  • It has been known that Ki(氣) energy is very effective on many adult diseases. Oriental Medicine has acknowledged Ki as an existing reality and investigated its effects on the body. However, the existence of Ki has not been fully explained. In order to find a conclusive evidence on the existence of Ki, this experiment was done to study the mutual relationship of Ki with a magnetic field and BEP (biological energy projector). The BEP apparatus was irradiated under the magnetic field on rats in the hyperlipidemic induced state. Following criterias were measured in this experiment: weight change, weight of the visceral organs, serum, hepatic lipid peroxide, bleeding time, tissue factor, and etc. The following results were obtained in this study: 1. The weight of rat significantly decreased in the magnetic field treated group and radically reduced in the group treated with both magnetic field and BEP. 2. The weight of liver, heart, and kidney increased in both the magnetic field treated group and magnetic field+BEP group compared to the normal group, but decreased in comparison to the control group. No changes were witnessed in the weight of spleen. 3. Serum and hepatic total cholesterol, total lipid, and lipid peroxide level significantly decreased in both magnetic field treated group and magnetic field+BEP treated group, while lipase activity has increased noticeably. 4. Serum HDL showed a significant increase in both magnetic field treated group and magnetic field+BEP treated group compared to the control group, while LDL and VLDL level decreased significantly. 5. A bleeding time significantly increased in both magnetic field treated group and magnetic field+BEP treated group compared to the control group. A tissue factor value of the lung decreased in the magnetic field treated group and magnetic field+BEP treated groups while increased in the control group. 6. Serum and hepatic lipid peroxide and glutathione level were significantly decreased in the magnetic field treated group and magnetic field+BEP treated group, while hepatic glutathione level was significantly increased compared to the control group. 7. A significant increase was found in the serum hydroxyl radical and SOD activity in the dietary hyperlipidemic rats, and significant decrease was found in the serum lipid peroxide content and superoxidase activity. 8. Hepatic cytosolic enzyme xanthine oxidase and aldehyde oxidase showed a significant decrease in the magnetic field treated group and magnetic field+BEP treated group. Through the above experimental results, one can suggest that the magnetic field with BEP can suppress hyperlipidemia and boost lipid metabolism and restructuring a lipid in liver, which increases the function of liver. To conclude, BEP is considered to show more potent effects under the exposure of magnetic field because magnetic field seems to increase the flow of Ki in the body.

  • In this paper, we derive the relationship between the bit error probability (BEP) of maximum a posteriori (MAP) bit detection and the bit minimum mean square error (MMSE), that is, the BEP is greater than a quarter of the bit USE and less than a half of the bit MMSE. By using this result, the lower and upper bounds of the derivative of the mutual information are derived from the BEP and the lower and upper bounds are easily obtained in the multiple-input multiple-output (MIMO) communication systems with the bit-linear linear-dispersion (BLLD) codes in the Gaussian channel.

  • The InAs thin films were grown on GaAs(100) substrate with $2^{\circ}C$ tilted toward [$0\bar{1}\bar{1}$] with different As beam equivalent pressure (BEP) by using molecular beam epitaxy. Growth temperature and thickness of the InAs thin films were $480^{\circ}C$ and 0.5 ${\mu}m$, respectively. We studied the relation between the As BEP and the properties of InAs thin films. The properties of InAs thin films were observed by reflection high-energy electron diffraction (RHEED), optical microscope, and Hall effect. The growth, monitored by RHEED, was produced through an initial 2D (2-dimensional) nucleation mode which was followed by a period of 3D (3-dimensional) island growth mode. Then, the 2D growth recovered after a few minutes and the streak RHEED pattern remained clear till the end of growth. The crystal quality of InAs thin films is dependent strongly on the As BEP. When the As BEP is $3.6{\times}10^{-6}$ Torr, the InAs thin film has a high electron mobility of 10,952 $cm^2/Vs$ at room temperature.

  • Introduction: Although bleomycin/etoposide/cisplatinum (BEP) chemotherapy is established as the standard treatment for germ cell tumours, it requires significant experience in administration and toxicity management to maintain optimal dose intensity. A retrospective review of 30 patients was conducted at UKMMC to study treatment outcomes. Methods & Materials: Patients with GCTs and treated with at least two cycles of BEP chemotherapy between January 2003 and Oct 2009 were eligible for this study. Patients received 4-6 cycles of bleomycin 30,000IU IV D1, D8 & D15 and either etoposide $100mg/m^2$ IV D1-D5 and cisplatin $20mg/m^2$ IV D1-D5 (5 day BEP regimen) or etoposide $165mg/m^2$ D1-D3 and cisplatin $50mg/m^2$ D1-3 (3 day BEP regimen) every three weeks per cycle. All patients received prophylactic granulocyte colony-stimulating factor (GCSF) from days 6 to 10 of each cycle. The overall response rates, 2 year progression-free survival and overall survival of the whole cohort were assessed. Results: Thirty patients fulfilled the inclusion criteria. Non-seminomatous GCTs comprised 93.3% of cases and gonadal and mediastinal primary sites were the most common. Sixty percent were classified as IGCCCG poor risk disease. Median follow-up was 26.6 months. The overall response rate (CR+PR) was 70%. The two year PFS and OS were 70% and 66%. There was a significant difference in terms of the overall response rate (85% vs 40%, p = 0.03) and in PFS (94.7% vs 50%, p = 0.003) between gonadal and extragonadal primary sites. Conclusion: It is possible to achieve outcomes similar to those in international clinical trials with close monitoring and good supportive care of patients undergoing BEP chemotherapy. There is a strong argument for patients with IGCCCG poor prognosis disease to be treated in specialist tertiary centres to optimize treatment outcomes.

  • In this paper, the performance of generic orthogonal space-time block codes (OSTBCs) introduced by Alamouti [2], Tarokh [3], and Su and Xia [11] is analyzed. We first define one-dimensional component symbol error function (ODSEF) from the exact expression of the pairwise error probability of an OSTBC. Utilizing the ODSEF and the bit error probability (BEP) expression for quadrature amplitude modulation (QAM) introduced by Cho and Yoon [9], the exact closed-form expressions for the BEP of linear OSTBCs with QAM in quasi-static Rayleigh fading channel are derived. We also derive the exact closed-form of the BEP for some OSTBCs which have at least one message symbol transmitted with unequal power via all transmit antennas.

  • We propose a multi-rate and multi-BEP transmission scheme using adaptive overlapping pulse-position modulator (OPPM) and optical power controller in optical code division multiple access (CDMA) networks. The proposed system achieves the multi-rate and multi-BEP transmission by accommodating users with different values of OPPM parameter and transmitted power in the same network. The proposed scheme has advantages that the system is not required to change the code length and number of weight depending on the required bit rate of a user and the difference of bit rates does not have so much effect on the bit error probabilities (BEPs). Moreover, the difference of transmitted powers does not cause the change of bit rate. We analyze the BEPs of the four multimedia service classes corresponding to the com­binations of high/low-rates and low/high-BEPs and show that the proposed scheme can easily achieve distinct differentiation of the service classes with the simple system configuration.

  • The main idea behind the Intelligent Networks(IN) concept is the separation of switching functionality from the service control, in order to meet various service requirements of subscribers and development of new services in time. In (N+1) type Intelligent Network with FEP-BEP framwork, each SCP-BEP system maintains its own subscibers' database respectively. In this case, DB updating operations at each SCP-BEP should be peformed concurrently such that DB updating method could affect the overall system performance. Moreover, it is not easy to predict the current system capacity to satisfy the future IN subscribers' service needs. In this paper, we discuss how much DB updating method affects the performance trends of (N+1) type Intelligent Network with FEP-BEP system by means of the simulation technique as the number of calls increase. The average turnaround time is used as a system performance measure.

  • Using a method recently reported in the literature for analyzing the bit error probability (BEP) performance of noncoherent Mary orthogonal signals with square-law combining in the presence of independent and identically distributed Nakagami-m faded paths, we are able to reformulate this method so as to apply to a generalized fading channel in which the fading in each path need not be identically distributed nor even distributed ac-cording to the same family of distribution. The method leads to exact expressions for the BEP in the form of a finite-range integral whose integrand involves the moment generating function of the combined signal-to-noise ratio and which can therefore be readily evaluated numerically. The mathematical formalism is illustrated by applying the method to some selected numerical examples of interest showing the impact of the multipath intensity profile (MIP) as well as the fading correlation profile (FCP) on the BEP performance of M-ary orthogonal signal over Nakagami-m fading channels. Thses numerical results show that both MIP and FCP induce a non-negligible degradition in the BEP and have therefore to be taken into account for the accurate prediction of the performance of such systems.

  • 지능망은 소비자 또는 가입자의 다양한 욕구를 신속하고도 효과적으로 제공하며 동시에 새로운 서비스에 대한 수요가 있을 경우에 이에 쉽게 대처할 수 있는 차세대 통신망이다. FEP - BEP 구조를 갖는 (N+1) 형식의 지능망 시스템에서는 가입자에 대한 자료(DB)를 각 SCP-BEP 시스템별로 동시에 보유하고 있다. 이러한 자료에 대한 내용의 수정은 모든 BEP 시스템에 대하여 동시에 이루어져야 하며, 자료수정 방법에 따라서 시스템의 성능에 영향을 미친다. 또한, 현재의 시스템이 갖고 있는 미래의 지능망 가입자에 대한 서비스의 최대수용능력을 예측하기란 매우 어렵다. 이 논문에서는 (N+l) 형식의 지능망 시스템이 서비스 호의 증가와 자료수정방식에 따라서 변하는 시스템의 성능추이를 시뮬레이션 기법으로 추적하고 그 결과에 대하여 기술한다.
