Nearest neighbor query in location-based services has become a popular application. Aiming at the shortcomings of the privacy protection algorithms of traditional ciphertext nearest neighbor query having the high system overhead because of the usage of the double Hilbert curves and having the inaccurate query results in some special circumstances, a privacy protection algorithm of ciphertext nearest neighbor query which is based on the single Hilbert curve has been proposed. This algorithm uses a single Hilbert curve to transform the two-dimensional coordinates of the points of interest into Hilbert values, and then encrypts them by the order preserving encryption scheme to obtain the one-dimensional ciphertext data which can be compared in numerical size. Then stores the points of interest as elements composed of index value and the ciphertext of the other information about the points of interest on the server-side database. When the user needs to use the nearest neighbor query, firstly calls the approximate nearest neighbor query algorithm proposed in this paper to query on the server-side database, and then obtains the approximate nearest neighbor query results. After that, the accurate nearest neighbor query result can be obtained by calling the precision processing algorithm proposed in this paper. The experimental results show that this privacy protection algorithm of ciphertext nearest neighbor query which is based on the single Hilbert curve is not only feasible, but also optimizes the system overhead and the accuracy of ciphertext nearest neighbor query result.

목적: HIV/AIDS환자의 영적 안녕과 영적 요구 정도를 파악하여 간호실무 면에서 HIV/AIDS 환자의 영적 건강 사정과 영적 간호 중재 방안을 마련하는데 기초 자료를 제공하고자 본 연구를 시도하게 되었다. 방법: HIV/AIDS 환자의 영적 안녕과 영적 요구와의 관계를 파악하기 위한 관계성 조사연구(Correlation Survey Research)이며, 연구 대상은 20세에서 70세 사이의 HIV/ AIDS 환자 51명이다. 결과: 1. HIV/AIDS환자의 영적 안녕 점수는 평균 54.59점이었고, 영적 안녕의 하위 영역인 실존적 안녕은 27.78점, 종교적 안녕은 26.80점으로 모두 중 정도 이상으로 나타났다. 따라서 HIV/AIDS환자들은 자신의 영적인 안녕 상태에 대해 중 정도로 지각하고 있다고 볼 수 있으며, 종교적 안녕보다 실존적 안녕의 점수가 높게 나타났다. 2. HIV/AIDS환자의 영적 요구 점수는 평균 108.67점이고 영역별로는 사랑과 관심에 대한 요구가 37.80점, 의미와 목적을 갈망하는 요구가 42.35점, 용서받고 싶은 요구가 28.51점으로 의미와 목적을 갈망하는 요구, 사랑과 관심에 대한 요구, 용서받고 싶은 요구 순으로 높게 나타났다. 3. 영적 안녕과 영적 요구의 상관 관계에서 HIV/AIDS환자의 총 영적 안녕과 총 영적요구는 약한 순 상관관계를 나타냈다(r=0.344, P=0.013). 영적 안녕의 하위영역인 실존적 안녕과는 통계적으로 유의하지 않게 나타났으며, 종교적 안녕과는 순 상관관계를 보였다. 결론: HIV/AIDS환자의 영적 안녕과 영적 요구는 중 정도 수준 이상으로 나타났으며, 영적 안녕과 영적 요구간의 약한 순 상관관계를 나타냈다. HIV/AIDS환자들은 의미와 목적을 갈망하는 요구도가 높으므로 이에 대한 영적 간호를 제공하여 현재 위기 상태의 경험에서 삶의 의미와 목적을 찾도록 하여 실존적 영적 안녕 정도가 증진되도록 지지하고, 앞으로 대상자 수를 확대한 연구와 영적 안녕을 증진시키는 간호 중재에 대한 연구가 계속되어야 하리라고 사료된다.

Background: The aim of this study is to analyze determinants of welfare attitudes toward healthcare services in South Korea, using three main theories: self-interest (positive welfare attitudes if the policy fulfills people's personal interests), symbolic attitudes (positive welfare attitudes if the person is politically progressive or egalitarian), and sociotropic perception (positive welfare attitudes if the person experienced positive aggregated collective experiences of societal events and trends regarding the policy). Although the definition of the welfare attitude is rather ambiguous in literatures, in this investigation, we operationalize the concept as the 'willingness to pay higher taxes to improve the level of health care services for all people in Korea' which shows individuals' actional propensity. Methods: We used the health module from the International Social Survey Program 2011 for the analysis (N= 1,391). Five logistic regression models were built successively using two variables for each theory to measure key concepts of self-interest, symbolic attitudes, and sociotropic perceptions as independent variables. Results: The result showed self-interest and symbolic attitudes factors to be strong determinants of welfare attitudes towards healthcare services in South Korea, whereas sociotropic perception factors have inconsistent effects. Conclusion: For a more politically elaborated healthcare reform in South Korea and elsewhere, there needs to be further research on various dimensions and determinants of welfare attitudes to understand popular basis of welfare expansion, especially in the era of inequality.

Purpose - This study quantitatively examines the level of financial inclusion of a microfinance institution in each region and how this is changing recently, and examines the level of financial inclusion by region and various financial characteristic factors related to it. It was empirically verified what kind of significant impact actually has on the institution's major management performance indicators (stability, profitability, efficiency, and public interest). Design/methodology/approach - It was confirmed that the institution's financial inclusion index declined rapidly after 2015 as a whole, although there were some differences by region depending on regional characteristics. However, considering the fact that the number of branches per 100,000 adult population is steadily increasing nationwide, it was found that, contrary to what is known, the simple decrease in the number of branches of the institution was not the main cause. Findings - The analysis results of this study show that the institution's efforts for financial inclusion have a positive impact on profitability, stability, efficiency, and public interest, and that the institution pursues profitability, efficiency, stability, and public interest. showed that some trade-offs exist. In other words, overall, it was analyzed that profitability of the institution has a positive effect on efficiency, and efficiency has a positive effect on stability and public interest. Research implications or Originality - Since the institution's efforts to improve its profitability do not have a negative impact on its stability and public interest, it is judged that it is important to take a strategic stance, so excessive loan supply that exceeds the scope of the institution's own control needs to be avoided as much as possible. More detailed financial supply strategies and business management capabilities that enhance the asset soundness and management efficiency of safes need to be demonstrated.

The CEOs of global companies have been realized the imagination and creativity that can be obtained from the corporate culture is the crucial competitive power for sustainable growth. Thus, most domestic companies take an increasing interest in how to make creativity efficiently. This paper, however, argues that the proper application of performance indicators can engender creativity and innovation in organizations without costly investing on creativity. Assuming that creativity is actually dominated by the emotion of human resources rather than the rationality, this paper suggests the performance indicators developed based on the viewpoint of the characteristics of human needs and the relationship between the human needs and the attribute of works. The performance system which consists of activity, sociality and creativity is presented and the performance indicators for each category are also suggested to improve the spontaneity and creativity of human resources.

This study was designed to clarify how nurses and nursing students perceive their clients' needs for spiritual nursing care, it's practices, and problems. The purpose was to suggest directions for the development of spiritual nursing practice. The major findings are as follows : Respondents primarily perceived spiritual nursing as nursing care designd to help terminally ill patients accept death. Many of the respondents showed a high level of awareness of spiritual nursing care and its necessity. Few of them, however, bad actual experience in spiritual care. Those with experience in spiritual nursing care tend of take either a religious approach or perceived it as the therapeutic use of the self. The greatest problem related to the practice of spiritual care was found to be lack of time. Most of nurses and nursing students were found to be well aware of the needs for spiritual nursing care but were hindered from practising it because of the lack of time. To resolve the problem it was recommended that the scope of nursing practice be readjusted and that pre-and in-service programs should be developed to further heighten nursing students' interest in spiritual nursing care.
