This study was conducted to explore the coping strategy of Korean men in an international marriage. To achieve this purpose, we selected 4 Korean husbands who had married after seeking the services of matchmaking agencies, and we used snowball sampling. The data were collected through in-depth interviews, and analyzed according to the case study research method. It was found that the men considered international marriage to be their second choice instead of the best one. But they considered their marriage to be 'a prepared marriage', not 'a rash marriage.' 'The prepared marriage' allowed them to have realistic expectations, and to become 'tied in wedlock' with 'a good person.' The Korean husbands coped with difficulties and problems through flexible thinking, such as considering 'how the woman acts depends on the man', 'finding a model mentor couple', 'keeping an open mind to each other', 'reinforcing family ties', and 'developing their wife's independent capacity.' Based on the results, practical alternatives for Korean husbands were suggested. Lastly, the limitations of this study were mentioned.

Dynamical expansion of H II regions plays a key role in dispersing surrounding gas and therefore in limiting the efficiency of star formation in molecular clouds. We use analytic methods and numerical simulations to explore expansions of spherical dusty H II regions, taking into account the effects of direct radiation pressure, gas pressure, and total gravity of the gas and stars. Simulations show that the structure of the ionized zone closely follows Draine (2011)'s static equilibrium model in which radiation pressure acting on gas and dust grains balances the gas pressure gradient. Strong radiation pressure creates a central cavity and a compressed shell at the ionized boundary. We analytically solve for the temporal evolution of a thin shell, finding a good agreement with the numerical experiments. We estimate the minimum star formation efficiency required for a cloud of given mass and size to be destroyed by an HII region expansion. We find that typical giant molecular clouds in the Milky Way can be destroyed by the gas-pressure driven expansion of an H II region, requiring an efficiency of less than a few percent. On the other hand, more dense cluster-forming clouds in starburst environments can be destroyed by the radiation pressure driven expansion, with an efficiency of more than ~30 percent that increases with the mean surface density, independent of the total (gas+stars) mass. The time scale of the expansion is always smaller than the dynamical time scale of the cloud, suggesting that H II regions are likely to be a dominant feedback process in protoclusters before supernova explosions occurs.

We analyze the clustering of large scale structure in the Universe in a model independent method, accounting for anisotropic effects along and transverse to the line of sight. A large sample of 690,000 galaxies from The Baryon Oscillation Spectroscopy Survey Data Release 11 are used to determine the Hubble expansion H, angular distance D_A, and growth rate GT at an effective redshift of z=0.57. After careful bias and convergence studies of the effects from small scale clustering, we find that cutting transverse separations below 40 Mpc/h delivers robust results while smaller scale data leads to a bias due to unmodelled nonlinear and velocity effects. The converged results are in agreement with concordance LCDM cosmology, general relativity, and minimal neutrino mass, all within the $68{\backslash}%$ confidence level. We also present results separately for the northern and southern hemisphere sky, finding a slight tension in the growth rate -- potentially a signature of anisotropic stress, or just covariance with small scale velocities -- but within $68{\backslash}%$ CL.

Purpose: The purpose of the study was to identify and explain the essences and structures of maternal conflicts in Vietnamese married immigrant women in Korea. Methods: A phenomenological methodology was used for the study. Eleven Vietnamese married immigrant women participated in the study. Verbatim transcripts were analyzed using Colaizzi's method. Results: Four categories, 10 clusters and 26 themes emerged from the data for the experience in maternal conflicts of Vietnamese married immigrant women. The four categories were 'An unprepared young motherhood in another culture', 'Feeling left out of the mother's place along the bands of Nap tai tradition', 'My image is like not-being able to stand alone/be independent' and 'Finding hope in motherhood despite of conflicts and stigmas'. Conclusion: Vietnamese married immigrant women experienced not only the negative aspects but also sublimation of maternal conflicts. Based on the results, health professionals need to develop effective nursing interventions toward a positive maternal identity and approach with interculturalism for the Vietnamese married immigrant women in Korea.

Background: We aimed to explore whether levels of patient-centredness, job satisfaction and psychological distress varied between oncology nurses and doctors. Materials and Methods: In a cross-sectional study using self-administered questionnaires, a total of 24 nurses and 43 doctors were assessed for patient-centredness, psychological distress, and job satisfaction using the Patient-Practitioner Orientation Scale, Hospital Anxiety and Depression Scale, and Job Satisfaction Scale. Data were analysed using descriptive statistics, independent samples t-test and MANCOVA, with p<0.05 considered significant. Results: Overall response rate was 95.6% (43/45) for physicians and 85.7% (24/28) for nurses. Even after adjusting for known covariates, our principal finding was that doctors reported greater psychological distress compared to nurses (p=0.009). Doctors also reported lower job satisfaction compared to nurses (p = 0.017), despite higher levels of patient-centredness found in nurses (p=0.001). Findings may be explained in part by differences in job characteristics and demands. Conclusions: Mental health is an important concern not just in cancer patients but among healthcare professionals in oncology.

For those with disabilities, the residential area is the primary place to adapt the disabilities. Since the quality of the area gives a critical impact on their quality of life, it is essential to finding the measures to create the residential environment that supports their independence. In this regard, this study aimed to compare and analyze the interior elements of the houses that hinder the independence of the physically handicapped in the rural and urban areas, and conducted a survey on a total of 80 physically challenged in Seoul and Yeongwol (40 for each area). As a result, the respondents answered that the houses where they are currently living are hindering their independence regardless of area, and there were regional differences in the level of inconvenience with the size of living room, size of utility room, location of room, lighting and heating environment, ventilation system, deteriorated wallpapers and finishing materials, threshold and floor level difference and humidity control. This study has significance by providing the realistic measures to improve the housing environment of the physically challenged living in the rural and urban areas to be customized to them to increase their quality of life.

The purpose of this study was to identify factors affecting the purchases of well-being tea drinks based on the analysis of demographic characteristics, well-being oriented consumer behaviors, and consumer consciousness toward well-being tea drinks. The subjects of this study were undergraduates and graduate students in Seoul. The findings were summarized as follows: 1. Well-being oriented consumer behavior patterns were categorized in three factors; non-dietary life, selective dietary life, and regular/temperate behavior and consumer consciousness toward well-being tea drinks were categorized in two factors; habit/ familiarity and health/ economical efficiency. 2. Multiple regression analysis was used for finding out factors affecting the purchases of well-being tea drinks; independent variables were demographic characteristics(sex, monthly average family income and the amount of personal expenditure), well-being oriented consumer behavior factors and consumer consciousness factors toward well-being tea drinks. Weekly purchase frequency of well-being tea drinks was defined as a dependent variable. As a result, the purchases of well-being tea drinks were influenced in order of regular/temperate behavior, the consciousness of health/ economical efficiency, the amount of personal expenditure and the consciousness of habit/ familiarity. Especially, regular/temperate behavior negatively affected the purchases of well-being tea drinks.

Purpose: This study is aimed at life adaptation process of women with the spinal cord injury. Method: The subjects were 6 women in Kyeonggi and they had interview individually. The study was conducted during June to November in 2009 and developed substantial theory in women's life adaptation process by applying ground research methodology. Result: Motivation for such a change was their psychological pain, which is the central phenomenon. Social activities sustained them during such a process, while social support and experience of achievement acted as an intervention condition. During the initial period, they had a vague expectation that the condition of their accidental spinal cord injury would be improved. Then the expectation had failed, they experienced psychological pain, finding out the reality about the disabled and social difficulties awaiting them. Since then they began to love themselves, pursuing a changed life of hope, achievement and serving. Conclusion: Its result is expected to serve as a basic data for rehabilitation nursing, so that they may conduct independent lives, with a love toward themselves. Repetitive research would be necessary concerning the adaptation process of women in order for the criteria presented to become richer, and for the relations among the criteria to become more refined.

본 논문에서는 소셜 네트워크 게임에서의 이용자들의 사회적 자본과 주관적 행복감의 변화를 살펴보고자 하였다. 이를 위해 소셜 네트워크 게임 이용자들을 대상으로 포커스그룹인터뷰(FGI)를 진행하고, 네트워크 프로그램을 이용해 언어연결망을 분석하였다. 연구 결과 소셜 네트워크 게임에서 사회적 자본은 감소하거나 지인들 사이에서 미미하게 증가하는 것으로 드러났으며, 주관적 행복감은 사회적 자본을 거치지 않고 독립적으로 성취감, 지속적인 돌보기, NPC와의 인터랙션 등의 요인에 영향을 받아 증가하는 것으로 나타났다. 또한, 사회적 자본의 증가가 주관적 행복감에 영향을 미친다는 것을 밝힌 기존의 연구와 달리 사회적 자본의 증가 없이 주관적 행복감이 증가하는 것을 발견하였다는 데에 연구의 의의가 있다.

The low force estimation method of skeletal muscle was proposed by using ICA(independent component analysis) and neuro-transmission model. An EMG decomposition is the procedure by which the signal is classified into its constituent MUAP(motor unit action potential). The force index of electromyography was due to the generation of MUAP. To estimate low force, current analysis technique, such as RMS(root mean square) and MAV(mean absolute value), have not been shown to provide direct measures of the number and timing of motoneurons firing or their firing frequencies, but are used due to lack of other options. In this paper, the method based on ICA and chemical signal transmission mechanism from neuron to muscle was proposed. The force generation model consists of two linear, first-order low pass filters separated by a static non-linearity. The model takes a modulated IPI(inter pulse interval) as input and produces isometric force as output. Both the step and random train were applied to the neuro-transmission model. As a results, the ICA has shown remarkable enhancement by finding a hidden MAUP from the original superimposed EMG signal and estimating accurate IPI. And the proposed estimation technique shows good agreements with the low force measured comparing with RMS and MAV method to the input patterns.
