis according to the frequency of social media use, it was divided into three clusters. The first cluster was a group that mainly used open social media, and the second cluster was a group that used both open and closed social media and online shopping malls; The third cluster was a group with low online media usage overall, and the characteristics of each cluster appeared. Through regression analysis, the effect on product involvement, product need, and purchase channel selection when purchasing agri-food online through each of the three clusters was confirmed through regression analysis. As a result of the regression analysis, the characteristic of cluster 1 in the situation of purchasing agri-food online is a male in his 30s living in a rural area who has no reluctance to purchase agri-food on social media or online shopping malls. The characteristics of cluster 2 are mainly consumers who are interested in purchasing health food, and the consumer characteristics are represented. In the case of cluster 3, when purchasing products online, they purchase after considering quality and price a lot, and the consumer characteristics are represented as people who are more confident in purchasing offline than online. Through this study, it is judged that by identifying the differences in consumer characteristics that appear in the agri-food purchase situation according to the frequency of social media use, it can be helpful in strategic judgments in marketing practice on social media customer targeting and customer segmentation.

Accessing movie contents has become easier and increased with the advent of smart TV, IPTV and web services that are able to be used to search and watch movies. In this situation, there are increasing search for preference movie contents of users. However, since the amount of provided movie contents is too large, the user needs more effort and time for searching the movie contents. Hence, there are a lot of researches for recommendations of personalized item through analysis and clustering of the user preferences and user profiles. In this study, we propose recommendation system which uses ontology based knowledge base. Our ontology can represent not only relations between metadata of movies but also relations between metadata and profile of user. The relation of each metadata can show similarity between movies. In order to build, the knowledge base our ontology model is considered two aspects which are the movie metadata model and the user model. On the part of build the movie metadata model based on ontology, we decide main metadata that are genre, actor/actress, keywords and synopsis. Those affect that users choose the interested movie. And there are demographic information of user and relation between user and movie metadata in user model. In our model, movie ontology model consists of seven concepts (Movie, Genre, Keywords, Synopsis Keywords, Character, and Person), eight attributes (title, rating, limit, description, character name, character description, person job, person name) and ten relations between concepts. For our knowledge base, we input individual data of 14,374 movies for each concept in contents ontology model. This movie metadata knowledge base is used to search the movie that is related to interesting metadata of user. And it can search the similar movie through relations between concepts. We also propose the architecture for movie recommendation. The proposed architecture consists of four components. The first component search candidate movies based the demographic information of the user. In this component, we decide the group of users according to demographic information to recommend the movie for each group and define the rule to decide the group of users. We generate the query that be used to search the candidate movie for recommendation in this component. The second component search candidate movies based user preference. When users choose the movie, users consider metadata such as genre, actor/actress, synopsis, keywords. Users input their preference and then in this component, system search the movie based on users preferences. The proposed system can search the similar movie through relation between concepts, unlike existing movie recommendation systems. Each metadata of recommended candidate movies have weight that will be used for deciding recommendation order. The third component the merges results of first component and second component. In this step, we calculate the weight of movies using the weight value of metadata for each movie. Then we sort movies order by the weight value. The fourth component analyzes result of third component, and then it decides level of the contribution of metadata. And we apply contribution weight to metadata. Finally, we use the result of this step as recommendation for users. We test the usability of the proposed scheme by using web application. We implement that web application for experimental process by using JSP, Java Script and prot$\acute{e}$g$\acute{e}$ API. In our experiment, we collect results of 20 men and woman, ranging in age from 20 to 29. And we use 7,418 movies with rating that is not fewer than 7.0. In order to experiment, we provide Top-5, Top-10 and Top-20 recommended movies to user, and then users choose interested movies. The result of experiment is that average number of to choose interested movie are 2.1 in Top-5, 3.35 in Top-10, 6.35 in Top-20. It is better than results that are yielded by for each metadata.

When Korean family planning services began as a part of the National Policy in 1962, the annual population growth was 3.0%. This growth rate has been decreased to 2.0% during last ten year period. And it seems imperative that all hospitals, as well as related organizations, should participate in family planning in order to contribute to achieving the National goal of 1.5% population growth by 1976, the end of the Third Five Year Economic Development Plan. Nurses should be considered the most important human resources in charge of the core of family planning services in any setting. For the family planning services in the general hospital setting, nurses as a core members contribute much as change agent, motivators, counsellors, educators etc. A nurse can work with patients and their relatives when she is equipped with relevant knowledge and skills. Fur the more family planning cannot be ignored even in hospital setting where more comprehensive nursing care is needed Thus, the general objective of this study is to provide baseline data for better programming of In-service education in family planning so that effective hospital family planning nursing services can be made a part of comprehensive nursing care contributing to the national population program and human welfare. In order to meet the general objective, this study has the following specific objectives : 1. To find out the general characteristics of the clinical nurses working in Y Hospital 2. To evaluate their attitudes and practices of family planning 3. To assess their knowledge, attitudes and practices of population and family planning as professional nurses. 4. To examine and compare data collecting methods for the planning of an In-service Educational Program 5. To explore the contents to be included in this In-service Education Program. The study population randomly selected one hundred nurses working in Y Hospital A cross-sectional survey with questionnaires developed for this study was chosen for the study method. To collect reliable data, the questionnaires were distributed to and answered by the study population in a controlled situation. X²test and t-test was employed in analyzing the data. The findings of this study are as follows: 1. Y Hospital nurses had a lower ideal number of children (X=2.02) and showed no strong preference for male children, and 74% of them expressed the desire to use permanent methods of birth control 2. of this thirty Y Hospital nurses who were married 66.7% stated they were already practicing contraceptive methods. Most of them preferred male methods of contraception. 3. According to objective evaluation about knowledge of various aspects of population and family planning, respondents from collegiate programs significantly knew better the subjects on the average than did respondents from diploma programs of nursing. 4. There was a marked difference in the results of self-evaluation and objective evaluation in their family planning knowledge. It was found that the self-evaluation family planning knowledge seemed to be unreliable. Accordingly, the objective test methods appeared to be more reliable in the evaluation of knowledge levels. 5. The subject areas needed to be included in In-service education for the Hospital family planning services in Y Hospital are 1) rhythm methods, 2) tubal-legation, 3) family planning effects of contraceptives, 4) population growth, 5) demographic traction, 6) population structure and 7) infant mortality facts. In addition, 1) various oral contraceptives, 2) basal temperature method, 3) laparoscopic female sterilization, 4) interfering factors of family planning, 5) anatomy and physiology of the female reproductive organs were additional areas to be taught to respondents from 3-year diploma schools of nursing.

The purpose of this article was to study how social workers' belief and behaviors with respect to ethical issues have changed during the past decade by comparing the results of studies carried out in 2001 and 2011, respectively. Focusing on dual relationship with clients, this article reviewed how social workers' belief and behaviors towards ethical issues have changed over the changing socio-demographic characteristics and varying properties of the organizations for which the workers provide services. To accomplish this purpose, we surveyed 356 social workers while the results of the survey was subjected to a comparative review with another research performed 10 years ago under a similar approach. Widely acknowledged during the survey was that the social workers appeared to have more rigid ethical standards compared to 10 years ago; however, they tended to be more permissive in certain issues such as bartering relationship and private relationship. In addition, according to the survey, belief and behaviors of social workers towards ethical issues varied depending upon their gender, education level, and the properties of the organization as seen in the survey in 2001 while the modalities have changed over the decade. Based on these results, it is suggested that the curriculum of social work ethics should be revised to reflect present field situation and inspire ethical sensitivity.

This study analyzed the necessity of detailed items of fundamentals of nursing education in college by soliciting answers from clinical nursing educators in hospitals and nursing professors. The questionnaire consisted of four parts. The first part included questions about the general demographic characteristics of respondents, the second part. questions about the general necessity of fundamentals of nursing, the third part, questions about the necessity of 26 items in fundamentals of nursing in knowledge education and about the necessity of 81 items in fundamentals of nursing in practice education, the fourth part solicited free description of ideas about the problems education in fundamentals of nursing in Korea. Thirty professors from universities, 30 professors from community. and 30 clinical nursing educators were randomly sampled and the questionnaires were sent by mail. Seventy people returned completed questionnaires. Ninety three percent evaluated fundamentals of nursing as necessary for nursing not only in knowledge education but also in practice education. They also generally agreed on what items are necessary for fundamentals of nursing. However. opinions about some items were split between nursing scholars and clinical nursing educators. Clinical educators wanted fundamentals of nursing to be more practical and to incorporate recent developments and changes in clinical settings. They described several problems in fundamentals of nursing. One was that some the content of fundamentals of nursing overlaps with other subjects, especially with adult nursing. Some respondents also thought that fundamentals of nursing included too many topics. These problems make it difficult for students, scholars, and nurses identify what fundamentals of nursing is. This causes an identity problem in fundamentals of nursing. Some disparity between clinical nursing and knowledge education in fundamentals of nursing was also reported. This was also related to problems lack of clinical experience in teachers of fundamentals of nursing. Some respondents suggested requiring clinical experience for professors or establishing a system of clinical professorship. Problems of teaching material were also pointed out. Fundamental nursing skills and knowledge in teaching materials are often old or not appropriate for the Korean nursing situation. The respondents urged the development of teaching materials appropriate for Korean nursing. In order to solve these problems, the authors suggest forming an ad hoc committee which can reformulate and standardize education in fundamentals of nursing in Korea.

This research examines the degree and the patterns of living arrangement transitions and analyzes the factors affecting transitions in living arrangement among elders in Korea. Data came from four-wave panel study of Hallym Aging Research Institute. The first wave was conducted in 2003, and each successive wave occurred exactly 2 years after. Respondents who were aged 60 and over, and had at least one living child were selected for this research. The baseline consisted of 1,907 respondents(2003), then became 985 for the fourth transition interval (2009). A total of 825 who participated both in 2003 and 2009 were used. Binomial logit regression analyses were used to analyze the effects of demographic characteristics, socioeconomic status, physical health, cognitive function, psychological well-being, and cultural attitudes toward elder care on transitions in living arrangements. Results show that 29.82% of the elders made transitions in living arrangements from 2003 to 2009, indicating remarkably unstable living situation over this time period. The ratio of living alone is increased from 17.6% to 19.6%, in contrast with decreased ratio of living with married children from 30.5% to 25.2%, and that of living with unmarried children from 19.9% to 13.7%. Factors affecting transitions in living arrangement were different according to types of living arrangement. Elders living with married children were more likely to be older, widowed and to have higher level of psychological well-being and more traditional attitude toward elder care. Elders living alone were more likely to be women, widowed, and to have more chronic diseases and lower level of psychological well-being.

Purpose - The TOEIC test has been leading the change in the quality and the globalization of companies for about last 30 years. The TOEIC test is taken by about two million people each year and is used as a criterion to select new employees in companies or government offices, for performance ratings, and for overseas posting selections. Universities also use TOEIC test in various ways. Since the TOEIC test is used for the selection of new students for admission, transferring extra credits, scholarships, graduation certification, and admission of international students studying abroad, many universities all over the country provide students with TOEIC study lectures through their own language institutes. Despite the fact, there has been no research on the service quality or even the current situation of these institutes. Thus, this study aims to evaluate the factors that impact TOEIC lecture service quality and analyzes the effect of the expectation related to the education service quality and the result of education on intentional behavior. Research design, data, methodology - Data was collected by administering a survey to current TOEIC students from different university language institutes. The survey questionnaire comprised of a five-point Likert scale. The demographic analysis was conducted using the frequency analysis method and the factor analysis was conducted to verify the validity of questionnaire over any variable. The reliability analysis was conducted to verify the reliability of the results. Besides, multiple regression analysis, regression analysis, and mediated effect verification were also conducted. For education service quality, four different independent variables such as reliability, response, conviction, and sympathy were considered using the SERVQUAL survey model. Based on the research models, the study hypotheses below were formulated in order to recognize an effect relationship between the variables. The four hypotheses are, "the hypothesis on education service quality and TOEIC study result expectation," "the hypothesis on education service quality and behavioral intention," "the hypothesis on study result expectation and behavioral intention," and "the hypothesis on study result expectation and mediated effect." Results - The results are as follows. First, the factors like response, conviction, and sympathy have a positive influence on TOEIC study result expectations. Second, the TOEIC study result expectation has a positive influence on the factors of behavioral intention such as re-sign up, positive word-of-mouth, "loyalty towards school." Third, it was verified that the mediated effect on behavioral intention was influenced by education service quality at university foreign language institute, while the study result expectation has only a partial mediated effect. Conclusions - The implications of this study are summarized as follows: First, it suggests a new research model for the effect of the expectation related to the education service quality and the result of education in the university language institutes on the behavioral intention. Second, it has established a relationship between the education service quality and study result expectation by verifying the mediated effect on them.
