The purpose of the research study is to confirm in effectiveness of somatosensory stimulation and to propose ideal training strategy for functional recovery of stroke patients. Through the previous literatures, our study investigated to the advantages and disadvantages in electrical somatosensory stimulation for stroke patients. Also, our study suggested to applicable strategies and confirmed to growth direction about new somatosensory stimulation therapy for functional recovery in stroke patients. Result of research study, although many study demonstrated to the effectiveness about somatosensory stimulation therapy for stroke patients, many therapists have experienced many difficulties in somatosensory stimulation application for stroke patients in rehabilitation environments. Thus, few have the therapeutic tools for somatosensory or specific sensory input. However, apparently the previous literatures showed that effectiveness of somatosensory stimulation on functional recovery of patients with brain damage. In conclusion, we can be confirmed that an ideal somatosensory stimulation program is very effective in promoting recovery and the integrity of the somatosensory pathway of stroke patients. Furthermore, we anticipate that using the customized mechanical interface provides to positive effects in rehabilitation of patients with brain damage.

The purpose of this study is to investigate the recovery of sensation and the restoration of upper limb function according to transcranial direct current stimulation over the primary somatosensory cortex in patients with chronic stroke with sensory deficit. 20 patients with chronic stroke divided into 10 experimental groups and 10 control groups. Patients received transcranial direct current stimulations over the primary somatosensory cortex on the side of the stroke lesion, and The control group applied sham tDCS to the same location. Intervention was conducted 5 times a week, 20 minutes per session for a total of 2 weeks. Assessment was performed using the Erasmus MC modifications to the Nottingham Sensory Assessment(EmNSA), Semmes-Weinstein monofilament examination(SWME) for somatosensory, and Fugle-Meyer Assessment(FMA), Motor Activity Log(MAL), and accelerometer for upper extremity function. Assessment was conducted before and after the intervention. As a result of the study, the experimental group showed a significant improvement in the overall tactile sense, proprioception, cortical sense, and perception sensitivity than the control group, and showed a statistically significant difference in the usage amount of the upper limb. Based on the results of this study, it is thought that the possibility of effective clinical application of transcranial direct current stimulation for recovery of somatosensory and upper extremity function is thought to be increased.

When one sensor cannot provide information by sensory deficit or loss, the sensory information can be provided by substituting other sensors for the defected sensor. This sensory substation might be influence on the deteriorated motion perception that consists of multi-sensory information such as visual, vestibular and somatosensory information. In this study, to investigate whether the additional sensation by sensory substitution could be integrated into the motion perception, we examined the effect of substituted postural sway sensation on the directional perception of body movement. Deteriorated motion perception by the reduced plantar sensation was enhanced under sensory substitution condition that provided the body sway information as the plantar vibratory stimulus. These results imply that the additional sensation might be integrated into and improve the motion perception.

체성-교감 반사 유발시 동맥혈압의 조절에 관여한다고 생각되는 상부 복외측 연수 내의 심혈관계 세포를 대상으로 흥분발사의 반응특성을 측정, 분석하였다. 심장 박동주기와 시간적으로 동기되는 흥분발사를 보이는 심혈관계 세포를 찾은 후 체성-교감 반사의 승압반응과 감압반응을 유발시키며 각각에 대해 동일한 세포의 흥분발사의 변화를 측정한 결과 5가지 유형의 반응특성을 얻을 수 있었다. 이들 간에 구성되어 있는 회로망 연결을 설명하고자 2 가지 종류의 특성 세포와 적절한 자극 전달 경로 및 세포간 회로망 연결을 도입하여 본 연구의 실험결과를 모두 설명할 수 있는 가장 간단한 죄소 세포회로망 모델을 구성하였다. 최소 모델의 고찰 결과 고유한 감압경로의 존재가능성이 도출되었다.

We measured the body composition, including bone mineral density (BMD) and food resource availability using dual energy X-ray absorptiometry and the carbon and nitrogen stable isotope ratios of body condition of 4 anuran species(Hyla japonica, Glandirana rugosa, Pelophylax nigromaculatus, Lithobates catesbeianus) in South Korea. Additionally, the carbon and nitrogen stable isotope ratios were employed to determine the food resource availability of anurans. We figured out the relationship between the body composition, including BMDs and food resource availability. The body composition and BMDs did not differ between male and female while there was difference among the species. Food resource availability and BMDs were the highest in L. catesbeianus, the lowest in H. japonica. BMDs tended to increase with higher food resource availability. Body composition and BMDs, which represent the body condition of an individual, can be used as an ecological indicator to assess the stability of the habitat of anurans.

The present study aims to verify the usefulness of microcurrent stimulation as an effective intervention for managing body shape. Thirty female college students with a percentage body fat of 30% or more participated as subjects and belonged to the one of three groups; control group, combined exercise group, microcurrent stimulation group. Based on the results of analyzing the measurement data from pre- and post-intervention for four weeks for each group, the following conclusions were obtained. There was no statistically significant difference in all measured variables in the control group. However, waist circumference and TC were significantly reduced in the combined exercise group, and also weight, percentage body fat, waist circumference, and apolipoprotein were significantly reduced in microcurrent stimulation group. Considering the above conclusions, it can be suggested that microcurrent stimulation could be an effective intervention to improve body composition and blood lipid profile to have a healthy body.

This exploratory qualitative study investigates the effects of experiencing domestic violence on male adolescent offenders' masculinities. Empirical and theoretical literature suggests that negative male role models in violent families result in male adolescents' experiencing conflict in constructing gender identities, especially masculinities. Moreover. criminologists argue that masculinities are often connected with crimes as a way to prove masculine competence. This study compares male adolescent offenders who have experienced domestic violence with those who have not experienced domestic violence and explores how domestic violence experiences influence the construction of gender identities among male adolescent offenders. The study used a secondary qualitative data analysis method. The data consisted of ethnographic in-depth interview transcripts, observational field notes, and formal facility records collected at a juvenile correctional facility in Minnesota. The process of data analysis was a "constant comparative method" that sought to understand differences and similarities in the expressed gender narratives and identity patterns between the two groups of offenders. This process also examined differences within each group. The qualitative data analysis revealed that domestic violence experiences in childhood may be related to the construction of gender identities during adolescence. The findings of this study showed that male adolescent offenders who had experienced domestic violence tended to attach themselves to oppressed mothers more readily than those who had not experienced domestic violence. Next, their attachment to mothers related to the construction of more relational gender identities although most participants, regardless of domestic violence experiences, had much in common regarding gender expression. Finally, despite these relational gender identities, male adolescent offenders who had experienced domestic violence tended to depend upon violence and crimes to show masculine competence, as did male adolescent offenders who had not experienced domestic violence. The study findings suggest a need for research to understand the construction of gender identities in the context of particular experiences and the importance of building theories that advance a comprehensive understanding of the construction of masculinities and youth crime. This study also discusses the development of social work programs that protect young men from adherence to exaggerated masculinity, which is often associated with crimes.
