        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.

        3분과 : 가선집재작업에서의 작업 생산성 및 비용 분석

        한원성 ( Won Sung Han ),한한섭 ( Han Sup Han ),김남훈 ( Nam Hun Kim ),차두송 ( Du Song Chu ),조구현 ( Koo Hyun Cho ),민도홍 ( Do Hong Min ),권기철 ( Ki Cheol Kwon ) 한국임학회 2014 한국산림과학회지 Vol.103 No.1

        본 연구에서는 임목수확작업에 사용되는 집재기계의 작업효율성을 분석하여 경사가 급한(20° 이상) 작업조건에 적합한 가선계 집재기계를 선정하는데 기초 정보를 제공하고자, 타워야더(RME-300T), 트랙터부착형 집재기(일명: 춘천집재기), 트랙터윈치(FARMI) 등에 의한 집재작업에서의 작업생산성 및 비용을 비교 분석하였다. 평균 흉고직경이 20 cm, 집재거리 60 m, 가로집재거리 10 m, 그리고 기계이용률이 70%인 동일한 작업 조건에서 작업이 이루어질 경우, 타워야더의 1일 집재작업 생산성은 33.04 m3/일, 트랙터부착형 집재기는 38.47 m3/일, 그리고 트랙터윈치는 14.17 m3/일으로 분석되었으며, 이에 따른 집재작업비용은 각각 25,105원/m3, 20,520원/m3, 37,835원/m3으로 나타났다. 동일한 작업조건에서 집재거리에 따른 각 집재기계별 작업효율성을 비교하였을 경우, 집재거리가 40 m 이내로 짧을 경우에는 트랙터윈치에 의한 집재작업이 효율적이며, 40~140 m의 집재거리에서는 춘천집재기가, 140 m 이상의 장거리 집재작업에서는 타워야더가 가장 효율적인 것으로 나타났다. 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.

        강승원(Seung Won Kang),박천호(Chun Ho Pak),조용성(Yong Sung Cho) 한국원예학회 2007 원예과학기술지 Vol.25 No.3

        관비재배와 저면관수인 ebb & flow, C-형강의 재배방식에 따른 고품질분화 생산을 위한 재배농가의 경제성을 분석하였다. 이를 위해 화훼농가의 비용구조를 분석하였고 자본 회수기간 및 내부수익률의 추정, 관수에 따른 인건비 절감 효과를 분석하여 재배방식에 따른 경제성을 비교하였다. 10a(991.7m²) 규모의 자동온실에 대해 관비재배방식을 선택한 시클라멘 재배농가의 총 비용은 9,993.8만원으로 추정되며, 이 중 시설비는 74%(7,410만원)를 점하고 연간 2,583.8만원의 경영비를 지출할 것으로 예상된다. 반면, C-형강방식을 선택한 재배농가는 초기 시설비용으로 약 8,520.0만원(총비용의 약 70%)을 지출하고, 매년 경영비로 3,597.0만원을 지출할 것으로 추정된다. 한편, 투자자금에 대한 자본회수 기간을 분석한 결과 10a 규모의 자동온실에서 시클라멘을 재배하는 농가에서 관비재배방식 혹은 C-형강방식을 선택할 경우에는 초기시설투자비 회수기간이 약 4 년 정도 소요될 것으로 예측되며, ebb & flow 방식을 선택할 경우에는 약 5년 정도의 시간이 소요될 것으로 예상된다. 또한, 내부 수익률을 추정한 결과 ebb & flow시설과 C-형강시설을 5년과 6년씩 사용한다고 가정할 경우, ebb & flow시설의 내부 수익률은 각각 9%와 14%로 나타났고, C-형강시설의 경우에는 각각 13%와 17%로 나타나 시중의 저축성예금 수신금리 4.82%와 비교하여 경제성이 높은 것으로 분석되었다. Economical efficiency for production of high quality-potted plants was analyzed by types of irrigation system such as conventional fertigation, ebb & flow, and C-channel as subirrigation systems. After cost structure was analyzed, payback period of capital, internal rate return (IRR), and effects of reduced labor cost were estimated. The gross cost of cyclamen-producing farmers using hydroponic systems in automated greenhouses (10a) was about 100 million won. Of the gross cost, installation and operation costs occupied 74% and 25%, respectively. In the C-channel subirrigation system, gross cost was 120 million won approximately. Installation and operation costs occupied 70% and 30%, respectively. Payback period of capital was 4 years for fertigated irrigation and C-channel subirrigation system, whereas it was 5 years for ebb & flow. IRR of ebb & flow and C-channel subirrigation systems was higher than the interest rates of 4.82%, indicating economic efficiency.

        Objectives: This study was conducted to investigate economic feasibility of operating Regional Cardiocerebrovascular Centers using cost-benefit analysis. Methods: The current study assessed cost and benefit data collected from nine hospitals which were designated as Regional Cardiocerebrovascular Centers between 2008 and 2010. Results: The operation of Regional Cardiocerebrovascular Centers reduced mortality rate and length of stay due to acute myocardial infarction and stroke and also decreased disability occurred after stroke. The total calculated cost of operating nine Regional Cardiocerebrovascular Centers was 19.85-22.30 billion won and the minimum benefit calculated was 23.98 billion won. Applying the maximum cost and the minimum benefit, the net benefit was 1.68 billion won, which is estimated to 190 million won per Regional Cardiocerebrovascular Center. Conclusions: The present study revealed that the operation of Regional Cardiocerebrovascular Centers was economically beneficial. The benefit would be larger if intangible benefit such as the long-term effects to community hospitals and enhancement of quality of life of patients and their families are considered.

      • 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.

        The purpose of this study is to explore what factors affects major choice of freshmen and how students evaluate about their choice. For this study, both studies of related literature and an empirical investigation have been carried. And frequency, crosstabs, and regression analysis are conducted to analysis determinate factors of major choice and students' satisfactions about major's choice. This survey provides that the experience of major related classes, the orientation of students' aim, the prospect of major are the major factors in the major choice. But the recommendation of families, the campus activities of major related, influence of speech and writing are not affect on the major choice. And students' satisfactions about major's choice are very high in the positive answers. Also the campus activities of major related, social recognition of job after graduation, data of major related as independent variables significantly affect satisfaction as dependent variables at 0.05 level. The limit of this study is that only the students of Gyeongju University are chosen as research sample, so generalization of conclusion should be restrained. Accordingly further studies consider the limits of current study carried.
