For the purpose of evaluating the effect of noise induced hearing loss on the blood pressure, a cross-sectional study was conducted in 481 manufacturing industrial workers in Pusan area consisted of 275 workers from noisier plant (over 90 dB(A), high exposed group) and 206 workers from less noisy plant (below 85 dB(A), low exposed group) from April to Decepmber in 1985. The summarized results were as follows; 1) The degree of hearing loss according to the audible frequency was most notable in 4,000 Hz. 2) The prevalence of hypertension was 14.8% in total examined subjects. And also in 40 dB(A) hearing lost workers, there was no significant difference between high exposed group as 15.5% and low exposed group as 15.8%. 3) In 3 models analyzed by multiple regression technique to obtain the complexed extents of risk factors related to the diastolic blood pressure, especially model III which contain age, body mass index, smoking, alcohol and family history of hypertension, duration of work, noise exposure level and degree of hearing loss in high exposed group was most remarkable compared to the others. 4) The most potential predictor related to the diastolic pressure in high exposed group was the degree of hearing loss. And the next were body mass index, familial history of hypertension and age in order. But in the case of low exposed group, the potential predictors were body mass index, age and familial history of hypertension.

This study was performed to identify the drug use and reuse relating characteristics and reuse relating factors in illegal drug users. Subjects consisted of 88 illegal drug users. Some of them were confined in a mental hospital or National Forensic Psychiatric Hospital located in Chung-nam province, others on attending a drug abuse prevention program in Seoul Probational Institute. Data were collected during the period from February 1, 2002 to February 25, 2002, and analyzed by SAS program. version 6.12. for Wilcoxon rank sum test, Pearson Correlation, Multiple regression. Results were as follows; 1. Drug use characteristics were as follows. $19.3\%$ was has drug family history and $20.7\%$ was has alcohol family history. Main drug was Phillopon$44.3\%$, inhalants $35.2\%$, LSD et al $22.7\%$. Drug use rate of months was everyday $31.2\%$, every other day $24.4\%$. 2. $100\%$ has experienced abstinence and reuse. Abstinence period was less than 12 months in $49.4\%$ and reuse period was less than 6 months in $58.6\%$. 3. Drug use and reuse characteristics related to general characteristics was identified as below. Abstinence period of male was longer than that of female. Person who have drug family history experienced more drugs and person who have family alcohol history started earlier. 4. Reuse periods was correlated with abstinence periods, age. And abstinence period was correlated with age and outcome that following reuse. 5. The multiple regression was used to identify the relating factors that influence reuse period and abstinence period. At the state of controlling abstinence period. inhalants users have 10.07 days shorter reuse period than others. And abstinence period had lengthened age, bad health status, early initiate age, and long reuse period.

Below are the reports arranged from the research of ${\ll}$XiFangZiMingTangJiuJing(西方子明堂灸經)${\gg}$, which appears in the research of the main issue. ${\ll}$XiFangZiMingTangJiuJing${\gg}$ was written during the Nan-song period, approximately between 1142~1194, and was probably completed between 1142~1148. This book is the very first book specific on the moxibustion theory which exists these days and also thoroughly contains the moxibustion theory. So it contains many documents of the moxibustion theory which are missing these days. Also it's possible that the illustration presented in this book followed ${\ll}$MingTangJing(明堂經)${\gg}$ of SunSiMiao(孫思邈). The way of arranging the GuiJing(歸經) of YuZue(兪穴) and deciding the location of acupuncturing(穴位) differs from reports given by other documents. As seen above, ${\ll}$XiFangZiMingTangJiuJing${\gg}$ has a consulting value on the moxibustion theroy(灸法), both in clinic and the research of documents. So we are looking forward that there would be a more profound research continuing in the future.

There were so many discussions about the importance of Ungi theory, but little about its application. But, in Korea, there is particular Ungi medical system. I studied the 25 organic constitutions and their prescriptions and concluded like below. In "Ounyukgihanihakbogam(五運六氣漢醫學寶鑑)", "Ounyukgihak(五運六氣學)", there are 25 organic constitutions, and each of them has its basic prescription. Like above, In "Ounyukgigeummoksuhwatosangsaengsanggeukbeop(五運六氣金木水火土相生相克法)", "Ounyukgigyeongheomcheobang(五運六氣經驗處方)", and "Jesaenglon(濟生論)", there are also 25 organic constitutions, and each has basic prescription. Moreover, there are so many prescriptions for diseases can often occur. I classified these as three groups, "Ounyukgihak(五運六氣學)" is groupⅠ, "Ounyukgihanihakbogam(五運六氣漢醫學寶鑑)" is Ⅱ, and the other books is Ⅲ, and compared each basic prescriptions. GroupⅠand Ⅱ use similar prescriptions, but groupⅢ doesn't. This Ungi medical system has little relation with "Somun(素問)". And I couldn't find the organic constitutions based on Ungi from other country's oriental medical book. 25 organic constitutions have much sameness in prescriptions. These prescriptions are used in real medical system, but not wide. Of course, it needs more research, but it has another position in oriental medicine.

In solid-liquid two phase flow, the knowledge of how descending solid particles affected by the presence of downstream wall is important. This work studies at what interstitial distance the velocity of a vertically descending sphere is affected by a downstream wall as a consequence of wall-modified hydrodynamic forces through a validated dynamic model. This interstitial distance-the hydrodynamic coupling distance ${\delta}_c-is$ found to decay monotonically with the approach Stokes number St which compares the particle inertia to viscous drag characterized by the quasi-steady Stokes' drag. The scaling relation ${\delta}_c-St-1$ decays monotonically as literature below the value of St equal to 10. However, the faster diminishing rate is found above the threshold value from St=10-40. Furthermore, an empirical relation of ${\delta}_c-St$ shows dependence on the drop height which clearly indicates the non-negligible effect of unsteady hydrodynamic force components, namely the added mass force and the history force. Finally, we attempt a fitting relation which embedded the particle acceleration effect in the dependence of fitting constants on the diameter-scaled drop height.

On the text of Yukgyeong(六經) in "Sanghanpyeon(傷寒篇) in Uihakyimmun(醫學入門)", we got some conclusion like below, and the study was mainly referred to "Hwangjenaegyoungju(黃帝內經注)" written by Wangbing(王氷), "Juhaesanghanron(注解傷寒論)", "Sanghanrye(傷寒例)" by Seongmugi(成無己), "Namyanghwalinseo(南陽活人書)", "Sanghanbaekmun(傷寒百問)" by Jugoeng(朱肱), "Sanghanbaekjeungga(傷寒百證歌)" by Heosukmi(許叔微), and "Injejikji(仁齊直指)" by Yangsayeong(楊士瀛). 'Gyeong(經)' quoted in "Sanghanpyeon(傷寒篇) in Uihakyimmun(醫學入門)" meant not only quoted from "Naegyoung(內經)", but "Sanghanron(傷寒論)" by Jangjunggyeong(張仲景). All the symptoms of Yukgyeong(六經) was sorted on the basis of "Juhaesanghanron(注解傷寒論)", and we can find the symptoms of Soyang(少陽) in the editing of Taeyangbyoung(太陽病), also symptoms of Taeeum(太陰) in Yangmyeongbyoung(陽明病). On the changing order of Yukgyeong(六經), "Jeungjuryujeunghwalinseo(增注類證活人書)" explained it through conflict of five stage, but "Uihakimmun(醫學入門)" interpreted it with proper and inverse condition of main stream of Yukgi(六氣).

${\ulcorner}$Zhujieshanghanlun(註解傷寒論)${\lrcorner}$ are som particular points as below ; first, set up the concepts of chuanjing(傅經), zaichuanjing(再傅經), and guojing(過經). Second, suggested the half exterior and half interior syndrome(半表半裏證) firstly. The third, understood origin literature by the distinguished way for syndrome in accordance with the Yin and Yang(陰陽). Forth, wangyang(亡陽) is described by two different syndromes. One is with perspiration. The other is yangxuzheng(양허증(陽虛證)) from injured yangqi(陽氣). Fifth, xialibiannongxue(下利便膿血) was distinguished by the generic characters of The Cold and Hot(熱${\cdot}$寒). The last, ${\ulcorner}$Shanghanlun${\lrcorner}$ (傷寒論) was described at the view of viscera & bowels's physiology and their pathology. And shaoyin(少陰) disease was aware of kidney case and Taiyin(太陰) disease was aware of spleen case. There are two different cases of bowel diseases. One is that xieqi(邪氣) goes in stomach of Yangming(陽明). The other is that xieqi(邪氣) follows channel and goes into bowel.

Inguinal hernia is the most frequent problem requiring surgery in children. Moreover, subsequent contralateral occurrence after repair of the symptomatic unilateral inguinal hernia(UIH) is not rare, This study is to evaluate the diagnostic value of inguinal ultrasonography (IUS) for potential bilateral inguinal hernia (BIH). A prospective study was performed for preschool children less than 6 years of age who were diagnosed as UIH from July 1999 to December 2000. We selected 58 cases with potential BIH, based on the past history, such as prematurity, ventriculo peritoneal shunt, family history of BIH. hernia on the left side (LIH), age below 2, female, and contralateral positive silk glove sign on the physical examination, Screening with IUS and bilateral surgical exploration were applied on these cases. Forty-seven cases were males (81.0%) and 11 cases were females (19.0%). Thirty four were infants. Symptomatic right inguinal hernia (RIH) were 28 (48.3%), and LIH were 30 cases (51.7%). Six cases had no evidence of contralateral patent process vaginalis (PPV) by IUS but showed contralateral PPV by operation. Two cases were suspicious to contralateral PPV under IUS, but operative findings were negative. Fifty cases showed contralateral PPV by IUS as well as operation. The detection rate of contralateral PPV under IUS was 86.2%. The preoperative IUS may reduce contralateral exploration.
