The purpose of this article is to explain the meanings and uses of the English auxiliaries will morpho-syntactically, and answer the question of whether will is a tense auxiliary or a modal one. Some writers even exclude will completely from the semantics of the modal auxiliaries. They argue that the semantics of will is fundamentally non-modal and has only a few modal-like uses. There are some people who treat will to be semantically separate from the other modal auxiliaries. In the light of modal will, the semantics of will basically remains anchored in volition because the lack of required speaker subjectivity, but has undergone so much semantic bleaching that it may also express future time without volition. On the other hand, the semantics of will in the exclusionist view is erroneous and that its semantics is in fact closely related to the semantics of the other modals. This view reinforces the argument that the morpho-syntactic kinship of will, can, may and must also reflects semantic kinship. It is suggested that all the modal auxiliaries show that the correspondence relation is non-verified but potential. And the specific place that will holds is that the correspondence is unverified at the time of utterance but will turn out to become verified. The overall conclusion is that idiosyncratic morpho-syntax shared by the modals reflects the semantics and pragmatics of the English modal auxiliaries and is forced also to include will.

The global positioning system (GPS) is a useful system in civilian and military applications. However, because of the weak signal, GPS receivers are vulnerable to interference caused by unwanted signals or intentional jammers. To alleviate this issue, a controlled reception pattern antenna (CRPA) array can be employed to adaptively place radiation pattern nulls toward the direction of the signal interference. The performance of the CRPA array improves as the number of antenna elements increases. Therefore, antenna miniaturization is highly desirable for CRPA applications. We designed a compact CRPA array based on seven electrically miniaturized microstrip patch antennas (MPAs) on a 5-inch ground platform. We used a non-Foster matching circuit to match efficiently miniaturized MPAs on an FR-4 substrate. Experimental results show that the non-Foster matching circuit significantly improves such elements of antenna performance as return loss and antenna gain. In addition, we confirmed that the mutual coupling of the proposed CRPA array is less than -45 dB.

The purpose of the study is to investigate whether monetary and non-monetary incentives paid to exporters influence the level of compliance and tendency to behave opportunistically. As one of the most common ways to export one's products overseas is to establish relationships with foreign agents, numerous research has aimed to identify types of incentives to motivate foreign agents to bring the most efficient outcomes. Stemming from previous studies, this research hypothesizes that the type of incentives affects exporter's level of compliance, and tendency to act opportunistically which determine the level of exporter's satisfaction on foreign agency role performance. Data was collected from 196 Korean exporters, and the findings suggest that exporters should actively engage in providing non-monetary incentives to their agents to motivate importers to comply with exporter's rules. Conversely, agents tend to act more opportunistically when they receive monetary incentives only. These phenomena lead to the conclusions that the satisfaction level of foreign agency role performance is improved when non-monetary incentives are actively in place, and at the same time, foreign agent's level of compliance and opportunism play mediating roles.

Various methods have been proposed for the time series prediction. Most of the conventional methods only optimize parameters of mathematical models, but to construct an appropriate functional form of the model is more difficult in the first place. We employ the Genetic Programming (GP) to construct the functional form of prediction models. Our method is distinguished because the model parameters are optimized by using Back-Propagation (BP)-like method and the prediction model includes discontinuous functions, such as if and max, as node functions for describing complicated phenomena. The above-mentioned functions are non-differentiable, but the BP method requires derivative. To solve this problem, we develop ...

Background: This study aimed to analyze the impact of community health care resources on the place of death of older adults with dementia compared to those with cancer in South Korea, using public administrative big data. Methods: Based on a literature review, we selected person- and community-level variables that can affect older people's decisions about where to die. Data on place-of-death and person-level attributes were obtained from the 2013 death certification micro data from Statistics Korea. Data on the population and economic and health care resources in the community where the older deceased resided were obtained from various open public administrative big data including databases on the local tax and resident population statistics, health care resources and infrastructure statistics, and long-term care (LTC) insurance statistics. Community-level data were linked to the death certificate micro data through the town (si-gun-gu) code of the residence of the deceased. Multi-level logistic regression models were used to simultaneously estimate the impacts of community as well as individual-level factors on the place of death. Results: In both the dementia (76.1%) and cancer (87.1%) decedent groups, most older people died in the hospital. Among the older deceased with dementia, hospital death was less likely to occur when the older person resided in a community with a higher supply of LTC facility beds, but hospital death was more likely to occur in communities with a higher supply of LTC hospital beds. Similarly, among the cancer group, the likelihood of a hospital death was significantly lower in communities with a higher supply of LTC facility beds, but was higher in communities with a higher supply of acute care hospital beds. As for individual-level factors, being female and having no spouse were associated with the likelihood of hospital death among older people with dementia. Conclusion: More than three in four older people with dementia die in the hospital, while home is reported to be the place of death preferred by Koreans. To decrease this gap, an increase in the supply of end-of-life (EOL) care at home and in community-based service settings is necessary. EOL care should also be incorporated as an essential part of LTC. Changes in the perception of EOL care by older people and their families are also critical in their decisions about the place of death, and should be supported by public education and other related non-medical, social approaches.

본 연구의 목적은 관광안내서 등 현대 도시사회에서 시민들의 여가와 관광활동의 정보매체가 되는 비학술문헌의 분석을 통하여 탐방선호장소들의 장소적 특성을 연구하려는 것이다. 연구범위와 방법은 서울 내의 유형별 탐방명소들을 대상으로 관광안내문헌에 나타나는 장소별 빈도와 내용분석을 통해 대표적 장소적 특성을 규명하려 하였다. 유형별 탐방명소는 '자연형 탐방명소', '역사형 탐방명소', '생활문화형 탐방명소'로 대별되었다. 유형별 대표장소는 빈도분석에 의해 각각 남산과 한강, 덕수궁과 경복궁, 이태원과 대학로로 선정하였다. 상기 문헌연구와 이를 보완하는 현장연구를 종합하여 전도시적 차원, 주변맥락의 차원, 장소적 차원의 세 단계에서 서울 탐방명소의 장소적 특성을 도출, 해석하였다. 각 유형간의 차이에도 불구하고 세 유형이 공유하는 지배적인 장소적 특성은 배경을 이루는 도시공간과의 가시적, 용도적 '대비성'과 주변지역과의 활동적, 의미적 '연계성', 그리고 단위 탐방명소 내부에서의 '가시성'과 '체험성'이라고 할 수 있다. 즉, 배후도시의 환경과는 가시적, 용도적으로 명료하게 대비되면서 주변지역들과는 연계 관광적 여건이 원활하고, 장소 내부에서는 가시적 독특함과 체험적 다양성이 갖추어질 때 탐방명소로서 효과가 강화될 수 있다고 파악되었다. 본 연구결과는 동시대 사람들이 느끼는 도시 탐방명소의 보편적 매력요인이자 장소적 특성으로 볼 수 있으며, 향후 이들 특성들을 강화하는 방향으로 탐방명소와 그 주변의 도시환경을 조성, 관리할 때 도시 전반의 정체성과 관광효과를 증진시킬 수 있을 것으로 기대된다.
