PURPOSE: This study aimed to identify the relationship among knowledge, attitudes and prevention behaviors (PB) on tuberculosis (Tb) infection in nursing students. METHODS: 268 subjects were recruited from two universities located in C·D cities of Korea and data were collected utilizing self-reported questionnaires. RESULTS: The mean scores of knowledge, attitudes and PB on Tb infection were 64.83, 3.18 and 2.97. The knowledge differed according to gender (t=-3.16, p=.002), grades (F=32.19, p<.001), educational experience about Tb (EETb) (F=10.59, p<.001), learning information about Tb (t=3.08, p=.002) and getting Tb: self or others (t=2.78, p=.006). The attitudes differed according to grades (F=7.71, p<.001) and EETb (F=2.68, p=.047). The PB differed according to grades (F=7.02, p<.001) and EETb (F=4.55, p=.004). Significant correlations were found between knowledge and PB (r=.20, p=001), attitudes and PB (r=.33, p<.001). The most significant factor influencing PB was attitudes with R2 value of 13.9% (F=11.81, p<.001). CONCLUSION: These findings indicate that knowledge and attitude adjustment may be necessary to improve PB for Tb infection in nursing students. Moreover further study is necessary to find out the ways to reinforce the level of attitudes. The results of the study can be utilized in educational programs for preventing Tb infection in nursing students.

STATEMENT OF PROBLEM: To improve a direct implant fixation to the bone, various strategies have been developed focusing on the surface of materials. The surface quality of the implant depends on the chemical, physical, mechanical and topographical properties of the surface. The different properties will interact with each other and a change in thickness of the oxide layer may also result in a change in surface energy, the surface topography and surface, chemical composition. However, there is limited the comprehensive study with regard to changed surface and biologic behavior of osteoblast by anodization. PURPOSE OF STUDY: The aim of this study was to analyze the characteristics of an oxide layer formed and to evaluate the cellular biologic behaviors on titanium by anodic oxidation (anodization) by cellular proliferation, differentiation, ECM formation and gene expression. And the phospholipase activity was measured on the anodized surface as preliminary study to understand how surface properties of Ti implant are transduced into downstream cellular events. METHODS AND MATERIALS: The surface of a commercially pure titanium(Grade 2) was modified by anodic oxidation. The group 1 samples had a machined surface and other three experimental specimens were anodized under a constant voltage of 270 V(Group 2), 350 V(Group 3), and 450 V(Group 4). The specimen characteristics were inspected using the following five categories; the surface morphology, the surface roughness, the thickness of oxide layer, the crystallinity, and the chemical composition of the oxide layer. Cell numbers were taken as a marker for cell proliferation. While the expression of alkaline phosphatase and Runx2 (Cbfa1) was used as early differentiation marker for osteoblast. The type I collagen production was determined, which constitutes the main structural protein of the extracellular matrix. Phospholipase A2 and D activity were detected. Results. (1) The anodized titanium had a porous oxide layer, and there was increase in both the size and number of pores with increasing anodizing voltage. (2) With increasing voltage, the surface roughness and thickness of the oxide film increased significantly (p<0.01), the TiO2 phase changed from anatase to rutile. During the anodic oxidization, Ca and P ions were more incorporated into the oxide layer. (3) The in vitro cell responses of the specimen were also dependant on the oxidation conditions. With increasing voltage, the ALP activity, type I collagen production, and Cbfa 1 gene expression increased significantly (p<0.01), while the cell proliferation decreased. (4) In preliminary study on the relation of surface property and phospholipase, PLD activity was increased but PLA2 activity did not changed according to applied voltage. CONCLUSION: The anodized titanium shows improved surface characteristics than the machined titanium. The surface properties acquired by anodization appear to give rise more mature osteoblast characteristics and might result in increased bone growth, and contribute to the achievement of a tight fixation. The precise mechanism of suface property signaling is not known, may be related to phospholipase D.

Our purpose is to describe a successful twin pregnancy and delivery after intracytoplasmic sperm injection (ICSI) followed by calcium ionophore with spermatozoa from a globozoospermic man. On the second attempt of ICSI, all of eight metaphase II oocytes were fertilized with treatment with calcium ionophore. Day 3 transfer of six normally developing embryos resulted in an ongoing twin pregnancy, and two preterm healthy babies were born in the 33th week of gestation. To the best of our knowledge, this is the first report of pregnancy and delivery after ICSI followed by calcium ionophore with spermatozoa from a globozoospermic man in Korea.

BACKGROUND:Acute vestibular neuronitis is the disease of which the etiology and pathophysiology are largely unknown . But the viral infection and ischemia of the labyrinth and the vestibular nerve are considered as general etiology. This study was performed to support the viral infection rather than the ischemic theory. MATERIALS & METHODS:We studied seventy years old female patient who showed painful vesicles on left auricle and vertigo with spontaneous nystagmus to the right side. We performed physical examination, serologic test, ENG test, pure tone audiogram, brain magnetic resonance imaging and polymerase chain reaction. RESULTS:We found small vesicles and vascular injection in left EAC, herpes zoster IgG positive, spontaneous right beating in electronystagmograpy, 54% left canal paresis in Caloric test , decreasing left side Tc in velocity step rotatory test, decresed gain, deviation to left in symmetry and phase lead in sinusoidal harmonic acceleration test, normal range hearing in pure tone audiogram, microangiopathy on cortex in brain MRI and negative PCR. CONCLUSION:This case supports viral infection etiology rather than ischemia in vestibular neuritis. But more studies to find the etiology of vestibular neuronitis are required.

The anti-inflammatory activity of a corticosteroid may mask the contact allergic reaction it is causing. This may be an important reason why contact allergy to corticosteroids has often been missed. A simple persistent aggravation of a dermatitis in a patient treated with one or more topical corticosteroids is sufficient to raise a suspicion of corticosteroid hypersensitivity. A 23-year-old male visited our department for the evaluation of his aggravated pruritic oozing erythematous papules, scales and edema of the face. Previously, he was treated with Dermatop ointment and Plancollotion. A Patch test showed positive reactions to prednicarbate 10%, 1%, hydrocortisone-17-butyrate 10%, and triamcinolone 10%. We conclude prednicarbate in Dermatop ointment, hydrocortisone-17-butyrate in Plancol lotion to be the etiological agents.

BACKGROUND: Acne is a common chronic disease which most frequently affects the face. This visibility is a major cause for concern in affected individuals. OBJECTIVE: The purpose of this study was to investigate the quality of life of patients with acne. METHODS: We interviewed 130 acne patients, and determined the impact of acne on the quality of life with a questionnare. RESULTS: Among 130 cases of acne, the numbers of male and female patients were 52(40.0%) and 78(60.0%) respectively, and tbe mean age was 21 years. There was no difference between the sexes in the quality of life criteria used. The scores of social criteria of patients older than 20 years were significantly higher than thme of patients younger than 20 years. The severity of facial acne was correlated with the severity of chest acne but not with that of back acne. The severity of chest acne was correlated with that of back acne. The severity of facial acne was correlated with the scores of the physical, social and psychological criteria, and the severity of chest acne was correlated with that of physical and social criteria. However, the severity of back acne was not correlated with those of any of the criteria. The psychological well-being of the patients was moderately or highly affected by the acne more often than the other criteria. CONCLUSION: Acne has a substantial impact on the quality of life. The practical use of these indices are: (1) reveal areas of particulur concern in patients with acne; (2) to identify individuals who may require more intensive treaiment; and (3) to give a patient oriented inforrnation on the quality of life expected.
