In this paper, we examined informatics textbooks for middle school students in accordance with 2009 revised curriculum through conducting both content analysis and surveys. The content analysis was analyzed the composition and contents of textbooks. Survey questionnaires were based on the authorization criteria and selection standards of informatics textbooks. The content analysis demonstrated that there were discrepancies among textbooks in areas such as the total number of pages, related material, the number of core concepts introduced in each chapter, and the application of software. The survey results showed that two sections - 'Expression and Modification' and 'Text' exhibited the most positive results, and the 'Creativity' section the least. Using the findings above, we present alternative ways to improve qualities of these textbooks.

A new mesh reconstruction scheme for approximating a surface from a set of unorganized 3D points is proposed. The proposed method, called a shrink-wrapped boundary face (SWBF) algorithm, produces the final surface by iteratively shrinking the initial mesh generated from the definition of the boundary faces. SWBF surmounts the genus-0 spherical topology restriction of previous shrink-wrapping-based mesh generation techniques and can be applied to any type of surface topology. Furthermore, SWBF is significantly faster than a related algorithm of Jeong and others, as SWBF requires only a local nearest-point-search in the shrinking process. Our experiments show that SWBF is very robust and efficient for surface reconstruction from an unorganized point cloud.

As society gradually enters a virtual, non-face-to-face society, the use of online content is increasing as well. In particular, as smartphones are thoroughly established in our daily life, the platforms of webtoons, mobile broadcasting, and education are shifting from personal computers to smartphones. Recently, the development of the Over-The-Top media service (OTT service) enabled streaming services of various media contents through the internet and activation of IPTV. Therefore, the rapid increase of popularity of short-form content is a natural phenomenon with smartphone platforms with fast, improvised, and endless communication. Lately, TikTok became the favored platform with prosumers, defined as people who are both producers and consumers. In this study, I studied the experiential response of YouTube and TikTok users as representative examples of a short-form content platform developed after the 2000s, the flourishing years of digital content with a length of 30 seconds.

This case study explored the potential for implementing content-based English as a Foreign Language (EFL) instruction in a Korean middle school facilitated by computer-mediated communication (CMC). The instructor scaffolded the student participant's language learning online, helping her to produce English output on her own. While experimental social studies lessons on the topic of stereotyping were taught, data were collected on the student's online exchanges with her counterpart in Iran about their respective cultures. Findings show that the student from Korea was able to better understand her own culture as a result of the online experience. This interaction and the in-class lessons have demonstrated that content-based EFL instruction is a viable alternative to the school's existing curriculum.

The objective of this study was to develop evaluation criteria for forest education using the Context, Input, Process, and Product (CIPP) model. To this end, we designed a survey based on expert advice and content analysis of previous studies on the CIPP model and forest education. The survey was conducted on 393 forest education specialists, and Cronbach's α coefficient was set as 0.6 or higher to verify reliability and validity, and to determine reliability by factor. Eventually, 52 out of 57 evaluation items were extracted, and the evaluation indexes were selected through factor analysis as follows: four evaluation indexes for the context dimension, namely "Clarity of goal setting," "Developing conditions for education," "Meeting of requirements," and "Institutional drive"; three evaluation indexes for the input dimension, namely "Acquisition of education infrastructure," "Establishment of operational support," and "Adequacy of assigned manpower"; four evaluation indexes for the process dimension, which were "Adequacy of budget allocation," "Expertise of forest education instructors," "Diversity of programs," and "Public-private academic partnership"; and five evaluation indexes for the product dimension, namely "Effectiveness of perception change," "Influence over the society," "Continuity of improvement in evaluation," "Continuity of education," and "Verification of the effects of education."

Strengthening of software education is a big trend worldwide recently. Based on this trend, the Ministry of Education issued a domestic content to enhance software education in September 2014. In this regard, the most important problems are the number of available teachers who can adequately teach computational thinking in the pursuit of new software education and the teaching competencies of teachers in charge of software education. These problems are the same issues emerged in the United Kingdom where computer science education became mandatory for all primary and secondary students from September 2014. This study examines how the United Kingdom and the United States have solved these problems and discusses the realistic solutions for our country.

In order to adapt to the rapidly changing medical environment, it is important to advance not only the basic medical education in medical schools but also that of residents. The quality of the training environment and educational goals for residency must also be improved for specialists. Although each institute including internal medicine, general surgery, family medicine, etc., strives to standardize, sets educational goals, and develops content to train capable specialists, the education programs focus on special techniques and competency of medical care for patients. The training environment of each residency program is different in each trainee hospital, and hospitals are making an effort to set education goals for the residents and improve their education programs. In Korea, there is no common core education program for residents, while in the United States, the Accreditation Council for Graduate Medical Education is responsible for the development and evaluation of a standardized curriculum for residents, and in Canada, CanMEDs presents a basic curriculum to help residents develop competency. Fully capable specialists have more than just clinical competency; they also need a wide range of abilities including professionalism, leadership, communication, cooperation, in addition to taking part in continuous professional development/continuing medical education activities. We need to provide a core curriculum for residency to demonstrate attention to and knowledge about health problems of the community.

This study was done to examine knowledge about, and need for sex education among university students in Korea. This study design was descriptive survey design. The data were collected from 540 university students from June 10 to June 30, 1996, using questionnaires developed by the authors. The results are as follows : Those who had sex education had higher scores in sex knowledge than those had not had sex education. The average score for sex knowledge was 71.9 of a maximum score of 100. Knowledge of sexually transmitted disease was scored highest of 79.8, and knowledge of the anatomy and physiology of the reproductive system was scored lowest at 60.9. The subjects who answered 'yes' about the necessity of sex education numbered 529(98%) and the most important reason given for needing sex education was to cope well with physical and psychological developments. Regarding the content of sex education, a choice of relevant contraceptive methods was given the highest rating. Anatomy and physiology of reproductive system was the least choser subject as the first priority among five topics. Yet, sex education for university students should include anatomy and physiology of the reproductive system, considering the low level of knowledge on this topic in the subjects of this study and its importance as a part of sex education.
