This study has been performed to explore verbal and behavioral expression of sexual desires among male elderly residents who have been living in long tenn care facilities. There are three topics covered in this study; first, in what situations and how seriously do care workers encounter expression of sexual desires of the elderly residents? Second, what kind of negative consequences do they believe those sexual behaviors will lead to? Third, how can we implement defensive measures against the sexual behaviors? In this study, twenty three care workers working full time in five retirement and care facilities were asked about their experience and perception of the above study agendas, and answers of the qualitative interview were drawn as follow; first, the elderly residents apparently show a variety of sexual harassment and provoking behaviors such as sticking to specific women, physically touching and attacking, and induce obscenely activities against female residents, care workers, and volunteer visitors. Second, their sexual behaviors are often influenced by their isolated and abandoned emotionality as well as living situation in rural areas. Third, their sexual behaviors often critically affect care work plan and facility managements by severely discouraging female care givers and community supporters. Therefore in this study, suggestions and defensive measures were made as follows: first, education and counselling programs toward female workers and volunteers need to be developed, and the programs should cover psychological and behavioral mechanism of sexuality in later life. Second, self control plans need to be empowered toward the elderly residents; in the plans, the elderly residents shall be encouraged to evaluate primary cause and proper solutions of sexual behaviors of their peering residents. Third, combination of healthy housing and care facilities for frail elderly need to be integrated in a neighboring location, so that when residents and workers encounter extreme episodes of sexuality of healthy residents in a housing facility, the problematic sexual residents are partially transferred into a neighboring care facility and thereafter other residents and cafe givers are relieved from stressful contacts with the extremely sexual residents.

In many continuous speech recognition systems, phoneme is used as a basic recognition unit However, the coarticulation generated among neighboring phonemes makes difficult to recognize phonemes consistently. This paper proposes allophone as an alternative recognition unit. We have classified each phoneme into three different allophone groups by the location of phoneme within a syllable. For a recognition algorithm, time-delay neural network(TDNN) has been designed. To recognize all Korean allophones, TDNNs are constructed in modular fashion according to acoustic-phonetic features (e.g. voiced/unvoiced, the location of phoneme within a word). Each TDNN is trained independently, and then they are integrated hierarchically into a whole speech recognition system. In this study, we have experimented Korean plosives with phoneme-based recognition system and allophone-based recognition system. Experimental results show that allophone-based recognition is much less affected by the coarticulation.

Korean administrative jurisdiction has changed from separation to integration system, without definite raison d'etre from the effectiveness dimension. It partially comes from the fact that the top priority of most existing documents has given to the behavioral patterns of key variables during specific time periods. As an alternative approach, this study focuses on dynamic analysis on the long-term structural patterns related to urban-rural integration issues. Specifically, it pays attention to unique experiences between two neighboring administrative authorities, namely Cheongju and Cheongwon, all of which have repeated exceptional confrontations between pros and cons over almost two decades. From the theoretical perspectives, this observes structural similarities and differences between separation and integration approaches and compares individual feedback loops in order to examine urban-rural integration effectiveness. Structurally, if the integrated local authority adopts systematic management and balanced territorial development principles, it would gain the highest positive effect of urban-rural integration. After scenario buildings, it analyzes administrative integration dynamics between Cheongju and Cheongwon, highlighting geo-political conditions, key issues, and implementation plans between two administrative authorities. It expects that the integrated jurisdiction as a whole would increase the urban attractiveness as it can facilitate territorial development plans from macro-level. Furthermore, if the integrated authority keeps balanced territorial principles, which would be well reflected in the mutual agreement between two administrative units, it would also guarantee the increased urban attractiveness in the integrated jurisdiction. Nonetheless, compared to Cheongwon, which might be wider open to the location of NIMBY facilities, it would be more difficult for Cheongju to pay attention to territorial development confined to its original jurisdiction in the short run.

This paper, which covers a fluorescence microscopy image of brain tumor cells, looks at drug reactions by treating different types and concentrations of drugs on a plate of $24{\times}16$ wells. Due to the limitation of the field of view, a well was taken into 9 field images, and each has an overlapping area with its neighboring fields. To analyze more precisely, image stitching is needed. The basic method is finding a similar area using normalized cross-correlation (NCC). The problem is that some overlapping areas may not have any duplicated cells that help to find the matching point. In addition, the cell objects have similar sizes and shapes, which makes distinguishing them difficult. To avoid calculating similarity between blank areas and roughly distinguishing different cells, thresholding is added. The thresholding method classifies background and cell objects based on fixed thresholds and finds the location of the first seen cell. After getting its location, NCC is used to find the best correlation point. The results are compared with a simple boundary stitched image. Our proposed method stitches images that are connected in a grid form without collision, selecting the best correlation point among areas that contain overlapping cells and ones without it.

집적회로 시스템이 고집적화 됨에 따라, 연결선은 회로 전체 성능을 결정하는 중요한 요소가 되었다. 버퍼 삽입은 연결선의 성능 향상의 효과적인 방법이다. 하나의 신호선이 허용 범위를 넘는 전달지연시간을 가질 때, 우리는 하나 또는 그 이상의 버퍼를 삽입하여 지연시간을 줄일 수 있다. 이제까지 많은 연구들에서 하나의 신호선에 대해 버퍼를 삽입하는 방법을 개발하였으나, 우리는 여러 신호선에 동시에 버퍼 위치를 찾아 버퍼를 삽입하는 방법을 연구하였다 이 방법은 여러 개의 신호선에 버퍼를 삽입하는 위치를 찾는 어려움을 효과적인 방법을 이용하여 그 위치를 결정한다. 또한 본 연구에서는 fan-out이 여럿인critical path에 대해서도 버퍼 삽입으로 지연시간을 최적화하는 기술을 개발하였다. 이 방법은 Elmore Delay 모델을 이용하여 지연시간을 계산하고 각 신호선에 지연시간을 최적화 할 수 있는 버퍼를 결정한다.
