Due to the growth of digital media technology, there is increasing demand of personalized education based on context data of learners throughout overall education area. For music education, several studies have been conducted for providing appropriate educational contents to learners by considering some factors such as the proficiency, the amount of practice, and their capability. In this paper, a technique has been defined to recommend the appropriate music scores to learners by extracting and analyzing the practice data and chord data. Concretely, several meaningful relationships among chords patterns and learners were analyzed and visualized by constructing the learners' profiles of proficiency, extracting the chord sequences from music scores. In addition, we showed the potential for use in personalized education by analyzing music similarity, learner's proficiency similarity, learner's proficiency of music and chord, mastered chords and chords sequence patterns. After that, the chord practice programs can be effectively generated considering various music scores using the synthetically summarized chord sequence graphs for the music scores that the learners selected.

After the work-study combination PBL method was first introduced into the P-Tech type in 2018, it was introduced into the degree-linked high-skilled professional course in operation as a pilot project in 2020, and ever since each department has reorganized the standard completion system to meet the PBL operation regulations and developed and operated PBL-based learning and training courses accordingly. With the expansion of the work-study combination PBL in 2021, the operating regulations were revised more elaborately. This paper examined the characteristics of the work-study combination PBL, the PBL operation regulations for each degree-linked high-skilled professional course, and the most recently implemented PBL operation regulations in detail through literature research. Based on this research, it introduced the development process and the result of the PBL-based standard completion system by the IT Convergence SW Engineering Department of KOREATECH and the result of the survey conducted to verify the suitability of the standard completion system after an operation and presented the challenges and improvements required for the degree-linked high-skilled professional course in relation to the changing operation regulations for the work-study combination PBL. This study is expected to provide universities with a reference to the development of training courses to smoothly apply the work-study combination PBL. It is also expected to contribute to the establishment and steady expansion of a unique PBL system that reflects the characteristics of work-study combination by presenting discourses on how the work-study combination PBL should develop, including high-skilled professional courses.

This article is concerned with exploring labour market transformation in newspaper industry and thereby looking into skill formation and professionalization of journalists. In Korea, according to previous research, newspaper journalist labour market had been characterized by a low inter-firm mobility of workers and patterns of long-term employment and firm-based skill training. However, over the past few years, as new product strategies of newspaper firms has changed due to management crisis employers pull back from the responsibilities of investment on skill training and securing job stability for journalists. However, in spite of overall weakened firm-based skill formation systems within the market, there still seems to be long way to build alternative systems of skill developments for them. As a result, it will be argued that, in the absence of manifest labor market institutions such as apprenticeships or skill certification system, which are assumed to traditionally certify workers' professionalization, occupational identity and professionality of newspaper journalist labour market will be weakened. Labor market data from interviews with journalists in the newspaper industry are used in order to test this hypothesis.

This study presents the new method which can transfer the expert's skill to deburring robot through neural network. The expert's skill is expressed as association mapping between the characteristics of the burr and human expert's action. Under the fundamental idea that the state of the deburring process can be extracted via the visual sense of the human, we employ vision system for the perception and identification of the changing burr. From the demonstration of human experts, force data are measured. Finally the characteristics of the burr and corresponding force are associated by the neural network which is trained through many demonstrations. The proposed method is verified in the deburring process of welding burr.

컬러매지니먼트는 예전에는 작업자의 예리한 시각과 일관성을 유지할 수 있는 숙련된 경험에 의지했다. 그러나 오늘날에 이르러 디지털 기술의 발전에 따라 대량 부수의 인쇄, 재판 인쇄가 이뤄지는 물량에 대한 컬러매니지먼트는 개인의 능력보다 예술적인 수준의 높은 단계까지 올려 놓은 하이테크 작업에 의존하는 방식으로 진화했다.

젖소로부터 우유를 생산하기 위해서는 매일 2~3회의 착유가 이루어야 한다. 그러나 국내 낙농가는 고령화되고 노동력이 부족해 하루 2회 이상 착유가 이루어지지 않는다. 또한 착유 시 중요한 작업인 유두를 세척하는 작업의 경우 세척자의 숙련도에 따라 차이가 크고 손에 의한 유방염 원인균의 전파 가능성이 높은 상황이다. 이에 농촌진흥청에서는 젖소 유두 세척 장치를 개발했다.

The purpose of this study was to examine the putter head movement during the putting strokes. Highly skilled 5 golfers(less than 3 handicaps) and 5 novice golfers(having no golf experience) participated in this study. A target distance was 3 m. Movements of the putter head were recorded at 60 Hz with two video cameras(1/500 shutter speed). The results showed that the angle of the clubface of expert golfers was almost 1 degree, but the novice golfers were more than 6 degrees. Expert golfers moved their hands faster than the head movement, therefore the clubface was not opened during impact. However, the novice golfers moved their hands slower than the head movement, therefore the clubface was opened during impact. The ratio of input and output angles of total movement was 1:3-4, however, the ratio of input and output angles of impact zone was 1:2. The angle of normal vector of expert golfers was less than the angle of normal vector of novice golfers.
