Objective : The purpose of this study was conducted to find scapular movement instability related with shoulder complex and provide strengthening the scapular muscles with proprioceptive neuromuscular facilitation(PNF). Methods : This is a literature study with books and articles, seminar note and book for PNF international course. Results : The scapular serve as the platform for humeral motions. The scapulothoracic articulation is stabilized and controlled, in part, by the scapular muscles. Therefore, if scapular muscle function is altered, then dysfunctional scapulothoracic kinematics may result. Strengthening exercise for scapular muscles are a common part of rehabilitation programs designed for patients with scapular instability. Conclusion : Treatment of the scapular instability is provided. It is that treatment with combination of isotonic, stabilize reversal on different patient's positions.

Purpose: The aim of the present study was to investigate the effects of proprioceptive neuromuscular facilitation (PNF) and taping interventions on balance ability, joint position sense, and ankle joint strength. Methods: Thirty subjects who had experienced an ankle sprain within the previous 3 months participated in this study. The subjects were randomly assigned to a PNF group (n=15) or a taping group (n=15). Before and after the interventions, ankle dorsi-flexion and plantar-flexion strength, joint position error, and total center of pressure movements in one leg while in a standing position were measured. Results: Regardless of the group allocation, ankle dorsi-flexion and plantar-flexion strength significantly improved after the interventions (p<0.05). Compared to preintervention measurements, joint position errors were significantly reduced postintervention (p<0.05). The PNF intervention significantly decreased the total lateral movement of the center of pressure in the one leg standing condition (p<0.05). Conclusion: Both PNF and taping interventions improved joint position sense and ankle joint strength. In common with the findings of a previous study, the PNF intervention improved balance ability. Further study is required to investigate the effects of various PNF and taping interventions on ankle performance in subjects with chronic ankle sprains.

Purpose: The purpose of this study was to investigate the influence of opposite lower extremity lateral muscle activation by proprioceptive neuromuscular facilitation (PNF) exercise targeting the lower extremities. Methods: Nineteen patients with chronic hemiplegia volunteered to participate in this study. PNF flexion, abduction, and internal rotation patterns; initial, end range, and extension patterns; abduction and internal rotation patterns; and initial and end range patterns were applied to the dominant lower extremity. Activation of lateral muscles (multifidus, gluteus medius, tensor fascia lata, and peroneous longus) of the paralyzed leg was then measured by electromyography (EMG). Results: There were significant differences in lateral muscle activation, depending on the PNF pattern applied, with the differences more significant in flexion, abduction, internal rotation, and end range patterns. Conclusion: PNF flexion, abduction, and internal rotation patterns can improve lateral muscle activation of one leg in the standing position in the gait cycle.

The global trading system is vulnerable to terrorist exploitation while the international trade is an essential element for the economic development. Customs has a unique role in the international trade to provide increased security while ensuring facilitation of the legitimate flow of goods and the role of Customs has become more and more indispensable these days. In response to this trend, the World Customs Organization(WCO), the organization of more than 170 Customs administrations all over the world, adopted an international framework("SAFE Framework") in 2005, which includes the Authorized Economic Operator(AEO) concept, whereby a party involved in the international movement of goods would be approved by Customs as complying with the supply chain security standards, and given benefits, such as simplified Customs procedure and less Customs intervention. In this stream, the Japanese government has developed and promoted AEO Program in close cooperation with the business sector, aiming at ensuring security while facilitating legitimate trade. For that purpose, Japan Customs, as a main entity in the field of international trade, has developed comprehensive AEO program with combination of programs for importers, exporters, warehouse operators, Customs brokers and logistics operators, such as forwarders and carriers, which are consistent with the "SAFE Framework" developed by the WCO. The purpose of this paper aims to analyse the introduction plans of AEO program for the trade security and trade facilitation with Japanese AEO system.

Purpose : The purpose of this study was conducted to find out observation at gait analysis of the stroke patient with proprioceptive neuromuscular facilitation(PNF) concept. Methods : This is a literature study with books, seminar note and international PNF course book. Results : Stroke patient gait was poor initial contact by weakness of tibialis anterior or weakness of contralateral plantar flexor, poor loading response by loss of deep sensation, poor mid stance by loss of deep sensation, weakness of tibialis anterior and weakness of plantar flexors eccentric control, poor terminal stance, pre-swing, initial swing by loss of deep sensation and stiffness fo deep toe flexors. Conclusion : Stroke patient gait determine on loss of mobility, pain, fear, trunk muscle weakness, loss of coordination, loss of deep sensation, neglect and apraxia. Therefore observational gait analysis of the stroke patient focus on gait cycle and take out hypotheses from the gait cycle. These hypotheses have to define accept or not by parameters. Treatment plan made with the hypotheses.

This study examined how the resources from work, family and community lowered family-to-work conflict (FWC) and enhanced family-to-work facilitation (FWF) of employed women with a child younger than 18 years old in order to provide empirical support for the Korean government's effort to create a family-friendly community as a way to help employed mothers balance work and family life. Information from 608 employed mothers living in 45 different communities were extracted from the 4th-wave of the Korean Longitudinal Survey of Women and Families in 2012, while community resources indicators were selected from the 2012 database of the Korean Statistical Information Service. Findings from the HLM analysis were as follows. First, there were significant variation in FWC and FWF among employed mothers depending on the communities they resided in. Second, work satisfaction, representative of work resource, relieved FWC and enhanced FWF, but spousal support, which represents family resource, affected neither FWC nor FWF. Third, community resources, as represented by family-friendly environment and frequent volunteering by community residents, lowered FWC but failed to enhance FWF. Lastly, family-friendly community resources served to mitigate the negative relationship between work satisfaction and FWC. This study is meaningful in that it provided empirical evidence for the contribution of community resources to work-family balance of employed mothers.

Objectives: The purpose of this article is to summarize the effect of stretch stimulus on muscle contraction facilitation. Methods : Some studies of the stretch reflex. ${\gamma}-motor$ system, and the effect of stretch stimulus on muscle activation were reviewed. Results : To facilitate muscle contraction, before the movement is started, the prime mover is in stretched position. The patient must be instructed to occur voluntary muscle contraction after quick stretching. It elicits the functional stretch reflex to produce a more powerful and functional contraction. The intensity of muscle contraction depends on two ways. One is firing rate of ${\alpha}-motor$ neuron by sensory information from the periphery induced in stretched position and stretch reflex. The other is excitation level of the cortical motor area and the corresponding motor neurons. Conclusions: To activate central nervous system and to increase firing rate of ${\alpha}-motor$ neuron. the therapist should apply quick stretch for the patient with stretched position and the patient should make voluntary muscle contraction.

Objective : The purpose of this study was conducted to find correct head and neck patterns, manual contact. verbal commands with proprioceptive neuromuscular facilitation(PNF). Method : This is a literature study with books, seminar note and book for PNF international course. Result : Keep the information of the biomechanics and neural science in head and neck patterns and emphasize that manual contact, verbal commands and visual stimulus. Manual contacting for movement guide and stability of the $C_0/C_1$ verbal command and visual stimulus for correcting of the $C_0/C_1$ movements. Conclusion : In reminder for PNF learning, begin with head and neck and upper trunk patterns. In that time, Knott and Voss(1968) had not enough information about biomechanic movement components and neural science movement components. But Knott and Voss(1968) emphasized that head and neck patterns relate with trunk, upper extremities and lower extremities directly. Alar ligaments are relaxed with the head in neutral and taut in flexion. Axial rotation of the head and neck tightens both alar ligaments. The right upper and left lower portions of the alar ligament limit left lateral flexion of the head and neck. Therefore, head and neck patterns has to be modify. When head moving, eye and vestibular stimulus will be change. During head and neck patterns, must be consider about stimulus of eye system and vestibular system also.
