Objectives: This study is a practice based research conducted to investigate the effectiveness and safety of a 5-day short-term diet program ('Oil-rescue' program) designed to reduce the adverse events and initial dropout rate in obesity treatment. Methods: We retrospectively analyzed 4 Korean medicine clinic patient data who completed 'Oil-rescue' program which is consisting of Gambi-hwan, Bium-hwan, Butgiban-hwan and Jayoon Kyungokgo. The weight change before and after participating 'Oil-rescue' program was primary outcome of our study. Changes in body mass index, body fat mass, skeletal muscle mass, body water content, lean body mass, protein, and minerals were also measured. Results: A total of 35 patients who satisfied the eligible criteria were finally included. The body weight decreased from 69.45±11.86 kg to 67.43±11.58 kg, a total of 2.02±1.03 kg (P<0.001). Body fat mass decreased from 25.77±7.45 kg to 24.98±7.26 kg, a total of 0.78±1.21 kg (P<0.001). Body mass index decreased from 26.39±3.64 kg/㎡ to 25.64±3.49 kg/㎡, a total of 0.75±0.41 kg/㎡. (P<0.001). A total of 15 patients had side effects such as diarrhea, abdominal pain, and insomnia, but all were mild. 16 out of 35 people switched to long-term obesity treatment programs. Conclusions: Through this retrospective practice based research, it was found that the 'Oil-rescue' program effectively reduced body weight, body fat, and body mass index, and the other obesity related parameters. It was a relatively safe and effective short-term obesity treatment program.

中學校 確率計算學習에서 視覺化活動의 效果에 對한 硏究

권병조 한국학교수학회 1999 韓國學校數學會論文集 Vol.2 No.1

Two (second-grade) classes of Yu-song middle school were chosen to research the effect of the visualization in the learning of probability calculation at a middle school. One class, as an experiment class, was taught the probability calculation of probability unit by the visualization learning and the other, as a controlled class, was taught it by the traditional lecture, and then through the writing tests there was a verification on the effect of right after test and the delaying test after 3 weeks to examine the learning effect of high- and low-level groups. It was difficult for the students to visualize the problems of the probability calculation, but I suggested simple models to the students and helped them to learn meaningfully. As a result of this study, there showed statistically significant difference in high-level group in the right after test.(P< .05) In the delaying test after 3 weeks, there also showed statistically significant marks only in high-level group.(P< .05) The visualization in the learning of probability calculation took more affirmative effect in the experiment class than the comparative class only in high-level group. The students in low-level group has difficulties in the visualization activities, but all the students in high-and low-level group thought the visualization was a great help to them in learning probability calculation.

방광암에 특이한 Ribonuclease와 단백의 분리와 특징에 대한 연구

권병조,고재경,김동한 한양대학교 의과대학 1990 한양의대 학술지 Vol.10 No.1

Proteins and ribonuclease (RNase) were separated and fractionated by DEAE-cellulose column chromatography, high performance liquid chromatography (HPLC) and polyacrylamide gel electrophoresis (PAGE) to investigate proteins and RNases specific to bladder cancer. The properties of RNase specific to the bladder cancer were studied using homopolyribonucleotides and heteropolynucleotides as substrates. (1) The protein was significantly increased by 16% and the activity of RNase was unchanged in bladder cancer tissues. (2) Proteins in teh bladder cancer tissue were separated by a DEAE-cellulose column chromatography by 7 peaks, of which 3 peaks exhibited RNase activity and 3 other non-RNase protein peaks appeared to be specific to the bladder cancer. Two protein peaks (one RNase peak and one non-RNase protein peak) normally present disappeared in the bladder cancer tissues. (3) DEAE-cellulose protein peaks IV, V and VI isolated fromthe bladder cancer tissue were further separated by HPLC into 5 to 6 subpeaks each, of which two of non-RNase protein subpeaks appeared to be specific to the bladder cancer. One of RNase subpeak normally present disappeared in the bladder cancer tissues. (4) Analyses of DEAE-cellulose protein peaks IV, V and VI from the bladder cancer tissue by native and SDS PAGE revealed that cancer specific proteins were present in multiple in the bladder cancer tissue and that several protein bands present in the control bladder tissues disappeared in the bladder cancer tissues. Results obtained in the present study indicated that RNases were present in the bladder cancer tissue in multiple as isozyme form, that RNases and non-RNase proteins specific to the bladder cancer appeared and that serveral RNase and non-RNase proteins present in the control tissue disappeared, activated or suppressed in th bladder cancer tissues. It could be suggested that changes in separation pattern of RNase an non-RNase proteins in the bladder cancer tissue were much more useful for understanding the nature of the cancer than changes in total protein contents and total activity of RNase.

원주지역 남은 음식물의 계절별 성분 함량 및 비육돈에 대한 건조 남은 음식물 급여 효과

본 연구는 남은 음식물(FW)의 성분변이를 조사하고, 그것이 급여시 비육돈의 성장과 육질에 미치는 영향을 조사하기 위하여 실시하였다. 사료화를 위해 기초자료로 활용하고져 FW를 1년간 (월 6회) 수집하였다. 8주간의 사양시험을 위해 삼원교잡종(LxYxD) 비육돈 (54.80±4.60㎏) 117두를 공시하였다 (3처리 3반복, 반복당 13두). 처리는 대조구 (옥수수-대두박 위주사료), 건조 방법에 따른 단순 건조 (simple dry : SD) 및 진공발효 (vacuum fermentation: VF)로서 구분하였다. FW의 건물기준으로 에너지, 조단백질, 조지방, 화분, 칼슘 및 인의 4계절 평균치는 각각 5,11kcal/㎏, 22.92%, 14.31%, 15.48%, 2.7% 및 1.05%였다. 에너지와 단백질 함량은 각각 겨울과 여름에 가장 높았다 (p<0.05). 건조한 FW의 유산균 함량은 SD와 VF 처리간에 차이가 없었다. 사양성적에서는 ADG에서 대조구가 FW이 첨가된 사료에 비해 유의적으로 높았으나 (p<0.05), FCR에서는 처리간에 차이가 없었다. SD와 FD와의 생산성 비교에서는 유의차가 인정되지 않았다. 지육율, 등지방두께, 그리고 기타육질(색깔, drip loss 및 TBARS)에서 처리간에 차이가 없었다. 전 시험기간의 증체 ㎏당 사료비를 살펴보면, FW가 포함된 사료급여군이 대조구에 비해 낮았다. 이상의 결과를 요약해 보면, 남은 음식물을 건조한 후 사료에 20% 이내를 첨가하여 펠렛사료로 급여할 경우 비육돈의 사료비를 절감할 수 있을 것으로 사료된다. 그러나 FW의 가공시 FD공정은 필요치 않을 것으로 사료된다. A study was conducted to evaluate seasonal variations in chemical composition of food waste (FW) and its feeding effects on growth performance and pork quality in finishing pigs. FW was collected for 1 year ( 6 times a month ) to establish a database for use of FW as a feed ingredient. For a feeding trial (8 weeks), a total of 117 pigs (L×Y×D; 54.80±4.60㎏) were used to evaluate the processing effects of FW. Treatments were: Control (a corn-soybean meal diet without FW), simple dried FW (SD) and vacuum fermented FW (VF). The gross energy, crude protein, crude fat, ash, calcium and phosphorus in FW (DM, average of 4 seasons) were 5,111㎉/㎏, 22.92%, 14.31%, 15.48%, 2.7% and 1.05%, respectively. Among seasons, the energy and crude protein contents were the highest (p<0.05) in winter and summer, respectively. In lactic acid bacterial counts, there was no difference between SD and VF. Pigs fed the control diet grew faster (p<0.05) than those fed diets containing food waster, but not feed conversion ratio. There were no differences in production traits between SD and VF. No differences were also found in dressing percentage, backfat thickness, and pork quality (color, drip loss and TBARS) among treatments. The feed cost (￦/㎏ body weight) was lower in pigs fed FW than those fed a control diet. In conclusion, a pelleted diet containing food waste less than 20% would reduce feed cost in finishing pigs. However, it seems that a vacuum fermentation of food waste is not necessary for diet processing.

주기적 정상상태 대류 열전달 현상의 수치해석을 통한 교류 방식 열선 유속측정법 특성분석

Recently a novel flow measurement technique, a tunable AC thermal anemometry, was proposed and experimentally demonstrated. The technique measures the flow speed by using the phase lag of the temperature oscillation induced by the periodic heat generation imposed on the hotwire. In this study, nondimensional governing equations for the steady periodic heat transfer phenomenon from a hotwire with internal periodic heat generation to the surrounding flow are derived and solved numerically to find the dominant parameters affecting the measurement accuracy of the technique. The results show the phase lag of the sensor is determined by flow speed, thermal diffusivity of the fluid and heating frequency. The measurement sensitivity can be improved by modulating the heating frequency. This anemometry can resolve flow speed as low as 0.07 ㎜/s at 0.1 ㎐ when R22 is the working fluid.
