By studying from Chun Kuk are(戰國時代) to Chung area(淸代), I could find some conclusion as follows. 1. It was Chun Kuk area(戰國時代) that was shown some signs of forthcoming activity of theory of Ki Kyung Pal Maek(奇經八脈). In that time, Hwang Jae Nae Kyung(黃帝內經) had been written. That book made a important role for foundation of theory of Ki Kyung Pal Maek(奇經八脈), but it hadn't sufficient contents in some parts. 2. The theory of the Ki Kyung Pal Maek (奇經八脈) had been developed in Jin Han area(秦漢時代), Nan Kyung(難經) had been written in the area, Nan Kyung(難經) had been the first book which had referred to name and physiology of Ki Kyung Pal Maek(奇經八脈) and it also had mentioned about course, function, and pathology of that in simple manner. 3. In Yang Jin are and Su Dang area(兩晋 및 隋唐時代), Maek Kyung(脈經) and Hwang Jae Nae Kyung Tae So(黃帝內經太素) had been written Maek Kyung(脈經) had been the first book which had referred to pathology of Ki Kyung Pal Maek(奇經八脈) by Maek Jin(脈診) in detail, and it had affected on such books like Tae Pyung Seoung Hveu bang (太平聖惠方) and Ko Kum Yeu Tong Dae Chon(古今醫統大全). Hwang Jae Nae Kyung Tae So(黃帝內經太素) had mentioned about course, function, and pathology about Ki Kyung Pal Maek(奇經八脈) in most detail at that time, and it also had referred to that of such books like Myung Dang(明堂) and Ku Khoun Kyung(九卷經) which do not exist in present. Because of these point, Hwang jae Nae Kyung Tae So(黃帝內經太素) is evaluated an important book of theory of Ki Kyung Pal Maek(奇經八脈). 4. In Song area(宋代), Seung Jae Chong Rok(聖濟總錄) had been written. Seung Jae Chong Rok(聖濟總錄) first mentioned about meeting between Ki Kyung Pal Maek(奇經八脈) and Sip I Jong Kyung(十二正經), so this book helped development of theory of Ki Kyung Pal Maek(奇經八脈) of Kum Won area(金元時代). 5. In Kum Won area(金元時代), Dong In Su Hyul Chym Ku Do Kyung(銅人腧穴針灸圖經) had been written. Dong In Su Hyul Chym Ku Do Kyung(銅人腧穴針灸圖經) made a important role of theroy of Im Meak(任脈) and Dok Meank(督脈). Sip Sa Kyung Bal Hyui(十四經發揮) was superior to other books which had been referred to theory of Ki Kyung Pal Maek(奇經八脈) at that time. Also Sip Sa Kyung Bal Hyui(十四經發揮) more mentioned about meeting between Ki Kyung Pal Maek(奇經八脈) and Sip I Jong Kyung(十二正經) than that of Seung Jae Chong Rok(聖濟總錄), so this book helped dvelopment of theory of Ki Kyung Pal Maek(奇經八脈). 6. In Myung area(明代), Ki Kyung Pal Maek Ko(奇經八脈考) that had almost accomplished theory of Ki Kyung Pal Maek(奇經八脈) had been written. Ki Kyung Pal Maek Ko(奇經八脈考) was the best book more than any other book that had been mentioned about theory of Ki Kyung Pal Maek(奇經八脈) in three ways as follows. 1) It is Ki Kyung Pal Maek Ko(奇經八脈考) that mentioned about near similar manner of modern course and physiology of Ki Kyung Pal Maek(奇經八脈). 2) Ki Kyung Pal Maek Ko(奇經八脈考) mentioned about pathology and treatment of Ki Kyung Pal Maek(奇經八脈) in detail more than any other book. 3) Ki Kyung Pal Maek Ko(奇經八脈考) emphasized on relationship between Ryun Kong(鍊功) and Ki Kyung Pal Maek(奇經八脈).

Purpose : Early detection and intervention of hearing impairment is believed to improve speech and language development and behavior of children. The aim of this preliminary study was to determine the prevalence of hearing impairments, and to identify the association of risk factors relating to refer response in high risk neonates who were screened using distortion product otoacoustic emissions (DPOAE). Methods : The subjects included 871 neonates who were admitted to the neonatal intensive care unit of the Pediatric Department in Soonchunhyang University Bucheon Hospital from May, 2001 to December, 2004. They were screened using DPOAE. Based on DPOAE, we divided the neonates in two groups : 'Pass' and 'Refer'. The differences in risk factors between the pass group and the refer group were analyzed. Results : The incidence of the refer group was 12.1 percent(106 out of 871). The bilateral refer rate was 5.4 percent(47 out of 871). And the unilateral refer rate was 6.7 percent(59 out of 871). Gender, birth place, family history of hearing loss, small/large for gestational age, obstetrical factor, hyperbilirubinemia and use of gentamicin were not statistically related to the refer rate. Statistically related to refer rate were birth weight, resuscitated neonates, Apgar score, craniofacial anomaly, mechanical ventilator application, sepsis, using of vancomycin(P<0.05). The prevalence of hearing impairment (${\geq}60dB$) in this study was 2 percent(18 out of 871). Conclusion : This study showed a higher prevalence of hearing impairment in high-risk neonates. Thus neonatal hearing screening should be carried out in high-risk neonates.

In Korea, the number of crash accident victims per 100,000 population is three times higher than the average of OECD. In particular, 60% of it occurs on the community road. Thus, this study intends to analyze the causes of such accidents through a pedestrian and vehicle traffic survey. The purpose is to establish practical safety enhancement measures for community roads. In recent years, lots of changes have occurred in the pedestrian environment. A traffic survey shows that 65% of pedestrians walk on the right and 17% of people use smart-phones while walking. An eye camera experiment shows that the operation load of drivers on the community roads is more than 4 times higher than those in urban roads. According to a speed survey, 62% of vehicles drive at 30km/h or above. The characteristics of accidents on community roads are as follows. First, the ratio of accidents on the edge of the road is 2.3 times as high as those on other roads. Second, when people walk on the right, the ratio of accidents is 2.5 times as high as that of walking on the left. Third, it becomes more dangerous when people cross the road from the right to the left. The majority of accidents is caused by unsafe driving (84.4%). When a vehicle makes a left turn, the likelihood of accidents is 2.3 times as high as those caused by a right turn. The ratio of accidents caused by vehicles going backwards is 14% among all accidents. In community roads, the focus of drivers should be at least 4 times higher than those on urban roads. Thus, walking in the opposite direction of vehicles and careless behaviors are highly likely lead to accidents.

The study aimed to evaluate cancer damage cost due to risk from benzene inhalation. We performed health risk assessment based on US EPA guideline to estimate annual population risk in Ulsan metropolitan city. Also, we estimated a willingness-to-pay amount for reducing a cancer mortality rate to evaluate a value of statistical life. We combined the annual population risk and the value of statistical life to calculate the cancer damage cost. In the health risk assessment, we applied the benzene unit risk ($2.2{\times}10^{-6}{\sim}7.8{\times}10^{-6}$) in the US EPA'S Integrated Risk Information System to assess the annual population risk. Average concentration of benzene in ambient air is $7.88{\mu}g/m^3$(min: 1.16~max: $23.32{\mu}g/m^3$). We targeted an exposure population of 516,641 persons who aged over 30 years old. Using a Monte-Carlo simulation for uncertainty analysis, we evaluated that the population risk of benzene during ten years in Ulsan city is 2.90 persons (5 percentile: 0.32~95 percentile: 9.11persons). And the monthly average WTP for 5/1,000 cancer mortality reduction during ten years is 14,852 Won(95% C.I: 13,135~16,794 Won) and the implied VSL is 36 million Won(95% C.I: 30~40 million Won). Cancer damage cost due to risk from benzene inhalation during 10 years in Ulsan city is about 104 million Won(5 percentile: 13~95 percentile: 328 million Won). Health benefit cost to reduce a cancer mortality risk of benzene is about 50 million Won is Ulsan metropolitann city. But, it is very important that this cost is not for all health damage cost of cancer mortality in some area. We just recommended a model for evaluating a cancer risk reduction, so we must re-evaluate an integrated application of total VOCs damage cost including benzene.

Purpose : As hearing ability affects language and cognitive development, early detection and intervention of congenital hearing defects is very important. We analyzed the result of newborn hearing screening using automated auditory brainstem response and estimated the incidence of congenital hearing defects in newborn infants in Korea. Methods : Hearing screening tests were done on 7,218 newborn infants who were delivered at Cheil General Hospital from July 1, 2004 to June 30, 2005. The first screening test was done on the second day of life with automated auditory brainstem response(AABR) using $ALGO{\bigcirc}^{(3)}$ Newborn hearing screener($Natus^{(R)}$ Medical Incorporated, San Carlos, USA) with 35 dB sound level. The newborn infants who did not pass the initial screening test took the second screening AABR test before discharge from the nursery. Infants who did not pass these screenings at the nursery were followed up at the Department of Otorhinolaryngology, Samsung Seoul Hospital. Results : Total 7,218 infants(83.3 percent of total 8,664 live births of the Cheil General Hospital) were screened in the nursery, and 55 of them failed to pass the newborn screening. Among 55 infants who were referred, six were lost during follow-up, and 14 were confirmed as hearing impaired. Six of them(42.8 percent) do not have any risk factors for hearing impairment. We can estimate that the incidence of hearing defects is about 1.9-2.8 per 1,000 live births. Conclusion : Automated auditory brainstem response is an effective tool to screen the hearing of newborn infants. Congenital hearing loss is more frequent than metabolic diseases on which screening tests are available in the newborn period. About 40 percent of infants who have hearing defects do not have any risk factors for hearing impairment. Therefore, universal newborn hearing screening must be recommended to all neonates.

Purpose: The purpose of this study was to analyze the characteristics of the injuries of the national elite Taekwondo players with the best performance in the international championship competition. Materials and Methods: Fifty-two athletes who got the injury in the 2011 Gyeongju World Taekwondo Championship competition were included in this sturdy. 950 members of national team of 146 countries participated in this game, 1,063 matches were performed. We analyzed the characteristics of the injuries such as injury rate by gender, age, weight class, injured region and injury type. Results: Fifty-two athletes of 950 athletes in 1,063 matches got injured and injury rate was 5.47 per 100 participants and 24.47/1,000 athlete-exposures. Injury rate of female athletes was higher than mail, but there was no significant statistical difference (p=0.512). Injury rate of over 30 years old was 17.39 per 100 participants, and injury rate of over 87 kg in male weight class and 68 to 73kg in female weight class were highest than other groups, but there was no significant statistical difference (p=0.838). Overall injury rate of the lower extremity was 13.17/1,000 A-E, higher than upper extremity or head and neck or trunk, but injury rate of the hand was 5.17/1,000 A-E, highest as a specific injured region, followed by the knee, 4.70/1,000 A-E (p=0.714). Injury rate of the sprain was 10.81/1,000 A-E, highest as an injury type, the second most common injury type was the fracture, 5.40/1,000 A-E in men, and was the contusion, 9.63/1,000 A-E in women (p=0.033). As one of the most serious injury, 4 of 8 fractures were occurred in hand. Conclusion: Overall injury rate of the elite Taekwondo players in 2011 Gyeongju World Taekwondo Championship was 5.47 per 100 participants and 24.46 per 1,000 athlete exposures. Although the most common type of injury was the sprain of the knee and ankle, the fractures were more commonly occurred in hand.

The acupuncture and moxibustion documentary characteristics of the "Dong-insuhyeolchimgudogyeong(銅人腧穴鍼灸圖經)" can be summarized into 5 parts such as the following. 1. The Index of Books lists the author of "Dong-indogyeong" as 'Wang-yuil(王惟一)' in some and 'Wang-yudeok(王惟德)' in others. Of these 'Wang-yudeok' is the name in the printed book and 'Yuil(惟一)' was the name it was changed into in order to make it different from the emperor Jinjong(眞宗) of the Song dynasty. Also, the sequence differs greatly among the original editions and sometimes even conflicts within itself, which makes very likely the possibility that the author of this book is not just one person, and that Wangyuil is just the main editor or screener. 2. The original printed edition of the Song(宋) dynasty has 3 volumes and the Cheonsoeng Seokgak(天聖 石刻) of the Song dynasty also has 3 volumes, but 'Hyeolsudosu(穴腧都數)', 'Sumyeongdanggyeolsik(修明堂訣式)', and 'Pichimgugyeol(避鍼灸訣)' were added to the 3rd volume. Of these three 'Pichimgugyeol(避鍼灸訣)' explains the 'Chimgupigijido(鍼灸避忌之圖)' of the 2nd volume in writing, 'Sumyeongdanggyeolsik(修明堂訣式)' explains the three human drawings from the front, side and lying down views in writing and was used to make bronze figures. 'Hyeolsudosu(穴腧都數)' was possibly used to draw acupuncture points when making bronze figures. During the Daejeong(大定) era of the Keum(金) dynasty Jinssi(陳氏) from the Pyeongsuseobang(平水書坊) revised this book and carved it into 5 volumes, and of those the 1st and 2nd volumes have characters that are very different from those of the rubbed copy of the stone carvings[石刻 拓本] from the Myeong(明) dynasty, which shows that it was taken from another book and not from the original text. The 3rd volume has added content from the stone carvings about accupuncture and moxibustion contraindication(鍼灸禁忌). During the Myeong dynasty the 3 volumes of the "Dong-indogyeong(銅人圖經)" were carved on wood based on the Jungtong Sukgan(正統 石刻), and there were many reprints with the contents that are almost all the same, but the order of the original edition were not all the same. When analyzed from many angles, the original printed copy was carved after the Jungtong(正統) of the Myung dynasty. 3. The content on transport points[輸血] in "Dong-indogyeong(銅人圖經)" comes mostly from books like "Oedae(外臺)" 'Myeongdang(明堂)', "Taepyeongseonghyebang(太平聖惠方)" 'Chimgyeong(鍼經)', "Yeongchugyeong(靈樞經)", Wangbing(王冰)'s annotation of "Somun(素問)", "Cheon-geumyobang(千金要方)" 'Chimgu(鍼灸)', and does not have much new content added by Wang-yuil(王惟一). However when Wang quotes past documents, little is summarized, some are edited and most do not have their origin indicated(the titles of other books quoted in the book are to give some supplementary explanation or are copied from another book). 4. There are many mistakes Wangyuil made in using documents and doing historical research and they can be seen in two fields. One is that he did not fix the errors of past documents, and the other is that he did not know the sequence of past documents or did not understand the meaning of the text. 5. The content Wangyuil newly added can mostly be seen in the few annotations and aneo(按語) under the original 'Geumbu(今附)'('Sinbu(新附)'). In order to see Wang's scholarly ideas and achievements we must rely on this part and the meridian entry of the transport points[輸血歸經] in the first part of the book. However we must not give credit to Wang for work that was done by former generations.

The purpose of this study was to evaluate results of cervix cytology screening in the community and to determine the risk factors of cervical abnormality. Branch of Daejeon city and Chungnam Province, The Planed Parenthood Federation of Korea had conducted cervical cancer screening of 146,848 married women in Chungnam province from 1995 to 1999. Cervical cancer screening was Pap smear using cytolgic brush swab by trained nurse. Women who had abnormal finding of 1st Pap smear screening were followed re- examination and 2nd close examination. Crude prevalence rate of cytologic abnormalities for 1st screening results was 0.63% in 1995- 1999(1995 0.68%, 1996 0.59%, 1997 0.70%, 1998 0.56%, 1999 0.62%). Crude prevalence rate of above class III for 1st screening results was 0.61%, but crude prevalence rate of above class III for the results of re- examination and 2nd close examination was 2.2/ 1000. The false-positive rate of class III, IV and V for positive findings were defined above class II(cervicitis) results were 52.6%, 26.9% and 19.0%, respectively. And the false- positive rate of class III, IV and V for positive findings were defined above class III(dysplasia) results were 75.3%, 46.2% and 47.6%, respectively. Major predictors of risk factors for abnormal results of cervix screening on the multiple logistic regression were age, educational attainment and living area. The false-positive rate of cervix cytology screening in the community were highest result so cervix cytology screening should be improve for better diagnostic power. And the finding of logistic regression would be understand within the limit of experimental trials on the relationship between cervical disease and risk factors.

Purpose : Children with acute colonic diverticulitis(ACD), can be misdiagnosed with acute appendicitis. Methods : We reviewed 15 cases of ACD during five years, from January 1998 to June 2002 retrospectively. Results : Most patients(80%) with ACD in children presented with right lower quadrant pain. The primary diagnosis on admission was mostly acute appendicitis(87%), and all ACD in children occurred in the right colon. Fourteen patients were managed by conservative treatment including antibiotics. A follow-up study was performed in 15 patients. There were symptomatic recurrences in two patients, but no significant complication was noted. The frequency of ACD was 11.7 per 1000 acute appendicitis. Conclusion : ACD in children can mostly be cured by conservative treatment. It is prudent to choose the management through the diagnostic work up, including abdominal sonography and computed tomography, because there was no significant difference of clinical findings between ACD and acute appendicitis.

Purpose : This study was performed to investigate the epidemiologic feature of aseptic meningitis in Pohang city for 6 years from 1997 to 2002. Methods : We reviewed the clinical records of 1,839(1,138 male and 701 female) aseptic meningitis patients who had been admitted to 3 general hospitals in Pohang city from 1997 to 2002. Results : 1,750 cases(1,078 male and 672 female) were selected as aseptic meningitis by reviewing clinical records. The ratio of male to female was 1.6 : 1. Aseptic meningitis occured in children of all age groups, and the prevalent age group was different by year. The most common developed month was June(31.3%), and 84.2% of cases were focused from May to August. The time from the initial manifestation to hospital admission was $4.19{\pm}2.96$ (median 3 days). Conclusion : We were performed to investigate the epidemiologic feature of clinical records of Aseptic meningitis pediatric patients who had been admitted and treated to 3 General hospitals in Pohang city from 1997 to 2002. We have to keep up Our study for consideration of the basic of Aseptic meningitis epidemiology and long term control is necessary to prevention the impact of Aseptic meningitis because Aseptic meningitis pediatric patients were continuously recorded by Epidemiological annual report in Pohang city.
