A Study on the Coefficient of Permeability in Fine Soil By Sang Sook Han. In this studies, the special characteristies of soil and the various factors which exert inf-luences upon the coefficient of permeability of soil were studied through the physical experements, using Fine soil (Silt and Clay whose effective grain size is less than 0.05mm) as the study object. Especially it was tried to find out factor which exert the most important functions in the determination of the coefficient of permeability of soil, and to derive the empirical formula from which the coefficient of permealility is can be calculated. The summary of the results are as follows. 1. In the Coarse soil, the grain size plays absolute influence upon the coefficient of permeability, but in the Fine soil the grain size has little effects. 2. As regards to same Fine soil, there exist the following relation between the void ratio (e) and the coefficient of permeability (k) log k=Ae+B (Where A and B are constants) 3. As regards to the Non-plastic soil, it was found out that there exist the linear relation between k and e, even if the soil is of fine grain. 4. Regarding to the compound (or composition) shape factor(c), in case of sand the value of "c" is small and almost constant, but in Fine soil the balue of "c" is greater comparing to that of sand. 5. As regards to the Non activity clay, if the void ratio is 1, and the value "c" which is the clay constituent percentage plus the passable portion percentage to the #200 sieve, is more than 73% ?×10?cm/sec=-2.905C+5.853 but it the "c" value is 35to 72% the relation is ?×10?cm/sec=-16.555C+31.711 6. In the same kind of soil, the exist the proportional relation between the clay constituent and the Liquid limit

본 연구는 대구, 경북지역의 대학생(570명)을 대상으로 식사내용, 식사관습, 식사예절, 일본음식에 대한 인상과 시식경험 및 기호도를 조사한 것으로 그 분석결과를 요약하면 다음과 같다. 1. 음식은 항상 일인분씩 담는다’의 경우는 전체응답자의 15.5%에 불과하였고, ‘음식을 큰 접시에 모아서 담는다’의 경우는 ‘가끔 한다’가 44.8%, ‘항상 한다’가 35.8%로 나타나 큰 접시에 모아서 담는 가정이 많았다. ‘저녁은 가끔 가족이 함께 모여서 먹는다’가 59.9%로 가장 많았고, ‘항상 가족이 모여 같은 음식을 먹는다’는 끼니는 아침이 42.3%, 저녁이 23.3%, 점심이 3%로 나타나 아침에 가족이 모여 같은 음식을 먹는 경우가 가장 많았다. 2. ‘식사시 가족의 자리가 정해져 있다’고 한 경우는 전체응답자의 53.5%였고, ‘가족이 모여 식사할 경우, 연장자가 수저를 들기 전에는 먹지 않는다’는 전체의 56.4%였으며, ‘가장에게는 음식의 양이나 수가 많다’는 30.9%였다. 3. 식사예절에 대해 가장 자주 주의를 받는 것은 ‘TV를 보지 않고 먹기’(13.4%), 남기지 않고 먹기(11.5%), ‘수저사용법’(8.0%)의 순으로 나타났다. 반면 ‘식기 부딪히는 소리’(76.9%), ‘입 다물고 먹기’(76.6%), ‘씹는 소리’(74.6%), ‘밥 먹는 모양’(71.4%), ‘수저 사용법’(69.7%)등은 전체응답자의 70% 이상이 ‘주의를 받지 않는다’고 하였다. 4. 음식 만들기에 대한 선호도는 5점 만점에 3.48점으로‘보통 이상’으로 나타났고 국가별 요리에 대한 기호도는 한국요리(4.39점)가 가장 높았고, 그 다음이 중국요리 (3.76점), 이태리요리(3.45점), 일본요리(3.32점) 순이었으며 프랑스요리(3.16점)가 가장 낮은 기호도를 보였다. 음식 만드는 빈도는 한달에 1∼2회 정도로 나타나 대학 생들이 직접 음식을 만드는 빈도는 매우 낮음을 알 수 있었다. 5. 일본 방문경험은 조사대상자의 93.8%가 없었으며, 그중 92.6%가 일본방문을 희망하였고 일본음식에 대한 이미지는 ‘가격이 비싸다’(4.15점), ‘장식이 아름답다’(4.05점), ‘색채가 예쁘다’(3.98점) 등은 높은 점수를 보인 반면에 ‘맵다’(2.21점), ‘기름기가 많다'(2.51점), ’깊은 맛이 있다‘(2.56점) 등은 낮은 점수를 보였다. 6. 일본음식 중 가장 높은 시식경험을 가진 것은 우동(95.3%)이었고 그 다음은 스시(93.1%), 덴뿌라(81.9%)순 이었고, 반면에 니쿠자가(6.4%), 오차즈께(9.3%), 오코 노미야끼(11.1%), 다코야끼(16.0%) 등은 매우 낮은 시식경험을 보였다. 7. 일본음식에 대한 기호도는 우동(3.98점), 스시(3.85점), 덴뿌라(3.69점), 소바(3.43점), 스키야끼(3.12점)는 대체로 높은 기호도를 나타낸 반면 낫또(2.68점), 오차즈께(2.76점), 오코노미야끼(2.87점), 미소시루(2.88점), 다코 야끼(2.88점) 등은 낮은 기호도를 보였다. 이상의 연구결과로 변모해 가는 우리전통 식사예절의 동향 파악이 가능하였고 가족간의 화목과 건강한 사회를 이루기 위한 가족 단란의 식사지침이 요구되었다. 한편 일본음식중에는 우동과 스시가 한국대학생들에게 가장 인기가 높은 음식임을 알 수 있었고 대부분의 일본요리에 대해 장식이 예쁘고 색채가 아름답지만 값이 비싸다는 이미지를 가지고 있어서 가격을 좀 더 낮춘다면 그 이용이 더욱 늘어날 것으로 기대되었다. 또한 낫또, 오차즈께, 오코노미야끼 등 이용도가 낮은 음식에 대해서는 한국인의 입맛에 맞는 요리법을 가미한다면 대중화가 가능하리라고 여겨진다. This study was conducted to investigate the dietary behavior and image and preference of Japanese foods. The Subjects were consisted of 570 university students(243 males and 327 females) in Daegu and Kyungbuk area, Korea. The students responses to the 10 questions about image of Japanese foods were also measured on 5 point Likert scale. Data were presented by using frequency, percentage, chi-square test and T-test. The results of this study were as follows: (1) On the eating habits, 'the whole family has breakfast together with same foods everyday' scored high as 42.3% and 'foods put in a big platter by gathering everyday' as 35.8%. (2) About the eating customs, 53.5% of the subjects responded that the seat was fixed at meal time, 56.4% didn't start to eat before the patriarch started a meal and 30.9% responded that the head of a family had more foods in number and quantity. (3) On the table manners, 13.4% of the subjects were scolded about 'watching TV on eating', 11.5% about 'making left-over foods', 8.0% about 'misuse of spoon and chopsticks'. (4) The preferred ethnic foods by University students was in other of Korean, Chinese, Italian, Japanese and French foods. (5) Among subjects, 93.8% had no experience of visiting Japan and 92.6% wanted to visit Japan. Images on the Japanese foods were 'the price is too expensive' (mean 4.15) and 'the decoration is wonderful'(mean 4.05). But the subjects did not think Japanese foods as 'hot'(mean 2.21) and 'greasy'(mean 2.51). (6) The favorite Japanese food of subjects was Udon(mean 3.98), Sushi(mean 3.85) and Tempura(mean 3.69). So Udon turned out to be the most popular Japanese foods by university students in Daegu and Kyungbuk area, Korea. But they did not prefer Natto(mean 2.68), Ochazuke(mean 2.76), Okonomiyaki(mean 2.87) and Misosirn and did not eat. From the above results, Korean university students preferred Udon to Natto among Japanese traditional foods, and they estimated Japanese foods as 'too expensive'. Therefore, lowering the price and developing the cooking method for Korean taste were needed to increase the intake of Japanese traditional foods by Korean university students and.

The main purpose of this study is to investigate the effect of housewives' dietary awareness and habits on the reduction and recycling of food waste products. We have done statistical analyses of 501 questionnaires answered by housewives living in Taegu city. The results are as follows: The dietary awareness is significantly different according to the housewives' ages. The group of above 50's age, and the group of housewives and their husbands with a lower education level have a more traditional awareness and eating up habits. Also the younger group, and those with a higher education level who grew up in a big city have a more progressive dietary awareness. But the younger, higher income, small family, higher education level groups, and also employed housewives, produced more food waste products than the other groups. The groups those have traditional or rational awareness concerning dietary awareness, and those with good eating up and accurate cooking habits turned out to have more affirmative effects on the reduction and recycling of food waste products.

家族計劃과 母子保健의 相關性에 關한 硏究

韓聖鉉,방숙 순천향대학교 1981 논문집 Vol.4 No.3

The basic purpoae of this study wag to examine the effects of family planning practice on maternal-child health.Within this framework, the study planned originally to include two specific 0bjectives; a) to what extent twas the use of family planning brought about changes in the familybuilding process either through family limitation or spacing ? b) have such changes in family building precess in turn influenced positively or negativelyother features of family life such as health care usage and the health status of the family. The Kangwha area, wish a population of 13,000 in three townships. has been used byYensei University since 1974 as a community health project demonstration area. A sam le survey was carried out in the area of Kangwha in May 1980. Households were sampled with cluster to produce a sample of 939. Of these, 502 e1igib1e women were interviewed, The following is a summary of the research findings. 1. Fertility level is lower than national data. 2. Family formation is building quickly with limitation of birth and no spacing. 3. Family planning practice in the study area can he generaly characterized as having high acceptance but low efficiency the family planning practice rate increased from 38 percent in 1974 to 69 percent in 1980. An analysis of contraceptive methods used avows a gradually shift by young age group from temporary to permanent methods. 4. In Kangwha, the FP-MCH program has been succesaful to a degree in reducing the abortion rate below the national average. 5. Family planning users hove a mean closed interval of 45 months compared to 26 months for non-users and a mean open interval of 38 mouths compared to only 15 months for non- 6. A composite rise scorn for index birth was developed using the variab1es maternal age, parity, birth interval, pregnancy wastage history and maternal education level. The evidence showed a strong negative correlation between the risk score and birth weight. However, The data also indicated negative correlation with prenatal care usage. 7. Shorter inter-birth intervals'are associated 'with high health risks'for both mother and child. The ength of the open birth interval seers to impact on health care behaviour. The survey findings as well as information gleaned about the health system from under taking the study itself point to several policy implications. Administratively, management of family planning and MCH programs might be integrated in several ways; -Identify at rise groups in order to concentrate limited resources. -Introduce multi-purpose worrkers on the local level who are trained to provide comprehensive health care.

한강석,국중기,유소영,김화숙,박종휘,박현동,이상훈 大韓小兒齒科學會 2003 大韓小兒齒科學會誌 Vol.30 No.3

레이저의 구강내 산 생성 세균인 S. mutans에 대한 증식 및 기능 억제효과를 평가하기 위하여 S. mutans KCTC 3065가 포함된 세균 pellet에 Er:YAG 레이저와 Nd:YAG 레이저를 비접촉식 방법으로, 조사세기 50mJ, 조사시간 5초, 그리고 pulse repetition rate를 각각 10Hz와 30Hz로 하여 조사하고 세균 군락수, 산 생성능, 불용성 세포외다당류의 합성량을 측정하여 다음과 같은 결과를 얻었다. 1. Chinese ink로 photosensitization을 시행한 후 Nd:YAG 레이저를 조사한 경우가 S. mutans의 증식을 가장 많이 억제하였으며 Er:YAG 레이저 조사도 증식을 억제하였다. Chinese ink를 사용하지 않고 ND:YAG 레이저를 단독으로 조사한 경우는 S. mutans의 증식을 억제하지 못하였다. 2. Chinese ink로 photosensitization을 시행한 후 Nd:YAG 레이저를 조사한 경우가 일정기간 동안 S. mutans의 산생성능을 가장 많이 억제하였으며 Er:YAG 레이저 조사도 산 생성능을 억제하였다. Chinese ink를 사용하지 않고 Nd:YAG 레이저를 단독으로 조사한 경우는 S. mutans의 산 생성능을 억제하지 못하였다. Er:YAG 레이저와 Chinese ink로 photosensitization을 시행한 후 Nd:YAG 레이저를 조사한 경우는 pulse repetition rate가 클수록 전반적으로 세균의 산생성능을 더 많이 억제하였다. 3. 레이저 조사는 S. mutans의 불용성 세포외다당류의 합성에 영향을 미치지 못하였다. 이상의 결과로 보아 Er:YAG 레이저와 Chinese ink로 photosensitization을 시행한 후의 Nd:YAG 레이저 조사는 일정시간 동안 S. mutans의 증식과 산 생성능을 억제시키므로써 치아우식증 예방효과를 얻을 수 있다고 사료되나 억제효과가 오래가지 않아 임상적으로 효과를 얻기 위해서는 자주 조사를 해주어야 한다는 문제점을 안고 있어 임상적으로 치아우식증 예방이란 단독 목적으로 사용하기에는 실용성이 크지 않다고 사료된다. This was performed to evaluate the inhibitory effect of laser on the growth of S. mutans. The bacterial pallets containing S. mutans KCTC 3065 were irradiated with Er:YAG laser and Nd:YAG laser by non-contact method at an intensity of 50mJ for 5 sec with the pulse repetition rates of 10Hz and 30Hz, respectively. The following results were obtained on colony count, acid producing ability, and the amount of insoluble extracellular polysaccharide synthesis. 1. The irradiation of Nd:YAG laser after photosensitization with Chinese ink inhibited the proliferation of S. mutans the most, and the irradiation of Er:YAG also inhibited the proliferation. However, the irradiation of Nd:YAG laser alone could not inhibited the proliferation of S. mutans. The pulse repetition rate did not affect significantly on the proliferation of bacteria in overall. 2. The irradiation of Nd:YAG laser after the photosensitization with Chinese ink inhibited the acid production of S. mutans the most for a certain period of time. Er:YAG laser also inhibited acid production. When Nd:YAG laser was used alone, the acid production of S. mutans was not been inhibited. The irradiation of Nd:YAG laser after photosensitization with Chinese ink inhibited the acid production ability of bacteria the most as the pulse repetition rate increased. 3. Laser irradiation did not inhibited the synthesis of insoluble extracellular polysaccharide of S. mutans. From these results, we conclude that the irradiatioin of Er:YAG laser and Nd:YAG laser after photosensitization with Chinese ink would inhibit the proliferation and acid production by S. mutans, which may prenent dental caries. However, this effect does not last long time so that the laser irradiation should be repeated frequently in order to obtain clinical effect; thus, this laser irradiation would not have a clinical usefulness in preventing dental caries when used solely.

본 연구의 목적은 학습장애아동에 대한 심리학적 평가를 소개하는데 있다. 소개에 앞서 학습장애아의 개념면에서의 정의, 교육적 의미, 원인 및 학습장애아동의 특성을 알아보았다. 학습장애아동에 대한 심리학적 평가는 신체 및 신경생리학적 평가, 인지기능의 평가, 학업수행의 평가, 정서행동의 평가로 나누어 설명하였다. 신체 및 신경생리학적 평가를 위해서는 신체검사, 아동의 성장사, 벤다-형태검사, 웩슬러 기억검사, 루리아 네브라스카 신경심리검사 등을 소개하였다. 인지기능의 평가를 위해서는 고대-비네검사, 한국교육개발원-웩슬러 아동용 지능검사, 인물화검사, 시각-운동 통합발달검사를 소개하였다. 학업수행의 평가를 위해서는 각종 성취검사, 읽기검사 등이 있으나, 우리나라에서는 각종 표준화된 학력검사가 충분히 개발이 안되어 있어서 일선 학교에서는 자체적으로 시행하는 학력고사를 통하여 전반적인 학업수행과 각 과목내의 잘하는 영역과 못하는 영역을 평가하고 있다. 정서행동의 평가를 위해서는 아동과의 면담, 교사 및 부모의 평가, 각종 심리검사가 시행되고 있다. 마지막으로 학습장애아동을 평가하고 교육하기 위해서는 평가도구가 개발되고 이에 따라 교육할 수 있는 적절한 프로그램 및 교육시설이 마련되어야 할 것이다. The purpose of this study was to present a psychological assessment of learning disabled children. In order to do so, we investigated definitions, educational meanings, causes and characteristics of learning disability. Psychological assessment of learning disabled children was explained four distinct categories including physical and neurophysiological characteristics, cognitive function, academic performance and affective behaviors. First, in order to assess physical & neurophysiological characteristics of learning disabled children, there were physical examination, history of children, Bender Gestalt Test, Wechsler Memory Scale, Luria-Nebraska Neuropsychological Battery et. al Second, there were Ko-Dae Binet Test, Draw A Person Test, Developmental Test of Visual-Motor Integration for the purpose of assessing cognitive function. Third, for academic performance, there were several achievement test and reading test. But we have not psychological test for the purpose of academic performance. Instead, we have enforced academic achievement ability to assess general academic performance and domains of assets & weaks in interview with children, assessment of teacher & parents and psychological tests. Finally, to assess and educate learning disabled children, we have to develop instruments of assessment and to provide appropriate educational programs and equipments using it.
