This study examined the changes in sleeping and studying patterns of young students and their mothers after moving to foreign countries. This study analyzed the relational characteristics of Geese Family members which are summarized as follows: 1) Sleeping Pattern: At the early stages of settling into foreign countries, students begin to sleep in the same bedroom with their mothers, who had used to sleep in separate bedrooms back in Korea. This change in pattern may slightly vary according to the age and gender of the students, and type of residence. Relationships between young students and mothers become more tightly coupled. However, relationships between students and fathers become less tightened. 2) Studying Pattern: Students tend to study in the public space such as the living room and dining areas, rather than in their own private rooms. This is because mothers want to support and focus upon their children's study by sacrificing normal family activities. These patterns appear stronger as their period of study in the foreign country becomes shorter and the ages of the students become younger. These studying patterns also contribute to the coupling between mothers and young students. 3) Family Relationships: From the period as Geese Families, the relation between mothers and young students become closer both physically and emotionally. The relation between fathers and children become less close. The role of fathers is degraded to that of supporter or negotiator for the time period of the mothers and child students in the foreign country.

The purpose of this study was to grasp the relationship among general characteristic, work characteristic, job stress and social psychological stress by targeting dental hygienists in a certain area. By using self-administered questionnaire, it was possible to get following results from 219 people. The total score of job stress of dental hygienist was $47.41{\pm}7.46$. The people who are younger, take lower positions at their workplace and not married showed higher stress about physical environment, autonomous work and improper compensation. The people with lower income showed higher stress about autonomous work and the people with lower academic background showed higher stress about physical environment and autonomous work. The people who spend more time at their workplace showed higher stress about autonomous work and showed lower stress about relational conflict, organization system, improper compensation and work culture. The job stress about physical environment, job request, autonomous work, unstable work, improper compensation and workplace culture had a positive correlation with social psychological stress. It was found that unstable work, organization system, improper compensation and higher position gave effects to social psychological stress.

In this paper, the WEKA platform was used to mine and analyze measured data of floor failure depth and a prediction system of floor failure depth was developed with Java. Based on the standardization and discretization of 35-set measured data of floor failure depth in China, the grey correlation degree analysis on five factors affecting the floor failure depth was carried out. The correlation order from big to small is: mining depth, working face length, floor failure resistance, mining thickness, dip angle of coal seams. Naive Bayes model, neural network model and decision tree model were used for learning and training, and the accuracy of the confusion matrix, detailed accuracy and node error rate were analyzed. Finally, artificial neural network was concluded to be the optimal model. Based on Java language, a prediction system of floor failure depth was developed. With the easy operation in the system, the prediction from measured data and error analyses were performed for nine sets of data. The results show that the WEKA prediction formula has the smallest relative error and the best prediction effect. Besides, the applicability of WEKA prediction formula was analyzed. The results show that WEKA prediction has a better applicability under the coal seam mining depth of 110 m~550 m, dip angle of coal seams of 0°~15° and working face length of 30 m~135 m.

The purpose of this study was to understand the lived experiences of grandmothers who provide child care services to their grandchildren and employed mothers who utilize child care by grandmothers, with regards to their relationships while exchanging the specific type of intergenerational support. The data for this study came from 42 in-depth, individual interviews with 21 pairs of employed mothers who had at least one child younger than elementary-school age and their mothers or mothers-in-law who had provided child care on a daily basis for their grandchildren. Our phenomenological analysis revealed that the grandmothers felt uncomfortable and overwhelmed when caring for their grandchildren and that they considered this activity to be different from caring for their own children by nature. However, the grandmothers wanted to help their adult children based on their feeling of "boo-mo-ma-eum" (meaning parental heart, i.e., love or care). The employed mothers perceived that they were substantially dependent on the grandmothers by receiving help with child care and housework. Reliance on grandmothers was inevitable and beneficial to these mothers. Dynamic intergenerational living arrangements enabled the dependent relationships. The grandmothers set specific boundaries pertaining to current and future child care so that they would not take on too much responsibility for child care. The mothers used various strategies that contributed to stable child care support from the grandmothers. Providing financial remuneration was an important strategy that had symbolic relational meanings, such as expressing gratitude, rather than financial meanings.

Ousters have become a key focus of interest and analysis over the last decade or so, informed by the work of the Harvard business economist Michael Porter. Recent research, however, suggests that the classic Porterian conception of clusters needs to be rethought. In particular, the idea that clusters are geogaphically bounded and integrated units whose primary link to the outside world is through the export of goods and services to global markets is highly Questionable, if not untenable. Relational approaches to clusters and regional development stress the importance of the wider networks and 'pipelines' through which knowledge is exchanged with key partners and collaborators located outside of the particular cluster in question. Rather than the main external links being those between leading firms and global markets, firms may engage in a range of global relations with collaborators and suppliers. This paper address the challenge of rethinking clusters in the light of the recent emphasis on global networks md connections, drawing on experience from m old industrial region in Western Europe Scotland. In assessing cluster experiences and initiatives in Scotland, I examine the development of the oil and gas and electronics clusters. In conclusion, I suggest that cluster initiatives me only likely to generate lasting benefits for the region in question if there is significant local ownership md control of key industries and clusters.

Background : Tinnitus is common disorder with many possible causes and a symptom of many different diseases but has no effective treatment. Approximately 20% of tinnitus patients experience the disorder to a degree that their quality of life and productivity are impaired. Objectives : 1. Through symptoms of tinnitus, we tried to find out the relationship of Heo-sil(虛實) and Jang bu byun jeung(臟腑辨證). 2. By testing THI, we tried to evaluate the quality of life between high-grade tiny noise and low-grade roar tinnitus patients group. Methods : 34 patients were recruited in this study who was ill with tinnitus. They wrote out the questionnaire about tinnitus and the tinnitus Handicap Inventory(THI). Results : 1. The vast majority of high-grade tiny noise patients are Heojeung(虛症). 2. The vast majority of low-grade roar patients are Siljeung(實症). 3. The number of patients with intermittent and persistent tinnitus is similar. 4. In high-grade tiny noise, Sin jung hyu son type(腎精虧損型) patients are less comfortable with quality of life than Bi wi heo yak type(脾胃虛弱型) patients. 5. Low-grade roar patients are less comfortable with quality of life than high-grade tiny noise atients Conclusions : Jang bu byun jeung(臟腑辨證) and Distinguishing between Heo(虛) and Sil(實) is expected to have positive effects on tinnitus treatment.

Fraction is one of the concepts which are difficult to elementary school students. So, many researches about fraction were performed in mathematics education research. In special, fraction has so many subordinative concepts-proper fraction, improper fraction, mixed number. We have to concentrate on the conceptual understanding in teaching of fraction. In this case, a mixed number and improper fraction are concepts which can convert respectively. And there are methods that a mixed number and improper fraction can be converted. So, it's needed to analyze the converting methods in textbooks for getting the implication of teaching in this areas. In this study, I analyzed the Korean and foreign's textbooks. I certified the methods-using addition expression, using part-whole model in the textbooks. For the conceptual understanding, I suggested to use the fusion of the various part-whole fraction models and addition expression more than the algorithm in converting between a mixed number and improper fraction. It's reason that the use of models in converting between a mixed number and improper fraction is important for the relational understanding.

Generally, real system that is the object of decision-making is very variable and sometimes it lies situations with uncertainty. To solve these problem, it has used statistical methods as significance level, certainty factor, sensitivity analysis and so on. In this paper, we propose a method for fuzzy decision-making based on MFAC(Multiple Fuzzy Alpha Cut) to improve the definiteness of classification results with similarity evaluation. In the proposed method, MFAC is used for extracting multiple a ${\alpha}$-level with proximity degree at proximity relation between relative Hamming distance and max-min method and for minimizing the number of data which are associated with the partition intervals extracted by MFAC. To determine final alternative of decision-making, we compute the weighted value between extracted data by MFAC From the experimental results, we can see the fact that the proposed method is simpler and more definite than classification performance of the conventional methods and determines an alternative efficiently for decision-maker by testing significance of sample data through statistical method.
