In this paper, we generalize the concept of deferred density to that of deferred f-density, where f is an unbounded modulus and introduce a new non-matrix convergence method, namely deferred f-statistical convergence or $S^f_{p,q}$-convergence. Apart from studying the $K{\ddot{o}}the$-Toeplitz duals of $S^f_{p,q}$, the space of deferred f-statistically convergent sequences, a decomposition theorem is also established. We also introduce a notion of strongly deferred $Ces{\grave{a}}ro$ summable sequences defined by modulus f and investigate the relationship between deferred f-statistical convergence and strongly deferred $Ces{\grave{a}}ro$ summable sequences defined by f.

In this paper, the classical Irons' patch tests which have been generally accepted for the convergence proof of a finite element are performed for Mindlin plate bending elements with a special emphasis on the nonconforming elements. The elements considered are 4-node and 8-node quadrilateral isoparametric elements which have been dominantly used for the analyses of plate bending problems. It was recognized from the patch tests that some nonconforming Mindlin plate elements pass all the cases of patch tests even though nonconforming elements do not preserve conformity. Then, the clues for the Mindlin plate element to pass the Irons' patch tests are investigated. Also, the convergent characteristics of some nonconforming Mindlin plate elements that do not pass the Irons' patch tests are examined by weak patch tests. The convergence tests are performed on the benchmark numerical problems for both nonconforming elements which pass the patch tests and which do not. Some conclusions on the relationship between the patch test and convergence of nonconforming Mindlin plate elements are drawn.

The purpose of this study is to figure out how factors of internal marketing affect service quality. Method of human resource could be indicated to bear fruit of food-industry based on this research. This study conducted documentary study and empirical study. To achieve the purpose, a survey was conducted by 229 staffs of family restaurants in Daegu. The result of this research is as follows. First, the properties of each factor of internal marketing, Service Quality and staff's behavior were extracted from the previous studies. Second, internal marketing was applied as a independent variable, and service Quality as a consequent variable. The result reached through convergent validity came to satisfy all variables. Third, it was strongly maintained the fact that the better internal marketing was applied, the more staff were satisfied and the higher service quality was. It was shown that staffs provided customers with a good service if they were satisfied with internal marketing and their companies.

The effects of nozzle-lip thickness on the relationship between screech tone and broadband shock-associated noise were experimentally investigated using a convergent-divergent nozzle with a design Mach number of 2.0. Overall sound pressure levels (OASPL) and noise spectra were obtained at far-field locations. Schlieren optical system was used to visualize the flow-fields of supersonic jets. A baffle plate was installed at the exit of the nozzle and its size was varied to obtain different nozzle-lip thicknesses. Experiment was carried out over a wide range of nozzle pressure ratios from 2.0 and 18.0, which corresponds to over- and under-expanded conditions. The results obtained clearly show that the screech tones are influenced by the nozzle-lip thickness. It is found that the screech tone and its peak amplitude are strongly dependent on whether the jet is over-expanded and under-expanded at the nozzle exit.

인터넷 비즈니스나 전자상거래와 연관되어 고객관계관리 (Customer Relationship Management: CRM)가 널리 확산됨으로 해서 군집분석에 대한 관심이 한층 높아졌고, 다양한 군집분석 프로그램이 시장에 소개되어 지고 있다. 그러나, 군집분석 프로그램들은 다른 데이터 분석 기법과는 달리 그들의 정확성을 측정하기가 매우 힘들다. 본 논문에서는 이미 알려져 있는 군집구조를 지닌 인위적 데이터를 사용하여 반복적 군집분석 프로그램 (Convergent Cluster Analysis: CCA)과 보다 전통적인 단순군집 프로그램 (One-Shot Clustering Program: Howard-Harris 프로그램), 그리고 데이터 마이닝 기법 중의 하나인 데모그래픽 군집분실 프로그램의 정확성을 비교하기 위한 현재 진행 중인 연구의 방법론을 제시하는데 그 주요 목적을 두고 있다.

In addition to exceptional abilities and domain-specific aptitudes, frequently creativity potentials are used to explain high achievements in science and technology. In the Guilford tradition, research focuses increasingly on convergent versus divergent thinking, that is, a suspected dichotomy between intelligence and creativity. Despite important insights from this about relationship of ability and creativity, a number of important questions remain unanswered. These relate not only to conceptualization and measurement problems regarding the hypothetical constructs "scientific ability" and "creativity", but also their diagnosis and nurturance in childhood and adolescence. It would appear that, in view of current research paradigms, the role of ability and creativity needs to be redefinded in order to more reliably predict and explain excellent achievements in science and technology. Advances are mostly expected from synthetic approaches. Thus, I will be presenting new theoretical models and empirical research results. Finally, consequences for the prediction and promotion of mathematical-scientific and technical talents will be discussed including the consideration of sex-related problems.

Purpose - Recently, the management conditions of small independent retailers are getting worse everyday as large-scale marts and franchised convenience stores are increasing. The objective of this research is to find out the antecedents and consequences of cooperation in voluntary chain in order to enhance small independent retailer's competitiveness. Voluntary chains, also called affiliation or symbol groups, or allied group represent a high market shared in some European countries like Italy, France, and Germany. Nevertheless, there are still limitations in this research from academic fields. Drawing from network theory, the author investigates the relationship between antecedent factors in voluntary chain cooperation, such as participation benefits, justice of compensation, and autonomy in voluntary chain, and relationship specific asset. The author also attempts to examine the relationship between the relationship specific asset and cooperation of voluntary chain member shop and cooperation and consequence factors of voluntary chain cooperation, such as efficiency, group cohesiveness, and long-term relationship. Research design, data, and methodology - The author presented conceptual framework integrating the major antecedents and consequences of voluntary chain cooperation. The data were collected from 174 independent small retailers who joined K-voluntary chain. K-voluntary chain consists of small independent retailers. In accordance with their status, each entrepreneur associated with the voluntary group can own one or more outlets and can be a part of the life and the decision-making process of the group. This participation is not based on company turnover or on the number of outlets, but based on a one member, one vote system. To verify the research model and test hypotheses, the author carefully investigated the reliability, content validity, convergent validity, and discriminant validity of the proposed model. The data were analyzed by using SPSS 18.0 and AMOS structural equation modeling program. Results - The results of this study are as follows. First, as antecedent variables, participation benefits and justice of compensation have positive effect on the relationship specific assets of voluntary chain members. Second, voluntary chain members' relationship specific asset also directly related to the level of its cooperation to chain headquarter. Third, cooperation of voluntary chain member shop facilitates efficiency, group cohesiveness, and long-term relationship. Unexpectedly, there are no effect autonomy in voluntary chain to relationship specific asset. Conclusions - This research shows several theoretical and practical implications to both marketing scholars and marketers. In terms of theoretical implications, this study applies to network theory and network theory variables to explain the antecedent and consequence factors of cooperation in voluntary chain. From the point of view from business management, most of all, this study shows the way how to reinforce competitiveness of voluntary chain. Specifically, it is necessary for voluntary chain headquarter to give higher level of participation benefit and justice of compensation to its members. Second, the results also indicate what the consequence factors of cooperation in voluntary chain. In other words, to increase the level of marketing efficiency, group cohesiveness, long-term orientation in retail voluntary chain, and chain headquarter need to facilitate participants' cooperation.

The study analyzed convergent influence on occupational stress(KOSS-SF: Korean Occupational Stress Scale-Short Form) and its association with Organizational Justice(OJ), Self Esteem(RSE :Rosenberg Self-Esreem) and Self Efficacy(GSE: Generalized Self-Efficacy) among some regional General Hospital Administrative Staff(GHAS). The survey was administered to 221 staff from 11 general hospitals located in J city from Nov. 1st, 2016 to Jan. 31st, 2017, by structured self-administered questionaries. Occupational stress was negatively correlated with two sub-domains of OJ, RES and GSE. With the analysis of covariance structure, we identified the causal relationship of OJ, RES, GSE and occupational stress among GHAS. The study found the higher OJ, RES and GSE tend to decrease occupational stress. The results indicate that the efforts, to increase OJ, RSE and GSE, are required to decrease the occupational stress of GHAS. The results are expected to be useful for organization & HR management to decrease the occupational stress of GHAS. In the following study, the analysis about convergent additional factors of influence on occupational stress of GHAS will be needed.

This study investigates convergent influence on depression and its association with positive emotion, negative emotion and job seeking stress among some college women of health affiliated educations. The survey was administered to 419 college women in Honam area from March 9th to April 30th, 2015. The structured self-administered questionaries were used. The depression was negatively correlated with positive emotion and it was positively correlated with negative emotion and job seeking stress. The results of hierarchical multiple regression analysis show the following. The depression of respondents turned out to be significantly higher in following groups: a group in which self esteem is lower, a group in which subjective happiness is lower, a group in which hopelessness is higher, a group in which type A behavior pattern is higher, a group in which personality stress is higher. Their explanatory power was 47.1%. With the analysis of covariance structure, we could confirm relationship among the four factors such as positive emotion, negative emotion, job seeking stress and depression. In conclusion, the results of the study indicate that the efforts, to increase positive emotion, and to decrease negative emotion and job seeking stress, are required to reduce the depression level of the college women of health affiliated educations.
