The purpose of this study is to examine the effects of sensory integration training on children with developmental delays. To achieve this goal, an educational experiment is conducted in five main areas: gross motor ability, fine motor ability, adaptive ability, language and social ability in children with developmental delay. The study subjects were children with developmental delays aged 3-6 years diagnosed at Beijing Institute of Pediatrics and Beijing Medical University and received sensory integration intervention and homebased training at the Golden Rain Forest Beijing Tongzhou Center from 2018 to 2021. According to the purpose of the analysis, the data collected are subjected to descriptive statistics using SPSS 21.0 statistical program, Two-way MANOVA analysis, and data analysis method of multivariate analysis is used to process the collected data. In addition, a total of 39 subjects were selected, including 19 children who received sensory integration training and 20 children who only received family training. The results show that the sensory integration training group outperformed the home training group in all aspects and developmental quotient, but the home training group also showed higher levels of significance for improvements in gross motor, fine motor and developmental quotient.

Let N be a normal subgroup of a path-connected topological group (G, $t$). In this paper, the authors consider the existence of path-connectedness in refined topologies in order to address the property of maximal path-connectedness in topological groups. In particular, refinements on $t$ and refinements on the quotient topology on G/N are studied. The preservation of path-connectedness in extending topologies and translation topologies is also considered.

Let G be the 3-dimensional Heisenberg group. A discrete subgroup of Isom(G), acting freely on G with non-compact quotient, must be isomorphic to either 1, Z, Z2 or the fundamental group of the Klein bottle. We classify all discrete representations of such groups into Isom(G) up to affine conjugacy. This yields an affine calssification of 3-dimensional non-compact infra-nilmanifolds.

We study some properties of intuitionistic fuzzy normal subgroups of a group. In particular, we obtain two characterizations of intuitionistic fuzzy normal subgroups. Moreover, we introduce the concept of an intuitionistic fuzzy coset and obtain several results which are analogous of some basic theorems of group theory.

In this paper, we study the sequentially open and closed subsets of sequential topological groups determined by sequentially continuous group homomorphism. In particular, we investigate the sequentially openness (closedness) and sequentially compactness of subsets of sequential topological groups by the aid of sequentially continuity, sequentially interior or closure operators. Moreover, we explore subgroup and sequential quotient group of a sequential topological group.

This study aimed to investigate the relationship between eating speed and nutritional status among Korean high-school students using Nutrition Quotient for Korean Adolescents (NQ-A). In this study, a questionnaire survey was conducted in 453 high-school students (227 boys and 226 girls) from September 2019 to October 2019 in Chungbuk area. Based on the self-reported speed of eating data, subjects were classified into a fast group (n=180), a medium group (n=184), and a slow group (n=89). NQ-A scores for each group were measured in each speed group. In the environment section, girls showed a significant difference in usage time of electronic devices, such as TVs and smartphones: the fast group spent significantly more time than the medium group (p=0.035). In the practice section, among boys, the slow group had significantly higher scores for washing hands before eating than the medium and the fast groups (p=0.022). This study suggested that eating speed of high school students is associated with health-related environment factor and practice factor of NQ-A, such as time spent on smart devices or washing hands before eating. The study results can provide baseline data for nutrition education on health management of high school students.

목적 : 발달지연 아동을 대상으로 Ayres 감각통합중재를 적용하여 감각처리능력과 운동발달에 미치는 영향을 알아보고자 하였다. 연구방법 : 만 3-5세의 발달지연 아동을 대상으로 실험군 9명과 대조군 8명이 본 연구에 참여하였고 Short Sensory Profile(SSP), Peabody Developmental Motor Scale-2(PDMS-2)를 사용하였다. 실험군은 Ayres의 중심원리에 따른 개별 감각통합치료를 40분씩, 주 2회, 8주간 총 16회기를 실시하였다. 분석은 SPSS 24.0 의 카이스퀘어 검정, 맨휘트니 U검정, 윌콕슨 부호순위 검정, Cohen's d 검정으로 하였다. 연구결과 : Ayres의 감각통합중재를 실시한 실험군은 중재를 실시하지 않은 대조군에 비해 감각처리능력은 전체 점수와 움직임 민감성, 청각 여과하기, 낮은 에너지/허약함에서 통계적으로 유의한 차이가 나타났다(p<.05). 실험군과 대조군의 운동발달은 대근육운동발달지수, 소근육운동발달지수, 전체운동발달지수 모두 통계적으로 유의한 차이가 나타났다(p<.05). 결론 : Ayres의 감각통합중재는 발달지연 아동의 감각처리능력과 운동발달에 긍정적인 영향을 미쳤다.

PURPOSE. This study investigated the influence of bone quality and surgical technique on the implant stability quotient (ISQ) value. In addition, the influence of interfacial bone quality, directly surrounding the implant fixture, on the resonance frequency of the structure was also evaluated by the finite element analysis. MATERIALS AND METHODS. Two different types of bone (type 1 and type 2) were extracted and trimmed from pig rib bone. In each type of bone, the same implants were installed in three different ways: (1) Compaction, (2) Self-tapping, and (3) Tapping. The ISQ value was measured and analyzed to evaluate the influence of bone quality and surgical technique on the implant primary stability. For finite element analysis, a three dimensional implant fixture-bone structure was designed and the fundamental resonance frequency of the structure was measured with three different density of interfacial bone surrounding the implant fixture. RESULTS. In each group, the ISQ values were higher in type 1 bone than those in type 2 bone. Among three different insertion methods, the Tapping group showed the lowest ISQ value in both type 1 and type 2 bones. In both bone types, the Compaction groups showed slightly higher mean ISQ values than the Self-tapping groups, but the differences were not statistically significant. Increased interfacial bone density raised the resonance frequency value in the finite element analysis. CONCLUSION. Both bone quality and surgical technique have influence on the implant primary stability, and resonance frequency has a positive relation with the density of implant fixture-surrounding bone.
