This study was about the fashion model's images during the periods of time. Also, this was to know the model's role and fields they had worked in and to investigate the specializing courses to get advice from their diversities, specialties and activities. The method of the study was used the qualitative analysis from the relative books, theses from university graduates, the related society newsletters, fashion magazines that were printed periodical/non-periodical, and others. As a result, the glamourous image was the most famous in the twenties and thirties, and the elegant image mainly in the forties and fifths. The images were more diverse in the nineties through the girlish images of the sixties, and the sexy image with good health of the seventies and eighties. Baby faces became the ideal of models in the new century. The images of the models become popular and disappear rapidly due to the change of major trend with the change of the society's environment. Under the situation, they must take good care of their images and self-control themselves to keep a positive view of fashion models to the public, and they must have ambition as a fashion icon and make their own exclusive fields in various parts.

The present paper investigated the effect of ultrasonic vibrations on the melting process of a phase-change material (PCM). Furthermore, the present study considered constant heat flux boundary conditions unlike many of the previous researches adopted constant wall temperature conditions. Therefore, in the present study, modified dimensionless parameters such as Ste* and Ra* were used. Also, general relationships between melting with ultrasonic vibrations and melting without ultrasonic vibrations were established during the melting of PCM. Experimental observations show that the effect of ultrasonic vibrations on heat transfer is very important throughout the melting process. The results of the present study reveal that ultrasonic vibrations accompany the effects like agitation, acoustic streaming, cavitation, and oscillating fluid motion. Such effects are a prime mechanism in the overall melting process when ultrasonic vibrations are applied. They enhance the melting process as much as 2.5 tildes, compared with the result of natural melting. Also, energy can be saved by applying ultrasonic vibrations to the natural melting. In addition, various time-wise dimensionless numbers provide conclusive evidence of the important role of ultrasonic vibrations on the melting phenomena.

In 21th century, climate change is one of the fundamental issue. Greenhouses gases are pointed as the main cause of climate change. Soil play a vital role of carbon sink and also can be a huge source of greenhouse gases defense on the management. Flux of greenhouse gases is not the only factor can be changed by climate change. Climate change can alter proper management. Temperature change will modify crop planting and harvesting date. Other management skills like fertilizer, manure, irrigation, tillage can also be changed with climate change. In this study, greenhouse gases emission in rice paddy in South Korea is simulated with DNDC model from 2011 - 2100 years. Climate for future is simulated with RCP 8.5 scenario for understanding the effect of climate change to greenhouse gases emission. Various rice paddy flooding techniques were applied to find proper management for future management. With conventional flooding technique, climate change increase greenhouse gases emission highly. Marginal flooding can decrease large amount of greenhouse gases emission and even it still increases with climate change, it has the smallest increasing ratio. If we suppose the flooding technique will change for best grain yield, dominant flooding technique will be different from conventional flooding to marginal flooding. The management change will reduce greenhouse gases emission. The result of study shows the possibility to increase greenhouse gases emission with climate change and climate change adaptation can show apposite result compared without the adaptation.

The stability of protein tissues and protein fibers in the human muscle is investigated in the presented paper. The protein fibers are modeled via tube structures embedded in others proteins fibers like the elastic substrate. Physical sport and physical exercise play an important role in the stability of synthesis and strength of the protein tissues. In physical exercise, the temperature of the body increases, and this temperature change impacts the stability of the protein tissues, which is the aim of the current study. The mathematical simulation of the protein tissues is done based on the mechanical sciences, and the protein fibers are modeled via wire structures according to the high-order theory beams. The thermal stress due to the conditions of the sport is applied to the nanoscale protein fibers, then the stability regarding the frequency analysis is investigated. Finally, the impact of temperature change, physical exercise, and small-scale parameters on the stability of the protein tissues are examined in detail.

Previous studies have established a role for cognitive differences in explaining variability in speech processing across individuals. In the case of perceptual cue weighting in the context of a sound change, studies have produced conflicting results regarding the relationship between executive function and the use of redundant cues. The current study aimed to explore this relationship in acoustic cue weighting during speech production. Forty-one Korean-speaking children read a list of stop-initial words and completed two tests that assess executive function, i.e., Dimensional Change Card Sorting (DCCS) and digit n-back. Voice onset time (VOT) and fundamental frequency (F0) were measured in each word, and analyses were carried out to determine the extent to which children's executive function predicted their use of both informative and less informative cues to the three pairs comprising the Korean three-way stop laryngeal contrast. No evidence was found for a relationship between cognitive ability and acoustic cue weighting in production, which is at odds with previous, albeit conflicting, results for speech perception. While this result may be due to the lack of task demands in the production task used here, it nevertheless expands the empirical ground upon which future work in this area may proceed.

This study is a descriptive study to provide basic data related to types of uniforms worn by nurses. Nurses, other medical center personnel, patients and their famillies were asked for their opinion on changing nurses’ uniforms and how the image of nurses is 1 elated to the type of uniform worn by the nurses. The data for this study were collected during the period from Feb. 25, 1993 to Mar. 26, 1993 at Y-University Medical Center from 132 nurses, 137 other medical center personnel, 117 patients and their families. The instruments used for this study were the Nurses’ Image Scale(NIS) developed by Bown(1986), and an instrument to measure opinions of uniform and cap using photographs of nurses’ uniforms that was developed by the researcher through a literture review. Data were analyzed using the SPPS / PC package, Statistics used for analysis were frequencies, percentages, paired t -test, and oneway ANOVA The results of this study are summarized as follows ; 1. Of the nurses, 84.3%, along with, 51.5% of the medical center personnel, 39.1% of the patients and their families agreed to a change in the color of nurses uniforms. 2. Similarly, 87.4% of the nurses,27.7% of the medical center personnel, 19.3% of the patients and their families were in favor of nurses not wearing caps. 3. Only 11.8% of nurses answered that a white uniform was important to the professional image of nursing. Only 2.4% of the nurses answered that a cap was very important to the professional image of nursing. 4. Only 1.6% of the nurses answered that a white uniform and cap were important to show the role of nurses in the twenty first century. 5. About 1/3, 36.5%, of the medical center personnel, the patient and their families answered that changing the color of the nurses' uniform will make a change in the image of nurses. 6. A White uniform and cap were seen as being im-portant in distinguishing nurses from other medical personnel in the hospital by 76.5% of the medical personnel, the patients and their families. 7. Nurses gave high marks to the idea of no cap regardless of the color of the uniform which would still portray the symbol of the nurses’ role, identity and would differentiate the role from other jobs. The patients and their families gave high marks to a white uniform with cap. 8. Generally, nurses, medical center personnel and patients and their families thought that a colored uniform with cap presented a good image of nurses. 9. There was a significant difference in the response among the three groups(F=24.65, P〈.001) to the figure in a white uniform with a cap, and the patients and their families thought it was the best portrayal of the image of nurses. There was a significant difference among the three groups(F=9.03, P〈.001) to the figure in a white uniform with no cap and the nurses indicated that it was the beat portrayed of the image of nurses. There was no significant difference among the three groups to the figure in a colored uniform with cap. There was a significant difference(F=17.50, P〈. 001) to the figure in a colored uniform with no cap, and the nurses indicated that it was the best portrayal of the image of nurses. In summary, the nurses wanted to change the color of uniform and not to wear a cap. But many of the medical center personnel, patients and their families indicated they did not agree with this idea. Therefore, changing the type of uniform worn by nurses should be done only after consideration has been given to the relation of the change to the professional role of nurses and the image of nurses held people in general. Suggestions arising from this study are as follows : 1. The relation between the role of nurses and their uniform was surveyed, and these results can be used as data when considering a change in uniforms. 2. A change in uniforms should be tried based on the norm established about uniforms. 3. The nurses did not want to wear a cap, but before a decision is definitely made it is necessary to study the philosophy related to the symbol of the cap because the figure of a nurse with a cap portrayed a positive image of the nurses. If the cap is kept, the symbol of the cap should be redefined. 4. In this study, only the image related to the uniform was examined, but in future studies it will be necessary to examine the practicality of various types of uniforms.

This paper presents the empirical research results conducted in a Swedish care organization for elderly and handicapped. The objective of the research was to empirically assess the implementation and practices of a quality system (ISO 9000) from an organizational change and development perspective. The empirical data were collected through multiple methods; interviews were carried out with key-persons and leadership in the organisation and surveys were conducted to all employees. Interactive methods have been applied to various groups in the organisations e.g., directors, supervisors, and the leadership of the quality project and the local politicians. The empirical findings indicate, among others, that the implementation processes were received and perceived differently in the different parts of the care organisation due to different leadership strategies and employee involvement policies. Other critical factors such as acceptance, resistance, motivation, commitment, the role of leadership, learning possibility, etc. have also been investigated, analysed and discussed. Finally some recommendations on how to approach organisational change as well as strategies for implementing a quality system in the care sector are presented.
