Supply of a smart device has been made with the development of communication networks and growing desire of people to improve the quality of life, the service industry about it have been made with smart devices. Among them, there are various services that can help people change their behavior to healthy life. But it does not have a large impact on the behavior change of performer because its been developed as a general process. Therefore in this study examine development situation about current behavior change applications through application markets. Development current situation can be separated by process to two patterns. As a result we propose behavioral change model that includes integrated change model that one of the behavior theory model, accomplish the goal process of goal setting theory and habit formation phase for automate the changes. Also, we provide appropriate service according to the model that leads motivation, sustainability of the action and positive behavior change to performer. We can expect in many aspects such as ability and motivation than existing service.

The very erosive cavitation is simulated by an inclined propeller dynamometer in the medium-size cavitation tunnel of MOERI. The inclined shaft for propeller makes strong cavitaion, which occurs around the root of a propeller blade. The cavitation begins at the leading edge of the propeller and contracted toward the trailing edge through the reentrant jet action. The cavity focused on the region near the trailing edge collapsed over the blade surface. As the impact pressure by the cavitation collapsing is too strong, it can damage the blade surface in the form of pit. This cavitation impacts created by the collapsing process are similar to the full-scale ones and are different from those by other erosion test methods. The newly developed cavitation erosion test method can be applied to evaluate the materials such as metals, ceramics and coatings in terms of cavitation resistance.

The purpose of this study was to examine generational differences between the youth and the middle-aged in attitude and voluntary behavior toward the elderly, to analyze the socio-demographic and psychological characteristics influencing attitude and behavior toward the elderly, and to find out whether the attitude of the youth and the middle-aged toward the elderly was the decisive factor in their behavior toward them. For this study, we surveyed 252 youth (between the ages of 20 and 30) and 314 middle-aged people (between the ages of 40 and 60). The major results were as follows: First, the psychological factor had a stronger influence on the positive attitude toward the elderly than did the socio-demographic factor. The psychological factor had an especially significant impact on the attitude of the middle-aged population. Second, youths' attitude toward the elderly influenced their behavior toward them; whereas, for the middle-aged, the socio-demographic characteristic was a decisive factor. Third, the youths' area of residence was an important factor in their attitude toward the elderly; the youth in the metropolitan area had a more negative attitude than did their counterpart. Therefore, it is necessary to develop programs to improve the negative attitude toward the elderly for the youth residing in the metropolitan area. The middle-aged need more easily accessible voluntary work programs by which a positive attitude toward the elderly leads to immediate action.

This study, after analyzing 2019 Cannes Lion winners, suggests five creative trends. It was found that these global five creative trends are multi-sensory experience, integration between data and creativity, real humanism, brand activist, and consideration for socially disadvantaged. Not only visual impact or stimulus, but audio or scent could be utilized in an effort to stimulate consumers and promote brands. In 2019 Cannes Lions advertising campaigns which sought to find consumer insight through data and apply it to creativity received applause from Cannes Lions judges. In addition, advertising campaigns based on real humanism suggest that attitudes are best changed through positive experiences. Nike's 'Dream Crazy' campaign is a good example which shows a company's philosophy and brand purposes. Brands are becoming activists and are being encouraged to take real action, and for good reason. Lastly, projects such as Ikea's 'ThisAbles' and Microsoft's 'Xbox Adaptive Controller' are contrived for the socially disadvantaged.

Native crystalline chitin was hydrolyzed in an agitated bead reaction system using crude chitinase excreted from Aspergillus fumigatus JC-19. The reaction was enhanced significantly, and the concentration and yield of reducing sugar after 48 hours were measured to be 35.42 g/I (w/v) and 0.64, respectively, around 1.86 times higher than those of the conventional system that was carried out without glass beads. The effect of reaction conditions, such as the amounts of chitin, chitinase and glass beads, and the size of glass bead, were examined. Ball milled chitin was also hydrolyzed in the agitated bead reaction system, the conversion yield and reaction rate of ball milled chitin for 24 hours increased up to 0.87 and 48.02 g/I, respectively. Chitinase showed relatively high stability in the agitated bead reaction system, particularly in the presence of enzyme stabilizer, $Ca^{++}$, which played a critical role in preventing the deactivation of chitinase by the physical impact of glass beads. The variations of the structural features of chitin during the reaction were followed by SEM and X-ray diffraction, and the enhanced hydrolysis reaction was caused by both the fragmentation of chitin particles and the destruction of the crystalline structure owing to the synergic effects of the attrition of glass beads and the hydrolytic action of chitinase.

CYP1A1 is known to be inducible by xenobiotic compouds such as polyciclic aromatic hydrocarbons(PAHs) and 2,3,7,8-tetrachloro-dibenzo-p-dioxin(TCDD). These chemicals have been identified worldwide and can have a significant impact on the human health and well being of human and wildlife. Given these issues, the detection and quantification of these chemicals in biological, environmental and food samples is important. We investigated the effect of dietaty flavonoid, such as CYP1A1 promoter activity, 7-ethoxyresorufin-O-deethylase(EROD) activity and CYP1A1 mRNA expression induced by benzo(k)fluoranthene(B(k)F) in MCF-7 cells. Based on the three criteria of frequency of occurrence in the environment, toxicity and potential exposure to humans, B(k)F is one of the top-listed PAHs. We found that B(k)F significantly up-regulates the level of CYP1A1 promoter activity, EROD and CYP1A1 mRNA. when cells were treated with daidzein inhibited the B(k)-induced CYP1A1 prompter activity and mRNA level at high concentration. But daidzein exhibited stimulatory effects B(k)F-induced CYP1A1 promoter activity and mRNA level at low concentration. Overall, results from these studies demonstrate flavonoids might interfere the action of B(k) with AhR system to stimulate CYP1A1 gene expression.

We found that B(k)F significantly up-regulates the level of CYP1A1 promoter activity, EROD and CYP1A1 mRNA. When cells were treated with morin alonem, it was not changed that EROD and CYP1A1 mRNA, compared to that of control. However, morin inhibited the B(k)-induced CYP1A1 prompter activity and mRNA level at high concentration. But morin exhibited stimulatory effects B(k)F-induced CYP1A1 promoter activity and mRNA level at low concentration. Overall, results from these studies demonstrate morin might interfere the action of B(k) with AhR system to stimulate CYP1A1 gene expression.

The domestic food service industry has established its industrial basis since the overseas brands were introduced and international events were held in Korea. It also has showed a prominent growth rate as consumers began to show more interests in leisure and quality of working life(QWL) At this, the employees, constituting Points of contacts with consumers of the food service industry, have emerged as a Primarily critical concern in order for the food service industry, which can affect people in various ways, to adopt our own food culture and develop its business quality. In the food service industry, as a relatively labour-intensive industry, the manpower service is considered very important. Whether the industry succeeds or not depends on the role of employees as the quality of service of employees can decide the quality of the industry itself. In spite of the importance of employees in the food service industry, not many researches have been Performed on the personnel management of the industry, as Koreans traditionally have hold a prejudiced view on the food service industry and it is only a short time since the food business began to be considered as an industry. This thesis aims at research on the factors affecting job satisfaction of the employees by dealing with the importance and characteristics of the role of employees of the food service industry and theoretical background of the job satisfaction. The presumable factors affecting the job satisfaction are divided into several groups ; characteristics of organization, working condition, human relationship, psychological factors, and its reputation in the labour market. Hypotheses and models, where those factors affect the employees, are formed. Statistical methods such as correlation analysis and multiple regression are used in order to verify those hypotheses. Alternatives to improve job satisfaction of employees are suggested based on the analysis. It is expected that there will be more active researches on employees of the food service industry, as this thesis has selected employees of the food service industry as its subjects while subjects of similar researches have been mainly hotel employees so far.
