김포시와 고양시 일대의 한강하구 지역은 우리나라에서 재두루미의 가장 중요한 월동지 및 중간기착지로 알려져 있지만, 이 지역의 조류 서식환경은 심각한 개발압력과 인간의 간섭으로 인해 지속적으로 나빠지고 있다. 따라서 본 연구에서는 2007-2008년과 2011-2012년의 월동시기에 본 지역에 도래하는 재두루미를 대상으로 월동 개체군 크기 변화와 월동지역 내에서 과거와 현재의 취식지역 이용 현황 등을 조사하여 개발행위가 이들의 서식에 미치는 영향을 확인하였다. 본 지역에서 월동하는 재두루미 개체군은 평균 124.9개체(2007-2008년)에서 59.0개체(2011-2012년)로 감소하였으며, 주요 취식지역에서 확인된 개체수는 평균 77.7개체에서 24.1개체로 감소하여 월동개체군의 감소폭에 비해 주요 취식지역의 이용 개체수의 감소폭이 더 크게 나타났다. 유형별 분석에서는 가족군에 비해 무리군의 개체수가 많이 감소한 것으로 나타났으나, 홍도평 지역의 가족군 이용 개체수는 변화가 나타나지 않았다(Mann-Whitney test. Z=-0.26, p=0.979). 그리고 과거 다수의 재두루미가 주요 취식지역으로 이용하였던 송포동과 평동지역은 2012-2013년 조사에서는 거의 이용하지 않는 것으로 나타났다. 이는 위 지역의 개발행위(예: 제 2자유로 건설 등)와 깊은 연관성이 있는 것으로 생각된다. Han-river estuary in Gimpo and Goyang city is well known as one of the most important wintering and stopover sites for migrating White-naped Crane (Grus vipio) in Korea. Nowadays, habitat quality of this area is getting worse due to serious development pressure and high human disturbances. So, we wanted to know whether development actions affected total wintering population change in Han-river estuary and feeding group pattern of White-naped Crane in main feeding habitats between the 2007-2008 and 2011-2012 wintering period. Average wintering population was decreased 124.9 to 59.0 and population of main feeding site also decreased 77.7 to 24.1. But decrease rate of main feeding site population was higher than total wintering population. Non-family feeding population was more decrease than family feeding population in the flock type analysis. But family feeding population of Hongdopyong was maintained from past and present (Mann-Whitney test. Z=-0.26, p=0.979). However, almost all White-naped Crane din not use both feeding sites, Pyong-dong and Songpo-dong, where were deteriorated habitat quality by human act.

In this paper, a fuzzy logic controller is designed for speed control of a hydraulic inverter elevator. Mathematical modeling of an elevator actuated with hydraulic system is presented and the friction characteristics of a cylinder is examined, which may cause the abrupt increase of the acceleration in the zero-crossing speed region. Simulation results show that the proposed fuzzy logic speed controller yields a better control performance than conventional PID controller.

Stressors which dance specialty university student have been suffered from during activity in dance were analyzed through open-questionnaire, the participants in this survey were 228 dance specialty university student, sort questions according to the affinity and similarity of them in the aspects of conception, questionnaire was summed up in six factors and twenty questions. Arranged twenty questions were determined by the fifth levels of Likert's type scale to be good for responses. As the result of analysis of responded contents, they were sorted as main six factors like that university professor, training, school, finance, individual, rest. As Jim Taylor told, dancers are apt to have disease and injuries when dancers are under the stress, and those who have abnormal increase of decrease in one's own weights can have more stress. The way of conducted a good performance by dance specialty university student is that dancers should have responsibility as worker and have pride as artist, many study and analysis will be necessary if there are any other in actual circumstances or not in actual circumstances.

In shooting competition, the anxiety in competition can have a great effect in the players' records. To improve their record, they chose the group hypnosis. A subject experimented 24 boy and girl students dividing them two groups, one is for this experiment (Male , Female 5), the other for comparison(Male 8, Female 4). they were investigated for three weeks. Dependent variables are the trait of competition anxiety and competition anxiety state which was developed by Martens. Mr. Taek-Yeol Kwon. changed and reinforced them to be suitable for the shooting players. Erickson's hypnosis was used for this investigation.. The experimental group had T-test, seperated before-experiment and after-experiment and comparison group, before and after comparison. Furthermore the experimental group and comparison group had T-test before experiment and before comparison, after experiment and after comparison using the statistic program SPSS-10.0. According to the result in the analysis of the mutual comparison shows that the effect of Erickson's group hypnosis didn't have any statistical differences in anxiety trait, anxiety state abd players' records. Therefore my study reveals that the result of Erickson's group hypnosis for three weeks shows that Erickson's method is needed to dissolve the competition anxiety, improving their record of the shooting players.

Backgrounds : The purpose of this study was to review the clinical features, treatments and prognosis of borderline malignant tumors of the ovary. Methods : For a period of seven years, from 1999 to 2005, 208 patients were diagnosed with ovarian tumors. Of the 208 patients, 40 were diagnosed with borderline malignant ovarian tumors. Forty patients with borderline malignant tumors of the ovary were admitted, operated on and diagnosed through confirming with postoperative histopathological study at the department of obstetrics and gynecology, Kosin University Gospel Hospital. The data was collected retrospectively and all charts were reviewed. Results : The incidence of borderline malignant ovarian tumor was 17.7% (40/208). The age distribution was between 17 and 74 years old, the mean age being 39.2 years old. As for the parity distribution of borderline malignant tumor, nulliparity was most common with 16 patients (40.0%). The most common chief complaint was palpable mass and abdominal distensions (80.0%). Histologic subtypes were mucinous in 35 cases (87.5%), serous in 4 cases (10.0%). and mixed in 1 case (2.5%). The mean size of mucinous types tumors was larger than that of serous types tumors (18.2cm vs 13.2cm). According to the FIGO classification, 33 cases (83.3%) were stage I, 3 cases (7.5%) were stage II, 3 cases (7.5%) were stage III, and 1 case (2.5%) was stage lV. Twenty two patients (55.0%) underwent conservative surgery (unilateral salpingoophorectomy or cystectomy). Eighteen patients (50%) were treated with total abdominal hysterectomy and bilateral salpingoophorectomy. 12 cases (30.0%) received 6 cycles of adjuvant postoperative chemotherapy, and 16 cases (40.%) received 3 cycles of adjuvant postoperative chemotherapy. 12 cases (30.0%) did not receive adjuvant postoperative chemotherapy. 3 cases were lost during follow up. All patients were alive and were followed up on from 1 month to 52 months. Conclusion : Borderline malignant tumors of the ovaries constitute approximately 17.7% of epithelial ovarian malignancy and occur in young age those comparing with invasive cancer. It is mostly seen in mucinous and serous types and most of them are diagnosed at an early stage making definite treatment possible and also increasing the survival rates. Adjuvant postoperative chemotherapy seemed to lower chronic recurrence but isn't related to survival rates.

Intrauterine devices(IUDs) remain one of the main methods of choice for birth control over the world, especially in developing countries. Uterine perforation is a rarely observed complication. A misplaced intrauterine device can migrate to various positions in the pelvic or intra-abdominal cavity, which may cause a range of complications and morbidities. The currently accepted treatment of choice for IUDs is its removal by surgical laparoscopy or laparotomy. We report one case with misplaced IUD in the omentum, followed by a review of literature.

By examining the changes of the records resulting from the menstrual cycles of female weight lifters, this study tries to control their conditions and to provide the basic materials which are necessary to overcome the negative aspects of psychological, physical changes during menstration. The subjects of this study are 20 female weight lifters of a women high school in K district. We have measured for 3 months their records of the snatch and the jerk on the 5th day before, the 3rd day during, and the 7th day after the menstruation. The records of each level of the experiment and those of each phase of the menstruation are put into the One-Way ANOVA analysis : and on the results regarding α=0.5 the post-investigation is persecuted on the Student-New man-Keuls Test. The conclusion of the study is as follows : 1.The record of the snatch of the 48kg class is the highest after and the lowest before the menstruation (P< .05) . In the 56kg class the record after the menstruation is higher than the record before and during the menstruation(P< .05). 2.The record of the jerk for both(48kg and 56kg) classes is the highest after the menstruation, and the record during it is next, and the record before it is the lowast(P< .05) . 3.The total record is also higher the menstruation than before or during the menstruation for both weight classes(P< .04) .

This study was carried out to investigate the antioxidant activities of Dansam (S. miltiorrhiza). The Dansam (S. miltiorrhiza) was extracted with ethanol and methanol, and the extracts were fractionated with hexane, chloroform, ethyl acetate and butanol and water, in that order. The antioxidant activities of Dansam (S. miltiorrhiza) were determined by measuring the radical scavenging effects, using the 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) method. The electron donating ability was shown to be about 50% (IC50) at concentration of L-ascorbic acid, Dansam that reflected eliminatory effect by 50% were 9.48㎍/㎖, 8.28㎍/㎖ and 12.59㎍/㎖ respectively. According to the results of the above antioxidation experiments, those for the group with the added Dansam showed a decreased oxidation, but the antioxidation increased with time. With a storage temperature of 60℃ for 5 days, the acid value for the relative antioxidant activities were higher than in the Control group. The peroxide values for the relative antioxidant activities were also higher than in the Control group. The TBA values for the relative antioxidant activities were higher than in the Control group.

OBJECTIVES: To discern in advanced uterine cervical cancer whether the hyperfractionation is more effective in tumor control and in reducing radiation complication rates than the simple fractionation. METHODS: We retrospectively reviewed the medical records of 184 patients with advanced cervical cancer at our hospitals from January 2000 to December 2004. All patients were treated with radiation, 114 patients with simple fractionation, and 70 patients with hyperfractionation. RESULTS: Mean age was 55.4 years at baseline study. Complications were occurred in 90 patients of the 184 patients who treated with radiation therapy. Of these, 48 patients suffered from gastrointestinal complications, 24 patients suffered from genitourinary complications and 18 patients had both complications. Complications were occurred in 72 cases in simple fractionation group and 40 cases in hyperfractionation group. 77 patients had acute complications and 13 patients had chronic complications. There was no statistically significant difference between two groups (P = 0.772). Mild complication were occurred in 75 patients and severe complication were occurred in 15 patients, there was no statistically significant difference in two groups (P = 0.495). 66 patients had gastrointestinal complications and 42 patients had genitourinary complications, there was no statistical significance in two groups (P = 0.910). CONCLUSION: Many complications were occurred in patients who treated with radiation therapy, but there was no statistically significant survival and complication difference in two groups. Further research is needed.
