There exist many real situations that statistical decision problems are classified into more than two categories. In these cases, the concordance statistics by the pair approach are mostly used. However, the expression of the classification of categories are ambiguous. Recently, the standardized evaluation data and re-expressed concordance statistics are defined and could be explained their meanings. They have still some non-specific problems for standard criteria of the statistics. Since these can be considered between result and truth categories additionally, two alternative concordance statistics might be proposed in this paper. Some advantages are founded that the proposed statistics could be discriminated all possible cases for two randomly selected categories. Moreover since the proposed statistics are represented with indicator functions, these could be transformed non-parametrically, so that these concordances are used for hypothesis testing.

The gist of a scene can be identified in less than 100msec, and violation in the gist can influence the way to allocate attention to the parts of a scene. In other words, people tend to allocate more attention to the object(s) inconsistent with the gist of a scene and to have better memory of them. To investigate the effects of contextual consistency on the attention allocation and object memory, two experiments were conducted. In both experiments, a $3{\times}2$ factorial design was used with scene presentation time(2s, 5s, and 10s) as a between-subject factor and object-background contextual consistency(consistent, inconsistent) as a within-subject factor. In Experiment 1, eye movements were recorded while the participants viewed line-drawing scenes. The results showed that the eye movement patterns were different according to whether the scenes were consistent or not. Context-inconsistent objects showed faster initial fixation indices, longer fixation times, more frequent returns than context-consistent ones. These results are entirely consistent with those of previous studies. If an object is identified as inconsistent with the gist of a scene, it attracts attention. Furthermore, the inconsistent objects and their locations in the scenes were recalled better than the consistent ones and their locations. Experiment 2 was the same as Experiment 1 except that a dual-task paradigm was used to reduce the amount of attention to allocate to the objects. Participants had to detect the positions of the probe occurring every second while they viewed the scenes. Nonetheless, the result patterns were the same as in Experiment 1. Even when the amount of attention to allocate to the scene contents was reduced, the same effects of contextual inconsistency were observed. These results indicate that the object-background contextual consistency has a strong influence on the way of allocating attention and the memory of objects in a scene.

There are many situations that the outcome for clinical decision and credit assessment should be predicted more than two categories. Five kinds of statistics which are used the concordance are proposed and used for these polytomous problems. However, these statistics are defined without exact distinction of categories, so that we have difficulty to use both the pair and set approaches and it is hard to understand the meanings of these statistics. Hence, it is not possible to compare and analyze them. In this paper, the polytomous confusion matrix is standardized and the concordance statistic can be represented based on the confusion matrix. The five kinds of statistics by using the concordance are defined. With the methods proposed in this paper, we could not only explain their meanings but also compare and analyze these statistics. Based on various data sets, properties of these five statistics are explored and explained.

본 연구는 효율적 인적자원관리의 실행과 유지에 있어서 '일과 삶 균형(WLB: Work-Life Balance)' 정책의 중요성을 이론적·실증적 접근방식으로 규명하고자 하였다. 특히 본 연구에서는 WLB 정책을 유연근무제, 친가족정책, 개인신상지원 프로그램 등 3가지 차원으로 구분하여 제시하였으며, 분석대상을 공공조직과 민간조직으로 구분하여 기존 연구와의 차별화를 도모하였다. 연구모형 개발과 가설검증을 위해 제3차 여성가족패널(KLoWF) 자료를 바탕으로 WLB 정책과 정책 부합성, 직무만족도, 이직의도 간의 관계를 분석하였으며, 설문조사를 통한 양적 분석의 한계를 보완하기 위하여 공공조직 및 민간조직 여성 근로자와의 심층 인터뷰를 통한 질적 분석을 병행하였다. 분석결과, WLB 정책과 조직 효과성 간의 관계에 있어 공공조직과 민간조직 간의 유의미한 차이가 있음을 확인할 수 있었으며 심층 인터뷰를 통해 이러한 결과가 공공조직과 민간조직의 상호 이질적인 조직 문화, 제도, 구조적 특성에 기인하고 각 영역 구성원들의 서로 다른 욕구 및 동기 유발 체계에 의한 것임을 발견할 수 있었다. 이러한 분석결과를 바탕으로 본 연구에서는 각각의 조직 특성에 맞는 수요자 친화형 WLB 정책 구축의 필요성을 제안하고, WLB 정책 시행 측면의 문제점 및 개선방안 등을 제시하였다.

정보화의 진전과 더불어 삶의 편이성은 증대되고 있으나 개인과 조직은 물론이고 국가에 이르기까지 정보보안 사고로 피해와 고통 또한 증대되고 있는 실정이다. 이러한 사고로 인한 피해를 사전에 예방하거나 사후 손실을 최소화하기 위해서는 적절한 관리가 필요하며 이를 위해서는 무엇보다 실용적인 정보보안 평가지표의 개발이 필요하다. 본 연구에서는 정보보안을 대표하는 문헌을 참조하여 평가지표를 도출하고, 일련의 부합성 분석을 통해 보다 실용적인 정보보안 평가지표를 도출하여 제시하고자 한다.

The studies of congruence in organizational research have explored the concepts such as person-job fit person-organization fit, or person-environment fit. The relevant studies dealt with the fit level as an important influencing factor on the performance. In particular, researchers have agreed that employees can be motivated by the high level fit of person-organization. However, few research developing an alternative methodological approach has been done. For the purpose mentioned above the statistics like D, |D| or $D^2$ and the Q values such as Q(the correlation between two sets of interval measures) or $Q_r$(the correlation between two rankings) have been conventionally adopted in spite of numerous methodological problems. In general, these traditional indices such as difference scores, or Q values, are nondirectional and add an extra weight to differences of lager magnitude. Therefore, Edwards (1993) introduced the polynomial regression and the response surface analysis to overcome flaws with conventional approaches. However, the method-ological approaches did not reflect the profile characteristics of person-organizational value fit and wouldn't be a proper solution for the fit level of person-organization value maximizing performance. Hence, this paper investigates alternative methodological approaches, the multivariate polynomial regression and the multiple response surface analysis, to avoid the problems issued from conventional ways.

This study analyzed Korean representative ideology to establish a service philosophy. As a follow - up study of the service philosophy consistency study of the Korean original idea, we searched for the coherence as the philosophy of the service age in the Korean representative ideology. The basic structure and operation model of service philosophy are presented, and the service philosophy of major korean ideology is derived. The philosophy of service can be presented by the structure of service and the operation of service. The essential characteristics of the service are relationship, interactivity, horizontality, and harmony, and the service structure that reflects this is the coexistence of products and services. Based on the discussion on the structure and operation of the service philosophy, the service philosophy synthesis of Korean representative ideology is presented. From the Silla era to the Koryo dynasty, the essence of Korean Buddhism thought is in line with the service philosophy, and it was found that Toegye and Yulgok to Dasan's thoughts are also consistent with service philosophy. In the future, we need further studies to refine the structure and operational principles of the service philosophy and to develop it into a big idea. In addition, it is necessary to follow up the service philosophy of Oriental representative ideology centering on Chinese and Indian philosophy. Ultimately, it is necessary to establish a service philosophy as the main philosophical thought and to establish a service philosophy as a desirable future economic and social philosophy.

This study suggests the adjustment method of cadastral non-coincidence using spatial data referenced digital cadastral map and a present state. In designing the methodology, we should introduce the semi-automatic method for guaranteeing the stability and the accuracy at the arrangement of cadastral non-coincidence based on some cadastral specialist. This study could mainly show you rotation type, bias type, and rotation/bias type among cadastral non-coincidence types. We selected the matching reference point through the prototype system which automatically arranges in the study area. And then, we analysis the optimum rotation ratio(-0.4%). Finally, this paper show you calibrating cadastral non-coincidence using the rotation ratio. The methodology of this study has a limitation for arranging in case of cadastral non-coincidence by the area variation and some irregular types with unknown reason. Therefore, this case should be surveyed in direct method.
