  • The arc, generated by Tungsten Inert Gas(TIG) welding, is stable and provides excellent quality of the weld. Since automation is difficult, a lot of work is performed by hand. In addition, to obtain the uniform weld quality is difficult when using a base metal having a nonuniform welding line, or when welding inside a pipe. Generally, TIG welding power has the characteristic of constant-current. The welding voltage is changed in proportion to the arc length. Hence, the automatic voltage control equipment should be applied at the TIG welding system. The automatic voltage control equipment has been designed using LabVIEW software. It consists of a manufactured voltage divider circuit, and jig for moving the torch. The voltage measurements and driving of the motor were performed through the algorithm implementation in LabVIEW. Welding was conducted while increasing the arc length. In this process, it was confirmed that the automatic voltage control equipment kept the arc length constant.

  • It is becoming increasingly difficult for colleges to recruit new students to their full capacity. The increase of the withdrawal rate drives these colleges into crisis yet little has been done about it, because students with great possibility to withdraw enter colleges and old measures to stop them from dropping out hardly work. This study attempts to grope new measures to prevent dropout from college. To do this, I investigated withdrawal rate by college admission types and suggested measures to reduce withdrawal rate by incorporating the results of the investigation into admission procedures. I also compared the different types of admission in students satisfaction with college life and withdrawal rate, and suggested the measures to alleviated withdrawal rate. I expect the suggestions made in this study would be used effectively to reduce the withdrawal in colleges.

  • The purpose of this study is to investigate the priority order in the factors influencing college choice of students who are majoring in culinary art in Chungcheong-do. For the study, we set the decision-making factors of upper hierarchies and nineteen bottom hierarchies based on the literature review and employed the analytical hierarchical process(AHP). As a result, the first considering factor among 4 upper hierarchies for college choice was the educational environments of the department(0.378). The next came in the order named as follows: college and university grade(0.263), the educational environments of colleges or universities(0.244), recommendation(0.115). The first considering factor among the educational environments of the department was the aptitude for the major(0.323). The first considering factor in college and university grade was the entrance competitive rate(0.397). The first considering factors among the educational environments of the colleges or universities were scholarships and tuition fees(0.325). The first considering factor in recommendation was the recommendation of a high school teacher(0.295). This results of this study will contribute to the development of colleges and universities under the turbulent changes of educational environments.

  • The purpose of this study was to criticize (through available documents) the lecture in English at colleges. It is necessary that a study of English is emphasized in the era of internationalization. But, the indiscreet extension of lecture in English without consideration of the purpose, principle, and philosophy of college's education needs reflective thinking. This study criticized four dimensions, in other words the effectiveness of lecture in English, criteria of internationalization and college's competition of lecture in English, social inequality of lecture in English, and the harmfulness in the value of Korean language of lecture in English. First, most researches expressed the indiscreet extension of lecture in English was not effective in both students and professors. Second, many scholars and agencies on the internationalization and college's competition excluded the lecture in English as criteria. Third, the indiscreet extension of lecture in English had the possibility of social inequality. And fourth, the indiscreet extension of lecture in English had harmfulness in the value of Korean language and Korean's thought. College's education is an ivory tower in society. So, colleges should discard the thought that extension of lecture in English is the best way. Colleges should keep the purpose, principle, and philosophy of college's education.

  • This paper reveals the influence of urban and social contexts on the early building layout of Japan Women's College (JWC), one of the first women's colleges in Japan. According to the unpublished plans, the main building and other major structures, at the first stage, formed a three-sided quadrangle with site-wide organization, which was similar to contemporary National colleges. This impressive design, however, disappeared in the final plan. Although the school is the largest in student number and in campus ground size compared to other contemporary private colleges at its establishment, the subdivided land acquired in the private land market forced JWC to give up the organic composition of buildings. Under the framework of donation-based finance, it needed to start construction quickly for further support from the public, which prevented the school from acquiring enough time to adjust land ownership. These constitute the major differences with national schools. The founder's emphasis on the physical exercises, which reflected the public interest in physical strength of mothers in the time of wars, gave preference to securing sufficient open space over the order of buildings.

  • $M{\ddot{o}}nckeberg$ sclerosis is a disease of unknown etiology, characterized by dystrophic calcification within the arterial tunica media of the lower extremities leading to reduced arterial compliance. Medial calcinosis does not obstruct the lumina of the arteries, and therefore does not lead to symptoms or signs of limb or organ ischemia. $M{\ddot{o}}nckeberg$ sclerosis most commonly occurs in aged and diabetic individuals and in patients on dialysis. $M{\ddot{o}}nckeberg$ arteriosclerosis is frequently observed in the visceral arteries, and it can occur in the head and neck region as well. This report describes a remarkable case of $M{\ddot{o}}nckeberg$ arteriosclerosis in the head and neck region as detected on dental imaging studies. To the best of our knowledge, this is the first case that has been reported in which this condition presented in the facial vasculature. The aim of this report was to define the radiographic characteristics of $M{\ddot{o}}nckeberg$ arteriosclerosis in an effort to assist health care providers in diagnosing and managing this condition.

  • Graduates from engineering colleges are demanded to have been acquired some abilities and qualities during their undergraduate years through the standard of the so-called "programmed learning results and evaluation" This paper aims at analyzing the learning results evaluation tool for graduates from the architectural engineering department through the examples of the colleges with engineering accreditation in Korea, and suggesting a more appropriate programmed learning result evaluation tool. The basic theories on programmed learning results were studied, and then the previous study examples were researched. The study objects were limited to the fourteen colleges which offered the examples of the learning results evaluation tools of the colleges with engineering accreditation in Korea. Types and the present situation of those evaluation tools were analyzed. In addition, the proposals for the evaluation tool of programmed learning results and the performance standard were suggested for those with an engineering accreditation, based on the case study of the performance standards of each college with an engineering accreditation. The study results showed that much more national research needs to be conducted to clarify the standards of selecting an evaluation tool and a performance standard appropriate for the level of each college so that it can make a proper proposal.

  • We investigate the type of self-selection arising in college transfer in Korea, and then estimate the returns to additional college education gained through transfers from junior colleges to four-year colleges or universities. In this paper, we show that academic transfer is consistent with a positive selection hypothesis, in a sense that students with characteristics correlated positively to productivity are more likely to transfer to four-year colleges from junior colleges. These empirical results also meet an underlying dispersion condition. In addition, we find that the transferred would make a statistically significant return to additional college education.

  • With the aim of examining the effects of implementing international financial reporting standards (IFRS) on teaching accounting and auditing at universities and colleges in Vietnam, a case study was conducted at 30 universities, colleges, and 208 lecturers in Vietnam. Next, the study employed the structural model analysis method by PLS_SEM software to process and analyze the collected data. The research results show that: (1) There are eight factors that affect how IFRS is applied to teaching, including the training program, (ii) teaching staff, (iii) IFRS application regulations, (iv) related party requirements, (v) faculty/school administrators, (vi) teaching aids, (vii) IFRS teaching methods, and (iii) students; (2) there are three factors that affect the quality of teaching staff, including applying IFRS to teaching at the university and colleges, (ii) Regulations on the application of IFRS, (iii) Requirements from related parties. At the same time, the study also shows that, regarding the indirect relationships, applying IFRS to teaching does not play an intermediary role in these relationships. However, at the 10% significance level, it was found that there is an indirect relationship between regulations on the application of IFRS by the Ministry of Finance and the quality of teaching staff through the variable applying IFRS to teaching.

  • The purpose of this study is to propose a strategy model for engineering education for citizen through the connection between colleges of science and engineering and science museums as a way to achieve citizen science. For this model, the role of universities was redefined as social contributions through engineering education from the perspective of knowledge triangle and university entrepreneurship. In addition, the science museum was re-examined as an engineering education platform and selected as an institution that supports the contribution of colleges to society. For practical model development, the connection types of these two institutions were analyzed as case studies and interview to collect opinions from experts in the science museum. In this process, convergence education content development, reinforcement of college-science museum linkage, infrastructure construction, development of college resource utilization plans, and maintenance and expansion of educational programs diversification were derived as components for model development. Based on this, engineering education model for citizen was presented that matches educational programs according to the type of participation of colleges including key factors and considerations.
