When an interplanetary (IP) shock passes over the Earth's magnetosphere, the geosynchronous magnetic field strength near the noon is always enhanced, while the geosynchronous magnetic field near the midnight decreases or increases. In order to understand what determines the positive or negative magnetic field response at nightside geosynchronous orbit to sudden increases in the solar wind dynamic pressure, we have examined 120 IP shock-associated sudden commencements (SC) using magnetic field data from the GOES spacecraft near the midnight (MLT = 2200~0200) and found the following magnetic field perturbation characteristics. (1) There is a strong seasonal dependence of geosynchronous magnetic field perturbations during the passage of IP shocks. That is, the SC-associated geosynchronous magnetic field near the midnight increases (a positive response) in summer and decreases (a negative response) in winter. (2) These field perturbations are dominated by the radial magnetic field component rather than the north-south magnetic field component at nightside geosynchronous orbit. (3) The magnetic elevation angles corresponding to positive and negative responses decrease and increase, respectively. These field perturbation properties can be explained by the location of the cross-tail current enhancement during SC interval with respect to geosynchronous spacecraft position.

The purpose of this thesis is to study the optimal arrangement of aircraft instrument panels through the human factors approach. Human factors engineering is the process of effectively fitting the human component to the machine component in any man-machine system. The human factors. are especially important to an aircraft pilot who must constantly shift his attention between the instrument panel within the cockpit and the surrounding area of the aircraft. The preliminary part of this study is to find the general patterns of the Korean pilot's eye movements during their various flying maneuvers, and which instruments require the most attention while in flight. It is assumed that all pilots have a general pattern of eye movement when observing the aircraft instrument panel and that an optimum arrangement would be to minimize the eye travel distance between instruments. In this thesis the arrangements of instruments is taken to be the independent variable and the eye travel distance between instruments the dependent variable. la order to compile the information necessary for this study, sixty Korean Air Force pilots were interviewed and requested to complete information forms. These information forms listed various flying maneuvers and listed each instrument used on the instrument panel. The compilation of the information on these completed forms listed the instruments most frequently used by the pilots. The second part of this study was to determine the optimum instrument arrangement. It was necessary to study the various number of possible arrangements of instruments depending upon the number of instruments involved. Therefore, these instruments are grouped by two major functions, The flight instruments were subdivided into three groups, and the engineering instruments were subdivided into six groups. With this subdivision we arrive at the possible number of arrangements of 4,320. Through the simulation method, total eye travel distance for each of these 4,320 arrangements is calculated and the arrangement which appears to be of optimum distance between the most frequently used aircraft instruments is determined. The results of this study indicate that the optimum distance between instruments would be 33,028cm and that the corresponding distance of the instrument panel now being used is 34,288cm. Therefore, an increased efficiency of $3.8\%$ would be realized if the existing aircraft instrument panel were re-arranged according to layout proposed in this thesis.

Configuration management plays a key role in systems engineering process for any project from earlier stage of development. It consists of five major activities, ie., configuration management planing, configuration identification, configuration control, configuration status accounting and configuration verification and audit, and is essential to control system design, development and operation throughout entire life cycle of the system development. And it is directly associated with other part of systems engineering management process, ie., technical data management which provides traceability of important decisions and changes during development. In this paper, we describe how to apply CASE(Computer-aided Systems Engineering) tool-Cradle for the configuration management to achieve effectiveness of Technical Management process.

Variable selection algorithm for partial least square regression using penalty function is proposed. We use the fact that usual partial least square regression problem can be expressed as a maximization problem with appropriate constraints and we will add penalty function to this maximization problem. Then simulated annealing algorithm can be used in searching for optimal solutions of above maximization problem with penalty functions added. The HARD penalty function would be suggested as the best in several aspects. Illustrations with real and simulated examples are provided.

‘유관순학’ 강좌를 통한 유관순 열사의 역사적 위치와 사상적 계승 - 수강 전후 인식 변화를 중심으로

박종선(Jong Sun Park), 박창원(Chang Won Park) 백석대학교 유관순연구소 2025 유관순 연구 Vol.30 No.1

본 연구는 한국 독립운동의 대표적인 인물이자 비폭력 저항의 상징인 유관순 열사의 삶과 사상을 중심으로, ‘유관순학’ 강좌의 교육적 효과를 분석하고 청년 세대의 역사 인식과 시민 의식 제고에 기여하는 바를 실증적으로 고찰하고자 하였다. 유관순은 17세의 나이에 식민 권력에 맞서 비폭력 저항을 실천한 인물로서, 단순한 과거의 영웅을 넘어 현대교육 현장에서 활용 가능한 인문학적 콘텐츠로 재조명될 수 있는 인물이다. 이를 위해 본 연구는 ‘비폭력 저항’, ‘여성 인권’, ‘종교 윤리’, ‘청년리더십’이라는 네 가지 핵심 키워드를 중심으로 유관순의 생애를 재해석하고, 평화 및 인권 교육의 플랫폼으로서 ‘유관순학’ 강좌의 확장가능성을 모색하였다. 연구는 백석문화대학교 생명윤리위원회의 심의를 거쳐(승인번호: 제2-7008132-A-N-01호. 25-01), 2025년 3월부터 6월까지 충남 천안시에 소재한 B대학교 재학생 68명을 대상으로 유관순학 수강 전후의 설문조사를 실시하고, 이를 분석하였다. 연구 결과는 다음과 같다. 첫째, 수강 이후 학생들의 역사에 대한 흥미와 학습 동기, 그리고 독립운동 관련 지식이 통계적으로 유의미하게 향상되었다. 둘째, 유관순의 종교적 신념과 독립운동 간의 연계성에 대한 이해가 심화되었으며, 해당 강좌의 교육적 필요성에 대한 공감도 역시 크게 증가하였다. 셋째, 유관순의 역사적 상징성에 대한 인식은 ‘희생’과 ‘애국’이라는 개념을 중심으로 강화되었고, 일제의 식민지 통치제도에 대한 이해 역시 확장되었다. 넷째, 3·1운동과 종교 간의 관계에 대한 인식이 다층적으로 제고되었으며, 유관순의 옥중 투쟁에 대한 이해도 긍정적으로 유지되었다. 다섯째, 3·1운동의 세계사적 파급효과와 여성 독립운동가의 역할에 대한 인식 역시 유의미하게 향상되었으나, 식민지 교육정책과 구국계몽운동에 대한 이해는 상대적으로 낮은 상승폭을 보였다. 종합적으로 볼 때, 유관순학 강좌는 청년 세대의 역사적 감수성과 시민적 책임 의식을 함양하는 데 효과적인 인물 중심 역사교육 모델로 기능하고 있으며, 나아가 평화교육의 현대적 플랫폼으로서 지속적인 확장 가능성을 내포하고 있다. 이러한 교육적 시도는 한국 독립운동의 세계사적 의미를 재조명하는 동시에, 지속 가능한 평화 공동체 형성을 위한 학술적 기반을 마련하는 데 중요한 의의를 지닌다. This study aims to empirically examine the educational impact of the course “Yu Gwan-sun Studies,” which focuses on the life and philosophy of Yu Gwan-sun, a leading figure in Korea’s independence movement and a symbol of nonviolent resistance. Yu Gwan-sun, who practiced nonviolent protest against colonial rule at the age of 17, is reinterpreted not merely as a historical figure but as a valuable source of humanistic content applicable in contemporary education. To this end, the study reinterprets her life through four core keywords-nonviolent resistance, women’s rights, religious ethics, and youth leadership-and explores the potential of the “Yu Gwan-sun Studies” course as a platform for peace and human rights education. The research was conducted in accordance with the ethical guidelines of Baekseok Culture University’s Institutional Review Board (IRB No. 2-7008132- A-N-01. 25-01). From March to June 2025, a pre- and post-course survey was administered to 68 undergraduate students enrolled in the course at a university located in Cheonan, Chungnam Province. The findings are as follows: First, students’ interest in history, motivation to learn, and knowledge of the independence movement showed statistically significant improvement after taking the course. Second, students demonstrated an increased understanding of Yu Gwan-sun’s religious convictions and their connection to the independence movement, along with a greater appreciation for the necessity of such educational programs. Third, perceptions of Yu Gwan-sun’s symbolic meaning were strengthened, particularly around themes of “sacrifice” and “patriotism,” and students’ understanding of colonial governance systems also expanded. Fourth, awareness of the role of religion in the March 1st Movement—particularly Christianity, Daejonggyo, and Buddhism-deepened, and perceptions of Yu’s imprisonment and suffering remained positive. Fifth, recognition of the global impact of the March 1st Movement and the role of female independence activists improved significantly, although understanding of colonial educational policies and the Enlightenment movement showed a relatively modest increase. Overall, the “Yu Gwan-sun Studies” course functions as an effective educational model that fosters students’ historical sensitivity and civic responsibility. It contributes to identity formation, value-based education, and critical thinking through a biographical approach to history. Furthermore, the course demonstrates potential as a modern platform for peace education. Ultimately, this initiative offers meaningful academic value by reilluminating the global significance of Korea’s independence movement and laying a foundation for building a sustainable culture of peace.

勞組法では使用者の不利益取扱、支配介入などの一定な行爲を不當勞動行爲としてこれを禁止しており,このような使用者の禁止行爲に對して勞動委員會による救濟手續を規定している。韓國と日本の不當勞動行爲救濟制度の運營は法理及び救濟機關がほぼ同一である。しかし運用上においては救濟對象、申迂み期間及び事件處理、事實認定に對する態度など多い部分において差があって結果的に不當勞動行爲認定率において特に差を現わしている。ここでは實質的に韓·日兩國の中勞委判定事例を分析·檢討して見ることで不當勞動行爲救濟制度に對する法理解釋及び運用上のどんな相異点があって兩國不當勞動行爲の決定と認定に差をもたらすかに焦点を置いて比較·檢討しようとするのである。不當勞動行爲に對する韓·日兩國の中勞委事例を通じて比較法的に分析·檢討した後、兩國の比較を通じて勞動委員會判定及び運用上の問題点を改善することができる時事点を見つけようとしている。⑴ 日本は不當勞動行爲意思を直接的に明示して不當勞動行爲成立のための要件にしていない。 すなわち使用者の行爲や客觀的な情況や證據から使用者の不當勞動行爲意思を解釋して推定する方式で不當勞動行爲意思を間接的に認めている。⑵ 不當勞動行爲事實の立證責任は申請人において具體的に立證することができない場合、不當勞動行爲成立主張は受け入れることができないという固定觀念から脫して使用者に一定部門立證責任を付與するとか、勞動委員會が職權證據調査を通じて立證を補う制度が必要である。⑶ 不利益取扱いを認める場合支配·介入まで認めるのが望ましい。不利益取り扱いは組合活動に對する不安感造成及び心理的萎縮、組合脫退及び消極的組合活動をもたらして組織力弱化という支配·介入まで認められることができるからである。⑷ 組合員でいることを理由でも不當勞動行爲成立要件になることができる。結局組合員と言うのは實はでなく不利益取扱い受ける他の事由がない場合と勤勞者の精神的被害が招來されることができる狀況で精神上の不利益被害までも不當勞動行爲で手廣く認めるのが望ましい。

Purpose : This study is a research of awareness of hospital marketing factors on an outpatient and an inpatient who use general hospitals in one area and is tried to develop a program to provide some basic materials for the education of Hospital Management. Method : To achieve this purpose, we carried out investigation using a questionnaire on 100 inpatients in K general hospital and 104 inpatients in J general hospital which are the second medical institution located in Jinju from July 2nd in 2003 to July 12th in 2003. In the tests for reliability and validity of this study's study tools, the reliability of whole study tools was Cronbach's Alpha=.9213 and the reliabilities by factors were. 8723 in service strategy, .8788 in price strategy, .7957 circulation strategy, and .7821 promotion strategy. The collected data from this study were analyzed using SPSS 10.0 for Windows. And we divided the subjects into two groups through the K-means Clustering Analysis according to the awareness that the subjects of this study had about hospital service : A group of low degree of awareness on service and a group of high degree of awareness on service. The subject’s general characteristics was analyzed using Frequency and Percentage, the difference of awareness on each service area according to general characteristics, awareness group, and curative form was analyzed by enforcing Independent-Samples T Test and ANOVA, and the correlation between each hospital service areas was analyzed using Pearson Correlation Coefficient. In addition, Multiple Response was used for analyzing the reason to select the hospital and hospital image, respectively. Result : 1. We named the groups by the subject's level of awareness as awareness group. The group of low degree of awareness was composed of 67 patients(32.8%) and the group of high degree of awareness was composed of 137 patients(67.2%). Furthermore, it was appeared that these groups had a significant difference by job(p<.05), whereas they didn’t have any significant difference by sex, age, a school career, marriage or not marriage, and a curative means among the subject's general characteristics 2. In the study of awareness of hospital service according to the subject's general characteristics of this study, it was appeared that they were comparatively satisfied with the service as a whole average 3.32. It was appeared that the satisfaction by the details were average 3.29 in service strategy, average 2.96 in price strategy, average 3.72 in circulation strategy, and average 3.29 in promotion strategy. 3. The results comparing the difference of awareness level by hospital service area according to the subject's general characteristics of this study are as follows : the variables which showed statistically significant difference with service and price strategies were a school career and job and the variable which showed statistically significant difference with circulation strategy was sex. According to the awareness group, it was reported that the group of high degree of awareness had higher satisfaction than the group of low degree of awareness statistically significantly in all area of marketing mix(p<.001). And according to the curative means, inpatients showed higher degree of satisfaction than outpatients in all of the areas except a circulation area, but it was not statistically significant. 4. As a result of correlation analysis between each variables related to hospital service, the highest statistically significant correlation was investigated between service strategy and promotion strategy as r=.624, and then very high positive linear correlation was appeared between service strategy and circulation strategy as r=.605(P<.001). 5. In the study of the reason to select the hospital, the answer that 4the traffic coming to hospital is convenient’ was highest and next, ‘because of other people’s saying or having many excellent doctors’, ‘the doctors in this hospital treat a disease well’ in sequence. 6. In the question about hospital image, the answer that 'the staffs of this hospital are kind’ was highest, and then ‘the traffic coming to hospital is convenient, the doctors or nurses in this hospital explain a disease well’ in sequence, and the answer that ‘this hospital is the most reliable hospital’ was appeared as the lowest. Conclusion : A medical institution should consider the patient's awareness of hospital service

거대한 내수시장과 저임금 노동시장을 장점으로 한 중국은 한국의 제 1위의 투자국이자 교역국 이다. 그러나 안정적 고도성장, 균형발전, 조화사회 건설 및 개혁개방 심화를 목표로 중국 정부가 추진 중인 11·5 규획은 외자기업의 수익률 감소로 이어질 수 있다는 전망이다. 이에 한국기업의 대중 투자동향 및 현황을 살펴보고 이번 11·5 규획이 대 중 투자환경에 어떤 변화와 영향을 미칠 것인가를 분석하고 변화에 따른 대응 방안 및 성공적인 중국투자 방안을 제시한다. China, which has a great advantage of having a huge domestic market and a labor market with low wages, is Korea`s number one investing and trading country. However, the 11th 5 year program(11.5 program) which the government of China is promoting for stable high growth, well-balanced development, the construction of a harmonic society and also for the deepening of reformation and opening, could lead to a decrease on the earning rate of a foreign capital enterprise. For this reason, we should observe the popular investing trend and the present condition of Korea`s enterprise, and analyse how the 11th 5 year program is going to effect China`s investing environment. We should also present a countermeasure and a successful investment program in China.
