주성범 한국체육무용과학회 2023 Journal of Sport and Dance Science Vol.3 No.2

본 연구는 한국의 키성장 운동프로그램에 참여하는 학생들과 학부모들을 대상으로 키성장과 관련한 내용을 설문조사를 통해 알아보고자 하는 것이다. 키성장 운동프로그램에 참여하는 각각 초등학생 97명 과 학부모 97명을 대상으로 하였으며, 키성장 관련된 변수들을 학생과 학부모를 대상으로 나누어 1-6번 항목으로 구성하였다. 연구결과에서 학생들의 키성장 기대치와 학부모의 자녀 키성장 기대치는 유사한 경향이 나타났다. 학 생들이 현재 자신의 키성장 및 성인이 된 후의 키성장에 대해 걱정수준에서는 학부모들이 현재 자녀의 키성장 및 성인이 된 후 키성장에 대해 걱정수준에서는 ‘전혀 그렇지 않다’나 ‘그렇지 않다’는 응답 비율 이 약 60%로 높게 나타났다. 이를 통해 키성장에 대한 걱정수준이 높지 않음을 확인할 수 있었다. 학생 들의 경우, 운동이 키성장에 도움이 될 것이라는 긍정적인 응답인 ‘그렇다’와 ‘매우 그렇다’가 86.6%이며, 학부모들도 87.6%로 매우 높게 나타났다. 키성장 운동프로그램이 다른 운동보다 키성장에 더 도움이 될 것이라고 생각하는 비율은 학생과 학부모 모두 80% 전후로 높게 나타났으며, 키성장을 위해 키성장 운 동프로그램에 계속 참여하고 싶다는 비율도 학생과 학부모 모두에서 90% 전후로 높게 나타났다. 마지막 으로 학생들과 학부모 모두 성인이 되었을 때 원하는 평균 키가 170cm 초반으로 나타났다. 이러한 연구결과는 키성장 운동프로그램 참여하는 학생들과 학부모의 키성장 기대치에 관한 구체적인 정보를 제공할 수 있을 것이다. 이는 앞으로의 키성장 운동프로그램을 개발하고 적용하는데 있어 매우 유용한 자료로 활용될 것으로 기대된다. Objectives This study aims to explore aspects related to height growth among students and parents participating in height growth exercise programs in South Korea through a survey. Methods The survey targeted 97 elementary school students and 97 parents, respectively, dividing height growth-related variables into six items for both students and parents. Results The research findings indicated a similar trend between the height growth expectations of students and those of their parents. Regarding concerns about current height growth and future growth after reaching adulthood, both students and parents showed a high rate of responses indicating not at all concerned or not very concerned, at approximately 60%. This suggests that there is a relatively low level of concern about height growth. Students, in particular, responded positively regarding the belief that exercise would contribute to height growth, with 86.6% responding yes or strongly yes, while parents also responded positively at 87.6%. The percentage of participants who believed that the height growth exercise program would be more beneficial for height growth compared to other exercises was approximately 80% for both students and parents. Additionally, the willingness to continue participating in the height growth exercise program to support height growth was high, with around 90% of both students and parents expressing interest. Lastly, both students and parents indicated an average desired adult height in the early 170cm range. Conclusions These research findings provide specific insights into the height growth expectations of students and parents participating in the height growth exercise program. This information is expected to be highly valuable for the future development and implementation of height growth exercise programs.

A Study on the Progress of Growth Promotion in Koreans by Maximum Growth Age for Height

Park, Soon-Young,Park, Jung-Min,Nam, Byung-Jip Korean Society for Health Education and Promotion 2002 보건교육건강증진학회지 Vol.19 No.4

Since growth promotion was defined by Koch(1935), many researches like Benholdt and Thomsen(1942) have conducted studies for understanding problem of puberty growth. Growth promotion means that growth is developed in puberty, and several researchers have reported that the more becomes economic growth, the more becomes growth promotion. Thereupon, this study was attempted to find Maximum Growth Age(M.G.A.), as an index of height growth promotion in Korea, which was obtained by longitudinal observations of the same group. Thus, this study can explain the earlier tendency of growth. To investigate domestic changes in M.G.A., M.G.A. was calculated with the results of cross-sectional researchs using 25 representative papers between 1940-1953 including measurements by Lee(1940) and data by Kim(1953) in this study. Based on the research data published between 1940 and 2000, height and M.G.A. of males and females who were born between 1925 and 1983 were gotten by years, and a trend of growth promotion for height in Koreans was suggested by examining study subjects. Findings of this study are as follows; 1. M.G.A. for height decreased both in males and females; for males, 14.28 years in 1940, 14.24 in 1953, 13.86 in 1967, 12.74 in 1985, and 11.71 in 2000; for females, 12.0 in 1940, 11.52 in 1965, 10.00 in 1978 and 9.77 in 2000. 2. Regression equations and standard errors of estimate concerning M.G.A. for height by years were obtained; for males, Y$_1$(M.G.A.) = 17.21 - 0.059X$_1$, S$_{Y1X1}$(standard error of estimate about the regression line) = ${\pm}$0.62; for females, Y$_2$(M.G.A.) = 13.81-0.042X$_2$, S$_{Y2X2}$(standard error of estimate about the regression line) = ${\pm}$0.64 3. As a result of finding correlation between year and M.G.A. r=-0.763 (p<0.001) for male and r=-0.699(p<0.001) for female were obtained 4. From a view that the growth promotion has been continued before 2000, M.G.A. decreased 0.6 years for male and 0.4 for female per 10 years. 5. M.G.A. for height is as shown in Table 2. 6. It is thought that the future trend of growth promotion for height will follow the progress from 1940s to now. It shall be reviewed again after development of coming several years is investigated.

Recently, as interest in appearance has increased, various studies on treatment method for short stature are being conducted. In this study, the effect of growth plate stimulation on the height growth of children and adolescents was studied. As a result of pre- and post-analysis of the experimental group, it was confirmed that the difference in average height according to growth plate stimulation was relatively large. In addition, in the results of analyzing the effects of demographic factors on the height growth of the experimental group and the control group, weight showed the greatest influence on height growth among the demographic factors affecting the height growth of the experimental group. The effect on the height growth of the control group was found to have an effect in the order of age, weight, and father’s height. The difference in height changed post-mortem between the experimental group and the control group was 1.10 cm for 3 months, and the difference was the result of growth plate stimulation. It was confirmed that growth plate stimulation had a significant effect on the height change of children and adolescents, except for weight, which is a common factor of height change in the experimental and control groups. Therefore, it is expected that it can be used as a treatment method for short stature.

Assessment of the effects of thinnings in scots pine plantations in Mongolia: a comparative analysis of tree growth and crown development based on dominant trees

Batsaikhan Ganbaatar,Tsogtbaatar Jamsran,Alexander Gradel,Gerelbaatar Sukhbaatar 한국산림과학회 2021 Forest Science And Technology Vol.17 No.3

The post-thinning stand density and spacing in forest plantations influence individual tree growth and crown development, and the changes detected in dominant tree growth are a good indication of the thinning effect. The objective of this study was to determine the effects of different thinning intensities on diameter and height growth in a Scots pine (Pinus sylvestris L.) plantation. The field measurements were carried out between 2016 and 2020 on a Scots pine plantation, growing in Selenge province of northern Mongolia. Following this, experimental thinnings were carried out with different intensities. Thinning treatments comprised thinning with very low, low, medium, and high intensities, as well as an unthinned control stand. Stem analyses were performed to calculate the annual and cumulative diameter, height, and volume growth. For tree crown measurements several parameters were analyzed: crown diameter, crown projection area, and crown index. A total of 300 trees (5 treatments3 replications20 dominant trees from each plot) were subjected to the comparative analyses. This study revealed that thinning showed a stronger positive effect on diameter and volume growth of dominant trees in the plantation. Our results showed a gradual increase in diameter, basal area, and volume growth depending on the thinning intensity. An ANOVA test for growth analyses of dominant trees showed a significant difference in diameter (p<0.0001) and height (p<0.0001) growth performance following experimental felling with different thinning intensities. Finally we elaborated linear mixed effect models (LMM) for tree growth between 2016 and 2020 of selected dominant trees. With the help of the LMM we analyzed and described the thinning impact on DBH, BA, height, volume and crown diameter. The models confirmed that higher thinning intensity triggered growth of the response variables except for height. A greater height growth was found in very low (10%) and low (15%) intensity treatments. Due to reduction of competition and optimization of the distance between individuals, thinnings contributed to a relatively faster development of the tree crown in radial directions. Based on our analysis results and comparative graphs representing post-thinning dominant tree growth in diameter, height, basal area, and volume, we recommend medium- (30%) and high-intensity (45%) thinnings as at the beginning stage of plantation establishment.

Purpose : Growth-promoting attempts are widespread in Korea, but little is known about their prevalence or associated factors. This study was designed to assess the prevalence of growth-promoting attempts among children visiting a university growth clinic. Methods : A questionnaire-based survey was carried out with 823 children (416 boys, 407 girls) who visited the growth clinic at Paik Hospital. Results : The mean age of the subjects was 10.4±2.6 yr, and the height z-score was -1.58±0.91. Approximately 33.4% of the children had tried growth promotion. Among the height-gain methods, herbal medicine was the most frequently used (37.8%), followed by health-promoting supplements (37.1%), exercise or machine (3.0%), and growth hormone treatment (2.9 %). The mean age at which the parents began to worry about their children's height was 7.7 yr. The mean age at which they started height-gain methods was 8.9 yr for herbal medicine, 9.1 yr for health-promoting supplements, 9.4 yr for exercise or machine, and 9.9 yr for growth hormone treatment. Motivating factors included advice from relatives or friends (36.0%), advertisements in the Internet or newspaper (28.4%), advice from pharmacist (16.8%), and advice from their medical doctor (5.5%). The degree of satisfaction from the height-gain methods was 29.1% with growth hormone treatment, 6.6% with exercise or machine, 6.4% with herbal medicine, and 2.8% with growth-promoting supplements. Conclusion : Approximately one third of the children reported use of growth-promoting methods, but the satisfaction rate was not high. The benefits of growth-promoting methods should be carefully weighed against their costs and side effects. 목 적 : 현재 우리나라 아동들은 키를 더 크게 하려는 여러 가지 인위적인 노력이 만연되고 있으나 그 실태 분석에 관한 연구는 드물다. 이에 본 연구에서는 성장클리닉을 방문한 아동들에서 키를 크게 하기 위해 인위적 관리 실태를 조사하고자 하였다. 방 법 : 상계백병원 성장클리닉을 방문한 아동 823명(남아 416명, 여아 407명)을 대상으로 키 성장을 위한 인위적 관리실태에 관한 설문지 조사를 시행하였다. 결 과 : 성장클리닉을 방문한 아동의 평균연령은 만 10.4±2.6세였고 신장의 z-score는 -1.58±0.91였다. 키를 크게 하기 위해 인위적인 관리를 한 경우는 전체의 33.4%였다. 키를 크게 하기 위해 인위적 관리를 받은 아동 중에서, 한의원에서 성장촉진 한약 및 성장보조약을 복용한 경우가 각각 37.8%로 가장 많았고 성장호르몬 치료를 받은 경우가 2.9%였다. 영양제나 건강보조식품을 먹인 경우 종합비타민 및 무기질제가 42.6%로 가장 많았고 키 큰다는 성장보조제(영양제+생약성분) 23.9%, 단일 칼슘제 19.1%, 클로렐라 7.7%, 초유 6.7% 순서였다. 부모님이 자녀의 키에 대해 고민을 시작한 나이는 평균 7.7세였으며 키 성장을 위한 인위적 관리를 시작한 평균연령은 한약 8.9세, 성장보조제 9.1세, 운동/기구가 9.4세, 병원치료 9.9세의 순서였다. 키 성장 관리를 시작하게 된 동기 중에는 친지의 권유가 36.0%로 가장 높았고, 인터넷 및 언론 광고 28.4%, 약국에서의 권유 16.8%, 병원 의사의 권유 5.5%였다. 사용 후 만족도는 성장호르몬치료가 29.1%로 가장 높았고 운동/기구는 6.4%, 한약은 6.6%, 성장보조제는 2.8 %로 가장 낮았다. 결 론 : 대학 병원 성장클리닉을 내원한 아동의 1/3에서 키를 크게 하기 위한 인위적인 관리를 이미 하고 있었으나 효과에 대한 만족도는 높지 않았으며 여러 성장촉진 보조요법에 대한 의학적 견지에서의 성장 작용 및 부작용에 대한 객관적 비교분석이 조속히 이루어져야 하리라 사료된다.

The purpose of the study was to investigate the effects of exercise function and height growth for 12 weeks customized exercise program on growth stage in low-height students. For this study, I conducted a 12 - week personalized exercise program for 40 low-height students who came to K-Growth specialization center for training. The factors of flexibility(cm), VO2max(ml/kg/min), leg muscle function (Peak TQ / BW %), waist muscle function (Peak TQ / BW %), and growth of height(cm) were analyzed. The physical functions(flexibility, VO₂max, leg muscle function, waist muscle function), and growth rates(growth of height) were measured at the beginning of the exercises(1st) and after 12-weeks exercises (2nd). For the data, all measurements are represented by mean and standard deviation using SPSS statistical package(version 23.0). Statistical level of significance was set up as a=.05. In conclusion, for body function, the increase of flexibility, VO₂max, and leg & waist muscle function, are necessary and important for growth. It is worth mentioning that exercise program works best especially in general growth period and fast growth period. Therefore, doing customized exercise program regularity from childhood is conducive to height growth.

Objectives : The aim of this study was to observe and analysis the effectiveness of clinical treatments on the growth of children treated with Korean herbal medicine (KHM). Methods : Forty-two children of growth retardation were evaluated from January 2007 to May 2008. All children were administered KHM with diet and exercise guidance. Height percentile and predictive height were calculated following the General Growth Statistics Result (2007), and compared those of pre-treatment with post-treatment. Results : Thirty-one of them were improved (73.8%) and eleven were not (26.2%). The mean growth rate was 7.2cm/yr for male and 6.8cm/yr for female. The mean growth percentile of male showed 7.6% improvement (p=0.003), female 4.4% respectively (p=0.036). The mean predictive height of male showed 2.2cm improvement (p=0.005), female 1.0cm respectively (p=0.007). Change of growth percentile and predictive height were significantly higher on period of prepuberty, and in small children below 50% of height percentile. About inter-relations between growth improvement and compliance of diet, exercise or medication, meaningful statistics were shown in diet control than the others (p=0.077). Diet compliance was in close connection with exercise, but others were not shown close correlations. Conclusions : These results showed that KHM showed promising results on children growth and healthy diet would be an important factor for growth of children. And it was recommended that KHM should be applied on period of prepuberty and smaller than average height.

김소담,박인협 한국환경생태학회 2019 한국환경생태학회지 Vol.33 No.4

완도수목원내 백운로 상부의 붉가시나무림을 대상으로 난대 상록활엽수림 복원 시 붉가시나무의 성장 및 종실공급과 관련된기초정보를 제공하는 목적으로 붉가시나무의 성장 및 결실특성을 조사하고 종실량 상대성장식을 구하였다. 성장특성은 평균흉고직경급에 속하는 실생 임목 3주의 표본목을 선정 벌목하여 수간석해하였다. 표본목의 평균치의 수령(X)에 의한 흉고직경과수고의 성장특성(Y)의 상대성장식(Y=aX+b)을 개발하였으며, 추정식에 의한 붉가시나무 수령에 따른 흉고직경 및 수고를추정하였다. 결실특성은 성숙종실초기인 8월에 평균 흉고직경급에 속하는 임목을 대상으로 결실이 충실한 임목 3주의 표본목을선정 벌목하여 조사하였다. 붉가시나무의 종실량 상대성장식을 개발하기 위하여 결실목 중 흉고직경이 고르게 10주의 표본목을선정 벌목하였다. 벌목한 표본목은 흉고직경, 수고, 수관폭, 수관고 등의 성장특성(X)과 종실량(Y)을 조사 분석하여 종실량상대성장식(Y=aXb )을 유도하였다. 표본목 평균치의 수령에 의한 상대성장식은 흉고직경 Y=0506X-2.064(R2 =0.999), 수고Y=0.321X+0689(R2 =0.992)이었다. 개발된 상대성장식에 의하여 수령 10, 20, 30, 40년일 때 흉고직경은 각각 3.0㎝, 8.1㎝, 13.1㎝, 18.2㎝, 수고는 각각 3.9m, 7.1m, 10.3m, 13.5m가 되는 것으로 추정되었다. 결실특성 조사 결과 결과모지(結果母枝) 당 잎 수를 제외한 결과모지의 길이, 직경, 결과모지 당 결과지 수, 종실 수는 유의적인 차이를 보였으며, 수관 상, 중, 하부로갈수록 감소하였다. 종실 총수의 경우 수관 상, 중, 하부 각각 1,312립, 115립, 5립이었다. 붉가시나무 표본목을 일괄하여추정한 종실량 상대성장식의 흉고직경(D)를 독립변수로 하는 상대성장식은 Y=0.003X4.260 , 결정계수(R2 )은 0.896이었다. 흉고직경만을 독립변수로 하는 상대성장식은 흉고직경과 수고(D2 H)를 독립변수로 하는 결정계수가 다소 낮으나, 측정오차를고려하면, 흉고직경만을 독립변수로 하는 상대성장식을 적용하는 것이 실용적이라고 판단된다. This study examined the growth and fruiting characteristics and the acorns biomass allometric equation of Quercus acuta to provide reference data related to the growth and seed supply during the restoration of evergreen forest in the warm temperate zone in Wando Island, Korea. For the growth survey, we selected and cut three sample trees having a mean diameter at breast height (DBH) to investigate the growth analysis through a stem analysis. We then developed the allometric equation (Y=aX+b) of DBH and tree height growth characteristic (Y) according to the average tree age (X) of sampled trees and estimated the DBH and tree height according to the age of Quercus acuta. For the fruiting survey, we selected and cut three sample trees with full fruit in August when, they are at the early mature fruiting stage, for the analysis. To develop the acorns/tree biomass allometric equation of Quercus acuta, we selected and cut ten sample trees of evenly divided diameters. The acorns biomass allometric equation (Y=aXb ) was derived by analyzing the biomass (Y) and the growth characteristics (X), such as the DBH, tree height, crown width, and crown height. The allometric equations of average tree age according to DBH and tree height were Y=0506X-2.064 (R2 =0.999) and Y=0.321X+0689 (R2 =0.992), respectively. The developed allometric equations estimated that the DBH were 3.0㎝, 8.1㎝, 13.1㎝ and 18.2㎝ while the tree heights were 3.9m, 7.1m, 10.3m, and 13.5m when the tree ages were 10, 20, 30, and 40 years, respectively. The analysis results of fruiting characteristics showed that the length, the diameter, the number of fruits, and the number of acorns per fruiting branch had the statistically significant difference and tended to decrease from the upper part to the lower part of crown downward. The total number of acorns was 1,312 acorns/tree in the upper part, 115 acorns/tree in the middle part, and 5 acorns/tree in the lower part of the crown. The allometric equation for the amount of acorns with DBH as an independent variable was Y=0.003X4.260 with the coefficient of determination at 0.896. Although the coefficient of determination of the allometric equation using only DBH as the independent variable was lower than that using DBH and tree height (D2 H), it would be more practical to consider only DBH as the independent variable because of measurement errors.

버즘나무의 1 ㎡당 생육 밀도에 따른 묘목의 생장은 49본구에서 묘고(tree height)와 근원직경이 우수한 생장량을 보인반면 생육밀도가 높은 처리구는 근원직경과 간장생장이 감소하는 경향을 보였다. 이는 생육밀도가 묘목의 생 장에 크게 영향을 미치는 중요한 요인으로 판단할 수 있으며, 엽록소함량에서도 생장이 우수한 49본구가 4.3 ㎎/gㆍw.t로 생장이 떨어지는 90본구의 2.9 mg/gㆍw.t에 비해 상대적으로 높은 함량을 나타냈다. 물질생산량은 생장 특성과 마찬가지로 49본구 처리구에서 전체 물질생산량이 통계적으로 유의적인 차이를 보이면서 3.12±0.80 g로 다른 처리구보다 높은 물질생산량을 보였다. 수목은 생육 환경조건에서 적절한 공간의 확보를 통하여 궁극적으로 높은 물질생산량을 보이면서 생리적으로 안정된 생장형태를 보였다. 이는 생육에 필요한 적정 공간의 장애가 실질적인 생장저하를 가져오며, 궁극적으로 물질대사의 최고 단계인 엽록소 특성이나 생장 또한 낮아지는 경향을 보여주었다. Unlike the seedling growth according to growth density per 1 ㎡ on Platanus orientalis demonstrated excellent increment in diameter at root collar and tree height from 49 trees/㎡, the treatment of higher growth density in diameter at root collar and tree height growth demonstrated decline tendency. This would be an important factor determining that a growth density largely affects on seedling growth and 49 trees/㎡ that has excellent growth in chlorophyll contents at 4.3 mg/gㆍwt displayed higher level of contents compare to 90 trees/㎡ at 2.9 ㎎/gㆍwt which decline in growth. Biomass, in the same manner to the growth feature also showed statistically significant difference in the 49 trees/㎡ treatment, showing higher biomass compare to other treated sections at 3.12±0.80 g. The tree showed a physiologically stable pattern of growth while demonstrating ultimately higher biomass through retaining appropriate space under the growth environment condition. We suggested that an obstacle in the appropriate space lower the actual growth and showed decrease tendency in growth and chlorophyll content feature which was the optimum stage of metabolism.

Longitudinal Standards for Height and Height Velocity in Korean Children and Adolescents: the Kangwha Cohort Study

채현욱,서일,권아름,김예진,김용혁,강대룡,김하얀,오선민,김현창,김덕희,김호성 대한의학회 2013 Journal of Korean medical science Vol.28 No.10

Longitudinal standards for height and height velocity are essential to monitor for appropriate linear growth. We aimed to construct standards in Korean children and adolescents through the population-based longitudinal Kangwha study. Our study was a part of a community-based prospective cohort study from 1986 to 1999 with 800 school children. Height and height velocity were recorded annually from age 6 until final height. Results were compared with cross-sectional data from the 2007 Korean National Growth Charts. Final height was 173.5 cm in boys and 160.5 cm in girls. Although final height was similar between longitudinal and cross-sectional standards, the mean height for age was higher in the longitudinal standard by 1-4 cm from age 6 until the completion of puberty. Using the longitudinal standard, age at peak height velocity (PHV) was 12 in boys and 10 in girls; height velocity at PHV was 8.62 cm/yr in boys and 7.07 cm/yr in girls. The mean height velocity was less than 1 cm/yr at age 17 in boys and 15 in girls. Thus, we have presented the first report of longitudinal standards for height and height velocity in
