study analyzed the relationship between ChildCare Teachers' Office Stress on Happiness with Teacher Effectiveness. A survey was conducted on 243 childcare teachers in J area. The collected data was analyzed using the JAMOVI program to analyze the mediated effects and technical statistics. Results found that office stress, teacher efficacy, and sense of happiness of childcare teachers were found to meet the normality assumption. Second, the analysis of the relationship between office stress, teacher efficacy, and happiness showed a statistically significant negative correlation between administrative stress and teacher efficacy and happiness and teacher efficacy showed a significant positive correlation. Higher office stress led to less teacher effectiveness and happiness, and higher happiness led to higher teacher effectiveness. Third, office stress is a significant predictor of happiness and teacher's efficacy. In conclusion, office stress should be considered important in terms of happiness and teacher effectiveness and the direction of improvement in the treatment of child care teachers was suggested.

In the Part I, the three dimensional model testing with NNW deep water wave direction gave the results such that the occurrence of breaking waves over the peak of Ear-Do caused very small wave height at the structure position. But the measured wave forces were rather greater than the calculated forces based on deep water wave height. Furthermore, It was also perceived that the time series of the forces looked like corresponding to the case that waves were superimposed by an unidirectional current. In the present Part II, the current is presumed to be a flow secondly induced by breaking waves, and an extensive study to clarify the current in a quantitative sense is performed through numerical analysis and hydraulic experiment. The results showed that a strong circulation can surely occur in the vicinity of the structure due to radiation stress differentials given by the breaking waves. It was also recognized that the velocity of the induced current varied with the magnitude of energy dissipation rate introduced in the numerical analysis. The numerical analysis was tuned adjusting the dissipation rate so that the calculated wave field could closely match with the experimental results of Part I. The fluid force (in prototype) for the optimal match showed approximately 2.2% increased over the calculated value based on the deep water wave height (24.6m) whereas the force corresponding to the average of the experimental values showed the increase of about 13.0%.

This study aims at surveying how Koreans look upon and prepare for the age of longevity("age of 100 years") drawing near at hand, analyzing factors affecting such a perception and behavior. To this end, a telephone survey was launched for 1200 persons sampled to evenly comprise the young, middle-aged, and elderly groups. Our findings indicate that more Koreans looked upon the upcoming "age of 100 years" as a 'disaster' rather than a 'blessing.' The sense of combined uneasiness over the aged life being further elongated while they are unprepared for it, anxiety over maintaining health and so forth came into play. However, the better a person is prepared by way of health management, savings for retirement, preparation for leisure activities and employment for the later life, the more positively he or she looked upon the "age of 100 years". An analysis by group indicates that women rather than men, the elderly rather than the young, the less educated rather than the highly educated, the low-income bracket rather than the high-income bracket looked upon the "age of 100 years" more negatively. Under such circumstances, it is suggested that the nation's social system tailored to a life expectancy of 80 years should be readjusted, tailored to a 'longevity paradigm' and that to this end social systems should be reoriented toward the direction where 'healthy aging' and 'active aging' are fully supported.

Modernization drastically changed the cosmetic culture of Korea and Japan. A classic case that shows this is the appearance of the term 'Hyangjang (香粧)'. This paper investigated the background to the formation of the term Hyangjang (香粧), and reviewed the aspects of cosmetic culture that changed with the emergence of Hyangjangpum (香粧品), or cosmetics containing perfume. The investigation revealed that the term Hyangjang (香粧) appeared for the first time in Hirano (1899), a literature published in the Meiji period in Japan, and that the new term Hyangjang (香粧) had been formed against the background of advanced Western synthetic perfume and played an important role in contemporary techniques for the manufacture of cosmetics. The term Hyangjang (香粧) and cosmetics containing perfume, or Hyangjangpum (香粧品) were then introduced from Japan to Korea. In Korea, the term 'Hyangjang (香粧)' appeared for the first time in an advertising copy written by Hyeon Hui-un, a pioneer of the Korean modern theater movement during the period of Japanese colonial rule. At that time, cosmetic companies in Korea and Japan were releasing cosmetic products that contained perfume that stimulated a women's desire to purchase them by emphasizing 'fragrance' in their advertising. Existing public tendencies to regard a fragrant smell from a made-up face as vulgar were changing and the public perception of fragrance were also changing. The appearance of Hyangjangpum (香粧品) indicates that the existing cosmetic culture revolving around visual sense changed into a complex cosmetic culture involving olfaction. This change in culture is significant in that it heralded the direction of future development towards cosmetic culture that uses increase combinations of different senses including touch, taste, and hearing.

This paper proposes an iterative high-resolution image interpolation algorithm using spatially adaptive constraints and regularization functional. The proposed algorithm adapts adaptive constraints according to the direction of..edges in an image, and can restore high-resolution image by optimizing regularization functional at each iteration, which is suitable for edge directional regularization. The proposed algorithm outperforms the conventional adaptive interpolation methods as well as non-adaptive ones, which not only can restore high frequency components, but also effectively reduce undesirable effects such as noise. Finally, in order to evaluate the performance of the proposed algorithm, various experiments are performed so that the proposed algorithm can provide good results in the sense of subjective and objective views.

The purpose of this paper is to analyse the essence of proportional reasoning and to analyse the contents of the textbooks according to the mathematics curriculum revised in 2007, and to seek the direction for developing the proportional reasoning in the elementary school mathematics focused the task variables. As a result of analysis, it is found out that proportional reasoning is one form of qualitative and quantitative reasoning which is related to ratio, rate, proportion and involves a sense of covariation, multiple comparison. Mathematics textbooks according to the mathematics curriculum revised in 2007 are mainly examined by the characteristics of the proportional reasoning. It is found out that some tasks related the proportional reasoning were decreased and deleted and were numerically and algorithmically approached. It should be recognized that mechanical methods, such as the cross-product algorithm, for solving proportions do not develop proportional reasoning and should be required to provide tasks in a wide range of context including visual models.

Sensor networks are needed for special purposes such as collecting or transmitting information by using sensor devices, for which various routing protocols have been proposed. Among existing protocols, the modified PEGASIS routing technique is known to be effective when applied to cases with directional transmissions of data. However it does not consider recovery from errors or guaranteeing stability in data transmission, while sensor devices performing repetitive relays and controls are prone to errors. In this paper, a double relay routing protocol for Zigbee based sensor networks where data are transfered reliably with a linear direction. The proposed protocol is effective in the sense that it secures the relaible transmission of data with minimal energy consumption based on a directional data transfer. A streetlight control system has been presented as an application of the proposed protocol.

The purpose of this study is to provide further direction to the culture program at the healthy family center by analyzinge its different concepts of family living culture, which is based on changes in the family values of an individual. This research was conducted on residents in the area of Seoul and Kung-gi from March 1, 2007 to March 30, 2007. The survey was distributed to 300 people, and 186 surveys were collected. Among those 186 surveyed, 179 were finally analyzed. Findings from the survey are as follows: First, age, gender, and marital status show differences in familism, consciousness of men's and women's equality, and recognition of family cultural ritual. As to planning the healthy family culture program, the program participants' age, gender, and marital status should be considered to successfully plan and operate the program. Second, regarding the view of family life from three aspects including the degree of recognition of family cultural ritual, familism, and the consciousness of men's and women's equality, all three variables show differences in the view of family life. Therefore, it will be highly effective to organize two separate groups: one presents lower recognition of family cultural ritual and family-based values, and another possesses a higher sense of equality. Third, the result of reviewing relative effectiveness to the proper family life value, wedding, consciousness of parents respect(=filial piety), and sacrificial rituals, funeral rites were founded to highly effective to family living view. Therefore, it will be highly effective to include these topics, when the family cultural living program is planned.

With regard to the culture in cities this study aims to essential understanding and systematic approach to the culture. The "2011 Seoul Survey"report has been used to find out causality among the related variables. In the first place 'satisfaction of cultural condition' was operationally selected as a dependent variable for regression. For the purpose of controlling confounding factors for ceteris paribus effect correlation analysis was done between the dependent variable and all other variables respectively, which resulted in two groups of variables: group (1) - 6 variables of very significant correlations(p-value<0.01) and (2) - the other 6 variables of significant correlations(p-value<0.05). Then hierarchical regression was adopted to these 2 groups to analyse $R^2$ increment, statistical significance of independent variables, and multicollinearity(VIF; variance inflation factor). At last a regression model specified by group (1) as independent variables(they are 'social trust', 'satisfaction of walking condition', 'happiness index', 'preparation against old age', 'satisfaction of traffic condition' and 'hours for internet') shows that only 'social trust' variable has statistically significant and substantially strong effect on 'satisfaction of cultural condition.' This finding should be accepted on the following understanding; (1) urban culture has a collective attribute formed between people and society, (2) culture is somewhat telling and hearing stories and the confidence between tellers and hearers is essential in the mutual response and (3) stimulus is received by relationship in company with sense, emotion, thinking and action. In spite of restrictive external validity this finding can be used as a direction for promoting culture and a basis for related policy choice in cities.

Objectives The aim of this study is to analyze the therapeutic direction and characteristics of gastrointestinal diseases by three societies of Korean medicine by comparing the frequent disease patterns and prescriptions of them. Methods The experts of the three societies of Sasang constitutional medicine, Hyungsang medicine and Sanghan-GeumGwe medicine discussed and confirmed a list of clinical data to make use for diagnosis. Then, clinical data on 200 patients suffering from gastrointestinal symptoms were collected. The each experts diagnosed appropriate disease patterns and decided prescriptions according to the method of their affiliated society. Results and Conclusions The three different societies' experts showed the similarity in the sense of categorizing disease patterns focusing on the specific physiology and pathology of the patients, while the each societies have different diagnosis systems. Treating chronic gastrointestinal patients, they treated the mental or psychological symptoms of the patients as well as their physical problems. Based on this study, it is necessary to develop a systematic and precise research model to objectively and statistically analyze the correlation of disease patterns and prescriptions by different societies.
