Asynchronous Transfer Mode(ATM) has been proposed as the target switching and multi-plexing schemes for broadband ISDN(B-ISDN). A variety of traffic types such as voice, data and video can be integrated into the network. Among the traffic types, video requires a significantly higher bandwidth than voice and data. Since video will be a major traffic component in the future multimedia communiation, transporting video traffic in a very efficient manner will be the key point for the successful implementation of B-ISDN. Therefore, the characterization of video traffic sources are essential for the design of traffic control algorithms in ATM networks. The knowledge of bit rate statistics are necessary for the proper bandwidth allocation algorithms in the ATM networks. Since VBR(Variable Bit Rate) video transmission can be achieved taking advantages of the inherent burstiness of video sources, VBR encoding algorithms are well suited for the ATM networks. VBR video transmission also provides uniform quality video by transmitting at a higher rate during high-activity scenes and at a low rate when there is less motion. As the bit rate is not a constant, it is necessary to develop some statistical models in order to represent cell arrivals from video sources. The bit rate generated by a VBR coder depends on the type of video scenes, video coding algorithms, and video quality requirements. A video source model should have simple and effective parameters for performance evaluation and traffic control of ATM networks. In this paper, some video models are surveyed and reviewed. A video model was chosen and simulated. The simulation results are shown in order to illustrate some generated bit pattern of video sequence. Some of the results found may also be used for the design of efficient traffic control algorithm in ATM networks.

The purpose of this research was to investigate the regulative action of water extract of Salviae miltiorrhizae Radix(SE) on thymocyte and macrophage in mice. The proliferation in thymocyte was tested using a colorimetric tetrazolium assay(MTT assay), The apoptosis and subpopulation in thymocyte were tested using a flow cytometry. Nitric oxide(No) production from mouse peritoneal macrophage was tested using a Griess reagents and the phagocytic activity was tested using a lucigenin chemiluminescence. SE did not affect the proliferation, apoptosis and subpopulation(CD4^+/CD8^+) in thymocyte in vivo, but enhanced the proliferation in thymocyte in vitro. The n-BuOH fraction and water fraction of SE suppressed the nitric oxide production and results suggest the SE does not affect the activity of thymocyte, but suppressed the activity of macrophage.

전립선비대증은 노인 남성에서 흔히 유발되는 질환이며, 노화가 진행될 수록 빈도가 높아지는 특징을 가진다. 이 질환의 원인은 전립선기질세표의 과도한 증식으로 유발된다고 알려져 있지만 그 자세한 기전에 대해서는 잘 알려져 있지 않다. 전립선비대증에서 progesterone 수용체 양성 세포가 다른 전립선 종양에 비해서 많고, progesterone은 testosterone에서 DHT로 전환되는 것을 감소시키는 역할을 가진다고 알려졋다. 또한 남성 전립선 평활근의 과증식에 의한 질환이므로 평활근 세포의 증식과 관련성이 있다고 보고된 COX-2의 전립선비대증에 대한 영향에 대한 연구가 필요하다. 전립선 기질세포에 progesterone을 3일간 투여하여 배양한 경우 기질세포 증식은 차이가 없었다. Progesterone을 단독 또는 DHT와 같이 투여한 기질세포에서 남성호르몬 수용체 mRNA 발현은 비처리군과 비교하여 유의한 차이가 없었다. 또한 progesterone과 DHT 동시 투여에 의한 COX-2 mRNA 발현에도 차이가 없었다. 그러나 progesterone에 의한 남성 호르몬 수용체와 COX-2 단백 발현에서는 대조군과 비교하여 유의하게 감소시켰다. 이상의 결과는 progesterone은 남성호르몬 수용체에 대해 전사 후 반응 (post-transcriptional response)에 효과를 나타내어 남성호르몬 수용체 발현을 감소시키는 작용은 가지며, COX-2 발현 억제효과를 나타내므로 전립선비대증의 치료에 이용될 수 있을 것으로 사료된다. Background: Benign prostatic hyperplasia (BPH) is the most common benign tumor in older men; the etiology of this disease remains poorly understood. Testosterone and dihydrotestosterone (DHT) both act as androgen via a single androgen receptor. Testosterone is converted to DHT by 5α-reductase in prostatic stromal cells. Progesterone has been reported to inhibit DHT conversion; howevwe, its effect on prostatic stromal cells remains to be elucidated. Materials and Methods: In this experiment, we investigated the effect of progesterone on androgen receptor expression induced by DHT. We also tested the effect of progesterone on cyclooxygenase-2 (COX-2) expression, as well as prostate stromal cell proliferation using the cell count kit-8. Results: Progesterone did not cause an increase of prostate stromal cell proliferation. The mRNA expression of the androgen receptor and COX-2 were not changed by progesterone; the expressions of androgen receptor and COX-2 proteins were decreased by progesterone in prostate stromal cells. Conclusion: These results suggest that in prostate stromal cells, progesterone decreases androgen receptor protein expression, which results in decrement of COX-2 protein expression. This effect might be mediated by post-transcriptional regulation.

Non-Hodgkin's 림프종의 약 40%는 결절외(extranodal) 림프종으로 대개 위장관에서 발생하며 이들 중 점막 연관 림프조직(mucosa-associated lymphoid tissue: MALT)에서 기원한 림프종은 MALT 림프종으로 분류된다. 위 외의 부위에서 원발성으로 발생하는 MALT 림프종은 매우 드물지만 실제 거의 모든 신체 장기에 발생하는 것으로 알려져 있는데, 가장 흔한 부위인 위 외에도 폐, 갑상선, 침샘, 눈물샘에 발생하고, 드물게 안구, 유방, 방광, 신장, 흉선 등에도 보고된 바 있다. MALT 림프종은 오랜 기간동안 원격 전이하지 않고 국소 병변으로 남아 있는 특징이 있어 치료 방향 또한 국소 병변의 치료에 집중되며, 예후도 림프절 기원의 림프종에 비해 양호한 것으로 알려져 있다. 본 저자 등은 자궁 내막에 원발성으로 발생한 MALT 림프종 1예를 경험하였기에 문헌 고찰과 함께 이를 보고하고자 한다. Mucosa associated lymphoid tissue (MALT) lymphoma can rarely develop primarily in extranodal sites other than stomach which is the most common site for it. Other rare primary sites are small intestine, colorectum, esophagus, lung, thyroid, salivary gland, lacrymal gland, breast and skin. MALT lymphoma represents a distinct clinicopathologic features: it is usually localized to their original site for a long time and shows much more favorable prognosis than lymphoma at other site, but some MALT lymphoma can arise simultaneously or successively in different organ or give rise to another MALT lymphoma of other organ and can be multifocally disseminated or recurred. We report a very rare case of high grade B-cell lymphoma of mucosa associated lymphoid tissue (MALT) of the uterine endometrium, which was confirmed by immunohistochemical assay.

The purpose of this study is to examine antimicrobial activity, fastness of the washing relating to three bacterial strains such as Chaetomium globosum, Trichophyton mentagrophyte and Staphylococcus aureus, and optimal processing conditions according to the sticking quantity of ammonium salt to antimicrobially finished fabric, when reacting the organic silicone quarternary ammonium salt to cotton fabrics in accordance with the change in concentration, temperature, and time. The result of this study is summarized as follows. 1. It was shown that the growth of Chaetomium globosum in untreated fabric is more rapid about six times than that of Trichophyton mentagrophytes on the seventh day, while the organicsilicone quaternary ammonium salt has more excellent antimicrobial activity of Chaetomium globosum than of Trichophyton mentagrophytes when antimicrobially finishing the cotton fabric by means of the organic silicone quaternary ammonium salt because the growth of Chaetomium globosum was restrained more than Trichophytom mentagrophytes. 2. The condition retaining the greatest effect on antimicrobial activuty was con centration. Then it was shown that Staphylococcus aureus has excellent antimicrobial activity by indicating 96% bacterial reduction at 1.0% concentration, while Chaetomium globosum showed its growth restraint more than 92% at 3.0% concentration. Also Trichophyton mentagrophytes showed its growth restraint less than 71%. 3. It was also shown that reaction degree of ammonium salt to the cotton fabric increase with increase of its concentration. But its degree was lower than that of increase in concentration. 4. Chaetomium globosum showed that formation of its spore is remarkably late at the concentration more than 0.5 % during antimicrobial finishing, under the condition of liquor ratio of 30:1, temperature of 30℃, and time of 30 minutes. 5. The reaction of individual specimens to the organic silicone quaternary ammonium salt according to finishing condition was most high at higher concentration under the conditions of temperature of 40℃, and time of 30 minutes. 6. When washing the antimicrobially finshed cotton fabric five, ten, and twenty times, respectively three strains showed nearly similar antimicrobial activity to the finshed fabric. This fact means that its durability to the washing is very excellent.

The purpose of this study was to examine the relationship between utilization satisfaction with day-care center of the elderly and their life satisfaction. The subjects were 94 older adults who were participants in one of seven day-care centers for the elderly around Seoul and who were over the age of 65 (34 older men and 60 older women). A 18-item composite index, modifying Seo's (2000) Assessment Index for the Elderly Welfare Facility, was used to measure the satisfaction with elderly day-care center. Life satisfaction of the elderly was assessed using Yoon's Criterion of Older Adult's Life Satisfaction. Data were analyzed with t-test, analysis of variance and Pearsons' correlation. The major results were as follows: First, most respondents used the center for more than two years, and they visited the center 3-4 times per week. Most of the elderly used the center for health recovery and they recognized that their health improved after using the facility. Medical treatments and physical body service programs were preferred among programs operating in the facility. Second, utilization satisfaction was found to be relatively high. The satisfaction with the elderly day-care center varied with older adults' subjective view on their health condition, monthly allowance, religions, and age. The motive to use the facility was also found to be associated with the level of satisfaction. Voluntary participants reported higher level of satisfaction than non-voluntary participants. Third, there was positive association between utilization satisfaction and life satisfaction. Life satisfaction of the elderly who use day-care center was relatively high.
