The purpose of this research is to identify effect of communication strategy as effectively communication method which is decreasing Internet Web site users' perceived information privacy concerns as important factor affecting to positive behavior or behavioral intentions on long-term relational outcome perspectives. This study suggests alternatives concepts and causal relationship about information privacy issues. First, it addressed collaborative communication strategy (CCS) model of effective communication method for Web site's IPP to users. Second, it provided comparing and integrating streams of information privacy research on long-term relational outcomes perspective. Third, it assessed effectiveness of Web site's IPP on organization legitimacy ensured continuous survival of organization. A research model was proposed and subsequent hypotheses were empirically tested with partial least square (PLS) based on 684 responses from the users of 21 Internet Website among entirely finance, recruit, portal /e-store Web site. It was learned that CCS(as a communication method) and relationship quality(representing long-term relational outcomes)was positively associated with decreasing user's IPC more than privacy risk. Also, legitimacy to information privacy practice positively associated with willingness to information providing more than negative effect of IPC. Lastly, their association strength was partially moderated by the type of real information sensitivity.

Purpose: This study was aimed at constructing and examining the effects of a laughter therapy program for elderly patients in long-term care hospitals. Methods: A prospective, two-group quasi-experimental design was used and 50 patients (25 experimental and 25 control group patients) from two long-term care hospitals in Gyeonggido province, South Korea, were study participants. The experimental group received 24 laughter therapy sessions twice a week for 12 weeks, and the control group received laughter therapy after data collection. Data were collected between May 26 and August 17, 2014. Results: The level of cognitive function for the experimental group increased(t=3.27, p=.002). The level of forced vital capacity (t=2.78, p=.008) and forced expiratory volume in 1 second (t=4.94, p<.001) increased among members of the experimental group. Conclusion: These results indicated that the laughter program was effective in improving cognitive and pulmonary functions among older patients who were receiving long-term care in hospitals. This program could be used for community-based elderly patients.

This paper presents a novel analytical formulation for the analysis of composite beams with partial shear interaction stiffened by a bolted longitudinal plate accounting for time effects, such as creep and shrinkage. The model is derived by means of the principle of virtual work using a displacement-based formulation. The particularity of this approach is that the partial interaction behaviour is assumed to exist between the top slab and the joist as well as between the joist and the bolted longitudinal stiffening plate, therefore leading to a three-layered structural representation. For this purpose, a novel finite element is derived and presented. Its accuracy is validated based on short-and long-term analyses for the particular cases of full shear interaction and partial shear interaction of two layers for which solutions in closed form are available in the literature. A parametric study is carried out considering different stiffening arrangements to investigate the influence on the short-and long-term behaviour of the composite beam of the shear connection stiffness between the concrete slab and the steel joist, the stiffness of the plate-to-beam connection, the properties of the longitudinal plate and the concrete properties. The values of the deflection obtained from the finite element simulations are compared against those calculated using the effective flexural rigidity in accordance with EC5 guidelines for the behaviour of elastic multi-layered beams with flexible connection and it is shown how the latter well predicts the structural response. The proposed numerical examples highlight the ease of use of the proposed approach in determining the effectiveness of different retrofitting solutions at service conditions.

A smart home system improves the elderly's quality of life by monitoring and analyzing their movements and health conditions with better health-care and social support services. Therefore, there has been an effort to adopt a smart home system for the independently living elderly. However, to the best of our knowledge, no study has investigated the usability of a smart home system on actual independently living elderly housing in long-term settings. Thus, this study aims to demonstrate the usability of a smart home system on independently living elders in living lab conditions. The BLE smart band and the BLE receiver were chosen for the smart home system to monitor the movement of the participants in their homes as well as to monitor the heart rates, step counts, sleep index. Nine independent living elderly from the senior welfare center in Kimjae participated in this living lab demonstration experiment for ten months. This demonstration experiment confirmed the effectiveness of low-cost and easily adoptable IoT-based BLE sensor sets on independent living elders and discussed the troubles and limitations of the experiment. By grasping the pros and cons of IoT-based BLE sensor sets, this study seeks to improve the accessibility and usability of smart home systems for the elderly population in independent living arrangements.

In this study, a novel improved second order Radial Basis Function Neural Network based method with excellent scheduling capabilities is used for the dynamic prediction of short and long-term energy required applications. The effectiveness and the reliability of the algorithm are evaluated using training operations with New England-ISO database. The dynamic prediction algorithm is implemented in Matlab and the computation of mean absolute error and mean absolute percent error, and training time for the forecasted load, are determined. The results show the impact of temperature and other input parameters on the accuracy of solar Photovoltaic load forecasting. The mean absolute percent error is found to be between 1% to 3% and the training time is evaluated from 3s to 10s. The results are also compared with the previous studies, which show that this new method predicts short and long-term load better than sigmoidal neural network and bagged regression trees. The forecasted energy is found to be the nearest to the correct values as given by England ISO database, which shows that the method can be used reliably for short and long-term load forecasting of any electrical system.

Purpose: In some patients with velopharyngeal insufficiency (VPI), Hypernasality can persist after surgical management. Continuous Positive Airway Pressure (CPAP) is applied to these patients for treating hypernasality. The purpose of this study is to report follow-up results of postoperative CPAP therapy. Methods: After performing palatal lengthening, CPAP therapy was applied to three patients for eight weeks from July of 2008 to November of 2009. Perceptual evaluation, nasometry, and nasopharyngeal endoscopy were performed to evaluate hypernasality, nasalance and size of the gap at velopharyngeal port. Each evaluation was made before surgery, right after CPAP therapy and during follow-up of more than a year after CPAP therapy. Results: All of the patients showed improvement in hypernasality right after CPAP therapy according to the auditory perceptual evaluation, nasometry and nasopharyngeal endoscopy. But the improvement in hypernasality in these patients did not last during follow-up. Conclusion: In this study, our results suggest that CPAP therapy is effective in reducing hypernasality for postoperative VPI patients immediately after the therapy, but hypernasality may be worsen in some patients during follow-up. Therefore we recommend follow-ups after CPAP therapy to see if the efficacy of CPAP therapy lasts.

Internal deficiency of vital Qi is origination of cancer and root cause of its development from the viewpoint of traditional Chinese medicine(TCM). For about 40 years, China has developed a combined system of TCM and Western medical system in treatment of cancers, laying stress on the therapeutic principle of strengthening the body resistance and restoring normal functioning of the body to consolidate the constitution (Fu Zheng Pei Ben). According to the results of the latest clinical and experimental studies, Chinese medicine not only increases curative effectiveness, but also reduces the side effect caused by the toxic, radio and chemical treatment of cancer cases in the western medical system as well as various complications. Long-term taking Chinese herbal medicine prevents recurrence and metastasis of tumor, and heightens long-term curative effectiveness after western medical treatments. It also helps to relieve symptoms, improve the quality of life, and prolong life of terminal cancer patients who have already lost opportunities of western medical treatments. In addition, it can prevent and cure premonitory symptoms of cancer.

Every organization needs to maintain its long-term effectiveness through the positive perceptions, attitudes, and behaviors of its members. Customer orientation, job satisfaction, and organizational citizenship behavior (OCB) are the important functioning aspects for the long-term organizational effectiveness. The purpose of this study is to investigate the impact of service-worker's customer orientation on OCB within Korean bank and insurance sector by analyzing the relationship of constructs in the conceptual model. To achieve research objectives, survey method is employed. Findings of this research reveal that both need and enjoyment dimension of CO are very important in predicting OCB. We sent 220 questionnaires to service workers of the bank and insurance then received 200 valid responses. The research was conducted in bank and insurance agency in J city. The choice of these two types of organizations was dictated by the fact that they have large number of service worker with diverse background at multiple levels in these industries. Results also indicated that the moderating effect of pay satisfaction on the relationship between their OCB and CO had a weak effect.

음주운전은 책임감과 판단력의 부족으로 인하여 사고를 일으키기 쉽다. 한국은 우발적인 음주사고에 대해 실형을 추구하고 있다. 음주 운전자에 대한 집행유예는 전체의 70% 이상을 설명하고 있다. 그러나 보호관찰기간 중에 보호관찰소에 왔던 사람들은 비자발적이었고, 변화에 대한 동기유발이 거의 없었으며, 그들에게 제공된 대규모의 집단적인 단기교육은 재발방지에 한계가 있었다. 소규모의 그룹과 장기교육에 추가하여 우리는 3개월 내에 음주습관의 변화를 살펴보기 위해 집중적인 단기 개입을 시도하였다. 결국, 음주통제의 효과성은 미래 음주운전자들에게 제공될 프로그램을 향상시키는데 있어서 차이를 만들면서 나타날 것이다. 음주운전은 교통사고 원인의 많은 부분을 설명하고 있으며, 그것은 세계의 많은 나라들처럼 음주운전을 막고 처벌하기 위해 노력해야 함을 의미한다.
