This study conducted empirical analyses to investigate the factors affecting the intention to use smart home services. Based on the previous relevant studies, the characteristics of smart home service were found to influence on the intention to use smart home service, and four variables(ubiquitous connectivity, reliability, context awareness, and security) concerning the service characteristics could be derived. And referring to the technology acceptance model(TAM), the updated TAM, IS success model, and the theory of reasoned action(TRA), three variables such as perceived ease of use, perceived usefulness and subjective norm were also likely to affect the intention to use smart home service, and the user innovativeness was inferred to play a role of moderating variable. In order to examine the research model and the hypotheses which could describe the relationship of the above mentioned variables, this study surveyed 447 people who were currently using or would use the smart home services, and then tested the hypotheses for 436 valid responses. The results of hypotheses testing showed that reliability, context awareness, and security have a significant effect on perceived usefulness and on perceived ease of use. However, it was found that ubiquitous connectivity significantly affected perceived usefulness but did not affect perceived ease of use. And perceived ease of use, perceived usefulness and subjective norm had significant effect on the intention to use smart home services. Also, user innovativeness as moderating variable was found to significantly influence on the magnitude of the relationship between ubiquitous connectivity and perceived usefulness and on that between reliability and perceived ease of use. This can be interpreted as the findings implying that innovative smart home-service users are likely to feel the smart home-services more useful than ordinary users when the degree of ubiquitous connectivity is higher, and are likely to perceive the use of smart home-services to be easier than ordinary ones when the degree of reliability is higher.

The purpose of this study was to assess the level of awareness regarding the relationship between systemic diseases and oral health and the importance of education related to this association among dental patients, as well as to identify factors that affect the awareness of the relationship and the perceived need for education. This study was conducted from June 2016 to February 2017. Subjects of this study included outpatients (20-60 years old) from a dental clinic, and only patients who agreed to the survey were included. A total of 110 subjects were included, but the final analysis was based on 92 questionnaires, excluding questionnaires that were inaccurate. Survey questionnaires were completed by self-report and face-to-face interviews with a dental hygienist. The questionnaires covered basic information, awareness of the association between general and oral health, and experience with, and need for education related to, this association. Among the subjects, 48.9% were aware of the association between systemic diseases and oral health. A total of 39.1% of subjects had received education regarding the relationship between systemic diseases and oral health. Subjects who visited dental clinics regularly were 3.94 times (95% confidence intervals [CI]: 1.21-12.84) more likely to be aware of the association between oral health and disease compared with subjects who made only irregular visits to dental clinics. In addition, experience or education was significantly associated with awareness of the relationship between oral health and disease (odds ratio [OR]: 4.64, 95% CI: 1.54-13.93) and the need for education (OR: 3.98, 95% CI: 1.20-13.12). Thus, the dental professionals should provide education on the relationship between oral health and systemic disease in dental clinics to improve patients' awareness and oral health behaviors. These results can be used to strengthen education in the dental clinic.

An information System Audit by the recognition of a problem and suggestions for solutions for overall matters about constructing and managing information systems is needed in order to contribute to the improvement of an information system's quality and improving the performance of projects. In reality, however, the general cognition is that audit is biased by subjective opinions. For this, an auditor needs to measure the level of recognition of the usability and convenience of the technologies of automating audit by applying TAM in the information system audit, and to analyze the relationship with recognition and availability of the interested parties for the technology (tool) of the audit. By the hypothesis verification result, an auditor needs to present objective corroborative facts that back up the level of recognition and usability for the information technology in the field of audit. This study verified that the phenomenon of technology application can be explained and predicted by applying TAM in the field of audit. Through an empirical study of the recognition level of audit and contractor, the developer suggests that the audit plan stage is similar to the audit corrective action stage, but the audit action stage is different from the audit review stage. This research can verify the audit technology preferred for the availability and intention of use and usability.

Das Ziel dieser Abhandlung ist die Unterscheidung zwischen der kognitiven und ontischen Ununterscheidbarkeit. Jene zeigt sich als die Ununterscheidbarkeit, die aus dem Fehler des Identifizierens erfolgt. Diese besteht in der $Selbstidentit{\ddot{a}}t$ jedes individuellen Seienden. Um der Untersuchung der zwei Arten der Ununterscheidbarkeit willen soll die $Identit{\ddot{a}}t$ als Begrifflichkeit von dem Identifizieren als der subjektiven $T{\ddot{a}}tigkeit$ unterschieden werden. $W{\ddot{a}}hrend$ das kognitiv Ununterscheidbare nicht immer das Identische sein kann, ist das ontisch Ununterscheidbare notwendig das Identische. Durch diese Unterscheidung zwischen den beiden Konzeptionen der Ununterscheidbarkeit kann der Sinn des Leibniz'schen Satzes der $Identit{\ddot{a}}t$ des Ununterscheidbaren (principium identitatisindiscernibilium) deutlicher erhellt werden, indem diese Unterscheidung die kritische $Verst{\ddot{a}}rkung$ seines Satzes impliziert. Die Denkbarkeit der Duplikate, die intrinsisch $v{\ddot{o}}llig$ identisch qualifiziert sind, gilt als der bedeutsamste Einwand gegen seinen Satz der $Identit{\ddot{a}}t$. Aber der $Identit{\ddot{a}}tssatz$ - principium identitatis indiscernibilium - ist noch $g{\ddot{u}}ltig$, weil diese Duplikate letztendlich mittels der raumzeitlichen Relationsbeschaffenheit unterscheidbar sind. Hierdurch wird die grundlegende bzw. unentbehrliche Funktion der $Subjektivit{\ddot{a}}t$, die die raumzeitliche Relationsbeschaffenheit $erm{\ddot{o}}glicht$, $erl{\ddot{a}}utert$. $Daf{\ddot{u}}r$ wird Hegels $Erkl{\ddot{a}}rung$ vom $Identit{\ddot{a}}tsbegriff$ und Leibniz bearbeitet.

자동차에서 실내음질은 구매결정 요소들 중의 하나로 그 중요성이 점차 증가하고 있다. 따라서 다양한 운전조건에서 운전자가 기대하는 실내음질의 기대 수준을 충족시켜야 한다. 소비자는 운전경험과 습관에 따라 기대하는 음질에 차이가 있고 소리에 대한 표현방식도 모호하기 때문에 이러한 주관적 특성을 하나의 통일된 표현으로 정의 하기가 어렵다. 그러나 지난 이십여 년 동안의 음질개발과 차량 실내소음 주관평가의 통계처리로 통일된 표현을 할 수 있었다. 나아가 심리음향학 및 신호처리기술의 발달과 꾸준한 음질연구결과로 소리특성을 객관적으로 나타내는 소리의 시각화가 가능하였으며, 운전자가 인식하는 주관평가와의 상관관계를 높여 차량의 대표적인 음질인자로 정량화하여 음질목표를 설정할 수 있었다. 실내소음의 구성은 엔진 투과음, 흡배기 소음, 바람 소음, 도로 기인 소음 등으로 다양하므로 소음원에 따라 음의 균형을 맞추어 조화로운 음질개발을 하는 것이 중요했다. 또한 차량 판매되는 지역에 따라 선호음이 상이하여 지역별 실내음질의 차별화가 필요했다. 궁극적으로는 운전자의 감성품질을 만족할 수 있도록 음을 제어하여 브랜드 사운드를 개발하고 있다. 이러한 실내음질을 달성하기 위한 방법으로 소음원과 전달경로에 대해 기여도를 분석하고, 경로를 구성하는 시스템 별로 세분화하여 시스템 목표를 설정하였다. 시스템 개발에 중요한 인자로 차량의 동강성 및 흡차음 성능을 들 수 있다. 특히 디젤차량의 비중이 큰 유럽업체의 차량의 동강성 및 흡차음 개발 능력은 높게 평가되고 있다. 이에 유럽의 부품전문회사가 가지고 있는 해석과 시험적인 개발 방법을 통하여 전달계 특성을 만족하기 위한 시스템의 동강성 및 흡차음 특성을 개발하고 있다. 차량음질 튜닝의 중요한 기법 중 하나로 흡배기 개발을 추진하고 있다. 친환경자동차인 하이브리드차량, 전기차량 및 연료전지차량의 경우 전기구동부품에서 발생하는 각종 이음 발생을 최소화 했다. 보행자를 보호하고 운전의 즐거움을 향상하기 위한 가상사운드 개발을 진행하고 있다. 회사 수익성 향상을 위한 원가절감 및 구조 경량화에 따른 음질악화와 연비 향상 및 배기가스 규제 강화로 고성능 고출력 엔진탑재에 따른 음질악화 요인을 극복해야 했다. 운전자의 청감은 차량의 운전성에 따라서도 크게 영향을 받게 되므로 엔진제어와 변속기제어를 통해 음질과 운전성이 조화를 이룰 수 있도록 개발하고 있다. 향후, 소음원에 따른 시스템 최적화 개발, 운전성과 음질 연계 개발과 친환경차량의 가상사운드 개발 등이 자동차 음질 개발의 중요한 이슈로 생각한다.

As one of the essential elements of social work practice, knowledge articulates what the social work profession is doing and ought to do. With an emphasis on building a body of knowledge for the profession, this study analyses the nature of social work knowledge. First, the study examines concepts of social work theories and models, which are built around separate clusters of concepts from a broad base of theoretical orientation. The study reviews epistemological and ideological debates over how to perceive and approach social issues and the role of the social work profession. In organizing a clear conceptual framework for social work practice, different frames of reference and selective and fragmentary knowledge from other disciplines are considered barriers. For the development of a clear identity as a unified profession and the prospects of a value-based profession, more attention needs to be given to specify practical knowledge that is contextual and appropriate to practice settings and more sensitive to social issues.

The fuzzy weighted mean classifier is one of the most common classification models and could achieve high performance by adjusting the weights. However, the weights were generally decided based on the experience of experts, which made the resulting classifiers to suffer the lack of consistency and objectivity. To resolve this problem, in this paper, a weight deciding method based on the statistics of the data is introduced, which ensures the learned classifiers to be consistent and objective. To investigate the effectiveness of the proposed methods, Iris data set available from UCI machine learning repository is used and promising results are obtained.
