In this paper, we present a two-stage vision-based approach to detect multi views of pedestrian in road scene images. The first stage is HG (Hypothesis Generation), in which potential pedestrian are hypothesized. During the hypothesis generation step, we use a vertical, horizontal edge map, and different colors between road background and pedestrian's clothes to determine the leg position of pedestrian, then a novel symmetry peaks processing is performed to define how many pedestrians is covered in one potential candidate region. Finally, the real candidate region where pedestrian exists will be constructed. The second stage is HV (Hypothesis Verification). In this stage, all hypotheses are verified by Support Vector Machine for classification, which is robust for multi views of pedestrian detection and recognition problems.

This study examined the mediating effect of management's values on organizational performance and between them. Hypotheses 1, 2, 3, and 4 which were set up to achieve the purpose of this study, were verified as follows. First, Hypothesis 1 proposed that the values of management will have a positive effect on organizational performance. Second, Hypothesis 2 proposed that the values of management are likely to have a positive effect on the consistency of the values of organizational members. Third, Hypothesis 3 proposed that the consistency of the values of organizational members will have a positive (+) influence on organizational performance. We found that the consistency of the values of organizational members has a positive (+) influence on organizational performance. Hypothesis 3 was adopted. Fourth, hypothesis 4, the value consistency of the members of the organization, had a mediating effect between the organization performance on value management. The results of this study were all adopted research hypotheses. Therefore, management's values have a significant impact on the theoretical and practical aspects by showing the relationship between organizational members' value consistency and organizational performance. In the future, the necessity of further research on management's values and member's value consistency through various fields for organizational performance has emerged.

We explicate the forming mechanism of Sasang constitution as the principle of energy distribution which is based on the evolutionary hypothesis. The result was obtained as follows: 1. The principle of form-image (形象) in oriental medicine can be explained with the relation between structure and function that a life acquires through the adaptation and evolution. 2. The Sung-jung (性情) in Sasang constitutional medicine can be explained as the strategy for survival or the pattern of adaptation by which an individual or a species lives in this world. 3. The forming mechanism of Sasang constitutional organic phase (臟局) can be explained as the principle of energy distribution which includes three hypothesis (hypothesis of limited resources, hypothesis of preference and hypothesis of effectiveness). 4. It is postulated that the local hemodynamics is one of the most important factors that determine the difference of Sasang constitutional organic function. 5. The relation of metabolic rate, local hemodynamics and thermo-metabolism is inseparable and it is the important point of forming mechanism of Sasang constitution and the diagnosis of pulse.

The hypothesis of ridge subduction which explains the Cretaceous igneous activities in East Asia including China, Korea and Japan, has been widely accepted in the society. Especially, the hypothesis explains the southwest-to-northeast migration of the Cretaceous adakite emergence in Southwest Japan. However, the hypothesis has several issues because the geochemical analyses and plate reconstruction model are not consistent with the consequences of the ridge subduction. To resolve the issues, a new hypothesis of the plume-continent and plume-slab interaction is suggested, which explains the igneous activities during the Cretaceous. In this review, I briefly introduce the two hypotheses and suggest an additional future study to prove the new hypothesis.

We study confirmed the factors influencing the organizational culture(collective culture, development culture, rational culture, hierarchical culture) perceived by members of the organization and the manager's authentic leadership(self-awareness, balanced information processing, relational transparency, internalized moral perspective) on job crafting. In addition, the relationship between organizational culture and authentic leadership was empirically analyzed. In order to verify the hypothesis of the research model, the survey results of 269 parts were verified as follows using the statistical program of SPSS 24.0. First, the organizational cultures perceived by members of the organization, development culture and rational culture, showed positive (+) influence on job crafting. In other words, Hypothesis 1 established by the research model was partially adopted. Second, the group culture, development culture, and rational culture of organizational culture were statistically significant in the relationship between the hypothesis 2 organizational culture and authentic leadership. In other words, Hypothesis 2 was partially adopted. Third, the three hypotheses of authentic leadership (self-awareness, balanced information processing, relational transparency, and an internalized moral perspective) all showed positive (+) effects on job crafting. As a result of this study, it was possible to confirm the importance of the organizational culture that improves the job-crafting of the members of the organization and the strategic activation plan for authentic leadership. Therefore, the necessity of strategic human resource development for the development and application of programs to revitalize organizational culture and improve the manager's authentic leadership has emerged.

Let L(s, χ) be the Dirichlet L-series associated with an f-periodic complex function χ. Let P(X) ∈ ℂ[X]. We give an expression for ∑^f_n=1 χ(n)P(n) as a linear combination of the L(-n, χ)'s for 0 ≤ n < deg P(X). We deduce some consequences pertaining to the Chowla hypothesis implying that L(s, χ) > 0 for s > 0 for real Dirichlet characters χ. To date no extended numerical computation on this hypothesis is available. In fact by a result of R. C. Baker and H. L. Montgomery we know that it does not hold for almost all fundamental discriminants. Our present numerical computation shows that surprisingly it holds true for at least 65% of the real, even and primitive Dirichlet characters of conductors less than 10⁶. We also show that a generalized Chowla hypothesis holds true for at least 72% of the real, even and primitive Dirichlet characters of conductors less than 10⁶. Since checking this generalized Chowla's hypothesis is easy to program and relies only on exact computation with rational integers, we do think that it should be part of any numerical computation verifying that L(s, χ) > 0 for s > 0 for real Dirichlet characters χ. To date, this verification for real, even and primitive Dirichlet characters has been done only for conductors less than 2·10⁵.

The proportion of people who contacted pulmonary T.B. in Korea has drastically decreased as a result of the incessant effort of the Korean government which adopted a policy of“drive out T.B.”as its foremost health policy. However, the proportion still remains relatively high com-pared with that of developed countries. This study attempts to find some means for guiding and educating college students who have T.B. in their health care by (1) first determining the effect if their self-concept and health beliefs on their behavior in regard to their disease and (2) then predicting the level of compliance of the new patients to the treatment suggested by the health specialist, before the commencement of the treatment. The subjects of this study consisted of 88 mald and female students at Y University who were diagnosed as minimal pulmonary T.B. patients and registered at the health clinic of Y University during the period between September 1, 1981 and March 31, 1953. Data were collected from them by means of questionnaire and interview. The instruments used for this study were (1) a part of Junghoon Choi's“Perceptual Orientation ,Scale”for measuring self-perception of patients and (2) Rosenberg's questionnaire for measuring patients' evaluation of self-esteem, and (3) an instrument for measuring patients' health beliefs which was developed by this researcher utilizing information available from references. The collected data were analyzed using descriptive statistics, chisquare test, Pearson correlation coefficient and t-test. The findings were as follows: 3. Test of hypotheses 1) Hypothesis 1: Patients with high self-concept will be high in health beliefs. For testing this hypothesis a calculation of Pearson correlation coefficient (r) between the patients' self-concept and their health beliefs was carried out. The result of this test was -. 0756 which was not significant at α=.05 and hence hypothesis 1 was not supported. 2) Hypothesis 2: Patients with a high self-concept will tend to be high in compliance with the suggested treatment. Again a Pearson correlaton coefficient was calculated between the two variaibles in the hypothesis. The calculated coefficient r was .1558 which was not significant at α=.05. Hence hypothesis 2 was rejected. 3) Hypothesis 3: Patients with high susceptibility will have a high compliance level. The correlation coefficient between the two variables was -.1975, which was significant at α=.05 but due to the negative sign hypothesis 3 could not be accepted. 4) Hypothesis 4: Patients who take their disease seriously will have a higher compliance level. The calculated correlation coefficient between the variables in this hypothesis was .1642 which was not significant at α=.05 and hence hypothesis 4 was rejected. 5) Hypothesis 5: Patients with a high sense of the benefit of treatment will have a high level of compliance. The computed correlation coefficient was .3129 which was significant at α=.05 and hence hypothesis 5 was acepted. 2. Findings from the correlation analysis were as follows: 1) Patients' susceptibility and their compliance to treatment was negatively correlated (r= -. 1975) which was significant at α= .05. This implies that as the patients' level of susceptibility increases their compliance level decreases. 2) Patients' susceptibility and their self-concept were negatively correlated (r= -. 1790) which was again singnificant at α=.05. The implication of this is that as the patients’self concept increases their susceptibility to disease decreases. 3) Patients' self-concept and their sense of benefit derieved from the treatment was positively correlated (r=.1970) which was significant at α=.05. That is, patients with a high self-concept perceived a great sense of benefit from the treatment. To summarize, patients who are low in susceptibility have a high level of compliance and self-concept.
