Foreign bodies in the air way are not uncommon conditions in the otolaryngological fields. Numerous cases are reported by many authors. This case report is concerned with five cases of various respiratory tract foreign bodies removed under the bronchoscopic control, recently experienced by authors. Case 1; A metal zipper was found at the right main bronchus and was removed by brochoscopy in a 10 year-old-boy. Case 2; A stainless coverage piece of a umbrella was packed at the right main bronchus in the 5-year-old boy and was removed by bronchoscopy. Case 3; A half splitted peanut in the right main bronchus was removed by bronchoscopy in a 18 months-old baby. Case 4; A apple see dcase was lodged in the right main bronchus and was removed by bronchoscopy in a 6 months-old baby.

This study explores the types of daily routines in child care centers based on the time planned for indoor free choice activities, outdoor activities, group activities and nap/rest. The daily routine plans of 63 classes of 0 to 2-year-olds and 51 classes of 3 to 5-year-olds were cluster analyzed. Also, openness and closeness of child care programs as well as the most participated indoor/outdoor activities were examined using questionnaires developed for teachers. The results were as follows: First, teachers planned the most time for free play choice activity and comparatively less time for outdoor play during the day. Time for rest and naps were planned more for 0-2 year-olds whereas group activities were planned more for the 3-5 year-olds. Second, 3 daily routine types were found in the daily plans of child care centers, such as "Low-Activity Oriented," "Free Choice Activity Oriented" and "Group Activity Oriented" in 0 to 2-year-old classes and 3 to 5-year-old classes. Also, "Group Activity Oriented" type in 0 to 2-year-old classes showed more "closed" child care programs than the "Free Choice Activity Oriented" type. However, no difference was shown among the 3 types of daily routines in the openness and closeness of 3 to 5-year-old child care programs. Finally, all children, regardless of the types of daily routine, participated most in block activity and role play indoors and fixed-play equipment, sand play and free play outdoors.

This study investigated the determination of speech rates, words per minute (WPM) and syllables per minute (SPM), of $5{\sim}7$ year-old normal children to understand if there are any differences in the rates according to the children's age and sex. All participants were required to conduct story retelling tasks (SRT) and picture description tasks (PDT). In SRT, there was a significant difference between the groups of 5 year-old and 7 year-old children on WPM. However, there was no significant difference between the groups of ages regarding SPM. In addition, there was no significant difference between the groups according to sex on WPM and SPM. In PDT, there was no significant difference between the groups according to their ages and sex on WPM and SPM. The current research found that the speech rates of the preschool children might be somewhat different in their utterance abilities according to their age, but there was no obvious difference according to their sex. The findings can advance development of a clinical tool to screen children with fluency disorders and to determine the steps in establishing speech rates of children in the language development period.

This experiment was conducted to investigate the morphological and structual characters and the dry weight of plant (DW/pl.) concerned vegetational structure of orchardgrass pastures by the times of year, from 1 year to 7 year previous, 1986 through 1980, alternately. this experiment was carried out on the experimental fields of Yonsei University. The results are summarized as follows: 1. Population density (PD) was extremely decreased by the times of year. 2. Pasture productivity was highest at 3 year old pasture, was lowest at 5 year old pasture and was recovered at 7 year old pasture. 3. Recovery of pasture productivity was followed the increase of dry weight of plant (DW/pl.) and number of tillers per plant (NT/pl.) 4. The population density of 7 year old pasture was 14 plants per square meter. 5. The number of tillers per plant (NT/pl.), dry weight of plant (DW/pl.) plant length (PL), and plant size (PS) was frequently showed the highest values by the times of established year. 6. The stubble diameter (DIA), stubble area (SB), plant size (PS), distance between neibour plant (DIS) and leaf area index (LAI) was increased according to the times of year. 7. The dry weight of plant (DW/pl.) was positively significant correlations with the number of tillers per plant (NT/pl.) all of the established pastures, but the dry weight of a tiller (WT) was tended to increase of correlations with the dry weight of plant (DW/pl.) by the times of year. 8. Differences between morphological and structual characters was recognized according to the times of year.

Objectives The purpose of this study is to investigate recent trend of diseases in Korean pediatrics and adolescent patients treated with oriental medicine. Methods Using data from the Korean statistical information service and healthcare bigdata hub, top 500 diseases pediatrics and adolescents that were treated with oriental medicine from 2012 to 2016 in admission and outpatient department was collected. Results From the inpatient study, majority of the subjects were between 15 to 19 years old (62.74%), followed by 10 to 14 years old, 5 to 9 years old and under 5 years old. In the outpatient department study, majority was 15 to 19 years old (36.51%), followed by 10 to 14 years old, under 5 years old, 5 to 9 years old. In systemic division of admission part, the most common disease was musculoskeletal related which was 72.32%, followed by brain, nerve, respiratory, dermatology and digestive related diseases. In systemic division of outpatient department, respiratory disease was the most common (41.81%), followed by digestive, dermatology, brain and nerve diseases. For under 5 years old patient group, respiratory disease was the most common, 29.86%, followed by dermatology, musculoskeletal, digestive related diseases. For 5 to 19 years old group of patients, musculoskeletal disease was most common. For the 5 to 14 years old patient group, respiratory related disease was the most common followed by dermatology and digestive diseases. For 15 to 19 years old patient group, digestive disease was the most common followed by respiratory and dermatology related diseases. For under 5 to 9 years old outpatient group, respiratory disease was the most common, and for under 5-year-old group, digestive, growth development, and dermatology disease were common. For the 5 to 9 years old group of patients, musculoskeletal related disease was the most common followed by digestive and dermatology related diseases. For the 10 to 19 years old patient group, musculoskeletal was the most common. For the 10 to 14 years old patient group, respiratory related disease was the most common followed by digestive, dermatology disease. For the 15 to 19 years old patient group, digestive related disease was the most common followed by respiratory, dermatology diseases. Musculoskeletal disease increased every year, in both inpatient and outpatient. Respiratory, brain, nerve, digestive related diseases were generally decreased. In outpatient, respiratory diseases were increased every year but brain, nerve, digestive related diseases were generally decreased. Conclusions More studies about the oriental medicine in chronic disease, such as allergy, metabolic syndrome, in Korean pediatrics and adolescents are needed.

The aim of this study was to investigate the relationships of mothers' authoritative and authoritarian childrearing attitudes to their 5-year-old children's attachment representations and to teacher-rated social competence. The sample consisted of 69 mothers and their 5-year-old children from intact families. Children were interviewed to assess the quality of their attachment representations using Slough & Greenberg's(1990) version of the Separation Anxiety Test(SAT). Mothers were administered the Childrearing Practices Report Q-sort(Block, 1965) and filled out questionnaires regarding their childhood experiences, their marital relationship and their psychological well-being. In addition, teachers rated children's social competency in school settings using Kohn's(1972) Social Competence Scale. Hierarchical multiple regression showed that mothers' high scores on affective components of authoritative parenting and low scores on authoritarian attitudes are closely associated with children's secure attachment as well as teacher-rated social competence.

In order to clarify an effect of seedling weight on the growth pattern of ginseng, seedlings ranged from 0.4g plant to 1.8g plant were transplanted, and then the characters of 5- and 6-year-old ginseng were investigated. The characters of root and leaf, such as length and diameter of main root, root weight, leaf area, and leaf dry weight of 5- and 6-year-old ginseng originated from large seedlings were superior as compared with those from small seedlings, and percentage of missing plant was increased with the increase of seedling weight. There were, however, no significant difference in stem length, stem dry weight, number of seeds per plant and number of palmate leaves and leaflets per plant in 5- and 6-year-old ginseng and these characters were not affected by the weight of seedings transplanted. Root field per unit area was higher in seedings of above 0.6g/plant than in small seedlings.

The purpose of this study was to obtain baseline data for developing oral health education program. The questionaire about oral health knowledge and behaviors were given to 1419, 12 year-old children who lived in Seongnam City. The results were obtained as follows; 1) Of respondents, 46.2% visited dental offices within a year. And 33% of them were for the purpose of routine examinations and prevention. 2) 67.1% of them exhibited toothbrushing before bedtime and only 11.3% and 8.9% of them toothbrushed after between-meal intake and lunch. 3) 47.7% of them experienced dental health education programs and 72.3% of the programs had been during elementary school days. 4) 56.2% of them chose dentifrices without standards and 21.6% of them considered the presence of fluoride. 5) Of respondents, 57.4% and 46.4% knew the importances of toothbrushing and dietary pattern. But only 18.7% and 8.5% of them knew the methods of using fluoride and scaling. 6) 33% of them replied negatively to the probabilities of preventing dental caries. 7) Also, it is necessary to expand the oral health education programs for 12 year-old children in Seongnam City and include the annual screening dental examination, toothbrushing, dentifrice selection, using fluoride and scaling.

The dietary fiber and crude fiber contents of different thallus regions (blade, stipe, and holdfast) in three brown algae (Laminaria japonica, Ecklonia stolonifera, and E. cava) were detennined at different ages, and then compared with one another. On a dry matter basis, the soluble dietary fiber (SDF) content was highest ($10.8{\pm}0.5%$) in the holdfast of 2-year old L. japonica, and the insoluble dietary fiber (IDF), total dietary fiber (TDF), and crude fiber (CF) contents were highest in the holdfast of 2-year old E. cava at $44.5{\pm}0.7%$, $50.2{\pm}0.5%$, $6.8{\pm}0.7%$, respectively. The IDF, TDF, and CF contents of these three species were measured in the following order: holdfast > stipe > blade, and the SDF contents of L. japonica exhibited the reverse of this trend. The TDF/CF ratio of 1-year old L. japonica, E. stolonifera, and E. cava was greater than was observed in the corresponding 2-year old samples. This is, to the best of our knowledge, the first report demonstrating that the holdfasts of L. japonica, E. stolonifera, and E. cava are rich in dietary fiber contents, especially IDF, TDF, and CF.
