In order to analyze the organizational performance of government-funded research institutes, four independent variables (organization size, organization age, evaluation system, organization location) and goal ambiguity were empirically analyzed. Although there are existing studies on institutional evaluation, which is the organizational performance of government-funded research institutes, there are differences in research in that it is an empirical analysis analyzed from the perspective of goal ambiguity and that the evaluation system, which is the specificity of institutional evaluation, is included in the analysis. As a result of the analysis, organizational location was the only independent variable that had a direct significant effect on organizational performance, and goal ambiguity showed a significant mediating effect for all independent variables. This indicates that goal ambiguity plays an important role in the organizational performance of government-funded research institutes, and to reduce this, increase the size of the organization, pay attention to establishment of the organization for organizational age, and that it is desirable to have an independent research group in the government department for the organization location. In addition, it was supported that the improvement effect of the evaluation system is proceeding in a desirable direction in terms of goal ambiguity.

This study is to corroborate the relationship between organizational size and performance in the Korean government context. Hence, this study aims to advance research on the relationship between organization size and performance by considering mediating variable: organizational goal ambiguity, which helps understand how organizational size affects organizational goal ambiguity in government and the organizational goal ambiguity has an influence on organizational performance. Bases on theoretical review, we assume that there is the inverted U-shaped relationship between the number of employees and budget size and organizational performance. From the results of path analysis, it shows that organizational size in the Korean government has a negative correlation, "a linear relationship", with organizational performance. Budget size has mediating variables, but the number of employees not. We try to suggest implications on the relationship between organizational size and performance in terms of theoretical perspectives in the context of the Korean government.

This paper examines some syntactic and semantic properties of the negative construction V+bo NP (VbN) in Taiwanese Southern Min (TSM). It finds out that there are ambiguities between an episode reading and a generic reading in VbN construction which require further investigations and explanations. Therefore, the goal of this paper is to account for the ambiguities lying in the negative VbN construction.

This paper addresses solutions th the challenges of carrier phase integer ambiguity resolution and cycle slip detection/identification, for maintaining high accuracy of an integrated GPS/Pseudolite/INS system. Such a hybrid positioning and navigation system is an augmentation of standard GPS/INS systems in localized areas. To achieve the goal of high accuracy, the carrier phase measurements with correctly estimated integer ambiguities must be utilized to update the system integration filter's states. The contribution presents an effective approach to increase the reliability and speed of integer ambiguity resolution through using pseudolite and INS measurements, with special emphasis on reducing the ambiguity search space. In addition, an algorithm which can effectively detect and correct the cycle slips is described as well. The algorithm utilizes additional position information provided by the INS, and applies a statistical technique known as th cumulative-sun (CUSUM) test that is very sensitive to abrupt changes of mean values. Results of simulation studies and field tests indicate that the algorithms are performed pretty well, so that the accuracy and performance of the integrated system can be maintained, even if cycle slips exist in the raw GPS measurements.

This paper addresses solutions to the challenges of carrier phase integer ambiguity resolution and cycle slip detection/identification, for maintaining high accuracy of an integrated GPS/Pseudolite/INS system. Such a hybrid positioning and navigation system is an augmentation of standard GPS/INS systems in localized areas. To achieve the goal of high accuracy, the carrier phase measurements with correctly estimated integer ambiguities must be utilized to update the system integration filter's states. The occurrence of a cycle slip that is undetected is, however, can significantly degrade the filter's performance. This contribution presents an effective approach to increase the reliability and speed of integer ambiguity resolution through using pseudolite and INS measurements, with special emphasis on reducing the ambiguity search space.

본 논문에서는 로봇이 획득한 정보가 내포하는 '장애물의 존재성'과 '장애물 사이의 연결성'이 위치인식에 효과적으로 사용 될 수 있음을 러프집합을 이용하여 확인한다. 그리고 두 속성을 이용하여 위치인식의 애매성을 줄이고, 신뢰할 수 없는 환경 정보에서도 로봇의 위치 판단이 가능한 위치인식 방법을 제안한다. 로봇이 환경 정보를 축소하여 구성한 지도만으로도 목표점까지 이동하는 것을 모의실험을 통해 확인하였다.

사회적으로, 조직들은 보유한 정보 자원의 엄격한 관리를 요구받고 있으며, 정보보안을 위한 기술과 정책에 투자를 높이고 있다. 반면, 조직원에 의한 정보 노출 위협은 지속해서 발생하고 있다. 연구의 목적은 보안정책에 의해 발생할 수 있는 업무 스트레스의 부정적 영향을 감소하는 방안을 제시하는 것이다. 세부적으로, 연구는 조직 환경(보안정책 목표 설정), 개인의 업무 지향성(조절초점) 요소를 반영하여, 업무 스트레스 완화 메커니즘을 제시하고자 하였다. 연구는 정보보안을 엄격하게 활용하고 있는 금융업 근로자에게 설문하였으며, 확보된 309건의 표본을 적용하여 가설을 검정하였다. 분석 결과, 연구는 보안정책 목표 관련 난이도와 구체성이 업무 스트레스(갈등, 모호성)를 감소시키고, 준수 의도에 영향을 주는 것을 확인하였다. 또한, 개인의 업무 향상 초점이 업무 스트레스와 상호작용 효과를 가져, 준수 의도에 미치는 부정적 영향을 축소할 수 있음을 확인하였다. 연구의 결과는 조직원의 보안 준수 강화를 위한 조직의 보안 전략 수립에 의미를 제공한다.

This experimental study has a goal to explore the perceptual sensitivity to phonetic evidence such as duration, phrase accent, or pause in disambiguation. We argue that the realization of the intonational phrasal boundary at the meaningful grammatical boundary in structurally ambiguous sentences facilitates English native listeners to distinguish the meanings of the ambiguous sentences. Moreover, the duration of the phrase-final syllable, pitch range reset, or phrasal tones also provides listeners with important phonetic evidence in disambiguation. In our perception experiment, however, Korean English learners largely depend on the realization of pause. In the results from the perception experiment, all of the groups showed an increase in the response time from the perception of no pause to pause realization. This means that pause at the phonological phrasal boundary plays a role of facilitator to English native speakers with other prosodic cues such as duration, pitch accent, or phrasal tones, while an absolutely important cue to Korean English learners.

The overall goal of this study is to identify what I'||'&'||'R is, and what services should be offered as legitimate I'||'&'||'R actives. The gist of the study is as follows: 1. The shift of the clients targeted to receive the services from disadvantageous to every person. 2. Ambiguity in I'||'&'||'R definition. Because it is hard to distinguish I'||'&'||'R service from the traditional reference service, and shifting of clients, the establishment of the definition was very difficult. Instead of a definite answer, the criteria for "I'||'&'||'R Providers" was drawn. 3. Most provided services were simple and complex information giving based on resource file. Constructing resource file is a major component of I'||'&'||'R service. 4. From 1980s, many I'||'&'||'R providing libraries adapted computer a n.0, pplications. 5. Social work and library-internship was advised to conduct a cooperative project by NCLIS, I'||'&'||'R Task Force. 6. In the high technological era, there continue to be many people who need the su n.0, pportive relationship. I'||'&'||'R is to optimize both the service and clients. Librarian must learn from the principle of high tech/high touch.

Multi-Instance Learning(MIL) performs well to deal with inherently ambiguity of images in multimedia retrieval. In this paper, an effective framework for Contented-Based Image Retrieval(CBIR) with MIL techniques is proposed, the effective mechanism is based on the image segmentation employing improved Mean Shift algorithm, and processes the segmentation results utilizing mathematical morphology, where the goal is to detect the semantic concepts contained in the query. Every sub-image detected is represented as a multiple features vector which is regarded as an instance. Each image is produced to a bag comprised of a flexible number of instances. And we apply a few number of MIL algorithms in this framework to perform the retrieval. Extensive experimental results illustrate the excellent performance in comparison with the existing methods of CBIR with MIL.
