In this paper, it is to identify the effects of differences in interpretation levels depending on the type of brand association and the brain psychological distance on the evaluation of the product of that brand through two experiments. To test our hypotheses empirically, we conducted online survey. We addressed the hypotheses involving the general and relative impact of actual and ideal self-congruence on emotional brand attachment (H1) and explored the effect of product involvement as the moderating variable (H1-1 and H1-2). The goal of this research was to validate the results from involving our basic model and to explore the impact of two additional moderating variables (self-esteem and public self-consciousness: H2). We followed the same procedure. This finding is theoretical to the extent of the interpretation level theory in brand association research by applying the interpretation level theory to the brand association, and provides the meaning that, in practice, it is necessary to utilize the message of different types of brain psychological distance depending on the brand association characteristics that the brand has in defining the brand. In particular, it was confirmed that functional brand associations and symbolic brand annals have representational harmonization, respectively, depending on the low and high levels of interpretation levels.

In this study, using the job history data of the Youth Panel(1-12th year: 2007 ~ 2018) of the Korea Employment Information Service, it is found that characteristics and duration distribution of first jobs of wage and salary worker, and estimated the factors of first job exit by utilizing survival analysis. As a result of the analysis, regular workers are less likely to leave their first jobs than temporary/daily workers. In addition, the group with a high degree of major congruence was found to have a lower chance of leaving the first job than the group with a major mismatch. And the higher the income level, the lower the probability of departure, which shows that the possibility of leaving low-income workers is very high.

ADHD 아동의 주의장애 원인이 반응 결정에서의 억제의 미숙인지, 전반적인 주의 기능의 미숙인지 알아보기 정상아동과 ADHD 아동을 대상으로 flanker 과제를 실시하였다. 실험 1 에서는 방해자극과 목표자극의 일치 (3: 일치, 불일치, 중립), 방해자극과 목표자극의 SO (3: -100, 0, 100 ms), 집단 (2; 정상, ADHD)의 3 요인 실험을 실시하였다. 정상아와 ADHD 아동간에 반응시간에서는 차이가 없었다. 그러나 정상아동에 비해 ADHD 아동이 부정확 반응을 더 많이 하였다. 특히 방해자극이 100 ms 먼저 제시되기 시작하는 SOA -100 ms 조건에서 두 집단의 차이가 크게 나타났다. 이 결과가 반응결정 단계에서의 억제에서 비롯되는 것인지 알아보기 위해 실험 2 에서는 목표자극의 반응 set(좌, 우)에 포함되지 않는 방해자극(상, 하로향함)을 제시하는 무관련조건을 추가하여 실험을 실시하였다. 실험 1 과 같이 불일치조건에서는 정상아동에 비해 ADHD 아동이 오반응을 더 많이 산출하였다. 그러나 무관련조건에서는 정상아와 ADHD 아동 간에 오반응에서 차이가 없었다. 즉 두 집단 모두에서 중립조건보다 무관련 조건에서 반응시간은 길었으나, 오반응에서는 차이가 없었다. 즉 정상아와 ADHD 아동 모두 전반적인 주의에서는 차이가 없다는 것을 시사하였다. 두 실험의 결과는 정상아에 비해 ADHD 아동이 반응 결정 단계에서의 억제에서 차이가 나는 것을 시사하는 것으로 해석되었다.

Even though, anterior knee pains are most frequently encountered in knee clinics, many physicians use a 'recipe'-type of approach to their treatment. But many predisposing factors have been included internal rotation of the femur, valgus knee alignment, external rotation of the extensor mechanism, patellar alta, a flat trochlear groove, patella with poor congruence and ligatmentous laxity. Many scientific principles on which these commonly used treatment are based, can lead to refinements and improvement in treatment. We reviewed and summarized the recent functional anatomical and biomechanical data that are most relevant to the contemporary treatment of patellofemoral joint disorders.

The purposes of this study are to survey stereotypes of control-display relationships for seven principal controls in passenger cars using the paper-pencil and hardware tests, and to examine stereotype strength of the paper-pencil test through comparing the stereotypes for the controls derived by the two methods. Ninety two and 60 college-aged students participated in the paper-pencil test and the real car simulation of the hardware test, respectively. There are dominant motion-directions for all controls in the paper-pencil test, while in the hardware test, there are dominant motion-directions for six controls including head light, high beam, door window, ignition key, door key and door lock controls. The stereotypes of motion-directions for six controls obtained by the paper-pencil test were the same as or similar to those by the hardware test. It was inferred from this that the congruence of the stereotypes by the two methods might be attributed to two simple motion-direction principles of 'clockwise for increase' and 'upward for increase.' Although it is known that the hardware test would be best for obtaining accurate stereotypes between controls and displays, this study implies that if the paper-pencil test is well designed, the paper-pencil test can produce the same results as the hardware test at low cost and without consuming time.

In this paper, a robust $H\infty$ stabilization problem to a uncertain discrete-time nonlinear systems with time-delay via fuzzy static output feedback is investigated. The Takagj-Sugeno (T-S) fuzzy model is employed to represent an uncertain nonlinear system with time-delayed state. Then, the parallel distributed compensation technique is used for designing of the robust fuzzy controller. Using a single Lyapunov function, the globally asymptotic stability and disturbance attenuation of the closed-loop fuzzy control system are discussed. Sufficient conditions for the existence of robust $H\infty$ controllers are given in terms of linear matrix inequalities via similarity transform and congruence transform technique. We have shown the effectiveness and feasibility of the proposed method through the simulation.

This study analyses "Survey of Health and Behavior of Children and Adolescents" which is conducted by National Youth Policy Institute that investigated influential factors in difference between actual obesity and perceptional obesity. GLM (Generalized Linear Mode) was carried out to estimate the effects on the eating habits and physical activities and multinomial logit analysis was carried out to examine the influential factors in difference between actual, obesity and perceptional obesity. The results of this study are shown as follows. First 72.0% of total respondents showed the congruence between actual obesity and perceptional obesity and 24.6% of total respondents perceived them fatter than actual. The remaining 3.5% perceived them thinner than actual. Second, the main effects of actual obesity and perceptional obesity on eating habits were statistically significant, but interaction effect between them was not statistically significant. The main effects of actual obesity and perceptional obesity on physical activities and interaction effect between them were all statistically significant. Third, the influential factors in difference between actual obesity and perceptional obesity were gender, age, school record, education of parents, subjective economic status, and living together with family.

The primary purpose of this study was to investigate the nature and relationship of attitudes of mothers and their daughters concerning the value of children. the secondary interest was to compare this study with the American studies done by Bormann & Stockdale(1979), and Leavy & Hough(1983). Subjects for the study were college-age daughters their married sisters, and their mothers. The“Fawcett Opinions about Children Questionnair”was used to measure beliefs about children. Pearson Product Moment Correlations were computed for mother-daughter(married), mother-daughter(unmarried), and daughter(married)-daughter (unmarried) on each of nine subscales on value of children. To study the generation differences and marriage differences, matched sample t-test were carried. Several significant relationships were found for mother-daughter (married), daughter(married)-daughter (unmarried) pairs. Only one significant relationship was found for mother-daughter(unmarried) pairs. Significant differences were found between mother's group and daughters' groups on most subscales except one or two (generation effect). Significant differences were found between married daughters and unmarried daughters on 4 subscales(marriage effect). The results did not corroborate the findings of American studies which revealed the lack of congruence between mother and daughter attitudes. It was noted that as daughters had children themselves, their attitudes toward children had become more congruent with their mothers. There was also evidence to support the generation differences between mothers and daughters values. It was concluded that both value similarity and generation differences vary as a function of the particular events as well as age-itself.

Let $m$ and $k$ be any positive integers, let $\mathbb{Z}_k$ the ring of integers of modulo $k$, let $G_m(\mathbb{Z}_k)$ the group of all $m$ by $m$ nonsingular matrices over $\mathbb{Z}_k$ and let ${\phi}_m(k)$ the order of $G_m(\mathbb{Z}_k)$. In this paper, ${\phi}_m(k)$ can be computed by the following investigation: First, for any relatively prime positive integers $s$ and $t$, $G_m(\mathbb{Z}_{st})$ is isomorphic to $G_m(\mathbb{Z}_s){\times}G_m(\mathbb{Z}_t)$. Secondly, for any positive integer $n$ and any prime $p$, ${\phi}_m(p^n)=p^{m^2}{\cdot}{\phi}_m(p^{n-1})=p{^{2m}}^2{\cdot}{\phi}_m(p^{n-2})={\cdots}=p^{{(n-1)m}^2}{\cdot}{\phi}_m(p)$, and so ${\phi}_m(k)={\phi}_m(p_1^n1){\cdot}{\phi}_m(p_2^{n2}){\cdots}{\phi}_m(p_s^{ns})$ for the prime factorization of $k$, $k=p_1^{n1}{\cdot}p_2^{n2}{\cdots}p_s^{ns}$.

Although aspiration towards quality of life and holistic health has been growing faster in our modern society and the affordance of health in built environment has been more acknowledged, there has been hardly any development on built environment planning and design theory that can be comfortably and confidently used in creating built environment to promote holistic health. Thereby, this study sets out to experimently formulate a composite theory that explains the relationship between health and built environment. The main methodology of this study is literature review and analysis. Theories that have been applied in other similar fields were chosen to be analyzed by health related perspectives and graft those theories onto holistic health viewpoints to compose a comprehensive theory. Selected theories that were considered useful to be analyzed were Lawton's Environment Press Theory, Carp & Carp's Complementary & Congruence Theory, Valins' Activity-based Design Criteria Theory, Atchley's Continuity Theory, Murtha & Lee's User Benefit Criteria Theory, and Alexander's Pattern Language Theory. Characteristics of these theories were compared by their abstractness and concreteness, and the range of application, and analyzed by a holistic health perspective. Then, these theories were comprehensively structuralized and synthesized as a built environment for health theory. This study has its significance in providing a base to develop healthy built environment research further as it introduced a conceptual framework which explains spatial elements in the health functionality point of view.
