In this article, I have analyzed the signification of the death of Don Quijote from the oriental religious and philosophical point of view, comparing with the novels of Kim, DongRi. We are able to read Cervantes' hope for his absolute ideal to be lasting forever via the death of Don Quijote, in the base of a strong will named of Gukyeong's life. In the same time, we can also discovery death as lasting of life in the basis of buddhist idea and death as the unification with nature via the meeting between the living and the dead in the Montesinos Cave. Montesinos Cave symbolizes a unclassified and chaotic space, which the Shamanist can meet the dead with a extatic ceremony and both supernatural life and daily life coexist. Therefore, the symbolic death of Don Quijote in Montesinos Cave is abe to be explained by approaching to absolute freedom named of Hatal, in other words, voluntary and conscious death to escape from the yugo of being. Considering the fact that Kim, Dongri emphasized on the unification of sky, earth and human being, keeping a racial identification in the face of the stream of occidental materialism in the time of Japanese conquest, we can look for the similarity with Cervantes' ideal. Contrary to the religious dogmatic ideal, Cervantes treated to recover the human nature and vitality, transcending the occidental rationalism and religious ideology in the time of Counter-reformation.

Interest is increasing in electrocardiogram (ECG) signal analysis for embedded devices, creating the need to develop an algorithm suitable for a low-power, low-memory embedded device. Linear approximation of the ECG signal facilitates the detection of fiducial points by expressing the signal as a small number of vertices. However, dynamic programming, a global optimization method used for linear approximation, has the disadvantage of high complexity using memoization. In this paper, the calculation area and memory usage are improved using a linear approximated template. The proposed algorithm reduces the calculation area required for dynamic programming through local optimization around the vertices of the template. In addition, it minimizes the storage space required by expressing the time information using the error from the vertices of the template, which is more compact than the time difference between vertices. When the length of the signal is L, the number of vertices is N, and the margin tolerance is M, the spatial complexity improves from O(NL) to O(NM). In our experiment, the linear approximation processing time was 12.45 times faster, from 18.18 ms to 1.46 ms on average, for each beat. The quality distribution of the percentage root mean square difference confirms that the proposed algorithm is a stable approximation.

Mild cognitive impairment (MCI) is a clinical syndrome characterized by the onset and evolution of cognitive impairments, often considered a transitional stage to Alzheimer's disease (AD). The genetic traits of MCI patients who experience a rapid progression to AD can enhance early diagnosis capabilities and facilitate drug discovery for AD. While a genome-wide association study (GWAS) is a standard tool for identifying single nucleotide polymorphisms (SNPs) related to a disease, it fails to detect SNPs with small effect sizes due to stringent control for multiple testing. Additionally, the method does not consider the group structures of SNPs, such as genes or linkage disequilibrium blocks, which can provide valuable insights into the genetic architecture. To address the limitations, we propose a Bayesian bi-level variable selection method that detects SNPs associated with time of conversion from MCI to AD. Our approach integrates group inclusion indicators into an accelerated failure time model to identify important SNP groups. Additionally, we employ data augmentation techniques to impute censored time values using a predictive posterior. We adapt Dirichlet-Laplace shrinkage priors to incorporate the group structure for SNP-level variable selection. In the simulation study, our method outperformed other competing methods regarding variable selection. The analysis of Alzheimer's Disease Neuroimaging Initiative (ADNI) data revealed several genes directly or indirectly related to AD, whereas a classical GWAS did not identify any significant SNPs.

기존의 네트워크 토폴로지 기반 애드혹 라우팅 프로토콜들은 차량간 통신 환경에 적용할 경우 차량의 높은 이동성에 기인한 빈번한 네트워크 토폴로지의 변화로 인해 높은 경로 재설정 부하가 발생하기 때문에 적합하지 않다. 위치 기반 라우팅 프로토콜은 부수적인 경로 설정 과정이 없기 때문에 일반적으로 차량간 통신 환경과 같이 이동성이 높은 환경에 적합한 것으로 알려져 왔다. 그러나 위치 정보의 획득 및 유지를 위한 위치정보 제공 서비스와 같은 추가적인 과정이 필요하며 위치 정보의 부정확성으로 인한 프로토콜의 오작동성 문제가 존재한다. 본 논문에서는 수신한 데이타의 주소 정보를 이용하여 도달 가능한 목적지 노드들의 목록을 유지하고 이 정보를 이용하여 경로 설정 과정 및 위치 정보와 같은 추가적인 정보의 사용 없이도 멀티 홉 패킷 포워딩이 가능한 MMFP(Multi-hop MAC Forwrarding Protocol)을 제안한다. MMFP는 시간 종속적인 기능들의 정화한 동작을 위하여 IEEE 802.11 MAC 계층을 확장하여 설계하며 실제 도로 환경을 모델링 한 실험 시나리오를 이용한 실험을 통하여 AODV보다 높은 성능을 나타냄을 보인다.

In the past, buyers and suppliers met each other to find common interests off-line in exhibitions and conferences, or through personal connection. These activities were time consuming and costly. With the advent of information era, these activities moved to online market places, where buyers search for suppliers with a set of keywords that are believed to be representative of their requirements. Its fundamental assumption is that all the potential candidates are registered in a certain database. However, recently buyers want to diversify suppliers due to needs of cost competitiveness or frequent new product development. To this end, instead of choosing suppliers from the supplier pool, discovering suppliers from all over the world should be emphasized. In order to enable buyers to describe their requirements and suppliers to capture their manufacturing capabilities via online market places, the semantic differences of terms between buyers and suppliers should be resolved. The paper summarizes various supplier discovery frameworks and prototype systems, which can be employed to expose domestic small-medium enterprises into global buyers in the near future.

The purpose of this study is to consider of meaning in life based on Frankl's theory and to propose of hospice nursing according to conceptual framework of meaning in life. The conceptual framework of meaning in life is composed of 4 phases. According to the first phase, acceptance & awareness of self and life, hospice nurse should helps dying patient to accept limitedness of human existence and death. and according to the second phase, actualization of creative value, hospice nurse can helps dying patient to discover meaning in life through doing a deed for last time before his death. According to the third phase, actualization of experiential value, hospice nurse can helps them to discovery of meaning by experiencing of love through meetings with other people, nature, and god. According to the forth phase, actualization of attitudinal value, hospice nurse can helps them to discovery of meaning by realizing meaning in suffering and death through exercising of the inner freedom to choose bravery and acceptance in the face of death and misfortune. As mentioned above, the Frankl's theory accords with the core of hospice nursing that helps people to accomplish human essence in suffering and death. therefore we accepted Frankl's point of view, asserted that one of the most important roles of a hospice nurse as a supporter and sustainer for dying patients is to help patients to find meaning in life even in the course of death. To achieve the goal, hospice nurses should try to have a firm faith through philosophical introspection about life, death, human existence and meaning in life what the most important goal of life is to discover meaning in life and human have the duty and responsibility of recognizing and pursuing meaning up to the last moment of life.

Delay in seeking treatment for breast cancer is a barrier to the early diagnosis and management of the disease, resulting in a poorer prognosis. We here estimated the prevalence of delayed presentation for breast cancer and identified possible influential sociodemographic factors in a cross-sectional study of 250 patients diagnosed with primary breast cancer at the Radiotherapy and Oncology Clinic in Kuala Lumpur Hospital. Data were collected by face-to-face interview using a structured questionnaire and from medical records. We examined associations between delayed presentation (presenting to a physician more than 3 months after self-discovery of a symptom) and sociodemographic characteristics, practice of breast self examination (BSE), history of benign breast disease, family history of breast cancer and type of symptom, symptom disclosure and advice from others to seek treatment using multiple logistic regression. Time from self-discovery of symptom to presentation ranged from tghe same day to 5 years. Prevalence of delayed presentation was 33.1% (95%CI: 27.4, 39.3). A significantly higher proportion of delayers presented with late stages (stage III/IV) (58.3% vs. 26.9%, p<0.001). Divorced or widowed women (OR: 2.23, 95% CI: 1.11, 4.47) had a higher risk of delayed presentation than married women and women who never performed breast self examination were more likely to delay presentation compared to those who regularly performed BSE (OR: 2.74, 95% CI: 1.33, 5.64). Our findings indicate that delayed presentation for breast cancer symptoms among Malaysian women is high and that marital status and breast self examination play major roles in treatment-seeking for breast cancer symptoms.

LTE (Long Term Evolution) 및 LTE-A (Long Term Evolution-Advanced) 망에서는 사용자에 대한 시스템 용량 향상을 위해 펨토셀(femto-cell)을 이용한 계층적(hierarchical) 셀 구조를 고려하며, LTE/LTE-A에서 고려되는 펨토셀은 일반적으로 특정 개인 및 집단에 제한된 접속을 허용하는 배타적 접속(Closed Subscriber Group; CSG) 펨토셀로 구현된다. 하지만 이러한 배타적 접속 펨토셀이 보편화되기 위해서는 배타적 접속 펨토셀로의 진입(inbound) 핸드오버(handover) 지연시간 문제를 해결해야 한다. 특정 단말(User Equipment; UE)에게만 접속이 허용된 배타적 접속 펨토셀은 제한된 지역에만 분포하여 셀 검출 시도의 빈도가 낮을 수 밖에 없으므로 일반적인 매크로셀(macro-cell)에 비해 셀 검출에 보다 많은 시간이 소요되며, 이로 인한 진입 핸드오버 지연이 발생한다. 이러한 배타적 접속 펨토셀에 대한 검출을 고려하지 않은 LTE/LTE-A 단말을 이용하여 접속이 허용된 배타적 접속 펨토셀 검출을 시도할 경우 현재 표준에서 제시하는 셀 검출에 대한 성능 기준을 충족시키지 못할 수 있으며, 따라서 본 논문에서는 현재 LTE/LTE-A 표준에 따른 기본적인 셀 검출 방식을 이용하여 LTE 배타적 접속 펨토셀에 대한 검출 성능평가를 수행하고 문제점을 분석하여, LTE 배타적 접속 펨토셀에 대한 진입 핸드오버 지연 문제를 해결할 수 있는 근거를 제시하고자 한다.
