  • 본 실험에서는 매리골드 추출물의 첨가 수준별 급여가 산란계에서 난 생산성, 난질 및 계란의 보존성 및 난황 내 루테인 함량에 미치는 영향을 조사하였다. 55주령의 Hy-Line 갈색계 189수를 공시하여 모두 7개 처리구에 3반복 반복당 9수씩 완전임의 배치하였으며, 총 6주간 사양 실험을 실시하였다. 옥수수와 대두박 위주의 시판 사료를 급여하는 대조구와 매리골드 추출물을 각각 0.1%, 0.3%, 0.5%, 1.0%, 1.5%, 2.0% 수준으로 첨가한 실험구로 구분하였다. 실험 기간 중의 사료 섭취량, 산란율, 난중 및 일산란량을 조사하였고, 주별로 수집한 계란의 난질 및 난각질을 평가하였으며, 실험 마지막 주에 생산된 계란은 시간 경과별 Haugh unit의 변화와 난황 내 MDA 농도를 측정함으로써 계란의 보존성 평가를 위한 시료로 사용하였다. 사료 섭취량에 있어 각 처리구간 큰 차이가 없었고, 이는 매리골드 추출물이 산란계의 기호성에 미치는 영향이 없었음을 보여준다. 산란율에서는 처리간에 유의차가 인정되는 큰 차이가 없었지만, 매리골드 추출물을 첨가한 모든 처리구에서 대조구보다 높은 경향이 관찰되었다. 난중은 대조구에 비해 매리골드 추출물을 첨가한 처리구에서 증가하는 경향이 있었지만 유의차는 없었다. 일산란량에서는 매리골드 추출물을 0.5% 첨가한 처리구를 제외한 모든 처리구가 대조구에 비해 상대적으로 높았지만, 처리구간 유의차는 없었다. 난질 및 난각질에 미치는 영향 중 난각 강도와 난각 두께에서는 처리구간 큰 차이가 없었다. 난황색은 매리골드 첨가수준에 따라 유의차 있게 개선되는 것을 확인할 수 있었다(p<0.05). Haugh unit에서는 매리골드 추출물을 0.1%, 0.3%, 0.5% 첨가한 처리구가 대조구에 비해 유의차 있는 높은 수치를 보여 주었다(p<0.05). 매리골드 추출물의 수준별 급여가 시간 경과별 Haugh unit의 변화와 난황 내 MDA 농도에 미치는 영향에서, 보존 7일째에 조사한 Haugh unit에서는 유의차가 없었지만 모든 처리구가 대조구에 비해 수치가 높았고, 14일째에 조사한 Haugh unit에서는 대조구에 비해 매리골드 추출물을 0.3%, 1.0% 첨가한 처리구의 값이 유의차 있게 개선되는 경향을 보여주었다(p<0.05). 난황 MDA 농도는 대조구에 비해 매리골드 추출물을 0.5% 이상 첨가한 모든 실험구에서 유의하게 감소하는 결과가 관찰되었다(p<0.05). 난황 내 루테인 함량은 매리골드 추출물의 0.5% 이상 첨가한 처리구에서 매리골드 추출물의 첨가량에 비례하여 유의하게 증가하였다(p<0.05). 이는 매리골드 추출물에 함유되어 있는 루테인 성분이 계란 내에 순조롭게 이행되었다는 것을 뜻하며, 계란 무게를 60 g으로 환산하면, 매리골드 추출물을 2% 급여하였을 때 난황 내 lutein 함량이 최대 1.71 mg/60 g까지 증가함을 알 수 있다. 산란계 사료에 있어 매리골드 추출물의 다량 첨가는 산란율을 비롯한 생산성에 부정적인 영향을 미치지 않았고, 난황색 및 신선도를 포함한 난질 개선 효과가 있었으며, 계란의 유통 및 저장 기간 동안의 신선도 유지와 계란 내 지질 산화를 억제하는 효과가 있으며, 매리골드 추출물의 첨가 수준에 따라 난황 내 루테인 함량이 증가함을 확인할 수 있었다.

  • A descriptive correlation study was done to provide a basic data for comprehensive nursing care by analyzing the relationship between spiritual wellbeing, hope and perceived health status of the rural elderly. 130 respondents who lived at their homes and nursing homes for elders in D county. Kyungbuk province were selected and their age was over 60 years old. Paloutzian and Ellison(1982)'s spiritual wellbeing scale. Nowotny(l989)'s hope scale and Northern Illinois University's health self rating scale was used. From September 2nd to September 30th, 2002, ready made questionnaires were handed out by researcher and two well trained nurse research assistants. to those who can fill it out and for those who cannot fill out the questionnaires alone, the researcher and assistants read it and finished by interview. This study used Pearson's correlation coefficient for the hypothetic test and the average point and standard deviation of spiritual wellbeing, hope, and perceived health status were checked. To find out the difference between spiritual wellbeing, hope, and perceived health status by general characteristics ANOVA and Tukey test were used. The results are as follows : 1. The mean score for spiritual wellbeing of the rural elders was $49.94(\pm5.62)$ in a possible range of 20-80. The mean score of religious wellbeing was $25.20(\pm3.91)$ and that of existential wellbeing was $24.74(\pm2.83)$ in a possible range of 10-40. The average point of religious wellbeing was $2.52(\pm0.39)$ points and existential wellbeing was $2.47(\pm0.28)$ points to 4 point full marks. 2. The mean score for hope was $67.68(\pm10.92)$ in a possible range of 29-116. The average point of hope was $2.33(\pm0.38)$ points to 4 point full marks. 3. The mean score for perceived health status was $9.95(\pm2.66)$ in a possible range of 4-14. The average point of perceived health status was $2.15(\pm0.72)$ point to 4 point full marks. 4. In testing the hypothesis concerning the relationship between spiritual wellbeing and hope, there was a statistically positive correlation(r=0.621. p=0.000). 5. In testing the hypothesis concerning the relationship between hope and perceived health status, there was a statistically positive correlation(r=0.305, p=0.000). 6. There were significant differences in spiritual wellbeing according to age(F=5.60, p=0.000), religion(F=11.61. p=0.000), family status(F=2.86, p=0.040) and average monthly pocket money(F=4.32, p=0.015). 7. There were significant differences in hope according to age(F=16.49, p=0.000), religion (F=3.56, p=0.009), educational level(F=8.94, p=0.000), present occupation(t=-3.13, p=0.002), family status(F=5.90, p=0.001) and average monthly pocket money(F=3.41. p=0.036). 8. There were significant differences in perceived health status according to present occupation(t=-2.16, p=0.033) average monthly pocket money(F=4.11, p=0.019). From the above results it can be concluded that: There was a positive correlation between spiritual wellbeing and hope, hope and perceived health status. There was no positive correlation between spiritual wellbeing and perceived health status. For futher study, adequate spiritual wellbeing scale and hope scale for rural elders should be developed and, age and religion factors has to be reconsidered. When the nurse implicate the nursing intervention which can be promote the spiritual wellbeing and hope, rural elder's spiritual wellbeing and hope can be improved and at the same time, their perceived health status also can be improved.

  • 이 연구는 전라북도를 사례로 부모-자녀 세대에 걸쳐 진행되는 단계적 이동이 비수도권 중소도시 인구 성장에 미치는 영향을 탐색하는 것이다. 이를 위해 부모 세대를 베이비 부머, 자녀 세대는 에코 부머로 설정하였고, 거시자료를 이용하여 이들의 출생, 분포 변화와 선별적 이동과정을 추적하였다. 그리고 단계적 이동을 분석하기 위해 전라북도 시부, 군부 및 타 시도를 각각 출발지와 도착지로 설정하였다. 연구의 주요 결과는 다음과 같다. 첫째, 베이비 부머 세대는 전라북도 시부보다 군부에서 출생아수가 약 7배 이상 많았던 것으로 추정된다. 둘째, 부모 세대가 성장하여 선별적 이동을 진행할 때, 전라북도 시부와 군부 모두에서 타 시도로, 특히 수도권과 대도시로 이출이 탁월하게 나타났다. 하지만 전라북도 군부 출생자 상당수는 시부로도 이동하였고, 그 이동량은 전라북도 시부에서 타 시도로 이출한 양을 채워주는 수준이었다. 셋째, 자녀 세대에서는 전라북도 군부보다 시부에서의 출생아수가 더 많은데, 이것은 부모 세대가 농촌에서 도시로 단계적 이동을 했던 것에 기인한다. 넷째, 자녀 세대의 20대 연령 선별적 이동에서도 부모 세대와 유사하게 수도권과 대도시 등으로 이출이 압도적인 비율을 차지하였다. 그러나 전라북도 군부에서 시부로 이입되는 이동량이 부모 세대에 비해 현저하게 줄어들었고, 결과적으로 전라북도 도시들에서 음(-)의 순이동자 수가 해마다 누적되고 있다. 마지막으로 단계적 이동은 인구의 사회적 성장요인이자 동시에 이동자 생애경로의 결혼, 출산, 양육 등과 결부되어 자연적 성장요인에도 영향을 주었다. 따라서 부모-자녀 세대에 걸쳐 진행되는 단계적 이동은 비수도권 중소도시 인구의 증가와 감소를 결정짓는 주요한 요인이라고 할 수 있을 것이다.

  • 미국에서 일반항공산업의 보호를 위해 입안된 GARA는 일반항공의 제조업자를 지나치게 보호한다는 비판에서 지속적으로 위헌성이 제기됨에도 불구하고 현재까지 적용되고 있는 법률이다. 일반항공 사고에 관한 소송에서 우리나라 국민이 원고나 피고가 되었을 때 이 법이 직접적으로 적용될 수 있다는 역외적용의 측면에서 이 법은 우리에게도 큰 의의가 있다. 또한 GARA는 일반항 공기 및 그 부품에 관한 특별법이지만, 제소기간을 18년으로 확정하면서 제소 기간의 의미, 기산점, 적용제외 등을 상세히 규정하고 있어서 일반 제조물책임상 제소기간 규정과의 좋은 비교가 된다. 특히 제소기간 규정과 관련하여 우리 제조물책임법이 일률적으로 10년이라는 제소기간을 설정하면서 이에 관한 구체적인 적용과 관련한 규정을 전혀 두고 있지 않아서 문제이다. 제조물의 개별적 특성을 고려하지 않은 일반규정으로 인하여 일반항공에서 특별히 18년이라는 제소기간을 규정하고 있는 미국보다 한국의 제조물책임법이 더 짧은 제소기간을 운영하여 한국의 일반법이 미국의 특별법 보다 제조업자를 더욱 두텁게 보호하는 결과가 되고 있다. 이러한 문제점의 인식하에 GARA의 제소기간 규정으로부터 우리의 제조물책임법의 향후 개정방향을 다음과 같이 짚어 볼 수 있다. 첫째, 제조물책임법상 제소기간을 일괄적으로 정하는 것 보다는 여러 가지 다양한 제조물을 유형화하여 개별적 제소기간 규정을 두는 것을 고려해 볼 수 있다. 둘째, 실제 소송에서 소모적인 논쟁을 방지하기 위하여 제조물 공급일의 의미를 명확히 규정할 필요가 있다. 셋째, 제소기간 규정을 일률적으로 적용하는 것이 합리적이지 못한 경우를 대비하여 제척기간으로 해석되는 우리의 제소기간 규정이 적용되지 않을 수 있는 예외조항을 둘 필요가 있다. 비교법적인 관점에서 제조물책임상 제조업자와 피해자인 소비자 간의 이익 균형을 맞출 수 있는 합리적인 제소기간 규정의 설정이 모색되어야 하겠다.

  • The purpose of this study was to examine factors influencing the meaning of life for middle-aged women. The subjects for the study were 190 middle-aged women who live in Busan. Data were collected from May 25 to June 20, 1999. The instruments for this study were as follows : the meaning of life scale developed by Jung D. R(1978) ; the self-esteem scale developed by Ro, E. Y, Kwon, J. H.(1997) ; the volunteer activity scale developed by Park G. J.(1999), the marital satisfaction scale developed by Choi G. Y.(1999) ; and the health status scale developed by Kim S. Y. (1991). SPSS PC+ was utilized for data analysis. Data were analysed according to frequency and percentage, mean and standard deviation, t-test, ANOVA, Sheffe' s test and Pearson' s correlation coefficients and stepwise multiple regression. The reliability of the tools was tested by Cronbach's $\alpha$ : and it showed reliability scores of 0.88(for the meaning of life tool), 0.81(for the self-esteem tool), 0.94(for the marital satisfaction tool) and 0.78(for the health status tool). The results were as follows: 1) The scores showed that middle-aged women had a moderate level of meaning of life, with a mean of 30.31 and standard deviation of 6.24 (with values ranging from 12.00 to 48.00). The scores showed that middle-aged women had a moderate levels of self-esteem, with a mean of 28.92 and standard deviation of 4.67 (with values ranging from 10.00 to 40.00). The scores showed that middle-aged women had a very low level of volunteer activity, with a mean of 0.87 and standard deviation of 0.93(with values ranging from 0.00 to 1.00). The scores showed that middle-aged women had a moderate level of satisfaction in their marriages, with a mean of 31.99 and standard deviation of 7.84(with values ranging from 12.00 to 48.00). The scores showed that middle-aged women had a moderate level of health status, with a mean of 6.63 and standard deviation of 1.57(with values ranging from 3.00 to 9.00). 2) There was a statistically significant difference of the meaning of life of middle-aged women according to their religion(F=8.930, p=.000), christian ($31.94{\pm}5.96$) had more meaning th life than buddhists ($28.40{\pm}6.23$). 3) There was a statistically significant correlations between the subject' s self-esteem and the her meaning of life(r=0.477, p=0.000), the subject' s level of volunteer activity and meaning of life(r=.428, p=.000), her level of marital satisfaction and meaning of life(r=.417, p=.000), and her level of health status and meaning of life(r=.261, p=.000) among these middle-aged women. 4) Self- esteem was the highest factor influencing the level of meaning of life in middle-aged women. 40.0% of the total variance of levels of meaning of life by was dependent on self-esteem, volunteer activity, marital satisfaction and health status. In conclusion, the higher the self-esteem and levels of volunteer activity, marital satisfaction, and health status of middle-aged women, the higher the meaning of life for them. Therefore, it is necessary to elevate levels of the self-esteem and volunteer activity, marital satisfaction and health status in order to help middle-aged women have more meaning of life.

  • This is the report of a food consumption survey of 193 members of 30 farm families in three rural villages of Korea. From a total of 188 households of the three villages, namely Wolgok in Kyunggi Do Province, Wachon in Kangwon Do Province, and Sobong in Cholla Namdo Province, 30 households were chosen for the survey. Four consecutive seasonal surveys, beginning in the autumn, November 1974 and finishing with the summer, August 1975, were made and each survey covered three consecutive days. The Precise Weighing Method was used in evaluating the kinds of food and nutrient intakes of the subjects. This method entails the accurate weighing of all foods by the investigator just prior to their consumption by the subjects under investigation. This survey was male to determine the actual food eaten by the members of these farm families at each season of the year, and to note any special differences in the foods consumed. The results obtained are summarized as follows: Food Intake The traditional ordinary diet of Korean farmers consists mainly of rice and other cereals as staple foods, and simple subsidary foods. The nutritional shortcomings of rice as a staple food are evident in the subclinical status of nutritional deficiencies. The mean consumption of cereals and their products was very high and it was more than half of the daily total food intake throughout all the seasons. The consumption of animal food, fruits, and fat by the farmers was very low. Fruit intake during winter and spring was almost nil. One of the special foods in the Korean dietary pattern is Kim-chi, a variety of pickled and fermented vegetables. The mean intake of Kim-chi during autumn and winter was very much higher than the other seasons. Korean farmers have difficulties in balanced year-round supply of food due to seasonality of food production and lack of food preservation. As nutrition problems of Korean farmers are highly influenced by seasonal variations, the expansion of an appropriate food preservation and storage programme should be encouraged. Special consideration should be given to new methods of preservation, the types of foods preserved, and production and consumption of nutritionally valuable foods for the improvement of the nutritional status in rural communities. Nutrient Intake Average adult rates for calorie and protein in the three study areas were 0.80 and 0.87 respectively, with little variations by villages. The adult caloric intake in averaged 2,928 kcal for autumn, 2,662 for winter, 2,673 for spring, and 2,760 for summer. Cereals contributed most of the total calories. In terms of the recommended daily dietary allowances for the Korean given by the Korea FAO Association, the diets in this survey were adequate except in the winter and spring. The protein intake averaged from 76.4 grams in autumn to 83.4 grams in summer and was near the recommended allowance, but a relatively large proportion of the total protein came from cereals and their products. The fat intake was unsatisfactory, ranging from 19.2 grams to 29.3 grams for the four seasons, and the consumption during farming season was higher than other seasons. It is apparent that the diet of the Korean farmers should be supplemented by calcium during autumn and winter. The highest calcium intake, with a mean of 583.5 milligrams, was recorded in summer. The mean intake of iron ranged from a low of 9.2 milligrams in the autumn to a high of 15.0 milligrams in the spring and it was satisfactory for all seasons. Among the vitamin group, the daily average intakes of vitamin A, thiamine, riboflavin, and ascorbic acid were lower than the desired intake throughout all the seasons. The mean vitamin A intake as ${\beta}-carotene$ ranged from a low of 2,807.8 IU to a high of 5,221.0 IU. The thiamine intake ranged from 0.98 milligrams to 1.19 milligrams, while mean riboflavin intake ranged from 0.92 milligrams to 1.13 milligrams. Ascorbic acid intake was 37.3 milligrams, the lowest, and the highest 47.8 milligrams. Niacin intake among Korean farmers was higher than the recommended allowance throughout all the seasons, and the mean intake ranged from 18.3 milligrams to 25.8 milligrams. The main character of the Korean farmers' diet has been found low in quality of protein and high in carbohydrate. Attention should be paid to the low intake of vitamin A, thiamine, riboflavin, and ascorbic acid among Korean farmers.

  • Four experiments were conducted to investigate the effect of organic or inorganic acid supplementation on the growth performance, nutrient digestibility, intestinal measurements and white blood cell counts of weanling pigs. In growth trial (Exp I), a total of 100 crossbred pigs ({$Landrace{\times}Yorkshire$}${\times}$Duroc), weaned at $23{\pm}2$ days of age and $7.25{\pm}0.10kg$ average initial body weight (BW), were allotted to 5 treatments by body weight and sex in a randomized complete block (RCB) design. Three different organic acids (fumaric [FUA], formic [FOA] or lactic acid [LAA]) and one inorganic acid (hydrochloric acid [SHA]) were supplemented to each treatment diet. Each treatment had 5 replicates with 4 pigs per pen. During 0-3 wk, average daily gain (ADG), average daily feed intake (ADFI) and feed efficiency (G/F ratio) were not significantly different among treatments. However, pigs fed LAA or SHA diet showed improved ADG by 15 or 13% respectively and 12% greater ADFI in both treatments compared to CON diets. Moreover, compared to organic acid treatments, better ADG (p = 0.07) and ADFI (p = 0.09) were observed in SHA diet compared to pigs that were fed the diet containing organic acids (FUA, FOA or LAA). However, during 4-5 wk, no differences in ADG, ADFI and G/F ratio were observed among treatments. Overall, ADG, ADFI and G/F ratio were not affected by acidifier supplementation. Although it showed no significant difference, pigs fed LAA or SHA diets showed numerically higher ADG and ADFI than pigs fed other treatments. In metabolic trial (Exp II), 15 pigs were used to evaluate the effect of acidifier supplementation on nutrient digestibility. The digestibility of dry matter (DM), crude protein (CP), crude fat (CF), crude ash (CA), calcium (Ca) and phosphorus (P) was not improved by acidifier supplementation. Although the amount of fecal-N excretion was not different among treatments, that of urinary-N excretion was reduced in acidsupplemented treatments compared to CON group (p = 0.12). Subsequently, N retention was improved in acid-supplemented groups (p = 0.17). In anatomical trial (Exp III), the pH and $Cl^-$ concentrations of digesta in gastrointestinal (GI) tracts were not affected by acidifier supplementation. No detrimental effect of intestinal and lingual (taste bud) morphology was observed by acidifier supplementation particularly in inorganic acid treatment. In white blood cell assay (Exp IV), 45 pigs were used for measuring white blood cell (WBC) counts. In all pigs after LPS injection, WBC counts had slightly declined at 2 h and kept elevating at 8 h, then returned to baseline by 24 h after injection of lipopolysaccharide (LPS). However, overall WBC counts were not affected by acidifier supplementation. In conclusion, there was no difference between organic and inorganic acidifier supplementation in weanling pigs' diet, however inorganic acidifier might have a beneficial effect on growth performance and N utilization with lower supplementation levels. Furthermore, inorganic acidifier had no negative effect on intestinal measurements and white blood cell counts in weanling pigs. These results suggested that inorganic acidifier might be a good alternative to organic acidifiers in weanling pigs.

  • The theories of Korean Public Art originated by the artists who were against dictatorship and they associated with democratic politicians. They criticized the Fine art that were supported by the dictatorship and gave their efforts for restoration of 'resistance paintings(against dictatorship)', 'proletarian painting', 'realism painting'. In addition, they participated new social ideology(democracy) movement and demonstrated for their rights in arts. These became the main kernel the public art theory was initiated. The public artists splitted into several different parts and participated in the democratic social movement as well as the art movement for freedom. They opened various art exhibitions within different genre, diverse space for various art section such as an exhibition hall, a factories, a university, or a congregation square. Furthermore, the public art theorists published their divergent views through newspaper/broadcasting or unauthorized printed materials. Most of the public artist and the theorists kept their relationship strongly until 1985, the time when 'National Arts Association' started. In 1983 and 1984, they were clearly separated into two parts; artists(move only in art museums) and activists(move in public spaces like school, convention square etc). Their ideological separation also took out national problems. The division; professional artists and armatures, became the social issue as a social stratification matter. And in creating method, there are also other conflicts; critical realism, and public realism as well as western painting and traditional one. These kinds of separation and conflicts made different Public artists associations, under divergent names; 'Reality and Speak'(R&S), 'KwangJu Art Association', 'Durung', 'Dang(Land)', and 'Local Youth Students Association'. In addition, their ideology and pursuit toward art movements were very difference. However, the differences and conflicts weakened When the oppression of democratic education from new dictatorship(Pres. Jun, Doo Hwan) came out. In August. 1985 the government opened to the public so called, 'The draft of School stabilization law'(Hankwon Anjung Bup) to control the teachers' rights and that initiated bigger street demonstration and conflicts between police and educators. In November.1985, assembly meeting of National Arts Association in democracy opened as 'ONE' combined organization. In this presentation, I'd like to summarize the stream of art movement until 1984, and clarify the main art theories that lead the Public Art Movements in 1980s. The main theories in 1980s are crucial because they become the origin of public art theories. This presentation started with O,youn's "Hyunsil Dong In the first declaration" and explained the absent of practice in 1970s. In addition, Won, Dong Suk 's theory was mentioned as all over struggles in theories before 1980s. GA and R&S 's founding declarations in 1970s were the start of public art theorists' activities and this article reported the activities after the declarations. First, realism base on the consciousness of reality. Second, practice art democratization based on the ideology. Third, the subject of public art movement based on understanding people's social stratification structure. Fourth, the matters of national forms and creative ways in arts based on showing reality. Fifth, the strong points in arts that the practitioners accepted. About the public art theories around 1984, I discussed the dividing point of public art theories that were shown in 'generation theory', 'organization theory', and 'popularization theory' by the practitioners. The public realism theory that subjects the contradiction of reality and point out the limits of critical realism not only showing the new creative ways but also giving the feeling of solidarity to the public art activist groups. After that, public art movements expressed 'Dismentlement of Capitalism' and 'Public revolution'. In addition, the direction of public art movements were established strongly. There were various opinions and views during the start and formation of the public art theories. The foundation of theorists activities derived from the practitioners who had the concept based on stratification and nationalism. The strong trend of group division spreaded out by practitioners who opened art work together in factories, universities, squares and rural areas. Now many lively active practitioners are gone to the other field not related with arts, and others join into professional art field not public art one with unknown reason. The theorists have the same situation with the practitioners. It means to me that theory always have to be based on the practice.

  • From the study on Doo-Jong Kims view of history about the early Korea$(Korea\;herewith\;stands\;for\;Korea\;dynasty\;A.D.918{\sim}1392)s$ Medicine, I came to a conclusion as follows. 1. Doo-Jong Kim is stressing on the fact that Early Koreas Medicine inherited from Shilla dynasty and seemingly expressing the pride of national medical science. But actually he distorted the Koreas independent growth with flunkeyism and insisted that Koreas medicine only took over Shilla dynastys which based on Chinese Tang dynastys medical science. As a result, Koreas medicine was blurred and evaluated as nothing but Tangs medicine. But, the reasons of Doo-Jong Kims viewpoints were not based on the fact, but on his speculation. 2. About the medical system, Doo-Jong Kim viewed that Korea copied Chinese Soo & Tangs medical system, But the fact is that Korea only borrowed a part of Chinese medical systems name, for examples, Tae-I-Gam, Sang-Yak-Kook, Sang-Sik-Kook, etc., and its actual functions were different and grew in Koreas own way, As a result, the titles or roles in the system were very different from those of Chinas. Especially, Korea saw much development in Science of Acupuncture and Moxibustion that there was a specialist on Acupuncture, called I-Chim-Sa, and even had much influences on Chinese Acupuncture and Moxibustions growth, exporting Hwang-Je-Ne-Kyong to Chinese Song dynasty. 3. About the education system of medicine, Doo-Jong Kim viewed that Koreas medicine was only a copy of Shilla dynastys which was based on Chinese Tang dynastys, taking the medical examination curriculum as an example. The fact is that Tangs medical curriculum was three, Bon-Cho, Kab-Ul, Maek-Kyong, Shilla had seven, Bon-Cho-Kyong, Kab-Ul-Kyong, So-Moon-Kyong, Chim-Kyong, Maek-Kyong, Myong-Dang-Kyong, Nan-Kyong, and Korea had ten, So-Moon-Kyong, Kab-Ul-Kyong, Bon-Cho-Kyong, Myong-Dang-Kyong, Maek-Kyong, Dae-Kyong-Chim-Kyong, Nan-Kyong, Ku-Kyong, Ryu-Yon-Ja-Bang, So-Kyong-Chang-Jeo-Ron. Simply considering this, it is so clear that Koreas medical curriculum was much more upgraded one than that of China. 4. About the examination system for civil service, Doo-Jong Kim expressed that Shilla dynasty did not have such system, and only expounded knowledge of Shilla medicine, In case of China, Tang danasty Hyang-Kong was only a qualification test for civil service, which the result was completely dependent on applicants social status, Song danasty examination system was composed of three steps of Hyang-Si, Sung-Si, Jeon-Si (See Note1), but it stuck to formality by having Jeon-Si of anti-fraudulence use. On the other hand, examination system for civil service in Korea dynasty started in 958 by an advice of Ssang-Ki, Chin-Si in 977 and K대-Ja-Si (See Note 1), a kind of Hyang-Si, in 1024., Three steps of examination system made employment for civil service strictly fair, Moreover, it was possible for offsprings of concubine to be an applicant. These easily explain that the examination system of Korea dynasty was more upgraded one than that of China, Tang & Song dynasty. Hyang-Si : Exam in local area Sung-Si : Exam in province for those who passed Hyang-Si Jeon-Si : Exam held with Koea Kings supervision for those who passed Hyang-Si Keo-Ja-Si : Selective exam in local area like Hyang-Si. From the reasons above, it is clear that Doo-Jong Kim was much biased by flunkeyism through Japanese colonialisam and expressed his view on Korea Medical History based on such theory of heteronomy and stasis. Moreover, without rigid historical evidence on records, he distored the fact by translating incorrectly on his purpose. Therefore, Doo-Jong Kims Korean Medical History must be reevaluated through rigid historical research and his mistranslation should be corrected.
