The major characteristics of the developed corn hybrids were compared at each different planting time; 1st time(April 28) and 2nd time(August 20), respectively. Among traits surveyed, stem height showed highly at 1st time than 2nd, while ear height, stem diameter and ear length were similar at two times. Sugar content of the used hybrids showed highly at 2nd planting time than 1st. Pericarp thickness was also high at 2nd planting time. Especially, among hybrids CNU99 was the highest in stem height and ear length, CNU11 and CNU56 were high in sugar content, and CNU51 and CNU124 were thiner than other hybrids in pericarp thickness. Accordingly, these hybrids will be planted and recognized in 2nd yield trial for superior corn hybrid selection.

본 논문에서는 ad hoc network에서 클러스터를 기반으로 노드들의 인증을 통한 안전한 데이터 전송 방법을 제안하였다. 클러스터를 관리하는 클러스터 헤드 노드는 클러스터가 형성될 때 멤버 노드들의 이웃 노드들에 대한 신뢰 정보를 받는다. 클러스터 헤드는 이러한 신뢰 정보와 자신의 정보를 조합하여 보다 정확하고 효율적으로 다른 노드를 평가한다. 이렇게 함으로써 네트워크에 새롭게 참여하는 노드에 대해서도 보다 정확한 인증을 수행할 수 있게 된다. 그리고 무선망의 제한된 대역폭을 고려하여 네트워크 상의 제어 패킷의 양을 줄여 데이터 전송의 효율성을 증가시키기 위해 제한된 broadcast 메커니즘을 이용하였다. 실험을 통해 제안한 방법의 효율성을 확인하기 위해 클러스터 헤드의 수, 경로 길이, 그리고 제어 패킷의 양을 측정하였다.

The department stores in Korea, which represent the existing distribution industries, face a structural turning point. Especially, such environmental changes seriously threaten the department stores in Kwangju. In addition the big department stores and discount stores in Seoul opened or will open their branch shops in Kwangju, and so the keen competition of local industries is expected. If the big department stores with rich fund and advanced management know-how establish their branch shops in local areas, the status of existing local department stores will lowered as much. Therefore, the local department stores need to analyze and examine all conditions of competitors as well as their own current conditions and levels. The purpose of this study is to investigate how the department stores have been recognized by consumers as a pre-stage for facing the environmental changes, to schematize the consumer's preference for department stores in Kwangju spatially and to connect the properties which compose the image of a department store based on the perceptual position and competitive relations which the consumers recognize for four department stores (Garden, Songwon, Shinsegae and Funny) in Kwangju as research objects, and then to find the strength and weakness of a department store. This study uses PC-MDS program to grasp the competitive relations among department stores and make a positioning map. As a result of examining the matrix data about customers' responses for the degree of similarity of four department stores by each couple with a KYST analysis, Shinsegae and Songwon are superior to Garden and Funny. In addition, in order to interpret the axis (dimension) of scheme from KYST, this study abstracts 12 properties which compose the images of department stores and performs a PROFIT analysis, and furthermore consumers are asked to choose their preferred department stores in three conditions (gift purchase, dress purchase, and A/S and disposal of returned goods) and then this study conducts PREFMAP analysis. The result suggests that the consumers recognize Shinsegae and Songwon as the best department stores. Finally, the results of this study show the perceptual position of four department stores in Kwangju schematically and propose the position of the most ideal department stores, and this study suggests the direction of strategy for positioning of department stores in Kwangju, as a pre-stage to understand how the department stores are recognized by consumers, in order to cope with the environmental changes.

This thesis makes use of kinematic and kinetic method to analyze walking movement with a 16 mm high speed camera, a force platform, and EMG system. The subjects for the research were 6 high school students, 2 of whom were skilled race walkers, 2 skilled runners, and 2 unskilled average students in each sex. The mechanism of walking locomotive pattern was measured by a motion analyses are as follows: 1) Too much flexing of the ankle joint can cause damage as it brings about the dispersion of power energy and forces too much burden on the ankle. 2) The analysis of the ground reaction force shows that the M-shaped curve of the vertical G.R.F. was almost the same as that of the previous studies. The skilled race walkers and runner recorded the shorter supporting time, 0.62 second, in comparison with 0.72 second recorded by average students. 3) The anteroposterior G.R.F. in walking is considered most desirable when it minimizes the breaking power at touch-down, but maximizes the driving force at take-off. 4) From EMG analysis, it is known that the activity voltage of vastus medialis is very high while walking and higher in male students than in female students. This seems to result from well-developed muscles of the male students. 5) The walker has the most correct walking locomotion when he moves his hip joint or knee joint gently with his body upright and his eyes kept ahead.

신성웅,임명호,현태영,성양숙,조수철 대한소아청소년정신의학회 2001 소아청소년정신의학 Vol.12 No.1

뚜렛씨 장애는 근육틱과 음성틱이 만성적으로 지속되는 질환이다. 만성 틱장애는 근육틱 혹은 음성틱 중 하나만 지속적으로 나타나는 질환이다. 본 연구에서는 1998년 4월 1일부터 1999년 4월 1일까지 서울대학교병원 소아정신과 병동에 입원한 만성 틱 장애 아동과 뚜렛씨 장애 아동의 임상적 특징을 조사하고 두 질환 사이의 관계를 비교하고자 시행되었다. 이들의 특성을 확인하기 위해 대조군으로 학습장애 환자를 선정하였다. 조사 결과는 다음과 같다. 첫째, 만성 틱장애(n=13)와 뚜렛씨 장애 환자(n=29)의 평균 발병연령은 각각7.3±2.5, 7.2±2.2.세, 입원시 연령은 평균 11.7±2.7, 11.5±2.6세, 입원기간은 5.7±5.4, 11.0±8.7주였고두 군 사이에 의미 있는 차이는 없었다. 학습장애의 경우 발병연령(4.2±1.9세)이 두 장애보다 빠르고 의료기관을 찾는 시기(9.8±3.2세)도 빨랐다. 출생 계절은 틱장애 환자들에서 6월에서 9월 사이가 가장 적었지만 의미 있는 차이는 없었다. 남녀의 성비율은 각각 10 : 3, 26 : 3, 11 : 5였고 의미 있는 차이는 보이지 않았다. 환자가 출생할 때의 아버지와 어머니 연령은 세 군 모두 차이가 없었다. 둘째, 정신과적 가족력이 있는 경우도 세 군 사이에 차이가 없었고 각각 24.1%, 46.2%, 56.3%였다. 발병전 유발 요인이 확인된 경우는 만성틱장애와 뚜렛씨 장애에서 11.1%와 35.7%로서 의리 있는 차이를 보이지는 않았지만 학습장애(56.3%)에 비해서는 적었다. 셋째, 만성 틱장애와 뚜렛씨 장애, 그리고 학습장애 환자의 지능지수는 각각 언어성 지능 92.3±10.7, 94.7±14.9, 94.3±13.8이었고, 동작성 지능은 93.0±20.5, 97.5±13.0, 95.0±16.9이었으며, 전체 지능은 91.9±20.1, 95.8±14.5, 93.9±15.1로서 세 군 사이에 의미 있는 차이가 없었다. 기질적 뇌장애 소견은 CT/MRI등에서 0%, 27.3%, 6.3%, 뇌파 이상은 8.3%, 17.2%, 12.5%에서 나타났고 차이는 발견하지 못하였다. 넷째, 항도파민 약물에 대한 반응은 만성 틱장애와 뚜렛씨 장애 환자에서 각각 84.6%, 77.0%가 부분관해를 보였고 완전 관해된 경우는 한 명도 없었으며 두 군 사이에 차이가 없었다. 다섯째, 공동 유병현황을 조사한 결과 주의력결핍 · 과잉운동장애가 학습장애에서 의리 있게 많은 것을 제외하고는 세 군 사이에 통계적으로 의미 있는 차이를 보이지 않았다. 조사 결과 입원한 환자의 경우 만성 틱장애와 뚜렛씨 장애를 가진 환자들은 임상적으로 학습장애를 가진 환자와 많은 부분에서 파이를 보였으나 만성 틱장애와 뚜렛씨 장애를 구분해야 하는 근거를 찾지 못하였다. 중심 단어 : 뚜렛씨 장애 · 틱장애 · 진단 분류 ㆍ 임상적 특성. Tourette's disorder is a disease which manifests one or more motor tics and vocal tics for more than a year. Chronic motor tic or vocal tic disorders are characterized by only one kind of tics for more than a year. We intended to investigate the clinical characteristics of the patients with chronic motor tic disorders or Tourette's disorders who had admitted from May 1, 1998 to May 1, 1999 to Seoul National University Hospital Child and Adolescent Psychiatry ward. In addition, we compared the clinical characteristics of the patients in order to elucidate the relationship between the two disorders. The patients with learning disabilities were selected as controls. There was no statistically significant difference between the onsets of the patients with chronic motor tic disorders(n=13, 7.3±2.5 years) , and Tourette's disorder(n=39, 7.2±2.2 years), but with learning disability (4.2±1.9 years). Also, the patients with chronic motor tic disorder and Tourette's disorder showed similar age at admission (11.7±2.7 versus 11.5±2.6 years), duration of admission (5.7±5.4 versus 11.0±8.7 weeks), mothers' ages at child birth(27.3±2.9 versus 28.3 ±6.7 years old), and fathers' age at child birth (32.2±3.2 versus 33.3±5.2 years old). We observed that those who had learning disabilities were alike in those aspects, except for age at visit to clinic (9.8±3.2 years old). Family history of psychiatric illnesses (24.1% versus 46.2%), recognized precipitating factors (11.1% versus 35.7%) and response to pharmacological treatments (77.8% versus 76.9%) of the patients with chronic motor tic disorders and Tourette's disorders were observed and no differences were found. Comorbid patterns of diseases were noted. Intrafamilial conflicts were more common in the patients with learning disabilities than those with chronic tic disorders or Tourette's disorders. Precipitating factors were observed more frequent in chronic tic disorder and Tourette's disorder than learning disability. Neurocognitive profiles were investigated, and verbal IQs of the patients with chronic motor tic disorder, Tourette's disorder and learning disability were 92.3±10.7, 94.7±14.9, 94.3±13.8, performance IQs 93.0±20.5, 97.5±13.0, 95.0±16.9 and full-scale IQs 91.9±20.1, 95.8±14.5, 93.9±15.1, respectively, which were found to be not significantly different. No difference was found in structural neurological abnormalities and EEG profiles. The patients with learning disabilities showed more common Bender-Gestalt test abnormalities. In conclusion, we have not found any affirmative clues for the division of chronic motor tic disorder and Tourette's disorder in clinical perspective. KEY WORDS : Tourette's disorder ㆍ Tic disorder ㆍ Classification ㆍ Clinical study.

This study was designed to investigate the problem of the existing Running Standard Last for the Male adult and to suggest some useful information for the better design development and construction of running shoes last. The subjects for this study are based on 4 male adults who had the running pattern of rearfoot strike with normal feet. 51 separate measurements of four lasts of running shoe with N, R, AD, AS brand were tested using a 3-mentional measurement. Four running shoes and a barefoot were measured using a pressure distribution measurement. The findings of the study were as follows 1) The N running shoes last was larger than those for R, AD and AS the standard in the 8 items. The AS running shoes last was larger than those of N, R, AD last in the 8 items. The R's last was the biggest in short heel girth and long heel girth. The AD's last was the biggest in seat length and firth toe height 2) In the regional peak pressure of the running sheos, the barefoot and brand running shoes showed the biggest pressure distribution in the hallux, There were the slightest pressure in the medial midfoot and lateral midfoot. 3) The instance of regional peak pressure, the barefoot and the running shoes showed earlier peak pressure for the lateral heel. It was barely possible to measure pressure distribution in medial midfoot. 4) In the light of time percentage of peak pressure distribution measurement in each mask, N running shoes showed the longest time in medial heel, lateral heel, medial midfoot, lateral metatarsal and lateal toes, AD running shoes showed the longest in first metatarsal, second metatarsal and hallux, R running, the longest in second toes. 5) In the maximum force for pressure distribution, barefeet showed the biggest pressure distribution in second metatarsal and R, AD running shoes the biggest in first metatarsal, respectively. 6) In the time of peak pressure distribution measurement, barefeet quickly showed peak pressure distribution in the lateral midfoot. Simultaneously, N. R, AD and AS's running shoes showed peak pressure distribution with barefeet. 7) In the characteristic of the new last's model, bottom length resulted in 276.00mm, stick length 283.29mm, 70% ball mirth 255.12mm, bottom width 91.21mm, toe thickness 30.00mm.

The purpose of this study is to examine life styles of male and female students, who are from middle and high schools under the Pusan Educational Office, for health perception by using Pender's health promotion model as a theoretical basis. For the purpose, factors of health perception were selected as influencing life styles for health promotion in order to determine the relationship between the perception and the life styles. The results of the study can be summarized as follows; In an analysis of the overall status of health perception, significant differences were not found between middle and high school students, and between male and female students. specifically, however, middle school students showed more positiveness about self-confidence in health condition, resistance for disease prevention, health status comparison and self-confidence in future health than high school ones, but found themselves about their tendency of frequent sickness and anxiety about health. Further, male students responded more positively to practice for disease prevention, interest in health and uncertainty about future health than female ones and more negatively to tendency of frequent sickness. Consequently, it is necessary for middle schools to perform a basic and systemic health education to ensure that their students establish fundamentals for health throughout the whole life. For high school students, practical programs of health education should be strengthened. The fact that male students have more desirable life styles for health perception and health promotion than female ones suggests that physical classes or health education programs should be prepared to attract female students more.

The objective of this investigation was to obtain the necessary information for the increment of the cultivated land utilization and the establishment of more reasonable multiple cropping system in paddy and upland around Kyungpook Province. For the analysis of the obtained data we used the fixed model employing the arbitrary classification of the regions in sampling. The results of this investigation were summarized as follows: 1. In the acreage per farm household, it was obvious that the farm household in the suburban and truck farming regions has more upland acreage than paddy. On the contrary, there was the exactly reverse trend in the intermediate and fall-behind regions. 2. The old Japonica rice varieties were utilized in the suburban and truck farming regions comparing with the intermediate and fall-behind region using the new Indica-Japonica rice varieties. This tendency in the suburban and truck farming regions was closely associated with the cultivation, especially the harvesting date, of the post-crop after rice. Therefore, it was highly recommandable to develop new high yielding rice variety for the late transplanting in these regions. 3. The rate of the paddy utilization was the highest in the suburban region and was very low in the intermediate and fall-behind region. On the whole regions, the larger paddy owner utilized the lesser in its rate. 4. Barley was cultivated most widely as post-corp after rice in the sampling area. Vegetables in the suburban regions and water melon in Seongju and garlic in the Euiseong were main post-crops in the paddy multiple cropping systems. 5. The rate of the upland utilization was the highest in the suburban regions and was very low in the truck farming region because red pepper and tobacco production region employing only one crop per year. 6. In the double cropping system on the upland, barley and soybean combination was most in the cultivated acreage. The main double cropping system available in the suburban region was fruit vegetables and Chinese cabbage combination. 7. For the increment of the paddy and upland utilization, and of the farm income through the establishment of the reasonable cropping system, it will be desirable to study various possible multiple cropping systems on the experimental basis and the introduction of new crops and varieties may be considered for the incentive of production and return.
