This study analyzes the perceptions of college students majoring in aviation services according to the field learning program conducted during their major studies in order to reflect the educational value and academic awareness of the experience of the experiential field learning program. A survey is conducted targeting college students who experience a field learning program conducted by the Aviation Service Department of J University, a four-year university in the Chungcheong region. ANOVA (one-way analysis of variance) is conducted to analyze differences in perceptions of field learning properties, learning satisfaction, academic self-efficacy, and intention to continue studying. Additionally, text mining is conducted using 'Voyant Tools' to analyze students' field trip logs regarding field trip learning program activities. I hope that the results will be used as evidence to build an efficient and systematic learning strategy for operating field learning programs.

본 연구에서는 시간제 등록 학생들의 실습현장에서 경험하고 학습하는 여러 구성 요인 중 어떠한 요인들이 실습성과에 영향을 미치는지를 탐구하여, 사회복지교과목 중 중요한 위치를 차지하고 있는 실습의 방향을 제시하고자 한다. 연구결과 첫째, 실습기관의 종류에 따른 실습지도자 평가와 실습기관 평가 및 실습성과의 차이를 분석한 결과 유의미한 차이를 보이지 않았다. 둘째, 실습성과에 영향을 미치는 요인을 분석한 회귀분석 결과, 실습지도자 평가와 실습기관 평가요인의 영향력을 확인할 수 있었다. 개선방안으로 사회복지법인 이외의 실습지도자에게 지속적인 교육훈련의 기회가 주어져야 할 것이다. 실습기관에서는 실습생을 적절히 지도할 수 있는 체계적인 교육프로그램의 준비가 필요하다. 사회복지현장 실습을 수행하고 있는 기관간의 유기적인 협력체계로 지역내 공동실습을 계획하는 것도 바람직한 대안이다.

This study was conducted after implementing the field environmental education for fifth graders with the teaching-teaming plan applied to the field education and was based on the analysis of environment-related education for the fifth graders. A total of 64 elementary students, 32 in the experimental group and 342 in the control group, were involved in this study. The study used the instrument consisting of 36 Likert-type questions on attitudes toward environment. After going over the influences of the field environmental education program on the students, we found out the positive development in the pre-test and post-test, concerning all environmental themes, especially in the field of protection of animals, environmental pollution, and environment in general.

In the suburbs near the capital area in Korea, many apartment house complexes are dotted that encircled by field. These apartment house complexes encircled by field, have not park and are abutting on the field, unlike large scale new town. This study is aimed to clear the characteristic of field around these apartment house complexes, consists in development the suburbs near the capital area. As a method of study we conducted greenery evaluation from view of Inhabitant by questionnaire survey. We concluded as follows: inhabitants attach importance to the nature around apartment house complex when move into that; inhabitants are satisfied and feel nature about the field; inhabitants tend to take field as a sight; inhabitants need low-rise development for harmony with field.

It has been known that D.C. breakdown Voltage is lower than A.C. breakdown Voltage in insulatingoil, but there are still many unvivid points at electric conduction in breakdown or under of high electric field. This study measured the electric current-electric field characteristics (I-E characteristics) and the breakdown Voltage under of D.C. electric field of insulating oil using the system of electrodes that are near the Uniform electric field with a result. I can study, electric conduction in area of high electric field depends upon the Schottky effect. The liquidity of breakdown electric field takes place by the local concentration of electric field. The longer gap is and the more electric current is the more breakdown Voltage decreased. There are not almost the change of electric current-electric field characteristics by materials of electrode.

The purpose of this study is to develop the educational program of consumer adviser. The educational program proposed in previous study is consisted of the acquisition of 5 require and 2 optional subjects, and field education. For this, based on the role and capacity of consumer adviser we explain in detail the contents of required subjects. And we confirm the necessity and significance of field education. Finally we investigate the confirm the necessity and significance of field education. Finally we investigate the contents of field education and suggest the system and course of desirable field education through case study of several universities.

Power semiconductor devices have been the major backbone for high-power electronic devices. One of important parameters in view of power semiconductor devices often characterize with a high breakdown voltage. Therefore, many efforts have been made, since the development of the Insulated Gate Bipolar Transistor (IGBT), toward having higher level of breakdown voltage, whereby the typical design thereof is focused on the structure using the field ring. In this study, in an attempt to make up more optimized field-ring structure, the characteristics of the field ring were investigated with the use of theoretical arithmetic model and methodologically the design of experiments (DOE). In addition, the IGBT having the field-ring structure was designed via simulation based on the finding from the above, the result of which was also analyzed. Lastly, the current study described the trench field-ring structure taking advantages of trench-etching process having the improved field-ring structure, not as simple as the conventional one. As a result of the simulation, it was found that the improved trench field-ring structure leads to more desirable voltage divider than relying on the conventional field-ring structure.

In social welfare arena field practicum has been an essential instrument and method for social work students to get socialized to the social work professional. However, to whom involve in the actual field practicum-universities(or colleges), institutes - have some difficulties. On the base of community welfare is a clinical approach in this times. To strengthen community welfare policy, the beginning of community welfare committee is such a good opportunity to tackle the problems of the field practicum. This study suggest that the problem of the field training are 1) a guidance of an individual social work institute, 2) the lack of social work institute, 3) the absence of the trainee's sense of values, 4) the bad conditions of the field practicum for social work students in undergraduate courses at the university(or college), and 5) the lack of professionalism for supervisors. This study makes the following social work suggestions to vitalize field practicum in community welfare. It is more likely important to 1) make the law of the field practicum for undergraduate social work courses, 2) make the coordinated programs of the field practicum for undergraduate social work course in community welfare, 3) enlarge the opportunity that a field specialist take further education, 4) support and carry of supervisor reeducation, 5) make the program development of trainee's personal experiences in social work values, and 6) social work professors make a practice in the social work field.

Turbomolecular pump (TMP) is widely used to obtain and maintain high vacuum by spinning turbine rotors to migrate gas molecules to the exhaust of the pump. However, performance of the TMP has not been well observed when it is influenced by strong magnetic field. Such study may give useful information about magnetic field tolerance of TMP, development of magnetic shielding technique for key components of TMP, etc. For this purpose, magnetic field induced by a circular current source was firstly designed and investigated. Using spherical coordinates and vector potential, magnetic field throughout the space including axis of rotation was calculated. Due to the rotational symmetry of the circular current source, induced magnetic field is azimuthally symmetric and, thus, is analyzed by radial and polar components of the magnetic fields. In order to enhance the numerical accuracy for the calculation, magnetic field was expressed by complete elliptic integrals of first and second kinds. According to the calculation, when 1 A of DC-current passes through a 1 turned circular wire with 50 cm of diameter, overall magnitude of the inducedmagnetic field was about 0.02 Gauss, which was used to the determination of the current and the number of turns of wires to fabricate the coil for the study on the magnetic field tolerance of TMP.
