Purpose: The purpose of this study is to explore the subjective experiences of relapse and treatment among the alcoholics. Methods: Phenomenological methodology was used for the study. Participants were seven people with inpatient alcoholics at the alcohol treatment center at K hospital in K province. Data were collected via in-depth interviews from March to September, 2012 and analyzed using Colazzi's framework. Results: Six themes and seventeen meanings were formulated for the relapse and treatment experiences of participants with alcoholism. Six themes were 'Lack of true insight', 'Lack of strength to live a life', 'Unable to overcome an urge to drink', 'Being drawn away from others', 'Falling into the powerlessness and despair', and 'Being foothold of self-growth'. Conclusion: The results from this study revealed the relapse experiences among alcoholic patients. Therefore, the findings can provide the framework and direction for developing the relapse prevention program for alcoholic patients. In addition, practitioners in the treatment center or hospital need to consider their relapse and treatment experience.

인터넷 웜은 컴퓨터 네트워크를 이용하여 자기 자신을 자동으로 복제해서 전파하는 프로그램이다. 컴퓨터간의 네트워크 연결이 증가함에 따라 인터넷 웜은 급격해 확산되었고 큰 위협으로 남아있다. 코드 레드, 님다, 슬레머 같은 인터넷 웜의 특성과 이들의 활동을 억제하는 방법을 찾기 위해서 웜이 전파되는 특성을 연구하려는 많은 시도가 있었다. 네트워크 특징들이 인터넷 웜 전파에 미치는 영향은 모델의 간단성과 유사성 때문에 주로 의학계에서 사용되는 전염병 전파 모델을 이용하여 모델링이 되었다. 이런 의학계 모델링은 널리 사용되면서 여러 개선된 모델들이 다양하게 제안되었다. 우리는 이전의 제안된 모델들의 문제점을 분석한 후 통계적 방법을 사용하여 정확도를 높이는 새로운 방법의 웜 전파 모델링을 제안한다.

Despite a current fascination with East Asian iconography such as Zen Style among contemporary designers, there is a lack of genuine cross-cultural discourse that could enable us to share essential design experiences. To bring the discussion a deeper level, traditional Japanese tea-house in its design philosophy of body-mind interplay is explored. Tea-house is a superb manifestation to reveal a holistic understanding of the world. Nondualistic realization is generally associated with the dominant tendency of traditional East Asian philosophy, namely the view that the self and environment, and that the mind and the body exist in unity. The essence of tea-house is not in its poetic style or meticulous details, but in its unmistakably monistic approach of creating inseparable form, function and meaning. Tea-house bestows dignity upon restraint, imperfection, discomfort, poverty, and even humility. This concept offers a tremendous insight since it implies that the rational and effective design solution to the greatest degree is not sufficient. Perhaps the most challenging question about tea-house is: How does our experience with human-made 'design' in the broadest sense help both our body and mind attain a full harmony of being? It is the heading which this research inquires.

Cancers are mainly sustained by a small pool of neoplastic cells, known as cancer stem cells or tumorinitiating cells. These cells possess the ability to self-renew and proliferate, and are thus able to form the tumor. In the present study cells that correspond to cancer stem cells in mammary and liver cancers in animals were identified by the expression of CD133, CD44, CK7, and OCT4 using immunochemistry. As a result, we found with CD133+ and CD44+ cancer stem cell-like phenotypes in mouse and canine hepatocellular carcinoma and canine mammary gland tumors. However, CK7+ and OCT4+ cells were not identified in animal mammary and liver cancer. CD133+ and CD44+ cells are wellknown stem cell lines and play key roles in development and metastasis in human cancer. These findings suggest that cancer stem cells are involved in animal tumorigenesis and may provide insight into mechanisms in cancer development as well as cancer diagnostics.

We performed nonlinear transmission measurements and quantum-chemical calculations on dithienothiophene(DTT)-based molecules to gain insight into the effect of acceptor and donor groups on two-photon absorption(TPA) properties. The TPA intensity showed dispersion characteristics of the single-photon absorption spectrum. When the molecules included an asymmetric donor-acceptor pair, the single- and two-photon absorption maximum wavelengths were red-shifted more than when the molecules had a symmetric donor-donor structure. We interpreted this result as indicating that the $S_2$ state plays the dominating role in the absorption process of molecules with a symmetric structure. The experimental TPA ${\delta}$ values at the absorption peak wavelength showed a dependence on the structural variations. We found the self-consistent force-field theory and Hartree-Fock Hamiltonian with single configuration interaction formalism to be valid for evaluating TPA ${\delta}$. Although the quantum-chemical calculations slightly underestimated the experimental ${\delta}$ values obtained from nonlinear trans -mission measurements, they reasonably predicted the dependence of the ${\delta}$ value on the structural variations. We confirmed the role of molecular symmetry by observing that donor-donor substituted structure gave the highest experimental and theoretical TPA ${\delta}$ values and that the donor-acceptor substituted structure showed a greater red-shift in the TPA absorption maximum wavelength. Overall, the theoretical ${\delta}$ values of DTT-based molecules were in the order of $10^{-46}\;cm^4{\cdot}s{\cdot}photon^{-1}$ and are higher than that of AF-50 by nearly two orders of magnitude.

As most modern architectures had been constructed aiming at only both self-reliance and the purity without considering the place, the contemporary architectures have been also exposed to 'the loss of the place' similarly. From recognizing these problems, studying new spatial approach and various movements to create new modern place overcoming this have been progressed. It is meant that building shouldn't exist away from a land, without meanings. It is need to create new space aggressively against varying spaces. Thus, This thesis focus on architect Jean Nouvel among the architects having the insight of space and study his architectural design philosophy through his works creating new space. The aim of this study is to review how to define the 'placeness', and the light as a mediator of place. First of all, this thesis begins with a review what is the 'placeness' as spatial analysis and how to define 'light' as a mediator of place with his books, scholarly lectures, interviews, writing and papers and then analyse how light is represented through 'the place program of light' from his selected works. As a result of it, the thesis provides the possibilities of his constant challenges about 'existence-space-essence' by deriving the characteristics of 'the place program of light' focused on what his architectural approach constructs new space all the time through a regular program even if hard to define all his works as one model.

This paper focuses on the actuation system combined with a piezoelectric transducer and an electric circuit, which leads to a new insight; the electric actuation system is equivalent to mechanical variable-stiffness actuation systems. By controlling the switch in the circuit, the electric status of the piezoelectric transducer is changed, and consequently a variable-stiffness mechanism is achieved on the electric actuator. This proposed actuator features a shift in the equilibrium point of force, while conventional electrically-induced variable-stiffness actuators feature the variation of the stiffness value. We intensively focus on the equilibrium shift in the actuation system, which has been neglected. The stiffness of the variable-stiffness actuator is periodically modulated by controlling the switch, to suppress the vibration of the system in an open-loop way. It is proved that this electric actuator is equivalent to its mechanical counterpart, and that the electrical version has some practical advantages over the mechanical one. Furthermore, another kind of electrically-induced variable-stiffness actuator, using an energy-recycling mechanism is also discussed from the viewpoint of open-loop vibration control. Extensive numerical simulations provide comprehensive assessment on both electrically-induced variable-stiffness actuators employed for open-loop vibration control.

is based on a true story of the first transgender individual. It portrays psychological changes visually during the protagonist's confusion with self-identity based on gender. This study analyzes gender identity in contemporary fashion intensively based on gender images and costumes appearing in the film . In the society lacking a fixed gender image, this study provides a timely insight into gender identities by analyzing the fashions depicted in the movie. The movie is a true story of the first transgender person working hard to determine his or her own gender identity. As a research method, the theoretical basis of genderless approach was established via literature review. The characteristics of genderless identity were determined by dividing the movie into established and ambiguous gender periods to analyze the comprehensive changes in costumes for comparison. Einer Wagner representing male identity portrays men's fashion whereas Lily Elbe representing female identity depicts women's fashion. While the two different genders find their places in a single body, the confusion creates genderless fashion. By dividing these phases into femininity, masculinity and genderless categories, each costume was analyzed comprehensively, and the images of relatively changing fashion were studied by altering the gender identity. Four characteristics including androgyne, rebellion, pleasure and balance were derived from the gender identity based on Fashion in .

Keeping good, talented people is one of the most significant factors in a company's success. HR analytics is an important area for applying big data analysis techniques to human resources. It provides organizational insight that enables effective management of employees, allowing management to reach their business goals quickly and efficiently. Job satisfaction and employee turnover analysis are the keys to HR analytics. Job review web services have been becoming popular. Because people exchange information about job satisfaction and turnover through these web services, useful information about HR Analytics is accumulated on the job review web sites. In this paper, we identified factors of employee retention by analyzing a Job Satisfaction/Retention group, and the factors of employee turnover by analyzing a Job Unsatisfaction/Turnover group. In order to do this, we first classified employees according to whether their self-reported job satisfaction or turnover was true. We collected and analyzed data from Jobplanet, a popular job review site. Through dominance analysis and LDA topic modeling, we found major factors, topics, and keywords of the classified groups by IT, service, and manufacturing domains. Our approach is a novel model to apply the analysis of reviews and text mining to the HR domain, and it will be practically helpful for setting new strategies that improve job satisfaction.
