The aim of the study was to quantify and explore the causal relationships of appearance management through an analysis of one's own clothing and wearing experience, namely clothing preference, personality factors, emotion and mood, newness, familiarity of one's own clothing, and social interaction. Explorative quantitative and qualitative research was carried out using a uniformly composed sample of 10 size 12 females. A personality questionnaire was completed a short while prior to the study. A 10 day ‘wearing diary’ was administered to record where and when outfits were worn. Two questionnaires were completed measure emotion and mood, prior to changing into clothing (a daily baseline), and when they were wearing or changed clothing (dynamic mood). Qualitative information was recorded and included their thoughts and feelings other than the questionnaires, along with photographs that were taken by participants. Preference, social and newness ratings for each outfit worn were recorded after the 10 day period. SPSS analysis identified relationships and linear regression analysis identified preference indicators. Thematic analysis identified 9 themes regarding the management of mood, personality and social factors when wearing one's own clothing. The results indicated strong relationships between emotion, mood, personality and preference and how much newness and different levels of social interaction influence these factors. Participants tended to match their mood and personality with their clothing choices but in some cases also compensated. This research recognises the value of consumer psychological processes involved in appearance management, and has implications for further research into product involvement, post-purchase behaviour and retail strategies for personal shoppers.

Purpose: The purpose of this study is to understand a variety of intervention studies to prevent smoking by adolescents in U.S. and find out implications for Korea. Methods: This study reviewed articles found in the internet and analysed the data of US DHHS and CDC. Results: The School Health Policies and Programs Study (SHPPS) is a national survey periodically conducted to assess school health policies and programs of U.S. The main components of SHPPS are health education and physical education, health services, mental health and social services, school policies, and school environments. The CDC guidelines for school health programs to prevent tobacco use and addiction are composed of policy, instruction, curriculum, training, family involvement, tobacco-use cessation efforts, and evaluation. School-based interventions to prevent smoking can be classified into the categories of information-giving curricula, social competence curricula, social influence approaches, combined methods draw on social competence and social influence approaches and multi-modal programmes and Youth Empowerment study. The key programs for adolescent smoking prevention are ALERT Project, HSPP, TNT Project, MPP, NC YES. Conclusions: As smoking is often the first step of unhealthy behaviour such as alcohol drinking, illegal drugs, and violence, smoking prevention programmes for adolescents in U.S. have been comprehensive school-based health programs. In smoking prevention programs for adolescents, CDC plays a critical role by supporting survey, research, policy, and funds. The effectiveness of the programs was high when it was based on school and involved parents, community, and mass media. As the effect of each programme is not expected to last for a long time, consistent repetition of these interventions is essential. Current smoking prevention programs for adolescents are exploring the empowerment approach focused on the active involvement of participants rather than traditional approaches using order and discipline.

The accurate and quantitative ground information on the hydraulic conductivity characteristics of rock mass is one of the key factors for evaluation of the hydro-geological behaviour of rock mass around an excavated opening under high water pressure. For tunnel and rock structures in seabed, where the sea acts as an infinite source of water, its importance become greater with increasing construction depth below sea level. In this study, to improve the problems related with poor system configuration and incorrect data acquisition of previous hydraulic packer testing equipment, we newly developed an integrated main frame and 30 bar level waterproof downhole sonde apparatus, which were optimized for deep hydraulic packer test in seabed rock mass. Integration of individual test equipment into one frame allows safe and efficient field testing work on a narrow offshore drilling platform. For the integrated type main frame, it is possible to make precise stepwise control of downhole net injection pressure at intervals of $2.0kg_f/cm^2$ or less with dual hydraulic oil volume controller. To ensure the system performance and the operational stability of the prototype mainframe and downhole sonde apparatus, the field feasibility tests were completed in two research boreholes, and using the developed apparatus, the REV(Representative Elementary Volume) scale deep hydraulic packer tests were successfully carried out at a borehole located in the basalt region, Jeju. In this paper, the characteristics of the new testing apparatus are briefly introduced and also some results from the laboratory and in-situ performance tests are shown.

In Korea, the methods of estimating groundwater recharge can categorized into two groups. One is baseflow separation method by means of groundurater recession curve, the other is water level fluctuation method by using the data from groundwater monitoring wells. Baseflow separation method is based on annual recharge and lumped concept, and water-table fluctuation method is largely dependent on monitoring wells rather than water budget in watershed. However, groundwater recharge rate shows the spatial-temporal variability due to climatic condition, land use and hydrogeological heterogeneity, these methods have various limits to deal with these characteristics. For this purpose, the method of estimating daily recharge rate with spatial variability based on distributed rainfall-runoff model is suggested in this study. Instead of representative recharge rate of large watershed, the subdivided recharge rate with heterogeneous characteristics can be computed in daily base. The estimated daily recharge rate is an advanced quantity reflecting the heterogeneity of hydrogeology, climatic condition, land use as well as physical behaviour of water in soil layers. Therefore, the newly suggested method could be expected to enhance existing methods.

This study would be research for correlations between ethical factors and company's competitiveness of small and medium enterprises thorough recognizing of important company ethic and approaching to them theoretically. This study has collected all information which small and medium enterprises around Seoul and Kyounggi province and employing more than 5, which 134- survey are used totally. Study reveals that firstly customer and social responsibility provide Positive effects on the organization Dust, secondly CEO's views serve those positive effects as well, thirdly it is not preyed that ethical capacity of company have a positive effect on organization trust. Fourthly, organization trust has good effects on competitiveness of product and price. This results lead to some suggestions as follows. First of all, company should serves systemized value to customers and their societies. For that, it is necessary to analyse their needs and to reflect them into corporate management to build close relationship with customers and reliable marketing activities, efforts to enhance corporate images. This chain of work can make employees feel proud themselves. Secondly, supervisors including CEO should set the pace with high-consensus for ethical behaviour. Thirdly, ethical factors should be improved for improving organization trust simultaneously. Every customer, no matter they are inner or outer, should have highly required ethical understandings for their networks. Furthermore, they have to enhance organization trust and to strengthen company competitiveness through stimulating employee's courages and contribution.

Ground reaction curve is very useful information for estimating the installation time of the tunnel support. The ground reaction curve can be estimated by analytical closed form solutions derived in case of circular section and isotropic stress condition. The nature of the ground reaction, however, depends significantly on tunnel configurations. Nevertheless, few purely analytical and experimental studies of this problem due to tunnel configurations appear to have been carried out. Therefore, it is necessary to investigate the influence of tunnel configurations in order to use simply in practical design. This paper describes a numerical study for the intial elastic displacement in the ground reaction curve due to configuration of tunnel excavation. In order to evaluate the applicability of analytical closed form solution in practical design, the parametric studies were carried out by numerical analysis in elastic tunnel behaviour. In the studies, S value, namely configuration factor, defined as the ratio between tunnel height (b) and width (a), varies between 0.5 and 3.0, initial ground vertical stress varies between 5~30 MPa for each S values. The results indicated that the self-supportability of ground is larger in the ground having low S value. It, however, is suggested that the applicability of closed form solution may not be adequate to determine directly the installation time of the support and self-supportability of ground. It should be necessary to perform the additional numerical analysis.

This paper presents the development of simulation system on EPB shield TBM Hood operation. In recent, EPB shield TBM is widely used in the tunnel construction. Since the hood system of the EPB shield TBM is most important to excavate the tunnel, it is necessary to perform the simulation of hood system to investigate the design and operation parameters prior to tunnel construction. In order to carry out this study, the scaled simulation system was designed and developed. The model tests were performed to verify the developed system. During the simulation, the earth pressures developed in the chamber during tunnelling were measured to evaluate the operation technique. The test results obtained by the developed simulation system show clearly the similar behaviour of TBM hood compared with the field data. It was also found that the ground loss during tunnelling is dependent on the change of earth pressure in chamber. Therefore, the simulation system developed in this study will be very useful to evaluate the operation technique of the TBM hood prior to tunnel construction. In addition, this system will be applied in a various condition of ground to get the operating information.

This research analyzes the media which is simultaneously used with TV viewing, the behaviour of multiple media users, and the characteristics of TV programs under Nscreen circumstances. According to the results, TV provides stories and positions it as the main screen (84.5%, n=566), under the Nscreen circumstances. Personal media reproduces stories from TV by utilizing aspects of social media functions such as participation, open communication, community, connectivity, etc. The content is classified under three categories: 1) elicit emotion(point feeling), 2) information production, 3) participation, which is further divided into three subcategories; watch, wish, and result guarantee based on the level of interactivity. This inquiry is based upon diary survey and focus group interviews emphasized the role change of TV, specifically that TV takes a key role in generating original stories with the expansion of screen and social media. Even though users were able to watch the same TV programs at the same time and same place, the different methods of viewing: smartphone, tablet PC, web based mp3 and etc., it reproduced different stories and elicited different characteristics from its TV viewers.

Background: Oral cavity cancer (OCC) is one of the most common cancers worldwide. No studies have reported on the prevalence and epidemiologic risk factors of oral premalignant lesions (OPLs) in Thailand. The purpose of this study was to investigate the prevalence of OPLs and associated factors in Roi Et Province, Thailand. Materials and Methods: To investigate the prevalence of OPLs, a cross-sectional descriptive study was conducted in which 2,300 subjects over 40 years of age were recruited and screened for the prevalence of OPLs. To identify factors associated with OPLs, a matched case-control study was used in which the subjects were 102 cases with OPL and 102 matched controls without OPLs. The studies were conducted in Roi Et Province during the period 1 February, 2014, to 30 April, 2014, and the data were collected by the use of a structured interview questionnaire and by extraction of information from medical records. Data analyses involved the use of descriptive statistics, McNemar's test, and conditional logistic regression. Results: The overall prevalence of OPLs was 3.8%, and no-one was diagnosed with more than one type of OPL. The factors found to be associated with a statistically significant higher risk of an OPL were betel nut chewing, smoking, and alcohol consumption. The associations with these factors were strong, especially for betel nut chewing and smoking. Conclusions: The habits of betel nut chewing, smoking, and alcohol use are confirmed as factors associated with OPLs in a population of Roi Et Province, Thailand. Campaigns to reduce such risk healthy behaviour are needed, but whether any actual decrease will prevent the eventual transformation of an OPL into an OCC remains an open question.

A hospital-based case-control study was carried out to investigate the risk factors of uterine cervical cancer in Korea. Information on a wide-range of life-styles, which might be related with uterine cervix cancer, has been routinely collected through a dual application of the self-administered questionnaire and the direct interview by a well-trained nurse at the Department of Gynecology, Seoul National University Hosiptal since 1992. The number of cervical cancer cases, histologically confirmed at the hospital, were 284. Included were 939 women as controls, who were free of past history of any malignancies. Adjusted odds ratio and 95% confidence limits were based on the unconditional logistic regression model. The multivariate logistic model was constructed under the consideration of biologic characteristics on the natural history of the malignancy. In the multivariate results, the uterine cervical cancer risk was higher in women of shorter height$(P_{trend}<0.05)$, less educated spouse$(P_{trend}<0.001)$(0.001), multiple marriages(adjusted OR=2,70, 95% C.I. $1.64\sim4.47$), ever had a family history (adjusted OR=2.14., 95% C.I. $1.18\sim3.89$), multiparity$(P_{trend}<0.001)$, and early age at first $(P_{trend}<0.001)$. These results strongly suggest that the uterine cervix cancer might be related to the reproductive factors, and probably with sexual behaviour of both women and men in Korea.
