We collected survey data from those who have Vocational Training Teachers' Qualification to investigate the workplace characteristics and job satisfaction of the qualified people. Also, this study analyzed the determinants of the Vocational Training Teachers' monthly wages. Statistically Significant variables were male, age, graduated from graduate school, work duration, total work hours, regular workers, and levels of the certification. Since previous studies argued that the levels of the certification did not have effect on the wage, result of this study suggested that the further study and discussions on the effect of the levels of the certification was needed.

This study was conducted to compare the learning styles and self-leadership between engineering college students with high and low team performance records. About 70% of students in high team performance group showed learning styles of converger and accommodator, whereas about 67% of students in low team performance group showed learning styles of accommodator and diverger. In regard to self-leadership, high team performance group showed higher level of self-leadership, especially self-observation, self-punishment, natural reward strategies, visualizing successful performance, self-talk, and evaluating beliefs and assumptions. It is recommended to provide the engineering students with the specialized training program to complement their learning styles and self-leadership strategies.

본 논문에서는 한국어 의학 논문의 요약문으로부터 자동 영문 MeSH 키워드 제안 시스템을 소개하고, 띄어쓰기 변이(spacing variant) 문제를 해결할 수 있는 방법을 제안한다. 띄어쓰기 변이란 표준 한글 맞춤법에 비해 다르게 띄어쓰기된 것을 말한다. 이를 위해 시소러스에는 생성 가능한 모든 띄어쓰기 변이 대신에 최대 띄어쓰기 어구만을 저장하고, 문서에서 K-MeSH 용어를 찾기 위해 음절단위 부분문자열 검색을 사용한다. 이 방법으로 한국어 의학 논문의 요약문에서 K-MeSH 용어를 추출한 후, TF-IDF 순위 함수를 이용하여 상위 10위내의 키워드를 저자가 선정한 영문 키워드와 비교한 결과 58%가 일치하였다. 이는 기존 방법에 비해 42%정도의 시소러스 크기가 축소되었고, 상위 10위내에서 영문 MeSH 키워드 추천 재현률이 약 7.8% 증가한 것으로 효과적인 방법임을 보여주었다.

This study is about the effectiveness of Jahwal consulting. We analyzed 275 self-supporting participants of 58 self-supporting companies in eight wide-area self-supporting centers nationwide. After consulting by conducting a questionnaire before consulting, we conducted a questionnaire to analyze the differences. The measurement variables consisted of 3 variables and 6 subparameters. The top variables are interpersonal relationships, organizational systems, and self-help business will. The sub-elements are interaction, communication between members, horizontal leadership, organizational stability, personal suitability and developability. The questionnaire was analyzed using SPSS 21.0, frequency analysis, and t-test. The purpose of this study is to verify the effectiveness of consulting conducted by Jahwal institutions. For this reason, we developed a measurement scale, and analyzed changes before and after consulting using that scale. As a result of the analysis, it was found that self-help consulting is effective. It was also analyzed that there was mode significance in the analysis by gender, age, region and educational background.

To improve the resolution of complex flow field features, grid adaptation scheme of Anderson has been revised, which was based on the Poisson grid generator of Thompson. Anderson's original scheme adapts the grid to solution automatically, but if flow field is more or less complex, then the adaptivity is weak. So the technique of using threshold which is used in unstructured grid system is adopted. The regions of large variation in the solution are marked by marking function which has the property of total variation of the solution, and these regions have same values of weight but other regions are neglected. This updated method captures shocks clearly and sharpy. Four examples are demonstrated, (1) Hypersonic flow past a blunt body, (2) High speed inlet analysis, (3) Supersonic flow of M=1.4 over a 4% biconvex airfoil in a channel, (4) Hypersonic shock-on-shock interaction at M=8.03.

우리나라의 자영업자 비율은 G7보다 높은 수치로서 OECD회원국들 중 상위에 속하며, 그 중에서도 소상공인은 전체 사업자 수의 93.3%에 달한다. 하지만 2020년 3/4분기 기준 서울시의 소상공인 5년 생존율은 38.4%에 불과하며, 대표적인 폐업/업종전환 고려 이유는 수익성 악화, 판매부진, 경기불황이다. 이처럼 폐업한 소상공인들은 취업을 하거나 기존 업종으로 다시 창업을 하는 경우도 있으나, 새로운 업종에 도전하기도 한다. 그러나 재창업의지에 대한 선행연구는 많은 반면, 업종전환 및 업종전환 의지는 아직 심도있게 연구된 바 없다. 본 연구의 목적은 사업에 실패한 뒤 재창업을 하였거나, 사업에 실패한 뒤 재창업을 목표하는 소상공인을 대상으로 창업 실패 경험이 업종전환 의지에 미치는 영향 관계를 검증하는 것이다. 따라서, 본 연구에서는 소상공인의 사업 실패 경험이 업종전환 의지에 미치는 영향의 탐색적 연구를 사회적지지 조절효과를 중심으로 진행하였으며, 소상공인의 사업 실패 경험이 업종전환 의지를 높인다는 인과관계를 검증하고자 한다.

This paper discusses life expectancy differentials of beneficiaries of national pension old-age benefit and benefit-cost analysis in Korea. These results are useful indicators for the assessment of retirement income security of beneficiaries and old-age benefits. This paper analyzes benefit-cost ratio, internal rate of return and generation transfer amount, using life tables by lifetime incomes. The result of the actuarial analysis for male life expectancy is approximately 21.69 to 24.63 years. The result of the actuarial analysis for female life expectancy is approximately 27.63 to 29.81 years. The result of the actuarial analysis of low income level is that the benefit-cost ratio is lower approximately 2.68 to 4.83%, the internal rate of return lower approximately 0.00 to 0.74%, the generation transfer amount lower approximately 3.00 to 5.74%, than total income level. The result of the actuarial analysis of high income level is that the benefit-cost ratio is higher approximately 2.07 to 4.98%, the internal rate of return higher approximately 0.03 to 1.73%, the generation transfer amount higher approximately 2.53 to 9.68%, than the total income level. The results by income varies due to the effect of income redistribution and life expectancy on the national pension.

This paper deals with the passenger transfer trips counted from smart bus-card data from Seoul transit network to understand the current operational condition of the system. Objective of this study is to relocate the location of the transit transfer centers. It delivers a bi-level programing model. The upper model is a linear 0-1 binary integer program having the objective of total travel cost minimization constrained by the number of transfer centers and the total construction budget. The lower model is an user equilibrium assignment model determining the passengers' route choice according to the transfer center locations. The proposed bi-level programming model was tested in an example network. The result showed that the proposed was able to find the optimal solution.

The fracture processes under dynamic loading in tension were simulated using a proposed numerical approach and analyzed to determine dynamic tensile strength. The dynamic tensile strength and the scatter of the strength data decreased with increasing uniformity coefficients. The differences of static and dynamic tensile strength were due to the stress concentrations and redistribution mechanisms in the rock specimen. Although there were different mechanisms for the static and dynamic fracture processes, the static and dynamic tensile strengths were close to the mean microscopic tensile strength at high values of the uniformity coefficient. This paper shows that the rock inhomogeneity has an effect on dynamic tensile strength and is a factor that contributes to the different specimen strengths under dynamic and static loading conditions.

The growth of blogs has two aspect of providing various information and marketing. This study collected the rankings of blog posts of large portal using OpenAPI and investigated the features of blogs ranked through the exploratory data analysis technique. As a result of the analysis, it was found that the influence of the blogger and the recent creation date of the post were highly influential factors in the top rank. Due to the weakness of these evaluation algorithms, there was a problem of showing the search results which is concentrated to the power blogger's post. In this study, we propose an algorithm that improves the reliability of content by adding the reliability DB information which is verified by the experts and reflects the fairness of the application of the ranking score through the trend index indicating various public interests. Improved algorithms have made it possible to provide more reliable information in the search results of the relevant field and have an effect of making it difficult to manipulate ranking by illegal applications that increase the number of visitors.
