Posterior ankle impingement syndrome is one of the impingement syndromes characterized by posterior ankle pain that occurs during forced plantar flexion. This report presents a case of a 48-year-old PAIS patient with os trigonum syndrome accompanied by tenosynovitis of flexor hallucis longus. She was treated with complex Korean medicine to a good effect. The Numeric Rating Scale and the EuroQol 5-Dimension 5-Level were used to measure the impact of Korean medicine on the patient's pain and quality of life. Decreased NRS and increased EQ-5D-5L scores reflected improvement in her symptoms within 25 days. This study suggests complex Korean medicine treatment for PAIS may be beneficial for alleviating pain and improving quality of life.

Purpose: This study was to delineate the structural change of neural pathway after sequential motor learning using diffusion tensor imaging (DTI). Methods: The participants were 16 healthy subjects, which were divided by training (n=8) and control (n=8) group. The task for the training was the Serial Reaction Time Task (SRTT) which was designed by Superlab program. When the 'asterisk' shows up in the 4 partition spaces on the monitor, the subject presses the correct response button as soon as possible. The training group participated in the training program of motor learning with SRTT composed of 24 digits pattern in one hour per daily through 10 days during 2 weeks. Results: In the behavioral results the training group showed significant changes in the increase of response number and the reduction of response time than those of the control group. There was significant difference in the left inferior frontal area in the fractional anisotropy (FA) map of the training group in DTI analysis. Conclusion: Motor sequential learning as like SRTT may be needed to the learning of language and visuospatial processing and may be induced for the experience-dependent structural plasticity during short period.

Purpose: Sensory input is very important for proper performance of human. Two-point discrimination is the most widely used tactile sensory test. The purpose of this study was to find the changes in cortical activation patterns between tactile stimulation and two-point discrimination. Methods: Two healthy subjects participated in our study. fMRI scanning was done during 4 repeated blocks of tactile stimulation and two point discrimination of the right index finger tip. In one block, stimuli were repeated 10 times every three seconds. To determine the changes of cortical neurons during sensory input, intensity index was analyzed. Results: When tactile stimulation of the right index finger tip was completed, only contralateral primary somatosensory area was activated. In contrast, during two-point discrimination, both the primary somatosensory area and ipsilateral supplementary sensory area were activated. Conclusion: During two point discrimination, both primary somatosensory area and ipsilateral supplementary sensory area were activated. Therefore, two-point discrimination is required more complex and conscious activity than tactile stimulation.

단말에 대한 공정성을 고려한 이더넷 PON 시스템의 동적대역할당방법의 성능분석

박지원,윤종호,송재연,임세윤,김진희,Park Ji-won,Yoon Chong-ho,Song Jae-yeon,Lim Se-youn,Kim Jin-hee 한국통신학회 2004 韓國通信學會論文誌 Vol.29 No.11B

본 논문에서는 Ethernet Passive Optical Network(EPON)시스템에서 단말들에 대한 공정성을 부여하는 동적 대역할당 알고리듬을 제안하고 시뮬레이션을 통한 성능분석을 하였다. 기존 EPON에서는 Optical Network Unit(ONU)로부터 보고 받는 버퍼의 상태만을 고려하여Optical Line Termination (OLT)가 상향링크의 대역을 할당한다 이러한 ONU버퍼상태에 따른 대역할당방법은 ONU들에 대한 공정한 대역할당은 가능하지만 ONU에 연결된 단말들에 대한 공정한 대역할당을 보장하지 않는 문제가 있다. 예를 들어, 어떤 ONU에 연결된 어떤 단말로부터의 전송이 일시적으로 폭증할 경우, 급격하게 증가된 이 ONU의 버퍼상태가 OLT에 보고됨으로써, 이 ONU는 더 많은 상향 대역폭을 할당받게 된다. 이러한 대역할당의 결과, 상향전송이 많은 단말에 대해서는 많은 대역이 할당되지만, 상대적으로 전송량이 적은 단말들이 접속된 다른 ONU들에는 기존보다 감소된 대역이 할당됨으로써 이러한 ONU들에 접속되어 있는 단말들의 전송지연시간이증가되는 불공정성 문제가 발생한다. 이러한 문제점에 착안하여, 본 논문에서는 ONU가 보고하는 버퍼상태뿐만 아니라, ONU에 연결된 단말의 개수도 OLT에 보고함으로써, OLT가 단말들에 대한 공정한 대역할당을 할 수 있는 방식을 제안하였다. 제안된 방법의 성능분석을 위해 SIMULA 시뮬레이션 언어를 이용하여 EPON시스템을 모델링하였다. 각 단말과 ONU 관점에서의 수율과 지연시간, 시간에 따른 ONU의 버퍼 변화 등을 비교 분석한 시뮬레이션 결과로부터, 제안된 방법이 각 단말들에 대하여 대역을 공정하게 분배할 수 있음을 보였다. 마지막으로, EPON 시스템을 망사업자가 운용할 때, 최종단에 위치한 가입자 단말들에 대하여 공정하게 대역을 할당할 경우, 제안된 방법이 효율적으로 활용될 수 있을 것이다.고체 식품에서 보다 높게 나타났다. 이상의 결과에서 식습관이 치아우식발생과 밀접한 관계를 가지고 있으므로 초등학교 아동에 있어 치아우식을 유발할 수 있는 간식의 섭취를 줄이되 우식성 식품을 간식으로 섭취한 후에는 잇솔질을 반드시 실시하도록 하며 정규식사에서 치아를 보호하는 세정식품의 섭취에 대한 영양교육이 지속적이고 단계적으로 꾸준히 이루어져야 한다고 본다.lity regardless difference on companies, ages, departments, and authority of an employees. Second, Satisfaction on incentive for employees in Family Restaurants were not well received. Although these necessary demand, there is not yet incentive system operation to most of business. Especially, it is not even studied on Family Restaurants. This study should have been studied on more customers and spotted employees to be objective.

Then, a hierarchical language is to defeat its own purpose.중 행정부가 북한에 대해 실시한 포용정책이 어떠한 성과를 거두고 어떠한 문제점을 간과하고 있는가에 대해 논의하고, 대북 정책의 새로운 In this paper, we propose the dynamic bandwidth allocation algorithm for the IEEE802.3ah Ethernet Passive Optical Network(EPON) system to provide the fairness among terminals, and evaluate the delay-throughput performance by simulation. For the conventional EPON systems, an Optical Line Termination (OLT) schedules the upstream bandwidth for each Optical Network Unit (ONU), based on its buffer state. This scheme can provide a fair bandwidth allocation for each ONU. However, it has a critical problem that it does not guarantee the fair bandwidth among terminals which are connected to ONUs. For an example, we assume that the traffic from a greedy terminal increases at a time. Then, the buffer state of its ONU is instantly reported to the OLT, and finally the OW can get more bandwidth. As a result, the less bandwidth is allocated to the other ONUs, and thus the transfer delay of terminals connected to the ONUs gets inevitably increased. Noting that this unfairness problem exists in the conventional EPON systems, we propose a fair bandwidth allocation scheme by OLT with considering the buffer state of ONU as welt as the number of terminals connected it. For the performance evaluation, we develop the EPON simulation model with SIMULA simulation language. From the result of the throughput-delay performance and the dynamics of buffer state along time for each terminal and ONU, respectively, one can see that the proposed scheme can provide the fairness among not ONUs but terminals. Finally, it is worthwhile to note that the proposed scheme for the public EPON systems might be an attractive solution for providing the fairness among subscriber terminals.

This study presents a new estimation of optimal amount of B/L for infantry rifles and artillery weapons which are currently using in Korean Army. To do that, we analyzed current concept of B/L and methodologies used to compute B/L before, and re-calculate optimal amount of B/L to solve some problems founded. We also applied ARENA simulation model to propose estimated values of optimal B/L. The proposed optimal B/L will certainly help to improve efficiency for wartime readiness in the future. 본 연구에서는 현재 우리나라 육군이 사용하고 있는 보병화기와 포병화기(155M)의 기본 휴대량(B/L : Basic Load) 개념 정립 및 산정방법을 고찰하여 문제점을 도출하고 시뮬레이션 기법(ARENA Model)을 통해 최적의 B/L을 재산정하여 제시하였다. 본 논문을 통한 기대효과는 군수지원의 물동량 감소로 실질적인 전투 준비 태세 강화와 국방예산 절감이 예상되며, 효율적인 B/L운영 보장으로 전투 효율성을 증대시킴은 물론 궁극적으로 전장 승리를 보장하는데 기여할 것이다.

This study, a quasi-experimental study using a nonequivalent control group pretest-posttest design. conducted a survey on 30 patients test group and control group of IS patients sampling an adjacent population at random - who are operated on the breast cancer and are in the A University Hospital located in Suwon, to examine into the effects of foot reflex zone massage on their pain and sleep satisfaction through the nursing interventions. It gave them a foot reflex zone massage for the total 30 minutes-basic massage 10 minutes and reflex massage 20 minutes required to alleviate their pain day in day out covering a two-month period from the first of July to the first of September 2004. for the purpose of collecting data. It launched into a two-round foot reflex zone massage at 6 and 24 hours since mastectomy through a direct visit at the hospital room to measure pain intensity, physiological index(pulse and blood pressure) and sleep satisfaction of them. The results are as follows. First, it showed that there is all the difference between pain intensity of test group and that of control group. In result, the first hypothesis, pain of test group. which measure at 6(p=.000) and 24 hours(p=.001) since mastectomies, will be bigger than that of control group, was established. Second, it showed that there is all the difference between physiological index of test group and that of control group. In result. the second hypothesis, pulse(p= .025, p= .002), systolic blood pressure(p= .004, p=.012) and diastolic blood pressure(p=.004. p= .003) of test group, which investigate at 6 and 24 hours since mastectomies, will be bigger than that of control group, was established. Third, it showed that there is a significant difference between sleep satisfaction of test group and that of control group(p=.000). In result, the fourth hypothesis, sleep satisfaction of test group. which examine in the morning after mastectomies, will be bigger than that of control group, was established. In the result. a foot reflex zone massage is seen to be effective in the pain reduction and sleep promotion of patients who are operated on breast cancer, and in providing them with more qualitative care by improving confidence between them and nurses through a physical touch. Also, it can be applied to a clinical examination through an independent nursing intervention.

Objectives Although impulsivity has long been thought as an important factor influencing suicidal behaviors, it is unknown whether impulsivity increases the risk of dying from suicidal behaviors and what specific component among constructs of impulsivity contributes to the risk of dying among suicide attempters. Methods To elucidate the association between impulsivity and medical lethality of suicide attempt among suicide attempters, we consecutively recruited 46 suicide attempters who visited an emergency room of a general hospital located in a metropolitan area, Seoul, Republic of Korea, due to suicide attempts and consented to participate in this study. Then we assessed medical lethality with the Beck Lethality Scale (LS) and impulsivity with the Korean version of the Barratt Impulsiveness Scale-11-Revised (BIS). Demographic variables were obtained from medical records and structured social work reports for suicide attempters. Results Although total scores of the BIS did not correlate with LS scores, only the scores of self-control, that is one of the Barrett's six theoretical constructs of impulsivity in which the higher score indicates less self-control and more impulsivity, had a significant positive correlation with scores of LS (p = 0.003). The association remained significant after adjusting for variables known to affect suicide lethality such as job status, recent alcohol consumption, diagnosis of depressive disorders, and having a plan for suicide (${\beta}=0.429$, p = 0.009). Conclusions Not impulsivity in general, but poor self-control, in particular, predicts lethal suicidal behaviors among suicide attempters. The degree of self-control should be evaluated when assessing patients with elevated suicide risk, and proper measures should be installed to prevent possible future lethal suicide attempts.

Purpose: This study investigated the change in plantar fascia thickness in hemiplegic and non-hemiplegic feet in stroke patients using an ultrasonographic evaluation. Methods: Sixteen hemiplegic and non-hemiplegic feet from 16 hemiplegic patients (patient group) and 16 feet from 8 healthy subjects (control group) were evaluated by ultrasonography. The sagittal sonograms were obtained in the prone position, and the plantar fascia thickness was measured at its insertion into the calcaneus. Results: The mean plantar fascia thickness was measured to be $4.5\pm0.8$mm in hemiplegic feet of the patient group, $3.4\pm1.0$mm for the contralateral non-hemiplegic feet and $2.8\pm0.3$mm for the control group. There was a statistically significant difference in plantar fascia between the hemiplegic feet and contralateral non-hemiplegic feet as well as between the contralateral non-hemiplegic feet and control group (p<0.01 and p<0.05, respectively). The plantar fascia thickness according to the Brunnstrom stage and modified Ashworth scale was increased significantly in the hemiplegic feet (p<0.01). Conclusion: These results show that the plantar fascia is overloaded in the hemiplegic and non-hemiplegic feet of stroke patients. A therapeutic approach should be considered for these patients.
