Objective : The purpose of this study was to investigate the effect of Ayres's sensory integration (ASI) intervention on the sensory processing ability and motor development in children with Developmental Delay. Methods : 9 children in the experimental group and 8 children in the control group participated in this study for Developmental Delay children aged 3-5 years. For research tool, the Short Sensory Profile (SSP), Peabody Developmental Motor Scale-2 (PDMS-2) are used. In the experimental group, individual sensory integration therapy according to principle of ASI was performed for twice a week, 40 minutes, and 16 times for 8 weeks. Methods for the data analysis included Mann Whitney U test, Chi-square test, Wilcoxon's signed rank test, Cohen's d test of SPSS 24.0. Results : In the ASI Intervention group, the sensory processing ability showed statistically significant difference in total score, movement sensitivity, auditory filtering and low energy/weak compared to the control group without ASI intervention (p<.05). In the ASI Intervention group, the motor development showed statistically significant difference in Gross Motor Quotient, Fine Motor Quotient and Total Motor Quotient compared to the control group without ASI intervention (p<.05). Conclusions : In this study, ASI intervention had a positive effect on the sensory processing and motor development in children with Developmental Delay.

The Gilan-Cheongsong area, which is in contact with Yeongyang and Uiseong Blocks of Gyeongsang Basin, Korea, consists of Precambrian metamorphic rocks, Triassic Cheongsong granite, Cretaceous sedimentary rocks(Iljik, Hupyeongdong, Jeomgok Formations), and Cretaceous igneous rocks(andesite, quartz porphyry, felsite). In this area are developed faults trending in (W)NW, NNW, ENE, NS, (N)NE directions which are representative in the Gyeongsang Basin. We analyzed the geometric and kinematic characteristics of fracture systems to inquire into movement history and sense of these faults in this area. This study suggests that these faults were mainly strike-slip movement. The orientations of fracture sets show ENE, NNW, (W)NW, (N)NE, NS in descending order of frequency. Their prolongation presents (W)NW, NNW, ENE, (N)NE, NS in descending order of predominance, and also agrees with that of faults in this area. The development sequence and movement sense of fracture sets are summarized as follows; (1) (W)NW: dextral shearing $\rightarrow$ (2) (W)NW and NNW: conjugate shearing(the former: dextral, the latter: sinistral) $\rightarrow$ (3) NNW: dextral shearing $\rightarrow$ (4) (W)NW: sinistral shearing $\rightarrow$ (5) ENE: dextral shearing $\rightarrow$ (6) ENE and NS: conjugate shearing(the former: sinistral, the latter: dextral) $\rightarrow$ (7) (N)NE: sinistral shearing, and this result is closely associated with the development sequence and movement sense of faults developed in this area.

Purpose : This study aims to identify changes in the visuomotor coordination and fine motor coordination functions caused by the use of a task-oriented intervention in a child with developmental delay. Methods : The participant, who was a 6-year-old girl, was not diagnosed but showed a developmental delay in overall function. The study period was February 5, 2021, to June 4, 2021, and a single-subject A-B study design was used. The baseline (A) was initially evaluated in the first three sessions to identify the child's functions. In the intervention period, 12 session (B), task-oriented intervention was applied; the child engaged in many of the activities in kindergarten, such as painting, writing, making, and cutting with scissors. Visuomotor coordination and fine motor coordination were equally measured during the baseline and intervention periods. Visuomotor coordination was measured via drawing of an oval according to the Korean Developmental Test of Visual Perception 3 (K-DTVP-3), and fine motor coordination was assessed using the finger-nose touching item of the Clinical Observation of Motor and Postural Skills (COMPS). Results : The mean of the baseline of the K-DTVP-3 oval drawing was 23, and the mean of the intervention period was 39.66. The mean of the baseline of the COMPS finger-nose touching was 0, and the mean of the intervention period was 5.08. Conclusion : Task-oriented intervention seems to have a positive effect on the visuomotor coordination and fine motor coordination abilities of children with developmental delay.

Objective : This study sought to investigate the effects of a sensory integration intervention focusing on vestibular and proprioceptive on the spatial relations and visual-motor coordination of children with developmental disorders. Methods : Three children with developmental disabilities aged 5 to 6 years were the subjects of this study, and the ABA' design, which is one of the single subject research designs. A total of 18 sessions were conducted over a six-week period-that is, three 30-minute sessions per week. During the three baseline sessions, the children's spatial relations and visual-motor coordination were evaluated prior to the intervention. During the 12 sessions conducted in the intervention period, a vestibular and proprioception sensory integration intervention was performed, while in the final three sessions, the children's spatial relations and visual-motor coordination were again evaluated (without any further intervention Children were measured and evaluated every session after intervention using a computer cognitive rehabilitation program (CoTras-C). Moreover, the Kaufman Assessment Battery for Children and the Korean-Development Test of Visual Perception-2 were used as evaluation tools to verify the effectiveness of the intervention. Results : There were significant differences in the spatial relations and visual-motor coordination scores of the children with developmental disorders before and after the vestibular and proprioceptive sensory integration intervention. More specifically, after the intervention, all three children showed statistically significant improvements. Conclusion : The applied vestibular and proprioceptive sensory integration therapy had a significant impact on the spatial relations and visual-motor coordination of the three children with developmental disorders.

The study area, which is located in the southeastern part of the Jirisan province of the Yeongnam massif, Korea, consists mainly of the Precambrian Sancheong anorthosite complex and the Jirisan metamorphic rock complex, the Mesozoic granitoids which intruded them. Several fracture sets with various geometric indicators, which determine their relative timing and shear sense, are well observed in the Sancheong anorthosite complex. The aim of this study is to determine the development sequence of extension fractures, the movement sense and development sequence of shear fractures in the Sancheong anorthosite complex on the basis of detailed analysis of their geometric indicators. This study suggests fracture system of the Sancheong anorthosite complex was formed at least through five different fracturing events, named as Dn to Post-Dn+3 phases. (1) Dn phase: extension fracturing event of NNW trend. The fracture set experienced the reactivations of dextral ${\rightarrow}$ sinistral shearing with the change of stress field afterward. (2) Dn+1 phase: extension fracturing event of (N)NE trend. The fracture set experienced the reactivations of sinistral ${\rightarrow}$ sinistral ${\rightarrow}$ dextral. (3) Dn+2 phase: extension fracturing event of NW trend. The fracture set experienced the activated of dextral shearing. (4) Dn+3 phase: extension fracturing event of N-S trend. (5) Post-Dn+3 phase: extension fracturing event of (E)NE trend. Dn deformation formed during the early Songnim orogeny. Dn+1 deformation formed during the late Songnim orogeny. Dn+2 deformation formed during the Daebo orogeny. Dn+3 deformation formed during the Bulguksa orogeny.

Lesch-Nyhan 증후근(LNS)은 hypoxanthine guanine phosphoribosyle transferase(HGPRT) 효소를 암호화 하는 X 염색체가 불완전해서 일어나는 유전적인 추제외로계(또는 기저핵)의 드문 병변이다. 출생시 LNS 유아는 정상적인 운동발달이 관찰되어진다. LNS에게서 현저하게 진단적인 특징으로 보여지는 운동심리적 행동인 self-mutilating 행위는 4살 이후에나 나타난다. LNS 아이들은 오히려 초기에 Rett's 증후근, 뇌성마비, 자폐, 다운증후근과 유사한 운동행위를 보인다. 그래서 LNS 아이들은 앞에 기술한 신경학적 장애로 오진을 받을 수가 있다. 오진으로 인해 초기에 적절한 치료를 받지 못한다면 LNS는 결과적으로 합병증(신장부전)과 self-mutilating 행위로 인하여 치명적일 수가 있다. 그러므로, 이 연구의 목적은 LNS 평가 동안 더 나은 진단을 하도록 하기 위하여 LNS와 관련된 기능부전에 대한 지식을 임상가들에게 제공하고자 함이었다. 연구 대상자는 10살인 2명의 쌍둥이 남아이었으며 실험은 뻗기 과제 수행(reaching task)시 움직임 특성을 보기 위하여 운동형상학적과 비디오 분석을 사용하였다. 기술통계로 분석 결과 움직임 시간과 단위가 증가됨을 보였고 사지의 분절적 움직임이 협응되지 않음을 보였다. ballistic과 jerky 움직임 양상은 dysmetric과 비긴장성 운동 행위에서 우세하였다. LNS은 추체로계 운동 장애 (과근긴장도나 저긴장도) 와 추체외로계의 운동 장애(dystonia와 choreoathetosis)의 혼합된 형태를 보였다. 결론으로 이 연구는 운동발달 장애를 가진 아이들을 치료하고자 할 때 임상가들한테 LNS 아이들의 움직임 장애의 다른 진단적 특징을 알아야 한다는 것을 제시하고자 한다.
