본 연구는 폐비닐 펠렛을 도로포장재료로 재활용하여 자원절약 및 아스팔트 혼합물의 품질향상을 위한 연구이다. 이를 위하여 폐비닐의 첨가량별 배합설계를 수행하여 적정 폐비닐 첨가량과 최적 아스팔트 함량으로 편마암과 화강암 2가지 골재와 폐비닐인 RHDPE의 함량을 4가지로 혼합물을 제작하여 8종류의 재질 혼합물과 2종류의 무개질 혼합물을 제작하였다. 그리고 이 공시체에 대하여 마샬안정도, 간접인장강도 및 Kim test와 반복주행시험 등 실내시험을 통하여 혼합물의 특성을 분석하였다. 폐비닐 첨가량은 RHDPE가 8%일 때 안정도와 간접인장강도 모두 가장 우수한 것으로 나타났고 취성도 나타나지 않았다. RHDPE를 첨가한 혼합물에 대하여 Kim test를 수행한 결과 DR과 DS 모두 높은 상관성을 보였다. 그리고 반복주행시험에서는 RHDPE를 첨가한 혼합물이 일반 혼합물보다 우수하였다. 향후 많은 실험을 통해 RHDPE의 우수성을 입증한다면 소성변형 저항성에 우수한 재료로 이용될 수 있을 것이다. This study is a fundamental research for recycled high-density polyethylene (RHDPE) in asphalt mixture for improving roadway pavement. Marshall mix design was conducted and optimum asphalt content(OAC) was determined for dense-graded surface course mixture by RHDPE content. Marshall stability test, indirect tensile strength (ITS) test, wheel tracking trest and Kim-test were carried out to measure the characteristics of RHDPE-added asphalt concretes. From the results of this study, RHDPE in asphalt mixture if possible. It could be considered that adding too much RHDPE in asphalt mixture is not proper. The optimum content of RHDPE was appeared to be 8%. In Kim-test, statistical analysis was performed for each loading head and aggregate to find out correlation between S_(D) values and each rut parameter. The analysis result showed that S_(D) had very high coefficient of determination with rut parameters on the average.

This study was carried out to test the body fat breakdown during topical seaweed extract treatment and in combination with the aerobic exercise. Of 20 female obesity subjects, ten treated a cream types of seaweed extract(control group) and ten treated a placebo cream(placebo group). Topical treatment of each sample was designed for 4 weeks, and treated with 2 times a day about 10ml on the abdomen and the thigh, respectively. All subjects were participated aerobic dance half hour a day and four times a week. After 4 weeks of topical treatment and exercise, they were measured body fat, skinfold thickness, body circumference. Then venous blood samples were taken and analyzed blood cells, serum enzymes, and serum lipids. There were reduction of body weight, % of body fat, antebrachium, brachium, chest, waist, thigh circumference and abdomen thickness between pre and post treatment in both group. Especially, body weight and % of body fat significantly reduced in the subjects treating the seaweed extract than those treating the placebo. There were significant decrement in total cholesterol and LDL whereas increment in HDL and TBIL in the control group, but no significant difference in the placebo group. In conclusion, there were 7.6% of body fat reduction during 4 weeks of aerobic exercise and 21% of body fat reducement in combination of topical seaweed treatment and exercise, respectively. These results suggest that the topical treatment of seaweed extract should be very effective for fat breakdown. Especially, the body fat breakdown maximized in the combination with the topical seaweed extracts treatment and the aerobic exercise.

The high hardened materials that are remarkable in aspects of durability have been used for die and mold industry. As the high hardened materials are hard to machine, the high-speed machining is essential to manufacture these materials. Currently, in the general turning and milling, experiments to the tool wear monitoring have studied, but those have not applied in high-speed machining. In this study, the cutting mechanism was analysed by the cutting force according to cutting conditions, and the parameters to monitor the tool wear were selected from the tendency of the cutting force and acceleration according to cutting length in the high-speed machining of the high hardened materials(STD11).

In this study, the relationship between substance use and high-novelty seeking was tested using Cloninger et al's 240-items Temperament and Character Inventory(TCI) in 34 substance users(32 methamphetamine and 2 cocaine dependence disorders), 80 normal controls and 48 schizophrenics Demographic characteristics and substance use-related past history were taken by semi-structured interview. Subjects were aged 18-45 and general psychopathology was screened by Symptom Checklist 90 revised. The results were as follows. 1) Among temperament subdivisions in the TCI, novelty seeking(NS) was significantly higher in the substance users(22.1±4.9) than the normal controls(18.0±5.0) and the schizophrenics(15.6±3.3). There were no significant differences in other temperament subdivisions such as harm avoidance, reward dependence and persistence, neither character subdivisions such as self-directiveness, cooperativeness and self- transcendence. 2) A significant inverse correlation was found between NS and age both in the substance users(r=0.274) and the normal controls(r=0.468). This study suggested that the biogenetic temperament characteristics in substance use disorder were related with their high novelty seeking, not low harm avoidance.

For the evaluation of cardiovascular function, aerobic capacity with VO₂max and AT(anaerobic threshold)have been used as a critical parameter. Also we expect that parameter during recovery can be used as a good one. The purpose of this study was to identify the relationship between maximal or submaximal aerobic capacity and the recovery rate of them. We studied with twenty seven subjects: 7 judoists, 10 long distance runners and 10 non-athletes. They were undergone a continuous incremented treadmill test from rest to all-out. Respiratory gas of each subjects was analyzed by using an automated respiratory gas analyzer, Ergo-Oxyscreen System (Erich-Jaeger Co.). As the data of heart rate, oxygen uptake at rest and during recovery made the log linear model with time, the gradient of recovery rate was calculated by the equation of simple regression with the time as independent variable. That equation is as follows; y=A+B.e?? ? y:HR or VO₂ ? A:expected value at rest ? B:maximum increment ? c:recovery rate The results of this study was; 1. There was a significant difference as the order of long distance runners, judoists, non-athletes' HR at rest, but there was no difference in the maximal HR. 2. Long distance runners had higher level of VO₂max(84.83ml/kg) and AT(80.03%) than the other two groups. 3. In the long distance runners group, the phase of VO₂recovery showed significant correlation with the other factors. 4. In judoists group, the phase of VO₂max recovery had significant correlation -0.79(p<0.05) with the maximal HR. 5. In all subjects, significant correlation was showed between AT, HR at rest and recovery of VO₂. In brief, maximal or submaximal aerobic capacity(VO₂max, AT etc.) had no correlation with the phase of HR recovery, but significant correlation with the phase of VO₂recovery in athletes. The results indicated that the recovery rate of oxygen uptake could be a critical index for evaluating the aerobic capacity.

A site plan for 16,110 persons and area of 308,569㎡ was planned by Chonju City. This paper is to study the effects of the site development on Sam-cheon. Average water quality of Sam-cheon was BOD_5 46.0㎎/ℓ in Jan. and Feb., which exceeded the class levels of legislated water quality obviously. If the site were developed by plan, amounts of estimated overall sewage, BOD and SS loads to Sam-cheon would be about 2,954 ㎥/day, 702 ㎏ BOD/day and 409 ㎏SS/day respectively. Even if the sewage of developed area is treated through the legislated purification system, BOD concentration of the stream would be 2.2 ㎎/ℓ more than the present by effluent of purification facilities. Therefore, to prevent more degradation of water quality at least, the pollutional regulation of total emission for the stream could be applied to Sam-cheon with a time-limit.
