  • Objectives : The purpose of this study is to compare the principles between moxibustion and the 'Intense pulsed light (IPL)' and to investigate the clinical application of the photo-moxa for the Korean medicine fields. Methods : The characteristics of moxibustion, IPL, parabolic reflector moxa and the dermatology surgical use of moxibustion were reviewed in the literature. Results : IPL is one type of light treatments that is employed by radiating the short-pulse wave, which is transformed from the light of high intensity. There has been used parabolic reflector in Asia for more than 2,000 years, and this hand-held device used for moxibustion in traditional medicine. Moxibustion is one of the treatment tools in Korean medicine using the heat energy. The fluence or energy density of IPL in clinical circumstances is similar to parabolic reflector moxa of moxibustion. IPL and parabolic reflector moxa shared same treatment principle employing the heat energy. Therefore IPL could apply for many indications in Korean medicine as a moxibustion tool and acupuncture. Conclusions: IPL may be plausible to be a fascinate method in phototherapy of Korean medicine.

  • Intensive pulsed light (IPL) technique enables energy to be transferred to a target substance in a short time per millisecond at room temperature under an ambient atmosphere. Due to the growing interest in flashlights with excellent functionality among various technologies, light-sintering research on metal particles using IPL has been carried out representatively. Recently, examples of the application of IPL to various material synthesis have been reported. In the present article, various strategies using IPL including the manufacture of flexible electrodes and the synthesis of metal-organic frameworks were discussed. In particular, the process of improving oxidation resistance and electrical conductivity of electrodes, and also the metal-organic framework synthesis from metal surface were explained in detail. We envision that the review article can be of great help to researchers who investigate electrode manufacturing and material synthesis using IPL.

  • The objective of this study was to investigate the feasibility of applying the Intense Pulsed Light (IPL) as a tool to enhance the skin absorption of arbutin, a well-known skin-whitening agent. Arbutin solution or skin formulation was applied on the back of hairless mouse skin in vivo after IPL treatment, and then the skin deposition of arbutin was determined by HPLC. IPL treatment significantly increased the amount of arbutin in the skin after 6 hours when arbutin solution was applied 20 times. IPL also enhanced the skin deposition of arbutin when arbutin formulation was applied, although it was not significantly different. Significant increase of surface skin temperature was observed by IPL treatment, which might be a mechanism of the enhanced skin absorption of arbutin. These results suggest the feasibility of using IPL as a tool to increase the skin absorption of whitening agents, although further research needs to be conducted to understand its exact mechanism.

  • 최근 낸드 플래시 메모리가 차세대 저장장치로 부상하면서 수십 년간 DBMS의 저장장치였던 하드디스크의 대안으로 주목 받고 있다. 낸드 플래시 메모리는 하드 디스크와 인터페이스가 다르기 때문에 일반적으로 플래시 변환 계층을 사용하여 기존 소프트웨어와 호환성을 유지한다. 하지만 플래시 변환 계층은 소량의 랜덤 쓰기가 빈번한 DBMS 환경에서 비효율적인 방식이다. 이러한 문제점을 극복하기 위해 DBMS의 특성을 고려한 In-Page Logging(IPL) 기법이 제안되었다. IPL 기법은 우수한 성능과 복구의 용이성 외에도 DBMS 구조를 크게 변경하지 않고 구현이 가능한 것이 장점이다. 본 논문의 목적은 IPL 기법을 활용하여 상용 DBMS에서 최소한의 변화만으로 낸드 플래시 메모리를 저장 장치로 사용 할 수 있음을 증명하는 것이다. 이를 위해 Berkeley DBMS에 IPL 기법을 구현하며 성능 평가를 통해 IPL 기법이 상용 DBMS 에서도 우수한 성능을 보이는 것을 확인한다.

  • In this paper, We investigated the effect of heat treatment process using photo-thermal effect in order to improve mechanical properties of nanostructure on polymer films made by nanoimprint process with hybrid resin. Nanostructures which have a low refractive characteristic were fabricated by UV nanoimprint and after that heat treatment was performed using IPL (intense pulsed light) under process condition of 550 V voltage, pulse width 5 ms, frequency 0.5 Hz. The transmittance and mechanical property of fabricated nanostructure films were evaluated to observe changes in the pattern transfer rate and mechanical properties of nanostructures. The transmittance of the nanostructure was measured at 97.6% at 550 nm wavelength. Nanoindentation was performed to identify improved anti-scatch properties. Result was compared by the heat source. In case of post treatment with IPL, hardness was 0.51 GPa and in the case of hotplate was 0.27 GPa, resulting the increase of hardness of 1.8 times. Elastic modulus of IPL treated sample was 5.9GPa and Hotplate treated one was 4GPa, showing the 1.4 time increase.

  • We are faced with a paradox in the age of information as finding quality information on the Internet becomes a more challenging task because of information overload. This paper describes the prototype for “IPL-Korea” (Internet Public Library in Korea) project which is an attempt to provide the public with quality information in the form of a metadata system. The system involves cataloging of resources, i.e. websites, that are filtered by library and information science majors as well as information professionals. The user focus of this system is on children, youth, women, and seniors; various classification schemes and resource descriptions relevant for each user group are incorporated into the system to allow efficient browsing of the resources. A thesaurus for “IPL-Korea”, which is based on the ERIC thesaurus, is being constructed for easy manipulation of the breath of searching. The “IPL-Korea” metadata system employs the entity-relationship model in the design of its conceptual schema. Metadata is being stored in the Oracle database system and Web interfaces to this database are provided through ASP, ColdFusion, and JAVA technology.

  • This study was performed 10 develop the accelerated life test method using Weibull-IPL(Inverse Power Law) model for mechanical components. Weibull-IPL model is concerned with determining the assurance life with confidence level and the accelerated life test time From the relation of weibull distribution factors and confidence limit, the testing times on the no number of failure acceptance criteria arc determined. The mechanical components generally represent wear and fatigue characteristics as a failure mode. IPL based on the cumulative damage theory is applied effectively the mechanical components to reduce the testing time and to achieve the accelerating test conditions. As the actual application example, accelerated life test method of agricultural tractor transmission was described. Life distribution of agricultural tractor transmission was supposed to follow Weibull distribution and life test time was calculated under the conditions of average life (MTBF) 3,000 hours and 90% confidence level for one test sample. According to IPL, because test time call be shorten in case increase test load test time could be reduced by 482 hours when we put the load 1.1 times of rated load than 0.73 times of rated load that is equivalent load calculated by load spectrum of the agricultural tractor. This time, acceleration coefficient was 11.7.

  • Intense pulsed light(IPL) has been highlighted as an innovative nonthermal sterilization technology that can kill spoilage or pathogenic microorganisms by using short-duration pulses of intense broad-spectrum electromagnetic radiation. This paper examines the inactivation effects of IPL on Listeria monocytogenes, Escherichia coli O157:H7, and Pseudomonas aeruginosa inoculated on seafood products such as salmon, flatfish, and shrimps and evaluates the possibility of extending the shelf-life of seafood products. The results indicate that the inactivation of microorganisms increased with an increase in IPL energy density($J/cm^2$) and a decrease in the distance between the sample surface and the lamp. In addition, temperature increases on the fish fillets during the treatments were well controlled within the range of 5.7~$9.8^{\circ}C$. The IPL treatment had a significant positive effect on the storage stability of seafood products at the storage temperature of $4^{\circ}C$ for 12 days. These results suggest that the storage period for fish fillets can be extended from 4 days to 6~8 days through the IPL treatment.
