Abstract- In a plasma source ion implantation, the target is successively biased by negative voltage pulses with an intrinsic finite rise time, resulting in the time-dependent sheath formation around the target. Measurement of time-dependent sheath during the pulse rise show the ion matrix sheath development which is in proportion to square root of time and pulse rise rate over plasma density but independent of the ion mass.

경기, 강원, 충청, 경상 그리고 전라지역 에서 225마리의 들쥐를 포획하였더니 Apodemus agrarius coreae가 200마리로 전국적인 분포를 보였고, Apodemus peninsulae peninsulae는 25마리로 강원, 경상 및 전라지역에서만 포획되었다. 전기영동법을 이용하여 이들 두 종에 대한 간장 조직에서 조사하였던 G6PDH, ADA, PEP-A, PEP-B, AAT, SOD, LDH, MDH, PNP, GAPDH 등 10종 모두가 검출되었다. 등줄쥐에서는 전기영동분석 결과 32종의 표현형이, 흰넓적다리붉은쥐에서 8가지가 검출되었다. 두 종의 locus의 평균 유전학적인 다양성은 0.130으로 나타났고, 유전학적인 차이는 0.100~0.600으로 상대적인 차이를 보였으며, 등줄쥐는 0.150~0.398사이에 네 개의 집단으로 구분되었던 반면 흰넓적다리붉은쥐는 0.100~0.275의 차이로 확인되었다. 경기지역의 안성, 여주 그리고 전라지역의 완주에서 포획된 등줄쥐를 제외하고는 지역에 따라서 6~11개의 조직내 효소 표현형이 중복되어 있었다. 흰넓적다리붉은쥐 역시 한 가지 이상의 표현형이 있었고 이들은 지역적인 차이를 보였으며, 등줄쥐와 조직내 효소형과 중복되어 있었다. Two hundred of Apodemus agarius coreae and twenty five of Apodemus peninsulae peninsulae were caught from Kyonggi, Kangwon, Chungchong, Jeolla and Kyongssang provinces across the country. Isoenzyme patterns were analyzed by gel electrophoresis with liver homogenates of A. a. coreae and A. p. peninsulae. Using 10 enzyme systems, 32 electrophoretic types (ETs) were identified from two species of Apodemus including 8 ETs from A. p. peninsulae with genetic diversity per locus between 0.00 and 0.54 (mean 0.13). Genetic distances among ETs of A. a. coreae and A. p. peninsulae was between 0.100 and 0.600. Thirty two ETs of both species of Apodemus were classified to four major groups with genetic distance from 0.150 to 0.398. Eight ETs of A. p. peninsulae were grouped into four subgroups with genetic distance from 0.100 to 0.275. All ETs of A. p. peninsulae were belong to those of A. a. coreae with enzymatic variation. There was only one ET in A. a. coreae from Ansong an Yoju counties in Kyonggi and Wanju county in Jeolla province. However, all samples collected from the rest were identified to have 6 to 11 ETs on local enzymatic variance. Enzymatic overlap between both species was confirmed with at least one ET depending on the sites of collection.

The purpose of this research is to analyze relationships among the habitual life, stress, and constipation and to help prevent and improve the constipation among women's university students. This is a descriptive interrelated research that has targeted women's university students. The data had been collected for 10 days, from December 22, 2003 to December 31, 2003. The survey was carried out to the 295 women's university students that had been randomly selected by visiting four-year-course colleges and universities in Seoul. The survey consists of 78 questions: five questions on the general trait, 11 questions on the habitual life, 51 questions on the stress, and 11 questions on the constipation. There are seven questions on the dietary life, four questions on exercising, and Shin Jung Ran's survey(2003) and Lee Ji Jung's survey(2001) was used as a reference. Yoon Ho Yul's five grade stress barometer(1996) was also used to measure the amount of stress. The collected data was analyzed by a real number, percentage, the arithmetical mean, the standard deviation, t-test, x²test using SPSS 10.00 for Windows Program. Results are as follow 1. Four to six cups of daily water intake was the highest by 50.0%. Students not have breakfast(55.7%) mostly because they did not have enough time(62.6%). Dinner was the most overeated meal by 72.3% and the most preferred food was meat by 42.0%. In the questions related to exercising, more than half of the students answered that they hardly do not exercise(58%), work out for less than 30minutes(67.3%), and exercised lightly(75.3%). 2. Students were suffering from stresses due to the personal relations(51.36±14.0426), scholastic achievement and personal direction(24.93±8.3037), financial conditions and family matters(20.28±8.1718) and social circumstances(2.7262). 3. In the defection part, the student's reply that they have more than five times of bowel movement on a weekly basis(48.3%), and that it takes three to five minutes to defecate(41.3%) were the highest. More than half of the students answered that their one time excrement quantity was between 30 grams to 60 grams(72.3%) and that it was normal(68.7%). In a question asking how it feels after the defecation(students were allowed to choose more than one answer), relieved and refreshed was the highest by 66.6%, an uncomfortable followed by 42.8%. 4.4% of the students answered that they suffer from strong abdominal pain during the defecation. The rest of the students answered that they do not have stomachache or that it was normal. The students were classified into the constipation group of 103 people(34.9%) and the normal group of 192 people(65.1%) under the devised definition of this research. 4. Students that live in dormitories and do their own cooking were more likely to have constipation than those that live in private residence or in a lodgins. 5. The research showed that there is a mutual relation between water in a day intake and the constipation. It means that the lesser water students drink, the more they suffer from the constipation. The number of times a student had a meal everyday and the constipation was interrelated. If a student had lesser or irregular meals in a day, they had more constipation. Preferred food and constipation was also interrelated. Students that preferred vegetable, fruit, and dairy products were more likely to belong in a normal/general group. 6. By dividing the stress factors into the lower categories, we were able to see that the total stress(t-2.063, p-0.040), personal relations(t-2.316, p-0.021), scholastic achievements and personal directions(t-20127, p-0.034) had mutual relation with the constipation. The constipation group(120.27±30.2708) was suffering from stronger level of stress than the normal group(112.97±28.1466). Through this study, we were able to verify that the few general traits, habitual life, and stress of the women's university students have mutual relations with the constipation.

Fineness Modulus is a term used as an index to the fineness of sand. It is well - known that the modulus distribution of sand plays an important role in achieving the desired properties of mortar. The maximum size of sand is also important parameter in mortar. These parameters affect workability, strength and unitweight of mortar. In tills study, different sand gradings were used to investigate effects of fineness moduli of sand for examination about the workability, strength and unit weight characteristics of cement mortar. Two kinds of sands with various size distribution and three kinds of fine aggregates with the similar particle size distribution (Sieve No.16~30, No.30~50, No.50~100) were used. Water-cement ratio (W/C) of mortar mix was kept constant for all the trial mixes with sand of different fineness modulus. Major findings of tills study are: (a) Fine sand with the similar size distribution reduces the workability and unit weight of cement mortar. (b) The compressive strength of mortar is not sensitive to sand grading variations. (c) The compressive strengths at the age of 28 days range from 32.1 to 54.1 MPa. (d) The sand with standard modulus distribution has better positive effects on the properties of the mortar.

Studies on the seasonal distribution of zooplankton were carried out in 1994 in waters off Yongkwang Atomic Power Plant. Zooplankton samples were collected four times seasonally at six selected stations. Forty - three taxa of zooplankton were distributed and 25 species representing 21 copepods, 2 chaetognaths, 1 protozoan and appendicularian were identified to species level. Zooplankton abundance varied between 840-42, 014 indiv. m-3 and were recorded the highest abundance in September and the lowest in February. Seasonal succession in the dominant species was observed from winter and spring with Acartia omorii to summer and autumn with A. pacifica and Paracalanus indicus. With the prevalence of ueritic copepods all the year round, i.e., A. omorii, A. pacifica and P. indicus, the studied waters were revealed to have the typical zooplankton fauna in coastal waters of the Yellow Sea.

This study is done to propose more stable of road landfill based on analysis of seepage and slope stability. To conduct of this study 10 regions that were the most terribly damaged out of collapsed road landfills in Chung-Nam area for 5 years from 1995 to 1999 are investigated at site and tested in laboratory. It is picked up a section of 10 collapsed road landfill and carried out analysis of seepage and slope stability during rainfall. The results of this study is summarized as follows. It is difficult to find out the characteristics that could be any cause of collapse from the results of general rests of soil and the method of construction landfill. It is founded that the road landfill is collapsed because saturation region is increased due to long time rainfall, and the time of saturation is depended on initial water content of landfill. The number of slope stability before rainfall is kept at 1.6, but as saturation area is increased due to infiltration of rain, the number of slope stability is lowered under 1. In this case, the process time is influenced initial water content. In case of road landfill in which side waterway prevented infiltration is not installed, a drain filter located on original ground which made by high permeable materials could be good action, and the road landfill is kept stable.
