뇌파검사는 뇌전증을 가장 정확하고 빠르게 진단한다. 또한 뇌의 기능과 발작을 장소의 구애를 받지 않으면서 실시간으로 평가할 수 있는 중요한 검사이다. 뇌전증 분야에서는 뇌파검사지식과 임상경험이 많은 임상병리사가 PA를 하는 것이 적합하다. 전극 부착 방법은 국제 표준 10-20법을 기반으로 한다. 뇌파 판독은 주로 LB몽타주로 판독한다. 하지만 한 가지 몽타주만 이용하여 판독하는 것은 오류를 범할 수 있기 때문에, 상황에 맞게 2개 이상의 몽타주를 병용해서 판독한다. 뇌파에서 전위는 등고선의 형태로 보인다. 뇌파 진단에서 가장 중요한 원리는 과잉 판독이 아닌 과소 판독이다. 뇌파를 반복해서 기록할수록 더욱 민감하게 판독할 수 있다. 좋은 뇌파 판독을 위해서는 양질의 좋은 뇌파가 기록되어야 한다. 그러기 위해선 신경과 의사와 뇌파 기사의 관계가 매우 중요하다. 앞으로는 많은 판독 경험과 임상적 실무지식을 갖춘 임상병리사의 활동영역이 좀 더 확대되길 기대한다.

Recently, the student internship has been introduced in medical schools as a way of preparing students with training experience and medical knowledge by performing clinical practice. This study discusses student internship management and ways to operate the internship effectively. Catholic University of Daegu School of Medicine has set up a 6-week internship program for fourth-year undergraduate students. In most of the sections, students have shown their satisfaction, particularly when they have received appropriate feedback and attention from their professors. The students found that performing the evaluation and treatment of patients and individual chart recording were informative and helpful. However, they felt a lack of basic knowledge and clinical skills and had difficulty in understanding their roles and in time management. The success of an internship depends on the passion and interest that professors show for their students along with active support from the other faculty and thoughtful consideration of patients and all their friends and family members. In addition, with growing awareness of the need for the student internship, it is necessary that the school executive provide financial and administrative support to the faculty and staff, clarify roles and the work needed to perform the tasks, ensure substantiality of the individual program with professors or departments, provide enough preliminary courses, and monitor outcomes and reflection.

This study was aimed to implement the electroglottography (EGG) system for analyzing fundamental frequency of the phonation. EGG was recorded from the conductance between ring electrodes attached to the neck skin area near thyroid cartilage with high frequency carrier electric signals during vocalization, and voice signal was recorded with microphone simultaneously. EGG and voice signals were transmitted to the audio port in PC and recorded with stereo sound recording program. From the digitized data, several parameters such as pitch, jitter, shimmer, CQ and SQ were analyzed from the vowel sounds. For the voice training, sound fundamental frequency was displayed during the vocalization and singing a song using pitches analyzed from the EGG. The system implemented in this study could be used for vocal exercise.

Purpose: This study was done to analyze nursing assessment and nursing care for pain in the electronic nursing records for the elderly patients with abdominal pain visiting the Emergency Medical Center. Methods: This study is a descriptive study based on nursing records from January to December 2015. A total of 1155 records for elderly patients with abdominal pain were gathered. Results: The mean age of elderly patients whose records were analyzed was 75.2 years. Analysis of nursing records regarding pain management showed that semi-urgent severity (93.7%), direct emergency room visits (58%), and 6.01 hours of emergency room stay (6.01 hours)were the most frequently documented characteristics of the elderly patients with pain complaints. Recording time of nursing assessment for abdominal patients was 1.01 hour; the average pain intensity was 3.97. The mostly used nursing intervention for abdominal pain was medication (65.1%). There was no record of non-pharmacological pain nursing interventions. Conclusion: The results of this study showed that improving knowledge and nursing practice for pain management is much of necessity. In particular, development of the non-pharmacological nursing interventions for pain is needed. Further research is also imperative to develop and evaluate record systems for pain management that can be used in the emergency room.

The experience of pediatric deep brain stimulation (DBS) of the globus pallidus internus (GPi) in the treatment of early-onset DYT1 generalized dystonia is still limited. Here, we report the surgical experience of bilateral GPi-DBS under general anesthesia by using microelectrode recording in a 7-year-old girl with early-onset DYT1 generalized dystonia. Excellent improvement of her dystonia without neurological complications was achieved. This case report demonstrates that GPi-DBS is an effective and safe method for the treatment of medically refractory early-onset DYT1 generalized dystonia in children.

Presuming that firing neurons have motions inside the MRI magnet due to the interaction between the neuronal magnetic field and the main magnetic field, we applied motion encoding gradients to dissected snail ganglia to observe faster responding MRI signal than the BOLD signal. To activate the snail ganglia in synchronization with the MRI pulse sequence, we used electrical stimulation with the frequency of 30 Hz and the pulse width of 2s. To observe the fast responding signal, we used the volume selected MRI sequence. The magnetic resonance signal intensity, measured with 8 ms long motion encoding gradient with a 20mT/m gradient strength, decreased about $3.46{\pm}1.48%$ when the ganglia were activated by the electrical stimulation.

SNOMED CT browser is a browsing tool for searching clinical terms in SNOMED CT which is a standard terminology set used worldwide. The search result view of previous browsers merely list up candidate terminologies. The problem is that most of users become confused about how to select an appropriate term from the list. This leads serious waste of medical recoding cost. This paper discusses characteristics of SNOMED CT dataset and proposes a novel design of enhanced result view by restructuring the results using relationships of SNOMED CT concepts. Using the proposed scheme, medical doctors or officers can select appropriate terms more efficiently and can reduce overall recording time.

Flap monitoring is important for flap salvage. Although there are many methods to observe the flap, practical methods mostly used are subjective methods. Recording flap surface temperature is one of the objective methods of flap monitoring. We used an infra-red thermometer to simplify monitoring of the flap temperature. 60 groin flaps of SD rats are used in the experiment. Artificial arterial or venous insufficiency was made and the surface temperature was checked and compared with body temperature. In the results, the temperature of the arterial clamped flaps was lower than that of body and the mean difference was $0.3^{\circ}C$ after 20 minutes of clamping. In the vein-clamped flaps, the mean decrease was $0.4^{\circ}C$ after 30 minutes of clamping. The all difference of the temperature between the flaps and body was statistically significant. Our results suggest that flap monitoring by infra-red thermometer is simple, useful and helpful to evaluate the flap status.

We have developed the digital polysomnograph system to enhance the manual sleep study. This system is composed of host PC and target board. The host computer is IBM-PC Pentium 133 MHz and the target board is PC31 (processor type: TMS320C31). These two Processors communicate with each other by dualport RAM. Target board acquire 16 channel sleep signals from the Polysomnographic system (GRASS model 78, USA) and digitize them. We used high resolution monitor$(1600{\times}1280)$ to simulate the paper-recording quality of polysomnographic signal. We also implemented the GUI based polysomnographic staging program on the windows environment. Clinicians can score the sleep stage, and edit and mark the event efficiently. Finally it can support making patient database.

The purpose of this study is to explore the acceptance intent of groups of experts and users for converged medical equipment using NeuroTech. This healthcare equipment is applied with technology that simultaneously enhances body function and cognitive function. Interviews were conducted with groups of experts and users to investigate the acceptance of equipment. The interviews include health problems for the elderly, the need to develop medical equipment, and the effectiveness. After recording the collected historical data, we performed the data analysis in accordance with the procedures of the phenomenological analysis method. The total number of people interviewed was 27, 16 experts and 11 users. As a result of the interview, we derived seven topic groups for each of the 12 topic groups and user groups. The implications were derived based on the results.
