  • Despite the consumption of bee brood in several parts of the world, particularly in the tropical areas, the practice has received comparatively little attention. We have reviewed all the available information on the nutrient composition and functional properties of different developmental stages of honey bee workers belonging to different species and subspecies. Noticing the competent nutrient composition of, in particular, honey bee brood, pupae, and prepupae, we suggest that they could be a potential source of human nutrition as well as animal feed. Moreover, drone brood is an ideal candidate for use as a food or as food ingredient. However, to analyze the functional properties of different honey bee species remains a task for further analysis.

  • An increasing number of adult congenital heart disease (ACHD) patients continue to require life-long diagnostic imaging surveillance using cardiac CT and MRI. These patients typically exhibit a large spectrum of unique anatomical and functional changes resulting from either single- or multi-stage palliation and surgical correction. Radiologists involved in the diagnostic task of monitoring treatment effects and detecting potential complications should be familiar with common cardiac CT and MRI findings observed in patients with repaired complex ACHD. This review article highlights the contemporary role of CT and MRI in three commonly encountered repaired ACHD: repaired tetralogy of Fallot, transposition of the great arteries after arterial switch operation, and functional single ventricle after Fontan operation.

  • Microarray data includes tens of thousands of gene expressions simultaneously, so it can be effectively used in identifying the phenotypes of diseases. However, the retrieval of functional information from a large corpus of gene expression data is still a time-consuming task. In this paper, we propose an efficient method for identifying functional categories of differentially expressed genes from a micro-array experiment by using Gene Ontology (GO). Our method is as follows: (1) The expression data set is first filtered to include only genes with mean expression values that differ by at least 3-fold between the two groups. (2) The genes are then ranked based on the t-statistics. The 100 most highly ranked genes are selected as informative genes. (3) The t-value of each informative gene is imposed as a score on the associated GO terms. High-scoring GO terms are then listed with their associated genes and represent the functional category information of the micro-array experiment. A system called HMDA (Hallym Micro-array Data analysis) is implemented on publicly available micro-array data sets and validated. Our results were also compared with the original analysis.

  • Objectives It is well known that problem drinking is associated with alterations of brain structures and functions. Brain functions related to alcohol consumption can be determined by the resting state functional connectivity in various resting state networks (RSNs). This study aims to ascertain the alcohol effect on the structures forming predetermined RSNs by assessing their cortical thickness. Methods Twenty-six abstinent male patients with alcohol dependence and the same number of age-matched healthy control were recruited from an inpatient mental hospital and community. All participants underwent a 3T MRI scan. Averaged cortical thickness of areas constituting 7 RSNs were determined by using FreeSurfer with Yeo atlas derived from cortical parcellation estimated by intrinsic functional connectivity. Results There were significant group differences of mean cortical thicknesses (Cohen's d, corrected p) in ventral attention (1.01, < 0.01), dorsal attention (0.93, 0.01), somatomotor (0.90, 0.01), and visual (0.88, 0.02) networks. We could not find significant group differences in the default mode network. There were also significant group differences of gray matter volumes corrected by head size across the all networks. However, there were no group differences of surface area in each network. Conclusions There are differences in degree and pattern of structural recovery after abstinence across areas forming RSNs. Considering the previous observation that group differences of functional connectivity were significant only in networks related to task-positive networks such as dorsal attention and cognitive control networks, we can explain recovery pattern of cognition and emotion related to the default mode network and the mechanisms for craving and relapse associated with task-positive networks.

  • This study was implemented to verify the feasibility of motor function recovery and the appropriate period for therapy. The research began with spinal laminectomy of 40 white rats of Sprague-Dawley breed and induced them spinal crush injury. Following results were obtained by using the modified Tarlov test (MTT), Basso, Beattle, Bresnahan locomotor rating scale (EBB scale) and modified inclined plate test (MIPT). First, the measurement using the MTT confirm that the most severe aggravation and degeneration of functions are observed two days after induced injury, and no sign of neuromotor function recovery. Second, better scores were achieved by open-ground movement group on BBB locomotor rating scale test, and weight-bearing on inclined plate group show better performance on MIPT. Third, both BBB and MIPT scale manifested the peak of motor function recovery during 16th day after the injury and turn into gradual recovery gradient during 16th to 24th. Fourth, the control group showed functional recovery, however, the level of recovery was less significant when compared with group open-ground movement group and weight-bearing on inclined plate group. Hence, it was clearly manifested that the lumbar region of the spinal cord had shown the best performance when its functions were measured after the execution of specific physical training; therefore it indicated the possibility of learning specific task even in damaged lumbar regions. Thus it is expected to come out with better and more effective functional recovery if concentrated physical therapy was applied starting 4 days after the injury till 16 days, which is the period of the most active recovery.

  • Business process engineering (BPE) is a top-down management approach for increasing efficiency and productivity through radical and fundamental changes to the business processes of the organization. BPE requires firms to initially develop a model of the existing business processes of the firm to distinguish functional tasks from processes used for coordinating inputs, activities and outputs. The model is used for understanding the business processes in the organization and to simulate the effect of changes to the processes. The model can also be used to justify business processes, which involves assessing whether the business process provides value to the customer in its current configuration. Justification requires a careful examination of the key business processes used by the firm to identify systemic shortcomings in the process and to create a new business process to produce greater efficiency. BPE also considers automating as many business processes as possible to increase operational efficiency and the integration of business process tasks. The construction industry has been slow to adopt BPE because of its project approach in which a major firm contracts with various functional service providers and regards each project as unique. The industry focuses on functional task efficiency rather than business process efficiency. There is no formal methodology or criteria for determining whether a business process is effective for a construction firm in its current configuration. The use of performance measures such as costs, task duration times or other metrics can be useful in evaluating the effectiveness of an existing business process and for modeling the possible outcome of a fundamental and radical change to the process.

  • 초등학교 수학에서 함수적 사고는 매우 중요하지만, 함수적 사고를 지도하는 데 중요한 역할을 하는 교사에 대한 연구는 부족한 편이다. 이에 본 연구에서는 함수적 사고를 지도하기 위한 수학 과제 및 수업 전략에 대한 지식을 살펴보기 위하여 검사 도구를 개발한 후 초등학교 교사 119명을 대상으로 조사하였다. 분석 결과, 초등학교 교사들은 대부분 곱셈 관계와 덧셈 관계의 과제를 적절하게 개발할 수 있었고, 비연속적인 대응표의 활용과 같은 수업 전략에 대하여 함수적 사고 지도의 측면에서 설명할 수 있었다. 반면 일부 교사들은 함수적 사고에 대한 중요한 아이디어를 충분히 이해하지 못했다. 연구 결과를 토대로, 함수적 사고를 지도하기 위한 초등학교 교사의 지식에 관하여 시사점을 논의하였다.

  • In an attempt to measure effects of the Programmed Resistance Exercise on the daily performance of patients with rheumatoid arthritis, a quasi-experiment ; non-synchronised control group pre-post-test, was carried out for 8 weeks : from June 3 to November 29, 1996. 25 for the experimental group and 26 for the control group were conveniently sampled among registered out-patients on rheumatoid arthritis clinic of Anam Hospital, Korea University Medical Center. The programmed experimental resistance exercises were carried out by the experimental group five times a week for eight weeks. Before and after experiments, level of functional task performance, functional disability, joint mobility, ESR, CRP, self-efficacy and family support were measured and statistically analysed. The results of the analysis of the effects on the Programmed Resistance Exercise are as follows : 1. A statistically significant post-test effects on functional task performance were revealed : 1) the experimental group climbed up and down the 10 steps of the stairs significantly faster than the control group(P=0.0001). 2) the experimental group walked 100 m significantly faster than the control group (P=0.0000). 3) After the experiment, the experimental group could sit down and get up from chairs with no armrest as low as 30cm, 40cm, 50cm on their on, with no assistance as opposed to the control group who could not sit down and get up from such low chairs (P=0.0084). 4) the experimental group lifted 0-15 kg object up to their own heights with no specific strain than the control group (P=0.0000). 2. A significant reduction in the functional disabilities was revealed in the experimental group(P=0.0017). 3. A notable incresement of the joint mobility was revealed in the experimental group. 4. A decrease in the ESR in both the experimental and the control groups was noticed, however, the difference was not statistically significant (P=0.9546). 5. The CRP of both the experimental and control groups decreased with no significant difference (P=0.6022). 6. The self-efficacy increased significantly in the experimental group(P=0.0042), however, no significant effect of self-efficacy on the actual practice of the program was noticed. 7. The family support revealed to be significantly higher in the experimental group (P=0.0013), however, the effect of the family support on actual practice of the program revealed not significant. Judging from the results of these experiments, the resistance exercise program not only improves the functional capacity of rheumatoid arthritis, but also diminishes their functional disabilities and has a great influence on increasing their joint mobility, self-efficacy, and family support. Concluding, in promoting the daily performance of rheumatoid arthritis, the resistance exercise program would be an appropriate nursing intervention.

  • Purpose: The purpose of this study was to evaluate the effect of task-oriented exercise and abdominal muscle contraction using functional electrical stimulation (FES) on abdominal muscle thickness and balance of stroke patients. Methods: Ten stroke patients who met the selection criteria were assigned randomly into two groups of five. One group received FES therapy before task-oriented training (experimental group), while the other group received a FES placebo before task-oriented training (control group). The Mann-Whitney U test was used to compare the groups, and the Wilcoxon Signed-ranks test was used to compare differences between the groups before and after intervention. The Mann-Whitney U test was used to compare the rate changes of each item before and after intervention, between the two groups. Results: In the rectus abdominalis and external oblique muscle thickness tests that used ultrasound, there was a statistically significant difference in the experimental group (p<.05),but no significant difference in the control group (p>.05). There was also a significant difference between the groups (p<.05). In the Balance test that used the Berg Balance Scale (BBS) and timed up and go test (TUG), there was a statistically significant difference in the experimental and control groups (p<.05), but there was no significant difference between the groups (p>.05). Conclusions: FES therapy before task-oriented training increases the thickness of abdominal muscles and improves balance abilities.
