        이동 에이전트의 최적 이주 비용을 위한 플랫폼 설계

        김완성,복경수,신재룡,유재수 한국정보통신학회 2004 한국정보통신학회논문지 Vol.8 No.1

        네트워크의 발달과 다양한 서비스의 요구에 따라 새로운 소프트웨어의 패러다임에 대한 요구가 증가되고 있다. 이와 함께 이동 에이전트에 대한 많은 연구가 진행 중이다. 이동 에이전트의 수행에 있어 이주비용은 이동 에이전트의 성능에 많은 영향을 미친다. 본 논문에서 이동에이전트의 이주비용을 최적화하기 위한 기법을 제안한다. 제안하는 이주기법의 특징은 다음과 같다. 첫째, 네트워크 상태 및 플랫폼 상태변화에 적절하게 대응할 수 있는 동적 경로를 생성하여 에이전트 수행 효율을 높인다. 둘째, 수행할 코드를 프리패칭하여 이동 데이터 양을 줄이고, 필요한 에이전트를 미리 인스턴스시켜 수행 시간을 단축한다. 셋째, 체크포인트 기법을 사용하여 에이전트 수행 중에 에러가 발생할지라도 에이전트는 재 수행을 하지 않고 에러 이전의 상태로 복구하는 방법을 사용하여 수행 효율을 높인다. 또한, 시뮬레이션을 통해 기존방법과 제안하는 방법을 비교 평가한다. 시뮬레이션 결과분석을 통해 이주관점에서 제안한 방법들이 기존방법들에 비해 성능이 매우 향상됨을 보인다. A new software paradigm is required on the development of network and various service requirements. With this, many studies on a mobile agent have been made. For the execution of the mobile agent, migration is the most important factor that influences the performance of the mobile agent. In this paper we propose the method that leads to high migration efficiency in order to improve the performance. The features of our migration technique are as follows. First, the migration technique creates the dynamic itinerary that appropriately copes with the network conditions and the platform changes to improve the agent execution efficiency. Second, it perfecters an executed code to reduce the amount of the mobile data and reduces the execution time by instantiating the agent in advance. Third, it improves the execution efficiency by using the checkpoint-based recovery method that does not execute the agent again and recovers the process states even though the errors take place. Though the simulation we compare the proposed method with the existing methods. The simulation result shows that the proposed method outperform the existing methods in terms of migration.

        향가 <찬기파랑가>, 윤선도 <오우가>, 박목월 <나그네>의 달의 의미 고찰

        김완성 한국국어교육학회 2009 새국어교육 Vol.0 No.81

        This study looked how the meanings of the moon appeared in <Changiparangga>, a piece of Hyangga, a genre of old Korean folk songs, <Ouga> by Yunseondo, a piece of Sijo, old Korean verses and <Nageune> By Bangmogwol, a contemporary poem, are unfolded differently according to the times, genres and the religions of each writer. Literature reviews reveals that some researchers considered the moon in the <Changiparangga> as Giparang, the protagonist in the poem while others saw it as a symbol of the Buddha or a Buddhist saint. The moon in the <Ouga> has been viewed as a natural object or the object of the nature worship as a means of human obligations. The moon in the <Naguene> was interpreted sometimes as a natural object but sometimes as a poetic self or the prototype of the universal formation. The findings of this study are as such:<Changiparangga>, written by Chungdamsa, a Buddhist monk, is basically a song based on Buddhism and regarded the moon as a natural object. The moon depicted in <Ouga>, written by Yunseondo, a member of the gentry, was an object engrafted human obligations into. Bangmogwol, who was a Christian, saw the moon in his poem <Nageune> a symbol of a traveler. 본 연구는 삼국시대 신라의 향가인 〈찬기파랑가〉, 조선시대 시조인 윤선도의 〈오우가〉, 현대시인 박목월의 〈나그네〉에서 달은 시대별, 장르별, 작가의 종교별로 각각 우리에게 어떤 의미로 이해되는지 고찰해 보았다. 고구해 본 결과 학자에 따라, 〈찬기파랑가〉에서 달은 기파랑을 상징한다고 하고 , 또는 석존과 보살의 상징이라고도 했다. 〈오우가〉에서는 달의 의미를 사람의 도리를 수단으로 삼아 자연을 예찬하는 목적물로 보기도 하고, 자연물로 해석하는 논자도 있었다. 〈나그네〉의 달은 자연물의 달로 보기도 하고, 시적자아로 달을 해석하기도 했다. 혹자는 우주적 생성의 원형으로 보기도 했다. 필자는 승려인 충담사가 지은 향가인 〈찬기파랑가〉는 불교사상을 기저로 한 노래로서 달의 의미를 자연물로 보았고, 조선조 사대부인 윤선도의 시조〈오우가〉의 달의 의미는 자연물에 인간의 도리를 접목한 대상으로 보았으며, 기독교 신자인 현대시인 박목월의 〈나그네〉에서의 달의 의미는 나그네의 표상으로 해석했다.

      • 복부 초음파 검사 보편화 시대의 소아 장중첩증의 임상적 고찰 - 소장형과 대장형의 비교 -

        김완성,정진호,이종훈,박재균,문현종,신혁재,이종인,Kim, Wan-Sung,Jeong, Jin-Ho,Lee, Jong-Hoon,Park, Jae-Kun,Moon, Hyoun-Jong,Shin, Hyuk-Jai,Lee, Jong-In 대한소아외과학회 2011 소아외과 Vol.17 No.1

        We analyzed the clinical characteristics and outcome of ileocecal and small bowel intussusceptions (ICI and SBI) in the pediatric patients. From August 2003 to July 2010, 144 children with intussusception were included in this study. We retrospectively reviewed the clinical records and Imaging study findings. A total of 86 children with ICI and 58 children with SBI were diagnosed. Children with SBI were older than ICI ($36.6{\pm}24.6$ months vs. $24.2{\pm}21.6$ months, p=0.002). Typical symptoms such as irritability, abdominal mass, bloody stool were more frequent in ICI than SBI (p<0.05) patients. In the ICI group, intussusceptums were reduced with air reduction (84.5%), surgery (17.4%), and spontaneity (1.2%). All patients in the SBI group were reduced spontaneously. SBI occurred in older age and was reduced spontaneously more frequently than ICI. Conservative management with close observation with follow-up by ultrasonography is recommended for SBI.

        서울시 보건소 물리치료사들의 지역사회중심재활에 대한 인식

        찬문,완성,배성일,Kim, Chan-Mun,Hong, Wan-Sung,Bae, Sung-Il 대한물리치료과학회 1998 대한물리치료과학회지 Vol.5 No.1

        To survey the recognition of Community Based Rehabilitation(CBR) by Public Health Center(PHC) Physical Therapists in Seoul Province. This study analysed general characteristic of Physical Therapists and cognition, participation, education, problems and requirements for CBR. The subjects of this study were 31 therapists who work at PHC in Seoul Province and Seoul City Childerns Municipal Hospital. Data was collected for 18 days from April 13 to 31, 1998 and results computed from 25 responses. First, Female therapists outnumber males. The age category 30 to 35 old represented 44.0% of the total number studied. 48.0% of therapists had worked more than 7 years and therapists usually 84.0% worked from 3 to 4 years at the PHC. Junior colleage graduates were 72.0%, and respondents with family responsibility were 52.0%. Second, Recently pain control and therapeutic exercises has become the major requirement of patients at PHC(56.0%). If the offered expanded services, a rehabilitation programe at PHC(36.0%) was highly. When asked about a working guide book, nobody had one. Third, 64.0% of therapists were aware of the present level of CBR, 28.0% of them had gotten an information from newspaper and mass media. Fourth, For CBR, 72.0% had positive ideas in which they could participate. 56.0% wished to compose a team of various rehabilitation specialists. 52.0% wished for the meeting day to be flexible and 64.0% desired to meet once or twice a week. Fifth, Almost all(92.0%) desired more educational opportunity about CBR. Example, once or twice a year(48.0%) and training period of 4 to 7 day(44.0%). They wanted to learn theory and parctice together(88.0%) and 48.0% wanted national mutirehabilitation center as a educational managing organization. Sixth, The most important requirement for accomplishing CBR by Physical Therapists was job security and adequate number of therapists(48.0%). Required number of physical therapists in the PHC was 3(52.0%). The cooperative agency should be the distict govement(32.0%) and community welfare center of the disabled persons(32.0%). Factors inhibiting the execution of CBR were lack of physical therapists(56.0%), and equipments for pain control and for therapeutic exercises(68.0%).

      • Ontogeny of Gonadotropin-releasing Hormone and Tyrosine Hydroxylase Neuronal Systems in Rat by Immunohistochemistry and In Situ Hybridization

        KIM, MYEONG OK,KIM, CHUNG JUNG,BAE, SANG DO,PARK, JONG MOON,LEE, BONG HEE,CHOI, WAN SUNG 경상대학교 유전공학연구소 1991 遺傳工學硏究所報 Vol.10 No.-

        The ontogeny of gonadotropin-releasing hormone(GnRH) and tyrosine htdroylase(TH) neuronal system in rat was investigated by means of immunohistochemistry(IHC) and in situ hybridization(ISH). GnRH system which contains irGnRH first appeared in the nasal region at embryonic day (E) 11.5 and migrated caudally into the forebrain with increasing the frtal age. TH system was first detected at (E)11.5 in the undifferentiated mesenchymal cells and then found in the brain at the following developmental periods. Development and distribution of GnRH mRNA and TH mRNA containing cell bodies by ISH was well coincided with the data of ontogeny obtained by IHC. These data described above makes us to suggest that GnRH and TH containing cells are originally developed in the peripheral nervous system amd migrated and then, detected within the brain with increasing the fetal age.

      • 干拓地防湖堤의 높이와 그 斷面에 關한 硏究

        姜信業,金完成,安秉基 忠南大學校 1969 論文集 Vol.8 No.-

        It is needless to emphasize that Sea-walling is most important in reclamations by drainage. The data for the present study are those gathered by surveying the coastal sea features or by studying the features surveyed by the hydrographical department of ministry of transportation since there are differences in geographical features in depth, coastal windings, number of islets of the seas, eastern, western, and southern that Surround Korea. In deciding the planned tidal level, the following two ways are available if we have a ling term of tidal level record for the spot concerned, the one being the way Solely to depend on the tidal level record, the other to get the planned tidal range by Separating the range from the tidal level record. It is to admitted that even under the same seastorm, there is a wide difference between the tidal ranges in accordance with whether the biggest declination arises in high water or in low water since the term to the tidal level records is no longer than 50 to 60 years at most. Therefore the decision of the planed tidal level for the short term of tidal level records was made on the supposition that the biggest declination always occurs under high water. And the planned tidal level is to be gotten by adding the declination of the planned tidal level to the high tidal level. If the term of the tidal level is to be gotten by adding the declination of the planned tidal level to the high tidal level. If the term of the tidal level record was short, the planned declination were fixed by inferring the declination frequency, separating the declination of the tidal level and considering its relation with the meteorological data. As for the districts without tidal level records, inferences were done by some similar records by the tide station. Concerning the wind velocity, I looked through all of the data surveyed by the meteorological observatory,'vatory' examining and comparing the height and the biggest tidal level of the seawalls in the main dried lands Korea has constructed so far
