건강검진에서 혈압, 혈당과 더불어 빠지지 않는 항목이 바로 간 수치다. 흔히 간 수치가 높다 낮다 등으로 표현하는데, 정확한 의미를 아는 사람은 많지 않다. 간 수차(간 효소 수치)는 간이 얼마나 튼튼한지를 나타내는 척도다. 이 같은 간 수치를 알아보는 간 기능 검사는 1차적으로는 소변을 받고 혈액을 뽑으면 된다. 따라서 검사 전 금식은 필수다. 만약 1차 검사에서 이상이 발견되면 2차 혈액 검사를 진행하거나 종양표지자, 복부초음파, CT, MRI, 복강경, 복부혈관조영 등 다양한 방법으로 심층적인 검시를 진행한다. 간은 2/3가 손상돼도 정상기능을 유지하는 반면, 기능을 상실하기 전까지 이렇다 할 증상이 없어 질환을 알아차리기가 쉽지 않다. 그래서 간을 '침묵의 장기'라는 고약한 별칭이 따라붙는 이유다. 간 기능 검사를 통해 수시로 점검하는 길만이 최선이다.

검출부를 목적부분에 접촉시켜 지시부에서 볼수있도록 한 간이형인 것이다. 대개는 서모커플을 검출소자로서 사용하고 있으나 서미스타를 사용한 것도 있다. 서모커플은 시정부다 적게 잡혀 광범위한 온도측정이 가능하나 원리적으로 상온부근의 오차가 크다. 서미스터는 사용온도 범위가 비교적 좁고 시정수도 서모커플에 비하여 크나 상온부근에서 정도는 높다.

This paper is about the results in Qualification Management activity performed between the Autonomous Test(AT) season(August. 2008) of Launch Complex and the 2nd flight test season(June. 10, 2010) of KSLV-I. All cryogenic fluids(LOX, $LN_2$) and compressed gases(Air, $GN_2$, GHe) were qualified by qualification management activity during AT(Autonmous Test), QT(Qualification Test) season for LP(Launch Pad) and LVAB(Launch Vehicle Assembly Building) and FT(Flight Test) season of KLSV-I. As the results, total 428 times of check analysis and 111 times of full analysis were performed.

The purpose of this study was to investigate the effects of cognitive programs on cognitive function improvement in patients with mild dementia. The subjects were 30 patients with mild dementia. The subjects were applied the cognitive rehabilitation program three times a week for 6 weeks and analyzed the pre-experiment and post-experiment values through the Korean simplified mental state examination (MMSE-K). The results were as follows: The mean of test was increased and statistically significant. Thus, cognitive rehabilitation programs for patients with mild dementia are effective interventions to improve cognitive function in patients with dementia.

Objectives：We developed a Korean version of the Brief Measure of Worry Severity(BMWS), and examined its reliability, validity, and factor structures. We also explored the associations of pathological worry with depression and anxiety. Methods：Three hundreds fifty-two subjects including community population and college students completed the BMWS, and 27 subjects repeated the scale three weeks later. Reliability was assessed by Cronbach's coefficient ${\alpha}$ and test-retest correlation. The external validity was examined by the correlation of the BMWS score with the scores of Beck Depression Inventory(BDI), Patient Health questionnaire-2(PHQ-2), State Anxiety Inven-tory(SAI), and Trait Anxiety Inventory(TAI). And principal component analysis was performed to evaluate the construct validity. The associations of pathological worry with depression and anxiety were explored using partial correlation analysis. Results：Cronbach's coefficient ${\alpha}$ for the BMWS was 0.904 and test-retest correlation was 0.56(P<0.01). The Spearman correlation coefficients of the BMWS score with the scores of BDI, PHQ-2, SAI, and TAI were 0.60(P<0.01), 0.42(P<0.01), 0.36(P<0.01), and 0.59(P<0.01), respectively. The BMWS showed unifactorial construct. When controlling for TAI score, the correlation coefficient between the BMWS score and the BDI score was 0.357(P<0.01), and when controlling for BDI score the correlation coefficient between the BMWS score and the TAI score was 0.446(P<0.01). Conclusion：The Korean version of the BMWS was found to be a reliable and valid questionnaire for measuring pathological worry. And we could identify the associations of the pathological worry with depression as well as anxiety.

간장에 공간점유성병변(암, 농양, 낭종성병변, 혈종 등)이 있을 때는 정적간이미징에서 모두 냉구로 나타난다. 따라서 진단적 특이성이 없다. 그러나 감마카메라를 적절히 잘 이용하면 간암과 간농양을 쉽게 그리고 단시간내에 진단 및 감별할 수 있다. 즉 간암이나 간농양이 의심되는 환자에게 핵제제를 이용한 간동맥기에 열구로 나타나서 정맥기에도 계속 더 강한 열구로 나타내게 되며 간섭취기에는 열구의 음영이 점점 약해져서 종말에는 선명한 냉구로 변해 버린다. 그러나 간농양은 간동맥기, 간정맥기 및 간섭취기 모두에게 계속 냉구로 나타나므로 쉽게 간암과 감별진단이 가능하다. 한편 이 검사는 정적간이미징을 위하여 핵제제를 경정맥투여시에 부담없이 시행하게 되므로 루틴화가 가능하며, 앞으로 간암의 조기진단에 크게 기여하리라 확신한다.

The purpose of this study was to investigate the effects of early cognitive training and tailored telephone coaching program for ischemic stroke. Among 28 participants, assigned into the experimental(n=15) and control group(n=13). Only the experimental group was received a 4-week cognitive training and 11 session of tailored telephone coaching. The effect ot the program was evaluated four times(baseline, 4weeks, 8weeks, 12months) using the tool on Depression, Mini Mental State Examination(MMSE), Neuropsychological battery, Activities of Daily Living(ADL). The repeated measures ANOVA showed that the experimental group showed improvement in MMSE, verbal memory and executive function compared to the control group. Especially, the improvement of executive function which is related to ADL was a remarkable result. This suggests that early intervention is very important for recovery cognitive function and independent daliy life after stroke, and periodic telephone coaching should be done together for mid-to long term effects.

Recently, with increasing the number of patients with head injury and cerebrovascular accident, there has been an increasing need for the useful assessment tools of brain dysfunction and it's localization. With the advances in the neuroscience since the mid-1970s, particularly in the areas of neuroanatomical tracing, neuroimaging, and improved behavioraltest design, it has been possible to develop a more precise understanding and localization of brain dysfunction. However, these equipments are not readily available in the private clinics and too expensive to use as a screening tool to all suspected patients with brain dysfunction. Although several screening tests such as Mini-Mental States Examination(MMSE) or Brief Cognitive Rating Scale(BCRS) are simple in use and useful for the brief assessment of brain dysfunction, these are also limited in using for localization of brain dysfunction because of their simplicity. With increasing need of the assessment tool which is able to localize the dysfunction more precisely in the clinical practice, we planned to develop the new assessment tool, the Bedside Neurocognitive Function Localization Test(BNLT) which is suitable for this purpose. The BNLT was designed to be utilized for localizing brain dysfunction effectively and readily in the clinical practice. We introduced the whole process of designing the BNLT in this manuscript.

임상적으로 흔한 간질환인 지방간은 대부분의 경우에 초음파검사에 의해 진단이 된다. 초음파검사에 의한 지방간과 대장암의 전구병변이 될 수 있는 대장용종과의 관련성을 검진환자대상으로 일반요인과 대사증후군 요인 등 특정요인과 비교분석 하였다. 대장용종은 나이 50세 이상, 남자일수록, 공복시 glucose와 Triglyceride 수치가 높을 때, 지방간이 있을 때 발생빈도가 높았다. 상관관계분석에서는 지방간이 용종과의 관계도가 가장 높았고 위계적 회귀분석에서도 용종발생에 가장 영향력 있는 요인은 지방간이었다. 지방간인 경우 대장내시경검사를 고려해야 할 것이다.

Interaction between pain and sleep has long been proved through many researches, and various studies are being conducted to identify its mechanism. However, these studies have targeted on patients with systemic disease, such as rheumatic disease and fibromyalgia. There are few researches on patients with orofacial pain including temporomandibular disorder(TMD). In this study, we studied interaction between pain aspect and sleep quality in 229 patients with TMD, who visited the TMJ and Orofacial pain clinic. Pittsburgh Sleep Quality Index(PSQI), Epworth sleepiness scale(ESS) questionnaire were surveyed and sleep-screening device was operated. PSQI showed that sleep quality in TMD patients with pain was poorer than that in TMD patients without pain. The ratio of poor sleeper was higher in TMD patients with pain. Especially, TMD patients with chronic pain showed obviously poorer sleep quality than TMD patients with acute pain. The result of ESS showed that patients with painful TMD showed more daytime sleepiness than painless TMD patients. The ratio of TMD patients with chronic pain who had daytime sleepiness was higher than TMD patients with acute pain, and the amount of daytime sleepiness was higher in the group of chronic pain. In TMD patients with chronic pain, only the poor sleeper(PSQI>5) presented mean ESS>10(diagnostic criteria of daytime sleepiness). There was no correlation between pain intensity and sleep quality or daytime sleepiness. The result of ApnealinkTM for screening of sleep related breathing disorder showed that only 1 patient presented AHI>5 among 19 participants. TMD patients with chronic pain presented poor sleep quality and excessive daytime sleepiness similar to other chronic pain patients. Evaluation of sleep state by questionnaire might be useful for diagnosis and management of TMD, because sleep disturbance decreases pain threshold and pain disturbs sleep. In addition, sleep-screening device would be useful for screening sleep related breathing disorder in dental clinic.
