  • Objectives The study was designed to find out the relationships between low weight and growth, skeletal maturity among children by analyzing body composition and bone age. Methods Subjects were composed of 336 children from six years to seventeen years of age, without any other diseases related to growth, who visited the department of oriental pediatrics East West Neo Medical Center at Kyung Hee University and were measured their body composition and bone age. Results There were significant correlations between decreasing of RH-MPH(%) and low weight. 1. As obesity index decreased, the RH-MPH was also decreased. 2. The RH-MPH(%) of the low weight group according to the obesity index classification was significantly decreased than that of the normal weight group. 3. The skeletal maturity was more decreased in the low weight group. However, the differences between the two group was not significant. 4. The RH-MPH(%) was increased in children who developed secondary sexual character. Skeletal maturity was decreased in children who developed secondary sexual character. 5. The RH-MPH(%), and skeletal maturity was not significantly different between males and females. 6. Only in the case of children without development of secondary sexual character, low weight caused significant RH-MPH(%) decrease. Conclusions Low weight children might be smaller than what it supposed to be. Also, low weight could affect body development more to the children than to the teenager.

  • We investigated the maturity and spawning dynamics of chub mackerel Scomber japonicus in Korean waters using samples collected by a large purse seine fishery from January 2013 to December 2017. We analyzed sex ratio, monthly maturity stage, gonadosomatic index (GSI), Fulton's condition factor (K), and fork length at 50% group maturity. Spawning occurred from March to June, with a peak in May. We detected a significant difference in sex ratio (χ2 test, P<0.05). The relationship between fork length and body weight was expressed as BW=0.0025FL3.4693. We estimated 50% group maturity at a female fork length of 29.3 cm.

  • This study was carried out to classify Korean soybean varieties base on maturity group (MG) and to find character relationships according to planting date for high quality soybean seed production adapted to early season cultivation environment of Miryang. Results of maturity grouping of Korean soybean varieties showed that Keunol (3 cultivars), belonged to Group 0; Seonnok and Danmi in Group II, Shinrok in Group III, Seonyu (17 cultivars), in Group IV, Taekwang (44 cultivars) in Group V, Daewon (25 cultivars) in Group VI, and Kwangdu and Keumdu in Group VII. Agronomic characteristics of 100 soybean varieties were compared based on MG, cultivation year and seeding date. Soybean varieties belonging to the MG $VI{\sim}VII$ showed longer days to flowering and growth period, high lodging density and higher yield. Seed quality analysis revealed that as maturity was delayed, seed weight becomes heavier while seed cracks become abundant. In addition, occurrence of purple seed and phomopsis were higher in MG $0{\sim}III$. Protein content was higher in MG $0{\sim}III$, and isoflavone content was higher as maturity was delayed. On the other hand, lipid content was generally similar across MGs. Correlation analysis of major agronomic characters showed positive relationships between days to flowering and growth days, seed weight and lodging in MG $IV{\sim}V$, seed crack and growth days in MG $0{\sim}III$, seed crack and days to flowering in MG $IV{\sim}V$ and MG $VI{\sim}VII$, seed crack and lodging in MG $IV{\sim}V$ and MG $VI{\sim}VII$, seed crack and seed weight in MG $IV{\sim}V$ and MG $VI{\sim}VII$, purple seed and growth days in MG $IV{\sim}V$, purple seed and seed weight in MG $VI{\sim}VII$, phomopsis and growth days in MG $IV{\sim}V$ and MG $VI{\sim}VII$, and phomopsis and purple seed in MG $IV{\sim}V$ and MG $VI{\sim}VII$. In contrast, a negative relationship was observed between seed weight and lodging in MG $0{\sim}III$. Correlating yield and major characters revealed negative relationships between days to flowering and growth days in MG $0{\sim}III$ and MG $IV{\sim}V$, whereas positive relationships were obtained on MG $VI{\sim}VII$ seeded on April 30. Lodging, seed weight and seed crack were all negatively correlated with yield in the MG $IV{\sim}V$ and MG $VI{\sim}VII$. Soybean cultivars identified as adaptable to early season planting for production of high quality soy curd and fermented soybean paste were Seonyu, Kwangdu, and Soho while those suited for the manufacture of soybean sprouts were Sobaeknanul, Kwangan, Sowon, and Bosuk. Geomjeong 2 chosen as best for mixing with rice.

  • This study investigated purplish Washington clam, Saxidomus purpuratus on its gonadal development, reproductive cycle and shell length (age) at 50% female group maturity from January to December 2011 in Jinhae Bay, Korea. This species is dioecious. The gonad index (GI) began to increase in January, reached the maximum value in May and to decrease in June, reached the minimum value in September then to increase slowly in October again. The reproductive cycle of the clams can be divided into five successive stages: the early active stage (Ea, from February to March), the late active stage (La, from January to March and October to December), the ripe stage (R, from January to May), the spawning stage (S, from June to December) and the degenerative and inactive stage (Ia, from January to February and November to December). The spawning periods were from June to December and the main spawning periods were from July to October. The shell length at 50% female group maturity (SL50) was estimated to be 63.6 mm, which can be converted as sexual maturity age of 2.2 year.

  • 패류 인공종자생산에서 모패관리의 중요성이 커져가고 있으며 최적의 모패 관리 조건과 원하는 시기에 종자생산을 할 수 있는 성숙유도 조건을 구명하는 하는 것이 매우 중요하기 때문에 본 연구에서는 왕우럭 조개의 모패관리 최적조건과 성숙 촉진을 위한 가온 효과를 조사하였다. 모패관리는 실내사육에 비하여 실외사육이 비만도와 생존율 측면에서 더 효과적인 것으로 나타났으며 관리 측면에서도 인위적인 먹이생물 공급이 없으며 자연환경 조건에서 사육하기 때문에 관리가 수월하다는 장점이 있는 것으로 나타났다. 그리고 동계가온을 통한 성숙촉진 유도는 비만도와 생식소 관찰 등을 통하여 수온 18℃ 이상에서 2개월 정도 사육하였을 경우 성성숙이 이루어지는 것으로 나타나 성숙관리가 다른 패류에 비해 용이하다는 것을 알 수 있었다.

  • Purpose: The aims of this study were to evaluate effects of massage therapy and the attachment promotion program with autistic children. Method: A quasi-experimental design was conducted with a convenience sample of 44 autistic children. The experimental group (n= 23) attended the massage therapy and the attachment promotion program for 4 months. The control group (n=21) only had the attachment promotion program. Measurements were made twice for both groups using the social maturity scale and child autism rating scale. Recording of mother-child attachment was done for 15 minutes in only the experimental group twice using video equipment. Results: After 4 months of interventions, there was significant difference on social maturity (F=9.01, p=.005) between the groups. However, there was no significant difference on CARS ((F=2.47, p=.124). The total scores of mother-child attachment between pre- and post-interventions showed a significant difference (Z=-3.42, p=.001). Conclusion: The results showed that massage therapy and the attachment promotion program might be an effective way for providing a chance to increase social maturation and to increase attachment between mother and autistic child.

  • Objectives The purpose of this study is to evaluate the current growth via Growth indices, Obesity indices, Metabolic risk factors of Multicultural Families' Children in Dae-jeon area. Methods 5 to 12 year old children from 56 multicultural families were enrolled in this study, and were examined their bone age and body composition, and have received blood tests. Results 1. In Growth indices, average height percentile was $53.64{\pm}25.59%$. The AHP and MPH respectively, were converted into 20 years old adult height percentile, AHP of a girls was 40 percentile and MPH was 19 percentile, AHP of boys was 57 percentile and MPH was 21 percentile. 2. In Obesity indices, average of BMI pecentile was $44.16{\pm}29.52$; low-weight group (6 boys, 4 girls), normal-weight group (20 boys, 18 girls), over-weight group (8 girls). Average PWH was $100.51{\pm}15.66%$; low-weight group (9 boys, 5 girls), normal-weight group (14 boys, 15 girls), over-weight group (3 boys, 5 girls), obesity group (5 girls). 3. The results of the relationship between Growth indices and Obesity indices, 1) As RH percentile in boys was increased, skeletal maturity, AHP and AHP-MPH were also increased. Similarly, as RH percentile in girls was increased, skeletal maturity, AHP and AHP-MPH were also increased. 2) As skeletal maturity in boys was increased, BMI percentile was also increased. As skeletal maturity in girls was increased, AHP-MPH was decreased but had no significant differences. Conclusions Current growth of children in multicultural families was above the average when compared to that of average children in the same age. It was predicted that the boys' height were still above the average adult height, but the girls' height were below the average. Also this study showed that girls were more prone to be overweight than boys, thus requiring more intensive management and training in regards to eating habits and exercise.
