Narratives are the old stories handed down for a long time, which are not personal creations but common ones for ages. They were formed from the public consciousness, passed orally and recorded in letters. There have been lots of studies on narratives about characters, whereas there have been poor in the studies on the great doctors. The author examined the narratives about great doctors in literature for successive generations, and made researches on world view and consciousness of reality reflected on the age directly or indirectly. The author inquired into the descriptions and constructions of the narratives separately, and classified the great doctors in literature into the miraculous doctors, eccentric doctors and righteous doctors. Therefore truly great doctor is the one who treats not only personal diseases but also social problems, and who tries to harmonize with human beings and nature.

This paper is a study of the system of liberal great books selection in universities of Korea. A questionnaire consisted of 14 questions was sent to 46 universities of which 42 universities responded. Results of the study can be summarized as follows: 1) Liberal great books selection system was operated 40% of universities, but 60% was not operated because of not preparation and without perception of necessity. 2) The name of liberal great books was varied in 11 kinds of 16 universities. It is desirable that the name is unified. 3) The founded year of liberal great books selection system was new comparatively with enhanced liberal education. 4) The greater part of liberal great books format were a leaf of catalog, but it is desirable that book form catalog with review for induction of reading interests. 5) It is desirable that renewal of liberal great books are irregularly in answer to a need. 6) It is a n.0, ppeared that selection of liberal great books were by professor, but it is desirable that selection is by many people of all parts without prejudices and subjectivity. 7) The title of liberal great books were 121 titles in average. It is desirable that the titles are about 100 titles for expected results. 8) In a duplicates of liberal great books, 5 copy is much more than other cases. It is desirable that the duplicates depend on students, use rates, budget etc. of universities. 9) Use rates of liberal great books are much more than other books, but it is necessary that public relations and stimulation of reading for most use. 10) In subject analysis, liberal great books consisted of humanities, social sciences and novel mainly. Specially, literature is 33% of the total. 11) Liberal great books consisted of occidental works and literature mainly. 12) It is a n.0, ppeared that analysis of a n.0, ppointment frequency was scattered exceedingly.

Background: Occipital neuralgia is characterized by pain, usually deep and aching, in the distribution the second and/or third cervical dorsal root. Two broad groups of patients include primary occipital neuralgia with no apparent etiology and secondary neuralgia with structural pathology. Patients with occipital neuralgia can develop autonomic changes and hyperesthesia. In patients who have not improved with conservative treatment, we have carried out various nerve blocks and evaluated the effectiveness. Methods: In a series of 20 occipital neuralgia patients with no apparent etiolgy, we have carried out great occipital nerve blocks with needle TEAS. In patients who have not improved more than 75% on VAS with great occipital block, we have carried out C2 ganglion blocks and in patients who have not improved more than 75% with C2 ganglion block, C3 root blocks, C2/C3 facet joint blocks have been carried out in due order. Results: In 3 patients out of 10 patients who have not improved with great occipital nerve block, C2 ganglion block led to pain relief. A good response of C3 root block was achived in 2 of 7 patients without response to C2 ganglion block and C2/C3 facet joint block led to improvement in 1 of 5 patients without response to C3 root block. Conclusions: Nerve blocks like great occipital nerve block, C2 ganglion block, C3 root block, or C2/C3 facet joint block were effective in the patients who have not improved with conservative treatment.

This report describes a variation of the tendinous slip of the flexor digitorum longus (FDL) for the great toe. In addition, compositions of the long flexor tendons for all five toes were examined. The tendons of the FDL in the foot were investigated in 66 specimens of embalmed Korean adult cadavers. The tendons of the flexor hallucis longus (FHL) and the FDL with the lumbrical muscles were cut at the calcaneus and the metatarsophalangeal joints and were removed en bloc specifically to observe the FDL and the FHL tendons of the great toe. The tendinous slip of the FDL for the great toe was found bilaterally in the foot of a 52-year-old male. Its prevalence was two of 66 specimens (3.0%). The tendinous slip of the FDL for the great toe passed forward the great toe, and it constituted the superficial portion of the long flexor tendon for the great toe. The tendon of the FHL passed forward to constitute the deep portion of the long flexor tendon for the great toe. Thus, both the tendinous slip of the FDL and the tendon of the FHL composed the long flexor tendon for the great toe. The tendinous slip of the FDL and the tendon of the FHL for the great toe were similar in thickness; thus, each tendinous slip of the FDL and the tendon of the FHL were approximately one-half of the long flexor tendon for the great toe in thickness. The present study demonstrated an anatomical variation of the interconnection between the FHL and the FDL tendons, which will be useful for various surgeries and biomechanical research.

The Geo-Reservoir Experimental Analogue Technology (GREAT) cell was designed to recreate the thermal-hydro-mechanical conditions of deep subsurface in the laboratory. This apparatus can generate a polyaxial stress field using lateral loading elements, which rotate around the longitudinal axis of a sample and is capable of performing a fluid flow test for samples containing fractures. In the present study, numerical simulations were carried out for triaxial compression tests using the GREAT cell and the mechanical behavior of samples under different conditions of lateral loading was investigated. We simulated an actual case, in which triaxial compression tests were conducted for a polymer sample without fractures, and compared the results between the numerical analysis and experiment. The surface strain (circumferential strain) of the sample was analyzed for equal and non-equal horizontal confining pressures. The results of the comparison showed a good consistency. Additionally, for synthetic cases with a fracture, we investigated the effect of the friction and type of fracture surface on the deformation behavior.

It is known through prior research that the crust of the Korean Peninsula moves southeast at an annual average of 3 cm/year. The 2011 Great East Japan Earthquake caused a great change in the crust of the Korean Peninsula. Since then, the frequency of earthquakes has increased on the Korean Peninsula. Therefore, by using NGII and IGS GNSS observation data of the recent 15 years, to analyze the trends of changes in the deformation of the Korean Peninsula before and after the outbreak of the Great East Japan Earthquake. Data processing utilized Bernese Software V5.2, a widely used scientific and technical software around the world. As a result, the global movement of the Korean peninsula differed by about 4mm and the direction of movement by about 10° compared to before the Great East Japan Earthquake. As for the internal distortion of the Korean Peninsula, the East-West expansion of the Korean peninsula's crust was observed during the Great East Japan Earthquake, but it is believed that it has not fully returned to the level before the Great East Japan Earthquake.

Sonograms of songs recorded in Kwangnung and Chejudo were analyzed to investigate the features and variances in the songs of Great tit, Parus major variety. Songs of Great tits were identified, most of which were repetitions of phrases compoed of high-frequency note and low-frequency note. Variances between the songs of the two areas in the minimum and maximum of low-frequency were significat. The CV range of the Great tit group in Chejudo was wider than that in Kwangnung. Interregional variance level was significant in the minimum (P<0.04) and maximum (P<0.0001) of low-frequency.

The most common abnormal relationship between the great arteries and ventricle is transposition of great arteries, among which complete D-transposition is a common and lethal malformation. Without appropriate treatment, the infant born with transposition of the great arteries rarely survives the first year of life. In contrast to the grim hopelessness of only a few years ago, modern aggressive palliative and corrective surgical interventions can provide such infants with considerable hope for adolescent and adult life. Up until this time, intraatrial baffle technique for re-direction of venous return, which was proposed by Mustard originally, has been successfully applied to infants and children in many foreign clinics with decreasing trend of the operative risk. In this report, we present one case of a 4 year-old girl having complete D-transposition of the great arteries with atrial septal defect, and reviewed the relevant literatures.

Early childhood education has a huge impact on the development of one's life. Therefore, it is necessary to implement effective education in childhood in order to develop abilities such as creativity, which is essential for future society. Thus, through narrative inquiry, the characteristics creativity factors, family backgrounds, and parenting styles of the three great Korean were identified, and the commonalities of the three were analyzed. Research shows that all three great people had intellectual curiosity and productive thinking skills. And most of them were born into economically rich families and had an environment where they could experience various things, and there were people who supported them. In addition, there were nurturing people around them who discovered talent and actively participated in education, and their parents formed a stable emotional attachment with their children.
