이온 주입이 일함수 차이에 미치는 영향을 연구하기 위하여 낮은 에너지 이온 가속기, 전자총과 기타 일함수 차이를 측정하기 위한 장치를 설계, 제작하였다. 제작된 이온 가속기의 집속 특성은 이론적인 값과 일치하였다. 즉, 집속 렌즈의 확대율이 이론값은 2.0인데 비하여 1.2로 상당히 작은 값이었다. 또한 집속 렌즈의 전압 V_L과 추출 전압 V_e에 의한 집속 특성 역시 이론값과 매우 잘 일치하였다 . 제작된 장치를 사용하여 다결정 Cu와 Ni의 일함수 차이를 측정한 결과 0.45eV임을 알았다. 그리고 전자선을 이용하여 억제 전위차로 일함수를 측정할때 입사 전자의 반사율을 고려해야 함을 알았다. Low energy ion accelerator, electron gun, and apparatus for measuring work function difference are designed and constructed in order to study the effect of ion implantation on the work function. The focusing properties of accelerator is coincided with theoretical results; the magnification of Einzel lens is found to be 1.2, while theoretical value is 2.0, and the focal properties as a function of V_L/V_e are in good agreement with theory. Using these systems, the work function difference between polycrystalline Cu and Ni is found to be 0.45eV, and the experimental retarding potential plots indicate close agreement with the theoretical values modified by electron reflection.

제주도 감귤원 토양에서 GUS, RF, AF 지수를 이용한 농약의 용탈잠재성 평가

오상실,현해남,문두길,정종배 한국환경농학회 2002 한국환경농학회지 Vol.21 No.1

유기물함량이 다른 감귤원 토양을 대상으로 CUS, RF 및 AF값을 비교하여 감귤원에서 많이 사용되고 있는 농약 종류별 지하수 오염 잠재성을 평가하였다. GUS에 의하면 metribuzin과 metolacholr는 조사된 모든 토양등에서 용탈 가능성이 큰 것으로 평가되었으며, alachlor와 lin-uron도 대부분 토양에서 용탈가능성이 높은 것으로 평가되었으며 linuron의 경우에는 특히 비화산회토양에서 용탈의 가능성이 매우 높은 것으로 나타났다. Diuron과 diniconazole은 대부분 토양에서 용탈 가능성이 없는 것으로 평가되었고, chlorothalonil과chlorpyrifos는 유기물 함량에 관계없이 용탈 가능성이 없는 것으로 평가되었다. RF에 의한 평가에서는 diniconazole, chlorothalonil, chlorpy-rifos는 모든 토양에서, linuron과 diuron은 일부 비화산회토를 제외한 모든 토양에서 이동성이 매우 낮은 것으로 분류되었으며,metolachlor와 alachlor는 대부분의 토양에서 이동성이 보통인 것으로, metribuzin은 유기탄소함량이 낮은 토양에서 오염 잠재성이 있는 것으로 평가되었다. AF에 의하면 diniconazole, chlorothalonil, chlorpyrifos는 화산회토, 비화산회토에 관계없이 지하수 오염 잠재성이 없는 것으로 평가되었으며, 반면 metribuzin은 화산회토, 비화산회토에 관계없이 오염 잠재성이 있는 것으로 평가되었다. Metolachlor는 비화산회토에서 지하수 오염 잠재성이 있는 것으로 평가되었고, al-achlor, linuron 및 diuron은 유기물 함량이 낮은 일부 비화산회토에서만 지하수 오염 잠재성이 우려되는 것으로 나타났다. 농약의 용탈잠재성은 용해도, 흡착성, 잔류성 등의 약제 자체의 특성과 함께 유기물 함량, 투수성 등 토양의 물리화학적 특성에 따라서 결정된다. 본 연구의 결과를 보면 이러한 일반적인 원칙이 각 농약의 용탈잠재성 지수에 그대로 반영되었는데, 용해도가 높고, 흡착성이 약하며 잔류성이 긴 약제일수록 대부분의 토양에서 용탈잠재성이 큰 것으로 나타났다. 토양의 특성 중에서는 특히 농약의 흡착에 직접 영향을 미치는 유기물 함량이 용탈잠재성 지수를 결정하는 중요한 요인으로 볼 수 있는데, 본 연구의 결과에서도 일반적으로 유기물 함량이 높은 화산회 토양에서는 농약의 용탈잠재성이 비화산회토양에 비교하여 낮은 것으로 나타났으며, 용해도가 높고 흡착성이 매우 낮은 약제인 metribuzin의 경우에도 투수성이 상대적으로 높은 화산회 토양에서보다 투수성이 낮은 비화산회토양에서 용탈 가능성이 높게 평가된 것으로 보아 대부분 농약의 용탈잠재성을 결정하는데 있어 토양의 투수성보다도 유기물 함량이 더욱 중요하게 영향을 미치는 것으로 판단할 수 있다. 따라서 비화산회토를 위주로 한 유기물 함량이 낮은 토양이 분포된 지역의 지하수가 농약의 오염에 취약할 것으로 판단할 수 있으며, 이들 지역에서는 용탈잠재성이 높은 것으로 평가된 약제들의 사용을 최대한 제한함으로써 제주도 지하수의 농약 오염을 방지할 수 있을 것이다. 물론 제주도 감글원에서는 토양의 유기물 함량과 약제의 흡착성을 우선적으로 고려하여 사용할 농약을 선택해야 할 것으로 보이나, 그 외 약제의 잔류성, 사용량, 사용시기와 함께 기후조건, 토양의 투수성, 토충의 깊이, 지하수 깊이 등의 지역적인 특성들이 농약의 용탈잠재성에 미치는 영향도 더욱 구체적으로 파악되어야 할 것이며 농약의 선택 과정에서도 이러한 특성들이 앞으로 고려되어야 할 것이다. Contamination of groundwater by agrochemicals used in the regional-scale is now a major environmental problem, and this is especially true for Cheju island where virtually all potable water is from groundwater. The objective of this study was to assess leaching potential of eight pesticides in soils of citrus orchards using groundwater ubiquity score (GUS), retardation factor (RF) and attenuation factor (AF). Considering GUS estimated in 30 citrus orchard soils, metribuzin and metolachlor were classified as leacher, alachlor in volcanic ash soils and linuron in non-volcanic soils were classified as leacher, but chlorothalonil and chlorpyrifos were classified as non-leacher. For RF values, metribuzin was classified to be mobile in soils of low organic carbon, metolachlor and alachlor were classified to be moderately immobile in most soils, but linuron, diuron, diniconazole, chlorothalonil and chlorpyrifos were all classified to be very immobile. For AF values, diniconazole, chlorothalonil, and chlorpyrifos were classified to be very unlikely leachable in all of the soils, metribuzin was classified to be likely leachable, and metolahclor, alachlor, linuron and diuron were classified to be leachable only in non-volcanic soils. Although there were some variations in the relative potential of leachability of pesticides estimated with the three different indices, the ranking was essentially determined on the base of the intrinsic properties of the chemicals and environmental properties. Among the eight pesticides, metribuzin, metolachlor, and alachlor, which have high water solubility and low K_(oc) values, have a significant leaching potential especially in non-volcanic ash soils of low organic carbon. But diniconazole, chlorothalonil, and chlorpyrifos, which have low water solubility and high K_(oc) values, were classified to be very immobile in all of the soils. Therefore, to lower the possibility of pesticide contamination of the groundwater in Cheju island, those pesticides which have high water solubility and low K_(oc) values should be used with care in soils of low organic carbon including non-volcanic ash soils.

Objectives : To evaluate the degree of bone mineral density and prevalence rate of osteoporosis according to age and to search the preventive strategy for osteoporosis, the factors that affect on bone density were studied in Physical Characteristics of pre- and postmenopausal women in korea. Methods : The subjects were 961 premenopausal and 1,167 postmenopausal women who have examined in health promotion center of Yeungnam University Hospital in Daegu city from January, 1999 to January, 2001. The test for bone mineral density, biochemical factors, and body composition were done. Results : 1) The prevalence rates of reduced bone mineral density and osteoporosis in premenopausal women were 23.8% and 1.6%, respectively. However, these values were increased to 46.1% and 28.1% in postmenopausal women. 2) The body weight and height were important predictive factors for bone mineral density. The effects of age, body weight, and height on bone mineral density were 39%. The body weight was correlated statistically significantly with bone mineral density in pre- and postmenopausal women. The higher body mass index (BMI), the greater value of bone mineral density was revealed in pre- and postmenopausal women. 3) The correlation between body composition adjusted for body weight and bone mineral density revealed similar pattern between pre- and postmenopausal women. The height, lean body mass, muscle mass, mineral content, and mineral fraction were positively correlated with bone mineral density, however, body fat mass, percent body fat, waist/hip ratio, and BMI were correlated negatively with bone mineral density. 4) There was no direct correlation between cardiovascular risk factor and bone mineral density in this study, however, further study is needed because cardiovascular disease and osteoporosis have common risk factor and the prevention of osteoporosis can help to prevent cardiovascular disease. 5) In multiple regression analysis among bone mineral density as a dependent variable and independent variables (age, body weight, height, Ca/creatinine ratio, and alkaline phosphatase (ALP)), ALP revealed statistically significant inverse correlation with bone mineral density. Conclusions : These results suggested that to prevent osteoporosis, the systemized program including physical condition for promoting anti-osteoporotic factor have to be developed and apply from the thirties whom have maximal bone mineral density.

백영환,김현경,강석태,황정남,이철주,최대선,정병두 연세대학교 자연과학연구소 1985 學術論文集 Vol.15 No.-

낮은 에너지 가속기를 제작하여 순도가 99.99%인 다결정 Ni에 Li^+ 이온을 7 keV의 에너지로 각 시료에 대한 이온주입율이 1.3×10^16atoms/㎠, 4.0×10^15atoms/㎠, 2.0×10^15atoms/㎠, 1.0×10^15atoms/㎠, 2.0×10^14atoms/㎠ 가 되도록 주입시킨 후 전자총과 억제 전위차형 에너지 분석기를 이용하여 일함수의 변화를 측정하였다. 이온 주입율이 2×10^15atoms/㎠보다 작을 때는 일함수가 1.9 eV까지 감소하였고 이온주입율이 4.0×10^15atoms/㎠보다 많을 때는 일함수가 2.8 eV까지 증가하였다. 이것은 Topping의 이론 및 Bauer의 실험결과와 일치함을 보였다. The changes in the work function of polycrystalline Ni with a purity of 99.99% due to Li^+ ions implanted using a low energy ion accelerator and retarding potential energy analyser(RPEA) have been studied. The implantation energy of the Li^+ ions is 7 keV and the implanted ion dose for the various samples are 1.3×10^16 atoms/㎠, 4.0×10^15 atoms/㎠, 2.0×10^15 atoms/㎠, 1.0×10^15 atoms/㎠ and 2.0×10^14 atoms/㎠. When the ion dose is less than 2×10^15 atoms/㎠ the, work function decreases to 1.9 eV, but when the ion dose is more than 4×10^15 atoms/㎠, the work function increses to 2.8 eV. These results are in good agreement with Topping's theory and Bauer's experiment.

Java 병행프로그래밍 도구의 개발

박양수,김현규,문남두,이명준 울산대학교 1999 공학연구논문집 Vol.30 No.2

분산응용시스템은 서비스의 효율향상을 위해 일반적으로 병행성을 지원하는 것이 바람직하다. 그러나 병행성을 지원하기 위한 프로그래밍 기법은 난이도가 높은 구현 기법이며, 대부분의 프로그래밍 언어에서 이를 직접적으로 지원하지 않으므로, 분산응용시스템을 위한 개발자의 부담을 가중시키고 있다. 본 논문에서는 현재 분산응용시스템의 작성에 널리 쓰이고 있는 Java에서 병행성을 체계적으로 지원하기 위한 기반으로서, 세미포어나 조건변수와 같은 고수준 동기화 도구의 개발에 대해 소개하였다. 이러한 Java고수준 동기화 도구는 순수한 Java로 개발되어 이식성을 지니고 있으며, 개발자가 쉽게 기술할 수 있는 인터페이스를 제공하고 있다. 또한 Java가 지닌 대중성으로 인해 대부분의 분산응용시스템의 구축에 널리 사용될 수 있을 것으로 기대된다. In a development of distributed applications, it is desirable for a server to support concurrency in order to provide effective services. However, the programming mechanism for concurrency is difficult to implement correctly, so most programming languages do not support this facility directly. Therefore, the fact imposes extra burdens to the developers for distributed applications. The high-level synchronization tools such as Semaphores and Condition Variables in Java are suggested as a basis for systematically supporting concurrency control. The suggested high-level synchronization tools also have a good portability since it has developed in pure Java. In addition, due to the popularity of Java, these tools will ho a long way with developers in building distributed systems.
