This review will summarize EEG studies of learning and memory based on frequency bands including theta waves (4-7 Hz), gamma waves (> 30 Hz) and alpha waves (7-12 Hz). Authors searched and reviewed EEG papers especially focusing on learning and memory from PubMed. Theta waves are associated with acquisition of new information from stimuli. Gamma waves are connected with comparing and binding old information in preexisting memory and new information from stimuli. Alpha waves are linked with attention. Eventually it mediates the learning and memory process. Although EEG studies of learning and memory still have controversial issues, the future EEG studies will facilitate clinical benefits by virtue of more developed and encouraging prospects.

Ganglioneuroma is a rare benign tumor which originates in the neural crest, and is found along the path of the sympathetic chain, from the base of the skull to the pelvic cavity. Due to the slow growth of this type of tumor, it may be detected incidentally, or detected by virtue of the attendant pressure effects on adjacent structures. We report one case of ganglioneuroma arising in the pelvic cavity.

Highly reproducible and consistent ischemic stroke models are critical for obtaining more confident data. To date, the infarct variation of several ischemic rat models is considerable. Therefore, many factors related to outcome variation and infarct growth must be controlled. Among various infarct models of rodents, intraluminal filament model is common by virtue of its consistency of the success rate and the outcomes. Recently more long-term evaluation of functional and imaging outcomes is considered in terms of clinical practice. Concise and subsequent outcome assessment could result in the improvement of translational stroke research. We recommend that the researchers should remember the guidelines addressed by the Stroke Therapy Academic Industry Roundtable (STAIR) and the Good Laboratory Practice (GLP).

Human understanding is one of the three virtues that are expected of physicians in Harrison's principles of internal medicine, and it was emphasized that a Shakespearean breadth is needed to be the true physician. Recently, there has been an increase in the need for human understanding, such as a continuous increase in GB stones, an association between the patient's life events and pancreaticobiliary diseases, an increase in autoimmune disease, and a high recurrence rate after treatment. Therefore, we attempted a holistic and fundamental approach for figuring out the pathogenesis of pancreaticobiliary diseases including human habit loop and adaptive response and suggests the model for the development of pancreaticobiliary disease considering human understanding.

OBJECTIVES: The purpose of this study was to assess organizational citizenship behaviors (OCBs) and organizational personality types (OPT) perceived by public health center workers and to analyze differences in perceptions according to organizational characteristics. METHODS: The subjects of this study were workers at 12 of the 22 public health centers in Chonnam Province, South Korea. To measure organizational characteristics, we employed the OPT Index and OCBs Index. Data were collected for one month, from 15 September to 14 October 2009. Data for 422 workers were used in the final analysis. Descriptive statistics and t tests were performed as appropriate, utilizing SPSS/WIN 14. RESULTS: Among 16 types of OPT, ESTJ, ISTJ and ESTP were the most prevalent for the 12 public health centers. The average weight of OCBs was 4.77, and courtesy and civic virtue held the first and the second ranks among OCBs, respectively. Statistically significant differences between types of OPT were detected, in that T type was gender (p=.007) while J type was age (p=.010), education (p=.043) and career (p=.000). Statistically significant differences between OCBs were found in age, education and career. CONCLUSION: Public health centers should have programs to innovate OPT and to improve OCB. The development of such programs should consider characteristics of public health center workers such as age, gender, education and career.

Melanotrichoblastoma is a variant of pigmented trichoblastoma that shows highly pigmented epithelial lobules and differentiation toward the hair bulb. Histologically, the tumor presents features of trichoblastoma, and the histological findings are remarkable by virtue of the heavy melanin deposits found within and around the tumor cell nests. For the immunohistochemistry, abundant dendritic melanocytes (with the expressions of S100 protein, tyrosinase and most importantly, gp100/HMB45) are found within the tumor masses. We report here on a rare case of melanotrichoblastoma in a 57 year-old female patient.

Trichogerminoma is a rare cutaneous adnexal tumor that dysplays differentiation toward the hair germ epithelium. This tumor was first described by Sau et al. in 1992 and it is characterized by densely packed round nests or cell balls resembling hair bulbs. Herein, we report on a deeply pigmented and sharply circumscribed nodular tumor that was excised on the abdomen of a 48-year-old woman. Histologically the tumor involved both dermis and subcutis without any epidermal connection. The main nodule was subdivided into the smaller lobules by fibrous stroma. The lobules were composed of masses of basaloid cells that displayed peripheral palisading. Within the lobules, the basaloid cells formed numerous cell balls. The tumor presented the characteristic features of trichogerminoma. Interestingly, our case was the pigmented type, which was remarkable by virtue of the heavy melanin deposits found within and around the tumor nests. To the best of our knowledge, this is the first case of pigmented trichogerminoma that has been reported worldwide.

PURPOSE: The purpose was to identify marriage expectation and related factors among college students. METHODS: Data was collected by questionnaires from 329 college students in K university in Daegu. The data was analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. RESULT: Marriage expectation among college students was significantly different according to gender, age and opportunities for employment. Marriage expectation among college students correlated with sex role attitudes. Significant predictors influencing marriage expectation were age, opportunities for employment, mother's job, and sex role attitudes, A combination of these predictors accounted for 10.3% of the variance in marriage expectation. CONCLUSION: These findings show that marriage expectation is influenced by age, opportunities for employment, mother's job, and sex role attitudes. Therefore when nursing interventions are developed to improve marriage expectation, these factors need to be considered.

PURPOSE: This descriptive study was done to identify effects of perceived organizational support (POS) on job involvement and organizational citizenship behavior (OCB) in hospital nurses. METHODS: Data were collected from Oct. 1 to Nov. 15, 2011. Participants in this study were 324 nurses working in 6 general hospitals in S, K, and C cities. Data were analyzed using descriptive statistics, t-test, ANOVA, Scheffe test, Pearson correlation coefficients, and multiple regression. RESULTS: POS was positively correlated with job involvement, and OCB (altruism, conscientiousness, courtesy, sportsmanship and civic virtue). Factors influencing job involvement were POS and marital status, which accounted for 15.7% of the variance, marital status influenced altruism, which accounted for 4% of the variance, POS influenced conscientiousness, which accounted for 10% of the variance, religion and marital status influenced courtesy, which accounted for 6.5% of the variance, age influenced sportsmanship, which accounted for 7.9% of the variance, and POS and clinical career influenced civic virtue, which accounted for 23.1% of the variance. Job involvement mediated on the relation between perceived organizational support and organizational citizenship behavior. CONCLUSION: The results of the study indicate that hospital administrators should explore ways of improve POS for better job involvement, conscientiousness, and civic virtue.

The purpose of this study was to identify calls, roles and attitudes of the Christian medical staff in a modern medical system for holistic healing through belief in God's healing methods and God's view about medical treatment. The meaning of healing in the Bible is derived from Rapha in the Old Testament, it's meaning is 'heal wound', 'restore to original condition', 'repair', 'console' and 'be heal'. In the New Testament, the meaning of healing is 'to serve' and 'be in one's service' derived from Therapuein and 'preserve', 'rescue', 'save a life from death' derived from Sozo. Therefore the meaning of the healing in the Bible is restoring original completeness to the same as God's characteristics. The meaning of disease is physical, psychological, social and spiritual imbalance or disharmonious. Disease is usually depravity from moral life to immoral life and abnormal life process with accompanying specific symptoms. Medical staff were called to God's work, recognized God's will for them, and absolutely leaned on God's power to intervene and work above spatial-temporal transcendently. They use spiritual power with medical treatment skills, help sick people to possibly have dynamic and individual relation with God and help to maintain their well-being and complete healing. Attitudes of medical staff were compassion and love, virtue of modesty, strong and daring, patience with belief, healing with God's word, using spiritual insight, play, using medical knowledge and techniques, continuing spiritual training, laying on of hands and repentance.
