Purpose: The purpose of this study is to discover the nature from the life experience of a person with unilateral acquired blindness and his/her family after losing the eyesight and adapting in the environment and to find the meaning of life and how to solve the problem in psychosocial aspect. Methods: This study uses one of the qualitative research methods which explains how families with the unilateral acquired blind perceive blindness after experiencing it and observes how they signify it. starts with interest in lifestyles of individuals and their families and tries to understand the subjective existences of participants in accessible ways and draw the experiences after becoming one-side blind. It cyclically uses deductive verification process through inductive method and establishing hypothesis using materials. Results: According to the results of this study, unilateral acquired blindness studies, due to shattered life, they did not know what to do. Also, discomfort from struggling in a big tunnel and even will to live were found. trying to go out to the world, seeing the new world, and trying to encourage myself, strong attachment to life was shown to by saying, appeared. Each includes sub-topics such as feeling abandoned after confirmed the blindness, feeling disappointed to doctors, family, and friends, trying to live with hope, struggling in a tunnel with thinking how to live, closing the mind from the world, seeing outside the world in the midst of struggling, trying to forget the past with the will of life, having hope to live with care of family, and trying to keep the rest vision. Conclusion: Firstly, in nursing aspect for their adaptation, programs for disable people and nursing intervention focused on their families should be developed. Secondly, since it can be economic and psychological burden for their families and acquaintances, it is necessary to support the blind so that they can find fitted rehabilitation programs and come back to society. Thirdly, active participation of health care providers may influence social interest the improvement of national welfare policy for the unilateral acquired blind.

Background: The current lack of the number of nurses and high nurse turnover rate leads to major problems for the health-care system in terms of cost, patient care ability, and quality of care. Theoretically, burnout may help link emotional labor with turnover intention. The purpose of this study was to investigate the mediating effect of burnout in the association between emotional labor and turnover intention in Korean clinical nurses. Methods: Using data collected from a sample of 606 nurses from six Korean hospitals, we conducted a multiple regression analysis to determine the relationships among clinical nurses' emotional labor, burnout, and turnover intention, looking at burnout as a mediator. Results: The results fully and partially support the mediating role of burnout in the relationship between the subfactors of emotional labor and turnover intention. In particular, burnout partially mediated the relationship between emotional disharmony and hurt, organizational surveillance and monitoring, and lack of a supportive and protective system in the organization. In addition, we found that burnout has a significant full mediation effect on the relationship between overload and conflicts in customer service and turnover intention. Although the mediating effect of burnout was significantly associated with the demands and regulation of emotions, no significant effects on turnover intention were found. Conclusion: To reduce nurses' turnover, we recommend developing strategies that target both burnout and emotional labor, given that burnout fully and partially mediated the effects of emotional labor on turnover intention, and emotional labor was directly associated with turnover intention.

One of the most performed action in daily life is standing up from sitting position. As the population of the world is aging at the high rates, people may face problems with reduced muscle strength as well as psychological changes. This can lead elderly people having difficulties with standing up from chair. Now, with the aging trend worldwide, products are being developed that can support the lives of the elderly. This study examines the distribution of hip pressure in relation to the seating positions of the standing assistance seats under development to prevent standing up accidents in older adults. The currently developing standing assistant chair designed to tilt to a maximum angle of 25 degrees. At over $25^{\circ}$, design considers that older people are at risk of thrown back out of that force and that the forces exerted on their arms and legs can be a significant burden to older people. By considering danger of higher than $25^{\circ}$ for older people which is experimented in the basis of static capturing approach in previous papers, it is experimented people with age group of 20~60 on $0^{\circ}$ to $25^{\circ}$ tilting angle on the basis of dynamic capturing method in order to pick convenient angle of inclination. Moreover, tried to find the optimum angle by comparing the hip pressure distribution when seated at the edge of the seat and at the center of the seat with the pressure distribution sensor.

Background: Nutrient release during litter decomposition was investigated in Vitex doniana, Terminalia avecinioides, Sarcocephallus latifolius, and Parinari curatellifolius in Makurdi, Benue State Nigeria (January 10 to March 10 and from June 10 to August 10, 2016). Leaf decomposition was measured as loss in mass of litter over time using the decay model W_t/W₀ = e-^{kd t}, while $Kd=-{\frac{1}{t}}In({\frac{Wt}{W0}})$ was used to evaluate decomposition rate. Time taken for half of litter to decompose was measured using T₅₀ = ln ²/k; while nutrient accumulation index was evaluated as $NAI=(\frac{{\omega}t\;Xt}{{\omega}oXo})$. Results: Average mass of litter remaining after exposure ranged from 96.15 g, (V. doniana) to 78.11 g, (S. lafolius) in dry (November to March) and wet (April to October) seasons. Decomposition rate was averagely faster in the wet season (0.0030) than in the dry season (0.0022) with P. curatellifolius (0.0028) and T. avecinioides (0.0039) having the fastest decomposition rates in dry and wet seasons. Mean residence time (days) ranged from 929 to 356, while the time (days) for half the original mass to decompose ranged from 622 to 201 (dry and wet seasons). ANOVA revealed highly significant differences (p < 0.01) in decomposition rates and exposure time (days) and a significant interaction (p < 0.05) between species and exposure time in both seasons. Conclusion: Slow decomposition in the plant leaves implied carbon retention in the ecosystem and slow release of CO₂ back to the atmosphere, while nitrogen was mineralized in both seasons. The plants therefore showed effectiveness in nutrient cycling and support productivity in the ecosystem.

Purpose: The purpose of this study was to explore decision making experiences of Korean women with breast cancer who underwent breast reconstruction with/after a mastectomy. Methods: Data were collected during 2015-2016 through individual in-depth interviews with 10 women who had both mastectomy and breast reconstruction, and analyzed using phenomenological method to identify essential themes on experiences of making a decision to have breast reconstruction. Results: Five theme clusters emerged. First, "expected loss of sexuality and discovery of autonomy" illustrates various aims of breast reconstruction. Second, "holding tight to the reputation of doctors amid uncertainty" specifies the importance of a trust relationship with their physician despite a lack of information. Third, "family members to step back in position" describes support or opposition from family members in the decision making process. Fourth, "bewilderment due to the paradox of appearance-oriented views" illustrates paradoxical environment, resulting in confusion and anger. Lastly, "decision to be made quickly with limited time to oneself" describes the crazy whirling process of decision making. Conclusion: Findings highlight aims, worries, barriers, and facilitators that women with breast cancer experience when making a decision about breast reconstruction. Deciding on breast reconstruction was not only a burden for women in a state of shock with a diagnosis of breast cancer, but also an opportunity to decide to integrate their body, femininity, and self which might be wounded from a mastectomy. These findings will help oncology professionals provide effective educational counselling before the operation to promote higher satisfaction after the operation.

이동통신 로밍(roaming)을 하는 경우 외부망(visited network)의 사용 요금이 홈망(home network)에 비해 높게 책정된다. 따라서, 단말이 외부망에 위치하다가 본인의 홈망으로 복귀했는데도 불구하고 여전히 외부망에 등록되어 있는 경우, 사용자의 의도와 무관하게 높은 통신요금이 책정되는 경우가 있다. 이와 같은 문제점은 같은 지역에 여러 사업자의 망이 중복되어 설치된 경우에 자주 발생하는데, 실례로 폴란드 이동통신망 사례를 들 수 있다. 이에 본 논문에서는 이동통신 로밍 사용자의 빠른 홈망 복귀를 위한 망탐색 알고리즘을 제안한다. 제안 기법은 3GPP 규격의 망탐색 동작을 따르면서 단말에 저장된 망정보 DB를 활용하여 홈망을 탐색하는 방식이다. 제안 기법의 성능평가를 위해 실제 단말기와 실험장비를 이용하여 폴란드 사업자 환경을 가상적으로 구축하였다. 실험 결과, 제안 방식이 기존 3GPP 규격 방식에 비해 홈망 복귀시간을 3~60분까지 단축시킬 수 있음을 확인하였다.

This study aims to lay the foundations for domestic welfare through solving domestic problems. The major results of this study were as follows: First, there are many domestic violence facilities, but their poor financial condition and lack of human resources make it difficult to meet all need of shelter users. Second, people who use domestic violence shelters can't receive proper care and they go back to their homes in which violence still remains. It is like a vicious cycle making their situation worse and worse. Third, counseling given to abused women in shelters is arranged individually or in groups, but there are not enough programs providing proper care for them. On the basis of the realities mentioned above, this study was intended to pave the way to work out the improvement programs as follows: First, it is critical that the financial support from the government should be increased. Second, it is necessary to improve the training of personnel concerned with the handling of domestic violence cases. Third, it is important to make sure that children of abused women should be taken care of safely, and temporary jobs for the women should be secured. This will allow domestic violence shelters to serve their true purpose. Lastly, more adequate counseling services such as more instrumental 1366 phone lines, the development of various programs and the follow-up counseling should be reinforced.

This paper proposes intelligent control of a virtual walking machine that can generate infinite floor for various surfaces and can provide proprioceptive feedback of walking to a user. This machine allows users to participate in a life-like walking experience in virtual environments with various terrains. The controller of the machine is implemented hierarchically, at low-level for robust actuator control, at mid-level fur platform control to compensate the external forces by foot contact, and at high-level control for generating walking trajectory. The high level controller is suggested to generate continuous walking on an infinite floor for various terrains. For the high level control, each independent platform follows a man foot during the swing phase, while the other platform moves back during single stance phase. During double limb support, two platforms manipulate neutral positions to compensate the offset errors generated by velocity changes. This control can, therefore, satisfy natural walking conditions in any direction. Transition phase between the swing and the stance phases is detected by using simple switch sensor system, while human foot motions are sensed by careful calibration with a magnetic motion tracker attached to the shoe. Experimental results of walking simulations at level ground, slope, and stairs, show that with the proposed machine, a general person can walk naturally on various terrains with safety and without any considerable disturbances. This interface can be applied to various areas such as VR navigations, rehabilitation, and gait analysis.
