The objective of this study is to review of the incidence of temporal bone fractures and complications resulting from temporal bone fractures and to analyze the correlation between clinical and radiological findings. A series of 49 patients who were diagnosed temporal bone fracture with rhinorrhea, bloody otorrhea, admitted to Soonchunhyang University Chon-an Hospital from January 1997 to September 1999, were studied retrospectively. Clinical analyses were focused on age, sex, type of accident, external wound site, CSF leakage, hearing loss and facial nerve palsy. The high resolution CT scan consisted of a series of 3-mm thick sections through the temporal bone using the GE CT scanner (General Electric Inc.). In radiologic analyses, fracture types of temporal bone were divided into longtudinal fracture(LF), transverse fracture(TF) and mixed fracture(MF) respectively. The CT scans were examined for mastoid antral haziness(MH), middle ear cavity haziness(MeH), ossicular chain disruption(OD), otic capsule fracture(OF), pneumocephalus(Pn). The type of facial canal fracture was classified as fracture of internal auditory canal portion(FIAC), fracture of perigeniculate portion(FPG), fracture of tympanic portion(FT), fracture of mastoid portion(FM). The correlation between clinical and radiological findings was analysed. A total of 49 fractured temporal bones resulted in 9 CSF fistula, 23 hearing loss( 13 conductive type, 7 sensorineural type), 17 facial nerve injuries ranging from mild paresis to complete paralysis. The mose common etiology of the injury was from a motor vehicle accident(28%). The type of fracture observed on high resolution CT scanning was a LF in 39(78%) patients, a TF in 7(14%) patients and a MF in 3(6%) patients. The majority of fractures terminate in the floor of the middle cranial fossa in LF and passed lateral to the otic capsule in TF. Average time of onset of delayed facial palsy was 3.5 days. No patient developed prolonged otorrhea or meningitis during hospitalization and there was no requirement of surgical management. Hearing loss was the most common complication of temporal bone fracture(48%). Conductive hearing loss was associated with middle ear cavity haziness and ossiclular chain disruption. in temporal bone CT. A total of 29 cases facial canal fracture in temporal bone CT resulted in 14 perigeniculate portion(FPG), 12 tympanic portion(FT), 3 mastoid portion(FM). There was no correlation between radiological facial canal fracture and clinical facial nerve palsy. Four of 17 patients with facial nerve injury required facial nerve exploration under general anesthesia. We thought that prognosis and therapeutic planning in patients with temporal bone fractures were based on the clinical and radiological findings.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

This study was conducted to provide field-based harvesting study information which can be used to select an optimal cable system for certain work conditions on steep grounds (>20° ground slope) in Korea. Toaccomplish this study objectives, we evaluated three cable yarding systems (RME-300T tower-yarder, Chuncheontower-yarder, FARMI tractor winch) working in typical work conditions for their yarding productivity and operational efficiency. Those yarders are commonly used for removing logs or trees on steep grounds in Korea. Under the same work conditions (average DBH of tree to be cut, 20 cm; yarding distance, 60 m; lateral yardingdistance, 10 m; and machine utilization rate, 70%), the average productivities were 33.04 m3/day, 38.47 m3/day, and 14.17 m3/day for RME-300T, Chuncheon tower-yarder, and FARMI, respectively. Our standardized cost comparison study also showed that the yarding cost was highest at 37,835 won/m3 with FARMI, followed byRME-300T at 25,105 won/m3 for the same work conditions. We found the lowest yarding cost with the Chuncheon tower-yarder at 20,520 won/m3 which was resulted primarily from high yarding productivity at theyarding distance (60 m). Our analysis suggested that a small machine such as FARMI could be a low-costyarding machine option for a cable yarding job with a short yarding distance (40 m or less). The Chuncheontower-yarder is well suited for a mid-range yarding distance job in Korea, ranged between 40 to 140 m. Ifyarding distance were longer than 140 m, the RME-300T tower yarder appears to be most cost-effective.

This study was to comprehend the effect by investigating the particulate size and ingredient, examining the each process size distribution and analyzing all kinds of the ions in incinerator. Incinerating the wood in the absence of control devices, the peaks appeared in coarse particle and it had trimodal distribution. Also in the presence of control devices, the best efficiency appeared in fine particel. Cl?? and SO₄², were mostly distributed in fine particle area and in coarse particle area respectively. In the case of synthetic resin incineration, the size distribution had the peak at both 0.865㎛ and 4.2㎛. In the presence of control devices, peak appeared at 5.95㎛ and the collection efficiencies of Cl??, SO₄², Ca², Na??, K?? were high. Incinerating the leather without control devices, the size distribution had the peak at both 2.58㎛ and 5.95㎛. The leather incineraton had the same collection efficiency as sythetic resin incineration. The coarse particle collection efficiency was high. It is adquate to use the above control devices, together with high efficiency collector like bagfilter. To select the adequate control devices, it is required to investigate the size distribution before establishing control devices.

중세초 교회와 교황제 성립에 관한 연구 : From the End of the Roman Empire to the Death of Theoderic

趙源弘,宣君星 대구효성가톨릭대학교 1995 연구논문집 Vol.51 No.1

This article is to provide us, from the points of ecclesiastical, political and legal history, with the initial aspect of the growth of the Roman Catholic church and the establishment of the Pope's supremacy over all the Christians who lived in the west of Roman Empire, from the end of the Roman civilization to the death of Theoderic(456?∼526), the king of the East-Goths. In the wake of its development the Roman Catholic Church had troubled with so many differentied religious sects and heresies such as Manicheans, Monophysists and Nestorians etc. And also the supreme authority of the pope, which was accepted from the most devout christian believers as the utmost important spiritual power to lead to the eternal 'kingdom of God' by encouraging them to live up to the sacramental and gospel life and by preserving the christian "pure" beliefs, had faced with the strong objections from the four Metropolitans or Patriarchs, especially from the Patriarch of Constantinople. In fact the pope's supremacy originated from the gospel, the Matt : 16∼18, saying that "You(=Petrus) are the rock with which I(=Jesus Christ) can build my church on earth. Therefore I will give you the power(or authority) to fasten or loosen them in the Heaven according as the sinners are fastening or loosening in the Earth." People has often called such a Christian gospel as the doctrine of "Key To The Heaven." Nowadays, therefore, the popes of the Roman Catholic Church are legitimately considered as an heir to the St. Peter's apostolate and the Vicar of Jesus Christ in the earth. The supreme powers of emperors and popes as well in the Middle Ages had respectively owned their areas of jurisdiction and as a result formed the unique phenomenum like the relation of state and church, which had influenced on the ecclesiastical, political and legal lifes during the middle ages. And henceforth many European historians has named such a dual style in the constitutional and ecclesiastical life in the Middle Ages of Europe as the "Dual Monarchy" or "Two-Swords-Theory(=Zwei Schwerterlehre)." However, this admitted dual monarchial system during the Middle Ages had been surmounted by the advent of the modern, secular political and legal thoughts as the theory of monarchal sovereignty and the "reason of state"(=raison d'Etat), and by the outbreak of the Reformation and the religious wars in the early-modern Europe. In conclusion, we can say that the initial aspect of the Roman Catholic Church and its advocacy of the supremacy of the Roman bishops(=the Popes) from the and of the Roman Empire onwards was formed with difficulties, and that in this first stage of development of the Roman church such an unique phenomenum as the alleged relation of the state and the church was being in germ and later the dual constitutional life of secular and spiritual one would be made.

혈압에 영향을 주는 식이요인 중에서 섭취지방이 상당히 중요하다는 것은 일찍부터 거론이 되어왔으며, 식이지방 중에서 다불포화지방이 혈압을 낮추는 효과가 있다고 대체적으로 요약할 수 있겠다. 그러나 다불포화지방산의 종류에 따라서도 차이가 지적되고 있으며, 그 중에서 n-6계열의 식물성다불포지방과 n-3계열의 어유 다불포화지방간의 비교가 최근 10년간 많은 연구의 대상이 되어왔고, eicosapentaenoicacid(EPA)와 docosahexaenoic acid(DHA)가 주다불포화지방산이 되는 어유가, 오랫동안 필수지방산으로 중요시해 왔던 식물유의 linolic acid보다 혈압강하작용이 크다는 결과들이 주목을 끌고 있다.
