복숭아 유과의 이용 가능성 탐색을 위하여 복숭아 유과과육의 품종에 따른 성분 함량 및 품질특성을 조사하여 비교 분석하였다. 품종별 복숭아 유과(용택골드, 천중도백도, 마도카, 몽부사, 장택백봉, 홍백)의 외형적 특성을 비교한 결과 전체적으로 마도카가 가장 크고 몽부사가 가장 작은 것으로 나타났다. 일반성분을 측정한 결과 몽부사에서 수분함량이 가장 낮았으며, 조단백 함량은 장택백봉 가장 높아 조단백 함량이 가장 낮은 마도카와 유의적으로 차이를 나타내었다. 조지방 및 조탄수화물 함량에서는 품종 간 큰 차이가 없었으며, 조회분 함량은 마도카에서 0.69%로 다른 품종에 비하여 높은 함량을 나타내었다. 품종별 복숭아 유과의 pH를 측정한 결과 다른 품종과 비교하여 천중도백도에서 유의적으로 높게 나타났으며, 당도 실험 결과에서는 홍백이 다른 품종에 비하여 유의적으로 낮은 당도를 나타냈다. 색도 중 L값은 장택백봉에서 가장 높았고, a값은 전체적으로 -5 이하의 음의 값을 보이며 홍백에서 가장 높았으며, b값은 마도카에서 가장 높았다. 품종별 복숭아 유과의 경도는 홍백, 장택백봉, 천중도백도, 마도카, 용택골드, 몽부사 순으로 전반적으로 백도가 황도에 비해 높은 경도를 보였다. Vitamin C 함량을 측정한 결과에서는 품종에 따른 유의성을 보이지 않았으며, 환원당 함량은 6.34% 이상의 높은 수치를 보여 가공품 및 식품산업 소재로 사용되기에 부족함이 없다고 사료되었다. 따라서 현재 복숭아 유과가 거의 활용되지 못하고 전량 폐기되고 있는 실정을 감안해 볼 때 산업적 가치가 높다 사료되므로, 복숭아 유과의 기능성 및 생리활성 규명 등을 통한 미이용 폐자원의 활용도를 높일 수 있는 추가적인 연구가 필요할 것으로 생각된다.

This study purports to examine sociodemographic characteristics and those factors associated with osteoarthritis in women experiencing the disease in order to make suggestions for the prevention and management of osteoarthritis in women. The subjects were 143 women who were diagnosed to have osteoarthritis and under follow-up care at an outpatient department of a university-affiliated hospital. The data were collected through personal interviews by using the structured questionnaire between October 6 and October 24, 1997. The degree of daily living activities was measured with 24 items, which were made based upon Katz Index, Barthel Index and Functional Status Index. Each item has 4 response categories : (1) being able to do alone with any difficulty, (2) being able to do alone with some difficulty, (3) being able to do alone with the help of a person or an instrument, (4) not being able to do at all. The data was analyzed with correlation analysis, t-test, ANOVA, and regression analysis. The results are summarized as follows : 1. As for the age of the subjects, 59.4% were between 45 and 64 years, while 28% were 65 years and above. The subjects having religion were 71.7% and 44.1% of the subjects were protestants. The educational level was low : 31.5% graduated from elementary school, while 30.1% had no formal education. Those married subjects were 72%. Fifty nine percent of the subjects evaluated their economic status as middle class. 2. Those people from whom the subjects currently receive some help were spouses in 35.8% of the subjects. Likewise, 50% of the subjects indicated spouse as the people from whom they want to receive help. 3. The score of the ability of daily living activities ranged between 48 and 96, with the mean of 78.94. Those means of physical activity, ADL(activities of daily living) and IADL(instrumental activities of daily living) were 14.89, 13.97 and 50.09, respectively. Except for the items of carrying heavy stuff and of washing clothes in the sitting position the subjects showed independence in more than 90% of the items, where Independence is defined as being able to do alone or with the help of a person or an instrument. 4. The increase in age was a significant predictor of the decrease in the ability of daily living activities. Those graduated from middle school and above showed a significantly higher degree in the ability of daily living activities than those with less educational level. The married women revealed significantly higher scores in physical activity, ADL, and IADL than the unmarried ones. The ability of daily living activities was not significantly related to having religion, economic status and living with family. 5. The average duration of experiencing osteoarthritis was 4 years and 7 months. Regarding the site of the onset, 65% of the subjects indicated knees. The women with osteoarthritis for less than 3 years were 65%. The ability of daily living activities was significantly different by the duration of illness : the longer the duration of illness, the less the ability of activities. The above findings suggest the need for developing those programs for prevention disabilities in performing daily living activities and for managing diseases targeting the women of middle and old age, with low educational level, and with unmarried status. In addition, there should be developed an instrument for measuring the ability of daily living activities which reflects daily lives of Korean women with osteoarthritis in order to examine comprehensive effects of osteoarthritis on women's daily lives in this country.

This study was carried out to investigate the effect of the timing and dose of human chorionic gonadotropin(hCG) on oocyte recovery, in vitro fertilization, and preimplantation development in superovulation of mouse. F1 hybrid($C57BL{\times}CBA$) mice were obtained and superovulation was induced in female mice by sequential intraperitoneal injection of PMSG and hCG. In the first series of experiments, mice received 5 IU of PMSG given intraperitoneally, and 48 hours later were injected 1 IU, 5 IU, or 10 IU of hCG respectively. In the second series of experiments, mice received 5 IU of PMSG given intraperitoneally and were injected 5IU of hCG 36, 48, or 60 hours later respectively. 1. When the mice received 5 IU of PMSG given intraperitoneally and 48 hours later were injected 1 ItT, 5 IU, or 10 IU of hCG respectively, there were no differences in the total number of the oocytes obtained from the three experimental groups. When the cultures were examined 48 hrs after the termination of insemination the proportion of unfragmented oocytes which had developed over two-cell stage was observer to be lowest in 10 IU hCG group. When the cultrues were examined 120 hour after termination of insemination the proportion of embryos which had developed to the blastocyst stage was observed to be significantly higher in 10IU hCG group than 5IU hCG group(p<0.05), but there was no difference between 10 IU hCG group and 1IU hCG group. 2. When the mice received 5 IU of PMSG and were injected 5 IU of hCG 36, 48, or 60 hours later respectively, there were no differences in the total number of oocytes obtained from the three experimental groups. When cultures were examined 48 hour after the termination of insemination the proportion of unfragmented oocytes which had developed over two-cell stage was observed to be significantly lower in 36 hour interval group than 48 hour interval and 60 hour interval group(p<0.05). When the cultures were examined 120 hour after termination of insemination the proportion of embryos which had developed to the blastocyst stage was found to be higher in 60 hour interval group than 36 interval or 48 hour interval group (P<0.05), and the proportion of hatching blastocyst was found to be higher in 60 hour interval group as well. In this study, it was concluded that the administration of adequate dose of hCG, and long (60 hour) PMSG-hCG interval were necessary in superovulation of mice($C57BL{\times}CBA$) in order to get a large number of oocytes which had an early oocytes which had an early embryonic developmental capability when fertilized in vitro, and especially it had better have been avoided to administer a large dose of hCG.

Background: This study aimed toanalyze the risk behavior for cervical cancer (CC) and the human papillomavirus (HPV) prevalence and resolution among women who received care through the private healthcare network of a municipality in southern Brazil. Materials and Methods: This descriptive and retrospective study was conducted with 25 women aged 20 to 59 years who received care through the private healthcare network and were treated at a specialty clinic in the period from January to December 2012 in a municipality in Northwest Parana, Southern Brazil. Data from medical records with cytological and HPV results were used. Following treatment, these women were followed-up and reassessed after 6 months. Data were statistically analyzed using the t-test and chi-squared test at a 5% significance level. Results: The mean age of the studied women was $27.8{\pm}7.75$ years old, and the majority were married, with paid employment and were non-smokers. The mean age at menarche was $13.0{\pm}0.50$ years old, and the mean age at first intercourse was $17.5{\pm}1.78$ years, with only 8.0% (2) initiating sexual activity at an age ${\leq}15$ years old. The majority had 1 to 2 children (60.0%), while 88.0% reported having had one sexual partner in their lifetime, and all the women were sexually active. A total of 68.0% used a hormonal contraceptive method. All the women had leukorrhea and pain and were infected by a single HPV type. Regarding the lesion grade, 80.0% showed high risk and 20.0% low risk. The most prevalent high-risk HPV strain was 16. Conclusions: These findings provide relevant information on HPV risk factors and infection, as well as the treatment and 6-month follow-up results, in economically and socially advantaged women with no traditional risk factors, corroborating previous reports that different risk factors may be described in different populations. Thus, this study reinforces the fact that even women without the traditional risk factors should undergo HPVmonitoring and assessment to determine the persistence of infection, promoting early diagnosis of the lesions presented and appropriate treatment to thus prevent the occurrence of CC.

This paper constitutes a descriptive investigation and used a structured questionnaire to investigate nurses' and doctors' recognition of cancer patients. The subjects were extracted from the medical personnel working at the internal medicine, the surgery ward, the obstetrics and gynecology department, the pediatrics department, the cancer ward, and the emergency room of five general hospitals located in Seoul and Gyeonggi Province. The research lasted from August, 2001 to September 2001. Total 137 nurses and 65 doctors were included and made out the questionnaires directly distributed by the investigator. The study tool was also developed by the investigator and consisted of such items as the demographic and social characteristics, the medical personnel's recognition degree of cancer and cancer patients, their recognition of the management of cancer patients, and their participation in a hospice. The results were analyzed using the SPSS Window program in terms of technological statistics, ranks, t-test, and ANOVA. The reliability was represented in Cronbach' α=.75. The nurses' and doctors' recognition degree of cancer and cancer patients had an overall average of 3.86 at the 5 point-scale. The items that received an average of 4.0 or more included 'Medical personnel should explain about the cancer cure plans to the cancer patient and his or her family', 'A patient whose case has been diagnosed as a terminal cancer should be notified of it, 'If I were a cancer patient, I would want to get informed of it,' and 'Cancer shall be conquered whenever it is'. In the meantime, the items that received an average of 3.0 or less was 'My relationship with the cancer patient's family has gotten worse since I announced his or her impending death.' And according to the general characteristics and the difference test, the recognition degree of cancer and cancer patient was high among the subgroups of nurses, females, married persons, who were in their 30s, who had a family member that was a cancer patient, and who received a hospice education. The biggest number of the nurses and doctors saw 'a gradual approach over several days'(68.8%) as a method to tell a cancer patient about his or her cancer diagnosis or impending death. Those who usually tell tragic news were the physician in charge(62.8%), the family members or relatives(32.1%) and the clergymen(3.8%) in the order. The greatest number of them recommended a cancer patient's home as the place where he or she should face death because they thought 'it would stabilize his or her mentality'(91.9%) while a number of them recommended the hospital because they 'should give the psychological satisfaction to the patient'(40%) or 'should try their best until the last moment of the patient's death'(30%). A majority of the medical personnel regarded 'smoking or drinking' and 'diet' as the causes of cancer. The biggest symptom of a cancer patient was 'pain' and the pain management of a cancer patient was mostly impeded by the 'excessive fear of drug addiction, tolerance to drugs and side effects of drugs' by medical personnel, the patient, and his or her family. The most frequently adopted treatment plan of a terminal cancer patient was 'to do whatever the patient or his or her family wants' to resort to a hospice' and 'to continue active treatment efforts' in the order. The biggest reasons why a terminal cancer patient went to see a doctor were 'pain alleviation' 'control of symptoms other than pain(intravenous supply)' and 'incapability of the patient's family' in the order. Terminal cancer patients placed their major concern in 'spiritual(religious) matter' 'emotional matters' their family' 'existence' and 'physical matters' in the order. 113(58.5%) of the whole medical personnel answered they 'would recommend' an alternative treatment to a terminal cancer patient mostly because they assumed it would 'stabilize the patient's mentality.' Meanwhile, 80(41.5%) of them chose 'not to recommend it mostly due to the unverified effects and high cost of it(78.7%). A majority of them, I. e. 190(94.1%) subjects said they 'would recommend' a hospice to a terminal cancer patient mostly because they thought it would help the patient to 'mentally prepare'(66.6%) Only 17.3% of them, however, had received a hospice education, most of which was done through the hospital duty education(41.4%) and volunteer training(34.5%). The follows are results of this study: 1. The nurses and the doctors turned out to be still passive and experience confusion in dealing with a cancer patient despite their great sense of responsibility for him or her. 2.Nurses and Doctors realize the need of a hospice, but an extremely small number of them participate in a hospice education or performance. Thus, a whole recognition of a hospice should be changed, for which purpose a hospice education for nurses and doctors should be provided. 3.Terminal cancer patients preferred their home to a hospital as the place to face their impending death because they felt it would bring 'mental stability.' And most of nurses and doctors think it would be unnecessary for them to be hospitalized just for control of their symptoms. Accordingly a terminal cancer patient can be cared at home, and a home hospice care needs to be activated.

This study is aimed at identifying the national economic value of the irrigation facilities by reviewing the existing papers on economic values of the irrigation facilities and presenting current status of dual O & M problems of the irrigation facilities. This study suggested the unified O & M system rather than continuing the existing dual O & M system of irrigation facilities based on the surveyed results of the activities of irrigation fraternities in Chungnam Province. The findings and proposals for the successful unified and mono O & M system of the irrigation facilities are as follows: (1) Total number of irrigation facilities in the nation accounts for 67,582, while the total length of irrigation and drainage canals amounted to about 174,259km. On account of the total length of structural canals was estimated at 31%, much losses of water and much O & M costs have been inevitable for the full irrigation rice culture. In spite of the past heavy investment for irrigation facilities, the ratio of rain-fed and partially irrigated paddy fields accounts for 23% in 2003. Both Korea Agricultural and Rural Infrastructure Corporation (KARICO) and the city and Gun Governments have managed the irrigation facilities separately by irrigation fraternities. The KARICO have commanded 59% of irrigation paddy area with 18% of the total irrigation facilities, while the city and Gun governments covered 41% of irrigation paddy area with 82% of the existing number of irrigation facilities representing small and medium scale. (2) The 1999 demand prices of irrigation water per ton expressed in 2000 constant market price was estimated at 388 won, the supply price was amounted to 184 won per ton. Considering the supply and demand curve of the irrigation water, the existing irrigation facilities could not satisfy the demand of irrigation water. (3) In 1999, total present added value of the irrigation facilities during the economic life accounted for 48 trillion won, while total supply cost was 44.7 trillion won. The marginal benefit and cost ratio of irrigation water was 1.08. (4) The total O & M cost per year amounting to 681.1 billion won have been required to maintain and repair the existing irrigation facilities in Korea. For the successful unified O & M of irrigation facilities covering whole irrigated paddy field in Korea, 950 billion won of O & M costs are required to keep up the marginal benefit of irrigation water as 2,800 billion won per year. The total O & M cost as 950 billion won should be allocated 40%, 380 billion won for O & M costs of irrigation facilities and 60%, 570 billion won for improvement of irrigation facilities. (5) The study investigated and reviewed the present O & M status of the irrigation facilities by small and medium irrigation fraternities. Most of the farmers belong to the irrigation fraternities preferred not only unified O & M but also KARICO take-over of the whole O & M activities of the irrigation facilities. The prevailing O & M cost per 10a expended by the Corporation was amounted to 104,890 won, while that of city and Gun governments was only amounted to 4,600 won per 10a. regarding the small amount of O & M cost expended by city and Gun governments, it is evident that the existing irrigation system have been managed ineffectively and deteriorated the facilities comparing that of KARICO. In conclusion, the Government could not satisfied the demand of irrigation water by suppling water with existing irrigation facilities. Therefore new additional investment and financial support for irrigation water development should be made to convert rain-fed and partially irrigated paddy fields into fully irrigated ones. The operation and maintenance cost should be supported to keep the marginal values of rice production of existing irrigation facilities in the national economy and to modernize the obsolete irrigation facilities. By unifying the existing dual O & M systems, all the farmers belong to the irrigated paddy fields have to be equally benefited and could be increased their farm income and be stabilized their rural lives.

본 연구는 치주질환을 조기에 발견하고 예방하기 위해 20대의 구강보건지식과 구강위생관리능력이 치주건강상태평가에 미치는 영향을 비교 분석함으로써 국민의 구강보건관심도를 높일 뿐 아니라 치주건강증진활동에 지식과 정보를 제공하여 건강하고 효율적인 구강관리를 하는 데 기초자료를 제공할 목적으로 조사되었다. 포괄 치위생 관리 및 처치를 위하여 치위생과 실습실을 방문한 20대의 성인 130명을 대상으로 설문조사를 실시하고, 치주건강상태를 평가하였다. 일반적 특성, 구강보건지식, 구강위생관리능력과 치주건강상태평가의 연관성을 조사 분석하여 다음과 같은 결과를 얻었다. 1. 성별에 따른 잇솔질(p=0.030)과 구강위생용품(p=0.047)에 대한 구강보건지식은 통계적으로 유의하였고, 여성이 구강보건에 대한 지식이 높게 나타났다. 2. 성별에 따른 잇솔질(p=0.030)과 구강위생용품(p=0.047)에 대한 구강보건지식은 통계적으로 유의하였고 여성이 구강건강에 대한 지식이 높게 나타났다. 3. 성별에 따른 유두변연부착 치은염지수(p=0.047)와 지역사회치주지수(p=0.028)는 통계적으로 유의하였다. 남자의 유두변연부착 치은염지수, 지역사회치주지수는 여자보다 높았다. 학력에 따른 출혈지수(p=0.042)는 통계적으로 유의하였고, 고졸 이하가 가장 높았다. 4. 잇솔질(p=0.030), 치주질환(p=0.024)에 대한 구강보건지식이 치면세균막지수에 미치는 영향이 통계적으로 유의하게 나타났다. 잇솔질에 대한 구강보건지식($\beta$=-0.137)이 증가하면 치면세균막지수가 감소하고, 치주질환에 대한 구강보건지식($\beta$=-0.144)이 증가하면 치면세균막지수가 감소한다. 5. 잇솔질 총 횟수에 따른 유두변연부착 치은염지수는 2회가 가장 높았다. 잇솔질 방법에 따른 치면세균막지수는 묘원법이 가장 높았으며, 횡마법, 회전법 순으로 나타났다. 구강위생용품을 사용하지 않는 경우의 지역사회치주지수와 출혈지수가 구강위생용품을 사용하는 경우보다 높았다. 흡연의 경우 유두변연부착 치은염지수, 지역사회치주지수, 출혈지수가 흡연을 하지 않는 경우보다 높았다. 주 당 음주 횟수에 따른 지역사회치주지수와 출혈지수는 3회 이상이 가장 높았다. 구강보건교육을 경험하지 못한 경우의 유두변연부착 치은염지수가 구강보건교육을 경험한 경우보다 높았다.
