Among artificial intelligence-based computational techniques, adaptive neuro-fuzzy inference systems (ANFIS) are particularly suitable for modelling complex systems with known input-output data sets. Such systems can be efficient in modelling non-linear, complex and ambiguous behaviour of cement-based materials undergoing single, dual or multiple damage factors of different forms (chemical, physical and structural). Due to the well-known complexity of sulfate attack on cement-based materials, the current work investigates the use of ANFIS to model the behaviour of a wide range of self-consolidating concrete (SCC) mixture designs under various high-concentration sodium sulfate exposure regimes including full immersion, wetting-drying, partial immersion, freezing-thawing, and cyclic cold-hot conditions with or without sustained flexural loading. Three ANFIS models have been developed to predict the expansion, reduction in elastic dynamic modulus, and starting time of failure of the tested SCC specimens under the various high-concentration sodium sulfate exposure regimes. A fuzzy inference system was also developed to predict the level of aggression of environmental conditions associated with very severe sodium sulfate attack based on temperature, relative humidity and degree of wetting-drying. The results show that predictions of the ANFIS and fuzzy inference systems were rational and accurate, with errors not exceeding 5%. Sensitivity analyses showed that the trends of results given by the models had good agreement with actual experimental results and with thermal, mineralogical and micro-analytical studies.

Porous self-bonded silicon carbide (SBSC) ceramics were fabricated at temperatures ranging from 1750 to $1850^{\circ}C$ using SiC, Si, C as starting materials and Al as an optional sintering additive. The effect of Al addition on the porosity and strength of the porous SBSC ceramics were investigated as functions of sintering temperature and Si:C ratio. The porosity increased with decreasing the Si:C ratio and increasing the sintering temperature. It was possible to fabricate SBSC ceramics with porosities ranging from 37% to 44% by adjusting the Si:C ratio and the sintering temperature. Addition of Al additive promoted densification and necking between SiC grains, resulting in improved strength. Typical flexural strengths of SBSC ceramics with and without Al addition were 44 MPa and 34MPa, respectively.

It is of importance to determine the zero effective stress void ratio($e_{00}$), which is the void ratio at effective stress equal to zero, and the relationships of void ratio-effective stress and of void ratio-hydraulic conductivity for characterizing non-liner finite strain consolidation behavior for ultra-soft dredged materials. The zero effective stress void ratio means a transitional status from sedimentation to self-weight consolidation of very soft soil deposits, and acts as a starting point for self-weight consolidation in the non-linear finite strain numerical analysis such as PSDDF. In this paper, a new method for determining the zero effective stress void ratio has been introduced with the aid of measuring electrical resistivity of the specimen. A correlation between the zero effective stress void ratio and the initial slurry void ratio has been proposed, which can be used in PSDDF analysis as an input parameter. Combining all of the accessible experimental data, the consolidation characteristics of a dredged soil from the Incheon area has been studied in detail.

Objectives: To investigate the drinking behavior and related factors of community residents in G city. Methods: Examination was executed with questionnaire to 1973 adults. Data were collected from October 1, 2005 to November 16, 2005. Drinking behavior involves rate of drinking, frequency of drinking, age of starting drinking, drinking amount, rate of attempts to drink moderately and reasons for reducing drinking. Related factors involves the general characteristics, the habits of health behaviors. This was analyzed with frequency, percentage, mean, standard deviation, x2-test, t-test, ANOVA and logistic regression. Results: The drinking rate of the respondents was 67.4%, that rate of male was 83.1%, while that rate of female was 52.5%. The drinking rate was higher in groups of younger aged and highly educated people than that rate of the other groups. The highest level of drinking frequency was ones or twice a week. The drinking frequency of those who drank more than three times weekly was higher in the groups of male, old aged, married people, low educated people, rural residents, farmers or fisherman or laborers and those who unemployed or who did not exercise frequently and control their body weight. These individuals also preferred salty food and meat and fish, dined out frequently, did not visit dental clinic regularly, and tend to be smokers. The mean of the age of starting drinking was 21.17 year-old, that of males was 19.94 year-old, that of females was 22.82 year-old. The mean of the age of starting drinking was lower in groups of male, young aged, unmarried, college educated, rural residents, clerks, high monthly income, healthy and no illness, and smokers than that of the other group. The average of the drinking amount was 5.77 pack, that of males was 7.41 pack, and that of females was 3.31 pack. The drinking amount is much more in groups of males, fifties, unmarried, college educated, rural residents, self-employed, healthy people, and smoker than the other. 33.4% of the respondents attempted to drink moderately. According to the reasons of trying to drink moderately, the rate of prevention illness was highest. Conclusions: The variables of influencing drinking were sex, marital status, education, smoking, monthly income, health status, and stress.

The recent experience about self-employment shows three main trends: first, its share out of the total workers has steadily increased, recording 37.6% in 2001, implying its prevalence and importance; second, its share out of male workers has caught up female workers', implying its importance to males as well as females; and finally, during the recent Economic Crisis when there was mass layoff and large scale bankruptcy, its share rapidly increased, reflecting its role of a buffer to economic fluctuation. However, there have been few studies on self-employment, mainly focusing on what makes someone choose it as an alternative to being employed. This study analyzes the determinants of the duration to terminate self-employment, by applying the proportional hazard model to the Korea Labor and Income Panel Survey(KLIPS) by the Korea Labor Institute. The KLIPS started the first wave in 1998 with the 5,000 household sample (and about 12,000 individual sample of household members aged 15 and more). In this study, the first four waves are used for analysis. The average duration of 5,357 spells of self-employment is 130 months. It shows slight difference between males(124 months) and females(138 months) while it widely ranges over industries (296 months for agriculture industry while 50 months for restaurant and hotel industry). Estimates of the proportional hazard model of the self-employment duration show that females are more likely to terminate self-employment while it is not statistically significant. The effect of age at starting self-employment on the hazard shows the inverse V-shape, which implies that, until a certain age(47 years), the hazard become higher as aging while, since then, it become lower as aging. The level of education has a positive effect on the hazard, implying that more education is related to the higher probability to be employed. The measures of economic performances, annual sales and earnings, are positively related to continuing self-employment while hardship at the start of self-employment measured by several ways has a negative effect. Training before opening business has a positive effect on keeping on self-employment and its effects are different over its providers, significantly positive for public providers while insignificant for private providers. More and further research on self-employment is urgent in the rapidly ageing society. To help workers to be self-employed, more public assistance is necessary for education, training, financing, marketing, management, and human resource management in order to make the olders consider self-employment as a good alternative rather than an inevitable one.

As an origin and a starting point of business start-up, this start-up intention is believed to be the driving force of economic growth. Being aware of the importance of the start-up intention, the study looked into cause-and-effect relationships of variables focusing on intermediate roles of start-up self-efficacy and intrinsic motivation in self-leadership and start-up intention of business founders. In order to achieve the research goal, the study conducted both a survey targeting a total of 195 business founders registered at a business incubation center and an empirical analysis on the results of the survey. According to the findings from the analysis, the study first learned that the self-leadership would have a positive effect on the start-up self-efficacy and the intrinsic motivation which eventually proved that the self-leadership is a leading variable of the start-up self-efficacy and the intrinsic motivation. Second, both the start-up self-efficacy and the intrinsic motivation were observed to be positively related to the start-up intention. That finding signified that roles of the start-up self-efficacy and the intrinsic motivation are important to increase the start-up intention. Third, intermediate effects of the start-up self-efficacy and the start-up intention were discovered from the self-leadership and the start-up intention, the main topics of the research. Hence, in order to improve the start-up intention, the importance of the start-up self-efficacy and the intrinsic motivation should be recognized and promoted as well and for this goal to be achieved, the business founders should understand the idea that the self-leadership has to come first than anything else in this case. Based on the results of the research, the study offers theoretical and practical implications.

In (Advaita) $Ved{\bar{a}}nta$ although human beings are destined to have a pessimistic starting point in life, their goal of life is to become a Perfect Being which is called 'Liberation' (mokṣa) by self-transcendence. This human goal together with several means are accepted by $Ved{\bar{a}}nta$ as solely valuable thing in the life. In this way there must be a self-recognition of his own value in the process of Liberation, through which one recognizes his own true nature i.e. ${\bar{A}}tman$. ${\bar{A}}tman$ is clearly defined to be 'Existence, Consciousness, Bliss' (Being, Illumination, Good), and this definition is made with the view of revealing that It is ultimate foundation and source of human beings ontologically, epistemologically and axiologically. However, as $Ved{\bar{a}}ntic$points of view on human goal are not without critical limitations, it may be necessary to revaluate 'the process of self-inquiry' devised to achieve human goal. Inquiry is, first of all, an accepting process of what is given in $Ved{\bar{a}}nta$ as the scenario that gives rise to most actual result, then, a performing and verifying process of that scenario in one's own experience consistently. In this process, a shift of action from worldly life to unworldly life is what is called 'self-adjustment', a removal of 'the self in excess' through knowledge of the real Self is what is called 'simplification of the self', and at the end of simplification a state of ultimate Self is 'Liberation'. Therefore, the inquiry of $Ved{\bar{a}}nta$ into human goal can be summarized as following formula; 'good action = self-adjustment' ${\rightarrow}$ 'good knowledge = simplification of the self' ${\rightarrow}$ 'Liberation = ultimate Self'.

There are few research on the social drinking experience reported by women. Thus, it is necessary to understand the increasing tendency of womens drinking experience in the sociocultural context. This study was aimed to explore and delineate the drinking experience of full-time house wives base don Strauss and Corbin's grounded theory (1998). The subjects of this study were 10 full-time middle-aged house wives who were living in Seoul region. The data were collected through several in-depth interviews and observations until the theoretical saturation was achieved. The data were analyzed using Strauss and Corbin's grounded theory method. The results of this study generated a paradigm that the drinking experience of the full-time middle-aged house wives has a core category of 'free-oneself-from' and is also connected with mingling, anguish, accessibility, reaction of other people, change, personal resources, self-expression and building relationships by drinking. All processes from the occurrence of the central phenomenon to extinction are as follows; 1) Starting the process of the drinking experience for mingling and resolving anguish, and by having an easy accessibility; 2) Perceiving the process of reaction by other people, physical change of herself. and psycho-behavioral change; 3) Experiencing the process of free-oneself from thorough drinking; 4) Acknowledging the process of the resources for free-oneself-from; 5) Selecting the process of self-expression according to the resources; 6) Building the process of the relationship with drinking as a way of self-expression. Based on this paradigm, 4 hypothesis and 4 types are generated. Thus, this study suggests that it is useful to develop nursing interventions to improve the self-esteem of the full-time middle-aged house wives and to provide them various methods of problem solving strategies. This study also proposes that there should be a strategic program for the women so that they could make a route for positive self-expression by achieving a proper relationship with drinking.
