The biologic potential, which is different from the piezoelectric signals, relates tooth movement at least in part to changes in bone metaboliosm in bioelectric theory. The purpose of this experiment was to determine wheather the application of half sine-wave pulsed electromagnetic fields (HSPEMF) could increase both the rate and amount of orthodontic tooth movement. Forty-three male Hartley guinea pigs, weighting approximately 255g, were utilized in this study. The animals were 35 days old at the start of the study. Laterally directed orthodontic force was applied to the maxillary central incisors of 40 Hartley guinea pigs (20 experimental, 20 control). According to the amount of orthodontic force (6g, 12g), they were divided into two sub-groups (10 experimental I, 10 experimental II, 10 control I, 10 control II). During the experimental period, experimental animals were placed in plastic animal holders with their heads positioned in an area of uniform electromagnetic field. Control animals were placed in similar plastic holders that did not carry the electric apparatus. The results were as follows : 1. The application of a HSPEMF to the experimental groups significantly increase the final amount of orthodontic tooth movement observed over a 10-day experimental period. 2. The application of a HSPEMF to the experimental groups significantly increase the velocity of orthodontic tooth movement observed over a 10-day experimental period. 3. There was no significant difference in the final amount of orthodontic tooth movement at the fourth day to the eighth day, but there was significant difference in the final amount of orthodontic tooth movement at the nineth, tenth day during a 10-day experimental period. 4. After 10 days of HSPEMF exposure & orthodontic force, the experimental groups demonstrated more osteodasts in the pressure side than control groups.

This study deals with a counseling case in which a mother requested counseling due to the problems of her daughter, who suffers from multiple tic disorder. The participants of this study included five family members (grandmother, father, mother and two female children) and a total of 23 sessions were held from September 2006 to December 2007. Additional counseling ($24^{th}$ counseling session) was conducted on April 1st, 2009. The data was based on recorded transcripts and notes from 24 family therapy sessions. The study used a constant comparative analysis, which uses matrix and network display as an analysis method suggested by Miles&Huberman(1994). The characteristics of the family of origin and the indifference of the husband had caused the wife stress. The couple had frequent conflicts due to dysfunctional communication methods, a clash of values, sexual dissatisfaction, and a lack of communication. This marital conflict became the primary factor of the daughter's multiple tic disorder. Intervention of the family therapist resulted in the setting of treatment goals based on MRI's communication theory and Bowen's family systems theory in order to solve the problem of the daughter's multiple tic disorder. Also, the therapist's intervention techniques included exploring experiences with the family of origin, shedding light on the multigenerational transmission process, exploring dysfunctional attempts at solutions, the therapist's self-disclosure, providing similar cases, dealing with resistance, and suggesting a new communication method. To solve the problem, the therapist helped the family separate the daughter spatially from her parents. Therefore, the therapist's intervention helped reduce the daughter's tics and improve relationships among the family.

The purposes of this study were: 1) to show the item difficulty hierarchy of walking/moving construct of the International Classification of Functioning, Disability and Health-Activity Measure (ICF-AM), 2) to evaluate the item-level psychometrics for model fit, 3) to describe the relevant physical activity defined by level of activity intensity expressed as Metabolic Equivalent of Tasks (MET), and 4) to explore what extent the empirical activity hierarchy of the ICF-AM is linked to the conceptual model based on the level of energy expenditure described as MET. One hundred and eight participants with lower extremity impairments were examined for the present study. A newly created activity measure, the ICF-AM using an item response theory (IRT) model and computer adaptive testing (CAT) method, has a construct on walking/moving construct. Based on the ICF category of walking and moving, the instrument comprised items corresponding to: walking short distances, walking long distances, walking on different surfaces, walking around objects, climbing, and running. The item difficulty hierarchy was created using Winstep software for 20 items. The Rasch analyses (1-parameter IRT model) were performed on participants with lower extremity injuries who completed the paper and pencil version of walking/moving construct of the ICF-AM. The classification of physical activity can also be performed by the use of METs that is often preferred to determine the level of physical activity. The empirical item hierarchy of walking, climbing, running activities of the ICF-AM instrument was similar to the conceptual activity hierarchy based on the METs. The empirically derived item difficulty hierarchy of the ICF-AM may be useful in developing MET-based activity measure questionnaires. In addition to convenience of applying items to questionnaires, implications of the finding could lead to the use of CAT method without sacrificing the objectivity of physiologic measures.

Gilles Deleuze highly evaluated Baroque as the expression body that implements the fold theory, a philosophical thinking about the nature of beings. This can be seen as a meaning that Baroque implements the essence of the world, or the power constituting that essence. In addition, the beauty of Baroque focuses on 'New Harmony' the sum of partial forms caused by each element, and not Platonic harmony. he evaluated the aesthetic of Baroque costume as 'acquisition of liberation and autonomy', 'derived force from infinite spiritual forces'. This study analyzed the contents of the Aesthetic of Baroque costume based on the reviewed Deleuze's folding theory, Baroque aesthetics, and views of Baroque costume. As a result, it inferred the aesthetic of Baroque costume into four types, which are as follows: open structural openness, overlapping structural dynamics, integrated structural diversity, and relationship structural integrity. This study analyzed the aesthetic of Baroque costume based on Deleuze's philosophical thinking. The analysis showed that its aesthetics, which focused on "New Harmony", created energy of life and a venue for expression of power, as the aesthetics eliminated the prejudice of complexity and excessive decoration. In addition, Baroque costume is not the simple historical costume of the past. Instead, it is one of power and spirit, still existing in modern fashion. Baroque costume's formativeness and Paradigm can be said to provide the creative principle important for modern fashion because the aesthetics implemented in Baroque costume accepts free spirit, new challenge, difference and diversity, and is similar to the spirit pursued by modern art and fashion.

The traditional masculinity has been gradually diversified towards the 21th century due to a new social environment. Men embrace his feminine side with heightened aesthetic sense using cosmetic products for better skin, hair, and nails. This diversification of male image and his beauty style proves the addition of feminity to masculinity. C. G. Jung felt that we are all really bisexual in nature. The anima is the female aspect present in the collective unconscious of men and it is the archetype through which we communicate with the collective unconscious generally, and it is important to get into touch with it for self-realization. This study analyzes subconscious desire based on the anima archetype in the collective unconscious of men through the diversity of the gender identity shown in men's cosmetic advertisements, and therefore it aim to help developing a marketing strategy of male beauty industry in the future. For this purpose, it conducted an empirical analysis of male beauty style in cosmetic advertisements through the Jungian anima theory. The conclusion of this study is as follows: First, gender identity represented in cosmetic advertisements was typified as Retrosexual, Ubersexual, Metrosexual, Cross sexual. Second, the anima archetype stimulates feminity in male beauty style. Cross sexual type has the highest feminine tendency. Third, range of utilization of cosmetic products is articulated with the diverse gender identity. Cross sexual type is most similar to the female beauty style. This feminization of male beauty style is the external expression of collective unconscious and affords human being to reach self-realization.

In this research, we conducted an empirical study using the theory of sociologist Jean Baudrillard to examine the phenomenon of contemporary people in Korea acquiring tattoos. The researcher classified the consumption behavior of modern society, as described by Baudrillard in The Consumer Society, into three keyword phrases: consumption by personal taste, coded consumption, and recyclage of consumption. Using this as the premise of the study, 18 men and women in their 20s and 30s completed questionnaires and interviews, and the results supported labeling tattoo consumption as consumption by personal taste, tattoos as coded consumption, and recyclage of tattoo consumption, similar to the consumption pattern that Baudrillard sees. First, the younger generations have consumed tattoos according to their personal preferences. They express themselves by tattooing for self-complacency, self-marking, pursuing individuality, overcoming the appearance complex, and seeking pleasure. Second, they have consumed socially coded tattoos. They say that tattoos domestically act as negative codes and symbolize individuals. Although tattoos are a symbol of artists who are relatively free from social norms, they are still a symbol of social misfits created as such by negative perceptions. Third, the pattern of tattoo consumption is like that of contemporary consumption. Tattoos already have become part of popular culture in Korea, and there has been a changing trend in tattoo culture. This study has significance in that tattoos were regarded as a consumption behavior that deviated, from the perspective of deviance. That phenomenon of today's tattoo culture of today was confirmed through the empirical study.

The aim of affective engineering is to develop a new product by translating customer affections into design factors. Affective data have so far been analyzed using a multivariate statistical analysis, but the affective data do not always have linear features assumed under normal distribution. Rough sets model is an effective method for knowledge discovery under uncertainty, imprecision and fuzziness. Rough sets model is to deal with any type of data regardless of their linearity characteristics. Therefore, this study utilizes rough sets model to extract affective knowledge from affective data. Four types of scent alternatives and four types of sounds were designed and the experiment was performed to look into affective differences in subject's preference on air conditioner. Finally, the purpose of this study also is to extract knowledge from affective data using rough sets model and to figure out the relationships between rough sets based affective engineering method and statistical one. The result of a case study shows that the proposed approach can effectively extract affective knowledge from affective data and is able to discover the relationships between customer affections and design factors. This study also shows similar results between rough sets model and statistical method, but it can be made more valuable by comparing fuzzy theory, neural network and multivariate statistical methods.

The counter-diffusion of aromatic compounds such as coronene and tetra-phenylporphine by injection of acetone or tetra-phenylporphine solution was studied on aluminas and silica-alumina used widely as catalysts support. The counter-diffusivity was determined from simulation results by using the counter-diffusion model employing ideal adsorbed solution theory. The counter-diffusivities of aromatic compounds in the catalyst supports were ranged in ${\sim}10^{-15}m^2/sec$ in the desorption process by the injection of excess acetone. In the counter-diffusion process with tetra-phenylporphine solution which have similar concentration with adsorption solution, the counter-diffusivities of coronene were also ${\sim}10^{-15}m^2/sec$, and that of tetra-phenylporphine into pores were determined as ${\sim}10^{-11}m^2/sec$. The counter-diffusivities of coronene desobed from the adsorbent were significantly redyced in comparison with the effective diffusivities when there is counter-diffusion flux. The values mainly depended on the existence of counter-diffusion flux, but not concerned with the species and amount of desorbates.

Many Studies of tunnel and tunnelling safety have been developed continuously based on the increasing social interests in underground space since 1990's in Korea. Because the growth of population in metropolitan has been accelerated at a faster pace than the development of the cities, underground facilities have been created as a great extent in view of less land space available. In this study, a lot of types of tunnel failure were surveyed and the detail causes were studied after many cases of tunnel failure were collected. There were suggested brief countermeasure of tunnel failure through case study. An expert system was developed to predict the safety of tunnel and choose proper tunnel reinforcement system using fuzzy quantification theory and fuzzy inference rule based on tunnel information database. The comparison result between the predicted reinforcement system level and measured ones was very similar. In-situ data were obtained in three tunnel sites including subway tunnel under Han river. This system will be very helpful to make the most of in-situ data and suggest proper applicability of tunnel reinforcement system developing more resonable tunnel support method from dependance of some experienced experts for the absent of guide.
