This study is an analysis and a plan for the improvement on a teaching method, a development of the teaching instruments in integrated subject of mathematics and natural science called "Inquiring Life". Thus this study is summarized as follows: (1) An analysis of the integrated textbook. ① The proportion of the time required for teaching mathematics and natural science is 2:1 in our curriculum. However, in the practical guide book of the Inquiring Life, it has been investigated that the time allotted for mathematics is 12 periods more than the time allotted for natural science, furthermore its significant difference is to appear in x^2=3.86 (p<0.05). ② It has been found that there is a meaning of the integration in the first-term text-book, because the quantity of the contents which is integrated in it is 48.7% of the whole. But there is a problem which must be corrected in the second-term textbook, because such quantity is merely 25.6% of the whole. ③ The time required for teaching a field "figures" was 12 periods (9.2%) of the whole in the textbook of the third revised curriculum (1973). However, since the time required for it in the new textbook is only 2.5 periods (2.0%), this is to show a significant difference in x^2=4.62 (p<0.05). ④ It is because of a emphasis on the problem-solving that the time required for teaching the field "relations" has increased more than that of the preceding textbook. ⑤ There is some resistance in "a reclassification of the shaped boards" and "a learning for preservation of a quantity" to construct a possibility of the learning achievment. ⑥ It is found that the contents and the expressions of the integrated textbook is suitable for our pupils, because, in a questionary investigation for their appropriateness, a significant difference is to appear in x^2=9.49 (p<0.05). (2) The teaching method of the integrated textbook. The integrated teaching method is verified to be effective for a group of the dull pupils by showing a significant difference with CR_M=1.99 (p<0.05). (3) A development of the teaching instruments in the integrated textbook. The integrated teaching instruments that are considered to be a interest of pupils, a acceleration of thoughts, a economic condition, a exactness, a convenience, a firmness and anewness, are efficient for our pupils. (4) An estimation for the integrated textbook. An integration of the curriculum and the revision of the form the pupils' cumulative records are demanded in order to get the good estimations for the integrated concepts.

A mailed survey with structured questionnaire was conducted to study the demand of private physicians who were operating their own clinics in the community to be a attending physician at the general hospital. The responding proportion was 21.6 percent of the 960 private physicians. A total of 207 responders : 65.2 percent wanted to be a attending physician. In particular, the physicians who were male, young, surgeon and teaching hospital careered after specialist were more highly motivated. The major activities what they wanted as a attending physician were medical care for the admission patients. They responded that the hospital charges for the medical services and the responsibility of malpractice issues should be fairly shared by attending physician and hospital according to their contributions. There is growing consensus that the need of attending physician at the general hospital will become wide spread, but little organizational preparation to assure the quality of medical care of attending physicians including training of resident physicians and students. In addition, the effective reimbursement system should be develop to compensate appropriately according to the medical achievement of the attending physicians.

Literally, the mean of Tae-gye is highest brook. And on the basis of the acupuncture theory, Tae-gye point is the Soo earth point and source point of the Kidney Channel as well. In addition, Tae-gye point is one of the Yang-Returning Nine points. We were trying to study bibliographically on the Tae-gye point because Tae-gye point can be used very broadly across the symptoms in the theoretical aspect described above. As a results, we found out that according to the classical books of acupuncture, Tae-gye point is entering point of the Meridian Water as a source point and can be used at both Kidney-Sufficient Syndrom and Kidney-Deficient Syndrom. And Tae-gye can be applied to the disease of kidney or bladder that is urogenital symtoms, Also, Tae-gye is an useful option of tooth-ache, asthma, indigestion, constipation, edema etc whose cause is related with decrease of Kidney ki.

Platelet aggregation is the final pathway of acute coronary syndrome such as acute myocardial infarction and unstable angina. Platelet glycoprotein IIb/IIIa is a membrane receptor for fibrinogen and yon Willebrand factor and it plays an important role in platelet aggregation and in the pathogenesis of acute coronary syndrome. It is known that polymorphism of the gene that encoding platelet glycoprotein IIb/IIIa(PI^A1/A2) is strongly related to acute coronary syndrome in Caucasian, but not in Koreans. We investigated relationship between platelet glycoprotein llb/Illa gene polymorphism and restenosis of coronary artery after angioplasty in Koreans. Total 371 patients(M=251. F=120) were enrolled. Angioplasty group comprised 143 patients who underwent coronary angioplasty, and in the angioplasty group, restenosis group comprised with the 65 patients who had restenotic lesion over 50% of luminal diameter in follow-up coronary angiography. Normal group comprised 153 patients who had no significant angiographic lesion and variant angina group comprised 75 patients who were positive in ergonovine test. Genomic DNA was extracted from peripheral arterial blood. To determine the frequency of P1^A1/A2 genotype, polymerase chain reaction(PCR) was done and the product was restricted with Mspl. 3%. agarrose gel electrophoresis showed restriction fragment length polymorphism. Clinical profile and risk factor were also reviewed. Among all 371 patients of study group, genotype of only one patients in restenosis group if is proven to be PI^A1/A2 heterozygote. All patients of normal study group, no restenosis group, and the other patients in restenosis group have an PI^A1 homozygote genotype. In our study, platelet glycoprotein IIb/Illa polymorphism has no relationship with restenosis of the coronary artery after angioplasty in Koreans. But the genotypic frequency of platelet glycoprotein IIb/IIIa gene polymorphism in Koreans is concordant with that of previous studies.

Coronary stent implacement is known as an effective treatment in the intimal dissection after percutaneous transluminal coronary angioplasty and the prevention of restenosis. However, In-stent restenosis still remains a major concern in clinical stenting. The stents were placed in 103 patients from July 1996 to March 1999 and performed follow-up coronary angiograms in 59(57.3%) patients. To identify the clinical, angiographic and procedurerelated variables 'which predict late restenosis within the stented artery, 59 patients(58.3±9.9, M:F= 41:18) were studied. The clinical characteristics of the patients were stable angina in 23(39.0%), unstable angina in 14(23.7%), acute myocardial infarction in 21(35.6%) and old myocardial infarction in 1(1.7%). Coronary stenting was performed in 1 patient(1.7%) for primary lesion, 50 patients(84.7%) for suboptimal results after PTCA, 6 patients(10.2%) for bail-out procedure, and 2 patients(3.4%) for restenotic lesions. All patients were treated with aspirin and ticlopidinc. The follow-up angiograms were obtained at 7±4 months. The overall in-stent restenosis rate was 27.1%. The coronary angiographic findings were 32 single vessel(54.2%), 19 two vessel(32.2%) and 8 three vessel disease(13.6%). The angiographic morphological characteristics were type A in 33(55.9%), type B in 14(23.7%), type C in 12(20. 3%) cases. Variables of 16 patients with restenosis were compared with those of 43 patients without restenosis. Previously known predictors for in-stent restenosis were multiple stenting, stenting for restenotic lesions, residual stenosis after stenting, stenting for total occlusion lesions, reference diameter, balloon to vessel ratio, acute gain and minimal luminal diameter after procedure, design and characteristics of stents, ostial lesion of aorta, high pressure method for stenting, lesion length, diabetes mellitus, size of artheroma, saphenous vein grafts, ulcerlating lesions and calcified lesions. In this study, Reference diameter before stenting(2.43±0.54mm vs. 2.88±0.65mm, p=0.016) and balloon-to-artery ratio(1.28±0.26 vs. 1.11±0.18, p=0.006) were predictors for in-stent restenosis. 1) The overall in-stent restenosis rate was 27.1%. 2) In the analysis of predictors for in-stent restenosis, there was no significant differences in clinical, angiographic factors between group with restenosis and without restenosis. But, Only reference diameter before stenting and balloon-toartery ratio were predictors of late in-stent restenosis. In conclusion, stenting is effective revascularisation method for selected patients with ischemic heart disease, and to minimize in-stent restenosis rate, stent implanting is achieved in a large vessel on the basis of an artery-to-stnet ration of 1:1, if possible.

  이 논문의 목적은 인접 또는 대향하는 국가의 경계선상에 위치한 천연자원을 둘러싼 국가간의 경계획정 및 영유권 분쟁에서 월경천연자원의 개발에 적용될 수 있는 국제법적 원칙을 검토하는데 있다. 왜냐하면, 경계획정문제나 자원이 매장된 지역을 둘러싼 영유권 분쟁을 해결하는데 있어서 천연자원의 개발문제가 가장 큰 역할을 하고 있기 때문이다. 또한, 공동자원개발은 분쟁당사국의 정치적 경제적 이해관계가 맞물린 영유권 분쟁의 해결에 효과적인 방법이 될 수 있다.<BR>  비록 공동개발이 법적 의무는 아니더라도, 분쟁당사국의 자원에 대한 이해관계가 경계획정 또는 영유권 분쟁에 있어 실질적인 역할을 하고 있다. 이것은 분쟁당사국 사이에서 주권적 권리나 관할권 분쟁으로 인해 제로섬 효과로 가는 것을 막고, 협력의 원칙을 동해 분쟁 당사국의 자원에 대한 공통의 이익을 도모할 수 있을 것이다. 이러한 협정에 적용되는 법규의 발달을 검토하고, 현재 국가관행으로 이루어지고 있는 월경단위화협정과 공동개발구역 설정을 위한 공동개발구역 협정을 검토한다. 이 경우 월경천연자원을 공동으로 개발하기 위한 협정에서 천연자원에 대한 국가의 주권은 통합되지 않고, 관계 국가의 영유권 주장은 보류되는 한시적 해결방안이다.   The aim of this study is to evaluate the present and potential significance of the role played by natural resources in boundary and territorial disputes.
