This study was conducted to investigate and reveal secondary vocational education institutions' perception changes and suggest the need for supporting the improvement of their perception by analyzing middle school principals' perception changes of the past, the present, and the future about them. For this, middle school principals' perception of the past, the present, and the future about secondary vocational education institutions was investigated and analyzed targeting 214 persons. The results of the study are as follow: First, middle school principals' perception of secondary vocational education institutions has found to make more positive changes in the present than the past and be going to make more positive changes in the future than the present. This can be interpreted that various policies of secondary vocational education institutions have a positive effect on the improvement of their perception since 2005. Second, in the result that analyzed changes in the ranks about middle school principals' perception of the past, the present, and the future about secondary vocational education institutions, the fields of "nurturing students' aptitude and talent early" and "their fast financial independence after graduation" were recognized as positive in the past, the present, and future. As the field of "entering universities in the same field easily" was recognized ranking high in the past and the present, but doing low in the future, it has found that the perception of secondary vocational education institutions is changing according to governmental policies' directions.

The mathematical ability is an essential element for achieving professional competencies and for enhancing application ability in a vocational world and exploring its experiences. In this aspect, for vocational high school students, it is an important and urgent issue to develop remedial learning programs for developing mathematical basic and application ability. In particular, the program is developed based on the individual achievement level, focused on a mathematical basic ability to be applied efficiently in a vocational world. Because of this reason, in this study, the program is comprised of two phases; one is diagnosis test and the other is remedial teaching and learning materials. Then, diagnosis test includes three test; I) level testing evaluation for selecting the subject of remedial learning, ii) pre-test for deciding on which area and level of the materials when students begin to study, and iii) post-test for confirming the learning status is satisfied and the possibility of next step(level) or the other area of the materials. To accomplish this, this study tried to devise an efficient remedial learning system. Based on the system, this study developed remedial learning programs on the four areas of number and quantity, change and relation, uncertain thing, and figure and shape in the middle school level. In particular, this program is comprised of two types of knowledge. One is K-knowledge which is an essential knowledge to achieve a basic mathematical ability. The other is C-knowledge which is the advanced knowledge required to apply efficiently in a vocational world. This paper deals with the content mentioned above, but examples of the materials is shown focused on the area of change and relation.

In this paper, we analyzed wage determinants of the vocational high school graduates utilizing both individual-level and work region-level variables. We formulate the models in the way wage determination has multi-level structure in the sense that individual wage is influenced by individual-level variables (level-1) and work region-level (level-2) variables. To incorporate dependency between individual wages into the model, we utilize hierarchical linear model (HLM). The major results are as follows. First, it is shown that the HLM model is better than the OLS regression models which do not take level-1 and level-2 variables simultaneously into account. Second, random effects on sex, maester dummy and engineering dummy variables are statistically significant. Third, the fixed effects on business hours and mean wage of regular job for level-2 variables are statistically significant effect individual-level wages. Finally, parental education level, parental income, number of licenses and high school grade are statistically significant for higher individual-level wages.

The purpose of this research is to identify how industrial highschool try to organize and apply NCS based curriculuma, to find out problems, and to suggest what the task for the sustained development and growth under the NCS based industrial highschool curriculum In order to identify actual situation and problems, when a industrial highschool organize and apply NCS based curriculum, we suveyed NCS based curriculum that 583 specialized, Meister highschools organize. The problems to identify through analysis about NCS based curriculum that schools organize are the followings First, schools' NCS based curriculum is set up too much comprehensive type for training human resources. Second, carreer path of students is not considered by schools' NCS based curriculum. Third, yearly plan for schools' NCS based curriculum is not balanced to raise working experience skill among each grades. Forth, schools are not ready to use NCS learning module. Task to solve these problems are the following. First, schools' curriculum have to be organized on the basis of NCS's purpose. Second, teachers have to restructure the NCS learning module in order to go up availability of NCS learning module. Third, industrial highschools have to make efforts to raise students' working experience skill. Finally, industrial highschools have to make efforts to raise teachers' competency to need that they teach and train their students' working experience skill.

The study tried to investigate the school curriculum organization and teacher's perceptions about test subjects in vocational education division of the college scholastic ability test based in the 2015 revised national curriculum. This study asked vocational teachers to fill in basic questionnaire that consists of 9 relevant and subjective items for the school curriculum organization and test subjects in vocational education division of the college scholastic ability test based in the 2015 revised national curriculum. For this, the survey was conducted 58 schools of 92 schools in technical specialized high schools, meister high schools and vocational high schools about test subjects of 2015 revised national curriculum. As a result, the 'Successful career life' subject was 53.5%, the most organized in the first grade. 'test course 1' was 55.2% and 'test course 2' was 72.4% the most organized in the first grade. The Opinions on the test courses were the highest in the two subjects in the same series as the present. The teacher's perceptions showed that the current test subjects in vocational education division of the college scholastic ability test are valid. The most important factor affecting difficulty was 'The Ministry Education's policy' in vocational education division of the college scholastic ability test.
