To establish an indoor-rearing system for the Large Copper butterfly, Lycaena dispar and the Small Copper butterfly, Lycaena phlaeas, the effect of temperature, photoperiod and host plants on larval development was investigated. The larvae of Lycaena dispar fed on Rumex crispus, whereas the larvae of Lycaena phlaeas ate both Rumex crispus and Rumex acetosa. The duration of the larval period of Lycaena dispar was 13.8 days on R. crispus and that, of Lycaena phlaeas was 15.9 days and 15.2 days on R. acetosa and R. crispus respectively. Laboratory experiments show that the Large Copper larvae are able to feed on other Rumex species without harming their overall survival and can utilize these alternative host plants at least as efficiently as their natural host plant. This result suggests that plant chemistry is not responsible for their lack of utilization of the alternative host plants in the wild. Host plant choice by ovipositing females was measured with the two alternative hosts. Lycaena dispar preferred R. crispus to R. acetosa, wheareas Lycaena phlaeas preferred R. acetosa to R. crispus. Temperature has been proposed as an important determinant of developmental rate, lifespan and mortality in invertebrates. As temperature increased, length of the developmental period gradually decreased. The developmental period of the Large Copper larvae was 11.0 days and 28.5 days at 30oC and 17.5oC, respectively.

It is a well known fact that enhanced coagulation can effectively eliminate natural organic matter known as precursor of disinfection by-products. In the study, effect of the enhanced coagulation was investigated by isotherm, kinetic and molecular weight distribution on activated carbon adsorption. The strongly adsorbable fraction was not preferably removed by enhanced coagulation. This conclusion could be drawn by that K value and initial concentration did not show much difference. Therefore, the effect of the enhanced coagulation on isotherm was to reduce the initial concentration over the each adsorbable fraction. When the enhanced coagulation was adapted for pretreatment for activated carbon adsorption the operation period could be extended to 3 to 4 times. The dominant molecular weight (MW) fraction was less than 1,000 for all samples. In conventional coagulation MW bigger than 10,000 was effectively removed. In the enhanced coagulation MW smaller than 1,000 was preferably removed. It was observed that the strongly adsorbable fraction had very strong relationship with the MW less than 3,000.

골격성 Ⅲ급 부정교합자의 두개안면골격형태가 하악이부형태와 하악전치의 위치에 미치는 영향을 알아보고자 연구를 시행하였다. 전후방적인 악골부조화가 나타나지 않고 교정치료의 경험이 없는 만 20세 이상의 성인남녀(정상군)와, 하악전돌의 악골부조화를 보이며 교정치료의 경험이 없는 만 20세 이상의 성인남녀(하악전돌군)를 비교하여, 두개안면골격형태에 따른 하악이부형태와 하악전치의 위치에 관하여 다음과 같은 결론을 얻었다. 1. 두개안면골격형태의 비교에서 하악에 관련된 ∠SN-Mn, ∠FMA, ∠Pal-Mn, ∠LFH은 하악전돌군이 정상군에 비하여 크게 나타났지만, (p<0.05) 상악에 관련된 항목은 차이를 나타내지 아니하였다(p>0.05). 2. 하악전치를 둘러 싸고 있는 치조돌기는 하악전돌군이 정상군에 비해서 수평적으로 좁고, 수직적으로 긴 형태를 나타내었다(p<0.05). 하악이부의 형태에서도 수평적으로는 하악전돌군이 정상군에 비해서 좁게 나타났으나, 수직적으로는 차이를 나타내지 아니하였다(p>0.05). 3. 하악전돌군의 두개안면골격형태와 이부계측항목과의 상관관계에서 두개저와 하악하연에 기인하는 수직적인 악골부조화가 증가할수록 LaABH, LiACBW, LaACBW, LiABBW, SW, ∠LISA가 감소하는 역상관계를 나타냈지만(p<0.05), 전후반적인 악골부조화와는 별다른 상관관계가 나타나지 않았다(p>0.05). 4. 하악전돌군에서 수직적인 두개안면골격형태를 나타내는 ∠SN-Mn, ∠FMA, ∠Pal_Mn, ∠LFH와 하악이부의 계측항목인 ∠LiACBW. LiaBBW, SW, ∠LISA사이에 높은 상관관계가 존재하여, 수직적인 악골부조화로 하악이부의 형태와 하악전치의 경사도를 예측할 수 있었다(p<0.001). The purpose of this study was to evaluate the morphology of mandibular symphysis and location of lower incisor under the influence of the craniofacial skeleton in skeletal Class III malocclusion. The sample consisted of 132 adults who have severe Class III malocclusion (prognathism group, 33 males and 33 females), and who have normal occlusion (normal group, 33 males and 33 females). They had not received any orthodontic treatment or orthognathic surgery. The lateral cephalograms were evaluated. The results were as follows: 1. Prognathism group were larger than normal group in comparison of facial skeleton (p<0.05) with the exception of ∠FH-Pal, ∠SNA. 2. In the morphology of symphysis, measurements of anteroposterior width(LaABBW, LiABBW, SW) of prognathism group were significantly less than that of normal group(p<0.001). 3. In the correlative analysis between the craniofacial skeleton and symphysis measurements of prognathism group, vertical measurements in relation with cranial base and mandibular plane showed reverse correlationship with anteroposterior with of symphysis(LiACBW, LaACBW, LiABBW, SW)(p<0.05). But, there was not distinct difference between horizontal skeletal measurements and symphysis measurements(p>0.05). 4. The probability by regression test between vertical measurements(∠SN-Mn, ∠FMA, ∠Pal-Mn, ∠LFH) and symphysis measurements(LiACBW, LiABBW, SW, ∠LISA)were very high(p<0.001).

조성제,권용진 한국항공대학교 1999 論文集 Vol.37 No.-

이동로봇에 통시기술을 결합하여 응용하려는 시도는 Tele-Robotics 라는 학문의 한 분야로 이미 국내외적으로 정착되고 있다. 초기에 Tele-Robotics, Tele-Operation기술은 극한작업을 위해서만 사용되었으나, 최근에는 일상생활과 밀접한 다양한 분야로 그 응용분야를 넓혀가고 있다. 본 논문에서는 대화식 무선통신 기능을 가진 이동로봇을 제작하고 그와 통신할 수 있는 호스트 시스템을 구성하여 이동 로봇의 원격 제어, 원거리에서의 지형 탐색, 데이터 수집 기능 등을 구현함으로써 본격적인 원격 탐색 시스템 구축을 위한 기초 연구를 수행하였다. The effort to combine communication technology with a mobile robot and its application has already become a part of study. In the introducing stage, the tele-robotics, tele-operation technology was applied to extremely hard or dangerous work where man cannot reach, however, its application range is becoming wider and wider into various human lifes. In this paper, we designed and implemented a mobile robot and a host system which interact with each other by wireless communication. The robot is remote controlled by the host for remote surveillance and data collection which may be a basic of the remote surveillance system.

목 적 : 본 연구는 수용시설의 노인들에서 인지기능장애와 우울증상의 유병율을 조사하기 위한 것이다. 방 법 : 한국의 한 수용시설인 꽃동네에 거주하는 60세 이상 노인 169명을 대상으로 한국판 Mini-Mental State Examination(MMSE-K). Short Portable Mental State Questionnaire(SPMSQ), 축약판 Geriatric Depression Scale(SGDS). 그리고 the Center for Epidemiologic Studies Depression (CES-D)을 적용하였다. 결 과 : 전체 169명중 153명(남자=72명, 여자=79명, 그리고 누락=2명)이 검사를 완성하였다. 연령의 범위는 60에서 102세였고, 평균연령은 74.17±8.27(남자71.76±8.14. 여자76.14±7.78)세였다. 교육기간의 범위는 무학에서 16년이었고, 평균교육기간은 3.04±3.93(남자 4.13±4.23, 여자 2.01±3.38)년이었다. 인지기능장애의 유병율은 MMSE-K≤23의 기준으로 56.2%, SPMSQ≤6의 기준으로 26.1% 로 평가되었다. 비교적 분명한 인지기능장애의 기준으로 MMSE-K≤19를 적용하였을 경우 유병율은 25.5%로 이는 SPMSQ≤6을 기준으로 하여 얻은 결과와 유사한 수준이었다. 우울증상의 유병율은 SGDS≥10의 기준으로 19%, CES-D≥25의 기준으로 23.5%로 평가되었다. 비교적 가벼운 우울증상까지 선별하기 위하여 SGDS≥8을 기준으로 할 경우 유병율은 39.2%로 이는 CES-D≥20을 기준으로 하여 얻은 결과와 일치하는 수준이었다. MMSE-K와 SPMSQ, SGDS와 CES-D, MMES-K와CES-D, MMES-K와 SGDS, 그리 고·SPMSQ와 SGDS 사이에 의미있는 상관관계가 관찰되었다. 결 론 : 수용시설 노인들에서 인지기능장애와 우울증상의 유병율은 매우 높은 수준이며, 이러한 결과는 수용시설 노인들에 대한 보다 집중적의 의료서비스가 필요함을 시사한다. Objectives : This study was to investigate the prevalence of cognitive impairment and depressive symptomatology among the long-term institutionalized elderly people. Methods : Mini-Mental State Examination-Korean version(MMSE-K), Short Portable Mental State Questionnaire(SPMSQ), Short version of Geriatric Depression Scale(SGDS), and the Center for Epidemiologic Studies Depression(CES-D) were administerd to 169 elderly residents in an institution, 'Got Dong Rae'. Results : One hundred fifty-three(males=72, females=79, and missing=2) completed the entire examination. Age ranged from 60 to 102 years and the mean of age was 74.17±8.27(males 71.76±8.14, females 76.14±7.78) years. Duration of education ranged from 0 to 16 years and the mean of duration of education was 3.04±3.93(males 4.13±4.23, females 2.01±3.38) years. The prevalence of cognitive impairment was estimated as 56.2% by MMSE-K≤23 and 26.1% by SPMSQ≤6. The prevalence of relatively definite cognitive impairment defined by MMSE-K≤19 was 25.5%, which was similar to the result achieved by using SPMSQ≤6. The prevalence of depressive symptomatology was estimated as 19% by SGDS≥10 and 23.5% by CES-D≥25. In the case of using SGDS≥8 as cutoff-point to screen mild as well as severe depressive symptomatology, the prevalence was 39.2%. It was identical to the result achieved by using CES-D≥20. Significant correlations were observed between MMSE-K and SPMSQ, between SGDS and CES-D, between MMSE-K and CES-D, between MMSE-K and SGDS, and between SPMSQ and SGDS. Conclusion : The prevalencies of cognitive impairment and depressive symptomatology were high in institutionalized elderly people. This results suggests that more intensive mental health care is needed for long-term institutionalized elderly people.

스파크 점화기관의 연소에 의한 압력변동에 관한 연구

趙成濟 서라벌대학 1996 논문집 Vol.10 No.-

In a spark ignition engine which has the combustion characteristics of a premixed homogeneous charge and flame propagation, maximum cylinder pressure equal to heat release per cycle during burned period depends upon the rate of heat release and volume change according to the piston motion. The view taken in this study is that combustion analysis process and the pressure variation in combustion chamber with engine variations. The results are as follows. 1. As the degree of mean and standard deviation of all factor according to cycle variation, it is known that combustion becomes unstable as leaner as mixture ratio becomes. 2. The mixtures are the leaner and the spark timing is the retarder, the main combustion period is the longer. 3. The stability of engine combustion and performance is enhanced by advancing spark timing to MBT conditions. 4. The pressure in combustion chamber and the rate of pressure rise is the higher and the time of that is nearing to the TDC, the mixture is the richer.
