From the notion of bi-ideals in near-rings, various generalizations of regularity conditions have been studied. In this paper, we generalize further the notion of bi-ideals and introduce the notion of weak bi-ideals in near-rings and obtain some characterizations using this concept in left self distributive near-rings.

The notion of bi-ideals in near-rings was effectively used to characterize the near-fields. Using this notion, various generalizations of regularity conditions have been studied. In this paper, we generalize further the notion of bi-ideals and introduce the notion of weak bi-ideals in near-rings and obtain various characterizations using the same in left self distributive near-rings.

Two measures of distributive mixing are examined: the standard deviation $\sigma$ and the maximum error E, among average concentrations of finite-sized samples. Curves of E versus sample size L are easily interpreted in terms of the size and intensity of the worst flaw in the mixture. E(L) is sensitive to the size of this flaw, regardless of the overall size of the mixture. The measures are used to study distributive mixing for time-periodic flows in a rectangular cavity, using the mapping method. Globally chaotic flows display a well-defined asymptotic behavior: E and $\sigma$ decrease exponentially with time, and the curves of E(L) and $\sigma$ (L) achieve a self-similar shape. This behavior is independent of the initial configuration of the fluids. Flows with large islands do not show self-similarity, and the final mixing result is strongly dependent on the initial fluid configuration.

본 연구의 목적은 공정성의 결과변수로서 직무만족, 잔류의도, 조직몰입 및 조직시민행위의 네 측면에서 분배공정성과 절차공정성이 MICE산업종사자들의 직무태도에 미치는 차별적 영향을 탐구하는데 있었다. 본 연구를 위한 자료는 수도권 소재 30개 MICE업체 종사자 303명으로부터 수집되었다. 자료수집도구로는 자기기입식 설문서를 사용하였으며, 자료분석은 위계적 회귀분석방법을 사용하였다. 연구결과 MICE산업종사자들의 직무만족에 대해서는 절차공정성보다는 분배공정성이 더 큰 영향을 미치는 반면, MICE산업종사자들의 잔류의도, 조직몰입 및 조직시민행위에 대해서는 분배공정성보다는 절차 공정성이 더 큰 영향을 미친다는 것을 보여주었다. 또한 절차공정성의 조절효과는 MICE산업종사자들의 직무만족 및 조직몰입과 관련해서는 절차공정성의 조절효과가 나타나지 않은 반면, MICE산업종사자들의 잔류의도 및 조직시민행위에 미치는 분배공정성의 긍정적 영향은 절차공정성이 높을 때 더욱 커지는 것으로 나타났다. 이러한 연구결과가 분배 및 절차공정성의 관계 및 역할과 관련한 두 요인모형, 문화적 모형 및 상호작용모형에 대하여 갖는 이론적 함의를 논의하고, 향후 연구방향을 제시하였다.

We say that (R, f, g) is an additive (m, n)-semihyperring if R is a non-empty set, f is an m-ary associative hyperoperation, g is an n-ary associative operation and g is distributive with respect to f. In this paper, we describe a number of characterizations of additive (m, n)-semihyperrings which generalize well-known results. Also, we consider distinguished elements, hyperideals, Rees factors and regular relations. Later, we give a natural method to derive the quotient (m, n)-semihyperring.

본 연구는 최고경영자신뢰와 상사신뢰를 구분하고, 이러한 신뢰의 유형이 조직공정성과 종업원 행동 간의 관계에 미치는 매개효과를 구조방정식모형으로 검증하였다. 국내 18개 회사 4,055명을 대상으로 자기보고식 설문조사를 실시하고 AMOS 구조방정식 모형으로 분석하였다. 연구결과, 분배공정성과 절차공정성 모두 상사신뢰보다 CEO신뢰에서 높은 상관을 보였다. 또한 CEO신뢰와 상사신뢰는 조직공정성과 종업원 행동 간의 관계를 완전매개 하였다. 특히 절차공정성은 분배공정성 보다 CEO신뢰와 상사신뢰에 더 큰 영향을 미치는 것으로 나타났다. 그러나 신뢰의 유형이 종업원 행동에 미치는 영향은 차이가 없는 것으로 나타났다. 미지막으로 연구결과를 토대로 본 연구의 학문적 의의 및 실무적 시사점 그리고 제한점과 미래연구 과제에 대해 논의하였다.

The purpose of this study is to develop instruction model of environmental problem process focused with environmental justice. This study has analyzed environmental problem solution process in social studies of elementary school from 4th grade to 6th grade with it. The results of this study are as follows. First, social studies of elementary school didn't show distributive justice in environmental problem solving process. Second, procedural justice existed, but offered information is lacking to each main group. Third, substantive justice was emphasized personal viewpoint. We developed instruction model of environmental problem solving process based upon the results. Component of instruction model is problem analysis, distributive justice, procedural justice, substantive justice and evaluating a solution. Timely, teachers can use and can apply it in social studies class. In conclusion, it is strongly recommend to teach environmental education linked with environmental justice. It enables us enhance a new awareness and attitudes towards sustainable development.

The purposes of this study are to explore how the service recovery of the beauty shops and customers' perceived justice affect the customer relationship. A survey based questionnaire method was employed for this study. Data were collected by a convenient sampling of 232 female customers of hair beauty shops in Seoul and Busan. The data were analysed by using SPSS 21.0, including a frequency analysis, reliability analysis, factor analysis and multiple of regression analyses. The first result showed that all dimensions of service recovery had a significantly positive effect on the perceived justice. Especially, behavioral recovery of beauty shops was the major significant factor affecting perceived justice. Second, distributive justice and interactive justice had a significant effect on satisfaction. However, procedural justice did not have any significant effect on satisfaction. Finally, satisfaction was significantly and strongly associated with both trust and commitment. These results provide empirical proposition that the recovery strategies for complaint handling of the beauty service shop are related closely to relationship marketing.

This study is conducted to examine the relationship between salespeople's job consciousness, their competencies of practical business and their turnover intention in department stores. The data was collected from 1961 department stores salespeople in Seoul and Sungnam. And a survey was conducted by questionnaire. Mean, Scheffe-test, Cronbach's ${\alpha}$, Perason's correlation, factor analysis, regression analysis, path analysis are used for the analysis of data. Major findings are as follows : 1) Job consciousness of salespeople is relatively strong, the level of competencies of practical business and turnover intention are somewhat low. 2) Job consciousness of salespeople and their competencies of practical business are related to their turnover intention. The more strongly they have job consciousness, the more highly they have the level of competencies of practical business, and the lower their turnover intention becomes. 3) Among related variables, their perception of distributive education shows the strongest effect on job consciousness of salespeople. Their job consciousness shows the strongest effect on competencies of practical business. Their job consciousness and competencies of practical business show the strongest effect on turnover intention of salespeople. 4) Turnover intention of salespeople is affected by the job consciousness directly or indirectly, and by competencies of practical business directly. Among related variable, age, experience degree on distribution education, period of work, educational level, marital status, jobs, the motive of choosing their occupation and sex show only indirect effects on their turnover intention through job consciousness and competencies of practical business of salespeople. The motive of choosing their occupation, importance degree on distributive education, sections of department stores(Clothing), perception degree on job specialization and selling experience show only direct and indirect effects on their turnover intention. Thus, job consciousness and competencies of practical business of salespeople are the major intervening variables which have strong negative effects on their turnover intention.
