Attention deficit hyperactivity disorder (ADHD) is a neurobehavioral developmental disorder characterized by a persistent pattern of inattention and/or hyperactivity, as well as forgetfulness, poor impulse control or impulsivity, and distractibility. The recommended evaluation includes documenting the type and severity of ADHD symptoms, verifying the presence of normal vision and hearing, screening for comorbid psychological conditions, reviewing the child's developmental history and school performance, and applying objective measures of cognitive function. Prevailing opinion characterizes ADHD as a disorder of executive function attributable to abnormal dopamine transmission in the frontal lobes and frontostriatal circuitry. A clearly defined etiology remains unknown, but studies suggest a strong genetic link. The aim of treatment is to decrease symptoms, enhance functionality, and improve well-being for the child and his or her close contacts. Stimulants remain the pharmacological agents of first choice for the management of ADHD, and psychosocial, behavioral and educational strategies that enhance specific behaviors may improve educational and social functioning in children with ADHD.

The present study examined preschooler's (3-5yrs) representation and evaluation skills in a puzzle completion task. The puzzle contained panels of four children dressed for each seacon and the key to success was using a body scheme to reconstruct the panels (head, torso, legs, feet and sky on top). Baseline data (Study 1) revealed a developmental pattern of increasing bydy scheme representation along with more careful attention to season consitent construction. Spontaneous verbalization also shifted from more guiding statements (where'the head?) to move evaluative statements (this isn't right). Study 2 examined different intervention techniques for increasing representation (verbal laveling) and evaluative processes (error detection practice), along with a control group that had unassisted practice. Three year olds benefited from verbal labeling, four year olds from both types of training. Verbalizations also showed appropriated shifts toward increasing evaluation, particularly for the older children. These findings are discussed in terms of a developmental hypothesis that representation precedes evaluation skills and that training techniques should take into account the relative balance between representation and evaluation skills in the individual for the task at hand.

uftraspirocle (usa) gene product (Uspl is a member of the superfamilv of steroid hormone receptors in Drosophila melonogaster which mediate the hormone action by heteromerization with ecdvsone receptor (EcR). Based on the genetic and molecular characterization of usp, it has been proposed that Usp funtions in at least three significant developmental pathway: embrvogenesis, eve morphogenesis, and female reproduction. In this study, the expression patterns of Usp were investigated by immunohistochemistrv in individual tissues from diHernt developmental stases of Drosophila. Usp is localized in the nucleus with ubiquitous distribution throughout development. Usp expression is detected throughout embrvogenesis. Usp is expressed in imaginal and lanral tissues from late third instar 18nra. The expression pattern of Usp is overlapped by those of EcR. Also Usp is expressed in differentiating adult reproductive organs. This result suggests that Usp is not a transcriptional regulatory factor modulating hormonal response during development, but also play some roles in female and male reproduction of Drosophila.

The purpose of the study is to investigate how childhood attachment and autonomy explain the gender differences in adulthood heterosexual love styles. The study examines (1) the gender differences in childhood attachment and autonomy and adulthood heterosexual love relationships, (2) the relationship between childhood attachment and autonomy in relation to mother, and love styles in adulthood among men and women. 405 married or unmarried men and women participated in a questionnaire study. Such statistic analyses are engaged for this study as cross-tabulation analysis, and one-way ANOVA. The key findings of the study are that the relationships of childhood developmental pattern of attachment and autonomy to adulthood heterosexual love styles differ between men and women. That is, developmental patterns of childhood attachment and autonomy to mother operate as a vulnerability factor in establishing adulthood love relationship, whereas childhood experiences do not explain adulthood love among women. These gender differences are discussed in theoretical contexts which explain gender-differentiated process of separation from mother during childhood.

As society and culture becomes complicated and diverse, so do the ensuing problems. The symptoms from the stress there was mainly focused on the adult group, however, now, they are shown in children. So the play therapy attracts attention as a way to cure stress. This study is intend to analysis an environment of play therapy space which would play an active role during treatment through the understanding of children's playing behavior. Disable children's playing therapy and pattern should be considered in the playing environmental design, and their feelings also need to be considered. The cozy and relaxed environment is important to children, so that they can have a natural interaction with the environment during the therapies. Output the factor of environment for play therapy and suggest the space of play therapy which fit on it.

Objectives : This paper examines the medical treatise and treatment methods of Zhang Jiebin on the depressive pattern, for clinical application today. Methods : The Zazhengmo/Yuzheng chapter of the Jingyue Quanshu, related texts and annotations of the Huangdineijing, and related contents among the medical texts of the JinYuan masters were analyzed. Developmental process of the medical theories were compared and examined. Results : Zhang focused on the mechanism in which emotion affects Qi leading to a disease state, and categorized Yu[鬱, depressed state] into three: anger depression, contemplative depression and comprehensive depression. The concept of the Five Depressive Patterns and its treatment from the Huangdineijing·Suwen which was considered as excess pattern was expanded to include deficiency pattern based on comparison with annotations of Wangbing, Hwashou, and Wang Andao. Treatment methods centered on purging was also expanded to include tonifying to restore the damaged Jing Qi. The depressive patterns anger depression, contemplative depression and comprehensive depression were subdivided according to excess and deficiency, for which formulas such as Shenxiangsan, Shoupijian, Guipitang were suggested. As the depressive pattern is caused by emotions and thus the Heart, the Yiqingbianqi method that directly deals with emotions was suggested. Zhang adopted Zhu Zhenheng's opinion which expands the category of Yu, and in the perspective of excess/deficiency, it is most similar to that of Li Dongyuan. Conclusions : Before Zhang, the depressive pattern was discussed in terms of it being excess pattern. However, Zhang's discussion on depressive pattern based on anger depression, contemplative depression and comprehensive depression focuses on emotional stagnation while suggesting the possibility of deficient stagnation, expanding previous understanding. In terms of treatment, tonifying methods for deficiency pattern was added, while consideration of emotion itself became necessary in treatment.

Fish larvae are immediately exposed to microbes from hatching to maturation of their lymphoid organs, therefore effective innate mechanisms is very important for survival in such an environment. The key component of innate immune system, C3 is central protein of all activation pathways of the complement system, leading to inflammatory reactions, such as opsonisation, chemotaxis, and cell lysis of pathogens. Although, innate mechanisms is essential for survival in the early stage of development, little is known about defence mechanisms. In this study, the alignment analysis showed that amino acid sequence of C3 from olive flounder liver EST homologous to other known C3 sequences with 73-99% identity. Also, we examined the tissue distribution of olive flounder C3 and analyzed expression pattern from the fertilized egg until 28 days post hatching. As a result, olive flounder C3 mRNA was expressed only in the liver and the mRNA level more increased as developmental proceed during the early stage. These results may suggest that olive flounder C3 plays an important function in the early immune response of olive flounder larvae.

Adaptive development of early stage embryo is well established and recently it is explored that the mammalian embryos also have adaptive ability to the stressful environment. However, the mechanisms are largely unknown. In this study, to evaluate the possible role of aquaporin in early embryo developmental adaptation, the expression of aquaporin (AQP) 5 gene which is detected during early development were examined by the environmental condition. To compare expression patterns between in vivo and in vitro, we conducted quantitative RT-PCR and analyzed localization of the AQP5 by whole mount immunofluorescence. At in vivo condition, Aqp5 expressed in oocyte and in all the stages of preimplantation embryo. It showed peak at 2-cell stage and decreased continuously until morula stage. At in vitro condition, Aqp5 expression pattern was similar with in vivo embryos. It expressed both at embryonic genome activation phase and second mid-preimplantation gene activation phase, but the fold changes were modified between in vivo embryos and in vitro embryos. During in vivo development, AQP5 was mainly localized in apical membrane of blastomeres of 4-cell and 8-cell stage embryos, and then it was localized in cytoplasm. However, the main localization area of AQP5 was dramatically shifted after 8-cell stage from cytoplasm to nucleus by in vitro development. Those results explore the modification of Aqp5 expression levels and location of its final products by in vitro culture. It suggests that expression of Aqp5 and the roles of AQP5 in homeostasis can be modulated by in vitro culture, and that early stage embryos can develop successfully by themselves adapting to their condition through modulation of the specific gene expression and localization.

We investigated the developmental characteristics and life cycle of the lawn cutworm, Spodoptera depravata (Lepidoptera: Noctuidae), which is one of the most important pests causing economic damage in grass production. For larval culture, we provided the zoysiagrass at $25^{\circ}C$ and $60{\pm}5%$ humidity. The durations of the developmental stages were as follows: $4.11{\pm}0.19$ days for eggs, $25.17{\pm}3.02$ for larvae, $8.80{\pm}0.28$ for pupae, and $7.57{\pm}0.95$ for adults. We grew the larvae to the 7th instar stage, unlike previous studies, in which it was assumed that the 6th instar was the final age. There was a significant positive correlation between the body length and head capsule width of each instar larvae. In terms of morphology, the eggs changed from light green immediately following oviposition to black as they developed, and the grass-fed larvae changed from light yellow immediately after hatching to green as development continued. We observed a pattern of black spots at regular intervals on the dorsal sides of the abdomens of the final instar larvae. Furthermore, we detected two notable designs on the dorsal side of the front of the head. The pupal colors changed from light brown and green immediately after pupation, to dark brown as the pupal cuticle hardened. The wingspans of the adults were similar in both sexes. However, the forewings of the males had obvious outer lines and eyespots with dark gray-brown backgrounds, whereas the corresponding features on the female forewings were less obvious. The oviposition preperiod was 2.11 days, the oviposition period was 4.2 days, the average fecundity per female was approximately 341 eggs, and the hatching rate was approximately 76.1%.

Reproductive traits of Palaemon gravieri such as embryo size, number of embryo (fecundity), incubation period, larval development mode, larval development period, larval survival and larval growth were described and compared to analyze the correlation among those traits. Embryo volume is a primary factor determining other ensuing reproductive features. Egg volume was $0.042mm^3$ in the first developmental stage. Embryo volume in P. gravieri was comparatively small which is indicative of great number of embryo (y = 3.0161x + 0.0185 $R^2$ = 0.74 positive isometric relationship) and relatively long incubation period. Larvae survived from zoea 1 to post-larvae and it took 45 days at $22^{\circ}C$. Survival rate of the larvae was rather great in the early stage and thereafter steadily decreased. Daily growth rate of larvae in P. gravieri at $22^{\circ}C$ was 0.0195 mm on average. They grew steadily as time went by. Incubation period was between 10-14 days at $22^{\circ}C$. Larval development mode was almost complete planktotrophic. PNR (point of no return) appeared to be the third day on average. Survival rate of larvae without feeding declined rapidly between 3 and 4 days. Larval development period and stage frequency were 23-30 days and 11 stages which imply prolonged larval period and high mortality. The pattern of brood production followed fast successive parturial pattern. Most ovigerous female had mature ovary when they performed parturial molt soon after hatching (larval release).
