  • This study was designed to identify the general health conditions and high risk factors of the male & female environmental workers. Thereby. the results of this study were to provide useful data as a contribution to knowledge for health protection and promotion. The data used for this study were environmental workers' physical examination cards; the male environmental workers were 52 persons. and the female environmental workers 52 persons. The data were analyzed by descriptive statistics, t-test, Pearson correlation, and distinction analysis, using the SPSS program. The results of this study can be summarized as follows; 1. Thers was a significant statistical difference between the two groups as to height. eyesight. serum GPT, hematocrit. The variables having little difference between two groups were weight. systolic blood pressure. total cholesterol. creatinine. 2. The rate of revealed in significant health examination was extra-health discrimination rate $28.8\%$, significant result of illness rate $12.5\%$. injury-inflicting rate $7\%$. second-time urine test $5.7\%$. antigen positive 3.8%. hearing impairment $2.8\%$, urine protein positive $1.9\%$. and urine sugar positive $1.9%$. 3. The workers diagnosed as extra-health discrimination were 30 persons or $28.8\%$. There was a difference between two groups on the prevalence. In the male environmental workers. ten times live problems and six times pulmonary tuberculosis and three times circulatory problems were revealed the higher than thoes of the female environmental workers. 4. In the male environmental workers, the relationship between age and systolic blood pressure revealed a significant correlation (r=0.22. p<0.05). In the female environmental workers. there was a negative correlation between age and weight (r= 0.25, p<0.05). the relationship between age and total cholesterol correlated positively (r=0.30, p<'0.05). 5. In the male environmental workers, there was a negative correlation between working career and creatinine(r=-0. 22, p<0.05) In the female environmental workers, there was a positive correlation between working career and total cholesterol (r= 0.58, p<0.01). 6. There were significant differences on working career and creatinine accdording to the male and female environmental workers who had any problems through x-ray inspection. 7. There were significant differences on height. eyesight. serum GPT according to the male and female environmental workers who were diagnosed as extra-health discrimination. 8. The female environmental workers who were diagnosed as 'care' were positively correlated with weight (r= 0.26. p<0.05)' and systolic blood pressure (r= 0.30. p<0. 05). on the other hand. the left and right eyesight correlated nagatively(r=-0.15. r=-0.33. p<0.01). 9. The most influential variables on the male and female environmental workers' health condition were working career, height. and weight. And these three variables could help determine the two groups at the level of 81. 8 percentage.

  • 트럭믹서 및 배쳐 플랜트 세척으로 발생되는 회수수를 안정화시켜 재이용하는 것은 콘크리트의 품질 불안정을 해소하고 강도 향상의 효과를 기대할 수 있기 때문에 이의 활용방안에 대한 적극적인 검토가 요구된다. 본 연구에서는 우리나라의 레미콘 생산 조건에서 사용 가능한 안정화제의 종류를 도출하고자 이를 사용한 회수수 중의 고형분 성상에 대하여 실험?고찰하였다. 실험결과, 회수수 전용 안정화제인 옥시칼본산계 지연제의 고형분량 감소가 상대적으로 우세하였다. 다만, 잉여 반응량에 의해 시멘트 페이스트의 응결지연이 관찰되었으나 레미콘 적용상 저해되는 수준은 아니었다. 안정화제를 혼입한 회수수를 방치함에 따른 영향에서는 초기의 응결지연 효과가 7${\~}$8일 정도에서 상수도수만을 사용한 수준으로 회복됨을 알 수 있었으며, 2${\~}$3일 정도에 안정화 회수수를 사용하는 것이 효과적임을 확인할 수 있었다. 한편, 국내산 당류계 초지연제 역시 유사한 효과를 보여 적용성이 높은 것으로 파악되었다. 시판되는 회수수 안정화제는 수입에 의존하고 있으므로 사회비용의 절감을 위해 안정화제의 국산화가 시급하며 가능한 안정화제의 다각적인 사용성 검토가 긴요하다 할 것이다.

  • Objectives : With recent improvements in neuroimaging and the development of third and fourth-generation radiosurgical dose-planning soft ware, came a renewed interest in using radiosurgery for the treatment of movement disorders. Radiosurgery involves no opening of the cranium and no incisions, eliminating both the risk of hemorrhage from passing an electrode to the depths of meningitis from operative infection. It is for these reasons stereotactic radiosurgical treatment of movement disorders has value in a small subgroup of patients. The authors report four cases of Parkinson's disease and one case of dystonia that were treated by Gamma knife. Methods : Radiosurgical nucleus ventralis intermedius thalamotomy using the gamma knife unit was performed to make lesion in two Parkinson's disease patients. A radiation dose of 120Gy was delivered to nucleus using a single 4-mm collimator plug pattern following classic anatomical landmarks. Patients were followed for a median of 10.5 months(range 9-12 months). An independent neurological evaluation of tremor, based on the change in the United Parkinson's Disease Rating Scale tremor score(UPDRS), was correlated with a subjective evaluation. Gamma knife ventrolateral(V.O.P) thalamotomy was performed in one case of dystonia. A central dose of 150Gy was delivered and the patient was followed for 18 months. Gamma knife globus pallidus interna pallidotomy was performed in two Parkinson's disease patients. A radiation dose of 130Gy(range 120-140Gy) was delivered. Patients were followed for a median of 13 months(range 9-14 months). Result : Ventrolateral thalamotomy in dystonia produced regained left hand usage in order to be able to use the telephone. Ventralis intermedius thalamotomy produced an excellent improvement of the tremor in one case, mild improvement of the tremor in the other case of Parkinson's disease. A globus pallidus internalis(GPi) pallidotomy produced improvement of rigidity and dyskinesia : one other showed no change. There were no neurological complications. Conclusion : Gamma Knife thalamotomy considered a safe and effective technique for the treatment of tremor in Parkinson's disease. Although the results from Longer follow-up is not available yet, the short-term results seem to be encouraging.

  • It has been more than ten years since Dukun mine was abandoned. Tailings of waste deposits and slime dumps in the abandoned Dukum mine have been left to be deserted for fifty years. The results of fifty years of neglecting are nothing short of major environmental problems. Slime dumps have been exposed to air and water in the mine over ten years and then soil profile has been formed well. Soil in the upper layer (A horizon) is the light gray color due to the leaching of cations. Soil in the lower layer (A2 horizon, 0.2∼0.3m)is tinted with reddish brown and yellowish brown color due to the development of iron oxides and iron hydroxides. Soil in the lower part of B horizon of (1.0∼3.0m) with the growth of copper and zinc oxides exposes to the bluish green, light blue, and dark gray. Ranging from 3m to 8m in depth, 85 samples were taken from 22 sampling sites with 50m intervals located on the slime dump area with hand auger and trench (open cut). As tailings was distributed, heavy metal elements extracted by the process of surface water and ground water move and disperse in to the hydrosphere. Waste dumps were distributed in and around the mine and water draining from those dumps be a potential source of contamination. Soils, thus, can be dispersed into downslope and downstream through wind and water by clastic movement. These materials may be deposited in another horizon if the water is withdrawn, or if the materials are precipitated as a result of differences in pH, or other conditions in deeper horizons. These were primarily associated with acid mine drainage. The characteristics and rate of release of acid mine drainage are influenced by various chemical and biological reactions at the source of acid generations. Prolonged extration of heavy metal elements has a detrimental effect on the agricultural land and residental area. Twenty soil samples were collected from the agricultural land in the area (0∼30 cm). Seventeen samples were also taken from the sediment in the stream running alongside the dumps. The dispersion patterns of heavy metal elements are as follows: The content of As ranged 2∼6 ppm in a horizon, 20∼125 ppm in B horizon with large amount of clay mineral is concentrated and the content of Cd ranged 1∼2 ppm in A horizon, 4∼22 ppm in B horizon. Like Cd, the content of As, Cu, Zn, Pb in B horizon is higher than that in A horizon (approximately 5∼100 times). When soil formation proceeds in stages, it is necessary to investicate the B horizon with the concentration of heavy metal and preventive measures will have to established.

  • This study was attempted to investigate the pneumatic separation on separating unit of a combine harvester. The aerodynamic characteristics of threshed materials were analyzed by experiments. The air velocity distribution within the separation chamber was measured for various speeds of the winnower and suction fans to find out the operational and design conditions of the separating unit which would serve for reducing the grain loss from chaff outlet. The results of study arc summarized as follows: 1. Based on the separation curve of threshed materials analyzed, it was shown that three different kind. of materials-kernels, straw chaff, and leaf chaff were as a whole able to be separated pneumatically, regardless of varieties. However, a small amount of the separation grain loss may be expected to occur if the complete separation between kernels and straw chaff would be undertaken because some portion of their separation curve were overlapping. 2. The analysis of air velocity distribution showed that the separation chamber may be divided into two regions, the discharging and separating. The air velocity of the discharging region was 5-15 m/s and that of the separating region 2-5 m/s. 3. The air movement of the separation chamber may be a turbulence flow, being its speed became greater as it moves from the left to the right section of the separation chamber. The equi-speed line. of air flow had a steep gradient in between the discharging and the separation regions. The air velocity in the discharging region was much higher than the terminal velocity of kernels, because of which those kernels appearing in the region could be possibly exhausted as the grain loss from the chaff outlet. 4. The motion trajectory of threshed material in the separating region was dominantly affected by the winnower fan, on the other hand, its motion in the discharging region was affected by suction fan. 5. The grain loss from the chaff outlet was affected greatly by the winnower fan and the trace of kernel movement. It was observed that the optimum working speed to give minimum grain loss from chaff outlet for the combine tested should be maintained at 950~1,150 rpm for the winnower fan and 1,850 rpm for the suction fan. 6. It was shown that a large portion of grain loss from chaff outlet may occur when the kernels may bump against a portion of separation chamber wall and those kernels thus scattered into the discharging region were sucked by the suction fan. It was accordingly recommended that a new design of the wall of separation chamber so as to bump down kernels may be necessary to reduce grain loss from the chaff outlet.

  • As it is known, during the Second World War Greece has fought on the side of the allies and the end of the war found the country on the winners' side. However, the struggle for authority right after 1945 was merciless and extremely difficult, as well as dangerous for the course of the country to the future. The political powers were divided between the legal authorities that were represented by the king and formed the exiled government on the one hand and the part of the resistance teams and the rebels of the left that had a soviet friendly direction on the other. Thus, the start of a civil war was just a matter of time. It fin ally started in 1947 and lasted for more than two years. The consequences were disastrous for the country's economy and decisive for the future course of Greece. The national army prevailed with the help of, mostly, the English. Royal parliamentary democracy was established with a clear political turn to the west, as a completion and adaptation of the Agreement of the Great Powers at Yalta. Art had a 'similar' route. Dipolar, contradictory: conservative choices on the one side, and a will for pioneering inspiration and perspective on the other side. The 'dominate' trend was first evident in sculpture and mainly in the public monuments. Their construction aimed mostly at the public propaganda and at the promotion of the sovereign ideology. On the one side we have the public sculptures composed of faces of contemporary heroes or leading figures of the civic war and the national resistance. On the other side we have monumental statues mainly that appeal to a 'public' outside of the country's borders and mostly of the north borders, where there are countries with a communistic regime, like Bulgaria, Serbia and Albania. Their subject is derived from the heroic events of the Balkan Wars (1912-1913) and ancient historical figures like Alexander the Great as the Greek army leader, his father, Philippos II and Aristotle, who was of a north-Greek origin. The political message is twofold: on the one side the 'inner enemy' the communists that were defeated and the promotion of the new liberal social system and on the other side the north neighbours, which not only represent the East Block, but they also conspire the history and the culture of the Greeks. This is the way how the 'Cold War' was resulted in a full and totalitarian expression in art.

  • Subject : The Association between Extraordinary Organs(奇恒之腑) and Eight Extra Meridians(奇經 八脈). Objectives : This study research some special aspects of Extraordinary Organs and Eight Extra Meridians which differentiated from ordinary Organs and Meridians, and the association between Extraordinary Organs and Eight Extra Meridians. Methods : First, researched classification standard and physiological characteristics of Extraordinary Organs through studying various chapters of HuangdiNeijing. Second, researched The Association between Extraordinary Organs and Eight Extra Meridians through studying on the origin of Eight Extra Meridians in HuangdiNeijing. Third, from accompanying researching the subject of Cheon-gye(天癸) and human body shape, draw synthetic hypothesis on the relationship among ordinary Meridians and Organs, muscles and skins of body shape, Extraordinary Organs and Eight Extra Meridians. Results & Conclusions : The following conclusions could be drawn. 1. Extraordinary Organs afford background for shaping human body. This is same as the properties of the earth which afford background for shaping all creations. The physiological characteristics of Extraordinary Organs is intermediation and regulation between Ki(氣) of Five Viscera & six Bowels and shape of muscles & skins in human body. 2. The origin of Eight Extra Meridians could be found in HuangdiNeijing. The collateral Meridians of the Uterus and Epiglottis Meridian are specifically formulated to supplying for the Uterus or Epiglottis. From this we can draw The Association between Extraordinary Organs and Eight Extra Meridians, that is Eight Extra Meridians are specifically formulated to supplying for Extraordinary Organs. 3. The Cheon-gye(天癸) is doing significant function in Eight Extra Meridians supplying for Extraordinary Organs. Cheon-gye concerned to growth, secondary sexual characters, generative function, aging process. Theses are all concerned with the changing of human body shape. Cheon-gye urge to change the body shape with following the human life cycle. 4. Human body has vertical symmetry because preserve its shape from the gravitational force. Eight Extra Meridians place at the middle or flank axis of human body, thus do physiological function that assistant human body have vertical symmetry shape. The purpose of shaping vertical symmetry is securing space what the inner Twelve Regular Meridians and Five Viscera & six Bowels create there own physical changes. On the other hand the inner changes need deviation between left and right because of mobility and circulation of force. But human body change the shape in the process of growth, reproduction, aging. Eight Extra Meridians play role at time of these processing, thus they deeply concerned to human's life cycle and reproduction. 5. Eight Extra Meridians and Extraordinary Organs were named 'Extra' because of some special aspects which differentiated from ordinary Meridians and Organs. All they play role to have vertical symmetry shape of human body and maintain the shape, thus they deeply concerned to the change of human life cycle. These shaping maintaining and the change of human life cycle are very special aspects of human body. So they needed to differently cognize separate to the ordinary changes of Five Viscera & six Bowels and Twelve Meridians at inner space.

  • When feeling the pulse, healthy man' pulse is the criterion for diagnosis whether you are a sick person. Healthy man is defined as one who is harmonious and not sick in sympathy with natural order. Among the factors for being Healthy man, breathing and pulsation, Chon-gu(寸口) and Inyeong(人迎) are most closely connected with the representative methods of feeling the pulse which are used currently. According to "Hwangjenaegyeong(黃帝內經)" on breathing and pulsation, the pulse beats twice per a breathing-in and a breathing-out each. And for a specific breathing, it beats 5 times including the remnant with a big breath. That the pulse beats twice means that it beats not only twice, but also regularly and repeatedly. The remnant is related to the meaning on a leap month, 5-time beating during a breath is connected with the contents of Osipyeong(五十營). A human is not always in stable and sticks to balance continuously with changes under the circumstances. So when it comes to a criterion how to measure the pulsation frequency, breathing is much more reasonable than pulsation and breathing calculated for a minute. According to "Hwangjenaegyeong(黃帝內經)", Healthy man is the person of whose Chon-gu and Inyeong are in order and much the same in response to each other. Although there is a minor difference in the meaning of term between Chon-gu and Gigu(氣口), Maekgu(脈口) in originally, it is used as almost same meaning when Chon-gu is used in opposition to Inyeong. Afterwards, depending on medical men, around neck or Chon-gu of the left hand are measured for Inyeong. However, Inyeong described in "Naegyeong(內經)" is Jokyangmyeong(足陽明) and it means the Hyeol(穴) around neck where the pulse beats, it looks like about the carotid area. Chon-gu is fall under Eum(陰) and Inyeong(人迎) is fall under Yang(陽). Therefore Chon-gu is continuous with eumgyeong(陰經) and Inyeong is continuous with yanggyeong(陽經). In addition, the pulse and the four seasons meet each other and Inyeong is a little stronger in spring summer and Chongu is a little stronger in fall winter.

  • 최근, 유명 연예인과 인사들의 우리나라 위인에 대한 망언과 실언이 방송에 나감으로써 국민들에게 질타를 받는 안 좋은 이슈를 일으켰다. 반면에, 유명 예능 프로그램에서 특집 편성한 일련의 방송으로 인해 국민들의 역사의식이 높아지고 있다. 이렇게 국민들이 우리나라 역사에 대한 생각이 깊어졌을 때 반드시 짚고 넘어가야 할 점은 바로 역사의 사실성이다. 매체에는 '몰입'이라는 강력한 힘이 존재하기 때문에 수용자 즉, 플레이어가 그 게임에 흥미만 갖게 하는 것이 중요하다. 따라서 역사 사실을 바탕으로 제작된 게임들이 플레이어의 흥미 유발과 관심을 끌기 위해 또는 게임과 캐릭터의 특징을 만들기 위해 역사적 사실과 맞지 않게 제작하는 상황이 발생한다. 그래서 본 연구자는 플레이어들이 올바른 역사의식을 가질 수 있도록 역사 사실을 바탕으로 제작된 'HQ team'사에서 개발한 '천년의 신화'라는 게임을 선정해서 게임 속에 등장하는 '광개토대왕', '근초고왕', '무열왕'의 디자인과 역사적 사실을 비교 분석하고자 한다. 그 결과 역사적인 사실과 게임 속 캐릭터의 디자인이 일치하지 않는 것으로 나타났다.

  • The occupational health problems are the major issue in the modern industrial society. Especially the small scale industries have many hazardous factors and not any occupational health programs in itself. Fortunately. the government-funded subsidiary program was developed and carried out in the past six years in our country. The purposes of this study were to find out the actual condition of the occupational health personnel's accomplishments for the government-funded subsidiary program for small scale industries and to provide basic data for setting up more developed subsidiary occupational health program. Data were collected through 6 kinds of service records review. These service records were written by 3 occupational health personnels were attached to the one subject center of KIHA. were undertaken during March to December, 1997. at 95 small scale industries which were applied the government-funded subsidiary occupational health program. Results were as follows 1. Concerning 95 small scale industries showed characteristics of a typical small scale industry. 2. A doctor visited in industries total 190 times per year, average 19 industries per month, twice per year and industry. A hygienist visited in industries total 378 times per year, average 38 industries per month, four times per year and industry. A nurse visited in industries total 477 times per year. average 47 industries per month, 5 times per year and industry. 3. 3 occupational health personnels accomplished total 3,869 items. A doctor accomplished total 539 items per year, each time 3 items In an industry. A hygienist accomplished total 1.581 items per year, each time 4 items in an industry. A nurse accomplished total 1.749 items per year, each time 4 items in an industry. 4. The major contents of doctor's accomplishment were 'health consultation for suspicious worker with general & occupational disease', 'a check of the workplace & special health education', 'guidance of special medical examination in the second half of year', etc. The major contents of hygienist's accomplishment were 'pretest & guidance of planning for evaluation of working environment'. 'evaluation for ventilating facilities & suporting self inspection', 'guidance of MSDS recording & chemicals management', etc. The major contents of nurse's accamplishment were 'health counseling of general & special medical examination results'. 'health education of preventing occupational disease & health disorder'. 'guidance of subsidiary program planning', 'selecting & guidance of health monitor', etc. It was concluded that the occupaional health personnels implemented the subsidiary program according to the order of health management guide. The current health management guide of subsidiary occupational health program in which the fixed contents, visiting number & periods is not desirable. That guide is left the characteristics of small scale industries out of consideration. It is suggested that occupational health management guide should be developed according to the general & environmental characteristics of each small scale industry, and on the other hand, the more specific guide for each occupational health personnel should be developed.
