It is now a well established fact that galaxies undergo significant morphological transformation during their lifetimes, manifesting as an evolution along the Hubble sequence from the late to the early Hubble types. The physical processes commonly believed to be responsible for this observed evolution trend, i.e. the major and minor mergers, as well as gas accretion under a barred potential, though demonstrated applicability to selected types of galaxies, on the whole have failed to reproduce the most important statistical and internal properties of galaxies. The secular evolution mechanism reviewed in this paper has the potential to overcome most of the known difficulties of the existing theories to provide a natural and coherent explanation of the properties of present day as well as high-redshift galaxies.

This study investigated the relationship of demographic and psychological variables with job and family-related stress among 293 employed wives. We found that age, job types, working in weekend, and family cohesion significantly contributed to the explanation of job-related stress. We also found that job types, working in weekend, family adaptation, family cohesion, and employment motivation significantly contributed to explaining the variation of family-related stress. Job-related stress was more explained by demographic variables than psychological ones, whereas family-related stress was more explained by psychological variables than demographic ones. Practical implications of the current findings were discussed.

As interest grows in nursing-wear in accordance with dissemination of breast-feeding, a study on opening of nursing-wear is needed to enhance convenience of breast-feeding regardless of location. In this study, the items on nursing-wear were classified and each characteristic was analyzed. The types and characteristics of opening on nursing-wear were identified and the characteristics of nursing brassier closely related to the nursing-wear were also identified. Top 5 companies for the nursing-wear and nursing-brassier were selected by ranking top 5 in NAVER with the search word 'nursing-wear' and 'nursing-brassier'. 732 one-piece and top (t-shirt and blouse) which have the highest portion in the nursing-wear were selected as the subject. Based on the photo, product explanation on the internet and in-depth interview of designer, the types and characteristics of openings for each item were identified. 732 nursing-brassier were selected to study the types and openings in breast-feeding. The result is as follows. Firstly, the item of nursing-wear can be classified into top, one-piece, package of top and the bottom, and sleeveless. Top and one-piece have the highest production rate. Secondly, the types of the openings are either covering or opening types. There are vertical-slit and horizontal-slit in covering type, and vertical-zipper, horizontal-zipper, and button types in opening type, and overlap and pocket type for the rest. Thirdly, the commercially available nursing-brassier according to the opening manner can be classified into upper-opening, middle-opening, and overlap types. Most largely produced product is upper-opening type as it minimizes the exposure of the breast in breast-feeding. When producing the nursing-brassier, the measurement of the lower breast and cup size are considered.

Purpose: Previous studies have shown that consumers feel more happiness when they have experiential purchases than material purchases. This experiential advantage has aroused great concern of researchers in the field of social and consumer psychology. Focusing on this issue, the paper aims to tease out the relevant academic work and to further provide with some significant implications. Research design, data and methodology: The paper has divided the review into the following parts. Firstly, the connotation of experiential purchase and material purchase has been simply defined; Secondly, based on the logical framework of pre-factor variables, intermediary variables and regulating boundary conditions, this paper has collated the causal chain of the influence of purchases types on happiness; Finally, this paper has reviewed and summarized the shortcomings of existing studies, and have pointed out specific objectives of future research. Results: From the perspective of time utility and space form, this paper has expounded the substantive differences between the two types of purchase, which lays a foundation for the explanation of the follow-up mechanism. Moreover, the paper has mainly interpreted the intermediary mechanism from two aspects, namely, individual elements of consumers and social elements of consumption situations. Conclusions: This study expands the scope of previous happiness research and strengthens the negative events adaptation research.

Researchers have employed a diversity of definitions and measurement methods for creativity. As a result, creativity research is underrepresented in the literature and the findings of different studies often prove difficult to draw into a coherent body of understanding. With regard to assessment, there are some important problems both in creativity research and practice, such as originality bias and Big-C creativity bias in teachers' perceptions about creativity and creative thinking, and additive rather than multiplicative scoring systems of creativity assessment. Drawing upon most widely accepted conceptions of the creativity construct, I defined 'student's scientific creativity' as the ability to make a product both original and useful to the student in terms of little-c creativity, and 'scientist's scientific creativity' as the ability to come up with a product both original and useful to the science community in terms of Big-C creativity. In this study, an 'Assessment Formula for Scientific Creativity' was developed, which is consisted of the multiplication of originality and usefulness scores rather than the sum of the two scores, and then, with scores calculated from the assessment formula, the scientific explanations generated by children were categorized into four types: routine, useful, original, and creative types. The assessment formula was revealed to be both valid and reliable. The implications of the assessment formula for scientific creativity are examined. The new assessment formula may contribute to the comprehensive understanding of scientific creativity to guide future research and the appropriate interpretation of previous studies.

This study examined the expression mode and feature about photomontage indicated in the 21st century's Contemporary fashion. This intends to have better understanding on photomontage and to provide theoretical explanation to help a creative design development using photomontage in the future. For the research method, review over photomontage concept and its historical background was carried out with relevant literature and precedent studies. Then, analysis was followed about 258 pieces of photomontage application works featured in the four major global collections from 2001S/S to 2011F/W. Among types of photomontage expression in the Contemporary fashion, objects in the nature like animal, plant, scenery picture took up the highest frequency as motive. Other types appeared in the following order: the people-oriented type such as eminent person's figure or partial body, the ready-made image including diverse daily goods in the modern consumption society, a variety of printed stuff like cartoon, newspaper and magazine, the type of photomontage expression through borrowing the earlier famous art pieces or doing the cooperative work with artists in different fields, applications like architecture, land marks in many cities in the world, and interior, things assembled with various images, modified religious images in photomontage from Buddha or holy picture. Therefore, the modern fashion that uses photomontage could possibly feature popularity, naturalism, playfulness and creativity.

This study was done to analyze the trends of research on coping in Korea, to suggest future direction, for research on coping, and ultimately to contribute to an increase in explanation of adaptation. This article reviewed 79 nursing research papers on coping done since 1978 by examining them according to the period of publication or presentation, research design, type of subjects, measurement instruments, research for a degree or not, range of reliability, and association of coping and related variables. The results are as follows : The number of studies on coping increased rapidly from the mid-1980's and decreased slowly from the mid-1990's. The maority of the studies were surveys, comparative studies, or correlational studies. The subects of the 46 studies were healthy people, while those in the remaining studies were patients with a variety of illnesses. Thirth-eight studies on coping were done for master's thesis, three for dissertion, and 38 were not degrees. The Bell and Jalowiec coping scales have not been used since the early 1990's. In contrast, Lazarus and Folkman's W.C.C.L. has been used increasingly since that time. The reliabilities of the coping scale were reported in 37 cases and the Cronbach's alpha coefficients were .71 to .86. All subjects reported using more problem-oriented coping than emotion-oriented coping in short-term or emotion-oriented coping and healthy groups did more long-term coping. It was difficult to describe consistently the relationship between stress and coping according to the type of coping scale or research subjects, but generally moderate relationships were found. This was due to instrumental problems and no consideration of situational context. The subject group who used more short-term coping and less long-term coping reported poorer mental status, and higher scores in burnout and state anxiey than others. That is, the relationship between stress and adaptation increased the power of explanation with intervening the mediating effect of coping. The association of locus of control, mastery, social support, and self-concept with coping showed positive relationships : those of uncertainty and severity in illness with coping showed negativerelationships ; those of state anxiety and depression with short-term coping were positive, and those of self-esteem with long-term coping or problem-oriented coping were negative. There were significant differences in the scores of types of coping according to religion, level of education, and socio-economic status. That is, Presbyterians and Catholics, those with higher education levels and higher socio-economic status used more long-term or problem-oriented coping. On the basis of the above findings the following recommendations are made : 1. There is a need to test the mediating effect of coping variable in order to clarify the concept. 2. Longitudinal studies are needed to determine the patterns of change in coping strategies when stressful events are encountered. 3. It's necessary to develop a reliable and variable measurement tool for coping. 4. There is a need to identify subscales of coping to increase explanation of variance 5. It's necessary to consider personal, situational, and antecedent variables : the characteristics of subject populations, the natures of illness and treatment situations. 6. The power of explanation of studies designed to identify the stress-adaptation process should be increased using the combination model of process-oriented coping and cognitive-structural model.

이 연구에서는 어는점 내림에 대한 과학교과서의 설명 방식과 과학 교사들의 개념을 조사하였다. 분석한 교과서는 7차 교육과정에 근거하여 개발된 중학교 2학년 과학교과서 7종과 고등학교 화학 II 교과서 5종이었다. 교사들의 개념은 설문지를 통해 얻었으며, 연구 대상 교사의 수는 146명이었다. 교과서의 설명 유형은 '현상을 묘사' 하는 것과 '증기압 내림으로 설명' 하는 유형으로 구분하였다. 대부분의 중학교 교과서와 고등학교 교과서에서는 현상을 묘사하는 수준으로 어는점 내림을 설명하였으며, 이러한 현상이 일어나는 이유에 대한 설명은 없었다. 또한 어는점 내림을 설명하는 그래프의 내용도 교과서마다 달랐다. 교사들 역시 어는점 내림에 대해 제대로 이해하지 못하는 것으로 나타났다. 용질의 방해로 어는점 내림 현상을 이해하는 교사들도 많았다. 그러나 끓는점 오름 현상을 설명할 때 도입되는 이러한 개념이 어는점 내림에서는 어떻게 관련되는지 명확하게 설명하지 못하였다. 이 연구에서는 어는점 내림 현상을 설명하기 위하여 엔트로피의 개념을 도입할 필요성에 대해 주장하였다.

이 연구에서는 2015 개정 교육과정에 따른 중학교 과학과 교과서의 물질 단원에 제시된 시각적 입자 표상의 활용 방식을 분석하였다. 4종의 과학 교과서의 물질 단원을 설명, 탐구, 평가 영역으로 구분하고 제시된 시각적 입자 표상의 활용 형태, 요구되는 활동 방식, 활동 수준을 분석하였다. 설명 영역의 경우 시각적 입자 표상은 주로 보조적 활용 형태로 제시되었으며 탐구와 평가 영역의 경우 직접적 활용 형태로 주로 제시되었다. 직접적 활용의 시각적 입자 표상의 활동 방식은 설명과 평가 영역에서는 주로 해석하기가, 탐구 영역에서는 다른 두 영역에 비해 완성하기와 생성하기가 비교적 높은 비율로 제시되었다. 활동 수준의 경우 설명 영역에서는 찾기 수준이, 탐구와 평가 영역에서는 유추하기 수준이 주로 나타났다. 이상의 결과를 바탕으로 과학 교과서 속 시각적 입자 표상의 제시와 활용 방향에 대한 시사점을 논의하였다.
