  • Schizophyllum commune has emerged as the most promising model mushroom to study developmental stages (mycelium, primordium), which are two primary processes of fruit body development. Long non-coding RNA (lncRNA) has been proved to participate in fruit development and sex differentiation in fungi. However, potential lncRNAs have not been identified in S. commune from mycelium to primordium developmental stages. In this study, lncRNA-seq was performed in S. commune and 61.56 Gb clean data were generated from mycelium and primordium developmental stages. Furthermore, 191 lncRNAs had been obtained and a total of 49 lncRNAs were classified as differently expressed lncRNAs. Additionally, 26 up-regulated differently expressed lncRNAs and 23 down-regulated between mycelium and primordia libraries were detected. Further, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that differentially expressed lncRNAs target genes from the MAPK pathway, phosphatidylinositol signal, ubiquitin-mediated proteolysis, autophagy, and cell cycle. This study provides a new resource for further research on the relationship between lncRNA and two developmental stages (mycelium, primordium) in S. commune.

  • The purpose of this study was to examine the screening and its validation of children with language developmental delay in child care and education centers, the response of parents with children with language developmental delay and the assistance needs of child care and education teachers for those children. Teacher interview with semi-structural method, transcription and content analysis method were used. The subjects in this study were 13 teachers and 30 infants and toddlers with language developmental delay in 10 child care and education centers in Seoul. The findings of the study were as follows: First, the child care and education teachers screened children with language developmental delay in their classes based on their verbal characteristics and maladjusted behavior. Their screenings were turned out correct. Second, as for the response of parents, the parents who had children with language developmental delay were indifferent, were aware of the fact in advance or asked the teachers for counseling on their children's language developmental delay. Third, the teachers couldn't provide the appropriate supports for the children in needs. Fourth, regarding the assistance needs of the child care and education teachers, they called for assistance from specialists and professional institutions, and wanted to receive education on language development. Besides, they asked for relevant supporting materials and screening criteria, and considered it necessary to reduce the ratio of teacher to children.

  • The purpose of this study is to investigate the influence of the mentoring function and mentor trust on the intention to reparticipate in the mentoring program, focusing on university students in fashion related departments. To achieve the purpose, research was conducted through a survey questionnaire. The questionnaire data from 223 university students in fashion related departments who experienced mentoring programs were analyzed. SPSS 18.0 and AMOS 7.0 statistical packages were used to investigate a structural model and test research hypotheses. The results derived from the analysis of the questionnaire survey were summarized as follows. First, the result showed that the mentoring function was composed of three factors: a sensitivity developmental function, psychosocial function, and fashion career developmental function. Second, the sensitivity developmental function, psychosocial function, and fashion career developmental function positively affected mentor trust. Third, the sensitivity developmental function positively affected the intention to reparticipate in the mentoring program, while the psychosocial function and fashion career developmental function did not influence the intention to reparticipate in the mentoring program. Fourth, mentor trust positively influenced the intention to reparticipate in the mentoring program. The results of the current study would be useful for the professor and university administrator who would like to establish a mentoring program in a fashion related department, by exploring the relation of mentoring function, mentor trust and the intention to reparticipate in the mentoring program.

  • BACKGROUND/OBJECTIVES: Iron deficiency in early life is associated with developmental problems, which may persist until later in life. The question of whether iron repletion after developmental iron deficiency could restore iron homeostasis is not well characterized. In the present study, we investigated the changes of iron transporters after iron depletion during the gestational-neonatal period and iron repletion during the post-weaning period. MATERIALS/METHODS: Pregnant rats were provided iron-deficient (< 6 ppm Fe) or control (36 ppm Fe) diets from gestational day 2. At weaning, pups from iron-deficient dams were fed either iron-deficient (ID group) or control (IDR group) diets for 4 week. Pups from control dams were continued to be fed with the control diet throughout the study period (CON). RESULTS: Compared to the CON, ID rats had significantly lower hemoglobin and hematocrits in the blood and significantly lower tissue iron in the liver and spleen. Hepatic hepcidin and BMP6 mRNA levels were also strongly down-regulated in the ID group. Developmental iron deficiency significantly increased iron transporters divalent metal transporter 1 (DMT1) and ferroportin (FPN) in the duodenum, but decreased DMT1 in the liver. Dietary iron repletion restored the levels of hemoglobin and hematocrit to a normal range, but the tissue iron levels and hepatic hepcidin mRNA levels were significantly lower than those in the CON group. Both FPN and DMT1 protein levels in the liver and in the duodenum were not different between the IDR and the CON. By contrast, DMT1 in the spleen was significantly lower in the IDR, compared to the CON. The splenic FPN was also decreased in the IDR more than in the CON, although the difference did not reach statistical significance. CONCLUSIONS: Our findings demonstrate that iron transporter proteins in the duodenum, liver and spleen are differentially regulated during developmental iron deficiency. Also, post-weaning iron repletion efficiently restores iron transporters in the duodenum and the liver but not in the spleen, which suggests that early-life iron deficiency may cause long term abnormalities in iron recycling from the spleen.

  • This study aims to explore how the transformational leadership (consisting of three factors"charisma, individualized consideration, and intellectual stimulation) and the organizational culture (typified by developmental, rational, consensual, and hierarchical culture) are related to the organizational effectiveness (consisting of job satisfaction, organizational commitment, and intention to leave a job) of dental clinics. We found the following empirical results through a survey of 378 persons who work in dental clinics. Firstly, the respondents acknowledged charismatic leadership as the typical type of leadership ; as for organizational culture, a culture of consensus is recognized as the representative type. Secondly, transformational leadership has different effects according to the type of organizational culture: a positive influence in developmental and rational cultures, but a negative influence in consensual and hierarchical cultures. Thirdly, developmental culture has proven to be the most suitable for increasing job satisfaction and organizational commitment. The developmental, rational, and consensual cultures have all contributed to reducing intention to leave among clinic staff, whereas in the hierarchical culture, intention has been elevated. Fourthly, transformational leadership has a positive effect on the job satisfaction and organizational commitment; the intent to leave has been lessened under individualized consideration and charismatic leadership, but has been increased under leadership of intellectual stimulation. Fifthly, it is consideration and charisma that help to increase organizational effectiveness. These influences will become more effective through a developmental culture. Based on the above empirical results, we propose practical measures to improve the organizational effectiveness of clinics, in particular dental clinics. In order to build developmental culture, the doctor (manager) should produce an atmosphere in the clinic in which staff members are able to create and jointly own ideas and then promote awareness of staff participation. Additionally, in order to bring leadership of charisma and consideration into full play, the doctor should shape a relationship of mutual trust mainly by recognizing and praising the work of clinic staff. Finally, the doctor needs to acknowledge that organizational effectiveness can be significantly improved by increasing the transparency of the business.

  • The study was carried out to investigate the effects of morphology, reproductive cycle, incubation time and activation of oocytes on in vitro maturation of cat oocytes and development of IVM/IVF embryos. The results were summarized as follows: 1. When recovered from ovaries collected at different stages of the reproductive cycle (inactive, follicular and luteal stage), the developmental rates of oocytes to GV and MI stage were 72.5% and 27.5%, 57.5% and 7.5%, 62.5% and 17.5%, respectively. 2. The developmental rates of oocytes with cumulus cells to GV and MI stage in different conditions of incubation (5% $CO_2$ , 95% $O_2$ and 10% $CO_2$, 90% $O_2$) were 70.0% and 27.5%, 52.5% and 20.0%, 55.0% and 12.5%, respectively. 3. The developmental rates to GV and MI oocytes when cultured at different time of incubation (17∼20, 21∼24, 25∼28 and 29∼32 h) were 67.5% and 20.0%, 67.5% and 30.0%, 62.5% and 22.5%, 65.0% and 15.0%, respectively. 4. The fertilization and cleavage rates of freshly collected oocytes with and without cumulus cells were 72.5% and 25.0%, 37.5% and 7.5%, respectively. The rates were greater in oocytes with cumulus cells than those without cumulus cells. 5. The fertilization and cleavage rates of oocytes recovered from ovaries collected at different stages of the reproductive cycle (inactive, follicular and luteal stage) were 75.0% and 25.0%, 40.0% and 7.5%, 50.0% and 15.0%, respectively.

  • The purpose of this study is to analyze the general characteristics, effect size, and qualitative indicators of self-advocacy studies of people with developmental disabilities published in domestic academic journals and theses. For this purpose, among a total of 2153 papers related to self-advocacy published from 2000 to 2023, 41 studies with developmental disabilities as the keyword were selected, and the specific research results are as follows. Based on the results of this study, when developing a language intervention program related to self-advocacy for people with developmental disabilities, it is recommended to develop an intervention program based on the number of sessions of 10-19 in a learning situation with 20-30 people in adolescents and adults, or during the transition period. There are many studies limited to educational aspects such as special education and integrated education, and by applying this, it is hoped that a self-advocacy language intervention program will be developed at the level of language rehabilitation that can effectively and sophisticatedly assert self-assertion and self-rights after experiencing difficulties in communication.

  • Purpose: This study investigated the prevalence of developmental and acquired pathologic conditions associated with impacted third molars (3Ms) in a Southern Brazilian population and evaluated whether demographic and tooth characteristics were correlated with the presence of bone or tooth lesions. Materials and Methods: Panoramic radiographs were assessed for developmental (bone-related) or acquired (tooth-related) pathoses associated with impacted upper or lower 3Ms. Data on tooth positioning, tooth development, and patient demographics were collected. A trained, calibrated postgraduate student evaluated all images. Binary and multivariate logistic regression models were used to assess associations between outcomes and the demographic and radiographic variables. The threshold for statistical significance was set at 5% (P<0.05). Results: The sample comprised panoramic radiographs from 2054 patients, predominantly female (59.2%), with a mean age of 27.2±11.5 years. Overall, 4066 impacted 3Ms were evaluated, revealing 471 (11.6%) developmental and 710 (17.5%) acquired pathoses. Among the developmental pathoses, 460 (95.2%) were indicative of dentigerous cysts. Male sex, lower 3M location, vertical or distoangular positioning, and incomplete root formation were associated with an elevated likelihood of developmental pathology. Lower tooth position, complete root formation, and partial eruption were linked to an increased probability of an acquired pathology in the third or second molar. Conclusion: The prevalence of pathologic conditions associated with impacted 3Ms was low. Male sex, lower 3M placement, horizontal or distoangular positioning, and incomplete root formation were associated with developmental pathoses, while lower tooth position, complete root formation, and partial eruption were related to acquired pathoses.
