This study aimed to provide a desirable way to design culinary education programs at university by investigating the relationship between student satisfaction with education and job preference based on their high schools. The results of this study showed that a high percentage of students decided to choose culinary arts as their major by themselves. Most students found a career in the culinary field demanding, nevertheless, they appeared to have a strong desire to take up the challenge. Students from culinary high schools showed low satisfaction with their practical cooking courses, while students from vocational high schools seemed to be highly satisfied with those same courses. On the other hand, students from academic high schools showed a high satisfaction with their theory courses, which factored into their decision to choose culinary arts as their major. However, there appeared to be no significant difference in job preference according to the students. Most students, regardless of satisfaction with their education, considered working abroad. On the basis of these results, it is suggested that a culinary training program in universities should be divided tin three groups; academic, vocational & culinary. Each group to have classes in theory, practical and English designed with respect to their prior high school training. In addition, an opportunity for overseas employment should be offered to all three categories.

Based on the premise that a systematic career process was one of the essential elements of successful task performance both for individuals and the organization in the field of social welfare, this study set out to empirically analyze factors influencing the career commitment of social workers at a multidimensional level and provide practical implications for the directionality of career management on the basis of data with theoretical and statistical accuracy. For those purposes, the study collected individual and organizational characteristics data from 787 social workers at 46 agencies through a structured questionnaire and analyzed influential factors through the multilevel analysis technique by taking organizational effects into account. The analysis results show that explanations by the organization characteristics recorded significant 15% in the total variance of career commitment and that its influential factors included such significant variables as the protean career attitude, desire for growth, human network, and self-efficacy at the individual level and also the qualification compensation system at the organizational level. The study then proposed and discussed integrated practice strategies between individuals and agencies as the measures to promote career success through the activation of individual factors based on the consideration of organizational effects such as the application of an employee assistant program, provision of incentives to professional career development, and shift to a learning organization.

본 연구에서는 전 세계적으로 활발히 연구되고 있는 나노바이오센서 분야 중 가장 주목을 받고 있는 LSPR 원리를 이용한 바이오센서를 제작하였다. 금속 나노입자의 국소 표면 플라즈몬 공명현상에 의한 주위환경에 민감하게 반응하는 특성은 고감도 광학형 바이오센서, 화학물질 검출 센서등에 응용된다. 특히 금 나노막대와 같은 1차 나노구조물은 나노막대의 주변 환경 변화에 따라 뚜렷한 플라즈몬 흡수 밴드 변화를 나타냄으로 센서로 적용 했을 때 고감도의 측정이 가능하다. 본 연구에서는 다공성인 알루미늄 양극산화 박막 주형틀을 이용하여 다양한 종횡비를 가지는 금 나노막대를 합성하고, 나노막대 어레이 형태의 박막을 제작하였다. 금 나노막대의 합성은 알루미늄 양극산화막을 사용한 주형제조 방법(template method)을 사용하는 전기화학 증착법을 사용하였다. 우선 부도체인 알루미늄 양극 산화막의 한쪽면을 열증착 장비를 사용하여 금을 증착하여 작업 전극(working electrode)을 형성하였다. 백금 선(platinum wire)을 보조 전극(counter electrode)으로 사용하고 Ag/AgCl 전극을 기준 전극(reference electrode)으로 사용하여 삼전극계(three-electrode system)를 형성하였으며, 금 도금 용액(orotemp 24 gold plating solution, TECHNIC INC.)을 사용하여, 800 mV 전압에서 금 나노 막대를 합성하였다. 금 나노막대의 길이는 테플론 챔버를 통과한 전하량 또는 전기 증착 시간에 비례하여 결정된다. 금 나노막대를 성장시킨 알루미늄 양극산화막을 실리콘 웨이퍼에 은 페이스트를 사용하여 고정시킨 후 수산화나트륨 (NaOH)용액을 사용하여 알루미늄 양극산화막을 녹여내어 수직방향으로 정렬되어 있는 나노 막대 어레이 박막을 제조 하였다. 또한 제작된 금 나노막대 어레이의 광학적 특성을 평가하였다. 본 연구에서와 같이 나노막대를 직경방향으로 측정할 경우, 직경방향의 transverse mode만 측정된다. 금 나노 막대가 알루미늄 양극산화막 안에 포함된 상태로 측정된 금 나노로드 어레이 박막의 광 스펙트럼 분포는 금 나노막대의 가시광영역에서의 흡수 스펙트럼을 측정하였을시 직경 및 길이에 따라 transverse mode의 ${\lambda}$ max (최대 흡광)의 위치가 변화됨을 나타낸다. 실험 결과를 바탕으로 나노막대의 종횡비가 증가함에 따라 흡수 스펙트럼의 transverse mode ${\lambda}$ max가 미약하게 단파장 영역으로 이동하는 것을 확인할 수 있다. 이러한 결과는 원기둥 형태의 금 나노막대의 흡수 스펙트럼에 대한 이론적인 예측과 부합한다. 바이오센서로의 적용 가능성을 확인하기 위하여 자기조립단분자막을 형성하여 항체를 고정하고 CRP에 대한 응답특성을 평가하였다. CRP 항원-항체의 면역반응에 대한 실험 결과 CRP 항원의 농도가 증가함에 따라 넓은 측정범위에서 선형적으로 흡광도가 증가하는 결과를 나타내었으며, CRP 10 fg/ml의 농도까지 검출할 수 있었다. 센서의 선택성을 확인하기 위하여 감지하고자하는 대상물질이 아닌 Tn T 항원을 감지막에 반응시켜 흡광도 변화를 분석하였다. 결과적으로 제작된 센서칩은 선택성을 가지고 측정하고자하는 물질에만 반응함을 확인하였다. 이러한 결과는 다양한 직경을 사용한 부가적인 LSPR현상의 연구에 활용될 수 있을 것이다.

Epistemological development process of the Fundamental Theorem of Calculus is considered in a history of mathematical notions and the genetic process of the Fundamental Theorem is arranged by the order of geometric, algebraic and formalization steps. Based on this, we studied students' episte- mological obstacles and error and analyzed the content of textbooks related the Fundamental Theorem of Calculus. Then, We developed the "Folding Back Model" of the fundamental theorem of calculus for students to lead meaningful faithfully. The Folding Back Model consists of "the Framework of thou- ght"(figure V-1) and "the Model of genetic understanding of concept"(figure V-2). The framework of thought in the Folding Back Model is included steps of pedagogical intervention which is used "the Monitoring working questions"(table V-3) by the mathematics teacher. The Folding Back Model is applied the Pirie-Kieren Theory(1991), history of mathematical notions and students' epistemological obstacles to practical use of instructional design. The Folding Back Model will contribute the professional development of mathematics teachers and improvement of thinking skills of students when they learn the Fundamental Theorem of Calculus.

Today, nuclear energy conflict is caused from the dangerous radioactive material. The main party of this conflict are politic and economic systems which deride nuclear energy, and the persons concerned which it oppose and the anti-nuclear environment group. If the nuclear waste is transported from one nation to another nation, multi national anti-nuclear group appears as conflict party. We call this domestic and transnational risk communication new social movement. From the viewpoint of system theory, the new social movement can mean the offensive development of self-reference which withstand the "technicalization of communication" through the "symbolically generalized communication media" like money and power. By comparing Northeast Asia and Europe, the nuclear energy conflict did not show a big difference in the selection of nuclear waste storing site. In the Northeast Asia, when Taiwan exports the nuclear waste to North Korea, the international conflict broke out. In Europe, Germany has a hard experience with the construction-plan for the re-treating plant that produces the plutonium from the dangerous nuclear waste, and with the transnational transport of the nuclear waste. The new social movement aims the global paradigm which is able to guarantee the subtainability of ecological environment. The nuclear conflict in the "world risk society" is solved through the "discourse-alliance" which accomplishes sub-politics by crossing the border of class, nation and system.

This study aims to study the impact of pet attachment on subjective well-being, focusing on individuals who live with pets. In addition, it is to recognize that their basic psychological requirement mediates between pet attachment and subjective well-being. For this purpose, a survey was performed on 358 adults living with pets nationwide. The final data of 319 people were evaluated after excluding invalid information. Dependent on the theoretical approach of the attachment theory, the human-pet relationship was examined by dividing it into two orthogonal dimensions pet attachment prevention and pet attachment anxiety(Zilcha-Mano et al., 2011). The mediating effects were investigated as an in-depth mechanism that mediates between pet attachment and subjective well-being, the mediating effects were examined, in terms of the three basic psychological needs of Self-Determination Theory, which are autonomy, competence, and relatedness. As an outcome, first, pet attachment prevention and pet attachment anxiety both revealed a negative correlation with subjective well-being. Second, basic psychological needs, which are autonomy, competence, and relatedness, are mediated between pet attachment and subjective well-being. Autonomy, competence, and relatedness fully mediated the relationship between pet attachment avoidance and subjective well-being. Meanwhile, in the case of pet attachment anxiety, only autonomy among basic psychological needs is fully mediated between pet attachment anxiety and subjective well-being in the case of pet attachment avoidance. This means that pet attachment prevention or pet attachment anxiety correlates with subjective well-being by satisfying basic psychological needs instead of directly affecting personal well-being. Regarding the pet effect, it is meaningful to find an in-depth mechanism that the human-pet relationship has for an adaptive and positive impact on humans.

This paper deals in depth with airline over-booking practices and legal questions therefrom in the light of public interests. Chapter I as an introduction gives clear ideas of what are the over-booking, fact-revealing current state of denied boarding and nature of the problems inherent but veiled in those practices. In Chapter II, it is reviewed whether legal instruments for DBC(Denied Boarding Compensation) are adequately equipped for airline passengers in R. O. K. Upon the results of the review that international law to which Korea is a party, domestic law and administrative preparedness for the DBC are either null or virtually ineffective, the Chapter by contrast illustrates how well the U. S. and the E. U. safeguard civil rights of their passengers from such an 'institutionalized fraud' as the over-booking. In Chapter III on which a main emphasis lies, it is examined whether the over-booking practice constitutes a criminal offense: Fraud. In section 1, the author identifies actus reus and mens rea required for fraud then compares those with every aspect of the over-booking. In conjunction with the structural element analysis, he reviews the Supreme Court's precedents that lead the section into a partial conclusion that the act of over-booking judicially constitutes a crime of fraud. Despite the fulfillment of drawing up an intended answer, the author furthers the topic in section 2 by arguing a dominant view from Korean academia taking opposite stance to the Supreme Court. The commentators assert, "To consummate a crime of fraud, there must be property damage of the victim." For this notion correlates with a debate on legally protected interest in criminalization of fraud, the section 2 shows an argument over 'Rechtgut' matters specific to fraud. The view claims that the Rechtgut comes down rather to 'right to property' than 'transactional integrity' or 'fair and equitable principles'. However, the section concludes that the later values shall be deemed as 'freedom in economic decision-making' which are the benefit and protection of the penal law about fraud. Section 3 demonstrates the self-contradiction of the view as it is proved by a conceptual analysis that the infringement on freedom in economic decision-making boils down to the 'property damage'. Such a notion is better grounded in section 4 by foreign court decisions and legislation in its favour. Therefore, this paper concludes that the airline's act of over-booking is very likely to constitute fraud in both theory and practice.

Untact mobile commerce shows a rapid growth due to the prolonged COVID-19 pandemic. And companies have a lot of tough competition in this trend. However, the detail pages of products which play an important role in purchase decision have been provided mostly for consumers in a form of stereotyped information composition. This study has found that the form of (image-centered vs. text-centered) information composition of detailed descriptions of products in the detail pages of mobile products has an effect on product attitude and purchase intention as consumers' information appeal methods vary depending on product types (search goods vs. experience goods). That is, search goods whose information search is easy and whose quality is predictable could be found that product attitude and purchase intention have a more positive effect on the form of image-centered information composition. And experience goods whose quality is unpredictable could be found that product attitude and purchase intention have a more positive effect on the form of text-centered information composition. And effects of congruence between product types based on Higgins' regulatory focus theory and the form of information composition have found to vary depending on consumers' chronic regulatory focus. Promotion focus seeking consumers showed effects of congruence between product types and the form of information composition and prevention focus seeking consumers did not show effects of congruence between them. That is, promotion focus seeking consumers have found to have more positive product attitude and purchase intention in the form of image-centered information composition of experience goods and text-centered information composition of search goods. And prevention focus seeking consumers have found to be unable to have an effect on product attitude and purchase intention even though the form of image or text-centered information composition of search and experience goods is presented. The study implies that the form of information composition should be designed, produced, and provided for consumers by considering product types and consumer propensity when designing it in the detail pages of mobile products.

The purpose of this study is to investigate the mediating effects of psychological empowerment between participative leadership and creative behavior. Especially, it aims to analyze the unidimension and multidimension of psychological empowerment in an integrated manner, and to suggest effective practice of participative leadership together with theoretical and methodological implications. In this study, the dependent variable was measured separately with time lag as a method to solve the common method bias that can be shown by the self-report type survey method, and positive emotions and negative emotions expressing emotional states in job situations were employed as control variables along with rank. A total of 283 questionnaires were collected from employees who work for companies in various industries with more than 300 domestic employees. SPSS PROCESS macro program('model 4') was used for statistical analysis. Results, First, the full mediation effect of psychological empowerment(unidimension) was confirmed in the relationship between participative leadership and creative behavior. Second, the analysis of the multidimension of psychological empowerment revealed the full mediating effect of meaning, self-determination, and impact, and the mediating effect of competence was not significant. Third, as a result of comparing the mediating effects of unidimension of psychological empowerment and the mediating effects of multidimension, the magnitude of mediating effect of unidimension was found to be much greater than mediating effect of multidimension. And The magnitudes of the three multidimensional mediating effects were similar. This is a case in which the motivational model of participative leadership revealed in the overseas study is proven in the domestic management environment and is significant in that it is the basis of future research. Based on the results of the empirical studies, the implications and limitations of the study and future research directions are presented.

The purpose of this study is to compare happiness between Korean elderly residing in South Korea and those residing in New York City area in United States (Korean American elderly), and to investigate important factors determining their happiness. We collected data from 1,988 elderly residing in Chuncheon and Seoul in South Korea and 173 elderly residing in New York City area. All samples were over 65 years old in 2005. In general, Korean American elderly seemed happier than Korean elderly. Our specific data analysis showed that Korean American elderly had higher scores in non-agitation, satisfaction for aging, and satisfaction for life than Korean elderly. And they showed secure attachment more and insecure attachment less than Korean elderly. Social support network, satisfaction in psychological need, health, daily routines, and social background predicted happiness significantly for both Korean American elderly and Korean elderly. For American Korean elderly, satisfaction in psychological need predicted satisfaction for aging, satisfaction for life, and secure attachment significantly when social background, health, and daily routine were controlled. For Korean elderly, satisfaction in psychological need predicted all sub-factors of happiness significantly, and social support network also predicted happiness significantly when social background, health, and daily routine were controlled. Additional data analysis compared social support network, satisfaction in psychological need, health, daily routine, and social background between Korean American elderly and Korean elderly. Korean American elderly seemed to have more solid social support network and to have higher satisfaction in psychological needs than Korean elderly. Korean American elderly perceived themselves as healthier, and their life style related health was much healthier than Korean elderly. In social background, Korean American elderly had higher education and economic level than Korean elderly. Roles of social support network and satisfaction in psychological need for happy aging were discussed in terms of previous theoretical explanation of successful aging.
