Background : Measurement of the $FEV_1$ and PEFR in COPD patients is a significant indicator of the disease severity, the response to treatment and the acute exacerbation. However, it is not known if PEFR can be used to determine the severity of COPD because the agreement between PEFR and $FEV_1$ in COPD patients is not well known. Methods : From September, 2003 to August, 2004, 125 out patients with COPD who were treated at the pulmonary clinic in KonKuk University Hospital were enrolled in this study. The $FEV_1$ and PEFR of each patient were measured and all the data was analyzed using SPSS. Results : The average predicted $FEV_1$ % and PEFR % was $56.98{\pm}18.21%$ and $70{\pm}27.60%$, respectively. There was linear correlation between the predicted $FEV_1$ % and predicted PEFR %. There was no correlation between age of the COPD patients and the predicted PEFR %. There was correlation between dyspnea, which is a subjective symptom of the patients, and the predicted PEFR %. Conclusion : In COPD patients, the classification of the severity by PEFR tends to underestimate the state of the disease compared with the classification of the severity by the $FEV_1$. Therefore, the classification of the severity by PEFR should be interpreted carefully in patients with severe symptoms. Once the classification of the severity has made, the follow-up examination may use the PEFR instead of the $FEV_1$.

Objectives : This study was designed to research whether transcranial doppler ultrasound(TCD) can yield a suitable diagnosis or prognosis for dizziness. Methods : To evaluate the blood flow, we measured the mean velocity(Vm), peak systolic velocity(Vs) and pulsatility index(PI) of the middle cerebral artery(MCA), vertebral artery(VA) and basilar artery(BA) in 54 dizziness patients and 44 normal subjects. To investigate the difference between dizziness patients and normal subjects, we selected 54 dizziness patients diagnosed normal by Brain MRI, and 44 normal subjects who did not have any symptoms of hyperlipemia, hypertension, diabetes melitus, heart disease, or smoking, diagnosed normal by Brain MRI. 30-69 year olds were divided into 30-49 year olds, 50-59 year olds and 60-69 year olds. Results : In normal subjects, there was a significantly higher Vm, Vs in the MCA and BA, and Vs in the VA of female subjects, and there was a significant difference in PI in the MCA and BA increasing with age. In comparison with normal subjects, dizziness patients had a significantly lower Vm in the BA. Male dizziness patients had significantly lower PI in the MCA. 30-49 year olds had significantly lower Vm in the BA. Conclusions : The significant difference in blood flow velocities in the BA between dizziness patients and normal subjects suggests that dizziness is related to blocking of blood flow in the BA and that diagnosis and prognosis can be made through TCD. More detailed study of dizziness patients will be needed.

Purpose: This study was conducted to analyze the clinical manifestation and natural course of benign transient hyperphosphatasemia (BTH) in children. Methods: A total of 17 children diagnosed with BTH between June 2006 and July 2007, were included in this study. Clinical records and laboratory tests were analyzed retrospectively for all children. Results: The mean age of the patients was $26.9{\pm}13.8$ months (range: 9 to 49 months). Nine of the 17 BTH cases (52.9%) occurred in patients that had previously suffered from infectious diseases. While the patients were suffering from BTH, the mean serum level of alkaline phosphatase (ALP) was $2,500.2{\pm}1,165.1$ U/L, however, these elevated serum ALP levels normalized within 7 weeks of recovery in all cases. In addition, a seasonal peak in the onset of BTH was observed from September to December. Further, the measurement of ALP isoenzymes in 7 of the patients with BTH, revealed a marked elevation of bone fraction. Conclusion: It is important for pediatricians to understand the clinical manifestation and benign course of BTH to avoid unnecessary diagnostic evaluation in children showing a transient increase in ALP activities.

The purpose of this study is to suggest vegetation management method as the cultural landscape forest of Dongbaek Island which is the district monument. The study area was $20,000m^2$ around the peak area in management as the nature sabbatical area. Vegetation structure type was classified with the criteria of topography, vegetation, management and the management plan was derived from the vegetation structure analysis according to the types. Vegetation structure types were Management-Camellia japonica, Non-management-Eurya japonica, Non-management-Rugged area-Eurya japonica. As the result of vegetation structure, Pinus thunbergii dominated in canopy layer and Camellia japonica and Eurya japonica dominated in Type I and in Type II and III, respectively. Especially, Machilus thunbergii as the climax species in the warm temperate forest were distributed centering shrubs, and as the result of distribution of diameter of breast height, middle size of Celtis sinensis and Machilus thunbergii were distributed in type I, II. Machilus thunbergii were distributed in range of 4 to 44 individuals through the all types. Mean age of canopy layer was 66 year-old and sub-canopy layer was 22.9 year-old. Shanon's species diversity was analysed from 0.5472 to 0.8646. As the vegetation management direction of Dongbaek island, managed Camellia japonica forest was suggested to maintain the regular management and non-managed Eurya japonica forest was required to remove the Eurya japonica and plant the Camellia japonica. In case of non managed Eurya japonica forest in rugged area, vegetation succession was required to laurel forest.

Purpose: Deficits of the respiratory chain are reported to be the major cause of Leigh syndrome is said to be the underlying causes. The need for biochemical diagnosis to draw more accurate diagnosis or prognosis to support treatments is rapidly increasing. This study tried to analyze the aspects of clinical characteristics and biochemical diagnosis of mitochondrial respiratory chain complex (MRC) defect in Leigh syndrome, using methods of biochemical enzyme assay. Methods: We included total number of 47 patients who satisfied the clinical criteria of Leigh syndrome and confirmed by biochemical diagnosis. All those patients went through muscle biopsy to perform biochemical enzyme assay to analyze MRC enzyme in order to find the underlying cause of Leigh syndrome. Results: MRC I defect was seen in 23 (48.9%) cases taking the first place and MRC IV defect in 15 (31.9%) following it. There were 9 (19.2%) cases of combined MRC defect. Combined cases of type I and IV were detected in 7 (14.9%) patients while type I and V in 2 (4.3%). The onset age of symptom was less than 1 year old in 28 (59.6%). The most common early symptom, observed in 23 (48.9%), was delayed development, but there were other various neurological symptoms observed as well. In regard with the disease progression, 35 (74.5%) patients showed slowly progressive course, the one that progressed continuously but slowly over 2 years of period. As for Maximum motor development, 22 (46.8%) were bed-ridden state, most of them suffering serious delayed development. Patients showed various symptoms with different organs involved, though neuromuscular involvement was most prominent. Delayed development was seen in all cases. Multifocal lesion in brain MRI study was seen in 36 (76.6 %) cases, taking a greater percentage than 11 (23.4%) cases with single lesion. In MR spectroscopy study, the characteristic lactate peak of mitochondrial disease was identified in 20 (42.6%) patients. Conclusions: Further analysis of clinical and biochemical diagnosis on more extended group of patients with Leigh syndrome will enable us to improve diagnostic precision and to understand the natural course of mitochondrial disease.

Today we seem to be flooded with digital culture as the age of information has reached its peak. As fusion culture has been generalized, in which the arts and culture of the East and the West are in harmony, and quality of life has been improved, people are enjoying more abundant cultural benefits than ever. In such a situation, we may lose the origin of our culture and disregard our traditional culture due to the mixture of cultures. In addition, it is necessary at this point to distinguish pure culture from mixed one and to re-illuminate the value of our original culture for the next generation. Therefore, the author took interested in Dongraeyaryu, a large-scale festival in Busan, which has been designated as an important intangible cultural property, and carried out a research for its continuous instruction and activation. among contents such as music, costume, dancing and stage properties that compose intangible cultural property, this study selected costume, which has significant visual effects and large differences in shape between old one and contemporary one, for development. By proposing modernized design of costume preferred by the new generation and in harmony with the masks, this study wished to narrow the generation gap, to direct young people's attention to the learning of tradition and to propose motives that activate the culture of local festival.

This research identifies the ingress to egress primary factors that causes a patient to receive delayed emergency medical care. This material was collected between February 1st to 28th, 1998. Research envolved 4,118 people who visited the college emergency medical center in Kyeongido Province, South Korea. Medical records were examined, using the retrospective method. to determine the length of stay and the main cause for waiting. Results are as follows : 1. The age group with the highest admission rate was 10 and under, approximately 1,394 (33.9%). Followed by an even distribution for ages between 11-50 at 10-15% for their respective ranges. The lowest admission rate was 50 years and above. 2. From the 4,118 records examined, 3,489 received outpatient treatment (84.7%); 601 were admitted for inpatient care (14.6%); 25 arrived dead on arrival (0.6%); and 4 people died at the hospital. 3. Between 7PM to 12AM, 42.9% were admitted to the EMC. The hours from 9PM to 11PM recorded the highest admission rate and 5AM to 8AM was the lowest From 8PM to 12AM, the most beds were occupied. 4. For most patients. the average length of stay was approximately 2.2 hours. By medical department, external medicine was the longest for 2.8 hours. Pediatrics was the shortest for 1.6 hours. The average waiting period for inpatient admission was 2.6 hours. Inpatient admission for pediatrics and external medicine was 3.4 hours and 2.2 hours respectively. 5. Theses are primary factors for delay at EMC: 1) pronged medical consultations to decide between inpatient versus outpatient treatment, and delaying to be inpatient, 2) when you call physicians they are delayed to come 3) Understaffing during peak or critical hours, 4) Excessive consulting with different medical departments, 5) some patients require longer monitoring periods, 6) medical records are delayed in transit between departments, 7) repeated laboratory tests make delay the result, 8) overcrowded emergency x-ray place causes delay taking x-ray and portable x-ray, 9) the distance between EMC and registration and cashier offices is too far. 10) hard to control patient's family members. The best way to reduce EMC waiting and staying time is by cooperation between departments, both medical and administrative. Each department must work beyond their job description or duty and help each other to provide the best medical service and satisfy the patient needs. The most important answer to shortened the EMC point from ingress to egress is to see things from a patient point of view and begin from there to find the solution.

The Sesong Formation, mixed carbonate-siliciclastic deposits of late Middle Cambrian (Series 3) to Furongian in age, in the Taebaeksan Basin shows the Steptoean Positive Carbon Isotope Excursion (SPICE) with the ${\delta}^{13}C$ values ranging from 1.14 to 2.81‰ in the approximately 15-m-thick stratigraphic interval. The SPICE in the Sesong Formation occurs in the lower part of the Paibian Stage which contains trilobite biozones of the Fenghuangella laevis Zone, Prochuangia mansuyi Zone and the lower part of the Chuangia Zone. The Sesong Formation is composed of six lithofacies including laminated mudstone, nodular shale, laminated sandstone, massive sandstone, limestone conglomerate, and limestone-shale couplet facies. The Sesong Formation is known to have been deposited in the outer shelf below storm wave base. The SPICE occurs in the stratigraphic interval associated with highstand systems tract, correlative conformity and transgressive systems tract of the Sesong Formation. The peak carbon isotope value in the SPICE may coincide with the correlative conformity formed by relative sea-level fall. The occurrence of the SPICE in the Sesong Formation suggests that the SPICE can be used as a tool of global correlation for the successions of mixed carbonate-siliciclastics which lack fossils.

The Song Dynasty(宋代) period gained the summit in the developmental phase of the history in pediatrics. In 1076, Taeuiguk(太醫局) was founded and Sobangmaek(小方脈) was the one of nine branch in Taeuiguk(太醫局). As a result, educational agency and system was arranged in the field of pediatrics. At the same time, pediatrics have furnished with foundation to develop independent field in medical science. Especially, Byeonjeungnonchi(辦證論治) system is established in pediatrics science according to the compilation of "Soayakjeungjikgyeol(小兒藥證直訣)" by Jeoneul(錢乙). Children's doctors, Jeoneul(錢乙), Jinmunjung(陳文中) and Donggeup(董汲) arranged clinically theories, so they made that age the peak of the pediatrics. Looking at the developmental part of theory in pediatrics of the Song Dynasty period, Jeoneul(錢乙), who was the representative children's doctor in Song Dynasty period, insisted that children had formed Ojang-yukbu(五臟六腑) in the physiological part but they were not perfect like adult's. Therefore they had to consider the poor part in children's body, and then they had to cure them. 'Byeonjeung(變蒸)' was considered to be normal physiological phenomenon. Also he insisted that Yukeum(六淫), 'Pung, Han, Seo, Seup, Jo, Hwa(風, 寒, 暑, 濕, 燥, 火)' and 'Gyeong, Pung, Gon, Cheon, Heo(驚, 風, 困, 喘, 虛)' are the main cause of the children's five vital organ's pathology Like this, his academic thought, which lay emphasized on children's spleen and stomach and Ojangbyeonjeung(五臟辦證) main principles, affected on doctors, Donggeup(董汲), Yeomhyochung(閣孝忠), Yubang(劉肪), Jang-wonso(張元素), Idong-won(李東垣), Manjeon(萬全). Bangje(方劑) fields of pediatrics had developed so fast and "Taepyeongsunghyebang(太平聖惠方)" contained about 2689 kinds of children's prescription. According to this, there are so many kinds of medicinal shape, for example 'Hwan, San, Go, Dan(丸, 散, 膏, 丹)', which cured children' s disease. Through this, we find that the shape of medicine about the children's diseases had developed to the more simple direction, taking account of the children's clinical trait.

This research was carried out in order to make clear population and community structure of Berchemia berchemiaefolia forest surveyed from October 1998 to October 2004 which was located in Janggok-Ri Gunwi-Gun, Kyungpook province. B. berchemiaefolia community was classified into 3 groups such as Picrasma quassioides group, Carex ciliata-marginata group and Typical group using ZM methods. In case of floristic composition structure according to crown stories, B. berchemiaefolia occupied 42.82%, 34.43%, and 5.28%, in tree layer, subtree layer and shrub layer, respectively. Importance value of Quercus variabilis, Platycarya strobilacea and Quercus serrate species was generally high. Species diversity of Picrasma quassioides group indicated 1.6669 which was highest value among the 3 vegetation groups. Population of B. berchemiaefolia showed overall the structure of reverse J type in DBH class showing the peak between 6 cm and 10 cm and reached 14 meters in height class, and the age structure of the population ranged from 11 years to 60 years showing regular distribution type. Stump sprout or/and epicormic branch made numerous stems around original stump of previous generation which was considered to be cut and disappeared by residents. Seedlings or/and saplings of B. berchemiaefolia were intensively occurred in the opened areas of forest road. Those things could be certainly considered to establish management plan of B. berchemiaefolia forest.
