This research analyzed the contents of the high school home economics textbooks within the 7th Curriculum from three theoretical viewpoints: structure functionalism family development and healthy family. A quantitative and in-depth content analysis were carried out with the six elements of family structure, family role, family relation, family life cycle, adjustment to the aged, marriage and childbirth. From the in-depth analysis, a healthy family viewpoint was reflected in the family structure, family role, adjustment to the aged, marriage and childbirth elements and a structure functionalist viewpoint was found in the family relation element. The family life cycle elements reflected a strong tendency of family development theory. The quantitative content analysis consisting of pictures, illustrations, examples indicated that a structure functional viewpoint was prevalent in both the family structure and family role elements. Overall, structure functionalism and healthy family viewpoint were reflected at similar level in the textbook. Implications for curriculum development, teaching methods and future study were suggested.

This study delineates how recipients access, understand, and make use of social welfare information in their life-worlds. Through this vivid illustration about recipients' information behaviors, this research aims to suggest that government-centred welfare informatization policy should be readjusted. South Korean government has made enormous efforts to deliver and share social welfare information and knowledge with recipients, by organizing IT eduction programmes, offering free computers, and opening welfare portals. However, despite of such endeavors, not a few recipients find difficulty in gaining, grasping, and using welfare information. In fact, welfare informatization programmes have so far been initiated by the governmental bureaucratic system, and the voice of recipients have hardly been reflected on the informatization policy. Starting from this problem, this study examines how low-income recipients perceive and accept social welfare information in their daily lives and reflects on social welfare information at their point. For this purpose, this research conducted in-depth interviews with 14 recipients and analyzed the data using a framework analysis method. Based on the results, it raises the need for the remodelling of current welfare informatization measures from the perspective of recipients rather than following the custom of the bureaucratic system.

This research investigates the causes of infringements related to authors' moral rights which has most conflict among moral rights of authorship, through analysis of judicial precedents and compare whether there subsists any differences in viewpoints between judicial precedent trend and those on behind the scene of broadcast production. Copyright is divided into intellectual property and moral rights of authorship. Right to the integrity of the work is part of moral rights of authorship and produce one content and used in various media. When the edit is needed to fit the organization and advertisement time, advanced consultation from the rightful owner or written consent is needed. However, under the time pressure or ignorance of copyright, the arbitrary edits are made and content is used. This infringes the right of the integrity of the work. When we produce and use cinematographic works and other audiovisual works, there are considerable variablilies stemming from authorship, production cost and program staff. Therefore, prior conscent is needed to acquire and use the copyright in a proper manner. However, due to production-oriented environment and low understanding of the copyright protection, we usually depend on the users' work practices rhather than insufficiency of copyright laws in dealing with the infringement of right to the industry. In conclusion, we need to provide meticulous work manual and to focus on systematic eduction of professional copyright manpower.

Coinciding with the advent of COVID-19, online education is on the rise both domestically and globally, and has become an absolutely necessary and irreplaceable form of education. It is a very curious question what the perception of people about the suddenly growing form of education is, and how it has changed. This study investigated changes in consumers' perception of online education using big data. To this end, we divided the time into four stages: before COVID-19 (November to December 2019), after the triggering of COVID-19 (January to February 2020), right after the online classes started (March to April 2020), after experiencing some online education (May to June 2020). Then we conducted text mining, namely, keyword frequency analysis, network analysis, word cloud analysis, and sentiment analysis were performed. The implications derived as a result of the analysis can help education policy makers and educators working in the field to improve online education quality and establish its future directions.

This study was attempted to derive strategic implications for activating professional sports by conducting in-depth interviews with professional sports officials such as players, teams, federations, agencies, etc., by searching for factors that cause match fixing and deriving preventive strategies based on them. Eight people with more than 3 years of experience working in professional sports were selected using the snowball sampling technique. Data were collected and analyzed by applying a semi-structured in-depth interview method for them. As a result of the analysis, five core categories (the learning effect from the cartel for entering university, the culture learned in a camp training, the manifestation of the latent learning effect, the negative effect of the human network, the personal disposition) were derived as factors causing match-fixing. As for the strategy to prevent match fixing, first, improving the college entrance examination system oriented on individual capability, second, improving the education system for student athlete, third, establishing a prevention system, fourth, continuing education, fifth, and activating the agent system as the core categories. Implications for the derived research results and future research directions were discussed.

In this study, a plastic bottle recycling bin system that utilizes an infrared sensor was implemented. The proposed system consists of a recognition unit, a control unit, an alarm unit, and a driving unit. The recognition unit detects the plastic bottle, measures the distance between the plastic bottle and the infrared sensor, extracts the value of the bottle, compares the extracted value with a standard range, and then transmits the control value to the control unit if the extracted value of the bottle is outside the standard range. In this case, the result of the presence or absence of a brand label or bottle cap is transmitted to the controller. The control unit opens the entrance of the recycling bin or alerts the alarm unit according to the result value transmitted from the sensor unit. In order to implement the proposed system, the recognition unit was implemented with an infrared sensor, and the control unit was made with an Arduino IDE controller, based on the C programming language. Additionally, the recognition unit and the control unit are able to communicate using analog signals. The proposed system accurately judges the presence or absence of a brand label and bottle cap of plastic bottles according to a predetermined algorithm. It then blocks the entrance of the recycling bin when a brand label or bottle cap is still attached. As the amount of waste discharged per person is relatively high and the majority of such waste is incinerated rather than recycled, the system proposed in this study is expected to increase the recycling rate of plastic bottles.

Radiofrequency ablation (RFA) is a minimally invasive treatment modality used as an alternative to surgery in patients with benign thyroid nodules and recurrent thyroid cancers. In Korea, RFA for thyroid nodules was first performed in 2002, and a large population study was published in 2008. The Task Force Committee of the Korean Society of Thyroid Radiology (KSThR) developed its first recommendations for RFA in 2009, which were revised in 2012 and 2018. The KSThR guideline was the first guideline for RFA of thyroid nodules worldwide and has become a guideline for physicians to perform thyroid RFA in Korea and other countries around the world. These guidelines have contributed significantly to the establishment and widespread use of RFA worldwide. In addition, since 2015, the KSThR has conducted intensive hands-on courses depending on the level of the participants. In this article, the authors introduce the history of eduction for RFA conducted by the KSThR and describe the learning curve of RFA and current training programs in Korea, along with future directions for training programs.

This research looks at the effects of portfolio-based lessons to help female middle school students understand and develop their self identity, and to examine the influence of various factors within the school and home environment. The participants were 256 female middle school students in Gangneung-si, Gangwon-do and the analysis was done using the SPSS/WIN 12.0 program. The 6 portfolio-based teaching lessons were made with the aim of developing each subordinate scope in every module for development of self-receptiveness, uniqueness, closeness, tendency of planning the future, and independence. Results of the pre and post-test revealed that scores of self-receptiveness and uniqueness increased. Content analysis revealed that the students pursued their talents and interests through the portfolio activities, and made specific plans for their future careers. In sum, the results demonstrate that the students became specifically and systematically concerned about their future career. The results of hierarchical regression showed that self-receptiveness developed when their parents' attitudes were not rejecting and their peer relationships were positive. Uniqueness was shown to develop as the fostering attitudes of parents were receptive. Closeness developed as fostering attitudes of parents were receptive and as their relationships with peers were positive. The students' tendency to plan the future developed as fostering attitudes of parents were receptive and as their relationships with teachers were good, and independence was shown to develop as the fostering attitudes of parents were not rejecting. Results of a two-year follow-up study appeared that self-receptiveness scores decreased as time passed, so students had highest scores in their first year and lowest scores in their third year. Scores of uniqueness, tendency of planning the future, and identity increased in the students' second year and then remained steadily afterward.

The objective of this study was to investigative the effects of amino acids supplementation on maturation, fertilization and embryo development of pig oocytes. Essential amino acids (EA), non-essential amino acids (NA) or both amino acids (EA + NA) were supple-mented to North Carolina State University (NCSU) 23 medium containing porcine follicular fluid (pFF). When the amino acids were supplemented to the maturation medium, the maturation rates were higher (p<0.05) in the NA group than control ($83.3{\pm}0.04\%\;versus\;70.0{\pm}0.05\%$, but the subsequent cleavage rates and development to morula and blstocyst stage between aminoacid supplement groups and control were not different. The developmental rates to morula and blastocysts stage were not significantly different regardless of amino acid supplementation to culture medium. In addition, supplementation of amino acids did not significantly affect the rate of fertilization and polyspermy. When the amino acids were supplement to culture medium, the number of trophectodermal (TE) cells was significantly (p<0.05) higher in amino acid supplement group than that of control ($18.6{\pm}0.5\;versus\;16.1{\pm}0.6$), whereas the numbers of inner cell mass (ICM) cells were not different among the treaonent groups and control ($29.0{\pm}0.9\~31.5{\pm}1.2$). Total cell number was also significantly (p<0.05) higher in EANA group ($50.0{\pm}1.0$) than that of control group ($44.2{\pm}1.1$). These results indicate that the amino acid supplementation to maturation and culture medium may not significantly stimulate early embryo development, but may improve the TE cell number of blastocyst stage in the pig.
