The present study was performed to analyze the infection status of trematode metacercariae in fishes caught from Chunamchosuchi (pond) located in Uichang-gun. Kyongsangnam-do. A total of 130 freshwater fish of 5 species was collected by a fish net and fish traps from November, 1995 to May, 1996. They were examined under a stereomicroscope after artificial digestion with pepsin-HCI solution. A total of 8 species or metacercaria, i. e. Clonorchis sinensis, Echinochnsnw japonicas, Cvathocotwle orientalis, Diplostomun sp.. Metorchis orientalis. Holostephcnw nipponicw, Exorchis oviformis and unidentified echinostome, was detected from them. The metacercariae of C. sinenesis were found in 8/20 (40.0%) Accnthorhodeus Qsmwsi, 20/20 (100%) Cutter breuiccudc, 31/45 (68.9) Cultriculus eigenmanni and 21/25 (84.0%) Pseunorasborc pronga, and the average number of metacercariae detected in each fish species were 1.9, 31.7. I5.3, and 73.0. From the above results, it was confirmed that fresh-water fishes from Chunamchosuchi (pond) were highly infected with metacercariae of avian trematode, i.e. C. orientolis, H. nipponicus. M. oui,entnlis, E. jcponicw and Diplostonum sp., and 4 species of fish. P. parvc, C. breuiccudn, C. eigenmnnni and A. asmussi, were infected with metacaecariae of C. sinensis.

The conclusion of this research after analyzing and interpreting the landscape structure and meaning of Yeongsajeongpalkyung (永思亭八景) that appears in Yeongsajeongpalyeongsi(永思亭八詠詩) of Cheonggye(靑溪) Yang, Dae-bak(梁大樸, 1544~1592) and through document studies, poetry and painting analysis and interpretation, and site investigation, is as follows. Yeongsajeong and its nearby lands are the area of "Yeongsa", where the builder, Ahn, Jeon(安?, 1518~1571) worshipped towards the grave of ancestors, and Yeongsajeongpalkyung oversees a family burial ground in Namwon, centering around Yeongsajeong such as Yocheon, Geumseokgyo and Cheonggyedong, and Sunjagang River and Mountain Jiri, which are the foot hold and key points of advantageous scenic views in Namwon. Yeongsajeongpalkyung, unlike general Jeongjapalkyung, shows a panoramic bird's-eye structure overseeing the landscape and scenery of the Yocheon area and Sunjagang River, in addition to Yeongsajeong, while show in a transition of location, a multi-view structure and time. The trace of visual unity with Sosangpalkyung of China can be seen in many places in Yeongsajeongpalkyung, which seems to be a transitional feature of composing poems regarding Palgyeong during the mid-Joseon dynasty, which pursues harmony with the local landscape of the Namwon area. The 'Changsongchwijuk(蒼松翠竹)' appearing in each of the first and second scenic views of Palgyeong and Yeongsajeongpalyeong can be understood as an incarnation of Yang, Dae-bak, the author of Palyeongsi or Ahn, Jeon, the builder of Yeongsajeong. On the other hand, as a result of interpreting the yin-yang features of poetic diction and picture elements appearing in the subtitle of Yeongsajeongpalyeong, Palyeongsi seems mostly full of yin-like elements and Palgyeongdo. Moreover, as a result of comparing and analyzing the acts expressed in and acts described in Yeongsajeongpalyeong, based on the fact that the reis almost no common ground between the two media except for Soongangmowoo, the third scenic view, the formal similarity between the two media can be acknowledged, however, it is difficult to discover any substantive 'integrity of poetry and painting'.

A case of systemic cryptococcosis developed in 4 year old boy was described and illustrated by light and electron microscope. Light microscopically, the upper dermis of the skin showed chronic nonspecific inflammation with numerous spherical spores surrounded by a clear halo created by the wide gelatinous capsule. Ultrastructurally, the C. neoformans showed the wide capsule containing microfibrils that appeared to radiate from the cell wall and to coil and interwine in various directions. The cell was uninucleate with a single nucleolus. Along the inner nuclear envelope, numerous small vesicles were present. In addition, C. neoformans presented membranous organelles derived from the plasma membrane and comparable to bacterial mesosomes.

In this paper, we propose a system which can perceive status of semiconductor equipment and evaluate its performance. The proposed system acquires the information such acceleration, pressure, temperature and gas sensors in the surrounding semiconductor equipment. After acquiring information, it is sent to server through multi hop transmission. The transmitted data generates 3 steps alarm using context-aware algorithm of unit or multiple event. From the experiment's result of the proposed system, we confirm that the reliability and efficiency of information is more improved about 80% than a system that doesn't use context-aware algorithm. Moreover, this system can be effective status monitoring of semiconductor equipment because lots of client nodes acquire surrounding information.

이 연구는 필자가 2007년 하반기부터 1년간 필리핀에 머물면서, 여성들의 국제결혼에 관해 실시한 연구결과의 일부이다. 이미 한국에서 결혼생활을 하고 있는 외국인여성을 대상으로 한 국내연구와는 달리, 이 연구는 출국준비 중인 필리핀신부들을 대상으로 심층면접을 실시하고 있다. 특히 면접대상자가 일상적으로 사용하는 언어를 이용하고, 시집식구들을 의식할 필요 없는 자유로운 분위기에서 면접이 이루어졌다는 점, 그리고 출국이전의 상황과 심경을 알아보았다는 점 등은 이 연구가 가진 장점이다. 또한 한국으로 들어오게 된 과정을 역추적 하는 방식이 아니라, 결혼, 국내외배우자선택, 특정국적의 배우자선택 과정을 여성 개인의 시각에서 서술토록 한 것도 기존의 연구와 다른 점이다. 연구결과, 필리핀여성의 국제결혼은 미국, 캐나다, 일본 등을비롯해 다양한 국적의 배우자와 이루어지고 있으며, 한국은 그 중의 하나에 지나지 않음을 알 수 있다. 한편, 한국인 남편은 국제결혼알선업체를 통해 만나는 사례가 다수이지만, 한국에 취업이나 시집을 간 친지를 통해 만나는 경우, 취업이나 휴양을 위해 필리핀에 남편이 방문한 동안 만나는 경우, 온라인 교제싸이트를 통해 만나는 경우 등 만남의 경로가 다양함을 알 수 있다. 또한 만남의 경로에 따라 서로 다른 결혼관과 가족관이 발견된다. 이 연구의 결과들에 비추어, 국제이주노동에서 논의되는 이론들의 일부 요소들이 국제결혼현상에서도 어느 정도 설명력을 가진다고 판단된다. 이와 동시에 국가간 방문기회와 인터넷교제기회의 증가라는 전지구화 현상 또한 국제결혼의 또 다른 일면을 파악하는데 주요한 요소가 될 것으로 보인다.

ln competitive electricity market, useful technique would be required to calculate settlement amount for electric power traded between market participants and KPX since a number of market partici-pants would appear and trade electric power. Especially calculation of constrained on/off compensation amount can be complicated, and needs to be understood clearly by market participants to avoid unnecessary disputes. This paper presents a technique to settle more easily constrained on/off compensation amount using surplus function. In this technique, a surplus is calculated by each dispatched values and then the compen-sation amount is calculated by the difference of each surpluses. By doing this, settlement amount can be cal-culated by summing the trading amount and the compensation amount.

Outliers adversely affect model identification, parameter estimation, and forecast in time series data. In particular, when outliers consist of a patch of additive outliers, the current outlier detection procedures suffer from the masking and swamping effects which make them inefficient. In this paper, we propose new outlier detection procedure based on high breakdown estimators, called as the dual robust filtering. Empirical and simulation studies in the autoregressive model with orders p show that the proposed procedure is effective.

신경성장인자 수용체(nerve growth factor receptor, HGFr)의 소재를 휜쥐 전뇌 기저부 핵들의 신경세포와 그 세포내 소기 관에서 연역세포화학적 방법으로 관찰하였다. NGFr에 면역반응을 보이는 신경세포들은 내측중격, 수직 및 수평대각선 브로카대, 거대세포 시삭전핵 그리고 Meynert 기저핵에는 다수 미상핵-피각과 복부담창구에는 소수 관찰 되었다 NGFr에 면역반응을 보이는 신경세포들은 형태학적으로 3가지 형 즉, 1) 난형(또는 원형). 2) 방추형, 3) 삼각형(또는 다각형)으로 구분되었다 내측중격은 주로 난형의 세포로 구성되었으며(91.2%), 수직 및 수평대각선 브로카대, 거대세포 시삭전핵 및 Meynert 기저 핵에는 난형의 세포가 높은 율로 구성되었으나, 방추형과 삼각형 세포들도 내측중격에서보다는 많았다 특히 복부담창구에는 다른 핵들에 비하여 방추형세포(25%)들이 높은 출현율을 보였다 일반적으로 이들 세포의 크기는 삼각형세포가 제일 컸으며, 방추형세포가 그 다음, 그리고 난형 세포가 제일 작았다 전자현미경적 관찰에서 0.05% triton X-100을 처리한 조직중 Meynert 기저핵을 관찰한 결과. Golgi체, multivesicular body 및 소포체들이 N6Fr에 면역반응을 보였으며. trion X-100을 처리하지 않은 조직에서는 단지 수평대각선 브로카대의 신경세포 원형질 막에서만 약한 면역반응을 보였다 위의 결과로 미루어 NGFr은 조연소포체에서 합성되어. Golgi체에서 농축되고, multivesicular body를 통하여 원형질막에 위치하게 되며, 원형질막에서 NGFr은 외래성의 NGF와 복합체를 형성한후, 궁극적으로는 Iysosome의 형태로 세포체 안으로 들어 가는 것으로 추정된다.

This paper described adaptive ANC (Active Noise Control) systems for noise canacelling in multiple inputs and multiple outputs channel. Until this time, it was reported that the study of AMC for the multiple inputs and the multiple outputs had no correlation between input signals of adaptive filters. In fact, it is difficult independently to check the noise source signals and insufficient about this study. In this paper we proposed to use the adaptive filter for eliminating the correlation between input signals. The simulation results showed that the convergence rate improved about two times with this filter than that one without this filter at the rate $b_{12}=0.95$.

Purpose: This study was conducted to examine the individual and community level factors associated with physical activity and to identify its relative effects using a multilevel analysis among Korean adults in certain counties. Methods: A cross-sectional data of 39,547 adults (age range of 19~64 years) living in 82 counties from the 2013 Korean Community Health Survey (KCHS) was analyzed. Individual and social correlates from KCHS and physical environmental data from the Korean Statistical Information Service were collected. A multilevel logistic regression was performed using Stata 10.0 IC. Results: Multilevel analyses showed that the effect of social and physical environmental on engaging in moderate or vigorous physical activity (MVPA) was significant in comparison to the influence of individual correlates. The individual factors that were associated with participating in MVPA included gender, marital status, education, job, and household income. In the community level, social environmental factors associated with engagement in MVPA were higher satisfaction with healthcare service (OR=3.410, 95% CI=1.109~11.269), a high level of social support (OR=5.920, 95% CI=1.459~22.657) and social network (OR=1.025, 95% CI= 1.017~1.032). Conclusion: To promote moderate or vigorous physical activity in Korean adults in some counties, social environmental factors should be considered along with individual correlates.
