본 연구는 기내안전정보에 관한 승객 인지에 대해 행동이론을 적용하였으며, 이를 통하여 안전행동 의도에 미치는 영향을 분석하고자 하였다. 또한, 대표적인 소비자 행동이론인 계획된 행동이론과 트라이앤디스 행동이론의 비교를 통해 기내안전정보 인지에 따른 안전행동 의도를 설명하기 위한 모형의 특징파악을 목적으로 하고 있다. 연구목적을 달성하기 위해 선행연구를 토대로 연구모형과 가설을 수립하였으며, 370명의 항공여행을 경험한 승객을 대상으로 설문을 통해 경로분석을 실시하였다. 분석 결과, 계획된 행동이론은 태도와 지각된 통제가 안전행동 의도에 긍정적 영향을 미치는 것으로 나타났으며, 트라이앤디스 이론은 사회적 영향과 습관이 안전행동 의도에 긍정적인 영향을 미치는 것으로 나타났다. 또한, 두 모형의 비교를 통해 기내안전정보 인식과 안전행동 의도의 관계에서 인식과 감정의 심리적 과정이 모두 동반된다는 점을 확인하였다.

In this note, we study a comparison principle for elliptic obstacle problems of p-Laplacian type with L¹-data. As a consequence, we improve some known regularity results for obstacle problems with zero Dirichlet boundary conditions.

A free vibration analysis is made of a moderately-thick toroidal shell based on a shear deformation (Timoshenko-Mindlin) shell theory. This work represents an extension of earlier work by the authors which was based on a thin (Kirchoff-Love) shell theory. The analysis uses a modal approach in the circumferential direction, and numerical results are found using the differential quadrature method (DQM). The analysis is first developed for a shell of revolution of arbitrary meridian, and then specialized to a complete circular toroidal shell. A second analysis, based on the three-dimensional theory of elasticity, is presented to cover thick shells. The shear deformation theory is validated by comparing calculated results with previously published results for fifteen cases, found using thin shell theory, moderately-thick shell theory, and the theory of elasticity. Consistent agreement is observed in the comparison of different results. New frequency results are then given for moderately-thick and thick toroidal shells, considered to be completely free. The results indicate the usefulness of the shear deformation theory in determining natural frequencies for toroidal shells.

Based on a weakly non-Gaussian theory the occurrence probability of freak waves is formulated in terms of the number of waves in a time series and the surface elevation kurtosis. Finite kurtosis gives rise to a significant enhancement of freak wave generation in comparison with the linear narrow banded wave theory. For fixed number of waves, the estimated amplification ratio of freak wave occurrence due to the deviation from the Gaussian theory is 50% - 300%. The results of the theory are compared with laboratory and field data.

Harmonics and fundamental reactive power of nonlinear loads in serious unbalanced power condition are compensated by current synchronous detection(CSD) theory which is also acceptable for single phase power system, but the CSD theory is not suitable any more in case of controlled independently harmonics and reactive component. Therefore a new algorithm the extended current synchronous detection (ECSD)theory for a three phase active power filter based on decomposition of fundamental reactive distorted components is proposed in this paper. The proposed ECSD theory is simulated and tested comparison with a few power theories under asymmtrical condition in power system.

This study investigates factors that impact dating relationship stability(DRS) among college students by applying two key concepts from the Interdependence Theory suggested by Kelly & Thibaut (1978; Thibaut & Kelly, 1959), the comparison level(CL) and comparison level for alternatives($CL_{alt}$). This study also examined mediating effects of commitment on the relationship between CL and DRS and $CL_{alt}$ and DRS. The research used a survey data set drawn from 327 college students currently involved in a dating relationship. The collected data set was then analyzed using SPSS software ver. 23.0 and AMOS software ver. 25.0, to produce the descriptive statistics, Pearson's correlations, and path analysis with bootstrapping. First, both CL and $CL_{alt}$ had a significant direct impact on DRS. In terms of effect size, CL's effect size was comparatively larger than $CL{_{alt}}'s$. The mediating effects from the commitment were evidenced. In the model, the commitment partially mediated the relationships between CL and DRS, and $CL_{alt}$ and DRS. The findings suggest that commitment still plays a key role in dating relationships among college students who currently have a romantic partner. The findings of this study show the possibilities in applying the concepts and theory of interdependence to explain current dating relationships among young adults.

Objective : Through the comparison of the Eumyang(陰陽) theory between Hwangjenaegyeong(黃帝內經) and Juyeok(周易) Gyesajeon(繫辭傳) written by Gongja(孔子), the philosophical background of Hwangjenaegyeong(黃帝內經) and the position of Eumyang theory in the ancient academic society can be clearly understood. Method : The similarities and differences of the Eumyang theory in Hwangjenaegyeong(黃帝內經) and Juyeok(周易) Gyesajeon(繫辭傳) are categorized and analyzed comparing both texts. Results & Conclusion : Hwangjenaegyeong(黃帝內經) and Juyeok(周易) all recognized Eumyang movement as the most important and basic principle of the change of the universe. In the relationship between Eum(陰) and Yang(陽), the key of harmonization of them is to keep and practice the virtue of each others. The plentiful expression of Juyeok(周易) Gyesajeon(繫辭傳) about the relationship of Eumyang is helpful to understand and apply the concepts of Eumyang to daily life. The other hand, Hwangjenaegyeong(黃帝內經) as medical text, concentrates upon the explanation about the movement and circulation of Gi(氣) between Eum and Yang.

단순한 쿨롱액체들의 채심입방정계의 구조와 열역학적 성질들은 일성분 플라즈마에 대한 섭동론으로부터 계산된다. 섭동론(PT)과 Monte Cario(MC) 데이타의 비교는 좋은 일치를 보인다. 강체구 섭동론은 일성분 플라즈마 같은 먼 거리의 인력계에 적절하다. PT와 MC 데이타에 대한 동경 분포함수(g(r))와 구조인자(S(q))의 비교에서 일치를 보인다. 따라서 섭동론은 쿨롱액체의 성질 및 구조를 설명하는데 유용한 방법이다.

Purpose - In this study, I attempt to clarify three theories of firm boundaries (vertical integration): the principal-agent theory, transaction cost theory, and property rights theory. Although these theories have been widely cited and much discussed, it has been found that understanding the commonalities and distinctions of these seemingly familiar theories is difficult. Design/methodology/approach - I present the three theories about the decisions that firms make concerning their boundaries. Then, I compare elemental versions of the theories of the firm. Findings - Comparing the ingredients of the elemental property rights and principal-agent theories shows that they provide a unified account of the costs and benefits of vertical integration. However, the property rights theory in no sense formalizes the transaction cost theory. Research implications or Originality - Clarifying the three theories of the firm can help to construct empirical models and interpret its results.

Purpose The purpose of this study is to analyze the current state of grounded theory methodology in Korea information systems studies and to suggest its application strategies. Design/methodology/approach After reviewing previous studies, this study reviewed 16 papers which adopted grounded theory methodology and analyzed these papers by two ways, research contents and methods adopted from grounded theory methodology: Main characteristics in grounded theory methodology are selected as main criteria in analysis such as data collection method, constant comparison, software use, coding ways, suggested model, proposition suggestion etc., while subject, theory/practice orientation, and role of prior knowledge are included in research contents. Findings Based on the review and analysis, this paper suggested four guidelines for adopting grounded theory methodology to information systems research in Korea: First, division of research methodology into stages. Second, explicit documentation of research process. Third, pursuit of diversity in research topics. Fourth, strengthening scale up and theoretical integration.
