At early Cheong (淸) dynasty, in medical aspect by dependent on practical studying attitude that must found a theory only by an evidence, there had been a tendancy that hoped direct research of sages' mind-eye by escaping the theory of individual classes since Geum-Won (金-元) dynasty. Yoo Chang (喩昌), born in Man-Ryeok (萬曆) 12th year of Myung (明) dynasty (A.D.1583) and dead in Gang-Hee (康熙) 3rd year of Cheong (淸) dynasty (A.D.1664). The results were as follows after studying his practical idea of medicine. 1. Yoo Chang, by recognizing the ${\ll}$Sang-Han-Ro${\gg}$ has lost its true meaning after commented by Wang Hee (王熙), Lim Eog (林億), Seong Moo-I (成無巳), etc. according to Bang Yoo-Jip's (方有執) Chak-Gan-Jung-Jeong (錯簡重訂) theory, he diversified the protocal of ${\ll}$Sang-Han-Ro${\gg}$ 397 method and arranged under Six Meridian part. (六經) 2. The theory of Sam-Gang-Jeong-Rip (三綱鼎立) can be summerized Gye-Ji (桂枝) syndrome which is the case of Wind (風) has injured Wi (衛) stage, Ma-hwang (麻黃) syndrome which is the case of Cold (寒) has injured Yeong (榮) stage, Dae-Cheong-Ryong (大靑龍) syndrome which is the case both of Wind-Cold (風寒) has injured Yeong-Wi (榮衛) stage, and there has been Sam-Gang-Jeong-Rip theory by anterior medical practitioners already but the person who formally used its Sam-Gang-Jeong-Rip term is Yoo Chang. 3. Yoo Chang seized the On Byeng (溫病) by dividing three category and in Byon-Jeung-Si-Chi (辨證施治) he influenced to many aspect of establishment of later Byon-Jeung system On-Byong (溫病의 辨證體系) pertaining to Triple-Warmer by O-Dang (吳瑭) introducing Triple-Wanner Theory. (三焦理論) 4. At Chu-Jo-Ron (秋燥論) of ${\ll}$EUi-Moon-Beop-Ryo${\gg}$, while ${\ll}$Nae-Gyeong${\gg}$ describing if humidity injury Lung, then occur a disorder in it, Yoo Chang recognized that of au tuam when dryness injure Lung there occure a disorder is it so he insisted that at this case, must use Cheong-Joe-Goo-Pye method (淸操救肺法) withherbs, pertaing to Gam-Yoo-Ja-Yoon(甘柔滋潤性) property and he invented Cheong-Joe-Goo-Pye-Tang. (淸操救肺湯) 5. Yoo Chang', so called, Dae-Gi (大氣) indicates Yang-Gi (陽氣) of chest, he insisted that man's creation and every physiological activity depends on maintainence of Dae-Gi, and it integrate Yeong-Gi (榮氣), Wea-Gi (衛氣), Jong-Gi (宗氣), Jang-Boo-Ji-Gi (臟腑之氣), Gyeong-Rak-Ji-Gi. (經絡之氣) 6. Yoo Chang's expression about partical function and character of stomach, not only bolster its theory of historical physician's expression, that is stomach is. foundatness of postnatal period, but also it has corresponding aspect with modern medicine and clinic. 7. Yoo Chang emphasized "if one cure a disease, be must understood the character of disease first and use drugs later" (先議病 後用藥) phrase about of drug usage, and his theory of Geup-Rew-Man-Joo method (急流挽舟) and three therapy of Simple Ascite (單腹腸) are all unique opinion based upon this phrase mentioned above. 8. Yoo Chang's practical idea of medicine greatly influenced to Jang Ro (張璐), Hwang Won-A (黃元御), Oh Eui-Rak (吳儀洛), Joo Yang-Joon (周揚俊), etc. and theory of Sam-Gang-Jeng-Rip (三綱鼎立), Triple Warmer Theory of On Byong (溫疫의 三焦論治), Chu-Jo-Ron (秋燥論), Dae-Gi-Ron (大氣論) etc. became important object to student of Sang-Han (傷寒) and On-Byeng. (溫病) 9. Yoo Chang's Writings has more practical meaning than other physician's, especially, later the idea of Sang-Han (傷寒) and On-Byong (溫病) greatly contributed to development of Sang-Han theory and formation of On-Byong theory.

As home care in developing and becoming part of the health care delivery system in Korea, it is necessary to examine the use of nursing diagnoses and related nursing interventions with a view to increasing the standardization of nursing recording. This study was done to examine the nursing diagnosis and related nursing interventions used in home care. Data were collected using a chart review of the nursing notes written for the home care given to 38 patients who had pulmonary diseases or traumatic brain or spinal cord injuries and who had received home care as part of a demonstration home care project in a college of Nursing in Seoul. Early on in the project discussions as to format and use to nursing diagnosis was done and a tool was developed based on Gordon's eleven functional catergories with the addition of categories to cover family and environment. This tool was used in the data collection. Data included nursing diagnosis, etiologies and interventions. Real numbers and percentages were used in the analysis. The results show that the most frequently used diagnoses were in the category of physical function (75.6%), followed by the category of emotional and social function (21.8%). The least frequently used category was the one for family and environment (2.6%). The order of the frequency of recorded nursing interventions was the same, 82.3% for physical function, 16.2% of emotional and social function and 1.5% for family and environment. Under the category of physical functioning the most frequently used nursing diagnoses were related to mobility (62.2%), nutrition (23.6%) and elimination (11.9%). The frequencies of nursing interventions for these three diagnostic categories were 69.8%, 16.0% and 10.8% respectively. For emotional and social functioning, the most frequently used diagnoses were for cognition-perception (37.1%), self-perception (30.6%) and perception of health (23.7%). The ordering of the frequency of nursing interventions varied slightly. The most frequently used interventions were for the category of self-perception (31.7%) followed by cognition-perception (24.1%) and perception of health (22.9%). Looking at individual diagnoses, it was found that within the categroy of physical functioning, the most frequently used diagnosis was "impaired physical mobility" (29.5%) and this diagnosis involved 43.9% of the interventions. This was followed by "ineffective breathing pattern" (19.4%) with 17.7% of interventions, and "alteration in nutrition, less than body requirements" (11.2%) with 8.1% of the interventions. For the emotional social category, noncompliance was the most frequently used nursing diagnosis (18.2%) with 19.2% of the interventions. This was followed by "anxiety" (13.4%) with 13.6% of the interventions and by "knowledge deficit" (13.4%) but with only 5.5% of the interventions. The other diagnoses and interventions did not follow this pattern of frequency. Although there were a large number of diagnostic and intervention events, the number of actual diagnoses and interventions used were relatively small ranging from six interventions for "knowledge deficit" to 40 interventions for "imparied physical mobility". From this it can be concluded that the results of this study could be used as basic data for the development of standardized charts with respect to nursing diagnosis and interventions for clients with pulmonary disease and clients with traumatic brain or spinal cord injuries. Interventions that were direct care activities (1178) were much more frequent that education (430), and assessment and observation (148). There were also few diagnoses or interventions related to the family and the environment. This suggests two areas that need to be developed in home care and that need to be considered in the development of standardized records for use in home care.

This study examined existing theories of the characteristics of the abandoned tumulus site located at the east side of the Silla era Hwang Bok Sa (皇福寺) site and attempted an archaeological approach based on the derived facts, combining both the results of this study and those of a recently conducted excavation survey. The results of this investigation exhibited the following outcomes. First, the excavation survey revealed that the huge rounded stones discovered on the surface of a rice paddy field located at the east side of the Silla era Hwang Bok Sa were all protecting stones, processed on the front side in the form of a bow, designating a royal tomb. Most of these protecting stones had deviated from their original positions due to subsequent farming practices and some had been re-cycled for construction purposes as fences or foundations for structures built in the Silla era. Considering the prevailing belief in the concept of reincarnation, the bone rank system, and royal authority in the Silla era at that time, it would seem likely that the royal tombs were not intentionally destroyed. Therefore, it is speculated that the stones in this royal tomb were abandoned during construction of the tomb of the King at that time and then naturally re-cycled as building components used in construction sites in later years. Second, this study comparatively analyzed the scale and quality of the supporting stones at the royal tomb site in Guhwang-dong. The analysis results verified that those supporting stones were the same stones from the royal tomb used as supporting stones for statues symbolizing the twelve earthly branch spirits that were restored at the site of the tower at the royal tomb. This confirmed that the statues of the twelve earthly branches spirits sitting at the Hwang Bok Sa site were the protecting stones from a different royal tomb. Accordingly, the conclusion that has been generally accepted to date-that the protecting stones of the statues of twelve earthly branches spirits sitting at Hwang Bok Sa site were probably moved from the royal tomb site in Guhwang-dong-must inevitably be modified. Third, based on the structure of the protecting stones and type of the royal tomb, it is speculated that the individual buried in the royal tomb at Guhwang-dong is one of the kings who followed King Heungdeok and similar times of the buried person of the tomb that was considered as King Gyeongdeok, and who was before the buried person of the tomb that was considered as Kim Yu-sin. In addition, when considering the historical art patterns on the supporting stones of the statues that symbolize the twelve earthly branches spirits, which were moved to the site of the tower at the royal tomb, it is reasonable to believe that the person buried at the royal tomb at Guhwang-dong is likely one of the Kings of the late Silla era of the 9^th century.

The purpose of this study was to compare radiopacity and radiographic discriminability of various FRC-Posts. Six FRC-Posts were investigated ; 1) FRC Postec Plus (Ivoclar Vivadent AG, Schaan, Liechtenstein), 2) Snowlight (Carbotech, Lewis center, OH, USA), 3) Dentin Post (Komet Brasseler, Lamgo, Germany), 4) Rely-X Fiber Post (3M ESPE, St.paul, MN, USA), 5) D.T.-Light Post (BISCO, Schaumburg, IL,USA), 6) Luxapost (DMG, Hamburg, Germany) The radiographs of each post with a reference 1 mm / 2 mm aluminum step-wedge was taken using digital sensor. The optical density were calculated by gray value of $10{\times}10$ pixel and compared in mm Al equivalent at five points. Six maxillary incisors of similar radiopacity were used. Radiographs of posts in Mx. incisors of lingual side of dry mandible were taken. We showed radiographs and asked the questionnaire to 3 radiologists, 3 endodontists, 3 general practitioners. The questionnaire was comprised of choices of the highest, lowest radiopaque individual post and the choices of best discriminable post at apical, coronal area. The following results were obtained. 1. Each post system showed various radiopacity. 2. There was change of discriminability between each post and simulated specimens regardless of examiner. Although each post showed various radiopacity, the difference of radiopacity did not affect on discriminability.

Most of prior works on testing parallel programs have concentrated on how to guarantee the reproducibility by employing event traces exercised during executions of a program. Consequently, little work has been done to generate test cases, especially, from specifications produced from software development process. In this research work, we devise the techniques for deriving test cases automatically from the specifications written in Message Sequence Charts(MSCs) which are widely used in telecommunication areas and develop the testing environment for performing module testing of parallel programs with derived test cases. For deriving test cases from MSCs, we have to uncover the causality relations among events embedded implicitly in MSCs. For this, we devise the methods for adapting vector time stamping to MSCs, Then, valid event sequences, satisfying the causality relations, are generated and these are used as test cases. The generated test cases, written in TTCN, are translated into CHILL source codes, which interact with a target module to be tested and test the validity of behaviors of the module. Since the testing method developed in this research work extracts test cases from the MSC specifications produced front telecommunications software development process, it is not necessary to describe auxiliary specifications for testing. In audition adapting vector time stamping generates automatically the event sequences, the generated event sequences that are ones for whole system can be used for individual testing purpose.

Purpose : The purpose of the present study was to access the prevalence of orthostatic dysregulation(OD) and the frequency of each category for major and minor criteria among elementary school students using the OD questionnaire. Methods : We carried out inquiry by questionnaire as to the frequency of OD among two elementary schools with 725 students, 10 to 12 years of age, residing in Gwangju, Korea. The questionnaire was made according to criteria proposed by the Japan OD Study Group. Results : Of the 725 students(male 390; female 335) questioned, the OD was found in 338 students (53.5 percent). Prevalence of OD in males(59.2 percent) was significantly higher than in females(46.8 percent)(P<0.05). Palpitation with slight exercise(95.9 percent) was the most frequent major symptom. Headaches(85.8 percent) were the most frequent minor symptom among cases of OD. Conclusion : The prevalence of OD in elementary school students in this study(53.5 percent) was higher than in other studies. Contrary to studies from other countries, the male to female ratio was reversed. Because the diagnostic criteria seem to be dependent on subjective reporting of the symptoms, a newer diagnostic system based on more objective findings should be established.

The zinc-lead deposits at the Yeonhwa I mine were investigated in terms of ore-forming geologic setting, structural style of ore control, geometry of individual orebodies, zoning, paragenesis and chemical composition of skarn minerals, as well as metal grades and ratios of selected orebodies. The Yeonhwa I mine is characterized by a large swarm of chimney type massive orebodies with thin skarn envelopes, boldly developed through a thick sequence of Pungchon Limestone, the overlying Hwajeol Formation, and the underlying Myobong Slate of Cambrian age. Nearly 20 orebodies of similar shape, but of varying size are arranged in a V-shaped pattern with northwest and northeast trends, clearly indicating an outstanding ore control by a conjugate system of fractures with these trends. Important orebodies are the Wolam 1, 2, 3, and 5 orebodies in the west, and the Namsan 1, 2, 3. and 5 orebodies in the east, among others. The Wolam 1 orebody, which was observed from the -360 level through the -240, -120, and 0 levels to the surface outcrops (totaling a vertical height of about 500m), shows a vertical variation in skarn mineralogy, ranging from pyroxene-garnet zone on the lower levels. through pyroxene (without garnet) zone on the intermediate levels, and finally to rhodochrosite vein on the upper levels and surface. Microprobe analyses of pyroxene and garnet on a total of 14 mineral grains revealed that pyroxenes are manganoan salitic in most samples, with downward increase of Fe and Mn, whereas garnets are highly andraditic, containing fractions of subordinate grossular with downward decrease of Fe. This indicates a reverse relationship of Fe-contents between pyroxene and garnet with depth. Ore minerals are major sphalerite, subordinate galena, and minor chalcopyrite. Sulfide gangue minerals include major pyrrhotite, and minor pyrite and marcasite of later age. Two types of variational trends in metal grades and ratios with depth are present on the plots of assay data from the Wolam orebodies: one is a steady upward increase in Pb, Zn, and Pb:Zn ratios, with a terminal decline at the top of orebody: the other is an irregular or sinusoidal change. The former is characteristic of chimney-type orebodies, whereas the latter is of vein· shaped orebodies. The Pb grades show large variations among orebodies and from level to level, whereas the Zn grades are relatively constand or less variable.

A survey was carried out in Seoul Metropolitan area during December of 1993 and January of 1994. The objective of the survey was to provide a useful information for the development and improvement of recycling policies, regulations and systems in Korea. Of the 782 individuals contacted, 473 individuals completed and retured surveys, of which 437 were usable. The results were analyzed using a statistical package SAS(Statistical Analysis System). The results indicated that 86% of apartment area has recycling bins, while only 33% of individual house(detached dwelling) area has those. About half of the respondents felt that food waste is the major source of household waste. The most serious problem to recycle more household waste is to provide space to store recyclables at the source. The majority of Seoul Metropolitans(78.5%) are willing to participate in recycling programs, while 14.4% want to participate only when there are economic incentives or benefits. Respondents who want economic incentives appeared to be low income people. 66.1% of total respondents said that they do not use disposables. However, only 53,0% among respondents under 30 years old answered they do not use disposables. People who graduated from middle high school only and are under 30 years old have tendency to dispose of used milk cartons without rincing and drying, while those who are over 40 years old and graduated from university prefered to rinse and dry used milk cartons before disposal. Regarding disposal of newspapers, only 43.9% of the total respondents separated newspaper from other types of used paper. In the case of alumium cans, 22.5% of the total respondents answered that used aluminum cans are not recyclables. Much higher portion (30. 4%) of the respondents who graduated from middle high school only felt that aluminum cans have no value to recycle. The results indicated that education and information regarding recycling are highly desirable.

Damage produced by radiation elicits a complex response in mammalian cells, including growth rate changes and the induction of a variety of genes associated with growth control and apoptosis. At doses of 10,000 cGy or greater, the exposed individual was killed in a matter of minutes to a couple of days, with symptoms consistent with pathology of the central nervous system(CNS) including degenerative changes. The nature of the damage in irradiated cells underlies the unique hazards of ionizing radiation. Radiation injury to CNS is a rare event in clinical medicine, but it is catastrophic for the patient in whom it occurs. The incidence of cerebral necrosis has been reported as high as 16% for doses greater than 6,000 cGy. In this study, the effect of radiation on brain tissue was studied in vivo. Jun and p53 genes in the rat brain were induced by whole body irradiation of rat with 600Co in doses between 1 Gy and 100 Gy and analyzed for expression of jun and p53 genes at the postirradiation time up to 6 hours. Northern analyses were done using 1.8 Kb & 0.8 Kb-pGEM-2-JUN/Eco RI/Pst I fragments, 2.0 Kb-php53B/Bam HI fragment and ,1.1 Kb-pBluescript SK--ACTIN/Eco RI fragment as the digoxigenin or [${\alpha}^{32}P$] dCTPlabeled probes for Jun, p53 and ${\beta}$-actin genes, respectively. Jun gene seemed to be expressed near the threshold levels in 1 hour after irradiation of $^{60}$Co in dose less than 1 Gy and was expressed in maximum at 1 hour after irradiation of $^{60}$Co in dose of 30 Gy. Jun was expressed increasingly with time until 5 or 6 hours after irradiation of $^{60}$Co in doses of 1 Gy and 10 Gy. After irradiation of $^{60}$Co in dose between 20 Gr and 100 Gy, the expression of Jun was however increased to peak in 2 hours and decreased thereafter. p53 gene in this study also seemed to be expressed near the threshold levels in 1 hour after irradiation of $^{60}$Co in dose less than 1 Gy and was expressed in maximum at 6 hours after irradiation of $^{60}$Co in dose of 1 Gy, p53 was expressed increasingly with time until 5 or 6 hours after irradiation of $^{60}$Co in dose between 1 Gy and 40 Gy. After irradiation of $^{60}$Co in doses of 50 Gy and 100 Gy, the expression of p53 was however increased to peak in 2 hours and decreased thereafter. The expression of Jun and p53 genes was not correlative in the brain tissue from rats. It seemed to be very important for the establishment of the optimum conditions for the animal studies relevant to the responses of genes inducible on DNA damage to ionizing radiation in mammalian cells. But there are many limitations to the animal studies such as the ununiform patterns of gene expression from the tissue because of its complex compositions. It is necessary to overcome the limitations for development of in situ Northern analysis.

There have been raised other environmental issues related to remediated soils piled up in numerous carry-out processing facilities because a considerable quantity of them have been produced every year, but most of them have not been relevantly reused or recycled. Thus, this article reports the trend of researches on the development of techniques to restore the quality of remediated soils to activate their reuse and recycling. Firstly, the tendency of change in soil properties through remediation processes was looked over, and then the degradation of soil quality was characterized according to the type of remediation processes. Besides, the direction of policy to promote the reuse and recycling of remediated soils was introduced, and finally, the future works needed were suggested. This article was prepared based on the results of the survey of domestic and foreign literature. A number of literature were reviewed to scrutinize the change of soil properties due to remediation processes and diverse techniques for the amendment and restoration of remediated soils. Furthermore, the policies related to the reuse and recycling of remediated soils were arranged with the reference of the first and second versions of the Soil Conservation Master Plan of Korea. The literature survey focused on three kinds of remediation technologies, such as land farming, soil washing, and thermal desorption, which were most frequently used so far in Korea. The results indicate that the tendency of change in soil properties was significantly different depending on the type of remediation processes applied, and the degradation characteristics of soil quality were also totally different between them. The soil amendment and restoration can be categorized as three techniques depending on the type of substances used, such as inorganic, organic, and biological ones. Diverse individual materials have been used, and the soil properties improved or enhanced were dependent on the type of specific materials utilized. However, few studies on the restoration of soil qualities degraded during the remediation processes have not been carried out so far. The second Soil Conservation Master Plan states the quality certification and target management system of remediated soils, and it is expected that their reuse and recycling will be facilitated hereafter. With the consideration of the type of remediation processes implemented and public utility, the restoration technologies of remediated soils should be developed for the vitalization of their reuse and recycling. Besides, practical and specific measures should be taken to support the policy specified in the second Soil Conservation Master Plan and to promote reuse/recycling of remediated soils.
