In this study, we investigated the developmental characteristics and genetic diversity of seven populations of two-spotted crickets (Gryllus bimaculatus De Geer, 1773 (Orthoptera: Gryllidae)) raised in South Korea. Regarding the developmental characteristics of the species, we observed no statistically significant difference in the weight of the nymphs in the six populations we tested. After molting, although weight differences were observed between the populations in each stage of the developmental period, the average weight for each developmental stage was constant. We also analyzed mitochondrial COI gene sequences (DNA barcoding region) of the reared crickets collected from five insect farms and two national insect rearing facilities and the resultant sequences were analyzed together with the 12 sequences from foreign countries specimens obtained from public data. We detected six haplotypes from 111 specimens, indicating a low intraspecific genetic distance (~1.8%). The most dominant haplotype was overwhelmingly haplotype 1, which was found in all South Korean specimens and four specimens from China, Indonesia, and Germany. These findings indicate that the low genetic diversity of South Korean specimens can be explained by the fact that the G. bimaculatus population imported for feed from Japan in the early 2000s became a maternal group that spread throughout cricket farms in South Korea. In order to breed healthy cricket strains, it is necessary to increase genetic diversity by importing them from other countries through appropriate quarantine procedures.

This study investigated developmental trends and sex differences in the relation between children's self-esteem and relevant variables by proposing and testing the causal model. The 763 children who participated in the study were 3rd, 5th, and 7th grade students. Major findings were that physical appearance was the most powerful determinant of self-esteem. Students with high self-esteem were more learning oriented, used more motivational behaviors and had higher academic achievement. The findings from this analysis of the causal model revealed remarkable developmental differentiation and stability.

PURPOSE: The purpose of this study was first to develop a Korean version of pediatric functional muscle testing for children with a motor developmental disorder who have a communication problem and who are aged below five years, and also to verify the content validity. METHODS: First, the preliminary study was conducted to verify the reliability of pediatric functional muscle testing, developed by Venita in Korea. Based on the results of the study, the primary evaluation items were selected and modified. Second, the first test of content validity was conducted through a panel discussion, and a second investigation of content validity was carried out by utilizing the Item Content Validity Index (I-CVI). In this study, we selected only 0.78 or more items from I-CVI. RESULTS: Based on the results of the preliminary study, 19 primary evaluation items were selected. Based on the results of the first and second content validity tests, 15 tertiary evaluation items for the Korean version of pediatric functional muscle testing were determined. CONCLUSION: This study developed a new Korean version of pediatric functional muscle testing and suggested that it will be a useful tool to measure muscle strength for Korean children with a motor developmental disorder and a communication problem, aged below five years.

Purpose: The purpose of this study is to generate industrial insights for developing sports movie industry. Related studies are scare. Research design, data, and methodology: The study employed case study and selected typical case samples who seem informative about sport movie industry. The authors interviewed six experts who are experienced in sport movie and related academic sector. Interviews were audio-taped and the text were decoded by multiple reading. Through this process, the study categorized significant meanings and produced results. Interviewees reviewed again the final findings to confirm validity, which calls member check. Results: It was suggested that developmental factors of sports movie were the realization of realistic sports scenes by using technologies. Second, participants told that contents of sport movie need to reflect real stories and it should tell the stories. Regarding constraints of sport movies, movie producers feel difficulty to make scenes in that sports are inherently quickly performed. Another constraints are that production cost is expensive but audiences are barely attended. Conclusions: For promoting economic outcomes and developing sport movie industry, government needs to financially support related markets to support sport movie producers assisting them to concentrate their movie works. Future directions for related-studies were discussed.

Purpose: In this study, a Checklist for Infant and Child Developmental Screening (CICDS) was designed for use by primary pediatric health care providers to identify infants and children with developmental delays. Method: Each Item of the CICDS was constructed referring to existing tools. In 5 public health centers of B city, 500 infants and children were selected at the age of 2, 4, 6, 12, & 18 months and assessed between October and December 2006, CICDS and the Korea Denver II were compared to assesses the validity of the CICDS. Results: The CICDS consisted of 30 items in 4 areas; Personal-social, Fine motor-adaptive, Language, Gross motor. The results of the CICDS correlated significantly with the result of Korea Denver II at each month of age. (r=0.19; p<.01). Of the 500 infants and children, 148 were "suspect" for development delays (sensitivity of 96%, specificity 73%). On the CICDS, 74.6% of children received same result as Denver II. In discriminant analysis, 89.9% of children were identified correctly by CICDS (p<.01). Conclusion: CICDS could be a screening procedures to quickly and reliably identify infants with developmental delays. It also provides a mean of recording measurements of development characteristics.

Environmental conditions during early mammalian embryo development are critical and some adaptational phenomena are observed. However, the mechanisms underlying them remain largely masked. Previously, we reported that AQP5 expression is modified by the environmental condition without losing the developmental potency. In this study, AQP11 was examined instead. To compare expression pattern between in vivo and in vitro, we conducted quantitative RT-PCR and analyzed localization of the AQP11 by whole mount immunofluorescence. When the fertilized embryos were developed in the maternal tracts, the level of Aqp11 transcripts was decreased dramatically until 2-cell stage. Its level increased after 2-cell stage and peaked at 4-cell stage, but decreased again dramatically until morula stage. Its transcript level increased again at blastocyst stage. In contrast, the levels of Aqp11 transcript in embryos cultured in vitro were as follows. The patterns of expression were similar but the overall levels were low compared with those of embryos grown in the maternal tracts. AQP11 proteins were localized in submembrane cytoplasm of embryos collected from maternal reproductive tracts. The immune-reactive signals were detected in both trophectoderm and inner cell mass. However, its localization was altered in in vitro culture condition. It was localized mainly in the plasma membrane of the blastocysts contacting with external environment. The present study suggests that early stage embryo can develop successfully by themselves adapting to their environmental condition through modulation of the expression level and localization of specific genes like AQP11.

본 연구는 대학생들의 발달자산과 스트레스 및 위험행동의 관계를 구조적으로 살펴보는데 목적이 있다. 연구대상은 대학교 1학년부터 4학년 학생들 1023명이며, 측정도구는 발달자산 척도, 스트레스 척도, 위험행동 척도로 구성된 구조화된 설문지를 이용하였다. 자료 분석은 변인들의 정규분포, 다중공선성, 상관관계 및 구조방정식모형을 분석하였다. 연구결과 첫째, 외적자산이 위험행동에 미치는 영향은 유의미하지 않았으나, 스트레스에는 부적인 영향을 미쳤다. 내적자산은 스트레스 및 위험행동에 부적인 영향을 미쳤다. 둘째, 외적자산, 내적자산의 관계에서 스트레스의 매개효과를 검증한 결과 외적자산은 스트레스를 매개로 하여 위험행동에 미치는 부적인 영향이 유의미하였다. 내적자산도 스트레스를 매개로 하여 위험행동에 미치는 부적인 영향이 유의미하였다. 이러한 연구결과를 통해 대학생들의 발달자산은 스트레스의 증감에 따라 위험행동에 영향을 미칠 수 있으며, 특히 내적자산은 위험행동에 직접적으로 영향을 줄 수 있는 것으로 밝혀졌다. 이러한 연구결과를 통해 대학생들의 발달자산과 스트레스 및 위험행동이 관계가 있으며, 특히 대학생들의 스트레스 및 위험행동을 감소하기 위하여 내적자산 증진교육프로그램의 개발이 필요함을 시사하였다.
