Abdominal actinomycosis is a chronic, progressive, suppurative disease with a fa-vorable response tointravenous treatment with penicillin. In many instances, howev-er, its clinical and radiological findings mayoverlap with those of other inflammatory and neoplastic conditions, and the familiarity with the variousradiological features can thus avoid diagnostic delay s. The purpose of this paper is to describe and discuss theCT findings of abdominal actinomycosis.

A relatively rare and puzzling tumor of the testicular tunic is reported. The tumor, so called a fibrous pseudotumor of testicular tunics, in presented because of the clinical dilemma this rare entity causes urologists and pathologists. This report demonstrates the necessity for familiarity with testicular pseudotumors in order to avoid an unnecessary orchiectomy.

BACKGROUND AND OBJECTIVES: Acceptable noise level (ANL) is a measure of the maximum background noise level (BNL) that a person is willing to tolerate while following a target story. Although researchers have used various sources of target sound in ANL measures, a limited type of background noise has been used. Extending the previous study of Gordon-Hickey & Moore (2007), the current study determined the effect of music genre and tempo on ANLs as possible factors affecting ANLs. We also investigated the relationships between individual ANLs and the familiarity of music samples and between music ANLs and subjective preference. SUBJECTS AND METHODS: Forty-one participants were seperated into two groups according to their ANLs, 29 low-ANL listeners and 12 high-ANL listeners. Using Korean ANL material, the individual ANLs were measured based on the listeners' most comfortable listening level and BNL. The ANLs were measured in six conditions, with different music tempo (fast, slow) and genre (K-pop, pop, classical) in a counterbalanced order. RESULTS: Overall, ANLs did not differ by the tempo of background music, but music genre significantly affected individual ANLs. We observed relatively higher ANLs with K-pop music and relatively lower ANLs with classical music. This tendency was similar in both low-ANL and high-ANL groups. However, the subjective ratings of music familiarity and preference affected ANLs differently for low-ANL and high-ANL groups. In contrast to the low-ANL listeners, the ANLs of the high-ANL listeners were significantly affected by music familiarity and preference. CONCLUSIONS: The genre of background music affected ANLs obtained using background music. The degree of music familiarity and preference appears to be associated with individual susceptibility to background music only for listeners who are greatly annoyed by background noise (high-ANL listeners).

The characteristic radiographic and CT findings of Iobar atelectasis are well known. However, Iobar atelectasis is a dynamic process, and atypical presentations may occur due to a number of different causes. Familiarity with the various typical and atypical radiographic findings of Iobar atelectasis is important for correct diagnosis. The aim of this manuscript is to illustrate the spectrum of radiographic findings of Iobar atelectasis and to correlate the radiographic findings with the CT findings. The review will illustrate examples of typical and atypical Iobar atelectasis, including combined Iobar atelectasis, peripheral Iobar atelectasis, migrating Iobar atelectasis, rounded atelectasis involving the entire lobe and Iobar atelectasis mimicking paravertebral and mediastinal masses.

OBJECTIVE: Based on the TGAM PCB module, a system of emotion control using audio-visual feedback is designed. METHODS: TGAM collects EEG information through the electrode in contact with the forehead skin. The system analyzes the user's emotion through the STM32F103ZET6 of the main control chip, and finally controls the control end of the system to regulate the user's emotion. RESULTS: It can be seen from the test results that the system can precisely recognize the user's emotions, and at the same time effectively adjust the user's emotions from both audio-visual aspects. CONCLUSIONS The system has high recognition accuracy and good adjustment effect.

Calcific tendinitis of hand and foot is rare and frequently misdiagnosed because of its rare incidence and its similar clinical presentation to other conditions such as infection. Awareness of the typical location as well as familiarity with the imaging findings is essential for making a correct diagnosis of this rare condition. We report four cases of calcific tendinitis of hand and foot, occurring in the flexor hallucis brevis, abductor digiti minimi, and abductor pollicis brevis.

PURPOSE: The purpose of this study was to measure the level of uncertainty, credible authority, severity of illness and event familiarity in members of families where there is a patient with a mental illness and to examine the relationships among these variables. METHODS: Research data were collected from November 23 to December 7, 2010. Participants in the study were 96 family members who visited patients in a closed ward or out-patient department of one hospital in Goyang City. Self-report questionnaires were analyzed using the SPSS 18.0 Program. RESULTS: Mean scores were 79.8+/-11.23 for level of uncertainty in family members, 15.5+/-2.17 for credible authority, 13.3+/-2.02 for severity of illness, and 14.5+/-2.43 for event familiarity. Uncertainty in family members was significantly related to credible authority (r=-.52, p<.001), event familiarity (r=-.41, p<.001) and severity of illness (r=.22, p<.031). CONCLUSION: The results of the study indicate that credible authority, severity of the illness and event familiarity are major factors perceived uncertainty in members of families of these patients. This outcome suggests the need for a new trials in nursing interventions considering the effects of these variables.

To investigate the nature of artifacts caused by air and chemical shift by fat, a test tube phantom study was performed in 2.0T and 0.5T superconducting magnetic resonance imaging systems in various imaging sequences. Spatial mismapping and signal change made image distortion in spin echo images of the air-column and severe signal voids in gradient echo images. Chemical shift artifacts appeared in the planes of frequency-encoding axis as crescent-shaped signal voids and summated bright signals, Both artifacts were more prominent in high field strength, Images at 0.5T showed more severe artifacts in the T2-weighted images than those in the other sequences. As the acquisition matrix increased, truncation artifacts decreased and susceptibility artifacts in gradient echo images diminished. Familiarity with causes, appearances and mechanisms of various artifacts will help radiologists for interpretation of MRI.

BACKGROUND: It is thought that computer familiarity has increased significantly since 2004 as well as the use of computers. This study aimed to evaluate the effects of computer familiarity and types of keyboard and computer on the performance of the Korean computerized neurobehavioral test (KCNT), and to identify which parameters of KCNT were affected by aforementioned factors. METHODS: A total of 85 subjects were classified into three groups of computer familiarity by Korean typing speed. Their age, gender and the level of education were also collected. The parameters of KCNT included simple reaction time, choice reaction time, addition, symbol digit, and finger tapping speed. The test was conducted using three types of computers: a laptop computer, a laptop computer with a simplified keyboard, and a desktop computer with a simplified keyboard. RESULTS: Parameters including the simple reaction time, choice reaction time, addition, and symbol digit, and the finger tapping speed of non-dominant hand showed no significant differences in the results among the three groups by computer familiarity after age and educational years were controlled as covariates. The mean reaction time of the simple reaction time and the choice reaction time with a simplified keyboard was significantly shorter compared to that with a typical keyboard. With regard to type of computer, the mean reaction time of the simple reaction time and the choice reaction time was significantly reduced when performed with the desktop computer with a simplified keyboard. CONCLUSIONS: Unlike previous study results, the choice reaction time, the addition, and the finger tapping speed of dominant hand were the only parameters affected by the computer familiarity. Both the type of keyboard and the type of computer significantly influenced the simple reaction time and the choice reaction time. Therefore, it is recommended to use a desktop computer with a simplified keyboard for such parameters.
