PURPOSE: The purpose of this study was to examine the problems and relevant variables for effective Organizational Socialization of new nurses, to produce a causal map, to build up a simulation model and to test its validity. METHOD: The basic data was collected from Sep. 2002 to July 2003. The Organizational Socialization process of new nurses was analyzed through a model simulation. The VENSIM 5.0b DSS program was used to develop the study model. RESULT: This Model shows interrelation of these result variables: organizational commitment, job satisfaction, job performance, intention of leaving the work setting, decision making ability, and general results of Organizational Socialization. The model's factors are characteristic of organization and individual values, task-related knowledge and skills, and emotion and communication that affects new nurses' socialization process. These elements go through processes of anticipatory socialization, encounter, change and acquisition. The Model was devised to induce effective Organizational Socialization results within 24 months of its implementation. The basic model is the most efficient and will also contribute to the development of knowledge in the body of nursing. CONCLUSION: This study will provide proper direction for new Nurse's Organizational Socialization. Therefore, developing an Organizational Socialization Process Model is meaningful in a sense that it could provide a framework that could create effective Organizational Socialization for new nurses.

PURPOSE: The purpose of this study was to determine the degree of undergraduate nursing student adaptation to college life and investigate the factors that influenced that adaptation. METHODS: First-year (undergraduate) students attending three nursing colleges were surveyed from November 24 through December 5, 2014; and data from 206 respondents were analyzed. For data analysis, multiple regression analysis was performed using the SPSS WIN 18.0 program. RESULTS: The findings showed that age (p=.002), emotional intelligence (p<.001), and self-efficacy (p<.001) were significant variables that influenced first-year undergraduate nursing student adaptation to college life. Undergraduate nursing student adaptation was explained by self-efficacy (beta=.327, p<.001), emotional intelligence (beta=.222, p=.001), satisfaction with education in their academic major (beta=-.217, p<.001), and academic achievement (beta=.136, p=.018); and, the explanatory power of these variables was 41.2%. CONCLUSION: To facilitate undergraduate nursing student adaptation to college life prior to clinical practice, developing and apply programs to improve self-efficacy, emotional intelligence, satisfaction with education in their major, and academic achievement is deemed necessary.

BACKGROUND: Tinea pedis is one of the most comrnon dermatoses in the general population. But its prevalence in the general populat,ion was not yet reported in Korea. OBJECTIVE: Prevalence of tinea pedis and associated tinea unguium were checked in the general population. METHODS: Six hundred fifty eight persons from 179 families of the college students were evaluated. Clinical examinatior. for tinea pedis and onychomycosis and collecting scales from the suspicious lesions of the family members were perforrned by educated college students. Then dermatologists exarnined those specimens mycologically by KOH ~tnount and fungal culture. RESULTS: The results were as follows 1. The prevalence of tinea pedis was 41.2% in the studied 658 persons. 2. Among all 271 patients with tinea pedis, 201 strains of dermatophytes were isolated. They were 143 strains of Trichophyton(T) rubrum, 49 strains of T. mentagrophytes and 9 mixed infections of T. rubrum and T. mentagrophytes. In the co existence of i,inea pedis and tinea unguiurn, isolated species were corresponding. 3. Among 179 families, 143 families (79.9%) had at least one patient with tinea pedis. The isolated species of derrnatophytes in a farnily were one organism, 71.4% and two or more organisms, 28.6% of 77 familiys with more than one patient. CONCLUSION: In our study, the prevalence rate of tinea pedis was 41.2%. That suggests that tinea pedis is a wide spr .ad disease in healthy adult in Korea.

Transesophageal echocardiography(TEE) is a new acoustic window to the cardiac structures and great vessels via retrocardiac esophagus. Because of the close relation between the esophagus and the heart, higher transducer frequencies can be applied, therefore leading to improved resolution and more accurate images than transthoracic echocardiography. We describe our experience with the first 353 awake patients. The procedure was well tolerated by the patients and associated with no major complications, within examination 10 to 20 minutes. Clinical diseases which appear to be suited for TEE includes 1) evaluation of native valve diseases, particulary mitral valve, pathologic valvular abnormalities and color Doppler regurgitant flows ; 2) assesment of prosthetic heart valves to better define malfunction and important pathologic associations ; 3) congenital heart disease, particularly atrial septal defect ; 4) endocarditis and detection of vegetations and complications ; 5) detection of thrombus and tumors, size, location, morphology, stalk ; and 6) aortic pathology including atherosclerosis, aneurysm and dissection. We conclude that transesophageal echocardiography is a new imaging technique that is rapidly evolving into a major tool for general cardiac imaging in a variety pathologic conditions and is a safe and useful tool in patients. Future advances in probe technology will continue to expand its applications.

PURPOSE: To evaluate the effect of all-trans-retinoic acid (ATRA) on the radiosensitivity of normal human oral keratinocyte (NHOK). MATERIALS AND METHODS: Relative cell survival fraction including SF2 (survival fraction at 2 Gy) was calculated on the basis of colony formation assay. Data were fitted to the linear-quadratic model to establish the survival curve and calculate alpha and beta values. Using flow cytometry at 1, 2, 3, 4, and 5 days after exposure to 2 and 10 Gy irradiation, cell cycle arrest and apoptosis were analysed. To understand the molecular mechanism of the radiosensitization of ATRA on NHOK, proteins related with apoptosis and cell cycle arrest were investigated by Western blot analysis. RESULTS: Treatment with ATRA resulted in a significant decrease of SF2 value for NHOK from 0.63 to 0.27, and increased alpha and beta value, indicating that ATRA increased radiosensitivity of NHOK. ATRA increased LDH significantly, but increasing irradiation dose decreased LDH, suggesting that the radiosensitizing effect of ATRA is not directly related with increasing cell necrosis by ATRA. ATRA did not induce appotosis but increased G2 arrest after 10 Gy irradiation, implying that the increased radiosensitivity of NHOK may be due to a decrease in mitosis casued by increasing G2 arrest. ATRA inhibited the reduction of p53 at 3 days after 10 Gy irradiation and increased p21 at 1 day after 10 Gy irradiation. Further study is required to determine the precise relationship between this effect and the radiosensitizing effect of ATRA. CONCLUSION: These results suggested that ATRA increase radiosensitivity by inhibiting mitosis caused by increasing G2 arrest.

PURPOSE: To assess the relationship between the direction of the indicating rod of the radiographic stent for ideal prosthetic design and the actual possible path of implant fixture placement when residual ridge resorption is considered. MATERIALS AND METHODS: The study materials consisted of 326 implant sites (male 214 cases and female 112 cases) from a total of 106 patients (male 65 patients and female 41 patients) who desired implant prostheses. Computed tomography of patients were taken and reformatted using ToothPix (R) software. Bony defects, bony sclerosis, the change of the direction of indicating rod, and root proximity of the adjacent teeth were examined on the CT-derived images. RESULTS: The rate of the irregular crestal cortex was relatively high on premolar and molar area of maxilla. Mandibular molar area showed relatively high rate of focal sclerosis on the area of implant fixture insertion. The position of the indicating rods were relatively acceptable on the molar areas of both jaws. However, the position of the indicating rods should be shifted to buccal side with lingual rotation of the apical end on maxillary anterior teeth and premolar area. CONCLUSION: Clinically determined rod direction and position of the indicating rod for implant placement was not always acceptable for insertion according to the reformatted CT images. The pre-operative treatment plan for implant should be determined carefully, considering the state of the alveolar bone using the reformatted CT images.

PURPOSE: This study was performed to analyze human maxillary and mandibular trabecular bone using the data acquired from micro-computed tomography (micro-CT), and to characterize the site-specific microstructures of trabeculae. MATERIALS AND METHODS: Sixty-nine cylindrical bone specimens were prepared from the mandible and maxilla. They were divided into 5 groups by region: the anterior maxilla, posterior maxilla, anterior mandible, posterior mandible, and mandibular condyle. After the specimens were scanned using a micro-CT system, three-dimensional microstructural parameters such as the percent bone volume, bone specific surface, trabecular thickness, trabecular separation, trabecular number, structure model index, and degrees of anisotropy were analyzed. RESULTS: Among the regions other than the condylar area, the anterior mandibular region showed the highest trabecular thickness and the lowest value for the bone specific surface. On the other hand, the posterior maxilla region showed the lowest trabecular thickness and the highest value for the bone specific surface. The degree of anisotropy was lowest at the anterior mandible. The condyle showed thinner trabeculae with a more anisotropic arrangement than the other mandibular regions. CONCLUSION: There were microstructural differences between the regions of the maxilla and mandible. These results suggested that different mechanisms of external force might exist at each site.

Hypereosinophilic syndrome is a rare disease characterized by marked peripheral eosinophilia and eosinophilic infiltration of many organs such as heart, lung, central nervous system, liver and spleen. This disease is defined by following criteria. First, sustained blood eosinophilia is greater than 1,500/mm3 longer than 6 months. Second, other apparent etiologies for eosinophilia must be absent, including parasitic infestation and allergic disease. Third, patients must have signs and symptoms of organ involvement. In Korea, some cases that eosinophil infiltrated lung, liver, gastrointestinal tract or skin were reported. In this report, we found a case showing myalgia, fatigue and eosinophilia in periodic health examination, and diagnosed hypereosinophilic syndrome.

BACKGROUND: Hemophilia A is the most common X-linked bleeding disorder with an incidence of 1/5,000 males. Inversions within the factor VIII gene cause almost half of all cases of severe hemophilia A. However, DNA-based diagnosis has previously been carried out only by linkage analysis in Korean hemophilia A families. In this study, we aimed to establish direct inversion detection using a single-tube polymerase chain reaction (PCR) assay. METHODS: We have modified a single-tube PCR assay that combines overlapping PCR with long-distance PCR; performing PCR directly from genomic DNA with four primers P, Q, A, and B that differentiate the wild type, inversion, and the carrier detected the inversion. RESULTS: Segments PQ (12 kb) and AB (10 kb) were produced in hemizygous wild-type males. Males with hemophilia A due to the inversion showed segments PB+AQ (11 kb) along with the 10 kb segment from the nonrecombined extragenic homologue. In 20 (18.7%) patients, an inversion was found. The three segments were readily identifiable and all PCR amplifications achieved uniform reproducible results. CONCLUSIONS: The PCR was successful for the direct detection of factor VIII gene inversions. The method is simple, inexpensive, and more standardized; therefore, it may be the natural starting point for ascertaining mutations in families with severe hemophilia A.
