Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

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.

Phosphate remaining in wastewater treatment must be removed for the conservation of water quality in a water system. The concentration of phosphate can be decreased from a physic-chemical method for the discharge water of a sewage disposal plant. In this study, it was performed to examine the adsorptive characteristics of sand filter through batch and column experiments in saturated soil. Batch experiment evaluates the concentration change of phosphate with retention time and column experiment performs to analyze a breakthrough curve for phosphate adsorption. And the batch experiment result of adsorptive equilibrium was fitted for the Langmuir model and the Freundlich model. The results obtained from this study were summarized as follows; 1. In the batch experiment, the adsorptive capacity of PO_4^-3 by sand was below 47% of adsorption rate for retention 24 hours in the range of initial concentration 2.0㎎/ℓ ∼4.6㎎/ℓ. 2. The Langmuir and the Freundlich models on the adsorptive equilibrium were fitted well to both in a good correlation coefficient. 3. In the column experiment, the adsorptive breakthrough curve for input PO_4^-3(15.0㎎/ℓ) occurred to about 30ℓ. And output concentration was almost decided at initial breakthrough curve.

Multimedia data are composed of several media data that have their own error characteristics. They have temporal and spatial relations. To support these characteristics, ⅰ) Each media data should be transmitted and managed separately and collectively, ⅱ) Data should be transmitted within a specified time limit, ⅲ) Each media data that exists for the same length in time axis should be transmitted concurrently, ⅳ) Not only temporal relations, but also spatial relations should be transmitted during the data transfer phase, ⅴ) Appropriate error recovery mechanisms should be applied separately according to each media. We have designed a transport protocol which support realtime transmission of multimedia data Our transport protocol is characterized as follows. ⅰ) It supports realtime transmissions f multimedia data that have stream input and stream output. ⅱ) The temporal and spatial relations of multimedia data are transmitted to the receiver using a separate channel. ⅲ) Appropriate error recovery mechanisms are applied separately according to each media. In particular, the transmission methods of spatial and temporal relation is graceful. And the error recovery mechanism is favorable in the multimedia communication

본 연구에서는 이취를 유발하는 조류가 정수공정에 유입되었을 경우, 대표적인 고도종수처리 공정으로 알려진 오존처리공정에서 오존접촉시 pH, 총유기탄소(TOC), 자외부 발현성물질(UV-254) 및 NH4+-N 등의 변화특성을 조사하였다. pH가 초기에 7.4에서 오존접촉 10분까지는 급격한 pH 저하현상을 보인 후에 pH는 서서히 감소하는 현상을 보이며 오존접촉 100분에는 2.1까지 저하되었다. TOC와 UV-254는 오존과의 접촉시간에 따라 지속적으로 감소하는 경향을 나타내었다. NH4+-N와 NO2--N의 농도에 비해 NO3--N은 비교할 수 없을 정도의 높은 농도 차이를 보이고 있다. 오존접촉시간이 길어질수록 전기전도도 값도 높아지는 것을 알 수 있었다. The objectives of this research were to estimate variation characteristics of pH. TOC. UV_254 and NH₄^{+}-N. etc. if odorous generated algaes flowed into water treatment plant and they contacted with ozone known as typical advanced treatment. Initial pH 7.4 did suddenly decline to early l0min. and then pH drop did almost occur. and pH decreased to 2.1 in ozone contact 100min.. TOC and UV-254 continued to decrease with passed time of ozone contact. NO₃^{-}-N cocentration was much higher than NH₄^{+}-N and NO₂^{-}-N for whole test period. Conductivity showed high as passed time of ozone contact.

Whangryunhaedok-Tang (WT) is formulated with Coptidis Rhizoma, Phellodendri Cortex, Scutellariae Radix and Gardeniae Fructus, and Daewhang-whangryunhaedok-Tang (DWT) is made by the combination of Rhei Rhizoma, a wellknown anticostipation drug in WT. Therefore, DWT has been evaluated for antihyperlipidemic effects on experimental hyperlipidemic rats and mice induced by corn oil and high cholesterol-diet. Oral administration of DWT significantly inhibited the increase of serum triglyceride and LDL-cholesterol levels, and the decrease of serum HDL-cholesterol levels in hyperlipidemic rats induced by corn oil. Also, oral administration of DWT significantly prevented the increase of serum total cholesterol, triglyceride and LDL-cholesterol, and liver total cholesterol and triglyceride in 1% cholesterol-diet fed mice. These results suggest that DWT is effective for the treatment of hyperlipidemia.

As a wave of multi-media era comes in, User Interface Design has emerged as a critical concern for Design. It is particular for GUI or Graphic User Interface. The concern for GIR is in great demand for the elders, who are suppose to use the Web and the Internet, for following the trend of our societys aging Accompany with this fact, caber-character for older users that enhances information retrieval and promote efficiency of information search, even further for mutual understanding between information distributors and information seekers, are becoming one of the biggest concerns for most Web designers. It is recommended for cyber-character design by considering GUI for the elders that the design is easy to be perceived through reading, using, and even through entertainment factors of a site where older users are being logged in. It is also important that a cyber-character is possible to perform tasks, just to name a few, as a helper, a counselor, and even an educator sometimes. Cyber-characters intermediate communication when GUI is fabricated throughout the process of character design works. When it is possible and happens, cyber-character take a hub of information transmission in the cyber space.
