Radish is familiar vegetable and has long been cultivated in Korea owing to appropriate climate. In domestic market, radish that has particular texture is prefered, which is associated with physicochemical properties of it. In this study, amount of major components of radishwas determined and analyzed in relation with physicochemical property which affects texture of radish. Twenty two radish cultivars were analyzed in relation with cutting force, starch/cellulose, total phenolic compounds and color. Radish showed 3.63±0.31 kg cutting force, had 3.75±0.39 g starch per 100 g (dry basis), and had 181.43±44.11 mg total phenolic compounds per 100g (dry basis). Sun drying radish had 80.86±2.18 Hunter L value, 1.74±0.66 a value, 24.70±1.42 b value. Hot air drying radish had 85.51±1.27 Hunter L value, -1.15±0.50 a value, 20.30±1.06 b value. No relationship was found between the cutting force and the starch content, but the cellulose contents showed a positive relationship with the cutting force. In the relationship between color and total phenolic compounds, if contents of total phenolic compounds increases, brightness decreases and a value increases; however, coefficient of correlation counts on drying methods. Analysis of tasty substances and studies of storages are necessary to analyze in relations between quality of radish and physicochemical properties.

This paper deals with analysis of thermal characteristic and power loss of induction motors for machine tool spindle considering load condition. A trend in high-speed/high-performance machining technology involves targeting a spindle that can perform high-speed and high-power machining operations. For such applications, the spindle motor should be able to provide the power needed for cutting even when running at high rotational speeds.Because the specified applications incur a wide variety of cutting load conditions, the machine efficiency and temperature rise in the motor are of great interest to machine tool manufacturers. Induction motors are the most common type of motors used in machine tools. High-performance induction motors with variable-voltage, variable-frequency (VVVF) inverters are often applied to machine tool spindles that operate at lower speeds and lower output powers than the motor’s rated values Meanwhile, the temperature rise in an induction motor critically affects the failure rate and service life. In particular, the temperature rise of the stator and rotor resulting from a significant stator core loss, copper loss, or rotor loss, as caused by variations in the current, could adversely affect the torque characteristics and durability. Moreover, the temperature rise affects the fabrication quality and cutting error in ultra-precision rotational machine tools. To reduce the fabrication and cutting errors caused by thermal strain in a machine tool spindle, deals with the following study. Firstly, paper present design theory the characteristics of the induction motor. From the result, torque-speed characteristic curve in Catalog is similar to induction motor by design. The inverse design of general induction motors for machine tool spindle has been performed by design principles. This paper analyzed the equivalent circuit of the induction motor. Characteristics of induction motors considering VVVF inverter were analyzed. Secondly, paper is adopted the experimental model that 0.4kW class general induction motor. This paper presents an investigation of power loss distribution in an induction motor for machine tool spindles considering the effect of loading. This paper employed the design of experiment (DOE) and response surface methodology (RSM) techniques for power loss analysis. To develop a second-order fitted model of the power loss distribution, the central composite design (CCD) technique was used. CCD is frequently used for fitting a second-order response model. By using commercial finite element analysis software (Ansys Maxwell 2D v.16), the steady-state power losses are calculated in the constant-torque region of the induction motor. Finally, modeling for thermal analysis was performed using Motor-CAD v.7.2.5 software (Motor Design Ltd.). This paper analyzed the main parameters and thermal resistance. The transient thermal characteristics of the induction motor are calculated by applying the equivalent thermal resistance model from Motor-CAD v.7.2.5 software. And to validate the theoretical characteristic analysis results, temperature measurements were performed using a commercial induction motor. This Paper also implemented a measurement test setup and confirmed that the experimental results were in good agreement with the results of the proposed simulation.

성기현 韓國航空大學校 2018 국내박사

급변하는 유통환경과 소비자의 소비 행동 변화, 그에 따른 소비자의 브랜드 경험이 중요시되면서 기업들은 다양한 경험마케팅을 도입하고 있으며, 플래그십 스토어는 경험마케팅의 대표적인 공간이라 할 수 있다. 경험마케팅에 대한 연구는 많이 진행되어왔지만, 경험마케팅이 브랜드 태도와 구매의도에 영향을 미치는 그 과정을 소비자 개인의 해석수준 관점에서 설명한 연구는 부족한 실정이다. 이에 본 연구에서는 플래그십 스토어에서의 브랜드 경험이 개인의 상황(심리적 거리), 개인의 성향(행동정체성), 개인의 사전경험(브랜드 친숙성)의 수준과 정도에 따라 브랜드 태도와 구매의도에 긍정적인 조절효과를 미치는지에 대해 알아보고자 한다. 이에 본 논문의 실증분석은 플래그십 스토어의 브랜드 경험(감각, 감성, 행동, 인지)에 대하여 심리적 거리, 행동정체성, 브랜드 친숙성을 조절변수로 사용하여 브랜드 태도와 구매의도에 영향관계를 구조방정식을 통해 검증하였다. 첫 번째, 구조방정식 모형의 가설검증 결과를 종합적으로 보면, ‘플래그십 스토어의 브랜드 경험은 브랜드 태도에 긍정적인 영향을 미칠 것이다.‘ 라는 가설 1은 ‘플래그십 스토어의 브랜드 경험의 구성요소 중 인지적 경험은 브랜드 태도에 긍정적인 영향을 미칠 것이다.’ 라는 가설 1-4만 기각되었으며, 나머지 가설 1-1, 1-2, 1-3은 채택되었다. 또한, ‘방문고객의 브랜드 태도가 높아질수록 구매의도에 긍정적인 영향을 미칠 것이다.’ 라는 가설 2도 채택되었다. 즉, 브랜드 경험요소 중 감각적 경험, 감성적 경험, 행동적 경험이 브랜드 태도에 유의한 영향을 미치는 것으로 나타났으며, 브랜드 태도가 높아질수록 구매의도에 긍정적인 영향을 미치는 것으로 나타났다. 두 번째, 심리적 거리에 대한 조절효과의 가설 검증 결과를 종합적으로 보면, ‘플래그십 스토어의 브랜드 경험이 브랜드 태도에 미치는 영향은 심리적 거리가 가까울수록 긍정적인 조절 효과가 있을 것이다.’ 라는 가설 3은 ‘플래그십 스토어의 브랜드 경험의 구성요소 중 행동적 경험이 브랜드 태도에 미치는 영향은 심리적 거리가 가까울수록 긍정적인 조절 효과가 있을 것이다.’ 라는 가설 3-3에서만 채택되었으며, 나머지 가설 3-1, 3-2, 3-4에서는 기각되었다. 즉, 심리적 거리에 따른 긍정적인 조절효과는 브랜드 경험요소 중 행동적 경험에서만 유의한 것으로 나타났다. 세 번째, 행동정체성에 대한 조절효과의 가설 검증 결과를 종합적으로 보면, ‘플래그십 스토어의 브랜드 경험이 브랜드 태도에 미치는 영향은 행동정체성이 낮을수록 긍정적인 조절 효과가 있을 것이다.’ 라는 가설 4는 ‘플래그십 스토어의 브랜드 경험의 구성요소 중 감성적 경험이 브랜드 태도에 미치는 영향은 행동정체성이 낮을수록 긍정적인 조절 효과가 있을 것이다.’ 라는 가설 4-2만 기각되었으며, 가설 4-1, 4-3, 4-4는 채택되었다. 즉, 행동정체성에 따른 긍정적인 조절효과는 브랜드 경험요소 중 감각적 경험, 행동적 경험, 인지적 경험에서 유의한 것으로 나타났다. 네 번째, 브랜드 친숙성에 대한 조절효과의 가설 검증 결과를 종합적으로 보면, ‘플래그십 스토어의 브랜드 경험이 브랜드 태도에 미치는 영향은 브랜드 친숙성이 높을수록 긍정적인 조절 효과가 있을 것이다.’ 라는 가설 5는 ‘플래그십 스토어의 브랜드 경험의 구성요소 중 인지적 경험이 브랜드 태도에 미치는 영향은 브랜드 친숙성이 높을수록 긍정적인 조절 효과가 있을 것이다.’ 라는 가설 5-4만 기각되었으며, 가설 5-1, 5-2, 5-3은 채택되었다. 즉, 브랜드 친숙성에 따른 긍정적인 조절효과는 브랜드 경험요소 중 감각적 경험, 감성적 경험, 행동적 경험에서 유의한 것으로 나타났다. 다섯 번째, 조절효과의 검증 결과에서 인지적 경험이 브랜드 태도에 미치는 영향은 심리적 거리를 조절변수로 이용한 가설 H3-4와 브랜드 친숙성을 조절변수로 이용한 가설 H5-4에서는 기각되었고, 행동정체성을 조절변수로 이용한 가설 H4-4에서만 채택되었다. 즉, 인지적 경험이 브랜드 태도에 미치는 영향은 조절변수 중 행동정체성에서만 유의한 것으로 나타났다. 여섯 번째, 조절효과의 검증 결과에서 감성적 경험이 브랜드 태도에 미치는 영향은 심리적 거리를 조절변수로 이용한 가설 H3-2와 행동정체성을 조절변수로 이용한 가설 H4-2에서는 기각되었고, 브랜드 친숙성을 조절변수로 이용한 가설 H5-2에서만 채택되었다. 즉, 감성적 경험이 브랜드 태도에 미치는 영향은 조절변수 중 브랜드 친숙성에서만 유의한 것으로 나타났다. 본 연구에서 기업의 마케팅 활동이 소비자 개인의 해석수준에 따라 브랜드 태도에 어떠한 영향을 미치는지에 대해 연구하였다. 이러한 연구결과를 통해서 기업이 마케팅 활동을 전개해나가는 데 있어 소비자의 행동에 영향을 미치는 개인의 해석수준과 플래그십 스토어의 다양한 경험에 대한 자극, 공간 구성과의 매칭효과 등 마케팅 전략에 대해 시사점을 제시하고 있다.

요한문헌의 '서로 사랑' 명령의 성격 : 종파적인가 보편적인가

성기현 평택대학교 2024 국내박사

Interpreters, often citing John 13:34-35 and 15:12, 17, have questioned the nature and scope of Johannine love. Critics argue that Jesus instructed John’s community to love only one another, excluding neighbors, enemies, or the broader world. This has led to characterizing the command as sectarian, exclusive, and of low standard. However, many Johannine scholars challenge this notion, asserting that the love command extends beyond the sect or community. This thesis, guided by R. B. Hays’ methodology for studying New Testament ethics, aims to explore the mutual love texts in John’s writings. It addresses the contentious question of whether the command to love 204 ‘one another’ is sectarian, narrow-minded, or of low standard. Chapter I outlines the problems, research history, limitations, procedures, and justification for the study. Recognizing the need for a more comprehensive investigation, the chapter emphasizes that the “love for one another” encompasses universal love, extending even to enemies. Chapter II introduces Hays’ methodology, leading to descriptive, synthetic, hermeneutical, and pragmatic tasks. Descriptive exegesis requires a focused reading of selected texts. The synthetic task examines the theme across the New Testament, considering Community, Cross, and New Creation. The hermeneutical task reinterprets contents in light of various factors. The pragmatic task explores how to apply these teachings in the life of a community. Chapter III delves into the nature of the “love for one another” command through exegetical investigation. It argues against sectarianism, asserting that Christian love extends beyond the community to include neighbors, enemies, and everyone. Chapter IV studies texts on “love for one another” throughout the New Testament. Community, Cross, and New Creation are consistently referenced, depicting a universal love encompassing neighbors and enemies. The difficulty of executing this command is acknowledged, tied to the sacrificial nature of going the way of the cross, reserved for those who experience renewal through the Holy Spirit. Chapter V addresses hermeneutical and pragmatic tasks. It clarifies that the rules, principles, paradigms, and symbolic world of “love for each other” are evident in Johannine writings, demonstrating it is not a sectarian, narrow, or low-level command. While tradition alone may not 205 decisively determine the universality of love, reason and experience suggest that reciprocal love is a universal command. The church community is thereby called to practice the “love for one another” command, inclusive of enemies and everyone. In conclusion, this dissertation refutes claims of the Johannine Corpus’s love command being sectarian, narrow, or inward-looking, positing it as a higher standard and more universal than that in the Synoptic Gospels. Through precise exegetical study, it contributes to establishing the nature of Johannine Christians as an open, non-sectarian community.

본 연구는 경상남도 119구급상황관리센터가 주관한 실무 중심의 특별교육 프로그램에 참여한 구급대원을 대상으로, 교육 만족도 및 체감 효과에 영향을 미치는 요인을 양적 및 질적 접근을 통해 종합적으로 분석하였다. 본 연구의 목적은 응급구조 현장 실무자 대상의 교육이 실제로 얼마나 효과적으로 작용하고 있는지를 평가하고, 실무 중심 응급교육 체계 수립을 위한 실질적인 개선 방향을 도출하는 데 있다. 양적 분석에서는 구조화된 설문지를 바탕으로 먼저 기초통계 분석(빈도, 평균, 백분율, 표준편차)을 실시하여 참여자의 일반적 특성과 응답 경향을 확인하였다. 그리고 다중회귀분석 결과에서는 회귀모형의 설명력이 R²=0.722로 나타났으며 추천의향(β=0.203 p<.01), 업무효율성(β=0.184 p<.05), 자신감 향상(β=0.113 p<.05)이 교육 만족도에 통계적으로 유의미한 영향을 미치는 변수로 확인되었다. 한편, ‘상호 이해도’(β = 0.153, p = 0.055)는 유의수준 0.05에서 통계적으로 유의하지는 않았으나, 교육 만족도에 일정 수준의 영향력을 갖는 경향이 있는 변수로 나타났다. 특히 추천의향은 가장 높은 영향력을 보여 교육을 다른 동료에게 추천하고자 하는 태도가 전반적인 교육 만족도에 직접적으로 연관됨을 보여준다. 질적 분석은 설문지 내 개방형 문항에 대한 응답 93건을 대상으로 해석학적 현상학 분석(Interpretative Phenomenological Analysis) IPA를 수행하였다. 분석 결과 일반적 교육 만족감 31건(33.3%), 체험 중심 학습의 효과성 30건( 32.3%), 조직 통합과 상호 이해 24건(25.8%), 업무 프로세스 이해 8건(8.6%) 등 네 가지 주요 하위 주제가 도출되었다. 특히 소방사 및 30대 구급대원들은 체험 중심 학습을 가장 유의미한 교육 요소로 평가하였으며 이는 현장 상황과 유사한 실습 환경이 학습의 효용성을 높였음을 반영한다. 이러한 혼합연구 결과는 교육만족도 향상을 위해 교육내용의 실무 연계성 강화, 상호이해 제고, 자신감 향상 등과 같은 제도적, 심리적 요소에 의해 결정되며, 대상자의 연령, 성별, 계급 등 다양한 특성을 고려한 교육 설계가 요구됨을 시사한다. 본 연구는 현장 적용이 가능한 주제별 교육 프로그램을 마련하고, 부서 간 협업 이해 증진, 반복 실습과 피드백 체계의 강화 등 응급교육 정책의 질적 향상 노력을 위한 실증적 근거를 제공하며, 향후에는 반복 측정 및 장기 추적 설계를 통해 교육의 지속성과 실제 업무성과와의 연계성을 분석하는 후속 연구가 필요할 것이다. This study comprehensively analyzed factors influencing satisfaction and perceived effectiveness of an applied emergency education program, led by the Gyeongsangnam-do 119 Emergency Medical Dispatch Center, using both quantitative and qualitative approaches. The purpose of this research was to evaluate the actual effectiveness of field-oriented education for emergency medical personnel and to derive practical directions for improving the emergency education system. Qualitative analysis was conducted using Interpretative Phenomenological Analysis (IPA) on 93 open-ended responses from a structured questionnaire. Four key subthemes emerged: general satisfaction with education (33.3%), effectiveness of experience-based learning (32.3%), organizational integration and mutual understanding (25.8%), and understanding of work processes (8.6%). Particularly, firefighters and paramedics in their 30s evaluated experience-based learning as the most meaningful component, indicating that practice in environments similar to real-life situations enhanced learning effectiveness. The mixed-methods findings suggest that institutional and psychological factors—such as practical relevance of content, promotion of mutual understanding, and increased confidence—are crucial to improving training satisfaction. These results also highlight the necessity of designing training programs that account for diverse participant characteristics, such as age, gender, and rank. This study provides empirical evidence for the development of applicable, topic-specific training programs, fostering interdepartmental collaboration, and enhancing feedback and repetition systems. Future research should include longitudinal and repeated measures designs to assess the continuity of educational effects and their linkage to actual work performance. Quantitatively, descriptive statistics (frequency, mean, percentage, standard deviation) were used to assess participant characteristics and response tendencies. A multiple regression analysis showed that the model's explanatory power was R² = 0.722. Recommendation intention (β = 0.203, p < .01), work efficiency (β = 0.184, p < .05), and confidence improvement (β = 0.113, p < .05) were statistically significant predictors of educational satisfaction. Although mutual understanding (β = 0.153, p = 0.055) did not reach statistical significance at the 0.05 level, it showed a trend toward influence. Notably, recommendation intention had the strongest impact, indicating that the willingness to recommend the training to colleagues is directly related to overall educational satisfaction.

The criminal investigations are getting more difficult as the crimes are dramatically increasing and their ways are getting more elaborate these days. The ways of the criminal investigations also need epochal changes because new types of crimes with the change of the times are increasing and a national sense of human rights is rising. First of all, it is an urgent fact that we should specialize the police investigation system to cope with such changes of the criminal aspects. In the first place, we should restructure the investigation system for efficiency and develop new investigation techniques while we need to call in the best brains. There are three main aspects below for the specialization of the police investigation. First, the police needs investigation rights of its own way. Only the prosecution is the president of investigation although the police deal with 97% of the crimes in Korea which is not reasonable. The efficiency of the police investigation is decreasing and the police become demoralized for sure so the people can be victims. Second, we should separate the administrative police and the judicial police. In fact, the police is under the command of the prosecution covering whole range of the police performance because the administrative police and the judicial police are not divided in our police system. The administrative police should establish its line independently and manage genuine police activities to its belief on its own responsibility, otherwise it can consult with the prosecution for the area of the judicial police only. Third, we should specialize the present police investigation system. It is tough to deal with the recent change of the criminal pattern in the present police investigation system. First of all, it is necessary to cultivate special investigators who are proficient in a variety of criminal fields. We should anchor down the lifelong investigator system as soon as possible being tried inside the present police and it can help investigation capacity switch drastically. Now it is time to establish a new investigation paradigm which corresponds with the times and a national demand and think about which system is the best for the people. The police should try to do its best to reinforce the investigation ability with constant self-reform, fair investigation and investigation service of high quality to the nation.

복권기금 문화예술사업 활성화 방안 연구 : 문화복지의 관점에서

성기현 동국대학교 문화예술대학원 2007 국내석사

Entering the global age in the 21st century, competitive edge based on "culture" has increasingly replaced material competitivity as the deciding factor of a nation's competitive power. In Korea, it's been already almost ten years since the government employed cultural welfare as one of the major directions in its cultural policies. Unfortunately, however, there are still no systematic laws regarding cultural welfare. Thus this study set out to search for the ways to activate cultural welfare through the lottery fund. Currently Korea is in the early stage of cultural welfare, and so is the lottery fund. Since 2004 when the influx of the lottery fund started into the culture and art community, a focus has gradually shifted in support for the community from the projects that emphasize artistic originality and creativity to those that try to appease the materialistically and economically alienated class. The global village is changing from the "welfare state" to the "welfare society" and from "passive welfare" to "active welfare." The current policy directions of the Lottery Committee definitely seem to go in reverse to those changes. It's even likely that they can be regarded as an element of a nanny state and detrimental to the growth of Korea's cultural welfare in its infancy. Trying to address the problems with the lottery fund-aided projects, the investigator examined the structure of the Lottery Committee and the current state and issues of public projects based on the lottery fund. In case of the Promotional Fund for Culture and Art which receives grants from the lottery fund, it's hard to predict future projects due to the constant changes to its budget caused by the instability of the lottery fund itself and the approach of collecting fund publicly. The current movement to privatize the Promotional Fund for Culture and Art can jeopardize the influx of the lottery fund. They should find some ways to guarantee long-term influx of the lottery fund in order to prevent it from happening. It seems like a good idea to apply fixed distribution rates for a certain period of time in allocating the lottery fund because the current fluid distribution rates, which have been identified as one of the problems of lottery fund-aided projects, do hamper the growth of the projects. But the problem is that there are no solid grounds in respect to the specific distribution rates. Thus it's necessary to introduce a procedure of collecting public opinions to build grounds for such policies and induce an agreement from people, who are the actual resource of the lottery fund. It's also necessary to reform the perceptions of the staff in charge of the business of the lottery fund-aided projects. The Ministry of Culture and Tourism and the Arts Council Korea should define each others' roles clearly and thus reduce unnecessary frictions between them, making a contribution to heightening the quality level of culture and art projects aided by the lottery fund. The artists and concerned organizations also need to change their perceptions. It's an often case that they don't analyze the recipients of the lottery fund thoroughly in planning project contents, which has led to the multiplication of one-time projects aiming at benefiting from the lottery fund. Such projects can shorten the life of culture and art projects aided by the lottery fund. Also essential to the longevity of lottery fund-aided projects are the changes to people's perceptions. The majority of lottery buyers are from the middle- or lower-income class. There are some questions raised about the regressivity of income, arguing that it doesn't serve the principles of equality to collect money from those classes and use it for public projects. It's also been criticized that it's not right to collect money appealing to the speculative spirit of people and to grant it to public projects. Those questions and criticisms can be resolved if people change their perceptions of lottery fund-aided projects and understand they are for the realization of cultural welfare. There will be no ongoing growth of cultural welfare without the expansion of its meaning. The cultural welfare policies by the Korean government including the lottery fund focus on "passive cultural welfare." The benefits of cultural welfare should expand from the current economic domain to include the entire population in order to meet their intellectual needs as well as their economic and material ones. Once necessary funds are secured to activate cultural welfare, they should take on educating professionals in cultural welfare to maintain the consistency of cultural welfare. The education of cultural welfare workers and culture coordinators recently suggested by the culture and art community will work to solidify the infrastructure of Korea's cultural welfare. The 21st century is the century of culture. A nation's cultural growth can create chances to promote its excellence home and abroad. The study results reveal some information about the current state of Korea's cultural welfare and the situation and problems of the lottery fund, whose influx to the culture and art community started in recent years. But it was not easy to maintain research consistency throughout the study because of the blurry boundaries of cultural welfare, which highlights even more the absence of laws and policies regarding culture welfare. The investigator felt sorry not to provide more in-depth discussions about the impacts of lottery fund-aided projects on the culture community. It's expected that the results will contribute to the growth of culture and art projects aided by the lottery fund as well as the activation of cultural welfare.
